Therefore, in the following, common reference numerals are given to those similar components, and redundant description is omitted.

(First Embodiment) FIGS. 1 to 4 show a first embodiment of the present invention. FIG. 1 is a sectional view of a water purifier, FIG. 2 is a sectional view of a water purification cartridge, and FIG. 4 is an exploded perspective view of the cartridge, FIG. 4 is a perspective view of the water purification cartridge, (a) shows a state where the first water inlet is opened by the movable member, and (b) is about half the first water inlet. It is a figure which shows the state shielded.

First, with reference to FIG. 1, the schematic structure of the water purifier 1 concerning this embodiment is demonstrated. This water purifier 1 is configured as a pot-type water purifier. A substantially bottomed cylindrical partition wall body 3 is accommodated in the cylinder of the substantially bottomed cylindrical pot case 2, and the partition wall body 3 forms approximately the upper half of the cylinder of the pot case 2. It is partitioned into a raw water chamber 4 and a water purification chamber 5 that forms approximately half of the lower side.

The bottom wall 3 a of the partition wall 3 is formed with a substantially cylindrical recess 3 b that is recessed downward. A substantially cylindrical water purification cartridge 6 is inserted into the recess 3b from the top to the back and fitted. An opening 3d is formed in the back wall 3c of the recess 3b.

In the state where the water purification cartridge 6 is fitted in the recess 3b, the upper part 6a of the water purification cartridge 6 is exposed in the raw water chamber 4, and the first water inlet 7a and the second water inlet 7b formed in the case 7 at the upper part 6a. Is facing the raw water chamber 4. The second water inlet 7b is installed in the vicinity of the bottom wall 3a. In this state, the lower end portion 6b of the water purification cartridge 6 is exposed in the water purification chamber 5 from the opening 3d, and the outlet 7c formed in the case 7 faces the water purification chamber 5 at the lower end portion 6b. Yes. The raw water in the raw water chamber 4 is introduced into the water purification cartridge 6 from the first water inlet 7a and the second water inlet 7b, and after being purified at least, is discharged into the water purification chamber 5 from the outlet 7c.

Above the raw water chamber 4, a ceiling wall 8 with a water supply port 8a is disposed. The water supply port 8a is closed so as to be openable and closable by a top-opening type lid 9 that is rotatably attached to the top wall 8. The raw water is supplied into the raw water chamber 4 through the water supply port 8a with the lid 9 opened upward.

Further, a passage 10 extending upward from the water purification chamber 5 is formed between the side wall 3e of the partition wall 3 and the pot case 2, and the pot case 2 or the top wall 8 has an upper end portion of the passage 10. A water inlet 10a is formed at the position. In the present embodiment, the pot case 2 is tilted so that the water injection port 10a is downward (in FIG. 1, the pot case 2 is tilted clockwise), and the purified water stored in the water purification chamber 5 is collected. The water is discharged from the water inlet 10a through the passage 10. In the present embodiment, the water inlet 10a is closed so as to be openable and closable by a top-opening type lid 11 that is rotatably supported by the pot case 2 or the top wall 8. In this case, when the pot case 2 is tilted, the lid 11 can be rotated by its own weight, dynamic pressure of water, or the like to open the water inlet 10a.

Next, the configuration of the water purification cartridge 6 will be described with reference to FIGS. The water purification cartridge 6 is formed in a substantially cylindrical shape, and the cylindrical central axis Ax (see FIGS. 1 and 2) is used in a posture along the vertical direction. The case 7 has an upper case 12 that forms an upper part in use and a lower case 13 that forms a lower part. The lower edge of the upper case 12 and the upper edge of the lower case 13 are connected to each other to form a substantially cylindrical outer shape. Presents. In the following, the vertical direction, the axial direction, the circumferential direction, and the radial direction are defined based on the cylindrical shape of the water purification cartridge 6 in the use state.

The inside of the case 7 is roughly divided into three spaces in the vertical direction (axial direction) by a partition wall 14 and a sheet 15 disposed below the partition wall 14 with a space therebetween. The upper portion is an additive storage chamber S1 for storing the additive 16, the lowermost portion is a purification chamber S2 for purifying water, and the intermediate portion is an intermediate chamber S3 as a mixing portion.

The additive storage chamber S <b> 1 is formed by being surrounded by the upper case 12 and the partition wall 14. The upper case 12 includes a peripheral wall 12a (first cylindrical side wall) that forms the upper part of the peripheral wall of the case 7, a top wall 12b that forms the top wall of the case 7, and a central axis Ax of the water purification cartridge 6 from the center of the top wall 12b. , And an inner cylinder 12c extending downward substantially along. A partition wall 14 is attached to the upper case 12 so as to close the lower part in the cylinder. In other words, in the present embodiment, the additive storage chamber S1 is formed in the cylinder of the upper case 12 as a space having a substantially annular cross section surrounded by the peripheral wall 12a, the top wall 12b, the inner cylinder 12c, and the partition wall 14. Yes. In this additive storage chamber S1, an additive 16 such as granular calcium having a diameter of about several millimeters is stored.

A substantially rectangular first water inlet 7a is formed in the peripheral wall 12a as shown in FIGS. The first water inlet 7a is stretched with a water-permeable mesh 17 by insert molding or the like, so that the additive 16 is prevented from spilling out of the first water inlet 7a. The inner cylinder 12c is formed with a slit-shaped notch 12d extending upward from the lower end thereof. The width of the notch 12d is set to be smaller than the particle diameter of the additive 16, thereby suppressing the additive 16 from flowing out of the notch 12d. In the present embodiment, the position in the axial direction of the upper edge 12e of the notch 12d and the position in the axial direction of the upper edge 12f of the first water inlet 7a are substantially the same.

A projecting portion 14b that projects upward in a substantially conical shape is formed at the center portion of the bottom wall portion 14a of the partition wall 14, and the projecting portion 14b projects upward and projects into the inner cylinder. A cylindrical portion 14c through which 12c is inserted is formed. The bottom wall portion 14a is formed with a plurality of slits 14d extending radially from the central axis Ax of the water purification cartridge 6 as outlets from the additive storage chamber S1. The width of the slit 14d is also set to be smaller than the particle diameter of the additive 16, thereby suppressing the additive 16 from flowing out of the slit 14d.

In the additive storage chamber S1 having the above configuration, the additive 16 elutes into the raw water introduced from the raw water chamber 4 into the additive storage chamber S1 through the first water inlet 7a, and water to which the additive has been added. Flows out from the additive storage chamber S1 through the slit 14d of the partition wall 14 into the intermediate chamber S3.

Here, in the present embodiment, an air reservoir Aa for confining air is formed in the upper portion of the additive storage chamber S1, and thereby, the additive 16 existing in the air reservoir Aa, that is, in the upper portion of the additive storage chamber S1. Do not immerse in water. That is, the concave portion 18 constituted by the peripheral wall 12a, the top wall 12b, and the inner cylinder 12c is only opened downward, and since there is no air passage upward, it is added from the first water inlet 7a. Even when water enters the agent storage chamber S1 and all of the upper part 6a of the water purification cartridge 6 is immersed in the water stored in the raw water chamber 4 (that is, in a submerged state), air accumulates in the recess 18, It is possible to prevent the additive 16 from being wet in the air reservoir Aa. In the present embodiment, normally, the positions of the notches 12d and the

upper edges

12e, 12f of the first water inlet 7a are the upper limit L of the flooded area Aw, and the additive 16 positioned below the upper limit L is immersed in water. The additive 16 positioned above the upper limit L is not immersed in water.

In such a configuration, when the additive 16 located below is immersed in water and eluted, the additive 16 located above falls downward due to gravity and is automatically supplied to the flooded area Aw. Therefore, since the additive 16 accommodated in the additive accommodating chamber S1 can be used sequentially from the one arranged on the lower side, the additive accommodated in the water purification cartridge is totally submerged or submerged. Compared to the configuration, the usable period of the additive 16 can be made longer, and the concentration difference of the additive can be more easily suppressed between the initial stage of use of the water purification cartridge 6 and the latter stage of use. Moreover, according to this embodiment, the immersion height of the additive 16 can be set according to the height of the flooded area Aw, and thereby the maximum value of the additive concentration can be set. That is, it is possible to suppress the additive 16 from dissolving in water more than necessary.

As shown in FIGS. 3 and 4, a plurality of second water inlets 7b are formed at substantially constant intervals in the circumferential direction at the lower part of the peripheral wall 12a of the upper case 12 forming the peripheral wall of the intermediate chamber S3. Therefore, raw water is introduced into the intermediate chamber S3 from the raw water chamber 4 through the second water inlet 7b, and water to which the additive is added from the additive storage chamber S1 through the slit 14d, These waters are introduced into the purification chamber S2 (the adsorption treatment chamber S21) disposed below the intermediate chamber S3. That is, in this embodiment, the raw water introduced from the second water inlet 7b to the intermediate chamber S3 bypasses the additive storage chamber S1. In this way, by dividing the water flowing through the additive storage chamber S1 and the water bypassing the additive storage chamber S1, the flow rate of the water flowing through the additive storage chamber S1 and the additive storage chamber S1 are reduced. The flow rate of the water to be bypassed can be set independently, so that the adjustment accuracy of the additive concentration can be easily increased. As described above, water is introduced into the intermediate chamber S3 from the second water inlet 7b and, as described above, water is introduced from the first water inlet 7a through the additive storage chamber S1. Therefore, the intermediate chamber S3 mixes the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b.

In the present embodiment, the second water inlet 7b is disposed below the first water inlet 7a. For this reason, the water head difference by the height difference of the 1st water inlet 7a and the 2nd water inlet 7b, and the 2nd water inlet in the position close | similar to the bottom wall 3a of the partition body 3 at the time of being initially supplied to the raw | natural water chamber 4 Due to the dynamic pressure of water reaching 7b, water is more likely to enter from the second water inlet 7b than the first water inlet 7a. Therefore, especially at the beginning when the raw water chamber 4 is supplied with water, the flow rate of water at the first water inlet 7a can be relatively reduced, and the flow rate of water in the additive storage chamber S1 can be adjusted to be small.

Moreover, in this embodiment, since additive storage chamber S1 was arrange | positioned above the 2nd water inlet 7b, after the water level of the raw | natural water chamber 4 became lower than the lower end of the additive storage chamber S1, from the 2nd water inlet 7b. Only water will flow into the water purification cartridge 6 and will not pass through the additive storage chamber S1 and will not contain the additive 16 and will be downstream from the intermediate chamber S3 (in the intermediate chamber S3, the purification chamber S2, etc.). Thus, the discharge of the additive 16 can be promoted to prevent the additive 16 from remaining. Therefore, at the time of the next use, it is suppressed that the additive concentration becomes higher than the set value due to the remaining additive 16, and the desired additive concentration is easily obtained.

The purification chamber S2 disposed below the intermediate chamber S3 is partitioned in a radial direction by a substantially cylindrical cylindrical body 19 disposed at a position along the central axis Ax of the water purification cartridge 6. In the present embodiment, The outer peripheral side of the cylinder 19 is an adsorption processing chamber S21 in which an adsorbent (eg, granular or powdered activated carbon) 20 is accommodated, and the inside of the cylinder 19 is a hollow filter material (eg, an inverted U-shaped curve). A filtration processing chamber S22 in which a thread membrane 21) is accommodated. In such a configuration, the water introduced from the intermediate chamber S3 is discharged from the outlet 7c of the lower end portion 6b via the adsorption processing chamber S21 and the filtration processing chamber S22 in this order. The cylindrical body 19 is fitted into a recessed portion 13b that is recessed downward formed in the center portion of the bottom wall 13a of the lower case 13 that forms the bottom wall of the case 7, and thereby, in the vertical direction along the central axis Ax of the water purification cartridge 6. It is erected.

The adsorption processing chamber S21 is surrounded by the peripheral wall 13c of the lower case 13 forming the lower peripheral wall of the case 7, the cylindrical body 19, the bottom wall 13a, and the sheet 15, and is formed in a cylindrical shape having a substantially annular cross section. The sheet | seat 15 can be comprised, for example with a nonwoven fabric. In this embodiment, the sheet 15 is formed in a ring shape and surrounds the cylinder 19, and the outer edge portion 15 a is fixed to the case 7 so as to be sandwiched between the upper case 12 and the lower case 13. On the other hand, the inner edge portion 15b is a free end so that water is introduced from the intermediate chamber S3 into the adsorption processing chamber S21 through a gap between the inner edge portion 15b and the cylindrical body 19. In addition, the sheet | seat 15 may be comprised with a water-permeable raw material, and you may make it permeate | transmit water. Further, in the present embodiment, the cap 22 is attached to the upper end of the cylindrical body 19, and the inner edge portion 15b of the sheet 15 is warped upward from the flange portion 22a by the flange portion 22a protruding from the cap 22 to the outside of the diameter. I am trying not to. With such a configuration, even when the water purification cartridge 6 is tilted or turned upside down with the water purification cartridge 1 removed from the water purifier 1, the sheet 15 is locked to the flange portion 22a and the gap is closed. It is possible to suppress the adsorbent 20 from leaking from S21 to the intermediate chamber S3 side.

A communication port 19a is formed in the lower portion of the cylindrical body 19, and the adsorption processing chamber S21 and the filtration processing chamber S22 are communicated with each other through the communication port 19a. The water removed by adsorbing impurities to the adsorbent 20 in the adsorption treatment chamber S21 is introduced into the filtration treatment chamber S22 through the communication port 19a.

In the filtration chamber S22, a large number of thin straw-shaped hollow fiber membranes as the filtering material 21 are bundled and accommodated in a state of being bent in a substantially inverted U shape. Water that has passed through the membrane wall of the hollow fiber membrane from the inside of the filtration processing chamber S22 and permeated into the membrane flows out into the lower end portion of the filtration processing chamber S22 through the membrane, and flows out from the outlet 7c to the water purification chamber 5. . When water passes through the membrane wall of the hollow fiber membrane, impurities contained in the water are filtered. The hollow fiber membrane as the filter medium 21 is fixed to the cylindrical body 19 while being filled with an adhesive (not shown) below the communication port 19a, and is hollowed out from the filtration processing chamber S22 by this adhesive. Direct outflow is prevented without passing through the thread membrane.

As a result of intensive studies by the inventors on the water purification cartridge 6 having the above configuration, it has been found that the concentration of water additive changes according to the flow rate of water flowing in the additive storage chamber S1. As an example, in the case where a granular calcium agent is used as the additive 16, as the flow rate of the water flowing in the additive storage chamber S1 is increased, the stirring effect by the water flow is increased and mixed in the water in the additive storage chamber S1. The additive concentration of the water after the water that has passed through the additive storage chamber S1 and the water introduced into the water purification cartridge 6 from the second water inlet 7b merged, and thus the water purification cartridge 6 increases. It has been found that the additive concentration of water discharged from the plant increases. Therefore, in the present embodiment, the movable member 23 that variably sets the flow rate ratio between the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b according to the position with respect to the case 7 is attached to the case 7, By adjusting the position of the movable member 23, the additive concentration in the water (purified water) that has passed through the water purification cartridge 6 can be variably set. Specifically, in this embodiment, the opening area of the first water inlet 7a is variably set by the movable member 23, and the flow rate of the water flowing in the additive containing chamber S1 is changed, whereby the first water inlet The flow rate ratio between the water introduced from 7a and the water introduced from the second water inlet 7b is variably set.

In this embodiment, as shown in FIGS. 2 to 4, a substantially bottomed cylindrical movable member 23 that covers the outer periphery of the upper case 12 from above is attached so as to be rotatable along the circumferential direction of the upper case 12. is there. The peripheral wall 23a (second cylindrical side wall) of the movable member 23 covers the peripheral wall 12a of the upper case 12 with a slight gap, and moves along the peripheral wall 12a. The peripheral wall 23a is provided with a substantially rectangular notch 23c as an opening that extends upward from the lower edge 23b.

On the outer surface of the peripheral wall 12a of the upper case 12, a plurality of (three in the present embodiment) ridges 12g extending in the circumferential direction are provided substantially in parallel at regular intervals, while the inner surface of the peripheral wall 23a of the movable member 23 is provided. In the state where the projection 23d is provided and the movable member 23 is assembled to the upper case 12, the projection 23d is engaged with the projection 12g in the axial direction, and the projection 23d is guided in the circumferential direction by the projection 12g. ing. Further, the protrusion 12g is provided with a notch 12h that allows relative movement in the axial direction of the protrusion 23d. Therefore, as shown in FIG. 3, with the protrusion 23d and the notch 12h aligned, the upper case 12 and the movable member 23 are close to each other in the axial direction until they abut against each other, and then these are relatively rotated in the circumferential direction. Thus, the protrusion 23d is accommodated between the ridges 12g, and the movable member 23 can be assembled to the upper case 12 (case 7). The movable member 23 can be rotated along the circumferential direction of the upper case 12. . A plurality of protrusions are provided at predetermined intervals in the groove between the ridges 12g, and the protrusion is overcome at a predetermined position in the circumferential direction with respect to the first water inlet 7a of the movable member 23 to generate a click feeling. It is more preferable to set the opening area of the water port 7a as a guide.

In such a configuration, as shown in FIG. 4, when the circumferential position of the movable member 23 is changed, the area where the notch 23c and the first water inlet 7a overlap changes according to the amount of movement of the peripheral wall 23a, or Since the range of the first water inlet 7a covered by the peripheral wall 23a increases or decreases, the opening width w and the opening area of the first water inlet 7a (the width and area of the region facing the raw water chamber 4) can be variably set. . That is, the movable member 23 functions as a shielding member that shields the first water inlet 7a.

FIG. 4A shows a state where the entire first water inlet 7a is open. In this state, since the flow rate of water flowing into the additive storage chamber S1 from the first water inlet 7a is relatively large, the additive concentration of water flowing out of the additive storage chamber S1 becomes high.

FIG. 4B shows a state in which about half of the first water inlet 7a is closed by the peripheral wall 23a of the movable member 23 and about half is opened. In this state, compared with the case of FIG. 4A, the flow rate of water in the additive storage chamber S1 is reduced, and the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b As compared with the case of FIG. 4A, the flow rate ratio of the water introduced from the first water inlet 7a is lower, and accordingly, the additive concentration of the water flowing out from the additive storage chamber S1 is Lower.

Thus, according to the water purification cartridge 6 according to the present embodiment, the concentration of water additive is changed by changing the relative rotational position (lateral position) of the movable member 23 around the central axis Ax with respect to the case 7. Can be made.

In addition, when air is unintentionally collected between each part of the water purification cartridge 6, particularly the intermediate chamber S 3 and the sheet 15 and the adsorbent 20, the gravity applied to the water and the buoyancy of the air balance and the flow path of the water becomes air. Since it is blocked, it may not be possible to obtain a desired flow rate, and it may take time until purified water is obtained, or a desired additive concentration may not be obtained. Therefore, in this embodiment, an air vent passage is formed substantially along the central axis Ax of the water purification cartridge 6.

Specifically, a substantially cylindrical central tube portion 23f that extends downward and enters the tube of the inner tube 12c is formed in the center portion of the top wall 23e of the movable member 23, and the rear of the center tube portion 23f is formed. A through hole 23g penetrating the top wall 23e is formed on the side (upper side). This through hole 23g becomes an air vent hole of the water purification cartridge 6.

The cap 22 fitted to the upper end of the cylindrical body 19 has a conical portion 22b that becomes thinner as it goes upward, and a cylindrical portion 22c that extends upward from the top of the conical portion 22b. The front end extends to the vicinity of the lower end of the central cylinder portion 23f. Therefore, the air in the filtration chamber S22 is discharged from the through hole 23g through the insides of the conical portion 22b, the cylindrical portion 22c, and the central cylindrical portion 23f.

The air in the adsorption processing chamber S21 and the intermediate chamber S3 moves to the central axis Ax side of the water purification cartridge 6 while rising along the protruding portion 14b of the partition wall 14, enters the cylinder of the inner cylinder 12c through the notch 12d, Furthermore, it enters the cylinder of the central cylinder part 23f from the opening at the lower end of the central cylinder part 23f, and is discharged from the through hole 23g.

Except for the air accumulated in the air reservoir Aa, the air in the additive storage chamber S1 is discharged from the through hole 23g through the notch 12d, through the cylinder of the inner cylinder 12c, and the cylinder of the central cylinder portion 23f.

As described above, in the present embodiment, the case 7 introduces water into the purification chamber S2 bypassing the first water inlet 7a for introducing water into the additive chamber S1 and the additive chamber S1. The second water inlet 7b and the intermediate chamber S3, which is a mixing section for mixing the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b, are formed in the case 7, A movable member 23 that variably sets the flow rate ratio between the water introduced from one water inlet 7 a and the water introduced from the second water inlet 7 b depending on the position with respect to the case 7 was attached. Therefore, the additive concentration can be easily variably set by the movable member 23 without replacing the water purification cartridge 6. In addition, when calcium etc. are used as an additive, the hardness of water can be variably set.

Moreover, in this embodiment, the 1st water inlet 7a is formed in the surrounding wall 12a of the upper case 12 as an outer wall of the case 7, and the 1st water inlet 7a is plugged up with the surrounding wall 23a of the movable member 23 which covers the outer side of the surrounding wall 12a. I did it. Therefore, by variably setting the opening area of the first water inlet 7a by the movable member 23, the additive concentration can be variably set, and the movable member 23 is disposed so as to cover the outside of the case 7, The user can easily operate the movable member 23.

In the present embodiment, at least the upper part of the case 7 is formed in a substantially cylindrical shape, the first water inlet 7a is formed in the peripheral wall 12a, and the movable member 23 is formed in a bottomed cylindrical shape that covers the case 7 from above. Then, the first water inlet 7 a is closed by the peripheral wall 23 a of the movable member 23 by rotating around the case 7. Therefore, the movable member 23 can be obtained with a relatively simple configuration, and the movable member 23 can be supported more stably on the case 7. Moreover, the opening area of the first water inlet 7a can be changed and the additive concentration can be changed by a relatively simple operation of rotating the movable member 23 relative to the case 7 (moving it in the lateral direction). it can. Furthermore, when the water purification cartridge 6 is inserted and mounted in the pot case 2 of the water purifier 1 from above as in the present embodiment, the movable member 23 is operated from above while being mounted in the pot case 2. It is convenient to be able to do it.

In the present embodiment, the case 7 is provided with the second water inlet 7b that bypasses the additive storage chamber S1 and introduces water into the purification chamber S2. Therefore, by dividing the water that passes through the additive storage chamber S1 and the water that bypasses the additive storage chamber S1, the flow rate of the water flowing through the additive storage chamber S1 and the additive storage chamber S1 are bypassed. The flow rate of water can be set independently, so that the adjustment accuracy of the additive concentration can be easily increased.

In the present embodiment, the first water inlet 7a is disposed above the second water inlet 7b. For this reason, the water head difference by the height difference of the 1st water inlet 7a and the 2nd water inlet 7b, and the 2nd water inlet in the position close | similar to the bottom wall 3a of the partition body 3 at the time of being initially supplied to the raw | natural water chamber 4 Due to the dynamic pressure of water reaching 7b, the water is more likely to enter from the second water inlet 7b than the first water inlet 7a. Therefore, especially at the beginning when the raw water chamber 4 is supplied with water, the flow rate of water at the first water inlet 7a can be relatively reduced, and the flow rate of water in the additive storage chamber S1 can be adjusted to be small. Therefore, in the case of this embodiment, it becomes easy to adjust the additive concentration lower. Furthermore, according to this structure, it becomes easy to arrange | position the movable member 23 which changes the opening area of the 1st water inlet 7a in the upper part of the water purification cartridge 6. FIG. Therefore, when the water purification cartridge 6 is inserted and mounted in the pot case 2 of the water purifier 1 from above as in the present embodiment, the movable member 23 is operated from above while being mounted in the pot case 2. It is easy to do and is convenient.

In the present embodiment, the air reservoir Aa is formed in the upper part of the additive storage chamber S1, and the additive 16 is introduced through the first water inlet 7a in the submerged area Aw below the air reservoir Aa. It was immersed in water, and the additive 16 was accommodated in the additive accommodating chamber S1 from the portion that becomes the water immersion area Aw to the portion that becomes the air reservoir Aa. In such a configuration, the additive 16 in the air reservoir Aa can be maintained without being submerged or flooded. When the additive 16 in the water immersion area Aw is immersed in water and eluted, the additive 16 positioned above the water drops downward due to gravity and is automatically supplied to the water immersion area Aw. Therefore, since the additive 16 accommodated in the additive accommodating chamber S1 can be used sequentially from the one arranged on the lower side, the additive accommodated in the water purification cartridge is totally submerged or submerged. Compared to the configuration, the usable period of the additive 16 can be made longer, and the change in the concentration of the additive can be suppressed to be smaller between the initial use stage and the later use stage of the water purification cartridge 6.

(Second Embodiment) FIGS. 5 to 7 show a second embodiment of the present invention. FIG. 5 is an exploded perspective view of a water purification cartridge according to the present embodiment, and FIG. FIG. 7 is a perspective view of the water purification cartridge, and FIG. 7A is a view showing a state where the first water inlet is opened by the movable member, and FIG. FIG.

The water purification cartridge 6A according to the present embodiment can be used by being attached to the water purifier 1 instead of the water purification cartridge 6 according to the first embodiment.

Similarly to the water purification cartridge 6 of the first embodiment, the water purification cartridge 6A also changes the opening area of the first water inlet 7aA formed in the case 7A by the movable member 23A so that the water flow rate in the additive storage chamber S1 is changed. By changing, the flow rate ratio of the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b is changed, and thus the additive concentration is changed. Also in the present embodiment, the substantially bottomed cylindrical movable member 23A is rotatably attached so as to cover the case 7A from above, and the relative angle of the movable member 23A with respect to the case 7A is changed. The area of the water port 7aA is changed.

However, in this embodiment, the first water inlet 7aA is divided into a plurality of water inlets 70a, and the number of water inlets 70a shielded (opened) by the movable member 23A can be variably set. Specifically, on the peripheral wall 12a of the upper case 12A, a plurality of slit-shaped water inlets 70a that are elongated along the circumferential direction are arranged in parallel at a constant pitch in the vertical direction (four in the present embodiment), from above. The length of the water inlet 70a is increased as it goes downward. Therefore, as shown in FIG. 7, the number of water inlets 70a to be shielded varies depending on the rotational position of the movable member 23A. For example, in the state of FIG. 7A, all the four water inlets 70a are opened, and in the state of FIG. 7B, the upper two water inlets 70a are shielded and the lower water inlet 70a is opened. Open (partially).

Therefore, according to this embodiment, it becomes easy for a user to visually recognize the opening area of the first water inlet 7aA as the number of water outlets 70a exposed to the outside. The effect that it becomes easy to recognize is acquired.

Further, in the present embodiment, a locking mechanism 24 that locks the movable member 23A to the case 7A is provided at a position where the shielding number of the water inlet 70a is switched. Specifically, on the outer surface of the peripheral wall 12a of the upper case 12A, a groove 24a is provided along the circumferential direction, while a protrusion 24b is provided on the inner surface of the peripheral wall 23a of the movable member 23A, and the groove 24a extends the protrusion 24b in the circumferential direction. Configure to guide. And the protrusion 24c which hold | maintains the protrusion 24b in a predetermined position is provided in the groove | channel 24a, and this protrusion 24c is arrange | positioned suitably, and several places (this embodiment) the movable member 23A switch the number of shielding of the water inlet 70a. Then, it can be stopped at four places in the circumferential direction. The protrusion 24b is maintained at a position sandwiched between the end wall and the protrusion 24c at both ends of the groove 24a, and is maintained at a position sandwiched between the pair of

protrusions

24c and 24c at an intermediate position of the groove 24a. .

According to this configuration, when the protrusion 24b gets over the protrusion 24c, the user who operates the movable member 23A can be given a click feeling, and the effect that the movable member 23A can be easily set at a predetermined position can be obtained. .

(Third Embodiment) FIGS. 8 to 10 show a third embodiment of the present invention. FIG. 8 is an exploded perspective view of a water purification cartridge according to this embodiment, and FIG. 9 is a perspective view of the water purification cartridge. (A) is a diagram showing a state in which the first water inlet is closed by the movable member, (b) is a diagram showing a state in which the first water inlet is shielded by about half, and (c) is a diagram showing the first guide. FIG. 10 is a cross-sectional view of the water purification cartridge, in which FIG. 10 is a sectional view of the water purification cartridge, in which (a) is a diagram showing a state where the first water inlet is closed by a movable member, and (b) is the first guide. The figure which shows the state by which the water mouth was shielded about half, (c) is a figure which shows the state by which the 1st water inlet was open | released.

The water purification cartridge 6B according to the present embodiment can be used by being attached to the water purifier 1 instead of the water purification cartridge 6 according to the first embodiment.

Further, similarly to the water purification cartridge 6 of the first embodiment, the water purification cartridge 6B also changes the opening area of the first water inlet 7a formed in the case 7B by the movable member 23B, and the water in the additive storage chamber S1. By changing the flow rate, the flow rate ratio between the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b is changed, thereby changing the additive concentration.

However, in this embodiment, the movable member 23B is attached to the case 7B so that the vertical position of the movable member 23B can be variably set, and the vertical position of the movable member 23B is variably set, thereby opening the first water inlet 7a. The height h (see FIG. 9) is changed. Specifically, as shown in FIG. 8, a height adjusting mechanism 25 is configured by a groove 25a provided on the peripheral wall 12a of the upper case 12B (case 7B) and a protrusion 25b provided on the inner surface of the movable member 23B. It is. The groove 25a includes a vertical groove 25c extending downward from the upper end of the peripheral wall 12a and a plurality of horizontal grooves 25d extending from the vertical groove 25c toward one side in the circumferential direction (left side in FIG. 8). The horizontal grooves 25d are arranged in a plurality (five in this embodiment) at a constant pitch (equal intervals). Therefore, the height of the movable member 23B is obtained by lowering the movable member 23B along the protrusion 25b along the vertical groove 25c, rotating the movable member 23B in the circumferential direction, and inserting the protrusion 25b into any of the horizontal grooves 25d. Can be variably set in a plurality of stages (5 stages in the present embodiment). It is preferable that a protrusion 25e is formed on the back side of the horizontal groove 25d so that the protrusion 25b can be easily maintained at the innermost part of the horizontal groove 25d, and a click feeling is generated by getting over the protrusion 25b.

With this configuration, as shown in FIGS. 9 (a) to 9 (c), the opening height h of the first water inlet 7a is variably set, thereby changing the flow rate of water in the additive storage chamber S1. The flow rate ratio between the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b can be changed to change the additive concentration.

In the present embodiment, the height of the upper limit L of the flooded area Aw in the additive containing chamber S1 can be changed by the movable member 23B. In the present embodiment, the lower end 23h of the central cylindrical portion 23f of the movable member 23B and the lower edge 23b of the peripheral wall 23a are set to the same height. Therefore, the annular recess 23i between the peripheral wall 23a of the movable member 23B and the central cylindrical portion 23f becomes an overall air reservoir, and the positions of the lower end 23h and the end edge 23b become the upper limit L of the flooded area Aw. As shown in FIGS. 10A to 10C, the amount of the additive 16 immersed in water is changed by variably setting the height of the movable member 23B. The agent concentration can be varied. Therefore, in the present embodiment, the actual additive concentration is determined by the height of the upper limit L and the opening area (opening height h) of the first water inlet 7a.

And in the structure of this embodiment, as shown to (a) of FIG. 9 and FIG. 10, while closing the 1st water inlet 7a with the movable member 23B, the upper limit of the water immersion area | region Aw is made into the lower end of additive storage chamber S1 ( By setting the position lower than the upper surface of the partition wall 14, the additive 16 can be obtained in a state where the additive concentration is almost zero without being immersed in water.

As described above, in this embodiment, the movable member 23B is attached to the case 7B so that the vertical position of the movable member 23B can be variably set, and the vertical position of the movable member 23B is variably set. The opening height of the water inlet 7a was changed. Also with this configuration, the opening area of the first water inlet 7a can be variably set, whereby the flow rate of water in the additive storage chamber S1 can be variably set. Therefore, the additive concentration can be variably set by changing the flow rate ratio between the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b. Moreover, since the protrusion amount from the case 7B of the movable member 23B changes, there exists an advantage that it becomes easy for a user to visually recognize the change of opening area. Furthermore, in this embodiment, since the upper limit L of the flooded area Aw can be changed as the height position of the movable member 23B is changed, the additive concentration can be variably set using this point. it can.

FIG. 11 is a cross-sectional view of a water purification cartridge according to a modification of the third embodiment.

The water purification cartridge 6C according to this modification is provided with a pressing mechanism 26 that presses the additive 16 downward toward the flooded area Aw. The pressing mechanism 26 includes a top plate 26a placed on the granular additive 16, and a coil spring as a biasing mechanism that is housed in the recess 18 of the upper case 12B and biases the top plate 26a downward. 26b, and the additive 16 is pressed downward through the top plate 26a by the compression reaction force of the coil spring 26b.

According to such a configuration, the additive 16 on the upper side can be moved downward more reliably by the pressing mechanism 26 in accordance with the elution of the additive 16 in the submerged area Aw. Thus, the filling density of the additive 16 in the flooded area Aw can be increased. In addition, the change in the density of the additive 16 in the submerged area Aw during the use period of the water purification cartridge 6 can be reduced to suppress the fluctuation of the additive concentration.

(Fourth Embodiment) FIGS. 12 and 13 show a fourth embodiment of the present invention, and FIG. 12 is a sectional view of a water purification cartridge showing a state in which the movable member is arranged at the lowest position. FIG. 13 is a cross-sectional view of the water purification cartridge and shows a state in which the movable member is disposed at the uppermost position.

The water purification cartridge 6D according to the present embodiment can also be used by being attached to the water purifier 1 instead of the water purification cartridge 6 according to the first embodiment.

The water purification cartridge 6B according to the present embodiment includes a movable member 27. Then, the water purification cartridge 6B variably sets the communication area between the first water inlet 7a and the additive storage chamber S1 by changing the vertical position of the lower wall 27a of the additive storage chamber S1 by the movable member 27. Thus, the flow rate ratio between the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b is variably set.

Specifically, the movable member 27, like the partition wall 14, closes the lower part of the additive storage chamber S1 and has a lower wall 27a having a slit 27c serving as an outlet, and extends upward from the lower wall 27a to the upper case 12B ( A leg portion 27b exposed to the outside of the upper case 12B from a slit 12j formed in a stepped portion of the case 7B). The leg 27b extends along the outer surface of the peripheral wall 12a of the upper case 12B, and is similar to that shown in FIG. 8 between the inner surface of the leg 27b and the outer surface of the peripheral wall 12a of the upper case 12B. A height adjusting mechanism 25 is provided. In addition, the leg part 27b and the slit 12j which penetrates this are provided with multiple (for example, three every 120 degrees) by the fixed interval along the circumferential direction.

The first water inlet 7a is provided below the step portion of the peripheral wall 12a (below the upper limit L). A slit 27d that overlaps the first water inlet 7a is formed in the leg portion 27b. Accordingly, the first water inlet 7a can communicate with the additive storage chamber S1 through the slit 27d. In addition, you may provide the 1st water inlet 7a in the position without the leg part 27b.

In such a configuration, the communication area between the first water inlet 7a and the additive storage chamber S1 can be changed by moving the movable member 27 up and down to change its vertical position. In the state shown in FIG. 12, the movable member 27 is on the lower side, and the entire area of the first water inlet 7a communicates with the additive storage chamber S1. In the state shown in FIG. 13, the region that communicates with the additive storage chamber S <b> 1 in the first water inlet 7 a corresponds to the portion where the movable member 27 is above and the additive 16 is generally located above in the case of FIG. 12. It has decreased compared to. Incidentally, in this embodiment, in the state of FIG. 13, the communication area between the first water inlet 7a and the slit 27d is 0, and the additive concentration is also 0.

In such a configuration, the concave portion 18 of the upper case 12B becomes the air reservoir Aa, and the additive 16 above the upper limit L of the flooded area Aw (that is, in the air reservoir Aa) is not flooded or flooded, and the upper limit L Only the additive 16 below is immersed in water. The upper limit L in the present embodiment is the position of the upper edge 12e of the notch 12d formed in the inner cylinder 12c. The upper limit L of the flooded area Aw, that is, the position serving as the lower limit of the air reservoir Aa is unchanged even when the vertical position of the movable member 27 relative to the upper case 12B is changed by the height adjusting mechanism 25 described above. However, by variably setting the position of the lower wall 27a in the vertical direction, the additive 16 (the storage area thereof) moves up and down in the additive storage chamber S1, and the additive 16 immersed in water in the additive storage chamber S1. The height, that is, the immersion height D can be variably set.

As described above, in the embodiment, the movable member 27 changes the vertical position of the lower wall 27a of the additive storage chamber S1 to change the communication area between the first water inlet 7a and the additive storage chamber S1. The flow rate ratio between the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b was variably set. Therefore, since the flow rate ratio between the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b can be variably set by the movable member 27, the additive concentration can be easily variably set. it can.

(Fifth Embodiment) FIGS. 14 and 15 show a fifth embodiment of the present invention. FIG. 14 is a perspective view of a water purification cartridge, and FIG. 15 is a cross-sectional view of the water purification cartridge. In FIG. 15 and subsequent figures, the additive, adsorbent and filter medium are omitted.

The water purification cartridge 6E according to the present embodiment can also be used by being attached to the water purifier 1 instead of the water purification cartridge 6 according to the first embodiment.

Similarly to the water purification cartridge 6 of the first embodiment, the water purification cartridge 6E also variably sets the flow rate ratio between the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b by the movable member 23E. Thus, the additive concentration is changed. However, in the present embodiment, the movable member 23 variably sets the opening area of the second water inlet 7b instead of the first water inlet 7a.

In the present embodiment, the second water inlet 7b is formed in the lower portion of the peripheral wall 12a of the upper case 12 along the circumferential direction. A water-permeable mesh 17 is stretched on the second water inlet 7b by insert molding or the like.

The movable member 23E is formed in a cylindrical shape and is attached to the lower portion of the peripheral wall 12a of the upper case 12. The movable member 23E is fitted to the upper case 12 so as to be rotatable along the circumferential direction of the upper case 12. The peripheral wall 23aE (second cylindrical side wall) of the movable member 23E covers the peripheral wall 12a of the upper case 12 with a slight gap, and the peripheral wall 23aE serves as an opening upward from the lower edge 23bE. A substantially rectangular cutout 23cE is provided.

In such a configuration, when the circumferential position of the movable member 23E is changed, the area where the notch 23c and the second water inlet 7b overlap changes, and the opening width and area of the second water inlet 7b (facing the raw water chamber 4). The width and area of the region can be variably set. That is, the flow rate ratio between the water introduced from the first water inlet 7a and the water introduced from the second water inlet 7b can be variably set by the movable member 23E. Thereby, the additive density | concentration in the water (purified water) which passed the water purification cartridge 6 can be variably set.

As described above, in the present embodiment, the movable member 23E variably sets the opening area of the second water inlet 7b. Therefore, by changing the position of the movable member 23E and variably setting the opening area of the second water inlet 7b, the additive concentration can be easily variably set as in the first embodiment.

(Sixth Embodiment) FIGS. 16 to 22 show a sixth embodiment of the present invention. FIG. 16 is a sectional view of a water purification cartridge, and FIG. 17 is a plan view of the water purification cartridge. ) Is a diagram showing a state in which the entire outlet is overlapped with the second water inlet, (b) is a diagram showing a state in which the entire outlet is displaced from the second water inlet, and FIG. 18 is a cross-sectional view showing the addition portion of the water purification cartridge 19 is a bottom view showing an addition part of the water purification cartridge, FIG. 20 is a sectional view taken along line XX-XX in FIG. 19, FIG. 21 is a sectional view showing the purification part of the water purification cartridge, and FIG. It is a top view which shows the purification | cleaning part.

Although the water purification cartridge 6F of this embodiment is provided with the structure similar to the water purification cartridge 6 of 1st Embodiment, as shown to FIG. 16 and FIG. 17, the addition part 30 which has additive storage chamber S1 is purification chamber S2. It is connected by a connecting part 32 so as to be rotatable (movable) with respect to the purifying part 31 having the. In the present embodiment, the movable member 23 of the first embodiment is not provided.

As shown in FIGS. 18 and 19, the addition unit 30 includes an upper case 12F, an additive storage chamber S1, a first water inlet 7a, a second water inlet 7b, and a partition wall 14 that functions as a bottom wall. It has.

One outlet 14dF (FIG. 19) is formed in the bottom wall portion 14a of the partition wall 14 for leading the water in the additive storage chamber S1 to a mixing water inlet 33a (to be described later) of the purification unit 31. The outlet 14 dF is extended along the circumferential direction of the case 7. A water-permeable mesh 17 is stretched at the outlet 14dF by insert molding or the like, so that the additive 16 is prevented from spilling out of the outlet 14dF. Moreover, the protrusion part 14bF of the partition 14 is formed in circular arc shape along the rotation direction of the addition part 30 with respect to the purification | cleaning part 31, as shown in FIG.

As shown in FIGS. 21 and 22, the purification unit 31 includes a lower case 13F, a purification chamber S2, a ceiling wall 33 (planar wall) that closes the upper surface of the lower case 13F, a cylindrical body 19, and a cap 22. A water inlet 33a. The purification unit 31 is formed larger than the addition unit 30 in plan view. The ceiling wall 33 functions as the ceiling wall of the purification chamber S2.

The mixing water inlet 33a is formed in the top wall 33 and penetrates the top wall 33 in the vertical direction. The mixing water inlet 33a is disposed below the outlet 14dF and is capable of receiving water from above, and the water led out from the outlet 14dF and the water bypassing the additive storage chamber S1 are purified. To be introduced. The mixed water inlet 33a is stretched with a water-permeable mesh 17 by insert molding or the like, and the adsorbent is prevented from flowing out of the mixed water inlet 33a.

The connecting portion 32 includes a support shaft 35 that is integrally formed with the lower case 13F, and an insertion hole 36 that is provided in the upper case 12F and into which the support shaft 35 is inserted. The support shaft 35 is erected in a direction (upward) substantially perpendicular to the top wall 33 at the upper end portion of the lower case 13F. The connecting portion 32 is connected to the purification chamber S2 (purification portion 31) about the support shaft 35 so that the additive storage chamber S1 (addition portion 30) can be rotated (moved) in the horizontal direction. The overlapping area in the vertical direction between the outlet 14dF and the mixed water inlet 33a is variably set. Specifically, the connecting portion 32 slides in the horizontal direction on the top wall 33 while the additive storage chamber S1 rotates around the support shaft 35, and as shown in FIG. It is possible to move between the state where the whole overlaps with the mixing water inlet 33a in the vertical direction and the state where the entire outlet 14dF is displaced in the vertical direction from the second water inlet as shown in FIG. Thus, the additive storage chamber S1 is connected to the purification chamber S2. The connecting portion 32 having such a structure variably sets the overlapping area in the vertical direction between the outlet 14dF and the mixed water inlet 33a, thereby allowing the water and the additive containing chamber S1 to flow into the mixed water inlet 33a from the outlet 14dF. The flow rate ratio with the water that bypasses and flows into the mixed water inlet 33a is variably set. As the water flowing around the additive storage chamber S1 and flowing into the mixed water inlet 33a, the water flowing into the mixed water inlet 33a through the second water inlet 7b and the raw water chamber 4 without going through the second water inlet 7b. And water flowing directly into the mixing water inlet 33a. Here, when the protruding portion 14bF of the partition wall 14 is formed in an arc shape along the rotation direction of the addition portion 30, the cap 22 is rotated when the additive storage chamber S1 is rotated with respect to the purification chamber S2. The cylindrical portion 22c is movable in the protruding portion 14bF.

In the water purification cartridge 6F having such a configuration, the amount of water flowing from the outlet 14dF to the mixed water inlet 33a is determined by the connecting portion 32 according to the overlapping area of the outlet 14dF and the mixed water inlet 33a in the vertical direction. The additive concentration of water flowing out from the outlet 7c of the water purification cartridge 6F is determined. Here, the state shown in FIG. 17A is a state in which the entire outlet 14dF overlaps the mixed water inlet 33a in the vertical direction. In this state, the water flowing into the mixed water inlet 33a from the outlet 14dF is in this state. While the amount is maximized, the amount of water that bypasses the additive storage chamber S1 and flows into the mixing water inlet 33a is minimized, and the concentration of the additive of water flowing out from the outlet 7c of the water purification cartridge 6F is maximized. On the other hand, the state shown in FIG. 17B is a state in which the entire outlet 14dF is displaced in the vertical direction from the second water inlet, and in this state, the amount of water flowing from the outlet 14dF to the mixed water inlet 33a. On the other hand, the amount of water flowing into the mixing water inlet 33a bypassing the additive storage chamber S1 is maximized, and the additive concentration of water flowing out from the outlet 7c of the water purification cartridge 6F is minimized. In addition, since the water which flows out from the outflow port 14dF and does not flow into the mixing water inlet 33a returns to the raw water chamber 4 of the pot case 2, it is prevented from being mixed with the water flowing out from the outflow port 7c of the water purification cartridge 6F.
