Description
- The present invention relates to a hand dryer that hygienically performs a drying process by jetting a high-speed airflow onto wet hands after having been washed.
- Conventionally, a hand dryer has been developed that hygienically performs a hand drying process, in which wet hands after having been washed are dried by blowing water away by jetting high-speed airflow, rather than being wiped on a towel or a handkerchief. As such the hand dryer, a hand dryer is disclosed that is provided with two air nozzle sections that jet high-speed airflows (for example, see Patent Document 1). The two air nozzle sections are provided on a near side and a far side of an opening of a hand drying chamber to face each other. Wind is simultaneously applied to both a palm and a back of a hand, so that water is blown away from the hand, thereby drying the hand.
- In addition, a hand dryer is disclosed that has a hand drying chamber including a hand insertion opening, a first wall section, a second wall section, and a pair of air nozzles. A left hand and a right hand can be inserted in parallel into the hand insertion opening. The first wall section faces backs of the left hand and the right hand that are inserted in parallel from the hand insertion opening. The second wall section faces palms of the left and the right hand, and the first wall section. The pair of air nozzles is arranged in respective centers of the first wall section and the second wall section to extend roughly along an overall length of the hands, almost in parallel with a direction of fingers of the left hand and the right hand inserted in parallel. The pair of air nozzles respectively jet high-speed airflows to the left and to the right to be almost parallel with the backs and the palms of the left hand and the right hand (for example, see Patent Document 2).

- Patent Document 2: Japanese Patent Application Laid-open No. 2005-087283 (p. 6, and FIGS. 1 to 5)
- However, the hand dryer disclosed in
Patent Document 1 is problematic in that the high-speed airflows jetted from the two opposing air nozzle sections collide with each other. Therefore, a disruption occurs in the airflows, thereby causing noise. - The hand dryer disclosed in
Patent Document 2 is problematic in that the pair of air nozzles respectively jet the high-speed airflows to the left and to the right to be roughly parallel with the palms and backs of the left hand and the right hand. Therefore, water on the hands is difficult to remove. In particular, the airflows do not pass between fingers. Therefore, water attached between the fingers is hardly removed. - The present invention has been achieved in light of the above-described problems. An object of the present invention is to provide a hand dryer that makes little noise and can remove even water attached between fingers.
- To solve the above problems and to achieve the above objects, a hand dryer according to the present invention includes a hand drying chamber that includes a hand insertion opening from which left and right hands can be inserted in parallel; a first wall section that faces backs of the hands inserted from the hand insertion opening; a second wall section that faces palms of the hands and the first wall section; and a pair of air nozzle sections that is set on any one of a side of the first wall section and a side of the second wall section to extend roughly along an overall length of the inserted hands in a direction almost parallel to a direction of a finger of each of the inserted hands, and that jets a high-speed airflow toward any one of the backs and the palms of the hands.
- According to the present invention, a hand dryer achieves advantageous effects in that the hand dryer makes little noise and removes even water attached between fingers.

-
FIG. 1 is a side view of a hand dryer according to a first embodiment of the present invention.FIG. 2 is a front view of the hand dryer according to the first embodiment. As shown inFIG. 1 andFIG. 2 , in ahand dryer 81 according to the first embodiment, ahand drying chamber 2 is formed in an upper portion of amain body casing 1. Thehand dryer 81 is used by fixing themain body casing 1 onto a wall surface, such as that of a rest room, through use of a screw and the like. - A
second wall section 3 is formed on an upper front side (user side) of themain body casing 1. Afirst wall section 4 is formed on an upper back side. Thehand drying chamber 2 is surrounded by aninner surface 5 of thesecond wall section 3, aninner surface 6 of thefirst wall section 4, and abottom surface 8. Thebottom surface 8 receives water droplets blown from hands. Ahand insertion opening 9 is formed in an upper portion of thehand drying chamber 2. Hands are inserted into and removed from thehand insertion opening 9. Lateral openingsections 10 are formed in both lateral directions. Thelateral opening sections 10 allow air to flow out after a hand drying process. - A high-pressure
airflow generating unit 11 is arranged in a lower portion of themain body casing 1. High-pressure airflows generated by the high-pressureairflow generating unit 11 are led toair nozzle sections 13 provided on thefirst wall section 4, by way of anairflow path 12 formed in thefirst wall section 4. - The hands of a user are inserted into the
hand drying chamber 2 at an angle, such that wrists are on a near side and fingertips are on a far side (rear side), in a state in which a left hand and a right hand of the user standing in front of themain body casing 1 are naturally aligned in parallel in a lateral direction. - The
air nozzle sections 13 are formed (set) projecting from theinner surface 6 of thefirst wall section 4, in positions respectively facing the left hand and the right hand that are inserted into thehand drying chamber 2. Longitudinal directions of theair nozzle sections 13 extend to be almost parallel with directions of respective fingers of the hands inserted in the vertical direction. Theair nozzle sections 13 are formed at a forward-tilt angle of 5 degrees to 45 degrees, such that upper portions are on the near side and lower portions are on the far side (rear side). The direction of a finger is approximately a direction of a middle finger when the hand is naturally spread. Theinner surface 5 of thesecond wall section 3 is formed at a forward-tilt angle, such that the hands can be easily inserted into thehand drying chamber 2 and a distance from theair nozzle sections 13 is almost constant. - The
hand dryer 81 is configured such that high-speed airflows 14 (wind speed: 50 m/s to 250 m/s) are jetted into thehand drying chamber 2 from theair nozzle sections 13. Water on the left hand and the right hand, inserted into thehand drying chamber 2, is blown towards theinner surface 5 of thesecond wall section 3. The water droplets that have been blown are collected on theinner surface 5 of thesecond wall section 3 and thebottom surface 8. The collected water droplets then pass through adrain 15 and adrain pipe 16, and are collected in adrain tank 17. Thedrain tank 17 can be attached and removed freely to and from themain body casing 1 by being slid forward and backward. A removal lid covers thedrain tank 17. - The high-pressure
airflow generating unit 11 includes a DC brushless motor (alternatively, an ordinary commutator motor or an induction motor can also be used), a motor driving circuit, and a turbo-fan driven by the DC brushless motor. The high-pressureairflow generating unit 11 is automatically operated by acontrol circuit 18. Anair inlet 19 of the high-pressureairflow generating unit 11 opposes aninlet passage 20 provided within themain body casing 1. Theair inlet 19 suctions external air from asuction opening 21 on a lower end of theinlet passage 20. Afilter 25 removes dust and moisture from the air suctioned from thesuction opening 21. The air is then supplied to the high-pressureairflow generating unit 11. - A
hand detecting sensor 22 is provided on theinner surface 6 of thefirst wall section 4. Whether the hands are inserted into thehand drying chamber 2 from thehand insertion opening 9 is detected by a detection signal from thehand detecting sensor 22. The detection signal from thehand detecting sensor 22 is input into thecontrol circuit 18 that includes a microcomputer. When thecontrol circuit 18 judges that the hands are inserted, thecontrol circuit 18 electrifies the high-pressureairflow generating unit 11 to jet the high-speed airflows 14 from theair nozzle sections 13. - When the left hand and right hand are inserted into the
hand drying chamber 2 from thehand insertion opening 9 of thehand dryer 81 in parallel up to the vicinity of the wrists in a natural state, thehand detecting sensor 22 detects insertion of the hands. The high-pressureairflow generating unit 11 operates under the control of thecontrol circuit 18. The high-speed airflow 14 is jetted from theair nozzle section 13 obliquely downward, towards a front side of thehand drying chamber 2. -
FIG. 3 is a side view of when the hands are inserted into the hand dryer according to the first embodiment and twisted.FIG. 4 is a longitudinal cross-sectional view of relative positions of the air nozzle sections of the hand dryer according to the first embodiment and the inserted hands. As shown inFIG. 3 andFIG. 4 , when the hands are twisted front and back, such that the palms are turned by flipping the wrists, the high-speed airflows 14 jetted from theair nozzle sections 13 come into contact with the entire hands and pass between the fingers, blowing water from the hands. -
FIG. 5 is a transverse cross-sectional view taken along line A-A inFIG. 1 . As shown inFIG. 5 , the high-speed airflows 14 that have come into contact with the hands, passed between the fingers, and blown the water droplets change directions of flow after coming into contact with theinner surface 5 of thesecond wall section 3. The high-speed airflows 14 then flow outside from thelateral opening sections 10. At this time, the blown water droplets are separated from the airflow by inertia force, because of the change in the direction of flow of the high-speed airflows 14. The water droplets run down theinner surface 5 of thesecond wall section 3 and thebottom surface 8, and are collected by the drain 15 (seeFIG. 2 ). The water droplets then pass through thedrain pipe 16 and are collected in thedrain tank 17. - The
second wall section 3 blocks the high-speed airflows 14 in front of the user. Therefore, the user is not exposed to the high-speed airflows 14 and the water droplets. After a hand drying process is completed and the hands are removed from thehand drying chamber 2, thehand detecting sensor 22 detects that the hands have been removed and stops the high-pressureairflow generating unit 11. - Next, the
air nozzle sections 13 will be explained in detail. When thehand dryer 81 is used, the hands of the user are inserted into thehand drying chamber 2 at an angle, such that the wrists are on the near side and the fingertips are on the far side (rear side), in a state in which the left hand and the right hand of the user standing in front of themain body casing 1 are naturally aligned in parallel in the lateral direction. - The
air nozzle sections 13 extend in the vertical direction on thefirst wall section 4 that faces each hand inserted into thehand drying chamber 2. Theair nozzle section 13 is arranged at a frontward tilt angle such that the upper portion is positioned towards the front side and the lower portion is positioned towards the far side (rear side). As a result of the positioning of theair nozzle sections 13, the high-speed airflows 14 jetted from theair nozzle sections 13 flow from the far side of thehand drying chamber 2 towards the near side, advancing obliquely downward, in a shape of an air curtain extending in the vertical direction. - The high-
speed airflows 14 come into contact with the entire hands at the same time, from the wrist to the fingertips of each hand. The high-speed airflows 14 also pass between the fingers. Therefore, when the front and the back of the hands are placed in contact with the high-speed airflows 14 by twisting the hands at the wrist, water on the front and the back of the hands and between the fingers are blown. Therefore, the entire hands can be dried without moving the hands in the vertical direction. - As shown in
FIG. 3 , theair nozzle sections 13 are respectively arranged in positions opposing the left hand and the right hand inserted into thehand drying chamber 2. Therefore, the distance between the hand and theair nozzle section 13 can be shortened. Theair nozzle section 13 is arranged at a forward-tilt angle such that the upper portion is positioned towards the near side and the lower portion is positioned towards the far side. Therefore, the distance between the hand and theair nozzle section 13 is almost constant from the wrist to the fingertips. As a result, the high-speed airflow 14 comes into contact with the entire hand at a constant speed, without reduction in flow rate and while maintaining high kinetic energy. Thus, water is efficiently and evenly removed from the hands. -
Air jet openings 24 of theair nozzle sections 13 face downward. Therefore, the water droplets within thehand drying chamber 2 are prevented from entering the main body casing 1 from theair jet openings 24. Theair nozzle sections 13 are provided only on thefirst wall section 4 side. No air nozzles are arranged on thesecond wall section 3 side. Therefore, collision between the jetted high-speed airflows 14 does not occur, so that noise caused by collision between high-speed airflows does not occur. Thus, thehand dryer 81 makes less noise. - The high-
speed airflow 14 is jetted obliquely downward and blows the water droplets in a direction along gravitational force. Therefore, water on the hands can be efficiently removed. Moreover, airflow after the hands are dried is also obliquely downward. As shown inFIG. 3 , the air flows from thehand drying chamber 2 downwards to thelateral opening sections 10, and does not flow out of thehand insertion opening 9. Therefore, the user is minimally exposed to wind and water droplets. - When the user standing in front of the
main body casing 1 naturally inserts both hands into thehand drying chamber 2 to be aligned in parallel in the lateral direction, the left hand and the right hand are roughly parallel or, as shown inFIG. 4 , the space between the left hand and the right hand is large on the wrist side and small on the fingertip side. Therefore, an angle formed by a pair of theair nozzle sections 13 is set to 0 degree to 60 degrees (a V-shape of about 20 degrees for an ordinary adult person) so that space between a pair of theair nozzle sections 13 in the lateral direction is formed to be large on a hand insertion side and small on the far side. As a result, the angle formed by the left hand and the right hand, and the angle formed by a pair of theair nozzle sections 13 match. Thus, the high-speed airflows 14 come into contact with the entire hands and between the fingers, resulting in high water-removal performance. - In a conventional hand dryer in which high-speed airflows are jetted from a pair of air nozzles arranged facing each other, the high-speed airflows come into simultaneous contact with the palm side and the back side of the hands. Therefore, in spaces between the fingers that are not blocked by the hands, each airflow collides with the opposing airflow. Thus, wind speed drops, causing a problem in that water on side surfaces of the fingers cannot be sufficiently removed.
- In the
hand dryer 81 according to the first embodiment, because a pair of theair nozzle sections 13 does not oppose each other, the high-speed airflows come into contact with every part of the hands while maintaining wind speed. Because theair nozzle sections 13 extend in the vertical direction, as shown inFIG. 5 , the jetted high-speed airflows 14 enter gaps between the fingers. Thus, water on the side surfaces of the fingers can be efficiently removed. - Next, an air jet opening of the
air nozzle section 13 will be explained in detail.FIG. 6 is a diagram of the air jet opening of the hand dryer according to the first embodiment.FIG. 7 is a diagram of a modified example of the air jet opening.FIG. 8 is a diagram of another modified example of the air jet opening.FIG. 9 is a diagram of still another modified example of the air jet opening.FIG. 10 is a side view of a modified example of the air nozzle section. - As shown in
FIG. 6 , in theair nozzle section 13 of the hand dryer according to the first embodiment, the long hole-shapedair jet openings 24 are successively arranged in a row forming a broken line. Theair nozzle section 13 achieves excellent drying performance and noise performance. As shown inFIG. 7 , the air jet opening can be a slit-shaped air jet opening 24 a. As shown inFIG. 8 , round hole-shapedair jet openings 24 b can be successively provided in a row forming a broken line. As shown inFIG. 9 , the long hole-shapedair jet openings 24 can be successively arranged in a plurality of rows forming broken lines. Theair nozzle section 13 is not necessarily required to be integrally formed. As shown inFIG. 10 , a plurality ofair nozzle sections 13 a can be successively arranged in a row forming a broken line. - A length of each row of the
air jet openings - As shown in
FIG. 5 , theair nozzle section 13 is formed to project from theinner surface 6 of thefirst wall section 4 of thehand drying chamber 2 so that the distance between the hand and theair nozzle section 13 is made small. Moreover, areas of thehand insertion opening 9 and thelateral opening sections 10 are made large. As a result, the wind speed of the air flow including the water droplets flowing from thehand drying chamber 2 decreases. Thus, an amount of water droplets flowing out of thehand drying chamber 2 can be reduced. - The
air nozzle section 13 is formed to project from theinner surface 6 of thefirst wall section 4. Therefore, thefirst wall section 4 does not block view, so that an interior of thehand drying chamber 2 can be viewed from above thehand drying chamber 2. Thus, a degree to which the hands are dried is easily visible. -
FIG. 11 is a transverse cross-sectional view of a hand dryer according to a second embodiment. As shown inFIG. 5 , thesecond wall section 3 of thehand dryer 81 according to the first embodiment is plate-shaped. However, as shown inFIG. 11 , asecond wall section 3 a of ahand dryer 82 according to the second embodiment has a hollow box-shaped structure including aninner surface 5 a to increase strength. -
FIG. 12 is a transverse cross-sectional view of a hand dryer according to a third embodiment. Theinner surface 5 of thesecond wall section 3 according to the first embodiment and theinner surface 5 a of thesecond wall section 3 a according to the second embodiment are planar. However, as shown inFIG. 12 , aninner surface 5 b of asecond wall section 3 b of ahand dryer 83 according to the third embodiment has a concave horizontal cross-section. The concaveinner surface 5 b according to the third embodiment allows airflows that have come into contact with the hands and include water droplets to flow from thelateral opening sections 10 toward thefirst wall section 4 side. Therefore, exposure of the user to the airflows and the water droplets can be further reduced.FIG. 18 is a transverse cross-sectional view of a modified example of the hand dryer according to the third embodiment. Theinner surface 5 b of thesecond wall section 3 b of thehand dryer 83 according to the third embodiment has a concave horizontal cross-section. However, as shown inFIG. 18 , both side portions of thesecond wall section 3 b can be bent roughly at a right angle towards thefirst wall section 4 side. Even with this structure, a similar effect as that achieved by the above concave surface can be achieved. Moreover, as a result of the bent portions, water droplets attached to theinner surface 5 b can be prevented from splashing outside from thelateral opening sections 10. -
FIG. 13 is a transverse cross-sectional view of a hand dryer according to a fourth embodiment. As shown inFIG. 13 , aninner surface 5 c of asecond wall section 3 c of ahand dryer 84 according to the fourth embodiment is a convex surface. The convexinner surface 5 c according to the fourth embodiment allows airflows that have come into contact with the hands and include water droplets to flow from thelateral opening sections 10 towards the front side. Therefore, a wall surface on which thehand dryer 84 is set can be prevented from becoming soiled by the water droplets splashing onto the wall surface. -
FIG. 14 is a side view of a hand dryer according to a fifth embodiment. As shown inFIG. 14 , aninner surface 5 d of asecond wall section 3 d of ahand dryer 85 according to the fifth embodiment is formed such that an upper portion is curved to the rear side (to thefirst wall section 4 side). Theinner surface 5 d according to the fifth embodiment of which the upper portion is curved towards the rear side directs a flow of air flowing upwards from thehand insertion opening 9 of thehand drying chamber 2 in a direction away from the user, preventing the user from being exposed to the flowing air and water droplets. -
FIG. 15 is a side view of a hand dryer according to a sixth embodiment. As shown inFIG. 15 , aninner surface 5 e of asecond wall section 3 e of ahand dryer 86 according to the sixth embodiment is formed such that an upper portion is curved towards the front side (user side). Theinner surface 5 e according to the sixth embodiment of which the upper portion is curved towards the front side widens thehand insertion opening 9 of thehand drying chamber 2, allowing the user to more easily insert the hands into thehand drying chamber 2, whereby usability is enhanced. -
FIG. 16 is a side view of a hand dryer according to a seventh embodiment. In the hand dryers according to the first embodiment to the sixth embodiment, the inner surface of the second wall section is tilted forwards to be roughly parallel with theair nozzle sections 13 to facilitate insertion of the hands and prevent water droplets from splashing onto the user. As shown inFIG. 16 , in ahand dryer 87 according to the seventh embodiment, a forward-tilt angle of aninner surface 5 f of asecond wall section 3 f is made smaller than a forward-tilt angle of theair nozzle section 13, and a distance between theinner surface 5 f of thesecond wall section 3 f and theair nozzle sections 13 is short at an upper portion and wide at a lower portion. Therefore, airflows that have come into contact with the hands and include water droplets come into contact with theinner surface 5 f of thesecond wall section 3 f according to the seventh embodiment obliquely downward. Thus, airflows flowing from thehand insertion opening 9 can be suppressed. Accordingly, the user can be prevented from being exposed to flowing air and water droplets. -
FIG. 17 is a side view of a hand dryer according to an eight embodiment. As shown inFIG. 17 , in ahand dryer 88 according to the eighth embodiment, a forward-tilt angle of aninner surface 5 g of asecond wall section 3 g is greater than a forward-tilt angle of theair nozzle section 13, and a distance between theinner surface 5 g of thesecond wall section 3 g and theair nozzle sections 13 is wide at an upper portion and short at a lower portion. In thehand dryer 88 according to the eighth embodiment, the width of thehand insertion opening 9 of thehand drying chamber 2 is widened, allowing the user to more easily insert his hands into thehand drying chamber 2, whereby usability is enhanced. - In the first to eight embodiments of the present invention, the
hand insertion opening 9 is provided in the upper portion of thehand drying chamber 2, thefirst wall section 4 is provided at the rear portion of thehand drying chamber 2, each of thesecond wall sections 3 to 3 g is provided at the front portion of thehand drying chamber 2, and a pair of theair nozzle sections 13 extends in the vertical direction on thefirst wall section 4 side. However, the hand dryer according to the present invention is not limited thereto, and a pair of the air nozzle sections can be provided on thesecond wall section 3 instead of on thefirst wall section 4. - Moreover, the
hand insertion opening 9 can be provided in the front portion of thehand drying chamber 2, thefirst wall section 4 can be provided at the upper portion of thehand drying chamber 2, thesecond wall section 3 can be provided at the lower portion of thehand drying chamber 2, and a pair of the air nozzle sections can be provided to extend in the vertical direction on any one of thefirst wall section 4 side and thesecond wall section 3 side. Furthermore, the lateral sides of thehand drying chamber 2 can be closed without providing thelateral opening sections 10. - As described above, the hand dryer according to the present invention can be advantageously used as a hand dryer that hygienically performs a drying process by jetting a high-speed airflow onto wet hands after being washed.
