FIG. 2 , the upright type vacuum cleaner in accordance with the present invention includes asuction nozzle 60 moving along a floor and drawing in air containing impurities such as dust, amain body 70 coupled with the suction-nozzle 60 and provided with suction means generating a suction force therein, and ahandle 80 provided at an upper part of themain body 70. - The
suction nozzle 60 includes anupper plate 61 and alower plate 62 forming an exterior thereof, and parts provided therein.Wheels 63 are provided at both sides of thelower plate 62, and aninlet 62 a (refer toFIG. 3 ) is formed on a lower surface thereof for drawing air therein. Theupper plate 61 covers thelower plate 62 so as to protect the parts provided therein. - In the mean time, an
agitator 64 is provided in thesuction nozzle 60 for scraping the impurities stuck on the floor as illustrates inFIG. 3 . - In more detail, the
agitator 64 a includes a rotary body formed in a cylindrical form, and a brush formed in a spiral form on an outer surface of therotary body 64 a for removing impurities being stuck on the floor. Thebrush 64 b comes into contact with a floor to be cleaned through theinlet 62 a. - The
agitator 61 is coupled with a rotary axis (Ms) of a motor (Not shown) provided at a lower end of themain body 70 by means of a coupling belt (V). Accordingly, the agitator is rotated together with the rotary axis when the rotary axis is rotated in accordance with an operation of the motor. - At this time, the
brush 64 b scrapes off the impurities on the floor, and the impurities scraped off by thebrush 64 b are drawn in through theinlet 62 a. - In this case, it is desirable that the rotary axis (Ms) and the
agitator 64 are provided to be parallel to each other for a smooth power transmission, and the coupling belt (V) is made of a flexible material such as a rubber. - Meanwhile, a temperature sensor (Not shown) is mounted at a side of the motor. The temperature sensor operates on a bimetal principle and automatically cuts off power supply to the motor when the motor is overheated and a temperature of the motor is raised to a temperature higher than a predetermined temperature.
- The
main body 70 is includes a motor (Not shown) for generating the suction force, and suction means such as a suction fan (Not shown) therein. Themain body 70 is rotatably provided to be able to rotate in a rear direction within a predetermined angle by arotary lever 65 provided at a rear of thesuction nozzle 60. - In other words, when a user holds the
handle 80 with a hand and pulls the main body rearward in a state of steeping on the rotary lever, themain body 70 is inclined rearward. Accordingly, the user can adjust the angle of themain body 70 to be suitable for the height of the user by manipulating therotary lever 65 when the user cleans the floor. - An
electric wire reel 71 is provided at a rear surface of themain body 70 for winding the electric wire thereon. It is desirable that a couple of theelectric wire reels 71 are provided respectively at an upper rear part and a lower rear part of themain body 70 to be symmetric to each other. - In the mean time, a lamp (L) is provided at a front end of the
main body 70 for lightening the front of the vacuum cleaner, and anexhaust cover 70 a is provided at an upper part of the lamp (L) through which the air being discharged to an outside thereof is passed finally. - An exhaust filter (Not shown) is provided in the
exhaust cover 70 a. The exhaust filter filters the air to be discharged to the outside (Interior space) and discharges refreshed air. A motor (Not shown) is located at a rear of the exhaust filter for providing a driving force for drawing air. - Meanwhile, a
dust collector assembly 100 is provided in a front center of themain body 70 for filtering the impurities contained in the air drawn in through thesuction nozzle 60. - The
dust collector assembly 100 filters impurities by using a cyclone using centrifugal force, or a separate filter. The dust collector assembly can of course filter impurities by using both the cyclone and the filter at the same time. - The
dust collector assembly 100 includes adust collector 110 formed in a cylindrical form for drawing air therein, the air drawn in by thesuction nozzle 60, afilter 152, and alower cover 180 as illustrated inFIG. 4 . - The
dust collector 110 is detachably provided at themain body 70. In more detail, thedust collector 110 is detachably provided at the dustcollector mounting member 72. Acoupling loop 79 is formed at themain body 70, and a coupling groove the coupling loop is coupled thereto is formed at thedust collector 110. A dust collector handle 130 is provided at an outer surface of thedust collector 110. - Accordingly, the
dust collector 110 is easily separated from thedust collector 110 when the user separates thecoupling loop 78 from thecoupling groove 79 and pulls thedust collector handle 130. - The abovementioned process is of course inversely performed when the
dust collector 110 is coupled to the dustcollector mounting member 72. - Meanwhile, an
inflow tube 74 is formed at the dustcollector mounting member 72. A first end of theinflow tube 74 is coupled with thedust collector 110, and a second end thereof is coupled with theinlet 62 a of thesuction nozzle 60. Therefore, the air drawn in by thesuction nozzle 60 is guided into thedust collector 110 along theinflow tube 74. - An
outflow tube 76 is formed at a lower surface of the dustcollector mounting member 72. Theoutflow tube 76 guides the air being discharged form thedust collector 110 to an outside (Room). In this case, the air flowed along theoutflow tube 76 is discharged to the outside thorough the exhaust filter and theexhaust cover 70 a. - Hereinafter, each component of the dust collector assembly is described in more detail referring to the accompanying drawings.
-
FIG. 5 illustrates a disassembled perspective view showing the dust collector assembly in accordance with a first embodiment of the present invention,FIG. 6 illustrates a cross-sectional view showing the dust collector in accordance with the first embodiment of the present invention, andFIG. 7 illustrates a cross-sectional view showing a lower cover of the dust collector assembly in accordance with the first embodiment of the present invention. - As illustrated in FIGS. 5 to 7, a
suction pipe 112 is provided on an outer surface ofthee dust collector 110 for guiding the air drawn in by thesuction nozzle 60 into thedust collector 110. - The
suction pipe 112 is provided in a tangential direction such that the air drawn into thedust collector 110 spirally flows along an inner wall of thedust collector 110. - A
separation plate 120 is provided at thedust collector 110 for dividing an inner space into an upper inner space and a lower inner space. Theseparation plate 120 plays a role of dividing the impurities contained in the air drawn into thedust collector 110 according to masses. - In more detail, the impurities with relatively large masses drawn into the
dust collector 110 drop down toward the lower inner space of thedust collector 110 by gravity. In this case, a pass throughhole 120 a is formed on a circumference of theseparate plate 120 for communicating with both the upper inner space and the lower inner space of thedust collector 110 such that impurities with large masses pass therethrough. - Accordingly, impurities with large masses drop down toward the lower inner space of the
dust collector 110, pass through the pass throughhole 120 a, and accumulate in the lower inner space of thedust collector 110. In the end, small mass of impurities accumulates in the upper inner space of thedust collector 110 that is divided by theseparation plate 120, and impurities with large masses accumulate in the lower inner space thereof. - Meanwhile, the
filter 152 is provided in the upper inner space of thedust collector 110 that is divided by the separation plate so as to filter the air drawn into thedust collector 110. It is desirable that thefilter 152 includes a pleated-surface filter that enlarges an area in contact with air to the utmost. - The
filter 152 is made of a material having stiffness more than predetermined stiffness with due regard to strong airflow so as to maintain the form during washing. - An
opening 142 is provided on an upper surface of thedust collector 110. Theopening 142 has a same form as a section of thefilter 152 so as to insert the filter therein. In other words, when the filter has a round section, the opening is also formed in a round form. - In this case, the
filter 152 is detachably provided at theopening 152. For this, acoupling rib 156 is provided on an upper surface of thefilter 152, and acoupling lever 148 coupled with thecoupling rib 156 is rotatably provided at one side of theopening 142. - In more detail, an upper
end fixing member 157 is formed on the upper surface of thefilter 152, and thecoupling rib 156 is formed at one side of the upperend fixing member 157. A downwardly recessedloading portion 146 is formed at one side of theopening 142 and thecoupling lever 146 is rotatably provided at the downwardly recessedloading portion 146. - The upper
end fixing member 156 is fastened to the circumference of theopening 142, and thecoupling lever 148 is rotated on alever hinge 149 at one side thereof and coupled with thecoupling rib 156 so as to fix the filter to theopening 142. - A
filter handle 158 is provided at the upperend fixing member 156 for the user to easily hold thefilter 150. It is desirable that a couple of the filter handles 158 are formed on the upper surface of the upperend fixing member 156. - In the mean time, the
lower cover 180 selectively opens/closes a lower surface of thedust collector 110. For this, as illustrated inFIGS. 6 and 7 , a first end of thelower cover 180 is rotatably coupled with thedust collector 110 by thecover hinge 182, and a second end thereof is detachably coupled with thedust collector 110. - In this case, the coupling means 190 includes a
projection 192 formed at thelower cover 180, ahook 194 coupled with theprojection 192, and asupport 196 formed on an outer surface of thedust collector 110. - The
hook 192 includes afirst coupling member 194 a and asecond coupling member 194 b, and coupled with thesupport 196 by thehinge axis 198. Accordingly, when the user presses thefirst coupling member 194 a, the first andsecond coupling members hinge axis 198. - A compression spring (S) is provided between the
first coupling member 194 a and thedust collector 110. The compression spring (S) returns the first andsecond coupling members first coupling member 194 a is removed. It is obvious that theprojection 192 is formed at thedust collector 110, and thesupport 196 and thehook 194 are formed at thelower cover 180. - The
lower cover 180 includes ananti-rotation plate 185 as illustrated inFIG. 7 . Theanti-rotation plate 185 supports a lower surface of theseparation plate 120. Theanti-rotation plate 185 blocks a convection current and prevents the impurities accumulated in the lower inner space of thedust collector 110 from scattering. - In the mean time, as illustrated
FIG. 6 , thefilter 152 filters the air drawn into thedust collector 110 and guides the air to the lower inner space of thedust collector 110, and thelower cover 180 discharges the air guided by thefilter 152 toward the lower portion of thedust collector 110. - For this, a
first discharge tube 152 a is provided in thefilter 152 for guiding the filtered air toward the lower inner space of thedust collector 110, and asecond discharge tube 178 passing thorough theseparation plate 120 and communicating with thefirst discharge tube 152 a is provided at thelower cover 180. - In this case, it is desirable that an inside diameter of the
second discharge tube 178 is same as that of thefirst discharge tube 152 a, and thesecond discharge tube 178 and thelower cover 180 are formed as a single body. - A
discharge tube cover 178 a is detachably provided on an upper surface of thesecond discharge tube 178. Thedischarge tube cover 178 a is made of a flexible material such as rubber, and is radially incised a plurality of times. - The
outflow cover 178 a prevents the impurities stuck on thefilter 152 and the impurities accumulated up in the upper inner space of thedust collector 110 from being flowed into thesecond discharge tube 178 when thefilter 152 is separated from theopening 142 of thedust collector 110. Thesecond discharge tube 178 communicates with an outflow tube 76 (Refer toFIG. 4 ) formed at the dustcollector mounting member 72. - In the mean time, a
liquid sprayer 160 is provided on an inner surface of thedust collector 110 for preventing static electricity. Theliquid sprayer 160 includes abody 162 formed in a cylindrical form and having liquid therein, aspray button 164 provided at an upper end of thebody 162, and aninjection pipe 166 extended from thebody 162 toward thefilter 152. In this case, thespray button 164 is passed though the upper surface of thedust collector 110 and is projected to the outside thereof. - Accordingly, when the user presses the
spray button 164, the liquid stored in thebody 162 is raised along a passage (Not shown) therein and sprayed through theinjection pipe 166. - In this case, water is normally used for the liquid, and the liquid has an insecticide or germicide aromatic agent, or the like added thereto.

FIG. 8 illustrates a disassembled perspective view showing a dust collector assembly in accordance with a second embodiment of the second embodiment of the present invention,FIG. 9 illustrates a cross-sectional view showing the dust collector assembly in accordance with the second embodiment of the present invention,FIG. 10 illustrates a cross-sectional view showing an opened state of the lower cover of the dust collector in accordance with the second embodiment of the present invention, andFIG. 11 illustrates a perspective view showing an inner structure of the dust collector in accordance with the second embodiment of the present invention. - As illustrated in FIGS. 8 to 10, the dust collector assembly in accordance with the second embodiment of the present invention includes a
dust collector 110, a filter 52, and alower cover 180. - In this case, an outside diameter of the
separation plate 220 is formed to be smaller that the inside diameter of thedust collector 110. Accordingly, agap 220 a is formed between theseparation plate 220 and thedust collector 110. Thegap 220 a plays the same role as the pass throughhole 120 a. In other words, impurities with large masses among the impurities drawn into thedust collector 110 are accumulated in the lower inner space of thedust collector 110. - It is desirable that the
separation plate 220 and thelower cover 180 are formed as a single body. In this case, as illustrated inFIG. 10 , theseparation plate 220 rotates together with the lower cover 1880 and escapes to the outside of thedust collector 110 when the lower surface of thedust collector 110 is opened. At this time, for preventing theseparation plate 220 from being in contact with the inner surface of thedust collector 110, the outside diameter of theseparation plate 220 is formed to be smaller enough than the inside diameter of thedust collector 110. Theseparation plate 220 may of course be detachably coupled with thelower cover 180. - A
second discharge tube 178 for discharging the air guided by thefilter 152 toward a bottom of thedust collector 110 is provided between theseparation plate 220 and thelower cover 180. In this instance, theseparation plate 220 is formed as a single body with thesecond discharge tube 178, or detachably coupled with an upper surface of thesecond discharge tube 178. - As illustrate in
FIG. 11 , adischarge tube cover 178 a is provided on the upper surface of thesecond discharge tube 178. Thedischarge tube cover 178 a has a same structure as that in the aforementioned first embodiment. - Hereinafter, the operation of the vacuum cleaner in accordance with the present invention will be described as follows.
- First, when the vacuum cleaner is operated, a suction force is transmitted to a
suction nozzle 60 by the operation of a motor (Not shown) built in thebody 70. Accordingly, air with impurities is drawn in through aninlet 62 a of thesuction nozzle 60. - The air is flowed into the
dust collector 110 through aninflow tube 74 coupled with theinlet 62 a and asuction pipe 112 formed on an outer surface of the dust collector. - In this case, impurities with large masses among the impurities contained in the air are accumulated in the lower inner space of the
dust collector 120 through the pass throughhole 120 a or thegap 220 a, and the impurities with relatively small masses are filtered while being entered into thefilter 152, and accumulated in the upper inner space of thedust collector 110. Therefore, the impurities with large masses are accumulated on the upper surface of alower cover 180 and the impurities with a small mass on an upper surface of theseparation plate - The air passed through the
filter 150 is discharged toward a bottom of thedust collector 100 along thefirst discharge tube 152 a and thesecond discharge tube 178. The air is then discharged to the outside through the exhaust filter and theexhaust cover 70 a after being passed through a motor (Not shown) along theoutflow tube 76 formed at themain body 70. - In the mean time, when the vacuum cleaner is operated for a predetermined time and the large amount of impurities are accumulated in the
dust collector 110, a user opens a lower surface of thedust collector 110 for cleaning the inside of thedust collector 110. - Hereinafter, a process of opening the lower surface of the
dust collector 110 is as follows. First, as illustrated inFIGS. 7 and 10 , when the user presses thefirst coupling member 194 a of thehook 194, thesecond coupling member 194 b is rotated around thehinge 198 and separated from theprojection 192. Accordingly, thelower cover 180 is rotated around thecover hinge 182 so as to open the lower surface of thedust collector 110. - When the
lower cover 180 is opened, the user can easily remove the impurities accumulated in the lower inner space, i.e., on the upper surface of thelower cover 180. - In this case, as illustrated in
FIG. 10 , when theseparation plate 220 having an outside diameter smaller than an inside diameter of thedust collector 110 is formed as a single body with alower cover 180, or fixed to thesecond discharge tube 178, theseparation plate 220 rotates together with thelower cover 180 and escapes to an outside of thedust collector 110. Accordingly, the user can remove not only the impurities accumulated on the upper surface of thelower cover 180 but also the impurities accumulated on the upper surface of theseparation plate 220. - When the user releases pressure on the
first coupling member 194 a, thefirst coupling member 194 a and thesecond coupling member 194 b are returned to original places by the compression spring (S). - A process of coupling the
lower cover 180 with thedust collector 110 is described as follows. First, when thelower cover 180 is lifted upward, thelower cover 180 rotates around the axis of thecover hinge 182 and closely adhered to thedust collector 110. In this instance, the user needs to continuously presses thelower cover 180 upwardly with a stronger power than elasticity of the compression spring (S) such that theprojection 192 is coupled with thesecond coupling member 194 b of thehook 194. - As aforementioned, when the
projection 192 is coupled with thesecond coupling member 194 b of thehook 194, the lower cover 186 closes the lower surface of thedust collector 110. - In the mean time, the
filter 152 has been supposed as a pleated-surface filter. However, thefilter 152 may include a net filter, or a filter in a form of a combination net filter and the pleated-surface filter. - Instead of the pleated-surface filter, the
filter 152 may be formed not only in a form wherein the net filter is coupled with a sponge, but also in a form wherein a plurality of the pleated-surface filers or the net filters are overlapped. - Although the
filter 152 is mounted at anopening 142 formed on the upper surface of thedust collector 110 in the abovementioned embodiment, thefilter 152 may be mounted on the upper surface of theseparation plate 120. A separate structure for fixing the filter may be installed in thedust collector 110. -
FIG. 12 illustrates a disassembled perspective view showing a canister type vacuum cleaner in accordance with the present invention. As illustrated inFIG. 12 , the canister type vacuum cleaner in accordance with the present invention includes asuction nozzle 310, amain body 300 coupled with thesuction nozzle 310 and having suction means for generating a suction force therein, and adust collector assembly 100. - The
main body 300 includes alower body 300 a having suction means, and anupper body 300 b for protecting the suction means built in thelower body 300 a and collecting electric parts (Not shown) controlling the vacuum cleaner. - A dust
collector mounting member 302 having thedust collector 110 inserted and fixed thereto is formed between the lowermain body 300 a and the uppermain body 300 b. The dustcollector mounting member 302 is formed in a size corresponding to thedust collector 110, and anoutflow tube 302 a is formed on a lower surface thereof for guiding air discharged from the lower surface of thedust collector 110. - A coupling button 304 is provided at the
upper body 300 b for coupling the dust collector with themain body 300. The coupling button 304 is coupled with acoupling groove 79 formed on an upper surface of thedust collector 110 and secures thedust collector 110 to the main body. The coupling button 304 performs the same role as thecoupling rib 78 formed at themain body 70 of the aforementioned upright type vacuum cleaner. - Meanwhile, wheels (W) are provided on both rear sides of the
lower body 300 a so as to smoothly move themain body 300 on a floor. Anoutlet 306 is formed on the wheels (W) for discharging the air filtered by passing through the filter of thedust collector assembly 100. Theoutlet 306 is communicated with theoutflow tube 302 a. Asuction hose 320, an operatingmember 330, andn extension tube 340 are provided between themain body 300 and thesuction nozzle 310. - In this case, the
suction nozzle 320 is coupled with acoupling tube 360. Thecoupling tube 360 is communicated with thesuction pipe 112 formed on the outer surface of thedust collector 110. - On a rear surface of the
main body 300, apower cord 350 is provided for supplying power source to the suction means received in themain body 300. - The operation of the canister type vacuum cleaner in accordance with the present invention is described as follows. First, when the power source is supplied to the suction means received in the
main body 300 through thepower cord 350 provided on a rear surface of themain body 300, the vacuum cleaner is in a standby mode, and when the user operates a button of the operatingmember 330, a suction force is generated by the suction means built in themain body 300. - In this instance, the suction force is transmitted to the
suction nozzle 310 through thesuction hose 320 and theextension tube 340 coupled with thecoupling tube 360 of theman body 300. Accordingly, the impurities such as dust or shag are drawn into the main body together with air through thesuction nozzle 310 and accumulated at thedust collector assembly 100. The air from which the impurities are removed is discharged to an outside thereof through theoutflow tube 302 a and a dischargingmember 306 formed at thelower body 300 a. - When the process is repeated, impurities are accumulated at the
dust collector assembly 100. Accordingly, after a predetermined period of time of using the vacuum cleaner, thedust collector assembly 100 is separated from the dustcollector mounting member 302 and the impurities therein are removed. - The process of removing the impurities accumulated at the dust collector assembly is described in the embodiment of the upright type vacuum cleaner and will be omitted hereinafter.
- The vacuum cleaner in accordance with the present invention has following effect. First, since the vacuum cleaner in accordance with the present invention has a filter detachably provided at the dust collector, it is easy to clean and replace the filter.
- Second, since the vacuum cleaner in accordance with the present invention has a sprayer provided on an inner surface of the dust collector, humidity in the dust collector is constantly maintained. Therefore, static electricity generated when the filter is separated from the dust collector is prevented from generating.
- Third, the vacuum cleaner in accordance with the present invention enables to maximize work efficiency because an appropriate filter such as pleated-surface filter and a net filter is selectively used according to the kind of impurities.
- Fourth, the vacuum cleaner in accordance with the present invention enables selectively opening and closing a lower surface of the dust collector by a lower cover, and therefore it is easy to remove impurities accumulated in the dust collector.
- When a separation plate is formed as a single body with the lower cover, the separation plate is separated from the dust collector together with the lower cover. In this case, the impurities accumulated on the upper surface of the lower cover as well as the impurities accumulated on the upper surface of the separation plate are removed together.
- It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
