Definitions
- the present invention relates to a dust collector of a vacuum cleaner, and more particularly, to a dust collector of a vacuum cleaner according the preamble portion of claim 1 that has an increased dust collection capacity.
- a vacuum cleaner is a device that can suction air containing dust using the vacuum pressure generated by a vacuum motor mounted in a main body and filter off the dust in the main body.
- Such a vacuum cleaner includes a suction nozzle for suctioning air containing dust, a main body of the vacuum cleaner that communicates with the suction nozzle, an extension tube for guiding the air suctioned through the suction nozzle to the main body, and a connecting passage for connecting the air that passes through the extension tube to the main body.
- the suction nozzle forms a nozzle suction opening of a predetermined size on a bottom thereof, for suctioning air containing dust collected on the floor.
- a drive unit that generates suctioning force to suction outside air including dust through the suctioning nozzle.
- a dust collector for separating and storing dust is detachably installed in the main body.
- the dust collector separates and stores dust in air that is suctioned through the suction nozzle.
- the dust collector includes a dust collection body, an inlet through which air is suctioned into the dust collection body, a cyclone unit separating dust from air suctioned into the dust collection body, a dust storage part storing the dust separated in the cyclone unit, and an outlet through which the purified air is discharged.

- the dust collector of a related art when more than a predetermined amount of dust are stored in the dust collector while the vacuum cleaner is operating, the dust circulates and rises along an inner wall of the dust collector to invade the cyclone unit formed in an upper space of the dust collection body. Thus, the non-separated dust is discharged together with the air current through the outlet, thus lowering the dust collecting effectiveness of the dust collector.
- the dust settles down on the bottom of the dust collection body and has a low density.
- the dust inside the dust collection body takes up excessive volume in proportion to its weight, necessitating frequent (and therefore, cumbersome) emptying of the dust collection body in order to maintain a level of dust collecting effectiveness.
- JP 58-175532 which has been used to form the preamble portion of claim 1, discloses a dust collector for a vacuum cleaner which has a fixed first plate provided in a dust container and a second plate supported in the dust container so as to be pivotable bi-directionally from one side of the fixed plate to the opposite side of the fixed plate, thereby compressing dust collected in the dust container between the plates.
- the second plate is manually operable by means of a crank handle removably insertable from the outside of the vacuum cleaner into a receptacle of the axis of the second plate of the dust collector placed inside the vacuum cleaner.
- the present invention is directed to a dust collector of a vacuum cleaner that substantially obviates one or more problems due to limitations and disadvantages of the related art.

Abstract
Description
- The present invention relates to a dust collector of a vacuum cleaner, and more particularly, to a dust collector of a vacuum cleaner according the preamble portion of claim 1 that has an increased dust collection capacity.
- Generally, a vacuum cleaner is a device that can suction air containing dust using the vacuum pressure generated by a vacuum motor mounted in a main body and filter off the dust in the main body.
- Such a vacuum cleaner includes a suction nozzle for suctioning air containing dust, a main body of the vacuum cleaner that communicates with the suction nozzle, an extension tube for guiding the air suctioned through the suction nozzle to the main body, and a connecting passage for connecting the air that passes through the extension tube to the main body.
- Here, the suction nozzle forms a nozzle suction opening of a predetermined size on a bottom thereof, for suctioning air containing dust collected on the floor.
- Within the main body of the vacuum cleaner is a drive unit that generates suctioning force to suction outside air including dust through the suctioning nozzle.
- Also, a dust collector for separating and storing dust is detachably installed in the main body. The dust collector separates and stores dust in air that is suctioned through the suction nozzle.
- In detail, the dust collector includes a dust collection body, an inlet through which air is suctioned into the dust collection body, a cyclone unit separating dust from air suctioned into the dust collection body, a dust storage part storing the dust separated in the cyclone unit, and an outlet through which the purified air is discharged.
- Meanwhile, the dust stored at the bottom of the dust collection body (that is, the dust in the dust storage part) is continuously circulated along an inner circumference of the dust collection body by means of a circulating current within the dust collection body while the vacuum cleaner is operating.
- When the operation of the vacuum cleaner ends, the dust settles down on the floor of the dust collection body and is stored therein at a low density.
- Therefore, in the dust collector of a related art, when more than a predetermined amount of dust are stored in the dust collector while the vacuum cleaner is operating, the dust circulates and rises along an inner wall of the dust collector to invade the cyclone unit formed in an upper space of the dust collection body. Thus, the non-separated dust is discharged together with the air current through the outlet, thus lowering the dust collecting effectiveness of the dust collector.
- As described above, when the operation of the vacuum cleaner ends, the dust settles down on the bottom of the dust collection body and has a low density. In other words, the dust inside the dust collection body takes up excessive volume in proportion to its weight, necessitating frequent (and therefore, cumbersome) emptying of the dust collection body in order to maintain a level of dust collecting effectiveness.
- Accordingly, in order to improve the convenience in using the vacuum cleaner, constant efforts are being made to develop a product that can maximize the amount of dust collected in the dust collection body while improving the dust collecting effectiveness.
-
JP 58-175532 - Accordingly, the present invention is directed to a dust collector of a vacuum cleaner that substantially obviates one or more problems due to limitations and disadvantages of the related art.
- An object of the present invention is to provide a dust collector of a vacuum cleaner that has an increased dust collection capacity.
- An aspect of the present invention is to provide a dust collector of a vacuum cleaner that has an increased dust collection capacity by automatically compressing dust stored therein.
- Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Fig. 1 is a perspective view illustrating a dust collector separated from a vacuum cleaner according to an embodiment of the present invention. - Referring to
Fig. 1 , the vacuum cleaner according to an embodiment of the present invention includes amain body 100 of the vacuum cleaner having a suction generator therein and adust collector 200 separating and storing dust in the suctioned air. - The vacuum cleaner further includes a suction nozzle (not shown) suctioning air containing dust and a connecting passage (not shown) connecting the suction nozzle to the
main body 100. - In the present invention, the suction nozzle and the connecting passage have a basic constitution that is the same as the related art, and thus detailed descriptions thereof will be not given.
- In detail, a
main body inlet 110 is formed at a front, lower portion of themain body 100. Air containing dust is suctioned from the suction nozzle through themain body inlet 110. - A
main body outlet 120 is formed on a side of themain body 100. Air separated from dust is discharged out of themain body 100 through themain body outlet 120. - The
dust collector 200 includes adust separator 210 for separating dust from suctioned air and adust container 220 for storing the dust separated in thedust separator 210. - The
dust separator 210 includes a cyclone unit 211 (refer toFig. 3 ) separating dust from the suctioned air using a difference in centrifugal force between air and dust (a cyclone principle). - The
dust collector 200 is configured to maximize its ability to store dust inside. For this reason, thedust collector 200 further includes a structure for reducing the volume of dust stored inside thedust container 220. - Below, a vacuum cleaner having a dust collector that maximizes its ability to store dust therein according to the present invention will be described with reference to
Figs. 2 to 5 . -
Fig. 2 is a perspective view illustrating the dust collector separated from a dust collector receiving part applied to the vacuum cleaner.Fig. 3 is a sectional perspective view of the dust collector.Fig. 4 is an enlarged view of section "A" inFig. 3 .Fig. 5 is a perspective view illustrating a coupling relation between a driving apparatus for compressing dust stored in the dust collector and the dust collector. - Referring to
Figs. 2 to 5 , thedust collector 200 according to an embodiment of the present invention is detachably installed on themain body 100. - The
main body 100 includes a dustcollector receiving part 130 for receiving thedust collector 200. - A pair of
press members dust collector 200, for decreasing the volume of the dust stored in thedust container 220 to increase the dust collection capacity. - The pair of
press members dust container 220 can be increased, thereby increasing the maximum dust collection capacity in thedust container 220. - Hereinafter, the pair of
press members first press member 310 and thesecond press member 320, respectively, for the sake of descriptive simplicity. - In the present embodiment, at least one of the pair of
press members dust container 220 to compress the dust stored between the pair ofpress members - In other words, when both of the first and
second press members dust container 220, the first andsecond press members first press member 310 and the one side of thesecond press member 320 facing the one side of thefirst press member 310 becomes narrower, thus compressing the dust stored between the first andsecond press members - However, in the present embodiment, the
first press member 310 is rotatably disposed within thedust container 220 and thesecond press member 320 is fixed within thedust container 220. - That is, the
first press member 310 serves as a rotating member and thesecond press member 320 serves as a fixed member. - A
dust storage part 221 is formed within thedust container 220 to form a space for storing dust. Thedust storage part 221 is formed so as to enclose a curve traced by afree edge 311 of thefirst press member 310 as it rotates within thedust storage part 221. - The
second press member 320 may be disposed between an inner circumferential surface of thedust storage part 221 and arotating shaft 312 serving as a rotation center of thefirst press member 310. - In other words, the
second press member 320 is disposed on a plane connecting therotating shaft 312 with the inner circumferential surface of thedust storage part 221. Here, thesecond press member 320 entirely or partially blocks a space defined between the inner circumferential surface of thedust storage part 221 and the axis of therotating shaft 312, so as to compress the dust together with thefirst press member 310 when the dust is pushed by thefirst press member 310. - For this purpose, an
end 321 of thesecond press member 320 may be integrally formed on the inner circumferential surface of thedust storage part 221, and the other end may be integrally formed with astationary shaft 322 coaxially provided with therotating shaft 312 of thefirst press member 310. - Only the
end 321 of thesecond press member 320 may be integrally formed with the inner circumferential surface of thedust storage part 221, or only the other end of thesecond press member 320 may be integrally formed with thestationary shaft 322. In other words, thesecond press member 320 is fixed to at least one of the inner circumferential surface of thedust storage part 221 and thestationary shaft 322. - However, although the
end 321 of thesecond press member 320 is not integrally formed with the inner circumferential surface of thedust storage part 221, theend 321 of thesecond press member 320 may be disposed proximally to the inner circumferential surface of thedust storage part 221. - Also, although the other end of the
second press member 320 is not integrally formed with thestationary shaft 322, the other end of thesecond press member 320 may be disposed proximally to thestationary shaft 322. - The reason for the above is to minimize the amount of the dust that is pushed by the
first press member 310 to leak through gaps formed at a lateral side of thesecond press member 320. - The above-structured first and
second press members rotating shaft 312 of thefirst press member 310 may be disposed on the same axis as the center of thedust storage part 221. - The
stationary shaft 322 may protrude inward from one end of thedust storage part 221. A cavity is formed in an axial direction within thestationary shaft 322 to assemble therotating shaft 312. A predetermined portion of therotating shaft 312 is inserted into the cavity from topside of thestationary shaft 322. - Furthermore, the vacuum cleaner according to the present invention includes a
driving apparatus 400 selectively connected to therotating shaft 312 of thefirst press member 310 to rotate thefirst press member 310. - Hereinafter, a coupling relation between the
dust collector 200 and thedriving apparatus 400 will now be described with reference toFigs. 4 and5 . - The driving
apparatus 400 includes a drivingmotor 430 for generating driving force and drivingmechanisms motor 430 to thefirst press member 310. - In detail, the driving
mechanisms rotating shaft 312 of thefirst press member 310 and a driving gear transferring driving force to the drivengear 410. - The
driving gear 420 is coupled to a rotating shaft of the drivingmotor 430, and rotates by the drivingmotor 430. - Therefore, when the driving
motor 430 rotates, thedriving gear 420 coupled to the drivingmotor 430 rotates, and rotating force of the drivingmotor 430 is transferred to the drivengear 410 through thedriving gear 420, thereby rotating the drivengear 410 to rotate thefirst press member 310. - Here, the driving
motor 430 is disposed under the dustcollector receiving part 130, and thedriving gear 420 is coupled to a rotating shaft of the drivingmotor 430 and disposed on the bottom surface of the dustcollector receiving part 130. - An outer circumferential surface of the
driving gear 420 is partially exposed from the bottom of the dustcollector receiving part 130 to the outside. For this purpose, a motor receiving portion (not shown) for installing the drivingmotor 430 may be formed under the bottom of the dustcollector receiving part 130. Anopening 131 is formed at the approximate center of the bottom of the dustcollector receiving part 130, for partially exposing the outer circumferential surface of thedriving gear 420. - Meanwhile, the
rotating shaft 312 of thefirst press member 310 is inserted into the cavity of thestationary shaft 322 from a top portion of thestationary shaft 322, and the drivengear 410 is inserted into the cavity of thestationary shaft 322 from a lower end of thedust container 220 and coupled to therotating shaft 312. - Also, a width-
difference portion 312c is formed in therotating shaft 312 and supported by an upper end of thestationary shaft 322. The width-difference portion 312c divides therotating shaft 312 into anupper shaft 312a coupled to thefirst press member 310 and alower shaft 312b coupled to the drivengear 410. - The
lower shaft 312b includes agroove 312d for receiving a gear shaft of the drivengear 410, so that thelower shaft 312b is coupled to the drivengear 410. - The
groove 312d may be formed of various shapes such as a circular shape and a rectangular shape, and the gear shaft of the drivengear 410 is formed of a shape engaged with thegroove 312d. - Therefore, when the driven
gear 410 is coupled to therotating shaft 312, the drivengear 410 is exposed to the outside of thedust container 220. - Since the driven
gear 410 is exposed to the outside of thedust container 220, when thedust collector 200 installed on the dustcollector receiving part 130, the drivengear 410 is engaged with thedriving gear 420. - The driving
motor 430 may be a motor capable of both forward and reverse operation. In other words, the drivingmotor 430 is a motor capable of rotating in either direction. - The driving
motor 430 may rotate in both forward and reverse directions. In other words, the drivingmotor 430 may be a motor capable of bidirectionally rotating. - Accordingly, as illustrated in
Figs. 6 and7 , thefirst press member 310 may rotate in forward/reverse directions, and thus the compressed dust is accumulated in both sides of thesecond press member 320. - In order to allow the driving
motor 430 to rotate bidirectionally, a synchronous motor may be used as the drivingmotor 430. - The synchronous motor is configured to rotate in forward/reverse directions by itself. When a force greater than a set value is applied to the synchronous motor while rotating in one direction, the synchronous motor rotates in a reverse direction.
- Here, the force applied to the synchronous motor is torque that is generated when the
first press member 310 compresses the dust. The synchronous motor is configured to rotate in a reverse direction when the torque reaches the set value. - Since the synchronous motor is well known to those skilled in the art, detailed description thereof will not be provided. It is worth stating, however, the driving
motor 430 rotate in forward/reverse directions by means of the synchronous motor. - Even if the
first press member 310 compresses dust and reaches the limit point when it cannot rotate any more, thefirst press member 310 may continuously compress the dust for a predetermined time. - Here, the limit point when the
first press member 310 cannot rotate any more means that the torque has reached the set value. - When the torque reaches the set value, driving force to rotate the
first press member 310, that is, power applied to the drivingmotor 430 is cut off for a predetermined time, maintaining the dust compressed in the state that thefirst press member 310 does not rotate. After the predetermined time elapses, power is applied to the drivingmotor 430, so that thefirst press member 310 can rotate. - The point of time of cutting off the power being applied to the driving
motor 430 is the time when the torque reaches the set value. Therefore, when the drivingmotor 430 is driven again, the rotating direction of the drivingmotor 430 will be reverse to the rotating direction before power is cut off. - The driving
motor 430 may rotate thefirst press member 310 in the forward/reverse directions at a constant angular speed, in order to more easily compress the dust. - When a quantity of dust exceeding a predetermined amount is collected inside the
dust container 220, it may be informed to a user that it is time to empty thedust container 220, in order to prevent a drop in vacuuming ability and an overloaded driving motor. - For this reason, a display unit (not shown) is provided in the
main body 100, thedust collector 200 or a handle (not shown). When the dust exceeding a predetermined amount is collected inside thedust container 220 and thus the rotation range of thefirst press member 310 falls below a predetermined angle, the display unit may notify the user that it is time to empty thedust container 220. -
Figs. 6 and7 are plan views illustrating how dust is compressed within the dust collector. - Below, a compressing procedure of the dust collected within the
dust container 220 will be described with reference toFigs. 6 and7 . - When a user performs a cleaning operation using the vacuum cleaner, the dust separated in the
cyclone unit 211 is stored in thedust storage part 221. Here, the pair ofpress members dust storage part 221. - In detail, when the driving
motor 430 rotates in one direction, rotating force of the drivingmotor 430 is transferred to the drivengear 410 through thedriving gear 420. Therefore, the drivengear 410 rotates, thereby rotating therotating shaft 312 and thefirst press member 310. - Here, since the
driving gear 420 is engaged with the drivengear 410, when the drivingmotor 430 rotates in one direction, thedriving gear 420 rotates in the same direction as the rotating direction of the drivingmotor 430, and the drivengear 410 rotates in a reverse direction to the rotating direction of the drivingmotor 430. - That is, the rotating direction of the driven
gear 410 and therotating shaft 312 are opposite to the rotating direction of the drivingmotor 430. - When the
first press member 310 rotates in the other direction (counterclockwise direction), thefirst press member 310 pushes the dust collected between the first andsecond press members second press member 320, thereby compressing the dust. Thefirst press member 310 continuously rotates until the torque generated during the compression of the dust reaches the set value. - When the torque reaches the set value, power applied to the driving
motor 430 is cut off, stopping thefirst press member 310 in the state that the dust is compressed. After a predetermined time elapses, the drivingmotor 430 is driven again, rotating thefirst press member 310. - Here, since the
first press member 310 is stopped in the state that the torque reaches the set value, the rotating direction thereof is changed to a clockwise direction, as illustrated inFig. 7 . - When the
first press member 310 rotates in a clockwise direction, thefirst press member 310 pushes the dust collected between the first andsecond press members second press member 320, thereby compressing the dust. - The compressing operation is repeatedly performed until the rotation range of the
first press member 310 falls below a predetermined angle. -
Fig. 8 is a disassembled view of a dust separator and a dust container from the dust collector andFig. 9 is a perspective view of the dust separator illustrated inFig. 8 as seen from underneath. - Referring to
Figs. 8 and9 , thedust separator 210 is coupled to an upper side of thedust container 220. The dust separated in thedust separator 210 moves downward and is stored in thedust container 220. - In detail, an
inlet 211a for suctioning air containing dust is disposed in a tangent direction of thedust separator 210 in an upper, outer circumferential surface of thedust separator 210. Acover 211d is detachably provided in a top portion of thedust separator 210. - An
outlet 211b is formed at a center portion of thecover 211d. The purified air, which is separated by the inside of the dust separator 210 (that is, the cyclone unit 211), is discharged through theoutlet 211b. - A
filter member 211c of a cavity shape is coupled to theoutlet 211b. An outer circumferential surface of thefilter member 211c has a plurality of through holes formed therein to discharge air that has undergone a dust separating process in thecyclone unit 211. - A
partition plate 230 is formed horizontally at a bottom of thedust separator 210. Thepartition plate 230 divides mutually thedust separator 210 and thedust container 220. - Furthermore, the
partition plate 230 prevents the dust stored inside thedust container 220 from scattering to thedust separator 210 when thedust separator 210 is coupled to thedust container 220. - The
partition plate 230 includes adust discharge port 231. The dust separated in thecyclone unit 211 is discharged to thedust container 220 through thedust discharge port 231. - Here, the
dust discharge port 231 may be located at the side opposite to thesecond press member 320. The reason for the above is that the quantity of the dust compressed on either side of thesecond press member 320 is maximized to minimize scattering of the dust during the process of storing the dust in thedust container 220, while at the same time, to maximize the dust collection capacity of thedust storage part 221, and to allow the dust separated in thedust separator 210 to easily fall down to thedust container 220. - The
dust separator 210 and thedust container 220 include anupper handle 212 and alower handle 223, respectively, so as to couple thedust separator 210 and thedust container 220 to each other. - Also, the
dust collector 200 includes a hook fastener such that thedust container 220 is coupled to thedust separator 210 with thedust collector 220 installed on thedust separator 210. - In detail, a
hook receptacle 241 is disposed in an outer, lower circumferential surface of thedust separator 210, and ahook 242 is disposed in an upper, outer circumferential surface of thedust container 220, and selectively coupled to thehook receptacle 241. - Meanwhile, when the
cyclone unit 211 is referred to as a main cyclone unit and thedust storage part 221 is referred to as a main storage unit, the present invention may further include at least oneauxiliary cyclone unit 140 provided in themain body 100 of the vacuum cleaner and anauxiliary storage unit 224 provided in thedust collector 200. - Here, the
auxiliary cyclone unit 140 secondarily separates dust from the air discharged from themain cyclone unit 211, and theauxiliary storage part 224 stores the dust separated by theauxiliary cyclone unit 140. - The
auxiliary storage part 224 is provided on an outer circumferential surface of thedust collector 200 with its top surface open. - In the present embodiment, the
auxiliary storage part 224 is disposed on an outer circumferential surface of thedust container 220, and anauxiliary dust entrance 213 communicating with theauxiliary storage part 224 is disposed on an outer circumferential surface of thedust separator 210. - Here, auxiliary dust entrance holes 213a that are selectively connected to dust discharge holes 141 of the
auxiliary cyclone unit 140 are formed on an outer wall of theauxiliary dust entrance 213, and a bottom surface of theauxiliary dust entrance 213 is opened to communicate with an upper side of theauxiliary storage part 224. - Accordingly, when the
main cyclone unit 211 is installed on themain body 100 of the vacuum cleaner, the auxiliarydust entrance holes 213a are connected to the dust discharge holes 141 of theauxiliary cyclone unit 140. - Thus, the dust separated in the
auxiliary cyclone unit 140 passes through the auxiliarydust entrance holes 213a to be stored in theauxiliary storage part 224. - Hereinafter, the operation of the above-structured vacuum cleaner will be described according to the present invention.
- When power is supplied to the vacuum cleaner, the suction generator generates force for suctioning air, and air containing dust is suctioned into the suction nozzle using the force.
- The air that is suctioned through the suction nozzle flows to the
inlet 211a of themain cyclone unit 211 through themain body inlet 110. The air that passes through theinlet 211a of themain cyclone unit 211 is guided along an inner wall of themain cyclone unit 211 in a tangent direction to flow a spiraling motion, and thus the dust is separated from the air due to a difference in centrifugal force between air and dust, and falls down. - The dust in the air thus spirals along the inner wall of the
main cyclone unit 211 and descends through thedust discharge port 231 of thepartition plate 230, and is stored in themain storage part 221. - The air firstly purified by means of the
main cyclone unit 211 passes through theexhaust member 211c and is discharged through theoutlet 211b. Then the air flows into theauxiliary cyclone unit 140. - Accordingly, the dust that is separated from the air using the cyclone principle within the
auxiliary cyclone unit 140 is stored in theauxiliary storage part 224, and the air purified in theauxiliary cyclone unit 140 is discharged from theauxiliary cyclone unit 140, flows into themain body 100, and is discharged from themain body 100 through themain body outlet 120. - Meanwhile, most of the dust that flows into the vacuum cleaner is stored in the
main storage part 221 during a cleaning operation. Also, since the dust stored within themain storage part 221 is compressed by the first andsecond press members main storage part 221. - The operation of the
first press member 310 and the interaction between the first andsecond press members - When a quantity of dust exceeding a predetermined amount is stored inside the
dust container 220 during a cleaning operation, a signal is generated in the display unit, and the signal may notify a user that it is time to empty thedust container 220. - Then, a user separates the
dust collector 200 from themain body 100 and empties thedust container 220. - Referring to the diagrams, a canister-type vacuum cleaner has been described above as an example of a vacuum cleaner according to the present invention. However, the present invention is not limited thereto, and may be applied to an upright-type, a robot-type, or other type of vacuum cleaner
- Also, a pair of press members have been described above, but a plurality of press members may be provided or a plurality of rotatable press members may be provided in the present embodiment.
- According to the present invention, the dust that is stored in a dust collector can be compressed and minimized in volume by means of a plurality of press members, maximizing a dust collection capacity of the dust collector.
- Since the dust collection capacity of the dust collector is maximized by the compressing operation of a plurality of press members, a user does not have to frequently empty the dust collector.
- Since the dust collected in the dust collector is maintained compressed, the compressed dust can be easily discharged from the dust collector when emptying the dust collector.
- When a quantity of dust exceeding a predetermined amount is collected inside the dust container, a display unit notifies a user that it is time to empty the dust collector, so that a user can easily recognize the time of emptying the dust collector.
- It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. 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.
