Description

Cleaner station {Cleaner station}

The present invention relates to a cleaner station, and more particularly, to a cleaner station that collects dust inside the cleaner and has a bagless type dust collecting unit.

BACKGROUND ART In general, a vacuum cleaner is a home appliance that sucks up small garbage or dust by sucking air using electricity and fills a dust bin in the product, and is commonly referred to as a vacuum cleaner.

Such cleaners may be classified into manual cleaners for cleaning while a user directly moves the cleaner, and automatic cleaners for performing cleaning while driving by itself. Manual cleaners may be classified into canister-type cleaners, upright cleaners, handheld cleaners, stick-type cleaners, robot cleaners, and the like, depending on the shape of the cleaner.

In household cleaners, canister-type vacuum cleaners have been widely used in the past, but recently, handheld vacuum cleaners and stick vacuum cleaners, which provide convenience in use by integrally providing a dust bin and a cleaner body, have been widely used.

The main body of the canister type vacuum cleaner is connected to the intake by a rubber hose or pipe, and in some cases, a brush can be inserted into the intake.

The Hand Vacuum Cleaner maximizes portability and is light in weight, but has a short length, so the cleaning area may be limited while sitting. Thus, it is used to clean localized areas, such as on a desk or sofa, or in a car.

The stick vacuum cleaner can be used standing up, so you can clean without bending your back. Therefore, it is advantageous to clean while moving a large area. If the handheld vacuum cleaner cleans a narrow space, the stick type cleaner can clean a wider space and can clean high places that are out of reach. Recently, a stick cleaner is provided in a module type, and the cleaner type is actively changed and used for various objects.

In addition, recently, a robot cleaner that self-cleans without a user's manipulation has been used. The robot cleaner automatically cleans the area to be cleaned by sucking foreign substances such as dust from the floor while traveling on its own in the area to be cleaned.

In particular, since robot cleaners are generally designed to be small in size to clean while traveling by themselves, the capacity of the dust bin for storing collected dust is small, so the user has to frequently empty the dust bin.

In order to solve the above-mentioned inconvenience, a cleaner station has been developed. The cleaner station is a device for holding a robot cleaner that has finished cleaning and sucking dust collected by the robot cleaner. In general, a vacuum cleaner station has a dust collection unit much larger than the size of a dust bin of a robot cleaner. That is, the dust collected by the robot cleaner is continuously collected in the dust collection unit of the cleaner station, and the user empties the dust collection unit of the cleaner station. According to this, compared to the case of emptying the dust bin of the robot cleaner every time, there is an advantage in that the frequency of emptying the dust by the user is drastically reduced.

On the other hand, the type of dust collection unit is largely divided into a bag type and a bagless type. The bag type is a method in which a separate bag is provided in the dust collecting unit, dust is collected in the bag, and only the bag is separated from the cleaner station and discarded. Unlike this, the bagless type does not include a separate bag in the dust collection unit, collects dust in the dust collection unit itself, and separates the dust collection unit from the cleaner station to empty the dust. At this time, since the bag is a one-time expendable item and is generally made of a plastic material, a cost problem of having to purchase the bag every time and an environmental problem causing environmental pollution occur. Therefore, in order to solve the above disadvantages, a bagless type dust collection unit is often installed in a vacuum cleaner station.

In general, a certain amount or more of dust is collected in the cleaner, and dust primarily collected by the cleaner is introduced into the cleaner station, so a large amount of dust may be introduced into the cleaner station at one time. In this case, when a large amount of dust flows into the bagless-type dust collection unit at once, the passage may be momentarily blocked, causing the cleaner station to lose its collecting function.

As Prior Document 1, US Patent Registration No. 10,463,215 is proposed. Prior Document 1 is an invention related to a discharge station. The station according to Prior Document 1 includes a base for holding a robot cleaner having a dust bin, and a canister in which a dust collector is disposed. Dust in the air introduced into the station of Prior Document 1 moves inward in the radial direction and is primarily filtered in the filter and secondarily filtered in the cyclone unit.

However, since a large amount of dust is introduced into the station at one time from the vacuum cleaner as described above, a problem in which a flow path is clogged by dust lumps may occur at the inlet end of the dust collection unit disclosed in Prior Document 1.

As Prior Document 2, US Patent Registration No. 9,492,048 is proposed. Prior Document 2 is an invention related to a dust bin detachable from a cleaning robot. Prior Document 2 proposes a station housing, a bagless type collection container having a cyclone unit, and a detachable filter. According to Prior Document 2, the collection bin can be detached from the station.

However, since Prior Document 2 only presents various embodiments of a method of docking a vacuum cleaner to a station or a method of attaching or detaching a collection container, as described above, as a large amount of dust is introduced into the station at one time, the passage is It does not suggest a solution to solve the blockage problem.

That is, the station is characterized in that dust lumps may be introduced from the cleaner and a large amount of dust is introduced at one time. However, prior art document 1 and prior art document 2 had a problem that the passage was clogged by the large amount of dust. In particular, in Prior Document 2, if a lot of dust accumulates on the top of the filter, air flow is hindered, resulting in poor collection performance of the station.

Prior Document 1: US Patent No. 10,463,215 Prior Document 2: US Patent No. 9,492,048

The cleaner 200 according to the present invention may be a robot cleaner. A robot cleaner includes a driving motor and refers to a vacuum cleaner driven by the driving motor. The cleaner 200 is disposed adjacent to one lower side of the cleaner station 100 and coupled with the cleaner station 100 .

The fact that the cleaner 200 is coupled to the cleaner station 100 means that the cleaner 200 is fixed and mechanically coupled to the cleaner station 100, the terminals of the cleaner 200 and the terminals of the cleaner station 100. It may include contacting and electrically coupling, and communication between the dust bin of the cleaner 200 and the dust collection unit 140 of the cleaner station 100 so that air flows.

The cleaner 200 includes a driving wheel (not shown). The drive wheels receive power from the drive motor of the cleaner 200 and move the cleaner 200 . The driving wheel is disposed on the bottom of the cleaner 200. The drive wheels may be arranged as a pair of left and right. Gear teeth are formed on the outer circumferential surface of the driving wheel, and can climb the inclined surface of the coupling part 120.

The cleaner 200 includes casters (not shown). The caster is a component for steering the cleaner 200. The caster is rotatably disposed around a central axis in a vertical direction.

The mop is disposed on one side of the bottom of the cleaner 200. The mop is disposed on the opposite side of the caster, centered on an imaginary line connecting the left driving wheel and the right driving wheel.

The cleaner station 100 is a component that is combined with the cleaner 200 to charge the cleaner 200, to suck dust collected in the dust bin of the cleaner 200, or to safely store the cleaned cleaner 200. .

The housing 110 forms an exterior of the cleaner station 100 and forms a space in which components are accommodated.

The housing 110 may have a vertical height longer than a left-right width or a front-back width. By having such an arrangement, the space occupied by the room in which the cleaner station 100 is installed can be minimized.

The housing 110 may be composed of an upper cover 111 and side covers 112 and 113.

The upper cover 111 is disposed on the upper surface of the housing 110.

Referring to FIG. 2 , the upper cover 111 may be opened and closed. Specifically, the rear end of the upper cover 111 is hinged to the housing 110 body, rotates upward, and the upper surface of the housing 110 is opened and closed. When the upper cover 111 is opened, the pre-filter 161 may be detached.

The first side cover 112 is disposed on the side of the housing 110 . Specifically, the first side cover 112 is disposed on the left side and front of the housing 110.

Referring to Figure 2, the first side cover 112 can be opened and closed. Specifically, the rear end of the first side cover 112 is hinged to the housing 110 body, rotates to the left, and the front of the housing 110 is opened and closed. When the first side cover 112 is opened, the dust collection unit 140 can be detached.

The second side cover 113 is disposed on the side of the housing 110. Specifically, the second side cover 113 is disposed on the right side and rear side of the housing 110 .

The second side cover 113 covers the suction passage 130 and the discharge passage 170 . A silencer is provided on the inner surface of the second side cover 113 to prevent noise generated inside the housing 110 from being emitted to the outside.

The coupler 120 is a component to which the cleaner 200 is coupled and connected to at least one or more of the components of the cleaner 200 . The coupling part 120 is disposed on the housing 110 and includes a coupling surface to which at least a portion of the cleaner 200 is coupled.

The coupling part 120 may cover the lower surface of the housing 110 and extend forward of the housing 110 .

The coupling part 120 may form an inclined surface having a low front end and a high rear end. Accordingly, the cleaner 200 may enter the coupling portion 120 while moving from the front to the rear of the coupling portion 120 .

The coupling part 120 includes a driving wheel seating part 121 . The driving wheel seating part 121 seats the driving wheel of the cleaner 200 thereon. The driving wheel seating portion 121 is formed by being recessed downward from a coupling surface of the coupling portion 120 of the coupling portion 120 . The driving wheel mounting portion 121 may be formed as a left and right pair to correspond to the driving wheel.

Coupling portion 120 includes a mop mounting portion 122. The mop mounting portion 122 is disposed below the mop of the cleaner 200 when the cleaner 200 is coupled to the cleaner station 100 .

The coupling part 120 includes a caster guide 123. The caster guide 123 is formed on a trajectory along which the caster of the cleaner 200 passes when the cleaner 200 is coupled to the cleaner station 100 . The caster guide 123 is formed in a downwardly recessed groove shape. The caster guide 123 extends in the front-rear direction, which is the direction in which the cleaner 200 enters.

The coupling part 120 includes a suction port 124 . The inlet 124 of the coupling part 120 is connected to the inlet end of the suction passage 130 . The inlet 124 of the coupling part 120 communicates with the outlet of the dust bin of the cleaner 200 .

The coupling part 120 includes a charging terminal 125 . The charging terminal 125 is disposed at the front end of the coupling part 120 and protrudes upward. The charging terminal 125 of the coupling part 120 is in contact with a charging terminal (not shown) of the cleaner, so that the cleaner 200 and the cleaner station 100 are electrically connected.

A dust collector installation space 114 is formed in the housing 110 . The dust collector installation space 114 corresponds to a part of the inner space of the housing 110 . The dust collector installation space 114 is isolated from the external space by the first side cover 112 and the second side cover 113 . When the first side cover 112 rotates, the dust collection unit installation space 114 is opened, and the dust collection unit 140 can be attached or detached.

The suction passage 130 has an inlet end communicating with a dust bin (not shown) of the vacuum cleaner, and an outlet end communicating with the air inlet 1411 of the dust collection unit 140 . The suction passage 130 extends forward from the inside of the coupling part 120 . The inlet end of the suction passage 130 is connected to the suction port 124 of the coupling part 120 and communicates with the dust bin of the vacuum cleaner, so that dust from the dust bin of the cleaner may flow into the suction passage 130 .

The outlet end of the suction passage 130 is disposed above the inlet end. The suction passage 130 extends upward from inside the cleaner station 100 . An outlet end of the suction passage 130 is connected to the air inlet 1411 of the dust collection unit 140, so that dust flowing through the suction passage 130 may flow to the dust collection unit 140.

Inside the suction passage 130, air rises from the bottom to the top. Since the inside of the suction passage 130 is formed in a simple cylindrical structure, air resistance hardly occurs therein. Therefore, dust included in the air can flow to the outlet end of the suction passage 130 without air resistance.

The dust collection unit 140 is a component that collects dust inside the dust bin of the vacuum cleaner. The dust collection unit 140 is accommodated inside the housing 110 .

The dust collecting unit 140 according to the present invention is a bagless type. The type of dust collecting unit 140 is largely divided into a bag type and a bagless type. The bag type is a method in which a separate bag is provided in the dust collection unit 140 to collect dust in the bag, and only the bag is separated from the cleaner station 100 and discarded. Unlike this, the bagless type does not have a separate bag in the dust collection unit 140, collects dust in the dust collection unit 140 itself, and removes dust by separating the dust collection unit 140 itself from the cleaner station 100. way to empty it.

Generally, more than a certain amount of dust is collected in the cleaner 200, and dust primarily collected by the cleaner 200 is introduced into the cleaner station 100, so a large amount of dust may be introduced at once. At this time, as too much dust flows into the bagless-type dust collection unit 140 at once, the passage may be blocked and the cleaner station 100 may lose its collecting function. Accordingly, the cleaner station 100 according to the present invention includes means for removing dust stuck in the outlet and compressing the collected dust, so that the collecting function of the cleaner station 100 can be secured.

The dust collecting unit 140 includes a dust collecting body 141 , a mesh 144 , and a compression plate 142 .

The dust collecting body 141 forms the outer shape of the dust collecting part 140 and has an internal space in which dust can be collected.

The dust collecting body 141 is formed in a cylindrical shape around the shaft 1414. The shaft 1414 is disposed in the inner space of the dust collecting body 141 and extends in the longitudinal direction. The shaft 1414 may be disposed parallel to the longitudinal direction of the suction passage 130, and specifically, the shaft 1414 may be disposed in a vertical direction. A rotating plate 1422 is rotatably coupled to the shaft 1414 .

The dust collecting body 141 is formed with an air inlet 1411 through which air is introduced into the inner space and an air outlet 1412 through which air from the inner space is discharged. The air inlet 1411 communicates with the intake passage 130 and the air outlet 1412 communicates with the discharge passage 170 .

The air inlet 1411 is formed on one of the bottom surface, outer wall surface, and top surface of the dust collecting body 141, and the air outlet 1412 is an air inlet port on the bottom surface, outer wall surface, and upper surface of the dust collecting body 141 ( 1411) may be formed on one of the faces except for the face formed. Referring to FIG. 7 , the air inlet 1411 is formed on the outer wall surface of the dust collecting body 141, and the air outlet 1412 is formed on the upper surface of the dust collecting body 141.

A direction in which air is introduced from the air inlet 1411 may be different from a direction in which air is discharged from the air outlet 1412 . Air may be introduced from the air inlet 1411 in a direction crossing the longitudinal direction of the shaft 1414 , and air may be discharged from the air outlet 1412 in a direction parallel to the longitudinal direction of the shaft 1414 . By having such an arrangement, since the flow direction of the air is changed at least once inside the dust collecting body 141, dust can be separated from the air by inertia.

The air outlet 1412 is formed on the upper surface of the dust collecting body 141. Air is discharged to the outside of the dust collecting body 141 while rising from the air outlet 1412 . Therefore, the dust contained in the air from the air outlet 1412 is not discharged to the upper part of the dust collecting body 141 by gravity and descends.

The upper cover 146 of the dust collecting unit covers at least a part of the upper surface of the dust collecting body 141 . The upper cover 146 of the dust collecting unit is spaced apart from the upper part of the air outlet 1412, and at least a part thereof overlaps the air outlet 1412 vertically.

The upper cover 146 of the dust collection unit may be divided into a first upper cover 1461 and a second upper cover 1462 .

The first upper cover 1461 and the second upper cover 1462 may be disposed in parallel. The first upper cover 1461 and the second upper cover 1462 may be spaced apart at regular intervals. The first upper cover 1461 is disposed above the second upper cover 1462 .

A through hole through which air can be discharged is formed in the first upper cover 1461 .

The cyclone unit 145 may be connected to the second upper cover 1462 .

A dust outlet 1413 for discharging collected dust is formed in the dust collection body 141 . Referring to FIG. 7 , the dust outlet 1413 is formed on the lower surface of the dust collecting body 141 .

The discharge cover 143 covers the dust outlet 1413. Referring to FIG. 7 , the discharge cover 143 is disposed on the lower surface of the dust collecting body 141 . The discharge cover 143 is hinged to the dust collection body 141 and opens and closes the dust outlet 1413 while rotating.

A power transmission member 1425 may be disposed on the discharge cover 143 .

The mesh 144 is a component that filters dust from the air discharged from the dust collecting body 141 . A mesh 144 covers the air outlets 1412 .

The mesh 144 is formed with a number of holes. A plurality of holes may be formed in the mesh 144 by intertwining a plurality of wires.

The mesh 144 filters dust from the air in a physical way. That is, dust smaller than the hole size of the mesh 144 passes through the mesh 144, and dust larger than the hole size of the mesh 144 does not pass through the mesh 144. Large dust that does not pass through the mesh 144 descends to the lower part of the dust collecting body 141 or is adsorbed to the lower surface of the mesh 144 .

Mesh 144 is disposed radially outwardly and spaced from shaft 1414 .

The mesh 144 may be formed in a shape similar to a semicircle. At this time, the mesh 144 may be formed to be convex outward in the radial direction.

The compression plate 142 is a component that compresses the dust collected in the inner space of the dust collection body 141 . The compression plate 142 is rotatably disposed in the inner space of the dust collecting body 141, and rotates to clean the mesh 144.

The first function of the compression plate 142 is to compress the dust collected in the inner space of the dust collecting body 141, and the second function is to sweep away the dust adsorbed on the mesh 144.

The compression plate 142 may include a fixed plate 1421, a rotating plate 1422, and a mesh cleaner 1423.

Referring to FIG. 10 , the fixing plate 1421 extends from the outer wall surface of the dust collecting body 141 toward the shaft 1414 .

The fixing plate 1421 may be integrally formed with the dust collecting body 141 . The fixing plate 1421 protrudes from the dust collecting body 141 and extends radially inward. An inner end of the fixing plate 1421 may be disposed adjacent to the shaft 1414 but spaced apart from the shaft 1414 . Therefore, the fixed plate 1421 does not interfere with the rotation of the rotating plate 1422 .

The fixing plate 1421 extends along the longitudinal direction of the shaft 1414 .

The fixing plate 1421 may be formed in a flat plate shape.

Referring to FIG. 10 , a rotating plate 1422 is rotatably coupled to a shaft 1414 and extends radially outward.

The rotating plate 1422 surrounds at least a portion of the outer circumferential surface of the shaft 1414 . The rotating plate 1422 has a cylindrical shape having a hollow, and a shaft 1414 may be inserted into the hollow.

The rotating plate 1422 extends radially outward. The outer end of the rotating plate 1422 is adjacent to the inner circumferential surface of the dust collecting body 141, but is disposed spaced apart from the dust collecting body 141. Thus, the rotation plate 1422 can rotate with the shaft 1414 as a rotation center axis.

When the rotary plate 1422 rotates, the rotary plate 1422 may be disposed in a virtual space formed by the air inlet, the central axis of the shaft, and the fixing plate 1421 . By having such an arrangement, when the rotating plate 1422 rotates, the dust is moved to a space where air does not flow, so that the air flow inside the dust collecting body is not hindered.

Referring to FIG. 10, the operation of the compression plate 142 will be described.

10A is a state diagram before the compression plate 142 moves, and FIG. 10B is a state diagram after the compression plate 142 moves.

Referring to FIG. 10A , with respect to the shaft 1414, a fixing plate 1421 is disposed at a 3 o'clock direction and a compression plate 142 is disposed at a 6 o'clock direction. The air inlet 1411 is disposed in the 1 o'clock direction of the shaft 1414, and the air outlet 1412 is disposed in the 9 o'clock direction of the shaft 1414, although not shown. Accordingly, dust may exist from the 1 o'clock direction to the 9 o'clock direction with respect to the shaft 1414 .

Referring to FIG. 10B , the rotating plate 1422 rotates clockwise (CW) around the shaft 1414, and may finally rotate up to the 2 o'clock direction of the shaft 1414. At this time, the dust inside the dust collecting body 141 is compressed and located between the rotating plate 1422 and the fixing plate 1421.

After FIG. 10B, the rotating plate 1422 may return to the state of FIG. 10A.

The user may detach the dust collector 140 by gripping the handle 181 and pulling it forward. The handle 181 is rotatably coupled to the dust collector, rotates only when detached, and protrudes forward. When the handle 181 is mounted, it occupies only a minimum space in the interior space of the cleaner station 100, Space can be used efficiently.

A handle insertion groove 1415 is formed in the dust collecting body 141 . The handle insertion groove 1415 forms a space into which the handle 181 is inserted when the handle 181 is mounted. The handle insertion groove 1415 is formed by recessing inward from one side of the dust collecting body 141. When the handle 181 is mounted, the handle 181 rotates sideways around the central axis of rotation and is inserted into the handle insertion groove 1415.

The handle 181 is hinged to the dust collecting body 141. The handle hinge 182 protrudes from one side of the dust collecting body 141. The handle hinge 182 is inserted into one side of the handle 181 or passes through the handle 181 . When the handle hinge 182 passes through the handle 181, a fastening member 183 may be fastened to an end of the handle hinge 182.

The rotation center axis of the handle 181 is disposed parallel to the rotation center axis of the compression plate 142. Referring to FIG. 6 , the rotation center axis of the handle 181 is disposed in the vertical direction. Referring to FIG. 6A around the rotation center axis, when the dust collector 140 is mounted, the handle 181 rotates counterclockwise and is inserted into the handle insertion groove 1415.

The horizontal portion 1811 of the handle extends outward in the radial direction from the dust collecting body 141 at a glance. A handle hinge 182 is inserted or penetrated into the inner end of the horizontal portion 1811 of the handle. The vertical portion 1812 of the handle is bent at an outer end of the horizontal portion 1811 of the handle and extends in a direction different from the extending direction of the horizontal portion 1811 . Specifically, the vertical portion 1812 of the handle extends perpendicular to the direction in which the horizontal portion 1811 extends.

The pre-filter 181 is a component that filters dust from the air. Specifically, the pre-filter 161 is disposed upstream of the HEPA filter and primarily filters large dust from air flowing into the HEPA filter.

The pre-filter 161 is disposed above the dust collection unit 140 and communicates with the air outlet 1412 of the dust collection unit 140 .

The pre-filter 161 is disposed above the dust collection unit 140, and dust positioned between the pre-filter 161 and the dust collection unit 140 descends due to gravity and is deposited on the dust collection unit 140. According to the present invention, since the capacity of the dust collection unit 140 is smaller than the capacity of the pre-filter 161, it is possible to collect dust in the dust collection unit 140 to maximize the collection capacity of the cleaner station 100. there is.

The pre-filter case 1611 forms the outer shape of the pre-filter 161 and forms a space for accommodating the filtering member 1614 therein.

The filtering member 1614 of the pre-filter is a component that separates dust from the air introduced into the pre-filter 161 . The filtering member 1614 of the pre-filter separates dust from the air by a physical method. That is, the filtering member 1614 of the pre-filter has a plurality of through-holes, passes dust smaller than the through-holes, and filters dust larger than the through-holes.

In the pre-filter 161, air is introduced in a direction parallel to the direction in which air is discharged from the air outlet 1412 of the dust collecting body 141, and air is discharged in a crossing direction. Referring to FIG. 11 , the pre-filter 161 has an inlet 1612 formed on a lower surface and an outlet 1613 formed on a side surface. Thus, air flows in upward toward the pre-filter 161 and is discharged from the pre-filter 161 sideways. By having this arrangement, the direction in which the air flows inside the pre-filter 161 can be changed at least once, and can evenly pass through the surface of the filtering member 1614 as a whole.

The inlet 1612 of the pre-filter may be disposed biased to one side based on an imaginary center line dividing the pre-filter 161 into left and right sides. The outlet 1613 of the pre-filter may be formed long in one direction.

The pre-filter 161 is attached and detached in a direction different from the direction in which the dust collector 140 is attached and detached. The direction in which the pre-filter 161 is attached to or detached from the housing 110 intersects the direction in which the pre-filter 161 is attached to or detached from the housing 110 . Referring to FIG. 2 , the pre-filter 161 moves downward toward the upper surface of the housing 110 when the upper cover 111 is opened and is mounted. Conversely, the pre-filter 161 moves upward from the housing 110 and is detached. This is compared to attaching and detaching the dust collector 140 to the front or rear of the housing 110 .

The front end of the pre-filter 161 is disposed above the rear end. In more detail, referring to FIG. 12, the filtering member 1614 of the pre-filter has a front end higher than the rear end. By having this arrangement, the direction in which the air flows inside the pre-filter 161 can be arranged as close to vertical as possible from the surface of the filtering member 1614 .

The inlet 161 of the pre-filter faces the lower surface of the filtering member 1614, and the outlet faces the upper surface of the filtering member 1614. Therefore, when a large amount of dust is filtered by the filtering member 1614, it falls to the lower portion of the filtering member 1614 by gravity, thereby preventing more than a certain amount of dust from adsorbing to the filtering member 1614 and minimizing the amount of air. It has the effect of securing liquidity.

The discharge passage 170 has an inlet end communicating with the air outlet 1412 of the dust collection unit 140 and an outlet end communicating with the outside at one side of the housing 110 .

The discharge passage 170 passes through the pre-filter 161 - the suction motor - the HEPA filter and communicates with the outside of the cleaner station 100.

The discharge passage 170 may be disposed parallel to the suction passage 130 .

The outlet end of the discharge passage 170 is disposed lower than the inlet end. That is, air descends from top to bottom inside the discharge passage 170 .

The cross section of the discharge passage 170 may have a diameter in the first direction larger than a diameter in the second direction. The cross section of the discharge passage 170 may be formed in an elliptical shape, unlike the circular cross section of the suction passage 130 .

A cyclone unit 145 may be disposed in the dust collection unit 140 . The cyclone unit 145 is a component that separates dust from air by centrifugal force. The cyclone unit 145 is disposed on the outer circumferential surface of the dust collecting body 141 and communicates with the air outlet 1412.

The cyclone unit 145 is disposed downstream of the air inlet 1411 of the dust collecting body 141 and disposed upstream of the air outlet 1412.

The cyclone unit 145 is disposed on the outer circumferential surface of the dust collecting body 141. Referring to FIG. 7 , the dust collecting body 141 may be formed in a cylindrical shape, and the cyclone unit 145 may be disposed to surround at least a portion of an outer circumferential surface of the dust collecting body 141 .

The cyclone unit 145 may be integrally formed with the dust collecting body 141 . Although not shown, unlike the above, the cyclone unit 145 may be formed separately from the dust collecting body 141 and then combined.

The cyclone unit 145 may be divided into an outer tube and an inner tube. The exterior of the cyclone unit 145 is integrally formed with the dust collecting body 141. The inner tube of the cyclone unit 145 may be formed on the upper cover 146 of the dust collection unit 140, and is specifically formed on the second upper cover 1462.

The central axis of the inner tube of the cyclone unit 145 is disposed on the same line as the central axis of the outer tube. Thus, the air introduced into the cyclone unit 145 spirals in the space between the inner tube and the outer tube, and dust is separated by centrifugal force. The separated dust descends to the lower part of the cyclone unit 145, and the air is discharged to the outside through the inner space of the inner tube.

The air discharged from the cyclone unit 145 is directed to the pre-filter 161 through the air outlet 1412 formed in the first upper cover 1461 .

The dust collecting motor 150 is a component that generates air flow inside the cleaner station 100 . The dust collecting motor 150 is disposed between the cleaner 200 and the dust collecting part 140 when the cleaner 200 is coupled.

The dust collecting motor 150 is disposed under the compression motor 1424.

The pre-filter 161 is disposed on the opposite side of the dust collecting motor 150 with the dust collecting part 140 as the center.

The pre-filter 161 and the HEPA filter are spaced apart from each other. Specifically, the pre-filter 161 is disposed on the opposite side of the HEPA filter with the dust collector 140 as the center. The pre-filter 161 is disposed on the opposite side of the HEPA filter with the dust collecting motor 150 as the center.

The compression motor 1424 is disposed on the same side as the dust collecting motor 150 with the dust collecting part 140 as the center. That is, the compression motor 1424 and the dust collection motor 150 may be disposed adjacent to each other. Both the compression motor 1424 and the dust collecting motor 150 are components that generate noise. Therefore, by arranging the compression motor 1424 and the dust collecting motor 150 in one space and arranging the noise member to surround the space, noise generation of the cleaner station 100 is minimized by arranging the noise member to a minimum. can do.

The air flow of the cleaner station 100 according to the present invention configured as described above will be described as follows. When the cleaner 200 is coupled to the cleaner station 100, the dust bin of the cleaner 200 communicates with the suction passage 130 of the cleaner station 100. When the dust collecting motor 150 operates, the air flows through the suction passage 130 - the dust collection part 140 - the cyclone part - the pre-filter 161 - the discharge passage 170 - the dust collecting motor 150 - the HEPA filter, and then the vacuum cleaner. It is discharged to the outside of the station 100.

The dust collector 140 according to the present invention separates dust from introduced dust. Since the air outlet 1412 is formed on the upper surface of the dust collector 140 and the mesh 144 is disposed in the air outlet 1412, air passes through the mesh 144 and dust does not pass through the mesh 144. can not do it.

A compression plate 142 is disposed in the dust collecting unit 140 . The compression plate 142 is rotatably coupled to the shaft 1414 of the dust collecting body 141. Specifically, when the rotating plate 1422 rotates, dust collected inside the dust collecting body 141 is compressed by the rotating plate 1422 and the fixing plate 1421 . As dust is compressed and its volume is reduced, the dust collection unit 140 can additionally collect more dust, and the operating time of the cleaner station 100 can be improved.

A mesh cleaner 1423 is disposed on the compression plate 142 . The mesh cleaner 1423 is disposed on top of the rotating plate 1422 and sweeps away dust adsorbed on the mesh 144 when the rotating plate 1422 rotates.
