Description

[0001] This application is a divisional application with application number 202180044246.7, application date June 10, 2021, and invention name “Vacuum cleaner station and method for controlling a vacuum cleaner station”. Technical Field

[0002] The present disclosure relates to a cleaning station and a method of controlling the cleaning station, and more particularly, to a cleaning station configured to suck dust stored in a cleaner into the cleaning station and a method of controlling the cleaning station. Background Art

[0003] Generally, a cleaner refers to an electrical appliance that sucks in small garbage or dust by using electricity to suck in air and fills a dust collection box provided in the product with the garbage or dust. Such a cleaner is generally called a vacuum cleaner.

[0004] Cleaners can be divided into manual cleaners that are directly moved by a user to perform cleaning operations and automatic cleaners that perform cleaning operations while autonomously traveling. According to the shape of the cleaner, manual cleaners can be divided into drum cleaners, upright cleaners, portable cleaners, pole cleaners, etc.

[0005] In the past, drum cleaners were widely used as household cleaners. However, recently, there is a growing tendency to use handheld cleaners and pole cleaners in which a dust box and a cleaner body are integrally provided to improve the convenience of use.

[0006] In the case of a cylinder cleaner, a main body and a suction port are connected by a rubber hose or a tube, and in some cases, the cylinder cleaner may be used in a state in which a brush is fitted into the suction port.

[0007] A hand-held cleaner (hand-held vacuum cleaner) has the greatest portability and is lightweight. However, because the hand-held cleaner has a short length, there may be a limitation on the cleaning area. Therefore, the hand-held cleaner is used to clean places such as tables, sofas, or vehicle interiors.

[0008] The user can use the pole cleaner when standing, and therefore can perform cleaning operations without bending his / her waist. Therefore, the pole cleaner is conducive to cleaning a wide area when the user moves in the area. The portable cleaner can be used to clean narrow spaces, while the pole cleaner can be used to clean wide spaces and can also be used for high places that the user's hands cannot reach. Recently, modular pole cleaners are provided so that the type of cleaner is actively changed and used to clean various places.

[0009] In addition, recently, a robot cleaner that autonomously performs a cleaning operation without a user's operation is used. When the robot cleaner autonomously travels in the area to be cleaned, the robot cleaner automatically cleans the area to be cleaned by sucking foreign matter such as dust from the floor.

[0010] To this end, the robot cleaner includes a distance sensor configured to detect a distance from obstacles (eg, furniture, office supplies, or walls) installed in an area to be cleaned, and left and right wheels for moving the robot cleaner.

[0011] In this case, the left and right wheels are configured to be rotated by the left and right wheel motors, respectively, and the robot cleaner cleans the room while autonomously changing its direction by operating the left and right wheel motors.

[0012] However, since the related art handheld cleaner, pole cleaner, or robot cleaner has a small-capacity dust box for storing collected dust, it is inconvenient for the user since the user needs to frequently empty the dust box.

[0013] Furthermore, since dust is scattered during the process of emptying the dust box, there is a problem that the scattered dust has a harmful effect on the health of the user.

[0014] Furthermore, if the residual dust is not removed from the dust box, there is a problem that the suction power of the cleaner becomes poor.

[0015] Furthermore, if the residual dust is not removed from the dust box, there is a problem that the residual dust causes an unpleasant odor.

[0016] Patent document US2020-0129025A1 discloses a dust box combined with a stick vacuum cleaner.

[0017] In the combination of a dust box and a vacuum cleaner of this patent document, the vacuum cleaner is arranged to be coupled to the dust box.

[0018] However, the problem with this patent document is that the user needs to directly assemble the vacuum cleaner and the dust box.

[0019] In addition, there is a problem in that it is impossible to compress the dust in the vacuum cleaner to remove the dust remaining in the cleaner.

[0020] Meanwhile, patent document US10595692B2 discloses a discharge station of a debris box having a robot cleaner.

[0021] In this patent document, a station to which a robot cleaner is docked is provided, and the station has a flow path through which dust is sucked in a direction perpendicular to the ground.

[0022] In this patent document, a sensor is provided to sense docking between the robot cleaner and the station, and during the docking process, a motor is operated to suck dust from the robot cleaner.

[0023] However, in this patent document, dust is sucked only in a state where the robot cleaner is coupled to the connector of the station, but there is no component to recognize whether the cleaner is coupled, fix the cleaner, and open or close the suction port.

[0024] Furthermore, the patent document has a problem in that it is impossible to compress the dust in the cleaner to remove the dust remaining in the cleaner.

[0025] At the same time, patent document KR2020-0037199A discloses a cleaner.

[0026] This patent document discloses a cleaner capable of compressing dust in a dust box and removing the dust.

[0027] However, the problem with this patent document is that the user needs to directly push the rod to compress the dust in the dust box. Summary of the invention

[0102] According to the cleaner station and the method of controlling the cleaner station of the present disclosure, it is possible to eliminate the inconvenience caused by the user needing to always empty the dust box.

[0103] In addition, since the dust in the dust box is sucked into the station when the dust box is emptied, it is possible to prevent the dust from being scattered.

[0104] In addition, the dust passage hole can be opened by detecting the connection of the cleaner without a separate operation of the user, and the dust in the dust collecting box can be removed according to the operation of the dust collecting motor, thus providing convenience for the user.

[0105] Furthermore, the pole cleaner and the robot cleaner may be simultaneously coupled to the cleaner station, and dust in the dust box of the pole cleaner and dust in the dust box of the robot cleaner may be selectively removed as needed.

[0106] Furthermore, when the cleaner is coupled to the cleaner station, the coupling of the cleaner may be detected, the cleaner may be automatically fixed, the suction port (door) of the cleaner station may be opened, and the cover of the dust box of the cleaner may be opened.

[0107] In addition, when the cleaner station detects the coupling of the dust box, the rod is pulled to compress the dust box so that residual dust does not remain in the dust box, and thus, the suction power of the cleaner can be increased.

[0108] Furthermore, by preventing the residual dust from remaining in the dust box, unpleasant odors caused by the residual dust can be removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0139] Figure 1 is a perspective view showing a dust removal system for a cleaner including a cleaner station, a first cleaner, and a second cleaner according to an embodiment of the present disclosure, and Figure 2 : is a schematic diagram showing the configuration of a dust removal system for a cleaner according to an embodiment of the present disclosure.

[0140] Reference Figure 1 and Figure 2 , the dust removal system 10 according to the embodiment of the present specification may include a cleaner station 100 and cleaners 200 and 300. In this case, the cleaners 200 and 300 may include a first cleaner 200 and a second cleaner 300. Meanwhile, the present embodiment may be implemented without some of the above components, and additional components are not excluded.

[0141] The dust removal system 10 may include a cleaner station 100. A first cleaner 200 and a second cleaner 300 may be disposed on the cleaner station 100. The first cleaner 200 may be coupled to a side surface of the cleaner station 100. Specifically, a main body of the first cleaner 200 may be coupled to a side surface of the cleaner station 100. The second cleaner 300 may be coupled to a lower portion of the cleaner station 100. The cleaner station 100 may remove dust from a dust box 220 of the first cleaner 200. The cleaner station 100 may remove dust from a dust box (not shown) of the second cleaner 300.

[0142] at the same time, Figure 3 is a view for explaining a first cleaner of a dust removal system according to an embodiment of the present disclosure, and Figure 42 is a view for explaining the center of gravity of the first cleaner according to the embodiment of the present disclosure.

[0143] First, to help understand the cleaner station 100 according to the present disclosure, reference will be made to Figures 1 to 4 The structure of the first cleaner 200 is described.

[0144] The first cleaner 200 may refer to a cleaner configured to be manually operated by a user. For example, the first cleaner 200 may refer to a handheld cleaner or a pole-type cleaner.

[0145] The first cleaner 200 may be mounted on the cleaner station 100. The first cleaner 200 may be supported by the cleaner station 100. The first cleaner 200 may be coupled to the cleaner station 100.

[0146] The first cleaner 200 may include a main body 210. The main body 210 may include a main body housing 211, a suction portion 212, a dust separation portion 213, a suction motor 214, an exhaust cover 215, a handle 216, an extension portion 217, and an operation portion 218.

[0147] The main body housing 211 may define an appearance of the first cleaner 200. The main body housing 211 may provide a space in which a suction motor 214 and a filter (not shown) may be accommodated. The main body housing 211 may be formed in a shape similar to a cylinder.

[0148] The suction portion 212 may protrude outward from the main body housing 211. For example, the suction portion 212 may be formed in a cylindrical shape with an internal opening. The suction portion 212 may be communicated with the extension pipe 280. The suction portion 212 may provide a flow path (hereinafter, referred to as a "suction flow path") through which dust-containing air may flow.

[0149] Meanwhile, in the present embodiment, it is possible to define an imaginary center line passing through the center of the cylindrical suction portion 212. That is, it is possible to define an imaginary suction flow path center line a2 passing through the center of the suction flow path.

[0150] In this case, the suction flow path center line a2 may be an imaginary line connecting the centers of gravity on planes formed by cutting the suction portion 212 in the axial direction and the radial direction.

[0151] The dust separation part 213 may communicate with the suction part 212. The dust separation part 213 may separate dust introduced into the dust separation part 213 through the suction part 212. The dust separation part 213 may communicate with the dust collecting box 220.

[0152] For example, the dust separation part 213 may be a cyclone part capable of separating dust using a cyclone. In addition, the dust separation part 213 may be communicated with the suction part 212. Therefore, the air and dust introduced by the suction part 212 flow spirally along the inner peripheral surface of the dust separation part 213. Therefore, a cyclone may be generated around the central axis of the dust separation part 213.

[0153] Meanwhile, in the present embodiment, the central axis of the cyclone portion may be a virtual cyclone central axis a4 extending in the vertical direction.

[0154] In this case, the cyclone center axis a4 may be an imaginary line connecting the centers of gravity on planes formed by cutting the dust separating portion 213 in the axial direction and the radial direction. For example, the cyclone center axis a4 may be defined coaxially with a motor axis a1 to be described below.

[0155] The suction motor 214 may generate suction for sucking air. The suction motor 214 may be accommodated in the main body housing 211. The suction motor 214 may generate suction by rotating. For example, the suction motor 214 may be formed in a shape similar to a cylinder.

[0156] Meanwhile, in the present embodiment, the imaginary motor axis a1 may be formed by extending the central axis of the suction motor 214 .

[0157] In this case, the motor axis a1 may be an imaginary line connecting centers of gravity on a plane formed by cutting the suction motor 214 in the axial direction and the radial direction.

[0158] The exhaust cover 215 may be provided at one side in the axial direction of the main body housing 211. The exhaust cover 215 may accommodate a filter for filtering air. For example, a HEPA filter may be accommodated in the exhaust cover 215.

[0159] The exhaust cover 215 may have an exhaust port 215 a for exhausting air introduced by the suction force of the suction motor 214 .

[0160] A flow guide may be provided on the exhaust cover 215. The flow guide may guide a flow of air to be discharged through the exhaust port 215a.

[0161] The user can grasp the handle 216. The handle 216 may be provided at the rear side of the suction motor 214. For example, the handle 216 may be formed in a shape similar to a cylinder. Alternatively, the handle 216 may be formed in a curved cylindrical shape. The handle 216 may be provided at a predetermined angle relative to the main body housing 211, the suction motor 214 or the dust separation portion 213.

[0162] Meanwhile, in the present embodiment, the imaginary handle axis a3 may be formed by extending the central axis of the handle 216 .

[0163] In this case, the handle axis a3 may be an imaginary line connecting centers of gravity on planes formed by cutting the handle 216 in the axial direction and the radial direction.

[0164] The shaft of the suction motor 214 may be disposed between the suction portion 212 and the handle 216. That is, the motor axis a1 may be disposed between the suction portion 212 and the handle 216.

[0165] Furthermore, the handle axis a3 may be disposed at a predetermined angle relative to the motor axis a1 or the suction flow path center line a2. Therefore, there may be an intersection point where the handle axis a3 intersects the motor axis a1 or the suction flow path center line a2.

[0166] Meanwhile, the motor axis a1, the suction flow path center line a2, and the handle axis a3 may be disposed on the same plane S1.

[0167] With this configuration, the center of gravity of the entire first cleaner 200 according to the present disclosure may be disposed symmetrically with respect to the plane S1.

[0168] Meanwhile, in an embodiment of the present disclosure, the forward direction may refer to a direction in which the suction part 212 is provided based on the suction motor 214 , and the backward direction may refer to a direction in which the handle 216 is provided.

[0169] The upper surface of the handle 216 may define the appearance of a portion of the upper surface of the first cleaner 200. Therefore, when the user grasps the handle 216, components of the first cleaner 200 may be prevented from coming into contact with the user's arm.

[0170] The extension portion 217 may extend from the handle 216 toward the main body housing 211. At least a portion of the extension portion 217 may extend in a horizontal direction.

[0171] The operating portion 218 may be provided on the handle 216. The operating portion 218 may be provided on an inclined surface formed in an upper region of the handle 216. A user may input an instruction to operate or stop the first cleaner 200 through the operating portion 218.

[0172] The first cleaner 200 may include a dust box 220. The dust box 220 may communicate with the dust separation part 213. The dust box 220 may store dust separated by the dust separation part 213.

[0173] The dust box 220 may include a dust box body 221, a discharge cover 222, a dust box compression rod 223, and a compression member (not shown).

[0174] The dust box body 221 may provide a space capable of storing dust separated by the dust separating portion 213. For example, the dust box body 221 may be formed in a shape similar to a cylinder.

[0175] Meanwhile, in the present embodiment, the imaginary dust box axis a5 may be formed by extending the central axis of the dust box body 221 .

[0176] In this case, the dust box axis a5 may be an imaginary line connecting the centers of gravity on planes formed by cutting the dust box 220 in the axial direction and the radial direction. For example, the dust box axis a5 may be defined coaxially with the motor axis a1.

[0177] Therefore, the dust box axis a5 may also be disposed on a plane S1 including the motor axis a1, the suction flow path center line a2, and the handle axis a3.

[0178] A portion of the lower side of the dust box body 221 may be opened. In addition, a lower extension 221a may be formed at the lower side of the dust box body 221. The lower extension 221a may be formed to block a portion of the lower side of the dust box body 221.

[0179] The dust box 220 may include a discharge cover 222. The discharge cover 222 may be provided at the lower side of the dust box 220. The discharge cover 222 may selectively open or close the lower side of the dust box 220 that is opened downward.

[0180] The discharge cover 222 may include a cover body 222a and a hinge portion 222b. The cover body 222a may be formed to block a portion of the lower side of the dust box body 221. The cover body 222a may be rotated downward around the hinge portion 222b. The hinge portion 222b may be disposed adjacent to the battery housing 230. The discharge cover 222 may be coupled to the dust box 220 by hook engagement.

[0181] Meanwhile, the dust box may further include a coupling rod 222c. The discharge cover 222 may be separated from the dust box 220 by the coupling rod 222c. The coupling rod 222c may be disposed at the front side of the dust box. Specifically, the coupling rod 222c may be disposed on the outer surface of the front side of the dust box 220. When an external force is applied to the coupling rod 222c, the coupling rod 222c may elastically deform the hook extending from the cover body 222a so as to release the hook engagement between the cover body 222a and the dust box body 221.

[0182] When the discharge cover 222 is closed, the lower side of the dust box 220 may be blocked (sealed) by the discharge cover 222 and the lower extension 221 a.

[0183] The dust box 220 may include a dust box compression rod 223. The dust box compression rod 223 may be disposed outside the dust box 220 or the dust separation portion 213. The dust box compression rod 223 may be disposed outside the dust box 220 or the dust separation portion 213 so as to be able to move upward and downward. The dust box compression rod 223 may be connected to a compression member (not shown). When the dust box compression rod 223 is moved downward by an external force, the compression member (not shown) may also move downward. Therefore, convenience may be provided for the user. The compression member (not shown) and the dust box compression rod 223 may be returned to the original position by an elastic member (not shown). Specifically, when the external force applied to the dust box compression rod 223 is eliminated, the elastic member may move the dust box compression rod 223 and the compression member (not shown) upward.

[0184] A compression member (not shown) may be provided inside the dust box body 221. The compression member may move in the internal space of the dust box body 221. Specifically, the compression member may move upward and downward in the dust box body 221. Therefore, the compression member may compress the dust in the dust box body 221 downward. In addition, when the discharge cover 222 is separated from the dust box body 221 and thus the lower side of the dust box 220 is opened, the compression member may move from the upper side of the dust box 220 to the lower side of the dust box 220, thereby removing foreign matter such as residual dust in the dust box 220. Therefore, the suction force of the cleaner may be improved by preventing the residual dust from remaining in the dust box 220. In addition, by preventing the residual dust from remaining in the dust box 220, unpleasant odors caused by the residual dust may be removed.

[0185] The first cleaner 200 may include a battery housing 230. The battery 240 may be accommodated in the battery housing 230. The battery housing 230 may be disposed on the lower side of the handle 216. For example, the battery housing 230 may have a hexahedral shape opened on its lower side. The rear surface of the battery housing 230 may be connected to the handle 216.

[0186] The battery case 230 may include a receiving portion opened at a lower side thereof. The battery 240 may be attached or detached through the receiving portion of the battery case 230.

[0187] The first cleaner 200 may include a battery 240 .

[0188] For example, the battery 240 may be detachably coupled to the first cleaner 200. The battery 240 may be detachably coupled to the battery housing 230. For example, the battery 240 may be inserted into the battery housing 230 from a lower side thereof.

[0189] In addition, the battery 240 may be integrally provided in the battery case 230. In this case, the lower surface of the battery 240 is not exposed to the outside.

[0190] The battery 240 can supply power to the suction motor 214 of the first cleaner 200. The battery 240 can be arranged at the lower part of the handle 216. The battery 240 can be arranged at the rear side of the dust box 220. That is, the suction motor 214 and the battery 240 can be arranged not to overlap each other in the upward / downward direction, and to be arranged at different arrangement heights. Based on the handle 216, the heavier suction motor 214 is arranged at the front side of the handle 216, and the heavier battery 240 is arranged at the lower side of the handle 216, so that the total weight of the first cleaner 200 can be evenly distributed. Therefore, when the user grasps the handle 216 and performs a cleaning operation, stress can be prevented from being applied to the user's wrist.

[0191] In the case where the battery 240 according to the present embodiment is coupled to the battery housing 230, the lower surface of the battery 240 may be exposed to the outside. Since the battery 240 may be placed on the floor when the first cleaner 200 is placed on the floor, the battery 240 may be immediately separated from the battery housing 230. In addition, since the lower surface of the battery 240 is exposed to the outside and thus directly contacts the air outside the battery 240, the performance of cooling the battery 240 may be improved.

[0192] Meanwhile, when the battery 240 is integrally fixed to the battery case 230 , the number of structures for attaching or detaching the battery 240 and the battery case 230 can be reduced, and as a result, the overall size and weight of the first cleaner 200 can be reduced.

[0193] The first cleaner 200 may include an extension pipe 250. The extension pipe 250 may be in communication with the cleaning module 260. The extension pipe 250 may be in communication with the body 210. The extension pipe 250 may be in communication with the suction portion 212 of the body 210. The extension pipe 250 may be formed in an elongated cylindrical shape.

[0194] The main body 210 may be connected to the extension pipe 250. The main body 210 may be connected to the cleaning module 260 through the extension pipe 250. The main body 210 may generate suction through the suction motor 214 and provide suction to the cleaning module 260 through the extension pipe 250. External dust may be introduced into the main body 210 through the cleaning module 260 and the extension pipe 250.

[0195] The first cleaner 200 may include a cleaning module 260. The cleaning module 260 may communicate with the extension pipe 250. Therefore, external air may be introduced into the body 210 of the first cleaner 200 via the cleaning module 260 and the extension pipe 250 by suction generated in the body 210 of the first cleaner 200.

[0196] The dust in the dust box 220 of the first cleaner 200 can be captured by the dust collecting part 170 of the cleaner station 100 by the gravity and suction of the dust collecting motor 191. Therefore, the dust in the dust box can be removed without the need for a separate operation by the user, thereby providing convenience for the user. In addition, the inconvenience caused by the user needing to always empty the dust box can be eliminated. In addition, when the dust box is emptied, dust can be prevented from being scattered.

[0197] The first cleaner 200 may be coupled to the side surface of the housing 110. Specifically, the main body 210 of the first cleaner 200 may be mounted on the coupling portion 120. More specifically, the dust box 220 and the battery housing 230 of the first cleaner 200 may be coupled to the coupling surface 121, the outer peripheral surface of the dust box main body 221 may be coupled to the dust box guide surface 122, and the suction portion 212 may be coupled to the suction portion guide surface 126 of the coupling portion 120 (see Figure 2 ).

[0198] Meanwhile, in the present embodiment, the imaginary center of gravity plane S1 may be defined and include at least two of the motor axis a1, the suction flow path center line a2, the handle axis a3, the cyclone center axis a4, and the dust box axis a5. That is, the center of gravity plane S1 may be an imaginary plane formed by connecting two imaginary lines, and includes an imaginary plane formed by extending an imaginary plane.

[0199] For example, the center of gravity plane S1 may include the motor axis a1 and the suction flow path center line a2. Alternatively, the center of gravity plane S1 may include the motor axis a1 and the handle axis a3. Alternatively, the center of gravity plane S1 may include the cyclone center axis a4 and the suction flow path center line a2. Alternatively, the center of gravity plane S1 may include the cyclone center axis a4 and the handle axis a3. Alternatively, the center of gravity plane S1 may include the dust box axis a5 and the suction flow path center line a2. Alternatively, the center of gravity plane S1 may include the dust box axis a5 and the handle axis a3. Alternatively, the center of gravity plane S1 may include the suction flow path center line a2 and the handle axis a3.

[0200] Therefore, the suction part 212 may be disposed on an imaginary extension plane of the center of gravity plane S1. Alternatively, the dust separation part 213 may be disposed on an imaginary extension plane of the center of gravity plane S1. Alternatively, the suction motor 214 may be disposed on an imaginary extension plane of the center of gravity plane S1. Alternatively, the handle 216 may be disposed on an imaginary extension plane of the center of gravity plane S1. Alternatively, the dust box 220 may be disposed on an imaginary extension plane of the center of gravity plane S1.

[0201] Through this configuration, the center of gravity of the entire first cleaner 200 can be symmetrically disposed with respect to the center-of-gravity plane S1.

[0202] The dust removal system 10 may include a second cleaner 300. The second cleaner 300 may refer to a robot cleaner. When the second cleaner 300 autonomously travels in the area to be cleaned, the second cleaner 300 may automatically clean the area to be cleaned by sucking foreign matter such as dust from the floor. The second cleaner 300 (i.e., the robot cleaner) may include a distance sensor and a left wheel and a right wheel for moving the robot cleaner, and the distance sensor is configured to detect the distance from obstacles (such as furniture, office supplies or walls) installed in the area to be cleaned. The second cleaner 300 may be coupled to a cleaner station. The dust in the second cleaner 300 may be captured in the dust collecting portion 170 by a second flow path (not shown).

[0203] at the same time, Fig.15 is a view for explaining an arrangement relationship between a cleaner station and a center of gravity of a first cleaner according to an embodiment of the present disclosure, and Fig.16 It shows that when viewed from another direction Fig.15 Schematic view of the time.

[0204] The following will refer to Figure 1 , Figure 2 , Fig.15 and Fig.16 A cleaner station 100 according to the present disclosure is described.

[0205] The first cleaner 200 and the second cleaner 300 may be disposed on the cleaner station 100. The first cleaner 200 may be coupled to a side surface of the cleaner station 100. Specifically, a main body of the first cleaner 200 may be coupled to a side surface of the cleaner station 100. The second cleaner 300 may be coupled to a lower portion of the cleaner station 100. The cleaner station 100 may remove dust from the dust box 220 of the first cleaner 200. The cleaner station 100 may remove dust from a dust box (not shown) of the second cleaner 300.

[0206] The cleaner station 100 may include a housing 110. The housing 110 may define the appearance of the cleaner station 100. Specifically, the housing 110 may be formed in the form of a column including one or more outer wall surfaces. For example, the housing 110 may be formed in a shape similar to a quadrilateral column.

[0207] The housing 110 may have a space capable of accommodating the dust collecting portion 170 configured to store dust therein and the dust suction module 190 configured to generate a flow force for collecting dust from the dust collecting portion 170 .

[0208] The housing 110 may include a bottom surface 111 and an outer wall surface 112 .

[0209] The bottom surface 111 may support the lower side of the dust suction module 190 in the gravity direction. That is, the bottom surface 111 may support the lower side of the dust collecting motor 191 of the dust suction module 190.

[0210] In this case, the bottom surface 111 can be arranged toward the ground. The bottom surface 111 can also be arranged to be parallel to the ground, or to be arranged to be inclined at a predetermined angle relative to the ground. Even when the first cleaner 200 is connected, the above configuration is advantageous in stably supporting the dust collecting motor 191 and maintaining the balance of the total weight.

[0211] Meanwhile, according to this embodiment, the bottom surface 111 may further include a ground support portion (not shown) to prevent the cleaner station 100 from falling and increase the area in contact with the ground to maintain balance. For example, the ground support portion may have a plate shape extending from the bottom surface 111, and one or more frames may protrude and extend from the bottom surface 111 in the direction of the ground. In this case, the ground support portion may be arranged to be linearly symmetrical so as to maintain left-right balance and front-back balance based on the front surface on which the first cleaner 200 is installed.

[0212] The outer wall surface 112 may refer to a surface formed in the gravity direction or a surface connected to the bottom surface 111. For example, the outer wall surface 112 may refer to a surface connected to the bottom surface 111 so as to be perpendicular to the bottom surface 111. As another embodiment, the outer wall surface 112 may be provided to be inclined at a predetermined angle relative to the bottom surface 111.

[0213] The outer wall surface 112 may include at least one surface. For example, the outer wall surface 112 may include a first outer wall surface 112a, a second outer wall surface 112b, a third outer wall surface 112c, and a fourth outer wall surface 112d.

[0214] In this case, in the present embodiment, the first outer wall surface 112a may be provided at the front side of the cleaner station 100. In this case, the front side may refer to a side to which the first cleaner 200 or the second cleaner 300 is coupled. Therefore, the first outer wall surface 112a may define the appearance of the front surface of the cleaner station 100.

[0215] Meanwhile, directions are defined as follows to understand the present embodiment: In the present embodiment, directions may be defined in a state in which the first cleaner 200 is mounted on the cleaner station 100 .

[0216] In this case, the surface including the extension line 212a of the suction portion 212 may be referred to as the front surface (see Figure 1). That is, in a state where the first cleaner 200 is installed on the cleaner station 100, a portion of the suction portion 212 may be in contact with and coupled to the suction portion guide surface 126, and the remaining portion of the suction portion 212 that is not coupled to the suction portion guide surface 126 may be arranged to be exposed to the outside from the first outer wall surface 112a. Therefore, an imaginary extension line 212a of the suction portion 212 may be set on the first outer wall surface 112a, and a surface including the extension line 212a of the suction portion 212 may be referred to as a front surface.

[0217] On the other hand, in a state in which the rod pulling arm 161 is coupled to the housing 110 , a surface including a side through which the rod pulling arm 161 is exposed to the outside may be referred to as a front surface.

[0218] On the other hand, in a state in which the first cleaner 200 is mounted on the cleaner station 100 , an outer surface of the cleaner station 100 penetrated by the main body 210 of the first cleaner may be referred to as a front surface.

[0219] In addition, in a state in which the first cleaner 200 is mounted on the cleaner station 100 , a direction in which the first cleaner 200 is exposed to the outside of the cleaner station 100 may be referred to as a forward direction.

[0220] In addition, on the other hand, in a state where the first cleaner 200 is installed on the cleaner station 100, the direction in which the suction motor 214 of the first cleaner 200 is arranged may be referred to as a forward direction. In addition, the direction opposite to the direction in which the suction motor 214 is arranged on the cleaner station 100 may be referred to as a backward direction.

[0221] On the other hand, the direction in which the intersection point where the handle axis a3 and the motor axis a1 intersect may be referred to as a forward direction based on the cleaner station 100. Alternatively, the direction in which the intersection point where the handle axis a3 and the suction flow path centerline a2 intersect may be referred to as a forward direction. Alternatively, the direction in which the intersection point where the motor axis a1 and the suction flow path centerline a2 intersect may be referred to as a forward direction. In addition, based on the cleaner station 100, the direction opposite to the direction in which the intersection point is set may be referred to as a backward direction.

[0222] In addition, based on the inner space of the coupling portion 120 and the housing 110, the surface facing the front surface may be referred to as a rear surface of the cleaner station 100. Therefore, the rear surface may refer to a direction in which the second outer wall surface 112b is formed.

[0223] In addition, based on the internal space of the housing 110, the left surface when the front surface is viewed may be referred to as the left surface, and the right surface when the front surface is viewed may be referred to as the right surface. Therefore, the left surface may refer to the direction in which the third outer wall surface 112c is formed, and the right surface may refer to the direction in which the fourth outer wall surface 112d is formed.

[0224] The first outer wall surface 112 a may be formed in the form of a flat surface, or the first outer wall surface 112 a may be formed in the form of a curved surface as a whole, or may be formed to partially include a curved surface.

[0225] The first outer wall surface 112a may have an appearance corresponding to the shape of the first cleaner 200. In detail, the coupling portion 120 may be provided on the first outer wall surface 112a. Through this configuration, the first cleaner 200 may be coupled to the cleaner station 100 and supported by the cleaner station 100. The specific configuration of the coupling portion 120 will be described below.

[0226] In addition, the rod pulling unit 160 may be provided on the first outer wall surface 112a. Specifically, the rod pulling arm 161 of the rod pulling unit 160 may be mounted on the first outer wall surface 112a. For example, the first outer wall surface 112a may have an arm receiving groove in which the rod pulling arm 161 may be received. In this case, the arm receiving groove may be formed to correspond to the shape of the rod pulling arm 161. Therefore, when the rod pulling arm 161 is mounted in the arm receiving groove, the first outer wall surface 112a and the outer surface of the rod pulling arm 161 may define a continuous outer shape, and the rod pulling arm 161 may be moved by the operation of the rod pulling unit 160 to protrude from the first outer wall surface 112a.

[0227] Meanwhile, a structure for installing various types of cleaning modules 260 for the first cleaner 200 may be additionally provided on the first outer wall surface 112 a .

[0228] Furthermore, a structure to which the second cleaner 300 can be coupled may be additionally provided on the first outer wall surface 112a. Therefore, a structure corresponding to the shape of the second cleaner 300 may be additionally provided on the first outer wall surface 112a.

[0229] Furthermore, a cleaner bottom plate (not shown) to which the lower surface of the second cleaner 300 may be coupled may be additionally coupled to the first outer wall surface 112a. Meanwhile, as another embodiment, the cleaner bottom plate (not shown) may be shaped to be connected to the bottom surface 111.

[0230] In the present embodiment, the second outer wall surface 112b may be a surface facing the first outer wall surface 112a. That is, the second outer wall surface 112b may be provided on the rear surface of the cleaner station 100. In this case, the rear surface may be a surface facing the surface to which the first cleaner 200 or the second cleaner 300 is coupled. Therefore, the second outer wall surface 112b may define the appearance of the rear surface of the cleaner station 100.

[0231] For example, the second outer wall surface 112b may be formed in the form of a flat surface. Through this configuration, the cleaner station 100 may be in close contact with a wall in a room, and the cleaner station 100 may be stably supported.

[0232] As another example, a structure for installing various types of cleaning modules 260 for the first cleaner 200 may be additionally provided on the second outer wall surface 112 b .

[0233] Furthermore, a structure to which the second cleaner 300 may be coupled may be additionally provided on the second outer wall surface 112b. Therefore, a structure corresponding to the shape of the second cleaner 300 may be additionally provided on the second outer wall surface 112b.

[0234] In addition, a cleaner base plate (not shown) to which the lower surface of the second cleaner 300 can be coupled can be additionally coupled to the second outer wall surface 112b. Meanwhile, as another embodiment, the cleaner base plate (not shown) can be formed to be connected to the bottom surface 111. By this configuration, when the second cleaner 300 is coupled to the cleaner base plate (not shown), the overall center of gravity of the cleaner station 100 can be lowered, so that the cleaner station 100 can be stably supported.

[0235] In the present embodiment, the third outer wall surface 112c and the fourth outer wall surface 112d may refer to surfaces connecting the first outer wall surface 112a and the second outer wall surface 112b. In this case, the third outer wall surface 112c may be provided on the left surface of the cleaner station 100, and the fourth outer wall surface 112d may be provided on the right surface of the cleaner station 100. In addition, the third outer wall surface 112c may be provided on the right surface of the cleaner station 100, and the fourth outer wall surface 112d may be provided on the left surface of the cleaner station 100.

[0236] The third outer wall surface 112c or the fourth outer wall surface 112d may be formed in the form of a flat surface, or the third outer wall surface 112c or the fourth outer wall surface 112d may be formed in the form of a curved surface as a whole or formed to partially include a curved surface.

[0237] Meanwhile, a structure for installing various types of cleaning modules 260 for the first cleaner 200 may be additionally provided on the third outer wall surface 112 c or the fourth outer wall surface 112 d .

[0238] Furthermore, a structure to which the second cleaner 300 can be coupled can be additionally provided on the third outer wall surface 112c or the fourth outer wall surface 112d. Therefore, a structure corresponding to the shape of the second cleaner 300 can be additionally provided on the third outer wall surface 112c or the fourth outer wall surface 112d.

[0239] In addition, a cleaner bottom plate (not shown) to which the lower surface of the second cleaner 300 can be coupled can be additionally provided on the third outer wall surface 112c or the fourth outer wall surface 112d. Meanwhile, as another embodiment, the cleaner bottom plate (not shown) can be formed to be connected to the bottom surface 111.

[0240] Figure 5 is a view for explaining a coupling portion of a cleaner station according to an embodiment of the present disclosure, and Figure 6 1 is a view for explaining the arrangement of a fixing unit, a door unit, a cover opening unit, and a rod pulling unit in a cleaner station according to an embodiment of the present disclosure.

[0241] The following will refer to Figure 5 and Figure 6 The coupling portion 120 of the cleaner station 100 according to the present disclosure is described.

[0242] The cleaner station 100 may include a coupling portion 120 to which the first cleaner 200 is coupled. Specifically, the coupling portion 120 may be provided in the first outer wall surface 112a, and the body 210, the dust box 220, and the battery housing 230 of the first cleaner 200 may be coupled to the coupling portion 120.

[0243] The coupling portion 120 may include a coupling surface 121. The coupling surface 121 may be provided on a side surface of the housing 110. For example, the coupling surface 121 may refer to a surface formed in the form of a groove that is recessed from the first outer wall surface 112a toward the inside of the cleaner station 100. That is, the coupling surface 121 may refer to a surface formed to have a step portion relative to the first outer wall surface 112a.

[0244] The first cleaner 200 may be coupled to the coupling surface 121. For example, the coupling surface 121 may contact the lower surface of the dust box 220 of the first cleaner 200 and the lower surface of the battery housing 230. In this case, the lower surface may refer to a surface facing the ground when the user uses the first cleaner 200 or places the first cleaner 200 on the ground.

[0245] In this case, the coupling surface 121 and the dust box 220 of the first cleaner 200 may mean a physical coupling by which the first cleaner 200 and the cleaner station 100 are coupled and fixed to each other. This may be a prerequisite for the coupling of the dust box 220 and the flow path portion 180 to each other and the flow path through which the fluid can flow.

[0246] In addition, the coupling between the coupling surface 121 and the battery housing 230 of the first cleaner 200 may refer to a physical coupling by which the first cleaner 200 and the cleaner station 100 are coupled and fixed to each other. This may be a prerequisite for the electrical coupling by which the battery 240 and the charging part 128 are electrically connected to each other.

[0247] For example, the angle of the coupling surface 121 with respect to the ground may be a right angle. Therefore, when the first cleaner 200 is coupled to the coupling surface 121, the space of the cleaner station 100 may be minimized.

[0248] As another example, the coupling surface 121 may be provided to be inclined at a predetermined angle with respect to the ground. Therefore, when the first cleaner 200 is coupled to the coupling surface 121, the cleaner station 100 may be stably supported.

[0249] The coupling surface 121 may have a dust passage hole 121a through which air outside the housing 110 may be introduced into the housing 110. The dust passage hole 121a may be formed in the form of a hole corresponding to the shape of the dust box 220 so that dust in the dust box 220 may be introduced into the dust collecting portion 170. The dust passage hole 121a may be formed to correspond to the shape of the discharge cover 222 of the dust box 220. The dust passage hole 121a may be formed to communicate with a first flow path 181 to be described below.

[0250] The coupling portion 120 may include a dust box guide surface 122. The dust box guide surface 122 may be provided on the first outer wall surface 112a. The dust box guide surface 122 may be connected to the first outer wall surface 112a. In addition, the dust box guide surface 122 may be connected to the coupling surface 121.

[0251] The dust box guide surface 122 may be formed in a shape corresponding to the outer surface of the dust box 220. The front outer surface of the dust box 220 may be coupled to the dust box guide surface 122. Therefore, when the first cleaner 200 is coupled to the coupling surface 121, convenience may be provided.

[0252] The coupling portion 120 may include a guide protrusion 123. The guide protrusion 123 may be provided on the coupling surface 121. The guide protrusion 123 may protrude upward from the coupling surface 121. Two guide protrusions 123 may be provided to be spaced apart from each other. The distance between the two guide protrusions 123 spaced apart from each other may correspond to the width of the battery housing 230 of the first cleaner 200. Therefore, when the first cleaner 200 is coupled to the coupling surface 121, convenience may be provided.

[0253] The coupling portion 120 may include a side wall 124. The side wall 124 may refer to a wall surface provided on both side surfaces of the coupling surface 121, and may be vertically connected to the coupling surface 121. The side wall 124 may be connected to the first outer wall surface 112a. In addition, the side wall 124 may be connected to the dust box guide surface 122. That is, the side wall 124 may define a surface connected to the dust box guide surface 122. Therefore, the first cleaner 200 may be stably accommodated.

[0254] The coupling portion 120 may include a coupling sensor 125. The coupling sensor 125 may detect whether the first cleaner 200 is coupled to the coupling portion 120.

[0255] The connection sensor 125 may include a contact sensor. For example, the connection sensor 125 may include a micro switch. In this case, the connection sensor 125 may be provided on the guide protrusion 123. Therefore, when the battery housing 230 or the battery 240 of the first cleaner 200 is connected between a pair of guide protrusions 123, the battery housing 230 or the battery 240 contacts the connection sensor 125, so that the connection sensor 125 can detect that the first cleaner 200 is physically connected to the cleaner station 100.

[0256] Meanwhile, the coupling sensor 125 may include a non-contact sensor. For example, the coupling sensor 125 may include an infrared (IR) sensor. In this case, the coupling sensor 125 may be disposed on the sidewall 124. Therefore, when the dust box 220 or the main body 210 of the first cleaner 200 passes through the sidewall 124 and then reaches the coupling surface 121, the coupling sensor 125 may detect the presence of the dust box 220 or the main body 210, and detect that the first cleaner 200 is physically coupled to the cleaner station 100.

[0257] Meanwhile, the coupling sensor 125 may be further provided on the dust box guide surface 122. In this case, the coupling sensor 125 may include a contact sensor. Therefore, when the first cleaner is coupled, the dust box 220 may push the coupling sensor 125 by the weight of the dust box 220, and the coupling sensor 125 may detect that the first cleaner 200 is coupled.

[0258] The coupling sensor 125 may face the dust box 220 or the battery case 230 of the first cleaner 200 .

[0259] The coupling sensor 125 may be a device for determining whether the first cleaner 200 is coupled and whether to supply power to the battery 240 of the first cleaner 200 .

[0260] The coupling portion 120 may include a suction portion guide surface 126. The suction portion guide surface 126 may be provided on the first outer wall surface 112a. The suction portion guide surface 126 may be connected to the dust box guide surface 122. The suction portion 212 may be coupled to the suction portion guide surface 126. The suction portion guide surface 126 may be formed in a shape corresponding to the shape of the suction portion 212. Therefore, when the main body 210 of the first cleaner 200 is coupled to the coupling surface 121, convenience may be provided.

[0261] The coupling portion 120 may include a fixing member entry hole 127. The fixing member entry hole 127 may be formed in the form of a long hole along the side wall 124 so that the fixing member 131 may enter and leave the fixing member entry hole 127. For example, the fixing member entry hole 127 may be a rectangular hole formed along the side wall 124. The fixing member 131 will be described in detail below.

[0262] By this configuration, when the user couples the first cleaner 200 to the coupling portion 120 of the cleaner station 100, the body 210 of the first cleaner 200 can be stably disposed on the coupling portion 120 by the first guide portion 122, the second guide portion 123, and the third guide portion 126. Therefore, when the dust box 220 and the battery housing 230 of the first cleaner 200 are coupled to the coupling surface 121, convenience can be provided.

[0263] at the same time, Figure 7 is an exploded perspective view for explaining a fixing unit of a cleaner station according to an embodiment of the present disclosure, Figure 8 is a view for explaining the arrangement of a fixing unit in a first cleaner and a cleaner station according to an embodiment of the present disclosure, and Fig. 9 is a cross-sectional view for explaining a fixing unit of a cleaner station according to an embodiment of the present disclosure.

[0264] The following will refer to Figures 5 to 9 The fixing unit 130 according to the present disclosure is described.

[0265] The cleaner station 100 according to the present disclosure may include a fixing unit 130. The fixing unit 130 may be provided on the side wall 124. In addition, the fixing unit 130 may be provided on the back side of the coupling surface 121. The fixing unit 130 may fix the first cleaner 200 coupled to the coupling surface 121. Specifically, the fixing unit 130 may fix the dust box 220 and the battery housing 230 of the first cleaner 200 coupled to the coupling surface 121.

[0266] The fixing unit 130 may include: a fixing member 131 configured to fix the dust box 220 and the battery housing 230 of the first cleaner 200; and a fixing part motor 133 configured to operate the fixing member 131. In addition, the fixing unit 130 may further include: a fixing part gear 134 configured to transmit power from the fixing part motor 133 to the fixing member 131; and a fixing part connecting rod 135 configured to convert the rotational motion of the fixing part gear 134 into the reciprocating motion of the fixing member 131. In addition, the fixing unit 130 may further include: a fixing part housing 132 configured to accommodate the fixing part motor 133 and the fixing part gear 134.

[0267] The fixing member 131 may be provided on the side wall 124 of the coupling portion 120 and provided on the side wall 124 to reciprocate, thereby fixing the dust box 220. Specifically, the fixing member 131 may be received in the fixing member entry hole 127.

[0268] The fixing members 131 may be respectively disposed at both sides of the coupling portion 120. For example, a pair of two fixing members 131 may be symmetrically disposed with respect to the coupling surface 121.

[0269] Specifically, the fixing member 131 may include a link coupling portion 131a, a movable panel 131b, and a movable seal 131c. In this case, the link coupling portion 131a may be provided on one side of the movable panel 131b, and the movable seal 131c may be provided on the other side of the movable panel 131b.

[0270] The link coupling part 131a is provided at one side of the movable panel 131b and coupled to the fixed part link 135. For example, the link coupling part 131a may protrude from a connecting protrusion 131bb formed by bending and extending one end of the movable panel 131b in a cylindrical or round pin shape. Therefore, the link coupling part 131a may be rotatably inserted and coupled to one end of the fixed part link 135.

[0271] The movable panel 131b may be connected to the link coupling portion 131a and configured to be reciprocatingly movable from the side wall 124 toward the dust box 220 by operation of the fixed portion motor 133. For example, the movable panel 131b may be configured to be linearly and reciprocatingly movable along the guide frame 131d.

[0272] Specifically, one side of the movable panel 131 b may be disposed to be accommodated in the space in the first outer wall surface 112 a , and the other side of the movable panel 131 b may be disposed to be exposed from the side wall 124 .

[0273] The movable panel 131b may include a panel body 131ba, a connecting protrusion 131bb, a first pressing portion 131bc, and a second pressing portion 131bd. For example, the panel body 131ba may be formed in the form of a flat plate. In addition, the connecting protrusion 131bb may be provided at one end of the panel body 131ba. In addition, the first pressing portion 131bc may be formed at the other end of the panel body 131ba.

[0274] The connection protrusion 131bb may be formed by bending and extending one end of the panel body 131ba toward the fixing portion motor 133. The link coupling portion 131a may protrude and extend from a distal end of the connection protrusion 131bb.

[0275] The connection protrusion 131bb may have a frame through-hole through which the guide frame 131d may penetrate. For example, the frame through-hole may be formed in a shape similar to an "I" shape.

[0276] The first pressing portion 131bc is formed at the other end of the panel body 131ba and is formed in a shape corresponding to the shape of the dust box 220 so as to seal the dust box 220. For example, the first pressing portion 131bc may be formed in a shape capable of surrounding a cylindrical shape. That is, the first pressing portion 131bc may refer to an end portion having a concave arc shape and formed on the other side of the panel body 131ba.

[0277] The second pressing portion 131bd may be connected to the first pressing portion 131bc and formed in a shape corresponding to the shape of the battery case 230 so as to seal the battery case 230. For example, the second pressing portion 131bd may be formed in a shape capable of pressing the battery case 230. That is, the second pressing portion 131bd may refer to an end portion having a straight line shape and formed on the other side of the panel body 131ba.

[0278] The movable seal 131c may be provided on the end in the reciprocating direction of the movable panel 131b, and may seal the dust box 220. Specifically, the movable seal 131c may be coupled to the first pressing portion 131bc, and may seal the space between the dust box 220 and the first pressing portion 131bc when the first pressing portion 131bc surrounds and presses the dust box 220. In addition, the movable seal 131c may be coupled to the second pressing portion 131bd, and may seal the space between the battery case 230 and the second pressing portion 131bd when the second pressing portion 131bd surrounds and presses the battery case 230.

[0279] The fixing unit 130 may further include a guide frame 131d coupled to the housing 110 and configured to penetrate the movable panel 131b and guide the movement of the fixing member 131. For example, the guide frame 131d may be an "I"-shaped frame having a penetrating connection protrusion 131bb. With this configuration, the movable panel 131b may reciprocate linearly along the guide frame 131d.

[0280] The fixing portion housing 132 may be provided in the housing 110. For example, the fixing portion housing 132 may be provided on the back side of the coupling surface 121.

[0281] The fixed part housing 132 may have therein a space capable of accommodating the fixed part gear 134. In addition, the fixed part housing 132 may accommodate the fixed part motor 133.

[0282] The fixing portion housing 132 may include a first fixing portion housing 132 a , a second fixing portion housing 132 b , a connecting rod guide hole 132 c , and a motor accommodation portion 132 d .

[0283] The first and second fixing portion cases 132 a and 132 b are coupled to each other to define a space capable of accommodating the fixing portion gear 134 therein.

[0284] For example, the first fixing portion housing 132a may be disposed in a direction toward the outside of the cleaner station 100, and the second fixing portion housing 132b may be disposed in a direction toward the inside of the cleaner station 100. That is, the first fixing portion housing 132a may be disposed in a direction toward the coupling surface 121, and the second fixing portion housing 132b may be disposed in a direction toward the second outer wall surface 112b.

[0285] The connecting rod guide hole 132c may be formed in the first fixing part housing 132a. The connecting rod guide hole 132c may refer to a hole formed to guide the moving route of the fixing part connecting rod 135. For example, the connecting rod guide hole 132c may refer to an arc hole formed in a circumferential direction around the rotation axis of the fixing part gear 134.

[0286] Two link guide holes 132c may be formed to guide the pair of fixing portion links 135 for moving the pair of fixing members 131. In addition, the two link guide holes 132c may be symmetrically formed.

[0287] The motor accommodation portion 132d may be provided to accommodate the fixing portion motor 133. For example, the motor accommodation portion 132d may protrude from the first fixing portion housing 132a in a cylindrical shape so as to accommodate the fixing portion motor 133 therein.

[0288] The fixing part motor 133 may provide power for moving the fixing member 131. Specifically, the fixing part motor 133 may rotate the fixing part gear 134 in a forward direction or a reverse direction. In this case, the forward direction may refer to a direction in which the fixing member 131 moves from the side wall 124 to press the dust box 220. In addition, the reverse direction may refer to a direction in which the fixing member 131 moves from a position in which the fixing member 131 presses the dust box 220 to the inner side of the side wall 124. The forward direction may be opposite to the reverse direction.

[0289] The fixing section gear 134 may be coupled to the fixing section motor 133 and may move the fixing member 131 using power from the fixing section motor 133 .

[0290] The fixing portion gear 134 may include a driving gear 134 a , a connecting gear 134 b , a first link rotating gear 134 c , and a second link rotating gear 134 d .

[0291] The shaft of the fixed portion motor 133 may be inserted and coupled to the driving gear 134a. For example, the shaft of the fixed portion motor 133 may be inserted and fixedly coupled to the driving gear 134a. As another example, the driving gear 134a may be integrally formed with the shaft of the fixed portion motor 133.

[0292] The connecting gear 134b may be engaged with the driving gear 134a and the first link rotating gear 134c.

[0293] The other end of the fixing portion link 135 is rotatably coupled to the first link rotating gear 134 c , and the first link rotating gear 134 c may transfer the rotating force transferred from the driving gear 134 a to the fixing portion link 135 .

[0294] The first link rotating gear 134c may include a rotating shaft 134ca, a rotating surface 134cb, gear teeth 134cc, and a link fastening portion 134cd.

[0295] The rotating shaft 134ca can be coupled to and supported by the first fixed part housing 132a and the second fixed part housing 132b. The rotating surface 134cb can be formed in a circular plate shape having a predetermined thickness around the rotating shaft 134ca. Gear teeth 134cc can be formed on the outer peripheral surface of the rotating surface 134cb and can be engaged with the connecting gear 134b. In addition, the gear teeth 134cc can be engaged with the second connecting rod rotating gear 134d. Through this configuration, the first connecting rod rotating gear 134c can receive power from the fixed part motor 133 through the driving gear 134a and the connecting gear 134b, and transmit the power to the second connecting rod rotating gear 134d.

[0296] The connecting rod fastening portion 134cd may protrude and extend in a cylindrical or circular pin shape from the rotating surface 134cb in the axial direction. The connecting rod fastening portion 134cd may be rotatably coupled to the other end of the fixed portion connecting rod 135. For example, the connecting rod fastening portion 134cd may penetrate the connecting rod guide hole 132c and may be coupled to the other end of the fixed portion connecting rod 135. By this configuration, the first connecting rod rotating gear 134c may be rotated by the power from the fixed portion motor 133, and the fixed portion connecting rod 135 may be rotated and linearly moved by the rotation of the first connecting rod rotating gear 134c, and therefore, the fixing member 131 may be moved to fix or release the dust box 220.

[0297] The second link rotating gear 134d may be engaged with the first link rotating gear 134c and rotated in a direction opposite to the rotation direction of the first link rotating gear 134c.

[0298] The other end of the fixing portion link 135 is rotatably coupled to the second link rotating gear 134 d , and the second link rotating gear 134 d may transmit the rotating force transmitted from the driving gear 134 a to the fixing portion link 135 .

[0299] The second link rotating gear 134 d may include a rotating shaft 134 da , a rotating surface 134 db , gear teeth 134 dc , and a link fastening portion 134 dd .

[0300] The rotating shaft 134da may be coupled to and supported by the first fixed part housing 132a and the second fixed part housing 132b. The rotating surface 134db may be formed in a circular plate shape having a predetermined thickness around the rotating shaft 134da. Gear teeth 134dc may be formed on the outer peripheral surface of the rotating surface 134db and may engage with the first connecting rod rotating gear 134c. With this configuration, the second connecting rod rotating gear 134d may receive power from the fixed part motor 133 through the driving gear 134a, the connecting gear 134b and the first connecting rod rotating gear 134c.

[0301] The connecting rod fastening portion 134dd may protrude and extend in a cylindrical or circular pin shape from the rotating surface 134db in the axial direction. The connecting rod fastening portion 134dd may be rotatably coupled to the other end of the fixed portion connecting rod 135. For example, the connecting rod fastening portion 134dd may penetrate the connecting rod guide hole 132c and may be coupled to the other end of the fixed portion connecting rod 135. By this configuration, the second connecting rod rotating gear 134d may be rotated by the power from the fixed portion motor 133, and the fixed portion connecting rod 135 may be rotated and linearly moved by the rotation of the second connecting rod rotating gear 134d, and therefore, the fixing member 131 may be moved to fix or release the dust box 220.

[0302] The fixing portion link 135 may connect the fixing portion gear 134 and the fixing member 131 and convert the rotation of the fixing portion gear 134 into the reciprocating motion of the fixing member 131 .

[0303] One end of the fixing portion link 135 may be coupled to the link coupling portion 131 a of the fixing member 131 , and the other end of the fixing portion link 135 may be coupled to the link fastening portion 134 cd or 134 dd of the fixing portion gear 134 .

[0304] The fixing portion link 135 may include a link body 135 a , a first link connection portion 135 b , and a second link connection portion 135 c .

[0305] For example, the connecting rod body 135a may be formed in the form of a frame having a curved central portion. This is to improve the efficiency of transmitting power by changing the angle of transmitting force.

[0306] The first connecting rod connecting portion 135b may be provided at one end of the connecting rod body 135a, and the second connecting rod connecting portion 135c may be provided at the other end of the connecting rod body 135a. The first connecting rod connecting portion 135b may protrude in a cylindrical shape from one end of the connecting rod body 135a. The first connecting rod connecting portion 135b may have a hole into which the connecting rod connecting portion 131a may be inserted and connected. The second connecting rod connecting portion 135c may protrude in a cylindrical shape from the other end of the connecting rod body 135a. In this case, the height of the protrusion of the second connecting rod connecting portion 135c may be greater than the height of the protrusion of the first connecting rod connecting portion 135b. This enables the connecting rod fastening portions 134cd and 134dd of the fixed part gear 134 to be accommodated in the connecting rod guide hole 132c and move along the connecting rod guide hole 132c, and supports the connecting rod fastening portions 134cd and 134dd when the connecting rod fastening portions 134cd and 134dd rotate. The second link connection portion 135c may have a hole into which the link fastening portion 134cd or 134dd may be inserted and coupled.

[0307] The stationary seal 136 may be provided on the dust box guide surface 122 so as to seal the dust box 220 when the first cleaner 200 is coupled. With this configuration, when the dust box 220 of the first cleaner 200 is coupled, the first cleaner 200 can press the stationary seal 136 by its own weight so that the dust box 220 and the dust box guide surface 122 can be sealed.

[0308] The stationary seal 136 may be disposed on an imaginary extension line of the movable seal 131c. With this configuration, when the fixed portion motor 133 operates and the fixed member 131 presses the dust box 220, the periphery of the dust box 220 at the same height may be sealed. That is, the stationary seal 136 and the movable seal 131c may seal the outer peripheral surface of the dust box 220 disposed on concentric circles.

[0309] According to the embodiment, the stationary seal 136 may be provided on the dust box guide surface 122 and formed in the form of a curved line corresponding to the arrangement of the cover opening unit 150 to be described below.

[0310] Therefore, when the body 210 of the first cleaner 200 is disposed on the coupling portion 120, the fixing unit 130 can fix the body 210 of the first cleaner 200. Specifically, when the coupling sensor 125 detects that the body 210 of the first cleaner 200 is coupled to the coupling portion 120 of the cleaner station 100, the fixing portion motor 133 can move the fixing member 131 to fix the body 210 of the first cleaner 200.

[0311] The fixing unit 130 may further include a fixing detection portion 137 capable of detecting movement of the fixing member 131 .

[0312] The fixing detection portion 137 may be provided in the housing 110 , and may detect whether the dust box 220 is fixed.

[0313] For example, the fixed detection parts 137 may be respectively provided at both ends in the rotation area of ​​the fixed part link 135. That is, in the rotation area of ​​the fixed part link 135, the first fixed detection part 137a may be provided at the end in the direction in which the fixed member 131 is pushed toward the dust box 220. In addition, in the rotation area of ​​the fixed part link 135, the second fixed detection part 137b may be provided at the end in the direction in which the fixed member 131 is away from the dust box 220. In addition, as another example, the fixed detection parts 137 may be respectively provided at both ends of the linear motion area of ​​the fixed member 131.

[0314] Therefore, when the fixing part link 135 moves to a predetermined position (hereinafter, also referred to as "dust box fixing position FP1") provided with the first fixing detection part 137a, or when the fixing member 131 moves linearly to the predetermined position, the fixing detection part 137 can detect the movement and send a signal indicating that the dust box 220 is fixed. In addition, when the fixing part link 135 moves to a predetermined position (hereinafter, also referred to as "dust box release position FP2") provided with the second fixing detection part 137b, or when the fixing member 131 moves linearly to the predetermined position, the fixing detection part 137 can detect the movement and send a signal indicating that the dust box 220 is released.

[0315] The fixing detection portion 137 may include a contact sensor. For example, the fixing detection portion 137 may include a micro switch.

[0316] Meanwhile, the fixing detection part 137 may include a non-contact sensor. For example, the fixing detection part 137 may include an infrared (IR) sensor.

[0317] A method of controlling the fixing unit 130 will be described below together with a description of the control unit 400 of the cleaner station 100 according to the present disclosure.

[0318] at the same time, Figure 9a Another embodiment of a stationary unit 1130 of a cleaner station according to the present disclosure is shown.

[0319] In order to avoid repeated description, the contents related to the fixing unit 130 according to the embodiment of the present disclosure may be used to describe other components except those specifically mentioned in the present embodiment.

[0320] In the present embodiment, the fixing member 1131 may fix the dust box 220 and the battery housing 230 through upward / downward linear motion of the fixing portion frame 1135 .

[0321] That is, when the fixing portion frame 1135 is linearly moved upward by operation of the fixing portion motor 1133 , the fixing member 1131 is moved toward the dust box 220 in the side wall 124 by being guided by the fixing portion frame 1135 .

[0322] In this case, the fixed detection parts 1137 may be respectively disposed at both ends in the moving area of ​​the fixed part frame 1135. That is, the first fixed detection part 1137a may be disposed at the upper end of the moving area of ​​the fixed part frame 1135. In addition, the second fixed detection part 1137b may be disposed at the lower end of the moving area of ​​the fixed part frame 1135.

[0323] Therefore, when the fixing part frame 1135 moves to a predetermined position (hereinafter, also referred to as "dust box fixing position FP1") where the first fixing detection part 1137a is provided, the sensor feeler bar 1135a protruding from the fixing part frame 1135 pushes the first fixing detection part 1137a, and the first fixing detection part 1137a can send a signal indicating that the dust box 220 is fixed. In addition, when the fixing part frame 1135 moves to a predetermined position (hereinafter, also referred to as "dust box release position FP2") where the second fixing detection part 1137b is provided, the sensor feeler bar 1135a pushes the second fixing detection part 1137b, and the second fixing detection part 1137b can send a signal indicating that the dust box 220 is released.

[0324] Therefore, the amount of vibration and impact that occurs when the discharge cover 222 of the main body 210 of the fixed first cleaner 200 is separated from the dust box 220 increases, and as a result, the efficiency of moving the dust stored in the dust box 220 to the dust collecting part 170 of the cleaner station 100 can be improved. That is, the suction force of the cleaner can be improved by preventing the residual dust from remaining in the dust box. In addition, by preventing the residual dust from remaining in the dust box, unpleasant odors caused by the residual dust can be removed.

[0325] at the same time, Fig.10 2 is a view for explaining a relationship between a first cleaner and a door unit in a cleaner station according to an embodiment of the present disclosure.

[0326] The following will refer to Figure 5 , Figure 6 and Fig.10 A door unit 140 according to the present disclosure is described.

[0327] The cleaner station 100 according to the present disclosure may include a door unit 140. The door unit 140 may be configured to open or close the dust passage hole 121a.

[0328] The door unit 140 may include a door 141 , a door motor 142 , and a door arm 143 .

[0329] The door 141 may be hingedly coupled to the coupling surface 121 and may open or close the dust passage hole 121a. The door 141 may include a door body 141a, a hinge portion 141b, and an arm coupling portion 141c.

[0330] The door body 141a may be formed into a shape capable of blocking the dust passage hole 121a. For example, the door body 141a may be formed into a shape similar to a circular plate shape. Based on the state in which the door body 141a blocks the dust passage hole 121a, the hinge portion 141b may be provided on the upper side of the door body 141a, and the arm coupling portion 141c may be provided on the lower side of the door body 141a.

[0331] The door body 141a may be formed into a shape capable of sealing the dust passage hole 121a. For example, the outer surface of the door body 141a exposed to the outside of the cleaner station 100 is formed to have a diameter corresponding to the diameter of the dust passage hole 121a, and the inner surface of the door body 141a provided in the cleaner station 100 is formed to have a diameter greater than the diameter of the dust passage hole 121a. In addition, a horizontal difference may be defined between the outer surface and the inner surface. At the same time, one or more reinforcing ribs may protrude from the inner surface to connect the hinge portion 141b and the arm coupling portion 141c, and strengthen the supporting force of the door body 141a.

[0332] The hinge portion 141b may be a device by which the door 141 is hingedly coupled to the coupling surface 121. The hinge portion 141b may be provided at an upper end of the door body 141a and coupled to the coupling surface 121.

[0333] The arm coupling portion 141c may be a device to which the door arm 143 may be rotatably coupled. The arm coupling portion 141c may be provided at a lower side of the inner surface, and the door arm 143 may be rotatably coupled to the arm coupling portion 141c.

[0334] By this configuration, when the door arm 143 pulls the door body 141a in a state where the door 141 closes the dust passage hole 121a, the door body 141a rotates around the hinge portion 141b toward the inside of the cleaner station 100 so that the dust passage hole 121a can be opened. At the same time, when the door arm 143 pushes the door body 141a in a state where the dust passage hole 121a is opened, the door body 141a rotates around the hinge portion 141b toward the outside of the cleaner station 100 so that the dust passage hole 121a can be closed.

[0335] The door motor 142 may provide power for rotating the door 141. Specifically, the door motor 142 may rotate the door arm 143 in a forward direction or a reverse direction. In this case, the forward direction may refer to the direction in which the door arm 143 pulls the door 141. Therefore, when the door arm 143 rotates in the forward direction, the dust passage hole 121a may be opened. In addition, the reverse direction may refer to the direction in which the door arm 143 pushes the door 141. Therefore, when the door arm 143 rotates in the reverse direction, at least a portion of the dust passage hole 121a may be closed. The forward direction may be opposite to the reverse direction.

[0336] The door arm 143 may connect the door 141 and the door motor 142 , and open or close the door 141 using power generated by the door motor 142 .

[0337] For example, the door arm 143 may include a first door arm 143a and a second door arm 143b. One end of the first door arm 143a may be coupled to the door motor 142. The first door arm 143a may be rotated by the power of the door motor 142. The other end of the first door arm 143a may be rotatably coupled to the second door arm 143b. The first door arm 143a may transmit the force transmitted from the door motor 142 to the second door arm 143b. One end of the second door arm 143b may be coupled to the first door arm 143a. The other end of the second door arm 143b may be coupled to the door 141. The second door arm 143b may open or close the dust passage hole 121a by pushing or pulling the door 141.

[0338] The door unit 140 may further include a door opening / closing detecting portion 144. The door opening / closing detecting portion 144 may be provided in the housing 110, and may detect whether the door 141 is in an open state.

[0339] For example, the door opening / closing detection portions 144 may be respectively provided at both ends in the rotation region of the door arm 143. That is, in the rotation region of the door arm 143, the first door opening / closing detection portion 144a may be provided at the end in the direction in which the door 141 opens. Furthermore, in the rotation region of the door arm 143, the second door opening / closing detection portion 144b may be provided at the end in the direction in which the door 141 closes.

[0340] Therefore, when the door arm 143 moves to a predetermined position (hereinafter, referred to as "open position DP1") where the first door opening / closing detecting portion 144a is provided, the door opening / closing detecting portion 144 can detect that the door is opened. In addition, when the door arm 143 moves to a predetermined position (hereinafter, referred to as "closed position DP2"), the door opening / closing detecting portion 144 can detect that the door is closed.

[0341] The door opening / closing detecting portion 144 may transmit a signal indicating that the door is open and transmit a signal indicating that the door is closed.

[0342] The door opening / closing detection portion 144 may include a contact sensor. For example, the door opening / closing detection portion 144 may include a micro switch.

[0343] Meanwhile, the door opening / closing detecting portion 144 may also include a non-contact sensor. For example, the door opening / closing detecting portion 144 may include an infrared (IR) sensor.

[0344] With this configuration, the door unit 140 may selectively open or close at least a portion of the coupling surface 121 , thereby allowing the outside of the first outer wall surface 112 a to communicate with the first flow path 181 and / or the dust collecting portion 170 .

[0345] When the discharge cover 222 of the first cleaner 200 is opened, the door unit 140 may be opened. In addition, when the door unit 140 is closed, the discharge cover 222 of the first cleaner 200 may also be closed.

[0346] When the dust in the dust box 220 of the first cleaner 200 is removed, the door motor 142 can rotate the door 141, thereby coupling the discharge cover 222 to the dust box body 221. Specifically, the door motor 142 can rotate the door 141 so that the door 141 rotates around the hinge part 141b, and the door 141 rotating around the hinge part 141b can push the discharge cover 222 toward the dust box body 221.

[0347] Fig.11 is a view for explaining the lower surface of the dust box of the first cleaner according to the embodiment of the present disclosure, Fig.12 is a view for explaining a relationship between a first cleaner and a cover opening unit in a cleaner station according to an embodiment of the present disclosure, and Fig.13 is a perspective view for explaining a cover opening unit of a cleaner station according to an embodiment of the present disclosure.

[0348] The following will refer to Figure 5 , Figure 6 and Figures 11 to 13 The cover opening unit 150 according to the present disclosure is described.

[0349] The cleaner station 100 according to the present disclosure may include a cover opening unit 150 . The cover opening unit 150 may be provided on the coupling portion 120 and may open the discharge cover 222 of the first cleaner 200 .

[0350] The cover opening unit 150 may include a push protrusion 151 , a cover opening motor 152 , a cover opening gear 153 , a support plate 154 , and a gear box 155 .

[0351] When the first cleaner 200 is coupled, the push protrusion 151 may move to press the coupling rod 222 c.

[0352] The push protrusion 151 may be provided on the dust box guide surface 122. Specifically, a protrusion moving hole may be formed in the dust box guide surface 122, and the push protrusion 151 may be exposed to the outside by passing through the protrusion moving hole.

[0353] When the first cleaner 200 is coupled, the push protrusion 151 may be disposed at a position where the push protrusion 151 can push the coupling rod 222c. That is, the coupling rod 222c may be disposed on the protrusion moving hole. In addition, the coupling rod 222c may be disposed in the moving area of ​​the push protrusion 151.

[0354] The push protrusion 151 may reciprocate linearly to press the coupling rod 222c. Specifically, the push protrusion 151 may be coupled to the gear box 155 so that the linear motion of the push protrusion 151 may be guided. The push protrusion 151 may be coupled to the cover opening gear 153 and move together with the cover opening gear 153 through the movement of the cover opening gear 153.

[0355] For example, the pushing protrusion 151 may include a protrusion portion 151 a , a protrusion support plate 151 b , a connection portion 151 c , a gear coupling block 151 d , and a guide frame 151 e .

[0356] The protrusion 151a may be provided to push the coupling rod 222c. The protrusion 151a may be formed in a protrusion shape similar to a hook, a right triangle or a trapezoid. The protrusion support plate 151b may be connected to the protrusion 151a and formed in the form of a flat plate for supporting the protrusion 151a.

[0357] The protrusion support plate 151b may be provided to be movable along the upper surface of the gear box 155. The connection portion 151c may connect the protrusion support plate 151b and the gear coupling block 151d. The connection portion 151c may be formed to have a narrower width than the protrusion support plate 151b and the gear coupling block 151d.

[0358] The connection portion 151c may be provided to penetrate a protruding through-hole 155b formed in the gear case 155. The gear coupling block 151d may be coupled to the cover opening gear 153. The gear coupling block 151d may be fixedly coupled to the cover opening gear 153 using a member such as a screw or a part.

[0359] The gear coupling block 151d may be accommodated in the gear box 155 and may linearly reciprocate in the gear box 155 by the movement of the cover opening gear 153. The guide frames 151e may protrude and extend from both side surfaces of the gear coupling block 151d, respectively. The guide frames 151e may protrude from the gear coupling block 151d and extend in a quadrilateral column shape.

[0360] The guide frame 151e may be disposed to penetrate a guide hole 155c formed in the gear case 155. Therefore, when the gear coupling block 151d linearly moves, the guide frame 151e may linearly reciprocate along the guide hole 155c.

[0361] The cover opening motor 152 may provide power for moving the push protrusion 151. Specifically, the cover opening motor 152 may rotate the motor shaft 152a in a forward direction or a reverse direction. In this case, the forward direction may refer to a direction in which the push protrusion 151 pushes the coupling rod 222c. In addition, the reverse direction may refer to a direction in which the push protrusion 151 that pushes the coupling rod 222c returns to an original position. The forward direction may be opposite to the reverse direction.

[0362] The cover opening motor 152 may be provided outside the gear box 155. The motor shaft 152a of the cover opening motor 152 may penetrate the motor through hole 155e of the gear box 155 and may be coupled to the cover opening gear 153. For example, the motor shaft 152a may be coupled to the opening driving gear 153a and rotate together with the opening driving gear 153a.

[0363] The cover opening gear 153 may be coupled to the cover opening motor 152 and may move the push protrusion 151 using power from the cover opening motor 152. Specifically, the cover opening gear 153 may be accommodated in a gear box 155. The cover opening gear 153 may be coupled to the cover opening motor 152 and provided with power. The cover opening gear 153 may be coupled to the push protrusion 151 to move the push protrusion 151.

[0364] The cover opening gear 153 may include an opening driving gear 153a and an opening driven gear 153b. Specifically, the shaft 152a of the cover opening motor 152 is inserted and coupled to the opening driving gear 153a so that the opening driving gear 153a can receive rotational power from the cover opening motor 152.

[0365] The opening driven gear 153b may be engaged with the opening drive gear 153a and may be coupled to the gear coupling block 151d of the push protrusion 151, thereby moving the push protrusion 151. For example, the opening driven gear 153b may be formed in the form of a rack so as to engage with the opening drive gear 153a formed in the form of a pinion. The opening driven gear 153b may include a main body 153ba coupled to the gear coupling block 151d. In addition, the opening driven gear 153b may include a gear portion 153bb formed on the lower side of the main body 153ba and configured to engage with the opening drive gear 153a. In addition, the opening driven gear 153b may include a guide shaft 153bc protruding from both side surfaces of the main body 153ba. In addition, the opening driven gear 153 b may include a gear 153 bd into which the guide shaft 153 bc is inserted and coupled, and the gear 153 bd may rollably move along a guide rail 155 d formed in the inner surface of the gear case 155 .

[0366] The support plate 154 may be provided to support one surface of the dust box 220. Specifically, the support plate 154 may extend from the coupling surface 121. The support plate 154 may protrude and extend from the coupling surface 121 toward the center of the dust passage hole 121a.

[0367] The support plate 154 may protrude and extend symmetrically from the coupling surface 121 , but the present disclosure is not limited thereto, and the support plate 154 may have various shapes capable of supporting the lower extension portion 221 a of the first cleaner 200 or the lower surface of the dust box 220 .

[0368] When the first cleaner 200 is coupled to the cleaner station 100, the lower surface of the dust box 220 may be disposed in the dust passage hole 121a, and the support plate 154 may support the lower surface of the dust box 220. The discharge cover 222 may be openably and closably disposed at the lower side of the dust box 220, and the dust box 220 may include a cylindrical dust box body 221 and an extended lower extension 221a. In this case, the support plate 154 may contact the lower extension 221a and may support the lower extension 221a.

[0369] With this configuration, in a state where the support plate 154 supports the lower extension 221a, the push protrusion 151 can push the coupling rod 222c of the discharge cover 222. Therefore, the discharge cover 222 can be opened, and the dust passage hole 121a and the inside of the dust box 220 can be communicated with each other. That is, when the discharge cover 222 is opened, the flow path portion 180 and the inside of the dust box 220 can be communicated with each other, and the cleaner station 100 and the first cleaner 200 can be connected to each other so that the fluid can flow (coupling of the flow path).

[0370] The gear box 155 may be coupled to the inner surface of the housing 110 and disposed at the lower side of the coupling portion 120 in the gravity direction, and the cover opening gear 153 may be accommodated in the gear box 155. Specifically, the box body 155a has a space capable of accommodating the cover opening gear 153, and a protrusion through hole 155b penetrated by the connecting portion 151c of the push protrusion 151 is formed in the upper surface of the box body 155a. In addition, the guide hole 155c is formed in the form of a long hole in the side surface of the box body 155a in the left / right direction so that the guide frame 151e of the push protrusion 151 penetrates the guide hole 155c.

[0371] Meanwhile, a guide rail 155d may be formed on an inner surface of a lateral side in a leftward / rightward direction of the box body 155a. The guide rail 155d may support the opening driven gear 153b and guide the movement of the opening driven gear 153b.

[0372] A motor through hole 155e may be formed in one surface of the gear case 155, and the shaft 152a of the cover opening motor 152 may penetrate the motor through hole 155e.

[0373] A cover opening detecting portion 155 f may be provided on a side surface of the gear case 155 .

[0374] The cover opening detection part 155f may include a contact sensor. For example, the cover opening detection part 155f may include a micro switch. Meanwhile, the cover opening detection part 155f may also include a non-contact sensor. For example, the cover opening detection part 155f may include an infrared (IR) sensor. Therefore, the cover opening detection part 155f may detect the position of the guide frame 151e, thereby detecting the position of the push protrusion 151.

[0375] The cover opening detection parts 155f may be respectively provided at both ends of the guide hole 155c formed in the form of a long hole. That is, in the moving area of ​​the guide frame 151e, the first cover opening detection part 155fa may be provided at the end in the direction in which the discharge cover 222 is opened. In addition, in the moving area of ​​the guide frame 151e, the second cover opening detection part 155fb may be provided at the end in the direction in which the protrusion 151 is pushed back to the original position.

[0376] Therefore, when the push protrusion 151 moves to a position where the push protrusion 151 can push the coupling rod 222c to open the discharge cover 222, the guide frame 151e can be positioned at a predetermined position (hereinafter, referred to as "cover open position CP1"), and the cover open detection portion 155f can send a signal indicating that the discharge cover 222 is opened. In addition, when the push protrusion 151 returns to the original position, the guide frame 151e can be positioned at a predetermined position (hereinafter, referred to as "cover non-open position CP2"), and the cover open detection portion 155f can send a signal indicating that the push protrusion 151 has returned to the original position.

[0377] With this configuration, the cover opening unit 150 can selectively open or close the lower portion of the dust box 220 by separating the coupling rod 222c from the dust box 220. In this case, dust in the dust box 220 can be captured in the dust collecting portion 170 by the impact that occurs when the discharge cover 222 is separated from the dust box 220.

[0378] Therefore, when the main body 210 of the first cleaner 200 is fixed to the coupling portion 120, the cover opening motor 152 can move the push protrusion 151 to separate the discharge cover 222 from the dust box 220. When the discharge cover 222 is separated from the dust box 220, the dust in the dust box 220 can be captured in the dust collecting portion 170.

[0379] Therefore, according to the present disclosure, even if the user individually opens the discharge cover 222 of the first cleaner, the cover opening unit 150 may open the dust box 220 , and thus, convenience may be improved.

[0380] Furthermore, since the discharge cover 222 is opened in a state in which the first cleaner 200 is coupled to the cleaner station 100, dust may be prevented from being scattered.

[0381] at the same time, Fig.14 2 is a view for explaining a relationship between a first cleaner and a rod pulling unit in a cleaner station according to an embodiment of the present disclosure.

[0382] The following will refer to Figure 5 , Figure 6 and Fig.14 A rod pulling unit 160 according to the present disclosure is described.

[0383] The cleaner station 100 according to the present disclosure may include a rod pulling unit 160. The rod pulling unit 160 may be disposed on the first outer wall surface 112a of the housing 110. The rod pulling unit 160 may push the dust box compression rod 223 of the first cleaner 200 to compress dust in the dust box 220.

[0384] The rod pulling unit 160 may include a rod pulling arm 161 , an arm gear 162 , a stroke driving motor 163 , a rotation driving motor 164 , and an arm motion detecting portion 165 .

[0385] The rod pulling arm 161 is accommodated in the housing 110 and can be arranged to be movable and rotatable. For example, the rod pulling arm 161 can be accommodated in an arm receiving groove formed in the first outer wall surface 112a. In this case, when an imaginary cylindrical shape is defined relative to the lower end of the arm receiving groove, the dust box compression rod 223 can be arranged in an imaginary cylindrical shape.

[0386] The rod pulling arm 161 may be configured to push the dust box compression rod 223. The rod pulling arm 161 may be formed in a shape corresponding to the arm receiving groove. For example, the rod pulling arm 161 may be formed in a shape similar to an elongated rod.

[0387] One surface of the lever pulling arm 161 may be formed to define a continuous surface together with the first outer wall surface 112 a in a state where the lever pulling arm 161 is received in the arm receiving groove. The arm gear 162 may be coupled to one side of the other surface of the lever pulling arm 161 .

[0388] The arm gear 162 can be connected to the rod traction arm 161, the stroke drive motor 163 and the rotation drive motor 164. For example, the arm gear 162 can be formed similar to a shaft. One end of the shaft of the arm gear 162 can be fixedly connected to the rod traction arm 161. The other end of the shaft of the arm gear 162 can be provided in the form of a worm gear. Therefore, the other end of the shaft of the arm gear 162 is formed in the form of a worm gear and can be engaged with the rotation drive motor 164. The shaft of the arm gear 162 can be formed in the form of a cylindrical worm. The shaft of the arm gear 162 can be formed in the form of a worm gear and can be engaged with the stroke drive motor 163.

[0389] The stroke drive motor 163 can provide power for the stroke movement of the rod traction arm 161. The stroke drive motor 163 can rotate in a forward direction or a reverse direction. In this case, the forward direction can refer to the direction in which the rod traction arm 161 is away from the housing 110 of the cleaner station 100. In addition, the reverse direction can refer to the direction in which the rod traction arm 161 is pulled toward the cleaner station 100. The forward direction may be opposite to the reverse direction.

[0390] The rotary drive motor 164 can provide power for rotating the rod traction arm 161. The rotary drive motor 164 can rotate in a forward direction or a reverse direction. In this case, the forward direction can refer to the direction in which the rod traction arm 161 rotates to a position in which the rod traction arm 161 can push the dust box compression rod 223. In addition, the reverse direction can be a direction opposite to the forward direction.

[0391] The stroke drive motor 163 and the rotation drive motor 164 may be disposed in the housing 110 .

[0392] The arm movement detection part 165 may be provided in the housing 110. The arm movement detection part 165 may be provided on the movement route of the shaft of the arm gear 162. The arm movement detection part 165 may be provided at the original position LP1, the maximum stroke movement position LP2, and the position LP3 when the dust box compression rod 223 is pulled of the shaft of the arm gear 162, respectively.

[0393] The arm motion detection part 165 may include a contact sensor. For example, the arm motion detection part 165 may include a micro switch. At the same time, the arm motion detection part 165 may also include a non-contact sensor. For example, the arm motion detection part 165 may include an infrared (IR) sensor. Through this configuration, the arm motion detection part 165 can detect the stroke position of the arm gear 162.

[0394] In addition, the arm motion detection part 165 can be arranged at the other end of the shaft of the arm gear 162. The arm motion detection part 165 can be arranged at the other end of the arm gear 162 provided in the form of a worm gear, and can detect the rotation position. The arm motion detection part 165 can include a contact sensor. For example, the arm motion detection part 165 can include a micro switch. At the same time, the arm motion detection part 165 can also include a non-contact sensor. For example, the arm motion detection part 165 can include an infrared (IR) sensor or a Hall sensor.

[0395] Therefore, the arm movement detection part 165 can detect that the rod pulling arm 161 is located at the original position LP1. In addition, the arm movement detection part 165 can detect that the rod pulling arm 161 has been moved away from the housing 110 to the maximum extent (LP2). In addition, the arm movement detection part 165 can detect that the rod pulling arm 161 rotates to pull the dust box compression rod 223. In addition, the arm movement detection part 165 can detect that the rod pulling arm 161 has pulled the dust box compression rod 223. In addition, the arm movement detection part 165 can detect that the rod pulling arm 161 rotates to the original position after pulling the dust box compression rod 223.

[0396] Therefore, when the first cleaner 200 is coupled to the coupling portion 120, the compression member (not shown) may move downward as the lever pulling arm 161 moves, thereby compressing the dust in the dust box 220. In one embodiment of the present specification, when the discharge cover 222 is separated from the dust box 220, the dust in the dust box 220 may be primarily captured in the dust separation portion 130 by gravity, and then the residual dust in the dust box 220 may be secondarily captured in the dust separation portion 130 by the compression portion 250. In addition, in a state where the discharge cover 222 is coupled to the dust box 220, the compression member (not shown) may compress the dust in the dust box 220 downward, and then the discharge cover 222 may be separated from the dust box 220, so that the dust in the dust box 220 may be captured in the dust separation portion 130.

[0397] at the same time, Fig.14a Another embodiment of a rod pulling unit according to the present disclosure is shown.

[0398] In order to avoid repeated description, the contents related to the rod pulling unit 160 according to the embodiment of the present disclosure may be used to describe other components except for the components specifically mentioned in the present embodiment.

[0399] In the present embodiment, the arm gear 2162 and the shaft 2166 can be separately arranged, and the arm gear 2162 and the shaft 2166 can be arranged parallel to each other. In addition, the shaft 2166 can be connected to be movable relative to the arm gear 2162 stroke. That is, in order to connect the shaft 2166 to the arm gear 2162, an internal thread can be formed on the inner surface of the connecting portion of the shaft 2166.

[0400] Therefore, when the arm gear 2162 is rotated by the operation of the stroke driving motor 2163, the shaft 2166 can perform a stroke movement along the thread of the arm gear 2162.

[0401] Meanwhile, the rod pulling arm 2161 may be disposed at one end of the shaft 2166 , the worm gear 2166 a may be disposed at the other end of the shaft 2166 , and the rotation driving motor 2164 may be engaged with the worm gear 2166 a .

[0402] Therefore, when the rotation drive motor 2164 operates, the shaft 2166 can rotate, and the rod pulling arm 2161 can rotate.

[0403] The arm movement detection part 2165 may be provided adjacent to the arm gear 2162 and arranged on the movement path of the shaft 2166. The arm movement detection part 2165 may be provided at the original position LP1, the maximum stroke movement position LP2, and the position LP3 when the dust box compression rod 223 is pulled of the shaft 2166, respectively.

[0404] That is, the first arm motion detection part 2165a can be set at the original position LP1 of the shaft. In addition, the second arm motion detection part 2165b can be set at the maximum stroke movement position LP2. In addition, the third arm motion detection part 2165c can be set at the position LP3 when the dust box compression rod 223 is pulled.

[0405] The arm motion detection part 2165 may include a contact sensor. For example, the arm motion detection part 2165 may include a micro switch. At the same time, the arm motion detection part 2165 may also include a non-contact sensor. For example, the arm motion detection part 2165 may include an infrared (IR) sensor. With this configuration, the arm motion detection part 2165 can detect the stroke position of the shaft 2166.

[0406] In addition, the arm motion detection portion 2165 may include a fourth arm motion detection portion 2165d disposed at the other end 2166a of the shaft. The fourth arm motion detection portion 2165d may detect the rotational position of the shaft 2166. The fourth arm motion detection portion 2165d may include a contact sensor. For example, the fourth arm motion detection portion 2165d may include a micro switch. At the same time, the fourth arm motion detection portion 2165d may also include a non-contact sensor. For example, the fourth arm motion detection portion 2165d may include an infrared (IR) sensor or a Hall sensor.

[0407] Therefore, the first arm motion detection portion 2165a can detect that the rod traction arm 2161 is located at the original position LP1. In addition, the second arm motion detection portion 2165b can detect that the rod traction arm 2161 has been maximally away from the housing 2110 (LP2). In addition, the fourth arm motion detection portion 2165d can detect that the rod traction arm 2161 rotates to pull the dust box compression rod 223. In addition, the third arm motion detection portion 2165c can detect that the rod traction arm 2161 has pulled the dust box compression rod 223. In addition, the fourth arm motion detection portion 2165d can detect that the rod traction arm 2161 rotates to the original position after pulling the dust box compression rod 223.

[0408] At the same time, the following will refer to Figure 2 and Figures 15 to 17 The dust collecting portion 170 is described.

[0409] The cleaner station 100 may include a dust collecting portion 170. The dust collecting portion 170 may be disposed in the housing 110. The dust collecting portion 170 may be disposed at a lower side of the coupling portion 120 in a gravity direction.

[0410] The dust collecting portion 170 may include a roll-shaped vinyl film (not shown). The roll-shaped vinyl film may be fixed to the housing 110 and unfolded downward by the load of dust dropped from the dust collecting box 220.

[0411] The cleaner station 100 may include a joint portion (not shown). The joint portion may be arranged in the housing 110. The joint portion may be arranged in the upper region of the dust collecting portion 170. The joint portion may cut and engage the upper region of the roll-shaped vinyl film in which dust is captured. Specifically, the joint portion may retract the roll-shaped vinyl film to the central region and engage the upper region of the roll-shaped vinyl film using a heating wire. The joint portion may include a first joint member (not shown) and a second joint member (not shown). The first joint member (not shown) may be moved in a first direction by a first joint drive portion 174, and the second joint member (not shown) may be moved in a second direction perpendicular to the first direction by a second joint drive portion 175.

[0412] By this configuration, dust captured from the first cleaner 200 or the second cleaner 300 can be collected in the roll-shaped vinyl film, and the roll-shaped vinyl film can be automatically joined. Therefore, the user does not have to separately bundle the bag in which the dust is captured, and as a result, the convenience of the user can be improved.

[0413] At the same time, the following will refer to Figure 2 and Figures 15 to 17 The flow path portion 180 is described.

[0414] The cleaner station 100 may include a flow path portion 180 . The flow path portion 180 may connect the first cleaner 200 or the second cleaner 300 to the dust collecting portion 170 .

[0415] The flow path portion 180 may include a first flow path 181 , a second flow path 182 , and a flow path switching valve 183 .

[0416] The first flow path 181 may connect the dust box 220 of the first cleaner 200 to the dust collecting part 170. The first flow path 181 may be provided at the rear side of the coupling surface 121. The first flow path 181 may refer to a space between the dust box 220 of the first cleaner 200 and the dust collecting part 170. The first flow path 181 may be a space formed at the rear side of the dust passage hole 121a. The first flow path 181 may be a flow path that bends downward from the dust passage hole 121a, and dust and air may flow through the first flow path 181. Dust in the dust box 220 of the first cleaner 200 may move to the dust collecting part 170 through the first flow path 181.

[0417] The second flow path 182 may connect the second cleaner 300 to the dust collecting portion 170 . Dust in the second cleaner 300 may move to the dust collecting portion 170 through the second flow path 182 .

[0418] The flow path switching valve 183 may be provided between the dust collecting portion 170, the first flow path 181, and the second flow path 182. The flow path switching valve 183 may selectively open or close the first flow path 181 and the second flow path 182 connected to the dust collecting portion 170. Therefore, it is possible to prevent a reduction in suction force caused when the plurality of flow paths 181 and 182 are opened.

[0419] For example, in a case where only the first cleaner 200 is coupled to the cleaner station 100 , the flow path switching valve 183 may connect the first flow path 181 to the dust collecting portion 170 and disconnect the second flow path 182 from the dust collecting portion 170 .

[0420] As another example, in a case where only the second cleaner 300 is coupled to the cleaner station 100 , the flow path switching valve 183 may disconnect the first flow path 181 from the dust collecting portion 170 and connect the second flow path 182 to the dust collecting portion 170 .

[0421] As yet another example, in a case where both the first cleaner 200 and the second cleaner 300 are coupled to the cleaner station 100, the flow path switching valve 183 may connect the first flow path 181 to the dust collecting portion 170 and disconnect the second flow path 182 from the dust collecting portion 170 to first remove dust in the dust collecting box 220 of the first cleaner 200. Thereafter, the flow path switching valve 183 may disconnect the first flow path 181 from the dust collecting portion 170 and connect the second flow path 182 to the dust collecting portion 170 to remove dust from the second cleaner 300. Therefore, the convenience of use of the user manually operating the first cleaner 200 may be improved.

[0422] At the same time, the following will refer to Figure 2 and Figures 15 to 17 The dust collection module 190 is described.

[0423] The cleaner station 100 may include a dust suction module 190. The dust suction module 190 may include a dust collection motor 191, a first filter 192, and a second filter (not shown).

[0424] The dust collecting motor 191 may be disposed below the dust collecting portion 170. The dust collecting motor 191 may generate suction in the first flow path 181 and the second flow path 182. Therefore, the dust collecting motor 191 may provide suction that can suck dust in the dust box 220 of the first cleaner 200 and dust in the second cleaner 300.

[0425] The dust collecting motor 191 may generate suction force by rotating. For example, the dust collecting motor 191 may be formed in a shape similar to a cylinder.

[0426] The first filter 192 may be disposed between the dust collecting portion 170 and the dust collecting motor 191. The first filter 192 may be a pre-filter.

[0427] The second filter (not shown) may be provided between the dust collecting motor 191 and the outer wall surface 112. The second filter (not shown) may be a HEPA filter.

[0428] Meanwhile, in the present embodiment, the imaginary balance maintaining space R1 may extend vertically from the ground and penetrate the dust collecting portion 170 and the dust suction module 190. For example, the balance maintaining space R1 may be an imaginary space extending vertically from the ground, and the dust collecting motor 191 may be accommodated at least in the balance maintaining space R1. That is, the balance maintaining space R1 may be an imaginary cylindrical space in which the dust collecting motor 191 is accommodated.

[0429] Therefore, the center of gravity of all components disposed in the balance maintaining space R1 may be concentrated on the dust suction module 190. In this case, since the dust suction module 190 is disposed close to the ground, the cleaner station 100 may stably maintain balance like a spinning aggregate toy.

[0430] Through this configuration, in the present disclosure, the cleaner station 100 may stably maintain balance in a state in which the first cleaner 200 is mounted on the cleaner station 100 .

[0431] The cleaner station 100 may include a charging portion 128. The charging portion 128 may be provided on the coupling portion 120. Specifically, the charging portion 128 may be provided on the coupling surface 121. In this case, the charging portion 128 may be positioned at a position facing a charging terminal provided on a battery 240 of the first cleaner 200. The charging portion 128 may be electrically connected to the first cleaner 200 coupled to the coupling portion 120. The charging portion 128 may supply power to the battery of the first cleaner 200 coupled to the coupling portion 120. That is, when the first cleaner 200 is physically coupled to the coupling surface 121, the charging portion 128 may be electrically coupled to the first cleaner 200.

[0432] In addition, the charging part 128 may include a lower charging part (not shown) disposed in the lower area of ​​the housing 110. The lower charging part may be electrically connected to the second cleaner 300, which is coupled to the lower area of ​​the housing 110. The second charger may supply power to a battery of the second cleaner 300 coupled to the lower area of ​​the housing 110.

[0433] The cleaner station 100 may include a side door (not shown). The side door may be provided in the housing 110. The side door may selectively expose the dust collecting portion 170 to the outside. Therefore, the user may easily remove the dust collecting portion 170 from the cleaner station 100.

[0434] at the same time, Fig.17 is a block diagram for explaining a control configuration of a cleaner station according to an embodiment of the present disclosure.

[0435] The following will refer to Fig.17 A control configuration according to the present disclosure is described.

[0436] The cleaner station 100 according to an embodiment of the present disclosure may further include a control unit 400 configured to control the coupling portion 120 , the fixing unit 130 , the door unit 140 , the cover opening unit 150 , the rod pulling unit 160 , the dust collecting portion 170 , the flow path portion 180 , and the dust suction module 190 .

[0437] The control unit 400 may be accommodated in the housing 110 .

[0438] The control unit 400 may be disposed on the upper side of the housing 110. For example, the control unit 400 may be disposed on the coupling portion 120. With this arrangement, the control unit 400, the fixing unit 130, the door unit 140, the cover opening unit 150, and the rod pulling unit 160 are disposed adjacent to each other, and as a result, the response performance may be improved.

[0439] In addition, the control unit 400 may be disposed on the lower side of the housing 110. For example, the control unit 400 may be disposed in the dust collection module 190. By this arrangement, the control unit 400 may be disposed adjacent to the relatively heavy dust collection motor 191 and adjacent to the ground, so that the control unit 400 may be stably supported. As a result, even if an external impact is applied to the control unit 400, damage to the control unit 400 may be prevented.

[0440] The control unit 400 may include a printed circuit board and elements mounted on the printed circuit board.

[0441] The control unit 400 may determine whether the first cleaner 200 is coupled to the cleaner station 100 .

[0442] When the user moves the first cleaner 200 to the coupling portion 120, the dust box 220 or the battery housing 230 of the first cleaner 200 passes through a predetermined area where the coupling sensor 125 can detect the first cleaner 200. For example, in the process of coupling the first cleaner 200 to the cleaner station 100, the battery housing 230 can contact the coupling sensor 125, and the coupling sensor 125 can detect the first cleaner 200.

[0443] When the coupling sensor 125 detects coupling of the first cleaner 200, the coupling sensor 125 may transmit a signal indicating that the first cleaner 200 is coupled to the coupling portion 120. In this case, the control unit 400 may receive the signal from the coupling sensor 125 and determine that the first cleaner 200 is physically coupled to the coupling portion 120.

[0444] In addition, when the first cleaner 200 is coupled at a precise position on the coupling portion 120, the lower surface of the dust box 220 and the lower surface of the battery housing 230 may contact the coupling surface 121, and the charging terminal of the charging portion 128 and the charging terminal of the first cleaner 200 may contact each other. In this case, power can be supplied to the battery 240 of the first cleaner 200 through the charging portion 128.

[0445] Therefore, when the charging part 128 supplies power to the battery 240 of the first cleaner 200, the control unit 400 can determine that the first cleaner 200 is electrically coupled to the coupling part 120. In addition, the control unit 400 can determine whether the charging part 128 supplies power to the battery 240 of the first cleaner 200, and check whether the first cleaner 200 is coupled at a precise position based on the determination result.

[0446] In this case, the control unit 400 may generate a pulse signal by turning on or off the supply of the charging voltage from the cleaner station 100 to the first cleaner 200. Therefore, the control unit 400 may transmit information to the first cleaner 200. For example, the control unit 400 may provide the first cleaner 200 with information indicating that the first cleaner 200 is coupled to the cleaner station 100.

[0447] When the control unit 400 determines that the first cleaner 200 is coupled to the coupling portion 120 , the control unit 400 may operate the fixing portion motor 133 to fix the first cleaner 200 .

[0448] When the fixing member 131 or the fixing part link 135 moves to the predetermined fixing point FP1, the fixing detection part 137 may send a signal indicating that the first cleaner 200 is fixed. The control unit 400 may receive the signal indicating that the first cleaner 200 is fixed from the fixing detection part 137 and determine that the first cleaner 200 is fixed. When the control unit 400 determines that the first cleaner 200 is fixed, the control unit 400 may stop the operation of the fixing part motor 133.

[0449] Meanwhile, when the operation of emptying the dust box 200 is finished, the control unit 400 may rotate the fixing portion motor 133 in a reverse direction to release the first cleaner 200 .

[0450] When the control unit 400 determines that the first cleaner 200 is fixed to the coupling portion 120 , the control unit 400 may operate the door motor 142 to open the door 141 of the cleaner station 100 .

[0451] When the door 141 or the door arm 143 reaches the predetermined opening position DP1, the door opening / closing detection portion 144 may send a signal indicating that the door 141 is open. The control unit 400 may receive the signal indicating that the door 141 is open from the door opening / closing detection portion 144 and determine that the door 141 is open. When the control unit 400 determines that the door 141 is open, the control unit 400 may stop the operation of the door motor 142.

[0452] Meanwhile, when the operation of emptying the dust box 200 is finished, the control unit 400 may rotate the door motor 142 in a reverse direction to close the door 141 .

[0453] When the control unit 400 determines that the door 141 is open, the control unit 400 may operate the cover opening motor 152 to open the discharge cover 222 of the first cleaner 200. As a result, the dust passage hole 121a may communicate with the inside of the dust box 220. Therefore, the cleaner station 100 and the first cleaner 200 may be coupled to each other to enable the fluid to flow (coupling of the flow path).

[0454] When the guide frame 151e reaches the predetermined opening position CP1, the cover opening detection portion 155f may transmit a signal indicating that the discharge cover 222 is opened. The control unit 400 may receive the signal indicating that the discharge cover 222 is opened from the cover opening detection portion 155f and determine that the discharge cover 222 is opened. When the control unit 400 determines that the discharge cover 222 is opened, the control unit 400 may stop the operation of the cover opening motor 152.

[0455] The control unit 400 may operate the stroke driving motor 163 and the rotation driving motor 164 to control the rod pulling arm 161 so that the rod pulling arm 161 may pull the dust box compression rod 223 .

[0456] When the arm movement detecting portion 165 detects that the arm gear 162 reaches the maximum stroke movement position LP2 , the arm movement detecting portion 165 may send a signal, and the control unit 400 may receive a signal from the arm movement detecting portion 165 and stop the operation of the stroke driving motor 163 .

[0457] When the arm movement detection part 165 detects that the arm gear 162 rotates to a position where the arm gear 162 can pull the dust box compression rod 223, the arm movement detection part 165 can send a signal, and the control unit 400 can receive a signal from the arm movement detection part 165 and stop the operation of the rotation drive motor 164.

[0458] In addition, the control unit 400 may operate the stroke driving motor 163 in a reverse direction to pull the rod pulling arm 161 .

[0459] In this case, when the arm movement detection part 165 detects that the arm gear 162 reaches the position LP3 when the dust box compression rod 223 is pulled, the arm movement detection part 165 can send a signal, and the control unit 400 can receive a signal from the arm movement detection part 165 and stop the operation of the stroke drive motor 163.

[0460] Meanwhile, when the operation of emptying the dust box 200 is finished, the control unit 400 may rotate the stroke driving motor 163 and the rotation driving motor 164 in the reverse direction to return the lever drawing arm 161 to the original position.

[0461] The control unit 400 may operate the first joint driving portion 174 and the second joint driving portion 175 to join the roll-shaped vinyl film (not shown).

[0462] The control unit 400 may control the flow path switching valve 183 of the flow path portion 180. For example, the control unit 400 may selectively open or close the first flow path 181 and the second flow path 182.

[0463] The control unit 400 may operate the dust collection motor 191 to suck the dust in the dust collection box 220 .

[0464] The control unit 400 may operate the display unit 500 to display the emptying status and charging status of the dust box of the first cleaner 200 or the second cleaner 300 .

[0465] The specific control process of the control unit 400 over time will be described below.

[0466] Meanwhile, the cleaner station 100 according to the present disclosure may include a display unit 500 .

[0467] The display unit 500 may be provided on the housing 110 , on a separate display device, or on a terminal such as a mobile phone.

[0468] The display unit 500 may be configured to include at least any one of a display panel capable of outputting letters and / or graphics and a speaker capable of outputting voice signals and sounds. The user may easily determine the status of the currently executed process, the remaining time, etc. based on the information output by the display unit 500.

[0469] at the same time, Fig.18 is a flow chart for illustrating a method of controlling a cleaner station according to an embodiment of the present disclosure.

[0470] The following will refer to Figures 5 to 18 A method of controlling a cleaner station according to an embodiment of the present disclosure is described.

[0471] The method of controlling a cleaner station according to the present disclosure includes a connection checking step S10, a dust box fixing step S20, a door opening step S30, a cover opening step S40, a dust box compression step S50, a dust collecting step S60, an additional dust box compression step S70, a dust collection end step S80, a door closing step S90, a compression end step S100, and a release step S110.

[0472] In the coupling checking step S10 , it may be checked whether the first cleaner 200 is coupled to the coupling portion 120 of the cleaner station 100 .

[0473] Specifically, in the connection check step S10, when the first cleaner 200 is connected, the connection sensor 125 provided on the guide protrusion 123 may contact the battery housing 230, and the connection sensor 125 may send a signal indicating that the first cleaner 200 is connected to the connection part 120. Alternatively, the connection sensor 125 of a non-contact sensor type provided on the side wall 124 may detect the presence of the dust box 220, and the connection sensor 125 may send a signal indicating that the first cleaner 200 is connected to the connection part 120. In addition, in the case where the connection sensor 125 is provided on the dust box guide surface 122, the dust box 220 may push the connection sensor 125 by the weight of the dust box 220, the connection sensor 125 may detect that the first cleaner 200 is connected, and the connection sensor 125 may send a signal indicating that the first cleaner 200 is connected to the connection part 120.

[0474] Therefore, in the coupling checking step S10 , the control unit 400 may receive a signal generated by the coupling sensor 125 and determine that the first cleaner 200 is coupled to the coupling portion 120 .

[0475] Meanwhile, in the connection checking step S10 according to the present disclosure, the control unit 400 may determine whether the first cleaner 200 is connected at a precise position based on whether the charging part 128 supplies power to the battery 240 of the first cleaner 200 .

[0476] Therefore, in the connection checking step S10 , the control unit 400 may receive a signal indicating that the first cleaner 200 is connected from the connection sensor 125 and check whether the charging part 128 supplies power to the battery 240 , thereby checking whether the first cleaner 200 is connected to the connection part 120 of the cleaner station 100 .

[0477] In the dust box fixing step S20 , when the first cleaner 200 is coupled to the cleaner station 100 , the fixing member 131 may hold and fix the dust box 200 .

[0478] Specifically, when the control unit 400 receives a signal indicating that the first cleaner is coupled from the coupling sensor 125 , the control unit 400 may operate the fixing portion motor 133 in a forward direction so that the fixing member 131 fixes the dust box 220 .

[0479] In this case, when the fixing member 131 or the fixing portion link 135 moves to the dust box fixing position FP1, the first fixing detecting portion 137a may transmit a signal indicating that the first cleaner 200 is fixed.

[0480] Therefore, the control unit 400 may receive a signal indicating that the first cleaner 200 is fixed from the first fixing detection portion 137 a and determine that the first cleaner 200 is fixed.

[0481] When the control unit 400 determines that the first cleaner 200 is fixed, the control unit 400 may stop the operation of the fixing part motor 133 .

[0482] In the door opening step S30 , when the dust box 220 is fixed, the door 141 may be opened.

[0483] Specifically, when the control unit 400 receives a signal indicating that the dust box 220 is fixed from the first fixing detecting portion 137a, the control unit 400 may operate the door motor 142 in the forward direction to open the dust passage hole 121a.

[0484] In this case, when the door arm 143 moves to the open position DP1 where the first door opening / closing detecting portion 144a is provided, the first door opening / closing detecting portion 144a may transmit a signal indicating that the door 141 is opened.

[0485] Therefore, the control unit 400 may receive a signal indicating that the door 141 is opened from the first door opening / closing detecting portion 144a and determine that the door 141 is opened.

[0486] When the control unit 400 determines that the door 141 is open, the control unit 400 may stop the operation of the door motor 142 .

[0487] In the cover opening step S40, when the door 141 is opened, the discharge cover 222 may be opened.

[0488] Specifically, when the control unit 400 receives a signal indicating that the door 141 is open from the first door opening / closing detecting portion 144a, the control unit 400 may operate the cover opening motor 152 in the forward direction to open the discharge cover 222. That is, the discharge cover 222 may be separated from the dust box body 221.

[0489] When the guide frame 151e reaches a predetermined cover open position CP1 where the first cover open detecting portion 155fa is provided, the cover open detecting portion 155f may transmit a signal indicating that the discharge cover 222 is opened.

[0490] In this case, the control unit 400 may receive a signal indicating that the discharge cover 222 is opened from the first cover opening detecting portion 155fa and determine that the discharge cover 222 is opened.

[0491] When the control unit 400 determines that the discharge cover 222 is opened, the control unit 400 may stop the operation of the cover opening motor 152 .

[0492] In the dust box compressing step S50 , when the discharge cover 222 is opened, the inside of the dust box 220 may be compressed.

[0493] The dust box compressing step S50 may include a first compression preparing step S51 , a second compression preparing step S52 , and a rod pulling step S53 .

[0494] In the first compression preparation step S51 , the rod pulling arm 161 or 2161 may be moved to a height at which the rod pulling arm 161 or 2161 may push the dust box compression rod 223 .

[0495] Specifically, when the control unit 400 receives a signal indicating that the discharge cover 222 is open from the first cover opening detection part 155fa, the control unit 400 can operate the stroke driving motor 163 or 2163 to move the rod pulling arm 161 or 2161 to a height equal to or higher than the height of the dust box compression rod 223.

[0496] When the arm motion detection portion 165 or 2165 detects that the lever traction arm 163 or 2163 moves to a height equal to or higher than the height of the dust box compression rod 223, the arm motion detection portion 165 or 2165 may send a signal indicating that the lever traction arm 163 or 2163 has moved to the target position. That is, when the arm motion detection portion 165 or 2165 detects that the arm gear 162 or the shaft 2166 reaches the maximum stroke movement position LP2, the arm motion detection portion 165 or 2165 may send a signal. The control unit 400 may receive a signal from the arm motion detection portion 165 or 2165 and stop the operation of the stroke drive motor 163 or 2163.

[0497] In the second compression preparation step S52 , the rod pulling arm 161 or 2161 may be rotated to a position where the rod pulling arm 161 or 2161 may push the dust box compression rod 223 .

[0498] Specifically, when the control unit 400 receives a signal from the arm movement detection part 165 or 2165 indicating that the rod traction arm 163 or 2163 has moved to a height equal to or higher than the height of the dust box compression rod 223, the control unit 400 can operate the rotational drive motor 164 or 2164 to move the rod traction arm 161 or 2161 to a position where the rod traction arm 161 or 2161 can push the dust box compression rod 223.

[0499] When the arm motion detection part 165 or 2165 detects that the arm gear 162 or the shaft 2166 rotates to a position where the arm gear 162 or the shaft 2166 can pull the dust box compression rod 223, the arm motion detection part 165 or 2165 can send a signal indicating that the rod pulling arm 163 or 2163 rotates to the target position. The control unit 400 can receive the signal from the arm motion detection part 165 or 2165 and stop the operation of the rotation drive motor 164 or 2164.

[0500] In the rod pulling step S53, the rod pulling arm 161 or 2161 may pull the dust box compression rod 223 at least once.

[0501] Specifically, after the second compression preparation step S52 , the control unit 400 may operate the stroke driving motor 163 or 2163 in a reverse direction to pull the rod pulling arm 161 or 2161 .

[0502] In this case, when the arm motion detecting portion 165 or 2165 detects that the arm gear 162 or the shaft 2166 reaches the position LP3 when the dust box compression rod 223 is pulled, the arm motion detecting portion 165 or 2165 may send a signal indicating that the dust box compression rod 223 is pulled. The control unit 400 may receive the signal from the arm motion detecting portion 165 or 2165 and stop the operation of the stroke driving motor 163 or 2163.

[0503] In the dust box compression step S50 , the dust in the dust box 220 is pre-compressed before the dust collecting motor 191 operates, and as a result, there is an effect of preventing residual dust from remaining in the dust box 220 and improving the dust collecting efficiency in the dust collecting motor 191 .

[0504] In the dust collecting step S60 , when the discharge cover 222 is opened and the inside of the dust box 220 is compressed, the dust collecting motor 191 may operate to collect dust from the dust box 220 .

[0505] Specifically, when the control unit 400 receives a signal indicating that the discharge cover 222 is opened from the first cover opening detecting portion 155fa and receives a signal indicating that the dust box compression rod 223 is pulled from the arm movement detecting portion 165 or 2165 , the control unit 400 may operate the dust collecting motor 191 .

[0506] In the dust collecting step S60, the dust in the dust box 220 may pass through the dust passage hole 121a and the first flow path 181 and then be collected in the dust collecting part 170. Therefore, the user can remove the dust in the dust box 220 without a separate operation, and as a result, convenience can be provided to the user.

[0507] In the additional dust box compression step S70 , the inside of the dust box 220 may be compressed during the operation of the dust collecting motor 191 .

[0508] Specifically, after the rod pulling step S53, the control unit 400 may operate the stroke driving motor 163 or 2163 in the forward direction to move the rod pulling arm 161 or 2161 to the height LP2 before pulling the dust box compression rod 223. In this case, the dust box compression rod 223 is also returned to the original position by an elastic member (not shown).

[0509] That is, when the arm gear 162 or the shaft 2166 reaches the maximum stroke movement position LP2 again, the arm motion detection part 165 or 2165 may send a signal. The control unit 400 may receive the signal from the arm motion detection part 165 or 2165 and stop the forward operation of the stroke driving motor 163 or 2163.

[0510] Thereafter, immediately after the dust collection motor 191 is operated or when a predetermined time elapses after the dust collection motor 191 is operated, the control unit 400 may operate the stroke driving motor 163 or 2163 in a reverse direction to pull the dust box compression rod 223 .

[0511] Meanwhile, the additional dust box compression step S70 may be performed at least once. In this case, the number of times the additional dust box compression step S70 is performed may be preset, or the user may input the number through an input portion (not shown). Alternatively, the control unit 400 may automatically set the number of times by detecting the amount of dust in the dust box 220 using a sensor or the like.

[0512] In the additional dust box compression step S70 , since the dust in the dust box 220 is compressed during the operation of the dust collecting motor 191 , there is an effect of removing the residual dust even during the operation of the dust collecting motor 191 .

[0513] In the dust collection ending step S80, when the dust collection motor 191 is operated for a predetermined time, the operation of the dust collection motor 191 may end.

[0514] Specifically, the control unit 400 may be embedded in a timer (not shown), and when the control unit 400 determines that a predetermined time has passed, the operation of the dust collecting motor 191 may be ended.

[0515] In this case, the operation time of the dust collecting motor 191 may be preset, or the user may input the operation time through an input part (not shown). Alternatively, the control unit 400 may automatically set the operation time by detecting the amount of dust in the dust collecting box 220 using a sensor or the like.

[0516] In the door closing step S90, the door 141 may be closed after the dust collection end step S80.

[0517] Specifically, after the control unit 400 stops the operation of the dust collecting motor 191, the control unit 400 may operate the door motor 142 in the reverse direction to close at least a portion of the dust passage hole 121a. That is, in the door closing step S90, the operation of collecting dust from the dust box 220 ends, and then the door 141 may rotate to close the dust passage hole 121a. In this case, the discharge cover 222 supported by the door 141 may be rotated and fastened to the dust box body 221 by the door 141, so that the lower side of the dust box body 221 can be closed.

[0518] In this case, when the door arm 143 moves to the closing position DP2 where the second door opening / closing detecting portion 144b is provided, the second door opening / closing detecting portion 144b may transmit a signal indicating that the door 141 is closed.

[0519] Therefore, the control unit 400 may receive a signal indicating that the door 141 is closed from the second door opening / closing detecting portion 144b and determine that the door 141 is closed.

[0520] When the control unit 400 determines that the door 141 is closed, the control unit 400 may stop the operation of the door motor 142 .

[0521] With this configuration, after finishing the operation of collecting dust from the dust box 220, the cleaner station 100 can automatically close the door 141 of the cleaner station 100 and simultaneously close the discharge cover 222 of the dust box 220 of the first cleaner 200. Therefore, the cleaner station 100 can block the flow path connection between the flow path portion 180 of the cleaner station 100 and the inner space of the dust box 220.

[0522] In the compression end step S100 , the rod pulling arm may return to the original position after the door closing step S90 .

[0523] The compression end step S100 may include a first return step S101 and a second return step S102.

[0524] In the first returning step S101 , the rod pulling arm 163 or 2163 may be rotated to an original position.

[0525] Specifically, when the control unit 400 receives a signal indicating that the door 141 is closed from the second door opening / closing detecting portion 144b, the control unit 400 may operate the rotation driving motor 164 or 2164 in the reverse direction to move the rod pulling arm 161 or 2161 to the original position.

[0526] When the arm motion detection part 165 or 2165 detects that the arm gear 162 or the shaft 2166 rotates the dust box compression rod 223 to the original position, the arm motion detection part 165 or 2165 can send a signal indicating that the rod pulling arm 163 or 2163 rotates to the target position. The control unit 400 can receive the signal from the arm motion detection part 165 or 2165 and stop the operation of the rotation drive motor 164 or 2164.

[0527] In the second returning step S102, the lever pulling arm 163 or 2163 may be moved to the original position by stroke.

[0528] Specifically, when the control unit 400 receives a signal indicating that the rod traction arm 163 or 2163 rotates to the target position, the control unit 400 can operate the travel drive motor 163 or 2163 in the reverse direction to move the rod traction arm 161 or 2161 to the original position (position LP1 where the rod traction arm 161 or 2161 is connected to the shell 110).

[0529] When the arm motion detection part 165 or 2165 detects that the lever traction arm 163 or 2163 moves to the home position, the arm motion detection part 165 or 2165 may send a signal indicating that the lever traction arm 163 or 2163 moves to the target position. That is, when the arm motion detection part 165 or 2165 detects that the arm gear 162 or the shaft 2166 reaches the home position LP1, the arm motion detection part 165 or 2165 may send a signal. The control unit 400 may receive the signal from the arm motion detection part 165 or 2165 and stop the operation of the stroke drive motor 163 or 2163.

[0530] In the releasing step S110 , when the door 141 is closed, the fixing portion motor 133 may be operated so that the fixing member 131 may release the dust box 220 .

[0531] Specifically, when the control unit 400 receives a signal indicating that the arm gear reaches the home position LP1 from the arm motion detecting portion 165 or 2165 , the control unit 400 may operate the fixing portion motor 133 in a reverse direction to release the dust box 220 .

[0532] In this case, when the fixing member 131 or the fixing portion link 135 moves to the dust box releasing position FP2, the second fixing detecting portion 137b may transmit a signal indicating that the first cleaner 200 is released.

[0533] Therefore, the control unit 400 may receive a signal indicating that the first cleaner 200 is released from the second fixing detecting portion 137 b and determine that the first cleaner 200 is released.

[0534] When the control unit 400 determines that the first cleaner 200 is released, the control unit 400 may stop the operation of the fixing part motor 133 .

[0535] With this configuration, when the dust channel hole 121a is closed by the door 141 of the cleaner station 100 and the discharge cover 222 of the dust box 220 is closed, the flow path connection between the flow path portion 180 of the cleaner station 100 and the internal space of the dust box 220 is blocked, so that the dust box 220 can be released and the user can separate the first cleaner 200 from the cleaner station 100.

[0536] at the same time, Fig.19is a flow chart for explaining a second embodiment of a method of controlling a cleaner station according to the present disclosure.

[0537] The following will refer to Figures 5 to 19 A method of controlling a cleaner station according to a second embodiment of the present disclosure is described.

[0538] The method of controlling the cleaner station according to the present embodiment includes a connection checking step S10, a dust box fixing step S20, a door opening step S30, a cover opening step S40, a dust collecting step S60, a dust box compressing step S70', a dust collecting end step S80, a door closing step S90, a compression end step S100 and a releasing step S110.

[0539] To avoid repeated description, the content related to the method of controlling a cleaner station according to the aforementioned embodiment of the present disclosure may be used to describe the connection checking step S10, the dust box fixing step S20, the door opening step S30, the cover opening step S40, the dust collection end step S80, the door closing step S90, the compression end step S100 and the release step S110 according to the second embodiment.

[0540] In this embodiment, the dust collecting step S60 may be performed after the cover opening step S40.

[0541] Specifically, in the dust collecting step S60 , when the discharge cover 222 is opened, the dust collecting motor 191 may operate to collect dust from the dust collecting box 220 .

[0542] Specifically, when the control unit 400 receives a signal indicating that the discharge cover 222 is opened from the first cover opening detection portion 155 fa , the control unit 400 may operate the dust collecting motor 191 .

[0543] In the dust collecting step S60, the dust in the dust box 220 may pass through the dust passage hole 121a and the first flow path 181 and then be collected in the dust collecting part 170. Therefore, the user can remove the dust in the dust box 220 without a separate operation, and as a result, convenience can be provided to the user.

[0544] In addition, in the dust box compressing step S70 ′ according to the present embodiment, the dust box 220 may be compressed during the operation of the dust collecting motor 191 .

[0545] The dust box compressing step S70' may include a first compression preparing step S71', a second compression preparing step S72', a rod pulling step S73', and an additional pulling step S74'.

[0546] In this case, the first compression preparation step S71 ′ and the second compression preparation step S72 ′ may be performed after the operation of the dust collecting motor 191 or performed before the operation of the dust collecting motor 191 .

[0547] In the first compression preparation step S71 ′, the rod pulling arm 161 or 2161 may be moved to a height at which the rod pulling arm 161 or 2161 can push the dust box compression rod 223 .

[0548] Specifically, the control unit 400 may operate the stroke driving motor 163 or 2163 to move the rod drawing arm 161 or 2161 to a height equal to or higher than that of the dust box compression rod 223 .

[0549] When the arm motion detection portion 165 or 2165 detects that the lever traction arm 163 or 2163 moves to a height equal to or higher than the height of the dust box compression rod 223, the arm motion detection portion 165 or 2165 may send a signal indicating that the lever traction arm 163 or 2163 has moved to the target position. That is, when the arm motion detection portion 165 or 2165 detects that the arm gear 162 or the shaft 2166 reaches the maximum stroke movement position LP2, the arm motion detection portion 165 or 2165 may send a signal. The control unit 400 may receive a signal from the arm motion detection portion 165 or 2165 and stop the operation of the stroke drive motor 163 or 2163.

[0550] In the second compression preparation step S72 ′, the rod pulling arm 161 or 2161 may be rotated to a position where the rod pulling arm 161 or 2161 may push the dust box compression rod 223 .

[0551] Specifically, when the control unit 400 receives a signal from the arm movement detection part 165 or 2165 indicating that the rod traction arm 163 or 2163 has moved to a height equal to or higher than the height of the dust box compression rod 223, the control unit 400 can operate the rotational drive motor 164 or 2164 to move the rod traction arm 161 or 2161 to a position where the rod traction arm 161 or 2161 can push the dust box compression rod 223.

[0552] When the arm motion detection part 165 or 2165 detects that the arm gear 162 or the shaft 2166 rotates to a position where the arm gear 162 or the shaft 2166 can pull the dust box compression rod 223, the arm motion detection part 165 or 2165 can send a signal indicating that the rod pulling arm 163 or 2163 rotates to the target position. The control unit 400 can receive the signal from the arm motion detection part 165 or 2165 and stop the operation of the rotation drive motor 164 or 2164.

[0553] In the rod pulling step S73 ′, the rod pulling arm 161 or 2161 may pull the dust box compression rod 223 at least once.

[0554] Specifically, after the second compression preparation step S72 ′, the control unit 400 may operate the stroke driving motor 163 or 2163 in a reverse direction to pull the rod pulling arm 161 or 2161 .

[0555] In this case, when the arm motion detecting portion 165 or 2165 detects that the arm gear 162 or the shaft 2166 reaches the position LP3 when the dust box compression rod 223 is pulled, the arm motion detecting portion 165 or 2165 may send a signal indicating that the dust box compression rod 223 is pulled. The control unit 400 may receive the signal from the arm motion detecting portion 165 or 2165 and stop the operation of the stroke driving motor 163 or 2163.

[0556] In the additional pulling step S74 ′, the rod pulling arm 161 or 2161 may additionally pull the dust box compression rod 223 .

[0557] In this case, whether to perform the additional traction step S74' and the number of times to perform the additional traction step S74' may be preset, or the user may input whether to perform the additional traction step S74' and the number of times to perform the additional traction step S74' through an input part (not shown). Alternatively, the control unit 400 may detect the amount of dust in the dust box 220 using a sensor or the like, and automatically set whether to perform the additional traction step S74' and the number of times to perform the additional traction step S74'.

[0558] After the rod pulling step S73', the control unit 400 may operate the stroke driving motor 163 or 2163 in the forward direction to move the rod pulling arm 161 or 2161 to the height LP2 before pulling the dust box compression rod 223. In this case, the dust box compression rod 223 is also returned to the original position by an elastic member (not shown).

[0559] That is, when the arm gear 162 or the shaft 2166 reaches the maximum stroke movement position LP2 again, the arm motion detection part 165 or 2165 may send a signal. The control unit 400 may receive the signal from the arm motion detection part 165 or 2165 and stop the forward operation of the stroke driving motor 163 or 2163.

[0560] Thereafter, immediately after the dust collection motor 191 is operated or when a predetermined time elapses after the dust collection motor 191 is operated, the control unit 400 may operate the stroke driving motor 163 or 2163 in a reverse direction to pull the dust box compression rod 223 .

[0561] According to the present embodiment, since the dust box compression rod 223 is pulled an appropriate number of times during the operation of the dust collection motor 191, there is an effect of reducing the time taken to empty the dust box 220.

[0562] at the same time, Fig. 20 is a flow chart for explaining a third embodiment of a method of controlling a cleaner station according to the present disclosure.

[0563] The following will refer to Figures 5 to 20 A method of controlling a cleaner station according to a third embodiment of the present disclosure is described.

[0564] The method of controlling the cleaner station according to the present embodiment includes a connection checking step S10, a dust box fixing step S20, a door opening step S30, a cover opening step S40, a dust box compressing step S50', a dust collecting step S60, a dust collecting ending step S80, a door closing step S90, a compression ending step S100 and a releasing step S110.

[0575] In this case, when the arm motion detecting portion 165 or 2165 detects that the arm gear 162 or the shaft 2166 reaches the position LP3 when the dust box compression rod 223 is pulled, the arm motion detecting portion 165 or 2165 may send a signal indicating that the dust box compression rod 223 is pulled. The control unit 400 may receive the signal from the arm motion detecting portion 165 or 2165 and stop the operation of the stroke driving motor 163 or 2163.

[0576] In the additional pulling step S54 ′, the rod pulling arm 161 or 2161 may additionally pull the dust box compression rod 223 .

[0577] In this case, whether to perform the additional traction step S54' and the number of times to perform the additional traction step S54' may be preset, or the user may input whether to perform the additional traction step S54' and the number of times to perform the additional traction step S54' through an input part (not shown). Alternatively, the control unit 400 may detect the amount of dust in the dust box 220 using a sensor or the like, and automatically set whether to perform the additional traction step S54' and the number of times to perform the additional traction step S54'.

[0578] After the rod pulling step S53', the control unit 400 may operate the stroke driving motor 163 or 2163 in the forward direction to move the rod pulling arm 161 or 2161 to the height LP2 before pulling the dust box compression rod 223. In this case, the dust box compression rod 223 is also returned to the original position by an elastic member (not shown).

[0579] That is, when the arm gear 162 or the shaft 2166 reaches the maximum stroke movement position LP2 again, the arm motion detection part 165 or 2165 may send a signal. The control unit 400 may receive the signal from the arm motion detection part 165 or 2165 and stop the forward operation of the stroke driving motor 163 or 2163.

[0580] Thereafter, immediately after the dust collection motor 191 is operated or when a predetermined time elapses after the dust collection motor 191 is operated, the control unit 400 may operate the stroke driving motor 163 or 2163 in a reverse direction to pull the dust box compression rod 223 .

[0581] In this embodiment, the dust collecting step S60 is performed after the dust box compressing step S50 ′.

[0582] Therefore, in the dust collecting step S60 , when the discharge cover 222 is opened and the inside of the dust box 220 is compressed a preset number of times, the dust collecting motor 191 may operate to collect dust from the dust box 220 .

[0583] According to the present embodiment, since the dust collection motor 191 is operated after the dust box compression rod 223 is pulled an appropriate number of times, there is an effect of reducing the time taken to empty the dust box 220 .

[0584] at the same time, Fig.21 is a flow chart for explaining a fourth embodiment of a method of controlling a cleaner station according to the present disclosure.

[0585] The following will refer to Figures 5 to 21 A method of controlling a cleaner station according to a fourth embodiment of the present disclosure is described.

[0586] The method of controlling the cleaner station according to the present embodiment includes a connection checking step S10, a dust box fixing step S20, a door opening step S30, a cover opening step S40, a dust collecting step S60, a dust collecting end step S80, a door closing step S90, a compression end step S100, and a releasing step S110.

[0587] This embodiment may be applied when a first cleaner without a dust box compression bar 223 is coupled to the cleaner station 100 or when the dust box needs to be emptied quickly.

[0588] Whether to apply this embodiment may be preset or input by the user through an input portion (not shown). Alternatively, whether to apply this embodiment may be automatically set by the control unit 400 based on whether there is a dust box compression rod 223 detected by a sensor or the like.

[0589] In the present embodiment, the step of compressing the dust box 220 is eliminated, which allows the dust box 220 to be emptied most quickly.

[0590] Although the present disclosure has been described with reference to specific embodiments, the specific embodiments are only used to specifically explain the present disclosure, and the present disclosure is not limited to the specific embodiments. Obviously, those skilled in the art can modify or change the present disclosure without departing from the technical spirit of the present disclosure.
