Description

Technical Field

[0001] This disclosure relates to a cleaner station and a method for controlling the cleaner station, and more specifically, to a cleaner station configured to draw dust stored in the cleaner into the cleaner station and a method for controlling the cleaner station. Background Technology

[0002] Generally, a cleaner refers to an appliance that uses an electric suction device to draw in small debris or dust and fills the dust collection box provided with the product with the debris or dust. Such cleaners are often called vacuum cleaners.

[0003] Cleaners can be divided into manual cleaners, which are moved directly by the user to perform cleaning operations, and automatic cleaners, which perform cleaning operations while moving autonomously. Based on their shape, manual cleaners can be further categorized into drum cleaners, upright cleaners, handheld cleaners, pole cleaners, etc.

[0004] In the past, canister cleaners were widely used as household cleaners. However, recently, there has been an increasing preference for handheld and stick cleaners that integrate a dust collection box and cleaner body for improved ease of use.

[0005] In the case of a canister cleaner, the main body and the suction port are connected by a rubber hose or tube, and in some cases, the canister cleaner can be used with the brush attached to the suction port.

[0006] Handheld cleaners (portable vacuum cleaners) offer maximum portability and are lightweight. However, due to their short length, they can limit the area they can clean. Therefore, handheld cleaners are typically used for cleaning surfaces such as tables, sofas, or vehicle interiors.

[0007] Users can use the pole cleaner while standing, allowing them to perform cleaning operations without bending their backs. Therefore, the pole cleaner is advantageous for cleaning wide areas while moving around the space. While handheld cleaners are suitable for cleaning narrow spaces, pole cleaners are suitable for cleaning wide spaces and also for high places that are inaccessible to the user's hands. Recently, modular pole cleaners have been available, actively changing the type of cleaner and enabling its use in cleaning a variety of places.

[0008] In addition, robotic cleaners that perform cleaning operations autonomously without user intervention have recently been used. As the robotic cleaner moves autonomously through the area to be cleaned, it automatically cleans the area by sucking up foreign objects such as dust from the floor.

[0009] To this end, the robot cleaner includes a distance sensor configured to detect a distance from an obstacle (e.g., furniture, office supplies, or a wall) installed in a region to be cleaned and left and right wheels for moving the robot cleaner.

[0010] In this case, the left and right wheels are configured to be rotated by left and right wheel motors, respectively, and the robot cleaner cleans a room while autonomously changing its direction by operating the left and right wheel motors.

[0011] However, since the hand-held cleaner, the stick cleaner, or the robot cleaner in the related art has a small-capacity dust collection tank for storing collected dust, the user is inconvenienced since the user needs to frequently empty the dust collection tank.

[0012] In addition, since dust is scattered in the process of emptying the dust collection tank, there is a problem that the scattered dust has a harmful effect on the health of the user.

[0013] In addition, if the residual dust is not removed from the dust collection tank, there is a problem that the suction force of the cleaner is deteriorated.

[0014] In addition, if the residual dust is not removed from the dust collection tank, there is a problem that the residual dust causes an unpleasant odor.

[0015] Patent document US 2020-0129025 A1 discloses a dust collection tank combined with a stick vacuum cleaner.

[0016] In the combination of the dust collection tank and the vacuum cleaner of this patent document, the vacuum cleaner is provided to be coupled to the dust collection tank.

[0017] However, the problem of this patent document is that the user needs to directly assemble the vacuum cleaner and the dust collection tank.

[0018] In addition, there is a problem that it is not possible to compress dust in the vacuum cleaner to remove dust remaining in the cleaner.

[0019] Meanwhile, patent document US 10595692 B2 discloses a disposal station having a debris tank of a robot cleaner.

[0020] In this patent document, a station to which the 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.

[0021] 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.

[0022] However, in this patent document, dust is sucked only in the state in which the robot cleaner is coupled to the connector of the station, but there is no component to identify whether the cleaner is coupled, the cleaner is fixed, and the suction port is opened or closed.

[0023] Further, the problem of this patent document is that it is not possible to compress dust in the cleaner to remove dust remaining in the cleaner.

[0024] Meanwhile, Patent Document KR2020-0037199A discloses a cleaner.

[0025] This patent document discloses a cleaner capable of compressing dust in a dust collection box and removing dust.

[0026] However, the problem of this patent document is that the user needs to directly push the lever to compress dust in the dust collection box. SUMMARY

[0069] Meanwhile, when the lever pulling arm moves to a position where an end portion of the lever pulling arm can push the dust collecting box compression lever, the control unit can operate the stroke driving motor in a direction in which the lever pulling arm pulls the dust collecting box compression lever.

[0070] The stroke driving motor can be operated when the lever pulling arm moves to a position where an end portion of the lever pulling arm can push the dust collecting box compression lever.

[0071] When the arm movement detection portion detects that the lever pulling arm moves to the target position when the dust collecting box compression lever is pulled, the arm movement detection portion can transmit a signal indicating that the lever pulling arm is pulled.

[0073] The control unit can operate the dust collecting motor during the operation of the dust collecting motor and operate the stroke driving motor so that the lever pulling arm pulls the dust collecting box compression lever at least once.

[0074] The stroke driving motor can be operated at least once during the operation of the dust collecting motor.

[0075] After the operation of the dust collecting motor ends, the control unit can operate the door motor in a direction in which the door is closed.

[0090] Advantageous Effects

[0091] The cleaner station and the method of controlling the cleaner station according to the present disclosure can eliminate inconvenience caused by the user having to empty the dust bin at all times.

[0092] In addition, since dust in the dust bin is sucked into the station when the dust bin is emptied, dust can be prevented from being scattered.

[0093] In addition, the dust passage hole can be opened by detecting coupling of the cleaner without separate operation of the user, and dust in the dust bin is removed according to operation of the dusting motor, and thus, convenience for the user can be provided.

[0094] Furthermore, the stick cleaner and the robot cleaner can be coupled to the cleaner station at the same time, and dust in the dust bin of the stick cleaner and dust in the dust bin of the robot cleaner can be selectively removed as needed.

[0095] Furthermore, when the cleaner is coupled to the cleaner station, coupling of the cleaner can be detected, the cleaner can be automatically fixed, the suction inlet (door) of the cleaner station can be opened, and the cover of the dust bin of the cleaner can be opened.

[0096] In addition, when the cleaner station detects coupling of the dust bin, the stick is drawn to compress the dust bin so that residual dust does not remain in the dust bin, and thus, suction power of the cleaner can be increased.

[0097] Furthermore, by preventing residual dust from remaining in the dust bin, an unpleasant odor caused by residual dust can be removed. BRIEF DESCRIPTION OF DRAWINGS

[0129] In addition, the following embodiments are provided in order to more completely explain the present disclosure to those skilled in the art, and for a clearer description, the shapes and sizes of the elements shown in the drawings can be exaggerated.

[0130] 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 view showing a configuration of a dust removal system for a cleaner according to an embodiment of the present disclosure.

[0131] Referring to Figure 1 and Figure 2 , the dust removal system 10 according to the embodiments of the present specification can include a cleaner station 100 and cleaners 200 and 300. In this case, the cleaners 200 and 300 can include a first cleaner 200 and a second cleaner 300. Meanwhile, the present embodiments can be implemented without some of the above-described components, and do not exclude additional components.

[0132] The dust removal system 10 can include the cleaner station 100. The first cleaner 200 and the second cleaner 300 can be provided on the cleaner station 100. The first cleaner 200 can be coupled to a side surface of the cleaner station 100. Specifically, a main body of the first cleaner 200 can be coupled to the side surface of the cleaner station 100. The second cleaner 300 can be coupled to a lower portion of the cleaner station 100. The cleaner station 100 can remove dust from a dust collection box 220 of the first cleaner 200. The cleaner station 100 can remove dust from a dust collection box (not shown) of the second cleaner 300.

[0133] Meanwhile, 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 4is a view for explaining a center of gravity of the first cleaner according to an embodiment of the disclosure.

[0134] First, to help understand the cleaner station 100 according to the disclosure, below will refer to Figures 1 to 4 The structure of the first cleaner 200 will be described.

[0135] The first cleaner 200 can refer to a cleaner configured to be manually operated by a user. For example, the first cleaner 200 can refer to a hand-held cleaner or a stick cleaner.

[0136] The first cleaner 200 can be installed on the cleaner station 100. The first cleaner 200 can be supported by the cleaner station 100. The first cleaner 200 can be coupled to the cleaner station 100.

[0137] The first cleaner 200 can include a main body 210. The main body 210 can include a main body case 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.

[0138] The main body case 211 can define the appearance of the first cleaner 200. The main body case 211 can provide a space in which the suction motor 214 and a filter (not shown) can be accommodated. The main body case 211 can be formed in a shape similar to a cylinder.

[0139] The suction portion 212 can protrude outward from the main body case 211. For example, the suction portion 212 can be formed in a cylindrical shape with an inner opening. The suction portion 212 can communicate with the extension tube 280. The suction portion 212 can provide a flow path (hereinafter, referred to as "suction flow path") through which air containing dust can flow.

[0140] Meanwhile, in the present embodiment, an imaginary center line passing through the center of the cylindrical suction portion 212 can be defined. That is, an imaginary suction flow path center line a2 passing through the center of the suction flow path can be defined.

[0141] In this case, the suction flow path center line a2 can 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.

[0142] The dust separation portion 213 can communicate with the suction portion 212. The dust separation portion 213 can separate dust introduced into the dust separation portion 213 through the suction portion 212. The dust separation portion 213 can communicate with the dust collection bin 220.

[0143] For example, the dust separation section 213 can be a cyclone separator section capable of separating dust using swirling flow. Furthermore, the dust separation section 213 can be connected to the suction section 212. Therefore, the air and dust introduced through the suction section 212 flow spirally along the inner circumferential surface of the dust separation section 213. Thus, a swirling flow can be generated around the central axis of the dust separation section 213.

[0144] Meanwhile, in this embodiment, the central axis of the cyclone section can be an imaginary cyclone central axis a4 extending in the vertical direction.

[0145] In this case, the cyclone's central axis a4 can be an imaginary line connecting the centers of gravity on the plane formed by cutting the dust separation section 213 along the axial and radial directions. For example, the cyclone's central axis a4 can be coaxially defined with the motor axis a1, which will be described below.

[0146] The suction motor 214 can generate suction for drawing air. The suction motor 214 can be housed in the main body housing 211. The suction motor 214 can generate suction by rotation. For example, the suction motor 214 can be formed into a shape similar to a cylinder.

[0147] Meanwhile, in this embodiment, the imaginary motor axis a1 can be formed by extending the central axis of the suction motor 214.

[0148] In this case, the motor axis a1 can be an imaginary line connecting the center of gravity on the plane formed by cutting the suction motor 214 along the axial and radial directions.

[0149] The exhaust cover 215 can be disposed on one side of the main housing 211 in the axial direction. The exhaust cover 215 can accommodate a filter for filtering air. For example, a HEPA filter can be accommodated in the exhaust cover 215.

[0150] The exhaust cover 215 may have an exhaust port 215a for discharging air introduced by the suction of the suction motor 214.

[0151] A flow guide may be provided on the exhaust cover 215. The flow guide can guide the airflow to be discharged through the exhaust port 215a.

[0152] The user can grip the handle 216. The handle 216 can be located behind the suction motor 214. For example, the handle 216 can be formed into a cylindrical shape. Alternatively, the handle 216 can be formed into a curved cylinder. The handle 216 can be positioned at a predetermined angle relative to the main housing 211, the suction motor 214, or the dust separation section 213.

[0153] Meanwhile, in this embodiment, the imaginary handle axis a3 can be formed by extending the central axis of the handle 216.

[0154] In this case, the handle axis a3 can be an imaginary line connecting the center of gravity on the plane formed by cutting the handle 216 in the axial and radial directions.

[0155] The shaft of the suction motor 214 can be located between the suction part 212 and the handle 216. That is, the motor shaft a1 can be located between the suction part 212 and the handle 216.

[0156] Furthermore, the handle axis a3 can be set at a predetermined angle relative to the motor axis a1 or the suction flow path centerline a2. Therefore, there can be an intersection point where the handle axis a3 intersects with the motor axis a1 or the suction flow path centerline a2.

[0157] Meanwhile, the motor axis a1, the suction flow path centerline a2, and the handle axis a3 can be set on the same plane S1.

[0158] With this configuration, the center of gravity of the entire first cleaner 200 according to this disclosure can be set symmetrically with respect to the plane S1.

[0159] Meanwhile, in the embodiments of this disclosure, the forward direction may refer to the direction in which the suction part 212 is set based on the suction motor 214, and the backward direction may refer to the direction in which the handle 216 is set.

[0160] 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, it can prevent the parts of the first cleaner 200 from coming into contact with the user's arm.

[0161] The extension 217 can extend from the handle 216 toward the main housing 211. At least a portion of the extension 217 can extend in the horizontal direction.

[0162] The operating part 218 can be disposed on the handle 216. The operating part 218 can be disposed on an inclined surface formed in the upper region of the handle 216. The user can input commands to operate or stop the first cleaner 200 through the operating part 218.

[0163] The first cleaner 200 may include a dust collection box 220. The dust collection box 220 may be in communication with the dust separation section 213. The dust collection box 220 may store the dust separated by the dust separation section 213.

[0164] The dust collection box 220 may include a dust collection box body 221, a discharge cover 222, a dust collection box compression rod 223, and a compression component (not shown).

[0165] The dust collection box body 221 can provide space for storing dust separated by the dust separation section 213. For example, the dust collection box body 221 can be formed into a shape similar to a cylinder.

[0166] Meanwhile, in this embodiment, the hypothetical dust collection box axis a5 can be formed by extending the central axis of the dust collection box body 221.

[0167] In this case, the dust collection box axis a5 can be an imaginary line connecting the center of gravity on the plane formed by cutting the dust collection box 220 along the axial and radial directions. For example, the dust collection box axis a5 can be defined coaxially with the motor axis a1.

[0168] Therefore, the dust collection box axis a5 can also be set on the plane S1, which includes the motor axis a1, the suction flow path centerline a2, and the handle axis a3.

[0169] A portion of the lower side of the dust collection box body 221 can be opened. Furthermore, a lower extension 221a can be formed on the lower side of the dust collection box body 221. The lower extension 221a can be formed to block a portion of the lower side of the dust collection box body 221.

[0170] The dust collection box 220 may include a discharge cover 222. The discharge cover 222 may be disposed on the lower side of the dust collection box 220. The discharge cover 222 may selectively open or close the lower side of the downward-opening dust collection box 220.

[0171] 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 collection box body 221. The cover body 222a may rotate downward about the hinge portion 222b. The hinge portion 222b may be disposed adjacent to the battery housing 230. The discharge cover 222 may be hook-fitted to the dust collection box 220.

[0172] The dust collection box may also include a connecting rod 222c. The discharge cover 222 can be separated from the dust collection box 220 via the connecting rod 222c. The connecting rod 222c may be located on the front side of the dust collection box. Specifically, the connecting rod 222c may be located on the outer surface of the front side of the dust collection box 220. When an external force is applied to the connecting rod 222c, the connecting rod 222c can elastically deform the hook extending from the cover body 222a to release the hook engagement between the cover body 222a and the dust collection box body 221.

[0173] When the discharge cover 222 is closed, the lower side of the dust collection box 220 can be blocked (sealed) by the discharge cover 222 and the lower extension 221a.

[0174] The dust collection box 220 may include a dust collection box compression rod 223. The dust collection box compression rod 223 may be disposed outside the dust collection box 220 or the dust separation section 213. The dust collection box compression rod 223 may be disposed outside the dust collection box 220 or the dust separation section 213 so that it can move upward and downward. The dust collection box compression rod 223 may be connected to a compression member (not shown). When the dust collection box compression rod 223 moves downward by an external force, the compression member (not shown) may also move downward. This provides convenience for the user. The compression member (not shown) and the dust collection box compression rod 223 may return to their original positions via an elastic member (not shown). Specifically, when the external force applied to the dust collection box compression rod 223 is removed, the elastic member may move the dust collection box compression rod 223 and the compression member (not shown) upward.

[0175] A compression member (not shown) may be disposed inside the dust collection box body 221. The compression member is movable within the internal space of the dust collection box body 221. Specifically, the compression member can move upwards and downwards within the dust collection box body 221. Therefore, the compression member can compress the dust in the dust collection box body 221 downwards. Additionally, when the discharge cover 222 is separated from the dust collection box body 221, and thus the lower side of the dust collection box 220 is opened, the compression member can move from the upper side of the dust collection box 220 to the lower side of the dust collection box 220, thereby removing foreign matter such as residual dust from the dust collection box 220. Therefore, the suction power of the cleaner can be improved by preventing residual dust from remaining in the dust collection box 220. Furthermore, by preventing residual dust from remaining in the dust collection box 220, unpleasant odors caused by residual dust can be removed.

[0176] The first cleaner 200 may include a battery housing 230. A battery 240 may be housed in the battery housing 230. The battery housing 230 may be disposed on the underside of the handle 216. For example, the battery housing 230 may have a hexahedral shape with an opening on its underside. The rear surface of the battery housing 230 may be connected to the handle 216.

[0177] The battery housing 230 may include a receiving portion with an opening on its lower side. The battery 240 can be attached to or detached through the receiving portion of the battery housing 230.

[0178] The first cleaner 200 may include a battery 240.

[0179] For example, battery 240 may be detachably connected to the first cleaner 200. Battery 240 may also be detachably connected to battery housing 230. For example, battery 240 may be inserted into battery housing 230 from the underside of battery housing 230.

[0180] Alternatively, the battery 240 can be integrally housed within the battery casing 230. In this case, the lower surface of the battery 240 is not exposed to the outside.

[0181] Battery 240 can power the suction motor 214 of the first cleaner 200. Battery 240 can be located at the lower part of handle 216. Battery 240 can be located at the rear of dust collection box 220. That is, the suction motor 214 and battery 240 can be arranged so that they do not overlap each other in the upward / downward direction and are located at different heights. Based on handle 216, the heavier suction motor 214 is located at the front of handle 216, and the heavier battery 240 is located at the lower part of handle 216, so that the total weight of the first cleaner 200 can be evenly distributed. Therefore, when the user grasps handle 216 and performs cleaning operations, stress can be prevented from being applied to the user's wrist.

[0182] When the battery 240 according to this embodiment is connected to the battery housing 230, the lower surface of the battery 240 can be exposed to the outside. Because the battery 240 can be placed on the floor when the first cleaner 200 is placed on the floor, the battery 240 can be immediately separated from the battery housing 230. Furthermore, because the lower surface of the battery 240 is exposed to the outside and therefore in direct contact with the air outside the battery 240, the cooling performance of the battery 240 can be improved.

[0183] Meanwhile, since the battery 240 is integrally fixed to the battery housing 230, the number of structures for attaching or removing the battery 240 and the battery housing 230 can be reduced, resulting in a reduction in the overall size and weight of the first cleaner 200.

[0184] The first cleaner 200 may include an extension tube 250. The extension tube 250 may communicate with the cleaning module 260. The extension tube 250 may communicate with the main body 210. The extension tube 250 may communicate with the suction portion 212 of the main body 210. The extension tube 250 may be formed in the shape of an elongated cylinder.

[0185] The main body 210 can be connected to the extension tube 250. The main body 210 can be connected to the cleaning module 260 via the extension tube 250. The main body 210 can generate suction through the suction motor 214 and provide suction to the cleaning module 260 through the extension tube 250. External dust can be introduced into the main body 210 through the cleaning module 260 and the extension tube 250.

[0186] The first cleaner 200 may include a cleaning module 260. The cleaning module 260 may be in communication with an extension tube 250. Therefore, outside air can be introduced into the body 210 of the first cleaner 200 via the cleaning module 260 and the extension tube 250 by the suction generated in the body 210 of the first cleaner 200.

[0187] Dust in the dust collection bin 220 of the first cleaner 200 can be captured by the dust collection section 170 of the cleaner station 100 through the gravity and suction of the dust collection motor 191. Therefore, dust in the dust collection bin can be removed without the need for separate user operation, thus providing convenience for the user. In addition, the inconvenience caused by the user having to constantly empty the dust collection bin can be eliminated. Furthermore, when the dust collection bin is emptied, dust can be prevented from spreading.

[0188] The first cleaner 200 can be attached to the side surface of the housing 110. Specifically, the main body 210 of the first cleaner 200 can be mounted on the connecting portion 120. More specifically, the dust collection box 220 and the battery housing 230 of the first cleaner 200 can be attached to the connecting surface 121, the outer peripheral surface of the dust collection box main body 221 can be attached to the dust collection box guide surface 122, and the suction portion 212 can be attached to the suction portion guide surface 126 of the connecting portion 120 (see...). Figure 2 ).

[0189] In this embodiment, the imaginary center of gravity plane S1 can be defined and includes at least two of the following: motor axis a1, suction flow path center line a2, handle axis a3, cyclone separator center line a4, and dust collection box axis a5. That is, the center of gravity plane S1 can be an imaginary plane formed by connecting two imaginary lines, and includes an imaginary plane formed by extending the imaginary plane.

[0190] For example, the center of gravity plane S1 may include the motor axis a1 and the suction flow path centerline 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 separator centerline a4 and the suction flow path centerline a2. Alternatively, the center of gravity plane S1 may include the cyclone separator centerline a4 and the handle axis a3. Alternatively, the center of gravity plane S1 may include the dust collection box axis a5 and the suction flow path centerline a2. Alternatively, the center of gravity plane S1 may include the dust collection box axis a5 and the handle axis a3. Alternatively, the center of gravity plane S1 may include the suction flow path centerline a2 and the handle axis a3.

[0191] Therefore, the suction section 212 can be disposed on an imaginary extended plane of the center of gravity plane S1. Alternatively, the dust separation section 213 can be disposed on an imaginary extended plane of the center of gravity plane S1. Alternatively, the suction motor 214 can be disposed on an imaginary extended plane of the center of gravity plane S1. Alternatively, the handle 216 can be disposed on an imaginary extended plane of the center of gravity plane S1. Alternatively, the dust collection box 220 can be disposed on an imaginary extended plane of the center of gravity plane S1.

[0192] With this configuration, the center of gravity of the entire first cleaner 200 can be set symmetrically with respect to the center of gravity plane S1.

[0193] The dust removal system 10 may include a second cleaner 300. The second cleaner 300 may refer to a robotic cleaner. When the second cleaner 300 autonomously moves within the area to be cleaned, it automatically cleans the area by sucking up foreign objects such as dust from the floor. The second cleaner 300 (i.e., the robotic cleaner) may include a distance sensor and left and right wheels for moving the robotic cleaner. The distance sensor is configured to detect the distance to obstacles (such as furniture, office supplies, or walls) installed in the area to be cleaned. The second cleaner 300 may be coupled to a cleaning station. Dust in the second cleaner 300 may be captured in a dust collection section 170 via a second flow path (not shown).

[0194] at the same time, Figure 15 This is a view used to illustrate the arrangement relationship between the center of gravity of the cleaner station and the first cleaner according to an embodiment of the present disclosure, and Figure 16 This shows what happens when viewed from another direction. Figure 15 A view of a schematic diagram at that time.

[0195] The following will refer to Figure 1 , Figure 2 , Figure 15 and Figure 16 The cleaner station 100 is described according to this disclosure.

[0196] A first cleaner 200 and a second cleaner 300 can be mounted on a cleaner station 100. The first cleaner 200 can be attached to a side surface of the cleaner station 100. Specifically, the body of the first cleaner 200 can be attached to a side surface of the cleaner station 100. The second cleaner 300 can be attached to the lower part of the cleaner station 100. The cleaner station 100 can remove dust from the dust collection box 220 of the first cleaner 200. The cleaner station 100 can also remove dust from the dust collection box (not shown) of the second cleaner 300.

[0197] 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.

[0198] The housing 110 may have a space capable of accommodating a dust collection section 170 and a dust collection module 190, wherein the dust collection section 170 is configured to store dust and the dust collection module 190 is configured to generate a flow force for collecting dust from the dust collection section 170.

[0199] The housing 110 may include a bottom surface 111 and an outer wall surface 112.

[0200] The bottom surface 111 can support the lower side of the vacuum module 190 in the direction of gravity. That is, the bottom surface 111 can support the lower side of the dust collection motor 191 of the vacuum module 190.

[0201] In this configuration, the bottom surface 111 can be oriented towards the ground. The bottom surface 111 can also be arranged parallel to the ground or 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 collection motor 191 and maintaining overall weight balance.

[0202] In this embodiment, the bottom surface 111 may also include a ground support (not shown) to prevent the cleaner station 100 from falling and to increase the contact area with the ground to maintain balance. For example, the ground support 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 may be arranged linearly symmetrically to maintain lateral and longitudinal balance based on the front surface on which the first cleaner 200 is mounted.

[0203] The outer wall surface 112 may refer to a surface formed in the direction of gravity 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 configured to be inclined at a predetermined angle relative to the bottom surface 111.

[0204] 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.

[0205] In this embodiment, the first outer wall surface 112a may be located on the front side of the cleaner station 100. In this case, the front side may refer to the side connected to the first cleaner 200 or the second cleaner 300. Therefore, the first outer wall surface 112a may define the appearance of the front surface of the cleaner station 100.

[0206] Meanwhile, the direction is defined as follows to understand this embodiment. In this embodiment, the direction can be defined with the first cleaner 200 installed on the cleaner station 100.

[0207] In this case, the surface including the extension line 212a of the suction portion 212 can be referred to as the front surface (see...). Figure 1In other words, with the first cleaner 200 installed on the cleaner station 100, a portion of the suction portion 212 can contact and connect to the suction portion guide surface 126, and the remaining portion of the suction portion 212 not connected to the suction portion guide surface 126 can be arranged to expose to the outside from the first outer wall surface 112a. Therefore, an imaginary extension line 212a of the suction portion 212 can be provided on the first outer wall surface 112a, and the surface including the extension line 212a of the suction portion 212 can be referred to as the front surface.

[0208] On the other hand, with the lever arm 161 connected to the housing 110, the surface of the lever arm 161 that is exposed to the outside can be referred to as the front surface.

[0209] On the other hand, when the first cleaner 200 is installed on the cleaner station 100, the outer surface of the cleaner station 100 penetrated by the body 210 of the first cleaner can be referred to as the front surface.

[0210] Furthermore, when the first cleaner 200 is installed on the cleaner station 100, the direction in which the first cleaner 200 is exposed to the outside of the cleaner station 100 can be referred to as the positive direction.

[0211] Furthermore, on the other hand, when 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 can be referred to as the forward direction. Furthermore, the direction opposite to the direction in which the suction motor 214 is arranged on the cleaner station 100 can be referred to as the rearward direction.

[0212] On the other hand, the direction in which the handle axis a3 and the motor axis a1 intersect can be referred to as the positive direction based on the cleaner station 100. Alternatively, the direction in which the handle axis a3 and the suction flow path centerline a2 intersect can be referred to as the positive direction. Alternatively, the direction in which the motor axis a1 and the suction flow path centerline a2 intersect can be referred to as the positive direction. Furthermore, based on the cleaner station 100, the direction opposite to the direction in which the intersection point is set can be referred to as the rearward direction.

[0213] Furthermore, based on the internal space of the connecting portion 120 and the housing 110, the surface facing the front surface can be referred to as the rear surface of the cleaner station 100. Therefore, the rear surface can refer to the direction in which the second outer wall surface 112b is formed.

[0214] Furthermore, based on the internal space of the housing 110, the left surface when observing the front surface can be referred to as the left surface, and the right surface when observing the front surface can be referred to as the right surface. Therefore, the left surface can refer to the direction in which the third outer wall surface 112c is formed, and the right surface can refer to the direction in which the fourth outer wall surface 112d is formed.

[0215] The first outer wall surface 112a can be formed as a flat surface, or the first outer wall surface 112a can be formed as a curved surface as a whole, or formed as a surface that partially includes a curved surface.

[0216] The first outer wall surface 112a may have an appearance corresponding to the shape of the first cleaner 200. Specifically, a connecting portion 120 may be provided on the first outer wall surface 112a. With this configuration, the first cleaner 200 can be connected to and supported by the cleaner station 100. The specific configuration of the connecting portion 120 will be described below.

[0217] Furthermore, the rod traction unit 160 may be disposed on the first outer wall surface 112a. Specifically, the rod traction arm 161 of the rod traction 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 traction arm 161 may be received. In this case, the arm receiving groove may be formed to correspond to the shape of the rod traction arm 161. Therefore, when the rod traction arm 161 is mounted in the arm receiving groove, the first outer wall surface 112a and the outer surface of the rod traction arm 161 may define a continuous external shape, and the rod traction arm 161 may be traveled to protrude from the first outer wall surface 112a by operation of the rod traction unit 160.

[0218] Meanwhile, a structure for mounting various types of cleaning modules 260 for the first cleaner 200 can be additionally provided on the first outer wall surface 112a.

[0219] Furthermore, a structure can be additionally provided on the first outer wall surface 112a for the second cleaner 300 to be attached thereto. Therefore, a structure corresponding to the shape of the second cleaner 300 can be additionally provided on the first outer wall surface 112a.

[0220] Furthermore, a cleaner base plate (not shown) to which the lower surface of the second cleaner 300 can be attached may be additionally attached to the first outer wall surface 112a. Alternatively, as another embodiment, the cleaner base plate (not shown) may be shaped to connect to the bottom surface 111.

[0221] In this embodiment, the second outer wall surface 112b can be a surface facing the first outer wall surface 112a. That is, the second outer wall surface 112b can be disposed on the rear surface of the cleaner station 100. In this case, the rear surface can be a surface facing the surface to which the first cleaner 200 or the second cleaner 300 is connected. Therefore, the second outer wall surface 112b can define the appearance of the rear surface of the cleaner station 100.

[0222] For example, the second outer wall surface 112b can be formed as a flat surface. With this configuration, the cleaner station 100 can be in close contact with the wall in the room, and the cleaner station 100 can be stably supported.

[0223] As another example, a structure for mounting various types of cleaning modules 260 for the first cleaner 200 may be additionally provided on the second outer wall surface 112b.

[0224] Furthermore, a structure to which the second cleaner 300 can be attached 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.

[0225] Furthermore, a cleaner base plate (not shown) to which the lower surface of the second cleaner 300 can be attached can be additionally attached to the second outer wall surface 112b. Alternatively, as another embodiment, the cleaner base plate (not shown) can be shaped to connect to the bottom surface 111. With this configuration, when the second cleaner 300 is attached to the cleaner base plate (not shown), the overall center of gravity of the cleaner station 100 can be lowered, allowing the cleaner station 100 to be stably supported.

[0226] In this embodiment, the third outer wall surface 112c and the fourth outer wall surface 112d can refer to the surfaces connecting the first outer wall surface 112a and the second outer wall surface 112b. In this case, the third outer wall surface 112c can be disposed on the left surface of the cleaner station 100, and the fourth outer wall surface 112d can be disposed on the right surface of the cleaner station 100. Alternatively, the third outer wall surface 112c can be disposed on the right surface of the cleaner station 100, and the fourth outer wall surface 112d can be disposed on the left surface of the cleaner station 100.

[0227] The third outer wall surface 112c or the fourth outer wall surface 112d can be formed as a flat surface, or the third outer wall surface 112c or the fourth outer wall surface 112d can be formed as a curved surface as a whole, or formed as a surface that partially includes a curved surface.

[0228] Meanwhile, the structure for mounting various types of cleaning modules 260 for the first cleaner 200 can be additionally provided on the third outer wall surface 112c or the fourth outer wall surface 112d.

[0229] Furthermore, a structure to which the second cleaner 300 can be attached may 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 may be additionally provided on the third outer wall surface 112c or the fourth outer wall surface 112d.

[0230] Furthermore, a cleaner base plate (not shown) to which the lower surface of the second cleaner 300 can be attached may be additionally provided on the third outer wall surface 112c or the fourth outer wall surface 112d. Alternatively, as another embodiment, the cleaner base plate (not shown) may be shaped to connect to the bottom surface 111.

[0231] Figure 5 This is a view used to illustrate the connection portion of the cleaner station according to an embodiment of the present disclosure, and Figure 6 This is a view used to illustrate the arrangement of the fixing unit, door unit, cover opening unit and pole traction unit in a cleaner station according to an embodiment of the present disclosure.

[0232] The following will refer to Figure 5 and Figure 6 The connection portion 120 of the cleaner station 100 according to this disclosure is described.

[0233] The cleaner station 100 may include a connection portion 120 for connecting a first cleaner 200. Specifically, the connection portion 120 may be disposed in a first outer wall surface 112a, and the body 210, dust collection box 220, and battery housing 230 of the first cleaner 200 may be connected to the connection portion 120.

[0234] The connecting portion 120 may include a connecting surface 121. The connecting surface 121 may be disposed on a side surface of the housing 110. For example, the connecting 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 interior of the cleaner station 100. That is, the connecting surface 121 may refer to a surface formed with a stepped portion relative to the first outer wall surface 112a.

[0235] The first cleaner 200 can be attached to the attachment surface 121. For example, the attachment surface 121 can contact the lower surface of the dust collection box 220 and the lower surface of the battery casing 230 of the first cleaner 200. In this case, the lower surface can refer to the surface facing the ground when the user uses the first cleaner 200 or when the first cleaner 200 is placed on the ground.

[0236] In this case, the connection between the connecting surface 121 and the dust collection box 220 of the first cleaner 200 can mean a physical connection between the first cleaner 200 and the cleaner station 100, through which they are connected and fixed to each other. This can be a prerequisite for the connection of the dust collection box 220 and the flow path section 180, through which fluid can flow.

[0237] Furthermore, the connection between the connecting surface 121 and the battery housing 230 of the first cleaner 200 can refer to the physical connection between the first cleaner 200 and the cleaner station 100 through which they are connected and fixed to each other. This can be the premise for the electrical coupling between the battery 240 and the charging section 128 through which they are electrically connected to each other.

[0238] For example, the angle of the connecting surface 121 relative to the ground can be a right angle. Therefore, when the first cleaner 200 is connected to the connecting surface 121, the space of the cleaner station 100 can be minimized.

[0239] As another example, the connecting surface 121 can be configured to be inclined at a predetermined angle relative to the ground. Therefore, when the first cleaner 200 is connected to the connecting surface 121, the cleaner station 100 can be stably supported.

[0240] The connecting surface 121 may have a dust channel hole 121a through which air from outside the housing 110 is introduced into the housing 110. The dust channel hole 121a may be formed in the form of a hole corresponding to the shape of the dust collection box 220, so that dust in the dust collection box 220 can be introduced into the dust collection section 170. The dust channel hole 121a may be formed in the shape corresponding to the discharge cover 222 of the dust collection box 220. The dust channel hole 121a may be formed to communicate with the first flow path 181, which will be described below.

[0241] The connecting portion 120 may include a dust collection box guide surface 122. The dust collection box guide surface 122 may be disposed on the first outer wall surface 112a. The dust collection box guide surface 122 may be connected to the first outer wall surface 112a. In addition, the dust collection box guide surface 122 may be connected to the connecting surface 121.

[0242] The dust collection box guide surface 122 can be formed into a shape corresponding to the outer surface of the dust collection box 220. The front outer surface of the dust collection box 220 can be connected to the dust collection box guide surface 122. Therefore, it is convenient to connect the first cleaner 200 to the connection surface 121.

[0243] The connecting portion 120 may include guide protrusions 123. Guide protrusions 123 may be disposed on the connecting surface 121. Guide protrusions 123 may project upward from the connecting surface 121. Two guide protrusions 123 may be spaced apart from each other. The distance between the two spaced-apart guide protrusions 123 may correspond to the width of the battery housing 230 of the first cleaner 200. Therefore, convenience is provided when the first cleaner 200 is connected to the connecting surface 121.

[0244] The connecting portion 120 may include a sidewall 124. The sidewall 124 may refer to a wall surface disposed on one of the two side surfaces of the connecting surface 121 and may be perpendicularly connected to the connecting surface 121. The sidewall 124 may be connected to the first outer wall surface 112a. Furthermore, the sidewall 124 may be connected to the dust collection box guide surface 122. That is, the sidewall 124 may define a surface connected to the dust collection box guide surface 122. Therefore, the first cleaner 200 can be stably accommodated.

[0245] The connection portion 120 may include a connection sensor 125. The connection sensor 125 can detect whether the first cleaner 200 is connected to the connection portion 120.

[0246] The connection sensor 125 may include a contact sensor. For example, the connection sensor 125 may include a microswitch. In this case, the connection sensor 125 may be disposed on the guide protrusion 123. Thus, when the battery housing 230 or battery 240 of the first cleaner 200 is connected between a pair of guide protrusions 123, the battery housing 230 or battery 240 contacts the connection sensor 125, such that the connection sensor 125 can detect that the first cleaner 200 is physically connected to the cleaner station 100.

[0247] Meanwhile, the connection sensor 125 may include a non-contact sensor. For example, the connection sensor 125 may include an infrared (IR) sensor. In this case, the connection sensor 125 may be disposed on the side wall 124. Therefore, when the dust collection box 220 or the body 210 of the first cleaner 200 passes the side wall 124 and then reaches the connection surface 121, the connection sensor 125 can detect the presence of the dust collection box 220 or the body 210 and detect that the first cleaner 200 is physically connected to the cleaner station 100.

[0248] Meanwhile, the connection sensor 125 can be further disposed on the dust collection box guide surface 122. In this case, the connection sensor 125 may include a contact sensor. Therefore, when the first cleaner is connected, the dust collection box 220 can push the connection sensor 125 by its own weight, and the connection sensor 125 can detect that the first cleaner 200 is connected.

[0249] The connection sensor 125 can be directed toward the dust collection box 220 or the battery housing 230 of the first cleaner 200.

[0250] The connection sensor 125 may be a device for determining whether the first cleaner 200 is connected and whether the battery 240 of the first cleaner 200 is powered.

[0251] The connecting portion 120 may include a suction portion guide surface 126. The suction portion guide surface 126 may be disposed on the first outer wall surface 112a. The suction portion guide surface 126 may be connected to the dust collection box guide surface 122. The suction portion 212 may be connected 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, it provides convenience when the body 210 of the first cleaner 200 is connected to the connecting surface 121.

[0252] The connecting portion 120 may include a fixing member entry hole 127. The fixing member entry hole 127 may be formed as an elongated hole along the sidewall 124, allowing the fixing member 131 to enter and exit the fixing member entry hole 127. For example, the fixing member entry hole 127 may be a rectangular hole formed along the sidewall 124. The fixing member 131 will now be described in detail.

[0253] With this configuration, when the user connects the first cleaner 200 to the connection portion 120 of the cleaner station 100, the main body 210 of the first cleaner 200 can be stably mounted on the connection portion 120 via the first guide portion 122, the second guide portion 123, and the third guide portion 126. Therefore, it is convenient to connect the dust collection box 220 and the battery housing 230 of the first cleaner 200 to the connection surface 121.

[0254] at the same time, Figure 7 This is an exploded perspective view illustrating the fixing unit of the cleaner station according to an embodiment of the present disclosure. Figure 8 This is a view used to illustrate the arrangement of the first cleaner and the fixed unit in the cleaner station according to an embodiment of the present disclosure, and Figure 9 This is a cross-sectional view illustrating the fixing unit of the cleaner station according to an embodiment of the present disclosure.

[0255] The following will refer to Figures 5 to 9 The fixed unit 130 is described according to this disclosure.

[0256] The cleaner station 100 according to this disclosure may include a fixing unit 130. The fixing unit 130 may be disposed on a side wall 124. Furthermore, the fixing unit 130 may be disposed on the back side of the connecting surface 121. The fixing unit 130 may securely connect a first cleaner 200 to the connecting surface 121. Specifically, the fixing unit 130 may securely connect the dust collection box 220 and the battery housing 230 of the first cleaner 200 connected to the connecting surface 121.

[0257] The fixing unit 130 may include: a fixing member 131 configured to fix the dust collection box 220 and battery housing 230 of the first cleaner 200; and a fixing part motor 133 configured to operate the fixing member 131. Furthermore, the fixing unit 130 may also 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 linkage 135 configured to convert the rotational motion of the fixing part gear 134 into the reciprocating motion of the fixing member 131. Additionally, the fixing unit 130 may also include: a fixing part housing 132 configured to house the fixing part motor 133 and the fixing part gear 134.

[0258] The fixing member 131 can be disposed on the side wall 124 of the connecting portion 120 and disposed on the side wall 124 for reciprocating movement, thereby fixing the dust collection box 220. Specifically, the fixing member 131 can be accommodated in the fixing member inlet hole 127.

[0259] The fixing members 131 can be respectively provided on both sides of the connecting portion 120. For example, a pair of fixing members 131 can be symmetrically arranged with respect to the connecting surface 121.

[0260] Specifically, the fixing member 131 may include a connecting rod 131a, a movable panel 131b, and a movable seal 131c. In this case, the connecting rod 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.

[0261] A connecting rod connector 131a is provided on one side of the movable panel 131b and connected to the fixed connecting rod 135. For example, the connecting rod connector 131a can protrude from a connecting protrusion 131bb formed by bending and extending one end of the movable panel 131b into a cylindrical or circular pin shape. Therefore, the connecting rod connector 131a can be rotatably inserted into and connected to one end of the fixed connecting rod 135.

[0262] The movable panel 131b can be connected to the linkage 131a and is configured to reciprocate from the side wall 124 toward the dust collection box 220 by operation of the fixed part motor 133. For example, the movable panel 131b can be configured to move linearly and reciprocally along the guide frame 131d.

[0263] Specifically, one side of the movable panel 131b may be configured to be accommodated in a space in the first outer wall surface 112a, and the other side of the movable panel 131b may be configured to protrude from the side wall 124.

[0264] 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. Furthermore, the connecting protrusion 131bb may be provided at one end of the panel body 131ba. Additionally, the first pressing portion 131bc may be formed at the other end of the panel body 131ba.

[0265] The connecting protrusion 131bb can be formed by bending and extending one end of the panel body 131ba toward the fixed part motor 133. The connecting rod connection 131a can protrude and extend from the end of the connecting protrusion 131bb.

[0266] The connecting protrusion 131bb may have a frame through-hole through which the guide frame 131d can penetrate. For example, the frame through-hole may be formed in a shape similar to an "I".

[0267] A first pressing portion 131bc is formed at the other end of the panel body 131ba and is shaped to correspond to the shape of the dust collection box 220 so as to seal the dust collection box 220. For example, the first pressing portion 131bc can be shaped to surround a cylinder. That is, the first pressing portion 131bc can refer to the end with a concave arc shape formed on the other side of the panel body 131ba.

[0268] The second pressing portion 131bd can be connected to the first pressing portion 131bc and formed in a shape corresponding to the shape of the battery housing 230 in order to seal the battery housing 230. For example, the second pressing portion 131bd can be formed in a shape that can press the battery housing 230. That is, the second pressing portion 131bd can refer to an end with a straight shape formed on the other side of the panel body 131ba.

[0269] A movable seal 131c can be disposed at the end of the movable panel 131b in the reciprocating direction and can seal the dust collection box 220. Specifically, the movable seal 131c can be connected to the first pressing part 131bc and can seal the space between the dust collection box 220 and the first pressing part 131bc when the first pressing part 131bc surrounds and presses the dust collection box 220. In addition, the movable seal 131c can be connected to the second pressing part 131bd and can seal the space between the battery housing 230 and the second pressing part 131bd when the second pressing part 131bd surrounds and presses the battery housing 230.

[0270] The fixing unit 130 may also include a guide frame 131d, which is 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 with a through-connection protrusion 131bb. With this configuration, the movable panel 131b can reciprocate linearly along the guide frame 131d.

[0271] The fixing housing 132 may be disposed within the housing 110. For example, the fixing housing 132 may be disposed on the back side of the connecting surface 121.

[0272] The fixed portion housing 132 may have space to accommodate the fixed portion gear 134. In addition, the fixed portion housing 132 may accommodate the fixed portion motor 133.

[0273] The fixed portion housing 132 may include a first fixed portion housing 132a, a second fixed portion housing 132b, a connecting rod guide hole 132c, and a motor receiving portion 132d.

[0274] The first fixed portion housing 132a and the second fixed portion housing 132b are connected to each other to define a space in which the fixed portion gear 134 can be accommodated.

[0275] For example, the first fixing housing 132a may be disposed in the direction toward the outside of the cleaner station 100, and the second fixing housing 132b may be disposed in the direction toward the inside of the cleaner station 100. That is, the first fixing housing 132a may be disposed in the direction toward the connecting surface 121, and the second fixing housing 132b may be disposed in the direction toward the second outer wall surface 112b.

[0276] A connecting rod guide hole 132c may be formed in the first fixed part housing 132a. The connecting rod guide hole 132c may refer to a hole formed to guide the movement path of the fixed part connecting rod 135. For example, the connecting rod guide hole 132c may refer to an arc-shaped hole formed in the circumferential direction around the rotation axis of the fixed part gear 134.

[0277] Two link guide holes 132c can be formed to guide the pair of fixed link rods 135 for moving the pair of fixed members 131. Alternatively, the two link guide holes 132c can be formed symmetrically.

[0278] The motor receiving portion 132d can be configured to receive the fixed portion motor 133. For example, the motor receiving portion 132d can protrude into a cylindrical shape from the first fixed portion housing 132a to receive the fixed portion motor 133 therein.

[0279] The stationary motor 133 provides power for moving the stationary member 131. Specifically, the stationary motor 133 can rotate the stationary gear 134 in a forward or reverse direction. In this case, the forward direction can refer to the direction in which the stationary member 131 moves from the side wall 124 to press against the dust collection box 220. Conversely, the reverse direction can refer to the direction in which the stationary member 131 moves from the position where it presses against the dust collection box 220 to the inside of the side wall 124. The forward direction can be opposite to the reverse direction.

[0280] The fixed part gear 134 can be connected to the fixed part motor 133 and can use the power from the fixed part motor 133 to move the fixed member 131.

[0281] The fixed gear 134 may include a drive gear 134a, a connecting gear 134b, a first connecting rod rotating gear 134c, and a second connecting rod rotating gear 134d.

[0282] The shaft of the fixed portion motor 133 can be inserted into and connected to the drive gear 134a. For example, the shaft of the fixed portion motor 133 can be inserted into and fixedly connected to the drive gear 134a. As another example, the drive gear 134a can be integrally formed with the shaft of the fixed portion motor 133.

[0283] The connecting gear 134b can engage with the drive gear 134a and the first connecting rod rotating gear 134c.

[0284] The other end of the fixed part connecting rod 135 is rotatably connected to the first connecting rod rotating gear 134c, and the first connecting rod rotating gear 134c can transmit the rotational force transmitted from the drive gear 134a to the fixed part connecting rod 135.

[0285] The first connecting rod rotary gear 134c may include a rotating shaft 134ca, a rotating surface 134cb, gear teeth 134cc, and a connecting rod fastening part 134cd.

[0286] A rotating shaft 134ca can be connected to and supported by a first fixed housing 132a and a second fixed housing 132b. A rotating surface 134cb can be formed as a circular plate with 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 engage with a connecting gear 134b. Furthermore, gear teeth 134cc can engage with a second connecting rod rotating gear 134d. With this configuration, the first connecting rod rotating gear 134c can receive power from the fixed motor 133 via the drive gear 134a and the connecting gear 134b, and transmit the power to the second connecting rod rotating gear 134d.

[0287] The connecting rod fastening portion 134cd can protrude and extend axially from the rotating surface 134cb in a cylindrical or circular pin shape. The connecting rod fastening portion 134cd can be rotatably connected to the other end of the fixed portion connecting rod 135. For example, the connecting rod fastening portion 134cd can penetrate the connecting rod guide hole 132c and can be connected to the other end of the fixed portion connecting rod 135. With this configuration, the first connecting rod rotating gear 134c can be rotated by power from the fixed portion motor 133, and the fixed portion connecting rod 135 can be rotated and linearly moved by the rotation of the first connecting rod rotating gear 134c. Therefore, the fixing member 131 can be moved to fix or release the dust collection box 220.

[0288] The second connecting rod rotary gear 134d can engage with the first connecting rod rotary gear 134c and rotate in the opposite direction to the rotation direction of the first connecting rod rotary gear 134c.

[0289] The other end of the fixed part connecting rod 135 is rotatably connected to the second connecting rod rotating gear 134d, and the second connecting rod rotating gear 134d can transmit the rotational force transmitted from the drive gear 134a to the fixed part connecting rod 135.

[0290] The second connecting rod rotary gear 134d may include a rotating shaft 134da, a rotating surface 134db, gear teeth 134dc, and a connecting rod fastening part 134dd.

[0291] The rotating shaft 134da can be connected to and supported by the first fixed housing 132a and the second fixed housing 132b. The rotating surface 134db can be formed as a circular plate with a predetermined thickness around the rotating shaft 134da. Gear teeth 134dc can be formed on the outer peripheral surface of the rotating surface 134db and can engage with the first connecting rod rotating gear 134c. With this configuration, the second connecting rod rotating gear 134d receives power from the fixed motor 133 through the drive gear 134a, the connecting gear 134b, and the first connecting rod rotating gear 134c.

[0292] The connecting rod fastener 134dd can protrude and extend axially from the rotating surface 134db in a cylindrical or circular pin shape. The connecting rod fastener 134dd can be rotatably connected to the other end of the fixed part connecting rod 135. For example, the connecting rod fastener 134dd can penetrate the connecting rod guide hole 132c and can be connected to the other end of the fixed part connecting rod 135. With this configuration, the second connecting rod rotating gear 134d can be rotated by power from the fixed part motor 133, and the fixed part connecting rod 135 can be rotated and linearly moved by the rotation of the second connecting rod rotating gear 134d. Therefore, the fixing member 131 can be moved to fix or release the dust collection box 220.

[0293] The fixed part connecting rod 135 can connect the fixed part gear 134 and the fixed component 131, and convert the rotation of the fixed part gear 134 into the reciprocating motion of the fixed component 131.

[0294] One end of the fixed part connecting rod 135 can be connected to the connecting rod connecting part 131a of the fixed member 131, and the other end of the fixed part connecting rod 135 can be connected to the connecting rod fastening part 134cd or 134dd of the fixed part gear 134.

[0295] The fixed part of the connecting rod 135 may include a connecting rod body 135a, a first connecting rod connecting part 135b, and a second connecting rod connecting part 135c.

[0296] For example, the connecting rod body 135a can be formed as a frame with a curved center. This is to improve the efficiency of power transmission by changing the angle of force transmission.

[0297] A first connecting rod connecting portion 135b may be disposed at one end of the connecting rod body 135a, and a second connecting rod connecting portion 135c may be disposed at the other end of the connecting rod body 135a. The first connecting rod connecting portion 135b may protrude cylindrically from one end of the connecting rod body 135a. The first connecting rod connecting portion 135b may have a hole in which a connecting rod connecting portion 131a can be inserted and connected. The second connecting rod connecting portion 135c may protrude cylindrically from the other end of the connecting rod body 135a. In this case, the protruding height of the second connecting rod connecting portion 135c may be greater than the protruding height of the first connecting rod connecting portion 135b. This allows the connecting rod fastening portions 134cd and 134dd of the fixed gear 134 to be accommodated in and move along the connecting rod guide hole 132c, and to support the connecting rod fastening portions 134cd and 134dd when they rotate. The second link connecting part 135c may have a hole in which the link fastener 134cd or 134dd can be inserted and connected.

[0298] A stationary seal 136 may be disposed on the dust collection box guide surface 122 to seal the dust collection box 220 when the first cleaner 200 is connected. With this configuration, when the dust collection box 220 of the first cleaner 200 is connected, the first cleaner 200 can press the stationary seal 136 with its own weight, so that the dust collection box 220 and the dust collection box guide surface 122 can be sealed.

[0299] The stationary seal 136 can be positioned on the imaginary extension line of the movable seal 131c. With this configuration, when the stationary motor 133 operates and the stationary member 131 presses against the dust collection box 220, the periphery of the dust collection box 220 at the same height can be sealed. In other words, the stationary seal 136 and the movable seal 131c can seal the outer peripheral surface of the dust collection box 220, which is arranged concentrically.

[0300] According to this embodiment, the stationary seal 136 may be disposed on the dust collection box guide surface 122 and formed in the form of a curved line corresponding to the arrangement of the cover opening unit 150, which will be described below.

[0301] Therefore, when the main body 210 of the first cleaner 200 is mounted on the connecting portion 120, the fixing unit 130 can fix the main body 210 of the first cleaner 200. Specifically, when the connection sensor 125 detects that the main body 210 of the first cleaner 200 is connected to the connecting portion 120 of the cleaner station 100, the fixing portion motor 133 can move the fixing member 131 to fix the main body 210 of the first cleaner 200.

[0302] The fixing unit 130 may also include a fixing detection part 137 capable of detecting the movement of the fixing member 131.

[0303] The fixed detection section 137 can be installed in the housing 110 and can detect whether the dust collection box 220 is fixed.

[0304] For example, the fixing detection portions 137 can be respectively provided at both ends of the rotation area of ​​the fixing member link 135. That is, in the rotation area of ​​the fixing member link 135, the first fixing detection portion 137a can be provided at the end of the fixing member 131 in the direction of being pushed towards the dust collection box 220. In addition, in the rotation area of ​​the fixing member link 135, the second fixing detection portion 137b can be provided at the end of the fixing member 131 in the direction away from the dust collection box 220. As another example, the fixing detection portions 137 can be respectively provided at both ends of the linear motion area of ​​the fixing member 131.

[0305] Therefore, when the fixing link 135 moves to the predetermined position where the first fixing detection part 137a is provided (hereinafter also referred to as "dust box fixing position FP1"), 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. Additionally, when the fixing link 135 moves to the predetermined position where the second fixing detection part 137b is provided (hereinafter also referred to as "dust box release position FP2"), 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.

[0306] The fixed detection section 137 may include a contact sensor. For example, the fixed detection section 137 may include a microswitch.

[0307] Additionally, the fixed detection section 137 may include a non-contact sensor. For example, the fixed detection section 137 may include an infrared (IR) sensor.

[0308] The method of controlling the fixed unit 130 will now be described together with the description of the control unit 400 of the cleaner station 100 according to this disclosure.

[0309] at the same time, Figure 9a Another embodiment of the fixing unit 1130 of the cleaner station according to the present disclosure is shown.

[0310] To avoid repetitive description, the content related to the fixing unit 130 according to the embodiments of this disclosure can be used to describe other components besides those specifically mentioned in this embodiment.

[0311] In this embodiment, the fixing member 1131 can fix the dust collection box 220 and the battery housing 230 by the upward / downward linear movement of the fixing part frame 1135.

[0312] In other words, when the fixed part frame 1135 moves linearly upward by the operation of the fixed part motor 1133, the fixed member 1131 moves toward the dust collection box 220 in the side wall 124 by being guided by the fixed part frame 1135.

[0313] In this configuration, the fixed detection portions 1137 can be respectively disposed at both ends of the moving area of ​​the fixed portion frame 1135. That is, the first fixed detection portion 1137a can be disposed at the upper end of the moving area of ​​the fixed portion frame 1135. In addition, the second fixed detection portion 1137b can be disposed at the lower end of the moving area of ​​the fixed portion frame 1135.

[0314] Therefore, when the fixing frame 1135 moves to the predetermined position where the first fixing detection part 1137a is provided (hereinafter also referred to as "dust box fixing position FP1"), the sensor contact rod 1135a protruding from the fixing 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. Additionally, when the fixing frame 1135 moves to the predetermined position where the second fixing detection part 1137b is provided (hereinafter also referred to as "dust box release position FP2"), the sensor contact rod 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.

[0315] Therefore, the increased amount of vibration and impact when the discharge cover 222 of the fixed first cleaner 200 body 210 separates from the dust collection box 220 results in improved efficiency in moving dust stored in the dust collection box 220 to the dust collection section 170 of the cleaner station 100. In other words, the cleaner's suction power can be improved by preventing residual dust from remaining in the dust collection box. Furthermore, by preventing residual dust from remaining in the dust collection box, unpleasant odors caused by residual dust can be removed.

[0316] at the same time, Figure 10 This is a view used to illustrate the relationship between the first cleaner and the door units in the cleaner station according to an embodiment of the present disclosure.

[0317] The following will refer to Figure 5 , Figure 6 and Figure 10 The gate unit 140 is described according to this disclosure.

[0318] The cleaner station 100 according to this disclosure may include a door unit 140. The door unit 140 may be configured to open or close the dust passage opening 121a.

[0319] The door unit 140 may include a door 141, a door motor 142, and a door arm 143.

[0320] Door 141 can be hinged to the connecting surface 121 and can open or close the dust passage hole 121a. Door 141 may include a door body 141a, a hinge portion 141b, and an arm connecting portion 141c.

[0321] The door body 141a can be shaped to block the dust channel hole 121a. For example, the door body 141a can be shaped like a circular plate. Based on the state of the door body 141a blocking the dust channel hole 121a, the hinge portion 141b can be provided on the upper side of the door body 141a, and the arm connecting portion 141c can be provided on the lower side of the door body 141a.

[0322] The door body 141a can be shaped to seal the dust channel 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 channel hole 121a, and the inner surface of the door body 141a disposed in the cleaner station 100 is formed to have a diameter larger than the diameter of the dust channel hole 121a. Furthermore, a horizontal difference can be defined between the outer and inner surfaces. Simultaneously, one or more reinforcing ribs can protrude from the inner surface to connect the hinge portion 141b and the arm connecting portion 141c, and to reinforce the support of the door body 141a.

[0323] The hinge portion 141b can be a device that connects the door 141 to the connecting surface 121 via its hinge. The hinge portion 141b can be located at the upper end of the door body 141a and connected to the connecting surface 121.

[0324] The arm connecting portion 141c can be a device to which the door arm 143 can be rotatably connected. The arm connecting portion 141c can be disposed on the lower side of the inner surface, and the door arm 143 can be rotatably connected to the arm connecting portion 141c.

[0325] With this configuration, when the door arm 143 pulls the door body 141a with the dust passage hole 121a closed by the door 141, the door body 141a rotates about the hinge portion 141b toward the inside of the cleaner station 100, allowing the dust passage hole 121a to open. Simultaneously, when the door arm 143 pushes the door body 141a with the dust passage hole 121a open, the door body 141a rotates about the hinge portion 141b toward the outside of the cleaner station 100, allowing the dust passage hole 121a to close.

[0326] The door motor 142 provides power for rotating the door 141. Specifically, the door motor 142 can rotate the door arm 143 in a forward or reverse direction. In this case, the forward direction can 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 can be opened. Conversely, the reverse direction can 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 can be closed. The forward direction can be the opposite of the reverse direction.

[0327] The door arm 143 can connect the door 141 and the door motor 142, and use the power generated by the door motor 142 to open or close the door 141.

[0328] For example, 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 connected to a door motor 142. The first door arm 143a can rotate under the power of the door motor 142. The other end of the first door arm 143a may be rotatably connected to the second door arm 143b. The first door arm 143a can 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 connected to the first door arm 143a. The other end of the second door arm 143b may be connected to the door 141. The second door arm 143b can open or close the dust passage hole 121a by pushing or pulling the door 141.

[0329] The door unit 140 may also include a door opening / closing detection section 144. The door opening / closing detection section 144 may be disposed in the housing 110 and may detect whether the door 141 is in the open state.

[0330] For example, the door opening / closing detection portion 144 can be respectively provided at both ends of the rotation area of ​​the door arm 143. That is, in the rotation area of ​​the door arm 143, the first door opening / closing detection portion 144a can be provided at the end in the opening direction of the door 141. Furthermore, in the rotation area of ​​the door arm 143, the second door opening / closing detection portion 144b can be provided at the end in the closing direction of the door 141.

[0331] Therefore, when the door arm 143 moves to a predetermined position (hereinafter referred to as "open position DP1") where the first door opening / closing detection unit 144a is provided, the door opening / closing detection unit 144 can detect that the door is open. In addition, when the door arm 143 moves to a predetermined position (hereinafter referred to as "closed position DP2"), the door opening / closing detection unit 144 can detect that the door is closed.

[0332] The door opening / closing detection unit 144 can send a signal indicating that the door is open and a signal indicating that the door is closed.

[0333] The door opening / closing detection section 144 may include a contact sensor. For example, the door opening / closing detection section 144 may include a microswitch.

[0334] Additionally, the door opening / closing detection section 144 may also include a non-contact sensor. For example, the door opening / closing detection section 144 may include an infrared (IR) sensor.

[0335] With this configuration, the door unit 140 can selectively open or close at least a portion of the connecting surface 121, thereby allowing the outer side of the first outer wall surface 112a to communicate with the first flow path 181 and / or the dust collection section 170.

[0336] When the discharge cover 222 of the first cleaner 200 is opened, the door unit 140 can be opened. Furthermore, when the door unit 140 is closed, the discharge cover 222 of the first cleaner 200 can also be closed.

[0337] When dust is removed from the dust collection box 220 of the first cleaner 200, the door motor 142 can rotate the door 141, thereby connecting the discharge cover 222 to the dust collection box body 221. Specifically, the door motor 142 can rotate the door 141 so that the door 141 rotates about the hinge portion 141b, and the door 141 rotating about the hinge portion 141b can push the discharge cover 222 toward the dust collection box body 221.

[0338] Figure 11 This is a view illustrating the lower surface of the dust collection box of the first cleaner according to an embodiment of the present disclosure. Figure 12 This is a view used to illustrate the relationship between the first cleaner and the cover opening unit in the cleaner station according to an embodiment of the present disclosure, and Figure 13 This is a perspective view illustrating the cover opening unit of the cleaner station according to an embodiment of the present disclosure.

[0339] The following will refer to Figure 5 , Figure 6 and Figures 11 to 13 The cover opening unit 150 is described according to this disclosure.

[0340] The cleaner station 100 according to this disclosure may include a cover opening unit 150. The cover opening unit 150 may be disposed on the connecting portion 120 and may open the discharge cover 222 of the first cleaner 200.

[0341] 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 gearbox 155.

[0342] When the first cleaner 200 is connected, the push protrusion 151 is movable to press the connecting rod 222c.

[0343] A push protrusion 151 may be provided on the dust collection box guide surface 122. Specifically, a protrusion movement hole may be formed in the dust collection box guide surface 122, and the push protrusion 151 may be exposed to the outside by passing through the protrusion movement hole.

[0344] When the first cleaner 200 is connected, the push protrusion 151 can be positioned at a location where the push protrusion 151 can push the connecting rod 222c. That is, the connecting rod 222c can be provided on the protrusion's moving hole. Furthermore, the connecting rod 222c can be provided in the moving area of ​​the push protrusion 151.

[0345] The push protrusion 151 can reciprocate linearly to press the connecting rod 222c. Specifically, the push protrusion 151 can be coupled to the gearbox 155 so that the linear movement of the push protrusion 151 can be guided. The push protrusion 151 can 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.

[0346] For example, the push protrusion 151 may include a protrusion 151a, a protrusion support plate 151b, a connecting part 151c, a gear connecting block 151d, and a guide frame 151e.

[0347] The protrusion 151a can be configured to push the connecting rod 222c. The protrusion 151a can be formed into a protrusion shape similar to a hook, a right triangle, or a trapezoid. The protrusion support plate 151b can be connected to the protrusion 151a and is formed into a flat plate for supporting the protrusion 151a.

[0348] The protruding support plate 151b can be configured to move along the upper surface of the gearbox 155. The connecting portion 151c can connect the protruding support plate 151b and the gear connecting block 151d. The connecting portion 151c can be formed to have a width narrower than that of the protruding support plate 151b and the gear connecting block 151d.

[0349] The connecting part 151c may be configured to penetrate the protruding through hole 155b formed in the gearbox 155. The gear connecting block 151d may be connected to the cover opening gear 153. The gear connecting block 151d may be fixedly connected to the cover opening gear 153 using a component such as a screw or a part.

[0350] The gear connecting block 151d can be housed in the gearbox 155, and the movement of the gear 153 can be linearly reciprocated within the gearbox 155 by opening the cover. The guide frame 151e can protrude and extend from two side surfaces of the gear connecting block 151d respectively. The guide frame 151e can protrude from the gear connecting block 151d and extend in a quadrilateral prism shape.

[0351] The guide frame 151e can be configured to penetrate the guide hole 155c formed in the gearbox 155. Therefore, when the gear connecting block 151d moves linearly, the guide frame 151e can reciprocate linearly along the guide hole 155c.

[0352] The cover-opening motor 152 provides power for moving the push protrusion 151. Specifically, the cover-opening motor 152 can rotate the motor shaft 152a in a forward or reverse direction. In this case, the forward direction can refer to the direction in which the push protrusion 151 pushes the connecting rod 222c. Conversely, the reverse direction can refer to the direction in which the push protrusion 151, pushing the connecting rod 222c, returns to its original position. The forward direction can be opposite to the reverse direction.

[0353] The cover-opening motor 152 can be located outside the gearbox 155. The motor shaft 152a of the cover-opening motor 152 can penetrate the motor through-hole 155e of the gearbox 155 and can be connected to the cover-opening gear 153. For example, the motor shaft 152a can be connected to the opening drive gear 153a and rotate together with the opening drive gear 153a.

[0354] The cover-opening gear 153 can be coupled to the cover-opening motor 152, and the push protrusion 151 can be moved using the power from the cover-opening motor 152. Specifically, the cover-opening gear 153 can be housed in a gearbox 155. The cover-opening gear 153 can be coupled to the cover-opening motor 152 and powered. The cover-opening gear 153 can be coupled to the push protrusion 151 to move the push protrusion 151.

[0355] The cover opening gear 153 may include an opening drive gear 153a and an opening driven gear 153b. Specifically, the shaft 152a of the cover opening motor 152 is inserted into and connected to the opening drive gear 153a, such that the opening drive gear 153a can receive rotational power from the cover opening motor 152.

[0356] The driven gear 153b can engage with the drive gear 153a and can be connected to the gear connecting block 151d of the push protrusion 151, thereby moving the push protrusion 151. For example, the driven gear 153b can be formed in the form of a rack so as to engage with the drive gear 153a, which is formed in the form of a pinion. The driven gear 153b may include a main body portion 153ba connected to the gear connecting block 151d. In addition, the driven gear 153b may include a gear portion 153bb formed on the lower side of the main body portion 153ba and configured to engage with the drive gear 153a. Furthermore, the driven gear 153b may include guide shafts 153bc protruding from two side surfaces of the main body portion 153ba. Additionally, opening the driven gear 153b may include a gear 153bd, with a guide shaft 153bc inserted into and connected to the gear 153bd, and the gear 153bd being able to roll along a guide rail 155d formed in the inner surface of the gearbox 155.

[0357] The support plate 154 may be configured to support one surface of the dust collection box 220. Specifically, the support plate 154 may extend from the connecting surface 121. The support plate 154 may protrude and extend from the connecting surface 121 toward the center of the dust channel hole 121a.

[0358] The support plate 154 may protrude and extend symmetrically from the connecting surface 121, but this disclosure is not limited thereto, and the support plate 154 may have various shapes capable of supporting the lower extension 221a of the first cleaner 200 or the lower surface of the dust collection box 220.

[0359] When the first cleaner 200 is connected to the cleaner station 100, the lower surface of the dust collection box 220 can be disposed in the dust channel hole 121a, and the support plate 154 can support the lower surface of the dust collection box 220. The discharge cover 222 is disposed on the lower side of the dust collection box 220 and can be opened and closed, and the dust collection box 220 may include a cylindrical dust collection box body 221 and an extended lower extension 221a. In this case, the support plate 154 can contact the lower extension 221a and support the lower extension 221a.

[0360] With this configuration, and with the extension 221a supported by the support plate 154, the push protrusion 151 can push the connecting rod 222c of the discharge cover 222. Therefore, the discharge cover 222 can be opened, and the dust channel hole 121a and the interior of the dust collection box 220 can communicate with each other. That is, when the discharge cover 222 is open, the flow path portion 180 and the interior of the dust collection box 220 can communicate with each other, and the cleaner station 100 and the first cleaner 200 can be connected to each other to allow fluid flow (flow path connection).

[0361] The gearbox 155 can be connected to the inner surface of the housing 110 and is disposed below the connecting portion 120 along the direction of gravity, and the cover-opening gear 153 can be accommodated in the gearbox 155. Specifically, the housing body 155a has a space capable of accommodating the cover-opening gear 153, and a protruding through hole 155b through which the connecting portion 151c of the push protrusion 151 penetrates is formed in the upper surface of the housing body 155a. Furthermore, the guide hole 155c is formed in the form of an elongated hole in the side surface of the housing body 155a in the left / right direction, such that the guide frame 151e of the push protrusion 151 penetrates the guide hole 155c.

[0362] Meanwhile, guide rail 155d can be formed on the inner surface of the left / right lateral side of the housing body 155a. Guide rail 155d can support and guide the movement of the opening driven gear 153b.

[0363] The motor through-hole 155e can be formed in a surface of the gearbox 155, and the shaft 152a of the motor 152 can penetrate the motor through-hole 155e when the cover is opened.

[0364] The cover-opening detection section 155f can be set on the side surface of the gearbox 155.

[0365] The cover opening detection portion 155f may include a contact sensor. For example, the cover opening detection portion 155f may include a microswitch. Simultaneously, the cover opening detection portion 155f may also include a non-contact sensor. For example, the cover opening detection portion 155f may include an infrared (IR) sensor. Therefore, the cover opening detection portion 155f can detect the position of the guide frame 151e, thereby detecting the position of the push protrusion 151.

[0366] The cover opening detection portion 155f can be respectively provided at both ends of the guide hole 155c formed in the form of an elongated hole. That is, in the moving area of ​​the guide frame 151e, the first cover opening detection portion 155fa can be provided at the end in the direction of opening the discharge cover 222. In addition, in the moving area of ​​the guide frame 151e, the second cover opening detection portion 155fb can be provided at the end in the direction of pushing the protrusion 151 back to its original position.

[0367] Therefore, when the push protrusion 151 moves to a position where it can push the connecting rod 222c to open the exhaust 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 unit 155f can send a signal indicating that the exhaust cover 222 is open. Additionally, when the push protrusion 151 returns to its original position, the guide frame 151e can be positioned at a predetermined position (hereinafter referred to as "cover not open position CP2"), and the cover open detection unit 155f can send a signal indicating that the push protrusion 151 has returned to its original position.

[0368] With this configuration, the cover opening unit 150 can selectively open or close the lower part of the dust collection box 220 by separating the connecting rod 222c from the dust collection box 220. In this case, dust in the dust collection box 220 can be captured into the dust collection section 170 by the impact that occurs when the discharge cover 222 separates from the dust collection box 220.

[0369] Therefore, with the main body 210 of the first cleaner 200 fixed to the connecting portion 120, the cover opening motor 152 can move to push the protrusion 151 to separate the discharge cover 222 from the dust collection box 220. When the discharge cover 222 is separated from the dust collection box 220, the dust in the dust collection box 220 can be captured in the dust collection portion 170.

[0370] Therefore, according to this disclosure, even if the user opens the discharge cover 222 of the first cleaner alone, the cover opening unit 150 can also open the dust collection box 220, thus improving convenience.

[0371] Furthermore, since the discharge cover 222 is open when the first cleaner 200 is connected to the cleaner station 100, dust can be prevented from spreading.

[0372] at the same time, Figure 14 This is a view used to illustrate the relationship between the first cleaner and the pole traction unit in the cleaner station according to an embodiment of the present disclosure.

[0373] The following will refer to Figure 5 , Figure 6 and Figure 14 The pole traction unit 160 is described according to this disclosure.

[0374] The cleaner station 100 according to this disclosure may include a rod traction unit 160. The rod traction unit 160 may be disposed on a first outer wall surface 112a of the housing 110. The rod traction unit 160 may push the dust collection box compression rod 223 of the first cleaner 200 to compress the dust in the dust collection box 220.

[0375] The lever traction unit 160 may include a lever traction arm 161, an arm gear 162, a stroke drive motor 163, a rotation drive motor 164, and an arm motion detection unit 165.

[0376] The lever arm 161 is housed within the housing 110 and can be configured to be both travel-movable and rotatable. For example, the lever arm 161 can be housed in an arm-receiving groove formed in the first outer wall surface 112a. In this case, the dust collection box compression rod 223 can be configured as an imaginary cylinder shape relative to the lower end of the arm-receiving groove.

[0377] The lever traction arm 161 can be configured to push the dust collection box compression lever 223. The lever traction arm 161 can be formed in a shape corresponding to the arm receiving groove. For example, the lever traction arm 161 can be formed in a shape similar to an elongated lever.

[0378] One surface of the lever arm 161 can be formed to define a continuous surface together with the first outer wall surface 112a when the lever arm 161 is received in the arm receiving groove. The arm gear 162 can be coupled to one side of the other surface of the lever arm 161.

[0379] The arm gear 162 can be connected to the lever arm 161, the stroke drive motor 163, and the rotary drive motor 164. For example, the arm gear 162 can be formed as a shaft. One end of the shaft of the arm gear 162 can be fixedly connected to the lever 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 engage with the rotary 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 engage with the stroke drive motor 163.

[0380] The stroke drive motor 163 provides power for the stroke movement of the lever traction arm 161. The stroke drive motor 163 can rotate in either a forward or reverse direction. In this case, the forward direction can refer to the direction in which the lever traction arm 161 moves away from the housing 110 of the cleaner station 100. Conversely, the reverse direction can refer to the direction in which the lever traction arm 161 is pulled towards the cleaner station 100. The forward direction can be the opposite of the reverse direction.

[0381] The rotary drive motor 164 provides power for rotating the lever traction arm 161. The rotary drive motor 164 can rotate in either a forward or reverse direction. In this case, the forward direction refers to the direction in which the lever traction arm 161 rotates to a position where it can push the dust collection box compression lever 223. Furthermore, the reverse direction can be the opposite of the forward direction.

[0382] The stroke drive motor 163 and the rotary drive motor 164 can be housed in the housing 110.

[0383] The arm motion detection unit 165 can be installed in the housing 110. The arm motion detection unit 165 can be installed on the movement path of the arm gear 162 shaft. The arm motion detection unit 165 can be installed at the original position LP1, the maximum stroke movement position LP2, and the position LP3 when the dust collection box compression rod 223 is pulled, respectively.

[0384] The arm motion detection unit 165 may include a contact sensor. For example, the arm motion detection unit 165 may include a microswitch. Simultaneously, the arm motion detection unit 165 may also include a non-contact sensor. For example, the arm motion detection unit 165 may include an infrared (IR) sensor. With this configuration, the arm motion detection unit 165 can detect the travel position of the arm gear 162.

[0385] Additionally, the arm motion detection section 165 can be located at the other end of the shaft of the arm gear 162. The arm motion detection section 165 can be located at the other end of the arm gear 162, which is provided in the form of a worm gear, and can detect rotational position. The arm motion detection section 165 may include a contact sensor. For example, the arm motion detection section 165 may include a microswitch. Simultaneously, the arm motion detection section 165 may also include a non-contact sensor. For example, the arm motion detection section 165 may include an infrared (IR) sensor or a Hall sensor.

[0386] Therefore, the arm motion detection unit 165 can detect that the rod traction arm 161 is located at its original position LP1. Furthermore, the arm motion detection unit 165 can detect that the rod traction arm 161 has moved as far away from the housing 110 (LP2) as possible. Additionally, the arm motion detection unit 165 can detect that the rod traction arm 161 rotates to pull the dust collection box compression rod 223. Furthermore, the arm motion detection unit 165 can detect that the rod traction arm 161 has pulled the dust collection box compression rod 223. Furthermore, the arm motion detection unit 165 can detect that after pulling the dust collection box compression rod 223, the rod traction arm 161 rotates back to its original position.

[0387] Therefore, when the first cleaner 200 is connected to the connecting portion 120, the compression member (not shown) can move downwards as the lever traction arm 161 travels, thereby compressing the dust in the dust collection box 220. In one embodiment of this specification, when the discharge cover 222 is separated from the dust collection box 220, the dust in the dust collection box 220 is mainly captured into the dust separation portion 213 by gravity, and then the residual dust in the dust collection box 220 is partially captured into the dust separation portion 213 by the compression portion 250. Alternatively, when the discharge cover 222 is connected to the dust collection box 220, the compression member (not shown) can compress the dust in the dust collection box 220 downwards, and then the discharge cover 222 can be separated from the dust collection box 220, so that the dust in the dust collection box 220 can be captured into the dust separation portion 213.

[0388] at the same time, Figure 14a Another embodiment of the pole traction unit according to this disclosure is shown.

[0389] To avoid repetitive description, the content related to the rod traction unit 160 according to the embodiments of this disclosure may be used to describe other components besides those specifically mentioned in this embodiment.

[0390] In this embodiment, the arm gear 2162 and the shaft 2166 can be disposed separately, and the arm gear 2162 and the shaft 2166 can be disposed parallel to each other. Furthermore, the shaft 2166 can be connected to be movable relative to the arm gear 2162. 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 connection portion of the shaft 2166.

[0391] Therefore, when the arm gear 2162 rotates by the operation of the stroke drive motor 2163, the shaft 2166 can move along the thread of the arm gear 2162.

[0392] Meanwhile, the lever traction arm 2161 can be located at one end of the shaft 2166, the worm gear 2166a can be located at the other end of the shaft 2166, and the rotary drive motor 2164 can engage with the worm gear 2166a.

[0393] Therefore, when the rotary drive motor 2164 is operated, the shaft 2166 can rotate, and the rod traction arm 2161 can rotate.

[0394] The arm motion detection unit 2165 can be set adjacent to the arm gear 2162 and arranged on the movement path of the shaft 2166. The arm motion detection unit 2165 can be set at the original position LP1, the maximum stroke movement position LP2, and the position LP3 when the dust collection box compression rod 223 is pulled on the shaft 2166.

[0395] That is, the first arm motion detection unit 2165a can be set at the original position LP1 of the shaft. Additionally, the second arm motion detection unit 2165b can be set at the maximum travel position LP2. Furthermore, the third arm motion detection unit 2165c can be set at the position LP3 when the dust collection box compression rod 223 is pulled.

[0396] The arm motion detection unit 2165 may include a contact sensor. For example, the arm motion detection unit 2165 may include a microswitch. Simultaneously, the arm motion detection unit 2165 may also include a non-contact sensor. For example, the arm motion detection unit 2165 may include an infrared (IR) sensor. With this configuration, the arm motion detection unit 2165 can detect the travel position of the shaft 2166.

[0397] Furthermore, the arm motion detection section 2165 may include a fourth arm motion detection section 2165d disposed at the other end of the shaft (worm gear 2166a). The fourth arm motion detection section 2165d can detect the rotational position of the shaft 2166. The fourth arm motion detection section 2165d may include a contact sensor. For example, the fourth arm motion detection section 2165d may include a microswitch. Simultaneously, the fourth arm motion detection section 2165d may also include a non-contact sensor. For example, the fourth arm motion detection section 2165d may include an infrared (IR) sensor or a Hall sensor.

[0398] Therefore, the first arm motion detection unit 2165a can detect that the rod traction arm 2161 is in its original position LP1. Furthermore, the second arm motion detection unit 2165b can detect that the rod traction arm 2161 has moved as far away from the housing 2110 (LP2) as possible. Additionally, the fourth arm motion detection unit 2165d can detect that the rod traction arm 2161 rotates to pull the dust collection box compression rod 223. Furthermore, the third arm motion detection unit 2165c can detect that the rod traction arm 2161 has pulled the dust collection box compression rod 223. Finally, the fourth arm motion detection unit 2165d can detect that after pulling the dust collection box compression rod 223, the rod traction arm 2161 rotates back to its original position.

[0399] Meanwhile, the following will refer to Figure 2 and Figures 15 to 17 Description of the dust collection section 170.

[0400] The cleaning station 100 may include a dust collection section 170. The dust collection section 170 may be disposed within the housing 110. The dust collection section 170 may be disposed on the lower side of the connecting section 120 in the direction of gravity.

[0401] The dust collection section 170 may include a roll of vinyl film (not shown). The roll of vinyl film may be attached to the housing 110 and unrolled downwards by the load of dust falling from the dust collection box 220.

[0402] The cleaner station 100 may include a connector portion (not shown). The connector portion may be disposed within the housing 110. The connector portion may be disposed in the upper region of the dust collection portion 170. The connector portion may cut and engage the upper region of a roll of vinyl film in which dust is captured. Specifically, the connector portion may retract the roll of vinyl film back to a central region and engage the upper region of the roll of vinyl film using a heating wire. The connector portion may include a first connector member (not shown) and a second connector member (not shown). The first connector member (not shown) may be movable along a first direction via a first connector drive portion 174, and the second connector member (not shown) may be movable along a second direction perpendicular to the first direction via a second connector drive portion 175.

[0403] With this configuration, dust captured by the first cleaner 200 or the second cleaner 300 can be collected in a roll of vinyl film, and the roll of vinyl film can be automatically sealed. Therefore, the user does not need to separately tie up the bag containing the dust, thus improving user convenience.

[0404] Meanwhile, the following will refer to Figure 2 and Figures 15 to 17 Describe the flow path section 180.

[0405] The cleaner station 100 may include a flow path section 180. The flow path section 180 may connect a first cleaner 200 or a second cleaner 300 to the dust collection section 170.

[0406] The flow path section 180 may include a first flow path 181, a second flow path 182, and a flow path switching valve 183.

[0407] The first flow path 181 connects the dust collection box 220 of the first cleaner 200 to the dust collection section 170. The first flow path 181 may be located on the rear side of the connecting surface 121. The first flow path 181 may refer to the space between the dust collection box 220 and the dust collection section 170 of the first cleaner 200. The first flow path 181 may be a space formed on the rear side of the dust channel hole 121a. The first flow path 181 may be a flow path that curves downward from the dust channel hole 121a, and dust and air can flow through the first flow path 181. Dust in the dust collection box 220 of the first cleaner 200 can move to the dust collection section 170 through the first flow path 181.

[0408] The second flow path 182 can connect the second cleaner 300 to the dust collection section 170. Dust in the second cleaner 300 can be moved to the dust collection section 170 through the second flow path 182.

[0409] A flow path switching valve 183 may be disposed between the dust collection section 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 collection section 170. Therefore, a decrease in suction force caused by multiple flow paths 181 and 182 being open can be prevented.

[0410] For example, when only the first cleaner 200 is connected to the cleaner station 100, the flow path switching valve 183 can connect the first flow path 181 to the dust collection section 170 and disconnect the second flow path 182 from the dust collection section 170.

[0411] As another example, when only the second cleaner 300 is connected to the cleaner station 100, the flow path switching valve 183 can disconnect the first flow path 181 from the dust collection section 170 and connect the second flow path 182 to the dust collection section 170.

[0412] As another example, when both the first cleaner 200 and the second cleaner 300 are connected to the cleaner station 100, the flow path switching valve 183 can connect the first flow path 181 to the dust collection section 170 and disconnect the second flow path 182 from the dust collection section 170 to first remove dust from the dust collection box 220 of the first cleaner 200. Subsequently, the flow path switching valve 183 can disconnect the first flow path 181 from the dust collection section 170 and connect the second flow path 182 to the dust collection section 170 to remove dust from the second cleaner 300. Therefore, the ease of use for the user manually operating the first cleaner 200 can be improved.

[0413] Meanwhile, the following will refer to Figure 2 and Figures 15 to 17 Description of vacuum module 190.

[0414] The cleaning station 100 may include a vacuum module 190. The vacuum module 190 may include a dust collection motor 191, a first filter 192, and a second filter (not shown).

[0415] A dust collection motor 191 may be disposed below the dust collection section 170. The dust collection motor 191 may generate suction in the first flow path 181 and the second flow path 182. Therefore, the dust collection motor 191 may provide suction capable of drawing dust from the dust collection box 220 of the first cleaner 200 and dust from the second cleaner 300.

[0416] The dust collection motor 191 can generate suction by rotating. For example, the dust collection motor 191 can be formed into a shape similar to a cylinder.

[0417] The first filter 192 may be disposed between the dust collection section 170 and the dust collection motor 191. The first filter 192 may be a pre-filter.

[0418] A second filter (not shown) may be disposed between the dust collection motor 191 and the outer wall surface 112. The second filter (not shown) may be a HEPA filter.

[0419] In this embodiment, the hypothetical balance holding space R1 can extend vertically from the ground and penetrate the dust collection section 170 and the dust collection module 190. For example, the balance holding space R1 can be a hypothetical space extending vertically from the ground, and the dust collection motor 191 can be accommodated at least in the balance holding space R1. That is, the balance holding space R1 can be a hypothetical cylindrical space in which the dust collection motor 191 is accommodated.

[0420] Therefore, the center of gravity of all components located in the balance-maintaining space R1 can be concentrated on the vacuum module 190. In this case, since the vacuum module 190 is positioned close to the ground, the cleaner station 100 can maintain its balance stably, much like a spinning toy.

[0421] With this configuration, in this disclosure, the cleaner station 100 can be stably balanced with the first cleaner 200 installed on the cleaner station 100.

[0422] The cleaner station 100 may include a charging section 128. The charging section 128 may be disposed on the connection section 120. Specifically, the charging section 128 may be disposed on the connection surface 121. In this case, the charging section 128 may be positioned facing the charging terminals disposed on the battery 240 of the first cleaner 200. The charging section 128 may be electrically connected to the first cleaner 200 connected to the connection section 120. The charging section 128 may supply power to the battery of the first cleaner 200 connected to the connection section 120. That is, when the first cleaner 200 is physically connected to the connection surface 121, the charging section 128 may be electrically coupled to the first cleaner 200.

[0423] Additionally, the charging section 128 may include a lower charging section (not shown) disposed in the lower region of the housing 110. The lower charging section may be electrically connected to a second cleaner 300, which is coupled to the lower region of the housing 110. The second charger may supply power to the battery of the second cleaner 300, which is coupled to the lower region of the housing 110.

[0424] The cleaner station 100 may include a side door (not shown). The side door may be disposed within the housing 110. The side door may selectively expose the dust collection section 170 to the outside. Therefore, the user can easily remove the dust collection section 170 from the cleaner station 100.

[0425] at the same time, Figure 17 This is a block diagram illustrating the control configuration of a cleaner station according to an embodiment of the present disclosure.

[0426] The following will refer to Figure 17 Describes the control configuration according to this disclosure.

[0427] The cleaner station 100 according to the present disclosure may further include a control unit 400, which is configured to control the connection part 120, the fixing unit 130, the door unit 140, the cover opening unit 150, the rod traction unit 160, the dust collection part 170, the flow path part 180 and the suction module 190.

[0428] The control unit 400 can be housed in the housing 110.

[0429] The control unit 400 can be disposed on the upper side of the housing 110. For example, the control unit 400 can be disposed on the connecting 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 arranged adjacent to each other, resulting in improved response performance.

[0430] Additionally, the control unit 400 can be disposed on the lower side of the housing 110. For example, the control unit 400 can be disposed within the vacuum module 190. With this arrangement, the control unit 400 can be disposed adjacent to the relatively heavy dust collection motor 191 and close to the ground, allowing the control unit 400 to be stably supported. As a result, even if an external impact is applied to the control unit 400, damage to the control unit 400 can be prevented.

[0431] The control unit 400 may include a printed circuit board and components mounted on the printed circuit board.

[0432] The control unit 400 can determine whether the first cleaner 200 is connected to the cleaner station 100.

[0433] When the user moves the first cleaner 200 to the connection part 120, the dust collection box 220 or battery housing 230 of the first cleaner 200 can detect the predetermined area of ​​the first cleaner 200 via the connection sensor 125. For example, during the process of connecting the first cleaner 200 to the cleaner station 100, the battery housing 230 may come into contact with the connection sensor 125, and the connection sensor 125 can detect the first cleaner 200.

[0434] When the connection sensor 125 detects the connection of the first cleaner 200, the connection sensor 125 can send a signal indicating that the first cleaner 200 is connected to the connection part 120. In this case, the control unit 400 can receive the signal from the connection sensor 125 and determine that the first cleaner 200 is physically connected to the connection part 120.

[0435] Furthermore, when the first cleaner 200 is connected at a precise position on the connecting portion 120, the lower surfaces of the dust collection box 220 and the battery housing 230 can contact the connecting surface 121, and the charging terminals of the charging portion 128 and the charging terminals of the first cleaner 200 can contact each other. In this case, power can be supplied to the battery 240 of the first cleaner 200 through the charging portion 128.

[0436] Therefore, when the charging section 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 connection section 120. Furthermore, the control unit 400 can determine whether the charging section 128 supplies power to the battery 240 of the first cleaner 200, and based on the determination result, check whether the first cleaner 200 is connected at a precise location.

[0437] In this configuration, the control unit 400 can generate a pulse signal by turning the charging voltage supply from the cleaner station 100 to the first cleaner 200 on or off. Therefore, the control unit 400 can send information to the first cleaner 200. For example, the control unit 400 can provide the first cleaner 200 with information instructing it to connect to the cleaner station 100.

[0438] When the control unit 400 determines that the first cleaner 200 is connected to the connecting part 120, the control unit 400 can operate the fixing part motor 133 to fix the first cleaner 200.

[0439] When the fixing member 131 or the fixing part connecting rod 135 moves to the predetermined fixing position FP1, the fixing detection part 137 can send a signal indicating that the first cleaner 200 is fixed. The control unit 400 can 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 can stop the operation of the fixing part motor 133.

[0440] At the same time, when the operation of emptying the dust collection box 220 is finished, the control unit 400 can rotate the fixed part motor 133 in the opposite direction to release the first cleaner 200.

[0441] When the control unit 400 determines that the first cleaner 200 is fixed to the connecting part 120, the control unit 400 can operate the door motor 142 to open the door 141 of the cleaner station 100.

[0442] When door 141 or door arm 143 reaches the predetermined open position DP1, door opening / closing detection unit 144 can send a signal indicating that door 141 is open. Control unit 400 can receive the signal indicating that door 141 is open from door opening / closing detection unit 144 and determine that door 141 is open. When control unit 400 determines that door 141 is open, control unit 400 can stop the operation of door motor 142.

[0443] At the same time, when the operation of emptying the dust collection box 220 is finished, the control unit 400 can rotate the door motor 142 in the opposite direction to close the door 141.

[0444] When the control unit 400 determines that the door 141 is open, the control unit 400 can 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 can communicate with the interior of the dust collection box 220. Therefore, the cleaner station 100 and the first cleaner 200 can be connected to each other to allow fluid to flow (connection of flow paths).

[0445] When the guide frame 151e reaches the predetermined open position CP1, the cover opening detection unit 155f can send a signal indicating that the exhaust cover 222 is open. The control unit 400 can receive the signal indicating that the exhaust cover 222 is open from the cover opening detection unit 155f and determine that the exhaust cover 222 is open. When the control unit 400 determines that the exhaust cover 222 is open, the control unit 400 can stop the operation of the cover opening motor 152.

[0446] The control unit 400 can operate the stroke drive motor 163 and the rotation drive motor 164 to control the lever traction arm 161, so that the lever traction arm 161 can pull the dust collection box compression rod 223.

[0447] When the arm motion detection unit 165 detects that the arm gear 162 has reached the maximum stroke movement position LP2, the arm motion detection unit 165 can send a signal, and the control unit 400 can receive the signal from the arm motion detection unit 165 and stop the operation of the stroke drive motor 163.

[0448] When the arm motion detection unit 165 detects that the arm gear 162 has rotated to a position where the arm gear 162 can pull the dust collection box compression rod 223, the arm motion detection unit 165 can send a signal, and the control unit 400 can receive the signal from the arm motion detection unit 165 and stop the operation of the rotation drive motor 164.

[0449] Additionally, the control unit 400 can operate the stroke drive motor 163 in the opposite direction to pull the arm 161 with a traction rod.

[0450] In this situation, when the arm motion detection unit 165 detects that the arm gear 162 has reached position LP3 when the dust collection box compression rod 223 is pulled, the arm motion detection unit 165 can send a signal, and the control unit 400 can receive the signal from the arm motion detection unit 165 and stop the operation of the stroke drive motor 163.

[0451] Meanwhile, when the operation of emptying the dust collection box 220 is finished, the control unit 400 can rotate the stroke drive motor 163 and the rotation drive motor 164 in the opposite direction to return the rod traction arm 161 to its original position.

[0452] The control unit 400 is operable to engage the first connector drive portion 174 and the second connector drive portion 175 to engage a roll of vinyl film (not shown).

[0453] The control unit 400 can control the flow path switching valve 183 of the flow path section 180. For example, the control unit 400 can selectively open or close the first flow path 181 and the second flow path 182.

[0454] The control unit 400 can operate the dust collection motor 191 to draw in dust from the dust collection box 220.

[0455] The control unit 400 can operate the display unit 500 to display the dust collection box emptying status and charging status of the first cleaner 200 or the second cleaner 300.

[0456] The specific control process of the control unit 400 over time will be described below.

[0457] Additionally, the cleaner station 100 according to this disclosure may include a display unit 500.

[0458] The display unit 500 can be mounted on the housing 110, mounted on a separate display device, or mounted on a terminal such as a mobile phone.

[0459] The display unit 500 can be configured to include at least one of a display panel capable of outputting letters and / or graphics and a speaker capable of outputting voice signals and sounds. The user can easily determine the status of the currently executing process, remaining time, etc., based on the information output through the display unit 500.

[0460] at the same time, Figure 18 This is a flowchart illustrating a method for controlling a cleaning station according to an embodiment of the present disclosure.

[0461] The following will refer to Figures 5 to 18 A method for controlling a cleaning station according to an embodiment of this disclosure is described.

[0462] The method for controlling a cleaning station according to this disclosure includes a connection inspection step S10, a dust collection box fixing step S20, a door opening step S30, a cover opening step S40, a dust collection box compression step S50, a dust collection step S60, an additional dust collection 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.

[0463] In the connection check step S10, it can be checked whether the first cleaner 200 is connected to the connection part 120 of the cleaner station 100.

[0464] Specifically, in the connection check step S10, when the first cleaner 200 is connected, the connection sensor 125 provided on the guide protrusion 123 can contact the battery housing 230, and the connection sensor 125 can send a signal indicating that the first cleaner 200 is connected to the connection portion 120. Alternatively, a non-contact sensor type connection sensor 125 provided on the side wall 124 can detect the presence of the dust collection box 220, and the connection sensor 125 can send a signal indicating that the first cleaner 200 is connected to the connection portion 120. Furthermore, when the connection sensor 125 is provided on the dust collection box guide surface 122, the weight of the dust collection box 220 can push the connection sensor 125, the connection sensor 125 can detect that the first cleaner 200 is connected, and the connection sensor 125 can send a signal indicating that the first cleaner 200 is connected to the connection portion 120.

[0465] Therefore, in the connection check step S10, the control unit 400 can receive the signal generated by the connection sensor 125 and determine that the first cleaner 200 is connected to the connection part 120.

[0466] Meanwhile, in the connection check step S10 according to this disclosure, the control unit 400 can determine whether the first cleaner 200 is connected at a precise location based on whether the charging section 128 supplies power to the battery 240 of the first cleaner 200.

[0467] Therefore, in the connection check step S10, the control unit 400 can receive a signal from the connection sensor 125 indicating that the first cleaner 200 is connected, and check whether the charging part 128 is supplying power to the battery 240, thereby checking whether the first cleaner 200 is connected to the connection part 120 of the cleaner station 100.

[0468] In the dust collection box fixing step S20, when the first cleaner 200 is connected to the cleaner station 100, the fixing member 131 can hold and fix the dust collection box 220.

[0469] Specifically, when the control unit 400 receives a signal from the connection sensor 125 indicating that the first cleaner has been connected, the control unit 400 can operate the fixed part motor 133 in the positive direction, so that the fixed member 131 fixes the dust collection box 220.

[0470] In this case, when the fixing member 131 or the fixing part connecting rod 135 moves to the dust collection box fixing position FP1, the first fixing detection part 137a can send a signal indicating that the first cleaner 200 is fixed.

[0471] Therefore, the control unit 400 can receive a signal indicating that the first cleaner 200 is fixed from the first fixation detection section 137a, and determine that the first cleaner 200 is fixed.

[0472] 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.

[0473] In the door opening step S30, when the dust collection box 220 is fixed, the door 141 can be opened.

[0474] Specifically, when the control unit 400 receives a signal from the first fixed detection section 137a indicating that the dust collection box 220 is fixed, the control unit 400 can operate the door motor 142 in the positive direction to open the dust channel hole 121a.

[0475] In this case, when the door arm 143 moves to the open position DP1 where the first door open / close detection part 144a is provided, the first door open / close detection part 144a can send a signal indicating that the door 141 is open.

[0476] Therefore, the control unit 400 can receive a signal indicating that the door 141 is open from the first door open / close detection section 144a and determine that the door 141 is open.

[0477] When the control unit 400 determines that the door 141 is open, the control unit 400 can stop the operation of the door motor 142.

[0478] In the cover opening step S40, the discharge cover 222 can be opened when the door 141 is opened.

[0479] Specifically, when the control unit 400 receives a signal from the first door opening / closing detection section 144a indicating that the door 141 is open, the control unit 400 can operate the cover opening motor 152 in the forward direction to open the discharge cover 222. That is, the discharge cover 222 can be separated from the dust collection box body 221.

[0480] When the guide frame 151e reaches the predetermined cover opening position CP1 where the first cover opening detection part 155fa is provided, the cover opening detection part 155fa can send a signal indicating that the discharge cover 222 is open.

[0481] In this case, the control unit 400 can receive a signal indicating that the exhaust cover 222 is open from the first cover opening detection section 155fa, and determine that the exhaust cover 222 is open.

[0482] When the control unit 400 determines that the discharge cover 222 is open, the control unit 400 may stop the operation of the cover opening motor 152.

[0483] In the dust collection box compression step S50, when the discharge cover 222 is opened, the interior of the dust collection box 220 can be compressed.

[0484] The dust collection box compression step S50 may include a first compression preparation step S51, a second compression preparation step S52, and a rod traction step S53.

[0485] In the first compression preparation step S51, the lever traction arm 161 or 2161 can travel to the height at which the lever traction arm 161 or 2161 can push the dust collection box compression rod 223.

[0486] Specifically, when the control unit 400 receives a signal from the first cover opening detection section 155fa indicating that the discharge cover 222 is open, the control unit 400 can operate the stroke drive motor 163 or 2163 to move the rod traction arm 161 or 2161 to a height equal to or higher than the height of the dust collection box compression rod 223.

[0487] When the arm motion detection unit 165 or 2165 detects that the lever traction arm 161 or 2161 has moved to a height equal to or higher than the height of the dust collection box compression rod 223, the arm motion detection unit 165 or 2165 can send a signal indicating that the lever traction arm 161 or 2161 has moved to the target position. That is, when the arm motion detection unit 165 or 2165 detects that the arm gear 162 or shaft 2166 has reached the maximum stroke movement position LP2, the arm motion detection unit 165 or 2165 can send a signal. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the operation of the stroke drive motor 163 or 2163.

[0488] In the second compression preparation step S52, the lever traction arm 161 or 2161 can be rotated to a position where the lever traction arm 161 or 2161 can push the dust collection box compression rod 223.

[0489] Specifically, when the control unit 400 receives a signal from the arm motion detection section 165 or 2165 indicating that the indicator rod traction arm 161 or 2161 has moved to a height equal to or higher than the height of the dust collection box compression rod 223, the control unit 400 can operate the rotary 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 collection box compression rod 223.

[0490] When the arm motion detection unit 165 or 2165 detects that the arm gear 162 or shaft 2166 has rotated to a position where the arm gear 162 or shaft 2166 can pull the dust collection box compression rod 223, the arm motion detection unit 165 or 2165 can send a signal indicating that the lever pulls the arm 161 or 2161 to rotate to the target position. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the operation of the rotation drive motor 164 or 2164.

[0491] In the rod traction step S53, the rod traction arm 161 or 2161 can traction the dust collection box compression rod 223 at least once.

[0492] Specifically, after the second compression preparation step S52, the control unit 400 may operate the stroke drive motor 163 or 2163 in the reverse direction to pull the arm 161 or 2161 with the traction rod.

[0493] In this scenario, when the arm motion detection unit 165 or 2165 detects that the arm gear 162 or shaft 2166 has reached position LP3 when the dust collection box compression rod 223 is being pulled, the arm motion detection unit 165 or 2165 can send a signal indicating that the dust collection box compression rod 223 is being pulled. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the operation of the stroke drive motor 163 or 2163.

[0494] In the dust collection box compression step S50, the dust in the dust collection box 220 is pre-compressed before the dust collection motor 191 is operated, which has the effect of preventing residual dust in the dust collection box 220 and improving the dust collection efficiency of the dust collection motor 191.

[0495] In the dust collection step S60, when the discharge cover 222 is opened and the interior of the dust collection box 220 is compressed, the dust collection motor 191 is operable to collect dust from the dust collection box 220.

[0496] Specifically, when the control unit 400 receives a signal from the first cover opening detection section 155fa indicating that the discharge cover 222 is open and from the arm movement detection section 165 or 2165 indicating that the dust collection box compression rod 223 is being pulled, the control unit 400 can operate the dust collection motor 191.

[0497] In the dust collection step S60, dust in the dust collection box 220 can pass through the dust channel hole 121a and the first flow path 181, and then be collected in the dust collection section 170. Therefore, the user can remove the dust in the dust collection box 220 without separate operation, thus providing convenience for the user.

[0498] In the additional dust collection box compression step S70, the interior of the dust collection box 220 can be compressed during the operation of the dust collection motor 191.

[0499] Specifically, after the rod traction step S53, the control unit 400 can operate the stroke drive motor 163 or 2163 in the forward direction to move the rod traction arm 161 or 2161 to height LP2 before traction of the dust collection box compression rod 223. In this case, the dust collection box compression rod 223 also returns to its original position via an elastic member (not shown).

[0500] In other words, when the arm gear 162 or shaft 2166 reaches the maximum travel position LP2 again, the arm motion detection unit 165 or 2165 can send a signal. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the forward operation of the travel drive motor 163 or 2163.

[0501] Subsequently, immediately after the dust collection motor 191 operates or after a predetermined time has elapsed since the dust collection motor 191 operates, the control unit 400 may operate the stroke drive motor 163 or 2163 in the reverse direction to pull the dust collection box compression rod 223.

[0502] Simultaneously, the additional dust collection box compression step S70 can be performed at least once. In this case, the number of times the additional dust collection box compression step S70 is performed can be preset, or the user can input the number through an input section (not shown). Alternatively, the control unit 400 can automatically set the number of times by detecting the amount of dust in the dust collection box 220 using sensors or the like.

[0503] In the additional dust collection box compression step S70, since the dust in the dust collection box 220 is compressed during the operation of the dust collection motor 191, the effect of removing residual dust exists even during the operation of the dust collection motor 191.

[0504] In the dust collection end step S80, the operation of the dust collection motor 191 can end when the dust collection motor 191 has been operating for a predetermined time.

[0505] Specifically, the control unit 400 may embed a timer (not shown), and when the control unit 400 determines that a predetermined time has elapsed, it may terminate the operation of the dust collection motor 191.

[0506] In this case, the operating time of the dust collection motor 191 can be preset, or the user can input the operating time through an input section (not shown). Alternatively, the control unit 400 can automatically set the operating time by detecting the amount of dust in the dust collection box 220 using sensors or the like.

[0507] In the door closing step S90, door 141 can be closed after the dust collection end step S80.

[0508] Specifically, after the control unit 400 stops the operation of the dust collection motor 191, the control unit 400 can operate the door motor 142 in the reverse direction to close at least a portion of the dust passage opening 121a. That is, in the door closing step S90, the dust collection operation from the dust collection box 220 ends, and then the door 141 can be rotated to close the dust passage opening 121a. In this case, the discharge cover 222 supported by the door 141 can be rotated and secured to the dust collection box body 221, so that the lower side of the dust collection box body 221 can be closed.

[0509] In this case, when the door arm 143 moves to the closed position DP2 where the second door opening / closing detection part 144b is provided, the second door opening / closing detection part 144b can send a signal indicating that the door 141 is closed.

[0510] Therefore, the control unit 400 can receive a signal indicating that the door 141 is closed from the second door open / close detection section 144b, and determine that the door 141 is closed.

[0511] When the control unit 400 determines that the door 141 is closed, the control unit 400 can stop the operation of the door motor 142.

[0512] With this configuration, after the dust collection operation from the dust collection box 220 is completed, the cleaner station 100 can automatically close its door 141 and simultaneously close the discharge cover 222 of the dust collection 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 internal space of the dust collection box 220.

[0513] In the compression end step S100, the lever arm can return to its original position after the door closing step S90.

[0514] The compression end step S100 may include a first return step S101 and a second return step S102.

[0515] In the first return step S101, the lever arm 161 or 2161 can be rotated back to its original position.

[0516] Specifically, when the control unit 400 receives a signal from the second door opening / closing detection section 144b indicating that the door 141 is closed, the control unit 400 may operate the rotary drive motor 164 or 2164 in the opposite direction to move the lever arm 161 or 2161 to its original position.

[0517] When the arm motion detection unit 165 or 2165 detects that the arm gear 162 or shaft 2166 has rotated the dust collection box compression rod 223 to its original position, the arm motion detection unit 165 or 2165 can send a signal indicating that the indicator rod traction arm 161 or 2161 has rotated to the target position. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the operation of the rotation drive motor 164 or 2164.

[0518] In the second return step S102, the lever arm 161 or 2161 can travel back to its original position.

[0519] Specifically, when the control unit 400 receives a signal indicating that the lever traction arm 161 or 2161 has rotated to the target position, the control unit 400 can operate the stroke drive motor 163 or 2163 in the opposite direction to move the lever traction arm 161 or 2161 to the original position (position LP1 where the lever traction arm 161 or 2161 is connected to the housing 110).

[0520] When the arm motion detection unit 165 or 2165 detects that the lever traction arm 161 or 2161 has moved to its original position, the arm motion detection unit 165 or 2165 can send a signal indicating that the lever traction arm 161 or 2161 has moved to the target position. That is, when the arm motion detection unit 165 or 2165 detects that the arm gear 162 or shaft 2166 has reached the original position LP1, the arm motion detection unit 165 or 2165 can send a signal. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the operation of the stroke drive motor 163 or 2163.

[0521] In the release step S110, when the door 141 is closed, the fixed part motor 133 can be operated so that the fixed member 131 can release the dust collection box 220.

[0522] Specifically, when the control unit 400 receives a signal from the arm motion detection section 165 or 2165 indicating that the arm gear has reached the original position LP1, the control unit 400 can operate the fixed section motor 133 in the opposite direction to release the dust collection box 220.

[0523] In this case, when the fixing member 131 or the fixing part connecting rod 135 moves to the dust collection box release position FP2, the second fixing detection part 137b can send a signal indicating that the first cleaner 200 has been released.

[0524] Therefore, the control unit 400 can receive a signal indicating that the first cleaner 200 has been released from the second fixed detection section 137b, and determine that the first cleaner 200 has been released.

[0525] When the control unit 400 determines that the first cleaner 200 has been released, the control unit 400 may stop the operation of the fixed part motor 133.

[0526] 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 collection 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 collection box 220 is blocked, so that the dust collection box 220 can be released and the user can separate the first cleaner 200 from the cleaner station 100.

[0527] at the same time, Figure 19This is a flowchart illustrating a second embodiment of the method for controlling a cleaning station according to the present disclosure.

[0528] The following will refer to Figures 5 to 19 A method for controlling a cleaning station according to a second embodiment of this disclosure is described.

[0529] The method for controlling the cleaning station according to this embodiment includes a connection inspection step S10, a dust collection box fixing step S20, a door opening step S30, a cover opening step S40, a dust collection step S60, a dust collection 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.

[0530] To avoid repetition, the content related to the method of controlling the cleaning station according to the foregoing embodiments of this disclosure can be used to describe the connection inspection step S10, dust collection box fixing step S20, door opening step S30, cover opening step S40, dust collection end step S80, door closing step S90, compression end step S100 and release step S110 according to the second embodiment.

[0531] In this embodiment, the dust collection step S60 can be performed after the cover opening step S40.

[0532] Specifically, in the dust collection step S60, when the discharge cover 222 is opened, the dust collection motor 191 is operable to collect dust from the dust collection box 220.

[0533] Specifically, when the control unit 400 receives a signal from the first cover opening detection section 155fa indicating that the discharge cover 222 is open, the control unit 400 can operate the dust collection motor 191.

[0534] In the dust collection step S60, dust in the dust collection box 220 can pass through the dust channel hole 121a and the first flow path 181, and then be collected in the dust collection section 170. Therefore, the user can remove the dust in the dust collection box 220 without separate operation, thus providing convenience for the user.

[0535] Furthermore, in the dust collection box compression step S70' according to this embodiment, the dust collection box 220 can be compressed during the operation of the dust collection motor 191.

[0536] The dust collection box compression step S70' may include a first compression preparation step S71', a second compression preparation step S72', a rod traction step S73', and an additional traction step S74'.

[0537] In this case, the first compression preparation step S71' and the second compression preparation step S72' can be performed after the operation of the dust collection motor 191 or before the operation of the dust collection motor 191.

[0538] In the first compression preparation step S71', the lever traction arm 161 or 2161 can travel to the height at which the lever traction arm 161 or 2161 can push the dust collection box compression rod 223.

[0539] Specifically, the control unit 400 can operate the stroke drive motor 163 or 2163 to move the rod traction arm 161 or 2161 to a height equal to or higher than the height of the dust collection box compression rod 223.

[0540] When the arm motion detection unit 165 or 2165 detects that the lever traction arm 161 or 2161 has moved to a height equal to or higher than the height of the dust collection box compression rod 223, the arm motion detection unit 165 or 2165 can send a signal indicating that the lever traction arm 161 or 2161 has moved to the target position. That is, when the arm motion detection unit 165 or 2165 detects that the arm gear 162 or shaft 2166 has reached the maximum stroke movement position LP2, the arm motion detection unit 165 or 2165 can send a signal. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the operation of the stroke drive motor 163 or 2163.

[0541] In the second compression preparation step S72', the lever traction arm 161 or 2161 can be rotated to a position where the lever traction arm 161 or 2161 can push the dust collection box compression rod 223.

[0542] Specifically, when the control unit 400 receives a signal from the arm motion detection section 165 or 2165 indicating that the indicator rod traction arm 161 or 2161 has moved to a height equal to or higher than the height of the dust collection box compression rod 223, the control unit 400 can operate the rotary 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 collection box compression rod 223.

[0543] When the arm motion detection unit 165 or 2165 detects that the arm gear 162 or shaft 2166 has rotated to a position where the arm gear 162 or shaft 2166 can pull the dust collection box compression rod 223, the arm motion detection unit 165 or 2165 can send a signal indicating that the lever pulls the arm 161 or 2161 to rotate to the target position. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the operation of the rotation drive motor 164 or 2164.

[0544] In the rod traction step S73', the rod traction arm 161 or 2161 can traction the dust collection box compression rod 223 at least once.

[0545] Specifically, after the second compression preparation step S72', the control unit 400 can operate the stroke drive motor 163 or 2163 in the reverse direction to pull the arm 161 or 2161 with the traction rod.

[0546] In this scenario, when the arm motion detection unit 165 or 2165 detects that the arm gear 162 or shaft 2166 has reached position LP3 when the dust collection box compression rod 223 is being pulled, the arm motion detection unit 165 or 2165 can send a signal indicating that the dust collection box compression rod 223 is being pulled. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the operation of the stroke drive motor 163 or 2163.

[0547] In the additional traction step S74', the rod traction arm 161 or 2161 can be used to attach the traction dust collection box compression rod 223.

[0548] In this case, whether to perform the additional traction step S74' and the number of times to perform the additional traction step S74' can be preset, or the user can input whether to perform the additional traction step S74' and the number of times to perform the additional traction step S74' through an input section (not shown). Alternatively, the control unit 400 can use sensors or the like to detect the amount of dust in the dust collection box 220 and automatically set whether to perform the additional traction step S74' and the number of times to perform the additional traction step S74'.

[0549] After the rod traction step S73', the control unit 400 can operate the stroke drive motor 163 or 2163 in the forward direction to move the rod traction arm 161 or 2161 to height LP2 before traction of the dust collection box compression rod 223. In this case, the dust collection box compression rod 223 also returns to its original position via an elastic member (not shown).

[0550] In other words, when the arm gear 162 or shaft 2166 reaches the maximum travel position LP2 again, the arm motion detection unit 165 or 2165 can send a signal. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the forward operation of the travel drive motor 163 or 2163.

[0551] Subsequently, immediately after the dust collection motor 191 operates or after a predetermined time has elapsed since the dust collection motor 191 operates, the control unit 400 may operate the stroke drive motor 163 or 2163 in the reverse direction to pull the dust collection box compression rod 223.

[0552] According to this embodiment, since the dust collection box compression rod 223 is pulled an appropriate number of times during the operation of the dust collection motor 191, the time spent emptying the dust collection box 220 is reduced.

[0553] at the same time, Figure 20 This is a flowchart illustrating a third embodiment of a method for controlling a cleaning station according to the present disclosure.

[0554] The following will refer to Figures 5 to 20 A method for controlling a cleaning station according to a third embodiment of this disclosure is described.

[0555] The method for controlling the cleaning station according to this embodiment includes a connection inspection step S10, a dust collection box fixing step S20, a door opening step S30, a cover opening step S40, a dust collection box compression step S50', a dust collection step S60, a dust collection end step S80, a door closing step S90, a compression end step S100, and a release step S110.

[0556] To avoid repetition, the content related to the method of controlling the cleaning station according to the foregoing embodiments of this disclosure can be used to describe the connection inspection step S10, dust collection box fixing step S20, door opening step S30, cover opening step S40, dust collection end step S80, door closing step S90, compression end step S100 and release step S110 according to the third embodiment.

[0557] The dust collection box compression step S50' may include a first compression preparation step S51', a second compression preparation step S52', a rod traction step S53', and an additional traction step S54'.

[0558] In the first compression preparation step S51', 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 move the stroke of the rod traction arm 161 or 2161 to the height at which the rod traction arm 161 or 2161 can push the dust collection box compression rod 223.

[0559] Specifically, the control unit 400 can operate the stroke drive motor 163 or 2163 to move the rod traction arm 161 or 2161 to a height equal to or higher than the height of the dust collection box compression rod 223.

[0560] When the arm motion detection unit 165 or 2165 detects that the lever traction arm 161 or 2161 has moved to a height equal to or higher than the height of the dust collection box compression rod 223, the arm motion detection unit 165 or 2165 can send a signal indicating that the lever traction arm 161 or 2161 has moved to the target position. That is, when the arm motion detection unit 165 or 2165 detects that the arm gear 162 or shaft 2166 has reached the maximum stroke movement position LP2, the arm motion detection unit 165 or 2165 can send a signal. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the operation of the stroke drive motor 163 or 2163.

[0561] In the second compression preparation step S52', the lever traction arm 161 or 2161 can be rotated to a position where the lever traction arm 161 or 2161 can push the dust collection box compression rod 223.

[0562] Specifically, when the control unit 400 receives a signal from the arm motion detection section 165 or 2165 indicating that the indicator rod traction arm 161 or 2161 has moved to a height equal to or higher than the height of the dust collection box compression rod 223, the control unit 400 can operate the rotary 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 collection box compression rod 223.

[0563] When the arm motion detection unit 165 or 2165 detects that the arm gear 162 or shaft 2166 has rotated to a position where the arm gear 162 or shaft 2166 can pull the dust collection box compression rod 223, the arm motion detection unit 165 or 2165 can send a signal indicating that the lever pulls the arm 161 or 2161 to rotate to the target position. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the operation of the rotation drive motor 164 or 2164.

[0564] In the rod traction step S53', the rod traction arm 161 or 2161 can traction the dust collection box compression rod 223 at least once.

[0565] Specifically, after the second compression preparation step S52', the control unit 400 can operate the stroke drive motor 163 or 2163 in the reverse direction to pull the arm 161 or 2161 with the traction rod.

[0566] In this scenario, when the arm motion detection unit 165 or 2165 detects that the arm gear 162 or shaft 2166 has reached position LP3 when the dust collection box compression rod 223 is being pulled, the arm motion detection unit 165 or 2165 can send a signal indicating that the dust collection box compression rod 223 is being pulled. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the operation of the stroke drive motor 163 or 2163.

[0567] In the additional traction step S54', the rod traction arm 161 or 2161 can be used to attach the traction dust collection box compression rod 223.

[0568] In this case, whether to perform the additional traction step S54' and the number of times to perform the additional traction step S54' can be preset, or the user can input whether to perform the additional traction step S54' and the number of times to perform the additional traction step S54' through an input section (not shown). Alternatively, the control unit 400 can use sensors or the like to detect the amount of dust in the dust collection box 220 and automatically set whether to perform the additional traction step S54' and the number of times to perform the additional traction step S54'.

[0569] After the rod traction step S53', the control unit 400 can operate the stroke drive motor 163 or 2163 in the forward direction to move the rod traction arm 161 or 2161 to height LP2 before traction of the dust collection box compression rod 223. In this case, the dust collection box compression rod 223 also returns to its original position via an elastic member (not shown).

[0570] In other words, when the arm gear 162 or shaft 2166 reaches the maximum travel position LP2 again, the arm motion detection unit 165 or 2165 can send a signal. The control unit 400 can receive the signal from the arm motion detection unit 165 or 2165 and stop the forward operation of the travel drive motor 163 or 2163.

[0571] Subsequently, immediately after the dust collection motor 191 operates or after a predetermined time has elapsed since the dust collection motor 191 operates, the control unit 400 may operate the stroke drive motor 163 or 2163 in the reverse direction to pull the dust collection box compression rod 223.

[0572] In this embodiment, the dust collection step S60 is performed after the dust collection box compression step S50'.

[0573] Therefore, in the dust collection step S60, when the discharge cover 222 is opened and the interior of the dust collection box 220 is compressed a preset number of times, the dust collection motor 191 can be operated to collect dust from the dust collection box 220.

[0574] According to this embodiment, since the dust collection motor 191 operates after the dust collection box compression rod 223 has been pulled an appropriate number of times, it has the effect of reducing the time spent emptying the dust collection box 220.

[0575] at the same time, Figure 21 This is a flowchart illustrating a fourth embodiment of a method for controlling a cleaning station according to the present disclosure.

[0576] The following will refer to Figures 5 to 21 A method for controlling a cleaning station according to a fourth embodiment of the present disclosure is described.

[0577] The method for controlling the cleaning station according to this embodiment includes a connection inspection step S10, a dust collection box fixing step S20, a door opening step S30, a cover opening step S40, a dust collection step S60, a dust collection end step S80, a door closing step S90, a compression end step S100, and a release step S110.

[0578] This embodiment can be applied when a first cleaner without a dust collection box compression rod 223 is connected to the cleaner station 100 or when the dust collection box needs to be emptied quickly.

[0579] Whether to apply this embodiment can be preset or input by the user through an input section (not shown). Alternatively, whether to apply this embodiment can be automatically set by the control unit 400 based on the presence or absence of the dust collection box compression rod 223 detected by sensors or the like.

[0580] In this embodiment, the step of compressing the dust collection box 220 is omitted, which allows the dust collection box 220 to be emptied as quickly as possible.

[0581] Although this disclosure has been described with reference to specific embodiments, these embodiments are for illustrative purposes only and are not limited to these embodiments. It is obvious that those skilled in the art can modify or alter this disclosure without departing from its technical spirit.
