The present disclosure relates to a cleaner station, and more particularly, to a cleaner station configured to draw dust, stored in a cleaner, into the cleaner station.
In general, a cleaner refers to an electrical appliance that draws in small garbage or dust by sucking air using electricity and fills a dust bin provided in a product with the garbage or dust. Such a cleaner is generally called a vacuum cleaner.
The cleaners may be classified into a manual cleaner which is moved directly by a user to perform a cleaning operation, and an automatic cleaner which performs a cleaning operation while autonomously traveling. Depending on the shape of the cleaner, the manual cleaners may be classified into a canister cleaner, an upright cleaner, a handy cleaner, a stick cleaner, and the like.
The canister cleaners were widely used in the past as household cleaners. However, recently, there is an increasing tendency to use the handy cleaner and the stick cleaner in which a dust bin and a cleaner main body are integrally provided to improve convenience of use.
In the case of the canister cleaner, a main body and a suction port are connected by a rubber hose or pipe, and in some instances, the canister cleaner may be used in a state in which a brush is fitted into the suction port.
The handy cleaner (hand vacuum cleaner) has maximized portability and is light in weight. However, because the handy cleaner has a short length, there may be a limitation to a cleaning region. Therefore, the handy cleaner is used to clean a local place such as a desk, a sofa, or an interior of a vehicle.
A user may use the stick cleaner while standing and thus may perform a cleaning operation without bending his/her waist. Therefore, the stick cleaner is advantageous for the user to clean a wide region while moving in the region. The handy cleaner may be used to clean a narrow space, whereas the stick cleaner may be used to clean a wide space and also used to a high place that the user's hand cannot reach. Recently, modularized stick cleaners are provided, such that types of cleaners are actively changed and used to clean various places.
In addition, recently, a robot cleaner, which autonomously performs a cleaning operation without a user's manipulation, is used. The robot cleaner automatically cleans a zone to be cleaned by sucking foreign substances such as dust from the floor while autonomously traveling in the zone to be cleaned.
To this end, the robot cleaner includes a distance sensor configured to detect a distance from an obstacle such as furniture, office supplies, or walls installed in the zone to be cleaned, and left and right wheels for moving the robot cleaner.
In this case, the left wheel and the right wheel are configured to be rotated by a left wheel motor and a right wheel motor, respectively, and the robot cleaner cleans the room while autonomously changing its direction by operating the left wheel motor and the right wheel motor.
However, because the handy cleaner, the stick cleaner, or the robot cleaner in the related art has a dust bin with a small capacity for storing collected dust, which inconveniences the user because the user needs to empty the dust bin frequently.
In addition, because the dust scatters during the process of emptying the dust bin, there is a problem in that the scattering dust has a harmful effect on the user's health.
In addition, if residual dust is not removed from the dust bin, there is a problem in that a suction force of the cleaner deteriorates.
In addition, if the residual dust is not removed from the dust bin, there is a problem in that the residual dust causes an offensive odor.
Patent Document US 2020-0129025 A1 discloses a dust bin to be combined with a stick vacuum cleaner.
In the case of the combination of the dust bin and the vacuum cleaner in Patent Document US 2020-0129025 A1, a sealing member may correspond to a size of a dust outlet and be disposed to surround the dust outlet.
In Patent Document US 2020-0129025 A1, the sealing member is fixedly disposed on a dust inlet port to seal a portion between the dust bin and a cup body of the vacuum cleaner.
With this configuration, a gap between the dust bin and the vacuum cleaner may be sealed when a user inserts the dust bin into the vacuum cleaner.
However, the configuration disclosed in Patent Document US 2020-0129025 A1 is inconvenient for the user because the user needs to push the vacuum cleaner to the dust bin by applying a force to seal the gap between the dust bin and the vacuum cleaner.
In addition, Patent Document US 2020-0129025 A1 merely discloses the sealing member used to seal the gap between the vacuum cleaner and the dust bin, but the configuration thereof cannot prevent the separation between the vacuum cleaner and the dust bin or prevent the sway of the vacuum cleaner that may occur during the process of fixing the vacuum cleaner and removing the dust.
Meanwhile, Patent Document U.S. Pat. No. 10,595,692 B2 discloses a discharge station having a debris bin of a robot cleaner.
In Patent Document U.S. Pat. No. 10,595,692 B2, a station to which the robot cleaner is docked is provided, and a seal is provided to seal a portion between a discharge port of the robot cleaner and an inlet port of a station.
The seal disclosed in Patent Document U.S. Pat. No. 10,595,692 B2 merely seals the portion between the discharge port of the robot cleaner and the inlet port of the station when the discharge port of the robot cleaner and the inlet port of the station are pressed by the weight of the robot cleaner. However, the configuration of Patent Document U.S. Pat. No. 10,595,692 B2 cannot recognize the coupling of the cleaner nor perform the sealing while fixing the cleaner.
Meanwhile, Patent Document KR 2020-0037199 A discloses a cleaner.
Patent Document KR 2020-0037199 A discloses the cleaner capable of compressing dust in a dust bin and removing the dust.
The advantage of the cleaner disclosed in Patent Document KR 2020-0037199 A is that an operating unit operates to compress the inside of the dust bin, thereby effectively removing the dust in the dust bin.
However, the cleaner cannot compress the inside of the dust bin without a user's separate manipulation.
Moreover, even though the inside of the dust bin is compressed by the manipulation of the operating unit of the cleaner, the cleaner is inclined toward one side and falls down or the station mounted with the cleaner falls down unless the user fixes the cleaner with a separate manipulation.
Meanwhile, Patent Document KR 2020-0074054 A discloses a vacuum cleaner and a docking station.
In the vacuum cleaner, a dust collecting container has a discharge port through which air is discharged, and the docking station includes an opening/closing device configured to open or close the discharge port.
However, the opening/closing device serves to block the discharge port to prevent an inflow of outside air but does not serve to seal a portion between a dust bin and a station.
Therefore, there is a need to develop a structure capable of fixing a cleaner to a station while sealing a portion between the cleaner and the station.
The present disclosure has been made in an effort to solve the above-mentioned problems in the related art, and an object of the present disclosure is to provide a cleaner station capable of eliminating inconvenience caused because a user needs to empty a dust bin all the time.
Another object of the present disclosure is to provide a cleaner station capable of preventing dust from scattering when emptying a dust bin.

The coupling part may further include a fixing member entrance hole formed in the form of a long hole along a sidewall so that the fixing member enters and exits the fixing member entrance hole.
The fixing unit may further include a guide frame coupled to the housing and configured to penetrate the movable panel and guide a movement of the fixing member.
The connection projection may have a frame through hole that may be penetrated by the guide frame.
The cleaner station according to the present disclosure may further include a charging part configured to supply power to the cleaner; and a control unit configured to control the coupling part, the charging part, and the fixing unit.
The coupling part may further include a coupling sensor configured to detect whether the cleaner is coupled.
The control unit may operate the fixing part motor when the control unit receives, from the coupling sensor, a signal indicating a coupled state of the cleaner.
The control unit may operate the fixing part motor when power is applied to a battery of the cleaner through the charging part.
When the coupling sensor detects the cleaner and the power is applied to the battery of the cleaner through the charging part, the control unit may determine that the cleaner is coupled to the coupling part.
In a cleaner station according to another embodiment of the present disclosure, the fixing member may include a rotary sealer provided to surround the cleaner by being pressed by the cleaner when the cleaner is coupled to the coupling part.
The rotary sealer may include a coupling part rotatably coupled to the coupling part.
According to the cleaner station according to the present disclosure, it is possible to eliminate the inconvenience caused because the user needs to empty the dust bin all the time.
In addition, since the dust in the dust bin is sucked into the station when emptying the dust bin, it is possible to prevent the dust from scattering.
In addition, it is possible to open the dust passing hole by detecting coupling of the cleaner without the user's separate manipulation and remove the dust in the dust bin in accordance with the operation of the dust collecting motor, and as a result, it is possible to provide convenience for the user.
In addition, a stick cleaner and a robot cleaner may be coupled to the cleaner station at the same time, and as necessary, the dust in the dust bin of the stick cleaner and the dust in the dust bin of the robot cleaner may be selectively removed.
In addition, when the cleaner station detects the coupling of the dust bin, the lever is pulled to compress the dust bin, such that the residual dust does not remain in the dust bin, and as a result, it is possible to increase the suction force of the cleaner.
Further, it is possible to remove an offensive odor caused by the residual dust by preventing the residual dust from remaining in the dust bin.
In addition, the cleaner may be mounted on the cleaner station in the state in which the extension tube and the cleaning module are mounted.
In addition, it is possible to minimize an occupied space on a horizontal plane even in the state in which the cleaner is mounted on the cleaner station.
In addition, because the flow path, which communicates with the dust bin, is bent downward only once, it is possible to minimize a loss of flow force for collecting the dust.
In addition, the dust in the dust bin is invisible from the outside in the state in which the cleaner is mounted on the cleaner station.
In addition, the cleaner station automatically detects the coupled state of the cleaner and fixes the dust bin of the cleaner at the time of coupling the cleaner to the station, which makes it possible to seal the cleaner without applying a separate force.
In addition, the cleaner station automatically detects the coupled state of the cleaner and seals the cleaner at the time of coupling the cleaner to the station, which makes it possible to improve the efficiency in preventing the dust from scattering.

Referring to
The dust removing system 10 may include the cleaner station 100. The first cleaner 200 and the second cleaner 300 may be disposed on the cleaner station 100. The first cleaner 200 may be coupled to a lateral surface of the cleaner station 100. Specifically, a main body of the first cleaner 200 may be coupled to the lateral surface of the cleaner station 100. The second cleaner 200 may be coupled to a lower portion of the cleaner station 100. The cleaner station 100 may remove dust from a dust bin 220 of the first cleaner 200. The cleaner station 100 may remove dust from a dust bin (not illustrated) of the second cleaner 300.
Meanwhile,
First, in order to assist in understanding the cleaner station 100 according to the present disclosure, a structure of the first cleaner 200 will be described below with reference to
The first cleaner 200 may mean a cleaner configured to be manually operated by a user. For example, the first cleaner 200 may mean a handy cleaner or a stick cleaner.
The first cleaner 200 may be mounted on the cleaner station 100. The first cleaner 200 may be supported by the cleaner station 100. The first cleaner 200 may be coupled to the cleaner station 100.
The first cleaner 200 may include a main body 210. The main body 210 may include a main body housing 211, a suction part 212, a dust separating part 213, a suction motor 214, an air discharge cover 215, a handle 216, an extension part 217, and an operating part 218.
The main body housing 211 may define an external appearance of the first cleaner 200. The main body housing 211 may provide a space that may accommodate therein the suction motor 214 and a filter (not illustrated). The main body housing 211 may be formed in a shape similar to a cylindrical shape.
The suction part 212 may protrude outward from the main body housing 211. For example, the suction part 212 may be formed in a cylindrical shape with an opened inside. The suction part 212 may communicate with an extension tube 250. The suction part 212 may be referred to as a flow path (hereinafter, referred to as a ‘suction flow path’) through which air containing dust may flow.
Meanwhile, in the present embodiment, an imaginary centerline may be defined to penetrate a center of the cylindrical suction part 212. That is, an imaginary suction flow path centerline a2 may be formed to pass through the center of the suction flow path.
The dust separating part 213 may communicate with the suction part 212. The dust separating part 213 may separate dust introduced into the dust separating part 213 through the suction part 212. The dust separating part 213 may communicate with the dust bin 220.
For example, the dust separating part 213 may be a cyclone part capable of separating dust using a cyclone flow. Further, the dust separating part 213 may communicate with the suction part 212. Therefore, the air and the dust, which are introduced through the suction part 212, spirally flow along an inner circumferential surface of the dust separating part 213. Therefore, the cyclone flow may be generated about a central axis of the dust separating part 213.
Meanwhile, in the present embodiment, the center axis of the cyclone part may be an imaginary cyclone center axis a4 extending in a vertical direction.
The suction motor 214 may generate a suction force for sucking air. The suction motor 214 may be accommodated in the main body housing 211. The suction motor 214 may generate the suction force by means of a rotation. For example, the suction motor 214 may be formed in a shape similar to a cylindrical shape.
Meanwhile, in the present embodiment, the imaginary motor axis a1 may be formed by extending a center axis of the suction motor 214.
The air discharge cover 215 may be disposed at one side in an axial direction of the main body housing 211. The air discharge cover 215 may accommodate a filter for filtering air. For example, an HEPA filter may be accommodated in the air discharge cover 215.
The air discharge cover 215 may have an air discharge port 215a for discharging the air introduced by the suction force of the suction motor 214.
A flow guide may be disposed on the air discharge cover 215. The flow guide may guide a flow of the air to be discharged through the air discharge port 215a.
The handle 216 may be grasped by the user. The handle 216 may be disposed at a rear side of the suction motor 214. For example, the handle 216 may be formed in a shape similar to a cylindrical shape. Alternatively, the handle 216 may be formed in a curved cylindrical shape. The handle 216 may be disposed at a predetermined angle with respect to the main body housing 211, the suction motor 214, or the dust separating part 213.
Meanwhile, in the present embodiment, an imaginary handle axis a3 may be formed by extending a center axis of the handle 216.
A shaft of the suction motor 214 may be disposed between the suction part 212 and the handle 216.
That is, the motor axis a1 may be disposed between the suction part 212 and the handle 216.
Further, the handle axis a3 may be disposed at a predetermined angle with respect to the motor axis a1 or the suction flow path centerline a2. Therefore, there may be an intersection point at which the handle axis a3 intersects the motor axis a1 or the suction flow path centerline a2.
Meanwhile, the motor axis a1, the suction flow path centerline a2, and the handle axis a3 may be disposed on the same plane S1.
With this configuration, the centers of gravity of the entire first cleaner 200 according to the present disclosure may be disposed symmetrically with respect to the plane S1.
Meanwhile, in the embodiment of the present disclosure, a forward direction may mean a direction in which the suction part 212 is disposed based on the suction motor 214, and a rear direction may mean a direction in which the handle 216 is disposed.
An upper surface of the handle 216 may define an external appearance of apart of an upper surface of the first cleaner 200. Therefore, it is possible to prevent a component of the first cleaner 200 from coming into contact with the user's arm when the user grasps the handle 216.
The extension part 217 may extend from the handle 216 toward the main body housing 211. At least a part of the extension part 217 may extend in a horizontal direction.
The operating part 218 may be disposed on the handle 216. The operating part 218 may be disposed on an inclined surface formed in an upper region of the handle 216. The user may input an instruction to operate or stop the first cleaner 200 through the operating part 218.
The first cleaner 200 may include the dust bin 220. The dust bin 220 may communicate with the dust separating part 213. The dust bin 220 may store the dust separated by the dust separating part 213.
The dust bin 220 may include a dust bin main body 221, a discharge cover 222, a dust bin compression lever 223, and a compression member 224.
The dust bin main body 221 may provide a space capable of storing the dust separated from the dust separating part 213. For example, the dust bin main body 221 may be formed in a shape similar to a cylindrical shape.
Meanwhile, in the present embodiment, an imaginary dust bin axis a5 may be formed by extending a center axis of the dust bin main body 221. For example, the dust bin axis a5 may be disposed coaxially with the motor axis a1. Therefore, the dust bin axis a5 may also be disposed on the plane S1 including the motor axis a1, the suction flow path centerline a2, and the handle axis a3.
A part of a lower side of the dust bin main body 221 may be opened. In addition, a lower extension portion 221a may be formed at the lower side of the dust bin main body 221. The lower extension portion 221a may be formed to block a part of the lower side of the dust bin main body 221.
The dust bin 220 may include a discharge cover 222. The discharge cover 222 may be disposed at a lower side of the dust bin 220. The discharge cover 222 may selectively open or close the lower side of the dust bin 220 which is opened downward.
The discharge cover 222 may include a cover main body 222a, a hinge part 222b, and a coupling lever 222c. The cover main body 222a may be formed to block a part of the lower side of the dust bin main body 221. The cover main body 222a may be rotated downward about the hinge part 222b. The hinge part 222b may be disposed adjacent to a battery housing 230. The discharge cover 222 may be coupled to the dust bin 220 by a hook engagement. Meanwhile, the discharge cover 222 may be separated from the dust bin 220 by means of the coupling lever 222c. The coupling lever 222c may be disposed at a front side of the dust bin. Specifically, the coupling lever 241 may be disposed on an outer surface at the front side of the dust bin 220. When external force is applied to the coupling lever 222c, the coupling lever 222c may elastically deform a hook extending from the cover main body 222a in order to release the hook engagement between the cover main body 222a and the dust bin main body 221.
When the discharge cover 222 is closed, the lower side of the dust bin 220 may be blocked (sealed) by the discharge cover 222 and the lower extension portion 221a.
The dust bin 220 may include the dust bin compression lever 223. The dust bin compression lever 223 may be disposed outside the dust bin 220 or the dust separating part 213. The dust bin compression lever 223 may be disposed outside the dust bin 220 or the dust separating part 213 so as to be movable upward and downward. The dust bin compression lever 223 may be connected to the compression member (not illustrated). When the dust bin compression lever 223 is moved downward by external force, the compression member (not illustrated) may also be moved downward. Therefore, it is possible to provide convenience for the user. The compression member (not illustrated) and the dust bin compression lever 223 may return back to original positions by an elastic member (not illustrated). Specifically, when the external force applied to the dust bin compression lever 223 is eliminated, the elastic member may move the dust bin compression lever 223 and the compression member (not illustrated) upward.
The compression member (not illustrated) may be disposed in the dust bin main body 221. The compression member may move in the internal space of the dust bin main body 221. Specifically, the compression member may move upward and downward in the dust bin main body 221. Therefore, the compression member may compress the dust in the dust bin main body 221. In addition, when the discharge cover 222 is separated from the dust bin main body 221 and thus the lower side of the dust bin 220 is opened, the compression member may move from an upper side of the dust bin 220 to the lower side of the of the dust bin 220, thereby removing foreign substances such as residual dust in the dust bin 220. Therefore, it is possible to improve the suction force of the cleaner by preventing the residual dust from remaining in the dust bin 220. Further, it is possible to remove an offensive odor caused by the residual dust by preventing the residual dust from remaining in the dust bin 220.
The first cleaner 200 may include the battery housing 230. A battery 240 may be accommodated in the battery housing 230. The battery housing 230 may be disposed at a lower side of the handle 216. For example, the battery housing 230 may have a hexahedral shape opened at a lower side thereof. A rear surface of the battery housing 230 may be connected to the handle 216.
The battery housing 230 may include an accommodation portion opened at a lower side thereof. The battery 240 may be attached or detached through the accommodation portion of the battery housing 230.
The first cleaner 200 may include the battery 240.
For example, the battery 240 may be separably coupled to the first cleaner 200. The battery 240 may be separably coupled to the battery housing 230. For example, the battery 240 may be inserted into the battery housing 230 from the lower side of the battery housing 230.
Otherwise, the battery 240 may be integrally provided in the battery housing 230. In this case, a lower surface of the battery 240 is not exposed to the outside.
The battery 240 may supply power to the suction motor 214 of the first cleaner 200.
The battery 240 may be disposed on a lower portion of the handle 216. The battery 240 may be disposed at a rear side of the dust bin 220. That is, the suction motor 214 and the battery 240 may be disposed so as not to overlap each other in the upward/downward direction and disposed at different disposition heights. On the basis of the handle 216, the suction motor 214, which is heavy in weight, is disposed at a front side of the handle 216, and the battery 240, which is heavy in weight, is disposed at the lower side of the handle 216, such that an overall weight of the first cleaner 200 may be uniformly distributed. Therefore, it is possible to prevent stress from being applied to the user's wrist when the user grasps the handle 216 and performs a cleaning operation.
In a case in which the battery 240 is coupled to the battery housing 230 in accordance with the embodiment, the lower surface of the battery 240 may be exposed to the outside. Because the battery 240 may be placed on the floor when the first cleaner 200 is placed on the floor, the battery 240 may be immediately separated from the battery housing 230. In addition, because the lower surface of the battery 240 is exposed to the outside and thus in direct contact with air outside the battery 240, performance of cooling the battery 240 may be improved.
Meanwhile, in a case in which the battery 240 is fixed integrally to the battery housing 230, the number of structures for attaching or detaching the battery 240 and the battery housing 230 may be reduced, and as a result, it is possible to reduce an overall size of the first cleaner 200 and a weight of the first cleaner 200.
The first cleaner 200 may include the 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 part 211 of the main body 210. The extension tube 250 may be formed in a long cylindrical shape.
The main body 210 may be connected to the extension tube 250. The main body 210 may be connected to the cleaning module 260 through the extension tube 250. The main body 210 may generate the suction force by means of the suction motor 214 and provide the suction force to the cleaning module 260 through the extension tube 250. The outside dust may be introduced into the main body 210 through the cleaning module 260 and the extension tube 250.

Meanwhile, referring to
The dust in the dust bin 220 of the first cleaner 200 may be captured by a dust collecting part 170 of the cleaner station 100 by gravity and a suction force of a dust collecting motor 191. Therefore, it is possible to remove the dust in the dust bin without the user's separate manipulation, thereby providing convenience for the user. In addition, it is possible to eliminate the inconvenience caused because the user needs to empty the dust bin all the time. In addition, it is possible to prevent the dust from scattering when emptying the dust bin.

The housing 110 may have a space capable of accommodating the dust collecting part 170 configured to store dust therein, and a dust suction module 190 configured to generate a flow force for collecting the dust from the dust collecting part 170.
The housing 110 may include a bottom surface 111 and an outer wall surface 112.
The bottom surface 111 may support a lower side in a gravitational direction of the dust suction module 190. That is, the bottom surface 111 may support a lower side of the dust collecting motor 191 of the dust suction module 190.
In this case, the bottom surface 111 may be disposed toward the ground surface. The bottom surface 111 may also be disposed in parallel with the ground surface or disposed to be inclined at a predetermined angle with respect to the ground surface. The above-mentioned configuration may be advantageous in stably supporting the dust collecting motor 191 and maintaining balance of an overall weight even in a case in which the first cleaner 200 is coupled.
Meanwhile, according to the embodiment, the bottom surface 111 may further include ground surface support portions (not illustrated) in order to prevent the cleaner station 100 from falling down and increase an area being in contact with the ground surface to maintain the balance. For example, the ground surface support portion may have a plate shape extending from the bottom surface 111, and one or more frames may protrude and extend from the bottom surface 111 in a direction of the ground surface. In this case, the ground surface support portions may be disposed to be linearly symmetrical in order to maintain the left and right balance and the front and rear balance on the basis of a front surface on which the first cleaner 200 is mounted.
The outer wall surface 112 may mean a surface formed in the gravitational direction or a surface connected to the bottom surface 111. For example, the outer wall surface 112 may mean 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 disposed to be inclined at a predetermined angle with respect to the bottom surface 111.

In this case, the front side may mean a side at which the first cleaner 200 or the second cleaner 300 is coupled. Therefore, the first outer wall surface 112a may define an external appearance of the front surface of the cleaner station 100.

In this case, a surface including an extension line 212a of the suction part 212 may be referred to as the front surface (see
In another point of view, in a state in which a lever pulling arm 161 is seated on the housing 110, a surface including a side through which the lever pulling arm 161 is exposed to the outside may be referred to as the front surface.
In still another point of view, in the state in which the first cleaner 200 is mounted on the cleaner station 100, an outer surface of the cleaner station 100, which is penetrated by the main body 210 of the first cleaner, may be referred to as the front surface.
Further, in the state in which the first cleaner 200 is mounted on the cleaner station 100, a direction in which the first cleaner 200 is exposed to the outside of the cleaner station 100 may be referred to as a forward direction.

Further, a direction opposite to the direction in which the suction motor 214 is disposed on the cleaner station 100 may be referred to as a rearward direction.
In still another point of view, a direction in which an intersection point at which the handle axis a3 and the motor axis a1 intersect is disposed may be referred to as the forward direction on the basis of the cleaner station 100. Alternatively, a direction in which an intersection point at which the handle axis a3 and the suction flow path centerline a2 intersect is disposed may be referred to as the forward direction. Alternatively, a direction in which an intersection point at which the motor axis a1 and the suction flow path centerline a2 intersect is disposed may be referred to as the forward direction. Further, a direction opposite to the direction in which the intersection point is disposed may be referred to as the rearward direction on the basis of the cleaner station 100.
Further, on the basis of the internal space of the housing 110, a surface facing the front surface may be referred to as a rear surface of the cleaner station 100. That is, a direction, which is opposite to the forward direction based on the dust collecting motor 191, may be referred to as the rearward direction. Therefore, the rear surface may mean a direction in which the second outer wall surface 112b is formed.
Further, on the basis of the internal space of the housing 110, a left surface when viewing the front surface may be referred to as a left surface, and a right surface when viewing the front surface may be referred to as a right surface. Therefore, the left surface may mean a direction in which the third outer wall surface 112c is formed, and the right surface may mean a direction in which the fourth outer wall surface 112d is formed.
The first outer wall surface 112a may be formed in the form of a flat surface, or the first outer wall surface 112a may be formed in the form of a curved surface as a whole or formed to partially include a curved surface.
The first outer wall surface 112a may have an external appearance corresponding to the shape of the first cleaner 200. In detail, the coupling part 120 may be disposed on the first outer wall surface 112a.

For example, the first outer wall surface 112a may have an arm accommodating groove in which the lever pulling arm 161 may be accommodated. In this case, the arm accommodating groove may be formed to correspond to a shape of the lever pulling arm 161. Therefore, when the lever pulling arm 161 is mounted in the arm accommodating groove, the first outer wall surface 112a and an outer surface of the lever pulling arm 161 may define a continuous external shape, and the lever pulling arm 161 may be stroke-moved to protrude from the first outer wall surface 112a by the operation of the lever pulling unit 160.

In the present embodiment, the second outer wall surface 112b may be a surface facing the first outer wall surface 112a. That is, the second outer wall surface 112b may be disposed on the rear surface of the cleaner station 100. In this case, the rear surface may be a surface facing the surface to which the first cleaner 200 or the second cleaner 300 is coupled. Therefore, the second outer wall surface 112b may define an external appearance of the rear surface of the cleaner station 100.
For example, the second outer wall surface 112b may be formed in the form of a flat surface. With this configuration, the cleaner station 100 may be in close contact with a wall in a room, and the cleaner station 100 may be stably supported.
As another example, the structure for mounting various types of cleaning modules 260 used for the first cleaner 200 may be additionally provided on the second outer wall surface 112b.
In addition, the structure to which the second cleaner 300 may be coupled may be additionally provided on the second outer wall surface 112b. Therefore, the structure corresponding to the shape of the second cleaner 300 may be additionally provided on the second outer wall surface 112b.

The coupling part 120 of the cleaner station 100 according to the present disclosure will be described below with reference to
The cleaner station 100 may include the coupling part 120 to which the first cleaner 200 is coupled. Specifically, the coupling part 120 may be disposed in the first outer wall surface 112a, and the main body 210, the dust bin 220, and the battery housing 230 of the first cleaner 200 may be coupled to the coupling part 120.
The coupling part 120 may include the coupling surface 121. The coupling surface 121 may be disposed on the lateral surface of the housing 110. For example, the coupling surface 121 may mean a surface formed in the form of a groove which is concave toward the inside of the cleaner station 100 from the first outer wall surface 112a. That is, the coupling surface 121 may mean a surface formed to have a stepped portion with respect to the first outer wall surface 112a.
The first cleaner 200 may be coupled to the coupling surface 121. For example, the coupling surface 121 may be in contact with the lower surface of the dust bin 220 and the lower surface of the battery housing 230 of the first cleaner 200. In this case, the lower surface may mean a surface directed toward the ground surface when the user uses the first cleaner 200 or places the first cleaner 200 on the ground surface.
In this case, the coupling between the coupling surface 121 and the dust bin 220 of the first cleaner 200 may mean physical coupling by which the first cleaner 200 and the cleaner station 100 are coupled and fixed to each other. This may be a premise of coupling of a flow path through which the dust bin 220 and a flow path part 180 communicate with each other and a fluid may flow.
Further, the coupling between the coupling surface 121 and the battery housing 230 of the first cleaner 200 may mean physical coupling by which the first cleaner 200 and the cleaner station 100 are coupled and fixed to each other. This may be a premise of electrical coupling by which the battery 240 and a charging part 128 are electrically connected to each other.
For example, an angle of the coupling surface 121 with respect to the ground surface may be a right angle. Therefore, it is possible to minimize a space of the cleaner station 100 when the first cleaner 200 is coupled to the coupling surface 121.
As another example, the coupling surface 121 may be disposed to be inclined at a predetermined angle with respect to the ground surface. Therefore, the cleaner station 100 may be stably supported when the first cleaner 200 is coupled to the coupling surface 121.
The coupling surface 121 may have a dust passage hole 121a through which air outside the housing 110 may be introduced into the housing 110. The dust passage hole 121a may be formed in the form of a hole corresponding to the shape of the dust bin 220 so that the dust in the dust bin 220 may be introduced into the dust collecting part 170. The dust passage hole 121a may be formed to correspond to the shape of the discharge cover 222 of the dust bin 220. The dust passage hole 121a may be formed to communicate with a first flow path 181 to be described below.
The coupling part 120 may include the dust bin guide surface 122. The dust bin guide surface 122 may be disposed on the first outer wall surface 112a. The dust bin guide surface 122 may be connected to the first outer wall surface 112a. In addition, the dust bin guide surface 122 may be connected to the coupling surface 121.
The dust bin guide surface 122 may be formed in a shape corresponding to the outer surface of the dust bin 220. A front outer surface of the dust bin 220 may be coupled to the dust bin guide surface 122. Therefore, it is possible to provide convenience when coupling the first cleaner 200 to the coupling surface 121.
The coupling part 120 may include guide protrusions 123. The guide protrusions 123 may be disposed on the coupling surface 121. The guide protrusions 123 may protrude upward from the coupling surface 121. Two guide protrusions 123 may be disposed to be spaced apart from each other. A distance between the two guide protrusions 123, which are spaced apart from each other, may correspond to a width of the battery housing 230 of the first cleaner 200. Therefore, it is possible to provide convenience when coupling the first cleaner 200 to the coupling surface 121.
The coupling part 120 may include sidewalls 124. The sidewalls 124 may mean wall surfaces disposed on two lateral surfaces of the coupling surface 121 and may be perpendicularly connected to the coupling surface 121. The sidewalls 124 may be connected to the first outer wall surface 112a. In addition, the sidewalls 124 may be connected to the dust bin guide surface 122. That is, the sidewalls 124 may define surfaces connected to the dust bin guide surface 122. Therefore, the first cleaner 200 may be stably accommodated.
The coupling part 120 may include the coupling sensor 125. The coupling sensor 125 may detect whether the first cleaner 200 is coupled to the coupling part 120.
The coupling sensor 125 may include a contact sensor. For example, the coupling sensor 125 may include a micro-switch. In this case, the coupling sensor 125 may be disposed on the guide protrusion 123. Therefore, when the battery housing 230 or the battery 240 of the first cleaner 200 is coupled between the pair of guide protrusions 123, the battery housing 230 or the battery 240 comes into contact with the coupling sensor 125, such that the coupling sensor 125 may detect that the first cleaner 200 is physically coupled to the cleaner station 100.
Meanwhile, the coupling sensor 125 may include a non-contact sensor. For example, the coupling sensor 125 may include an infrared ray (IR) sensor. In this case, the coupling sensor 125 may be disposed on the sidewall 124. Therefore, when the dust bin 220 or the main body 210 of the first cleaner 200 passes the sidewall 124 and then reaches the coupling surface 121, the coupling sensor 125 may detect the presence of the dust bin 220 or the main body 210 and detect that the first cleaner 200 is physically coupled to the cleaner station 100.
The coupling sensor 125 may face the dust bin 220 or the battery housing 230 of the first cleaner 200.
The coupling sensor 125 may be a mean for determining whether the first cleaner 200 is coupled and power is applied to the battery 240 of the first cleaner 200.
The coupling part 120 may include the suction part guide surface 126. The suction part guide surface 126 may be disposed on the first outer wall surface 112a. The suction part guide surface 126 may be connected to the dust bin guide surface 122. The suction part 212 may be coupled to the suction part guide surface 126. The suction part guide surface 126 may be formed in a shape corresponding to the shape of the suction part 212. Therefore, it is possible to provide convenience when coupling the main body 210 of the first cleaner 200 to the coupling surface 121.
The coupling part 120 may include fixing member entrance holes 127. The fixing member entrance hole 127 may be formed in the form of a long hole along the sidewall 124 so that a fixing member 131 may enter and exit the fixing member entrance hole 127. For example, the fixing member entrance hole 127 may be a rectangular hole formed along the sidewall 124. The fixing member 131 will be described below in detail.
With this configuration, when the user couples the first cleaner 200 to the coupling part 120 of the cleaner station 100, the main body 210 of the first cleaner 200 may be stably disposed on the coupling part 120 by the dust bin guide surface 122, the guide protrusions 123, and the suction part guide surface 126. Therefore, it is possible to provide convenience when coupling the dust bin 220 and the battery housing 230 of the first cleaner 200 to the coupling surface 121.
Meanwhile,
To avoid the repeated description, the description of the cleaner station according to the embodiment of the present disclosure may be applied, except for the components that have not been particularly described in the present embodiment, because the same configuration and effect of the cleaner station may be applied.
Referring to
Therefore, it is possible to provide convenience when coupling the main body 210 of the first cleaner 200 to the coupling surface 121. That is, it is possible to provide convenience because the first cleaner 200 is coupled to the coupling surface 121 by the weight of the first cleaner 200 when the first cleaner 200 is placed on the coupling surface 121.

The fixing unit 130 may include the fixing members 131 configured to fix the dust bin 220 and the battery housing 230 of the first cleaner 200, and a fixing part motor 133 configured to operate the fixing members 131. In addition, the fixing unit 130 may further include fixing part gears 134 configured to transmit power from the fixing part motor 133 to the fixing members 131, and fixing part links 135 configured to convert rotational motions of the fixing part gears 134 into reciprocating motions of the fixing members 131. Further, the fixing unit 13 may further include a fixing part housing 132 configured to accommodate the fixing part motor 133 and the fixing part gears 134.
The fixing members 131 may be disposed on the sidewall 124 of the coupling part 120 and provided on the sidewall 124 so as to reciprocate in order to fix the dust bin 220. Specifically, the fixing members 131 may be accommodated in the fixing member entrance holes 127.
The fixing members 131 may be disposed at both sides of the coupling part 120, respectively. For example, a pair of two fixing members 131 may be symmetrically disposed with respect to the coupling surface 121.
Specifically, the fixing member 131 may include a link coupling portion 131a, a movable panel 131b, and a movable sealer 131c. In this case, the link coupling portion 131a may be disposed at one side of the movable panel 131b, and the movable sealer 131c may be disposed at the other side of the movable panel 131b.
The link coupling portion 131a is disposed at one side of the movable panel 131b and coupled to the fixing part link 135. For example, the link coupling portion 131a may protrude in a cylindrical shape or a circular pin shape from a connection projection 131bb formed by bending and extending one end of the movable panel 131b. Therefore, the link coupling portion 131a may be rotatably inserted and coupled into one end of the fixing part link 135.
The movable panel 131b may be connected to the link coupling portion 131a and provided to be reciprocally movable from the sidewall 124 toward the dust bin 220 by the operation of the fixing part motor 133. For example, the movable panel 131b may be provided to be rectilinearly and reciprocally movable along a guide frame 131d.
Specifically, one side of the movable panel 131b may be disposed to be accommodated in a space in the first outer wall surface 112a, and the other side of the movable panel 131b may be disposed to be exposed from the sidewall 124.
The movable panel 131b may include a panel main body 131ba, the connection projection 131bb, a first pressing portion 131bc, and a second pressing portion 131bd. For example, the panel main body 131ba may be formed in the form of a flat plate. In addition, the connection projection 131bb may be disposed at one end of the panel main body 131ba. Further, the first pressing portion 131bc may be formed at the other end of the panel main body 131ba.
The connection projection 131bb may be formed by bending and extending one end of the panel main body 131ba toward the fixing part motor 133. The link coupling portion 131a may protrude and extend from the tip of the connection projection 131bb.
The connection projection 131bb may have a frame through hole that may be penetrated by the guide frame 131d. For example, the frame through hole may be formed in a shape similar to an T shape.
The first pressing portion 131bc is formed at the other end of the panel main body 131ba and formed in a shape corresponding to the shape of the dust bin 220 in order to seal the dust bin 220.

That is, the first pressing portion 131bc may mean an end portion having a concave arc shape and formed at the other side of the panel main body 131ba.
The second pressing portion 131bd may be connected to the first pressing portion 131bc and formed in a shape corresponding to the shape of the battery housing 230 in order to seal the battery housing 230.

That is, the second pressing portion 131bd may mean an end portion having a straight shape and formed at the other side of the panel main body 131ba.
The movable sealer 131c may be disposed on a tip in the reciprocation direction of the movable panel 131b and may seal the dust bin 220. Specifically, the movable sealer 131c may be coupled to the first pressing portion 131bc and may seal a space between the dust bin 220 and the first pressing portion 131bc when the first pressing portion 131bc surrounds and presses the dust bin 220.

With this configuration, the movable panel 131b may rectilinearly reciprocate along the guide frame 131d.
The fixing part housing 132 may be disposed in the housing 110. For example, the fixing part housing 132 may be disposed on the back surface to the coupling surface 121.
The fixing part housing 132 may have therein a space capable of accommodating the fixing part gears 134. Further, the fixing part housing 132 may accommodate the fixing part motor 133.
The fixing part housing 132 may include a first fixing part housing 132a, a second fixing part housing 132b, link guide holes 132c, and a motor accommodation portion 132d.
The first fixing part housing 132a and the second fixing part housing 132b are coupled to each other to define the space capable of accommodating the fixing part gears 134 therein.
For example, the first fixing part housing 132a may be disposed in a direction toward the outside of the cleaner station 100, and the second fixing part housing 132b may be disposed in a direction toward the inside of the cleaner station 100. That is, the first fixing part housing 132a may be disposed in a direction toward the coupling surface 121, and the second fixing part housing 132b may be disposed in a direction toward the second outer wall surface 112b.
The link guide holes 132c may be formed in the first fixing part housing 132a. The link guide holes 132c may mean holes formed to guide movement routes of the fixing part link 135. For example, the link guide hole 132c may mean an arc-shaped hole formed in a circumferential direction about a rotary shaft of the fixing part gear 134.
Two link guide holes 132c may be formed to guide the pair of fixing part links 135 for moving the pair of fixing members 131. In addition, the two link guide holes 132c may be symmetrically formed.
The motor accommodation portion 132d may be provided to accommodate the fixing part motor 133. For example, the motor accommodation portion 132d may protrude in a cylindrical shape from the first fixing part housing 132a in order to accommodate the fixing part motor 133 therein.
The fixing part motor 133 may provide power for moving the fixing members 131. Specifically, the fixing part motor 133 may rotate the fixing part gears 134 in a forward direction or a reverse direction. In this case, the forward direction may mean a direction in which the fixing member 131 is moved from the sidewall 124 to press the dust bin 220. In addition, the reverse direction may mean a direction in which the fixing member 131 is moved to the inside of the sidewall 124 from a position at which the fixing member 131 presses the dust bin 220. The forward direction may be opposite to the reverse direction.
The fixing part gears 134 may be coupled to the fixing part motor 133 and may move the fixing members 131 using power from the fixing part motor 133.
The fixing part gears 134 may include a driving gear 134a, a connection gear 134b, a first link rotating gear 134c, and a second link rotating gear 134d.
A shaft of the fixing part motor 133 may be inserted and coupled into the driving gear 134a. For example, the shaft of the fixing part motor 133 may be inserted and fixedly coupled into the driving gear 134a. As another example, the driving gear 134a may be formed integrally with the shaft of the fixing part motor 133.
The connection gear 134b may engage with the driving gear 134a and the first link rotating gear 134c.
The other end of the fixing part link 135 is rotatably coupled to the first link rotating gear 134c, and the first link rotating gear 134c may transmit rotational force transmitted from the driving gear 134a to the fixing part link 135.
The first link rotating gear 134c may include a rotary shaft 134ca, a rotation surface 134cb, gear teeth 134cc, and a link fastening portion 134cd.
The rotary shaft 134ca may be coupled to and supported by the first fixing part housing 132a and the second fixing part housing 132b. The rotation surface 134cb may be formed in a circular plate shape having a predetermined thickness about the rotary shaft 134ca. The gear teeth 134cc may be formed on an outer circumferential surface of the rotation surface 134cb and may engage with the connection gear 134b. Further, the gear teeth 134cc may engage with the second link rotating gear 134d. With this configuration, the first link rotating gear 134c may receive power from the fixing part motor 133 through the driving gear 134a and the connection gear 134b and transmit the power to the second link rotating gear 134d.
The link fastening portion 134cd may protrude and extend in a cylindrical shape or a circular pin shape in an axial direction from the rotation surface 134cb. The link fastening portion 134cd may be rotatably coupled to the other end of the fixing part link 135. For example, the link fastening portion 134cd may penetrate the link guide hole 132c and may be coupled to the other end of the fixing part link 135. With this configuration, the first link rotating gear 134c may be rotated by power from the fixing part motor 133, the fixing part link 135 may be rotated and rectilinearly moved by the rotation of the first link rotating gear 134c, and consequently, the fixing member 131 may be moved to fix or release the dust bin 220.
The second link rotating gear 134d may engage with the first link rotating gear 134c and rotate in a direction opposite to the rotation direction of the first link rotating gear 134c.
The other end of the fixing part link 135 is rotatably coupled to the second link rotating gear 134d, and the second link rotating gear 134d may transmit the rotational force transmitted from the driving gear 134a to the fixing part link 135.
The second link rotating gear 134d may include a rotary shaft 134da, a rotation surface 134db, gear teeth 134dc, and a link fastening portion 134dd.
The rotary shaft 134da may be coupled to and supported by the first fixing part housing 132a and the second fixing part housing 132b. The rotation surface 134db may be formed in a circular plate shape having a predetermined thickness about the rotary shaft 134da. The gear teeth 134dc may be formed on an outer circumferential surface of the rotation surface 134db and may engage with the first link rotating gear 134c. With this configuration, the second link rotating gear 134d may receive the power from the fixing part motor 133 through the driving gear 134a, the connection gear 134b, and the first link rotating gear 134c.
The link fastening portion 134dd may protrude and extend in a cylindrical shape or a circular pin shape in an axial direction from the rotation surface 134db. The link fastening portion 134dd may be rotatably coupled to the other end of the fixing part link 135. For example, the link fastening portion 134dd may penetrate the link guide hole 132c and may be coupled to the other end of the fixing part link 135. With this configuration, the second link rotating gear 134d may be rotated by power from the fixing part motor 133, the fixing part link 135 may be rotated and rectilinearly moved by the rotation of the second link rotating gear 134d, and consequently, the fixing member 131 may be moved to fix or release the dust bin 220.
The fixing part links 135 may link the fixing part gears 134 and the fixing members 131 and convert the rotations of the fixing part gears 134 into the reciprocation movements of the fixing members 131.
One end of the fixing part link 135 may be coupled to the link coupling portion 131a of the fixing member 131, and the other end of the fixing part link 135 may be coupled to the link fastening portion 134cd or 134dd of the fixing part gear 134.
The fixing part link 135 may include a link main body 135a, a first link connecting portion 135b, and a second link connecting portion 135c.
For example, the link main body 135a may be formed in the form of a frame with a bent central portion. This is to improve efficiency in transmitting power by changing an angle at which a force is transmitted.
The first link connecting portion 135b may be disposed at one end of the link main body 135a, and the second link connecting portion 135c may be disposed at the other end of the link main body 135a. The first link connecting portion 135b may be protrude in a cylindrical shape from one end of the link main body 135a. The first link connecting portion 135b may have a hole into which the link coupling portion 131a may be inserted and coupled. The second link connecting portion 135c may protrude in a cylindrical shape from the other end of the link main body 135a. In this case, a height by which the second link connecting portion 135c protrudes may be greater than a height by which the first link connecting portion 135b protrudes. This is to enable the link fastening portions 134cd and 134dd of the fixing part gears 134 to be accommodated in the link guide holes 132c and move along the link guide holes 132c, and to support the link fastening portions 134cd and 134dd when the link fastening portions 134cd and 134dd rotate. The second link connecting portion 135c may have a hole into which the link fastening portion 134cd or 134dd may be inserted and coupled.
A stationary sealer 136 may be disposed on the dust bin guide surface 122 so as to seal the dustbin 220 when the cleaner 200 is coupled. With this configuration, when the dust bin 220 of the cleaner 200 is coupled, the cleaner 200 may press the stationary sealer 136 by its own weight, such that the dust bin 220 and the dust bin guide surface 122 may be sealed.
The stationary sealer 136 may be disposed in an imaginary extension line of the movable sealer 131c. With this configuration, when the fixing part motor 133 operates and the fixing members 131 press the dust bin 220, a circumference of the dust bin 220 at the same height may be sealed. That is, the stationary sealer 136 and the movable sealers 131c may seal outer circumferential surfaces of the dust bin 220 disposed on concentric circles.
According to the embodiment, the stationary sealer 136 may be disposed on the dust bin guide surface 122 and formed in the form of a bent line corresponding to an arrangement of a cover opening unit 150 to be described below.
Therefore, when the main body 210 of the first cleaner 200 is disposed on the coupling part 120, the fixing unit 130 may fix the main body 210 of the first cleaner 200. Specifically, when the coupling sensor 125 detects that the main body 210 of the first cleaner 200 is coupled to the coupling part 120 of the cleaner station 100, the fixing part motor 133 may move the fixing members 131 to fix the main body 210 of the first cleaner 200.
The fixing unit 130 may further include fixing detecting parts 137. The fixing detecting parts 137 may be provided in the housing 110 and may detect whether the fixing members 131 fix the first cleaner 200.
For example, the fixing detecting parts 137 may be disposed at both ends in a rotational region of the fixing part links 135, respectively.
Therefore, when the fixing members 131 are moved to a predetermined fixing position FP1, the fixing detecting parts 137 may detect that first cleaner 200 is fixed. In addition, when the fixing members 131 are moved to a predetermined releasing position FP2, the fixing detecting parts 137 may detect that the first cleaner 200 is released.
The fixing detecting part 137 may include a contact sensor. For example, the fixing detecting part 137 may include a micro-switch.
Meanwhile, the fixing detecting part 137 may include a non-contact sensor. For example, the fixing detecting part 137 may include an infrared (IR) sensor.
With this configuration, the first cleaner 200 may automatically detect the coupled state of the first cleaner 200 and fix the dust bin 220 of the first cleaner at the time of coupling the first cleaner 200 to the cleaner station 100, which makes it possible to allow the user to seal the first cleaner 200 without applying a separate force.
In addition, the first cleaner 200 may automatically detect the coupled state of the first cleaner 200 and seal the first cleaner 200 at the time of coupling the first cleaner 200 to the cleaner station 100, which makes it possible to improve the efficiency in preventing dust from scattering.
Meanwhile,
Another embodiment of a fixing unit 1130 according to the present disclosure will be described below with reference to
To avoid the repeated description, the description of the fixing unit 130 according to the embodiment of the present disclosure may be applied, except for the components that have not been particularly described in the present embodiment, because the same structure and effect of the fixing unit 130 may be applied.
In the present embodiment, the fixing member 1131 may include a rotary sealer 1131a, a coupling part 1131b, and a sealing member 1131c.
The rotary sealer 1131a may be formed to correspond to the shape of the dust bin 220 and the shape of the battery housing 230. Specifically, the rotary sealer 1131a may be shaped to surround the outer surface of the dust bin 220. For example, the rotary sealer 1131a may include an arc-shaped portion having a radius corresponding to an outer diameter of the dust bin 220. In addition, the rotary sealer 1131a may include a straight portion corresponding to the shape of the battery housing 230.
The coupling part 1131b may be rotatably coupled to the coupling part 120. Specifically, the coupling part 1131b may protrude from a surface of the rotary sealer 1131a that faces a sidewall 1124. A part of the coupling part 1131b may be accommodated in a fixing member entrance hole 1127. The coupling part 1131b may have a hole that may be penetrated by a sealer rotation shaft (not illustrated) that serves as a rotation axis of the rotary sealer 1131a. The sealer rotation shaft (not illustrated) may be provided in the housing 110.
The position of the coupling part 1131b may be disposed downward in the gravitational direction from an intermediate point of the rotary sealer 1131a. This configuration may minimize the resistance of the rotary sealer 1131a at the time of coupling the first cleaner 200 and maximizing the force by which the rotary sealer 1131a surrounds the first cleaner 200.
The rotary sealer 1131a may be configured to surround the second cleaner 200 when the first cleaner 200 is coupled to the coupling part 120. Specifically, when the first cleaner 200 is coupled to the coupling part 120, a front-outer surface of the dust bin 220 of the first cleaner 200 is coupled to the first guide unit 1122, such that the front-outer surface of the dust bin 220 may press the lower end in the gravitational direction of the rotary sealer 1131a. In this case, the rotary sealer 1131a may rotate about the coupling part 1131b while being pressed by the first cleaner 200. As a result, an upper end in the gravitational direction of the rotary sealer 1131a may surround the battery housing 230 and a rear-outer surface of the dust bin 220 of the first cleaner 200 while rotating. That is, the rotary sealer 1131a may fix the first cleaner 200 while being moved by the weight of the first cleaner 200 or by the force by which the first cleaner 200 is coupled.
Meanwhile,
A door unit 140 according to the present disclosure will be described below with reference to
The cleaner station 100 according to the present disclosure may include the door unit 140. The door unit 140 may be configured to open or close the dust passage hole 121a.
The door unit 140 may include a door 141, a door motor 142, and a door arm 143.
The door 141 may be hingedly coupled to the coupling surface 121 and may open or close the dust passage hole 121a. The door 141 may include a door main body 141a, a hinge part 141b, and an arm coupling part 141c.
The door main body 141a may be formed in a shape capable of blocking the dust passage hole 121a. For example, the door main body 141a may be formed in a shape similar to a circular plate shape. On the basis of a state in which the door main body 141a blocks the dust passage hole 121a, the hinge part 141b may be disposed at an upper side of the door main body 141a, and the arm coupling part 141c may be disposed at a lower side of the door main body 141a.
The door main body 141a may be formed in a shape capable of sealing the dust passage hole 121a. For example, an outer surface of the door main body 141a, which is exposed to the outside of the cleaner station 100, is formed to have a diameter corresponding to a diameter of the dust passage hole 121a, and an inner surface of the door main body 141a, which is disposed in the cleaner station 100, is formed to have a diameter greater than the diameter of the dust passage hole 121a. In addition, a level difference may be defined between the outer surface and the inner surface. Meanwhile, one or more reinforcing ribs may protrude from the inner surface in order to connect the hinge part 141b and the arm coupling part 141c and reinforce a supporting force of the door main body 141a.
The hinge part 141b may be a means by which the door 141 is hingedly coupled to the coupling surface 121. The hinge part 141b may be disposed at an upper end of the door main body 141a and coupled to the coupling surface 121.
The arm coupling part 141c may be a means to which the door arm 143 is rotatably coupled. The arm coupling part 141c may be disposed at a lower side of the inner surface, and the door arm 143 may be rotatably coupled to the arm coupling part 141c.
With this configuration, when the door arm 143 pulls the door main body 141a in the state in which the door 141 closes the dust passage hole 121a, the door main body 141a is rotated about the hinge part 141b toward the inside of the cleaner station 100, such that the dust passage hole 121a may be opened. Meanwhile, when the door arm 143 pushes the door main body 141a in the state in which the dust passage hole 121a is opened, the door main body 141a is rotated about the hinge part 141b toward the outside of the cleaner station 100, such that the dust passage hole 121a may be closed.
The door motor 142 may provide power for rotating the door 141. Specifically, the door motor 142 may rotate the door arm 143 in a forward direction or a reverse direction. In this case, the forward direction may mean a direction in which the door arm 143 pulls the door 141. Therefore, when the door arm 143 is rotated in the forward direction, the dust passage hole 121a may be opened. In addition, the reverse direction may mean a direction in which the door arm 143 pushes the door 141. Therefore, when the door arm 143 is rotated in the reverse direction, at least a part of the dust passage hole 121a may be closed. The forward direction may be opposite to the reverse direction.
The door arm 143 may connect the door 141 and the door motor 142 and open or close the door 141 using the power generated from the door motor 142.
For example, the door arm 143 may include a first door arm 143a and a second door arm 143b. One end of the first door arm 143a may be coupled to the door motor 142. The first door arm 143a may be rotated by the power of the door motor 142. The other end of the first door arm 143a may be rotatably coupled to the second door arm 143b. The first door arm 143a may transmit a force transmitted from the door motor 142 to the second door arm 143b. One end of the second door arm 143b may be coupled to the first door arm 143a. The other end of the second door arm 143b may be coupled to the door 141. The second door arm 143b may open or close the dust passage hole 121a by pushing or pulling the door 141.
The door unit 140 may further include door opening/closing detecting parts 144. The door opening/closing detecting parts 144 may be provided in the housing 110 and may detect whether the door 141 is in an opened state.
For example, the door opening/closing detecting parts 144 may be disposed at both ends in a rotational region of the door arm 143, respectively. As another example, the door opening/closing detecting parts 144 may be disposed at both ends in a movement region of the door 141, respectively.
Therefore, when the door arm 143 is moved to a predetermined opened position DP1 or when the door 141 is opened to a predetermined position, the door opening/closing detecting parts 144 may detect that the door is opened. In addition, when the door arm 143 is moved to a predetermined closed position DP2 or when the door 141 is opened to a predetermined position, the door opening/closing detecting parts 144 may detect that the door is opened.
The door opening/closing detecting part 144 may include a contact sensor. For example, the door opening/closing detecting part 144 may include a micro-switch.
Meanwhile, the door opening/closing detecting part 144 may also include a non-contact sensor. For example, the door opening/closing detecting part 144 may include an infrared ray (IR) sensor.
With this configuration, the door unit 140 may selectively open or close at least a part of the coupling surface 121, thereby allowing the outside of the first outer wall surface 112a to communicate with the first flow path 181 and/or the dust collecting part 170.
The door unit 140 may be opened when the discharge cover 222 of the first cleaner 200 is opened. In addition, when the door unit 140 is closed, the discharge cover 222 of the first cleaner 200 may also be closed.
When the dust in the dust bin 220 of the first cleaner 200 is removed, the door motor 142 may rotate the door 141, thereby coupling the discharge cover 222 to the dust bin main body 221. Specifically, the door motor 142 may rotate the door 141 to rotate the door 141 about the hinge part 141b, and the door 141 rotated about the hinge part 141b may push the discharge cover 222 toward the dust bin main body 221.
The cover opening unit 150 according to the present disclosure will be described below with reference to
The cleaner station 100 according to the present disclosure may include the cover opening unit 150. The cover opening unit 150 may be disposed on the coupling part 120 and may open the discharge cover 222 of the first cleaner 200.
The cover opening unit 150 may include a push protrusion 151, a cover opening motor 152, cover opening gears 153, a support plate 154, and a gear box 155.
The push protrusion 151 may move to press the coupling lever 222c when the first cleaner 200 is coupled.
The push protrusion 151 may be disposed on the dust bin guide surface 122. Specifically, a protrusion moving hole may be formed in the dust bin guide surface 122, and the push protrusion 151 may be exposed to the outside by passing through the protrusion moving hole.
When the first cleaner 200 is coupled, the push protrusion 151 may be disposed at a position at which the push protrusion 151 may push the coupling lever 222c. That is, the coupling lever 222c may be disposed on the protrusion moving hole. In addition, the coupling lever 222c may be disposed in a movement region of the push protrusion 151.
The push protrusion 151 may rectilinearly reciprocate to press the coupling lever 222c. Specifically, the push protrusion 151 may be coupled to the gear box 155, such that the rectilinear movement of the push protrusion 151 may be guided. The push protrusion 151 may be coupled to the cover opening gears 153 and moved together with the cover opening gears 153 by the movements of the cover opening gears 153.
For example, the push protrusion 151 may include a protrusion portion 151a, a protrusion support plate 151b, a connection portion 151c, a gear coupling block 151d, and guide frames 151e.
The protrusion portion 151a may be provided to push the coupling lever 222c. The protrusion portion 151a may be formed in a shape similar to a hook shape, a right-angled triangular shape, or a trapezoidal shape. The protrusion support plate 151b may be connected to the protrusion portion 151a and formed in the form of a flat plate for supporting the protrusion portion 151a.
The protrusion support plate 151b may be provided to be movable along an upper surface of the gear box 155. The connection portion 151c may connect the protrusion support plate 151b and the gear coupling block 151d. The connection portion 151c may be formed to have a narrower width than the protrusion support plate 151b and the gear coupling block 151d.
The connection portion 151c may be disposed to penetrate a protrusion through hole 155b formed in the gearbox 155. The gear coupling block 151d may be coupled to the cover opening gears 153. The gear coupling block 151d may be fixedly coupled to the cover opening gears 153 using a member such as a screw or a piece.
The gear coupling block 151d may be accommodated in the gear box 155 and may be rectilinearly reciprocated in the gear box 155 by the movement of the cover opening gears 153. The guide frames 151e may protrude and extend from two lateral surfaces of the gear coupling block 151d, respectively. The guide frames 151e may be protrude and extend in a quadrangular column shape from the gear coupling block 151d.
The guide frame 151e may be disposed to penetrate a guide hole 155c formed in the gear box 155. Therefore, when the gear coupling block 151d rectilinearly moves, the guide frame 151e may rectilinearly reciprocate along the guide hole 155c.
The cover opening motor 152 may provide power for moving the push protrusion 151. Specifically, the cover opening motor 152 may rotate a motor shaft 152a in a forward direction or a reverse direction. In this case, the forward direction may mean a direction in which the push protrusion 151 pushes the coupling lever 222c. In addition, the reverse direction may mean a direction in which the push protrusion 151, which has pushed the coupling lever 222c, returns back to an original position. The forward direction may be opposite to the reverse direction.
The cover opening motor 152 may be disposed outside the gear box 155. The motor shaft 152a of the cover opening motor 152 may penetrate a motor through hole 155e of the gear box 155 and may be coupled to the cover opening gears 153. For example, the motor shaft 152a may be coupled to an opening driving gear 153a and rotated together with the opening driving gear 153a.
The cover opening gears 153 may be coupled to the cover opening motor 152 and may move the push protrusion 151 using the power from the cover opening motor 152. Specifically, the cover opening gears 153 may be accommodated in the gear box 155. The cover opening gears 153 may be coupled to the cover opening motor 152 and supplied with the power. The cover opening gears 153 may be coupled to the push protrusion 151 to move the push protrusion 151.
The cover opening gears 153 may include the opening driving gear 153a and an opening driven gear 153b. Specifically, the shaft 152a of the cover opening motor 152 is inserted and coupled into the opening driving gear 153a, such that the opening driving gear 153a may receive rotational power from the cover opening motor 152.
The opening driven gear 153b may engage with the opening driving gear 153a and may be coupled to the gear coupling block 151d of the push protrusion 151, thereby moving the push protrusion 151. For example, the opening driven gear 153b may be formed in the form of a rack gear so as to engage with the opening driving gear 153a formed in the form of a pinion gear. The opening driven gear 153b may include a body portion 153ba coupled to the gear coupling block 151d. In addition, the opening driven gear 153b may include a gear portion 153bb formed at a lower side of the body portion 153ba and configured to engage with the opening driving gear 153a. Further, the opening driven gear 153b may include guide shafts 153bc protruding from the two lateral surfaces of the body portion 153ba. In addition, the opening driven gear 153b may include gear wheels 153bd into which the guide shafts 153bc are inserted and coupled, and the gear wheels 153bd may rollably move along guide rails 155d formed in an inner surface of the gear box 155.
The support plate 154 may be provided to support one surface of the dust bin 220. Specifically, the support plate 154 may extend from the coupling surface 121. The support plate 154 may protrude and extend toward a center of the dust passage hole 121a from the coupling surface 121.
The support plate 154 may protrude and extend symmetrically from the coupling surface 121, but the present disclosure is not limited thereto, and the support plate 154 may have various shapes capable of supporting the lower extension portion 221a of the first cleaner 200 or the lower surface of the dust bin 220.
When the first cleaner 200 is coupled to the cleaner station 100, the lower surface of the dust bin 220 may be disposed in the dust passage hole 121a, and the support plate 154 may support the lower surface of the dust bin 220. The discharge cover 222 may be openably and closably provided at the lower side of the dust bin 220, and the dust bin 220 may include the cylindrical dust bin main body 221 and the extending lower extension portion 221a. In this case, the support plate 154 may be in contact with the lower extension portion 221a and may support the lower extension portion 221a.
With this configuration, the push protrusion 151 may push the coupling lever 222c of the discharge cover 222 in the state in which the support plate 154 supports the lower extension portion 221a. Therefore, the discharge cover 222 may be opened, and the dust passage hole 121a and the inside of the dust bin 220 may communicate with each other. That is, as the discharge cover 222 is opened, the flow path part 180 and the inside of the dust bin 220 may communicate with each other, and the cleaner station 100 and the first cleaner 200 may be coupled to each other to enable a flow of a fluid (coupling of the flow path).
The gear box 155 may be coupled to the inner surface of the housing 110 and disposed at the lower side of the coupling part 120 in the gravitational direction, and the cover opening gears 153 may be accommodated in the gear box 155. Specifically, the box main body 155a has a space capable of accommodating the cover opening gears 153, and the protrusion through hole 155b, which is penetrated by the connection portion 151c of the push protrusion 151, is formed in an upper surface of the box main body 155a. In addition, the guide hole 155c is formed in the form of a long hole in the lateral surface in a leftward/rightward direction of the box main body 155a, such that the guide frame 151e of the push protrusion 151 penetrates the guide hole 155c.
Meanwhile, the guide rails 155d may be formed on the inner surfaces at the lateral sides in the leftward/rightward direction of the box main body 155a. The guide rails 155d may support the opening driven gear 153b and guide the movement of the opening driven gear 153b.
The motor through hole 155e may be formed in one surface of the gear box 155, and the shaft 152a of the cover opening motor 152 may penetrate the motor through hole 155e. In addition, cover opening detecting parts 155f may be disposed on the lateral surface of the gear box 155.
The cover opening detecting part 155f may include a contact sensor. For example, the cover opening detecting part 155f may include a micro-switch. Meanwhile, the cover opening detecting part 155f may also include a non-contact sensor. For example, the cover opening detecting part 155f may include an infrared (IR) sensor. Therefore, the cover opening detecting part 155f may detect a position of the guide frame 151e, thereby detecting a position of the push protrusion 151.
The cover opening detecting parts 155f may be disposed at both ends of the guide hole 155c formed in the form of a long hole, respectively. Therefore, when the push protrusion 151 is moved to a position at which the push protrusion 151 may push the coupling lever 222c to open the discharge cover 222, the guide frame 151e may be positioned at a predetermined cover opened point CP1, and the cover opening detecting part 155f may detect that the discharge cover 222 is opened. In addition, when the push protrusion 151 returns back to an original position, the guide frame 151e may be positioned at a predetermined cover non-opened point CP2, and the cover opening detecting part 155f may detect that the push protrusion 151 has returned back to the original position.
Accordingly, according to the present disclosure, the cover opening unit 150 may open the dust bin 220 even though the user separately opens the discharge cover 222 of the first cleaner, and as a result, it is possible to improve convenience.
In addition, since the discharge cover 222 is opened in the state in which the first cleaner 200 is coupled to the cleaner station 100, it is possible to prevent the dust from scattering.
Meanwhile,
The lever pulling unit 160 according to the present disclosure will be described below with reference to
The cleaner station 100 according to the present disclosure may include the lever pulling unit 160. The lever pulling unit 160 may be disposed on the first outer wall surface 112a of the housing 110. The lever pulling unit 160 may push the dust bin compression lever 223 of the first cleaner 200 to compress the dust in the dust bin 220.
The lever pulling unit 160 may include a lever pulling arm 161, an arm gear 162, a stroke drive motor 163, a rotation drive motor 164, and arm movement detecting parts 165.
The lever pulling arm 161 is accommodated in the housing 110 and may be provided to be stroke-movable and rotatable. For example, the lever pulling arm 161 may be accommodated in an arm accommodating groove formed in the first outer wall surface 112a. In this case, when an imaginary cylindrical shape is defined with respect to a lower end of the arm accommodating groove, the dust bin compression lever 223 may be disposed in the imaginary cylindrical shape.
The lever pulling arm 161 may be provided to push the dust bin compression lever 223. The lever pulling arm 161 may be formed to correspond to a shape of the arm accommodating groove. For example, the lever pulling arm 161 may be formed in a shape similar to an elongated bar.
One surface of the lever pulling arm 161 may be formed to define a continuous surface together with the first outer wall surface 112a in the state in which the lever pulling arm 161 is accommodated in the arm accommodating groove. The arm gear 162 may be coupled to one side of the other surface of the lever pulling arm 161.
The arm gear 162 may be coupled to the lever pulling arm 161, the stroke drive motor 163, and the rotation drive motor 164. For example, the arm gear 162 may be formed to be similar to a kind of shaft. One end of the shaft of the arm gear 162 may be fixedly coupled to the lever pulling arm 161. The other end of the shaft of the arm gear 162 may be provided in the form of a worm wheel. Therefore, the other end of the shaft of the arm gear 162 is formed in the form of a worm gear and may engage with the rotation drive motor 164. The shaft of the arm gear 162 may be formed in the form of a cylindrical worm. The shaft of the arm gear 162 may be formed in the form of a worm gear and may engage with the stroke drive motor 163.
The stroke drive motor 163 may provide power for stroke-moving the lever pulling arm 161. The stroke drive motor 163 may rotate in a forward direction or a reverse direction. In this case, the forward direction may mean a direction in which the lever pulling arm 161 is moved away from the housing 110 of the cleaner station 100. In addition, the reverse direction may mean a direction in which the lever pulling arm 161 is pulled toward the cleaner station 100. The forward direction may be opposite to the reverse direction.
The rotation drive motor 164 may provide power for rotating the lever pulling arm 161. The rotation drive motor 164 may rotate in a forward direction or a reverse direction. In this case, the forward direction may mean a direction in which the lever pulling arm 161 rotates to a position at which the lever pulling arm 161 may push the dust bin compression lever 223. In addition, the reverse direction may be a direction opposite to the forward direction.
The arm movement detecting parts 165 may be disposed in the housing 110. The arm movement detecting parts 165 may be disposed on a movement route of the shaft of the arm gear 162. The arm movement detecting parts 165 may be disposed at an initial position LP1 of the shaft of the arm gear 162, a maximum stroke movement position LP2, and a position LP3 when the compression lever 223 is pulled, respectively.
The arm movement detecting part 165 may include a contact sensor. For example, the arm movement detecting part 165 may include a micro-switch. Meanwhile, the arm movement detecting part 165 may also include a non-contact sensor. For example, the arm movement detecting part 165 may include an infrared (IR) sensor. With this configuration, the arm movement detecting parts 165 may detect a stroke position of the arm gear 162.
In addition, the arm movement detecting parts 165 may be disposed at the other end of the shaft of the arm gear 162. The arm movement detecting parts 165 may be disposed at the other end of the arm gear 162 provided in the form of a worm wheel and may detect a rotation position. The arm movement detecting part 165 may include a contact sensor. For example, the arm movement detecting part 165 may include a micro-switch. Meanwhile, the arm movement detecting part 165 may also include a non-contact sensor. For example, the arm movement detecting part 165 may include an infrared (IR) sensor or a Hall sensor.
Therefore, the arm movement detecting part 165 may detect that the lever pulling arm 161 is positioned at the initial position. In addition, the arm movement detecting part 165 may detect that the lever pulling arm 161 has been moved maximally away from the housing 110. In addition, the arm movement detecting part 165 may detect that the lever pulling arm 161 rotates to pull the compression lever 223. In addition, the arm movement detecting part 165 may detect that the lever pulling arm 161 has pulled the compression lever 223. In addition, the arm movement detecting part 165 may detect that the lever pulling arm 161 rotates to the original position after pulling the compression lever 223.
Therefore, when the first cleaner 200 is coupled to the coupling part 120, the compression member 224 may move downward as the lever pulling arm 161 stroke-moves, thereby compressing the dust in the dust bin 220. In one embodiment of the present specification, the dust in the dust bin 220 may be captured primarily into the dust collecting part 170 by gravity as the discharge cover 222 is separated from the dust bin 220, and then the residual dust in the dust bin 220 may be captured secondarily into the dust collecting part 170 by the compression member (not illustrated). Otherwise, the compression member (not illustrated) may compress the dust in the dust bin 220 downward in the state in which the discharge cover 222 is coupled to the dust bin 220, and then the discharge cover 222 may be separated from the dust bin 220, such that the dust in the dust bin 220 may be captured into the dust collecting part 170.
Meanwhile, the dust collecting part 170 will be described below with reference to
The cleaner station 100 may include the dust collecting part 170. The dust collecting part 170 may be disposed in the housing 110. The dust collecting part 170 may be disposed at a lower side in the gravitational direction of the coupling part 120.
The dust collecting part 170 may include a roll vinyl film (not illustrated). The roll vinyl film may be fixed to the housing 110 and spread downward by a load of the dust falling from the dust bin 220.
The cleaner station 100 may include a joint part (not illustrated). The joint part may be disposed in the housing 110. The joint part may be disposed in an upper region of the dust collecting part 170. The joint part may cut and join an upper region of the roll vinyl film in which the dust is captured. Specifically, the joint part may retract the roll vinyl film to a central region and join the upper region of the roll vinyl film using a heating wire. The joint part may include a first joint member (not illustrated) and a second joint member (not illustrated). The first joint member (not illustrated) may be moved in a first direction by a first joint drive part 174, and the second joint member (not illustrated) may be moved in a second direction perpendicular to the first direction by a second joint drive part 175.
With this configuration, the dust captured from the first cleaner 200 or the second cleaner 200 may be collected in the roll vinyl film, and the roll vinyl film may be automatically joined. Therefore, it is not necessary for the user to separately bind a bag in which the dust is captured, and as a result, it is possible to improve convenience for the user.
Meanwhile, the flow path part 180 will be described below with reference to
The cleaner station 100 may include the flow path part 180. The flow path part 180 may connect the first cleaner 200 or the second cleaner 300 to the dust collecting part 170.
The flow path part 180 may include the first flow path 181, a second flow path 182, and a flow path switching valve 183.
The first flow path 181 may connect the dust bin 220 of the first cleaner 200 to the dust collecting part 170. The first flow path 181 may be disposed at a rear side of the coupling surface 121. The first flow path 181 may mean a space between the dust bin 220 of the first cleaner 200 and the dust collecting part 170. The first flow path 181 may be a space formed at a rear side of the dust passage hole 121a. The first flow path 181 may be a flow path bent downward from the dust passage hole 121a, and the dust and the air may flow through the first flow path 181. The dust in the dust bin 220 of the first cleaner 200 may move to the dust collecting part 170 through the first flow path 181.
The second flow path 182 may connect the second cleaner 300 to the dust collecting part 170. The dust in the second cleaner 300 may move to the dust collecting part 170 through the second flow path 182.
The flow path switching valve 183 may be disposed between the dust collecting part 170, the first flow path 181, and the second flow path 182. The flow path switching valve 183 may selectively open or close the first flow path 181 and the second flow path 182 connected to the dust collecting part 170. Therefore, it is possible to prevent a decrease in suction force caused when the plurality of flow paths 181 and 182 is opened.
For example, in a case in which only the first cleaner 200 is coupled to the cleaner station 100, the flow path switching valve 183 may connect the first flow path 181 to the dust collecting part 170 and disconnect the second flow path 182 from the dust collecting part 170.
As another example, in a case in which only the second cleaner 300 is coupled to the cleaner station 100, the flow path switching valve 183 may disconnect the first flow path 181 from the dust collecting part 170 and connect the second flow path 182 to the dust collecting part 170.
As still another example, in a case in which both the first cleaner 200 and the second cleaner 300 are coupled to the cleaner station 100, the flow path switching valve 183 may connect the first flow path 181 to the dust collecting part 170 and disconnect the second flow path 182 from the dust collecting part 170 to remove the dust in the dust bin 220 of the first cleaner 200 first. Thereafter, the flow path switching valve 183 may disconnect the first flow path 181 from the dust collecting part 170 and connect the second flow path 182 to the dust collecting part 170 to remove the dust from the second cleaner 300. Therefore, it is possible to improve convenience in respect to the use of the first cleaner 200 manually manipulated by the user.
Meanwhile, the dust suction module 190 will be described below with reference to
The cleaner station 100 may include the dust suction module 190. The dust suction module 190 may include the dust collecting motor 191, a first filter 192, and a second filter (not illustrated).
The dust collecting motor 191 may be disposed below the dust collecting part 170. The dust collecting motor 191 may generate the suction force in the first flow path 181 and the second flow path 182. Therefore, the dust collecting motor 191 may provide the suction force capable of sucking the dust in the dust bin 220 of the first cleaner 200 and the dust in the second cleaner 300.
The dust collecting motor 191 may generate the suction force by means of the rotation. For example, the dust collecting motor 191 may be formed in a shape similar to a cylindrical shape.
The first filter 192 may be disposed between the dust collecting part 170 and the dust collecting motor 191. The first filter 192 may be a prefilter.
The second filter 193 may be disposed between the dust collecting motor 191 and the outer wall surface 112. The second filter 193 may be an HEPA filter.
Meanwhile, in the present embodiment, an imaginary balance maintaining space R1 may perpendicularly extend from the ground surface and penetrate the dust collecting part 170 and the dust suction module 190. For example, the balance maintaining space R1 may be an imaginary space perpendicularly extending from the ground surface, and the dust collecting motor 191 at least may be accommodated in the balance maintaining space R1. That is, the balance maintaining space R1 may be an imaginary cylindrical shape space that accommodates the dust collecting motor 191 therein.
In this case, in the present disclosure, the imaginary extension surface of the gravity center plane S1 penetrates the balance maintaining space R1. With this configuration, the cleaner station 100 may stably maintain the balance in the state in which the first cleaner 200 is mounted on the cleaner station 100 according to the present disclosure.
Meanwhile, the arrangement of the first cleaner 200, the first flow path 181, the dust collecting part 170, and the dust suction module 190 in the state in which the first cleaner 200 is coupled to the cleaner station 100 will be described below with reference to
When the first cleaner 200 is mounted on the cleaner station 100, the axis of the dust bin 220 having a cylindrical shape may be disposed in parallel with the ground surface. Further, the dust bin 220 may be disposed to be perpendicular to the first outer wall surface 112a and the coupling surface 121. That is, the dust bin axis a5 may be disposed to be perpendicular to the first outer wall surface 112a and the coupling surface 121 and disposed in parallel with the ground surface. In addition, the dust bin axis a5 may be disposed to be perpendicular to the axis of the balance maintaining space R1.
Further, when the first cleaner 200 is mounted on the cleaner station 100, the extension tube 250 may be disposed in the direction perpendicular to the ground surface. Further, the extension tube 250 may be disposed in parallel with the first outer wall surface 112a. That is, the suction flow path centerline a2 may be disposed in parallel with the first outer wall surface 112a and disposed to be perpendicular to the ground surface. In addition, the suction flow path centerline a2 may be disposed in parallel with the axis of the balance maintaining space R1.
Meanwhile, when the first cleaner 200 is mounted on the cleaner station 100, at least a part of the outer circumferential surface of the dust bin 220 may be surrounded by the dust bin guide surface 122. The first flow path 181 may be disposed at the rear side of the dust bin 220 and communicate with the first flow path 181 when the dust bin 220 is opened. Further, the first flow path 181 may be bent downward from the dust bin 220. In addition, the dust collecting part 170 may be disposed at the lower side of the first flow path 181. Further, the dust suction module 190 may be disposed at the lower side of the dust collecting part 170.
Therefore, according to the present disclosure, the first cleaner 200 may be mounted on the cleaner station 100 in the state in which the extension tube 250 and the cleaning module 260 are mounted. Further, it is possible to minimize an occupied space on the horizontal plane even in the state in which the first cleaner 200 is mounted on the cleaner station 100.
In addition, according to the present disclosure, since the first flow path 181, which communicates with the dust bin 220, is bent downward only once, it is possible to minimize a loss of flow force for collecting the dust.
Further, according to the present disclosure, in the state in which the first cleaner 200 is mounted on the cleaner station 100, the outer circumferential surface of the dust bin 220 is surrounded by the dust bin guide surface 122, and the dust bin 220 is accommodated in the coupling part 120. As a result, the dust in the dust bin is invisible from the outside.
The cleaner station 100 may include the charging part 128. The charging part 128 may be disposed on the coupling part 120. Specifically, the charging part 128 may be disposed on the coupling surface 121. In this case, the charging part 128 may be positioned at a position facing a charging terminal provided on the battery 240 of the first cleaner 200. The charging part 128 may be electrically connected to the first cleaner 200 coupled to the coupling part 120. The charging part 128 may supply power to the battery 240 of the first cleaner 200 coupled to the coupling part 120. That is, when the first cleaner 200 is physically coupled to the coupling surface 121, the charging part 128 may be electrically coupled to the first cleaner 200.
In addition, the charging part 128 may include a lower charging part (not illustrated) disposed in a lower region of the housing 110. The lower charging part may be electrically connected to the second cleaner 300 coupled to the lower region of the housing 110. A second charger may supply power to the battery of the second cleaner 300 coupled to the lower region of the housing 110.
The cleaner station 100 may include a lateral door (not illustrated). The lateral door may be disposed in the housing 110. The lateral door may selectively expose the dust collecting part 170 to the outside. Therefore, the user may easily remove the dust collecting part 170 from the cleaner station 100.
Meanwhile,
The control configuration according to the present disclosure will be described below with reference to

As a result, the dust passage hole 121a may communicate with the inside of the dust bin 220. Therefore, the cleaner station 100 and the second cleaner 200 may be coupled to each other to enable a flow of a fluid (coupling of the flow path).
When the guide frame 151e reaches the predetermined opened position CP1, the cover opening detecting part 155f may transmit a signal indicating that the discharge cover 222 is opened.
