Description

Dust collector base station and control method thereof

Technical Field

The present invention relates to a vacuum cleaner base station and a control method of the vacuum cleaner base station, and more particularly, to a vacuum cleaner base station and a control method of the vacuum cleaner base station capable of separating dust contained in air and collecting the dust in a dust bag, and capable of emptying only the dust bag.

Background

In general, a vacuum cleaner is an electric home appliance that sucks small garbage or dust in a manner of sucking air by using electricity and fills it in a dust tub located in a product, and is generally called a vacuum cleaner.

Such a cleaner may be classified into a manual cleaner in which a user directly moves the cleaner and cleans it, and an automatic cleaner in which the user runs autonomously and cleans it. The manual cleaners can be classified into canister (canister-type) cleaners, upright (upright) cleaners, hand-held cleaners, stick (stick-type) cleaners, etc. according to the type of the cleaner.

In recent years, there has been a trend toward a canister type cleaner and a stick type cleaner, which are integrated with a dust container and a cleaner body, so that the convenience of use is improved.

In the canister type cleaner, a main body and a suction port are connected by a rubber hose (hose) or a pipe (pipe), and a brush may be attached to the suction port according to circumstances to use the brush.

The hand-held cleaner (Hand Vacuum Cleaner) is a cleaner that maximizes portability, but may have a limitation in the area where cleaning is performed by sitting down due to its short length, although it is lightweight. Thus, it is used for cleaning local places such as desks, sofas or in automobiles.

The stick-type cleaner can be used standing, so that cleaning can be performed without bending down. Thus, the cleaning device can be moved in a wide area and cleaned. Compared with a handheld dust collector for cleaning a narrow space, the stick dust collector can clean a wider space and can clean a high place which cannot be reached by an adversary. In recent years, stick cleaners have been provided in a module form, and thus, the types of cleaners have been actively changed for various objects and used.

In addition, in recent years, a floor sweeping robot that autonomously performs cleaning without requiring an operation by a user has been used. The robot for cleaning automatically cleans an area to be cleaned by sucking foreign matter such as dust from the floor while autonomously traveling in the area to be cleaned.

However, since the capacity of the dust tub of the cleaner is limited, there is a problem in that a user is required to empty the dust tub every time.

In order to solve such a trouble, a dust collector base station having a dust collecting device, a dust storage part, and a dust bag has been developed to be able to automatically empty and store a dust bucket of the dust collector.

However, the existing base station of the dust collector captures the dust without separating the air and the dust, so that the air occupies a large volume inside the dust bag, and there is a problem in that it is difficult to remove the dust bag. In addition, there is a problem in that dust and air of the dust bag come off whenever the user removes the dust bag from the cleaner base station. The scattered dust not only pollutes the space of the user, but also can cause diseases such as respiratory diseases and the like.

Accordingly, there is a need for a dust collector base station and a control method thereof that can improve user convenience and sanitation by minimizing the volume of a dust bag by compressing dust of the dust collector base station and removing air, and preventing dust from scattering when removing the dust bag by sealing the dust bag.

Referring to fig. 1 to 4, a cleaner base station 100 of an embodiment of the present specification may incorporate a cleaner 200. The cleaner base station 100 can remove dust from the dust tub 220 of the cleaner 200.

First, the structure of the cleaner 200 will be described with reference to fig. 1 to 3.

The cleaner 200 may refer to a cleaner that a user manually operates. For example, the cleaner 200 may refer to a hand-held cleaner or a stick cleaner.

The cleaner 200 may be placed in the cleaner base station 100. The cleaner 200 may be supported by the cleaner base station 100. The cleaner 200 may be combined with the cleaner base station 100.

On the other hand, directions are defined below to aid understanding. In the present embodiment, the direction may be defined in a state where the cleaner 200 is placed in the cleaner base station 100 (refer to fig. 4).

The direction in which the cleaner 200 is exposed to the outside of the cleaner base station 100 when the cleaner 200 is placed on the cleaner base station 100 may be referred to as a front direction.

From a different point of view, the direction in which the suction motor 214 of the cleaner 200 is disposed when the cleaner 200 is placed in the cleaner base station 100 may be referred to as the front. The direction of the cleaner base station 100 opposite to the direction in which the suction motor 214 is disposed may be referred to as the rear direction.

The surface in the direction opposite to the front surface with reference to the inner space of the cover 110 may be referred to as the rear surface of the cleaner base station 100.

The left surface when the front surface is viewed with reference to the inner space of the cover 110 may be referred to as a left surface, and the right surface may be referred to as a right surface.

Accordingly, the left side surface may refer to a direction in which the third outer wall surface 112c is formed, and the right side surface may refer to a direction in which the fourth outer wall surface 112d is formed.

The surface in the direction opposite to the front surface with reference to the inner space of the cover 110 may be referred to as the rear surface of the cleaner base station 100. Thus, the back surface may refer to a direction in which the second outer wall surface 112b is formed.

The left surface when the front surface is viewed with reference to the inner space of the cover 110 may be referred to as a left surface, and the right surface may be referred to as a right surface. Thus, the left side surface may refer to a direction in which the third outer wall surface 112c is formed, and the right side surface may refer to a direction in which the fourth outer wall surface 112d is formed.

The cleaner 200 may include a main body 210. The main body 210 may include a main body cover 211, a suction portion 212, a dust separating portion 213, a suction motor 214, an air discharge cover 215, a handle 216, and an operating portion 218.

The main body cover 211 may form an external appearance of the cleaner 200. The main body cover 211 may provide a space in which the suction motor 214 and a filter (not shown) can be accommodated. The body cover 211 may be configured in a similar manner to a cylinder.

The suction portion 212 may protrude outward from the main body cover 211. As an example, the suction portion 212 may be formed in a cylindrical shape with an opened inside. The suction portion 212 may be combined with the extension pipe 250. The suction portion 212 may provide a flow path (hereinafter, may be referred to as a "suction flow path") through which air containing dust can flow.

On the other hand, in the present embodiment, a virtual line penetrating the inside of the suction portion 212 formed in a cylindrical shape may be formed.

The dust separating part 213 may communicate with the suction part 212. The dust separation part 213 may separate dust sucked into the inside through the suction part 212. The space inside the dust separating part 213 may communicate with the space inside the dust tub 220.

For example, the dust separating part 213 may have at least one cyclone part capable of separating dust by cyclone flow. The space inside the dust separating part 213 may communicate with the suction flow path. Accordingly, the air and dust sucked through the suction part 212 may spirally flow along the inner circumferential surface of the dust separating part 213. Accordingly, a cyclone flow may be generated in the inner space of the dust separating part 213.

The dust separating part 213 is in communication with the suction part 212 and is constructed using a principle of a dust collector using centrifugal force to separate dust sucked into the main body 210 through the suction part 212.

The dust separating part 213 may further include a secondary cyclone to re-separate dust from air discharged from the cyclone. At this time, the secondary cyclone may be located inside the cyclone to minimize the size of the dust separating part. The secondary cyclone may comprise a plurality of cyclone bodies arranged side by side. The air discharged from the cyclone may be split through a plurality of cyclone bodies.

At this time, the axis of the cyclone flow of the secondary cyclone may extend in the up-down direction, and the axis of the cyclone flow of the cyclone and the axis of the cyclone flow of the secondary cyclone may be formed coaxially in the up-down direction, which may be collectively referred to as the axis of the cyclone flow of the dust separating part 213.

The suction motor 214 may generate suction force to suck air. The suction motor 214 may be accommodated in the main body cover 211. The suction motor 214 may generate suction by rotating. As an example, the suction motor 214 may be formed similarly to a cylindrical shape.

On the other hand, in the present embodiment, a virtual suction motor axis extending the rotation shaft of the suction motor 214 may be formed.

The air discharge cover 215 may be disposed at one side of the main body cover 211 in the axial direction. A filter for filtering air may be accommodated in the air discharge cover 215. As an example, a high efficiency Particulate air filter (HEPA: HIGH EFFICIENCY Particulate AIR FILTER) may be accommodated in the air discharge cover 215.

An air discharge port 215a may be formed at the air discharge cover 215, and the air discharge port 215a discharges air sucked by suction force of the suction motor 214.

A flow guide may be provided at the air discharge cover 215. The flow guide may guide the flow of the air discharged through the air discharge port 215 a.

The handle 216 may be held by a user. The handle 216 may be disposed rearward of the suction motor 214. As an example, the handle 216 may be formed similarly to a cylindrical shape. Or the handle 216 may be formed in a curved cylindrical shape. The handle 216 may be disposed to form a prescribed angle with the main body cover 211 or the suction motor 214 or the dust separating part 213.

The handle 216 may include: a grip 216a formed in a column shape so that a user can grasp; a first extension portion 216b connected to one end portion of the grip portion 216a in the longitudinal direction (axial direction) and extending toward the suction motor 214; and a second extension portion 216c connected to the other end portion of the grip portion 216a in the longitudinal direction (axial direction) and extending toward the dust tub 220.

On the other hand, in the present embodiment, a virtual grip portion penetration line may be formed that extends along the longitudinal direction (the axial direction of the column) of the grip portion 216a and penetrates the grip portion 216 a.

As an example, the grip portion penetrating line may be a virtual line formed inside the cylindrical grip 216, and may be a virtual line parallel to at least a part of the outer surface (outer peripheral surface) of the grip portion 216 a.

The top surface of the handle 216 may form a portion of the appearance of the top surface of the cleaner 200. This prevents a part of the cleaner 200 from coming into contact with the arm of the user when the user grips the handle 216.

The first extension portion may extend from the grip portion 216a toward the main body cover 211 or the suction motor 214. At least a portion of the first extension may extend in a horizontal direction.

The second extension may extend from the grip 216a toward the dust bucket 220. At least a portion of the second extension may extend in a horizontal direction.

The operation portion 218 may be disposed on the handle 216. The operation portion 218 may be disposed on an inclined surface formed in an upper region of the handle 216. The user can input an operation or stop instruction of the cleaner 200 through the operation unit 218.

The cleaner 200 may include a dust bucket 220. The dust tub 220 may communicate with the dust separating part 213. The dust tub 220 may store dust separated at the dust separating part 213.

The dust barrel 220 may include a dust barrel body 221, a discharge cover 222, a dust barrel compression bar 223, and a compression member (not shown).

The dust tub body 221 may provide a space for storing dust separated at the dust separating part 213. As an example, the dust bucket body 221 may be formed similarly to a cylindrical shape.

On the other hand, in the present embodiment, a virtual dust-tub penetration line may be formed to penetrate the inside (inner space) of the dust-tub main body 221 and extend along the longitudinal direction of the dust-tub main body 221 (refer to the axial direction of the cylindrical dust-tub main body 221).

A portion of the rear surface of the dust bucket body 221 may be opened. In addition, a rear surface extension 221a may be formed at the rear surface of the dust tub body 221. The rear extension 221a may be formed to block a portion of the rear of the dust bucket body 221.

The dust bucket 220 may include a discharge cover 222. The discharge cover 222 may be disposed at the rear surface of the dust tub 220.

The discharge cover 222 may be provided to open and close one end portion of the dust barrel body 221 in the length direction. Specifically, the discharge cover 222 may selectively open and close the rear portion of the dust tub 220 opened downward.

The discharge cap 222 may include a cap main body 222a and a hinge portion 222b. The cover body 222a may be formed to block a portion of the rear surface of the dust tub body 221. The cover main body 222a can rotate downward with reference to the hinge portion 222b. The hinge portion 222b may be disposed adjacent to the battery housing 230. A torsion spring 222d may be provided at the hinge portion 222b. Thus, when the discharge cap 222 is separated from the dust barrel body 221, the cap body 222a can be supported by the elastic force of the torsion spring 222d so as to be rotated from the dust barrel body 221 by a predetermined angle or more about the hinge portion 222b.

The discharge cover 222 may be coupled with the dust tub 220 by a hook coupling. On the other hand, the discharge cover 222 may be separated from the dust tub 220 by a coupling lever 222 c. The coupling lever 222c may be disposed at an outer surface of the dust tub. The coupling lever 222c may elastically deform a hook formed extending from the cover main body 222a when an external force is applied, to release the hook coupling of the cover main body 222a and the dust bucket main body 221.

With the discharge cover 222 closed, the back surface of the dust bucket 220 may be blocked (sealed) by the discharge cover 222 and the back surface extension 221 a.

The dust bucket 220 may include a dust bucket compression bar 223 (refer to fig. 2). The dust barrel compression rod 223 may be disposed outside the dust barrel 220 or the dust separating part 213. The dust barrel compression bar 223 may be configured to linearly move back and forth outside the dust barrel 220 or the dust separating part 213. The dust bucket compression bar 223 may be connected to a compression member (not shown). In the case where the dust barrel compression bar 223 moves rearward by an external force, the compression member (not shown) may also move rearward together. Thereby, convenience for the user can be provided. The compressing piece (not shown) and the dust bucket compressing pole 223 may be returned to the original position by an elastic member (not shown). Specifically, in the case where the external force applied to the dust barrel compression bar 223 is removed, the elastic member may move the dust barrel compression bar 223 and the compression piece (not shown) forward.

A compressing member (not shown) may be disposed inside the dust bucket body 221. The compressing member may move in the inner space of the dust bucket body 221. Specifically, the compressing member may linearly move forward and backward within the dust barrel body 221. Thereby, the compressing piece can compress dust in the dust bucket body 221 rearward. In addition, in a case where the discharge cover 222 is separated from the dust barrel body 221 so that the rear of the dust barrel 220 is opened, the compressing piece may be moved from the front to the rear of the dust barrel 220, thereby removing foreign substances such as residual dust in the dust barrel 220. Thus, dust does not remain in the dust tub 220, and suction force of the cleaner can be improved. Further, malodor caused by residues can be eliminated by preventing dust from remaining in the dust tub 220.

The cleaner 200 may include a battery housing 230. A battery 240 may be accommodated in the battery case 230. The battery housing 230 may be disposed behind the handle 216. As an example, the battery cover 230 may have a hexahedral shape with one surface opened. One side of the battery housing 230 may be coupled to the handle 216.

The battery cover 230 may include a receiving portion opened rearward. The battery 240 is detachable from the housing of the battery cover 230.

The cleaner 200 may include a battery 240.

For example, the battery 240 may be detachably coupled to the cleaner 200. The battery 240 may be detachably coupled to the battery housing 230. As an example, the battery 240 may be inserted into the battery case 230 from below the battery case 230. With the above configuration, portability of the cleaner 200 can be improved.

In contrast, the battery 240 may be integrally provided inside the battery case 230. At this time, the back surface of the battery 240 is not exposed to the outside.

The battery 240 may supply power to the suction motor 214 of the cleaner 200. The battery 240 may be disposed at the rear of the handle 216. The battery 240 may be disposed above the dust tub 220.

In the case where the battery 240 is coupled to the battery case 230, the rear surface of the battery 240 may be exposed to the outside. The battery 240 may be placed on the floor when the cleaner 200 is placed on the floor, so that the battery 240 may be directly separated from the battery housing 230. In addition, since the rear surface of the battery 240 is exposed to the outside to be in direct contact with the outside air of the battery 240, the cooling performance of the battery 240 can be improved.

On the other hand, in the case where the battery 240 is integrally fixed to the battery cover 230, the structure for attaching and detaching the battery 240 and the battery cover 230 can be omitted, and therefore the overall size of the vacuum cleaner 200 can be reduced, and the vacuum cleaner can be made lightweight.

The cleaner 200 may include an extension tube 250. Extension tube 250 may be in communication with a sweeper module 260. The extension tube 250 may be in communication with the body 210. The extension pipe 250 may communicate with the suction portion 212 of the body 210. The extension pipe 250 may be formed in a long cylindrical shape.

The body 210 may be connected with an extension tube 250. The body 210 may be connected to the cleaning module 260 using an extension tube 250. The main body 210 may generate suction through the suction motor 214 and provide suction to the cleaning module 260 through the extension pipe 250. External dust may flow into the main body 210 through the cleaning module 260 and the extension pipe 250.

The cleaner 200 may include a cleaning module 260. The sweeper module 260 may be in communication with the extension tube 250. Thus, by the suction force generated in the main body 210 of the cleaner 200, the outside air can flow into the main body 210 of the cleaner 200 via the cleaning module 260 and the extension pipe 250.

Dust in the dust tub 220 of the cleaner 200 may be caught to the dust collecting part 170 of the cleaner base station 100 due to the gravity and the suction force of the dust collecting motor 191. Accordingly, dust in the dust tub can be removed without additional operation of a user, and thus user convenience can be improved. In addition, the trouble of requiring the user to empty the dust bucket each time can be eliminated. In addition, dust can be prevented from scattering when the dust bucket is emptied.

The cleaner 200 may be combined with the front surface of the cover 110. Specifically, the main body 210 of the cleaner 200 may be placed at the coupling part 120. More specifically, the dust barrel 220 and the battery housing 230 of the dust collector 200 may be coupled to the coupling surface 121, the outer circumferential surface of the dust barrel body 221 may be coupled to the dust barrel guide surface 122, and the suction part 212 may be coupled to the suction part guide surface 126 of the coupling part 120. In this case, the central axis of the dust tub 220 may be disposed in a direction parallel to the ground, and the extension pipe 250 may be disposed in a direction perpendicular to the ground.

Next, a cleaner base station 100 according to the present invention will be described with reference to fig. 5 to 10.

The cleaner 200 may be incorporated in the cleaner base station 100. Specifically, the main body of the cleaner 200 may be coupled to the front surface of the cleaner base station 100. The cleaner base station 100 can remove dust inside the dust tub 220 of the cleaner 200.

The cleaner base station 100 can include a housing 110. The cover 110 may form an external appearance of the cleaner base station 100, and a space may be formed inside the cover 110. Specifically, the cover 110 may be formed in a column shape including at least one outer wall surface. As an example, the cover 110 may be formed in a similar shape to a quadrangular prism.

A space capable of accommodating the dust collection part 170 and the dust suction module 190 may be formed in the cover 110, dust is stored in the dust collection part 170, and the dust suction module 190 generates a flow force to collect the dust to the dust collection part 170.

The housing 110 may include a bottom surface 111, an outer wall surface 112, and a top surface 113.

The bottom surface 111 may support a gravitational lower side of the dust suction module 190. That is, the bottom surface 111 may support the underside of the dust collecting motor 191 of the dust suction module 190.

At this time, the bottom surface 111 may be configured to face the ground. The bottom surface 111 may be disposed not only parallel to the ground but also inclined at a predetermined angle to the ground. With the above configuration, the dust collection motor 191 can be stably supported, and the overall weight can be balanced even when the cleaner 200 is coupled.

On the other hand, the bottom surface 111 may further include a ground support portion 111a that increases the area of contact with the ground to prevent the cleaner base station 100 from falling down and maintaining balance. As an example, the floor support portion 111a may be formed in a plate shape extending from the bottom surface 111, or may be formed by one or more frames extending from the bottom surface 111 in a protruding manner in the floor direction.

The outer wall surface 112 may be a surface formed along the gravity direction, and may be a surface connected to the bottom surface 111. For example, the outer wall surface 112 may refer to a surface that is perpendicularly connected to the bottom surface 111. As a different example, the outer wall surface 112 may be inclined at a predetermined angle with respect to the bottom surface 111.

The outer wall surface 112 may include at least one surface. As an example, the outer wall surface 112 may include a first outer wall surface 112a, a second outer wall surface 112b, a third outer wall surface 112c, and a fourth outer wall surface 112d.

At this time, in the present embodiment, the first outer wall surface 112a may be disposed on the front surface of the cleaner base station 100. Here, the front surface may be a surface on which the cleaner 200 is exposed in a state where the cleaner 200 is coupled to the cleaner base station 100. Thereby, the first outer wall surface 112a can form the appearance of the front surface of the cleaner base station 100.

The first outer wall surface 112a may be formed not only in a planar shape but also in a curved shape as a whole, or may be formed so that a part thereof includes a curved surface.

The first outer wall surface 112a may be provided with a joint 120. With this configuration, the cleaner 200 can be coupled to the cleaner base station 100 and supported by the cleaner base station 100. The specific configuration of the joint 120 will be described later.

On the other hand, a structure for placing the cleaning module 260 of various forms used in the cleaner 200 may be added to the first outer wall surface 112 a.

In the present embodiment, the second outer wall surface 112b may be a surface facing the first outer wall surface 112 a. That is, the second outer wall surface 112b may be disposed on the back surface of the cleaner base station 100. The second outer wall 112b may form the appearance of the rear surface of the cleaner base station 100.

In the present embodiment, the third outer wall surface 112c and the fourth outer wall surface 112d may refer to surfaces connecting the first outer wall surface 112a and the second outer wall surface 112 b. In this case, the third outer wall surface 112c may be disposed on the left side surface of the cleaner base station 100, and the fourth outer wall surface 112d may be disposed on the right side surface of the cleaner base station 100. In contrast, the third outer wall surface 112c may be disposed on the right side surface of the cleaner base station 100, and the fourth outer wall surface 112d may be disposed on the left side surface of the cleaner base station 100.

The third outer wall surface 112c or the fourth outer wall surface 112d may be formed not only in a planar shape but also in a curved shape as a whole, or may be formed so that a part thereof includes a curved surface.

On the other hand, a structure for placing the cleaning module 290 of various forms used in the cleaner 200 may be added to the third outer wall surface 112c or the fourth outer wall surface 112 d.

The top face 113 may form an upper side appearance of the cleaner base station. That is, the top surface 113 may be a surface disposed at the uppermost side in the gravitational direction in the cleaner base station and exposed to the outside.

For reference, in the present embodiment, the upper side and the lower side may refer to the upper side and the lower side in the gravity direction (the direction perpendicular to the floor) in a state where the cleaner base station 100 is disposed on the floor.

In this case, the top surface 113 may be disposed not only parallel to the ground but also inclined at a predetermined angle to the ground.

A display portion may be provided on the top surface 113. For example, the state of the cleaner base station 100 and the state of the cleaner 200 may be displayed on the display unit, and information such as the cleaning progress status and a map for the cleaning area may be displayed.

On the other hand, the top surface 113 may be provided to be separable from the outer wall surface 112. At this time, when the top surface 113 is separated, a battery separated from the cleaner 200 may be accommodated in an inner space surrounded by the outer wall surface 112, and a terminal (not shown) capable of charging the separated battery may be provided.

On the other hand, a bag receiving space 115 may be formed inside the cover 110. The bag accommodating space 115 may be disposed at a gravitational lower side of the coupling part 120 and may be disposed at a gravitational upper side of the dust suction module 190.

A dust collection part 170 may be provided in the bag accommodating space 115. Specifically, the bag supporting portion 173 to be described later may be accommodated in the bag accommodating space 115 so as to be able to come in and go out. The dust bag box 174 described later may be detachably coupled to the bag accommodating space 115. Further, an adapter 176 to be described later may be attached to the bag accommodating space 115. Further, a bag compressing member 177 described later may be disposed in the bag accommodating space 115. The bag accommodating space 115 may communicate with a first flow path 181, a second flow path 182, and a bypass flow path 183, which will be described later. With the above-described configuration, the bag accommodating space 115 can provide a space capable of flowing and trapping air and dust flowing from the dust bucket 220 to the dust bag 172, and capable of compressing and sealing the dust bag 172.

On the other hand, a state in which the cleaner 200 is coupled to the cleaner base station 100 will be described with reference to fig. 4 and 10.

In the present invention, the cleaner 200 may be placed on the outer wall surface 112 of the cleaner base station 100. As an example, the dust bucket 220 and the battery cover 230 of the cleaner 200 may be coupled to the coupling surface 121 of the cleaner base station 100. That is, the cleaner 200 may be placed on the first outer wall surface 112a.

At this time, the axis of the suction motor 214 may be formed to be perpendicular to the first outer wall surface 112 a. That is, the axis of the suction motor 214 may be formed parallel to the ground.

An imaginary line penetrating the dust tub 220 may be formed to be perpendicular to the first outer wall surface 112 a.

The longitudinal axis C of the cover 110 may be formed to be perpendicular to the ground. The longitudinal axis C of the cover 110 may be formed parallel to at least one of the first outer wall surface 112a, the second outer wall surface 112b, the third outer wall surface 112C, and the fourth outer wall surface 112 d.

In the case where the cleaner 200 is coupled to the cleaner base station 100, the axis of the suction motor 214 may intersect with the longitudinal axis of the cleaner base station 100. That is, the rotation axis of the suction motor 214 may intersect the longitudinal axis of the cleaner base station 100.

In addition, in the case where the cleaner 200 is coupled to the cleaner base station 100, the battery 240 may be disposed at a position farther from the floor than the rotation axis of the suction motor 214 with reference to the floor. With this configuration, the cleaner 200 can be stably supported by the cleaner base station 100.

In the case where the cleaner 200 is coupled to the cleaner base station 100, an imaginary line passing through the dust bucket 220 may intersect with a longitudinal axis of the cleaner base station 100. That is, the longitudinal axis of the dust tub 220 may intersect with the longitudinal axis of the cleaner base station 100. At this time, the intersection of the longitudinal axis of the dust bucket 220 and the longitudinal axis of the cleaner base station 100 may be located inside the housing 110, more specifically, inside the flow path portion 180.

On the other hand, in the case where the cleaner 200 is coupled to the cleaner base station 100, the handle 216 may be disposed at a position farther from the floor than an imaginary line penetrating the dust bucket 220 with respect to the floor. With the above configuration, it is possible to provide convenience in that the user can attach or detach the cleaner 200 to or from the cleaner base station 100 by a simple operation of moving the cleaner 200 in the direction parallel to the floor surface when the user holds the handle 216.

Next, the joint 120 of the cleaner base station 100 according to the present invention will be described with reference to fig. 5.

The cleaner base station 100 may include a coupling part 120 for coupling the cleaner 200. Specifically, the coupling portion 120 may be disposed on the first outer wall surface 112a, and the main body 210, the dust bucket 220, and the battery case 230 of the cleaner 200 may be coupled to the coupling portion 120.

The bonding portion 120 may include a bonding surface 121. The bonding surface 121 may be disposed on the front surface of the cover 110. As an example, the joint surface 121 may be formed as a groove recessed from the first outer wall surface 112a toward the inside of the cleaner base station 100. That is, the joint surface 121 may be a surface formed to form an end with the first outer wall surface 112 a.

The cleaner 200 may be coupled to the coupling surface 121. As an example, the coupling surface 121 may contact the rear surfaces of the dust tub 220 and the battery housing 230 of the cleaner 200.

As an example, the angle formed by the joint surface 121 and the ground may be a right angle. Thereby, the space of the cleaner base station 100 when the cleaner 200 is coupled to the coupling surface 121 can be minimized.

As another example, the coupling surface 121 may be obliquely disposed to form a prescribed angle with the ground. Thus, the cleaner base station 100 can be stably supported with the cleaner 200 coupled to the coupling surface 121.

Dust passing holes 121a may be formed at the coupling surface 121 to allow air outside the cover 110 to flow into the inside. The dust passing hole 121a may be formed in a hole shape corresponding to the shape of the dust tub 220 so that the dust of the dust tub 220 flows into the dust collecting part 170. The dust passing hole 121a may be formed corresponding to the form of the discharge cap 222 of the dust tub 220. The dust passage hole 121a may be formed to communicate with a flow path portion 180 described later.

The junction 120 may include a dust bucket guide surface 122. The dust bucket guide surface 122 may be disposed at the first outer wall surface 112a. The dirt bucket guide surface 122 may be coupled to the first outer wall surface 112a. In addition, the dust bucket guide surface 122 may be connected with the coupling surface 121.

The dust bucket guide surface 122 may be formed in a shape corresponding to an outer side surface of the dust bucket 220. A lower outer side of the dust bucket 220 may be incorporated into the dust bucket guide 122. Thereby, the convenience of coupling the cleaner 200 to the coupling surface 121 can be provided.

On the other hand, a protrusion moving hole 122a may be formed in the dust barrel guide surface 122, and a pressing protrusion 151, which will be described later, may move linearly along the protrusion moving hole 122 a. A gear case 155 for accommodating a gear of the lid opening unit 150 described later, or the like may be provided on the lower side of the dust barrel guide surface 122 in the gravitational direction. At this time, a guide space 122b, in which the pressing protrusion 151 is movable, may be formed between the lower side of the dust bucket guide surface 122 and the upper side of the gear case 155. Also, the guide space 122b may communicate with the first flow path 181 using a bypass hole 122 c. That is, the boss moving hole 122a, the guide space 122b, the bypass hole 122c, and the first flow path 181 may form one flow path. With the above configuration, when the dust collection motor 191 is operated in a state where the dust tub 220 is coupled to the coupling portion 120, dust remaining in the dust tub 220 and the dust tub guide surface 122 can be sucked through the flow path.

The coupling portion 120 may include a guide protrusion 123. The guide protrusion 123 may be disposed at the coupling surface 121. The guide protrusion 123 may protrude upward from the coupling surface 121. The guide protrusions 123 may be provided in two spaced apart from each other. The distance between the two guide protrusions 123 spaced apart from each other may correspond to the width of the battery housing 230 of the cleaner 200. Thereby, the convenience of coupling the cleaner 200 to the coupling surface 121 can be provided.

The bond 120 may include a bond sidewall 124. The joint side walls 124 may be wall surfaces disposed on both side surfaces of the joint surface 121, and may be connected perpendicularly to the joint surface 121. The joint side wall 124 may be connected with the first outer wall surface 112 a. In addition, the bond side walls 124 may form a surface that interfaces with the dirt bucket guide surface 122. This allows the cleaner 200 to be stably accommodated.

The bond 120 may include a bond sensor 125. The coupling sensor 125 may sense whether the cleaner 200 is coupled to the coupling part 120.

The bond sensor 125 may also include a contact sensor. As an example, the combination sensor 125 may include a micro switch (micro switch). At this time, the coupling sensor 125 may be disposed at the guide protrusion 123. Accordingly, the battery housing 230 or the battery 240 of the cleaner 200 may be in contact with the coupling sensor 125 while being coupled between the pair of guide protrusions 123, and the coupling sensor 125 may sense coupling of the cleaner 200.

On the other hand, the combination sensor 125 may also include a non-contact sensor. As an example, the combination sensor 125 may include an infrared sensor (IR sensor). At this time, the bonding sensor 125 may be disposed at the bonding portion sidewall 124. Thus, the bond sensor 125 may sense the presence of the dust bucket 220 or the main body 210 of the cleaner 200 when the dust bucket 220 or the main body 210 passes the bond sidewall 124 and reaches the bond surface 121.

The coupling sensor 125 may face the dust bucket 220 or the battery housing 230 of the cleaner 200 in a state where the cleaner 200 is coupled to the cleaner base station 100.

The combination sensor 125 may be a device that determines whether the cleaner 200 has been combined based on whether power is applied to the battery 240 of the cleaner 200.

The junction 120 may include a suction guide surface 126. The suction portion guide surface 126 may be disposed on the first outer wall surface 112a. The suction portion guide surface 126 may be connected with the dust bucket guide surface 122. The suction portion 212 may be incorporated into the suction portion guide surface 126. The shape of the suction portion guide surface 126 may correspond to the shape of the suction portion 212.

The coupling part 120 may further include a fixing member access hole 127. The fixing member access hole 127 may be formed in a long hole form along the coupling portion side wall 124 to allow the fixing member 131 to be accessed.

With this configuration, when the user couples the cleaner 200 to the coupling portion 120 of the cleaner base station 100, the main body 210 of the cleaner 200 can be stably disposed on the coupling portion 120 by the dust bucket guide surface 122, the guide projection 123, and the suction portion guide surface 126. Thereby, the convenience of coupling the dust tub 220 and the battery housing 230 of the cleaner 200 to the coupling surface 121 can be provided.

On the other hand, the cleaner base station 100 may further include a charging part 128. The charging portion 128 may be disposed at the coupling portion 120. The charging part 128 may be electrically connected with the cleaner 200 coupled to the coupling part 120. The charging part 128 may supply power to the battery of the cleaner 200 combined with the combining part 120.

In addition, the cleaner base station 100 may further include a side door (not shown). The side door may be disposed at the cover 110. The side door may selectively expose the dust collection part 170 to the outside. Thus, the user can easily remove the dust bag 172 from the cleaner base station 100.

The fixing unit 130 of the present invention will be described with reference to fig. 6.

The cleaner base station 100 of the present invention may include a fixing unit 130. The fixing unit 130 may be disposed at the coupling portion sidewall 124. In addition, the fixing unit 130 may be disposed at the rear surface of the coupling surface 121. The fixing unit 130 may fix the cleaner 200 coupled with the coupling surface 121. Specifically, the fixing unit 130 may fix the dust bucket 220 and the battery housing 230 of the dust collector 200 coupled with the coupling surface 121.

The fixing unit 130 may include: a fixing member 131 for fixing the dust tub 220 and the battery cover 230 of the cleaner 200; and a fixing portion motor 133 driving the fixing member 131. In addition, the fixing unit 130 may further include a fixing portion coupler 135 transmitting power of the fixing portion motor 133 to the fixing member 131.

The fixing member 131 may be disposed at the coupling portion sidewall 124 and provided to be capable of reciprocating at the coupling portion sidewall 124 to fix the dust tub 220. Specifically, the fixing member 131 may be accommodated inside the fixing member access hole 127.

The fixing members 131 may be disposed at both sides of the coupling portion 120, respectively. As an example, the two fixing members 131 may be arranged in pairs symmetrically about the joint surface 121.

The fixing portion motor 133 may provide power to move the fixing member 131.

The fixed part coupler 135 may convert the rotational force of the fixed part motor 133 into the reciprocating movement of the fixed member 131.

The stationary seal 136 may be configured to seal against the dirt cup 220 when the dirt cup guide surface 122 is coupled to the cleaner 200. With the above-described configuration, when the dust bucket 220 of the dust collector 200 is combined, the self weight of the dust collector 200 can pressurize the fixed seal 136, and the dust bucket 220 and the dust bucket guide surface 122 can be sealed.

The fixing seal 136 may be disposed on an imaginary extension line of the fixing member 131. With the above-described configuration, when the fixing portion motor 133 is operated so that the fixing member 131 pressurizes the dust bucket 220, the circumference of the dust bucket 220 at the same height can be sealed.

According to an embodiment, the fixing seal 136 may be disposed on the dust bucket guide surface 122 in a bent line shape corresponding to the disposition of the cover opening unit 150 described later.

Thus, in the case where the main body 210 of the cleaner 200 is disposed at the coupling portion 120, the fixing unit 130 can fix the main body 210 of the cleaner 200. Specifically, in the case where the coupling sensor 125 senses that the main body 210 of the cleaner 200 is coupled to the coupling part 120 of the cleaner base station 100, the fixing part motor 133 may fix the main body 210 of the cleaner 200 by moving the fixing member 131.

Therefore, dust can not remain in the dust barrel, and the suction force of the dust collector can be improved. In addition, malodor caused by residues can be removed by preventing dust from remaining in the dust tub.

Next, the gate unit 140 of the present invention will be described with reference to fig. 7 and 8.

The cleaner base station 100 of the present invention may include a door unit 140. The door unit 140 may be configured to be capable of opening and closing the dust passing 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 hinge-coupled to the coupling surface 121, and may open and close the dust passing hole 121a. The door 141 may include a door main body 141a.

The door body 141a may be formed in a form capable of blocking the dust passing hole 121 a. As an example, the door body 141a may be formed similarly to a disk shape.

A hinge portion may be disposed at an upper side of the door body 141a and an arm coupling portion 141b may be disposed at a lower side of the door body 141a, based on a state where the door body 141a blocks the dust passing hole 121 a.

The door body 141a may be formed in a form capable of airtight dust passing through the hole 121 a. As an example, the outer surface of the door body 141a exposed to the outside of the cleaner base station 100 has a diameter corresponding to the diameter of the dust passing hole 121a, and the inner surface disposed inside the cleaner base station 100 has a diameter larger than the diameter of the dust passing hole 121 a. In addition, a step may be formed between the outer side and the inner side. On the other hand, at least one reinforcing rib for connecting the hinge portion and the arm coupling portion 141b and reinforcing the supporting force of the door main body 141a may be convexly formed at the inner side surface.

The hinge portion may be a mechanism for hinge-coupling the door 141 to the coupling surface 121. The hinge portion may be disposed at an upper end portion of the door body 141a and coupled to the coupling surface 121.

The arm coupling portion 141b may be a mechanism to which the door arm 143 is rotatably coupled. The arm coupling portion 141b may be disposed at a lower side of the door main body 141a, and may be rotatably coupled to the door main body 141a, and the door arm 143 may be rotatably coupled to the arm coupling portion 141b.

With the above-described configuration, when the door arm 143 pulls the door body 141a in a state where the door 141 closes the dust passage hole 121a, the door body 141a can be rotatably moved toward the inside of the cleaner base station 100 with the hinge portion as an axis, and the dust passage hole 121a can be opened. On the other hand, when the door arm 143 pushes the door body 141a in a state where the dust passing hole 121a is opened, the door body 141a may be rotatably moved toward the outside of the cleaner base station 100 about the hinge portion 141b, and the dust passing hole 121a may be blocked.

On the other hand, in a state where the cleaner 200 is coupled to the cleaner base station 100 and the discharge cover 215 is separated from the dust bucket body 210, the door 141 may be in contact with the discharge cover 215. Further, the discharge cap 215 may be interlocked with and rotated with the door 141 as the door 141 rotates.

The door motor 142 may provide power to rotate the door 141.

Specifically, the door motor 142 may rotate the door arm 143 in a forward direction or a reverse direction. Here, the positive direction may refer to a direction in which the door arm 143 pulls the door 141. Therefore, when the door arm 143 rotates in the forward direction, the dust passing hole 121a may be opened. In addition, the opposite direction may refer to a direction in which the door arm 143 pushes the door 141. Therefore, when the door arm 143 rotates in the opposite direction, at least a portion of the dust passing hole 121a may be blocked. The forward direction may be the opposite direction from the reverse direction.

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

As an example, the door arm 143 may include a first door arm 143a and a second door arm 143b. One side end of the first door arm 143a may be coupled to the door motor 142. The first door arm 143a may be rotated by power of the door motor 142. The other side end portion of the first door arm 143a may be rotatably coupled with the second door arm 143b. The first door arm 143a may transmit the force received from the door motor 142 to the second door arm 143b. One side end of the second door arm 143b may be coupled with the first door arm 143 a. The other side end of the second door arm 143b may be coupled with the door 141. The second door arm 143b may open and close the dust passing hole 121a by pushing or pulling the door 141.

The door unit 140 may further include a door opening and closing sensing part 144. The door opening and closing sensing part 144 may be provided inside the cover 110 and sense whether the door 141 is in an open state.

As an example, the door opening/closing sensing portions 144 may be disposed at both side ends of the rotation movement region of the door arm 143, respectively. As another example, the door opening and closing sensing parts 144 may be respectively disposed at both side ends of the moving area of the door 141.

Thus, when the door arm 143 moves to the door opening position DP1 set in advance or the door 141 is opened to a prescribed position, the door opening/closing sensing part 144 can sense that the door has been opened. In addition, when the door arm 143 moves to a preset door closing position DP2 or the door 141 is opened to a prescribed position, the door opening/closing sensing part 144 may sense that the door has been opened.

The door opening and closing sensing part 144 may also include a contact sensor. As an example, the door opening/closing sensing portion 144 may include a micro switch (micro switch).

On the other hand, the door opening/closing sensing portion 144 may include a non-contact sensor. As an example, the door opening/closing sensing unit 144 may include an infrared sensor unit (IR sensor).

With this configuration, the door unit 140 can communicate the outside of the first outer wall surface 112a with the flow path portion 180 and/or the dust collection portion 170 by selectively opening and closing at least a portion of the joint surface 121.

The door unit 140 may be opened together when the discharge cover 222 of the cleaner 200 is opened. In addition, when the door unit 140 is closed, the discharge cover 222 of the cleaner 200 may be closed together with this.

In case that dust of the dust tub 220 of the dust collector 200 is removed, the door motor 142 may couple the discharge cover 222 to the dust tub body 221 by rotating the door 141. Specifically, the door motor 142 may rotate the door 141 with respect to the hinge portion 141b by rotating the door 141, and the door 141 rotated with respect to the hinge portion 141b may push the discharge cover 222 toward the dust bucket body 221.

Next, the cover opening unit 150 according to the present invention will be described with reference to fig. 9.

The cleaner base station 100 of the present invention may include a cover opening unit 150. The cover opening unit 150 may be disposed at the coupling part 120, and may open the discharge cover 222 of the cleaner 200.

The cover opening unit 150 may include a pressing protrusion 151, a cover opening motor 152, a cover opening gear 153, a support plate 154, and a gear case 155.

The pressing protrusion 151 may be moved to press the coupling lever 222c upon coupling of the cleaner 200.

The pressing protrusion 151 may be disposed at the dust bucket guide surface 122. Specifically, a protrusion moving hole may be formed at the dust tub guide surface 122, and the pressing protrusion 151 may be exposed to the outside through the protrusion moving hole.

The pressing protrusion 151 may be disposed at a position where the coupling lever 222c can be pressed when the cleaner 200 is coupled. That is, the coupling lever 222c may be disposed on the boss moving hole. In addition, the coupling lever 222c may be disposed on a moving region of the pressing protrusion 151.

The pressing projection 151 may reciprocate linearly to press the bonding rod 222 c. Specifically, the pressing protrusion 151 may be guided to move linearly by being coupled to the gear case 155. The pressing protrusion 151 may be coupled with the cover opening gear 153 and moved together by the movement of the cover opening gear 153.

The cover opening motor 152 may provide power to move the pressing protrusion 151. Specifically, the cover opening motor 152 may rotate a motor shaft (not shown) in a forward direction or a reverse direction. Here, the positive direction may refer to a direction in which the pressing protrusion 151 presses the coupling lever 222 c. In addition, the opposite direction may mean that the pressing protrusion 151 of the pressing coupling lever 222c is returned to the home direction. The forward direction may be the opposite direction from the reverse direction.

The cover opening gear 153 may be coupled to the cover opening motor 152 and move the pressing protrusion 151 by power of the cover opening motor 152. Specifically, the cover opening gear 153 may be accommodated inside the gear case 155. The driving gear 153a of the cover opening gear 153 may receive power by being coupled with a motor shaft of the cover opening motor 152. The driven gear 153b of the cover opening gear 153 may move the pressing protrusion 151 by being combined with the pressing protrusion 151. As an example, the driven gear 153b may be provided in a rack form and engaged with the driving gear 153a, and may receive power from the driving gear 153 a.

At this time, a torsion spring 222d may be provided at the discharge cap 222. The discharge cap 222 can be rotated by a predetermined angle or more by the elastic force of the torsion spring 222d, and is supported at the rotated position. Thereby, the discharge cover 222 may be opened, and the dust passing hole 121a may be communicated with the inside of the dust tub 220.

The gear case 155 may be provided inside the cover 110 and disposed at a lower side of the coupling portion 120 in the gravitational direction, and accommodates the cover opening gear 153 inside.

A cover opening sensing part 155f may be provided at the gear case 155. At this time, the cover opening sensing part 155f may include a contact sensor. As an example, the cover opening sensing part 155f may include a micro switch (micro switch). On the other hand, the cover opening sensing part 155f may include a non-contact sensor. As an example, the cover opening sensing portion 155f may include an infrared sensor portion (IR sensor).

The cover opening sensing portion 155f may be disposed on at least one of an inner side surface and an outer side surface of the gear case 155. As an example, the cover opening sensing portion 155f may be disposed on the inner side surface of the gear case 155. At this time, the cover opening sensing part 155f may sense that the pressing protrusion 151 is located at the initial position.

Therefore, according to the present invention, by the cover opening unit 150, the user can open the dust bucket 220 without additionally opening the discharge cover 222 of the cleaner, so that convenience can be improved.

In addition, since the discharge cover 222 is opened in a state where the cleaner 200 is coupled to the cleaner base station 100, there is an effect that dust can be prevented from scattering.

On the other hand, the dust collection unit 170 will be described with reference to fig. 10 to 16.

The cleaner base station 100 may include a dust collection part 170. The dust collection part 170 may be disposed inside the cover 110. The dust collection part 170 may be disposed at a lower side of the coupling part 120 in the gravitational direction.

The dust collecting part 170 may collect dust inside the dust tub 220 of the dust collector 200. Specifically, when the dust collection motor 191 is operated in a state where the cleaner 200 is coupled to the cleaner base station 100 and the inside of the dust bucket 220 is in communication with the flow path portion 180, dust inside the dust bucket 220 may flow along the flow path portion 180 and be trapped in the dust collection portion 170.

The dust collection part 170 may include a dust separation part 171, a dust bag 172, a bag support part 173, a dust bag box 174, a prefilter 175, and an adapter 176 and a bag compression member 177.

The dust separating part 171 may separate dust in the air flowing from the dust tub 220.

The dust separating part 171 may communicate with the first flow path 181. The dust separating part 171 may separate dust sucked into the inside through the first flow path 181. The space inside the dust separating part 171 may communicate with the space inside the bag supporting part 173.

For example, the dust separating part 171 may be provided with at least one cyclone part capable of separating dust by cyclone flow. Accordingly, the air and dust flowing in through the first flow path 181 flow spirally along the inner peripheral surface of the dust separating part 171. Thereby, a cyclone flow can be generated in the inner space of the dust separating part 171.

The dust separating part 171 is in communication with the first flow path 181 and is constructed using a principle of a dust collector using centrifugal force to separate dust flowing into the inside of the cover 110 through the dust passing hole 121 a.

The dust separating part 171 may further include a secondary cyclone to re-separate dust from air discharged from the cyclone. At this time, the secondary cyclone may be located inside the cyclone to minimize the size of the dust separating part 171. The secondary cyclone may comprise a plurality of cyclone bodies arranged side by side. The air discharged from the cyclone can be split through a plurality of cyclone bodies

The dust bag 172 may be disposed inside the housing 110. The dust bag 172 may be disposed at a lower side of the dust separation part 171 in the gravitational direction.

The dust bag 172 may be formed of a non-permeable material. For example, the dust bag 172 may include a roll of plastic (not shown). With the above configuration, when the dust bag 172 is sealed or joined, the dust or malodor trapped inside the dust bag 172 can be prevented from leaking outside the dust bag 172.

The dust bag 172 may be mounted to the housing 110 using a dust bag box 174. The dust bag 172 may be replaced by a dust bag box 174 as needed. That is, the dust collection part 170 may be defined as a consumable part. The dust bag 172 may be enlarged in volume by suction force (negative pressure) generated when the dust collecting motor 191 is operated in a state of being mounted to the housing 110.

At this time, the dust bag 172 in the unfolded state may be accommodated inside the bag supporting portion 173. That is, when the dust collecting motor 191 is operated, the dust bag 172 may be inflated within the bag supporting part 173. Thereafter, the dust bag 172 in the unfolded state may be supported by the bag support 173 so that the shape is maintained.

The dust bag 172 may store dust separated at the dust separating part 171. The upper region of the dust bag 172 may be severed and engaged by the adapter 176. The dust bag 172 may be separated from the bag support 173 in a state where the upper region is cut and engaged.

With this configuration, the user does not need to additionally bind a bag or the like in which dust is trapped, and thus the user's convenience can be improved.

The bag support 173 may support the dust bag 172. The bag support 173 may accommodate the dust bag 172 inside with the dust bag 172 inflated. The bag support 173 may support the outer shape of the inflated dust bag 172.

Specifically, the pouch support 173 may include a support body 173a and a suction hole 173b.

The support body 173a may be detachably coupled inside the cover 110. For example, the supporting portion body 173a may be formed in a cylindrical shape, and the wheels 173c may be provided at a lower side of the supporting portion body 173 a. At this time, the outer circumferential surface of the supporting portion main body 173a may be disposed to be spaced apart from the sidewall of the bag accommodating space 115. Thereby, a space may be formed between the outer circumferential surface of the support portion main body 173a and the side wall of the bag accommodating space 115. Further, a space may be formed between the lower side surface of the support part body 173a and the lower side surface of the bag accommodating space 115. The space may provide a path for transferring the suction force of the dust collecting motor 191.

With the above configuration, when the dust collection motor 191 is operated, air present in the bag accommodating space 115 can be sucked into the dust collection motor 191 by the suction force of the dust collection motor 191, and a negative pressure for expanding the dust bag 172 can be formed in the bag accommodating space 115.

The support body 173a may be formed to be able to accommodate the dust bag 172 inside in the case where the dust bag 172 is inflated. For example, the supporting portion body 173a may be formed in a cylindrical shape, an upper side surface of the supporting portion body 173a may be opened, and a lower side surface of the supporting portion body 173a may be formed in a shape in which at least a part thereof is blocked. At this time, at least a portion of the dust bag 172 may be disposed on the upper side of the support part body 173 a. When the dust bag 172 is inflated, the inner space of the support body 173a can be filled as the dust bag 172 is inflated downward.

The suction holes 173b may be formed in plural in the support portion main body 173 a. For example, the adsorption hole 173b may be formed in plural along the outer circumferential surface of the support portion main body 173 a. Further, at least one suction hole 173b may be formed on the lower side surface of the support portion main body 173 a. With the above configuration, when the dust collection motor 191 is operated, air inside the support portion main body 173a can flow outside the support portion main body 173a through the suction holes 173 b. In a state where the dust bag 173b is inflated inside the support portion main body 173a, a negative pressure toward the outside of the support portion main body 173a may be applied to the dust bag 172, and the dust bag 172 may be inflated so as to be in close contact with the inner peripheral surface and the lower side surface of the support portion main body 173 a. That is, the dust bag 172 may be inflated along the inner form of the bag support 173.

In particular, in the case where the plurality of suction holes 173b are formed to maintain the prescribed interval, the negative pressure can be applied uniformly to the entire dust bag 172, so that the dust bag 172 can be uniformly inflated and maintained in the inflated state.

On the other hand, the pouch support 173 may be provided to be able to be drawn out from the inside of the case 110.

Specifically, the pouch support 173 may be provided in the pouch receiving space 115 formed inside the cover 110. At this time, a structure for guiding the linear movement of the pouch support 173 may be provided in the pouch support 173. As an example, as shown in fig. 17, a plurality of wheels 173c may be provided in the bag supporting portion 173. That is, a plurality of wheels 173c may be provided on the lower side surface of the supporting portion main body 173 a. As another example, although not shown, a guide rail may be formed at a side surface of the bag supporting portion 173.

With the above configuration, the user can open a side door (not shown) of the cleaner base station 100 and then draw the dust bag 172 out of the cover 110 by pulling the bag support 173. Thus, according to the present invention, the user can easily take out the dust bag and discard it.

The dust bag box 174 may be detachably coupled to the housing 110 and supply the dust bag 172.

The dust bag box 174 may be detachably coupled to the housing 110. Although not shown, a structure in which the dust bag box 174 is coupled may be formed in the interior of the housing 110 (the bag accommodating space 115), and the user may insert the dust bag box 174 into the interior of the housing 110. In addition, if the user pulls the dust bag box 174 to the outside of the cleaner base station 100 in a state where the dust bag box 174 is coupled to the cover 110, the dust bag box 174 can be separated from the cover 110. With the above configuration, the user can easily attach or detach the dust bag box 174 to or from the housing.

A dust bag 172 may be provided in the dust bag box 174. For example, at least a part of the dust bag 172 in a roll plastic form may be incorporated in the dust bag box 174, and the dust bag 172 may be inflated toward the bag supporting portion 173 in response to the operation of the dust collecting motor 191.

In addition, when the dust bag 172 is engaged with the action of the coupling 176 described later, a part of the dust bag 172 may be separated from the dust bag box 174. With the above configuration, the user does not need to additionally bind a bag or the like in which dust is trapped, and thus the user's convenience can be improved.

The dust collection portion 170 may also include a prefilter 175. The prefilter 175 may be disposed in the second flow path 182, and may separate foreign matter from air flowing through the second flow path 182. For example, the prefilter 175 may be disposed on the inlet side of the second flow path 182 to separate dust and the like contained in the air passing through the dust separation unit 171. With the above configuration, foreign matter can be prevented from flowing into the dust collection motor 191.

The dust collection portion 170 may also include an adapter 176. The adapter 176 may be disposed on the housing 110. The adapter 176 may be disposed at an upper region of the pouch support 173. The adapter 176 may sever and engage an upper region of the dust bag 172 that captures dust. Specifically, the adaptor 176 may heat-wire the upper region of the dust bag 172 by heating after focusing the upper region of the dust bag 172 at one location.

Specifically, the adapter 176 may be installed at an upper portion of the bag-receiving space 115 and a lower portion of the dust bag box 174. That is, the adapter 176 may be disposed between the bag-receiving space 115 and the dust bag box 174.

The adapter 176 may include a hotwire 1760, a moving engagement member 1761, a fixed engagement member 1762, and an engagement drive 1763.

The moving engagement member 1761 may be configured to be movable toward the fixed engagement member 1762 by receiving power from the engagement drive portion 1763. The coupling 176 may be provided with a structure for guiding the linear movement of the movable coupling member 1761.

As an example, although not shown, one or more wheels may be provided on the movable engagement member 1761.

As another example, although not shown, a guide rail may be formed on a side surface of the movable engagement member 1761. The movable engagement member 1761 may be configured to be linearly movable toward the fixed engagement member 1762 by the engagement driving portion 1763.

The hotline 1760 may be disposed on at least one of the movable engagement member 1761 and the fixed engagement member 1762.

With the above-described configuration, dust trapped in the dust tub 220 of the dust collector 200 can be collected inside the dust bag 172 of the dust collector base station 100, and the dust bag 172 can be automatically engaged. Thus, the user does not need to additionally bind a bag or the like in which dust is trapped, and thus the user's convenience can be improved.

On the other hand, although not shown, the dust collection part 170 may further include a dust amount sensor. The dust amount sensor may measure the amount of dust within the dust bag 172.

The cleaner base station 100 may include a flow path portion 180. The flow path 180 may connect the cleaner 200, the dust collection unit 170, and the dust collection motor 191.

The flow path portion 180 may include a first flow path 181, a second flow path 182, and a bypass flow path 183.

The first flow path 181 may connect the dust tub 220 of the cleaner 200 and the dust collection part 170. The first flow path 181 may be disposed at the rear side of the junction surface 121. The first flow path 181 may refer to a space between the dust tub 220 and the dust collection part 170 of the dust collector 200. The first flow path 181 may be a space formed from the dust passing hole 121a to the rear side, and may be a flow path formed from the dust passing hole 121a to the lower side and through which dust and air can flow.

For example, the first flow path 181 may include: a first region 181a communicating with the inner space of the dust tub 220 when the cleaner 200 is coupled to the cleaner base station 100 and dust is opened through the hole 121 a; and a second region 181b that communicates the first region 181a with the bag accommodating space 115 (or the inner space of the dust collecting part 170). At this time, the forming direction of the first region 181a may be configured to be substantially parallel to the axial direction (length direction) of the dust bucket. In addition, the second region 181b may be formed in a direction parallel to the longitudinal axis C of the cover 110. At this time, the first and second regions 181a and 181b may form a prescribed angle. With the above configuration, the suction force of the dust collection motor 191 can be prevented from being reduced to the maximum in the first and second flow paths 181 and 182.

Accordingly, when the dust collecting motor 191 is operated, the dust in the dust tub 220 of the dust collector 200 can flow toward the dust collecting part 170 through the first flow path 181.

The second flow path 182 may connect the dust collection part 170 and the dust suction module 190. Specifically, the second flow path 182 may be a flow path connecting an upper side of the dust collection part 170 and an upper side of the dust suction module 190. For example, the second flow path 182 may include: a third region 182a formed vertically upward from the upper side of the dust collection unit 170; a fourth region 182b connected from the third region 182a and formed in a horizontal direction; a fifth region 182c connected to the fourth region 182b and formed vertically downward; and a sixth region 182d formed in the horizontal direction from the fifth region 182c and merging with the bypass flow path 183.

With this configuration, the air having passed through the dust collection unit 170 can be guided to the dust collection motor 191 through the second flow path 182.

The bypass flow path 183 may be connected to the bag support 173 and the dust collection motor 191 in a flow path manner.

The bypass flow path 183 may communicate the bag accommodating space 115 and the inner space of the dust suction module 190. For example, the bypass flow path 183 may be a flow path formed in the gravity direction to connect the bag accommodating space 115 and the dust suction module 190. With the above configuration, the bypass flow path 183 can guide the air existing in the bag accommodating space 115 to the dust collection motor 191.

The second flow path 182 and the bypass flow path 183 may communicate with each other and be connected to the dust suction module 190. As an example, the second flow path 182 may be connected to the bypass flow path 183, and the bypass flow path 183 may be connected to the dust suction module 190. As another example, a bypass flow path 183 may be connected to the second flow path 182, and the second flow path 182 may be connected to the dust suction module 190. Thus, the second flow path 182 and the bypass flow path 183 can be connected to the dust collection unit 170 and the dust collection motor 191 in a flow path manner.

With the above configuration, the dust collecting motor 191 can be operated to hold the form of the dust bag and suck the outside air.

The cleaner base 100 may include a dust intake module 190. The dust suction module 190 may include a dust collection motor 191.

The dust collection motor 191 may be disposed at a lower portion of the dust collection part 170. The dust collection motor 191 may generate suction force to the flow path part 180. Thereby, the dust collecting motor 191 can provide suction force capable of sucking dust in the dust tub 220 of the dust collector 200.

The dust collection motor 191 may generate suction force by rotating. As an example, the dust collection motor 191 may be formed in a similar shape to a cylinder, and may generate suction force when rotating about a rotation axis. At this time, the direction of the rotation axis of the dust collection motor 191 may be arranged to be perpendicular to the ground.

Next, an operation process of the cleaner base station 100 according to the embodiment of the present invention will be described with reference to fig. 10 to 16.

First, if the cleaner 200 is coupled to the cleaner base station 100, the fixing part motor 133 is operated, whereby the dust tub 220 of the cleaner 200 can be fixed by the movement of the fixing member 131.

Thereafter, if the dust tub 220 of the cleaner 200 is fixed, the discharge cover 222 of the cleaner 200 may be opened by the operation of the cover opening motor 152, and the door 141 may open the dust passing hole 121a by the operation of the door motor 142. In this case, the inside of the dust tub 220 may communicate with the first flow path 181, the dust collection part 170.

Then, if the dust collecting motor 191 is operated, the flow path part 180 may be applied with negative pressure, and air and dust inside the dust tub 220 may flow toward the dust collecting motor 191.

Specifically, the air flowing into the first flow path 181 from the inside of the dust tub 220 may separate dust at the dust separation part 171 after passing through the first flow path 181. After that, the air in a state where dust is separated can flow to the dust collection motor 191 side through the second flow path 182 and be discharged to the outside.

On the other hand, if the bypass flow path 183 is applied with negative pressure due to the operation of the dust collecting motor 191, the dust bag 172 may expand toward the bag supporting portion 173. Thereafter, the dust separated from the air may be trapped inside the inflated dust bag 172 (refer to fig. 14).

Then, if the operation of the dust collecting motor 191 is completed, the coupling 176 may be operated. Next, a process of engaging the dust bag 172 by the adapter 176 will be specifically described.

The dust bag 172 extends downwardly from the roll of plastic (not shown) of the dust bag box 174 and through the adapter 176 to the bag support 173.

The moving engagement member 1761 may be moved by receiving power from the engagement drive 1763. The direction of movement of the moving engagement member 1761 may be a direction parallel to the ground. The moving direction of the moving engagement member 1761 may be a direction parallel to the bottom surface 111.

When the moving engagement member 1761 moves toward the fixed engagement member 1762, a portion of the dust bag 172 may be blocked in the position where the adapter 176 is disposed. (refer to FIG. 15)

The hotwire 1760 may be sealed by engaging the blocked upper portion of the dust bag 172. Dust trapped inside the sealed dust bag 172 is not discharged to the outside.

Further, the sealed dust bag 172 may be separated downward and accommodated in the bag supporting portion 173.

On the other hand, as the dust bag 172 separates, a new dust bag 172' may be created in the dust bag box 174. For example, a new dust bag 172' may be formed as the dust bag 172 separates from the roll plastic provided to the dust bag box 174 by engagement (see fig. 16).

Thereafter, the bag supporting portion 173 can be moved to the outside of the cover 110 of the cleaner base station 100. For example, a plurality of wheels 173c may be provided on the lower side of the pouch support 173, and when a user opens a side door (not shown) of the cover 110 and pulls the pouch support 173, the pouch support 173 may be moved to the outside of the cover 110. In this state, the user can take out and discard the sealed dust bag 172.

With the above-described configuration, it is possible to provide convenience in that the dust bucket can be emptied by a simple operation in which the user takes out and discards the dust bag that has been sealed from the cleaner base station 100.

On the other hand, fig. 17 shows a block diagram for explaining a control configuration in the cleaner base station of the embodiment of the present invention.

Next, a control configuration of the cleaner base station 100 according to the present invention will be described with reference to fig. 17.

The cleaner base station 100 of the embodiment of the present invention may further include a control part 300 for controlling the coupling part 120, the fixing unit 130, the door unit 140, the cover opening unit 150, the dust collecting part 170, the flow path part 180, the adapter 176, the compression driving part 178, and the dust suction module 190.

The control part 300 may be composed of a printed circuit board and elements mounted to the printed circuit board.

When the coupling sensor 125 senses the coupling of the cleaner 200, the coupling sensor 125 may transmit a signal that the cleaner 200 has been coupled to the coupling part 120. At this time, the control unit 300 may determine that the cleaner 200 is coupled to the coupling unit 120 by receiving the signal from the coupling sensor 125.

In addition, when power is supplied from the charging unit 128 to the battery 240 of the cleaner 200, the control unit 300 may determine that the cleaner 200 has been coupled to the coupling unit 120.

When it is determined that the cleaner 200 has been coupled to the coupling part 120, the control part 300 may fix the cleaner 200 by operating the fixing part motor 133.

When the fixing member 131 or the fixing portion coupler 135 moves to the prescribed fixing position FP1, the fixing sensing portion 137 may transmit a signal that the cleaner 200 has been fixed. The base station control part 300 may determine that the cleaner 200 is fixed by receiving a signal that the cleaner 200 is fixed from the fixed sensing part 137. When it is determined that the cleaner 200 is fixed, the base station control unit 300 may interrupt the operation of the fixing unit motor 133.

On the other hand, when the emptying of the dust tub 220 is completed, the control part 300 may release the fixing of the cleaner 200 by rotating the fixing part motor 133 in the opposite direction.

When it is determined that the cleaner 200 is fixed to the coupling part 120, the control part 300 may open the door 141 of the cleaner base station 100 by operating the door motor 142.

When the door 141 or the door arm 143 reaches the prescribed open position DP1, the door opening/closing sensing portion 144 may transmit a signal that the door 141 has been opened. The control part 300 may determine that the door 141 has been opened by receiving a signal that the door 141 has been opened from the door opening/closing sensing part 137. When it is determined that the door 141 has been opened, the control part 300 may interrupt the operation of the door motor 142.

On the other hand, when the emptying of the dust tub 220 is completed, the control part 300 may close the door 141 by rotating the door motor 142 in the opposite direction.

When it is determined that the door 141 has been opened, the control part 300 may open the discharge cover 222 of the cleaner 200 by operating the cover opening motor 152.

When the guide frame 151e reaches the prescribed open position CP1, the cover opening sensing part 155f may transmit a signal that the discharge cover 222 has been opened. The control part 300 may determine that the discharge cap 222 has been opened by receiving a signal that the discharge cap 222 has been opened from the cap opening sensing part 155 f. When it is determined that the discharge cap 222 has been opened, the control part 300 may interrupt the operation of the cap opening motor 152.

On the other hand, in the present embodiment, the control section 300 may operate the coupling 176 after the operation of the dust collecting motor 191 is completed. As an example, the control unit 300 may operate the adapter 176 when a predetermined time period set in advance has elapsed after the operation of the dust collection motor 191 is completed. As another example, the control unit 300 may operate the adapter 176 when a predetermined time elapses after the dust collection motor 191 is operated a predetermined number of times. As another example, the control unit 300 may operate the adapter 176 every predetermined cycle, and operate the adapter 176 when a predetermined time elapses while the dust collection motor 191 is operating. In addition, the control unit 300 may operate the adapter 176 when the amount of dust measured by the dust amount sensor (not shown) exceeds a predetermined reference.

Specifically, the control unit 300 may move the movable engagement member 1761 toward the fixed engagement member 1762 by operating the engagement driving unit 1763, thereby closing the dust bag 172, and may thermally wire-engage the dust bag 172 by operating the hot wire 1760.

With the above configuration, the dust bag 172 can be sealed in a state where dust is settled into the dust bag 172 instead of floating in the inside of the cleaner base station 100, and hygiene can be improved.

The control part 300 may suck the dust inside the dust tub 220 by driving the dust collecting motor 191.

On the other hand, the control part 300 can move the bag compressing member 177 by driving the compression driving part 178, thereby discharging air of the dust bag 172 and compressing, so that the volume of the dust bag 172 can be reduced. The specific compression process of the dust bag 172 by the compression drive section 178 will be described in more detail below with other figures.

The control part 300 may display the dust bucket empty status and the charging status for the dust collector 200 by operating the display part 310. For example, in the present embodiment, in the case where the amount of dust measured by the dust amount sensor exceeds a prescribed reference value, the control section 300 may display on the display section 310 the content regarding the need to replace the dust bag 172.

On the other hand, the cleaner base station 100 of the present invention may include a display part 310.

The display unit 310 may be provided not only in the cover 110 but also in an additional display device and may be provided in a terminal including a mobile phone.

The display unit 310 may be configured to include at least one of a display panel capable of outputting text and/or graphics and a speaker capable of outputting a voice signal and sound. By the information output from the display unit, the user can easily grasp the current process status, remaining time, and the like.

In another aspect, the cleaner base station 100 of an embodiment of the present invention can include a memory 330. The memory 330 may contain various data for the driving and operation of the cleaner base station 100.

On the other hand, the cleaner base station 100 of the embodiment of the present invention may include an input 340. The input unit 340 generates key input data that is input by a user to control the operation of the cleaner base station 100. For this, the input part 340 may be constituted by a keyboard (key pad), a dome switch (dome switch), a touch pad (static pressure/static electricity), or the like. In particular, in the case where the touch panel and the display portion 310 form a layered structure, it may be referred to as a touch screen (touch screen).

Fig. 18 and 19 show diagrams for explaining a biaxial movement joint of a cleaner base station according to an embodiment of the present invention.

Next, the structure of the biaxial movement joint of the vacuum cleaner base station according to the embodiment of the present invention will be described with reference to fig. 18 and 19.

An adaptor 176 may be installed at an upper portion of the bag receiving space 115. Specifically, the adapter 176 may be installed at an upper portion of the bag-receiving space 115 and a lower portion of the dust bag box 174. That is, the adapter 176 may be disposed between the bag-receiving space 115 and the dust bag box 174.

The movable engagement member 1761 may be comprised of a first movable engagement member 1761a and a second movable engagement member 1761 b. The engagement driving portion 1763 may be composed of a first engagement driving portion 1763a and a second engagement driving portion 1763 b. The first movable engagement member 1761a is movable in a first direction by the first engagement driving portion 1763a, and the second movable engagement member 1761b is movable in a second direction perpendicular to the first direction by the second engagement driving portion 1763 b. The first direction and the second direction may be parallel to the ground. The first direction and the second direction may be parallel to the bottom surface 111.

The first and second movable engagement members 1761a and 1761b may be linearly movable in a sliding manner. As an example, as shown in fig. 18 and 19, a rail for linearly moving the movable engagement member 1761 may be formed at an upper portion of the engagement 176. The first and second movable engagement members 1761a, 1761b may move linearly along the track.

As another example, although not shown, a wheel for linear movement may be provided to the movement engagement member 1761.

The first engagement driving portion 1763a may include a motor (not shown) for sliding the first movable engagement member 1761a, and the second engagement driving portion 1763b may include a motor (not shown) for sliding the second movable engagement member 1761 b.

Next, a dust bag 172 coupling process of the dual shaft mobile coupling of the cleaner base station according to the embodiment of the present invention will be described with reference to fig. 18 and 19.

The control portion 300 may engage the dust bag 172 by actuating the engagement 176.

Specifically, the control unit 300 may move the first movable engagement member 1761a in a first direction by operating the first movable engagement member 1761a, and the control unit 300 may move the second movable engagement member 1761b in a second direction perpendicular to the first direction by operating the second movable engagement member 1761 b.

If the dust bag 172 is blocked by the movement of the first and second moving engagement members 1761a and 1761b, the control portion 300 may engage the upper portion of the dust bag 172 by operating the hot wire 1760.

Thus, when the dust bag 172 is plugged and joined by providing the plurality of moving joint members 1761, there is an advantage in that the dust bag 172 can be more effectively sealed and joined and the dust scattering preventing effect can be improved, as compared with the embodiment in which one moving joint member 1761 is provided.

After the closing and engagement of the dust bag 172 is completed, the first movable engagement member 1761a may be moved away from the fixed engagement member 1762 by the first engagement drive 1763a, and the second movable engagement member 1762b may be moved away from the fixed engagement member 1762 by the second engagement drive 1763 b. That is, after the closing and engagement of the dust bag 172 is completed, the movable engagement member 1761 may return to its original position.

After the moving engagement member 1761 returns to its original position, a new dust bag 172' may be deployed to the bag-receiving space 115.

Fig. 20 to 27 are views for explaining an adapter 176 and a bag compressing member 177 of a cleaner base station according to an embodiment of the present invention.

Next, with reference to fig. 20 to 23, the adaptor 176 and the bag compressing member 177 of the cleaner base station 100 according to an embodiment of the present invention will be described.

The bag-accommodating space 115 may be provided with a bag compression member 177 and a compression driving portion 178. In the present embodiment, the bag compressing member 177 may include a flow path blocking member 177a. The flow path blocking member 177a is movably coupled to the bag accommodating space 115 and is provided to be able to open or block the bypass flow path 183.

The flow path blocking member 177a may be disposed at a lower portion of the bag accommodating space 115.

As an example, the flow path blocking member 177a may be coupled to the lower portion of the bag accommodating space 115 so as to be linearly movable in a sliding manner (see fig. 20 and 21). The bag compressing member 177 may be provided with a rail or a wheel for guiding the linear movement of the flow path blocking member 177 a.

As another example, the flow path blocking member 177a may be provided to be hinge-coupled at a lower portion of the bag accommodating space 115 so as to be rotatably movable (refer to fig. 22 and 23). The bag compressing member 177 may be provided with a hinge structure for rotational movement of the flow path blocking member 177 a.

The compression driving portion 178 is provided to be connected to the flow path blocking member 177a and is capable of moving the flow path blocking member 177 a. The compression driving part 178 may include a flow path blocking motor 178a for linearly moving or rotationally moving the flow path blocking member 177 a.

The flow path blocking member 177a may be formed in a shape similar to a disc. A gasket (not shown) made of silicon or the like may be disposed on the top surface of the flow path blocking member 177a to effectively block the bypass flow path 183.

On the other hand, the adapter 176 may have a movable engagement member 1761 and a fixed engagement member 1762, with the movable engagement member 1761 being movable toward the fixed engagement member 1762.

When the dust bag 172 needs to be emptied, the control unit 300 may control the engagement driving unit 1763 to stop the movement of the movable engagement member 1761 at a predetermined distance from the fixed engagement member 1762. Thus, the upper portion of the dust bag 172 is not completely sealed, and thus an air flow path through which air inside the dust bag can be discharged can be formed. In this case, the air flow path is preferably arranged near the dust separating unit 171.

Specifically, when the fixed engagement member 1762 is disposed directly under the dust separation portion 171 and the moving engagement member 1761 stops moving in a state of being spaced apart from the fixed engagement member 1762 by a predetermined distance, the air flow path at the upper portion of the dust bag 172 may be disposed directly under the dust separation portion 171.

Then, the flow path blocking member 177a can be linearly moved or rotationally moved by the flow path blocking motor 178a, thereby blocking the bypass flow path 183. The control unit 300 may operate the dust collection motor 191 after the bypass passage 183 is blocked.

When the dust collection motor 191 is operated, the first and second flow paths 181 and 182 are applied with negative pressure. The air inside the dust bag 172 may be discharged to the dust separating part 171 by the negative pressure formed in the second flow path 182.

On the other hand, since the bypass flow path 183 is blocked, the negative pressure is not applied to the bypass flow path 183, and the dust bag 172 does not expand.

Therefore, by operating the dust collection motor 191 in a state where the bypass flow path 183 is blocked by the flow path blocking member 177a, it is possible to discharge air inside the dust bag 172 and compress the dust bag 172, minimizing the volume of the dust bag 172.

After the compression of the dust bag 172 is completed, the control unit 300 may move the flow path blocking member 177a linearly or rotationally by the flow path blocking motor 178a, thereby opening the bypass flow path 183 again.

Next, with reference to fig. 24 to 27, an adapter 176 and a bag compressing member 177 of a cleaner base station 100 according to another embodiment of the present invention will be described.

The bag-accommodating space 115 may be provided with a bag compression member 177 and a compression driving portion 178. In this embodiment, the bag compressing member 177 may include a pressing member 177b that applies pressure to the outer surface of the dust bag 172. The pressing member 177b is coupled to be movable inside the bag supporting portion 173 and is provided to be capable of pressing the dust bag 172. The pressing member 177b may be formed in a rectangular flat plate shape.

The pressing member 177b may be disposed inside the pouch support 173.

As an example, the pressing member 177b may be coupled to be linearly movable in a sliding manner inside the bag supporting portion 173 (see fig. 24 and 25). A rail or a wheel guiding the rectilinear movement of the pressing member 177b may be provided at the bag compressing member 177.

As another example, the pressing member 177b may be provided to be capable of rotational movement inside the pouch support 173 by hinge coupling (refer to fig. 26 and 27). A hinge structure for rotational movement of the pressing member 177b may be provided at the bag compressing member 177.

The compression driving portion 178 is provided to be connected to the flow path blocking member 177a and is capable of moving the flow path blocking member 177 a. The compression driving part 178 may include a compression motor 178b for linearly moving or rotationally moving the compression member 177 b.

As described above, the control unit 300 may control the engagement driving unit 1763 to stop the movement of the movable engagement member 1761 at a predetermined distance from the fixed engagement member 1762, so that the upper portion of the dust bag 172 is not completely closed, and an air flow path is formed. Preferably, the air flow path formed in the dust bag 172 is disposed immediately below the dust separating part 171.

Then, pressure may be applied to the outer surface of the dust bag 172 by the pressing member 177b moving straight or rotating. The air inside the dust bag 172 can be discharged by the pressure applied by the pressing member 177 b.

The pressing member 177b provided to be linearly movable is linearly movable from one side to the other side of the inner wall of the pouch support 173. Preferably, the direction of the linear movement of the pressing member 177b is parallel to the direction of the movement of the movable engagement member 1761 toward the fixed engagement member 1762.

From a different point of view, it is preferable that the other side is under the fixed engagement member 1762. That is, the pressing member 177b is preferably moved to compress the dust bag 172 downward of the air flow path formed by the fixed engagement member 1762 and the moving engagement member 1761 above the dust bag 172, so that the air inside the dust bag 172 can be preferably discharged to the air flow path.

The pressing member 177b rotatably provided may be rotatably coupled by being hinged at its lower end to a lower end of one side of the inner wall of the pouch support 173.

Specifically, the pressing member 177b rotatably provided may be disposed parallel to one side of the inner wall of the bag supporting portion 173 and perpendicular to the bottom of the bag supporting portion 173.

The pressing motor 178b may rotate the pressing member 177b to form a predetermined angle with one side of the inner wall of the pouch support 173. From a different perspective, the pressing motor 178b may rotate the pressing member 177b from a state perpendicular to the bottom of the pouch support 173 to form an acute angle (gradually facing the bottom of the pouch support 173).

By the above-described rotational movement, the pressing member 177b may press the dust bag 172 from the top down, and the air inside the dust bag 172 may be discharged through the upper air flow path.

After the compression of the dust bag 172 is completed, the pressing motor 178b linearly or rotatably moves the pressing member 177b to the original position, whereby a space for a new dust bag 172' to extend downward from the roll plastic (not shown) and pass through the adapter 176 into the bag supporting portion 173 can be formed again.

After the dust bag 172 is compressed by the bag compressing member 177, the adaptor 176 may close the upper end of the dust bag 172 by further moving the moving engaging member 1761 toward the fixed engaging member 1762, and then heat-wire-engage the upper end of the dust bag 172 by operating the heat wire 1760, thereby sealing the dust bag 172.

With the above-described configuration, the dust bag 172 can be sealed in a state where the volume thereof is significantly reduced, and convenience and hygiene in taking out the sealed dust bag 172 from the bag supporting portion 173 to the outside and discarding the same can be improved.

Fig. 28 and 29 are flowcharts for explaining a process of reducing the volume of the dust bag 172 by compressing the dust bag 172 inside the dust collecting part 170 of the cleaner base station 100, and sealing by engagement according to an embodiment of the present invention.

Next, with reference to fig. 20 to 29, a process of compressing the dust bag 172 inside the dust collecting part 170 by the cleaner base station 100 of the embodiment of the present invention to reduce the volume of the dust bag 172 and sealing the dust bag 172 by bonding will be described.

After the connection of the cleaner 200, the control unit 300 of the cleaner base station 100 of the present invention can trap dust inside the dust tub 220 into the dust bag 172 inside the cleaner base station 100 by driving the dust collecting motor 191 (S10).

After trapping dust to the dust bag 172, if the user instructs the input part 340 to pack the dust bag 172, the input part 340 may transmit a dust bag 172 pack signal to the control part 300 (S20).

The control part 300 receiving the packing signal may tighten the inlet of the dust bag by operating the engagement driving part 1763 (S30).

The engagement drive portion 1763 may include a first engagement drive portion 1763a and a second engagement drive portion 1763b. The first engagement driving portion 1763a may move the first movable engagement member 1761a, and the second engagement driving portion 1763b may move the second movable engagement member 1761 b.

Specifically, the control unit 300 may move the first movable engagement member 1761a in a first direction by operating the first engagement driving unit 1763a, and may move the second movable engagement member 1761b in a second direction perpendicular to the first direction by operating the second engagement driving unit 1763 b.

At this time, the moving direction of the first and second moving engagement members 1761a and 1761b may be toward the fixed engagement member 1762. The first and second movable engagement members 1761a and 1761b stop at a predetermined distance from the fixed engagement member 1762, and thus the inlet of the dust bag 172 can be restricted to a predetermined width to tighten the inlet of the dust bag 172.

After the inlet of the dust bag 172 is tightened, the control part 300 may move the bag compressing member 177 by operating the compression driving part 178, thereby compressing the dust bag (S40).

The bag compressing member 177 may include a flow path blocking member 177a or a pressing member 177b. The compression driving part 178 may include a flow path blocking motor 178a capable of moving the flow path blocking member 177a or a pressing motor 178b capable of moving the pressing member 177b.

As an example, after tightening the inlet of the dust bag 172, the control unit 300 may move the flow path blocking member 177a by operating the flow path blocking motor 178a, thereby blocking the bypass flow path 183 connecting the bag accommodating space 115 and the dust collecting motor 191 (S41 a).

After that, the control part 300 can discharge the air inside the dust bag 172 by driving the dust collecting motor 191 in a state where the bypass flow path 183 is blocked, and reduce the volume by compressing the dust bag 172 (S41 b) (steps S41a and S41b belong to step S40).

As another example, after tightening the inlet of the dust bag 172, the control part 300 may move the pressing member 177b by operating the pressing motor 178b, thereby discharging air inside the dust bag 172 by pressing the outer surface of the dust bag 172 and reducing the volume by compressing the dust bag 172. The movement of the pressing member 177b may be a linear movement or a rotational movement (S42) (step S42 belongs to step S40).

The control part 300 may heat-wire-bond the dust bag 172 by driving the bonder 176 after compressing the dust bag 172 to achieve sealing (S50).

Specifically, the control unit 300 can move the first movable engagement member 1761a to the maximum extent in the first direction (S51) and move the second movable engagement member 1761b to the maximum extent in the second direction (S52) by operating the first engagement driving unit 1763a and the second engagement driving unit 1763b, thereby closing the upper portion of the dust bag 172. Thereafter, the control unit 300 may thermally bond the upper portion of the dust bag 172 by operating the hot wire 1760, thereby sealing the dust bag 172.

As another example, even if there is no input of the user' S dust bag 172 package (the bag package signal receiving step (step S20) is omitted), the dust bag may be compressed and sealed by operating the compression driving part 178 and the engagement driving part 1763 in the aforementioned manner when a predetermined time period has elapsed after the operation of the dust collecting motor 191 is completed.

As yet another example, the control unit 300 may compress and seal the dust bag by operating the compression driving unit 178 and the engagement driving unit 1763 in the aforementioned manner when a predetermined time elapses after the dust collecting motor 191 is operated a predetermined number of times.

As yet another example, the control unit 300 may operate the compression driving unit 178 and the engagement driving unit 1763 at every predetermined cycle, and compress and seal the dust bag by operating the engagement driving unit 1763 after a predetermined time elapses while the dust collecting motor 191 is operating.

In addition, the control unit 300 may compress and seal the dust bag by operating the compression driving unit 178 and the engagement driving unit 1763 when the amount of dust measured by the dust amount sensor (not shown) exceeds a predetermined reference.

According to the different embodiments as described above, even in the case where the user forgets or cannot pay attention to empty the dust bag 172, the dust bag 172 is compressed and sealed at an appropriate timing, so that dust can be prevented from scattering and hygiene can be maintained.

While the present invention has been described in detail by way of specific examples, the above description is only for specific explanation of the present invention, and the present invention is not limited thereto, and it will be apparent to those skilled in the art that modifications and improvements can be made thereto without departing from the scope of the technical spirit of the present invention.

The invention is simply modified to be modified within the scope of the invention, and the specific protection scope of the invention is more apparent from the appended claims.
