Description

Technical Field

[0001] The present invention relates to a vacuum cleaner base station, and more particularly, to a vacuum cleaner base station capable of closing a discharge cover of a vacuum cleaner with a simple structure. Background Art

[0002] In general, a vacuum cleaner is a household appliance that uses electricity to suck in air to suck in small garbage or dust and fills the dust collection bucket located inside the product. It is usually called a vacuum cleaner.

[0003] Vacuum cleaners can be divided into manual vacuum cleaners that the user moves while cleaning, and automatic vacuum cleaners that move and clean autonomously. Depending on the specifications of the vacuum cleaner, manual vacuum cleaners can be divided into canister vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick vacuum cleaners.

[0004] Household vacuum cleaners used to be mostly canister vacuum cleaners, but recently there has been a trend towards using handheld vacuum cleaners and stick vacuum cleaners that have improved usability by integrating a dust collecting bucket with the cleaner body.

[0005] The main body and the suction port of the horizontal vacuum cleaner are connected by a rubber tube or a hose, and the brush can be inserted into the suction port for use according to the situation.

[0006] Handheld vacuum cleaners maximize portability. While lightweight, they are short, requiring a seated position, limiting the area they can clean. Therefore, they are typically used for cleaning small areas, such as desks, sofas, and cars.

[0007] Stick vacuums can be used while standing, allowing for cleaning without bending over. This makes them ideal for sweeping over wide areas. While handheld vacuums are used to clean narrow spaces, stick vacuums can be used to clean wider areas, reaching high places that are difficult to reach. Recently, stick vacuums have become available in modular configurations, allowing users to automatically change the type of cleaner to suit a variety of needs.

[0008] However, the dust collecting bucket for storing collected dust in existing handheld vacuum cleaners and stick vacuum cleaners has a small capacity, so that the user has to empty the dust collecting bucket every time.

[0009] Furthermore, when the dust collecting bucket is emptied, dust is scattered, which poses a risk to the health of the user.

[0010] Furthermore, when the residual dust in the dust collecting bucket cannot be removed, there is a problem of reducing the suction power of the vacuum cleaner.

[0011] Furthermore, when the residual dust in the dust collecting container is not removed, there is a problem of foul odor caused by the residual dust.

[0012] As an existing patent document, Korean Patent Publication No. 10-2022-0086482 discloses a vacuum cleaner base station that can automatically empty the dust collection bucket of the vacuum cleaner when the vacuum cleaner is combined.

[0013] The aforementioned prior art patent document discloses a technology for automatically opening and closing the dust bin's discharge lid using a door unit. However, this technology presents the following issues: the door unit requires a door motor to drive the door, and to accurately rotate the connecting rod, an encoder and other components are also required to sense the rotation of the motor shaft. This increases the number of components and costs.

[0014] Furthermore, in the case of a door unit, if a door motor fails when the door is in a position where the dust through hole is opened, the user needs to personally close the discharge cover of the dust collecting bucket, which is harmful to the user's health and causes inconvenience to the user.

[0015] In addition, in the case of a door unit, if a door motor fails when the door is in a position to close the dust passage hole, there is a problem that the door cannot be opened and the dust in the dust collecting bucket of the vacuum cleaner cannot be sucked in at the base station. Summary of the Invention

[0016] Technical problems to be solved

[0017] The present invention is made to improve the problems of the existing vacuum cleaner base station, vacuum cleaner system and control method thereof as described above, and its object is to provide a vacuum cleaner base station with a simple structure and construction.

[0022] The cover control unit may include a long hole, and when the button moves linearly, the long hole is arranged in a direction perpendicular to the direction in which the button moves, and the connecting rod includes a connecting protrusion inserted into the long hole and moving along the long hole.

[0023] The connecting rod may include: a first connecting rod having the connecting protrusion so as to rotate when the button moves linearly; and a second connecting rod rotatably coupled to the first connecting rod and rotatably coupled to the cover control frame.

[0024] The characteristic is that the above-mentioned shell can have an elastic body support part arranged opposite to the lower end of the above-mentioned button, and the two ends of the above-mentioned elastomer are respectively fixed to the lower end of the above-mentioned button and the above-mentioned elastic body support part and arranged along the direction of linear motion of the above-mentioned button.

[0025] The elastic body may be provided in plurality.

[0026] The cover control unit may further include a guide pin disposed inside the elastic body, with one end portion fixed to the button and the other end portion penetrating the elastic body support portion.

[0027] The characteristic feature is that the elastic body is provided in a pre-compressed state.

[0037] The vacuum cleaner base station according to the present invention as described above has one or more of the following effects.

[0038] According to the present invention, it is possible to relieve the user from the trouble of emptying the dust container every time.

[0039] Furthermore, the user does not need to open the discharge cover before attaching the vacuum cleaner to the vacuum cleaner base station. After the dust collection motor has finished operating, the user can manually close the discharge cover while the vacuum cleaner is attached to the vacuum cleaner base station. This eliminates the need for the user to manually open and close the discharge cover in the dust collection bucket, preventing dust from scattering during this process.

[0040] Furthermore, the lid control unit for closing the discharge lid does not include a motor, thereby reducing the number of components, reducing weight, and preventing noise generated by the motor. Furthermore, the absence of components for controlling the motor, encoders for precise motor control, and sensors for position sensing reduces the number of components and simplifies the structure.

[0041] Furthermore, the invention has the effect of solving the following problems: in the existing structure in which a motor is used to start a cover to control a frame, when a motor fails, it causes inconvenience to the user or dust collection cannot be performed.

[0042] Furthermore, the dust collecting motor can be started while the discharge cover is opened after the vacuum cleaner is combined, thereby having the effect of reducing the time required for the dust collecting bucket to collect the dust. In addition, the time required for fixing or unfixing the vacuum cleaner is reduced, thereby having the effect of reducing the entire working time.

[0043] The effects of the present invention are not limited to the effects described above, and those skilled in the art can easily understand other effects not described based on the contents described in the claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0056] The present invention is susceptible to numerous modifications and various embodiments. Specific embodiments are shown in the accompanying drawings and detailed descriptions are given. This is not intended to limit the present invention to specific embodiments, but should be construed as encompassing all modifications, equivalents, and substitutes within the spirit and technical scope of the present invention.

[0057] Hereinafter, the present invention will be described through multiple embodiments of the present invention with reference to the accompanying drawings for illustrating a vacuum cleaner base station.

[0058] Figure 1 is a three-dimensional diagram of a vacuum cleaner system consisting of a vacuum cleaner base station and a vacuum cleaner according to an embodiment of the present invention, Figure 5 FIG. 1 is a schematic diagram of a vacuum cleaner system according to an embodiment of the present invention.

[0059] Reference Figure 1 as well as Figure 5 According to an embodiment of the present specification, a vacuum cleaner system 10 may include a vacuum cleaner base station 100 and a vacuum cleaner 200 .

[0060] The vacuum cleaner system 10 may include a vacuum cleaner base station 100. The vacuum cleaner 200 may be coupled to the vacuum cleaner base station 100. Specifically, the main body of the vacuum cleaner 200 may be coupled to the side of the vacuum cleaner base station 100. The vacuum cleaner base station 100 may remove dust from the dust collection bucket 220 of the vacuum cleaner 200.

[0061] on the other hand, Figure 2 as well as Figure 3 A diagram for explaining a vacuum cleaner in a vacuum cleaner system according to an embodiment of the present invention is shown. Figure 4 A diagram illustrating the lower side of a dust collecting bucket of a vacuum cleaner according to an embodiment of the present invention is shown.

[0062] First, refer to the following Figures 1 to 5 The structure of the vacuum cleaner 200 will be described.

[0063] The vacuum cleaner 200 may be a vacuum cleaner that is manually operated by a user. For example, the vacuum cleaner 200 may be a handheld vacuum cleaner or a stick vacuum cleaner.

[0064] The vacuum cleaner 200 can be placed on the vacuum cleaner base station 100. The vacuum cleaner 200 can be supported by the vacuum cleaner base station 100. The vacuum cleaner 200 can be combined with the vacuum cleaner base station 100.

[0065] On the other hand, in one embodiment of the present invention, the direction of the vacuum cleaner 200 can be defined based on the situation where the dust collecting bucket 220 and the lower side of the battery housing 230 are placed on the ground.

[0066] In this case, the front may refer to the direction in which the suction unit 212 is disposed relative to the suction motor 214, and the rear may refer to the direction in which the handle 216 is disposed relative to the suction motor 214. Furthermore, when viewing the suction unit 212 from the suction motor 214, the direction disposed on the right side may be referred to as the right side, and the direction disposed on the left side may be referred to as the left side. Furthermore, in one embodiment of the present invention, the upper side and the lower side may be defined perpendicular to the ground, based on the lower side of the dust collecting bucket 220 and the battery housing 230 being placed on the ground.

[0067] The cleaner 200 may include a main body 210 , which may include a main body housing 211 , a suction unit 212 , a dust separation unit 213 , a suction motor 214 , an exhaust cover 215 , a handle 216 , and an operation unit 218 .

[0068] The main housing 211 may constitute the exterior of the vacuum cleaner 200. The main housing 211 may provide a space for accommodating the suction motor 214 and a filter (not shown) therein. The main housing 211 may be configured in a cylindrical shape.

[0069] The suction portion 212 may protrude outward from the main housing 211. For example, the suction portion 212 may be formed in a cylindrical shape with an open interior. The suction portion 212 may be coupled to the extension tube 250. The suction portion 212 may provide a flow path (hereinafter sometimes referred to as a "suction flow path") through which air including dust can flow.

[0070] On the other hand, in this embodiment, a virtual line may be formed that passes through the interior of the suction portion 212 configured in a cylindrical shape.

[0071] The dust separation unit 213 may be in communication with the suction unit 212. The dust separation unit 213 may separate the dust sucked into the interior through the suction unit 212. The space inside the dust separation unit 213 may be in communication with the space inside the dust collecting bucket 220.

[0072] For example, the dust separator 213 may include at least one cyclone unit that can separate dust using a swirling flow. Furthermore, the space inside the dust separator 213 may be connected to the intake flow path. Therefore, air and dust drawn in through the intake unit 212 can flow in a spiral along the inner circumferential surface of the dust separator 213. Thus, a swirling flow can be generated within the interior space of the dust separator 213.

[0073] The dust separator 213 is communicated with the suction unit 212 , and has a structure that applies the principle of a dust collector using centrifugal force in order to separate dust sucked into the main body 210 through the suction unit 212 .

[0074] The dust separator 213 may further include a secondary cyclone for further separating dust from the air discharged from the cyclone. In this case, the secondary cyclone may be located inside the cyclone to minimize the size of the dust separator. The secondary cyclone may include multiple cyclone bodies arranged in parallel. The air discharged from the cyclone may be divided into multiple cyclone bodies for passage.

[0075] At this time, the axis of the cyclone flow of the secondary cyclone can also extend in the vertical direction, and the axis of the cyclone flow of the cyclone and the axis of the cyclone flow of the secondary cyclone can be formed coaxially in the vertical direction, which can be collectively referred to as the axis of the cyclone flow of the dust separation part 213.

[0076] The suction motor 214 can generate suction for inhaling air. The suction motor 214 can be housed in the main body housing 211. The suction motor 214 can generate suction by rotating. As an example, the suction motor 214 can be formed in a shape similar to a cylinder.

[0077] On the other hand, in this embodiment, a virtual suction motor axis extending the rotation axis of the suction motor 214 may be formed.

[0078] The exhaust cover 215 may be disposed on one side in the axial direction of the main housing 211. A filter for filtering air may be housed in the exhaust cover 215. For example, a high efficiency (HEPA) filter may be housed in the exhaust cover 215.

[0079] An exhaust port for exhausting air sucked in by the suction force of the suction motor 214 may be formed in the exhaust cover 215 .

[0080] A flow guide may be provided at the exhaust cover 215. The flow guide may guide the flow of air exhausted through the exhaust port.

[0081] The handle 216 can be gripped by the user. The handle 216 can be arranged behind the suction motor 214. As an example, the handle 216 can be formed in a cylindrical shape. Alternatively, the handle 216 can be formed in a curved cylindrical shape. The handle 216 is arranged to form a predetermined angle with respect to the main housing 211, the suction motor 214, or the dust separator 213.

[0082] The handle 216 may include a holding portion formed in a columnar shape for the user to hold, a first extension portion connected to one end portion of the holding portion in the longitudinal direction (axial direction) and extending toward the suction motor 214, and a second extension portion connected to the other end portion of the holding portion in the longitudinal direction (axial direction) and extending toward the dust collecting container 220.

[0083] On the other hand, in this embodiment, a virtual grip portion penetration line extending in the longitudinal direction of the grip portion (the axial direction of the column) and penetrating the grip portion may be formed.

[0084] As an example, the grip portion penetration line may be a virtual line formed inside the cylindrical handle 216 or a virtual line formed parallel to at least a portion of the outer side surface (outer peripheral surface) of the grip portion.

[0085] The upper surface of the handle 216 may form a partial appearance of the upper surface of the cleaner 200. Thus, when the user holds the handle 216, a structure of the cleaner 200 is prevented from contacting the user's arm.

[0086] The first extension portion may extend from the grip portion toward the main body housing 211 or the suction motor 214. At least a portion of the first extension portion may extend in a horizontal direction.

[0087] The second extension portion may extend from the handle 216 toward the dust container 220. At least a portion of the second extension portion may extend in a horizontal direction.

[0088] The operating unit 218 may be provided on the handle 216. The operating unit 218 may be provided on an inclined surface formed on an upper region of the handle 216. The user may input an operation or stop command for the cleaner 200 through the operating unit 218.

[0089] The cleaner 200 may include a dust collecting bucket 220. The dust collecting bucket 220 may be in communication with the dust separating portion 213. The dust collecting bucket 220 may store dust separated from the dust separating portion 213.

[0090] The dust collecting bucket 220 may include a dust collecting bucket body 221 , a discharge cover 222 , a dust collecting bucket compression rod 223 , and a compression member (not shown).

[0091] The dust collecting container body 221 may provide a space capable of storing the dust separated by the dust separating portion 213. As an example, the dust collecting container body 221 may be formed in a cylindrical shape.

[0092] On the other hand, in this embodiment, a virtual dust bucket penetration line can be formed that passes through the interior (internal space) of the dust bucket body 221 and extends along the length direction of the dust bucket body 221 (referring to the axial direction of the cylindrical dust bucket body 221).

[0093] A portion of the lower side (bottom surface) of the dust collecting bucket body 221 can be opened. In addition, a lower extension portion 221a can be formed on the lower side (bottom surface) of the dust collecting bucket body 221. The lower extension portion 221a can be formed to block a portion of the lower side of the dust collecting bucket body 221.

[0094] The dust collecting bucket 220 may include a discharge cover 222. The discharge cover 222 may be configured on the lower side of the dust collecting bucket 220.

[0095] The discharge cover 222 can be set to open and close the end portion of one side of the length direction of the dust collecting bucket body 221. Specifically, the discharge cover 222 can selectively open and close the lower part of the dust collecting bucket 220 that opens downward.

[0096] The discharge cover 222 may include a cover body 222a and a hinge portion 222b. The cover body 222a may be formed to block a portion of the lower side of the dust collecting bucket body 221. The cover body 222a may rotate downward with the hinge portion 222b as a reference. The hinge portion 222b may be arranged adjacent to the battery housing 230. A torque spring 222d may be provided at the hinge portion 222b. Therefore, when the discharge cover 222 is separated from the dust collecting bucket body 221, the cover body 222a is supported in a state of rotating above a predetermined angle with the hinge portion 222b as an axis by the elastic force of the torque spring 222d.

[0097] The discharge cover 222 can be coupled to the dust collection bucket 220 via a hook. Alternatively, the discharge cover 222 can be detached from the dust collection bucket 220 via a coupling rod 222c. The coupling rod 222c can be positioned in front of the dust collection bucket. Specifically, the coupling rod 222c can be positioned on the front outer side of the dust collection bucket 220. When an external force is applied, the coupling rod 222c elastically deforms a hook extending from the cover body 222a, thereby releasing the coupling between the cover body 222a and the dust collection bucket body 221.

[0098] When the discharge cover 222 is closed, the lower side of the dust collecting container 220 can be blocked (sealed) by the discharge cover 222 and the lower extending portion 221 a .

[0099] The dust collecting bucket 220 may include a dust collecting bucket compression rod 223 (see Figure 3). The dust bucket compression rod 223 can be configured on the outside of the dust bucket 220 or the dust separation part 213. The dust bucket compression rod 223 can be configured on the outside of the dust bucket 220 or the dust separation part 213 in a manner that can move up and down. The dust bucket compression rod 223 can be connected to a compression member (not shown). In the case that the dust bucket compression rod 223 moves downward due to external force, the compression member (not shown) can also move downward together. Thereby, user convenience can be provided. The compression member (not shown) and the dust bucket compression rod 223 can return to their original positions by an elastic member (not shown). Specifically, when the external force applied to the dust bucket compression rod 223 is released, the elastic member can cause the dust bucket compression rod 223 and the compression member (not shown) to move upward.

[0100] A compression member (not shown) can be arranged inside the dust bucket body 221. The compression member can move in the internal space of the dust bucket body 221. Specifically, the compression member can move up and down inside the dust bucket body 221. Thus, the compression member can compress the dust inside the dust bucket body 221 downward. Moreover, when the discharge cover 222 is separated from the dust bucket body 221 and the lower part of the dust bucket 220 is opened, the compression member moves from the upper part of the dust bucket 220 to the lower part, and impurities such as residual dust in the dust bucket 220 can be removed. Thus, residual dust is avoided from remaining in the dust bucket 220, thereby improving the suction power of the vacuum cleaner. Moreover, residual dust is avoided from remaining in the dust bucket 220, thereby removing the odor caused by the residue.

[0101] The vacuum cleaner 200 may include a battery housing 230. The battery housing 230 may house a battery 240. The battery housing 230 may be disposed below the handle 216. For example, the battery housing 230 may be in the shape of a hexahedron with an open lower portion. The back of the battery housing 230 may be connected to the handle 216.

[0102] The battery case 230 may include a housing portion open downward, and the battery 240 may be installed and removed through the housing portion of the battery case 230 .

[0103] The cleaner 200 may include a battery 240 .

[0104] For example, the battery 240 can be detachably coupled to the vacuum cleaner 200. The battery 240 can be detachably coupled to the battery housing 230. As an example, the battery 240 can be inserted from the bottom of the battery housing 230 into the interior of the battery housing 230. This structure can improve the portability of the vacuum cleaner 200.

[0105] Alternatively, the battery 240 may be integrally provided inside the battery housing 230. In this case, the lower surface of the battery 240 is not exposed to the outside.

[0106] The battery 240 can supply power to the suction motor 214 of the cleaner 200. The battery 240 can be disposed at the lower portion of the handle 216. The battery 240 can be disposed at the rear of the dust collecting bucket 220.

[0107] According to an embodiment, when the battery 240 is attached to the battery housing 230, the lower surface of the battery 240 can be exposed to the outside. When the vacuum cleaner 200 is lowered to the bottom, the battery 240 is likely to be placed on the bottom, so the battery 240 can be immediately separated from the battery housing 230. In addition, the lower surface of the battery 240 is exposed to the outside and directly contacts the external air of the battery 240, thereby improving the cooling performance of the battery 240.

[0108] On the other hand, when the battery 240 is integrally fixed to the battery case 230 , a structure for attaching and detaching the battery 240 and the battery case 230 can be omitted, so the overall size of the vacuum cleaner 200 can be reduced, and the weight can be reduced.

[0109] The cleaner 200 may include an extension pipe 250. The extension pipe 250 may be in communication with the cleaning module 260. The extension pipe 250 may be in communication with the main body 210. The extension pipe 250 may be in communication with the suction portion 212 of the main body 210. The extension pipe 250 may be formed in an elongated cylindrical shape.

[0110] The main body 210 can be connected to an extension tube 250. The main body 210 can be connected to a cleaning module 260 via the extension tube 250. The main body 210 can generate suction via a suction motor 214, and provide suction to the cleaning module 260 via the extension tube 250. External dust can flow into the main body 210 through the cleaning module 260 and the extension tube 250.

[0111] The cleaner 200 may include a cleaning module 260. The cleaning module 260 may be connected to the extension tube 250. Therefore, external air may flow into the main body 210 of the cleaner 200 through the cleaning module 260 and the extension tube 250 due to the suction force generated by the main body 210 of the cleaner 200.

[0112] Dust in the dust bucket 220 of the vacuum cleaner 200 is captured by gravity and the suction force of the dust collection motor 191 and then transferred to the dust collection unit 170 of the vacuum cleaner base station 100. This allows the dust in the dust bucket 220 to be removed without the user having to perform any additional operations, thereby improving user convenience. Furthermore, this eliminates the need for the user to empty the dust bucket 220 each time. Furthermore, when the dust bucket 220 is emptied, dust can be prevented from scattering.

[0113] The vacuum cleaner 200 can be coupled to the side of the housing 110. Specifically, the main body 210 of the vacuum cleaner 200 can be placed on the coupling portion 120. More specifically, the dust bucket 220 and the battery housing 230 of the vacuum cleaner 200 can be configured to face the coupling surface 121, the outer peripheral surface of the dust bucket main body 221 can be coupled to the dust bucket guide surface 122, and the suction portion 212 can be coupled to the suction portion guide surface 126 of the coupling portion 120. In this case, the central axis of the dust bucket 220 can be configured in a direction parallel to the ground, and the extension tube 250 can be configured in a direction perpendicular to the ground.

[0114] Reference Figure 1 as well as Figure 5 , the vacuum cleaner base station 100 of the present invention is described below.

[0115] The vacuum cleaner base station 100 may be configured with a vacuum cleaner 200. The vacuum cleaner 200 may be combined with the side of the vacuum cleaner base station 100. Specifically, the main body of the vacuum cleaner 200 may be combined with the side of the vacuum cleaner base station 100. The vacuum cleaner base station 100 may remove dust from the dust collection bucket 220 of the vacuum cleaner 200.

[0116] The vacuum cleaner base station 100 may include a housing 110. The housing 110 may form the appearance of the vacuum cleaner base station 100. Specifically, the housing 110 may be formed in a columnar shape including at least one outer wall surface 112. As an example, the housing 110 may be formed in a shape similar to a square column.

[0117] The housing 110 may internally form a space capable of accommodating a dust collecting portion 170 for storing dust and a dust suction module 190 for generating a flow force for collecting dust in the dust collecting portion 170 .

[0118] The housing 110 may include a bottom surface 111 , an outer wall surface 112 , and an upper surface 113 .

[0119] The bottom surface 111 can support the lower side of the dust suction module 190 in the gravity direction. In other words, the bottom surface 111 can support the lower side of the dust collecting motor 191 of the dust suction module 190.

[0120] In this case, the bottom surface 111 can be positioned toward the ground. The bottom surface 111 can be positioned parallel to the ground, or can be tilted at a predetermined angle to the ground. This structure can stably support the dust collection motor 191, providing the advantage of maintaining overall weight balance even when combined with the vacuum cleaner 200.

[0121] On the other hand, according to an embodiment, the bottom surface 111 may further include a ground support portion. To prevent the vacuum cleaner base station 100 from falling and maintain balance, the ground support portion increases the contact area with the ground. For example, the ground support portion may be in the form of a plate extending from the bottom surface 111, or may be in the form of one or more frames extending from the bottom surface 111 toward the ground.

[0122] The outer wall surface 112 may refer to a surface formed along the direction of gravity or may refer to a surface connected to the bottom surface 111. For example, the outer wall surface 112 may refer to a surface connected perpendicularly to the bottom surface 111. As a different embodiment, the outer wall surface 112 may be arranged to be inclined at a predetermined angle from the bottom surface 111.

[0123] The outer wall surface 112 may include at least one surface. For example, the outer wall surface 112 may include a first outer wall surface 112a, a second outer wall surface 112b, a third outer wall surface 112c, and a fourth outer wall surface 112d.

[0124] In this embodiment, the first outer wall 112a can be disposed on the front of the vacuum cleaner base station 100. The front refers to the side that exposes the vacuum cleaner 200 when the vacuum cleaner 200 is coupled to the vacuum cleaner base station 100. Therefore, the first outer wall 112a can form the front appearance of the vacuum cleaner base station 100.

[0125] On the other hand, in order to help understand the present embodiment, directions are defined as follows: In the present embodiment, directions can be defined in a state where the cleaner 200 is placed on the cleaner base station 100 .

[0126] When the vacuum cleaner 200 is placed on the vacuum cleaner base station 100 , the direction in which the vacuum cleaner 200 is exposed to the outside of the vacuum cleaner base station 100 may be referred to as the front.

[0127] From another perspective, when the cleaner 200 is placed on the cleaner base station 100, the direction in which the suction motor 214 of the cleaner 200 is arranged can be called the front. In addition, the direction opposite to the direction in which the suction motor 214 is arranged in the cleaner base station 100 can be called the rear.

[0128] In addition, based on the internal space of the housing 110, the surface facing the front direction can be called the back of the vacuum cleaner base station 100. Therefore, the back can refer to the direction in which the second outer wall surface 112b is formed.

[0129] In addition, with the interior space of the housing 110 as a reference, the left side when viewing the front face may be referred to as the left side, and the right side may be referred to as the right side. Therefore, the left side may refer to the direction in which the third outer wall surface 112 c is formed, and the right side may refer to the direction in which the fourth outer wall surface 112 d is formed.

[0130] The first outer wall surface 112 a is formed in a flat shape, but may be formed in a curved shape as a whole, or may be formed to include a curved surface partially.

[0131] The first outer wall 112a can have an appearance corresponding to the shape of the vacuum cleaner 200. Specifically, a coupling portion 120 can be disposed on the first outer wall 112a. This structure allows the vacuum cleaner 200 to be coupled to the vacuum cleaner base station 100 and supported by the vacuum cleaner base station 100. The specific structure of the coupling portion 120 will be described later.

[0132] On the other hand, a structure for placing cleaning modules 260 of various shapes used in the vacuum cleaner 200 can also be added to the first outer wall surface 112a.

[0133] In this embodiment, the second outer wall surface 112b may be the surface facing the first outer wall surface 112a. That is, the second outer wall surface 112b may be disposed on the back side of the vacuum cleaner base station 100. The back side may be the surface facing the surface to which the vacuum cleaner 200 or the second vacuum cleaner 300 is coupled. Therefore, the second outer wall surface 112b may form the outer appearance of the back side of the vacuum cleaner base station 100.

[0134] As an example, the second outer wall surface 112b may be formed in a flat shape. With this configuration, the vacuum cleaner base station 100 can be placed in close contact with a wall in the room, and the vacuum cleaner base station 100 can be stably supported.

[0135] As another example, a structure for placing cleaning modules 260 of various shapes used in the vacuum cleaner 200 may be added to the second outer wall surface 112b.

[0136] In this embodiment, the third outer wall surface 112c and the fourth outer wall surface 112d may refer to surfaces connecting the first outer wall surface 112a and the second outer wall surface 112b. In this case, the third outer wall surface 112c may be located on the left side of the base station 100, and the fourth outer wall surface 112d may be located on the right side of the vacuum cleaner base station 100. Alternatively, the third outer wall surface 112c may be located on the right side of the vacuum cleaner base station 100, and the fourth outer wall surface 112d may be located on the left side of the vacuum cleaner base station 100.

[0137] The third outer wall surface 112c or the fourth outer wall surface 112d may be formed in a flat shape, may be formed in a curved shape as a whole, or may be formed to include a curved surface partially.

[0138] On the other hand, a structure for placing cleaning modules 260 of various shapes used in the vacuum cleaner 200 may be added to the third outer wall 112c or the fourth outer wall 112d.

[0139] The upper surface 113 may form the upper appearance of the vacuum cleaner base station 100. That is, the upper surface 113 may refer to a surface that is disposed on the uppermost side in the gravity direction of the vacuum cleaner base station 100 and is exposed to the outside.

[0140] For reference, in an embodiment of the present invention, the direction of the vacuum cleaner base station 100 may be defined based on a state in which the bottom surface 111 of the vacuum cleaner base station 100 is located on the ground.

[0141] That is, the upper side and the lower side may respectively refer to the upper side and the lower side in the gravity direction (a direction perpendicular to the ground) when the cleaner base station 100 is placed on the ground.

[0142] In this case, the upper surface 113 may be arranged parallel to the ground, or may be arranged tilted at a predetermined angle from the ground.

[0143] A display unit 410 may be provided on the upper surface 113. For example, the display unit 410 may display the status of the vacuum cleaner base station 100 and the status of the vacuum cleaner 200, and may also display information such as the cleaning progress and a map of the cleaning area.

[0144] On the other hand, according to an embodiment, the upper surface 113 can be configured to be detachable from the outer wall surface 112. In this case, when the upper surface 113 is detached, the battery 240 detached from the vacuum cleaner 200 can be accommodated in the internal space surrounded by the outer wall surface 112, and a terminal (not shown) for charging the detached battery 240 can be provided.

[0145] On the other hand, the housing 110 may be formed with a protruding platform 116 for limiting the rotation path of the cover control frame 141 described later. Specifically, the housing 110 may have a space flow path portion 180 formed therein through which the air flowing in from the dust collecting bucket 220 can flow, and the protruding platform 116 may be protrudingly formed on the inner wall surface of the duct forming the flow path portion 180.

[0146] As another example, the protruding portion 116 may be formed at the upper portion of the dust passage hole 121 a of the housing 110 , and may be formed by protruding the upper portion of the inner side surface of the dust passage hole 121 a .

[0147] At this time, the protruding portion 116 may be disposed within a rotation radius of the cover control frame 141 .

[0148] Therefore, the cover control frame 141 contacts the protruding stage 116 , thereby limiting the rotation range of the cover control frame 141 . Specifically, the protruding stage 116 can provide an upper rotation limit of the cover control frame 141 .

[0149] Figure 6 FIG. 1 is a diagram for explaining a coupling portion in a vacuum cleaner base station according to an embodiment of the present invention. Figure 7 FIG. 1 is a diagram for explaining a fixing unit in a vacuum cleaner base station according to an embodiment of the present invention. Figures 8 to 10 1 is a diagram for explaining a cover control unit in a vacuum cleaner base station according to an embodiment of the present invention. Figure 13 A diagram illustrating a relationship between a vacuum cleaner and a cover opening unit in a vacuum cleaner base station according to an embodiment of the present invention is shown.

[0150] Reference Figure 5 as well as Figure 6 , the coupling portion 120 of the vacuum cleaner base station 100 of the present invention will be described below.

[0151] The vacuum cleaner base station 100 may include a coupling portion 120 for coupling with the vacuum cleaner 200. Specifically, the coupling portion 120 is disposed on the first outer wall surface 112a, and the main body 210, the dust collecting bucket 220 and the battery housing 230 of the vacuum cleaner 200 may be coupled to the coupling portion 120.

[0152] The coupling portion 120 may include a coupling surface 121. The coupling surface 121 may be disposed on a side surface of the housing 110. As an example, the coupling surface 121 may be a surface that is recessed from the first outer wall surface 112a toward the inner side of the vacuum cleaner base station 100 to form a groove. In other words, the coupling surface 121 may be a surface that forms a height difference with the first outer wall surface 112a.

[0153] The vacuum cleaner 200 can be accommodated in the coupling surface 121. As an example, the coupling surface 121 can face the lower side of the dust collecting bucket 220 and the battery housing 230 of the vacuum cleaner 200. The lower side can refer to the surface facing the ground when the user uses the vacuum cleaner 200 or places it on the ground.

[0154] As an example, the angle formed by the coupling surface 121 and the ground can be a right angle. Thus, when the vacuum cleaner 200 is coupled to the coupling surface 121, the space of the vacuum cleaner base station 100 can be minimized.

[0155] As another example, the coupling surface 121 may be arranged to be inclined at a predetermined angle from the ground. Thus, when the cleaner 200 is coupled to the coupling surface 121 , the cleaner base station 100 can be stably supported.

[0156] A dust hole 121a may be formed in the joint surface 121 to allow air outside the housing 110 to flow into the interior. The dust hole 121a may be formed to correspond to the shape of the dust bucket 220, so that dust in the dust bucket 220 flows into the dust collecting portion 170. The dust hole 121a may be formed to correspond to the shape of the discharge cover 222 of the dust bucket 220. The dust hole 121a may be formed to communicate with the flow path portion 180, which will be described later.

[0157] The coupling portion 120 may include a dust bucket guide surface 122 . The dust bucket guide surface 122 may be disposed on the first outer wall surface 112 a . The dust bucket guide surface 122 may be connected to the first outer wall surface 112 a . Furthermore, the dust bucket guide surface 122 may be connected to the coupling surface 121 .

[0158] The dust bucket guide surface 122 may be formed in a shape corresponding to the outer side surface of the dust bucket 220 . The outer side surface of the front of the dust bucket 220 may be coupled to the dust bucket guide surface 122 .

[0159] On the other hand, a protrusion moving hole 122a may be formed on the dust bucket guide surface 122, and the pushing protrusion 151 described later may move linearly along the protrusion moving hole 122a. In addition, a gear box 155 for accommodating the gears of the cover opening unit 150 described later may be provided on the lower side of the dust bucket guide surface 122 in the direction of gravity. At this time, a guide space 122b in which the pushing protrusion 151 can be moved may be formed between the dust bucket guide surface 122 and the upper side surface of the gear box 155. In addition, the above-mentioned guide space 122b may be connected to the first flow path portion 181 through the bypass hole 122c. That is, the protrusion moving hole 122a, the guide space 122b, the bypass hole 122c and the first flow path 181 may form a bypass flow path (refer to Figure 13 This structure has the advantage that when the dust collecting motor 191 is operating with the dust collecting bucket 220 coupled to the coupling portion 120, dust remaining in the dust collecting bucket 220 and the dust collecting bucket guide surface 122 can be sucked in through the bypass flow path.

[0160] The coupling portion 120 may include a guide protrusion 123. The guide protrusion 123 may be disposed on the coupling surface 121. The guide protrusion 123 may protrude from the coupling surface 121 toward the front of the vacuum cleaner base station 100. Two guide protrusions 123 may be provided, spaced apart from each other. The distance between the two spaced apart guide protrusions 123 may correspond to the width of the battery housing 230 of the vacuum cleaner 200. This facilitates coupling the vacuum cleaner 200 to the coupling surface 121.

[0161] The coupling portion 120 may include sidewalls 124. The sidewalls 124 may be walls disposed on either side of the coupling surface 121 and may be perpendicularly connected to the coupling surface 121. The sidewalls 124 may be connected to the first outer wall 112a. Furthermore, the sidewalls 124 may form a surface connected to the dust collection bucket guide surface 122. This allows for stable storage of the vacuum cleaner 200.

[0162] The coupling portion 120 may include a coupling sensor 125 . The coupling sensor 125 may sense whether the cleaner 200 is coupled to the coupling portion 120 .

[0163] The coupling sensor 125 may also include a contact sensor. For example, the coupling sensor 125 may include a micro switch. In this case, the coupling sensor 125 may be disposed on the guide protrusions 123. Therefore, when the battery housing 230 or the battery 240 of the vacuum cleaner 200 is coupled between the pair of guide protrusions 123, it contacts the coupling sensor 125, and the coupling sensor 125 can sense that the vacuum cleaner 200 is coupled.

[0164] Alternatively, the combined sensor 125 may include a non-contact sensor. For example, the combined sensor 125 may include an IR sensor. In this case, the combined sensor 125 may be disposed on the sidewall 124. Therefore, when the dust container 220 or the main body 210 of the vacuum cleaner 200 passes through the sidewall 124 and reaches the combined surface 121, the combined sensor 125 can sense the presence of the dust container 220 or the main body 210.

[0165] The coupling sensor 125 may face the dust collecting bucket 220 or the battery housing 230 of the cleaner 200 .

[0166] The coupling sensor 125 may be a member for determining whether power is applied to the battery 240 of the cleaner 200 and whether the cleaner 200 is coupled.

[0167] The coupling portion 120 may include a suction portion guide surface 126. The suction portion guide surface 126 may be disposed on the first outer wall surface 112a. The suction portion guide surface 126 may be connected to the dust collection container guide surface 122. The suction portion 212 may be coupled to the suction portion guide surface 126. The shape of the suction portion guide surface 126 may be formed to correspond to the shape of the suction portion 212.

[0168] The coupling portion 120 may further include a fixing member access hole 127. The fixing member access hole 127 may be formed in a long hole shape along the side wall 124 to allow the fixing member 131 to enter and exit.

[0169] With this configuration, when the user couples the vacuum cleaner 200 to the coupling portion 120 of the vacuum cleaner base station 100, the main body 210 of the vacuum cleaner 200 can be stably positioned on the coupling portion 120 via the dust bucket guide surface 122, the guide protrusion 123, and the suction portion guide surface 126. This facilitates coupling the dust bucket 220 and the battery housing 230 of the vacuum cleaner 200 to the coupling surface 121.

[0170] Reference Figure 5 、 Figure 7 as well as Figure 14 , the fixing unit 130 according to the present invention is described below.

[0171] The vacuum cleaner base station 100 of the present invention may include a fixing unit 130. The fixing unit 130 may be disposed on the side wall 124. The fixing unit 130 may secure the vacuum cleaner 200 coupled to the dust bucket guide surface 122. Specifically, the fixing unit 130 may secure the dust bucket 220 of the vacuum cleaner 200 coupled to the dust bucket guide surface 122.

[0172] The fixing unit 130 may include a fixing member 131 for fixing the dust collecting bucket 220 and the battery housing 230 of the cleaner 200 .

[0173] The fixing member 131 can be disposed on the side wall 124 of the coupling portion 120 and configured to be movable back and forth on the side wall 124 to fix the dust collecting container 220. Specifically, the fixing member 131 can be accommodated inside the fixing member access hole 127.

[0174] The fixing members 131 may be disposed on both sides of the coupling portion 120. For example, two fixing members 131 are symmetrically disposed in the left-right direction of the coupling surface 121 to form a pair.

[0175] The fixing member 131 can move toward the dust collecting bucket 220 when an external force is applied to fix the dust collecting bucket 220. Moreover, when the external force is released, the fixing member 131 fixing the dust collecting bucket 220 can move in a direction away from the dust collecting bucket 220.

[0176] For example, the fixing member 131 may be moved by the power of a motor. That is, the fixing member 131 may be moved by receiving power from at least one motor and a connecting rod connected to the motor.

[0177] As another example, the fixing member 131 may be moved by the suction force of the dust collecting motor 191. That is, the fixing member 131 may be moved by receiving the suction force through a flow path such as a hose.

[0178] On the other hand, the fixing unit 130 may further include a fixing sealer 136. The fixing sealer 136 may be disposed on the dust bucket guide surface 122 to achieve an airtight seal with the dust bucket 220 when the vacuum cleaner 200 is coupled. With this configuration, when the dust bucket 220 of the vacuum cleaner 200 is coupled, the weight of the vacuum cleaner 200 pressurizes the fixing sealer 136, thereby sealing the dust bucket 220 and the dust bucket guide surface 122.

[0179] Thus, the suction force of the cleaner can be improved by preventing residual dust from remaining in the dust collecting bucket 220. Furthermore, by preventing residual dust from remaining in the dust collecting bucket, the odor generated by the residual dust can be removed.

[0180] Reference Figure 5 、 Figures 8 to 10 as well as Figure 14 , the cover control unit 140 of the present invention is described below.

[0181] The vacuum cleaner base station 100 of the present invention may include a cover control unit 140. The cover control unit 140 may be configured to be manually operated by a user so as to close the discharge cover 222 of the dust collection container 220.

[0182] The lid control unit 140 may include a lid control frame 141 , a button 142 , and connection rods 143 , 144 .

[0183] The cover control frame 141 is hinged to the housing 110 and can fasten the discharge cover 222 to the dust collecting container 220 through the dust passing hole 121a. The cover control frame 141 may include a frame body 141a.

[0184] The frame body 141a can be formed into a plate shape that is long in the left-right direction. Based on the state that the frame body 141a is arranged vertically on the ground, the hinge part 141b can be arranged on the upper side of the frame body 141a, and the connecting rod connecting part 141c can be arranged on the lower side.

[0185] The hinge portion 141b is disposed at one end of the frame body 141a and is hinged to the housing 110 so as to be rotatable about the frame hinge axis a2. As an example, as shown in the figure, the hinge portion 141b is disposed in a pair along the left-right direction on the frame hinge axis a2.

[0186] The connecting rod coupling portion 141c may be a means for rotatably coupling the connecting rods 143 and 144. The connecting rod coupling portion 141c is disposed on the other side of the frame body 141a, and the connecting rods 143 and 144 are rotatably coupled to the other side end portion 141ca.

[0187] The connecting rod coupling portion 141 c is provided at the center of the frame body 141 a in the left-right direction, and the width thereof in the left-right direction may be formed to be narrower than the width of the frame body 141 a in the left-right direction.

[0188] That is, the connecting rod coupling portion 141c is formed into a plate shape arranged in the up and down direction so as to be able to press the coupling rod 222c side of the discharge cover 222, one end of which can be connected to the frame body 141a, and the other end is connected to the connecting rods 143 and 144 described later.

[0189] Thus, cover control frame 141, consisting of frame body 141a and connecting rod coupling portion 141c, is formed to block at least a portion of dust passage hole 121a. However, dust passage hole 121a need not be completely closed, and thus can be formed into a generally Y-shape. This reduces the weight of cover control frame 141 and the initial elastic support force required of elastic body 145, described later.

[0190] According to this configuration, the cover control frame 141 can be positioned at the first position and the second position by rotating.

[0191] When the cover control frame 141 is in the first position, as an example, the cover control frame 141 can be configured to be tilted at a predetermined angle to the ground. In this case, the predetermined angle means an angle of less than 90 degrees. Moreover, when the cover control frame 141 is in the first position, as another example, it can be configured to be tilted at a predetermined angle to the first outer wall surface 112a of the housing 110. As another example, the cover control frame 141 can be rotated and moved toward the inside of the vacuum cleaner base station 100 around the frame hinge axis a2 of the hinge portion 141b, so that the lower end of the cover control frame 141 is separated from the discharge cover 222. That is, a space can be formed between the cover control frame 141 and the discharge cover 222. This first position of the cover control frame 141 can represent an initial configuration state in which no external force is applied to the button 142.

[0192] When the lid control frame 141 is in the second position, as an example, the lid control frame 141 can be arranged perpendicular to the ground. Furthermore, when the lid control frame 141 is in the second position, as another example, it can be arranged parallel to the first outer wall surface 112a of the housing 110. As another example, the lid control frame 141 can rotate and move toward the outside of the vacuum cleaner base station 100 about the frame hinge axis a2 of the hinge portion 141b, so that the pressing protrusion 141e at the lower end of the lid control frame 141 presses the discharge cover 222. In other words, the second position of the lid control frame 141 can represent the configuration state when an external force is applied to the button 142.

[0193] Therefore, the cover control frame 141 can be in the first position, fully opening the dust passage hole 121a. In this state, the connecting rods 143 and 144 push the frame body 141a, causing the frame body 141a to rotate toward the outside of the vacuum cleaner base station 100 (rotate downward) about the hinge portion 141b. Thus, the cover control frame 141 can be in the second position, blocking at least a portion of the dust passage hole 121a, pressing the discharge cover 222 to hook and engage with the dust collection bucket 220. Furthermore, when the cover control frame 141 is in the second position, the connecting rods 143 and 144 pull the frame body 141a, causing the frame body 141a to rotate toward the inside of the vacuum cleaner base station 100 (rotate upward) about the hinge portion 141b, thereby fully opening the dust passage hole 121a.

[0194] Furthermore, the cover control frame 141 may include a protrusion 141d protruding outward from the vacuum cleaner base station 100. Specifically, the protrusion 141d may be formed on a surface of the cover control frame 141 that faces the discharge cover 222 when the cover control frame 141 is in the second position, and a portion of the surface of the cover control frame 141 excluding the hinge portion 141b may be formed to protrude in a stepped manner.

[0195] Also, at least one of the discharge cover 222 and the cover control frame 141 may include a pressing protrusion 141 e .

[0196] With the lid control frame 141 in the second position as a reference, the pressing protrusion 141e may project toward the lid control frame 141 from the portion where the coupling rod 222c of the discharge lid 222 is disposed. Alternatively, as shown in the figure, with the lid control frame 141 in the second position as a reference, the pressing protrusion 141e may project toward the discharge lid 222 from the connecting rod coupling portion 141c of the lid control frame 141. Specifically, the connecting rod may be coupled to one side of the other end portion 141ca of the connecting rod coupling portion 141c, and the pressing protrusion 141e may be formed on the other side.

[0197] Furthermore, the cover control frame 141 may include a stopper 141 f for supporting the protruding portion 116 of the housing 110 when the cover control frame 141 is located at the first position.

[0198] As an example, the stopper 141 f may be formed to protrude from the cover control frame 141 toward the inner side of the housing 110 , and may be formed at one end portion of the frame body 141 a .

[0199] The stopper 141f may be formed to gradually protrude as it moves away from one end of the frame body 141a, and the protruding end may be configured as an inclined surface supported by the protruding platform 116 when the cover control frame 141 is located at the first position.

[0200] Thus, during upward rotation, the stopper 141f is supported by the protruding platform 116, allowing the cover control frame 141 to be located in the first position. During downward rotation, the pressing protrusion 141e is supported by the discharge cover 222, allowing the cover control frame 141 to be located in the second position. In other words, the rotation path of the cover control frame 141 is limited to between the protruding platform 116 and the discharge cover 222. However, if the vacuum cleaner 200 is not coupled to the vacuum cleaner base station 100, during downward rotation, the cover control frame 141 can rotate until the button 142 is supported by the button mounting portion 114. Alternatively, if the vacuum cleaner 200 is not coupled to the vacuum cleaner base station 100, the button 142 moves to a position where it cannot move further downward, and the cover control frame 141 can rotate downward in conjunction with the button 142.

[0201] On the other hand, when the vacuum cleaner 200 is coupled to the vacuum cleaner base station 100 and the discharge cover 222 is separated from the dust collecting bucket body 210 , the discharge cover 222 can rotate toward the inside of the vacuum cleaner base station 100 through the torque spring 222 d and can contact the cover control frame 141 .

[0202] Such a lid control unit 140 may include a button 142 and connecting rods 143 and 144 so that a user can rotate the lid control frame 141 through manual operation.

[0203] The user can manually operate the button 142 by pressing it, and the button 142 can rotate the cover control frame 141 through linear motion. As an example, the button 142 can linearly move along the up and down directions.

[0204] Such a button 142 may be composed of an upper end portion 142a arranged along the movement direction and provided on the housing 110 so as to be exposed to the outside, a vertical wall portion 142b arranged at the upper end portion 142a along the movement direction, and a lower end portion 142c arranged at the lower end of the vertical wall portion 142b.

[0205] The upper end portion 142 a is inserted into the button mounting portion 114 of the housing 110 , thereby forming a partial appearance of the vacuum cleaner base station 100 .

[0206] The lower end portion 142 c is provided to be connected to the connecting rods 143 and 144 and to be provided with the elastic body 145 , and is arranged to face the upper end portion 142 a .

[0207] The lower end portion 142 c may include an elastic body fixing portion 142 d whose upper side is connected to the vertical wall portion 142 b and whose lower side is provided with an elastic body 145 .

[0208] The elastic body fixing portion 142d may be formed to protrude downward from the lower end portion 142c and may be formed into a cylindrical shape, for example. At least one elastic body fixing portion 142d may be provided at the lower end portion 142c, and the number of elastic body fixing portions 142d may be provided to correspond to the number of elastic bodies 145.

[0209] Furthermore, the lower end portion 142c may include a bent portion 142e connected to the rotating rod.

[0210] The bent portion 142e is arranged perpendicular to the lower end portion 142c, and as an example, may be extended from the right end portion of the lower end portion 142c and bent at a right angle.

[0211] The bent portion 142e may include a long hole 142f into which the connecting protrusion 143d of the rotating rod 143b is inserted and moved.

[0212] When the button 142 is linearly moved in a first direction, the elongated hole 142f can be arranged along a second direction perpendicular to the first direction. For example, the first direction can be perpendicular to the ground. In another example, the button 142 can be linearly moved in the vertical direction, the elongated hole 142f can be arranged along the front-to-back direction, and the connecting protrusion 143d can be inserted therein and move along the elongated hole 142f in the front-to-back direction.

[0213] The vertical wall portion 142b is disposed between the upper end portion 142a and the lower end portion 142c to connect the upper end portion 142a and the lower end portion 142c, and at least one vertical wall portion 142b may be provided.

[0214] Such a vertical wall portion 142b may be formed to be long in the up-down direction and may be formed in a plate shape consisting of a front surface and a rear surface or a plate shape consisting of a left surface and a right surface, but is not limited thereto.

[0215] The button mounting portion 114 formed on the housing 110 is configured to be exposed to the outside after the button 142 is inserted therein, and the upper surface of the button 142 can form a partial appearance of the vacuum cleaner base station 100 together with the housing 110 .

[0216] The button mounting portion 114 can be formed as a recessed hole in a portion of the upper surface 113 of the vacuum cleaner base station 100, formed by recessing a portion of the outer wall of the housing 110. The button 142 can be inserted into the inner side of the button mounting portion 114 to enable linear motion, and the button mounting portion 114 can guide the linear motion of the button 142. This allows the elastic body 145, described later, to be compressed or restored in the direction of the linear motion of the button 142.

[0217] Furthermore, the button mounting portion 114 may be formed by recessing a portion of the upper surface 113 and the outer wall surface 112 of the housing 110 . Furthermore, the button 142 may be formed in a shape corresponding to the button mounting portion 114 , thereby forming a partial appearance of the cleaner base station 100 .

[0218] As shown in the figure, when the button mounting portion 114 is formed by recessing a portion of the upper surface 113 and the outer wall surface 112 of the housing 110, the upper surface of the button 142 and the appearance forming portion 142ab formed by protruding downward from the upper end of the button 142 can form a partial appearance of the vacuum cleaner base station 100. In this case, the button mounting portion 114 can be recessed in the housing 110 along the linear motion direction of the button 142 to enable the button 142 to move linearly, thereby guiding the linear motion of the button 142.

[0219] The button 142 may be configured such that its upper surface is aligned with the upper surface 113 of the housing 110 , or may be configured such that the upper surface of the button 142 protrudes from the upper surface 113 of the housing 110 , without limitation.

[0220] The button 142 can be configured to form a height difference with the upper surface 113 of the housing 110 when an external force is applied, and can rotate the cover control frame 141. In addition, when the external force applied to the button 142 is released, the button 142 can move to its original position via the elastic body 145 described below, thereby causing the connecting rods 143 and 144 to rotate forward or reverse.

[0221] The "positive direction" here refers to the direction in which the connecting rods 143 and 144 push the cover control frame 141. Therefore, when the connecting rods 143 and 144 rotate in the positive direction, the cover control frame 141 rotates toward the outside of the cleaner base station 100, closing the discharge cover 222. Furthermore, when the connecting rods 143 and 144 rotate in the positive direction, the connection between the interior space of the dust collection bucket 220 and the flow path 180 is cut off.

[0222] Furthermore, the reverse direction may refer to the direction in which the connecting rods 143 and 144 pull the cover control frame 141. Therefore, by rotating the connecting rods 143 and 144 in the reverse direction, the cover control frame 141 rotates and moves toward the inside of the cleaner base station 100, thereby connecting the interior space of the dust collection bucket 220 with the flow path 180. The forward direction may be the opposite direction to the reverse direction.

[0223] The elastic body 145 elastically deforms when an external force is applied to the button 142 , thereby providing a restoring force to the button 142 . When the external force applied to the button 142 is released, the button 142 can be moved to its original position.

[0224] The elastic body 145 can be arranged along the direction of the linear motion of the button 142. As an example, it can be arranged perpendicular to the ground. As another example, the elastic body 145 can be arranged along the vertical direction.

[0225] One end portion of the elastic body 145 in the longitudinal direction may be fixed to the button 142, and the other end portion in the longitudinal direction may be fixed to the housing 110. That is, as an example, one end portion of the elastic body 145 in the longitudinal direction may be fixed to the elastic body fixing portion 142d, and the other end portion in the longitudinal direction may be fixed to the elastic body supporting portion 115 formed on the housing 110.

[0226] The elastic support portion 115 may be disposed inside the housing 110 , may be separated downward from the lower end portion, and may be disposed facing the lower end portion.

[0227] The elastic body support portion 115 may include a support member fixing portion 115a to which the other end portion in the longitudinal direction of the elastic body 145 is fixed. The support member fixing portion 115a may be disposed facing the elastic body fixing portion 142d and may be provided in the same number as the elastic bodies 145 .

[0228] Thus, the elastic body 145 is compressed in the vertical direction when the button 142 moves downward and approaches the elastic body support portion 115 , and is restored when the button 142 moves upward and away from the elastic body support portion 115 .

[0229] That is, when external force is applied to the button 142, the distance between the button 142 and the elastomer support portion 115 becomes narrower, and the elastomer 145 is compressed. When the external force applied to the button 142 is released, the button 142 can move upward away from the elastomer support portion 115 due to the restoring force of the elastomer 145.

[0230] The elastic body support portion 115 may have the same number of through-holes as the elastic body 145, through which the guide pins 146 described later may be inserted. Alternatively, the support member fixing portion 115a may be formed by protruding from the elastic body support portion 115 toward the button at the periphery of the through-holes. This support member fixing portion 115a may be formed into a hollow cylindrical shape, so that the guide pins 146 can be positioned inside the support member and can move linearly therein.

[0231] The guide pin 146 is arranged along the longitudinal direction of the elastic body 145 , thereby preventing the elastic body 145 from being bent or deformed and compressing the elastic body 145 in the longitudinal direction.

[0232] At least one guide pin 146 may be provided on the button 142 , and the same number of the guide pins 146 as the number of the elastic bodies 145 may be provided.

[0233] As an example, such a guide pin 146 can be disposed within the elastic body 145 and formed into a cylindrical shape, with its central axis aligned with the central axis of the elastic body 145. The guide pin 146 can be configured such that one end in the longitudinal direction is fixed to the button 142, thereby linearly moving with the button 142, and the other end in the longitudinal direction penetrates the elastic body support portion 115. Specifically, the guide pin 146 is disposed such that the other end in the longitudinal direction is disposed inside the support member fixing portion 115a, protruding downward from the elastic body support portion 115, and the linear motion of the guide pin 146 is guided by the support member fixing portion 115a. Furthermore, a support member 147 can be provided inside the support member fixing portion 115a to support the linear motion of the guide pin 146.

[0234] The support member 147 is arranged to surround the guide pin 146 and can be accommodated in the support member fixing portion 115a. In other words, it can be arranged to be inserted between the support member fixing portion 115a and the guide pin 146, and can be formed into a hollow shape, with the outer peripheral surface supporting the inner side of the support member fixing portion 115a and the inner peripheral surface supporting the outer peripheral surface of the guide pin 146.

[0235] In addition, the support member 147 can be fixed to the support member fixing portion 115a to support the linear motion of the guide pin 146. Such a support member 147 can be in close contact with the guide pin 146, thereby guiding the guide pin 146 to move in the vertical direction and preventing shaking during linear motion.

[0236] Furthermore, the other end portion of the elastic body 145 in the longitudinal direction may be fixed to any one of the support member 147 , the support member fixing portion 115 a , and the elastic body support portion 115 .

[0237] Thus, when an external force is applied to the button 142, the elastic body 145 is compressed, and the guide pin 146 moves downward together with the button 142, thereby increasing the length of the guide pin 146 protruding downward from the support member fixing portion 115a. Furthermore, when the external force applied to the button 142 is released, the elastic body 145 returns to its original position, and the guide pin 146 moves upward together with the button 142, thereby decreasing the length of the guide pin 146 protruding downward from the support member fixing portion 115a.

[0238] On the other hand, at least one elastic body 145 and at least one guide pin 146 may be provided. When only one elastic body 145 and guide pin 146 are provided, the center of weight of the button 142 may be located on its central axis.

[0239] Furthermore, two or more elastic bodies 145 and guide pins 146 may be provided to prevent the button 142 from being bent. Specifically, by providing two or more elastic bodies 145 and guide pins 146 spaced apart in the horizontal direction, even if pressure is applied to any portion of the upper end portion 142a of the button 142, the button 142 can be supported to allow for linear movement in the vertical direction.

[0240] On the other hand, the button 142 should be configured such that its upper surface should be aligned with the upper surface 113 of the housing 110 when no external force is applied, and the upper surface is exposed to the outside through the button mounting portion 114 .

[0241] For this purpose, the elastic body 145 is provided in a pre-compressed state so as to continuously provide an elastic supporting force to the upper support button 142 .

[0242] That is, the elastic body 145 is initially set in a pre-compressed first state to elastically support the button 142, and when an external force is applied to the button 142, it can be changed to a second state that is further compressed than the first state.

[0243] When the elastic body 145 is in the first state, an initial elastic supporting force is provided to the button 142, and the upper surface of the button 142 can be arranged side by side with the upper surface 113 of the housing 110. In this case, the initial elastic supporting force can be the same as or greater than the force required to arrange the upper surface of the button 142 and the upper surface 113 of the housing 110 side by side.

[0244] That is, the button 142 is set in the pre-compressed first state to avoid downward movement due to the load of the button 142 and the connecting rods 143 and 144, and an initial elastic supporting force can be provided to the button 142.

[0245] When an external force is applied to button 142, elastic body 145 can be changed to a second state. When elastic body 145 is in the second state, the upper surface of button 142 can be arranged in a stepped manner relative to upper surface 113 of housing 110. As a result, elastic body 145 in the second state is at least shorter than in the first state, providing an elastic supporting force to button 142 that is greater than the initial elastic supporting force. Furthermore, when the external force applied to button 142 is released, the restoring force of elastic body 145 returns button 142 to its pre-compressed first state.

[0246] The connecting rods 143 and 144 connect the cover control frame 141 and the button 142 , and rotate the cover control frame 141 by an external force input to the button 142 so that the cover control frame 141 closes the discharge cover 222 .

[0247] The connecting rods 143 and 144 connect the cover control frame 141 and the rotating rod 143 b , and the cover control frame 141 can be rotated by the rotational motion converted by the rotating rod 143 b .

[0248] As an example, the connecting rods 143 and 144 may include a first connecting rod 143 and a second connecting rod 1442 .

[0249] The first connecting rod 143 can rotate in response to the linear motion of the button 142. The first connecting rod 143 can rotate about a rotation axis a1, transferring the force transmitted from the button 142 to the second connecting rod 144. The rotation axis a1 can represent a virtual line extending the rotation axis of the first connecting rod 143. One end of the second connecting rod 144 can be rotatably coupled to the first connecting rod 143. The second connecting rod 1442 can push or pull the lid control frame 141 to close the discharge lid 222.

[0250] The first connecting rod 143 may include a rotating body 143 a , a rotating rod 143 b , and a first connecting rod body 143 c .

[0251] The rotating body 143 a rotates about the rotation axis a1 and, as an example, may be formed in a cylindrical shape about the rotation axis a1 .

[0252] The first connecting rod 143 may include a rotating rod 143b and a first connecting rod body 143c, each disposed radially opposite to the outside of the rotating body 143a. For example, the rotating body 143a may include the rotating rod 143b and the first connecting rod body 143c, which are formed to protrude radially outward. The protruding end of the rotating rod 143b is connected to the button 142, and the protruding end of the first connecting rod body 143c may be connected to the second connecting rod.

[0253] The rotating rod 143b and the first connecting rod body 143c, disposed on the rotating body 143a, can be arranged at a predetermined angle. When the first connecting rod 143 rotates about the rotation axis a1, the rotating rod 143b and the first connecting rod body 143c can maintain the predetermined angle. In other words, the rotating body 143a, the rotating rod 143b, and the first connecting rod body 143c rotate together and, as an example, can be integrally formed.

[0254] A rotating rod 143b may be provided to convert the linear motion of the button 142 into a rotating motion. For example, the rotating rod 143b may be formed in a frame shape arranged along the radial direction of the rotating body 143a.

[0255] The rotating lever 143 b includes a rotating body 143 a at one end in the longitudinal direction so as to be rotatable about the rotation axis a1 , and includes a connecting protrusion 143 d (described later) at the other end in the longitudinal direction so as to be connectable to the button 142 .

[0256] The rotating rod 143 b includes a connecting protrusion 143 d that is inserted and moved into the long hole 142 f of the button 142 , and can rotate around the rotation axis a1 when the button 142 moves linearly.

[0257] A connecting protrusion 143d can be formed to protrude from the other end of the rotating rod 143b toward the button 142 and can be inserted and moved within the elongated hole 142f. For example, as the button 142 moves downward, the connecting protrusion 143d can move rearward along the elongated hole 142f. Thus, when the button 142 moves linearly, the connecting protrusion 143d is inserted into and moves along the elongated hole 142f, allowing the rotating rod 143b to rotate about the rotation axis a1. The connecting protrusion 143d is guided by the elongated hole 142f, allowing it to move along the elongated hole 143d.

[0258] After being inserted into the elongated hole 142f, the end of the connecting protrusion 143d is secured with a fixing member 143e, thereby maintaining the connection within the elongated hole 142f. Specifically, the fixing member 143e is secured to the end that protrudes from one side of the bent portion 142e of the connecting protrusion 143d after insertion into the elongated hole 142f. The fixing member supports the other side of the bent portion 142e, thereby preventing the connecting protrusion 143d from falling out of the elongated hole 142f. In this case, the end of the connecting protrusion 143d may include a fixing member insertion groove for receiving the fixing member 143e. Furthermore, as an example, the fixing member 143e may be a snap ring with one side cut off, but this is not limited to this embodiment.

[0259] The first connecting rod body 143c rotates together with the rotating body 143a and can transmit the force transmitted by the button 142 to the second connecting rod 1442. For example, the first connecting rod body 143c is formed in a frame manner, with the rotating body 143a provided on one side in the longitudinal direction and rotatably coupled to the second connecting rod 1442 on the other side in the longitudinal direction.

[0260] The first connecting rod body 143c may be a rotating body that rotates about the rotation axis a1. In one example, one side in the longitudinal direction of the first connecting rod body 143c may be formed integrally with the rotating body 143a.

[0261] Therefore, along with the linear motion of the button 142 , the rotating rod 143 b and the first connecting rod body 143 c may rotate together.

[0262] The first connecting rod 143 is composed of only a rotating body 143a and a rotating rod 143b, and at least one portion of the first connecting rod 143 is rotatably connected to the second connecting rod 144. For example, the second connecting rod 144 can be connected to any portion of the rotating rod 143b.

[0263] In addition, as shown in the figure, the first connecting rod 143 is composed of a rotating body 143a, a rotating rod 143b and a first connecting rod body 143c, and the second connecting rod 144 is rotatably connected to the end of the first connecting rod body 143c, thereby reducing the force required for rotating the cover control frame 141.

[0264] The second connecting rod 1442 may include a second connecting rod body 144a and a frame connecting portion 1442b.

[0265] The second connecting rod body 144a can transmit the force of the first connecting rod 143 to the cover control frame 141. For example, the second connecting rod body 144a is formed in a frame manner, one side of the second connecting rod body 144a in the longitudinal direction is rotatably connected to the first connecting rod body 143c, and the other side in the longitudinal direction can be provided with a frame connecting portion 1442b.

[0266] The frame connection portion 1442b may be formed at the other side in the length direction of the second connection rod body 144a.

[0267] The frame connection portion 1442b may be coupled to the cover control frame 141. The frame connection portion 1442b may be hinged to the connecting rod coupling portion 141c. In this case, the hinge connecting the frame connection portion 1442b and the cover control frame 141 may become the rotation axis of the second connecting rod 1442.

[0268] According to this configuration, when the user presses the button 142 , the cover control frame 141 may be rotated to close the discharge cover 222 .

[0269] Reference Figure 8 as well as Figure 10 , Figure 8 In the first state, elastic member 145 provides an initial elastic support force to button 142, and stopper 141f is supported by protrusion 116 of housing 110, thereby allowing lid control frame 141 to be positioned in the first position. At this point, stopper 141f is supported by protrusion 116, restricting the upward movement of lid control frame 141 and the upward movement of button 142 connected thereto. This allows the upper surface of button 142 to be aligned with upper surface 113 of housing 110.

[0270] If an external force is applied to the button 142, Figure 10 As shown, the button 142 moves downward, the elastic body 145 is compressed into the second state, and the connecting protrusion 143d inserted into the long hole 142f moves backward, allowing the connecting rods 143 and 144 to rotate. Among them, the first connecting rod 143 rotates, and the other side of the first connecting rod body 143c in the longitudinal direction is located on the relatively lower side. The position of the second connecting rod body 144a is located on the relatively lower side, and the frame connecting portion 144b can also be located on the lower side. In this way, after the connecting rods 143 and 144 rotate, they push the cover control frame 141, and the cover control frame 141 can rotate downward with the hinge portion 141b as the axis. At this time, the cover control frame 141 rotates downward until the discharge cover 222 is fastened to the dust collection bucket 220, so that the discharge cover 222 can be closed.

[0271] In addition, when the external force applied to the button 142 is released, the Figure 8As shown, the restoring force of elastic body 145 causes button 142 to move upward, and connecting protrusion 143d inserted into slot 142f moves forward, allowing connecting rods 143 and 144 to rotate. Furthermore, the rotation of connecting rods 143 and 144 pulls lid control frame 141, allowing lid control frame 141 to rotate upward about hinge 141b. At this point, lid control frame 141 can rotate upward until stopper 141f is supported by protruding platform 116. Elastic body 145 returns to its first state, providing initial elastic support force to button 142. This allows button 142 to move upward until its upper surface is aligned with upper surface 113 of housing 110.

[0272] In this way, by converting the external force applied to the button 142 into a rotational motion and transmitting it to the lid control frame 141 via the connecting rods 143 and 144, the force of the lid control frame 141 to close the discharge lid 222 can be greater than the force transmitted to the connecting rods 143 and 144 via the button 142. Therefore, even if the external force applied to the button 142 is small, a force sufficient to close the discharge lid 222 can be generated.

[0273] Therefore, the user can simply close the discharge cover 222 by operating the button 142, without providing an existing motor for closing the discharge cover 222, thereby reducing the number of parts, reducing weight, and preventing noise caused by the motor.

[0274] Figure 11 as well as Figure 12 FIG. 1 is a diagram for explaining a cover control unit in a vacuum cleaner base station according to another embodiment of the present invention.

[0275] Reference Figure 11 as well as Figure 12 , describing the lid control unit 140 of the vacuum cleaner base station 100 according to other embodiments of the present invention. The first connecting rod 143 in the lid control unit 140 may include a connecting shaft seal 143f. The vacuum cleaner base station 100 according to other embodiments merely further includes the connecting shaft seal 143f based on the vacuum cleaner base station 100 according to the first embodiment. Therefore, to avoid duplication, descriptions of components other than the connecting shaft seal 143f are omitted.

[0276] The connecting shaft seal 143f is positioned between the rotating rod 143b and the first connecting rod body 143c along the rotation axis a1, thereby separating the rotating rod 143b from the first connecting rod body 143c. Specifically, the length of the connecting shaft seal 143f is adjusted to the desired separation distance between the rotating rod 143b and the first connecting rod body 143c, thereby enabling the rotating rod 143b and the first connecting rod body 143c to be positioned a desired distance apart on the rotation axis a1. The connecting shaft seal 143f can be positioned coaxially with the rotating body 143a. For example, the rotating body 143a can be extended along the rotation axis a1.

[0277] One end portion of the connecting shaft seal 143 f on the rotation axis a1 may be configured with an end portion of the rotating rod 143 b , and the other end portion may be configured with an end portion of the first connecting rod body 143 c .

[0278] The connection shaft seal 143 f is provided in order to separate the positions of the button 142 and the cover control frame 141 in the left-right direction of the housing 110 .

[0279] That is, preferably, the cover control frame 141 is arranged in the center in the left-right direction so that when closing the discharge cover 222, the portion adjacent to the coupling rod 222c is pressed to close the discharge cover 222, and preferably, the connecting rod coupling portion 141c is also arranged in the center in the left-right direction of the cover control frame 141. At this time, when the connecting shaft seal 143f is not provided on the rotating rod 143b, the button 142 can be arranged in the center in the left-right direction of the housing 110 or in a position adjacent to the center in the left-right direction of the housing 110. In addition, when the rotating rod 143b is provided with the connecting shaft seal 143f, the button 142 can be arranged in a position separated from the center in the left-right direction of the housing 110. As an example, Figure 11 As shown, the button 142 can be configured at the left end of the housing 110 .

[0280] In this way, by providing the connecting shaft seal 143f on the rotating rod 143b, the setting position of the button 142 can be easily changed, the design of the housing 110 can be improved, and the button 142 can be arranged at a position that is easily accessible to the user.

[0281] Furthermore, since the housing 110 needs to have a space in the center of the upper end to accommodate and charge the battery 240 that has been separated from the vacuum cleaner 200, by providing a connecting shaft seal 143f, the button 142 is positioned away from the center of the housing in the horizontal direction, thereby flexibly ensuring space for the button 142. This also ensures sufficient vertical movement distance for the button 142, preventing the button 142 from interfering with surrounding components during vertical movement.

[0282] Furthermore, although not shown in the accompanying drawings, the connecting shaft seal 143f can also be provided on any one of the rotating body 143a of the first connecting rod body 143c, the frame connection portion of the second connecting rod body 144a, and the end portion of the first connecting rod body 143c and the second connecting rod body 144a where rotation is combined.

[0283] Refer to the following Figure 5 、 Figure 13 as well as Figure 14 The cover opening unit 150 of the present invention will be described.

[0284] The vacuum cleaner base station 100 of the present invention may include a cover opening unit 150 . The cover opening unit 150 is disposed at the coupling portion 120 and can open the discharge cover 222 of the vacuum cleaner 200 .

[0285] The cover opening unit 150 may include a push protrusion 151 , a cover opening motor 152 , a cover opening gear 153 , a support plate 154 , and a gear box 155 .

[0286] When the cleaner 200 is coupled, the pushing protrusion 151 may move in a manner of pressurizing the coupling rod 222 c .

[0287] The pushing protrusion 151 may be configured on the dust collecting bucket guide surface 122. Specifically, the dust collecting bucket guide surface 122 may be formed with a protrusion moving hole, and the pushing protrusion 151 may be exposed to the outside after passing through the protrusion moving hole.

[0288] The pushing protrusion 151 can be arranged at a position that can press the coupling rod 222c when the vacuum cleaner 200 is coupled. That is, the coupling rod 222c can be arranged on the protrusion moving hole. In addition, the coupling rod 222c can be arranged on the moving area of ​​the pushing protrusion 151.

[0289] The push protrusion 151 can perform a linear reciprocating motion to press the coupling rod 222c. Specifically, the push protrusion 151 is coupled to the gear box 155 so that the linear motion is guided. The push protrusion 151 is coupled to the cover opening gear 153 so that it can move together with the movement of the cover opening gear 153.

[0290] The cover opening motor 152 can provide power to move the push protrusion 151. Specifically, the cover opening motor 152 can cause the motor shaft (not shown) to rotate in a forward or reverse direction. The forward direction can refer to the direction in which the push protrusion 151 presses the coupling rod 222c. The reverse direction can refer to the direction in which the push protrusion 151 pressing the coupling rod 222c returns to its original position. The forward direction can be the opposite direction to the reverse direction.

[0291] The cover opening gear 153 is combined with the cover opening motor 152, and the push protrusion 151 can be moved by the power of the cover opening motor 152. Specifically, the cover opening gear 153 can be housed inside the gear box 155. The driving gear 153a of the cover opening gear 153 is combined with the motor shaft of the cover opening motor 152, so that it can receive power. The driven gear 153b of the cover opening gear 153 is combined with the push protrusion 151, so that the push protrusion 151 can be moved. As an example, the driven gear 153b is constructed in a rack manner, so that it meshes with the driving gear 153a and can receive power from the driving gear 153a.

[0292] In this case, the discharge cover 222 may be provided with a torque spring 222d. The elastic force of the torque spring 222d allows the discharge cover 222 to rotate beyond a predetermined angle and remain supported in the rotated position. Thus, the discharge cover 222 can be opened, allowing the dust passage hole 121a to communicate with the interior of the dust collection container 220.

[0293] The gear box 155 is provided inside the housing 110 and is disposed on the lower side of the coupling portion 120 in the direction of gravity. The cover opening gear 153 can be accommodated therein.

[0294] The gear box 155 may be provided with a cover-opening sensor 155f. In this case, the cover-opening sensor 155f may also include a contact sensor. As an example, the cover-opening sensor 155f may include a micro switch. Alternatively, the cover-opening sensor 155f may include a non-contact sensor. As an example, the cover-opening sensor 155f may include an IR sensor.

[0295] The cover opening sensor 155f can be disposed on at least one of the inner side surface or the outer side surface of the gear box 155. As an example, one cover opening sensor 155f can be disposed on the inner side surface of the gear box 155. In this case, the cover opening sensor 155f can sense that the push protrusion 151 is at the initial position.

[0296] As another example, two cover-opening sensing parts 155f can be configured on the outer side surface of the gear box 155. In this case, the cover-opening sensing parts 155f can sense the initial position of the pushing protrusion 151 and the cover-opening position.

[0297] Therefore, according to the present invention, the user can open the dust collecting container 220 through the cover opening unit 150 without specifically opening the discharge cover 222 of the cleaner 200, thereby improving convenience.

[0298] Furthermore, since the discharge cover 222 is opened in a state where the cleaner 200 is coupled to the cleaner base station 100 , it is possible to prevent dust from being scattered.

[0299] On the other hand, refer to Figure 5 as well as Figure 14 The dust collecting portion 170 will be described.

[0300] The cleaner base station 100 may include a dust collecting portion 170. The dust collecting portion 170 may be disposed inside the housing 110. The dust collecting portion 170 may be disposed on the lower side of the coupling portion 120 in the direction of gravity.

[0301] As an example, the dust collecting unit 170 may be a dust bag that collects dust sucked from the dust collecting container 220 of the cleaner 200 by the dust collecting motor 191 .

[0302] The dust collecting portion 170 may be detachably coupled to the housing 110 .

[0303] Therefore, the dust collecting unit 170 can be removed from the housing 110 and discarded, and a new dust collecting unit 170 can be coupled to the housing 110. That is, the dust collecting unit 170 can be defined as a consumable component.

[0304] The dust bag may be configured to increase in volume when suction is generated by the dust collecting motor 191 and to store dust therein.

[0305] For this purpose, the dust bag can be formed of a material that is permeable to air but impermeable to dust and other impurities. As an example, the dust bag can be made of a non-woven fabric material and can have a hexahedral shape when the volume is increased.

[0306] Therefore, the user does not need to bundle a bag or the like for capturing dust, so user convenience can be improved.

[0307] Alternatively, the dust bag can be made of a tubular plastic (not shown). This configuration prevents dust or odor trapped inside the dust bag from leaking out after the dust bag is sealed or joined. In this case, the dust bag can be attached to the housing 110 via a dust bag box (not shown). The dust bag can be replaced as needed using the dust bag box.

[0308] On the other hand, the dust collecting portion 170 may be provided with a temperature sensor 175. The temperature sensor 175 may measure the temperature inside the dust collecting portion 170. The temperature information measured by the temperature sensor 175 may be received by the control portion 400.

[0309] On the other hand, according to an embodiment, the temperature sensor 175 may also be provided in the dust suction module 190. When the temperature sensor 175 is provided in the dust suction module 190, the temperature of the dust collection motor 191 or the temperature of the air ejected from the dust collection motor 191 is measured, thereby calculating the temperature of the air flowing into the dust collection unit 170.

[0310] On the other hand, refer to Figure 5as well as Figure 14 The flow path portion 180 will be described.

[0311] The cleaner base station 100 may include a flow path unit 180 .

[0312] The flow path 180 can connect the dust bucket 220 of the vacuum cleaner 200 and the dust collection unit 170. The flow path 180 can be located behind the joint surface 121. The flow path 180 can refer to the space between the dust bucket 220 of the vacuum cleaner 200 and the dust collection unit 170. The flow path 180 can be formed by bending downward from the dust passage hole 121a to form a flow path that allows dust and air to flow.

[0313] Specifically, when the cleaner 200 is coupled to the cleaner base station 100 and the dust through hole 121 a is opened, the first flow path 181 communicating with the inner space of the dust collecting bucket 220 and the second flow path 182 communicating between the first flow path 181 and the inner space of the dust collecting portion 170 may be included.

[0314] As an example, the first flow path 181 may be arranged substantially parallel to the axis of the suction motor 214 or a virtual through line passing through the dust container 220 . In this case, the axis of the suction motor 214 or the through line passing through the dust container 220 may pass through the first flow path 181 .

[0315] In this case, the second flow path 182 may be formed at a predetermined angle to the first flow path 181. For example, the first flow path 181 and the second flow path 182 may be formed at a right angle. This configuration can minimize the overall volume of the cleaner base station 100.

[0316] The second flow path 182 is formed to extend downward from the first flow path 181 and communicates with the first flow path 181 , thereby being able to guide the air passing through the first flow path 181 to the dust collecting portion 170 .

[0317] The second flow path 182 may be arranged in a direction parallel to the axis C of the dust collecting motor 191. With this configuration, it is possible to minimize attenuation of the suction force of the dust collecting motor 191 in the first flow path 181 and the second flow path 182.

[0318] The dust in the dust collecting container 220 of the cleaner 200 can be moved to the dust collecting portion 170 through the flow path portion 180 .

[0319] On the other hand, refer to Figure 5 as well as Figure 14 The dust suction module 190 is described.

[0320] The cleaner base station 100 may include a dust suction module 190. The dust suction module 190 may include a dust collecting motor 191, a first filter (not shown), and a second filter (not shown).

[0321] The dust collecting motor 191 may be disposed at the lower portion of the dust collecting portion 170. The dust collecting motor 191 may generate suction force in the flow path portion 180. Thus, the dust collecting motor 191 may provide suction force that may suck in the dust in the dust collecting container 220 of the vacuum cleaner 200.

[0322] The dust collecting motor 191 can generate suction by rotating. As an example, the dust collecting motor 191 can be formed in a shape similar to a cylinder.

[0323] On the other hand, in this embodiment, a virtual dust collecting motor axis extending the rotation axis of the dust collecting motor 191 may be formed.

[0324] A first filter (not shown) may be disposed between the dust collecting portion 170 and the dust collecting motor 191. The first filter may be a pre-filter.

[0325] The second filter (not shown) may be disposed between the dust collecting motor 191 and the outer wall surface 112. The second filter (not shown) may be a high efficiency (HEPA) filter.

[0326] On the other hand, the vacuum cleaner base station 100 may further include a charging unit 128. The charging unit may be disposed on the coupling portion 120. The charging unit 128 may be electrically connected to the vacuum cleaner 200 coupled to the coupling portion 120. The charging unit 128 may supply power to the battery of the vacuum cleaner 200 coupled to the coupling portion 120.

[0327] Furthermore, the vacuum cleaner base station 100 may further include a side door (not shown). The side door may be configured on the housing 110. The side door may selectively expose the dust collection unit 170 to the outside. Thus, the user can easily remove the dust collection unit 170 from the vacuum cleaner base station 100.

[0328] on the other hand, Figure 14 A block diagram for explaining a control structure in a vacuum cleaner base station according to an embodiment of the present invention is shown.

[0329] Reference Figure 14 , the control structure of the vacuum cleaner base station 100 of the present invention is described below.

[0330] According to an embodiment of the present invention, the vacuum cleaner base station 100 may further include a control unit 400 for controlling the combining portion 120 , the fixing unit 130 , the dust bucket cover control unit 140 , the cover opening unit 150 , the dust collecting portion 170 , the flow path portion 180 and the dust suction module 190 .

[0331] The control unit 400 may be composed of a circuit substrate and components mounted on the circuit substrate.

[0332] When the coupling sensor 125 senses the coupling of the cleaner 200, the coupling sensor 125 may send a signal indicating that the cleaner 200 is coupled to the coupling portion 120. At this time, the control unit 400 receives the signal from the coupling sensor 125 and may determine that the cleaner 200 is coupled to the coupling portion 120.

[0333] Furthermore, when the charging unit 128 supplies power to the battery 240 of the cleaner 200 , the control unit 400 may determine that the cleaner 200 is coupled to the coupling unit 120 .

[0334] When it is determined that the vacuum cleaner 200 is coupled to the coupling portion 120 , the control unit 400 activates the cover-opening motor 152 to open the discharge cover 222 of the vacuum cleaner 200 .

[0335] When the guide protrusion 123 moves rearward, the support plate 154 can reach a predetermined open position. When the support plate 154 reaches the predetermined open position, the cover-opening sensor 155f can send a signal to open the discharge cover 222. Upon receiving the signal from the cover-opening sensor 155f indicating that the discharge cover 222 is open, the control unit 400 can determine that the discharge cover 222 is open. Upon determining that the discharge cover 222 is open, the control unit 400 can stop the cover-opening motor 152.

[0336] The control unit 400 can drive the dust collecting motor 191 to suck in the dust inside the dust collecting container 220 .

[0337] The control unit 400 may activate the display unit 410 to display information about the emptying status of the dust container of the cleaner 200 and the charging status.

[0338] On the other hand, the vacuum cleaner base station 100 of the present invention may include a display unit 410 .

[0339] The display unit 410 may be configured in the housing 110 or in a separate display device, and may be provided in a terminal device including a mobile phone.

[0340] The display unit 410 may include at least one of a display panel capable of outputting text and / or graphics and a speaker capable of outputting audio signals and sound. The user can easily understand the status of the current trip, the remaining time, etc. through the information output by the display unit.

[0341] On the other hand, the vacuum cleaner base station 100 according to an embodiment of the present invention may include a memory 430. The memory 430 may include various data used for driving and operating the vacuum cleaner base station 100.

[0342] On the other hand, the vacuum cleaner base station 100 according to an embodiment of the present invention may include an input unit 440. The input unit 440 generates key input data entered by a user to control the operation of the vacuum cleaner base station 100. To this end, the input unit 440 may be configured as a keypad, a dome switch, a touchpad (resistance / capacitance), etc. In particular, when the touchpad and the display unit 410 form a layered structure, it may be referred to as a touch screen.

[0343] In addition, after the operation of the dust collecting motor 191 ends, the user can confirm the emptying status of the dust collecting container by checking the display unit 410 and press the button 142 to close the discharge cover 222.

[0344] That is, the user may apply an external force to the button 142 to activate the cover control unit 140 , and the discharge cover 222 may be fastened to the dust container 220 through the cover control unit 140 .

[0345] This can save the user from the trouble of personally closing the discharge cover 222 of the dust collecting container 220 , prevent the dust collecting container 220 from being exposed with the discharge cover 222 not closed, and prevent dust from scattering.

[0346] Furthermore, the control unit 400 may install other sensors on the push protrusion 151 or the cover control frame 141 to sense the position of the discharge cover 222 or whether it is closed, and may display whether the discharge cover 222 is closed on the display unit 410. Furthermore, when the vacuum cleaner 200 is separated from the vacuum cleaner base station 100 with the discharge cover 222 open, the control unit 400 may generate a warning sound, a warning light, a warning message, etc. In this case, the warning message may convey the message "Press the button 142 to close the discharge cover 222."

[0347] Figure 15 A flow chart for explaining a control method of a vacuum cleaner system according to the present invention is shown.

[0348] Reference Figures 5 to 15 , the following describes a control method for a vacuum cleaner base station according to an embodiment of the present invention.

[0349] The control method of the vacuum cleaner base station of the present invention includes a combination confirmation step (S10), a cover opening step (S20), a collection step (S30) and a cover closing step (S40).

[0350] In the coupling confirmation step ( S10 ), it may be confirmed whether the vacuum cleaner 200 is coupled to the coupling portion 120 of the vacuum cleaner base station 100 .

[0351] Specifically, in the coupling confirmation step (S10), when the vacuum cleaner 200 is coupled to the coupling portion 120, the coupling sensor 125 disposed on the guide protrusion 123 may contact the battery housing 230, and the coupling sensor 125 may send a signal indicating that the vacuum cleaner 200 is coupled to the coupling portion 120. Alternatively, according to an embodiment, the presence of the dust collection bucket 220 may be sensed by the coupling sensor 125 of a non-contact sensor type disposed on the side wall 124, and the coupling sensor 125 may send a signal indicating that the vacuum cleaner 200 is coupled to the coupling portion 120.

[0352] Therefore, in the coupling confirmation step ( S10 ), the control unit 400 receives a signal generated by the coupling sensor 125 and can determine that the cleaner 200 is coupled to the coupling portion 120 .

[0353] Alternatively, in the coupling confirmation step ( S10 ) of the present invention, the control unit 400 may sense whether the vacuum cleaner 200 is coupled to the correct position based on whether the charging unit 128 supplies power to the battery 240 of the vacuum cleaner 200 .

[0354] In the cover opening step ( S20 ), when the dust collecting bucket 220 is coupled to the cleaner base station 100 , the control unit 400 may open the discharge cover 222 of the cleaner 200 .

[0355] When receiving a signal from the fixing sensor 137 that the dust collecting container 220 is fixed, the control unit 400 may start the cover opening motor 152 in the forward direction to open the discharge cover 222 .

[0356] Specifically, the control unit 400 can drive the cover-opening motor 152 in the forward direction. As a result, the protrusion 151 is pushed out of its initial position and moves to the position of the pressure-applying coupling rod 222c. Therefore, the movement of the coupling rod 222c releases the hook connection between the discharge cover 222 and the dust bucket body 221. Due to the restoring force of the torque spring 222d, the discharge cover 222 rotates away from the dust bucket body 221, thereby being separated.

[0357] On the other hand, before the pushing protrusion 151 presses the coupling rod 222 c , the cover-opening sensing portion 155 f may send a signal indicating that the pushing protrusion 151 is located at the initial position.

[0358] When the cover opening motor 152 is started and the protrusion 151 starts to move and the pressurized coupling rod 222c is pressed, the cover opening sensing portion 155f can send a signal that the protrusion 151 has broken away from the initial position. In addition, the control unit 400 receives this signal and can determine that the cover opening unit 150 is working properly.

[0359] At this time, the control unit 400 may measure the time after the cover opening motor 152 is driven in the forward direction or the time after the protrusion 151 is pushed away from the initial position through a timer (not shown).

[0360] At this time, the control unit 400 can preset and store the time required for the push protrusion 151 to move from its initial position to press the coupling bar 222c based on the rotation speed of the lid opening motor 152 and the travel distance of the push protrusion 151. Therefore, the control unit 400 can drive the lid opening motor 152 in the forward direction during the lid opening time tc1, where the lid opening time tc1 is greater than the time required to press the coupling bar 222c. As an example, the control unit 400 can drive the lid opening motor 152 in the forward direction for a period of 4 seconds to 5 seconds.

[0361] In addition, after the cover-opening time tc1 has elapsed, the control unit 400 may switch the rotation direction of the cover-opening motor 152 during a preset rotation direction switching time tc2.

[0362] In addition, after the rotation direction switching time tc2 has elapsed, the control unit 400 may reversely drive the cover opening motor 152. As a result, the pushing protrusion 151 may return to its initial position.

[0363] The control unit 400 can drive the lid opening motor 152 until the lid opening sensor 155f senses that the push protrusion 151 has returned to its initial position. At this point, the control unit 400 can preset and store the protrusion return time tc3 required for the push protrusion 151 to return to its initial position after pressing the coupling rod 222c. Therefore, the control unit 400 can reverse the lid opening motor 152 for the duration of the protrusion return time tc3. For example, the control unit 400 can reverse the lid opening motor 152 for a period of 4 to 5 seconds.

[0364] On the other hand, when the control unit 400 receives a signal from the cover-opening sensor 155 f that pushes the protrusion 151 to return to the initial position, the control unit 400 may stop driving the cover-opening motor 152 .

[0365] As a result, after the cover opening step (S20) is performed, the discharge cover 222 of the dust bucket 220 rotates, and at the same time, the space inside the dust bucket body 221 is opened, so that the internal space of the dust bucket 220 can communicate with the flow path portion 180 (specifically, the first flow path 181) of the cleaner base station 100. At this time, the cover control frame 141 can be located at the first position that fully opens the dust through hole 121a.

[0366] In the collecting step ( S30 ), the discharge cover 222 is opened, and the dust collecting motor 191 is started to collect the dust inside the dust collecting container 220 .

[0367] For example, in the collecting step ( S30 ), the control unit 400 may start the operation of the dust collecting motor 191 after receiving a signal from the cover opening sensor 155 f indicating that the discharge cover 222 is opened.

[0368] As another example, the control unit 400 may start the operation of the dust collection motor 191 when a time of 6 seconds to 7 seconds has passed since the dust collection bucket is connected or the user inputs an operation.

[0369] In the collection step (S30), the control unit 400 may start the dust collection motor 191 to rotate at a preset dust collection speed Ws for a preset dust collection time ts. As an example, in the collection step (S30), the control unit 400 may start the dust collection motor 191 to rotate at the preset dust collection speed Ws for a period of 5 seconds to 9 seconds, but is not limited thereto. The dust collection time may be changed according to the output of the dust collection motor 191 and the amount of dust stored in the dust collection bucket 220.

[0370] According to the collecting step (S30), the dust inside the dust collecting bucket 220 can be collected in the dust collecting portion 170 through the dust passing hole 121a and the flow path portion 180. Therefore, the user can remove the dust in the dust collecting bucket 220 without performing other operations, thereby having the effect of improving user convenience.

[0371] On the other hand, in the present invention, according to an embodiment, the dust collection bucket 220 can be simultaneously fixed during the collection step (S30). Specifically, during the collection step (S30), the suction force of the dust collection motor 191 can activate the fixing unit 130. That is, during the collection step (S30), the suction force of the dust collection motor 191 can move the fixing member 131 in a direction that presses against the dust collection bucket 220.

[0372] With this configuration, even if vibration occurs in the cleaner base station 100 due to the operation of the dust collecting motor 191 , the dust collecting bucket 220 can be stably fixed.

[0373] Therefore, according to the present invention, the time required to fix or release the cleaner 200 is reduced, thereby having an effect of reducing the overall working time.

[0374] On the other hand, the control method of the vacuum cleaner base station according to an embodiment of the present invention may further include a cover closing step (S40) of rotating the cover control frame 141 to close the discharge cover 222 after the dust collection motor 191 ends operation. In this cover closing step (S40), the user can press the button 142 to close the discharge cover 222.

[0375] In the cover closing step ( S40 ), in order to close the discharge cover 222 of the cleaner 200 , the user may press the button 142 , and when an external force is applied to the button 142 , the cover control unit 140 may start working to close the discharge cover 222 .

[0376] Specifically, according to the lid control unit 140, when an external force is applied to the button 142, the button 142 moves downward, thereby compressing the elastic body 145, and rotating the connecting rods 143 and 144 connected to the button 142. The connecting rods 143 and 144 are connected to the lid control frame 141, so that the lid control frame 141 can rotate downward until the lid control frame 141 closes the discharge lid 222.
