Description

Technical Field

[0001] The present invention relates to a vacuum cleaner base station, and more particularly, to a vacuum cleaner base station which, when a vacuum cleaner is coupled to the vacuum cleaner base station, can automatically open and close a dust box cover of the vacuum cleaner to collect dust in the dust box. Background Art

[0002] Generally, a vacuum cleaner is a household appliance that uses electricity to draw in air to suck in small garbage and dust, and fills a dust box in the product.

[0003] Such vacuum cleaners are divided into manual vacuum cleaners that the user moves the vacuum cleaner directly to clean and automatic vacuum cleaners that clean while walking. Manual vacuum cleaners are divided into barrel vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick vacuum cleaners according to their shape.

[0004] Among household vacuum cleaners, canister-type vacuum cleaners have been the most commonly used in the past. However, in recent years, there has been an increasing trend in the use of handheld vacuum cleaners and stick-type vacuum cleaners that improve usability by integrating a dust box with a vacuum cleaner body.

[0005] In a barrel-type vacuum cleaner, the main body and the suction port are connected by a rubber hose or a duct, and a brush can be inserted into the suction port for use, depending on the situation.

[0006] A handheld vacuum cleaner is designed for maximum portability. While lightweight, it is short, so the area it can clean while sitting down is limited. Therefore, it is best used for cleaning small areas like desks, sofas, and cars.

[0007] Stick vacuums can be used while standing, allowing for cleaning without bending over. This makes them convenient for moving around and cleaning a wide area. While handheld vacuums are used to clean narrow spaces, stick vacuums can handle wider spaces and even high, inaccessible areas. In recent years, stick vacuums have been offered in modular configurations, allowing users to change the type of cleaner to suit various applications.

[0008] However, in the case of conventional handheld vacuum cleaners and stick vacuum cleaners, since the dust box for storing collected dust has a small capacity, it is troublesome for the user to empty the dust box every time.

[0009] Furthermore, when the dust box is emptied, dust scatters and adversely affects the health of the user.

[0010] In addition, if the residual dust in the dust box is not removed, there is a problem that the suction power of the vacuum cleaner is reduced.

[0011] Furthermore, if the dust remaining in the dust box is not removed, there is a problem that the remaining dust may cause an odor.

[0012] As a conventional patent document, Korean Laid-Open Patent Publication No. 10-2022-0086482 discloses a vacuum cleaner base station capable of automatically emptying a dust box of a vacuum cleaner when the vacuum cleaner is coupled to the vacuum cleaner base station.

[0013] The above-mentioned prior art patent document is structured as follows: when the vacuum cleaner is coupled to the vacuum cleaner base station, the dust box discharge cover of the vacuum cleaner is opened, and the dust passage hole is opened to connect the internal space of the dust box with the flow path of the vacuum cleaner base station.

[0014] However, in the case of the above-mentioned vacuum cleaner base station, in order to precisely rotate the link, a component such as an encoder capable of detecting the rotation of the motor shaft is also required.

[0015] Furthermore, since the two links are rotatably fixedly coupled to each other, it is inconvenient to assemble a portion of the links to the housing or to replace a portion of the links due to damage.

[0016] In addition, in the case of the above-mentioned vacuum cleaner base station, a motor and a sensor are separately provided to fix the dust box, and it takes time to operate them, which increases the number of components as a whole and increases the total time required for dust collection. Summary of the Invention

[0017] Technical issues

[0018] The present invention is developed to improve the problems existing in the previous vacuum cleaner base stations, vacuum cleaner systems and control methods as mentioned above. Its purpose is to provide a vacuum cleaner base station that can remove dust in the dust box without the need for additional operation by the user, thereby providing convenience to the user.

[0019] In addition, an object of the present invention is to provide a vacuum cleaner base station that automatically controls a discharge cover of a dust box to connect or block the flow path between the interior space of the dust box and the vacuum cleaner base station when a vacuum cleaner is coupled to the vacuum cleaner base station.

[0020] Another object of the present invention is to provide a vacuum cleaner base station capable of precisely operating a motor and controlling a discharge cover without using an encoder or the like.

[0021] Another object of the present invention is to provide a vacuum cleaner base station that can simplify the process from the time a vacuum cleaner is coupled to the vacuum cleaner base station until a dust collection motor is activated, thereby reducing the total dust collection time.

[0022] Means of solving problems

[0023] In order to achieve the above-mentioned objectives, the vacuum cleaner base station of the present invention includes: a shell; a coupling part, which is configured on the above-mentioned shell, and at least a part of the dust box of the vacuum cleaner is coupled to the coupling part; a dust box cover control unit, which opens and closes the discharge cover of the above-mentioned dust box; a dust collecting part, which is accommodated in the interior of the above-mentioned shell and configured on the lower side of the above-mentioned coupling part, capturing dust inside the above-mentioned dust box; and a dust collecting motor, which is accommodated in the interior of the above-mentioned shell and configured on the lower side of the above-mentioned dust collecting part, generating suction force to suck dust into the interior of the above-mentioned dust box, and the above-mentioned dust box cover control unit includes: a cover control motor; a cover control gear, which rotates according to the operation of the above-mentioned cover control motor; and a cover control frame, which is formed with gear teeth meshing with the above-mentioned cover control gear and contacts with the above-mentioned discharge cover, and the above-mentioned cover control gear is formed with a cam.

[0024] At this time, the above-mentioned cover control gear includes: a gear body; a gear portion, which is formed to protrude from the outer peripheral surface of the gear body and meshes with the gear teeth of the above-mentioned cover control frame; and a cam portion, which is formed to protrude from the outer peripheral surface of the above-mentioned gear body at a specified angle along the circumferential direction.

[0025] The cover control gear further includes a sensor plate that rotates together with the gear body and is formed in a disk shape with a larger diameter than the gear body.

[0026] The sensor plate includes a plate body and a sensing protrusion formed to protrude radially outward from an outer peripheral surface of the plate body and to contact the lid control sensor. Thus, the lid control sensor can sense the rotational position of the sensor plate in response to rotation of the lid control gear.

[0027] After being combined with the dust box, the gear portion may be engaged with the cover control frame to rotate.

[0028] The cam portion may come into contact with the cover control frame while the dust collecting motor is operating.

[0029] When coupled to the dust box, the cover control frame meshes with the gear portion and rotates, which then contacts the cam portion. Thus, the cover control frame contacts and supports the cam portion, thereby maintaining the dust passage opening. At this point, the dust collection motor operates to collect foreign matter within the dust box.

[0030] On the other hand, the cover control motor can be operated during the operation of the dust collecting motor. Thus, the discharge cover of the dust collecting box can be closed accordingly when the dust collecting motor ends its operation.

[0031] The dust box cover control unit further includes a return spring, which is combined with the cover control frame and applies a restoring force to the cover control frame.

[0032] During one rotation of the cover control gear, the cover control frame switches its rotation direction at least once.

[0033] While the cover control motor rotates in one direction, the cover control frame switches its rotation direction at least once.

[0034] Effects of the Invention

[0035] As described above, the vacuum cleaner base station, the vacuum cleaner system, and the control method thereof according to the present invention have the following effects: the user can avoid the trouble of emptying the dust box every time.

[0036] In addition, when the cleaner is coupled to the base station, the cover control frame is rotated while controlling the discharge cover, thereby connecting or blocking the flow path of the dust box and the base station.

[0037] Furthermore, since the gear having the cam is provided, the micro switch senses the position of the gear according to the rotation of the gear, thereby accurately sensing the rotation position. Therefore, the discharge cap can be accurately controlled without using an encoder or the like.

[0038] In addition, it has the following effect: when the vacuum cleaner is connected to the vacuum cleaner base station, the cover control frame is moved to open the discharge cover of the dust box and operate the dust collecting motor, and the discharge cover is closed at the same time as the operation of the dust collecting motor ends, thereby reducing the time required for dust collection in the dust box.

[0039] Furthermore, there is an effect of reducing the time required for fixing or releasing the cleaner, thereby reducing the overall operating time.

[0040] Furthermore, there is an effect that the cover control frame can be rotated in both directions even when a cover control motor that rotates only in one direction is used. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0053] The present invention is susceptible to various modifications and embodiments. Specific embodiments are illustrated in the accompanying drawings and described in detail in the detailed description. However, the present invention should not be construed as being limited to the specific embodiments, but rather as encompassing all modifications, equivalents, and alternatives within the spirit and technical scope of the present invention.

[0054] The terms used in this application are only used to illustrate specific embodiments and do not limit the present invention. Unless otherwise specified, the singular includes the plural.

[0055] Unless otherwise defined, all terms used herein, including technical and scientific terms, have the same meanings as those generally understood by those skilled in the art. Generally used, predefined terms should be interpreted as having the same meanings as those in the relevant technical literature and should not be interpreted as idealized or overly formalized unless specifically defined in this application.

[0056] Figure 1 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 is disclosed. Figure 5 A schematic diagram of the structure of a vacuum cleaner system according to an embodiment of the present invention is disclosed.

[0057] Reference Figure 1 and Figure 5 , a vacuum cleaner system 10 according to an embodiment of the present specification may include a vacuum cleaner base station 100 and a vacuum cleaner 200 .

[0058] The cleaner system 10 may include a cleaner base station 100. The cleaner 200 may be coupled to the cleaner base station 100. Specifically, the main body of the cleaner 200 may be coupled to the side of the cleaner base station 100. The cleaner base station 100 may remove dust from the dust box 220 of the cleaner 200.

[0059] on the other hand, Figure 2 and Figure 3 Disclosed are diagrams for explaining a vacuum cleaner in a vacuum cleaner system according to an embodiment of the present invention. Figure 4 Disclosed are diagrams for explaining the lower surface of the dust box of the vacuum cleaner according to the embodiment of the present invention.

[0060] First, refer to Figures 1 to 5 , the structure of the vacuum cleaner 200 is described as follows.

[0061] The vacuum cleaner 200 may represent a vacuum cleaner that is manually operated by a user. For example, the vacuum cleaner 200 may represent a handheld vacuum cleaner or a stick vacuum cleaner.

[0062] The vacuum cleaner 200 may be placed on the vacuum cleaner base station 100. The vacuum cleaner 200 may be supported by the vacuum cleaner base station 100. The vacuum cleaner 200 may be coupled to the vacuum cleaner base station 100.

[0063] On the other hand, in one embodiment of the present invention, the direction of the cleaner 200 is defined based on the bottom surface (lower surface) of the dust box 220 and the battery case 230 placed on the ground.

[0064] In this case, the front may refer to the direction in which the suction unit 212 is configured with respect to the suction motor 214, and the rear may refer to the direction in which the handle 216 is configured with respect to the suction motor 214. Furthermore, with respect to the suction unit 212 viewed from the suction motor 214, the direction configured to the right may be referred to as the right side, and the direction configured to the left may be referred to as the left side. Furthermore, in one embodiment of the present invention, with respect to the bottom surface (lower surface) of the dust box 220 and the battery housing 230 placed on the ground as the reference, the upper side and the lower side may be defined along a direction perpendicular to the ground.

[0065] The cleaner 200 may include a main body 210 . The main body 210 may include a main body housing 211 , a suction unit 212 , a dust separation unit 213 , a suction motor 214 , an air discharge cover 215 , a handle 216 , and an operation unit 218 .

[0066] The main body housing 211 may constitute the exterior of the vacuum cleaner 200. The main body housing 211 may provide a space for accommodating the suction motor 214 and a filter (not shown). The main body housing 211 may be formed in a cylindrical shape.

[0067] 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 referred to as "suction flow path") through which air containing dust may flow.

[0068] On the other hand, in this embodiment, an imaginary line may be formed that passes through the interior of the cylindrical suction portion 212 .

[0069] The dust separator 213 may be in communication with the suction unit 212. The dust separator 213 may separate dust sucked into the interior by the suction unit 212. The interior space of the dust separator 213 may be in communication with the interior space of the dust box 220.

[0070] For example, the dust separator 213 may include at least one cyclone separator capable of separating dust through a cyclonic flow. Furthermore, the space within the dust separator 213 may be connected to the aforementioned intake flow path. Therefore, air and dust drawn in through the intake portion 212 flow in a spiral along the inner circumferential surface of the dust separator 213. Consequently, a cyclonic flow may be generated within the interior of the dust separator 213.

[0071] The dust separator 213 is communicated with the suction unit 212 and is a structure that applies the principle of a dust collector that uses centrifugal force to separate dust sucked into the main body 210 through the suction unit 212 .

[0072] The dust separator 213 may further include a secondary cyclone separator to further separate dust from the air exhausted from the cyclone separator. In this case, the secondary cyclone separator is located inside the cyclone separator to minimize the size of the dust separator. The secondary cyclone separator may include multiple cyclone separator bodies arranged in parallel. The air exhausted from the cyclone separator may be divided and pass through the multiple cyclone separator bodies.

[0073] At this time, the axis of the cyclone flow of the secondary cyclone separator can also extend along the up and down directions, and the axis of the cyclone flow of the cyclone separator and the axis of the cyclone flow of the secondary cyclone separator can form a coaxial axis along the up and down directions, which can be collectively referred to as the axis of the cyclone flow of the dust separation part 213.

[0074] The suction motor 214 can generate suction force to inhale air. The suction motor 214 can be housed in the main body housing 211. The suction motor 214 can generate suction force by rotating. As an example, the suction motor 214 can be formed similar to a cylindrical shape.

[0075] On the other hand, in this embodiment, a virtual suction motor axis line may be formed by extending the rotation axis of the suction motor 214 .

[0076] The air outlet cover 215 may be disposed on one side in the axial direction of the main body housing 211. A filter for filtering air may be housed in the air outlet cover 215. For example, a high-efficiency particulate air filter (HEPA filter) may be housed in the air outlet cover 215.

[0077] An air outlet for discharging air sucked in by the suction force of the suction motor 214 may be formed at the air discharge cover 215 .

[0078] An air guide may be provided on the air outlet cover 215. The air guide guides the flow of air discharged through the air outlet.

[0079] The user can grip the handle 216. The handle 216 can be positioned behind the suction motor 214. For example, the handle 216 can be formed in a shape similar to a cylinder. Alternatively, the handle 216 can be formed in a curved cylindrical shape. The handle 216 can be positioned at a predetermined angle relative to the main housing 211, the suction motor 214, or the dust separator 213.

[0080] The handle 216 may include: a holding portion, which is formed in a columnar shape for the user to hold; a first extension portion, which is connected to one side end portion of the holding portion in the longitudinal direction (axial direction) and extends toward the suction motor 214; and a second extension portion, which is connected to the other side end portion of the holding portion in the longitudinal direction (axial direction) and extends toward the dust box 220.

[0081] On the other hand, in this embodiment, a virtual gripping portion penetration line extending along the longitudinal direction of the gripping portion (axial direction of the column) and penetrating the gripping portion may be formed.

[0082] As an example, the grip portion through-line may be an imaginary line formed inside the cylindrical handle 216 and may be an imaginary line formed parallel to at least a portion of the outer surface (outer peripheral surface) of the grip portion.

[0083] The upper surface of the handle 216 forms a part of the outer appearance of the upper surface of the cleaner 200. Thus, when the user grips the handle 216, it is possible to prevent one structure of the cleaner 200 from coming into contact with the user's arm.

[0084] 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.

[0085] The second extension portion extends from the grip portion toward the dust box 220. At least a portion of the second extension portion may extend in a horizontal direction.

[0086] The operating portion 218 may be provided on the handle 216. The operating portion 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 of the cleaner 200 through the operating portion 218.

[0087] The cleaner 200 may include a dust box 220. The dust box 220 may be in communication with the dust separation unit 213. The dust box 220 may store dust separated from the dust separation unit 213.

[0088] The dust box 220 may include a dust box body 221 , a discharge cover 222 , a dust box compression rod 223 , and a compression member (not shown).

[0089] The dust box body 221 may provide a space capable of storing dust separated from the dust separator 213. As an example, the dust box body 221 may be formed in a shape similar to a cylinder.

[0090] On the other hand, in this embodiment, an imaginary dust box through line may be formed that passes through the interior (internal space) of the dust box body 221 and extends along the length direction of the dust box body 221 (indicating the axial direction of the cylindrical dust box body 221).

[0091] A portion of the lower surface (bottom surface) of the dust box body 221 may be open. In addition, a lower surface extension portion 221a may be formed on the lower surface (bottom surface) of the dust box body 221. The lower surface extension portion 221a may block a portion of the lower surface of the dust box body 221.

[0092] The dust box 220 may include a discharge cover 222. The discharge cover 222 may be disposed on a lower surface of the dust box 220.

[0093] The discharge cover 222 may be provided to open and close one end portion in the length direction of the dust box body 221. Specifically, the discharge cover 222 may selectively open and close the lower portion of the dust box 220 that is open downward.

[0094] The discharge cover 222 may include a cover body 222a and a hinge portion 222b. The cover body 222a may block a portion of the lower surface of the dust box body 221. The cover body 222a rotates downward with the hinge portion 222b as a reference. The hinge portion 222b may be arranged adjacent to the battery case 230. The hinge portion 222b may include a torsion spring 222d. Therefore, when the discharge cover 222 is separated from the dust box body 221, the elastic force of the torsion spring 222d supports the cover body 222a in a state of rotating at least a predetermined angle about the hinge portion 222b as an axis at the dust box body 221.

[0095] The discharge cover 222 can be coupled to the dust box 220 via a hook connection. Alternatively, the discharge cover 222 can be separated from the dust box 220 via a coupling rod 222c. The coupling rod 222c can be positioned in front of the dust box. Specifically, the coupling rod 222c can be positioned on the outer surface of the front side of the dust box 220. When an external force is applied, the coupling rod 222c elastically deforms a hook extending from the cover body 222a, thereby releasing the hook connection between the cover body 222a and the dust box body 221.

[0096] When the discharge cover 222 is closed, the lower surface of the dust box 220 can be blocked (sealed) by the discharge cover 222 and the lower surface extension portion 221 a .

[0097] The dust box 220 may include a dust box compression rod 223 (see Figure 3 ). The dust box compression rod 223 can be arranged on the outside of the dust box 220 or the dust separation part 213. The dust box compression rod 223 can be arranged on the outside of the dust box 220 or the dust separation part 213 so as to be movable up and down. The dust box compression rod 223 can be connected to a compression member (not shown). When the dust box compression rod 223 is moved downward by an external force, the compression member (not shown) also moves downward together. Thereby, convenience for the user can be provided. The compression member (not shown) and the dust box compression rod 223 are returned to their original positions by an elastic member (not shown). Specifically, when the external force applied to the dust box compression rod 223 is removed, the elastic member can cause the dust box compression rod 223 and the compression member (not shown) to move upward.

[0098] A compression member (not shown) can be disposed inside the dust box body 221. The compression member can move within the internal space of the dust box body 221. Specifically, the compression member can move up and down within the dust box body 221. Thus, the compression member can compress the dust within the dust box body 221 downward. In addition, when the discharge cover 222 is separated from the dust box body 221 and the lower portion of the dust box 220 is opened, the compression member can move from the upper portion to the lower portion of the dust box 220 to remove residual dust and other foreign matter within the dust box 220. As a result, no dust remains within the dust box 220, and the suction power of the vacuum cleaner can be improved. At the same time, no dust remains within the dust box 220, and odors caused by the residual dust can be removed.

[0099] 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 bottom. The back of the battery housing 230 may be connected to the handle 216.

[0100] The battery case 230 may include a storage portion open downward. The battery 240 can be installed and removed through the storage portion of the battery case 230.

[0101] The vacuum cleaner 200 may include a battery 240 .

[0102] For example, the battery 240 can be detachably coupled to the cleaner 200. The battery 240 can be detachably coupled to the battery housing 230. As an example, the battery 240 can be inserted into the battery housing 230 from below. With such a structure, the portability of the cleaner 200 can be improved.

[0103] Alternatively, the battery 240 may be integrally provided inside the battery case 230. In this case, the lower surface of the battery 240 is not exposed to the outside.

[0104] The battery 240 can supply power to the suction motor 214 of the cleaner 200. The battery 240 can be arranged at the bottom of the handle 216. The battery 240 can be arranged behind the dust box 220.

[0105] According to an embodiment, when the battery 240 is coupled to the battery housing 230, the lower surface of the battery 240 can be exposed to the outside. When the vacuum cleaner 200 is placed on the floor, the battery 240 can be placed on the floor, thereby directly separating the battery 240 from the battery housing 230. In addition, the lower surface of the battery 240 is exposed to the outside and directly contacts the outside air, thereby improving the cooling performance of the battery 240.

[0106] On the other hand, when the battery 240 is integrally fixed to the battery case 230, the structure for detaching the battery 240 and the battery case 230 can be reduced, so the overall size of the vacuum cleaner 200 can be reduced and the weight can be reduced.

[0107] The cleaner 200 may include an extension pipe 250. The extension pipe 250 may be in communication with the dust collection 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.

[0108] The main body 210 may be connected to an extension tube 250. The main body 210 may be connected to a dust collection module 260 via the extension tube 250. The main body 210 may generate suction via the suction motor 214, and provide suction to the dust collection module 260 via the extension tube 250. External dust may flow into the main body 210 through the dust collection module 260 and the extension tube 250.

[0109] The cleaner 200 may include a suction module 260. The suction 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 suction module 260 and the extension tube 250 due to the suction force generated in the main body 210 of the cleaner 200.

[0110] Dust in the dust box 220 of the vacuum cleaner 200 is captured by gravity and the suction force of the dust collection motor 191 and collected in the dust collection unit 170 of the vacuum cleaner base station 100. This allows dust removal from the dust box without requiring additional user intervention, thus improving user convenience. Furthermore, this eliminates the need for the user to empty the dust box each time. Furthermore, emptying the dust box prevents dust from scattering.

[0111] 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 box 220 and battery housing 230 of the vacuum cleaner 200 can be arranged opposite the coupling surface 121. The outer peripheral surface of the dust box main body 221 can be coupled to the dust box 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 box 220 can be arranged parallel to the ground, and the extension tube 250 can be arranged perpendicular to the ground.

[0112] Reference Figure 1 and Figure 5 , the vacuum cleaner base station 100 of the present invention is described as follows.

[0113] The vacuum cleaner base station 100 may be equipped with a vacuum cleaner 200. The vacuum cleaner 200 may be coupled to the side of 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 box 220 of the vacuum cleaner 200.

[0114] The vacuum cleaner base station 100 may include a housing 110. The housing 110 forms the appearance of the vacuum cleaner base station 100. Specifically, the housing 110 may be formed in a column shape including at least one outer wall surface. As an example, the housing 110 may be formed in a shape similar to a quadrangular prism.

[0115] The housing 110 may have a space formed therein to accommodate the dust collecting portion 170 for storing dust and the dust suction module 190 for generating a flow force to collect dust into the dust collecting portion 170 .

[0116] The housing 110 may include a bottom surface 111 , an outer wall surface 112 , and an upper surface 113 .

[0117] The bottom surface 111 may support the lower side of the dust suction module 190 in the gravity direction. That is, the bottom surface 111 may support the lower side of the dust collecting motor 191 of the dust suction module 190.

[0118] In this case, bottom surface 111 can be placed facing the ground. Bottom surface 111 can be placed not only parallel to the ground but also tilted at a predetermined angle relative to the ground. This structure can stably support dust collection motor 191 and maintain overall weight balance when combined with vacuum cleaner 200.

[0119] On the other hand, according to an embodiment, the bottom surface 111 may further include a ground support portion to increase the area of ​​contact with the ground in order to prevent the vacuum cleaner base station 100 from falling and maintain balance. For example, the ground support portion may be formed in the form of a plate extending from the bottom surface 111, or may be formed by one or more frames protruding from the bottom surface 111 toward the ground.

[0120] The outer wall surface 112 may be a surface formed along the direction of gravity or may be a surface connected to the bottom surface 111. For example, the outer wall surface 112 may be 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 relative to the bottom surface 111.

[0121] 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.

[0122] In this embodiment, the first outer wall 112a may be disposed on the front of the vacuum cleaner base station 100. Here, the front may refer to the side of the vacuum cleaner 200 that is exposed when the vacuum cleaner 200 is coupled to the vacuum cleaner base station 100. Therefore, the first outer wall 112a may form the front appearance of the vacuum cleaner base station 100.

[0123] On the other hand, in order to help understand the present embodiment, the directions are defined as follows: In the present embodiment, the directions may be defined in a state where the cleaner 200 is placed on the cleaner base station 100 .

[0124] 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.

[0125] 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 disposed can be called the front. And the direction opposite to the direction in which the suction motor 214 is disposed on the cleaner base station 100 can be called the rear.

[0126] Furthermore, based on the internal space of the housing 110, the surface opposite to the front surface can be called the back surface of the vacuum cleaner base station 100. Therefore, the back surface can refer to the direction in which the second outer wall surface 112b is formed.

[0127] Furthermore, with the interior space of the housing 110 as a reference, the left side when viewed from the front 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.

[0128] The first outer wall surface 112 a 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 in part.

[0129] The first outer wall surface 112a may have an appearance corresponding to the shape of the vacuum cleaner 200. Specifically, a coupling portion 120 may be disposed on the first outer wall surface 112a. With this structure, the vacuum cleaner 200 can be coupled to and supported by the vacuum cleaner base station 100. The specific structure of the coupling portion 120 will be described later.

[0130] On the other hand, a structure for placing various types of dust collection modules 260 used in the vacuum cleaner 200 may be added to the first outer wall surface 112 a .

[0131] In this embodiment, the second outer wall surface 112b may be opposite the first outer wall surface 112a. In other words, the second outer wall surface 112b may be located on the back side of the vacuum cleaner base station 100. Here, the back side refers to the side opposite the side that is used to connect with the vacuum cleaner 200 or the second vacuum cleaner 300. Therefore, the second outer wall surface 112b may form the outer appearance of the back side of the vacuum cleaner base station 100.

[0132] As an example, the second outer wall surface 112b may be formed in a flat shape. With such a structure, the vacuum cleaner base station 100 can be closely attached to the indoor wall and stably supported.

[0133] As another example, a structure for placing various types of dust collection modules 260 used in the vacuum cleaner 200 may be added to the second outer wall surface 112 b.

[0134] 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 vacuum cleaner 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.

[0135] 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 in part.

[0136] On the other hand, a structure for placing various types of dust collection modules 260 used in the cleaner 200 may be added to the third outer wall surface 112 c or the fourth outer wall surface 112 d .

[0137] The upper surface 113 may form the upper appearance of the vacuum cleaner base station. That is, the upper surface 113 may refer to a surface that is located on the uppermost side in the gravity direction of the vacuum cleaner base station and is exposed to the outside.

[0138] For reference, in this embodiment, the upper side and the lower side may respectively refer to the upper side and the lower side formed along the gravity direction (the direction perpendicular to the ground) when the vacuum cleaner base station 100 is set on the ground.

[0139] In this case, the upper surface 113 may be arranged parallel to the ground, or may be arranged inclined at a predetermined angle with respect to the ground.

[0140] A display unit 410 may be provided on the upper surface 113. For example, the display unit 410 may display the status of the cleaner base station 100, the status of the cleaner 200, and other information such as the cleaning progress and a map of the cleaning area.

[0141] On the other hand, according to an embodiment, the upper surface 113 may be configured to be detachable from the outer wall surface 112. In this case, when the upper surface 113 is detached, the battery detached from the 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 can be provided.

[0142] On the other hand, a connecting rod stopper 115 for limiting the rotation path of the connecting rod 143 described later may be formed on the housing 110. Specifically, a space (flow path 180) for the air flowing in from the dust box 220 may be formed inside the housing 110, and the connecting rod stopper 115 may be protrudingly formed on the inner wall surface of the duct forming the flow path 180.

[0143] At this time, the connecting rod limiter 115 can be disposed within the rotation radius of the first connecting rod 1431 .

[0144] Therefore, the first link 1431 contacts the link stopper 115, thereby limiting the rotation range of the first link 1431. Specifically, the link stopper 115 may include a first link stopper 115a that provides a lower rotation limit for the first link 1431 and a second link stopper 115b that provides an upper rotation limit for the first link 1431. With this structure, the first link 1431 can rotate between the first link stopper 115a and the second link stopper 115b.

[0145] Therefore, according to the present invention, even without using an encoder or the like, the link 143 can be moved to a correct position.

Figures 8 to 11 Disclosed are diagrams for explaining the relationship between a vacuum cleaner and a door unit in a vacuum cleaner base station according to an embodiment of the present invention.

[0147] Reference Figure 5 and Figure 6 The coupling portion 120 of the vacuum cleaner base station 100 of the present invention is described as follows.

[0148] The vacuum cleaner base station 100 may include a coupling portion 120 for coupling with the vacuum cleaner 200. Specifically, the coupling portion 120 may be disposed on the first outer wall surface 112a and coupled with the main body 210, the dust box 220 and the battery housing 230 of the vacuum cleaner 200.

[0149] 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 step with the first outer wall surface 112a.

[0150] The vacuum cleaner 200 can be stored on the coupling surface 121. As an example, the coupling surface 121 can be opposite to the lower surface of the dust box 220 and the battery housing 230 of the vacuum cleaner 200. Here, the lower surface can refer to the surface facing the ground when the user uses the vacuum cleaner 200 or places the vacuum cleaner 200 on the ground.

[0151] As an example, the coupling surface 121 may form a right angle with the ground. 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.

[0152] As another example, the coupling surface 121 may be arranged to be inclined at a predetermined angle to the ground. Thus, when the cleaner 200 is coupled to the coupling surface 121 , the cleaner base station 100 can be stably supported.

[0153] A dust hole 121a may be formed on the joint surface 121 to allow air outside the housing 110 to flow into the interior. The dust hole 121a is formed to correspond to the shape of the dust box 220, allowing dust from the dust box 220 to flow into the dust collection unit 170. The dust hole 121a may be formed to correspond to the shape of the discharge cover 222 of the dust box 220. The dust hole 121a may be formed to communicate with the flow path 180, which will be described later.

[0154] The coupling portion 120 may include a dust box guide surface 122 . The dust box guide surface 122 may be disposed on the first outer wall surface 112 a . The dust box guide surface 122 may be connected to the first outer wall surface 112 a . Furthermore, the dust box guide surface 122 may be connected to the coupling surface 121 .

[0155] The dust box guide surface 122 may be formed in a shape corresponding to the outer surface of the dust box 220 . A front outer surface of the dust box 220 is coupled to the dust box guide surface 122 .

[0156] On the other hand, a protrusion moving hole 122a may be formed on the dust box guide surface 122, and the pressing protrusion 151 described later may be able to move linearly along the protrusion moving hole 122a. In addition, a gear box 155 for accommodating the gears and the like of the cover opening unit 150 described later may be provided on the lower side of the dust box guide surface 122 in the gravity direction. At this time, a guide space 122b for the pressing protrusion 151 to move may be formed between the dust box guide surface 122 and the lower surface and the upper surface of the gear box 155. In addition, the above-mentioned guide space 122b can be connected to the first flow path 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 181a can form a bypass flow path (refer to Figure 11 With this structure, when the dust collecting motor 191 is running with the dust collecting box 220 coupled to the coupling portion 120, dust and the like remaining in the dust collecting box 220 and the dust collecting box guide surface 122 can be sucked in through the bypass flow path.

[0157] 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 disposed 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.

[0158] 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 box guide surface 122. This allows for stable storage of the vacuum cleaner 200.

[0159] 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.

[0160] 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 the coupling of the vacuum cleaner 200.

[0161] Alternatively, the combined sensor 125 may include a non-contact sensor. For example, the combined sensor 125 may include an infrared sensor. In this case, the combined sensor 125 may be disposed on the sidewall 124. Therefore, when the dust box 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 box 220 or the main body 210.

[0162] The coupling sensor 125 may be opposite to the dust box 220 or the battery housing 230 of the cleaner 200 .

[0163] The coupling sensor 125 may be a unit for determining whether power is applied to the battery 240 of the cleaner 200 and determining whether to couple with the cleaner 200 .

[0164] The coupling portion 120 may include a suction guide surface 126. The suction guide surface 126 may be disposed on the first outer wall surface 112a. The suction guide surface 126 may be connected to the dust box guide surface 122. The suction portion 212 may be coupled to the suction guide surface 126. The suction guide surface 126 may be shaped to correspond to the shape of the suction portion 212.

[0165] 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.

[0166] With this structure, when the user couples the vacuum cleaner 200 to the coupling portion 120 of the vacuum cleaner base station 100, the dust box guide surface 122, the guide protrusion 123, and the suction unit guide surface 126 allow the main body 210 of the vacuum cleaner 200 to be stably positioned on the coupling portion 120. This facilitates coupling the dust box 220 and the battery housing 230 of the vacuum cleaner 200 to the coupling surface 121.

[0167] Reference Figure 5 、 Figure 7 and Figure 13 , the fixing unit 130 of the present invention is described as follows.

[0168] 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 be fixed to the vacuum cleaner 200 coupled to the dust box guide surface 122. Specifically, the fixing unit 130 may fix the dust box 220 of the vacuum cleaner 200 coupled to the dust box guide surface 122.

[0169] The fixing unit 130 may include a fixing member 131 for fixing the dust box 220 and the battery housing 230 of the cleaner 200 .

[0170] The fixing member 131 can be disposed on the side wall 124 of the coupling portion 120 and reciprocate on the side wall 124 to fix the dust box 220. Specifically, the fixing member 131 can be received in the fixing member access hole 127.

[0171] The fixing members 131 may be disposed on both sides of the coupling portion 120. As an example, two fixing members 131 are disposed symmetrically to form a pair around the coupling surface 121.

[0172] When an external force is applied, the fixing member 131 moves toward the dust box 220 to fix the dust box. In addition, when the applied external force is released, the fixing member 131 for fixing the dust box 220 moves away from the dust box 220.

[0173] 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.

[0174] 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 is moved by receiving the suction force through a flow path such as a hose.

[0175] On the other hand, the fixing unit 130 may further include a fixing seal 136. When the cleaner 200 is coupled to the fixing seal 136, the dust box 220 is airtightly arranged on the dust box guide surface 122. With this structure, when the dust box 220 of the cleaner 200 is coupled, the weight of the cleaner 200 pressurizes the fixing seal 136, thereby sealing the dust box 220 and the dust box guide surface 122.

[0176] This prevents residual dust from remaining in the dust box, thereby improving the suction power of the vacuum cleaner. At the same time, it prevents residual dust from remaining in the dust box, thereby removing odors caused by the residual dust.

[0177] Reference Figure 5 、 Figures 8 to 11 and Figure 13 The dust box cover control unit 500 of the present invention is described as follows.

[0178] The vacuum cleaner base station 100 of the present invention may include a dust box cover control unit 500. The dust box cover control unit 500 may be configured to open and close at least a portion of the dust passage hole 121a.

[0179] On the other hand, the conventional dust box cover control unit uses a bidirectionally rotatable motor, and can change the rotation direction and the output of the motor in accordance with the control operation of the control unit.

[0180] However, as described above, when a bidirectionally rotatable motor is used, a high output and precise control are required, which requires additional components such as an encoder, increases the risk of failure, and increases the overall control time.

[0181] To solve this problem, the dust box cover control unit 500 of the present invention may be configured to rotate the motor in only one direction.

[0182] Specifically, the dust box cover control unit 500 may include a cover control gear 510 , a cover control motor 520 , a cover control frame 530 , a cover control sensor 540 , and a return spring 550 .

[0183] The cover control gear 510 is coupled to the cover control motor 520 and may rotate according to the operation of the cover control motor 520 .

[0184] The lid control gear 510 may connect the lid control frame 530 and the lid control motor 520 , and rotate using power generated by the lid control motor 520 to rotate the lid control frame 530 .

[0185] The lid control gear 510 includes a gear body 511 , a gear portion 512 , a cam portion 513 , and a sensor plate 514 .

[0186] The gear body 511 may be coupled to the lid control motor 520 and receive a rotational force of the lid control motor 520 to rotate.

[0187] For example, the gear body 511 may be formed in a circular block shape, with the shaft of the lid control motor 520 coupled to the center. Specifically, a hole may be formed at the rotation center of the circular gear body 511, into which the shaft of the lid control motor 520 is inserted and coupled. In this case, the gear body 511 may be splined to the shaft of the lid control motor 520.

[0188] On the other hand, a gear portion 512 and a cam portion 513 may be formed on the outer peripheral surface of the gear body 511 .

[0189] The gear portion 512 is formed to protrude from the outer circumferential surface of the gear body 511 and can mesh with gear teeth of the cover control frame 530 .

[0190] For example, the gear portion 512 may include a plurality of gear teeth. The gear teeth of the gear portion 512 may be formed to protrude from the outer circumference of the gear body 511 at predetermined intervals. The gear teeth of the gear portion 512 may mesh with the gear teeth of the cover control frame 530.

[0191] With such a structure, when the gear body 511 rotates, the gear portion 512 may rotate together and transmit a rotational force to the cover control frame 530 .

[0192] The cam portion 513 is formed to protrude from the outer peripheral surface of the gear body 511 at a predetermined angle along the circumferential direction.

[0193] The cam portion 513 may be formed to protrude from the outer circumferential surface of the gear body 511 and to protrude by a predetermined length along the circumferential direction. In other words, the cam portion 513 may be formed to have a radius larger than that of the gear body 511 with respect to the rotation center of the cover control gear 510.

[0194] On the other hand, the length from the rotation center of the lid control gear 510 to the cam portion 513 can be the same as the length from the rotation center of the lid control gear 510 to the outer end of the gear portion 512. In other words, the length of the cam portion 513 protruding from the outer circumference of the gear body 511 can be the same as the length of the gear portion 512 protruding from the outer circumference of the gear body 511. With this structure, the lid control frame 530 meshes with the gear portion 512, rotates, and then contacts the cam portion 513 to maintain its position.

[0195] The sensing plate 514 rotates together with the gear body 511 and can sense the position of the gear body 511 through the cover control sensor 540 .

[0196] The sensing plate 514 is coupled to one axial side of the gear body 511 and is thereby rotatable together with the gear body 511. That is, the sensing plate 514 is rotatable coaxially with the gear body 511.

[0197] The sensing plate 514 may sense a position through the cover control sensor 540 according to the rotation.

[0198] For example, the sensing plate 514 includes a plate body 514 a and a sensing protrusion 514 b .

[0199] The plate body 514a may be formed in a disc shape. In this case, the plate body 514a may be formed in a shape having a larger radius than the gear body 511. With this structure, the plate body 514a reinforces the gear body 511, thereby having the effect of improving the durability of the gear body 511.

[0200] The sensing protrusion 514 b is formed to protrude radially outward from the outer peripheral surface of the plate body 514 a so as to be in contact with the lid control sensor 540 .

[0201] The sensing protrusions 514 b include a first sensing protrusion 514 ba , a second sensing protrusion 514 bb , and a third sensing protrusion 514 bc . The first sensing protrusion 514 ba , the second sensing protrusion 514 bb , and the third sensing protrusion 514 bc may be arranged to correspond to the positions of the gear portion 512 and the cam portion 513 .

[0202] For example, when the gear teeth of the gear portion 512 mesh with the gear teeth of the driven gear 532, the first sensing protrusion 514ba may be arranged in contact with the lid control sensor 540. Furthermore, when the gear teeth of the cam portion 513 and the driven gear 532 begin to contact, the second sensing protrusion 514bb may be arranged in contact with the lid control sensor 540. Furthermore, while the gear teeth of the cam portion 513 and the driven gear 532 maintain contact, the third sensing protrusion 514bc may be arranged in contact with the lid control sensor 540.

[0203] With this structure, when the lid control gear 510 rotates and transmits power to the driven gear 532 , the lid control sensor 540 can sense the sensing protrusion 514 b and the control unit 400 can sense the position of the lid control frame 530 .

[0204] The cover control motor 520 may provide power to rotate the cover control frame 530 .

[0205] The lid control motor 520 converts electrical energy into rotational energy. Specifically, when power is applied to the lid control motor 520, the shaft of the lid control motor 520 rotates. At this point, the shaft of the lid control motor 520 engages with the lid control gear 510, transmitting rotational force to the lid control gear 510.

[0206] For example, the cover control motor 520 may be a synchronous motor, but is not limited thereto. In the case of a synchronous motor, the motor rotates in synchronization with the power frequency to maintain a stable rotation speed.

[0207] For example, the cover control motor 520 of the present invention may also rotate in only one direction. With such a structure, additional components for switching the rotation direction can be reduced.

[0208] The cover control frame 530 is hinge-coupled to the housing 110 and can open and close the dust passing hole 121 a.

[0209] Specifically, when the cleaner 200 is coupled to the cleaner base station 100 and the discharge cover 222 is separated from the dust box body 210, the cover control frame 530 may contact the discharge cover 222. Also, according to the rotation of the cover control frame 530, the discharge cover 222 may rotate in conjunction with the cover control frame 530.

[0210] The cover control frame 530 may include a frame body 531 , a driven gear 532 , and a return rod 533 .

[0211] The frame body 531 can be formed into a shape that blocks at least a portion of the dust-passing hole 121a. As one example, the frame body 531 can be formed in a shape similar to a disk. As another example, the frame body 531 can be formed in a shape similar to a square bar.

[0212] On the other hand, when the cleaner 200 is coupled to the cleaner base station 100, the frame body 531 may contact the discharge cover 222. At this time, according to an embodiment, the lower end of the frame body 531 may be formed to be bent at a predetermined angle toward the discharge cover 222.

[0213] With this structure, the frame body 531 can rotate while the discharge cover 222 is coupled to the dust box body 221. In particular, when the lower end of the frame body 531 is bent, when the discharge cover 222 is closed, the discharge cover 222 can be pressed with greater force, which can increase the force with which the discharge cover 222 is coupled to the dust box body 221.

[0214] Based on the state in which the frame body 531 blocks the dust passage hole 121 a , a hinge portion may be disposed on the upper side of the frame body 531 , and a driven gear 532 may be disposed on the lower side of the frame body 531 .

[0215] The hinge portion of the frame body 531 may be disposed at an upper end portion of the frame body 531 and hingedly coupled to the housing 110 .

[0216] The driven gear 532 is connected to the frame body 531 and rotates together with the hinge portion.

[0217] For example, based on the state in which the frame body 531 blocks the dust passage hole 121 a , the driven gear 532 may extend upward and rearward from the frame body 531 .

[0218] In addition, a plurality of gear teeth may be formed on an upper portion of the driven gear 532 to engage with the lid control gear 510. Therefore, the driven gear 532 may rotate according to the rotation of the lid control gear 510 and transmit the rotational force to the frame body 531.

[0219] The return rod 533 is connected to the frame body 531 and can rotate together with the hinge portion.

[0220] For example, based on the state in which the frame body 531 blocks the dust passage hole 121a, the return rod 533 may be a frame shape extending from the frame body 531 toward the rear upper side.

[0221] Alternatively, according to an embodiment, the return lever 533 can be configured to bend at least once. This structure mitigates the impact of a sudden force applied by the lid control gear 510 or the return spring 550 by bending. Consequently, the return lever 533 of the present invention can prevent damage to the lid control frame 530.

[0222] Furthermore, the upper portion of the return rod 533 may be coupled to the return spring 550. For example, a hole for coupling with one end portion of the return spring 550 may be formed in the upper portion of the return rod 533. Therefore, when no external force is applied to the driven gear 532 via the cover control gear 510, the restoring force of the return spring 550 is applied to the return rod 533, thereby rotating the frame body 531.

[0223] With such a structure, when the cover control motor 520 operates, the cover control gear 510 rotates, and the cover control frame 530 can periodically open and close at least a portion of the dust passage hole 121 a.

[0224] When the cover control gear 510 rotates due to the operation of the cover control motor 520, the frame body 531 rotates and moves toward the outside of the cleaner base station 100 with the hinge as the axis, blocking at least a portion of the dust passage hole 121a.

[0225] When the cover control gear 510 rotates further, the frame body 531 rotates about the hinge portion toward the inside of the cleaner base station 100 and opens the dust passage hole 121 a , thereby connecting the interior space of the dust box 220 to the flow path 180 .

[0226] The lid control sensor 540 may be disposed inside the housing 110 and may sense a position of the lid control frame 530 .

[0227] For example, the lid control sensor 540 is disposed at a position where it can contact the sensing protrusion 514 b . Therefore, when the lid control gear 510 rotates and contacts the sensing protrusion 514 b , the lid control sensor 540 can sense this.

[0228] Therefore, when the cover control gear 510 rotates and the first sensing protrusion 514ba contacts the cover control sensor 540, it can be sensed that the cover control frame 530 starts to open. For example, while the first sensing protrusion 514ba contacts the cover control sensor 540, the control unit 400 can sense that the cover control frame 530 rotates after maintaining its position for a predetermined time and that the discharge cover 222 is opened.

[0229] Furthermore, when the second sensing protrusion 514bb contacts the lid control sensor 540 as the lid control gear 510 rotates, the lid control sensor 540 can sense that the lid control frame 530 is opened. In other words, when the second sensing protrusion 514bb contacts the lid control sensor 540, the controller 400 can sense that the discharge cover 222 is opened and the interior space of the dust box 220 is in communication with the flow path 180.

[0230] Furthermore, when the third sensing protrusion 514bc contacts the lid control sensor 540 as the lid control gear 510 rotates, the lid control sensor 540 can sense that the lid control frame 530 remains open. In other words, when the third sensing protrusion 514bc contacts the lid control sensor 540, the control unit 400 can sense that the interior space of the dust box 220 and the flow path 180 remain connected.

[0231] The lid control sensor 540 may further include a contact sensor. As an example, the lid control sensor 540 may include a micro switch.

[0232] The return spring 550 may be coupled to the cover control frame 530 and apply a restoring force to the cover control frame 530 .

[0233] For example, the return spring 550 may be a coil spring, one end portion in the length direction may be coupled to the return rod 533 of the cover control frame 530 , and the other end portion in the length direction may be coupled to the housing 110 .

[0234] Therefore, when the cover control frame 530 rotates, the return spring 550 may apply a restoring force to return the cover control frame 530 to an original position.

[0235] On the other hand, refer to Figures 9 to 11 The operation process of the dust box cover control unit 500 according to the embodiment of the present invention is described as follows.

[0236] First, before the cover control frame 530 is opened, the gear teeth of the driven gear 532 are not in contact with the gear portion 512 or the cam portion 513. Therefore, the return rod 533 is pulled downward by the elastic support force of the return spring 550, and the frame body 531 is in a state of blocking at least a portion of the dust passage hole 121a (see FIG. Figure 9 ).

[0237] That is, when the cleaner 200 is coupled to the cleaner base station 100 , the frame body 531 presses the discharge cover 222 toward the dust box body 221 , so that the internal space of the dust box 220 and the first flow path 181 are blocked by the discharge cover 222 .

[0238] At this time, the cap control sensor 540 may sense the first sensing protrusion 514ba.

[0239] Then, when the lid control motor 520 is operated to rotate the lid control gear 510, the gear teeth of the gear portion 512 and the gear teeth of the driven gear 532 can mesh with each other and rotate. Therefore, the frame body 531 rotates together with the driven gear 532, and the frame body 531 rotates toward the inside of the vacuum cleaner base station 100 with the hinge portion as the axis.

[0240] At this time, when the coupling rod 222c of the dust box 220 is pressurized by external force, the discharge cover 222 is separated from the dust box body 221, and the discharge cover 222 rotates together with the frame body 531 due to the elastic force of the torsion spring 222d. In addition, the discharge cover 222 can rotate in conjunction with the frame body 531.

[0241] On the other hand, according to an embodiment, a stopper capable of limiting the rotation position of the frame body 531 may be formed inside the cleaner base station 100. In this case, the frame body 531 rotates to a specified position and then maintains the position.

[0242] At this time, the cap control sensor 540 may sense the second sensing protrusion 514bb.

[0243] When the lid control motor 520 is operated, causing the lid control gear 510 to further rotate, the gear teeth of the cam portion 513 and the driven gear 532 may contact each other. In this case, the cam portion 513 can continue to rotate, while the driven gear 532 can maintain its position while in contact with the cam portion 513. Therefore, the position of the frame body 531 can be maintained.

[0244] In this state, the discharge cover 222 is still in the open state, and the internal space of the dust box 220 and the first flow path 181 are still in the communication state (see Figure 10 ).

[0245] Also, the cover control sensor 540 may sense the third sensing protrusion 514bc.

[0246] On the other hand, the dust collecting motor 191 can be operated while the interior space of the dust collecting box 220 is connected to the first flow path 181. With such a structure, foreign matter stored in the dust collecting box 220 flows along the flow path portion 180 and is thus captured by the dust collecting portion 170.

[0247] Then, when the cap control motor 520 is operated to further rotate the cap control gear 510 , the contact between the cam portion 513 and the gear teeth of the driven gear 532 can be released.

[0248] At this time, the return rod 533 is pulled downward by the restoring force of the return spring 550 , and the frame body 531 rotates inside the cleaner base station 100 toward the dust passage hole 121 a with the hinge portion as an axis.

[0249] As a result, the frame body 531 and the discharge cover 222 rotate together, and the discharge cover 222 can be coupled to the dust box body 221. Therefore, the communication between the internal space of the dust box 220 and the flow path portion 180 can be cut off.

[0250] Therefore, according to the present invention, the cover control frame 530 may be periodically rotated by the operation of the cover control motor 520 .

[0251] Therefore, according to the vacuum cleaner base station 100 of the present invention, when the vacuum cleaner 200 is coupled to the vacuum cleaner base station 100, the cover control frame 530 rotates and controls the discharge cover 222 to connect or block the internal space of the dust box 220 and the flow path portion 180 of the vacuum cleaner base station.

[0252] Furthermore, the cap control gear 510 is provided with a cam shape, and the cap control sensor 540 can sense the cam and accurately sense the rotational position of the cap control gear 510 , thereby enabling accurate control of the discharge cap 222 without using an encoder or the like.

[0253] Reference Figure 5 、 Figure 12 and Figure 13 , the cover opening unit 150 of the present invention is described as follows.

[0254] The vacuum cleaner base station 100 of the present invention may include a cover opening unit 150. The cover opening unit 150 may be disposed at the coupling portion 120 and may open the discharge cover 222 of the vacuum cleaner 200.

[0255] The cover opening unit 150 may include a pressing protrusion 151 , a cover opening motor 152 , a cover opening gear 153 , a support plate 154 , and a gear box 155 .

[0256] When the pressing protrusion 151 is coupled to the cleaner 200 , the coupling rod 222 c may be moved in a pressurized manner.

[0257] The pressing protrusion 151 may be disposed on the dust box guide surface 122. Specifically, a protrusion moving hole may be formed on the dust box guide surface 122, and the pressing protrusion 151 may be exposed to the outside through the protrusion moving hole.

[0258] When combined with the vacuum cleaner 200, the pressing protrusion 151 can be configured at a position capable of pressing the coupling rod 222c. That is, the coupling rod 222c can be configured on the protrusion moving hole. In addition, the coupling rod 222c can be configured on the moving area of ​​the pressing protrusion 151.

[0259] The pressing protrusion 151 can pressurize the coupling rod 222c to cause a linear reciprocating motion. Specifically, the pressing protrusion 151 can be coupled to the gear box 155 to guide the linear motion. The pressing protrusion 151 can be coupled to the lid opening gear 153 and move together with the lid opening gear 153.

[0260] The lid opening motor 152 can provide power to move the pressing protrusion 151. Specifically, the lid opening motor 152 can rotate the motor shaft (not shown) in a forward direction or a reverse direction. Here, the forward direction may refer to the direction in which the pressing protrusion 151 presses the coupling rod 222c. Alternatively, the reverse direction may refer to the direction in which the pressing protrusion 151 pressing the coupling rod 222c returns to its original position. The forward direction may be the opposite direction to the reverse direction.

[0261] The cover-opening gear 153 can be coupled to the cover-opening motor 152 and utilize the power of the cover-opening motor 152 to move the pressing protrusion 151. Specifically, the cover-opening gear 153 can be housed inside the gear box 155. The driving gear 153a of the cover-opening gear 153 can be coupled to the motor shaft of the cover-opening motor 152 to receive power. The driven gear 153b of the cover-opening gear 153 is coupled to the pressing protrusion 151 to move the pressing protrusion 151. As an example, the driven gear 153b is formed in a rack shape and meshes with the driving gear 153a, and receives power from the driving gear 153a.

[0262] In this case, the discharge cover 222 may be equipped with a torsion spring 222d. The elastic force of the torsion spring 222d allows the discharge cover 222 to rotate beyond a predetermined angle and be supported at the rotated position. Therefore, the discharge cover 222 can be opened, allowing the dust to pass through the hole 121a and communicate with the interior of the dust box 220.

[0263] The gear box 155 may be disposed inside the housing 110 and arranged at a lower side of the coupling portion 120 in the gravity direction. The cover opening gear 153 may be accommodated inside the gear box 155 .

[0264] The gear box 155 may be provided with a cover-opening sensor 155f. In this case, the cover-opening sensor 155f may 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 infrared sensor.

[0265] The cover opening sensor 155f can be disposed on at least one of the inner or outer surfaces of the gear box 155. For example, one cover opening sensor 155f can be disposed on the inner surface of the gear box 155. In this case, the cover opening sensor 155f can sense that the pressing protrusion 151 is in the initial position.

[0266] As another example, two cover-opening sensors 155f may be disposed on the outer surface of the gear box 155. In this case, the cover-opening sensors 155f can sense the initial position of the pressing protrusion 151 and the cover-opening position.

[0267] Therefore, according to the present invention, the user can open the dust box 220 through the cover opening unit 150 without separately opening the discharge cover 222 of the first cleaner, thereby improving convenience.

[0268] In addition, 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.

[0269] On the other hand, refer to Figure 5 and Figure 13 The dust collecting unit 170 will be described below.

[0270] 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.

[0271] As an example, the dust collecting unit 170 may refer to a dust bag that collects dust sucked from the inside of the dust box 220 of the cleaner 200 by the dust collecting motor 191 .

[0272] The dust collecting portion 170 is detachably coupled to the housing 110 .

[0273] Therefore, the dust collecting portion 170 may be separated from the housing 110 and discarded, and a new dust collecting portion 170 may be coupled to the housing 110. That is, the dust collecting portion 170 may be defined as a consumable component.

[0274] The dust bag may be configured to increase in volume when suction is generated by the dust collecting motor 191 to collect dust therein.

[0275] For this purpose, the dust bag can be made of a material that allows air to pass but prevents foreign matter such as dust from passing through. As an example, the dust bag can be made of a non-woven fabric material and can have a hexahedral shape based on the increased volume.

[0276] Therefore, the user does not need to separately bundle a bag or the like that collects dust, thereby improving user convenience.

[0277] Alternatively, the dust bag may include a plastic roll (not shown). This structure, when the dust bag is sealed or joined, prevents dust or odor trapped inside the dust bag from leaking out. 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.

[0278] On the other hand, refer to Figure 5 and Figure 13 The flow path portion 180 will be described below.

[0279] The cleaner base station 100 may include a flow path unit 180 .

[0280] The flow path 180 connects the dust box 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 may refer to the space between the dust box 220 of the vacuum cleaner 200 and the dust collection unit 170. The flow path 180 may be a space formed rearward from the dust passage hole 121a, or may be a flow path that bends downward from the dust passage hole 121a to allow dust and air to flow.

[0281] Specifically, it may include a first flow path 181 and a second flow path 182. When the vacuum cleaner 200 is coupled to the vacuum cleaner base station 100 and the dust passage hole 121a is opened, the first flow path 181 is connected to the internal space of the dust collecting box 220, and the second flow path 182 enables the first flow path 181 to communicate with the internal space of the dust collecting portion 170.

[0282] For example, the first flow path 181 may be arranged substantially parallel to the axis of the suction motor 214 or an imaginary through-line passing through the dust box 220 .

[0283] 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. With such a structure, the overall volume of the cleaner base station 100 can be minimized.

[0284] The second flow path 182 extends downward from the first flow path 181 and communicates with the first flow path 181 to guide the air passing through the first flow path 181 to the dust collecting portion 170 .

[0285] The second flow path 182 may be arranged in a direction parallel to the axis C of the dust collecting motor 191. With such a structure, the degree to which the suction force of the dust collecting motor 191 is reduced in the first flow path 181 and the second flow path 182 can be minimized.

[0286] The dust in the dust box 220 of the cleaner 200 can move to the dust collecting portion 170 through the flow path portion 180 .

[0287] On the other hand, refer to Figure 5 and Figure 13 , the dust suction module 190 is described as follows.

[0288] The vacuum cleaner base station 100 may include a dust suction module 190. The dust suction module 190 may include a dust collection motor 191, a first filter (not shown), and a second filter (not shown).

[0289] The dust collecting motor 191 may be disposed below the dust collecting portion 170. The dust collecting motor 191 may generate suction force on the flow path portion 180. Thus, the dust collecting motor 191 may provide suction force capable of sucking dust into the dust box 220 of the cleaner 200.

[0290] 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.

[0291] On the other hand, in this embodiment, a virtual dust collecting motor axis C obtained by extending the rotation axis of the dust collecting motor 191 may be formed.

[0292] 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.

[0293] The second filter (not shown) may be disposed between the dust collecting motor 191 and the outer wall 112. The second filter (not shown) may be a high efficiency particulate air filter (HEPA filter).

[0294] 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.

[0295] In addition, the vacuum cleaner base station 100 may further include a side door (not shown). The side door may be disposed 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.

[0296] on the other hand, Figure 13 A block diagram for explaining the control structure in the vacuum cleaner base station according to an embodiment of the present invention is disclosed in FIG.

[0297] Reference Figure 13 , the control structure of the vacuum cleaner base station 100 of the present invention is described as follows.

[0298] The vacuum cleaner base station 100 of the embodiment of the present invention may further include a control unit 400 that controls the coupling portion 120 , the fixing unit 130 , the dust box cover control unit 500 , the cover opening unit 150 , the dust collecting portion 170 , the flow path portion 180 and the dust suction module 190 .

[0299] The control unit 400 may include a printed circuit board and components mounted on the printed circuit board.

[0300] When the coupling sensor 125 senses the coupling of the cleaner 200, the coupling sensor 125 may transmit 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 determines that the cleaner 200 is coupled to the coupling portion 120.

[0301] In addition, when power is supplied from the charging unit 128 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 .

[0302] When it is determined that the cleaner 200 is fixed to the coupling portion 120 , the control unit 400 operates the lid control motor 520 , thereby opening the lid control frame 530 of the cleaner base station 100 .

[0303] The control unit 400 receives a signal from the cover control sensor 540 that the first sensing protrusion 514ba is sensed and determines that the cover control frame 530 begins to open. At this time, according to an embodiment, it can be determined that the cover control frame 530 rotates after maintaining its position for a predetermined time and the discharge cover 222 is opened.

[0304] The control unit 400 may receive a signal from the cover control sensor 540 indicating that the second sensing protrusion 514bb has been sensed and determine that the discharge cover 222 is in the open state.

[0305] The control unit 400 receives a signal from the cover control sensor 540 that the third sensing protrusion 514bc is sensed, and thus determines that the internal space of the dust box 220 is in communication with the flow path 180. At this time, the control unit 400 may operate the dust collection motor 191.

[0306] When the guide frame 151e reaches the predetermined open position CP1, the cover-opening sensor 155f may transmit a signal indicating that the discharge cover 222 is open. The control unit 400 receives the signal from the cover-opening sensor 155f indicating that the discharge cover 222 is open and determines that the discharge cover 222 is open. If the control unit 400 determines that the discharge cover 222 is open, it may disable the operation of the cover motor 152.

[0307] The control unit 400 may drive the dust collecting motor 191 to suck in the dust inside the dust box 220 .

[0308] The control unit 400 may operate the display unit 410 to display the emptying status and charging status of the dust box of the vacuum cleaner 200 .

[0309] On the other hand, the vacuum cleaner base station 100 of the present invention may include a display unit 410 .

[0310] The display portion 410 may be provided not only on the housing 110 but also on another display device, and may be provided in a terminal including a mobile phone.

[0311] 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 voice signals and sounds. The user can easily understand the status of the currently ongoing process, the remaining time, etc. based on the information output by the display unit.

[0312] On the other hand, the vacuum cleaner base station 100 according to the embodiment of the present invention may include a memory 430. The memory 430 may include various data for driving and operating the vacuum cleaner base station 100.

[0313] 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 input by a user to operate and control the vacuum cleaner base station 100. To this end, the input unit 440 may be composed of a keyboard (keypad), a membrane key switch (dome switch), a touchpad (static pressure / static), etc. In particular, when the touchpad and the display unit 410 form a layered structure, this is referred to as a touch screen.

[0314] Figure 14 A sequence diagram for explaining a control method of the vacuum cleaner system of the present invention is shown. Figure 15 A diagram is shown for explaining the operation of each motor over time in the method for controlling the vacuum cleaner base station according to the embodiment of the present invention.

[0315] Reference Figures 5 to 15 , the control method of the vacuum cleaner base station according to an embodiment of the present invention is described as follows.

[0316] 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 dust collecting step (S30) and a cover closing step (S40).

[0317] In the coupling confirmation step ( S10 ), it is confirmed whether the cleaner 200 is coupled to the coupling portion 120 of the cleaner base station 100 .

[0318] Specifically, in the coupling confirmation step (S10), when the 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 cleaner 200 is coupled to the coupling portion 120. Alternatively, according to an embodiment, the coupling sensor 125 of a non-contact sensor type disposed on the side wall 124 may sense the presence of the dust box 220, and the coupling sensor 125 may send a signal indicating that the cleaner 200 is coupled to the coupling portion 120.

[0319] Therefore, in the coupling confirmation step ( S10 ), the control unit 400 receives a signal generated by the coupling sensor 125 and determines that the cleaner 200 is coupled to the coupling unit 120 .

[0320] Alternatively, in the coupling confirmation step ( S10 ) of the present invention, the control unit 400 senses whether the cleaner 200 is coupled to the correct position by checking whether the charging unit 128 supplies power to the battery 240 of the cleaner 200 .

[0321] In the cover opening step ( S20 ), when the dust box 220 is coupled to the cleaner base station 100 , the control unit 400 may open the discharge cover 222 of the cleaner 200 .

[0322] When receiving a signal from the fixing sensor 137 indicating that the dust box 220 is fixed, the controller 400 operates the cover opening motor 152 in a forward direction to open the discharge cover 222 .

[0323] Specifically, the control unit 400 drives the cover-opening motor 152 in the forward direction. As a result, the pressing protrusion 151 disengages from its initial position and moves to a position where it presses the coupling rod 222c. Consequently, the movement of the coupling rod 222c releases the hook connection between the discharge cover 222 and the dust box body 221. The discharge cover 222, due to the restoring force of the torsion spring 222d, rotates away from the dust box body 221, separating the cover.

[0324] On the other hand, before the pressing protrusion 151 presses the coupling rod 222 c , the cover-opening sensor 155 f may send a signal indicating that the pressing protrusion 151 is located at the initial position.

[0325] When the cover opening motor 152 is driven to move the pressing protrusion 151 to press the coupling rod 222c, the cover opening sensor 155f can send a signal indicating that the pressing protrusion 151 is separated from the initial position. The control unit 400 receives this signal and determines that the cover opening unit 150 is operating normally.

[0326] At this time, the control unit 400 measures the time after the cover opening motor 152 is driven in the forward direction or the time after the pressing protrusion 151 is separated from the initial position using a timer (not shown).

[0327] At this time, the time required for the pressing protrusion 151 to move from its initial position to press the coupling rod 222c is preset and stored in the control unit 400 based on the rotation speed of the lid-opening motor 152 and the travel distance of the pressing protrusion 151. Therefore, the control unit 400 drives the lid-opening motor 152 in the forward direction for a lid-opening time tc1 that is longer than the time required to press the coupling rod 222c. For example, the control unit 400 drives the lid-opening motor 152 in the forward direction for a period of 4 seconds to 5 seconds.

[0328] Furthermore, the control unit 400 may switch the rotation direction of the cover-opening motor 152 during a predetermined rotation direction switching time (tc2) after the cover-opening time tc1 has elapsed.

[0329] Furthermore, the control unit 400 may drive the cover opening motor 152 in the reverse direction after the rotation direction switching time tc2 has elapsed, so that the pressing protrusion 151 returns to its initial position.

[0330] The control unit 400 drives the lid-opening motor 152 until the lid-opening sensor 155f senses that the pressing protrusion 151 has returned to its initial position. At this point, the control unit 400 has preset and stored a time tc3 for the pressing protrusion 151 to return to its initial position after pressing the coupling rod 222c. Therefore, the control unit 400 drives the lid-opening motor 152 in the reverse direction during the time tc3. For example, the control unit 400 drives the lid-opening motor 152 in the reverse direction for a period of at least 4 seconds and no more than 5 seconds.

[0331] On the other hand, when receiving a signal from the cover opening sensor 155 f indicating that the pressing protrusion 151 has returned to its initial position, the control unit 400 may terminate the driving of the cover opening motor 152 .

[0332] On the other hand, in the cover opening step ( S20 ), the control part 400 may open the cover control frame 530 .

[0333] Specifically, upon receiving a signal indicating that the dust box 220 is engaged, the control unit 400 operates the lid control motor 520 to rotate the lid control gear 510. This causes the gear unit 512 to mesh with the driven gear 532, thereby rotating the frame body 531. The driven gear 532 may mesh with the gear unit 512 after a predetermined time has passed since the lid control motor 520 was operated.

[0334] As a result, the cover control frame 530 rotates to open the dust passage hole 121a. That is, in the cover opening step (S20), the control unit 400 rotates the cover control frame 530 to open at least a portion of the dust passage hole 121a.

[0335] At this time, the control unit 400 receives a signal indicating that the second sensing protrusion 514bb is sensed from the cover control sensor 540. Thus, the control unit 400 can determine that the cover control frame 530 is in a fully opened state.

[0336] Thereafter, the control portion 400 causes the cover control motor 520 to continue operating for a preset time period.

[0337] Specifically, the control portion 400 may operate the cover control motor 520 until a signal is received from the cover control sensor 540 that the third sensing protrusion 514 bc is sensed.

[0338] Furthermore, when the lid control sensor 540 receives a signal that the third sensing protrusion 514bc is sensed, the control unit 400 can stop the operation of the lid control motor 520. In this case, the driven gear 532 and the cam portion 513 are in contact with each other and stopped. With this structure, the lid control frame 530 can maintain the dust passage hole 121a open.

[0339] At this time, the control unit 400 proceeds to the dust collecting step (S30).

[0340] In the dust collecting step ( S30 ), the discharge cover 222 is opened. When the cover control frame 530 rotates to open the dust passing hole 121 a , the dust collecting motor 191 is operated to collect dust inside the dust box 220 .

[0341] For example, when receiving a signal from the cover control sensor 540 indicating that the third sensing protrusion 514bc is sensed, the control unit 400 may operate the dust collecting motor 191 .

[0342] As another example, when a time period of 4 seconds to 6 seconds has passed since the dust box was connected or the user inputted an operation, the control unit 400 starts the operation of the dust collection motor 191 .

[0343] In the dust collection step (S30), the control unit 400 rotates the dust collection motor 191 at a preset dust collection speed Ws for a preset dust collection time ts. As an example, in the dust collection step (S30), the control unit 400 may rotate the dust collection motor 191 at the dust collection speed Ws for a period of 5 seconds to 9 seconds, but the present invention is not limited thereto. The dust collection time may be set to a variable value based on the output of the dust collection motor 191 and the amount of dust stored in the dust box 220.

[0344] On the other hand, in the dust collection step (S30), the control unit can receive a signal from the lid control sensor 540 indicating that the third sensing protrusion 514bc has been sensed for a predetermined period of time after the dust collection step (S30) is started. This is because the rotation of the lid control gear 510 is immediately stopped after the lid control sensor 540 senses the third sensing protrusion 514bc, thereby maintaining the position of the third sensing protrusion 514bc.

[0345] According to the dust collecting step (S30), the dust inside the dust box 220 is 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 inside the dust box 220 without additional operation, thereby improving user convenience.

[0346] On the other hand, in the present invention, according to an embodiment, during the dust collection step (S30), the dust box 220 can be simultaneously fixed. Specifically, during the dust collection step (S30), the dust collection motor 191 is operated, and the suction force of the dust collection motor 191 can cause the fixing unit 130 to operate. In other words, during the dust 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 box 220.

[0347] With such a structure, even if vibration occurs in the cleaner base station 100 due to the operation of the dust collecting motor 191, the dust box 220 can be stably fixed.

[0348] Therefore, according to the present invention, the time required to secure or release the cleaner 200 is reduced, thereby reducing the overall operating time.

[0349] On the other hand, the control method of the vacuum cleaner base station according to one embodiment of the present invention may further include a cover closing step ( S40 ) of rotating the cover control frame 530 to block the dust passage hole 121 a .

[0350] At this time, in the cover closing step ( S40 ), the cover control motor 520 may start to operate while the dust collecting motor 191 is operating.

[0351] In the cover opening step ( S20 ) and the dust collecting step ( S30 ), the cam portion 513 and the driven gear 532 are supported in contact with each other, so it is necessary to release the contact between the cam portion 513 and the driven gear 532 when the operation of the dust collecting motor 191 ends.

[0352] Therefore, the lid control motor 520 may be started before the dust collection motor 191 is stopped. For example, in the lid closing step (S40), the control unit 400 may start the lid control motor 520 when a time period of 3 seconds to 5 seconds has passed since the dust collection motor 191 was started. Therefore, the dust collection motor 191 and the lid control motor 520 may be operated together for a period of 2 seconds to 4 seconds.

[0353] Thus, the timing of ending the operation of the dust collecting motor 191 and closing the discharge cover 222 can be controlled to be the same.

[0354] On the other hand, in the lid closing step ( S40 ) of the embodiment of the present invention, the control unit 400 may operate the lid control motor 520 in a fixed direction.

[0355] That is, in the cover closing step ( S40 ), the control unit 400 maintains the rotation direction of the shaft of the cover control motor 520 to be the same as that in the cover opening step ( S20 ) and the dust collecting step ( S30 ).

[0356] Specifically, the control unit 400 causes the dust collection motor 191 to continue to operate in the same direction, thereby releasing the contact between the cam portion 513 and the driven gear 532. At this time, the return rod 533 is pulled downward by the restoring force of the return spring 550, and the frame body 531 rotates from the inside of the vacuum cleaner base station 100 toward the dust passage hole 121a with the hinge portion as the axis.

[0357] As a result, as the frame body 531 and the discharge cover 222 rotate together, the discharge cover 222 is coupled to the dust box body 221. Therefore, the communication between the internal space of the dust box 220 and the flow path portion 180 can be cut off.

[0358] Thus, during the lid opening step (S20), dust collection step (S30), and lid closing step (S40), the lid control gear 510 can rotate once due to the operation of the lid control motor 520. Furthermore, during each rotation of the lid control gear 510, the lid control frame 530 can change its rotation direction at least once. For example, the lid control frame 530 can rotate toward the inside of the vacuum cleaner base station 100 during the lid opening step (S20) and toward the outside of the vacuum cleaner base station 100 during the lid closing step (S40).

[0359] That is, in the present invention, while the cover control motor 520 rotates in one direction, the cover control frame 530 may switch the rotation direction at least once.

[0360] On the other hand, in the lid closing step (S40), the control unit may receive a signal again after finishing receiving a signal from the lid control sensor 540. Specifically, the control unit may finish receiving a signal from the lid control sensor 540 when sensing the third sensing protrusion 514bc and, after a predetermined time, may receive a signal when sensing the first sensing protrusion 514ba.

[0361] Thus, the control unit 400 can determine that the process of emptying the dust box 220 once is completed and prepare for the process of emptying the dust box 220 again.

[0362] Therefore, when receiving a signal indicating that the first sensing protrusion 514 ba is sensed, the control part 400 ends the operation of the cap control motor 520 .

[0363] Therefore, according to the present invention, the control unit 400 can precisely control the movement of the cap control frame 530 and thus control the discharge cap 222 without using an encoder or the like and without changing the operating direction of the cap control motor 520 .

[0364] In addition, according to the present invention, the cover control frame 530 is moved to open the discharge cover 222 of the dust box and the dust collecting motor 191 is operated. When the operation of the dust collecting motor 191 is ended, the discharge cover 222 is closed to reduce the time required for collecting dust in the dust box 220.

[0365] The present invention has been described in detail above through specific embodiments, but this is only for the purpose of describing the present invention in detail. The present invention is not limited thereto, and those skilled in the art may modify or improve the present invention within the technical concept of the present invention.

[0366] Simple modifications and changes of the present invention all fall within the scope of the present invention, and the specific protection scope of the present invention can be clearly understood through the appended claims.
