Description

Technical Field

[0001] This invention relates to a vacuum cleaner base station and a vacuum cleaner system, and more specifically, to a vacuum cleaner base station and a vacuum cleaner system capable of sucking dust stored in a vacuum cleaner into the interior of the vacuum cleaner base station and removing foreign objects remaining around the vacuum cleaner door. Background Technology

[0002] Generally, a vacuum cleaner is a household appliance that uses electricity to suck up small pieces of trash or dust and fills them into a dustbin inside the product; it is usually called a vacuum cleaner.

[0003] Vacuum cleaners can be categorized into manual and automatic types. Manual vacuum cleaners are those that the user directly moves and cleans, while automatic vacuum cleaners move and clean automatically. Manual vacuum cleaners can be further classified by their form factor, including canister-type, upright, handheld, and stick-type vacuum cleaners.

[0004] Previously, most household vacuum cleaners were canister vacuums, but in recent years, handheld and stick vacuums, which integrate the dustbin and the main body of the vacuum cleaner into one unit, have become increasingly popular, improving ease of use.

[0005] In a canister vacuum cleaner, a rubber hose or pipe is used to connect the main body and the suction port. A brush can be attached to the suction port as needed.

[0006] Handheld vacuum cleaners maximize portability. While lightweight, their short length requires squatting to clean, limiting the cleaning area. Therefore, they are best suited for cleaning specific areas such as desks, sofas, or car interiors.

[0007] Stick vacuum cleaners can be used standing up, allowing for cleaning without bending over. This makes them advantageous for moving and cleaning in spacious areas. Compared to handheld vacuum cleaners, which are designed for narrow spaces, stick vacuum cleaners can clean much wider areas and reach high places that are inaccessible by hand. In recent years, stick vacuum cleaners have been offered in modular form, allowing for proactive changes in vacuum cleaner type and usage for a variety of objects.

[0008] In addition, a type of robotic vacuum cleaner that can clean itself without user intervention is currently in use. This robotic vacuum cleaner automatically cleans the area by sucking up dust and other debris from the floor as it moves around.

[0009] However, in existing handheld vacuum cleaners, stick vacuum cleaners, and robotic vacuum cleaners, the dust collection bins used to store the collected dust have a small capacity, which makes it inconvenient for users to empty the dust collection bins every time.

[0010] In addition, there is a problem that when the dust collection bin is emptied, the dust may scatter and adversely affect the user's health.

[0011] In addition, there is a problem that the vacuum cleaner's suction power decreases when residual dust in the dustbin is not removed.

[0012] In addition, there is a problem that when the residual dust in the dust collection bin is not removed, the residue will produce a foul odor.

[0013] As an existing patent document, Korean Patent Publication No. 10-2020-0074001 discloses a cleaning device including a vacuum cleaner and a docking base station.

[0014] The aforementioned existing patent documents include a vacuum cleaner with a dust collection cylinder for collecting foreign objects and a docking station connected to the dust collection cylinder to remove foreign objects collected in the dust collection cylinder. The dust collection cylinder is configured to dock with the docking station, and the docking station is provided with a suction device for sucking in foreign objects and internal air from the dust collection cylinder docked with the docking station.

[0015] In addition, the aforementioned existing patent documents are configured to include a collection unit for capturing foreign objects inside the docking base station.

[0016] However, the aforementioned existing patent documents have the following problem: they cannot remove foreign objects remaining around the mounting part combined with the dust collection cylinder and in the suction flow path of foreign objects after the suction device (suction fan) has finished suctioning.

[0017] Therefore, after the foreign object inhalation process is over, users face the inconvenience of needing to use wet wipes or similar items to remove any remaining dust.

[0018] In addition, the accumulation of such foreign objects inside the docking base station poses a risk of contamination of the base station's interior. Summary of the Invention

[0019] The problem that the invention aims to solve

[0020] The present invention is proposed to improve the problems existing in the existing vacuum cleaner base station, vacuum cleaner system and control method as described above, and its purpose is to provide a vacuum cleaner base station that can remove dirt remaining in the dust collection bin, joint or flow path even after collecting dust inside the dust collection bin.

[0021] In addition, the purpose of this invention is to provide a vacuum cleaner base station that can remove dust from the dust collection bin even without additional user operation, thereby improving user convenience.

[0022] In addition, the present invention aims to provide a vacuum cleaner base station that can prevent hair or other objects from getting tangled in the dust collection bin, joint, or flow path.

[0023] In addition, the purpose of this invention is to provide a vacuum cleaner base station that can prevent suction loss caused by foreign objects remaining inside the flow path.

[0064] Figure 1 This is a perspective view illustrating a vacuum cleaner system comprising a vacuum cleaner base station, a first vacuum cleaner, and a second vacuum cleaner, according to an embodiment of the present invention. Figure 2 This is a schematic diagram illustrating the configuration of a vacuum cleaner system according to an embodiment of the present invention.

[0065] Reference Figure 1 and Figure 2 In one embodiment of the present invention, a vacuum cleaner system 10 may include a vacuum cleaner base station 100 and vacuum cleaners 200 and 300. In this case, vacuum cleaners 200 and 300 may include a first vacuum cleaner 200 and a second vacuum cleaner 300. On the other hand, in this embodiment, some components may be omitted, and additional components are not excluded.

[0066] The vacuum cleaner system 10 may include a vacuum cleaner base station 100. A first vacuum cleaner 200 and a second vacuum cleaner 300 may be integrated into the vacuum cleaner base station 100. The first vacuum cleaner 200 may be integrated into the side of the vacuum cleaner base station 100. Specifically, the main body of the first vacuum cleaner 200 may be integrated into the side of the vacuum cleaner base station 100. The second vacuum cleaner 300 may be integrated into the lower part of the vacuum cleaner base station 100. The vacuum cleaner base station 100 can remove dust from the dustbin 220 of the first vacuum cleaner 200. The vacuum cleaner base station 100 can remove dust from the dustbin (not shown) of the second vacuum cleaner 300.

[0067] on the other hand, Figures 3 to 5 This is a diagram illustrating the first vacuum cleaner in a vacuum cleaner system according to an embodiment of the present invention.

[0068] First, refer to Figures 1 to 5 This describes the structure of the first vacuum cleaner 200.

[0069] The first vacuum cleaner 200 can refer to a vacuum cleaner that is manually operated by the user. For example, the first vacuum cleaner 200 can refer to a handheld vacuum cleaner or a stick vacuum cleaner.

[0070] The first vacuum cleaner 200 can be placed on the vacuum cleaner base station 100. The first vacuum cleaner 200 can be supported by the vacuum cleaner base station 100. The first vacuum cleaner 200 can be integrated with the vacuum cleaner base station 100.

[0071] On the other hand, in one embodiment of the present invention, the orientation can be defined with reference to the bottom surface (lower side) of the dust collection bin 220 and the battery housing 230 when they are placed on the ground.

[0072] At this time, "front" can refer to the direction in which the suction unit 212 is arranged with reference to the suction motor 214, and "rear" can refer to the direction in which the handle 216 is arranged with reference to the suction motor 214. Furthermore, based on the view of the suction unit 212 from the suction motor 214, the direction on the right can be called the right side, and the direction on the left can be called the left side. Additionally, in one embodiment of the present invention, based on the bottom surface (lower side) of the dust collection bin 220 and the battery casing 230 being placed on the ground, the upper and lower sides can be defined along a direction perpendicular to the ground.

[0073] The first vacuum 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 exhaust cover 215, a handle 216, and an operation unit 218.

[0074] The main housing 211 can form the appearance of the first vacuum cleaner 200. The main housing 211 can provide internal space to accommodate the suction motor 214 and the filter (not shown). The main housing 211 can be configured in a cylindrical shape.

[0075] The suction section 212 can protrude outward from the main housing 211. As an example, the suction section 212 can be formed into a cylindrical shape with an internal opening. The suction section 212 can be combined with the extension tube 250. The suction section 212 can provide a flow path (hereinafter referred to as "suction flow path") through which air containing dust can flow.

[0076] On the other hand, in this embodiment, a virtual line can be formed that penetrates the interior of the cylindrical suction section 212. That is, a virtual suction flow path through line a2 that penetrates the suction flow path along the length direction can be formed.

[0077] The dust separation section 213 can communicate with the suction section 212. The dust separation section 213 can separate the dust that is sucked into the interior via the suction section 212. The space inside the dust separation section 213 can communicate with the space inside the dust collection bin 220.

[0078] For example, the dust separation section 213 may include at least two swirling sections capable of separating dust through swirling flow. Furthermore, the space inside the dust separation section 213 may communicate with the suction flow path. Therefore, air and dust drawn in via the suction section 212 can flow spirally along the inner circumferential surface of the dust separation section 213. Thus, swirling flow can be generated within the internal space of the dust separation section 213.

[0079] The dust separation section 213 is connected to the suction section 212, and the dust separation section 213 is constructed using the principle of a dust collector that utilizes centrifugal force to separate the dust that is sucked into the interior of the main body 210 via the suction section 212.

[0080] As an example, the dust separation section 213 may include at least one cyclone separator capable of separating dust using swirling currents. The cyclone separator may be in communication with the suction section 212. Air and dust drawn in via the suction section 212 may flow spirally along the inner circumferential surface of the cyclone separator.

[0081] The dust separation section 213 may further include a secondary cyclone for further separating dust from the air discharged from the cyclone. In this case, the secondary cyclone may be located inside the cyclone to minimize the size of the dust separation section. The secondary cyclone may include a plurality of cyclone bodies arranged side by side. The air discharged from the cyclone may be diverted through the plurality of cyclone bodies.

[0082] At this time, the swirling axis of the secondary cyclone separator can also extend in the vertical direction. The swirling axis of the secondary cyclone separator and the swirling axis of the secondary cyclone separator can be coaxial in the vertical direction, and can be collectively referred to as the swirling axis of the dust separation section 213. On the other hand, in this embodiment, a virtual swirling line a4 can be formed relative to the aforementioned swirling axis.

[0083] The dust separation unit 213 may also include a cyclone filter configured to surround the secondary cyclone. As an example, the cyclone filter is formed in a cylindrical shape and guides the air separated from dust in the cyclone toward the secondary cyclone. The cyclone filter can filter dust as the air passes through.

[0084] Therefore, a cyclone filter may include a mesh portion having a plurality of holes. The mesh portion may be made of metal, but is not limited thereto.

[0085] The suction motor 214 can generate suction to draw in air. The suction motor 214 can be housed within the main body housing 211. The suction motor 214 can generate suction by rotation. As an example, the suction motor 214 can be configured in a shape similar to a cylinder.

[0086] On the other hand, in this embodiment, a virtual suction motor axis a1 may be formed that extends the rotation axis of the suction motor 214.

[0087] An air exhaust cover 215 may be disposed on one axial side of the main housing 211. An air filter for filtering air may be housed in the air exhaust cover 215. For example, a high-efficiency particulate air (HEPA) filter may be housed in the air exhaust cover 215.

[0088] An air outlet 215a can be formed in the air outlet cover 215 to discharge air drawn in by the suction of the suction motor 214.

[0089] A flow guide may be provided on the air exhaust cover 215. The flow guide can guide the flow of air discharged through the air exhaust port 215a.

[0090] The handle 216 can be gripped by a user. The handle 216 can be configured behind the suction motor 214. As an example, the handle 216 can be formed in a cylindrical shape. Alternatively, the handle 216 can be formed in a curved cylindrical shape. The handle 216 can be configured to form a predetermined angle with the main housing 211, the suction motor 214, or the dust separation section 213.

[0091] The handle 216 may include: a grip portion 216a, which is formed in a cylindrical shape for a user to grip; a first extension portion 216b, which is connected to one end of the grip portion 216a in the longitudinal direction (axial direction) and extends toward the suction motor 214; and a second extension portion 216c, which is connected to the other end of the grip portion 216a in the longitudinal direction (axial direction) and extends toward the dust collection bin 220.

[0092] On the other hand, in this embodiment, a virtual gripping part through line a3 can be formed that extends along the length direction (axial direction of the column) of the gripping part 216a and penetrates the gripping part 216a.

[0093] As an example, the through line a3 of the grip portion can be a virtual line formed inside the cylindrical handle 216, and can be a virtual line formed parallel to at least a portion of the outer surface (outer peripheral surface) of the grip portion 216a.

[0094] The top surface of the handle 216 can form part of the appearance of the top surface of the vacuum cleaner 200. This prevents a part of the vacuum cleaner 200 from coming into contact with the user's arm when the user is holding the handle 216.

[0095] The first extension 216b can extend from the grip 216a toward the main housing 211 or the suction motor 214. At least a portion of the first extension 216b can extend in a horizontal direction.

[0096] The second extension 216c can extend from the grip 216a toward the dust collection bin 220. At least a portion of the second extension 216c can extend in a horizontal direction.

[0097] The operation unit 218 can be configured on the handle 216. The operation unit 218 can be configured on an inclined surface formed in the upper region of the handle 216. The user can input operation or stop commands for the first vacuum cleaner 200 through the operation unit 218.

[0098] The first vacuum cleaner 200 may include a dust collection bin 220. The dust collection bin 220 may be in communication with a dust separation section 213. The dust collection bin 220 may store dust separated from the dust separation section 213.

[0099] The dust collection bin 220 may include a dust collection bin body 221, a discharge cover 222, a dust collection bin compression rod 223, and a compression component (not shown).

[0100] The dust collection bin body 221 can provide a space for storing dust separated from the dust separation section 213. As an example, the dust collection bin body 221 can be formed in a cylindrical shape.

[0101] On the other hand, in this embodiment, a virtual dust collection bin through line a5 can be formed, which penetrates the interior (internal space) of the dust collection bin body 221 and extends along the length direction of the dust collection bin body 221 (i.e., the axial direction of the cylindrical dust collection bin body 221).

[0102] A portion of the lower side (bottom) of the dust collection bin body 221 can be opened. Additionally, a lower side extension 221a can be formed on the lower side (bottom) of the dust collection bin body 221. The lower side extension 221a can be formed to cover a portion of the lower side of the dust collection bin body 221.

[0103] The dust collection bin 220 may include a discharge cover 222. The discharge cover 222 may be disposed on the lower side of the dust collection bin 220.

[0104] The discharge cover 222 can be configured to open and close one end of the dust collection bin body 221 along its length. Specifically, the discharge cover 222 can selectively open and close the lower part of the dust collection bin 220, which has a downward opening.

[0105] The discharge cover 222 may include a cover body 222a and a hinge portion 222b. The cover body 222a may be formed to cover part of the lower side of the dust collection bin body 221. The cover body 222a may rotate downward with respect to the hinge portion 222b. The hinge portion 222b may be configured adjacent to the battery housing 230. As an example, the hinge portion 222b may include a torsion spring 222d. Therefore, when the discharge cover 222 is separated from the dust collection bin body 221, the cover body 222a may be supported by the elastic force of the torsion spring 222d to a state in which it can rotate more than a predetermined angle from the dust collection bin body 221 about the hinge portion 222b.

[0106] The discharge cover 222 can be attached to the dust collection bin 220 via a hook-and-loop connection. Conversely, the discharge cover 222 can be detached from the dust collection bin 220 using a connecting rod 222c. The connecting rod 222c can be positioned at the front of the dust collection bin. Specifically, the connecting rod 222c can be positioned on the outer front side of the dust collection bin 220. When an external force is applied, the connecting rod 222c can elastically deform the hook extending from the cover body 222a, thereby releasing the hook-and-loop connection between the cover body 222a and the dust collection bin body 221.

[0107] With the discharge cover 222 closed, the lower side of the dust collection bin 220 can be covered (sealed) by the discharge cover 222 and the lower side extension 221a.

[0108] Dust collection bin 220 may include dust collection bin compression rod 223 (see reference) Figure 7 The dust collection bin compression rod 223 can be disposed outside the dust collection bin 220 or the dust separation section 213. The dust collection bin compression rod 223 is disposed outside the dust collection bin 220 or the dust separation section 213 in a manner that allows it to move up and down. The dust collection bin compression rod 223 can be connected to a compression member (not shown). When the dust collection bin compression rod 223 moves downward due to an external force, the compression member (not shown) can also move downward together. This improves user convenience. The compression member (not shown) and the dust collection bin compression rod 223 can be reset to their original positions under the action of an elastic member (not shown). Specifically, when the external force applied to the dust collection bin compression rod 223 is removed, the elastic member can cause the dust collection bin compression rod 223 and the compression member (not shown) to move upward.

[0109] A compression member (not shown) can be disposed inside the dust collection bin body 221. The compression member can move within the internal space of the dust collection bin body 221. Specifically, the compression member can move up and down within the dust collection bin body 221. This allows the compression member to compress the dust within the dust collection bin body 221 downwards. Furthermore, when the discharge cover 222 separates from the dust collection bin body 221, opening the lower part of the dust collection bin 220, the compression member can move from the upper part of the dust collection bin 220 downwards and remove any remaining dust or other foreign matter within the dust collection bin 220. This prevents residual dust from remaining in the dust collection bin 220, thereby improving the suction power of the vacuum cleaner. Furthermore, by preventing residual dust from remaining in the dust collection bin 220, unpleasant odors caused by residue can be eliminated.

[0110] The first vacuum cleaner 200 may include a battery housing 230. A battery 240 may be housed in the battery housing 230. The battery housing 230 may be disposed on the underside of the handle 216. As an example, the battery housing 230 may be a hexahedral shape with an open bottom. The back side of the battery housing 230 may be connected to the handle 216.

[0111] The battery housing 230 may include a downwardly opening receiving portion. The battery 240 can be installed or removed through the receiving portion of the battery housing 240.

[0112] The first vacuum cleaner 200 may include a battery 240.

[0113] For example, the battery 240 can be detachably attached to the first vacuum cleaner 200. The battery 240 can also be detachably attached to the battery housing 230. As an example, the battery 240 can be inserted into the interior of the battery housing 230 from below. With the configuration described above, the portability of the first vacuum cleaner 200 can be improved.

[0114] In contrast, the battery 240 can be integrally formed inside the battery housing 230. In this case, the lower side of the battery 240 will not be exposed to the outside.

[0115] The battery 240 can power the suction motor 214 of the first vacuum cleaner 200. The battery 240 can be positioned at the lower part of the handle 216. The battery 240 can also be positioned behind the dustbin 220. That is, the suction motor 214 and the battery 240 can be arranged vertically without overlapping, and their heights can also be different. With the handle 216 as a reference, the heavier suction motor 214 is positioned in front of the handle 216, and the heavier battery 240 is positioned below the handle 216, thus distributing the weight of the vacuum cleaner 200 evenly. This prevents wrist strain when the user holds the handle 216 while cleaning.

[0116] According to the embodiment, when the battery 240 is attached to the battery housing 230, the lower side of the battery 240 can be exposed to the outside. Since the battery 240 can be placed on the ground when the first vacuum cleaner 200 is placed on the ground, the battery 240 can be directly detached from the battery housing 230. In addition, since the lower side of the battery 240 is exposed to the outside and in direct contact with the air outside the battery 240, the cooling performance of the battery 240 can be improved.

[0117] On the other hand, when the battery 240 is integrally fixed to the battery housing 230, the structure for attaching and detaching the battery 240 and the battery housing 230 can be reduced, thus reducing the overall size of the vacuum cleaner 200 and achieving lightweighting.

[0118] The first vacuum cleaner 200 may include an extension tube 250. The extension tube 250 may communicate with the cleaning module 260. The extension tube 250 may communicate with the main body 210. The extension tube 250 may communicate with the suction section 212 of the main body 210. The extension tube 250 may be formed into an elongated cylindrical shape.

[0119] The main body 210 can be connected to the extension tube 250. The main body 210 can be connected to the cleaning module 260 via the extension tube 250. The main body 210 can generate suction using the suction motor 214 and can provide suction to the cleaning module 260 via the extension tube 250. External dust can flow into the main body 210 via the cleaning module 260 and the extension tube 250.

[0120] The first vacuum cleaner 200 may include a cleaning module 260. The cleaning module 260 may be connected to an extension tube 250. Therefore, external air can flow into the body 210 of the first vacuum cleaner 200 through the cleaning module 260 and the extension tube 250 under the suction generated by the body 210 of the first vacuum cleaner 200.

[0121] Dust in the dustbin 220 of the first vacuum cleaner 200 can be captured and collected in the dust collection section 170 of the vacuum cleaner base station 100 by gravity and the suction of the dust collection motor 191. Therefore, dust in the dustbin can be removed without additional user intervention, thus improving user convenience. Furthermore, it eliminates the inconvenience of having to empty the dustbin each time. Additionally, it prevents dust from scattering when the dustbin is emptied.

[0122] The first vacuum cleaner 200 can be attached to the side of the housing 110. Specifically, the main body 210 of the first vacuum cleaner 200 can be placed in the connecting part 120. More specifically, the dust collection bin 220 and the battery housing 230 of the first vacuum cleaner 200 can be attached to the connecting surface 121, the outer peripheral surface of the dust collection bin main body 221 can be attached to the dust collection bin guide surface 122, and the suction part 212 can be attached to the suction part guide surface 126 of the connecting part 120. In this case, the central axis of the dust collection bin 220 is arranged in a direction parallel to the ground, and the extension tube 250 can be arranged in a direction perpendicular to the ground (see reference). Figure 2 ).

[0123] The vacuum cleaner system 10 may include a second vacuum cleaner 300. The second vacuum cleaner 300 may refer to a robotic vacuum cleaner. The second vacuum cleaner 300 automatically cleans the area to be cleaned by sucking up dust and other foreign objects from the ground while autonomously moving within the area. The second vacuum cleaner 300, i.e., the robotic vacuum cleaner, may include a distance sensor for detecting the distance to obstacles such as furniture, office supplies, or walls placed within the cleaning area, as well as left and right wheels for the movement of the robotic vacuum cleaner. The second vacuum cleaner 300 may be integrated with the vacuum cleaner base station 100. Dust within the second vacuum cleaner 300 can be captured and collected in the dust collection section 170 via the second flow path section 182.

[0124] Reference Figure 1 and Figure 2 This describes the vacuum cleaner base station 100 of the present invention.

[0125] A first vacuum cleaner 200 and a second vacuum cleaner 300 can be configured in the vacuum cleaner base station 100. The first vacuum cleaner 200 can be attached to the side of the vacuum cleaner base station 100. Specifically, the main body of the first vacuum cleaner 200 can be attached to the side of the vacuum cleaner base station 100. The second vacuum cleaner 300 can be attached to the lower part of the vacuum cleaner base station 100. The vacuum cleaner base station 100 can remove dust from the dust collection bin 220 of the first vacuum cleaner 200. The vacuum cleaner base station 100 can remove dust from the dust collection bin (not shown) of the second vacuum cleaner 300.

[0126] The vacuum cleaner base station 100 may include a housing 110. The housing 110 may form the appearance of the vacuum cleaner base station 100. Specifically, the housing 110 may be formed into a columnar shape including at least one or more outer wall surfaces. As an example, the housing 110 may be formed into a shape similar to a rectangular column.

[0127] The interior of the housing 110 can form a space that can accommodate a dust collection section 170 for storing dust and a dust suction module 190 for generating a flow force that causes dust to be collected into the dust collection section 170.

[0128] The housing 110 may include a bottom surface 111, an outer wall surface 112, and a top surface 113.

[0129] The bottom surface 111 can support the lower side of the dust suction module 190 in the direction of gravity. That is, the bottom surface 111 can support the lower side of the dust collection motor 191 of the dust suction module 190.

[0130] At this time, the bottom surface 111 can be positioned facing the ground. The bottom surface 111 can be positioned not only parallel to the ground, but also inclined at a specified angle to the ground. With such a structure, it has the advantage of being able to stably support the dust collection motor 171, and maintaining overall weight balance even when combined with the first vacuum cleaner 200.

[0131] On the other hand, according to the embodiment, the bottom surface 111 may also include a ground support portion 111a that increases the contact area with the ground to prevent the vacuum cleaner base station 100 from tipping over and to maintain balance. As an example, the ground support portion may be a plate shape extending from the bottom surface 111, or it may be formed by one or more frames protruding from the bottom surface 111 toward the ground.

[0132] The outer wall surface 112 can refer to a surface formed along the direction of gravity, or it can refer to a surface connected to the bottom surface 111. For example, the outer wall surface 112 can refer to a surface that is perpendicularly connected to the bottom surface 111. In a different embodiment, the outer wall surface 112 can also be configured at an angle to the bottom surface 111.

[0133] The outer wall surface 112 may be configured to include at least one surface. As an example, the outer wall surface 112 may include a first outer wall surface 112a, a second outer wall surface 112b, a third outer wall surface 112c, and a fourth outer wall surface 112d.

[0134] In this embodiment, the first outer wall surface 112a can be disposed on the front side of the vacuum cleaner base station 100. Here, the front side can refer to the surface of the first vacuum cleaner 200 exposed when the first vacuum cleaner 200 is combined with the vacuum cleaner base station 100. Therefore, the first outer wall surface 112a can form the appearance of the front side of the vacuum cleaner base station 100.

[0135] On the other hand, the direction is defined to understand this embodiment. In this embodiment, the direction can be defined when the first vacuum cleaner 200 is placed on the vacuum cleaner base station 100.

[0136] When the first vacuum cleaner 200 is placed on the vacuum cleaner base station 100, the direction in which the first vacuum cleaner 200 is exposed to the outside from the vacuum cleaner base station 100 can be referred to as the front.

[0137] On the other hand, when the first vacuum cleaner 200 is placed in the vacuum cleaner base station 100, the direction in which the suction motor 214 of the first vacuum cleaner 200 is located can be referred to as the front. Furthermore, in the vacuum cleaner base station 100, the opposite direction to the direction in which the suction motor 214 is located can be referred to as the rear.

[0138] From another perspective, taking the vacuum cleaner base station 100 as a reference, the direction at the intersection of the grip through line a3 and the suction motor axis a1 can be called the front. Alternatively, the direction at the intersection P2 of the grip through line a3 and the suction flow path through line a2 can be called the front. Alternatively, the direction at the intersection P1 of the suction motor axis a1 and the suction flow path through line a2 can be called the front. Furthermore, taking the vacuum cleaner base station 100 as a reference, the direction opposite to the aforementioned intersections can be called the rear.

[0139] Furthermore, the surface facing the front can be referred to as the back side of the vacuum cleaner base station 100, based on the internal space of the housing 110. Therefore, the back side can refer to the direction in which the second outer wall surface 112b is formed.

[0140] Furthermore, when viewing the front surface with reference to the internal space of the housing 110, the left side can be referred to as the left side, and the right side as the right side. Therefore, the left side can refer to the direction in which the third outer wall surface 112c is formed, and the right side can refer to the direction in which the fourth outer wall surface 112d is formed.

[0141] The first outer wall surface 112a can be formed as a planar shape, or as a curved surface as a whole, or as a part of which includes a curved surface.

[0142] The first outer wall surface 112a may have an appearance corresponding to the shape of the first vacuum cleaner 200. Specifically, a connecting portion 120 may be provided on the first outer wall surface 112a. With this structure, the first vacuum cleaner 200 can be attached to and supported by the vacuum cleaner base station 100. The specific structure of the connecting portion 120 will be described later.

[0143] On the other hand, a structure for placing various types of cleaning modules 260 used on the first vacuum cleaner 200 can also be added to the first outer wall surface 112a.

[0144] Furthermore, a structure that can be attached to the second vacuum cleaner 300 can be added to the first outer wall surface 112a. Therefore, a structure corresponding to the shape of the second vacuum cleaner 300 can be added to the first outer wall surface 112a.

[0145] Furthermore, a vacuum cleaner base plate (not shown) may be additionally attached to the first outer wall surface 112a for attachment to the lower side of the second vacuum cleaner 300. Alternatively, in a different embodiment, the vacuum cleaner base plate (not shown) may be configured to be connected to the bottom surface 111.

[0146] In this embodiment, the second outer wall surface 112b can be the surface opposite to the first outer wall surface 112a. That is, the second outer wall surface 112b can be disposed on the back side of the vacuum cleaner base station 100. Here, the back side can refer to the surface opposite to the surface where the first vacuum cleaner 200 or the second vacuum cleaner 300 is attached. Therefore, the second outer wall surface 112b can form the appearance of the back side of the vacuum cleaner base station 100.

[0147] As an example, the second outer wall surface 112b can be formed into a planar shape. With such a structure, the vacuum cleaner base station 100 can be closely attached to the indoor wall and can be stably supported.

[0148] As another example, a structure for placing various types of cleaning modules 260 used on the first vacuum cleaner 200 can also be added to the second outer wall surface 112b.

[0149] In this embodiment, the third outer wall surface 112c and the fourth outer wall surface 112d can refer to the surfaces connecting the first outer wall surface 112a and the second outer wall surface 112b. In this case, the third outer wall surface 112c can be disposed on the left side of the base station 100, and the fourth outer wall surface 112d can be disposed on the right side of the vacuum cleaner base station 100. Alternatively, the third outer wall surface 112c can also be disposed on the right side of the vacuum cleaner base station 100, and the fourth outer wall surface 112d can be disposed on the left side of the vacuum cleaner base station 100.

[0150] The third outer wall surface 112c or the fourth outer wall surface 112d can be formed as a planar shape, or as a curved surface as a whole, or as a part of which includes a curved surface.

[0151] On the other hand, a structure for placing various types of cleaning modules 260 used on the first vacuum cleaner 200 can be added to the third outer wall surface 112c or the fourth outer wall surface 112d.

[0152] The upper surface 113 can form the upper appearance of the vacuum cleaner base station. That is, the upper surface 113 can refer to the surface that is located at the uppermost side in the direction of gravity and exposed to the outside in the vacuum cleaner base station.

[0153] For reference, in this embodiment, the upper side and the lower side can refer to the upper side and the lower side along the direction of gravity (the direction perpendicular to the ground) when the vacuum cleaner base station 100 is set on the ground.

[0154] At this time, the upper surface 113 can not only be arranged parallel to the ground, but also can be arranged at an angle to the ground.

[0155] A display unit 410 may be provided on the upper surface 113. For example, the display unit 410 may display the status of the vacuum cleaner base station 100, the status of the first vacuum cleaner 200 and the status of the second vacuum cleaner 300. In addition, it may also display information such as the cleaning progress and a map of the cleaning area.

[0156] On the other hand, according to the embodiment, the upper surface 113 can be detachably disposed on the outer wall surface 112. In this case, if the upper surface 113 is detached, the internal space surrounded by the outer wall surface 112 can accommodate the battery detached from the vacuum cleaner 200, 300, and can be provided with a terminal (not shown) capable of charging the detached battery.

[0157] Figure 6 This is a diagram illustrating the joint of the vacuum cleaner base station according to an embodiment of the present invention. Figure 7 This is a perspective view illustrating the fixed unit in the vacuum cleaner base station according to an embodiment of the present invention. Figures 8 to 11 This diagram illustrates the relationship between the first vacuum cleaner and the door unit in a vacuum cleaner base station according to an embodiment of the present invention. Figure 12 This is a diagram illustrating the relationship between the first vacuum cleaner and the cover opening unit in a vacuum cleaner base station according to an embodiment of the present invention.

[0158] Reference Figure 2 and Figure 6 This section describes the connecting portion 120 of the vacuum cleaner base station 100 of the present invention.

[0159] The vacuum cleaner base station 100 may include a connecting portion 120 for connecting a first vacuum cleaner 200. Specifically, the connecting portion 120 may be disposed on a first outer wall surface 112a, and the main body 210, dust collection bin 220, and battery housing 230 of the first vacuum cleaner 200 may be connected to the connecting portion 120.

[0160] The joint 120 may include a mating surface 121. The mating surface 121 may be disposed on the side of the housing 110. As an example, the mating surface 121 may refer to a surface that is recessed into the inner side of the vacuum cleaner base station 100 from the first outer wall surface 112a in the shape of a groove. That is, the mating surface 121 may refer to a surface that is formed to form a step with the first outer wall surface 112a.

[0161] The first vacuum cleaner 200 can be attached to the mating surface 121. As an example, the mating surface 121 can contact the lower side of the dust collection bin 220 and the battery housing 230 of the first vacuum cleaner 200. Here, the lower side can refer to the surface facing the ground when the user uses the first vacuum cleaner 200 or places the first vacuum cleaner 200 on the ground.

[0162] As an example, the angle formed between the mating surface 121 and the ground can be a right angle. Thus, when the first vacuum cleaner 200 is mated to the mating surface 121, the space of the vacuum cleaner base station 100 can be minimized.

[0163] As another example, the mating surface 121 can be configured to be inclined at a predetermined angle to the ground. Thus, when the first vacuum cleaner 200 is mated to the mating surface 121, it can stably support the vacuum cleaner base station 100.

[0164] A dust passage hole 121a can be formed on the mating surface 121 to allow air from outside the housing 110 to flow into the interior. The dust passage hole 121a can be shaped to correspond to the shape of the dust collection bin 220, allowing dust from the dust collection bin 220 to flow into the dust collection section 170. The dust passage hole 121a can be formed to correspond to the shape of the discharge cover 222 of the dust collection bin 220. The dust passage hole 121a can be formed to communicate with the first vacuum cleaner flow path section 181 described later.

[0165] The mating portion 120 may include a dust collection bin guide surface 122. The dust collection bin guide surface 122 may be disposed on the first outer wall surface 112a. The dust collection bin guide surface 122 may be connected to the first outer wall surface 112a. In addition, the dust collection bin guide surface 122 may be connected to the mating surface 121.

[0166] The dust collection bin guide surface 122 can be formed in a shape corresponding to the outer surface of the dust collection bin 220. The front outer surface of the dust collection bin 220 can be attached to the dust collection bin guide surface 122. Thus, the first vacuum cleaner 200 can be conveniently attached to the attachment surface 121.

[0167] On the other hand, a raised moving hole 122a can be formed on the dust collection bin guide surface 122, and the pushing protrusion 151 described later can move linearly along the raised moving hole 122a. Additionally, a gearbox 155, which accommodates the gears of the cover opening unit 150 described later, can be provided on the lower side of the dust collection bin guide surface 122 in the direction of gravity. At this time, a guide space 122b can be formed between the lower side of the dust collection bin guide surface 122 and the upper side of the gearbox 155, allowing the pushing protrusion 151 to move. Furthermore, the guide space 122b can communicate with the first flow path 181a of the first vacuum cleaner flow path section 181 through a bypass hole 122c. That is, the raised moving hole 122a, the guide space 122b, the bypass hole 122c, and the first flow path 181a can form a bypass flow path (see reference). Figure 8 With this structure, when the dust collection motor 191 is running with the dust collection bin 220 and the connecting part 120 engaged, it has the advantage of being able to suck up dust remaining in the dust collection bin 220 and the dust collection bin guide surface 122 through the bypass flow path.

[0168] The connecting portion 120 may include guide protrusions 123. Guide protrusions 123 may be disposed on the connecting surface 121. Guide protrusions 123 may protrude upwards from the connecting surface 121. Two guide protrusions 123 may be arranged with a spacing between them. The distance between the two spaced-apart guide protrusions 123 may correspond to the width of the battery housing 230 of the first vacuum cleaner 200. This allows the first vacuum cleaner 200 to be conveniently connected to the connecting surface 121.

[0169] The joint 120 may include a joint sidewall 124. The sidewall 124 may refer to a wall surface disposed on both sides of the joint surface 121 and may be perpendicularly connected to the joint surface 121. The joint sidewall 124 may be connected to the first outer wall surface 112a. Furthermore, the joint sidewall 124 may form a surface that connects to the dust collection bin guide surface 122. Thus, the first vacuum cleaner 200 can be stably accommodated.

[0170] The coupling portion 120 may include a coupling sensor 125. The coupling sensor 125 can detect whether the first vacuum cleaner 200 is coupled to the coupling portion 120.

[0171] The engagement sensor 125 may also include a contact sensor. As an example, the engagement sensor 125 may include a micro switch. In this case, the engagement sensor 125 may be configured on the guide protrusion 123. Therefore, when the battery housing 230 or battery 240 of the first vacuum cleaner 200 is engaged between a pair of guide protrusions 123, it will contact the engagement sensor 125, enabling the engagement sensor 125 to detect that the first vacuum cleaner 200 has been engaged.

[0172] On the other hand, the sensor 125 may also include a non-contact sensor. For example, the sensor 125 may include an infrared sensor (IR sensor). In this case, the sensor 125 may be disposed on the sidewall 124 of the joint. Therefore, when the dustbin 220 or the main body 210 of the first vacuum cleaner 200 passes the sidewall 124 of the joint and reaches the joint surface 121, the sensor 125 can detect the presence of the dustbin 220 or the main body 210.

[0173] The sensor 125 can be positioned opposite the dustbin 220 or battery housing 230 of the first vacuum cleaner 200.

[0174] The sensor 125 can be used to determine whether power is applied to the battery 240 of the first vacuum cleaner 200 and whether the first vacuum cleaner 200 is connected.

[0175] The connecting portion 120 may include a suction portion guide surface 126. The suction portion guide surface 126 may be disposed on the first outer wall surface 112a. The suction portion guide surface 126 may be connected to the dust collection bin guide surface 122. The suction portion 212 may be coupled to the suction portion guide surface 126. The shape of the suction portion guide surface 126 may be formed to correspond to the shape of the suction portion 212.

[0176] The joint 120 may also include a fixing member access hole 127. The fixing member access hole 127 may be formed as an elongated hole along the side wall 124 of the joint to allow the fixing member 131 to enter and exit.

[0177] With this structure, when the user attaches the first vacuum cleaner 200 to the attachment portion 120 of the vacuum cleaner base station 100, the main body 210 of the first vacuum cleaner 200 is stably positioned in the attachment portion 120 under the action of the dust collection bin guide surface 122, the guide protrusion 123, and the suction part guide surface 126. This allows the dust collection bin 220 and the battery housing 230 of the first vacuum cleaner 200 to be conveniently attached to the attachment surface 121.

[0178] On the other hand, the vacuum cleaner base station 100 may also include a charging unit 128. The charging unit 128 may be disposed on the coupling portion 120. The charging unit 128 may be electrically connected to the first vacuum cleaner 200 coupled to the coupling portion 120. The charging unit 128 may supply power to the battery of the first vacuum cleaner 200 coupled to the coupling portion 120. In this case, the charging unit 128 may be a means of detecting the coupling of the first vacuum cleaner 200 and the vacuum cleaner base station 100 through its electrical connection with the first vacuum cleaner 200. Furthermore, the charging unit 128 may be a means of sending a predetermined electrical signal to the first vacuum cleaner 200, causing the control unit of the first vacuum cleaner 200 to detect the coupling of the first vacuum cleaner 200 and the vacuum cleaner base station 100.

[0179] Alternatively, the charging unit 128 may also include a lower charging unit (not shown) disposed in the lower region of the housing 110. The lower charging unit can be electrically connected to the second vacuum cleaner 300 coupled to the lower region of the housing 110. The second charger can supply power to the battery of the second vacuum cleaner 300 coupled to the lower region of the housing 110.

[0180] Reference Figure 2 and Figure 7 This describes the fixing unit 130 of the present invention.

[0181] 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 of the joint portion. Alternatively, the fixing unit 130 may be disposed on the back side of the joint surface 121. The fixing unit 130 may fix the first vacuum cleaner 200 to the joint surface 121. Specifically, the fixing unit 130 may fix the dust collection bin 220 and the battery housing 230 of the first vacuum cleaner 200 to the joint surface 121.

[0182] The fixing unit 130 may include: a fixing member 131 for fixing the dust collection bin 220 and battery housing 230 of the first vacuum cleaner 200; and a fixing motor 133 for driving the fixing member 131. In addition, the fixing unit 130 may also include a fixing link 135 for transmitting the power of the fixing motor 133 to the fixing member 131.

[0183] The fixing member 131 can be disposed on the side wall 124 of the joint and can be configured to reciprocate on the side wall 124 of the joint to fix the dust collection bin 220. Specifically, the fixing member 131 can be accommodated inside the fixing member inlet hole 127.

[0184] The fixing members 131 can be respectively disposed on both sides of the joint 120. As an example, the two fixing members 131 can be arranged symmetrically in pairs with the joint surface 121 as the center.

[0185] The fixed part motor 133 can provide the power to move the fixed member 131.

[0186] The connecting rod 135 of the fixed part can convert the rotational force of the fixed part motor 133 into the reciprocating movement of the fixed member 131.

[0187] The fixing seal 136 can be configured on the dust collection bin guide surface 122 to air-concentrate the dust collection bin 220 when the first vacuum cleaner 200 is engaged. With this structure, when the dust collection bin 220 of the vacuum cleaner 200 is engaged, the fixing seal 136 can be pressed down by the weight of the vacuum cleaner 200, thereby sealing the dust collection bin 220 and the dust collection bin guide surface 122.

[0188] The fixing seal 136 can be configured on the virtual extension line of the fixing member 131. With this structure, when the fixing part motor 133 operates and causes the fixing member 131 to press against the dust collection bin 220, the periphery at the same height of the dust collection bin 220 can be sealed.

[0189] According to an embodiment, the fixing seal 136 can be arranged in a zigzag shape on the dust collection bin guide surface 122 in correspondence with the configuration of the cover opening unit 150 described later.

[0190] Therefore, when the main body 210 of the first vacuum cleaner 200 is disposed at the connecting portion 120, the fixing unit 130 can fix the main body 210 of the first vacuum cleaner 200. Specifically, when the connecting sensor 125 detects that the main body 210 of the first vacuum cleaner 200 is connected to the connecting portion 120 of the vacuum cleaner base station 100, the fixing motor 133 can fix the main body 210 of the first vacuum cleaner 200 by moving the fixing member 131.

[0191] This prevents residual dust from remaining in the dustbin, thus improving the vacuum cleaner's suction power. Furthermore, preventing residual dust from remaining in the dustbin eliminates unpleasant odors caused by residue.

[0192] Below, refer to Figure 2 , Figures 8 to 12 The gate unit 140 of the present invention is described.

[0193] The vacuum cleaner base station 100 of the present invention may include a door unit 140. The door unit 140 may be configured to open and close the dust passage hole 121a.

[0194] The door unit 140 may include a door 141, a door motor 142, and a door arm 143.

[0195] Door 141 can be hinged to mating surface 121, allowing dust to pass through at least a portion of hole 121a when opened and closed.

[0196] In this embodiment, door 141 may include a first door 141a and a second door 141b. The first door 141a and the second door 141b can be combined and form a circular shape overall. Furthermore, door 141, formed by the combination of the first door 141a and the second door 141b, can open and close the dust passage hole 121a.

[0197] The first door 141a may include a first door body 141aa, a hinge portion 141ab, and an arm connection portion 141ac.

[0198] The first door body 141aa can be formed to shield at least a portion of the dust passage hole 121a. As an example, the first door body 141aa can be formed in a shape similar to a portion cut from a disk. Based on the state in which the first door body 141aa shields the dust passage hole 121a, a hinge portion 141ab can be disposed on the upper side of the first door body 141aa, and an arm connecting portion 141ac can be disposed on the lower side of the first door body 141aa.

[0199] The hinge portion 141ab may be a component that hinges the first door 141a to the mating surface 121. The hinge portion 141ab may be disposed at the upper end of the first door body 141aa and may be mated to the mating surface 121.

[0200] The arm joint 141ac can be a component that allows the door arm 143 to be rotatably joined. The arm joint 141ac can be disposed on the lower side of the inner surface of the first door 141a, and the door arm 143 can be rotatably joined. For example, the arm joint 141ac can be formed by extending downward from the lower end of the first door body 141aa, and the end of the second door arm 143b can be rotatably joined.

[0201] The second door 141b can be hinged to the first door 141a to shield at least a portion of dust from passing through the hole 121a.

[0202] The first door 141a and the second door 141b can be rotatably joined at the reference line dividing the first door 141a and the second door 141b. For example, the first door 141a and the second door 141b can be hinged together at the reference line. In this case, the axis on which the first door 141a and the second door 141b are hinged together can be located on the same axis as the axis on which the door arm 143 and the first door 141a are rotatably joined. Furthermore, with the dust passage hole 121a closed as a reference, the first door 141a can be positioned above the dust passage hole 121a, and the second door 141b can be positioned below the dust passage hole 121a. Additionally, the reference line can be formed such that the first door 141a has a larger area than the second door 141b.

[0203] The second door 141b may include a second door body 141ba. The second door body 141ba may be shaped to engage with the first door 141a hingedly and to shield at least a portion of the dust passage hole 121a. For example, the second door body 141ba may be shaped like a portion of a disc being cut off, and a groove may be formed at its upper end to accommodate the arm joint 141ac of the first door 141a.

[0204] Reference Figure 14 The door 141 can be shaped to allow airtight dust passage through the hole 121a. For example, the first door 141a and the second door 141b can be combined and formed into a circular disc shape with a predetermined thickness. In this case, the outer peripheral surface of the door 141, which has a circular disc shape, can be formed by the first door outer wall surface 141ad and the second door outer wall surface 141bb. That is, the first door outer wall surface 141ad can be a surface formed at the outer end of the first door 141a and having an overall arc shape. In addition, the second door outer wall surface 141bb can be a surface formed at the outer end of the second door 141b and having an overall arc shape.

[0205] At this time, the first door outer wall surface 141ad and the second door outer wall surface 141bb can be configured such that the side wall 121b facing the dust passage hole 121a is in the state where the door 141 covers the dust passage hole 121a.

[0206] On the other hand, stop members 141ae and 141bc can be formed by protruding radially outward from the outer wall surface 141ad and / or the outer wall surface 141bb of the first door, respectively. In this case, the maximum diameter of the door 141 including the stop members 141ae and 141bc can be greater than the maximum diameter of the dust passage hole 121a.

[0207] Therefore, the stops 141ae and 141bc can rotate with the door 141 and inside the housing 110 as the door 141 rotates. When the door 141 blocks the dust passage hole 121a, the stops 141ae and 141bc can contact and be supported by the side wall 121b of the dust passage hole 121a, and the door 141 can airtightly seal the dust passage hole 121a.

[0208] With this structure, if the door arm 143 pulls the first door body 141aa when the dust passage hole 121a is closed by the door 141, the first door body 141aa can rotate and move inward toward the vacuum cleaner base station 100 about the hinge portion 141ab, thus opening the dust passage hole 121a. At this time, when the first door body 141aa rotates, the second door body 141ba can droop downward under the action of gravity and rotate in the opposite direction to the rotation direction of the first door body 141aa. That is, when the door 141 is open, the first door 141a and the second door 141b can be in a folded state. This structure has the effect of preventing the door 141 from breaking during the opening process.

[0209] On the other hand, if the door arm 143 pushes the first door body 141aa while the dust passage hole 121a is open, the first door body 141aa can rotate and move outward of the vacuum cleaner base station 100 with the hinge portion 141ab as the axis, so that the dust passage hole 121a is blocked.

[0210] The door motor 142 provides the power to rotate the door 141. Specifically, the door motor 142 can rotate the door arm 143 in a forward or reverse direction. A forward rotation can refer to the direction in which the door arm 143 pulls the door 141. Therefore, when the door arm 143 rotates forward, the dust passage hole 121a can be opened. Conversely, a reverse rotation can refer to the direction in which the door arm 143 pushes the door 141. Therefore, when the door arm 143 rotates in the reverse direction, at least a portion of the dust passage hole 121a can be closed. A forward rotation can be the opposite of a reverse rotation.

[0211] The door arm 143 can connect the door 141 and the door motor 142, and can use the power generated by the door motor 142 to open and close the door 141.

[0212] As an example, door arm 143 may include a first door arm 143a and a second door arm 143b. One end of the first door arm 143a may be coupled to a door motor 142. The first door arm 143a can be rotated by the power of the door motor 142. The other end of the first door arm 143a may be coupled to the second door arm 143b in a rotatable manner. The first door arm 143a can transmit force from the door motor 142 to the second door arm 143b. One end of the second door arm 143b may be coupled to the first door arm 143a. The other end of the second door arm 143b may be coupled to a first door 141a. The second door arm 143b can open or close the dust passage hole 121a by pushing or pulling the first door 141a.

[0213] Door unit 140 may also include door opening / closing detection unit 144 (see reference) Figure 19The door opening and closing detection unit 144 can be installed inside the housing 100 and can detect whether the door 141 is in an open state.

[0214] As one example, the door opening and closing detection unit 144 can be respectively disposed at both ends of the rotational movement area of ​​the door arm 143. As another example, the door opening and closing detection unit 144 can be respectively disposed at both ends of the movement area of ​​the door 141.

[0215] Therefore, when the door arm 143 moves to the preset door open position DP1, or when the door 141 opens to the specified position, the door opening / closing detection unit 144 can detect that the door has been opened. Additionally, when the door arm 143 moves to the preset door closed position DP2, or when the door 141 opens to the specified position, the door opening / closing detection unit 144 can detect that the door has been opened.

[0216] The door opening / closing detection unit 144 may also include a contact sensor. As an example, the door opening / closing detection unit 144 may include a micro switch.

[0217] On the other hand, the door opening and closing detection unit 144 may also include a non-contact sensor. As an example, the door opening and closing detection unit 144 may include an infrared sensor (IR sensor).

[0218] With this structure, the door unit 140 can connect the outer side of the first outer wall surface 112a with the first vacuum cleaner flow path 181 and / or dust collection section 170 by selectively opening and closing at least a portion of the mating surface 121.

[0219] When the exhaust cover 222 of the first vacuum cleaner 200 is opened, the door unit 140 can also be opened. Conversely, when the door unit 140 is closed, the exhaust cover 222 of the first vacuum cleaner 200 can also be closed.

[0220] When removing dust from the dustbin 220 of the first vacuum cleaner 200, the door motor 142 can rotate the door 141 to engage the discharge cover 222 with the dustbin body 221. Specifically, the door motor 142 rotates the door 141 around the hinge portion 141ab, and the door 141, rotating around the hinge portion 141ab, can push the discharge cover 222 toward the dustbin body 221.

[0221] On the other hand, the door unit 140 of one embodiment of the present invention may further include a scraper 145. The scraper 145 may be combined with the door 141, and when the door blocks the dust passage hole 121a, the scraper 145 may contact at least a portion of the flow path pipe 185 forming the flow path portion 180. Later, refer to Figures 13 to 17 The structure and effects of scraper 145 are explained in detail.

[0222] Below, refer to Figure 2 , Figure 5 and Figure 13 The cover opening unit 150 of the present invention is described.

[0223] 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 joint 120 and may open the discharge cover 222 of the first vacuum cleaner 200.

[0224] The cover opening unit 150 may include a push protrusion 151, a cover opening motor 152, a cover opening gear 153, a support plate 154, and a gearbox 155.

[0225] When the first vacuum cleaner 200 is engaged, the push protrusion 151 can be moved to press the engagement lever 222c.

[0226] The push protrusion 151 can be disposed on the dust collection bin guide surface 122. Specifically, a protrusion movement hole can be formed on the dust collection bin guide surface 122, through which the push protrusion 151 can be exposed to the outside.

[0227] The push protrusion 151 can be positioned so that it can press the connecting rod 222c when the first vacuum cleaner 100 is engaged. That is, the connecting rod 222c can be positioned on the protrusion's moving hole. In addition, the connecting rod 222c can be positioned within the moving area of ​​the push protrusion 151.

[0228] The push protrusion 151 can reciprocate linearly to press the connecting rod 222c. Specifically, the push protrusion 151 can be engaged with the gearbox 155 to be guided to move linearly. The push protrusion 151 can be engaged with the cover opening gear 153 and can move together with it by the movement of the cover opening gear 153.

[0229] The cover-opening motor 152 provides the power to move the push protrusion 151. Specifically, the cover-opening motor 152 can rotate the motor shaft (not shown) in a forward or reverse direction. Forward rotation can refer to the direction in which the protrusion 151 pushes the connecting rod 222c. Reverse rotation can refer to the direction in which the push protrusion 151, pressing the connecting rod 222c, returns to its original position. Forward rotation can be the opposite of reverse rotation.

[0230] The cover-opening gear 153 can be engaged with the cover-opening motor 152, and the power of the cover-opening motor 152 can be used to move the push protrusion 151. Specifically, the cover-opening gear 153 can be housed inside the gearbox 155. The drive gear 153a of the cover-opening gear 153 can be engaged with the motor shaft of the cover-opening motor 152 and receive power. The driven gear 153b of the cover-opening gear 153 can be engaged with the push protrusion 151 and move the push protrusion 151. As an example, the driven gear 153b can be configured as a rack and pinion and mesh with the drive gear 153a, and can receive power from the drive gear 153a.

[0231] At this time, a torsion spring 222d can be provided on the discharge cover 222. Through the elastic force of the torsion spring 222d, the discharge cover 222 can rotate more than a predetermined angle and is supported at the rotated position. Therefore, the discharge cover 222 can be opened, allowing communication between the dust passage hole 121a and the interior of the dust collection bin 220.

[0232] The support plate 154 can be configured to support one side of the dust collection bin 220. Specifically, the support plate 154 can extend from the mating surface 121. The support plate 154 can extend from the mating surface 121 toward the center of the dust passage hole 121a (see reference). Figure 6 )

[0233] The gearbox 155 can be disposed inside the housing 110 and can be configured on the lower side of the joint 120 in the direction of gravity, and the cover-opening gear 153 can be accommodated inside the gearbox 155.

[0234] A covered opening detection section 155f may be provided in the gearbox 155 (see reference). Figure 18 In this case, the cover opening detection unit 155f may also include a contact sensor. For example, the cover opening detection unit 155f may include a micro switch. Alternatively, the cover opening detection unit 155f may also include a non-contact sensor. For example, the cover opening detection unit 155f may include an infrared sensor (IR sensor).

[0235] At least one cover opening detection unit 155f may be disposed on the inner or outer side of the gearbox 155. As an example, one cover opening detection unit 155f may be disposed on the inner side of the gearbox 155. In this case, the cover opening detection unit 155f can detect that the push protrusion 151 is in the initial position.

[0236] As another example, two cover opening detection units 155f can also be arranged on the outer side of the gearbox 155. In this case, the cover opening detection unit 155f can detect the initial position of the pushing protrusion 151 and the cover opening position.

[0237] Therefore, according to the present invention, the user can open the dust collection bin 220 through the cover opening unit 150 without having to open the discharge cover 222 of the first vacuum cleaner separately, thereby improving convenience.

[0238] In addition, since the discharge cover 222 is opened when the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100, it has the effect of preventing dust from scattering.

[0239] On the other hand, refer to Figure 2 and Figure 19 Explanation of dust collection section 170.

[0240] The vacuum cleaner base station 100 may include a dust collection unit 170. The dust collection unit 170 may be disposed inside the housing 110. The dust collection unit 170 may be disposed on the lower side of the joint 120 in the direction of gravity.

[0241] As an example, the dust collection unit 170 may refer to a dust bag that collects dust sucked in from inside the dust collection bin 220 of the first vacuum cleaner 200 by the dust collection motor 191.

[0242] The dust collection unit 170 can be attached to the housing 110 in a detachable manner.

[0243] Therefore, the dust collection unit 170 can be discarded after being separated from the housing 110, and a new dust collection unit 170 can be attached to the housing 110. That is, the dust collection unit 170 can be defined as a consumable part.

[0244] The dust bag can be configured to increase in volume and contain dust when the dust collection motor 200 generates suction. For this purpose, the dust bag can be made of a material that allows air to pass through but prevents foreign objects such as dust from passing through. For example, the dust bag can be made of non-woven fabric and can have a hexahedral shape based on its increased volume.

[0245] Therefore, users do not need to separately tie up bags to collect dust, thus improving user convenience.

[0246] On the other hand, the vacuum cleaner base station 100 of this embodiment may also include a sterilization module 175.

[0247] The sterilization module 175 can be disposed on the flow path section 180, or at least one can be disposed around the dust collection section 170.

[0248] The sterilization module 175 is a structure for sterilizing the dust collected in the dust collection section 170. The sterilization module 175 may include: a light source that emits sterilizing light; and a protective panel disposed below the light source to protect the light source.

[0249] Here, the light source may include at least one light-emitting diode (LED) capable of emitting germicidal light with the ability to kill bacteria. The germicidal light emitted by the light source may have different wavelengths depending on the type of LED.

[0250] As an example, a light source could be a light-emitting diode that emits ultraviolet light in the UV-C wavelength range. Based on wavelength, ultraviolet light can be divided into UV-A (315nm–400nm), UV-B (280nm–315nm), and UV-C (200nm–280nm). Ultraviolet light in the UV-C region can damage the DNA double helix of microorganisms, inhibiting their proliferation.

[0251] Alternatively, as another example, the light source could be a light-emitting diode (LED) that emits visible light with a wavelength of 405 nm. Blue light with a wavelength of 405 nm falls within the boundary region of visible light and ultraviolet light, and its bactericidal ability has been proven.

[0252] A protective panel can be positioned below the light source at a predetermined distance to prevent damage. In this case, the protective panel can be made of a material that maximizes the transmittance of the light source. For example, the protective panel can be made of quartz. Quartz is known to not obstruct the transmission of ultraviolet light in the UV-C region.

[0253] The vacuum cleaner base station 100 of this embodiment of the invention prevents the proliferation of bacteria in the dust collection section 170 by providing a sterilization module 175 for sterilization, thereby enabling hygienic management of the dust collection section 170, which stores inhaled dust for a long time.

[0254] On the other hand, the vacuum cleaner base station 100 may also include a side door (not shown). The side door may be configured in the housing 110. The side door allows the dust collection section 170 to be selectively exposed to the outside. Thus, the user can easily remove the dust collection section 170 from the vacuum cleaner base station 100.

[0255] On the other hand, refer to Figure 2 , Figure 12 as well as Figure 19 Explanation of flow path section 180.

[0256] The vacuum cleaner base station 100 may include a flow path section 180. The flow path section 180 can connect the dust collection section 170 to the first vacuum cleaner 200 or the second vacuum cleaner 300.

[0257] The flow path section 180 may include a first vacuum cleaner flow path section 181, a second vacuum cleaner flow path section 182, and a flow path switching valve 183.

[0258] The first vacuum cleaner flow path 181 can connect the dust collection bin 220 and the dust collection section 170 of the first vacuum cleaner 200. The first vacuum cleaner flow path 181 can be disposed on the rear side of the mating surface 121. The first vacuum cleaner flow path 181 can refer to the space between the dust collection bin 220 and the dust collection section 170 of the first vacuum cleaner 200. The first vacuum cleaner flow path 181 can be a space formed rearward from the dust passage hole 121a, and can be a flow path formed by bending downward from the dust passage hole 121a to allow dust and air to flow.

[0259] Specifically, the first vacuum cleaner flow path 181 may include: a first flow path 181a, which communicates with the internal space of the dust collection bin 220 when the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100 and dust is open through the hole 121a; and a second flow path 181b, which communicates the first flow path 181a and the internal space of the dust collection section 170.

[0260] As an example, the first flow path 181a can be substantially parallel to the suction motor axis a1 or the dust collection bin through line a5. In this case, the suction motor axis a1 or the dust collection bin through line a5 can pass through the first flow path 181a. That is, when the first vacuum cleaner 200 and the vacuum cleaner base station 100 are combined, the longitudinal axis of the dust collection bin 220 can pass through the first flow path 181a.

[0261] Furthermore, the second flow path 181b can be configured in a direction parallel to the axis C of the dust collection motor. That is, the longitudinal axis of the vacuum cleaner base station 100 can pass through the second flow path 181b. With this structure, the reduction in suction power of the dust collection motor 181 in the first flow path 181a and the second flow path 181b can be minimized.

[0262] At this time, the first flow path 181a can form a predetermined angle with the second flow path 181b. For example, the first flow path 181a and the second flow path 181b can form a right angle. Therefore, when the first vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the longitudinal axis of the dust collection bin 220 and the longitudinal axis of the vacuum cleaner base station 100 can intersect each other. With this structure, the overall volume of the vacuum cleaner base station 100 can be minimized.

[0263] On the other hand, the length of the first flow path 181a can be less than or equal to the length of the second flow path 181b. With such a structure, even if the overall flow path for removing dust is formed into a shape with one bend, the suction force of the dust collection motor 191 can be transmitted to the space inside the dust collection bin 220.

[0264] Dust in the dust collection bin 220 of the first vacuum cleaner 200 can move to the dust collection section 170 via the flow path section 181 of the first vacuum cleaner.

[0265] The second vacuum cleaner flow path 182 can connect the second vacuum cleaner 300 and the dust collection section 170. Dust in the second vacuum cleaner 300 can move to the dust collection section 170 via the second vacuum cleaner flow path 182.

[0266] A flow path switching valve 183 can be disposed between the dust collection section 170 and the first vacuum cleaner flow path section 181 and the second vacuum cleaner flow path section 182. The flow path switching valve 183 can selectively open and close the first vacuum cleaner flow path section 181 and the second vacuum cleaner flow path section 182 connected to the dust collection section 170. This prevents a decrease in suction power caused by the opening of multiple flow paths 181 and 182.

[0267] For example, when only the first vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the flow path switching valve 183 can connect the flow path section 181 of the first vacuum cleaner and the dust collection section 170, and can disconnect the connection between the flow path section 182 of the second vacuum cleaner and the dust collection section 170.

[0268] On the other hand, in this embodiment, the flow path 180 can be formed inside the flow path pipe 185. In this case, the flow path pipe 185 can refer to a pipe disposed inside the housing 110. The flow path pipe 185 can include a first flow path pipe 185a and a second flow path pipe 185b. In this case, the first flow path pipe 185a can form a first flow path 181a internally, and the second flow path pipe 185b can form a second flow path 181b internally. Furthermore, the first flow path pipe 185a and the second flow path pipe 185b can be divided by the bypass hole 122c. That is, the flow path pipe 185 disposed above the bypass hole 122c in the gravity direction can be called the first flow path pipe 185a, and the flow path pipe 185 disposed below the bypass hole 122c in the gravity direction can be called the second flow path pipe 185b.

[0269] On the other hand, when the dust collection motor 191 is running and dust and foreign objects inside the dust collection bin 220 are sucked into the vacuum cleaner base station 100, foreign objects such as hair may become entangled or adhere to the periphery of the mating surface 121 or the side wall 121b of the dust passage hole 121a or the inner circumferential surface of the first flow path pipe 185a due to static electricity.

[0270] Therefore, foreign matter remaining around the mating surface 121 or on the side wall 121b of the dust passage hole 121a or the inner circumferential surface of the first flow path pipe 185a is difficult to remove. In order to remove these foreign matter, users may encounter the inconvenience of needing to use wet wipes or the like to directly remove these foreign matter.

[0271] Furthermore, the continuous accumulation of foreign objects may produce an unpleasant odor, and the obstruction of airflow by hair and other debris can lead to flow loss. Additionally, the presence of foreign objects in the user's field of vision can cause unpleasant problems.

[0272] To address this issue, a vacuum cleaner base station 100 according to an embodiment of the present invention can remove foreign objects by providing a scraper 145 in the door unit 140.

[0273] Scraper 145 will be explained in detail later.

[0274] On the other hand, refer to Figure 2 and Figure 19 Description of dust suction module 190.

[0275] 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 192, and a second filter (not shown).

[0276] The dust collection motor 191 can be disposed at the lower part of the dust collection section 170. The dust collection motor 191 can generate suction in the first vacuum cleaner flow path section 181 and the second vacuum cleaner flow path section 182. Thus, the dust collection motor 191 can provide suction to draw dust from the dust collection bin 220 of the first vacuum cleaner 200 and dust from the second vacuum cleaner 300.

[0277] The dust collection motor 191 can generate suction by rotating. As an example, the dust collection motor 191 can be formed into a shape similar to a cylinder.

[0278] On the other hand, in this embodiment, a virtual dust collection motor axis C extending along the rotation axis of the dust collection motor 191 can be formed.

[0279] The first filter 192 can be configured between the dust collection section 170 and the dust collection motor 191. The first filter 192 can be a pre-filter.

[0280] A second filter (not shown) may be configured between the dust collection motor 191 and the outer wall surface 112. The second filter (not shown) may be a high-efficiency particulate air (HEPA) filter.

[0281] on the other hand, Figure 19 This is a block diagram illustrating the control configuration in a vacuum cleaner base station according to an embodiment of the present invention.

[0282] Reference Figure 19 This section explains the control configuration of the vacuum cleaner base station 100 of the present invention.

[0283] The vacuum cleaner base station 100 of this embodiment may further include a control unit 400 comprising a control connection part 120, a fixing unit 130, a door unit 140, a cover opening unit 150, a dust collection part 170, a flow path part 180, and a dust suction module 190.

[0284] The control unit 400 may consist of a printed circuit board and components mounted on the printed circuit board.

[0285] If the coupling sensor 125 detects the coupling of the first vacuum cleaner 200, the coupling sensor 125 can send a signal indicating that the first vacuum cleaner 200 is coupled to the coupling part 120. At this time, the control unit 400 can receive the signal from the coupling sensor 125 and determine that the first vacuum cleaner 200 is coupled to the coupling part 120.

[0286] Furthermore, if the charging unit 128 supplies power to the battery 240 of the first vacuum cleaner 200, the control unit 400 can determine that the first vacuum cleaner 200 is connected to the connection unit 120.

[0287] If it is determined that the first vacuum cleaner 200 is connected to the connecting part 120, the control part 400 can fix the first vacuum cleaner 200 by running the fixing part motor 133.

[0288] If the fixing member 131 or the fixing link 135 moves to the predetermined fixing position FP1, the fixing detection unit 137 can send a signal indicating that the first vacuum cleaner 200 is fixed. The base station control unit 400 can receive the signal indicating that the first vacuum cleaner 200 is fixed from the fixing detection unit 137 and determine that the first vacuum cleaner 200 is fixed. If it is determined that the first vacuum cleaner 200 is fixed, the base station control unit 400 can interrupt the operation of the fixing motor 133.

[0289] On the other hand, once the dust collection bin 200 is emptied, the control unit 400 can release the first vacuum cleaner 200 by rotating the fixing unit motor 133 in the opposite direction.

[0290] If it is determined that the first vacuum cleaner 200 is fixed to the joint 120, the control unit 400 can open the door 141 of the vacuum cleaner base station 100 by operating the door motor 142.

[0291] If door 141 or door arm 143 reaches the designated open position DP1, the door opening / closing detection unit 144 can send a signal indicating that door 141 is open. The control unit 400 can receive the signal indicating that door 141 is open from the door opening / closing detection unit 137 and determine that door 141 is open. If it is determined that door 141 is open, the control unit 400 can interrupt the operation of door motor 142.

[0292] On the other hand, once the dust collection bin 200 has been emptied, the control unit 400 can close the door 141 by rotating the door motor 142 in the opposite direction.

[0293] If it is determined that the door 141 is open, the control unit 400 can open the discharge cover 222 of the first vacuum cleaner 200 by activating the cover opening motor 152.

[0294] If the protrusion 151 is pushed to the designated open position CP1, the cover opening detection unit 155f can send a signal indicating that the discharge cover 222 has been opened. The control unit 400 can receive the signal indicating that the discharge cover 222 has been opened from the cover opening detection unit 155f and determine that the discharge cover 222 has been opened. If it is determined that the discharge cover 222 has been opened, the control unit 400 can interrupt the operation of the cover opening motor 152.

[0295] The control unit 400 can control the sterilization module 175. For example, the control unit 400 can operate the sterilization module 175 after dust is captured in the dust collection unit 170 or at a predetermined time interval to sterilize viruses or microorganisms present inside or outside the dust collection unit 170.

[0296] The control unit 400 can control the flow path switching valve 183 of the flow path section 180. As an example, the control unit 400 can selectively open and close the first vacuum cleaner flow path section 181 and the second vacuum cleaner flow path section 182.

[0297] The control unit 400 can draw in dust from inside the dust collection bin 220 by driving the dust collection motor 191.

[0298] The control unit 400 can display the dustbin emptying status and charging status of the first vacuum cleaner 200 or the second vacuum cleaner 300 by activating the display unit 410.

[0299] On the other hand, the vacuum cleaner base station 100 of the present invention may include a display unit 410.

[0300] The display unit 410 can be configured not only in the housing 110, but also in a separate display device, or in a terminal including a mobile phone.

[0301] 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. Users can easily grasp the status of the currently executing program, remaining time, etc., through the information output by the display unit.

[0302] On the other hand, the vacuum cleaner base station 100 in this embodiment of the invention may include a memory 430. The memory 430 may include various data for driving and operating the vacuum cleaner base station 100.

[0303] On the other hand, the vacuum cleaner base station 100 of this embodiment may include an input unit 440. The input unit 440 generates key input data input by the user to control the operation of the vacuum cleaner base station 100. For this purpose, the input unit 440 may be composed of a keypad, a dome switch, a touchpad (static / electrostatic), etc. In particular, when the touchpad and the display unit 410 form a stacked structure, it may be referred to as a touch screen.

[0304] On the other hand, refer to Figure 2 and Figure 3 This indicates the combined state of the first vacuum cleaner 200 and the vacuum cleaner base station 100.

[0305] In this invention, the first vacuum cleaner 200 can be placed on the outer wall surface 112 of the vacuum cleaner base station 100. As an example, the dust collection bin 220 and battery housing 230 of the first vacuum cleaner 200 can be coupled to the coupling surface 121 of the vacuum cleaner base station 100. That is, the first vacuum cleaner 200 can be placed on the first outer wall surface 112a.

[0306] At this time, the suction motor axis a1 can be formed perpendicular to the first outer wall surface 112a. That is, the suction motor axis a1 can be formed parallel to the ground. The suction motor axis a1 can be formed on a plane perpendicular to the ground. Alternatively, the suction motor axis a1 can be formed on a plane that intersects the first outer wall surface 112a perpendicularly.

[0307] The suction flow path a2 can be formed parallel to the first outer wall surface 112a. The suction flow path a2 can be formed along the direction of gravity. That is, the suction flow path a2 can be formed perpendicular to the ground. Alternatively, the suction flow path a2 can be formed on a plane that intersects the first outer wall surface 112a perpendicularly.

[0308] The grip through line a3 can be formed at a predetermined angle to the first outer wall surface 112a. Alternatively, the grip through line a3 can be formed at a predetermined angle to the ground. The grip through line a3 can also be formed on a plane that intersects the first outer wall surface 112a perpendicularly.

[0309] The swirl line a4 can be formed perpendicular to the first outer wall surface 112a. That is, the swirl line a4 can be formed parallel to the ground. The swirl line a4 can be formed on a plane perpendicular to the ground. Alternatively, the swirl line a4 can be formed on a plane that intersects the first outer wall surface 112a perpendicularly.

[0310] The dust collection bin through line a5 can be formed perpendicular to the first outer wall surface 112a. That is, the dust collection bin through line a5 can be formed parallel to the ground. The dust collection bin through line a5 can be formed on a plane perpendicular to the ground. Alternatively, the dust collection bin through line a5 can be formed on a plane that intersects the first outer wall surface 112a perpendicularly.

[0311] The dust collection motor shaft C can be formed perpendicular to the ground. The dust collection motor shaft C can be formed parallel to at least one of the first outer wall surface 112a, the second outer wall surface 112b, the third outer wall surface 112c, and the fourth outer wall surface 112d.

[0312] When the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100, the suction motor axis a1 can intersect the longitudinal axis of the vacuum cleaner base station 100. That is, the rotation axis of the suction motor 214 can intersect the longitudinal axis of the vacuum cleaner base station 100.

[0313] When the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100, the suction motor axis a1 can intersect with the dust collection motor axis C.

[0314] When the first vacuum cleaner 200 and the vacuum cleaner base station 100 are combined, the suction motor axis a1 can intersect the dust collection motor axis C at a specified angle. As an example, the included angle θ1 between the suction motor axis a1 and the dust collection motor axis C can be more than 40 degrees and less than 95 degrees.

[0315] The included angle can be the angle formed by the intersection of the suction motor axis a1 and the dust collection motor axis C, or it can refer to the angle between the suction motor axis a1 and the dust collection motor axis C.

[0316] On the other hand, when the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100, the handle 216 can be positioned further away from the suction motor axis a1 relative to the ground. With this structure, when the user holds the handle 216, the relatively heavy suction motor 214 is located on the lower side in the direction of gravity, so the user can attach or detach the first vacuum cleaner 200 from the vacuum cleaner base station 100 with a simple action of moving the first vacuum cleaner 200 in a direction parallel to the ground, thus providing convenience.

[0317] Furthermore, when the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100, the battery 240 can be positioned further away from the suction motor axis a1, with the ground as a reference. With this structure, the first vacuum cleaner 200 can be stably supported by the vacuum cleaner base station 100.

[0318] When the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100, the suction flow path a2 can be formed parallel to the dust collection motor axis C. With this structure, the first vacuum cleaner 200, when attached to the vacuum cleaner base station 100, has the effect of minimizing the space occupied on the horizontal plane.

[0319] At this time, a connecting portion 120 can be arranged between the suction flow path a2 and the dust collection motor axis C. A fixing member 131 can be arranged between the suction flow path a2 and the dust collection motor axis C. A cover opening unit 150 can be arranged between the suction flow path a2 and the dust collection motor axis C. With this structure, the user can easily connect or disconnect the first vacuum cleaner 200 from the vacuum cleaner base station 100 by simply moving the first vacuum cleaner 200 in a direction parallel to the ground, and can fix and open the dust collection bin 220, thus providing convenience.

[0320] The through line a3 of the grip portion can intersect the axis C of the dust collection motor at a predetermined angle. At this time, the intersection point P6 of the through line a3 of the grip portion and the axis C of the dust collection motor can be located inside the housing 110. With this structure, when the user is holding the first vacuum cleaner 200, the first vacuum cleaner 200 can be attached to the vacuum cleaner base station 100 with a simple action of pushing the arm towards the side of the vacuum cleaner base station 100. Furthermore, since the relatively heavy dust collection motor 191 is housed inside the housing 110, even if the user forcefully pushes the first vacuum cleaner 200 into the vacuum cleaner base station 100, the vacuum cleaner base station 100 can be prevented from shaking.

[0321] When the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100, the vortex line a4 can intersect the longitudinal axis of the vacuum cleaner base station 100. That is, the flow axis of the dust separation section 213 can intersect the longitudinal axis of the vacuum cleaner base station 100. At this time, the intersection point of the flow axis of the dust separation section 213 and the longitudinal axis of the vacuum cleaner base station 100 can be located inside the housing 110, and more specifically, inside the flow path section 180.

[0322] When the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100, the swirl line a4 can intersect with the dust collection motor axis C. At this time, the intersection of the swirl line a4 and the dust collection motor axis C can be located inside the housing 110, and more specifically, inside the flow path section 180. With this structure, the first vacuum cleaner 200 can be stably supported by the vacuum cleaner base station 100 when it is attached to the vacuum cleaner base station 100, and flow path loss is reduced during the emptying of the dust collection bin 220.

[0323] When the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100, the dust collection bin through line a5 can intersect the length axis of the vacuum cleaner base station 100. That is, the length axis of the dust collection bin 220 can intersect the length axis of the vacuum cleaner base station 100. At this time, the intersection point of the length axis of the dust collection bin 220 and the length axis of the vacuum cleaner base station 100 can be located inside the housing 110, and more specifically, it can be located inside the flow path section 180.

[0324] On the other hand, when the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100, the handle 216 can be positioned further away from the dustbin through line a5, with the ground as a reference. With this structure, when the user holds the handle 216, the user can attach or detach the first vacuum cleaner 200 from the vacuum cleaner base station 100 with a simple action of moving the first vacuum cleaner 200 in a direction parallel to the ground, thus providing convenience.

[0325] Furthermore, when the first vacuum cleaner 200 is attached to the vacuum cleaner base station 100, the battery 240 can be positioned further away from the dustbin through line a5, with the ground as the reference point. With this structure, the battery 240 can press down on the main body 210 of the first vacuum cleaner 200 under its own weight, thus ensuring the first vacuum cleaner 200 is stably supported on the vacuum cleaner base station 100.

[0326] on the other hand, Figure 14 A cross-sectional perspective view is shown illustrating the state in which a door in a vacuum cleaner base station, according to an embodiment of the present invention, blocks dust from passing through a hole. Figure 15 This shows a different perspective. Figure 14 The image.

[0327] Reference Figure 11 , Figure 12 , Figure 14 as well as Figure 15 This describes a scraper according to an embodiment of the present invention.

[0328] The scraper 145 can be combined with the outer wall surface 141bb of the second door, and can be formed by protruding radially outward from the outer wall surface 141bb of the second door. Therefore, when the door 141 is shielding the dust passage hole 121a, the second door 141b can be positioned below the first door 141a, and the scraper 145 can be provided by protruding downward from the second door 141b.

[0329] At this time, the protruding length of the scraper 145 can be greater than the distance between the outer wall surface 141bb of the second door and the first flow path pipe 185a. Therefore, when the door 141 is closed and the door 141 blocks the dust passage hole 121a, the scraper 145 can contact at least a portion of the first flow path pipe 185a. In addition, the scraper 145 can generate friction with the inner circumferential surface of the first flow path pipe 185a.

[0330] Specifically, the scraper 145 may include a door joint 145a, a first scraper 145b, and a second scraper 145c.

[0331] The door joint 145a can be joined along the outer peripheral surface of the door 141. Specifically, the door joint 145a can be formed in an arc shape and joined along the outer wall surface 141bb of the second door. A first scraper 145b and a second scraper 145c, described later, can be formed protrudingly in the door joint 145a.

[0332] The first scraper 145b can be formed by protruding radially outward from the door joint 145a. For example, the first scraper 145b can be formed with a shape in which its width becomes narrower the further away from the door joint 145a it is. That is, the first scraper 145b can be a rib with a triangular cross-section. With such a structure, it is possible to easily remove foreign objects that are tangled or attached to the scraper 145 due to static electricity during the process of scraping foreign objects out by the scraper 145.

[0333] The second scraper 145c can be formed by protruding radially outward from the door joint 145a. In this case, the second scraper 145c can be formed protruding side-by-side with the first scraper 145b. For example, the second scraper 145c can be formed with a shape where its width narrows as it moves further away from the door joint 145a. That is, the second scraper 145c can be a rib with a triangular cross-section.

[0334] On the other hand, the scraper 145 can be formed of an elastic material. In this embodiment, rubber is used as the material for the scraper 145, but it is not limited to this. Various materials that can elastically deform when the scraper 145 contacts the first flow path tube 185a and can generate friction between the scraper 145 and the first flow path tube 185a can be used.

[0335] On the other hand, at this time, the first scraper 145b can be configured closer to the dust passage hole 121a than the second scraper 145c. That is, the first scraper 145b can be configured closer to the stop 141bc of the second door 141b than the second scraper 145c.

[0336] Therefore, when the door 141 blocks the dust passage hole 121a, the area deformed by the first scraper 145b in contact with the first flow path tube 185a can be different from the area deformed by the second scraper 145c due to the first flow path tube 185a. For example, the first flow path tube 185a can form a continuous surface with the sidewall of the dust passage hole 121a. In this case, the first flow path tube 185a can be formed to be inclined downward from the dust passage hole 121a at a predetermined angle. Therefore, the area of ​​compression or friction between the first scraper 145b and the first flow path tube 185a can be greater than the area of ​​compression or friction between the second scraper 145c and the first flow path tube 185a. Conversely, the stop 141bc contacts the sidewall 121b of the dust passage hole 121a, but the frictional force generated is smaller. That is, the frictional force between the scraper 145 and the inner circumferential surface of the first flow path pipe 185a can be greater than the frictional force between the stop 141bc and the sidewall 121b of the dust passage hole 121a. With this structure, the scraper 145 can function like a rubber broom. Foreign matter, including hair remaining on the inner circumferential surface of the dust passage hole 121a and the first flow path pipe 185a, can be scraped away by the scraper 145 during the opening and closing of the door 141.

[0337] on the other hand, Figure 16 A cross-sectional perspective view is shown illustrating the state in which a door in a vacuum cleaner base station, according to a second embodiment of the present invention, blocks dust from passing through a hole.

[0338] Reference Figure 11 , Figure 12 as well as Figure 16 The scraper 1145 of the second embodiment of the present invention is described below.

[0339] On the other hand, to avoid repetitive explanations, except for the content specifically described in this embodiment, the structure and effect of the scraper 145 of the vacuum cleaner base station of an embodiment of the present invention can be referred to.

[0340] The scraper 1145 in this embodiment may further include a blade 1145d disposed between the first scraper 1145b and the second scraper 1145c.

[0341] Blade 1145d can cut foreign objects such as hair. Specifically, the tip of blade 1145d can be sharpened to cut foreign objects such as hair. Furthermore, blade 1145d can be formed from materials such as metal, resin, or silicon that can form a sharp cutting edge.

[0342] With this structure, foreign matter remaining on the inner circumferential surface of the dust passage hole 121a and the first flow path tube 185a can be cut by the blade 1145d. Therefore, according to this embodiment, entanglement of foreign matter such as hair can be prevented, and it can be removed by the scraper 1145 without leaving any residue on the dust collection bin 220, the side wall 121b of the dust passage hole 121a, or the inner circumferential surface of the first flow path tube 185a.

[0343] Furthermore, in this embodiment, the blade 1145d is disposed between the first scraper 1145b and the second scraper 1145c, and the blade 1145d can be elastically supported by the elastic force of the first scraper 1145b and the second scraper 1145c. Therefore, it is possible to prevent the first flow path tube 185a from being damaged due to excessive pressure of the blade 1145d on the inner circumferential surface of the first flow path tube 185a.

[0344] On the other hand, in this embodiment, the second scraper 1145c may include a plurality of scraping teeth 1145ca protruding side by side at predetermined intervals along the outer peripheral surface of the door 141. That is, in this embodiment, the second scraper 1145c may have spaced spaces between the plurality of scraping teeth 1145ca. With such a structure, the friction between the second scraper 1145c and the first flow path tube 185a can be reduced. In addition, it is possible to prevent the blade 1145d from being interfered with by the second scraper 1145c when cutting foreign objects such as hair.

[0345] on the other hand, Figure 17 A cross-sectional view is shown illustrating the state in which a door in a vacuum cleaner base station according to a third embodiment of the present invention blocks dust from passing through a hole.

[0346] Reference Figure 11 , Figure 12 as well as Figure 17 The scraper 2145 of the third embodiment of the present invention is described below.

[0347] On the other hand, to avoid repetitive explanations, except for the content specifically described in this embodiment, the structure and effect of the scraper 145 of the vacuum cleaner base station of an embodiment of the present invention can be referred to.

[0348] In this embodiment, the scraper 2145 may be a hollow gasket. Specifically, the scraper 2145 may include a door joint portion 2145a, a friction portion 2145b, and a connecting portion 2145c.

[0349] The door joint 2145a can be joined along the outer peripheral surface of the door 141. Specifically, the door joint 145a can be formed in an arc shape and joined along the outer wall surface 141bb of the second door. A connecting portion 2145c can be formed protrudingly in the door joint 145a.

[0350] With the door 141 shielding the dust passage hole 121a, the friction part 2145b can rub against the flow path pipe 185.

[0351] The connecting portion 2145c can be formed to connect the door joint portion 2145a and the friction portion 2145b, and a space can be formed inside the scraper 2145 surrounded by the door joint portion 2145a, the friction portion 2145b, and the connecting portion 2145c. With this structure, the scraper 2145 can be compressed during contact with and pressing of the first flow path tube 185a, and the friction between the scraper 2145 and the first flow path tube 185a can be increased. Therefore, according to this embodiment, the increased friction between the scraper 2145 and the first flow path tube 185a improves the effect of scraping out foreign objects and enhances the sealing effect of the door 141.

[0352] on the other hand, Figure 18 A cross-sectional view is shown illustrating the state in which a door in a vacuum cleaner base station according to a fourth embodiment of the present invention blocks dust from passing through a hole.

[0353] Reference Figure 11 , Figure 12 as well as Figure 18 This describes the scraper 3145 of the fourth embodiment of the present invention.

[0354] On the other hand, to avoid repetitive explanations, except for the content specifically described in this embodiment, the structure and effect of the scraper 145 of the vacuum cleaner base station of an embodiment of the present invention can be referred to.

[0355] In this embodiment, the scraper 3145 can be configured to sweep away foreign objects such as hair while rubbing against the inner circumferential surface of the first flow path tube 185a. For example, in this embodiment, the scraper 3145 can be a brush disposed along the outer wall surface 3141bb of the second door. As one example, the brush can be formed of bristles. As another example, the brush can be formed of felt material. With such a structure, when the door 141 is open, the scraper 3145 can sweep foreign objects toward the dust collection section 170. Subsequently, if the dust collection motor 191 is operated, the foreign objects can be captured in the dust collection section 170. Therefore, according to this embodiment, it has the advantage of minimizing damage caused by friction between the scraper 3145 and the first flow path tube 185a.

[0356] On the other hand, the operation and effect of the scraper of the vacuum cleaner base station of the present invention will be explained.

[0357] First, when the dust collection bin 220 is fixed to the vacuum cleaner base station 100, the door 141 of the vacuum cleaner base station 100 can be opened.

[0358] Specifically, if the fixing detection unit 137 receives a signal indicating that the dust collection bin 220 is fixed, the control unit 400 can rotate the door motor 142 in the forward direction to rotate the door 141, allowing dust to open through the hole 121a. That is, the control unit 400 can rotate the door 141 to allow dust to open through the hole 121a.

[0359] Furthermore, as the discharge cover 222 of the dust collection bin 220 rotates, the space inside the dust collection bin body 221 opens, and as the door 141 rotates, dust is opened through the hole 121a, thereby allowing the internal space of the dust collection bin 220 to connect with the flow path 180 (specifically, the first vacuum cleaner flow path 181) of the vacuum cleaner base station 100.

[0360] At this time, the scraper 145 can rotate together with the door 141 while generating friction with the first flow path pipe 185a. Furthermore, the scraper 145 can remove foreign matter remaining on the inner circumferential surface of the dust passage hole 121a and / or the first flow path pipe 185a. That is, during the opening of the door 141, the scraper 145 can sweep foreign matter towards the dust collection section 170.

[0361] On the other hand, during this process, foreign objects may become entangled or adhere to the scraper 145 due to static electricity.

[0362] In this case, if the dust collection motor 191 operates, the dust inside the dust collection bin 220 is sucked into the dust collection section 170, thereby removing the dust inside the dust collection bin 220. In addition, the foreign matter remaining on the scraper 145 can also be removed by the suction generated in the dust collection motor 191.

[0363] Therefore, according to the present invention, it has the effect of removing foreign matter remaining on the first vacuum cleaner flow path 181, including the dust passage hole 121a and / or the first flow path tube 185a, by operating the dust collection motor 191 while the door 141 is open.

[0364] On the other hand, unlike this, the door 141 can also be opened while the dust collection motor 191 is running. In this case, the suction generated in the dust collection motor 191 acts on the first vacuum cleaner flow path 181, so foreign objects on the first vacuum cleaner flow path 181 can be captured and collected in the dust collection section 170 while being scraped by the scraper 145.

[0365] On the other hand, if the door 141 closes the dust passage hole 121a, the scraper 145 can scrape off the foreign matter remaining on the inner circumferential surface of the first flow path pipe 185a.

[0366] Furthermore, the vacuum cleaner base station 100 of the present invention can operate the dust collection motor 191 with the dust passage hole 121a blocked by the door 141. In this case, the dust passage hole 121a is closed, so no dust accumulates inside the dust collection bin 220. However, due to the negative pressure generated by the operation of the dust collection motor 191, dust and other particles remaining around the dust collection bin 220 can be sucked into the dust collection section 170 via the bypass flow path. At this time, foreign objects remaining in the first flow path pipe 185a or the scraper 145 can be sucked into the dust collection section 170.

[0367] In particular, when a blade 1145d is provided on the scraper 1145 as in the second embodiment of the present invention, the blade 1145d can be used to cut foreign objects such as hair during the process of closing the dust passage hole 121a of the door 141, thereby preventing foreign objects from tangling or accumulating.

[0368] On the other hand, the vacuum cleaner base station 100 of the present invention can block the dust passage hole 121a with the door 141 while the dust collection motor 191 is running. In this case, the flow rate sucked in by the dust collection motor 191 is constant, but the flow rate can increase as the area of ​​the dust passage hole 121a decreases. Through such a change in flow rate, foreign matter remaining inside the dust collection bin 220, around the dust passage hole 121a, and in the first flow path pipe 185a can be captured and collected in the dust collection section 170.

[0369] On the other hand, the vacuum cleaner base station 100 of the present invention can rotate the door 141 to open at least a portion of the dust passage hole 121a after the dust collection motor 191 has finished operating, and then cover it again.

[0370] This is to prevent dust from slightly opening through the hole 121a. Therefore, by closing the door 141 again to block the dust passage hole 121a after the dust collection motor 191 has finished running, it is possible to prevent backflow of dust that may be present on the flow path 180. At this time, the scraper 145 can also remove foreign objects, including hair, remaining in the dust passage hole 121a and / or the first flow path tube 185a while rotating together with the door 141.

[0371] The above description, through specific embodiments of the present invention, is only for illustrating the present invention. The present invention is not limited thereto, and obviously, the present invention can be modified or improved by those skilled in the art.

[0372] Simple variations or modifications of this invention are all within the scope of this invention, and the specific scope of protection of this invention will be further clarified by the scope of the appended claims.
