Description

Technical Field

[0001] This invention relates to a vacuum cleaner base station, and more specifically, to a vacuum cleaner base station that can automatically open and close the dust bin lid of the vacuum cleaner and collect the dust inside the dust bin when the vacuum cleaner is in use. Background Technology

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

[0003] Vacuum cleaners can be categorized into manual vacuum cleaners, where the user directly moves the vacuum cleaner to perform cleaning, and automatic vacuum cleaners, which move autonomously to perform cleaning. Manual vacuum cleaners can be further classified according to their form factor, such as canister vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick vacuum cleaners.

[0004] In the past, canister vacuum cleaners were widely used in household vacuum cleaners. In recent years, the trend has been towards the widespread use of handheld and stick vacuum cleaners, which integrate the dustbin and the vacuum cleaner body, thus improving ease of use.

[0005] In a canister vacuum cleaner, the main body and the suction port are connected by a rubber hose or tube, and a brush can be inserted into the suction port and used, depending on the situation.

[0006] Handheld vacuum cleaners maximize portability; while lightweight, their shorter length limits the cleaning area when used while seated. Therefore, they are best suited for cleaning specific areas such as desks, sofas, or inside cars.

[0007] Stick vacuum cleaners can be used upright, eliminating the need to bend over. This makes them advantageous for moving around and cleaning wider areas. While handheld vacuum cleaners are better suited for narrower spaces, stick vacuum cleaners can clean wider areas and reach higher, harder-to-reach areas. In recent years, stick vacuum cleaners have been offered in modular form, allowing for proactive changes in vacuum cleaner type and use for a wider variety of cleaning tasks.

[0008] However, in existing handheld and stick vacuum cleaners, the small capacity of the dustbin for storing collected dust creates the inconvenience of users having to empty the dustbin each time.

[0009] In addition, when the dustbin is emptied, the dust will scatter, which may pose a health risk to users.

[0010] In addition, if the residual dust in the dustbin is not removed, the suction power of the vacuum cleaner will decrease.

[0011] In addition, if the residual dust in the dust bin is not removed, there is a problem of the residue producing an odor.

[0012] As an existing patent document, Korean Patent Publication No. 10-2020-0074001 discloses a docking dust collector base station that can be combined with a dust bin of a vacuum cleaner to empty the dust bin.

[0013] In the docking dust collector base station, the user opens the dust bin by pressing it against the docking dust collector base station to increase the bonding force.

[0014] In this case of docking with the dust collector base station, there is an inconvenience that the dust can needs to be separated from the vacuum cleaner before it can be docked with the dust collector base station.

[0015] Additionally, there is a limitation: regardless of dust collection in the dust bin, when the dust bin is attached to the docking dust collector base station, the vacuum cleaner's dust bin needs to remain open. In this case, the following limitation exists: when the user separates the dust bin, any remaining dust will scatter from the open dust bin.

[0016] Korean Patent Publication No. 10-2021-0019940 discloses a vacuum cleaner base station that can automatically empty the dust bin of a vacuum cleaner when it is connected.

[0017] The existing patent documents disclose a structure in which a connecting rod is pressed when the vacuum cleaner is attached to a vacuum cleaner base station to open the dustbin discharge cover of the vacuum cleaner.

[0018] However, in the case of the vacuum cleaner base station, there are the following limitations: in order to press the connecting rod, additional motors, gears and sensors are required, which increases the overall number of consumable parts and the power consumption required to operate it.

[0019] In addition, there is the following limitation: the total time required for dust collection will increase because it takes time to operate and control the motor. Summary of the Invention

[0020] The problem that the invention aims to solve

[0021] The present invention is proposed to improve the problems existing in the prior art vacuum cleaner base station, vacuum cleaner system and control method as described above. Its purpose is to provide a vacuum cleaner base station that can remove dust from the dustbin even without additional user operation, thereby providing convenience to the user.

[0022] In addition, the present invention aims to provide a vacuum cleaner base station that, when combined with a vacuum cleaner, can automatically control the discharge cover of the dust bin to connect or disconnect the internal space of the dust bin from the flow path of the vacuum cleaner base station.

[0023] In addition, the present invention aims to provide a vacuum cleaner base station that can open the exhaust cover even if the motor for opening the exhaust cover is omitted.

[0024] In addition, the present invention aims to provide a vacuum cleaner base station that can reduce the amount of electricity consumed during motor operation.

[0025] In addition, the present invention aims to provide a vacuum cleaner base station that can reduce the total dust collection time by simplifying the process from when the vacuum cleaner is connected until the dust collection motor starts to operate.

[0026] Technical solutions to the problem

[0027] To achieve the objectives described above, the vacuum cleaner base station of the present invention includes: a cover; a connecting portion disposed on the cover for engaging at least a portion of the dust bin of the vacuum cleaner; a cover opening unit for opening the discharge cover of the dust bin when the dust bin is engaged with the connecting portion; a dust collection portion housed inside the cover and disposed below the connecting portion for collecting dust inside the dust bin; and a dust collection motor housed inside the cover and disposed below the dust collection portion for generating suction to draw dust from inside the dust bin.

[0028] At this time, the dust bin includes: a dust bin body that stores dust inside and opens and closes the internal space through the discharge cover; and a connecting rod disposed on the dust bin body and releases the connection between the discharge cover and the dust bin body when an external force is applied.

[0029] At this time, the cover opening unit moves under the suction force generated by the dust collection motor and pressurizes the connecting rod.

[0030] At this time, the cover opening unit may include: a pressure moving body that moves under the suction of the dust collection motor; and a cover opening member that extends protruding from the pressure moving body toward the connecting rod.

[0031] At this time, the pressure moving body can be hinged to the cover, and can rotate toward the connecting rod when the suction force of the dust collection motor is applied.

[0032] Alternatively, when the suction force of the dust collection motor is applied, the pressure moving body can move linearly toward the connecting rod.

[0033] At this time, the cover opening member can be formed from the pressure moving body and can be formed to be inclined at a predetermined angle to the extension direction of the pressure moving body.

[0034] On the other hand, the cover opening unit may also include an air duct that internally accommodates the pressure moving body and forms a flow path for airflow when the dust collection motor is running.

[0035] At this time, the air duct may include: a duct body having an internal space for the pressure moving body to move; a stop protruding from the inner side of the duct body and restricting the downward movement of the pressure moving body; and a flow guide protruding from the inner side of the duct body and guiding the flow path of the air.

[0036] On the other hand, the vacuum cleaner base station of the present invention also includes a fixing unit, which fixes the dust bucket when the dust bucket is attached to the connecting part.

[0037] At this time, the fixing unit may include a fixing component. When an external force is applied, the fixing component moves toward the dust bin body and pressurizes the dust bin body.

[0038] At this time, when the dust collection motor is running, the fixing member can fix the dust bucket body under the suction of the dust collection motor, and the cover opening unit can pressurize the connecting rod.

[0039] On the other hand, the vacuum cleaner system of the present invention, which includes a vacuum cleaner and a vacuum cleaner base station, may include: a suction flow path through which air flows into the vacuum cleaner; a flow path section that guides dust in the dust bin to a dust collection motor; a bypass flow path that connects a cover opening formed on the guide surface of the dust bin to the flow path section; and a cover opening flow path for airflow to move the cover opening member.

[0040] At this time, the flow path and the bypass flow path can be formed in directions that intersect each other, and the bypass flow path and the cover opening flow path can be formed in directions that intersect each other.

[0041] In addition, the suction flow path and the bypass flow path can be formed in directions that intersect each other.

[0042] In addition, the length direction of the internal space of the dust bin can be formed along a direction that intersects at least one of the flow path, the suction flow path, and the cover opening flow path.

[0043] At this time, when the dust collection motor is running, the direction of airflow through the suction flow path or the cover opening flow path can be opposite to the direction of airflow through the flow path.

[0044] Invention Effects

[0045] As described above, the vacuum cleaner base station, vacuum cleaner system and control method according to the present invention have the effect of eliminating the inconvenience of users having to empty the dustbin every time.

[0046] In addition, when the vacuum cleaner is in use, it can connect or disconnect the internal space of the dust bin and the flow path of the vacuum cleaner base by rotating the control frame and controlling the discharge cover.

[0047] Additionally, the dust collection motor can be used to press the connecting rod of the dust bin to open the discharge cover, thus eliminating the need for a motor, gears, and sensors for opening the discharge cover.

[0048] In addition, it has the effect of reducing the power consumption used to operate the motor and sensors during the process of opening the discharge cover.

[0049] In addition, the present invention aims to provide a vacuum cleaner base station that can reduce the total dust collection time by simplifying the process from when the vacuum cleaner is connected until the dust collection motor starts to operate. Attached Figure Description

[0063] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0064] This invention can be modified and has various embodiments; therefore, specific embodiments are shown in the accompanying drawings and described in detail in the description.

Commonly used terms, such as those defined in dictionaries, may be interpreted as consistent with the meaning in the context of the relevant art and should not be interpreted in an ideal or excessive form unless expressly defined in this application.

[0067] Figure 1 The figure shows a perspective view of a vacuum cleaner system comprising a vacuum cleaner base station and a vacuum cleaner, according to an embodiment of the present invention. Figure 5 The diagram shows a schematic representation of the configuration of a vacuum cleaner system according to an embodiment of the present invention.

[0068] Reference Figure 1 and Figure 5 A vacuum cleaner system 10 according to one embodiment of this specification may include a vacuum cleaner base station 100 and a vacuum cleaner 200.

[0069] The vacuum cleaner system 10 may include a vacuum cleaner base station 100. A vacuum cleaner 200 may be integrated into the vacuum cleaner base station 100. Specifically, the body of the vacuum cleaner 200 may be integrated into the side of the vacuum cleaner base station 100. The vacuum cleaner base station 100 can remove dust from the dustbin 220 of the vacuum cleaner 200.

[0070] on the other hand, Figure 2 and Figure 3 The figure shows a vacuum cleaner in a vacuum cleaner system for illustrating an embodiment of the present invention. Figure 4 The figure shows the lower side of the dust bin of a vacuum cleaner used to illustrate an embodiment of the present invention.

[0071] First, refer to Figures 1 to 5 Explain the structure of vacuum cleaner 200.

[0072] Vacuum cleaner 200 can refer to a vacuum cleaner that is manually operated by the user. For example, vacuum cleaner 200 can refer to a handheld vacuum cleaner or a stick vacuum cleaner.

[0073] Vacuum cleaner 200 can be placed on vacuum cleaner base station 100. Vacuum cleaner 200 can be supported by vacuum cleaner base station 100. Vacuum cleaner 200 can be integrated with vacuum cleaner base station 100.

[0074] On the other hand, in one embodiment of the present invention, the orientation of the vacuum cleaner 200 can be defined based on the case where the dustbin 220 and the battery cover 230 are placed on the ground (lower side).

[0075] 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, the direction where the suction unit 212 is arranged to the right, based on the view of the suction motor 214, can be called the "right side," and the direction where it is arranged to the left, can be called the "left side." Additionally, in one embodiment of the present invention, the "upper side" and "lower side" can be defined along a direction perpendicular to the ground, based on the case where the dustbin 220 and the battery cover 230 are placed on the ground.

[0076] Vacuum cleaner 200 may include a body 210. Body 210 may include a body cover 211, a suction unit 212, a dust separation unit 213, a suction motor 214, an air exhaust cover 215, a handle 216, and an operating unit 218.

[0077] The body cover 211 can form the appearance of the vacuum cleaner 200. The body cover 211 can provide space to accommodate the suction motor 214 and the filter (not shown). The body cover 211 can be configured in a cylindrical shape.

[0078] The suction section 212 can protrude outward from the main body cover 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") for the flow of dust-containing air.

[0079] On the other hand, in this embodiment, a virtual line can be formed that runs through the interior of the cylindrical suction section 212.

[0080] The dust separation unit 213 can communicate with the suction unit 212. The dust separation unit 213 can separate the dust that is sucked into the unit through the suction unit 212. The space inside the dust separation unit 213 can communicate with the space inside the dust bin 220.

[0081] For example, the dust separation section 213 may have at least one cyclone section that can separate dust through cyclone flow. Furthermore, the space inside the dust separation section 213 may be in communication with the suction flow path. Therefore, the air and dust drawn in through the suction section 212 can flow spirally along the inner circumferential surface of the dust separation section 213. Thus, cyclone flow can be generated within the internal space of the dust separation section 213.

[0082] The dust separation section 213 is connected to the suction section 212 and is constructed using the principle of a dust collector that utilizes centrifugal force to separate the dust that is sucked into the body 210 through the suction section 212.

[0083] The dust separation unit 213 may further include a secondary cyclone to further separate dust from the air discharged from the cyclone. In this case, the secondary cyclone may be located inside the cyclone, minimizing the size of the dust separation unit. The secondary cyclone may include a plurality of cyclone bodies arranged side-by-side. The air discharged from the cyclone is divided into several streams by the plurality of cyclone bodies and passes through them.

[0084] At this time, the axis of the cyclone flow of the secondary cyclone can also extend in the vertical direction. The axis of the cyclone flow of the primary cyclone and the axis of the cyclone flow of the secondary cyclone can be coaxial in the vertical direction. This can be collectively referred to as the axis of the cyclone flow of the dust separation section 213.

[0085] The suction motor 214 can generate suction to draw in air. The suction motor 214 can be housed within the main body cover 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 can be formed that extends the rotation axis of the suction motor 214.

[0087] An air exhaust cover 215 can be configured on one axial side of the main body cover 211. A filter for filtering air can be accommodated in the air exhaust cover 215. For example, a high-efficiency particulate air (HEPA) filter can be accommodated in the air exhaust cover 215.

[0088] An air outlet can be formed in the air exhaust cover 215 to discharge the air drawn in by the suction force 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.

[0090] The handle 216 can be gripped by a user. The handle 216 can be positioned 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 body cover 211, the suction motor 214, or the cyclone section 213.

[0091] The handle 216 may include: a grip portion formed in a column shape so that a user can grip it; a first extension portion connected to one end of the grip portion in the longitudinal direction (axial direction) and extending toward the suction motor 214; and a second extension portion connected to the other end of the grip portion in the longitudinal direction (axial direction) and extending toward the dust bin 220.

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

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

[0094] The top surface of the handle 216 can form part of the appearance of the top surface of the vacuum cleaner 200. Thus, when the user holds the handle 216, it can prevent a part of the vacuum cleaner 200 from coming into contact with the user's arm.

[0095] The first extension can extend from the gripping part toward the main body cover 211 or the suction motor 214. At least a portion of the first extension can extend in a horizontal direction.

[0096] The second extension can extend from the grip towards the dust bin 220. At least a portion of the second extension can extend horizontally.

[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 start or stop commands for the vacuum cleaner 200 through the operation unit 218.

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

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

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

[0101] On the other hand, in this embodiment, a virtual dustbin through-line can be formed, which penetrates the interior (internal space) of the dustbin body 221 and extends along the length direction of the dustbin body 221 (referring to the axial direction in the cylindrical dustbin body 221).

[0102] The extension line of the axis in the length direction of the dust bin 220 can be formed in a direction that intersects with the suction flow path.

[0103] A portion of the lower side (bottom) of the dustbin body 221 may be open. Additionally, a bottom extension 221a may be formed on the lower side (bottom) of the dustbin body 221. The bottom extension 221a may be configured to block a portion of the lower side of the dustbin body 221.

[0104] The dust bin 220 may include a discharge cover 222. The discharge cover 222 may be disposed on the lower side of the dust bin 220.

[0105] The discharge cover 222 can be configured to open and close one end of the dust bin body 221 along its length. Specifically, the discharge cover 222 can selectively open and close the lower part of the downward-facing opening of the dust bin 220.

[0106] The discharge cover 222 may include a cover body 222a and a hinge portion 222b. The cover body 222a may be formed to seal a portion of the lower side of the dustbin body 221. The cover body 222a may rotate downward about the hinge portion 222b. The hinge portion 222b may be disposed adjacent to the battery cover 230. A torsion spring 222d may be provided in the hinge portion 222b. Therefore, when the discharge cover 222 is separated from the dustbin body 221, under the action of the spring force of the torsion spring 222d, the cover body 222a may be supported in the dustbin body 221 in a state where it can rotate more than a predetermined angle about the hinge portion 222b as an axis.

[0107] The discharge cover 222 can be engaged with the dust bin 220 via a hook. Conversely, the discharge cover 222 can be separated from the dust bin 220 via a connecting rod 222c. The connecting rod 222c can be positioned at the front of the dust bin. Specifically, the connecting rod 222c can be positioned on the outer front side of the dust 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 engagement between the cover body 222a and the dust bin body 221.

[0108] With the discharge cover 222 closed, the lower side of the dust bin 220 can be sealed by the discharge cover 222 and the bottom extension 221a.

[0109] Dust bin 220 may include dust bin compression rod 223 (see reference) Figure 3 The dustbin compression rod 223 can be disposed outside the dustbin 220 or the dust separation section 213. The dustbin compression rod 223 is movably disposed outside the dustbin 220 or the dust separation section 213. The dustbin compression rod 223 can be connected to a compression member (not shown). When the dustbin compression rod 223 moves downward by an external force, the compression member (not shown) can also move downward together. This provides convenience for the user. The compression member (not shown) and the dustbin compression rod 223 can be returned to their original positions by an elastic member (not shown).

[0110] A compressor (not shown) can be disposed inside the dustbin body 221. The compressor can move within the internal space of the dustbin body 221. Specifically, the compressor can move up and down within the dustbin body 221. This allows the compressor to compress the dust within the dustbin body 221 downwards. Furthermore, when the discharge cap 222 is separated from the dustbin body 221 and the lower part of the dustbin 220 is open, the compressor moves from the upper part of the dustbin 220 downwards, thereby removing any remaining dust or other foreign matter from the dustbin 220. This improves the suction power of the vacuum cleaner by preventing residual dust from remaining in the dustbin 220. Furthermore, by preventing residual dust from remaining in the dustbin 220, odors caused by residue can be eliminated.

[0111] The 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 configured below the handle 216.

[0112] 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 230.

[0113] Vacuum cleaner 200 may include battery 240.

[0114] For example, battery 240 can be detachably attached to vacuum cleaner 200. Battery 240 can also be detachably attached to battery housing 230. As an example, battery 240 can be inserted into the interior of battery housing 230 from below.

[0115] In contrast, the battery 240 can be integrally installed inside the battery cover 230. In this case, the bottom surface of the battery 240 is not exposed to the outside.

[0116] Battery 240 can power the suction motor 214 of vacuum cleaner 200. Battery 240 can be located at the lower part of handle 216. Battery 240 can be located at the rear of dustbin 220.

[0117] According to the embodiment, when the battery 240 is attached to the battery cover 230, the bottom surface of the battery 240 can be exposed to the outside. When the vacuum cleaner 200 is placed on the floor, the battery 240 can be placed on the floor, so the battery 240 can be directly detached from the battery cover 230. In addition, since the bottom surface of the battery 240 is exposed to the outside and in direct contact with the outside air, the cooling performance of the battery 240 can be improved.

[0118] On the other hand, with the battery 240 and the battery cover 230 fixed together, the structure for attaching and detaching the battery 240 and the battery cover 230 can be reduced, thus reducing the overall size of the vacuum cleaner 200 and achieving weight reduction.

[0119] Vacuum cleaner 200 may include an extension tube 250. The extension tube 250 may communicate with cleaning module 260. The extension tube 250 may communicate with main body 210. The extension tube 250 may communicate with suction section 212 of main body 210. The extension tube 250 may be formed in a cylindrical shape.

[0120] The main body 210 can be connected to the extension tube 250. The main body 210 can also be connected to the cleaning module 260 via the extension tube 250. The main body 210 generates suction through the suction motor 214, which can provide suction to the cleaning module 260 via the extension tube 250. External dust can flow into the main body 210 through the cleaning module 260 and the extension tube 250.

[0121] Vacuum cleaner 200 may include a cleaning module 260. The cleaning module 260 may be connected to an extension tube 250. Therefore, outside air can flow into the body 210 of vacuum cleaner 200 through the cleaning module 260 and the extension tube 250 under the suction generated by the body 210 of vacuum cleaner 200.

[0122] Dust in the dustbin 220 of the vacuum cleaner 200 can be 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 emptying the dustbin each time. Additionally, it prevents dust from scattering when emptying the dustbin.

[0123] The vacuum cleaner 200 can be attached to the side of the housing 110. Specifically, the body 210 of the vacuum cleaner 200 can rest on the connecting part 120. More specifically, the dustbin 220 and battery housing 230 of the vacuum cleaner 200 can be configured to face the connecting surface 121, the outer peripheral surface of the dustbin body 221 can be attached to the dustbin 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 dustbin 220 can be arranged in a direction parallel to the ground, and the extension tube 250 can be arranged in a direction perpendicular to the ground.

[0124] Reference Figure 1 and Figure 5 This describes the vacuum cleaner base station 100 of the present invention.

[0125] A vacuum cleaner 200 can be configured on the vacuum cleaner base station 100. The vacuum cleaner 200 can be attached to the side of the vacuum cleaner base station 100. Specifically, the body of the vacuum cleaner 200 can be attached to the side of the vacuum cleaner base station 100. The vacuum cleaner base station 100 can remove dust from the dustbin 220 of the vacuum cleaner 200.

[0126] The vacuum cleaner base station 100 may include a cover 110. The cover 110 may form the appearance of the vacuum cleaner base station 100. Specifically, the cover 110 may be formed into a column shape including at least one outer wall surface. As an example, the cover 110 may be formed into a shape similar to a quadrangular prism.

[0127] The cover 110 can be formed with a space that can accommodate a dust collection section 170 for storing dust inside and a dust suction module 190 that generates a flow force to collect dust into the dust collection section 170.

[0128] The cover 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 parallel to the ground, or it can be positioned at a predetermined angle to the ground. With this configuration, it has the advantage of being able to stably support the dust collection motor 191 and balance the overall weight when combined with the vacuum cleaner 200.

[0131] On the other hand, according to an embodiment, the bottom surface 111 may also include a bottom support portion, which 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 bottom support portion may be a plate shape extending from the bottom surface 111, or it may be formed by at least one frame protruding from the bottom surface 111 along the ground direction.

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

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

[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, "front side" can refer to the surface of the vacuum cleaner 200 exposed when the vacuum cleaner 200 is attached to 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, for the purpose of understanding this embodiment, the direction is defined as follows. In this embodiment, the direction can be defined when the vacuum cleaner 200 is placed on the vacuum cleaner base station 100.

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

[0137] From another perspective, the direction in which the suction motor 214 of the vacuum cleaner 200 is positioned when the vacuum cleaner 200 is placed on the vacuum cleaner base station 100 can be referred to as the front. Furthermore, the opposite direction in which the suction motor 214 is positioned in the vacuum cleaner base station 100 can be referred to as the rear.

[0138] Furthermore, the surface facing the front, with reference to the internal space of the cover 110, can be referred to as the back surface of the vacuum cleaner base station 100. Therefore, the back surface can refer to the direction in which the second outer wall surface 112b is formed.

[0139] Furthermore, the left side of the front view when viewed with reference to the internal space of the cover 110 can be called the left side, and the right side can be called 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.

[0140] The first outer wall surface 112a can be formed as a planar shape, or it can be formed as a curved surface as a whole, or it can be formed by including a curved surface in a part.

[0141] The first outer wall surface 112a may have an appearance corresponding to the shape of the vacuum cleaner 200. Specifically, a connecting portion 120 may be provided on the first outer wall surface 112a. With this configuration, the vacuum cleaner 200 can be attached to and supported by the vacuum cleaner base station 100. The specific configuration of the connecting portion 120 will be described later.

[0142] On the other hand, a structure for placing various types of cleaning modules 260 for vacuum cleaner 200 can also be added to the first outer wall surface 112a.

[0143] In this embodiment, the second outer wall surface 112b may be the surface facing the first outer wall surface 112a. That is, the second outer wall surface 112b may be disposed on the back side of the vacuum cleaner base station 100. Here, the back side may refer to the surface facing the vacuum cleaner 200 or the second vacuum cleaner 300. Therefore, the second outer wall surface 112b may form the appearance of the back side of the vacuum cleaner base station 100.

[0144] 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 configured on the left side of the base station 100, and the fourth outer wall surface 112d can be configured on the right side of the vacuum cleaner base station 100. Alternatively, the third outer wall surface 112c can be configured on the right side of the vacuum cleaner base station 100, and the fourth outer wall surface 112d can be configured on the left side of the vacuum cleaner base station 100.

[0145] The third outer wall surface 112c or the fourth outer wall surface 112d is formed in a planar shape. Of course, it can also be formed in a curved shape as a whole, and can be formed by including a curved surface in a part.

[0146] On the other hand, a structure for placing various forms of cleaning modules 260 for vacuum cleaner 200 can also be added to the third outer wall surface 112c or the fourth outer wall surface 112d.

[0147] The top surface 113 can form the upper appearance of the vacuum cleaner base station. That is, the top surface 113 can refer to the surface of the vacuum cleaner base station that is located at the uppermost side in the direction of gravity and exposed to the outside.

[0148] 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.

[0149] At this time, the top surface 113 can be configured parallel to the ground, or it can be configured to be tilted at a specified angle to the ground.

[0150] A display unit 410 may be configured on the top surface 113. As an example, the display unit 410 may display the status of the vacuum cleaner base station 100, the status of the vacuum cleaner 200, and may also display information such as the cleaning progress and a map of the cleaning area.

[0151] On the other hand, according to the embodiment, the top surface 113 can be detachably provided from the outer wall surface 112. In this case, if the top surface 113 is detached, the internal space surrounded by the outer wall surface 112 can accommodate a battery detached from the vacuum cleaner 200, and a terminal (not shown) capable of charging the detached battery can be provided.

[0152] Figure 6 The diagram shows a joint in a vacuum cleaner base station used to illustrate an embodiment of the present invention.

[0153] Reference Figure 5 and Figure 6 This section describes the connecting portion 120 of the vacuum cleaner base station 100 of the present invention.

[0154] The vacuum cleaner base station 100 may include a coupling portion 120 for coupling with the vacuum cleaner 200. Specifically, the coupling portion 120 may be disposed on the first outer wall surface 112a and may couple the body 210, dustbin 220 and battery cover 230 of the vacuum cleaner 200.

[0155] The joint 120 may include a mating surface 121. The mating surface 121 may be disposed on the side of the cover 110. As an example, the mating surface 121 may refer to a groove-shaped surface that is recessed from the first outer wall surface 112a toward the inside of the vacuum cleaner base station 100. That is, the mating surface 121 may refer to a surface that forms a step with the first outer wall surface 112a.

[0156] The vacuum cleaner 200 can be accommodated on the mating surface 121. As an example, the mating surface 121 can face the lower side of the dustbin 220 and battery cover 230 of the vacuum cleaner 200. Here, the lower side can refer to the side facing the ground when the user uses the vacuum cleaner 200 or places the vacuum cleaner 200 on the ground.

[0157] As an example, the angle formed between the mating surface 121 and the ground can be a right angle. Therefore, when the vacuum cleaner 200 is mated to the mating surface 121, the space of the vacuum cleaner base station 100 can be minimized.

[0158] As another example, the mating surface 121 can be configured to be inclined to the ground at a specified angle. Thus, when the vacuum cleaner 200 is mated to the mating surface 121, the vacuum cleaner base station 100 can be stably supported.

[0159] A dust passage 121a can be formed on the mating surface 121 to allow air from outside the cover 110 to flow into the interior. The dust passage 121a can be formed in a shape corresponding to the shape of the dust bin 220 so that dust from the dust bin 220 flows into the dust collection section 170. The dust passage 121a can be formed in a shape corresponding to the discharge cover 222 of the dust bin 220. The dust passage 121a can be formed to communicate with the first suction flow path 181 described later.

[0160] The mating portion 120 may include a dustbin guide surface 122. The dustbin guide surface 122 may be disposed on the first outer wall surface 112a. The dustbin guide surface 122 may be connected to the first outer wall surface 112a. In addition, the dustbin guide surface 122 may be connected to the mating surface 121.

[0161] The dustbin guide surface 122 can be formed into a shape corresponding to the outer side of the dustbin 220. The dustbin guide surface 122 can be combined with the front outer side of the dustbin 220.

[0162] On the other hand, a covered opening 122a can be formed on the dustbin guide surface 122, through which the cover opening member 530 (described later) can pass and press the connecting rod 222c. Additionally, a cover opening unit 500 can be provided on the lower side of the dustbin guide surface 122 in the direction of gravity. In this case, a bypass flow path 122b can be formed between the lower side of the dustbin guide surface 122 and the upper side of the air duct 550.

[0163] In other words, the bypass flow path 122b can refer to the space formed between the outer side of the dust bin 220 and the upper side of the air duct 550. Specifically, the bypass flow path 122b can refer to the space formed between the outer side of the dust bin 220 and the upper support surface 554 of the air duct 550, based on the state in which the dust bin 220 is attached to the dust bin guide surface 122.

[0164] Furthermore, the bypass flow path 122b can be connected to the first flow path 181 through the bypass hole 122c. That is, the cover opening hole 122a, the bypass hole 122c, and the first flow path 181 can be connected through the bypass flow path 122b (see reference). Figure 9 At this point, the bypass flow path can be formed in a direction that intersects with the direction forming the suction flow path.

[0165] With this configuration, it has the advantage that when the dust collection motor 191 is running, it can suck up the dust remaining in the dust collection bin 220 and the dust collection bin guide surface 122 through the bypass flow path, with the dust bin 220 connected to the joint 120.

[0166] Furthermore, in this invention, when the dust collection motor 191 is running while the dust bin 220 is engaged with the joint 120, the suction force of the dust collection motor 191 can be transmitted through the bypass flow path, thereby enabling the pressure moving body 510 described later to operate.

[0167] The connecting portion 120 may include a guide protrusion 123. The guide protrusion 123 may be disposed on the connecting surface 121. The guide protrusion 123 may protrude from the connecting surface 121 toward the front of the vacuum cleaner base station 100. Two guide protrusions 123 may be disposed separately from each other. The distance between the two separate guide protrusions 123 may correspond to the width of the battery cover 230 of the vacuum cleaner 200. Thus, convenience can be provided when the vacuum cleaner 200 is connected to the connecting surface 121.

[0168] The joint 120 may include sidewalls 124. Sidewalls 124 refer to walls disposed on both sides of the joint surface 121, and can be perpendicularly connected to the joint surface 121. Sidewalls 124 can be connected to the first outer wall surface 112a. Additionally, sidewalls 124 can form a surface that connects to the dustbin guide surface 122. Thus, the vacuum cleaner 200 can be stably accommodated.

[0169] The coupling portion 120 may include a coupling sensor 125. The coupling sensor 125 can sense whether the vacuum cleaner 200 is coupled to the coupling portion 120.

[0170] The engagement sensor 125 may also include a contact sensor. As an example, the engagement sensor 125 may include a microswitch. In this case, the engagement sensor 125 may be configured on the guide protrusions 123. Therefore, if the battery cover 230 or the battery 240 of the vacuum cleaner 200 is engaged between a pair of guide protrusions 123, it will come into contact with the engagement sensor 125, which can detect that the vacuum cleaner 200 has been engaged.

[0171] 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 side wall 124. Therefore, if the dustbin 220 or the body 210 of the vacuum cleaner 200 reaches the mating surface 121 via the side wall 124, the sensor 125 can sense the presence of the dustbin 220 or the body 210.

[0172] The sensor 125 can be positioned opposite the dustbin 220 or the battery cover 230 of the vacuum cleaner 200.

[0173] The sensor 125 can be used to determine whether power is being applied to the battery 240 of the vacuum cleaner 200 and whether the device is connected to the vacuum cleaner 200.

[0174] 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 bin guide surface 122. The suction portion 212 may be connected 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.

[0175] The joint 120 may also include a fixing member access hole 127. The fixing member access hole 127 may be formed in the form of an elongated hole along the side wall 124 so as to allow the fixing member 131 to enter and exit.

[0176] With this configuration, when the user attaches the vacuum cleaner 200 to the attachment portion 120 of the vacuum cleaner base station 100, the body 210 of the vacuum cleaner 200 can be stably positioned at the attachment portion 120 via the dustbin guide surface 122, the guide protrusion 123, and the suction part guide surface 126. This provides convenience for attaching the dustbin 220 and battery cover 230 of the vacuum cleaner 200 to the attachment surface 121.

[0177] Reference Figure 5 , Figure 7 as well as Figure 18 This describes the fixing unit 130 of the present invention.

[0178] The vacuum cleaner base station 100 of the present invention may include a fixing unit 130. The fixing unit 130 may be disposed on a side wall 124. The fixing unit 130 may fix the vacuum cleaner 200 to the dustbin guide surface 122. Specifically, the fixing unit 130 may fix the dustbin 220 of the vacuum cleaner 200 to the dustbin guide surface 122.

[0179] The fixing unit 130 may include a fixing member 131 for fixing the dust bin 220 of the vacuum cleaner 200 and the battery cover 230.

[0180] The fixing member 131 can be disposed on the side wall 124 of the joint 120, and can be reciprocally disposed on the side wall 124 to fix the dust bin 220. Specifically, the fixing member 131 can be accommodated inside the fixing member inlet hole 127.

[0181] The fixing members 131 can be respectively disposed on both sides of the joint 120. As an example, two fixing members 131 can be disposed symmetrically in pairs with the joint surface 121 as the center.

[0182] When an external force is applied, the fixing member 131 can move toward the dust bin 220 and fix the dust bin. In addition, when the external force is released, the fixing member 131 fixing the dust bin 220 can move away from the dust bin 220.

[0183] As an example, the fixed member 131 can be moved by the power of a motor. That is, the fixed member 131 can receive power and move by at least one motor and a linkage connected to the motor.

[0184] As another example, the fixing member 131 can move under the suction of the dust collection motor 191. That is, the fixing member 131 can receive suction and move through a flow path such as a hose.

[0185] On the other hand, the fixing unit 130 may also include a fixing seal 136. The fixing seal 136 may be disposed on the dustbin guide surface 122 to provide an airtight seal for the dustbin 220 when the vacuum cleaner 200 is engaged. With this configuration, when the dustbin 220 of the vacuum cleaner 200 is engaged, the weight of the vacuum cleaner 200 can pressurize the fixing seal 136, thereby sealing the dustbin 220 and the dustbin guide surface 122.

[0186] Therefore, the suction power of the vacuum cleaner can be improved by preventing residual dust from remaining in the dustbin. Furthermore, by preventing residual dust from remaining in the dustbin, odors caused by residue can be eliminated.

[0187] Reference Figure 5 and Figure 8 This describes the dustbin lid control unit 140 of the present invention.

[0188] The vacuum cleaner base station 100 of the present invention may include a dustbin lid control unit 140. The dustbin lid control unit 140 may be configured to open and close the dust passage 121a.

[0189] The dustbin lid control unit 140 may include a lid control frame 141, a lid control motor 142, and a connecting rod 143.

[0190] The cover control frame 141 can be hinged to the cover 110 and can open and close the dust vent 121a. The cover control frame 141 may include a frame body 141a.

[0191] The frame body 141a can be formed into a shape that can block the dust passage 121a. As an example, the frame body 141a can be formed into a shape similar to a circular plate. As another example, the frame body 141a can be formed into a quadrilateral plate shape.

[0192] Based on the state where the dust passage 121a is blocked by the frame body 141a, a hinge part 141b can be arranged on the upper side of the frame body 141a, and a connecting rod joint part 141c can be arranged on the lower side of the frame body 141a.

[0193] The hinge portion 141b can be disposed on the upper end of the frame body 141a and can be hinged to the cover 110.

[0194] The connecting rod joint 141c can be disposed on the lower side of the frame body 141a, and the connecting rod 143 can be rotatably connected thereto.

[0195] With this configuration, when the cover control frame 141 blocks at least a portion of the dust passage 121a, when the connecting rod 143 pulls the frame body 141a, the frame body 141a can rotate about the hinge portion 141b towards the inside of the vacuum cleaner base station 100, thereby opening the dust passage 121a. On the other hand, when the dust passage 121a is open, when the connecting rod 143 pushes the frame body 141a, the frame body 141a can rotate about the hinge portion 141b towards the outside of the vacuum cleaner base station 100, and can block at least a portion of the dust passage 121a.

[0196] On the other hand, when the vacuum cleaner 200 is attached to the vacuum cleaner base station 100 and the discharge cover 222 is separated from the dustbin body 210, the cover control frame 141 can contact the discharge cover 222. Furthermore, as the cover control frame 141 rotates, the discharge cover 222 can rotate in conjunction with the cover control frame 141.

[0197] The cover control motor 142 can provide the power to rotate the cover control frame 141. Specifically, the cover control motor 142 can rotate the connecting rod 143 in either the forward or reverse direction.

[0198] Here, "forward" can refer to the direction in which the connecting rod 143 pulls the cover control frame 141. Therefore, when the connecting rod 143 rotates in the forward direction, the discharge cover 222 can be opened. Furthermore, when the connecting rod 143 rotates in the forward direction, the internal space of the dust bin 220 can communicate with the flow path section 180.

[0199] Alternatively, "reverse" can refer to the direction in which the connecting rod 143 pushes the cover control frame 141. Therefore, when the connecting rod 143 rotates in the reverse direction, the discharge cover 222 can be closed. Furthermore, when the connecting rod 143 rotates in the reverse direction, the communication between the internal space of the dust bin 220 and the flow path 180 can be severed. "Forward" can be the opposite direction to "reverse".

[0200] Link 143 can connect cover control frame 141 and cover control motor 142, and can open and close cover control frame 141 by using the power generated in cover control motor 142.

[0201] As an example, link 143 may include a first link 1431 and a second link 1432. One end of the first link 1431 may be engaged with a cover control motor 142. The first link 1431 can be rotated by the power of the cover control motor 142. The other end of the first link 1431 may be rotatably engaged with the second link 1432. The first link 1431 can transmit the force transmitted from the cover control motor 142 to the second link 1432. One end of the second link 1432 may be engaged with the first link 1431. The other end of the second link 1432 may be engaged with a cover control frame 141. The second link 1432 can open and close the discharge cover 222 by pushing and pulling the cover control frame 141.

[0202] The first link 1431 may include a first link body 1431a, a motor coupling portion 1431b, a sensing protrusion 1431c, and a key protrusion 1431d.

[0203] The first link body 1431a can transmit power from the cover control motor 142 to the second link 1432. For example, the first link body 1431a can be formed in a frame shape, and a motor coupling portion 1431b can be arranged on one side in the length direction, and a key protrusion 1431d can be formed on the other side in the length direction. Therefore, the first link body 1431a can be a rotating body that rotates about the motor coupling portion 1431b as an axis.

[0204] The motor coupling 1431b can be configured on one side of the first connecting rod body 1431a along its length.

[0205] The motor coupling 1431b can be coupled to the cover control motor 142. For example, the motor coupling 1431b can be directly coupled to the shaft of the cover control motor 142, or it can be coupled through at least one gear (not shown). In this case, the motor coupling 1431b can become the rotation shaft of the first link 1431.

[0206] On the other hand, at least a portion of the covered control motor 142 can be accommodated in the motor coupling 1431b. For example, the motor coupling 1431b can be formed as a cylindrical shape with one side sealed to accommodate the shaft or gear of the covered control motor 142. With this configuration, the motor coupling 1431b can rotate when the covered control motor 142 is running.

[0207] On the other hand, the sensing protrusion 1431c can be formed protruding from the outer peripheral surface of the motor coupling portion 1431b. Two sensing protrusions 1431c can be formed along the outer peripheral surface of the motor coupling portion 1431b at a predetermined interval. That is, among the sensing protrusions 1431c, the first sensing protrusion 1431ca and the second sensing protrusion 1431cb can be formed protruding along the outer peripheral surface of the motor coupling portion 1431b at a predetermined interval. Therefore, with the rotation center of the motor coupling portion 1431b as a reference, the diameter of the portion containing the sensing protrusion 1431c can be larger than the diameter to the outer peripheral surface of the motor coupling portion 1431b. With this configuration, the motor coupling portion 1431b and the sensing protrusion 1431c can function as a cam.

[0208] On the other hand, the sensing protrusion 1431c can rotate integrally with the motor coupling 1431b. That is, the sensing protrusion 1431c can rotate together with the rotation of the first connecting rod 1431.

[0209] As the first link 1431 rotates, the sensing protrusion 1431c can come into contact with the cover control sensor 144. With this configuration, the sensing protrusion 1431c can sense the rotational position (angle) of the first link 1431 by contacting the cover control sensor 144.

[0210] The first sensing protrusion 1431ca can be configured to sense the position of the cover control frame 141 when the discharge cover 222 is closed. Furthermore, the second sensing protrusion 1431cb can be configured to sense the position of the cover control frame 141 when the discharge cover 222 is open.

[0211] On the other hand, the rotation of the connecting rod 143 can be limited by the connecting rod stops 115a and 115b. That is, the first connecting rod 1431 can be locked in place by the first connecting rod stop 115a and the second connecting rod stop 115b, thereby limiting its rotation. In other words, when the first connecting rod 1431 contacts the first connecting rod stop 115a or the second connecting rod stop 115b, its rotation can be stopped.

[0212] Furthermore, when the first link 1431 is engaged with the first link stop 115a, the first sensing protrusion 1431ca can contact the cover control sensor 144. Additionally, when the first link 1431 is engaged with the second link stop 115b, the second sensing protrusion 1431cb can contact the cover control sensor 144.

[0213] With this configuration, when the first link 1431 rotates to a preset position, the first link 1431 can physically contact the link stop 115, thereby restricting its rotation. At the same time, the control unit 400 can stop the operation of the cover control motor 142 by sensing the position of the first link 1431, so that the first link 1431 rotates to the correct position.

[0214] On the other hand, the key protrusion 1431d can engage with the keyhole 1432b formed in the second link 1432. The key protrusion 1431d can also be formed on the other side of the length direction of the first link body 1431a.

[0215] The key protrusion 1431d may be formed by protruding from the surface of the first link body 1431a facing the second link 1432. In this case, the key protrusion 1431d may be formed to be keyed to the second link 1432. For example, the key protrusion 1431d may be formed in a cylindrical shape, and at least one protrusion may be formed from the outer peripheral surface to the radially outward.

[0216] The second link 1432 may include a second link body 1432a, a keyhole 1432b, and a frame connection part 1432c.

[0217] The second link body 1432a can transmit the power from the first link 1431 to the cover control frame 141. For example, the second link body 1432a can be formed in a frame shape, and a keyhole 1432b can be formed on one side in the length direction, and a frame connecting portion 1432c can be arranged on the other side in the length direction. Therefore, the second link body 1432a can be a rotating body that rotates about the key protrusion 1431d.

[0218] A keyhole 1432b may be formed on one side of the second link body 1432a. The keyhole 1432b may be shaped to correspond to the key protrusion 1431d. For example, the keyhole 1432b may be shaped as a circular hole, and a quadrilateral hole may be connected to it on the radially outer side. With this configuration, the key protrusion 1431d and the keyhole 1432b are matched in shape and can be inserted and engaged, thereby preventing them from disengaging from each other when the first link 1431 and the second link 1432 are rotating.

[0219] Therefore, according to the present invention, the key protrusion 1431d of the first link 1431 can be keyed to the key hole 1432b of the second link 1432, thereby making it easy to assemble or replace the first link 1431 and the second link 1432, while preventing the first link 1431 and the second link 1432 from disengaging during operation.

[0220] The frame connection 1432c can be configured on the other side of the length direction of the second link body 1432a.

[0221] The frame connection 1432c can be combined with the cover control frame 141. The frame connection 1432c can be hinged to the link connection 141c. In this case, the hinge that combines the frame connection 1432c with the cover control frame 141 can become the rotation axis of the second link 1432.

[0222] On the other hand, in this invention, the maximum length of the first link 1431 can be shorter than the maximum length of the second link 1432. Furthermore, the maximum length of the first link 1431 can be shorter than the length from the hinge portion 141b of the cover control frame 141 to the link connection portion 141c. Also, the length from the hinge portion 141b of the cover control frame 141 to the link connection portion 141c can be shorter than the rotation radius of the second link 1432 (more specifically, the length from the rotation center of the keyhole 1432b of the second link 1432 to the frame connection portion 1432c).

[0223] With this configuration, when the first link 1431 rotates about the motor joint 1431b as the rotation axis and the cover control frame 141 rotates about the hinge 141b as the rotation axis, the second link 1431 connecting the first link 1431 and the cover control frame 141 can apply a large force during the closing of the discharge cover 222.

[0224] That is, during the process of closing the discharge cover 222, as the first link 1431 rotates, the rotation angle of the cover control frame 141 gradually increases. Therefore, due to the increase in the rotation speed of the cover control frame 141, the discharge cover 222 can be closed forcefully.

[0225] As a result, the force Fc exerted by the cover control frame 141 to close the discharge cover 222 can be increased to be greater than the force transmitted from the first link 1431 to the second link 1432. Therefore, it has the effect of generating sufficient force to close the discharge cover 222 even when the cover control motor 142 applies a small output torque to the first link 1431.

[0226] Therefore, according to the present invention, since the discharge cover 222 can be closed by using a motor with a smaller output, it has the effect of reducing the size of the motor and reducing volume and weight, and noise can also be reduced at the same time.

[0227] On the other hand, the dustbin lid control unit 140 may also include a lid control sensor 144. The lid control sensor 144 may be disposed inside the cover 110 and may sense whether the lid control frame 141 is in an open state.

[0228] For example, the cover control sensor 144 can be configured at a position that can contact the sensing protrusion 1431c. Furthermore, the cover control sensor 144 can be configured at a position that does not contact the outer peripheral surface of the motor coupling portion 1431b. Therefore, when the first link 1431 rotates and contacts the sensing protrusion 1431c, the cover control sensor 144 can sense the sensing protrusion 1431c.

[0229] Therefore, when the first link 1431 rotates, causing the first sensing protrusion 1431ca to contact the cover control sensor 144, the cover control sensor 144 can sense that the cover control frame 141 closes the dust bin 220. Additionally, when the first link 1431 rotates, causing the second sensing protrusion 1431cb to contact the cover control sensor 144, the cover control sensor 144 can sense that the cover control frame 141 opens the discharge cover 222.

[0230] The cover control sensor 144 may also include a contact sensor. As an example, the cover control sensor 144 may include a micro switch.

[0231] When the exhaust cover 222 of the vacuum cleaner 200 is opened, the cover control frame 141 can also be opened. Furthermore, when the cover control frame 141 is closed, the exhaust cover 222 of the vacuum cleaner 200 can be closed in conjunction with it.

[0232] When the dust in the dustbin 220 of the vacuum cleaner 200 has been removed, the cover control motor 142 can rotate the cover control frame 141, thereby engaging the discharge cover 222 with the dustbin body 221. Specifically, the cover control motor 142 can rotate the first link 143, thereby rotating the cover control frame 141, and the rotating cover control frame 141 can push the discharge cover 222 toward the dustbin body 221.

[0233] Reference Figure 5 , Figures 9 to 15 This describes the cover opening unit 500 of the present invention.

[0234] The vacuum cleaner base station 100 of the present invention may include a cover opening unit 500. The cover opening unit 500 may be disposed on the lower side of the joint portion 120 and opens the exhaust cover 222 of the vacuum cleaner 200.

[0235] The cover opening unit 500 may include a pressure moving body 510, a hinge portion 520, a cover opening member 530, a head 540, and an air duct 550.

[0236] At this time, the pressure moving body 510, hinge part 520, cover opening member 530 and head 540 can be rotatably arranged inside the air duct 550. With the operation of the dust collection motor 191, the cover opening member 530 can reciprocate inside and outside the air duct 550.

[0237] The pressure-moving body 510 can move under the suction of the dust collection motor 191. The pressure-moving body 510 can be hinged to the air duct 550 and rotate with the air pressure.

[0238] Therefore, the pressure moving body 510 can be formed to block at least a portion of the internal space of the air duct 550. For example, the width of the pressure moving body 510 in the left-right direction can be smaller than the internal width of the air duct 550 in the left-right direction, and can be formed to have a width very close to it. In addition, the length of the pressure moving body 510 in the front-back direction can be smaller than the maximum distance from the rotation center of the pressure moving body 510 to the flow guide 553 described later, and can be formed to have a length very close to it.

[0239] With this configuration, the pressure moving body 510 can move due to the air flow and pressure difference inside the air duct 550.

[0240] On the other hand, the pressure moving body 510 can be formed into a plate shape with a specified thickness.

[0241] At this time, the pressure moving body 510 can be formed with a bent portion 511 that bends at a predetermined angle. For example, based on the state where the dust collection motor 191 is not running, in the pressure moving body 510, the front side where the cover opening member 530 is located is bent downwards more than the rear side connected to the hinge portion 520. With this configuration, when the dust collection motor 191 is running, the stroke length of the cover opening member 530 can be increased, and the force applied to the connecting rod 222c can be increased.

[0242] On the other hand, at least one groove 512 can be formed on the lower surface of the pressure moving body 510. With this configuration, the overall weight of the pressure moving body 510 can be reduced, thus having the advantage of making it easier to move with the operation of the dust collection motor 191. In addition, since the lower surface area of ​​the pressure moving body 510 is widened, the operating performance of the pressure moving body 510 is improved with the flow of air.

[0243] On the other hand, such as Figure 13 As shown, a seal 513 may also be provided on the upper side of the pressure moving body 510.

[0244] The seal 513 can be located between the upper side of the airtight pressure moving body 510 and the upper support surface 554 of the air duct 550. In this case, the seal 513 can be configured to surround the upper side of the pressure moving body 510.

[0245] On the other hand, a wide variety of materials that can provide airtightness can be used for the seal 513.

[0246] With this configuration, when the suction force of the dust collection motor 191 is applied, the pressure moving body 510 can respond more sensitively, and the dust collection performance can be improved through the airtight air duct 550 and the flow path 180 when the connecting rod 222c is pressed.

[0247] In addition, when the seal 513 is formed of an elastic material, the upper side of the pressure moving body 510 can absorb the impact when it comes into contact with the air duct 550, thereby preventing the pressure moving body 510 or the air duct 550 from being damaged.

[0248] The hinge portion 520 can be configured on one side of the pressure moving body 510 along its length and can be combined with the air duct 550 to provide the rotation center of the pressure moving body 510.

[0249] For example, a hinge portion 520 is formed at the rear end of the pressure moving body 510, at least a portion of which is formed in a curved shape and rotatably engaged. In this case, the position where the hinge portion 520 is engaged can be engaged with the air duct 550, or it can be engaged with a part of the cover 110 connected to the air duct 550.

[0250] At this time, the hinge portion 520 can provide a rotation axis formed in the left-right direction of the vacuum cleaner base station 100 to the pressure moving body 510. Therefore, the pressure moving body 510 can rotate up and down around the hinge portion 520.

[0251] The cover opening member 530 extends protruding from the pressure moving body 510 toward the connecting rod 222c of the dust bin 220 and is configured to press the connecting rod 222c as the pressure moving body 510 rotates.

[0252] The cover opening member 530 can be formed by protruding from the upper side of the pressure moving body 510, and can be formed by tilting at a predetermined angle to the extending direction of the pressure moving body 510. At this time, the cover opening member 530 can be formed by protruding circumferentially from the upper side of the pressure moving body 510 with the rotation center of the hinge portion 520 as the origin. With this configuration, when the pressure moving body 510 rotates, the possibility of the cover opening member 530 colliding with other structures can be minimized, and the connecting rod 222c can be pressed with sufficient movement.

[0253] The head 540 can be configured on the other side of the pressure moving body 510 along its length and can come into contact with the air duct 550 during the operation of the pressure moving body 510.

[0254] For example, a head 540 may be formed on the front end of the pressure moving body 510 and may be formed to be thicker than the pressure moving body 510, and at least a portion of its front end may be formed to be curved.

[0255] With this configuration, as the pressure moving body 510 rotates, even if the stop 552 collides with the upper side of the air duct 550, it can absorb the impact, thereby achieving the effect of making the flow path 180 and the air duct 550 airtight.

[0256] The air duct 550 is configured to have a flow path formed inside it to supply airflow when the dust collection motor 191 is running, and to house a pressure moving body 510 inside it, allowing the pressure moving body 510 to move along the flow path.

[0257] The air duct 550 includes a duct body 551, a stop 552, a flow guide 553, an upper support surface 554, and a vent 555.

[0258] The pipe body 551 can be disposed inside the cover 110 and can be disposed on the lower side of the joint 120 in the direction of gravity.

[0259] A space for the pressure moving body 510 to move can be provided inside the pipe body 551. For example, the pipe body 551 can be formed into a box shape similar to a hexahedron. In this case, the width in the left-right direction and the length in the front-back direction of the internal space of the pipe body 551 can be greater than the width in the left-right direction and the length in the front-back direction of the pressure moving body 510.

[0260] An airflow space can be provided inside the duct body 551. The upper end of the duct body 551 can be connected to the dust bin guide surface 122, and a covered opening 122a can be formed at the upper end 551a of the duct body 551 and the dust bin guide surface 122. In addition, a vent 555 can be formed at the lower part of the duct body 551. Therefore, when the dust collection motor 191 is running, air can flow in through the vent 555, flow inside the duct body 551, and then flow through the covered opening 122a into the bypass flow path 122b, and then flow through the flow path section 180 to the dust collection motor 191.

[0261] That is, a covered open flow path 556 can be formed inside the pipe body 551. When the dust collection motor 191 is running, air can flow in the pipe body 551, so that the pressure moving body 510 installed inside can move.

[0262] The stop 552 can be formed by protruding from the inner side of the pipe body 551 and can restrict the downward movement of the pressure moving body 510. For example, the stop 552 can be formed by bending the lower end of the flow guide 553 that protrudes from the inner side of the pipe body 551 at an angle to the rear.

[0263] Therefore, when the pressure moving body 510 rotates downwards due to gravity, it can come into contact with the stop 552, thereby limiting the downward rotation. At this time, an airtight seal can be formed between the stop 552 and the pressure moving body 510.

[0264] The flow guide 553 can be formed by protruding from the inner side of the pipe body 551 and can guide the flow path of air. Specifically, the flow guide 553 can be formed by protruding from the inner side of the upper side of the pipe body 551 downward.

[0265] At this time, the flow guide 553 can be formed into a shape that draws an arc around the rotation center of the pressure moving body 510. With this configuration, when the pressure moving body 510 rotates, the space between the front end of the pressure moving body 510 and the flow guide 553 can be minimized, and when the dust collection motor 191 is running, the response performance of the pressure moving body 510 can be maximized.

[0266] On the other hand, the length of the pipe body 551 in the front-to-back direction is greater than the shortest distance from the rear end of the pipe body 551 to the stop 552. Therefore, when the dust collection motor 191 operates, the air flowing inside the pipe body 551 increases in velocity as it passes the stop 552, thus providing the advantage that the pressure moving body 510 can be rotated even with a relatively small output dust collection motor 191. At the same time, since the groove 512 of the pressure moving body 510 is formed to be the same area as the area from the rear end of the pipe body 551 to the stop 552, the increased air velocity can push the wider surface area of ​​the pressure moving body 510 upwards, thereby maximizing the responsiveness of the pressure moving body 510.

[0267] The upper support surface 554 can refer to the rear upper side of the pipe body 551. In this embodiment, the front upper side of the pipe body 551 can be the dust bin guide surface 122. The upper support surface 554 can be formed by tilting downward from the dust bin guide surface 122 at a predetermined angle. That is, the upper support surface 554 can be a surface formed by tilting relative to the ground at a predetermined angle. At this time, the tilt angle of the upper support surface can be the same as the tilt of the bend 511 from the pressure moving body 510. With this configuration, when the pressure moving body 510 rotates upward, the upper side of the pressure moving body 510 can be in close contact with the upper support surface 554, thereby increasing the airtightness.

[0268] A vent 555 may be formed on the lower side of the pipe body 551 to allow external air to flow in. Here, external air may refer to air other than the air flowing through the flow path 180.

[0269] For example, the vent 555 can be formed as a plurality of circular holes with a specified diameter. This is so that, compared to forming a single hole with a relatively large diameter, the air inside the pipe body 551 can flow uniformly, and the impact on the airflow can be minimized even if any hole is blocked by a foreign object.

[0270] On the other hand, the cover opening flow path 556 of the present invention is formed in a direction that intersects with the bypass flow path 122b, and the bypass flow path 122b is formed in a direction that intersects with the flow path portion 180. As a result, at least a portion of the cover opening flow path 556 and the flow path portion 180 can be parallel to each other, but the flow directions are opposite.

[0271] Furthermore, the cover-open flow path 556 can be formed in a direction intersecting the extension line of the axis in the length direction of the dust bin 220. Alternatively, the cover-open flow path 556 can be formed in a direction parallel to the suction flow path.

[0272] Therefore, the direction of movement of the lid opening member 530 can intersect the extension line of the axis in the length direction of the dust bin 220, and the lid opening member 530 can move in a direction intersecting the length direction of the dust bin 220. That is, the lid opening member 530 can move from the outer side of the outer peripheral surface of the cylindrical dust bin 220 toward the radial inner side of the dust bin 220.

[0273] On the other hand, refer to Figure 14 and Figure 15 This describes the operation of the cover opening unit 500 according to an embodiment of the present invention.

[0274] When the dust collection motor 191 operates, a negative pressure is formed in the bypass hole 122c under the suction force of the dust collection motor 191. Therefore, air in the bypass flow path 122b can flow into the flow path section 180, and a negative pressure can be formed in the space formed between the pressure moving body 510 and the dust bucket guide surface 122 and the cover-open flow path 556. Figure 14 ).

[0275] Therefore, an upward pressure can be applied to the pressure moving body 510, which can rotate about the hinge portion 520. Thus, the cover opening member 530 can rotate together with the pressure moving body 510 while simultaneously applying pressure to the connecting rod 222c.

[0276] At this time, the direction in which the cover opening unit 500 pressurizes the connecting rod 222c can be a direction that intersects the length direction of the dust bin 220.

[0277] Through this process, as the connecting rod 222c rotates through the cover opening unit 500, the hook connection between the dust bin body 221 and the discharge cover 222 is released. Figure 15 At this time, a torsion spring 222d can be provided in the discharge cover 222. The discharge cover 222 can rotate more than a specified angle under the elastic force of the torsion spring 222d and be supported in the rotated position. Therefore, the discharge cover 222 can be opened and can connect the dust through hole 121a and the inside of the dust bin 220.

[0278] on the other hand, Figure 16 and Figure 17 A diagram is shown illustrating a cover opening unit in a vacuum cleaner base station for illustrating another embodiment of the present invention.

[0279] Reference Figure 16 and Figure 17 This describes another embodiment of the cover opening unit of the present invention.

[0280] The cover opening unit 1500 of this embodiment includes a pressure moving body 1510, a support part 1520, a cover opening member 1530, and an air duct 1550.

[0281] On the other hand, to avoid repeated explanations, in this embodiment, unless otherwise specifically mentioned, the structure and effects of the cover opening unit 500 of an embodiment of the present invention may be referred to.

[0282] The pressure moving body 1510 of this embodiment can be housed within the air duct 1550 and can reciprocate linearly when the dust collection motor 191 is running. For example, the pressure moving body 1510 can be formed into a cuboid shape with a specified thickness.

[0283] At this time, the size of the pressure moving body 1510 can be slightly smaller than the internal space of the air duct 1550. For example, the width in the left-right direction and the length in the front-back direction of the internal space of the air duct 1550 are greater than the width in the left-right direction and the length in the front-back direction of the pressure moving body 1510, but smaller than the shortest diagonal of the pressure moving body 1510.

[0284] With this configuration, even if air flows within the air duct 1550, the pressure moving body 1510 will not rotate and can reciprocate linearly within the air duct 1550.

[0285] Furthermore, even if there is no separate guide rail inside the air duct 1550, the pressure moving body 1510 can still move linearly.

[0286] The support portion 1520 can be formed extending upward from the rear side of the pressure moving body 1510, and can be connected to and support the cover opening member 1530.

[0287] During the upward movement of the cover opening member 1530, if the support part 1520 collides with the dust bucket guide surface 122 or with the connecting rod 222c, it can prevent the cover opening member 1530 from deforming or breaking.

[0288] The lid opening member 1530 extends upward from the pressure moving body 1510. When the suction force of the dust collection motor 191 is applied, the lid opening member 1530 can move linearly toward the connecting rod 222c.

[0289] The cover opening member 1530 includes a pressure surface 1531 and a guide surface 1532.

[0290] When the dust collection motor 191 is running, the pressure surface 1531 can press the connecting rod 222c.

[0291] The pressure surface 1531 can be formed at a specified angle relative to the ground. In this case, the angle of inclination of the pressure surface 1531 is greater than the rotation angle of the connecting rod 222c used to open the discharge cover 222.

[0292] With this configuration, when the pressure surface 1531 is fully raised, the connecting rod 222c can be rotated to the tilt level of the pressure surface 1531, thus disengaging the dust bin body 221 and the discharge cover 222.

[0293] The guide surface 1532 can guide the rise of the pressure moving body 1510. During the rise of the pressure moving body 1510, when the dust bucket guide surface 122 comes into contact with the cover opening member 1530, it can move along the guide surface 1532 and guide the cover opening member 1530 through the dust through hole 122a.

[0294] The guide surface 1532 can be formed at a predetermined angle relative to the ground. In this case, the inclination of the guide surface 1532 relative to the ground can be greater than the inclination of the pressure surface 1531 relative to the ground.

[0295] On the other hand, the uppermost end of the pressure surface 1531 and the uppermost end of the guide surface 1532 can coincide with each other. Therefore, this can be referred to as the uppermost end of the cover opening member 1530. The position of this uppermost end of the cover opening member 1530 can be configured to be closer to the front relative to the rotation axis of the connecting rod 222c. Therefore, when the cover opening member 1530 rises, the uppermost end of the cover opening member 1530 can contact the connecting rod 222c first and can be pressurized in the direction of opening the connecting rod 222c.

[0296] The air duct 1550 is configured to have a flow path formed inside it to supply airflow when the dust collection motor 191 is running, and to house a pressure moving body 1510 inside it, allowing the pressure moving body 1510 to move along the flow path.

[0297] On the other hand, refer to Figure 5 and Figure 18 This indicates that the dust collection section is 170.

[0298] The vacuum cleaner base station 100 may include a dust collection unit 170. The dust collection unit 170 may be disposed inside the cover 110. The dust collection unit 170 may be disposed on the lower side of the joint 120 in the direction of gravity.

[0299] As an example, the dust collection unit 170 can refer to a dust bag that is used by the dust collection motor 191 to collect dust sucked in from inside the dust bin 220 of the vacuum cleaner 200.

[0300] The dust collection unit 170 can be detachably attached to the cover 110.

[0301] Therefore, the dust collection unit 170 can be separated from the cover 110 and discarded, and a new dust collection unit 170 can be attached to the cover 110. That is, the dust collection unit 170 can be defined as a consumable part.

[0302] When suction is generated by the dust collection motor 191, the dust bag can increase in volume while containing dust inside.

[0303] Therefore, dust bags can be made of a material that allows air to pass through while preventing the passage of foreign objects such as dust. As an example, dust bags can be made of non-woven fabric and can be hexahedral in shape when the volume increases.

[0304] Therefore, users do not need to tie up separate dust-collecting bags, thus improving user convenience.

[0305] In contrast, dust bags may comprise rolls of plastic (not shown). This configuration prevents dust or odors trapped inside the dust bag from leaking out when the dust bag is sealed or joined. The dust bag can then be installed onto the cover 110 via a dust bag holder (not shown). The dust bag can be replaced via the dust bag holder as needed.

[0306] On the other hand, refer to Figure 5 and Figure 18 This indicates that the flow path is 180.

[0307] The vacuum cleaner base station 100 may include a flow path section 180.

[0308] The flow path 180 can connect the dustbin 220 and the dust collection section 170 of the vacuum cleaner 200. The flow path 180 can be disposed on the rear side of the mating surface 121. The flow path 180 can refer to the space between the dustbin 220 and the dust collection section 170 of the vacuum cleaner 200. The flow path 180 can be a space formed rearward from the dust through hole 121a, or a flow path formed by bending downward from the dust through hole 121a to allow the flow of dust and air.

[0309] Specifically, when the vacuum cleaner 200 is combined with the vacuum cleaner base station 100 and the dust passage 121a is open, it may include a first flow path 181 communicating with the internal space of the dust bin 220 and a second flow path 182 communicating between the first flow path 181 and the internal space of the dust collection section 170.

[0310] As an example, the first flow path 181 can be configured to be substantially parallel to the axis of the suction motor 214 or a virtual through-line through the dust bin 220. In this case, the axis of the suction motor 214 or the through-line through the dust bin 220 can pass through the first flow path 181.

[0311] At this time, the second flow path 182 can be configured to form a predetermined angle with the first flow path 181. For example, the first flow path 181 and the second flow path 182 can be configured to be at right angles. With this configuration, the overall volume of the vacuum cleaner base station 100 can be minimized.

[0312] The second flow path 182 can be formed by extending downward from the first flow path 181, and can communicate with the first flow path 181 and guide the air through the first flow path 181 to the dust collection section 170.

[0313] The second flow path 182 can be configured in a direction parallel to the axis C of the dust collection motor 191. With this configuration, the reduction in suction power of the dust collection motor 191 in the first flow path 181 and the second flow path 182 can be minimized.

[0314] Through the flow path section 180, the dust in the dust bin 220 of the vacuum cleaner 200 can move to the dust collection section 170.

[0315] On the other hand, refer to Figure 5 and Figure 18 This indicates the dust suction module 190.

[0316] The vacuum cleaner base station 100 may include a dust suction module 190. The dust suction module 190 may include a dust collection motor 191, a first filter (not shown), and a second filter (not shown).

[0317] 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 flow path section 180. Thus, the dust collection motor 191 can provide suction to draw dust into the dust bin 220 of the vacuum cleaner 200.

[0318] The dust collection motor 191 generates suction by rotating. As an example, the dust collection motor 191 can be formed into a shape similar to a cylinder.

[0319] 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.

[0320] A first filter (not shown) may be configured between the dust collection section 170 and the dust collection motor 191. The first filter may be a pre-filter.

[0321] 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.

[0322] On the other hand, the vacuum cleaner base station 100 may also include a charging unit 128. The charging unit may be disposed on the connecting portion 120. The charging unit 128 may be electrically connected to the vacuum cleaner 200 connected to the connecting portion 120. The charging unit 128 may supply power to the battery of the vacuum cleaner 200 connected to the connecting portion 120.

[0323] Additionally, the vacuum cleaner base station 100 may also include a side door (not shown). The side door may be configured on 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.

[0324] on the other hand, Figure 18 The diagram shows a block diagram illustrating the control configuration in a vacuum cleaner base station according to an embodiment of the present invention.

[0325] Reference Figure 18 This section explains the control configuration of the vacuum cleaner base station 100 of the present invention.

[0326] The vacuum cleaner base station 100 of this embodiment may further include a control unit 400, which controls the connecting part 120, the fixing unit 130, the dust bucket lid control unit 140, the dust collection part 170, the flow path part 180, and the dust suction module 190.

[0327] The control unit 400 may consist of a printed circuit board and components mounted on the printed circuit board.

[0328] When the connection sensor 125 detects the connection of the vacuum cleaner 200, the connection sensor 125 can send a signal that the vacuum cleaner 200 is connected to the connection part 120. At this time, the control unit 400 can receive the signal from the connection sensor 125 and determine that the vacuum cleaner 200 is connected to the connection part 120.

[0329] In addition, when the charging unit 128 supplies power to the battery 240 of the vacuum cleaner 200, the control unit 400 can determine that the vacuum cleaner 200 is connected to the connection unit 120.

[0330] If it is determined that the vacuum cleaner 200 is fixed to the joint 120, the control unit 400 will operate the cover control motor 142 and open the cover control frame 141 of the vacuum cleaner base station 100.

[0331] If it is determined that the vacuum cleaner 200 is fixed to the joint 120, the control unit 400 will operate the cover control motor 142 and open the cover control frame 141 of the vacuum cleaner base station 100.

[0332] When the cover control sensor 144 contacts the first sensing protrusion 1431ca, it can send a signal that the cover control frame 141 is closed. If it is determined that the cover control frame 141 is closed, the control unit 400 will stop the operation of the cover control motor 142.

[0333] When the cover control sensor 144 contacts the second sensing protrusion 1431cb, it can send a signal that the cover control frame 141 has been opened. If it is determined that the cover control frame 141 has been opened, the control unit 400 will stop the operation of the cover control motor 142.

[0334] The control unit 400 can suck up dust from inside the dust bin 220 by driving the dust collection motor 191.

[0335] The control unit 400 can display the dustbin emptying status and charging status of the vacuum cleaner 200 by operating the display unit 410.

[0336] On the other hand, the vacuum cleaner base station 100 of the present invention may include a display unit 410.

[0337] The display unit 410 can be configured on the housing 110, or it can be configured on a separate display device, and can be installed on a terminal including a mobile phone.

[0338] 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 current operation, remaining time, etc., through the information output by the display unit.

[0339] 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.

[0340] 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 configured as a keypad, a dome switch, a touchpad (static / electrostatic), etc. In particular, when the touchpad and the display unit 410 form a layered structure, it may be referred to as a touch screen.

[0341] Figure 19 The diagram shows a flowchart illustrating the control method of the vacuum cleaner system of the present invention.

[0342] Reference Figures 5 to 19 This describes the control method of the vacuum cleaner base station according to an embodiment of the present invention.

[0343] The control method of the vacuum cleaner base station of the present invention includes a combined confirmation step S10, a cover opening step S20, a dust collection step S30, and a cover closing step S40.

[0344] In the connection confirmation step S10, it can be confirmed whether the vacuum cleaner 200 is connected to the connection portion 120 of the vacuum cleaner base station 100.

[0345] Specifically, in the connection confirmation step S10, when the vacuum cleaner 200 is connected to the connection portion 120, the connection sensor 125 can contact the battery cover 230 and send a signal that the vacuum cleaner 200 is connected to the connection portion 120. Alternatively, according to an embodiment, a non-contact connection sensor 125 disposed on the side wall 124 can sense the presence of the dustbin 220 and send a signal that the vacuum cleaner 200 is connected to the connection portion 120.

[0346] Therefore, in the connection confirmation step S10, the control unit 400 can receive the signal generated in the connection sensor 125 and determine whether the vacuum cleaner 200 is connected to the connection part 120.

[0347] Alternatively, in the bonding confirmation step S10 of the present invention, the control unit 400 can sense whether the vacuum cleaner 200 is bonded to a fixed position by whether the charging unit 128 supplies power to the battery 240 of the vacuum cleaner 200.

[0348] In the cover opening step S20, when the dust bin 220 is attached to the vacuum cleaner base station 100, the control unit 400 can open the discharge cover 222 of the vacuum cleaner 200.

[0349] The control unit 400 can fix the dust bin 220 by operating the dust collection motor 191, and can open the discharge cover 222 of the dust bin 220.

[0350] Specifically, when the dust collection motor 191 is running, the fixing member 131 can move towards the dust bin under the suction force of the dust collection motor 191. For example, although not shown, when the dust collection motor 191 is running, a negative pressure can be formed on the fixing member 131 through the pipe connected to the lower side of the fixing member 131. While the fixing member 131 moves towards the dust bin 220, it can pressurize and fix the outer peripheral surface of the dust bin 220.

[0351] Therefore, according to the present invention, the overall operating time can be reduced by reducing the time required to fix or release the vacuum cleaner 200.

[0352] Meanwhile, with the discharge cover 222 closed, negative pressure is created in the flow path 180 under the suction of the dust collection motor 191, and negative pressure is also created in the bypass hole 122c and the cover opening hole 122a that communicate with the flow path 180. As a result, the pressure moving body 510 and the cover opening member 530 can move and pressurize the connecting rod 222c. Consequently, as the connecting rod 222c rotates, the constraint between the discharge cover 222 and the dust bin body 221 is released.

[0353] On the other hand, the discharge cover 222, which is released from its restraints, can rotate away from the dust bin 220 under the force of the torsion spring 222d, but can be controlled by the cover control frame 141.

[0354] On the other hand, in the cover opening step S20, the control unit 400 can open the cover control frame 141.

[0355] Specifically, when a signal is received indicating that the dustbin 220 is engaged, the control unit 400 can rotate the cover control motor 142 in the forward direction and rotate the first link 1431, lifting it upwards. At this time, the first link 1431 can lift one side of the second link 1432, and the other side of the second link 1432 can lift the cover control frame 141. As a result, the cover control frame 141 can rotate while simultaneously opening the dust passage 121a. That is, in the cover opening step S20, the control unit 400 can open the dust passage 121a by rotating the cover control frame 141.

[0356] On the other hand, in this embodiment, after the control unit 400 receives the signal that the dust bin 220 is engaged, and after a preset time, it can cause the cover control motor 142 to run in the forward direction.

[0357] With this configuration, in the lid opening step S20, after the time required for the pressing protrusion 151 to begin pressurizing the connecting rod 222c, the lid control frame 141 can be opened, and the discharge lid 222 and the lid control frame 141 can open at approximately the same time. Therefore, when the lid control frame 141 has first rotated and opened the dust passage 121a, the discharge lid 222 suddenly opens under the restoring force of the torsion spring 222d, and at the same time, the lid control frame 141 and the discharge lid 222 collide violently. Alternatively, even if the hook engagement between the discharge lid 222 and the dust bin body 221 is released, the lid control frame 141 will not open, thereby preventing the discharge lid 222 and the dust bin body 221 from not separating.

[0358] As a result, when the cover opening step S20 is performed, the discharge cover 222 of the dust bin 220 can rotate to open the space inside the dust bin body 221, and the cover control frame 141 can rotate to open the dust passage 121a, so that the internal space of the dust bin 220 can be connected to the flow path 180 (specifically, the first flow path 181) of the vacuum cleaner base station 100.

[0359] On the other hand, when the cover control sensor 144 senses the second sensing protrusion 1431cb, it can send a corresponding signal. Therefore, the control unit 400 can determine that the cover control frame 141 is open and can stop the operation of the cover control motor 142.

[0360] In contrast, according to the embodiment, the control unit 400 can make the cover control motor 142 run for a preset time. As an example, the control unit 400 can also make the cover control motor 142 run in the forward direction for a period of more than 5 seconds and less than 7 seconds before stopping the operation of the cover control motor 142.

[0361] Alternatively, according to an embodiment, when the connecting rod 143 contacts the connecting rod stop 115, the control unit 400 can sense the load on the cover control motor 142 and stop the operation of the cover control motor 142.

[0362] At this point, the control unit 400 can proceed to the dust collection step S30.

[0363] In the dust collection step S30, dust inside the dust bin 220 can be collected by running the dust collection motor 191.

[0364] As an example, after the cover opening step S20, the control unit 400 can keep the dust collection motor 191 running.

[0365] In the dust collection step S30, the control unit 400 can operate the dust collection motor 191 at a preset dust collection speed within a preset dust collection time. As an example, in the dust collection step S30, after the cover control frame 141 is opened, the control unit 400 can operate the dust collection motor 191 at the preset dust collection speed for a period of 5 to 9 seconds, but it is not limited to this. The dust collection time can be changed and set according to the output of the dust collection motor 191 and the amount of dust stored inside the dust bin 220.

[0366] According to the dust collection step S30, the dust inside the dust bin 220 can be collected into the dust collection section 170 through the dust through-hole 121a and the flow path 180. Therefore, the user can remove the dust inside the dust bin 220 without additional operation, thus providing convenience to the user.

[0367] On the other hand, in the control method of the vacuum cleaner base station according to an embodiment of the present invention, a cover closing step S40 may also be included. The cover closing step S40 is a step of sealing the dust passage 121a by rotating the cover control frame 141 after the dust collection motor 191 has finished operating. That is, in the cover closing step S40, when the dust collection motor 191 has finished operating, the connecting rod 143 can rotate again.

[0368] In the lid closing step S40, the control unit 400 can cause the lid control motor 142 to operate in the opposite direction to the operating direction of the lid control motor 142 in the lid opening step S20.

[0369] Specifically, in the lid opening step S20, the first link 1431 is engaged with the second link stop 115b, and the lid control sensor 144 senses the second sensing protrusion 1431cb, thereby stopping the operation of the lid control motor 142 which is operating in the forward direction. Then, in the lid closing step S40, the lid control motor 142 is turned in the reverse direction.

[0370] That is, in the cover closing step S40, the control unit 400 can change the rotation direction of the shaft of the cover control motor 142.

[0371] For example, after the dust collection motor 191 has finished running, the control unit 400 can rotate the cover control frame 141 by turning the cover control motor 142 in the opposite direction.

[0372] Specifically, after the dust collection motor 191 finishes operating, the control unit 400 can rotate the first link 1431 downwards by reversing the rotation of the cover control motor 142. At this time, the first link 1431 can lower one side of the second link 1432, and the other side of the second link 1432 can lower the cover control frame 141. As a result, the cover control frame 141 can rotate while simultaneously closing the dust passage 121a. That is, in the cover closing step S40, the control unit 400 can close the dust passage 121a by rotating the cover control frame 141.

[0373] At this time, when the cover control sensor 144 senses the first sensing protrusion 1431ca, it can send a corresponding signal. Therefore, the control unit 400 can determine that the cover control frame 141 closes the dust passage 121a and stops the operation of the cover control motor 142.

[0374] In contrast, according to the embodiment, the control unit 400 can make the cover control motor 142 run for a preset time. As an example, the control unit 400 can also stop the operation of the cover control motor 142 after running it in the reverse direction for more than 5 seconds and less than 7 seconds.

[0375] Therefore, according to the present invention, when the first link 1431 is engaged with the link stop 115, the control unit 400 can then precisely control the movement of the cover control frame 141 by changing the operating direction of the cover control motor 142, thereby achieving the effect of controlling the discharge cover 222 even without using an encoder or the like.

[0376] Furthermore, according to the present invention, while the dust collection motor 191 is running, the cover control frame 141 is moved to open the discharge cover 222 of the dust bin, and while the dust collection motor 191 is running, the discharge cover 222 is closed, thereby reducing the time required for dust collection in the dust bin 220.

[0377] The present invention has been described in detail above through specific embodiments, but this is only for the purpose of illustrating the present invention. The present invention is not limited thereto, and it is obvious that those skilled in the art can modify or improve the present invention within the technical concept of the present invention.
