Description

Technical Field

[0001] The present invention relates to a vacuum cleaner base station, and more particularly, to a vacuum cleaner base station that is combined with a vacuum cleaner to suck dust stored in the vacuum cleaner into the interior. Background Art

[0002] Generally, a vacuum cleaner is a household appliance that uses electricity to suck in air to suck in smaller garbage or dust and fills the dust barrel inside the product, and is usually called a vacuum cleaner.

[0003] Such vacuum cleaners can be divided into manual vacuum cleaners that the user directly moves the vacuum cleaner to perform cleaning, and automatic vacuum cleaners that move and perform cleaning autonomously. Manual vacuum cleaners can be divided into canister-type vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick-type vacuum cleaners according to the shape of the vacuum cleaner.

[0004] Conventionally, most household vacuum cleaners are cylinder-type vacuum cleaners. However, in recent years, handheld vacuum cleaners and stick-type vacuum cleaners are increasingly being used, in which the dust container and the vacuum cleaner body are integrated to improve the usability.

[0005] In a cylinder-type vacuum cleaner, a main body and a suction port are connected by a rubber hose or a pipe, and a brush can be mounted on the suction port for use according to circumstances.

[0006] A handheld vacuum cleaner is a vacuum cleaner that maximizes portability. Although it is lightweight, it is short and requires squatting to clean, so the cleaning area is limited. Therefore, it is used to clean local places such as desks, sofas, or cars.

[0007] A stick vacuum cleaner can be used while standing, so it can be cleaned without bending over. Therefore, it is convenient to move and clean in a wide area. Compared with a handheld vacuum cleaner that cleans a narrow space, a stick vacuum cleaner can clean a wider space and can clean high places that cannot be reached by hand. In recent years, stick vacuum cleaners have been provided in a modular form to actively change the type of vacuum cleaner and use it for various objects.

[0008] In addition, recently, a cleaning robot that performs cleaning autonomously without user operation is being used. The cleaning robot automatically cleans the area to be cleaned by sucking in foreign matter such as dust from the ground while autonomously traveling in the area to be cleaned.

[0009] To this end, the sweeping robot has a distance sensor, a left wheel and a right wheel. The distance sensor senses the distance to obstacles such as furniture, office supplies or walls set in the cleaning area, and the left wheel and the right wheel are used for the movement of the sweeping robot.

[0010] Here, the left wheel is configured to rotate using a left wheel motor, and the right wheel is configured to rotate using a right wheel motor. The cleaning robot automatically changes direction to perform indoor cleaning as the left and right wheel motors are driven.

[0011] However, in the existing handheld vacuum cleaners, stick vacuum cleaners and sweeping robots, the dust bucket for storing the collected dust has a small capacity, so there is the inconvenience of the user needing to empty the dust bucket every time.

[0012] In addition, when the dust barrel is emptied, there is a problem that dust is scattered and adversely affects the health of the user.

[0013] In addition, when the residual dust in the dust bucket is not removed, there is a problem that the suction power of the vacuum cleaner is reduced.

[0014] In addition, when the residual dust in the dust barrel is not removed, there is a problem of generating odor due to the residual dust.

[0015] On the other hand, the existing patent document JP2017-189453 discloses a base station device for collecting dust from a handheld vacuum cleaner.

[0016] The extension pipe, suction port and dust bucket of the vacuum cleaner are arranged side by side, and the structure of the base station device combined with the dust bucket of the vacuum cleaner is arranged to face upward. That is, the vacuum cleaner is placed on the upper part of the base station.

[0017] However, the base station can only be combined with a handheld vacuum cleaner, and does not have a structure capable of combining with a cleaning robot to collect dust stored in a dust bucket of the cleaning robot, so there is a limitation.

[0018] On the other hand, the existing patent document US10595692B2 discloses a discharge base station having a dust bin of a sweeping robot.

[0019] In the prior art patent document, a base station docked with the sweeping robot is provided, and the base station forms a flow path for sucking dust in a direction perpendicular to the ground.

[0020] In the base station, a dust collecting motor for sucking dust from the cleaning robot is arranged on the upper side of the base station.

[0021] However, the base station can only be combined with a cleaning robot, and does not have a structure capable of combining with a stick vacuum cleaner to collect dust stored in the stick vacuum cleaner, so there is a limitation.

[0022] In addition, the portion of the flow path of the base station connected to the dust bag is formed in a direction parallel to the ground. In this case, if the motor stops running, residual dust may remain on the flow path, and part of the dust may flow back and fly to the outside, so there is a limitation.

[0023] On the other hand, the existing patent document KR2022-0006850A discloses a vacuum cleaner base station that is combined with a handheld stick vacuum cleaner and / or a sweeping robot to collect dust.

[0024] The vacuum cleaner base station has a first flow path, a second flow path and a flow path conversion valve. Dust in the dust bucket of a handheld stick vacuum cleaner flows in the first flow path, and dust in the dust bucket of a sweeping robot flows in the second flow path. The flow path conversion valve selectively opens and closes the first flow path and the second flow path.

[0025] However, the vacuum cleaner base station does not disclose the specific structure of the vacuum cleaner base station combined with the sweeping robot, and thus, the structure of the second flow path is not disclosed.

[0026] Furthermore, the specific flow path configuration of the first flow path and the second flow path and the structure for selectively opening and closing the first flow path and the second flow path are not disclosed.

[0027] Therefore, the vacuum cleaner base station fails to propose a structure that minimizes the occupied volume when both the handheld stick vacuum cleaner and the cleaning robot are combined, and thus has limitations.

[0028] In addition, although the cleaner base station has a structure for selectively connecting the flow path of air flowing in from the handheld stick cleaner and the flow path of air flowing in from the cleaning robot, it fails to propose a flow path structure that minimizes flow path loss to maximize the dust collection function, and thus has limitations. Summary of the invention

[0029] Problem that the invention aims to solve

[0030] The present invention is proposed to improve the above-mentioned problems of the existing vacuum cleaner system, and its purpose is to provide a vacuum cleaner base station that can eliminate the trouble of requiring users to frequently empty the dust bin.

[0031] In addition, it is an object to provide a vacuum cleaner base station that enables a vacuum cleaner to be combined with a side of the base station, thereby increasing space efficiency by minimizing the horizontal space occupied indoors.

[0032] In addition, the present invention aims to provide a vacuum cleaner base station capable of combining a handheld stick vacuum cleaner and a cleaning robot.

[0033] In addition, it is an object to provide a vacuum cleaner base station that minimizes the loss of flow force for collecting dust.

[0034] Another object is to provide a vacuum cleaner base station in which dust is not scattered but is quickly sucked into a dust collecting portion during the process of emptying the dust barrel.

[0035] In addition, the present invention aims to provide a vacuum cleaner base station that can remove dust in a dust bin without additional operation by the user, thereby providing convenience to the user.

[0036] Another object is to provide a vacuum cleaner base station that prevents residual dust from remaining in the dust bin and can remove bad odors caused by the residual dust.

[0037] Another object is to provide a vacuum cleaner base station that allows a user to connect the vacuum cleaner to the base station without bending over.

[0041] At this time, the first vacuum cleaner flow path may include: a first flow path, which is connected to the internal space of the dust bin when the discharge cover of the dust bin is open; and a second flow path, which is connected to the first flow path and the dust collecting flow path and forms a specified angle with the first flow path.

[0042] In this case, the second flow path may be configured to be inclined at a predetermined dust inflow angle with respect to a vertical line perpendicular to the ground.

[0043] At this time, the dust inflow angle may be greater than 0 degrees and less than 10 degrees.

[0044] On the other hand, the flow path portion may further include a flow path conversion module, and the flow path conversion module selectively connects the first cleaner flow path or the second cleaner flow path to the dust collection flow path.

[0045] The second flow path may be arranged to be inclined at a predetermined dust inflow angle with respect to the dust collecting flow path.

[0046] When the vacuum cleaner is combined with the vacuum cleaner base station, a virtual dust bin penetration line that penetrates the dust bin along the length direction may intersect a virtual first vacuum cleaner flow path penetration line that penetrates the second flow path along the length direction inside the flow path portion.

[0047] The dust container penetration line and a virtual dust collecting flow path penetration line penetrating the dust collecting flow path in the length direction may intersect inside the flow path portion.

[0048] On the other hand, the second vacuum cleaner flow path may include: a third flow path connected to the dust suction hole; a fourth flow path connected to the third flow path and formed in a direction perpendicular to the ground; and a fifth flow path connected to the fourth flow path and formed to form a specified angle with the fourth flow path.

[0049] In addition, one end portion of the fifth flow path connected to the fourth flow path is arranged at a position farther from the ground than the other end portion connected to the flow path switching module.

[0050] In addition, the diameter of the fifth flow path may be greater than the diameter of the fourth flow path.

[0051] In addition, the fifth flow path may be arranged at a position closer to the ground than the first cleaner flow path and farther from the ground than the dust collecting flow path.

[0052] In order to achieve the above-mentioned purpose, the vacuum cleaner base station of the present invention may include: a cover body; a coupling part, which is arranged on the cover body, including a coupling surface coupled to at least a part of the first vacuum cleaner; a lower coupling part, which is arranged at a position closer to the ground than the coupling part, and the second vacuum cleaner is coupled to the lower coupling part; a dust collecting part, which is accommodated inside the cover body and arranged between the coupling part and the lower coupling part, and the dust collecting part captures dust; and a flow path part, which is formed inside the cover body, and has a flow path that allows the internal space of the dust bucket of the first vacuum cleaner or the internal space of the dust bucket of the second vacuum cleaner to be connected with the inside of the dust collecting part The flow path is connected to the space; the flow path part may include: a first vacuum cleaner flow path, which connects the dust through hole formed in the connecting part with the internal space of the dust collecting part; a second vacuum cleaner flow path, which connects the dust suction hole formed in the lower connecting part with the internal space of the dust collecting part; a dust collecting flow path, which is arranged at a position closer to the ground than the first vacuum cleaner flow path and is connected to the internal space of the dust collecting part; and a flow path conversion module, which is arranged between the first vacuum cleaner flow path and the dust collecting flow path, and the flow path conversion module selectively connects the first vacuum cleaner flow path or the second vacuum cleaner flow path with the dust collecting flow path.

[0053] At this time, the first vacuum cleaner flow path may include: a first flow path, which is connected to the dust through hole and formed in a direction parallel to the ground; and a second flow path, which is arranged between the first flow path and the flow path conversion module and is formed to be inclined at a specified dust inflow angle with respect to a vertical line perpendicular to the ground.

[0054] In addition, the second vacuum cleaner flow path may include: a third flow path, which is connected to the dust suction hole and formed in a direction parallel to the ground; a fourth flow path, which is connected to the third flow path and formed in a direction perpendicular to the ground; and a fifth flow path, which is connected to the fourth flow path and formed to form a specified angle with the fourth flow path.

[0055] On the other hand, the flow path portion may further include a connecting hose, which is arranged inside the flow path conversion module, one end of the connecting hose is connected to the first vacuum cleaner flow path or the second vacuum cleaner flow path, and the other end is connected to the dust collection flow path.

[0056] One end portion of the connecting hose may be further away from the ground than the other end portion of the connecting hose.

[0057] Effects of the Invention

[0058] As described above, the vacuum cleaner base station according to the present invention has the following effect: if the user combines the vacuum cleaner with the vacuum cleaner base station, the combination of the vacuum cleaner can be detected without additional operation by the user, and the dust in the dust bucket can be removed, thereby providing user convenience.

[0059] In addition, when the dust container is emptied, the dust in the dust container is sucked into the base station as the dust collecting motor is operated, thereby preventing the dust from scattering.

[0060] In addition, the stick vacuum cleaner is combined with the side of the vacuum cleaner base station and the sweeping robot is combined with the bottom of the vacuum cleaner base station to minimize the horizontal space occupied by the vacuum cleaner system in the room, thereby increasing space efficiency.

[0061] In addition, the stick vacuum cleaner and the cleaning robot can be combined at the same time, and dust in the dust bucket of the stick vacuum cleaner and the dust bucket of the cleaning robot can be selectively removed as needed.

[0062] In addition, the flow path connected to the dust bin of the stick vacuum cleaner is bent downward once, so that the flow path leading air to the dust collecting part is formed at a predetermined angle, thereby minimizing the loss of flow force for collecting dust.

[0063] In addition, the flow path connected to the dust bin of the cleaning robot is formed at a specified angle, so that even if foreign matter discharged from the dust bin of the cleaning robot overcomes gravity and flows, backflow can be prevented and sufficient dust collecting power can be provided.

[0064] In addition, there is an effect that the user can easily connect the vacuum cleaner to the base station without bending over. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 5 A diagram showing the weight distribution of the vacuum cleaner base station and the angle of a flow path of the vacuum cleaner base station using virtual lines according to an embodiment of the present invention.

[0086] Reference Figure 1 and Figure 5 The vacuum cleaner system 10 of one embodiment of the present invention may include a vacuum cleaner base station 100 and vacuum cleaners 200 and 300. At this time, the vacuum cleaners 200 and 300 may include a first vacuum cleaner 200 and a second vacuum cleaner 300. On the other hand, in this embodiment, a part of the configuration may be removed for implementation, and additional configurations are not excluded.

[0087] The dust removal system 10 may include a vacuum cleaner base station 100. The first vacuum cleaner 200 and the second vacuum cleaner 300 may be combined at the vacuum cleaner base station 100. The first vacuum cleaner 200 may be combined at the side of the vacuum cleaner base station 100. Specifically, the main body of the first vacuum cleaner 200 may be combined at the side of the vacuum cleaner base station 100. The second vacuum cleaner 300 may be combined at the lower part of the vacuum cleaner base station 100.

[0088] on the other hand, Figure 2 A diagram showing a first dust collector in a dust removal system for explaining an embodiment of the present invention is shown. Figure 3 FIG. 1 shows a diagram for explaining the weight distribution of the first vacuum cleaner according to the embodiment of the present invention using virtual lines and virtual planes, Figure 4 A diagram showing the lower side of a dust container of a first vacuum cleaner for explaining an embodiment of the present invention is shown.

[0089] First, refer to Figures 1 to 5 , the structure of the first vacuum cleaner 200 is described as follows.

[0090] The first vacuum cleaner 200 may represent a vacuum cleaner manually operated by a user. For example, the first vacuum cleaner 200 may represent a handheld vacuum cleaner or a stick vacuum cleaner.

[0091] The first vacuum cleaner 200 may be placed on the vacuum cleaner base station 100. The first vacuum cleaner 200 may be supported by the vacuum cleaner base station 100. The first vacuum cleaner 200 may be combined with the vacuum cleaner base station 100.

[0092] On the other hand, in one embodiment of the present invention, the direction of the vacuum cleaner 200 may be defined based on the condition that the dust bin 220 and the bottom surface (lower side) of the battery cover 230 are placed on the ground.

[0093] At this time, the front may indicate the direction in which the suction unit 212 is configured with the suction motor 214 as a reference, and the rear may indicate the direction in which the handle 216 is configured with the suction motor 214 as a reference. Furthermore, the direction configured on the right with reference to the situation of observing the suction unit 212 from the suction motor 214 may be referred to as the right side, and the direction configured on the left may be referred to as the left side. In addition, in one embodiment of the present invention, the upper side and the lower side may be defined in a direction perpendicular to the ground with reference to the situation in which the bottom surface (lower side) of the dust bin 220 and the battery cover 230 are placed on the ground.

[0094] The first cleaner 200 may include a main body 210 . The main body 210 may include a main body cover 211 , a suction part 212 , a dust separation part 213 , a suction motor 214 , an air discharge cover 215 , a handle 216 , and an operation part 218 .

[0095] The main body cover 211 may form the appearance of the first vacuum cleaner 200. The main body cover 211 may provide a space capable of accommodating a suction motor 214 and a filter (not shown) inside. The main body cover 211 may be configured in a shape similar to a cylinder.

[0096] The suction part 212 may protrude outward from the main housing 211. As an example, the suction part 212 may be formed in a cylindrical shape with an internal opening. The suction part 212 may be combined with the extension pipe 250. The suction part 212 may provide a flow path (hereinafter, referred to as "suction flow path") through which air containing dust may flow.

[0097] On the other hand, in this embodiment, a virtual line penetrating the inside of the cylindrical suction portion 212 may be formed. That is, a virtual suction flow path penetrating line a2 penetrating the suction flow path in the longitudinal direction may be formed.

[0098] As an example, the suction flow path penetration line a2 may be a virtual line connecting the centers of circles that appear when the cylindrical suction portion 212 is radially cut in the longitudinal direction (axial direction).

[0099] The dust separation part 213 may be communicated with the suction part 212. The dust separation part 213 may separate the dust sucked into the inside through the suction part 212. The space inside the dust separation part 213 may be communicated with the space inside the dust barrel 220.

[0100] For example, the dust separation unit 213 may have at least two cyclone units, and the cyclone units can separate dust by using cyclone flow. In addition, the space inside the dust separation unit 213 may be connected to the suction flow path. Therefore, the air and dust sucked by the suction unit 212 may flow in a spiral along the inner circumference of the dust separation unit 213. Therefore, a cyclone flow may be generated in the internal space of the dust separation unit 213.

[0101] On the other hand, in the present embodiment, a virtual cyclone line a4 extending in the up-down direction of the dust separation portion 213 generating the cyclone flow may be formed.

[0102] The suction motor 214 may generate suction force for sucking in air. The suction motor 214 may be accommodated in the main housing 211. The suction motor 214 may include an impeller that generates suction force by rotating. As an example, the suction motor 214 may have a shape similar to a cylinder.

[0103] On the other hand, in the embodiment, a virtual suction motor axis a1 extending the rotation axis of the suction motor 214 may be formed.

[0104] The air outlet cover 215 may be disposed on one axial side of the main housing 211. A filter for filtering air may be accommodated in the air outlet cover 215. As an example, a high efficiency air (HEPA) filter may be accommodated in the air outlet cover 215.

[0105] The air discharge cover 215 may be formed with an air discharge port 215 a for discharging air sucked by the suction force of the suction motor 214 .

[0106] A flow guide may be provided at the air discharge cover 215. The flow guide may guide the flow of the air discharged through the air discharge port 215a.

[0107] The handle 216 can be held by the user. The handle 216 can be arranged behind the suction motor 214. As an example, the handle 216 can be formed in a shape similar to a cylinder. Alternatively, the handle 216 can be formed in a curved cylindrical shape. The handle 216 can form a specified angle with the main cover 211, the suction motor 214, or the dust separation unit 213.

[0108] The handle 216 may include: a gripping portion 216a, formed in a columnar shape so that the user can grip it; a first extension portion 216b, connected to one side end portion of the gripping portion 216a in the length direction (axial direction), extending toward the suction motor 214; and a second extension portion 216c, connected to the other side end portion of the gripping portion 216a in the length direction (axial direction), extending toward the dust bin 220.

[0109] On the other hand, in this embodiment, a virtual gripping portion penetration line a3 extending along the length direction of the gripping portion 216a (the axial direction of the column) and penetrating the gripping portion 216a may be formed.

[0110] As an example, the grip portion penetration line a3 may be a virtual line formed inside the cylindrical handle 216, or may be a virtual line formed parallel to at least a portion of the outer side surface (outer peripheral surface) of the grip portion 216a.

[0111] The top surface of the handle 216 may form a portion of the top surface of the first cleaner 200. Thus, when the user holds the handle 216, a portion of the first cleaner 200 may be prevented from contacting the user's arm.

[0112] The first extension portion 216b may extend from the grip portion 216a toward the main body housing 211 or the suction motor 214. At least a portion of the first extension portion 216b may extend in a horizontal direction.

[0113] The second extension portion 216c may extend from the grip portion 216a toward the dust container 220. At least a portion of the second extension portion 216c may extend in a horizontal direction.

[0114] The operation part 218 may be disposed on the handle 216. The operation part 218 may be disposed on an inclined surface formed in an upper region of the handle 216. The user may input an operation or stop command of the first cleaner 200 through the operation part 218.

[0115] The first cleaner 200 may include a dust container 220. The dust container 220 may be in communication with the dust separation portion 213. The dust container 220 may store dust separated from the dust separation portion 213.

[0116] The dust bin 220 may include a dust bin body 221 , a discharge cover 222 , a dust bin compression rod 223 , and a compression member (not shown).

[0117] The dust container body 221 may provide a space capable of storing dust separated from the dust separation portion 213. As an example, the dust container body 221 may be formed in a shape similar to a cylinder.

[0118] On the other hand, in this embodiment, a virtual dust bin penetration line a5 can be formed that penetrates the interior (internal space) of the dust bin body 221 and extends along the length direction of the dust bin body 221 (referring to the axial direction of the cylindrical dust bin body 221).

[0119] At this time, the dust bin penetration line a5 includes points on the plane displayed when the dust bin 220 is radially cut in the length direction (axial direction in the cylindrical dust bin body 221), and the dust bin penetration line a5 can be a virtual line perpendicular to the plane.

[0120] As an example, the dust container penetration line a5 may be a virtual line that passes through the center of a circle displayed when the dust container 220 is radially cut in the length direction thereof and is perpendicular to the circle.

[0121] A portion of the lower side (bottom) of the dust barrel body 221 may be open. In addition, a bottom surface extension portion 221a may be formed on the lower side (bottom) of the dust barrel body 221. The bottom surface extension portion 221a may be formed to block a portion of the lower side of the dust barrel body 221.

[0122] 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. The discharge cover 222 may selectively open and close the lower portion of the dust bin 220 that is open downward.

[0123] The discharge cover 222 may include a cover body 222a and a hinge portion 222b. The cover body 222a may be formed to block a portion of the lower side of the dust bin body 221. The cover body 222a may rotate downward with the hinge portion 222b as a reference. The hinge portion 222b may be arranged adjacent to the battery cover 230. A torsion spring 222d may be provided at the hinge portion 222b. Therefore, when the discharge cover 222 is separated from the dust bin body 221, due to the elastic force of the torsion spring 222d, the cover body 222a may be supported in a state where it is rotated from the dust bin body 221 to a predetermined angle or more with the hinge portion 222b as an axis.

[0124] The discharge cover 222 may be coupled with the dust container 220 by hook coupling.

[0125] On the other hand, the dust bin may further include a coupling rod 222c. The discharge cover 222 may be separated from the dust bin 220 by the coupling rod 222c. The coupling rod 222c may be disposed in front of the dust bin. Specifically, the coupling rod 222c may be disposed on the outer side of the front side of the dust bin 220. When an external force is applied, the coupling rod 222c may elastically deform the hook extending from the cover body 222a to release the hook coupling between the cover body 222a and the dust bin body 221.

[0126] When the discharge cover 222 is closed, the lower side of the dust container 220 may be blocked (sealed) by the discharge cover 222 and the bottom surface extension 221 a.

[0127] The dust bucket 220 may include a dust bucket compression rod 223. The dust bucket compression rod 223 may be disposed outside the dust bucket 220 or the dust separation portion 213. The dust bucket compression rod 223 may be disposed outside the dust bucket 220 or the dust separation portion 213 movably up and down. The dust bucket compression rod 223 may be connected to a compression member (not shown). In the case where the dust bucket compression rod 223 is moved downward by an external force, the compression member (not shown) may also move downward together. Thus, user convenience may be provided. The compression member (not shown) and the dust bucket compression rod 223 may be reset to their original positions by an elastic member (not shown). Specifically, in the case where the external force applied to the dust bucket compression rod 223 is released, the elastic member may enable the dust bucket compression rod 223 and the compression member (not shown) to move upward.

[0128] A compression member (not shown) may be disposed inside the dust bin body 221. The compression member may move in the internal space of the dust bin body 221. Specifically, the compression member may move up and down inside the dust bin body 221. Thus, the compression member may compress the dust inside the dust bin body 221 downward. In addition, when the discharge cover 222 is separated from the dust bin body 221 and the lower portion of the dust bin 220 is open, the compression member moves from the upper portion to the lower portion of the dust bin 220, thereby being able to remove foreign matter such as residual dust inside the dust bin 220. Thus, the suction force of the vacuum cleaner may be increased by preventing the residual dust from remaining inside the dust bin 220. Furthermore, by preventing the residual dust from remaining inside the dust bin 220, the odor generated by the residual matter may be removed.

[0129] The first vacuum cleaner 200 may include a battery cover 230. The battery cover 230 may accommodate a battery 240. The battery cover 230 may be disposed on the lower side of the handle 216. As an example, the battery cover 230 may be in a hexahedral shape with an open lower portion. The back of the battery cover 230 may be connected to the handle 216.

[0130] The battery cover 230 may include a receiving portion open downward, and the battery 240 may be loaded and unloaded through the receiving portion of the battery cover 230 .

[0131] The first cleaner 200 may include a battery 240 .

[0132] For example, the battery 240 may be detachably coupled to the first vacuum cleaner 200. The battery 240 may be detachably coupled to the battery cover 230. As an example, the battery 240 may be inserted into the battery cover 230 from below. With this configuration, the portability of the first vacuum cleaner 200 may be improved.

[0133] Alternatively, the battery 240 may be provided integrally with the battery cover 230 inside the battery cover 230. In this case, the bottom surface of the battery 240 is not exposed to the outside.

[0134] The battery 240 can supply power to the suction motor 214 of the first vacuum cleaner 200. The battery 240 can be arranged at the bottom of the handle 216. The battery 240 can be arranged behind the dust bin 220. That is, the suction motor 214 and the battery 240 can be arranged so as not to overlap in the up and down directions, and the arrangement heights can also be different from each other. With the handle 216 as a reference, the heavier suction motor 214 is arranged in front of the handle 216, and the heavier battery 240 is arranged below the handle 216, so that the overall weight of the first vacuum cleaner 200 can be evenly distributed. Thereby, it is possible to prevent the user's wrist from being burdened when the user holds the handle 216 for cleaning.

[0135] According to an embodiment, when the battery 240 is combined with the battery cover 230, the bottom surface of the battery 240 may be exposed to the outside. When the first vacuum cleaner 200 is placed on the floor, the battery 240 may be placed on the floor, so the battery 240 may be directly separated from the battery cover 230. In addition, the bottom surface of the battery 240 is exposed to the outside and directly contacts the outside air of the battery 240, so the cooling performance of the battery 240 may be improved.

[0136] On the other hand, when the battery 240 and the battery cover 230 are fixed integrally, the structure for loading and unloading the battery 240 and the battery cover 230 can be reduced, so the overall size of the first vacuum cleaner 200 can be reduced and lightweight can be achieved.

[0137] The first cleaner 200 may include an extension pipe 250. The extension pipe 250 may be in communication with the cleaning module 260. The extension pipe 250 may be in communication with the main body 210. The extension pipe 250 may be in communication with the suction part 212 of the main body 210. The extension pipe 250 may be formed in a long cylindrical shape.

[0138] The main body 210 may be connected to the extension tube 250. The main body 210 may be connected to the cleaning module 260 through the extension tube 250. The main body 210 generates suction through the suction motor 214, and may provide suction to the cleaning module 260 through the extension tube 250. External dust may flow into the main body 210 through the cleaning module 260 and the extension tube 250.

[0139] The first cleaner 200 may include a cleaning module 260. The cleaning module 260 may be in communication with the extension tube 250. Therefore, external air may flow into the main body 210 of the first cleaner 200 via the cleaning module 260 and the extension tube 250 under the effect of the suction force generated by the main body 210 of the first cleaner 200.

[0140] The dust in the dust bucket 220 of the first vacuum cleaner 200 can be captured in the dust collecting unit 170 of the vacuum cleaner base station 100 under the action of gravity and the suction force of the dust collecting motor 191. Thus, the dust in the dust bucket can be removed without the user's additional operation, thereby improving user convenience. In addition, the trouble of the user frequently emptying the dust bucket can be eliminated. In addition, dust can be prevented from scattering when the dust bucket is emptied.

[0141] The first vacuum cleaner 200 may be combined with the side of the cover body 110. Specifically, the main body 210 of the first vacuum cleaner 200 may be placed on the joint part 120. More specifically, the dust bucket 220 and the battery cover body 230 of the first vacuum cleaner 200 may be combined with the joint surface 121, the outer peripheral surface of the dust bucket main body 221 may be combined with the dust bucket guide surface 122, and the suction part 212 may be combined with the suction part guide surface 126 of the joint part 120. In this case, the central axis of the dust bucket 220 may be arranged in a direction parallel to the ground, and the extension tube 250 may be arranged in a direction perpendicular to the ground.

[0142] on the other hand, Figure 5 A three-dimensional view of a dust bucket of a second vacuum cleaner for illustrating an embodiment of the present invention is shown. Figure 6 Shows the decomposition Figure 5 A three-dimensional view of the second vacuum cleaner discharge cover.

[0143] Reference Figures 1 to 7 , the description of the second vacuum cleaner 300 is as follows.

[0144] The vacuum cleaner system 10 may include a second vacuum cleaner 300. The second vacuum cleaner 300 may represent a sweeping robot. The second vacuum cleaner 300 may automatically clean the area to be cleaned by sucking in foreign matter such as dust from the ground while autonomously driving in the area to be cleaned. The sweeping robot of the second vacuum cleaner 300 may include: a distance sensor for sensing the distance from obstacles such as furniture or office supplies or walls set in the cleaning area; left wheels and right wheels for moving the sweeping robot. The second vacuum cleaner 300 may be combined with a vacuum cleaner base station. The dust in the second vacuum cleaner 300 may be captured into the dust collecting section 170 through the second vacuum cleaner flow path 182.

[0145] The second vacuum cleaner 300 may include a dust bucket 310. The dust bucket 310 may collect foreign matter such as dust. As an example, the dust bucket 310 may be formed in a cylindrical shape. At this time, the bottom surface (lower side) of the dust bucket 310 may be selectively opened and closed. For example, a dust bucket cover 340 may be hingedly combined with the lower side of the dust bucket 310, and if the dust bucket cover 340 is opened, the internal space of the dust bucket 310 may be opened. With the above configuration, the user can directly open the dust bucket cover 340 to empty the dust captured in the dust bucket 310.

[0146] Although not shown in the figure, a dust separation unit may be disposed inside the dust barrel 310. For example, the dust separation unit may have at least two cyclone units, and the cyclone units may separate dust using cyclonic flow. Therefore, the air and dust sucked into the dust barrel may flow in a spiral along the inner circumference of the dust separation unit and be separated.

[0147] On the other hand, the second cleaner 300 may be coupled to the lower coupling portion 160 of the cleaner base station 100 . The dust sucked into the dust container 310 of the second cleaner 300 may be collected toward the dust collecting portion 170 through the second cleaner flow path 182 .

[0148] The second vacuum cleaner 300 may include a dust discharge hole 320. At this time, the dust discharge hole 320 may be arranged on the side (peripheral surface) of the dust barrel 310 of the second vacuum cleaner 300, thereby the dust barrel 310 of the second vacuum cleaner 300 may be connected to the second vacuum cleaner flow path 182. As an example, the dust discharge hole 320 may be in the form of a square hole.

[0149] The second cleaner 300 may include a second cleaner discharge cover 330. At this time, the second cleaner discharge cover 330 is formed in a shape corresponding to the dust discharge hole 320 to close the dust discharge hole 320. To this end, the second cleaner discharge cover 330 may be configured at the dust discharge hole 320.

[0150] In addition, the second vacuum cleaner discharge cover 330 can be hinged with the dust barrel 310, and the dust discharge hole 320 is opened and closed as it rotates around the hinge pin 331. At this time, the hinge pin 331 is provided with a torsion spring 332, so that a restoring force can be applied when the second vacuum cleaner discharge cover 330 is opened.

[0151] With such a configuration, when the dust collecting motor 191 generates suction, the dust discharge hole 320 may be opened as the second cleaner discharge cover 330 rotates toward the outside of the dust container 310 .

[0152] In addition, if the dust collecting motor 191 stops driving, the second vacuum cleaner discharge cover 330 can rotate toward the dust bin 310 under the action of the restoring force of the torsion spring 332 to re-block the dust discharge hole 320. In this way, the second vacuum cleaner discharge cover 330 can rotate with the driving of the dust collecting motor 191 and connect or close the dust bin 310 of the second vacuum cleaner 300 and the second vacuum cleaner flow path 182.

[0153] On the other hand, a seal 333 may be provided on the dust bin 310. The seal 333 may be arranged along the outer contour of the dust discharge hole 320. The seal 333 may be in contact with the discharge cover 330. With the above configuration, when the discharge cover 330 closes the dust discharge hole 320, the seal 333 makes the dust bin 310 and the discharge cover 330 airtight, thereby preventing dust from flowing out.

[0154] In addition, when the second cleaner 300 is coupled to the lower coupling portion 160, the seal 333 may contact the side wall of the lower coupling portion 160. Therefore, under the action of the seal 333, the outer peripheral surface of the dust container 310 of the second cleaner 300 and the lower coupling portion 160 may be airtight. With such a configuration, dust flowing into the dust suction hole 162 can be prevented from scattering to the outside through the dust discharge hole 320.

[0155] The second vacuum cleaner 300 may include a corresponding terminal (not shown) for charging the battery when combined with the lower combining part 160. The corresponding terminal may be configured at a position that is contactable with a charging terminal (not shown) of the lower combining part 160 of the lower combining part 160 when the second vacuum cleaner 300 is combined. As an example, the corresponding terminal may be configured as a pair on the top surface of the second vacuum cleaner 300. If the corresponding terminal is electrically connected to the charging terminal (not shown) of the lower combining part 160, the second vacuum cleaner 300 may be charged by supplying power to the second vacuum cleaner 300.

[0156] Reference Figure 1 and Figure 7 , the description of the vacuum cleaner base station 100 of the present invention is as follows.

[0157] The vacuum cleaner base station 100 may be provided with a first vacuum cleaner 200 and a second vacuum cleaner 300. The first vacuum cleaner 200 may be combined with the side of the vacuum cleaner base station 100. Specifically, the main body of the first vacuum cleaner 200 may be combined with the side of the vacuum cleaner base station 100. The second vacuum cleaner 300 may be combined with the lower part of the vacuum cleaner base station 100. The vacuum cleaner base station 100 may remove dust from the dust bucket 220 of the first vacuum cleaner 200. The vacuum cleaner base station 100 may remove dust from the dust bucket 310 of the second vacuum cleaner 300.

[0158] 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 in a column shape including at least one outer wall surface. As an example, the cover 110 may be formed in a shape similar to a quadrangular prism.

[0159] The cover body 110 may be formed with a space in which the dust collecting part 170 storing dust therein and the dust suction module 190 generating a flow force to collect dust toward the dust collecting part 170 can be accommodated.

[0160] The cover body 110 may include a bottom surface 111 , an outer wall surface 112 , and an upper surface 113 .

[0161] The bottom surface 111 may support the lower side of the dust suction module 190 in the gravity direction. That is, the bottom surface 111 may support the lower side of the dust collecting motor 191 of the dust suction module 190.

[0162] At this time, the bottom surface 111 can be configured to face the ground. The bottom surface 111 can be configured parallel to the ground, and of course, it can also be configured to be inclined at a predetermined angle to the ground. Through this structure, it has the advantage of being able to stably support the dust collecting motor 191, and when combined with the first vacuum cleaner 200, it can also balance the overall weight.

[0163] On the other hand, a lower coupling portion 160 may be coupled to the lower side of the bottom surface 111. The second vacuum cleaner 300 may be coupled to the lower coupling portion 160. The lower coupling portion 160 may be provided with an inclined portion 161 to which the lower side of the second vacuum cleaner 300 may be coupled. The lower coupling portion 160 will be described later.

[0164] The outer wall surface 112 may refer to a surface formed along the gravity direction, or may refer to a surface connected to the bottom surface 111. For example, the outer wall surface 112 may refer to a surface vertically 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.

[0165] The outer wall surface 112 may include at least one surface. For example, the outer wall surface 112 may include a first outer wall surface 112a, a second outer wall surface 112b, a third outer wall surface 112c, and a fourth outer wall surface 112d.

[0166] At this time, in this embodiment, the first outer wall surface 112a can be configured on the front side of the vacuum cleaner base station 100. The front side can refer to the surface where the first vacuum cleaner 200 or the second vacuum cleaner 300 is combined. Therefore, the first outer wall surface 112a can form the appearance of the front side of the vacuum cleaner base station 100.

[0167] On the other hand, in order to understand the present embodiment, the direction is defined as follows: In the present embodiment, the direction may be defined in a state where the cleaner 200 is placed on the cleaner base station 100 .

[0168] When the first vacuum cleaner 200 is placed on the vacuum cleaner base station 100 , the direction in which the first vacuum cleaner 200 is exposed to the outside of the vacuum cleaner base station 100 may be referred to as the front.

[0169] From another perspective, the direction in which the suction motor 214 of the first vacuum cleaner 200 is arranged when the first vacuum cleaner 200 is placed on the vacuum cleaner base station 100 can be called the front. In addition, the direction opposite to the direction in which the suction motor 214 is arranged in the vacuum cleaner base station 100 can be called the rear.

[0170] Furthermore, the surface in the direction opposite to the front surface with respect to the internal space of the cover body 110 as a reference may be referred to as the back surface of the vacuum cleaner base station 100. Therefore, the back surface may refer to the direction in which the second outer wall surface 112b is formed.

[0171] Furthermore, the left side when observing the front side with the internal space of the cover body 110 as a reference may be referred to as the left side, and the right side may be referred to as the right side. Therefore, the left side may indicate the direction formed by the third outer wall surface 112c, and the right side may indicate the direction formed by the fourth outer wall surface 112d.

[0172] The first outer wall surface 112a may be formed in a planar shape, or may be formed in a curved shape as a whole, or may be formed with a curved surface in part.

[0173] The first outer wall surface 112a may have an appearance corresponding to the shape of the first vacuum cleaner 200. In detail, a coupling portion 120 may be disposed on the first outer wall surface 112a. With this configuration, the first vacuum cleaner 200 may be coupled to the vacuum cleaner base station 100 and may be supported by the vacuum cleaner base station 100. The specific configuration of the coupling portion 120 will be described later.

[0174] On the other hand, a structure for placing various types of cleaning modules 260 used for the first cleaner 200 may be added to the first outer wall surface 112a.

[0175] In this embodiment, the second outer wall surface 112b may be a surface opposite to the first outer wall surface 112a. That is, the second outer wall surface 112b may be disposed on the back of the vacuum cleaner base station 100. The back side may be a surface opposite to the surface combined with the first 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.

[0176] As an example, the second outer wall surface 112 b may be formed in a flat surface. With such a configuration, the vacuum cleaner base station 100 can be closely attached to the indoor wall and stably supported.

[0177] As another example, a structure for placing various cleaning modules 260 used in the first cleaner 200 may be added to the second outer wall surface 112b.

[0178] In this embodiment, the third outer wall surface 112c and the fourth outer wall surface 112d may represent surfaces connecting the first outer wall surface 112a and the second outer wall surface 112b. In this case, the third outer wall surface 112c may be arranged on the left side of the vacuum cleaner base station 100, and the fourth outer wall surface 112d may be arranged on the right side of the vacuum cleaner base station 100. Alternatively, the third outer wall surface 112c may be arranged on the right side of the vacuum cleaner base station 100, and the fourth outer wall surface 112d may be arranged on the left side of the vacuum cleaner base station 100.

[0179] The third outer wall surface 112c or the fourth outer wall surface 112d is formed in a flat shape, but of course, it can be formed in a curved shape as a whole, and can be formed to include a curved surface in a part.

[0180] On the other hand, a structure for placing various types of cleaning modules 260 used for the first cleaner 200 may be added to the third outer wall surface 112c or the fourth outer wall surface 112d.

[0181] The upper surface 113 may form the upper appearance of the vacuum cleaner base station. That is, the upper surface 113 may indicate the surface of the vacuum cleaner base station that is disposed at the uppermost side in the gravity direction and exposed to the outside.

[0182] For reference, in the present embodiment, the upper side and the lower side may respectively represent the upper side and the lower side along the gravity direction (the direction perpendicular to the ground) in a state where the cleaner base station 100 is set on the ground.

[0183] At this time, the upper surface 113 may be arranged parallel to the ground, or may be arranged to be inclined at a predetermined angle to the ground.

[0184] The display unit 410 may be disposed on the upper surface 113. As an example, the display unit 410 may display the status of the vacuum cleaner base station 100, the status of the first vacuum cleaner 200, and the status of the second vacuum cleaner 300, and may also display information such as the cleaning progress status and a map of the cleaning area.

[0185] On the other hand, according to an embodiment, the upper surface 113 may be detachably provided on the outer wall surface 112. At this time, if the upper surface 113 is separated, the battery separated from the vacuum cleaner 200 may be accommodated in the inner space surrounded by the outer wall surface 112, and a terminal (not shown) capable of charging the separated battery may be provided.

[0186] Figure 8 A diagram showing a joint portion in a vacuum cleaner base station for explaining an embodiment of the present invention is shown. Fig. 9 A diagram for explaining the configuration of a coupling portion and a fixing unit in a vacuum cleaner base station according to an embodiment of the present invention is shown.

[0187] Reference Figure 8 and Fig. 9, the coupling part 120 of the vacuum cleaner base station 100 of the present invention is described as follows.

[0188] The vacuum cleaner base station 100 may include a coupling portion 120 for coupling with the first vacuum cleaner 200. Specifically, the coupling portion 120 may be disposed on the first outer wall surface 112a, and may be coupled with the main body 210, the dust barrel 220 and the battery cover 230 of the first vacuum cleaner 200.

[0189] The coupling portion 120 may include a coupling surface 121. The coupling surface 121 may be disposed on a side surface of the cover body 110. As an example, the coupling surface 121 may represent a groove-shaped surface that is recessed from the first outer wall surface 112a toward the inner side of the vacuum cleaner base station 100. That is, the coupling surface 121 may represent a surface that forms a step with the first outer wall surface 112a.

[0190] The first vacuum cleaner 200 can be combined with the combination surface 121. As an example, the combination surface 121 can be configured to face the lower side of the dust bucket 220 and the battery cover 230 of the first vacuum cleaner 200. Here, the lower side can refer to the side facing the ground when the user uses the first vacuum cleaner 200 or places the first vacuum cleaner 200 on the ground.

[0191] As an example, the angle formed by the coupling surface 121 and the ground may be a right angle. Thus, when the first vacuum cleaner 200 is coupled to the coupling surface 121, the space of the vacuum cleaner base station 100 can be minimized.

[0192] As another example, the coupling surface 121 may be inclined at a predetermined angle to the ground. Thus, when the first vacuum cleaner 200 is coupled to the coupling surface 121 , the vacuum cleaner base station 100 may be stably supported.

[0193] The joint surface 121 may be formed with a dust hole 121a to allow air outside the housing 110 to flow into the interior. The dust hole 121a may be formed in a hole shape corresponding to the shape of the dust barrel 220 so that dust in the dust barrel 220 flows into the dust collecting portion 170. The dust hole 121a may be formed in a shape corresponding to the discharge cover 222 of the dust barrel 220.

[0194] The dust through hole 121a may be formed to communicate with the first cleaner flow path 181 described later. In addition, the dust through hole 121a may be formed to communicate with the inner space of the dust container 220 when the first cleaner 200 is combined with the cleaner base station 100 and the discharge cover 222 is opened.

[0195] On the other hand, on the dust hole 121a, the door 141 can rotate. The door 141 can be a rotating body that is hingedly coupled to the cover body 110 to rotate. Therefore, as the door 141 rotates, the dust hole 121a can be selectively opened and closed. In addition, in a state where the first vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the discharge cover 222 can rotate on the dust hole 121a. In a state where the first vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the discharge cover 222 can rotate together with the rotation of the door 141. Therefore, as the discharge cover 222 rotates, the dust hole 121a can be selectively opened and closed.

[0196] The coupling portion 120 may include a dust bin guide surface 122. The dust bin guide surface 122 may be disposed on the first outer wall surface 112a. The dust bin guide surface 122 may be connected to the first outer wall surface 112a. In addition, the dust bin guide surface 122 may be connected to the coupling surface 121.

[0197] The dust bucket guide surface 122 may be formed in a shape corresponding to the outer side of the dust bucket 220. The dust bucket guide surface 122 may be combined with the front outer side of the dust bucket 220. Thus, the dust bucket guide surface 122 may be combined with the dust bucket 220 of the first cleaner to support the dust bucket 220.

[0198] The coupling portion 120 may include a guide protrusion 123. The guide protrusion 123 may be configured on the coupling surface 121. The guide protrusion 123 may protrude from the coupling surface 121. Two guide protrusions 123 may be configured to be spaced apart from each other. The distance between the two spaced apart guide protrusions 123 may correspond to the width of the battery cover 230 of the first vacuum cleaner 200. Thus, the guide protrusion 123 may guide the coupling direction of the first vacuum cleaner 200. In addition, the battery cover 230 and the battery 240 of the first vacuum cleaner 200 may be accommodated between a pair of guide protrusions 123.

[0199] The coupling portion 120 may include a side wall 124. The side wall 124 may refer to a wall surface disposed on both sides of the coupling surface 121, and may be vertically connected to the coupling surface 121. The side wall 124 may be connected to the first outer wall surface 112a. In addition, the side wall 124 may be connected to the dust bin guide surface 122, that is, the side wall 124 forms a surface connected to the dust bin guide surface 122. Thus, the first vacuum cleaner 200 can be stably accommodated.

[0200] The coupling portion 120 may include a coupling sensor 125. The coupling sensor 125 may sense whether the first cleaner 200 is coupled to the coupling portion 120.

[0201] The combined sensor 125 may also include a contact sensor. As an example, the combined sensor 125 may include a micro switch (see Fig.16 ). At this time, the combined sensor 125 can be configured on the guide protrusion 123. Therefore, if the battery cover 230 or the battery 240 of the first vacuum cleaner 200 is combined between a pair of guide protrusions 123, it will contact the combined sensor 125, and the combined sensor 125 can sense that the first vacuum cleaner 200 is combined.

[0202] On the other hand, the combined sensor 125 may also include a non-contact sensor. As an example, the combined sensor 125 may include an infrared sensor unit (IR sensor). In this case, the combined sensor 125 may be configured on the side wall 124. Therefore, if the dust bin 220 or the main body 210 of the first vacuum cleaner 200 reaches the combined surface 121 via the side wall 124, the combined sensor 125 may sense the existence of the dust bin 220 or the main body 210.

[0203] The combined sensor 125 may be opposite to the dust container 220 or the battery cover 230 of the first cleaner 200 .

[0204] The coupling sensor 125 may be a device that determines whether power is applied to the battery 240 of the first cleaner 200 and determines whether the first cleaner 200 is coupled.

[0205] The combination part 120 may include a suction part guide surface 126. The suction part guide surface 126 may be arranged on the first outer wall surface 112a. The suction part guide surface 126 may be connected to the dust bin guide surface 122. The suction part 212 may be combined with the suction part guide surface 126. The shape of the suction part guide surface 126 may be formed into a shape corresponding to the shape of the suction part 212. Thus, it is possible to provide convenience for the main body 210 of the first vacuum cleaner 200 to be combined with the combination surface 121.

[0206] The coupling portion 120 may include a fixing member access hole 127. The fixing member access hole 127 may be formed in the form of a long hole along the side wall 124 to allow the fixing member 131 to enter and exit. As an example, the fixing member access hole 127 may be a rectangular hole formed along the side wall 124. The fixing member 131 will be described in detail later.

[0207] With this configuration, when the user couples the first vacuum cleaner 200 to the coupling portion 120 of the vacuum cleaner base station 100, the main body 210 of the first vacuum cleaner 200 can be stably arranged on the coupling portion 120 due to the dust bucket guide surface 122, the guide protrusion 123, and the suction portion guide surface 126. Thus, the convenience of coupling the dust bucket 220 and the battery cover 230 of the first vacuum cleaner 200 to the coupling surface 121 can be provided.

[0208] Reference Fig. 9 , the fixing unit 130 of the present invention is described as follows.

[0209] The vacuum cleaner base station 100 of the present invention may include a fixing unit 130. The fixing unit 130 may be disposed on the side wall 124 of the joint portion. In addition, at least a portion of the fixing unit 130 may be disposed inside the joint surface 121. The fixing unit 130 may fix the vacuum cleaner 200 coupled to the joint surface 121. Specifically, the fixing unit 130 may fix the dust bucket 220 and the battery cover 230 of the vacuum cleaner 200 coupled to the joint surface 121.

[0210] The fixing unit 130 may include a fixing member 131 for fixing the dust bucket 220 and the battery cover 230 of the vacuum cleaner 200, and a fixing motor 133 for driving the fixing member 131. In addition, the fixing unit 130 may further include a fixing connecting rod 135 for transmitting the power of the fixing motor 133 to the fixing member 131.

[0211] The fixing member 131 may be disposed on the side wall 124 of the coupling portion 120 , and may be reciprocatably disposed on the coupling portion side wall 124 to fix the dust barrel 220 . Specifically, the fixing member 131 may be accommodated inside the fixing member access hole 127 .

[0212] The fixing members 131 may be respectively disposed on both sides of the coupling portion 120. As an example, two fixing members 131 may be symmetrically disposed in pairs with the coupling surface 121 as the center.

[0213] The fixing part motor 133 can provide power to move the fixing member 131 (see Fig.16 ).

[0214] The fixing part link 135 may convert the rotation force of the fixing part motor 133 into the reciprocating movement of the fixing member 131 .

[0215] The fixed seal 136 may be disposed on the dust bucket guide surface 122 to airtightly seal the dust bucket 220 when the dust cleaner 200 is combined. With this configuration, if the dust bucket 220 of the dust cleaner 200 is combined, the fixed seal 136 may be pressed by the weight of the dust cleaner 200, and the dust bucket 220 and the dust bucket guide surface 122 may be sealed.

[0216] The fixed seal 136 may be disposed on a virtual extension line of the fixed member 131. With this configuration, if the fixed portion motor 133 is operated and the fixed member 131 presses the dust bin 220, the outer circumference of the dust bin 220 at the same height may be sealed.

[0217] According to an embodiment, the fixed seal 136 may be disposed on the dust container guide surface 122 in a bent line form corresponding to the configuration of the cover opening unit 150 described later.

[0218] Therefore, when the main body 210 of the vacuum cleaner 200 is arranged on the coupling part 120, the fixing unit 130 can fix the main body 210 of the vacuum cleaner 200. Specifically, when the coupling sensor 125 senses that the main body 210 of the vacuum cleaner 200 is coupled to the coupling part 120 of the vacuum cleaner base station 100, the fixing part motor 133 can fix the main body 210 of the vacuum cleaner 200 by moving the fixing member 131.

[0219] Thus, the suction force of the vacuum cleaner can be improved by preventing the remaining dust from remaining in the dust bin. Further, the remaining dust can be prevented from remaining in the dust bin to remove the odor generated by the remaining dust.

[0220] Fig.10 and Fig.11 A diagram for explaining the operation of opening and closing the door of the door unit in the vacuum cleaner base station according to the embodiment of the present invention is shown.

[0221] Reference Figures 7 to 11 , the door unit 140 of the present invention is described as follows.

[0222] The vacuum cleaner base station 100 of the present invention may include a door unit 140. The door unit 140 may be configured to be able to open and close the dust through hole 121a.

[0223] The door unit 140 may include a door 141 , a door motor 142 , and a door arm 143 .

[0224] The door 141 may be hingedly coupled to the coupling surface 121, and may selectively open and close the dust through hole 121a. The door 141 may include a door body 141a.

[0225] The door body 141a may be formed in a shape capable of blocking the dust through hole 121a. As an example, the door body 141a may be formed in a shape similar to a circular plate.

[0226] Based on the state in which the door body 141a blocks the dust through hole 121a, a hinge portion may be disposed on the upper side of the door body 141a, and an arm coupling portion 141b may be disposed on the lower side of the door body 141a.

[0227] The door body 141a can be formed into a shape that can make the dust hole 121a airtight. As an example, the outer side surface of the door body 141a exposed to the outside of the vacuum cleaner base station 100 is formed to have a diameter corresponding to the diameter of the dust hole 121a, and the inner side surface arranged inside the vacuum cleaner base station 100 is formed to have a diameter larger than the diameter of the dust hole 121a. In addition, a step can be generated between the outer side surface and the inner side surface. On the other hand, at least one reinforcing rib can be protrudingly formed on the inner side surface of the door body 141a, and the reinforcing rib connects the hinge part and the arm joint 141b to strengthen the support force of the door body 141a.

[0228] The hinge part may be a means for hinge-joining the door 141 to the joint surface 121. The hinge part may be disposed at an upper end portion of the door body 141a and joined to the joint surface 121.

[0229] The arm coupling part 141b may be a means for rotatably coupling the door arm 143. The arm coupling part 141b may be disposed at the lower side of the door body 141a, rotatably coupled to the door body 141a, and rotatably coupled to the door arm 143.

[0230] With this configuration, when the door 141 closes the dust hole 121a, if the door arm 143 pulls the door body 141a, the door body 141a rotates toward the inside of the vacuum cleaner base station 100 with the hinge as the axis, and the dust hole 121a can be opened. On the other hand, when the dust hole 121a is open, if the door arm 143 pushes the door body 141a, the door body 141a rotates toward the outside of the vacuum cleaner base station 100 with the hinge as the axis, and the dust hole 121a can be blocked.

[0231] On the other hand, when the cleaner 200 is combined with the cleaner base station 100 and the discharge cover 222 is separated from the dust bucket body 210, the door 141 may contact the discharge cover 222. And, as the door 141 rotates, the discharge cover 222 may rotate in conjunction with the door 141.

[0232] The door motor 142 may provide power to rotate the door 141. Specifically, the door motor 142 may rotate the door arm 143 in a forward direction or a reverse direction. Here, the forward direction may refer to the direction in which the door arm 143 pulls the door 141. Therefore, if the door arm 143 rotates in the forward direction, the dust hole 121a may be opened. In addition, the reverse direction may refer to the direction in which the door arm 143 pushes the door 141. Therefore, if the door arm 143 rotates in the reverse direction, at least a portion of the dust hole 121a may be closed. The forward direction may be the opposite direction to the reverse direction.

[0233] The door arm 143 may connect the door 141 and the door motor 142 , and may open and close the door 141 using power generated by the door motor 142 .

[0234] As an example, the door arm 143 may include a first door arm 143a and a second door arm 143b. One end of the first door arm 143a may be combined with the door motor 142. The first door arm 143a may be rotated by the power of the door motor 142. The other end of the first door arm 143a may be rotatably combined with the second door arm 143b. The first door arm 143a may transmit the force transmitted from the door motor 142 to the second door arm 143b. One end of the second door arm 143b may be combined with the first door arm 143a. The other end of the second door arm 143b may be combined with the door 141. The second door arm 143b may open and close the dust through hole 121a by pushing or pulling the door 141.

[0235] The door unit 140 may further include a door opening and closing sensor 144. The door opening and closing sensor 144 may be disposed inside the housing 100 and may sense whether the door 141 is in an open state (see Fig.16 ).

[0236] As an example, the door opening and closing sensors 144 may be disposed at both ends of the rotational movement region of the door arm 143. As another example, the door opening and closing sensors 144 may be disposed at both ends of the movement region of the door 141.

[0237] Therefore, if the door arm 143 moves to the preset door opening position DP1 or the door 141 opens to a specified position, the door opening and closing sensing unit 144 can sense that the door has been opened. In addition, if the door arm 143 moves to the preset door closing position DP2 or the door 141 opens to a specified position, the door opening and closing sensing unit 144 can sense that the door has been opened.

[0238] The door opening / closing sensor 144 may include a contact sensor. As an example, the door opening / closing sensor 144 may include a micro switch.

[0239] On the other hand, the door opening / closing sensor 144 may include a non-contact sensor. For example, the door opening / closing sensor 144 may include an infrared sensor (IR sensor).

[0240] With this configuration, the door unit 140 can allow the outside of the first outer wall surface 112 a to communicate with the flow path portion 180 and / or the dust collecting portion 170 by selectively opening and closing at least a portion of the joint surface 121 .

[0241] The door unit 140 may be opened together when the discharge cover 222 of the cleaner 200 is opened. In addition, if the door unit 140 is closed, the discharge cover 222 of the cleaner 200 may be closed together in conjunction therewith.

[0242] When the dust of the dust bucket 220 of the cleaner 200 is removed, the door motor 142 can couple the discharge cover 222 to the dust bucket body 221 by rotating the door 141. Specifically, the door motor 142 can rotate the door 141 by rotating the door 141, and the rotating door 141 can push the discharge cover 222 toward the dust bucket body 221.

[0243] Reference Figures 7 to 12 , the cover opening unit 150 of the present invention is described as follows.

[0244] The vacuum cleaner base station 100 of the present invention may include a cover opening unit 150. The cover opening unit 150 may be disposed at the coupling portion 120, and may open the discharge cover 222 of the vacuum cleaner 200.

[0245] The cover opening unit 150 may include a push protrusion 151 , a cover opening motor 152 , a cover opening gear 153 , a support plate 154 , and a gear box 155 .

[0246] The push protrusion 151 may move to press the coupling rod 222 c when the cleaner 200 is coupled.

[0247] The push protrusion 151 may be disposed on the dust barrel guide surface 122. Specifically, a protrusion moving hole may be formed on the dust barrel guide surface 122, and the push protrusion 151 may be exposed to the outside through the protrusion moving hole.

[0248] The push protrusion 151 can be arranged at a position that can press the coupling rod 222c when the first vacuum cleaner 200 is combined. That is, the coupling rod 222c can be arranged on the protrusion moving hole. In addition, the coupling rod 222c can be arranged on the moving area of ​​the push protrusion 151.

[0249] The push protrusion 151 can reciprocate linearly to press the coupling rod 222c. Specifically, the push protrusion 151 can be coupled to the gear box 155 and guided to move linearly. The push protrusion 151 can be coupled to the cover opening gear 153 and can move together with the movement of the cover opening gear 153.

[0250] The cover opening motor 152 can provide power to move the push protrusion 151. Specifically, the cover opening motor 152 can rotate the motor shaft (not shown) in a forward direction or a reverse direction. Here, the forward direction can refer to the direction in which the push protrusion 151 presses the coupling rod 222c. In addition, the reverse direction can refer to the direction in which the push protrusion 151 pressing the coupling rod 222c is reset to the original position. The forward direction can be the opposite direction to the reverse direction.

[0251] The cover opening gear 153 is combined with the cover opening motor 152, and the power of the cover opening motor 152 can be used to move the push protrusion 151. Specifically, the cover opening gear 153 can be accommodated in the gear box 155. The driving gear 153a of the cover opening gear 153 can be combined with the motor shaft of the cover opening motor 152 to receive power. The driven gear 153b of the cover opening gear 153 can be combined with the push protrusion 151 to move the push protrusion 151. As an example, the driven gear 153b can be set in a rack shape, meshed with the driving gear 153a, and receive power from the driving gear 153a.

[0252] At this time, a torsion spring 222d may be provided on the discharge cover 222. Due to the elastic force of the torsion spring 222d, the discharge cover 222 can be rotated more than a predetermined angle and can be supported at the rotated position. Therefore, the discharge cover 222 can be opened to connect the dust through hole 121a with the interior of the dust bin 220.

[0253] The gear box 155 may be disposed inside the housing 110 , and arranged on the lower side of the coupling portion 120 in the direction of gravity, and accommodate the cover opening gear 153 therein.

[0254] The gear box 155 may be provided with a cover opening sensor 155f. In this case, the cover opening sensor 155f may also include a contact sensor. As an example, the cover opening sensor 155f may include a micro switch. On the other hand, the cover opening sensor 155f may also include a non-contact sensor. As an example, the cover opening sensor 155f may include an infrared sensor.

[0255] The cover opening sensor 155f may be disposed on at least one of the inner side surface and the outer side surface of the gear box 155. As an example, one cover opening sensor 155f may be disposed on the inner side surface of the gear box 155. At this time, the cover opening sensor 155f may sense that the push protrusion 151 is in the initial position.

[0256] As another example, two cover opening sensors 155f may be disposed on the outer side surface of the gear case 155. In this case, the cover opening sensors 155f may sense the initial position of the push protrusion 151 and the cover opening position.

[0257] Therefore, according to the present invention, the user can open the dust container 220 by using the cover opening unit 150 without separately opening the discharge cover 222 of the first cleaner, thereby improving convenience.

[0258] In addition, when the vacuum cleaner 200 is coupled to the vacuum cleaner base station 100 , the discharge cover 222 is opened, thereby having an effect of preventing dust from scattering.

[0259] Reference Figure 7 The vacuum cleaner base station 100 of the embodiment of the present invention includes a lower coupling portion 160. The vacuum cleaners 200 and 300 can be coupled to the lower coupling portion 160. Specifically, the second vacuum cleaner 300 can be coupled to the lower coupling portion 160. When the second vacuum cleaner 300 is coupled to the lower coupling portion 160, dust stored inside the second vacuum cleaner 300 can be collected by the vacuum cleaner base station 100.

[0260] The lower coupling portion 160 may include an inclined portion 161 for the second cleaner 300 to climb for coupling. The inclined portion 161 may be composed of a plurality of inclined surfaces having different inclinations, and each of the plurality of inclined surfaces may determine its own inclination degree according to the shape of the bottom portion of the second cleaner 300.

[0261] The lower joint 160 may include a dust suction hole 162, which is disposed at a position corresponding to the position where the dust bucket 310 of the second vacuum cleaner 300 is disposed, based on the state of being combined with the second vacuum cleaner 300. More specifically, the dust suction hole 162 may be formed on the side wall of the lower joint 160. At this time, the side wall may be formed in a direction perpendicular to the ground, and may be configured to face the dust bucket 310 of the second vacuum cleaner 300. Therefore, the dust suction hole 162 may be configured at a position facing the dust discharge hole 320 based on the state of being combined with the second vacuum cleaner 300. For example, the dust suction hole 162 may be configured at a position farther from the ground than the inclined portion 161.

[0262] The dust suction hole 162 may be formed in a shape corresponding to the dust discharge hole 320. As an example, the dust suction hole 162 may be in a quadrangular hole shape. In this case, the dust suction hole 162 may accommodate at least a portion of the second vacuum cleaner discharge cover 330 when the second vacuum cleaner discharge cover 330 is open. With the above configuration, even if the dust collecting motor 191 is running and the second vacuum cleaner discharge cover 330 is open, the dust discharge hole 320 and the dust suction hole 162 may be arranged adjacent to each other and communicate with each other.

[0263] In addition, the lower combining part 160 may include a charging terminal (not shown), which is electrically connected to the second vacuum cleaner 300 to supply power to charge the second vacuum cleaner 300. If the second vacuum cleaner 300 is combined, the corresponding terminal of the second vacuum cleaner 300 may be electrically connected to the charging terminal (not shown) of the lower combining part 160, and the second vacuum cleaner 300 may be charged by supplying power from the lower combining part 160 to the second vacuum cleaner 300.

[0264] On the other hand, a second cleaner flow path 182 may be formed at the lower coupling portion 160. The second cleaner flow path 182 may be formed to communicate with the dust suction hole 162.

[0265] On the other hand, refer to Figure 7 and Fig.16 , the dust collecting section 170 is described as follows.

[0266] The vacuum cleaner base station 100 may include a dust collecting unit 170. The dust collecting unit 170 may be disposed inside the cover body 110. The dust collecting unit 170 may be disposed on the lower side of the coupling unit 120 in the direction of gravity.

[0267] As an example, the dust collecting unit 170 may represent a dust bag that collects dust sucked from the inside of the dust container 220 of the cleaner 200 by the dust collecting motor 191 .

[0268] The dust collecting portion 170 may be detachably coupled to the cover body 110 .

[0269] Therefore, the dust collecting part 170 may be separated from the cover body 110 and discarded, and a new dust collecting part 170 may be combined with the cover body 110. That is, the dust collecting part 170 may be defined as a consumable part.

[0270] The dust bag may be configured to increase in volume and contain dust inside when suction is generated by the dust collecting motor 191 .

[0271] For this purpose, the dust bag can be made of a material through which air can pass but foreign matter such as dust cannot pass. As an example, the dust bag can be made of a non-woven fabric material and can have a hexahedral shape based on the increased volume.

[0272] Therefore, the user does not need to separately bundle a bag or the like for collecting dust, and thus user convenience can be improved.

[0273] Different from this, the dust bag can be formed of a non-permeable material. For example, the dust bag can include a rolled plastic (not shown). In this case, the dust bag can be joined by a joining mechanism (not shown). Through the above configuration, if the dust bag is sealed or joined, it is possible to prevent the dust or odor trapped inside the dust bag from leaking to the outside of the dust bag. In this case, the dust bag can be installed on the cover body 110 through a dust bag box (not shown). The dust bag can be replaced by the dust bag box as needed.

[0274] On the other hand, the vacuum cleaner base station 100 according to the embodiment of the present invention may further include a sterilization module (not shown).

[0275] A sterilization module (not shown) may be disposed on the flow path portion 180 , or at least one sterilization module (not shown) may be disposed around the dust collecting portion 170 .

[0276] The sterilization module (not shown) is configured to sterilize the dust collected in the dust collecting part 170. The sterilization module (not shown) may include a light source for irradiating sterilization light and a protection panel disposed under the light source to protect the light source.

[0277] Here, the light source may include at least one light emitting diode (LED) that can emit sterilizing light with sterilizing power capable of removing bacteria. The sterilizing light irradiated by the light source may have different wavelengths depending on the type of the light emitting diode.

[0278] As one example, the light source may be a light emitting diode that emits ultraviolet light having a wavelength in the UV-C range, or as another example, the light source may be a light emitting diode that emits visible light having a wavelength of 405 nm.

[0279] In order to prevent the light source from being damaged, the protection panel can be arranged at a predetermined distance from the light source below the light source. In this case, the protection panel can be set by a material with the highest transmittance of the light source. As an example, the protection panel can be made of quartz.

[0280] The vacuum cleaner base station 100 of the embodiment of the present invention has a sterilization module (not shown) for sterilization, so that bacteria cannot reproduce in the dust collecting part 170 , thereby enabling hygienic management of the dust collecting part 170 that stores the sucked dust for a long time.

[0281] Fig.13 A diagram showing a flow path conversion module in a flow path portion of a vacuum cleaner base station for illustrating an embodiment of the present invention is shown. Fig.14 A diagram for explaining the configuration relationship between the first vacuum cleaner flow path and the dust collection flow path in the flow path portion of the vacuum cleaner base station according to an embodiment of the present invention is shown. Fig.15 A diagram for explaining the arrangement relationship between the second cleaner flow path and the dust collection flow path in the flow path portion of the cleaner base station according to an embodiment of the present invention is shown.

[0282] Reference Figures 7 to 15 The flow path portion 180 of the vacuum cleaner base station according to an embodiment of the present invention is described as follows.

[0283] The cleaner base station 100 may include a flow path unit 180. The flow path unit 180 may connect the dust bins 220 and 310 of the cleaners 200 and 300 to the dust collecting unit 170. That is, the flow path unit 180 may connect the dust bin 220 of the first cleaner 200 or the dust bin 310 of the second cleaner 300 to the dust collecting unit 170.

[0284] The flow path portion 180 may include a first cleaner flow path 181 , a second cleaner flow path 182 , a flow path conversion module 183 , and a dust collection flow path 184 .

[0285] The first cleaner flow path 181 is disposed inside the housing 110 and is flow-connected to the dust container 220 of the first cleaner 200 .

[0286] The first cleaner flow path 181 may connect the dust container 220 of the first cleaner 200 and the dust collecting part 170. The first cleaner flow path 181 may be disposed at the rear side of the coupling part 120. The first cleaner flow path 181 may indicate a space between the dust container 220 of the first cleaner 200 and the dust collecting part 170.

[0287] The first cleaner flow path 181 may be formed in a shape extending rearward from the coupling portion 120 and extending downward after being bent.

[0288] Specifically, the first cleaner flow path 181 includes a first flow path 181 a. The first flow path 181 a may be communicated with the dust through hole 121 a, and may be formed behind the coupling portion 120 along the front-rear direction of the cleaner base station 100.

[0289] In a state where the first cleaner 200 is coupled to the cleaner base station 100 and the door 141 and the discharge cover 222 are opened, the space inside the dust container 220, the dust through hole 121a, and the first flow path 181a may be communicated with each other.

[0290] As the first flow path 181 a is formed along the front-rear direction of the cleaner base station 100 , sufficient space can be provided for the air and foreign matter inside the dust container 220 to flow into the inside of the cleaner base station 100 when the dust collecting motor 191 is running.

[0291] In addition, the first cleaner flow path 181 includes a second flow path 181 b. The second flow path 181 b may communicate with the first flow path 181 a and may be formed along the up-down direction of the cleaner base station 100.

[0292] In this case, the length of the second flow path 181b in the vertical direction may be greater than the length of the first flow path 181a in the front-rear direction. With the above configuration, the flow path loss can be minimized.

[0293] The diameter of the upper side of the second flow path 181b may be greater than the diameter of the lower side. That is, the second flow path 181b may be formed in a shape in which the diameter decreases from the upper side to the lower side. The above configuration has the following effects: the air and foreign matter flowing into the dust bin 220 can be collected and sucked into the dust collecting part 170, and the flow velocity increases as it approaches the lower part of the second flow path 181b, thereby increasing the suction force.

[0294] On the other hand, in the vacuum cleaner base station 100 according to the embodiment of the present invention, the second flow path 181b can be formed perpendicular to the ground, or form a specified angle with the ground.

[0295] Specifically, in this embodiment, a virtual line penetrating the inside of the second flow path 181b may be formed. That is, the vacuum cleaner base station 100 of the present invention may include a virtual first vacuum cleaner flow path penetrating line P1 penetrating the second flow path 181b along the length direction.

[0296] The first cleaner flow path penetration line P1 may be formed along the length direction (axial direction) of the second flow path 181b, and may be formed to penetrate the interior of the second flow path 181b.

[0297] On the other hand, the lower portion of the first cleaner flow path 181 may be connected to the flow path conversion module 183. Specifically, the lower portion of the first cleaner flow path 181 may be connected to the connection hose 1832 provided in the flow path conversion module 183. That is, the lower portion of the first cleaner flow path 181 may be connected to the flow path (hereinafter referred to as "connection flow path") formed inside the connection hose 1832.

[0298] According to the above configuration, the dust in the dust container 220 of the first cleaner 200 can be moved to the dust collecting portion 170 through the first cleaner flow path 181 via the connecting flow path and the dust collecting flow path 184 .

[0299] The second cleaner flow path 182 is disposed inside the housing 110 and is connected to the dust container 310 of the second cleaner 300 .

[0300] The second cleaner flow path 182 may connect the dust container 310 of the second cleaner 300 and the dust collecting portion 170 .

[0301] The second cleaner flow path 182 may be formed rearward from the lower coupling portion 160 and then bent upward.

[0302] Specifically, the second cleaner flow path 182 includes a third flow path 182a. The third flow path 182a can be connected to the dust suction hole 162 and formed from the dust suction hole 162 to the rear along the front-to-back direction of the cleaner base station 100. For example, the third flow path 182a can be formed from the dust suction hole 162 to the rear in a direction parallel to the ground.

[0303] The space inside the dust bucket 310 of the second vacuum cleaner 300 and the dust suction hole 162 and the third flow path 182a may be connected to each other. That is, if the dust collecting motor 191 is running, the second vacuum cleaner discharge cover 330 may be opened under the suction force of the dust collecting motor 191. At this time, the space inside the dust bucket 310 of the second vacuum cleaner 300 and the dust suction hole 162 and the third flow path 182a may be connected to each other, and the dust stored inside the dust bucket 310 may pass through the dust suction hole 162 and the third flow path 182a.

[0304] In addition, the second cleaner flow path 182 includes a fourth flow path 182b. The fourth flow path 182b may be connected to the third flow path 182a and may be formed along the up-down direction of the cleaner base station 100. That is, the fourth flow path 182b may be bent upward from the third flow path 182a and may be formed in a direction perpendicular to the ground. If the dust collecting motor 191 is running, the dust stored in the dust barrel 310 may overcome gravity and flow upward under the suction force of the dust collecting motor 191.

[0305] In addition, the second cleaner flow path 182 includes a fifth flow path 182c. The fifth flow path 182c can communicate with the fourth flow path 182b and is formed to form a predetermined angle with the ground.

[0306] The fifth flow path 182 c may be disposed between the first flow path 181 a and the dust collecting flow path 184 .

[0307] As the fifth flow path 182c is configured to be farther from the ground than the dust collecting flow path 184, it is possible to prevent foreign matter (dust) flowing into the dust collecting flow path 184 from flowing back to the second cleaner flow path 181. At the same time, as the fifth flow path 182c is configured to be closer to the ground than the first flow path 181a, it has the effect of minimizing the distance that the foreign matter in the dust bucket 310 of the second cleaner 300 overcomes the gravity and flows upward by the operation of the dust collecting motor 191.

[0308] The fifth flow path 182c may refer to a flow path formed in a shape bent at a predetermined angle from the fourth flow path 182b.

[0309] One end of the fifth flow path 182 c in the axial direction is connected to the fourth flow path 182 b . In addition, the other end of the fifth flow path 182 c in the axial direction may be connected to a connection hose 1832 provided in the flow path conversion module 183 .

[0310] At this time, at least a portion of one end of the fifth flow path 182c may be arranged at a higher position than the other end. According to the above configuration, air and foreign matter passing through the fourth flow path 182b may move to the dust collection flow path 184 under the action of gravity.

[0311] On the other hand, in this embodiment, a virtual line penetrating the inside of the fifth flow path 182c may be formed. That is, the vacuum cleaner base station 100 of the present invention may include a virtual second vacuum cleaner flow path penetrating line P2 penetrating the fifth flow path 182c in the length direction.

[0312] The second cleaner flow path penetration line P2 is formed along the longitudinal direction (axial direction) of the fifth flow path 182c, and is formed to penetrate the interior of the fifth flow path 182c.

[0313] On the other hand, the diameter of the fourth flow path 182b may be smaller than the diameter of the fifth flow path 182c. At this time, the flow rate of the air and foreign matter flowing in the fourth flow path 182b may be faster than the flow rate of the air and foreign matter flowing in the fifth flow path 182c. Therefore, the dust stored in the dust bucket 310 of the second vacuum cleaner 300 may flow upward along the fourth flow path 182b against gravity and then flow downward along the fifth flow path 182c.

[0314] According to the above configuration, the second cleaner flow path 182 can collect dust stored in the second cleaner 300 disposed at a position closer to the ground than the dust collecting unit 170 .

[0315] The fifth flow path 182 c may communicate with the fourth flow path 182 b and the dust collection flow path 184 .

[0316] On the other hand, the lower portion of the fifth flow path 182c may be connected to the flow path conversion module 183. Specifically, the lower portion of the fifth flow path 182c may be communicated with the connection hose 1832 provided in the flow path conversion module 183. That is, the lower portion of the fifth flow path 181 may be communicated with the flow path (connection flow path) formed inside the connection hose 1832.

[0317] According to the above configuration, the dust in the dust container 310 of the second cleaner 300 can be moved to the dust collecting portion 170 through the second cleaner flow path 182 via the connecting flow path and the dust collecting flow path 184 .

[0318] The flow path switching module 183 is a component that selectively connects the dust collection flow path 184 to the first cleaner flow path 181 or the second cleaner flow path 182 .

[0319] The flow path conversion module 183 can selectively connect the dust collecting portion 170 disposed on the cover body 110 to the first cleaner flow path 181 or the second cleaner flow path 182 .

[0320] The flow path conversion module 183 may be disposed between the dust collecting unit 170 and the first cleaner flow path 181 and the second cleaner flow path 182. The flow path conversion module 183 may selectively open or close the first cleaner flow path 181 or the second cleaner flow path 182. Thus, it is possible to prevent a decrease in suction force due to the simultaneous opening of a plurality of flow paths 181 and 182.

[0321] For example, when the vacuum cleaner base station 100 is only combined with the first vacuum cleaner 200 , the flow path conversion module 183 can connect the first vacuum cleaner flow path 181 with the dust collecting part 170 , and can block the connection between the second vacuum cleaner flow path 182 and the dust collecting part 170 .

[0322] In addition, when the vacuum cleaner base station 100 is only combined with the second vacuum cleaner 300 , the flow path conversion module 183 can connect the second vacuum cleaner flow path 182 with the dust collecting part 170 , and can block the connection between the first vacuum cleaner flow path 181 and the dust collecting part 170 .

[0323] For ease of understanding, the direction of the flow path conversion module 183 is defined as follows. With the shell 1831 as the center, the direction in which the second cleaner flow path 182 is provided can be defined as the rear. With the shell 1831 as the center, the direction in which the driving cam 1836 is provided can be defined as the front. With the shell 1831 as the center, the direction in which the first cleaner flow path 181 is provided can be defined as the top. With the shell 1831 as the center, the direction in which the dust collecting section 170 is provided can be defined as the bottom.

[0324] The flow path conversion module 183 is disposed inside the housing 110 .

[0325] The flow path conversion module 183 includes a housing 1831 , a connecting hose 1832 , a first connecting rod 1833 , a second connecting rod 1834 , a conversion motor 1835 and a driving cam 1836 .

[0326] The flow path conversion module 183 includes a housing 1831. The housing 1831 forms an exterior and is a component that forms a frame for connecting or supporting other components.

[0327] The housing 1831 is formed in a barrel shape with a space provided therein, and has a first cleaner flow path connection portion 1831b connected to the first cleaner flow path 181 and a second cleaner flow path connection portion 1831c connected to the second cleaner flow path 182. In addition, the housing 1831 has a dust collection flow path connection portion 1831d connected to the dust collection flow path 184.

[0328] The inner circumference of the shell 1831 may form an arc. The inner circumference of the shell 1831 constitutes a part of a virtual circle centered on the central axis. Fig.11 , the central axis 1831a of the shell is arranged along the left-right direction of the vacuum cleaner base station 100.

[0329] The first cleaner flow path connection part 1831b may be formed to protrude radially outward from the housing 1831. The first cleaner flow path connection part 1831b may be formed to protrude upward. A flange may be formed at the end of the first cleaner flow path connection part 1831b, and as the flange is inserted into the groove formed in the first cleaner flow path 181, the first cleaner flow path connection part 1831b may be connected to the first cleaner flow path 181.

[0330] The second cleaner flow path connection part 1831c may be formed to protrude radially outward from the housing 1831. The second cleaner flow path connection part 1831c may be formed to protrude rearward from the housing 1831. A flange may be formed at the end of the second cleaner flow path connection part 1831c, and the second cleaner flow path connection part 1831c may be connected to the second cleaner flow path 182 as the flange is inserted into the groove formed in the second cleaner flow path 182.

[0331] The dust collecting flow path connection part 1831d may be formed to protrude radially outward from the housing 1831. The dust collecting flow path connection part 1831d may be formed to protrude downward. A flange may be formed at the end of the dust collecting flow path connection part 1831d, and as the flange is inserted into the groove formed in the dust collecting flow path 184, the dust collecting flow path connection part 1831d may be connected to the dust collecting flow path 184.

[0332] The housing 1831 may be detachably coupled to the housing 110. The housing 1831 is inserted into the housing 110, and is fixed as the flange formed on the first cleaner flow path connection part 1831b is inserted into the groove of the first cleaner flow path 181, the flange formed on the second cleaner flow path connection part 1831c is inserted into the groove of the second cleaner flow path 182, and the flange formed on the dust collection flow path connection part 1831d is inserted into the groove of the dust collection flow path 184. Thereafter, the housing 1831 may be threadedly coupled to the housing 110 using at least one screw.

[0333] The flow path conversion module 183 includes a connection hose 1832. The connection hose 1832 is a component that selectively connects the dust collection flow path 184 with the first cleaner flow path 181 or the second cleaner flow path 182.

[0334] As the inlet 1832a of the connection hose 1832 moves along the inner circumference of the housing 1831, the connection hose 1832 is selectively connected to either the first cleaner flow path connection portion 1831b or the second cleaner flow path connection portion 1831c. The outlet 1832b of the connection hose is connected to the dust collection flow path connection portion 1831d.

[0335] That is, the connecting hose 1832 can be arranged inside the flow path conversion module 183 , one end of the connecting hose 1832 can be connected to the first vacuum cleaner flow path 181 or the second vacuum cleaner flow path 182 , and the other end of the connecting hose 1832 can be connected to the dust collection flow path 184 .

[0336] The inlet 1832a of the connection hose 1832 may be arranged at a position higher than the outlet 1832b of the connection hose. That is, one end of the connection hose 1832 may be arranged farther from the ground than the other end of the connection hose 1832.

[0337] According to the above configuration, air and dust flowing in from the inlet 1832a of the connection hose 1832 can be accelerated by gravity and can flow out from the outlet 1832b of the connection hose 1832. Therefore, even if the connection hose 1832 is bent at a predetermined angle, flow path loss can be prevented.

[0338] The connection hose 1832 may be formed of a material having elasticity. For example, the connection hose 1832 may be made of rubber or resin material. Thus, the connection hose 1832 may be deformed in shape during movement.

[0339] Alternatively, a corrugation may be formed at least in a portion of the connection hose 1832. Thus, the connection hose 1832 may be structurally deformed.

[0340] The inlet 1832a of the connecting hose 1832 can be selectively connected to either the first cleaner flow path connection part 1831b or the second cleaner flow path connection part 1831c. The connecting hose 1832 can be connected to the first cleaner flow path connection part 1831b to connect the first cleaner flow path 181 to the dust collecting part 170. Alternatively, the connecting hose 1832 can be connected to the second cleaner flow path connection part 1831c to connect the second cleaner flow path 182 to the dust collecting part 170.

[0341] The inlet 1832a of the connection hose 1832 moves along the inner circumferential surface of the housing 1831. Specifically, the inlet 1832a of the connection hose 1832 can move along the inner circumferential surface of the housing 1831 while being spaced apart from the housing 1831 by a predetermined distance or more. Therefore, there is an effect that the seal 1832c disposed at the inlet 1832a of the connection hose 1832 is not damaged while the connection hose 1832 moves along the inner circumferential surface of the housing 1831.

[0342] The outlet 1832b of the connecting hose 1832 is connected to the dust collecting flow path connecting portion 1831d. The outlet 1832b of the connecting hose 1832 is fixedly connected to the dust collecting flow path connecting portion 1831d and is always connected to the dust collecting portion 170.

[0343] The flow path switching module 183 includes a first link 1833. The first link 1833 is a component that transmits the power of the motor to the connection hose 1832 to move the connection hose 1832.

[0344] One side of the first connecting rod 1833 is rotatably coupled to the housing 1831 , and the other side is coupled to the connecting hose 1832 .

[0345] The first link 1833 rotates around a rotation shaft 1833a disposed at one side. The first link 1833 is rotatably coupled to the housing 1831 via the rotation shaft 1833a of the first link 1833. The first link 1833 is rotatably coupled to the housing 1831.

[0346] The rotation axis 1833a of the first link becomes the rotation center for rotating the first link 1833. The rotation axis 1833a of the first link is rotatably coupled to the housing 1831.

[0347] The connection portion 1833 b of the first link 1833 extends from the rotation axis 1833 a of the first link in one direction, is connected to the connection hose 1832 , and is disposed at the end of the first link 1833 .

[0348] The connection portion 1833b of the first link is hingedly coupled to the inlet 1832a of the connection hose 1832. The first link 1833 is connected to the connection hose 1832 through the connection portion 1833b of the first link. Therefore, when the first link 1833 rotates, the connection hose 1832 may move.

[0349] The first link 1833 extends from the rotation shaft 1833a. The connection portion 1833b of the first link is disposed at a rear end portion of the first link 1833. The connection portion 1833b of the first link may be connected to the rear of the inlet 1832a of the connection hose 1832.

[0350] The first link 1833 includes a gear portion 1833c.

[0351] The gear portion 1833c of the first link 1833 may extend from the rotation axis 1833a of the first link in the opposite direction to the connection portion 1833b. The first link 1833 may extend forward from the rotation axis 1833a of the first link, and the gear portion 1833c of the first link is disposed at the front end of the first link 1833.

[0352] The end of the gear portion 1833c of the first link is formed with gear teeth. The gear portion 1833c of the first link 1833 is connected to the gear portion 1836c of the driving cam 1836. Specifically, the gear portion 1833c of the first link is meshed with the gear portion 1836c of the driving cam.

[0353] The first link includes a partition wall 1833d.

[0354] The partition wall 1833d of the first link is a component that prevents the flow path conversion module 183 from being separated when the connection hose 1832 is located at a specific position. Specifically, when the connection hose 1832 is not connected to the first cleaner flow path connection part 1831b, and the connection hose 1832 is connected to the second cleaner flow path part 1831c, or when the connection hose 1832 is located between the first cleaner flow path part 1831b and the second cleaner flow path part 1831c, the flow path conversion module 183 can be blocked from being separated.

[0355] The partition wall 1833d of the first link extends toward the radially outer side of the gear portion 1833c of the first link.

[0356] That is, the partition wall 1833d of the first connecting rod is arranged on a part of the gear portion 1833c of the first connecting rod. The partition wall 1833d of the first connecting rod covers a part of the gear portion 1833c. That is, a part of the gear portion 1833c of the first connecting rod overlaps with the partition wall 1833d, and the remaining part does not overlap with the partition wall 1833d. In addition, the gear portion 1836 of the driving cam meshing with the gear portion 1833c of the first connecting rod can make a part of the gear portion 1836c of the driving cam overlap with the partition wall 1833d as the driving cam 1836 rotates.

[0357] Therefore, when the assembly including the shell 1831 and the first link 1833 moves toward the side of the vacuum cleaner base station 100, as the driving cam 1836 rotates, the gear portion 1836c of the driving cam and the partition wall 1833d of the first link are stuck to each other, thereby limiting the separation of the assembly.

[0358] Specifically, as the driving cam 1836 rotates, if the gear portion 1836c of the driving cam and the partition wall 1833d are arranged at a position where they overlap each other, the partition wall 1833d is caught by the gear portion 1836c of the driving cam, making it impossible for the assembly to be separated. On the contrary, as the driving cam rotates, if the partition wall 1833d of the first link and the gear portion 1836c of the driving cam are arranged at a non-overlapping position, the flow path conversion module 183 can be easily separated.

[0359] More specifically, when the connecting hose 1832 is combined with the first vacuum cleaner flow path 181, the partition wall 1833d of the first connecting rod and the driving cam 1836 are not configured to overlap front and back. In addition, when the connecting hose 1832 is combined with the second vacuum cleaner flow path 182, the partition wall 1833d of the first connecting rod and the driving cam 1836 are configured to overlap front and back. In addition, when the connecting hose 1832 is configured between the first vacuum cleaner flow path 181 and the second vacuum cleaner flow path 182, the partition wall 1833d of the first connecting rod and the driving cam 1836 are configured to overlap front and back. Therefore, the flow path conversion module 183 can only be separated when the connecting hose 1832 is connected to the first vacuum cleaner flow path 181, thereby having an effect of preventing the falling dust from scattering through the first vacuum cleaner flow path 181 during the process of combining or separating.

[0360] The flow path switching module 183 includes a second link 1834. The second link 1834 is a component that moves the connection hose 1832 together with the first link 1833.

[0361] One side of the second link 1834 is rotatably coupled to the housing 1831 , and the other side is coupled to the connecting hose 1832 .

[0362] The second link 1834 rotates around a rotation axis 1834a disposed on one side. One side of the second link 1834 is rotatably coupled to the housing 1831. The second link 1834 rotates around a rotation axis 1834a disposed on one side. The rotation axis 1834a of the second link may be disposed at an end of the second link 1834. The second link 1834 is rotatably coupled to the housing 1831.

[0363] The rotation axis 1834a of the second link becomes the rotation center for rotating the second link 1834. The rotation axis 1834a of the second link extends from the second link 1834 toward the housing 1831. The rotation axis 1834a of the second link is rotatably coupled to the housing 1831.

[0364] The second link 1834 extends in one direction from a rotation axis 1834 a of the second link, and a connection portion 1834 b connected to the connection hose 1832 is provided at an end portion.

[0365] The connection portion 1834b of the second link is hingedly combined with the inlet of the connection hose 1832. The second link 1834 is connected to the connection hose 1832 through the connection portion 1834b of the second link. Therefore, when the second link 1834 rotates, the connection hose 1832 can move.

[0366] One side of the second link 1834 is coupled to the housing 1831, and the other side of the second link 1834 is coupled to the connection hose 1832. Specifically, one end of the second link 1834 becomes a rotation axis 1834a and is coupled to the housing 1831. The other end of the second link 1834 becomes a connection portion 1834b and is hingedly coupled to the inlet 1832a of the connection hose 1832.

[0367] The rotation axis 1834a of the second connecting rod is arranged at the lower part of the second connecting rod 1834 and is rotatably connected to the housing 1831. The second connecting rod 1834 is formed by extending upward from the rotation axis 1834a of the second connecting rod. A connecting portion 1834b of the second connecting rod is arranged at the upper end of the second connecting rod 1834. The connecting portion 1834b of the second connecting rod can be connected to the inlet of the connecting hose 1832.

[0368] Therefore, during the movement of the inlet of the connection hose 1832 , the inlet of the connection hose 1832 may be moved while being separated from the housing 1831 by a predetermined distance.

[0369] At least one of the rotation axis 1833 a of the first link and the rotation axis 1834 a of the second link is disposed apart from the central axis 1831 a of the housing 1831 .

[0370] The rotation axis 1833a of the first link may be disposed in front of the central axis 1831a of the housing 1831. The rotation axis 1834a of the second link may be disposed below the central axis 1831a of the housing 1831. The rotation axis 1833a of the first link is spaced apart from the rotation axis 1834a of the second link.

[0371] With such a configuration, the rotation axis 1833a of the first link and the rotation axis 1834a of the second link become two focal points, and the connecting hose 1832 can move along an elliptical trajectory. That is, the trajectory of movement of the connecting portion 1833b of the first link is offset from the trajectory of movement of the connecting portion 1834b of the second link, and the inlet 1832a of the connecting hose has an elliptical trajectory and moves.

[0372] Therefore, the inlet 1832a of the connection hose can be separated from the inner peripheral surface of the housing 1831 by a predetermined distance or more during the movement.

[0373] The connecting hose 1832 is tightly attached to the inner circumferential surface of the shell 1831 when combined with either the first cleaner flow path 181 or the second cleaner flow path 182, and is separated from the inner circumferential surface of the shell 1831 when moving from either the first cleaner flow path 181 or the second cleaner flow path 182 to the other.

[0374] Therefore, the seal 1832c of the connection hose 1832 can be prevented from being damaged by friction while moving between the first cleaner flow path connection portion 1831b and the second cleaner flow path connection portion 1831c.

[0375] In the flow path conversion module 183, the curvature radius of the inner circumference of the housing 1831 may be smaller than the curvature radius formed by the trajectory of the inlet 1832a of the connection hose 1832. The trajectory of the movement of the inlet 1832a of the connection hose 1832 may be formed in a shape similar to an ellipse, and the curvature radius of the ellipse may be larger than the curvature radius of the inner circumference of the housing 1831.

[0376] The trajectory of the inlet of the connecting hose 1832 is an ellipse with the rotation axis 1833a of the first link and the rotation axis (1833b) of the second link as foci. The curvature radius formed by the trajectory of the inlet 1832a of the connecting hose 1832 is of course greater than the curvature radius of the inner circumferential surface of the shell 1831.

[0377] Since the curvature radius of the ellipse is greater than the curvature radius of the inner circumferential surface of the housing 1831 , the inlet 1832 a of the connection hose 1832 may be spaced apart from the inner side of the inner circumferential surface of the housing 1831 when moving along the inner circumferential surface of the housing 1831 .

[0378] The flow path conversion module 183 includes a plurality of connecting rods, one side of which is rotatably coupled to the housing 1831 and the other side of which is coupled to the connecting hose 1832. The connecting rods may be a first connecting rod 1833 and a second connecting rod 1834.

[0379] In at least any one of the plurality of connecting rods, the radius of curvature of the trajectory along which the end connected to the housing 1831 moves may be greater than the radius of curvature of the inner circumferential surface of the housing 1831. The radius of curvature R2 of the second trajectory may be greater than the radius of curvature of the inner circumferential surface of the housing 1831, and the radius of curvature R1 of the first trajectory may be greater than the radius of curvature R2 of the second trajectory and the radius of curvature of the inner circumferential surface of the housing 1831.

[0380] The length of the first link 1833 may be greater than the length of the second link 1834 .

[0381] When the flow path conversion module 183 is viewed from one side, the first connecting rod 1833 may cross the second connecting rod 1834 .

[0382] As the length of the first link 1833 is formed to be different from the length of the second link 1834, and the first link 1833 and the second link 1834 are cross-configured, the inlet 1832a of the connecting hose 1832 can be separated from the inner circumferential surface of the shell 1831 during movement between the first vacuum cleaner flow path connection part 1831b and the second vacuum cleaner flow path connection part 1831c.

[0383] The flow path conversion module 183 includes a conversion motor 1835 and a driving cam 1836 .

[0384] The conversion motor 1835 is disposed on one side of the housing 1831 and generates power to move the connection hose 1832 .

[0385] The conversion motor 1835 may be a bidirectional motor that can rotate in two directions. That is, the conversion motor 1835 may rotate in a clockwise direction or a counterclockwise direction. For example, when the conversion motor 1835 rotates in a clockwise direction, the connection hose 1832 is connected to the second cleaner flow path 182. On the contrary, when the conversion motor 1835 rotates in a counterclockwise direction, the connection hose 1832 is connected to the first cleaner flow path 181.

[0386] The driving cam 1836 is coupled to the conversion motor 1835 to transmit the power of the conversion motor 1835 to the first connecting rod 1833 .

[0387] The driving cam 1836 is combined with the conversion motor 1835 and includes a detection portion 1836 b protruding to one side, which transmits the power of the conversion motor 1835 to the connecting hose 1832 .

[0388] The driving cam 1836 is coupled to the shaft of the conversion motor 1835. Thus, the driving cam 1836 and the shaft of the conversion motor 1835 rotate integrally.

[0389] The driving cam 1836 includes a gear portion 1836c. The gear portion 1836c of the driving cam may be formed in a shape protruding toward the radial outer side of the driving cam.

[0390] The gear portion 1836c of the driving cam is connected to the gear portion 1833c of the first connecting rod. That is, the gear portion 1836c of the driving cam is meshed and connected to the gear portion 1833c of the first connecting rod. Therefore, if the driving cam 1836 rotates in the clockwise direction, the first connecting rod 1833 rotates in the counterclockwise direction, and if the driving cam 1836 rotates in the counterclockwise direction, the first connecting rod 1833 rotates in the clockwise direction.

[0391] The flow path switching module 183 includes a detection unit 1836 b and a position sensor 1837 , and thus can determine the position of the connection hose 1832 .

[0392] The detection portion 1836 b is formed on the driving cam 1836 and protrudes toward the radially outer side of the shaft of the conversion motor 1835 .

[0393] The position sensor 1837 is disposed on one side of the detection portion 1836 b , and is turned on and off by the detection portion 1836 b , thereby detecting the position of the connection hose 1832 .

[0394] As an example, the position sensor 1837 includes a micro switch. The micro switch is arranged on one side of the detection unit 1836b. Therefore, when the detection unit 1836b is pressed (On), the micro switch sends a signal. On the contrary, when the detection unit 1836b is not pressed (Off), the micro switch does not send a signal.

[0395] The signal is transmitted to the control unit 400 , and the control unit 400 can determine the position of the connection hose 1832 based on whether there is a signal and the transmission time of the signal.

[0396] The detection portion 1836b may be composed of a plurality of surfaces. The plurality of surfaces may be outer peripheral surfaces formed radially outwardly around the rotation axis 1836a of the driving cam 1836, and the plurality of surfaces may be formed to have different radii around the rotation axis of the driving cam 1836.

[0397] Specifically, when the surface of the detection unit 1836b with a relatively large radius contacts the switch of the position sensor 1837, the position sensor 1837 is turned on by pressing the switch of the position sensor 1837, and the position sensor 1837 transmits an on signal to the control unit 400. On the contrary, when the surface of the detection unit 1836b with a relatively small radius faces the switch of the position sensor 1837, the switch of the position sensor 1837 is not pressed, and the position sensor 1837 is turned off, and the position sensor 1837 transmits an off signal to the control unit 400 or does not transmit a signal to the control unit 400.

[0398] The flow path conversion module 183 may further include an elastic member 1838. The elastic member 1838 is a component that facilitates movement of the inlet of the connection hose 1832.

[0399] One side of the elastic member 1838 is connected to the housing 1831 , and the other side is connected to the second connecting rod 1834 .

[0400] The elastic member 1838 may be a torsion spring.

[0401] The elastic member 1838 is stretched when the connection hose 1832 is connected to the first cleaner flow path 181. In addition, the elastic member 1838 is compressed when the connection hose 1832 is connected to the second cleaner flow path 182.

[0402] The elastic member 1838 helps the connection hose 1832 to move toward the first cleaner flow path 181 when the connection hose 1832 is connected to the second cleaner flow path 182. The first connecting rod 1833 can easily guide the connection hose 1832 to the second cleaner flow path 182 by pulling the connection hose 1832 connected to the first cleaner flow path 181 backward. In contrast, the first connecting rod 1833 guides the connection hose 1832 connected to the second cleaner flow path 182 to the first cleaner flow path 181 by pushing it to the upper front side, and a part of the connection hose 1832 may be hooked on the path where the connection hose 1832 moves. At this time, the elastic force of the elastic member 1838 pulls the connection portion 1834b of the second connecting rod 1834, so that the connection hose 1832 can be easily separated from the second cleaner flow path 182.

[0403] The flow path switching module 183 includes a stop sensor 1839 and a stopper 1836d, thereby being able to block the connection hose 1832 from moving above the limit position.

[0404] The stopper 1836d is arranged on one side of the driving cam 1836. The stopper 1836d protrudes from the driving cam 1835 toward the radially outer side.

[0405] The stop sensor 1839 may be disposed adjacent to the drive cam 1836 .

[0406] The stop sensor 1839 may be an infrared sensor or a contact sensor. The stop sensor 1839 may detect the position of the stopper 1836d and send a signal when the stopper 1836d is arranged near the stop sensor 1839. In addition, the signal sent by the stop sensor 1839 is transmitted to the control unit 400.

[0407] When receiving a signal from the stop sensor 1839 , the control unit 400 may determine that the connection hose 1832 is completely connected to the first cleaner flow path 181 and stop the operation of the conversion motor 1835 .

[0408] The flow path conversion module 183 of the present invention can be detachably combined with the housing 110. The housing 110 is formed with a chamber in which the flow path conversion module 183 can be disposed. The flow path conversion module 183 is disposed in the chamber. The first and second cleaner flow paths 181 and 182 are connected to the dust collection flow path 184.

[0409] Air and dust flow through the flow path conversion module 183, and there is a risk of malfunction due to dust pollution or dust accumulation. Therefore, it is necessary to facilitate separation and cleaning. According to the present invention, the flow path conversion module 183 can be easily combined with or separated from the cover body 110, so it has the effect of easy separation and cleaning.

[0410] The connecting hose 1832 and the first connecting rod 1833 are combined with the housing 1831 to form a component, and the component can be combined or separated from the housing 110 as a whole. The housing 1831, the connecting hose 1832, the first connecting rod 1833 and the second connecting rod 1834 can form a component. The component can be assembled before being combined with the housing 110, and can be combined or separated from the housing 110 as a component.

[0411] Each flange of the assembly can be slidably inserted into a plurality of flange grooves, so that the assembly is combined with the cover body 110. After the assembly is combined with the cover body 110, screws or the like can be used to more firmly fix them.

[0412] The flow path conversion module 183 is detachably coupled to the housing 110, but is detached when connected to either the first cleaner flow path 181 or the second cleaner flow path 182. For example, the flow path conversion module 183 may be detached when the connecting hose 1832 is connected to the first cleaner flow path 181, and when the connecting hose 1832 is connected to the second cleaner flow path 182, the partition wall 1833d may be caught by the gear portion 1836c of the driving cam and be restricted from being separated.

[0413] One side of the dust collecting passage 184 is selectively connected to either the first dust collector passage 181 or the second dust collector passage 182, and the other side is connected to the dust collecting unit 170. For example, the upper end of the dust collecting passage 184 is selectively connected to either the first dust collector passage 181 or the second dust collector passage 182, and the lower end is connected to the dust collecting unit 170.

[0414] On the other hand, in this embodiment, a virtual line may be formed that penetrates the inside of the dust collection flow path 184. That is, the vacuum cleaner base station 100 of the present invention may include a virtual dust collection flow path penetration line P3 that penetrates the dust collection flow path 184 along the length direction.

[0415] The dust collection passage penetration line P3 may be formed along the length direction (axial direction) of the dust collection passage 184, and may be formed to penetrate the interior of the dust collection passage 184. The dust collection passage penetration line P3 is arranged along the vertical line V.

[0416] The inlet of the dust collecting passage 184 is coupled to the housing 1831 and communicates with a connecting hose 1832 coupled to the housing 1831 .

[0417] like Fig.14 As described above, when the connecting hose 1832 is connected to the first dust collector flow path 181, the dust collection flow path 184 is connected to the first dust collector flow path 181, and air can flow in the dust collection flow path 184. Fig.15As shown, when the connecting hose 1832 is connected to the second cleaner flow path 182 , the dust collecting flow path 184 is connected to the second cleaner flow path 182 , and air can flow in the dust collecting flow path 184 .

[0418] On the other hand, refer to Figure 7 and Fig.16 , the dust suction module 190 is described as follows.

[0419] The cleaner base station 100 may include a dust suction module 190. The dust suction module 190 may include a dust collecting motor 191, a first filter (not shown) and a second filter (not shown).

[0420] The dust collecting motor 191 may be disposed at the lower portion of the dust collecting portion 170. The dust collecting motor 191 may generate suction force toward the flow path portion 180. Thus, the dust collecting motor 191 may provide suction force capable of sucking dust in the dust container 220 of the cleaner 200.

[0421] The dust collecting motor 191 can generate suction force by rotation. As an example, the dust collecting motor 191 can be formed in a shape similar to a cylinder.

[0422] On the other hand, in the present embodiment, a virtual dust collecting motor axis C extending the rotation axis of the dust collecting motor 191 may be formed.

[0423] The first filter (not shown) may be disposed between the dust collecting portion 170 and the dust collecting motor 191. The first filter may be a pre-filter.

[0424] The second filter (not shown) may be disposed between the dust collecting motor 191 and the outer wall surface 112. The second filter (not shown) may be a high efficiency air (HEPA) filter.

[0425] On the other hand, the vacuum cleaner base station 100 may further include a charging unit 128. The charging unit 128 may be disposed at the coupling portion 120. The charging unit 128 may be electrically connected to the first vacuum cleaner 200 coupled to the coupling portion 120. The charging unit 128 may supply power to a battery of the first vacuum cleaner 200 coupled to the coupling portion 120.

[0426] In addition, the vacuum cleaner base station 100 may further include a side door (not shown). The side door may be disposed on the cover body 110. The side door may selectively expose the dust collecting unit 170 to the outside. Thus, the user can easily remove the dust collecting unit 170 from the vacuum cleaner base station 100.

[0427] on the other hand, Fig.16 A block diagram for illustrating the control structure in a vacuum cleaner base station according to an embodiment of the present invention is disclosed.

[0428] Reference Fig.16, the control structure of the vacuum cleaner base station 100 of the present invention is described as follows.

[0429] The vacuum cleaner base station 100 of the embodiment of the present invention may further include a control unit 400 that controls the combining portion 120 , the fixing unit 130 , the door unit 140 , the cover opening unit 150 , the lower combining portion 160 , the dust collecting portion 170 , the flow path portion 180 , and the dust suction module 190 .

[0430] The control unit 400 may include a printed circuit board and a plurality of components mounted on the printed circuit board.

[0431] If the coupling sensor 125 senses the coupling of the first cleaner 200, the coupling sensor 125 may send a signal that the first cleaner 200 is coupled to the coupling portion 120. At this time, the control portion 400 may receive the signal of the coupling sensor 125 and determine that the first cleaner 200 is coupled to the coupling portion 120.

[0432] In addition, if power is supplied from the charging unit 128 to the battery 240 of the first cleaner 200 , the control unit 400 may determine that the first cleaner 200 has been coupled to the coupling unit 120 .

[0433] If it is determined that the first cleaner 200 is coupled to the coupling portion 120 , the control portion 400 may fix the first cleaner 200 by operating the fixing portion motor 133 .

[0434] If the fixing member 131 or the fixing part link 135 moves to the prescribed fixing position FP1, the fixing sensor 137 may send a signal indicating that the first vacuum cleaner 200 has been fixed. The base station control unit 400 may receive the signal indicating that the first vacuum cleaner 200 has been fixed from the fixing sensor 137 and determine that the first vacuum cleaner 200 has been fixed. If it is determined that the first vacuum cleaner 200 has been fixed, the base station control unit 400 may interrupt the operation of the fixing part motor 133.

[0435] On the other hand, if the dust container 220 is emptied, the controller 400 may release the fixing of the first cleaner 200 by rotating the fixing unit motor 133 in the reverse direction.

[0436] If it is determined that the first cleaner 200 is fixed to the coupling portion 120 , the control portion 400 may open the door 141 of the cleaner base station 100 by operating the door motor 142 .

[0437] If the door 141 or the door arm 143 reaches the specified opening position DP1, the door opening and closing sensor 144 may send a signal indicating that the door 141 is opened. The control unit 400 may receive the signal indicating that the door 141 is opened from the door opening and closing sensor 137 and determine that the door 141 is opened. If it is determined that the door 141 is opened, the control unit 400 may interrupt the operation of the door motor 142.

[0438] On the other hand, if the emptying of the dust container 220 is completed, the control part 400 may close the door 141 by rotating the door motor 142 in the reverse direction.

[0439] If it is determined that the door 141 is opened, the control unit 400 may open the discharge cover 222 of the first cleaner 200 by operating the cover opening motor 152 .

[0440] The control unit 400 may receive a signal indicating that the discharge cover 222 is opened from the cover opening sensor 155f to determine that the discharge cover 222 is opened. If it is determined that the discharge cover 222 is opened, the control unit 400 may interrupt the operation of the cover opening motor 152.

[0441] If the second cleaner 300 is coupled to the lower coupling portion 160 , power may be applied to the second cleaner 300 through a charging terminal (not shown), whereby the control unit 400 may determine that the second cleaner 300 is coupled to the lower coupling portion 160 .

[0442] The control unit 400 may control the sterilization module 175. For example, the control unit 400 may operate the sterilization module 175 after the dust collecting unit 170 collects dust or at a predetermined time interval to sterilize viruses or microorganisms existing inside or outside the dust collecting unit 170.

[0443] The control unit 400 can control the flow path conversion module 183 of the flow path unit 180. As an example, the control unit 400 can control the conversion motor 1835 to move the connection hose 1832. The connection hose 1832 can be selectively connected to the first cleaner flow path 181 or the second cleaner flow path 182. Therefore, the control unit 400 can selectively open and close the first cleaner flow path 181 or the second cleaner flow path 182 by moving the connection hose 1832.

[0444] The control unit 400 may drive the dust collecting motor 191 to suck in the dust inside the dust container 220 .

[0445] The control unit 400 may display the emptying status and charging status of the dust container of the first vacuum cleaner 200 or the second vacuum cleaner 300 through the operation display unit 410 .

[0446] On the other hand, the vacuum cleaner base station 100 of the present invention may include a display unit 410 .

[0447] The display unit 410 may be disposed on the cover body 110 , or may be disposed on a separate display device, and may be provided in a terminal including a mobile phone.

[0448] The display unit 410 may include at least one of a display panel capable of outputting text and / or graphics and a speaker capable of outputting voice signals and sounds. The user can easily grasp the status of the currently ongoing operation, the remaining time, etc. through the information output by the display unit.

[0449] On the other hand, the vacuum cleaner base station 100 according to the embodiment of the present invention may include a memory 430. The memory 430 may contain various data used for driving and operating the vacuum cleaner base station 100.

[0450] On the other hand, the vacuum cleaner base station 100 of the embodiment of the present invention may include an input unit 440. The input unit 440 generates key input data input by the user to control the action of the vacuum cleaner base station 100. To this end, the input unit 440 may be composed of a keyboard (keypad), a dome switch (dome switch), a touch panel (static pressure / static electricity), etc. In particular, when the touch panel and the display unit 410 form a layer structure with each other, it can be called a touch screen (touch screen).

[0451] Reference Figure 7 , Fig.14 and Fig.15 The relationship between the vacuum cleaner base station and the flow path portion when the first vacuum cleaner 200 is placed on the vacuum cleaner base station 100 is described as follows.

[0452] In the present invention, the first vacuum cleaner 200 can be placed on the outer wall surface 112 of the vacuum cleaner base station 100. As an example, the dust bucket 220 and the battery cover 230 of the first vacuum cleaner 200 can be combined with the combination surface 121 of the vacuum cleaner base station 100. That is, the first vacuum cleaner 200 can be placed on the first outer wall surface 112a.

[0453] At this time, the suction motor axis a1 can be vertically configured to the first outer wall surface 112a. That is, the suction motor axis a1 can be formed to be parallel to the ground. The suction motor axis a1 can be formed on a plane perpendicular to the ground. In addition, the suction motor axis a1 can be formed on a plane perpendicular to the first outer wall surface 112a. The suction motor axis a1 can indicate the direction in which the suction force of the suction motor 214 is applied.

[0454] The suction flow path through line a2 may be formed parallel to the first outer wall surface 112a. The suction flow path through line a2 may be formed along the gravity direction. That is, the suction flow path through line a2 may be formed perpendicular to the ground. In addition, the suction flow path through line a2 may be formed on a plane perpendicularly intersecting the first outer wall surface 112a. The suction flow path through line a2 may indicate the direction in which the external air flows in as the suction motor 214 or the dust collecting motor 191 operates.

[0455] The grip portion penetration line a3 may be formed obliquely to form a predetermined angle with the first outer wall surface 112a. In addition, the grip portion penetration line a3 may be formed obliquely to form a predetermined angle with the ground. The grip portion penetration line a3 may be formed on a plane perpendicularly intersecting the first outer wall surface 112a.

[0456] The cyclone line a4 may be formed perpendicularly to the first outer wall surface 112a. That is, the cyclone line a4 may be formed parallel to the ground. The cyclone line a4 may be formed on a plane perpendicular to the ground. In addition, the cyclone line a4 may be formed on a plane perpendicularly intersecting the first outer wall surface 112a. The cyclone line a4 may represent the axis of the cyclonic flow of the air flowing into the first cleaner 200.

[0457] The dust bucket penetration line a5 may be formed perpendicularly to the first outer wall surface 112a. That is, the dust bucket penetration line a5 may be formed parallel to the ground. The dust bucket penetration line a5 may be formed on a plane perpendicular to the ground. In addition, the dust bucket penetration line a5 may be formed on a plane perpendicularly intersecting the first outer wall surface 112a. The dust bucket penetration line a5 may indicate the direction in which air and foreign matter flow into the first flow path 181a through the dust bucket 220 as the dust collecting motor 191 operates.

[0458] The dust collecting motor axis C may be formed to be perpendicular to the ground. The dust collecting motor axis C may be formed to be parallel to at least one of the first outer wall surface 112a, the second outer wall surface 112b, the third outer wall surface 112c, and the fourth outer wall surface 112d. The dust collecting motor axis C may indicate the direction in which the suction force of the dust collecting motor 191 is applied.

[0459] In the relationship between the first cleaner flow path penetration line P1 and a vertical line V perpendicular to the ground, the first cleaner flow path penetration line P1 may be arranged to have an angle difference with the vertical line V of a predetermined dust inflow angle θ.

[0460] Here, the vertical line V may be a virtual line formed in a direction perpendicular to the ground. In addition, the vertical line V may be arranged parallel to the dust collecting motor axis C. Therefore, the vertical line V may indicate the direction of the suction force applied to the dust collecting flow path 184 when the dust collecting motor 191 is running. In addition, the vertical line V may indicate the direction of gravity based on the vacuum cleaner base station 100 being placed on the ground.

[0461] In other words, the second flow path 181 b of the first cleaner flow path 181 and the dust collecting flow path 184 may be configured to be inclined at the dust inflow angle θ.

[0462] On the other hand, in the relationship between the second cleaner flow path penetration line P2 and the horizontal line H parallel to the ground, the second cleaner flow path penetration line P2 may be configured to be inclined with respect to the horizontal line H at a predetermined dust suction angle β.

[0463] Here, the horizontal line H may be a virtual line formed in a direction horizontal to the ground.

[0464] On the other hand, the dust collection flow path penetration line P3 may be arranged to be parallel to a vertical line V which is perpendicular to the ground.

[0465] Here, the dust collection flow path penetration line P3 may indicate the direction of air flowing into the dust collecting portion 170 through the first cleaner flow path 181 or the second cleaner flow path 182 .

[0466] On the other hand, the relationship between the suction motor axis a1, the suction flow path through line a2, the gripping portion through line a3, the cyclone line a4, the dust bin through line a5, the dust collecting motor axis C, the vertical line V, the horizontal line H, the first vacuum cleaner flow path through line P1 and the second vacuum cleaner flow path through line P2 in the vacuum cleaner system of an embodiment of the present invention is described as follows.

[0467] The vertical line V may intersect the suction motor axis a1 vertically. Alternatively, the vertical line V may intersect the cyclone line a4 vertically. Alternatively, the vertical line V may intersect the dust bin penetration line a5 vertically.

[0468] The horizontal line H may be arranged in parallel with the suction motor axis a1. Alternatively, the horizontal line H may be arranged in parallel with the cyclone line a4. Alternatively, the horizontal line H may be arranged in parallel with the dust bin penetration line a5.

[0469] The first cleaner flow path penetration line P1 may be configured to be inclined at a dust inflow angle θ with respect to the vertical line V. Fig.12 As shown, the dust inflow angle θ may represent an angle at which the first cleaner flow path penetration line P1 rotates in a clockwise or counterclockwise direction with respect to the vertical line V.

[0470] When the dust inflow angle θ is 0 degrees, the direction in which the suction force of the dust collecting motor 191 is applied is arranged along the formation direction of the second flow path 181 b , so that air and foreign matter can be collected without flow path loss.

[0471] On the other hand, as the dust inflow angle θ increases, the flow path loss may increase. That is, as the bending angle of the portion of the second flow path 181b connected to the dust collecting flow path 184 increases, the flow path loss may increase.

[0472] Therefore, the dust inflow angle θ is preferably greater than 0 degrees and less than 10 degrees. When the dust inflow angle θ is less than 10 degrees, the flow path loss is less than 5% regardless of the diameter of the flow path. Therefore, when the dust inflow angle θ is less than 10 degrees, the suction force against the dust does not decrease.

[0473] In contrast, when the dust inflow angle θ exceeds 10 degrees, the flow path loss may increase. In particular, when the diameter of the flow path is small, the flow path loss may further increase sharply. For example, when the dust inflow angle θ exceeds 10 degrees and the diameter D of the flow path is the same as the curvature radius R of the bending flow path, the flow path loss may be 14% or more. Therefore, when the dust inflow angle θ exceeds 10 degrees, the suction force may decrease due to the flow path loss.

[0474] Therefore, in this embodiment, the dust inflow angle θ is configured to be greater than 0 degrees and less than 10 degrees, thereby having the effect of preventing the suction force from decreasing during the dust collection process.

[0475] On the other hand, the dust bin penetration line a5 may intersect with the first cleaner flow path penetration line P1. At this time, the dust bin penetration line a5 and the first cleaner flow path penetration line P1 may intersect with each other in the flow path portion 180. In addition, the dust bin penetration line a5 may intersect with the first cleaner flow path penetration line P1 at an angle difference of a predetermined descending angle α.

[0476] At this time, the vertical line V and the dust bucket penetration line a5 may intersect each other perpendicularly, the vertical line V and the first cleaner flow path penetration line P1 may intersect at an angle difference of the dust inflow angle θ, and the descending angle α may have a magnitude of 90° minus the dust inflow angle θ (α=90°-θ). For example, the descending angle α may be greater than 80 degrees and less than 90 degrees.

[0477] In addition to utilizing the suction force of the dust collecting motor 191 to collect foreign matter in the dust container 220 of the first vacuum cleaner 200 , the above configuration also has the effect of utilizing gravity to collect foreign matter.

[0478] Furthermore, in the present embodiment, the upper diameter of the second flow path 181 b is larger than the lower diameter, so that the air flows downward and the flow rate gradually increases.

[0479] Therefore, although the dust container penetration line a5 is perpendicular to the dust collecting motor axis C, according to the present invention, there is an effect of minimizing the flow path loss in the process of collecting foreign matter in the dust container 220 and maximizing the dust collecting function.

[0480] On the other hand, the second cleaner flow path penetration line P2 is configured to have an inclination of the dust suction angle β in relation to the horizontal line H. Fig.13 As shown, the dust suction angle β can represent the angle at which the second cleaner flow path penetration line P2 rotates clockwise or counterclockwise with respect to the horizontal line H.

[0481] The dust suction angle β may represent the angle at which the dust-containing air passing through the fourth flow path 182b descends. In addition, the dust suction angle β may represent the angle at which the air existing in the dust collection flow path 184 or the connection hose 1832 flows back to the fourth flow path 182b.

[0482] At this time, the dust suction angle β may exceed 0 degrees.

[0483] According to the above configuration, even if the operation of the dust collecting motor 191 ends, the dust passing through the fourth flow path 182b will not remain on the fifth flow path 182c, but will flow to the dust collecting flow path 184 under the action of gravity. Therefore, according to the present invention, even if the operation of the dust collecting motor 191 ends, the dust in the air can be prevented from flowing back and scattering.

[0484] In addition, the dust suction angle β may be configured to be smaller than the descending angle α (β<α).

[0485] This may indicate that the fifth flow path 182c is disposed between the first flow path 181a and the dust collecting flow path 184. According to the above configuration, the height of the upper end portion in the gravity direction of the fourth flow path 182b may be configured to be closer to the ground than the first flow path 181a. This has the effect of minimizing the distance that the air exhausted from the second vacuum cleaner 300 overcomes gravity and flows upward along the fourth flow path 182b.

[0486] Furthermore, in this embodiment, the diameter of the fourth flow path 182b is smaller than the diameter of the fifth flow path 182c. Therefore, the flow rate of air passing through the fourth flow path 182b can be greater than the flow rate of air passing through the fifth flow path 182c, which can provide sufficient dust collecting power for the second vacuum cleaner 300.

[0487] When the first vacuum cleaner 200 is coupled to the vacuum cleaner base station 100 , the suction motor axis a1 may intersect the dust collection motor axis C at a predetermined angle.

[0488] In addition, when the first vacuum cleaner 200 is coupled to the vacuum cleaner base station 100 , the suction motor axis a1 may intersect a vertical line V of the ground at a predetermined angle.

[0489] On the other hand, when the first vacuum cleaner 200 is coupled to the vacuum cleaner base station 100, the handle 216 can be arranged at a position farther than the suction motor axis a1 with respect to the ground. According to the above configuration, when the user holds the handle 216, the relatively heavy suction motor 214 is located at the lower side in the direction of gravity, thereby providing convenience, that is, the user can couple or separate the first vacuum cleaner 200 to or from the vacuum cleaner base station 100 by simply moving the first vacuum cleaner 200 in a direction parallel to the ground.

[0490] The suction flow path penetration line a2 may intersect with the suction flow path axis a1, the grip portion penetration line a3, the cyclone line a4, or the dust bin penetration line a5.

[0491] As an example, the suction flow path through line a2 may intersect the suction flow path axis a1 perpendicularly. In addition, the suction flow path through line a2 may intersect the grip portion through line a3 at a specified angle. In addition, the suction flow path through line a2 may intersect the cyclone line a4 perpendicularly. In addition, the suction flow path through line a2 may intersect the dust bin through line a5 perpendicularly.

[0492] When the first vacuum cleaner 200 is coupled to the vacuum cleaner base station 100 , the suction flow path penetration line a2 may be formed parallel to the dust collecting motor axis C. This configuration has the effect of minimizing the space occupied on the horizontal plane when the first vacuum cleaner 200 is coupled to the vacuum cleaner base station 100 .

[0493] At this time, a coupling portion 120 may be disposed between the suction flow path through line a2 and the dust collecting motor axis C. A fixing member 131 may be disposed between the suction flow path through line a2 and the dust collecting motor axis C. A cover opening unit 150 may be disposed between the suction flow path through line a2 and the dust collecting motor axis C. According to the above configuration, the user can couple or separate the first vacuum cleaner 200 to or from the vacuum cleaner base station 100 by simply moving the first vacuum cleaner 200 in a direction parallel to the ground, and the dust bucket 220 can be fixed, and the convenience of being able to open the dust bucket 220 is provided.

[0494] The grip portion penetration line a3 may intersect with the suction flow path axis a1, the suction flow path penetration line a2, the cyclone line a4, or the dust bin penetration line a5.

[0495] When the first vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the height from the ground to the intersection of the grip portion penetration line a3 and the suction flow path penetration line a2 can be less than the maximum height of the cover body 110. With such a configuration, the overall volume of the first vacuum cleaner 200 in the state of being combined with the vacuum cleaner base station 100 can be minimized.

[0496] The gripping portion through line a3 may intersect the dust collecting motor axis C at a specified angle. At this time, the intersection point P6 of the gripping portion through line a3 and the dust collecting motor axis C may be located inside the cover body 110. According to the above configuration, there is an advantage that when the user holds the first vacuum cleaner 200, the first vacuum cleaner 200 can be coupled to the vacuum cleaner base station 100 by simply extending the arm to the side of the vacuum cleaner base station 100. In addition, a relatively heavy dust collecting motor 191 is accommodated inside the cover body 110, so that even if the user pushes the first vacuum cleaner 200 into the vacuum cleaner base station 100 forcefully, the vacuum cleaner base station 100 can be prevented from shaking.

[0497] The cyclone line a4 may be formed on the same axis as the suction motor axis a1 or the dust container penetration line a5. The above configuration has the effect of reducing flow path loss during cleaning.

[0498] Although not shown, as another example, the cyclone line a4 may be formed parallel to the suction motor axis a1 or the dust bin penetration line a5 at a predetermined interval. In addition, as another example, the cyclone line a4 may be formed perpendicular to the suction motor axis a1 or the dust bin penetration line a5.

[0499] When the first vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the cyclone line a4 may intersect the longitudinal axis of the vacuum cleaner base station 100. That is, the axis of the flow of the dust separation unit 213 may intersect the longitudinal axis of the vacuum cleaner base station 100. At this time, the intersection of the axis of the flow of the dust separation unit 213 and the longitudinal axis of the vacuum cleaner base station 100 may be located inside the cover body 110, more specifically, inside the flow path 180.

[0500] When the first vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the cyclone line a4 may intersect with the dust collecting motor axis C. At this time, there may be an intersection between the cyclone line a4 and the dust collecting motor axis C. The intersection of the cyclone line a4 and the dust collecting motor axis C may be located inside the cover body 110, and more specifically, may be located inside the flow path portion 180. The above configuration has the following effects: when the first vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the first vacuum cleaner 200 can be stably supported by the vacuum cleaner base station 100, and when the dust bin 220 is emptied, the flow path loss can be reduced.

[0501] The cyclone line a4 may intersect the dust collecting motor axis C at a predetermined angle.

[0502] The dust container penetration line a5 may be formed on the same axis as the suction motor axis a1 or the cyclone line a4. The above configuration has the effect of reducing flow path loss during cleaning.

[0503] When the first vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the dust bucket penetration line a5 may intersect the longitudinal axis of the vacuum cleaner base station 100. That is, the longitudinal axis of the dust bucket 220 may intersect the longitudinal axis of the vacuum cleaner base station 100. At this time, the intersection of the longitudinal axis of the dust bucket 220 and the longitudinal axis of the vacuum cleaner base station 100 may be located inside the cover body 110, more specifically, inside the flow path portion 180.

[0504] The dust container penetration line a5 may intersect the dust collecting motor axis C at a predetermined angle.

[0505] On the other hand, when the first vacuum cleaner 200 is coupled to the vacuum cleaner base station 100, the handle 216 can be disposed at a position farther from the dust bucket penetration line a5 based on the ground. According to the above configuration, convenience can be provided, that is, when the user holds the handle 216, the user can couple or separate the first vacuum cleaner 200 to or from the vacuum cleaner base station 100 by simply moving the first vacuum cleaner 200 in a direction parallel to the ground.

[0506] In addition, when the first vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the battery 240 can be arranged at a position farther than the dust bucket penetration line a5 based on the ground. With such a configuration, the battery 240 presses the main body 210 of the first vacuum cleaner 200 under the action of its own weight, so that the first vacuum cleaner 200 is stably supported by the vacuum cleaner base station 100.

[0507] On the other hand, the dust container penetration line a5 and the dust collection flow path penetration line P3 may intersect each other. At this time, the dust container penetration line a5 and the dust collection flow path penetration line P3 may intersect each other in the flow path portion 180.

[0508] At this time, the dust container penetration line a5 and the dust collection flow path penetration line P3 may intersect each other perpendicularly.

[0509] In addition to utilizing the suction force of the dust collecting motor 191 to collect foreign matter in the dust container 220 of the first vacuum cleaner 200 , this configuration also has the effect of utilizing gravity to collect foreign matter.

[0510] On the other hand, in this embodiment, a virtual plane S1 may be formed, which is formed along the long axis direction connecting the front and rear of the first vacuum cleaner 200, and the entire weight of the first vacuum cleaner 200 is concentrated on the virtual plane S1.

[0511] Specifically, the virtual plane S1 may include at least two of the suction motor axis a1, the suction flow path penetration line a2, the grip portion penetration line a3, the cyclone line a4, the dust bin penetration line a5, and the dust collection motor axis C to form the virtual plane S1. That is, the plane S1 may be a virtual plane formed by connecting two virtual straight lines to each other, and may include a virtual plane that expands the two virtual straight lines.

[0512] The virtual extension surface of the plane S1 may pass through the first vacuum cleaner 200 .

[0513] As an example, the virtual extension surface of the plane S1 may pass through the suction part 212. Alternatively, the virtual extension surface of the plane S1 may pass through the dust separation part 213. Alternatively, the virtual extension surface of the plane S1 may pass through the suction motor 214. Alternatively, the virtual extension surface of the plane S1 may pass through the handle 216. Alternatively, the virtual extension surface of the plane S1 may pass through the dust bin 220.

[0514] In addition, when the first vacuum cleaner 200 is placed on the vacuum cleaner base station 100 , the virtual extension surface of the plane S1 may pass through at least a portion of the vacuum cleaner base station 100 .

[0515] Therefore, when the first vacuum cleaner 200 is placed on the vacuum cleaner base station 100 , the plane S1 may penetrate (pass through) the cover body 110 .

[0516] The virtual extension surface of the plane S1 may penetrate the flow path portion 180. In this case, the loss of the flow path of the air extending from the dust container 220 to the dust collecting portion 170 can be minimized.

[0517] On the other hand, if the first vacuum cleaner 200 is placed on the vacuum cleaner base station 100, at least a portion of the outer peripheral surface of the dust bucket 220 may be surrounded by the dust bucket guide surface 122. When the first flow path 181a is arranged behind the dust bucket 220 and the dust bucket 220 is opened, the internal space of the dust bucket 220 may be connected to the first flow path 181a. In addition, the second flow path 181b may be bent downward (toward the ground) from the first flow path 181a.

[0518] On the other hand, if the second vacuum cleaner 300 is combined with the vacuum cleaner base station 100, the dust discharge hole 320 of the dust bucket 310 can be connected to the dust suction hole 162 of the lower joint 160. The third flow path 182a is arranged behind the dust suction hole 162, so when the dust collecting motor 191 is running, the internal space of the dust bucket 310 can be connected to the third flow path 182a. In addition, the fourth flow path 182b can be bent upward from the third flow path 182a. In addition, the fifth flow path 182c can be bent downward at a specified angle from the fourth flow path 182b.

[0519] In addition, the dust collecting part 170 can be arranged at a position closer to the ground than the second flow path 181b. In addition, a flow path conversion module 183 can be arranged between the second flow path 181b and the dust collecting part 170. In addition, a fifth flow path 182c can be arranged between the first flow path 181a and the dust collecting part 170. In addition, the dust suction module 190 can be arranged at a position closer to the ground than the dust collecting part 170. In addition, the lower joint 160 can be arranged at a position closer to the ground than the dust suction module 190. In addition, the third flow path 182a can be arranged at a position closer to the ground than the dust suction module 190.

[0520] According to the above structure, according to the present invention, the upper part of the vacuum cleaner base station 100 can be combined with the first vacuum cleaner 200, and the lower part of the vacuum cleaner base station 100 can be combined with the second vacuum cleaner 300. Therefore, when the first vacuum cleaner 200 and the second vacuum cleaner 300 are both combined with the vacuum cleaner base station 100, the space occupied on the horizontal plane can be minimized.

[0521] In addition, according to the present invention, there is an effect that even if the first cleaner flow path 181 communicating with the dust container 220 of the first cleaner 200 is formed by bending once, loss of flow force for collecting dust can be prevented.

[0522] In addition, according to the present invention, the following effect is achieved: even if the second vacuum cleaner flow path 182 connected to the dust bin 310 of the second vacuum cleaner 300 is arranged at a position closer to the lower side than the dust collecting motor 191, and the second vacuum cleaner flow path 192 is bent twice, it is possible to prevent dust (foreign matter) from flowing back and fully suck the dust into the dust collecting section 170.

[0523] The above is a detailed description through the specific embodiments of the present invention, but it is only used to specifically illustrate the present invention, and the present invention is not limited thereto. Obviously, the present invention can be modified or improved by ordinary technicians in the technical field to which the present invention belongs within the scope of the technical idea of ​​the present invention.
