Description

Technical Field

[0001] The present invention relates to a vacuum cleaner base station that is combined with a vacuum cleaner to collect dust inside the dust bin of the vacuum cleaner. Background Art

[0002] A hassle with a stick vacuum cleaner (hereinafter referred to as "vacuum cleaner") is that the capacity of the dust bin for storing the collected dust is small, so the user needs to empty the dust bin each time.

[0003] Therefore, in order to prevent the user from manually removing the dust from the dust bin, the use of a vacuum cleaner base station that sucks and collects the dust in the dust bin by the suction force of a dust collection motor is being expanded.

[0004] Such a vacuum cleaner base station includes a housing, a dust collection motor disposed inside the housing, and a collection unit in the form of a dust bag for accommodating the collected dust, and the vacuum cleaner base station is configured to be combined with a vacuum cleaner or the dust bin of the vacuum cleaner.

[0005] The convenience of the vacuum cleaner base station is that it can automatically empty the dust bin of the vacuum cleaner. Most of the dust bags included in the vacuum cleaner base station have a larger volume than the dust bin provided in the vacuum cleaner, so it has the advantage of a long dust processing cycle.

[0006] On the other hand, the collection unit in the form of a dust bag has a simple structure and does not require separate dust removal or internal cleaning. The entire dust bag can be thrown into the trash can, which has an advantage in terms of user convenience.

[0007] However, since the inside of the dust bag cannot be cleaned, it needs to be periodically purchased and replaced, which may burden the user in terms of cost.

[0008] Regarding this, as an existing patent document, U.S. Patent No. 10,595,692 is proposed.

[0009] In the above-mentioned existing patent document, an embodiment of a discharge station having a collection unit in the form of a bin as a discharge station for docking with a robotic vacuum cleaner is disclosed.

[0010] Unlike a dust bag, the collection unit in the form of a "bin" is easy to clean inside, so it has the advantage of being able to be used semi-permanently as long as the accommodated dust is removed.

[0011] However, some users may find it troublesome to remove and clean the dust that requires separate operations.

[0012] As described above, when the form of the collection unit is fixed to a certain type, it is difficult to meet the preferences of different users. Summary of the Invention

[0013] Problems to be Solved by the Invention

[0014] An object of the present invention is to provide a vacuum cleaner base station that can satisfy various preferences of users who like collection parts in different forms.

[0015] In addition, an object of the present invention is to provide a vacuum cleaner base station that can distinguish different forms of collection parts currently in use.

[0016] The problems of the present invention are not limited to the problems mentioned above, and those skilled in the art can clearly understand other unmentioned problems through the following description of the specific content for implementing the present invention.

[0017] Technical Solutions for Solving the Problems

[0018] A vacuum cleaner base station according to an embodiment of the present invention for achieving the above object may include: a cover body coupled to a dust bin of a vacuum cleaner; a dust collection motor disposed inside the cover body to generate a suction force for sucking dust inside the dust bin; a collection part having a dust accommodation space for collecting dust sucked from inside the dust bin by the dust collection motor; and a chamber part disposed in the cover body to form a collection part accommodation space for detachably coupling the collection part to the chamber part.

[0019] In the collection parts coupled to the chamber part, a first collection part and a second collection part may be compatible with each other. The first collection part has a barrel shape with a fixed size of the dust accommodation space and includes a cyclone as a dust separation device, and the size of the dust accommodation space of the second collection part is variable and includes a dust bag made of a breathable material as a dust separation device.

[0020] The vacuum cleaner base station may further include a compression driving part disposed outside the collection part accommodation space to generate power for rotating a compression rotating part for compressing dust collected inside the first collection part.

[0021] The vacuum cleaner base station may distinguish the type of the collection part currently coupled to the chamber part based on the operation mode of the compression driving part.

[0022] The compression driving part may include: a compression motor disposed outside the collection part accommodation space; and a driving gear axially connected to the compression motor outside the collection part accommodation space to transmit the power generated by the compression motor to the compression rotating part.

[0023] The first collection part may include a transmission gear that is coupled to the compression rotating part to transmit power from the compression driving part to the compression rotating part.

[0024] A gear through-hole may be formed in the lower part of the chamber part, and at least a part of the compression driving part is exposed toward the inside of the trapping part accommodation space through the gear through-hole.

[0025] The vacuum cleaner base station may further include a control unit configured to sense a change in the rotation direction of the compression driving part.

[0026] The control unit may determine the type of the trapping part coupled to the chamber part based on whether a change in the rotation direction of the compression driving part is sensed within a preset time.

[0027] Before the dust collection motor is driven after the trapping part is coupled to the chamber part, the compression driving part may rotate for a preset time.

[0028] If the rotation direction of the compression driving part changes in the opposite direction within the preset time, the vacuum cleaner base station may determine that the first trapping part is coupled to the chamber part.

[0029] If the rotation direction of the compression driving part remains the same after the preset time has elapsed, the vacuum cleaner base station may determine that the second trapping part is coupled to the chamber part.

[0030] The vacuum cleaner base station drives the compression driving part only after the dust collection motor is driven when the first trapping part is coupled to the chamber part.

[0031] Advantages of the Invention

[0032] According to the present invention, a user can use one of a first trapping part and a second trapping part by coupling it to the vacuum cleaner base station. The first trapping part has a bucket shape with a fixed size of a dust accommodation space, and the second trapping part has a bag shape with a variable size of the dust accommodation space. Therefore, it has the advantage of being able to satisfy various preferences of users who like different types of trapping parts.

[0033] In addition, according to the present invention, since the trapping part currently coupled to the vacuum cleaner base station can be distinguished, the vacuum cleaner base station can be efficiently driven according to the shape of the trapping part.

[0034] In addition, according to the present invention, the trapping part can be distinguished by using the compression driving part provided for compressing dust, without additionally providing a sensor.

[0035] The advantages of the present invention are not limited to the above-mentioned advantages, and those skilled in the art can clearly understand other advantages not mentioned from the following description of the specific content for implementing the present invention.

[0072] Figure 1 It is a diagram for explaining the vacuum cleaner in an embodiment of the present invention. Figure 2 It is viewed from different angles Figure 1 of the vacuum cleaner. Figure 3 It is a diagram for explaining the lower side of the dust bin of the vacuum cleaner in an embodiment of the present invention. Figure 4 It is a diagram for explaining the vacuum cleaner system in an embodiment of the present invention.

[0073] Referring to Figures 1 to 4 the vacuum cleaner system 3 according to an embodiment of the present invention may include a vacuum cleaner 200 and a vacuum cleaner base station 300.

[0074] The vacuum cleaner system 3 may include a vacuum cleaner base station 300. The vacuum cleaner 200 may be combined with the vacuum cleaner base station 300. The vacuum cleaner 200 may be combined with the side of the vacuum cleaner base station 300. The vacuum cleaner base station 300 may remove the dust from the dust bin 220 of the vacuum cleaner 200.

[0075] First, referring to Figures 1 to 3 the structure of the vacuum cleaner 200 will be described as follows.

[0076] The vacuum cleaner 200 may refer to a vacuum cleaner manually operated by a user. For example, the vacuum cleaner 200 may refer to a handheld vacuum cleaner or a stick vacuum cleaner.

[0077] The vacuum cleaner 200 may be placed on the vacuum cleaner base station 300. The vacuum cleaner 200 may be supported by the vacuum cleaner base station 300. The vacuum cleaner 200 may be combined with the vacuum cleaner base station 300.

[0078] On the other hand, in an embodiment of the present invention, the direction of the vacuum cleaner 200 may be defined based on the case where the dust bin 220 and the bottom surface (lower side surface) of the battery cover 230 are placed on the ground.

[0079] At this time, the front may refer to the direction in which the suction part 212 is arranged based on the suction motor 214, and the rear may refer to the direction in which the handle 216 is arranged based on the suction motor 214. Also, the direction arranged on the right side based on the case of observing the suction part 212 from the suction motor 214 may be called the right side, and the direction arranged on the left side may be called the left side. In addition, in an embodiment of the present invention, the direction perpendicular to the ground based on the case where the bottom surface (lower side surface) of the dust bin 220 and the battery cover 230 are placed on the ground may be defined as the upper side and the lower side.

[0080] The vacuum 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.

[0081] The main body cover 211 may form the appearance of the vacuum cleaner 200. The main body cover 211 may provide a space capable of accommodating the suction motor 214 and a filter (not shown) inside. The main body cover 211 may be configured in a shape similar to a cylinder.

[0082] The suction part 212 may protrude outward from the main body cover 211. As an example, the suction part 212 may be formed in a cylindrical shape with an open interior. The suction part 212 may be coupled to an extension pipe 250. The suction part 212 may provide a flow path (hereinafter, may be referred to as "suction flow path") through which air containing dust can flow.

[0083] The dust separation part 213 may communicate with the suction part 212. The dust separation part 213 may separate the dust sucked into the interior through the suction part 212. The space inside the dust separation part 213 may communicate with the space inside the dust bin 220.

[0084] For example, the dust separation part 213 may have at least one cyclone part capable of separating dust by a cyclone flow. And the space inside the dust separation part 213 may communicate with the suction flow path. Therefore, the air and dust sucked through the suction part 212 may flow spirally along the inner circumferential surface of the dust separation part 213. Therefore, a cyclone flow may be generated in the inner space of the dust separation part 213.

[0085] The dust separation part 213 is a configuration that communicates with the suction part 212 and applies the dust collector principle using centrifugal force in order to separate the dust sucked into the interior of the main body 210 through the suction part 212.

[0086] The dust separation unit 213 may further include a secondary cyclone that separates dust again from the air discharged from the cyclone. At this time, the secondary cyclone may be located inside the cyclone to minimize the size of the dust separation unit. The secondary cyclone may include a plurality of cyclone bodies arranged in parallel. The air discharged from the cyclone may flow through the plurality of cyclone bodies respectively.

[0087] At this time, the axis of the cyclone flow of the secondary cyclone may also extend in the vertical direction, and the axis of the cyclone flow of the cyclone and the axis of the cyclone flow of the secondary cyclone may be coaxial in the vertical direction, which may be collectively referred to as the axis of the cyclone flow of the dust separation unit 213.

[0088] The suction motor 214 may generate a suction force for sucking air. The suction motor 214 may be accommodated in the main body cover 211. The suction motor 214 may generate a suction force by rotation. As an example, the suction motor 214 may have a shape similar to a cylinder.

[0089] The air discharge cover 215 may be disposed on one axial side of the main body cover 211. A filter for filtering air may be accommodated in the air discharge cover 215. As an example, a high-efficiency particulate air (HEPA) filter may be accommodated in the air discharge cover 215.

[0090] An air discharge port for discharging the air sucked by the suction force of the suction motor 214 may be formed in the air discharge cover 215.

[0091] A flow guide member may be disposed in the air discharge cover 215. The flow guide member may guide the flow of the air discharged through the air discharge port.

[0092] The handle 216 may be held by the user. The handle 216 may be disposed behind the suction motor 214. As an example, the handle 216 may be formed in a shape similar to a cylinder. Or, the handle 216 may be formed in a curved cylindrical shape. The handle 216 may form a predetermined angle with the main body cover 211 or the suction motor 214 or the dust separation unit 213.

[0093] The handle 216 may include: a grip portion 216a formed in a column shape so that the user can hold it; a first extension portion 216b connected to one end portion in the length direction (axial direction) of the grip portion 216a and extending toward the suction motor 214; and a second extension portion 216c connected to the other end portion in the length direction (axial direction) of the grip portion 216a and extending toward the dust bin 220.

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

[0095] The first extension part 216b can extend from the holding part 216a towards the body cover 211 or the suction motor 214. At least a part of the first extension part 216b can extend in the horizontal direction.

[0096] The second extension part 216c can extend from the holding part towards the dust bin 220. At least a part of the second extension part 216c can extend in the horizontal direction.

[0097] The operation part 218 can be arranged on the handle 216. The operation part 218 can be arranged on the inclined surface formed in the upper area of the handle 216. The user can input the operation or stop command of the vacuum cleaner 200 through the operation part 218.

[0098] The vacuum cleaner 200 can include a dust bin 220. The dust bin 220 can communicate with the dust separation part 213. The dust bin 220 can store the dust separated from the dust separation part 213.

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

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

[0101] A part of the lower side surface (bottom surface) of the dust bin body 221 can be open. In addition, a bottom surface extension part 221a can be formed on the lower side surface (bottom surface) of the dust bin body 221. The bottom surface extension part 221a can be formed to block a part of the lower side surface of the dust bin body 221.

[0102] The dust bin 220 can include a discharge cover 222. The discharge cover 222 can be arranged on the lower side surface of the dust bin 220.

[0103] The discharge cover 222 can be set to open and close one end of the dust bin body 221 in the length direction. Specifically, the discharge cover 222 can selectively open and close the lower part of the dust bin 220 that opens downward.

[0104] The discharge cover 222 can include a cover body 222a and a hinge part 222b. The cover body 222a can be formed to block a part of the lower side surface of the dust bin body 221. The cover body 222a can rotate downward with the hinge part 222b as a reference. The hinge part 222b can be arranged adjacent to the battery cover 230. A torsion spring 222d can be arranged on the hinge part 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 can be supported in a state of rotating more than a specified angle around the hinge part 222b in the dust bin body 221.

[0105] The discharge cover 222 can be coupled to the dust bin 220 by hook coupling. On the other hand, the discharge cover 222 can be separated from the dust bin 220 by a coupling rod 222c. The coupling rod 222c can be disposed in front of the dust bin. Specifically, the coupling rod 222c can be disposed on the front side outer surface of the dust bin 220. When an external force is applied, the coupling rod 222c can elastically deform the hook formed by extending the cover body 222a to release the hook coupling between the cover body 222a and the dust bin body 221.

[0106] When the discharge cover 222 is in a closed state, the lower side of the dust bin 220 can be blocked (sealed) by the discharge cover 222 and the bottom surface extension 221a.

[0107] The dust bin 220 can include a dust bin compression rod 223 (refer to Figure 2 ). The dust bin compression rod 223 can be disposed outside the dust bin 220 or the dust separation unit 211. The dust bin compression rod 223 can be disposed movably up and down outside the dust bin 220 or the dust separation unit 213. The dust bin compression rod 223 can be connected to a compression member (not shown). When the dust bin compression rod 223 is moved downward by an external force, the compression member (not shown) can also move downward together. Thereby, user convenience can be provided. The compression member (not shown) and the dust bin compression rod 223 can be reset to their original positions by an elastic member (not shown). Specifically, when the external force applied to the dust bin compression rod 223 is released, the elastic member can move the dust bin compression rod 223 and the compression member (not shown) upward.

[0108] The compression member (not shown) can be disposed inside the dust bin body 221. The compression member can move in the internal space of the dust bin body 221. Specifically, the compression member can move up and down inside the dust bin body 221. Thereby, the compression member can 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 part of the dust bin 220 is opened, the compression member moves from the upper part to the lower part of the dust bin 220, so that foreign matters such as remaining dust in the dust bin 220 can be removed. Thereby, the suction force of the vacuum cleaner can be improved by preventing the remaining dust from remaining in the dust bin 220. Further, by preventing the remaining dust from remaining in the dust bin 220, the odor generated by the residue can be removed.

[0109] The vacuum cleaner 200 can include a battery cover 230. The battery 240 can be accommodated in the battery cover 230. The battery cover 230 can be disposed below the handle 216. As an example, the battery cover 230 can be a hexahedron shape with an open bottom. The back surface of the battery cover 230 can be connected to the handle 216.

[0110] The battery cover 230 may include a receiving portion that is open downward. The battery 240 can be loaded and unloaded through the receiving portion of the battery cover 220.

[0111] The vacuum cleaner 200 may include a battery 240.

[0112] For example, the battery 240 may be detachably coupled to the 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 interior of the battery cover 230 from below the battery cover 230. With this configuration, the portability of the vacuum cleaner 200 can be improved.

[0113] Alternatively, the battery 240 may be integrally provided with the battery cover 230 inside the battery cover 230. At this time, the bottom surface of the battery 240 is not exposed to the outside.

[0114] The battery 240 may supply power to the suction motor 214 of the vacuum cleaner 200. The battery 240 may be disposed below the handle 216. The battery 240 may be disposed behind the dust bin 220.

[0115] According to an embodiment, when the battery 240 is coupled to the battery cover 230, the bottom surface of the battery 240 may be exposed to the outside. When the vacuum cleaner 200 is placed on the floor surface, the battery 240 may be placed on the floor, so the battery 240 can be directly separated from the battery cover 230. In addition, since the bottom surface of the battery 240 is exposed to the outside and is in direct contact with the outside air of the battery 240, the cooling performance of the battery 240 can be improved.

[0116] On the other hand, when the battery 240 is integrally fixed to the battery cover 230, the structure for loading and unloading the battery 240 and the battery cover 230 can be reduced, so the overall size of the vacuum cleaner 200 can be reduced and weight reduction can be achieved.

[0117] The vacuum cleaner 200 may include an extension tube 250. The extension tube 250 may communicate with the cleaning module 260. The extension tube 250 may communicate with the main body 210. The extension tube 250 may communicate with the suction portion 212 of the main body 210. The extension tube 250 may be formed in a long cylindrical shape.

[0118] 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 a suction force through the suction motor 214, and may provide the suction force 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.

[0119] The vacuum cleaner 200 may include a cleaning module 260. The cleaning module 260 may communicate with the extension pipe 250. Accordingly, external air may flow into the main body 210 of the vacuum cleaner 200 through the cleaning module 260 and the extension pipe 250 by the suction force generated in the main body 210 of the vacuum cleaner 200.

[0120] The dust in the dust bin 220 of the vacuum cleaner 200 may be trapped by gravity in the trapping unit 500 of the vacuum cleaner base station 300. At the same time, the dust in the dust bin 220 may be trapped by the suction force of the dust collection motor 391 disposed inside the vacuum cleaner base station 300 in the trapping unit 500 of the vacuum cleaner base station 300. Accordingly, the dust in the dust bin of the vacuum cleaner may be removed without additional operation by the user, thereby improving user convenience. In addition, the trouble of the user emptying the dust bin every time may be eliminated. In addition, scattering of dust when emptying the dust bin may be prevented.

[0121] The vacuum cleaner 200 may be coupled to the side of the cover body 310. Specifically, the main body 210 of the vacuum cleaner 200 may be placed on the coupling part 320. More specifically, the dust bin 220 and the battery cover body 230 of the vacuum cleaner 200 may be coupled to the coupling surface 321 of the coupling part 320. The outer circumferential surface of the dust bin main body 221 may be coupled to the dust bin guide surface 322. The suction part 212 may be coupled to the suction part guide surface 326 of the coupling part 320. With this configuration, the central axis of the dust bin 220 may be disposed in a direction parallel to the ground, and the extension pipe 250 may be disposed in a direction perpendicular to the ground.

[0122] Hereinafter, the configuration of the vacuum cleaner base station 300 according to an embodiment of the present invention will be described.

[0123] Refer to Figure 4 , the vacuum cleaner 200 may be coupled to the vacuum cleaner base station 300. Specifically, the main body of the vacuum cleaner 200 may be coupled to the side of the vacuum cleaner base station 300. More specifically, the dust bin 220 of the vacuum cleaner 200 may be coupled to the side of the vacuum cleaner base station 300, and may be coupled through one side where the discharge cover 222 is disposed. Accordingly, if the discharge cover 222 is opened, the dust in the dust bin 220 may be trapped inside the vacuum cleaner base station 300 to be removed.

[0124] The vacuum cleaner base station 300 may include a cover body 310. The cover body 310 may form the appearance of the vacuum cleaner base station 300. Specifically, the cover body 310 may be formed in a column shape including at least one outer wall surface. As an example, the cover body 310 may be formed in a shape similar to a quadrangular prism.

[0125] The cover body 310 may form a space inside capable of accommodating the trapping unit 500 and the dust suction module 390.

[0126] The cover body 310 may include a bottom surface 311, an outer wall surface 312, and an upper surface 313.

[0127] The bottom surface 311 may support the lower side in the gravity direction of the dust suction module 390. That is, the bottom surface 311 may support the lower side of the dust collecting motor 391 of the dust suction module 390.

[0128] At this time, the bottom surface 311 may be arranged facing the ground. The bottom surface 311 may be arranged parallel to the ground, and of course, it may also be arranged at a specified angle inclined to the ground. With this configuration, there is an advantage that the dust collecting motor 391 can be stably supported, and the overall weight can be balanced even when the vacuum cleaner 200 is combined.

[0129] On the other hand, according to an embodiment, the bottom surface 311 may further include a bottom surface support portion 311a, and the bottom surface support portion 311a increases the contact area with the ground to prevent the vacuum cleaner base station 300 from tipping over and maintain balance. As an example, the bottom surface support portion 311a may be a plate shape extending from the bottom surface 311, or one or more frames may protrude and extend along the ground direction on the bottom surface 311.

[0130] The outer wall surface 312 may refer to the surface formed in the gravity direction and may refer to the surface connected to the bottom surface 311. For example, the outer wall surface 312 may refer to the surface perpendicularly connected to the bottom surface 311. As a different embodiment, the outer wall surface 312 may also be arranged at a specified angle inclined to the bottom surface 311.

[0131] The outer wall surface 312 may include at least one surface. As an example, the outer wall surface 312 may include a first outer wall surface 312a, a second outer wall surface 312b, a third outer wall surface 312c, and a fourth outer wall surface 312d.

[0132] At this time, in this embodiment, the first outer wall surface 312a may be arranged on the front of the vacuum cleaner base station 300. Here, the front may refer to the surface where the vacuum cleaner 200 is exposed in the state where the vacuum cleaner 200 is combined with the vacuum cleaner base station 300. Therefore, the first outer wall surface 312a may form the appearance of the front of the vacuum cleaner base station 300.

[0133] On the other hand, for understanding this embodiment, the definition of directions is as follows. In this embodiment, directions may be defined in the state where the vacuum cleaner 200 is combined with the vacuum cleaner base station 300.

[0134] When the vacuum cleaner 200 is combined with the vacuum cleaner base station 300, the direction in which the vacuum cleaner 200 is exposed to the outside of the vacuum cleaner base station 300 may be called the front.

[0135] From another perspective, the direction in which the suction motor 214 of the vacuum cleaner 200 is disposed when the vacuum cleaner 200 is combined with the vacuum cleaner base 300 can be referred to as the front. And, the opposite direction of the direction in which the suction motor 214 is disposed in the vacuum cleaner base 300 can be referred to as the rear.

[0136] And, the surface of the direction opposite to the front with respect to the internal space of the cover 310 can be referred to as the back surface of the vacuum cleaner base 300. Therefore, the back surface can refer to the direction in which the second outer wall surface 312b is formed.

[0137] And, the surface on the left side when observing the front surface with respect to the internal space of the cover 310 can be referred to as the left surface, and the surface on the right side can be referred to as the right surface. Therefore, the left surface can refer to the direction in which the third outer wall surface 312c is formed, and the right surface can refer to the direction in which the fourth outer wall surface 312d is formed.

[0138] The first outer wall surface 312a can be formed in a planar shape. Of course, it can also be formed in a curved surface shape as a whole, or can be formed including a curved surface in part.

[0139] The coupling part 320 can be disposed on the first outer wall surface 312a. With this configuration, the vacuum cleaner 200 can be coupled to the vacuum cleaner base 300 and can be supported by the vacuum cleaner base 300. The specific configuration of the coupling part 320 will be described later.

[0140] On the other hand, a structure for additionally placing various types of cleaning modules 260 for the vacuum cleaner 200 can also be added to the first outer wall surface 312a.

[0141] In this embodiment, the second outer wall surface 312b can be a surface opposite to the first outer wall surface 312a. That is, the second outer wall surface 312b can be disposed on the back surface of the vacuum cleaner base 300. The second outer wall surface 312b can form the appearance of the back surface of the vacuum cleaner base 300.

[0142] In this embodiment, the third outer wall surface 312c and the fourth outer wall surface 312d can refer to the surfaces connecting the first outer wall surface 312a and the second outer wall surface 312b. At this time, the third outer wall surface 312c can be disposed on the left side of the vacuum cleaner base 300, and the fourth outer wall surface 312d can be disposed on the right side of the vacuum cleaner base 300. Differently, it can also be that the third outer wall surface 312c is disposed on the right side of the vacuum cleaner base 300, and the fourth outer wall surface 312d is disposed on the left side of the vacuum cleaner base 300.

[0143] The third outer wall surface 312c or the fourth outer wall surface 312d is formed in a planar shape. Of course, it can also be formed in a curved surface shape as a whole, or can be formed including a curved surface in part.

[0144] On the other hand, a structure for mounting various types of cleaning modules 290 for the vacuum cleaner 200 may also be added to the third outer wall surface 312c or the fourth outer wall surface 312d.

[0145] The upper surface 313 may form the upper appearance of the vacuum cleaner base station. That is, the upper surface 313 may refer to the surface that is disposed on the uppermost side in the direction of gravity and exposed to the outside in the vacuum cleaner base station.

[0146] As a reference, in the present embodiment, the upper side and the lower side may respectively refer to the upper side and the lower side in the direction of gravity (the direction perpendicular to the ground) when the vacuum cleaner base station 300 is disposed on the ground.

[0147] At this time, the upper surface 313 may be disposed parallel to the ground. Of course, it may also be disposed at a predetermined angle inclined to the ground.

[0148] A display unit 730 may be disposed on the upper surface 313. As an example, the display unit 730 may display the status of the vacuum cleaner base station 300 and the status of the vacuum cleaner 200. In addition, it may also display information such as the cleaning progress and the map of the cleaning area.

[0149] On the other hand, according to an embodiment, the upper surface 313 may be detachably provided with respect to the outer wall surface 312. At this time, when the upper surface 313 is separated, a battery separated from the vacuum cleaner 200 may be accommodated in the internal space surrounded by the outer wall surface 312, and terminals (not shown) capable of charging the separated battery may be provided.

[0150] Figure 5 It is a diagram for explaining the coupling part of the vacuum cleaner base station in the embodiment of the present invention.

[0151] Refer to Figure 5 , the vacuum cleaner base station 300 may include a coupling part 320 for coupling the vacuum cleaner 200. Specifically, the coupling part 320 is disposed on the first outer wall surface 312a and can couple the dust bin 220 of the vacuum cleaner 200. Together with the dust bin 220, the body 210 and the battery cover 230 of the vacuum cleaner 200 may also be coupled to the coupling part 320.

[0152] The coupling part 320 may include a coupling surface 321. The coupling surface 321 may be disposed on the side surface of the cover body 310. As an example, the coupling surface 321 may refer to a groove-shaped surface that is recessed from the first outer wall surface 312a toward the inside of the vacuum cleaner base station 300. That is, the coupling surface 321 may refer to a surface that forms a step with the first outer wall surface 312a.

[0153] The vacuum cleaner 200 can be coupled to the coupling surface 321. As an example, the coupling surface 321 can be in contact with the lower side surfaces of the dust bin 220 and the battery cover 230 of the vacuum cleaner 200. Here, the lower side surface can refer to the surface facing the ground when the user uses the vacuum cleaner 200 or places the vacuum cleaner 200 on the ground.

[0154] As an example, the angle formed by the coupling surface 321 and the ground can be a right angle. Thus, when the vacuum cleaner 200 is coupled to the coupling surface 321, the space of the vacuum cleaner base 300 can be minimized.

[0155] As another example, the coupling surface 321 can be inclined at a specified angle with respect to the ground. Thus, when the vacuum cleaner 200 is coupled to the coupling surface 321, the vacuum cleaner base 300 can be stably supported.

[0156] A dust through-hole 321a can be formed in the coupling surface 321 to allow air outside the cover 310 to flow into the interior. The dust through-hole 321a can be formed in a hole shape corresponding to the shape of the dust bin 220 so that the dust in the dust bin 220 can flow into the collection unit 500. The dust through-hole 321a can be formed corresponding to the shape of the discharge cover 222 of the dust bin 220. The dust through-hole 321a can be formed to communicate with a later-described flow path portion 380 (refer to Figure 8 ).

[0157] The coupling portion 320 can include a dust bin guide surface 322. The dust bin guide surface 322 can be disposed on the first outer wall surface 312a. The dust bin guide surface 322 can be connected to the first outer wall surface 312a. Additionally, the dust bin guide surface 322 can be connected to the coupling surface 321.

[0158] The dust bin guide surface 322 can be formed in a shape corresponding to the outer side surface of the dust bin 220. The front outer side surface of the dust bin 220 can be coupled to the dust bin guide surface 322. Thus, it can provide convenience for the vacuum cleaner 200 to be coupled to the coupling surface 321.

[0159] On the other hand, a convex moving hole 322a can be formed in the dust bin guide surface 322, and a later-described push protrusion 351 can linearly move along the convex moving hole 322a (refer to Figure 9)。In addition, a gear box 355 for accommodating gears and the like of the lid opening unit 350 described later can be provided on the lower side in the direction of gravity of the dust bin guide surface 322. At this time, a guide space 322b capable of moving the push projection 351 can be formed between the dust bin guide surface 322, the lower side surface, and the upper side surface of the gear box 355. And, the guide space 322b can communicate with the first flow path 381 through a side through hole 322c. That is, the projection movement hole 322a, the guide space 322b, the side through hole 322c, and the first flow path 381 can form a flow path. With this configuration, when the dust collection motor 391 operates in a state where the dust bin 220 is coupled to the coupling portion 320, the dust and the like remaining in the dust bin 220 and the dust bin guide surface 322 can be sucked through the flow path.

[0160] The coupling portion 320 may include guide projections 323. The guide projections 323 may be disposed on the coupling surface 321. The guide projections 323 may protrude upward from the coupling surface 321. Two guide projections 323 may be disposed at intervals from each other. The distance between the two guide projections 323 disposed at intervals from each other may correspond to the width of the battery cover 230 of the vacuum cleaner 200. Thereby, it is possible to provide convenience for the vacuum cleaner 200 to be coupled to the coupling surface 321.

[0161] The coupling portion 320 may include coupling portion side walls 324. The coupling portion side walls 324 may refer to wall surfaces disposed on both side surfaces of the coupling surface 321 and may be vertically connected to the coupling surface 321. The coupling portion side walls 324 may be connected to the first outer wall surface 312a. In addition, the coupling portion side walls 324 may form a surface connected to the dust bin guide surface 322. Thereby, the vacuum cleaner 200 can be stably accommodated.

[0162] The coupling portion 320 may include a coupling sensor. The coupling sensor may sense whether the vacuum cleaner 200 is coupled to the coupling portion 320.

[0163] The coupling sensor may also include a contact sensor. As an example, the coupling sensor may include a micro switch. At this time, the coupling sensor may be disposed on the guide projection 323. Therefore, if the battery cover 230 or the battery 240 of the vacuum cleaner 200 is coupled between a pair of guide projections 323, it will contact the coupling sensor, and the coupling sensor can sense that the vacuum cleaner 200 has been coupled.

[0164] On the other hand, the coupling sensor may also include a non-contact sensor. As an example, the coupling sensor may include an infrared sensor unit (IR sensor). At this time, the coupling sensor may be disposed on the side wall 324 of the coupling portion. Therefore, if the dust bin 220 or the main body 210 of the vacuum cleaner 200 reaches the coupling surface 321 through the side wall 324 of the coupling portion, the coupling sensor may sense the presence of the dust bin 220 or the main body 210.

[0165] In a state where the vacuum cleaner 200 is coupled to the vacuum cleaner base station 300, the coupling sensor may face the dust bin 220 or the battery cover 230 of the vacuum cleaner 200.

[0166] The coupling sensor may be a device that determines whether the vacuum cleaner 200 is coupled while power is being applied to the battery 240 of the vacuum cleaner 200.

[0167] The coupling portion 320 may include a suction portion guide surface 326. The suction portion guide surface 326 may be disposed on the first outer wall surface 312a. The suction portion guide surface 326 may be connected to the dust bin guide surface 322. The suction portion 212 may be coupled to the suction portion guide surface 326. The shape of the suction portion guide surface 326 may be formed to correspond to the shape of the suction portion 212.

[0168] The coupling portion 320 may further include a fixing member access hole 327. The fixing member access hole 327 may be formed in a long hole shape along the side wall 324 of the coupling portion to enable the fixing member 331 to enter and exit.

[0169] With this configuration, when the user couples the vacuum cleaner 200 to the coupling portion 320 of the vacuum cleaner base station 300, due to the dust bin guide surface 322, the guide protrusion 323, and the suction portion guide surface 326, the main body 210 of the vacuum cleaner 200 can be stably disposed in the coupling portion 320. Thereby, convenience in coupling the dust bin 220 and the battery cover 230 of the vacuum cleaner 200 to the coupling surface 321 can be provided.

[0170] On the other hand, the vacuum cleaner base station 300 may further include a charging terminal 328. The charging terminal 328 may be disposed in the coupling portion 320. The charging terminal 328 may be electrically connected to the vacuum cleaner 200 coupled to the coupling portion 320. The charging terminal 328 may supply power to the battery of the vacuum cleaner 200 coupled to the coupling portion 320.

[0171] In addition, the vacuum cleaner base station 300 may further include a side door. The side door may be disposed on the cover 310. The side door may selectively expose the collection unit 500 to the outside. Thus, the user can easily remove the collection unit 500 from the vacuum cleaner base station 300.

[0172] Figure 6It is a diagram for explaining the fixing unit of the vacuum cleaner base station in the embodiments of the present invention.

[0173] Referring to Figure 6 , the vacuum cleaner base station 300 of the present invention may include a fixing unit 330. The fixing unit 330 may be disposed on the side wall 324 of the joint portion. Additionally, the fixing unit 330 may be disposed inside the joint surface 321. The fixing unit 330 may fix the vacuum cleaner 200 coupled to the joint surface 321. Specifically, the fixing unit 330 may fix the dust bin 220 and the battery cover 230 of the vacuum cleaner 200 coupled to the joint surface 321.

[0174] The fixing unit 330 may include: a fixing member 331 that fixes the dust bin 220 and the battery cover 230 of the vacuum cleaner 200; and a fixing part motor 780 that drives the fixing member 331. Additionally, the fixing unit 330 may further include a fixing part link 335 that transmits the power of the fixing part motor 780 to the fixing member 331.

[0175] The fixing member 331 may be disposed on the side wall 324 of the joint portion and may be reciprocally movably provided on the side wall 324 of the joint portion to fix the dust bin 220. Specifically, the fixing member 331 may be accommodated inside the fixing member access hole 327.

[0176] The fixing members 331 may be respectively disposed on both sides of the joint portion 320. As an example, two fixing members 331 may be symmetrically paired with the joint surface 321 as the center.

[0177] The fixing part motor 780 may provide the power to move the fixing member 331.

[0178] The fixing part link 335 may convert the rotational force of the fixing part motor 780 into the reciprocating movement of the fixing member 331.

[0179] The fixing seal 336 may be disposed on the dust bin guide surface 322 to airtight the dust bin 220 when the vacuum cleaner 200 is coupled. With this configuration, when the dust bin 220 of the vacuum cleaner 200 is coupled, the fixing seal 336 may be pressed by the self-weight of the vacuum cleaner 200, and the dust bin 220 and the dust bin guide surface 322 may be sealed.

[0180] The fixing seal 336 may be disposed on the virtual extension line of the fixing member 331. With this configuration, when the fixing part motor 780 operates and the fixing member 331 presses the dust bin 220, the outer periphery of the dust bin 220 at the same height may be sealed.

[0181] According to an embodiment, the fixed seal 336 may be arranged in a linear form that can be bent corresponding to the configuration of the lid opening unit 350 described later on the dust bin guiding surface 322.

[0182] Therefore, when the main body 210 of the vacuum cleaner 200 is arranged at the coupling part 320, the fixing unit 330 can fix the main body 210 of the vacuum cleaner 200. Specifically, when it is sensed in the coupling sensor 325 that the main body 210 of the vacuum cleaner 200 is coupled to the coupling part 320 of the vacuum cleaner base 300, the fixing part motor 780 can fix the main body 210 of the vacuum cleaner 200 by moving the fixing member 331.

[0183] Thus, the suction force of the vacuum cleaner can be improved by preventing residual dust from remaining in the dust bin. Further, by preventing residual dust from remaining in the dust bin, the odor generated by the residue can be removed.

[0184] Figure 7 and Figure 8 are diagrams for explaining the relationship between the vacuum cleaner and the door unit in the vacuum cleaner base according to an embodiment of the present invention, Figure 7 is a diagram showing the state where the door closes the dust through-hole, Figure 8 is a diagram showing the state where the door opens the dust through-hole.

[0185] Referring to Figure 7 and Figure 8 , the vacuum cleaner base 300 of the present invention may include a door unit 340. The door unit 340 may be configured to be able to open and close the dust through-hole 321a.

[0186] The door unit 340 may include a door 341, a door motor 342, and a door arm 343.

[0187] The door 341 may be hinged to the coupling surface 321 and can open and close the dust through-hole 321a. The door 341 may include a door body 341a.

[0188] The door body 341a may be formed in a shape capable of blocking the dust through-hole 321a. As an example, the door body 341a may be formed in a shape similar to a disc.

[0189] Based on the state where the door body 341a blocks the dust through-hole 321a, a hinge part may be arranged on the upper side of the door body 341a, and an arm coupling part 341b may be arranged on the lower side of the door body 341a.

[0190] The door body 341a can be formed in a shape capable of airtight sealing of the dust through-hole 321a. As an example, the outer side surface of the door body 341a exposed to the outside of the vacuum cleaner base 300 is formed to have a diameter corresponding to the diameter of the dust through-hole 321a, and the inner side surface disposed inside the vacuum cleaner base 300 is formed to have a diameter larger than the diameter of the dust through-hole 321a. In addition, a step can be formed between the outer side surface and the inner side surface. On the other hand, at least one reinforcing rib can be convexly formed on the inner side surface, and the reinforcing rib connects the hinge portion and the arm coupling portion 341b to strengthen the supporting force of the door body 341a.

[0191] The hinge portion can be a means for hinge-coupling the door 341 to the coupling surface 321. The hinge portion can be disposed at the upper end portion of the door body 341a and coupled to the coupling surface 321.

[0192] The arm coupling portion 341b can be a means for rotatably coupling the door arm 343. The arm coupling portion 341b can be disposed at the lower side of the door body 341a, rotatably coupled to the door body 341a, and for rotatably coupling the door arm 343.

[0193] With this configuration, in a state where the door 341 closes the dust through-hole 321a, if the door arm 343 pulls the door body 341a, the door body 341a rotates and moves inwardly of the vacuum cleaner base 300 about the hinge portion, and the dust through-hole 321a can be opened. On the other hand, in a state where the dust through-hole 321a is open, if the door arm 343 pushes the door body 341a, the door body 341a rotates and moves outwardly of the vacuum cleaner base 300 about the hinge portion 341b, and the dust through-hole 321a can be blocked.

[0194] On the other hand, in a state where the vacuum cleaner 200 is coupled to the vacuum cleaner base 300 and the discharge cover 220 is separated from the dust bin body 210, the door 341 can contact the discharge cover 215. And as the door 341 rotates, the discharge cover 220 can rotate in linkage with the door 341.

[0195] The door motor 342 can provide power to rotate the door 341. Specifically, the door motor 342 can rotate the door arm 343 in the forward or reverse direction. Here, the forward direction can refer to the direction in which the door arm 343 pulls the door 341. Therefore, if the door arm 343 rotates in the forward direction, the dust through-hole 321a can be opened. In addition, the reverse direction can refer to the direction in which the door arm 343 pushes the door 341. Therefore, if the door arm 343 rotates in the reverse direction, at least a part of the dust through-hole 321a can be closed. The forward direction can be a direction opposite to the reverse direction.

[0196] The door arm 343 can connect the door 341 and the door motor 342, and can use the power generated in the door motor 342 to open and close the door 341.

[0197] As an example, the door arm 343 may include a first door arm 343a and a second door arm 343b. One end of the first door arm 343a may be combined with the door motor 342. The first door arm 343a may be rotated by the power of the door motor 342. The other end of the first door arm 343a may be rotatably combined with the second door arm 343b. The first door arm 343a may transmit the force transmitted from the door motor 342 to the second door arm 343b. One end of the second door arm 343b may be combined with the first door arm 343a. The other end of the second door arm 343b may be combined with the door 341. The second door arm 343b may open and close the dust through hole 321a by pushing or pulling the door 341.

[0198] The door unit 340 may be opened together with the discharge cover 222 of the cleaner 200. In addition, if the door unit 340 is closed, the discharge cover 222 of the cleaner 200 may be closed together with the door unit 340.

[0199] When removing dust from the dust bucket 220 of the vacuum cleaner 200, the door motor 342 can couple the discharge cover 222 to the dust bucket body 221 by rotating the door 341. Specifically, the door motor 342 can rotate the door 341 with the hinge part 341b as the reference by rotating the door 341, and the door 141 rotating with the hinge part 341b as the reference can push the discharge cover 222 toward the dust bucket body 221.

[0200] Figure 9 It is a figure for demonstrating the relationship between the vacuum cleaner and the lid opening unit in the Example of this invention.

[0201] Reference Figure 9 The vacuum cleaner base station 300 of the present invention may include a cover opening unit 350. The cover opening unit 350 may be disposed at the coupling portion 320, and may open the discharge cover 222 of the vacuum cleaner 200.

[0202] The cover opening unit 350 may include a push protrusion 351 , a cover opening motor 352 , a cover opening gear 353 , and a gear box 355 .

[0203] The push protrusion 351 may move in a manner of pressing the coupling rod 222 c when the cleaner 200 is coupled.

[0204] The push protrusion 351 may be disposed on the dust barrel guide surface 322. Specifically, a protrusion moving hole may be formed on the dust barrel guide surface 322, and the push protrusion 351 may be exposed to the outside through the protrusion moving hole.

[0205] The pushing protrusion 351 can be configured at a position where it can press the coupling rod 222c when the vacuum cleaner 200 is coupled. That is, the coupling rod 222c can be disposed on the protrusion moving hole. In addition, the coupling rod 222c can be disposed in the moving area of the pushing protrusion 351.

[0206] The pushing protrusion 351 can linearly reciprocate to press the coupling rod 222c. Specifically, the pushing protrusion 351 can be coupled to the gear box 355 to guide the linear movement. The pushing protrusion 351 can be coupled to the cover opening gear 353 and move together with the movement of the cover opening gear 353.

[0207] The cover opening motor 352 can provide the power to move the pushing protrusion 351. Specifically, the cover opening motor 352 can rotate the motor shaft in the forward or reverse direction. Here, the forward direction can refer to the direction in which the pushing protrusion 351 presses the coupling rod 222c. In addition, the reverse direction can refer to the direction in which the pushing protrusion 351 pressing the coupling rod 222c returns to its original position. The forward direction can be the direction opposite to the reverse direction.

[0208] The cover opening gear 353 is coupled to the cover opening motor 352 and can use the power of the cover opening motor 352 to move the pushing protrusion 351. Specifically, the cover opening gear 353 can be accommodated inside the gear box 355. The driving gear 353a of the cover opening gear 353 can be coupled to the motor shaft of the cover opening motor 352 to receive power. The driven gear 353b of the cover opening gear 353 can be coupled to the pushing protrusion 351 to move the pushing protrusion 351. As an example, the driven gear 353b can have a rack shape, mesh with the driving gear 353a, and receive power from the driving gear 353a.

[0209] At this time, a torsion spring 222d can be provided on the discharge cover 222. Due to the elastic force of the torsion spring 222d, the discharge cover 222 can rotate by more than a specified angle and can be supported at the rotated position. Therefore, the discharge cover 222 can be opened, and the dust through hole 321a can be communicated with the inside of the dust bin 220.

[0210] The gear box 355 can be disposed inside the housing 310, disposed below the coupling part 320 in the direction of gravity, and accommodate the cover opening gear 353 inside.

[0211] According to the present invention, due to the cover opening unit 350, the user can open the dust bin 220 without separately opening the discharge cover 222 of the vacuum cleaner, thereby improving convenience.

[0212] In addition, in a state where the vacuum cleaner 200 is coupled to the vacuum cleaner base station 300, the discharge cover 222 is opened, so there is an effect of preventing dust scattering.

[0213] Figure 10It is a diagram for explaining the configuration among the components of the vacuum cleaner base station in the embodiments of the present invention.

[0214] Refer to Figure 10 , the aforementioned lid opening unit 350 is disposed below the coupling part 320, and a flow path part 380 is disposed at the rear side of the coupling part 320 and the lid opening unit 350.

[0215] Hereinafter, the flow path from the coupling part 320 to the collection part 500 is referred to as the first flow path 381. The collection part 500 for collecting dust is configured to be connected to the lower end of the first flow path 381.

[0216] The vacuum cleaner base station 300 may further include a chamber part 360.

[0217] The chamber part 360 is disposed in the cover body 310 and forms a collection part accommodation space 360a to accommodate the collection part 500.

[0218] At this time, the collection part 500 may be detachably provided in the chamber part 360. The chamber part 360 may be a configuration detachably provided in the cover body 310 or a configuration integrally formed with the cover body 310. The detailed structure of the chamber part 360 will be described Figure 11 afterwards.

[0219] The vacuum cleaner base station 300 may include a flow path part 380.

[0220] The flow path part 380 is defined as a passage for the air and foreign matters flowing out of the dust bin 220 of the vacuum cleaner 200 to flow. The flow path part 380 may include: a first flow path 381, connecting the dust bin 220 and the collection part 500; and a second flow path 382, connecting the collection part 500 and the dust collection motor 391.

[0221] The first flow path 381 may be disposed at the rear side of the joint surface 321. The first flow path 381 may refer to a space formed for air to flow between the dust bin 220 of the vacuum cleaner 200 and the collection part 500. For example, the first flow path 381 may be a space surrounded by a structure. For example, the first flow path 381 may be the internal space of a hollow tube.

[0222] The first flow path 381 may include: a first area 381a, which is communicated with the internal space of the dust bin 220 when the vacuum cleaner 200 is combined with the vacuum cleaner base station 300 and the dust through hole 321a is opened; and a second area 381b, communicating the first area 381a and the collection part 500. (Refer to Figure 8 )

[0223] Therefore, if the dust collection motor 391 operates, the dust in the dust bin 220 of the vacuum cleaner 200 can flow to the collection part 500 through the first flow path 381.

[0224] The second flow path 382 can connect the trapping unit 500 and the dust suction module 390. That is, the air from which dust has been separated while passing through the trapping unit 500 can be guided to the dust collecting motor 391 through the second flow path 382.

[0225] The second flow path 382 can refer to a space formed for air to flow between the trapping unit 500 and the dust suction module 390. The second flow path 382 can be formed by being surrounded by structures.

[0226] In an embodiment where the trapping unit 500 is the first trapping unit 510, a partial area of the second flow path 382 can be formed inside the first trapping unit 510. The partial area can be referred to as the discharge flow path 518. The discharge flow path 518 can be disposed on the front side of the trapping unit main body 511 (refer to Figure 24 , Figure 26 ).

[0227] The vacuum cleaner base station 300 can include a dust suction module 390.

[0228] Referring again to Figure 10 , the dust suction module 390 can include a dust collecting motor 391. The dust collecting motor 391 can be disposed below the trapping unit 500. The dust collecting motor 391 can generate a suction force on the flow path unit 380. Thereby, a suction force capable of sucking dust into the dust bin 220 of the vacuum cleaner 200 is provided.

[0229] The dust suction module 390 can further include a high-efficiency air filter (not shown). The high-efficiency air filter can be disposed at the rear end of the dust collecting motor 391 (based on the air flow path). Thereby, clean air flows out to the outside of the cover body 310.

[0230] On the other hand, although not shown in Figure 10 , the fixing unit 330 and the door unit 340 can be disposed adjacent to the coupling unit 320, which has been described above with reference to Figures 6 to 8 .

[0231] The vacuum cleaner base station 300 can further include a trapping unit 500.

[0232] Figure 11 FIG. is a perspective view showing a chamber unit 360 and a trapping unit 500 in a form that can be coupled to the chamber unit 360 in an embodiment of the present invention.

[0233] The trapping unit 500 can be detachably coupled to the chamber unit 360. A dust accommodation space is provided in the trapping unit 500 to be able to collect the dust sucked from the inside of the dust bin 220 by the dust collecting motor 391.

[0234] On the other hand, the collection unit 500 of the embodiment of the present invention may be a first collection unit 510 in the form of a bucket with a fixed size of the dust accommodation space.

[0235] The first collection unit 510 has the form of a "bucket", so it is easy to clean the inside. As long as the contained dust is removed, it can be used semi-permanently. However, users may find it troublesome to remove and clean the dust, which is a task that needs to be performed separately.

[0236] Alternatively, the collection unit 500 of the embodiment of the present invention may be a second collection unit 520 in the form of a bag with a variable size of the dust accommodation space.

[0237] The second collection unit 520 is usually formed of a breathable material that allows air to flow out but does not allow dust to flow out. Even if the contained dust is removed, the inside of the second collection unit 520 cannot be cleaned. Therefore, there is a problem that it needs to be purchased and replaced periodically. However, it has a simple structure and there is no need to separately remove dust or clean its inside. The entire second collection unit 520 can be thrown into the trash can, which has an advantage in terms of user convenience.

[0238] The vacuum cleaner base station 300 of the embodiment of the present invention can operate even if any one of the two forms of collection units 510 and 520 is accommodated in the collection unit accommodation space 360a of the chamber unit 360. That is, the two forms of collection units 510 and 520 can be interchanged.

[0239] Considering the advantages and disadvantages of each of the above collection units 510 and 520 and their own preferences, users can choose the collection units 510 and 520 to be used.

[0240] The advantage of interchangeability is not limited to the scope of user preferences. For example, it also has the advantage that users who prefer the first collection unit 510 can temporarily use the second collection unit 520 during the drying process after cleaning the first collection unit 510.

[0241] Therefore, various features provided in the chamber unit 360 in such a way that the collection units 510 and 520 of different forms can be interchanged with each other will be described.

[0242] Figure 12 It is a cross-sectional view of the chamber unit 360 in the embodiment of the present invention observed from the side, Figure 13 It is an enlarged cross-sectional view of the upper side of the chamber unit 360 in the embodiment of the present invention, Figure 14 It is a view of the chamber unit 360 in the embodiment of the present invention observed from the front, Figure 15 It is a perspective view showing the internal structure of the chamber unit 360 in the embodiment of the present invention, Figure 16 It is a cross-sectional view showing the compression driving unit 362 in the embodiment of the present invention.

[0243] First, referring back again to Figure 11 the chamber part 360 may include a chamber body 361.

[0244] The chamber body 361 forms the exterior of the trapping part accommodation space 360a. The trapping part accommodation space 360a may be in a generally hexahedral shape.

[0245] One side of the chamber body 361 may be open. The open side of the chamber body 361 may be the front. The open side of the chamber body 361 may be closed by a cover 370.

[0246] One side of the cover 370 may be rotatably coupled to one side of the cover body 300. If the other side of the cover 370 rotates away from the cover body 300, one side of the chamber body 361 is opened. On the contrary, if the other side of the cover 370 rotates towards the cover body 300, one side of the chamber body 361 may be closed.

[0247] The trapping part accommodation space 360a formed by the chamber body 361 may be formed such that the cross-sectional area of the front end is larger than that of the rear end.

[0248] More specifically, referring to Figure 12 a virtual plane p1 connecting the front upper end and the rear upper end of the chamber body 361 may have a rear - downward inclination.

[0249] A virtual plane p2 connecting the front lower end and the rear lower end of the chamber body 361 may have a rear - upward inclination.

[0250] The upper side of the chamber body 361 has an inclination downward as it approaches the rear, and the lower side has an inclination upward as it approaches the rear, and the cross-sectional area of the front end of the trapping part accommodation space 360a is wider than that of the rear end.

[0251] With this structure, there is an advantage that the first trapping part 510 in a fixed form can be easily inserted into the trapping part accommodation space 360a.

[0252] An air inlet 3611 may be provided in the chamber body 361.

[0253] The air inlet 3611 allows the air flowing in through the first flow path 381 to pass through. The air inlet 3611 may be provided on the top surface of the chamber body 361. Alternatively, the air inlet 3611 may be provided at the end of a hollow tube integrally connected to the chamber body 361.

[0254] The air inlet 3611 is arranged vertically overlapping with the dust inlet of the trapping unit 500 described later. That is, the air and dust passing through the first flow path 381 flow into the dust accommodation space of the trapping unit 500 through the air inlet 3611 and the dust inlet in sequence.

[0255] An inlet seal member 367 may be arranged between the air inlet 3611 and the first flow path 381. The inlet seal member 367 prevents air and dust from leaking into the space outside the chamber body 361 by sealing the gap between the air inlet 3611 and the first flow path 381. The inlet seal member 367 may be arranged in a form surrounding the outer periphery of the air inlet 3611.

[0256] As described above, the chamber body 361 has a substantially downward sloping structure from the front upper end towards the rear upper end, and a sloping surface forming a rear-downward slope at a specified angle may be included in a partial area of the top surface of the chamber body 361.

[0257] The open cross-section of the air inlet 3611 formed in the upper part of the chamber body 361 may also slope downward from the front towards the rear.

[0258] The chamber body 361 may have an air outlet 3612.

[0259] The air outlet 3612 allows the air filtered while passing through the trapping unit 500 to pass through. The air outlet 3612 may be provided at the lower part of the chamber body 361. The air outlet 3612 may be provided at the lower end of the mounting wall of the filter mounting part 365 described later. (Refer to Figure 20 )

[0260] The air outlet 3612 is connected to the dust suction module 390. That is, the air passing through the air outlet 3612 can be finally discharged to the outside of the cover body via the dust suction module 390.

[0261] Refer to Figure 11 and Figure 15 , the chamber part 360 may include a compression driving part 362.

[0262] The compression driving part 362 is a component that generates power to rotate the compression rotating part 515 that compresses the dust collected in the first trapping part 510. The compression rotating part 515 will be described later.

[0263] The compression driving part 362 may be arranged at the lower part of the chamber body 361. More specifically, the compression driving part 362 may be arranged at the outer lower part of the chamber body 361.

[0264] Hereinafter, further referring to Figure 16 , the detailed structure of the compression driving part 362 will be described.

[0265] The compression driving unit 362 may include a compression motor 3622. The compression motor 3622 may be disposed outside the trapping unit accommodation space 360a. That is, the compression motor 3622 may be disposed outside the chamber body 361.

[0266] The compression motor 3622 generates power to rotate the compression rotating unit 515. The compression motor 3622 is a motor capable of forward and reverse rotation. In other words, the compression motor 3622 uses a motor capable of bidirectional rotation.

[0267] As described above, in order to enable the compression motor 3622 to rotate forward and reverse, the compression motor 3622 may use a synchronous motor. Such a synchronous motor is configured to be capable of forward and reverse rotation by the motor itself. When the force applied to the compression motor 3622 reaches a set value or more during the rotation of the compression motor 3622 in one direction, the rotation of the compression motor 3622 is switched to the other direction.

[0268] At this time, the force applied by the compression motor 3622 is the resistance (torque) generated when the rotating plate 5153 described later presses against another member (the fixing plate 5152 or the collected dust). When the resistance reaches a set value, the rotation direction of the compression motor 3622 is switched.

[0269] Other technologies related to the synchronous motor are well known in the motor technology field, and thus detailed description thereof is omitted.

[0270] The compression driving unit 362 may further include a driving gear 3621.

[0271] The driving gear 3621 rotates using the power of the compression motor 3622. For this purpose, the driving gear 3621 may be connected to the motor shaft of the compression motor 3622. The driving gear 3621 may be coupled to the upper side of the compression motor 3622.

[0272] The driving gear 3621 may be disposed outside the trapping unit accommodation space 360a. That is, the driving gear 3621 may be disposed outside the chamber body 361.

[0273] At this time, a part of the bottom surface of the chamber body 361 may protrude upward to form a driving gear accommodation portion 3613. (Refer to Figure 15 )

[0274] A gear through-hole 3613a is formed in the lower part of the chamber body 361 to expose at least a part of the drive gear 3621 toward the inside of the trapping part accommodation space 360a. More specifically, the side surface of the drive gear accommodation part 3613 may be penetrated to form the gear through-hole 3613a. The gear teeth 3621c of the drive gear 3621 may be exposed through the gear through-hole 3613a. (Refer to Figure 15 )

[0275] On the other hand, the drive gear 3621 and the compression motor 3622 are arranged outside the trapping part accommodation space 360a. Therefore, considering that the trapping part accommodation space 360a is a periodically opened space, it has the effect of preventing the drive gear 3621 and the compression motor 3622 from being exposed to contamination.

[0276] The drive gear 3621 can transmit rotational power to the compression rotating part 515.

[0277] The compression rotating part 515 is a concept including one or more components that rotate to compress the dust in the dust accommodation space collected in the first trapping part 510.

[0278] The detailed structure will be described later, including the operation of the rotating plate 5153 in the compression rotating part 515 rotating to collect dust. The rotating plate 5153 rotates in a manner close to the fixed plate 5152 fixed to one side of the first trapping part 510, so that the dust accumulated between the fixed plates 5152 can be pressed and compressed.

[0279] The first trapping part 510 may include a transmission gear 514.

[0280] The transmission gear 514 is a component combined with the compression rotating part 515, and can be arranged between the compression driving part 362 and the compression rotating part 515 to transmit rotational power.

[0281] More specifically, the transmission gear 514 may be arranged outside the lower part of the first trapping part 510. When the first trapping part 510 is inserted into the trapping part accommodation space 360a, the gear teeth 5142 of the transmission gear 514 may be engaged with the gear teeth 3621c of the drive gear 3621 exposed through the gear through-hole 3613a.

[0282] Thus, the rotational power generated by the compression motor 3622 can be transmitted to the compression rotating part 515 through the drive gear 3621 and the transmission gear 514.

[0283] On the other hand, the drive gear 3621 is received in the drive gear receiving portion 3613. The drive gear receiving portion 3613 is formed to protrude upward from the lowermost end surface of the collection portion accommodation space 360a. Therefore, by simply pushing the first collection portion 510 horizontally, the user can easily engage the transmission gear 514 and the drive gear 3621.

[0284] Referring to Figure 14 and Figure 15 , the chamber portion 360 may include a guide rail portion 363.

[0285] The guide rail portion 363 may be disposed at the upper part of the chamber body 361. More specifically, the guide rail portion 363 may be disposed at the upper inner part of the chamber body 361.

[0286] The guide rail portion 363 is configured such that at least a part of the second collection portion 520 is inserted and coupled thereto, and the second collection portion 520 can slide along the guide rail portion 363. The second collection portion 520 may be supported in a state separated from the bottom surface of the chamber body 361 and suspended from the guide rail portion 363.

[0287] As described above, the second collection portion 520 is a bag-type collection portion 500 in which the shape of the dust accommodation space is variable.

[0288] At this time, the dust bag 521 included in the second collection portion 520 expands by the suction drive of the dust collection motor 391, and dust flows into the inside of the dust bag 521 from the first flow path 381 due to the negative pressure formed by the expansion of the dust bag 521.

[0289] In an embodiment of the present invention, the dust bag 521, which is a component of the second collection portion 520, is made of a breathable material. That is, it is formed of a material that cannot let dust of a specified size or more flow out but can let air flow out. Therefore, as long as the suction drive of the dust collection motor 391 continues, dust will continue to be sucked into the inside of the dust bag 521.

[0290] When the dust bag 521 is in the state of maximum expansion and there is no separation distance between the lowermost end of the dust bag 521 and the inner bottom surface of the chamber body 361, the force for sucking dust will decrease. Therefore, it is preferable that there is a specified distance between the dust bag 521 and the bottom surface of the chamber body 361 even when the dust bag 521 is in the state of maximum expansion, so that the suction force can be evenly transmitted to the dust bag 521.

[0291] In an embodiment of the present invention, the guide rail portion 363 has a structure for separating and supporting the second collection portion 520 from the bottom surface of the chamber body 361, so that the first collection portion 510 and the second collection portion 520 can be interchanged.

[0292] The guide rail portion 363 may include a guide rail main body 3631.

[0293] Reference Figures 13 to 15 The guide rail body 3631 may form a space for the second collecting part 520 to slide. The guide rail body 3631 may be formed to extend from the front to the rear of the chamber body 361. The guide rail body 3631 may be disposed on the left and right sides, respectively. The guide rail body 3631 may be formed to have a left-right symmetrical structure.

[0294] The guide rail body 3631 may be open toward the center of the chamber body 361 and may have a shape similar to a "U" rotated 90 degrees. From another perspective, with the guide rail body 3631 disposed on the left side as a reference, the guide rail body 3631 may have a shape similar to the Korean letter "匚".

[0295] However, the above-mentioned shape of the guide rail body 3631 is merely an example, and the shape of the guide rail body 3631 may be changed to an appropriate structure capable of supporting the second collecting part 520 on the upper side of the chamber body 361 .

[0296] Similar to the top surface of the chamber body 361, the upper end surface of the guide rail body 3631 disposed on the top surface of the chamber body 361 may also be formed as an inclined surface. Different from this, the lower end surface of the guide rail body 3631 may be formed to be parallel to the ground. (See Figure 13 )

[0297] Below, refer to Figure 17 and Figure 18 , the detailed structure of the guide rail portion 363 is further explained.

[0298] Figure 17 yes Figure 15 The enlarged view of the "A" part, Figure 18 yes Figure 17 C-C' cross-sectional view.

[0299] and Figure 15 Refer to Figure 17 and Figure 18 , the guide rail portion 363 may further include an interference protrusion 3632 .

[0300] The interference protrusion 3632 may be disposed at a first position (Position 1 ) in front of the guide rail body 3631 where the interference protrusion 3632 interferes with the cover 370 .

[0301] More specifically, the first position may refer to a position that prevents the cover 370 from closing the open side of the chamber body 361 .

[0302] From another perspective, the first position may refer to a position that shields an insertion travel path formed by a part of the first trapping portion 510 and the second trapping portion 520 when the first trapping portion 510 or the second trapping portion 520 is inserted into the trapping portion accommodation space 360a.

[0303] Here, for the first trapping portion 510, a part of the structure that shields the insertion travel path may be an outer plate 522 (refer to Figure 31 ). For the second trapping portion 520, the part of the structure may be a rib 5161c protruding from the main body cover 516 (refer to Figure 23 ).

[0304] Due to contact with the first trapping portion 510 (specifically, the outer plate 522) or the second trapping portion 520 (specifically, the rib 5161c), the interference protrusion 3632 can move to a second position (Position2) to avoid interference with the cover 370.

[0305] On the other hand, the cover protrusion 371 may be formed to protrude from the cover 370.

[0306] When the cover 370 rotates to close the open side of the chamber main body 361, the cover protrusion 371 can be arranged at a position where it contacts the above-mentioned interference protrusion 3632 (refer to Figure 15 ). That is, the interference between the interference protrusion 3632 and the cover 370 means that the interference protrusion 3632 and the cover protrusion 371 contact each other.

[0307] The guide rail portion 363 may further include a protrusion guide 3633.

[0308] Next, referring to Figure 17 and Figure 18 , the protrusion guide 3633 can be combined with the interference protrusion 3632. The protrusion guide 3633 can guide the movement of the interference protrusion 3632.

[0309] More specifically, the protrusion guide 3633 has a space formed inside for accommodating the interference protrusion 3632, and a locking platform 3662 may be formed inside the space, and the locking platform 3662 engages with a hook 3632a formed at the end of the interference protrusion 3632.

[0310] In a state where the hook 3632a and the locking platform 3662 are in contact with each other, the interference protrusion 3632 can be arranged at the first position. As the interference protrusion 3632 moves from the first position to the second position, the contact between the hook 3632a and the locking platform 3662 can be released (refer to Figure 19 ).

[0311] The guide rail portion 363 may further include a restoring member 3634.

[0312] Referring to Figure 18 , the restoring member 3634 can be coupled to a space formed inside the interference protrusion 3632. The direction in which the interference protrusion 3632 is moved from the first position to the second position is defined as the first moving direction (md1), and the direction opposite to the first moving direction is defined as the second moving direction (md2). The restoring member 3634 can provide an elastic force in the second moving direction to the interference protrusion 3632, and the interference protrusion 3632 can be moved in the second moving direction by the restoring member 3634 until the hook 3632a and the locking table 3662 come into contact.

[0313] Referring to Figure 19 , the operation of the interference protrusion 3632 in the case where the trapping unit 500 is inserted into the trapping unit accommodation space 360a and in the case where it is not inserted into the trapping unit accommodation space 360a will be described.

[0314] Figure 19 is a diagram for explaining the movement of the interference protrusion 3632 in the embodiments of the present invention and the positional relationship with the cover 370 caused thereby.

[0315] Figure 19 The left drawing of shows the state where the cover protrusion 371 and the interference protrusion 3632 are in contact when the interference protrusion 3632 is in the first position. At this time, as the cover protrusion 371 comes into contact with the interference protrusion 3632, the direction in which the force is applied to the interference protrusion 3632 and the direction in which the interference protrusion 3632 is moved from the first position to the second position can form a prescribed angle.

[0316] The force does not have a component in the direction of moving the interference protrusion 3632 from the first position to the second position. Therefore, the force pressed by the cover protrusion 371 cannot cause the movement of the interference protrusion 3632, and the interference protrusion 3632 cannot further rotate the cover 370, so the chamber body 361 cannot be closed.

[0317] Figure 19 The right drawing of shows the case where the interference protrusion 3632 is in the second position, and the cover protrusion 371 is not in contact with the interference protrusion 3632. The cover 370 can be rotationally moved until the open side of the chamber body 361 is completely closed.

[0318] At this time, the first trapping unit 510 or the second trapping unit 520 causes the interference protrusion 3632 to move from the first position to the second position. When the first trapping unit 510 or the second trapping unit 520 is inserted into the trapping unit accommodation space 360a, a part 5162a of the configuration of the first trapping unit 510 or the second trapping unit 520 can push the interference protrusion 3632 to the second position.

[0319] An inclined portion 3632c that comes into contact with a part of the trapping portion 500 may be provided on the interference projection 3632.

[0320] Referring to Figure 15 , the chamber portion 360 may further include a filter mounting portion 365.

[0321] The filter mounting portion 365 may be disposed at the lower part of the chamber main body 361. The filter mounting portion 365 may refer to including a filter mounting space and a mounting wall. The filter mounting space is for the pre-filter module 470 that filters the air passing through the trapping portion 500 to be detachably coupled, and the mounting wall surrounds the filter mounting space.

[0322] At this time, the above-mentioned air outlet 3612 is formed at the lower end of the mounting wall. From another perspective, the air outlet 3612 is formed at the lower end of the filter mounting space.

[0323] When the pre-filter module 470 is in a state of being coupled to the filter mounting portion 365, the air flowing out of the trapping portion 500 toward the air outlet 3612 moves to the dust suction module 390 via the air outlet 3612 after passing through the pre-filter module 470.

[0324] When the pre-filter module 470 is not in a state of being coupled to the filter mounting portion 365, the air flowing out of the trapping portion 500 directly moves to the dust suction module 390 through the air outlet 3612.

[0325] Figure 20 This is a view showing the pre-filter module 470 in the embodiments of the present invention separated and unfolded in units.

[0326] Referring to Figure 20 , the pre-filter module 470 may include filter housings 471, 472 and filters 473, 474.

[0327] The filter housings 471, 472 may be composed of a housing upper part 471 and a housing lower part 472, and the housing upper part 471 and the housing lower part 472 may be hingedly coupled. If rotated about the hinge, the space inside the housing can be opened and closed.

[0328] An air inlet 4711 is formed in the housing upper part 471.

[0329] The air inlet 4711 can be formed on the top surface of the upper housing part 471 in a form corresponding to the form of the discharge flow path 518 of the first trapping part 510 described later. The air flowing out of the discharge flow path 518 of the first trapping part 510 can flow into the interior of the filter housings 471 and 472 through the air inlet 4711. The air flowing out of the dust bag 521 of the second trapping part 520 can flow into the interior of the filter housings 471 and 472 through the air inlet 4711.

[0330] An air outlet 4721 is formed in the lower housing part 472.

[0331] The air outlet 4721 can be formed by a plurality of holes penetrating the bottom surface of the lower housing part 472. The air outlet 4721 can be arranged to be distributed over the entire area of the bottom surface of the lower housing part 472 so that air can pass through the filter evenly.

[0332] At least one filter 473, 474 can be accommodated in the internal space formed by the upper housing part 471 and the lower housing part 472. The filters 473, 474 can include a first filter 473 made of a sponge material. The filters 473, 474 can include a second filter 474 made of a non-woven fabric material.

[0333] A pressing projection 4712 can be formed to protrude on one side of the filter housings 471, 472.

[0334] The pressing projection 4712 is configured to press a filter sensing projection 366 described later when the pre-filter module 470 is installed in the filter mounting part 365. The pressing projection 4712 can be formed in the form of a rib protruding from one surface of the upper housing part 471 or the lower housing part 472. (Refer to Figure 22 )

[0335] Refer to Figure 15 , the chamber part 360 can further include a filter sensing projection 366.

[0336] The filter sensing projection 366 can be arranged at the lower part of the chamber body 361. More specifically, the filter sensing projection 366 can be arranged adjacent to the mounting wall of the filter mounting part 365.

[0337] One side of the filter sensing projection 366 can be kept in a state of protruding toward the trapping part accommodation space 360a in a state where the pre-filter module 470 is not coupled to the filter mounting part 365.

[0338] For this purpose, although not shown, a pressing device that applies a force in the direction of protruding the said one side can be coupled to the filter sensing projection 366. For example, the pressing device can be an elastic body such as a spring.

[0339] In this way, when the filter sensing protrusion 366 protrudes toward the trapping part accommodation space 360a on one side, the rear side of the first trapping part 510 interferes with the filter sensing protrusion 366, so that the first trapping part 510 cannot be completely inserted into the trapping part accommodation space 360a.

[0340] On the contrary, the second trapping part 520 remains separated from the lower end of the chamber body 361 even when the dust bag 521 is fully inflated. Therefore, the insertion of the second trapping part 520 is not hindered by the filter sensing protrusion 366.

[0341] With this configuration, when the pre-filter module 470 is not installed in the filter installation part 365, the user cannot use the first trapping part 510. If the user forgets this after separating the pre-filter module 470 and inserts the first trapping part 510 into the chamber body 361, it will be stuck by the filter sensing protrusion 366 and cannot be fully inserted. The user can insert the first trapping part 510 into the chamber body 361 again after installing the pre-filter module 470 in the filter installation part 365.

[0342] On the other hand, when the pre-filter module 470 is coupled to the filter installation part 365, one side of the filter sensing protrusion 366 can be pressed by the pre-filter module 470. At this time, the filter sensing protrusion 366 can move in a direction to avoid interference with the first trapping part 510.

[0343] Figure 21 It is an enlarged view showing Figure 15 part "B", and it is a diagram for explaining the movement of the filter sensing protrusion 366 caused by whether the pre-filter module 470 is installed or not. Figure 22 It is Figure 21 a D-D' cross-sectional view.

[0344] Referring to Figure 21 and Figure 22 the filter sensing protrusion 366 may include: a protrusion main body 3661; and a locking table 3662, which is formed to protrude on the outer surface of the protrusion main body 3661. At this time, a space for arranging the above-mentioned pressing device (not shown) may be formed inside the protrusion main body 3661.

[0345] Referring to Figure 21 the left-side drawing of Figure 22 and the left-side drawing of

[0346] Figure 21The right-side attached drawing shows the state where the pre-filter module 470 is installed in the filter installation part 365. Referring together to Figure 22 the right-side attached drawing, the locking table 3662 of the filter sensing protrusion 366 is pressed by the pressing protrusion 4712.

[0347] At this time, as shown in Figure 22 the embodiment of, the pressing protrusion 4712 can protrude from one surface of the upper part 471 of the housing. As the pre-filter module 470 is installed in the filter installation part 365, the pressing protrusion 4712 can contact the locking table 3662, occupying the trapping part accommodation space 360a, so that one side of the filter sensing protrusion 366 in the protruding state can be pressed downward.

[0348] Thus, the first trapping part 510 can be completely inserted into the chamber main body 361 without interference.

[0349] On the other hand, the necessity of the above-mentioned filter sensing protrusion 366 is related to the difference in the dust separation device between the first trapping part 510 and the second trapping part 520.

[0350] As the dust separation device of the first trapping part 510, it can include a mesh net 5121 and a cyclone 513.

[0351] As the dust separation device of the second trapping part 520, it can include a dust bag 521 made of a breathable material.

[0352] In the case of the second trapping part 520, dust larger than the specified size in structure cannot pass through the dust bag 521. Since the dust bag 521 itself can perform the function of the pre-filter, the installation of the pre-filter module 470 is a user's choice and not necessary.

[0353] However, in the case of the first trapping part 510, fine dust can be roughly separated by the dust collection function of the cyclone 513, but it cannot completely filter fine dust in structure like the dust bag 521 of the first trapping part 510.

[0354] Therefore, in order to prevent fine dust from flowing into the dust collection motor 391, the pre-filter module 470 must be arranged on the path where the air passing through the first trapping part 510 flows into the dust collection motor 391.

[0355] The embodiment of the present invention has the effect of reminding the user to pay attention to the fact that the pre-filter module 470 is not installed when using the first trapping part 510.

[0356] In addition, the embodiment of the present invention has the effect that the second trapping part 520 can be used regardless of whether the pre-filter module 470 is installed, and the filter purchase cost can be reduced according to the user's choice.

[0357] Reference Figure 13 The chamber part 360 may further include a sterilization module mounting part 364.

[0358] The sterilization module mounting part 364 may be disposed at the upper part of the chamber main body 361. The sterilization module mounting part 364 may be spaced apart from the air inlet 3611. The sterilization module mounting part 364 may include: a sterilization module mounting space formed by bending a part of the top surface of the chamber main body 361 upward; and a mounting wall surrounding the mounting space.

[0359] A sterilization module 450 may be installed in the sterilization module mounting part 364 to irradiate ultraviolet light toward the trapping part accommodation space 360a.

[0360] The sterilization module 450 is configured to sterilize the dust trapped in the trapping part 500. The sterilization module 450 may include: a light source that emits sterilizing light; and a protection panel disposed below the light source to protect the light source.

[0361] In an implementable embodiment, the light source and the protection panel may be installed in the sterilization module mounting part 364 in a form of being accommodated in an additionally provided cover body. Or, in an implementable embodiment, the light source and the protection panel may be installed in the sterilization module mounting space in a form of being directly accommodated in the sterilization module mounting space.

[0362] In this way, as long as the light source of the sterilization module 450 is configured to emit sterilizing light toward the trapping part accommodation space 360a, the configuration form of the combination of the sterilization module 450 and the sterilization module mounting part 364 is not limited to a certain embodiment.

[0363] Here, the light source may include at least one light emitting diode (LED) that can emit sterilizing light having a sterilizing power capable of sterilizing. The sterilizing light emitted by the light source may have different wavelengths depending on the type of the light emitting diode.

[0364] As an example, the light source may be a light emitting diode that emits ultraviolet light in the range of the UV-C wavelength. Ultraviolet light is divided into UV-A (315 nm to 400 nm), UV-B (280 nm to 315 nm), and UV-C (200 nm to 280 nm) according to the wavelength. Among them, the ultraviolet light in the UV-C region destroys the DNA double helix of microorganisms, thereby being able to inhibit the reproduction of microorganisms.

[0365] Or, as another example, the light source may be a light emitting diode that emits visible light having a wavelength of 405 nm. The blue light having a wavelength of 405 nm has a wavelength in the boundary region between visible light and ultraviolet light, and its sterilizing power has been confirmed.

[0366] To prevent damage to the light source, the protection panel may be disposed at a predetermined distance from the light source. At this time, the protection panel may be made of a material that maximizes the transmittance of the light source. As an example, the protection panel may be made of quartz. It is known that quartz does not impede the transmission of ultraviolet light in the UV-C region.

[0367] An advantage of an embodiment of the present invention is that, since the sterilization module 450 and the sterilization module mounting portion 364 are provided, even when the dust sucked from the dust bin 220 of the vacuum cleaner 200 is stored in the trapping unit 500 for a long time, the vacuum cleaner base station 300 can be hygienically managed.

[0368] In addition, an advantage of an embodiment of the present invention is that, since the sterilization module mounting portion 364 is disposed in the chamber portion 360, the sterilization function can be used regardless of the type of trapping unit 500 selected by the user.

[0369] Hereinafter, the detailed structure of the first trapping unit 510 will be described.

[0370] Figure 23 is a perspective view of the first trapping unit 510 in an embodiment of the present invention, Figure 24 is a view showing the related components of the first trapping unit 510 in an embodiment of the present invention separated and unfolded, Figure 25 shows the dust separation process of the cyclone 513 in an embodiment of the present invention, Figure 26 is Figure 23 an X-X' cross-sectional view of.

[0371] Referring to Figures 23 to 26 , the first trapping unit 510 may include a trapping unit main body 511, a trapping unit inner wall 512, and a cyclone 513.

[0372] The trapping unit main body 511 forms the appearance of the dust accommodation space. In an implementable embodiment, the trapping unit main body 511 may have a substantially hexahedral shape. In another implementable embodiment, the trapping unit main body 511 may have a substantially cylindrical shape.

[0373] The first trapping unit 510 may further include a main body cover 516 to cover the open upper side of the first trapping unit 510 main body.

[0374] The shape of the main body cover 516 may be formed corresponding to the shape of the guide rail portion 363.

[0375] More specifically, the main body cover 516 may include a first cover portion 5161 and a second cover portion 5162.

[0376] The top surface of the first cover portion 5161 can be formed to have an inclined surface with a rear-downward inclination. Thus, it can be formed such that the height from the rear to the upper end of the first trapping portion 510 is low, and the height from the front to the upper end is high.

[0377] On the other hand, as described above, the trapping portion accommodation space 360a formed by the chamber main body 361 can be formed such that the cross-sectional area of the front end portion is larger than the cross-sectional area of the rear end portion.

[0378] That is, the height of the rear of the first trapping portion 510 where insertion into the trapping portion accommodation space 360a starts is low, and the height of the front end portion of the trapping portion accommodation space 360a which is the entrance for inserting the first trapping portion 510 is high. Therefore, the first trapping portion 510 can be easily inserted into the trapping portion accommodation space 360a.

[0379] The second cover portion 5162 can be connected to the left and right sides of the first cover portion 5161. The second cover portion 5162 can be formed in a shape that extends horizontally from the lower end of the side surface of the first cover portion 5161. That is, the top surface of the first cover portion 5161 and the top surface of the second cover portion 5162 can form a step where the top surface of the first cover portion 5161 is at a higher position.

[0380] In a state where the first trapping portion 510 is inserted into the chamber main body 361, the side surface of the first cover portion 5161 is disposed opposite to the side surface of the guide rail main body 3631. More specifically, the left and right side surfaces of the first cover portion 5161 are disposed opposite to the side surfaces of the left and right side guide rail main bodies 3631. From another perspective, the first cover portion 5161 is disposed between the left and right side guide rail main bodies 3631. (Refer to Figure 29 )

[0381] In a state where the first trapping portion 510 is inserted into the chamber main body 361, the top surface of the second cover portion 5162 is disposed opposite to the bottom surface of the guide rail main body 3631.

[0382] A transmissive panel 5161b can be disposed on the top surface of the first cover portion 5161.

[0383] The transmissive panel 5161b is disposed at a position corresponding to the position where the sterilization module 450 is disposed when the first trapping portion 510 is inserted into the chamber main body 361. That is, when the first trapping portion 510 is inserted into the chamber main body 361, the sterilization module 450 and the transmissive panel 5161b are disposed opposite to each other.

[0384] The transmissive panel 5161b can have a material that enables the sterilization light emitted from the sterilization module 450 to be transmitted into the interior of the trapping portion main body 511. As an example, the transmissive panel 5161b can be made of PMMA (Poly methyl methacrylate) material.

[0385] On the top surface of the first cover portion 5161, a dust inlet 5161a may be formed for air and dust to flow into from the first flow path 381. As an example, the dust inlet 5161a may have a circular shape. The first flow path 381 is connected to the upper side of the dust inlet 5161a. Thus, the air sucked by the suction force of the dust collection motor 391 can flow into the collection part main body 511. The dust inlet 5161a may be disposed above the first dust accommodation space S1 described later.

[0386] Based on the state where the first collection part 510 is inserted into the chamber main body 361, the dust inlet 5161a and the air inlet 3611 of the chamber main body 361 may face each other.

[0387] At this time, since the dust inlet 5161a is formed on the top surface of the first cover portion 5161 having a rear-downward inclination, the cross section of the dust inlet 5161a also has a rear-downward inclination. It was previously described that the cross section of the air inlet 3611 also has a rear-downward inclination. Since the air inlet 3611 and the dust inlet 5161a have inclinations in the same direction, they can be sealed without gaps.

[0388] On the inner top surface of the first cover portion 5161, an inflow cover 5163 for opening and closing the dust inlet 5161a may be joined. The inflow cover 5163 is a component for closing or opening the dust inlet 5161a, has a shape corresponding to the shape of the dust inlet 5161a, and can be joined to one side of the dust inlet 5161a.

[0389] The inflow cover 5163 can be opened by the suction force of the dust collection motor 391. That is, the inflow cover 5163 can be opened toward the inner space of the collection part main body 511 (specifically, the first dust accommodation space S1).

[0390] The inflow cover 5163 remains in a state of closing the dust inlet 5161a when the dust collection motor 391 is not driven, and can open the dust inlet 5161a when the dust collection motor 391 starts to drive.

[0391] For this purpose, a device for applying a restoring force in the direction of closing the dust inlet 5161a may be provided on the inflow cover 5163. The restoring force applying device may be an elastic member such as a spring.

[0392] With this configuration, in a state where no suction force is applied, the inflow cover 5163 always remains in a state of closing the dust inlet 5161a, preventing the odor, contamination, bacteria, etc. that may be generated inside the first collection part 510 from spreading to the first flow path 381.

[0393] On the outer side surface of the first cover portion 5161, a rib 5161c may be formed to protrude.

[0394] Here, the outer side surface may refer to the surface connecting the top surface of the first cover portion 5161 and the top surface of the second cover portion 5162.

[0395] A rib 5161c may be formed in front of the outer side surface of the first cover portion 5161. The rib may protrude in a direction parallel to the top surface of the second cover portion 5162. As the first trapping portion 510 is inserted into the chamber main body 361, the rib 5161c may be inserted into the sliding space of the guide rail portion 363 (specifically, the guide rail main body 3631).

[0396] As the first trapping portion 510 is inserted into the chamber main body 361, the rib 5161c may push the interference protrusion 3632 disposed at the first position to the second position. (Refer to Figure 19 )

[0397] The first trapping portion 510 may further include a lower cover 517 that covers the open lower side of the main body of the first trapping portion 510.

[0398] A trapping portion hinge 519 may be disposed on one side of the edge of the lower cover 517. If the lower cover 517 rotates about the trapping portion hinge 519, the inside of the trapping portion main body 511 may be opened. Thus, the user can discharge the dust collected in the trapping portion main body 511 to the outside and remove it.

[0399] A handle 5111b may be disposed on the front surface (or the front side) of the trapping portion main body 511. The handle 5111b is configured to be held by the user so as to be able to pull out the first trapping portion 510 to the outside of the chamber main body 361. The user can hold the handle 5111b and pull the first trapping portion 510 forward, so that the first trapping portion 510 can be easily pulled out from the chamber main body 361.

[0400] Finger grooves 5111a may be provided in the trapping portion main body 511 to enable the user to easily hold the handle 5111b. The finger grooves 5111a are formed as grooves that can insert the user's fingers. The finger grooves 5111a are formed in a shape in which the trapping portion main body 511 is recessed deeper into the internal space of the first trapping portion 510.

[0401] With this configuration, the handle 5111b does not protrude excessively to the outside of the trapping portion main body 511. That is, with this configuration, it is possible to contribute to the miniaturization of the vacuum cleaner base station 300.

[0402] The trapping portion inner wall 512 may be disposed inside the dust accommodation space of the trapping portion main body 511. The trapping portion inner wall 512 may divide the dust accommodation space of the trapping portion main body 511 into two separate spaces. The trapping portion inner wall 512 may be disposed in a direction perpendicular to the ground.

[0403] A mesh net 5121 may be provided on the inner wall 512 of the trapping section. For example, the mesh net 5121 may form a part of the inner wall 512 of the trapping section. That is, when air flows from one side to the other side of the divided dust accommodation space, it can pass through the mesh net 5121.

[0404] On the other hand, the accommodation space inside the first trapping section 510 is divided by the inner wall 512 of the trapping section into a first dust accommodation space S1 and a second dust accommodation space S2.

[0405] A compression rotating section 515 may be arranged in the first dust accommodation space S1. A cyclone 513 may be arranged in the second dust accommodation space S2. The air inhaled from the outside through the first flow path 381 first flows into the first dust accommodation space S1 and then flows through the mesh net 5121 into the second dust accommodation space S2.

[0406] Thus, larger dust can be filtered in the mesh net 5121. The filtered larger dust accumulates and is stored on the lower side of the first dust accommodation space S1.

[0407] There may be a plurality of cyclones 513. For example, there may be at least two cyclone bodies in a conical shape or a cylindrical shape.

[0408] Refer to Figure 25 , each cyclone body includes an inflow body 5131 for the air passing through the mesh net 5121 to flow in. Each cyclone body further includes an outflow body 5132 connected to the discharge flow path 518.

[0409] The discharge flow path 518 is a flow path connected to the side of the dust collecting motor 391 and, as described above, is a flow path forming a part of the second flow path 382.

[0410] Due to the suction force applied to the discharge flow path 518, air is inhaled from the outflow body 5132, and a cyclone flow is generated in the inflow body 5131. Due to this cyclone flow, minute dust can be filtered from the air passing through the mesh net 5121.

[0411] The first trapping section 510 may include a compression rotating section 515.

[0412] The compression rotating section 515 is a component provided for compressing the dust collected in the first trapping section 510.

[0413] Refer to Figure 24 and Figure 26 , the compression rotating section 515 is arranged inside the dust accommodation space of the trapping section main body 511. More specifically, the compression rotating section 515 is arranged inside the first accommodation space S1 of the trapping section main body 511.

[0414] The compression rotating part 515 is movably arranged inside the trapping part main body 511. The compression rotating part 515 can move in the direction of compressing the dust collected inside the first dust accommodation space S1. In an embodiment of the present invention, the compression rotating part 515 can be rotatably arranged in the first dust accommodation space S1.

[0415] The compression rotating part 515 can rotate around an axis arranged along the length direction inside the trapping part main body 511 (the first dust accommodation space S1). More specifically, the compression rotating part 515 can include a rotating shaft member 5151, a fixing plate 5152, and a rotating plate 5153.

[0416] The rotating shaft member 5151 can be arranged along the up and down direction inside the trapping part main body 511, that is, in the first dust accommodation space S1. The rotating shaft member 5151 can rotate by receiving the power of the aforementioned compression motor 3622. The central axis of the rotating shaft member 5151 can be coaxial with the central axis of the first dust accommodation space S1.

[0417] The lower end part of the rotating shaft member 5151 can be connected to and supported by the floor surface of the first dust accommodation space S1. The upper end part of the rotating shaft member 5151 can be separated from the dust inlet 5161a by a predetermined distance so as not to obstruct the opening of the inflow cover 5163. (Refer to Figure 30 )

[0418] The fixing plate 5152 can be fixedly arranged on one side inside the first trapping part 510. More specifically, the fixing plate 5152 is arranged along the up and down direction in the first dust accommodation space S1 and can be fixedly joined to one side of the inner peripheral surface of the trapping part main body 511 forming the first dust accommodation space S1. The fixing plate 5152 can have a quadrilateral flat plate shape. The fixing plate 5152 can be arranged on the side opposite to the mesh net 5121.

[0419] The fixing plate 5152 completely shields or shields a predetermined part of the first dust accommodation space S1, so that it can compress the dust pushed by the rotation of the rotating plate 5153 together with the rotating plate 5153.

[0420] The rotating plate 5153 is connected to the outer peripheral surface of the rotating shaft member 5151 and can rotate together with the rotating shaft member 5151. More specifically, the rotating plate 5153 can rotate between the inner peripheral surface of the trapping part main body 511 forming the first dust accommodation space S1 and the outer peripheral surface of the rotating shaft member 5151.

[0421] The shape of the rotating plate 5153 is basically a quadrilateral flat plate shape, and it can be deformed into a shape that avoids interference with other components arranged in the first dust accommodation space S1. For example, a cut portion may be formed at the upper end of the rotating plate 5153 to prevent interference with the rotation radius of the inflow cover 5163 when the inflow cover 5163 opens the dust inlet 5161a. (Refer to Figure 30 )

[0422] The rotating plate 5153 can rotate in the forward and reverse directions. Taking the state of observing the first dust accommodation space S1 from above (i.e., the state of observing the first trapping portion 510 from above) as a reference, the clockwise rotation can be defined as the forward rotation, and the counterclockwise rotation can be defined as the reverse rotation.

[0423] If the rotating plate 5153 rotates in the forward direction, one surface of the rotating plate 5153 and one surface of the fixed plate 5152 can meet to compress the dust. Similarly, if the rotating plate 5153 rotates in the reverse direction, the other surface of the rotating plate 5153 and the other surface of the fixed plate 5152 can meet to compress the dust. That is, a part of the compressed dust exists near one surface of the fixed plate 5152, and the rest exists near the other surface of the fixed plate 5152.

[0424] The compression rotating portion 515 may further include a cleaning member 5154.

[0425] Refer to Figure 24 and Figure 26 , the cleaning member 5154 is coupled to the end of the rotating plate 5153 on the opposite side of the rotating shaft member 5151. That is, one end of the rotating plate 5153 is coupled to the rotating shaft member 5151, and the other end is coupled to the cleaning member 5154.

[0426] The cleaning member 5154 can rotate together with the rotating plate 5153 in a state of contacting the mesh net 5121. More specifically, one side edge of the cleaning member 5154 can be arranged to contact one surface of the mesh net 5121.

[0427] Thus, when the cleaning member 5154 rotates together with the rotating plate 5153, it can rotate while scraping the mesh net 5121, and can remove foreign substances attached to the mesh net 5121. For example, the cleaning member 5154 can be a brush made of rubber material.

[0428] On the other hand, as described above, the first trapping portion 510 may include a transmission gear 514.

[0429] The transmission gear 514 can be coupled to the lower cover 517 of the first trapping unit 510. When the first trapping unit 510 is inserted into the trapping unit accommodation space 360a, the transmission gear 514 and the driving gear 3621 can be engaged with each other, and the rotational power of the compression motor 3622 can be transmitted to the compression rotating unit 515 through the driving gear 3621 and the transmission gear 514.

[0430] With Figure 24 reference to Figure 27 and Figure 28 , the transmission gear 514 and the driving gear 3621 will be described in detail.

[0431] Figure 27 is an enlarged view of the driving gear 3621 and the transmission gear 514 in an embodiment of the present invention, Figure 28 is a perspective view of the driving gear 3621 in an embodiment of the present invention as viewed from below.

[0432] The transmission gear 514 can be connected to the rotating shaft member 5151 of the compression rotating unit 515. Gear teeth 5142 that mesh with the driving gear 3621 are disposed on the lower outer periphery of the transmission gear 514. A gear shaft 5141 that is coaxially connected to the rotating shaft member 5151 is disposed at the upper center of the transmission gear 514.

[0433] The gear shaft 5141 can be inserted into the interior of the accommodation space of the trapping unit main body 511 through a hole formed in the lower cover 517. The gear shaft 5141 can be configured to be insertable into the hollow formed in the rotating shaft member 5151. That is, the dimension of the outer peripheral surface diameter of the gear shaft 5141 can be formed to be smaller than the dimension of the outer peripheral surface diameter of the rotating shaft member 5151.

[0434] A mechanical structure that meshes with each other can be formed between the gear shaft 5141 and the rotating shaft member 5151 so that they can rotate at the same angular velocity. For example, the mechanical structure can be a protrusion and groove structure.

[0435] The driving gear 3621 can include a gear main body 3621a, a shaft connecting portion 3621b, and gear teeth 3621c.

[0436] The gear main body 3621a can form the appearance of the driving gear 3621. Gear teeth 3621c that mesh with the gear teeth 5142 of the transmission gear 514 are formed on the upper portion of the gear main body 3621a. A pattern 3621d in which protrusions and grooves are alternately continuous can be formed on the lower outer periphery of the gear main body 3621a.

[0437] The diameter dimension of the upper side of the gear main body 3621a where the gear teeth 3621c are disposed and the diameter dimension of the lower side of the gear main body 3621a where the pattern 3621d is formed can be different from each other.

[0438] An axial connection portion 3621b connected to the motor shaft of the compression motor 3622 is formed at the center of the gear body 3621a. The axial connection portion 3621b may be formed in a cylindrical shape inside the gear body 3621a. The axial connection portion 3621b may be formed with a hole corresponding to the motor shaft to insert the motor shaft.

[0439] Thus, when the compression motor 3622 rotates, the drive gear 3621 rotates together.

[0440] A plurality of ribs 3621e may be radially arranged on the outer peripheral surface of the axial connection portion 3621b to support the shape of the axial connection portion 3621b.

[0441] The pattern 3621d formed on the drive gear 3621 may be formed such that the widths of the adjacent protrusions and the widths of the grooves are different from each other. The protrusions and grooves formed in the pattern 3621d may be defined as phases distinguished according to the magnitudes of the formed widths.

[0442] At this time, the order of the phase arrangements of the pattern 3621d may be formed differently in the first direction d1 on the outer periphery of the gear body 3621a and in the second direction d2 opposite to the first direction d1.

[0443] The pattern 3621d may be composed of four phases as a group. Here, the first phase and the third phase may be formed in a protrusion shape, and the second phase and the fourth phase may be formed in a groove shape. That is, the protrusions and grooves may be alternately formed.

[0444] Here, the widths of the first to fourth phases may be formed to be all different, and each phase may be distinguished by the magnitude of the width. Figure 28 Taking the illustrated embodiment as an example, a protrusion with a width of pt_d1 (mm) may be defined as the first phase, a groove with a width of pt_d2 (mm) may be defined as the second phase, a protrusion with a width of pt_d3 (mm) may be defined as the third phase, and a groove with a width of pt_d4 (mm) may be defined as the fourth phase.

[0445] When observing while moving the gear body 3621a of the drive gear 3621 in the first rotation direction rd1, the arrangement order of each phase may repeat in the order of 1-2-3-4. Therefore, when observing the gear body 3621a of the drive gear 3621 while moving in the second rotation direction rd2 opposite to the first rotation direction rd1, each phase repeats in the order of 4-3-2-1.

[0446] Thus, by the configuration of the directional pattern 3621d formed on the drive gear 3621, the control unit 700 described later can sense whether the drive gear 3621 is rotating in the current first rotation direction rd1 or the second rotation direction rd2.

[0447] Figure 29 FIG. is a perspective view showing a state in which the first trapping unit 510 in an embodiment of the present invention is inserted into the chamber body 361, Figure 30 FIG. is a diagram showing a flow path of air related to dust collection in a state where the first trapping unit 510 in an embodiment of the present invention is inserted into the chamber body 361.

[0448] Air flowing into the first dust accommodation space S1 inside the trapping unit main body 511 via the first flow path 381 separates large dust while passing through the mesh net 5121, and the air from which the large dust has been separated flows into the second dust accommodation space S2.

[0449] Then, the air flowing into the second dust accommodation space S2 separates fine dust while passing through the cyclone 513, and the air from which the fine dust has been separated flows into the discharge flow path 518 provided in the trapping unit main body 511.

[0450] The air flowing out of the discharge flow path 518 flows to the dust collection motor 391 via the pre-filter module 470.

[0451] Hereinafter, the detailed structure of the second trapping unit 520 will be described.

[0452] Figure 31 FIG. is a diagram showing the related components of the second trapping unit 520 in an embodiment of the present invention separated and developed, Figure 32 FIG. is a cross-sectional view of the second trapping unit 520 in an embodiment of the present invention as viewed from the side.

[0453] Refer to Figure 31 and Figure 32 , the second trapping unit 520 may include a dust bag 521, an outer plate 522, and an inner plate 523.

[0454] The dust bag 521 is configured to accommodate dust sucked from the vacuum cleaner 200 and store it inside.

[0455] When the suction force is generated by the dust collection motor 391, the volume of the dust bag 521 can increase to accommodate dust inside. For this purpose, the dust bag 521 may be formed of a breathable material. More specifically, the dust bag 521 may be formed of a material that allows air to pass through but does not allow foreign substances such as dust to pass through. As an example, the dust bag 521 may be made of a non-woven fabric material and may have a hexahedron shape based on the increased volume.

[0456] A dust inlet 5212 is formed in the dust bag 521. The dust inlet 5212 is formed by penetrating the dust bag 521 on the upper side thereof, and is a passage for guiding the air and dust flowing in from the air inlet 3611 of the chamber body 361 into the interior of the dust bag 521.

[0457] The dust bag 521 may include a light transmission hole 5211. The light transmission hole 5211 may be formed by penetrating the dust bag 521. The light transmission hole 5211 may be formed at a position opposite to one surface of a transmission panel 524 described later. That is, the light transmission hole 5211 may be disposed in front of the dust inlet 5212. In a state where the second trapping portion 520 is completely inserted into the trapping portion accommodation space 360a, the sterilization module 450 may be disposed above the light transmission hole 5211. Thus, the sterilization light can be irradiated into the interior of the dust bag 521 through the transmission panel 524.

[0458] The outer plate 522 may be coupled to the outer upper side of the dust bag 521.

[0459] The outer plate 522 may include a plate body 5221 having a quadrilateral flat plate shape.

[0460] A part of the left and right side ends of the plate body 5221 may be inserted into the sliding space of the guide rail body 3631. From another perspective, the left and right side ends of the plate body 5221 are inserted and coupled to the guide rail body 3631, and one surface of the plate body 5221 may be supported by the inner bottom surface of the guide rail body 3631. With this configuration, the plate body 5221 can be inserted into the guide rail body 3631 in a sliding manner.

[0461] A dust inlet 5222 is formed in the plate body 5221. The dust inlet 5222 is a passage for guiding the air and dust flowing in from the air inlet 3611 of the chamber body 361 into the interior of the dust bag 521.

[0462] The outer plate 522 may include a handle 5223.

[0463] The handle 5223 may be coupled to the front end of the plate body 5221. The handle 5223 may be integrally formed with the plate body 5221. The handle 5223 may be formed by being vertically connected to the plate body 5221.

[0464] The user can push the outer plate 522 into the guide rail body 3631 by holding the handle 5223. The user can pull the outer plate 522 out of the guide rail body 3631 by holding the handle 5223.

[0465] The outer plate 522 may include a connecting member 5224.

[0466] The connecting member 5224 can be disposed behind the dust flow inlet 5222. The connecting member 5224 can be formed in a shape that protrudes downward from the bottom surface of the outer plate 522 by a predetermined length. The connecting member 5224 can be coupled to the internal plate 523 described later through the dust bag 521.

[0467] The outer plate 522 can include a support member 5225.

[0468] The support member 5225 can be disposed in front of the outer plate 522. The support member 5225 can be formed in a shape that protrudes downward from the bottom surface of the outer plate 522 by a predetermined length.

[0469] The support members 5225 are respectively formed in a rib shape on the left and right sides of the outer plate 522. With the outer plate 522 inserted into the guide rail main body 3631 as a reference, the lower end thereof can contact the lower inner surface of the guide rail main body 3631.

[0470] As the second trapping portion 520 is inserted into the trapping portion accommodation space 360a, the front thereof is lifted by the support member 5225. That is, in a state where the second trapping portion 520 is completely inserted into the trapping portion accommodation space 360a, the second trapping portion 520 can be inclined in a manner having a rearward-downward inclination. (Refer to Figure 34 )

[0471] With this configuration, the outer plate 522 can be supported in a state of rising toward the air inlet 3611 of the chamber main body 361.

[0472] As described above, in the embodiment of the present invention, the open cross section of the air inlet 3611 has a rearward-downward inclination. At this time, the second trapping portion 520 can also be inserted into the guide rail portion 363 in an inclined state with a rearward-downward inclination. Since the air inlet 3611 and the dust flow inlet 5222 have the same-direction inclination, they can be sealed without a gap therebetween.

[0473] The outer plate 522 can include a light transmission hole 5226.

[0474] The light transmission hole 5226 can be formed through the plate main body 5221. The light transmission hole 5226 can be formed at a position opposite to one surface of the transmission panel 524 described later. That is, the light transmission hole 5226 can be disposed in front of the dust flow inlet 5222.

[0475] In a state where the second trapping portion 520 is completely inserted into the trapping portion accommodation space 360a, the sterilization module 450 can be disposed above the light transmission hole 5226. Thus, the sterilization light can be irradiated onto the inside of the dust bag 521 through the transmission panel 524.

[0476] The inner plate 523 can be incorporated inside the upper side of the dust bag 521.

[0477] The inner plate 523 can include a plate body 5231 in the form of a quadrilateral flat plate.

[0478] A dust inlet 5232 is formed in the plate body 5231. The dust inlet 5232 is a passage for guiding the air and dust flowing in from the air inlet 3611 of the chamber body 361 into the inside of the dust bag 521.

[0479] The inner plate 523 can include side walls 5233.

[0480] The side walls 5233 are components that restrict and guide the flow direction of the air flowing into the inside of the dust bag 521. The side walls 5233 can be arranged adjacent to the dust inlet 5232. The side walls 5233 can be formed to protrude downward from the inner surface of the plate body 5231. That is, the side walls 5233 can be arranged to extend into the inner space of the dust bag 521.

[0481] The side walls 5233 can be symmetrically arranged on the left and right sides of the dust inlet 5232. Therefore, the side walls 5233 can block the air flowing in through the dust inlet 5232 from flowing to the left or right.

[0482] On the other hand, in a state where the inflow cover 525 described later is open, the rearward flow of air can also be blocked.

[0483] As a result, the air flowing in through the dust inlet 5232 can flow downward in the forward direction.

[0484] With this configuration, the inflowing dust can be effectively exposed to the sterilizing light irradiated in front of the dust inlet 5232.

[0485] The inner plate 523 can include a connection member insertion groove 5234.

[0486] The connection member insertion groove 5234 can be arranged behind the dust inlet 5232. The connection member insertion groove 5234 can be formed in a shape that penetrates the plate body 5231. The connection member 5224 of the outer plate 522 can be inserted into the connection member insertion groove 5234.

[0487] The inner plate 523 can include an inflow pipe 5235.

[0488] The inflow pipe 5235 can be joined to the bottom surface of the plate body 5231. The inflow pipe 5235 can be arranged in a shape that surrounds the dust inlet 5232. The inflow pipe 5235 can be integrally formed with the plate body 5231. The open cross-section of the inflow pipe 5235 can have a rearward-downward inclination.

[0489] The lower end of the inflow pipe 5235 can be closed by an inflow cover 525 described later. Thus, the dust inlet 5232 can also be closed.

[0490] The inner plate 523 can include an inflow cover fixing member 5236.

[0491] The inflow cover fixing member 5236 can be disposed behind the dust inlet 5232. The inflow cover fixing member 5236 can be coupled to the bottom surface of the plate body 5231 in a form surrounding the connection member insertion groove 5234. The inflow cover fixing member 5236 can be integrally formed with the plate body 5231.

[0492] An inflow cover insertion groove 5236a can be formed in the inflow cover fixing member 5236. At least a part of the inflow cover 525 can be inserted and fixed in the inflow cover insertion groove 5236a. The inflow cover insertion groove 5236a has an inclined surface sloping downward to the rear and can extend in the left - right direction. Therefore, the inflow cover 525 can be inserted downward from the front upper part toward the rear.

[0493] A transmissive panel 524 can be coupled to the inner plate 523.

[0494] When the second trapping unit 520 is inserted into the chamber body 361, the transmissive panel 524 is disposed at a position corresponding to the position where the sterilization module 450 is disposed. That is, when the second trapping unit 520 is inserted into the chamber body 361, the sterilization module 450 and the transmissive panel 524 are disposed opposite to each other.

[0495] The transmissive panel 524 can have a material through which the sterilization light emitted from the sterilization module 450 can be transmitted to the inside of the trapping unit main body 511. As an example, the transmissive panel 524 can be formed of a PMMA (Poly methyl methacrylate) material.

[0496] An inflow cover 525 for opening and closing the dust inlet 5232 can be coupled to the inside of the inner plate 523. The inflow cover 525 can be disposed at the end of the inflow pipe 5235.

[0497] The inflow cover 525 can be formed of an elastic material. For example, the inflow cover 525 can be formed of a rubber material.

[0498] The inflow cover 525 can be opened on one side of the inflow pipe 5235 by the suction force of the dust collection motor 391. That is, the inflow cover 525 can be opened toward the inner space of the dust bag 521.

[0499] One side of the inflow cover 525 can be inserted and coupled to the inflow cover insertion groove 5236a.

[0500] The inflow cover insertion groove 5236a has a large rear - downward inclination, while the open cross - section of the inflow pipe 5235 has a smaller rear - downward inclination than the inflow cover insertion groove 5236a. When the inflow cover 525 is inserted into the inflow cover insertion groove 5236a, its shape deforms into a shape bent at one part.

[0501] At this time, the inflow cover 525 applies a restoring force in the direction of wanting to unfold again with the bent part as a reference.

[0502] With this structure, in the state where the inflow cover 525 is inserted into the inflow cover insertion groove 5236a, the inflow cover 525 can closely adhere to the inflow pipe 5235. That is, the inflow cover 525 will not sink due to its own weight when the dust collection motor 391 is not driven.

[0503] The inflow cover 525 keeps the dust inlet 5232 closed when the dust collection motor 391 is not driven, and can open the dust inlet 5232 when the dust collection motor 391 starts to drive.

[0504] When the dust collection motor 391 operates, the inflow cover 525 deforms towards the inner space of the dust bag 521 while opening the inflow pipe 5235, and when the dust collection motor 391 stops, it closes the inflow pipe 5235 by elastic restoration.

[0505] Therefore, it has the effect of preventing dust from flying outwards, insects from escaping, or odors from spreading when the second trapping part 520 is separated from the vacuum cleaner base station.

[0506] In addition, in the state where the second trapping part 520 is combined with the vacuum cleaner base station, since the inflow pipe 5235 is closed when the dust collection motor 391 is not driven, it has the effect of preventing dust or odors from flowing back through the first flow path 381.

[0507] Figure 33 It is a perspective view showing the state where the second trapping part 520 in the embodiment of the present invention is inserted into the chamber main body 361. Figure 34 It is a diagram showing the flow path of air related to dust collection in the state where the second trapping part 520 in the embodiment of the present invention is inserted into the chamber main body 361.

[0508] If an air flow is formed by the suction force of the dust collection motor 391, the air containing foreign matters flowing from the inside of the dust bin 220 of the vacuum cleaner 200 moves to the dust bag 521 through the first flow path 381, and only the foreign matters are left in the dust bag 521 and the air flows out of the dust bag 521.

[0509] At this time, for the dust flowing in through the first flow path 381, the left - right direction flow is blocked by the side wall 5233, and the rear - side direction flow is blocked by the inflow cover 525, as Figure 34As shown by the arrow direction, the sterilizing light irradiated toward the sterilization module 450 flows downward in the front direction.

[0510] In addition, the air flowing out of the dust bag 521 flows through the pre-filter module 470 to the dust collection motor 391.

[0511] On the other hand, when the dust collection motor 391 is driven to form an air flow in the second collection part 520, the gear through-hole 3613a is directly exposed without being blocked, so a suction force is also applied to the gear through-hole 3613a. (Refer to Figure 33 the direction of the dotted arrow shown)

[0512] In this way, when a suction force is directly applied to the compression motor 3622 through the gear through-hole 3613a, the compression motor 3622 may malfunction.

[0513] Figure 35 is a cross-sectional view showing an enlarged view of the sealing member 3623 that seals the gear through-hole 3613a in the embodiment of the present invention.

[0514] In the embodiment of the present invention, the compression driving part 362 may further include a sealing member 3623 disposed between the driving gear 3621 and the chamber body 361.

[0515] The sealing member 3623 may be disposed along the entire outer side of the gear body 3621a of the driving gear 3621. The sealing member 3623 may be disposed between the outer side surface of the gear body 3621a of the driving gear 3621 and the lower outer side surface of the chamber body 361.

[0516] In this way, the sealing member 3623 seals between the gear through-hole 3613a and the compression motor 3622, thereby blocking the air flow between the compression motor 3622 and the collection part accommodation space 360a.

[0517] The sealing member 3623 may include a first sealing part in contact with the chamber body 361 and a second sealing part in contact with the gear body 3621a. The first sealing part and the second sealing part may be configured in a form in which they are connected to each other at one end and separated at the other end.

[0518] With this configuration, as the suction force is applied by the dust collection motor 391, the sealing part is compressed in the direction in which the other side of the first sealing part and the other side of the second sealing part approach each other. Therefore, by driving the dust collection motor 391, the sealing force is further strengthened, preventing a suction force from being directly applied to the compression motor 3622.

[0519] Figure 36 is a block diagram of the vacuum cleaner base station 300 according to an embodiment of the present invention.

[0520] Refer toFigure 36 The vacuum cleaner base station 300 may further include a control unit 700 that controls each component of the vacuum cleaner base station 300. The control unit 700 may be mounted on a printed circuit board.

[0521] The control unit 700 may include all types of devices capable of processing data, such as a processor. Here, the "processor" may refer to a data processing device of hardware built into a circuit having a physical structure in order to execute functions expressed by codes or commands included in a program, for example. As an example of a data processing device built into hardware as described above, it may include a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), and other processing devices, but the scope of the present invention is not limited thereto.

[0522] If the coupling sensor 325 senses the coupling of the vacuum cleaner 200, the coupling sensor 325 may transmit a signal indicating that the vacuum cleaner 200 is coupled to the coupling portion 320 to the control unit 700. At this time, the control unit 700 may receive the signal of the coupling sensor 325 and determine that the vacuum cleaner 200 is coupled to the coupling portion 320.

[0523] In addition, if power is supplied from the charging terminal 328 to the battery 240 of the vacuum cleaner 200, the control unit 700 may determine that the vacuum cleaner 200 is coupled to the coupling portion 320.

[0524] If it is determined that the vacuum cleaner 200 is coupled to the coupling portion 320, the control unit 700 may control the fixing unit motor 780 to rotate forward to fix the vacuum cleaner 200 to the coupling portion 320.

[0525] The vacuum cleaner base station 300 may further include a fixing sensing unit 770. If the fixing member 331 or the fixing unit link 335 moves to a predetermined fixing position, the fixing sensing unit 770 transmits a signal indicating that the vacuum cleaner 200 is fixed to the coupling portion 320 to the control unit 700.

[0526] The control unit 700 may receive a signal indicating that the vacuum cleaner 200 is fixed from the fixing sensing unit 770 and determine that the vacuum cleaner 200 is fixed to the coupling portion 320. If it is determined that the vacuum cleaner 200 is fixed, the control unit 700 may control to stop the driving of the fixing unit motor 780.

[0527] On the other hand, if the emptying of the dust bin 220 is completed, the control unit 700 can control the fixing unit motor 780 to rotate in the reverse direction to release the fixing of the vacuum cleaner 200 and the coupling unit 320.

[0528] The control unit 700 can control the door motor 342 to rotate in the forward direction to open the door 341 of the vacuum cleaner base 300.

[0529] The vacuum cleaner base 300 may further include a door opening / closing sensing unit 760. If the door 341 or the door arm 343 reaches a predetermined open position, the door opening / closing sensing unit 760 transmits a signal indicating that the door 341 is open to the control unit 700.

[0530] The control unit 700 can receive a signal from the door opening / closing sensing unit 760 to determine that the door 341 is in an open state. If it is determined that the door 341 is open, the control unit 700 can control to stop the driving of the door motor 342.

[0531] On the other hand, if the emptying of the dust bin 220 is completed, the control unit 700 can control the door motor 342 to rotate in the reverse direction to close the door 341.

[0532] The control unit 700 can drive the control cover opening motor 352 to open the discharge cover 222 of the vacuum cleaner 220.

[0533] The vacuum cleaner base 300 may further include a cover opening sensing unit 720. If the push protrusion 351 reaches a predetermined open position, the cover opening sensing unit 720 can transmit a signal indicating that the discharge cover 222 is open to the control unit 700.

[0534] The control unit 700 can receive a signal from the cover opening sensing unit 720 to determine that the discharge cover 222 is in an open state. If it is determined that the discharge cover 222 is open, the control unit 700 can control to stop the driving of the cover opening motor 352.

[0535] The control unit 700 can control the sterilization module 450. As an example, the control unit 700 can turn on the light source of the sterilization module 450 after the dust is trapped in the trapping unit 500 or at a predetermined time interval to sterilize viruses, microorganisms, etc. present inside the trapping unit 500.

[0536] The control unit 700 can control the driving of the dust collection motor 391. The control unit 700 can control the dust collection motor 391 to drive for a predetermined time to suck the dust inside the dust bin 220 into the trapping unit 500.

[0537] The control unit 700 can control the compression motor 3622. The control unit 700 can control the compression motor 3622 to drive more than a specified number of times and / or for more than a specified time to compress the dust collected inside the collection unit 500 (specifically, the first collection unit 510).

[0538] If it is determined that the vacuum cleaner 200 is in a state of being coupled to the coupling part 320, the control unit 700 can control the compression motor 3622 to drive. After the dust collection is completed and the dust collection motor 391 stops driving, the control unit 700 can control the compression motor 3622 to drive.

[0539] The control unit 700 can control the display unit 730. The control unit 700 can display various information related to the driving of the vacuum cleaner base station 300 on the display unit 730.

[0540] For example, the information may include the status of emptying the dust bin 220 of the vacuum cleaner 200, the charging level of the vacuum cleaner 200, an explanation of the components currently in operation, the degree of dust compression, etc.

[0541] The control unit 700 can display a notification on the display unit 730 in a plurality of preset steps according to the amount of dust collected in the collection unit 500. For example, the control unit 700 can divide the notification regarding the dust compression state into a plurality of steps and display it on the display unit 730 according to the amount of dust collected.

[0542] Furthermore, the control unit 700 can display on the display unit 730 that the dust collection motor 391 cannot be driven to remind the user to remove the dust collected in the collection unit 500 at an appropriate time.

[0543] The vacuum cleaner base station 300 may further include a memory 740. An application program for driving the vacuum cleaner base station 300 and various related data can be stored in the memory 740.

[0544] The preset values related to the driving of the vacuum cleaner base station 300 described in this specification can be stored in the memory 740.

[0545] The memory 740 may include magnetic storage media or flash storage media, but the scope of the present invention is not limited thereto. Such a memory 740 may include built-in memory and / or external memory, may also include volatile memories such as DRAM, SRAM, SDRAM, etc., may also include non-volatile memories such as OTPROM (one time programmable ROM), PROM (programmable read only memory), EPROM (erasable programmable read only memory), EEPROM (electrically erasable programmable read only memory), maskROM (mask read only memory), flashROM (flash read only memory), NAND flash, NOR flash, etc., may also include flash drives such as SSD (solid state drive), CF (compactflash) card, SD card, Micro-SD card, Mini-SD card, Xd card, memory stick, or storage devices such as HDD.

[0546] The memory 740 may be included in the control unit 700 or may be provided as an independent component.

[0547] The vacuum cleaner base station 300 may further include an input unit 750. The input unit 750 generates key input data input by the user to control the operation of the vacuum cleaner base station 300. For this purpose, the input unit 750 may be composed of a key pad, a dome switch, a touch pad (static pressure / electrostatic), etc. In particular, when the touch pad and the display unit 730 form a layer structure with each other, it may be referred to as a touch screen.

[0548] The input unit 750 and / or the display unit 730 may be disposed on the upper surface 313 of the cover 310.

[0549] On the other hand, the vacuum cleaner base station 300 may distinguish the type of the trapping unit 500 coupled to the chamber unit 360 based on the operation mode of the compression driving unit 362.

[0550] The control unit 700 may control the compression driving unit 362. More specifically, the control unit 700 may control the rotational driving of the compression motor 3622.

[0551] The control unit 700 may rotate the compression motor 3622 to distinguish the type of the trapping unit 500.

[0552] Hereinafter, a method for distinguishing or determining the type of the trapping unit 500 will be described in detail.

[0553] If the dust bin 220 of the vacuum cleaner 200 is combined with the cover body 310, the control unit 700 can drive 3622. That is, if the dust bin 220 is combined with the cover body 310, the compression motor 3622 can be automatically driven.

[0554] In another embodiment, if the user presses the action button of the vacuum cleaner base station 300, the control unit 700 can drive the compression motor 3622. That is, if the dust bin 220 is combined with the cover body 310, the compression motor 3622 can be manually driven. At this time, the action button can be arranged on the display unit 730.

[0555] In still another embodiment, if the trapping unit 500 is combined with the chamber unit 360, the control unit 700 can drive the compression motor 3622. In this embodiment, different from the foregoing embodiments, the compression motor 3622 can be driven regardless of whether the dust bin 220 is combined with the cover body 310.

[0556] The driving of the compression motor 3622 performed to determine the type of the trapping unit 500 needs to be carried out before the dust collection motor 391 for collecting dust is driven. At this time, regardless of the type of the trapping unit 500 combined with the chamber unit 360, the driving of the compression motor 3622 needs to be performed. That is, whether the chamber main body 361 is combined with the first trapping unit 510 or the second trapping unit 520, the control unit 700 drives the compression motor 3622.

[0557] The control unit 700 can cause the compression driving unit 362 to drive for a preset first time t1.

[0558] The control unit 700 can determine the type of the trapping unit 500 currently combined with the chamber unit 360 by whether the rotation direction of the compression driving unit 362 is switched within the first time t1.

[0559] At this time, the first time t1 can be set to a value larger than the time required for the rotating plate 5153 mechanically combined with the compression driving unit 362 to rotate 360 degrees inside the first trapping unit 510.

[0560] In a state where the first trapping unit 510 is inserted into the chamber main body 361, the rotation direction of the compression driving unit 362 will necessarily be switched within the first time t1.

[0561] The state where the first trapping unit 510 is inserted into the chamber main body 361 means a state where the driving gear 3621 combined with the compression motor 3622 is gear-connected to the transmission gear 514 of the first trapping unit 510.

[0562] When the compression motor 3622 rotates, the rotational power transmitted through the drive gear 3621 and the transmission gear 514 causes the rotating plate 5153 to rotate. When the rotating plate 5153 rotates only in one direction, it is blocked by the fixed plate 5152 or the dust accumulated inside the first trapping unit 510, so it cannot rotate more than 360 degrees in one direction.

[0563] That is, before the rotating plate 5153 rotates 360 degrees, the compression drive unit 362 must necessarily change the rotation direction to the opposite direction.

[0564] The control unit 700 can determine that the first trapping unit 510 is in a state combined with the chamber unit 360 by sensing the rotation direction change performed by the compression drive unit 362 within the first time t1.

[0565] On the other hand, the first time t1 is not necessarily the time required for the rotating plate 5153 to rotate 360 degrees. The first time t1 can be set to other appropriate values calculated considering the initial position and rotation speed of the rotating plate 5153, the position of the fixed plate 5152, etc.

[0566] On the other hand, since the drive gear 3621 and the compression motor 3622 constituting the compression drive unit 362 are longitudinally connected and rotate in the same direction, in this specification, the rotation direction of the compression drive unit 362 has the same meaning as the rotation direction of the drive gear 3621 or the rotation direction of the compression motor 3622.

[0567] The sensing of the rotation direction change of the compression drive unit 362 can be achieved by sensing the arrangement order of the pattern 3621d formed on the drive gear 3621. For this purpose, a compression state sensing unit 790 can also be provided in the compression drive unit 362 adjacent to the drive gear 3621. The compression state sensing unit 790 can be a photo interrupter.

[0568] The compression state sensing unit 790 can sense the change of the pattern 3621d of the drive gear 3621 to generate an on / off signal. The on signal corresponds to a high signal, and the off signal corresponds to a low signal.

[0569] The control unit 700 can receive the signal transmitted by the compression state sensing unit 790 to determine the phase of the current pattern 3621d of the drive gear 3621.

[0570] If the phase of the pattern 3621d sensed by the compression state sensing unit 790 has a configuration order of 1-2-3-4, the compression driving unit 362 is rotating in the first direction. If the phase of the pattern 3621d sensed by the light blocker has a configuration order of 4-3-2-1, the compression driving unit 362 is rotating in the second direction. (Refer to Figure 28 )

[0571] If a first time t1 has elapsed from the rotation start time point, the compression driving unit 362 may stop.

[0572] On the other hand, differently, when the second trapping unit 520 is inserted into the chamber body 361, the compression driving unit 362 does not change the rotation direction within the first time t1. This is because the second trapping unit 520 is of the dust bag type, so there is no member that can be connected to the driving gear 3621. (Refer to Figure 33 )

[0573] That is, the compression driving unit 362 continuously rotates in one direction within the first time t1. Thus, the control unit 700 can determine that the second trapping unit 520 is in a state of being combined with the chamber unit 360.

[0574] If a first time t1 has elapsed from the rotation start time point, the compression driving unit 362 may stop.

[0575] Hereinafter, the driving of the vacuum cleaner base station 300 after determining the type of the trapping unit 500 will be described.

[0576] In the embodiment of the present invention, the vacuum cleaner base station 300 can be driven differently according to the type of the trapping unit 500 combined with the chamber unit 360.

[0577] Hereinafter, the driving of the vacuum cleaner base station 300 when the first trapping unit 510 is combined with the chamber unit 360 will be described.

[0578] If the dust bin 220 is combined with the cover 310 of the vacuum cleaner base station 300, the fixing unit 330 can fix and seal the dust bin 220. The cover opening unit 350 can open the discharge cover 215 of the dust bin 220. The door unit 340 can open the door 341 of the vacuum cleaner base station 300.

[0579] If the inside of the dust bin 220 and the inside of the flow path unit 380 are in communication, the dust collecting motor 391 is driven, so that the dust inside the dust bin 220 can flow into the inside of the first trapping unit 510 through the flow path unit 380. That is, the dust inside the dust bin 220 can be removed.

[0580] If the dust collection motor 391 stops after driving for a specified time, the process of compressing the dust collected in the first trapping unit 510 can be performed. This process is only carried out when the trapping unit 500 is the first trapping unit 510 of the "bucket" type.

[0581] More specifically, the compression motor 3622 can be rotationally driven so that the rotational power is transmitted to the rotary plate 5153 via the drive gear 3621 and the transmission gear 514. The rotary plate 5153 rotates in a manner close to the fixed plate 5152 fixedly arranged on one side of the first trapping unit 510, thereby enabling the dust accumulated between the fixed plates 5152 to be pressurized and compressed.

[0582] After the compression drive unit 362 stops driving and the dust compression is completed, the door unit 340 can close the door 341 of the vacuum cleaner base station 300. At this time, the door unit 340 can push the discharge cover 215 of the dust bin 220 while closing the door 341, so that the dust bin 220 and the discharge cover 215 can be re - combined. The fixing unit 330 that previously fixed and sealed the dust bin 220 can be driven to release the fixed state.

[0583] Next, the driving of the vacuum cleaner base station 300 when the second trapping unit 520 is combined with the chamber unit 360 will be described.

[0584] If the dust bin 220 is combined with the cover 310 of the vacuum cleaner base station 300, the fixing unit 330 can fix and seal the dust bin 220. The cover opening unit 350 can open the discharge cover 215 of the dust bin 220. The door unit 340 can open the door 341 of the vacuum cleaner base station 300.

[0585] If the interior of the dust bin 220 and the interior of the flow path unit 380 are in communication, the dust collection motor 391 is driven, so that the dust inside the dust bin 220 can flow into the interior of the second trapping unit 520 through the flow path unit 380. That is, the dust inside the dust bin 220 can be removed.

[0586] Since the second trapping unit 520 is of the dust bag type, when the second trapping unit 520 is combined with the chamber unit 360, after the dust collection motor 391 is driven, the compression drive unit 362 will not be driven.

[0587] That is, when the second collection unit 520 is coupled to the chamber unit 360, after the dust collection motor 391 stops driving, the compression driving unit 362 is not driven, and the door unit 340 can immediately close the door 341 of the vacuum cleaner base 300. At this time, the door unit 340 can push the discharge cover 215 of the dust bin 220 while closing the door 341, so that the dust bin 220 and the discharge cover 215 can be re-coupled. The fixing unit 330 that previously fixed and sealed the dust bin 220 can be driven to release the fixed state.

[0588] As described above, the embodiments of the present invention can distinguish the collection unit currently coupled to the vacuum cleaner base, so the vacuum cleaner base can be efficiently driven according to the form of the collection unit.

[0589] In addition, the collection unit can be distinguished by using the compression driving unit provided for compressing dust, without the need to additionally provide a sensor.

[0590] The preferred embodiments of the present invention have been shown and described above. However, the present invention is not limited to the above specific embodiments. Obviously, those skilled in the art of the present invention can perform various modified implementations without departing from the gist of the present invention to be protected in the claims. Such modified implementations should not be understood separately from the technical idea and prospect of the present invention.
