Description

Technical Field

[0001] The present invention relates to a vacuum cleaner base station, and more particularly, to a vacuum cleaner base station capable of separating dust contained in the air and collecting the dust in a dust bag, and capable of emptying only the dust bag. Background Art

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

[0003] Such vacuum cleaners can be divided into manual vacuum cleaners, which are vacuum cleaners that are directly moved by the user to clean, and automatic vacuum cleaners, which are vacuum cleaners that move and clean autonomously. Manual vacuum cleaners can be divided into canister-type vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick-type vacuum cleaners, etc., according to the form of the vacuum cleaner.

[0004] In the past, canister vacuum cleaners were widely used as household vacuum cleaners. However, in recent years, there has been a trend to increasingly use handheld vacuum cleaners and stick vacuum cleaners that have improved ease of use by integrating a dust container and a vacuum cleaner body.

[0005] In a canister vacuum cleaner, a main body and a suction port are connected by a hose or a pipe, and a brush can be attached to the suction port for use according to circumstances.

[0006] A handheld vacuum cleaner is a vacuum cleaner that maximizes portability, and although it is lightweight, it is short so that the area where you can sit down to clean it may be limited. Therefore, it is used to clean local areas such as desks, sofas, or cars.

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

[0008] In recent years, cleaning robots that clean autonomously without user operation have been used. The cleaning robots autonomously drive in an area to be cleaned while sucking in foreign matter such as dust from the ground, thereby automatically cleaning the area to be cleaned.

[0009] However, the existing handheld vacuum cleaners, stick vacuum cleaners and sweeping robots have a small dust bucket for storing collected dust, so it is inconvenient for the user to empty the dust bucket every time.

[0010] In addition, since dust is scattered when the dust barrel is emptied, there is a problem of adversely affecting the health of the user.

[0011] In addition, there is a problem that, when the remaining dust in the dust bucket is not removed, the suction power of the vacuum cleaner is reduced.

[0012] In addition, there is a problem that when the remaining dust in the dust barrel is not removed, the residue causes a bad smell.

[0013] As a prior art patent document, Korean Laid-Open Patent Publication KR10-2161708B1 discloses a base station including a dust bag.

[0014] In the prior art patent document, a base station is included which is combined with a dust bucket of a vacuum cleaner, and a dust bag is arranged on the base station. In this case, the dust bag can be combined with the inside of the cover of the vacuum cleaner along a sliding groove, and the outer surface of the dust bag is made of a material that can filter air when it passes through.

[0015] However, in the case of the above-mentioned permeable or semi-permeable dust bag, there is a problem that dust inside the dust bag may leak out of the dust bag, and bad smell may also leak out of the dust bag.

[0016] In addition, as a conventional patent document, Korean Patent Publication KR10-2021-0019940A discloses a vacuum cleaner base station that captures dust collected in a dust bucket of a vacuum cleaner.

[0017] The vacuum cleaner base station of the existing patent document includes: a vacuum cleaner that sucks in and stores dust in the air; and a vacuum cleaner base station that is combined with the dust bucket to remove the dust stored in the dust bucket; the vacuum cleaner base station includes a dust collecting motor that sucks in foreign matter and internal air in the dust bucket combined with the vacuum cleaner base station, and includes a plastic bag type dust collecting part.

[0018] However, in the vacuum cleaner base station, when the dust collecting motor is operated, the plastic bag is pulled toward the dust collecting motor side and may be crushed.

[0019] Therefore, in the vacuum cleaner base station, when the dust collecting motor is operated, it is difficult to collect dust in the plastic bag as the internal space of the plastic bag becomes narrower.

[0020] In addition, in the vacuum cleaner base station, since the dust is collected in the plastic bag without being separated from the air, there is a problem that part of the dust flows into the dust collecting motor side.

[0021] On the other hand, the above-mentioned vacuum cleaner base station needs to have a box capable of replacing the consumable plastic bag.

[0022] In this case, since the plastic bag replacement box is detachably coupled to the cover body, there is a problem that dust contained in the air may be scattered through the space where the box is coupled.

[0023] Furthermore, in the case where the box is not accurately mounted on the cover of the base station, a large amount of dust may be scattered during the dust collection process, thereby causing failure of components inside the base station.

[0024] Therefore, it is necessary to have a structure that prevents the cassette from being incorrectly installed and can sense whether the cassette is accurately installed. Summary of the invention

[0025] Problem to be solved

[0026] The present invention is proposed to improve the problems existing in the conventional vacuum cleaner base station as described above, and an object of the present invention is to provide a vacuum cleaner base station capable of maintaining the shape of a dust bag during dust collection.

[0027] Another object of the present invention is to provide a vacuum cleaner base station capable of separating dust from air and collecting the dust in a dust bag while the air containing dust flows toward a dust collecting motor.

[0028] In addition, the present invention also aims to provide a vacuum cleaner base station that does not require the user to directly bind a dust bag.

[0029] In addition, the present invention also aims to provide a vacuum cleaner base station in which a user can empty the dust bucket by removing only the dust bag.

[0030] In addition, an object of the present invention is to provide a vacuum cleaner base station capable of supplying a new dust bag when the dust bag is consumed.

[0031] Another object of the present invention is to provide a vacuum cleaner base station capable of preventing dust from scattering in a box that can supply a dust bag.

[0032] In addition, an object of the present invention is to provide a vacuum cleaner base station that can prevent the box from being incorrectly installed.

[0033] In addition, an object of the present invention is to provide a vacuum cleaner base station that can sense whether the box is accurately installed.

[0078] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0079] The present invention can be varied and can have various embodiments, so specific embodiments are shown in the drawings and are specifically described in the detailed description. This is not intended to limit the present invention to specific implementations, but should be interpreted as covering all changes, equivalents and even substitutes included in the concept and technical scope of the present invention.

[0081] Unless otherwise defined, all terms used herein, including technical or scientific terms, may have the meanings commonly understood by those skilled in the art to which the present invention belongs. Terms such as those defined in commonly used dictionaries may be interpreted as having meanings consistent with the meanings in the context of the relevant technology, and may not be interpreted as ideal or overly formal meanings unless otherwise clearly defined in the present invention.

[0082] Figure 1 A diagram is shown for explaining a vacuum cleaner system according to an embodiment of the present invention.

[0083] Reference Figure 1 , a vacuum cleaner system 1 according to an embodiment of the present specification may include a vacuum cleaner 200 and a vacuum cleaner base station 100 .

[0084] The vacuum cleaner system 1 may include a vacuum cleaner base station 100. A vacuum cleaner 200 may be combined with the vacuum cleaner base station 100. The vacuum cleaner 200 may be combined with the side of the vacuum cleaner base station 100. The vacuum cleaner base station 100 may remove dust from a dust barrel 220 of the vacuum cleaner 200.

[0085] Figure 2 A schematic diagram showing the structure of a vacuum cleaner according to an embodiment of the present invention is shown. Figure 3 Shown from different angles Figure 2 The vacuum cleaner picture, Figure 4A diagram showing the lower side of a dust bucket of a vacuum cleaner in a vacuum cleaner system for explaining an embodiment of the present invention is shown.

[0086] First, refer to Figures 2 to 4 The structure of the vacuum cleaner 200 will be described.

[0087] The vacuum cleaner 200 may be a vacuum cleaner manually operated by a user. For example, the vacuum cleaner 200 may be a handheld vacuum cleaner or a stick vacuum cleaner.

[0088] The vacuum cleaner 200 may be placed on the vacuum cleaner base station 100. The vacuum cleaner 200 may be supported by the vacuum cleaner base station 100. The vacuum cleaner 200 may be combined with the vacuum cleaner base station 100.

[0089] On the other hand, in one embodiment of the present invention, the direction of the vacuum cleaner 200 can be defined based on the bottom surface (lower side) of the dust bin 220 and the battery cover 230 placed on the ground.

[0090] At this time, the front may refer to the direction in which the suction unit 212 is configured with the suction motor 214 as a reference, and the rear may refer to the direction in which the handle 216 is configured with the suction motor 214 as a reference. Furthermore, the direction configured on the right side as a reference when observing the suction unit 212 from the suction motor 214 may be referred to as the right side, and the direction configured on the left side may be referred to as the left side. In addition, in one embodiment of the present invention, the upper side and the lower side may be defined along a direction perpendicular to the ground with the bottom surface (lower side) of the dust bin 220 and the battery cover 230 placed on the ground as a reference.

[0091] 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 .

[0092] 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 the filter (not shown) inside. The main body cover 211 may be configured in a shape similar to a cylinder.

[0093] 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 combined with the extension pipe 250. The suction part 212 may provide a flow path (hereinafter, referred to as "suction flow path") through which air containing dust can flow.

[0094] On the other hand, in the present embodiment, a virtual line penetrating the interior of the suction portion 212 formed in a cylindrical shape may be formed.

[0095] The dust separation part 213 may be communicated with the suction part 212. The dust separation part 213 may separate the dust sucked into the inside through the suction part 212. The space inside the dust separation part 213 may be communicated with the space inside the dust barrel 220.

[0096] For example, the dust separation unit 213 may have at least one cyclone unit capable of separating dust by cyclonic flow. Furthermore, the space inside the dust separation unit 213 may be connected to the suction flow path. Therefore, the air and dust sucked in by the suction unit 212 may flow in a spiral along the inner circumference of the dust separation unit 213. Therefore, a cyclonic flow may be generated in the internal space of the dust separation unit 213.

[0097] The dust separation unit 213 is communicated with the suction unit 212 and is constructed based on the principle of a dust collector using centrifugal force to separate dust sucked into the body 210 through the suction unit 212 .

[0098] The dust separator 213 may further include a secondary cyclone for separating dust from the air discharged from the cyclone again. In this case, the secondary cyclone may be located inside the cyclone to minimize the size of the dust separator. The secondary cyclone may include a plurality of cyclone bodies arranged in parallel. The air discharged from the cyclone may be diverted to and passed through the plurality of cyclone bodies.

[0099] At this time, the axis of the cyclone flow of the secondary cyclone can also extend in the up and down direction, and the axis of the cyclone flow of the cyclone can be coaxial with the axis of the cyclone flow of the secondary cyclone in the up and down direction, which can be collectively referred to as the axis of the cyclone flow of the dust separation part 213.

[0100] The suction motor 214 can generate suction force for sucking air. The suction motor 214 can be accommodated in the main housing 211. The suction motor 214 can generate suction force by rotating. As an example, the suction motor 214 can be formed similar to a cylindrical shape.

[0101] On the other hand, in the present embodiment, a virtual suction motor axis extending the rotation axis of the suction motor 214 may be formed.

[0102] The air discharge cover 215 may be disposed on one axial side of the main housing 211. A filter for filtering air may be accommodated in the air discharge cover 215. As an example, a high efficiency particulate air filter (High Efficiency Particulate Air Filter) may be accommodated in the air discharge cover 215.

[0103] The air discharge cover 215 may be formed with an air discharge port through which the air sucked by the suction force of the suction motor 214 is discharged.

[0104] A flow guide may be provided at the air discharge cover 215. The flow guide may guide the flow of the air discharged through the air discharge port.

[0105] The handle 216 can be held by the user. The handle 216 can be arranged behind the suction motor 214. As an example, the handle 216 can be formed similar to a cylindrical shape. Alternatively, the handle 216 can be formed in a curved cylindrical shape. The handle 216 can be arranged to form a specified angle with the main cover 211 or the suction motor 214 or the dust separation unit 213.

[0106] The handle 216 may include: a holding portion 216a, which is formed in a columnar shape so that the user can hold it; a first extension portion 216b, which is connected to one end portion of the holding portion 216a in the length direction (axial direction) and extends toward the suction motor 214; and a second extension portion 216c, which is connected to the other end portion of the holding portion 216a in the length direction (axial direction) and extends toward the dust bin 220.

[0107] On the other hand, in the present embodiment, a virtual gripping portion penetration line extending along the longitudinal direction of the gripping portion 216 a (the axial direction of the column) and penetrating the gripping portion 216 a may be formed.

[0108] As an example, the grip portion penetration line may be an imaginary line formed inside the cylindrical handle 216, and may be an imaginary line parallel to at least a portion of the outer side surface (outer peripheral surface) of the grip portion 216a.

[0109] The top surface of the handle 216 may form a part of the appearance of the top surface of the cleaner 200. Thus, when the user holds the handle 216, a part of the cleaner 200 may be prevented from contacting the user's arm.

[0110] The first extension portion may extend from the grip portion 216a toward the main body cover 211 or the suction motor 214. At least a portion of the first extension portion may extend in the horizontal direction.

[0111] The second extension portion may extend from the grip portion 216a toward the dust container 220. At least a portion of the second extension portion may extend in a horizontal direction.

[0112] The operation unit 218 may be disposed on the handle 216. The operation unit 218 may be disposed on an inclined surface formed in an upper region of the handle 216. The user may input an operation or stop command of the cleaner 200 through the operation unit 218.

[0113] The cleaner 200 may include a dust container 220. The dust container 220 may be in communication with the dust separation unit 213. The dust container 220 may store the dust separated in the dust separation unit 213.

[0114] The dust bin 220 may include a dust bin body 221 , a discharge cover 222 , a dust bin compression rod 223 , and a compression member (not shown).

[0115] The dust container body 221 may provide a space for storing the dust separated by the dust separation unit 213. As an example, the dust container body 221 may be formed similarly to a cylindrical shape.

[0116] On the other hand, in this embodiment, an imaginary dust bin penetration line can be formed that penetrates the interior (internal space) of the dust bin body 221 and extends along the length direction of the dust bin body 221 (referring to the axial direction of the cylindrical dust bin body 221).

[0117] A portion of the lower side (bottom) of the dust barrel body 221 may be open. In addition, a bottom surface extension 221a may be formed on the lower side (bottom) of the dust barrel body 221. The bottom surface extension 221a may be formed to block a portion of the lower side of the dust barrel body 221.

[0118] The dust container 220 may include a discharge cover 222. The discharge cover 222 may be disposed on the lower side of the dust container 220.

[0119] The discharge cover 222 may be configured to open and close one end portion of the length direction of the dust bin body 221. Specifically, the discharge cover 222 may selectively open and close the lower portion of the dust bin 220 that is open downward.

[0120] The discharge cover 222 may include a cover body 222a and a hinge portion 222b. The cover body 222a may be formed to block a portion of the lower side of the dust bin body 221. The cover body 222a may be rotated downward with the hinge portion 222b as a reference. The hinge portion 222b may be configured to be adjacent to the battery cover 230. A torsion spring 222d may be provided at the hinge portion 222b. Thus, when the discharge cover 222 is separated from the dust bin body 221, the cover body 222a may be supported by the elastic force of the torsion spring 222d in a state where it is rotated from the dust bin body 221 with the hinge portion 222b as an axis by more than a specified angle.

[0121] The discharge cover 222 can be combined with the dust bin 220 by hooking. On the other hand, the discharge cover 222 can be separated from the dust bin 220 by the coupling rod 222c. The coupling rod 222c can be arranged in front of the dust bin. Specifically, the coupling rod 222c can be arranged on the outer side of the front side of the dust bin 220. When an external force is applied, the coupling rod 222c can elastically deform the hook extending from the cover body 222a to release the hook coupling between the cover body 222a and the dust bin body 221.

[0122] When the discharge cover 222 is closed, the lower side of the dust container 220 may be blocked (sealed) by the discharge cover 222 and the bottom surface extension 221 a.

[0123] The dust container 220 may include a dust container compression rod 223 (see Figure 8 ). The dust bin compression rod 223 may be disposed outside the dust bin 220 or the dust separation portion 213. The dust bin compression rod 223 may be configured to be able to move up and down outside the dust bin 220 or the dust separation portion 213. The dust bin compression rod 223 may be connected to a compression member (not shown). In the case where the dust bin compression rod 223 moves downward due to an external force, the compression member (not shown) may also move downward together. Thus, user convenience may be provided. The compression member (not shown) and the dust bin compression rod 223 may return to their original positions using an elastic member (not shown). Specifically, in the case where the external force applied to the dust bin compression rod 223 is removed, the elastic member may enable the dust bin compression rod 223 and the compression member (not shown) to move upward.

[0124] A compression member (not shown) may be disposed inside the dust bin body 221. The compression member may move in the internal space of the dust bin body 221. Specifically, the compression member may move up and down inside the dust bin body 221. Thus, the compression member may compress the dust inside the dust bin body 221 downward. In addition, when the discharge cover 222 is separated from the dust bin body 221 and the lower portion of the dust bin 220 is opened, the compression member may move from the upper portion to the lower portion of the dust bin 220, thereby removing foreign matter such as residual dust inside the dust bin 220. Therefore, dust will not remain inside the dust bin 220, thereby being able to improve the suction power of the vacuum cleaner. In addition, the stench caused by the residue can be eliminated by preventing dust from remaining inside the dust bin 220.

[0125] The vacuum cleaner 200 may include a battery cover 230. The battery cover 230 may contain a battery 240. The battery cover 230 may be disposed on the lower side of the handle 216. As an example, the battery cover 230 may be in the shape of a hexahedron with an open lower portion. The back of the battery cover 230 may be connected to the handle 216.

[0126] The battery cover 230 may include a receiving portion open downward, and the battery 240 may be loaded and unloaded through the receiving portion of the battery cover 230 .

[0127] The vacuum cleaner 200 may include a battery 240 .

[0128] 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 from the bottom of the battery cover 230 into the interior of the battery cover 230. With the above configuration, the portability of the vacuum cleaner 200 may be improved.

[0129] Alternatively, the battery 240 may be integrally disposed inside the battery cover 230. In this case, the bottom surface of the battery 240 is not exposed to the outside.

[0130] The battery 240 can supply power to the suction motor 214 of the cleaner 200. The battery 240 can be disposed at the lower portion of the handle 216. The battery 240 can be disposed at the rear of the dust container 220.

[0131] According to an embodiment, when the battery 240 is combined with the battery cover 230, the bottom surface of the battery 240 may be exposed to the outside. When the vacuum cleaner 200 is placed on the ground, the battery 240 may be placed on the ground, so the battery 240 may be directly separated from the battery cover 230. In addition, since the bottom surface of the battery 240 is exposed to the outside and directly contacts the air outside the battery 240, the cooling performance of the battery 240 can be improved.

[0132] On the other hand, when the battery 240 is integrally fixed to the battery cover 230 , the structure for attaching and detaching the battery 240 and the battery cover 230 can be reduced, so the overall size of the cleaner 200 can be reduced and the weight can be reduced.

[0133] The cleaner 200 may include an extension pipe 250. The extension pipe 250 may be in communication with the cleaning module 260. The extension pipe 250 may be in communication with the main body 210. The extension pipe 250 may be in communication with the suction part 212 of the main body 210. The extension pipe 250 may be formed in a long cylindrical shape.

[0134] The main body 210 may be connected to the extension tube 250. The main body 210 may be connected to the cleaning module 260 using the extension tube 250. The main body 210 may generate suction through the suction motor 214 and provide suction to the cleaning module 260 through the extension tube 250. External dust may flow into the main body 210 through the cleaning module 260 and the extension tube 250.

[0135] The cleaner 200 may include a cleaning module 260. The cleaning module 260 may be in communication with the extension tube 250. Thus, by the suction force generated in the main body 210 of the cleaner 200, the external air may flow into the main body 210 of the cleaner 200 via the cleaning module 260 and the extension tube 250.

[0136] The dust in the dust bucket 220 of the vacuum cleaner 200 can be captured by the dust collecting unit 170 of the vacuum cleaner base station 100 due to gravity and the suction force of the dust collecting motor 191. Thus, the dust in the dust bucket can be removed without the user's additional operation, thereby improving user convenience. In addition, the trouble of the user emptying the dust bucket every time can be eliminated. In addition, dust can be prevented from scattering when the dust bucket is emptied.

[0137] The vacuum cleaner 200 may be combined with the side of the cover body 110. Specifically, the main body 210 of the vacuum cleaner 200 may be placed on the combination part 120. More specifically, the dust bucket 220 and the battery cover body 230 of the vacuum cleaner 200 may be combined with the combination surface 121, the outer peripheral surface of the dust bucket main body 221 may be combined with the dust bucket guide surface 122, and the suction part 212 may be combined with the suction part guide surface 126 of the combination part 120. In this case, the central axis of the dust bucket 220 may be arranged in a direction parallel to the ground, and the extension tube 250 may be arranged in a direction perpendicular to the ground.

Figure 6 A diagram showing a fixing unit in a vacuum cleaner base station for explaining an embodiment of the present invention is shown. Figure 7 and Figure 8 A diagram for explaining the relationship between a vacuum cleaner and a door unit in a vacuum cleaner base station according to an embodiment of the present invention is shown. Fig. 9 A diagram for explaining the relationship between a vacuum cleaner and a lid opening unit in a vacuum cleaner base station according to an embodiment of the present invention is shown.

[0139] Below, refer to Figures 5 to 9 The vacuum cleaner base station 100 of the present invention will be described.

[0140] The vacuum cleaner base station 100 may be combined with a vacuum cleaner 200. Specifically, a main body of the vacuum cleaner 200 may be combined with a side of the vacuum cleaner base station 100. The vacuum cleaner base station 100 may remove dust from a dust barrel 220 of the vacuum cleaner 200.

[0141] The vacuum cleaner base station 100 may include a cover 110. The cover 110 may form the appearance of the vacuum cleaner base station 100. Specifically, the cover 110 may be formed in a column shape including at least one outer wall surface. As an example, the cover 110 may be formed in a shape similar to a quadrangular prism.

[0142] The cover body 110 may be formed with a space capable of accommodating a dust collecting portion 170 in which dust is stored and a dust suction module 190 , wherein the dust collecting portion 170 generates a flow force for collecting dust into the dust collecting portion 170 .

[0143] The cover body 110 may include a bottom surface 111 , an outer wall surface 112 , and an upper surface 113 .

[0144] The bottom surface 111 may support the lower side of the dust suction module 190 in the gravity direction. That is, the bottom surface 111 may support the lower side of the dust collecting motor 191 of the dust suction module 190.

[0145] At this time, the bottom surface 111 can be configured to face the ground. The bottom surface 111 can be configured not only parallel to the ground, but also inclined at a predetermined angle relative to the ground. By the above-mentioned structure, the dust collecting motor 191 can be stably supported, and the overall weight can be balanced even when the vacuum cleaner 200 is combined.

[0146] On the other hand, according to an embodiment, the bottom surface 111 may further include a ground support portion 311a that increases the contact area with the ground to prevent the vacuum cleaner base station 100 from falling and maintain balance. As an example, the ground support portion 311a may be in the form of a plate extending from the bottom surface 111, or may be formed by one or more frames protruding and extending from the bottom surface 111 toward the ground.

[0147] The outer wall surface 112 may refer to a surface formed along the gravity direction, or may refer to a surface connected to the bottom surface 111. For example, the outer wall surface 112 may refer to a surface vertically connected to the bottom surface 111. As a different embodiment, the outer wall surface 112 may also be configured to be inclined at a predetermined angle to the bottom surface 111.

[0148] The outer wall surface 112 may include at least one surface. As an example, the outer wall surface 112 may include a first outer wall surface 112a, a second outer wall surface 112b, a third outer wall surface 112c, and a fourth outer wall surface 112d.

[0149] At this time, in this embodiment, the first outer wall surface 112a can be configured on the front side of the vacuum cleaner base station 100. Here, the front side can refer to the side where the vacuum cleaner 200 is exposed when the vacuum cleaner 200 is combined with the vacuum cleaner base station 100. Thus, the first outer wall surface 112a can form the appearance of the front side of the vacuum cleaner base station 100.

[0150] On the other hand, in order to understand the present embodiment, the following defines a direction. In the present embodiment, the direction may be defined in a state where the cleaner 200 is placed on the cleaner base station 100 .

[0151] When the vacuum cleaner 200 is placed on the vacuum cleaner base station 100 , the direction in which the vacuum cleaner 200 is exposed to the outside of the vacuum cleaner base station 100 may be referred to as the front.

[0152] From a different perspective, when the vacuum cleaner 200 is placed on the vacuum cleaner base station 100, the direction in which the suction motor 214 of the vacuum cleaner 200 is arranged can be called the front. In addition, the direction opposite to the direction in which the suction motor 214 is arranged in the vacuum cleaner base station 100 can be called the rear.

[0153] In addition, based on the internal space of the housing 110, the surface facing the front direction may be referred to as the back side of the vacuum cleaner base station 100. Therefore, the back side may refer to the direction in which the second outer wall surface 112b is formed.

[0154] In addition, the left side of the front side when the front side is viewed from the internal space of the cover body 110 as a reference may be referred to as the left side, and the right side may be referred to as the right side. Thus, the left side may refer to the direction in which the third outer wall surface 112c is formed, and the right side may refer to the direction in which the fourth outer wall surface 112d is formed.

[0155] The first outer wall surface 112a may be formed not only in a flat surface but also in a curved surface as a whole, or may be formed so as to include a curved surface in part.

[0156] The first outer wall surface 112a may be provided with a coupling portion 120. With this configuration, the vacuum cleaner 200 may be coupled to the vacuum cleaner base station 100 and supported by the vacuum cleaner base station 100. The specific configuration of the coupling portion 120 will be described later.

[0157] On the other hand, a structure for placing various types of cleaning modules 260 used in the cleaner 200 may be added to the first outer wall surface 112a.

[0158] In this embodiment, the second outer wall surface 112b may be a surface facing the first outer wall surface 112a. That is, the second outer wall surface 112b may be disposed on the back side of the vacuum cleaner base station 100. The second outer wall surface 112b may form the appearance of the back side of the vacuum cleaner base station 100.

[0159] In this embodiment, the third outer wall surface 112c and the fourth outer wall surface 112d may refer to surfaces connecting the first outer wall surface 112a and the second outer wall surface 112b. In this case, the third outer wall surface 112c may be arranged on the left side of the vacuum cleaner base station 100, and the fourth outer wall surface 112d may be arranged on the right side of the vacuum cleaner base station 100. Alternatively, the third outer wall surface 112c may be arranged on the right side of the vacuum cleaner base station 100, and the fourth outer wall surface 112d may be arranged on the left side of the vacuum cleaner base station 100.

[0160] The third outer wall surface 112c or the fourth outer wall surface 112d may be formed not only in a planar shape but also in a curved shape as a whole, or may be formed so as to include a curved surface in part.

[0161] On the other hand, a structure for placing various forms of cleaning modules 260 used in the cleaner 200 may be added to the third outer wall surface 112c or the fourth outer wall surface 112d.

[0162] The upper surface 113 may form the upper appearance of the vacuum cleaner base station. That is, the upper surface 113 may refer to a surface that is disposed at the uppermost side in the gravity direction in the vacuum cleaner base station and is exposed to the outside.

[0163] For reference, in the present embodiment, the upper side and the lower side may respectively refer to the upper side and the lower side along the gravity direction (the direction perpendicular to the ground) when the vacuum cleaner base station 100 is set on the ground.

[0164] At this time, the upper surface 113 may be arranged not only parallel to the ground but also inclined at a predetermined angle with respect to the ground.

[0165] A display unit may be disposed on the upper surface 113. For example, the display unit may display the status of the vacuum cleaner base station 100, the status of the vacuum cleaner 200, and other information such as the cleaning progress status and a map of the cleaning area.

[0166] On the other hand, according to an embodiment, the upper surface 113 may be configured to be detachable from the outer wall surface 112. At this time, when the upper surface 113 is detached, the battery detached from the vacuum cleaner 200 may be accommodated in the inner space surrounded by the outer wall surface 112, and a terminal (not shown) capable of charging the detached battery may be provided.

[0167] On the other hand, a bag accommodation space 115 may be formed inside the cover body 110. The bag accommodation space 115 may be disposed on the lower side of the coupling portion 120 in the direction of gravity, and may be disposed on the upper side of the dust suction module 190 in the direction of gravity.

[0168] The dust collecting section 170 may be provided in the bag accommodating space 115. Specifically, the bag supporting section 173 described later may be accommodated in the bag accommodating space 115 in a manner that allows access. In addition, the dust bag box 174 described later may be coupled to the bag accommodating space 115 in a manner that allows loading and unloading. In addition, the adapter 176 described later may be installed in the bag accommodating space 115. The bag accommodating space 115 may be connected to the first flow path 181, the second flow path 182, and the bypass flow path 183 described later. With the above-described configuration, the bag accommodating space 115 may provide a space in which the air and dust flowing in from the dust barrel 220 can flow and be captured in the dust bag 172.

[0169] In the present invention, the vacuum cleaner 200 can be placed on the outer wall surface 112 of the vacuum cleaner base station 100. As an example, the dust bucket 220 and the battery cover 230 of the vacuum cleaner 200 can be combined with the combination surface 121 of the vacuum cleaner base station 100. That is, the vacuum cleaner 200 can be placed on the first outer wall surface 112a.

[0170] At this time, the axis of the suction motor 214 may be formed to be perpendicular to the first outer wall surface 112a. That is, the axis of the suction motor 214 may be formed to be parallel to the ground.

[0171] An imaginary line passing through the dust container 220 may be formed perpendicular to the first outer wall surface 112 a .

[0172] The longitudinal axis C of the cover body 110 may be formed to be perpendicular to the ground and parallel to at least one of the first outer wall surface 112a, the second outer wall surface 112b, the third outer wall surface 112c, and the fourth outer wall surface 112d.

[0173] When the vacuum cleaner 200 is combined with the vacuum cleaner base station 100 , the axis of the suction motor 214 may intersect with the longitudinal axis of the vacuum cleaner base station 100 . That is, the rotation axis of the suction motor 214 may intersect with the longitudinal axis of the vacuum cleaner base station 100 .

[0174] In addition, when the vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the battery 240 can be arranged at a position farther from the ground than the rotation axis of the suction motor 214. With this configuration, the vacuum cleaner 200 can be stably supported by the vacuum cleaner base station 100.

[0175] When the vacuum cleaner 200 is combined with the vacuum cleaner base station 100, the imaginary line passing through the dust bucket 220 may intersect with the longitudinal axis of the vacuum cleaner base station 100. That is, the longitudinal axis of the dust bucket 220 may intersect with the longitudinal axis of the vacuum cleaner base station 100. At this time, the intersection point of the longitudinal axis of the dust bucket 220 and the longitudinal axis of the vacuum cleaner base station 100 may be located inside the cover body 110, more specifically, inside the flow path portion 180.

[0176] On the other hand, when the vacuum cleaner 200 is coupled to the vacuum cleaner base station 100, the handle 216 can be arranged at a position farther from the ground than the imaginary line passing through the dust bucket 220. With the above configuration, when the user holds the handle 216, the vacuum cleaner 200 can be coupled to or detached from the vacuum cleaner base station 100 by a simple action of the user moving the vacuum cleaner 200 in a direction parallel to the ground.

[0177] Below, refer to Figure 5, the coupling portion 120 of the vacuum cleaner base station 100 of the present invention is described.

[0178] The vacuum cleaner base station 100 may include a coupling portion 120 for coupling with the vacuum cleaner 200. Specifically, the coupling portion 120 may be disposed on the first outer wall surface 112a, and the main body 210, the dust bucket 220 and the battery cover 230 of the vacuum cleaner 200 may be coupled with the coupling portion 120.

[0179] The coupling portion 120 may include a coupling surface 121. The coupling surface 121 may be disposed on the side of the cover body 110. As an example, the coupling surface 121 may refer to a surface formed in the form of a groove recessed from the first outer wall surface 112a toward the inner side of the vacuum cleaner base station 100. That is, the coupling surface 121 may refer to a surface that forms a step with the first outer wall surface 112a.

[0180] The vacuum cleaner 200 may be combined with the joint surface 121. As an example, the joint surface 121 may contact the lower side of the dust bucket 220 and the battery cover 230 of the vacuum cleaner 200. Here, the lower side may refer to the surface facing the ground when the user uses the vacuum cleaner 200 or places the vacuum cleaner 200 on the ground.

[0181] As an example, the angle formed by the coupling surface 121 with respect to the ground may be a right angle. Thus, the space of the vacuum cleaner base station 100 when the vacuum cleaner 200 is coupled to the coupling surface 121 can be minimized.

[0182] As another example, the coupling surface 121 may be tilted to form a predetermined angle with respect to the ground. Thus, when the vacuum cleaner 200 is coupled to the coupling surface 121 , the vacuum cleaner base station 100 can be stably supported.

[0183] The joint surface 121 may be formed with a dust hole 121a so that air outside the cover body 110 can flow into the inside. The dust hole 121a may be formed in a hole shape corresponding to the shape of the dust barrel 220 so that dust in the dust barrel 220 flows into the dust collecting part 170. The dust hole 121a may be formed corresponding to the shape of the discharge cover 222 of the dust barrel 220. The dust hole 121a may be formed to communicate with the flow path part 180 described later.

[0184] The coupling portion 120 may include a dust bin guide surface 122. The dust bin guide surface 122 may be disposed on the first outer wall surface 112a. The dust bin guide surface 122 may be connected to the first outer wall surface 112a. In addition, the dust bin guide surface 122 may be connected to the coupling surface 121.

[0185] The dust bucket guide surface 122 may be formed in a shape corresponding to the outer side surface of the dust bucket 220. The front outer side surface of the dust bucket 220 may be combined with the dust bucket guide surface 122. Thus, the convenience of combining the vacuum cleaner 200 with the combination surface 121 can be provided.

[0186] On the other hand, a projection moving hole 122a may be formed on the dust barrel guide surface 122, and the pressing projection 151 described later may move linearly along the projection moving hole 122a. In addition, a gear box 155 for accommodating the gears of the cover opening unit 150 described later may be provided on the lower side of the dust barrel guide surface 122 in the direction of gravity. At this time, a guide space 122b in which the pressing projection 151 can move may be formed between the lower side of the dust barrel guide surface 122 and the upper side of the gear box 155. In addition, the guide space 122b may be connected to the first flow path 181 using the bypass hole 122c. That is, the projection moving hole 122a, the guide space 122b, the bypass hole 122c and the first flow path 181 may form a flow path. With the above configuration, when the dust collecting motor 191 is operated with the dust container 220 coupled to the coupling portion 120 , dust remaining in the dust container 220 and the dust container guide surface 122 can be sucked in through the flow path.

[0187] The coupling portion 120 may include a guide protrusion 123. The guide protrusion 123 may be disposed on the coupling surface 121. The guide protrusion 123 may protrude upward from the coupling surface 121. Two guide protrusions 123 may be disposed spaced apart from each other. The distance between the two spaced apart guide protrusions 123 may correspond to the width of the battery cover 230 of the vacuum cleaner 200. Thus, the convenience of coupling the vacuum cleaner 200 to the coupling surface 121 may be provided.

[0188] The coupling portion 120 may include a coupling portion side wall 124. The coupling portion side wall 124 may refer to a wall surface disposed on both sides of the coupling surface 121, which may be vertically connected to the coupling surface 121. The coupling portion side wall 124 may be connected to the first outer wall surface 112a. In addition, the coupling portion side wall 124 may form a surface connected to the dust bin guide surface 122. Thus, the vacuum cleaner 200 can be stably accommodated.

[0189] The coupling portion 120 may include a coupling sensor 125. The coupling sensor 125 may sense whether the cleaner 200 is coupled to the coupling portion 120.

[0190] The combination sensor 125 may also include a contact sensor. As an example, the combination sensor 125 may include a micro switch. In this case, the combination sensor 125 may be configured on the guide protrusion 123. Therefore, the battery cover 230 or the battery 240 of the vacuum cleaner 200 may contact the combination sensor 125 when combined between a pair of guide protrusions 123, and the combination sensor 125 may sense the combination of the vacuum cleaner 200.

[0191] On the other hand, the combined sensor 125 may also include a non-contact sensor. As an example, the combined sensor 125 may include an infrared sensor unit (IR sensor). In this case, the combined sensor 125 may be configured on the combined portion side wall 124. Thus, when the dust bin 220 or the main body 210 of the vacuum cleaner 200 passes through the combined portion side wall 124 and reaches the combined surface 121, the combined sensor 125 may sense the existence of the dust bin 220 or the main body 210.

[0192] When the vacuum cleaner 200 is coupled to the vacuum cleaner base station 100 , the coupling sensor 125 may face the dust container 220 or the battery cover 230 of the vacuum cleaner 200 .

[0193] The coupling sensor 125 may be a means for determining whether power is applied to the battery 240 of the cleaner 200 and whether the cleaner 200 is coupled.

[0194] The combination part 120 may include a suction part guide surface 126. The suction part guide surface 126 may be configured on the first outer wall surface 112a. The suction part guide surface 126 may be connected to the dust bin guide surface 122. The suction part 212 may be combined with the suction part guide surface 126. The shape of the suction part guide surface 126 may correspond to the shape of the suction part 212.

[0195] The coupling portion 120 may further include a fixing member access hole 127. The fixing member access hole 127 may be formed in a long hole shape along the coupling portion side wall 124 so that the fixing member 131 can enter and exit.

[0196] With this configuration, when the user couples the vacuum cleaner 200 to the coupling portion 120 of the vacuum cleaner base station 100, the main body 210 of the vacuum cleaner 200 can be stably arranged on the coupling portion 120 through the dust bucket guide surface 122, the guide protrusion 123, and the suction portion guide surface 126. Thus, the convenience of coupling the dust bucket 220 and the battery cover 230 of the vacuum cleaner 200 to the coupling surface 121 can be provided.

[0197] On the other hand, the vacuum cleaner base station 100 may further include a charging unit 128. The charging unit 128 may be disposed at the coupling unit 120. The charging unit 128 may be electrically connected to the vacuum cleaner 200 coupled to the coupling unit 120. The charging unit 128 may supply power to a battery of the vacuum cleaner 200 coupled to the coupling unit 120.

[0198] In addition, the vacuum cleaner base station 100 may further include a side door (not shown). The side door may be configured on the cover body 110. The side door may selectively expose the dust collecting unit 170 to the outside. Thus, the user may easily remove the dust bag 172 from the vacuum cleaner base station 100.

[0199] Reference Figure 6 , the fixing unit 130 of the present invention is described.

[0200] The vacuum cleaner base station 100 of the present invention may include a fixing unit 130. The fixing unit 130 may be disposed on the side wall 124 of the coupling portion. In addition, the fixing unit 130 may be disposed on the back of the coupling surface 121. The fixing unit 130 may fix the vacuum cleaner 200 coupled to the coupling surface 121. Specifically, the fixing unit 130 may fix the dust bucket 220 and the battery cover 230 of the vacuum cleaner 200 coupled to the coupling surface 121.

[0201] The fixing unit 130 may include a fixing member 131 for fixing the dust bucket 220 and the battery cover 230 of the vacuum cleaner 200, and a fixing motor 133 for driving the fixing member 131. In addition, the fixing unit 130 may further include a fixing coupling 135 for transmitting the power of the fixing motor 133 to the fixing member 131.

[0202] The fixing member 131 may be disposed on the joint sidewall 124 and is configured to be able to reciprocate on the joint sidewall 124 to fix the dust bin 220. Specifically, the fixing member 131 may be accommodated inside the fixing member access hole 127.

[0203] The fixing members 131 may be respectively disposed on both sides of the coupling portion 120. As an example, the two fixing members 131 may be symmetrically disposed in pairs with the coupling surface 121 as the center.

[0204] The fixing part motor 133 may provide power to move the fixing member 131 .

[0205] The fixing part coupling 135 may convert the rotation force of the fixing part motor 133 into the reciprocating movement of the fixing member 131 .

[0206] The fixed seal 136 can be configured on the dust bin guide surface 122 to airtightly seal the dust bin 220 when the dust collector 200 is combined. Through the above-mentioned configuration, when the dust bin 220 of the dust collector 200 is combined, the weight of the dust collector 200 can pressurize the fixed seal 136, and the dust bin 220 and the dust bin guide surface 122 can be sealed.

[0207] The fixed seal 136 may be disposed on an imaginary extension line of the fixed member 131. With the above configuration, when the fixed portion motor 133 is operated and the fixed member 131 presses the dust container 220, the periphery of the dust container 220 at the same height may be sealed.

[0208] According to an embodiment, the fixed seal 136 may be disposed on the dust container guide surface 122 in a bent line form corresponding to the configuration of the cover opening unit 150 described later.

[0209] Thus, when the main body 210 of the vacuum cleaner 200 is disposed on the coupling part 120, the fixing unit 130 can fix the main body 210 of the vacuum cleaner 200. Specifically, when the coupling sensor 125 senses that the main body 210 of the vacuum cleaner 200 is coupled to the coupling part 120 of the vacuum cleaner base station 100, the fixing part motor 133 can fix the main body 210 of the vacuum cleaner 200 by moving the fixing member 131.

[0210] Thus, dust will not remain in the dust barrel, thereby improving the suction power of the vacuum cleaner. In addition, the malodor caused by the residue can be removed by preventing dust from remaining in the dust barrel.

[0211] Below, refer to Figure 7 and Figure 8 , the door unit 140 of the present invention is described.

[0212] The vacuum cleaner base station 100 of the present invention may include a door unit 140. The door unit 140 may be configured to be able to open and close the dust passage hole 121a.

[0213] The door unit 140 may include a door 141 , a door motor 142 , and a door arm 143 .

[0214] The door 141 may be hinge-coupled to the coupling surface 121 and may open and close the dust passing hole 121a. The door 141 may include a door body 141a.

[0215] The door body 141a may be formed in a shape capable of blocking the dust passing hole 121a. As an example, the door body 141a may be formed in a shape similar to a disk.

[0216] Based on the state in which the door body 141a blocks the dust passage hole 121a, a hinge portion may be disposed on the upper side of the door body 141a, and an arm coupling portion 141b may be disposed on the lower side of the door body 141a.

[0217] The door body 141a may be formed in a form that can airtightly seal the dust passage hole 121a. As an example, the outer side surface of the door body 141a exposed to the outside of the vacuum cleaner base station 100 is formed to have a diameter corresponding to the diameter of the dust passage hole 121a, and the inner side surface disposed inside the vacuum cleaner base station 100 is formed to have a diameter greater than the diameter of the dust passage hole 121a. In addition, a step may be formed between the outer side surface and the inner side surface. On the other hand, at least one protruding reinforcing rib may be formed on the inner side surface, and the reinforcing rib is used to connect the hinge portion and the arm joint portion 141b and to increase the support force of the door body 141a.

[0218] The hinge part may be a mechanism for hinge-joining the door 141 to the joint surface 121. The hinge part may be disposed at an upper end portion of the door body 141a and joined to the joint surface 121.

[0219] The arm coupling part 141b may be a mechanism for rotatably coupling the door arm 143. The arm coupling part 141b may be disposed at the lower side of the door body 141a and may be rotatably coupled to the door body 141a, and the door arm 143 may be rotatably coupled to the arm coupling part 141b.

[0220] With the above-described configuration, when the door arm 143 pulls the door body 141a in a state where the door 141 closes the dust passage hole 121a, the door body 141a can rotate and move toward the inside of the vacuum cleaner base station 100 with the hinge portion as an axis, and the dust passage hole 121a can be opened. On the other hand, when the door arm 143 pushes the door body 141a in a state where the dust passage hole 121a is opened, the door body 141a can rotate and move toward the outside of the vacuum cleaner base station 100 with the hinge portion 141b as an axis, and the dust passage hole 121a can be blocked.

[0221] On the other hand, in a state where the cleaner 200 is coupled to the cleaner base station 100 and the discharge cover 222 is separated from the dust bucket body 210, the door 141 may contact the discharge cover 222. In addition, the discharge cover 222 may rotate in conjunction with the door 141 as the door 141 rotates.

[0222] The door motor 142 may provide power to rotate the door 141. Specifically, the door motor 142 may rotate the door arm 143 in a positive direction or a negative direction. Here, the positive direction may refer to a direction in which the door arm 143 pulls the door 141. Therefore, when the door arm 143 rotates in the positive direction, the dust passage hole 121a may be opened. In addition, the negative direction may refer to a direction in which the door arm 143 pushes the door 141. Therefore, when the door arm 143 rotates in the negative direction, at least a portion of the dust passage hole 121a may be blocked. The positive direction may be a direction opposite to the negative direction.

[0223] The door arm 143 can connect the door 141 and the door motor 142 , and open and close the door 141 using power generated by the door motor 142 .

[0224] As an example, the door arm 143 may include a first door arm 143a and a second door arm 143b. One end of the first door arm 143a may be combined with the door motor 142. The first door arm 143a may be rotated by the power of the door motor 142. The other end of the first door arm 143a may be combined with the second door arm 143b in a rotatable manner. The first door arm 143a may transmit the force received from the door motor 142 to the second door arm 143b. One end of the second door arm 143b may be combined with the first door arm 143a. The other end of the second door arm 143b may be combined with the door 141. The second door arm 143b may open and close the dust passage hole 121a by pushing or pulling the door 141.

[0225] The door unit 140 may further include a door opening and closing sensor 144. The door opening and closing sensor 144 may be disposed inside the housing 110 and sense whether the door 141 is in an open state.

[0226] As an example, the door opening and closing sensors 144 may be disposed at both ends of the rotational movement region of the door arm 143. As another example, the door opening and closing sensors 144 may be disposed at both ends of the movement region of the door 141.

[0227] Thus, when the door arm 143 moves to the preset door opening position DP1 or the door 141 is opened to a specified position, the door opening and closing sensor 144 can sense that the door has been opened. In addition, when the door arm 143 moves to the preset door blocking position DP2 or the door 141 is opened to a specified position, the door opening and closing sensor 144 can sense that the door has been opened.

[0228] The door opening / closing sensor 144 may include a contact sensor. As an example, the door opening / closing sensor 144 may include a micro switch.

[0229] On the other hand, the door opening and closing sensor 144 may include a non-contact sensor. As an example, the door opening and closing sensor 144 may include an infrared sensor (IR sensor).

[0230] With this configuration, the door unit 140 can connect the outside of the first outer wall surface 112 a with the flow path portion 180 and / or the dust collecting portion 170 by selectively opening and closing at least a portion of the joint surface 121 .

[0231] The door unit 140 may be opened together when the discharge cover 222 of the cleaner 200 is opened. In addition, when the door unit 140 is closed, the discharge cover 222 of the cleaner 200 may be closed together in conjunction therewith.

[0232] When the dust in the dust bucket 220 of the vacuum cleaner 200 is removed, the door motor 142 can rotate the door 141 to couple the discharge cover 222 to the dust bucket body 221. Specifically, the door motor 142 can rotate the door 141 with the hinge part 141b as the reference by rotating the door 141, and the door 141 rotating with the hinge part 141b as the reference can push the discharge cover 222 toward the dust bucket body 221.

[0233] Below, refer to Fig. 9 The lid opening unit 150 of the present invention will be described.

[0234] The vacuum cleaner base station 100 of the present invention may include a cover opening unit 150. The cover opening unit 150 may be disposed at the coupling portion 120, and may open the discharge cover 222 of the vacuum cleaner 200.

[0235] The cover opening unit 150 may include a pressing protrusion 151 , a cover opening motor 152 , a cover opening gear 153 , a support plate 154 , and a gear box 155 .

[0236] The pressing protrusion 151 may move to pressurize the coupling rod 222 c when the cleaner 200 is coupled.

[0237] The pressing protrusion 151 may be disposed on the dust barrel guide surface 122. Specifically, a protrusion moving hole may be formed on the dust barrel guide surface 122, and the pressing protrusion 151 may be exposed to the outside through the protrusion moving hole.

[0238] The pressing protrusion 151 can be arranged at a position where the coupling rod 222c can be pressed when the vacuum cleaner 200 is combined. That is, the coupling rod 222c can be arranged on the protrusion moving hole. In addition, the coupling rod 222c can be arranged on the moving area of ​​the pressing protrusion 151.

[0239] The pressing protrusion 151 may reciprocate linearly to press the coupling rod 222c. Specifically, the pressing protrusion 151 may be guided to move linearly by being coupled to the gear box 155. The pressing protrusion 151 may be coupled to the cover opening gear 153 and move together with the movement of the cover opening gear 153.

[0240] The cover opening motor 152 can provide power to move the pressing protrusion 151. Specifically, the cover opening motor 152 can rotate the motor shaft (not shown) in a positive direction or a negative direction. Here, the positive direction can refer to the direction in which the pressing protrusion 151 presses the coupling rod 222c. In addition, the negative direction can refer to the direction in which the pressing protrusion 151 pressing the coupling rod 222c returns to the original position. The positive direction can be the opposite direction to the negative direction.

[0241] The cover opening gear 153 can be combined with the cover opening motor 152, and the pressing protrusion 151 can be moved by the power of the cover opening motor 152. Specifically, the cover opening gear 153 can be accommodated in the gear box 155. The driving gear 153a of the cover opening gear 153 can be combined with the motor shaft of the cover opening motor 152 to obtain power. The driven gear 153b of the cover opening gear 153 can be combined with the pressing protrusion 151 to move the pressing protrusion 151. As an example, the driven gear 153b can be set in a rack form and meshed with the driving gear 153a, and can receive power from the driving gear 153a.

[0242] At this time, a torsion spring 222d may be provided on the discharge cover 222. The discharge cover 222 may be rotated by the elastic force of the torsion spring 222d to a predetermined angle or more and supported at the rotated position. Thus, the discharge cover 222 may be opened, so that the dust passing hole 121a and the inside of the dust bin 220 are connected.

[0243] The gear box 155 may be provided inside the housing 110 and disposed on the lower side of the coupling portion 120 in the gravity direction, and accommodate the cover opening gear 153 inside.

[0244] The gear box 155 may be provided with a cover opening sensor 155f. In this case, the cover opening sensor 155f may also include a contact sensor. As an example, the cover opening sensor 155f may include a micro switch. On the other hand, the cover opening sensor 155f may also include a non-contact sensor. As an example, the cover opening sensor 155f may include an infrared sensor.

[0245] At least one cover opening sensor 155f may be disposed on the inner side or outer side of the gear box 155. For example, one cover opening sensor 155f may be disposed on the inner side of the gear box 155. At this time, the cover opening sensor 155f may sense that the pressing protrusion 151 is located at the initial position.

[0246] Therefore, according to the present invention, the user can open the dust container 220 through the cover opening unit 150 without additionally opening the discharge cover 222 of the cleaner, thereby improving convenience.

[0247] In addition, since the discharge cover 222 is opened when the cleaner 200 is coupled to the cleaner base station 100 , it is possible to prevent dust from being scattered.

[0248] Figures 10 to 23 A diagram for explaining the configuration and arrangement of a dust collecting unit in a vacuum cleaner base station according to an embodiment of the present invention is shown.

[0249] Below, refer to Figures 10 to 23 Description of the Dust Collecting Unit 170

[0250] The vacuum cleaner base station 100 may include a dust collecting unit 170. The dust collecting unit 170 may be disposed inside the housing 110. The dust collecting unit 170 may be disposed in the bag accommodating space 115. Furthermore, the dust collecting unit 170 may be disposed on the upper side of the dust collecting motor 191 in the direction of gravity.

[0251] The dust collecting part 170 can collect dust inside the dust bucket 220 of the vacuum cleaner 200. Specifically, when the dust collecting motor 191 is operated in a state where the vacuum cleaner 200 is combined with the vacuum cleaner base station 100 and the interior of the dust bucket 220 is connected to the flow path part 180, the dust inside the dust bucket 220 can flow along the flow path part 180 and be captured in the dust collecting part 170.

[0252] On the other hand, in a common vacuum cleaner base station, dust is captured in a dust bag without being separated from the air, so a part of the dust may flow into the dust collecting motor side. Therefore, the dust flowing into the dust collecting motor may cause a malfunction of the dust collecting motor.

[0253] In order to solve this problem, a prefilter or the like may be arranged on the flow path. However, when the dust is filtered only by the prefilter, the prefilter is clogged with a large amount of dust, which may reduce the suction force of the dust collecting motor.

[0254] In order to solve this problem, the dust collecting unit 170 of the vacuum cleaner base station 100 of the present invention includes a dust separating unit 171 to separate and capture dust from the air flowing in through the flow path unit 180 .

[0255] Specifically, the dust collecting portion 170 may include a dust separating portion 171 , a dust bag 172 , a bag supporting portion 173 , a dust bag box 174 , a pre-filter 175 , and a coupler 176 .

[0256] The dust separator 171 may separate dust from the air flowing into the dust container 220 .

[0257] The dust separator 171 may be disposed on the upper side of the dust bag 172, the bag support 173, the dust bag box 174, and the adapter 176. That is, the dust bag box 174, the bag support 173, the dust bag box 174, and the adapter 176 may be disposed on the lower side of the dust separator 171. The dust separator 171 may be in contact with the dust bag box 174.

[0258] The dust separation unit 171 may be disposed on the longitudinal axis C of the cleaner base station 100 .

[0259] The dust separating part 171 may include a dust separating part housing 171 a .

[0260] The dust separating portion housing 171 a may form an external appearance of the dust separating portion 171 .

[0261] A cyclone may be provided inside the dust separation portion housing 171a. That is, a cyclone portion 171b may be provided inside the dust separation portion housing 171a.

[0262] In addition, a dust passing pipe 171c may be formed in the dust separation unit housing 171a. For example, a flow path through which dust can pass may be formed on the lower side of the dust separation unit housing 171a.

[0263] The lower side of the dust separation unit 171 may be formed to be inclined at a predetermined angle relative to the ground. That is, the lower side of the dust separation unit housing 171a may be formed to be inclined at a predetermined angle relative to the ground. The lower side of the dust separation unit 171 may be formed to be gradually lowered from one side to the other side from the ground. For example, the height of the dust separation unit housing 171a from the ground may gradually become lower as it approaches the rear from the front end of the dust bag box 174.

[0264] A seal 171d may be provided on the lower side of the dust separation portion housing 171a so as to contact the dust bag box 174. For example, the seal 171d may be configured in a quadrilateral shape surrounding the outer contour of the dust passage pipe 171c.

[0265] The dust separator 171 may communicate with the first flow path 181. The dust separator 171 may separate dust sucked into the interior through the first flow path 181. The space inside the dust separator 171 may communicate with the inner space of the dust bag box 174. The space inside the dust separator 171 may communicate with the space inside the bag support 173.

[0266] For example, the dust separator 171 may be provided with at least one cyclone 171b capable of separating dust by cyclone flow. Therefore, the air and dust flowing in through the first flow path 181 flow in a spiral along the inner circumference of the dust separator 171. Thus, a cyclone flow may be generated in the inner space of the dust separator 171.

[0267] On the other hand, in this embodiment, the cyclone part 171b may be provided with a cylindrical mesh. Here, the axial direction of the mesh may be arranged parallel to the ground. With the above-described configuration, when the cyclone part 171b is pulled on the side of the vacuum cleaner base station 100, the cyclone part 171b may be separated from the dust collecting part 170. Therefore, according to this embodiment, the user can easily separate the cyclone part 171b and clean the mesh.

[0268] In addition, the dust separation unit 171 may include a dust passage pipe 171c that guides the dust separated from the cyclone unit 171b to the dust bag 172. The dust passage pipe 171c may be formed downward from one axial side of the cyclone unit 171b. That is, the dust passage pipe 171c may be formed at the lower side of the dust separation unit housing 171a. Therefore, the flow path formed in the dust passage pipe 171c may allow the internal space of the dust bag box 174 and the bag support 173 to communicate with the cyclone unit 171b.

[0269] The dust separation unit 171 may further include a secondary cyclone for separating dust from the air discharged from the cyclone again. At this time, the secondary cyclone may be located inside the cyclone to minimize the size of the dust separation unit 171.

[0270] The dust separator 171 is communicated with the first flow path 181 and is constructed based on the principle of a dust collector using centrifugal force to separate dust flowing into the housing 110 through the dust passage hole 121 a .

[0271] The dust bag 172 may be disposed inside the housing 110. The dust bag 172 may be disposed on the lower side of the dust separation portion 171 in the gravity direction.

[0272] The dust bag 172 may be formed of an impermeable material. For example, the dust bag 172 may include a rolled plastic (not shown). With the above-described configuration, when the dust bag 172 is sealed or joined, dust or odor trapped inside the dust bag 172 can be prevented from leaking out of the dust bag 172.

[0273] The dust bag 172 can be installed on the housing 110 using a dust bag box 174. The dust bag 172 can be replaced by the dust bag box 174 as needed. That is, the dust collecting unit 170 can be defined as a consumable component. The dust bag 172 can be enlarged in size due to the suction force (negative pressure) generated when the dust collecting motor 191 is running when the dust bag 172 is installed on the housing 110.

[0274] At this time, the dust bag 172 in the expanded state may be accommodated inside the bag support portion 173. That is, when the dust collecting motor 191 is operated, the dust bag 172 may expand inside the bag support portion 173. Thereafter, the dust bag 172 in the expanded state may be supported by the bag support portion 173 so that the shape is maintained.

[0275] The dust bag 172 may store the dust separated by the dust separation part 171. The upper region of the dust bag 172 may be cut and joined by the joiner 176. The dust bag 172 may be separated from the bag support part 173 in a state where the upper region is cut and joined.

[0276] With this configuration, the user does not need to additionally bundle a dust bag or the like that collects dust, and thus the user's convenience can be improved.

[0277] On the other hand, when the dust bag is a common roll plastic type, the dust bag may be pulled toward the dust collecting motor side to be flattened when the dust collecting motor is running. Therefore, the inner space of the dust bag becomes narrower when the dust collecting motor is running, making it difficult to capture dust in the dust bag.

[0278] In order to solve this problem, the dust collecting part 170 of the vacuum cleaner base station 100 according to an embodiment of the present invention may be additionally provided with a bag supporting part 173 , so that the dust bag can be stably unfolded.

[0279] The bag support part 173 may support the dust bag 172. The bag support part 173 may accommodate the dust bag 172 inside when the dust bag 172 is expanded. The bag support part 173 may support the outer shape of the expanded dust bag 172.

[0280] The bag support part 173 may be disposed at the lower side of the dust separation part 171. With the above-described configuration, the dust separated in the dust separation part 171 may be collected inside the bag support part 173.

[0281] Bag support part 173 may be disposed at the lower side of dust bag box 174. With the above configuration, when dust bag 172 expands from dust bag box 174 to the lower side, at least a portion of dust bag 172 may be accommodated inside bag support part 173.

[0282] The bag support part 173 may be disposed on the lower side of the adapter 176. With the above-described configuration, the expanded dust bag 172 is engaged and separated by the adapter 176, and falls downward due to gravity and is accommodated in the bag support part 173.

[0283] Specifically, the bag support portion 173 may include a support portion body 173 a and suction holes 173 b .

[0284] A space may be formed between the lower side of the support portion body 173a and the lower side of the bag receiving space 115. The space may provide a path for transmitting the suction force of the dust collecting motor 191.

[0285] With the above configuration, when the dust collecting motor 191 is operated, the air in the bag accommodation space can be sucked into the dust collecting motor 191 by the suction force of the dust collecting motor 191, and negative pressure can be formed in the bag accommodation space to expand the dust bag 172.

[0286] The support body 173a may be formed to accommodate the dust bag 172 when the dust bag 172 is expanded. For example, the support body 173a may be formed in a cylindrical shape, the upper side of the support body 173a may be open, and the lower side of the support body 173a may be formed in a shape in which at least a part is blocked.

[0287] As another example, the support body 173a may be formed in a hexahedral shape, the upper side of the support body 173a may be open, and the front surface of the support body 173a may be open. With the above configuration, the dust bag 172 can be removed through the open front surface.

[0288] At least a portion of the dust bag 172 may be disposed on the upper side of the support portion body 173a. When the dust bag 172 expands, the dust bag 172 expands downward to fill the inner space of the support portion body 173a.

[0289] A plurality of adsorption holes 173b may be formed in the support body 173a. For example, a plurality of adsorption holes 173b may be formed along the outer peripheral surface of the support body 173a. In addition, at least one adsorption hole 173b may be formed on the lower side of the support body 173a. With the above-described configuration, when the dust collecting motor 191 is running, the air inside the support body 173a may flow to the outside of the support body 173a through the adsorption holes 173b. In addition, when the dust bag 172 is expanded inside the support body 173a, a negative pressure toward the outside of the support body 173a may be applied to the dust bag 172, and the dust bag 172 may expand to be in close contact with the inner peripheral surface and the lower side of the support body 173a. That is, the dust bag 172 may expand along the internal shape of the bag support portion 173.

[0290] In particular, when the plurality of adsorption holes 173 b are formed to maintain a predetermined interval, a uniform negative pressure can be applied to the entire dust bag 172 , so that the dust bag 172 can be uniformly expanded and maintain the expanded state.

[0291] On the other hand, the bag support portion 173 may be configured to be able to be drawn out from the cover body 110 .

[0292] Specifically, the bag support portion 173 may be disposed in the bag accommodation space 115 formed inside the housing 110. At this time, the bag support portion 173 may have a structure for guiding the linear movement of the bag support portion 173.

[0293] With the above configuration, the user can open the side door (not shown) of the vacuum cleaner base station 100 and then pull the bag support 173 to draw the dust bag 172 out of the housing 110. Thus, according to the present invention, the user can easily take out and discard the dust bag.

[0294] On the other hand, in the case of a roll-up plastic type vacuum cleaner base station, if the dust bag as a consumable item is completely consumed, the dust bag needs to be replaced. In this case, the user can directly insert and install the dust bag inside the cover of the vacuum cleaner base station, but there is a hidden danger of malfunction during the process of the user opening the inside of the vacuum cleaner base station. In addition, if the dust bag is installed incorrectly, there is a problem that dust is collected when the dust bag is not unfolded, causing the dust to fly.

[0295] In order to solve this problem, in the present invention, the user can easily supply the dust bag through the dust bag box 174 in a manner of only replacing the box.

[0296] The dust bag box 174 may be detachably combined with the cover body 110 and supply the dust bag 172 .

[0297] The dust bag box 174 may be detachably coupled to the housing 110. Specifically, the dust bag box 174 is detachably coupled to a box coupling space 174e formed between the dust separator 171 and the adapter 176.

[0298] At this time, in the present invention, the box combination space 174e can be formed with different heights in the up and down directions. For example, in the box combination space 174e, the height of the dust bag box 174 from the outside into the inside of the cleaner base station 100 can be greater than the height of the rear.

[0299] When the dust bag box 174 is coupled to the housing 110, if the user pulls the dust bag box 174 to the outside of the cleaner base station 100, the dust bag box 174 can be separated from the housing 110. With the above configuration, the user can easily attach and detach the dust bag box 174 to the housing.

[0300] The dust bag box 174 may be provided with a dust bag 172. For example, at least a portion of a dust bag 172 in a rolled plastic form may be combined with the dust bag box 174, and the dust bag 172 may expand toward the bag support portion 173 as the dust collecting motor 191 operates. In addition, when the dust bag 172 is engaged with the action of the later-described engagement device 176, a portion of the dust bag 172 may be separated from the dust bag box 174. With the above-described configuration, the user does not need to additionally bundle a dust bag that collects dust, etc., thereby improving the convenience of the user.

[0301] The dust bag box 174 may be disposed at a lower side of the dust separation portion 171. For example, an upper side surface of the dust bag box 174 and a lower side surface of the dust separation portion 171 may contact each other.

[0302] The dust bag box 174 may be disposed on the upper side of the adapter 176. For example, the lower side of the dust bag box 174 and the upper side of the adapter 176 may contact each other.

[0303] The dust bag box 174 includes a box housing 174a, an upper seal 174b, and a lower seal 174c.

[0304] The box housing 174a forms the appearance of the dust bag box 174, and the dust bag 172 can be accommodated in the box housing 174a. As an example, the box housing 174a can be formed so that a space for accommodating the dust bag 172 is formed inside by combining the upper housing and the lower housing. In this case, the box housing 174a can be in the form of a rectangular tube as a whole (see FIG. 14 ). Fig.18 ). That is, a space 174f through which air can flow may be formed inside (in the center) of the box housing 174a. At least a portion of the dust bag 172 may expand through the space 174f.

[0305] The box housing 174a may be formed with a bag supply hole 174d through which the dust bag 172 can be drawn out. As an example, the bag supply hole 174d may be formed on the inner peripheral surface of the box housing 174a. With the above-described configuration, when the dust bag 172 is drawn out, the space 174f formed in the center of the box housing 174a may be blocked by the dust bag 172. Therefore, if the dust collecting motor 191 is operated, the dust bag 172 may be sucked toward the dust collecting motor 191 and expand.

[0306] The box housing 174a may be formed at a prescribed height. The height of the box housing 174a may be lower than the front end height of the box coupling space 174e. The height of the box housing 174a is the same as the rear end height of the box coupling space 174e.

[0307] By the above-mentioned formation, box housing 174a can be easily inserted into the front end of box combination space 174e. In addition, when box housing 174a is combined in the box combination space 174e, box housing 174a can contact and be supported on the lower side of dust separation portion 171 and / or the upper side of adapter 176.

[0308] On the other hand, as described above, when there is a space between the dust bag box and the surrounding structure, or when the dust bag box is configured to be attachable and detachable, there is a problem that dust contained in the air may be scattered through the space where the dust bag box is connected.

[0309] In order to solve this problem, the vacuum cleaner base station 100 according to an embodiment of the present invention may provide at least one sealing member 174 b , 174 c on the dust bag box 174 to seal the gap that may cause dust to fly.

[0310] That is, an upper seal 174b may be provided on the upper side of the box housing 174a. For example, the upper seal 174b may be configured in a quadrilateral shape with the space 174f formed in the center of the box housing 174a as the center and surrounding the outer contour of the space 174f. The upper seal 174b can block the leakage of foreign matter. With the above-mentioned configuration, the foreign matter separated from the dust separation unit 171 can be captured inside the dust bag 172 without leaking to the outside.

[0311] A lower seal 174c may be provided on the lower side of the box housing 174a. For example, the lower seal 174c may be formed in a quadrilateral shape with the space 174f formed in the center of the box housing 174a as the center and surrounding the outer contour of the space 174f. The lower seal 174c may block the leakage of foreign matter in the dust bag box 174. With the above-described configuration, it is possible to prevent foreign matter that has passed through the dust bag box 174 from leaking between the dust bag box 174 and the adapter 176.

[0312] The dust collecting unit 170 may further include a pre-filter 175. The pre-filter 175 may be disposed on the second flow path 182 and may separate foreign matter from the air flowing in the second flow path 182. For example, the pre-filter 175 may be disposed on the inlet side of the second flow path 182 and may separate dust and the like contained in the air passing through the dust separation unit 171. The above-described configuration has the effect of preventing foreign matter from flowing into the dust collecting motor 191.

[0313] The pre-filter 175 may be detachably coupled to the second flow path 182. The pre-filter 175 may be detachably coupled to the second flow path 182 from the front of the cleaner base station 100.

[0314] The dust collection portion 170 may further include a coupler 176 .

[0315] The adapter 176 may be disposed on the lower side of the dust bag box 174. For example, the upper side of the adapter 176 may contact the lower side of the dust bag box 174. With the above-described configuration, the adapter 176 can guide the dust bag box 174 to be attached and detached.

[0316] The adapter 176 may be disposed on the upper side of the bag support portion 173. For example, the lower side of the adapter 176 may contact the upper side of the bag support portion 173.

[0317] The jointer 176 can cut and join the upper area of ​​the dust bag 172 where dust is trapped. Specifically, the jointer 176 can gather in the central area of ​​the dust bag 172 and hot-line join the upper area of ​​the dust bag 172. For example, the jointer 176 can include a first joining member (not shown) and a second joining member (not shown). The first joining member (not shown) can be moved in a first direction by a first joining drive unit, and the second joining member (not shown) can be moved in a second direction perpendicular to the first direction by a second joining drive unit.

[0318] With the above configuration, dust collected from the outside can be collected inside the roll plastic, and the roll plastic can be automatically joined. Therefore, the user does not need to additionally bundle a dust bag or the like that collects dust, thereby improving the convenience of the user.

[0319] The adapter 176 includes an adapter housing 176a, a seal 176b, and a cassette sensing sensor 176c.

[0320] The adapter housing 176a forms the appearance of the adapter. The adapter housing 176a may be disposed on the cover 110. For example, the adapter housing 176a may be fixedly coupled to the cover 110.

[0321] The upper side of the adapter 176 may be formed to be inclined at a predetermined angle relative to the ground. That is, the upper side of the adapter housing 176a may be formed to be inclined at a predetermined angle relative to the ground. Specifically, the upper side of the adapter 176 may be formed to gradually increase in height from the ground from one side to the other side. For example, the upper side of the adapter housing 176a may be formed to gradually increase in height from the front end of the dust bag box 174 to the rear.

[0322] By the above-described configuration, the entrance of the box coupling space 174e into which the dust bag box 174 is inserted is formed to be wider, and when the dust bag box 174 is fully inserted into the box coupling space 174e, the adapter 176 can support the dust bag box 174.

[0323] A seal 176b may be disposed on the upper side of the adapter housing 176a to contact the dust bag box 174. For example, the seal 176b may be disposed in a quadrilateral shape surrounding the outer contour of the flow path portion 180 with the flow path portion 180 as the center. The seal 176b may block foreign matter from leaking from between the adapter 176 and the dust bag box 174.

[0324] On the other hand, the seal may not be able to seal when the dust bag box 174 is not installed in the correct position of the cover body 110. In this case, if the dust collecting motor 191 is running, a large amount of dust will fly, and it may also cause the internal components of the vacuum cleaner base station 100 to malfunction.

[0325] That is, it is necessary to prevent the erroneous installation of the dust bag box 174 and sense whether the dust bag box 174 is accurately installed.

[0326] To this end, the vacuum cleaner base station 100 according to an embodiment of the present invention further includes a box sensing sensor 176c.

[0327] The box sensing sensor 176c may be disposed on the upper side of the adapter housing 176a. For example, the upper side of the adapter housing 176a may include a front upper side, a rear upper side, a left upper side, and a right upper side. Here, the front upper side may refer to a surface of the upper side that is disposed in front of the vacuum cleaner base station into which the dust bag box is inserted, the rear upper side may refer to a surface of the upper side that is disposed behind the vacuum cleaner base station, the left upper side may refer to a surface of the upper side that is disposed on the left side of the vacuum cleaner base station, and the right upper side may refer to a surface of the upper side that is disposed on the right side of the vacuum cleaner base station.

[0328] At this time, the box sensing sensor 176c can be arranged on the upper left side or the upper right side of the adapter housing 176a. In addition, the box sensing sensor 176c can be arranged in the middle position along the front-back direction of the vacuum cleaner base station 100. In addition, the box sensing sensor 176c can be arranged at a position further outside than the sealing member 176b.

[0329] By configuring as described above, the box sensing sensor 176c can be configured so as not to interfere with the moving paths of the first engaging member (not shown) and the second engaging member (not shown).

[0330] The box sensing sensor 176c can sense whether the dust bag box 174 is connected or not. At this time, the box sensing sensor 176c can also include a contact sensor. As an example, the box sensing sensor 176c can include a micro switch.

[0331] With the above-described configuration, if the dust bag box 174 is inserted into the box coupling space 174e, the box sensing sensor 176c and the dust bag box 174 may come into contact with each other, and it may be sensed that the dust bag box 174 has been coupled.

[0332] On the other hand, although not shown, the dust collecting unit 170 may further include a dust amount sensor (not shown). The dust amount sensor may measure the amount of dust in the dust bag 172 .

[0333] The cleaner base station 100 may include a flow path unit 180. The flow path unit 180 may connect the cleaner 200, the dust collecting unit 170, and the dust collecting motor 191.

[0334] The flow path portion 180 may include a first flow path 181 , a second flow path 182 , and a bypass flow path 183 .

[0335] The first flow path 181 may connect the dust bucket 220 and the dust collecting part 170 of the vacuum cleaner 200. The first flow path 181 may be disposed at the rear side of the joint surface 121. The first flow path 181 may refer to a space between the dust bucket 220 and the dust collecting part 170 of the vacuum cleaner 200. The first flow path 181 may be a space formed from the dust through hole 121a to the rear side, or may be a flow path formed from the dust through hole 121a to the bottom and through which dust and air can flow.

[0336] For example, the first flow path 181 may include: a first area 181a, which is connected to the internal space of the dust bin 220 when the vacuum cleaner 200 is combined with the vacuum cleaner base station 100 and the dust is opened through the hole 121a; and a second area 181b, which connects the first area 181a with the bag accommodating space 115 (or the internal space of the dust collecting part 170). At this time, it can be configured that the formation direction of the first area 181a is substantially parallel to the axial direction (length direction) of the dust bin. In addition, the direction formed by the second area 181b can be parallel to the longitudinal axis C of the cover body 110. At this time, the first area 181a and the second area 181b can form a specified angle. Through the above-mentioned configuration, the suction force of the dust collecting motor 191 can be minimized in the first area 181a and the second area 181b.

[0337] Therefore, when the dust collecting motor 191 is operated, the dust in the dust container 220 of the cleaner 200 may flow toward the dust collecting portion 170 through the first flow path 181 .

[0338] The second flow path 182 may connect the dust collecting part 170 and the dust suction module 190. Specifically, the second flow path 182 may be a flow path that connects the upper side of the dust collecting part 170 and the upper side of the dust suction module 190.

[0339] According to this configuration, the air that has passed through the dust collecting portion 170 can be guided to the dust collecting motor 191 by the second flow path 182 .

[0340] The bypass flow path 183 may connect the bag support portion 173 and the dust collecting motor 191 in a flow path manner.

[0341] The bypass flow path 183 can connect the bag accommodation space 115 and the inner space of the dust suction module 190. For example, the bypass flow path 183 can be a flow path formed in the gravity direction to connect the bag accommodation space 115 and the dust suction module 190. With the above-mentioned configuration, the bypass flow path 183 can guide the air existing in the bag accommodation space 115 to the dust collection motor 191.

[0342] The second flow path 182 and the bypass flow path 183 may be connected to each other and connected to the dust suction module 190. As an example, the second flow path 182 may be connected to the bypass flow path 183, and the bypass flow path 183 may be connected to the dust suction module 190. As another example, the second flow path 182 may be connected to the bypass flow path 183, and the second flow path 182 may be connected to the dust suction module 190. Thus, the second flow path 182 and the bypass flow path 183 may be connected to the dust collecting part 170 and the dust collecting motor 191 in the form of flow paths.

[0343] With the above-described configuration, there is an effect of being able to suck in external air while maintaining the shape of the dust bag by operating the dust collecting motor 191 .

[0344] The cleaner base station 100 may include a dust suction module 190. The dust suction module 190 may include a dust collection motor 191.

[0345] The dust collecting motor 191 may be disposed at the lower portion of the dust collecting portion 170. The dust collecting motor 191 may generate suction force in the flow path portion 180. Thus, the dust collecting motor 191 may provide suction force capable of sucking dust in the dust container 220 of the cleaner 200.

[0346] The dust collecting motor 191 can generate suction by rotating. As an example, the dust collecting motor 191 can be formed in a shape similar to a cylinder, and can generate suction when rotating around the rotation axis. At this time, the direction of the rotation axis of the dust collecting motor 191 can be configured to be perpendicular to the ground.

[0347] on the other hand, Fig.24A block diagram for explaining a control structure in a vacuum cleaner base station according to an embodiment of the present invention is shown.

[0348] Below, refer to Fig.24 , the control structure of the vacuum cleaner base station 100 of the present invention is explained.

[0349] The vacuum cleaner base station 100 according to the embodiment of the present invention may further include a control unit 400 that controls the combining portion 120 , the fixing unit 130 , the door unit 140 , the cover opening unit 150 , the dust collecting portion 170 , the flow path portion 180 , and the dust suction module 190 .

[0350] The control unit 400 may include a printed circuit board and components mounted on the printed circuit board.

[0351] When the combination sensor 125 senses the combination of the cleaner 200, the combination sensor 125 may send a signal that the cleaner 200 is combined with the combination part 120. At this time, the control part 400 may determine that the cleaner 200 is combined with the combination part 120 by receiving the signal of the combination sensor 125.

[0352] In addition, when power is supplied from the charging unit 128 to the battery 240 of the vacuum cleaner 200 , the control unit 400 may determine that the vacuum cleaner 200 has been coupled to the coupling unit 120 .

[0353] When it is determined that the vacuum cleaner 200 is coupled to the coupling portion 120 , the control portion 400 may operate the fixing portion motor 133 to fix the vacuum cleaner 200 .

[0354] When the fixing member 131 or the fixing part coupling member 135 moves to the prescribed fixing position FP1, the fixing sensor 137 may send a signal indicating that the cleaner 200 has been fixed. The control unit 400 may determine that the cleaner 200 has been fixed by receiving the signal indicating that the cleaner 200 has been fixed from the fixing sensor 137. When it is determined that the cleaner 200 has been fixed, the control unit 400 may interrupt the operation of the fixing motor 133.

[0355] On the other hand, when the dust container 220 is emptied, the control unit 400 may release the fixation of the cleaner 200 by rotating the fixing unit motor 133 in the reverse direction.

[0356] When it is determined that the cleaner 200 is fixed to the coupling portion 120 , the control unit 400 may open the door 141 of the cleaner base station 100 by operating the door motor 142 .

[0357] When the door 141 or the door arm 143 reaches the prescribed opening position DP1, the door opening and closing sensor 144 may send a signal that the door 141 has been opened. The control unit 400 may determine that the door 141 has been opened by receiving the signal that the door 141 has been opened from the door opening and closing sensor 144. When it is determined that the door 141 has been opened, the control unit 400 may interrupt the operation of the door motor 142.

[0358] On the other hand, when the dust container 220 is emptied, the control part 400 may close the door 141 by rotating the door motor 142 in the reverse direction.

[0359] When it is determined that the door 141 is opened, the control unit 400 may open the discharge cover 222 of the cleaner 200 by operating the cover opening motor 152 .

[0360] When the guide frame 351e reaches the prescribed opening position CP1, the cover opening sensor 155f may send a signal that the discharge cover 222 has been opened. The control unit 400 may determine that the discharge cover 222 has been opened by receiving the signal that the discharge cover 222 has been opened from the cover opening sensor 155f. When it is determined that the discharge cover 222 has been opened, the control unit 400 may interrupt the operation of the cover opening motor 152.

[0361] The control part 400 may engage the dust bag 172 by driving the engager 176. For example, the control part 400 may operate the first engaging member and move it in a first direction, and the control part 400 may operate the second engaging member and move it in a second direction perpendicular to the first direction.

[0362] On the other hand, in the present embodiment, the control unit 400 may operate the coupling 176 after the operation of the dust collecting motor 191 ends. As one example, the control unit 400 may operate the coupling 176 after a predetermined time has passed after the operation of the dust collecting motor 191 ends. As another example, the control unit 400 may operate the coupling 176 after a predetermined time has passed after the dust collecting motor 191 has operated a predetermined number of times. As yet another example, the control unit 400 may operate the coupling 176 in each predetermined cycle, and operate the coupling 176 after a predetermined time has passed when the dust collecting motor 191 is operating. In addition, the control unit 400 may also operate the coupling 176 when the amount of dust measured by the dust amount sensor (not shown) exceeds a predetermined reference.

[0363] With the above configuration, the dust bag 172 can be sealed in a state where the dust settles in the dust bag 172 instead of floating inside the cleaner base station 100 , thereby improving hygiene.

[0364] On the other hand, in this embodiment, the control unit 400 can determine whether the dust bag box 174 is installed through the box sensing sensor 176c. If the box sensing sensor 176c contacts the dust bag box 174, the box sensing sensor 176c can send the contact to the control unit 400. At this time, the control unit 400 can control the dust collection motor 191 to operate only when the dust bag box 174 is installed.

[0365] By the above configuration, the control unit 400 can make the dust collection of the dust barrel 220 only be performed when the dust bag 172 is set in the vacuum cleaner base station 100. Therefore, it is possible to prevent the vacuum cleaner base station 100 from malfunctioning due to foreign matter contaminating the interior of the vacuum cleaner base station 100 by collecting dust without the dust bag 172, thereby preventing the dust bag 172 from collecting dust and causing foreign matter to contaminate the interior of the vacuum cleaner base station 100.

[0366] The control unit 400 may drive the dust collecting motor 191 to suck in the dust inside the dust container 220 .

[0367] The control unit 400 can display the emptying status and charging status of the dust bucket of the vacuum cleaner 200 by operating the display unit 410. For example, in this embodiment, when the amount of dust measured by the dust amount sensor exceeds a specified reference value, the control unit 400 can display on the display unit 410 that the dust bag 172 needs to be replaced.

[0368] On the other hand, the vacuum cleaner base station 100 of the present invention may include a display unit 410 .

[0369] The display unit 410 may be configured not only on the cover body 110 but also on an additional display device, and may also be provided on a terminal including a mobile phone.

[0370] The display unit 410 may be configured to include at least one of a display panel capable of outputting text and / or graphics and a speaker capable of outputting voice signals and sounds. Through the information output by the display unit, the user can easily grasp the current process status, remaining time, etc.

[0371] On the other hand, the vacuum cleaner base station 100 according to the embodiment of the present invention may include a memory 430. The memory 430 may include various data used for driving and operating the vacuum cleaner base station 100.

[0372] On the other hand, the vacuum cleaner base station 100 of the embodiment of the present invention may include an input unit 440. The input unit 440 generates key input data input by the user for the operation control of the vacuum cleaner base station 100. To this end, the input unit 440 may be composed of a keyboard (keypad), a dome switch (dome switch), a touch panel (static pressure / static electricity), etc. In particular, when the touch panel and the display unit 410 form a layer structure with each other, it can be called a touch screen (touch screen).

[0373] The present invention has been described in detail above through specific embodiments, but the above description is only used to specifically illustrate the present invention and the present invention is not limited thereto. It is obvious that the present invention can be modified or improved by those skilled in the art within the scope of the technical idea of ​​the present invention.
