Vacuum cleaner and vacuum cleaner system

Abstract

The invention relates to a vacuum cleaner and a vacuum cleaner system. The vacuum cleaner comprises a dust barrel; a suction unit that guides air to the inside of the dust tub; a suction motor generating a suction force to suck air through the suction portion; a cyclone unit that separates dust from the air by causing the air sucked in by the suction unit to flow as a cyclone; and a filter unit for filtering the air discharged from the cyclone unit. The filtering part comprises a filter main body which is arranged in the dust barrel and forms the cyclone flow along the periphery of the outer side of the filter main body; and a filter hole for guiding air into the filter main body. The air flowing into the inside of the filter main body through the filter holes flows into the filter main body in a state of being inclined in a reverse direction with respect to the advancing direction of the cyclone flow formed at the inlet side of the filter holes, so that hair can be prevented from being stuck in the filter holes.

Description

Technical Field

[0001] The present invention relates to a vacuum cleaner and a vacuum cleaner system, and more particularly to a vacuum cleaner and a vacuum cleaner system capable of preventing hair from being stuck in mesh holes of a dust bucket. Background Art

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

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

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

[0005] In a cylinder 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. Although it is lightweight, it is short and requires squatting to clean, so the cleaning area is limited. Therefore, it is used to clean local places such as desks, sofas, or cars.

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

[0008] Figure 1 The present invention is a cross-sectional view showing a state in which a cyclonic flow is generated inside a dust bin of a conventional vacuum cleaner.

[0009] Reference Figure 1In the existing vacuum cleaner, the sucked air generates a cyclonic flow inside the first cyclone part 20 and flows into the second cyclone part 30 due to the suction force of the suction motor. During this process, the air flows in through the filter holes 41 of the filter part 40 surrounding the second cyclone part 30.

[0010] However, since the direction D10 in which air flows into the second cyclone portion 30 through the filter hole 41 and the direction D20 in which the cyclone flow travels at the inlet side of the filter hole 41 form a right angle, hair rotating outside the filter portion 40 along the cyclone flow frequently gets stuck in the filter hole 41 .

[0011] For this reason, the filter holes 41 are clogged with hair, so there is a problem that the suction force of the vacuum cleaner is reduced.

[0012] In addition, since the hair is stuck in the filter hole 41 and does not come out, there is a trouble that the user needs to separate the cleaner every time to remove the hair.

[0013] In addition, since hair is caught in the filter hole 41, there may be a problem of hygiene, and there is a problem of generating odor due to the residues caught in the hair.

[0014] As a conventional patent document, International Patent Publication No. 2012-113782 discloses a filter unit for a vacuum cleaner.

[0015] In the prior art patent document, in order to increase the contact area between the filter body and the air containing dust, pleats are formed along the length direction of the filter body.

[0016] However, in the above-mentioned prior art patent document, the pleats formed along the length direction of the filter body are used to improve the efficiency of the filter unit by increasing the contact area between the filter body and the air containing dust, and do not have the effect of preventing the suction force of the vacuum cleaner from being reduced by removing hair stuck in the filter unit. Summary of the invention

[0017] Problems to be solved by the invention

[0018] The present invention is proposed to improve the above-mentioned problem, and the problem lies in preventing hair from getting stuck in the filter holes.

[0019] In addition, there is a problem in preventing hair from getting caught in the filter holes, thereby preventing the suction power of the vacuum cleaner from being reduced.

[0020] In addition, there is a problem in eliminating the trouble of requiring the user to separate the vacuum cleaner every time to remove the hair.

[0021] Another problem is whether the inside of the dust bin can be kept clean and sanitary.

[0022] In addition, there is a problem in preventing the tangled residues on the hair inside the dust bin from corroding and generating odor.

[0026] An angle between a first direction, which is an inner direction of a central axis of the filter hole, and a second direction, which is a tangential direction of the cyclone flow intersecting the central axis, may be an obtuse angle.

[0027] The angle may be 110 to 150 degrees.

[0028] An inner surface of the filter hole may be formed to be tilted inversely with respect to a traveling direction of the cyclone flow formed at an inlet side of the filter hole.

[0029] A first intersection area where the inner surface of the filter hole and the outer side surface of the filter body intersect may be configured to be more biased toward the traveling direction of the cyclonic flow than a second intersection area where the inner surface of the filter hole and the inner side surface of the filter body intersect.

[0030] A first penetration line penetrating the first intersection line area in a direction perpendicular to the traveling direction of the cyclonic flow and a second penetration line penetrating the second intersection line area in a direction perpendicular to the traveling direction of the cyclonic flow may penetrate the filter body.

[0031] The filter body may be formed of at least one material selected from plastic and metal.

[0032] A plurality of the filter holes may be formed along the outer peripheral edge of the filter body in the length direction.

[0033] Central axes of at least a portion of the plurality of filter holes may be formed parallel to each other.

[0035] The cyclonic flow may include at least one turning point that converts a traveling direction from a direction flowing along an outside of the filter body to a direction flowing into an inside of the filter body through the filter holes.

[0036] The air passing through the filter hole may pass in a state of being reversely inclined with respect to a traveling direction of the cyclone flow formed at an inlet side of the filter hole.

[0037] In order to solve the problems mentioned above, the vacuum cleaner system of the present invention includes: a vacuum cleaner, including a dust bin and a suction part that guides air into the interior of the dust bin; and a vacuum cleaner base station, including a cover body, a dust collecting part, a flow path part and a dust collecting motor, the cover body is provided with a coupling part for the vacuum cleaner to be placed and coupled, the dust collecting part is accommodated in the interior of the cover body and captures dust inside the dust bin, the flow path part connects the dust through hole formed in the coupling part with the dust collecting part, and the dust collecting motor is arranged at the lower side of the dust collecting part and generates suction so that dust flows into the interior of the dust collecting part through the flow path part ; The vacuum cleaner includes: a cyclone part, which separates dust from the air sucked in by the suction part through a cyclone flow generated by the suction force of the dust collecting motor; and a filter part, which filters the air discharged from the cyclone part; the filter part includes: a filter body, which is arranged inside the dust bin and forms the cyclone flow along the outer peripheral edge of the filter body; and a filter hole, which guides the air into the interior of the filter body; the air flowing into the interior of the filter body through the filter hole can flow in at a state of being tilted in the opposite direction to the traveling direction of the cyclone flow formed on the inlet side of the filter hole.

[0038] An angle between a direction in which air flows into the interior of the filter body through the filter holes and a traveling direction of the cyclone flow formed at an inlet side of the filter holes may be an obtuse angle.

[0039] An angle between a first direction, which is an inner direction of a central axis of the filter hole, and a second direction, which is a tangential direction of the cyclone flow intersecting the central axis, may be an obtuse angle.

[0040] The angle may be 110 to 150 degrees.

[0041] Effects of the Invention

[0042] As described above, according to the vacuum cleaner and the vacuum cleaner system of the present invention, it is possible to prevent hair rotating outside the filter portion along the cyclonic flow from getting caught in the filter holes.

[0043] In addition, it can prevent hair stuck in the filter holes from reducing the suction power of the vacuum cleaner.

[0044] In addition, even if hair is stuck in the filter hole, it can be prevented from being stuck in a deeper position, so that when the vacuum cleaner is coupled to the vacuum cleaner base station, the hair stuck in the filter hole can be removed by the suction force of the vacuum cleaner base station.

[0045] In addition, when the suction motor of the vacuum cleaner or the dust collecting motor of the vacuum cleaner base station is operated, the hair stuck in the filter hole can be easily removed.

[0046] In addition, by preventing hair from getting caught in the filter holes, the inside of the dust bin can be kept clean and sanitary.

[0047] In addition, since hair is prevented from remaining inside the dust box, it is possible to prevent the residue tangled in the hair from corroding and generating odor. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] Figure 2 A three-dimensional diagram of a vacuum cleaner system consisting of a vacuum cleaner base station and a vacuum cleaner according to an embodiment of the present invention is disclosed. Figures 3 to 5 A schematic diagram of the configuration of a vacuum cleaner system according to various embodiments of the present invention is disclosed.

[0074] Reference Figure 2 and Figure 3 , a vacuum cleaner system 10 according to an embodiment of the present invention may include a vacuum cleaner base station 100 and a vacuum cleaner 200 .

[0075] The vacuum cleaner system 10 may include a vacuum cleaner base station 100. A vacuum cleaner 200 may be combined with the vacuum cleaner base station 100. Specifically, a 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.

[0076] on the other hand, Figure 4 and Figure 5 Disclosed are diagrams for explaining a vacuum cleaner in a vacuum cleaner system according to an embodiment of the present invention. Figure 6 A diagram of the lower side of a dust bucket of a vacuum cleaner for illustrating an embodiment of the present invention is disclosed. Figure 7 A side view of a vacuum cleaner according to an embodiment of the present invention is disclosed. Figure 8 Publicly published along Figure 7 The cross-sectional view taken along the A-A' line in the figure is: Fig. 9 Publicly published along Figure 8 The cross-sectional view taken along the line B-B' in the figure is: Fig.10 An exploded view of a vacuum cleaner according to an embodiment of the present invention is disclosed.

[0077] Reference Figures 4 to 10, the structure of the vacuum cleaner 200 is described as follows.

[0078] 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.

[0079] 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.

[0080] On the other hand, in one embodiment of the present invention, the direction of the vacuum cleaner 200 may be defined based on the condition that the dust bin 220 and the bottom surface (lower side) of the battery cover 230 are placed on the ground.

[0081] 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 based on the situation of observing the suction unit 212 from the suction motor 214 may be referred to as the right side, and the direction configured on the left 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 in a direction perpendicular to the ground based on the situation of placing the bottom surface (lower side) of the dust bin 220 and the battery cover 230 on the ground.

[0082] The vacuum cleaner 200 may include a body 210 . The body 210 may include a body cover 211 , a suction part 212 , a cyclone part 213 , a suction motor 214 , an air discharge cover 215 , a handle 216 , and an operation part 218 .

[0083] 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 a suction motor 214 and a filter (not shown) inside. The main body cover 211 may be configured in a shape similar to a cylinder.

[0084] 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 inner opening. The suction part 212 may be combined with the extension pipe 250. The suction part 212 may provide a suction flow path 212a through which air containing dust may flow.

[0085] On the other hand, in this embodiment, a virtual line may be formed to pass through the inside of the cylindrical suction part 212. In this case, the virtual line may be referred to as the longitudinal axis a1 of the suction flow path.

[0086] The cyclone part 213 may communicate with the suction part 212. The cyclone part 213 may separate dust sucked into the inside through the suction part 212. The space inside the cyclone part 213 may communicate with the space inside the dust container 220.

[0087] The cyclone part 213 may have at least one cyclone part capable of separating dust by cyclonic flow. The cyclone part 213 is connected to the suction part 212, and in order to separate the dust sucked into the inside of the body 210 through the suction part 212, a dust collector principle using centrifugal force is applied. That is, the cyclone part 213 may refer to a part of the space inside the dust barrel 220.

[0088] As an example, the cyclonic flow generated in the cyclone portion 213 may be generated by the suction force generated by the suction motor 214 .

[0089] As another example, the cyclone flow generated in the cyclone portion 213 may be generated by the suction force generated in the dust collecting motor 191 .

[0090] That is, the cyclone flow generated in the cyclone part 213 can be generated by the suction force of the suction motor 214 when the vacuum cleaner 200 is used alone or by the suction force of the dust collection motor 191 when the vacuum cleaner 200 is combined with the vacuum cleaner base station 100.

[0091] On the other hand, the cyclone flow may be formed between the inner side of the dust container 220 and the outer side of the filter body 310. The cyclone flow may be formed between the inner circumferential surface of the cyclone portion 213 and the outer circumferential surface of the filter body 310.

[0092] The space inside the cyclone part 213 may be communicated with the suction part 212. The air and dust sucked through the suction part 212 may flow along the inner circumference of the cyclone part 213, thereby generating a cyclone flow in the inner space of the cyclone part 213.

[0093] As an example, the cyclone flow generated in the cyclone portion 213 may be formed to surround in a circular shape along the outer peripheral edge of the filter body 310. That is, the air sucked in through the suction portion 212 flows in a circular shape along the outer peripheral surface of the filter body 310 with the central axis a5 of the filter body 310 as a reference, thereby generating a cyclone flow in the internal space of the cyclone portion 213.

[0094] Specifically, when the axis a4 of the cyclonic flow is arranged perpendicularly to the lower side of the gravity direction, the air sucked through the suction part 212 can flow in a circular shape along the outer peripheral surface of the filter body 310 with the central axis a5 of the filter body 310 as the reference. Alternatively, when the axis a4 of the cyclonic flow is arranged parallel to the ground, the air sucked through the suction part 212 can flow in a circular shape along the outer peripheral surface of the filter body 310 with the central axis a5 of the filter body 310 as the reference.

[0095] As another example, the cyclone flow generated in the cyclone portion 213 may be formed in a spiral shape along the outer periphery of the filter body 310. That is, the air sucked in through the suction portion 212 may flow in a spiral along the outer periphery of the filter body 310, thereby generating a cyclone flow in the inner space of the cyclone portion 213. Therefore, a cyclone flow may be generated in the inner space of the cyclone portion 213.

[0096] Specifically, when the axis a4 of the cyclonic flow is tilted relative to the ground, the air sucked through the suction part 212 can flow in a spiral shape along the outer periphery of the filter body 310. Alternatively, when the vacuum cleaner 200 is combined with the vacuum cleaner base station 100 and the dust through hole 121a is open, the air sucked through the suction part 212 can flow in a spiral shape along the outer periphery of the filter body 310 by the suction force of the dust collecting motor 191.

[0097] On the other hand, the vacuum cleaner 200 may include a cyclone module 270 that separates dust again from the air discharged from the cyclone unit 213. At this time, the cyclone module 270 may be arranged inside the cyclone unit 213 to minimize the size of the vacuum cleaner 200. Specifically, the cyclone module 270 may be arranged inside the filter unit 300. That is, the cyclone unit 213 and the cyclone module 270 may be arranged inside the dust barrel 220 via the filter unit 300.

[0098] The cyclone module 270 may include a plurality of cyclone bodies 271 arranged in parallel. Therefore, the air exhausted from the cyclone portion 213 may be separated and passed through the plurality of cyclone bodies 271 via the filter portion 300 .

[0099] As another example, the cyclone module 270 may include a single cyclone body 271. In this case, the axis of the cyclone flow of the cyclone module 270 may extend in the up-down direction.

[0100] In addition, the axis of the cyclone flow of the cyclone module 270 can also extend in the up-down direction, and the axis of the cyclone flow of the cyclone section 213 and the axis of the cyclone flow of the cyclone module 270 can form a coaxial axis in the up-down direction, which can be collectively referred to as the axis a4 of the cyclone flow of the cyclone section 213.

[0101] A storage unit 280 storing dust separated from the cyclone module 270 may be disposed inside the dust barrel 220. The storage unit 280 may be coupled to the lower side of the cyclone module 270 and contact the top surface of the discharge cover 222. The lower side of the storage unit 280 may be opened.

[0102] The storage unit 280 may partition the space inside the dust barrel 220 into a first dust storage part 220 a storing dust separated from the cyclone part 213 and a second dust storage part 280 a storing dust separated from the cyclone module 270 .

[0103] Therefore, the lower inner space of the storage unit 280 may be defined as a second dust storage portion 280a, and the space between the storage unit 280 and the dust barrel 220 may be defined as a third dust storage portion 220a.

[0104] The discharge cover 222 can open and close the first dust storage part 220a and the second dust storage part 280a together. That is, the first dust storage part 220a and the second dust storage part 280a can be exposed to the outside together.

[0105] The suction motor 214 can generate suction force for sucking air. The suction motor 214 can be accommodated in the main body cover 211. The suction motor 214 can generate suction force by rotating. As an example, the suction motor 214 can have a shape similar to a cylinder.

[0106] At this time, a cyclonic flow may be generated by the suction force of the suction motor 214 .

[0107] Specifically, when the suction motor 214 is operated, the air sucked in by the suction force of the suction motor 214 through the suction part 212 can generate a cyclonic flow in the cyclone part 213 .

[0108] On the other hand, in the present embodiment, a virtual rotation axis a2 of the suction motor may be formed by extending the rotation axis of the suction motor 214 .

[0109] The suction portion 212 may be combined with the body 210 such that a central portion is substantially located at a boundary between the dust container 220 and the body cover 211 .

[0110] The suction motor 214 may be located inside the main body cover 211 . Also, at least a portion of the suction motor 214 may be located on the upper side of the cyclone portion 213 . Therefore, the suction motor 214 may be located above the dust container 220 .

[0111] The suction motor 214 may be in communication with the exhaust port of the cyclone module 270 .

[0112] To this end, a discharge guide 291 b connected to the cyclone module 270 and a flow guide 291 a communicating with the discharge guide 291 b may be provided inside the main body cover 211 .

[0113] As an example, the discharge guide 291 b is located on the upper side of the cyclone module 270 , and the flow guide 291 a is located on the upper side of the discharge guide 291 b .

[0114] Also, at least a portion of the suction motor 214 is located inside the flow guide 291 a.

[0115] Therefore, the axis a4 of the cyclone flow of the cyclone portion 213 may penetrate the suction motor 214 .

[0116] In an embodiment of the present invention, if the suction motor 214 is located at the upper side of the cyclone module 270 , the air exhausted from the cyclone module 270 may flow directly toward the suction motor 214 , thereby minimizing the flow path between the cyclone part 213 and the suction motor 214 .

[0117] The suction motor 214 may include an impeller 214a that rotates. The impeller 214a may be connected to a shaft 214b. The shaft 214b is configured to extend in the up-down direction.

[0118] In addition, the impeller 214a may be disposed on the upper side of the suction motor 214. In this case, the air may flow downward from the upper side of the suction motor 214 by the impeller 214a.

[0119] The rotation axis of the impeller 214a and the axis a4 of the cyclonic flow generated in the cyclone portion 213 may be located on the same line.

[0120] According to the embodiment of the present invention, there are the following advantages: the air discharged from the cyclone part 213, that is, the air discharged upward from the cyclone module 270 has a shorter flow path toward the suction motor 214 side, the direction change of the air is reduced, and thus the flow loss of the air is reduced.

[0121] When the flow loss of air is reduced, the suction force can be increased and the suction efficiency can be improved. In addition, the usage time of the battery 9 for supplying power to the suction motor 214 can be increased.

[0122] The vacuum cleaner 200 may further include a motor housing 292 supporting the suction motor 214 .

[0123] The motor covers 292a and 292b may be composed of an upper motor cover 292a covering a portion of the upper side of the suction motor 214 and a lower motor cover 292b covering a portion of the lower side of the suction motor 214. The suction motor 214 may be configured to be accommodated inside each motor cover 292a and 292b, and the flow guide 291a surrounds the motor covers 292a and 292b.

[0124] At least a portion of the flow guide 291a may be separated from the motor housings 292a and 292b. In addition, at least a portion of the flow guide 291a may be separated from the body housing 211.

[0125] Therefore, the inner circumference of the flow guide 291a and the outer circumference of the upper motor cover 292a may form a first air flow path 211a, and the outer circumference of the flow guide 291a and the inner circumference of the body cover 211 may form a second air flow path 211b.

[0126] According to the embodiment of the present invention, a single flow guide 291a forms a plurality of air flow paths, ie, the first air flow path 211a and the second air flow path 211b, and the number of components for forming each air flow path can be reduced, thereby having an advantage of a simple structure.

[0127] The air discharged from the cyclone module 270 may flow along the first air flow path 211a toward the suction motor 214, and the air discharged from the suction motor 214 may flow along the second air flow path 211b and then be discharged to the outside. Therefore, the first air flow path 211a functions as a suction flow path, and the second air flow path 211b functions as an exhaust flow path.

[0128] The air outlet cover 215 may be disposed on one axial side of the main body cover 211. A filter for filtering air may be accommodated in the air outlet cover 215. As an example, a high efficiency air (HEPA) filter may be accommodated in the air outlet cover 215.

[0129] An air outlet for discharging air sucked by the suction force of the suction motor 214 may be formed at the air outlet cover 215. The flow guide 291a and the discharge guide 291b may guide the flow of air discharged through the air outlet.

[0130] The handle 216 can be held by the user. The handle 216 can be arranged behind the suction motor 214. As an example, the handle 216 can be formed in a shape similar to a cylinder. Alternatively, the handle 216 can be formed in a curved cylindrical shape. The handle 216 can form a specified angle with the main body cover 211, the suction motor 214, or the cyclone part 213.

[0131] The handle 216 may include: a gripping portion formed in a columnar shape so that the user can grip it; a first extension portion connected to one end portion of the gripping portion in the length direction (axial direction) and extending toward the suction motor 214; and a second extension portion connected to the other end portion of the gripping portion in the length direction (axial direction) and extending toward the dust bin 220.

[0132] On the other hand, in this embodiment, a virtual grip portion penetration line a3 extending along the length direction of the grip portion (the axial direction of the column) and penetrating the grip portion may be formed.

[0133] As an example, the grip portion penetration line a3 may be a virtual line formed inside the cylindrical handle 216, or may be a virtual line formed parallel to at least a portion of the outer side surface (outer peripheral surface) of the grip portion.

[0134] 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.

[0135] The first extension portion may extend from the grip portion toward the body cover 211 or the suction motor 214. At least a portion of the first extension portion may extend in a horizontal direction.

[0136] The second extension portion may extend from the grip portion toward the dust bin 220. At least a portion of the second extension portion may extend in a horizontal direction.

[0137] 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.

[0138] The cleaner 200 may include a dust container 220. The dust container 220 may be in communication with the cyclone portion 213. The dust container 220 may store dust separated from the cyclone portion 213.

[0139] 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).

[0140] The dust container body 221 may provide a space capable of storing dust separated from the cyclone portion 213. As an example, the dust container body 221 may be formed in a shape similar to a cylinder.

[0141] On the other hand, in this embodiment, a virtual 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).

[0142] A portion of the lower side (bottom) of the dust bin body 221 may be open. In addition, a bottom surface extension portion 221a may be formed on the lower side (bottom) of the dust bin body 221. The bottom surface extension portion 221a may be formed to block a portion of the lower side of the dust bin body 221.

[0143] The dust container 220 may include a discharge cover 222. The discharge cover 222 may be disposed on a lower side of the dust container 220.

[0144] 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 opens downward.

[0145] The discharge cover 222 may include a cover body 222a and a hinge portion 222b. The cover body 222a may be formed to block a portion of the lower side of the dust bin body 221. The cover body 222a may rotate downward with the hinge portion 222b as a reference. The hinge portion 222b may be arranged adjacent to the battery cover 230. A torsion spring 222d may be provided at the hinge portion 222b. Therefore, when the discharge cover 222 is separated from the dust bin body 221, due to the elastic force of the torsion spring 222d, the cover body 222a may be supported in a state of rotating more than a specified angle with the hinge portion 222b as an axis in the dust bin body 221.

[0146] 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 a 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.

[0147] When the discharge cover 222 is in a closed state, the lower side of the dust container 220 may be blocked (sealed) by the discharge cover 222 and the bottom surface extension 221 a .

[0148] The dust container 220 may include a dust container compression rod 223 (see Figure 4 ). The dust bin compression rod 223 can be arranged outside the dust bin 220 or the cyclone part 213. The dust bin compression rod 223 can be arranged outside the dust bin 220 or the cyclone part 213 so as to be movable up and down. The dust bin compression rod 223 can be connected to a compression member (not shown). In the case where the dust bin compression rod 223 is moved downward by an external force, the compression member (not shown) can also move downward together. Thus, user convenience can be provided. The compression member (not shown) and the dust bin compression rod 223 can be reset to the original position by an elastic member (not shown). Specifically, in the case where the external force applied to the dust bin compression rod 223 is released, the elastic member can cause the dust bin compression rod 223 and the compression member (not shown) to move upward.

[0149] A compression member (not shown) may be disposed inside the dust bin body 221. The compression member may move in the internal space of the dust bin body 221. Specifically, the compression member may move up and down inside the dust bin body 221. Thus, the compression member may compress the dust inside the dust bin body 221 downward. In addition, when the discharge cover 222 is separated from the dust bin body 221 and the lower portion of the dust bin 220 is open, the compression member moves from the upper portion to the lower portion of the dust bin 220, thereby being able to remove foreign matter such as residual dust inside the dust bin 220. Thus, the suction force of the vacuum cleaner may be increased by preventing the residual dust from remaining inside the dust bin 220. Furthermore, by preventing the residual dust from remaining inside the dust bin 220, the odor generated by the residual matter may be removed.

[0150] 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.

[0151] 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 .

[0152] The vacuum cleaner 200 may include a battery 240 .

[0153] For example, the battery 240 may be detachably coupled to the vacuum cleaner 200. The battery 240 may be detachably coupled to the battery cover 230. As an example, the battery 240 may be inserted into the battery cover 230 from below. With this configuration, the portability of the vacuum cleaner 200 may be improved.

[0154] Alternatively, the battery 240 may be provided integrally with the battery cover 230 inside the battery cover 230. In this case, the bottom surface of the battery 240 is not exposed to the outside.

[0155] The battery 240 may supply power to the suction motor 214 of the cleaner 200. The battery 240 may be disposed at the lower portion of the handle 216. The battery 240 may be disposed at the rear of the dust container 220.

[0156] 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 a floor surface, the battery 240 may be placed on the floor, so the battery 240 may be directly separated from the battery cover 230. In addition, the bottom surface of the battery 240 is exposed to the outside and directly contacts the outside air of the battery 240, so the cooling performance of the battery 240 may be improved.

[0157] On the other hand, when the battery 240 and the battery cover 230 are fixed integrally, the structure for attaching and detaching the battery 240 and the battery cover 230 can be reduced, so the overall size of the vacuum cleaner 200 can be reduced and the weight can be reduced.

[0158] 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 body 210. The extension pipe 250 may be in communication with the suction part 212 of the body 210. The extension pipe 250 may be formed in a long cylindrical shape.

[0159] The body 210 may be connected to the extension tube 250. The body 210 may be connected to the cleaning module 260 through the extension tube 250. The body 210 generates suction through the suction motor 214, and may provide suction to the cleaning module 260 through the extension tube 250. External dust may flow into the body 210 through the cleaning module 260 and the extension tube 250.

[0160] The cleaner 200 may include a cleaning module 260. The cleaning module 260 may be in communication with the extension tube 250. Therefore, external air may flow into the body 210 of the cleaner 200 through the cleaning module 260 and the extension tube 250 under the effect of the suction force generated by the body 210 of the cleaner 200.

[0161] The dust in the dust bucket 220 of the vacuum cleaner 200 can be captured by gravity and the suction force of the dust collecting motor 191 to the dust collecting unit 170 of the vacuum cleaner base station 100. Thus, the dust in the dust bucket can be removed without the user's separate operation, thereby improving user convenience. In addition, the trouble of the user emptying the dust bucket every time can be eliminated. In addition, the scattering of dust when the dust bucket is emptied can be prevented.

[0162] The vacuum cleaner 200 may be combined with the side of the cover body 110. Specifically, the body 210 of the vacuum cleaner 200 may be placed on the joint part 120. More specifically, the dust bucket 220 and the battery cover body 230 of the vacuum cleaner 200 may be combined with the joint surface 121, the outer peripheral surface of the dust bucket body 221 may be combined with the dust bucket guide surface 122, and the suction part 212 may be combined with the suction part guide surface 126 of the joint part 120. In this case, the central axis of the dust bucket 220 may be arranged in a direction parallel to the ground, and the extension tube 250 may be arranged in a direction perpendicular to the ground.

[0163] Reference Figure 2 and Figure 3 , the vacuum cleaner base station 100 of the present invention is described as follows.

[0164] The vacuum cleaner base station 100 may be configured with a vacuum cleaner 200. The vacuum cleaner 200 may be combined with the side of the vacuum cleaner base station 100. Specifically, the body of 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 the dust barrel 220 of the vacuum cleaner 200.

[0165] 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.

[0166] The cover body 110 may be formed with a space in which the dust collecting part 170 storing dust therein and the dust suction module 190 generating a flow force to collect dust toward the dust collecting part 170 can be accommodated.

[0167] The cover body 110 may include a bottom surface 111 , an outer wall surface 112 , and an upper surface 113 .

[0168] 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 171 of the dust suction module 190.

[0169] At this time, the bottom surface 111 can be arranged toward the ground. The bottom surface 111 can be arranged parallel to the ground, or can be arranged to be inclined at a predetermined angle to the ground. This structure has the advantage of being able to stably support the dust collecting motor 171, and when combined with the vacuum cleaner 200, the overall weight can also be balanced.

[0170] On the other hand, according to an embodiment, the bottom surface 111 may further include a bottom surface support portion 111a, which increases the area in contact with the ground to prevent the vacuum cleaner base station 100 from tipping over and maintain balance. As an example, the bottom surface support portion may be in the shape 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 in the direction of the ground.

[0171] 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.

[0172] 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.

[0173] 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 surface of the vacuum cleaner 200 exposed when the vacuum cleaner 200 is combined with the vacuum cleaner base station 100. Therefore, the first outer wall surface 112a can form the appearance of the front side of the vacuum cleaner base station 100.

[0174] On the other hand, in order to understand the present embodiment, the direction is defined as follows: In the present embodiment, the direction may be defined in a state where the cleaner 200 is placed on the cleaner base station 100 .

[0175] 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.

[0176] From another perspective, the direction in which the suction motor 214 of the vacuum cleaner 200 is arranged when the vacuum cleaner 200 is placed on the vacuum cleaner base station 100 can be called the front. In addition, the opposite direction of the direction in which the suction motor 214 in the vacuum cleaner base station 100 is arranged can be called the rear.

[0177] Furthermore, the surface in the direction opposite to the front side with respect to the internal space of the housing 110 as a reference may be referred to as the back side of the vacuum cleaner base station 100. Therefore, the back side may refer to the direction formed by the second outer wall surface 112b.

[0178] Furthermore, the left side when observing the front side with the internal space of the cover body 110 as a reference may be referred to as the left side, and the right side may be referred to as the right side. Therefore, the left side may refer to the direction formed by the third outer wall surface 112c, and the right side may refer to the direction formed by the fourth outer wall surface 112d.

[0179] The first outer wall surface 112a may be formed in a planar shape, or may be formed in a curved shape as a whole, or may be formed with a curved surface in part.

[0180] The first outer wall surface 112a may have an appearance corresponding to the shape of the vacuum cleaner 200. In detail, 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 may be supported by the vacuum cleaner base station 100. The specific configuration of the coupling portion 120 will be described later.

[0181] 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 112 a .

[0182] 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. Here, the back side may refer to a surface facing the surface with which the vacuum cleaner 200 is combined. Therefore, the second outer wall surface 112b may form the appearance of the back side of the vacuum cleaner base station 100.

[0183] As an example, the second outer wall surface 112b may be formed in a flat surface. According to such a configuration, the vacuum cleaner base station 100 can be brought into close contact with the indoor wall, and the vacuum cleaner base station 100 can be stably supported.

[0184] As another example, a structure for placing various types of cleaning modules 260 used in the cleaner 200 may be added to the second outer wall surface 112 b.

[0185] 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 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.

[0186] The third outer wall surface 112c or the fourth outer wall surface 112d is formed in a flat shape, but of course, it can be formed in a curved shape as a whole, and can be formed to include a curved surface in a part.

[0187] On the other hand, a structure for placing various types 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.

[0188] 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 of the vacuum cleaner base station that is disposed at the uppermost side in the gravity direction and exposed to the outside.

[0189] 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.

[0190] At this time, the upper surface 113 may be arranged parallel to the ground, or may be arranged to be inclined at a predetermined angle to the ground.

[0191] The display unit 410 may be disposed on the upper surface 113. As an example, the display unit 410 may display the status of the vacuum cleaner base station 100 and the status of the vacuum cleaner 200, and may also display information such as the cleaning progress status and a map of the cleaning area.

[0192] On the other hand, according to an embodiment, the upper surface 113 may be detachably provided from the outer wall surface 112. At this time, if the upper surface 113 is separated, the battery separated from the vacuum cleaner 200 may be accommodated in the inner space surrounded by the outer wall surface 112, and a terminal (not shown) capable of charging the separated battery may be provided.

[0193] Fig.11 A diagram for illustrating a joint portion in a vacuum cleaner base station according to an embodiment of the present invention is disclosed. Fig.12 An exploded perspective view of a fixing unit in a vacuum cleaner base station for illustrating an embodiment of the present invention is disclosed. Fig.13 and Fig.14 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 disclosed. Fig.15 Disclosed are diagrams for explaining a relationship between a vacuum cleaner and a lid opening unit in a vacuum cleaner base station according to an embodiment of the present invention.

[0194] Reference Figure 3 and Fig.11 , the coupling part 120 of the vacuum cleaner base station 100 of the present invention is described as follows.

[0195] The vacuum cleaner base station 100 may include a coupling portion 120 for coupling with the vacuum cleaner 200. Specifically, the coupling portion 120 may be disposed on the first outer wall surface 112a, and may be coupled with the body 210, the dust bin 220 and the battery cover 230 of the vacuum cleaner 200.

[0196] 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 groove-shaped surface that is recessed from the first outer wall surface 112a toward the inner side of the vacuum cleaner base station 100. That is, the coupling surface 121 may refer to a surface that forms a step with the first outer wall surface 112a.

[0197] The vacuum cleaner 200 can be combined on the combination surface 121. As an example, the combination surface 121 can contact the lower side of the dust bucket 220 and the battery cover 230 of the vacuum cleaner 200. Here, the lower side can refer to the side facing the ground when the user uses the vacuum cleaner 200 or places the vacuum cleaner 200 on the ground.

[0198] As an example, the angle formed by the coupling surface 121 and the ground may be a right angle. Thus, when the vacuum cleaner 200 is coupled to the coupling surface 121, the space of the vacuum cleaner base station 100 can be minimized.

[0199] As another example, the coupling surface 121 may be inclined at a predetermined angle to the ground. Thus, when the vacuum cleaner 200 is coupled to the coupling surface 121 , the vacuum cleaner base station 100 may be stably supported.

[0200] The joint surface 121 may be formed with a dust hole 121a to allow air outside the housing 110 to 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 portion 170. The dust hole 121a may be formed in a shape corresponding to the discharge cover 222 of the dust barrel 220. The dust hole 121a may be formed to communicate with the first suction flow path 181 described later.

[0201] 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.

[0202] The dust bucket guide surface 122 may be formed in a shape corresponding to the outer side surface of the dust bucket 220. The dust bucket guide surface 122 may be coupled to the front outer side surface of the dust bucket 220. Thus, the convenience of coupling the vacuum cleaner 200 to the coupling surface 121 may be provided.

[0203] On the other hand, a protrusion moving hole 122a may be formed on the dust bin guide surface 122, and the push protrusion 151 described later may move linearly along the protrusion moving hole 122a. In addition, a gear box 155 for accommodating gears and the like of the cover opening unit 350 described later may be provided on the lower side of the dust bin guide surface 122 in the gravity direction. At this time, a guide space 122b that enables the push protrusion 151 to move may be formed between the lower side surface of the dust bin guide surface 122 and the upper side surface of the gear box 155. Furthermore, the guide space 122b may be connected to the first suction flow path 181 via the bypass hole 122c. That is, the protrusion moving hole 122a, the guide space 122b, the bypass hole 122c and the first suction flow path 181 may form a bypass flow path (refer to Fig.10 With this configuration, if the dust collecting motor 191 is operated while the dust container 220 is 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 bypass flow path.

[0204] The coupling portion 120 may include a guide protrusion 123. The guide protrusion 123 may be configured on the coupling surface 121. The guide protrusion 123 may protrude upward from the coupling surface 121. Two guide protrusions 123 may be configured to be spaced apart from each other. The distance between the two spaced-apart guide protrusions 123 may correspond to the width of the battery cover 230 of the vacuum cleaner 200. Thus, the convenience of coupling the vacuum cleaner 200 to the coupling surface 121 can be provided.

[0205] The coupling portion 120 may include a side wall 124. The side wall 124 may refer to a wall surface disposed on both sides of the coupling surface 121, and may be vertically connected to the coupling surface 121. The side wall 124 may be connected to the first outer wall surface 112a. In addition, the side wall 124 may form a surface connected to the dust bin guide surface 122. Thus, the vacuum cleaner 200 may be stably accommodated.

[0206] 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.

[0207] 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, if the battery cover 230 or the battery 240 of the vacuum cleaner 200 is combined between a pair of guide protrusions 123, it will contact the combination sensor 125, and the combination sensor 125 can sense that the vacuum cleaner 200 has been combined.

[0208] 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 disposed on the side wall 124. Therefore, if the dust bin 220 or the body 210 of the vacuum cleaner 200 reaches the combined surface 121 via the side wall 124, the combined sensor 125 may sense the existence of the dust bin 220 or the body 210.

[0209] The combined sensor 125 may be opposite to the dust container 220 or the battery cover 230 of the cleaner 200 .

[0210] The coupling sensor 125 may be a device for determining whether the vacuum cleaner 200 is coupled while power is applied to the battery 240 of the vacuum cleaner 200 .

[0211] 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 be formed in a shape corresponding to the shape of the suction part 212.

[0212] 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 form along the side wall 124 to allow the fixing member 131 to enter and exit.

[0213] With this configuration, when the user couples the vacuum cleaner 200 to the coupling portion 120 of the vacuum cleaner base station 100, the body 210 of the vacuum cleaner 200 can be stably arranged on the coupling portion 120 due to the dust bucket guide surface 122, the guide protrusion 123, and the suction portion guide surface 126. Thus, the convenience of coupling the dust bucket 220 and the battery cover 230 of the vacuum cleaner 200 to the coupling surface 121 can be provided.

[0214] Reference Figure 3 , Fig.12 as well as Fig.16 , the fixing unit 130 of the present invention is described as follows.

[0215] 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. In addition, at least a portion of 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.

[0216] The fixing unit 130 may include a fixing member 131 for fixing the dust bucket 220 and the battery cover 230 of the vacuum cleaner 200, and a fixing motor 133 for driving the fixing member 131. In addition, the fixing unit 130 may further include a fixing connecting rod 135 for transmitting the power of the fixing motor 133 to the fixing member 131.

[0217] The fixing member 131 may be disposed on the side wall 124 of the coupling portion 120 , and may be reciprocatably disposed on the side wall 124 to fix the dust barrel 220 . Specifically, the fixing member 131 may be accommodated inside the fixing member access hole 127 .

[0218] The fixing members 131 may be respectively disposed on both sides of the coupling portion 120. As an example, two fixing members 131 may be symmetrically disposed in pairs with the coupling surface 121 as the center.

[0219] The fixing part motor 133 may provide power to move the fixing member 131 .

[0220] The fixing part link 135 may convert the rotation force of the fixing part motor 133 into the reciprocating movement of the fixing member 131 .

[0221] The fixed seal 136 may be disposed on the dust bucket guide surface 122 to airtightly seal the dust bucket 220 when the dust bucket 220 is combined with the vacuum cleaner 200. With this configuration, when the dust bucket 220 of the vacuum cleaner 200 is combined, the fixed seal 136 may be pressed by the weight of the vacuum cleaner 200, and the dust bucket 220 and the dust bucket guide surface 122 may be sealed.

[0222] The fixed seal 136 may be disposed on a virtual extension line of the fixed member 131. With this configuration, when the fixed portion motor 133 is operated and the fixed member 131 presses the dust container 220, the outer circumference of the dust container 220 at the same height may be sealed.

[0223] According to an embodiment, the fixed seal 136 may be disposed on the dust container guide surface 122 in a line form bent to correspond to the configuration of the cover opening unit 150 described later.

[0224] Therefore, when the body 210 of the vacuum cleaner 200 is disposed on the coupling part 120, the fixing unit 130 can fix the body 210 of the vacuum cleaner 200. Specifically, when the coupling sensor 125 senses that the 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 body 210 of the vacuum cleaner 200 by moving the fixing member 131.

[0225] Thus, the suction force of the vacuum cleaner can be improved by preventing the remaining dust from remaining in the dust barrel. Further, by preventing the remaining dust from remaining in the dust barrel, the odor generated by the residue can be removed.

[0226] Reference Figure 3 , Fig.13 , Fig.14 as well as Fig.16 , the door unit 140 of the present invention is described as follows.

[0227] The vacuum cleaner base station 100 of the present invention may include a door unit 140. The door unit 140 may be configured to be able to open and close the dust through hole 121a.

[0228] The door unit 140 may include a door 141 , a door motor 142 , and a door arm 143 .

[0229] The door 141 may be hingedly coupled to the coupling surface 121 and may open and close the dust through hole 121a. The door 141 may include a door body 141a.

[0230] The door body 141a may be formed in a shape capable of blocking the dust through hole 121a. As an example, the door body 141a may be formed in a shape similar to a circular plate.

[0231] Based on the state in which the door body 141a blocks the dust through hole 121a, a hinge portion may be disposed on the upper side of the door body 141a, and an arm joint portion 141b may be disposed on the lower side of the door body 141a.

[0232] The door body 141a may be formed into a shape capable of making the dust hole 121a airtight. As an example, the outer side surface of the door body 141a exposed to the outside of the vacuum cleaner base station 100 is formed to have a diameter corresponding to the diameter of the dust hole 121a, and the inner side surface disposed inside the vacuum cleaner base station 100 is formed to have a diameter larger than the diameter of the dust hole 121a. In addition, a step may be generated between the outer side surface and the inner side surface. On the other hand, at least one reinforcing rib may be protrudingly formed on the inner side surface of the door body 141a, and the reinforcing rib connects the hinge portion and the arm joint 141b to strengthen the support force of the door body 141a.

[0233] The hinge part may be a member that hinges the door 141 to the coupling surface 121. The hinge part may be disposed at an upper end portion of the door body 141a and coupled to the coupling surface 121.

[0234] The arm coupling part 141b may be a member to which the door arm 143 is rotatably coupled. The arm coupling part 141b may be disposed at the lower side of the door body 141a, rotatably coupled to the door body 141a, and rotatably coupled to the door arm 143.

[0235] With this configuration, when the door 141 closes the dust hole 121a, if the door arm 143 pulls the door body 141a, the door body 141a rotates toward the inside of the vacuum cleaner base station 100 with the hinge as the axis, and the dust hole 121a can be opened. On the other hand, when the dust hole 121a is open, if the door arm 143 pushes the door body 141a, the door body 141a rotates toward the outside of the vacuum cleaner base station 100 with the hinge 141b as the axis, and the dust hole 121a can be blocked.

[0236] On the other hand, when the cleaner 200 is combined with the cleaner base station 100 and the discharge cover 222 is separated from the dust container body 210, the door 141 may contact the discharge cover 222. And, as the door 141 rotates, the discharge cover 222 may rotate in conjunction with the door 141.

[0237] The door motor 142 may provide power to rotate the door 141. Specifically, the door motor 142 may cause the door arm 143 to rotate in a forward direction or a reverse direction. Here, the forward direction may refer to the direction in which the door arm 143 pulls the door 141. Therefore, if the door arm 143 rotates in the forward direction, the dust hole 121a may be opened. In addition, the reverse direction may refer to the direction in which the door arm 143 pushes the door 141. Therefore, if the door arm 143 rotates in the reverse direction, at least a portion of the dust hole 121a may be closed. The forward direction may be the opposite direction to the reverse direction.

[0238] The door arm 143 may connect the door 141 and the door motor 142 , and may open and close the door 141 using power generated by the door motor 142 .

[0239] As an example, the door arm 143 may include a first door arm 143a and a second door arm 143b. One end of the first door arm 143a may be combined with the door motor 142. The first door arm 143a may be rotated by the power of the door motor 142. The other end of the first door arm 143a may be rotatably combined with the second door arm 143b. The first door arm 143a may transmit the force transmitted from the door motor 142 to the second door arm 143b. One end of the second door arm 143b may be combined with the first door arm 143a. The other end of the second door arm 143b may be combined with the door 141. The second door arm 143b may open and close the dust through hole 121a by pushing or pulling the door 141.

[0240] 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 may sense whether the door 141 is in an open state.

[0241] 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.

[0242] Therefore, if the door arm 143 moves to a preset door opening position or the door 141 opens to a specified position, the door opening and closing sensor 144 can sense that the door has been opened. In addition, if the door arm 143 moves to a preset door closing position or the door 141 opens to a specified position, the door opening and closing sensor 144 can sense that the door has been opened.

[0243] 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.

[0244] On the other hand, the door opening / closing sensor 144 may include a non-contact sensor. For example, the door opening / closing sensor 144 may include an infrared sensor (IR sensor).

[0245] With this configuration, the door unit 140 can allow the outside of the first outer wall surface 112 a to communicate with the flow path portion 180 and / or the dust collecting portion 170 by selectively opening and closing at least a portion of the joint surface 121 .

[0246] The door unit 140 may be opened together with the discharge cover 222 of the cleaner 200. In addition, if the door unit 140 is closed, the discharge cover 222 of the cleaner 200 may be closed together with the door unit 140 in conjunction therewith.

[0247] When the dust of the dust bucket 220 of the cleaner 200 is removed, the door motor 142 can couple the discharge cover 222 to the dust bucket body 221 by rotating the door 141. Specifically, the door motor 142 can rotate the door 141 by rotating the door 141, and the rotating door 141 can push the discharge cover 222 toward the dust bucket body 221.

[0248] Reference Figure 3 , Fig.15 as well as Fig.16 , the cover opening unit 150 of the present invention is described as follows.

[0249] 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.

[0250] The cover opening unit 150 may include a push protrusion 151 , a cover opening motor 152 , a cover opening gear 153 , a support plate 154 , and a gear box 155 .

[0251] The push protrusion 151 may move in a manner of pressing the coupling rod 222 c when the cleaner 200 is coupled.

[0252] The push protrusion 151 may be disposed on the dust barrel guide surface 122. Specifically, a protrusion moving hole may be formed on the dust barrel guide surface 122, and the push protrusion 151 may be exposed to the outside through the protrusion moving hole.

[0253] The push protrusion 151 can be arranged at a position that can press the coupling rod 222c 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 push protrusion 151.

[0254] The push protrusion 151 can reciprocate linearly to press the coupling rod 222c. Specifically, the push protrusion 151 can be combined with the gear box 155 to guide the linear movement. The push protrusion 151 can be combined with the cover opening gear 153 and can move together with the movement of the cover opening gear 153.

[0255] The cover opening motor 152 can provide power to move the push protrusion 151. Specifically, the cover opening motor 152 can rotate the motor shaft (not shown) in a forward direction or a reverse direction. Here, the forward direction can refer to the direction in which the push protrusion 151 presses the coupling rod 222c. In addition, the reverse direction can refer to the direction in which the push protrusion 151 pressing the coupling rod 222c is reset to the original position. The forward direction can be the opposite direction to the reverse direction.

[0256] The cover opening gear 153 is combined with the cover opening motor 152, and the power of the cover opening motor 152 can be used to move the push protrusion 151. Specifically, the cover opening gear 153 can be accommodated in the gear box 155. The driving gear 153a of the cover opening gear 153 can be combined with the motor shaft of the cover opening motor 152 to receive power. The driven gear 153b of the cover opening gear 153 can be combined with the push protrusion 151 to move the push protrusion 151. As an example, the driven gear 153b can be set in a rack shape, meshed with the driving gear 153a, and receive power from the driving gear 153a.

[0257] At this time, a torsion spring 222d may be provided on the discharge cover 222. Due to the elastic force of the torsion spring 222d, the discharge cover 222 can be rotated more than a predetermined angle and can be supported at the rotated position. Therefore, the discharge cover 222 can be opened to connect the dust through hole 121a with the interior of the dust bin 220.

[0258] The gear box 155 may be disposed inside the housing 110 , and arranged on the lower side of the coupling portion 120 in the direction of gravity, and accommodate the cover opening gear 153 therein.

[0259] 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.

[0260] The cover opening sensor 155f may be disposed on at least one of the inner side surface and the outer side surface of the gear box 155. As an example, one cover opening sensor 155f may be disposed on the inner side surface of the gear box 155. At this time, the cover opening sensor 155f may sense that the push protrusion 151 is in the initial position.

[0261] As another example, two cover opening sensors 155f may be disposed on the outer side surface of the gear box 155. In this case, the cover opening sensors 155f may sense the initial position of the push protrusion 151 and the cover opening position.

[0262] Therefore, according to the present invention, due to the cover opening unit 150, the user can open the dust container 220 without separately opening the discharge cover 222 of the cleaner, so that the convenience can be improved.

[0263] In addition, when the vacuum cleaner 200 is coupled to the vacuum cleaner base station 100 , the discharge cover 222 is opened, thereby having an effect of preventing dust from scattering.

[0264] On the other hand, referring to Figure 3 and Fig.16 , the dust collecting section 170 is described as follows.

[0265] The vacuum cleaner base station 100 may include a dust collecting unit 170. The dust collecting unit 170 may be disposed inside the cover body 110. The dust collecting unit 170 may be disposed on the lower side of the coupling unit 120 in the direction of gravity.

[0266] As an example, the dust collecting unit 170 may be a dust bag that collects dust sucked from the inside of the dust container 220 of the cleaner 200 by the dust collecting motor 191 .

[0267] The dust collecting portion 170 may be detachably coupled to the cover body 110 .

[0268] Therefore, the dust collecting part 170 can be separated from the cover body 110 and discarded, and a new dust collecting part 170 can be combined with the cover body 110. That is, the dust collecting part 170 can be defined as a consumable part.

[0269] If suction is generated by the dust collecting motor 191 , the dust bag can be increased in volume and contain dust inside.

[0270] For this purpose, the dust bag may be formed of a material that allows air to pass through but prevents foreign matter such as dust from passing through. As an example, the dust bag may be formed of a nonwoven fabric material and may have a hexahedral shape based on the increased volume.

[0271] Therefore, the user does not need to separately bundle a bag or the like for collecting dust, and thus the user's convenience can be improved.

[0272] Different from this, the dust bag may be formed of a permeable material. For example, the dust bag may include a rolled plastic (not shown). With this configuration, if the dust bag is sealed or joined, it is possible to prevent dust or odor trapped inside the dust bag from leaking to the outside of the dust bag. In this case, the dust bag may be mounted to the housing 110 via a dust bag box (not shown). The dust bag may be replaced via the dust bag box as needed.

[0273] On the other hand, referring to Figure 3 and Fig.11 , the flow path portion 180 is described as follows.

[0274] The cleaner base station 100 may include a flow path unit 180 .

[0275] The flow path portion 180 may connect the dust container 220 and the dust collecting portion 170 of the vacuum cleaner 200. The flow path portion 180 may be disposed at the rear side of the joint surface 121. The flow path portion 180 may refer to a space between the dust container 220 and the dust collecting portion 170 of the vacuum cleaner 200. The flow path portion 180 may be a space formed from the dust through hole 121a to the rear side, or may be a flow path formed by bending downward from the dust through hole 121a so that dust and air can flow.

[0276] Specifically, the flow path section 180 may include: a first suction flow path 181, if the vacuum cleaner 200 is combined with the vacuum cleaner base station 100 and the dust through hole 121a is open, the first suction flow path 181 is connected to the internal space of the dust bin 220; and a second suction flow path 182, connecting the first suction flow path 181 and the internal space of the dust collecting section 170.

[0277] As an example, the first suction flow path 181 may be arranged substantially parallel to the axis of the suction motor 214 or the virtual penetration line of the dust container 220 . In this case, the axis of the suction motor 214 or the penetration line of the dust container 220 may penetrate the first suction flow path 181 .

[0278] At this time, the second suction flow path 182 may form a predetermined angle with the first flow path 181. As an example, the first suction flow path 181 and the second suction flow path 182 may be formed at a right angle. With this configuration, the overall volume of the cleaner base station 100 can be minimized.

[0279] The dust in the dust container 220 of the cleaner 200 may move toward the dust collecting portion 170 through the flow path portion 180 .

[0280] On the other hand, referring to Figure 3 and Fig.16 , the dust suction module 190 is described as follows.

[0281] The cleaner base station 100 may include a dust suction module 190. The dust suction module 190 may include a dust collecting motor 191, a first filter 192, and a second filter (not shown).

[0282] The dust collecting motor 191 may be disposed at the lower portion of the dust collecting portion 170. The dust collecting motor 191 may generate suction force toward the flow path portion 180. Thus, the dust collecting motor 191 may provide suction force capable of sucking dust in the dust container 220 of the cleaner 200.

[0283] The dust collecting motor 191 can generate suction force by rotating. As an example, the dust collecting motor 191 can be formed in a shape similar to a cylinder.

[0284] On the other hand, when the cleaner 200 is coupled to the cleaner base station 100 , a cyclonic flow may be generated by the suction force of the dust collecting motor 191 .

[0285] Specifically, when the user couples the vacuum cleaner 200 to the vacuum cleaner base station 100 and operates the dust collecting motor 191 to empty the dust inside the dust barrel 220 , the air sucked in by the suction force of the dust collecting motor 191 through the suction part 212 can generate a cyclonic flow in the cyclone part 213 .

[0286] On the other hand, in the present embodiment, a virtual dust collecting motor axis extending the rotation axis of the dust collecting motor 191 may be formed.

[0287] The first filter 192 may be disposed between the dust collecting portion 170 and the dust collecting motor 191. The first filter 192 may be a pre-filter.

[0288] The second filter (not shown) may be disposed between the dust collecting motor 191 and the outer wall surface 112. The second filter (not shown) may be a high efficiency air (HEPA) filter.

[0289] On the other hand, the vacuum cleaner base station 100 may further include a charging unit 128. The charging unit may be disposed on the coupling portion 120. The charging unit 128 may be electrically connected to the vacuum cleaner 200 coupled to the coupling portion 120. The charging unit 128 may supply power to a battery of the vacuum cleaner 200 coupled to the coupling portion 120.

[0290] In addition, the vacuum cleaner base station 100 may further include a side door (not shown). The side door may be disposed on the cover body 110. The side door may selectively expose the dust collecting unit 170 to the outside. Thus, the user may easily remove the dust collecting unit 170 from the vacuum cleaner base station 100.

[0291] In addition, the vacuum cleaner base station 100 may further include an exhaust port 311. The exhaust port 311 may be formed in the housing 110. For example, the exhaust port 311 may be formed on the lower side of the housing 110 and may be connected to the flow path of the dust collecting motor 191. Therefore, the air passing through the dust collecting motor 191 may be discharged to the outside of the housing 110 via the exhaust port 311.

[0293] Reference Figures 17 to 23 The filter unit 300 of the vacuum cleaner 200 of the present invention is described as follows.

[0294] The vacuum cleaner of the present invention may include a filter unit 300 .

[0295] The filter unit 300 may filter the air exhausted from the cyclone unit 213 .

[0296] The filter unit 300 may guide the air separated from the dust in the cyclone unit 213 to the cyclone module 270. That is, the filter unit 300 may be a mesh filter having a plurality of holes.

[0297] The filter part 300 may include a filter body 310 and filter holes 320 .

[0298] The filter body 310 may be disposed inside the dust barrel 220. Specifically, the filter body 310 may be disposed inside the cyclone portion 213. The cyclone module 270 may be disposed inside the filter body 310. The filter body 310 may be disposed between the cyclone portion 213 and the cyclone module 270.

[0299] The filter body 310 is not limited but may be formed in a cylindrical shape.

[0300] The central axis a5 of the filter body may extend in the up-down direction. The central axis a5 of the filter body may extend in the length direction of the filter body 310 .

[0301] As one example, the central axis a5 of the filter body 310 may be coaxial with the axis a4 of the cyclonic flow. As another example, the central axis a5 of the filter body 310 may be arranged to be parallel to the axis a4 of the cyclonic flow.

[0302] A cyclone flow may be formed along the outer circumference of the filter body 310 .

[0303] The thickness of the filter body 310 may be 0.3 mm to 0.4 mm. At this time, the thickness of the filter body 310 may refer to the distance between the inner side surface 310 a and the outer side surface 310 b at a predetermined position of the filter body 310 .

[0304] The filter body 310 may be formed of at least one material selected from plastic and metal. The filter body 310 may be formed of at least one material selected from plastic and metal.

[0305] The filter hole 320 may guide air toward the inside of the filter body 310. A plurality of the filter holes 320 may be formed along the outer periphery of the filter body 310 in the length direction.

[0306] The filter hole 320 is a hole having a predetermined diameter, and large foreign matter included in the air exhausted from the cyclone part 213 can be filtered by the filter hole 320. Therefore, a plurality of foreign matter such as hair is filtered by the filter hole 320.

[0307] The air passing through the filter hole 320 may flow into the cyclone module 270 disposed inside the filter body 310 .

[0308] At this time, the outside and / or exterior of the filter body 310 may refer to the direction facing the cyclone part 213 based on the filter body 310, and the inside and / or interior of the filter body 310 may refer to the direction facing the cyclone module 270 based on the filter body 310.

[0309] The air flowing into the inside of the filter body 310 through the filter hole 320 may flow in a state tilted inversely to the traveling direction DF of the cyclone flow formed at the inlet side of the filter hole 320. The air passing through the filter hole 320 may pass in a state tilted inversely to the traveling direction DF of the cyclone flow formed at the inlet side of the filter hole 320. This is to prevent a plurality of foreign objects such as hair from getting stuck in the filter hole 320 and reducing the suction force of the cleaner 200.

[0310] At this time, the direction opposite to the traveling direction DF of the cyclonic flow may refer to a direction forming an obtuse angle with respect to the traveling direction DF of the cyclonic flow.

[0311] In addition, the inlet side of the filter hole 320 may refer to a space where air flows from the cyclone part 213 into the filter hole 320. Specifically, the inlet side of the filter hole 320 may refer to a space that becomes a boundary between the filter hole 320 and the cyclone part 213.

[0312] In addition, the outlet side of the filter hole 320 may refer to a space where air is discharged from the filter hole 320 to the cyclone module 270. Specifically, the outlet side of the filter hole 320 may refer to a space that becomes a boundary between the filter hole 320 and the cyclone module 270.

[0313] On the other hand, the cyclone flow generated at the cyclone part 213 may include at least one turning point that changes the traveling direction from flowing along the outside of the filter body 310 to flowing into the inside of the filter body 310 through the filter holes 320 .

[0314] As an example, the traveling direction of the cyclone flow flowing along the outside of the filter body 310 may be changed from the inlet side of the filter hole 320 to the direction of flowing into the inside of the filter body 310 by the suction force of the suction motor 214 .

[0315] As another example, the traveling direction of the cyclone flow flowing along the outside of the filter body 310 may be changed from the inlet side of the filter hole 320 to the direction of flowing into the inside of the filter body 310 by the suction force of the dust collecting motor 191 .

[0316] That is, the cyclone flow generated in the cyclone part 213 can be generated by the suction force of the suction motor 214 when the vacuum cleaner 200 is used alone or by the suction force of the dust collection motor 191 when the vacuum cleaner 200 is combined with the vacuum cleaner base station 100.

[0317] An angle between a first direction D1 , which is an inner direction of the central axis C of the filter hole 320 , and a second direction D2 , which is a tangent direction of the cyclone flow crossing the central axis C of the filter hole 320 , may be an obtuse angle.

[0318] The inner direction of the central axis C of the filter hole 320 may refer to an axial direction of the filter hole 320 toward the inside of the filter body 310 .

[0319] The tangent direction of the cyclone flow may refer to the direction of the cyclone flow tangent to the outer periphery of the filter body 310. Here, the tangent line TL of the cyclone flow may refer to a virtual straight line extending the direction of the cyclone flow at a position intersecting the central axis of the filter hole 320.

[0320] The first direction D1 may be parallel to or coincide with a direction in which air flows into the inside of the filter body 310. The second direction D2 may be parallel to or coincide with a traveling direction DF of a cyclone flow formed at an inlet side of the filter hole 320.

[0321] Reference Fig. 20 and Fig.21 , the angle θ formed by the central axis C of the filter hole 320 and the tangent line TL of the cyclonic flow may be 110 to 150 degrees. As an example, the angle θ1 formed by the first central axis C1 and the tangent line TL of the cyclonic flow may be 113.2 degrees, and the angle θ2 formed by the second central axis C2 and the tangent line TL of the cyclonic flow may be 146.3 degrees. At this time, the angle θ formed by the central axis C of the filter hole 320 and the tangent line TL of the cyclonic flow may increase as it moves from the first central axis C1 toward the second central axis C2.

[0322] Preferably, the angle θ may be 135 degrees. The angle θ may be 110 degrees. The angle θ may be 117.2 degrees. The angle θ may be 121.3 degrees. The angle θ may be 125.5 degrees. The angle θ may be 130.1 degrees. The angle θ may be 141 degrees. The angle θ may be 150 degrees.

[0323] The angle θ between the direction in which air flows into the interior of the filter body 310 through the filter hole 320 and the traveling direction DF of the cyclone flow formed at the inlet side of the filter hole 320 may be an obtuse angle. At this time, the angle θ may be 110 to 150 degrees. Preferably, the angle θ may be 135 degrees. The angle θ may be 110 degrees. The angle θ may be 113.2 degrees. The angle θ may be 117.2 degrees. The angle θ may be 121.3 degrees. The angle θ may be 125.5 degrees. The angle θ may be 130.1 degrees. The angle θ may be 141 degrees. The angle θ may be 146.3 degrees. The angle θ may be 150 degrees.

[0324] The inner surface 320a of the filter hole 320 may be formed to be tilted in the opposite direction relative to the traveling direction DF of the cyclone flow formed at the inlet side of the filter hole 320. The angle θ between the inner surface 320a of the filter hole 320 and the traveling direction DF of the cyclone flow formed at the inlet side of the filter hole 320 may be an obtuse angle. At this time, the angle θ may be 110 to 150 degrees. Preferably, the angle θ may be 135 degrees. The angle θ may be 110 degrees. The angle θ may be 113.2 degrees. The angle θ may be 117.2 degrees. The angle θ may be 121.3 degrees. The angle θ may be 125.5 degrees. The angle θ may be 130.1 degrees. The angle θ may be 141 degrees. The angle θ may be 146.3 degrees. The angle θ may be 150 degrees.

[0325] The inlet side of the filter hole 320 may be configured to be more biased toward the traveling direction DF of the cyclone flow flowing along the outside of the filter body 310 than the outlet side of the filter hole 320 .

[0326] Compared with the second intersection line area I2 where the inner surface of the filter hole and the inner side surface 310a of the filter body intersect, the first intersection line area I1 where the inner surface 320a of the filter hole 320 and the outer side surface 310b of the filter body intersect can be configured to be more biased towards the travel direction DF of the cyclone flow.

[0327] Reference Fig. 22A first penetration line P1 penetrating the first intersection line area I1 in a direction perpendicular to the traveling direction DF of the cyclone flow and a second penetration line P2 penetrating the second intersection line area I2 in a direction perpendicular to the traveling direction DF of the cyclone flow may penetrate the filter body 310 .

[0328] The first penetration line P1 may pass through the inside of the first intersection area I1. The first penetration line P1 may pass through the edge of the first intersection area I1 while being in contact with the edge. The first penetration line P1 may pass through the edge of the second intersection area I2 while being in contact with the edge. The first penetration line P1 may traverse the inside of the filter body 310.

[0329] The second penetration line P2 may pass through the inside of the second intersection area I2. The second penetration line P2 may pass through the edge of the second intersection area I2 while being in contact with the edge. The second penetration line P2 may pass through the edge of the first intersection area I1 while being in contact with the edge. The second penetration line P2 may traverse the inside of the filter body 310.

[0330] like Fig.23 As shown, if the first penetration line P1 and the second penetration line P2 do not penetrate the filter body 310 , a partition space 320 b may be formed in the filter hole 320 to vertically connect the inner space and the outer space of the filter body 310 with respect to the traveling direction DF of the cyclone flow.

[0331] Specifically, a portion of the air flowing into the filter body 310 through the partition space 320b does not form an obtuse angle with respect to the traveling direction DF of the cyclonic flow, so that a plurality of foreign objects such as hair can easily flow into the filter body 310 through the partition space 320b.

[0332] Therefore, if the first penetration line P1 and the second penetration line P2 penetrating the first intersection line region I1 penetrate the filter body 310 , it is possible to prevent the air passing through the filter hole 320 from passing without being inclined at an obtuse angle with respect to the traveling direction DF of the cyclone flow.

[0333] On the other hand, central axes of at least a portion of the plurality of filter holes 320 may be formed to be parallel to each other. In addition, an angle θ of a portion of the plurality of filter holes 320 and an angle θ of another portion may be different from each other.

[0334] Specifically, in the filter holes 320 whose central axes are formed parallel to each other, the angle between the inner direction of the central axis C of each filter hole 320, i.e., the first direction D1, and the tangential direction of the cyclone flow intersecting the central axis C of the filter hole 320 can be an obtuse angle and can be formed differently from each other.

[0335] That is, the central axes of a portion of the multiple filter holes 320 are formed to be parallel to each other, and the tangential direction of the cyclone flow flowing along the outer peripheral surface of the filter body 310 always changes, so the angle between the inner direction of the central axis C of the filter hole 320, i.e., the first direction D1, and the tangential direction of the cyclone flow intersecting the central axis C of the filter hole 320, i.e., the second direction D2, can be different from each other in each filter hole 320.

[0336] on the other hand, Fig.24 A three-dimensional view of a filter unit in a vacuum cleaner is disclosed for illustrating another embodiment of the present invention.

[0337] Reference Fig.24 , a vacuum cleaner according to another embodiment of the present invention may include a filter unit 1300 .

[0339] The filter part 1300 may include a filter body 1310 and a filter hole 1320 .

[0340] The outer surface of the filter body 1310 may be divided into a plurality of regions. The plurality of regions may be differently arranged in a direction of travel of a cyclone flow formed along the outer side of the filter body 1310.

[0341] As an example, a portion of the outer surface of the filter body 1310 can be divided into a first area T1, a second area T2, a third area T3, and a fourth area T4. A virtual straight line perpendicularly connecting the center of the first area T1 and the central axis a15 of the filter body and a virtual straight line perpendicularly connecting the center of the second area T2 and the central axis a15 of the filter body can be located at skew positions to each other. A virtual straight line perpendicularly connecting the center of the second area T2 and the central axis a15 of the filter body and a virtual straight line perpendicularly connecting the center of the third area T3 and the central axis a15 of the filter body can be located at skew positions to each other. A virtual straight line perpendicularly connecting the center of the third area T3 and the central axis a15 of the filter body and a virtual straight line perpendicularly connecting the center of the fourth area T4 and the central axis a15 of the filter body can be located at skew positions to each other.

[0342] The filter hole 1320 may guide air toward the inside of the filter body 1310. A plurality of the filter holes 1320 may be formed along a portion of the outer periphery of the filter body 1310 in the length direction.

[0343] The plurality of filter holes 1320 may be arranged in a plurality of regions divided on the outer surface of the filter body 1310. The plurality of filter holes 1320 may be differently arranged in a direction of travel of a cyclone flow formed along the outer side of the filter body 1310.

[0344] As an example, the filter hole 1320 may include a first filter hole 1321, a second filter hole 1322, a third filter hole 1333, and a fourth filter hole 1334. The first filter hole 1321 may refer to a filter hole configured in the first area T1. The second filter hole 1322 may refer to a filter hole configured in the second area T2. The third filter hole 1323 may refer to a filter hole configured in the third area T3. The fourth filter hole 1324 may refer to a filter hole configured in the fourth area T4.

The control unit 400 may receive a signal indicating that the door 141 is opened from the door opening and closing sensor 137 and determine that the door 141 is opened. If it is determined that the door 141 is opened, the control unit 400 may interrupt the operation of the door motor 142.

[0357] On the other hand, when the dust container 220 is completely emptied, the controller 400 may close the door 141 by rotating the door motor 142 in the reverse direction.
