Description

[Technical Field]

[0001] The present invention relates to a cleaner.[Background Art]

[0002] In general, a cleaner is a home appliance for suctioning small trash or dust in a manner of suctioning air using electricity and filling the same in a dustbin inside a product and is commonly called a vacuum cleaner.

[0003] The vacuum cleaner may be classified into a manual vacuum cleaner for allowing a user to directly perform cleaning while moving the cleaner, and an automatic vacuum cleaner for performing cleaning while traveling by itself. Depending on the type of the vacuum cleaner, the manual vacuum cleaner may be classified into a canister-type vacuum cleaner, an upright vacuum cleaner, a hand vacuum cleaner, a stick-type vacuum cleaner, etc.

[0004] In the past, the canister-type vacuum cleaner was widely used as the household vacuum cleaner, but recently, the hand vacuum cleaner and the stick-type vacuum cleaner, which provide improved convenience of use by integrally providing a dustbin and a cleaner body, are increasingly being used.

[0005] The canister-type vacuum cleaner has a main body and a suction port connected by a rubber hose or a pipe and in some cases, may be used by inserting a brush into the suction port.

[0006] The hand vacuum cleaner is designed to maximize portability and has lightweight and a short length, and thus can have a limited cleaning area. Accordingly, the hand vacuum cleaner is used to clean localized sites, such as on a desk, a sofa, or a vehicle interior.

[0007] A user may use the stick-type vacuum cleaner while standing to enable cleaning without bending down. Accordingly, it is advantageous in cleaning a wide area while moving. While the hand vacuum cleaner cleans narrow spaces, the stick-type vacuum cleaner may clean wider spaces and clean high places out of reach. Recently, the stick-type vacuum cleaner has been provided in a module type to allow users to actively change a vacuum cleaner type for various purposes.

[0008] Meanwhile, Korean Patent Laid-Open Application No. 10-2098784 discloses a cleaner.

[0009] The cleaner disclosed in the patent document may include a filter unit for filtering dust from air discharged from a cyclone unit and a moving unit for removing dust from an outer surface of the filter unit while moving in a linear direction.

[0010] However, the patent document discloses only a structure for removing dust accumulated on an outer surface of a single filter for filtering dust from air introduced through a suction unit and does not disclose a structure for removing dust accumulated on an outer surface of each filter in a cleaner provided with a plurality of filters.

[0011] In particular, when the plurality of filters are disposed inside a main body above a dustbin, it is difficult for a user to easily remove and clean the filter. That is, when a separate filter is disposed inside the main body in addition to the filter unit disclosed in the patent document, the user needs to first remove the dustbin and a second cyclone unit from the main body to clean the filter, which is cumbersome.[Disclosure] [Technical Problem]

[0012] The present invention has been made in efforts to solve the above problems and is directed to providing a cleaner capable of removing dust accumulated in at least one filter with only a simple operation of a user pushing or pulling an operation unit.

[0013] In addition, the present invention is directed to providing a cleaner capable of improving filtration performance of a filter and suction performance by a suction motor by directly sweeping a surface on which dust accumulates among outer and inner surfaces of each filter.

[0014] In addition, the present invention is directed to providing a cleaner capable of preventing dust stored inside a dustbin from being scattered to the outside through an open upper side of the dustbin when a user pulls or pushes an operation unit to remove the dustbin from a support of a main body housing.

[0015] In addition, the present invention is directed to providing a cleaner in which a second cleaning member is connected to a dustbin and an operation unit is fixed to the dustbin, thereby enabling the dustbin in which a first cleaning member is disposed to move more stably when a user pulls or pushes the operation unit.

[0016] In addition, the present invention is directed to providing a cleaner in which a second cleaning member is connected to an operation unit and the operation unit is fixed to a dustbin, thereby enabling the second cleaning member to move without shaking when a user pulls or pushes the operation unit, thereby improving operability.

[0017] In addition, the present invention is directed to providing a cleaner which may have a structure in which a first cleaning member for sweeping dust accumulated in a first filter, a second cleaning member for sweeping dust accumulated in a second filter, and a third cleaning member for sweeping dust accumulated in a third filter are connected to each other, thereby removing dust accumulated in each filter by only moving an operation unit.

[0018] In addition, the present invention is directed to providing a cleaner in which a second filter and / or a third filter are connected to an operation unit, and the operation unit is disposed separately from a dustbin, so that dust accumulated in the second filter and / or the third filter can be removed when a user pulls or pushes only the operation unit.[Technical Solution]

[0059] FIG. 1 is a perspective view of a cleaner according to a first embodiment of the present invention, FIG. 2 is a cross-sectional view of the cleaner according to the first embodiment of the present invention, FIG. 3 is a view illustrating a state in which an operation unit is pulled in FIG. 2, FIG. 4 is a view illustrating a state in which an anti-scattering unit is removed from FIG. 3, and FIG. 5 is a view for describing the detailed configuration of a first cleaning member and a second cleaning member of the cleaner according to the first embodiment of the present invention.

[0060] A cleaner 1 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 5 as follows.

[0061] The cleaner 1 may be a cleaner which is manually operated by a user. For example, the cleaner 1 may be a hand cleaner or a stick cleaner.

[0062] Meanwhile, in one embodiment of the present invention, a direction of the cleaner 1 may be defined with respect to when a bottom surface (lower surface) of a battery housing 160 is placed on the ground.

[0063] In this case, the term "front" may be a direction in which a suction unit 120 is disposed with respect to a suction motor 140, and the term "rear" may be a direction in which a handle 150 is disposed with respect to the suction motor 140. In addition, a direction disposed at the right side may be referred to as a right side, and a direction disposed at the left side may be referred to as a left side based on when viewing the suction unit 120 from the suction motor 140. In addition, in one embodiment of the present invention, upper and lower sides may be defined in a direction perpendicular to the ground with respect to when the bottom surface (lower surface) of the battery housing 160 is placed on the ground.

[0064] The cleaner 1 may include a main body 100. The main body 100 may include a main body housing 110, a suction unit 120, a first cyclone unit 130, the suction motor 140, the handle 150, and an operation unit (not illustrated).

[0065] The main body housing 110 may form an exterior of the cleaner 1. The main body housing 110 may provide a space in which the suction motor 140 and a second filter 700 may be accommodated. The main body housing 110 may be formed in a shape similar to a cylinder.

[0066] The suction unit 120 may be disposed inside a dustbin 200. For example, the suction unit 120 may be formed in a pipe shape having an open interior. The suction unit 120 may be coupled to an extension pipe (not illustrated). The suction unit 120 may provide a suction flow path 120a through which air including dust may flow.

[0067] The suction unit 120 may be coupled to a second cyclone unit 400. The suction unit 120 may be coupled to a case 310 of the second cyclone unit 400 to be described below.

[0068] At least a portion of the suction unit 120 may be disposed inside the second cyclone unit 400. Specifically, at least a portion of the suction unit 120 may be disposed to be surrounded by a plurality of cyclone bodies 410. Accordingly, the at least a portion of the suction unit 120 may extend in a direction that is the same as or parallel to a direction in which a suction motor axis line a1 extends.

[0069] The suction unit 120 may be formed in a bent shape. One end portion of the suction unit 120 may be formed to pass through a cover main body 221 of a discharge cover 220. The other end portion of the suction unit 120 may be formed to pass through an outer circumferential surface of the second cyclone unit 400 (outer circumferential surface of the case 310 or a first filter 320). Accordingly, air suctioned from the outside by the suction unit 120 may flow through the suction flow path 120a and may be discharged into the dustbin 200.

[0070] The cleaner 1 according to the embodiment of the present invention may be provided with at least one cyclone unit capable of separating dust by a cyclonic flow. For example, the cleaner 1 may include the first cyclone unit 130 and the second cyclone unit 400.

[0071] The first cyclone unit 130 employs the principle of a dust collector that uses a centrifugal force to separate the dust suctioned into the main body 100 by the suction unit 120. That is, the first cyclone unit 130 may refer to a space in which a cyclonic flow circulating along an inner circumferential surface of the dustbin 200, and the first cyclone unit 130 may refer to a portion of a space inside the dustbin 200.

[0072] The first cyclone unit 130 may communicate with the suction unit 120. The first cyclone unit 130 may separate the dust suctioned therein through the suction unit 120. The space inside the first cyclone unit 130 may communicate with the space inside the dustbin 200.

[0073] The cyclonic flow generated by the first cyclone unit 130 may be generated by a suction force of the suction motor 140.

[0074] The cyclonic flow generated by the first cyclone unit 130 may be formed between an inner surface of the dustbin 200 and an outer surface of the case 310 to be described below. That is, the cyclonic flow may be formed inside the first cyclone unit 130.

[0075] A space inside the first cyclone unit 130 may communicate with the suction unit 120. Since the air and dust suctioned through the suction unit 120 may flow along the inner circumferential surface of the first cyclone unit 130, a cyclonic flow may be generated in the space inside the cyclone unit 130.

[0076] As an example, the cyclonic flow generated by the first cyclone unit 130 may be formed to surround the dustbin 200 along a circular path on an inner circumference of the dustbin 200. Since the air suctioned through the suction unit 120 flows along the circular path on the inner circumferential surface of the dustbin 200 about a dustbin center axis a2, the cyclonic flow may be generated in the space inside the first cyclone unit 130.

[0077] Specifically, when an axis a3 of the cyclonic flow generated by the first cyclone unit 130 is disposed perpendicular to a lower side in the direction of gravity, the air suctioned through the suction unit 120 may flow along the circular path on the inner circumferential surface of the dustbin 200 about the dustbin center axis a2. Alternatively, when the axis a3 of the cyclonic flow generated by the first cyclone unit 130 is disposed parallel to the ground, the air suctioned through the suction unit 120 may flow along the circular path on the inner circumferential surface of the dustbin 200 about the dustbin center axis a2.

[0078] As another example, the cyclonic flow generated by the first cyclone unit 130 may be formed along a spiral path on the inner circumference of the dustbin 200. That is, since the air suctioned through the suction unit 120 may flow along the spiral path on the inner circumference of the dustbin 200, the cyclonic flow may be generated in the space inside the first cyclone unit 130.

[0079] Specifically, when the axis a3 of the cyclonic flow generated by the first cyclone unit 130 is tilted with respect to the ground, the air suctioned through the suction unit 120 may flow along the spiral path on the inner circumference of the dustbin 200.

[0080] The cleaner 1 according to the embodiment of the present invention may include the second cyclone unit 400 for re-separating dust from air discharged from the first cyclone unit 130. That is, the second cyclone unit 400 may filter small dust not removed by the first cyclone unit 130 and a first filter unit 300 from the air passing through the first cyclone unit 130 and the first filter unit 300.

[0081] In this case, the second cyclone unit 400 may be positioned inside the first cyclone unit 130 to minimize the size of the cleaner 1. The second cyclone unit 400 may be disposed below the suction motor 140. Specifically, the second cyclone unit 400 may be disposed inside the first filter unit 300. That is, the first cyclone unit 130 and the second cyclone unit 400 may be disposed inside the dustbin 200 with the first filter unit 300 interposed therebetween.

[0082] The second cyclone unit 400 may include a plurality of cyclone bodies 410 disposed in parallel. Accordingly, the air discharged from the first cyclone unit 130 may pass through a plurality of cyclone bodies 410 through the first filter unit 300. That is, the cyclonic flow generated by the second cyclone unit 400 may be formed inside the cyclone body 410.

[0083] Meanwhile, the second cyclone unit 400 may include a single cyclone body 410, and even in this case, the axis a3 of the cyclonic flow generated by the second cyclone unit 400 may extend in a vertical direction.

[0084] In addition, the axis a3 of the cyclonic flow generated by the first cyclone unit 130 may also extend in the vertical direction. Accordingly, the axis a3 of the cyclonic flow generated by the first cyclone unit 130 and the axis a3 of the cyclonic flow generated by the second cyclone unit 400 are formed coaxially or in parallel in the vertical direction.

[0085] A storage member 311 in which the dust separated by the second cyclone unit 400 is stored may be disposed inside the dustbin 200. The storage member 311 may be connected to a lower side of the case 310 and may be in contact with an upper surface of the discharge cover 220. In addition, a lower side of the storage member 311 may be open.

[0086] The storage member 311 may partition the space inside the dustbin 200 into a first dust storage portion 311a in which the dust separated from the first cyclone unit 130 is stored, and a second dust storage portion 311b in which the dust separated from the second cyclone unit 400 is stored.

[0087] Accordingly, the space between the storage member 311 and the dustbin 200 may be defined as the first dust storage portion 311a, and a lower internal space of the storage member 311 may be defined as the second dust storage portion 311b.

[0088] The discharge cover 220 may open and close both the first dust storage portion and the second dust storage portion. That is, both the first dust storage portion and the second dust storage portion may be exposed to the outside.

[0089] The suction motor 140 may generate a suction airflow that suctions air. The suction motor 140 may be accommodated in the main body housing 110.

[0090] The suction motor 140 may generate a suction force through its rotation. As an example, the suction motor 140 may be provided in a shape similar to a cylindrical shape.

[0091] In this case, a cyclonic flow may be generated by the suction force of the suction motor 140.

[0092] Specifically, when the suction motor 140 is operated, the air suctioned through the suction unit 120 by the suction force of the suction motor 140 may generate the cyclonic flow in the first cyclone unit 130 and / or the second cyclone unit 400.

[0093] The cleaner of the present invention may include a virtual suction motor axis line a1 extending a rotational axis of the suction motor 140. The suction motor axis line a1 may be disposed coaxially or parallel to the dustbin center axis a2, the cyclonic flow axis a3, and the case center axis a4.

[0094] The suction motor 140 may be positioned inside the main body housing 110. In addition, at least a portion of the suction motor 140 may be positioned above the second cyclone unit 400. Accordingly, the suction motor 140 may be positioned above the dustbin 200.

[0095] The suction motor 140 may be connected to an outlet of the second cyclone unit 400.

[0096] The cyclonic flow axis a3 of the first cyclone unit 130 may pass through the suction motor 140.

[0097] In the embodiment of the present invention, when the suction motor 140 is positioned above the second cyclone unit 400, the air discharged from the second cyclone unit 400 may flow directly toward the suction motor 140, thereby minimizing a flow path between the second cyclone unit 400 and the suction motor 140.

[0098] An air outlet 110a through which the air suctioned by the suction force of the suction motor 140 is discharged may be formed in the main body housing 110.

[0099] A flow guide may be disposed in the main body housing 110. The flow guide may guide a flow of the air discharged through the air outlet 110a.

[0100] The handle 150 may be gripped by a user. For example, the handle 150 may be formed in a shape similar to a cylindrical shape. Alternatively, the handle 150 may be formed in a curved cylindrical shape. The handle 150 may be disposed at a predetermined angle with the main body housing 110, the suction motor 140, or the first cyclone unit 130.

[0101] The handle 150 may include a grip portion formed in the form of a pillar to allow the user to grip the same, a first extension connected to one end portion in a longitudinal direction (axial direction) of the grip portion and formed to extend toward the suction motor 140, and a second extension connected to the other end portion in the direction (axial direction) of the grip portion and formed to extend toward the dustbin 200.

[0102] Meanwhile, in the present embodiment, a virtual grip portion through line formed to extend in a longitudinal direction of the grip portion (axial direction of a pillar) and passing through the grip portion may be formed.

[0103] For example, the grip portion through line may be a virtual line formed inside the cylindrical handle 150 and may be a virtual line formed parallel to at least a portion of an outer surface (outer perimetric surface) of the grip portion.

[0104] An upper surface of the handle 150 may form a partial exterior of an upper surface of the cleaner 1. Accordingly, when the user grips the handle 150, one component of the cleaner 1 can be prevented from coming into contact with a user's arm.

[0105] The first extension may extend from the grip portion toward the main body housing 110 or the suction motor 140. At least a portion of the first extension may extend in a horizontal direction.

[0106] The second extension may extend from the grip portion toward the dustbin 200. At least a portion of the second extension may extend in the horizontal direction.

[0107] The operation unit (not illustrated) may be disposed in the main body housing 110. The operation unit (not illustrated) may be disposed on an outer surface of the main body housing 110. The operation unit (not illustrated) may be composed of a plurality of buttons, and when the user presses a corresponding button, a corresponding command may be performed. The user may input an operation or stop command of the cleaner 1 through the operation unit (not illustrated).

[0108] The cleaner 1 may include the dustbin 200. The dustbin 200 may communicate with the suction unit 120. The first cyclone unit 130 may be positioned inside the dustbin 200. The dustbin 200 may store the dust separated by the first cyclone unit 130.

[0109] The dustbin 200 may include a dustbin main body 210, the discharge cover 220, a dustbin compression lever (not illustrated), and a compression member (not illustrated).

[0110] The dustbin main body 210 may provide a space in which the dust separated by the first cyclone unit 130 may be stored. For example, the dustbin main body 210 may be formed in a shape similar to a cylindrical shape.

[0111] Meanwhile, in the present embodiment, the virtual dustbin central axis a2, which passes through the inside (internal space) of the dustbin main body 210 and is formed to extend in the longitudinal direction (i.e., an axial direction in the cylindrical dustbin main body 210) of the dustbin main body 210, may be formed.

[0112] A portion of a lower surface (bottom surface) of the dustbin main body 210 may be opened. In addition, a lower surface extension (not illustrated) may be formed on the lower surface (bottom surface) of the dustbin main body 210. The lower surface extension may be formed to cover a portion of the lower surface of the dustbin main body 210.

[0113] The dustbin 200 may include the discharge cover 220. The discharge cover 220 may be disposed on the lower surface of the dustbin 200.

[0114] The discharge cover 220 may be provided to open and close one end portion of the dustbin main body 210 in the longitudinal direction. Specifically, the discharge cover 220 may selectively open and close a lower portion of the dustbin 200 that is open downward.

[0115] The discharge cover 220 may include the cover main body 221 and a hinge unit 222. The cover main body 221 may be formed to cover a portion of the lower surface of the dustbin main body 210. The cover main body 221 may rotate downward about the hinge unit 222. The hinge unit 222 may be disposed adjacent to the battery housing 160. The hinge unit 222 may have a torsion spring. Accordingly, when the discharge cover 220 is separated from the dustbin main body 210, the cover main body 221 may be supported while rotated about the hinge unit 222 at a predetermined angle or more in the dustbin main body 210 by an elastic force of the torsion spring.

[0116] The discharge cover 220 may be coupled to the dustbin 200 through hook coupling. Meanwhile, the discharge cover 220 may be separated from the dustbin 200 through a coupling lever (not illustrated). The coupling lever (not illustrated) may be disposed at the front of the dustbin 200. Specifically, the coupling lever (not illustrated) may be disposed on a front outer surface of the dustbin 200. When an external force is applied, the coupling lever (not illustrated) may elastically deform a hook formed to extend from the cover main body 221 to release the hook coupling between the cover main body 221 and the dustbin main body 210.

[0117] When the discharge cover 220 is closed, the lower surface of the dustbin 200 may be covered (sealed) by the discharge cover 220 and the lower surface extension.

[0118] The dustbin 200 may include the dustbin compression lever. The dustbin compression lever may be disposed outside the dustbin 200. The dustbin compression lever may be disposed to move upward and downward outside the dustbin 200. The dustbin compression lever may be connected to the compression member (not illustrated). When the dustbin compression lever is moved downward by an external force, the compression member (not illustrated) may also move downward. Accordingly, user convenience can be provided. The compression member (not illustrated) and the dustbin compression lever may be returned to their original positions by an elastic member (not illustrated). Specifically, when the external force applied to the dustbin compression lever is released, the elastic member may move the dustbin compression lever and the compression member (not illustrated) upward.

[0119] The compression member (not illustrated) may be disposed inside the dustbin main body 210. The compression member may move in the space inside the dustbin main body 210. Specifically, the compression member may move upward and downward in the dustbin main body 210. Accordingly, the compression member may compress the dust in the dustbin main body 210 downward. In addition, when the discharge cover 220 is separated from the dustbin main body 210 and the lower portion of the dustbin 200 is opened, the compression member may move from the upper portion to the lower portion of the dustbin 200 to remove foreign substances such as the remaining dust and the like in the dustbin 200. Accordingly, it is possible to increase the suction force of the cleaner by preventing the remaining dust from remaining in the dustbin 200. In addition, bad odors generated by the residue can be removed by preventing the remaining dust from remaining in the dustbin 200.

[0120] The cleaner 1 may include the battery housing 160. A battery 161 may be accommodated in the battery housing 160. The battery housing 160 may be disposed below the handle 150. For example, the battery housing 160 may have a hexahedral shape having an open lower portion. An upper surface of the battery housing 160 may be connected to the handle 150.

[0121] The battery housing 160 may include an accommodation portion which is opened downward. The battery 161 may be detachably attached through the accommodation portion of the battery housing 160.

[0122] The battery housing 160 may have a battery terminal exposed to the outside.

[0123] When the battery terminal of the battery housing 160 is coupled to an external charging terminal (not illustrated), electric power may be supplied to the battery 161 through the battery terminal. The battery terminals may be disposed to be spaced apart from each other in a left-right direction on a lower surface of the battery housing 160.

[0124] The cleaner 1 may include the battery 161.

[0125] For example, the battery 161 may be detachably coupled to the cleaner 1. The battery 161 may be detachably coupled to the battery housing 160. For example, the battery 161 may be inserted into the battery housing 160 from the bottom of the battery housing 160. With this configuration, it is possible to improve the portability of the cleaner 1.

[0126] Alternatively, the battery 161 may be integrally provided inside the battery housing 160. In this case, a lower surface of the battery 161 is not exposed to the outside.

[0127] The battery 161 may store electric energy and supply electric power to components in addition to the suction motor 140 of the cleaner 1. The battery 161 may be disposed below the handle 150. The battery 161 may be disposed at the lower side of the dustbin 200. That is, the suction motor 140 and the battery 161 may be disposed not to overlap each other in the front-rear direction, and their heights may also be disposed differently. With respect to the handle 150, the heavy suction motor 140 may be disposed above the handle 150, and the light battery 161 may be disposed below the handle 150, and thus the weight of the cleaner 1 may be entirely distributed evenly. Accordingly, when the user performs cleaning using the handle 150, it is possible to prevent strain on the user's wrist.

[0128] According to the embodiment, when the battery 161 is coupled to the battery housing 160, the lower surface of the battery 161 may be exposed to the outside. Since the battery 161 may be disposed on the floor when the cleaner 1 is disposed on the floor, the battery 161 may be immediately separated from the battery housing 160. In addition, since the lower surface of the battery 161 is exposed to the outside and comes into direct contact with external air of the battery 161, cooling performance of the battery 161 can be improved.

[0129] Meanwhile, when the battery 161 is integrally fixed to the battery housing 160, a structure for detachably attaching the battery 161 to the battery housing 160 can be smaller, thereby reducing the overall size of the cleaner 1 and achieving lightweight.

[0130] The cleaner 1 may include the extension pipe (not illustrated). The extension pipe (not illustrated) may communicate with a cleaning module (not illustrated). The extension pipe (not illustrated) may communicate with the main body 100. The extension pipe (not illustrated) may communicate with the suction unit 120 of the main body 100. The extension pipe (not illustrated) may be formed in a long cylindrical shape.

[0131] The main body 100 may be connected to the extension pipe (not illustrated). The main body 100 may be connected to the cleaning module through the extension pipe (not illustrated). The main body 100 may generate the suction force through the suction motor 140 and provide the suction force to the cleaning module through the extension pipe (not illustrated). External dust may flow into the main body 100 through the cleaning module and the extension pipe (not illustrated).

[0132] The cleaner 1 may include the cleaning module (not illustrated). The cleaning module (not illustrated) may communicate with the extension pipe (not illustrated). Accordingly, external air may pass through the cleaning module (not illustrated) and the extension pipe (not illustrated) and flow into the main body 100 of the cleaner 1 by the suction force generated from the main body 100 of the cleaner 1.

[0133] The cleaner 1 may include the first filter unit 300. The first filter unit 300 may filter the air discharged from the first cyclone unit 130. The first filter unit 300 may guide air from which dust has been separated while passing through the first cyclone unit 130 to the second cyclone unit 400.

[0134] The first filter unit 300 may include the case 310 and the first filter 320.

[0135] The case 310 may be disposed inside the dustbin 200. The case 310 may be disposed inside the first cyclone unit 130.

[0136] A space may be formed inside the case 310. The second cyclone unit 400 may be disposed inside the case 310.

[0137] The case 310 is not limited, but may be formed in a cylindrical shape.

[0138] The case center axis a4 may extend in the vertical direction. The case center axis a4 may extend in the longitudinal directions of the case 310.

[0139] For example, the case center axis a4 may be formed coaxially with the axis a3 of the cyclonic flow generated from the first cyclone unit 130. As another example, the case center axis a4 may be formed parallel to the axis a3 of the cyclonic flow generated from the first cyclone unit 130. As still another example, the center axis a4 of the case 310 may be formed coaxially with the suction motor axis line a1.

[0140] The first filter 320 may filter dust from the air discharged from the first cyclone unit 130.

[0141] The first filter 320 may have a plurality of holes having a predetermined diameter. Accordingly, large foreign substances contained in the air discharged from the first cyclone unit 130 may be filtered by the first filter 320.

[0142] The first filter 320 may be disposed in the case 310. Alternatively, the first filter 320 may be a portion of the case 310. Alternatively, a lower edge of the first filter 320 may be coupled to the case 310.

[0143] The air passing through the first filter 320 may flow into the second cyclone unit 400 disposed inside the case 310.

[0144] In this case, an outer side and / or outer portion of the case 310 may refer to a direction facing the first cyclone unit 130 with respect to the case 310, and an inner side and / or inner portion of the case 310 may refer to a direction facing the second cyclone unit 400 with respect to the case 310.

[0145] The cleaner according to the embodiment of the present invention may include the second cyclone unit 400.

[0146] At least a portion of the second cyclone unit 400 may be disposed inside the first cyclone unit 130 and may separate dust from the air discharged from the first cyclone unit 130. After dust is separated from the air by the first cyclone unit 130, the air discharged from the first cyclone unit 130 may flow into the second cyclone unit 400 along a flow path.

[0147] The second cyclone unit 400 may be composed of a set of axial flow cyclones formed to separate dust from air introduced in the axial direction.

[0148] The second cyclone unit 400 may include a cyclone body 410, a vortex finder 420, and a band member 430.

[0149] The cyclone body 410 employs the principle of a dust collector that uses a centrifugal force to separate dust from the air passing through the first filter unit 300. Specifically, the cyclone body 410 may separate dust from the air passing through the first filter 320 using the cyclonic flow. Since a space in which air may flow may be formed inside the cyclone body 410, the air passing through the first filter 320 may flow into the cyclone body 410.

[0150] The cyclone body 410 may be disposed inside the case 310. Specifically, at least a portion of the cyclone body 410 may be disposed inside the case 310, and the air passing through the first filter 320 may flow into the cyclone body 410.

[0151] The cyclone body 410 may be provided as a plurality of cyclone bodies. An inlet forming an outer wall of a circumference of a hollow may be formed on each cyclone body 410. The outer walls of the circumference of the hollow formed by the cyclone body 410 may correspond to outer walls of the axial flow cyclones. The air discharged from the first cyclone unit 130 may flow into the cyclone body 410 through the inlet. Air circulating along an inner circumferential surface of the cyclone body 410 may form a cyclonic flow.

[0152] Dust heavier than air may rotate in a swirling flow having a radius of rotation larger than that of air. Since the dust rotates inside the cyclone body 410, a maximum rotation radius of the dust may be defined by the cyclone body 410.

[0153] A lower portion of the cyclone body 410 may have an inclined shape that narrows downward. The reason why the lower portion of the cyclone body 410 has a shape that narrows downward is to guide dust separated from the air to fall and prevent the dust from being discharged into the vortex finder 420 along the air.

[0154] An outlet may be formed on the lower portion of the cyclone body 410. That is, dust separated from the air inside the cyclone body 410 may be discharged from the cyclone body 410 through the outlet. In addition, the lower portion of the cyclone body 410 may communicate with the space inside the storage member 311. Accordingly, dust rotating along the swirling flow inside the cyclone body 410 may fall and may be stored in the storage member 311. The dust stored in the storage member 311 may communicate with an external space when the discharge cover 220 is opened.

[0155] An upper portion of the cyclone body 410 may be formed to accommodate the vortex finder 420. The upper portion of the cyclone body 410 may be formed to have a constant inner diameter. The upper and lower portions of the cyclone body 410 may be defined with respect to a position at which the inner diameter narrows.

[0156] The outer circumferential surface of each cyclone body 410 may be connected in contact with the nearby cyclone body 410 to allow the plurality of cyclone bodies 410 to form one member. A cross section of each cyclone body 410 preferably has a circular shape as illustrated in the drawing. This is because, when the cross section of the cyclone body 410 is formed in a circular shape, a flow path of air and dust may be formed between the outer circumferential surfaces of adjacent cyclone bodies 410 even when they are in close contact with each other. When the flow path of air and dust is formed between the cyclone bodies 410, there is an advantage in that a separate flow path structure does not need to be installed.

[0157] The cross section of each cyclone body 410 may be formed in a polygonal shape. However, even when the cross section of each cyclone body 410 is formed in a polygonal shape, the cross section of the each cyclone body 410 is preferably formed in a polygonal shape so that the flow path of air and dust may be formed.

[0158] The vortex finder 420 discharges air passing through the cyclonic flow inside the cyclone body 410.

[0159] A flow path through which air may flow may be formed inside the vortex finder 420. The vortex finder 420 may be provided as a plurality of vortex finders, and at least a portion of each vortex finder 420 may be disposed inside each cyclone body 410. An outer circumferential surface of each vortex finder 420 may be spaced apart from the inner circumferential surface of each cyclone body 410. Each vortex finder 420 may have an inlet forming the outer wall of the circumference of the hollow, and the air passing through the cyclone body 410 may be discharged through the inlet of each vortex finder 420. In addition, the air flowing into the inlet of the vortex finder 420 may flow upward and may be discharged through the outlet of the vortex finder 420.

[0160] A lower portion of the vortex finder 420 may have a greater height than the band member 430. However, an upper portion of the vortex finder 420 may have the same height as the band member 430. A lower end of the vortex finder 420 may protrude downward from the band member 430, but an upper end thereof may not be the case.

[0161] A cross section of each vortex finder 420 preferably has a circular ring shape. The cross section of each vortex finder 420 may be formed in a polygonal shape. However, even when the cross section of each vortex finder 420 is formed in a polygonal shape, the cross section of each vortex finder 420 is preferably formed in a polygonal shape so that the flow path of air and dust may be formed.

[0162] The band member 430 may be formed to surround the outer circumferential surface of the vortex finder 420. In this case, the band member 430 may be named differently as needed. For example, names, such as a ring portion, a ring portion, an edge portion, a perimeter portion, a circle portion, a support portion, a connection portion, an outer portion, a cyclone boundary portion, an outer wall portion, etc., may be considered, and other names are also possible.

[0163] The band member 430 may be seated on the filter body 320 and may have a shape corresponding to the upper portion of the first filter 320. An upper edge of the first filter 320 may be formed in a circular shape, and the band member 430 may also be formed in a circular shape surrounding the vortex finder 420. However, the upper portion of the first filter 320 and the band member 430 may be formed in a polygonal shape.

[0164] A guide vane (not illustrated) guides the air discharged from the first cyclone unit 130 into the cyclone body 410. The guide vane (not illustrated) may form a flow path through which the air introduced through the inlet may flow into the cyclone body 410. Accordingly, that is, the air flowing along the flow path formed by the guide vane (not illustrated) may form a swirling flow between the vortex finder 420 and the cyclone body 410.

[0165] At least a portion of the guide vane (not illustrated) may be disposed between the cyclone body 410 and the vortex finder 420 and connected to each cyclone body 410 and each vortex finder 420. One side of the guide vane (not illustrated) may be connected to an outer surface of the vortex finder 420 in a spiral direction, and the other side of the guide vane (not illustrated) may be connected to an inner surface of the cyclone body 410 in the spiral direction.

[0166] The guide vane (not illustrated) may be provided as a plurality of guide vanes on each cyclone body 410 and each vortex finder 420, and the guide vane (not illustrated) may extend in the spiral direction to generate a swirling flow. As the guide vane (not illustrated) extends in the spiral direction, the air and dust flowing into the inlet of the cyclone body 410 may form a swirling flow.

[0167] Hereinafter, a flow of the air flowing through the flow path of the cleaner 1 according to the embodiment of the present invention will be described.

[0168] First, when the suction motor 140 operates, external air may flow into the dustbin 200 through the suction unit 120.

[0169] The air from which dust has been separated by the first cyclone unit 130 inside the dustbin 200 may flow into the cyclone body 410 through the first filter 320. The air flowing into the cyclone body 410 may fall while forming the swirling flow, flow upward, and pass through the vortex finder 420. The air passing through the vortex finder 420 may have dust filtered by the second filter 700 disposed above the second cyclone unit 400. The air from which dust has been filtered by the second filter 700 may flow toward the suction motor 140 disposed downstream of a suction airflow. The air passing through the suction motor 140 may be discharged to the outside through the air outlet 110a after passing through a third filter 800.

[0170] The cleaner 1 according to the first embodiment of the present invention may include the main body 100, the dustbin 200, the suction unit 120, the first filter 320, the second filter 700, an operation unit 500, a first cleaning member 610, and a second cleaning member 620.

[0171] The first filter 320 may be disposed inside the dustbin 200 and may filter dust from air introduced through the suction unit 120. As the external air introduced through the suction unit 120 may flow into the first cyclone unit 130 and the air discharged from the first cyclone unit 130 passes through the first filter 320, dust may be filtered from the air. The first filter 320 may be a pre-filter.

[0172] The first filter 320 may be spaced apart from the second cyclone unit 400 and formed to surround the second cyclone unit 400. For example, the first filter 320 may be formed in a shape similar to a cylinder having an open interior.

[0173] The second filter 700 may be disposed inside the main body housing 110 and may filter dust from the air passing through the first filter 320. As the air passing through the first filter 320 flows into the second cyclone unit 400 and the air discharged from the second cyclone unit 400 passes through the second filter 700, dust may be filtered from the air.

[0174] The second filter 700 may be formed in a shape similar to a cylinder having an open interior.

[0175] The operation unit 500 may be disposed outside the dustbin 200 and may move together with the dustbin 200. The operation unit 500 may be formed in a ring shape so that the user may grip the operation unit. When the user grips the operation unit 500 and pulls the operation unit 500 outward, the dustbin 200 to which the operation unit 500 is fixed moves outward.

[0176] The first cleaning member 610 may be disposed inside the dustbin 200 and may sweep the first filter 320 when the operation unit 500 moves. The first cleaning member 610 may be a brush including a plurality of bristles.

[0177] The first cleaning member 610 may be fixed inside the dustbin 200 and may move together with the dustbin 200. The first cleaning member 610 may move linearly in the longitudinal direction of the first filter 320. An inner diameter of the first cleaning member 610 may correspond to an outer diameter of the first filter 320. Accordingly, when the user grips the operation unit 500 and pulls or pushes the operation unit 500 outward or inward, the first cleaning member 610 may move linearly together with the dustbin 200. In addition, the first cleaning member 610 may sweep dust accumulated on the first filter surface, which is the outer surface of the first filter 320, while moving.

[0178] The second cleaning member 620 may sweep the second filter 700 when the operation unit 500 moves.

[0179] The second cleaning member 620 may be connected to the dustbin 200. Specifically, a transfer unit 900 may connect the second cleaning member 620 to the dustbin 200. Accordingly, this structure has the advantage of allowing the dustbin 200 to move more stably when the user pulls or pushes the operation unit 500.

[0180] The transfer unit 900 may extend in the longitudinal direction of the second filter 700. The transfer unit 900 may extend along the suction motor axis line a1.

[0181] The second cleaning member 620 may include a moving unit 621 and a brush 622.

[0182] The moving unit 621 may be formed in a shape similar to a cylinder having an open interior.

[0183] The moving unit 621 may move along a space between the outer side of the second filter 700 and the inner side of the main body housing 110 while surrounding the second filter 700.

[0184] The moving unit 621 may be connected to the dustbin 200 by the transfer unit 900. The transfer unit 900 may be disposed parallel to the suction motor axis line a1.

[0185] The brush 622 may be disposed on an inner perimetric surface of the moving unit 621. The brush 622 may include a plurality of bristles. The brush 622 may be disposed in contact with the second filter 700.

[0186] The dust filtered by the first filter 320 may accumulate on the first filter surface. The first filter surface may be an outer surface of the first filter 320. The air discharged from the first cyclone unit 130 may flow into the second cyclone unit 400 after dust is filtered through the first filter surface.

[0187] The air passing through the first filter 320 may flow from the outside to the inside of the first filter 320. The air discharged from the first cyclone unit 130 may start from the outside of the first filter 320 and flow into the first filter 320 through the first filter surface.

[0188] The dust filtered by the second filter 700 may accumulate on a second filter surface. The second filter surface may be an outer surface of the second filter 700. The air discharged from the second cyclone unit 400 may flow toward the suction motor 140 after dust is filtered through the second filter surface.

[0189] The air passing through the second filter 700 may flow from the outside to the inside of the second filter 700. The air discharged from the second cyclone unit 400 may start from the outside of the second filter 700 and flow into the second filter 700 through the second filter surface.

[0190] The first cleaning member 610 may sweep the dust accumulated on the first filter surface of the first filter 320, and the second cleaning member 620 may sweep the dust accumulated on the second filter surface of the second filter 700. Since the cleaning members 610 and 620 may directly sweep the dust-accumulated surfaces of the filters 320 and 700, dust can be prevented from accumulating on the filters 320 and 700, thereby improving the performance of the filters 320 and 700.
