Description

vacuum cleaner

[0001] The present invention relates to a vacuum cleaner.

[0002]

[0003] In general, a vacuum cleaner is a home appliance that uses electricity to suck up air and fills a dust bin inside the product with small pieces of trash or dust. It is commonly called a vacuum cleaner.

[0004] These vacuum cleaners can be categorized into manual vacuum cleaners, which the user moves to clean, and automatic vacuum cleaners, which clean by moving around on their own. Manual vacuum cleaners can be categorized by type, including canister vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick vacuum cleaners.

[0005] In the past, canister-type vacuum cleaners were widely used in household vacuum cleaners, but recently, handheld vacuum cleaners and stick vacuum cleaners that provide the dust bin and vacuum cleaner body as an integrated unit, which improves convenience, are being widely used.

[0006] Canister-type vacuum cleaners have a main body and suction inlet connected by a rubber hose or pipe, and in some cases, a brush can be inserted into the suction inlet for use.

[0007] Handheld vacuum cleaners maximize portability. They are lightweight, but their short length limits the cleaning area they can be used in while seated. Therefore, they are used for cleaning small areas, such as desks, sofas, or inside cars.

[0008] Stick vacuums can be used standing up, allowing for cleaning without bending down. This makes them ideal for moving around and cleaning large areas. While handheld vacuums are suitable for cleaning tight spaces, stick vacuums can clean wider areas and reach high, out-of-reach places. Recently, stick vacuums have been offered in modular configurations, allowing users to actively adapt the vacuum to suit a variety of applications.

[0009] Meanwhile, a vacuum cleaner is disclosed in Korean Patent Publication No. 10-2098784.

[0010] The vacuum cleaner of the above prior art patent document may include a filter unit capable of filtering dust from air discharged from a cyclone unit and a movable unit that removes dust from the outer surface of the filter unit while moving in a straight direction.

[0011] However, the above prior art document only discloses a structure for removing dust accumulated on the outer surface of a single filter that filters dust from air drawn in through an intake, and does not disclose a structure for removing dust accumulated on the outer surface of each filter in a vacuum cleaner equipped with a plurality of filters.

[0012] In particular, when multiple filters are arranged inside the main body at the top of the dustbin, there is a problem in that it is difficult for the user to easily separate and clean the filters. That is, when a separate filter is arranged inside the main body in addition to the filter unit disclosed in the above-mentioned prior patent document, the user must separate the dustbin and the second cyclone unit from the main body and then remove the filter from the main body in order to clean the filter arranged inside the main body, which is cumbersome.

[0013]

[0014] The present invention was created to improve the problems described above, and the object of the present invention is to provide a vacuum cleaner that can remove dust accumulated in at least one filter with a simple action of a user pushing or pulling an operating unit.

[0015] In addition, the present invention aims to provide a vacuum cleaner in which the filtration performance of a filter and the suction performance by a suction motor can be improved by directly sweeping the surface where dust accumulates among the outer and inner surfaces of each filter.

[0016] In addition, the present invention aims to provide a vacuum cleaner that can prevent dust stored inside the dust bin from flying out through the open upper side of the dust bin when a user pulls or pushes the operating unit to separate the dust bin from the support unit of the main body housing.

[0017] In addition, the present invention aims to provide a vacuum cleaner in which a second cleaning member is connected to a dust bin and an operating unit is fixed to the dust bin, so that when a user pulls or pushes the operating unit, the dust bin, in which the first cleaning member is disposed, can move more stably.

[0018] In addition, the present invention aims to provide a vacuum cleaner in which the second cleaning member is connected to the operating unit and the operating unit is fixed to the dust bin, so that when a user pulls or pushes the operating unit, the second cleaning member moves without shaking, thereby improving operability.

[0019] In addition, the present invention aims to provide a vacuum cleaner having a structure in which a first cleaning member for sweeping away dust accumulated in a first filter, a second cleaning member for sweeping away dust accumulated in a second filter, and a third cleaning member for sweeping away dust accumulated in a third filter are connected to each other, thereby removing dust accumulated in each filter by only moving an operating unit.

[0020] In addition, the present invention aims to solve the problem of providing a vacuum cleaner in which a second filter and / or a third filter are connected to an operating unit, and the operating unit is disposed in a state separate from a dust bin, so that when a user pulls or pushes only the operating unit, dust accumulated in the second filter and / or the third filter can be removed.

[0083] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0084] The present invention is susceptible to various modifications and embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. This is not intended to limit the invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention.

[0087]

[0088] FIG. 1 is a perspective view of a vacuum cleaner according to a first embodiment of the present invention, FIG. 2 is a cross-sectional view of a vacuum cleaner according to the first embodiment of the present invention, FIG. 3 is a drawing showing a state in which an operating part is pulled out in FIG. 2, FIG. 4 is a drawing showing a state in which a scattering prevention part is removed in FIG. 3, and FIG. 5 is a drawing for explaining a detailed configuration of a first cleaning member and a second cleaning member of a vacuum cleaner according to the first embodiment of the present invention.

[0089] Referring to FIGS. 1 to 5, a vacuum cleaner (1) according to a first embodiment of the present invention will be described as follows.

[0090] A vacuum cleaner (1) may refer to a vacuum cleaner that is manually operated by a user. For example, the vacuum cleaner (1) may refer to a handheld vacuum cleaner or a stick vacuum cleaner.

[0091] Meanwhile, in one embodiment of the present invention, the direction of the cleaner (1) can be defined based on the time when the bottom surface (lower surface) of the battery housing (160) is placed on the ground.

[0092] At this time, the front may refer to the direction in which the suction unit (120) is arranged based on the suction motor (140), and the rear may refer to the direction in which the handle (150) is arranged based on the suction motor (140). In addition, when looking at the suction unit (120) from the suction motor (140), the direction in which it is arranged on the right may be referred to as the right, and the direction in which it is arranged on the left may be referred to as the left. In addition, in one embodiment of the present invention, the upper and lower sides may be defined along the direction perpendicular to the ground when the bottom surface (lower surface) of the battery housing (160) is placed on the ground.

[0093] The vacuum 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), a suction motor (140), a handle (150), and an operating unit (not shown).

[0094] The main body housing (110) may form the exterior of the vacuum cleaner (1). The main body housing (110) may provide a space capable of accommodating a suction motor (140) and a second filter (700) therein. The main body housing (110) may be configured in a shape similar to a cylinder.

[0095] The suction unit (120) may be positioned inside the dustbin (200). For example, the suction unit (120) may be formed in the shape of a pipe with an open interior. The suction unit (120) may be coupled to an extension pipe (not shown). The suction unit (120) may provide a suction path (120a) through which air containing dust may flow.

[0096] The suction unit (120) can be coupled to the second cyclone unit (400). The suction unit (120) can be coupled to the case (310) of the second cyclone unit (400) to be described later.

[0097] At least a portion of the suction unit (120) may be arranged inside the second cyclone unit (400). Specifically, at least a portion of the suction unit (120) may be arranged to be surrounded by a plurality of cyclone bodies (410). Accordingly, at least a portion of the suction unit (120) may extend in the same direction as or parallel to the direction in which the suction motor axis (a1) extends.

[0098] The suction part (120) may be formed in a folded shape. One end of the suction part (120) may be formed to penetrate the cover body (221) of the discharge cover (220). The other end of the suction part (120) may be formed to penetrate the outer surface of the second cyclone part (400) (the outer surface of the case (310) or the first filter (320). Accordingly, air sucked from the outside through the suction part (120) may flow through the suction path (120a) and be discharged into the dust bin (200).

[0099] A vacuum cleaner (1) according to an embodiment of the present invention may include at least one cyclone unit capable of separating dust by cyclone flow. For example, the vacuum cleaner (1) may include a first cyclone unit (130) and a second cyclone unit (400).

[0100] The first cyclone section (130) is a configuration that applies the principle of a dust collector that uses centrifugal force to separate dust sucked into the interior of the main body (100) through the suction section (120). That is, the first cyclone section (130) refers to a space in which a cyclone flow that rotates along the inner surface of the dust bin (200) occurs, and the first cyclone section (130) may refer to a portion of the space inside the dust bin (200).

[0101] The first cyclone unit (130) can be communicated with the suction unit (120). The first cyclone unit (130) can separate dust sucked into the interior through the suction unit (120). The space inside the first cyclone unit (130) can be communicated with the space inside the dust bin (200).

[0102] The cyclone flow generated in the first cyclone section (130) may be due to the suction force of the suction motor (140).

[0103] The cyclone flow generated in the first cyclone section (130) can be formed between the inner surface of the dustbin (200) and the outer surface of the case (310) described later. That is, the cyclone flow can be formed inside the first cyclone section (130).

[0104] The space inside the first cyclone section (130) can be communicated with the suction section (120). Air and dust sucked through the suction section (120) flow along the inner surface of the first cyclone section (130), thereby generating a cyclone flow in the inner space of the first cyclone section (130).

[0105] For example, the cyclone flow generated in the first cyclone section (130) may be formed to surround the inner circumference of the dustbin (200) in a circular shape. The air sucked in through the suction section (120) flows in a circular shape along the inner circumference of the dustbin (200) based on the central axis (a2) of the dustbin, thereby allowing a cyclone flow to occur in the inner space of the first cyclone section (130).

[0106] Specifically, when the axis (a3) ​​of the cyclone flow generated in the first cyclone unit (130) is arranged vertically downward in the direction of gravity, the air sucked through the suction unit (120) can flow in a circular shape along the inner surface of the dustbin (200) based on the central axis (a2) of the dustbin. Alternatively, when the axis (a3) ​​of the cyclone flow generated in the first cyclone unit (130) is arranged parallel to the ground, the air sucked through the suction unit (120) can flow in a circular shape along the inner surface of the dustbin (200) based on the central axis (a2) of the dustbin.

[0107] As another example, the cyclone flow generated in the first cyclone section (130) may be formed in a spiral shape along the inner circumference of the dustbin (200). That is, the air sucked in through the suction section (120) flows in a spiral shape along the inner circumference of the dustbin (200), thereby generating a cyclone flow in the internal space of the first cyclone section (130).

[0108] Specifically, when the axis (a3) ​​of the cyclone flow generated in the first cyclone section (130) is arranged to be inclined with respect to the ground, the air sucked through the suction section (120) can flow in a spiral shape along the inner circumference of the dust bin (200).

[0109] The vacuum cleaner (1) according to an embodiment of the present invention may include a second cyclone unit (400) that separates dust again from the air discharged from the first cyclone unit (130). That is, the second cyclone unit (400) can filter out small dust particles that the first cyclone unit (130) and the first filter unit (300) could not filter out from the air that passed through the first cyclone unit (130) and the first filter unit (300).

[0110] At this time, the second cyclone unit (400) may be positioned inside the first cyclone unit (130) so as to minimize the size of the vacuum cleaner (1). The second cyclone unit (400) may be positioned below the suction motor (140). Specifically, the second cyclone unit (400) may be positioned inside the first filter unit (300). That is, the first cyclone unit (130) and the second cyclone unit (400) may be positioned inside the dust bin (200) with the first filter unit (300) interposed therebetween.

[0111] The second cyclone unit (400) may include a plurality of cyclone bodies (410) arranged in parallel. Accordingly, the air discharged from the first cyclone unit (130) may pass through the first filter unit (300) and be divided and passed through the plurality of cyclone bodies (410). That is, the cyclone flow generated in the second cyclone unit (400) may be formed inside the cyclone body (410).

[0112] Meanwhile, the second cyclone section (400) may also include a single cyclone body (410), and in this case, the axis (a3) ​​of the cyclone flow generated in the second cyclone section (400) may extend in the vertical direction.

[0113] In addition, the axis (a3) ​​of the cyclone flow generated in the first cyclone section (130) may also extend in the vertical direction. Accordingly, the axis (a3) ​​of the cyclone flow generated in the first cyclone section (130) and the axis (a3) ​​of the cyclone flow generated in the second cyclone section (400) may form a coaxial line in the vertical direction or may be formed in parallel.

[0114] A storage member (311) for storing dust separated from the second cyclone unit (400) may be placed inside the dust bin (200). The storage member (311) may be connected to the lower side of the case (310) and may be in contact with the upper surface of the discharge cover (220). In addition, the lower side of the storage member (311) may be open.

[0115] The storage member (311) can divide the space inside the dust bin (200) into a first dust storage unit (311a) where dust separated from the first cyclone unit (130) is stored, and a second dust storage unit (311b) where dust separated from the second cyclone unit (400) is stored.

[0116] Accordingly, the space between the storage member (311) and the dust bin (200) can be defined as the first dust storage unit (311a), and the lower internal space of the storage member (311) can be defined as the second dust storage unit (311b).

[0117] The discharge cover (220) can open and close the first dust storage unit and the second dust storage unit together. That is, the first dust storage unit and the second dust storage unit can be exposed together to the outside.

[0118] The suction motor (140) can generate a suction airflow that sucks in air. The suction motor (140) can be accommodated within the main body housing (110).

[0119] The suction motor (140) can generate suction force by rotation. For example, the suction motor (140) can be provided in a shape similar to a cylinder.

[0120] At this time, cyclone flow may be generated by the suction force of the suction motor (140).

[0121] Specifically, when the suction motor (140) is operated, the air sucked through the suction unit (120) by the suction force of the suction motor (140) can generate a cyclone flow in the first cyclone unit (130) and / or the second cyclone unit (400).

[0122] The present invention may include a virtual suction motor axis (a1) extending from the rotation axis of the suction motor (140). The suction motor axis (a1) may be arranged coaxially or parallel to the dustbin central axis (a2), the cyclone flow axis (a3), and the case central axis (a4).

[0123] The suction motor (140) may be located inside the main body housing (110). And, at least a portion of the suction motor (140) may be located above the second cyclone unit (400). Accordingly, the suction motor (140) may be located above the dust bin (200).

[0124] The suction motor (140) can be connected to the outlet of the second cyclone section (400).

[0125] The axis (a3) ​​of the cyclone flow of the first cyclone section (130) can pass through the suction motor (140).

[0126] In an embodiment of the present invention, when the suction motor (140) is positioned above the second cyclone section (400), the air discharged from the second cyclone section (400) can flow directly toward the suction motor (140), so that the flow path between the second cyclone section (400) and the suction motor (140) can be minimized.

[0127] An air outlet (110a) for discharging air sucked in by the suction force of the suction motor (140) may be formed in the main body housing (110).

[0128] A flow guide may be arranged in the main body housing (110). The flow guide may guide the flow of air discharged through the air outlet (110a).

[0129] The handle (150) can be gripped by the user. For example, the handle (150) may be formed in a shape similar to a cylinder. Alternatively, the handle (150) may be formed in a curved cylinder shape. The handle (150) may be positioned at a predetermined angle with respect to the main body housing (110), the suction motor (140), or the first cyclone unit (130).

[0130] The handle (150) may include a grip portion formed in a pillar shape so that a user can grip it, a first extension portion connected to one longitudinal (axial) end of the grip portion and extending toward the suction motor (140), and a second extension portion connected to the other longitudinal (axial) end of the grip portion and extending toward the dust bin (200).

[0131] Meanwhile, in this embodiment, a virtual gripping portion penetration line can be formed by extending along the longitudinal direction of the gripping portion (axial direction of the column) and penetrating the gripping portion.

[0132] For example, the grip portion penetration line may be a virtual line formed inside a cylindrical handle (150), and may be a virtual line formed parallel to at least a portion of the outer surface (outer circumference) of the grip portion.

[0133] The upper surface of the handle (150) may form a portion of the appearance of the upper surface of the vacuum cleaner (1). This prevents the components of the vacuum cleaner (1) from coming into contact with the user's arm when the user holds the handle (150).

[0134] The first extension portion 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 portion may extend in a horizontal direction.

[0135] The second extension may extend from the phasing portion toward the dust bin (200). At least a portion of the second extension may extend horizontally.

[0136] The control unit (not shown) may be positioned on the main body housing (110). The control unit (not shown) may be positioned on the outer surface of the main body housing (110). The control unit (not shown) may be composed of a plurality of buttons, and when a user presses a corresponding button, a corresponding command may be executed. The user may input an operation or stop command for the vacuum cleaner (1) through the control unit (not shown).

[0137] The vacuum cleaner (1) may include a dust bin (200). The dust bin (200) may be connected to a suction unit (120). A first cyclone unit (130) may be located inside the dust bin (200). The dust bin (200) may store dust separated from the first cyclone unit (130).

[0138] The dustbin (200) may include a dustbin body (210), a discharge cover (220), a dustbin compression lever (not shown), and a compressor (not shown).

[0139] The dustbin body (210) can provide a space for storing dust separated from the first cyclone unit (130). For example, the dustbin body (210) can be formed in a shape similar to a cylinder.

[0140] Meanwhile, in the present embodiment, a virtual dustbin central axis (a2) may be formed by penetrating the interior (internal space) of the dustbin body (210) and extending along the longitudinal direction of the dustbin body (210) (meaning the axial direction in the cylindrical dustbin body (210)).

[0141] The lower surface (bottom surface) of the dustbin body (210) may be partially open. In addition, a lower extension (not shown) may be formed on the lower surface (bottom surface) of the dustbin body (210). The lower extension may be formed to block a portion of the lower surface of the dustbin body (210).

[0142] The dustbin (200) may include a discharge cover (220). The discharge cover (220) may be placed on the lower surface of the dustbin (200).

[0143] The discharge cover (220) may be provided to open and close one end in the longitudinal direction of the dustbin body (210). Specifically, the discharge cover (220) may selectively open and close the lower part of the dustbin (200) that opens downward.

[0144] The discharge cover (220) may include a cover body (221) and a hinge part (222). The cover body (221) may be formed to block a portion of the lower surface of the dustbin body (210). The cover body (221) may rotate downward based on the hinge part (222). The hinge part (222) may be arranged adjacent to the battery housing (160). A torsion spring may be provided in the hinge part (222). Therefore, when the discharge cover (220) is separated from the dustbin body (210), the cover body (221) may be supported in a state in which it is rotated by a predetermined angle or more about the hinge part (222) as an axis in the dustbin body (210) by the elastic force of the torsion spring.

[0145] The discharge cover (220) can be coupled to the dust bin (200) through a hook connection. Meanwhile, the discharge cover (220) can be separated from the dust bin (200) through a coupling lever (not shown). The coupling lever (not shown) can be arranged at the front of the dust bin (200). Specifically, the coupling lever (not shown) can be arranged on the outer surface of the front side of the dust bin (200). When an external force is applied, the coupling lever (not shown) can elastically deform a hook extended from the cover body (221) to release the hook connection between the cover body (221) and the dust bin body (210).

[0146] When the discharge cover (220) is closed, the lower surface of the dust bin (200) may be blocked (sealed) by the discharge cover (220) and the lower extension.

[0147] The dustbin (200) may include a dustbin compression lever. The dustbin compression lever may be disposed outside the dustbin (200). The dustbin compression lever may be disposed outside the dustbin (200) to move up and down. The dustbin compression lever may be connected to a compressor (not shown). When the dustbin compression lever moves downward due to an external force, the compressor (not shown) may also move downward. This may provide convenience to the user. The compressor (not shown) and the dustbin compression lever may return to their original positions by an elastic member (not shown). Specifically, when the external force applied to the dustbin compression lever is removed, the elastic member may move the dustbin compression lever and the compressor (not shown) upward.

[0148] A compressor (not shown) may be placed inside the dustbin body (210). The compressor may move within the internal space of the dustbin body (210). Specifically, the compressor may move up and down within the dustbin body (210). Through this, the compressor may compress dust within the dustbin body (210) downward. In addition, when the discharge cover (220) is separated from the dustbin body (210) and the lower portion of the dustbin (200) is opened, the compressor may move from the upper portion to the lower portion of the dustbin (200) to remove foreign substances such as residual dust within the dustbin (200). Through this, the suction power of the vacuum cleaner may be improved by preventing residual dust from remaining within the dustbin (200). In addition, by preventing residual dust from remaining within the dustbin (200), an unpleasant odor caused by the residual dust may be eliminated.

[0149] The vacuum cleaner (1) may include a battery housing (160). The battery housing (160) may accommodate a battery (161). The battery housing (160) may be positioned at the lower side of the handle (150). For example, the battery housing (160) may have a hexahedral shape with an open lower side. The upper surface of the battery housing (160) may be connected to the handle (150).

[0150] The battery housing (160) may include a receiving portion that opens downward. The battery (161) may be removed through the receiving portion of the battery housing (160).

[0151] The battery housing (160) may be provided with battery terminals exposed to the outside.

[0152] When the battery terminal of the battery housing (160) and the external charging terminal (not shown) are combined, power can be supplied to the battery (161) through the battery terminal. The battery terminal can be arranged spaced apart from each other on the lower surface of the battery housing (160).

[0153] The vacuum cleaner (1) may include a battery (161).

[0154] For example, the battery (161) may be detachably coupled to the vacuum cleaner (1). The battery (161) may be detachably coupled to the battery housing (160). For example, the battery (161) may be inserted into the interior of the battery housing (160) from the lower portion of the battery housing (160). With such a configuration, the portability of the vacuum cleaner (1) may be improved.

[0155] In contrast, the battery (161) may be integrally provided inside the battery housing (160). In this case, the lower surface of the battery (161) is not exposed to the outside.

[0156] The battery (161) stores electric energy and can supply power to each component including the suction motor (140) of the vacuum cleaner (1). The battery (161) may be placed at the bottom of the handle (150). The battery (161) may be placed at the bottom of the dustbin (200). That is, the suction motor (140) and the battery (161) may be placed so as not to overlap in the front-back direction, and may also be placed at different heights. With respect to the handle (150), the suction motor (140), which is heavier, is placed at the top of the handle (150), and the battery (161), which is lighter, is placed at the bottom of the handle (150), so that the weight of the entire vacuum cleaner (1) can be evenly distributed. This can prevent the user's wrist from being strained when the user holds the handle (150) and cleans.

[0157] In an 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. When the vacuum cleaner (1) is placed on the floor, the battery (161) may be placed on the floor, so that the battery (161) can 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 the external air of the battery (161), the cooling performance of the battery (161) may be improved.

[0158] Meanwhile, when the battery (161) is integrally fixed to the battery housing (160), the structure for attaching and detaching the battery (161) and the battery housing (160) can be reduced, so the overall size of the vacuum cleaner (1) can be reduced and its weight can be reduced.

[0159] The vacuum cleaner (1) may include an extension pipe (not shown). The extension pipe (not shown) may be connected to a cleaning module (not shown). The extension pipe (not shown) may be connected to the main body (100). The extension pipe (not shown) may be connected to a suction unit (120) of the main body (100). The extension pipe (not shown) may be formed in a long cylindrical shape.

[0160] The main body (100) can be connected to an extension pipe (not shown). The main body (100) can be connected to a cleaning module through the extension pipe (not shown). The main body (100) can generate suction force through a suction motor (140) and provide suction force to the cleaning module through the extension pipe (not shown). External dust can be introduced into the main body (100) through the cleaning module and the extension pipe (not shown).

[0161] The vacuum cleaner (1) may include a cleaning module (not shown). The cleaning module (not shown) may be connected to an extension tube (not shown). Accordingly, external air may be drawn into the main body (100) of the vacuum cleaner (1) through the cleaning module (not shown) and the extension tube (not shown) by the suction force generated in the main body (100) of the vacuum cleaner (1).

[0162] The vacuum cleaner (1) may include a first filter unit (300). The first filter unit (300) may filter 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).

[0163] The first filter unit (300) may include a case (310) and a first filter (320).

[0164] The case (310) can be placed inside the dustbin (200). The case (310) can be placed inside the first cyclone unit (130).

[0165] A space may be formed inside the case (310). A second cyclone unit (400) may be placed inside the case (310).

[0166] The case (310) may be formed in a cylindrical shape, although this is not limited to the shape.

[0167] The case central axis (a4) can extend in the vertical direction. The case central axis (a4) can extend along the longitudinal direction of the case (310).

[0168] For example, the case central axis (a4) may be formed coaxially with the axis (a3) ​​of the cyclone flow generated in the first cyclone section (130). As another example, the case central axis (a4) may be formed parallel to the axis (a3) ​​of the cyclone flow generated in the first cyclone section (130). As yet another example, the case central axis (a4) of the case (310) may be formed coaxially with the suction motor axis (a1).

[0169] The first filter (320) can filter out dust from the air discharged from the first cyclone section (130).

[0170] 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) can be filtered by the first filter (320).

[0171] The first filter (320) may be placed in the case (310). Alternatively, the first filter (320) may refer to a portion of the case (310). Alternatively, the lower edge of the first filter (320) may be coupled to the case (310).

[0172] Air passing through the first filter (320) can be introduced into the second cyclone section (400) placed inside the case (310).

[0173] At this time, the outer side and / or outside of the case (310) may mean the direction facing the first cyclone unit (130) based on the case (310), and the inner side and / or inside of the case (310) may mean the direction facing the second cyclone unit (400) based on the case (310).

[0174]

[0175] A vacuum cleaner according to an embodiment of the present invention may include a second cyclone unit (400).

[0176] The second cyclone unit (400) may be arranged at least partially inside the first cyclone unit (130) and may separate dust from the air discharged from the first cyclone unit (130). After the 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 the flow path.

[0177] The second cyclone section (400) may be formed by a set of axial cyclones formed to separate dust from air flowing in the axial direction.

[0178] The second cyclone section (400) may include a cyclone body (410), a vortex finder (420), and a band member (430).

[0179] The cyclone body (410) is a structure that applies the principle of a dust collector that uses centrifugal force to separate dust from air that has passed through the first filter unit (300). Specifically, the cyclone body (410) can separate dust from air that has passed through the first filter (320) by using cyclone flow. Since a space through which air can flow can be formed inside the cyclone body (410), air that has passed through the first filter (320) can be introduced into the inside of the cyclone body (410).

[0180] The cyclone body (410) may be placed inside the case (310). Specifically, at least a portion of the cyclone body (410) may be placed inside the case (310), and air passing through the first filter (320) may be introduced into the inside of the cyclone body (410).

[0181] A plurality of cyclone bodies (410) may be provided. Each cyclone body (410) may be formed with an inlet forming an outer wall around the hollow portion. The outer walls around the hollow portion formed by the cyclone bodies (410) may correspond to the outer walls of each axial cyclone. Air discharged from the first cyclone section (130) may be introduced into the cyclone body (410) through the inlet. Air circulating along the inner surface of the cyclone body (410) may form a cyclone flow.

[0182] Dust, which is heavier than air, can rotate within a vortex with a larger rotation radius than air. Since the dust rotates inside the cyclone body (410), the maximum rotation radius of the dust can be defined by the cyclone body (410).

[0183] The lower part of the cyclone body (410) may have a slanted shape that becomes narrower as it goes down. The lower part of the cyclone body (410) has a shape that becomes narrower as it goes down to induce the falling of dust separated from the air and prevent the dust from being discharged along the air to the vortex finder (420).

[0184] An exhaust port may be formed at the bottom 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 exhaust port. In addition, the bottom of the cyclone body (410) may be communicated with the internal space of the storage member (311). Therefore, dust rotating along the vortex inside the cyclone body (410) may fall and be stored in the storage member (311). The dust stored in the storage member (311) may be communicated with the external space when the exhaust cover (220) is opened.

[0185] The upper portion of the cyclone body (410) may be formed to accommodate a 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 distinguished based on the position where the inner diameter narrows.

[0186] The outer surface of each cyclone body (410) is connected to be in contact with the surrounding cyclone bodies (410), so that a plurality of cyclone bodies (410) may form a single member. It is preferable that the cross-section of each cyclone body (410) 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, even if the outer surfaces of adjacent cyclone bodies (410) are in close contact with each other, a flow path for air and dust can be formed between them. If a flow path for 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.

[0187] It is not excluded that the cross-section of each cyclone body (410) may be formed as a polygon. However, even if the cross-section of each cyclone body (410) is formed as a polygon, it is preferable that it be formed as a polygon in which a path for air and dust can be formed.

[0188] The vortex finder (420) is configured to discharge air that has passed through the cyclone flow from the inside of the cyclone body (410).

[0189] A path through which air can flow may be formed inside the vortex finder (420). A plurality of vortex finders (420) may be provided, and at least a portion of each vortex finder (420) may be disposed inside each cyclone body (410). The outer surface of each vortex finder (420) may be spaced apart from the inner surface of each cyclone body (410). Each vortex finder (420) has an inlet forming an outer wall around the hollow portion, and air passing through the cyclone body (410) may be discharged through the inlet of each vortex finder (420). In addition, air introduced into the inlet of the vortex finder (420) may flow upward and be discharged through the outlet of the vortex finder (420).

[0190] The lower portion of the vortex finder (420) may have a higher height than the band member (430). However, the upper portion of the vortex finder (420) may have the same height as the band member (430). The lower portion of the vortex finder (420) may protrude below the band member (430), but the upper portion may not.

[0191] It is preferable that the cross-section of each vortex finder (420) has a circular ring shape. It is not excluded that the cross-section of each vortex finder (420) is formed into a polygon. However, even if the cross-section of each vortex finder (420) is formed into a polygon, it is preferable that it be formed into a polygon that can form a path for air and dust.

[0192] The band member (430) may be formed to surround the outer surface of the vortex finder (420). At this time, the band member (430) may be named by other names as needed. For example, names such as a ring portion, a ring portion, a border 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.

[0193] The band member (430) may be mounted on the first filter (320) and may have a shape corresponding to the upper portion of the first filter (320). The 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 that surrounds the vortex finder (420). However, this does not exclude the possibility that the upper portion of the first filter (320) and the band member (430) may be formed in a polygonal shape.

[0194] The guide vane (not shown) is configured to guide air discharged from the first cyclone section (130) toward the inside of the cyclone body (410). The guide vane (not shown) can form a flow path through which air introduced through the inlet can flow toward the inside of the cyclone body (410). Therefore, air flowing along the flow path formed by the guide vane (not shown) can form a swirling flow between the vortex finder (420) and the cyclone body (410).

[0195] At least a portion of the guide vane (not shown) may be positioned between the cyclone body (410) and the vortex finder (420) and may be connected to each cyclone body (410) and each vortex finder (420). One end of the guide vane (not shown) may be connected to the outer surface of the vortex finder (420) along a spiral direction, and the other end of the guide vane (not shown) may be connected to the inner surface of the cyclone body (410) along a spiral direction.

[0196] Each cyclone body (410) and each vortex finder (420) may be provided with a plurality of guide vanes (not shown), and the guide vanes (not shown) may extend in a spiral direction to generate a swirling flow. As the guide vanes (not shown) extend in a spiral direction, air and dust introduced into the inlet of the cyclone body (410) may form a swirling flow.

[0197] Below, the flow of air flowing through the path of the vacuum cleaner (1) according to an embodiment of the present invention will be described.

[0198] First, when the suction motor (140) is operated, external air can be drawn into the dust bin (200) through the suction unit (120).

[0199] The air separated from dust by the first cyclone unit (130) inside the dust bin (200) can be introduced into the cyclone body (410) after passing through the first filter (320). The air introduced into the cyclone body (410) can fall while forming a swirling flow and then flow upwards to pass through the vortex finder (420). The air that has passed through the vortex finder (420) can have dust filtered in the second filter (700) arranged above the second cyclone unit (400). The air that has dust filtered in the second filter (700) can flow toward the suction motor (140) arranged downstream of the suction airflow. The air that has passed through the suction motor (140) can be discharged to the outside through the air outlet (110a) after passing through the third filter (800).

[0200]

[0201] A vacuum cleaner (1) according to a first embodiment of the present invention may include a main body (100), a dust bin (200), a suction unit (120), a first filter (320), a second filter (700), an operating unit (500), a first cleaning member (610), and a second cleaning member (620).

[0202] The first filter (320) may be placed inside the dust bin (200) and may filter out dust from air drawn in through the suction unit (120). External air drawn in through the suction unit (120) is drawn into the first cyclone unit (130), and air discharged from the first cyclone unit (130) may have dust filtered while passing through the first filter (320). The first filter (320) may be a pre-filter.

[0203] The first filter (320) may be formed to surround the second cyclone section (400) while being spaced apart from the second cyclone section (400). For example, the first filter (320) may be formed in a shape similar to a cylinder with an open interior.

[0204] The second filter (700) can be placed inside the main body housing (110) and can filter out dust from air passing through the first filter (320). Air passing through the first filter (320) is introduced into the second cyclone unit (400), and air discharged from the second cyclone unit (400) can have dust filtered while passing through the second filter (700).

[0205] The second filter (700) can be formed in a shape similar to a cylinder with an open interior.

[0206] The operating unit (500) is positioned on the outside of the dustbin (200) and can move together with the dustbin (200). The operating unit (500) can be formed in a ring shape so that a user can grasp it. When a user grasps the operating unit (500) and pulls it outward, the dustbin (200) to which the operating unit (500) is fixed moves outward.

[0207] The first cleaning member (610) is placed inside the dust bin (200), and can sweep the first filter (320) when the operating unit (500) moves. The first cleaning member (610) may be a brush including a plurality of bristles.

[0208] The first cleaning member (610) can be moved together with the dust bin (200) while being fixed inside the dust bin (200). The first cleaning member (610) can be moved in a straight line along the length direction of the first filter (320). The inner diameter of the first cleaning member (610) can be formed to correspond to the outer diameter of the first filter (320). Therefore, when the user holds the operating unit (500) and pulls it outward or pushes it inward, the first cleaning member (610) can be moved in a straight line together with the dust bin (200). In addition, as the first cleaning member (610) moves, it can sweep away dust accumulated on the first filter surface, which is the outer surface of the first filter (320).

[0209] The second cleaning member (620) can sweep the second filter (700) when the operating unit (500) moves.

[0210] The second cleaning member (620) can be connected to the dust bin (200). Specifically, the transmission unit (900) can connect the second cleaning member (620) and the dust bin (200). Therefore, this structure has the advantage of allowing the dust bin (200) to move more stably when the user pulls or pushes the operating unit (500).

[0211] The transmission unit (900) may extend along the length direction of the second filter (700). The transmission unit (900) may extend along the suction motor axis (a1).

[0212] The second cleaning member (620) may include a moving member (621) and a brush (622).

[0213] The moving part (621) can be formed in a shape similar to a cylinder with an open interior.

[0214] The moving part (621) can move along the 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).

[0215] The moving part (621) can be connected to the dust bin (200) by the transmission part (900). The transmission part (900) can be arranged parallel to the suction motor axis (a1).

[0216] The brush (622) may be arranged on the inner surface of the moving part (621). The brush (622) may include a plurality of bristles. The brush (622) may be arranged to contact the second filter (700).

[0217] Dust filtered by the first filter (320) may accumulate on the first filter surface. The first filter surface may refer to the outer surface of the first filter (320).

[0267] The third cleaning member (2630) may include a moving member (2631) and a brush (2632).

[0268] The moving part (2631) may be formed in a shape similar to a cylinder with an open interior. The moving part (2631) may move along the space between the outer side of the suction motor (140) and the inner side of the third filter (800).

[0269] The brush (2632) may be arranged on the outer surface of the moving part (2631). The brush (2632) may include a plurality of bristles. The brush (2632) may be arranged to contact the third filter (800).

[0270] The third cleaning member (2630) may be connected to the second cleaning member (2620). Specifically, a connecting portion (2640) may connect the moving portion (2631) of the third cleaning member (2630) and the moving portion (2621) of the second cleaning member (2620). The connecting portion (2640) may be arranged parallel to the suction motor axis (a1).

[0271] When a user grasps and pushes or pulls the operating unit (500), the dust bin (200) connected to the operating unit (500) moves along the suction motor axis (a1), and the first cleaning member (2610) arranged inside the dust bin (200) can sweep away dust accumulated on the first filter surface of the first filter (320). At the same time, the moving member (2621) of the second cleaning member (2620) moves along the longitudinal direction of the second filter (700), and the brush (2622) arranged along the inner circumference of the moving member (2621) can sweep away dust accumulated on the second filter surface of the second filter (700). At the same time, the moving part (2631) of the third cleaning member (2630) moves along the longitudinal direction of the third filter (800), and the brush (2632) arranged along the outer circumference of the moving part (2631) can sweep away dust accumulated on the third filter surface of the third filter (800).

[0272] The cleaner (3) according to the third embodiment of the present invention may further include a guide body (2930) and an elastic member (2940).

[0273] The guide body (2930) may be positioned inside the main body housing (110). The guide body (2930) may provide a space for the second transmission member (2920) to move. Accordingly, the second transmission member (2920) may be positioned to penetrate the space formed in the guide body (2930). In addition, the second transmission member (2920) may move in a straight line through the space formed through the guide body (2930).

[0276] When the operating part (500) moves in a direction in which the dustbin (200) is separated from the main body (100), the elastic member (2940) can be compressed. In addition, when the elastic member (2940) is elastically restored, the dustbin (200) can move in a direction in which it is coupled to the main body (100) (the direction in which it is inserted).

[0277] Unlike the cleaner (1) according to the first embodiment of the present invention and the cleaner (2) according to the second embodiment, the cleaner (3) according to the third embodiment of the present invention has a difference in that it can sweep away all dust accumulated in the first filter (320), the second filter (700), and the third filter (800).

[0278] Therefore, the cleaner (3) according to the third embodiment of the present invention has the advantage that even if it is equipped with a third filter (800) in addition to the first filter (320) and the second filter (700), the user can clean all the filters with just one action of pushing or pulling the operating unit (500).

[0283] Meanwhile, except for the contents specifically described in the fourth embodiment of the present invention, the cleaner (4) according to the fourth embodiment of the present invention has the same configuration and effects as the cleaner (1) according to the first embodiment of the present invention. Therefore, to avoid redundant description, the cleaner (4) according to the fourth embodiment of the present invention can use the contents of the cleaner (1) according to the first embodiment of the present invention for other configurations, except for those specifically mentioned.

[0284] In addition, in order to avoid duplicate explanation, except where specifically mentioned, the second cleaning member (3620) and the third cleaning member (3630) of the cleaner (4) according to the fourth embodiment of the present invention may use the contents of the second cleaning member (2620) and the third cleaning member (2630) of the cleaner (3) according to the third embodiment.

[0285] The second cleaning member (3620) can sweep the second filter (700) when the operating unit (500) moves.

[0286] The third cleaning member (3630) is connected to the second cleaning member (3620), and when the operating unit (500) moves, the third filter (800) can be swept away.

[0287] To avoid redundant explanation, the third filter (800) according to the fourth embodiment of the present invention may use the contents of the third filter (800) according to the third embodiment.

[0288] The transmission unit (3900) can connect the second cleaning member (3620) and the operating unit (500). The operating unit (500) can be fixed to one end of the transmission unit (3900), and the second cleaning member (3620) can be fixed to the other end of the transmission unit (3900). Accordingly, the operation unit (500) and the second cleaning member (3620) can move in a straight direction together with the transmission unit (3900).

[0289] The transmission unit (3900) may be arranged at least partially inside the main body housing (110). The transmission unit (3900) may be arranged in a direction parallel to the suction motor axis (a1).

[0290] One end of the transmission unit (3900) may be connected to the moving unit (3621) of the second cleaning member (3620), and the other end may be connected to the operating unit (500). The operating unit (500) may be fixed to the outside of the dust bin (200) and may move together with the dust bin (200).

[0291] When the operating unit (500) is moved, the moving unit (3621) connected to the operating unit (500) can move along the length direction of the second filter (700), and at the same time, the brush (3622) arranged along the inner circumference of the moving unit (3621) can sweep away dust accumulated on the second filter surface of the second filter (700).

[0292] The main body (100) may include a guide body (3910).

[0293] Specifically, the guide body (3910) may be positioned inside the main housing (110). The guide body (3910) may provide a space for the transmission unit (3900) to move. Accordingly, the transmission unit (3900) may be positioned to penetrate the space formed in the guide body (3910). In addition, the transmission unit (3900) may move in a straight line through the space formed through the guide body (3910).

[0294] The cleaner (4) according to the fourth embodiment of the present invention may further include an elastic member (3940).

[0295] The elastic member (3940) can be wound around the transmission member (3900). One end of the elastic member (3940) can be connected to the second cleaning member (3620), and the other end can be connected to the guide body (3910).

[0296] When the operating unit (500) moves away from the dust bin (200), the elastic member (3940) can be compressed. In addition, when the elastic member (3940) is elastically restored, the operating unit (500) can move toward the dust bin (200).

[0297] Unlike the cleaners (1, 2, 3) according to the first to third embodiments in which the operating unit (500) is fixed to the dust bin (200) and thus the dust bin (200) moves together when the operating unit (500) is moved, the cleaner (4) according to the fourth embodiment of the present invention has a difference in that the dust bin (200) and the operating unit (500) are separated, so that the dust bin (200) remains fixed even when the user pushes or pulls the operating unit (500). In addition, unlike the cleaners (1, 2, 3) according to the first to third embodiments in which the user must push the operating unit (500) downward while holding the handle (150) so that each cleaning member sweeps the filter, the cleaner (4) according to the fourth embodiment of the present invention has a difference in that the user must pull the operating unit (500) upward while holding the handle (150) so that each cleaning member sweeps the filter.

[0298] Accordingly, the cleaner (4) according to the fourth embodiment of the present invention has the advantage that the user can clean the second filter (700) and the third filter (800) with less force since only the operating part (500) separated from the dust bin (200) needs to be moved.
