Description

Technical Field

[0001] This invention relates to vacuum cleaners. Background Technology

[0002] Generally, a vacuum cleaner is a household appliance that uses electricity to suck up small pieces of trash or dust and fills them into a dustbin inside the product; it is usually called a vacuum cleaner.

[0003] Vacuum cleaners can be categorized into manual vacuum cleaners, where the user moves the vacuum cleaner directly to perform cleaning, and automatic vacuum cleaners, which move autonomously to perform cleaning. Manual vacuum cleaners can be further classified according to their shape, such as canister-type vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick-type vacuum cleaners.

[0004] Previously, most household vacuum cleaners were canister vacuums, but in recent years, handheld and stick vacuums have become increasingly popular, combining the dustbin and the vacuum cleaner body into one unit for improved ease of use.

[0005] In a canister vacuum cleaner, a rubber hose or pipe is used to connect the main body and the suction port. A brush can be attached to the suction port for use as needed.

[0006] Handheld vacuum cleaners maximize portability. While lightweight, their short length requires squatting to clean, limiting the cleaning area. Therefore, they are best suited for cleaning specific areas such as desks, sofas, or car interiors.

[0007] Stick vacuum cleaners can be used standing up, allowing cleaning without bending over. This makes them ideal for moving and cleaning in spacious areas. Compared to handheld vacuum cleaners, which are designed for confined spaces, stick vacuum cleaners can clean much wider areas and reach high places that are inaccessible by hand. In recent years, stick vacuum cleaners have been offered in modular form, allowing for proactive changes in vacuum cleaner type and usage for a variety of objects.

[0008] On the other hand, International Patent Publication No. 2023-089298 discloses a dust separator.

[0009] The dust separator according to the aforementioned existing literature includes: a first filter that separates dust from air flowing in through an air inlet; a second filter that further separates dust from air that has passed through the first filter; and a scraper that, by moving in the up-down direction, directly removes dust accumulated in the first filter while indirectly shaking off dust accumulated in the second filter.

[0010] In the dust separator described in the existing literature, when the suction motor is running, air passes from the outer surface of the first filter to the inner surface, and the air that has passed through the first filter passes from the inner surface of the second filter to the outer surface. Therefore, it is a structure in which dust accumulates on the outer surface of the first filter and the inner surface of the second filter.

[0011] Therefore, the dust separator in the aforementioned existing literature can directly clean the dust accumulated on the outer surface of the first filter by moving the scraper up and down, while at the same time shaking off the dust accumulated on the inner surface of the second filter by tapping the outer surface of the second filter with the protrusion connected to the scraper.

[0012] However, according to the aforementioned existing literature, although dust accumulated in the first filter can be directly removed by moving the scraper, there is a limitation in efficiency in removing dust accumulated in the second filter. Therefore, there is a problem of reduced suction performance of the dust separator when dust accumulated in the second filter is not removed. Summary of the Invention

[0013] The problem to be solved

[0014] The present invention is proposed to solve the problems described above, and its object is to provide a vacuum cleaner that can remove dust accumulated in at least one filter by simply pushing and pulling the operating lever by the user.

[0015] In addition, the present invention aims to provide a vacuum cleaner that can directly clean the dust-accumulated surfaces on the outer and inner surfaces of each filter, thereby improving the filtration performance of the filter and the suction performance based on the suction motor.

[0016] In addition, the present invention aims to provide a vacuum cleaner that minimizes the distance between the cleaning unit that removes dust accumulated in the first and second filters and the operating lever that moves the cleaning unit, thereby minimizing the force required for the user to move the operating lever.

[0017] In addition, the present invention aims to provide a vacuum cleaner whose overall center of gravity is as close as possible to the handle held by the user, thereby enabling the user to move the vacuum cleaner with minimal force.

[0018] In addition, the present invention aims to provide a vacuum cleaner in which a first filter is disposed on the outside of the second cyclone and a second filter is disposed on the inside of the second cyclone, thereby minimizing the overall size.

[0062] Below, refer to Figures 1 to 6The vacuum cleaner 1 according to the first embodiment of the present invention will be described.

[0063] Vacuum cleaner 1 can refer to a vacuum cleaner that is manually operated by the user. For example, vacuum cleaner 1 can refer to a handheld vacuum cleaner or a stick vacuum cleaner.

[0064] On the other hand, in one embodiment of the present invention, the orientation of the vacuum cleaner 1 can be defined with reference to the bottom surface (lower side) of the battery cover 160 placed on the ground.

[0065] At this time, "front" can refer to the direction in which the suction section 120 is arranged with reference to the suction motor 140, and "rear" can refer to the direction in which the handle 150 is arranged with reference to the suction motor 140. Furthermore, based on the view of the suction section 120 from the suction motor 140, the direction on the right can be called the right side, and the direction on the left can be called the left side. Additionally, in one embodiment of the present invention, the upper and lower sides can be defined along a direction perpendicular to the ground, based on the bottom surface (lower side) of the battery cover 160 being placed on the ground.

[0066] Vacuum cleaner 1 may include a body 100. The body 100 may include a body cover 110, a suction unit 120, a first cyclone unit 130, a suction motor 140, a handle 150, and an operating unit 170.

[0067] The main body cover 110 can form the appearance of the vacuum cleaner 1. The main body cover 110 can provide an internal space to accommodate the suction motor 140 and the second filter 500. The main body cover 110 can be constructed in a shape similar to a cylinder.

[0068] The suction unit 120 can be disposed inside the dust bin 200. As an example, the suction unit 120 can be formed in the shape of a tube with an internal opening. The suction unit 120 can be combined with an extension tube (not shown). The suction unit 120 can provide a suction flow path 120a through which dust-containing air can flow.

[0069] The suction unit 120 can be combined with the second cyclone unit 400. The suction unit 120 can be combined with the housing 310, 1310 of the second cyclone unit 400, which will be described later.

[0070] At least a portion of the suction section 120 may be disposed inside the second cyclone section 400. Specifically, at least a portion of the suction section 120 may be disposed surrounded by a plurality of cyclone bodies 410. Therefore, at least a portion of the suction section 120 may extend in the same or parallel direction as the direction in which the suction motor axis a1 extends.

[0071] The suction section 120 can be formed in a curved shape. One end of the suction section 120 can be formed to penetrate the cover body 221 of the discharge cover 220. The other end of the suction section 120 can be formed to penetrate the outer peripheral surface of the second cyclone section 400 (the outer peripheral surface of the housing 310, 1310 or the first filter 320). Thus, air drawn in from the outside through the suction section 120 can flow in the suction flow path 120a and be discharged into the dust bin 200.

[0072] The vacuum cleaner 1 of this invention may be provided with at least one cyclone section capable of separating dust by cyclone flow. For example, the vacuum cleaner 1 may include a first cyclone section 130 and a second cyclone section 400.

[0073] The first cyclone section 130 is configured to separate dust drawn into the interior of the main body 100 through the suction section 120 using the principle of a dust collector utilizing centrifugal force. That is, the first cyclone section 130 refers to the space that generates a cyclone flow that rotates along the inner circumferential surface of the dust bin 200, and the first cyclone section 130 may refer to a part of the space inside the dust bin 200.

[0074] The first cyclone section 130 can communicate with the suction section 120. The first cyclone section 130 can separate the dust sucked into the suction section 120. The space inside the first cyclone section 130 can communicate with the space inside the dust bin 200.

[0075] The cyclone flow generated in the first cyclone section 130 can be caused by the suction force of the suction motor 140.

[0076] The cyclone flow generated in the first cyclone section 130 can be formed between the inner side of the dust bin 200 and the outer side of the housings 310 and 1310 (described later). That is, the cyclone flow can be formed inside the first cyclone section 130.

[0077] The space inside the first cyclone section 130 can communicate with the intake section 120. Air and dust drawn in through the intake section 120 flow along the inner circumferential surface of the first cyclone section 130, thereby generating a cyclone flow inside the first cyclone section 130.

[0078] As an example, the cyclone flow generated in the first cyclone section 130 can be formed in a circular shape around the inner periphery of the dust bin 200. The air drawn in through the suction section 120 can flow in a circular shape along the inner circumferential surface of the dust bin 200 with reference to the central axis a2 of the dust bin, thereby generating a cyclone flow in the internal space of the first cyclone section 130.

[0079] Specifically, when the axis a3 of the cyclone flow generated in the first cyclone section 130 is configured perpendicular to the downward direction of gravity, the air drawn in through the suction section 120 can flow in a circular shape along the inner circumferential surface of the dust bin 200 with reference to the central axis a2 of the dust bin. Alternatively, when the axis a3 of the cyclone flow generated in the first cyclone section 130 is configured parallel to the ground, the air drawn in through the suction section 120 can flow in a circular shape along the inner circumferential surface of the dust bin 200 with reference to the central axis a2 of the dust bin.

[0080] As another example, the cyclone flow generated in the first cyclone section 130 can be formed in a spiral shape along the inner periphery of the dust bin 200. That is, the air drawn in through the suction section 120 flows spirally along the inner periphery of the dust bin 200, thereby generating a cyclone flow in the internal space of the first cyclone section 130.

[0081] Specifically, when the axis a3 of the cyclone flow generated in the first cyclone section 130 is configured to be inclined relative to the ground, the air drawn in by the suction section 120 can flow in a spiral shape along the inner periphery of the dust bin 200.

[0082] The vacuum cleaner 1 of this embodiment may include a second cyclone 400 that further separates dust from the air discharged by the first cyclone 130. That is, the second cyclone 400 can filter out smaller dust particles that were not filtered by the first cyclone 130 and the first filter unit 300 in the air that has passed through the first cyclone 130 and the first filter unit 300.

[0083] At this time, the second cyclone section 400 can be located inside the first cyclone section 130 to minimize the size of the vacuum cleaner 1. The second cyclone section 400 can be configured below the suction motor 140. Specifically, the second cyclone section 400 can be configured inside the first filter unit 300. That is, the first cyclone section 130 and the second cyclone section 400 can be configured inside the dustbin 200, separated by the first filter unit 300.

[0084] The second cyclone section 400 may include a plurality of cyclone bodies 410 arranged side by side. Thus, air discharged from the first cyclone section 130 can be diverted by the first filter unit 300 through the plurality of cyclone bodies 410. That is, the cyclone flow generated in the second cyclone section 400 can be formed inside the cyclone bodies 410.

[0085] On the other hand, the second cyclone section 400 may also include a single cyclone body 410, in which case the axis a3 of the cyclone flow generated by the second cyclone section 400 may also extend in the vertical direction.

[0086] Furthermore, the axis a3 of the cyclone flow generated in the first cyclone section 130 can also extend in the vertical direction. Thus, 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 can be coaxial or parallel in the vertical direction.

[0087] Inside the dust bin 200, storage components 311 and 1311 can be configured to store the dust separated by the second cyclone section 400. The storage components 311 and 1311 can be connected to the lower side of the housings 310 and 1310 and can contact the top surface of the discharge cover 220. In addition, the lower side of the storage components 311 and 1311 can be open.

[0088] Storage components 311 and 1311 can divide the space inside the dust bin 200 into first dust storage sections 311a, 311, and 1311a that store dust separated from the first cyclone section 130 and second dust storage sections 311b, 311, and 1311b that store dust separated from the second cyclone section 400.

[0089] Therefore, the space between the storage components 311, 1311 and the dust bin 200 can be defined as the first dust storage section 311a, 311, 1311a, and the lower internal space of the storage components 311, 1311 can be defined as the second dust storage section 311b, 311, 1311b.

[0090] The discharge cover 220 can open and close the first dust storage section and the second dust storage section together. That is, the first dust storage section and the second dust storage section can be exposed to the outside together.

[0091] The intake motor 140 can generate an intake airflow. The intake motor 140 can be housed within the main body cover 110.

[0092] The suction motor 140 can generate suction by rotating. As an example, the suction motor 140 can be configured to resemble a cylindrical shape.

[0093] At this point, the suction force of the intake motor 140 can be used to generate a cyclone flow.

[0094] Specifically, when the suction motor 140 is driven, the air drawn in through the suction section 120 can generate a cyclone flow in the first cyclone section 130 and / or the second cyclone section 400 by utilizing the suction force of the suction motor 140.

[0095] The vacuum cleaner 1 of the present invention may include a virtual suction motor axis a1 extending the rotation axis of the suction motor 140.

[0096] The suction motor 140 can be located inside the main body cover 110. Furthermore, the suction motor 140 can be located above the second cyclone section 400. Therefore, the suction motor 140 can be positioned above the dust bin 200.

[0097] The suction motor 140 can be connected to the outlet of the second cyclone section 400.

[0098] The shaft a3 of the cyclone flow in the first cyclone section 130 can pass through the suction motor 140.

[0099] In an embodiment of the present invention, if the suction motor 140 is located above the second cyclone section 400, the air discharged from the second cyclone section 400 can flow directly to the suction motor 140, thereby minimizing the flow path between the second cyclone section 400 and the suction motor 140.

[0100] An air outlet 110a can be formed in the main body cover 110 to discharge air drawn in by the suction of the suction motor 140.

[0101] A flow guide may be provided on the main body cover 110. The flow guide can guide the flow of air discharged through the air outlet 110a.

[0102] The handle 150 can be gripped by a user. As an example, the handle 150 can be formed in a shape similar to a cylinder. Alternatively, the handle 150 can be formed in a curved cylindrical shape. The handle 150 can be configured to form a predetermined angle with the body cover 110, the suction motor 140, or the first cyclone section 130.

[0103] The handle 150 may include: a grip portion formed in a column shape so that a user can grip it; a first extension portion connected to one end of the grip portion along the length direction (axial direction) and extending toward the suction motor 140; and a second extension portion connected to the other end of the grip portion along the length direction (axial direction) and extending toward the dust bin 200.

[0104] On the other hand, in this embodiment, a virtual gripping part through-line can be formed that extends along the length direction of the gripping part (the axis of the column) and penetrates the gripping part.

[0105] As an example, the through line of the grip portion can be a virtual line formed inside the cylindrical handle 150, or a virtual line formed parallel to at least a portion of the outer surface (outer peripheral surface) of the grip portion.

[0106] The top surface of the handle 150 can form part of the appearance of the top surface of the vacuum cleaner 1. This prevents a component of the vacuum cleaner 1 from coming into contact with the user's arm when the user is holding the handle 150.

[0107] The first extension can extend from the gripping part to the main body cover 110 or the suction motor 140. At least a portion of the first extension can extend in the horizontal direction.

[0108] The second extension can extend from the grip towards the dust bin 200. At least a portion of the second extension can extend in the horizontal direction.

[0109] The operation unit 170 can be disposed on the main body cover 110. The operation unit 170 can be disposed on the outer side of the main body cover 110. The operation unit 170 can be composed of a plurality of buttons, and when the user presses a button, the corresponding command can be executed. The user can input the start or stop command of the vacuum cleaner 1 through the operation unit 170.

[0110] Vacuum cleaner 1 may include a dustbin 200. The dustbin 200 may communicate with a suction unit 120. A first cyclone unit 130 may be located inside the dustbin 200. The dustbin 200 may store dust separated by the first cyclone unit 130.

[0111] The dust bin 200 may include a dust bin body 210, a discharge cover 220, a dust bin compression rod (not shown), and a compression component (not shown).

[0112] The dust bin body 210 can provide space for storing dust separated by the first cyclone section 130. As an example, the dust bin body 210 can be formed in a shape similar to a cylinder.

[0113] On the other hand, in this embodiment, a virtual dustbin central axis a2 can be formed that penetrates the interior (internal space) of the dustbin body 210 and extends along the length direction of the dustbin body 210 (referring to the axial direction in the cylindrical dustbin body 210). Thus, the length direction axis of the dustbin can refer to the dustbin central axis a2.

[0114] A portion of the lower side (bottom) of the dustbin body 210 may be open. Additionally, a bottom extension (not shown) may be formed on the lower side (bottom) of the dustbin body 210. This bottom extension may be formed to seal a portion of the lower side of the dustbin body 210.

[0115] The dust bin 200 may include a discharge cover 220. The discharge cover 220 may be disposed on the lower side of the dust bin 200.

[0116] The discharge cover 220 can be configured to open and close one end of the dust bin body 210 along its length. Specifically, the discharge cover 220 can selectively open and close the lower part of the downward opening of the dust bin 200.

[0117] The discharge cover 220 may include a cover body 221 and a hinge portion 222. The cover body 221 may be formed to block a portion of the lower side of the dustbin body 210. The cover body 221 may rotate downward about the hinge portion 222. The hinge portion 222 may be configured to be adjacent to the battery cover 160. A torsion spring may be provided in the hinge portion 222. Thus, when the discharge cover 220 is separated from the dustbin body 210, the cover body 221 may be supported by the spring force of the torsion spring in a state where it can rotate more than a predetermined angle from the dustbin body 210 about the hinge portion 222.

[0118] The discharge cover 220 can be engaged with the dust bin 200 via a hook. Alternatively, the discharge cover 220 can be detached from the dust bin 200 using a connecting rod (not shown). The connecting rod (not shown) can be positioned at the front of the dust bin 200. Specifically, the connecting rod (not shown) can be positioned on the outer front side of the dust bin 200. When an external force is applied, the connecting rod (not shown) can elastically deform the hook extending from the cover body 221 to release the hook engagement between the cover body 221 and the dust bin body 210.

[0119] With the discharge cover 220 closed, the lower side of the dust bin 200 can be sealed by the discharge cover 220 and the bottom extension.

[0120] The dustbin 200 may include a dustbin compression rod. The dustbin compression rod may be configured externally to the dustbin 200. The dustbin compression rod may be configured externally to move vertically. The dustbin compression rod may be connected to a compression member (not shown). When the dustbin compression rod moves downwards due to an external force, the compression member (not shown) may also move downwards together. This provides convenience for the user. The compression member (not shown) and the dustbin compression rod may be returned to their original positions by an elastic member (not shown). Specifically, when the external force applied to the dustbin compression rod is removed, the elastic member may cause the dustbin compression rod and the compression member (not shown) to move upwards.

[0121] A compressor (not shown) can be disposed inside the dustbin body 210. The compressor can move within the internal space of the dustbin body 210. Specifically, the compressor can move up and down within the dustbin body 210. This allows the compressor to compress the dust within the dustbin body 210 downwards. Furthermore, when the discharge cap 220 separates from the dustbin body 210, opening the lower part of the dustbin 200, the compressor can move from the upper part of the dustbin 200 downwards to remove any remaining dust or other foreign matter from the dustbin 200. This improves the suction power of the vacuum cleaner by preventing residual dust from remaining in the dustbin 200. Additionally, preventing residual dust from remaining in the dustbin 200 also helps eliminate odors caused by residue.

[0122] The vacuum cleaner 1 may include a battery housing 160. A battery 161 may be housed in the battery housing 160. The battery housing 160 may be positioned below the handle 150. As an example, the battery housing 160 may be a hexahedral shape with an open bottom. The top surface of the battery housing 160 may be connected to the handle 150.

[0123] The battery housing 160 may include a downwardly opening receiving portion. The battery 161 can be loaded and unloaded through the receiving portion of the battery housing 160.

[0124] The battery cover 160 may be provided with battery terminals that are exposed to the outside.

[0125] If the battery terminals of the battery housing 160 are connected to an external charging terminal (not shown), power can be supplied to the battery 161 through the battery terminals. The battery terminals can be separately arranged on the left and right sides of the bottom surface of the battery housing 160.

[0126] Vacuum cleaner 1 may include battery 161.

[0127] For example, battery 161 can be detachably attached to vacuum cleaner 1. Battery 161 can be detachably attached to battery cover 160. As an example, battery 161 can be inserted into the interior of battery cover 160 from below. With the configuration described above, the portability of vacuum cleaner 1 can be improved.

[0128] In contrast, battery 161 can be integrally housed inside battery cover 160. In this case, the bottom surface of battery 161 will not be exposed to the outside.

[0129] The battery 161 stores electrical energy and powers various components, including the suction motor 140 of the vacuum cleaner 1. The battery 161 can be located at the lower part of the handle 150. The battery 161 can also be located on the lower side of the dustbin 200. That is, the suction motor 140 and the battery 161 can be configured not to overlap in the front-to-back direction, and their heights can be different. With the handle 150 as a reference, the heavier suction motor 140 is positioned on the upper side of the handle 150, and the lighter battery 161 is positioned on the lower side of the handle 150, thus evenly distributing the overall weight of the vacuum cleaner 1. This prevents excessive strain on the user's wrists when cleaning by holding the handle 150.

[0130] According to the embodiment, when the battery 161 is attached to the battery cover 160, the bottom surface of the battery 161 can be exposed to the outside. Since the battery 161 can be placed on the floor when the vacuum cleaner 1 is placed on the floor, the battery 161 can be directly separated from the battery cover 160. In addition, since the bottom surface of the battery 161 is exposed to the outside, the battery 161 is in direct contact with the outside air, thereby improving the cooling performance of the battery 161.

[0131] On the other hand, with the battery 161 integrally fixed to the battery cover 160, the structure for attaching and detaching the battery 161 and the battery cover 160 can be reduced, thus reducing the overall size of the vacuum cleaner 1 and achieving weight reduction.

[0132] Vacuum cleaner 1 may include an extension tube (not shown). The extension tube (not shown) may communicate with a cleaning module (not shown). The extension tube (not shown) may communicate with the main body 100. The extension tube (not shown) may communicate with the suction section 120 of the main body 100. The extension tube (not shown) may be formed in a long cylindrical shape.

[0133] The main body 100 can be connected to an extension tube (not shown). The main body 100 can be connected to a cleaning module via the extension tube (not shown). The main body 100 can generate suction using the suction motor 140 and provide suction to the cleaning module through the extension tube (not shown). External dust can flow into the main body 100 through the cleaning module and the extension tube (not shown).

[0134] Vacuum cleaner 1 may include a cleaning module (not shown). The cleaning module (not shown) may be connected to an extension tube (not shown). Thus, outside air can flow into the body 100 of vacuum cleaner 1 via the cleaning module (not shown) and the extension tube (not shown) through the suction generated in the body 100 of vacuum cleaner 1.

[0135] The vacuum cleaner 1 may include a first filter unit 300. The first filter unit 300 can filter the air discharged from the first cyclone section 130. The first filter unit 300 can guide the air that has separated dust when passing through the first cyclone section 130 into the second cyclone section 400.

[0136] The first filter unit 300 may include housings 310 and 1310 and a first filter 320.

[0137] Housings 310 and 1310 can be disposed inside the dust bin 200. Housings 310 and 1310 can be disposed inside the first cyclone section 130.

[0138] A space can be formed inside the housings 310 and 1310. A second cyclone section 400 can be arranged inside the housings 310 and 1310.

[0139] The housings 310 and 1310 can be formed in a cylindrical shape, but are not limited to this.

[0140] The central axis a4 of the housing can extend in the vertical direction. The central axis a4 of the housing can extend along the length direction of the housing 310 and 1310.

[0141] As one example, the central axis a4 of the housing can be coaxial with the axis a3 of the cyclone flow generated in the first cyclone section 130. As another example, the central axis a4 of the housing can be formed parallel to the axis a3 of the cyclone flow generated in the first cyclone section 130. As yet another example, the central axis a4 of the housings 310 and 1310 can be coaxial with the axis a1 of the suction motor.

[0142] The first filter 320 can filter out dust from the air discharged by the first cyclone section 130.

[0143] The first filter 320 may be provided with a plurality of holes having a specified diameter. Thus, larger foreign objects contained in the air discharged from the first cyclone section 130 can be filtered by the first filter 320.

[0144] The first filter 320 may be disposed within the housings 310 and 1310. Alternatively, the first filter 320 may refer to a portion of the housings 310 and 1310. Alternatively, the lower edge of the first filter 320 may be coupled to the housings 310 and 1310.

[0145] Air that has passed through the first filter 320 can flow into the second cyclone section 400 configured inside the housings 310 and 1310.

[0146] At this time, the outer side and / or exterior of the housings 310 and 1310 can refer to the direction facing the first cyclone section 130 with reference to the housings 310 and 1310, and the inner side and / or interior of the housings 310 and 1310 can refer to the direction facing the second cyclone section 400 with reference to the housings 310 and 1310.

[0147] The vacuum cleaner of this embodiment may include a second cyclone section 400.

[0148] The second cyclone section 400 can be configured such that at least a portion thereof is disposed inside the first cyclone section 130, and is capable of separating dust from the air discharged from the first cyclone section 130. If dust is separated from the air using the first cyclone section 130, the air discharged from the first cyclone section 130 can flow into the second cyclone section 400 along the flow path.

[0149] The second cyclone section 400 may be composed of an assembly of axial cyclones configured to separate dust from air flowing in axially.

[0150] The second cyclone section 400 may include a cyclone body 410, an eddy current detector 420, and a strip member 430.

[0151] The cyclone body 410 is constructed using the principle of a dust collector that utilizes centrifugal force to separate dust from the air that has passed through the first filter unit 300. Specifically, the cyclone body 410 can separate dust from the air that has passed through the first filter 320 using cyclone flow. Since an airflow space can be formed inside the cyclone body 410, the air that has passed through the first filter 320 can flow into the inside of the cyclone body 410.

[0152] The cyclone body 410 can be disposed inside the housings 310 and 1310. Specifically, at least a portion of the cyclone body 410 can be disposed inside the housings 310 and 1310, and air that has passed through the first filter 320 can flow into the inside of the cyclone body 410.

[0153] Multiple cyclone bodies 410 can be provided. Each cyclone body 410 can have an inlet forming an outer wall around the periphery of its hollow portion. The outer wall around the periphery of the hollow portion formed by the cyclone body 410 can correspond to the outer wall of each axial flow cyclone. Air discharged from the first cyclone section 130 can flow into the inner side of the cyclone body 410 through the inlet. The air rotating along the inner circumferential surface of the cyclone body 410 can form a cyclone flow.

[0154] Dust particles heavier than air can rotate within the cyclone by drawing a larger radius of rotation than air. Since the dust rotates inside the cyclone body 410, the maximum radius of rotation of the dust particles can be limited by the cyclone body 410.

[0155] The lower part of the cyclone body 410 may have an inclined shape that narrows towards the bottom. The lower part of the cyclone body 410 having a shape that narrows towards the bottom is to guide the dust separated from the air to fall and to prevent dust from being discharged with the air toward the eddy current detector 420.

[0156] A discharge port can be formed at the lower part of the cyclone body 410. That is, dust separated from the air inside the cyclone body 410 can be discharged from the cyclone body 410 through the discharge port. In addition, the lower part of the cyclone body 410 can communicate with the internal space of the storage members 311 and 1311. Thus, dust rotating with the cyclone inside the cyclone body 410 can fall and be stored in the storage members 311 and 1311. The dust stored in the storage members 311 and 1311 can communicate with the external space when the discharge cover 220 is open.

[0157] The upper part of the cyclone body 410 can be configured to accommodate the eddy current detector 420. The upper part of the cyclone body 410 can be configured to have a specified inner diameter. The upper and lower parts of the cyclone body 410 can be divided based on the position where the inner diameter decreases.

[0158] The outer peripheral surface of each cyclone body 410 can also be connected to the surrounding cyclone bodies 410, thereby forming a single component from multiple cyclone bodies 410. As shown in the figure, it is preferable that the cross-section of each cyclone body 410 is circular. This is because if the cross-section of the cyclone body 410 is circular, even if the outer peripheral surfaces of adjacent cyclone bodies 410 are in close contact with each other, air and dust flow paths can be formed between them. If air and dust flow paths are formed between the cyclone bodies 410, it has the advantage that no additional flow path structures are required.

[0159] This does not preclude the cross-section of each cyclone body 410 from being polygonal. However, even if the cross-section of each cyclone body 410 is polygonal, it is preferable to form a polygon that can create flow paths for air and dust.

[0160] The eddy current detector 420 is composed of air discharged from the inside of the cyclone body 410 through the cyclone flow.

[0161] An airflow path can be formed inside the eddy current detector 420. A plurality of eddy current detectors 420 can be provided, with at least a portion of each eddy current detector 420 disposed inside the cyclone body 410. The outer peripheral surface of each eddy current detector 420 can be separated from the inner peripheral surface of each cyclone body 410. Each eddy current detector 420 has an inlet forming an outer wall around the periphery of the hollow portion, through which air passing through the cyclone body 410 can be discharged. Furthermore, air flowing in from the inlet of the eddy current detector 420 can flow upwards and be discharged from the outlet of the eddy current detector 420.

[0162] The lower part of the eddy current detector 420 may have a greater height than the strip member 430. However, the upper part of the eddy current detector 420 may have the same height as the strip member 430. The lower end of the eddy current detector 420 protrudes downwards from the strip member 430, while the upper end does not.

[0163] Preferably, the cross-section of each eddy current detector 420 is circular hook-shaped. This does not preclude the cross-section of each eddy current detector 420 from being polygonal. However, even if the cross-section of each eddy current detector 420 is polygonal, it is preferable to be polygonal in shape that can form a flow path for air and dust.

[0164] The strip member 430 can be formed to surround the outer peripheral surface of the eddy current detector 420. The strip member 430 can be named differently as needed. For example, it can be called a hook, ring, edge, periphery, circle, support, connecting part, outer contour, cyclone boundary, outer wall, or other names.

[0165] The strip member 430 can be disposed on the first filter 320 and can have a shape corresponding to the upper part of the first filter 320. The upper edge of the first filter 320 can be formed as a circle, and the strip member 430 can also be formed as a circle surrounding the eddy current detector 420. However, it is not excluded that the upper part of the first filter 320 and the strip member 430 are formed as polygons.

[0166] The guide vanes (not shown) are configured to guide the air discharged from the first cyclone section 130 toward the inside of the cyclone body 410. The guide vanes (not shown) can form a flow path that allows the air flowing in through the inlet to flow toward the inside of the cyclone body 410. Thus, the air flowing along the flow path formed by the guide vanes (not shown) can create a vortex between the eddy current detector 420 and the cyclone body 410.

[0167] At least a portion of the guide vanes (not shown) are disposed between the cyclone body 410 and the eddy current detector 420, and are connected to each cyclone body 410 and each eddy current detector 420. One side of the guide vanes (not shown) can be connected to the outer surface of the eddy current detector 420 in a helical direction, and the other side of the guide vanes (not shown) can be connected to the inner surface of the cyclone body 410 in a helical direction.

[0168] Each cyclone body 410 and each eddy current detector 420 may be provided with a plurality of guide vanes (not shown), which may extend in a spiral direction to generate swirling flow. As the guide vanes (not shown) extend in a spiral direction, air and dust flowing in from the inlet of the cyclone body 410 may form swirling flow.

[0169] The flow of air in the flow path of the vacuum cleaner 1 in this embodiment of the invention will be described below.

[0170] First, if the suction motor 140 is running, outside air can flow into the dust bin 200 through the suction unit 120.

[0171] Air with dust separated by the first cyclone section 130 inside the dust bin 200 flows into the inner side of the cyclone body 410 after passing through the first filter 320. The air flowing into the inner side of the cyclone body 410 forms a swirling current as it falls, then flows upwards and passes through the eddy current detector 420. The air passing through the eddy current detector 420 can be filtered for dust in the second filter 500. The air filtered for dust in the second filter 500 can then flow to the suction motor 140, which is located downstream of the intake airflow. The air passing through the suction motor 140 can be discharged to the outside through the air outlet 110a.

[0172] On the other hand, the vacuum cleaner 1 of the first embodiment of the present invention may include a body 100, a suction part 120, a first filter 320, a second filter 500, and a cleaning unit 600.

[0173] At least a portion of the first filter 320 may be disposed inside the dust bin 200. The first filter 320 can filter dust from the air flowing in through the suction section 120. The first filter 320 may be configured to surround the second cyclone section 400. For example, the first filter 320 may be a mesh filter. Additionally, if the suction motor 140 is driven, the suction airflow can pass from the outside to the inside of the first filter 320.

[0174] The second filter 500 can filter dust from the air that has passed through the first filter 320. For example, the second filter 500 can be a pre-filter. Additionally, the second filter 500 can be shaped like a cylinder with an internal opening. Furthermore, if the suction motor 140 is driven, the suction airflow can pass from the outside to the inside of the second filter 500.

[0175] The first filter 320 and the second filter 500 can be arranged vertically along the central axis a2 of the dust bin. Furthermore, the length axis of the first filter 320 and the length axis of the second filter 500 can be coaxial, and the length axes of the first filter 320 and the second filter 500 can be collectively referred to as the length axis a5 of the filters.

[0176] At this point, the central axis a2 of the dust bin and the longitudinal axis a5 of the filter can be coaxial.

[0177] Dust filtered by the first filter 320, i.e., the first dust, can accumulate on the first filter surface. The first filter surface can refer to the outer surface of the first filter 320. Specifically, the first filter surface can refer to the surface of the first filter 320 that faces the inner surface of the dust bin body 210.

[0178] Dust filtered by the second filter 500, i.e., second dust, can accumulate on the second filter surface. The second filter surface can refer to the outer surface of the second filter 500. Specifically, the second filter surface can refer to the surface of the second filter 500 that faces the inner surface of the filter housing 180.

[0179] The cleaning unit 600 can be configured to move relative to the first filter 320 and the second filter 500.

[0180] The cleaning unit 600 can clean the first dust and the second dust from the first filter surface and the second filter surface, respectively.

[0181] The virtual suction motor axis a1, which extends the rotation axis of the suction motor 140, and the length axis of the dust bin (dust bin center axis a2) can intersect each other. Consequently, the suction motor axis a1 and the length axis a5 of the filter can also intersect each other.

[0182] The suction unit 120 and the suction motor 140 can be configured on opposite sides of each other with reference to the longitudinal axis of the dustbin (the central axis a2 of the dustbin). With this configuration, the overall center of gravity of the vacuum cleaner is configured as close as possible to the handle 150 held by the user, so that the user can move the vacuum cleaner 1 with minimal force.

[0183] The main body 100 may also include a filter housing 180.

[0184] An accommodating space 180a for accommodating the second filter 500 can be formed inside the filter housing 180. In addition, the dust bin 200 can be detachably attached to the filter housing 180.

[0185] The filter housing 180 and the dust bin 200 can be configured vertically along the central axis a2 of the dust bin or the length axis a5 of the filter.

[0186] A filter inlet / outlet portion 180b, through which the second filter 500 can enter and exit, can be formed on the upper side of the filter housing 180. Thus, the user can use the filter inlet / outlet portion 180b to remove the second filter 500 to the outside.

[0187] The filter inlet / outlet 180b can be opened and closed using the filter inlet / outlet cover 190. The filter inlet / outlet cover 190 can be hinged to the filter housing 180, allowing the filter inlet / outlet 180b to be opened when it is desired to remove the second filter 500 to the outside.

[0188] The cleaning unit 600 may include a first movable part 610, a second movable part 620, a connecting part 630, an operating cover 640, a guide member 650, an operating lever 660, and an elastic member 670.

[0189] The first movable part 610 can move within the dust bin 200 along the space between the first filter surface and the inner side of the dust bin 200.

[0190] A first brush 611, consisting of a plurality of bristles, may be disposed inside the first movable part 610. If the first movable part 610 moves along the central axis a2 of the dust bin, the first brush 611 can clean the dust accumulated on the first filter surface.

[0191] The second movable part 620 can move within the filter housing 180 along the space between the second filter surface and the inner side of the filter housing 180.

[0192] A second brush 621, consisting of a plurality of bristles, may be disposed inside the second movable part 620. If the second movable part 620 moves along the central axis a2 of the dust bin, the second brush 621 can clean the dust accumulated on the second filter surface.

[0193] The connecting part 630 can connect the first movable part 610 and the second movable part 620.

[0194] Therefore, if the operating lever 660 moves, the first movable part 610 and the second movable part 620 can move together.

[0195] The connecting part 630 can penetrate the filter housing 180. Specifically, a movable hole (not shown) is formed through the filter housing 180, through which the connecting part 630 can move. The connecting part 630 can move in a direction parallel to the central axis a2 of the dust bin through the movable hole (not shown).

[0196] Thus, a portion of the connecting part 630 is disposed in the space between the first filter surface and the dust bin 200, and the remaining portion of the connecting part 630 can be disposed in the space between the second filter surface and the inner side of the filter cover 180.

[0197] The connecting part 630 may include a first connecting member 631 and a second connecting member 632.

[0198] One side of the first connecting member 631 can be movably connected to the guide member 650, while the other end can be fixed to the first movable part 610.

[0199] On the other hand, elastic members 670 may be arranged on both sides of the first connecting member 631 that is combined with the guide member 650.

[0200] The elastic member 670 is configured to surround the guide member 650 (described later) and is capable of generating a restoring force in the opposite direction to the direction of movement of the operating lever 660 when the user moves the operating lever 660.

[0201] The elastic member 670 may include a first elastic member 671 and a second elastic member 672.

[0202] A first elastic member 671 may be disposed on one side of the first connecting member 631, and a second elastic member 672 may be disposed on the other side. One side of the first elastic member 671 may be connected to the operating lever 660 and the guide member 650, while the other side may be connected to the first connecting member 631. One side of the second elastic member 672 may be connected to the first connecting member 631, while the other side may be connected to the guide member 650.

[0203] In addition, one side of the second connecting member 632 can be fixed to the first movable part 610, while the other side can be fixed to the second movable part 620.

[0204] Therefore, if the operating lever 660 moves and the elastic member 670 is compressed, the first connecting member 631 can move along with the guide member 650. In addition, the first movable part 610 connected to the first connecting member 631 and the second movable part 620 connected to the second connecting member 632 can also move.

[0205] The operating cover 640 can be attached to the outside of the main body 100 and the dust bin 200. The guide member 650 can be accommodated inside the operating cover 640.

[0206] The internal space of the operating cover 640 can communicate with the internal space of the dust bin 200. A movable slit (not shown) corresponding to the length direction of the operating cover 640 can be formed in the dust bin 200, and the connecting part 630 can be connected to the guide member 650 when passing through the movable slit (not shown).

[0207] The guide member 650 can extend inside the operating cover 640 along the movement direction of the first movable part 610 and the second movable part 620.

[0208] The lever 660 can slide along the guide member 650, and at least a portion of the lever 660 is exposed to the outside so that the user can hold it.

[0209] The filter inlet / outlet 180b can open toward the direction of elastic member 670 elastically resetting.

[0210] When the direction in which the elastic member 670 is compressed is referred to as the first direction, and the direction in which the elastic member 670 is elastically reset is referred to as the second direction, if the user moves the operating lever 660 in the first direction and then releases the operating lever 660, the second brush 621 can move in the second direction while simultaneously moving the second filter 500 toward the filter inlet / outlet 180b. Thus, with the filter inlet / outlet 180b open, at least a portion of the second filter 500, moved by the second brush 621, can be exposed to the outside through the filter inlet / outlet 180b.

[0211] On the other hand, refer to Figure 6 In the vacuum cleaner 1 of the first embodiment of the present invention, four quadrants can be defined by the horizontal center line HL1 and the vertical center line VL1.

[0212] With a reference point when viewed from the filter inlet / outlet cover 190 toward the outlet cover 220, the transverse centerline HL1 can pass horizontally through the center of the dust bin body 210 and through the outer peripheral surface of the dust bin body 210. In this case, the horizontal direction can refer to the direction that intersects perpendicularly with the length axis of the suction section 120.

[0213] The vertical center line VL1 can intersect the horizontal center line HL1 perpendicularly, pass vertically through the center of the dust bin body 210, and extend parallel to the length direction of the suction part 120.

[0214] The connecting part 630 and the guiding member 650 can be configured in the same quadrant of the four quadrants divided by the transverse centerline HL1 and the vertical centerline VL1.

[0215] With this structure, the connecting part 630 and the guide member 650 can be configured as close as possible, thus minimizing the distance between the operating lever 660 and the cleaning unit 600 when the user is holding the operating lever 660. Therefore, when the user wants to clean the dust accumulated in the first filter 320 and / or the second filter 500 by moving the cleaning unit 600, the user can move the operating lever 660 with minimal force.

[0217] Below, refer to Figures 7 to 13 The vacuum cleaner 2 of the second embodiment of the present invention will be described.

[0218] The vacuum cleaner 2 of the second embodiment of the present invention may include a body 100, a suction unit 120, a first filter 1320, a second filter 1500, and a cleaning unit 1600.

[0219] On the other hand, to avoid repetitive descriptions, except for the content specifically mentioned in the second embodiment of the present invention, other descriptions of the components may refer to the content of the vacuum cleaner in the first embodiment of the present invention.

[0220] At least a portion of the first filter 1320 may be disposed inside the dust bin 200, and the first filter 1320 may filter dust from the air flowing in through the suction section 120. The first filter 1320 may be configured to surround the second cyclone section 400. For example, the first filter 1320 may be a mesh filter. Additionally, if the suction motor 140 is driven, the suction airflow may pass from the outside to the inside of the first filter 1320.

[0221] The second filter 500 can filter dust from the air that has passed through the first filter 1320. For example, the second filter 1500 can be an open pre-filter. Alternatively, the second filter 1500 can be shaped like a cylinder with an internal opening. Furthermore, if the suction motor 140 is driven, the suction airflow can pass from the outside to the inside of the second filter 1500.

[0222] At least a portion of the second filter 1500 may be configured inside the first filter 1320.

[0223] In the vacuum cleaner 2 of the second embodiment of the present invention, the second filter 1500 is disposed inside the first filter 1320, thus having the advantage of miniaturizing the vacuum cleaner 2.

[0224] The first filter 1320 and the second filter 1500 can be coaxial, and the length direction axis of the first filter 1320 and the second filter 1500 can be collectively referred to as the length direction axis a6 of the filter.

[0225] At this time, the suction motor axis of the extended suction motor 140, the dust bin center axis a2, the cyclone flow axis a3, the housing center axis a4, and the filter length direction axis a6 can be coaxial.

[0226] Dust filtered by the first filter 1320, i.e., the first dust, can accumulate on the first filter surface. The first filter surface can refer to the outer surface of the first filter 1320. Specifically, the first filter surface can refer to the surface of the first filter 1320 that faces the inner surface of the dust bin body 210.

[0227] Dust filtered by the second filter 1500, i.e., second dust, can accumulate on the second filter surface. The second filter surface can refer to the outer surface of the second filter 1500. Specifically, the second filter surface can refer to the surface of the second filter 1500 that faces the inner surface of the filter housing 1180.

[0228] The cleaning unit 1600 can be configured to move relative to the first filter 1320 and the second filter 1500.

[0229] The cleaning unit 1600 can clean the first dust and the second dust from the first filter surface and the second filter surface, respectively.

[0230] The vacuum cleaner 2 of the second embodiment of the present invention may further include a filter cover 1180.

[0231] An accommodating space 1180a capable of accommodating the second filter 1500 can be formed inside the filter housing 1180. The filter housing 1180 can be detachably attached to the main housing 110. At least a portion of the filter housing 1180 can be disposed inside the dust bin 200. The filter housing 1180 can be formed into a cylindrical shape with an internal opening.

[0232] Reference Figure 10 The first filter 1320 can be configured to surround at least a portion of the filter housing 1180.

[0233] A second cyclone section 400 may be disposed inside the filter housing 1180. Specifically, a plurality of cyclone bodies 410 may be disposed inside the filter housing 180 and configured to surround the second filter 1500 with the second filter 1500 as the center.

[0234] The cleaning unit 600 may include a first movable part 1610, a second movable part 1620, a connecting part 1630, an operating cover 1640, a guide member 1650, an operating lever 1660, and an elastic member (not shown).

[0235] The first movable part 1610 can move within the dust bin 200 along the space between the first filter surface and the inner side of the dust bin 200.

[0236] A first brush 611, consisting of a plurality of bristles, may be disposed on the inner side of the first movable part 1610. If the first movable part 1610 moves along the central axis a2 of the dust bin, the first brush 1611 can clean the dust accumulated on the first filter surface.

[0237] The second movable part 1620 can move within the filter housing 1180 along the space between the second filter surface and the inner side of the filter housing 1180.

[0238] A second brush 1621, consisting of a plurality of bristles, may be disposed inside the second movable part 1620. If the second movable part 1620 moves along the central axis a2 of the dust bin, the second brush 1621 can clean the dust accumulated on the second filter surface.

[0239] The connecting part 1630 can connect the first movable part 1610 and the second movable part 1620.

[0240] The connecting part 1630 can penetrate the filter housing 1180. Specifically, a movable hole (not shown) is formed in the filter housing 1180 through which the connecting part 1630 can move, and the connecting part 1630 can move in a direction parallel to the central axis a2 of the dust bin through the movable hole (not shown).

[0241] Thus, a portion of the connecting part 1630 can be disposed in the space between the filter housing 1180 and the dust bin 200, and the remaining portion of the connecting part 1630 can be disposed in the space between the second filter surface and the inner surface of the filter housing 1180.

[0242] The elastic member (not shown) is configured to surround the guide member 1650 described later, and is capable of generating a restoring force in the opposite direction to the direction of movement of the operating lever 1660 when the user moves the operating lever 1660.

[0243] One side of the elastic member (not shown) can be connected to the operating lever 1660, and the other end can be connected to the connecting part 1630. Thus, if the operating lever 1660 moves and the elastic member (not shown) is compressed, the first movable part 1610, the second movable part 1620, and the connecting part 1630 can move along the length direction of the guide member 1650.

[0244] The operating cover 1640 can be attached to the outside of the main body 100 and the dust bin 200. The guide member 1650 can be accommodated inside the operating cover 1640.

[0245] The internal space of the operating cover 1640 can communicate with the internal space of the dust bin 200. A movable slit (not shown) corresponding to the length direction of the operating cover 1640 can be formed in the dust bin 200, and the connecting part 1630 can be connected to the guide member 1650 when passing through the movable slit (not shown).

[0246] The guide member 1650 can extend inside the operating cover 1640 along the movement direction of the first movable part 1610 and the second movable part 1620.

[0247] The lever 1660 can slide along the guide member 1650, and at least a portion of the lever 1660 can be exposed to the outside so that the user can hold it.

[0248] On the other hand, refer to Figure 13 In the vacuum cleaner 2 of the second embodiment of the present invention, four quadrants can be defined by the horizontal center line HL2 and the vertical center line VL2.

[0249] With reference to the view from the air exhaust cover 111 to the exhaust cover 220 (described later), the transverse centerline HL2 can pass through the center of the dust bin body 210 in a horizontal direction and penetrate the outer peripheral surface of the dust bin body 210. In this case, the horizontal direction can refer to the direction that intersects perpendicularly with the length axis of the suction section 120.

[0250] The vertical center line VL2 can intersect the horizontal center line HL2 perpendicularly, pass through the center of the dust bin body 210 perpendicularly, and extend parallel to the length direction of the suction section 120.

[0251] The connecting part 1630 and the guide member 1650 can be configured in the same quadrant of the four quadrants divided by the transverse center line HL2 and the vertical center line VL2.

[0252] With this structure, the connecting part 1630 and the guide member 1650 can be configured as close as possible, thus minimizing the distance between the operating lever 1660 and the cleaning unit 1600 when the user is holding the operating lever 1660. Therefore, when the user wants to clean the dust accumulated in the first filter 1320 and / or the second filter 1500 by moving the cleaning unit 1600, the user can move the operating lever 1660 with minimal force.

[0253] On the other hand, the vacuum cleaner 2 of the second embodiment of the present invention may include an air exhaust cover 111. The air exhaust cover 111 may be disposed on one axial side of the main body cover 110. A filter for filtering air may be accommodated in the air exhaust cover 111. As an example, a high-efficiency particulate air (HEPA) filter may be accommodated in the air exhaust cover 111.

[0254] An air outlet 112 can be formed in the air outlet cover 111 to discharge air drawn in by the suction of the suction motor 140.

[0255] A flow guide may be provided on the air exhaust cover 111. The flow guide can guide the flow of air discharged through the air exhaust port 112.

[0256] On the other hand, the vacuum cleaners 1 and 2 of the present invention can be combined with a vacuum cleaner base station that is equipped with a dust collection motor that generates suction airflow and a dust collection section that collects dust stored in the dust bin 200 of the vacuum cleaners 1 and 2. At this time, if suction airflow from the dust collection motor is generated in a state where the internal space of the dust bin 200 and the dust collection section are connected by an additional flow path, the dust stored in the dust bin 200 of the vacuum cleaners 1 and 2 can be moved to the dust collection section.

[0257] Therefore, if the vacuum cleaners 1 and 2 of the present invention are combined with the vacuum cleaner base station and the dust collection motor is driven with the discharge cover 220 open, the dust from the first filter 320, 1320 and the second filter 500, 1500 cleaned by the cleaning units 600 and 1600 can be captured in the dust collection section.

[0258] The above description, through specific embodiments of the present invention, is only for illustrating the present invention. The present invention is not limited thereto. Obviously, the present invention can be modified or improved by those skilled in the art within the scope of the technical concept of the present invention.
