Description

Vacuum cleaners, vacuum cleaner stations, and vacuum cleaner systems

[0001] The present invention relates to a vacuum cleaner, a vacuum cleaner station, and a vacuum cleaner system, and more particularly, to a vacuum cleaner, a vacuum cleaner station, and a vacuum cleaner system capable of collecting dust from a dust bin of the vacuum cleaner into a vacuum cleaner station using a suction motor provided in the 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 ease of use, are being widely used.

[0006] The canister-type vacuum cleaner has 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 area they can be cleaned 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] However, conventional handheld vacuum cleaners and stick vacuum cleaners had a small dustbin capacity for storing collected dust, which was inconvenient for users to have to empty the dustbin every time.

[0010] Additionally, there was a problem that when the dustbin was emptied, dust would fly around, which had a harmful effect on the user's health.

[0011] Additionally, there was a problem that the suction power of the vacuum cleaner was reduced if the remaining dust in the dustbin was not removed.

[0012] Additionally, there was a problem of bad odor caused by residue if the remaining dust in the dustbin was not removed.

[0013] To solve this problem, international patent publication WO 2023 / 214166A1 discloses a docking station that collects dust stored in the dust bin of a vacuum cleaner.

[0014] The above docking station has an intermediate chamber for guiding dust stored in the dust bin to a dust bag, and a hole is formed on the intermediate chamber.

[0015] Accordingly, when the vacuum cleaner's dust bin is opened, dust can fall downwards due to gravity and be stored in the dust bag.

[0016] On the other hand, multiple holes are formed along the circumference on the outside of the dustbin, and when the suction motor is operated, outside air is drawn in and creates a cyclonic flow inside the dustbin.

[0017] Meanwhile, when the suction motor is operated while the dustbin is connected to the docking station, the docking station sucks in air from the outside of the dustbin through the hole in the middle chamber and sucks it into the dustbin of the vacuum cleaner.

[0018] However, in the case of the above-mentioned docking station, although dust can be emptied by gravity, the dust collection path through which dust is discharged from the dust bin to the docking station and the exhaust path through which air inside the docking station is discharged to the suction motor by the suction force of the suction motor exist in the same space. Therefore, there is a high possibility of vortices, etc., occurring inside the dust bin or chamber, and there is a limit to dust being scattered to the outside when the dust bin and docking station are separated.

[0019] Additionally, there is a limit to how much dust remaining inside the middle chamber of the dustbin and docking station can flow into the suction motor, causing a malfunction in the suction motor.

[0020]

[0021] The present invention was created to improve the problems of the conventional vacuum cleaner, vacuum cleaner station and vacuum cleaner system as described above, and the purpose of the present invention is to provide a vacuum cleaner, vacuum cleaner station and vacuum cleaner system that can collect dust from a dust bin of the vacuum cleaner using a suction motor provided in the vacuum cleaner.

[0022] Additionally, the purpose is to provide a vacuum cleaner, a vacuum cleaner station and a vacuum cleaner system that can prevent dust from flying when the dust bin is emptied.

[0023] In addition, the purpose is to provide a cleaner, a cleaner station and a cleaner system that open the dustbin cover of the cleaner and change the internal flow path of the cleaner by connecting the cleaner to the cleaner station.

[0024] In addition, the purpose is to provide a vacuum cleaner station and a control method of the vacuum cleaner station that can provide user convenience by removing dust inside a dust bin without separate operation by the user.

[0025] In addition, the purpose is to provide a vacuum cleaner station and a control method for the vacuum cleaner station that can eliminate odor caused by residue by preventing residual dust from remaining in the dust bin.

[0026]

[0034] In addition, the above-mentioned connecting portion may have one end of the length of the dustbin inserted into the inner surface.

[0035] At this time, a push part that presses a lever to open the discharge cover of the dust bin when the dust bin is combined may be provided on the inner surface of the above-mentioned connecting part.

[0036] Meanwhile, the cleaner station according to the present invention may further include an inclined surface formed inside the housing, positioned on the lower side of the inner surface of the coupling portion, and formed to be inclined with respect to the longitudinal direction of the housing.

[0037] In addition, the cleaner station according to the present invention may further include a dust separation unit disposed within the housing and separating dust from air flowing in from the dust bin.

[0038] At this time, the dust separation unit can be connected to the lower end of the dust collection path and the lower end of the exhaust path.

[0039] At this time, the lower end of the exhaust path may be placed higher from the ground than the lower end of the dust collection path.

[0040] Additionally, the upper part of the exhaust path may be positioned higher from the ground than the upper part of the dust collection path.

[0079] In addition, the following examples are provided to more completely explain to a person having average knowledge in the art, and the shapes and sizes of elements in the drawings may be exaggerated for clearer explanation.

[0080]

[0081] FIG. 1 is a perspective view of a cleaning system comprising a cleaning station and a cleaner according to an embodiment of the present invention.

[0082] Referring to FIG. 1, a vacuum cleaner system (1) according to one embodiment of the present invention is described as follows.

[0083] A cleaner system (1) according to one embodiment of the present invention includes a cleaner station (100) and a cleaner (200).

[0084] At this time, a cleaner (200) may be mounted on the cleaner station (100). Specifically, a dust bin () of the cleaner (200) may be coupled to the cleaner station (100). At this time, the internal space of the dust bin () may be communicated with a path formed in the cleaner station (100). In addition, the path formed in the cleaner station (100) may be communicated with the internal space of the main body housing () of the cleaner (200). Accordingly, when the suction motor () of the cleaner (200) is operated, the cleaner station (100) may collect dust in the dust bin ().

[0085]

[0086] Meanwhile, FIG. 2 is a perspective view of a cleaner station according to an embodiment of the present invention, FIG. 3 is a perspective view for explaining a dust bin mounting portion in a cleaner station according to an embodiment of the present invention, FIG. 4 is a drawing for explaining a striker and a spring in a cleaner station according to an embodiment of the present invention, FIG. 5 is a cross-sectional view of FIG. 2, and FIG. 6 is a drawing for explaining a dust collection path and an exhaust path in a cleaner station according to an embodiment of the present invention.

[0087] Referring to FIGS. 2 to 6, a cleaner station (100) according to one embodiment of the present invention will be described as follows.

[0088] A vacuum cleaner (200) can be coupled to the vacuum cleaner station (100). Specifically, a dust bin () of the vacuum cleaner (200) can be coupled to the vacuum cleaner station (100).

[0089] The cleaner station (100) may include a housing (110). The housing (110) may form the exterior of the cleaner station (100). Specifically, the housing (110) may be arranged in an up-down direction.

[0090] The housing (110) includes a housing body (111). The housing body (111) is provided with a coupling portion (120), and at least a portion of the cleaner (200) can be mounted thereon. In addition, the housing body (111) can be positioned at a predetermined height from the floor. At this time, a dust collection portion (150) can be positioned between the housing body (111) and the floor.

[0091] For example, the housing body (111) may be in the shape of a cylinder or polygonal pillar formed along the overall vertical direction. At this time, at least a portion of the cleaner (200) may be mounted on the upper side of the housing body (111), and a dust collection unit (150) may be coupled to the lower side of the housing body (111).

[0092] The housing body (111) may have a space formed therein that can accommodate components of the cleaner station (100). Specifically, at least a portion of the coupling portion (120), the dust collection path portion (160), and the exhaust path portion (170) may be arranged inside the housing body (111).

[0093] The housing (110) further includes a bottom support plate (112).

[0094] The floor support plate (112) is placed at the lowest part of the vacuum cleaner system (1) and can support the entire vacuum cleaner system (1).

[0095] At this time, the floor support plate (112) is placed to face the floor and can support the cleaner station (100) by making contact with the floor. Here, the floor can mean not only the outdoor ground but also the floor surface of each floor within the building.

[0096] Meanwhile, the floor support plate (112) can be positioned parallel to the floor, or it can be positioned at a predetermined angle relative to the floor. This configuration has the advantage of balancing the overall weight even when the vacuum cleaner (200) is coupled to the vacuum cleaner station (100).

[0097] The floor support plate (112) may be formed to have a wider area than the horizontal plane area of ​​the housing body (111). In addition, the floor support plate (112) may be formed to extend further forward than the housing body (111). Through this, the floor support plate (112) may be arranged vertically below the nozzle () of the cleaner when the cleaner (200) is placed. Accordingly, even if foreign substances such as dust fall from the nozzle () of the cleaner, they fall onto the floor support plate (112), thereby preventing the floor from being contaminated.

[0098] It is preferable that the floor support plate (112) be arranged symmetrically to maintain the left-right balance and front-back balance on which the vacuum cleaner (200) is mounted. For example, the floor support plate (112) may be a rectangular or oval plate.

[0099] Meanwhile, for the purpose of understanding this embodiment, the direction is defined as follows. In this embodiment, the direction can be defined while the cleaner (200) is mounted on the cleaner station (100).

[0100] At this time, the direction in which the suction part (212) of the cleaner is arranged with respect to the mounting surface (131) of the cleaner station (100) can be referred to as the front (see Fig. 1). In addition, the direction in which the support frame (113) is arranged with respect to the mounting surface (131) can be referred to as the rear. In addition, the left and right can be defined based on a view looking forward from the rear.

[0101] The housing (110) further includes a support frame (113).

[0102] The support frame (113) is connected to the outer surface of the housing body (111) and may be formed in an up-down direction. For example, the support frame (113) may be formed in a polygonal column shape. In this case, at least one side of the support frame (113) may be formed in a curved shape.

[0103] The upper part of the support frame (113) can be connected to the dustbin mounting part (130), and the lower part can be combined with the floor support plate (112).

[0104] With this configuration, the support frame (113) is supported by the bottom support plate (112) and can support the housing body (111) and the dustbin mounting portion (130).

[0105]

[0106] The vacuum cleaner station (100) may include a coupling part (120) to which a vacuum cleaner (200) is coupled. Specifically, the coupling part (120) is placed inside the housing body (111), and a dust bin (220) of the vacuum cleaner (200) may be coupled.

[0107] For example, the upper part of the coupling part (120) may be formed in a cylindrical shape. At this time, the dust bin (220) of the vacuum cleaner may be inserted and coupled to the inner surface (121) of the coupling part (120). At this time, the inner diameter of the inner surface (121) may be the same as the outer diameter of the dust bin (220) or slightly larger than the outer diameter of the dust bin (220). Accordingly, the dust bin (220) may be inserted and supported in the inner surface (121).

[0108] At this time, the axial length (height) of the inner surface (121) may be formed differently depending on the location. For example, the height of the portion positioned forward among the inner surface (121) may be smaller than the height of the portion positioned rearward. Through this, sufficient rotational space can be provided when the discharge cover (222) is opened.

[0109] Meanwhile, a push portion (122) that is formed to be sunken radially outward on the rear surface of the inner surface (121) of the connecting portion (120) can be formed. Through this, when the dust bin (220) is inserted into the connecting portion (120), a cover opening lever (221b) for opening and closing the dust bin (220) can be accommodated.

[0110] At this time, the push part (122) can pressurize the cover opening lever (221b) when the dust bin (220) is inserted into the inner surface (121).

[0111] Therefore, according to the present invention, the discharge cover (222) of the dust bin (220) can be automatically opened simply by the user's action of connecting the dust bin (220) to the connecting portion (120).

[0112] In particular, there is an advantage in that the dustbin (220) can be automatically opened only by the physical force of the user combining the dustbin (220) without a special driving device.

[0113] Meanwhile, the connecting portion (120) can be connected to the dust collection path (161) when one end of the longitudinal direction of the dust bin (220) is connected and the discharge cover (222) is opened. Therefore, when the discharge cover (222) is opened, dust inside the dust bin (220) can flow into the connecting portion. That is, the space formed on the radially inner side of the inner circumference (121) can become a dust inlet (123).

[0114] Meanwhile, the connecting portion (120) may further include an inclined surface (124). The inclined surface (124) may be positioned on the lower side of at least a portion of the inner surface (121) and may be formed to be inclined with respect to the longitudinal direction of the housing (110). For example, the inclined surface (124) may be formed in a form connected to the inner surface (121), and may be formed to be inclined downward from the front end of the inner surface toward the rear.

[0115] With this configuration, when the dust bin (220) is inserted into the connecting portion (120) and the discharge cover (222) is opened, the discharge cover (222) can be supported by coming into contact with the inclined surface (124). In addition, dust falling from the dust bin (220) by gravity can move along the inclined surface (124). Accordingly, dust discharged from the dust bin (220) can move along the inner surface (121) and / or the inclined surface (124) and move to the rear side of the internal space of the connecting portion (120).

[0116]

[0117] Meanwhile, the vacuum cleaner station (100) according to one embodiment of the present invention further includes a dustbin mounting portion (130). The dustbin mounting portion (130) may be formed to extend upward from the housing (110). Specifically, the dustbin mounting portion (130) may be formed to extend upward from a portion of the rear side of the housing body (111) and may be connected to the support frame (113). Accordingly, the dustbin mounting portion (130) may form the exterior of the vacuum cleaner station (100) together with the housing (110).

[0118] The dustbin mounting portion (130) includes a mounting surface (131). The mounting surface (131) is formed to extend upward from the housing body (111) and can be positioned facing at least a portion of the outer surface of the dustbin (220) of the vacuum cleaner and / or the outer surface of the main body housing (211).

[0119] The mounting surface (131) may be formed to correspond to the shape of the dustbin (220) and / or the main body housing (211). For example, when the dustbin (220) and / or the main body housing (211) are formed in a cylindrical shape, the mounting surface (131) may be formed to have the same curvature as the outer surface of the dustbin (220) and / or the main body housing (211). Through this, when the dustbin (220) is coupled to the coupling portion (120), the mounting surface (131) may surround at least a portion of the dustbin (220) and / or the main body housing (211).

[0120] With this configuration, when the vacuum cleaner (200) is mounted on the joint (120), the dustbin mounting portion (130) can stably support the vacuum cleaner (200).

[0121] Meanwhile, a spring receiving groove (131a) may be formed in the mounting surface (131). At least a portion of the spring (134) and the striker (133) may be received in the spring receiving groove (131a). At this time, the spring (134) may be compressed and extended within the spring receiving groove (131a). The spring receiving groove (131a) may be positioned facing the door button (233), which will be described later, when the cleaner (200) is connected to the connecting portion (120).

[0122] For example, the spring receiving groove (131a) may be a circular groove. In this case, a stopper may be formed to protrude along the circumferential direction on the side wall of the spring receiving groove (131a). The stopper may prevent the striker (133) from being detached.

[0123] Additionally, an exhaust port (132) may be formed on the mounting surface (131). The exhaust port (132) may be connected to an exhaust path (171) to be described later. Specifically, the exhaust port (132) may be connected to the upper end of the exhaust path (171).

[0124] The exhaust port (132) may be positioned facing the suction port door (231) described later when the cleaner (200) is connected to the coupling part (120). At this time, the exhaust port (132) may be formed to have a larger area than the suction port door (231). Through this, even if the suction port door (231) is opened and protrudes outward, the exhaust port (132) can accommodate at least a portion of the suction port door (231) and can communicate the exhaust path (171) with the internal space of the main body housing (211).

[0125] A striker (133) may be placed on the dustbin mounting portion (130). Specifically, the striker (133) may be placed on the mounting surface (131) and may be provided to protrude from the mounting surface (131) toward the vacuum cleaner (200).

[0126] The striker (133) is formed in the shape of a cylinder or a cylinder with at least one longitudinal end blocked, and the other longitudinal end can be accommodated inside a spring receiving groove (131a). At this time, a protrusion (133a) may be formed at the radial center of the one longitudinal end of the striker (133). In addition, a stopper (133b) may be protruded and formed along the circumferential direction on the outer circumferential surface of the other longitudinal end of the striker (133). In addition, the other longitudinal end of the striker (133) may be elastically supported by a spring (134). With this configuration, the striker (133) can perform a reciprocating stroke motion within the spring receiving groove (131a).

[0127] A spring (134) may be placed in the dustbin mounting portion (130). Specifically, the spring (134) may be placed in a spring receiving groove (131a) formed in the mounting surface (131).

[0128] The spring (134) can elastically support the striker (133) within the spring receiving groove (131a). For example, the spring (134) may be a coil spring. With this configuration, when an external force is applied to the striker (133), the striker (133) compresses the spring (134), and the spring (134) can apply a restoring force to the striker (133).

[0129] Accordingly, when the cleaner (200) is coupled to the cleaner station (100), the striker (133) can press the door button (233), thereby opening the suction inlet door (231).

[0130] Meanwhile, a sealer (135) may be placed on the dustbin mounting portion (130). Specifically, the sealer (135) may be placed on the mounting surface (131).

[0131] The sealer (135) can seal the space between the mounting surface (131) and the main body housing (211). The sealer (135) can be arranged to surround the exhaust port (132). For example, the sealer (135) can be arranged to surround the area where the exhaust port (132) and the striker (133) are arranged on the mounting surface (131). Through this, air discharged from the exhaust port (132) and introduced into the main body housing (211) can be prevented from leaking to the outside.

[0132] Meanwhile, depending on the embodiment, the mounting surface (131) may be formed in a sunken shape within the area surrounded by the sealer (135). Through this, a space can be secured through which the suction port door (231) can be opened outward.

[0133]

[0134] The vacuum cleaner station (100) is placed within the housing (110) and includes a dust separation unit (140) that separates dust from the air flowing in from the dust bin (220).

[0135] The dust separation unit (140) may be placed on the lower side of the coupling unit (120). The dust separation unit (140) may be placed inside the dust collection unit (150).

[0136] The dust separation unit (140) can be connected to the dust collection path (161). The dust separation unit (140) can separate dust that flows into the dust collection unit (150) through the dust collection path (161). The dust separation unit (140) can be connected to the dust collection unit (150).

[0137] For example, the dust separation unit (140) may be a cyclone capable of separating dust by cyclone flow. In addition, the dust separation unit (140) may be connected to the dust collection path unit (160). Therefore, the air and dust introduced through the dust collection path unit (160) flow spirally along the inner surface of the dust collection unit (150) and are introduced into the dust separation unit (140). In addition, the air and dust introduced into the dust separation unit (140) may separate the dust again while spirally flowing within the dust separation unit (140).

[0138] Accordingly, the dust separated through the dust separation unit (140) moves downward by gravity and is stored in the dust collection unit (150), and the air from which the dust has been separated rises and can be introduced into the exhaust passage (171).

[0139]

[0140] The vacuum cleaner station (100) is placed within a housing (110) and includes a dust collection unit (150) in which dust from a dust bin (220) is collected.

[0141] The dust collector (150) is positioned at the lower side of the coupling part (120) and can collect dust from the dust bin (220). Specifically, the dust collector (150) can be detachably coupled to the lower side of the housing body (111). For example, the dust collector (150) can be inserted and coupled between the housing body (111) and the bottom support plate (112). In addition, the dust collector (150) can be separated from the housing (110) and empty the stored dust.

[0142] The dust collection unit (150) may be in the form of a cylinder with a closed bottom. That is, the dust collection unit (150) may be a dust bin. For example, the dust collection unit (150) may be in the form of a cylinder with a closed bottom. In this case, a dust separation unit (140) may be arranged inside the dust collection unit (150).

[0143] Meanwhile, the dust collecting unit (150) may be arranged in at least a portion of the dust collecting passage (160). For example, the dust collecting unit (150) may be provided with a dust collecting passage connection pipe (162) and may be connected to the dust collecting passage (161) formed in the housing body (111). Accordingly, the internal space of the dust collecting unit (150) may be communicated with the dust collecting passage (161).

[0144] Therefore, dust that is introduced together with air through the dust collection path (161) can be separated in the dust separation unit (140) and captured in the dust collection unit (150).

[0145]

[0146] The vacuum cleaner station (100) includes a dust collection path (160). The dust collection path (160) can connect the internal space of the dust bin (220) and the dust collection part (150).

[0147] The dust collection unit (160) can be placed in the housing body (111) and the dust collection unit (150).

[0148] Specifically, an upper part of the dust collection path (160) may be placed within the housing body (111). In addition, a lower part of the dust collection path (160) may be placed in the dust collection unit (150).

[0149] For example, the dust collection path (160) may be formed in a tube shape, and a dust collection path (161) may be formed inside. For example, the upper end of the dust collection path (160) may be connected to the coupling part (120). Accordingly, the upper end of the dust collection path (161) may be communicated with the internal space of the coupling part (120). In addition, the lower end of the dust collection path (160) may be a dust collection path connecting pipe (162) provided in the dust collection unit (150). For example, the path connecting pipe (162) may be formed in a tube shape, but the discharge port through which air is discharged may be open toward the side rather than downward. Accordingly, the lower end of the dust collection path (161) may be communicated with the dust collection unit (150) and the dust separation unit (140).

[0150] Meanwhile, the dust collection path (161) may be formed in a form that is bent at least once. Specifically, the upper end of the dust collection path (161) may be formed in a form that is connected rearwardly in the internal space of the coupling portion (120) and then bent downward. In addition, the lower end of the dust collection path (161) may not be opened downward, but may be bent so that air is discharged along the circumferential direction on the inner surface of the dust collection unit (150). Through this, there is an effect of preventing the dust discharged from the dust bin (220) from flowing backward, and generating a cyclone flow in the process of being introduced into the dust collection unit (150).

[0151]

[0152] The vacuum cleaner station (100) includes an exhaust passage section (170). The exhaust passage section (170) can guide air passing through the dust collection section (150) to the suction motor (216) of the vacuum cleaner.

[0153] The exhaust duct (170) can be placed in the housing body (111) and the dustbin mounting portion (130).

[0154] Specifically, an upper portion of the exhaust passage section (170) may be placed within the dustbin mounting section (130). In addition, a lower portion of the exhaust passage section (170) may be placed within the housing body (111).

[0155] For example, the exhaust passage part (170) may be formed in a tube shape, and an exhaust passage (171) may be formed inside. For example, the upper end of the exhaust passage part (170) may be connected to the exhaust port (132). Accordingly, the upper end of the exhaust passage (171) may be in communication with the internal space of the main body housing (211) of the cleaner (200). In addition, the lower end of the exhaust passage part (170) may be a cyclone cover (172) provided at the upper end of the dust separation part (140). For example, the cyclone cover (172) may be formed so as to cover the upper end of the dust separation part (140), but a space through which air can flow may be formed inside. Accordingly, the lower end of the exhaust passage (171) may be in communication with the dust separation part (140).

[0156] Meanwhile, the exhaust path (171) may be formed in a form that is bent at least once. Specifically, the exhaust path (171) is formed in a vertical direction, and the upper end of the exhaust path (171) may be bent in a left-right direction to communicate with the exhaust port (132). In addition, the lower end of the exhaust path (171) may be bent to communicate with the internal space of the cyclone cover (172). Through this, the dust collection path (161) and the exhaust path (171) may be arranged within a limited space.

[0157] Meanwhile, the lower end of the exhaust passage (171) may be positioned higher from the ground than the lower end of the dust collection passage (161). Through this, dust may be separated from the air introduced through the dust collection passage (161) and then introduced into the exhaust passage (171).

[0158] In addition, the upper end of the exhaust path (171) can be positioned higher from the ground than the upper end of the dust collection path (161). Through this, the distance that the dust stored in the dust bin (220) falls can be shortened, thereby reducing the overall length of the path, but the height of the exhaust port (132) can be increased, thereby preventing dust from flowing into the suction motor (216).

[0159] Therefore, according to the present invention, it is possible to prevent dust from being included in the air flowing into the suction motor (216) from the dust collection unit (150), thereby preventing a failure of the suction motor (216).

[0160]

[0161] Meanwhile, FIG. 7 shows a perspective view of a cleaner according to an embodiment of the present invention, FIG. 8 shows a cross-sectional view of FIG. 7, FIG. 9 shows a cross-sectional view for explaining a state in which a connection path is open in a cleaner according to an embodiment of the present invention, and FIG. 10 shows a cross-sectional view for explaining a state in which a connection path is closed in a cleaner according to an embodiment of the present invention.

[0162] Referring to FIGS. 7 to 10, a vacuum cleaner (200) according to an embodiment of the present invention will be described as follows.

[0163] The vacuum cleaner (200) may refer to a vacuum cleaner that is manually operated by a user. For example, the vacuum cleaner (200) may refer to a handheld vacuum cleaner or a stick vacuum cleaner.

[0164] Meanwhile, in the embodiment of the present invention, the direction of the vacuum cleaner (200) can be defined based on the time when the bottom surface (lower surface) of the battery (240) is placed on the ground.

[0165] At this time, the front refers to the direction in which the dustbin (220) is placed based on the suction motor (216), and the rear may refer to the opposite direction of the front. In addition, when looking at the dustbin (220) from the suction motor (216), the direction in which it is placed on the right may be referred to as the right, and the direction in which it is placed on the left may be referred to as the left. In addition, in the 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 (240) is placed on the ground.

[0166] The vacuum cleaner (200) may include a vacuum cleaner body (210). The vacuum cleaner body (210) may include a body housing (211), a suction unit (212), a dust separation unit (213), a connection path (214), a filter (215), a suction motor (216), and a handle (217).

[0167] The main body housing (211) may form the exterior of the vacuum cleaner (200). The main body housing (211) may provide a space capable of accommodating a suction motor (216) and a filter therein. The main body housing (211) may be configured in a shape similar to a cylinder.

[0168] Specifically, a suction motor (216) may be placed inside the main body housing (211). For example, a motor housing may be placed inside the main body housing (211), and a suction motor (216) may be placed inside the motor housing.

[0169] An air intake port (211a) may be formed in the main body housing (211). External air may be introduced into the main body housing (211) through the air intake port (211a). Air introduced through the air intake port (211a) may flow within the main body housing (211) and be introduced into the suction motor (216).

[0170] When the cleaner (200) is coupled to the cleaner station (100), the air intake port (211a) can be positioned facing the exhaust port (132). In addition, when the cleaner (200) is coupled to the cleaner station (100), the air intake port (211a) can be positioned inside the sealer (135).

[0171] An exhaust port (211b) may be formed in the main body housing (211). An exhaust port (211b) may be formed on the outer circumferential surface of the main body housing (211). Air discharged from the suction motor (216) may be discharged to the outside of the main body housing (211) through the exhaust port (211b).

[0172] A control unit (211c) may be arranged in the main body housing (211). The control unit (211c) may be arranged on the outer surface of the main body housing (211). The control unit (211c) 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 (200) through the control unit (211c).

[0173]

[0174] The suction unit (212) is arranged on the lower side of the main body housing (211) and the dust bin (220), and may protrude outward from the dust bin (220). For example, the suction unit (212) may be formed in a cylindrical shape with an open interior. The suction unit (212) may be coupled to an extension pipe (250). The suction unit (212) may provide a suction path through which air containing dust may flow.

[0175] Meanwhile, in the vacuum cleaner (200) according to an embodiment of the present invention, the suction unit (212) may be formed along a direction parallel to the rotation axis of the suction motor (216). Accordingly, the flow path inside the suction unit (212) may be formed along a direction parallel to the longitudinal direction of the dust bin (220), and then bent to be connected to the dust bin (220).

[0176] The dust separation unit (213) may be equipped with one or more cyclones capable of separating dust by cyclone flow.

[0177] The dust separation unit (213) is a configuration that applies the principle of a dust collector that uses centrifugal force to separate dust sucked into the interior of the vacuum cleaner body (210) through the suction unit (212). That is, the dust separation unit (213) refers to a space where a cyclone flow that rotates along the inner surface of the dust bin (220) occurs, and the dust separation unit (213) may refer to a portion of the space inside the dust bin (220).

[0178] The dust separation unit (213) can be communicated with the suction unit (212). The dust separation unit (213) can separate dust sucked into the interior through the suction unit (212). The space inside the dust separation unit (213) can be communicated with the space inside the dust bin (220).

[0179] The cyclone flow generated in the dust separation unit (213) may be due to the suction power of the suction motor (216).

[0180] The cyclone flow generated in the dust separation unit (213) can be formed in a spiral shape along the inner circumference of the dust bin (220). That is, the air sucked in through the suction unit (212) flows in a spiral shape along the inner circumference of the dust bin (220), thereby allowing a cyclone flow to occur in the internal space of the dust separation unit (213).

[0181] The dust separation unit (213) may include a second cyclone unit that separates dust again from the air that flows around the inner circumference of the dust bin (220). That is, the second cyclone unit can filter out small dust.

[0182] At this time, the dust separation unit (213) may be positioned inside the dust bin (220). The dust separation unit (213) may be positioned in front of the suction motor (216).

[0183] The second cyclone section may include a plurality of cyclone bodies arranged in parallel. Therefore, the cyclone flow generated in the second cyclone section may be formed inside the cyclone bodies.

[0184] The axis of the cyclone flow generated in the dust separation unit (213) can be arranged parallel to the rotation axis of the suction motor (216).

[0185] The connecting passage (214) is arranged between the dust separation unit (213) and the suction motor (216), and can guide air passing through the dust separation unit (213) to the suction motor (216).

[0186] Meanwhile, a filter (215) may be placed on the connecting passage (214). The filter (215) may filter the air that passes through the dust separation unit (213) and flows into the suction motor (216). For example, the filter (215) may be a pre-filter. This may prevent foreign substances from flowing into the suction motor (216) and causing damage to the suction motor (216).

[0187] The suction motor (216) can generate a suction force to suck in air. The suction motor (216) can be accommodated within the main body housing (211). The suction motor (216) can generate a suction force by rotation. For example, the suction motor (216) can be provided in a shape similar to a cylinder.

[0188] At this time, cyclone flow may be generated by the suction force of the suction motor (216).

[0189] Specifically, when the suction motor (216) is operated, the air sucked through the suction unit (212) by the suction force of the suction motor (216) can generate a cyclone flow in the dust separation unit (213).

[0190] Meanwhile, a filter may be placed radially outside the suction motor (216). The filter may be a HEPA filter. Accordingly, it is possible to prevent foreign substances from being included in the air discharged from the suction motor (216).

[0191] The handle (217) can be gripped by the user. For example, the handle (217) may be formed in a cylindrical shape. Alternatively, the handle (217) may be formed in a curved cylindrical shape. The handle (217) may be positioned at a predetermined angle with respect to the main body housing (211), the suction motor (216), or the dust separation unit (213).

[0192] The handle (217) is formed in a pillar shape so that the user can hold it, the upper part of the handle (217) can be connected to the main body housing (211), and the lower part of the handle (217) can be connected to the battery coupling part to which the battery (240) is coupled.

[0193]

[0194] The vacuum cleaner (200) may include a dust bin (220). The dust bin (220) may be connected to a suction unit (212). A dust separation unit (213) may be arranged inside the dust bin (220). The dust bin (220) may store dust separated from the dust separation unit (213).

[0195] The dustbin (220) may include a dustbin body (221), a discharge cover (222), a dustbin compression lever, and a compressor.

[0196] The dustbin body (221) can provide a space for storing dust separated from the dust separation unit (213). For example, the dustbin body (221) can be formed in a shape similar to a cylinder.

[0197] Meanwhile, in the present embodiment, the longitudinal direction of the dustbin body (221) may be arranged parallel to the rotation axis of the suction motor (216). In addition, the longitudinal direction of the dustbin body (221) may be arranged parallel to the longitudinal direction of the suction unit (212).

[0198] The front surface of the dustbin body (221) can be opened. A hinge part (221a) and a cover opening lever (221b) can be arranged on the dustbin body (221). The hinge part (221a) can be arranged on the front lower side of the dustbin body (221). The dustbin body (221) and the discharge cover (222) can be rotatably coupled through the hinge part (221a). The hinge part (221a) can provide a rotation axis of the discharge cover (222) with respect to the dustbin body (221).

[0199] The dustbin (220) may include a discharge cover (222). The discharge cover (222) may be positioned at the front end of the dustbin (220).

[0200] The discharge cover (222) may be provided to open and close one longitudinal end of the dustbin body (221). Specifically, the discharge cover (222) may selectively open and close the front end of the dustbin (220) that opens forward.

[0201] The discharge cover (222) can be formed to block the front surface of the dustbin body (221). The discharge cover (222) can rotate forward based on the hinge portion (221a).

[0202] The discharge cover (222) can be connected to the dustbin body (221) through a hook connection. Meanwhile, the discharge cover (222) can be separated from the dustbin body (221) through a cover opening lever (221b). The cover opening lever (221b) can be positioned at the front upper side of the dustbin body (221). When an external force is applied, the cover opening lever (221b) can release the hook connection between the discharge cover (222) and the dustbin body (221).

[0203] The dustbin (220) may include a dustbin compression lever. The dustbin compression lever may be disposed outside the dustbin (220). The dustbin compression lever may be disposed outside the dustbin (220) to move forward and backward. The dustbin compression lever may be connected to a compressor. When the dustbin compression lever moves forward due to an external force, the compressor may also move forward. This may provide convenience to the user. The compressor 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 backward.

[0204] The compressor can be placed inside the dustbin body (221). The compressor can move in the internal space of the dustbin body (221). Specifically, the compressor can move back and forth inside the dustbin body (221). Through this, the compressor can compress the dust inside the dustbin body (221) forward. In addition, when the discharge cover (222) is separated from the dustbin body (221) and the front of the dustbin (220) is opened, the compressor can move from the rear to the front of the dustbin (220) to remove foreign substances such as residual dust inside the dustbin (220). Through this, the suction power of the vacuum cleaner can be improved by preventing residual dust from remaining inside the dustbin (220). In addition, by preventing residual dust from remaining inside the dustbin (220), an unpleasant odor caused by the residual dust can be eliminated.

[0205] The vacuum cleaner (200) may include a battery coupling portion. A battery (240) may be coupled to the battery coupling portion. The battery coupling portion may be positioned on the lower side of the handle (217).

[0206] The battery (240) can be removed through the battery connector.

[0207]

[0208] A cleaner (200) according to an embodiment of the present invention includes a flow conversion unit (230). The flow conversion unit (230) can change the path of air flowing into the suction motor (216) as the cleaner (200) is coupled to the cleaner station (100).

[0209] The euro conversion unit (230) includes an intake door (231), a euro conversion valve (232), a door button (233), and a euro conversion frame (234).

[0210] The intake door (231) can open and close the air intake (211a). The intake door (231) can be placed in the main body housing (211). The intake door (231) can be placed so as to cover the air intake (211a). That is, when the intake door (231) is closed, the air intake (211a) can be blocked to form an exterior that is connected to the main body housing (211). Meanwhile, when the intake door (231) is opened, the intake door (231) can move outward from the main body housing (211) to expose the air intake (211a) to the outside.

[0211] When the cleaner (200) is coupled to the cleaner station (100), the suction door (231) can be positioned facing the exhaust port (132). In addition, when the cleaner (200) is coupled to the cleaner station (100), the suction door (231) can be positioned inside the sealer (135).

[0212] Meanwhile, the suction inlet door (231) can be opened when the cleaner (200) is coupled to the cleaner station (100).

[0213] Accordingly, when the cleaner (200) is coupled to the cleaner station (100), the intake door (231) can be moved toward the exhaust port (132) of the cleaner station (100). Then, the exhaust port (132) and the air intake port (211a) can be communicated with each other. Consequently, the exhaust path (171) can be communicated with the internal space of the main body housing (211) through the exhaust port (132) and the air intake port (211a).

[0214] The flow diversion valve (232) can open and close the connecting flow path (214). The flow diversion valve (232) can be opened and closed in conjunction with the intake door (231). Specifically, the flow diversion valve (232) can close the connecting flow path (214) when the intake door (231) is opened. In addition, the flow diversion valve (232) can open the connecting flow path (214) when the intake door (231) is closed.

[0215] The flow diversion valve (232) may be positioned between the dust separation unit (213) and the suction motor (216). The flow diversion valve (232) may move between the dust separation unit (213) and the suction motor (216) to open and close the connection flow path (214). For example, when the flow diversion valve (232) moves toward the dust separation unit (213), the connection flow path (214) may be opened, and when the flow diversion valve (232) moves toward the suction motor (216), the connection flow path (214) may be closed.

[0216] The door button (233) is exposed to the main body housing (211) and can open the intake door (231) when an external force is applied. The door button (233) can be placed on the main body housing (211). At this time, the door button (233) can be placed adjacent to the intake door (231). In addition, the door button (233) can be placed adjacent to the air intake (211a).

[0217] The door button (233) can be moved inside the main body housing (211) when an external force is applied. The door button (233) can be rotated by pressing the euro conversion frame (234). For example, the door button (233) can be formed in a pin shape, but the outer end can be formed in a circular shape.

[0218] The euro conversion frame (234) can open and close the intake door (231) and the euro conversion valve (232) by receiving rotational force from the door button (233).

[0219] The euro conversion frame (234) can be placed within the main body housing (211). The euro conversion frame (234) can be placed so as to penetrate from the connection euro (214) to the air intake (211a) within the main body housing (211).

[0220] The euro conversion frame (234) includes a frame body (234a), a door connection portion (234b), a valve connection portion (234c), a button connection portion (234d), and a rotation shaft (234e). At this time, the frame body (234a) may have a door connection portion (234b) extended on one longitudinal side, a valve connection portion (234c) extended on the other longitudinal side, and a button connection portion (234d) extended between the door connection portion (234b) and the valve connection portion (234c). The rotation shaft (234e) may be arranged on the button connection portion (234d).

[0221] The door connecting portion (234b) can be connected to the intake door (231). The door connecting portion (234b) can be formed by extending and bending from the frame body (234a). The door connecting portion (234b) can be formed by extending and bending from the frame body (234a) to the outside of the main body housing (211).

[0222] The valve connection (234c) can be connected to the euro switching valve (232). The valve connection (234c) can be formed by extending and bending from the frame body (234a). The valve connection (234c) can be formed by extending and bending from the frame body (234a) toward the dust separator (213).

[0223] The button connection portion (234d) can be coupled with the door button (233). The button connection portion (234d) can be formed by branching off from the frame body (234a) and extending. At this time, the button connection portion (234d) can have a spring arranged on the back surface of the portion coupled with the door button (233). Accordingly, when the external force applied from the door button (233) is released, the button can be returned to its original position by the restoring force of the spring.

[0224] The rotation shaft (234e) can be placed on the button connection portion (234d). The rotation shaft (234e) can be coupled to the main body housing (211). When an external force is applied to the door button (233), the flow conversion frame (234) can rotate around the rotation shaft (234e). Accordingly, the intake door (231) and the flow conversion valve (232) can selectively open the air intake (211a) and the connecting flow path (214).

[0225]

[0226] The vacuum cleaner (200) may include a battery (240).

[0227] For example, the battery (240) can be detachably coupled to the vacuum cleaner coupling part.

[0228] The battery (240) stores electric energy and can supply power to each component including the suction motor (216) of the vacuum cleaner (200). The battery (240) can be placed at the bottom of the handle (217).

[0229] The vacuum cleaner (200) may include an extension pipe (250). The extension pipe (250) may be connected to a vacuum cleaner nozzle (260). The extension pipe (250) may be connected to a vacuum cleaner body (210). The extension pipe (250) may be connected to a suction part (212) of the vacuum cleaner body (210). The extension pipe (250) may be formed in a cylindrical shape.

[0230] The vacuum cleaner body (210) can generate suction force through a suction motor (216) and provide suction force to the vacuum cleaner nozzle (260) through an extension tube (250). External dust can enter the vacuum cleaner body (210) through the vacuum cleaner nozzle (260) and the extension tube (250).

[0231] The vacuum cleaner (200) may include a vacuum cleaner nozzle (260). The vacuum cleaner nozzle (260) may be connected to an extension tube (250). Accordingly, external air may be drawn into the vacuum cleaner body (210) through the vacuum cleaner nozzle (260) and the extension tube (250) by the suction force generated in the vacuum cleaner body (210).

[0232]

[0233] Meanwhile, FIG. 11 illustrates a cross-sectional view of a vacuum cleaner system according to an embodiment of the present invention, and FIG. 12 illustrates a cross-sectional view for explaining the flow of air in a vacuum cleaner system according to an embodiment of the present invention.

[0234] Referring to FIGS. 9 to 12, the flow of air flowing through the vacuum cleaner system (1) according to an embodiment of the present invention will be described.

[0235] First, when the cleaner (200) is not connected to the cleaner station (100), the connection path (214) is open and the air intake port (211a) is closed.

[0236] In this case, when the suction motor (216) is operated, external air can be drawn into the dust bin (220) through the vacuum cleaner nozzle (260), the extension pipe (250), and the suction unit (212). The air drawn into the dust bin (220) can have dust separated by the dust separation unit (213). The air that has passed through the dust separation unit (213) can flow toward the suction motor (216) through the connection path (214) after the dust is filtered by the filter (215). The air discharged from the suction motor (216) can be discharged to the outside through the HEPA filter and the exhaust port (211b).

[0237] Meanwhile, when the vacuum cleaner (200) is coupled to the vacuum cleaner station (100), the dust bin (220) is inserted into the inner surface (121) of the coupling portion (120). At this time, the cover opening lever (221b) is pressed by the push portion (122), and the discharge cover (222) is opened.

[0238] In addition, the main body housing (211) is positioned to face the mounting surface (131), and the striker (133) presses the door button (233). Accordingly, the euro conversion frame (234) rotates, opening the intake door (231), and the euro conversion valve (232) blocks the connecting euro (214).

[0239] Therefore, when the suction motor (216) is operated, the suction force of the suction motor (216) can be applied to the exhaust path (171) and dust collection path (161) of the cleaner station (100).

[0240] Therefore, when the suction motor (216) is operated, external air can be introduced into the dust bin (220) through the cleaner nozzle (260), the extension pipe (250), and the suction unit (212). The air introduced into the dust bin (220) can flow inside the dust bin (220) and clean the inside of the dust bin (220). Thereafter, the air containing dust can be introduced into the internal space of the coupling unit (120) and flow along the dust collection path (161) to flow through the dust separation unit (140) of the cleaner station (100). In this process, the dust contained in the air is separated, the dust is stored in the dust collection unit (150), and the air can flow upward along the exhaust path (171). Air flowing along the exhaust path (171) can flow toward the suction motor (216) after passing through the exhaust port (132) and then through the air intake port (211a). Air discharged from the suction motor (216) can be discharged to the outside through the HEPA filter and the exhaust port (211b).
