Description

vacuum cleaner

[0001] The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner that prevents non-installation of a filter unit.

[0002] A vacuum cleaner is a device that cleans by sucking up dust or foreign substances in the area to be cleaned or wiping them away.

[0003] A vacuum cleaner includes an impeller and a motor that rotates the impeller to provide the driving force to suck up dust. The vacuum cleaner generates suction by exhausting internal air through the motor's action, thereby lowering internal pressure. This suction force then sucks in dust and other foreign substances from the cleaning surface along with the outside air through the suction device. The outside air and the sucked foreign substances can then be removed by a dust collector or other device.

[0004] Depending on their shape, vacuum cleaners can be classified into canister type vacuum cleaners, upright type vacuum cleaners, handheld vacuum cleaners, and stick type vacuum cleaners.

[0005] Meanwhile, vacuum cleaners are equipped with pre-filters and HEPA filters to separate dust from the air they suck in. However, if the dust accumulated on the filter is not cleaned due to long-term use of the filter, there is a limit to how well the suction performance can be reduced.

[0006] Korean Patent No. KR 10-2584210B discloses a detachable pre-filter (29). The pre-filter (29) is mounted on the upper motor housing (26), and when the filter mechanism (50) is separated from the main body (2), the pre-filter (29) becomes detachable. The user can remove the pre-filter (29) from the main body (2) for cleaning or replacement.

[0007] However, the above cleaner has a limitation in that the filter mechanism (50) can be installed in the main body (2) without the pre-filter (29) being assembled, and the user cannot recognize that the pre-filter (29) is not installed.

[0008] In addition, in order to improve dust separation performance, a sealing structure is required between the parts installed inside the vacuum cleaner. However, as various parts such as filters are installed inside the vacuum cleaner and sealing structures are installed for each part, the number of parts increases, which increases costs and has limitations in that the structure becomes complicated.

[0009] The present invention was created to improve the problems of conventional vacuum cleaners as described above, and the purpose of the present invention is to provide a vacuum cleaner that can easily be recognized by a user when a pre-filter is not installed and can prevent the vacuum cleaner from operating when the pre-filter is not installed.

[0010] In addition, the purpose is to provide a cleaner that can improve the suction power of the cleaner by shortening the air flow path and improve the efficiency of the duct by having a pre-filter structure that is suitable for the duct layout.

[0011] In addition, the purpose is to provide a cleaner that reduces the number of parts by integrating two sealing members required for a euro configuration into a sealing member of a single pre-filter, thereby reducing the overall weight and providing a simple and slim structure.

[0012] In addition, the purpose is to provide a vacuum cleaner that improves assembly by eliminating the need for a separate installation structure for installing a pre-filter and a sealing member and by being fixed by the fastening of the dust separation unit and the motor housing.

[0013] In order to achieve the above-mentioned purpose, the vacuum cleaner according to the present invention improves the efficiency of the filter and allows the user to easily recognize when the filter part is not installed.

[0014] Specifically, a vacuum cleaner according to the present invention comprises a suction unit to which an extension pipe is connected and a suction path through which air can flow is formed, a dust separation unit having at least one cyclone unit, a suction motor providing air flow force, a motor housing in which the suction motor is accommodated and an air discharge port through which air passing through the suction motor is discharged, and a filter unit disposed between the cyclone unit and the suction motor to filter the suctioned air, wherein the motor housing includes a filter mounting portion to which the dust separation portion is fastened, and the filter unit can be fixed between the filter mounting portion and the dust separation portion by fastening the filter mounting portion and the dust separation portion.

[0015] In addition, the filter unit may be provided with a sealing member inserted between the filter mounting unit and the dust separation unit.

[0016] In addition, the filter unit includes a filter net formed to surround at least a portion of the motor housing and open upward, a lower frame disposed below the filter net, and an upper frame disposed above the filter net and having the sealing member, and the filter unit can be disposed to be spaced apart from the inner surface of the dust separation unit.

[0017] Through this, the assembly of the filter unit and the dust separation unit can be improved.

[0018] At this time, the upper frame may be arranged to be spaced apart from the filter mounting portion in the vertical direction. Accordingly, the sealing member is arranged to seal between the upper frame and the filter mounting portion.

[0019] Additionally, the lower frame can be formed by alternately arranging the peaks and valleys along the circumference.

[0020] Specifically, the sealing member may include a body integrally provided with the filter unit, a first support member provided at one end of the body to support the filter mounting portion, and a second support member provided at the other end of the body to support the dust separation portion.

[0021] At this time, the sealing member may be formed such that the first support portion protrudes from one end of the body toward the filter mounting portion, but may be formed such that the first support portion protrudes toward the other end of the body.

[0022] With this configuration, the sealing member can seal the outer space of the joint portion, the space between the joint portion and the filter portion, and the inner space of the filter portion. That is, only one sealing member is provided to function as two sealing members, thereby reducing the number of parts.

[0023] In addition, the dust separation unit can be rotated and fastened to the filter mounting portion when supported by the sealing member while moving in the axial direction.

[0024] Specifically, the dust separation unit may have a fastening projection formed on an outer surface facing the filter mounting portion, and the filter mounting portion may have a fastening groove formed along a circumferential direction into which the fastening projection is inserted, and a stopper provided on the inner side of the fastening groove and fastened to a catch groove of the fastening projection to fix the fastening projection to the fastening groove.

[0025] The dust separation unit and the filter mounting unit may be spaced apart from each other along the axial direction of the suction motor. Accordingly, if the sealing member is not positioned in the spaced apart space between the dust separation unit and the filter mounting unit, the dust separation unit will not be stably supported, so that the user can easily recognize whether the filter unit is not mounted.

[0026] In addition, a vacuum cleaner according to the present invention may include a suction unit having an extension pipe connected thereto and a suction path through which air can flow, a dust separation unit having at least one cyclone unit, a suction motor providing air flow force, a main body housing having the suction unit on one side and having the dust separation unit and the suction motor disposed therein, a filter unit disposed between the cyclone unit and the suction motor to filter air passing through the cyclone unit, and a sealing member sealing an outer space of the dust separation unit, a space between the dust separation unit and the filter unit, and an inner space of the filter unit.

[0027] Through this, a sealing member is provided to seal the outer space of the dust separation unit, the space between the dust separation unit and the filter unit, and the inner space of the filter unit, thereby ensuring a secure seal, and thereby improving the performance of the dust separation unit and the filter unit, thereby enhancing dust absorption. In addition, the provision of a sealing member prevents dust leakage and has the effect of preventing dust from being discharged to the outside.

[0028] Here, the dust separation unit is fastened to the main body housing, and the sealing member is inserted and fixed between the main body housing and the dust separation unit, and can be integrally provided with the filter unit.

[0029] Through this, the sealing member can support the dust separation unit and the motor housing in a state of being connected to each other.

[0030] Additionally, the dust separation unit and the filter mounting unit may be spaced apart from each other along the length direction of the main body housing with the sealing member interposed therebetween.

[0031] As described above, the vacuum cleaner according to the present invention has the effect of allowing a user to easily recognize when a pre-filter is not installed, and preventing the vacuum cleaner from operating when the pre-filter is not installed.

[0032] In addition, as the pre-filter is placed between the suction motor and the cyclone, the air flow path is shortened and the suction power of the cleaner is improved, and as the pre-filter structure is provided to match the flow path arrangement, the flow path efficiency is improved.

[0033] In addition, the two sealing members required for the euro configuration can be integrated into one sealing member of the pre-filter, thereby reducing the number of parts and reducing weight, and providing a simple and slim structure.

[0034] In addition, a separate installation structure for installing the pre-filter and sealing member is unnecessary, and the assembly is improved and convenience is provided to the user as the dust separation unit and the motor housing are fixed together.

[0050] Meanwhile, in this specification, “floor surface” may be understood to mean not only the floor surface of a living room or room, but also a clean surface such as a carpet.

[0051] Referring to FIGS. 1 to 4, a cleaner (1) according to one embodiment of the present invention may include a cleaner body (100) having a fan driving unit (140) for generating suction force, a cleaner nozzle (300) connected to the cleaner body (100) for sucking air and foreign substances from the floor, and an extension pipe (200) connecting the cleaner body (100) and the cleaner nozzle (300).

[0052] The structure of the vacuum cleaner body (100) is described as follows.

[0053] First, the structure of the vacuum cleaner (1) will be described with reference to FIGS. 1 to 3 as follows.

[0054] A vacuum cleaner (1) may refer to a vacuum cleaner that is manually operated by a user. For example, the vacuum cleaner (1) may refer to a handheld vacuum cleaner or a stick vacuum cleaner.

[0055] Meanwhile, in one embodiment of the present invention, the direction of the vacuum cleaner (1) can be defined based on the time when the bottom surface (lower surface) of the dust bin (170) and the battery housing (180) are placed on the ground.

[0056] At this time, the front may refer to the direction in which the suction unit (120) is arranged based on the suction motor (142), and the rear may refer to the direction in which the handle (160) is arranged based on the suction motor (142). In addition, when looking at the suction unit (120) from the suction motor (142), the direction in which it is arranged on the right may be referred to as the right, and the direction in which it is arranged on the left may be referred to as the left. In addition, in one embodiment of the present invention, the upper and lower sides may be defined along the direction perpendicular to the ground when the bottom surface (lower surface) of the dust bin (170) and the battery housing (180) are placed on the ground.

[0057] The vacuum cleaner (1) may include a vacuum cleaner body (100). The vacuum cleaner body (100) may include a body housing (110), a suction unit (120), a dust separation unit (130), a fan driving unit (140), an air exhaust cover (180), and a handle (160).

[0058] The main body housing (110) may form the exterior of the vacuum cleaner (1). The main body housing (110) may provide a space capable of accommodating a fan drive unit (140) and a filter unit (145) therein. For example, the main body housing (110) may be configured in a shape similar to a cylinder.

[0059] The suction unit (120) may protrude outwardly from the main body housing (110). For example, the suction unit (120) may be formed in a cylindrical shape with an open interior. The suction unit (120) may be coupled to an extension pipe (200). Accordingly, the suction unit (120) may provide a path (hereinafter, referred to as a "suction path") through which air containing dust may flow.

[0060] Meanwhile, in this embodiment, a virtual line penetrating the interior of a suction part (120) having a cylindrical shape can be formed.

[0061] The dust separation unit (130) may be communicated with the suction unit (120). The dust separation unit (130) may separate dust sucked into the interior through the suction unit (120). The internal space of the dust separation unit (130) may be communicated with the internal space of the dust bin (170).

[0062] For example, the dust separation unit (130) may be equipped with at least one cyclone unit (131) capable of separating dust by cyclone flow. In addition, the space inside the dust separation unit (130) may be connected to the suction path. Therefore, the air and dust sucked through the suction unit (120) flow in a spiral manner along the inner surface of the dust separation unit (130). Therefore, a cyclone flow may occur in the inner space of the dust separation unit (130).

[0063] The dust separation unit (130) is connected to the suction unit (120) and is configured to apply the principle of a dust collector that utilizes centrifugal force to separate dust sucked into the interior of the vacuum cleaner body (100) through the suction unit (120).

[0064] The dust separation unit (130) may further include a secondary cyclone that separates dust again from the air discharged from the cyclone. At this time, the secondary cyclone may be positioned inside the cyclone unit (131) so as to minimize the size of the dust separation unit. The secondary cyclone may include a plurality of cyclone bodies arranged in parallel. The air discharged from the cyclone unit may be divided and passed through the plurality of cyclone bodies.

[0065] At this time, the axis of the cyclone flow of the secondary cyclone can also extend in the vertical direction, and the axis of the cyclone flow of the cyclone section and the axis of the cyclone flow of the secondary cyclone can form a coaxial line in the vertical direction, which can be collectively referred to as the axis of the cyclone flow of the dust separation section (130).

[0066] Meanwhile, the cyclone section (131) of the dust separation section (130) may be surrounded by a mesh net. The mesh net may serve to prevent relatively large foreign substances contained in the air passing through the suction section (120) from entering the dust separation section (130). That is, the mesh net may be formed in a cylindrical shape, and a plurality of holes may be formed along the outer circumference.

[0067] In addition, the dust separation unit (130) may have a coupling unit (132) that is fastened to the main body housing (110). Specifically, the coupling unit (132) is formed by protruding the upper edge of the cyclone unit (131), and at least a part of the suction motor (142) may be disposed inside. In addition, the motor receiving unit (151) of the motor housing (150) may be disposed inside the coupling unit (132). In addition, the coupling unit (132) may be disposed inside the filter mounting unit (152) of the motor housing (150), and the upper portion may be fastened to the filter mounting unit (152). For example, the coupling unit (132) may be formed in a hollow cylindrical shape, and the lower portion may be integrally formed with the cyclone unit (131), and the upper portion may support the motor housing (150) and be fixed to the motor housing (150). Additionally, the connecting portion (132) is formed so that the diameter becomes smaller as it goes toward the bottom, and the diameter of the lower portion can be formed smaller than the diameter of the upper portion.

[0068] A fan drive unit (140) may be positioned on a path and generate a fluid force to move air within the path. This fan drive unit (140) may include a suction motor (142) and a motor housing (150).

[0069] The suction motor (142) can generate a suction force to suck in air. The suction motor (142) can include a motor shaft and an impeller that rotates according to the rotation of the motor shaft. Accordingly, the air flow force can be generated according to the rotation of the impeller. As a result, the suction motor (142) can generate a suction force by rotation.

[0070] The suction motor (142) may include, for example, a ring-shaped stator, a shaft penetrating the center of the stator, and a rotor that is mounted on the shaft and generates rotational force by the stator. Meanwhile, in the present embodiment, the suction motor (142) uses a brushless direct current motor (BLDC motor), but is not limited thereto, and various types of motors may be applied.

[0071] The motor housing (150) may include a motor receiving portion (151) that receives a suction motor (142), and a filter mounting portion (152) that is arranged to surround the motor receiving portion (151) and to which a filter portion (145) and a coupling portion (132) are fixed. In addition, the motor housing (150) is provided to guide air by installing the suction motor (142) inside the main body housing (110), and may be integrally provided with the main body housing (110) or coupled to the main body housing (110).

[0072] The motor housing (151) can support a bearing installed at the bottom or top of the suction motor (142). The side wall of the motor housing (151) is formed in a cylindrical hollow shape, and the stator of the suction motor (142) can be fixed to the inner surface of the side wall. In addition, when the suction motor (142) is installed and accommodated in the motor housing (151), a structure for supporting the bearing can be provided at the bottom or top of the motor housing (151). In addition, although not shown, a component for generating air flow and a diffuser for dispersing the generated air flow can be further provided at the bottom or top of the motor housing (151).

[0073] Meanwhile, an air outlet (147) may be formed on the upper or lower surface of the motor receiving portion (151). For example, the air outlet (147) may be formed in the shape of a hole in the center of the lower surface of the motor receiving portion (151). The air outlet (147) may be formed to be open toward the cyclone portion (131). For example, the air outlet (147) may be arranged to face the outlet (131a) of the cyclone portion (131) with the filter portion (145) interposed therebetween.

[0074] Additionally, an air discharge port (147) may be formed on one side of the motor receiving portion (151). For example, the air discharge port (147) may be provided in the form of a hole formed by penetrating the outer and inner surfaces of the motor receiving portion (151). The air discharge port (147) discharges air that has passed through the fan driving portion (140), and a plurality of air discharge ports may be provided along the periphery of the motor receiving portion (151).

[0075] The air exhaust cover (180) may be arranged on one axial side of the main body housing (110). The air exhaust cover (180) may be provided so as to be able to open and close the internal space of the main body housing (110). For example, the air exhaust cover (180) may be hinge-coupled to the main body housing (110).

[0076] A display unit (not shown) may be placed on the air exhaust cover (180). For example, a display unit (not shown) may be placed on the upper surface of the air exhaust cover (180).

[0077] A printed circuit board (not shown) for controlling a display unit (not shown) may be provided inside the air exhaust cover (180).

[0078] An exhaust port (181) for discharging air sucked in by the suction force of the suction motor (142) may be formed in the air discharge cover (180).

[0079] A flow guide may be arranged in the air exhaust cover (180). The flow guide may guide the flow of air discharged through the exhaust port (181).

[0080] Meanwhile, a path may be formed within the main body housing (110) to discharge air flowing within the dust bin (170). Specifically, the path may include a path that guides air to flow from the dust separation unit (130) to the suction motor (142), and a path that guides air passing through the suction motor (142) to flow to the exhaust port (181).

[0081] And, a filter unit (145) may be arranged on a path connecting the suction motor (142) in the dust separation unit (130), and a HEPA filter (183) may be arranged on a path connecting the exhaust port (181) in the suction motor (142). The filter unit (145) may mean a pre-filter. The filter unit (145) may mean a filter that filters out relatively large foreign substances (dust) such as fur, lint, and hair. And, the HEPA filter (183) may mean a HEPA filter. The HEPA filter (183) may mean a filter that purifies relatively small-sized fine dust.

[0082] Meanwhile, in the cleaner (1) according to one embodiment of the present invention, the filter unit (145) may be arranged between the suction motor (142) and the cyclone unit (131). Specifically, the filter unit (145) may be formed to surround at least a portion of the suction motor (142) and may be arranged between the air intake port (146) and the discharge port (131a) of the cyclone unit (131). With this configuration, the path along which air flows can be minimized. In addition, the area through which air passes through the filter unit (145) during the flow of air can be increased. Therefore, according to the present invention, there is an advantage in that the effect of filtering foreign substances can be maximized while minimizing flow loss.

[0083] The structure and arrangement of the filter unit (145) will be described later.

[0084] The handle (160) can be held by the user. The handle (160) can be positioned at the rear of the suction motor (142). For example, the handle (160) can be formed in a shape similar to a cylinder. Alternatively, the handle (160) can be formed in a curved cylinder shape. The handle (160) can be positioned at a predetermined angle with respect to the main body housing (110), the suction motor (142), or the dust separation unit (130).

[0085] The handle (160) may include a grip portion (161) formed in a pillar shape so that a user can grip it, a first extension portion (162) connected to one longitudinal (axial) end of the grip portion (161) and formed to extend toward the suction motor (142), and a second extension portion (163) connected to the other longitudinal (axial) end of the grip portion (161) and formed to extend toward the dust bin (170).

[0086] The upper surface of the handle (160) may form a portion of the appearance of the upper surface of the vacuum cleaner (1). This prevents the components of the vacuum cleaner (1) from coming into contact with the user's arm when the user holds the handle (160).

[0087] The first extension portion (162) may extend from the grip portion toward the main body housing (110) or the suction motor (142). At least a portion of the first extension portion (162) may extend in a horizontal direction.

[0088] The second extension portion (163) may extend from the grip portion toward the dust bin (170). At least a portion of the second extension portion (163) may extend in a horizontal direction.

[0089] A control unit may be placed on the handle (160). The control unit may be placed on a slope formed in the upper area of ​​the handle (160). A user may input an operation or stop command for the cleaner (1) through the control unit.

[0090] The vacuum cleaner (1) may include a dust bin (170). The dust bin (170) may be connected to a dust separation unit (130). The dust bin (170) may store dust separated from the dust separation unit (130).

[0091] The dustbin (170) may include a dustbin body (171), a discharge cover (172), a dustbin compression lever (174), and a compressor.

[0092] The dustbin body (171) can provide a space for storing dust separated from the dust separation unit (130). For example, the dustbin body (171) can be formed in a shape similar to a cylinder.

[0093] The lower surface (bottom surface) of the dustbin body (171) may be partially open. In addition, a lower extension portion may be formed on the lower surface (bottom surface) of the dustbin body (171). The lower extension portion may be formed to block a portion of the lower surface of the dustbin body (171).

[0094] The dustbin (170) may include a discharge cover (172). The discharge cover (172) may be placed on the lower surface of the dustbin (170).

[0095] The discharge cover (172) may be provided to open and close one end in the longitudinal direction of the dustbin body (171). Specifically, the discharge cover (172) may selectively open and close the lower part of the dustbin (170) that opens downward.

[0096] The discharge cover (172) may include a cover body and a hinge part. The cover body may be formed to block a portion of the lower surface of the dustbin body. The cover body may rotate downward based on the hinge part. The hinge part may be arranged adjacent to the battery housing (180). A torsion spring may be provided in the hinge part. Therefore, when the discharge cover (172) is separated from the dustbin body (171), the cover body may be supported in a state in which it is rotated by a predetermined angle or more about the hinge part as an axis in the dustbin body (171) by the elastic force of the torsion spring.

[0097] The discharge cover (172) can be coupled to the dust bin (170) through a hook connection. Meanwhile, the discharge cover (172) can be separated from the dust bin (170) through a coupling lever. The coupling lever can be arranged at the front of the dust bin. Specifically, the coupling lever can be arranged on the outer surface of the front side of the dust bin (170). When an external force is applied, the coupling lever can elastically deform a hook extended from the cover body to release the hook connection between the cover body and the dust bin body (171).

[0098] When the discharge cover (172) is closed, the lower surface of the dust bin (170) may be blocked (sealed) by the discharge cover (172) and the lower extension.

[0099] The dustbin (170) may include a dustbin compression lever (174). The dustbin compression lever (174) may be disposed outside the dustbin (170) or the dust separation unit (130). The dustbin compression lever (174) may be disposed outside the dustbin (170) or the dust separation unit (130) so as to move up and down. The dustbin compression lever (174) may be connected to a compressor. When the dustbin compression lever (174) moves downward due to an external force, the compressor also moves downward and may compress an elastic member disposed inside.

[0100] In addition, when the discharge cover (172) is separated from the dustbin body (171) and the lower part of the dustbin body (171) is opened, the compressor can move from the upper part to the lower part of the dustbin (170) to remove foreign substances such as residual dust inside the dustbin body (171).

[0101] Through this, the suction power of the vacuum cleaner can be improved by preventing residual dust from remaining in the dust bin (170). In addition, by preventing residual dust from remaining in the dust bin (170), the unpleasant odor caused by the residue can be eliminated.

[0102] The vacuum cleaner (1) may include a battery housing (191). The battery housing (191) may accommodate a battery (190). The battery housing (191) may be positioned at the lower side of the handle (160). For example, the battery housing (191) may have a hexahedral shape with an open bottom. The rear of the battery housing (191) may be connected to the handle (160).

[0103] The vacuum cleaner (1) may include a battery (190). For example, the battery (190) may be detachably coupled to the vacuum cleaner (1). The battery (190) may be detachably coupled to a battery housing (191). For example, the battery (190) may be inserted into the interior of the battery housing (191) from the lower portion of the battery housing (191). With such a configuration, the portability of the vacuum cleaner (1) may be improved.

[0104] In contrast, the battery (190) may be integrally provided inside the battery housing (191). In this case, the lower surface of the battery (190) is not exposed to the outside.

[0105] The battery (190) can supply power to the suction motor (142) of the vacuum cleaner (1). The battery (190) can be placed at the bottom of the handle (160). The battery (190) can be placed at the rear of the dust bin (170).

[0106] According to an embodiment, when the battery (190) is coupled to the battery housing (191), the battery (190) can be replaced, the battery (190) can be easily replaced, and the cooling performance of the battery (190) can be improved.

[0107] Meanwhile, when the battery (190) is integrally fixed to the battery housing (180), the structure for attaching and detaching the battery (190) and the battery housing (180) can be reduced, so the overall size of the vacuum cleaner (1) can be reduced and its weight can be reduced.

[0108] The vacuum cleaner (1) may include an extension pipe (200). The extension pipe (200) may be connected to a vacuum cleaner nozzle (300). The extension pipe (200) may be connected to a vacuum cleaner body (100). The extension pipe (200) may be connected to a suction part (120) of the vacuum cleaner body (100). The extension pipe (200) may be formed in a long cylindrical shape.

[0109] The vacuum cleaner body (100) can be connected to an extension tube (200). The vacuum cleaner body (100) can be connected to a vacuum cleaner nozzle (300) through the extension tube (200). The vacuum cleaner body (100) can generate suction force through a suction motor (142) and provide suction force to the vacuum cleaner nozzle (300) through the extension tube (200). External dust can be introduced into the vacuum cleaner body (100) through the vacuum cleaner nozzle (300) and the extension tube (200).

[0110] The vacuum cleaner (1) may include a vacuum cleaner nozzle (300). The vacuum cleaner nozzle (300) may be connected to an extension tube (200). Accordingly, external air may be drawn into the vacuum cleaner body (100) of the vacuum cleaner (1) through the vacuum cleaner nozzle (300) and the extension tube (200) by the suction force generated in the vacuum cleaner body (100) of the vacuum cleaner (1).

[0111] For example, the vacuum cleaner nozzle (300) may be a suction nozzle. Here, the suction nozzle may refer to a device that touches the floor and directly sucks in dust and air. Accordingly, the suction force generated by the suction motor (142) mounted inside the vacuum cleaner body (100) of the vacuum cleaner is transmitted to the suction nozzle, and dust and air are sucked into the suction nozzle by this suction force.

[0112] The suction nozzle may be equipped with an agitator. The agitator rotates to scrape away dust from the floor or carpet, improving cleaning performance.

[0113] Meanwhile, the vacuum cleaner nozzle (300) includes a nozzle body and a suction port.

[0114] The nozzle body can be detachably connected to an extension tube (200) or the vacuum cleaner body (100). In addition, a path through which air and dust can flow can be formed within the nozzle body.

[0115] The suction port is formed on the bottom surface (the surface facing the ground) of the nozzle body, and may refer to a space through which external air and dust are introduced. The suction port is formed to communicate with the flow path formed on the nozzle body. Accordingly, when the suction motor (142) is operated, external air and dust can be introduced into the vacuum cleaner body (100) of the vacuum cleaner through the suction port by the suction force of the suction motor (142).

[0116]

[0117] Meanwhile, referring to Fig. 4, the flow of air in the vacuum cleaner (1) of the present invention is described as follows.

[0118] When the suction motor (142) is operated and air containing dust is sucked into the vacuum cleaner body (100), it passes through a passage (suction passage) inside the suction unit (120) and flows into the dust bin (170). Then, the air flowing into the dust bin (170) flows through a cyclone at least once in the dust separation unit (130), and dust in the air is gathered toward the lower side of the dust bin (170), and the air from which dust has been separated flows toward the suction motor (142).

[0119] At this time, the air flowing through the dust separation unit (130) to the suction motor (142) may contain relatively large foreign substances such as hair, and these can be filtered out in the filter unit (145). Meanwhile, relatively small foreign substances remaining in the air passing through the suction motor (142) can be filtered out in the HEPA filter (183). Through this, dust and foreign substances that have entered the vacuum cleaner body (100) can be prevented from being discharged out of the vacuum cleaner body (100) again.

[0120]

[0121] Meanwhile, conventional vacuum cleaners have a pre-filter positioned outside the motor housing, and the airflow path becomes longer as the air passes through the dust separation unit and then flows into the motor housing after passing through the pre-filter. In addition, conventional vacuum cleaners have a limitation in that the number of parts increases because a sealing structure is required for each component installed inside the main body of the vacuum cleaner. In particular, conventional vacuum cleaners have a limitation in that the surrounding components can be assembled even without the pre-filter installed, and the user cannot recognize that the pre-filter is not installed.

[0122] In order to comprehensively solve these problems, the vacuum cleaner (1) according to the embodiment of the present invention is provided with a filter unit (145) placed between the cyclone unit (131) and the suction motor (142), and is configured to prevent the vacuum cleaner (1) from being operated without the filter unit (145) installed by allowing the user to recognize when the filter unit (145) is not installed.

[0123] Below, the specific structure and separation process according to each embodiment will be described.

[0124]

[0125] Referring to FIGS. 3 to 5, the motor housing (150) includes a motor receiving portion (151) and a filter mounting portion (152), and the filter mounting portion (152) forms a space in which a filter portion (145) and a coupling portion (132) are arranged on the outside of the motor receiving portion (151).

[0126] The filter mounting portion (152) may be configured to include a connecting wall (152a) formed by protruding from the outer surface of the motor receiving portion (151), and an outer wall (152b) formed by protruding downward from the end of the connecting wall (152a) toward the inner surface of the main body housing (110).

[0127] The connecting wall (152a) can support a sealing member (144) to be described later, and can be positioned above the air intake port (146) of the motor receiving portion (151) and below the air outlet port (147) of the motor receiving portion (151).

[0128] The outer wall (152b) is formed to surround at least a portion of the motor receiving portion (151), and is arranged to face the outer surface of the motor receiving portion (151) and the coupling portion (132) and the filter portion (145). In addition, the outer wall (152b) may have an inner surface that supports the coupling portion (132) and the sealing member (144). Alternatively, the outer wall (152b) may have a fastening guide (153) that supports the coupling portion (132) and the sealing member (144) on the inner surface facing the coupling portion (132). The fastening guide (153) may be formed to protrude from the inner surface of the outer wall (152b), and may be provided in multiple numbers at equal intervals along the circumferential direction of the outer wall (152b). The fastening guide (153) is formed to have a support surface corresponding to the outer surface of the coupling portion (132).

[0129] In addition, a fastening structure is provided between the outer wall (152b) and the connecting portion (132). For example, the outer wall (152b) may have a fastening groove (154) into which the connecting portion (132) is fastened, and the connecting portion (132) may have a fastening projection (133) fastened to the fastening groove (154). Specifically, referring to FIG. 7, the outer wall (152b) has a fastening groove (154) formed in a fastening guide (153) that is open to one side in the circumferential direction. The fastening groove (154) is formed long along the circumferential direction and is open to one side so that the fastening projection (133) can be inserted into the fastening groove (154) through the open portion.

[0130] In addition, a stopper (155) may be provided in the fastening groove (154) to fix the inserted fastening projection (133). The stopper (155) is formed in the form of a protrusion on the inner surface of the outer wall (152b), is formed on the inner side of the fastening groove (154), and is fixed by being caught in the catch groove (133b) formed in the fastening projection (133), thereby fixing the fastening projection (133) to the fastening groove (154).

[0131] The dust separation unit (130) includes a coupling unit (132) arranged on the inner side of the filter mounting unit (152). The coupling unit (132) is arranged between the outer wall (152b) and the filter unit (145). This coupling unit (132) is supported by a coupling guide (153) and is fastened to the motor housing (150). Specifically, the coupling unit (132) is fastened to the outer wall (152b) by forming a fastening protrusion (133) on the outer circumferential surface.

[0132] Referring to Fig. 6, the fastening projection (133) is formed to protrude from the outer surface of the coupling portion (132) and may be formed along the circumferential direction of the coupling portion (132). The fastening projection (133) may be provided with a guide structure at the end in the circumferential direction so as not to be caught by the stopper (155) when inserted into the fastening groove (154). Specifically, the coupling portion (132) may be formed with a guide portion (133a) formed at one end in the circumferential direction of the fastening projection (133) so that the protrusion amount becomes smaller as it goes toward the end. The guide portion (133a) may be, for example, an inclined surface connected to the outer surface of the coupling portion (132).

[0133] In addition, the connecting portion (132) may be provided with a structure to provide a sense of engagement when the connecting projection (133) is inserted into the connecting groove (154) and rotated at a certain angle. Specifically, the connecting portion (132) may be formed with a hooking groove (133b), and a stopper (155) that is hooked and fastened to the hooking groove (133b) may be formed on the outer wall (152b). The hooking groove (133b) is formed at a position spaced from the other end in the circumferential direction of the connecting projection (133), and when the stopper (155) is hooked and fastened, it can provide a sense of operation to the user.

[0134] Additionally, the coupling portion (132) may be provided with a fixing projection (134) at a position spaced apart from the other end in the circumferential direction of the fixing projection (133). The fixing projection (134) is formed to have a size larger than the spacing of the fixing groove (154) and may be supported by the fixing guide (153) when the dust separation portion (130) rotates, thereby limiting the dust separation portion (130) to rotate only at a certain angle.

[0135] Fig. 8a shows a state in which the dust separation unit (130) moves axially, the coupling unit (132) is supported by the sealing member (144), and the fastening projection (133) is positioned at a height corresponding to the fastening groove (154). In this state, when the dust separation unit (130) rotates, as shown in Fig. 8b, the fastening projection (133) passes the stopper (155) by the guide unit (133a), and the fastening projection (133) is inserted into the fastening groove (154), and the stopper (155) is caught and fastened in the catch groove (133b), so that the dust separation unit (130) is fastened to the filter mounting portion (152).

[0136] Meanwhile, the filter unit (145) is disposed inside the filter mounting portion (152) and is disposed on the inner side of the coupling portion (132). The filter unit (145) is disposed between the coupling portion (132) and the filter mounting portion (152), is fixed to the motor housing (150), and is disposed spaced apart from the coupling portion (132). According to this structure, when the dust separation portion (130) rotates to be fastened to the filter mounting portion (152), the filter unit (145) is prevented from rotating together with the dust separation portion (130). In addition, when the dust separation portion (130) is fastened to the filter mounting portion (152), the resistance due to friction with the surrounding structures is minimized, making it easy to install and detach the dust separation portion (130).

[0137] This filter unit (145) may be composed of a filter net (145c) and may be composed of a mesh net (145c) that is formed to be open toward the top so as to surround at least a portion of the motor housing (150). This filter unit (145) may be a pre-filter and prevents relatively large foreign substances from entering the inside of the motor housing (150).

[0138] The filter unit (145) is arranged above the cyclone unit (131) and below the suction motor (142). The exhaust port (131a) of the cyclone unit (131) and the air intake port (146) of the motor receiving unit (151) are arranged to face each other with the filter unit (145) in between. According to this structure, the air flowing upward through the cyclone unit (131) continues to flow upward and passes through the fan driving unit (140). Therefore, the shortest flow path for the air can be provided, so that the suction power of the cleaner (1) can be improved.

[0139] In addition, the filter unit (145) may further include a lower frame (145b) and an upper frame (145a). The lower frame (145b) is arranged below the filter net (145c) to form a shape below the filter net (145c), and further includes a lower filter net on the inside. This lower frame (145b) may be formed into a polygonal shape in which a mountain portion (145ba) protruding outward in the radial direction and a curved portion (145bb) protruding inward in the radial direction are alternately arranged along the circumferential direction.

[0140] Specifically, referring to Fig. 8, the filter section (145) may be formed in a pentagonal star shape with the lower portion facing the cyclone section (131). The mountain section (145ba) may be provided with a border formed along the circumferential direction in the protruding portion, and the curved section (145bb) may be formed in a convex protruding portion.

[0141] In particular, referring to FIG. 9, the cyclone unit (131) has outlets (131a) arranged along two circles with different diameters. Five outlets (131a) can be arranged at equal intervals along a small circle, and ten outlets (131a) can be arranged at equal intervals along a large circle. Accordingly, the lower frame (145b) of the filter unit (145) is provided in a shape in which five mountain sections (145ba) and five curved sections (145bb) are arranged alternately. In this way, when the number of outlets (131a) arranged along the small circle is n, the filter unit (145) can have the lower frame (145b) formed in an n-angle shape. According to this structure, the air passing through the outlets (131a) can evenly pass through the filter unit (145), and the even flow has the effect of improving the flow efficiency.

[0142] Meanwhile, the upper frame (145a) is disposed on the upper portion of the filter net (145c) and may be formed hollow inside and fixed to the motor housing (150). The upper frame (145a) may be disposed with a motor receiving portion (151) inserted therein. In addition, the inner surface of the upper frame (145a) may support the motor receiving portion (151). The upper frame (145a) may be fixed to the motor housing (150) by fastening the motor housing (150) and the dust separation portion (130). In addition, a sealing member (144) may be provided on the upper frame (145a).

[0143] The sealing member (144) may be provided integrally with the filter part (145) through injection molding or the like, or may be attached to the filter part (145) through an adhesive or the like. In addition, the sealing member (144) may be provided to the filter part (145) through a bonding structure.

[0144] This sealing member (144) may be formed in a hollow ring shape and may be integrally provided at the upper end of the filter unit (145), and may be composed of a body (144a), a first support unit (144b), and a second support unit (144c). The body (144a) may be integrally provided at the upper end of the filter unit (145), and may include a first support unit (144b) that supports the filter mounting unit (152), and a second support unit (144c) that supports the dust separation unit (130).

[0145] For example, the body (144a) may be formed in a hollow ring shape. The first support portion (144b) may be provided at one end of the body (144a). The first support portion (144b) may be formed to protrude from one end of the body (144a) toward the filter mounting portion (152), and may be formed to protrude toward the other end of the body (144a). That is, the first support portion (144b) may be formed such that the inner end of the body (144a) protrudes upward, and further protrudes outward in the radial direction, such that the protruding end faces the outer end of the body (144a). In addition, the protruding end of the first support portion (144b) may elastically support the connecting wall (152a) of the filter mounting portion (152).

[0146] The second support member (144c) may be provided on the other end of the body. The second support member (144c) may be formed by protruding the outer end of the body (144a) downward, and the protruding end may support the upper end of the coupling member (132). In addition, the outer circumferential surface of the second support member (144c) may be supported by a fastening guide (153). Here, the fastening guide (153) guides the sealing member (144) and the coupling member (132) so that they can be aligned in the correct position, and the outer surface of the sealing member (144) and the outer surface of the coupling member (132) may be supported so that an imaginary line connecting the center of the dust separation member (130) and an imaginary line connecting the center of the filter member (145) are aligned. This fastening guide (153) is provided with a tapered portion formed so that the thickness from the outer wall (152b) gradually becomes thinner as it goes toward the lower end, so that the filter portion (145) and the dust separation portion (130) can be guided toward the inside of the fastening guide (153).

[0147] In addition, the upper frame (145a) may further be provided with a sealing member support (145d). The sealing member support (145d) may be provided by being coupled to the upper end of the upper frame (145a), and the sealing member (144) may be provided integrally with the upper end. In addition, the sealing member support (145d) may be provided with a contact prevention portion (145da) formed by protruding a portion of the outer circumference along the circumference, and a second support portion (144c) may be arranged on the outer side of the contact prevention portion (145da). In addition, the sealing member support (145d) may be provided with a support wall (145db) formed by protruding a portion of the upper surface to support the inner side of the first support portion (144b).

[0148] This sealing member (144) is integrally provided in the filter section (145) and elastically supports the motor housing (150) and the dust separation section (130), respectively, thereby sealing the outer space (100a) of the dust separation section, the space (100b) between the dust separation section and the filter section, and the inner space (100c) of the filter section.

[0149] Specifically, the sealing member (144) can seal between the outer space (100a) of the dust separation unit and the inner space (100b) of the dust separation unit, while sealing between the outer space (100b) of the filter unit and the inner space (100c) of the filter unit.

[0150] In addition, the sealing member (144) seals between the upper portion of the filter portion (145) and the connecting wall (152a) while sealing between the joint portion (132) and the connecting wall (152a). Specifically, the sealing member (144) can elastically support each of the joint portion (132) and the connecting wall (152a) in the vertical direction, while elastically supporting each of the upper portion of the filter portion (145) and the connecting wall (152a) in the vertical direction.

[0151] With this configuration, the air on the outer space (100a) of the dust separation unit that is introduced through the suction unit (120) passes through the mesh of the cyclone unit (131) and the dust is separated by the cyclone flow, and the air on the space (100b) between the dust separation unit and the filter unit that is discharged through the discharge port (131a) of the cyclone unit (131) passes through the filter unit (145). In addition, the sealing member (144) seals multiple spaces with one configuration, thereby reducing the number of parts of the vacuum cleaner (1).

[0152]

[0153] Below, the installation structure of the filter unit (145) is described. The filter unit (145) can be installed in the motor housing (150) by fastening the motor housing (150) and the dust separation unit (130).

[0154] When the dust separation unit (130) is fastened to the motor housing (150), it moves in the axial direction, and when the end of the coupling unit (132) is supported by the sealing member (144), it can rotate in the supported state and be fastened to the filter mounting unit (152).

[0155] And, when the dust separation unit (130) is fastened to the filter mounting portion (152), the dust separation unit (130) is arranged so that the upper end of the coupling portion (132) is spaced apart from the connecting wall (152a). In addition, the dust separation unit (130) and the filter mounting portion (152) are arranged so as to be spaced apart from each other along the longitudinal direction of the main body housing (110). In addition, the dust separation unit (130) and the filter mounting portion (152) are arranged so as to be spaced apart from each other along the motor axis of the suction motor (142). In addition, the dust separation unit (130) and the filter mounting portion (152) are arranged so as to be spaced apart from each other in the vertical direction. That is, the distance from the upper end of the hooking portion (132) to the fastening groove (154) in the connecting wall (152a) is provided longer than the distance from the fastening projection (133). In addition, the filter portion (145) is arranged so as to be spaced apart from the connecting wall (152a) in the vertical direction. And, a sealing member (144) is inserted into the spaced apart space to support between the filter mounting portion (152) and the dust separation portion (130), and to support between the filter mounting portion (152) and the filter portion (145).

[0156] If the dust separation unit (130) is fastened to the motor housing (150) without the filter unit (145) being inserted, there is a problem in that it is difficult to position the fastening projection (133) at the position of the fastening groove (154), making fastening difficult. That is, the dust separation unit (130) must rotate with the fastening projection (133) positioned close to the opening of the fastening groove (154) so ​​that the fastening projection (133) is inserted into the fastening groove (154). However, since there is no configuration in which the upper part of the coupling portion (132) can be seated, it is not easy for the user to fasten, and the user can easily recognize whether the filter unit (145) is not mounted.

[0157] In addition, even if the dust separation unit (130) is fastened to the motor housing (150) while the filter unit (145) is not mounted, the user can easily recognize whether the filter unit (145) is not mounted as the dust separation unit (130) makes a rattling movement in the up and down direction.

[0158] When the filter part (145) is mounted and the sealing member (144) is inserted between the connecting part (132) and the connecting wall (152a), and the fastening projection (133) is fastened to the fastening groove (154), the connecting part (132) is supported by the sealing member (144) and elastically supported in the up-down direction, and the dust separation part (130) can be stably fastened.

[0159] According to this structure, as the dust separation unit (130) rotates in one direction and the fastening projection (133) is separated from the fastening groove (154), the dust separation unit (130) and the filter unit (145) are released from the motor housing (150). Then, the dust separation unit (130) can be separated through the lower opening of the dust bin main body (171), and the filter unit (145) can also be separated. Alternatively, the dust bin main body (171) can be separated first from the main body housing (110), and then the dust separation unit (130) and the filter unit (145) can be separated.

[0160] Conversely, the dust separation unit (130) can be inserted into the inside of the fastening guide (153) with the filter unit (145) placed inside the coupling unit (132), and when the coupling unit (132) and the sealing member (144) are supported by the connecting wall (152a), the dust separation unit (130) is rotated in the other direction to fasten the fastening protrusion (133) to the fastening groove (154). At this time, the inner surface of the dust separation unit (130) is arranged to be spaced apart from the filter unit (145) so that only the dust separation unit (130) rotates in the other direction. The filter unit (145) is provided with a contact prevention unit (145da) so that the outer surface is arranged to be spaced apart from the dust separation unit (130) in the radial direction.

[0161]

[0162] Although the present invention has been described in detail through specific examples, this is for the purpose of specifically explaining the present invention, and the present invention is not limited thereto, and it is clear that the present invention can be modified or improved by a person having ordinary knowledge in the relevant field within the technical spirit of the present invention.

[0163] All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be made clear by the appended claims.
