Description

vacuum cleaner

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

[0002] A vacuum cleaner is a device that cleans the indoors by sucking up foreign substances such as dust.

[0003] Vacuum cleaners can be classified into manual vacuum cleaners, which are used for cleaning by moving the cleaner directly, and automatic vacuum cleaners, which are used for cleaning by driving on their own. Manual vacuum cleaners can be classified into canister-type vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick-type vacuum cleaners depending on the form of the cleaner.

[0004] In the past, canister-type vacuum cleaners were widely used for household use, but recently, handheld and stick vacuum cleaners, which offer improved convenience by providing the dust bin and the main body as a single unit, are becoming more popular.

[0005] Conventional vacuum cleaners generally include a housing equipped with a suction section and an exhaust section, a fan that moves air entering the suction section to the exhaust section, a separator that separates foreign matter from the air moved by the fan, a battery that supplies power to the fan, and a handle provided in the housing.

[0006] In conventional vacuum cleaners, when air containing foreign substances enters the housing through the intake port, the foreign substances are separated by a filter. In particular, the filter is equipped with a primary filter and a secondary filter.

[0007] The first filter preferentially separated large particles from the foreign substances contained in the air entering the intake. The second filter separated small particles from the air that passed through the first filter.

[0008] Conventional vacuum cleaners had a problem where foreign matter falling from the secondary filter accumulated at the bottom of the secondary filter.

[0009] In addition, conventional vacuum cleaners had a problem where foreign matter accumulated at the bottom of the secondary filter, and when the vacuum cleaner was restarted, the foreign matter accumulated at the bottom of the secondary filter would scatter.

[0010] In addition, conventional vacuum cleaners had the problem of having to directly remove the secondary filter from the housing and clean the inside of the housing to remove foreign matter accumulated at the bottom of the secondary filter.

[0011] In addition, conventional vacuum cleaners had the problem of having to manually pull out and remove the secondary filter to remove small foreign particles attached to the secondary filter.

[0012] The present invention aims to solve the problem of efficiently removing foreign substances separated from a first filter by including a discharge channel that guides foreign substances separated from a first filter to a collection space.

[0013] The present invention aims to solve the problem of enabling easy replacement of a filter unit by including a pull-out body equipped with a handle.

[0014] The present invention aims to solve the problem of effectively removing foreign substances attached to a first filter without withdrawing the filter unit from the housing by including a rotating plate provided to rotate the foreign substance removal unit.

[0015] The present invention aims to solve the problem of improving the performance of a vacuum cleaner by including a plurality of sealing parts to prevent air leakage inside the vacuum cleaner.

[0026] The above filtration unit may further include a withdrawal body coupled to the upper part of the first filter, and may further include a second sealing unit that prevents air from moving between the withdrawal body and the first body.

[0027] The above vacuum cleaner may further include: a housing outlet provided to penetrate the bottom surface of the housing and communicating with the first chamber and the second chamber; a cover provided to be detachably attached to the housing to open and close the housing outlet; and a third sealing part that prevents air from moving between the cover and the bottom surface of the second body.

[0028] The above vacuum cleaner may further include a rotating plate coupled to the cover and having at least a portion rotatably provided so as to rotate the foreign matter removal part.

[0047] FIGS. 1 and FIGS. 2 illustrate an example of the vacuum cleaner of the present invention.

[0048] The vacuum cleaner of the present invention comprises a housing (1) having a hollow cylinder shape, an intake unit (11) and an exhaust unit (153) provided in the housing (1), a fan (5) provided inside the housing (1) for moving air from the intake unit (11) to the exhaust unit (153), a chamber (4) that guides the air introduced into the intake unit (11) to the fan (5) and separates foreign matter from the air using centrifugal force, and a handle (7) provided in the housing (1) so that a user can hold it with their hand.

[0049] The intake portion (11) is provided on the circumferential surface of the housing and can guide air from outside the housing into the housing.

[0050] The exhaust section (153) is provided to penetrate the housing and can guide the air inside the housing to the outside of the housing.

[0051] The handle (7) may be provided to be located at a point (180 degrees apart) symmetrical to the point where the suction part (11) is located within the space provided by the circumferential surface of the housing (1).

[0052] As illustrated in FIG. 2, a partition wall (19) is provided inside the housing (1) to divide the internal space of the housing into an upper space (1a) and a lower space (1b). The partition wall (19) is provided with a partition wall penetration hole (191) that connects the upper space (1a) and the lower space (1b). The partition wall penetration hole (191) is provided to penetrate the partition wall.

[0053] The intake section (11) is provided on the circumferential surface of the housing (1) to introduce outside air into the lower space (1b). The intake section (11) may include an intake port (113) provided to penetrate the circumferential surface of the housing (1), and an intake pipe (111) extending from the intake port (113) toward a direction away from the center of the housing (1) (a direction away from the handle, Y-axis direction).

[0054] Although not illustrated in the drawing, the vacuum cleaner of the present invention may further include an extension tube detachably provided on the suction tube (111), and a nozzle provided at the free end of the extension tube to move foreign matter to the extension tube.

[0055] The exhaust part (153) is provided to penetrate the upper surface or circumferential surface of the housing (1) to discharge air inside the housing (1) to the outside, and FIG. 2 illustrates an example in which the exhaust part (153) is provided on the upper surface of the housing (11).

[0056] The upper surface of the housing (1) is provided with a housing through hole (14, see FIG. 1), and the housing through hole (14) may be provided to be opened and closed by an upper cover (15).

[0057] Additionally, a filter unit (43) for filtering air may be provided inside the housing, and the filter unit (43) may be provided so that a user can detach it from the housing (1) and wash it. However, a foreign matter removal unit (44) may be provided on the inside of the filter unit (43) to remove foreign matter attached to the filter unit. A detailed description is provided below.

[0058] The upper cover (15) may be provided as an upper cover body (151) having a shape corresponding to the shape of the housing through hole (14), in which case the exhaust part (153) may be provided as a plurality of holes penetrating the upper cover body.

[0059] When the exhaust part (153) is provided on the circumferential surface of the housing (1), the air discharged from the exhaust part (153) can be directed toward the handle (7).

[0060] Accordingly, it is preferable that the exhaust part (153) be provided in an area located opposite to the direction in which the handle (7) is located within the space provided by the circumferential surface of the housing (1).

[0061] On the bottom surface of the housing (1) (one side of the first housing located opposite the exhaust port), a housing discharge port (17) is further provided for discharging foreign matter stored inside the housing (1) to the outside, and the housing discharge port (17) is opened and closed by a cover (18).

[0062] The above cover (18) may be provided as a cover body (181) rotatably fixed to the housing (1). In this case, the circumferential surface of the housing (1) may be provided with an axis (12) forming the rotational center of the cover body (181) and a fastening part (13) provided at a position facing the axis (12). The cover body (181) may be provided with a first cover fastening part (183) coupled to the axis (12) and a second cover fastening part (185) provided at the free end of the cover body (181) and detachably coupled to the fastening part (13).

[0063] The fan (5) is provided in the upper space (1a) of the housing and moves air supplied from the bulkhead penetration hole (191) to the exhaust section (153), and the chamber (4) is provided in the lower space (1b) of the housing and provides a flow path that guides air introduced into the intake section (11) to the fan (5). Foreign substances such as dust contained in the air can be separated from the air by centrifugal force while moving to the fan (5) along the flow path provided by the chamber (4). The specific structure is described below.

[0064] The above chamber (4) includes a chamber forming part (42) that divides the lower space (1b) of the housing into a first chamber (41a) and a second chamber (41b), a filtering part (43) that filters foreign substances contained in the air, and a foreign substance removal part (44) that is rotatably provided on the filtering part (43) to remove foreign substances attached to the filtering part (43).

[0065] Specifically, the chamber forming part (42) is provided inside the housing and is configured to distinguish between a first chamber (41a) communicating with the intake part (11) and a second chamber (41b) that guides the air introduced into the first chamber (41a) to the exhaust part (153).

[0066] The chamber forming part (42) is provided with a cylinder that is fixed to the partition wall (19) at one end and contacts the cover (18) at the other end, so that the lower space (1b) can be divided into two chambers (41a, 41b).

[0067] The first chamber (41a) can communicate the lower space with the intake section (11), and the second chamber (41b) can guide the air introduced from the first chamber (41a) to the partition penetration hole (191).

[0068] The second chamber (41b) may be provided with a first body (421) fixed to the partition wall (19) and a second body (423) fixed to the first body (421). In this case, the partition wall penetration hole (191) may be provided to connect the second chamber (41b) with the upper space (1a) of the housing. That is, the first body (421) may be provided in a shape that surrounds the partition wall penetration hole (191).

[0069] The first body (421) and the second body (423) must be provided in the shape of a cylinder with a hollow interior, and the second body (423) may be provided such that one end is fixed to the free end of the first body (421) and the other end contacts the cover (18).

[0070] The circumferential surface of the first body (421) may be provided with the chamber forming part (42) for primarily separating foreign substances from the air introduced from the intake part (11).

[0071] Accordingly, air introduced into the first chamber (41a) through the intake section (11) can pass through the chamber forming section (42) and be supplied to the filter section (43).

[0072] The above filtration unit (43) may be equipped with a fixed body (432) that is fixed inside the chamber forming unit (42) and divides the interior of the chamber forming unit (42) into a filtration space (411) and a collection space (412), and a first filter (431) that is fixed to the fixed body (432) and filters air.

[0073] The above filtration space (411) is a space connected to the above partition penetration hole (191), and the above collection space (412) may be a space not connected to the above partition penetration hole (191).

[0074] The above foreign substance removal unit (44) may be provided with a rotating body (441) that is rotatably provided on the fixed body (432) and penetrates the first filter (431), a connecting passage (442) provided inside the rotating body (441) and communicating with the exhaust unit (153), a rotating body penetration hole (443) that penetrates the rotating body (441) and guides air passing through the first filter (431) to the connecting passage (442), and a projection (444) provided on the circumferential surface of the rotating body (441) to separate foreign substances from the first filter (431). Detailed information is explained in FIG. 5.

[0075] As illustrated in FIG. 2, the fan (5) may include a case (51) provided in the upper space (1b) of the housing, an impeller (57) rotatably provided inside the case, and a motor (54) fixed to the case to rotate the impeller (57).

[0076] The above case (51) is provided with a case intake port (511) and a case exhaust port (513). It is preferable that the case intake port (511) be provided on one side of the case (51) facing the bulkhead penetration hole (191), and that the case exhaust port (513) be provided to penetrate one side of the case (51) facing the exhaust section (153). This is to minimize flow resistance between the bulkhead penetration hole (191) and the exhaust section (153).

[0077] The motor (54) is fixed to a motor support (515) provided in a case (51). FIG. 2 illustrates an example in which the motor support (515) is positioned between the case intake port (511) and the case exhaust port (513), and the rotating shaft (545) passes through the motor support (515) and is connected to an impeller (57). That is, the motor (54) may include a fixed part (541) fixed to the motor support (515), a stator (543) provided inside the fixed part, and a permanent magnet (546) fixed to the free end of the rotating shaft (545) (one end of the rotating shaft located inside the fixed part).

[0078] The motor (54) may be provided to receive power through a power source provided indoors, or it may be provided to receive power through a battery (6) that is detachable from the housing (1). In the latter case, the housing (1) must be provided with a battery housing (61) that provides a space for accommodating the battery (6).

[0079] The battery housing (61) may be provided to protrude in a direction away from the intake portion (11) from the rear surface of the housing (1) (a surface located opposite to the direction in which the intake portion is located). In this case, the handle (7) may be provided with a handle body (71) fixed to the battery housing (61) and a connecting body (73) connecting the handle body to the circumferential surface of the housing (1).

[0080] The operation process of a vacuum cleaner having the structure described above is explained below.

[0081] When power is supplied to the motor (54) and the impeller (57) rotates, air is introduced into the first chamber (41a) through the intake pipe (111) and the intake port (113). The intake pipe (111) is equipped with a guide (115) that causes the air discharged from the intake port (113) to flow tangentially to the circumferential surface of the first chamber (41a). Accordingly, the air introduced into the first chamber (41a) will undergo cyclone flow along the circumferential surface of the first chamber (41a).

[0082] When air flows in a cyclone inside the first chamber (41a), foreign matter moves to the circumferential surface of the first chamber (41a) by centrifugal force and then moves to the cover (18) provided on the bottom surface of the housing by gravity, and the air will flow into the second chamber (41b).

[0083] The air introduced into the second chamber (41b) can have large foreign particles separated by the second filter (422) provided in the chamber forming part (42). The foreign substances separated by the second filter (422) can move to the housing outlet (17).

[0084] The air passing through the chamber forming part (42) can pass through the filtration part (43). The filtration part (43) can separate small foreign substances by the first filter (431). That is, the first filter (431) can separate finer foreign substances than the second filter (422).

[0085] The foreign substance separated by the first filter (431) may be moved to the collection space (412) or attached to the first filter (431).

[0086] Foreign substances attached to the first filter (431) can be moved to the collection space (412) by the foreign substance removal unit (44) described later.

[0087] Accordingly, the user can remove foreign matter accumulated in the collection space (412) and the lower part of the first chamber (41a) by opening the housing outlet (17) through the cover (18).

[0088] FIG. 3 illustrates an example of a chamber forming part provided in the present invention.

[0089] The chamber forming part (42) may include a second filter (422) that filters the air flowing into the second chamber (41b).

[0090] However, the chamber (4) may include at least one of the first filter (431) and the second filter (422). That is, the first filter (431) may be provided in the filtration section (43), but the second filter (422) may not be provided in the chamber forming section (42).

[0091] However, in order to reduce the amount of fine dust emitted into the indoor space, it is preferable that the chamber (4) be equipped with both the first filter (431) and the second filter (422).

[0092] The second filter (422) may be configured to filter foreign substances of the same size as the first filter (41b), or may be configured to filter foreign substances of different sizes. However, in order to minimize the amount of fine dust emitted into the indoor space, it is preferable that the first filter (41a) filters foreign substances smaller in size than those filtered by the second filter (41b).

[0093] Specifically, the second filter (422) may be provided as a mesh structure filter. The second filter (422) may be a thin mesh made of plastic or metal, etc. Additionally, the second filter (422) may serve to primarily remove foreign substances such as hair particles.

[0094] As illustrated in FIG. 3(b), the second filter (422) may be provided in multiple numbers along the circumferential surface of the chamber forming part (42). That is, the second filter (422) can primarily remove foreign substances from the air flowing from the first chamber (41a) to the second chamber (41b).

[0095] The chamber forming part (42) may include a first body (421) and a second body (423).

[0096] The first body (421) is configured to communicate with the first chamber (41a) and the second chamber (41b), thereby providing a space to guide air introduced from the first chamber (41a) to the exhaust section (153).

[0097] The second body (423) is provided at the bottom of the first body (421) and can provide a space capable of collecting foreign matter that has moved along the discharge path (432b) described later. That is, the second body (423) may include the collection space (412).

[0098] The cover (18) may be attached to the lower part of the second body (423), and the user can open the cover (18) to effectively remove foreign substances collected in the collection space (412).

[0099] Additionally, the first body (421) and the second body (423) may be provided as a single unit. That is, the first body (421) and the second body (423) may be designed and manufactured as a single unit. Accordingly, the chamber forming part (42) has the advantage of reducing manufacturing costs by decreasing the number of parts, and making assembly and maintenance easier by enabling injection molding. However, it is not necessary for them to be provided as a single unit, and the vacuum cleaner (100) may be determined by considering the space efficiency inside the chamber (4).

[0100] The diameter of the chamber forming part (42) may be wider than the diameter of the filter part (43). This is because the chamber forming part (42) must be able to accommodate the filter part (43) in order to guide the air introduced into the second chamber (41b) or to further separate foreign substances.

[0101] Additionally, the second body (423) may be provided in a cylindrical shape rather than a cone shape. FIG. 3 illustrates a second body (423) in a cone shape. That is, the second body (423) may be provided in either a cone shape or a cylindrical shape.

[0102] If the second body (423) is provided in a cylindrical shape, the collection space (412) can be expanded. Accordingly, the vacuum cleaner (100) can reduce the space for collecting foreign substances separated from the second filter (422) and expand the space for collecting foreign substances separated from the first filter (431).

[0103] However, since the second filter (422) separates foreign substances of larger particles compared to the first filter (431), it is not desirable to reduce the space available to collect foreign substances separated by the second filter (422). Therefore, it is preferable that the second body (423) be provided in a cone shape as shown in FIG. 3.

[0104] FIG. 4 illustrates an example of a filtration unit provided in the present invention, and FIG. 5 illustrates an example of a foreign substance removal unit provided in the present invention.

[0105] The above filtering unit (43) may include the first filter (431), the fixed body (432), and the withdrawal body (433).

[0106] As illustrated in FIG. 2, the fixed body (432) is fixed inside the chamber forming part (42) so that the inside of the chamber forming part (42) can be divided into a filtration space (411) and a collection space (412). That is, the first filter (431) and the withdrawal body (433) can be provided in the filtration space (411).

[0107] The fixed body (432) may include a discharge channel (432b) that guides foreign substances separated from the first filter (431) to the collection space (412), and a fixed part (432a) that is coupled to the chamber forming part (42) to prevent rotation of the filter part (43).

[0108] The above discharge channel (432b) may be provided between the first filter (431) and the second filter (422).

[0109] The discharge channel (432b) can guide foreign substances separated from the first filter (431) to the collection space (412) provided in the second body (423). Accordingly, the discharge channel (432b) is provided below the first filter (431), but can be provided between the first filter (431) and the second filter (422).

[0110] As shown in FIG. 4, the discharge channels (432b) may be provided in multiple numbers and spaced apart at regular intervals.

[0111] Air introduced into the second chamber (41b) may flow along the circumferential surface of the chamber forming part (42). Additionally, foreign substances may be separated from the air passing through the chamber forming part (42) by the first filter (431). Accordingly, the discharge passage (432b) may be provided in multiple numbers to remove foreign substances from the air flowing along the circumferential surface of the chamber forming part (42).

[0112] The fixed body (432) may include a filter groove (not shown) that provides a space for the first filter (431) to be coupled to the upper part, and a fixed body through hole (not shown) that provides a space for the foreign matter removal part (44) to be provided therein.

[0113] The above fixed body through-hole may be formed as a through hole in the central part of the fixed body (432). The foreign substance removal part (44) may be rotatably fixed to the fixed body (432). Accordingly, at least a portion of the foreign substance removal part (44) may be included inside the fixed body through-hole.

[0114] The filter grooves may be provided in multiple numbers along the circumferential surface of the fixed body (432) on the outer surface of the fixed body through hole. That is, the filter grooves may be provided in a groove shape in which the first filter (431) can be fixed.

[0115] The fixing part (432a) provided in the fixed body (432) can be fixed to the chamber forming part (42) so that only the foreign matter removal part (44) can rotate.

[0116] As illustrated in FIGS. 3 and 4, the fixing part (432a) can be fixed to the anti-rotation part (425) provided in the chamber forming part (42). For example, the fixing part (432a) may be provided in a groove shape and the anti-rotation part (425) may be provided in a protruding shape so that they can be fixed to each other.

[0117] The fixed part (432a) can be detachably fixed to the rotation prevention part (425). The filter part (43) can be discharged to the outside through the withdrawal body (433) for cleaning or replacement. Therefore, it is preferable that the fixed part (432a) be fixed so as to be detachable from the rotation prevention part (425).

[0118] Additionally, the fixing part (432a) may be provided in multiple numbers to improve fixing force. It is preferable that the fixing part (432a) be provided in the same number as the rotation prevention part (425). The fixing part (432a) may be provided in various forms as long as it can be detachably fixed to the rotation prevention part (425).

[0119] As illustrated in FIGS. 4 and 5, the withdrawal body (433) may be coupled to the upper part of the first filter (431). Additionally, the withdrawal body (433) may include a withdrawal body through hole (433a) that guides air passing through the rotating body through hole (443) to the exhaust part (153), and a handle (433b) provided to enable the filter part (43) to be withdrawn to the outside of the housing (1).

[0120] The above-mentioned extraction body through-hole (433a) can guide air passing through the filter section (43) to the bulkhead through-hole (191). Specifically, air passing through the rotating body through-hole (443) can be guided to the bulkhead through-hole (191) through the connecting passage (442) to be described later.

[0121] The above-mentioned withdrawal body through hole (433a) can accommodate at least a portion of the above-mentioned foreign matter removal part (44).

[0122] The handle (433b) may be provided on the upper part of the pull-out body (433) to enable the filter unit (43) to be pulled out. The user can conveniently pull out the filter unit (43) using the handle (433b). Therefore, there is an advantage that the user can smoothly clean and replace the filter unit (43).

[0123] Additionally, the withdrawal body (433) may include a filter groove (not shown) for detachably securing the first filter (431). The withdrawal body (433) may include the filter groove at its lower portion to secure the first filter (431). Additionally, to replace the first filter (431), the withdrawal body (433) may be configured to allow the first filter (431) to be separated from the filter groove.

[0124] That is, it is preferable that at least one of the fixed body (432) and the withdrawal body (433) be detachably fixed to the first filter (431).

[0125] As illustrated in FIG. 5, the foreign substance removal unit (44) may include a rotating body (441) that is rotatably provided on the fixed body (432) and penetrates the first filter (431), a connecting passage (442) provided inside the rotating body and communicating with the exhaust unit (153), a rotating body penetration hole (443) that penetrates the rotating body (441) and guides air that has passed through the first filter (431) to the connecting passage (442), a projection (444) provided on the circumferential surface of the rotating body to separate foreign substances from the first filter (431), and a support unit (445) that supports the fixed body (432).

[0126] The above-mentioned rotating body through hole (443) can guide air that has passed through the first filter (431) to the connecting passage (442). Accordingly, the above-mentioned rotating body through hole (443) can be provided along the circumferential surface of the above-mentioned rotating body (441).

[0127] Additionally, the rotating body through-holes (443) may be formed in multiple numbers so that air passing through the first filter (431) is efficiently discharged to the exhaust section (153). The rotating body through-holes (443) may be provided in an upward and downward direction to correspond to the height of the first filter (431).

[0128] The above connecting passage (442) can guide air introduced through the rotating body penetration hole (443) to the bulkhead penetration hole (191). That is, the connecting passage (442) can be provided in the innermost part of the second chamber (41b) so that air with the lowest foreign matter content is discharged to the exhaust section (153).

[0129] The support member (445) can support the fixed body (432). The support member (445) can support the filter member (43) so that the filter member (43) can be provided in the filter space (411).

[0130] Specifically, the support member (445) may be provided as a protrusion so that the fixed body (432) can be seated thereon. The support member (445) is provided to protrude along the circumferential surface of the rotating body (441) so that the fixed body (432) can be seated on the upper part of the protrusion. Accordingly, the foreign substance removal member (44) may be provided inside the filter member (43), and the foreign substance removal member (44) may be provided to be rotatable while the filter member (43) is fixed.

[0131] The operation method of the above foreign substance removal unit (44) is described below.

[0132] As described above, the filter portion (43) can be fixed to the chamber forming portion (42) through the fixing portion (432a). Additionally, the filter portion (43) can be seated on the upper part of the support portion (44). That is, the filter portion (43) can be fixed to the chamber forming portion (42) so as not to rotate.

[0133] The above foreign matter removal unit (44) may be configured so that the rotating body (441) rotates by means of a rotating plate (9) to be described later.

[0134] When the rotating body (441) is rotated by the rotating plate (9), the protrusion (444) can physically contact the first filter (431) to separate foreign substances.

[0135] Specifically, the protrusion (444) may be provided to contact the inner side of the first filter (431). When the rotating body (441) is rotated by the rotating plate (9), the protrusion (444) can separate foreign substances attached to the inner side of the first filter (431) while rotating. Consequently, since the protrusion (444) can apply physical force to the inner side of the first filter (431), foreign substances attached to the outer side of the first filter (431) can also be separated.

[0136] That is, the air introduced into the second chamber (41b) attaches foreign substances to the first filter (431), and the foreign substance removal unit (44) is rotatably provided so as to effectively separate the foreign substances attached to the first filter (431).

[0137] Therefore, the above vacuum cleaner (100) has the advantage of preventing performance degradation due to clogging of the first filter (431) and significantly extending the lifespan of the first filter (431).

[0138] As mentioned above, foreign substances separated from the first filter (431) can be collected into the collection space (412) through the discharge channel (432b) and discharged to the outside.

[0139] FIG. 6 illustrates an example of a second chamber provided in the present invention, and FIG. 7 illustrates an example of a vacuum cleaner having a rotating plate on the cover.

[0140] The interior of the second chamber (41b) may include a plurality of sealing portions.

[0141] Specifically, the second chamber (41b) may include a first sealing part (81) that prevents air from moving between the inside of the fixed body (432) and the rotating body (441).

[0142] The first sealing portion (81) may be provided to be compressed between the support portion (445) and the fixed body (432). That is, the sealing portion (81) is compressed by the weight of the filter portion (43) to prevent air from moving between the inside of the fixed body (432) and the rotating body (441).

[0143] If the first sealing part (81) is not provided inside the second chamber (41b), foreign matter collected in the collection space (412) can be moved between the inside of the fixed body (432) and the rotating body (441).

[0144] Consequently, foreign substances collected in the collection space (412) can move to the exhaust section (153) through the space between the inside of the fixed body (432) and the rotating body (441) without passing through the first filter (431). Air containing foreign substances can be discharged into the indoor space.

[0145] Accordingly, the first sealing part (81) ensures that the air discharged through the discharge part (153) must pass through the filter (431, 422) to separate foreign substances, thereby maintaining the air quality of the indoor space in a pleasant state. In addition, the first sealing part (81) prevents fine foreign substances from scattering when the vacuum cleaner (100) is operated, thereby maintaining the airflow.

[0146] Additionally, the second chamber (41b) may include a second sealing part (82) that prevents air from moving between the withdrawal body (433) and the first body (421).

[0147] The second sealing part (82) above can prevent air passing through the chamber forming part (42) from passing through the first filter (431) and moving between the withdrawal body (433) and the first body (421) to be discharged through the outlet (153).

[0148] If the second sealing part (82) is not provided, the air passing through the chamber forming part (42) can be moved between the extraction body (433) and the first body (421).

[0149] The air passing through the chamber forming part (42) may have only large particles of foreign matter removed, and small particles of fine foreign matter may not be removed.

[0150] As a result, fine foreign matter can move to the exhaust section (153) through the space between the extraction body (433) and the first body (421) without passing through the first filter (431). Air containing fine foreign matter can be discharged into the indoor space.

[0151] Accordingly, the second sealing part (82) ensures that the air discharged through the discharge part (153) must pass through the filter (431, 422) to separate foreign substances, thereby maintaining the air quality of the indoor space in a pleasant state.

[0152] Additionally, the second chamber (41b) may include a third sealing part (83) that prevents air from moving between the cover (18) and the bottom surface of the second body (423).

[0153] The above third sealing part (83) can prevent the lower space of the first chamber (41a) and the lower space (collection space) of the second chamber (41b) from communicating.

[0154] If the third sealing part (83) is not provided, fine foreign matter collected in the collection space (412) can move to the lower space of the first chamber (41b).

[0155] Fine foreign matter that has moved to the lower space of the first chamber (41a) can be prevented from scattering and being discharged to the intake part (11), etc., during the operation of the vacuum cleaner (100).

[0156] Accordingly, the third sealing part (83) ensures that the air discharged through the discharge part (153) must pass through the filter (431, 422) to separate foreign substances, thereby maintaining the air quality of the indoor space in a pleasant state.

[0157] Additionally, the second chamber (41b) may include a fourth sealing part (84) that prevents air from moving between the cover (18) and the rotating plate (9). The fourth sealing part (84) is described below.

[0158] As illustrated in FIG. 7, the vacuum cleaner (100) may include a rotating plate (9) that is coupled to the cover (18) and is rotatably provided in at least a portion so as to rotate the foreign matter removal part (44).

[0159] Additionally, the rotating plate (9) may include a rotating handle (91) that provides rotational power to the foreign matter removal unit (44).

[0160] The above-mentioned rotating plate (9) can be coupled to the lower part of the above-mentioned cover (18).

[0161] Specifically, the rotating plate (9) may be provided as part of the exterior of the vacuum cleaner (100). The diameter of the rotating plate (9) may be smaller than the diameter of the cover (18). Additionally, the rotating plate (9) may be provided in a recessed groove of the cover (18). That is, the rotating plate (9) may be provided in various forms as long as it can be rotated outside the vacuum cleaner (100).

[0162] The above-mentioned rotating handle (91) may be provided on the lower part of the rotating plate (9). That is, the rotating handle (91) may be provided to protrude from the rotating plate (9) so as to be able to rotate the foreign matter removal part (44). However, the rotating handle (91) may be provided in various forms as long as it can rotate the foreign matter removal part (44).

[0163] The operation method of the above-mentioned rotating plate (9) will be explained in detail below.

[0164] As illustrated in FIGS. 6 and 7, the rotating plate (9) can be combined with the foreign substance removal unit (44). That is, if the user directly applies rotational force to the rotating plate (9), the foreign substance removal unit (44) can rotate and separate foreign substances attached to the first filter (431).

[0165] That is, the user can conveniently separate foreign substances attached to the first filter (431) by gripping the rotating handle (91) and rotating the rotating plate (9).

[0166] The above-mentioned rotating plate (9) can not only provide rotational force directly to the user, but can also automatically provide rotational force through a power transmission device (not shown).

[0167] For example, when the above vacuum cleaner (100) is placed on the vacuum cleaner station, the power transmission device can rotate the above rotating plate (9) to rotate the foreign matter removal unit (44).

[0168] In conclusion, the rotating plate (9) can efficiently separate foreign substances attached to the first filter (431). Therefore, the lifespan of the first filter (431) can be improved, and pleasant air can be discharged into the indoor space.

[0169] The above fourth sealing part (84) can prevent air from moving between the cover (18) and the rotating plate (9).

[0170] As shown in FIG. 6, the fourth sealing part (84) can prevent foreign substances collected in the collection space (412) from being discharged to the outside (indoor space) through the space between the cover (18) and the rotating plate (9).

[0171] If the fourth sealing part (84) is not provided, fine foreign matter collected in the collection space (412) can be discharged to the outside through the space between the cover (18) and the rotating plate (9) without passing through the first filter (431).

[0172] Accordingly, the fourth sealing part (84) can guide the flow of air so that the air inside the second chamber (41b) passes through the filter (431, 422) and is discharged through the discharge part (153).

[0173] The present invention may be modified and implemented in various forms, and its scope of rights is not limited to the embodiments described above. Therefore, if a modified embodiment includes the components of the claims of the present invention, it should be considered to fall within the scope of rights of the present invention.
