No. 16/893,215, filed on Jun. 4, 2020, which claims the benefit of the Korean Patent Application No. 10-2019-0066843 filed on Jun. 5, 2019, Korean Patent Application No. 10-2019-0078898 filed on Jul. 1, 2019, Korean Patent Application No. 10-2020-0003103 filed on Jan. 9, 2020, Korean Patent Application No. 10-2020-0003105 filed on Jan. 9, 2020, Korean Patent Application No. 10-2020-0003106 filed on Jan. 9, 2020, which are hereby incorporated by reference as if fully set forth herein. 
    
    
     BACKGROUND 
     Field 
     The present disclosure relates to a cleaner. 
     Related Art 
     A cleaner is a device that performs cleaning by suctioning or wiping dust or foreign substances located in a cleaning target area. 
     Such a cleaner may be classified as a manual cleaner which requires a user to directly move the cleaner, and an automatic cleaner that drives on its own and does not require a user to manually move the cleaner. 
     In addition, the manual cleaner may be classified as, e.g., a canister type cleaner, an upright type cleaner, a handy type cleaner, a stick type cleaner, etc. 
     For example, US Patent Publication No. US2018/0132685A1 discloses a compression mechanism having a dust compression part compressing dust in a dust bin. 
     The compression mechanism may include a dust bin having an opening, a filter purifying air in the dust bin, a shroud surrounding the filter, a dust compression part disposed to surround the shroud, a handle operated by a user to move the dust compression part, and a link connected to the handle. 
     When the dust compression part is lowered by an operation force of the handle transferred thereto through the link, the dust compression part compresses dust in the dust bin. 
     However, according to the related art document, at least a portion of the dust compression part is located higher than the opening at a standby position, and thus the dust compression part is accommodated in the dust bin without guiding a flow of air. 
     Therefore, an internal space of the dust bin is reduced by a thickness of the dust compression part, resulting in a reduction in the space for separating dust. 
     In addition, a lower surface of the dust compression part compresses the dust stored in the dust bin, and here, if the dust compression part is located higher than the opening, a distance for the dust compression part to vertically move for compressing the dust is reduced to result in a reduction in dust compression performance. 
     Because the dust compression part moves in contact with an inner circumferential surface of the dust bin, the inner circumferential surface of the dust bin may be cleaned, but there is a possibility that dust may be caught between the dust compression part and the inner circumferential surface of the dust bin, and in this case, a vertical movement of the dust compression part is not smooth. 
     In particular, when the dust compression part is lowered and rises in the process of suctioning air and dust through the opening, there is a problem that dust accumulates on an upper side of the dust compression part. 
     When the amount of dust accumulated on the upper side of the dust compression part is large, a vertical movement of the dust compression part is not smooth and the dust compression part may not be able to move to a standby position and block the opening. 
     SUMMARY 
     The present disclosure provides a cleaner in which air and dust suctioned through the suction opening fall into a dust bin even when a movable part is operated downward in a process of operating the cleaner. 
     The present disclosure provides a cleaner in which, even if dust is present on an upper side of a movable part in a lifted state after the movable part is moved to a lower side, the dust present on the upper side of the movable part may easily fall to the dust bin by air suctioned through the suction opening. 
     The present disclosure provides a cleaner in which air passing through a suction opening at a standby position of a movable part is prevented from directly moving to an air flow path. 
     To achieve these and other advantages and in accordance with the purpose of the disclosure, as embodied and broadly described herein, there is provided a cleaner including a housing including a suction opening, a cyclone part configured to separate dust from air introduced through the suction opening, and a dust bin configured to store the dust separated at the cyclone part; and a movable part configured to be movable between a first position and a second position in the housing. 
     The movable part may include a frame disposed to surround an axis of a cyclone flow of the cyclone part at the first position. The frame may include an air flow path through which air flows so that dust accumulated in the frame falls from the movable part in the process of moving to the second position or returning from the second position to the first position. 
     In one embodiment, the frame may include a first body facing the suction opening at the first position and inclined at a first angle with respect to a horizontal plane and a second body extending from the first body and inclined at a second angle smaller than the first angle with respect to the horizontal plane. The second body may form the air flow path through which air introduced through the suction opening flows. 
     A bottom surface of the second body may define a lower portion of the air flow path. The bottom surface of the second body may be lowered in a circumferential direction. Dust in the air flow path may flow downward, while flowing in the circumferential direction. 
     A height of the air flow path may increase in a direction away from the first body, so that a width through which dust flows is secured so that dust may easily flow through the air flow path. 
     The frame may further include an extension wall extending upward from an outer end of the second body to define the air flow path. The air flow path may spirally flow by the extension wall. 
     The frame may further include a third body extending in the circumferential direction from the second body and inclined at a third angle with respect to the horizontal plane. 
     The first body may be inclined to the outside upward from a lower side toward an upper side and the third body may be inclined to the outside downward from the upper side toward the lower side, so that dust may move downward along the third body. 
     The frame may further include a fourth body extending in the circumferential direction from the third body and inclined at a fourth angle with respect to the horizontal plane, wherein the fourth angle may be greater than the third angle. 
     A radius of an outer end of the fourth body based on the center of the frame may be smaller than a radius of an outer end of the first body. 
     A distance between the fourth body and an inner circumferential surface of the housing is larger than a distance between the first body and the inner circumferential surface of the housing, and thus dust on the air flow path may fall downward through a space between the fourth body and the inner circumferential surface of the housing. 
     Alternatively, the frame may include a third body extending from the second body so that air or dust flowing through the air flow path falls downward. 
     A distance between a point of the third body and the inner circumferential surface of the housing may be greater than a distance between the second body and the inner circumferential surface of the housing. 
     The frame may further include a fourth body extending from the third body, an inclination angle of the fourth body with respect to the horizontal plane may be greater than an inclination angle of the third body, and a distance between one point of the fourth body and the inner circumferential surface of the housing may be greater than the distance between the third body and the inner circumferential surface of the housing. 
     The cleaner may further include an air guide located in the housing, wherein the frame may be disposed to surround the air guide at the first position. 
     The air guide may include a guide wall disposed to surround the axis of the cyclone flow, the first body may be in contact with the guide wall, and at least a portion of the second body may be spaced apart from the guide wall and the air flow path may be located in a space between the guide wall and the second body. 
     The first body may be disposed to face the suction opening, so that air introduced through the suction opening may be prevented from flowing directly to the air flow path. 
     The cleaner may further include a filter part configured to filter dust from the air introduced through the suction opening in the housing. 
     The movable part may further include a cleaning part coupled to the frame and configured to clean the filter part when moving between the first position and the second position. 
     The frame body may further include a third body extending from the second body and a fourth body extending from the three body so that air or dust flowing through the air flow path may smoothly fall downward. 
     A distance between the fourth body and the inner circumferential surface of the housing may be greater than a distance between the third body and the inner circumferential surface of the housing. 
     With respect to the horizontal plane, the third body may be inclined at a third angle and the fourth body may be inclined at a fourth angle greater than the third angle. 
     In another embodiment of the present disclosure, there is provided a cleaner including a housing including a suction opening; a filter part configured to filter dust from air introduced through the suction opening and spaced apart from an inner circumferential surface of the housing; an air guide configured to guide the air passing through the filter part to a suction motor for generating a suction force; and a movable part configured to be movable between a first position and a second position in the housing.

     The main body  2  may be formed in a cylindrical shape, for example, and an outer shape thereof may be formed by a plurality of housings. 
     In one embodiment, the main body  2  may include a first housing  10  having a substantially cylindrical shape and a second housing  12  coupled to an upper side of the first housing  10  and having a substantially cylindrical shape. 
     An upper portion of the first housing  10  may define the first cyclone part  110 , and a lower portion of the first housing  10  may define a dust bin  112  for storing dust separated from the first cyclone part  110 . The dust bin  112  may include a first dust storage  120  storing dust separated from the first cyclone part  110 . 
     A lower side of the first housing  10  (e.g., a lower side of the dust bin  112 ) may be opened and closed by a housing cover  114  that rotates by a hinge. 
     To seal a boundary between the first housing  10  and the second housing  12  in a state where the first housing  10  and the second housing  12  are coupled, the cleaner  1  may further include a sealing member  16  and a support body  14  supporting the sealing member  16 . 
     Upper and lower sides of each of the first housing  10  and the second housing  12  are open. That is, each of the housings  10  and  12  may include an upper opening and a lower opening. 
     The support body  14  may be formed in a cylindrical shape. Here, an outer diameter of the support body  14  may be the same as or less than an inner diameter of the first housing  10  so that the support body  14  may be inserted into the first housing  10  through the upper opening of the first housing  10 .

     The sealing member  16  may be coupled to the support body  14  to surround an outer circumferential surface of the support body  14 . For example, the sealing member  16  may be integrally formed with the support body  14  by an insert injection molding process. Alternatively, the sealing member  16  may be coupled or adhered to the outer circumferential surface of the support body  14 , such as by an adhesive. 
     The main body  2  may include a suction opening  12   a  through which air guided through the suction part  5  passes or flows through. 
     One of the first housing  10  and the second housing  12  may include the suction opening  12   a , or the first housing  10  may form a part of the suction opening  12   a  and the second housing  12  may form another part of the suction opening  12   a.    
     Hereinafter, an embodiment in which the second housing  12  includes the suction opening  12   a  will be described. 
     When the second housing  12  is coupled to the first housing  10 , the suction opening  12   a  of the second housing  12  and the communication opening  15  of the support body  14  are aligned. 
     The suction opening  12   a  is aligned with the suction part  5 . With such configuration, dust and air may be introduced into the first cyclone part  110  through the inside of the suction part  5 , the suction opening  12   a , and the communication opening  15 . 
     In this embodiment, the support body  14  may be omitted. In this embodiment, an upper end of the first housing  10  may be in direct contact a lower end of the second housing  12 . In addition, dust and air may flow into the first cyclone part  110  through the suction opening  12   a  after passing through the inside of the suction part  5 . 
     In the present disclosure, a configuration for guiding air from the suction part  5  to the first cyclone part  110  may be referred to as a suction passage of the main body  2 . 
     Accordingly, the suction passage may include only the suction opening  12   a  or may include the suction opening  12   a  and the communication opening  15 . 
     The main body  2  may further include a filter part  130  disposed to surround the second cyclone part  140 . 
     The filter part  130  may be formed in a cylindrical shape, for example, and guide air separated from dust in the first cyclone part  110  to the second cyclone part  140 . The filter part  130  filters dust from air in the process in which air flows or passes there through. 
     The filter part  130  may be arranged to surround an axis A 1  of a cyclone flow of the first cyclone part  110 . 
     To this end, the filter part  130  may include a mesh portion  132  having a plurality of holes. The mesh portion  132  may be formed of a metal material but is not limited thereto. Since the mesh portion  132  filters air, dust may accumulate on the mesh portion  132 , and thus the mesh portion  132  may need to be cleaned. 
     In the present disclosure, the cleaner  1  may further include a compression mechanism  70  capable of compressing dust stored in the first dust storage  120 . 
     Since capacity of the first dust storage  120  is limited, the amount of dust stored in the first dust storage  120  may accumulate during repeated cleaning, and thus a usage time of and the number of times the cleaner is used may be limited. 
     The user may cause or manipulate the housing cover  114  to open the first dust storage  120  in order to remove dust of the first dust storage  120 . 
     In this embodiment, when dust stored in the first dust storage  120  is compressed using the compression mechanism  70 , density of the dust stored in the first dust storage  120  increases, and thus a volume thereof decreases. 
     Therefore, according to the present embodiment, the number of times for emptying the dust bin  112  is reduced, and accordingly, requiring less frequent emptying of the dust bin. 
     The compression mechanism  70  may also clean the mesh portion  132  during a movement process. 
     The compression mechanism  70  may include a movable part  750  movable in the main body  2 , an operating part  710  (or manipulating part) operated by the user to move the movable part  750 , and transfer parts  720  and  730  transferring an operation force of the operating part  710  to the movable part  750 . 
     The movable part  750  may be form in a ring-like shape, for example, such that interference with a structure provided in the first dust storage  120  may be prevented. The operating part  710  may have a structure that the user may manually press. 
     The operating part  710  may be disposed outside the main body  2 . For example, the operating part  710  may be located outside the first housing  10  and the second housing  12 . 
     At least a portion of the operating part  710  may be located above the first housing  10 . Also, at least a portion of the operating part  710  may be located above the movable part  750 . 
     The operating part  710  may include a pressing part  714 . The pressing part  714  may be located above the first housing  10  and the movable part  750 . 
     The operating part  710  may include an operating part body  712 . The operating part body  712  may have a vertical length that is longer than a horizontal width thereof. The pressing part  714  may protrude from an upper portion of the operating part body  712 . 
     The pressing part  714  may protrude in the horizontal direction from the operating part body  712  in a state where the operating part body  712  is disposed in a vertical direction. 
     In one embodiment, the pressing part  714  may be located closer to an upper end than a lower end of the operating part body  712 . The pressing part  714  may protrude from a position spaced apart downward from the upper end of the operating part body  712 . 
     The pressing part  714  may include a first portion  714   a  protruding from the operating part body  712  and a second portion  714   b  additionally protruding from the first pressing part  714   a.    
     The second portion  714   b  may protrude from a position spaced apart by a predetermined distance in a downward direction from an upper end  714   c  of the first portion  714   a.    
     The user may move the operating part  710  in a downward direction by pressing an upper surface  714   d  of the second portion  714   b . Therefore, an upper surface  714   d  of the second portion  714   b  may function as a pressing surface. 
     The operating part  710  may further include a coupling projection (See  716  of  FIG. 6 ) located on the opposite side of the pressing part  714  in the operating part body  712 . 
     The handle part  3  may include a handle body  30  for the user to grip or manipulate and a battery housing  60  disposed below the handle body  30  and accommodating a battery  600 . 
     The handle body  30  and the battery housing  60  may be disposed in an up-down direction, and the handle body  30  may be located above the battery housing  60 . 
     The handle part  3  may guide movement of the operating part  710 , while covering a portion of the operating part  710 . 
     In one embodiment, the handle part  3  may further include an operating part cover  62 . The operating part cover  62  may be located on the side of the handle body  30  and the battery housing  60 . 
     The operating part cover  62  may be formed integrally with the handle body  30  and the battery housing  60  or may be formed separately from the handle body  30  and the battery housing  60 . 
     If the operating part cover  62  is formed separately from the handle body  30  and the battery housing  60 , the operating part cover  62  may be coupled to the main body  2 . 
     In a state where the user grips the handle body  30  by a right hand, the operating part  710  may be located on the left of the handle body  30 . Of course, in a state where the user grips the handle body  30  by a left hand, the operating part  710  may be located on the right of the handle body  30 . With such configuration, the user may more easily operate the operating part  710  by a hand that does not grip the handle body  30 . 
     The operating part  710  may move in a direction parallel to the axis A 1  of the cyclone flow of the first cyclone part  110 . 
     For example, the axis A 1  of the cyclone flow of the first cyclone part  110  may extend in the up-down direction in a state where the dust bin  112  is placed on the floor. Therefore, the operating part  710  may also be moved in the up-down direction in a state where the dust bin  112  is placed on the floor. 
     A slot  63  may be provided on the operating part cover  62  for movement of the operating part  710 . The pressing part  714  of the operating part  710  may penetrate the slot  63 . 
     A vertical length of the operating part body  712  may be longer than a vertical length of the slot  63 . A horizontal width of the operating part body  712  may be longer than a horizontal width of the slot  63 . 
     The horizontal width of the pressing part  714  may be the same as or less than the horizontal width of the slot  63 . The vertical length of the pressing part  714  may be less than the vertical length of the slot  63 . 
     A protruding length of the pressing part  714  may be longer than a front-rear width of the operating part cover  62 . Therefore, the pressing part  714  may penetrate the slot  63  and may protrude outside the operating part cover  62  through the slot  63 . 
     The horizontal width of the operating part body  712  may be less than the horizontal width of the operating part cover  62 . The vertical length of the operating part body  712  may be less than the horizontal width of the operating part cover  62 . 
     A front-rear width of the operating part body  712  may be less than a front-rear width of the operating part cover  62 . The operating part cover  62  may form a space for the operating part body  712  to locate. The operating part body  712  may move in the up-down direction in a state where the operating part body  712  is located in the operating part cover  62 . 
     In the operating part cover  62 , the operating part body  712  may move between the first position and the second position. 
     For example, the first position is a position when the operating part body  712  has moved to the top, and the second position is a position when the operating part body  712  has moved to the bottom. 
     In a state where no external force is applied to the operating part  710 , the operating part body  712  may be located at the first position. The operating part body  712  may cover the slot  63  in a state where the operating part body  712  is located at the first position. 
     In one embodiment, in a state where the operating part body  712  is located at the first position, the operating part body  712  may fully cover the slot  63  inside the operating part cover  62 . Accordingly, in a state where the operating part body  712  is located at the first position, the operating part body  712  may be exposed to the outside of the slot  63  and a space inside the operating part cover  62  may be prevented from being exposed. 
     The slot  63  may also extend in a direction parallel to the extending direction of the axis A 1  of the cyclone flow of the first cyclone part  110 . 
     In this embodiment, since the extending direction of the axis A 1  of the cyclone flow is the up-down direction, for example, the “up-down direction” described below may be understood as the extending direction of the axis A 1  of the cyclone flow. 
     Since the movable part  750  is located in the main body  2 , the operating part  710  is located outside the main body  2 , one portion of the transfer parts  720  and  730  may be located outside the main body  2  and the other portion thereof may be located inside the main body  2  to connect the movable part  750  and the operating part  710 . 
     Portions of the transfer parts  720  and  730  may penetrate the main body  2 . Portions of the transfer parts  720  and  730  located outside the main body  2  may be covered by the handle part  3 . 
     The transfer parts  720  and  730  may include a first transfer part  720 . The first transfer part  720  may be coupled to the operating part  710 . For example, the first transfer part  720  may include a coupling projection  722 . The coupling projection  722  may be coupled to a projection coupling part (not shown) formed at the operating part body  712 . 
     The coupling projection  722  may be formed to have a vertical length larger than a horizontal width thereof. The coupling projection  722  may restrict relative rotation of the operating part  710  with respect to the first transfer part  720  in a horizontal direction. 
     The transfer parts  720  and  730  may further include a second transfer part  730  coupled with the movable part  750 . A portion of the second transfer part  730  may be located inside the main body  2  and the other portion thereof may be located outside the main body  2 . 
     The second transfer part  730  may be directly connected to the first transfer part  720  or may be connected by an additional transfer part. 
     For example,  FIG. 3  illustrates an embodiment where the second transfer part  730  is directly connected to the first transfer part  720 . The first transfer part  720  may include a coupling part  724  to which the second transfer part  730  may be coupled. 
     The second transfer part  730  may extend in a direction parallel to the axis A 1  of the cyclone flow. 
     In the case of this embodiment, although not limited thereto, the center of the movable part  750  may be located on the axis A 1  of the cyclone flow or a vertical line passing through the center of the movable part  750  may be parallel to the axis A 1  of the cyclone flow. 
     In this embodiment, the operating part  710  is disposed at a position eccentric from the center of the movable part  750 . Therefore, eccentricity of the movable part  750  should be prevented in the process in which the movable part  750  moves up and down by the operation of the operating part  710 . 
     If the movable part  750  moves up and down in an eccentric state, the movable part  750  may not form a horizontal state and may not move smoothly and the movable part  750  may not move accurately to the standby position. 
     When the transfer part for transferring an operation force of the operating part  710  to the movable part  750  includes one transfer part, a possibility that the movable part  750  is eccentric in the process of operating the operating part  710  is high. 
     For example, when the operating part  710  is directly connected to the movable part  750  or connected by a single transfer part, a path through which the operation force of the operating part  710  is transferred to the movable part  750  is relatively short. 
     If the operating part  710  is operated in an eccentric state with respect to a vertical line, the effect of eccentricity of the operating part  710  may directly act on the movable part  750  so there is a greater possibility that the movable part  750  is moved in the eccentric state. 
     However, as in the present disclosure, when the transfer part includes a plurality of transfer parts and transfers the operation force of the operating part to the movable part  750 , even if the operating part  710  is eccentric with respect to the vertical line in the process of operating the operating part  710 , the plurality of transfer parts may reduce the influence of the eccentric to minimize the amount of eccentricity of the movable part  750 . 
     The main body  2  may further include a protruding body  180  for guiding the second transfer part  730 . The protruding body  180  is, for example, present in a form protruding from the outside of the first housing  10 . 
     The protruding body  180  may extend in a direction parallel to the extending direction of the axis A 1  of the cyclone flow of the first cyclone part  110 . 
     The protruding body  180  communicates with an internal space of the first housing  10 , and the second transfer part  730  may move in the protruding body  180 . 
     The cleaner  1  may further include a support mechanism  780  elastically supporting the compression mechanism  70 . 
     The support mechanism  780  may include an elastic member  781  providing an elastic force to the compression mechanism  70 . The elastic member  781  may provide the elastic force to the operating part  710  or the transfer parts  720  and  730 . Hereinafter, an embodiment where the elastic member  781  supports the operating part  710  will be described. 
     The elastic member  781  may be disposed spaced apart from the second transfer part  730  in the horizontal direction. The elastic member  781  may be, for example, a coil spring and may be expanded and contracted in the up-down direction—but is not limited to such mechanism. 
     Here, at the first position of the operating part  710  (the position of the operating part  710  before the user presses the operating part  710 ), a length of the elastic member  781  may be longer than a length of the second transfer part  730 . 
     When the length of the elastic member  781  is longer than the length of the second transfer part  730 , the operating part  710  may be supported using the elastic member  781  having a low modulus of elasticity. 
     In this case, a required force may be reduced when pressing the operating part  710 . In addition, when the operating part  710  is returned to its original position by the elastic member  781 , noise that may occur as the upper end  714   c  of the first portion  714   a  in the pressing part  714  collides with a surface forming the slot  63  of the operating part cover  62  may also be reduced. 
     The support mechanism  780  may further include a support bar  790  supporting the elastic member  781  so that a horizontal movement of the elastic member  781  is limited in the vertical movement process of the operating part  710 . 
     The support bar  790  may be formed in a cylindrical shape (not limited thereto). A vertical length of the support bar  790  may be longer than a vertical length of the elastic member  781 . 
     The elastic member  781  may be disposed to surround the support bar  790 . That is, the support bar  790  may be located at an inner region of the coil-shaped elastic member  781 . An outer diameter of the support bar  790  may be to the same as or smaller than an inner diameter of the elastic member  781 . 
     One end of the support bar  790  may be coupled to the main body  2  or a transfer part cover, which will be described later. The first transfer part  720  may be coupled to the other end of the support bar  790 . 
     Here, the support bar  790  may be coupled to the first transfer part  720  after passing through the coupling projection (See  716  in  FIG. 6 ). A portion of the coupling projection (See  716  in  FIG. 6 ) may be coupled to the first transfer part  720 . 
     The upper end of the elastic member  781  may contact the lower side of the coupling projection (see  716  in  FIG. 6 ). 
     The other end of the support bar  790  may be an upper end. The upper end of the support bar  790  may be coupled to penetrate the first transfer part  720 . 
     The first transfer part  720  may move up and down along the support bar  790 . Accordingly, the support bar  790  may guide a vertical movement of the first transfer part  720 . Therefore, the support bar  790  may be referred to as a guide bar. 
     The cleaner  1  may further include a transfer part cover  64  covering the transfer parts  720  and  730 . 
     The transfer part cover  64  may be coupled to the main body  2  in a state of covering the transfer parts  720  and  730 . The operating part cover  62  may cover at least a portion of the transfer part cover  64 . In this embodiment, the transfer part cover  64  may be omitted and the operating part cover  62  may function as the transfer part cover  64 . 
     The transfer part cover  64  may also cover the support mechanism  780 . 
     The first portion  641  of the transfer part cover  64  may cover the first transfer part  720 , the support bar  790 , and the elastic member  781  at the side of the protruding body  180 . 
     The second portion  644  of the transfer part cover  64  may be located above the protruding body  180  and may cover the second transfer part  730 . 
     The transfer part cover  64  may include a slot  642  at which the coupling projection  722  of the first transfer part  720  is located. The slot  642  may extend in the up-down direction. 
     The transfer part cover  64  may have a bar coupling part  645  to which the support bar  790  may be coupled. 
     Meanwhile, the main body  2  may further include a suction motor  220  for generating a suction force. The suction force generated by the suction motor  220  may act on the suction part  5 . The suction motor  220  may be located in the second housing  12 , for example. 
     The suction motor  220  may be located above the dust bin  112  and the battery  600  with respect to the extending direction of the axis A 1  of the cyclone flow of the first cyclone part  110 . 
     The main body  2  may further include an air guide  170  guiding air passing or flowing through the filter part  130  to the suction motor  220 . 
     In one example, the air guide  170  may guide air discharged from the second cyclone part  140  to the suction motor  220 . 
     The second cyclone part  140  may be coupled to a lower side of the air guide  170 . The filter part  130  may surround the second cyclone part  140  in a state of being coupled to the second cyclone part  140 . 
     Therefore, the filter part  130  may also be located below the air guide  170 . The movable part  750  may be disposed at a position surrounding the air guide  170  in a standby position. 
     The movable part  750  may include a cleaning part  770  for cleaning the filter part  130 . 
     In this embodiment, a position of the movable part  750  in a state where the operating part  710  is not operated (an initial position of the operating part  710 ) may be referred to as a standby position (or the first position). That is, the position of the movable part  750  when the operating part  710  is located at the first position may be referred to as the standby position. A position of the movable part  750  when the operating part  740  is located at the second position may be referred to as a dust compression position (or the second position). 
     At the standby position of the movable part  750 , the entirety of the cleaning part  770  may be disposed not to overlap the filter part  130  in a direction in which air passes through the filter part  130 . For example, at the standby position of the movable part  750 , the entirety of the cleaning part  770  may be located above the filter part  130 . Accordingly, at the standby position of the movable part  750 , the cleaning part  770  may be prevented from acting as a flow resistance in the process in which air passes through the filter part  130 . 
     A dust guide  160  may be provided below the second cyclone part  140 . A lower side of the second cyclone part  140  may be coupled to an upper side of the dust guide  160 . In addition, a lower side of the filter part  130  may be seated or accommodated on the dust guide  160 . 
     The lower side of the dust guide  160  may be seated or accommodated on the housing cover  114 . The dust guide  160  is spaced apart from the inner circumferential surface of the first housing  10  and divides or separates an internal space of the first housing into a first dust storage  120  storing dust separated at the first cyclone part  110  and a second dust storage  122  storing dust separated at the second cyclone part  140 . 
     The inner circumferential surface of the first housing  10  and the outer circumferential surface of the dust guide  160  may define or form the first dust storage  120 , and the inner circumferential surface of the dust guide  160  may define or form the second dust storage  122 . 
     Hereinafter, the compression mechanism  70  will be described in more detail. 
       FIGS. 6 and 7  are perspective views of a compression mechanism according to an embodiment of the present disclosure.  FIG. 8  is an exploded perspective view of a movable part according to an embodiment of the present disclosure.  FIG. 9  is an exploded perspective view of a movable part according to an embodiment of the present disclosure.  FIG. 10  is a cross-sectional view taken along line  10 - 10  of  FIG. 8 . 
     Referring to  FIGS. 6 to 10 , the movable part  750  may include a frame  760 . 
     The frame  760  may be disposed to surround the axis A 1  of the cyclone flow. The frame  760  may be formed in a ring-like shape around the axis A 1  of the cyclone flow. 
     The frame  760  may compress dust stored in the first dust storage  120 . Therefore, the frame  760  may have sufficient rigidity for preventing deformation during a pressing process, while effectively compressing dust during the process of compressing dust. For example, the frame  760  may be an injection-molded material or may be formed of a metal material (not limited to any particular material). 
     A maximum diameter of the frame  760  may be less than a diameter of an inner circumferential surface of the first cyclone part  110 . Therefore, the frame  760  may be moved up and down in a state of being spaced apart from the inner circumferential surface of the first cyclone part  110 . 
     In the present embodiment, even if the movable part  750  moves up and down in an eccentric state, frictional contact of the movable part  750  with the inner circumferential surface of the first housing  10  (e.g., the first cyclone part  110  and/or dust bin  112 ) may be prevented. 
     In addition, when the frame  760  is spaced apart from the inner circumferential surface of the first cyclone part  110 , air and dust suctioned into the first cyclone part  110  may flow downward through the inner circumferential surface of the first cyclone part  110  and the frame  760  in a state where the movable part  750  has moved downward during the cleaning process. 
     The frame  760  may support the cleaning part  770 . The cleaning part  770  may be formed of an elastically deformable material. For example, the cleaning part  770  may be formed of a rubber material (not limited thereto). 
     The cleaning part  770  may be formed in a ring-like shape so that the cleaning part  770  may clean the entirety of the circumference of the cylindrical filter part  130  may be reduced or prevented. As another example, the cleaning part  770  may be formed of silicone or a fiber material. 
     When the cleaning part  770  is formed of an elastically deformable material, damage to the filter part  130  when the cleaning part  770  is in frictional contact with the filter part  130 . 
     The movable part  750  may move from the standby position to a dust compression position. 
     The cleaning part  770  may standby at a position outside the filter part  130  at the standby position, and during a dust compression process, the cleaning part may wipe the outer surface of the filter part  130 , while moving to the dust compression position. 
     The cleaning part  770  may include a cleaning end  771   a . The cleaning end  771   a  may be in contact with the outer surface of the filter part  130  during the cleaning process. 
     In the present embodiment, since the cleaning part  770  is formed of an elastically deformable material, when the cleaning part is lowered and the cleaning end  771   a  comes into contact with the filter part  130 , the cleaning part  770  may be elastically deformed outward in a radial direction of the filter part  130 , and in the elastically deformed state, the cleaning end  771   a  may come into contact with the filter part  130 . 
     Therefore, when the cleaning end  770  is lowered in a state where the cleaning end  771   a  is in contact with the circumference of the filter part  130 , the cleaning end  771   a  removes dust adhered to the outer surface of the filter part  130 . 
     In the present embodiment, since the cleaning end  771   a  is moved in contact with the filter part  130 , the cleaning part  770  may reduce eccentricity of the movable part  750  in the vertically moving process. 
     In one example, in a state where the movable part  750  is inclined with respect to a horizontal direction, a contact force between a portion of the cleaning end  771   a  and the filter part  130  increases, so that the cleaning end  771   a  is deformed and inclination of the movable part  750  may be reduced. 
     The cleaning part  770  may include a first part  771  and a second part  772  extending upward from the first part  771 . 
     A thickness of the second part  772  may be less than a thickness of the first part  771 . The second part  772  may be coupled to a lower side of the frame  760 . 
     For example, the cleaning part  770  may be coupled to the frame  760  by an insert injection molding process. 
     The cleaning part  770  may further include a depressed portion  773  recessed in a downward direction from the upper end. A lower extending portion  761   a  extending from the frame  760  may be located in the depressed portion  773 . The lower extending portion  761   a  located in the depressed portion  773  may be aligned with the suction opening  12   a.    
     The frame  760  may include a frame body  761  supporting the cleaning part  770 . 
     At the standby position, a portion of the frame body  761  may be in contact with the outer surface of the air guide  170 . A portion of the frame body  761  may surround an outer surface of the air guide  170  in a circumferential direction. 
     The frame  760  may further include a lower extension wall  766  extending in a downward direction from the frame body  761 . The lower extension wall  766  may be rounded in the circumferential direction of the frame  760 . 
     The lower extension wall  766  may function to press dust stored in the dust bin  112  in a downward direction while the movable part  750  is lowered. The lower extension wall  766  may be located, for example, at a portion where the outer wall  763  is formed at the frame body  761 . 
     The frame  760  may further include a coupling part  767  extending outward from the lower extension wall  766 . 
     The coupling part  767  may protrude in the horizontal direction from the lower extension wall  766 . For example, the coupling part  767  may extend in a horizontal direction from a lower end  766   a  side of the lower extension wall  766 . Accordingly, since the portion to which the operation force transferred from the transfer part is applied first acts on the lower extension wall  766 , which is a position spaced apart from the frame body  761 , eccentricity of the frame body  761  may be reduced. 
     In addition, in the present embodiment, since the coupling part  767  is located on the lower end  766   a  side of the lower extension wall  766 , an increased in height of the cleaner  1  is prevented while a vertical movement stroke of the movable part  750  may increase. 
     That is, as the distance between the coupling part  767  and the pressing portion  714  of the operating part  710  increases, the vertical movement stroke of the movable part  750  may increase. When the vertical movement stroke of the movable part  750  increases, compression performance of dust stored in the first dust storage  120  may be improved. 
     The second transfer part  730  may be connected to the coupling part  767 . 
     A buffer part  734  may be coupled to the second transfer part  730 . The second transfer part  730  may be coupled to penetrate the buffer part  734 . The buffer part  734  may be seated on an upper surface of the coupling part  767  in a state where the buffer part  734  is coupled to the second transfer part  730 . 
     The second transfer part  730  may penetrate an upper wall of the protruding body  180 . 
     The buffer part  734  functions to absorb a shock (e.g., force with respect to time) that occurs when the movable part  750  comes into contact with the upper side wall of the protruding body  180  in the process of moving from the dust compression position to the standby position, and accordingly, the occurrence of noise may be reduced. 
     The frame  760  may further include a frame guide  765  extending in a downward direction from the frame body  761 . For example, the frame guide  765  may extend in a downward direction from an outer circumferential surface of the first body  762   a , which will be described later. 
     The frame guide  765  may include a planar guide surface  765   a . The guide surface  765   a  may guide a spiral flow of air in the process of air flowing through the suction part  5  (See  FIG. 26 ). The guide surface  765   a  may substantially be parallel to an extending line extending in a tangential direction of the first cyclone part  110 . 
     The lower end  765   b  of the frame guide  765  may be located below the contact end  771   a  of the cleaning part  770 . The lower end  766   a  of the lower extension wall  766  may be located below the lower end  765   a  of the frame guide  765 . 
     Hereinafter, the frame  760  will be described in detail. 
       FIG. 11  is a perspective view of the frame of  FIG. 9 , viewed from a direction “A”.  FIG. 12  is a side view of the frame of  FIG. 9 , viewed from a direction “B”.  FIG. 13  is a plan view of a frame according to an embodiment of the present disclosure.  FIG. 14  is a cross-sectional view taken along line  14 - 14  of  FIG. 13 .  FIG. 15  is a cross-sectional view taken along line  15 - 15  of  FIG. 13 .  FIG. 16  is a cross-sectional view taken along line  16 - 16  of  FIG. 13 .  FIG. 17  is a cross-sectional view taken along line  17 - 17  of  FIG. 13 .  FIG. 18  is a cross-sectional view taken along line  18 - 18  of  FIG. 13 . 
     Referring to  FIGS. 11 to 18 , the frame body  761  may include a first body  762   a . The first body  762   a  may surround an outer surface of the air guide  170 . 
     An outer end  762   a   1  (or upper end) of the first body  762   a  based on a radial direction in the frame bodies  761  may be located at the highest portion of the first body  762   a . The radial direction may be a direction perpendicular to the extending direction of the axis A 1  of the cyclone flow. 
     The first body  762   a  may be in contact with an outer surface of the air guide  170 , which will be described later. 
     Referring to  FIG. 14 , the first body  762   a  may be inclined by a first angle θ 1  with respect to a horizontal plane. When the first body  762   a  is inclined by the first angle θ 1 , a contact area between the first body  762   a  and dust stored in the first dust storage  120  may increase in a state where the movable part  750  has moved to the dust compression position, while air and dust suctioned through the suction part  5  may be guided in a downward direction. 
     When the contact area between the first body  762   a  and the dust stored in the first dust storage  120  increases, a compression area of the dust may increase to compress the dust stored in the first dust storage  120  overall, thereby improving dust compression performance by the movable part  750 . 
     The first body  762   a  may be inclined outward from the lower side to the upper side. Since the air suctioned through the suction part  5  may flow toward the outer surface of the first body  762   a , when the first body  762   a  is inclined outward from the lower side to the upper side, a lower flow of the suctioned dust may become relatively smooth. 
     An inclination angle of at least a portion of the first body  762   a  with respect to the horizontal plane in the circumferential direction of the frame body  761  may be constant. A portion in which the inclination angle is constant in the first body  762   a  may be in contact with the air guide  170 . 
     In addition, the air suctioned through the suction part  5  may smoothly flow in the circumferential direction along the portion where the inclination angle is constant in the first body  762   a . A radius R 1  of the outer end  762   a   1  of the first body  762   a  may be constant in the circumferential direction. Referring to  FIG. 13 , the first body  762   a  may extend by an angle A section based on a center O of the frame body  761 . 
     The frame body  761  may further include a second body  762   b  extending in the circumferential direction from the first body  762   a . The second body  762   b  may be inclined at an angle that is less than the first angle  81  with respect to the horizontal plane. Thus, as the second body  762   b  is inclined at the second angle  82 , a space may be formed between the air guide  170  and the second body  762   b  (See  FIG. 23 ). The space may act as an air flow path P. 
     For example, the inclination angle of the second body  762   b  with respect to the horizontal plane may be reduced in a direction away from the first body  762   a.    
     A height of the outer end of the second body  762   b  based on the radial direction may be lower in a direction away from the first body  762   a  than in a direction near the first body  762   a . Therefore, the second body  762   b  may guide the air and dust to flow in a downward spiral direction, while providing a flow path allowing air and dust to flow therethrough. 
     Referring to  FIG. 15 , a first portion  762   b   1  spaced apart by a first distance from the first body  762   a  in the second body  762   b  may be inclined by a second angle θ 2  with respect to the horizontal plane. The second angle θ 2  is smaller than the first angle θ 1 . 
     The outer end  762   b   11  (or upper end) of the first portion  762   b   1  may be located lower than the outer end  762   a   1  (or upper end) of the first body  762   a.    
     If the outer end  762   b   11  of the first portion  762   b   1  is located lower than the outer end  762   a   1  (or upper end) of the first body  762   a , a vertical gap between the second body  762   b  and the air guide  170  may be increased. 
     When the inclination angle of the first portion  762   b   1  is less than the inclination angle of the first body  762   a , the first portion  762   b   1  may be spaced apart from the air guide  170 . 
     Referring to  FIG. 16 , a second portion  762   b   2  spaced apart by the second distance from the first body  762   a  in the second body  762   b  may be substantially parallel to the horizontal plane. That is, the inclination angle of the second portion  762   b   2  may be 0 (zero) or greater than 0. That is, a portion of the second body  762   b  may be parallel to the horizontal plane. Here, the second distance is greater than the first distance. 
     The outer end  762   b   21  of the second portion  762   b   2  may be located lower than the outer end  762   b   11  of the first portion  762   b   1 . 
     A radius of the outer end of the second body  762   b  may be substantially equal to a radius R 1  of the upper end  762   a   1  of the first body  762   a.    
     Referring to  FIG. 13 , the second body  762   b  may extend by an angle B section based on the center O of the frame body  761 . The angle B is greater than the angle A. Therefore, in this embodiment, a circumferential length of the second body  762   b  is longer than a circumferential length of the first body  762   a.    
     The frame body  761  may further include a third body  762   c  extending from the second body  762   b.    
     Referring to  FIG. 17 , at a point of the third body  762   c , the third body  762   c  may be inclined at a third angle θ 3  with respect to the horizontal plane. 
     The third body  762   c  may be inclined outward from the upper side to the lower side. For example, the third body  762   c  may include an inner end  762   c   2  and an outer end  792   c   1  based on the radial direction, and the outer end  792   c   1  is located lower than the inner end  762   c   2 . Therefore, the inner end  762   c   2  may be referred to as an upper end and the outer end  792   c   1  may be referred to as a lower end. 
     As an example, referring to  FIG. 13 , the third body  762   c  may extend by an angle C section based on the center O of the frame body  761 . The angle C is smaller than the angle B. 
     The radius of the outer end  762   c   1  (or lower end) of the third body  762   c  may be substantially equal to the radius R 1  of the upper end  762   a   1  of the first body  762   a.    
     The outer end  762   c   1  of the third body  762   c  may be located lower than the outer end of the second body  762   b . The inner end  762   c   2  (or upper end) of the third body  762   c  may be located lower than the outer end  762   b   11  of the first portion  762   b   1  of the second body  762   b . The inner end  762   c   2  of the third body  762   c  may be located above the outer end  762   b   21  of the second portion  762   b   2  of the second body  762   b . That is, the inner end  762   c   2  of the third body  762   c  may be located above one point of the second body  762   b  and lower than another point. 
     The frame body  761  may further include a first contact body  762   c   3  inclined downward toward the center from the inner end  762   c   2  of the third body  762   c.    
     The first contact body  762   c   3  may be in contact with the air guide  170 . 
     The frame body  761  may further include a fourth body  762   d  extending from the third body  762   c.    
     Referring to  FIG. 18 , at a point of the fourth body  762   d , the fourth body  762   d  may be inclined at a fourth angle  84  with respect to the horizontal plane. The fourth angle θ 4  is greater than the third angle θ 3 . 
     The fourth body  762   d  may be inclined outward from the upper side to the lower side. For example, the fourth body  762   d  may include an inner end  762   d   2  and an outer end  792   d   1 , with the outer end  792   d   1  being located lower than the inner end  762   d   2 . 
     The fourth body  762   d  may extend by an angle D section based on the center O of the frame body  761 . The angle D is smaller than the angle C. 
     Referring to  FIG. 13 , for example, a radius R 2  of the outer end  762   d   1  of the fourth body  762   d  is smaller than a radius R 1  of the upper end  762   a   1  of the first body  762   a . The radius R 1  of the outer end  762   d   1  of the fourth body  762   d  is smaller than a radius of the outer end  762   c   1  of the third body  762   c.    
     The radius R 2  of the outer end  762   d   1  of the fourth body  762   d  may be reduced in a direction away from the third body  762   c.    
     The frame body  761  may further include a second contact body  762   d   3  inclined in a downward direction toward the center at the inner end  762   c   2  of the fourth body  762   d . The second contact body  762   d   3  may be in contact with the air guide  170 . 
     The operation of the frame body  761  according to the shape of the frame body  761  as described above will be described. 
     At the standby position of the movable part  750 , the first body  762   a  may face the suction opening  12   a.    
     Since the first body  762   a  is in contact with the air guide  170 , the air introduced through the suction opening  12   a  may flow in the space between the outer surface  762   a   2  and the inner circumferential surface of the first cyclone part  110  may flow. 
     Since the inclination angle of the second body  762   b  is less than the inclination angle of the first body  762   a , the inner surface  762   b   12  of the second body  762   b  may be spaced apart from the air guide  170 . 
     Accordingly, a portion of the air flowing through the space between the outer surface  762   a   2  of the first body  762   a  and the inner circumferential surface of the first cyclone part  110  may flow the space between the air guide  170  and the inner surface  762   b   12  of the second body  762   b . Therefore, the inner surface  762   b   12  of the second body  762   b  serves as a guide surface. 
     Since the inclination angle of the second body  726   b  decreases in a direction away from the first body  762   a , a height of the space between the air guide  170  and the inner surface  762   b   12  of the second body may increase in a direction away from the first body  762   a.    
     The frame body  761  may further include a first extension wall  763  (or outer extension wall) to restrict air from flowing outward in the radial direction of the second body  762   b  in the process in which air flows along the inner surface  762   b   12  of the second body  762   b.    
     The first extension wall  763  may extend upward from an outer end of the second body  762   b . Accordingly, air flowing along the inner surface  762   b   12  of the second body  762   b  may be restricted to flow outward in the radial direction of the second body  762   b  by the first extension wall  763 . The first extension wall  763  may define an air flow path P to be described later. That is, the first extension wall  763  may act as an outer wall of the air flow path P. The first extension wall  763  may guide air in the air flow path P to spirally flow. 
     The frame body  761  may further include a second extension wall  764  (or inner extension wall). The second extension wall  764  may extend in a circumferential direction about the axis of the cyclone flow, and the first extension wall  763  may be spaced outward from the second extension wall  764  in the radial direction. 
     The second extension wall  764  may extend upward from an inner end of the second body  762   b . The second body  762   b  may connect the first extension wall  763  and the second extension wall  764 . The second extension wall  764  may act as an inner wall of the air flow path P. 
     A height of the second extension wall  764  in the first portion  762   b   1  may be lower than a height of the first extension wall  763 . 
     The third body  762   c  functions to guide the air flowing along the inner surface  762   b   12  of the second body  762   b  to fall downward. The fourth body  762   d  serves to guide air that has not fallen downward from the third body  762   c  to finally fall downward. 
       FIG. 19  is a perspective view of an air guide according to an embodiment of the present disclosure.  FIG. 20  is a side view of the air guide of  FIG. 19 . 
     Referring to  FIGS. 19 and 20 , the air guide  170  may include a first guide wall  171 . The air guide  170  may be fixed in position in the main body  2 . 
     An inner circumferential surface of the first guide wall  171  may form a flow path guiding air discharged from the second cyclone part  140 . 
     The first guide wall  171  may be formed in a ring-like shape, for example and a diameter thereof may increase from the lower side to the upper side. Therefore, the air discharged from the second cyclone part  140  may rise smoothly. 
     The first guide wall  171  may include a first seating portion  171   a  allowing a portion of the frame body  761  to be seated or accommodated thereon. The first seating portion  171   a  may be formed as an outer circumferential surface of the first guide wall  171  is recessed in a direction toward the center. The first body  762   a  of the frame body  761  may be seated or accommodated on the first seating portion  171   a.    
     The first guide wall  171  may further include a second seating portion  171   b . The second seating portion  171   b  may be formed as the outer circumferential surface of the guide wall  171  is recessed in a direction toward the center. The first contact body  762   c   3  and the second contact body  762   d   3  of the frame body  761  may be seated and brought into contact with the second seating portion  171   b.    
     A step surface  172  is formed on the first guide wall  171  due to the second seating portion  171   b . The second extension wall  764  may be in contact with the step surface  172 . 
     The inclination angle of the first guide wall  171  with respect to the horizontal plane may be equal to the first angle θ 1  of the first body  762   a , so that the first guide wall  171  and the first body  762   a  may be in contact with each other. 
     In addition, the inclination angles of the first contact body  762   c   3  and the second contact body  762   d   3  with respect to the horizontal plane may be equal to the inclination angle of the first guide wall  171 . Therefore, the first body  762   a  may be in contact with the first seating portion  171   a.    
     In addition, the first contact body  762   c   3  and the second contact body  762   d   3  may be in contact with the second seating portion  171   b.    
     The air guide  170  may further include a second guide wall  173  extending from a lower side of the first guide wall  171 . The second guide wall  173  may be formed in a cylindrical shape or may be formed in a truncated cone shape with a diameter decreasing downward. 
     The air guide  170  may further include a coupling body  174  extending to a lower side of the second guide wall  173 . The second cyclone part  140  may be coupled to the coupling body  174 . 
     A coupling projection  175  may be formed on the outer circumferential surface of the coupling body  174 . The coupling projection  175  may be accommodated in a projection recess (not shown) of the second cyclone part  140 . 
     The air guide  170  may further include a fastening boss  178  (e.g., fastener) extending upward from the inner circumferential surface of the first guide wall  171 . The air guide  170  may be fastened with a component in the body  2  by the fastening boss  178 . 
       FIG. 21  is a view showing an arrangement relation of a movable part and an air guide at a standby position of the movable part.  FIG. 22  is a perspective view of the air guide and the movable part of  FIG. 21 , viewed in a direction “C”.  FIG. 23  is a perspective view of the air guide and the movable part of  FIG. 21 , viewed in a direction “D”.  FIG. 24  is a view showing a contact area CA in contact with the air guide in the frame body. 
     Referring to  FIG. 21 , at the standby position of the movable part  750 , the first body  762   a  may be in contact with the first guide wall  171 . 
     Referring to  FIGS. 22 and 23 , at the standby position of the movable part  750 , the second body  762   b  may be spaced apart from the first guide wall  171 . Accordingly, an air flow path P is formed between the second body  762   b  and the first guide wall  171 . 
     As described above, since the inclination angle of the second body  762   b  with respect to the horizontal plane is reduced in a direction away from the first body  762   a , a height of the air flow path P may be gradually increased. 
     The height of the upper end  763   a  of the first extension wall  763  may be lower in a direction away from the first body  762   a  than towards the first body  762   a . Accordingly, a distance between the upper end  763   a  of the first extension wall  763  and the first guide wall  171  may be gradually increased. 
     The contact area CA in contact with the air guide  170  in the frame  760  is illustrated in  FIG. 24 , and an area other than the contact area CA may form an air flow path in relation to the air guide  170 . 
       FIG. 25  is a view showing a state of air and dust flowing in a state where the movable part moves to the dust compression position in  FIG. 5 .  FIG. 26  is a cross-sectional view taken along lines  26 - 26  of  FIG. 5 .  FIG. 27  is a cross-sectional view taken along line  27 - 27  of  FIG. 5 .  FIG. 28  is a cross-sectional view taken along line  28 - 28  of  FIG. 27 . 
     Referring to  FIGS. 25 to 28 , the suction part  5  includes a flow guide  52  for guiding a flow of air and dust, and the frame guide  765  may extend in the same direction as the extending direction of the flow guide  52  or in a direction parallel thereto. 
     For example, an extending line A 4  extending in a tangential direction of the first housing  10  may be parallel to an extending line A 3  of the frame guide  765 . 
     Therefore, the air introduced into the first cyclone part  110  through the suction opening  12   a  may change in a flow direction by the frame guide  765  and flow along the inner circumferential surface  110   a.    
     At the standby position, the second body  762   b  may be spaced apart from the first guide wall  171  and the upper end  763   a  of the first extension wall  763  may be spaced apart from the first guide wall  171 , a portion of the air flowing along the inner circumferential surface  110   a  of the first cyclone part  110  may flow to the air flow path P. 
     That is, while a portion of the air introduced through the suction opening  12   a  flows along the air flow path P and another portion thereof may spirally flow along the inner circumferential surface  110   a  of the first cyclone part  110 , the air may be separated from dust. 
     In this disclosure, the air flow path P above the frame body  761  may be referred to as an upper flow path and a flow path located below the frame body  761  may be referred to as a lower flow path. 
     In addition, a space between the frame body  761  and the inner circumferential surface of the housing (e.g., the inner circumferential surface  110   a  of the first cyclone part  110 ) may be referred to as a communication flow path connecting the upper flow path and the lower flow path. Air and dust on the upper flow path may move to the lower flow path through the communication flow path. 
     The first body  761   a  may be disposed to face the suction opening  12   a . Therefore, it is possible to prevent air and dust suctioned through the suction opening  12   a  from directly flowing into the air flow path P. 
     The air introduced into the air flow path P may flow along the second body  762   b . Air flowing along the second body  762   b  may be prevented from flowing in the radial direction of the second body  762   b  by the first guide rib  763 . 
     Since the second extension wall  764  may be in contact with the step surface  172  of the air guide  170 , air is prevented from flowing between the second body  762   b  and the second extension wall  172 . 
     Referring to  FIG. 27 , at the standby position of the movable part  750 , the frame body  761  may be spaced apart from the inner circumferential surface  110   a  of the first cyclone part  110 , for example, of the inner surface of the housings  10  and  12 . 
     Therefore, in the process in which the movable part  750  moves in an up and down direction, the movable part  750  may be prevented from rubbing with the inner surfaces of the housings  10  and  12  and air or dust may fall downward through a space between the movable part  750  and the inner surfaces of the housings  10  and  12 . 
     The movable part  750  may be operated by operating the operating part  710  by the user, and thus the user may operate the operating part  710  while the cleaner  1  is operating (suction motor  220  is operating). 
     Referring to  FIG. 25 , during the operation of the cleaner  1 , the movable part  750  may move in a downward direction by the operation of the operating part  710 . 
     A case where the movable part  750  has moved to a position lower than the lower end of the suction opening  12   a  will be described. 
     Since the movable part  750  is spaced apart from the inner circumferential surface  110   a  of the first cyclone part  110  at a position where the movable part  750  has moved in a downward direction, air and dust suctioned through the suction opening  12   a  may move more smoothly downward through a space between the movable part  750  and the inner circumferential surface  110   a  of the first cyclone part  110 . 
     At the position where the movable part  750  has moved downward, dust D may accumulate in the air flow path P formed by the movable part  750 . 
     The movable part  750  may rise in a state where dust D accumulates in the air flow path P of the movable part  750 . When the movable part  750  rises in the state where dust D accumulates in the air flow path P of the movable part  750 , the movable part  750  may not be located at a regular position, and thus the movable part  750  may act as a flow resistance of air flowing through the suction opening  12   a.    
     For example, if large amount of dust D is located in the air flow path P of the movable part  750  and the state where the dust D is not removed from the air flow path P is maintained, the dust may come into contact with the first guide wall  171 , and in this case, the first body  762   a  may be spaced apart from the first guide wall  171 . 
     Here, air suctioned through the suction opening  12   a  may flow between the first body  762   a  and the first guide wall  171 . 
     If the air suctioned through the suction opening  12   a  flows between the first body  762   a  and the first guide wall  171 , air presses the first body  762   a  in a downward direction. 
     Here, even if the user does not operate the operating part  710 , the movable part  750  may move in a downward direction, and thus, dust separation performance may be deteriorated by air flow resistance. 
     In addition, when the first body  762   a  is not in contact with the first guide wall  171 , the movable part  750  is located in an inclined state without maintaining level overall, and thus a downward movement of the movable part  750  is not smooth when the user operates the operating part  710 . 
     However, according to the present disclosure, even if the movable part  750  rises in a state where the dust D accumulates in the air flow path P of the movable part  750 , a portion of air suctioned through the suction opening  12   a  may flow through the air flow path P. 
     When air flows through the air flow path P, the dust D may be moved in the air flow path P by air. 
     In the present embodiment, since the vertical width of the air flow path P gradually increases, the dust D in the air flow path P may be more easily moved together with the air. 
     In addition, referring to  FIGS. 27 and 28 , the dust D flowing along the second body  762   b  may fall downward along the third body  762   c  due to the increase in the inclination angle of the third body  762   c . Even if the dust D does not fall downward along the third body  762   c , the dust may fall downward on the fourth body  762   d  side. 
     In the case of this embodiment, since the radius at the outer end  762   d   1  of the fourth body  762   d  is the minimum at the frame body  761 , a gap between the fourth body  762   d  and the inner circumferential surface  110   a  of the first cyclone part  110  is maximized. 
     In addition, since the inclination angle of the fourth body  762   d  is greater than the inclination angle of the third body  762   c , dust may more easily fall downward along the fourth body  762   d.    
     Therefore, according to the present embodiment, in the cleaning process, even if the movable part rises with dust accumulating on the upper part of the movable part, air flowing along the air flow path of the movable part may move the dust and the moved dust may fall downward, and thus the movable part may be stably located at the regular position. 
     In the above embodiment, it is described that the frame body  761  includes the first body to the fourth body  762   a ,  762   b ,  762   c , and  762   d , but alternatively, the frame body  761  may include the first body to the third body  762   a ,  762   b , and  762   c.    
     In this case, the radius of the third body  762   c  may be less than the radius of the first body  762   a  and the dust D on the air flow path P may fall downward through the space between the third body  762   c  and the inner circumferential surface  110   a  of the first cyclone part  110 . 
     In the present disclosure, the second body  762   b  forming the air flow path P in the frame body  761  may be referred to as a flow path body. The flow path body may include a first portion inclined by a first angle with respect to the horizontal plane and a second portion extending from the first portion and inclined by a second angle smaller than the first angle with respect to the horizontal plane. 
     Further, in the present disclosure, the third body  762   c  may be referred to as a third portion and the first body  762   a  may be referred to as a fourth portion to correspond to the first portion and the second portion of the second body  762   b.    
     The third body  762   c  or the third body  762   c  and the fourth body  762   d  guides the dust in the air flow path P to fall downward, and thus the third body  762   c  or the third body  762   c  and the fourth body  762   d  may be referred to as guide bodies. 
     When the frame body includes only the third body  762   c , a width of at least a portion of the third body may be reduced in the circumferential direction. In this case, for example, a distance between a point of the third body  762   c  and the inner circumferential surface  110   a  of the first cyclone part  110  is greater than a distance between the second body  762   b  and the inner circumferential surface  110   a  of the first cyclone part  110 . 
     It will be apparent to those skilled in the art that various modifications and variations may be made in the present disclosure without departing from the spirit or scope of the disclosures. Thus, it is intended that the present disclosure covers the modifications and variations of this disclosure provided they come within the scope of the appended claims and their equivalents.
