The related art document discloses a compression mechanism including a dust compression part for 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.

In addition, since 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.

At least a portion of the dust compression part is located higher than the opening at the compression standby position.

Meanwhile, when the dust compression part, which has been lowered, rises, if the dust compression part does not accurately move to a standby position, the dust compression part may act as a flow resistance of air and dust flowing through the opening to degrade dust separation performance.

In addition, even if the dust compression part is in contact with the inner circumferential surface of the dust bin, there is a possibility that dust may accumulate 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, resulting in that the dust compression part cannot accurately move to the compression standby position.

<CIT> discloses a vacuum cleaner having a moveable dirt compactor which is moveable between a stowed position and a dirt compacting position.

The present disclosure provides a cleaner in which a compression mechanism, which has moved for compression, can accurately move back to a compression standby position.

The present disclosure provides a cleaner in which a compression mechanism can accurately move to a compression standby position by enabling relative rotation of transfer parts for transferring an operation force of an operating part disposed to be eccentric from the center of a movable part to the movable part.

In addition, according to the present invention, since the transfer parts for transmitting the operation force of the operating part, disposed a position eccentric from the center of the movable part, to the movable part relatively rotate, the movable part may accurately move back to the compression standby position even if the influence of the assembly error exists.

In addition, according to the present invention, in a state where the compression mechanism is accurately located at the compression standby position, the compression mechanism may not act as a flow resistor of air and guide air and dust flowing through the suction opening.

<FIG> is a perspective view of a cleaner according to an embodiment of the present disclosure, <FIG> is a perspective view showing a state where a handle part is separated from a cleaner according to an embodiment of the present disclosure, and <FIG> is a view showing a state where guide frame is separated from <FIG>, <FIG> is an exploded perspective view of a cleaner according to an embodiment of the present disclosure, and <FIG> is a cross-sectional view taken along line <NUM>-<NUM> of <FIG>.

Referring to <FIG>, the cleaner <NUM> according to an embodiment of the present disclosure may include a main body <NUM>. The cleaner <NUM> may further include a suction part <NUM> (or suction inlet) through which air containing dust is suctioned. The suction part <NUM> may guide the air containing dust to the main body <NUM>.

The cleaner <NUM> may further include a handle part <NUM> coupled to the main body <NUM>. The handle part <NUM> may be located on the opposite side of the suction part <NUM> in the main body <NUM>, for example. However, the positions of the suction part <NUM> and the handle part <NUM> are not limited thereto. An extending pipe may be connected to the suction part <NUM>. A suction nozzle may be connected to the extending pipe.

The main body <NUM> may separate the dust suctioned into the inside thereof through the suction part <NUM> and store the separated dust.

In one example, the main body <NUM> may include a dust separator. The dust separator may include a first cyclone part <NUM> capable of separating dust by a cyclone flow. The first cyclone part <NUM> may communicate with the suction part <NUM>.

The air and dust suctioned through the suction part <NUM> spirally flows along an inner circumferential surface of the first cyclone part <NUM>.

The dust separator may further include a second cyclone part <NUM> for separating dust from the air discharged from the first cyclone part <NUM> again.

The second cyclone part <NUM> may include a plurality of cyclone bodies <NUM> arranged in parallel. The air discharged from the first cyclone part <NUM> may be divided and flow into the plurality of cyclone bodies <NUM>, and then pass therethrough.

As another example, it is also possible that the dust separator has a single cyclone part.

The main body <NUM> may be formed in a cylindrical shape, for example, and an outer shape thereof may be formed by a plurality of housings.

In one example, the main body <NUM> may include a first housing <NUM> having a substantially cylindrical shape and a second housing <NUM> coupled to an upper side of the first housing <NUM> and having a substantially cylindrical shape.

An upper portion of the first housing <NUM> defines the first cyclone part <NUM>, and a lower portion of the first housing <NUM> may define a dust bin <NUM> storing dust separated from the first cyclone part <NUM>. Alternatively, a lower side of the second housing <NUM> may define the first cyclone part <NUM>.

A lower side of the first housing <NUM> (i.e., a lower side of the dust bin <NUM>) may be opened and closed by a housing cover <NUM> that rotates by a hinge.

In order to seal a boundary between the first housing <NUM> and the second housing <NUM> in a state where the first housing <NUM> and the second housing <NUM> are coupled, the cleaner <NUM> may further include a sealing member <NUM> and a support body <NUM> supporting the sealing member <NUM>.

Upper and lower sides of each of the first housing <NUM> and the second housing <NUM> are open. That is, each of the housings <NUM> and <NUM> may include an upper opening and a lower opening.

The support body <NUM> may be formed in a cylindrical shape. Here, an outer diameter of the support body <NUM> may be equal to or smaller than an inner diameter of the first housing <NUM> so that the support body <NUM> may be inserted into the first housing <NUM> through the upper opening of the first housing <NUM>.

The outer diameter of the support body <NUM> may be equal to or smaller than an inner diameter of the second housing <NUM> so that the support body <NUM> may be inserted into the second housing <NUM> through the lower opening of the second housing <NUM>.

The support body <NUM> may include a communication opening <NUM> through which air passes. The communication opening <NUM> may communicate with the suction part <NUM>.

The sealing member <NUM> may be coupled to the support body <NUM> to surround an outer circumferential surface of the support body <NUM>. For example, the sealing member <NUM> may be integrally formed with the support body <NUM> by insert injection molding. Alternatively, the sealing member <NUM> may be coupled to the outer circumferential surface of the support body <NUM> by an adhesive.

The main body <NUM> may include a suction opening 12a through which air guided through the suction part <NUM> flows.

One of the first housing <NUM> and the second housing <NUM> may include the suction opening 12a, or the first housing <NUM> may form a part of the suction opening 12a and the second housing <NUM> may form another part of the suction opening 12a.

Hereinafter, a case where the second housing <NUM> includes the suction opening 12a will be described.

When the second housing <NUM> is coupled to the first housing <NUM>, the suction opening 12a of the second housing <NUM> and the communication opening <NUM> of the support body <NUM> are aligned.

The suction opening 12a is aligned with the suction part <NUM>. Therefore, dust and air may be introduced into the first cyclone part <NUM> through the inside of the suction part <NUM>, the suction opening 12a, and the communication opening <NUM>.

In this embodiment, the support body <NUM> may be omitted. In this case, an upper end of the first housing <NUM> may be in direct contact with a lower end of the second housing <NUM>. In addition, dust and air may flow into the first cyclone part <NUM> through the suction opening 12a after passing through the inside of the suction part <NUM>.

In the present disclosure, a configuration for guiding air from the suction part <NUM> to the first cyclone part <NUM> may be referred to as a suction passage of the main body <NUM>.

To sum up, the suction passage may include only the suction opening 12a or may include the suction opening 12a and the communication opening <NUM>.

The main body <NUM> may further include a filter part <NUM> disposed to surround the second cyclone part <NUM>.

The filter part <NUM> is formed in a cylindrical shape, for example, and guides air separated from dust in the first cyclone part <NUM> to the second cyclone part <NUM>. The filter part <NUM> filters dust in the process in which air passes therethrough.

The filter part <NUM> may be arranged to surround an axis A1 of a cyclone flow of the first cyclone part <NUM>.

To this end, the filter part <NUM> may include a mesh portion <NUM> having a plurality of holes. The mesh portion <NUM> may be formed of a metal but is not limited thereto. Since the mesh portion <NUM> filters air, dust may accumulate on the mesh portion <NUM>, and thus the mesh portion <NUM> needs to be cleaned.

In the present disclosure, the cleaner <NUM> may further include a compression mechanism <NUM> capable of compressing dust stored in the first dust storage <NUM>.

Since capacity of the first dust storage <NUM> is limited, the amount of dust stored in the first dust storage <NUM> may increase during repeated cleaning, and thus a period time of and a number of times of using the cleaner continuously without emptying the first dust storage <NUM> may be limited.

If the amount of dust stored in the first dust storage <NUM> increases, the user may rotate the housing cover <NUM> to open the first dust storage <NUM> and then remove dust out of the first dust storage <NUM>.

In this embodiment, when dust stored in the first dust storage <NUM> is compressed using the compression mechanism <NUM>, density of the dust stored in the first dust storage <NUM> increases, and thus a volume thereof decreases.

Therefore, according to the present embodiment, the number of times for emptying the dust bin <NUM> is reduced, and accordingly, an available time for using the cleaner before emptying the dust bin advantageously increases.

The compression mechanism <NUM> may also clean the mesh portion <NUM> during a movement process.

The compression mechanism <NUM> may include a movable part <NUM> (or compression part) movable in the main body <NUM>, an operating part <NUM> (or manipulating part) operated by the user to move the movable part <NUM>, and transfer parts <NUM> and <NUM> transferring an operation force of the operating part <NUM> to the movable part <NUM>.

The movable part <NUM> may have a ring shape and interference with a structure provided in the first dust storage <NUM> may be prevented. The operating part <NUM> may have a structure that the user may press.

For example, the operating part <NUM> may be disposed outside the main body <NUM>. For example, the operating part <NUM> may be located outside the first housing <NUM> and the second housing <NUM>.

At least a portion of the operating part <NUM> may be located higher than the first housing <NUM>. Also, at least a portion of the operating part <NUM> may be located higher than the movable part <NUM>.

The operating part <NUM> may include a pressing part <NUM>. The pressing part <NUM> may be located higher than the first housing <NUM> and the movable part <NUM>.

The operating part <NUM> may include an operating part body <NUM>. The operating part body <NUM> may have a vertical length longer than a horizontal width. The pressing part <NUM> may protrude from an upper portion of the operating part body <NUM>.

The pressing part <NUM> may protrude in the horizontal direction from the operating part body <NUM> in a state where the operating part body <NUM> is disposed in a vertical direction.

In one example, the pressing part <NUM> may be located closer to an upper end than a lower end of the operating part body <NUM>. The pressing part <NUM> may protrude from a position spaced apart downward from the upper end of the operating part body <NUM>.

The pressing part <NUM> may include a first portion 714a protruding from the operating part body <NUM> and a second portion 714b additionally protruding from the first pressing part 714a.

The second portion 714b may protrude from a position spaced apart by a predetermined distance downward from an upper end 714c of the first portion 714a.

The user may move the operating part <NUM> downward by pressing an upper surface 714d of the second portion 714b. Therefore, an upper surface 714d of the second portion 714b serves as a pressing surface.

The operating part <NUM> may further include a coupling projection (See <NUM> of <FIG>) located on the opposite side of the pressing part <NUM> in the operating part body <NUM>.

The handle part <NUM> may include a handle body <NUM> for the user to grip, and a battery housing <NUM> disposed below the handle body <NUM> and accommodating a battery <NUM>.

The handle body <NUM> and the battery housing <NUM> may be disposed in an up-down direction, and the handle body <NUM> may be located above the battery housing <NUM>.

The handle part <NUM> may guide movement of the operating part <NUM>, while covering a portion of the operating part <NUM>.

In one example, the handle part <NUM> may further include an operating part cover <NUM>. The operating part cover <NUM> may be located on the side of the handle body <NUM> and the battery housing <NUM>.

The operating part cover <NUM> may be formed integrally with the handle body <NUM> and the battery housing <NUM> or may be formed separately.

If the operating part cover <NUM> is formed separately from the handle body <NUM> and the battery housing <NUM>, the operating part cover <NUM> may be coupled to the main body <NUM>.

In a state where the user grips the handle body <NUM> by a right hand, the operating part <NUM> may be located on the left of the handle body <NUM>. Of course, in a state where the user grips the handle body <NUM> by a left hand, the operating part <NUM> may be located on the right of the handle body <NUM>. The user may easily operate the operating part <NUM> by a hand that does not grip the handle body <NUM>.

The operating part <NUM> may move in a direction parallel to the axis A1 of the cyclone flow of the first cyclone part <NUM>.

For example, the axis A1 of the cyclone flow of the first cyclone part <NUM> may extend in the up-down direction in a state where the dust bin <NUM> is placed on the floor. Therefore, the operating part <NUM> may also be moved in the up-down direction in a state where the dust bin <NUM> is placed on the floor.

A slot <NUM> may be provided on the operating part cover <NUM> for movement of the operating part <NUM>. The pressing part <NUM> of the operating part <NUM> may penetrate the slot <NUM>.

A vertical length of the operating part body <NUM> may be longer than a vertical length of the slot <NUM>. A horizontal width of the operating part body <NUM> may be longer than a horizontal width of the slot <NUM>.

The horizontal width of the pressing part <NUM> may be equal to or smaller than the horizontal width of the slot <NUM>. The vertical length of the pressing part <NUM> may be smaller than the vertical length of the slot <NUM>. A protruding length of the pressing part <NUM> may be larger than a front-rear width of the operating part cover <NUM>.

Therefore, the pressing part <NUM> may penetrate the slot <NUM> and may protrude outside the operating part cover <NUM> through the slot <NUM>.

The horizontal width of the operating part body <NUM> may be smaller than the horizontal width of the operating part cover <NUM>. The vertical length of the operating part body <NUM> may be smaller than the horizontal width of the operating part cover <NUM>.

A front-rear width of the operating part body <NUM> may be smaller than a front-rear width of the operating part cover <NUM>. The operating part cover <NUM> may form a space for the operating part body <NUM> to be located therein. The operating part body <NUM> may move in the up-down direction in a state where the operating part body <NUM> is located in the operating part cover <NUM>.

In the operating part cover <NUM>, the operating part body <NUM> may move between the first position and the second position.

The first position is a position when the operating part body <NUM> has moved to the top, and the second position is a position when the operating part body <NUM> has moved to the bottom.

In a state where no external force is applied to the operating part <NUM>, the operating part body <NUM> may be located at the first position. The operating part body <NUM> may cover the slot <NUM> in a state where the operating part body <NUM> is located at the first position.

In one example, in a state where the operating part body <NUM> is located at the first position, the operating part body <NUM> may cover the entirety of the slot <NUM> inside the operating part cover <NUM>. Accordingly, in a state where the operating part body <NUM> is located at the first position, the operating part body <NUM> may be exposed to the outside of the slot <NUM> and a space inside the operating part cover <NUM> may be prevented from being exposed.

The slot <NUM> may also extend in a direction parallel to the extending direction of the axis A1 of the cyclone flow of the first cyclone part <NUM>.

In this embodiment, since the extending direction of the axis A1 of the cyclone flow is the up-down direction, for example, in the drawing, the "up-down direction" described below may be understood as the extending direction of the axis A1 of the cyclone flow.

Since the movable part <NUM> is located in the main body <NUM>, the operating part <NUM> is located outside the main body <NUM>, one portion of the transfer parts <NUM> and <NUM> may be located outside the main body <NUM> and the other portion thereof may be located inside the main body <NUM> to connect the movable part <NUM> and the operating part <NUM>.

Portions of the transfer parts <NUM> and <NUM> may penetrate the main body <NUM>. Portions of the transfer parts <NUM> and <NUM> located outside the main body <NUM> may be covered by the handle part <NUM>.

The transfer parts <NUM> and <NUM> may include a first transfer part <NUM>. The first transfer part <NUM> may be coupled to the operating part <NUM>. For example, the first transfer part <NUM> may include a coupling projection <NUM>. The coupling projection <NUM> may be coupled to a projection coupling part (not shown) formed at the operating part body <NUM>.

The coupling projection <NUM> may be formed to have a vertical length larger than a horizontal width thereof. The coupling projection <NUM> may restrict relative rotation of the operating part <NUM> with respect to the first transfer part <NUM> in a horizontal direction.

The transfer parts <NUM> and <NUM> may further include a second transfer part <NUM> coupled with the movable part <NUM>. A portion of the second transfer part <NUM> may be located inside the main body <NUM> and the other portion thereof may be located outside the main body <NUM>.

The second transfer part <NUM> may be directly connected to the first transfer part <NUM> or may be connected by an additional transfer part.

For example, <FIG> illustrates a case where the second transfer part <NUM> is directly connected to the first transfer part <NUM>. The first transfer part <NUM> may include a coupling part <NUM> to which the second transfer part <NUM> may be coupled.

The second transfer part <NUM> may extend in a direction parallel to the axis A1 of the cyclone flow.

In the case of this embodiment, although not limited, the center of the movable part <NUM> may be located on the axis A1 of the cyclone flow or a vertical line passing through the center of the movable part <NUM> may be parallel to the axis A1 of the cyclone flow.

In this embodiment, the operating part <NUM> is disposed at a position eccentric from the center of the movable part <NUM>. Therefore, eccentricity of the movable part <NUM> should be prevented in the process in which the movable part <NUM> moves up and down by the operation of the operating part <NUM>.

If the movable part <NUM> moves up and down in an eccentric state, the movable part <NUM> may not form a horizontal state and may not move smoothly and the movable part <NUM> may not move accurately to a compression standby position.

When the transfer part for transferring an operation force of the operating part <NUM> to the movable part <NUM> includes one transfer part, a possibility that the movable part <NUM> is eccentric in the process of operating the operating part <NUM> is high.

For example, when the operating part <NUM> is directly connected to the movable part <NUM> or connected by a single transfer part, a path through which the operation force of the operating part <NUM> is transferred to the movable part <NUM> is short.

If the operating part <NUM> is operated in an eccentric state with respect to a vertical line, the effect of eccentricity of the operating part <NUM> may directly act on the movable part <NUM> so there is a high possibility that the movable part <NUM> 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 <NUM>, even if the operating part <NUM> is eccentric with respect to the vertical line in the process of operating the operating part <NUM>, the plurality of transfer parts may reduce the influence of the eccentric to minimize the amount of eccentricity of the movable part <NUM>.

The main body <NUM> may further include a protruding body <NUM> for guiding the second transfer part <NUM>. The protruding body <NUM> is, for example, present in a form protruding from the outside of the first housing <NUM>. The protruding body <NUM> protrudes in a radial direction from the first housing <NUM>.

The protruding body <NUM> may extend in a direction parallel to the extending direction of the axis A1 of the cyclone flow of the first cyclone part <NUM>.

The protruding body <NUM> communicates with an internal space of the first housing <NUM>, and the second transfer part <NUM> may move in the protruding body <NUM>.

The cleaner <NUM> may further include a support mechanism <NUM> elastically supporting the compression mechanism <NUM>.

The support mechanism <NUM> may include an elastic member <NUM> providing an elastic force to the compression mechanism <NUM>. The elastic member <NUM> may provide the elastic force to the operating part <NUM> or the transfer parts <NUM> and <NUM>. Hereinafter, a case where the elastic member <NUM> supports the operating part <NUM> will be described.

The elastic member <NUM> may be disposed spaced apart from the second transfer part <NUM> in the horizontal direction. The elastic member <NUM> may be, for example, a coil spring and may be extended and returned to its original length in the up-down direction.

Here, at the first position of the operating part <NUM> (the position of the operating part <NUM> before the user presses the operating part <NUM>), a length of the elastic member <NUM> may be longer than a length of the second transfer part <NUM>.

When the length of the elastic member <NUM> is longer than the length of the second transfer part <NUM>, the operating part <NUM> may be supported using the elastic member <NUM> having a low modulus of elasticity.

In this case, a required force may be reduced when pressing the operating part <NUM>. In addition, when the operating part <NUM> is returned to its original position by the elastic member <NUM>, noise that may occur as the upper end 714c of the first portion 714a in the pressing part <NUM> collides with a surface forming the slot <NUM> of the operating part cover <NUM> may be reduced.

The support mechanism <NUM> may further include a support bar <NUM> supporting the elastic member <NUM> so that a horizontal movement of the elastic member <NUM> is limited in the vertical movement process of the operating part <NUM>.

The support bar <NUM> may be formed in a cylindrical shape, for example. A vertical length of the support bar <NUM> may be longer than a vertical length of the elastic member <NUM>.

The elastic member <NUM> may be disposed to surround the support bar <NUM>. That is, the support bar <NUM> may be located at an inner region of the coil-shaped elastic member <NUM>. An outer diameter of the support bar <NUM> may be equal to or smaller than an inner diameter of the elastic member <NUM>.

One end of the support bar <NUM> may be fixed to the main body <NUM> or a transfer part cover, which will be described later. The first transfer part <NUM> may be coupled to the other end of the support bar <NUM>.

Here, the support bar <NUM> may be coupled to the first transfer part <NUM> after passing through the coupling projection (See <NUM> in <FIG>). A portion of the coupling projection (See <NUM> in <FIG>) may be coupled to the first transfer part <NUM>.

The upper end of the elastic member <NUM> may contact the lower side of the coupling projection (see <NUM> in <FIG>).

The other end of the support bar <NUM> may be an upper end. The upper end of the support bar <NUM> may be coupled to penetrate the first transfer part <NUM>.

Therefore, when the operating part <NUM> is operated downward, the coupling projection (See <NUM> in <FIG>) may press the elastic member <NUM>.

Of course, the coupling projection (See <NUM> in <FIG>) may be omitted in the operating part <NUM>. In this case, when the operating part <NUM> is operated downward, the first transfer part <NUM> may press the elastic member <NUM>.

The first transfer part <NUM> may move up and down along the support bar <NUM>. Accordingly, the support bar <NUM> may guide a vertical movement of the first transfer part <NUM>. Therefore, the support bar <NUM> may be referred to as a guide bar.

The cleaner <NUM> may further include a transfer part cover <NUM> covering the transfer parts <NUM> and <NUM>.

The transfer part cover <NUM> may be coupled to the main body <NUM> in a state of covering the transfer parts <NUM> and <NUM>. The operating part cover <NUM> may cover at least a portion of the transfer part cover <NUM>. In this embodiment, the transfer part cover <NUM> may be omitted and the operating part cover <NUM> may serve as the transfer part cover <NUM>. The transfer part cover <NUM> may also cover the support mechanism <NUM>.

The transfer part cover <NUM> may also cover the support mechanism <NUM>. The first portion <NUM> of the transfer part cover <NUM> may cover the first transfer part <NUM>, the support bar <NUM>, and the elastic member <NUM> at the side of the protruding body <NUM>. The second portion <NUM> of the transfer part cover <NUM> may be located above the protruding body <NUM> and may cover the second transfer part <NUM>.

The transfer part cover <NUM> may include a slot <NUM> at which the coupling projection <NUM> of the first transfer part <NUM> is located. The slot <NUM> may extend in the up-down direction.

The transfer part cover <NUM> may have a bar coupling part <NUM> to which the support bar <NUM> may be coupled.

Meanwhile, the main body <NUM> may further include a suction motor <NUM> for generating a suction force. The suction force generated by the suction motor <NUM> may act on the suction part <NUM>. The suction motor <NUM> may be located in the second housing <NUM>, for example.

The suction motor <NUM> may be located above the dust bin <NUM> and the battery <NUM> with respect to the extending direction of the axis A1 of the cyclone flow of the first cyclone part <NUM>.

The main body <NUM> may further include an air guide <NUM> guiding air passing through the filter part <NUM> to the suction motor <NUM>.

In one example, the air guide <NUM> may guide air discharged from the second cyclone part <NUM> to the suction motor <NUM>.

The second cyclone part <NUM> may be coupled to a lower side of the air guide <NUM>. The filter part <NUM> may surround the second cyclone part <NUM> in a state of being coupled to the second cyclone part <NUM>.

Therefore, the filter part <NUM> may also be located below the air guide <NUM>. The movable part <NUM> may be disposed at a position surrounding the air guide <NUM> in a standby position.

The movable part <NUM> may include a cleaning part <NUM> for cleaning the filter part <NUM>.

In this embodiment, a position of the movable part <NUM> in a state where the operating part <NUM> is not operated may be referred to as a compression standby position. That is, the position of the movable part <NUM> when the operating part <NUM> is located at the first position may be referred to as the compression standby position. A position of the movable part <NUM> when the operating part <NUM> is located at the second position may be referred to as a dust compression position.

At the compression standby position of the movable part <NUM>, the entirety of the cleaning part <NUM> may be disposed not to overlap the filter part <NUM> in a direction in which air passes through the filter part <NUM>.

For example, at the compression standby position of the movable part <NUM>, the entirety of the cleaning part <NUM> may be located higher than the filter part <NUM>.

Accordingly, at the compression standby position of the movable part <NUM>, the cleaning part <NUM> may be prevented from acting as a flow resistor on the way where air passes through the filter part <NUM>.

A dust guide <NUM> may be provided below the second cyclone part <NUM>. A lower side of the second cyclone part <NUM> may be coupled to an upper side of the dust guide <NUM>. In addition, a lower side of the filter part <NUM> may be seated on the dust guide <NUM>.

The lower side of the dust guide <NUM> may be seated on the housing cover <NUM>. The dust guide <NUM> is spaced apart from the inner circumferential surface of the first housing <NUM> and divides an internal space of the first housing into a first dust storage <NUM> storing dust separated at the first cyclone part <NUM> and a second dust storage <NUM> storing dust separated at the second cyclone part <NUM>.

The inner circumferential surface of the first housing <NUM> and the outer circumferential surface of the dust guide <NUM> may define the first dust storage <NUM>, and the inner circumferential surface of the dust guide <NUM> may define the second dust storage <NUM>.

Hereinafter, the compression mechanism <NUM> will be described in more detail.

<FIG> and <FIG> are perspective views of a compression mechanism according to an embodiment of the present disclosure, and <FIG> is an exploded perspective view of a movable part according to an embodiment of the present disclosure. <FIG> is a side view of a frame according to an embodiment of the present disclosure. <FIG> is a perspective view of the frame of <FIG>, viewed in an "A" direction.

Referring to <FIG>, the movable part <NUM> may include a frame <NUM>.

The frame <NUM> compresses dust stored in the first dust storage <NUM>. Therefore, the frame <NUM> may have rigidity for preventing deformation during a pressing process, while effectively compressing dust during the process of compressing dust. For example, the frame <NUM> may be made of an injection-molded material or may be formed of a metal.

A maximum diameter of the frame <NUM> may be smaller than a diameter of an inner circumferential surface of the first cyclone part <NUM>. Therefore, the frame <NUM> may be moved up and down in a state of being spaced apart from the inner circumferential surface of the first cyclone part <NUM>.

In the case of the present embodiment, even if the movable part <NUM> moves in an eccentric state during a vertical movement process, frictional contact of the movable part <NUM> with the inner circumferential surface of the first body <NUM> (for example, the first cyclone part <NUM> and/or dust bin <NUM>) may be prevented.

The frame <NUM> may support the cleaning part <NUM>. The cleaning part <NUM> may be formed of an elastically deformable material. For example, the cleaning part <NUM> may be formed of a rubber material.

The cleaning part <NUM> may be formed in a ring shape so that the cleaning part <NUM> may clean the entirety of the circumference of the cylindrical filter part <NUM>. As another example, the cleaning part <NUM> may be formed of silicone or a fiber material.

When the cleaning part <NUM> is formed of an elastically deformable material, damage to the filter part <NUM> when the cleaning part <NUM> is in frictional contact with the filter part <NUM>.

The movable part <NUM> may move from the compression standby position to a dust compression position. The cleaning part <NUM> may wait at a position outside the filter part <NUM> at the compression standby position, and during a dust compression process, the cleaning part may wipe the outer surface of the filter part <NUM>, while moving to the dust compression position.

The cleaning part <NUM> may include an annular cleaning body <NUM>. The cleaning body <NUM> may include a cleaning end 771a. The cleaning end 771a may be in contact with the outer surface of the filter part <NUM> during the cleaning process.

In the present embodiment, since the cleaning part <NUM> is formed of an elastically deformable material, when the cleaning part is lowered and the cleaning end 771a comes into contact with the filter part <NUM>, the cleaning part <NUM> may be elastically deformed outward in a radial direction of the filter part <NUM>, and in the elastically deformed state, the cleaning end 771a may come into contact with the filter part <NUM>.

Therefore, when the cleaning end <NUM> is lowered in a state where the cleaning end 771a is in contact with the circumference of the filter part <NUM>, the cleaning end 771a removes dust adhered to the outer surface of the filter part <NUM>.

In the case of the present embodiment, since the cleaning end 771a is moved in contact with the filter part <NUM>, the cleaning part <NUM> may reduce eccentricity of the movable part <NUM> in the vertically moving process.

In one example, in a state where the movable part <NUM> is inclined with respect to a horizontal direction, a contact force between a portion of the cleaning end 771a and the filter part <NUM> increases, so that the cleaning end 771a is deformed and inclination of the movable part <NUM> may be reduced.

The cleaning body <NUM> may further include a coupling end <NUM> to be coupled to the frame <NUM>. The coupling end <NUM> may be coupled to an inner surface of the frame <NUM>.

For example, the cleaning part <NUM> may be coupled to the frame <NUM> by insert injection molding.

The cleaning body <NUM> may further include a depressed portion <NUM> recessed downward from the upper end. A lower extending portion 761a extending from the frame <NUM> may be located in the depressed portion <NUM>. The lower extending portion 761a located in the depressed portion <NUM> may be aligned with the suction passage.

The frame <NUM> may include a frame body <NUM> supporting the cleaning part <NUM>. At the compression standby position, a portion of the frame body <NUM> may be in contact with the outer surface of the air guide <NUM>. A portion of the frame body <NUM> may surround an outer surface of the air guide <NUM> in a circumferential direction.

In one example, the frame body <NUM> may include a first body 762a surrounding the outer surface of the air guide <NUM>. The first body 762a may also be referred to as a guide cover part.

For example, the first body 762a may be in contact with the air guide <NUM>. The first body 762a may be disposed to face the suction opening 12a in a state of being spaced apart from the suction opening 12a at the compression standby position of the movable part <NUM>.

The first body 762a may be inclined to have a first inclination angle with respect to a horizontal plane. Accordingly, among the dust introduced into the first cyclone part <NUM> through the suction opening 12a, some dust in contact with the first body 762a may flow downward along the first body 762a.

That is, the frame body <NUM> is designed and disposed to minimize acting as a flow resistor to air suctioned through the suction opening 12a, while a downward flow of dust is smooth, at the compression standby position of the movable part <NUM>.

The frame body <NUM> may further include a second body 762c having a height lowered in a direction away from the first body 762a.

An inclination angle of the second body 762c with respect to the horizontal plane may be reduced in a direction away from the first body 762a. Therefore, the second body 762c may be spaced apart from the air guide <NUM>.

The frame body <NUM> may further include a third body 762d extending from the second body 762c. An inclination angle of the third body 762d with respect to the horizontal plane may increase in a direction away from the second body 762d.

The third body 762d may be connected to the first body 762a.

The upper end 762b of the first body 762a is located higher than the upper end 762e of the third body 762d. Therefore, the upper end 762b of the first body 762a is stepped from the upper end 762e of the third body 762d.

The frame body <NUM> may include a fourth body 762f inclined toward the center of the frame <NUM> from the upper end 762e of the third body 762d.

With respect to a vertical line passing through the upper end, the third body 762d is inclined downward to the outside and the fourth body 762f is inclined downward to the inside. An inclination direction of the fourth body 762f may be the same as an inclination direction of the first body 762b. At least a portion of the fourth body 762f may be in contact with the outer circumferential surface of the air guide <NUM>.

In the present embodiment, a portion of the frame body <NUM> in contact with the air guide <NUM> may be referred to as a contact body. For example, the first body 762a and the fourth body 762f may be referred to as contact bodies.

An outer rib <NUM> extending upward may be provided on the outer circumferential surface of the second body 726c. A height of an upper end of at least a portion of the outer rib <NUM> may be lowered toward the third body 762d.

The lower extending portion 761a may extend downward from a lower side of the first body 762a.

The frame <NUM> may further include a lower extension wall <NUM> extending downward from the frame body <NUM>. The lower extension wall <NUM> may be rounded in the circumferential direction of the frame <NUM>.

The lower extension wall <NUM> may be located at a portion where the outer rib <NUM> is formed in the frame body <NUM>, for example.

The frame <NUM> may further include a coupling part <NUM> extending outward from the lower extension wall <NUM>. The coupling part <NUM> may protrude in the horizontal direction from the lower extension wall <NUM>. For example, the coupling part <NUM> may extend in the horizontal direction from the lower end 766a side of the lower extension wall <NUM>. The second transfer part <NUM> may be connected to the coupling part <NUM>.

In this embodiment, as the coupling part <NUM> is located on the lower end 766a side of the lower extension wall <NUM>, the portion to which the operation force transferred from the transfer part first acts on the lower extension wall <NUM> which is a position spaced apart from the frame body <NUM>, and thus eccentricity of the frame body <NUM> may be reduced.

In addition, in the present embodiment, as the coupling part <NUM> is located on the lower end 766a side of the lower extension wall <NUM>, an increase in height of the cleaner <NUM> may be prevented, while a vertical movement stroke of the movable part <NUM> may be increased.

That is, as a distance between the coupling part <NUM> and the pressing part <NUM> of the operating part <NUM> is increased, the vertical movement stroke of the movable part <NUM> may be increased. When the vertical movement stroke of the movable part <NUM> is increased, compression performance of dust stored in the first dust storage <NUM> may be improved.

A buffer part <NUM> may be coupled to the second transfer part <NUM>. The second transfer part <NUM> may be coupled to penetrate the buffer part <NUM>. The buffer part <NUM> may be seated on an upper surface of the coupling part <NUM> in a state where the buffer part <NUM> is coupled to the second transfer part <NUM>.

The second transfer part <NUM> may penetrate an upper wall of the protruding body <NUM>.

The buffer part <NUM> absorbs a shock that occurs when the movable part <NUM> comes into contact with the upper side wall of the protruding body <NUM> in the process of moving from the dust compression position to the compression standby position, and accordingly, the occurrence of noise may be reduced.

The frame <NUM> may further include a frame guide <NUM> extending downward from the frame body <NUM>. For example, the frame guide <NUM> may extend downward from an outer circumferential surface of the first body 762a.

The frame guide <NUM> may include a planar guide surface 765a. The guide surface 765a may guide a spiral flow of air in the process of air flowing through the suction part <NUM>. The guide surface 765a may be substantially parallel to an extending line extending in a tangential direction of the first cyclone part <NUM>.

The lower end 765b of the frame guide <NUM> may be located lower than the contact end 771a of the cleaning part <NUM>. The lower end 765b of the frame guide <NUM> may be located higher than the lower end 766a of the lower extension wall <NUM>.

The frame body <NUM> may include one or more first guide parts 764a and 764b. The first guide parts 764a and 764b serve to guide the movable part <NUM> to be located at a preset position in relation to the air guide <NUM> at the compression standby position.

In the present embodiment, the first guide parts 764a and 764b may be projections or recesses. <FIG> and <FIG> illustrate the first guide parts 764a and 764b as recesses.

The first guide parts 764a and 764b may be recessed downward at some points of the frame body <NUM>.

For example, a plurality of first guide parts 764a and 764b may be disposed to be spaced apart from each other in the circumferential direction of the frame body <NUM>. The plurality of first guide parts 764a and 764b may be located at the same height in the frame body <NUM>.

In consideration of the position of the coupling part <NUM> in the frame <NUM>, some 764a of the plurality of first guide parts 764a and 764b may be located at the opposite side of the coupling part <NUM> in the frame body <NUM>.

For example, some 764a of the plurality of first guide parts 764a and 764b may be provided on the fourth body 762f.

The other 764b of the plurality of first guide parts 764a and 764b may be located between some 764a of the plurality of first guide parts 764a and 764b and the coupling part <NUM> in the frame body <NUM> in the circumferential direction. For example, the other 764b of the plurality of first guide parts 764a and 764b may be provided on the first body 762a.

That is, the plurality of first guide parts 764a and 764b may be formed on a surface of the frame body <NUM> facing the air guide <NUM>.

<FIG> is a side view of the air guide according to an embodiment of the present disclosure. <FIG> is a view showing an arrangement relationship of the movable part and the air guide at the compression standby position of the movable part and <FIG> is a cross-sectional view taken along line <NUM>-<NUM> of <FIG>.

Referring to <FIG>, a position of the air guide <NUM> may be fixed in the housings <NUM> and <NUM>.

The air guide <NUM> may be located in an inner region of the frame <NUM> at the compression standby position of the movable unit <NUM> and support the frame <NUM>.

The air guide <NUM> may include a guide body <NUM>. An inner circumferential surface of the guide body <NUM> may form a flow path guiding air discharged from the second cyclone part <NUM>.

The guide body <NUM> may be provided in the form of a ring, for example, and at least a portion thereof may be reduced in diameter from the upper side to the lower side. That is, the guide body <NUM> may be inclined at a certain angle with respect to a vertical line or the axis A1 of the cyclone flow.

The guide body <NUM> may include a first seating portion 171a allowing a portion of the frame body <NUM> to be seated thereon. The first seating portion 171a may be formed in the manner that an outer circumferential surface of the guide body <NUM> is recessed toward the center. The first body 762a of the frame body <NUM> may be seated on the first seating portion 171a.

The guide body <NUM> may further include a second seating portion 171b. The second seating portion 171b may be formed in the manner that the outer circumferential surface of the guide body <NUM> is recessed toward the center. The first seating portion 171a and the second seating portion 171b are arranged in a circumferential direction of the guide body <NUM>.

At least the fourth body 762f may be seated on the second seating portion 171b in the frame body <NUM>.

The guide body <NUM> may further include an extending body <NUM> disposed to face the contact end 771a of the cleaning part <NUM> at the compression standby position. The extending body <NUM> may be located below the first seating portion 171a and the second seating portion 171b.

The guide body <NUM> may further include a coupling body <NUM> extending to a lower side of the extending body <NUM>. The second cyclone part <NUM> may be coupled to the coupling body <NUM>.

A coupling projection <NUM> may be formed on the outer circumferential surface of the coupling body <NUM>. The coupling projection <NUM> may be accommodated in a projection recess (not shown) of the second cyclone part <NUM>.

The air guide <NUM> may further include a fastening boss <NUM> extending upward from the inner circumferential surface of the guide body <NUM>. The air guide <NUM> may be fastened to one component in the body <NUM> by the fastening boss <NUM>.

Meanwhile, the air guide <NUM> further includes second guide parts 171c and 171d which may be combined with the first guide parts 764a and 764b.

In this embodiment, the second guide parts 171c and 171d are projections or recesses. That is, one of the first guide parts 764a and 764b and the second guide parts 171c and 171d is a projection and the other is a recess in which the projection is accommodated.

Hereinafter, a case where the second guide parts 171c and 171d are projections will be described.

When the movable part <NUM> moves to the compression standby position, the second guide parts 171c and 171d may be inserted into the first guide parts 764a and 764b. That is, the second guide parts 171c and 171d may be coupled to the first guide parts 764a and 764b in a direction parallel to the axis of the cyclone flow.

A plurality of second guide parts 171c and 171d may be provided in the air guide <NUM> to correspond to the plurality of first guide parts 764a and 764b.

The plurality of second guide parts 171c and 171d may also be arranged spaced apart from each other in the circumferential direction at the air guide <NUM>.

In this embodiment, the second guide parts 171c and 171d may protrude from the guide body <NUM>.

Since some <NUM> of the plurality of first guide parts 764a and 764b are provided in the fourth body 762f of the frame body <NUM>, some 171c of the plurality of second guide parts 171c and 171d may be provided on the second seating portion 171b.

Since the other 764b of the plurality of first guide parts 764a and 764b is provided in the first body 762a of the frame body <NUM>, the other 171d of the plurality of second guide parts 171c and 171d may be provided on the first seating portion 171a.

Referring to <FIG> and <FIG>, the frame body <NUM> surrounds the air guide <NUM> at the compression standby position of the movable part <NUM>.

In addition, at the compression standby position of the movable part <NUM>, the first guide parts 764a and 764b and the second guide parts 171c and 171d are coupled.

By coupling the first guide parts 764a and 764b and the second guide parts 171c and 171d, the movable part <NUM> may be located at a preset position under the compression standby position, and the state where the movable part <NUM> is located at the preset position may be maintained.

If the first guide parts 764a and 764b and the second guide parts 171c and 171d do not exist, the position of the movable part <NUM> relative to the fixed air guide <NUM> may change.

If the movable part <NUM> is not located at the preset position with respect to the air guide <NUM>, a portion of the frame body <NUM> in contact with the air guide <NUM> may not be in contact with the air guide <NUM> or a relative position of the frame guide <NUM> with respect to the suction opening 12a may be different.

In this case, air or dust suctioned through the suction opening 12a may flow between the first body 762a of the frame body <NUM> and the air guide <NUM> to increase a gap between the air guide <NUM> and the first body 762a, causing a possibility that the first body 762a acts as a flow resistor to air.

In addition, if the relative position of the frame guide <NUM> with respect to the suction opening 12a changes, the function of the frame guide <NUM> for causing air to spirally flow is not smoothly performed but rather the frame guide <NUM> may act as a flow resistor to air.

However, according to the present disclosure, since the second guide parts 171c and 171d are inserted into the first guide parts 764a and 764b in the process in which the movable part <NUM> moves from the dust compression position to the compression standby position, the movable part <NUM> may be located at the preset position under the compression standby position.

In the case of this embodiment, the second guide parts 171c and 171d protrude from the guide body <NUM> which is an inclined portion and the first guide parts 764a and 764b are recessed at the inclined portion of the frame body <NUM>.

Therefore, in the process of moving the moving part <NUM> from the dust compression position to the compression standby position, the second guide parts 171c and 171d may be smoothly inserted into or seated on the first guide parts 764a and 764b.

As in the present embodiment, in a state where the first guide parts 764a and 764b and the second guide parts 171c and 171d are coupled, the movable part <NUM> based on the center of the movable part <NUM> may be prevented from being rotated horizontally.

<FIG> is a cross-sectional view taken along line <NUM>-<NUM> of <FIG>.

Referring to <FIG> and <FIG>, in the present embodiment, the first transfer part <NUM> and the second transfer part <NUM> may be formed of different materials.

In one example, the second transfer part <NUM> may be formed of a metal material and the first transfer part <NUM> may be formed of a non-metal material.

The second transfer part <NUM> is a component which is directly connected to the frame <NUM> through the protruding body <NUM>. When the second transfer part <NUM> is formed of a metal material, the second transfer part may be prevented from being deformed in the process of moving the transfer part <NUM>.

When the first transfer part <NUM> is formed of a non-metal material, the first transfer part <NUM> may be easily combined with the second transfer part <NUM>.

The second transfer part <NUM> may be formed in a cylindrical shape, for example. The first transfer part <NUM> may be connected to an upper portion of the second transfer part <NUM>.

For example, after the second transfer part <NUM> is manufactured, the first transfer part <NUM> may be manufactured by injection molding together with being combined with the second transfer part <NUM> (e.g., double injection molding).

Part of an upper portion of the second transfer part <NUM> may have a smaller diameter than other portions. The first transfer part <NUM> may be coupled to the portion having a small diameter of the second transfer part <NUM>.

The first transfer part <NUM> may include a first connection portion <NUM> connected to the support bar <NUM>, a second connection portion <NUM> connected to the second transfer part <NUM>, and a connection body <NUM> connecting the first connection portion <NUM> and the second connection portion <NUM>.

The second transfer part <NUM> may have a coupling recess 731a in the circumferential direction. The coupling recess 731a may be continuously formed around the second transfer part <NUM>. That is, the coupling recess 731a may be formed in a ring shape.

The coupling recess 731a may be disposed at a position spaced downward from an upper end of the second transfer part <NUM>.

When the first transfer part <NUM> is injection-molded, the first transfer part <NUM> may include a coupling projection 724a inserted into the coupling recess 731a. For example, the second connection portion <NUM> includes the coupling projection 724a.

Since the coupling projection 724a is located in the coupling recess 731a, the first transfer part <NUM> may be limited from moving in a longitudinal direction of the second transfer part <NUM>.

Meanwhile, since the coupling recess 731a is formed in a ring shape on the second transfer part <NUM>, the coupling projection 724a may also have a ring shape. When the coupling projection 724a has a ring shape, the coupling projection 724a is horizontally rotatable in the coupling recess 731a. Therefore, the first transfer part <NUM> may be rotated relative to the second transfer part <NUM>.

As described above, not only eccentricity of the movable part <NUM> must be prevented but also the movable part <NUM> must be located in the preset position of the compression standby position.

In case where there is an assembly error of the operating part <NUM> and the first transfer part <NUM> or an assembly error of other components as in this embodiment, if the first transfer part <NUM> and the second transfer part <NUM> do not relatively rotate, the second transfer part <NUM> is affected by the assembly error.

Then, since the movable part <NUM> connected to the second transfer part <NUM> is affected by the error, the first guide parts 764a and 764b and the second guide parts 171c and 171d may not be coupled while the movable part <NUM> moves to the compression standby position.

However, as in the present disclosure, if the relative position of the second transfer part <NUM> with respect to the first transfer part <NUM> can be adjusted, the second transfer part <NUM> may be unaffected by the error, and accordingly, the movable part <NUM> may also be unaffected by the assembly error.

Alternatively, the influence of the assembly error may be eliminated by the relative rotation of the first transfer part <NUM> and the second transfer part <NUM> while the movable unit <NUM> moves to the compression standby position.

For example, even if the positions of the first guide parts 764a and 764b and the second guide parts 171c and 171d are not perfectly aligned in an up-down direction in the process in which the movable part <NUM> moves to the compression standby position, the first guide parts 764a and 764b and the second guide parts 171c and 171d may be aligned and coupled to each other by the relative rotation of the second transfer part <NUM> and the first transfer part <NUM>.

According to the proposed embodiment, after the compression mechanism moves for compression by the first guide part and the second guide part, it can accurately move back to the compression standby position.

In addition, according to the present embodiment, since the transfer parts for transmitting the operation force of the operating part disposed a position eccentric from the center of the movable part to the movable part relatively rotate, the movable part may accurately move back to the compression standby position even if the influence of the assembly error exists.
