Description

Cleaner {Clearner}

This specification relates to a vacuum cleaner.

A vacuum cleaner is a device that sucks or wipes dust or foreign matter on a cleaning target area.

Such a vacuum cleaner may be divided into a manual cleaner for cleaning while the user directly moves the cleaner, and an automatic cleaner for cleaning while driving by itself.

In addition, manual cleaners may be classified into canister-type cleaners, upright-type cleaners, handheld cleaners, and stick-type cleaners, depending on the shape of the cleaner.

Prior literature: US Patent Publication US2018/0132685A1

In the prior literature, a compression mechanism including a dust compression unit for compressing dust in a dust container is disclosed.

The cleaner includes a dust container having an opening, a filter for purifying air in the dust container, a shroud surrounding the filter, a dust compressing unit disposed to surround the shroud, and a user to move the dust compressing unit It may include a handle to manipulate and a link connected to the handle.

As the operation force of the handle is transmitted to the dust compression unit through the link and the dust compression unit descends, the dust compression unit compresses the dust in the dust bin.

However, according to the prior literature, at least a part of the dust compression unit is located higher than the opening in the standby position, so that the dust compression unit is accommodated in the dust bin without guiding the flow of air.

Accordingly, there is a disadvantage in that the space inside the dust bin is reduced as much as the thickness of the dust compression part, and as a result, the space for dust separation is reduced.

In addition, the lower surface of the dust compression unit compresses the dust stored in the dust bin. When the dust compression unit is positioned higher than the opening, the dust compression unit moves up and down to compress the dust within a limited vertical length range, thereby compressing dust The performance is reduced.

In addition, since the dust compressing unit moves while in contact with the inner circumferential surface of the dust container, it is possible to clean the inner circumferential surface of the dust container, but there is a possibility that dust will be collected between the dust compressing unit and the inner circumferential surface of the dust container. In this case, the dust compressing unit There is a disadvantage that the vertical movement is not smooth.

The present embodiment provides a cleaner capable of guiding the air and dust introduced through the movable portion through the suction opening.

For example, the main body 2 may include a dust separator. The dust separation unit may include a first cyclone unit 110 capable of separating dust by cyclone flow. The first cyclone unit 110 may communicate with the suction unit 5.

Air and dust sucked through the suction unit 5 spirally flow along the inner circumferential surface of the first cyclone unit 110.

The dust separation unit may further include a second cyclone unit 140 for separating the dust from the air discharged from the first cyclone unit 110 again.

The second cyclone unit 140 may include a plurality of cyclone bodies 142 disposed in parallel. Air may be divided into the plurality of cyclone bodies 142 and passed therethrough.

As another example, it is possible that the dust separation unit has a single cyclone unit.

The body 2 may be formed in a cylindrical shape, for example, and may have an outer shape formed by a plurality of housings.

For example, the main body 2 may include a first housing 10 having a substantially cylindrical shape, and a second housing 12 coupled to the upper side of the first housing 10 and having a substantially cylindrical shape. .

A dust bin in which an upper portion of the first housing 10 defines the first cyclone portion 110, and a lower portion of the first housing 10 stores dust separated from the first cyclone portion 110 (112) can be defined. The dust bin 112 may include a first dust storage unit 120 that stores dust separated from the first cyclone unit 110.

The lower side of the first housing 10 (ie, the lower side of the dust container 112) may be opened and closed by the housing cover 114 rotating by a hinge.

The support body 14 may be formed in a cylindrical shape. At this time, the outer diameter of the support body 14 is the first housing 10 so that the support body 14 can be inserted into the first housing 10 through the upper opening of the first housing 10. It may be formed equal to or smaller than the inner diameter of.

The outer diameter of the support body 14 is the inner diameter of the second housing 12 so that the support body 14 can be inserted into the second housing 12 through the lower opening of the second housing 12. It may be formed equal to or smaller than

The support body 14 may include a communication opening 15 through which air passes.

The sealing member 16 may be coupled to the support body 14 to surround the outer circumferential surface of the support body 14. For example, the sealing member 16 may be integrally formed with the support body 14 by insert injection. Alternatively, the sealing member 16 may be coupled to the outer peripheral surface of the support body 14 by an adhesive.

The main body 2 may include a suction opening (see 12a of FIG. 12) through which air guided through the suction part 5 is introduced.

Either one of the first housing 10 and the second housing 12 includes the suction opening (see 12A in Fig. 12), or the first housing 10 is the suction opening (see 12A in Fig. 12). ), and the second housing 12 may form another part of the suction opening (see 12A of FIG. 12).

When the second housing 12 is coupled with the first housing 10, the suction opening 12a of the second housing 12 and the communication opening 15 of the support body 14 are aligned.

The suction opening 12a is aligned with the suction part 5. Accordingly, dust and air may be introduced into the first cyclone unit 110 through the inside of the suction unit 5, through the suction opening 12a and the communication opening 15.

In this embodiment, the support body 14 may be omitted. In this case, the upper end of the first housing 10 may directly contact the lower end of the second housing 12. In addition, dust and air may be introduced into the first cyclone unit 110 through the suction opening 12a after passing through the interior of the suction unit 5.

In this specification, 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.

In summary, the suction passage may include only the suction opening 12a or may include the suction opening 12a and the communication opening 15.

The body 2 may further include a filter unit 130 disposed to surround the second cyclone unit 140.

The filter unit 130 is formed in a cylindrical shape, for example, and guides the air separated from the dust in the first cyclone unit 110 to the second cyclone unit 140. The filter unit 130 filters dust while air passes.

The filter unit 130 may be disposed to surround the axis A1 of the cyclone flow of the first cyclone unit 110.

To this end, the filter unit 130 may include a mesh portion 132 having a plurality of holes. The mesh portion 132 is not limited, but may be formed of a metal material.

Since the mesh part 132 filters the air, dust may accumulate in the mesh part 132, and the mesh part 132 needs to be cleaned.

In the present invention, the cleaner 1 may further include the compression mechanism 70 capable of compressing dust stored in the first dust storage unit 121.

Since the volume of the first dust storage unit 120 is limited, the amount of dust stored in the first dust storage unit 120 increases during repeated cleaning, and accordingly, the use of the cleaner 1 The time or number may be limited.

If the amount of dust stored in the first dust storage unit 120 increases, the user causes the housing cover 114 to open the first dust storage unit 120 so that the first dust storage unit ( 120) of dust should be emptied.

In this embodiment, when the dust stored in the first dust storage unit 120 is compressed using the compression mechanism 70, the density of the dust stored in the first dust storage unit 120 increases, and accordingly The volume is reduced.

Accordingly, according to the present embodiment, the number of times for emptying the dust bin 112 is reduced, and accordingly, the usable time before emptying the dust is increased.

The compression mechanism 70 may also clean the mesh portion 132 during the moving process.

The compression mechanism 70 includes a movable part 750 that is movable within the main body 2, an operation part 710 operated by a user to move the movable part 750, and an operation force of the operation part 710. It may include a delivery unit (720, 730) for delivery to the movable part (750).

The manipulation unit 710 may be disposed outside the main body 2. For example, the manipulation unit 710 may be located outside the first housing 10 and the second housing 12.

At least a portion of the manipulation unit 710 may be positioned higher than the first housing 10. In addition, at least a portion of the manipulation unit 710 may be positioned higher than the movable unit 750.

The manipulation unit 710 may include a pressing unit 714. The pressing part 714 may be positioned higher than the first housing 10 and the movable part 750.

The manipulation unit 710 may include the manipulation unit body 712. The manipulator body 712 may have a vertical length longer than that of a left and right width. The pressing part 714 may protrude from the upper side of the operation part body 712.

In a state in which the manipulation part body 712 is disposed in a vertical direction, the pressing part 714 may protrude from the manipulation part body 712 in a horizontal direction.

For example, the pressing part 714 may be positioned closer to an upper end than a lower end of the manipulation part body 712.

The pressing part 714 may protrude from a position spaced downward from the upper end of the operation part body 712.

The pressing part 714 may include a first part 714a protruding from the operation part body 712 and a second part 714b additionally protruding from the first pressing part 714a.

The handle body 30 and the battery housing 60 may be disposed in a vertical direction, and the handle body 30 may be positioned above the battery housing 60.

The handle part 3 may guide the movement of the manipulation part 710 while covering a part of the manipulation part 710.

For example, the handle part 3 may further include an operation part cover 62. The operation part cover 62 may be located at the side of the handle body 30 and the battery housing 60.

The operation part cover 62 may be integrally formed with the handle body 30 and the battery housing 60 or may be formed separately.

When the operation part cover 62 is formed separately from the handle body 30 and the battery housing 60, the operation part cover 62 may be coupled to the main body 2.

In a state in which the user grips the handle body 30 with the right hand, the manipulation unit 710 may be located on the left side of the handle body 30. Of course, while the handle body 30 is held by the left hand, the manipulation unit 710 may be positioned on the right side of the handle body 30.

The manipulation unit 710 can be easily operated with a hand that does not hold the handle body 30.

The manipulation unit 710 may move in a direction parallel to the axis A1 of the cyclone flow of the first cyclone unit 110.

For example, the axis A1 of the cyclone flow of the first cyclone unit 110 may extend in the vertical direction while the dust container 112 is placed on the floor.

Accordingly, the manipulation unit 710 may also be moved in the vertical direction while the dust bin 112 is placed on the floor.

A slot 63 may be formed in the operation part cover 62 to move the operation part 710. The pressing part 714 of the manipulation part 710 may pass through the slot 63.

The upper and lower lengths of the manipulator body 712 may be longer than the length of the slot 63. The left and right widths of the manipulator body 712 may be longer than the left and right widths of the slot 63.

The left and right widths of the pressing portion 714 may be equal to or smaller than the left and right widths of the slot 63. The vertical length of the pressing part 714 may be smaller than the vertical length of the slot 63.

The protruding length of the pressing part 714 may be greater than the front and rear width of the manipulation part cover 62.

Accordingly, the pressing part 714 may pass through the slot 63, and may protrude to the outside of the manipulation part cover 62 while passing through the slot 63.

The left and right widths of the manipulation unit body 712 may be smaller than the left and right widths of the manipulation unit cover 62. The upper and lower lengths of the operation part body 712 may be smaller than the left and right widths of the operation part cover 62.

The front and rear widths of the manipulation unit body 712 may be smaller than the front and rear widths of the manipulation unit cover 62. The manipulation part cover 62 may form a space in which the manipulation part body 712 is located. While the manipulation part body 712 is positioned within the manipulation part cover 62, the manipulation part body 712 may move up and down.

The manipulation part body 712 may move between a first position and a second position within the manipulation part cover 62.

The first position is a position when the manipulator body 712 is moved to the uppermost side, and the second position is a position when the manipulator body 712 is moved to the lowest side.

In a state in which no external force is applied to the manipulation unit 710, the manipulation unit body 712 may be positioned at the first position.

When the manipulation part body 712 is positioned at the first position, the manipulation part body 712 may cover the slot 63.

For example, while the manipulation part body 712 is positioned at the first position, the manipulation part body 712 may cover the entire slot 63 from the inside of the manipulation part cover 62. Accordingly, while the manipulation part body 712 is positioned at the first position, the manipulation part body 712 may be exposed to the outside of the slot 63, and the space inside the manipulation part cover 62 is external Exposure can be prevented.

The slot 63 may also extend in a direction parallel to an extension direction of the axis A1 of the cyclone flow of the first cyclone part 110.

In this embodiment, since the extending direction of the axis A1 of the cyclone flow is an example in the drawing, the “up and down direction” described below means that the extending direction of the axis A1 of the cyclone flow is Can be understood as

Since the movable part 750 is located in the main body 2 and the operation part 710 is located outside the main body 2, the transfer unit 720 is connected to the movable part 750 and the operation part 710. A part of 730 may be located outside the body 2, and another part of the body 2 may be located inside the body 2.

Some of the delivery units 720 and 730 may pass through the main body 2. A portion of the delivery units 720 and 730 positioned outside the main body 2 may be covered by the handle part 3.

The delivery units 720 and 730 may include a first delivery unit 720. The first transmission unit 720 may be coupled to the manipulation unit 710. For example, the first transmission part 720 may include a coupling protrusion 722. The coupling protrusion 722 may be coupled to a protrusion coupling portion (not shown) formed on the manipulation unit body 712.

The coupling protrusion 722 may have a vertical length larger than a left and right width. The coupling protrusion 722 may limit relative rotation of the manipulation unit 710 in a horizontal direction with respect to the first transmission unit 720.

The delivery units 720 and 730 may further include a second transmission unit 730 coupled to the movable unit 750.

A part of the second transmission part 730 may be located inside the body 2, and another part may be located outside the body 2.

The second transmission unit 730 may be directly connected to the first transmission unit 720 or may be connected by an additional transmission unit.

3, for example, the second transmission unit 730 is shown to be directly connected to the first transmission unit 720. The first transmission part 720 may include a coupling part 724 to which the second transmission part 730 is coupled.

The second transmission unit 730 may extend in a direction parallel to the axis A1 of the cyclone flow.

In the case of the present embodiment, although not limited, the center of the movable part 750 is located on the axis of the cyclone flow (A1), or a vertical line passing through the center of the movable part 750 is the axis of the cyclone flow (A1). Can be parallel with

In this embodiment, the manipulation unit 710 is disposed at a position eccentric from the center of the movable unit 750.

Accordingly, eccentricity of the movable part 750 must be prevented in the process of moving the movable part 750 up and down by the manipulation of the manipulation part 710.

If the movable part 750 is moved up and down in an eccentric state, the movable part 750 may not be in a horizontal state, so that the movable part 750 may not move smoothly, and the movable part 750 is moved to the standby position. It will not be able to move accurately.

When the transfer unit for transmitting the operating force of the manipulation unit 710 to the movable unit 750 includes one transfer unit, there is a high possibility that the movable unit 750 is eccentric during the operation of the manipulation unit 710.

For example, when the manipulation unit 710 is directly connected to the movable unit 750 or connected by a single transmission unit, a path through which the operating force of the manipulation unit 710 is transmitted to the movable unit 750 is short.

If the operation unit 710 is operated in an eccentric state based on a vertical line, the effect of the eccentricity of the operation unit 710 directly acts on the movable unit 750 so that the movable unit 750 is also eccentric. It is likely to be moved.

However, as in the present invention, when the delivery unit transmits the operation force of the operation unit including a plurality of transmission units to the movable unit 750, the operation unit 710 is based on a vertical line during the operation of the operation unit 710. Even if it is eccentric, the amount of eccentricity of the movable part 750 may be minimized by reducing the influence of the eccentricity of the plurality of transmission parts.

The body 2 may further include a protruding body 180 for guiding the second transmission part 730. For example, the protruding body 180 exists in a protruding form outside the first housing 10.

The protruding body 180 may extend in a direction parallel to an extension direction of the axis A1 of the cyclone flow of the first cyclone part 110.

The protruding body 180 communicates with the inner space of the first housing 10, and the second transmission part 730 may move within the protruding body 180.

The cleaner 1 may further include a support mechanism 780 for elastically supporting the compression mechanism 70.

The support mechanism 780 may include an elastic member 781 for providing an elastic force to the compression mechanism 70.

The elastic member 781 may provide elastic force to the manipulation unit 710 or the delivery units 720 and 730. Hereinafter, it will be described that the elastic member 781 supports the manipulation unit 710 by way of example.

The elastic member 781 may be disposed to be spaced apart from the second transmission part 730 in a horizontal direction.

The elastic member 781 may be, for example, a coil spring, and may be stretched and stretched in a vertical direction.

At this time, in the first position of the manipulation unit 710 (the position of the manipulation unit 710 before the user presses the manipulation unit 710), the length of the elastic member 781 is the length of the second transmission unit 730 It can be formed longer.

When the length of the elastic member 781 is longer than the length of the second transmission unit 730, the elastic member 781 having a low elastic modulus may be used to support the manipulation unit 710.

In this case, when pressing the operation unit 710, a required force may be reduced. In addition, when the operation part 710 is originally returned by the elastic member 781, the upper end 714c of the first part 714a in the pressing part 714 is a slot of the operation part cover 62. Noise generated while colliding with the surface forming the (63) can be reduced.

The support mechanism 780 may further include a support bar 790 for supporting the elastic member 781 so that horizontal movement of the elastic member 781 is restricted during the vertical movement of the manipulation unit 710. I can.

The support bar 790 may be formed in a cylindrical shape, for example. The upper and lower lengths of the support bar 790 may be longer than the upper and lower lengths 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 in an inner region of the coil-shaped elastic member 781. The outer diameter of the support bar 790 may be equal to or smaller than the inner diameter of the elastic member 781.

One end of the support bar 790 may be fixed to the main body 2 or a delivery unit cover to be described later. The first transmission part 720 may be coupled to the other end of the support bar 790.

In this case, the support bar 790 may be coupled to the first transmission unit 720 after passing through the coupling protrusion (see 716 in FIG. 6 ). A part of the coupling protrusion (see 716 of FIG. 6) may be coupled to the first transmission part 720.

An upper end of the elastic member 781 may contact a lower side of the coupling protrusion (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 pass through the first transmission part 720.

The main body 2 may further include an air guide 170 for guiding the air that has passed through the filter unit 130 to the suction motor 220.

For example, the air guide 170 may guide the air discharged from the second cyclone unit 140 to the suction motor 220.

The second cyclone part 140 may be coupled to the lower side of the air guide 170. The filter unit 130 may surround the second cyclone unit 140 in a state coupled to the second cyclone unit 140.

Accordingly, the filter unit 130 may also be located under the air guide 170. The movable part 750 may be disposed in 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 the present embodiment, a position of the movable unit 750 in a state in which the operation unit 710 is not operated (an initial position of the operation unit 710) may be referred to as a standby position (or a first position).

That is, the position of the movable unit 750 when the manipulation unit 710 is positioned at the first position may be referred to as a standby position. The position of the movable unit 750 when the manipulation unit 740 is positioned at the second position may be referred to as a dust compression position (or a second position).

In the standby position of the movable part 750, all of the cleaning part 770 may be disposed in a direction in which air passes through the filter part 130 and not overlapping with the filter part 130.

For example, in the standby position of the movable part 750, all of the cleaning part 770 may be located higher than the filter part 130.

Accordingly, in the standby position of the movable part 750, the cleaning part 770 may be prevented from acting as a flow resistance during the air passing through the filter part 130.

A dust guide 160 may be provided below the second cyclone part 140. The lower side of the second cyclone part 140 may be coupled to the upper side of the dust guide 160. In addition, the lower side of the filter unit 130 may be seated on the dust guide 160.

It is divided into a unit 120 and a second dust storage unit 122 that stores the dust separated by the second cyclone unit 140.

The inner circumferential surface of the first housing 10 and the outer circumferential surface of the dust guide 160 define the first dust storage unit 120, and the inner circumferential surface of the dust guide 160 is the second dust storage unit 122 Can be defined.

Hereinafter, the compression mechanism 70 will be described in more detail.

6 and 7 are perspective views of a compression mechanism according to an embodiment of the present invention, and FIG. 8 is an exploded perspective view of a movable part according to an embodiment of the present invention. 9 is a side view of a frame according to an embodiment of the present invention.

6 to 9, the movable part 750 may include a frame 760.

The frame 760 may be arranged to surround the axis A1 of the cyclone flow. The frame 760 may be formed in a ring shape centered on the axis A1 of the cyclone flow.

The maximum diameter of the frame 760 may be smaller than the diameter of the inner peripheral surface of the first cyclone part 110. Accordingly, the frame 760 may be moved up and down in a state spaced apart from the inner circumferential surface of the first cyclone unit 110.

In the present embodiment, even if the movable part 750 moves to an eccentric state during the vertical movement of the movable part 750, the movable part 750 is disposed on the inner circumferential surface of the first housing 10 (for example, the first cyclone Rubbing with the part 110 and/or the dust bin 112 may be prevented.

In addition, when the frame 760 is spaced apart from the inner circumferential surface of the first cyclone unit 110, it is sucked into the first cyclone unit 110 while the movable unit 750 is moved downward during the cleaning process. The formed air and dust may flow downward through the inner peripheral surface of the first cyclone part 110 and the frame 760.

The frame 760 may support the cleaning unit 770. The cleaning unit 770 may be formed of an elastically deformable material. For example, the cleaning unit 770 may be formed of a rubber material.

The cleaning unit 770 may be formed in a ring shape so that the cleaning unit 770 can clean the entire circumference of the cylindrical filter unit 130. As another example, the cleaning unit 770 may be formed of a silicone or fiber material.

When the cleaning unit 770 is formed of an elastically deformable material, damage to the filter unit 130 may be prevented during a friction between the cleaning unit 770 and the filter unit 130.

The movable part 750 may move from a standby position to a dust compression position.

In the standby position, the cleaning unit 770 waits at a position away from the filter unit 130 and moves to the dust compression position during the cleaning process, thereby cleaning the outer surface of the filter unit 130.

The cleaning unit 770 may include a cleaning end 771a.

The cleaning end 771a may contact the outer surface of the filter unit 130 during the cleaning process.

In the present embodiment, since the cleaning unit 770 is formed of an elastically deformable material, the cleaning unit 770 is in contact with the filter unit 130 when the cleaning unit 770 descends and the cleaning end 771a comes into contact with the filter unit 130. The filter unit 130 is elastically deformed outward in the radial direction, and the cleaning end 771a may be in contact with the filter unit 130 in the elastically deformed state.

Therefore, when the cleaning part 770 descends while the cleaning end 771a is in contact with the circumference of the filter part 130, the cleaning end 771a is dust attached to the outer surface of the filter part 130. Will be removed.

In the present embodiment, since the cleaning end 771a is moved in contact with the filter unit 130, the cleaning unit 770 adjusts the eccentricity of the movable unit 750 while the movable unit 750 is moved up and down. Can be reduced.

For example, in a state in which the movable part 750 is inclined with respect to the horizontal direction, a contact force between a part of the cleaning end 771a and the filter part 130 is increased, so that the cleaning end 771a is deformed. The inclination of the movable part 750 may be reduced.

The cleaning unit 770 may include a first body 771 and a second body 772 extending upward from the first body 771.

The thickness of the second body 772 may be thinner than that of the first body 771. The second body 772 may be coupled to the lower side of the frame 760.

For example, the cleaning unit 770 may be coupled to the frame 760 by inserting injection.

The cleaning part 770 may further include a recessed part 773 that is recessed downward from the top. A lower extension part 761a extending from the frame 760 may be positioned in the recessed part 773.

The lower extension portion 761a positioned in the recessed portion 773 may be aligned with the suction passage.

The frame 760 may include a frame body 761 supporting the cleaning unit 770.

In the standby position, a part of the frame body 761 may contact the outer surface of the air guide 170. A part of the frame body 761 may surround the outer surface of the air guide 170 in a circumferential direction.

For example, the frame body 761 may include a first body 762a surrounding an outer surface of the air guide 170. The first body 762a may also be referred to as a guide cover part.

In the standby position, an upper end portion 762b of the first body 762a among the frame bodies 761 may be positioned highest.

The frame body 761 may further include a second body 762c whose height is lowered as it moves away from the first body 762a.

The first body 762a may be inclined to have a first inclination angle with respect to the horizontal plane. The first body 762a may be inclined in a direction closer to the axis A1 of the cyclone flow from an upper side to a lower side.

As the second body 762c is further away from the first body 762a, an inclination angle with respect to the horizontal plane may decrease.

Accordingly, the second body 762c may be spaced apart from the air guide 170.

The frame body 761 may further include a third body 762d extending from the second body 762c. The inclination angle of the third body 762d with respect to the horizontal plane may increase as the distance from the second body 762d increases.

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

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

The frame body 761 may include a fourth body 762f that is inclined from the upper end 762e of the third body 762d toward the center of the frame 760.

The inclination direction of the fourth body 762f may be the same as the inclination direction of the first body 762b.

At least a portion of the fourth body 762f may contact the outer peripheral surface of the air guide 170.

An outer wall 763 extending upward may be provided on an outer peripheral surface of the second body 726c. The height of an upper end of at least a portion of the outer wall 763 may decrease toward the third body 762d.

The lower extension part 761a may extend downward from the lower side of the first body 762a.

In this case, the inclination angle of the lower extension part 761a is greater than the inclination angle of the first body 762a with respect to the horizontal plane.

Accordingly, the air that meets the first body 762a may flow downwardly inclined, and may smoothly flow downward by the lower extension part 761a.

The frame 760 may further include a lower extension wall 766 extending downward from the frame body 761.

The lower extension wall 766 may be formed to be rounded in the circumferential direction of the frame 760.

The lower extension wall 766 serves to pressurize the dust stored in the dust bin 112 downward while the movable part 750 descends.

For example, the lower extension wall 766 may be located in a portion of the frame body 761 where the outer wall 763 is formed.

The frame 760 may further include a coupling portion 767 extending outward from the lower extension wall 766.

The coupling part 767 may protrude from the lower extension wall 766 in a horizontal direction. For example, the coupling part 767 may extend in a horizontal direction from the lower end 766a side of the lower extension wall 766.

The second transmission 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 transmission part 730 may be coupled to pass through the buffer part 734. In a state in which the shock absorbing part 734 is coupled with the second transmission part 730, the shock absorbing part 734 may be mounted on the upper surface of the coupling part 767.

The second transmission part 730 may penetrate the upper wall of the protruding body 180.

The buffer part 734 absorbs the shock generated in the process of contacting the upper wall of the protruding body 180 while the movable part 750 moves from the dust compression position to the standby position, thereby generating noise. Can be reduced.

The frame 760 may further include a frame guide 765 extending downward from the frame body 761.

For example, the frame guide 765 may extend downward from the outer peripheral surface of the first body 762a.

The frame guide 765 may include a planar guide surface 765a. The guide surface 765a may guide a helical flow of air in a process in which air is introduced through the suction unit 5.

The lower end 766a of the lower extension wall 766 is positioned higher than the lower end 765b of the frame guide 765 and the lower end 765b of the frame guide 765.

10 is a side view of an air guide according to an embodiment of the present invention. 11 is a view showing an arrangement relationship between the movable part and the air guide at the standby position of the movable part.

10 and 11, the air guide 170 may include a guide wall 171. The inner space of the guide wall 171 may form a flow path for guiding the air discharged from the second cyclone part 140.

The guide wall 171 may be arranged to surround the axis A1 of the cyclone flow.

The guide wall 171 may be formed in a ring shape, for example, and at least a portion thereof may be reduced in diameter from the top to the bottom.

The guide wall 171 may include a first mounting portion 171a for mounting a part of the frame body 761.

The first mounting portion 171a may be formed as the outer peripheral surface of the guide wall 171 is depressed toward the center.

The first body 762a of the frame body 761 may be mounted on the first mounting part 171a.

The guide wall 171 may further include a second seating portion 171b. The second mounting portion 171b may be formed as the outer peripheral surface of the guide wall 171 is depressed toward the center.

A fourth body 762f may be seated in the frame body 761 on the second seating portion 171b.

In a state in which the frame body 761 is seated on the guide wall 171, the upper end 762b of the first body 762a is positioned lower than the upper end 171c of the guide wall 171.

The air guide 170 may further include an extension wall 172 disposed so that the contact end 771a of the cleaning unit 770 faces at the standby position.

The extension wall 172 may extend downward from the lower end of the guide wall 171.

The extension wall 172 may be located under the first and second seating portions 171a and 171b.

The air guide 170 may further include a coupling wall 174 extending below the extension wall 172.

The second cyclone part 140 may be coupled to the coupling wall 174.

A coupling protrusion 175 may be formed on the outer circumferential surface of the coupling wall 174. The coupling protrusion 175 may be accommodated in a protrusion groove (not shown) of the second cyclone part 140.

The air guide 170 may further include a fastening boss 178 extending upward from an inner circumferential surface of the guide wall 171. The air guide 170 may be fastened to a component in the main body 2 by the fastening boss 178.

12 is a view of the suction opening from the outside of the body. 13 is a cross-sectional view taken along 13-13 of FIG. 5. 14 is a cross-sectional view taken along 14-14 of FIG. 12.

12 to 14, the main body 2 may further include a suction guide 12b for guiding air toward the suction opening 12a. The suction guide 12b may be coupled to the suction part 5.

A flow guide 52 may be provided in the suction part 5. The flow guide 52 guides air and dust to flow toward the inner circumferential surface 110a of the first cyclone part 110.

The frame guide 765 may extend in the same or parallel to the extension direction of the flow guide 52.

For example, an extension line A4 extending in a tangential direction of the first housing 10 (or first cyclone part 110) and an extension line A3 of the frame guide 765 (or guide surface 765a) ) Can be side by side.

When looking at the suction opening 12a from the outside of the main body 2, at the standby position of the movable part 750, a part of the movable part 750 may be aligned with the suction opening 12a.

For example, a part of the frame 760 and a part of the cleaning part 770 may be aligned with the suction opening 12a.

At least a portion of the first body 762a in the frame 760 may be aligned with the suction opening 12a. The first body 762a may look at the suction opening 12a from a position spaced apart from the suction opening 12a.

Of the guide wall 171, the upper end 762b of the first body 762a is so that a portion positioned higher than the upper end 762b of the first body 762a is not aligned with the suction opening 12a. , It may be located at the same height or higher than the upper end 12c of the suction opening 12a.

A boundary portion between the upper end 762b of the first body 762a and the guide wall 171 may be positioned higher than the upper end 12c of the suction opening 12a.

In the standby position of the movable part 750, the movable part 750 is restricted from moving upward, and can be moved downward by an external force.

If the upper end 762b of the first body 762a is positioned lower than the upper end 171c of the guide wall 171, air or dust flows toward the upper end 762b of the first body 762a. If so, the flow force of air acts as an external force for moving the first body 762a downward, so that a gap between the first body 762a and the guide wall 171 is widened.

When the gap between the guide wall 171 and the first body 762a opens, there is a problem in that the movable part 750 is not positioned in the correct position as air or dust is introduced into the gap.

When the movable part 750 is not positioned in the correct position, there is a disadvantage that the movable part 750 does not move smoothly downward.

In addition, when the movable part 750 is not positioned in the correct position, the movable part 750 acts as a flow resistance of air and dust sucked through the suction opening 12a, thereby deteriorating dust separation performance.

However, according to the present invention, the first body 762a so that the portion positioned higher than the upper end 762b of the first body 762a in the guide wall 171 is not exposed through the suction opening 12a. As the height of the movable unit 750 is set, the movable unit 750 can wait at the correct position.

The suction opening 12a may be aligned with at least a portion of the frame guide 765. The frame guide 765 may guide air and dust sucked through the suction opening 12a.

Air guided by the frame guide 765 may flow along the outer peripheral surface of the first body 762a.

At least a portion of the first body 762a may be inclined in a direction away from the suction opening 12a from an upper side to a lower side. That is, as the first body 762a goes from the top to the bottom, it inclines in a direction closer to the axis A1 of the cyclone flow.

Accordingly, air or dust guided by the frame guide 765 and in contact with the first body 762a, air or dust in contact with the first body 762a immediately after passing through the suction opening 12a, or The dust may smoothly move downward by the inclination of the first body 762a.

When air or dust in contact with the first body 762a is smoothly moved downward, the flow of dust or air to a boundary portion between the first body 762a and the air guide 170 may be prevented.

In addition, air flowing along the first body 762a may smoothly flow downward by the lower extension portion 761a.

Meanwhile, the upper end of the mesh unit 132 is positioned lower than the lower end 12d of the suction opening 12a to prevent the air sucked through the suction opening 12a from directly passing through the mesh unit 132 Can be.

In the standby position, the contact end 771a of the cleaning unit 770 may be positioned higher than the upper end of the mesh unit 132. Accordingly, the contact end 771a of the cleaning unit 770 may be prevented from blocking the mesh unit 132.

The height H2 of the frame 760 aligned with the suction opening 12a may be lower than the height H1 of the suction opening 12a.

Accordingly, a part of the cleaning unit 770 may also be aligned with the suction opening 12a.

For example, the contact end 771a of the cleaning unit 770 may be positioned higher than the lower end 12d of the suction opening 12a.

If the contact end 771a of the cleaning part 770 is positioned lower than the lower end 12d of the suction opening 12a, the mesh part 132 spaced apart from the contact end 771a is the suction opening There is a disadvantage in that the height of the main body 2 increases due to the distance from (12a).

On the other hand, as in the present invention, when the contact end 771a of the cleaning unit 770 is positioned higher than the lower end 12d of the suction opening 12a, the upper end of the mesh unit 132 is the suction opening ( While being positioned lower than the lower end 12d of 12a), it may be positioned closer to the lower end 12d, so that the height of the main body 2 may be prevented from increasing.

The longer the separation distance between the contact end 771a and the mesh part 132 is, the longer the distance that the contact end 771a must move to contact the mesh part 132 increases.

The height H2 of the frame 760 aligned with the suction opening 12a so that the separation distance between the contact end 771a and the mesh part 132 is reduced is the height of the suction opening 12a ( It can be greater than 1/2 of H1).

In the standby position of the movable part 750, the contact end 771a of the cleaning part 770 may be located closer to the lower end 12d than the upper end 12c of the suction opening 12a.

As an example, the lower extension portion 761a of the frame body 760 may be aligned with the suction opening 12a.

Accordingly, while the cleaning unit 770 connected to the frame body 761 is prevented from coming into contact with the filter unit 730, air and dust introduced into the frame body 760 may be sufficiently guided.

Since the height of a part of the cleaning part 770 located under the lower extension part 761a is smaller than the height of the cleaning part 770 of the other part, relative deformation of the frame body 761 due to the contact of air and dust Can be minimized.

Accordingly, a gap between the frame body 761 and the cleaning unit 770 may be prevented.

The lower end 765b of the frame guide 765 may be positioned lower than the contact end 771a of the cleaning unit 770. For example, the lower end 765b of the frame guide 765 may be positioned at the same height or lower than the lower end 12d of the suction opening 12a.

Accordingly, the frame guide 762 can guide the flow of the air flowing throughout the height of the suction opening 12a.
