Description

Cleaner {Cleaner}

This specification relates to a cleaner.

A vacuum cleaner is a device that performs cleaning by inhaling or wiping dust or foreign objects in the area to be cleaned.

The vacuum cleaner may be divided into a manual vacuum cleaner for performing cleaning while the user directly moves the vacuum cleaner, and an automatic vacuum cleaner that performs cleaning while driving on its own.

In addition, the manual vacuum cleaner may be classified into a canister type vacuum cleaner, an upright type vacuum cleaner, a handheld vacuum cleaner, a stick vacuum cleaner, and the like, depending on the type of the vacuum cleaner.

Prior Literature 1: Korean Patent Publication No. 10-2011-0106917

Prior document 1 discloses a handheld vacuum cleaner.

The handheld vacuum cleaner includes a separating device for separating garbage and dust from the air stream.

The separation device includes a centrifuge having one or more cyclones.

The centrifuge comprises a first cyclone having a dust collector with a wall. A dust collector is disposed under the first cyclone, and the dust collector can be opened and closed by a base. The base is rotated by a hinge to open and close the dust collector.

The first cyclone has a plurality of through-holes, and includes a trapezoidal cover. Within the lid, the second cyclone communicates with the first cyclone.

In the case of the prior document 1, the air inside the first cyclone flows through the second cyclone after the air passes through the plurality of holes. In the process of the air passing through the plurality of holes, dust causes the plurality of holes in the cover to open. Will be blocked. The more the plurality of holes are blocked, the less air flow is smooth and the separation performance deteriorates.

Therefore, the user must periodically clean the cover. In the case of the prior document 1, after the user rotates the base to open the dust collector, the user must approach the cover and then clean the cover, so there is a disadvantage that the cover is not easy to clean.

In addition, in the case of the prior document 1, dust separated from the first cyclone and the second cyclone falls downward and accumulates on the upper side of the base.

If the operation of the cleaner is stopped while the dust separation process is performed by the cleaner, the separated dust is stored in a low density state in the dust collector.

In particular, since the dust separated by the first cyclone occupies too large a volume compared to its weight, there is a disadvantage in that the dust in the dust collector must be emptied frequently to maintain dust collection performance.

Prior Literature 2: Japanese Registered Patent No. 3699679

Prior Art 2 discloses a technique capable of compressing dust in a dust collecting case.

The dust collecting case, a dust separation chamber for separating dust from the air by centrifugal force, a dust receiving chamber for receiving dust introduced from the dust separation chamber, an intake cylinder located in the center of the dust separation chamber, and disposed outside the intake cylinder Includes filters.

The air in the dust separation chamber is introduced into the intake cylinder after passing through the filter.

An outer cylinder is provided outside the intake cylinder, a compression plate is provided below the outer cylinder, and brush hair is provided on the inner circumferential surface of the outer cylinder. A plurality of openings are formed in the outer cylinder so as not to interfere with air flow from the dust separation chamber into the intake cylinder.

For the operation of the outer cylinder, an operation lever is formed outward in the radial direction of the outer cylinder. The operation lever is located outside the dust separation chamber.

Therefore, when the user lowers the outer cylinder with the compression plate by operating the operation lever, the brush hair on the inner surface of the outer cylinder cleans the filter of the suction cylinder outer circumference, and the compression plate compresses the dust stored in the dust receiving chamber.

However, according to the prior art document 2, since the outer cylinder is configured to surround the entire intake cylinder without the operation lever being operated, a plurality of openings are formed in the outer cylinder to allow air to pass through the outer cylinder.

However, even if a plurality of openings are present in the outer cylinder, a portion in which the opening is not formed acts as a flow resistance of air, thereby deteriorating the flow performance of air.

In addition, since the outer cylinder is located outside the intake cylinder, since the dust in the dust separation chamber contacts the outer cylinder when the operation lever is not operated, the outer cylinder itself is contaminated and additional cleaning of the outer cylinder is required.

Further, according to the prior art document 2, since the operation lever is located outside the distant separation chamber, in order to move the operation lever up and down, the dust separation chamber must be provided with a slot in the vertical direction.

Since the operation lever does not cover the entire slot, air and dust inside the dust separation chamber leak out through the slot.

In addition, in the case of the prior document 2, since the structure for moving up and down is not eccentric and does not exist in the process of moving the outer cylinder up and down, there is a problem that the vertical movement of the outer cylinder is not smooth.

In addition, in the case of the prior document 2, since the operation lever can be operated after separating the dust collecting case from the cleaner body, there is a disadvantage that the user is troublesome.

The present invention provides a cleaner capable of cleaning the filter unit by operating the cleaning mechanism.

In addition, the present invention provides a cleaner that can stably descend in the cleaning process of the cleaning mechanism.

In addition, the present invention provides a cleaner in which the cleaning mechanism is prevented from acting as a flow resistance of air while the cleaning mechanism is positioned in the standby position.

In addition, the present invention provides a cleaner in which foreign substances are prevented from entering the gap between the movable part and the air guide in a state where the cleaning mechanism is positioned in the standby position.

In addition, the present invention provides a cleaner in which a phenomenon in which an end portion is folded and deformed in the process of ascending after the cleaning unit descends is prevented.

The vacuum cleaner according to one aspect is disposed at a lower portion of the cyclone portion, a cyclone portion for separating the dust from the dust sucked through the suction portion, and a suction portion for sucking air, and separated from the cyclone portion A body including a dust container for storing dust, a filter unit for filtering air in a process in which dust separated air passes, and a main body including a dust container, and is movably disposed inside the cyclone unit, A movable part having a cleaning part for cleaning the outer circumference of the filter part in a moving process, and an operation part disposed outside the main body and operated to move the movable part; And a transmission part penetrating the main body and connecting the movable part and the operating part.

In the present exemplary embodiment, the movable part may be prevented from acting as an air flow resistance by waiting in a standby position, which is a position not surrounding the periphery of the filter part, during dust separation in the cyclone part.

The movable part may include a recessed part recessed in a direction away from the suction part and at least partially facing the suction part. The movable part may include at least two parts having different radii by the recessed part.

When the operation unit is operated, the movable unit moves to remove the dust on the outer surface of the filter unit, so that the user can easily clean the filter unit.

The movable part may further include a frame supporting an upper part of the outer circumferential surface of the cleaning part and a core part supporting an upper part of the inner circumferential surface of the cleaning part and coupled with the cleaning part and the frame.

The depression portion may be formed at positions corresponding to each of the frame, the core portion, and the cleaning portion.

The frame may include an inner body supporting the cleaning part and an outer body surrounding at least a portion of the inner body from outside the inner body.

The depression may be formed in a portion of the inner body that is not surrounded by the outer body.

The height of the portion where the depression is formed in the inner body may be lower than the height of the portion where the depression is not formed.

The suction part may be provided with an inflow guide for guiding the flow of air so that the cyclone flow occurs in the cyclone part. The frame may include a frame guide extending in parallel with the inlet guide to guide air flowing along the inlet guide.

The frame guide connects the inner body and the outer body, and a lower portion of the frame guide may be positioned lower than a lower portion of the outer body.

The main body includes a first body for generating the cyclone flow, and in the frame, the first extension line (A3) of the inflow guide and the first extension line (A3) are parallel to the first body. The depression may be located in a portion positioned between the second extension line A4 extending in the tangential direction.

The frame may include a pressure rib extending downward from an outer lower end of the frame, and a connection portion extending radially outward from a lower portion of the pressure rib and connected to the transmission unit.

The pressure rib may extend downward from the bottom of the outer body.

The second cyclone unit for separating dust from the air discharged from the cyclone unit may be further included, and the filter unit may be disposed to surround the second cyclone unit.

The main body, located on the upper side of the filter unit, further includes an air guide for guiding the flow of air past the filter unit, and in the standby position of the movable unit, the movable unit may surround the air guide.

The movable portion may include a frame supporting an upper portion of the outer peripheral surface of the cleaning portion, and a core portion supporting an upper portion of the inner peripheral surface of the cleaning portion and coupled with the cleaning portion and the frame.

In this embodiment, a plurality of points of the movable part contact with the air guide, and thus dust can be prevented from entering the gap between the movable part and the outer circumferential surface of the air guide.

For example, the outer peripheral surface of the air guide may include a contact surface in contact with the cleaning surface. The air guide includes a contact protrusion formed to protrude in a circumferential direction from an upper portion of the outer circumferential surface, and the frame may include a protrusion seating groove in which the contact protrusion is seated. Each of the contact protrusion and the protrusion seating groove may be formed in a ring shape.

The outer circumferential surface diameter of the discharge guide located below the air guide is formed smaller than the outer circumferential surface of the air guide, and the outer circumferential surface diameter of the filter portion located below the outer circumferential surface of the discharge guide is formed smaller, so that the cleaning part is stable without interference with surrounding structures. By descending, the filter can be cleaned.

The cleaning surface of the cleaning part is a vertical surface for making surface contact with the outer circumferential surface of the filter part, and the bottom surface of the cleaning part is a horizontal surface extending radially outward from the bottom of the cleaning surface.

The cleaning unit includes a first inner inclined surface inclined upward from the upper end of the cleaning surface in a radial direction, and a first outer inclined surface inclined upward in a radial direction from an outer end of the lower surface, wherein the first inner inclined surface is the It is separated from the outer peripheral surface of the filter unit.

According to the proposed invention, since the filter portion is cleaned while the cleaning portion of the movable portion is moved by pressing the operation portion, the hassle of manually cleaning the filter portion is eliminated.

In addition, the cleaning mechanism acts as a flow resistance of air because the movable part waits in a standby position, which is a position not surrounding the circumference of the filter part, in a state in which the cleaning mechanism is not used, that is, in the dust separation process within the dust separation unit Can be prevented.

In addition, since the outer circumferential surface diameter of the discharge guide located below the air guide is formed smaller than the outer circumferential surface of the air guide, and the outer circumferential surface diameter of the filter portion positioned lower than the outer circumferential surface of the discharge guide is formed smaller, the cleaning part does not interfere with the structure. There is an advantage that the filter part can be cleaned by descending stably.

In addition, by including a depression in which the movable portion is recessed inward, it can be minimized that the movable portion acts as a flow resistance of air when air is introduced through the suction portion.

5 is a view showing the arrangement of the movable part, the filter part, and the air guide of the cleaning mechanism.

1 to 5, the cleaner 1 according to an embodiment of the present invention may include a main body 2. The body 2 may include a suction part 5 through which air containing dust is sucked. The suction part 5 may guide air containing dust to the body 2.

The cleaner 1 may further include a handle portion 3 coupled to the main body 2. The handle part 3 may be located on the opposite side of the suction part 5 as an example from the main body 2. However, the positions of the suction part 5 and the handle part 3 are not limited thereto.

The main body 2 may separate the dust sucked into the inside through the suction part 5 and store the separated dust.

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.

The air and dust sucked through the suction part 5 spirally flow along the inner circumferential surface of the first cyclone part 110.

The dust separation unit may further include a second cyclone unit 140 for separating 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 arranged in parallel. Air may be divided into the plurality of cyclone bodies 142 and pass through.

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

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

For example, the body 2 may include a first body 10 having a substantially cylindrical shape, and a second body 20 having a substantially cylindrical shape coupled to an upper side of the first body 10. .

A dust bin that stores the dust separated from the first cyclone portion 110 by the upper portion of the first body 10 defines the first cyclone portion 110 and the lower portion of the first body 10 is separated from the first cyclone portion 110. (112) is defined.

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

The main 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 air separated from dust in the first cyclone unit 110 to the second cyclone unit 140. The filter unit 130 filters dust in the process of passing air.

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 portion 132 filters air, dust may accumulate on the mesh portion 132, and thus the mesh portion 132 needs to be cleaned.

Therefore, in the present invention, the cleaner 1 may further include a cleaning mechanism 70 for cleaning the filter unit 130.

The cleaning mechanism 70 includes a movable part 730 movable within the main body 2, an operation part 710 operated by a user to move the movable part 730, and an operating force of the operating part 710. It may include a transfer unit 720 for transferring to the movable unit 730.

The operation unit 710 may be disposed outside the main body 2.

The handle part 3 may include a handle body 30 for gripping a user, and a battery housing 60 disposed under the handle body 30 and accommodating the battery 600. .

The handle body 30 may guide the movement of the manipulation unit 710 while covering a part of the manipulation unit 710.

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.

Therefore, the manipulation unit 710 can be easily operated with the left hand that does not grip the handle body 30.

The operation 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.

Therefore, the operation unit 710 can also be moved in the vertical direction while the dust container 112 is placed on the floor.

A slot 310 may be formed in the handle body 30 to move the manipulation unit 710. The slot 310 may also extend in a direction parallel to the extending direction of the axis A1 of the cyclone flow of the first cyclone unit 110.

In this embodiment, since the extending direction of the axis A1 of the cyclone flow is an up-down direction as 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 It can be understood as.

Referring to FIG. 2, the diameter D1 of the main body 2 may have a longer horizontal length L1 of the handle part 3. And, the handle portion 3 may be coupled to the body 2 such that the left and right centers of the handle portion 3 coincide with the centers of the body 2.

For example, the manipulation unit 710 may be located at a boundary portion where the main body 2 and the handle unit 3 are in contact.

When the cleaner 1 is placed so that the main body 2 and the handle part 3 contact the floor F together, due to a difference in the diameter of the main body 2 and the left and right lengths of the handle part 3, A space is formed between the outer circumferential surface of the body 2 and the outer circumferential surface of the handle part 3 and the bottom F, and the manipulation unit 710 may be positioned in the space.

In this state, the operation unit 710 is spaced apart from the floor (F). Therefore, in the process of placing the cleaner 1 on the floor F, the manipulation unit 710 collides with the floor F to prevent the manipulation unit 710 from being damaged or the manipulation unit 710 being unintentionally operated. Can be.

The transmission unit 720 may be formed, for example, in the form of a cylindrical bar, and the manipulation unit 710 may be coupled to an upper end of the transmission unit 720. That is, the transmission unit 720 may have a horizontal cross-section.

In addition, the transmission unit 720 may also extend in a direction parallel to the extending direction of the axis A1 of the cyclone flow of the first cyclone unit 110.

Since the movable part 730 is located in the main body 2, and the operating part 710 is located outside the main body 2, the transfer part 720 is connected to the movable part 730 and the operating part 710. A part of) may be located outside the main body 2 and another part may be located inside the main body 2. That is, the transmission unit 720 may penetrate the body 2. In addition, a portion of the transmission part 720 positioned outside the main body 2 may be covered by the handle part 3.

The body 2 may further include a guide body 180 for guiding the transmission unit 720. The guide body 180 is present, for example, in a form protruding from the outside of the first body 10.

The guide body 180 may extend in a direction parallel to the extending direction of the axis A1 of the cyclone flow of the first cyclone unit 110.

The guide body 180 communicates with the inner space of the first body 10, and the transfer part 720 can move within the guide body 180.

The detailed structure of the guide body 180 will be described later with reference to the drawings.

The body 2 may further include a suction motor 220 for generating suction power. The suction force generated by the suction motor 220 may act on the suction part 5.

The suction motor 220 may be located in the second body 20.

The suction motor 220 may be located above the dust container 112 and the battery 600 based on an extending direction of an axis of the cyclone flow of the first cyclone unit 110. The operation unit 720 may be positioned at the same height as a part of the suction motor 220 or higher than the suction motor 220.

The body 2 may further include an air guide 170 for guiding air discharged from the second cyclone unit 140 to the suction motor 220.

The second cyclone unit 140 may be coupled to the lower side of the air guide 170. The filter unit 130 surrounds the second cyclone unit 140 in a state where it is combined with the second cyclone unit 140.

Therefore, the filter unit 130 may also be located under the air guide 170. The movable part 730 may be disposed at a position surrounding the air guide 170 in a state where the operating part 710 is not operated.

The movable part 730 may include a cleaning part 740 for cleaning the filter part 130.

In this embodiment, the position of the cleaning mechanism 70 in the state in which the operation unit 710 has not been operated may be referred to as a standby position.

In the standby position of the cleaning mechanism 730, all of the cleaning part 740 may be disposed in a direction in which air passes through the filter part 130 so as not to overlap the filter part 130.

For example, in the standby position, all of the cleaning unit 740 may be positioned higher than the filter unit 130. Therefore, in the standby position, the cleaning part 740 may be prevented from acting as a flow resistance in the process of air passing through the filter part 130.

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

The lower side of the dust guide 160 may be seated on the body cover 114. The dust guide 160 is spaced apart from the inner circumferential surface of the first body 10, the first dust storage for storing the dust separated from the first cyclone unit 110 in the inner space of the first body 10 It is divided into a part 120 and a second dust storage part 122 that stores dust separated from the second cyclone part 140.

The inner circumferential surface of the first body 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 Define

<Cleaning mechanism>

Hereinafter, the cleaning mechanism 70 will be described in detail.

6 and 7 are perspective views of a cleaning device according to an embodiment of the present invention, and FIG. 8 is an exploded perspective view of the cleaning device according to an embodiment of the present invention.

9 is a perspective view of a cleaning unit according to an embodiment of the present invention, FIG. 10 is a perspective view of a core unit according to an embodiment of the present invention, and FIG. 11 is a perspective view of a frame according to an embodiment of the present invention as viewed from above , FIG. 12 is a perspective view of a frame according to an embodiment of the present invention as viewed from below.

13 is a cross-sectional view taken along line B-B of FIG. 6, and FIG. 14 is a cross-sectional view taken along line C-C of FIG. 6.

6 to 14, the movable part 730 includes a cleaning part 740 for cleaning the filter part 130, a frame 760 supporting an outer circumference of the cleaning part 740, and the A core portion 750 supporting the inner circumference of the cleaning portion 740 may be included.

<Cleaning Department>

The cleaning unit 740 may be formed of an elastically deformable material. For example, the cleaning part 740 may be formed of a rubber material. The cleaning part 740 may be formed in a ring shape so that the cleaning part 740 can clean the entire circumference of the cylindrical filter part 130. As another example, the cleaning part 740 may be formed of silicon or a fiber material.

Then, the cleaning unit 740 waits at a position away from the filter unit 130 in the standby position, and moves while wiping the outer surface of the filter unit 130 in the cleaning process.

The cleaning unit 740 may include an inner circumferential surface, an outer circumferential surface, a lower surface 749 and an upper surface 746.

The inner circumferential surface of the cleaning unit 740 may include a cleaning surface 741 that contacts the outer surface of the filter unit 130 in the cleaning process. The cleaning surface 741 is a surface facing the filter unit 130 and may be a vertical surface.

Accordingly, when the cleaning unit 740 descends while the entire cleaning surface 741 is in contact with the circumference of the filter unit 130, the cleaning surface 741 removes dust adhering to the outer surface of the filter unit 130. Will be removed.

The lower surface 749 is a horizontal surface, and the cleaning surface 741 extends upward from an inner end of the lower surface 749. Therefore, the lower surface 749 and the cleaning surface 741 are vertical.

As described above, when the cleaning surface 741 is a vertical surface and the lower surface 749 is formed as a horizontal surface perpendicular to the cleaning surface 741, the cleaning surface 741 and the cleaning surface 741 are raised in the process of rising after the cleaning unit 740 descends. A phenomenon in which the boundary portion of the lower surface 749 is dried inward by friction with the filter portion 130 can be prevented.

When the cleaning surface 741 and the lower surface 749 are dried inward, the contact area between the cleaning surface 741 and the filter unit 130 is reduced to clean the filter unit 130 by the cleaning surface 741. The performance decreases, but according to the present invention, such a phenomenon can be prevented.

The diameter of the cleaning surface 741 is formed smaller than the diameter of the filter unit 130. In this embodiment, since the cleaning part 740 is formed of an elastically deformable material, the cleaning part 740 is the process in which the cleaning part 740 descends and the cleaning surface 741 contacts the filter part 130. Elastically deformed outward in the radial direction of the filter unit 130, the cleaning surface 741 may contact the filter unit 130 in an elastically deformed state.

That is, the cleaning surface 741 may compress the filter unit 130 while the cleaning surface 741 is in contact with the filter unit 130. As described above, since the cleaning surface 741 cleans the filter unit 130 in a state where the filter unit 130 is compressed, dust attached to the filter unit 130 can be effectively removed from the filter unit 130. have.

In addition, since the cleaning part 740 is formed of a material that is elastically changeable, the entire circumference of the cleaning surface 741 compresses the filter part 130, so that the axis of the cyclone flow in the process of the cleaning part 740 descending With respect to (A1), even if the center of the cleaning unit 740 is inclined, the cleaning surface 741 of the cleaning unit 740 is maintained in a compressed state of the filter unit 130, so that the cleaning of the filter unit 130 is possible. do.

As the cleaning performance of the filter unit 130 is improved, the vertical length of the cleaning surface 741 is a radial length of the lower surface 749 such that elastic deformation is good at the cleaning surface 741 side in the cleaning unit 740 ( It may be formed longer than the left and right length in the drawing).

The inner circumferential surface of the cleaning part 740 may further include a first inner inclined surface 742 extending upwardly in a radial direction from the top of the cleaning surface 741.

Since the first inner inclined surface 742 is inclined upward to the outside, the inner diameter of the first inner inclined surface 742 portion in the cleaning part 740 becomes larger toward the upper side. In addition, the first inner inclined surface 742 is spaced apart from the outer circumferential surface of the filter unit 730.

The outer circumferential surface of the cleaning unit 740 may further include a first outer inclined surface 748 extending upwardly inclined radially outward from the outer end of the lower surface 749.

At this time, the inclination angle of the first outer inclined surface 748 is greater than the inclined angle of the first inner inclined surface 742 based on the vertical line.

Therefore, when viewed in a vertical section, the thickness between the first inner inclined surface 742 and the first outer inclined surface 748 in the cleaning unit 740 is reduced toward the lower side.

This is to ensure that the elastic deformation of the cleaning part 740 is well performed in the process of the cleaning part 741 contacting the filter part 730 in the cleaning part 740.

The inner circumferential surface of the cleaning part 740 may further include an inner vertical surface 743 extending vertically from the first inner inclined surface 742.

The outer peripheral surface of the cleaning unit 740 may further include a first outer vertical surface 748a extending vertically upward from an upper end of the first outer inclined surface 748.

The length of the first outer vertical surface 748a is formed longer than the length of the inner vertical surface 743. In addition, the inner vertical surface 743 is disposed to face the first outer vertical surface 748.

In the cleaning part 740, the thickness between the first outer vertical surface 748a and the inner vertical surface 743 is the thickest. This is to ensure that the portion between the first outer vertical surface 748a and the inner vertical surface 743 in the cleaning part 740 is not deformed but remains coupled with the frame 760 and the core part 750. to be.

An inclination angle of the second inner inclined surface 744 and the second outer inclined surface 748b may be substantially the same. Further, the inclination angle of the second inner inclined surface 744 may be substantially the same as the inclined angle of the first outer inclined surface 748a.

The outer peripheral surface of the cleaning unit 740 may further include a second outer vertical surface 748c extending vertically upward from the top of the second outer inclined surface 748b.

The upper end of the second outer vertical surface 748c and the upper end of the second inner inclined surface 744 may be connected by an upper surface 746.

The top of the second outer vertical surface 748b and the top of the second inner inclined surface 744 may be located at the same height. Therefore, the upper surface 746 of the cleaning unit 740 is a horizontal surface.

Coupling projections 745 for coupling with the core portion 750 may be formed on the second inner inclined surface 744.

A plurality of engaging projections 745 may be arranged to be spaced apart in the circumferential direction of the cleaning unit 740 so that the coupling force between the core unit 750 and the cleaning unit 740 is increased.

Each coupling protrusion 745 may protrude in the horizontal direction from the second inner inclined surface 744. That is, the extending direction of the engaging projection 745 forms a predetermined angle with the normal of the second inner inclined surface 744.

When the engaging projection 745 extends in the horizontal direction from the second inner inclined surface 744, the engaging projection 745 is separated from the core portion 750 in the process of moving the cleaning unit 740 in the vertical direction. Can be effectively prevented.

Meanwhile, a part of the first outer inclined surface 748 in the cleaning part 740 may be formed by being recessed inward. For example, the first outer inclined surface 748 may include a depression 747.

The function and position of the depression 747 will be described later with reference to the drawings.

<Core part>

The core part 750 may be in contact with a portion of the upper surface 746 and the inner circumferential surface of the cleaning part 740.

For example, the core portion 750 may include an outer inclined surface 758 in contact with the second inner inclined surface 744 of the cleaning part 740.

The outer inclined surface 758 may be inclined upward from the lower side to the upper radial direction.

The core portion 750 may further include an inner vertical surface 751 extending vertically upward from a lower end of the outer inclined surface 758. The inner vertical surface 751 may be aligned with the inner vertical surface 743 of the cleaning part 740 in the vertical direction.

For example, the inner vertical surface 751 of the core portion 750 and the inner vertical surface 743 of the cleaning portion 740 may be surfaces that are continuous in the vertical direction.

The core portion 750 may further include an inner inclined surface 752 that is inclined upward from the upper end of the inner vertical surface 751 toward the outside. The inclined angle of the inner inclined surface 752 may be substantially the same as the inclined angle of the outer inclined surface 758.

The core portion 750 may further include a coupling hole 753 into which the coupling protrusion 745 of the cleaning portion 740 is inserted. For example, a plurality of coupling holes 753 may be disposed spaced apart in the circumferential direction of the core portion 750.

In each of the coupling holes 753, a part penetrates the outer inclined surface 758 and the inner inclined surface 752, and the other part penetrates the outer inclined surface 758 and the inner vertical surface 743.

The core portion 750 may further include a horizontal surface 757 extending horizontally from the end of the outer inclined surface 758 to the outside.

The radial length of the horizontal surface 757 is longer than the radial length of the upper surface 746 of the cleaning part 740.

The horizontal surface 757 of the core portion 750 may contact the upper surface 746 of the cleaning portion 740. At this time, the front surface of the upper surface 746 of the cleaning part 750 may contact the horizontal surface 757 of the core part 750.

The core portion 750 may further include an outer vertical surface 756 extending vertically upward from an outer end of the horizontal surface 757.

The upper surface 754 of the core portion 750 may connect the upper end of the outer vertical surface 756 and the upper end of the inner inclined surface 752.

At this time, the top of the outer vertical surface 756 and the top of the inner inclined surface 752 may be located at the same height. Therefore, the upper surface 754 of the core portion 750 is a horizontal surface.

The core portion 750 may further include a hook coupling slot 755 for coupling the hook 782 of the frame 760.

A plurality of hook coupling slots 755 may be arranged to be spaced apart in the circumferential direction of the core portion 750 to increase the fastening force between the core portion 750 and the frame 760.

Each hook coupling slot 755 may be formed as the upper surface 754 of the core portion 750 is recessed downward. Alternatively, each hook coupling slot 755 may be formed to penetrate the upper portion of the outer vertical surface 756 and the upper portion of the inner inclined surface 752 in the horizontal direction.

In any case, the engaging hooks 782 of the frame 760 may be seated on the bottom surface of each hook engaging slot 755.

The core portion 750 may further include a depression portion 757 formed at a position corresponding to the depression portion 747 of the cleaning portion 740.

<Frame>

The frame 760 supports the cleaning part 740 and is combined with the core part 750 to fix the position of the cleaning part 740.

The frame 760 includes an inner body 761a supporting the cleaning part 740 and an outer body extending downward from an upper side of the inner body 761a and positioned outside the inner body 761a ( 761b).

The inner body 761a is formed to be inclined radially outward from the lower side to the upper side as a whole, and the outer body 761b has a shape extending vertically from the upper side to the lower side of the inner body 761a.

The inner body 761a may include an inner body lower surface 761. The inner body lower surface 761 may be, for example, a horizontal surface.

The inner body 761a may include a first inner vertical surface 761c vertically extending upward from an inner end of the inner body lower surface 761. The first inner vertical surface 761c may contact the first outer vertical surface 748a of the cleaning unit 740.

The inner body lower surface 761 is positioned higher than the lower surface 749 of the cleaning unit 740. Therefore, when viewed as a whole of the movable part 730, the lower surface 749 of the cleaning part 740 is located at the bottom.

The inner body 761a may further include a first inner inclined surface 761d that is inclined upward toward the outer side in the radial direction from the top of the first inner vertical surface 761c.

In addition, the inner body 761a may further include a second inner vertical surface 761e extending vertically upward from the top of the first inner inclined surface 761d.

In addition, the inner body 761a may further include a horizontal surface 780 extending in a horizontal direction from the top of the second inner vertical surface 761e to the outside.

A second outer inclined surface 748b of the cleaning unit 740 may be seated on the first inner inclined surface 761d.

A second outer vertical surface 748c of the cleaning unit 740 may be in contact with the second inner vertical surface 761e.

The horizontal surface 780 of the inner body 761a may be positioned at the same height as the upper surface 749 of the cleaning part 740.

Therefore, the horizontal surface 757 of the core portion 750 may be seated on the horizontal surface 780 of the inner body 761a and the upper surface 749 of the cleaning unit 740.

That is, a portion of the inner body 761a and a portion of the core portion 750 may be combined to surround an upper portion of the cleaning portion 740.

The inner body 761a may further include a second inner vertical surface 781 extending vertically upward from the outer end of the horizontal surface 780.

The second inner vertical surface 781 of the inner body 761a may be in contact with the outer vertical surface 756 of the core portion 750. At this time, the vertical length of the second inner vertical surface 781 is formed longer than the vertical length of the outer vertical surface 756 of the core portion 750.

Accordingly, the entire outer vertical surface 756 of the core portion 750 may contact the second inner vertical surface 781.

The coupling hook 782 may be formed on the second inner vertical surface 781 of the inner body 761a. A plurality of coupling hooks 782 may be disposed spaced apart in the circumferential direction from the second inner vertical surface 781.

Each coupling hook 782 may protrude toward the inside from an upper portion of the second inner vertical surface 781.

Therefore, according to the present embodiment, the upper side of the core portion 750 is restricted upward movement by the coupling hook 782, and the lower side of the core portion 750 is a horizontal surface 780 of the inner body 761a. ), The downward movement is restricted.

The outer body 761b is disposed outside the inner body 761a, but does not entirely surround the inner body 761a, but only partially surrounds it.

At this time, the portion where the outer body 761b is not formed is a portion adjacent to the suction part 5 in the body 2.

In addition, a recess 767 recessed inward may be formed in a portion of the inner body 761a that is not surrounded by the outer body 761b. The depression portion of the inner body 761a, the depression portion 757 of the core portion 750, and the depression portion 747 of the cleaning portion 740 may be formed at positions corresponding to each other.

The height of the portion where the depression 767 is formed in the inner body 761a may be lower than the height of the portion where the depression 767 is not formed.

At least some of the depressions 767, 757, and 747 in the movable portion 730 are arranged to face the suction portion 5 and may be recessed in a direction away from the suction portion 5.

The movable body 730 is lowered so that the relative deformation between the inner body 761a and the outer body 761b is prevented by the reaction force acting in the process of compressing the dust in the dust container 112, so that the inner body ( 761a) and the outer body 761b may be connected by one or more connecting ribs 769.

The frame 760 may further include a frame guide 765 extending downward from a boundary portion between the inner body 761a and the outer body 761b.

The vertical length of the frame guide 765 is longer than the vertical length of the inner body 761a and the outer body 761b. And, the lower end of the frame guide 765 is positioned lower than the inner body 761a and the outer body 761b.

The frame guide 765 may include a planar guide surface 765a. The guide surface 765a serves to guide the spiral flow of air in the process of air flowing into the first cyclone unit 110 through the suction unit 5. The arrangement of the frame guide 765 will be described later with reference to the drawings.

Since the lower end of the frame guide 765 is positioned lower than the inner body 761a and the outer body 761b, the frame guide 765 is attached to the dust container 112 in the process of the movable part 730 descending. The stored dust can be pressed downward.

The frame 760 may further include a pressure rib 762 extending downward from the outer body 761b. The pressure rib 762 may be formed to be rounded in the circumferential direction.

The pressure rib 762 serves to press the dust stored in the dust container 112 downward while the movable part 730 descends.

At this time, since the pressing rib 762 is formed in a thin plate shape, a pressing area in which the pressing rib 762 presses dust is small. Accordingly, the frame 760 may further include one or more auxiliary ribs 762a protruding in an inner direction from the inner circumferential surface of the pressing rib 762 so that the compressed area of dust is increased.

To further increase the dust compression effect, a plurality of auxiliary ribs 762a may be arranged spaced apart from the pressure ribs 762 in the circumferential direction.

Each of the auxiliary ribs 762a extends below the connecting ribs 769, or separately from the connecting ribs 769, while connecting the inner body 761a and the outer body 761b, the pressing ribs 762 It can be extended to the side.

The auxiliary ribs 762a may include an inclined surface 762b so that the auxiliary ribs 762a can compress the dust and not interfere with the flow of air in the standby position.

For example, the inclined surface 762b may be inclined downward toward the outer side in the radial direction from the auxiliary rib 762a. That is, the protruding length of the auxiliary rib 762b may decrease toward the lower side.

In addition, the lower end of the auxiliary rib 762b may be positioned higher than the lower end of the pressure rib 762b.

The frame 760 may further include an extension portion 763 extending outward from the pressure rib 762 and a coupling portion 764 formed in the extension portion 763.

In this embodiment, the extension part 763 and the coupling part 764 may be referred to as a connection part for connecting the frame 760 to the transmission part 720.

The transmission part 720 may be connected to the coupling part 764.

For example, the extension part 763 may extend outward from the bottom of the outer circumferential surface of the pressure rib 762. At this time, the extension line of the extension portion 763 passes through the center of the frame 760.

Therefore, a moment may be prevented from occurring in the process of the operation force of the operation unit 710 being transmitted to the frame 760 by the transmission unit 720.

Left and right thicknesses of the extension portion 763 may be formed smaller than the diameter of the coupling portion 764.

The coupling portion 764 may be formed in a substantially cylindrical shape. A receiving groove 764a for receiving the transmission portion 720 may be formed in the coupling portion 764. The receiving groove 764a may be formed by being recessed downward from the upper surface of the engaging portion 764.

The transmission unit 720 may be formed in a long bar shape of a cylindrical shape as described above. This is to enable smooth movement of the transfer unit 720 when the transfer unit 720 moves while passing through the guide body 180.

Therefore, the lower end of the transmission unit 720 may be inserted into the receiving groove 764a on the upper side of the coupling unit 764.

The coupling part 764 may further include a seating surface 764b on which a lower end of the transmission part 720 accommodated in the receiving groove 764a is seated.

The fastening member S1 is fastened to the transfer part 720 at the lower side of the coupling part 764 while the transfer part 750 is accommodated in the receiving groove 764a and seated on the seating surface 764b. Can be. The fastening member S1 may be, for example, a bolt.

A receiving groove 764c in which the head of the bolt is accommodated may be formed at the bottom of the coupling portion 764. In addition, a fastening groove 722 for fastening the fastening member S1 is formed in the transmission part 720.

Therefore, the fastening member S1 may be fastened to the fastening groove 722 of the transmission unit 720 through a fastening hole 764d penetrating the receiving groove 764c and the seating surface 764b. .

In the state in which the transmission unit 720 is coupled to the coupling unit 764, the transmission unit 720 may be spaced apart from the outer circumferential surface (the outer circumferential surface of the outer body) of the frame 760.

In this embodiment, the cleaning part 740 may be integrally formed with the core part 750 and the frame 760 by double injection.

15 is a view showing a state in which the movable unit is in a standby position according to an embodiment of the present invention, and FIG. 16 is an enlarged view of part A of FIG.

15 and 16, the movable part 730 is disposed to surround the outer periphery of the air guide 170 in a standby position.

At this time, the outer circumferential surface of the air guide 170 is recessed inward so that the movable part 730 protrudes outward while the movable part 730 surrounds the outside of the air guide 170. (171) can be formed.

A portion of the movable part 730 may be accommodated in the accommodation space 171.

The outer circumferential surface of the air guide 170 may further include a contact surface 175 that the cleaning surface 741 of the cleaning part 740 contacts. The contact surface 175 is located below the receiving space 171 of the outer circumferential surface of the movable part 730.

At this time, the contact surface 175 may be a vertical surface disposed to face the cleaning surface 741. The vertical length of the contact surface 175 may be longer than the vertical length of the cleaning surface 741.

Accordingly, the entire surface of the cleaning surface 741 may be in contact with the contact surface 175 in the standby position.

In this embodiment, the outer diameter of the portion where the contact surface 175 is formed in the air guide 170 may be formed to be larger than the inner diameter of the portion where the cleaning surface 741 is formed in the cleaning unit 740.

Therefore, in the standby position, the cleaning part 740 is elastically deformed outward in the radial direction of the contact surface 175, and the cleaning surface 741 may be in contact with the contact surface 175 in an elastically deformed state.

That is, in the standby position, since the cleaning surface 741 is in the compressed state of the contact surface 175, the frictional force between the cleaning surface 741 and the contact surface 175 is increased and the manipulation unit 710 is not operated. The cleaning surface 741 may be prevented from sliding along the contact surface 175 in a non-contained state.

In the state where the movable part 730 is accommodated in the accommodating space 171 in the standby position, the air guide 170 is prevented from entering foreign substances between the movable part 730 and the outer circumferential surface of the air guide 170. A contact protrusion 172 may be included, and the frame 760 may include a protrusion seating groove 768 on which the contact protrusion 172 is seated.

The contact protrusion 172 may protrude downward from an upper portion of the outer circumferential surface of the air guide 170. The contact protrusion 172 may be continuously formed along the circumferential direction of the air guide 170. That is, the contact protrusion 172 may be formed in a ring shape.

The protrusion seating groove 768 may be formed as the upper edge of the frame 760 is recessed downward. The protrusion seating groove 768 may also be formed in a ring shape so that the ring-shaped contact protrusion 172 can be seated.

Accordingly, in the standby position, the cleaning surface 741 and the protrusion seating groove 768 that are spaced apart in the vertical direction contact the contact surface 175 and the contact protrusion 172 of the air guide 170, respectively. .

Therefore, two contact points prevent foreign matter from entering the gap between the air guide 170 and the movable part 730.

The upper side of the second cyclone unit 140 may be provided with a discharge guide 150 for guiding the discharge of dust and air separated from the second cyclone unit 140.

The discharge guide 150 may be coupled to the lower side of the air guide 170. A coupling space 175 in which an edge portion of the discharge guide 150 is positioned may be defined at a lower circumference of the air guide 170.

A portion of the air guide 170 may be seated on the upper surface 151 of the discharge guide 150 by the coupling space 175.

The air guide 170 extends substantially vertically downward from the inner end of the first surface 173 and the first surface 173 extending substantially horizontally from the lower end of the contact surface 175 to the inner direction. It may include a second side (174).

In addition, the first surface 173 and the second surface 174 may define the coupling space 175. The first surface 173 of the air guide 170 may be seated on the upper surface 171 of the discharge guide 150.

The discharge guide 150 includes an outer circumferential surface 152. When the movable part 730 descends, the diameter of the outer circumferential surface 152 of the discharge guide 150 is the diameter of the air guide 170 so that the cleaning part 740 smoothly descends without interference with the discharge guide 150. It may be formed smaller than the diameter of the contact surface 175 (diameter difference is D1).

In addition, the discharge guide 150 is tapered when the cleaning surface 741 of the cleaning part 740 smoothly descends from the contact surface 175 of the air guide 170. 153) may be further included. The tapered surface 153 is an inclined surface connecting the upper surface 151 and the outer peripheral surface 152 of the discharge guide 150. The tapered surface 153 may be inclined such that the outer circumferential surface of the discharge guide 150 decreases toward the upper side.

At this time, the minimum diameter of the outer circumferential surface 152 in the discharge guide 150 and the diameter of the contact surface 175 of the air guide 170 differ by D2. That is, the upper end of the outer circumferential surface of the discharge guide 170 is recessed inward, and the upper end of the recess is maximum.

Accordingly, when the cleaning surface 741 of the cleaning unit 740 deviates from the contact surface 175 of the air guide 170, the cleaning surface 741 is brought back to the tapered surface 153 by an elastic restoring force. You can return. At this time, the cleaning surface 741 of the cleaning unit 740 may contact at least one point of the tapered surface 153.

At this time, the diameter of the cleaning surface 741 of the cleaning unit 740 is formed smaller than the maximum diameter of the outer circumferential surface 152 of the discharge guide 150.

Thus, when the cleaning surface 741 is positioned on the tapered surface 153, and the cleaning unit 740 is continuously lowered, the cleaning surface 741 is again the outer peripheral surface 152 of the discharge guide 150 ) Is elastically deformed outward in the radial direction, and descends while in contact with the outer circumferential surface 152 of the discharge guide 150 in an elastically deformed state.

17 is an enlarged view of part B of FIG. 15.

15 to 17, the discharge guide 150 may further include a seating surface 156 on which the air guide 170 is seated.

At this time, the sealing member 179 is coupled to the lower surface of the air guide 170, the sealing member 179 may be seated on the seating surface 156.

The inner circumferential surface of the discharge guide 150 is formed in multiple stages, and may include a first inner circumferential surface 157 and a second inner circumferential surface 158.

At this time, the diameter of the first inner peripheral surface 157 is smaller than the diameter of the second inner peripheral surface 158. Of course, it is also possible that the inner circumferential surface of the discharge guide 150 is composed of one inner circumferential surface of a single diameter.

When the air guide 170 is seated on the discharge guide 150, the second surface 174 of the air guide 170 may face the first inner peripheral surface 157 of the discharge guide 150.

In consideration of assembly tolerances when the discharge guide 150 and the air guide 170 are combined, the diameter of the first inner circumferential surface 157 is larger than the diameter of the second surface 174 of the air guide 170 do.

At this time, the diameter of the first inner circumferential surface 157 of the discharge guide 150 is greater than the difference D2 between the minimum diameter of the outer circumferential surface 152 and the contact surface of the air guide 170 in the discharge guide 150. The diameter difference D3 of the second surface 174 of the air guide 170 may be designed to be small.

Although not limited, D3 may be formed to be 1.7 times or more of D2.

When a portion of the first inner circumferential surface 157 of the discharge guide 150 is close enough to contact the second surface 174 of the air guide 170 due to an assembly error, the discharge guide is provided at the opposite side of the corresponding part The difference between the diameter of the first inner circumferential surface 157 of 150 and the diameter of the second surface 174 of the air guide 170 may be greater than D3.

Even if the difference in diameter between the diameter of the first inner peripheral surface 157 of the discharge guide 150 and the second surface 174 of the air guide 170 is increased, D2 is designed to be larger than D3, so that the discharge guide ( In 150), a phenomenon in which the portion having the smallest diameter on the outer circumferential surface 152 is protruded outward in the radial direction than the contact surface 1754 of the air guide 170 may be prevented.

18 is an enlarged view of part C of FIG. 15.

Referring to FIG. 18, the lower side of the discharge guide 150 is formed in a cylindrical shape, and a part is accommodated in the filter unit 130 in a cylindrical shape.

The discharge guide 150 may include an insertion part 158 inserted into the filter part 130. In order for the insertion portion 158 to be inserted into the filter portion 130, the diameter of the outer circumferential surface 158a of the insertion portion 158 may be smaller than the inner diameter of the filter portion 130.

In the state where the insertion portion 158 of the discharge guide 150 is inserted into the filter portion 130, a portion of the discharge guide 150 is seated on the upper surface of the filter portion 130.

The outer diameter of the filter unit 130 so that the cleaning surface 741 of the cleaning unit 740 contacting the outer circumferential surface 152 with the discharge guide 150 may smoothly descend toward the filter unit 130 in a descending process. May be formed smaller than the diameter of the outer circumferential surface 152 of the discharge guide 150.

Therefore, the cleaning surface 741 of the cleaning unit 740 may be smoothly moved from the outer circumferential surface 152 of the discharge guide 150 to the outer surface of the filter unit 130.

As described above, the outer diameter of the filter unit 130 is larger than the diameter of the cleaning surface 741.

19 is a cross-sectional view showing a state in which the lower side of the filter part of the present invention is seated on a dust guide.

4 and 19, the dust guide 160 is formed on a storage wall 161 forming the second dust storage unit 122 and an upper side of the storage wall 161. 2 may include a support portion 164 for supporting the cyclone portion 130.

The storage wall 161 is formed in a column shape having a circular cross-section, and may be formed such that the diameter of the first dust storage unit 120 decreases as it goes from the top to the bottom.

The dust guide 160 may further include a scattering prevention rib 162 extending downward from the upper end of the storage wall 161.

The shatterproof rib 162 may be formed in a cylindrical shape, for example, and may surround an upper portion of the storage wall 161 in a state spaced apart from the storage wall 161.

Since the diameter of the storage wall 161 decreases toward the lower side, a space is formed between the outer circumferential surface of the storage wall 161 and the scattering prevention rib 162.

The cyclone flow may descend while flowing along the inner circumferential surface of the first body 10. When the cyclone flow reaches the body cover 114 in the process of descending the cyclone flow, the rotational flow may be changed back to an upward flow.

If there is an upward flow in the first dust storage unit 120, there is a problem that the dust stored in the first dust storage unit 120 is scattered.

In the present embodiment, the upward flow in the first dust storage unit 120 is changed back to the downward flow by the shatterproof rib 162 in the space between the shatterproof rib 162 and the storage wall 161. . Accordingly, scattering of the dust stored in the first dust storage unit 120 is prevented, and accordingly, a problem of backflow of dust to the second cyclone unit 140 may be prevented.

Since the scattering prevention ribs 162 extend downward from the upper end of the storage wall 161, dust separated from the first cyclone portion 110 along with the cyclone flow is applied to the scattering prevention ribs 162. By this, it can be smoothly moved to the first dust storage unit 120.

Meanwhile, the support part 164 may include an insertion part 165 inserted under the filter part 130. When the insertion portion 165 of the support portion 164 is inserted under the filter portion 130, the lower end of the filter portion 130 is supported around the insertion portion 165 in the support portion 164 It rests on the face 166.

In the state in which the filter unit 130 is seated on the support surface 166, the cleaning unit 740 descends and passes through the filter unit 130.

The diameter of the outer circumferential surface 167 of the support portion 164 decreases toward the lower side so that the outer circumferential surface 167 of the support portion 164 is prevented from interfering with the cleaning portion 740 while the cleaning portion 740 descends Can be formed. That is, the outer circumferential surface 167 of the support portion 164 may be inwardly inclined toward the lower side.

In addition, the maximum diameter of the outer circumferential surface of the support part 164 may be the same as or smaller than the diameter of the outer circumferential surface of the filter part 130.

In addition, in the process of descending the movable part 730, the author's dust is compressed in the first dust storage unit 120. When the outer circumferential surface 167 of the support part 164 is inclined inward, the compressed dust is easily descended. There is an advantage to do.

The scattering prevention ribs 162 may extend downward from the boundary between the support part 164 and the storage wall 161. The outer circumferential surface of the shatterproof rib 162 may be inclined to form a continuous surface with the outer circumferential surface 167 of the support 164. That is, the outer diameter of the outer circumferential surface of the shatterproof rib 162 may decrease toward the lower side.

20 is a cross-sectional view taken along line D-D of FIG. 1, FIG. 21 is a cross-sectional view taken along line E-E of FIG. 1, and FIG. 22 is a cross-sectional view taken along line F-F of FIG.

1, 20 to 22, the operation unit 710, the first portion 711 located inside the handle portion 3, and the first portion 711 extends in the horizontal direction , It may include a second portion 713 located on the outside of the handle portion (3).

Since the second part 713 is located outside the handle part 3, the user can press the upper surface of the second part 713. Therefore, the second portion 713 in the operation unit 710 may be referred to as a pressing unit.

The first portion 711 may include a first side portion 711a facing the outer circumferential surface of the second body 20 and formed with a curvature substantially equal to the curvature of the outer circumferential surface of the second body 20. have.

A guide rib 190 for guiding a part of the first portion 711 may be provided on the second body 20. The guide rib 190 protrudes from the outer circumferential surface of the second body 20 and may extend in the vertical direction.

The guide rib 190 may be rounded in the horizontal direction so that the first portion 711 can be stably moved up and down. Accordingly, the first portion 711 may further include a second side portion 711b that is rounded with a curvature substantially equal to the curvature of the guide rib 190.

In this embodiment, the first side portion 711a of the first portion 711 may contact the second body 20, and the second side portion 711b of the first portion 711 may be the guide rib (190).

When the manipulation unit 710 descends while a plurality of points of the first part 711 come into contact with the surrounding structure, a phenomenon in which the manipulation unit 710 inclines in the left-right direction during the descending process is prevented, so that the manipulation unit ( A stable descent of 710) is possible (the same is true for ascent).

The transmission unit 720 is connected to the first portion 711. A fitting groove 712 in which a part of the transmission part 720 is fitted is formed in the first part 711.

In the process of manipulating the operation unit 710, the horizontal portion of the portion 724 inserted into the fitting groove 712 in the transmission unit 720 to prevent relative rotation of the transmission unit 720 and the operation unit 710 The cross section can be formed in a non-circular shape.

Therefore, a cross-sectional view of the fitting groove 712 may be formed in a non-circular shape. The fitting groove 712 may be formed as the lower surface of the first portion 711 is recessed upward.

The operation unit 710 may further include a neck portion 714 provided between the first portion 711 and the second portion 713.

The neck portion 714 is formed to have a width narrower than the horizontal width of the first portion 711 and the second portion 713. The neck portion 714 may be located in the slot 310 of the handle portion 3.

The handle body 30 may include a guide end 714 contacting the neck 714 while the neck 714 is positioned in the slot 310.

One side of the neck 714 may contact the outer circumferential surface of the second body 20, and the other side may contact the guide end 311. The guide end 311 may make a surface contact with the neck 714.

As described above, when the guide end 311 contacts the neck portion 714 of the operation portion 710, the operation portion 710 is tilted in the left-right direction and rotated in the horizontal direction during the descending process of the operation portion 710. The phenomenon is prevented, and a stable descent of the operation unit 710 is possible (the same applies to the case of ascent).

Since the user has to press the second part 713, the horizontal width of the second part 713 may be formed to be larger than the horizontal width of the first part 711.

In addition, the second portion 713 is based on the neck portion 714 so that a space for pressing the second portion 713 at a boundary between the second body 20 and the handle body 30 is secured. As it may be bent in a form away from the outer peripheral surface of the second body (20).

Therefore, the second portion 713 may be spaced apart from the outer circumferential surface of the second body 20. That is, the second portion 713 includes a side portion rounded in a direction away from the outer circumferential surface of the second body 20.

As the second portion 713 is bent in a form away from the outer circumferential surface of the second body 20, when the operation portion 710 descends, the second portion 713 points to the slot 310 While descending, it may be minimized that the inner structure of the handle part 3 is exposed to the outside through the slot 310.

Referring to FIG. 20, an imaginary line A2 extending in a tangential direction with respect to an outer circumferential surface of the second body 20 and passing through the transmission unit 720 passes through the second portion 713 or the second portion It may be arranged to overlap with (713) in the vertical direction.

Then, in the state in which the handle portion 3 is held with the right hand, the second portion 713 of the operation portion 710 is located on the left side of the handle portion 3, and the second portion 713 is the handle portion. The second portion 713 is bent at the neck 714 so as to be located close to (3). Therefore, there is an advantage that the user can easily check and operate the second part 713 of the operation unit 710.

An elastic member 790 for elastically supporting the operation unit 710 may be supported on the guide rib 190 in a state where the cleaning mechanism 70 is positioned in a standby position.

When the elastic member 790 supports the operation unit 710, the cleaning mechanism 70 may be prevented from unintentionally descending due to the load of the cleaning mechanism 70.

Specifically, the elastic member 790, the first elastic body 792 and a support body (extended in a bent form at the top of the first elastic body 792) supporting the lower side of the operation unit 710 ( 794) and a second elastic body 796 extending from the top of the support body 794.

The first elastic body 792 extends in the vertical direction and a part of the lower elastic body is bent to extend in the horizontal direction. That is, the first elastic body 792 may be formed, for example, in the form of "L".

Therefore, the first elastic body 792 may include a vertical extension 792a and a horizontal extension 792b.

The vertical extension portion 792a may contact the guide rib 190.

The support rib 191 may extend in the horizontal direction from the guide rib 190. In addition, a horizontal extension 792b of the first elastic body 792 may be seated on the support rib 191.

A fixing rib 192 may be provided on the outer circumferential surface of the second body 20 so that the position of the first elastic body 792 is fixed. The fixed rib 192 may be formed, for example, in the form of "L".

The fixed rib 192 may include a vertical rib 192a extending in the vertical direction and a horizontal rib 192b extending in the horizontal direction from the bottom of the vertical rib 192a.

The vertical extension portion 792a may be positioned between the vertical rib 192a and the guide rib 190. In addition, the horizontal extension 792b may be positioned between the support rib 191 and the horizontal rib 192b.

The vertical extension portion 792a contacts the vertical rib 192a and the guide rib 190 so that the vertical movement and horizontal movement of the first elastic body 792 are limited, and the horizontal extension portion 793 Is in contact with the support rib 191 and the horizontal rib (192b).

The vertical rib 192a may be shorter in length than the vertical length in the vertical extension 792a so that a portion of the vertical extension 792a is elastically deformed.

Accordingly, the vertical rib 192a may contact only a portion of the vertical extension portion 792a, and a portion of the vertical rib 192a that does not contact the vertical extension portion 792a may be elastically deformed.

An inclined surface 192c is formed on the upper surface of the vertical rib 192a so that the vertical extension 792a is prevented from being damaged by the vertical rib 192a in the process of elastic deformation of the vertical rib 192a. Can be.

The inclined surface 192c may be formed to incline downward from the upper end of the vertical rib 192a toward the vertical extension portion 792a.

The support body 794 includes a first inclined portion 794a inclined upward in a direction closer to the transfer portion 720 from the upper end of the vertical extension portion 792, and the first inclined portion 794a. A second inclined portion 794b that is inclined upward in a direction away from the transmission portion 720 from the top may be included.

A slot 194 for the support body 794 to pass through may be formed in the guide rib 190.

The transmission unit 720 is disposed spaced apart from the guide rib 190 in the horizontal direction, the support body 794 penetrates through the slot 194, the guide rib 190 and the transmission unit 720 Is located between. In addition, the support body 794 supports the lower surface of the first portion 711 of the operation unit 710.

The horizontal length of the first inclined portion 794a and the second inclined portion 794b is such that the support body 794 supports the lower surface of the first portion 711 of the manipulation portion 710. It may be formed to be longer than the horizontal length of the slot 194.

The first inclined portion 794a and the second inclined portion so that the support body 784 is prevented from contacting the transmission portion 720 in a state where the first portion 711 of the operation portion 710 is supported. The length of the portion 794b in the horizontal direction may be shorter than the horizontal distance between the vertical extension portion 792a and the transmission portion 720.

Therefore, the lower surface of the first portion 711 of the operation portion 710 substantially contacts the second inclined portion 794b.

The support body 794 is elastically deformed by the load of the cleaning mechanism 70 while the lower surface of the first portion 711 of the operation portion 710 contacts the second inclined portion 794b, and the cleaning is performed. In order to prevent the mechanism 70 from being struck downward, the slot 194 includes a first inclined surface 194a that the first inclined portion 794a contacts and a second inclined portion 794b that is in contact with. 2 may include an inclined surface 194b.

The second elastic body 796 may extend vertically from an upper end of the second inclined portion 794b. The second elastic body 796 contacts the guide rib 190 to prevent the support body 794 from being excessively deformed, and the first inclined portion 794a and the second inclined portion 794b ) To keep the inclination angle constant.

In the elastic member 790, the support body 794 is located on the vertical movement path of the operation unit 710.

Therefore, the elastic member 790 provides elastic force to the manipulation unit 710 before manipulating the manipulation unit 710. In addition, after the manipulation unit 710 is operated and the manipulation member 710 presses the elastic member 790 to deform the elastic member 790, the elastic member 790 is resilient to the manipulation unit 710. Does not provide

In order to deform the elastic member 790 at an initial stage of operation of the manipulation unit 710, a force greater than the elastic force of the elastic member 790 is applied, and after the elastic member 790 is deformed, the elastic member 790 Since the control unit 710 is pressed in a state in which the elastic force of the controller is not received, there is an advantage of reducing the force applied to the control unit 710.

That is, since the elastic member 790 does not continuously provide elastic force to the manipulation unit 710 in the process of the operation unit 710 descending, there is an advantage that the force for manipulating the manipulation unit 710 can be reduced.

Meanwhile, as described above, the guide body 180 may be formed outside the first body 10.

The guide body 180 protrudes from the outer circumferential surface of the first body 10, and the upper side wall 181 of the guide body 180 may overlap the transmission part 720 in the vertical direction.

Therefore, the transmission unit 720 may penetrate the upper wall 181 of the guide body 181. The upper wall 181 of the guide body 181 is a substantially horizontal surface, and an opening 182 through which the transmission part 720 can pass may be formed.

That is, the transmission unit 720 may penetrate the opening 182 in the vertical direction, and may be moved in the vertical direction even in the state through the opening 182.

According to the present exemplary embodiment, the size of the opening 182 that provides a passage for the transmission unit 720 to move as well as the transmission unit 720 can be minimized, and thus the first body Air and dust in (10) can be prevented from leaking out through the opening (182).

A portion of the opening 182 may be partially lowered so that the transfer portion 720 can be smoothly moved in the vertical direction while the transfer portion 720 penetrates the upper wall 181 of the guide body 180. It is formed to increase in diameter as it goes toward. That is, the opening 182 has a lower inclined surface 183.

Therefore, in the state located in the opening 182, the transmission unit 720 contacts some of the circumferential surfaces of the opening 182 and does not contact other parts.

The contact area between the circumferential surface of the transmission unit 720 and the opening 182 is reduced, thereby reducing frictional force between the circumferential surface of the opening 182 and the transmission unit 720 so that the transmission unit 720 can move up and down smoothly. Can be.

In the frame 760, the coupling part 764 to which the transmission part 720 is coupled may be positioned directly below the opening 182. That is, the transmission part 720 passing through the opening 182 may be coupled to the coupling part 764.

The diameter of the coupling portion 764 may be formed larger than the diameter of the opening 182.

Then, in the standby position, the coupling portion 764 may contact the lower surface of the upper wall 181. Therefore, the engagement portion 764 shields the opening 182 in the standby position.

Therefore, it is possible to effectively prevent air and dust in the first body 10 from leaking through the opening 182 while the movable part 730 is located in the standby position.

In the present exemplary embodiment, the cleaning mechanism 70 may descend when a user operates the manipulation unit 710 in one direction, and when the cleaning mechanism 70 moves to a descending position, the user may operate the manipulation unit 710. Can be lifted in the other direction to return to the standby position.

In this embodiment, there is no return means for returning the cleaning mechanism 70 from the lowered position to the standby position in the cleaner 1.

The returning means prevents the cleaning mechanism 70 from descending due to its own weight when the cleaning mechanism 70 is located in the standby position.

However, in this embodiment, even if such a return means does not exist, the cleaning mechanism 70 may not be lowered by its own weight at the standby position.

This is because the cleaning mechanism 70 is supported in three parts at the standby position of the cleaning mechanism 70.

First, the first portion 711 of the operation unit 710 is supported by the elastic member 780, so that the descent due to the self-weight of the cleaning mechanism 70 may be limited. As described above, the elastic member 780 does not provide elastic force to the manipulation unit 710 in a section other than the initial section among the descending sections of the manipulation unit 710.

Second, the lowering due to the self-weight of the cleaning mechanism 70 may be limited by the frictional force between the transmission unit 720 and the circumferential surface of the opening 182. That is, since the transmission part 720 is in contact with the circumferential surface of the opening 182, the frictional force between the transmission part 720 and the circumferential surface of the opening 182 acts as a supporting force of the cleaning mechanism 70. do.

Third, the drop due to the self-weight of the cleaning mechanism 70 may be limited by the contact friction between the contact surface 175 of the air guide 170 and the cleaning surface 741 of the cleaning unit 740.

Since the return means for returning the cleaning mechanism 70 is unnecessary by the three structures as in the present invention, the structure for forming and arranging the return means can be omitted, and the structure is simplified.

In addition, a phenomenon that the cleaning mechanism 70 may not move smoothly may be eliminated because dust is caught in the return means and the return means does not operate smoothly.

23 is a cross-sectional view taken along line GG of FIG. 3, FIG. 24 is a perspective view showing the inner structure of the first body according to an embodiment of the present invention, and FIG. 25 is a first body according to an embodiment of the present invention It is a perspective view showing the guide body.

23 to 25, the guide body 180 is a structure formed as a part of the first body 10 is recessed outward, and the guide body 180 includes the transfer part 720 and A moving space 188 for moving the coupling portion 764 is provided.

For example, the guide body 180 may have a shape of rounding to convex outward from the first body 10. That is, the horizontal cross-section of the guide body 180 may be formed in a semi-circular shape.

The moving space 188 communicates with the inner space of the first body 10. The inner space of the first body 10 and the moving space 188 of the guide rib 180 are communicated by a communication hole.

The communication hole may include an upper hole 185 and a lower hole 186 extending downward from the upper hole 185 and having a width greater than the width of the upper hole 185.

The reason why the width of the lower hole 186 is formed larger than the width of the upper hole 185 is that the coupling portion 764 of the movable part 730 is moved to the moving space 188 through the lower hole 186. This is for easy entry. Therefore, the assembly of the movable part 730 may be improved.

For example, the width W1 of the lower hole 186 may be formed larger than the diameter of the coupling portion 764.

In addition, the outer peripheral surface of the engaging portion 764 may be spaced apart from the inner peripheral surface of the guide body 180 while the engaging portion 764 passes through the lower hole 186. This is to prevent friction between the inner circumferential surfaces of the coupling part 764 and the guide body 180 during the process of lifting and lowering the cleaning mechanism 70.

A pair of ribs 187 spaced apart in the horizontal direction may be provided in the first body 10. Substantially, the pair of ribs 187 define the upper hole 185. That is, the upper hole 185 is positioned between the pair of ribs 187.

A pair of ribs 187 are formed in a portion corresponding to the upper space among the moving spaces of the first body 10 so that the width of the upper hole 185 is reduced.

The gap between the pair of ribs 187, that is, the width of the upper hole 185 is smaller than the diameter of the coupling portion 764, and is larger than the horizontal width of the extension portion 763 of the frame 760. Can be.

Therefore, when the cyclone flow is turned on the upper side of the first body 10, it can be minimized that dust is introduced into the moving space 188.

The lower wall 188 of the guide body 180 is positioned at a predetermined height from the lower end of the first body 10, and a lower opening 189 may be formed in the lower wall 188.

The lower opening 189, in the assembly process, the movable portion 730 is located in the first body 710, the engaging portion 764 in the state in the guide body 180, the engaging portion A tool for fastening the 764 and the transmission unit 720 may provide a path through which the tool can move.

Therefore, the sealing member 80 may be coupled to the lower opening 189 to prevent air leakage after completion of assembly. For example, the sealing member 80 may include an insertion portion 81 that is inserted into the space in the guide body 180 through the lower opening 189.

In addition, the sealing member 80 may further include a stopper 82 having a larger horizontal cross-sectional area than the insertion portion 81 to limit the insertion depth of the insertion portion 81.

The sealing member 81 may be formed of, for example, a rubber material, so that the sealing member 80 is inserted by fitting the insertion portion 81 into the guide body 180 even without a separate coupling means. It may be coupled to the guide body 180.

The upper surface of the sealing member 80 may be inclined downward toward the center of the first body 10. That is, the sealing member 80 may include an inclined surface 83.

The lowest point of the inclined surface 83 is located closest to the lower hole 186 and may be higher than the lowest point 186a of the lower hole 186.

Since the moving space 188 in the guide body 180 communicates with the space inside the first body 10, the dust in the first body 10 in the cleaning process using the cleaner 1 is the moving space ( 188).

The dust moved to the moving space 188 falls to the upper surface of the sealing member 80. At this time, since the upper surface of the sealing member 80 is an inclined surface 83, dust dropped on the inclined surface 83 of the sealing member 80 can be smoothly drawn into the first body 10.

Even if dust is accumulated on the inclined surface of the sealing member 80, the engaging portion 764 presses the dust located on the inclined surface 83 downward in the course of the operation of the cleaning mechanism 70. Therefore, dust on the inclined surface 83 may be introduced into the first body 10 along the inclined surface 83.

26 is a cross-sectional view taken along line H-H of FIG. 3, and FIG. 27 is a cross-sectional view taken along line I-I of FIG. 3.

4, 26 and 27, in the state in which the suction part 5 is coupled to the main body 2, the longitudinal axis A5 of the suction part 5 is tangent to the main body 2 Does not extend in the direction.

In order for cyclone flow to occur in the body 2, the air must flow in a tangential direction to the first body 10 and flow along the inner circumferential surface 101 of the first body 10.

Therefore, an inflow guide 52 may be provided in the suction part 5 to guide air flowing through the suction part 5 into the first body 10 in a tangential direction.

Therefore, the air flowing along the suction part 5 is diverted to the first body 10 by being diverted by the inflow guide 52.

In this embodiment, at least a part of the movable part 730 is disposed to face the suction part 5 while the cleaning mechanism 70 is moved to the standby position. That is, at least a part of the movable part 730 based on the bottom of the main body 2 is positioned at the same height as the suction part 5.

It is preferable that the movable part 730 is disposed at a position not facing the suction part 5, but in this case, the height of the body 2 is increased, which is not preferable.

The movable part 730 cleans the filter part 730 while being located in a space between the outer circumferential surface of the filter part 730 and the inner circumferential surface 101 of the first body 10.

Therefore, the outer circumferential surface of the movable part 730 is positioned adjacent to the inner circumferential surface 101 of the first body 10.

When the movable part 730 is located on a path that is drawn from the suction part 5 to the first body 10, the flow performance is deteriorated because the movable part 730 acts as a flow resistance.

Therefore, in the present embodiment, the first portion 10 of the movable portion 730 is as described above, so that the movable portion 730 acts as a flow resistance of air flowing into the first body 10 is minimized. A depression 767 may be formed to increase the space between the inner circumferential surface 101 and the outer circumferential surface of the movable portion 730.

Specifically, among the movable portion 730, the first extension line A3 of the inflow guide 52 and the second extension line parallel to the first extension line A3 and extending in the tangential direction of the first body 10 The depression 767 may be located at a portion positioned between (A4). At this time, the first extension line A3 is positioned between the second extension line A4 and the center of the first body 10.

Accordingly, a space between the outer circumferential surface of the movable part 730 and the inner circumferential surface 101 of the first body 10 may be increased by the depth of the dent of the recessed part 767. Therefore, air introduced into the first body 10 through the suction part 5 may be prevented from directly colliding with the movable part 730. The movable part 730 includes at least two parts having different diameters (or radii) by the recessed part 767.

The frame guide 765 is positioned on the first extension line A3 or the frame guide 765 is extended so that the frame guide 765 continuously guides air flowing along the inflow guide 52. The direction may be parallel to the first extension line A3.

Meanwhile, since the movable part 730 should be located in a space between the filter part 130 and the inner circumferential surface 101 of the first body 10 in the first body 10, the size of the first body 10 It should be possible to move the movable part 730 without increasing.

Therefore, in this embodiment, the movable part 730 is located inside the radial direction of the inner peripheral surface 101, which is the surface on which the cyclone flow is formed in the first body 10, and the transfer part 720 is the first 1 is located on the radially outer side of the inner peripheral surface 101, which is the surface on which the cyclone flow is formed in the body 10. In addition, the transmission unit 720 is connected to the movable unit 730 by an extension 763 of the frame 760 and the coupling unit 764.

That is, the transfer part 720 is located radially outside the inner circumferential surface where the cyclone flow is formed in the first cyclone part 110 and radially outside the inner circumferential surface of the dust container 112.

Therefore, in the process of transferring the operation force of the operation unit 710 to the movable unit 730, the transmission unit 720 is prevented from being interfered with the structure inside the first body 10. You can.

28 is a view showing a position of the cleaning mechanism and the filter unit in a state in which the cleaning mechanism according to an embodiment of the present invention is lowered, and FIG. 29 is a view showing a state in which the cleaning mechanism of the present invention descends and compresses dust in the dust container. to be.

4, 5, 28, and 29, in a state in which the cleaning mechanism 70 is moved to the standby position, the user can perform cleaning using the cleaner 1.

Air and dust sucked through the suction unit 5 by the operation of the suction motor 220 are separated from each other while flowing along the inner circumferential surface of the first cyclone unit 112.

The dust separated from the air flows downward and is stored in the first dust storage unit 121. The air separated from the dust flows to the second cyclone unit 140 after passing through the filter unit 130.

The dust separated from the air in the second cyclone unit 140 is discharged from the second cyclone unit 140 and then flows downward to be stored in the second dust storage unit 122. On the other hand, the air separated from the dust in the second cyclone unit 140 is discharged from the second cyclone unit 140 through the discharge guide 150.
