Abstract

A cleaner according to an aspect of the present specification comprises: a motor housing in which a motor for generating suction force for air suction is provided; a handle part which is coupled to the motor housing; a dust bin which is detachably coupled to the bottom side of the motor housing and in which suctioned dust is stored; a cyclone part which is disposed inside the dust bin and separates dust from air suctioned through an inlet portion; and a compression part which compresses dust in the dust bin, wherein the dust bin is separated downward from the motor housing so that a user can easily wash the dust bin.

Description

vacuum cleaner

The present specification relates to a vacuum cleaner, and more particularly, to a vacuum cleaner that can compress dust stored in the dust container and thus does not require frequent emptying of the dust container.

A vacuum cleaner is a household appliance that sucks in small garbage or dust and fills a dust bin by sucking air using electricity, and is generally called a vacuum cleaner.

Such a vacuum cleaner may be divided into a manual cleaner in which the user directly moves the cleaner to perform cleaning, and an automatic cleaner in which the user performs cleaning while driving by themselves.

In addition, the manual vacuum cleaner may be classified into a canister-type cleaner, an upright cleaner, a handy-type cleaner, a stick-type cleaner, and the like according to the shape of the cleaner.

Prior Document 1 (Korean Patent Application Laid-Open No. 10-2011-0106917) discloses a handheld vacuum cleaner.

The handheld vacuum cleaner includes a separation device that separates waste and dust from the airflow.

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

The centrifugal separator includes a first cyclone having a dust collector. A dust collector is disposed below the first cyclone, and the dust collector may be opened and closed by the base. The base is rotated by a hinge to open and close the dust collector.

A cover having a plurality of through holes and partially trapezoidal is positioned inside the first cyclone. A second cyclone is in communication with the first cyclone within the shroud.

In the case of this prior document 1, the air inside the first cyclone flows through the second cyclone after the air passes through the plurality of holes, and in the process of the air passing through the plurality of holes, dust forms the plurality of holes of the cover. will block

Therefore, the more the plurality of holes are clogged, the less the air flow is and the separation performance is deteriorated, so the user must periodically clean the cover.

In the case of Prior Document 1, after opening the dust collector by rotating the base, the user has to approach the cover side to clean the cover, so the cleaning of the cover is not easy.

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

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

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 frequently emptied in order to maintain the dust collection performance.

Prior Document 2 (Japanese Patent No. 3699679) discloses a technology capable of compressing dust in a dust collecting case.

The dust collecting case includes a dust separation chamber for separating dust from the air by centrifugal force, a dust accommodating chamber for accommodating dust introduced from the dust separation chamber, an intake cylinder positioned at the center of the dust separation chamber, and an outer side of the intake cylinder Includes filters that are

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 hairs are provided on an inner circumferential surface of the outer cylinder. A plurality of openings are formed in the outer cylinder so as not to obstruct the flow of air from the dust separation chamber into the intake cylinder.

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

Therefore, when the user manipulates the operation lever to lower the outer cylinder together with the compression plate, the brush hairs on the inner surface of the outer cylinder clean the filter on the outer periphery of the suction cylinder, and the compression plate compresses the dust stored in the dust accommodating chamber.

However, according to Prior Document 2, since the outer cylinder is configured to surround the entire intake cylinder in a state in which the operation lever is not 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 exist in the outer cylinder, the portion in which the openings are not formed acts as a flow resistance of the air, and thus there is a disadvantage in that the air flow performance is deteriorated.

In addition, since the outer cylinder is located on the outside of the intake cylinder, the dust in the dust separation chamber is in contact with the outer cylinder in a state in which the operation lever is not operated.

In addition, according to Prior Document 2, since the operation lever is located outside the separation chamber, in order for the operation lever to move up and down, a slot must be provided in the dust separation chamber in the vertical direction.

Since the operation lever does not cover the entire slot, there is a problem that air and dust inside the dust separation chamber leak to the outside through the slot.

In addition, in the case of Prior Document 2, since there is no structure for vertical movement without eccentricity in the process of vertical movement of the outer cylinder, there is a problem in that the vertical movement of the outer cylinder is not smoothly performed.

In addition, in the case of Prior Document 2, since the operation lever can be operated after the dust collection case is separated from the cleaner body, it is cumbersome to use.

And FIG. 4 is a perspective view of a main part of the dust container according to the first embodiment of the present specification, FIG. 5 is a cross-sectional view showing the coupling state of the dust container and the motor housing according to the first embodiment of the present specification, and FIG. 6 is the first embodiment of the present specification. It is a cross-sectional view showing a state in which the lower side of the filter unit is seated on the dust guide according to the first embodiment.

1 to 6 , the cleaner according to the first embodiment of the present invention may include a dust container 100 . The dust container 100 may include a pipe connector 110 through which air containing dust is sucked. The pipe connector 110 may guide air containing dust to the dust container 100 .

The cleaner may further include a motor housing 200 to which the dust container 100 is coupled to a lower side, and a handle unit 300 coupled to the motor housing 200 .

The handle part 300 may be positioned opposite to the pipe connector 110 in the motor housing 200 . However, the positions of the pipe connector 110 and the handle unit 300 are not limited thereto.

The dust container 100 may separate dust sucked inside through the pipe connector 110 and store the separated dust.

A dust separation unit may be positioned inside the dust container 100 . The dust separation unit may include a first cyclone unit 120 capable of separating dust by cyclone flow. The first cyclone part 120 may communicate with the pipe connector 110 .

Air and dust sucked in through the pipe connector 110 helically flow along the inner circumferential surface of the first cyclone part 120 .

The dust separation unit may further include a second cyclone unit 130 that separates dust from the air discharged from the first cyclone unit 120 .

The second cyclone unit 130 may include a plurality of cyclone bodies 131 arranged in parallel. Air may be divided into the plurality of cyclone bodies 131 and pass through.

As another example, the dust separation unit may have a single cyclone unit.

The dust container 100 and the motor housing 200 to which the dust container 100 is coupled to the lower portion may be formed in a cylindrical shape, for example.

The lower side of the dust container 100 may be opened and closed by a body cover that rotates by a hinge. However, the lower side of the dust container 100 may be formed as a single body with the dust container body.

The vacuum cleaner according to an embodiment of the present invention may include a filter unit for filtering dust discharged to the outside through the suction unit. The filter unit may include a main filter 140 disposed inside the dust container 100 to surround the second cyclone unit 130 .

The main filter 140 is formed in a cylindrical shape, for example, and guides the air separated from the dust in the first cyclone unit 120 to the second cyclone unit 130 . The main filter 140 filters dust while air passes through it.

To this end, the main filter 140 may include a mesh portion 141 having a plurality of holes. The mesh portion 141 is not limited, but may be formed of a metal material.

In general, the mesh portion 141 is manufactured by forming a fine hole in a plate of a thin metal material through a machine tool such as a press. This can happen. Such curling accelerates the winding of long hair or animal hair in the process of air passing through the mesh part during product use, and even if the compression part is operated, dirt may not be separated depending on the curling structure.

Accordingly, as a preferred embodiment of the present invention, after the formation of the mesh part, a post-operation of smoothing the periphery of each fine hole can be performed, and through this post-work, the burr formed around each hole is removed to the surface of the mesh filter. can be made smooth. Through this effect, when air passes through, hair or long-length dirt that is wound around the main filter 140 can be easily separated by the compressor.

Since the mesh unit 141 filters the air, dust may accumulate on the mesh unit 141 , and the mesh unit 141 needs to be cleaned.

Accordingly, in the present invention, the cleaner may further include a compression unit 150 for cleaning the main filter 140 , for example, a simple cleaning system.

The compression unit 150 includes a movable part 151 disposed in the motor housing 200 to be movable in the vertical direction inside the dust container 100, and a user's operation to move the movable part 151 in the vertical direction. It may include a manipulation unit 153 and a transmission unit 155 for transmitting the manipulation force of the manipulation unit 153 to the movable unit 151 .

The manipulation unit 153 may be disposed outside the motor housing 200 . For example, the manipulation unit 153 may be positioned higher than the motor 230 disposed inside the motor housing 200 . In addition, the manipulation unit 153 may be positioned higher than the movable unit 151 .

The transfer unit 155 is formed to be elongated in the vertical direction inside the motor housing 200 , the manipulation unit 153 is coupled to an upper end thereof, and the movable unit 151 is coupled to the lower end thereof.

In a state in which the manipulation unit 153 is not operated, the movable unit 151 is located above the main filter 140 , and when the manipulation unit 153 is operated, the movable unit 151 is the main filter 140 . It moves downward along the outer circumferential surface.

The handle unit 300 may include a handle body 310 for gripping by a user, and a battery housing 320 disposed below the handle body 310 and capable of accommodating the battery 330 . .

In a state in which the user grips the handle body 310 with the right hand, the manipulation unit 153 may be located on the left side of the handle body 310 .

Accordingly, the manipulation unit 153 can be easily operated with the left hand that does not grip the handle body 310 .

The manipulation unit 153 may be moved in a direction parallel to the axis of cyclone flow of the first cyclone unit 120 , for example, in a vertical direction while the dust container 100 is placed on the floor.

A slot 210 may be formed in the motor housing 200 to move the manipulation unit 153 . The slot 210 may also extend in a direction parallel to the extension direction of the axis of cyclone flow of the first cyclone unit 120 , that is, in the vertical direction.

However, it is also possible to form the slot 210 in the handle body 310 .

In the present embodiment, the extending direction of the axis of the cyclone flow is, for example, the vertical direction in the drawing, so that the “extending direction of the axis of the cyclone flow” described below may be understood to mean the “up and down direction”.

Referring to FIG. 2 , the diameter D1 of the motor housing 200 may be longer than the horizontal length L1 of the handle part 300 . In addition, the handle part 300 may be coupled to the motor housing 200 so that the left and right centers of the handle part 300 coincide with the center of the motor housing 200 .

The manipulation unit 153 may be located, for example, at a boundary where the motor housing 200 and the handle unit 300 contact each other.

Due to the difference between the diameter D1 of the motor housing 200 and the horizontal length L1 of the handle part 300 , the motor housing 200 and the handle part 300 both contact the floor F. When the vacuum cleaner is placed in such a manner that it is placed on the surface, a space is formed between the outer peripheral surface of the motor housing 200 and the outer peripheral surface of the handle part 300 and the floor F, and the manipulation unit 153 may be located in the space.

In this state, the manipulation unit 153 is spaced apart from the floor (F).

Accordingly, in the process of placing the cleaner on the floor (F), the manipulation unit 153 collides with the floor (F), thereby preventing the manipulation unit 153 from being damaged or the manipulation unit 153 being unintentionally manipulated. .

The transfer unit 155 may be formed in, for example, a circular bar shape, and the manipulation unit 153 may be coupled to an upper end of the transfer unit 155 . That is, the transfer unit 155 may have a circular horizontal cross section.

In addition, the transfer unit 155 may also extend in a direction parallel to the extension direction of the axis of cyclone flow of the first cyclone unit 120 .

Since the movable part 151 is located inside the motor housing 200 and the operation part 153 is located outside the motor housing 200, the movable part 151 and the operation part 153 are connected to each other. The transfer unit 155 may be located inside the motor housing 200 . That is, the manipulation unit 153 may pass through the motor housing 200 .

A compression rail 220 for guiding the vertical movement of the transmission unit 155 may be formed inside the motor housing 200 .

The compression rail 220 may extend in a direction parallel to an extension direction of an axis of cyclone flow of the first cyclone unit 120 .

Accordingly, the transfer unit 155 may move in the vertical direction within the compression rail unit 220 .

A motor 230 for generating a suction force may be disposed inside the motor housing 200 . Suction force generated by the motor 230 may act on the pipe connector 110 .

The motor 230 may be located above the dust container 100 and the battery 330 with respect to the extension direction of the cyclone flow axis of the first cyclone unit 120 . The manipulation unit 153 may be positioned at the same height as a part of the motor 230 or higher than the motor 230 .

An air guide 240 for guiding the air discharged from the second cyclone unit 130 to the motor 230 may be disposed inside the motor housing 200 .

The second cyclone unit 130 may be coupled to a lower side of the air guide 240 . The main filter 140 surrounds the second cyclone part 130 in a state coupled to the second cyclone part 130 .

Accordingly, the main filter 140 may also be positioned below the air guide 240 . The movable part 151 may be disposed at a position surrounding the air guide 240 in a state in which the operation part 153 is not operated.

The movable part 151 may include a compression plate for cleaning the main filter 140 .

In this embodiment, the position of the movable unit 151 in a state in which the operation unit 153 is not operated may be referred to as a standby position of the simple cleaning system.

In the standby position of the simple cleaning system, the movable part 151 may be disposed so as not to overlap the main filter 140 . Accordingly, air may pass through the main filter 140 .

For example, in the standby position, the movable part 151 may be positioned higher than the main filter 140 . Accordingly, in the standby position, it is possible to prevent the movable part 151 from acting as a flow resistance while the air passes through the main filter 140 .

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

The lower side of the dust guide 160 may be seated on the bottom surface of the dust container 100 . The dust guide 160 is spaced apart from the inner circumferential surface of the dust bin 100 to provide an inner space of the dust bin 100 with a first dust storage unit 161 for storing the dust separated from the first cyclone unit 120 . and a second dust storage unit 163 for storing the dust separated from the second cyclone unit 130 .

The inner peripheral surface of the dust container 100 and the outer peripheral surface 163b-3 of the dust guide 160 define the first dust storage unit 161 , and the inner peripheral surface of the dust guide 160 is the second dust storage unit (163) is defined.

When the body cover is provided, the lower side of the dust guide 160 may be seated on the body cover.

The compression plate constituting the movable part 151 may be formed of an elastically deformable material. For example, the compression plate may be formed of a rubber material. The compression plate may be formed in a ring shape so that the compression plate can clean the entire circumference of the cylindrical main filter 140 . As another example, the compression plate may be formed of a silicone or fiber material.

In addition, the compression plate waits at a position away from the main filter 140 in the standby position, and moves in the vertical direction while wiping the outer surface of the main filter 140 in the cleaning process.

The inner peripheral surface of the compression plate may include a cleaning surface in contact with the outer surface of the main filter 140 during the cleaning process. The cleaning surface is a surface facing the main filter 140 and may be a vertical surface.

Accordingly, when the compression plate descends while the entire cleaning surface is in contact with the circumference of the main filter 140 , the cleaning surface removes dust attached to the outer surface of the main filter 140 .

A diameter of the cleaning surface may be smaller than a diameter of the main filter 140 . In this embodiment, since the compression plate is formed of an elastically deformable material, the compression plate is elastically deformed radially outward of the main filter 140 while the compression plate descends and the cleaning surface contacts the main filter 140 . and the cleaning surface may be in contact with the main filter 140 in an elastically deformed state.

That is, in a state in which the cleaning surface is in contact with the main filter 140 , the cleaning surface may press the main filter 140 . As described above, since the cleaning surface cleans the main filter 140 in a state in which the main filter 140 is pressed, dust attached to the main filter 140 can be effectively removed from the main filter 140 .

In addition, since the entire circumference of the cleaning surface compresses the main filter 140 while the compression plate is made of an elastically changeable material, the center of the compression plate is inclined with respect to the axis of the cyclone flow in the process of descending the compression plate. Even though the cleaning surface of the compression plate maintains a state in which the main filter 140 is pressed, cleaning of the main filter 140 is possible.

The compression plate may include an inclined surface extending upwardly inclinedly outward from the cleaning surface in a radial direction.

Since the inclined surface is upwardly inclined outward, the inner diameter of the inclined surface portion of the compression plate increases toward the upper side. In addition, the inclined surface is spaced apart from the outer peripheral surface of the main filter 140 .

The movable part 151 may further include a frame supporting the outer periphery of the compression plate and a core portion supporting the inner periphery of the compression plate.

The core part may be in contact with a portion of an inner circumferential surface of the compression plate.

For example, the core part may be in contact with an inner inclined surface of the compression plate.

By forming a coupling protrusion on the compression plate, forming a coupling hole in the core part, and inserting the coupling protrusion into the coupling hole, the core part may be coupled to the compression plate.

The frame may support the compression plate and be coupled to the core to fix the position of the compression plate.

The transfer unit 155 may be formed in a cylindrical long bar shape. This is to enable smooth movement of the transfer unit 155 when the transfer unit 155 moves in the vertical direction inside the motor housing 200 .

In this embodiment, the compression plate may be integrally formed with the core part and the frame by double injection.

The dust guide 160 includes a storage wall 163a forming a second dust storage unit 163 , and a support portion formed above the storage wall 163a and supporting the second cyclone unit 130 . 163b).

The storage wall 163a may be formed in the form of a column having a circular horizontal cross section, and the diameter of the storage wall 163a may decrease from the upper side to the lower side so that the space of the first dust storage unit 161 is maximized.

The dust guide 160 may further include a scattering prevention rib 165 extending downward from the upper end of the storage wall 163a.

The scattering prevention rib 165 may be formed in a cylindrical shape, for example, and may surround an upper portion of the storage wall 163a while being spaced apart from the storage wall 163a.

Since the diameter of the storage wall 163a decreases toward the lower side, a space is formed between the outer circumferential surface of the storage wall 163a and the scattering prevention rib 165 .

The cyclone flow may descend while flowing along the inner circumferential surface of the dust container 100 . When the cyclone flow reaches the bottom surface of the body cover or the dust container 100 while the cyclone flow is descending, the rotational flow may be changed back to an upward flow.

If there is an upward flow in the first dust storage unit 161 , there is a problem in that the dust stored in the first dust storage unit 161 is scattered.

In this embodiment, the upward flow in the first dust storage unit 161 is changed to a downward flow again by the scattering prevention rib 165 in the space between the scattering prevention rib 165 and the storage wall 163a. .

Accordingly, the scattering of the dust stored in the first dust storage unit 161 is prevented, and accordingly, the problem of the dust from flowing backward toward the second cyclone unit 130 can be prevented.

Since the scattering prevention rib 165 extends downward from the upper end of the storage wall 163a, the dust separated from the first cyclone unit 120 along with the cyclone flow is disposed on the scattering prevention rib 165. Thus, it can be smoothly moved to the first dust storage unit 161 .

Meanwhile, the support part 163b may include an insertion part 163b - 1 inserted under the main filter 140 . When the insertion part 163b-1 of the support part 163b is inserted under the main filter 140, the lower end of the main filter 140 is the circumference of the insertion part 163b-1 in the support part 163b. It is seated on the support surface (163b-2) located in the.

In a state in which the main filter 140 is seated on the support surface 163b - 2 , the compression plate passes through the main filter 140 while descending.

In order to prevent the outer peripheral surface 163b-3 of the support part 163b from interfering with the compression plate in the process of the compression plate descending, the outer peripheral surface 163b-3 of the support part 163b decreases in diameter toward the lower side. can be formed. That is, the outer peripheral surface 163b - 3 of the support portion 163b may be inclined inward toward the lower side.

In addition, the maximum diameter of the outer circumferential surface 163b - 3 of the support portion 163b may be the same as or smaller than the outer circumferential diameter of the main filter 140 .

In addition, the dust stored in the first dust storage unit 161 is compressed during the descending process of the compression plate. There are advantages that can be

At the boundary between the support part 163b and the storage wall 163a, the scattering prevention rib 165 may extend downward. The outer circumferential surface of the shatterproof rib 165 may be inclined to form a continuous surface with the outer circumferential surface of the support portion 163b. That is, the outer diameter of the outer peripheral surface of the scattering prevention rib 165 may decrease toward the lower side.

Since the manipulation unit 153 is located outside the handle unit 300 , the user can press the upper surface of the manipulation unit 153 .

The manipulation unit 153 may include a first part positioned inside the motor housing 200 and a second part extending in a horizontal direction from the first part and positioned outside the motor housing 200 .

The transfer unit 155 is connected to the first part. A fitting groove into which a part of the transmission part 155 is fitted may be formed in the first part.

In the process of manipulating the manipulation unit 153 , a horizontal cross-section of a portion inserted into the fitting groove of the transmitting unit 155 is non-circular to prevent relative rotation between the transmitting unit 155 and the operating unit 153 . can be

Since the user must press the second part, the horizontal width of the second part may be greater than the horizontal width of the first part.

Although not specifically illustrated, an elastic member for elastically supporting the manipulation unit 153 may be supported on the compression rail unit 220 in a state where the compression unit 150 is positioned at a standby position.

The elastic member may not provide an elastic force to the manipulation unit 153 in a section other than the initial section of the descending section of the manipulation unit 153 .

Accordingly, when the elastic member supports the manipulation unit 153 , it is possible to prevent the compression unit 150 from being unintentionally lowered by the load of the compression unit 150 .

The elastic member may be formed in various shapes and structures.

Meanwhile, in the vacuum cleaner of the present specification, the compression rail 220 for guiding the vertical movement of the delivery unit 155 is not formed on the outside of the dust container 100 , and the delivery unit 155 is disposed inside the motor housing 200 . The vertical movement is guided only by the compression rail unit 220 located in the

Accordingly, since the outer diameter of the dust container 100 can be increased compared to the case where the compression rail unit is formed on the outer peripheral surface of the dust container 100 , the distance d1 between the inner peripheral surface of the dust container 100 and the second cyclone part 130 . can be sufficiently obtained.

For example, since it is possible to secure the distance d1 between the inner circumferential surface of the dust container 100 and the second cyclone unit 130 to 14 mm or more, it is possible to prevent large foreign substances such as cereal from being caught at the outlet side of the pipe connector 110 . can be effectively prevented.

In this embodiment, the movable part 151 can descend when the user manipulates the operation part 153 in one direction. It can be lifted in the direction and returned to the standby position.

In the present embodiment, the cleaner may not include a return means for returning the movable part 151 from the lowered position to the standby position, but it is also possible to include the return means.

The pipe connector 110 to which the suction part is coupled is coupled to the dust container 100 , and the dust container 100 provided with the pipe connector 110 is vertically detachably coupled to the motor housing 200 .

In order to detachably couple the dust container 100 and the motor housing 200 , coupling means may be formed in the dust container 100 and the motor housing 200 .

For example, referring to FIG. 4 , a screw portion 170 coupled to the motor housing 200 may be formed at an upper end of the dust container 100 .

However, it is also possible to form a coupling means having a different structure instead of the screw portion 170 .

In order to improve the sealing force between the dust container 100 and the motor housing 200 that are separably coupled in the vertical direction, a sealing material ( 180) may be located.

As described above, when the dust container 100 and the motor housing 200 are vertically separable, the sealing force between the dust container 100 and the motor housing 200 can be improved.

In the motor housing 200 adjacent to the pipe connector 110 , when the suction part is coupled to the pipe connector 110 , the electrical terminal part 250 is coupled to the terminal of the suction part to supply electricity to the suction part.

Conventionally, in which an electric wire and a terminal part through which electricity flows are connected to the cleaner body and the dust container, it is not easy to clean the dust container with water while using the vacuum cleaner. In particular, when the vacuum cleaner is operated in a dry state due to a consumer's mistake, there is a possibility that an electrical short circuit may occur, resulting in a safety problem.

However, in the vacuum cleaner according to the present specification, since the electric terminal unit 250 is installed in the motor housing 200, the dust bin containing no electrical components is separated from the motor housing and the dust bin can be cleaned with water according to the needs of the consumer. Also, the length of the motor/inverter wire can be reduced.

In addition, a structure for reinforcing the strength of the pipe connector 110 connected to the suction part, for example, a strength reinforcing lead, may be formed under the pipe connector 110 of the dust container 100 .

Hereinafter, a cleaner according to a second embodiment of the present specification will be described with reference to FIGS. 7 to 16 .

7 is an exploded perspective view of a cleaner according to a second embodiment of the present specification, and FIG. 8 is a view illustrating a coupling state between a dust container and a motor housing of the cleaner according to the second embodiment of the present specification.

9 to 16 are views illustrating a separation process of a dust container and a motor housing of a cleaner according to a second embodiment of the present invention.

In describing the cleaner according to the second embodiment, the same reference numerals are given to the same components as those of the cleaner of the first embodiment described above, and a detailed description thereof will be omitted.

The cleaner of the second embodiment is different from the cleaner of the first embodiment described above in that the pipe connector is fixedly coupled to the motor housing rather than the dust container and the dust container and the pipe connector are engaged/unlocked.

To explain this, in the cleaner of the present embodiment, the pipe connector 110 - 1 is fixedly coupled to the motor housing 200 rather than the dust container 100 .

In addition, the cleaner further includes a fastening part 400 for detachably coupling the dust container 100 to the motor housing 200 .

The fastening part 400 includes a button 410 positioned under the pipe connector 110 - 1 , and a hook 420 positioned in a space between the button 410 and the dust container 100 . The hook 420 described herein may be described as a front hook 420 or a first hook 420 to distinguish it from a hook 470 provided between the pull lever 460 and the dust container 100 to be described later. Also, the hook 470 provided between the pull lever 460 and the dust container 100 may be described as a rear hook 470 or a second hook 470 .

The hook 420 may be rotated clockwise by a pressing operation of the button 410 .

The fastening part 400 further includes a first locking protrusion 430 positioned on the outer surface of the dust container 100 .

The first stopping protrusion 430 is engaged with and/or released from the hook 420 according to whether the hook 420 is rotated.

The fastening part 400 further includes a second locking protrusion 440 located in a lower portion opposite to the first locking protrusion 430 among the outer surfaces of the dust container.

The second locking protrusion 440 is coupled to the groove 340 of the handle unit 300 .

The hook 420 comes in contact with the rib 411 and has a first inclined surface 421 for rotating the hook 420 in a clockwise direction, and extends from the first inclined surface 421 to rotate the hook 420 in a counterclockwise direction. and a second inclined surface 423 for rotation.

In FIG. 7 , unexplained reference numeral 510 denotes a HEPA filter, 520 denotes a prefilter, and 530 denotes a dust cap.

In an embodiment of the present invention, the filter unit may further include a HEPA filter 510 and a pre-filter 520 .

The HEPA filter 510 and the pre-filter 520 may be provided on the upper side of the motor housing 200 . Therefore, the air that has passed through the

cyclones

120 and 130 may be filtered again before being discharged to the outside of the cleaner 1 through the motor 230 .

Specifically, the HEPA filter 510 may be coupled to the upper side of the motor housing 200 to filter dust before the air that has passed through the motor 230 is discharged to the outside.

In addition, the pre-filter 520 may be disposed to surround at least a portion of the motor 230 , and may filter dust before the air that has passed through the

cyclones

120 and 130 is sucked into the motor 230 . In the embodiment of FIG. 7 , the pre-filter 520 may be provided to surround the circumferential surface of the motor 230 .

For example, the pre-filter 520 may be formed in a cylindrical shape to correspond to the shape of the motor, and the HEPA filter 510 is a disk having a predetermined height so as to be fitted and coupled to the upper side of the motor housing 200 . ) can be formed.

Accordingly, the air passing through the cyclone unit 120 may sequentially flow through the pre-filter 520 , the motor 230 , and the HEPA filter 510 and be discharged to the outside.

In addition, according to the fastening part 400 of the embodiment of FIG. 7 , the hook 420 and the first engaging protrusion 430 are maintained in a fastened state, and the second engaging protrusion 440 is the groove 340 of the handle part 300 . ), the dust container 100 is coupled to the motor housing 200 (see FIGS. 8 and 9 ).

In this state, when the button 410 is pushed in the opposite direction of the dust container 100 to separate the dust container 100 from the motor housing 200 , the rib 411 engages the first inclined surface 421 of the hook 420 . It is pressed in the downward direction, and thus the hook 420 is rotated clockwise to release the coupling between the hook 420 and the first stopping protrusion 430 (see FIG. 10 ).

And the clockwise rotation of the hook 420 is made until the rib 411 reaches the boundary point between the first inclined surface 421 and the second inclined surface 423 (see FIG. 11), the rib 411 The hook 420 starts to rotate in a counterclockwise direction from a point in time at which the first inclined surface 421 and the second inclined surface 423 pass through the boundary point and contact the second inclined surface 423 (see FIG. 12 ).

As described above, when the front part of the dust container 100 (the part facing the pipe connector) is pushed downward in a state in which the hook 420 and the first locking jaw 430 are released, the dust container 100 is moved to the second locking jaw. It is rotated slightly around 440 (see FIG. 13).

Thereafter, the second locking jaw 440 is separated from the groove 340 of the handle part 300 by slightly pushing the dust container 100 in the forward direction (see FIG. 14 ), and the rear part of the dust container 100 is moved downward again. to separate the dust container 100 from the motor housing 200 .

According to this process, the dust bin 100 is separated from the motor housing 200 and then the dust bin 100 is cleaned, and the cleaned dust bin 100 is re-coupled to the motor housing 200 in the reverse order of the above-mentioned process.

Meanwhile, in the motor housing 200 adjacent to the pipe connector 110-1, a terminal 250 for supplying electricity to the suction part when the suction part is coupled to the pipe connector 110-1 is located.

Hereinafter, a third embodiment of the present invention will be described with reference to FIGS. 17 to 28 .

17 is an external perspective view of the cleaner according to the third exemplary embodiment of the present specification as viewed from the rear, and FIG. 18 is a cross-sectional view illustrating a coupling state between the dust container and the motor housing of the cleaner according to the third exemplary embodiment of the present disclosure. Also, FIGS. 19 and 20 show the operation of the pull lever of the cleaner according to the third embodiment of the present specification, and FIGS. 21 and 22 show that the pull lever of the cleaner according to the third embodiment of the present specification operates. This is a diagram showing a state in which the coupling of the dust bin is released.

17 and 18 , the cleaner according to the third embodiment of the present invention may further include a pull lever 460 .

The pulling lever 460 may be provided on the dust container 100 side of the handle unit 300 . In addition, the position of the pull lever 460 may be provided on the upper side of the battery housing 320 in consideration of the user's gripping convenience. That is, the pull lever 460 may be provided in an empty space where the handle body 310 and the battery housing 320 are not disposed so that the user can easily grip it. Accordingly, the user may operate the pull lever 460 with the other hand while holding the handle body 310 with one hand.

17 to 20 , the pull lever 460 rotates around a grip part 461 , a shaft 462 , and a shaft 462 that can be gripped and pulled by a user to push the hook. and a separation arm 463 .

The grip part 461 is exposed to the outside of the cleaner, so that the user can intuitively recognize it and easily operate it.

The grip portion 461 may be recessed by a predetermined depth in order to increase the user's gripping convenience. As another example, it may be formed in a protruding bar shape, and may be provided by being deformed into various shapes that are easy for a user to grip.

In addition, the gripping part 461 may be provided toward the left when the pipe connector 110 or the electrical terminal part 250 is viewed from the handle body 310 . This is because, in consideration of the fact that users are generally right-handed, the gripper 461 can be more conveniently operated using the left hand while holding the handle body 310 with the right hand. . However, the present invention is not necessarily limited thereto, and for the same reason as described above, the left-handed user may be provided facing the right side for convenience or design convenience.

The separation arm 463 rotates when the user pulls the pull lever 460 and pushes the second hook 470 . Specifically, when the user rotates the grip part counterclockwise, it may rotate clockwise around the shaft 462 . Accordingly, the separation arm 463 pushes the extension 471 of the rear hook 470 toward the pipe connector 110 . (See Fig. 22)

Referring to FIGS. 21 and 22 , the rear hook 470 includes an extension 471 contacting the pull lever 460 and a locking part for fixing the position of the dust container 100 by engaging the third locking jaw 450 . 472 and an elastic part 473 provided with an elastic body.

The extension portion 471 and the locking portion 472 are connected to each other. A portion where the extension portion 471 and the locking part 472 are connected is formed in a shape corresponding to the end of the third locking projection 450 , so that the position of the third locking projection 450 may be stably fixed.

The extension part 471 rotates counterclockwise about the central axis of the elastic part 473 , and the locking part 472 connected to one end of the extension part 471 rotates together. (See FIG. 22 ) Accordingly, the end of the third locking jaw 450 having a fixed position by being caught by the locking part 472 is separated from the connected portion of the extension part 471 and the locking part 472 . In addition, since the coupling of the third locking jaw 450 is released, the dust container 100 may be naturally released in the direction of gravity from the fixed position.

A torsion spring may be selected as the elastic body provided in the elastic part 473 . Accordingly, the extension 471 receives an elastic restoring force to be restored to its original state in a state rotated by an external force. Accordingly, when the manipulation of the pull lever 460 by the user is finished, the rear hook 470 is restored to its original state.

23 illustrates a state in which the disengaged dust container is coupled to the motor housing in the cleaner according to the third embodiment of the present invention, and FIGS. 24 to 26 are the dust container in the cleaner according to the third embodiment of the present specification. The process of fastening to the rear hook is enlarged, and FIGS. 27 to 29 are enlarged views of the process in which the dust container is fastened to the front hook in the cleaner according to the third embodiment of the present specification.

Referring to FIG. 23 , the dust container 100 may be coupled to the dust housing 200 . In the third embodiment of the present invention, the dust container 100 may be coupled by pushing in a vertical direction with respect to the direction of gravity without a separate operation for the handle unit 300 .

In addition, in a normal state in which the rear hook 470 does not rotate, the locking part 472 may be provided to be inclined downward from the dust container 100 toward the handle body 310 .

The inclined angle of the third inclined surface 452 is formed more gently than the inclined angle of the engaging portion 472 with respect to the horizontal direction. Accordingly, when the dust container 100 is raised by the user while the third inclined surface 452 and the locking part 472 are in contact with each other, the locking part 472 is pushed toward the handle body 310 and the rear hook ( 470) may rotate counterclockwise.

Counterclockwise rotation of the rear hook 470 may occur until the end of the locking portion 472 deviates from the boundary of the third inclined surface 452 . (See FIG. 25 ) When the end of the locking part 472 deviates from the boundary of the third inclined surface 452 , there is no obstacle limiting the ascent of the dust container 100 above the third locking step 450 . Accordingly, the dust container 100 may be lifted up to a height at which it is coupled to the dust housing 200 by the user's force.

When the protrusion 451 of the third locking protrusion 450 rises to a height passing through the end of the locking part 472 , the pressing of the rear hook 470 counterclockwise is terminated. As described above, the elastic portion 473 of the rear hook 470 may include a torsion spring, and the rear hook 470 may be returned to its original state by the rotational restoring force of the torsion spring. That is, the rear hook 470 may rotate in a clockwise direction.

At the connection point of the locking part 472 and the extension part 471 , a groove recessed to a predetermined depth may be formed by a difference in angle. The protrusion 451 may be formed in a shape corresponding to the groove. Accordingly, in a state in which the rear hook 470 is returned to its original state, the protrusion 451 may be fastened to the groove, that is, a connection point between the locking part 472 and the extension part 471 . (See Fig. 26)

Referring to FIGS. 27 to 29 , the front hook 420 according to the third embodiment of the present invention may be moved by being pushed by the first stopping protrusion 430 . Specifically, the front hook 420 may be pushed and moved from the dust container 100 toward the pipe connector 110 by the first locking jaw 430 .

Referring to FIG. 27 , in the third embodiment of the present invention, the first locking protrusion 430 may be formed to protrude downward from the outer peripheral surface of the dust container 100 .

Specifically, the upper inclined surface 431 of the first stopping protrusion 430 may be formed to be inclined downward from the dust container 100 toward the pipe connector 110 . The upper inclined surface 431 may be in contact with the end of the front hook 420 . Accordingly, when the dust container 100 rises, the front hook 420 may be pushed and moved along the upper inclined surface 431 toward the pipe connector 110 . (See Fig. 28)

The fastening unit 400 may further include a link 425, which is a passage through which the front hook 420 is pushed, and an elastic body 424 provided in a space between the link 425 and the front hook 420. . (See Fig. 29)

When the user raises the dust container 100 upward in the direction of gravity, the front hook 420 and the first locking jaw 430 may contact each other. (See Fig. 27)

If the user continues to raise the dust container 100 while in contact with each other, the front hook 420 may be pushed forward along the slope of the upper inclined surface 431 . (See FIG. 28 ) The front hook 420 may move horizontally along the path of the link 425 . In this case, the elastic body 424 provided in the link 425 may be compressed by the front hook 420 . Accordingly, the elastic body 424 may generate a restoring force that pushes the front hook 420 toward the handle body 310 .

The front hook 420 may be pushed to a point where one end of the front hook 420 deviates from the boundary of the upper inclined surface 431 . When the end of the front hook 420 deviates from the boundary of the upper inclined surface 431 , there is no obstacle limiting the ascent of the dust container 100 above the first stopping protrusion 430 . Accordingly, the dust container 100 may be lifted up to a height at which it is coupled to the dust housing 200 by the user's force.

When the dust container 100 rises and the force pushing the front hook 420 toward the pipe connector 110 disappears, the front hook 420 moves toward the handle body 310 again by the restoring force of the elastic body 424 . can move At this time, the protrusion 432 of the first locking jaw 43 may be hooked into the groove formed in the front hook 420 to be fastened.
