Description

Vacuum cleaner

The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner capable of compressing dust stored in a dust box without frequent emptying of the dust box.

Generally speaking, a vacuum cleaner refers to an electrical appliance that uses electricity to suck in small garbage or dust by sucking in air and fill the dust box with the garbage or dust. Such vacuum cleaners are generally referred to as vacuum cleaners.

Vacuum cleaners may be classified into manual cleaners that are directly moved by a user to perform cleaning operations; and automatic cleaners that perform cleaning operations while traveling autonomously.

In addition, according to the shape of the vacuum cleaner, the manual vacuum cleaner can be divided into a cylinder vacuum cleaner, an upright vacuum cleaner, a hand-held vacuum cleaner, a stick vacuum cleaner, and the like.

Patent Document 1 (Korean Patent Application Publication No. 10-2011-0106917 ) discloses a hand-held vacuum cleaner.

The hand-held vacuum cleaner includes a separation device that separates litter and dust from the airflow.

The separation device includes a centrifugal separator with one or more cyclones.

The centrifugal separator includes a first cyclone with a dust collector. The dust collector may be disposed on the lower side of the first cyclone, and the dust collector may be opened or closed by the base. The base opens or closes the dust collector by rotating through a hinge.

A plurality of through holes are provided in the first cyclone, and a partially trapezoidal cover is located in the first cyclone. The second cyclone communicates with the first cyclone in the cover.

In the case of Patent Document 1, the air in the first cyclone passes through a plurality of through holes, and then flows into the second cyclone. During the process of air passing through the plurality of through holes, dust may block the plurality of through holes of the cover body.

Therefore, since the plurality of through holes are largely blocked, the air cannot flow smoothly, and the separation performance deteriorates. Therefore, the user needs to clean the cover regularly.

In the case of Patent Document 1, since the user needs to open the dust collector by rotating the base and then approach the cover to clean the cover, there is a disadvantage that it is not easy to clean the cover.

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

During the process of separating dust by the vacuum cleaner, when the vacuum cleaner stops operating, 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 an excessively large volume relative to its weight, there is a disadvantage that the dust in the dust collector must be frequently removed to maintain the dust collecting performance.

Patent Document 2 (Japanese Patent No. 3699679 ) discloses a technique capable of compressing dust in a dust collecting housing.

The dust collecting housing includes: a dust separation chamber configured to separate dust from the air using centrifugal force; a dust receiving chamber configured to receive dust introduced from the dust separation chamber; an air intake duct located at a central portion of the dust separation chamber; and a filter , set outside the intake manifold.

The air in this dust separation chamber passes through the filter and then enters the intake duct.

An outer container is arranged on the outside of the air intake cylinder, a compression plate is arranged on the lower side of the outer container, and bristles are arranged on the inner peripheral surface of the outer container. The outer container has a plurality of openings so as not to interrupt the airflow from the dust separation chamber into the intake duct.

An operating lever is disposed outside the outer container in a diameter direction of the outer container to allow a user to manipulate the outer container. The operating lever is located outside the dust separation chamber.

Therefore, when the user manipulates the operating lever and moves the outer container downward together with the compression plate, the bristles on the inner surface of the outer container clean the filter provided along the outer circumference of the intake cylinder, and the compression plate compresses the storage in the dust receiving chamber in the dust.

However, according to Patent Document 2, since the outer container is configured to surround the entire intake cylinder without manipulating the operating lever, a plurality of openings are formed in the outer container to allow air to pass through the outer container.

However, even if a plurality of openings are provided in the outer container, the portion without the openings acts as a resistance to airflow, so there is a disadvantage that airflow performance is lowered.

In addition, since the outer container is located outside the intake cylinder, the dust in the dust separation chamber may come into contact with the outer container in a state where the operating lever is not manipulated. For this reason, there is the disadvantage that the outer container is contaminated and an operation to clean the outer container is additionally required.

In addition, according to Patent Document 2, since the operation lever is provided outside the dust separation chamber, it is necessary to provide a slit in the upward/downward direction in the dust separation chamber to allow the operation lever to move in the upward/downward direction.

Because the operating lever cannot cover the entire slot, there is a problem that air and dust in the dust separation chamber leak to the outside through the slot.

In addition, in the case of Patent Document 2, there is no structure to move the outer container upward or downward without shifting, and therefore, there is a problem that the upward and downward movement of the outer container cannot be performed smoothly.

In addition, in the case of Patent Document 2, since the user manipulates the operation lever after separating the dust collecting case from the cleaner body, this causes inconvenience for the user in use. [Related technical literature]

Hereinafter, the vacuum cleaner according to the present invention will be described with reference to the accompanying drawings.

1 to 6 are views related to a vacuum cleaner according to a first embodiment of the present invention. 1 is a perspective view showing the appearance of a vacuum cleaner according to a first embodiment of the present invention; FIG. 2 is a view showing a state in which the vacuum cleaner according to the first embodiment of the present invention is laid flat and placed on a floor surface; An exploded perspective view of the main components of the vacuum cleaner according to the first embodiment of the present invention.

In addition, FIG. 4 is a perspective view showing the main parts of the dust box according to the first embodiment of the present invention; FIG. 5 is a cross-sectional view showing a state where the dust box according to the first embodiment of the present invention and a motor case are coupled; and FIG. 6 is a cross-sectional view showing a state in which the lower portion of the filter portion according to the first embodiment of the present invention is placed on the dust guide.

1 to 6 , the vacuum cleaner according to the first embodiment of the present invention may include a dust box 100 . The dust box 100 may include a pipe joint 110 through which air containing dust is introduced. The pipe joint 110 may guide the dust-laden air to the dust box 100 .

The cleaner may further include: a motor housing 200 having a lower portion coupled to the dust box 100 ; and a handle portion 300 coupled to the motor housing 200 .

For example, the handle portion 300 may be located on the motor housing 200 to be opposite to the pipe joint 110 . However, the positions of the pipe joint 110 and the handle portion 300 are not limited thereto.

The dust box 100 may separate dust introduced into the dust box 100 through the pipe joint 110 and store the separated dust.

The dust separation part may be located in the dust box 100 . The dust separation part may include a first cyclone part 120 capable of separating dust using a cyclone flow. The first cyclone part 120 may communicate with the pipe joint 110 .

The air and dust introduced through the pipe joint 110 spirally flow along the inner peripheral surface of the first cyclone part 120 .

The dust separation part may further include a second cyclone part 130 configured to separate dust from the air discharged from the first cyclone part 120 .

The second cyclone part 130 may include a plurality of cyclone bodies 131 arranged in parallel. The air may pass through the plurality of cyclone bodies 131, respectively.

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

For example, each of the dust box 100 and the motor housing 200 may be formed in a cylindrical shape, wherein the motor housing 200 has a lower portion coupled to the dust box 100 .

The lower side of the dust box 100 can be opened or closed by a main body cover that is rotated through a hinge. However, the lower side of the dust box 100 may be integrally formed with the dust box body.

The cleaner according to the embodiment of the present invention may further include a filter part that filters dust to be discharged to the outside when passing through the suction part. The filter part may include a main filter 140 disposed in the dust box 100 and disposed to surround the second cyclone part 130 .

For example, the main filter 140 is formed in a cylindrical shape and guides the air separated from the dust by the first cyclone part 120 to the second cyclone part 130 . When the air passes through the main filter 140, the main filter 140 filters out dust.

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

Generally, the mesh portion 141 is manufactured by a method of forming fine holes in a thin metal plate using a machine tool such as a press. During this process, burrs may form around the holes formed due to the punching operation of the machine. The burrs accelerate a condition in which long human or animal hair is caught as air passes through the mesh during product use. For this reason, contaminants may not be able to separate from the burr structure even if the compression section operates.

Therefore, as an exemplary embodiment of the present invention, post-processing for smoothing the periphery of the pores may be performed after the mesh portion is produced. Post-processing removes the burrs formed around the holes, thereby smoothing the surface of the screen. Through this effect, hair or long contaminants trapped in the main filter 140 when the air passes through the main filter 140 can be easily separated by the compressed part.

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

Therefore, the vacuum cleaner according to the present invention may further include a compression part 150 , such as a simple cleaning system for cleaning the main filter 140 .

The compression part 150 may include: an operation part 151 provided in the motor housing 200 so as to be movable in an upward/downward direction in the dust box 100; and a manipulation part 153 configured to be manipulated by a user to be movable in an upward/downward direction The operation part 151 is moved downward; and the transmission part 155 is configured to transmit the operation force of the operation part 153 to the operation part 151 .

The manipulation part 153 may be provided outside the motor housing 200 . For example, the manipulation part 153 may be provided at a position higher than that of the motor 230 provided in the motor housing 200 . In addition, the manipulation portion 153 may be provided at a position higher than that of the manipulation portion 151 .

The transmission portion 155 is provided in the motor housing 200 and formed to be elongated in the upward/downward direction. The manipulation part 153 is coupled to the upper end of the transmission part 155, and the operation part 151 is coupled to the lower end of the transmission part 155.

The operation part 151 is positioned above the main filter 140 in a state where the operation part 153 is not operated, and when the operation part 153 is operated, the operation part 151 moves downward along the outer peripheral surface of the main filter 140 .

The handle portion 300 may include: a handle body 310 configured to be grasped by a user; and a battery housing 320 disposed below the handle body 310 and configured to accommodate the battery 330 .

The manipulation part 153 may be located on the left side of the handle body 310 in a state where the user grasps the handle body 310 with his/her right hand.

Therefore, the user can easily manipulate the manipulation part 153 with his/her left hand without holding the handle main body 310 .

In a state where the dust box 100 is placed on the floor, the manipulation part 153 may move in a direction parallel to the axis of the cyclone flow in the first cyclone part 120, for example, in an upward/downward direction.

A slot 210 may be formed in the motor housing 200 to allow the manipulation portion 153 to move. The slot 210 may also extend in a direction parallel to the extending direction of the axis of the cyclone flow in the first cyclone portion 120, that is, in an upward/downward direction.

However, the slot 210 may be formed in the handle body 310 .

In this embodiment, since the extension direction of the axis of the cyclone flow is the up-down direction in the drawings, for example, "the extension direction of the axis of the cyclone flow" to be described below can be understood to mean "upward/downward direction".

Referring to FIG. 2 , the diameter D1 of the motor housing 200 may be longer than the horizontal length L1 of the handle portion 300 . Also, the handle part 300 may be coupled to the motor case 200 such that the center of the handle part 300 in the left/right direction coincides with the center of the motor case 200 .

For example, the manipulation part 153 may be located at a boundary portion where the motor housing 200 and the handle part 300 contact each other.

When the cleaner is placed such that the motor case 200 and the handle part 300 are in contact with the floor F, due to the difference between the diameter D1 of the motor case 200 and the horizontal length L1 of the handle part 300, the outer peripheral surface of the motor case 200, A space is defined between the outer peripheral surface of the handle part 300 and the floor F, and the manipulation part 153 may be located in the space.

In this state, the manipulation portion 153 is spaced apart from the floor F.

Therefore, during the process of placing the cleaner on the floor F, the manipulation portion 153 can be prevented from colliding with the floor F, so that the manipulation portion 153 can be prevented from being damaged or being inadvertently operated.

For example, the transmission part 155 may be provided in the form of a round bar, and the manipulation part 153 may be coupled to an upper end of the transmission part 155 . That is, the transmission part 155 may have a circular horizontal cross section.

In addition, the transmission part 155 may also extend in a direction parallel to the extending direction of the axis of the cyclone flow of the first cyclone part 120 .

Since the operation part 151 is located inside the motor housing 200 and the manipulation part 153 is located outside the motor housing 200 , the transmission part 155 may be located inside the motor housing 200 to connect the operation part 151 and the manipulation part 153 . That is, the manipulation part 153 may penetrate the motor housing 200 .

A compression rail part 220 for guiding upward/downward movement of the transmission part 155 may be provided in the motor housing 200 .

The compression rail part 220 may extend in a direction parallel to the extending direction of the axis of the cyclone flow of the first cyclone part 120 .

Therefore, the transmission part 155 can move in the upward/downward direction in the compression rail part 220 .

A motor 230 for generating suction may be provided in the motor housing 200 . The suction force generated by the motor 230 may be applied to the fitting 110 .

The motor 230 may be disposed above the dust box 100 and the battery 330 based on the extending direction of the axis of the cyclone flow of the first cyclone part 120 . The manipulation part 153 may be provided at a height equal to that of a part of the motor 230 , or at a position higher than that of the motor 230 .

An air guide 240 may be provided in the motor housing 200 to guide the air discharged from the second cyclone part 130 to the motor 230 .

The second cyclone part 130 may be coupled to the lower part of the air guide 240 . In a state where the main filter 140 is coupled to the second cyclone part 130 , the main filter 140 surrounds the second cyclone part 130 .

Therefore, the main filter 140 may also be located below the air guide 240 . In a state where the manipulation part 153 is not manipulated, the manipulation part 151 may be provided at a position surrounding the air guide 240 .

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

In this embodiment, the position of the operation part 151 can be referred to as the standby position of the simple cleaning system when the operation part 153 is not operated.

In the standby position of the simple cleaning system, the operation part 151 may be provided so as not to overlap the main filter 140 . Therefore, the air can pass through the main filter 140 .

For example, in the standby position, the operation portion 151 may be positioned higher than the position of the main filter 140 . Therefore, in the standby position, the operation portion 151 can be prevented from acting as a flow resistance during the process of air passing through the main filter 140 .

The dust guide 160 may be disposed under the second cyclone part 130 . The lower part of the second cyclone part 130 may be coupled to the upper part of the dust guide 160 . Also, the lower portion of the main filter 140 may be seated on the dust guide 160 .

A lower portion of the dust guide 160 may be seated on the bottom surface of the dust box 100 . The dust guide 160 is spaced apart from the inner peripheral surface of the dust box 100 so that the inner space of the dust box 100 is divided into: a first dust storage part 161 configured to store dust separated by the first cyclone part 120; and a second dust The storage part 163 is configured to store the dust separated from the second cyclone part 130 .

The first dust storage portion 161 is defined by the inner peripheral surface of the dust box 100 and the outer peripheral surface 163 b - 3 of the dust guide 160 , and the second dust storage portion 163 is defined by the inner peripheral surface of the dust guide 160 .

In the case where the main body cover is provided, the lower part of the dust guide 160 may be seated on the main body cover.

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

Furthermore, in the standby position, the compression plate is in standby at a position away from the main filter 140 . During the cleaning process, the compression plate moves in the upward/downward direction while wiping the outer surface of the main filter 140 .

The inner peripheral surface of the compression plate may include a cleaning surface that contacts the outer surface of the main filter 140 during the cleaning process. The cleaning surface is a surface, that is, a vertical surface facing the main filter 140 .

Therefore, when the compression plate moves downward in a state where the entire cleaning surface is in contact with the circumference of the main filter 140 , the cleaning surface removes dust adhering to the outer surface of the main filter 140 .

The diameter of the cleaning surface may be smaller than the diameter of the main filter 140 . In this embodiment, since the compression plate is made of an elastically deformable material, the compression plate may be radially outward of the main filter 140 during the process of moving the compression plate downward and the cleaning surface in contact with the main filter 140 elastic deformation. In a state in which the compression plate is elastically deformed, the cleaning surface may be in contact with the main filter 140 .

That is, in a state where the cleaning surface is in contact with the main filter 140 , the cleaning surface can compress the main filter 140 . As described above, since the cleaning surface cleans the main filter 140 in a state where the cleaning surface compresses the main filter 140 , dust adhering to the main filter 140 can be effectively removed from the main filter 140 .

In addition, since the compression plate is made of elastically deformable material, and the entire periphery of the sweeping surface compresses the main filter 140, even if the center of the compression plate is inclined with respect to the axis of the cyclone flow, during the downward movement process of the compression plate The state in which the cleaning surface of the compression plate compresses the main filter 140 can be maintained, so that the main filter 140 can be cleaned.

The compression plate may include inclined surfaces extending obliquely radially upward and outward from the sweeping surface.

Since the inclined surface is inclined upward and outward, the inner diameter of the inclined surface of the compression plate increases toward the upper side. Further, the inclined surface is spaced apart from the outer peripheral surface of the main filter 140 .

The operation part 151 may further include: a frame configured to support the outer circumference of the compression plate; and a core portion configured to support the inner circumference of the compression plate.

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

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

The coupling protrusions may be formed on the compression plate, the coupling holes may be formed in the core, and the core may be coupled to the compression plate by inserting the coupling protrusions into the coupling holes.

The frame supports the compression plate and is coupled to the core, thereby fixing the position of the compression plate.

The transmission part 155 may be provided in the form of a long cylindrical rod. The purpose of this configuration is to enable the transmission portion 155 to move smoothly when the transmission portion 155 moves in the upward/downward direction in the motor housing 200 .

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

The dust guide 160 may include: a storage wall 163 a configured to define the second dust storage part 163 ; and a support part 163 b disposed on the upper side of the storage wall 163 a and configured to support the second cyclone part 130 .

The storage wall 163a is provided in a columnar form having a circular horizontal section, and the diameter of the storage wall 163a decreases from the upper side to the lower side, so that the space of the first dust storage part 161 is maximized.

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

For example, the anti-scattering rib 165 may be formed in a cylindrical shape, and may surround the upper portion of the storage wall 163a in a state where the anti-scattering rib 165 is spaced from the storage wall 163a.

Since the diameter of the storage wall 163a decreases toward the lower side, a space is defined between the outer peripheral surface of the storage wall 163a and the anti-scattering rib 165 .

The cyclone flow may move downward while flowing along the inner peripheral surface of the dust box 100 . During the downward movement of the cyclone flow, when the cyclone flow reaches the body cover or the bottom surface of the dust box 100, the cyclone flow may become an upward flow again.

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

In the case of the present embodiment, the upward flow in the first dust storage portion 161 is changed to downward flow again by the anti-scattering ribs 165 in the space between the anti-scattering ribs 165 and the storage wall 163a.

Therefore, the dust stored in the first dust storage part 161 can be prevented from scattering, so that the reverse flow of the dust to the second cyclone part 130 can be prevented.

Since the anti-scattering ribs 165 extend downward from the upper end of the storage wall 163a, the dust separated by the first cyclone part 120 can smoothly move to the first dust storage part 161 through the anti-scattering ribs 165 together with the cyclone flow.

Meanwhile, the support part 163b may include an insertion part 163b - 1 inserted into the lower part of the main filter 140 . When the insertion part 163b-1 of the support part 163b is inserted into the lower part of the main filter 140, the lower end of the main filter 140 is seated on the support surface 163b-2 around the insertion part 163b-1 of the support part 163b.

In a state where the main filter 140 is seated on the support surface 163b-2, the compression plate passes through the main filter 140 while moving downward.

The diameter of the outer peripheral surface 163b-3 of the support portion 163b may be reduced toward the lower side to prevent the outer peripheral surface 163b-3 of the support portion 163b from interfering with the compression plate during the downward movement of the compression plate. 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 peripheral surface 163b - 3 of the support portion 163b may be equal to or smaller than the diameter of the outer peripheral surface of the main filter 140 .

In addition, when the dust stored in the first dust storage part 161 is compressed while the compression plate moves downward, since the outer peripheral surface 163b-3 of the support part 163b is inclined inward, the compressed dust can easily move downward .

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

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

The manipulation part 153 may include a first part located inside the motor housing 200 ; and a second part extended in a horizontal direction from the first part and located outside the motor housing 200 .

The transmission part 155 is connected to this first part. The first portion may have a fitting groove into which a portion of the transmission portion 155 is fitted.

The horizontal cross section of a portion of the transmission portion 155 inserted into the fitting groove may be formed to be non-circular, thereby preventing relative rotation between the transmission portion 155 and the manipulation portion 153 during the manipulation of the manipulation portion 153 .

Since the user needs to push the second part, the horizontal width of the second part may be larger than the horizontal width of the first part.

Specifically, although not shown in the figure, in a state where the compression part 150 is located at the standby position, an elastic member for elastically supporting the manipulation part 153 may be supported on the compression rail part 220 .

In the section in which the manipulation part 153 moves downward, the elastic member may not provide elastic force to the manipulation part 153 except for the initial section.

Therefore, since the elastic member supports the manipulation portion 153 , the compression portion 150 can be prevented from moving downward unintentionally due to the load of the compression portion 150 .

The elastic member may have various shapes and structures.

Meanwhile, in the cleaner according to the present invention, the compression rail part 220 for guiding the upward/downward movement of the transmission part 155 is not provided outside the dust box 100, and the upward/downward movement of the transmission part 155 is only controlled by the motor The compression rail portion 220 in the housing 200 guides.

Therefore, compared with the case where the compression rail part 220 is provided on the outer peripheral surface of the dust box 100 , the outer diameter of the dust box 100 can be increased, so that the space between the inner peripheral surface of the dust box 100 and the second cyclone part 130 can be ensured. Sufficient interval d1.

For example, since the interval d1 of 14 mm or more can be ensured between the inner peripheral surface of the dust box 100 and the second cyclone part 130 , foreign matter such as grain flakes can be effectively prevented from being caught at the outlet of the pipe joint 110 .

In this embodiment, when the user manipulates the manipulation portion 153 in one direction, the manipulation portion 151 can move downward. In a state where the operation part 151 is moved downward to the lowered position, the user can return the operation part 151 to the standby position by moving the operation part 153 in the other direction.

In the present embodiment, the cleaner may not have the return means for returning the operation part 151 from the lowered position to the standby position, but a return means may be provided.

The pipe joint 110 coupling the suction part is coupled to the dust box 100, and the dust box 100 provided with the pipe joint 110 is coupled to the motor housing 200 to be detachable in the upward/downward direction.

In order to detachably couple the dust box 100 and the motor housing 200, the dust box 100 and the motor housing 200 may have a coupling device.

For example, referring to FIG. 4 , the threaded portion 170 to be coupled to the motor housing 200 may be provided at the upper end of the dust box 100.

However, a coupling device having another structure may be provided instead of the threaded portion 170 .

In order to increase the sealing force between the dust box 100 and the motor housing 200, which are detachably coupled in the upward/downward direction, the sealing member 180 may be located at a contact portion between the dust box 100 and the motor housing 200, for example, at the upper end of the dust box 100 .

As described above, since the dust box 100 and the motor case 200 are provided to be separable in the upward/downward direction, the sealing force between the dust box 100 and the motor case 200 can be increased.

The electrical end portion 250 is located on the motor housing 200 and is disposed adjacent to the pipe joint 110 . When the suction part is coupled to the pipe joint 110, the electrical end 250 is coupled to one end of the suction part and supplies power to the suction part.

When using the prior art vacuum cleaner in which the energized wires and the ends are connected to the cleaner body and the dust box, it is not easy to clean the dust box with water. In particular, when the vacuum cleaner is operated in a state where the consumer carelessly washes the vacuum cleaner with water without removing moisture, an electrical short circuit may occur, causing a safety problem.

Conversely, since the vacuum cleaner according to the present invention has the electrical end 250 mounted on the motor housing 200, the dust box containing no electrical components can be separated from the motor housing and then washed with water to meet consumer needs. In addition, the length of the wires of the motor and/or the inverter can be reduced.

Further, a structure such as a strength enhancing lead wire or the like for enhancing the strength of the pipe joint 110 connected to the suction part may be provided at the lower part of the pipe joint 110 of the dust box 100 .

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

7 is an exploded perspective view showing a vacuum cleaner according to a second embodiment of the present invention; and FIG. 8 is a view showing a state where a dust box and a motor housing of the vacuum cleaner according to the second embodiment of the present invention are coupled.

In addition, FIGS. 9 to 16 are views showing a process of separating the dust box and the motor case of the cleaner according to the second embodiment of the present invention.

In the description of the vacuum cleaner according to the second embodiment, the same constituent elements as those of the vacuum cleaner according to the first embodiment described above will be given the same reference numerals, and descriptions thereof will be omitted.

The vacuum cleaner according to the second embodiment differs from the vacuum cleaner according to the first embodiment in that the pipe joint is fixedly coupled to the motor housing instead of the dust box; and provision is made for tightening/releasing the dust box and the pipe joint Structure.

The vacuum cleaner according to the present embodiment will be described. The pipe joint 110 - 1 is fixedly coupled to the motor housing 200 instead of the dust box 100 .

In addition, the cleaner may further include a fastening portion 400 configured to couple the dust box 100 to the motor housing 200 such that the dust box 100 and the motor housing 200 are detachable.

The fastening part 400 includes: a button 410 located below the pipe joint 110 - 1 ; and a hook 420 located in a space between the button 410 and the dust box 100 . In this case, the hook 420 may be referred to as a front hook 420 or a first hook 420 to distinguish it from the hook 470 provided between the dust box 100 and the pull rod 460 to be described below. In addition, the hook 470 disposed between the pull rod 460 and the dust box 100 may be referred to as a rear hook 470 or a second hook 470 .

When the button 410 is pressed, the hook 420 can rotate clockwise.

The fastening part 400 further includes a first snap protrusion 430 located on the outer surface of the dust box 100 .

The first snap protrusion 430 is fastened to and/or released from the hook 420 according to whether the hook 420 is rotated.

The fastening portion 400 further includes a second snap protrusion 440 located on a lower portion of the outer surface of the dust box 100 opposite to the first snap protrusion 430 .

The second snap protrusion 440 is coupled to the groove 340 of the handle part 300 .

The hook 420 has a first inclined surface 421 configured to contact the rib 411 to rotate the hook 420 clockwise, and a second inclined surface 422 extending from the first inclined surface 421 and configured to rotate the hook 420 counterclockwise.

In FIG. 7, undescribed reference numeral 510 denotes a HEPA filter, undescribed reference numeral 520 denotes a pre-filter, and undescribed reference numeral 530 denotes a dust cover.

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

The HEPA filter 510 and the pre-filter 520 may be disposed on the upper side of the motor housing 200 . Therefore, the air passing through the cyclones 120 and 130 may be filtered again before the air is discharged to the outside of the cleaner 1 via the motor 230 .

Specifically, the HEPA filter 510 is coupled to the upper portion of the motor housing 200 and may filter dust before the air passing through the motor 230 is discharged to the outside.

In addition, the pre-filter 520 is disposed to surround at least a portion of the motor 230 and may filter out dust before the air passing through the cyclones 120 and 130 is introduced into the motor 230 . In the embodiment shown in 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 corresponding to the shape of the motor. The HEPA filter 510 may be formed in a circular plate (disc) shape having a predetermined height so that the HEPA filter 510 is fitted and coupled to the upper portion of the motor housing 200.

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

Furthermore, according to the fastening part 400 of the embodiment shown in FIG. 7 , the dust box 100 is coupled to the motor housing 200 in a state in which the hook 420 and the first snap protrusion 430 are kept fastened to each other, and the second snap protrusion 440 is coupled to the groove 340 of the handle portion 300 (see FIGS. 8 and 9 ).

In this state, when the button 410 is pressed in the opposite direction to the dust box 100 to separate the dust box 100 from the motor housing 200, the rib 411 presses the first inclined surface 421 of the hook 420 downward, so that the hook 420 is clockwise Rotate, and the hook 420 and the first snap protrusion 430 are released (see FIG. 10 ).

Further, the clockwise rotation of the hook 420 is performed until the rib 411 reaches the boundary point between the first inclined surface 421 and the second inclined surface 422 (see FIG. 11 ). The hook 420 starts to rotate counterclockwise at a time point when the rib 411 passes the boundary point between the first inclined surface 421 and the second inclined surface 422 and comes into contact with the second inclined surface 422 (see FIG. 12 ).

When the front part of the dust box 100 (the part directed to the pipe joint) is pushed down in a state where the hooks 420 and the first snap protrusions 430 are released as described above, the dust box 100 is slightly rotated around the second snap protrusions 440 (See Figure 13).

After that, the dust box 100 is slightly pushed forward, so that the second snap protrusions 440 are separated from the grooves 340 of the handle part 300 (see FIG. 14 ). The rear of the dust box 100 is pushed downward again, so that the dust box 100 is separated from the motor housing 200 .

After the dust box 100 is separated from the motor housing 200 through the above process, the dust box 100 is cleaned. The cleaned dust box 100 is coupled to the motor housing 200 again in the reverse order of the above process.

Meanwhile, the end portion 250 is located on the motor housing 200 and is disposed adjacent to the pipe joint 110-1. When the suction portion is coupled to the fitting 110-1, the end portion 250 supplies power to the suction portion.

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

17 is a perspective view showing the appearance of the vacuum cleaner according to the third embodiment of the present invention when viewed from the rear side; and FIG. 18 is a view showing a state where the dust box and the motor housing of the vacuum cleaner according to the third embodiment of the present invention are coupled Sectional drawing. In addition, FIGS. 19 and 20 are views showing a state in which the pull rod of the vacuum cleaner according to the third embodiment of the present invention is operated; and FIGS. 21 and 22 are views showing the dust box when the pull rod of the vacuum cleaner according to the third embodiment of the present invention is operated. A view of the detached state.

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

The pull rod 460 may be disposed on a side of the handle part 300 adjacent to the dust box 100 . In addition, the position of the pull rod 460 may be set above the battery housing 320 to allow the user to conveniently grasp the pull rod 460 . That is, the pull rod 460 may be provided in an idle space where the handle body 310 and the battery case 320 are not provided, so that the user can easily grasp the pull rod 460 . Therefore, the user can hold the handle body 310 with one hand and manipulate the pull rod 460 with the other hand.

17 to 20 , the pull rod 460 includes: a grip portion 461 configured to be grasped by a user to perform a pulling operation; a shaft 462 ;

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

The gripping portion 461 may be recessed by a predetermined depth to improve the convenience for the user to grasp the gripping portion 461 . As another example, the gripping portion 461 may be provided in the form of a protruding rod, or the gripping portion 461 may have various shapes modified to allow a user to conveniently hold the gripping portion 461 .

In addition, when viewing the pipe joint 110 or the electrical end portion 250 from the handle body 310 , the grip portion 461 may be disposed to face the left side. This is because many users are generally right-handed, so the user can conveniently manipulate the grip portion 461 with his/her left hand while gripping the handle body 310 with his/her right hand. However, the present invention is not limited thereto, and for the same reason, the gripping portion 461 may be arranged to face the right side, so that the left-handed user can conveniently use the gripping portion 461 or the gripping portion 461 can be conveniently designed.

When the user pulls the pull rod 460 , the separation arm 463 rotates and pushes the second hook 470 . Specifically, when the user rotates the grip portion 461 counterclockwise, the separation arm 463 can rotate clockwise around the shaft 462. Therefore, the separation arm 463 pushes the extension 471 of the rear hook 470 toward the pipe joint 110 (see FIG. 22 ).

21 and 22 , the rear hook 470 includes: an extension portion 471 configured to contact the pull rod 460; a snap portion 472 configured to catch the third snap protrusion 450 to fix the position of the dust box 100; and an elastic portion 473 , with an elastomer.

The extension part 471 and the buckle part 472 are connected to each other. A part of the extension part 471 and a part of the catching part 472 connected to each other may have a shape corresponding to one end of the third catching protrusion 450 to stably fix the position of the third catching protrusion 450 .

The extension portion 471 rotates a snap portion 472 (see FIG. 22 ) connected to one end of the extension portion 471 when rotated counterclockwise around the elastic portion 473 . Therefore, the end of the third snap protrusion 450 that is held in place by the snap portion 472 is separated from the portion of the extension portion 471 and the portion of the snap portion 472 that are connected to each other. In addition, the third snap protrusion 450 is separated, and the dust box 100 can be naturally released downward in the direction of gravity from the fixed position.

A torsion spring may be selected as the elastic body provided in the elastic portion 473 . Therefore, in a state in which the extension portion 471 is rotated by an external force, the extension portion 471 receives an elastic restoring force that restores the extension portion 471 to the original state. Therefore, when the user ends the manipulation of the pull rod 460, the rear hook 470 is restored to the original state.

23 is a view showing a state in which the separated dust box is coupled to the motor housing of the cleaner according to the third embodiment of the present invention; FIGS. 24 to 26 are views showing the fastening of the dust box to the cleaner according to the third embodiment of the present invention 27 to 29 are enlarged views showing the process of fastening the dust box to the front hook in the vacuum cleaner according to the third embodiment of the present invention.

Referring to FIG. 23 , the dust box 100 may be coupled to the motor housing 200 . In the third embodiment of the present invention, the dust box 100 may be coupled by being pushed in the vertical direction based on the direction of gravity in a state where the handle part 300 is not individually manipulated. Hereinafter, the process of fastening the dust box 100 to the front hook 420 and the rear hook 470 will be described in detail with reference to FIGS. 24 to 29 .

24 to 26 , the dust box 100 according to the third embodiment of the present invention is fastened to the rear hook 470 at the side of the handle body 310 . Specifically, the third snap protrusion 450 of the dust box 100 may be fastened to the rear hook 470 .

When the user moves the dust box 100 in the vertical direction, the third catching protrusion 450 and the catching portion 472 of the rear hook 470 may contact each other (see FIG. 24 ). The third inclined surface 452 (see FIG. 25 ) of the third snap protrusion 450 may be inclined downward in the radial direction of the dust box 100 . In addition, in a normal state in which the rear hook 470 does not rotate, the catching portion 472 may be inclined downward from the dust box 100 toward the handle body 310 .

The inclination angle of the third inclined surface 452 is gentler than the inclination angle of the locking portion 472 in the horizontal direction. Therefore, when the user moves the dust box 100 upward with the third inclined surface 452 and the catching part 472 in contact with each other, the catching part 472 may be pushed toward the handle body 310 and the rear hook 470 may rotate counterclockwise.

The counterclockwise rotation of the rear hook 470 may be performed until one end of the catch portion 472 leaves the boundary of the third inclined surface 452 (see FIG. 25 ). When the end of the latching portion 472 leaves the boundary of the third inclined surface 452 , there is no obstacle above the third latching protrusion 450 that restricts the upward movement of the dust box 100 . Therefore, the dust box 100 can be moved upward to a height where the dust box 100 is fixed to the motor housing 200 by the user's effort.

When the protruding portion 451 of the third latching protrusion 450 moves upward to the height at which the protruding portion 451 passes the end of the latching portion 472 , the pressing operation of the hook 470 after rotating counterclockwise ends. As described above, the elastic part 473 of the rear hook 470 may include the torsion spring, and the rear hook 470 may be restored to the original state by the rotational restoring force of the torsion spring. That is, the rear hook 470 can rotate clockwise.

The groove recessed by a predetermined depth may be defined by the difference in angle at the connection point between the catch portion 472 and the extension portion 471 . The protrusion 451 may be formed in a shape corresponding to the groove. Therefore, in a state where the rear hook 470 is restored to the original state, the protrusion 451 may be fastened to the groove, that is, the connection point between the catch portion 472 and the extension portion 471 (see FIG. 26 ).

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 snap protrusion 430 . Specifically, the front hook 420 may be moved from the dust box 100 toward the pipe joint 110 by being pushed by the first snap protrusion 430 .

Referring to FIG. 27 , in the third embodiment of the present invention, the first snap protrusions 430 may be inclined downward and protrude from the outer peripheral surface of the dust box 100 .

Specifically, the upper inclined surface 431 of the first snap protrusion 430 may be inclined downward from the dust box 100 toward the pipe joint 110 . The upper inclined surface 431 may be in contact with the end of the front hook 420 . Therefore, when the dust box 100 is moved upward, the front hook 420 may be pushed and moved toward the pipe joint 110 along the upper inclined surface 431 (see FIG. 28 ).

The fastening part 400 may further include: a link 425 which is a channel along which the front hook 420 can be pushed to move; and an elastic body 424 provided in a space between the link 425 and the front hook 420 ( See Figure 29).

The link 425 may have a space in which one end of the front hook 420 is fastened. Therefore, the link 425 can guide the path in which the front hook 420 moves.

The elastic body 424 may be disposed between one end of the front hook 420 and the front boundary of the link. In the third embodiment of the present invention, a compression spring (or a coil spring) can be selected as the elastic body 424 .

When the user moves the dust box 100 upward in the direction of gravity, the front hook 420 and the first snap protrusion 430 may contact each other (see FIG. 27 ).

When the user continuously moves the dust box 100 upward in a state where the front hook 420 and the first snap protrusion 430 are in contact with each other, the front hook 420 may be pushed forward along the inclination of the upper inclined surface 431 to move (see FIG. 28 ). The front hook 420 can move in the horizontal direction along the route of the link 425 . In this case, the elastic body 424 provided in the link 425 may be compressed by the front hook 420 . Therefore, the elastic body 424 can 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 is away from the boundary of the upper inclined surface 431 . When the end of the front hook 420 leaves the boundary of the upper inclined surface 431 , there is no obstacle above the first snap protrusion 430 that restricts the upward movement of the dust box 100 . Therefore, the dust box 100 can be moved upward to a height at which the dust box 100 is fixed to the motor housing 200 by the user's effort.

When the dust box 100 moves upward and the force for pushing the front hook 420 toward the pipe joint 110 is removed, the front hook 420 may move toward the handle body 310 again by the restoring force of the elastic body 424 . In this case, the protrusion 432 of the first snap protrusion 43 may be caught and fastened in the groove formed in the front hook 420 (see FIG. 29 ).

According to the vacuum cleaner according to the third embodiment of the present invention as described above, the user can couple the separate dust box 100 to the motor housing 200 by moving the dust box 100 upward in the direction of gravity without a separate manipulation. Therefore, the user can install the dust box more intuitively and conveniently.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art to which the present invention pertains will appreciate that any other specific forms may be employed without changing the technical spirit or essential characteristics.
