Description

Cleaner {Cleaner}

The present invention relates to a vacuum cleaner.

A vacuum cleaner is a device that performs cleaning by sucking or wiping dust or foreign substances in an area to be cleaned.

Such cleaners may be classified into manual cleaners for cleaning while the user directly moves the cleaner, and automatic cleaners for cleaning while driving themselves.

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

Korean Patent Registration No. 10-1127088 (registration date: March 8, 2012), which is a prior document, discloses a handheld vacuum cleaner.

The handheld vacuum cleaner includes a suction tube, an airflow generator, a centrifugal separator, a power source and a handle.

The airflow generator is also located within the motor housing and takes the form of a motor and fan assembly. A pre-motor filter is provided at the front of the motor, and a post-motor filter is provided at the rear of the motor.

At this time, when the filter is used for a long time, dust may accumulate on the filter, and if the filter is not cleaned, the dust accumulated on the filter acts as flow resistance, resulting in a decrease in suction performance.

By the way, in the case of the prior literature, in order to clean the filter, it is necessary to take out the filter after disassembling the handheld vacuum cleaner. Therefore, there is a disadvantage in that it is not easy for the user to clean the filter.

An object of the present invention is to provide a cleaner in which a user can easily separate a filter mechanism in which a filter is accommodated.

Another object of the present invention is to provide a vacuum cleaner capable of maintaining a sealing state when a filter mechanism is mounted on a main body.

Another object of the present invention is to provide a vacuum cleaner in which a pre-filter can be separated in a state in which a filter mechanism is separated.

A cleaner of the present invention for achieving the above object includes a main body having an opening, a suction motor accommodated in the main body and generating a suction force, and an exhaust filter for filtering air discharged from the suction motor, and including a filter mechanism that can be accommodated in the main body through the opening and can be separated from the main body.

A part of the filter mechanism protrudes outward from the body in a state where the filter mechanism is coupled to the main body so that a user can easily hold the filter device.

In a state in which the filter device is coupled to the main body, the filter device may be seated on an upper end of the main body.

In a state where the filter mechanism is coupled to the main body, a part of the exhaust filter is positioned inside the main body, and another part is positioned outside the main body, so that the contact area contacting air is increased.

In addition, the exhaust filter may be formed in a circular ring shape to increase a contact area with air.

The main body may further include a dust separator for separating dust by a cyclone flow, and an axis of the cyclone flow may pass through the filter mechanism.

The filter device may be coupled to the main body in a rotational manner, and a height of the filter device relative to the bottom surface may be varied while the filter device is rotated to engage or disengage the filter device.

A flow guide surrounding the suction motor and guiding air flow may be further included.

The filter mechanism may further include a filter frame accommodating the exhaust filter and having an air outlet.

The filter frame may be fixed to the flow guide.

In order to fix the filter frame to the flow guide, the flow guide includes a fixing rib, and the filter frame includes a rib accommodating portion in which the fixing rib is accommodated.

The fixing rib may extend in a circumferential direction of the flow guide and extend obliquely, and the rib accommodating portion may extend in a circumferential direction of the filter frame but obliquely so that a height thereof is variable during the coupling process of the filter mechanism.

The fixing rib may include a fixing protrusion so that the filter frame is firmly fixed to the flow guide, and the filter frame may include a slot into which the fixing protrusion is inserted while the fixing rib is accommodated in the rib accommodating part.

The filter frame may include an inner frame and an outer frame spaced apart from the inner frame. The exhaust filter may be accommodated between the inner frame and the outer frame.

The filter frame may further include a filter cover covering a lower side of the exhaust filter positioned between the inner frame and the outer frame. An opening through which air passes may be formed in the filter cover.

The rib accommodating portion may be formed between the inner frame and the filter cover.

The filter cover may include an inclined rib coupling portion to which the fixing rib is coupled, and the inner frame may include a recessed portion for forming the rib accommodating portion together with the rib coupling portion.

The filter cover may include a ring-shaped inner body, an outer body spaced apart from the inner body, and a connection body connecting the inner body and the outer body and having an opening through which air passes.

In order for the filter frame to be combined with the flow guide, the flow guide may pass through the inner body.

The rib coupling part may be formed on the inner body, and the fixing rib may be formed on an outer circumferential surface of the flow guide.

A pre-filter for filtering air to be introduced into the suction motor may be further included.

The pre-filter may cover at least a portion of the suction motor. The pre-filter may be exposed to the outside in a state in which the filter mechanism is separated from the main body so that the user can separate the pre-filter.

The filter device may further include a filter frame accommodating the exhaust filter, and when the filter device is coupled to the main body, the exhaust filter may surround the pre-filter to prevent an increase in height of the cleaner.

The filter mechanism may include a filter frame accommodating the exhaust filter, and a sealing member coupled to an edge of the filter frame and preventing air from leaking between an inner circumferential surface of the main body and the filter frame.

A support surface on which the sealing member is seated may be provided on an inner circumferential surface of the main body.

A cleaner according to another aspect includes a suction motor accommodated in a body and generating a suction force; and an exhaust filter for filtering air discharged from the suction motor, and may include a filter device accommodated in the main body through the opening and detachable from the main body, wherein the filter device may be rotatably coupled to the main body, and a height of the filter device relative to a floor may be varied while the filter device is rotated to engage or disengage the filter device.

A cleaner according to another aspect includes a main body provided with an opening; a suction motor accommodated in the main body and generating a suction force; a first filter for filtering air to be introduced into the suction motor; and a filter mechanism including a second filter for filtering air discharged from the suction motor, accommodated in the main body through the opening, and separable from the main body. The first filter may surround at least a portion of the suction motor, and may be exposed to the outside in a state in which the filter mechanism is separated from the main body.

According to the proposed invention, the filter mechanism including the exhaust filter can be separated from the main body, so there is an advantage in that the filter can be cleaned.

In addition, since the filter mechanism is engaged and disengaged in a rotational manner, the user can easily separate the filter mechanism from the body while preventing the filter mechanism from being unintentionally separated from the body.

In addition, according to the present invention, since the pre-filter is exposed to the outside in a state in which the filter mechanism is separated from the main body, there is an advantage in that the pre-filter can be separated from the main body and cleaned.

1 to 5 , the cleaner 1 according to an embodiment of the present invention may include a main body 2.

The cleaner 1 may further include a suction part 5 coupled to the front of the main body 2 . The suction part 5 may guide air containing dust to the main body 2 .

The cleaner 1 may further include a handle part 3 coupled to the main body 2 . The handle part 3 may be located on the opposite side of the suction part 5 in the main body 2 .

That is, the main body 2 may be disposed between the suction part 5 and the handle part 3 .

The main body 2 may include a first body 10 and a second body 12 positioned above the first body 10 . The first body 10 and the second body 12 may be directly coupled or indirectly connected by an intermediate member.

The first body 10 and the second body 12 may be formed in a cylindrical shape, although not limited thereto.

And, the upper and lower sides of each of the first body 10 and the second body 12 are opened. That is, each of the bodies 10 and 12 may include an upper opening and a lower opening.

And, the suction part 5 may be coupled to the main body 2 such that the central portion of the suction part 5 is approximately positioned at the boundary between the first body 10 and the second body 12 .

The main body 2 may further include a dust separator for separating dust from the air sucked through the suction part 5 .

The dust separation unit may include, for example, a first cyclone unit 110 capable of separating dust by cyclone flow. At this time, the first body 10 includes the first cyclone part 110 .

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

An axis of cyclone flow of the first cyclone unit 110 may extend in a vertical direction.

The dust separation unit may further include a second cyclone unit 130 that separates dust from the air discharged from the first cyclone unit 110 again. At this time, the second cyclone part 130 may be located inside the first cyclone part 110 so that the size of the dust separator is minimized. The second cyclone unit 130 may include a plurality of cyclone bodies arranged in parallel.

As another example, the dust separation unit may have a single cyclone unit, and even in this case, the axis of the cyclone flow may extend in a vertical direction.

The first body 10 serves as a dust bin for storing dust separated from each of the cyclones 110 and 130 .

The main body 2 may further include a body cover 16 that opens and closes the lower side of the first body 10 . The body cover 16 can open and close the first body 10 by a rotational motion.

At least a part of the second cyclone part 130 may be located within the first body 10 .

A dust storage guide 124 may be disposed in the first body 10 to guide storage of the dust separated from the second cyclone unit 130 . The dust storage guide 124 is coupled to the lower side of the second cyclone part 130 and may contact the upper surface of the body cover 16 .

The dust storage guide 124 may divide the internal space of the first body 10 into a first dust storage unit 121 storing dust separated from the first cyclone unit 110 and a second dust storage unit 123 storing dust separated from the second cyclone unit 130.

The inner space of the dust storage guide 124 is the second dust storage unit 123, and the space between the dust storage guide 124 and the first body 10 is the first dust storage unit 121.

The body cover 16 may open and close the first dust storage unit 121 and the second dust storage unit 123 together.

The cleaner 1 may further include a suction motor 20 for generating suction force and a battery 40 for supplying power to the suction motor 20 .

The suction motor 20 may be located within the second body 12 . And, at least a part of the suction motor 20 may be located above the dust separator. Therefore, the suction motor 20 is located above the first body 10 .

The suction motor 20 may communicate with the outlet of the second cyclone part 130 .

To this end, the main body 2 may further include a discharge guide 28 connected to the second cyclone unit 130 and a flow guide 22 communicated with the discharge guide 28 .

For example, the discharge guide 28 is located above the second cyclone part 130, and the flow guide 22 is located above the discharge guide 28.

And, at least a part of the suction motor 20 is located inside the flow guide 22 .

Accordingly, the axis of the cyclone flow of the dust separator may pass through the suction motor 20 .

When the suction motor 20 is located above the second cyclone part 130, the air discharged from the second cyclone part 130 can flow directly toward the suction motor 20, so that the flow path between the dust separator and the suction motor 20 can be minimized.

The suction motor 20 may include an impeller 200 that rotates. The impeller 200 may be connected to a shaft 202 . The shaft 202 is arranged to extend in the vertical direction.

An extension of the shaft 202 (which may also be referred to as a rotation axis of the impeller 200) may pass through the first body 10. At this time, the axis of rotation of the impeller 200 and the axis of the cyclone flow generated in the first cyclone part 110 of the dust separator may be positioned on the same line.

According to the present invention, the flow path of the air discharged from the dust separation unit, that is, the air discharged upward from the second cyclone unit 130, toward the suction motor 20 is reduced, and the direction change of the air can be reduced, thereby reducing air flow loss.

When the flow loss of air is reduced, the suction power can be increased and the use time of the battery 40 for supplying power to the suction motor 20 can be increased.

The cleaner 1 may further include an upper motor housing 26 covering an upper part of the suction motor 20 and a lower motor housing 27 covering a lower part of the suction motor 20 . The suction motor 20 may be accommodated inside each motor housing 26 , and the flow guide 22 may be disposed to surround the upper motor housing 26 .

At least a portion of the flow guide 22 may be spaced apart from the upper motor housing 26 . In addition, at least a portion of the flow guide 22 may be spaced apart from the second body 12 .

Accordingly, the inner circumferential surface of the flow guide 22 and the outer circumferential surface of the upper motor housing 26 form the first air passage 232, and the outer circumferential surface of the flow guide 22 and the inner circumferential surface of the second body 12 form the second air passage 234.

The air discharged from the second cyclone unit 130 flows to the suction motor 20 along the first air passage 232, and the air discharged from the suction motor 20 flows along the second air passage 234 and then is discharged to the outside. Thus, the second air passage 234 serves as an exhaust passage.

The handle part 3 may include a handle 30 for a user's grip and a battery housing 410 disposed below the handle 30 .

The handle 30 may be located behind the suction motor 20 .

As for the direction, in the vacuum cleaner 1, the direction in which the suction unit 5 is located relative to the suction motor 20 is forward, and the direction in which the handle 30 is located is rearward.

The battery 40 may be located at the rear of the first body 10 . Accordingly, the suction motor 20 and the battery 40 are disposed so as not to overlap each other in the vertical direction, and may also be disposed differently in height.

According to the present invention, the heavy suction motor 20 is positioned in front of the handle 30 with respect to the handle 30, and the heavy battery 40 is positioned below the handle 30, so that the weight is evenly distributed throughout the cleaner 1. When the user cleans while holding the handle 30, strain on the user's wrist can be prevented. That is, since the heavy components are distributed and disposed at the front and rear of the cleaner 1, but are disposed at different heights, the center of gravity of the cleaner 1 can be prevented from leaning to one side.

Since the battery 40 is located below the handle 30 and the suction motor 20 is located in front of the handle 30, there is no structure above the handle 30. That is, the upper surface of the handle 30 forms part of the exterior of the upper surface of the cleaner 1 .

Therefore, it is possible to prevent one component of the cleaner 1 from coming into contact with the user's arm in the process of holding and using the handle 30 .

The handle 30 may include a first extension 310 that extends in a vertical direction and can be held by a user, and a second extension 320 extending from an upper side of the first extension 310 toward the suction motor 20. At least a portion of the second extension part 320 may extend in a horizontal direction.

The first extension part 310 may be provided with a movement limiting part 312 to prevent the user from moving his/her hand in the longitudinal direction of the first extension part 310 (vertical direction in FIG. 2) while holding the first extension part 310. The movement limiting part 312 may extend from the first extension part 310 toward the suction part 5 .

The movement limiting part 312 is spaced apart from the second extension part 320 . Accordingly, in a state in which the first extension part 310 is gripped, some fingers are located above the movement limiting part 312 and the rest of the fingers are located below the movement limiting part 312 .

For example, the movement limiter 312 may be positioned between the index finger and the middle finger.

According to this arrangement, the longitudinal axis A1 of the suction part 5 can pass the user's wrist while the user is gripping the first extension part 310 .

When the longitudinal axis A1 of the suction part 5 passes through the user's wrist, the longitudinal axis A1 of the suction part 5 may be substantially parallel to the extension direction of the user's arm in a state where the user's arm is extended. Accordingly, in this state, the user's force required when the user holds the handle 30 and pushes or pulls the cleaner 1 has the advantage of being minimized.

The handle 30 may include a manipulation unit 326 . For example, the control unit 326 may be located on an inclined surface formed on the second extension part 320 . An on command and an off command of the vacuum cleaner (suction motor) may be input through the control unit 326 .

The control unit 326 may be disposed to face a user. Based on the handle 30 , the control unit 326 may be positioned on the opposite side of the movement limiting unit 312 .

The control unit 316 is positioned higher than the movement limiting unit 312 . Accordingly, the user can easily manipulate the control unit 326 with a thumb while holding the first extension unit 310 .

In addition, since the manipulation unit 326 is positioned away from the first extension 310, when cleaning is performed while holding the first extension 310, unintentional manipulation of the manipulation unit 326 can be prevented.

A display unit 322 for displaying an operating state may be provided on the second extension part 320 . For example, the display unit 322 may be located on an upper surface of the second extension unit 320 . Therefore, the user can easily check the display unit 322 located on the upper surface of the second extension part 320 while cleaning. The display unit 322 may display, for example, the remaining amount of the battery 40 and the strength of the suction motor.

The display unit 322 is not limited, but may include a plurality of light emitting units. The plurality of light emitting units may be spaced apart from each other in the longitudinal direction of the second extension part 320 .

The battery housing 410 may be located below the first extension part 310 .

The battery 40 may be detachably coupled to the battery housing 410 . For example, the battery 40 may be inserted into the battery housing 410 from below the battery housing 410 .

The rear surface of the battery housing 410 and the rear surface of the first extension part 310 may form a continuous surface. Accordingly, the battery housing 410 and the first extension part 310 may have a sense of unity.

Meanwhile, referring to FIG. 3 , the cleaner 1 may further include a filter device 50 having an air outlet 522 through which air passing through the suction motor 20 is discharged. The air outlet 522 includes, for example, a plurality of openings, and the plurality of openings may be arranged in a circumferential direction. Thus, the air outlet 522 may be arranged in a ring shape.

The filter mechanism 50 may be detachably coupled to the upper side of the main body 2 . That is, the filter mechanism 50 may be detachably coupled to the second body 12 .

A part of the filter mechanism 50 is located outside the second body 12 in a state where the filter mechanism 50 is coupled to the main body 2 . Accordingly, a part of the filter mechanism 50 is introduced into the main body 2 through the upper opening of the main body 2, and the other part protrudes out of the main body 2.

The height of the body 2 may be substantially the same as that of the handle 30 . Accordingly, the filter device 50 protrudes upward from the main body 2 so that the user can easily separate the filter device 50 while holding the filter device 50 .

The air outlet 522 is located on the upper side of the filter device 50 in a state where the filter device 50 is coupled to the main body 2 . Thus, the air discharged from the suction motor 20 is discharged upward from the main body 2 .

According to this embodiment, in the process of cleaning using the cleaner 1, air discharged from the air outlet 522 may be prevented from flowing toward the user.

The main body 2 may further include a pre-filter 29 for filtering air introduced into the suction motor 20 . The pre-filter 29 may be located within the flow guide 22 . In addition, the pre-filter 29 is seated on the upper motor housing 26 and may surround a part of the upper motor housing 26 . That is, the upper motor housing 26 may include a filter support for supporting the pre-filter 29 .

6 is a view showing a filter device according to an embodiment of the present invention separated from a main body, FIG. 7 is a view looking down from the filter device according to an embodiment of the present invention, FIG. 8 is an exploded perspective view of the filter device of FIG. 7, and FIG. 9 is a cross-sectional perspective view of the filter device of FIG.

Referring to FIGS. 5 to 9 , the filter mechanism 50 may be separated from the main body 2 .

For example, the filter mechanism 50 may be separated upward from the main body 2 . In a state in which the filter device 50 is separated from the main body 2 , the pre-filter 29 may be exposed to the outside.

The pre-filter 29 may include a handle 29a. The user can separate the pre-filter 29 from the main body 2 by holding the handle 29a of the pre-filter 29 exposed to the outside and lifting the pre-filter 29 upward. Since the pre-filter 29 can be separated from the main body 2, the user can easily clean the pre-filter 29.

The filter mechanism 50 may further include an exhaust filter 560 for filtering air discharged from the suction motor 20 and a filter frame supporting the exhaust filter 560 .

In the present invention, the pre-filter 29 may be referred to as a first filter, and the exhaust filter 560 may be referred to as a second filter.

The exhaust filter 560 may be, for example, a high efficiency particulate air filter (HEPA filter).

The exhaust filter 560 may be disposed to surround the flow guide 22 so that the height of the cleaner 1 is prevented from being increased while the filter device 50 is coupled to the main body 2 .

That is, the exhaust filter 560 may be formed in a ring shape, for example, and a portion of the flow guide 22 may be positioned within an area formed by the filter 560 .

The exhaust filter 560 and the pre-filter 29 may be located together in an area formed by the second body 12 . That is, the exhaust filter 560 and the pre-filter 29 may be accommodated together in the same body.

When the exhaust filter 560 and the pre-filter 29 are positioned within the second body 12, at least a portion of the pre-filter 29 may be accommodated in a region formed by the exhaust filter 560 to prevent an increase in height. That is, the exhaust filter 560 may surround the pre-filter 29 .

With this structure, the axis of the cyclone flow of the first cyclone unit 110 may pass through the pre-filter 29 and the filter mechanism 50 . For example, an axis of the cyclone flow may pass through a region formed by the exhaust filter 560 . That is, the axis of the cyclone flow of the first cyclone unit 110 may pass through the central opening of the ring-shaped exhaust filter 560 .

The filter frame may be coupled to the flow guide 22 while being inserted between the second body 12 and the flow guide 22 .

The filter frame may include an inner frame 501 and an outer frame 540 disposed to surround the inner frame 501 .

An outer circumferential surface of the inner frame 501 and an inner circumferential surface of the outer frame 540 may be spaced apart from each other, and the exhaust filter 560 may be positioned between the inner frame 501 and the outer frame 540 .

The filter frame may further include an exhaust grill 520 in which the air outlet 522 is formed and covering an upper side of the exhaust filter 560, and a filter cover 570 covering a lower side of the exhaust filter 560.

Specifically, the inner frame 501 may include an upper surface portion 502 and a peripheral portion 503 extending downward from an edge of the upper surface portion 502 .

The circumferential portion 503 may include a first portion 503a and a second portion 503b extending downward from the first portion 503a and having a larger diameter than the first portion 503a.

A seating portion 506 for seating the exhaust grill 520 may be formed between the first portion 503a and the second portion 503b due to a difference in diameter between the first portion 503a and the second portion 503b.

The seating portion 506 is formed along the circumferential direction of the circumferential portion 503 at a position spaced downward from the upper surface portion 502 .

The exhaust grill 520 may be formed in a ring shape so that the exhaust grill 520 can be seated on the seating portion 506 . Also, the inner diameter of the exhaust grill 520 may be equal to or greater than the outer diameter of the first portion 503a of the circumferential portion 503 . Also, the outer diameter of the seating portion 506 and the outer diameter of the second part 503b may be larger than the inner diameter of the exhaust grill 520 .

Accordingly, the exhaust grill 520 may be seated on the seating portion 506 in a state where the upper surface portion 502 of the inner frame 501 and the first portion 503a of the circumferential portion 503 pass through the exhaust grill 520.

The filter mechanism 50 may further include an inner decorative member 510 coupled to an edge of the inner frame 501 . The inner decor member 510 may be formed in a ring shape.

The inner decor member 510 is provided with a hook 512 for being coupled to the inner frame 501 .

A hook coupling hole 508 to which the hook 512 is coupled may be formed in the inner frame 501 .

The hook coupling hole 508 may be formed in the first portion 503a of the circumferential portion 503 . In addition, a guide groove 507 for guiding the hook 512 to the hook coupling hole 508 may be formed in the first portion 503a of the circumferential portion 503 . The guide groove 507 may extend in a vertical direction.

Therefore, when the hook 512 of the inner decor member 510 moves along the guide groove 507 and aligns with the hook coupling hole 508, the hook 512 can be inserted into the hook coupling hole 508.

The inner decorative member 510 may be coupled to the inner frame 501 while the exhaust grill 520 is seated on the mounting portion 506 of the inner frame 501 .

To this end, a guide groove 524 may be formed on an inner circumferential surface of the exhaust grill 520 to provide a space in which the hook 512 of the inner decor member 510 can move. The guide groove 524 may extend in a vertical direction.

Accordingly, the hook 512 of the inner decor member 510 can move along the guide groove 507 of the inner frame 501 and the guide groove 524 of the exhaust grill 520 .

In a state where the inner decor member 510 is coupled to the inner frame 501 , the inner decor member 510 may be seated on an upper surface of the exhaust grill 520 .

Therefore, according to the present embodiment, there is an advantage in that a separate fixing means for fixing the exhaust grill 520 to the inner frame 501 is unnecessary.

The outer frame 540 may support the exhaust grill 520 . The outer frame 540 may be fixed to the exhaust grill 520 by, for example, fusion bonding while in contact with the lower surface of the exhaust grill 520 . However, it should be noted that there is no limitation on the fixing method of the exhaust grill 520 and the outer frame 540 in the present invention.

In order for the outer frame 540 to support the exhaust grill 520 , a seating groove 544 in which the exhaust grill 520 is seated may be formed in the outer frame 540 .

When the outer frame 540 is fixed to the exhaust grill 520, a filter accommodating space is formed between the outer frame 550 and the circumferential portion 503 of the inner frame, and the exhaust filter 560 can be accommodated in the filter accommodating space. In a state where the exhaust filter 560 is accommodated in the filter accommodating space, the exhaust filter 560 overlaps the air outlet 522 in a vertical direction.

The filter device 50 may further include an outer decorative member 550 coupled to the outer frame 540 . The outer decor member 550 may be coupled to the outer frame 540 while surrounding a portion of the circumference of the exhaust grill 520 . In addition, the outer decorative member 550 may surround the upper portion of the outer frame 540 . A seating surface 546 for seating a lower end of the outer decorative member 550 may be formed on an outer circumferential surface of the outer frame 540 .

One or more coupling protrusions 554 to be coupled to the outer frame 540 may be formed on the inner circumferential surface of the outer decor member 550, and the one or more coupling protrusions 554 may be formed on the outer circumferential surface of the outer frame 540. One or more coupling grooves 542 for accommodating 554 may be formed.

An anti-slip portion 552 may be provided on an outer circumferential surface of the outer decorative member 550 to prevent a hand from slipping when a user separates or couples the filter device 50 . The non-slip portion 552 may be, for example, a plurality of protrusions protruding from the outer surface of the outer decor member 550 .

A plurality of non-slip parts 552 may be spaced apart from each other in the circumferential direction of the outer decorative member 550 so as to effectively prevent the slipping of the user's hand.

The filter cover 570 may be formed in a ring shape, for example, and may include an opening 574 through which air passes.

The filter cover 570 may cover the exhaust filter 560 accommodated between the outer frame 540 and the inner frame 501 .

The filter cover 570 may support the lower surface of the outer frame 540 and the lower surface of the inner frame 501, and may be coupled to the outer frame 540 and the inner frame 501 by, for example, fusion bonding.

The filter device 50 may further include sealing members 530 and 580 for sealing the filter device 50 and the main body 2 in a state in which the filter device 50 is coupled to the main body 2.

10 is a cross-sectional view showing a state in which a filter mechanism is coupled to a main body according to an embodiment of the present invention.

9 and 10, the sealing members 530 and 580 may include an inner sealing member 530 (or a first sealing member) for preventing air in the flow guide 22 from leaking to the outside through a hook coupling hole 508 provided in the inner frame 501.

The inner sealing member 530 may be coupled to the inside of the circumferential portion 503 of the inner frame 501 .

Specifically, the sealing rib 504 may extend downward from the upper surface portion 502 of the inner frame 501 . The sealing rib 504 may be spaced apart from the circumferential portion 503 of the inner frame 501 . The sealing ribs 504 are continuously formed in the circumferential direction of the upper surface portion 501 .

Therefore, a space for accommodating the inner sealing member 530 is formed between the sealing rib 504 and the peripheral portion 503 of the inner frame 501, and a part of the inner sealing member 530 is fitted into the space.

In a state where the inner sealing member 530 is coupled to the inner frame 501, the inner sealing member 530 contacts the lower surface of the first portion 503a of the circumferential portion 503 and the inner circumferential surface of the second portion 503b and the lower surface of the sealing rib 504.

Also, when the filter device 50 is coupled to the main body 2 , the inner sealing member 530 is seated on an upper end of the flow guide 22 .

Therefore, according to the present invention, since the inner sealing member 230 is seated on the upper end of the flow guide 22 in a state of being in contact with the lower surface of the first portion 503a of the circumferential portion 503, the inner circumferential surface of the second portion 503b, and the lower surface of the sealing rib 504, air flowing through the flow guide 22 is prevented from flowing into the hook coupling hole 508.

In addition, air leakage through a gap between the outer circumferential surface of the flow guide 22 and the inner circumferential surface of the circumferential portion 503 of the inner frame 501 can be prevented by the inner sealing member 230 .

In order for the filter device 50 to be separated from the main body 2 , a gap may be formed between the outer surface of the filter device 50 and the inner circumferential surface of the second member 12 .

The sealing members 530 and 580 may further include an outer sealing member 580 (or a second sealing member) for preventing air in the second air passage 234 from flowing into a gap between the outer frame 540 and the second body 12 without passing through the exhaust filter 560.

The outer sealing member 580 may be coupled to an edge of the filter cover 570 . Although not limited, the outer sealing member 580 may be fitted to the filter cover 570 or integrally formed with the filter cover 570 by inserting injection.

A support surface 125 for supporting the outer sealing member 580 may be formed on an inner circumferential surface of the second member 12 . The support surface 125 may be formed by increasing the thickness of a portion of the second portion 12 .

When the filter device 50 is coupled to the main body 2 , the outer sealing member 580 may be seated on the support surface 125 .

Accordingly, air in the second air passage 234 may be prevented from flowing into a gap between the outer frame 540 and the inner circumferential surface of the second member 12 .

Meanwhile, when the filter mechanism 50 is coupled to the main body 2, the outer decorative member 550 is seated on the upper side of the second body 12 of the main body 2. Accordingly, the user can separate the filter device 50 from the main body 2 by rotating the filter device 50 in one direction while holding the outer decorative member 550 .

Also, in a state in which the filter mechanism 50 is coupled to the main body 2, a part of the exhaust filter 560 may be located inside the main body 2, and the other part may be located outside the main body 2.

According to the present invention, since a part of the filter device 50 protrudes to the outside of the main body 2, it is possible for the user to hold the filter device 50, and since the exhaust filter 560 can be positioned at the portion protruding out of the main body 2, the size of the exhaust filter 560 can be increased. Accordingly, an area of the exhaust filter 560 that can come into contact with air is increased, and thus air purification performance may be improved.

11 is a perspective view of a filter cover according to an embodiment of the present invention, FIG. 12 is a cross-sectional view showing an inner frame coupled to the filter cover of FIG. 11, FIG. 13 is a perspective view of a flow guide according to an embodiment of the present invention, and FIG.

10 to 14 , the filter cover 570 may include an inner body 571, an outer body 572 spaced apart from the inner body 571, and a connection body 573 connecting the inner body 571 and the outer body 572.

The inner body 571 and the outer body 572 may each be formed in a ring shape.

The connection body 573 may include one or more openings 574 through which air passes.

A plurality of frame support ribs 575 may be provided on the inner circumferential surface of the inner body 571 to support the lower surface 509 of the inner frame. The plurality of frame support ribs 575 may be spaced apart from each other in a circumferential direction of the inner body 571 .

A rib coupling part 577 for coupling with the flow guide 22 may be provided on an inner circumferential surface of the inner body 571 .

The inner body 571 may include an extension portion 576 so that the rib coupling portion 577 extends downwardly. The extension part 576 protrudes downward from the lower surface of the inner body 571, and the rib coupling part 577 may be provided in the extension part 576.

Accordingly, the rib coupling part 577 extends in the circumferential direction from the end of the frame support rib 575 and extends to be inclined downward.

The reason why the rib coupling portion 577 is inclined downward is to allow the filter device 50 to be coupled and released from the main body 2 in a rotational manner and to allow the filter device 50 to rise in the process of separating the filter device 50 from the main body 2.

When the filter device 50 rises in the process of being separated, the user can confirm that the filter device 50 is being separated.

When the filter device 50 is configured to be disengaged while the filter device 50 is rotated, since a rotational force must be applied to the filter device 50, even if the filter device 50 is pulled, it can be prevented from being separated from the main body 20. Accordingly, it can be prevented that the filter mechanism 50 is unintentionally separated from the main body 2 .

The rib coupling part 577 may include a slot 578 in which a fixing protrusion 229 of the flow guide 22, which will be described later, is accommodated. The slot 578 may be a groove or a hole.

The inner frame 501 may further include a contact portion 509a extending downward from the lower surface 509 of the inner frame 501 . The contact portion 509a may contact a side surface of the frame support rib 575 in a state in which the filter cover 570 and the inner frame 501 are coupled.

The inner frame 501 may include a recessed portion 509b formed by being recessed upward to form a rib accommodating portion 579 for accommodating the fixing rib 228 formed in the flow guide 22 .

In a state in which the inner frame 501 is coupled to the filter cover 570, the recessed portion 509b is disposed above the coupling rib 577 and spaced apart from the coupling rib 577.

At this time, the recessed portion 509b may be inclined so that the fixing rib 228 of the flow guide 22 can be accommodated in the rib accommodating portion 579 between the recessed portion 509b and the rib coupling portion 577 during rotation and descent of the filter mechanism 50.

Accordingly, the rib accommodating portion 579 also obliquely extends downward. The rib accommodating portion 579 may be understood as a space between the inner frame 501 and the filter cover 570 . That is, the fixing rib 228 of the flow guide 22 may be inserted between the inner frame 501 and the filter cover 570 .

The flow guide 22 may include a guide body 220 having upper and lower openings. The guide body 220 may include a passage forming wall 222 for forming the first air passage 232 through which the air discharged from the second cyclone part 130 flows.

The passage forming wall 222 may protrude from the guide body 222 in a radial direction.

At this time, the flow guide 22 may include a plurality of passage forming walls 222 spaced apart in the circumferential direction so that air can flow smoothly.

The suction motor 20 is located inside the flow guide 22. In order not to increase the size of the main body 2, the gap between the flow guide 22 and the suction motor 20 should not be large. However, if the gap between the flow guide 22 and the suction motor 20 is not large, there is a problem in that air flow performance deteriorates.

However, as in the present invention, when the passage forming wall 222 protrudes from the guide body 220, a sufficient cross-sectional area of the passage through which air can flow is secured by the passage forming wall 222, and air flow performance can be improved.

The flow path forming wall 222 is formed at a position spaced apart from the top of the flow guide 22 by a predetermined interval downward so that the flow path forming wall 222 does not interfere with the filter mechanism 50 while the upper portion of the flow guide 22 can be accommodated inside the inner frame 501.

Also, an outer diameter of the upper portion of the guide body 220 may be smaller than an inner diameter of the circumferential portion 503 of the inner frame 501 . Therefore, when the filter device 50 is coupled to the main body 2, the upper portion of the flow guide 22 is accommodated in the filter device 50 so that the inner sealing member 530 can be seated on the upper end of the flow guide 22.

According to the present invention, since a part of the flow guide 22 is accommodated inside the filter device 50, the increase in height of the cleaner 1 can be minimized.

A filter support 225 supporting a lower end of the pre-filter 29 may be provided on an inner circumferential surface of the guide body 220 . The filter support 225 may protrude from the inner circumferential surface of the guide body 220 .

A fastening part 226 for fastening with the motor housings 26 and 27 may be provided at a lower end of the guide body 220 .

The fastening part 226 of the guide body 220 may be seated on the upper motor housing 26 . In this state, the fastening member S1 may be fastened to the upper motor housing 26 after penetrating the fastening part 226 from above.

The fastening member S1 may also be fastened to the discharge guide 28 after penetrating the upper motor housing 26 and the lower motor housing 27 . According to this structure, since a small number can be assembled using fastening members, there is an advantage in that the structure and assembly method are easy.

The flow guide 22 may include a fixing rib 228 for coupling with the filter device 50 . The fixing rib 22 may be extended in a circumferential direction, but inclinedly, so that the height of the filter device 50 is varied during rotation of the filter device 50 . Also, a fixing protrusion 229 may be formed on a lower surface of the fixing rib 22 .

Meanwhile, reinforcing ribs 227 may be formed in the passage forming wall 222 . The flow guide 22 is spaced apart from the inner circumferential surface of the second body 12 to form the second air passage 234 .

The reinforcing rib 227 may extend from the passage forming wall 222 toward the second body 12 .

In this way, when the flow guide 22 is spaced apart from the inner circumferential surface of the second body 12, when an external force is applied from the outside of the second body 12, the second body 12 may be deformed toward the flow guide 22.

However, according to the present invention, as the reinforcing ribs 227 are formed on the flow path forming wall 222, even if an external force is applied to the second body 12, the second body 12 is in contact with the reinforcing rib 227, so that the deformation of the second body 12 can be limited.

Since the channel forming wall 222 protrudes from the guide body 220, when the reinforcing rib 227 is formed on the channel forming wall 222, the length of the reinforcing rib 227 can be reduced.

15 is a view showing a state before the filter device according to an embodiment of the present invention is coupled to the flow guide, and FIG. 16 is a view showing a state in which the filter device according to an embodiment of the present invention is coupled to the flow guide.

Referring to FIGS. 15 and 16, the coupling process of the filter mechanism 50 will be described.

In order to couple the filter device 50 to the main body 2, a lower portion of the filter device 50 is accommodated in the second body 12.

Then, the rib accommodating portion 579 of the filter device 50 and the fixing rib 228 may be aligned.

In this state, when the filter mechanism 50 is rotated, the fixing rib 228 is accommodated in the rib accommodating portion 579 . At this time, in order for the fixing rib 228 to be easily accommodated in the rib accommodating portion 579, the height of the rib accommodating portion 579 may be formed higher than the height of the fixing rib 228.

Since the fixing rib 228 extends obliquely, the filter device 50 is lowered by the fixing rib 228 during rotation of the filter device 50 .

When the fixing protrusion 229 is inserted into the slot 578 of the rib coupling part 577 while the fixing rib 228 is accommodated in the rib accommodating part 579, the filter mechanism 50 and the main body 2, that is, the coupling with the flow guide 22 is completed.

Meanwhile, in order to separate the filter device 50 from the main body 2, the filter device 50 is rotated in another direction. At this time, since the fixing rib 228 is inclined, the filter device 50 is elevated by the fixing rib 228 during rotation of the filter device 50 . Also, when the fixing rib 228 is removed from the rib accommodating part 579, the coupling between the filter mechanism 50 and the main body 2 is released.

In this state, when the filter device 50 is moved upward, the filter device 50 may be separated from the main body 2 .

17 is a view showing structures of a motor housing and a second body according to an embodiment of the present invention.

5 and 17 , the lower motor housing 27 may be integrally formed with the second body 12 .

A through hole 273 through which air flowing along the discharge guide 28 passes may be formed in the lower motor housing 27 .

The lower motor housing 27 may support the upper motor housing 26 . In this case, a first sealer 274 may be provided between the lower motor housing 27 and the upper motor housing 26 .

The lower motor housing 27 may further include an air guide 272 for guiding the air discharged from the suction motor 20 to the second air passage 234 .

The upper motor housing 27 may support the flow guide 22 . A second sealer 274 may be provided between the upper motor housing 27 and the flow guide 22 .

A through hole 262 through which air passing through the through hole 273 of the lower motor housing 27 passes may also be formed in the upper motor housing 26 .

18 is a longitudinal cross-sectional view showing air flow in the cleaner according to an embodiment of the present invention, and FIG. 19 is a cross-sectional view showing air flow in the cleaner according to an embodiment of the present invention.

With reference to FIGS. 17 to 19 , air flow in the vacuum cleaner 1 will be described.

Air and dust sucked through the suction part 5 by the operation of the suction motor 20 flow along the inner circumferential surface of the first cyclone part 110 and are separated from each other.

The dust separated from the air flows downward and is stored in the first dust storage unit 121 . Air separated from dust flows into the second cyclone part 130 . The air flowing into the second cyclone part 130 is separated from dust again.

Dust separated from air in the second cyclone unit 130 flows downward and is stored in the second dust storage unit 123 . On the other hand, air separated from dust in the second cyclone part 130 is discharged from the second cyclone part 130 and rises toward the suction motor 20 .

The air discharged from the second cyclone unit 130 flows along the discharge guide 28, passes through the through hole 273 of the lower motor housing 27, and then rises along the first air flow path 232 in the flow guide 22. Also, the air in the first air passage 232 passes through the pre-filter 29 .

Air passing through the pre-filter 29 passes through the suction motor 20 in the upper motor housing 27 . Air is discharged to the lower motor housing 28 after flowing inside the suction motor 20 by the impeller 200 . Also, the air discharged to the lower motor housing 28 is changed in direction by the air guide 272 and flows into the second air passage 234 .

The air flowing into the second air passage 234 passes through the exhaust filter 560 and then is discharged to the outside through the air outlet 522 .

According to the present invention, the passage through which the air flows is formed only in the main body 2 and not formed in the handle part 3. Therefore, when the handle part 3 is coupled to the main body 2, a structure for sealing the boundary between the handle part 3 and the main body 2 is unnecessary. Therefore, the structure for coupling the handle portion 3 to the main body 2 is simplified, and there is an advantage in that the coupling is easy.
