Cleaner {Cleaner}

The present invention relates to a cleaner.

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

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

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

A handheld vacuum cleaner is disclosed in Korean Patent Registration No. 10-1127088 (registration date 2012.03.08.), which is a prior document.

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

In addition, the airflow generator is located in the motor housing and has a motor and fan assembly. In addition, 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, the filter may accumulate dust, and if the filter is not cleaned, the dust accumulated in the filter acts as a flow resistance, and thus there is a problem that the suction performance is deteriorated.

However, in the case of the prior literature, since the pre-motor filter is located between the airflow generator and the centrifugal separator, the post-motor filter is surrounded by the outer housing, so the product must be disassembled to access the filter. have.

In addition, since there is a structure for guiding air discharged from the centrifugal separator to the motor side and a structure for guiding air passing through the motor to a post-motor filter, the number of parts increases and the structure is complicated.

An object of the present invention is to provide a vacuum cleaner having a simple structure and a reduced number of parts since one flow guide forms the suction flow path and the exhaust flow path of the suction motor.

In addition, an object of the present invention is to provide a vacuum cleaner capable of ensuring the width of the air passage for flowing to the suction motor while the product is compact.

In addition, it is an object of the present invention to provide a cleaner that can be limited deformation of the body forming the appearance.

Further, an object of the present invention is to provide a vacuum cleaner capable of separating a filter mechanism and a pre-filter.

The cleaner according to one aspect includes: a suction unit; A first cyclone unit separating dust from the air sucked through the suction unit; A second cyclone unit separating dust from air discharged from the first cyclone unit; A suction motor including an impeller rotated to suck air through the suction unit; A motor housing disposed to surround the impeller; A pre-filter surrounding the impeller and the motor housing and filtering air discharged from the second cyclone unit; And a filter mechanism that filters air discharged from the intake motor and has a filter disposed around the pre-filter.

The outer diameter of the filter may be larger than the outer diameter of the pre-filter.

The motor housing may include a filter support for supporting the pre-filter.

When the filter mechanism is separated in a direction away from the suction motor, the pre-filter may be exposed to the outside.

The suction motor may further include a body including an opening, and the pre-filter may be accommodated into the body through the opening.

Further comprising a dust container for storing the dust discharged from the first cyclone unit and the second cyclone unit, the axis of the cyclone flow of the first cyclone unit is vertically arranged and the dust container is located at the lower side of the suction motor. In a position to be positioned, the suction motor may be located above the second cyclone unit.

The impeller may be located on the upper side of the suction motor.

According to the proposed invention, since the inner circumferential surface of the flow guide forms a suction flow path and the outer circumferential surface of the flow guide forms an exhaust flow path, it is to provide a cleaner with a simple structure.

Further, according to the present invention, since the flow path forming wall forming the first air flow path in the flow guide protrudes outward, the width of the first air flow path for flowing to the suction motor is secured, and air flow performance can be improved.

Further, according to the present invention, as the reinforcing rib is provided on the flow path forming wall, it is possible to prevent the body from being deformed toward the flow path forming wall.

In addition, according to the present invention, since the filter mechanism can be separated from the body, there is an advantage that the filter can be cleaned.

In addition, according to the present invention, since the suction motor is positioned so that the impeller is located at the upper portion of the suction motor, the pre-filter can cover the upper portion of the suction motor, so that when the filter mechanism is separated, it can be separated to the upper side of the pre-filter. .

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 intermediate member.

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

In addition, each of the first body 10 and the second body 12 has an upper side and a lower side open. That is, each of the bodies 10 and 12 may include an upper opening and a lower opening.

In addition, the suction part 5 may be coupled to the body 2 such that the central part of the suction part 5 is roughly located at the boundary between the first body 10 and the second body 12. .

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

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

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

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

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

As another example, it is possible that the dust separation unit has a single cyclone portion, and in this case, the axis of the cyclone flow may extend in the vertical direction.

The first body 10 serves as a dust bin for storing dust separated from the cyclone units 110 and 130.

The 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 may open and close the first body 10 by a rotation operation.

At least a portion of the second cyclone unit 130 may be located in the first body 10.

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

The dust storage guide 124 includes a first dust storage unit 121 in which dust separated from the first cyclone unit 110 is stored in the space inside the first body 10, and the second cyclone. The dust separated from the unit 130 may be divided into a second dust storage unit 123.

The inner space of the dust storage guide 124 is the second dust storage unit 123, and a 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 power and a battery 40 for supplying power to the suction motor 20.

The suction motor 20 may be located in the second body 12. And, at least a portion of the suction motor 20 may be located above the dust separation unit. Therefore, the suction motor 20 is located above the first body 10.

The suction motor 20 may communicate with an outlet of the second cyclone unit 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 communicating with the discharge guide 28.

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

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

Therefore, the axis of the cyclone flow of the dust separation unit may pass through the suction motor 20.

When the suction motor 20 is positioned above the second cyclone unit 130, air discharged from the second cyclone unit 130 can flow directly to the suction motor 20 side. The flow path between the dust separation unit and the suction motor 20 may be minimized.

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

In addition, the suction motor 20 may be disposed such that the impeller 200 is positioned above the suction motor 20. In this case, air may flow from the upper side to the lower side of the suction motor 20 by the impeller 200.

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

According to the present invention, the air discharged from the dust separation unit, that is, the air discharged upward from the second cyclone unit 130 decreases a path through which the suction motor 20 flows, and a change in the direction of air decreases. It has the advantage of reducing the flow loss of air.

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

The cleaner 1 may further include an upper motor housing 26 covering the upper part of the suction motor 20 and a lower motor housing 27 covering the lower part of the suction motor 20. . The suction motor 20 is accommodated in each of the motor housings 26, and the flow guide 22 may be arranged 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. Also, 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 a first air flow path 232, and the outer circumferential surface of the flow guide 22 and the inner circumferential surface of the second body 12 Forms a second air flow path 234.

The first air flow passage 232 serves as an intake flow passage, and the second air flow passage 234 serves as an exhaust flow passage.

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 is the second air passage ( 234) and then discharged to the outside. Therefore, the second air passage 234 serves as an exhaust passage.

The handle part 3 may include a handle 30 for gripping a user and a battery housing 410 disposed under the handle 30.

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

When defining the direction, the direction in which the suction part 5 is located in the cleaner 1 based on the suction motor 20 is forward, and the direction in which the handle 30 is located is backward.

The battery 40 may be located behind the first body 10. Therefore, the suction motor 20 and the battery 40 are disposed so as not to overlap in the vertical direction, and the arrangement height may also be differently arranged.

According to the present invention, based on the handle 30, the heavy suction motor 20 is located in front of the handle 30, the heavy battery 40 is the handle 30 of the handle 30 Since it is located at the bottom, the weight of the cleaner 1 is evenly distributed throughout. When the user grasps the handle 30 and cleans it, it can be prevented that an excessive force is applied to the user's wrist. That is, since the heavy components are distributed and arranged at the front and rear of the cleaner 1, they are arranged at different heights, so that the center of gravity of the cleaner 1 can be prevented from being tilted to either 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 configuration above the handle 30. That is, the upper surface of the handle 30 forms a partial appearance of the upper surface of the cleaner 1.

Accordingly, in the process of holding and using the handle 30, one configuration of the cleaner 1 may be prevented from contacting the user's arm.

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

The first extension portion 310 to prevent a user from moving the hand in the longitudinal direction of the first extension portion 310 (up and down direction in FIG. 2) while the user holds the first extension portion 310. A movement limiting part 312 may be provided. 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 the state where the first extension part 310 is gripped, some fingers are positioned above the movement limiting part 312 and the rest of the fingers are located below the movement limiting part 312.

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

According to this arrangement, in the state where the user grips the first extension portion 310, the longitudinal axis A1 of the suction portion 5 may pass the user's wrist.

When the longitudinal axis A1 of the suction part 5 passes the user's wrist, the longitudinal axis A1 of the suction part 5 in a state in which the user's arm is extended is substantially equal to the extending direction of the user's arm. Can be side by side. Therefore, in this state, the user has the advantage of minimizing the force of the user required when pushing or pulling the cleaner 1 while holding the handle 30.

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

The operation unit 326 may be arranged to face the user. The manipulation unit 326 based on the handle 30 may be located on the opposite side of the movement limiting unit 312.

The operation unit 316 is positioned higher than the movement limiting unit 312. Therefore, the user can easily operate the manipulation unit 326 with the thumb while holding the first extension unit 310.

In addition, since the operation unit 326 is positioned at a position away from the first extension unit 310, when the cleaning is performed while the first extension unit 310 is held, the operation unit 326 is unintentional. Can be prevented from being manipulated.

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

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

The battery housing 410 may be located under the first extension portion 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 portion 310 may form a continuous surface. Therefore, the battery housing 410 and the first extension portion 310 may have a sense of unity.

Meanwhile, referring to FIG. 3, the cleaner 1 may further include a filter mechanism 50 having an air outlet 522 through which air passing through the suction motor 20 is discharged. The air outlet 522 may include, for example, a plurality of openings, and the plurality of openings may be arranged in a circumferential direction. Accordingly, 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 body 2. That is, the filter mechanism 50 may be detachably coupled to the second body 12.

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

The height of the body 2 may be substantially the same as the height of the handle 30. Therefore, the filter mechanism 50 protrudes upward of the main body 2, and the user can easily separate the filter mechanism 50 while the user holds the filter mechanism 50.

The air outlet 522 is positioned above the filter mechanism 50 while the filter mechanism 50 is coupled to the body 2. Therefore, the air discharged from the suction motor 20 is discharged upwards of 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 to the user.

The main body 2 may further include a pre-filter 29 for filtering air flowing into the suction motor 20. The pre-filter 29 can be located in 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.

The filter mechanism 50 may press the pre-filter 29 to prevent the pre-filter 29 from moving while the filter mechanism 50 is mounted on the main body 2.

For example, the filter mechanism 50 may press the pre-filter 29 downward. Therefore, according to the present invention, there is an advantage that a structure for fixing the pre-filter 29 is unnecessary.

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

For example, the filter mechanism 50 may be separated above the main body 2.

Since the impeller 200 is disposed to be positioned above the suction motor 20, the pre-filter 29 may be arranged to surround the upper motor housing 26 to cover the impeller 200.

Accordingly, the pre-filter 29 may be exposed to the outside while the filter mechanism 50 is separated from the main body 2, and thus the pre-filter 29 is detachable.

The pre-filter 29 may include a handle 29a. The user can remove 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 a filter 560 for filtering air discharged from the suction motor 20 and a filter frame supporting the filter 560.

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

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

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

Also, at least a portion of the pre-filter 29 may be accommodated in an area formed by the filter 560. That is, the filter 560 surrounds the pre-filter 29.

The filter frame may be coupled to the flow guide 22 in a state 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.

The outer circumferential surface of the inner frame 501 and the inner circumferential surface of the outer frame 540 are spaced apart, and the filter 560 may be positioned between the inner frame 501 and the outer frame 540.

A seating portion for seating the exhaust grill 520 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 506) may be formed.

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 may be seated on the seating portion 506. In addition, the inner diameter of the exhaust grill 520 may be the same as or larger than the outer diameter of the first portion 503a of the circumferential portion 503. In addition, the outer diameter of the seating portion 506 and the outer diameter of the second portion 503b may be larger than the inner diameter of the exhaust grill 520.

Accordingly, the exhaust grill 520 is the seating portion (with the first portion 503a of the inner surface 501 and the first portion 503a of the circumferential portion 503 penetrating the exhaust grill 520 ). 506).

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

A hook coupling hole 508 for coupling the hook 512 may be formed in the inner frame 501.

The hook coupling hole 508 may be formed in the first portion 503a of the peripheral 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 the vertical direction.

Therefore, when the hook 512 of the inner deco member 510 moves along the guide groove 507 and is aligned with the hook coupling hole 508, the hook 512 is inserted into the hook coupling hole 508. Can be.

The inner decor member 510 may be coupled to the inner frame 501 while the exhaust grill 520 is seated on the seating 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 for the hook 512 of the inner decor member 510 to move. The guide groove 524 may extend in the vertical direction.

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

The inner deco member 510 may be seated on an upper surface of the exhaust grill 520 while the inner deco member 510 is coupled to the inner frame 501.

Therefore, according to the present embodiment, there is an advantage 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 welding, for example, in a state in contact with the lower surface of the exhaust grill 520. However, in the present invention, it is revealed that there is no limitation in the method for fixing the exhaust grill 520 and the outer frame 540.

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.

One or more coupling grooves 542 may be formed to be accommodated.

An anti-slip portion 552 may be provided on an outer circumferential surface of the outer decoration member 550 to prevent a hand from slipping when a user separates or combines the filter mechanism 50. The anti-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 anti-slip portions 552 may be arranged to be spaced apart in the circumferential direction of the outer teco member 550 so that the user's hand is effectively prevented from sliding.

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

The filter cover 570 may cover the 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 the outer frame 540 and the inner frame 501, for example, by fusion to each other. Can be combined.

The filter mechanism 50 further includes sealing members 530 and 580 for sealing the filter mechanism 50 and the body 2 while the filter mechanism 50 is coupled to the body 2. can do.

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

9 and 10, the sealing member 530, 580, the air in the flow guide 22 is leaked to the outside through the hook coupling hole 508 provided in the inner frame 501 An inner sealing member 530 (or a first sealing member) for preventing may be included.

The inner sealing member 530 may be coupled to the inner 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 circumference 503 of the inner frame 501. The sealing rib 504 is 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 the It fits into the space.

When the inner sealing member 530 is coupled to the inner frame 501, the inner sealing member 530 is the lower surface of the first portion 503a of the circumferential portion 503, and the second portion 503b. It is in contact with the inner circumferential surface and the lower surface of the sealing rib 504.

Then, when the filter mechanism 50 is coupled to the body 2, the inner sealing member 530 is seated on the upper end of the flow guide 22.

Accordingly, according to the present invention, the inner sealing member 230 is in contact with the lower surface of the first portion 503a of the circumferential portion 503, the inner peripheral surface of the second portion 503b and the lower surface of the sealing rib 504 Since it is seated at the top of the flow guide 22 in one state, air flowing through the flow guide 22 is prevented from flowing into the hook coupling hole 508.

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

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

The sealing members (530, 580), the air of the second air flow path 234 is not flowing through the filter 560 without flowing through the gap between the outer frame 540 and the second body 12 An outer sealing member 580 (or a second sealing member) for preventing may be further included.

The outer sealing member 580 may be coupled to the rim 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 mechanism 50 is coupled to the body 2, the outer sealing member 580 may be seated on the support surface 125.

Therefore, it is possible to prevent the air in the second air passage 234 from flowing into the gap between the outer frame 540 and the inner circumferential surface of the second member 12.

On the other hand, when the filter mechanism 50 is coupled to the body 2, the outer deco member 550 is seated on the upper side of the second body 12 of the body (2). Accordingly, the user can separate the filter mechanism 50 from the body 2 by rotating the filter mechanism 50 in one direction while holding the outer deco member 550.

And, while the filter mechanism 50 is coupled to the main body 2, a part of the filter 560 may be located in 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 mechanism 50 protrudes to the outside of the body 2, it becomes possible for a user to grip the filter mechanism 50, and to the outside of the body 2 Since the filter 560 may be located even in the protruding portion, the size of the filter 560 may be increased. Therefore, the area of the filter 560 capable of contacting the air is increased, thereby improving air purification performance.

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, and FIG. 13 is a flow guide according to an embodiment of the present invention 14 is a plan view of a flow guide according to an embodiment of the present invention.

10 to 14, the filter cover 570 includes an inner body 571, an outer body 572 spaced apart from the inner body 571, and an inner body 571 and the outer body. A connection body 573 connecting 572 may be included.

Each of the inner body 571 and the outer body 572 may be formed in a ring shape.

The connecting body 573 may be provided with one or more openings 574 for air to pass through.

A plurality of frame support ribs 575 for supporting the lower surface 509 of the inner frame 501 may be provided on the inner circumferential surface of the inner body 571. The plurality of frame support ribs 575 may be disposed spaced apart in the circumferential direction of the inner body 571.

A rib coupling portion 577 for coupling with the flow guide 22 may be provided on the 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 may extend downwardly. The extension portion 576 protrudes downward from the lower surface of the inner body 571, and the rib coupling portion 577 may be provided in the extension portion 576.

Therefore, the rib coupling portion 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 that the filter mechanism 50 can be coupled to and released from the body 2 in a rotational manner, and the filter mechanism 50 is separated from the body 2. This is to make the filter mechanism 50 rise in the process.

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

When the filter mechanism 50 is configured to be disengaged in the process of rotating the filter mechanism 50, since the rotational force must be applied to the filter mechanism 50, even if the filter mechanism 50 is pulled, the main body ( 20) can be prevented from being separated. Therefore, it is possible to prevent the filter mechanism 50 from being unintentionally separated from the body 2.

The rib coupling portion 577 may include a slot 578 in which the fixing protrusion 229 of the flow guide 22 to 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 the side surface of the frame support rib 575 in a state where the filter cover 570 and the inner frame 501 are combined.

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

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

At this time, in the process of rotating and lowering the filter mechanism 50, the fixed rib 228 of the flow guide 22 is connected to the rib receiving portion 579 between the recessed portion 509b and the rib coupling portion 577. To be accommodated, the depression 509b may be formed to be inclined.

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

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

The flow path forming wall 222 may protrude radially from the guide body 222.

At this time, in order to allow the air to flow smoothly, the flow guide 22 may include a plurality of flow path forming walls 222 spaced apart in the circumferential direction.

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 that air flow performance is deteriorated.

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

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

In addition, the outer diameter of the upper portion of the guide body 220 may be formed to be smaller than the inner diameter of the circumferential portion 503 of the inner frame 501. Therefore, when the filter mechanism 50 is coupled to the body 2, the upper portion of the flow guide 22 is accommodated in the filter mechanism 50 so that the inner sealing member 530 is the flow guide 22 ).

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

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

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

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

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

The flow guide 22 may include a fixed rib 228 for engagement with the filter mechanism 50. The fixing rib 22 may be extended in the circumferential direction, but may be inclinedly extended so that the height of the filter mechanism 50 is variable in the rotation process of the filter mechanism 50. In addition, a fixing protrusion 229 may be formed on the lower surface of the fixing rib 22.

Meanwhile, a reinforcing rib 227 may be formed in the flow path 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 flow path 234.

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

Thus, 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 is the flow guide 22 ).

However, according to the present invention, as the reinforcing ribs 227 are formed in the flow path forming wall 222, even if an external force is applied to the second body 12, the second body 12 is reinforcing ribs 227 ), the deformation of the second body 12 may be restricted.

Since the flow path forming wall 222 protrudes from the guide body 220, when the reinforcing rib 227 is formed in the flow path forming wall 222, the length of the reinforcing rib 227 can be reduced. There is this.

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

15 and 16, a description will be given of a coupling process of the filter mechanism 50.

The lower part of the filter mechanism 50 is accommodated in the second body 12 in order to couple the filter mechanism 50 to the body 2.

Then, the rib receiving portion 579 of the filter mechanism 50 and the fixed rib 228 may be aligned.

When the filter mechanism 50 is rotated in this state, the fixed rib 228 is accommodated in the rib receiving portion 579. At this time, the height of the rib receiving portion 579 may be formed higher than the height of the fixed rib 228 so that the fixed rib 228 is easily accommodated in the rib receiving portion 579.

Since the fixed rib 228 extends obliquely, in the process of rotating the filter mechanism 50, the filter mechanism 50 is lowered by the fixed rib 228.

When the fixing rib 228 is inserted into the rib receiving portion 579, the fixing protrusion 229 is inserted into the slot 578 of the rib coupling portion 577, the filter mechanism 50 and the The coupling of the main body 2, that is, the coupling with the flow guide 22 is completed.

On the other hand, in order to separate the filter mechanism 50 from the main body 2, the filter mechanism 50 is rotated in the other direction. At this time, since the fixed rib 228 is formed to be inclined, the filter mechanism 50 is raised by the fixed rib 228 during the rotation of the filter mechanism 50. Then, when the fixed rib 228 is removed from the rib receiving portion 579, the coupling between the filter mechanism 50 and the body 2 is released.

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

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

The dust separated from the air in the second cyclone unit 130 flows downward and is stored in the second dust storage unit 123. On the other hand, the air separated from the dust in the second cyclone unit 130 is discharged from the second cyclone unit 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 first in the flow guide 22. It rises along the air passage 232. Then, the air of the first air passage 232 passes through the pre-filter 29.

The 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. Then, the air discharged to the lower motor housing 28 is switched by the air guide 272 to flow to the second air flow path 234.

Then, the air flowing through the second air passage 234 is discharged to the outside through the air outlet 522 after passing through the filter 560.
