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 formed in a cylindrical shape, although not limited thereto.

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 located 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 . That is, the first body 10 includes a first cyclone part 110 and a dust container 120 . In this case, a part or all of the first body 10 may be transparent or translucent so that the user can visually check the amount of dust stored in the dust bin.

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 may open and close the first body 10 by a rotational motion. A button 18 for operating the rotation of the body cover 16 may be provided on the first body 10 .

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

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 an air outlet of the second cyclone unit 130 .

To this end, the 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 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, A passage between the dust separator 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 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 located 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 is reduced. This has the advantage of 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 portion of the suction motor 20 and a lower motor housing 27 covering a lower portion of the suction motor 20. there is. 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 .

Therefore, the inner circumferential surface of the flow guide 22 and the outer circumferential surface of the upper motor housing 26 form the 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 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 through the second air passage ( 234) and then 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 60 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, based on the handle 30, the heavy suction motor 20 is located in front of the handle 30, and the heavy battery 40 is positioned on the handle 30. Since it is located in the lower part, 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 includes a first extension 310 that extends vertically and can be held by a user, and a second extension extending from an upper side of the first extension 310 toward the suction motor 20. A portion 320 may be included. At least a part of the second extension part 320 may extend in a horizontal direction.

In the present invention, the first extension part 310 is a part that the user can hold (a part that the user's palm can contact) and can also be referred to as a grip part.

The first extension part 310 is provided to prevent the user's hand from moving in the longitudinal direction of the first extension part 310 (vertical direction in FIG. 2) while holding the first extension part 310. A movement limiting unit 312 may be provided. The movement limiting part 312 may extend toward the main body 2 from the first extension part 310 .

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 of the fingers are positioned above the movement limiting part 312 and other fingers are positioned 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 the user's wrist, the longitudinal axis A1 of the suction part 5 is substantially the same as the extending direction of the user's arm in a state where the user's arm is extended. can be confused with 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 . A control command of the suction motor 20 may be input through the manipulation unit 326 . For example, an on command and an off command of the suction motor 20 may be input using the control unit 326 . In addition, the strength of the suction force of the suction motor 20 may be adjusted in a state in which the suction motor 20 is turned on 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 326 may be positioned higher than the movement limiting unit 312 . Accordingly, the user can easily manipulate the manipulation unit 326 with a thumb while holding the first extension part 310 .

In addition, since the control unit 326 is positioned away from the first extension 310, when cleaning is performed while holding the first extension 310, the control unit 326 is unintentionally damaged. can be prevented from being manipulated.

The battery housing 60 may be located below the first extension part 310 .

The battery 40 may be detachably accommodated in the battery housing 60 .

For example, the battery 40 may be inserted into the battery housing 60 from below the battery housing 60 .

The rear surface of the battery housing 60 and the rear surface of the first extension part 310 may form a continuous surface. Accordingly, the battery housing 60 and the first extension portion 310 may have a sense of unity.

In a state in which the battery 40 is accommodated in the battery housing 60, a lower surface of the battery 40 may be exposed to the outside. Therefore, when the cleaner 1 is placed on the floor, the battery 40 may be placed on the floor.

According to this structure, there is an advantage in that the battery 40 can be directly separated from the battery housing 60 .

In addition, since the lower surface of the battery 40 is exposed to the outside, the lower surface of the battery 40 can directly contact the air outside the vacuum cleaner 1, so that the cooling performance of the battery 40 can be improved. .

The battery housing 60 may include an outer housing 600 and an inner housing 610 . The inner housing 610 may be inserted into the lower side of the outer housing 600 .

The inner housing 610 may be fixed to at least one of the outer housing 600 and the first body 10 . Also, the battery 40 may be coupled to the inner housing 610 .

According to the present invention, since the inner housing 610 accommodates the battery 40 in a state inserted into the outer housing 600 and is coupled with the battery 40, the outer housing 600 is deformed or the outer housing 600 is deformed. Damage to the outer housing 600 may be prevented during the process of mounting and separating the battery 40 .

Of course, it is also possible to integrally form the inner housing 610 with the outer housing 600 without forming the inner housing 610 separately.

The inner housing 610 may include a pair of hinge coupling parts 620 to which the hinge 162 of the body cover 16 is coupled. The pair of hinge coupling parts 620 may be spaced apart from each other by a predetermined interval.

The inner housing 610 may further include a charging base connection terminal 628 for charging the battery 40 while the battery 40 is mounted in the inner housing 610 .

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 formed 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 device 50 may be detachably coupled to the second body 12 .

In a state in which the filter device 50 is coupled to the main body 2 , a part of the filter device 50 is located outside the second body 12 . 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 .
