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 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 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 .

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.

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 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 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 390 . For example, the control unit 390 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 390 . For example, an on command and an off command of the suction motor 20 may be input using the control unit 390 . 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 390 .

The control unit 390 may be disposed to face a user. Based on the handle 30 , the control unit 390 may be positioned on the opposite side of the movement limiting unit 312 .

The control unit 390 may be positioned higher than the movement limiting unit 312 . Accordingly, the user can easily manipulate the manipulation unit 390 with a thumb while holding the first extension part 310 .

In addition, since the operation unit 390 is located at a position away from the first extension 310, when cleaning is performed while holding the first extension 310, the operation unit 390 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 further include a charging base connection terminal 628 for charging the battery 40 while the battery 40 is mounted in the battery housing 60 .

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 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 .
