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

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

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

The first body 10 and the second body 12 are opened upward and downward, respectively. That is, each of the bodies 10 and 12 may include an upper opening and a lower opening.

The suction unit 5 may be coupled to the main body 2 such that a central portion of the suction unit 5 is located at a boundary portion 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 unit 5. [

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

Air and dust sucked through the suction unit 5 are spirally moved along the inner circumferential surface of the first cyclone unit 110.

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

The dust separator may further include a second cyclone unit 130 for separating dust from air discharged from the first cyclone unit 110 again. At this time, the second cyclone unit 130 may be located inside the first cyclone unit 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, it is also possible that the dust separating portion has a single cyclone portion, and in this case, the axis of the cyclone flow can also extend in the vertical direction.

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

The main body 2 may further include a body cover 16 for opening and closing the lower side of the first body 10. The body cover 16 can open / close the first body 10 by rotating operation. The first body 10 may be provided with a button 18 for operating the body cover 16 to rotate.

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

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

The suction motor 20 may be located in the second body 12. [ At least a part of the suction motor 20 may be located above the dust separator. Accordingly, the suction motor 20 is positioned above the first body 10.

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

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

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 separating portion can pass through the suction motor 20. [

When the suction motor 20 is positioned above the second cyclone unit 130, the air discharged from the second cyclone unit 130 can flow directly toward the suction motor 20, The flow path between the dust separating portion and the suction motor 20 can be minimized.

The suction motor 20 may include a rotating impeller 200. The impeller 200 may be connected to the shaft 202. The shaft 202 is disposed so as to extend in the vertical direction.

The extension of the shaft 202 (which may be referred to as the rotation axis of the impeller 200) can 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 path of the air discharged from the dust separating unit, that is, the air discharged upward from the second cyclone unit 130 toward the suction motor 20 is reduced, and the directional change of the air is reduced And the flow loss of the air is reduced.

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

The vacuum 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 have. The suction motor 20 is accommodated in each of the motor housings 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. At least a portion of the flow guide 22 may be spaced apart from the second body 12.

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

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

The handle portion 3 may include a handle 30 for grasping the user and a battery housing 60 disposed below the handle 30.

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

The direction in which the suction unit 5 is positioned with respect to the suction motor 20 in the cleaner 1 is forward and the direction in which the handle 30 is positioned is with the rear.

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

The suction motor 20 having a heavy weight is positioned in front of the handle 30 and the battery 40 having a heavy weight is positioned on the upper side of the handle 30, So that the entire weight of the vacuum cleaner 1 is evenly distributed. When the user grasps the handle 30 and performs cleaning, it is possible to prevent the user from waving the wrist. In other words, since heavy components are distributed in front of and behind the cleaner 1, they are disposed at different heights, so that the center of gravity of the vacuum cleaner 1 can be prevented from leaning to one side.

The battery 40 is positioned below the handle 30 and the suction motor 20 is positioned in front of the handle 30 so that there is no configuration above the handle 30. That is, the upper surface of the handle 30 forms an outer surface of a part of the upper surface of the cleaner 1.

Therefore, in the course of using the handle 30, the structure of the vacuum cleaner 1 can be prevented from contacting the user's arm.

The handle 30 includes a first extension 310 extending in a vertical direction and capable of being held by a user, a second extension 310 extending from the upper side of the first extension 310 toward the suction motor 20, (320). At least a portion of the second extension 320 may extend in the horizontal direction.

In the present invention, the first extension part 310 may be referred to as a grip part, which is a part that can be held by the user (a part where the user's palm can touch).

In order to prevent the hand from moving in the longitudinal direction of the first extending portion 310 (in the vertical direction in FIG. 2) while the user holds the first extending portion 310, A movement restricting unit 312 may be provided. The movement restricting part 312 may extend from the first extension part 310 toward the suction part 5. [

The movement limiter 312 is spaced apart from the second extension 320. Accordingly, in a state where the first extension 310 is held, some of the fingers are positioned above the movement restricting portion 312 and the remaining fingers are positioned below the movement restricting portion 312.

For example, the movement restricting portion 312 may be positioned between the index finger and the stop finger.

According to this arrangement, the longitudinal axis A1 of the suction unit 5 can pass the wrist of the user while the user grasps the first extension 310. [

When the longitudinal axis A1 of the suction part 5 passes over the wrist of the user, the longitudinal axis A1 of the suction part 5 in the state where the user's arm is extended is substantially perpendicular to the extension direction of the user's arm, . Therefore, in this state, the user has the advantage that the force required by the user when the user holds the handle 30 and pushes or pulls the vacuum cleaner 1 is minimized.

The handle 30 may include an operating portion 390. For example, the operating portion 390 may be disposed on an inclined surface of the second extending portion 320. A control command of the suction motor 20 can be input through the operation unit 390. [ For example, the control unit 390 may be used to input an on command and an off command of the suction motor 20. Further, the intensity of the suction force of the suction motor 20 can be adjusted through the operation unit 390 in a state where the suction motor 20 is turned on.

The operating portion 390 may be disposed to face the user. The operating portion 390 may be positioned on the opposite side of the movement restricting portion 312 with respect to the handle 30.

The operation unit 390 may be positioned higher than the movement restricting unit 312. Accordingly, the user can easily operate the operating unit 390 with his / her thumb while holding the first extension 310.

Since the operating portion 390 is located at a position away from the first extending portion 310 when the first extending portion 310 is gripped, Can be prevented from being operated.

The battery housing 60 may be positioned below the first extension portion 310.

The battery 40 may be removably received 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 extending portion 310 may form a continuous surface. Therefore, the battery housing 60 and the first extending portion 310 can have a sense of unity.

The lower surface of the battery 40 may be exposed to the outside while the battery 40 is accommodated in the battery housing 60. Therefore, when the vacuum cleaner 1 is placed on the floor, the battery 40 can be placed on the floor.

According to this structure, the battery 40 can be separated from the battery housing 60 directly.

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 cleaner 1, so that the cooling performance of the battery 40 can be improved .

The battery housing 60 may further include a charging unit connection terminal 628 for charging the battery 40 when the battery 40 is mounted on the battery housing 60. When the vacuum cleaner 1 is placed on a charging stand (not shown), a terminal of the charging stand can contact the charging stand connection terminal 628.

The battery housing 60 may be provided with a battery connection terminal 670 to be connected to a battery terminal 490 provided in the battery 40 accommodated in the battery housing 60. The battery connection terminal 670 may be coupled to the battery terminal 490 through the upper side of the battery 40. [

3, the vacuum cleaner 1 may further include a filter mechanism 50 having an air outlet 522 through which the air passing through the suction motor 20 is discharged. The air outlet 522 may include a plurality of openings, for example, and the plurality of openings may be arranged in the circumferential direction. Thus, the air outlet 522 can be arranged in the form of a ring.

The filter mechanism (50) can 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 body (2). Therefore, 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 outside the main body 2.

The height of the main body 2 may be substantially the same as the height of the handle 30. Therefore, the filter mechanism 50 can protrude upward from the main body 2 and 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 in a state where the filter mechanism 50 is coupled to the main body 2. [ Therefore, the air discharged from the suction motor 20 is discharged to the upper side of the main body 2.

According to the present embodiment, in the process of cleaning using the cleaner 1, the air discharged from the air outlet 522 can be prevented from flowing to the user side.

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