Abstract

A cleaner which has a main body that forms an external shape, a dust container that is separably combined with the main body and stores dust separated from air, a dust container cover that is configured to open and close the dust container, a handle unit that is disposed behind the dust container, and an operating member that is configured to provide operation force to the dust container cover by moving in a first direction and to release a holding mechanism for preventing separation of the dust container from the main body by moving in a second direction opposite to the first direction.

First claim

What is claimed is:

1. A cleaner comprising:
a first body that has a first side providing a first cyclone unit and a second side providing a dust container storing dust separated from the first cyclone unit;
a second cyclone unit configured to separate dust from air discharged from the first cyclone unit and at least a portion of which is located in the first body;
a second body that includes a suction motor configured to generate suction force and that is located opposite to the dust container based on the first cyclone unit; and
a filter unit that is separably combined with the second body and that has an air exit through which air passing through the suction motor is discharged,
wherein a portion of the filter unit is located outside the second body based on the filter unit being combined with the second body, and
wherein the first body is separated from the second cyclone unit in a direction parallel to an axis of cyclonic flow of the first cyclone unit in a state in which the second body and the second cyclone unit are connected.

2. The cleaner of claim 1 ,
wherein the axis of cyclonic flow of the first cyclone unit is disposed to pass through the suction motor.

3. The cleaner of claim 1 , further comprising:
a dust container cover configured to cover the dust container,
wherein the first body is separated together with the dust container cover.

4. The cleaner of claim 1 ,
wherein the first body is separated in a direction parallel to an axis of the suction motor.

5. The cleaner of claim 1 , further comprising:
a filter located in the first body, and
a dust storage guide connected to a lower side of the filter,
wherein the first body is separated in a state in which the filter and the dust storage guide are connected to the second cyclone unit.

6. The cleaner of claim 1 ,
wherein the dust container, the second cyclone unit, and the suction motor are sequentially arranged in an extending direction of the axis of cyclonic flow of the first cyclone unit.

7. The cleaner of claim 1 ,
wherein the axis of cyclonic flow of the first cyclone unit extends vertically.

8. A cleaner comprising:
a main body that has (i) a first body which has a first side providing a first cyclone unit configured to separate dust and a second side providing a dust container configured to store the dust separated from the first cyclone unit and (ii) a second body including a suction motor configured to generate suction force is received;
a handle unit connected to the main body;
a second cyclone unit configured to separate dust from air discharged from the first cyclone unit; and
a filter unit separably combined with the main body and having an air exit through which air passing through the suction motor is discharged,
wherein a portion of the filter unit is located outside the second body based on the filter unit being coupled to the second body, and
wherein the first body is separated from the second cyclone unit in a direction parallel to an axis of cyclonic flow of the first cyclone unit in a state in which the second body and the second cyclone unit are connected.

9. The cleaner of claim 1 or 8 ,
wherein the suction motor includes a rotating impeller and a shaft connected to the impeller,
wherein the shaft includes a first end and a second end located on an opposite side to the first end,
wherein the impeller is connected to a side of the first end of the shaft, and
wherein the second end is disposed between the impeller and the second cyclone unit based on the impeller being connected to the side of the first end.

10. The cleaner of claim 9 ,
wherein a rotational axis of the impeller passes through the first body.

11. The cleaner of claim 10 ,
wherein the rotational axis of the impeller and the axis of cyclonic flow of the first cyclone unit are parallel to each other.

12. The cleaner of claim 8 , further comprising:
a dust container cover disposed at a bottom of the dust container; and
an operating member configured to open and close the dust container cover,
wherein the dust container is separated from the second body based on an operation of the operating member.

13. The cleaner of claim 12 , wherein the operating member is coupled to the handle unit.

14. The cleaner of claim 12 , wherein the dust container cover is turned to open the dust container based on the operating member being operated in a first direction.

15. The cleaner of claim 14 , wherein the dust container cover is turned to close the dust container based on the operating member being operated in a second direction that is opposite to the first direction.

16. The cleaner of claim 12 ,
wherein the first body is separated from the main body based on the dust container cover closing the dust container.

17. The cleaner of claim 8 ,
wherein the axis of cyclonic flow of the first cyclone unit extends vertically.
