Abstract

A cleaner includes a housing including a suction opening, a cyclone part configured to separate air and dust, and a dust bin configured to store dust separated from air in the cyclone part and a frame disposed to surround an axis of a cyclone flow of the cyclone part in the housing and configured to be movable between a first position and a second position in the housing, wherein the frame includes a first body disposed to face the suction opening at the first position and disposed to be inclined with respect to the axis of the cyclone flow, and an upper end of the first body is located to be the same as or higher than an upper end of the suction opening.

First claim

What is claimed is:

1. A cleaner comprising:
a housing comprising a suction opening, a cyclone part configured to separate dust from air introduced through the suction opening, and a dust bin configured to store dust separated at the cyclone part; and
a movable part configured to be movable between a first position and a second position inside the housing, the moveable part being disposed such that at least a portion thereof faces the suction opening at the first position,
wherein the movable part comprises a frame disposed to surround an axis of a cyclone flow of the cyclone part at the first position,
wherein the frame comprises a first body facing the suction opening at the first position and inclined at a first angle with respect to a horizontal plane and a second body extending from the first body and inclined at a second angle that is smaller than the first angle with respect to the horizontal plane,
wherein the second body forms an air flow path through which air introduced through the suction opening flows.

2. The cleaner of claim 1 , wherein a bottom surface of the second body forms a lower portion of the air flow path.

3. The cleaner of claim 2 , wherein the bottom surface of the second body is lowered in a direction away from the first body and increased in a direction toward the first body.

4. The cleaner of claim 1 , wherein a height of the air flow path increases in a direction away from the first body.

5. The cleaner of claim 1 , further comprising:
an extension wall extending upward from an outer end of the second body to form the air flow path.

6. The cleaner of claim 5 , wherein a height of an upper end of the extension wall is lowered in a direction away from the first body.

7. The cleaner of claim 1 , wherein the frame further comprises a third body extending in a circumferential direction from the second body and inclined at a third angle with respect to the horizontal plane.

8. The cleaner of claim 7 , wherein the first body is inclined upward in a direction away from the axis of the cyclone flow from a lower side of the first body to an upper side thereof, and
wherein the third body is inclined downward in a direction away from the axis of the cyclone flow from the upper side of the third body to the lower side thereof.

9. The cleaner of claim 8 , wherein an inclination angle of the second body with respect to the horizontal plane is varied in the circumferential direction, and
wherein the third angle is greater than an inclination angle at one point of the second body.

10. The cleaner of claim 8 , wherein the third body comprises an upper end and a lower end, the lower end of the third body being located outside the upper end with respect to a radial direction, and
wherein the lower end of the third body is located lower than the second body.

11. The cleaner of claim 10 , wherein the upper end of the third body is located above one point of the second body and located below another point of the second body.

12. The cleaner of claim 7 , wherein the frame further comprises a fourth body extending from the third body in the circumferential direction and inclined at a fourth angle with respect to the horizontal plane, and
wherein the fourth angle is greater than the third angle.

13. The cleaner of claim 12 , wherein the fourth body is coupled to the first body.

14. The cleaner of claim 13 , wherein a radius of an outer end of the fourth body with respect to a center of the frame is less than a radius of an outer end of the first body.

15. The cleaner of claim 12 , wherein a distance between the fourth body and an inner circumferential surface of the housing is greater than a distance between the first body and the inner circumferential surface of the housing.

16. The cleaner of claim 1 , wherein the frame comprises a third body extending from the second body, the third body configured to cause air or dust flowing through the air flow path to fall downward.

17. The cleaner of claim 16 , wherein a distance between one point of the third body and the inner circumferential surface of the housing is greater than a distance between the second body and the inner circumferential surface of the housing.

18. The cleaner of claim 16 , further comprising:
a fourth body extending from the third body,
wherein an inclination angle of the fourth body with respect to the horizontal plane is greater than an inclination angle of the third body, and
wherein a distance between one point of the fourth body and the inner circumferential surface of the housing is greater than a distance between the third body and the inner circumferential surface of the housing.

19. The cleaner of claim 1 , further comprising:
an air guide disposed in the housing,
wherein the frame is arranged to surround the air guide at the first position.

20. The cleaner of claim 19 , wherein the air guide comprises a guide wall disposed to surround the axis of the cyclone flow,
wherein the first body is in contact with the guide wall and at least a portion of the second body is spaced apart from the guide wall.

21. The cleaner of claim 20 , wherein the air flow path is located in a space formed between the guide wall and the second body.

22. The cleaner of claim 1 , further comprising:
a filter part disposed in the housing and configured to filter air separated from dust at the cyclone part,
wherein the movable part further comprises a cleaning part coupled to the frame, the cleaning part configured to clean the filter part when moving between the first position and the second position.
