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 air and dust received through the suction opening, 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, the frame configured to be movable between a standby position and a compression position in the housing,
wherein the frame comprises a first body disposed to face the suction opening at the standby position, the first body disposed to be inclined with respect to the axis of the cyclone flow,
wherein a portion of the first body is located higher than a center of the suction opening at the standby position, and another portion of the first body is located lower than the center of the suction opening at the standby position, and
wherein an upper end of the first body is located at the same height or above an upper end of the suction opening,
wherein the standby position is an initial static position of the frame.

2. The cleaner of claim 1 , further comprising:
a guide wall disposed to surround the axis of the cyclone flow of the cyclone part in the housing, the guide wall configured to guide a flow of air, and
wherein the frame is configured to surround the guide wall at the standby position.

3. The cleaner of claim 2 , wherein the first body is in contact with the guide wall at the standby position, and
wherein a boundary portion between the upper end of the first body and the guide wall is located above the upper end of the suction opening.

4. The cleaner of claim 1 , wherein the first body is spaced apart from the suction opening, and at least a portion of the first body is inclined in a direction that is away from the suction opening.

5. The cleaner of claim 1 , further comprising:
a filter part configured to purify air separated from dust at the cyclone part and disposed to surround the axis of the cyclone flow; and
a cleaning part connected to a lower portion of the frame,
wherein at least a portion of the cleaning part is in alignment with the suction opening at the standby position.

6. The cleaner of claim 5 , further comprising:
a lower extending portion extending in a downward direction from the first body,
wherein the cleaning part comprises a depressed portion to accommodate the lower extending portion, and
wherein the lower extending portion is in alignment with the suction opening at the standby position.

7. The cleaner of claim 6 , wherein the lower extending portion is inclined with respect to the first body.

8. The cleaner of claim 6 , wherein a height of a portion of the cleaning part located below the lower extending portion is below a height of other portions of the cleaning part.

9. The cleaner of claim 5 , wherein the filter part comprises a mesh material portion allowing air to pass there through, and wherein an upper end of the mesh material portion is located below a lower end of the suction opening.

10. The cleaner of claim 9 , wherein the cleaning part comprises a contact end configured to contact the mesh material portion during the process of moving from the standby position to the compression position, and
wherein the contact end is located above the upper end of the mesh material portion at the standby position.

11. The cleaner of claim 10 , wherein the contact end is located closer to the lower end of the suction opening than to the upper end of the suction opening at the standby position.

12. The cleaner of claim 1 , wherein the frame further comprises a frame guide extending in a downward direction from an outer circumferential surface of the first body, the frame guide being aligned with the suction opening.

13. The cleaner of claim 12 , wherein the frame guide comprises a guide surface, and
wherein an extending line of the guide surface is parallel to an extending line extending in a tangential direction of the cyclone part.

14. The cleaner of claim 12 , further comprising:
a filter part configured to purify air separated from dust at the cyclone part and disposed to surround the axis of the cyclone flow; and
a cleaning part connected to a lower portion of the frame,
wherein the cleaning part comprises a contact end configured to contact the filter part during the process of moving from the standby position to the compression position, and
wherein a lower end of the frame guide is located below the contact end at the standby position.

15. The cleaner of claim 14 , wherein the contact end is located above a lower end of the suction opening at the standby position, and wherein the lower end of the frame guide is located at the same height as a height of a lower end of the suction opening or below the lower end of the suction opening.

16. A cleaner comprising:
a housing comprising a suction opening, a cyclone part configured to separate air and dust received through the suction opening, and a dust bin configured to store dust separated from the air at the cyclone part; and
a frame disposed to surround an axis of a cyclone flow of the cyclone part in the housing, the frame configured to be movable between a standby position and a compression position in the housing, the frame disposed such that at least a portion thereof faces the suction opening at the standby position,
wherein the frame comprises:
a first body configured to guide air received through the suction opening in a downward direction at the standby position;
a lower extending portion extending in a downward direction from a lower side of the first body; and
a frame guide extending horizontally from the first body, the frame guide configured to guide a horizontal flow of air received through the suction opening,
wherein an upper portion of the frame guide is located higher than a center of the suction opening at the standby position, and a lower portion of the frame guide is located lower than the center of the suction opening at the standby position,
wherein the standby position is an initial static position of the frame.

17. The cleaner of claim 16 , wherein the frame guide extends in a downward direction from the first body, and wherein a lower end of the frame guide is located below a lower end of the lower extending portion at the standby position.

18. The cleaner of claim 16 , wherein the first body is inclined in a direction that is away from the suction opening from an upper side to a lower side.

19. The cleaner of claim 16 , wherein an upper end of the first body is located at a height that is the same as or above an upper end of the suction opening at the standby position.

20. A cleaner comprising:
a housing including a suction opening, a cyclone part configured to separate air and dust received through the suction opening, and a dust bin configured to store dust separated from the air at the cyclone part; and
a frame disposed to surround an axis of a cyclone flow of the cyclone part in the housing, the frame configured to be movable between a standby position and a compression position in the housing, the frame disposed such that at least a portion thereof faces the suction opening at the standby position,
wherein the frame comprises a first body in which at least a portion thereof is inclined in a direction that is away from the suction opening from an upper side to a lower side to guide air received through the suction opening in a downward direction at the standby position,
wherein a portion of the first body is located higher
