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 frame configured to be movable between a first position and a second position, the frame being disposed such that at least a portion thereof faces the suction opening at the first position,
wherein the frame comprises a frame body arranged to surround an axis of a cyclone flow of the cyclone part, and
wherein an upper flow path configured to allow air to flow therethrough along the frame body is formed at an upper side of the frame body in the housing, and a lower flow path configured to allow air to flow therethrough along an inner circumferential surface of the cyclone part is provided at a lower side of the frame body.

2. The cleaner of claim 1 , further comprising a communication flow path configured to connecting the upper flow path and the lower flow path and located between the frame body and the housing.

3. The cleaner of claim 1 , wherein the frame body include a flow path body configured to form the upper flow path and having an inclination varied in a circumferential direction of the frame body.

4. The cleaner of claim 3 , wherein the flow path body includes a first portion inclined by a first angle with respect to a horizontal plane and a second portion extending from the first portion and inclined by a second angle smaller than the first angle with respect to the horizontal plane.

5. The cleaner of claim 4 , wherein a height of the upper flow path at the second portion is higher than a height of the upper flow path at the first portion.

6. The cleaner of claim 4 , wherein an upper end of the second portion is positioned lower than an upper end of the first portion.

7. The cleaner of claim 3 , wherein the frame body furthers include a guide body extending from the flow path body and configured to guide air or dust in the upper flow path to the lower flow path.

8. The cleaner of claim 7 , wherein at least a portion of the flow path body is inclined in a direction toward to the axis of the cyclone flow from an upper side to a lower side, and
the guide body is inclined in a direction away from the axis of the cyclone flow from the upper side to the lower side.

9. The cleaner of claim 7 , wherein a distance between a portion of the guide body and an inner circumferential surface of the cyclone part is greater than a distance between the flow path body and the inner circumferential surface of the cyclone part.

10. The cleaner of claim 7 , wherein the frame body further includes a first body extending from the flow path body and configured to guide air suctioned through the suction opening to the lower flow path.

11. The cleaner of claim 10 , wherein an inclination angle of the first body with respect to the horizontal plane is greater than an inclination angle of the flow path body.

12. The cleaner of claim 10 , wherein the first body is arranged to face the suction opening.

13. The cleaner of claim 1 , wherein the second position is a position lower than the first position.

14. The cleaner of claim 1 , further comprising an air guide configured to guide air discharged from the cyclone part, and
wherein the frame body is arranged to surround the air guide at the first position.

15. The cleaner of claim 14 , wherein the cyclone part comprises a first cyclone part and a second cyclone part configured to dust from air received from the first cyclone part, and
the guide air is configured to guide air discharged from the second cyclone part.
