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 including a suction opening, a cyclone part configured to separate dust, 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 in the housing and disposed such that at least a portion thereof faces the suction opening at the first position,
wherein the frame includes: a frame body disposed to surround an axis of a cyclone flow of the cyclone part, and
at least a portion of the frame body has an inclination varied in a circumferential direction to form an air flow path through which a portion of the air suctioned through the suction opening flows.

2. The cleaner of claim 1 , wherein the air flow path is formed on an upper side of the frame body, and another portion of the air suctioned through the suction opening flows to a lower side of the frame body.

3. The cleaner of claim 1 , wherein an inclination of at least a portion of the frame body with respect to a horizontal plane decreases in a direction away from the suction opening in a circumferential direction.

4. The cleaner of claim 3 , wherein the frame body includes a first portion and a second portion located farther from the suction opening than the first portion,
upper surfaces of the first portion and the second portion forms the air flow path, and
a height of the air flow path at the second portion is higher than a height of the air flow path at the first portion.

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

6. The cleaner of claim 4 , wherein an inclination angle of the second portion with respect to the horizontal plane is smaller than an inclination angle of the first portion with respect to the horizontal plane.

7. The cleaner of claim 4 , wherein the frame body includes an outer extension wall configured to connect the first portion and the second portion and configured to act as an outer wall of the air flow path and an inner extension wall inwardly spaced apart from the outer extension wall and configured to act as an inner wall of the air flow path.

8. The cleaner of claim 7 , wherein a height of the outer extension wall at the second portion is lower than a height of the outer extension wall at the first portion.

9. The cleaner of claim 4 , wherein the frame body further includes a third portion located on the opposite side of the first portion with respect to the second portion, and
the first portion is inclined in a direction toward the axis of the cyclone flow from the upper side to the lower side, and the third portion is inclined in a direction away from the axis of the cyclone flow from the upper side to the lower side.

10. The cleaner of claim 9 , wherein a radius of a portion of the third portion with respect to the center of the frame body is smaller than a radius of the first portion.

11. The cleaner of claim 4 , wherein the frame body further includes a fourth portion located on the opposite side of the second portion with respect to the first portion, and
an inclination angle of the fourth portion with respect to the horizontal plane is greater than the inclination angle of the first portion.

12. The cleaner of claim 11 , wherein a radius of a portion of the fourth portion with respect to the center of the frame body is smaller than a radius of the first portion.

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

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

15. 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.

16. The cleaner of claim 15 , 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.
