Abstract

A vacuum cleaner including: a suctioning unit; a main body including a cyclone part for separating dust from suctioned air and a dust container for storing the separated dust, and a body cover for opening and closing the lower side of the body; a filter unit, disposed in the body, for filtering air separated from the dust; an actuating unit capable of moving in the body between the outside of the filter unit and the inner circumference surface of the body; an operating unit disposed outside the body which operates in order to move the actuating unit; a transmission unit penetrating the body and connecting the actuating unit with the operating unit; and an elastic member disposed outside the body which elastically supports the operating unit.

First claim

What is claimed is:

1. A cleaner comprising:
a main body including:
a suction part;
a handle part coupled to the main body, the handle part comprising a handle body;
a body comprising:
a first cyclone part configured to separate dust from air suctioned through the suction part;
a second cyclone part configured to separate dust from air discharged from the first cyclone part;
a dust container configured to store the dust separated by the first and second cyclone parts; and
a body cover configured to open or close a lower portion of the body; and
a filter part disposed in the body and configured to filter air that is separated from dust in the first cyclone part;
a movable part configured to move along a space between an outer portion of the filter part and an inner circumference surface of the body;
a manipulation part disposed outside the main body and configured to move the movable part, wherein the manipulation part is configured to be moved independently of the handle part;
a transfer part passing through the main body and coupled to the movable part to transfer a manipulation force of the manipulation part to the movable part;
an elastic member configured to provide an elastic force to the manipulation part; and
a supporting bar configured to guide a movement of the manipulation part, wherein a first portion of the supporting bar is disposed at a lateral side of the dust container and the filter part in a state in which a center axis of a cyclonic flow of the first cyclone part is arranged along a vertical direction and the body cover is positioned at a lower side of the first and second cyclone parts.

2. The cleaner of claim 1 , wherein the supporting bar is disposed at a lateral side of the second cyclone part.

3. The cleaner of claim 1 , wherein the supporting bar is disposed outside the second cyclone part.

4. The cleaner of claim 1 , wherein a second portion of the supporting bar is disposed lower than the filter part.

5. The cleaner of claim 1 , wherein the transfer part is spaced apart from the supporting bar in a horizontal direction and disposed outside the supporting bar.

6. The cleaner of claim 1 , wherein the supporting bar passes through the manipulation part.

7. The cleaner of claim 1 , wherein the manipulation part surrounds the supporting bar and moves along the supporting bar.

8. The cleaner of claim 1 , wherein the elastic member is disposed outside the dust container.

9. The cleaner of claim 1 , wherein the elastic member includes a coil spring.

10. The cleaner of claim 1 , further comprising a suction motor to generate suction force,
wherein at a manipulation standby position of the manipulation part, a portion of the manipulation part and a portion of the suction motor lie in a same plane.

11. The cleaner of claim 10 , wherein the suction motor is disposed at an upper side of the second cyclone part.

12. The cleaner of claim 1 , wherein at a manipulation standby position of the manipulation part, an upper end of the manipulation part is positioned higher than the second cyclone part.

13. The cleaner of claim 1 , wherein the movable part includes:
a frame to surround the filter part; and
a coupling part to which the transfer part is coupled, the coupling part extending from the frame in a horizontal direction.

14. The cleaner of claim 13 , wherein the frame includes an inclined surface about the vertical direction toward a cyclone flow axis of the first cyclone part, the vertical direction being perpendicular to the horizontal direction.

15. A cleaner comprising:
a first body comprising:
a first cyclone part configured to separate dust;
a second cyclone part configured to separate dust from air discharged from the first cyclone part; and
a dust container configured to store the dust separated by the first and second cyclone parts;
a second body disposed on the first body and including a suction motor configured to generate a suction force;
a suction part being configured to suction air due to the suction force generated by the suction motor;
a filter part disposed in the body and configured to filter air that is separated from dust in the first cyclone part;
a movable part configured to be moved in order to clean the filter part;
a manipulation part disposed outside the first body and configured to move the movable part, the manipulation part including a through hole;
a handle body configured to contact the manipulation part to guide movement of the manipulation part, wherein the manipulation part is configured to be moved independently of the handle body;
a transfer part passing through the first body and coupled to the movable part to transfer a manipulation force of the manipulation part to the movable part; and
a supporting bar extending through the through hole of the manipulation part to guide a movement of the manipulation part, wherein a portion of the supporting bar is positioned lower than the filter part in a state in which a center axis of a cyclonic flow of the first cyclone part is arranged along a vertical direction and the filter part is positioned at a lower side of the suction motor.

16. The cleaner of claim 15 , further comprising a handle part,
wherein the manipulation part includes:
a first part disposed within the handle part; and
a second part extending from the first part and disposed outside the handle part.

17. The cleaner of claim 16 , wherein the handle part includes a slot,
wherein the manipulation part further includes a neck part disposed in the slot of the handle part, and
wherein the neck part has a width less than a width of the first part and the second part.

18. The cleaner of claim 15 , wherein the movable part includes:
a cleaning part for cleaning the filter part;
a frame supporting an outer perimeter of the cleaning part; and
a core part supporting an inner perimeter of the cleaning part.

19. The cleaner of claim 18 , wherein the frame of the movable part includes:
a pressurization rib extending downwards from an outer body of the frame to pressurize the dust stored in the dust container; and
a connection part extending outward from the pressurization rib and for connecting the frame to the transfer part.

20. A cleaner comprising:
a main body including:
a suction part;
a handle part coupled to the main body, the handle part comprising a handle body;
a suction motor configured to generate suction force;
a body comprising: a first cyclone part configured to separate dust from air suctioned through the suction part;
a second cyclone part configured to separate dust from air discharged from the first cyclone part;
a dust container configured to store the dust separated by the first and second cyclone parts; and
a body cover configured to open or close a lower portion of the body; and
a filter part disposed in the body and configured to filter air that is separated from dust in the first cyclone part;
a movable part configured to move along a space between an outer portion of the filter part and an inner circumference surface of the body;
a manipulation part disposed outside the main body and configured to move the movable part, wherein the manipulation part is configured to be moved independently of the handle part;
a transfer part passing through the main body and coupled to the movable part to transfer a manipulation force of the manipulation part to the movable part;
an elastic member configured to provide an elastic force to the manipulation part; and
a supporting bar con
