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.

Claims (29)

1. A cleaner comprising:

a suction part configured to suction air;

a main body comprising:

a body comprising a cyclone part configured to separate dust from the suctioned air and a dust container configured to store the separated dust, and

a body cover configured to open or close a lower portion of the body;

a filter part disposed in the body and configured to filter the air which has been separated from the dust;

a movable part configured to move between an outer portion of the filter part and an inner circumference surface of the body;

a manipulation part configured to move the movable part;

a transfer part connecting the movable part to the manipulation part;

an elastic member configured to elastically support the manipulation part; and

a supporting bar entirely disposed outside the dust container and coupled to the manipulation part to guide a movement of the manipulation part.

2. The cleaner of claim 1 , wherein the elastic member supports the manipulation part at a position which is horizontally spaced apart from the transfer part.

3. The cleaner of claim 1 , wherein, at a manipulation standby position of the manipulation part, a length of the elastic member is longer than a length of the transfer part.

4. The cleaner of claim 1 , wherein the elastic member is a coil spring, and

wherein the supporting bar is disposed within the coil spring.

5. The cleaner of claim 4 , further comprising:

an extension body extending downward from the manipulation part and surrounding the elastic member; and

a cover body supporting a lower portion of the elastic member and extending from the body to surround the lower portion of the elastic member.

6. The cleaner of claim 5 , wherein, at a manipulation standby position of the manipulation part, a portion of the extension body is disposed to horizontally overlap the cover body.

7. The cleaner of claim 6 , wherein a portion of the extension body is disposed within the cover body.

8. The cleaner of claim 4 , further comprising a stopper extending from the body and contacting the manipulation part at a manipulation standby position of the manipulation part.

9. The cleaner of claim 8 , wherein the supporting bar passes through the manipulation part and is coupled to the stopper.

10. The cleaner of claim 1 , further comprising a handle part coupled to an outer portion of the body, the handle part comprising a handle body,

wherein the transfer part is covered by the handle body, and

wherein the elastic member is disposed outside the handle body.

11. The cleaner of claim 1 , wherein the cyclone part comprises a first cyclone part configured to separate dust from the suctioned air, and a second cyclone part configured to separate dust from air discharged from the first cyclone part, and

wherein the supporting bar is disposed outside the second cyclone part.

12. The cleaner of claim 11 , wherein the elastic member is disposed outside the second cyclone part.

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