Abstract

A vacuum cleaner is provided. The vacuum cleaner may include a dust separation device that separates dust and a dust container in which the dust separated in the dust separation device may be stored.

Claims

1. A vacuum cleaner, comprising:

a main body;

a dust separator removably mounted on the main body;

a cord reel chamber disposed within the main body, the cord reel chamber containing a cord reel around which a power cord is wound, the power cord being configured to supply power to the main body;

an exhaust filter device chamber disposed within the main body, the exhaust filter device chamber being configured to receive therein an exhaust filter device, the exhaust filter device filtering air that passes through a suction motor;

a connection passage that communicates the exhaust filter device chamber with the cord reel chamber; and

a suction motor chamber configured to receive the suction motor therein, wherein the exhaust filter device chamber is disposed downstream of the suction motor chamber and the cord reel chamber is disposed downstream of the exhaust filter device chamber, and wherein the cord reel chamber, the exhaust filter device chamber, and the suction motor chamber communicate, such that air exhausted from the dust separator flows into the main body, passes through the suction motor, then passes through the exhaust filter device chamber, and then at least a portion passes through the cord reel chamber.

2. The vacuum cleaner of claim 1, further comprising a cord reel lever disposed on the main body, configured to wound the power cord onto the cord reel.

3. The vacuum cleaner of claim 1, wherein the cord reel chamber is disposed below a mounting part of the main body, the mounting part being configured to receive the dust separator mounted thereon.

4. The vacuum cleaner of claim 3, wherein the exhaust filter device chamber is disposed below the cord reel chamber.

5. The vacuum cleaner of claim 4, wherein the suction motor chamber is disposed below the exhaust filter device chamber.

6. The vacuum cleaner of claim 5, wherein the exhaust filter device and the suction motor chamber communicate via an exhaust passage.

7. The vacuum cleaner of claim 1, wherein the exhaust filter device comprises:

a filter housing;

a filter body disposed in the filter housing; and

a filter disposed in and protected by the filter body.

8. The vacuum cleaner of claim 7, wherein the filter housing comprises:

an outer wall defining a filter body receiving space configured to receive the filter body therein; and

a cover part disposed at a front side of the outer wall.

9. The vacuum cleaner of claim 8, wherein the cover part is exposed at an outer wall of the main body and defines a portion of an outer appearance of the main body.

10. The vacuum cleaner of claim 8, wherein the cover part comprises a plurality of exhaust holes, through which air passes.

11. The vacuum cleaner of claim 8, wherein the filter housing further comprises a filter lever rotatably coupled to the cover part.

12. The vacuum cleaner of claim 11, wherein the filter lever comprises a hook configured to mate with a hook hanger disposed on an inner wall of the exhaust filter device chamber.

13. The vacuum cleaner of claim 11, further comprising an elastic member that elastically supports the filter lever.

14. The vacuum cleaner of claim 7, wherein the filter body comprises a top surface, an inner wall, and an outer wall, and a plurality of holes are provided in the top surface, through which air passes.

15. The vacuum cleaner of claim 14, wherein the outer wall surrounds and is spaced from the inner wall.

16. The vacuum cleaner of claim 15, wherein when the filter body is seated on the filter housing, the outer wall of the filter housing is disposed between the inner wall and the outer wall of the filter body.

17. The vacuum cleaner of claim 16, further comprising a plurality of guide ribs disposed on the top surface of the filter body.

18. The vacuum cleaner of claim 17, wherein the plurality of guide ribs extend in a front to rear direction of the exhaust filter device.

19. The vacuum cleaner of claim 1, wherein the vacuum cleaner comprises an upright type vacuum cleaner.

20. A vacuum cleaner, comprising:

a main body;

a dust separator removably mounted on the main body;

a cord reel chamber disposed within the main body, the cord reel chamber containing a cord reel around which a power cord is wound, the power cord being configured to supply power to the main body;

an exhaust filter device chamber disposed within the main body, the exhaust filter device chamber being configured to receive therein an exhaust filter device, the exhaust filter device filtering air that passes through a suction motor; and

a suction motor chamber configured to receive the suction motor therein, wherein the cord reel chamber, the exhaust filter device chamber, and the suction motor chamber communicate, such that air exhausted from the dust separator flows into the main body, passes through the suction motor, passes through the exhaust filter device chamber, and at least a portion passes through the cord reel chamber, and wherein the exhaust filter device is removably received within the exhaust filter device chamber, the exhaust filter device comprising;

a filter housing;

a filter body disposed in the filter housing;

a filter disposed in and protected by the filter body; and

a filter lever that selectively couples the exhaust filter device to the main body.
