Abstract

A vacuum cleaner is provided that includes a cleaner body; a dust separating apparatus fixed to the cleaner body; a first dust receptacle detachably attached to the cleaner body on a bottom portion of the dust separating apparatus to collect large particle dust; a second dust receptacle detachably attached to the cleaner body on a bottom portion of the first dust receptacle to collect fine particle dust; and a locking device having a first position in which the dust separating apparatus is closely contacted to the first and second dust receptacles, and a second position in which the dust separating apparatus is spaced apart from the first and second dust receptacles at a predetermined interval. The second dust receptacle is detached from the first dust receptacle at the second position, and is detached from the cleaner body after the first dust receptacle is disengaged from the cleaner body.

Claims

1. A vacuum cleaner, comprising:

a cleaner body;

a dust separating apparatus fixed to the cleaner body;

a first dust receptacle detachably attached to the cleaner body, the first dust receptacle being disposed on a bottom portion of the dust separating apparatus to collect large particle dust from the dust separating apparatus;

a second dust receptacle detachably attached to the cleaner body, the second dust receptacle being disposed on a bottom portion of the first dust receptacle to collect fine particle dust from the dust separating apparatus; and

a locking device comprising a first position in which the dust separating apparatus is closely contacted to the first and second dust receptacles, and a second position in which the dust separating apparatus is spaced apart from the first and second dust receptacles at a predetermined interval.

2. The vacuum cleaner of claim 1, wherein the second dust receptacle is detached from the first dust receptacle at the second position, and is detached from the cleaner body after the first dust receptacle is disengaged from the cleaner body.

3. The vacuum cleaner of claim 2, wherein the locking device comprises:

a slope way formed on the cleaner body to face a bottom surface of the second dust receptacle; and

a rotational handle that ascends and descends along the slope way to move the second dust receptacle upward or downward.

4. The vacuum cleaner of claim 3, wherein the rotational handle comprises:

a handle body;

a lever that protrudes from the handle body; and

a hook that protrudes on an upper portion of the lever.

5. The vacuum cleaner of claim 4, wherein at least one auxiliary slope way is formed inside the slope way to correspond to a portion of the handle body.

6. The vacuum cleaner of claim 5, wherein the handle body comprises:

an auxiliary sliding slope way that is formed to have a shape corresponding to the auxiliary slope way on a portion facing the auxiliary slope way.

7. The vacuum cleaner of claim 6, wherein the lever comprises a hook that protrudes towards the second dust receptacle, and the second dust receptacle comprises a hook groove that faces the hook,

wherein the hook is hooked with the hook groove at the first position, maintains connection between the second dust receptacle and the handle body while moving to the second position, and lowers the second dust receptacle.

8. The vacuum cleaner of claim 7, wherein the hook groove comprises:

an opening portion into or from which the hook is inserted or detached at the second position; and

a blocking member that prevents the hook from being detached from the opening portion when the hook moves to the first position.

9. The vacuum cleaner of claim 1, wherein the first dust receptacle is detached in the forward direction of the cleaner body, and the second dust receptacle is raised to a portion where the first dust receptacle is disposed, and is detached in the forward direction of the cleaner body.

10. The vacuum cleaner of claim 9, wherein the cleaner body comprises:

a guide rail that supports the first dust receptacle; and

a supporting portion that is formed on a portion corresponding to the guide rail of the first dust receptacle.

11. The vacuum cleaner of claim 10, wherein the cleaner body further comprises:

a first protruding unit that prevents the first dust receptacle from rotating; and

a second protruding unit that prevents the second dust receptacle from rotating.

12. The vacuum cleaner of claim 11, wherein the first dust receptacle comprises a guide groove engaged with the first protruding unit, and the second dust receptacle comprises a guide recess engaged with the second protruding unit.

13. The vacuum cleaner of claim 3, wherein the second dust receptacle comprises an air outlet on a bottom surface thereof.

14. The vacuum cleaner of claim 13, wherein the air outlet comprises:
