Abstract

Disclosed related to a vacuum cleaner comprising a cleaner body in which a dust collector mount part is formed; a dust collector attached and removed at the dust collector mount part, and having a dust storage part in the inside; at least one of the compressing member reducing the volume of the dust stored in the dust storage part as arranged in the dust storage part movably; a power transfer unit transferring the driving force to the compressing members from outside as connected with the compressing members; and a control unit deciding the amount of the dust stored in the dust storage unit.

Claims

1. A vacuum cleaner, comprising:

a main body including a suction motor that generates a suction power;

a dust separator that communicates with the suction motor and that separates dust and dirt from air;

a dust collector body configured to store dust separated from the dust separator;

at least one plate rotatably provided within the dust container and configured to compress dust stored in the dust collector body;

a transfer device comprising at least one gear connected to the at least one plate; and

a guide configured to transfer a driving force to the at least one plate.

2. The vacuum cleaner according to claim 1, wherein the at least one gear is connected to the at least one plate.

3. The vacuum cleaner according to claim 2, wherein the guide comprises a rotating shaft of the at least one plate, wherein a gear axle of the at least one gear is coupled to the rotating shaft, and wherein a horizontal section of the gear axle is non-circular in shape.

4. The vacuum cleaner according to claim 3, wherein the horizontal section of the gear axle is polygonal.

5. The vacuum cleaner according to claim 3, wherein the gear axle is inserted into the rotating shaft.

6. The vacuum cleaner according to claim 3, wherein the gear axle is coupled to the rotating shaft at a lower portion of the dust collector body.

7. The vacuum cleaner according to claim 2, wherein the guide is a coupling member coupled to the at least one plate and the at least one gear in a state in which the at least one gear is connected to the at least one plate.

8. The vacuum cleaner according to claim 2, wherein the dust collector body includes a cover configured to cover at least a portion of the gear.

9. The vacuum cleaner according to claim 2, further comprising a drive device that generates the driving force to rotate the at least one plate, wherein the at least one gear of the transfer device includes a driving gear connected to the drive device and a driven gear engaged with the driving gear and connected to the at least one plate.

10. The vacuum cleaner according to claim 1, wherein the at least one plate comprises a plurality of protrusions disposed on a surface thereof.

11. A vacuum cleaner, comprising:

a main body including a suction motor that generates a suction power;

a dust separator that communicates with the suction motor and that separates dust and dirt from air;

a dust collector body configured to store dust separated from the dust separator;

at least one plate configured to compress dust stored in the dust collector body and including a rotating shaft connected thereto; and

at least one gear configured to transfer a driving force to the at least one plate and including a gear axle coupled to the rotating shaft.

12. The vacuum cleaner according to claim 11, wherein the gear axle is inserted in the rotating shaft at an outer side of the dust collector body.

13. The vacuum cleaner according to claim 11, wherein a horizontal section of the gear axle is non-circular in shape.

14. The vacuum cleaner according to claim 13, wherein the horizontal section of the gear axle is polygonal.

15. The vacuum cleaner according to claim 13, wherein the horizontal section of an inner circumferential surface of the rotating shaft has a same shape as that of the gear axle.

16. The vacuum cleaner according to claim 11, wherein the collector body includes a fixed shaft to which the rotating shaft is coupled, the fixed shaft guiding rotation of the rotating shaft.

17. The vacuum cleaner according to claim 16, wherein the at least one plate further includes an interference prevention hole that prevents interference between the at least one plate and the fixed shaft.

18. A vacuum cleaner, comprising:

a main body having a suction motor that generates a suction power;

a dust separator that communicates with the suction motor and that separates dust and dirt from air;

a dust collector body configured to store dust separated from the dust separator;

at least one plate rotatably provided in the dust collector body and configured to compress dust stored in the dust collector body;

at least one gear configured to transfer a driving force to the at least one plate; and

a fastener coupled to the at least one plate and the at least one gear, the fastener being configured to guide transfer of the driving force to at least one plate.

19. The vacuum cleaner according to claim 18, wherein the at least one plate includes a rotating shaft and the at least one gear includes a gear axle coupled to the rotating shaft, and wherein the fastener is coupled to the rotating shaft and the gear axle in a state in which the gear axle is coupled to the rotating shaft.

20. The vacuum cleaner according to claim 19, wherein a horizontal section of the gear axle is non-circular in shape.

21. The vacuum cleaner according to claim 19, wherein the at least one gear is provided outside of the dust collector body and the gear axle is inserted in the dust collector body.
