Abstract

A vacuum cleaner is provided. The vacuum cleaner may include a main body, a dust collector, at least one pressing member, and a driver. The dust collector may be detachably attached to the main body and may include a dust storage chamber. The at least one pressing member may compress dust stored in the dust storage chamber. The driver may be disposed in the dust collector and actuate the at least one pressing member.

Claims

1. A vacuum cleaner, comprising:

a main body;

a dust collector detachably attached to the main body and including a dust storage chamber; and

at least one pressing member that compresses dust stored in the dust storage chamber, wherein the dust collector includes a driver that actuates the at least one pressing member.

2. The vacuum cleaner according to claim 1, wherein the driver is detachably coupled to the dust collector.

3. The vacuum cleaner according to claim 1, wherein the driver is disposed on the dust collector.

4. The vacuum cleaner according to claim 1, wherein the driver comprises a compression motor configured to rotate the at least one pressing member.

5. The vacuum cleaner according to claim 4, further comprising:

a power supply terminal provided on the main body that supplies power to the compression motor; and

a terminal part connected to the compression motor, wherein when the dust collector is attached to the main body, the terminal part is connected to the power supply terminal.

6. The vacuum cleaner according to claim 1, wherein the at least one pressing member comprises a first pressing member disposed in the dust storage chamber and which is bidirectionally rotatable.

7. The vacuum cleaner according to claim 6, wherein the at least one pressing member further comprises a fixed member disposed in the dust storage chamber, the fixed member interacting with the first pressing member to compress dust.

8. A vacuum cleaner, comprising:

a dust separation device;

a dust collector body, in which a dust storage chamber is disposed that stores dust separated by the dust separation device;

at least one pressing member that compresses dust stored in the dust storage chamber;

a driver coupled to the dust collector body that actuates the at least one pressing member; and

a main body, to which the dust collector body is detachably attached.

9. The vacuum cleaner according to claim 8, wherein the driver is connected to a rotational shaft of the at least one pressing member, and the driver or the rotational shaft is inserted through the dust collector body.

10. The vacuum cleaner according to claim 8, wherein the main body comprises a power supply terminal that supplies power to the driver, wherein the driver comprises:

a compression motor that rotates the at least one pressing member; and

a terminal part connected to the compression motor, the terminal part being selectively connected to the power supply terminal.

11. The vacuum cleaner according to claim 8, wherein the dust storage chamber comprises a compartment rib under a rotational shaft of the at least one pressing member.

12. The vacuum cleaner according to claim 8, wherein the at least one pressing member comprises a first pressing member that rotates and a fixed member that interacts with the first pressing member to compress dust, wherein the first pressing member is bidirectionally rotatable.

13. A vacuum cleaner, comprising:

a dust separation device;

a dust collector body, in which a dust storage chamber is disposed that stores dust separated by the dust separation device;

at least one pressing member that compresses dust stored in the dust storage chamber; and

a driver disposed in the dust separation device that actuates the at least one pressing member.

14. The vacuum cleaner according to claim 13, wherein the at least one pressing member is connected to the driver from under the dust separation device.

15. The vacuum cleaner according to claim 13, wherein the dust separation device comprises:

an accommodation part that accommodates the driver; and

a cover member that covers the accommodation part.

16. The vacuum cleaner according to claim 13, further comprising:

a power supply terminal on a main body that supplies power to the driver; and

a terminal part that transmits power to the driver when connected to the power supply terminal.

17. A vacuum cleaner, comprising:

a dust separation device;

a dust collector, in which a dust storage chamber is disposed that stores dust separated by the dust separation device;

at least one pressing member that compresses dust stored in the dust storage chamber; and

a driver disposed at an upper side of the dust storage chamber that actuates the at least one pressing member.

18. The vacuum cleaner according to claim 17, wherein the dust separation device is disposed in the dust collector.

19. The vacuum cleaner according to claim 18, further comprising a cover member configured to open and close both the dust separation device and the dust storage chamber, wherein the driver is disposed on the covet member.

20. The vacuum cleaner according to claim 19, further comprising a rotatable member disposed at a lower side of the cover member and rotatable by the driver, wherein the at least one pressing member extends downward from the rotatable member.

21. The vacuum cleaner according to claim 20, wherein the rotatable member comprises a coupling part configured to join the rotatable member to the cover member, and the coupling part or the driver is inserted through the cover member.

22. A vacuum cleaner, comprising:

a dust collector including a dust separation device and a dust storage chamber;

at least one pressing member in the dust storage chamber that compresses dust stored in the dust storage chamber;

a driver disposed in the dust collector that actuates the at least one pressing member; and

a terminal part connected to the driver, the terminal part transmitting power to the driver when connected to a power supply.
