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 suction nozzle in communication with the main body, that sucks air into the main body;

a dust separator removably coupled to the main body, the dust separator separating dust from the air sucked into the main body by the suction nozzle and comprising;

a dust separator device that separates dust from air sucked into the dust separator;

a dust container configured to store the separated dust, wherein the dust container comprises;

a dust container body;

at least one compression member to compress the dust within the dust container;

a lower cover attached to the dust container body;

a driving device configured to automatically rotate the at least one compression member and having a drive source located on the main body; and

a power transmission device configured to transmit power from the drive source to the at least one compression member, wherein the power transmission device comprises a main body transfer part and a transfer device selectively connected to the main body transfer part, the transfer device having a first transfer part provided at a lower side of the lower cover and a second transfer part provided at an upper side of the first transfer part and connected to the first transfer part, wherein the second transfer part transmits power from the drive source to the at least one compression member, and wherein, when the lower cover opens an inner space of the dust container body by rotation, the first and second transfer parts remain connected to the lower cover for movement with the lower cover.

2. The vacuum cleaner of claim 1, wherein the at least one compression member comprises a rotatable first compression member and a fixed second compression member.

3. The vacuum cleaner of claim 2, wherein the second compression member is attached to a fixed shaft, and wherein the fixed shaft is integrated with a top surface of the dust container.

4. The vacuum cleaner of claim 3, wherein the fixed shaft includes a coupling boss that extends downward therefrom configured to be inserted into a rotatable shaft of the first compression member, and wherein an insertion member couples the rotatable shaft to the coupling boss.

5. The vacuum cleaner of claim 4, wherein the drive source comprises a compression motor.

6. The vacuum cleaner of claim 2, wherein the power transmission device further comprises:

a fixed part disposed on the second transfer part and coupled to the first transfer part;

a connection part configured to be coupled to the rotation shaft and selectively coupled to the fixed part; and

an elastic member disposed on the first transfer part to elastically support the second transfer part.

7. The vacuum cleaner of claim 6, wherein the first transfer part comprises a gear.

8. The vacuum cleaner of claim 7, wherein the first transfer part comprises:

a gear body;

a plurality of gear teeth disposed along a circumferential surface of the gear body;

a magnetic member disposed on the gear body; and

a gear cover.

9. The vacuum cleaner of claim 8, further comprising a detector disposed on a mounting part of the main body, the mounting part being configured to receive the dust separator seated thereon, the detector being configured to detect a rotational position of the first compression member by detecting a magnetic force of the magnetic member.

10. The vacuum cleaner of claim 8, wherein a portion of the gear body passes through an opening in the lower cover, and wherein a rotation guide guides rotation of the portion.

11. The vacuum cleaner of claim 6, wherein the second transfer part comprises a hole at a central portion thereof and a plurality of guide protrusions.

12. The vacuum cleaner of claim 11, wherein the fixed part comprises an insertion protrusion at a central portion thereof and a plurality of positioning through holes.

13. The vacuum cleaner of claim 12, wherein the connection part comprises an insertion protrusion receiving part at a central portion thereof and a plurality of guide protrusion receiving parts.

14. The vacuum cleaner of claim 1, wherein the vacuum cleaner is an upright type vacuum cleaner.
