Abstract

A vacuum cleaner is provided. The vacuum cleaner may include a vacuum cleaner, comprising a main body, and a dust separator selectively on the main body, the dust separator comprising a dust separation device, a dust compression device having at least one compression member disposed therein, the at least one compression member being configured to be rotated to compress dust, and a storage device.

Claims

1. A vacuum cleaner, comprising:

a main body; and

a dust separator mounted on the main body, the dust separator comprising;

a dust separation device;

a dust compression device having a compression body forming a compression chamber, the compressor body being provided with at least one compression member configured to compress dust; and

a storage device having a storage chamber that stores compressed dust, wherein the storage device is disposed below the dust compression device, wherein the dust compression body comprises a first wall having at least one dust introduction portion and a second wall disposed opposite the first wall having at least one discharge hole through which compressed dust compressed by the at least one compression member is discharged, wherein the storage device comprises a dust inlet to which the compressed dust is introduced, and wherein the second wall is disposed between the compression chamber and the storage chamber.

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 that compresses dust by interaction with the first compression member.

3. The vacuum cleaner of claim 2, wherein the first compression member comprises:

a rotatable shaft that extends substantially perpendicular to the second wall; and

a compression plate attached to the rotatable shaft.

4. The vacuum cleaner of claim 3, wherein the second compression member comprises:

a fixed shaft; and

a compression plate attached to fixed shaft.

5. The vacuum cleaner of claim 3, further comprising a drive device that rotates the first compression member.

6. The vacuum cleaner of claim 5, wherein the drive device is provided below a lower wall of the compression body.

7. The vacuum cleaner of claim 5, wherein the drive device comprises:

an operation device that generates a driving force; and

a transmission portion connected to the rotatable shaft that transmits the driving force of the operation device to the rotatable shaft.

8. The vacuum cleaner of claim 7, wherein the operation device comprises:

an operation portion configured to be operated by a user; and

a connection portion connected with the transmission portion.

9. The vacuum cleaner of claim 8, wherein the connection portion and the transmission portion comprise gears.

10. The vacuum cleaner of claim 9, wherein a diameter of the connection portion is larger than a diameter of the transmission portion so that when the connection portion rotates a first angle, the transmission portion rotates a second angle larger than the first angle.

11. The vacuum cleaner of claim 1, wherein the dust compression device further comprises an opening and closing device configured to allow or block communication between the dust compression device and the dust storage device.

12. The vacuum cleaner of claim 11, wherein the opening and closing device comprises:

an opening and closing member; and

an operation member configured to operate the opening and closing member to allow or block communication between the dust compression device and the dust storage device.

13. The vacuum cleaner of claim 12, wherein the operation member is configured to rotate the opening and closing member to a first position, at which at least one opening in the opening and closing member aligns with the at least one discharge hole in the compression body to allow communication between the dust compression device and the dust storage device, or to a second position, at which the opening and closing member blocks the at least one discharge hole in the compression body to block communication between the dust compression device and the dust storage device.

14. The vacuum cleaner of claim 1, wherein the at least one dust introduction portion and the dust inlet are disposed in substantially parallel planes.

15. The vacuum cleaner of claim 1, wherein the at least dust introduction portion and the at least one discharge hole are disposed on opposite walls of the compression body.

16. The vacuum cleaner of claim 1, wherein the first wall is an upper wall of the compression body and the second wall is a lower wall of the compression body.

17. The vacuum cleaner of claim 1, wherein the storage device corresponds in shape to the dust compression device.
