Abstract

Provided is a vacuum cleaner. The vacuum cleaner includes a cleaner body and a dust container separably mounted on the cleaner body. The dust container includes a dust collection body including a first chamber in which air and dust are separated from each other and a second chamber in which the dust separated in the first chamber are stored and a pressing member rotatably reciprocated between the first and second chambers within the dust collection body to compress the dust stored in the second chamber in one direction while moving from the first chamber to the second chamber.

First claim

What is claimed is:

1. A vacuum cleaner comprising:
a cleaner body; and
a dust container separably mounted on the cleaner body,
wherein the dust container includes
a dust collection body including a first chamber configured to separate dust from air flowing in the first chamber and a second chamber configured to store the dust separated in the first chamber; and
a pressing member provided to rotate in a reciprocating manner between the first and second chambers within the dust collection body and configured to move the dust from the first chamber to the second chamber,
wherein the dust collection body includes a partition wall that partitions the first chamber from the second chamber, and
a communication hole provided in the partition wall between the first and second chambers,
wherein the pressing member is configured to move between the first and second chambers through the communication hole.

2. The vacuum cleaner according to claim 1 , wherein the second chamber includes a first dust storage area, and
the first chamber includes a dust separation area and a second dust storage area disposed under the dust separation area,
wherein dust in the second dust storage area is moved to the first dust storage area.

3. The vacuum cleaner according to claim 2 , wherein the pressing member rotates about a prescribed axis to extend a prescribed distance into the second dust storage area and to rotate from the second dust storage area into the first dust storage area to push and compress the dust from the second dust storage area into the first dust storage area.

4. The vacuum cleaner according to claim 1 , wherein the pressing member includes a rotation shaft and a pressing plate which extends from the rotation shaft,
at least a portion of the rotation shaft being disposed in the communication hole.

5. The vacuum cleaner according to claim 4 , wherein a center of rotation of the rotation shaft is defined in the second chamber.

6. The vacuum cleaner according to claim 4 , wherein an axis of rotation of the rotation shaft is parallel to a cyclone flow axis in the first chamber.

7. The vacuum cleaner according to claim 1 , wherein the dust collection body includes
a main wall that defines the first chamber,
an auxiliary wall that defines the second chamber together with the main wall, and
a communication hole provided in the main wall to allow the first and second chambers to communicate with each other,
wherein the pressing member is configured to pass through the communication hole.

8. The vacuum cleaner according to claim 1 , further comprising a compression motor to drive the pressing member,
wherein the compression motor includes a bi-directionally rotatable motor, and when an external force is applied to the compression motor through the pressing member, the compression motor is configured to change a direction of rotation, and
wherein first and second contact surfaces for applying the external force to the pressing member are disposed in the first and second chambers, respectively.

9. The vacuum cleaner according to claim 8 , wherein an air guide to guide discharge of the air separated from the dust is disposed in the first chamber, and
wherein the first contact surface is a surface of the air guide.

10. The vacuum cleaner according to claim 8 , wherein the dust collection body includes a protrusion formed in the second chamber to accommodate at least one gear coupled between the compression motor and the pressing member, and
wherein the second contact surface is a surface of the protrusion in the second chamber.

11. The vacuum cleaner according to claim 8 , wherein the dust collection body includes a protrusion formed to accommodate at least one gear that transfers power from the compression motor to the pressing member, and
the pressing member has a prescribed shape corresponding to a shape of the protrusion to prevent interference between the protrusion and the pressing member.

12. The vacuum cleaner according to claim 8 , wherein the second contact surface is a portion of a wall that defines the dust collection body.

13. The vacuum cleaner according to claim 1 , wherein an opening through which the air separated from the dust is exhausted is defined in a lower region of the first chamber.

14. A vacuum cleaner comprising:
a cleaner body; and
a dust container separably mounted on the cleaner body,
wherein the dust container includes
a dust separation section,
a second dust storage section disposed under the dust separation section,
a first dust storage section for storing dust moved from the second dust storage section, the first dust storage section being partitioned from the dust separation section and the second dust storage section,
a pressing member configured to rotatably reciprocate between the first and second dust storage sections to move the dust stored in the second dust storage section into the first dust storage section and to compress the dust stored in the first dust storage section, and
a communication hole provided between the second dust storage section and the first dust storage section,
wherein the pressing member is configured to pass through the communication hole.

15. The vacuum cleaner according to claim 14 , wherein the pressing member includes a rotation shaft and a pressing plate that extends from the rotation shaft, and
at least a portion of the rotation shaft being disposed in the communication hole.

16. The vacuum cleaner according to claim 15 , wherein the pressing plate is disposed lower than an upper end of the communication hole.

17. The vacuum cleaner according to claim 14 , wherein an air guide is provided to exhaust the air separated from the dust in the dust separation section, the air guide disposed in the second dust storage section, and
when the pressing member rotates to contact the air guide, the pressing member is configured to change a direction of rotation.

18. The vacuum cleaner according to claim 14 , wherein, when the pressing member contacts a wall defining the first dust storage section, the pressing member is configured to change a direction of rotation.

19. A vacuum cleaner comprising:
a cleaner body; and
a dust container separably mounted on the cleaner body,
wherein the dust container includes
a dust collection body including a first chamber configured to separate dust from air flowing in the first chamber and a second chamber configured to store the dust separated in the first chamber; and
a pressing member provided to rotate in a reciprocating manner between the first and second chambers within the dust collection body and configured to move the dust from the first chamber to the second chamber, and
wherein the dust collection body includes
a main wall that defines the first chamber,
an auxiliary wall that defines the second chamber together with the main wall, and
a communication hole provided in the main wall to allow the first and second chambers to communicate with each other,
wherein the pressing member is configured to pass through the communication hole.
