Abstract

A cleaner is provided. The cleaner includes a transfer device, and a dust collecting apparatus connectable to the transfer device and configured to filter out rubbish transferred from the transfer device. The dust collecting apparatus includes a housing in which a first dust chamber is formed, and including a guide recessed inwardly from an outer surface, a handle configured to be movable on the outside of the housing and provided to cover at least a portion of the guide, a first rubbish removal member configured to be movable inside the housing based on the movement of the handle, and configured to discharge rubbish collected in the first dust chamber, and a link configured to connect the handle to the first rubbish removal member, and having a movement guided by the guide.

First claim

What is claimed is:

1. A cleaner comprising:
a suction head;
a dust collector having one end mounted on the suction head, and configured to form a dust chamber to collect rubbish introduced through the suction head; and
an extension member slidably coupled to the dust collector,
wherein the extension member comprises:
a rubbish remover configured to be slidable along an extension direction of the extension member in the dust chamber and configured to discharge the rubbish of the dust chamber to an outside of the dust collector,
an opening and closing frame disposed on an end of the extension member facing the suction head, the opening and closing frame configured to interlock with the rubbish remover and to be slidable along the extension direction of the extension member in order to open and close the dust chamber,

wherein the opening and closing frame comprises a chamber inlet formed to allow air introduced from the suction head to flow into the dust chamber.

2. The cleaner of claim 1 , wherein the opening and closing frame further comprises:
an opening and closing member in which the chamber inlet is formed; and an opening and closing cover configured to open and close the chamber inlet by a suction force formed in the dust chamber.

3. The cleaner of claim 2 , wherein one portion of the opening and closing cover is fixed to the opening and closing member, and another portion different from the one portion is deformable by the suction force formed in the dust chamber.

4. The cleaner of claim 2 , wherein the opening and closing frame further comprises a portion configured to seal between the dust collector and the opening and closing member and arranged along an edge of the opening and closing member.

5. The cleaner of claim 4 ,
wherein the portion of the opening and closing frame is formed to include a more flexible material than the opening and closing member.

6. The cleaner of claim 1 , wherein the extension member further comprises:
a connector configured to connect the rubbish remover to the opening and closing frame, and
a discharge opening formed between the rubbish remover and the opening and closing frame and configured to discharge the rubbish of the dust chamber.

7. The cleaner of claim 1 ,
wherein the opening and closing frame moves away from the dust collector to open the dust chamber when the rubbish remover slides to be moved out of the dust chamber, and
wherein the opening and closing frame moves closer to the dust collector to close the dust chamber when the rubbish remover slides to be inserted into the dust chamber.

8. The cleaner of claim 1 , wherein the extension member further comprises
a handle arranged at an opposite end to the end of the extension member in which the opening and closing frame is arranged; and
a fan motor unit configured to generate a suction force for the dust chamber and arranged between the opening and closing frame and the handle.

9. The cleaner of claim 8 , further comprising:
a battery arranged between the handle and the fan motor unit of the extension member.

10. The cleaner of claim 8 , wherein the dust collector further comprises a discharge port formed at a portion of a rear surface thereof corresponding to a position of the fan motor unit in a state in which the opening and closing frame closes the dust chamber.

11. The cleaner of claim 8 , further comprising:
a motor filter configured to filter air introduced to the fan motor unit,
wherein the motor filter is arranged between the fan motor unit and the dust chamber.

12. The cleaner of claim 1 , further comprising:
a filter arranged in the dust chamber of the dust collector and configured to filter out the rubbish introduced through the suction head, and
wherein when the extension member slides with respect to the dust collector, the rubbish remover is slidable along one surface of the filter on which the filtered out rubbish is placed.

13. The cleaner of claim 1 ,
wherein the dust chamber is a first dust chamber,
wherein the extension member further comprises a cyclone configured to remove the rubbish from air passing through the first dust chamber, and
wherein the dust collector comprises a second dust chamber in which the rubbish separated by the cyclone is collected.

14. The cleaner of claim 13 ,
wherein the rubbish remover is a first rubbish remover, and
wherein the extension member further comprises a second rubbish remover configured to be slidable along the second dust chamber and the first dust chamber to discharge the rubbish of the second dust chamber based on a sliding movement of the extension member with respect to the dust collector.
