Abstract

Disclosed is a cleaner. A cleaner according to an embodiment of the present invention comprises: a brush; and a removal member that is positioned adjacent to the brush. The brush is rotated to collect garbage, such as hair, located on a floor surface. The collected garbage, such as hair, may be pushed by the removal member and separated from the brush. The garbage, such as hair, separated from the brush may pass through a nozzle housing and may then be collected in a dust bin. Therefore, the garbage, such as hair, attached to the brush can be easily separated and collected without a separate removal process. Accordingly, user convenience can be improved.

First claim

The invention claimed is:

1 . A cleaner, comprising:
a frame; a roller rotatably coupled to the frame to extend in an extension direction, and including an adhesive material provided at an outer circumference thereof; a removal assembly extending in the extension direction of the roller, located at a section of the outer circumferential of the roller, and coupled to the frame so as to be rotatable with respect to the roller; at least one main gear coupled to the roller to rotate together with the roller; at least one sub-gear rotatably coupled to the frame, and gear-fitted to the main gear; and a link coupled to the at least one sub-gear and the removal assembly, respectively, wherein the removal assembly is rotated along the outer circumference of the roller.

2 . The cleaner of claim 1 , wherein the removal assembly comprises:
an extension wall extending along the extension direction of the roller and adjacent to the outer circumference of the roller at a radial outer side thereof; and a coupling frame located at an end of the extension wall, and rotatably coupled to the frame, wherein the extension wall of the removal assembly is rotated along the outer circumference of the roller.

3 . The cleaner of claim 2 , wherein the extension wall is located adjacent to the outer circumference of the roller.

4 . The cleaner of claim 2 , wherein the adhesive material has a predetermined roughness, and
a surface of the extension wall facing the outer circumference of the roller includes a material with a roughness matching that of the adhesive material.

5 . The cleaner of claim 1 ,
wherein the link and the removal assembly perform movement when the at least one sub-gear is rotated.

6 . The cleaner of claim 1 , wherein:
the at least one main gear comprises:
a first main gear located at a first end the roller; and
a second main gear located at a second end of the roller, and
the at least one sub-gear comprises:
a first sub-gear gear-fitted to the first main gear; and
a second sub-gear gear-fitted to the second main gear.

7 . The cleaner of claim 1 , wherein the link comprises:
a main link rotatably coupled to the removal assembly; and a sub-link rotatably coupled to the main link, and coupled to the sub-gear to rotate together therewith.

8 . The cleaner of claim 1 , wherein
the main gear includes more teeth than the sub-gear; and the main gear is rotated at a lower speed than the sub-gear.

9 . The cleaner of claim 1 , comprising:
a motor coupled to the roller to rotate the roller, wherein the motor provides force to one end of the roller.

10 . The cleaner of claim 1 , wherein the removal assembly is reciprocated by a predetermined distance along the outer circumference of the roller.

11 . The cleaner of claim 10 , wherein:
an object adhered to the adhesive material is moved in a first circumferential direction along the outer circumference of the roller by the rotation of the roller, and the removal assembly is rotated in a second circumferential direction different from the first circumferential direction in which the roller is rotated to press and to remove the object from the adhesive material.

12 . The cleaner of claim 11 , further comprising:
a dust bin detachably provided to communicate with the frame, wherein the removed object is introduced into the dust bin after being removed from the roller by the removal assembly.

13 . A cleaner, comprising:
a body; a nozzle housing detachably coupled to the body; and a nozzle assembly accommodated in the nozzle housing, and partially exposed to an outside of the nozzle housing, wherein the nozzle assembly comprises:
a frame coupled to the nozzle housing;
a roller rotatably coupled to the frame to extend in an axial direction, and including an adhesive material on an outer circumference thereof;
a removal assembly extending in the axial direction of the roller, and rotatably coupled to the frame with respect to the roller;
a main gear coupled to the roller to rotate together with the roller;
a sub-gear rotatably coupled to the frame, and gear-fitted to the main gear; and
a link coupled to the sub-gear and the removal assembly, respectively, and
wherein the removal assembly comprises:
an extension wall extending along the axial direction of the roller, a cross section of being defined in an arc shape to partially cover the outer circumference of the roller.

14 . The cleaner of claim 13 , wherein the extension wall of the removal assembly covers an area of less than half of an area of the outer circumference of the roller.

15 . The cleaner of claim 13 , wherein the extension wall has a rotation axis that is coaxial with a rotational axis of the roller, and a curvature of an inner surface of the extension wall matches a curvature of the outer circumference of the roller.

16 . The cleaner of claim 13 , wherein the extension wall of the removal assembly of the nozzle assembly is located adjacent to the outer circumference of the roller.

17 . The cleaner of claim 13 , wherein the removal assembly of the nozzle assembly further comprises a coupling frame that is continuous with an end of the extension wall in the axial direction of the roller and is rotatably coupled to the roller.

18 . The cleaner of claim 17 , wherein the nozzle assembly includes a pair of the coupling frames, and the pair of the coupling frames are respectively provided at each end of the extension wall in the axial direction of the roller.

19 . A robot cleaner, comprising:
a body; a nozzle housing detachably coupled to the body; and a nozzle assembly accommodated in the nozzle housing, and partially exposed to an outside of the nozzle housing, wherein the nozzle assembly comprises:
a frame coupled to the nozzle housing;
a roller rotatably coupled to the frame to extend in an axial direction, and including an adhesive material on an outer circumference thereof;
a removal assembly extending in the axial direction of the roller, located at a radial outer side of the roller, and coupled to the frame so as to be rotatable with respect to the roller;
a main gear coupled to the roller to rotate together with the roller;
a sub-gear rotatably coupled to the frame, and gear-fitted to the main gear; and
a link coupled to the sub-gear and the removal assembly, respectively, and
wherein the removal assembly is reciprocated by a predetermined distance in the outer circumferential direction of the roller when the roller is rotated.

20 . The robot cleaner of claim 19 , wherein the removal assembly is reciprocated along a portion of the outer circumference of the roller accommodated inside the nozzle housing.

21 . The robot cleaner of claim 19 ,
wherein the link is configured to rotate the removal assembly based on a rotation of the main gear and at a faster speed than the roller.

22 . The robot cleaner of claim 19 , wherein the roller is rotated in a clockwise or counterclockwise direction, and the removal assembly is reciprocated in a clockwise or counterclockwise direction by the predetermined distance along the outer circumferential of the roller.

23 . A cleaner, comprising:
