Abstract

A filter cleaning device has an improved structure which is capable of effectively cleaning dust in a filter used in an air conditioner. The filter cleaning device includes: a filter; a brush unit movably installed at one side of the filter to separate dust from the filter; a brush movement unit configured so that the brush unit is movable along the filter; and brush guides installed at two sides of the brush unit to guide a movement of the brush unit. Each of the brush guides includes: a first guide groove formed so that the brush unit is moved to be in contact with the filter; and a second guide groove formed so that the brush unit is moved to be separated from the filter.

First claim

What is claimed is:

1. A filter cleaning device comprising:
a filter;
a brush unit movably installed at one side of the filter to separate dust from the filter;
a brush movement unit configured so that the brush unit is movable along the filter; and
brush guides installed at two sides of the brush unit to guide a movement of the brush unit,
wherein each of the brush guides comprises:
a first guide groove formed so that the brush unit is moved to be in contact with the filter; and
a second guide groove formed so that the brush unit is moved to be separated from the filter.

2. The filter cleaning device according to claim 1 , wherein each of the brush guides further comprises a first movement portion formed so that the brush movement unit is movable between the first guide groove and the second guide groove, and
in the first movement portion, the first guide groove is provided as a stepped shape higher than the second guide groove.

3. The filter cleaning device according to claim 2 , wherein each of the brush guides further comprises a second movement portion that is formed at an opposite side to the first movement portion and formed so that the brush movement unit is movable between the first guide groove and the second guide groove, and
in the second movement portion, the first guide groove is provided as a stepped shape lower than the second guide groove.

4. The filter cleaning device according to claim 1 , wherein the brush unit comprises:
a brush body;
a brush installed in the brush body facing the filter;
slide members installed at two sides of the brush body and provided to be movable at insides of the first guide groove and the second guide groove; and
a first elastic member installed between each slide member and the brush body.

5. The filter cleaning device according to claim 4 , wherein the brush unit further comprises:
a coupling housing comprising a first region coupled to the brush body and a second region movably coupled to the brush movement unit;
a distance adjustment member disposed in contact with one side of the brush body so as to move the brush body in the first region; and
a second elastic member disposed between the brush body and the coupling housing at an opposite side of the distance adjustment member in the first region.

6. The filter cleaning device according to claim 5 , wherein the distance adjustment member comprises:
a first adjuster having a first thickness; and
a second adjuster having a second thickness that is thicker than the first thickness.

7. The filter cleaning device according to claim 5 , wherein the brush movement unit comprises:
a shaft provided to be rotatable and extending in a movement direction of the brush unit;
rack gears formed in parallel with the shaft;
worm gears coupled to be movable along the shaft when rotated in engagement with the rack gears according to a rotation direction of the shaft; and
a driving member configured to generate a rotational force which is transferred to the shaft,
wherein the worm gears are disposed in the second region and are movable together with the brush unit.

8. The filter cleaning device according to claim 4 , further comprising a dust separation member disposed below the filter so as to separate dust attached to the brush,
wherein the dust separation member comprises:
a rotating body disposed in parallel with the brush body;
a motor configured to transfer a rotational force to the rotating body; and
a dust separator formed at an outside of the rotating body so as to separate the dust attached to the brush when the dust separator is rotated together with the rotating body.

9. The filter cleaning device according to claim 8 , wherein the dust separator is provided in a spiral shape.

10. The filter cleaning device according to claim 8 , further comprising a dust discharge unit configured to move the dust separated from the brush,
wherein the dust discharge unit comprises:
a suction case formed below the dust separator and the brush and having an opening into which the dust separated from the brush is introduced;
a suction motor configured to generate a suction force which is transferred to the suction case; and
a suction cover configured to open and close the opening.

11. The filter cleaning device according to claim 10 , wherein the dust discharge unit further comprises a cover adjuster coupled to be movable along the brush movement unit and having a first gear portion formed in a side opposite to the suction cover, and
the suction cover comprises a second gear portion formed to be opposite to the first gear portion so as to be engaged with the first gear portion.

12. The filter cleaning device according to claim 11 , wherein the cover adjuster is configured to be moved between a first position and a second position, and the cover adjuster is disposed on a movement path of the brush unit, is configured to be moved from the first position to the second position to be in contact with the brush unit, and is configured to move the suction cover so that the opening is opened.

13. The filter cleaning device according to claim 12 , wherein the dust discharge unit further comprises a restoring member installed at one side of the cover adjuster, and
the restoring member is configured to restore the cover adjuster from the second position to the first position.
