Abstract

Provided are an air-conditioner and a controlling method thereof. The air-conditioner includes a blower fan forcibly generating a flow of air, a filter disposed on a flow path of the air that forcibly flows by the blower fan, and a vibration actuator disposed on a side of the filter. The method for controlling an air-conditioner includes disposing a collection part under a filter of an air-conditioner, vibrating a vibration actuator disposed on a side of the filter, and separating the collection part from a lower side of the filter.

Claims

1. An air-conditioner comprising:

a blower fan generating a flow of air;

a filter disposed on a flow path of the air that flows by the blower fan; and

a vibration actuator disposed on a side of the filter.

2. The air-conditioner according to claim 1, further comprising a collection part collecting dusts separated from the filter,

wherein the collection part is selectively overlap the filter in a vertical direction.

3. The air-conditioner according to claim 2, wherein the collection part is formed of a flexible material, and the air-conditioner further comprises a collection roller for selectively winding or spreading the collection part according to a rotation direction thereof.

4. The air-conditioner according to claim 3, wherein the collection roller rotates in one direction to allow the collection part to vertically overlap the filter, and

the collection roller rotates in the other direction to prevent the collection part from vertically overlapping the filter.

5. The air-conditioner according to claim 4, wherein the collection roller recovers the collection part so that a top surface of the collection part faces the outside.

6. The air-conditioner according to claim 3, further comprising a recovery box disposed under the collection roller, the recovery box having a dust receiving space for receiving the dusts separated from the collection part.

7. The air-conditioner according to claim 6, wherein the recovery box is detachably disposed on a front panel.

8. The air-conditioner according to claim 3, further comprising a brush disposed on a side of the collection roller to contact one surface of the collection part.

9. The air-conditioner according to claim 8, wherein a portion at which the brush contacts the collection part vertically overlaps the dust receiving space.

10. The air-conditioner according to claim 1, wherein the vibration actuator is an ultrasonic vibrator.

11. The air-conditioner according to claim 1, wherein the filter comprises an antistatic coating layer.

12. The air-conditioner according to claim 2, wherein each of the filter and the collection part is disposed in parallel with the ground, and

the collection part has a width equal to or greater than that of the filter.

13. The air-conditioner according to claim 2, further comprising:

a body comprising the blower fan, the filter, and the vibration actuator therein;

a front panel disposed on a bottom surface of the body; and

a suction hole defined in the front panel,

wherein the filter is disposed above the suction hole, and

the collection part is disposed between the filter and the suction hole.

14. The air-conditioner according to claim 13, further comprising a collection part guide fixed to the inside of the body to guide movement of the collection part.

15. A method for controlling an air-conditioner, the method comprising:

disposing a collection part under a filter of an air-conditioner;

vibrating a vibration actuator disposed on a side of the filter; and

separating the collection part from a lower side of the filter.

16. The method according to claim 15, further comprising separating dusts collected in the collection part to recover the separated dusts into a recovery box,

wherein the separating of the collection part from the lower side of the filter and the recovering of the separated dusts into the recovery box are simultaneously performed.

17. The method according to claim 15, further comprising recognizing a filter cleaning command,

wherein, when the filter cleaning command is recognized, the collection part is disposed under the filter of the air-conditioner.

18. The method according to claim 17, further comprises stopping an operation of a blower fan when the filter cleaning command is recognized.

19. The method according to claim 17, further comprising measuring a driving time of the air-conditioner,

wherein, when the measured driving time exceeds a set-up time, the filter cleaning command is recognized.

20. The method according to claim 17, wherein, when the filter cleaning command is input through an input unit by a user, the filter cleaning command is recognized.
