Abstract

Embodiments disclosed herein may provide an air conditioner having a case and a cover coupled to the case. A cover separation unit may separate the cover from the case at upper and lower sides. The cover separation unit may include a lever that slides along an outer surface of the case and a pusher rotatably coupled to the lever to rotate to push the cover. A guide may guide the pusher to rotate as the pusher is moved along an outer surface of the case.

First claim

What is claimed is:

1. An air conditioner, comprising:
a first case having a suction port;
a second case provided above the first case and having a discharge port;
a cover configured to be coupled to an outer surface of the first case to cover the suction port; and
a cover separation assembly configured to separate the cover from the first case,
wherein the cover separation assembly includes:
a lever configured to slide along an outer surface of the second case;
a first pusher coupled to the lever and configured such that, upon a sliding movement of the lever, the first pusher is moved to protrude away from the first case to push the cover away from the first case; and
a first guide provided at an outer surface of the first case and configured to guide a movement of the first pusher.

2. The air conditioner of claim 1 , wherein the cover separation assembly further includes:
a slider configured to slide along an outer surface of the first case;
a connection link connecting the slider and the lever;
a second pusher coupled to the slider and configured such that, upon a sliding movement of the slider, the second pusher is moved to protrude away from the first case to push the cover away from the first case; and
a second guide provided at an outer surface of the first case and configured to guide a movement of the second pusher.

3. The air conditioner of claim 2 , wherein the second pusher and the slider are provided below the first pusher.

4. The air conditioner of claim 2 , wherein the second pusher and the slider are positioned such that, when the cover is coupled to the first case, the second pusher and the slider are provided between the first case and the cover.

5. The air conditioner of claim 2 , wherein the second guide includes a groove to receive the slider and the second pusher.

6. The air conditioner of claim 2 , wherein the second guide includes a surface which has an inclination with respect to the outer surface of the first case to guide the movement of the second pusher.

7. The air conditioner of claim 1 , wherein at least a portion of the lever is exposed to an outside of the second case.

8. The air conditioner of claim 1 , wherein the lever is provided above the cover so as not to be covered by the cover.

9. The air conditioner of claim 1 , wherein the first pusher is positioned such that, when the cover is coupled to the first case, the first pusher is provided at an inner side of the cover.

10. The air conditioner of claim 1 , wherein the first pusher is positioned such that, when the cover is coupled to the first case, the first pusher is provided between the cover and the first case.

11. The air conditioner of claim 1 , wherein a lower surface of the first pusher has an inclination angle with respect to a vertical direction.

12. The air conditioner of claim 1 , wherein the first pusher is hinged to a lower end of the lever.

13. The air conditioner of claim 1 , wherein the first guide includes a surface which has an inclination with respect to the outer surface of the first case to guide the movement of the first pusher.

14. The air conditioner of claim 1 , wherein the first guide includes a groove configured to receive the first pusher.

15. The air conditioner of claim 1 , wherein the first guide has a groove formed in the outer surface of the first case to receive the first pusher, and a bottom of the groove has an inclined surface such that, when a downward force is applied to a top of the first pusher, a bottom of the first pusher slides along the inclined surface toward the cover to push the cover away from the first case.

16. The air conditioner of claim 1 , further comprising:
a fan provided inside of the first case and configured to suction air through the suction port and discharge air out of the discharge port;
a filter provided inside the first case to filter the air suctioned by the fan.

17. The air conditioner of claim 16 , wherein the filter is configured to fit through the suction port which is covered by the cover.

18. The air conditioner of claim 1 , wherein the cover separation assembly further comprises a return spring configured to provide a restoring force to the lever.

19. An air conditioner, comprising:
a case including a suction port through which air is suctioned and a discharge port through which the suctioned air is discharged;
a cover coupled to an outer surface of the case; and
a cover separation assembly configured to remove the cover from the case, wherein the cover separation assembly includes:
a lever configured to slide along the outer surface of the case;
a pusher rotatably coupled to the lever; and
a guide configured to receive the pusher and configured such that, upon a sliding movement of the lever, the pusher is rotated away from the outer surface of the case to push the cover away from the case.

20. The air conditioner of claim 19 , wherein the cover separation assembly further includes:
a slider connected to the lever and configured to slide along the outer surface of the case at a position below and spaced apart from the first pusher; and
a second pusher rotatably coupled to the slider and guided along the outer surface of the case to push the cover.
