Abstract

An air conditioner of present invention comprises a housing having an outer panel forming the exterior and an opening formed on the outer panel, a heat exchanger configured to exchange heat with air flowing into the housing, and a door unit configured to open or close the opening by moving forward or backward from the opening through which the heat exchanged air is discharged. Wherein the door unit comprises a door blade configured to open or close the opening, a door operating part configured to move the door blade forward or backward, and a controller configured to control the air discharged from the opening to be moved forward from the opening in a straight line or to be discharged radially from the opening by controlling a distance between the door blade and the opening.

First claim

What is claimed is:

1. An air conditioner comprising:
a housing having an opening;
a discharge guide disposed in the opening and having a guide opening;
a heat exchanger configured to exchange heat with air flowing into the housing; and
a door unit configured to open or close the guide opening by moving forward or backward from the guide opening through which the heat exchanged air is discharged,
wherein the door unit comprises:
a door blade configured to open or close the guide opening;
a first housing having at least one first guide diagonally formed between an outer side and an inner side of the first housing;
a second housing having a first coupling portion inserted into the at least one first guide and formed to move along the at least one first guide; and
a power transfer configured to transmit power for rotating the first housing using a gear.

2. The air conditioner of claim 1 , wherein the first housing is configured to be rotated relative to the second housing.

3. The air conditioner of claim 1 , wherein the door unit further comprises a housing cover having a second guide to guide the first coupling portion to move in a same direction as a direction of movement of the door blade.

4. The air conditioner of claim 3 , wherein the first coupling portion moves forward or backward along the at least one first guide and the second guide to move the door blade forward or backward when the power transfer rotates the first housing.

5. The air conditioner of claim 3 , wherein the housing cover is fixed to the housing.

6. The air conditioner of claim 3 , wherein the second housing is slidably movable relative to the housing cover.

7. The air conditioner of claim 1 , wherein the first housing comprises the gear formed in the inner side.

8. The air conditioner of claim 7 , wherein the gear is connected to the power transfer and is configured to rotate the first housing by a rotational force generated in the power transfer.

9. The air conditioner of claim 7 , wherein the gear is provided at a rear end portion of the first housing.

10. The air conditioner of claim 7 , wherein the gear part is connected to the power transfer.

11. The air conditioner of claim 7 , wherein the gear comprises a gear connected to the first housing.

12. The air conditioner of claim 1 , wherein the second housing is fixed to the door blade.

13. An air conditioner comprising:
a housing having an opening;
a discharge guide disposed in the opening and having a guide opening;
a heat exchanger configured to exchange heat with air flowing into the housing; and
a door unit configured to open or close the guide opening by moving forward or backward from the guide opening through which the heat exchanged air is discharged,
wherein the door unit comprises:
a door blade configured to open or close the guide opening;
a first housing having at least one first guide diagonally formed between an outer side and an inner side of the first housing;
a second housing having a first coupling portion inserted into the at least one first guide and formed to move along the at least one first guide, and fixed to the door blade;
a housing cover having a second guide to guide the first coupling portion to move in a same direction as a movement direction of the door blade, and on which the second housing is slidably mounted; and
a power transfer to transmit power for rotating the first housing using a gear.

14. The air conditioner of claim 13 , wherein the second housing is guided by the first housing and the housing cover and moves forward or backward while moving the door blade forward or backward when the power transfer rotates the first housing.

15. The air conditioner of claim 13 , wherein the first housing comprises the gear formed at the inner side and configured to receive a rotational force generated in the power transfer.
