Abstract

An air conditioner including an improved airflow regulator is configured to easily regulate the airflow. The air conditioner includes a fan assembly configured to blow air a diffuser assembly configured to include a center panel and a grill arranged at the outside of the center panel such that the air blown by the fan assembly flows through a flow passage formed between the center panel and the grill; and an airflow regulator configured to rotate the diffuser assembly so as to change a direction of the flow passage.

Claims

1. An air conditioner comprising:

a fan assembly to blow air; and

a diffuser assembly to direct movement of the air blown through the fan assembly, wherein the diffuser assembly comprises;

a center panel; and

a blade unit including a grill disposed at an outside of the center panel and a plurality of blades disposed between the center panel and the grill to direct movement of the air blown from the fan assembly,

wherein at least some parts of the blade unit are rotatably coupled to the center panel to change a direction of the air blown from the fan assembly according to a rotation of the at least some parts of the blade unit.

2. The air conditioner according to claim 1, wherein the blade unit comprises a first blade unit hinged to the center panel and a second blade unit fixed to the center panel.

3. The air conditioner according to claim 1, further comprising:

a cover coupled to a front of the center panel.

4. The air conditioner according to claim 3, wherein the cover comprises a guide plate in which a guide hole is formed.

5. The air conditioner according to claim 4, wherein the center panel comprises a guide protrusion inserted into the guide hole.

6. The air conditioner according to claim 4, wherein a rotation angle of the first blade is changed according to an elongated length of the guide hole.

7. The air conditioner according to claim 3, further comprising:

a support unit protruding forward of a first blade unit toward the cover.

8. The air conditioner according to claim 7, further comprising:

a pressing unit protruding from the cover toward the first blade unit.

9. The air conditioner according to claim 8, wherein:

if pressure is applied to the support unit by the pressing unit due to the guide plate sliding in a first direction, the first blade unit in which the support unit is formed rotates around a rotation shaft such that an airflow direction is directed in a second direction, different than the first direction.

10. The air conditioner according to claim 9, wherein:

the first blade unit is disposed at each of a left part and a right part of the center panel; and

if the guide plate slides to a left, the airflow caused by the first blade unit is directed to the left.
