Abstract

An air conditioner includes a housing including an inlet and an outlet, a heat exchanger arranged inside the housing to exchange heat with air sucked through the inlet, a fan configured to move air, which is heat-exchanged with the heat exchanger, to be discharged through the outlet, a motor configured to generate a rotational force, and a blade unit configured to guide air discharged to the outlet.

First claim

What is claimed is:

1. An air conditioner comprising:
a housing comprising an inlet and an outlet;
a heat exchanger arranged inside the housing to exchange heat with air suctioned through the inlet;
a fan configured to move the air, which is heat-exchanged with the heat exchanger, to be discharged through the outlet;
a motor configured to generate a rotational force; and
a blade assembly configured to guide the air to the outlet and receive the rotational force from the motor, the blade assembly comprising;
a main-blade configured to rotate in a first direction with respect to a first rotation center of the main-blade and adjust a discharge direction of the air discharged through the outlet based on the rotational force received from the motor,

a sub-blade rotatably coupled to the main-blade and configured to rotate in a second direction opposite to the first direction, based on the rotation of the main-blade in the first direction, to adjust a discharge speed of the air discharged through the outlet, the sub-blade including a first joint rotatably coupled to the main-blade and a second joint spaced apart from the first joint, and
a link provided to guide movement of the sub-blade by rotating with respect to a second rotation center so that the sub-blade rotates in the second direction, the link including a first end rotatably coupled to the second joint of the sub-blade and a second end provided to form the second rotation center.

2. The air conditioner of claim 1 , wherein
an outlet flow path is provided between the fan and the outlet, housing comprises;
a first guide member arranged adjacent to the inlet, and
a second guide member arranged to be outwardly spaced apart from the first guide member so as to form at least a portion of the outlet flow path, and the outlet flow path comprises;
a first outlet flow path formed between the blade assembly and the first guide member; and
a second outlet flow path formed between the blade assembly and the second guide member.

3. The air conditioner of claim 2 , wherein
in response to the rotation of the main-blade in the first direction, an area of the first outlet flow path is reduced and an area of the second outlet flow path is increased.

4. The air conditioner of claim 2 , wherein
in a heating operation, the main-blade rotates in the first direction to guide the air, which is discharged through the outlet, toward a lower side, and the sub-blade rotates in the second direction to block the first outlet flow path.

5. The air conditioner of claim 3 , wherein
the second joint is positioned above the first joint.

6. The air conditioner of claim 1 , wherein
the sub-blade is rotatably coupled to an end close to the inlet of the main-blade to form an angle with the main-blade,
wherein in a heating operation, an angle between the main-blade and the sub-blade is 120° to 180°.

7. The air conditioner of claim 2 , wherein
the link rotates in a same direction as the main-blade in response to the second rotation center of the link being located in front of the first rotation center of the main-blade.

8. The air conditioner of claim 2 , wherein
the link rotates in a direction opposite to the main-blade in response to the second rotation center of the link being located behind the first rotation center of the main-blade.

9. The air conditioner of claim 2 , wherein
the link comprises a curved shape.

10. The air conditioner of claim 1 , wherein
the main-blade further comprises a main-blade body; and a plurality of outlet holes penetrating the main-blade body,
wherein the air is discharged through plurality of outlet holes in response to closing the outlet by the main-blade.

11. The air conditioner of claim 1 , wherein
the motor comprises a stepper motor.
