Abstract

An air conditioner including an orifice part provided at an outlet side of a fan, the orifice part having a main body with a ring shape and a noise blocking part which extends from the main body toward the fan and blocks a noise transmitted from the fan to a second heat exchange part, wherein the orifice part is configured to guide air discharged from the fan toward a discharge port.

First claim

What is claimed is:

1. An air conditioner comprising:
a case having a suction port and a discharge port;
a fan provided inside the case to generate a flow of air from the suction port toward the discharge port;
a heat exchanger comprising a first heat exchange part which is provided at an inlet side of the fan, and a second heat exchange part which is bent and extends from the first heat exchange part; and
an orifice part
provided at an outlet side of the fan to guide the air discharged from the fan toward the discharge port,
wherein the orifice part comprises:
a main body having a ring shape and extending from the discharge port to the fan,
a first flat surface part formed at one side of the main body that is adjacent to the heat exchanger, and
an extending part extended toward the fan from one portion of the flat surface part to block a noise from the fan.

2. The air conditioner of claim 1 , wherein the extending part is provided between a blade of the fan and the second heat exchange part.

3. The air conditioner of claim 2 , wherein the extending part is provided between a rotation route of the blade and a surface of the second heat exchange part.

4. The air conditioner according to claim 1 , wherein the case comprises a front panel, a rear panel, a right side panel, and a left side panel, whereby the lengths of the right and left side panels are smaller than the lengths of the front and rear panels.

5. The air conditioner of claim 4 , wherein the first heat exchange part extends in a direction corresponding to an extension direction of the rear panel, and the second heat exchange part extends in a direction corresponding to an extension direction of the side panel.

6. The air conditioner of claim 4 , wherein the discharge port is disposed at the front panel.

7. The air conditioner of claim 2 , comprising a partition wall to divide an internal space of the case into a heat exchange chamber in which the heat exchanger is provided and an electronic component chamber, wherein the orifice part is disposed between the second heat exchange part and the partition wall.

8. The air conditioner of claim 7 , wherein the orifice part further comprises:
a first fastening guide part which is provided at a first side of the main body and guides a fastening between the second heat exchange part and the main body; and
a second fastening guide part which is provided at a second side of the main body and guides a fastening between the partition wall and the main body.

9. The air conditioner of claim 8 , wherein the first fastening guide part comprises the first flat surface part having the same shape as a surface of the second heat exchange part.

10. The air conditioner of claim 8 , wherein the second fastening guide part comprises a second flat surface part having the same shape as a surface of the partition wall.

11. The air conditioner of claim 1 , wherein the orifice part further comprises an air guide part which extends from an inner circumferential surface of the main body in a direction that intersects with an extension direction of the extending part.

12. The air conditioner of claim 1 , wherein the extending part extends in a backward direction from a side of the main body by a distance that is greater than or equal to 5 mm and less than or equal to 15 mm.

13. The air conditioner of claim 1 , wherein the extending part extends downward from a first point of the main body and is connected to a second point of the main body.

14. The air conditioner of claim 1 , wherein the extending part that extends from the flat surface part toward the fan has a varying length.

15. The air conditioner of claim 14 , wherein the length of the extending part gradually increases and then gradually decreases from an upper side thereof toward a lower side thereof.

16. The air conditioner of claim 15 , wherein the length of the extending part is a circumferential length.

17. The air conditioner of claim 1 , wherein at least part of the fan extends inside the orifice part.

18. The air conditioner of claim 17 , wherein the leading edge and tip of a blade of the fan is disposed inside the orifice part.

19. The air conditioner of claim 18 , wherein an overlapping distance between the blade and the orifice is greater than or equal to 20 mm and less than or equal to 30 mm.

20. The air conditioner of claim 1 , wherein the orifice part further comprises a second flat surface part formed at other side of the main body to face the first surface part.
