Abstract

An air conditioner (AC) indoor unit includes a housing having an inlet and an outlet; a heat exchanger arranged inside the housing; a blower fan for sucking in air at the inlet to be subject to heat exchange with the heat exchanger, and discharging the heat-exchanged air out of the outlet; and an air flow control device for controlling an air flow discharged from the outlet by sucking in air around the outlet. The AC indoor unit may control the direction of a discharged air flow without a conventional blade structure, thereby increasing an amount of discharged air, reducing circulation noise, and enabling design differentiation.

First claim

What is claimed is:

1. An air conditioner comprising:
a housing having an inlet and an outlet;
a heat exchanger arranged inside the housing;
a fan arranged to draw air into the housing through the inlet to heat exchange with the heat exchanger and discharge the heat-exchanged air from the housing through the outlet; and
a drain tray arranged to collect water condensed at the heat exchanger,
wherein the drain tray comprises a discharging guide rib arranged to guide the air discharged through the outlet.

2. The air conditioner of claim 1 ,
wherein the discharging guide rib extends in a circumferential direction relative to a center of the air conditioner.

3. The air conditioner of claim 1 ,
wherein the discharging guide rib extends in a radial direction relative to a center of the air conditioner.

4. The air conditioner of claim 3 ,
wherein the drain tray comprises a plurality of discharging guide ribs, and
the plurality of discharging guide ribs are arranged along a circumferential direction relative to the center of the air conditioner and are arranged to be separate from one another.

5. The air conditioner of claim 4 ,
wherein the plurality of discharging guide ribs are arranged to be parallel to one another.

6. The air conditioner of claim 4 ,
wherein a gap between a pair of neighboring discharging guide ribs of the plurality of discharging guide ribs increases in a flow direction of the discharged air.

7. The air conditioner of claim 4 ,
wherein a gap between a pair of neighboring discharging guide ribs of the plurality of discharging guide ribs decreases in a flow direction of the discharged air.

8. The air conditioner of claim 3 ,
wherein the housing comprises a discharging guide rib extending in a radial direction relative to the center of the air conditioner to correspond to the discharging guide rib of the drain tray.

9. The air conditioner of claim 8 ,
wherein the discharging guide rib of the drain tray and the discharging guide rib of the housing are arranged to abut each other.

10. The air conditioner of claim 9 ,
wherein the discharging guide rib of the drain tray and the discharging guide rib of the housing are arranged to be coplanar.

11. The air conditioner of claim 8 ,
wherein the discharging guide rib of the housing is arranged to extend across the outlet of the housing.

12. The air conditioner of claim 1 ,
wherein the drain tray comprises an outlet arranged to correspond to the outlet of the housing,
wherein the discharging guide rib of the drain tray is arranged to extend across the outlet of the drain tray.

13. The air conditioner of claim 1 ,
wherein the housing comprises a top housing and a bottom housing,
wherein the bottom housing comprises an inner housing having an outer guide surface and an outer housing having an inner guide surface, and an outlet path for the outlet is formed between the outer guide surface and the inner guide surface.

14. The air conditioner of claim 13 ,
wherein the drain tray is arranged between the top housing and the bottom housing.

15. The air conditioner of claim 13 ,
wherein the outlet is arranged to correspond to an outlet of the drain tray.

16. The air conditioner of claim 13 ,
wherein the housing further comprises a middle housing arranged between the top housing and the bottom housing,
wherein the drain tray is arranged between the top housing and the middle housing.

17. The air conditioner of claim 1 ,
wherein the discharging guide rib extends from the drain tray.

18. An air conditioner comprising:
a housing having an inlet and an outlet;
a heat exchanger arranged inside the housing;
a fan arranged to draw air into the housing through the inlet to heat exchange with the heat exchanger and discharge the heat-exchanged air from the housing through the outlet; and
a drain tray arranged to collect water condensed at the heat exchanger, and including an outlet arranged to correspond to the outlet of the housing and a discharging guide rib arranged to extend across the outlet of the drain tray to guide the air discharged through the outlet of the housing.
