Abstract

An air conditioner including a drain hose to be injection-molded is disclosed. An air conditioner includes a main body of an indoor unit, a heat exchanger disposed in the main body of the indoor unit, and a drain hose configured to discharge condensed water generated from the heat exchanger, wherein the drain hose is disposed in the main body and is injection-molded.

First claim

What is claimed is:

1. An air conditioner comprising:
a main body of an indoor unit;
a heat exchanger disposed in the main body of the indoor unit;
a drain pump configured to drain condensed water generated from the heat exchanger;
a first drain hose disposed inside the main body and connected to the drain pump to discharge condensed water; and
a second drain hose disposed at an outside of the main body and connected to the first drain hose to discharge condensed water to the outside of the main body,
wherein the first drain hose is injection-molded.

2. The air conditioner according to claim 1 , wherein the first drain hose includes:
a tube having a hollow; and
a connection portion formed at an end of the tube,
wherein the tube and the connection portion are injection-molded in one body.

3. The air conditioner according to claim 1 , wherein the first drain hose includes at least one of ethylene propylene diene monomer (EPDM) rubber and polypropylene (PP) plastic.

4. The air conditioner according to claim 2 , wherein the main body of the indoor unit includes a counterpart connected to the first drain hose,
wherein the counterpart includes at least one of a connection member mounted at a drain hole of the main body and a drain pump disposed in the main body.

5. The air conditioner according to claim 4 , wherein the connection portion includes:
a first connection portion coupled to the connection member; and
a second connection portion coupled to the drain pump,
wherein the first connection portion and the second connection portion are located perpendicular to each other.

6. The air conditioner according to claim 5 , wherein the first connection portion and the tube are injection-molded in one body.

7. The air conditioner according to claim 5 , wherein the second connection portion and the tube are injection-molded in one body.

8. The air conditioner according to claim 5 , wherein the connection portion is forcedly inserted into the counterpart.

9. The air conditioner according to claim 5 , wherein the connection portion includes:
a contact increasing portion protruding in a radial direction, located at an outer end of the connection portion.

10. The air conditioner according to claim 5 , wherein an inner surface of the connection portion is deformed to correspond to a shape of the counterpart.

11. The air conditioner according to claim 5 , wherein the connection portion has a thickness larger than a thickness of the tube.

12. The air conditioner according to claim 2 , wherein the tube includes:
a bending portion formed to be bent at a right angle.

13. The air conditioner according to claim 4 , wherein:
the first drain hose configured to interconnect the drain pump and the connection member at the inside of the main body of the indoor unit; and
the second drain hose connected to the connection member at the outside of the main body of the indoor unit, so as to discharge condensed water.

14. An air conditioner comprising:
a main body of an indoor unit;
a heat exchanger disposed in the main body of the indoor unit;
a drain tray configured to collect condensed water generated from the heat exchanger, and discharge the collected condensed water;
a drain pump disposed in the drain tray; and
a drain hose connected to the drain pump, configured to discharge the condensed water to an outside of the main body,
wherein the drain hose includes:
a tube having a hollow therein; and
a connection portion formed at an end of the tube, configured to be connected to the drain pump, and
wherein the tube and the connection portion are injection-molded in one body.

15. The air conditioner according to claim 14 , wherein the tube includes:
a bending portion formed to be bent at a right angle.

16. The air conditioner according to claim 14 , wherein the drain hose includes at least one of ethylene propylene diene monomer (EPDM) rubber and polypropylene (PP) plastic.

17. The air conditioner according to claim 14 , wherein the connection portion is forced inserted into the drain pump.

18. The air conditioner according to claim 14 , wherein an inner surface of the connection portion is deformed to correspond to a shape of the drain pump.

19. The air conditioner according to claim 14 , wherein the connection portion includes:
a contact increasing portion configured to increase a size of a region contacting the drain pump.

20. The air conditioner according to claim 14 , wherein the connection portion has a thickness larger than a thickness of the tube.
