Abstract

An air conditioner has a first foam insulation member disposed on a side of an outlet passage formation portion and a first drain pan opposite from cold air or a heat exchanger, adjacent to which the outlet passage formation portion and first drain pan are disposed. The first foam insulation member has a hardened layer made of a material identical to a material of a foam insulation member body at a portion contacting the outlet passage formation portion and a portion contacting the first drain pan. The present invention thereby provides an air conditioner capable of reducing squeaks at low cost with a simple configuration.

First claim

The invention claimed is:

1. An air conditioner comprising:
a resin member adjacent to at least one of cold air or a cold section; and
a foam insulation member opposing said at least one of the cold air or the cold section across the resin member,
wherein the foam insulation member has a hardened layer made of a material identical to a material of a foam insulation member body, the hardened layer being an integral part of the foam insulation member and being positioned at at least a portion of the foam insulation member contacting the resin member.

2. The air conditioner according to claim 1 , wherein
the resin member includes a passage formation member forming at least a part of an outlet passage downstream of a blowing fan through which the cold air flows, and
the foam insulation member is disposed on a side of the passage formation member opposite from the outlet passage.

3. The air conditioner according to claim 1 , wherein
the resin member includes a drain pan disposed on a lower side of a heat exchanger as the cold section, and
the foam insulation member is disposed on a lower side of the drain pan such that the hardened layer contacts a lower surface of the drain pan.

4. The air conditioner according to claim 1 , wherein
the hardened layer comprises a hardened layer formed on a front side of the foam insulation member facing the resin member and a hardened layer formed on a rear side of the foam insulation member opposite to the resin member.

5. The air conditioner according to claim 4 further comprising:
a holding member disposed on a side of the foam insulation member opposite from the resin member,
wherein the foam insulation member is fixed by being sandwiched between the resin member and the holding member.

6. The air conditioner according to claim 1 , wherein the hardened layer of the foam insulation member has a thickness of 1 μm or more and 2.0 mm or less.

7. The air conditioner according to claim 1 , wherein the foam insulation member is made of one material selected from polypropylene, polyethylene, and polystyrene, or a mixture of at least two materials selected from polypropylene, polyethylene, and polystyrene.
