Abstract

A component unit of an air conditioner includes a casing having a metallic top panel, a heat exchanger disposed in the casing and including a heat transfer tube made of a material that has higher ionization tendency than the metallic top panel, a heat insulating member, having an opening, that covers an inner surface of the metallic top panel, a supporter, having a fixing part fixed to the inner surface inside the opening, that supports the heat exchanger, and a preventing member that prevents condensation water from traveling to the supporter from a region of the inner surface between an edge of the opening and the fixing part.

First claim

What is claimed is:

1 . A component unit of an air conditioner, comprising:
a casing having a metallic top panel; a heat exchanger disposed in the casing and including a heat transfer tube made of a material having higher ionization tendency than the metallic top panel; a heat insulating member, having an opening, that covers an inner surface of the metallic top panel; a supporter, having a fixing part fixed to the inner surface inside the opening, that supports the heat exchanger; and a preventing member that prevents condensation water from traveling to the supporter from a region of the inner surface between an edge of the opening and the fixing part.

2 . The component unit of claim 1 , wherein the preventing member prevents the condensation water generated in the region from traveling to the supporter.

3 . The component unit of claim 2 , wherein the preventing member includes a projection extending in a downward direction of the unit from the region.

4 . The component unit of claim 3 , wherein the preventing member further includes a base, disposed between the projection and the fixing part, having a shorter length than the projection in the downward direction.

5 . The component unit of claim 3 , wherein the projection extends to the fixing part.

6 . The component unit of claim 1 , wherein the preventing member eliminates or reduces generation of the condensation water in the region.

7 . The component unit of claim 6 , wherein the preventing member includes an auxiliary heat insulating member, separate from the heat insulating member, that covers the region.

8 . The component unit of claim 1 , wherein the preventing member includes an intermediate portion between the metallic top panel and the fixing part.

9 . The component unit of claim 8 , further comprising:
a fastening member that fastens the fixing part to the metallic top panel together with the intermediate portion.

10 . The component unit of claim 9 , wherein the intermediate portion has higher hardness than the heat insulating member.

11 . The component unit of claim 9 , wherein
the fixing part has a fastening hole through which the fastening member passes, and the component unit further comprises a resin fixing piece that:
is disposed under the fixing part,
is fixed to the fastening member, and
closes a clearance between an edge of the fastening hole and the fastening member.

12 . The component unit of claim 8 , wherein
the intermediate portion has a cutout, and the fixing part is configured to contact the metallic top panel through the cutout.

13 . The component unit of claim 1 , wherein the preventing member is made of a resin material.

14 . An air conditioner comprising:
the component unit according to claim 1 .
