PURPOSE: To prevent generation of creaks due to the variation of temperature, by putting some interposing materials between a foamed polystyrene molding and other constituents, in an electric appliance using foamed polystyrene moldings as a part of the constituents in an indoor unit of a heat pump type air conditioner. CONSTITUTION: An indoor unit is constituted of an external board 1, a fan motor 2, a fan 3, a heatexchanger 4, and a drain pan 5 receiving the condensate from the heatexchanger 4. The drain pan 5 is made of a light and easily moldable foamed polystyrene and it is fitted in the external board 1. A metallic stay 14 is attached to fix the drain pan. Accordingly, immediately after the indoor unit has started the heating operation or when it has stopped heat operation, the drain pan 5 expands or contracts and the external board 1 and the stay 14 getting in contact therewith rub against it and hence, creaks are easily brought. Therefore, a buffer material 11 is interposed between the drain pan and the external board to prevent the creaks. |
