Abstract

PROBLEM TO BE SOLVED: To miniaturize a main body without spoiling the heat insulating performance of a box type heat insulating member by a method, wherein the heat insulating member, opposed to the upper part of a heat exchanger, is provided with a notch, while a wiring, being led out of a drain pump, is penetrated through the notch to introduce the same into an electrical instrument unit. SOLUTION: A box type heat insulating member 2, opposed to the upper part of a heat exchanger 6 and arranged at the inside of the ceiling plate 1a of a case main body 1, is provided with a notch 2a. In this case, a wiring 9a, led out of a drain pump 9, is penetrated through the notch 2a to introduce the same into an electric instrument unit 8. According to this method, for example a constitution, which eliminates generation of dew condensation on the case main body 1 due to leakage of cold air through the mating part between the lower end of the box type heat insulating member 2 and the upper end of a drain pan 7 upon cooling operation is obtained. Furthermore, the wiring 9a is led so as not to be laid along the bottom of the drain pan 7 whereby a space, provided between the drain pan 7 and a decorative panel 12 becomes unnecessary.
