By the operation of the blower (15), the outside air is sucked from the opening at the upper end of one area (16a) of the duct (16) and introduced into the machine room (11) as shown by the arrow (3), and the inside It circulates to cool units such as the condenser (13) and the compressor (14), rises in the other duct area (16b), and flows out through its upper end opening as indicated by arrow (4).
Therefore, since this cooling air is introduced through the duct on the back surface of the case main body, it is not necessary to inhale through the hole in the cover on the front surface of the machine room as in the conventional case, and therefore the cover (20) having no vent hole is provided. be able to. Further, since the air is taken in at a higher position than in the conventional case, the air having a relatively small amount of dust is absorbed and used for cooling.
