PURPOSE:To enable an easy assembling work and reduction in a number of components, and to reliably perform a drain disposal, by molding is one body a drain pan and a bell mouth from plastic resin. CONSTITUTION:A drain pan 12 and a bell mouth 13 are molded from plastic resin, and a hinge 14 is located at their connecting part. An insulation layer 15 is monothically adhered to an outer circumference of the drain pan 12, and a drain nipple 16 pierces the insulation layer 15 to protrude downward. A suction port 17 being positioned opposite to and facing a centrifugal fan 6 is provided in the bell mouth 13, and heat exchanger supports 18a, 18b and 18c protruding forward are located at a top edge and two side edges of the bell mouth 13. Even if drain dew-condensated at the front of the bell mouth 13 drops down is the case of a cooling operation, it is reserved in the drain pan 12 united in one body with the bell mouth, and thus, drain disposal can be performed reliably. |
