PURPOSE:To construct a main body without increasing a height of the main body and a depth of it by a method wherein a plurality of stepwise rear edges of an evaporation tray are arranged so as to overlap with water receptacle trays, and receptacle tray surfaces of evaporation trays are inclined at an arbitrary angle toward a heat exchanger to cause some dripped water from the heat exchanger to be received at the evaporation trays. CONSTITUTION:A rising rib 14a having a predetermined height is provided at a downstream side of a heat exchanger 6 and on a projected plane of the heat exchanger. A receptacle tray surface 14b inclined at an arbitrary angle from a horizontal plane in a counterclockwise direction and extending toward the heat exchanger 6, and an evaporator tray 14 connecting the rising rib 14a with the receptacle tray surface 14b and composed of right and left side walls 14d forming the tray are made such that the rising rib 14a overlaps with the rear edge of the receptacle tray surface 14b and a plurality of stepwise trays are arranged so as to cause the rear edge 14c of the lower-most evaporator tray 14 to overlap the water receptacle tray 7. With such an arrangement, all the dripped water from the heat exchanger 6 can be received at the evaporator tray 14 and so the water may not drip into a room. Since the receptacle surface of the evaporator tray is inclined at an arbitrary angle toward the heat exchanger in a counter-clockwise direction, the main body can be constructed without increasing a height of the main body and its depth. |
