An evaporator mounting area 32a is arranged on the upper surface of the first lower volute plate 32, close to the end edge of the first lower volute plate 32, for mounting the evaporator. A water baffle is arranged on the edge of the evaporator mounting area 32a to prevent the condensate water generated by the evaporator from flowing out. In this embodiment, the edge of the first lower volute plate 32 is bent upward by 90 degrees to form a reinforcing portion.
