Abstract

PURPOSE:To reduce the size and cost of the exterior unit, by dispensing with an air orienting plate and a babble and using an original propeller fan to blow air off in an oblique direction. CONSTITUTION:A heat exchanger 9 is mounted at the suction side of the propeller fan 2. An annular plate 5 is attached to the rear edges of blades of the propeller fan 2 concentrically with the rotary shaft of the fan. The outside diameter of the annular plate 5 is equal to 60 to 100% of that D of the fan. A protective guille 15 projects from the main body 7 of the exterior unit outside the annular plate 5. As a result, a centrifugal fan action is added and the pressure difference in the radial direction rather than in the axial direction is increased. Thereby, the blow-off in the oblique direction can be effected. Since the air c flows out without coming into touch with the annular plate 5, the pressure loss is prevented and the efficiency of blow-off of the air is raised.
