Abstract

Air conditioner of a new structure which can reduce a total size of the air conditioner, and reduce noise in operation, while providing a high air flow rate and a high air pressure. The air conditioner includes a cabinet having a plurality of air passages (100a, 100b) for drawing and discharging air, a heat exchanger (11) in the cabinet, a helical fan (13) having a cylindrical hub (132), and a plurality of blades (133) each formed on an outside circumferentical surface of the hub (132) twisted along an axis direction of the hub (132) in a helix starting from one end to the other end of the hub (132), for forced blow of air in an axial direction which is a vertical direction of the cabinet, a driving motor (12) under the helical fan (13) for rotating the helical fan (13) in one direction, a motor mount (18) mounted in the cabinet for supporting the driving motor (12), and an air guide (19) over the helical fan (13) for guiding air from the helical fan (13) to flow to an outer side.
