Abstract: An air conditioner including an arc shaped discharge port formed in a cylindrical member of a housing; a main fan; an arc shaped heat exchanger between the main fan and an inner peripheral surface of the cylindrical member with respect to a radial direction of the cylindrical member; and an auxiliary fan. A discharge flow path is formed between an outer peripheral end of the heat exchanger and the inner peripheral surface of the cylindrical member. A guide flow path is formed outside the discharge flow path with respect to the radial direction of the cylindrical member. The auxiliary fan is in the discharge flow path and is configured to suck some of the air discharged through the discharge port into the guide flow path. The guide flow path returns the air sucked by the auxiliary fan to the auxiliary fan.

Abstract: A diffuser, which is used in an air conditioner, includes a central portion where a motor is disposed, and a plurality of blades radially disposed on an outer circumferential surface of the central portion and arranged at regular intervals along the outer circumferential surface of the central portion. An outer guide wall is disposed concentrically with the central portion and is formed to surround the plurality of blades. The outer guide wall includes a plurality of openings formed in a plurality of portions each of which corresponds to a space between two adjacent blades among the plurality of blades.
