Abstract

An indoor unit for an air conditioner, which can efficiently distribute air discharged from a turbo fan and reduce noises, comprising a turbo fan (2) which is disposed in a casing (1) and discharges air, sucked from a front side thereof, radially outwardly relative to an axis thereof, and air flow control members (11) mounted to outlets (21-24) provided on the casing (1) and each having a planar vane (12) and a plurality of curved vanes (13-15) arranged lengthwise of the planar vane (12), wherein the plurality of curved vanes (13-15) have curvatures gradually increasing from a back side toward a front side in a direction of rotation of the turbo fan (2) and spacings between adjacent curved vanes become smaller from the back side toward the front side in the direction of rotation of the turbo fan (2).
