Abstract
A centrifugal blower for an air conditioner may include a centrifugal fan rotatably coupled to a motor, and a bell mouth guiding air into the centrifugal fan. The centrifugal fan may include a hub fixed to the motor, a main plate provided at an outer circumferential surface of the hub, a shroud surrounding the rotary shaft, the shroud positioned opposite the main plate to define a main gas flow path, and wings arranged along a circumferential direction of the suction opening between the main plate and the shroud. A rear axial end of the bell mouth may be inserted into the shroud through the suction opening so as to form a predetermined radial gap with the suction opening. A rear portion of the bell mouth may include alternately formed protrusions and recesses inserted into the shroud.
