When the room temp. rises up to a predetermined valve or more, this temp. rise is detected by a room temp. detecting part, and transmits a detection signal to control means to normally rotate a geared motor. Then, switching from a front discharge port to an upper discharge port is carried out. Upon this occasion, the convection of indoor air is promoted, and warm air staying at the upper part is agitated to particularly promote unification of indoor temp. distribution. In addition, the orientation direction of a warm air flow passage with respect to the upper discharge part is made rectilinear, a small flow pat resistance may be enough. Even when a large air amount is discharged through the upper discharge port, smooth blasting becomes possible and generation of noise can be effectively suppresses.
