Abstract: Provided are a turbo fan and an air conditioner using the same. The turbo fan includes a main plate rotating by power provided from a fan motor, a blade having one end connected to the main plate to rotate, a shroud connected to the other end of the blade, and an orifice guiding a flow of indoor air in a direction of the shroud. The shroud includes a guide surface defining one surface of the shroud, the guide surface having a predetermined curvature and an air guide connected to a side of the shroud, the air guide being disposed in a direction of the orifice from the shroud.

Abstract: A ceiling type air conditioner includes a case defining an outer appearance, a fan disposed to a bottom of the case, a turbo fan disposed within the case, the turbo fan including a main plate rotated by power provided from the fan motor and a blade having a side connected to the main plate, and a heat exchanger disposed outside the turbo fan. A cooling passage cooling the fan motor is defined between the main plate and the bottom surface of the case. The cooling passage includes a flow part through which air passing through the blade flows into the flow part toward the fan motor, and a panel installation part to which a panel is installed for adjusting an amount of air flowing into the flow part toward the fan motor.
