A combined electric fan and radiation heater, selectively used as an electric fan in summer and as an electric radiation heater in winter, is disclosed. The combined fan and heater of this invention consists of a fan motor set in a motor case, a parabolic rear safety net, a blade unit, and a parabolic front safety net in the same manner as a conventional electric fan. The combined fan and heater is also provided with a parabolic reflector and a heat radiating body. The parabolic reflector is designed to be detachably attached to the front end surface of the motor case using a nut while replacing the rear safety net. The heat radiating body is externally wound with a heating coil and is designed to be detachably held on a seat of the parabolic reflector prior to being attached to the front end surface of the motor case using a plurality of locking screws while replacing the blade unit, with the heating coil being operated in conjunction with an existing electric circuit. When the combined fan and heater is used as an electric radiation heater, the heater accomplishes a desired radiation heating effect, allowing strong heat to effectively reach an area considerably remote from the heater, due to the parabolic reflector. |
