Abstract
A combination fan and heater with fan speed control operates to provide a cooling or heated flow of air at various desired temperatures and airflow speeds. A switch controls the operation of a heating assembly and a motor, to operate at a higher speed when the device is used as a cooling fan, and at a lower speed when the device is used as a heater. A baffle is included in the heating assembly to concentrate air flow in the center of a fan blade assembly, so that only a portion of the airflow produced by the fan blade assembly actually flows through the heating assembly.
