Abstract
A heater section for hair dryers utilizing spirally wound sinusoidally shaped electric resistance heating wire wound about a plurality of radially extending insulating mica boards. The mica boards are axially aligned along the external surface of a central frustoconical/cylindrical motor shroud disposed within a frustoconically shaped dryer housing and are provided with notches to hold the heating wire. A portion of the air moved by the hair dryer fan is blown past the heating wire between the interior surface of the dryer housing and the motor shroud and a portion is blown past the motor between it and the motor shroud. The apertures in the mica boards and the frustoconical/cylindrical motor shroud facilitate the circulation of heated air within the dryer housing. The frustoconical shape of the front portion of the motor shroud adjacent the hair dryer nozzle enhances turbulence within the heater section to facilitate more uniform temperature distribution at the nozzle of the hair dryer.
