  • Patent number: 5243682
    Abstract: A wall mounted hair dryer, having a stationary heated air supply, a portable dryer head and a flexible hose connecting the two, is provided with an isolated heater element which controls the temperature gradient profile of the discharge conduit of the air supply unit, thereby maintaining a hot central core surrounded by a relatively cool blanket of air. Consequently, the components of the air supply unit, the coupling hose and the dryer head may all be constructed of economical plastics without component failure due to heat degradation.
