Abstract
A hair dryer has an electric heating element adapted to produce any desired intensity of heat output within a continuous range of heat intensities and an electric blower adapted to produce any desired speed of air flow within a continuous range of air flow speeds which is then heated by intensity of the heat output of the heating element to produce any desired heated air flow output. The hair dryer also has a control circuit electrically connected to the heating element and blower and being operable upon actuation by a pair of momentary switches to simultaneously regulate operation of the heater element and blower to produce a continuously variable heated air flow output. The continuously variable simultaneous regulation of the heat output intensity and air flow output speed is driven or powered in opposite directions by a user manually manipulating the pair of momentary switches respectively labelled 'Up' and 'Down'. The longer the period of time that the 'Up' momentary switch is pressed by the user, the more the intensity of heat output and the speed of air flow output are increased. The longer the period of time that the 'Down' momentary switch is pressed by the user, the more the intensity of heat output and the speed of air flow output are decreased.
