  • Hair dryer
    Patent number: 4196343
    Abstract: A hair dryer of the hand-held variety has infinitely variable temperature and fan speed control. The fan speed control is trigger operated by the index finger while the heat control is thumbwheel actuated by the thumb. Neither control, once set, requires any further action such as holding in place to maintain the desired setting. By location of the controls in this fashion, surprisingly easy and efficient one-handed overall control of the hair dryer is possible.
