ABSTRACT:
The housing of a blow dryer has a slender handle shaped to be held in the hand and formed with a pair of windows on the back side, and a large head formed with an outlet. A blower motor is mounted in the handle and carries a fan in the head which blows air past a heater through the outlet. A control circuit housed in the handle is connected to a pair of control elements mounted rotationally on the motor casing and operable through the windows at the back of the handle. One of these controls varies the motor speed and the other establishes the output temperature. The two adjustment members are rotatable about the motor axis, with the temperature-adjustment member formed with teeth connected to a gear carried on a potentiometer and the motor-speed adjustment member connected via an axially extending finger to a motor-speed switch.
