A flexible bonnet portable hair dryer including two separate combination blower and heater units. A flexible U-shaped collar support is connected to the combination blower and heater units and to a lower edge of the bonnet.

Portable hair dryer

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.

Hand-held blow dryer with thumb-operable controls

A hair dryer comprising a generally tubular housing including twogenerally semi-cylindrical grip parts having edges including complimentary grooves and projections which engage each other to secure the grip parts together, the housing accommodating a heating device, a motor and an air transport device therein, a first end grid which is mounted over an intake opening on one end of the housing to secure the grip parts to the first grid as well as to each other, and a second end grid mounted over an exhaust opening at the other end of the housing to secure the semi-cylindrical grip parts to the second grid as well as to each other.
