Abstract
An electric hair dryer wherein a collapsible hood defines one or more plenum chambers for heated air and has a foraminous inner panel which is adjacent to the hair when the hood is placed over the head of the wearer. The hood has a hollow extension which is adjacent to the chest of the wearer and is separably connectable with the slotted detachable cover of a housing for the electric motor which drives a rotor for supplying heated air into the plenum chamber or chambers. The rotor is installed in the cover and is disposed downstream of an air heating unit which is mounted in the interior of a hollow cylindrical or frustoconical air guide and surrounds a tube for admission of cool atmospheric air into the space around the motor. The bottom wall, the front wall and the two lateral walls of the housing are formed with ports which admit atmospheric air into the air guide as well as into the tube.
