ABSTRACT:
A portable electric hair dryer wherein the insulating carrier of electric contacts for a motor which drives an air impeller between the air-admitting inlet and the air-discharging outlet of the housing is separably coupled to a second insulating carrier which is provided with electric contacts for and supports an electric heater. The latter heats the flow of air between the inlet and the outlet of the housing. One of the carriers has male coupling elements, which can include or constitute the contacts on the one carrier, and the other carrier can have female coupling elements, which can include or constitute the contacts on the other carrier, capable of separably receiving and retaining the male coupling elements.
