Abstract
A portable electric hair dryer wherein the tubular part of the housing has an inlet for atmospheric air and an outlet for heated air. The housing confines an electric motor for an impeller which induces the flow of air from the inlet toward the outlet, and an electric heater for the flow of air. The motor is surrounded by annular first insulating carrier of electric contacts which are connectable to an energy source, and the heater has a second insulating carrier for contacts which are separably connectable with the contacts on the first carrier and serve to supply energy to the heater. The first carrier has surfaces which engage adjacent surfaces on a stationary air guide having a socket for the motor behind the first carrier. The contacts on the first carrier can include flat plugs which are receivable between pairs of elastic prongs constituting the respective contacts on the second carrier, or vice versa.
