ABSTRACT:
A wall-mounted hair dryer has a casing which contains a heating element, a motor, an impeller and associated electrical circuitry. There is a flexible air hose terminating in a handle having an outlet for directing hot air onto the person of a user. The handle can be secured detachably magnetically against the casing, and a switch is provided to switch on the hair dryer when the handle is detached from the casing and to switch it off when the handle is replaced. A electronic timer circuit is also provided to switch off the hair dryer after a predetermined period of operation. Two shaver outlets are mounted on the casing and are connected to a dual-voltage current-limited transformer supplying one of the outlets with mains voltage (e.g., 110 volts) and the other outlet with twice the mains voltage (e.g., 220 volts), with the current to the outlets being limited to 0.1 ampere by a current limiting device.
