  • Patent number: 4195416
    Abstract: A cabinet adapted to be mounted on a wall of a washroom or similar facility is provided with a conventional hand-held hair dryer secured within the cabinet and positioned so that the output of the hair dryer is projected through a vent opening in the cabinet. The hair dryer is controlled by a push-button time switch and the push button of the switch is operable from the outside of the cabinet. A suitable vaporizing substance is disposed within the cabinet adjacent to the inlet of the hair dryer so that the fumes are expelled through the vent together with the heated air. Additional electrical circuitry can be provided to override the time switch and to provide power outlets for washroom accessories such as electric shavers or lighting.
