  • Patent number: 4309593
    Abstract: An electric heater construction which significantly reduced the possibility of electrical shock to a user thereof. This electric heater includes an outer casing with an open front, a protective grille mounted over the open front of the outer casing, a reflector assembly mounted within the outer casing and a heating element enclosure mounted to the reflector assembly such that it is electrically insulated therefrom. A ribbon-type of heating element is mounted within the heating element enclosure. If any portion of the heating element should break or for any other reason become disengaged from the insulated mounted structure, the heating element enclosure effectively prevents it from coming in contact with any non-insulated portion of the device which is readily accessible to a user of the heater thereby protecting a user of the device from electrical shock.
