  • Patent number: 6744977
    Abstract: An electric heater with a heat shield plate includes a heating body which is installed at a reflector and heated when electrical power is applied thereto. A safety net is provided which covers a front surface of the reflector and defines a space for accommodating the heating body therein. Further, the heat shield plate is installed at an upper edge of the reflector such that foreign materials are prevented from falling down onto the heating body through the safety net, and a plurality of through-holes are dispersedly formed in the heat shield plate in order to prevent the heat shield plate from being overheated. The heat shield plate includes a curved strap-like plate in which the plurality of through-holes are dispersedly formed, and fixing pieces which extend vertically from the curved plate on one lateral side thereof so that they are coupled to the reflector.
