Electric hot plate

Claim 1

An electric cooking stove assembly comprising a glass plate, a convoluted molybdenum disilicide electric resistance heating wire forming a layer of interspaced convolutions substantially parallel with and spaced below said plate and having ends for connection with electric power, a refractory fibrous pad positioned below and completely free from contact with said layer and having a flat top surface substantially parallel with said layer, and means for supporting said layer so that when hot it radiates heat upwardly both directly and by reflection from said fibrous pad, the molybdenum disilicide wire of said element having a diameter and length which causes the wire to heat to temperatures substantially above 2000° F. when electrically powered at its rated voltage and at least the pad's said top surface having a substantially white color causing appreciable diffused reflection of thermal energy having wave lengths inherent to said temperatures, said means comprising interspaced support wires having lower ends stuck in said fibrous pad, said support wires extending straight upwardly from the pad's said top surface, said wires having upper portions spaced above said pad and forming loops in which said molybdenum disilicide wire is positioned and thereby supported, said support wires having diameters no greater than said diameter of said molybdenum disilicide and made of metal alloy of the Fe-Cr-Al type and having an oxide coating protecting against reaction with said element.
