ABSTRACT:
A heating element assembly for a ceramic top electric range is disclosed. The assembly includes a base pod comprising a block of insulating material having a recess in one surface. A grooved path is formed in the recess in the form of a spiral and a thin, flat strip of apertured, foil-like, electrical resistance material is inserted in the grooved path. That strip is only partially received by the groove so that a major portion of its width projects toward but not beyond a plane defined by the face of the block. Electrical terminals are provided at the ends of the strip and the block is adhered to the bottom surface of the ceramic top to encapsulate the heating element.
