Abstract
Radiant heating apparatus (10) for use on a stove (1). The heating apparatus is mounted beneath a glasstop type cooking surface (2) for radiating heat at the surface to heat the surface for cooking food. A pan (14) is installed adjacent an underside (2u) of the cooking surface. A liner (30) formed of an insulation material is installed in the pan. An electrical heating element (32) is supported atop the liner. The heating element is formed of a strip (34) of an electrically resistant foil material to which an electrical current is supplied. The strip is a corrugated strip of foil laid upon an upper surface (36) of the liner in a predetermined pattern for heat generated by the heating element to be radiated directly at the cooking surface. A staple (42) secures the heating element to the liner. A temperature sensitive element (48) controls current flow to the heating element, and cuts-off current flow if the temperature exceeds a predetermined level. Installation of a corrugated strip heating element on the liner and securing the heating element such that it can flex when a current is supplied to it, without permanently distorting the strip, effects a maximum heat transfer to the cooking surface using energy directly radiated from the heating element.
