High efficiency induction cooking-range with monoconductor heating coil

摘要

The disclosed induction cooking range comprises, in the commonly known way, an upper plate made of glazed ceramic designed to receive a receptacle to be heated made of ferrite material, a monoconductor induction coil positioned beneath the upper plate on a coil support and excited by a high-frequency current generator. The induction coil is allowed to heat by its own losses to a temperature greater than that of the receptacle and the induction coil communicates its own heat to the receptacle. The overall efficiency of the range is thus appreciably increased. The induction coil, which must then tolerate a high temperature, is made out of a flat, monoconductor strip placed between two sheets of mica.
