Abstract
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.

An induction cooking range comprising an upper plate made of a ceramic material 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, wherein the monoconductor induction coil comprises a flat conductive strip having dimensions wound in a spiral and separated from the upper plate by a thermally conductive electrically insulating thin sheet having a top surface and a bottom surface for conducting thermal heat from said induction coil to said receptacle, and wherein the top surface directly contacts said upper plate and the bottom surface directly contacts said monoconductor induction coil.
