ABSTRACT:
An induction cooking heater comprises an inductor, an inductor support comprising a magnetic material and a protective sheet positioned beneath the support in contact with this support. The support is made of a thermally conductive, electrically insulating material to enable the discharge of calorific energy from the inductor to the protective sheet. Furthermore, with the inductor taking the form of a strand of electrically conductive wires in spiral form, the support has a housing on its upper face that is also spiral shaped, adapted to receiving said strand and improving the thermal transfer.
