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.
Claims13
An induction cooking heater of the type comprising at least one inductor, an inductor support comprising a thermally conductive and electrically insulating material having magnetic properties, and a protective sheet positioned beneath the support, in contact with the lower face of the support, wherein the inductor has a strand of divided electrically conductive wires wound in the form of a spiral, the support comprising, on its upper face, at least one spiral-shaped housing adapted to the receiving of said strand so as to optimize the transfer of heat between the inductor and the protective sheet.
