A variable-size induction heating plate includes a plurality of windings () arranged in a cooking surface. The heating plate includes two sets () of a plurality of windings arranged side-by-side, each set () of windings being adapted in such a way as to form a heating plate, and control elements () which are adapted in such a way as to control the operation of the sets () both in an independent manner and a synchronous manner. Each set of windings is fed by a single current generator (). The inventive heating plate can be used in an induction cooking surface.

Variable-size induction heating plate

A method for heating a container (Ri) placed on a cooktop including heating elements which are associated respectively with inductors which form elements for detecting the presence of the container and are distributed along a frame which is embodied such that it is two-dimensional in a cooking area. The method includes searching (E) a heating area (Zi) having the heating elements arrangement which are at least partially covered by the container and computing (E) a power supplied by each heating element of the heating area (Zi) according to a total specified power (Pi) associated thereto and the degree of coverage of each detection element associated to heating element by the container (Ri). Utilization, in particular, is for an inductive cooktop.

Method for heating a container (Ri) placed on a cooktop including heating elements which are associated respectively with inductors which form elements for detecting the presence of the container and are distributed along a frame which is embodied such that it is two-dimensional in a cooking area. The method includes searching (E) a heating area (Zi) consisting of the heating elements arrangement which are at least partially covered by the container and computing (E) a power supplied by each heating element of the heating area (Zi) according to a total specified power (Pi) associated thereto and the degree of coverage of each detection element associated to heating element by the container (Ri). The invention can be used, in particular for an inductive cooktop.

An induction heating device for heating cooking vessels includes at least three concentric inductors and implements a step of heating a load. For a load covering at least three inductors, at least one intermediate inductor that is covered and that is determined in such a manner as to homogenize the input of heat to the load is not energized during the heating step. Applications of the device include domestic hot plates.
