Abstract
A variable-size induction heating plate includes a plurality of windings (10a, 10b, 10c, 10′a, 10′b, 10′c) arranged in a cooking surface. The heating plate includes two sets (10, 10′) of a plurality of windings arranged side-by-side, each set (10, 10′) of windings being adapted in such a way as to form a heating plate, and control elements (12, 12′, 13) which are adapted in such a way as to control the operation of the sets (10, 10′) both in an independent manner and a synchronous manner. Each set of windings is fed by a single current generator (11, 11). The inventive heating plate can be used in an induction cooking surface.
Claims23
A variable-size induction heating plate comprising:
- at least two sets of a plurality of windings disposed side by side in a plane, the windings of each set being electrically connected in series to each generator, the at least two sets including
- a first set constituting a first heating section, all the windings of said first set being tangential to a circle corresponding to a first heating plate, said first set being supplied with power from a first single current generator, and
- a second set constituting a second heating section, all the windings of said second set being tangential to a circle corresponding to a second heating plate, said second set being supplied with power from a second single current generator;
- a first controller adapted to independently control said first set;
- and
- a second controller adapted to independently control said second set, the first and second controllers being adapted to control said first set and said second set in synchronous operation upon said first and second sets constituting a single heating plate, all the windings of said first set and said second set being tangential to an ellipse corresponding to said single heating plate.
