AN INDUCTION HEATING DEVICE

摘要

An induction heating device having two superimposed conductors is provided, comprising a first conductor having a first electrically conducting pattern (111); a second conductor having a second electrically conducting pattern (121); wherein the first electrically conducting pattern (111) and the second electrically conducting pattern (121) are: i) connected to an alternating current in use; ii) superimposed thereby resulting in at least one section where the first electrically conducting pattern overlaps the second electrically conducting pattern; and iii) separated by at least a space arranged for accommodating material with an electrically conducting layer, wherein when the alternating current is supplied, the alternating current in the first electrically conducting pattern in a specific section has the same direction as the alternating current of the second electrically conducting pattern in said section.
