<p>The invention relates to a heating device, which comprises: a substrate; a ceramic layer covering the substrate; electric heating means; detection means for detecting the temperature; and a control circuit for controlling the heating means on the basis of the temperature detection, wherein the heating device is distinguished in that the heating means are formed by at least one resistance strip which is arranged on the ceramic layer. Another property of a heating device according to the present invention is that it contains at least two separate areas which are controlled by the control circuit and which each have at least one resistance strip and detection means. In a device according to the invention the heating means and the detection means are arranged very close to the surface to be heated and close to each other, whereby the control circuit can bring about very rapidly the required changes in the temperature of the surface to be heated of the heating device. It is likewise no longer necessary to cause a grill plate formed by the heating device according to the invention to function continuously, since the response time of the temperature control is very short. <IMAGE></p> |
