HEATING DEVICE AND METHOD FOR OPERATING A HEATING DEVICE

摘要

A heating device for a cooking point in a hob has three independent and separate long heating elements which are arranged on a support of the heating device along concentric circles. The support has a central region around the centre point, an outer region adjoining an outer edge, and an intermediate region between the central region and outer region. A rod-type thermostat engages over the heating device for the purpose of temperature detection. The first and the third heating element are connected to an energy supply over the rod-type thermostat. A second heating element is connected to an energy supply without interconnection of the rod-type thermostat, wherein the second heating element is arranged on the support in the central region, in the intermediate region and in the outer region.

主权项

1. A heating device for a cooking point in a hob, wherein said heating device comprises:
a plurality of independent and separate long heating elements which are arranged on a support of said heating device in loops or in a spiral manner or substantially along concentric circles, wherein said support has at least a central region around a centre point and an outer region adjoining an outer edge, wherein a width of said central region and of said outer region is approximately equal, wherein said heating elements run on said support so as to engage one in the other and cover a significant area of said support, wherein an overtemperature protection means engages over said heating device or said support for purpose of detecting a temperature at said heating device, wherein at least a first heating element is connected to an energy supply means by means of said overtemperature protection means in order to switch off said first heating element in an event of an overtemperature, wherein a second heating element is connected to an energy supply means without interconnection of said overtemperature protection means or another overtemperature protection means, and wherein said second heating element is arranged on said support in said central region and in said outer region.
