UN APARATO DE PLACA DE COCINA VITROCERAMICA

摘要

A glass ceramic cooking appliance having at least two separately switchable or combined switchable heating elements has a thermal cutout preventing overheating of the glass ceramic surface. A single temperature sensor acts on the thermal cutout and the sensor is subject to the influence of all the heating means elements. To ensure that the operating temperature of the glass ceramic hotplate is as close as possible to the permitted permanent operating temperature, the cutout operating temperature is detuned as a function of the nature and number of heating elements switched on in order to compensate for different thermal influences. The temperature sensor can be an expansion sensor acting on a plurality of switches with different operating temperatures. Upon operating the heating elements a different switch is connected in series in each case to the individual heating elements.
