Abstract

Bei einem Ausführungsbeispiel weist ein Kochfeld (11) eine Glaskeramikplatte (13) auf und eine Strahlungsheizung (18) darunter. Zwei Quotienten-Pyrometer (20a, 20b) sind im wesentlichen auf dieselbe Stelle an der Unterseite eines aufgestellten Kochgeschirrs (15) gerichtet. Sie sind jeweils auf einen Wellenlängenbereich eingestellt. Beim ersten Wellenlängenbereich ist die Transmission der Glaskeramikplatte (13) nahe null und beim zweiten nahe eins. So kann die Strahlungsintensität der Glaskeramikplatte (13) aufgrund eigener Erwärmung ermittelt werden und aus der Temperaturberechnung der Unterseite eines aufgestellten Kochgeschirrs (15) herausgerechnet werden.

In one embodiment, a hob (11) has a glass ceramic plate (13) and a radiant heater (18) underneath. Two quotient pyrometers (20a, 20b) are directed to substantially the same location on the underside of a raised cookware (15). They are each set to a wavelength range. In the first wavelength range, the transmission of the glass-ceramic plate (13) is close to zero and close to one in the second. Thus, the radiation intensity of the glass ceramic plate (13) can be determined due to its own heating and out of the temperature calculation of the underside of a set up cookware (15).
