Claim 9:
10. A detection device for operating a heating element, in particular in a food processor for at least partially automatic preparation of foodstuffs, comprising:
a voltage measuring device for measuring an electric voltage at the heating element,
a current measuring device for measuring an electric current at the heating element,
an evaluation device for detecting an electrical resistance in the heating element by evaluating detection values of the voltage measuring device and the current measuring device, such that at least one resistance value can be determined in order to provide the at least one resistance value for a temperature-dependent heating operation of the heating element,, wherein the currently detected electrical resistance, which is specific for the electrical resistance of the heating element, is directly serving as a basis for the temperature-dependent heating operation.
