Abstract
In the case of a method of pot detection at a gas cooking point with a gas burner, a thermocouple is fitted at the gas cooking point for flame sensing, to be precise in such a way that with every output of the gas burner possible for a sustained period it is impinged by the flame. In order to detect whether a pot has been placed onto the gas cooking point while the gas burner is in operation or whether the pot has been taken away, the thermoelectric voltage is tapped at the sensing means and evaluated by a comparison of the signal at the time with the signal in the case where a pot has been placed on. A different flame prevails at the thermocouple when a pot has been placed on than when the pot has been taken away, and the temperature is different. The output at the gas cooking point is reduced as a reaction to detection of the taking away of the pot.
