An apparatus for monitoring the cooking process in a cooking vessel placed on an electric heating element, particularly a stovetop burner, comprising signal transmitter controlled by the temperature in the cooking vessel, a signal receiver in communication with the signal transmitter by a transmitter for activating a control circuit to adjust the heat output of the heating element, and a switch for turning the apparatus on and off. During the entire cooking operation and when the heating element is set at full heating capacity, a periodical surveillance is effected to determine whether the temperature varies, remains steady or decreases. If a temperature increase is measured during a monitoring cycle, the heating element is not turned off, but if the temperature remains constant or falls, the heating element is turned off.

Apparatus for controlling an electric heating element (HE) for a cooking vessel, comprising: a signal transmitter means (TF) responsive to a temperature sensor means on said cooking vessel measuring the temperature in said cooking vessel; a signal receiver means (TE) in communication with said signal transmitter means (TF); a control circuit means (St) capable of controlling the heat output of said heating element (HE), said control circuit means (St) being capable of monitoring said heating element (HE) during successive monitoring cycles when a first switch means (S) is activated and determining at the beginning of each said monitoring cycle whether said heating element (HE) has been specified to full capacity heat output said control circuit means monitoring said successive monitoring cycles both when said full capacity heat output is and is not specified; a temperature differential circuit means (D) activated by said control circuit means (St) when said full capacity heat output is specified to determine a temperature differential during each said monitoring cycle when said full capacity heat output is specified whereby a first temperature value (Ta) measured by said temperature sensor means at the beginning of each said monitoring cycle is stored in a memory means (SPa) and a second temperature value (Te) measured by said temperature sensor means at the end of each said monitoring cycle is stored in a memory means (SPe) and said first and second temperature values (Ta) and (Te) are compared; and a second switch means (A) activated by said temperature differential means deactivating said heating element when said first and second temperature values (Ta) and (Te) are the same and when said second temperature value (Te) is less than said first temperature value (Ta).
