Abstract

This invention relates to controlling the simmering or cooking time in a cooking vessel which can be heated by means of an electrical cooking plate with a control circuit, in which the temperature in or on the cooking vessel is determined and utilized by the control circuit to regulate the heat output of the cooking plate, in which the simmering or cooking time can be set by means of an adjustable time element, in which the cooking plate can be shut off at a length of time bvefore the completion of the predetermined simmering or cooking time which is greater the slower that the rise of the temperature in the heating phase is, and in which, by using the heat content contained inthe cooking material after shutting off the cooking plate the simmering or cooking process is extended up to the preset simmering or cooking time. Starting temperatures which lie above room temperature distort the increase of the temperature in the heating phase, and thus the derivation of a measuring value initiating the premature switching off of the cooking plate. This invention provides for correcting the measure values in the heat phase in a predetermined manner so that the cooling process can nonetheles…
