Abstract

An apparatus is provided to control the cooking process in a pressure cooker heated by an electrical heating element. By measuring values related to the temperature-time characteristic curve during the heating up phase, the cooking system is operated in an energy saving manner utilizing the inertia of the system by switching off the heating element prematurely to maintain the desired cooking time. By providing an additional mode of operation, the cooking process can be carried out in several successive cooking phases while still providing the energy saving feature of prematurely switching off the heating element in all cooking phases.
