Heating apparatus and heating power control method

Abstract

A heating apparatus by heating cooking materials in a water contained pan includes a heating device and an electronic circuit which controls the heating device. The temperature of the pan is detected, and the temperature rise characteristics of the pan contents are detected from when heating the pan starts until the contents boils. The quantity of the contents being cooked is determined from the temperature rise characteristics at a relatively low temperature range. The type, such as the size of the contained solids, of the contents being cooked is determined at a relatively high temperature range near the boiling point. The heat output of the heating device is then regulated based on these determinations according to the selected cooking operation after the materials boil, and the cooking apparatus thus provides automated cooking control.
