Abstract
An electronic range wherein a digital value showing the quantity of food being cooked is set and indicated by a food quantity-setting device; another device is provided to select the kind of food being cooked; the period of pulses generated by a pulse generator is determined by an output from said selection device; pulses emitted by the pulse generator are counted upon commencement of a food-heating operation; the counts made by the counter are indicated in the form of digits; and heating by the electronic range is brought to an end when a prescribed relationship arises between the counts made by the counter and the previously set value denoting the quantity of food.
