As described above, in case that the family firstly heats the food and all of the family are eating on time, there is a slight difference in time, and when some of the remaining persons eat, the food is already cold, The present invention is characterized in that the power of the electric range is automatically turned on after a lapse of a predetermined time, and a warming function for warming the food with a constant thermal power, preferably a minimum thermal power, is added to the food remaining after the first heating, Allow food to be enjoyed. Such a warming function can be operated by operating a function key indicated by warming or warming on one side of the control part of the electric range.

The time for performing the warming or warming function may be such that when the time for warming the secondarily warmed food to the firstly boiled food is given indefinitely, it may happen that the user sometimes goes out without knowing that the electric range is turned on. Therefore, In order to make it usable, it is necessary to limit the warming time (keeping time) within a certain time.

In this case, the warming function is performed with a minimum thermal power for the boiled food, and the time given to the warmed food is limited within a predetermined time, and when the temperature is exceeded, the power is automatically turned off.

In this way, according to the present invention, the boiled food is heated by a separate warm-keeping key so that the food is boiled once, and the food is kept warm by the minimum thermal power so that the remaining family can eat the warm food.
