  • Heat cooking apparatus with controllable heat source
    Patent number: 5457302
    Abstract: A heat cooking apparatus includes a gas burner, and a temperature sensor for sensing a food correlative temperature. A microcomputer determines a category of the food on the basis of a time necessary for raising a temperature of the food by a predetermined temperature, and sets a termination temperature according to the category. If the time is more than a predetermined value, the microcomputer determines that the food is "boiled food", and sets a boiled food termination temperature. If the time is less than a predetermined value and a temperature drop occurs during temperature raising, the microcomputer determines that the food is "fried food", and sets a fried food upper limit temperature. If the time is less than a predetermined value and no temperature drop occurs during temperature raising, the microcomputer determines that the food is "deep-fried food", and sets a deep-fried food upper limit temperature.
