Patent Images
1. A cooker comprising:
- heating means for heating food material in a container,temperature measuring means for measuring temperature of outer face of the container, and issuing temperature signals,heat amount control means for controlling amount of heat issued from the heating means anda heat control circuit part for issuing a control signal to be given to the heat amount control means based on said temperature signals input thereto,said heat control circuit part comprising temperature gradient signal generator means for producing signal of temperature gradient from the input temperature signal, bending point detector means for detecting bending point of the temperature increase and issuing a detection signal and heat control signal generator for outputting the control signal for the heat amount control means basing at least on output of the bending point detector.

Abstract
A highly automationed cooking apparatus especially suitable for stew cooking or the like liable to boiling over. Temperature of outer bottom face of a pan is measured by a sensor and temperature gradients are sampling-measured at a sampling time pitch. Boiling point of food material is detected by finding a decrease of the temperature gradient, and thereafter the heating is lowered to avoid boiling over to a suitable value which is given by processing the temperature gradients.
