Abstract

PURPOSE: To perform the positive sensing of the scorch of a food being cooked by a method wherein a light receiving element is arranged at the outside surface of a ceiling of a heating chamber through a mechanism for performing a thermal shut-off and cooling operation.
CONSTITUTION: Light receiving element 12 is arranged at the outside surface of a ceiling of the heating chamber at an axis passing vertically through a substantial central part of the heating chamber 1 in such a way as it corresponds to the foodstuff placed substantially at the central part in the heating chamber 1. Blower fan 21, duct 21a, and heat insulative material 15 form a thermo shielding and cooling mechanism 21b for the light receiving element 12. As a surface of the foodstuff 3 is scortched, a luminance of reflected light sensed by the light receiving element 12 is gradually decreased. When the luminance is reached up to the predetermined value, a signal is transmitted to a power supply 26 and the operations both the electric heaters 5a to 5d and the lamp 9 are terminated.
