Abstract

PURPOSE: To improve precision of scorching cooking by a method wherein a light sensor is shielded from food by a glass plate, and the deposites on the glass plate are incinerated and blown away by air, in a cooker which detects the scorch optically.
CONSTITUTION: In a heating chamber 1 are provided electric heaters 5aW5d for heating and scorching food 3, a lamp 9 for projecting visible light onto the food 3, and a light sensor 11 for detecting the reflected light. The electric heaters 5aW5d are controlled when the amount of reflected light reaches a setpoint. A heat-resisting transparent glass plate 14 is so arranged that the lamp 9 and light sensor 11 are not polluted by heating products of the food 3. In addition, an electric heater 15, a blower 19 and blowing pipe 24 are provided to incinerate the deposites on the glass plate 14 and blow them away by the air flow. Accordingly, precision of optical detection is improved and hence precision of scorching is improved.
