Abstract
PURPOSE: To improve precision of scorching by a method wherein a light sensor is shielded from food by a glass plate, and the heating products deposited on the surface of the glass plate are heated and decomposed by high-frequency energy, 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 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 the light sensor 11 are not polluted by the heating products of the food 3. In addition, a conductive film coat 15 is formed on the surface of the glass plate 14, and a high-frequency energy oscillator 6 and a waveguide 7 are provided, so as to heat and decompose the heating products deposited on the glass plate 14. Accordingly, precision of scorching can be improved.
