Abstract

PURPOSE: To secure detection of scorch of food by a method wherein a window is provided between the object to be heated and a combination of a light source and a light sensor, and an air passage is provided at the window, in a device whih performs a scorch control through utilization of changes in reflection factor attendant on the heating of the surface of the object to be heated.
CONSTITUTION: A lamp 9 projects visible light on food 3 through a partition plate 18 and a glass plate 14, and a blower 20 blows air as indicated by dotted-line arrow. A light sensor 11 detects the light reflected from the surface of food, through the glass plate 14 and the partition plate 19. When the intensity of illumination detected by the sensor 11 falls to a predetermined value, cooking is completed. Since oil or the like coming from the food 3 is blown by the air flowing by the surface of glass and does not adhere to the glass plate 14, the sensor 11 always performs correct detection and the control of scorching cooking is conducted precisely.
