Abstract
PURPOSE: To control the degree of scorch automatically and appropriately by providing a light source irradiating visible rays and a light sensor detecting reflected light to stop heating by the signals of the light sensor and providing a means to change heating forms and a means to correct preset values.
CONSTITUTION: When a power source device 16 is driven, a lamp 10 lights and irradiates a heated object 3, reflected light from it is sent to a light sensor 14 and a control device 15 memorizes illuminance from the heated object 3. On the other hand, hot air is supplied to a heating chamber 1 and the heated object is heated. If the surface of the heated object 3 begins to be burnt, the illuminance detected by the light sensor 14 lowers and when this value reaches a predetermined value, the control device 15 sends a signal to the power source device 16, then the power source device 16 stops the operation of heaters 5, 5' and a fan 9 and drives a high frequency oscillator valve 6. By so doing, the heated object 3 is heated, and after a certain time, the operation of the high frequency oscillator valve 6, a motor 8 and the lamp 10 is stopped.
