TEMPERATURE CONTROL METHOD OF ELECTROMAGNETIC COOKER

PURPOSE:To control the temperature at a constant value always, by providing a control device to control the output of a heating coil depending on the data of a detecting sensor to detect the temperature of a substance to be heated, and correcting a set temperature according to the temperature rising speed of the sensor. CONSTITUTION:When a control device 16 detects the switch ON, it feeds a specified output to a heating coil 14. And the control device 16 compares the detecting temperature of a sensor 13, and a specified temperature programmed beforehand, and when the detecting temperature reaches to the specified temperature, it measures the temperature rising speed. This measuring can be calculated by measuring the time necessary to rise a specific temperature. When the distance between a substance to be heated 15 and a top plate 12 is increased by a deformation of the substance 15 and the like, and the temperature rising speed is slow, the detecting temperature of the sensor 13 is made higher than the actual temperature of the substance 15. Consequently, the set temperature of the sensor 13 is corrected to a lower value. As a result, constant temperature control can be carried out constantly.
