Abstract

PURPOSE: To control the microwave heating output and uniformly heat food, by utilizing a fixed relation between the central temperature and the peripheral temperature of the food.
CONSTITUTION: When a temperature setting unit 2 is set at an optional temperature and a power switch is turned on, the output of a temperature comparator 3 goes to a high level because the temperature of a thermistor 1 is lower than the set temperature. At that time, a time detector 4 starts counting. Since the counted time is shorter than a set time, the output of a time comparator also goes to a high level. In addition, the inputs A, B of a gate 7 go to a high level. An AC control element is turned on by the output of the gate 7 through a driver 8 to cause a magnetron to oscillate. When the temperature detected by the thermistor 1 has reached the set temperature, the output of the temperature comparator 3 is inverted to a low level. Then, the magnetron stopo oscillating and the counting by the time detector 4 is stopped because of the output inversion of the temperature comparator 3.
