Abstract

PURPOSE: To avoid malfunction by preventing a high-frequency circuit from following up the short period change of the signal level of temperature detection in the vicinity of a set value thereof.
CONSTITUTION: Upon the fixed temperature control of a material to be heated, the second terminal 7c of a select switch 7 is chosen and a temperature detector 12 is placed in said material to be cooked 1. Next, cooking temperature and time are set to the desired values thereof by a setting means 16 and a timer signal generator 10 respectively. Initially upon heating, continuous output is generated by an AD convertor 15, the setting of a flip-flop 19 is retained, a both-directional thyristor 6 turns on, and a high-frequency oscillator continues "on" since the temperature of said material is low. Even though any short period change in voltage of power supply or the like has occurred to an amplifying circuit 14, there is a small probability that AND may be established between the pulses from a trigger pulse generator 8 and the short period change of said AD convetor 15 so that output is emitted from a second AND gate 17 and the effects of noise for example is eliminated.
