INDUCTION HEATING COOKING UNIT

摘要

PURPOSE:To improve reliability in communication by making it hard to be influenced by noise caused by an induction heating part in an induction heating cooking unit to carry out the communication. CONSTITUTION:An induction heating cooking unit is provided with a zero voltage detecting means 3 to detect zero voltage of AC electric power supply, modulating means 53 and 63 which code an output signal of an induction heating part control means 50 or a mode control means 60 into a digital signal having the prescribed digit number and output a single digit of the digital signal according to output of the zero voltage detecting means 3 until it passes through a zero voltage point and reaches the next zero voltage point and hold the content of output until it passes through the vicinity of the next zero voltage point and demodulating means 54 and 64 which input a signal in the vicinity of the zero voltage point according to the output of the zero voltage detecting means 3 and demodulate the digital signal after a signal is inputted up to the prescribed digit number.
