Abstract

본 발명은 전자레인지의 동작시에 발생되는 다양한 소음을 간섭음을 발생시켜 제거하는 전자레인지의 소음제거장치에 관한 것이다. 본 발명의 전자레인지의 소음제거장치는 크게 전자레인지의 동작 중에 발생하는 각종 소음을 수집하고 대응되는 전기신호로 변환하는 수단(14), 상기 변환된 전기신호의 주파수, 위상 및 진폭을 분석하고, 반대위상 및 동일진폭을 가지는 간섭음에 대응되는 전기신호를 발생시키는 수단(21) 및 상기 발생된 전기신호를 음성신호로 변환하여 출력하는 수단(15)을 구비한 것을 특징으로 한다.The present invention relates to a noise reduction apparatus of a microwave oven for removing various noises generated during operation of the microwave oven by generating interference sounds. The noise reduction device of the microwave oven according to the present invention comprises a means for collecting various noises generated during the operation of the microwave oven and converting them into corresponding electric signals, analyzing the frequency, phase and amplitude of the converted electric signals, And a means (15) for generating an electric signal corresponding to the interference sound having an opposite phase and the same amplitude, and a means (15) for converting the generated electric signal into a voice signal and outputting the sound signal.
