Abstract

본 발명은 전자렌지의 소음저감에 관한 것으로, 특히 전자렌지의 구동시 인가되는 전압을 사용자가 전자렌지의 주변 상황에 따라 선택 조절함으로써 전자렌지 구동시 발생되는 소음을 저감시킬 수 있도록, 전자렌지 구동 회로에 있어서 출력조절 릴레이의 접점 선단과 팬 모터 사이 및 출력조절 릴레이의 접점 후단과 고압 트랜스의 일차측 사이에 상호 연동되어 팬모터 및 고압 트랜스의 입력 전압을 조절하기 위한 저감 릴레이를 설치하여, 조리 선택 후 시작 버튼을 누르면 외부 전환스위치가 정음 모드인가를 판별하여 정음 모드인 경우 저감 릴레이를 구동시킨 후 시작 릴레이 및 출력조절 릴레이를 구동시켜 조리가 완료될때까지 조리를 진행시키는 전자렌지의 소음 저감 회로 및 저감 방법에 관한 것이다.The present invention relates to noise reduction of a microwave oven. In particular, the user can adjust the voltage applied when driving the microwave oven according to the surrounding conditions of the microwave oven so as to reduce the noise generated during the microwave driving. In the circuit, a reduction relay for controlling the input voltage of the fan motor and the high-voltage transformer is installed by interlocking between the contact tip of the output control relay and the fan motor and the rear end of the contact of the output control relay and the primary side of the high-voltage transformer. Press the start button after selection to determine whether the external changeover switch is in the silent mode.In the silent mode, drive the reduction relay and then start the start relay and the output control relay to reduce the noise in the microwave oven. And a reduction method.
