Abstract
본 발명은 다기능 전자레인지의 히이터 구동에 관한 것으로, 입력전압을 마이콤으로 감지하여 히이터를 제어하는 것을 기술적 과제로 한다.The present invention relates to a heater driving of a multi-function microwave oven, and to control the heater by sensing the input voltage to the microcomputer as a technical problem.
따라서 본 발명은 별도의 전압절환장치를 사용하지 않고 입력되는 전압레벨을 따라 히이터에 전압을 인가하는 방식을 달리하여 110V/220V에서도 동일한 히이터 구동 출력을 인가하는 것을 요지로 한다.Therefore, the present invention is to apply the same heater drive output even at 110V / 220V by changing the method of applying the voltage to the heater according to the input voltage level without using a separate voltage switching device.
또한 본 발명은 다기능 전자레인지에서 히이터 구동을 제어하는 것을 용도로 한다.In addition, the present invention is to control the heater drive in the multi-function microwave oven.
