Abstract

본 발명은 전자렌지의 조리 동작을 제어하는 구동 장치에 관한 것으로, 특히 전자렌지의 동작시 전자렌지 구동용 메인 릴레이와 서브 릴레이의 동작을 일정 주기 이상의 간격을 두고 구동시킴으로써 전자렌지의 동작 초기에 발생하는 돌입전류를 자동으로 제어할 수 있도록, 전원이 입력되면 릴레이 동작시간 카운터에 릴레이 동작시간 평균값인 13을 세팅시킨 후 시작키를 입력시키고, 메인 릴레이 동작 카운터를 0으로 클리어시켜 위상각 0°에서 메인 릴레이를 턴-온시킴과 아울러 그 동작 시간을 메인 릴레이 동작 카운터에 기록하며, 메인 릴레이 동작 후 일정 주기 이상의 간격을 두고 서브 릴레이를 턴-온시킴과 아울러 그 동작 시간을 릴레이 동작시간 카운터에 기록하고 전자렌지를 동작시켜 릴레이 종류에 관계없이 돌입전류를 방지할 수 있도록 제어하는 전자렌지의 돌입전류 자동 제어 방법에 관한 것이다.The present invention relates to a driving device for controlling a cooking operation of a microwave oven. In particular, the operation of the microwave driving main relay and the sub relay during the operation of the microwave oven at a predetermined interval or more by driving the operation occurs at the beginning of the microwave oven In order to control the inrush current automatically, set the average value of relay operation time to 13 in the relay operation time counter when the power is turned on, and then enter the start key, and clear the main relay operation counter to 0 to set the phase angle at 0 °. Turn on the main relay and record its operation time in the main relay operation counter, turn on the sub relay at regular intervals after the main relay operation, and record the operation time in the relay operation time counter. To prevent inrush current regardless of relay type It relates to a method for automatically controlling the inrush current of the microwave oven to control.
