Claims (1)

입력되는 교류전원(AC)을 감지하는 전원감지부(1)의 출력전압을 기준전압과 비교하여 정격전압보다 높은지를 검출하는 비교부(2) 및 정격전압보다 낮은지를 검출하는 비교부(3)에서 고전위가 출력됨에 따라 마이콤(4)의 10초 타이머(41)의 제어로 타이머(42)(43)가 그 비교부(2)(3)에서 고전위가 출력되는 시간을 측정하여 타이머(43)의 시간에서 타이머(42)의 시간을 감산하고, 그 감산된 시간을 가열시간 타이머(45)에 설정한 가열시간에 가산하여 마그네트론(5)을 구동시키게 하고, 상기 비교부(2)(3)에서 모두 저전위가 출력됨에 따라 상기 가열시간 타이머(45)에 설정한 가열시간으로 마그네트론(5)을 구동시키게 구성함을 특징으로 하는 전자레인지의 가열시간 제어장치.Comparing unit (2) for detecting whether the output voltage of the power detection unit (1) for detecting the input AC power is higher than the rated voltage and a comparison unit (3) for detecting whether the output voltage is lower than the rated voltage As the high potential is output from the timer under the control of the 10-second timer 41 of the microcomputer 4, the timers 42 and 43 measure the time at which the high potential is output from the comparator 2 and the timer 3. The time of the timer 42 is subtracted from the time of 43, and the subtracted time is added to the heating time set in the heating time timer 45 to drive the magnetron 5, and the comparison unit 2 ( The heating time control device of the microwave oven, characterized in that the magnetron (5) is configured to drive the heating time set in the heating time timer (45) as all low potentials are output in 3). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
