Abstract

본 발명은 전자렌지의 흡기댐퍼 개폐장치의 관한 것으로, 종래 흡기 댐퍼 개폐제어회로는 스위치수가 많고, 그 결선이 복잡하여 댐퍼조립성 떨어지고, 고장발생률이 높은 단점이 있었다.The present invention relates to an intake damper opening and closing device for a microwave oven, and a conventional intake damper opening and closing control circuit has a number of switches, a complicated connection thereof, and thus, a damper assembly is inferior and a high occurrence rate of failures.

본 발명은, 이를 감안하여 구동모터(150)에 의해 회전되며 그 외주면에 다수의 캠홈(131,132)이 형성되는 캠(130)의 상면에 걸림핀(133)을 마련하여 덕트 내부의 개폐판을 회동시켜 흡기구를 개폐하도록 이루어진 전자렌지의 댐퍼개폐장치에 있어서, 상기 캠(130)의 일측에 설치되어 캠홈(131,132)에 의해 연동되는 마이크로스위치(140)와 전자렌지 조리제어용 마이컴의 제어를 받는 릴레이스위치(170)를 병렬로 상기 구동모터(150)에 결선하여 이루어진 전자렌지의 댐퍼 개폐제어회로를 제공함으로써, 구성을 간단히하고, 댐퍼 개폐의 신뢰성을 높일 수 있게 된다.In view of the above, the present invention provides a locking pin 133 on the upper surface of the cam 130, which is rotated by the drive motor 150 and is formed with a plurality of cam grooves 131 and 132 on the outer circumferential surface thereof to rotate the opening and closing plate inside the duct. In the microwave damper opening and closing device configured to open and close the intake port, the relay switch is provided on one side of the cam 130 and is controlled by the micro switch 140 and the microwave cooking control microcomputer interlocked by the cam grooves (131, 132) By providing the damper opening / closing control circuit of the microwave oven formed by connecting the 170 to the driving motor 150 in parallel, the configuration can be simplified, and the damper opening and closing reliability can be improved.
