Abstract

본 발명은 전자레인지등 대용량 가전기기에 사용되는 신규한 작동지연회로를 개시한다. 돌입전류에 의한 문제를 방지하기 위한 종래의 작동지연회로는 시멘트저항등 대용량 저항을 사용하게 되므로 원가가 높고, 크기가 대형이서 공간효율이나 조립성등 생산성을 악화시키는 문제가 있었다.The present invention discloses a novel operation delay circuit used in a large-capacity home appliance such as a microwave oven. The conventional operation delay circuit for preventing the problem caused by the inrush current has a problem of deteriorating productivity, such as high cost, large size, and space efficiency or assembly, because it uses a large capacity resistor such as cement resistance.

본 발명에서는 전원전압이 아니라 릴레이부의 제어신호를 지연시키도록 구성함으로써 소형 염가의 작동지연회로를 구현하였다.In the present invention, by implementing a delay of the control signal of the relay unit, not the power supply voltage, a low-cost operation delay circuit is realized.
