Abstract
Description
Claims (1)
- 소정의 등가용량을 가지는 히터를 SCR로 트리거시켜 이 히터에 전원전압의 공급을 제어함으로써 전기요의 온도를 제어하는 회로에 있어서, 100V/220V의 전원 전압의 크기에 관계없이 일정전류를 공급하는 정전류 공급회로부(1)와, 상기 정전류 공급회로부(1)의 일정전류에 의하여 충전되는 소정의 등가용량을 가지는 전기요의 히터부(2)와, 상기 히터부(2)의 등가용량이 소정전압까지 충전되어 있는 지의 여부를 검출하는 충전 전압검출부(3)와, 상기의 정전류 공급회로부(1)에 소정전압을 인가한 후, 충전 전압 검출부(3)의 출력이 소정 레벨로 변환되는 시간에 근거하여 전기요의 온도를 검출하고, 소정 설정온도로 전기요의 온도를 제어하도록 제어신호를 출력하는 마이크로프로세서(5)와, 상기 마이크로프로세서(5)의 제어신호에 대응하여 상기 전기요의 히터부(2)의 입력전원을 스위칭하는 히터부의 전원전바 스위칭부(4)를 구비하여 100V/220V 전원전압에 관계없이 일정하게 전기요의 온도를 제어함을 특징으로 하는 전기요의 온도제어회로.
