Abstract

본 발명은 입력전압변화 및 주위온도저하에 관계없이 보온동작시 균일한 보온온도를 유지하는 전기보온밥솥에 관한 것으로써, 보온용히터의 용량을 가변시키도록 상기 보온용히터를 온/오프제어하는 트라이악과, 상기 트라이악의 게이트전류를 제한하는 전류제한저항과, 상기 보온용히터의 온도를 감지하여 상기 트라이악에 게이트신호를 인가하는 측면감온소자로 이루어진 것으로, 트라이악을 이용하여 보온용히터의 용량을 증대시켜 방출열량을 보완함으로써 입력전압변화 및 주위온도저하에 관계없이 균일한 보온온도를 유지하여 밥을 장시간 보온할 수 있을뿐만 아니라, 냄새발생을 제거하여 보온성능을 향상시킬 수 있다는 효과가 있다.The present invention relates to an electric heat cooker that maintains a uniform warming temperature during warming operation regardless of an input voltage change and an ambient temperature drop, the on / off control of the warming heater to vary the capacity of the warming heater. A triac, a current limiting resistor that limits the gate current of the triac, and a side temperature sensing element that senses the temperature of the thermal heater and applies a gate signal to the triac, and uses the triac of the thermal heater. By increasing the capacity and complementing the emitted heat, the rice can be kept warm for a long time by maintaining a uniform warming temperature regardless of the input voltage change and the ambient temperature drop, and can improve the warming performance by eliminating odors. have.
