Abstract
본 발명은 보온시 전기보온밥솥 내부의 밥량을 체크하여 온도 제어를 달리하므로써 최적의 보온 상태를 유지시키는 밥량에 의한 보온온도 유지방법에 관한 것으로써, 종래의 보온 밥솥의 보온온도 유지방법에 있어서, 75℃의 보온 온도를 맞추기 위해 밥솥의 밥량에 관계없이 일정하게 구동되어 밥솥 내부에 밥량이 적을 때는 밥이 굳거나, 양이 많을 때는 보온이 잘 되지 않고 색이 변하며 냄새가 나는 문제점이 발생하게 되었다.The present invention relates to a method of maintaining the warming temperature by the amount of rice to maintain the optimal warming state by varying the temperature control by checking the amount of rice inside the electric warming cooker at the time of warming, in the warming temperature maintaining method of the conventional warming cooker, In order to keep the temperature at 75 ℃, the rice cooker is constantly driven, regardless of the amount of rice cooked. .
따라서 본 발명은 위에서 상술한 바와 같은 종래 기술의 문제점을 해소하기 위하여 전기보온밥솥에 있어서, 취사가 완료되는 온도(127℃)에서 보온 온도(75℃)까지 떨어지는 온도 분포곡선의 기울기를 연산하여 내부 밥량을 감지하고 보온 온도를 제어하므로써 최적의 보온 상태를 유지하여 밥이 굳거나 색이 변하고 냄새가 나는 것을 방지하기 위하여, 전기보온밥솥의 보온온도유지회로에 있어서, 상기 밥솥의 내부온도를 감지하는 보온 온도센서 입력부와, 보온온도센서입력부의 입력을 받아 그 값을 연산 및 처리하는 마이컴과, 상기 마이컴의 연산결과에 의해 설정된 값으로 구동되는 보온히터 구동부와, 보온 히터로 구성되고, 상기 보온 히터 구동부는 저항과, 트리이악과, 트랜지스터로 구성함과 동시에, 취사가 완료된 후 밥솥 내부의 온도 기울기를 검사하고, 상기 검사 값을 미리 마이컴에 저장되어 있는 값과 연산하여 밥량을 판단하고, 상기 결과에 의해 보온시 트라이악을 조정하도록 제어하게 한 것을 특징으로 한다.Therefore, the present invention is to calculate the slope of the temperature distribution curve falling from the temperature (127 ℃) to the warming temperature (75 ℃) in the electric insulation rice cooker to solve the problems of the prior art as described above in the interior In order to prevent the rice from hardening, changing color, or smelling by maintaining an optimal warming state by sensing the amount of rice and controlling the warming temperature, in the warming temperature maintaining circuit of the electric warming rice cooker, The thermal insulation heater is composed of a temperature sensor input unit, a microcomputer that receives the input of the thermal temperature sensor input unit and calculates and processes its value, a thermal heater driver driven by a value set by the calculation result of the microcomputer, and a thermal heater. The drive unit consists of a resistor, a triac, and a transistor, and at the same time, the temperature gradient inside the cooker after cooking is completed. Check, and the check value, it characterized in that the pre-computes the value stored in the microcomputer determines the bapryang, controlled so as to adjust the triac during keeping warm by the result.
