Abstract

본 발명은 전기보온밥솥의 보온공정 제어기술에 관한 것으로서, 특히 보온시 밥솥내부의 밥량의 차에 따라 보온히터의 출력이 적절하게 제어되도록 함으로서, 보온성능이 향상되도록 한 전기보온밥솥의 보온공정 제어방법에 관한 것으로, 통상의 취사완료후 보온공정이 진행되는 공지의 전기보온밥솥에 있어서, 상기한 취사완료후 취사완료온도인 127℃에서 저하되어 100℃까지 도달한 시점까지의 시간(A)과, 이후 100℃에서 저하되어 80℃까지 도달한 시점까지의 시간(B)을 체크하되, 상기한 시간(A)(B)을 평균값으로 취한 시간을 기준시간(C)으로 세트하는 제1단계와; 상기 제1단계에서 구한 기준시간(C)과 미리 설정한 시간을 비교하는 제2단계와; 제2단계의 비교결과에서 기준시간이 설정시간보다 큰 경우에는 밥량이 많은 상태로 판단하여 트라이액출력을 감소제어하며, 기준시간이 설정시간보다 작은 경우에는 밥량이 적은 상태로 판단하여 트라이액출력을 증가제어하는 제3단계로 구비하여 밥량의 차에 따라 트라이액출력이 적절하게 제어도록 한 특징이 있다.The present invention relates to a thermal insulation process control technology of an electric thermal rice cooker, in particular, to ensure that the output of the warming heater is appropriately controlled according to the difference in the amount of rice inside the rice cooker when warming, the thermal insulation process control of the electric thermal cooker to improve the thermal insulation performance The method relates to a well-known electric heating rice cooker in which a warming process is performed after completion of normal cooking, wherein the time (A) from the cooking completion temperature until the temperature is lowered from 127 ° C to 100 ° C and After that, the first step of checking the time (B) until the time point is lowered from 100 ℃ to reach 80 ℃, and the time (A) (B) is taken as the average value and the reference step (C) and ; A second step of comparing the reference time (C) obtained in the first step with a preset time; In the comparison result of the second step, when the reference time is greater than the set time, the amount of rice is judged to be large and the triac output is reduced. If the reference time is smaller than the set time, the triac output is judged to be low. The third step of increasing the control is characterized in that the triac output is properly controlled according to the difference in the amount of rice.

Claims

In a well-known electric heating rice cooker in which the warming step is performed after the normal cooking, the time (A) until the temperature is lowered from 127 ° C., which is the cooking temperature after completion of cooking, to 100 ° C., and then at 100 ° C. A first step of checking a time (B) until the point at which it is lowered to reach 80 ° C., wherein the time (A) (B) is taken as an average value as a reference time (C); A second step of comparing the reference time (C) obtained in the first step with a preset time; In the comparison result of the second step, when the reference time is greater than the set time, the amount of rice is judged to be large and the triac output is reduced. If the reference time is smaller than the set time, the triac output is judged to be low. And a third step of controlling the increase, so that the triac output is properly controlled according to the difference in the amount of rice.
