Abstract

본 발명은 전자레인지의 산 농도(PH) 감지장치에 관한 것으로, 종래에는 산 농도의 감지없이 적정온도 대역에서 음식물의 숙성이나 발효를 행함으로써 정확한 요리를 행할 수 없었다.The present invention relates to an acid concentration (PH) detection device of a microwave oven, and in the related art, accurate cooking could not be performed by aging or fermenting food in an appropriate temperature range without detecting acid concentration.

따라서 종래의 문제점을 해결하기 위하여본 발명은 1SFET(Ion Sensitive Field Effect Transistor)구조를 갖는 산 농도(PH) 센서를 가열할 음식물에 꽂아 산 농도를 직접적으로 감지하면서 온도센서로서 전자레인지의 가열실내 온도를 적절하게 조절함으로써 요리성능의 향상과 자동요리를 꾀할 수 있도록 한 효과가 있다.Therefore, in order to solve the conventional problems, the present invention is to insert the acid concentration (PH) sensor having a 1SFET (Ion Sensitive Field Effect Transistor) structure into the food to be heated to directly detect the acid concentration while the temperature in the heating chamber of the microwave oven as a temperature sensor By properly adjusting the effect of improving the cooking performance and automatic cooking is possible.
