Abstract

본 발명은 전자레인지의 조리물 중량을 감지하는 신규한 중량센서를 개시한다.The present invention discloses a novel weight sensor for sensing the weight of food in a microwave oven.

종래의 정전용량방식 중량센서는 대향되는 전극간에 평행이동이 어렵고, 조리물등으로부터의 이물의 유입에 의해 유전율이 변화되어 정확한 중량의 감지가 불가능하고 측정된 중량의 신뢰성이 낮아 전자레인지의 적절한 제어가 어려웠다.Conventional capacitive weight sensors are difficult to move in parallel between opposing electrodes, the dielectric constant is changed by the inflow of foreign objects from food, etc., it is impossible to accurately detect the weight and the reliability of the measured weight is low, the proper control of the microwave oven It was difficult.

본 발명에서는 절연판에 전극패턴을 형성하여 이를 봉합하고, 별도의 프루브를 구비하여 작은 면적으로 회전축의 압력을 전달하도록 함으로써 이러한 문제를 해결하였다.(제3도)In the present invention, this problem was solved by forming an electrode pattern on the insulating plate and sealing it, and having a separate probe to transmit the pressure of the rotating shaft to a small area.
