Abstract

본 발명은 전자레인지의 중량감지장치에 관한 것으로, 일반적인 전자레인지는 음식물의 중량을 용량성센서, 압전소자, 차동트랜스를 이용하여 감지하게 되므로써 원가가 상승되는 문제점이 있었다.The present invention relates to a weight detection apparatus for a microwave oven, and a general microwave oven has a problem in that the cost is increased by detecting the weight of food using a capacitive sensor, a piezoelectric element, and a differential transformer.

이를 보완하기 위한 본 발명은 가열실의 턴테이블을 회전시키고 음식물의 중량변화에 따른 토오크변화를 전류의 변화로 출력하는 턴테이블모터와, 그 턴테이블모터에서 발생되는 전류의 변화로 음식물의 중량을 측정하여 마이콤에 입력하는 중량감지부로 구성하여 턴테이블 구동과 중량감지의 역할을 동시에 수행하게 함으로써 원가절감 및 시스템이 간소해지는 효과가 있는 것이다.The present invention to compensate for this is a turntable motor for rotating the turntable of the heating chamber and outputs a torque change in accordance with the change in weight of the food as a change in current, and by measuring the weight of the food by the change in the current generated from the turntable motor to micom Composed of a weight sensing unit to be input to the turntable driving and weight sensing to perform the role of at the same time has the effect of reducing costs and simplifying the system.
