Abstract

본 발명은 전자렌지 음식물 중량 감지방법에 관한것으로 종래에는 요리하고자 하는 음식물을 전자레인지 속에 넣으면 그 음식물이 글래스 트레이의 중앙에, 놓이지 않고 한쪽으로 편심되게 놓일경우와 정상적인 경우 모두 동일하게 무게를 감지하여 편심될 경우 실제 무계보다 무겁게 감지하는등 정확하게 중량을 감지할수 없어 전자레인지의 성능을 저하시키는 문제점이 있었다.The present invention relates to a microwave food weight detection method in the prior art when the food to be cooked in the microwave when the food is placed in the center of the glass tray, eccentrically to one side and not placed in the normal case to sense the weight In case of eccentricity, there is a problem in that the performance of the microwave is deteriorated because the weight cannot be accurately detected, such as the weight of the body.

본 발명은 상기와 같은 문제점을 감안하여 글래스 트레이위에 음식물이 놓이면 정상적인 상태와 편심상태로 판단하여 편심상태이면 특정식으로 보상하여 편심 상태에서도 음식물의 중량을 정확하게 판단하여 전자레인지의 성능을 향상하는 효과가 있다.The present invention is to determine the normal state and the eccentric state when food is placed on the glass tray in view of the above problems to compensate in a eccentric state to determine the weight of food accurately in the eccentric state to improve the performance of the microwave oven There is.
