Abstract

본 발명은 전자레인지의 자동요리 방법 및 장치에 관한 것으로, 종래에는 적외선센서의 감지면적이 턴테이블의 전체부분이므로 음식물만의 온도와는 상당한 차이를 보이고, 또한 연속동작시에는 전체적으로 턴테이블이 뜨거운 상태이므로 실제 음식물 온도와는 큰 차이를 보여 요리성능이 상당히 안좋은 단점이 있다. 따라서, 본 발명은 적외선센서의 센싱각도 및 면적이 턴테이블 위의 음식물이 놓여진 위치에 맞게 센싱각도가 조정되도록하고, 턴테이블의 회전에 따른 음식물의 이동에 맞추어서 센싱각도 및 감지면적이 따라 움직이면서 음식물의 온도를 계속적으로 집중 감지하도록 함으로써 요리성능을 향상시키도록 한다.The present invention relates to a method and apparatus for automatic cooking of a microwave oven, and in the related art, since the sensing area of the infrared sensor is a whole part of the turntable, it shows a considerable difference from the temperature of food alone, and in the continuous operation, the turntable is hot in general. It shows a big difference from the actual food temperature, so the cooking performance is very bad. Therefore, in the present invention, the sensing angle and area of the infrared sensor are adjusted so that the sensing angle is adjusted according to the position on which the food is placed on the turntable, and the temperature of the food is moved along with the sensing angle and the sensing area in accordance with the movement of the food according to the rotation of the turntable. Enhance your cooking performance by keeping them focused.
