Abstract:
1. A control method for cooking food placed on a turntable in a microwave oven, comprising: detecting a plurality of sensing values generated according to a weight of food to be cooked during the rotation of the turntable; detecting a food position by comparing the detected sensing values; and controlling the microwave output based on the detected food position, wherein the food position is estimated by obtaining a maximal value and a minimal value among the detected sensing values and by substituting a difference between the maximal value and the minimal value into a weight formula, the maximal value is a maximal voltage value obtained by subtracting an initial voltage value from a greatest value among the detected sensing values and the minimal value is a minimal voltage value obtained by subtracting the initial voltage value from a lowest value among the detected sensing values, wherein the weight formula varies according to the weight of the food.
