Abstract: An automatic cooking control system for a microwave oven having a turntable utilizes an initial operation process which makes the air temperature of a heating chamber by uniformed only operating a fan. The automatic cooking control system further utilizes first stage heating operation process which actuates a magnetron after the initial operation process. The first stage process detects, an outflow air temperature, stores it as a present temperature, and obtains an arithmetical mean of the present temperature and a previous temperature detected prior to a half rotational period of the turntable. The first stage heating operation process is carried out until the arithmetical mean is raised as much as a predetermined value established according to the kind of food being cooked. The system also utilizes a second stage heating operation process which is carried out for a time period that is obtained by multiplying the first stage heating time by a predetermined value established by the kind of food being cooked.

Abstract: An automatic cooking control system for a microwave oven utilizes an initial operation process which determines an initial operation process which determines a temperature increment compensating portion from a temperature variation and a temperature difference. The system also utilizes a first stage heating process which executes heating operations until the air temperature of the air flowing out of a heating chamber is raised as much as the compensated temperature increment. A second stage heating process is also utilized to execute a heating operation for a period of time that is equal to the first stage heating period of time multiplied by a predetermined value. The predetermined value is set according to the kind of food being cooked. Even if one is cooking a new food immediately after another food has been cooked, the food can be automatically cooked correctly and optimally.
