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. This system can automatically cook food with the correct heating time even though the outflow air temperature detected by a temperature sensor oscillates due to the rotation of the turntable.
