Abstract
An automatic cooking control system for a microwave oven which utilizes an initial operation process that shifts a temperature of inflow air stored in memories to other memories and repeatedly stores a present inflow air temperature in another memory until the present detected inflow air temperature is equal to the temperature stored in the memory. This initial process also determines a temperature variation in the inflow air and a temperature difference between the air flowing in and out. A temperature compensating portion is obtained from the temperature variation and difference, which is used to establish a temperature increment by dividing the temperature compensating portion into a predetermined temperature increment. The microwave oven then utilizes a first stage heating process until the temprature of the air flowing from a heating chamber is raised as much as the compensated temperature increment. When this condition is realized, a second stage heating process is carried out for the time of the first stage heating time multiplied by a predetermined value according to the kind of food being cooked.
