Abstract: An automatic cooking control method for a microwave oven using data pattern of food, including the steps of: (a) collecting data outputted from a data detecting section for a predetermined time; (b) comparing the collected data with at least one prestored data pattern; and (c) selecting the data pattern among the prestored data pattern that is most similar with the collected data, and performing a cooking operation corresponding to the selected data pattern. When the data collected for the predetermined time corresponds to a no-load pattern, the microwave oven stops the cooking operation. Without separate external data input about weight or physical status of the food in the cooking chamber, the microwave oven automatically selects the most proper cooking process for the food in the cooking chamber by comparing the data about the food in the cooking chamber with the data patterns of the various foods prestored in the microwave oven.
