ABSTRACT:
This invention relates to a method for automatic control of a microwave oven which can make precise cooking control available by classifying the cooking control into cases when cooking is completed below the boiling point of water, such as thawing or warming up, and cases when cooking is completed above the boiling point of water. For types of cooking which are complete without water boiling, the invention sets the initial cooking time period by determining the time it takes for the output voltage of a temperature detection sensor to reach a rise starting point. For types of cooking which include water boiling, the invention sets the initial cooking time period by determining the time it takes for the output voltage of the temperature detection sensor to reach a maximum rise point. The invention then sets an additional time period equivalent to the initial time period multiplied by a cooking constant corresponding to the type of cooking that is desired.
