Automatic cooking apparatus and method for microwave oven

An automatic cooking method for a microwave oven comprising the steps of:

• driving a magnetron and a turntable upon an input of an automatic cooking start key during a predetermined time, and continuously measuring a weight of a food to be cooked and a microwave energy level not absorbed into the food;
• calculating an average value of said microwave energy level and an average value of said weight of the food;
• calculating a relative dielectric constant and a dielectric factor of the food on the basis of said average microwave energy level and said average weight;
• identifying the food to be cooked in accordance with said relative dielectric constant and said dielectric factor, and obtaining a cooking time corresponding to the food;
• and
• cooking said food for said cooking time.

An automatic cooking apparatus for a microwave oven, comprising:

• means for radiating microwave energy through a waveguide into a heating chamber;
• a turntable means disposed on a bottom of the heating chamber, for rotating a food to be cooked within the heating chamber;
• means for sensing a weight of food placed on the turntable for a predetermined time;
• means for sensing a microwave energy level not absorbed into the food within said heating chamber for said predetermined time;
• control means for calculating an average weight of the food and an average microwave energy level with respect to said predetermined time, calculating a relative dielectric constant and a dielectric factor of the food in accordance with said average weight and said average microwave energy level, identifying the food in accordance with said relative dielectric constant and said dielectric factor of the food, obtaining a cooking time corresponding to said identified food, and controlling cooking of the food for said cooking time.
