Abstract

A microwave oven comprises a source of microwave energy for heating a food, a table for carrying the food, and an oven cavity with an uneven bottom wall for providing random reflection of the microwave energy wherein a distance between the uneven bottom wall of the oven cavity and the table is variable because of the uneven bottom to unify the intensity of the microwave energy throughout the oven cavity, whereby the food positioned on the table is exposed to uniform intensity of the microwave energy.
