ABSTRACT:
A microwave oven, and method of controlling the same, stores a weight of food in an external memory of the microwave oven through a simple manipulation of pressing a hold key, and applies the stored weight of the food for calculation of a cooking time. The microwave oven of the present invention may perform cooking by calculating a cooking time based on the weight of the food temporarily stored in an internal memory even if a setting operation using the hold key is not performed. Further, the present invention is advantageous in that it calibrates a zero point to calculate the cooking time, increasing a cooking performance. The microwave oven performs initialization by deleting the stored weight of the food if a cooking start key is not pressed within a set time after the weight of food is measured, thus preventing a malfunction of the microwave oven.
