Abstract
A microwave oven includes a cooking chamber, a tray disposed in the cooking chamber upon which food can be placed, and a magnetron for supplying high frequency waves to the cooking chamber. The microwave oven has a food-thawing mode and a food-cooking mode. In the thawing mode, the oven is capable of bringing food to different states of thawing in response to the selection of a specific food-thawing key. In the food-cooking mode, various cooking levels can be selected.
