Microwave oven

摘要

The present invention relates to a microwave oven including an oven door and a heating chamber with a back wall, and the oven door is installed in the front of the heating chamber. There are more than one protrusion disposed on the back wall, and each of the protrusions has more than three reflecting surfaces and protrudes toward an inside of the heating chamber. The back wall of the heating chamber in the microwave oven has the structure of a plurality of reflecting surfaces, which makes the microwave emitted by a magnetron reach every position of the heating chamber by reflection of the multiple reflecting surfaces, thereby the microwave distributes more evenly and consistently, thus the food may be heated more rapidly and uniformly.
