Abstract
The present invention discloses a salver for a microwave oven. The salver has an upper salver plate for carrying food. The plate base supports the upper salver plate and a heated air passage forms between the salver plate and a glass salver. The salver has at least a heated air staying wall formed on bottom side of the upper salver plate, which blocks the heated air to stay on bottom of the salver plate for a period of time. The wall is straight line or curve shape, preferentially is formed on center of the bottom of the salver plate. Because the existence of the air staying wall, the center of the bottom of the upper salver plate can effectively absorb a mass of heat such that the difference of heating speed between the top and the bottom of the food on the salver is reduced.
