The characteristic of flat-plate microwave oven is that there is no turntable inside, but a technology called "flat-plate waveguide" is adopted. The microwave is dispersed to all corners of the microwave oven through a metal plate, so that food is evenly radiated by the microwave. The advantages of this design are saving space, improving the capacity of microwave oven, no turntable, and more convenient cleaning.

The rotary microwave oven is characterized by a rotatable disk inside, and food is placed on the disk. When the microwave oven works, the disc will automatically rotate, so that the food is evenly radiated by the microwave. The disadvantage is that the disk occupies a certain space, which limits the capacity of the microwave oven, and the disk needs to be cleaned regularly, otherwise dirt and bacteria will accumulate, so the flat microwave oven is better.

Matters needing attention in the use of microwave oven

The working principle of microwave oven is to use the energy emitted by electromagnetic waves to heat food, and electromagnetic waves will react with metals, and there is no way to absorb or conduct them at all, so it is impossible to heat food in metal utensils. If the whole bag of food is attached with metal clips or strips, it is best to take out the metal objects and put them in the microwave oven.

The local high temperature generated by microwave heating produces steam, that is, high pressure. Once a closed container is used, an explosion may occur. If you use a container with air holes, even if it is a shelled food such as eggs, you should first pierce the shell with chopsticks.
