Microwave ovens use high-temperature microwaves to heat food. They can also simply bake food and can also sterilize at high temperatures. Main functions, examples:

1. Heating food. Usually the food is cold after it is cooked, but you can always use the microwave to heat it up when you want to eat it. It is more convenient to heat the food directly in the microwave without putting it in the pot, and it only takes a few minutes.

2. Barbecue function. You can make simple barbecues, such as roasted sweet potatoes, grilled chicken wings, etc.

3. Heating drinks. If milk, coffee and other beverages are too cold, if you like hot drinks, you can heat them in the microwave. A cup will take 1-2 minutes.

4. Sterilization function. Rags and wooden chopsticks can easily breed bacteria over time, so they can be soaked and placed in the microwave to heat and sterilize.

5. Rice cooking function. For example, if the rice cooker suddenly breaks down, you can use a microwave oven instead of cooking rice temporarily, and use a microwave heat-resistant plastic rice cooker to wash the rice and cook it.

Some smart microwave ovens have more functions. They will come with instructions and menus when you buy them. You can also use the microwave oven to make some simple dishes. There are some specific functions that need to be practiced by yourself.
