Microwave oven at home.

I always think about having a machine that can put the dishes and rice in it, press the button, and when the time comes, it will automatically stop, the dishes and rice are fragrant, and they are delicious, how good is that!

Unexpectedly, today my parents bought back a machine of my dreams. As soon as I moved home, I was like a stimulant, and I was so happy that I wanted to see what it was like. As soon as my mother opened the box, I saw the magic microwave.

I looked closely, and it was cuboid with a black shell. In front of the microwave oven is a door with transparent glass that allows you to see inside. There is also an exhaust vent above to remove the hot air generated by heating.

On the right side of the door there are a number of buttons: the fire button, the clock button, the barbecue button, the weight adjustment button, the time button, the start button, and the stop and cancel button. These keys all serve different purposes.

The microwave has a rotating glass tray inside the oven for heated food.

If you want to heat up the rice or cook the vegetables, put the rice or vegetables into the special bowl of the microwave oven, put it in the microwave oven, twist the time button to a certain time, and then press the start button to start running. When the time comes, it will automatically turn off and the steaming meal will be ready.

If you want to barbecue, put things on the barbecue grill, put them in the microwave, and the barbecue is much slower than hot rice, about ten minutes, and you also twist the time button to twelve or thirteen, then press the barbecue button, and finally press start. When it is baked for two or three minutes, the aroma comes out of the exhaust vent, making people's mouths water. Not to mention the barbecue, it's a veritable delicacy!

If you know the weight of the food, you can press the weight adjustment button, and it can set the time by itself, which is more convenient.

If you want to do it quickly, you can also add firepower!
