These four kinds of household appliances can heat food, and the heating principle is divided into microwave oven and other two kinds. The heating principle of microwave oven sounds the biggest: when working, it emits high-frequency electromagnetic waves (microwave heating) to the internal structure, and the vibration frequency of microwave heating is relatively high, which will cause moisture impact. When water vibrates rapidly, it becomes hot, thus heating food.
Compared with the other three kinds of household appliances, microwave oven has the fastest heating speed and very simple operation, so it has the highest coverage. The main disadvantage is that water needs to volatilize quickly during rapid vibration, resulting in insufficient water in food. Heating steamed bread and toast for a long time will make you feel stiff-in fact, it is because the water in the food has escaped. The same is true of hot leftovers. After being heated in a microwave oven, the taste of leftovers usually changes greatly.
When people use the microwave oven, it is usually fast. If you often need to heat leftovers, steamed bread and rice, you can buy a microwave oven. Some microwave ovens are said to cook. I tried it and it was hard to swallow. Some products are independent microwave ovens, and more are microwave ovens and microwave oven products. The structure of the microwave oven is relatively simple: a lamp tube with a relatively high calorific value is installed in the microwave oven, and food is heated by the lighting effect.
As mentioned earlier, the average speed of microwave heating is the fastest. Therefore, although the optical wave oven is the same as the microwave oven in appearance design, it is even integrated with the microwave oven, but the heating speed is much slower. It may take another 30 seconds for a dish to be heated by microwave, and it takes 3 minutes for microwave heating. Its characteristic is that the heating method is very traditional, which can keep the original flavor of leftovers. If you are not in a hurry, of course you can wait a little longer. In terms of choice, Qijia's indoor sister suggested buying microwave heating and microwave products directly. The two functions are basically the same, and they can complement each other.
The principles of electric oven, pulsator oven and electric oven are mostly the same. They all use heating pipes to radiate solar energy and bake food. The difference is that the output power of electric oven is dozens of times that of microwave oven, so it emits more heat. However, the indoor space of electric oven is usually very large, so it must be heated when used, and the light wave oven can be used directly. Therefore, the microwave oven is more convenient and is generally used to heat leftovers. Electric ovens can provide higher, wider and more uniform calorific value, so they are used for cooking.
