After the May Day, the weather in the south began to heat up. The best way to cool off in the summer is not to go out in the air-conditioned room. Opening the refrigerator and taking a bottle of summer drink seems to be easy to satisfy. Especially for fans who are going to stay up late to watch the World Cup, the cold beer in the refrigerator is definitely the best match for watching the ball.
However, when you open the refrigerator, you find that the refrigerator is covered with frost. This will not only reduce the cooling efficiency of the refrigerator, but also increase the burden of electricity. It will also cause trouble for you to put things and take things. Defrost is really a headache. Handcuffs and knives are used to cut the axe. In fact, the defrosting is not as difficult as everyone imagined. In this issue, we will come together to see what kind of refrigerator. A good way to defrosting.
Why does the refrigerator get frosty?
Water vapor meets condensation, which is the principle of physics. How does the water vapor in the refrigerator come from? Of course it is in the air. When the refrigerator is used, the air inside and outside the ice is freely exchanged, and the humid air in the room enters the refrigerator to form a frost. Especially in summer, the indoor temperature is higher, the humidity is also larger, the refrigerator is used more frequently, and the refrigerator freezes faster.
In addition, the food we store in the refrigerator, vegetables and fruits contain more water, there is no completely cool food in the refrigerator, the water is easy to evaporate and condense into frost.
Should the cream in the refrigerator be removed?
Of course you have to clear it. Some friends have a thick frost in the frozen layer of the refrigerator at home. Regardless of the waste of storage space, thick frost will also hinder the heat exchange on the surface of the evaporator, resulting in no refrigeration effect of the refrigerator. it is good. Then you will find that your meter is screaming in the summer, and it is very energy-saving and environmentally friendly.
If the thickness of the frost in the freezer reaches 5cmm, you should take out the tool to defrost. Look at the frequency of your use, storage habits and the performance of the refrigerator. Generally, it will be defrosted once every three or four months. If you don't care, wait until the frost gets thicker and thicker, and the defrosting becomes very troublesome.
Is there any way to skillfully defrost?
1. Make adequate preparations before defrosting. Turn off the power, then empty the refrigerator and take out the various trays, drawers, and shelves in the refrigerator. Some refrigerators have drains on the bottom, find the outlet of the drain, and don't know where to come from when you spill water. Of course, it is best to pad some water-absorbing things around the refrigerator, such as newspapers and rags.
2. Open the refrigerator door and wait for the melt. This is the laziest and the most trouble-free and pollution-free method, but the time may be longer, and the dissolution rate may be faster in summer. In winter, it is estimated to wait a day or two.
3. The electric fan blows straight. Directly set up an electric fan and blow it in the refrigerator. The fan blows hot air into the refrigerator, takes away the cold air, and takes away the frosty water vapor, directly letting the frost sublimate. This is also very fast, and it will be cleaned in about half a day.
4. Put a few bowls of hot water in the refrigerator. Although this method works well, I personally feel more troublesome. And the efficiency can be slower than the electric fan blowing. Maybe you have to change a few bowls of hot water when the water is cool.
5, the hair dryer blows. If you are really idle, you can also blow the ice to the icing with a hair dryer. It is best to choose a non-constant electric fan so that the temperature is higher and it is easier to melt. However, I have to pause for a while, otherwise I will be careful when the temperature of the hair dryer is too high.
6, wipe the cloth. This is probably the most laborious method of defrost. I used to do it for the first time. I used a hot towel to wipe it hard. But the ice was too thick. It didn't work for a long time.
7, fruit knife scraping. This is the most violent method. Of course, there are certain risks. The insulation layer of the refrigerator liner will be scratched. If the scratches are deep, it will affect the insulation effect. However, there are also plastic shovel that can be used, but not as violent as iron.
Of course, you can also use a combination of 7 methods, such as putting a few bowls of hot water in the refrigerator, and turning on the electric fan to blow the refrigerator. After a few hours, the ice is about to melt, and you can quickly use a shovel or a knife. The whole piece of frost is peeled off. Finally, some of the remaining ice cubes are rubbed with a hot towel.
Remember to clean the water on the refrigerator after the defrosting, and use it to ensure that it is not so fast and frosted.
How to make defrosting easy?
The method of defrosting mentioned above is a plan to make up for it. There is also a small trick to use before frosting. When the next defrosting, it will save time and effort.
On the inner wall of the frozen layer of the refrigerator, evenly spread a layer of cooking oil. Then put on a layer of plastic wrap to ensure that the refrigerator will not be frosted for a period of time, and after frosting, it will be easy to push, and the frost will fall off happily.
Frost-free refrigerator is king
The above said that the method of defrosting is not as straightforward as buying a frost-free refrigerator directly. A frosty refrigerator is a direct-cooling refrigerator, and a frost-free refrigerator refers to a refrigerator that is air-cooled or wind-cooled. Nowadays, many refrigerators are air-cooled or air-cooled and cold-cooled. You can pay attention to it when you buy it.
Direct cooling of the refrigerator through the cooling tube, the structure is simple, the price is low, because the air is not convective, the temperature is not uniform, the taste in the refrigerator is also very heavy.
Air cooling is the way to cool the wind, it will also frost, but the frost is in the air duct, but this type of refrigerator has automatic defrosting function, even using the frost in the air duct to exchange heat for the refrigerator. . Air cooling is also divided into single cycle and multiple cycles. There is only one wind blowing in a single cycle, and multiple cycles can blow the refrigerator compartment. Multi-cycle temperature control is more accurate, and refrigeration is fast and efficient.
However, there is also a disadvantage in air cooling that is easy to air dry food. For example, fruits and vegetables are easily dried, but high-end refrigerators have moisturizing functions. Secondly, there is the possibility of odor, but the high-end refrigerator has a compartment. In the end, it is to see how much you are willing to spend to buy a refrigerator.
Summary: In the hot summer, come to a glass of iced coke and don't mention more cool. But when you open the refrigerator door and find a bunch of condensed frost, the mood is not so bright. So the defrosting skills have been learned? If you don't have money, come to a multi-cycle air-cooled, moisturizing and deodorizing refrigerator, then you can do everything.
