After the May 1st, the weather in the south began to heat up. The best way to relieve heat in the summer and summer is to stay in the air-conditioned room without going outside. Opening the refrigerator and taking a bottle of hot summer drinks seems easy to satisfy. Especially for those who are about to stay up late For the World Cup fans, the cold beer in the refrigerator is definitely the best match for watching the game.
However, when you open the refrigerator, you find that the refrigerator is full of frost, which not only reduces the cooling efficiency of the refrigerator, but also increases the power bill. It will also cause trouble for you to put things and take things. Defrosting is really a headache. With a handkerchief, with a knife, it's worse to cut it with an axe. Actually, defrosting is not as difficult as everyone thinks. In this issue, let's take a look at some of the best ways to defrost the refrigerator.
Why is the refrigerator frosted?
Water vapor condensation, this is the understanding of physics everyone knows. That the refrigerator's water vapor come from? Of course, in the air. When using the refrigerator, the ice eliminates the exchange of internal and external gases, the indoor moist air into the refrigerator case of condensation into the frost. Especially in summer, the indoor temperature is high, the humidity is relatively large, the refrigerator is used more frequently, and the refrigerator freezes faster.
In addition, we store food in the refrigerator, vegetables and fruits contain more water, and there is not completely cool food in the refrigerator, the water easily evaporates, condensed into a frost.
Do you want to clear the frost in the refrigerator?
Of course, it must be removed. Some friends have a thick layer of frost on the refrigerator's freezer floor. Regardless of this, this will not only waste a lot of storage space, the thick frost will also hinder the heat exchange on the evaporator surface, leading to the refrigerator. The cooling effect is not good. Then you will find that your own electricity meter will whisper as soon as it is in summer. It is very energy-saving and environmentally friendly.
If the frost thickness in the freezer reaches 5cmm, you should take out the tool to defrost. Look at your frequency of use, storage habits and performance of the refrigerator. Normally defrosting once in three or four months. Regardless of this, defrosting can become very troublesome as the cream builds up.
Is there any clever defrost?
1. Make full 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 at the bottom to find outlets for the drains. It's best not to know where the water came from. It's best to add some absorbent material around the refrigerator, such as newspapers and rags.
2. Open the refrigerator door and wait for it to melt. This is the laziest and most convenient way to save pollution. It may only be a long time. The speed of dissolution in summer may be faster. In winter, it is estimated that it will take a day or two.
3. The electric fan blows directly. Directly holds an electric fan and blows it into the refrigerator. The fan blows the hot air into the refrigerator, takes away the cold air, and also takes away the vapor of the frost, which directly sublimates the frost. It is also very fast. It will take about half a day to clean.
4, put a few bowls of hot water in the refrigerator. Although this method is also useful, but I personally feel more troublesome. And the efficiency is willing to blow even slower than the electric fan. May have to wait for the hot water to have a few bowls of hot water.
5, hair dryer blowing. If you are really busy, you can also hold the hair dryer to blow it against the ice. It is better to choose a non-constant temperature fan, so that the temperature is higher and it is easier to melt. For a moment, be careful that the hair dryer is overheated for a long time.
6, rag wipe. This is probably the most laborious method of defrosting, and the first time I was doing this, with a hot towel to wipe hard, but unfortunately the ice is too thick, wipe for a long time no effect.
7, fruit knife scraping. This is the most violent method, of course, there is a certain risk, the insulation of the refrigerator liner will be scraped, if the scratches are relatively deep, it will affect the insulation effect. But there are plastic shovels can be Use, but no iron is so violent.
Of course, you can use 7 methods in combination, for example, put a few bowls of hot water in the refrigerator, and turn on the fan to blow to the refrigerator. After a few hours, the ice will melt, and you can quickly put it with a shovel or a knife. The whole piece of frost is peeled off. The last pieces of ice are wiped with a hot towel.
Remember to clean the refrigerator after defrosting, and use it after power on. Make sure that it is not so fast and frosty.
How to make defrosting easier?
The defrosting methods mentioned above are all ways of remedying the situation. There is also a small trick to use before frosting. When the next defrost is done, it will save time and effort.
On the inner wall of the refrigerator's freezing layer, evenly apply a layer of cooking oil. Then, apply a layer of plastic wrap to ensure that the refrigerator is not frosted for a period of time. After frosting, it can be easily pushed and the frost can be enjoyed. Down.
Frost-free refrigerator is king
The above method of defrosting is not as straightforward as buying a frost-free refrigerator. A frost-free refrigerator is a direct-freezer, and a frost-free refrigerator is a combination of air-cooled or air-cooled refrigerators. Many refrigerators are either air-cooled or air-cooled refrigerators. Take care when buying.
When the refrigerator is directly cooled, it is directly cooled by a cooling pipe. The structure is simple and the price is low. Because the air does not convective, the temperature is not uniform, and the taste in the refrigerator is also very heavy.
Air cooling is cooling by blowing cold air. It also frosts, but frost is in the air duct. However, this type of refrigerator has automatic defrosting function, and even uses the frost in the duct to exchange heat for the refrigerator. Air-cooling is also divided into single-cycle and multi-cycle. There is only one wind in a single cycle, and multiple cycles can be used to partition the cold room. Multi-cycle temperature control is more accurate, and the cooling efficiency is high.
However, air-cooling also has a disadvantage in that it is easy to dry foods. For example, fruits and vegetables are easily dried, but mid-to-high-end refrigerators have moisturizing functions. Next, there is the possibility of odor, but there is a compartment in the high-end refrigerator storage area. Look at how much money you are willing to spend on what grade refrigerator.
Summary: In the hot summer days, I would like to have a cold and cozy Coke. However, when you open the refrigerator door and find a bunch of condensed cream, the mood is not so bright. So did the defrosting skills learn it? If not bad money, come A multi-circulation air-cooled refrigerator with moisturizing, deodorizing and freezer can also be a good thing.
