What if the refrigerator freezes?

With the arrival of summer, many consumers find that there will be icing in the refrigerator freezer at home, and this phenomenon will also occur in high temperature weather as high as 35 degrees. Why?

Relevant experts explained that the phenomenon of freezing in the refrigerator freezer belongs to the defrosting process. In summer, the ambient temperature is very high, but the temperature in the refrigerator is very low. When people open the refrigerator frequently, there will be obvious temperature difference inside and outside the refrigerator. The water vapor in the environment suddenly gets cold in the freezer of the refrigerator and turns into frost. If not handled in time, a thick layer of ice will form over time.

The freezer of the refrigerator often freezes, which consumes a lot of electricity and takes up a lot of freezer space. If you want to keep the refrigerator from freezing, you must first melt the ice in the freezer, and then coat the inner wall of the freezer with cooking oil, so that the refrigerator will not freeze.

As we all know, the freezer of the refrigerator has the function of fresh-keeping and refrigeration, and the freezer will freeze, but have you ever seen the phenomenon of freezer freezing?

Some time ago, when I was cooking dinner, I went to the refrigerator to get eggs. No, all the eggs are frozen and cracked. Let me see if other foods are frozen, too Everything is normal in the freezer, and all the food is well frozen. Why does the freezer freeze? Is the refrigerator broken? Or what other reasons?

I immediately unplugged the power socket of the refrigerator and left the door of the freezer open. When the ice in the freezer melted naturally, I checked the position of the food, and there seemed to be nothing unusual. So, I will wait until the ice melts, and now I don't see any problem. Hey, it's so hard to wait today. Finally, at night, the ice in the refrigerator finally melted almost. I checked all the places by the light of the refrigerator, and the water slowly flowed out from the side. Ah, there seems to be something blocking the drain pipe on the back wall of the refrigerator. I took it out with a toothpick and the water ran down from this drain. Nothing else is unusual. I wonder if something blocked the drain pipe and caused the freezer to freeze. So I did a little experiment.

That night, I cleaned all the water in the refrigerator, took two eggs and some fresh vegetables, then blocked the drain with sundries and closed the refrigerator door. There was a little frost on the refrigerator the next day, and a little more frost the next day. There was no ice in the dish two days ago, but the eggs and vegetables in it were a little frozen for three or four days. I melted the frozen wall of the refrigerator and took out the sundries in the drain pipe according to the above method. Add two more eggs and some fresh vegetables. The next day, there was no frost on the wall of the cold storage, only water droplets hung on it. The next day, there was still no frost on the wall of the cold storage. After four to five days of observation, the eggs and vegetables inside were not frozen. I know the answer. It turns out that this drainage is working. I repaired the refrigerator, and I was so happy!

Why does the drain pipe block the refrigerator and freeze? I'm confused. I checked the information about repairing the refrigerator. It turns out that the refrigeration principle of refrigerator freezer is like this. When cooling, the back wall frosts, the temperature drops, and then the cooling is stopped. When the frost melts and the temperature rises, the melted water should flow out along the outlet, enter the evaporator on the compressor, and then be evaporated by the heat of the compressor. The icing is caused by the blockage of the outlet. Don't put things too close to the back wall in the future, and don't let food scraps block the water outlet.

Through this incident, I understand that more observation, more reading and more thinking will give me unexpected gains.
