Four defrosting methods commonly used in refrigerators

Elaborate:

Method 1 of defrosting refrigerator: soft towel repeatedly wipes thin cream; Thawing method 2: put the boiling water in the aluminum lunch box into the freezer; Defrosting method 3: turn off the switch to defrost naturally; Defrosting method 4: stick a slightly thicker plastic film on the frost wall, and then remove the jitter.

Detailed:

The first one: I successfully thawed my refrigerator last week. I am very smart. Let's laugh.

First, put the contents of the freezer into the freezer, so that the best time to defrost the refrigerator is when there are few things in the refrigerator.

Step two, unplug the refrigerator. There may be a switch on the panel of a higher-grade refrigerator. Please turn it off in a civilized way. First turn off the switch, and then unplug the power.

Step three, open the refrigerator door and take out all the drawers. This step, the key is to take out the drawer, just take this opportunity to clean the drawer.

Step four, that's the beauty. Use a wet soft towel (preferably a clean scouring pad) to repeatedly wipe off the frost and dry the water in the refrigerator. The purpose of this is to speed up thawing and prevent food from deteriorating due to thawing. Rub the thick frost a few times, which will accelerate the melting of the frost. Never use sharp objects to forcibly defrost.

Step 5, after thawing, wipe it clean with a soft cloth.

Step 6, turn on the power supply of the refrigerator, wait until the temperature reaches the set temperature, and then move the food in the freezer to the freezer.

Generally, the defrosting process takes 1-2 hours, depending on the thickness of the frost. Don't worry about food going bad. The role of refrigeration is not small. It stopped for about 4-5 hours and the food hasn't thawed yet. Very good.

Precautions:

1. Don't open the refrigerator door when defrosting.

2. When cleaning the refrigerator drawer, try not to use detergent, because the refrigerator is closed and the smell of detergent is not easy to disperse.

Be sure to clean the freezer after thawing. If there are water droplets left, they will soon turn into frost.

The second type:

The refrigerator without automatic defrosting device can be quickly defrosted by the following methods: first, disconnect the power supply of the refrigerator and take out the food in the refrigerator; Then according to the size of the freezer, fill one or two aluminum lunch boxes with boiling water and put them into the freezer. After a few minutes, the frost on the freezer wall begins to fall off (if it doesn't fall off, you can gently pull it by hand).

If there is no metal evaporation plate at the top of the freezer, the lunch box filled with boiling water should be covered to avoid the deformation of the plastic inner wall due to sudden temperature rise at low temperature. This method is much more time-saving than simply defrosting without electric heating.

The third type: generally, the direct-cooling (frosting) refrigerator should be defrosted regularly (usually for one month), that is, unplug the power plug and wait until it thaws, then plug it in and run for two hours before putting food in.

Reminder: If this phenomenon (frosting and freezing) occurs again two weeks after defrosting, you should immediately call the maintenance center of this brand for on-site inspection (there should be a problem with the refrigeration system).

If a cold (frost-free) refrigerator freezes, there is no doubt that something is wrong.

The answer of a refrigeration senior technician!

Fourthly, some refrigerators need defrosting, and manual defrosting of refrigerators is time-consuming and laborious, and the defrosting effect is not good. Here's a good idea for defrosting.

According to the size of the freezer, cut a slightly thicker plastic film and stick it on the frosted wall of the freezer without using any glue. When defrosting, take the food out of the refrigerator temporarily, then take down the plastic film and shake it, and the frost will fall off completely. Then put a layer of film on it and put it in the food for further use.

Laboratory ultra-low temperature refrigerator:

The "Billion Times" series of ultra-low temperature refrigerators in the laboratory imported advanced German technology and produced with internationally renowned brand parts, with stable performance and reliable operation.
