Sound comes from two aspects:

One is "solenoid valve opening and closing";

When the temperature of the refrigerator is too high, the compressor starts to work-the "electromagnetic valve" that controls the circulation of the refrigeration parts is opened;

The odor in the refrigerator is mostly caused by the long storage time of food. Therefore, the food in the refrigerator should be cleaned up in time and the leftovers should be eaten as soon as possible. If food is found to be spoiled, it should be thrown away immediately. At the same time, after disconnecting the power supply, thoroughly clean the inside of the refrigerator with neutral detergent and warm water to eliminate pathogenic bacteria. A large number of microorganisms are easily attached to the handle and sealing strip of the refrigerator, which will pollute the food and produce deterioration and odor after entering the refrigerator. Therefore, it is necessary to wipe the handle and sealing strip with alcohol frequently to achieve the purpose of sterilization and disinfection.

Fish and fishy food should be cleaned, dried, put into edible plastic bags, tied tightly, and then put in the refrigerator. This can prevent crosstalk and keep the original flavor of food.
