Many people regard the refrigerator as a “food sterilizer†at home, and think that the food stored in the refrigerator is hygienic. In fact, the refrigerator does not clean often because it stores food for a long time, and it breeds many bacteria. Although the food in the refrigerator looks fresh, it has actually deteriorated. The storage time of cooked meat in the refrigerator should not exceed 4 days.
The common refrigerating temperature for storing food in the refrigerator is 4 to 8°C. In this environment, most bacteria grow at a slow speed. However, some bacteria are psychrophilic, such as Yersinia, Listeria, etc. At this temperature, they can rapidly grow and multiply. If foods that are infected with this kind of bacteria are eaten, they will cause intestinal diseases. In the freezer of a refrigerator, the temperature is generally around minus 18 degrees Celsius. At this temperature, bacteria are generally suppressed or killed. Therefore, there is a better preservation effect of foods stored inside. However, freezing does not mean that it can be completely sterilized, and some bacteria with strong antifreeze ability will survive. Therefore, from another perspective, if the refrigerator is not sterilized frequently, it will become a “hotbed†for some bacteria.
The storage time of any food in the refrigerator should not be too long. It is best to buy it with food. Because the storage time is too long, it will not only affect the taste of the food, but also cause odors. There are also some fruits, such as bananas, apples, etc. If they are put for a long time, they are easily degenerate. Once they are degraded, they will emit a harmful gas. Do not store too much food in the refrigerator. This will cause the outside temperature of the food to be low and the internal temperature to be high to cause deterioration.
The refrigeration of the refrigerator is realized by the rotation of the refrigerator compressor. Due to the principle of electromagnetic induction, the rotation of the Motor generates a certain amount of electromagnetic energy, thereby forming a certain electrostatic voltage on the housing of the refrigerator. Any type of household appliance (including TVs, refrigerators and other household appliances) with sensing elements need to have a certain electrostatic voltage at the moment of starting and stopping as long as they are not grounded. (The TV screen will also generate certain static electricity at the moment of switching, we When you touch the screen with your hand, there will be noises. Because the electrostatic voltage itself is very small, it will not cause any harm to the human body. In spite of this, refrigerators must be reliably grounded when they are used as a type of appliance, otherwise there is a risk of electric shock if the insulation itself fails. Therefore, it is necessary and necessary to install the grounding wire.
In addition to the above several methods of use to be aware of, consumers should also learn how to maintain their own refrigerator, make it use longer: specific methods are as follows:
1. The refrigerator should be cleaned periodically (at least 2 times per year). When cleaning the refrigerator, first cut off the power supply, use a soft cloth to dipped in water or utensils, gently scrub, and then wipe the detergent with clean water.
2, in order to prevent damage to the coating layer outside the box and plastic parts, do not use detergent, detergent powder, talcum powder, alkaline detergent, water, water, oil, brushes and other cleaning refrigerator.
3, when the inside of the cabinet is dirty and fouled, it should be removed and cleaned with clean water or detergent. Wipe the surface of electrical parts with a dry cloth.
4. After cleaning, plug the power plug firmly and check if the temperature controller is set in the correct position.
5. When the refrigerator is not in use for a long time, unplug the power plug and clean the inside of the box. After the box is fully dried, close the box door.
