1. The inside of the refrigerator should be maintained at about 4℃, so that the food stored in the refrigerator can be kept for a long time. If hot things are put directly into the refrigerator, the temperature in the refrigerator will rise, and the condition that the inside of the refrigerator should be maintained at about 4℃ will not be reached, and the food stored in the refrigerator is easy to deteriorate.
2. When hot things are put into the refrigerator, some heat is brought into the refrigerator, and the refrigerator needs to work to lower the temperature, which requires power consumption and increases the burden of the refrigerator, thus reducing its life.
3. Because the temperature in the refrigerator is low, when the hot food is cold, the contained water will evaporate rapidly and then solidify on the internal evaporator, and a thick frost layer can be formed on the evaporator in a short time, which prevents the evaporator from transferring the heat in the refrigerator to the outside.
The refrigerator should not be too full, and appropriate space should be left to facilitate the cold air to penetrate all the storage. In addition, the refrigerator should be disinfected regularly. Wipe the refrigerator once every 3-4 weeks with dilute bleaching powder water or 0. 1% potassium permanganate water, and clean the refrigerator regularly, including all layers, especially the filter screen, where dirt and germs often accumulate.
Regular and proper maintenance can prolong the service life of refrigerator. Be sure to unplug the refrigerator before maintaining it.
1. Always clean the dust on the condenser and compressor on the back or bottom of the refrigerator. You can use a vacuum cleaner or a brush to remove dust. Be careful not to wipe the dust on the refrigerator and compressor with wet cloth.
2. When the refrigerator is out of service for a long time, you should first cut off the power supply, take out all the food in the box, clean the inside and outside of the box, and open the door for several days to make the box fully dry and disperse the odor in the refrigerator.
3. Check the drain pipe. If the drain pipe is blocked, water will leak into the refrigerator. Poke the drain pipe with a wire to remove the things accumulated on the drain pipe.
4. Don't neglect the cleaning of the door sealing strip. Dilute the bleach with 10 times of water, then dip it in a toothbrush and clean it. Finally, rinse the bleach with water. The adhesive tape is dirty and easy to age, which will affect the tightness of the refrigerator and increase power consumption.
5. Check the vibration, noise and the temperature of the compressor. When touching the compressor shell during operation, there should be no obvious vibration, and the compressor should not be obviously started during the day.
6. Pay attention to check whether there are cracks on the power cord to prevent leakage.
7. Wash and dry the inside and outside of the refrigerator with warm water or neutral detergent, and open the refrigerator door for ventilation and drying for one day.
