The refrigerator is one of household appliances, and basically, each household has at least one refrigerator which can be used for a long time. The refrigerator has the fresh-keeping and corrosion-preventing functions on food, and is refrigeration equipment capable of keeping constant low temperature, so that the time for delaying food spoilage is achieved through the constant low temperature condition.

In daily use of a refrigerator, the variety of stored food materials is various, including meat, vegetables, fruits, dry goods, beverages and the like, wherein the food materials are mixed in raw and cooked state, and various sewage, dirt, garbage and the like can be contained in the stored food of the refrigerator. Due to the cold environment in the refrigerator, under the condition of frequent switching, water vapor in the air is liquefied into water mist to dissolve dirt in the refrigerator and on the surface of food materials, and when sewage is discharged from the drain hole, the pipe diameters of the drain hole and the drain pipe are small and are only 5mm-10mm, so that the internal blockage of the drain pipe is easily caused by the sewage in which foreign matters are dissolved, and the internal sanitation of the refrigerator is influenced.

If a drain hole of the refrigerator is blocked, pollutants in a fresh-keeping layer can be deposited, dirty pollutants such as sewage, meat blood and the like which are rich in organic matters form a hotbed of bacteria, and some mesophilic bacteria and psychrophilic bacteria can live and propagate at a lower temperature, such as Listeria, salmonella, Shigella, Yersinia and the like. Once these bacteria multiply in large quantities, they are extremely harmful to the intestines and stomach of human body, and can cause abdominal pain, diarrhea, nausea, vomiting, acute gastroenteritis and the like in different degrees, and in severe cases, they can also cause septicemia and meningitis, thus endangering life safety.
