Description

Refrigerator with a refrigerator body Technical Field The utility model relates to the field of refrigeration equipment, in particular to a refrigerator. Background Refrigeration devices are devices that are used to maintain freshness of food, pharmaceutical products, etc. or to provide a comfortable temperature for a work environment by lowering the temperature or removing heat from a space. Common refrigeration equipment includes refrigerators, air conditioners, freezers, refrigerated vehicles, and the like. The storage space of the existing refrigerator products is generally a closed space due to the problem of heat preservation structures. When the refrigerator is used for storing chemicals or articles easy to emit peculiar smell, the refrigerator body is closed, so that the peculiar smell in the refrigerator can not be effectively removed, and the gaseous pollutants can harm the health of human bodies when serious. At present, common deodorizing technologies comprise photocatalysis, active carbon, silver ions, low-temperature plasma and the like, and as the purifying mode of the air in the refrigerator is internal circulation, the technology is limited by a filtering material filtering principle, purifying efficiency and service life, the effect is very limited, and the problem cannot be solved yet due to the peculiar smell adsorption device adopted by consumers. Disclosure of utility model The present utility model provides a refrigerator that can solve the problems set forth in the background art described above. The refrigerator comprises a refrigerator body, wherein a volume cavity for storing articles is formed in the refrigerator body, the refrigerator body is connected with a fresh air device, the fresh air device comprises an air pipe assembly, the air pipe assembly is used for communicating the volume cavity with the external environment, and the fresh air device further comprises a filtering assembly, and the filtering assembly is used for filtering circulating gas. Preferably, the air pipe assembly comprises an air inlet pipe, a fresh air pipe, an air return pipe and an exhaust pipe, wherein the air inlet pipe is matched with the fresh air pipe to convey air in the external environment into the volume cavity, and the air return pipe is matched with the exhaust pipe to exhaust air in the volume cavity to the external environment. Preferably, the output end of the air inlet pipe is provided with an air inlet valve, and the output end of the return air pipe is provided with an air exhaust valve. Preferably, the fresh air pipe input is provided with an air supply fan, and the exhaust pipe input is provided with an exhaust fan.
