Deodorization refrigerator

Abstract

The invention discloses a deodorization refrigerator. The deodorization refrigerator comprises a box and a deodorization device. The deodorization device comprises a shell. A first chamber, a second chamber, a third chamber and a fourth chamber are formed in the shell. The first chamber communicates with the third chamber. The second chamber communicates with the fourth chamber. At least the second chamber is internally provided with a filter part. The sidewall of the shell is provided with a cold air inlet communicating with the interior of the box in the position corresponding to the first chamber, a fresh air inlet communicating with the outside in the position corresponding the second chamber, a waste gas outlet in the position corresponding to the third chamber and a fresh air outletcommunicating with the box in the position corresponding to the fourth chamber. The first chamber is internally provided with a first draught fan used for sucking the air in the box into the first chamber. The fourth chamber is internally provided with a second draught fan used for discharging the air in the fourth chamber into the box. The second chamber and the third chamber can selectively communicate or close. The fresh air inlet and the waste gas outlet can both be selectively opened or closed.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a refrigerator capable of removing peculiar smell. Background technique [0002] The peculiar smell in the closed space of the refrigerator not only affects the user experience, but also generally causes consumers' health concerns about bacteria and viruses. However, the current built-in sterilization and deodorization modules have limited effects. Many consumers put bamboo charcoal bags, grapefruit peels and other odor absorption devices in the refrigerator, but problems such as limited adsorption capacity and easy failure still plague consumers. [0003] Existing commonly used deodorization technologies include: photocatalysis, activated carbon, silver ions, low-temperature plasma, etc. For example, a refrigerator disclosed in Chinese Patent Application No. 201310358839.8 includes a refrigerating room, and a photocatalyst device is arranged in the refrigerating room. , whe...
