Background
With the development of science and technology, people pay more and more attention to health and the improvement of the environment in the existing refrigerator. Along with the use of the refrigerator, the odor tainting problem of the refrigerator is more and more prominent, which is particularly shown in a single-cycle air-cooled refrigerator, and along with the promotion of the industry standard on antibiosis and odor removal, the sterilization and odor removal technology in the refrigerator is more and more.
In the prior art, a plurality of modules are used for sterilizing and removing peculiar smell, and a plurality of auxiliary devices such as small fans and the like are needed. The surface module occupies the space in the refrigerator, and on the other hand, the sterilization and odor removal efficiency is not high. For example, in the Chinese patent 'refrigerator with sterilizing and deodorizing coating on air duct and its purification control method', the publication number is: CN111457653A, its sterilization is clean to be scribbled on the fan and the coating is on air-out separate net or return air separate net, and the area is less, and the bactericidal effect often is unsatisfactory. There may also be a shedding phenomenon.
The research finds that the nano zinc oxide and the nano silver are two inorganic antibacterial agents which are widely applied and researched. The nano silver shows stronger bactericidal performance due to the surface effect, the quantum size effect and the like, and plays an important role in the field of antibacterial agents.
Although the nano silver has strong antibacterial performance, the manufacturing cost of the nano silver is high, and the wide application of the nano silver is limited to a great extent. The nano silver and the nano zinc oxide are combined to form the composite nano material, the cost can be reduced by reducing the using amount of the nano silver, and meanwhile, the composite antibacterial material effectively combines the antibacterial performance of the two antibacterial agents and is improved on the basis of the original antibacterial performance.
