Nanometer TiO2 sterilizing, disinfectant and deodorant assembly for refrigerator as well as preparation method thereof and disinfection and deodorization method

Abstract

The invention discloses a nanometer TiO2 sterilizing, disinfectant and deodorant assembly for a refrigerator as well as a preparation method thereof and a disinfection and deodorization method. The nanometer TiO2 sterilizing, disinfectant and deodorant assembly comprises quartz groove plates of which the surface is coated with a TiO2 layer and a fan and an ultraviolet lamp which are arranged on the quartz groove plates. The quartz groove plates instead of the refrigerator partition plates are detachably inserted inside the refrigerator; the ultraviolet lamp and the fan are opened, and since TiO2 is a photocatalytic oxidant, TiO2 is irradiated by virtue of the ultraviolet lamp inside the refrigerator to generate strongly oxidizing radical groups under the joint action of water and oxygen in water so as to achieve the sterilizing, disinfectant and deodorant effects; the fan is used for promoting the convection of air inside the refrigerator to enhance the sterilizing, disinfectant and deodorant effects; when the quartz groove plates are used in a long term, TiO2 on the surface of the quartz groove plates can be gradually decreased so that the sterilizing, disinfectant and deodorant effects are weakened, the quartz groove plates need to be taken out, the TiO2 film on the surfaces of the quartz groove plates is removed, the prepared nanometer TiO2 solution is plated on the surfaces of the quartz groove plates again and the quartz groove plates are inserted inside the refrigerator for repeated use.

Description

technical field [0001] The invention relates to a method for disinfecting, sterilizing and deodorizing a refrigerator freezer, in particular to nano-TiO 2 Disclosed are a disinfection, sterilization and deodorization component, a preparation method thereof, and a sterilization and deodorization method. Background technique [0002] The commonly used refrigeration temperature for storing food in the refrigerator is 4°C to 8°C. In this environment, the reproduction speed of most bacteria will slow down. However, there are some bacteria and germs that can not only survive in low temperature conditions, but also reproduce faster. Even in the freezer at minus 18°C, there are still bacteria with strong antifreeze ability that will survive. This kind of bacteria is called For psychrophilic bacteria, such as Yersinia, Listeria and so on. At the same time, these bacteria will produce many metabolic gases in the process of growth and metabolism, such as methane, hydrogen sulfide and...

Problems solved by technology

This method makes good use of the photocatalytic properties of nano-titanium dioxide to sterilize and deodorize. However, if nano-titanium dioxide is coated on the surface of the metal mesh, long-term use will cause the aging or even failure of nano-titanium dioxide. Users need to replace the metal mesh regularly, which is costly and unnecessary. Convenience, which limits the popularization and application of this method
