1, high temperature sterilization
At present, most washing machines have the function of high-temperature sterilization, that is, protein of microorganisms and enzymes are solidified or denatured by high temperature, which is the most extensive and easy sterilization method. However, it also has some limitations, requiring clothes to be able to withstand high temperatures, and materials such as silk are not suitable.
2. Ozone sterilization
Most washing machines using ozone sterilization technology in the market have added ozone generators inside. Before washing and the last rinsing, the internal ozone generator injects an appropriate amount of ozone into the inner cylinder, and the ozone interacts with water molecules to form ozone water, thus realizing the functions of deodorizing and sterilizing clothes, and automatically converting the ozone water into oxygen after sterilization without causing secondary pollution. Moreover, ozone water can also enhance the decontamination ability of detergents and improve the cleanliness of washing machines.
3, silver ion sterilization
There are three main ways of silver ion sterilization: ordinary silver ion sterilization, photodynamic silver sterilization and nano-silver ion sterilization. No matter what kind of silver ion sterilization technology, it is necessary to avoid the pollution of heavy metals to water, and it may no longer have sterilization effect after a certain period of use.
4, electrolytic water sterilization
Strong alkaline electrolyzed water has a good cleaning effect, while strong acidic electrolyzed water has a broad-spectrum, efficient and rapid sterilization effect. The washing machine with electrolyzed water sterilization technology uses the strong acidity and alkalinity produced by water electrolysis to sterilize and disinfect in a short time. Low production cost, convenient preparation, quick sterilization and no residue.
5, ultraviolet sterilization
This technology belongs to pure physical sterilization, and ultraviolet rays can destroy and change the DNA structure of microorganisms, thus sterilizing; Photocatalyst is a washing machine, which makes water flow through a timely spiral sleeve with short-wave weak ultraviolet radiation and the inner wall coated with photocatalyst to sterilize the water in the tube, and then returns to the barrel through dynamic spraying. In this process, the photocatalyst is irradiated by ultraviolet rays to produce titanium ions with strong oxidation ability, which can decompose or treat harmful substances and bacteria in water and clothes harmlessly.
