Recently, a new announcement was published on the Fujian Provincial Government Procurement Network. A college purchases refrigerators. It is worth noting that it is different from the refrigerators purchased in the past. This is a refrigerator equipped with UVC-LED sterilization function.
It is understood that this refrigerator adopts the dual sterilization technology of metal catalysis and UVC sterilization, which effectively removes harmful substances in the refrigerator, and the sterilization rate is 99.99%, which protects the health of the family. The purchase this time shows that the use of UVC LEDs in large home appliances has been recognized by consumers.
In fact, it is not the first time that UVC-LED has been used in refrigerators. “UV LED Wind Direction” has found that many big-name manufacturers have installed UVC-LEDs on their products, such as LG, Midea, Toshiba and so on.
South Korea's LG introduced the InstaView door refrigerator, which is equipped with "Hygiene Fresh+". LG's Hygiene FRESH+ is equipped with UVC-LED and a powerful fan. The powerful fan can inhale bacteria and odor particles, and remove them through a comprehensive system of UV LED lights, two antibacterial filters, and two deodorizing filters. The sterilization rate of the smart air filter reaches 99.999%.
Toshiba Corporation has released a new model of the freezer refrigerator "VEGETA". The vegetable room is equipped with a new "UVC-LED" with antibacterial effect. In addition to inhibiting the growth of bacteria attached to the surface of vegetables, it can be stored in a clean state. It also promotes the synthesis of antioxidants.
In China, there are also refrigerators of this type. Rumei refrigerators and Sanan Optoelectronics have joined forces to successfully develop the "space deep ultraviolet removal of pesticide residues technology."
This technology uses San'an Optoelectronics UVC high-power chips and the latest unique packaging technology. Its single package can effectively and stably output space deep ultraviolet radiation of more than 50mW. It is modularized through multiple deep ultraviolet UVC packages. Degradation of pesticide residues in refrigerator fruits and vegetables. Midea Guojing refrigerator uses high-power ultraviolet light output to strongly remove 79 kinds of pesticides in 4 categories and completely destroy pesticide residues. In SGS laboratory, Midea refrigerator pesticide residue removal technology tested the effectiveness of 12 categories of national food and drug supervision pesticide residue monitoring projects, and the comprehensive degradation rate was 92.1%-98.5%. It solves the worries of the consumers about the removal of pesticide residues and sterilization, and leads thousands of families to a healthy and green life.
Summary: The application of UVC-LED in refrigerators is a new direction for home appliances. Using its sterilization function to remove some bacterial residues and keep food fresh longer. Many home appliance brands have installed UVC-LEDs. It can be seen that the first-line home appliance brand factories are sterilizing. With increased awareness and active adjustments to specifications, UVC-LED has a great chance to become the standard configuration of home appliances.
