Sterilization surface light source and refrigerator

Abstract

The invention provides a sterilization surface light source and a refrigerator. The sterilization surface light source comprises a light guide plate and a light source. The light source is installed on the light guide plate. Light emitted by the light source is emitted out through the outer surface of the light guide plate. A catalyst coating is arranged on the outer surface of the light guide plate and can absorb light emitted by the light source to perform sterilization. According to the sterilization surface light source, due to the arrangement of the light guide plate, light emitted by a point light source or a line light source can achieve the illumination effect of the surface light source, and therefore the light is softer, a larger region can be covered with the light, and a high-end illumination effect is achieved. Due to the fact that the catalyst coating is arranged on the plate face of the light guide plate, the sterilization problem of the refrigerator is easily solved according to the principle that the catalyst coating absorbs optical energy to kill bacteria.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a sterilizing surface light source and a refrigerator comprising the bactericidal surface light source. Background technique [0002] Studies have found that as the storage time of refrigerators increases, harmful bacteria such as Escherichia coli, Staphylococcus aureus, Salmonella, and mold will multiply on the surface of the food, which may endanger human health. In order to solve the above problems, many sterilization technologies are applied to refrigerators, such as photocatalyst sterilization, plasma sterilization, etc. However, there are various problems in the above sterilization technologies, such as: some devices need to be added to the refrigerator, such as fans, high pressure Bags, etc., occupy the volume of the refrigerator, and will lead to changes in other structures of the refrigerator; or require some harsh conditions to achieve the sterilization effect, re...
