Problems solved by technology

In recent years, the refrigerator industry has used ozone generators to kill bacteria in refrigerators. Ozone is a highly efficient bactericidal substance that can kill bacteria on food in refrigerators. However, when the concentration is high, it is harmful to the human body and has an odor. It is heavy and difficult for users to accept. Therefore, this method has not been popularized and applied in the refrigerator industry

Embodiment 1

[0014] Such as figure 1 Shown, photocatalyst negative ion sterilizing refrigerator of the present invention is made of freezer 1, freezer 2, freezer door 3, freezer door 4, freezer evaporator 5, freezer evaporator 6, freezer drawer 7, freezer compartment 8. The water receiving tank 9 and the refrigerator lamp 10 are all coated with a layer of negative ion photocatalyst coating on the surface of the liner of the refrigerator 2, the surface of the shelf 8 of the refrigerator, the inner surface of the door 4 of the refrigerator, and the outer surface of the fruit and vegetable chamber 13. Membrane 12, negative ion photocatalyst coating film 12 can be by means of the outside light when opening the door, or the lighting light in the cold room 2 to stimulate and produce negative ions with bactericidal effect and sterilizing ions such as hydroxyl groups with strong bactericidal effect, so that cold storage The room 2 is full of negative ions, and by controlling the working time of th...

Embodiment 2

[0016] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that an ultrasonic generator 11 is added in the refrigerator compartment 2. When the refrigerator compartment door 4 is closed, the ultrasonic generator 11 is activated instead of a lighting lamp. The sound energy excites the negative ion photocatalyst coating film 12 to work to generate a large amount of negative ions, and controlling the working time of the ultrasonic wave can control the generation of negative ions in the refrigerator, thereby controlling the sterilization time.

Embodiment 3

[0018] Such as image 3 , Figure 4 Shown, photocatalyst negative ion sterilizing refrigerator of the present invention is made of freezer 1, freezer 2, freezer door 3, freezer door 4, freezer evaporator 5, freezer evaporator 6, freezer drawer 7, freezer compartment 8, water receiving tank 9, cold room lamp 10, fruit and vegetable room 13, increased an ultraviolet ozone generating device 14 in the cold room 2, the ultraviolet ozone generating device 14 is by the box body 15, the ultraviolet lamp tube 16 that one end is installed in the box body 15 1. The miniature electric fan 17 that the other end is installed in the box body 15 constitutes, is coated with negative ion photocatalyst coating film 12 on the box body 15 inner surface, is respectively worn with air outlet hole 18 and air inlet hole 19 on the two end faces of box body 15, in A light-shielding plate 20 is installed in the end face of the ultraviolet lamp tube 16 side, and the light-shielding plate is made of a div...

Abstract

The photocatalyst and negative ion sterilized refrigerator includes cold storage and negative ion photocatalyst coating painted to at least one of inner surface of the cold storage, the surface of shelf, the inner surface of the door or outer surface of the fruit and vegetable chamber. Owing to the negative ion photocatalyst coating, low concentration ozone, great amount of sterilizing negative ions, powerful sterilizing hydroxyl radicals and other sterilizing ions may be produced inside the refrigerator under the irradiation of ultraviolet or visual light to sterilize the matters inside the refrigerator.

Description

technical field [0001] The invention relates to a sterilizing refrigerator, in particular to a photocatalyst anion sterilizing refrigerator. Background technique [0002] The refrigerator freezer is mainly used to store fruits and vegetables, fresh food, leftovers and so on. As we all know, the temperature in the freezer compartment of the refrigerator is low, generally between 0°C and 10°C. Due to the low temperature, the activity of microorganisms is significantly reduced, and the speed of food spoilage is significantly slowed down. Therefore, refrigerators have been widely used in today's society. . However, the refrigerator is not a safe, and the food stored in the refrigerator, especially the food stored in the cold room, will still rot. According to the research of microbiologists and food scientists, food spoilage is mainly caused by bacteria and molds. There are many types of bacteria, and different bacteria grow and reproduce at different ambient temperatures. Mi...
