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

[0012] As shown in Fig. 1 and Fig. 2, the photocatalyst anion sterilizing refrigerator of the present invention comprises a freezer 1, a freezer 2, a freezer door 3, a freezer door 4, a freezer evaporator 5, a freezer evaporator 6, and a freezer Drawer 7, refrigerating compartment shelf 8, sink 9, refrigerating compartment lamp 10 and fruit and vegetable compartment 13, in refrigerating compartment 2, comprehensive sterilizing device 11 capable of producing ozone, hydroxide and negative ions is installed, and comprehensive sterilizing device 11 consists of box Body 17, the ultraviolet light tube 16 that one end is installed in the box body 17, the miniature electric fan 18 that the other end is installed in the box body 17 constitutes, is coated with negative ion photocatalyst film 19 on the box body 17 inner surface, and the two end faces of box body 17 respectively The air outlet hole 20 and the air inlet hole 12 are worn, and a light shield is installed in the end face of th...

Embodiment 2

[0014] As shown in Figures 1 and 3, the difference between this embodiment and Embodiment 1 is that the inner surface of the box body 17 of the comprehensive sterilization device 11 is coated with TiO 2 The photocatalyst film 21 is also equipped with a negative ion generator 22 in the box body 17 . When the refrigerator was in the sterilizing state, the ultraviolet lamp 16 in the comprehensive sterilizing device 11, the miniature electric fan 18 and the negative ion generator 22 worked simultaneously, and the titanium dioxide coating film on the inner surface of the comprehensive sterilizing device 11 was irradiated by ultraviolet rays to produce a strong At the same time, under the irradiation of ultraviolet rays, part of the oxygen in the air will be converted into ozone, and at the same time, the negative ion generator 22 will generate negative ions. The chamber 2, the inner surface of the refrigerating chamber 2 and the food in the refrigerating chamber 2 are thoroughly st...

Abstract

The photocatalyst and negative ion sterilized refrigerator includes cold storage and comprehensive sterilizing device installed inside the cold storage to generate ozone, hydroxyl radical and negative ion. On the inner surface of the box of the comprehensive sterilizing device, negative ion photocatalyst is painted, which is formed through spraying neutral liquid with nanometer TiO2 and piezoelectric crystal tourmaline powder and has photocatalyst property and can generate great amount of sterilizing negative ions under the action of weak light energy, mechanical energy, sound energy, etc. For example, negative ion photocatalyst painted on indoor wall can reach negative ion concentration in the indoor air up to 1600 / cu cm and sterilizing rate up to 99.99 %.

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 relatively low, generally between 0°C and 10°C. Due to the low temperature, the activity of microorganisms is significantly reduced, and the rate 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 tempera...
