Air-cooled refrigerator antibacterial device and air-cooled refrigerator antibacterial control method

Abstract

The invention discloses an air-cooled refrigerator antibacterial device, comprising a housing. Opposite side walls of the housing are respectively provided with air inlets and air outlets. The air inlet side of the housing is provided with a fan. The air outlet side of the housing is provided with a sterilizing apparatus. The sterilizing apparatus comprises a titanium dioxide structure. The place of the titanium oxide structure is provided with a UV ozone lamp and a negative ion generator. The invention also discloses an antibacterial control method by using the air-cooled refrigerator antibacterial device. When the sterilizing apparatus works, hydroxyl, negative ions and ozone are produced to form a gaseous antibacterial agent with much stronger antibacterial and bactericidal effects than any one or the combination of any two of the above three. So the antibacterial and bactericidal effects are enhanced. The method of the present invention includes sending ozone, negative ions and hydroxyl of low concentration generated by the antibacterial device to every corner of upper, middle and lower shelves of the refrigerator by controlling a ventilation door switch. The ozone, negative ions and hydroxyl are continuously circulated under the action of the ventilation door to kill the bacteria in air and on the surface of foods in the refrigerator. Antibacterial test results show that the sterilization rate is greater than 90%.

Description

technical field [0001] The invention relates to the field of refrigerator antibacterial technology, in particular to an antibacterial device and an antibacterial control method by adjusting the on-off time of a damper and an ultraviolet lamp. Background technique [0002] With the continuous improvement of people's living standards, refrigerators have almost entered thousands of households, but in daily use, most people's wrong usage habits often make refrigerators become "bacteria boxes", which not only fail to keep fresh The effect of food, on the contrary, will have an impact on people's health. [0003] Generally, refrigerators use the method of lowering the temperature to inhibit the reproduction of microorganisms in food, catalyze enzymes and reduce the oxidation rate of food. But the low temperature can not completely freeze the bacteria to death, but it can slow down the growth of the bacteria; especially many microorganisms, such as Staphylococcus aureus, Escheric...

AI Technical Summary

Problems solved by technology

Its disadvantages are: for large-capacity refrigerators, this antibacterial fresh-keeping box has a small contact area with the air, and the antibacterial and deodorizing effects are uneven, and the carrier is a consumable resource that requires frequent manual replacement, which is troublesome for daily use

However, there is a lack of air-cooled refrigerator antibacterial devices and air-cooled refrigerator antibacterial control methods that can meet this demand in the market.
