Refrigerator disinfecting and deodorizing purifier

Abstract

The invention discloses a refrigerator disinfecting and deodorizing purifier. The refrigerator disinfecting and deodorizing purifier comprises a shell, a metal grille is mounted at the upper end of the shell, a hole is formed in the center of the metal grille, a power supply, a variable-voltage frequency converter, a variable-frequency variable-voltage ionizer and an ionic wind transmitting metal pinpoint are mounted in the shell, the variable-voltage frequency converter is used for converting a high-voltage electric field, the variable-frequency variable-voltage ionizer is used for outputting the high-voltage electric field to the metal grille, the ionic wind transmitting metal pinpoint is used for receiving the high-voltage electric field outputted by the variable-frequency variable-voltage ionizer, the power supply, the variable-voltage frequency converter and the variable-frequency variable-voltage ionizer are sequentially connected, the ionic wind transmitting metal pinpoint and the metal grille are connected with the variable-frequency variable-voltage ionizer, the ionic wind transmitting metal pinpoint is positioned below the metal grille, and the pointed end of the pinpoint faces the center of the hole directly. The refrigerator disinfecting and deodorizing purifier is capable of disinfecting and deodorizing for 24 hours continuously, eliminating various microorganisms in air and the surfaces of the spaces of a refrigerator effectively, reducing airborne suspended particulate matters remarkably and removing peculiar smell and odor remarkably.

Description

technical field [0001] The invention relates to a purifier, in particular to a refrigerator disinfection and deodorization purifier. Background technique [0002] Refrigerator is an essential electrical appliance in household life, and its penetration rate in cities has exceeded 90%. Few people know that the low temperature environment in the refrigerator can also make food multiply harmful microorganisms and become a health killer. A family hygiene report released by the Global Health Council Association shows that refrigerators in 46% of households failed to pass the bacteria test, and refrigerators in 44% of households showed signs of mold reproduction and expansion. Even more so than the toilet seat. In 2016, the China Food and Drug Administration issued the "Risk Warning on Preventing Listeria Contaminating Food", stating that the bacteria in the refrigerator has become an important factor threatening food safety. Those who are most likely to be infected by this bact...

AI Technical Summary

Problems solved by technology

The total amount of ozone generated per hour of refrigerator ozone purifiers in the market is only a few milligrams, the concentration is low, and it is only turned on for a few minutes per hour, so it cannot achieve a good refrigerator space and food sterilization effect

[0007] 3) Ultraviolet light has a bactericidal effect, but there is no bactericidal effect on the backlit surface, and it cannot sterilize in all directions at 360 degrees

Ultraviolet radiation is harmful to human health, especially in the family, ignorant children open the refrigerator and there is a safety risk

[0008] 4) Plasma or negative ion refrigerator disinfection purifiers appearing on the market, due to the low concentration of the ion generator outlet (only tens of thousands to several million per cubic centimeter), after diffusing into the refrigerator space, the average negative ion concentration per cubic centimeter of the space is only a few Hundreds to tens of thousands, due to the low concentration of negative ions and the absence of ion air flow that can evenly diffuse negative ions to all corners of the refrigerator, there are generally defects of poor sterilization and deodorization effects, especially harmful microorganisms that breed on the surface of food

[0009] 5) The air filter type refrigerator purifier only sterilizes and deodorizes the inhaled air, and has no inhibitory or bactericidal effect on the microorganisms that grow on the food stored in the refrigerator

The sterilization, deodorization and purification effect of this intermittent disinfection and deodorization mode is far inferior to the effect of continuous 24-hour purification, and battery replacement also causes inconvenience in use and increases operating costs

[0011] 7) Small insects such as flying insects and maggots that can survive in low-temperature environments will appear in the refrigerators of household refrigerators, endangering food

[0012] The common disadvantages of the above refrigerator purifiers are: 1) the air in the refrigerator storage space and the surface of the food are poorly disinfected; 2) the deodorization effect is poor; 3) the deodorization cannot last for 24 hours without interruption; 4) the ozone concentration is high; 5 ) is ineffective against insects that breed in the refrigerator; 6) Refrigerator purifiers whose ozone does not significantly exceed the standard cannot achieve all the purification indicators of the refrigerator's internal environment.

[0013] All in all, the refrigerator disinfection and deodorization purifiers currently on the market have not yet seen a healthy refrigerator space environment index that can fully meet the following standards for a clean refrigerator space environment without biological and odor pollution
