Problems solved by technology

[0003] However, when using the infrared high-temperature disinfection method, the internal temperature of the cabinet needs to be heated to not lower than 100°C, and it needs to be kept warm for more than 15 minutes. The entire working cycle generally takes 30 minutes, and the disinfection speed is slow.
When the ozone disinfection method is used, the residues on the tableware will be oxidized into peroxides that are harmful to human health. If the ozone leaks, it will pollute the environment and endanger human health.
When using ultraviolet disinfection, it can only kill bacteria on the parts exposed to ultraviolet radiation, resulting in low disinfection efficiency
When using ozone plus ultraviolet disinfection methods, problems caused by ozone disinfection methods will also occur

[0122][Second embodiment] The light waves produced by the disinfection cabinet that have the effect of breaking the wall of bacteria are broadband light waves, which produce two main wavelengths of 253.7nm to 780nm with better bactericidal effect, and the content of ultraviolet light waves is 0.35% to 0.7%. . The heat energy generated by the disinfection cabinet is generated by the visible light and infrared rays in the generated broadband light waves, so that the temperature of the inner cavity of the disinfection cabinet can be raised to a range of 55°C to 120°C, thereby realizing the combination of light waves and heat energy. Sterilization.

[0123] Among them, through the control of current or voltage, the generated broadband light wave is controlled to control its minimum ultraviolet C wave irradiation intensity to 70μW / cm 2 and, through the control of the power supply frequency, the minimum ultraviolet C-wave radiation dose for digital control irradiation is 120000μW.s / ...

Abstract

The invention provides a disinfecting method of a disinfection cabinet and the disinfection cabinet. The disinfecting method adopted combined light waves and heat to sterilize and disinfect, wherein the light wave has a wall-broken effect on bacteria. The invention also provides the disinfection cabinet adopting the disinfecting method, which is composed of an outer shell and an inner shell, wherein the outer shell encircles the inner shell to form an interlayer, and the inner shell forms an inner cavity provided with a device for producing light waves having a wall-broken effect on bacteria and a device for producing heat capable of maintaining the disinfection cabinet inner cavity at a certain temperature. By the invention, sterilization and disinfection can be realized by combing light waves and heat, thus greatly shortening the disinfecting time.

Description

technical field [0001] The invention relates to the technical field of tableware disinfection, in particular to a disinfection method for a disinfection cabinet and a disinfection cabinet using the method. Background technique [0002] There are many types of tableware disinfection cabinets currently on the market, and the disinfection methods used are mainly as follows: Infrared high-temperature disinfection method, generally using infrared lamp heating, heating the internal temperature of the cabinet to a certain high temperature, to achieve high-temperature disinfection effect ;Ozone disinfection method, using the strong oxidation of ozone for disinfection; ultraviolet disinfection method, using ultraviolet lamps to generate sterilizing ultraviolet rays, to achieve the effect of ultraviolet radiation disinfection; ozone plus ultraviolet disinfection method, using high ozone ultraviolet lamps to generate ultraviolet rays at the same time Ozone is also produced to achieve t...
