In this embodiment, the walls of the water outlet pipe 51, the first water return pipe 52 and the second water return pipe 53 are all made of heat conductive material.

The working process of the invention is as follows:

1. steam sterilization stage: when the water in the water tank 5 is heated to a certain temperature, the first control valve 101 is opened, the water vapor enters the airflow channel 30 through the first control valve 101, and then enters the inner container 2 to steam-sterilize the tableware, at this time, the water pump 7 and the second control valve 102 are both closed, and the airflow channel 30 is not heated. The penetrability of steam is strong, and protein, protoplasm colloid warp the solidification easily under the damp and hot condition, and the enzyme system destroys easily, and steam gets into intracellular condensation and becomes water, can emit latent heat and raise the temperature, and then reinforcing power of disinfecting.

2. Ultraviolet and ozone sterilization stage: the ultraviolet lamp 9 is turned on, and the ultraviolet lamp 9 emits ultraviolet rays to irradiate the tableware to be sterilized while generating ozone. Since the first heating means 6 is provided at the bottom of the water tank 5, the heating of the water in the water tank 5 by the first heating means 6 does not affect the ozone in the inner container 2. The fan 4 is opened, the mixed gas of the air in the inner container 2 and the ozone rapidly enters the air flow pipe 3 through the air inlet 31 to be premixed, the premixed gas enters the fan 4 to be secondarily mixed, and the fully mixed gas flows back to the inner container 2 through the air outlet 32, so that the ozone is rapidly and uniformly distributed in the inner container 2. The ultraviolet sterilization has the advantages of high efficiency, broad spectrum, safety, reliability and the like, but has poor effect of killing spores, cysts and viruses, and has to be pretreated when treating articles with water, because the ultraviolet can be absorbed by a plurality of substances in the water, and in addition, because of the existence of an irradiation shadow plane, the ultraviolet sterilization generally has sterilization dead corners. Ozone sterilization is a bacteriolytic method, has thorough sterilization, no residue, broad spectrum sterilization, can kill bacterial propagules, spores, viruses, fungi and the like, and can destroy botulinum toxin, and ozone is gas. According to the invention, through the design of the airflow channel 30, ozone can be rapidly and uniformly distributed in the inner container 2, and no dead angle exists in sterilization.

3. Ozone rapid decomposition/high temperature sterilization stage: after ozone distributes evenly in inner bag 2, open water pump 7 and second control valve 102, hot water gets into outlet pipe 51 under water pump 7's effect, thereby heat airflow tube 3, ozone in airflow channel 30 is decomposed like this, air in airflow channel 30 is heated simultaneously, air after the heating gets into inner bag 2, carry out pasteurization to the tableware of treating disinfecting in inner bag 2, hot water in outlet pipe 51 gets into first return water pipe 52 through second control valve 102 simultaneously, utilize the waste heat to heat inner bag 2, promote pasteurization's effect. In addition, airflow channel 30 can carry out the secondary heating to the steam in the air current, can not only avoid vapor condensation in air current pipe 3, makes vapor get into the saturated condition through carrying out secondary heating energy to vapor moreover to further convert superheated steam into, superheated steam's penetrability is stronger, and then can destroy the enzyme system of bacterium more fast, further promotes the effect of killing to the bacterium.

4. And (3) a cooling stage: after the high-temperature sterilization is finished, the temperature of the surface of the tableware is higher, and in order to avoid scalding when a user takes the tableware, a cooling step is added to the disinfection cabinet after the sterilization is finished. The specific process is as follows: the first heating device 6 is closed, the second control valve 102 is communicated with the water outlet pipe 51 and the second water return pipe 53, water in the water tank 5 is rapidly cooled through the heat dissipation device 8 under the action of the water pump 7, the airflow pipe 3 is also rapidly cooled with cold water, and cooled air enters the inner container 2 from the air outlet 32 to cool the disinfected tableware. In the cooling process, whole inner bag 2 is still in inclosed state to can effectively avoid causing secondary pollution to the tableware after the disinfection, and steam can cool off fast, and the comdenstion water in the temperature change passageway 30 flows back to the water tank 5 through steam outlet 301 along the temperature change passageway 30, and the comdenstion water in the inner bag 2 is through looping through air inlet 31, steam outlet 301 backward flow to the water tank 5 in simultaneously, thoroughly avoids the outer problem of arranging of steam.

According to the invention, the airflow channel 30 is arranged in the box body 1 of the disinfection cabinet, and the organic combination of multiple sterilization means is adopted, so that the sterilization efficiency is obviously improved, the sterilization effect is improved, and the high-efficiency disinfection is realized. In the disinfection cabinet, steam sterilization can be independently adopted for independent steam disinfection in the disinfection process, and the operation of combining steam sterilization and cooling can also be adopted, so that the steam can be thoroughly prevented from being discharged outwards, and the comprehensive sterilization combining the four stages can also be adopted, so that a better disinfection effect can be obtained.
