(1) when disinfection is required, the ultraviolet lamp tube 72 is opened, ultraviolet rays with two wavelengths of 253.7nm and 184.9nm are generated simultaneously (wherein the ultraviolet rays with the wavelength of 253.7nm have a better sterilization effect, and the ultraviolet rays with the wavelength of 184.9nm can convert oxygen in the air into ozone), as shown in fig. 8 and 10, at this time, the control panel 3 is in the first state, the blocking piece 31 of the control panel 3 is covered on the outlet of the first air duct 41 in a sealing manner, the elastic piece 64 is compressed, the first through hole 6311 of the second flow guide seat 63 is covered by the peripheral wall of the upstream section 621 of the flow guide tube, the first flow guide channel 61 and the second flow guide channel 411 are not communicated, the first air duct 41 and the blocking piece 31 together have a double-sealing effect, and the baffle 84 seals the second air duct 71, so as to avoid ozone leakage;

(2) when drying is needed, the sterilizing device 7 is closed, and the heating element 71 is started to heat, so that ozone is decomposed; on the other hand, the tableware is dried and water drops on the surface of the tableware are converted into water vapor;

(3) after the drying is finished or at the end of the drying stage, the driving mechanism 5 and the fan 83 are started, at this time, as shown in fig. 9 and 11, the control panel 4 is driven by the driving mechanism 5 to be turned upwards to a second state, the blocking piece 31 is separated from the outlet of the first air duct 41, the second flow guide seat 63 moves in the opposite direction to the first flow guide seat 62 under the action of the elastic piece 64, and the first through hole 6311 of the second flow guide seat 63 is gradually exposed to communicate the first flow guide channel 61 and the second flow guide channel 411;

in fig. 9 and 11, the direction indicated by the solid arrows is an airflow direction, the direction indicated by the dotted arrows is a water vapor flow direction, the outside air enters the second air duct 81 through the filter screen 85 by the air inlet hood 86 under the action of the fan 83, at this time, the baffle 84 swings with the wind to realize air inlet, the air enters the disinfection chamber 21 through the second flow through hole 23, the air density in the disinfection chamber 21 is different due to the drying process, the hot airflow rises upwards to generate an upward airflow, the airflow drives the water vapor in the disinfection chamber 21 to sequentially enter the first air duct 41 through the first flow through hole 22, then enters the first flow guide channel 61, then enters the second flow guide channel 411 through the first through hole 6311, and finally is discharged into the outside air from the second through hole 6331, and the damp and hot air flow are buffered and condensed due to the fact that the airflow is turned around the exhaust paths of the first flow guide channel 61 and the second flow guide channel 411, finally, the water vapor in the first flow guide channel 61 is condensed and then discharged from the first through hole 6311 and collected into the liquid collecting tank 42, and the water vapor in the second flow guide channel 411 is condensed and finally collected into the liquid collecting tank 42, so that the phenomenon that a lump of gas impacts an operator and the airflow is dispersed into multiple strands of thin flows is avoided, and the risk that the operator is scalded by the water vapor in the exhaust process is reduced;

(4) after the exhaust is finished, the fan 83 is turned off, and the driving mechanism 5 is started again, as shown in fig. 8 and 10, the control panel 4 is driven by the driving mechanism 5 to turn back to the first state, the second diversion seat 63 is driven to squeeze the elastic member 64, and move towards the first diversion seat 62 until the first through hole 6311 of the second diversion seat 63 is covered by the peripheral wall of the upstream section 621 of the diversion pipe again.
