When humidity sensor 7 monitors that the humidity is great in disinfection chamber 21, but automatic start heating pipe 311 and ventilation unit 4, when detecting that the humidity drops to predetermined minimum in disinfection chamber 21, can close heating pipe 311 and ventilation unit 4, keep dry clean environment in the assurance cabinet, avoid bacterial growing.
The working principle of the embodiment is as follows:
(1) when drying is needed, the heating pipe 311 and the centrifugal fan 42 are turned on, as shown in fig. 12, the direction indicated by the solid line arrow is an airflow direction, the heating element 31 is heated to generate heat, due to a chimney effect, the heating causes a difference in air density in the disinfection chamber 21, the hot airflow rises upwards to generate an upward airflow, and under the action of the centrifugal fan 42, the airflow carries the water vapor in the disinfection chamber 21 to enter the first air duct 41 through the first flow through hole 22 in sequence, the water vapor passing through the first air duct 41 is condensed through each condensing sheet 56, water drops drop from the second flow through hole 561 to the water deflector 57 (the direction indicated by the dotted line arrow is the moisture direction), and then are collected into the water storage chamber 611 through the water outlet 51 and the water inlet pipe 62, and the residual dry airflow passes through the air vent 571 and then returns to the disinfection chamber 21 along the first air duct 41 through the second flow through hole 23, blowing the heat to the heating pipe 311, further quickly diffusing the heat generated by heating to each corner of the disinfection cavity 21, realizing sufficient internal circulation in the disinfection cavity 21, and finally ensuring that the temperature field at each corner is uniform and the tableware drying effect is good;
(2) after drying, the heating pipe 311 can be closed to exhaust steam, when the humidity sensor 7 detects that the humidity in the disinfection chamber 21 drops to a preset minimum value, it indicates that the water vapor in the disinfection chamber 21 is completely exhausted, and then the centrifugal fan 42 can be closed, so that a dry and clean environment in the cabinet is ensured, and bacteria are prevented from breeding;
(3) the principle of water cooling is the same as that of example 1.
