Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

The disinfection cabinet shown in fig. 1 and 2 comprises an inner shell 4 and an outer shell 5 wrapped outside the inner shell, wherein a cavity for disinfection is formed inside the inner shell 4, and a fan 3 capable of exhausting air in the cavity to the outside is arranged between the inner shell and the outer shell; be equipped with the first temperature humidity transducer 2 that is used for detecting temperature and humidity in the cavity on the inner shell, be equipped with the second temperature humidity transducer 1 that is used for detecting outside humidity and temperature on the shell, first temperature humidity transducer, second temperature humidity transducer and stoving work module all are connected with the master controller electricity.

After the drying working module is started, the disinfection cabinet is controlled by the following steps:

step one, a main controller collects an internal temperature value T inside a cavity_{Inner part}And an internal relative humidity value RH of the interior of the chamber_{Inner part}(ii) a Meanwhile, the main controller collects the external temperature value T of the cavity_{Outer cover}External relative humidity value RH of the outside of the chamber_{Outer cover}Entering the step 2;

step two, the main controller is used for controlling the temperature according to the external temperature value T_{Outer cover}And external relative humidity value RH_{Outer cover}Calculating to obtain the absolute humidity H outside the cavity_{Outer cover}Then go to step three, wherein

step three, the main controller judges whether the execution time of the drying program reaches a preset third time t₃If yes, entering the step four, otherwise, staying in the step three;

step four, the master controller starts the fan to enable the fan to start working, and the step five is entered;

step five, the main controller judges the internal temperature value T_{Inner part}And the maximum temperature value T in the preset cavity_maxIf T is_{Inner part}>T_maxEntering a sixth step, otherwise entering a ninth step;

step six, the main controller closes the drying working module and enters step seven;

seventhly, judging the internal temperature value T by the main controller_{Inner part}And the minimum temperature value T in the preset cavity_minIf T is_{Inner part}<T_minEntering the step eight, otherwise, staying in the step seven;

step eight, the main controller controls the drying working module to continue working, and the step nine is entered;

step nine, presetting a first time t₁If the master controller collects the relative humidity value RH of the inner phase_{Inner part}Less than internal relative humidity minimum RH_{For internal min}Entering the step ten, otherwise returning to the step five, wherein

R is a gas constant, R is 8.314J/(mol K), T_maxIs the highest temperature value in the preset cavity,

is at T_maxSaturated vapor pressure of water at temperature, H_{Outer cover}Absolute humidity outside the cavity;

step ten, the main controller closes the drying working module and enters the step eleven;

step twelve, the fan is closed, and the fan stops working.

In this example, t₃Is 5 minutes; the preset first time t₁Is 2 minutes, the second time t₂Was 2 minutes.

The fan starts to work after the drying working module starts to work for 5 minutes, so that the temperature in the cavity is quickly increased, and the drying efficiency is improved; when the temperature in the cavity reaches Tmax, the drying working module is closed, so that the highest temperature in the cavity during drying is limited, and the service life of the disinfection cabinet is prolonged; when the temperature in the cavity is lower than RH within min, the drying working module stops working, so that water vapor can be effectively prevented from being separated out from the air when the temperature in the cavity is reduced after the drying procedure is finished, and no residual water drops in the cavity are kept; after the drying module stops working, the residual heat in the cabinet can continue to dry the tableware, so that the fan continues to work for 2 minutes.
