FIG. 2 is a schematic view of the internal structure of the disinfection cabinet according to the embodiment of the present invention.
FIG. 3 is a flowchart of a drying control method for the disinfection cabinet according to an embodiment of the present invention.
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 cavityInner partAnd an internal relative humidity value RH of the interior of the chamberInner part(ii) a Meanwhile, the main controller collects the external temperature value T of the cavityOuter coverExternal relative humidity value RH of the outside of the chamberOuter coverEntering the step 2;
step two, the main controller is used for controlling the temperature according to the external temperature value TOuter coverAnd external relative humidity value RHOuter coverCalculating to obtain the absolute humidity H outside the cavityOuter coverThen go to step three, wherein
Wherein P isOutside TIs at TOuter coverSaturated vapor pressure of water at temperature, R being gas constant, R-8.314J/(mol K);
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 TInner partAnd the maximum temperature value T in the preset cavitymaxIf T isInner part>TmaxEntering 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 controllerInner partAnd the minimum temperature value T in the preset cavityminIf T isInner part<TminEntering 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 phaseInner partLess than internal relative humidity minimum RHFor internal minEntering the step ten, otherwise returning to the step five, wherein
R is a gas constant, R is 8.314J/(mol K), TmaxIs the highest temperature value in the preset cavity,
is at TmaxSaturated vapor pressure of water at temperature, HOuter coverAbsolute humidity outside the cavity;
step ten, the main controller closes the drying working module and enters the step eleven;
step eleven, if the drying working module finishes working and reaches the preset second time t2Entering step 12, otherwise, staying at step 11;
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.
