[0006] 2. Due to the temperature difference in a single area, there are locations with high temperature and locations with low temperature in the area.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0026] Figure 1 The flow chart of the drying control method of the present application is schematically shown. Referring to Figure 1 , the drying control method proposed by the embodiment of the present application specifically comprises steps S1-S4:

[0027] S1, when the drying phase ends, control the moisture removal mechanism to remove moisture to remove the hot and humid air in the drying cavity;

[0028] The phase end described in this embodiment refers to that the whole drying is divided into several phases, and when each phase ends, it is judged; if the requirement is met, the next phase of drying is carried out; if the requirement is not met, the drying is stopped, and the whole drying process is completed.

[0029] In one embodiment, the drying phase is divided in a timing manner. For example, 5 minutes is taken as a phase for drying. Thus, every 5 minutes is taken as a phase for drying, and with the progress of drying, the moisture of the articles in the drying cavity gradually evaporates, so that the humidity in the drying cavity gradually increases.

[0030] And the moisture removal mechanism described in this embodiment includes a moisture removal channel connected to the drying cavity and a fan. With the rotation of the fan, the hot and humid air is removed from the drying cavity along the moisture removal channel.

[0031] S2, obtaining the humidity parameter of the hot and humid air;

[0032] In one embodiment, a humidity sensor is installed at the moisture removal channel for detecting the humidity parameter of the hot and humid air; with the moisture removal assembly removing the hot and humid air, the hot and humid air passes through the humidity sensor, and the humidity sensor detects the humidity parameter of the hot and humid air.

[0033] The humidity parameter includes humidity, and other related quantities that can indirectly show humidity, such as weight change of the articles to be dried, air water content, etc.

[0034] S3, judging whether the change of the humidity parameter of the hot and humid air is gradually flat and the final value is lower than a preset value;

[0035] Obviously, the drying control described in the embodiment needs to judge that two conditions are met:

[0036] 1. whether the humidity parameter change of the hot air is gradually smooth;

[0037] 2. whether the final value of the air humidity parameter is lower than the preset value.

[0038] Wherein, whether the air humidity parameter change is smooth includes:

[0039] Every preset unit time, periodically obtain the humidity value of the hot air;

[0040] Calculate the difference between adjacent humidity values;

[0041] If the difference between adjacent humidity values is less than the fluctuation error, it is determined that the air humidity parameter change is smooth;

[0042] If the difference between adjacent humidity values is greater than or equal to the fluctuation error, the air humidity parameter change has not yet been smooth.

[0043] Specifically, the preset unit time can be 1 min, that is, the air humidity is obtained every 1 min, thereby obtaining h1, h2, h3, etc. Each humidity value can also be the current average humidity obtained by a 5s average detection method to ensure that each humidity value accurately reflects the current humidity state and ensure.

[0044] In one embodiment, taking the collection of three air humidity parameters as an example, three humidity values h1, h2, h3 can be obtained, and the difference between two stages h2-h1=Δh1, h3-h2=Δh2 is calculated, and so on. When the continuous 2 times of humidity difference are both less than the minimum allowable fluctuation error (for example, 2%), it is determined that the air humidity parameter converges.

[0045] In another embodiment, the air humidity parameter change is displayed by the slope change.

[0046] Since the dehumidification mechanism stops during drying, the drying cavity is a closed space except for passive heat dissipation, and the temperature difference in the drying cavity is small. By detecting the fluctuation error, it is judged that the air humidity change is smooth, ensuring that the temperature in the drying cavity has been completed. The temperature in the drying cavity has been completed, and the articles to be dried have been initially dried or even completed, thereby ensuring the drying effect and reducing the drying damage.

[0047] Wherein, before the drying starts, the initial humidity value is obtained, and the initial humidity value is taken as the preset value.

[0048] The humidity initial value is the humidity initial value at the exhaust channel, which is obtained by detecting with a humidity sensor. Since drying has not started at this time, the humidity initial value at this time is equivalent to the ambient humidity. The ambient humidity is used as a preset value, and a humidity regression algorithm is used to prevent over-drying of the articles to be dried and to prevent damage to the articles to be dried. Generally, the preset value is 40%, so if the final humidity value is greater than 40%, the next stage of drying is started, and if it is less than 40%, the drying is stopped.

[0049] The final value is the last humidity collected in the periodically obtained humidity values of the hot and humid air.

[0050] S4, if the humidity parameter change of the hot and humid air is not yet smooth, continue drying and exhaust, until the humidity parameter change of the hot and humid air is smooth;

[0051] If the humidity parameter change of the hot and humid air is smooth and the final value is less than the preset value, stop drying and exhaust;

[0052] If the humidity parameter change of the hot and humid air is smooth and the final value is greater than or equal to the preset value, stop exhaust and start the next stage of drying;

[0053] When the humidity parameter change of the hot and humid air is smooth, it can be considered that the heating of the drying cavity is complete, and the preliminary drying of the articles to be heated is complete; if the final value is less than the preset value, it represents that the entire drying process is complete, and the entire process can be stopped; if the final value is greater than or equal to the preset value, it represents that the drying progress of each article to be heated is the same, but the entire drying has not yet been completed.

[0054] In one embodiment, when the next drying stage is completed, the process of judging whether the humidity parameter change of the hot and humid air is smooth can be omitted, and only whether the final value is less than the preset value is judged, to speed up the judgment and prevent overheating.

[0055] The drying control method provided by the embodiments of the present application uses a humidity regression algorithm to automatically identify the state of the articles to be dried, intelligently divides the drying into stages, and ensures the drying effect while reducing drying damage.

[0056] In one specific embodiment of the present application, the following process is included:

[0057] 1. Record the initial humidity;

[0058] 2. Control the heating port to be opened and start the drying assembly to perform timed drying;

[0059] 3. When the drying stage is completed, start the exhaust assembly and collect the humidity parameter,

[0060] 4. Judge whether the area humidity is regressed;

[0061] 5. If the regression is completed, the drying assembly and the heating port are closed, and if the regression is not completed, the moisture removal assembly is closed and the next stage of drying is started.
