[0002] Currently, dryers typically rely on internal humidity sensors to detect relative humidity levels to determine whether drying is complete. However, due to the strong correlation between relative humidity and temperature, the measurement results of humidity sensors are often affected by changes in ambient temperature. In particular, when the initial ambient temperature deviates from the standard laboratory temperature, the baseline value of relative humidity will shift, leading to misjudgments in determining the drying status.

As those skilled in the art will know, with the evolution of drying determination systems and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0029] First, this application provides a drying determination method, the executing entity of which is a drying determination device applied to a terminal device. The drying determination method includes: acquiring a first relative humidity value and a first temperature value at a first moment, and acquiring a second relative humidity value and a second temperature value at a second moment, wherein the second moment is the moment after the first moment, with an interval of time between them; determining a first dryness judgment parameter value based on the first relative humidity value, the second relative humidity value, the first temperature value, the second temperature value, and the interval, wherein the first dryness judgment parameter value is used to characterize the actual rate of change of relative humidity with temperature; and determining the drying determination result of the load based on the first dryness judgment parameter value and the second dryness judgment parameter value, wherein the second dryness judgment parameter value is used to characterize the theoretical rate of change of relative humidity with temperature under the condition of the same absolute humidity.

[0030] like Figure 2 The diagram shown is a flowchart of an embodiment of the drying determination method in this application. The drying determination method may include the following steps S201 to S203, as detailed below: Step S201: Obtain the first relative humidity value and the first temperature value at the first moment, and obtain the second relative humidity value and the second temperature value at the second moment, wherein the second moment is the moment after the first moment, which is the time interval between the first moment and the first moment.

[0031] In one specific embodiment, the first and second relative humidity values ​​can be measured by a humidity sensor installed inside the dryer. The humidity sensor can detect and record the relative humidity inside the dryer in real time, which is the ratio between the water vapor content in the air and the maximum amount of water vapor the air can carry, typically expressed as a percentage. Similarly, the first and second temperature values ​​can be measured by a temperature sensor installed inside the dryer. The temperature sensor can detect and record the temperature inside the dryer in real time.

[0032] Furthermore, the interval between the first and second moments can be any length and is not limited here.

[0033] Step S202: Determine the first dryness parameter value based on the first relative humidity value, the second relative humidity value, the first temperature value, the second temperature value, and the interval duration, wherein the first dryness parameter value is used to characterize the actual rate of change of relative humidity with temperature.

[0034] The rate of change of relative humidity is mainly affected by two factors. On the one hand, relative humidity changes with temperature. Assuming the water vapor content in the air remains constant, as the temperature rises, the air can hold more water vapor, meaning the maximum amount of water vapor the air can hold increases, thus the relative humidity decreases. Conversely, when the temperature decreases, the relative humidity increases. On the other hand, if the load is not completely dried, moisture will continue to evaporate from the load, increasing the water vapor content in the dryer, which in turn leads to an increase in the relative humidity value measured by the humidity sensor.

[0035] In one specific embodiment, the first dryness parameter value is used to characterize the rate of change of relative humidity with temperature in actual conditions. If the load is not yet dry in actual conditions, the evaporated moisture will cause a difference between the actual rate of change of humidity and the rate of change of humidity caused by pure temperature. Therefore, the first dryness parameter can help determine whether the load has been dried.

[0036] Step S203: Determine the drying judgment result of the load based on the first drying parameter value and the second drying parameter value, wherein the second drying parameter value is used to characterize the theoretical rate of change of relative humidity with temperature under the condition of the same absolute humidity.

[0037] In one specific embodiment, the drying status of the load can be determined by comparing a first drying parameter value and a second drying parameter value. The second drying parameter value characterizes the theoretical rate of change of relative humidity with temperature under the assumption of the same absolute humidity. Theoretically, if the load has been completely dried, moisture evaporation within the machine stops, causing the absolute humidity to no longer change. At this point, the change in relative humidity is only affected by temperature changes. Therefore, the second drying parameter value reflects the theoretical rate of change of relative humidity, that is, the humidity change caused solely by temperature changes in the absence of moisture evaporation. If the load is not completely dried, the actual rate of change of humidity will differ from the theoretical rate of change because moisture continues to evaporate, causing changes in absolute humidity. By comparing the first and second drying parameter values, it is possible to accurately determine whether the load has been dried.

[0038] In another specific embodiment, the second interference parameter value is a theoretical value, which can be obtained either through real-time calculation or by looking up data in a pre-calculated table containing variables such as different temperatures, relative humidity, and temperature differences. In this case, the table pre-stores theoretical rates of change under multiple different scenarios, and the corresponding second interference parameter value can be located in the table by using the temperature and relative humidity at the first moment, as well as the temperature difference between the second and first moments.

[0039] By following the steps above and comparing the actual rate of change with the theoretical rate of change, we can avoid the misjudgment problem caused by relying solely on humidity sensors. This is especially true in environments where the temperature differs significantly from the initial laboratory temperature, thus improving the accuracy of drying determination results. This not only allows us to better adapt to different environmental conditions but also optimizes the drying process, saves energy, and increases efficiency.

[0040] In one specific implementation, obtaining the first relative humidity value and the first temperature value at a first moment, and obtaining the second relative humidity value and the second temperature value at a second moment, includes: obtaining the third relative humidity value at a third moment; the third moment is a moment before the first moment; determining whether the third relative humidity value is less than or equal to a predetermined humidity value; if the third relative humidity value is less than or equal to the predetermined humidity value, obtaining the first relative humidity value and the first temperature value at the first moment, and obtaining the second relative humidity value and the second temperature value at the second moment.

[0041] In this embodiment, the relative humidity value collected by the sensor can be monitored in real time to determine when to start the drying judgment method. Specifically, steps S201 to S203 are only executed when the real-time relative humidity value is less than or equal to a predetermined humidity value.

[0042] In one specific embodiment, the third moment can be the current moment in the real-time monitoring process. That is, it is determined in real time whether the relative humidity value collected by the sensor is less than or equal to a predetermined humidity value. If it is less than or equal to the predetermined humidity value, then step S201 is executed to collect the first relative humidity value and the first temperature value at the first moment after the third moment. After waiting for the interval, the second relative humidity value and the second temperature value at the second moment are collected. This embodiment ensures that the determination is made when the humidity is close to the predetermined target by delaying the determination, thereby avoiding the resource consumption caused by making the determination in advance before the moisture has completely evaporated.

[0043] In another specific embodiment, if the third relative humidity value is greater than the predetermined humidity value, the next moment after the third moment is determined as the third moment, and the step of acquiring the third relative humidity value at the third moment continues until the third relative humidity value is less than or equal to the predetermined humidity value. That is, if the third relative humidity value is greater than the predetermined humidity value, it indicates that the moisture has not completely evaporated. At this time, the next moment after the third moment can be determined as the third moment, and the third relative humidity value can be continuously monitored to achieve real-time monitoring of the relative humidity value collected by the sensor. When the collected relative humidity value is less than or equal to the predetermined humidity value, step S201 is executed.

[0044] In one specific implementation, determining a first desiccation parameter value based on a first relative humidity value, a second relative humidity value, a first temperature value, a second temperature value, and an interval duration includes: determining a relative humidity change rate based on the first relative humidity value, the second relative humidity value, and the interval duration; determining a temperature change rate based on the first temperature value, the second temperature value, and the interval duration; and determining the ratio of the absolute value of the relative humidity change rate to the temperature change rate as the first desiccation parameter value.

[0045] In this embodiment, the difference between the first and second relative humidities can be calculated and divided by the time interval to obtain the relative humidity change rate. Simultaneously, the difference between the first and second temperature values ​​can be divided by the time interval to obtain the temperature change rate. Finally, the ratio of the absolute value of the relative humidity change rate to the temperature change rate is determined as the first dryness-determination parameter value, i.e., the first dryness-determination parameter value. Determined by the following formula:

[0046] in, The first relative humidity value, This is the second relative humidity value. For the first moment, For the second moment, The first temperature value. This is the second temperature value.

[0047] In one specific implementation, the second dryness-determination parameter value is determined based on the following method: determining the absolute humidity value based on the first temperature value and the first relative humidity value; determining the third relative humidity value based on the second temperature value and the absolute humidity value; and determining the second dryness-determination parameter value based on the first relative humidity value, the third relative humidity value, the first temperature value, and the second temperature value.

[0048] In this embodiment, assuming that the absolute humidity remains constant at the first and second moments, the theoretical third relative humidity value at the second moment is first determined. Then, the theoretical relative humidity change is determined based on the first and third relative humidity values, and the temperature change is determined based on the first and second temperature values. Finally, the theoretical rate of change of relative humidity with temperature is calculated as the second drierness parameter value. Absolute humidity refers to the mass of water vapor contained in a unit volume of air; it is a physical quantity reflecting the moisture content in the air, and its unit is... .

[0049] In one specific implementation, determining a second desiccation parameter value based on a first relative humidity value, a third relative humidity value, a first temperature value, and a second temperature value includes: determining the absolute value of the difference between the first and third relative humidity values ​​as the ideal relative humidity difference; subtracting the first temperature value from the second temperature value to obtain the temperature difference; and determining the ratio of the ideal relative humidity difference to the temperature difference as the second desiccation parameter value.

[0050] In this embodiment, the absolute value of the difference between the first relative humidity and the third relative humidity can be calculated as the ideal relative humidity difference. Simultaneously, the difference between the first temperature value and the second temperature value can also be used as the temperature difference. Finally, the ratio of the ideal relative humidity difference to the temperature difference is determined as the second dryness-determination parameter value, that is, the second dryness-determination parameter value. Determined by the following formula:

[0051] in, This is the third relative humidity value.

[0052] In one specific implementation, determining the absolute humidity value based on a first temperature value and a first relative humidity value includes: determining a first saturated vapor pressure at the first temperature value; determining a first actual vapor pressure based on the first relative humidity value and the first saturated vapor pressure; determining the absolute humidity value based on the first actual vapor pressure; determining a third relative humidity value based on a second temperature value and an absolute humidity value includes: determining a second saturated vapor pressure at the second temperature value; determining a second actual vapor pressure based on the second temperature value and the absolute humidity value; and determining the ratio of the second actual vapor pressure to the second saturated vapor pressure as the third relative humidity value.

[0053] In this embodiment, the absolute humidity value and the relative humidity value can be calculated based on the basic formulas in the field of physical chemistry that describe the relationship between the temperature, pressure, mass and density of a gas.

[0054] Specifically, the first temperature value can be substituted into the Magnus formula (a formula used to describe the relationship between saturated vapor pressure and temperature) to determine the first temperature value. The first saturated water vapor pressure :

[0055] in, It is a natural exponential function, the first saturated vapor pressure The unit is hPa.

[0056] Then, based on the definition of relative humidity (i.e., relative humidity is the ratio of actual water vapor pressure to saturated water vapor pressure in the air), and according to the first relative humidity value... and the first saturated water vapor pressure Determine the first actual water vapor pressure :

[0057] Among them, the first actual water vapor pressure The unit is hPa.

[0058] Then, we can apply the ideal gas law. Based on (where) This refers to gas pressure, measured in Pa. This is the volume of gas, in units of... , This refers to the amount of substance of a gas, expressed in mol. It is the ideal gas constant, with units of J / (mol•K). Let be the thermodynamic temperature (in K), and express the gas volume in terms of gas mass and gas density (because gas volume equals gas mass divided by density). Express the amount of substance in terms of mass and molar mass (because amount of substance equals mass divided by molar mass). Express the ideal gas constant in terms of the gas constant of water vapor and the molar mass of water (because the ideal gas constant equals the gas constant of water vapor multiplied by the molar mass of water). This yields the following formula:

[0059] in, This refers to gas pressure, measured in Pa. This is the density of water vapor, in units of... , The gas constant for water vapor is approximately 461.5 J / (kg•K). Temperature is the thermodynamic temperature, measured in Kelvin (K).

[0060] And because the unit of absolute humidity (AH) is Water vapor density The unit is The above formula can be rewritten as:

[0061] Based on this, and because of the actual water vapor pressure The unit is hPa, while gas pressure The unit is Pa, and the above formula can be further rewritten as:

[0062] In actual calculations, if the measured temperature is in degrees Celsius, you can add 273.15 to the measured temperature to convert it to a temperature in Kelvin.

[0063] Therefore, the first temperature value can be... After unit conversion, it is compared with the first actual water vapor pressure. Substituting these values ​​into the above formula, we can calculate the absolute humidity at the first moment. .

[0064] Under ideal conditions, the absolute humidity from the first moment to the second moment... If it remains constant, then the absolute humidity can be calculated. The second temperature value measured at the second time point Specifically, the second temperature value can be calculated. The second saturated water vapor pressure :

[0065] in, It is a natural exponential function, the second saturated vapor pressure The unit is hPa.

[0066] And, according to absolute humidity Calculate the second temperature value The second actual water vapor pressure :

[0067] Finally, based on the second actual water vapor pressure Second saturated water vapor pressure Calculate the third relative humidity under ideal conditions :

[0068] In one specific implementation, determining the drying determination result of the load based on the first and second drying parameter values ​​includes: determining the ratio of the first and second drying parameter values ​​as a third drying parameter value; determining the drying determination result of the load as a first result when the third drying parameter value is greater than or equal to a predetermined threshold and the duration is greater than or equal to a predetermined duration, wherein the first result indicates that the load has been dried; and determining the drying determination result of the load as a second result when the third drying parameter value is less than the predetermined threshold, or the duration of the third drying parameter value being greater than or equal to the predetermined threshold is less than the predetermined duration, wherein the second result indicates that the load has not been dried.

[0069] In this embodiment, the first interference parameter value The rate of change of relative humidity is calculated based on the actual measured temperature and humidity values, while the second criterion parameter value... This is based on the ideal rate of temperature change under the assumption of constant absolute humidity. The third dryness parameter is... The ratio reflects the actual correlation between the rate of humidity change and the temperature change. When the third drying parameter is close to 1 or greater than or equal to the predetermined threshold α, it indicates that the actual humidity change can be almost entirely explained by the temperature rise effect, that is, the rate of humidity decrease is related to the rate of temperature increase, and no additional moisture evaporation is required. This indicates that moisture evaporation inside the dryer has almost or completely stopped, and there is no longer a source of evaporable moisture inside the load. To further improve the reliability of the judgment result, a threshold for the duration can be set as a predetermined duration. Only when the value of the third drying parameter is greater than or equal to the predetermined threshold, and the duration is greater than or equal to the predetermined duration, is it determined that the load has been dried. Conversely, if there is still moisture evaporation in the load, the rate of humidity change will deviate significantly from the theoretical value, causing the third drying parameter to be lower than the predetermined threshold, or the third drying parameter not to be continuously greater than or equal to the predetermined threshold. In this case, it is determined that the load has not been dried.

[0070] As a specific example, such as Figure 3 As shown, during the drying process, the relative humidity value inside the dryer, measured by a humidity sensor, can be monitored in real time. The next step only begins when the real-time relative humidity value is less than or equal to the predetermined humidity value RH0; otherwise, the relative humidity value continues to be monitored until it is less than or equal to the predetermined humidity value RH0. If the real-time relative humidity value is less than or equal to the predetermined humidity value RH0, the temperature and relative humidity values ​​at the first and second moments are recorded, along with the time difference between the two moments, and the first drying parameter value is calculated accordingly. Second interference parameter value If the third interrogation parameter is... If the load is ≥ the predetermined threshold α and the duration is ≥ the predetermined duration t0, the load is determined to be dry; otherwise, the load is determined to be not dry.

[0071] To better implement the drying determination method in the embodiments of this application, a drying determination device is also provided in the embodiments of this application, such as... Figure 4 As shown, the drying determination device 400 includes: The acquisition module 410 is used to acquire the first relative humidity value and the first temperature value at the first moment, and to acquire the second relative humidity value and the second temperature value at the second moment, wherein the second moment is the moment after the first moment, which is the time interval between the first moment and the first moment. The first determining module 420 is used to determine a first dryness parameter value based on a first relative humidity value, a second relative humidity value, a first temperature value, a second temperature value, and an interval duration, wherein the first dryness parameter value is used to characterize the actual rate of change of relative humidity with temperature. The second determining module 430 is used to determine the drying determination result of the load based on the first drying parameter value and the second drying parameter value, wherein the second drying parameter value is used to characterize the theoretical rate of change of relative humidity with temperature under the condition of the same absolute humidity.

[0072] In this embodiment of the application, by obtaining temperature and relative humidity values ​​at different times, the actual rate of change of relative humidity with temperature is determined, and the ideal rate of change of relative humidity with temperature is obtained under the assumption of the same absolute humidity.
