[0021] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of this disclosure. However, it will be apparent to those skilled in the art that this disclosure can be practiced without one or at least three of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with this disclosure.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0023] Exemplary embodiments according to this disclosure will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that this disclosure will be thorough and complete, and that the concept of these exemplary embodiments will be fully conveyed to those skilled in the art.

[0024] Currently, existing household appliances typically use the warm airflow generated by heating modules to dry cleaned objects. However, existing household appliances cannot accurately control the drying temperature, which can easily damage the objects. Especially during the rapid drying stage, if the temperature inside the drying chamber rises rapidly, the damage to the objects will be even greater.

[0025] This disclosure provides a household appliance, including a receiving cavity for accommodating objects to be dried, a drying module 10, and a controller.

[0026] The controller is used in the object drying method for household appliances provided in this embodiment of the disclosure. The controller can be implemented using various application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), microcontrollers, microprocessors, or other electronic components.

[0027] As shown in Figure 1, the drying module 10 includes a suction module 101, a dehumidification module 102, and a heating module 103. The suction module 101 is used to suction gas from the receiving cavity to form a humidified circulating airflow. The dehumidification module 102 is located downstream of the suction module 101, and at least a portion of the dehumidification module 102 is used to dehumidify the humidified circulating airflow. The heating module 103 is used to heat and dry at least another portion of the dehumidification module 102. In some embodiments, the air outlet of the receiving cavity, portions of the suction module 101 and the dehumidification module 102, and the air inlet of the receiving cavity are sequentially connected to form a circulating air duct. A temperature and humidity detection component 104 is provided in the circulating air duct. The temperature and humidity detection component 104 can be located between the air outlet of the receiving cavity and the air inlet of the suction module 101; or, it can be located between the air outlet of the receiving cavity and the air inlet of the dehumidification module 102, for example, on the air duct between the air outlet of the suction module 101 and the air inlet of the dehumidification module 102.

[0028] The suction module 101 includes a circulating fan. The air inlet of the circulating fan is connected to the air outlet of the receiving cavity. The circulating fan draws in the humid gas in the receiving cavity, providing power for the formation of a humid circulating airflow in the circulating air duct, which is beneficial to the circulation of airflow.

[0029] The dehumidification module 102 includes a rotating disk and a drive assembly. The rotating disk is located on the circulating air duct, and the drive assembly may include a motor that drives the rotating disk to rotate. The rotating disk may be made of a material with good moisture absorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X type) molecular sieve.

[0030] The heating module 103 includes a regeneration air duct and a heater disposed on the regeneration air duct, the heater being located above at least another portion of the turntable. The heater includes multiple heating tubes connected end-to-end, spaced apart along the radial direction of a fan shape; the extension direction of the heating tubes is perpendicular or nearly perpendicular to the radial direction of the fan shape. The heating tubes are S-shaped, allowing for a longer distribution of the heating tubes within the heater housing area, thereby increasing the contact area with the regeneration airflow within the regeneration air duct and thus improving the efficiency of heat exchange with the regeneration airflow.

[0031] The heater heats the dried regeneration airflow in the regeneration duct. The heated regeneration airflow passes through a turntable, heating and dehydrating the portion of the turntable located below the heater. This ensures that this portion of the turntable reaches a temperature close to that of the heater. As the drive assembly rotates the turntable, this portion rotates onto the circulation channel. Here, this portion of the turntable can absorb moisture from the humid circulating airflow in the receiving cavity, making the humid circulating airflow dry. It can also heat the humid circulating airflow. In other words, this portion of the turntable can both absorb moisture from the humid circulating airflow and transfer some of the heat from the heater to the humid circulating airflow, thus making the humid circulating airflow dry and at a certain temperature. It also ensures that the humid circulating airflow changes relatively steadily after drying and heating, without a temperature surge. Consequently, the gas flowing out of the receiving cavity, i.e., the humid circulating airflow, also changes relatively steadily without a temperature surge. Then, this circulating airflow flows into the receiving cavity through the air inlet, making full contact with the object to be dried in the receiving cavity to dry it. As the turntable rotates, this part of the turntable, after drying and heating the wet circulating airflow, rotates back to the bottom of the heating module 103, so that the dried regenerated airflow heated by the heating module 103 can reheat and dry this part of the turntable, thus maintaining the reusability of the turntable.

[0032] It is understandable that the regeneration air duct and the circulation air duct are two independent air ducts to minimize the crosstalk between the humid circulation airflow and the regeneration airflow. This is beneficial for the turntable to continuously adsorb moisture and dehydrate and dry during rotation, so that the turntable always has good water absorption capacity, thereby improving the efficiency and effect of moisture absorption.

[0033] The temperature and humidity detection component 104 may be a temperature and humidity sensor. In some implementations, the temperature and humidity detection component 104 is located in the air duct between the air outlet of the receiving cavity and the air inlet of the circulating fan. In other implementations, the temperature and humidity detection component 104 is located in the air duct between the air outlet of the circulating fan and the air inlet of the dehumidification module 102.

[0034] By placing the temperature and humidity detection component 104 in the air duct between the air outlet of the receiving cavity and the air inlet of the circulating fan, or between the air outlet of the circulating fan and the air inlet of the dehumidification module 102, it is possible to effectively detect the temperature and humidity of the humid circulating airflow flowing out of the receiving cavity to obtain more accurate temperature and humidity values ​​within the receiving cavity, and it also facilitates the installation of the temperature and humidity detection unit. In addition, it greatly reduces the number of detection components, simplifies the structure, and reduces costs.

[0035] In addition to the aforementioned components, the household appliance may also include a motor for driving the rotation of the receiving cavity, as well as water inlet and outlet components, to achieve the function of washing and spin-drying objects, thereby achieving the purpose of washing and drying in one.

[0036] The method for drying objects using household appliances is described in detail below. As shown in Figure 2, in some embodiments, the method includes steps S202 to S202.

[0037] Step S201: Obtain the weight of the object to be dried, the real-time temperature value of the humidified airflow detected by the temperature and humidity detection component, and the first real-time humidity value.

[0038] The object to be dried can be clothing or other items; this embodiment does not strictly limit the object to be dried. The weight of the object to be dried can be obtained by the motor of a household appliance driving the receiving cavity to rotate at a preset speed for a certain period of time. In some embodiments, during the rotation of the receiving cavity, the eccentricity of the receiving cavity is measured by a vibration sensor, an acceleration sensor, etc., and then the weight of the object to be dried is determined by a preset correspondence between the rotation speed, eccentricity, and the weight of the object to be dried, thereby obtaining the weight of the dried object. The preset correspondence between the rotation speed, eccentricity, and the weight of the object to be dried can be a mathematical function, a correspondence table, a correspondence curve, etc., and this embodiment does not impose specific limitations. For example, when the preset correspondence between the rotation speed, eccentricity, and the weight of the object to be dried is a correspondence table, the rows of the table can be the preset rotation speed, the columns can be the eccentricity, and each cell corresponds to the weight of the object to be dried; the weight of the dried object can be obtained by looking up the table.

[0039] Of course, the weight of the object to be dried can also be obtained in other ways, such as by adding a weight sensor. This disclosure does not strictly limit the method of obtaining the weight of the object to be dried.

[0040] The real-time temperature and humidity values ​​of the humid circulating airflow are close to those of the real-time temperature and humidity values ​​inside the containment cavity, so the real-time temperature and humidity values ​​detected by the temperature and humidity detection component can be used as the real-time temperature and humidity values ​​inside the containment cavity.

[0041] Step S202: Based on the weight of the object to be dried, the real-time temperature value, and the first real-time humidity value, control the working status of the heating module, the suction module, and the dehumidification module.

[0042] In this embodiment of the present disclosure, the working state of the heating module, the suction module and the dehumidification module is controlled according to the weight of the object to be dried, the real-time temperature value detected by the temperature and humidity detection component and the first real-time humidity value. For example, the heating module, the suction module and the dehumidification module are controlled to stop working, and the power of the heating module is adjusted, so as to accurately control the drying temperature in the receiving cavity to avoid damage to the object to be dried in the receiving cavity.

[0043] In addition, this home appliance only requires one temperature and humidity detection component, which greatly reduces the number of detection components, simplifies the structure, and reduces costs.

[0044] In one embodiment of this disclosure, the operating states of the heating module, the suction module, and the dehumidification module are controlled based on the weight of the object to be dried, the real-time temperature value, and the first real-time humidity value, including:

[0045] A first drying threshold is determined based on the weight of the object to be dried;

[0046] Based on the real-time temperature value and the first real-time humidity value, the real-time moisture content of the wet circulating airflow flowing out of the containment cavity is determined.

[0047] Determine whether the first dryness condition is met based on the real-time moisture content and the first dryness threshold.

[0048] When the first dryness condition is met, the working state of the heating module is controlled to stop working, and the first humidity value currently detected by the temperature and humidity detection component, the second humidity value detected by the temperature and humidity detection component after the heating module stops working for a preset time, and the preset second dryness threshold are obtained.

[0049] Based on the first humidity value, the second humidity value, and the second dryness threshold, it is determined whether the second dryness condition is met. When the second dryness condition is met, the working state of both the suction module and the dehumidification module is stopped.

[0050] In this embodiment of the disclosure, a first drying threshold is first determined based on the weight of the object to be dried. There is a corresponding relationship between the first drying threshold and the weight of the object to be dried. The first drying threshold can be determined based on this correspondence, which can be a mathematical function, a correspondence table, a correspondence curve, etc., and this embodiment of the disclosure does not impose specific limitations.

[0051] In some embodiments, the first drying threshold can be obtained by looking up a table. In some embodiments, different tables corresponding to the weights of objects to be dried and the first drying threshold can be pre-set. For example, the table can be a 1×n table, where the columns represent the weights of each object to be dried, the rows represent the first drying thresholds, and each cell corresponds to the specific data of the first drying threshold. Then, based on the obtained weights of the objects to be dried, the corresponding first drying threshold can be found by looking up the table, thereby reducing the computational requirements of the controller.

[0052] In other embodiments, the first drying threshold can be calculated using a mathematical function relationship based on the weight of the object to be dried. For example, a mathematical function relationship between the weight of the object to be dried and the first drying threshold can be established in advance based on the weight of different objects to be dried and the corresponding first drying threshold. The mathematical function relationship can be a linear function, a polynomial function, etc. Taking a cubic polynomial as an example, the cubic polynomial between the weight of the object to be dried and the first drying threshold is: f(x) = p1*x^3 + p2*x^2 + p3*x + p4; where f(x) represents the first drying threshold, x represents the weight of the object to be dried, p1 = 0.06667, p2 = -1.5, p3 = 2.433, and p4 = 67. Substituting the obtained weight of the object to be dried into this cubic polynomial yields the corresponding first drying threshold.

[0053] Then, based on the real-time temperature value and the first real-time humidity value, the real-time moisture content of the humidified circulating airflow out of the containment cavity is determined. There is a corresponding relationship between the real-time moisture content and the real-time temperature and humidity values. The real-time moisture content can be determined based on this correspondence, which can be a mathematical function, a correspondence table, a correspondence curve, etc., and this embodiment does not impose specific limitations.

[0054] In some embodiments, real-time humidity content can be obtained by looking up a table. In some embodiments, different correspondence tables between real-time temperature values, real-time humidity values, and real-time humidity content can be preset, and then the corresponding real-time humidity content can be found by looking up the table using the measured real-time temperature value and the first real-time humidity value, thereby reducing the computational requirements of the controller.

[0055] In other embodiments, the real-time moisture content can be calculated using a mathematical function relationship based on the real-time temperature value and a first real-time humidity value. In practical applications, the real-time temperature is always greater than 0°C. For example, the saturated water vapor partial pressure is calculated using the Goff-Gratch equation based on the real-time temperature value, and then the real-time moisture content is calculated based on the saturated water vapor partial pressure and the first real-time humidity value. The calculation process is as follows:

[0056] lgPs=-7.90298*(373.16 / (T+273.15)-1)+5.02808*log10(373.16 / (T+273.15))-1.3816*10^(-7)*(10^(11.344* (1-(T+273.15) / 373.16))-1)+8.1328*10^(-3)*(10^(-3.49149*(373.16 / (T+273.15)-1))-1)+log10(1013.246);

[0057] Ps = 10^lgPs;

[0058] D = 622φPs / (P'-φPs);

[0059] Where T is the real-time temperature value, Ps is the saturated water vapor partial pressure at temperature T, lgPs is the logarithm of the saturated water vapor partial pressure Ps to the base 10, φ is the first real-time humidity value, D is the real-time moisture content, and P' is the reference atmospheric pressure, taken as 102000 Pa (Pascal).

[0060] After determining the real-time moisture content, the drying threshold is determined based on the determined real-time moisture content and the first drying threshold. That is, the first drying condition is determined based on the real-time moisture content and the first drying threshold.

[0061] In one implementation, determining whether the first drying condition is met based on the real-time moisture content and the first drying threshold includes: if the real-time moisture content is less than or equal to the first drying threshold, then it is determined that the first drying condition is met; if the real-time moisture content is greater than the first drying threshold, then it is determined that the first drying condition is not met.

[0062] If the first drying condition is not met, the real-time moisture content of the humidified airflow is high, and the heating module continues to operate. If the first drying condition is met, the real-time moisture content of the humidified airflow is low, meaning the moisture content of the object to be dried is low, and the heating module stops heating. For example, assuming the first drying threshold is 80 g / kg, if the real-time moisture content is 60 g / kg, the heating module stops operating.

[0063] By using real-time moisture content and a first drying threshold for drying determination, the results show high accuracy across different batches of this household appliance, thus improving the applicability of the drying determination and reducing errors. Furthermore, by controlling the heating module to stop working during the drying process, damage to clothing caused by a rapid temperature increase during the quick-drying phase can be avoided. This also allows for more precise control of the heating module's operating time, ensuring both effective drying and preventing energy waste.

[0064] Furthermore, a first humidity value detected by the temperature and humidity detection component when the heating module stops working, and a second humidity value detected by the temperature and humidity detection component after a preset time period since the heating module stopped working are obtained. The first humidity value refers to the real-time humidity value when the heating module stops working, and the second humidity value refers to the real-time humidity value after the preset time period since the heating module stopped working. Based on the obtained first and second humidity values ​​and a preset second desiccation threshold, a second desiccation assessment is performed. The second desiccation threshold and the preset time period can be set by the operator according to actual conditions; this embodiment does not impose strict requirements. In some embodiments, the second desiccation threshold is a positive number, and the preset time period is 5 minutes.

[0065] After the heating module stops working, meaning only the suction module and dehumidification module are used to dry the object, a second drying test is performed to determine if the object is completely dry, thus controlling the operating state of the suction module and dehumidification module. In some embodiments, based on the acquired first humidity value, second humidity value, and a preset second drying threshold, it is determined whether the second drying condition is met. When the second drying condition is met, both the suction module and dehumidification module are controlled to stop working; when the second drying condition is not met, both the suction module and dehumidification module are controlled to continue working.

[0066] In one embodiment, determining whether the second dryness condition is met based on a first humidity value, a second humidity value, and a second dryness threshold includes: calculating the difference between the first humidity value and the second humidity value; if the difference is greater than or equal to the second dryness threshold, then the second dryness condition is determined to be met; if the difference is less than the second dryness threshold, then the second dryness condition is determined not to be met.

[0067] In this embodiment, the difference between a first humidity value and a second humidity value is calculated. The difference is calculated as: first humidity value - second humidity value. This difference can be positive or negative. Specifically, the second humidity value after a preset time since the heating module stopped working may be less than, equal to, or greater than the first humidity value at the time the heating module stopped working. Less than indicates a decrease in humidity after the preset time; equal to indicates that the humidity remains constant after the preset time; and greater than indicates an increase in humidity after the preset time. For example, if the first humidity value is 60 g / kg and the second humidity value is 40 g / kg, then the difference between the first and second humidity values ​​is 20 g / kg; if the first humidity value is 60 g / kg and the second humidity value is 80 g / kg, then the difference between the first and second humidity values ​​is -20 g / kg. Further, it is determined whether the difference is greater than or equal to a second desiccation threshold.

[0068] If the difference is greater than or equal to the second drying threshold, it means that the humidity has decreased significantly since the heating module stopped working after a preset time, indicating that the object to be dried has been completely dried. For example, assuming the second drying threshold is 15 g / kg, if the first humidity value is 60 g / kg and the second humidity value is 40 g / kg, then the difference between the first and second humidity values ​​is 20 g / kg. This difference is greater than the second drying threshold, thus satisfying the second drying condition, indicating that the object to be dried has been completely dried. In this case, the suction module and dehumidification module are stopped, completing the drying process.

[0069] If the difference is less than the second drying threshold and the difference is positive, it means that the humidity has decreased slightly after the heating module has stopped working for a preset time compared to when the heating module stopped working, and the decrease is not significant. The object to be dried may not be completely dry. For example, assuming the second drying threshold is 15g / kg, if the first humidity value is 50g / kg and the second humidity value is 40g / kg, then the difference between the first humidity value and the second humidity value is 10g / kg. The difference is less than the second drying threshold and is positive, so the second drying condition is not met, indicating that the object to be dried may not be completely dry, and the suction module and dehumidification module still need to continue working.

[0070] If the difference is less than the second drying threshold and is negative, it means that the humidity has increased since the heating module stopped working for a preset time, and the object to be dried has not been dried. For example, assuming the second drying threshold is 15g / kg, if the first humidity value is 50g / kg and the second humidity value is 70g / kg, then the difference between the first and second humidity values ​​is -20g / kg. Since the difference is less than the second drying threshold and is negative, the second drying condition is not met, meaning the object to be dried has not been dried, and the suction module and dehumidification module still need to continue working.

[0071] In this embodiment of the present disclosure, the re-drying judgment can accurately control the working time of the suction module and the dehumidification module, that is, it can accurately control the drying end time, thereby ensuring the drying effect and improving the accuracy of the control of the overall drying time, saving resources.

[0072] In one embodiment of this disclosure, the method further includes:

[0073] When the second drying condition is not met, the heating module is controlled to work, and the third drying condition is determined based on the second real-time humidity value and the first humidity value detected by the temperature and humidity detection component.

[0074] When the third dryness condition is met, the heating module, suction module, and dehumidification module all stop working; when the third dryness condition is not met, the heating module, suction module, and dehumidification module continue to work.

[0075] In this embodiment, when the second drying condition is not met—that is, after a preset time since the heating module stopped working, the humidity decreases, but not significantly, compared to when the heating module stopped working—or the humidity rebounds after a preset time since the heating module stopped working, the heating module is activated for drying. Then, a second real-time humidity value is detected by a temperature and humidity detection component. Drying is then determined based on the second real-time humidity value and the first humidity value used for determining dryness. In other words, the third drying condition is determined based on the second real-time humidity value and the first humidity value to determine whether the suction module and dehumidification module have stopped working. It is understood that the second real-time humidity value here refers to the real-time humidity value when the second drying condition is not met and the heating module is controlled to operate.

[0076] In one embodiment, determining whether a third dryness condition is met based on a second real-time humidity value and a first humidity value detected by a temperature and humidity detection component includes: if the second real-time humidity value is less than or equal to the first humidity value, then the third dryness condition is determined to be met; if the second real-time humidity value is greater than the first humidity value, then the third dryness condition is determined not to be met.

[0077] If the third drying condition is met, the heating module, suction module, and dehumidification module will all stop working; if not, they will continue working until the third drying condition is met. For example, assuming the first humidity value is 40 g / kg, if the second real-time humidity value is 35 g / kg, then the suction module and dehumidification module will stop working, which means the drying process will end.

[0078] In this embodiment of the present disclosure, when the second drying condition is not met, drying continues, and the second real-time humidity value is compared with the first humidity value to determine whether the third drying condition is met. When the third drying condition is met, the heating module, suction module and dehumidification module are stopped from working. This allows for more accurate control of drying, thereby ensuring that the object to be dried is completely dried and improving the drying effect.

[0079] As a refinement and extension of the above embodiments, this disclosure provides another method for drying objects from household appliances. As shown in FIG3, the method includes:

[0080] Step S301: Obtain the weight of the object to be dried, the real-time temperature value of the humidified airflow detected by the temperature and humidity detection component, and the first real-time humidity value.

[0081] Step S302: Control the operation of the heating module, suction module and dehumidification module to dry the object to be dried.

[0082] Step S303: Based on the real-time temperature value, adjust the power of the heating module to keep the temperature of the humid circulating airflow within the target temperature range.

[0083] Step S304: Based on the weight of the object to be dried, the real-time temperature value, and the first real-time humidity value, control the working status of the heating module, the suction module, and the dehumidification module.

[0084] Steps S301 and S304 are the same as or similar to steps S201 and S202 in the above embodiment, and will not be described again here.

[0085] In this embodiment, the heating module, suction module, and dehumidification module are controlled to begin drying the object to be dried within the receiving cavity. The power of the heating module is adjusted based on the real-time temperature value of the humidified circulating airflow detected by the temperature and humidity detection component, so that the temperature value of the humidified circulating airflow is maintained within the target temperature range.

[0086] The target temperature range can be set by the operator, and this embodiment does not impose strict limitations. In specific applications, the target temperature range should not be set too high. For example, the target temperature range for the humidified circulating airflow can be set to 80°C-86°C to avoid damage to the objects to be dried due to high temperatures.

[0087] It should be noted that the temperature of the humidified circulating airflow is similar to the temperature inside the containment cavity, therefore the temperature of the humidified circulating airflow can be considered equivalent to the temperature inside the containment cavity.

[0088] In this embodiment of the invention, by adjusting the power of the heating module, the temperature of the humidified circulating airflow is maintained within the target temperature range, which can accurately control the drying temperature in the cavity, prevent the temperature in the cavity from rising sharply, and avoid damage to the objects to be dried in the cavity.

[0089] In one embodiment of this disclosure, adjusting the power of the heating module based on real-time temperature values ​​to maintain the temperature of the humidified circulating airflow within a target temperature range includes:

[0090] Based on the different temperature control ranges to which the real-time temperature value belongs, the power of the heating module is adjusted sequentially according to multiple temperature control stages. Each temperature control range corresponds to a temperature control stage. The upper limit of multiple temperature control ranges increases sequentially, and the power of the heating module decreases sequentially in multiple temperature control stages. In the last temperature control stage, the temperature value of the humidified circulating airflow is adjusted according to the PID algorithm to keep the temperature value of the humidified circulating airflow within the target temperature range.

[0091] In this embodiment of the disclosure, multiple different temperature control intervals are preset. These multiple temperature control intervals are used to compare with the real-time temperature value to determine the current temperature of the cavity, thereby adjusting the power of the heating module in multiple temperature control stages in sequence.

[0092] In this embodiment, the upper limits of multiple temperature control zones increase sequentially. The number of temperature control zones and the upper and lower limits of the zones can be set by the staff according to the actual situation. This embodiment does not impose strict limitations.

[0093] For example, taking four pre-set temperature control intervals as an example, the four temperature control intervals are [0, 28℃), [28℃, 40℃], (40℃, target_T-3℃], and (target_T-3℃, target_T+3℃]. The value of target_T ranges from 70℃ to 90℃, and the specific value can be set by the operator according to the target temperature range. This embodiment of the disclosure does not impose strict limitations. For example, if the target temperature range of the humidified circulating airflow is 80℃-86℃, then target_T can be 83℃.

[0094] Each temperature control zone corresponds to a temperature control stage. The power of the heating modules decreases sequentially across multiple temperature control stages. In other words, as the real-time temperature increases, the power of the heating modules is reduced sequentially according to the temperature control stage to prevent excessively high drying temperatures. Furthermore, in the final temperature control stage, a PID algorithm is used to adjust the temperature of the humidified circulating airflow to maintain it within the target temperature range. This ensures accurate control of the drying temperature within the drying chamber, preventing damage to the objects inside. The final temperature control stage can be the one with the lowest power output from the corresponding heating module.

[0095] In one embodiment of this disclosure, for a temperature control stage, adjusting the power of the heating module according to the temperature control range to which the real-time temperature value belongs includes:

[0096] Obtain the target average power value of the heating module corresponding to the current temperature control range;

[0097] Control the heating module to turn on periodically, and adjust the on-time of the heating module in the cycle so that the average power of the heating module reaches the target average power value.

[0098] In practical applications, the heating module can be turned on periodically. Within a cycle, the heating module is turned on for a period of time and then turned off for a period of time. In other words, the heating module is turned on intermittently, not continuously. The duration of the cycle is the sum of the on and off times of the heating module within that cycle.

[0099] The average power of the heating module is the ratio of the duration the heating module is on to the duration of the cycle, multiplied by the rated power of the heating module. The specific formula is as follows:

[0100]

[0101] in, P represents the average power value of the heating module, t1 represents the duration the heating module is on within one cycle, t represents the duration of one cycle, and P... t This refers to the rated power of the heating module. For example, the rated power P of the heating module... t Given 2000W, t = 60s, and t1 = 30s, then...

[0102] Each temperature control zone has a corresponding preset average power value for the heating module, which can be set by the operator. For example, continuing with the above example of the four temperature control zones, the preset average power value of the heating module corresponding to [0, 28℃] is 100% of the rated power; the preset average power value of the heating module corresponding to [28℃, 40℃] is 82% of the rated power; the preset average power value of the heating module corresponding to [40℃, target_T-3℃] is 72% of the rated power; and the preset average power value of the heating module corresponding to [target_T-3℃, target_T+3℃] is less than or equal to 75% of the rated power.

[0103] By identifying the temperature control range to which the real-time temperature value belongs, the preset average power value of the corresponding heating module is found and used as the target average power value. For example, if the real-time temperature value is 35℃, then the target average power value of the heating module is 82% of the rated power.

[0104] Furthermore, the heating module is controlled to turn on periodically, and the on-time of the heating module in each cycle is adjusted so that the average power of the heating module reaches the target average power value.

[0105] By adjusting the on-time of the heating module in each cycle, the average power of the heating module is changed to achieve the target average power value. As the real-time temperature increases, the temperature control range changes accordingly, and the target average power value achieved by the heating module also changes. In some embodiments, if the real-time temperature is low, the heating module will be on for a longer period in one cycle, or even remain on continuously for one cycle, resulting in a higher target average power value and continued temperature rise. Conversely, when the real-time temperature is high, the on-time of the heating module is shortened in one cycle, resulting in a lower target average power value and slowing down the rate of temperature increase, preventing excessively rapid heating.

[0106] Continuing with the example of the four temperature control ranges above, if the real-time temperature is 25℃, the heating module is kept on throughout one cycle, ensuring that the average power of the heating module reaches the target average power value, i.e., the rated power, thus causing the real-time temperature to continue to rise. When the real-time temperature is in the 28℃-40℃ range, the on-time of the heating module within one cycle is shortened, ensuring that the average power of the heating module reaches the target average power value, i.e., 82% of the rated power, thus causing the real-time temperature to continue to rise. When the real-time temperature is in the 40℃-target_T-3℃ range, the on-time of the heating module within one cycle is further shortened, ensuring that the average power of the heating module reaches the target average power value, i.e., 72% of the rated power, as the real-time temperature continues to rise. When the real-time temperature value is in the range of target_T-3℃-target_T+3℃, it is necessary to continuously adjust the on-time of the heating module within one cycle so that the target average power achieved by the heating module is less than or equal to 75% of the rated power. The heating module can be controlled by PID algorithm to keep the real-time temperature within the target temperature range, thereby achieving the purpose of keeping the temperature of the containment cavity within the target temperature range.

[0107] In this embodiment, by controlling the heating module to periodically turn on and adjusting the on-time of the heating module in each cycle, the average power of the heating module reaches the target average power value, thereby achieving a better heating effect and avoiding damage to the objects to be dried due to excessive temperature. Furthermore, the PID algorithm controls the temperature of the humidified circulating air flowing out of the container to remain within the target temperature range, thus maintaining the temperature of the container cavity within the target temperature range. This improves the accuracy of drying temperature control and prevents a rapid rise in temperature within the container cavity, thereby avoiding damage to the objects to be dried inside.

[0108] In one embodiment of this disclosure, the method further includes: if the real-time temperature value is greater than the maximum value of the target temperature range, then controlling the heating module to stop working.

[0109] For example, if the target temperature range is [80℃, 86℃], and the real-time temperature is 87℃, then the heating module has malfunctioned. Therefore, the heating module needs to be stopped to avoid damage to the object to be dried due to excessive temperature.

[0110] Furthermore, when the real-time temperature value exceeds the maximum value of the target temperature range, alarms and other prompts can be issued to alert the user of any drying abnormalities.

[0111] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution.
