[0030] Exemplary embodiments according to the present invention 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 the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0031] Firstly, such as Figure 1 As shown, this utility model embodiment provides a drying module, including:

[0032] The suction module 10 is used to suction the gas in the receiving cavity to form a wet circulating airflow. The receiving cavity is used to hold the object to be dried.

[0033] The dehumidification module 20 is located downstream of the suction module 10 and is at least partially used to dehumidify the humidified circulating airflow.

[0034] A heating module 30 is disposed adjacent to a dehumidifying module 20 and is used to heat and dry at least another portion of the dehumidifying module 20.

[0035] The temperature and humidity detection component 40 is installed on the air duct between the air outlet of the receiving cavity and the air inlet of the dehumidification module 20, and is used to detect the real-time temperature and humidity values ​​of the humidified circulating airflow.

[0036] The suction module 10 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 to form a humid circulating airflow.

[0037] The dehumidification module 20 includes a turntable and a drive assembly. The turntable is located within the air duct between the outlet of the circulating fan and the inlet of the receiving cavity to dehumidify the humid circulating airflow. The drive assembly may include a motor that drives the turntable to rotate. The turntable can 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.

[0038] The heating module 30 includes a regeneration air duct and a heating module 30 disposed on the regeneration air duct, and the heating module 30 is also located above at least another part of the turntable. The heating module 30 includes multiple heating tubes connected end to end, and the heating tubes are 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, which allows the heating tubes to be distributed with a longer length in the accommodating area of ​​the heating module 30, thereby increasing the contact area with the regeneration airflow in the regeneration air duct, and thus improving the efficiency of heat exchange with the regeneration airflow.

[0039] The heating module 30 heats the dried regeneration airflow in the regeneration duct. The heated regeneration airflow passes through a turntable to heat and dehydrate the portion of the turntable located below the heating module 30, thus bringing this portion of the turntable to a temperature close to that of the heating module 30. Then, as the drive assembly drives the turntable to rotate, this portion rotates onto the circulation channel. Here, this portion can absorb moisture from the humid circulating airflow in the receiving cavity, making the humid circulating airflow dry, and 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 heating module 30 to the humid circulating airflow, thus making the humid circulating airflow dry and at a certain temperature. It can also ensure a relatively stable change in the humidified circulating airflow after drying and heating, without a temperature surge. Consequently, the gas flowing out of the receiving cavity, i.e., the humid circulating airflow, will also change relatively stably without a temperature surge. Then, the circulating airflow flows into the receiving cavity through the air inlet of the receiving cavity, making full contact with the object to be dried in the receiving cavity to dry the object. As the turntable rotates, after drying and heating the wet circulating airflow, this part of the turntable rotates back to the bottom of the heating module 30, so that the dried regenerated airflow heated by the heating module 30 can reheat and dry this part, thus maintaining the reusability of the turntable.

[0040] It is understandable that the air duct between the air outlet of the receiving cavity and the air inlet of the circulation module, the air duct between the air outlet of the circulation module and the air inlet of the dehumidification module 20, and the air duct between the air outlet of the dehumidification module 20 and the air inlet of the receiving cavity together form a circulation air duct. This circulation air duct and the regeneration air duct are two independent air ducts to minimize the mutual flow between the humid circulation airflow and the regeneration airflow. Therefore, it is beneficial for the turntable to continuously adsorb moisture and dehydrate and dry during the rotation process, so that the turntable always has good water absorption capacity, thereby improving the efficiency and effect of moisture absorption.

[0041] The temperature and humidity detection component 40 detects the real-time humidity and temperature values ​​of the humidified circulating airflow. The real-time humidity and temperature values ​​of the humidified circulating airflow are similar to the real-time humidity and temperature values ​​inside the containment cavity, and can therefore be considered approximately equal.

[0042] In practical applications, the controller of the household appliance containing the drying module can control the suction module 10, the dehumidification module 20, and the heating module 30 based on the real-time humidity and temperature values ​​of the wet circulating airflow to dry the objects to be dried in the containment cavity. This greatly reduces the number of detection components, which not only facilitates installation but also reduces costs.

[0043] Specifically, the controller's workflow is as follows: Figure 4 As shown, it includes:

[0044] Step 401: Determine the preset temperature range to which the real-time temperature value belongs.

[0045] Step 402: Obtain the target average power value of the heating module 30 corresponding to the preset temperature range.

[0046] Each preset temperature range has a corresponding average power value for the heating module 30, which can be set by the staff.

[0047] For example, taking four preset temperature ranges as an example, the average power value of the heating module 30 corresponding to [0, 28℃] is the rated power, the average power value of the heating module 30 corresponding to [28℃, 40℃] is 82% of the rated power, the average power value of the heating module 30 corresponding to [40℃, target_T-3℃] is 72% of the rated power, and the average power value of the heating module 30 corresponding to [target_T-3℃, target_T+3℃] is less than or equal to 75% of the rated power. Among them, the value of target_T is in the range of 70℃-90℃. The specific value can be set by the operator according to the target temperature range to be maintained by the temperature of the humidified circulating airflow. This embodiment does not strictly limit it. For example, if the target temperature range of the humidified circulating airflow is 80℃-86℃, then target_T can be 83℃.

[0048] By finding the preset temperature range to which the real-time temperature value belongs, the average power value of the corresponding heating module 30 is determined, which is also the target average power value of the heating module 30. For example, if the real-time temperature value is 35°C, then the target average power value of the heating module 30 is 82% of the rated power.

[0049] Step 403: Control the heating module 30 to turn on periodically, and adjust the on-time of the heating module 30 in each cycle so that the average power of the heating module 30 reaches the target average power value, so that the temperature value of the humid circulating airflow is maintained within the target temperature range. Then, based on the weight of the object to be dried, determine the first drying threshold, and based on the real-time temperature value and the real-time humidity value, determine the real-time moisture content of the humid circulating airflow flowing out of the accommodating cavity.

[0050] The heating module 30 can be turned on periodically. In each cycle, the heating module 30 is turned on for a period of time and then turned off for a period of time. That is to say, the heating film group is turned on intermittently and is not always on. The duration of each cycle is the sum of the on and off times of the heating module 30 within that cycle.

[0051] The average power value of heating module 30 is the ratio of the duration of heating module 30 being turned on to the duration of the cycle, multiplied by the rated power of heating module 30. The specific formula is as follows:

[0052]

[0053] in, P represents the average power value of the heating module 30, t1 represents the duration of the heating module 30 being turned on within one cycle, and t represents the duration of one cycle. t This refers to the rated power of the heating module 30. For example, the rated power P of the heating module 30... t Given 2000W, t = 60s, and t1 = 30s, then...

[0054] Step 404: Determine whether the real-time moisture content is less than or equal to the first dryness threshold. If it is less than or equal to the first dryness threshold, proceed to step 405.

[0055] Step 405: Control the heating module 30 to stop working.

[0056] For example, assuming the first dryness threshold is 80g / kg, if the real-time moisture content is 60g / kg, then the heating module 30 is controlled to stop working.

[0057] In this embodiment, when the real-time moisture content of the humidified circulating airflow is low, that is, when the moisture content of the object to be dried is low, the heating module 30 stops heating, thereby avoiding damage to the clothes due to a sharp increase in temperature when the clothes are almost dry. It also allows for more precise control of the working time of the heating module 30, reducing power consumption and saving resources.

[0058] Step 406: Calculate the difference between the first humidity value when the heating module 30 stops and the second humidity value after the heating module 30 has stopped working for a preset time.

[0059] 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 when the heating module stops working for a preset period of time.

[0060] The difference between the first humidity value and the second humidity value is calculated. The difference = first humidity value - second humidity value. This difference can be positive or negative. That is, the second humidity value after the heating module 30 has stopped working for a preset time may be less than, equal to, or greater than the first humidity value at the time the heating module stopped working. Less than indicates that the humidity decreased after the preset time; equal to indicates that the humidity remained the same; and greater than indicates that the humidity increased. 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 two 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 two humidity values ​​is -20 g / kg. Further, it is determined whether the difference is greater than or equal to a second desiccation threshold.

[0061] The preset duration can be set by the staff according to the actual situation; this embodiment does not impose strict requirements. In some embodiments, the preset duration can be 5 minutes.

[0062] 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 humidity value and the second humidity value is 20 g / kg.

[0063] Step 407: Determine whether the difference is greater than or equal to the second interference threshold. If it is greater than or equal to the second interference threshold, proceed to step 408. If it is less than the second interference threshold, proceed to step 409.

[0064] The second threshold for interference is a positive number, and the second threshold can be set by the staff according to the actual situation. This embodiment does not impose strict requirements.

[0065] Step 408: Control the suction module 10 and the dehumidification module 20 to stop working.

[0066] Step 409: If the real-time humidity value is lower than the second humidity value, control the suction module 10 and the dehumidification module 20 to stop working.

[0067] The system determines whether the difference is greater than or equal to the second drying threshold. 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 30 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. The system then controls the suction module 10 and the dehumidification module 20 to stop working, thus completing the drying process.

[0068] If the difference is less than the second drying threshold and the difference is positive, it means that the humidity has decreased slightly since the heating module 30 stopped working after a preset time, and 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 10 and the dehumidification module 20 still need to continue working.

[0069] If the difference is less than the second drying threshold and the difference is negative, it means that the humidity has increased relative to when the heating module 30 stopped working after 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 humidity value and the second humidity value is -20g / kg. The difference is less than the second drying threshold and is negative, so the second drying condition is not met, indicating that the object to be dried has not been dried, and the suction module 10 and the dehumidification module 20 still need to continue working.

[0070] When the difference between the measured humidity and the measured humidity is less than the second drying threshold, the heating module 30 is further activated for drying. The real-time humidity value is compared with the first humidity value to determine whether the suction module 10 and the dehumidification module 20 should stop working. Specifically, the real-time humidity value is compared with the first humidity value. If the real-time humidity value is less than or equal to the first humidity value, the heating module 30, suction module 10, and dehumidification module 20 are stopped, ensuring the object is completely dried and allowing for more accurate control of the overall drying time. If the real-time humidity value is greater than the first humidity value, the heating module 30, suction module 10, and dehumidification module 20 continue to operate. For example, assuming the first humidity value is 40 g / kg, if the real-time humidity value is 35 g / kg, then the suction module 10 and dehumidification module 20 are stopped, meaning the drying process ends.

[0071] In this embodiment, the re-drying judgment can accurately control the working time of the suction module 10 and the dehumidification module 20, that is, it can accurately control the drying end time, thereby ensuring the drying effect and improving the accuracy of the overall drying time control, saving resources.

[0072] 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.

[0073] In one embodiment, the weight of the object to be dried can be obtained by having the receiving cavity rotate at a preset speed for a certain period of time driven by the motor of a household appliance. Specifically, during the rotation of the receiving cavity, the eccentricity of the receiving cavity is measured by vibration sensors, acceleration sensors, etc., and then the weight of the object to be dried is determined by the preset correspondence between the rotation speed, eccentricity, and weight of the object to be dried, thereby obtaining the weight of the dried object. The preset correspondence between the rotation speed, eccentricity, and 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 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.

[0074] 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 embodiment does not strictly limit the method of obtaining the object to be dried.

[0075] In one embodiment, 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. This correspondence can be a mathematical function expression, a correspondence table, a correspondence curve, etc. This embodiment does not impose specific limitations.

[0076] For example, the first drying threshold can be obtained by looking up a table. Specifically, 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.

[0077] Alternatively, the first drying threshold can be calculated using a mathematical function based on the weight of the object to be dried. For example, a mathematical function can be established beforehand based on the weight of different objects to be dried and their corresponding first drying thresholds. This mathematical function 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.

[0078] In one embodiment, there is a correspondence between real-time humidity content and real-time temperature and humidity values. The real-time humidity content can be determined based on this correspondence. This correspondence can be a mathematical function expression, a correspondence table, a correspondence curve, etc. This embodiment does not impose specific limitations.

[0079] For example, real-time humidity content can be obtained by looking up a table. Specifically, different tables corresponding to real-time temperature and humidity values ​​and real-time humidity content can be pre-set. Then, by looking up the table using the measured real-time temperature and humidity values, the corresponding real-time humidity content can be found, thereby reducing the computational requirements of the controller.

[0080] Alternatively, real-time humidity can be calculated using real-time temperature and humidity values ​​through a mathematical function. In practical applications, the real-time temperature is always greater than 0℃. For example, the saturated water vapor partial pressure can be calculated using the Goff-Gratch equation based on the real-time temperature value. Then, the real-time humidity can be calculated using the saturated water vapor partial pressure and the real-time humidity value. The calculation process is as follows:

[0081] 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);

[0082] Ps = 10^lgPs;

[0083] D = 622φPs / (P'-φPs);

[0084] 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 real-time humidity value, D is the real-time moisture content, and P' is the reference atmospheric pressure, taken as 102000 Pa.

[0085] In some embodiments, the temperature and humidity detection component 40 is located on the air duct between the air outlet of the receiving cavity and the air inlet of the suction module 10, thereby enabling the temperature and humidity detection component 40 to detect the humid circulating airflow that has just flowed out of the receiving cavity, so that the detected temperature and humidity results are closer to the real-time temperature and real-time humidity values ​​in the receiving cavity.

[0086] In other embodiments, such as Figure 1 As shown, the temperature and humidity detection component 40 is located on the air duct between the air outlet of the suction module 10 and the air inlet of the dehumidification module 20, so that it can obtain a more accurate temperature and humidity value in the containment cavity and facilitate the installation of the temperature and humidity detection component.

[0087] Staff can choose either of the above two methods to install the temperature and humidity detection component 40 according to the actual situation, thereby improving the flexibility of the installation of the temperature and humidity detection component 40.

[0088] Specifically, such as Figures 1 to 3 As shown, the temperature and humidity detection component 40 includes a first mounting part 401 and a detection chip 402 disposed on the first mounting part 401. A second mounting part 403 is provided on the air duct between the air outlet of the receiving cavity and the air inlet of the dehumidification module 20. The first mounting part 401 is connected to the second mounting part 403.

[0089] The detection chip 402 is an existing integrated circuit board that can detect humidity and temperature. The specific structure of the detection chip 402 will not be described in detail here.

[0090] In specific applications, the second mounting part 403 can be installed in the air duct between the air outlet of the receiving cavity and the air inlet of the suction module 10, or it can be installed in the air duct between the air outlet of the suction module 10 and the air inlet of the dehumidification module 20.

[0091] With the cooperation of the first mounting part 401 and the second mounting part 403, the temperature and humidity detection component 40 can be installed on the air duct between the air outlet of the receiving cavity and the air inlet of the dehumidification module 20, thereby facilitating the installation of the temperature and humidity detection component 40.

[0092] Furthermore, such as Figure 2 As shown, the first mounting part 401 includes a first connecting part 4011 and a support part 4012 connected to the first connecting part 4011. The support part 4012 is provided with a first cavity 4013, and the detection chip 402 is located in the first cavity 4013.

[0093] The first cavity 4013 provides a space for the detection chip 402 and can also accommodate a certain amount of humidified circulating airflow, thereby enabling the detection chip 402 to fully contact the humidified circulating airflow.

[0094] Furthermore, the first connecting part 4011 and the supporting part 4012 are integrally formed, thereby eliminating the assembly process and improving the stability of the connection between the two. In addition, the sealing performance of the first mounting part 401 is also improved.

[0095] Furthermore, such as Figures 1 to 3 As shown, the second mounting part 403 includes a second connecting part 4031 and a second cavity 4032. The second cavity 4032 is disposed on the air duct between the air outlet of the receiving cavity and the air inlet of the dehumidification module 20. The second cavity 4032 is at least partially connected to the air duct between the air outlet of the receiving cavity and the air inlet of the dehumidification module 20. The second connecting part 4031 is connected to the first connecting part 4011, and the first cavity 4013 is connected to the second cavity 4032.

[0096] By connecting the first connecting part 4011 and the second connecting part 4031, the first connecting part 4011 can be fixed on the outer wall of the air duct between the air outlet of the receiving cavity and the air inlet of the dehumidification module 20, that is, the detection chip 402 is encapsulated in the cavity formed by the first cavity 4013 and the second cavity 4032.

[0097] The second cavity 4032 is at least partially connected to the air duct between the air outlet of the receiving cavity and the air inlet of the dehumidification module 20. Specifically, the bottom wall of the second cavity 4032 is provided with an opening 4033. The second cavity 4032 is connected to the air duct between the air outlet of the receiving cavity and the air inlet of the dehumidification module 20 through the opening 4033, so that the humid circulating airflow in the air duct can flow into the second cavity 4032 and then flow into the first cavity 4013, so that the detection chip 402 can fully contact the humid circulating airflow to accurately measure the real-time temperature and real-time humidity values ​​of the humid circulating airflow.

[0098] Furthermore, such as Figure 2 and Figure 3 As shown, the first connecting part 4011 includes at least one connecting seat 40111 and a first fixing member.

[0100] The number of connecting seats 40111, the first fixing member, and the connecting post can be set by the staff according to actual needs. In some embodiments, there are two connecting seats 40111, the first fixing member, and the connecting post, that is, one connecting seat 40111 is provided on each side of the first cavity 4013, and one connecting post is provided on each side of the second cavity 4032, so that the first connecting part 4011 is more firmly fixed on the outer wall of the air duct between the air outlet of the receiving cavity and the air inlet of the dehumidification module 20.

[0101] In one embodiment, a through hole is provided in the air duct between the air outlet of the receiving cavity and the air inlet of the dehumidification module. The second connecting part 4031 includes a second fixing member, and the second connecting part 4031 can be installed on the air duct by utilizing the second fixing member and the through hole in the air duct. The second fixing member can be a bolt, rivet, etc., and this embodiment does not strictly limit the first fixing member.

[0102] In another embodiment, a through hole is provided on the air duct between the air outlet of the receiving cavity and the air inlet of the dehumidification module. The first fixing member, the connecting seat 40111 having a through hole 40112 and the air duct having a through hole on the air duct can be used to connect the first connecting part 4011, the second connecting part 4031 and the air duct.

[0103] Furthermore, a sealing element is provided between the outer periphery of the first cavity 4013 and the outer periphery of the second cavity 4032.

[0104] The sealing element adopts a sheet-like sealing ring, which can prevent moisture from the humid circulating airflow from leaking through the gap between the first cavity 4013 and the second cavity 4032, and can also reduce the heat exchange between the humid circulating airflow and the outside, thereby improving the accuracy of the test results.
