Description

Technical Field

[0001] This application relates to the field of clothing drying technology, and in particular to a clothing drying method and clothing drying equipment. Background Technology

[0002] Currently, most tumble dryers use the same motor to control both the drum and the fan. The drum and fan are connected to the motor's output shaft. When the motor drives the drum to rotate, the fan rotates accordingly, providing a stable airflow to ensure continuous and efficient drying. However, if the motor runs in only one direction, the drum will also rotate in one direction. Clothes constantly tumbling in one direction can easily become tangled and knotted, affecting drying efficiency and resulting in clothes that are not fully dried or dried unevenly.

[0003] To address the issue of poor clothes drying performance, a bidirectional motor configuration was proposed. However, when the motor rotates in the reverse direction, the fan's output airflow will decrease significantly. If the motor rotates in the reverse direction for a long time, it will affect heat exchange during the drying process, making it impossible to dry clothes evenly. If the motor rotates in the reverse direction for a short time, clothes will still easily become tangled, resulting in uneven drying. Summary of the Invention

[0004] To address the problem of uneven drying of clothes, this application provides a method and related apparatus for drying clothes.

[0005] According to one aspect of the embodiments of this application, a clothes drying method is disclosed, applied in a clothes drying device. The clothes drying device includes a drive motor, a drum, and a circulating fan. The output shaft of the drive motor is connected to the drum and the circulating fan, and is used to drive the drum and the circulating fan to rotate. The circulating fan is used to drive the airflow inside the drum. The method includes:

[0006] Obtain the clothes drying parameters and determine whether the clothes drying parameters meet the preset conditions;

[0007] If the clothes drying parameters meet the preset conditions, control the drive motor to operate in the first mode;

[0008] If the clothes drying parameters do not meet the preset conditions, control the drive motor to operate in the second mode;

[0009] Wherein, when the clothes drying parameters meet the preset conditions, the humidity of the clothes in the drum is greater than when the clothes drying parameters do not meet the preset conditions, and the ratio of the forward and reverse rotation time of the drive motor in the second mode is less than the ratio of the forward and reverse rotation time of the drive motor in the first mode.

[0010] In one exemplary embodiment, the reverse rotation speed of the drive motor is greater than the forward rotation speed in both the first mode and the second mode, and the reverse rotation speed of the drive motor in the second mode is less than the reverse rotation speed of the drive motor in the first mode.

[0011] In one exemplary embodiment, the step of acquiring clothing drying parameters and determining whether the clothing drying parameters meet preset conditions includes:

[0012] The system obtains at least one of the following: drying program running time, exhaust temperature, return air temperature, and clothing humidity value. The drying program running time, exhaust temperature, return air temperature, and clothing humidity value are each used as a judgment parameter. The return air temperature is the outlet air temperature of the drum. The exhaust temperature is the heat exchanger temperature at the outlet of the heat pump system. The heat pump system heats the outlet air of the drum and outputs it, which is then sent into the drum by the circulating fan. The clothing humidity value is the humidity of the clothing in the drum.

[0013] Determine whether the determination parameters meet the preset conditions;

[0014] If any judgment parameter meets the preset conditions, it is determined that the clothes drying parameters meet the preset conditions; if none of the judgment parameters meet the preset conditions, it is determined that the clothes drying parameters do not meet the preset conditions.

[0015] In one exemplary embodiment, when the clothes drying parameters include the drying program runtime, determining whether the determination parameters meet preset conditions includes:

[0016] The drying program's running time and the preset running time are compared;

[0017] If the drying program runs for less than the preset running time, it is determined that the drying program runs for more than the preset running time. If the drying program runs for more than the preset running time, it is determined that the drying program runs for less than the preset running time.

[0018] When the clothes drying parameters include exhaust temperature or return air temperature, determining whether the determination parameters meet preset conditions includes:

[0019] Compare the exhaust temperature or return air temperature with the preset temperature;

[0020] If the exhaust temperature or return air temperature is below the preset temperature, it is determined that the exhaust temperature or return air temperature meets the preset conditions; if the exhaust temperature or return air temperature reaches or exceeds the preset temperature, it is determined that the exhaust temperature or return air temperature does not meet the preset conditions.

[0021] When the clothes drying parameters include the clothes humidity value, determining whether the determination parameters meet preset conditions includes:

[0022] Compare the humidity value of the clothing with the preset humidity value;

[0023] If the humidity value of the clothing reaches or exceeds the preset humidity value, it is determined that the humidity value of the clothing meets the preset conditions; if the humidity value of the clothing is below the preset humidity value, it is determined that the humidity value of the clothing does not meet the preset conditions.

[0024] In one exemplary embodiment, before acquiring the clothes drying parameters and determining whether the clothes drying parameters meet preset conditions, the method further includes a rotation speed determination step, which includes:

[0025] Obtain the weight of the clothes in the drum;

[0026] Based on the weight of the clothing, the forward and reverse rotation speeds of the drive motor are determined in the first and second modes, wherein the forward and reverse rotation speeds are positively correlated with the weight of the clothing.

[0027] In one exemplary embodiment, the method further includes an interference determination step, which includes:

[0028] Obtain the humidity value of the clothes in the drum within a preset time period;

[0029] If the humidity value of the clothes is below the target humidity value at all times within the preset time period, the clothes are determined to be dry and the drying process ends.

[0030] If the humidity value of the clothes reaches or exceeds the target humidity value at any time within the preset time period, it is determined that the clothes are not dry and the drying program continues to run.

[0031] In one exemplary embodiment, the method further includes an interference determination step, which includes:

[0032] Obtain the humidity value of the clothes in the drum within a preset time period;

[0033] If the humidity value of the clothes is below the target humidity value at all times within the preset time period, the clothes are determined to be dry and the drying process ends.

[0034] If the humidity value of the clothing reaches or exceeds the target humidity value at any time within the preset time period, the return air temperature and the intake air temperature are obtained. The return air temperature is the outlet air temperature of the drum, and the intake air temperature is the heat exchanger temperature at the inlet of the heat pump system. The heat pump system heats the outlet air of the drum and outputs it, which is then sent into the drum by the circulating fan.

[0035] Calculate the return air temperature growth rate and the temperature difference between the return air temperature and the intake air temperature. If the return air temperature growth rate reaches or exceeds a preset growth rate and / or the temperature difference reaches or exceeds a preset difference, it is determined that the clothes are dried and the drying program ends; otherwise, it is determined that the clothes are not dried and the drying program continues to run.

[0036] According to one aspect of the embodiments of this application, a clothes drying control device is disclosed, which is disposed in a clothes drying equipment. The clothes drying equipment includes a drive motor, a drum, and a circulating fan. The output shaft of the drive motor is connected to the drum and the circulating fan, and is used to drive the drum and the circulating fan to rotate. The circulating fan is used to drive the air flow inside the drum. The clothes drying control device includes:

[0037] The processing module is used to acquire clothing drying parameters and determine whether the clothing drying parameters meet preset conditions.

[0038] The control module is configured to control the drive motor to operate in a first mode when the clothes drying parameters meet preset conditions, and to control the drive motor to operate in a second mode when the clothes drying parameters do not meet preset conditions; wherein, when the clothes drying parameters meet preset conditions, the humidity of the clothes in the drum is greater than when the clothes drying parameters do not meet preset conditions, and the ratio of forward and reverse rotation time of the drive motor in the second mode is less than the ratio of forward and reverse rotation time of the drive motor in the first mode.

[0039] According to one aspect of the embodiments of this application, a clothes drying device is disclosed, which includes a drum, a circulating fan, a drive motor, one or more processors, and a memory, wherein the circulating fan is used to drive the airflow inside the drum; the output shaft of the drive motor is connected to the drum and the circulating fan, and is used to drive the drum and the circulating fan to rotate; the memory is used to store one or more programs, which, when executed by the one or more processors, cause the clothes drying device to perform the aforementioned method.

[0040] According to one aspect of the embodiments of this application, a computer-readable storage medium is disclosed, the computer-readable storage medium storing computer-readable instructions, which, when executed by a computer's processor, cause the computer to perform the aforementioned method.

[0041] The technical solutions provided by the embodiments of this application have at least the following beneficial effects:

[0042] The technical solution provided in this application acquires clothing drying parameters and determines whether these parameters meet preset conditions. If the parameters meet these conditions, it indicates that the clothes in the drum are relatively wet, requiring more hot air to enter the drum to ensure heat exchange during the drying process. Therefore, the drive motor is controlled to operate in a first mode, meaning the reverse rotation time of the drive motor is short, thus ensuring heat exchange during the drying process. If the parameters do not meet the preset conditions, it indicates that the clothes in the drum are relatively dry, and the demand for hot air is reduced. Therefore, the drive motor is controlled to operate in a second mode, meaning the reverse rotation time of the drive motor is longer, thereby increasing the reverse rotation time of the drum and fully untangling the tangled clothes, improving the uniformity of clothing drying. By controlling the drive motor to operate in different modes in stages, this application can effectively balance the heat exchange effect during the drying process and prevent clothes from tangling, thus improving the uniformity of clothing drying.

[0057] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

[0058] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0059] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0060] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0061] When the drum and circulating fan are controlled by the same drive motor, to prevent clothes from tangling, the relevant technology configures the drive motor to rotate bidirectionally, with the forward and reverse rotation time ratio of the drive motor remaining constant throughout the drying process. The applicant found that if the reverse rotation time is too short (e.g., a forward-to-reverse ratio of 60:1), the short time is insufficient to untangle clumps of clothing, leading to tangling and uneven drying. If the reverse rotation time is too long (e.g., a forward-to-reverse ratio of 1:1), the output airflow of the circulating fan decreases significantly during reverse rotation, resulting in very little hot air entering the drum, poor airflow within the drum, and poor heat exchange, again leading to uneven drying. For clothes drying equipment equipped with a heat pump system to exchange heat with the drum's exhaust air, the small amount of hot air entering the drum is insufficient to evaporate moisture from the clothes. This moisture enters the compressor of the heat pump system, causing liquid slugging and compressor malfunction, thus affecting the reliability of the heat pump system and resulting in incomplete drying of the clothes.

[0062] See Figure 1 , Figure 1 A flowchart of a prior art clothes drying method is shown, such as... Figure 1 As shown, during the entire drying process, the forward and reverse rotation speed ratio of the drive motor is fixed at R1:R2, and the forward and reverse rotation time ratio is fixed at t1:t2. Regardless of whether the forward and reverse rotation time ratio t1:t2 is set large or small, uneven drying of clothes persists. During the drying process, the humidity of the clothes in the drum is detected. When the detected humidity value is less than the humidity value h1, the clothes are judged to be dry, and the drying process ends. This drying logic is prone to misjudgment, especially when clothes are tangled. The humidity sensor only detects the surface humidity of the clothes, not the interior, leading to a misjudgment that the clothes are dry when they are not, again causing uneven drying.

[0063] Therefore, this application provides a method and related apparatus for drying clothes to improve the uniformity of drying clothes.

[0064] The following detailed description of the clothing drying method and related apparatus provided in this application, with reference to specific embodiments, provides a detailed explanation.

[0065] Figure 2 A schematic diagram of the partial structural components of a clothes drying device according to an embodiment of this application is shown; Figure 3 A schematic diagram of the air circulation structure of a clothes drying device according to an embodiment of this application is shown.

[0066] like Figure 2 and Figure 3As shown, the clothes drying equipment includes a cabinet 101, a front panel 102, a door 103, a circulating air duct 104, a circulating fan 105, a drum 106, a drive motor 107, a heat pump system, and a controller (not shown in the figure).

[0067] The housing 101 contains a storage space that accommodates components such as the circulating air duct 104, the roller 106, the drive motor 107, the heat pump system, and the controller.

[0068] The front panel 102 is located on the front side of the cabinet 101, and the front panel 102 is provided with a clothes loading port (not shown in the figure), which is connected to the drum 106. When the clothes loading port is open, the user can put the clothes to be dried into the drum 106 through the clothes loading port, or take out the dried clothes from the drum 106.

[0069] The door 103 is located on one side of the clothing inlet and is hinged to the front panel 102. The clothing inlet can be opened or closed by rotating the door 103.

[0070] The roller 106 is rotatably disposed inside the housing 101. When clothes need to be dried, the roller 106 is driven to rotate, so that the clothes are fully in contact with the hot air entering the roller 106 under the action of the roller 106, thereby achieving rapid drying of the clothes.

[0071] The circulating air duct 104 has an air inlet and an air outlet. The air outlet of the circulating air duct 104 is connected to the air inlet of the drum 106 so that the hot air in the circulating air duct 104 can enter the drum 106. The air inlet of the circulating air duct 104 is connected to the air outlet of the heat pump system.

[0072] A circulating fan 105 is installed in a circulating air duct 104. The circulating fan 105 can drive the dry hot air in the circulating air duct 104 to enter the drum 106 through the air outlet of the circulating air duct 104. At the same time, it drives the air flow in the drum 106, so that the air that has absorbed the moisture of the clothes is discharged from the drum 106. The air discharged from the drum 106 enters the heat pump system through the air inlet of the heat pump system for heat exchange, forming hot air, which then returns to the air inlet of the circulating air duct 104 through the air outlet of the heat pump system, and thus returns to the circulating air duct 104.

[0073] The output shaft of the drive motor 107 is connected to the drum 106 and the circulating fan 105. The drive motor 107 is used to drive the drum 106 and the circulating fan 105 to rotate. The rotation direction and speed of the drive motor 107 are adjustable, thereby adjusting the rotation direction and speed of the drum 106 and the circulating fan 105. When the drive motor 107 rotates in the forward direction (e.g., clockwise), both the drum 106 and the circulating fan 105 rotate in the forward direction. When the drive motor 107 rotates in the reverse direction (e.g., counterclockwise), both the drum 106 and the circulating fan 105 rotate in the reverse direction.

[0074] The heat pump system includes an evaporator 108, a condenser 109, a compressor 110, and a throttling device 111. The evaporator 108, compressor 110, condenser 109, and throttling device 111 are connected by pipes, which provide a pathway for the flow of heat exchanger (refrigerant) in the heat pump system. When the compressor 110 is running, the heat exchanger is supplied to the condenser 109 for heat release and condensation. Then, the heat exchanger passes through the throttling device 111 into the evaporator 108 for heat absorption and evaporation, and then returns to the compressor 110. The gas discharged from the drum 106 first passes through the evaporator 108 to cool down before flowing to the condenser 109. The heat released by the condenser 109 can heat the flowing gas, thereby forming hot air, which enters the circulation duct 104.

[0075] The controller is used to control the operation of various components of the clothes drying equipment, such as the drive motor 107, the circulating fan 105, and the heat pump system.

[0076] It should be noted that in some embodiments, other devices capable of heating air can be used to replace the heat pump system to generate hot air, such as electric heating devices.

[0077] Figure 4 A flowchart illustrating a clothing drying method according to an embodiment of this application is shown. This clothing drying method can be executed by a clothing drying device, specifically by the controller of the clothing drying device. (See also...) Figure 4 As shown, the clothes drying method includes at least steps S410 to S430, which are described in detail below:

[0078] In step S410, the clothes drying parameters are obtained, and it is determined whether the clothes drying parameters meet the preset conditions. If the clothes drying parameters meet the preset conditions, proceed to step S420a; if the clothes drying parameters do not meet the preset conditions, proceed to step S420b.

[0079] Specifically, when the clothes drying parameters meet the preset conditions, the humidity of the clothes in the drum is greater than when the clothes drying parameters do not meet the preset conditions. In other words, when the clothes drying parameters meet the preset conditions, it means that the clothes in the drum are relatively wet, and when the clothes drying parameters do not meet the preset conditions, it means that the clothes in the drum are relatively dry.

[0080] Among them, the clothes drying parameters can be at least one of the following: drying program running time, exhaust temperature, return air temperature, and clothes humidity value. Specifically, it can be any one of the following, or any two, or any three, or all of them.

[0081] The longer the drying program runs, the longer the clothes in the drum are dried, and the more moisture is removed from the clothes, resulting in lower humidity. Therefore, the drying program running time can be used as a parameter to determine the humidity of the clothes.

[0082] The return air temperature is the outlet air temperature of the drum. When the humidity of the clothes in the drum is high, the return air temperature is low because more water vapor mixes with the hot air. When the humidity of the clothes in the drum is low, the return air temperature is high because less water vapor mixes with the hot air. Therefore, the return air temperature can be used as a parameter to determine the humidity of the clothes.

[0083] The exhaust temperature is the temperature of the heat exchanger at the outlet of the heat pump system, which is also the temperature of the heat exchanger at the compressor outlet. When the clothes in the drum are highly humid, the large amount of water vapor mixed with the hot air results in a lower return air temperature. This causes the return air to carry away more heat during heat exchange with the heat pump system, leading to a decrease in the heat exchanger temperature. Conversely, when the clothes in the drum are less humid, the less water vapor mixed with the hot air results in a higher return air temperature. This causes the return air to carry away less heat during heat exchange with the heat pump system, leading to an increase in the heat exchanger temperature. Therefore, the exhaust temperature can be used as a parameter to determine the humidity of the clothes.

[0084] It should be noted that in some embodiments, the temperature of the hot air entering the circulating air duct can also be directly measured as the exhaust temperature.

[0085] In one embodiment of this application, in step S410, determining whether the clothes drying parameters meet the preset conditions includes: judging whether the judgment parameters meet the preset conditions; if any judgment parameter meets the preset conditions, determining that the clothes drying parameters meet the preset conditions; if all judgment parameters do not meet the preset conditions, determining that the clothes drying parameters do not meet the preset conditions.

[0086] When any parameter meets the preset conditions, it is determined that the clothes drying parameters meet the preset conditions. This can prevent the clothes from being mistakenly judged as not being dry when they are already relatively dry. It ensures that the drive motor operates in the appropriate mode, thereby preventing uneven drying of clothes or water vapor from entering the compressor and causing liquid slugging.

[0087] In detail, when the clothes drying parameters include the drying program running time, it is determined whether the parameters meet the preset conditions, including: comparing the drying program running time with the preset running time; if the drying program running time is less than the preset running time, it is determined that the drying program running time meets the preset conditions; if the drying program running time is greater than or equal to the preset running time, it is determined that the drying program running time does not meet the preset conditions.

[0088] The preset running time can be flexibly configured according to the actual operation of the clothes drying equipment. For example, the total duration of the entire drying program is 90 minutes, and the preset running time is 70 minutes. Before the drying program runs for 70 minutes, it is determined that the drying program runs for 70 minutes and meets the preset conditions. After the drying program runs for 70 minutes, it is determined that the drying program runs for 70 minutes and does not meet the preset conditions.

[0089] When the clothes drying parameters include exhaust temperature, it is determined whether the parameters meet the preset conditions, including: comparing the exhaust temperature with the preset temperature; if the exhaust temperature is below the preset temperature, it is determined that the exhaust temperature meets the preset conditions; if the exhaust temperature reaches or exceeds the preset temperature, it is determined that the exhaust temperature does not meet the preset conditions.

[0090] The preset temperature can be flexibly configured according to the actual operating conditions of the clothes drying equipment. For example, the preset temperature is 55℃.

[0091] When the clothes drying parameters include return air temperature, it is determined whether the parameters meet the preset conditions, including: comparing the return air temperature with the preset temperature; if the return air temperature is below the preset temperature, it is determined that the return air temperature meets the preset conditions; if the return air temperature reaches or exceeds the preset temperature, it is determined that the return air temperature does not meet the preset conditions.

[0092] The preset temperature can be flexibly configured according to the actual operating conditions of the clothes drying equipment. For example, the preset temperature is 50℃.

[0093] When the clothes drying parameters include the clothes humidity value, it is determined whether the parameters meet the preset conditions, including: comparing the clothes humidity value with the preset humidity value; if the clothes humidity value reaches or exceeds the preset humidity value, it is determined that the clothes humidity value meets the preset conditions; if the clothes humidity value is below the preset humidity value, it is determined that the clothes humidity value does not meet the preset conditions.

[0094] The preset humidity value can be flexibly configured according to the actual operating conditions of the clothes drying equipment. For example, the preset humidity value corresponds to a moisture content of 15% for the clothes.

[0095] like Figure 5 As shown, in one embodiment of this application, step S410 includes steps S510 to S530, which are described in detail below:

[0096] In step S510, four judgment parameters are obtained: drying program running time t, exhaust temperature T1, return air temperature T2, and clothing humidity value h.

[0097] In step S520, determine whether the following conditions are met: drying program running time t ≤ preset running time t0, exhaust temperature T1 ≤ preset temperature T10, return air temperature T2 ≤ preset temperature T20, or clothing humidity value h ≥ preset humidity value h0. If so (i.e., one or more judgment parameters are met), proceed to step S530a; otherwise (i.e., no judgment parameter is met), proceed to step S530b.

[0098] In step S530a, it is determined that the clothes drying parameters meet the preset conditions.

[0099] In step S530b, it is determined that the clothes drying parameters do not meet the preset conditions.

[0100] certainly, Figure 5 The flowchart shown is only one embodiment of step S410 in this application. In other embodiments, step S410 is not limited to the following. Figure 5 The steps are shown.

[0101] In step S420a, the drive motor is controlled to operate in the first mode.

[0102] In step S420b, the drive motor is controlled to operate in the second mode. Then, proceed to step S430.

[0103] In the second mode, the ratio of forward to reverse rotation time of the drive motor is smaller than that in the first mode. That is, in the second mode, the reverse rotation time of the drive motor is longer, while in the first mode, the reverse rotation time of the drive motor is shorter.

[0104] If the drying parameters meet the preset conditions, it means the clothes in the drum are relatively wet, requiring more hot air to ensure heat exchange during the drying process. Therefore, the drive motor is controlled to operate in the first mode, meaning the motor's reverse rotation time is short, thus ensuring heat exchange during drying. If the drying parameters do not meet the preset conditions, it means the clothes in the drum are relatively dry, and the demand for hot air is reduced. Therefore, the drive motor is controlled to operate in the second mode, meaning the motor's reverse rotation time is longer, increasing the drum's reverse rotation time to fully untangle tangled clothes and improve the evenness of drying. In other words, by controlling the drive motor to operate in different modes in stages, it is possible to effectively balance heat exchange during the drying process and prevent clothes from tangling, thereby improving the evenness of drying.

[0105] For example, in the first mode, the ratio of forward to reverse rotation time of the drive motor is 5 minutes of forward rotation to 30 seconds of reverse rotation; in the second mode, the ratio of forward to reverse rotation time of the drive motor is 4 minutes of forward rotation to 1 minute of reverse rotation.

[0106] In one embodiment of this application, in both the first and second modes, the reverse rotation speed of the drive motor is greater than the forward rotation speed. When the drive motor rotates in the reverse direction, the output air volume of the drive fan will decrease significantly. Therefore, increasing the reverse rotation speed of the drive motor increases the output air volume when the drive motor rotates in the reverse direction, allowing more hot air in the circulating air duct to enter the drum to participate in heat exchange, thereby removing moisture from the clothes, which is beneficial for even drying of the clothes, and the operation of the heat pump system is also more reliable.

[0107] In one embodiment of this application, the reverse rotation speed of the drive motor in the second mode is less than that in the first mode. When the clothes in the drum are wet, the reverse rotation speed of the drive motor is set to be larger to increase the output air volume when the drive motor reverses. When the clothes in the drum are dry, the reverse rotation speed of the drive motor is appropriately reduced to save energy consumption of the drive motor and reduce the vibration problem of the housing caused by the high speed of the drive motor.

[0108] For example, in the first mode, the forward speed of the drive motor is 2500 rpm and the reverse speed is 2800 rpm; in the second mode, the forward speed of the drive motor is 2500 rpm and the reverse speed is 2700 rpm.

[0109] For example, in the first mode, the forward and reverse rotation time ratio of the drive motor is 5 minutes of forward rotation / 30 seconds of reverse rotation, the forward rotation speed of the drive motor is 2500 rpm, and the reverse rotation speed is 2800 rpm; in the second mode, the forward and reverse rotation time ratio of the drive motor is 4 minutes of forward rotation / 1 minute of reverse rotation, the forward rotation speed of the drive motor is 2500 rpm, and the reverse rotation speed is 2700 rpm.

[0110] In one embodiment of this application, the forward and reverse rotation speeds of the drive motor in the first and second modes are determined based on the weight of the clothes in the drum. Specifically, before executing step S410, the following steps are performed: obtaining the weight of the clothes in the drum; and determining the forward and reverse rotation speeds of the drive motor in the first and second modes based on the weight of the clothes. Since the greater the weight of the clothes in the drum, the greater the wind resistance, and the smaller the weight of the clothes in the drum, the smaller the wind resistance, in this embodiment, the forward and reverse rotation speeds are configured to be positively correlated with the weight of the clothes, so that the rotation speed of the drive motor is adapted to the actual needs.

[0111] In step S430, it is determined whether the clothes are dry. If the clothes are determined to be dry, the drying process ends; if the clothes are determined not to be dry, the drying process continues.

[0112] like Figure 6 As shown, in one embodiment of this application, step S430 includes steps S610 to S630, which are described in detail below:

[0113] In step S610, the humidity value h of the clothes in the drum within a preset time period tn is obtained.

[0114] Specifically, a humidity sensor can be installed on the side wall of the drum or at the air outlet of the drum. The humidity sensor detects the humidity value of the clothes, thereby obtaining the humidity value h of the clothes in the drum within a preset time period tn.

[0115] In step S620, it is determined whether the humidity value h of the clothes at all times within the preset time period tn is less than or equal to the target humidity value h1. If so, proceed to step S630; otherwise (that is, at least at one time the humidity value h of the clothes is greater than the target humidity value h1), it is determined that the clothes are not dried and the drying program continues to run.

[0116] In step S630, it is determined that the clothes are dry and the drying process ends.

[0117] The preset time period tn is flexibly configured according to the actual operating conditions of the clothes drying equipment. For example, the preset time period tn is 3 minutes. The target humidity value h1 is also flexibly configured according to the actual operating conditions of the clothes drying equipment. For example, the target humidity value h1 is a moisture content of clothes between 0% and 1%.

[0118] exist Figure 6 In the embodiment shown, by increasing the number of humidity detections over a given time period, the clothes are determined to be dry only when the humidity value of the clothes at all times within the given time period is less than or equal to the target humidity value. If the humidity value of the clothes is greater than the target humidity value at any time, the clothes are determined to be not dry. This can prevent the clothes from being mistakenly judged as dry when they are not dry, and prevent uneven drying of clothes due to detection errors of the humidity sensor or local clumping of the clothes.

[0119] like Figure 7 As shown, in one embodiment of this application, step S430 includes steps S710 to S750, which are described in detail below:

[0120] In step S710, the humidity value h of the clothes in the drum within a preset time period tn is obtained.

[0121] In step S720, it is determined whether the humidity value h of the clothing at all times within the preset time period tn is less than or equal to the target humidity value h1. If so, proceed to step S730a; otherwise (i.e., at least at one time the humidity value h of the clothing is greater than the target humidity value h1), proceed to step S730b.

[0122] In step S730a, it is determined that the clothes are dry and the drying process ends.

[0123] In step S730b, the return air temperature and intake air temperature are obtained, and then the process proceeds to step S740.

[0124] In step S740, the return air temperature growth rate L and the temperature difference ΔT between the return air temperature and the intake air temperature are calculated.

[0125] The return air temperature is the outlet air temperature of the drum. When the humidity of the clothes in the drum is high, the return air temperature is low; when the humidity of the clothes in the drum is low, the return air temperature increases, and the rate of increase in return air temperature becomes faster and faster. Therefore, the return air temperature growth rate L gradually increases. Thus, the return air temperature growth rate L can be used as a criterion for determining the dryness of the clothes.

[0126] The suction temperature is the temperature of the heat exchanger at the inlet of the heat pump system, which is also the temperature of the heat exchanger at the compressor inlet. When the clothes in the drum are highly humid, the suction temperature and the return air temperature are approximately equal, meaning the temperature difference ΔT between the return air temperature and the suction temperature is small. The suction temperature is configured to gradually decrease as the clothes dry, while the return air temperature gradually increases, and the temperature difference ΔT becomes increasingly larger, eventually reaching its maximum value. Therefore, the temperature difference ΔT between the return air temperature and the suction temperature can be used as a criterion for determining whether the clothes are dry.

[0127] In step S750, it is determined whether the return air temperature growth rate L ≥ preset growth rate L0 or the temperature difference ΔT between the return air temperature and the intake air temperature ≥ preset difference T3. If so (i.e., one or both are satisfied), proceed to step S730a; otherwise (i.e., none of them are satisfied), it is determined that the clothes are not dried and the drying program continues to run.

[0128] The preset growth rate L0 is flexibly configured based on the actual operating conditions of the clothes drying equipment. For example, the preset growth rate L0 is a temperature increase of 5°C within 3 minutes. The preset difference T3 is also flexibly configured based on the actual operating conditions of the clothes drying equipment. For example, the preset difference T3 is 20°C.

[0129] exist Figure 7 In the illustrated embodiment, with Figure 6 The difference in the embodiment shown is that, if the humidity value h of the clothes is not less than the target humidity value h1 at all times within the preset time period tn, a temperature detection and stop logic is further performed. This can prevent the humidity sensor from being affected by power grid fluctuations and humidity voltage, which could lead to inaccurate humidity detection of the clothes and cause the clothes to be mistakenly judged as not dry when they are already dry, thus preventing the clothes from being over-dried.

[0130] Figure 8 A flowchart of a clothes drying method according to an embodiment of this application is shown. (See attached document.) Figure 8 As shown, the clothes drying method includes at least steps S810 to S840, which are described in detail below:

[0131] In step S810, four judgment parameters are obtained: drying program running time t, exhaust temperature T1, return air temperature T2, and clothing humidity value h. It is then determined whether the following conditions are met: drying program running time t ≤ preset running time t0, exhaust temperature T1 ≤ preset temperature T10, return air temperature T2 ≤ preset temperature T20, or clothing humidity value h ≥ preset humidity value h0. If so (i.e., one or more judgment parameters are met), proceed to step S820a; otherwise (i.e., no judgment parameter is met), proceed to step S820b.

[0132] In step S820a, the drive motor is controlled to operate in the first mode.

[0133] In step S820b, the drive motor is controlled to operate in the second mode.

[0134] In step S830, the humidity value h of the clothes in the drum within a preset time period tn is obtained, and it is determined whether the humidity value h of the clothes at all times within the preset time period tn is less than or equal to the target humidity value h1. If yes, proceed to step S840a; otherwise (that is, at least at one time the humidity value h of the clothes is greater than the target humidity value h1), proceed to step S840b.

[0135] In step S840a, it is determined that the clothes are dry and the drying process ends.

[0136] In step S840b, the return air temperature and the intake air temperature are obtained, and the return air temperature growth rate L and the temperature difference ΔT between the return air temperature and the intake air temperature are calculated. Then, it is determined whether the return air temperature growth rate L ≥ preset growth rate L0 or the temperature difference ΔT between the return air temperature and the intake air temperature ≥ preset difference T3 is satisfied. If so (i.e., one or both are satisfied), proceed to step S840a; otherwise (i.e., none of them are satisfied), it is determined that the clothes are not dried, return to step S830, and continue running the drying program.

[0137] Corresponding to the aforementioned embodiments of the clothing drying method, this application also provides a clothing drying control device.

[0138] See Figure 9 , Figure 9 This diagram illustrates a block diagram of a clothes drying control device according to an embodiment of this application. This device can be applied to the controller of a clothes drying equipment to perform... Figures 4 to 8 All or part of the steps of any of the illustrated clothes drying methods. For example... Figure 9 As shown, the device 900 includes, but is not limited to, a processing module 901 and a control module 902.

[0139] The processing module 901 is used to acquire clothes drying parameters and determine whether the clothes drying parameters meet preset conditions.

[0140] The control module 902 is used to control the drive motor to operate in a first mode when the clothes drying parameters meet the preset conditions, and to control the drive motor to operate in a second mode when the clothes drying parameters do not meet the preset conditions.

[0141] Specifically, when the clothes drying parameters meet the preset conditions, the humidity of the clothes in the drum is greater than when the clothes drying parameters do not meet the preset conditions. In other words, when the clothes drying parameters meet the preset conditions, it means that the clothes in the drum are relatively wet, and when the clothes drying parameters do not meet the preset conditions, it means that the clothes in the drum are relatively dry.

[0142] In the second mode, the ratio of the forward and reverse rotation time of the drive motor is smaller than that in the first mode. In other words, in the second mode, the reverse rotation time of the drive motor is longer, while in the first mode, the reverse rotation time of the drive motor is shorter.

[0143] In some embodiments of this application, based on the aforementioned scheme, the reverse rotation speed of the drive motor is greater than the forward rotation speed in both the first mode and the second mode, and the reverse rotation speed of the drive motor is less than the reverse rotation speed of the drive motor in the first mode in the second mode.

[0145] In some embodiments of this application, based on the foregoing scheme, the processing module 901 is configured to: when the clothes drying parameters include the drying program running time, compare the drying program running time with a preset running time; if the drying program running time is below the preset running time, determine that the drying program running time meets the preset conditions; if the drying program running time reaches or exceeds the preset running time, determine that the drying program running time does not meet the preset conditions; when the clothes drying parameters include the exhaust temperature or return air temperature, compare the exhaust temperature or return air temperature with a preset temperature; if the exhaust temperature or return air temperature is below the preset temperature, determine that the exhaust temperature or return air temperature meets the preset conditions; if the exhaust temperature or return air temperature reaches or exceeds the preset temperature, determine that the exhaust temperature or return air temperature does not meet the preset conditions; when the clothes drying parameters include the clothes humidity value, compare the clothes humidity value with a preset humidity value; if the clothes humidity value reaches or exceeds the preset humidity value, determine that the clothes humidity value meets the preset conditions; if the clothes humidity value is below the preset humidity value, determine that the clothes humidity value does not meet the preset conditions.

[0146] In some embodiments of this application, based on the foregoing scheme, the device 900 further includes a rotation speed determination module 903, which is used to obtain the weight of the clothes in the drum; and determine the forward and reverse rotation speeds of the drive motor in the first mode and the second mode according to the weight of the clothes. The forward and reverse rotation speeds are positively correlated with the weight of the clothes.

[0147] In some embodiments of this application, based on the aforementioned scheme, the device 900 further includes a drying determination module 904, which is used to obtain the humidity value of the clothes in the drum within a preset time period; if the humidity value of the clothes at all times within the preset time period is below the target humidity value, it is determined that the clothes have been dried, and the drying process ends; if the humidity value of the clothes at any time within the preset time period reaches or exceeds the target humidity value, it is determined that the clothes have not been dried, and the drying process continues to run.

[0148] In some embodiments of this application, based on the aforementioned scheme, the device 900 further includes a drying determination module 904, which is used to obtain the humidity value of the clothes in the drum within a preset time period; if the humidity value of the clothes at all times within the preset time period is below the target humidity value, it is determined that the clothes are dried and the drying process ends; if the humidity value of the clothes at any time within the preset time period reaches or exceeds the target humidity value, the return air temperature and the intake air temperature are obtained, and the return air temperature growth rate and the temperature difference between the return air temperature and the intake air temperature are calculated; if the return air temperature growth rate reaches or exceeds the preset growth rate and / or the temperature difference reaches or exceeds the preset difference, it is determined that the clothes are dried and the drying process ends; otherwise, it is determined that the clothes are not dried and the drying process continues to run.
