[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] With the increasing popularity of heat pump dryers, their application areas are quite wide, and the operating environments vary considerably. During the drying process, heat pump dryers generate condensation due to heat exchange between the machine's internal and external components. Especially in environments with low temperature and high humidity or high temperature and high humidity, this condensation can accumulate inside the machine, such as in the casing and control board, potentially leading to electrical component failure and reducing the user experience.

[0025] Based on this, this application provides a control method for a clothes dryer. The clothes dryer includes an inner drum, a compressor, an air duct, and a cooling fan. The compressor exchanges heat with the inner drum through the air duct, and the cooling fan blows the hot air generated by the compressor to the outside of the dryer to cool the compressor. The control method includes: acquiring the initial temperature inside the air duct when the compressor is not started; determining a target drying mode from multiple drying modes based on the temperature range falling within the initial temperature, with each temperature range corresponding to a drying mode; starting the compressor and acquiring the working temperature inside the air duct; and controlling the operation of the cooling fan based on the target drying mode, the working temperature, and the initial temperature. The initial temperature inside the air duct is used as the ambient temperature and compared with the working temperature as the criterion for starting the cooling fan. The operation of the cooling fan is integrated into the drying process. By utilizing the existing components of the clothes dryer, condensation caused by the large temperature difference between the inside of the dryer and the ambient temperature can be reduced, thus reducing problems such as electrical component failure due to condensation accumulation and improving the user experience.

[0026] To reduce the impact of condensate on the internal electrical components of the dryer, embodiments of this application provide a dryer and its control method, control device, and storage medium, which will be described below in conjunction with the accompanying drawings.

[0027] Please see Figure 1 As shown, Figure 1 This is a first flowchart illustrating the control method for a clothes dryer provided in an embodiment of this application. The embodiment of this application provides a control method for a clothes dryer, wherein the dryer includes an inner drum, a compressor, an air duct, and a cooling fan. The inner drum is used to hold clothes and can be in the form of a roller drum, thus the clothes dryer can be a roller drum type dryer. The compressor is one of the main components in the dryer that performs the drying function. The compressor can be part of a heat pump system, and it is used to exchange heat with the inner drum through the air duct, thereby continuously expelling moisture from the clothes to dry them. The cooling fan is used to cool the heat pump system to prevent overheating, or in other words, the cooling fan is used to blow the heat generated by the compressor during operation to the outside of the dryer to cool the compressor. The control method for the clothes dryer includes: Step S110: Obtain the initial temperature inside the air duct when the compressor is not started.

[0028] The main reason why condensation easily forms inside a clothes dryer is the large temperature difference between the inside of the dryer and the ambient temperature, which is exacerbated by humidity. Therefore, it is necessary to obtain the temperature of the environment in which the dryer is located.

[0029] For example, the initial temperature inside the air duct can be used as the ambient temperature. When the compressor is not running, the temperature inside the air duct is similar to the ambient temperature outside the dryer. Therefore, the temperature inside the air duct can be used as the ambient temperature. Furthermore, the temperature can be collected using the temperature sensor already present in the air duct, thus eliminating the need for additional temperature sensors and improving the utilization efficiency of the device.

[0030] The initial temperature can be the average temperature over a period of time. For example, a temperature sensor inside the duct can continuously detect the temperature. If the compressor does not start within a preset time, the computer board can process the temperature data detected by the temperature sensor within the preset time and take the average value to obtain the initial temperature.

[0031] Step S120: Based on the temperature range in which the initial temperature falls, determine the target drying mode from multiple drying modes, with each temperature range corresponding to a drying mode.

[0032] The initial temperature inside the air duct can represent the ambient temperature. Based on the preset temperature range within which the initial temperature falls, the target drying mode is determined from multiple drying modes. The temperature range and drying mode correspond one-to-one, which can be achieved through a preset mapping table. The target drying mode can be determined based on the initial temperature range and the mapping table. Furthermore, the operating speed and start-up timing of the cooling fan differ across drying modes, thus adapting to the ambient temperature and mitigating condensation issues.

[0033] Step S130: Start the compressor and obtain the working temperature inside the air duct.

[0034] After obtaining the initial temperature, the drying program can be started. During the drying program, the compressor needs to be started and the temperature sensor in the air duct needs to continuously monitor the temperature change inside the air duct. The temperature inside the air duct during the compressor operation is taken as the working temperature, which is also the temperature inside the dryer. The greater the difference between the working temperature and the initial temperature, the easier it is for condensation to form inside the dryer.

[0035] Step S140: Control the operation of the cooling fan according to the target drying mode, working temperature and initial temperature.

[0036] The target drying mode, operating temperature, and initial temperature determine when the cooling fan should start and its operating speed. If the difference between the operating temperature and the initial temperature is too large, it indicates that the internal system temperature of the dryer is too high. In this case, the cooling fan speed can be increased to cool the inside of the dryer. Conversely, in target drying mode, the cooling fan's operating speed is dynamically adjusted based on the operating temperature and the initial temperature, thereby reducing the difference between the two temperatures and thus minimizing condensation.

[0037] In the control method for the dryer provided in this application embodiment, the initial temperature inside the air duct is used as the ambient temperature and compared with the working temperature as the judgment criterion for starting the cooling fan. The operation of the cooling fan is integrated into the drying program. By utilizing the original components of the dryer, the condensation caused by the large temperature difference between the inside of the dryer and the ambient temperature can be reduced. This can reduce problems such as electrical component failure caused by condensation accumulation, thereby improving the user experience.

[0038] The drying modes may include a first drying mode, a second drying mode, and a third drying mode, with different start-up times and operating speeds for the cooling fans in each mode. The temperature range corresponds one-to-one with the drying mode; please refer to one implementation example. Figure 2 As shown, Figure 2 This is a second flowchart illustrating the control method for a clothes dryer provided in an embodiment of this application. Step S120: Based on the temperature range within which the initial temperature falls, determine the target drying mode from multiple drying modes, where each temperature range corresponds one-to-one with a drying mode, including: Step S121: If the initial temperature is less than the first threshold, then select the first drying mode as the target drying mode.

[0039] Step S122: If the initial temperature is between the first threshold and the second threshold, then select the second drying mode as the target drying mode, where the second threshold is greater than the first threshold.

[0040] Step S123: If the initial temperature is greater than the second threshold, then select the third drying mode as the target drying mode.

[0041] Regarding steps S121 to S123: The initial temperature range is divided into three intervals using a first threshold and a second threshold. For example, the first threshold can be 20℃ and the second threshold can be 25℃. That is to say, when the initial temperature is less than 20℃, the first drying mode is selected as the target drying mode; when the initial temperature is between 20℃ and 25℃, the second drying mode is selected as the target drying mode; and when the initial temperature is greater than 25℃, the third drying mode is selected as the target drying mode.

[0042] Depending on the initial temperature range, the cooling fan operates differently in each drying mode. Please refer to [link / reference]. Figure 3 As shown, Figure 3 This is a third flowchart illustrating the control method for a clothes dryer provided in an embodiment of this application. In one implementation, step S140, controlling the operation of the cooling fan according to the target drying mode, operating temperature, and initial temperature, includes: Step S141: When the target drying mode is the first drying mode, the cooling fan is started and stopped at a timed interval after the compressor starts for the first time period and runs at the first speed.

[0043] Step S142: During the drying process, if the working temperature is greater than or equal to the first set temperature within the first time period, and the difference between the working temperature and the initial temperature is greater than or equal to the temperature threshold difference, then the cooling fan is controlled to speed up to the second speed, which is greater than the first speed.

[0044] Regarding steps S141 and S142: After determining the drying mode based on the initial temperature, such as when the target drying mode is determined to be the first drying mode based on the initial temperature, the cooling fan is started and runs at the first speed after the compressor starts for the first period. Alternatively, after the compressor starts, the cooling fan does not start during the first period, and then the cooling fan is periodically started and stopped. For example, the cooling fan's on duration can be set to 60 seconds, and its off duration to 40 seconds, and this frequency is repeated until the program ends, with the cooling fan operating at the first speed. This is because, since the initial temperature is below a first threshold, such as 20°C, while the temperature during drying usually exceeds 40°C, condensation is likely to accumulate in the first drying mode. To reduce condensation, after the compressor starts operating for the first period—which is also the system's heating phase—the cooling fan is used for heat dissipation as soon as the heating phase ends. This reduces the impact on the system's temperature rise and also reduces the temperature difference between the inside and outside of the system, thus reducing the risk of condensation.

[0045] Since the operating temperature in the air duct changes in real time, the cooling fan can also be dynamically adjusted. For example, during the drying process, if the temperature sensor detects that the operating temperature in the air duct is greater than or equal to a first set temperature for a first duration, and the difference between the operating temperature and the initial temperature is greater than or equal to a temperature threshold difference, then the cooling fan is controlled to increase its speed to a second speed, which is greater than the first speed.

[0046] For example, the first set temperature can be 60℃, and the temperature difference threshold can be 37℃. If the working temperature is continuously greater than 60℃ within the first time period, and the difference between the working temperature and the initial temperature is greater than or equal to the temperature difference threshold, it indicates that the system temperature is too high at this time. The cooling fan cannot be cooled down quickly by operating at the first speed. Therefore, the speed of the cooling fan is increased to the second speed.

[0047] In some embodiments, in order to improve the heat dissipation speed of the cooling fan, the start-stop ratio of the cooling fan at the second speed can be increased, such as the cooling fan being turned on for 60 seconds and the cooling fan being turned off for 30 seconds or 20 seconds.

[0048] Step S143: When the target drying mode is the second drying mode, if the working temperature is greater than or equal to the first set temperature within the second time period, the cooling fan is started.

[0049] Step S144: If the difference between the working temperature and the initial temperature is less than the temperature threshold difference, then control the cooling fan to run at the first speed.

[0050] Step S145: If the difference between the working temperature and the initial temperature is greater than or equal to the temperature threshold difference, then control the cooling fan to run at the second speed, which is greater than the first speed.

[0051] Regarding steps S143, S144, and S145: When the target drying mode is the second drying mode, if the operating temperature is higher than the first set temperature within the second time period, the cooling fan will be activated. In the second drying mode, the initial temperature is between the first threshold and the second threshold, and includes both the first threshold and the second threshold. For example, the first threshold is 20°C, and the second threshold is 25°C. That is to say, the ambient temperature is between 20°C and 25°C. The ambient temperature is slightly high. At this time, the comparison between the operating temperature and the first set temperature can be used to determine whether to turn on the cooling fan. For example, the first set temperature is 60°C. If the operating temperature is greater than or equal to 60°C within the second time period, it indicates that the temperature difference between the ambient temperature and the temperature inside the dryer is large and lasts for a long time, which poses a risk of condensation. Therefore, the cooling fan is turned on to cool down the air duct until the operating temperature in the duct is detected to be lower than the first set temperature, at which point the cooling fan is turned off.

[0052] The rotational speed of the cooling fan can be determined based on the difference between the operating temperature and the initial temperature.

[0053] For example, if the difference between the operating temperature and the initial temperature is less than the temperature threshold difference, the cooling fan is controlled to run at the first speed. It should be noted that the temperature threshold difference can be 37°C. When the difference between the operating temperature and the initial temperature is less than 37°C, it indicates that the system temperature is not very high. Therefore, using a lower speed (first speed) is sufficient, which can balance energy saving and cooling effect.

[0054] For example, if the difference between the operating temperature and the initial temperature is greater than or equal to the temperature threshold difference, the cooling fan is controlled to operate at a second speed, which is greater than the first speed. That is to say, if the difference between the operating temperature and the initial temperature is greater than or equal to 37°C, it indicates that the system temperature is high and a high-speed cooling fan is needed for rapid heat dissipation to reduce the risk of condensation.

[0055] Step S146: When the target drying mode is the third drying mode, start the cooling fan at the same time as starting the compressor, and control the cooling fan to run at the first speed.

[0056] Step S147: During the drying process, if the working temperature is greater than or equal to the first set temperature within the third time period, and the difference between the working temperature and the initial temperature is greater than or equal to the temperature threshold difference, then control the cooling fan to run at the second speed, which is greater than the first speed.

[0057] Regarding steps S146 and S147: When the target drying mode is the third drying mode, the ambient temperature is greater than 25°C, which means that the ambient temperature is high. If the humidity is also high, the risk of condensation is greater. Therefore, the cooling fan is started at the same time as the compressor, and the cooling fan is controlled to run at the first speed. During this process, the cooling fan can also be run with an on-off ratio of 60 seconds and 40 seconds until the program ends.

[0058] During the drying process, if the operating temperature is greater than or equal to the first set temperature (e.g., 60°C) within the third time period, and the difference between the operating temperature and the initial temperature is greater than or equal to a temperature threshold difference (e.g., 37°C), then the cooling fan is controlled to operate at a second speed, which is greater than the first speed. It is understandable that when the operating temperature remains high, rapid system cooling is necessary to reduce the temperature difference with the ambient temperature, thereby reducing condensation.

[0059] The steps described above are not the entire drying process; rather, they represent preliminary drying. After these steps are completed, a full timed drying cycle can be performed to completely dry the garments. Please refer to [link / reference]. Figure 4 As shown, Figure 4 This is a fourth flowchart illustrating the control method for a clothes dryer provided in an embodiment of this application. In one embodiment, after step S140, which involves controlling the cooling fan to operate based on the target drying mode, operating temperature, and initial temperature, the control method for the clothes dryer further includes: Step S150: Obtain the humidity of the clothes inside the inner drum.

[0060] Step S160: When the humidity of the clothes is less than or equal to the humidity threshold, run the first drying time in timed drying mode.

[0061] In the aforementioned drying modes involving cooling fans, the primary purpose is to reduce condensation, but the clothes may not necessarily be completely dried. Therefore, after the target drying mode has finished, the humidity level of the clothes inside the drum can be measured to determine whether the clothes have been dried.

[0062] For example, when the humidity of the clothes is less than or equal to the humidity threshold, the first drying time is run in timed drying mode, at which point the clothes are dried and the drying process ends.

[0063] For example, if the humidity of the clothes is greater than the humidity threshold, the drying in the target drying mode described above will continue until the humidity of the clothes is less than or equal to the humidity threshold, and then the timed drying mode will run for the first drying time.

[0064] The control method for a clothes dryer provided in this application uses the initial temperature inside the air duct as the ambient temperature and compares it with the operating temperature as the criterion for starting the cooling fan. The operation of the cooling fan is integrated into the drying process. By utilizing the existing components of the dryer, condensation caused by excessive temperature differences between the dryer's interior and the ambient environment can be reduced. This reduces the risk of electrical component failure due to condensation buildup, thereby improving the user experience. Furthermore, the operation of the cooling fan is dynamically adjusted based on the operating temperature and the initial temperature, ensuring that the cooling fan's operation is adapted to the overall system state, reducing both energy loss and condensation generation.

[0065] To facilitate better implementation of the control method for the clothes dryer according to the embodiments of this application, this application also provides a control device for the clothes dryer. The clothes dryer includes an inner drum, a compressor, an air duct, and a cooling fan. The inner drum is used to hold clothes and can be in the form of a roller drum, thus the clothes dryer can be a roller drum type. The compressor is one of the main components in the clothes dryer that performs the drying function. The compressor can be part of a heat pump system. The compressor is used to exchange heat with the inner drum through the air duct, thereby continuously expelling moisture from the clothes to dry them. The cooling fan is used to cool the heat pump system to prevent overheating, or in other words, the cooling fan is used to blow the heat generated by the compressor during operation to the outside of the clothes dryer to cool the compressor. Please refer to [link to relevant documentation]. Figure 5 As shown, Figure 5 This is a structural block diagram of the control device for a clothes dryer provided in an embodiment of this application. The control device 400 for the clothes dryer includes a first acquisition unit 410, a determination unit 420, a second acquisition unit 430, and a control unit 440.

[0066] The first acquisition unit 410 is used to acquire the initial temperature inside the air duct when the compressor is not started.

[0067] The determining unit 420 is used to determine the target drying mode from multiple drying modes based on the temperature range into which the initial temperature falls, with each temperature range corresponding to a drying mode.

[0068] The second acquisition unit 430 is used to start the compressor and acquire the working temperature inside the air duct. The control unit 440 is used to control the operation of the cooling fan according to the target drying mode, operating temperature and initial temperature.

[0069] All of the above technical solutions can be combined in any way to form optional embodiments of this application, and will not be described in detail here.

[0070] In the control device 400 for the dryer provided in this application embodiment, the initial temperature inside the air duct is used as the ambient temperature and compared with the working temperature as the judgment criterion for starting the cooling fan. The operation of the cooling fan is integrated into the drying program. By utilizing the original components of the dryer, the condensation caused by the large temperature difference between the inside of the dryer and the ambient temperature can be reduced. This can reduce problems such as electrical component failure caused by condensation accumulation, thereby improving the user experience.

[0071] Accordingly, this application also provides a clothes dryer (not shown in the figure), which includes an inner drum, a compressor, an air duct, and a cooling fan. The inner drum is used to hold clothes and can be in the form of a roller, thus the clothes dryer can be a roller-type clothes dryer. The compressor is one of the main components in the clothes dryer that performs the drying function. The compressor can be part of a heat pump system. The compressor is used to exchange heat with the inner drum through the air duct, thereby continuously expelling moisture from the clothes to dry them. The cooling fan is used to cool the heat pump system to prevent overheating, or in other words, the cooling fan is used to blow the heat generated by the compressor during operation to the outside of the clothes dryer to cool the compressor. Of course, the clothes dryer may also include components such as a display panel, a cabinet, and a door, which will not be described in detail here.

[0072] Please see Figure 6 As shown, Figure 6 This is a structural block diagram of a clothes dryer provided in an embodiment of this application. The clothes dryer 500 may further include a processor 509 with one or more processing cores, a memory 510 with one or more computer-readable storage media, and a computer program stored on the memory 510 and executable on the processor 509.

Those skilled in the art will understand that the structure of the clothes dryer 500 shown in the figure does not constitute a limitation on the clothes dryer, and it may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0073] The processor 509 is the control center of the dryer 500. It connects various parts of the dryer through various interfaces and lines.
