[0115] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0116] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0117] In the following description, the terms "first, second, third" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0118] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0119] In related technologies, the wrinkle-removing function of dryers works by using the dryer's heating and the tumbling of the drum to fluff up clothes. However, due to the prolonged compression of the clothes, wrinkles are difficult to completely remove, and new wrinkles are often created due to the compression itself. For example, shirts or T-shirts are very prone to wrinkling due to compression. Currently, there are methods that introduce steam for wrinkle removal. However, this simply adds steam to the clothes for steam wrinkle removal without changing the original drying process of the dryer. The clothes are still compressed, creating new wrinkles, resulting in poor wrinkle removal.

[0120] Based on this, embodiments of this application provide a drying device and its control method, apparatus, storage medium, and program product, which have excellent wrinkle removal effects.

[0121] The control method of the drying equipment provided in the embodiments of this application will be described below.

[0122] See Figure 1 , Figure 1 This is an optional structural diagram of the drying equipment provided in this application embodiment. The drying equipment includes a first circulation loop L10, a first drying module 110, an object receiving device 120, and a steam generator (not shown). At least a portion of the first drying module 110 and the object receiving device 120 are located on the first circulation loop, and the steam generator is connected to the first circulation loop L10. See also... Figure 2 , Figure 2 This is an optional flowchart illustrating a control method for a drying device provided in an embodiment of this application. The method includes:

[0123] Step 201: Control the first drying module to drive the air circulation in the first circulation loop and heat the air in the first circulation loop with the first power.

[0124] Step 202: When the gas temperature of the air flowing into the object containing device reaches a temperature threshold, the first power is adjusted to the second power, where the second power is less than the first power.

[0125] Step 203: Control the steam generator to produce steam to supply the first circulation loop;

[0126] Step 204: After the steam generator has generated steam for a period of time that reaches a first time threshold, control the steam generator to stop generating steam.

[0127] In actual implementation, the drying equipment is equipped with a controller (not shown) to implement the control method of the drying equipment provided in this application embodiment. The drying equipment is a dryer or a washer-dryer combo. Here, the controller can be, for example, a microcontroller unit (MCU). The controller is connected to other components within the drying equipment to communicate with and control each component. Specifically, the controller can be connected to the first drying module 110, the object receiving device 120, and the steam generator. Here, the object receiving device 120 is used to receive objects to be dried, such as clothing. The object receiving device 120 can be a cylindrical structure, which is disposed on the first circulation loop L10 and is part of the first circulation loop L10. Air flows through the object receiving device 120 when flowing in the first circulation loop L10. The first drying module 110 can drive the air to circulate in the first circulation loop L10 and can heat the air in the first circulation loop L10. The steam generator is connected to the first circulation loop L10 and can supply steam to the first circulation loop L10. By supplying steam to the first circulation loop L10, steam can be introduced into the object holding device 120 to steam-remove wrinkles from the clothes inside the object holding device 120.

[0128] In some embodiments, controlling the steam generator to produce steam for supplying the first circulation loop includes: controlling the steam generator to produce steam for supplying steam to an object receiving device located in the first circulation loop. In actual implementation, the steam generator may be specifically located near the object receiving device 120 to supply steam to the object receiving device 120.

[0129] In some embodiments, the first drying module includes a condenser located on the first circulation loop, the condenser being used to heat the air within the first circulation loop. See also Figure 1 The first drying module 110 may include a condenser 111 and a first evaporator 112 disposed in the refrigerant circulation loop L20. In one embodiment, the refrigerant circulation loop L20 is further provided with a compressor 113 and a throttle 114. The compressor 113 can drive the refrigerant to flow along the refrigerant circulation loop L20; when the refrigerant passes through the condenser 111, it releases heat, and the condenser 111 can use the heat released by the refrigerant to heat the air in the first circulation loop L10; when the refrigerant passes through the first evaporator 112, it absorbs heat, and the first evaporator 112 can use the heat absorbed by the refrigerant to cool the air in the first circulation loop L10, so that the water vapor in the air is condensed and removed.

[0130] In this embodiment, step 201 is the preheating stage. In step 201, the controller controls the first drying module 110 to drive the air circulation within the first circulation loop L10 and heat the air within the first circulation loop L10 with a first power. Specifically, the controller activates the components of the first drying module 110 to operate, driving the air circulation within the first circulation loop L10 with the first power and releasing heat through a refrigerant to heat the air, thereby preheating the air within the first circulation loop L10. Here, the first power can be a relatively large power, for example, the maximum power that the first drying module 110 can achieve within a safe range. By driving the air circulation with a larger power, the air within the first circulation loop L10 can achieve a faster temperature rise.

[0131] Here, the primary power is generated by a component in the drying module 110 capable of driving air. See also: [link to embodiments]. Figure 3 , Figure 3 This is an optional structural schematic diagram of the drying equipment provided in the embodiments of this application. The first drying module 110 further includes a first fan 115 located on the first circulation loop L10. In step 201, controlling the first drying module to drive the air circulation flow in the first circulation loop with a first power includes: controlling the first fan to operate at a first speed.

[0132] Here, the first fan 115 can be a circulating fan, used to provide power to drive the air circulation within the first circulation loop L10. In one embodiment, the first power can be generated when the first fan 115 operates at a first rotational speed. Here, the first rotational speed can be the maximum rotational speed that the first fan can reach within a safe range. In one embodiment, the first rotational speed is 3000-3500 rpm. In some embodiments, the number of first fans 115 can also be multiple, used to jointly provide the first power. Those skilled in the art can configure the components providing the first power according to actual needs, and this application embodiment does not specifically limit this.

[0133] In step 201, when the gas temperature of the air flowing into the object receiving device reaches a temperature threshold, the first power is adjusted to the second power. In actual implementation, a temperature sensor can be installed at the air inlet of the object receiving device to detect the gas temperature of the air flowing into the object receiving device 120. Here, the gas temperature of the air flowing into the object receiving device 120 can be the inlet temperature. The controller can acquire the temperature detected by the temperature sensor in real time. If the acquired temperature reaches the temperature threshold, the first power is adjusted to the second power. The temperature threshold can be 60-70℃. Here, the second power is less than the first power. Specifically, the second power can be a range that allows the clothes to be scattered in the object receiving device without being blown to the inner wall of the object receiving device. By reducing the power, the airflow speed is reduced. In the subsequent steam generation stage, a lower wind speed can be used to remove wrinkles from the clothes in conjunction with the steam, avoiding excessively high wind speeds that would blow the clothes to the inner wall of the object receiving device and cause new wrinkles.

[0134] In some embodiments, see Figure 3 The second power source can also be provided by the first fan 115. Specifically, adjusting the first power source to the second power source includes: adjusting the rotational speed of the first fan from the first rotational speed to a second rotational speed, wherein the second rotational speed is less than the first rotational speed.

[0135] In practical implementation, the first power is adjusted to the second power by changing the rotational speed of the first fan 115 from the first rotational speed to the second rotational speed. Here, the second rotational speed is less than the first rotational speed. In some embodiments, the second rotational speed is 0-1200 rpm. Specifically, in one embodiment, the second rotational speed is 1000 rpm. The second rotational speed ensures that the wind speed in the first circulation loop L10 is maintained at a level that blows the clothes into a scattered state, while preventing them from being blown into close contact with the inner wall of the object receiving device.

[0136] In step 203, the steam generator is controlled to produce steam to supply the object holding device 115. In actual implementation, after adjusting the first power to the second power, that is, after reducing the wind speed in the first circulation loop L10, steam is supplied to the object holding device 115 through the steam generator to steam-remove wrinkles from the clothes inside the object holding device 115. Here, the low wind speed after adjusting the power allows the clothes to be in a scattered state, so that the contact area with the steam is large for good wrinkle removal, while preventing them from being blown to the inner wall and creating new wrinkles.

[0137] In step 204, after the steam generator has generated steam for a first time threshold, the steam generator 115 is controlled to stop generating steam. The first time threshold is a preferred range that allows for effective steam wrinkle removal of clothing. In one embodiment, the first time threshold is 15-20 minutes.

[0138] In one embodiment, the object-containing device 120 has a cylindrical structure that can rotate within the drying equipment. In actual implementation, the object-containing device 120 can rotate continuously during operation. The rotation pattern can be, for example, rotating in a first direction for a first duration and then stopping, then rotating in a second direction for a second duration after stopping for a second duration and then stopping again, followed by a cycle of stopping for a second duration and then rotating in the first direction for the first duration. Here, the first duration is, for example, 5–10 minutes, the second duration is 5–10 seconds, and the third duration is 5–10 minutes.

[0139] For example, see Figure 4 , Figure 4 This is an optional schematic diagram of a garment wrinkle sample provided in an embodiment of this application. The method provided in this embodiment can achieve a garment wrinkle level of SA-3 or higher, that is... Figure 4 The fold grades corresponding to SA-3, SA-3.5, SA-4 and SA-5 are shown.

[0140] In this embodiment, the first drying module is controlled to drive the air circulation in the first circulation loop and heat the air in the first circulation loop with a first power. When the gas temperature of the air flowing into the object containing device reaches a temperature threshold, the first power is adjusted to a second power, which is less than the first power. Then, the steam generator is controlled to generate steam to supply the object containing device. After the steam generator generates steam for a period of time that reaches a first time threshold, the steam generator is controlled to stop generating steam. The first power quickly raises the air temperature, providing a high-temperature environment for better steam wrinkle removal. Then, the first power is reduced to the second power, so that a low wind speed is maintained during steam generation, avoiding excessive wind speed from squeezing the clothes and creating new wrinkles, thereby achieving a good wrinkle removal effect.

[0141] In some embodiments, when the gas temperature of the air flowing into the object receiving device reaches a temperature threshold, the method further includes: stopping the heating of the air in the first circulation loop.

[0142] In practical implementation, in step 202, if the gas temperature of the air flowing into the object containing device reaches a temperature threshold, heating of the air in the first circulation loop L10 is also stopped. Specifically, other components in the first drying module 110, except for the component that provides the power to drive the airflow, can be controlled to stop working. For example, only the first fan 115 can be kept running while other components in the first drying module 110 are turned off to stop heating the air. By turning off the components in the first drying module 110 other than the first fan 115 to stop heating the air, the first evaporator 112 in the first drying module 110 can be prevented from dehumidifying the air in the first circulation loop L10, thereby reducing the air humidity and affecting the steam wrinkle removal efficiency.

[0143] In some embodiments, after the steam generator generates steam for a first time threshold, the method further includes controlling the first drying module to reheat the air in the first circulation loop.

[0144] In actual implementation, after the steam wrinkle removal stage is completed, the air in the first circulation loop L10 is reheated to enter the drying stage, so as to dry the clothes in the object holding device 115 with hot air.

[0145] In some embodiments, after the first drying module reheats the air in the first circulation loop, the method further includes: stopping the heating of the air in the first circulation loop when the heating time for reheating the air in the first circulation loop reaches a second time threshold or the humidity of the air in the first circulation loop is less than or equal to a humidity threshold.

[0146] In practice, heating of the air in the first circulation loop can be stopped after the drying stop condition is met, thus completing the drying of the clothes. Here, the drying stop condition is that the heating time for reheating the air in the first circulation loop reaches a second time threshold, or the humidity of the air in the first circulation loop is less than or equal to a humidity threshold. In one embodiment, the second time threshold is 15-25 minutes. The humidity threshold can be a small value that indicates the clothes in the object containing device 120 have been dried when the humidity reaches this value. In one embodiment, the humidity threshold is 10-25% RH.

[0147] It should be noted that stopping the heating of the air in the first circulation loop specifically includes controlling the components in the first drying module 110, except for the first fan 115, to stop working.

[0148] In some embodiments, the method further includes stopping the operation of the first drying module when the heating of the air in the first circulation loop is stopped for a third time threshold.

[0149] In practical implementation, after the drying stage ends, the first drying module 110 stops heating the air in the first circulation loop, but continues to maintain the air circulation flow in the first circulation loop L10 driven by the second power, that is, to maintain the flow of cold air in the first circulation loop L10 to cool the clothes in the object holding device 120. Specifically, while the components in the first drying module 110 other than the first fan 115 stop working, the first fan 115 continues to operate at the second speed. In practical implementation, the operation of the first drying module 110 can be stopped when the cooling process reaches a third time threshold, so as to stop the air circulation in the first circulation loop L10. Specifically, the operation of the first fan 115 is stopped to end the cooling process. In one embodiment, the end of the cooling process also indicates that the drying equipment stops operating.

[0150] In some embodiments, a heater is further provided in the first circulation loop L10, and the method further includes: controlling the first drying module to heat the air in the first circulation loop while controlling the heater to heat the air in the first circulation loop.

[0151] In actual implementation, a heater is also provided in the first circulation loop L10. In step 201, while the air is heated by the first drying module 110, the heater is also used for auxiliary heating to improve heating efficiency and quickly raise the air temperature. In some embodiments, during the drying stage after the steam wrinkle removal stage, the heater can also be activated for auxiliary heating while the air is heated by the first drying module 110 to improve drying efficiency.

[0152] In some embodiments, see Figure 5 , Figure 5 This is an optional structural schematic diagram of the drying equipment provided in this application embodiment. The drying equipment further includes a second drying module 130, which includes a moisture absorption and dehumidification component 131 located on the first circulation loop L10. After the target conditions are met, the method further includes: controlling the second drying module to start, so as to use the moisture absorption and dehumidification component to dehumidify the air in the first circulation loop.

[0153] In actual implementation, the second drying module 130 includes a moisture absorption and dehumidification component 131 and a regeneration device 132. The moisture absorption and dehumidification component 131 can absorb moisture from the air, while the regeneration device 132 is used to remove the moisture absorbed by the moisture absorption and dehumidification component 131, thereby regenerating the component. Here, the regeneration device 132 may include a second evaporator. In step 204, after the target conditions are met, the controller also controls the second drying module 130 to start, so as to use the moisture absorption and dehumidification component 131 to dehumidify the air in the first circulation loop L10, thereby improving the drying efficiency. Here, the start-up of the second drying module 130 includes at least the start-up of the moisture absorption and dehumidification component 131. In one embodiment, the moisture absorption and dehumidification assembly 131 may include a moisture absorption turntable 1311. A controller can activate a motor that drives the turntable 1311 to rotate, causing the moisture-absorbing material within the turntable 1311 to move between the drying zone and the regeneration zone, thereby achieving air dehumidification and regeneration of the moisture absorption and dehumidification assembly 131. The moisture-absorbing material may be, for example, a molecular sieve. Furthermore, the moisture absorption and dehumidification assembly 131 can also adsorb impurities in the air, thus achieving the effect of removing mites and dust from clothing. In one embodiment, a shut-off valve 140 is provided on the inlet side of the regeneration device 132; the shut-off valve 140 is configured to open when the second drying module 130 is started and close when the second drying module 130 is turned off.

[0154] In some embodiments, see Figure 5 The moisture absorption and dehumidification component 131 is also equipped with an auxiliary heating device 1312. Before the gas temperature of the air flowing into the object containing device reaches the temperature threshold, the method includes: controlling the auxiliary heating device to start; when the gas temperature of the air flowing into the object containing device reaches the temperature threshold, the method further includes: controlling the auxiliary heating device to stop.

[0155] Here, the moisture absorption and desiccation assembly 131 may include a moisture absorption disc 1311 and an auxiliary heating device 1312. The auxiliary heating device 1312 is an electric auxiliary heater, such as a heating tube. It can be used to heat the moisture absorption disc 1311 to desorb the moisture adsorbed in the moisture absorption disc 1311, helping to regenerate the moisture absorption disc 1311. At the same time, it can also heat the air.

[0156] In practical implementation, before the air temperature flowing into the object receiving device reaches the temperature threshold, the auxiliary heating device 1312 can be activated to heat the air and increase the heating rate. Specifically, after starting the first fan 115, the second fan 133, and the moisture-absorbing turntable 1311, the auxiliary heating device 1312 can be activated after a preset time. Here, the preset time is, for example, 1 to 5 minutes. In this embodiment, the air is preheated by the first drying module and the second drying module together, which can quickly increase the overall temperature of the machine in a short time, thus creating a high-temperature environment for subsequent steam wrinkle removal.

[0157] In some embodiments, after the second drying module is started, the method further includes: controlling the auxiliary heating device to switch between starting and stopping to maintain the gas temperature of the air flowing into the object containing device within a target temperature range.

[0158] In actual implementation, after starting the first and second drying modules in step 204, the temperature of the air flowing into the object-containing device is controlled within the target temperature range by controlling the start and stop of the auxiliary heating device. This prevents excessively high temperatures from damaging the objects inside the device and avoids excessively low temperatures that would result in low drying efficiency. Here, the target temperature range can be, for example, 70–80°C. Specifically, the temperature is controlled by adjusting the start and stop times of the auxiliary heating device.

[0159] In some embodiments, controlling the auxiliary heating device to switch between starting and stopping to maintain the gas temperature of the air flowing into the object containing device within a target temperature range includes: when the auxiliary heating device is in the starting state, controlling the auxiliary heating device to stop if the gas temperature of the air flowing into the object containing device is greater than or equal to a first threshold; and when the auxiliary heating device is in the stopping state, controlling the auxiliary heating device to start if the gas temperature of the air flowing into the object containing device is less than or equal to a second threshold; wherein the second threshold is less than the first threshold.

[0160] In practical implementation, when the auxiliary heating device is in the activated state, if the temperature sensor detects that the gas temperature of the air flowing into the object containing the container is greater than or equal to a first threshold, the auxiliary heating device is controlled to shut down to cool the air. Conversely, when the detected gas temperature is less than or equal to a second threshold, the auxiliary heating device is controlled to start to heat the air, thereby maintaining the gas temperature between the second and first thresholds. In some embodiments, 70°C ≤ second threshold < first threshold ≤ 80°C.

[0161] In some embodiments, see Figure 5The drying equipment further includes a second circulation loop L30, and the second drying module 130 is located on the second circulation loop L30. The method further includes: while controlling the first drying module to heat the air in the first circulation loop, controlling the second drying module to promote the air circulation in the second circulation loop; when the gas temperature of the air flowing into the object containing device reaches a temperature threshold, the method further includes: controlling the second drying module to stop promoting the air circulation in the second circulation loop.

[0162] Here, the second circulation loop L30 is equipped with at least a moisture absorption and desiccation assembly 131 and a regeneration device 132. In actual implementation, step 201 also involves controlling the second drying module 130 to drive the air circulation within the second circulation loop L30. Here, the second drying module 130 is equipped with components capable of driving the airflow within the second circulation loop L30. See also... Figure 6 , Figure 6 This is an optional structural schematic diagram of the drying equipment provided in this application embodiment. The second drying module 130 also includes a second fan 133. The second fan 133 is used to provide power to drive the air circulation within the second circulation loop L30. In actual implementation, the second fan 133 operates at a third rotational speed to drive the air circulation within the second circulation loop L30. Here, the third rotational speed can be a large value to increase the air heating rate. In one embodiment, the third rotational speed can be the highest rotational speed that the second fan 133 can achieve within a safe range.

[0163] In step 202, when the temperature of the air flowing into the object receiving device 120 reaches the temperature threshold, the second drying module 130 is also controlled to stop pushing the airflow within the second circulation loop L30. Specifically, the second drying module 130 is controlled to shut down, so that all components of the second drying module 130 stop working. This is to prevent the second drying module 130 from carrying away moisture from the air when it is in operation during the subsequent steam generation stage, thus affecting the steam wrinkle removal effect.

[0164] In some embodiments, before controlling the first drying module to drive the air circulation flow in the first circulation loop with the first power and to heat the air in the first circulation loop, the method further includes: controlling the steam generator to stop generating steam after controlling the steam generator to run for a first working time.

[0165] In practice, before step 201, i.e., before the preheating stage, the first circulation loop is pre-humidified by starting a steam generator. After the pre-humidification process reaches a first working time, the steam generator is turned off to stop humidification. In one embodiment, the first working time is 1 minute. By performing a short pre-humidification process before heating the first circulation loop, the air humidity in the first circulation loop is increased to avoid damage to the components of the drying equipment caused by excessively dry hot air during the subsequent heating process.

[0166] In some embodiments, before controlling the steam generator to operate for a first operating time, the method further includes: draining the object containing device; and stopping the drainage process when a drainage stop condition is met.

[0167] In practice, before the pre-humidification process, the object-containing device is drained. Specifically, the drain pump of the drying equipment is activated to drain the clothes until the drainage stops. In some embodiments, the drainage stops when the water level in the object-containing device is less than or equal to a water level threshold, and the drainage process is performed for a second working period. That is, after the water level in the object-containing device drops to the water level threshold, the drainage process continues for a second working period and then stops. Here, the water level threshold is 0-1 mm. The second working period is 10 seconds.

[0168] In some embodiments, the object receiving device is provided with an openable and closable door, and before the object receiving device is drained, the method further includes locking the door in response to a start command.

[0169] In practice, in response to the start command, the door of the object receiving device is locked to prevent clothes from being thrown out during subsequent processing as the drying equipment operates. Here, the start command can be generated by the user by triggering the corresponding button on the drying equipment to start the main program of the drying equipment.
