Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and specifically provides a control method for clothing processing equipment and clothing processing equipment. Background Technology

[0002] In modern family life, washer-dryer combos, as a type of home appliance that integrates washing and drying functions, are widely popular among consumers due to their convenience and efficiency. Water condensation technology, one of the commonly used drying technologies in washer-dryer combos, transfers heat and moisture from humid air to condensate water through condenser pipes, thereby achieving the drying process for clothes. However, existing water condensation washer-dryer combos still have some design and application issues that urgently need to be addressed.

[0003] Traditional water-cooling methods typically involve a condenser pipe running between the outer cylinder outlet and the fan inlet, through which cooling water is circulated. While this design achieves some degree of condensation of hot and humid air, the condenser pipe not only occupies valuable internal space, resulting in a larger overall machine size and hindering miniaturization and efficient use of home space, but also, due to the relatively small heat exchange area of ​​the condenser pipe, condensation efficiency is often low, affecting drying performance and energy consumption.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem of low drying efficiency in existing clothing processing equipment.

[0006] In a first aspect, the present invention provides a control method for a garment processing device, the garment processing device comprising a housing and an outer cylinder, an inner cylinder assembly, and a drying device installed within the housing, the inner cylinder assembly being rotatably installed in the outer cylinder, the drying device having two ends respectively connected to the front end and rear end of the outer cylinder, the drying device being capable of supplying hot air to the inner cylinder assembly, and a nozzle being provided on the rear wall of the outer cylinder, the nozzle being capable of spraying cooling water toward the rear of the inner cylinder assembly to keep the rear of the inner cylinder assembly at a low temperature, the control method comprising:

[0007] During the drying process of the garment processing equipment, the nozzles intermittently spray cooling water toward the rear of the inner drum assembly.

[0008] In the preferred embodiment of the above control method, the step of "intermittently spraying cooling water towards the rear of the inner cylinder assembly" specifically includes:

[0009] The nozzle sprays cooling water for time T1 onto the rear of the inner cylinder assembly, and then stops for time T2.

[0010] In a preferred embodiment of the above control method, the control method further includes:

[0011] Obtain the weight of the clothing in the inner tube assembly;

[0012] The specific values ​​of T1 and T2 are determined based on the weight of the garment.

[0013] In the preferred embodiment of the above control method, the step of "intermittently spraying cooling water towards the rear of the inner cylinder assembly" specifically includes:

[0014] Obtain the temperature of the rear part of the inner cylinder assembly;

[0015] Compare the temperature with the preset temperature;

[0016] If the temperature is lower than the preset temperature, the nozzle will stop spraying cooling water onto the rear of the inner cylinder assembly.

[0017] If the temperature is not less than the preset temperature, then the nozzle sprays cooling water toward the rear of the inner cylinder assembly.

[0018] In a preferred embodiment of the above control method, the control method further includes:

[0019] When the humidity level of the clothes in the inner drum assembly drops to a preset humidity level, the nozzle stops spraying cooling water onto the rear of the inner drum assembly.

[0020] In a preferred embodiment of the above control method, the control method further includes:

[0021] When the humidity of the clothes in the inner drum assembly drops to the preset humidity value, the drying device continues to run for time T3 and then stops.

[0022] In the preferred embodiment of the above control method, the inner cylinder assembly includes a cylinder body and a condenser plate. The rear wall of the cylinder body has multiple through holes. The condenser plate is located between the rear wall of the outer cylinder and the rear wall of the cylinder body. The condenser plate is fixedly connected to the cylinder body and has a gap between it and the rear wall of the cylinder body. The nozzle can spray cooling water toward the condenser plate.

[0023] In the preferred embodiment of the above control method, the cross-section of the condenser plate is wavy.

[0024] In the preferred embodiment of the above control method, multiple nozzles are provided, the multiple nozzles are spaced apart, and the water outlet of the nozzle is fan-shaped.

[0025] In a second aspect, the present invention also provides a garment processing apparatus, the garment processing apparatus including a controller configured to perform the control method described above.

[0026] Those skilled in the art will understand that the present invention provides a control method for a garment processing device. The garment processing device includes a housing and an outer cylinder, an inner cylinder assembly, and a drying device installed inside the housing. The inner cylinder assembly is rotatably installed in the outer cylinder. The two ends of the drying device are respectively connected to the front end and the rear end of the outer cylinder. The drying device can deliver hot air to the inner cylinder assembly. A nozzle is provided on the rear wall of the outer cylinder. The nozzle can spray cooling water toward the rear of the inner cylinder assembly to keep the rear of the inner cylinder assembly at a low temperature. The control method includes: during the drying process of the garment processing device, the nozzle intermittently sprays cooling water toward the rear of the inner cylinder assembly. By adopting the above technical solution, the present invention can improve the drying efficiency of clothes. Specifically, compared with the prior art, the present invention eliminates the condenser pipe and directly uses the rear of the inner drum assembly as the condenser structure. The rear of the inner drum assembly has a large area, thereby providing a larger condensation area and improving the drying efficiency of the equipment. In addition, during the drying mode, the nozzle does not continuously spray cooling water towards the rear of the inner drum assembly, but intermittently. This setting can effectively avoid the situation where the drying efficiency is affected by the internal temperature of the inner drum assembly being too low, thereby more effectively improving the drying efficiency of the equipment.

[0027] Furthermore, in this invention, the step of "intermittently spraying cooling water towards the rear of the inner drum assembly" specifically includes: spraying cooling water towards the rear of the inner drum assembly for time T1 and then stopping for time T2. By setting specific spraying time T1 and stopping time T2, precise control of the cooling water spraying process can be achieved, thereby optimizing heat exchange efficiency and drying effect. Moreover, by adjusting the values ​​of T1 and T2, different drying needs and clothing types can be accommodated, providing a more flexible and personalized drying solution.

[0028] Furthermore, the control method of the present invention further includes: when the humidity value of the clothes in the inner drum assembly decreases to a preset humidity value, the nozzle stops spraying cooling water onto the rear of the inner drum assembly. When the humidity value of the clothes decreases to the preset humidity value, it indicates that the clothes have completed the drying process and there is no need to further condense the air in the inner drum assembly. Therefore, the controller controls the nozzle to stop spraying cooling water onto the rear of the inner drum assembly, ensuring that the clothes are properly dried.

[0029] Furthermore, the control method of the present invention also includes: when the humidity value of the clothes in the inner drum assembly decreases to a preset humidity value, the drying device continues to run for a time T3 and then stops running. Since cooling water will remain at the rear of the inner drum assembly after the nozzle stops spraying cooling water, stopping the drying device after running for a time T3 can also evaporate this portion of cooling water, thereby preventing the clothes from being damp or dripping when taken out, and further improving the drying effect of the clothes.

[0030] Furthermore, the inner drum assembly includes a drum body and a condenser plate. Multiple through holes are provided on the rear wall of the drum body. The condenser plate is located between the rear wall of the outer drum and the rear wall of the drum body. The condenser plate is fixedly connected to the drum body and has a gap between it and the rear wall of the drum body. The nozzle can spray cooling water towards the condenser plate. With this structural design, when the humid and hot air in the drum body comes into contact with the condenser plate through the through holes on the rear wall of the drum body, the water in the drum body will quickly condense on the condenser plate, realizing the condensation process and transforming the humid and hot air in the drum body into dry air, thereby further accelerating the drying efficiency of clothes.

[0040] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. For example, although the following embodiments are described in conjunction with a washer-dryer combo, the garment processing equipment provided by the present invention is equally applicable to other products that need to solve the problem of low drying efficiency.

[0041] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] As noted in the background section, existing garment processing equipment suffers from low drying efficiency. This invention provides a control method and garment processing equipment for garment processing, aiming to effectively solve the problem of low drying efficiency by controlling the water condensation method during the garment drying process.

[0043] Example 1

[0044] First refer to Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the garment processing device of the present invention; Figure 2 This is a cross-sectional view of the garment processing device of the present invention.

[0045] like Figure 1 and Figure 2 As shown, the present invention provides a garment processing device, which includes a housing and an outer cylinder 1, an inner cylinder assembly 2 and a drying device 3 installed inside the housing. The inner cylinder assembly 2 is rotatably installed in the outer cylinder 1. The two ends of the drying device 3 are respectively connected to the front end and the rear end of the outer cylinder 1. The drying device 3 can deliver hot air to the inner cylinder assembly 2. A nozzle 11 is provided on the rear wall of the outer cylinder 1. The nozzle 11 can spray cooling water toward the rear of the inner cylinder assembly 2 so that the rear of the inner cylinder assembly 2 is in a low temperature state.

[0046] In this invention, the housing serves as the external support and protection structure for the entire garment processing equipment. The housing not only provides the necessary strength and stability but also ensures the safety and aesthetics of the equipment during operation.

[0047] The outer cylinder 1 is the external container of the inner cylinder assembly 2. It is fixedly installed inside the box and provides stable support for the rotation of the inner cylinder assembly 2. In addition, the outer cylinder 1 has good sealing and heat insulation properties to ensure that the hot air of the drying device 3 can be efficiently transferred to the inner cylinder assembly 2 while preventing heat loss.

[0048] The inner drum assembly 2 is a key component that is rotatably installed in the outer drum 1, and it directly supports the clothes to be processed. The rotation of the inner drum assembly 2 helps to evenly distribute and effectively process the clothes during the washing and spin-drying process, and also helps to evenly blow hot air onto the surface of the clothes during the drying process, thereby humidifying the clothes.

[0049] The drying device 3 is located between the front and rear ends of the outer drum 1 and is connected to the inside of the outer drum 1. The drying device 3 can deliver hot air to the inner drum assembly 2. The hot air flows between the clothes and removes the moisture from the clothes, thereby achieving rapid drying of the clothes.

[0050] For example, such as Figure 2 As shown, the drying device 3 includes a drying air duct 31, a heater 32, and a fan 33. The heater 32 and the fan 33 are installed in the drying air duct 31. The air outlet of the drying air duct 31 is connected to the front end of the outer cylinder 1, and the air inlet of the drying air duct 31 is connected to the rear end of the outer cylinder 1. The heater 32 can heat the air from the air inlet of the drying air duct 31, and the fan 33 can transport the heated air to the outer cylinder 1 through the air outlet of the drying air duct 31.

[0051] The drying duct 31 is responsible for guiding the airflow and ensuring that the air is heated during the flow. The heater 32 is installed inside the drying duct 31 to heat the air during the flow.

[0052] When the drying device 3 is started, the heater 32 begins to work, heating the air from the air inlet of the drying duct 31. The heated air flows inside the drying duct 31 and is eventually sent into the outer cylinder 1 through the air outlet. Inside the outer cylinder 1, the hot air exchanges heat with the clothes, removing moisture from the clothes, thereby achieving the drying effect.

[0053] This invention features a nozzle 11 mounted on the rear wall of the outer cylinder 1, which sprays cooling water towards the rear of the inner cylinder assembly 2. This design replaces the traditional condenser piping, directly spraying cooling water towards the rear of the inner cylinder. The sprayed cooling water keeps the rear of the inner cylinder assembly 2 at a low temperature, which helps accelerate the condensation process of the hot and humid air within the inner cylinder assembly 2, improving drying efficiency. Furthermore, directly spraying cooling water to the rear of the inner cylinder assembly 2 increases the heat exchange area, improving condensation efficiency and thus shortening drying time. Due to the increased drying efficiency, the machine consumes less energy and is more energy-efficient and environmentally friendly while achieving the same drying effect.

[0054] Furthermore, by setting the nozzle 11 on the rear wall of the outer cylinder 1, the present invention omits the traditional condenser piping, reduces the space occupied inside the machine, and makes the machine more compact and convenient for home use.

[0055] Preferably, such as Figure 2As shown, the inner cylinder assembly 2 includes a cylinder body 21 and a condenser plate 22. Multiple through holes 211 are provided on the rear wall of the cylinder body 21. The condenser plate 22 is located between the rear wall of the outer cylinder 1 and the rear wall of the cylinder body 21. The condenser plate 22 is fixedly connected to the cylinder body 21 and has a gap between it and the rear wall of the cylinder body 21. The nozzle 11 can spray cooling water toward the condenser plate 22.

[0056] The cylinder 21 serves as the main body of the inner cylinder assembly 2 and is used to load and rotate clothing. Multiple through holes 211 are formed on the rear wall of the cylinder 21, which allow hot and humid air to pass through the inside of the cylinder 21 and come into contact with the condenser plate 22.

[0057] A condenser plate 22 is disposed between the rear wall of the outer cylinder 1 and the rear wall of the cylinder 21, and is fixedly connected to the cylinder 21. A certain gap is maintained between the condenser plate 22 and the rear wall of the cylinder 21, which provides the necessary space for the spraying of cooling water and the condensation of humid and hot air.

[0058] The nozzle 11 can spray cooling water directly towards the condenser plate 22. When the cooling water comes into contact with the condenser plate 22, it will quickly absorb the heat on the condenser plate 22 and evaporate, thus keeping the condenser plate 22 at a low temperature. When the hot and humid air in the cylinder 21 comes into contact with the condenser plate 22 through the through hole 211 on the rear wall of the cylinder 21, the water in the hot and humid air will quickly condense on the condenser plate 22, realizing the condensation process and turning the hot and humid air into dry air, thereby accelerating the drying efficiency of clothes.

[0059] Furthermore, compared to traditional condenser piping, the condenser plate 22 has a larger condensation area, thereby increasing the contact area between the hot and humid air and the cooling water, making the condensation process more efficient. At the same time, the gap between the condenser plate 22 and the rear wall of the cylinder 21 ensures that the hot and humid air in the cylinder 21 can flow smoothly through and contact the condenser plate 22, further accelerating the condensation efficiency.

[0060] Therefore, by placing the condenser plate 22 between the outer cylinder 1 and the cylinder 21, and using the through hole 211 on the rear wall of the cylinder 21 for the exchange of hot and humid air, the present invention not only achieves a highly efficient condensation effect, but also optimizes the space utilization inside the machine.

[0061] Preferably, the cross-section of the condenser plate 22 is wavy.

[0062] The wavy cross-section design gives the condenser plate 22 a larger surface area, thus increasing the contact area with cooling water and humid, hot air. This helps improve condensation efficiency, because a larger surface area means more heat can be carried away quickly.

[0063] Furthermore, the wave-shaped structure guides the cooling water and humid air to form more complex flow paths on the condenser plate 22, increasing the heat exchange time. This design helps to make fuller use of the cooling capacity of the cooling water and improve heat exchange efficiency.

[0064] Preferably, multiple nozzles 11 are provided, with the multiple nozzles 11 arranged at intervals, and the water outlet of the nozzles 11 is fan-shaped.

[0065] To improve condensation efficiency and uniformity, the present invention provides multiple nozzles 11 on the rear wall of the outer cylinder 1. These nozzles 11 are evenly distributed at intervals to ensure that cooling water can uniformly cover the condenser plate 22.

[0066] The outlet of each nozzle 11 is designed in a fan shape. This shape not only helps to increase the contact area between the cooling water and the condenser plate 22, but also allows the cooling water to be distributed more evenly. The fan-shaped outlet allows the cooling water to form a fan-shaped spray when sprayed, covering a wider area. This helps to ensure that every point on the condenser plate 22 is adequately cooled, avoiding condensation blind spots, thereby improving condensation efficiency.

[0067] It should be noted that the nozzle 11 installed on the rear wall of the outer cylinder 1 can spray cooling water directly onto the rear wall of the cylinder 21 or onto the condenser plate 22.

[0068] When the nozzle 11 sprays cooling water directly onto the rear wall of the cylinder 21 (this design does not include a condenser plate 22), no through-hole 211 is provided on the rear wall of the cylinder 21. The cooling water keeps the rear wall of the cylinder 21 at a low temperature. When the humid and hot air inside the cylinder 21 comes into contact with the rear wall of the cylinder 21, the water in the cylinder 21 will quickly condense on the rear wall of the cylinder 21 and then flow into the outer cylinder 1 for discharge, thus achieving the condensation process.

[0069] When the nozzle 11 sprays cooling water onto the plate, a through hole 211 is opened on the rear wall of the cylinder 21. The cooling water keeps the condenser plate 22 at a low temperature. When the hot and humid air inside the cylinder 21 passes through the through hole 211 and comes into contact with the condenser plate 22, the water in the cylinder 21 will quickly condense on the condenser plate 22 and then flow into the outer cylinder 1 to be discharged, thus realizing the condensation process.

[0070] Furthermore, the present invention preferably provides a condenser plate 22 between the outer cylinder 1 and the cylinder body 21. Compared to directly spraying cooling water onto the rear wall of the cylinder body 21 through the nozzle 11, providing a condenser plate 22 between the outer cylinder 1 and the cylinder body 21 allows the cooling water to collect on the condenser plate instead of accumulating in the cylinder body 21, thereby avoiding the problem of cooling water dripping onto clothing and being repeatedly absorbed by the clothing. Of course, in other embodiments, depending on the actual usage scenario or cost control factors, the cooling water can be directly sprayed onto the rear wall of the cylinder body 21, or a condenser plate 22 can be provided between the outer cylinder 1 and the cylinder body 21 so that the cooling water is sprayed onto the condenser plate 22. The present invention does not specifically limit this.

[0071] Based on the clothing processing equipment described above, the present invention also provides a control method for the clothing processing equipment, the control method of the present invention comprising:

[0072] During the drying process of the garment processing equipment, the nozzle 11 intermittently sprays cooling water toward the rear of the inner drum assembly 2.

[0073] The nozzle 11 of this invention does not continuously spray cooling water toward the rear part of the inner cylinder assembly 2 (the rear wall of the cylinder 21 or the condenser plate 22), but sprays it intermittently. Intermittent spraying of cooling water can avoid the internal temperature of the cylinder 21 becoming too low due to the low temperature of the condenser plate 22, while ensuring effective heat exchange with the humid and hot air during each spray, thereby improving the overall heat exchange efficiency.

[0074] In addition, intermittent spraying helps to create a more uniform temperature distribution during the drying process, avoiding localized overheating or undercooling, thereby improving the uniformity and quality of clothing drying.

[0075] Preferably, such as Figure 3 As shown, the step of "intermittently spraying cooling water towards the rear of the inner cylinder assembly 2 from the nozzle 11" specifically includes:

[0076] After spraying cooling water into the rear of the inner cylinder assembly 2 for time T1, stop for time T2.

[0077] By setting specific spray time T1 and stop time T2, precise control of the cooling water spraying process can be achieved, thereby optimizing heat exchange efficiency and drying effect. Furthermore, by adjusting the values ​​of T1 and T2, different drying needs and clothing types can be accommodated, providing more flexible and personalized drying solutions.

[0078] Preferably, such as Figure 3 As shown, the control method of the present invention further includes:

[0079] Obtain the weight of the clothes in the inner tube assembly 2;

[0080] The specific values ​​of T1 and T2 are determined based on the weight of the clothing.

[0081] For example, the inner tube assembly 2 of the present invention is provided with a weight sensor, which can obtain the weight of the clothes in the inner tube assembly 2. In addition, the clothes processing device of the present invention is also provided with a controller, which is used to receive the data from the weight sensor and automatically adjust the specific values ​​of the spraying time T1 and the stop time T2 according to the detected weight of the clothes.

[0082] By detecting the weight of the clothes and adjusting T1 and T2 accordingly, a more personalized drying solution can be achieved, ensuring optimal drying results for clothes of different weights. For lighter clothes, the spray time T1 can be reduced and / or the stop time T2 can be increased to reduce energy consumption; for heavier clothes, the spray time T1 can be appropriately increased to improve condensation efficiency, ensuring drying results while still maintaining high efficiency and energy saving.

[0083] For example, when drying lighter garments (e.g., 1-3 kg), the humid air in the inner drum assembly 2 contains relatively little moisture, allowing for a shorter spray time (e.g., 10 seconds) and a longer stop time (e.g., 20 seconds) to allow the garments to gradually heat up and evaporate moisture. As the weight of the garments increases (e.g., 3-5 kg), the moisture in the humid air in the inner drum assembly 2 increases, allowing for a slightly longer spray time (e.g., 20 seconds) and a correspondingly shorter stop time (e.g., 15 seconds) to ensure that the moisture in the humid air condenses and precipitates out in time, maintaining drying efficiency. For heavier garments (e.g., 5-7 kg), a longer spray time (e.g., 30 seconds) is required to ensure that the water in the humid air is fully condensed and precipitated out, while the stop time can be shortened (e.g., 10 seconds) to maintain the drying speed.

[0084] Of course, in other embodiments, adjustments can be made according to the performance parameters of the device and the specific conditions of the clothing. The present invention does not limit the specific values ​​of T1 and T2.

[0085] Preferably, such as Figure 3 As shown, the control method of the present invention further includes:

[0086] When the humidity of the clothes in the inner drum assembly 2 drops to the preset humidity value, the nozzle 11 stops spraying cooling water onto the rear of the inner drum assembly 2.

[0087] For example, the inner drum assembly 2 of the present invention is provided with a temperature sensor to monitor the temperature at the rear of the inner drum assembly 2 in real time. The controller can receive data from the humidity sensor and compare it with a preset humidity value. When the humidity sensor detects that the humidity value of the clothes has dropped below the preset humidity value, it indicates that the clothes have completed the drying process and there is no need to condense the air in the inner drum assembly 2. Therefore, the controller controls the nozzle 11 to stop spraying cooling water onto the rear of the inner drum assembly 2.

[0088] For example, the preset humidity value in this invention is 20% to 30%.

[0089] A humidity range of 20% to 30% is suitable for a variety of clothing materials, including cotton, polyester, wool, and silk. These materials maintain an appropriate moisture content within this range, avoiding both excessive dampness and damage from over-drying. Furthermore, setting the preset humidity level within this range ensures that clothes are properly dried.

[0090] Of course, since different materials have different sensitivities to humidity, in other embodiments, users should fine-tune the preset humidity value according to the specific material of the clothing and drying requirements. This invention does not specifically limit the preset humidity value.

[0091] Preferably, such as Figure 3 As shown, the control method of the present invention further includes:

[0092] When the humidity of the clothes in the inner drum assembly 2 drops to the preset humidity value, the drying device 3 continues to run for time T3 and then stops.

[0093] Even though the humidity level of the clothes has been reduced to the preset value, some areas or thicker parts may still contain some moisture. By allowing the drying unit 3 to continue running for an additional time T3, it can be ensured that the moisture in these areas is also fully evaporated, resulting in a more even drying effect. In addition, since cooling water will remain at the rear of the inner drum assembly 2 after the nozzle 11 stops spraying cooling water, stopping the drying unit 3 after running for T3 time will also evaporate this cooling water, thus preventing the clothes from being damp or dripping when taken out, further improving the user's drying experience.

[0094] For example, T3 in this invention is specifically 5 to 10 minutes. This ensures that the cooling water remaining at the rear of the inner drum assembly 2 can be fully evaporated, while avoiding energy waste caused by excessively long drying times. In other embodiments, the user should set the T3 time reasonably according to the specific condition of the clothes and the prompts of the device's intelligent control system; this invention does not limit the specific time of T3.

[0095] Example 2

[0096] like Figure 4 As shown, the difference from Embodiment 1 is that the step of "intermittently spraying cooling water towards the rear of the inner cylinder assembly 2" specifically includes:

[0097] Obtain the temperature of the rear part of the inner cylinder assembly 2;

[0098] Compare the temperature with the preset temperature;

[0099] If the temperature is lower than the preset temperature, the nozzle 11 will stop spraying cooling water onto the rear of the inner cylinder assembly 2.

[0100] If the temperature is not lower than the preset temperature, the nozzle 11 will spray cooling water toward the rear of the inner cylinder assembly 2.

[0101] For example, the inner cylinder assembly 2 of the present invention is provided with a temperature sensor, which can monitor the temperature of the rear of the inner cylinder assembly 2 in real time. The controller can receive the data from the temperature sensor and compare it with a preset temperature threshold.

[0102] If the temperature at the rear of the inner drum assembly 2 is lower than the preset temperature threshold, it indicates that the current internal temperature of the inner drum assembly 2 is low. The temperature inside the inner drum assembly 2 needs to be increased to accelerate the drying process of the clothes. Therefore, there is no need to spray cooling water at the rear of the inner drum assembly 2 for condensation, to avoid the internal temperature of the inner drum assembly 2 being too low and unable to effectively dry the clothes. At this time, the controller causes the nozzle 11 to stop spraying cooling water at the rear of the inner drum assembly 2.

[0103] If the temperature at the rear of the inner drum assembly 2 is not lower than the preset temperature threshold, it indicates that the temperature inside the inner drum assembly 2 is still relatively high, and the clothes are being dried. In this state, the humid air in the inner drum assembly 2 contains a lot of moisture, so it is necessary to spray cooling water to condense and precipitate the moisture in the humid air in the inner drum assembly 2, thereby drying the hot air in the inner drum assembly 2 and accelerating the drying process. At this time, the controller directs the nozzle 11 to spray cooling water towards the rear of the inner drum assembly 2.

[0104] For example, the preset temperature threshold in this invention is 40℃~60℃.

[0105] The temperature range of 40℃ to 60℃ is suitable for various clothing materials, including cotton, polyester, and synthetic fibers. These materials can gradually heat up and evaporate moisture within this temperature range without being damaged by excessive heat. In addition, setting the preset temperature threshold within this range ensures that the nozzle 11 can spray cooling water to accelerate the drying process of the clothes when the temperature at the rear of the inner drum assembly 2 is not lower than this temperature.

[0106] While a temperature range of 40°C to 60°C is suitable for a variety of clothing materials, different materials have different sensitivities to temperature. Therefore, in other embodiments, the user can fine-tune the preset temperature threshold according to the specific material of the clothing and drying requirements. This invention does not specifically limit the preset temperature threshold.

[0107] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
