Description

Technical Field

[0001] The present invention relates to the technical field of clothing treatment, and particularly relates to a silent drying control method and a clothing treatment device. Background Art

[0002] With the rapid development of modern household appliance technology, clothing treatment devices such as washing machines and dryers have become indispensable electrical products in family life. These devices not only provide basic functions such as washing and drying, but also continuously incorporate innovative elements such as intelligence and personalization to meet the increasingly diverse needs of users. However, while pursuing high efficiency and convenience, the noise problem of clothing treatment devices during night operation has gradually become the focus of user attention.

[0003] Especially in urban life, due to the accelerated work rhythm of people, night has become the main time period for many users to handle clothes. However, traditional clothing treatment devices often generate relatively large noise when performing the drying function, which not only disturbs the rest and sleep of users, but may also cause unnecessary troubles to surrounding residents.

[0004] The noise problem of existing clothing treatment devices during the drying process has become an important factor restricting their further development and application. Although there have been some solutions and technologies to attempt to solve this problem, they still have the following deficiencies in terms of silent drying efficiency, intelligent control, and stop judgment logic:

[0005] 1: Severe noise interference: During the drying process of existing clothing treatment devices, due to factors such as the high-speed rotation of the fan, the large power of the heating device, and the impact of clothes in the inner barrel, the noise level is relatively high. This noise not only affects the user experience, but may also have a negative impact on the physical and mental health of users.

[0006] 2: The contradiction between drying efficiency and noise control: In order to reduce noise, some clothing treatment devices attempt to achieve this by reducing the fan speed and the power of the heating device. However, this approach often leads to a decrease in drying efficiency, prolongs the drying time, and thus increases the waiting time and energy consumption cost of users.

[0007] 3: Lack of intelligent silent drying control: Most existing clothing treatment devices adopt fixed drying modes and parameters and cannot be intelligently adjusted according to the actual needs of users and environmental conditions. This makes it impossible for users to obtain the best silent drying experience during use.

[0008] 4: Single stop judgment logic: Traditional clothing treatment devices often adopt a single stop judgment method during drying judgment, such as stopping only according to the sensor detecting that the clothes are dry or setting the longest drying time, etc. This single stop judgment logic may not be able to accurately judge the drying state of clothes, resulting in under-drying or over-drying.

[0009] Therefore, how to effectively reduce noise while ensuring drying efficiency has become an important issue that needs to be urgently addressed in the current field of clothing processing equipment technology. Summary of the invention

[0010] In view of this, the present invention proposes a silent drying control method and a clothing processing device, aiming to solve the noise problem generated by existing clothing processing equipment during the drying process, especially in occasions where a quiet environment is required, such as use at night or in homes with infants and the elderly. The traditional drying mode often generates loud noise, affecting the comfort and tranquility of the family.

[0011] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0012] A silent drying control method comprises the following steps:

[0013] S1: Determine whether to enter the silent drying program, if yes, execute S2; if not, execute S3;

[0014] S2: Adjust the fan speed V of the laundry processing equipment 静音 And heating device power W 静音 ;

[0015] S3: Fan speed V under normal drying conditions 正常 And heating device power W 正常 ;

[0016] Among them, V 静音 <V 正常 , W 静音 <W 正常 .

[0017] Furthermore, the heating device power W 静音 At least two heating tubes are included to form a two-stage heating device with a power of W 静音 , respectively W 静音1 , W 静音2 , where W 静音1 <W 静音2 In the silent drying program, select one or two heating tubes to work according to the upper limit of the silent drying temperature.

[0018] Furthermore, in step S2, the fan speed V 静音 Can be adjusted continuously and infinitely, or the fan speed V 静音 The gear speed can be adjusted according to the fixed frequency fan gear setting.

[0019] Furthermore, in step S2, the heating device power W 静音It can be continuously and steplessly adjusted, or the power W of the heating device 静音 It is adjusted in steps according to the power of one or at least two selected heating tubes, or the power W of the heating device 静音 The power W of the heating device is adjusted according to the on-off frequency of the heating tubes 静音 Adjusted in steps.

[0020] Further, in step S2, the fan speed V 静音 and the power W of the heating device 静音 can be arbitrarily combined.

[0021] Further, the silent drying control method uses any one of the methods of stopping when the clothes are dry, triggering the stop judgment, the longest drying time limit judgment condition, and the cold state NTC minute average temperature limit judgment condition to stop; or the silent drying control method uses any two of the methods of stopping when the clothes are dry, triggering the stop judgment, the longest drying time limit judgment condition, and the cold state NTC minute average temperature limit judgment condition to stop according to the competition principle, and triggers the silent drying stop judgment when any one of the competition principles is met; or the silent drying control method uses any three of the methods of stopping when the clothes are dry, triggering the stop judgment, the longest drying time limit judgment condition, and the cold state NTC minute average temperature limit judgment condition to stop according to the competition principle, and triggers the silent drying stop judgment when any one of the competition principles is met.

[0022] Compared with the prior art, the silent drying control method of the present invention has the following advantages:

[0023] (1) The silent drying control method of the present invention significantly reduces the operating noise of the equipment while ensuring the drying effect by optimizing the fan speed and the power of the heating device. Users can use the equipment with confidence at night or in occasions where a quiet environment is required without worrying about noise interference. This design is especially suitable for families with babies, the elderly, or those sensitive to noise, improving the overall user experience.

[0024] (2) The silent drying control method of the present invention has the ability of multi-step adjustment and stepless adjustment. Users can flexibly select the appropriate wind speed and heating power according to actual needs. This flexibility enables the equipment to adapt to different drying requirements, further enhancing its practicality and market competitiveness.

[0025] (3) The silent drying control method of the present invention ensures the efficiency and safety of the drying process, reduces energy waste, and improves the intelligence level of the equipment by introducing intelligent stop judgment conditions including stopping when the clothes are dry, the longest drying time limit judgment condition, and the cold state NTC minute average temperature limit judgment condition, making it more worry-free and convenient for users during use.

[0026] Another object of the present invention is to provide a laundry treatment device that adopts the silent drying control method as described above.

[0027] Further, a drying program and a silent drying program are set on the laundry treatment device. The drying program and the silent drying program are relatively independent drying programs. Alternatively, a drying program and silence are set on the laundry treatment device. After the user selects the drying program, the user can enter the silent drying program by selecting the silent option.

[0028] Further, the laundry treatment device includes two fan speeds, namely the normal drying speed V 正常 and the speed V of silent drying 静音 , and the laundry treatment device is set to include at least two heating tubes with different specifications, namely heating tube one and heating tube two. The working heating power of heating tube one is less than that of heating tube two. The heating device power of the laundry treatment device includes three combinations, namely heating tube one works, heating tube two works, and heating tube one and heating tube two are fully open. Alternatively, the laundry treatment device is set to include at least one heating tube, and the gear power of the heating tube is adjusted according to the on-off frequency of the heating tube.

[0029] Further, the laundry treatment device selects the silent drying mode and the operating parameters in the silent drying mode through the function selection buttons, remote app or remote control set on the device.

[0030] The laundry treatment device has the same advantages as the above-mentioned silent drying control method compared with the prior art, and will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 is a schematic structural diagram of the heat exchanger according to the embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] In order to make the technical means, objectives and effects of the present invention easy to understand, the embodiments of the present invention will be described in detail below with reference to specific drawings.

[0034] It should be noted that all terms indicating direction and position in the present invention, such as "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "inner", "outer", "top", "bottom", "lateral", "longitudinal", "center", etc., are only used to explain the relative positional relationship and connection conditions between components in a specific state (as shown in the attached drawings), and are only for the convenience of describing the present invention, rather than requiring the present invention to be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly specified and defined, the terms "mounted", "connected", and "coupled" shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0036] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0037] The present invention discloses a silent drying control method, which includes the following steps:

[0038] S1: Determine whether to enter the silent drying program. If so, execute S2; if not, execute S3;

[0039] S2: Adjust the fan speed V of the laundry treatment device 静音 and the power W of the heating device 静音 ;

[0040] S3: Execute the fan speed V under normal drying conditions 正常 and the power W of the heating device 正常 ;

[0041] wherein, V 静音 <V 正常 , W 静音 <W 正常 .

[0042] The present application discloses a silent drying control method. When the silent drying function is executed at night, the core lies in dynamically adjusting the working parameters of the clothing processing device according to the mode selection of whether to enter the silent drying program. Specifically, when it is necessary to execute the drying program and the user selects or the system automatically determines to enter the silent drying mode, this method will automatically reduce the fan speed to V 静音 level and adjust the power of the heating device to W 静音 state. These two silent parameters are both lower than V 正常 and W 正常 under normal drying conditions. The clothing processing device starts to execute the corresponding silent drying program and ends after the drying stop determination; when it is determined that there is no need to enter the silent drying mode, the clothing processing device executes the normal drying program, and adjusts the fan speed and the power of the heating device of the clothing processing device to the fan speed V 正常 and the power of the heating device W 正常 respectively, and ends after the drying stop determination. This adjustment mechanism sacrifices part of the drying speed and efficiency in exchange for a low-noise environment during equipment operation, and is particularly suitable for occasions at night or where a quiet environment is required. The system, through the built-in control logic, real-time monitors the selection of the drying mode and switches to the corresponding parameter settings accordingly, ensuring that the fan and the heating device operate at lower power and speed in the silent mode, thereby effectively reducing the noise generated during the mechanical rotation and heat energy conversion processes and achieving the purpose of silent drying.

[0043] Adopting the silent drying control method of the present invention, the clothing processing device can significantly reduce the noise level during operation at specific times or according to user needs, providing a more peaceful living environment for users. This intelligent control strategy not only improves the user experience, especially at night or during rest periods, avoiding the noise interference that may be brought by traditional drying methods and ensuring the user's sleep quality and living quality. Although the drying speed and efficiency are reduced in the silent mode, this design takes into account the diversity of user needs, gives users more choices, and meets the usage requirements in different scenarios. In addition, reducing the fan speed and heating power helps to reduce energy consumption, conforms to the current environmental protection trend of energy conservation and emission reduction, and in the long run, is also beneficial to reducing the user's usage cost. Valley electricity prices can be used during late-night periods to reduce the drying cost, reflecting the innovative concept of combining technological innovation and environmental protection concepts.

[0044] As a preferred example of the present application, in step S2, the fan speed V 静音 includes at least two gears, namely V 静音1 and V 静音2 , where V 静音1 <V 静音2 ; the power of the heating device W静音 It includes at least two gears, namely W 静音1 and W 静音2 , where W 静音1 < W 静音2 . As a preferred example of this application, the fan speed V 静音 includes three gears, namely V 静音1 , V 静音2 , and V 静音3 , where V 静音1 < V 静音2 < V 静音3 ; The power W of the heating device 静音 includes three gears, namely W 静音1 , W 静音2 , and W 静音3 , W 静音1 < W 静音2 < W 静音3 . Based on the silent drying control method, the present invention further refines the adjustment gears of the fan speed and the power of the heating device. This design allows the system to automatically select the most suitable fan speed gear and heating power gear according to the drying time set by the user or the preset silent level, so as to more precisely control the noise level on the premise of ensuring the drying effect and meet the personalized needs of different users for the silent degree.

[0045] By introducing multi-gear settings for the fan speed and the power of the heating device, the present invention significantly improves the flexibility of silent drying control and the customization degree of the user experience. Users can flexibly select a suitable silent gear according to their own needs, such as the urgency of the drying time or the sensitivity to noise. In this way, not only the smooth completion of the drying task is ensured, but also the noise interference is minimized. In addition, for different clothing materials and drying amounts, users can select a lower silent gear, thereby further reducing energy consumption and achieving energy conservation and environmental protection. Such a design reflects the humanization of technology, makes the clothing treatment equipment more in line with the actual needs of users in terms of silent drying, and ultimately improves the market competitiveness of the product. By meeting the personalized silent needs of users, this intelligent adjustment mechanism not only improves the use comfort of the equipment, but also increases the user's brand stickiness, promoting the further development of the market.

[0046] As a preferred example of this application, the clothing treatment equipment with the silent drying control method includes two fan speeds, namely the normal drying speed V 正常 and the speed V of silent drying 静音, and the laundry treatment device is set to include at least two heating tubes with different specifications, namely heating tube 1 (about 200W) and heating tube 2 (about 350W). Therefore, the heating device power of the laundry treatment device has three combinations, that is, heating tube 1 works, heating tube 2 works, and both heating tube 1 and heating tube 2 are fully open. In the normal drying or normal drying working state, due to the large air volume, both heating tubes can be fully open; while in the silent drying program, only one heating tube is selected to be turned on. Specifically, which heating tube to turn on needs to be selected according to the fan speed of the silent drying and the upper temperature limit allowed by the silent drying. Preferably, in the silent drying program, it is preferred to turn on heating tube 1 with 200W to avoid turning on heating tube 2 with a relatively large power, resulting in too high a temperature inside the drum.

[0047] As a preferred example of the present application, in step S2, the fan speed V 静音 can be continuously adjusted steplessly, or the fan speed V 静音 can be adjusted according to the set frequency of the fixed-frequency fan; the heating device power W 静音 can be continuously adjusted steplessly, or the heating device power W 静音 is adjusted in steps according to the power of one or at least two selected heating tubes; or the heating device power W 静音 is adjusted in steps for the heating device power W according to the on-off frequency of the heating tubes 静音 This application can achieve the continuous stepless adjustment function of the fan speed V 静音 and the heating device power W 静音 by adopting an advanced control system; it can also use a fixed-frequency fan to adjust the fan speed according to different wind speed gears. Specifically, the system relies on a high-precision sensor feedback system. These sensors can real-time monitor the current states of the fan speed and heating power, and feed these data back to the central processing unit. The central processing unit quickly analyzes and processes the collected data according to the preset silent mode algorithm, and then issues precise adjustment instructions to the drive modules of the fan and the heating device. The drive modules then adjust the fan speed and heating power in a smooth and continuous manner according to these instructions, ensuring that during the entire adjustment process, the device operates in a low-noise state, while meeting the user's fine requirements for wind speed and temperature control. This adjustment process constitutes a closed-loop control system, which can perform adaptive adjustment according to environmental changes and user preferences to ensure the best balance between the silent effect and the comfortable experience. In some examples of the present application, the heating device power W 静音 is adjusted in steps for the heating device power W according to the on-off frequency of the heating tubes 静音During step-less adjustment, for example, when the rated power of the heating tube is 100w, at this time, when performing silent drying, a heating power of 60w is required. The heating tube is controlled to execute according to a heating frequency of turning on for 3s and turning off for 2s, and the gear adjustment of 60w heating power can be achieved. Under this working condition, the rated power of the heating tube can be any one of the heating tubes with a power between 100w and 2000w. Preferably, a commercially available common heating tube can be selected, or a heating tube assembly can be formed according to multiple heating tubes, and then the power W of the heating device can be adjusted according to the on-off frequency of the heating tube assembly. 静音 Step-less adjustment.

[0048] Through continuous stepless adjustment, this application enables the device to accurately match user needs within a wider range. Whether it is the night mode that pursues extreme quietness or the instant heating requirement that needs rapid temperature rise, both can be perfectly satisfied. This flexibility greatly enhances the applicability of the device. Users can freely adjust according to the actual situation, avoiding the abruptness and discomfort brought by traditional step adjustment, making the wind speed change and temperature adjustment more natural and smooth, and improving the overall comfort of use.

[0049] As a preferred example of this application, in step S2, the fan speed V 静音 and the power W of the heating device 静音 can be arbitrarily combined. In a preferred example of this application, the fan speed V 静音 and the power W of the heating device 静音 in the silent drying mode can achieve arbitrary combination adjustment, enabling the system to effectively receive user instructions or adjust according to a preset algorithm, independently and flexibly adjusting the fan speed and the power output of the heating device. Specifically, users can freely select a suitable combination of speed and power within the set range of V 静音 and W 静音 according to actual needs. During the operation of the system, it can continuously monitor changes in the drying environment, including factors such as clothing type, humidity, and ambient temperature, and dynamically optimize and adjust the fan speed and heating power based on this information to ensure the best drying effect at the lowest noise level. This adjustment method of free combination not only improves the flexibility of the device but also enhances the user's operation experience.

[0050] This setting enables the fan speed V 静音 and the power W of the heating device 静音The arbitrary combination adjustment significantly improves the flexibility and intelligence level of the clothing treatment device. Users can customize and select the most suitable drying parameters according to various factors such as personal preferences, clothing materials, and drying urgency. In this way, not only the drying efficiency is ensured, but also the noise interference is minimized. In addition, this combination adjustment ability enables the device to accurately adapt to the needs of different drying stages. For example, at the initial stage of drying, higher wind speed and power are adopted to quickly remove the moisture on the surface of the clothes, while at the later stage of drying, the rotation speed and power are reduced to complete the drying in a more gentle way, protecting the clothes from damage. This refined control not only improves the drying quality, but also further saves energy and extends the service life of the device, providing users with a more considerate, efficient, and environmentally friendly drying experience.

[0051] As a preferred example of this application, when executing the silent drying program, the rotation speed of the inner barrel is adjusted to the inner barrel rotation speed Q 静音 , and the rotation speed of the inner barrel is Q under normal drying conditions 正常 , Q 静音 <Q 正常 . Specifically, when the device enters the silent drying mode, the system will automatically identify the current working mode and adjust the rotation speed of the inner barrel to Q 静音 according to the preset parameters. This rotation speed setting is designed to reduce the friction and collision between the clothes and the inner barrel wall, thereby effectively reducing the noise generated during the silent drying process. The intelligent control mechanism of the system can real-time monitor the operating state of the inner barrel and make precise adjustments according to the set silent mode to ensure that users can enjoy a quiet environment during use while keeping the drying effect of the clothes unaffected. In addition, the structure of the inner barrel can be drum type or agitator type. The flexibility of this design makes this technology applicable to various types of clothing treatment devices, ensuring a wide range of application scenarios.

[0052] By reducing the rotation speed of the inner barrel under the silent drying program in this application, the noise generated during the operation of the device is effectively controlled, creating a more quiet and comfortable living environment for users. This silent effect is especially suitable for use at night or in a quiet environment, avoiding the problem of excessive noise in the traditional drying mode. In addition, reducing the rotation speed of the inner barrel in this application does not sacrifice the drying efficiency. Instead, through a refined control strategy, a perfect balance between silence and efficiency is achieved, not only improving the market competitiveness of the product, but also further meeting the pursuit of high-quality life by users, enabling users to enjoy a more quiet use experience while enjoying efficient drying.

[0053] As a preferred example of the present application, when the silent drying program is executed, the drying duration in the drying program is T1; under normal drying conditions, the drying duration in the drying program is T2, and T1 > T2. This setting optimizes the drying duration. By extending the running duration under the silent drying condition, it ensures that the clothes can be fully dried while reducing the noise. Considering that in the silent drying mode, due to the reduction of the inner barrel rotation speed or the implementation of other silent measures, the drying efficiency may decrease. Therefore, by appropriately increasing the drying duration, this potential efficiency loss can be effectively compensated, ensuring that the drying performance is not affected. When the system executes the silent drying program, it can intelligently identify the current mode and automatically adjust the drying duration to ensure that the clothes can be fully dried in a longer time in the silent mode. Such a design not only meets the user's requirement for a quiet usage environment but also ensures the drying effect of the clothes, finding an ideal balance between silent drying and efficiency for the device.

[0054] By extending the drying duration under the silent drying condition, the present application not only successfully solves the contradiction between silence and drying efficiency but also further improves the user experience. This design demonstrates the product's profound understanding of user needs, that is, while pursuing low noise, it does not forget to ensure the basic drying performance, enabling users to enjoy the silent drying while also obtaining a satisfactory drying effect, bringing a more considerate and efficient user experience and enhancing the user's recognition and satisfaction with the product.

[0055] As a preferred example of the present application, the silent drying control method uses any one of the following methods to determine the stop: the trigger to stop when the clothes are dry, the longest drying time limit to determine the stop condition, and the cold state NTC minute average temperature limit to determine the stop condition; or the silent drying control method uses any two of the competition principles of the trigger to stop when the clothes are dry, the longest drying time limit to determine the stop condition, and the cold state NTC minute average temperature limit to determine the stop condition, and triggers the silent drying stop when any one of the competition principles is met; or the silent drying control method uses all three competition principles of the trigger to stop when the clothes are dry, the longest drying time limit to determine the stop condition, and the cold state NTC minute average temperature limit to determine the stop condition, and triggers the silent drying stop when any one of the competition principles is met. The silent drying control method of the present application automatically triggers the function of stopping when the clothes are dry based on the real-time monitoring of the clothes humidity by the sensor, avoiding over-drying. The specific stop logic is as follows:

[0056] Judgment Stop 1: Based on sensor data, including data detected by water temperature sensors, cold state sensors, and hot state sensors, judgment stop calculations are performed. When the heating tube in the laundry treatment device is turned on during the silent drying program, pre-judgment stop detection is carried out. When the pre-judgment stop conditions are met, combined with the preset heating time for the pre-judgment stop conditions, for example, pre-judgment stop detection is carried out according to the water level. When the pre-judgment stop conditions are met, heating is stopped after executing the preset heating time (such as 60 minutes for water level L1, 70 minutes for water level L2, and 80 minutes for water level L3); it can also be pre-judgment stop detection and judgment based on the type of clothes, pre-judgment stop detection and judgment based on the weight of the clothes, pre-judgment stop detection and judgment based on the energy consumption in the drying stage, pre-judgment stop detection and judgment based on historical drying data, pre-judgment stop detection and judgment based on humidity or moisture content, pre-judgment stop detection and judgment based on user preferences (such as dry, moderate, wet). When the pre-judgment stop conditions are met, combined with the preset heating time that meets the pre-judgment stop conditions, the heating device continues to heat for the preset heating duration and then stops heating.

[0057] Judgment Stop 2: Set the longest drying time limit. When this time is reached and the condition of clothes being dry and stopped is not met, the machine will automatically stop to prevent over-drying.

[0058] Judgment Stop 3: Stop when the average temperature limit of the cold state NTC for minutes is reached. When the temperature reaches 70°C and other judgment stop conditions are met, the cooling stage is triggered, and a 3-minute cooling time is reserved to protect the clothes from high-temperature damage.

[0059] During use, the laundry treatment device can perform judgment stop for the silent drying program according to any one of the above judgment stop principles; it can also combine any two judgment stop principles, such as combining Judgment Stop 1 and Judgment Stop 2, combining Judgment Stop 2 and Judgment Stop 3, or combining Judgment Stop 1 and Judgment Stop 3. Drying judgment stop is carried out according to the principle that drying stops when the two judgment stop conditions are met first; it can also be the combination of Judgment Stop 1, Judgment Stop 2, and Judgment Stop 3. Drying judgment stop is carried out according to the principle that drying stops when the above three judgment stop conditions are met first. As a relatively simple usage method, Judgment Stop 2 can be selected, that is, judgment stop according to the set longest drying time limit condition. Since the silent drying program is mostly executed during sleeping at night and the program execution time is extended, on the basis of ensuring the silent effect, the safety and drying effect of the clothes are further guaranteed.

[0060] When the clothing treatment device of the present application executes the silent drying control program, the device will detect the water level gear inside the inner tub, and set the corresponding drainage time and dehydration time based on the water level gear to ensure the effective removal of residual washing water, and further remove the water in the clothes by high-speed rotation. At different water level gears, the additional drying time and the maximum drying time limit for stopping judgment of the clothes will gradually increase with the increase of the water level, ensuring the intelligence and flexibility of the drying process. Specifically, in the example of the present application, when executing the silent drying control program, detecting the gear of the water level inside the inner tub may include the L1 water level, the L2 water level, and the L3 water level, and then setting the drainage time and dehydration time based on the water level gear. For example, the drainage time is set to 20s to 200s, preferably 60s, to effectively remove residual washing water; the dehydration time is set to 1min to 10min, preferably 5min, to further remove the water in the clothes by high-speed rotation; at different water level gears, the additional drying time of the clothes gradually increases with the increase of the water level gear. For example, the additional drying times corresponding to the L1 water level, the L2 water level, and the L3 water level gears are 60min, 70min, and 80min respectively. Under different water level conditions, the maximum drying time limit for stopping judgment also gradually increases with the increase of the water level gear. For example, the maximum drying time limits for stopping judgment corresponding to the L1 water level, the L2 water level, and the L3 water level gears are 130min, 190min, and 240min respectively, and entering the cooling stage is triggered. In the example of the present application, the setting of the water level gear is mainly common in pulsator washing machines. Generally, drum washing machines are set to stop heating after a pre-judgment stop condition + a fixed preset heating duration. In the example of the present application, the cold-state NTC average temperature limit judgment condition for minutes can be preferably set to 70°C, and entering the cooling stage is triggered. As a preference, in the example of the present application, the reserved cooling time is 2 to 5min, preferably 3min.

[0061] Through the setting of multiple stopping judgment conditions, the present application ensures both the drying effect and the protection of clothes. Users do not need to worry about the clothes being damaged due to over-drying during the use process. This design greatly improves the user experience. Users can safely put the clothes into the device, and the system will automatically judge and adjust the drying process, avoiding the common problems of insufficient drying or over-drying in the traditional drying mode. This silent drying control method not only improves the drying efficiency, but also creates a more convenient and comfortable user experience for users, further enhancing the market competitiveness of the product, making it stand out among many clothing treatment devices, and meeting the pursuit of high-quality life by users.

[0062] In the examples of this application, the adjustment of the fan speed is the core technology for achieving silent drying control. To effectively adjust the fan speed, a variable-frequency fan is required as the hardware basis; in some examples, a fixed-frequency fan can also be used in a downshift mode to adjust the fan speed according to different wind speed gears. Generally speaking, the lower the fan speed, the lower the generated noise and wind noise. However, a lower wind speed will lead to a slowdown in the drying speed. Therefore, when selecting the fan wind speed, within the noise range acceptable to the user (determined jointly through noise chamber technology testing and internal testing by product consumers), a higher wind speed should be selected as much as possible to balance noise and drying efficiency.

[0063] After determining the fan wind speed, the next step is to select an appropriate heating power to ensure that the temperature of the device is controlled within a predetermined range. This temperature range should be the smaller value of the long-term tolerance of the device and the tolerance of the user's clothes. In addition, the selection of the rotation speed and rotation-stop ratio of the inner drum is determined through experiments. The experiments involve different combinations of rotation speeds and rotation-stop ratios to measure their effects on the drying speed and uniformity, so as to optimize the operating parameters of the inner drum to achieve the best drying effect.

[0064] This application also discloses a laundry treatment device that adopts the above-mentioned silent drying control method. When the user uses the above-mentioned silent drying control method to dry clothes, the silent drying mode needs to be selected. As a preferred example of this application, a drying program and a silent drying program are set on the laundry treatment device. The drying program and the silent drying program are relatively independent drying programs. Alternatively, a drying program and silence are set on the laundry treatment device, and the user enters the silent drying program by selecting the silent option after selecting the drying program. The laundry treatment device disclosed in this application integrates the silent drying control method. When the drying program and the silent drying program are relatively independent drying programs, the core working principle is that the device has two sets of independent drying programs built-in, namely a standard drying program and a specially designed silent drying program. The user can choose the corresponding drying mode according to their own needs when using it. If the user hopes to perform the drying operation in a quiet environment, the silent drying mode can be selected, and this selection can be achieved through a special option on the device interface; when it is set that the user enters the silent drying program by selecting the silent option after selecting the drying program, after the user first selects the basic drying program, and then checks or clicks the "silent" option, the device will automatically switch to the silent drying program. In this mode, the device will optimize various parameters during the drying process, including adjusting the wind speed, temperature, and operation mode, etc., to significantly reduce the noise level while ensuring that the drying efficiency and quality are not affected.

[0065] This setting introduces a silent drying mode on the laundry treatment device, enabling the device to maintain a low working noise while drying clothes. This is particularly important for families or specific usage scenarios that require a quiet environment. Users don't have to worry about noise disturbing their sleep when using the device at night, meeting the usage needs of users in different scenarios, enabling the device to flexibly handle various environments, and providing a more user-friendly service.

[0066] As a preferred example of this application, the laundry treatment device selects the silent drying mode and the operating parameters in the silent drying mode through the function selection buttons, remote app, or remote control set on the device.

[0067] By setting function selection buttons, remote APPs, or remote controls, users can flexibly select the silent drying mode and its operating parameters. Users can monitor and adjust the drying process at any time whether at home or away. This convenience makes laundry treatment more efficient, reduces the waiting time of users, and greatly improves the convenience of the device and the user experience.

[0068] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
