[0021] The embodiments of the present application are described below in conjunction with the drawings in the present application. It should be understood that the implementation methods described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0023] The present application provides a control method, system and clothes drying machine for adjusting wind speed, such as Figure 1 A control method for wind speed regulation provided in an embodiment of the present invention is applied to a clothes drying machine, comprising: obtaining a current air outlet speed of an air outlet module of the clothes drying machine; calculating an operating power of the air outlet module through an air outlet model according to the current air outlet speed and a target air outlet speed of the air outlet module, so as to adjust the operating power of the air outlet module and adjust the current air outlet speed of the air outlet module to the target air outlet speed.

[0024] The wind speed regulation model includes: P = K P ×(AB)+K i ×∫e(t)dt, where e(t)=(AB); where P is the operating power value, K P is the proportional gain, A is the target wind speed, B is the current wind speed, K i is the integral gain; the operating power value of the air outlet module is adjusted according to the wind speed regulation model.

[0025] Proportional control is a control method that generates control output based on the size of the difference. The basic principle is: the larger the difference, the greater the control output. Among them, (AB) represents the difference. The proportional gain Kp reflects the sensitivity of the control output to the difference. A larger Kp makes the system more sensitive and responds faster, but may cause system instability; a smaller Kp makes the system more stable, but may cause the system to respond slower.

[0026] Combined, the proportional gain of this application is 0.5 to 1.5, that is, K P =0.5~1.5; when K P =0.8, the target air outlet speed is 3.3m / s, the current air outlet speed is 1.2m / s, the difference is 2.1m / s, and the proportional control output is 1.68 (i.e. 0.8×2.1). This control output is used to adjust the power of the air outlet module to speed up the speed to the target air outlet speed.

[0027] Integral control is a control method that generates control output based on the accumulated value of the difference. The basic principle is: the greater the accumulated difference, the greater the control output. Continuing with the wind speed control example above, the integral gain of this application is 0.2~0.5, that is, K i = 0.2~0.5, if there is a continuous difference in the system, the integral control will continue to accumulate these differences and generate corresponding control outputs to eliminate these differences. Assume that the integral gain K i With a setting of 0.4, the control output will be used to continuously adjust the power to the heating device to eliminate the continuous difference and reach a steady state.

[0028] By combining these two control methods, a balance between system stability and response speed can be achieved.

[0029] The wind speed regulation model also includes a differential control term. The wind speed regulation model is adjusted to P = K P ×(AB)+K i ×∫e(t)dt+K d ×(de / dt), where e(t) = (AB); where P is the operating power value, K P is the proportional gain, A is the target wind speed, B is the current wind speed, K i is the integral gain, K d is the differential gain, de / dt is the rate of change of the difference over time;

[0030] By dynamically adjusting the proportional gain, integral gain and differential gain through the difference between the target outlet wind speed and the real-time monitoring of the current outlet wind speed, the operating power value can be precisely controlled.

[0031] Therefore, the wind speed regulation control method provided by the present application realizes precise control of the air outlet process by combining proportional control, integral control and differential control. This control method not only improves the user experience of air outlet, but also effectively prolongs the service life of the air outlet module, reduces energy consumption, and has significant practical value and economic benefits.

[0032] The calculation formula of the differential control term is: D = K d ×(de / dt); where K d =0.1~0.5; where D is the differential control term, which is used to predict the future trend of the difference change of the system, K d is the differential gain, which is the response degree to the rate of change of the difference, and de / dt is the rate of change of the difference over time, where the difference is the target outlet wind speed and the current outlet wind speed, that is, (AB).

[0033] The differential control term is used to improve the stability and predictability of the air flow process. In actual applications, wind speed fluctuations may occur during the air flow process due to the influence of factors such as air pressure, temperature, and humidity. The differential control term can predict and adjust the output of the air flow module in a timely manner by responding to the rate of change of the difference, thereby reducing temperature fluctuations and ensuring a smooth air flow process. When the rate of change of the difference over time is large, the differential control term will increase the control output to quickly respond to temperature changes, and vice versa, it will reduce the control output to avoid system oscillations caused by over-adjustment.

[0034] In the embodiment of the present application, the differential gain K d The value range of is 0.1~0.5, which is obtained through experiments and optimization, aiming to ensure that the differential control term can effectively predict the temperature change trend without causing excessive oscillation to the system. d When the value is 0.3, if the difference change rate de / dt is large, it means that the wind speed changes quickly. At this time, the differential control term D will increase accordingly, thereby increasing the control output and quickly adjusting the power of the air outlet module to stabilize the air outlet process. On the contrary, if the difference change rate is small, the differential control term D will decrease, reducing the adjustment of the air outlet module power and avoiding unnecessary system oscillations.

[0035] Dynamically adjust the proportional gain, integral gain and differential gain, which is the compensation mechanism. The compensation mechanism is implemented by automatically adjusting the proportional gain K when the wind speed changes beyond the preset threshold. P , integral gain K i and differential gain K d The specific adjustment formula is: KP'=KP×(1+α×ΔF), Ki'=Ki×(1+β×ΔF), Kd'=Kd×(1+γ×ΔF), where KP', Ki', Kd' are the adjusted proportional gain, integral gain and differential gain respectively, α, β, γ are compensation coefficients, and ΔF is the wind speed change value.

[0036] In practical applications, the determination of the three compensation coefficients α, β, and γ requires precise calculation based on the characteristics of the air outlet module and the dynamic response of the air outlet process. Usually, the selection of these coefficients will be optimized through experimental data to ensure that the control system can quickly and accurately adjust the operating power in different environments to achieve the ideal air outlet effect. In addition, in order to further improve the adaptability and robustness of the control system, intelligent control algorithms such as fuzzy logic or neural networks can be introduced to dynamically adjust the compensation coefficients to cope with more complex and changeable environments.

[0037] The present application also provides a wind speed regulation and control system, comprising a main control unit, a wind speed detection unit and a wind speed module driving unit; the wind speed detection unit is connected to the main control unit, and is used to detect the current air outlet information of the clothes drying machine heating module, and transmit the detected current air outlet wind speed information to the main control unit; the main control unit is connected to the wind speed module driving unit, and is used to execute the wind speed control method of the above-mentioned clothes drying machine, and generate a wind speed regulation driving signal according to the operating power calculated by the wind speed regulation model; the wind speed module driving unit is connected to the clothes drying machine air outlet module, and is used to adjust the operating power of the air outlet module according to the wind speed driving signal sent by the main control unit, so that the current air outlet wind speed of the air outlet module is adjusted to the target air outlet wind speed.

[0038] In practical applications, in order to ensure the stability and response speed of the control system, a proportional-integral (PI) control algorithm is used in the embodiments of the present application. This algorithm combines the advantages of proportional control and integral control, and can effectively reduce system overshoot, shorten the adjustment time, and improve control accuracy. Specifically, the proportional control part can quickly respond to changes in wind speed difference, while the integral control part can eliminate the steady-state difference and ensure the accuracy of long-term operation of the system.

[0039] In the embodiment of the present application, the selection of proportional gain and integral gain is based on in-depth analysis and experimental verification of the dynamic characteristics of the system. By adjusting these two parameters, the response speed and stability of the system can be flexibly controlled. For example, when the proportional gain is set to 0.8, the system responds to the wind speed difference more quickly, and when the integral gain is set to 0.4, the system can effectively eliminate the cumulative difference caused by the continuous existence of the wind speed difference.

[0040] The user controls the target wind speed through the remote control, mobile app, or voice control. The main control unit receives the signal and the clothes drying machine starts the wind function. At this time, the main control unit obtains the current wind speed of the air outlet through the wind speed detection module through the communication circuit, and then puts the current wind speed and the target wind speed into the wind speed adjustment mode to obtain the next fan power value. The main control unit sets the fan power value through the wind speed module driver unit.

[0041] The wind speed detection unit includes a wind speed sensor, which is arranged at the air outlet of the clothes drying machine; the wind speed sensor includes but is not limited to a wind speed tube, an ultrasonic wind speed probe, and a thermal mass flow meter probe.

[0042] The wind speed sensor is responsible for real-time monitoring of the wind speed at the air outlet and converting the detected data into electrical signals. These signals are then sent to the main control unit for processing. In the main control unit, the signal is amplified and filtered to ensure the accuracy and stability of the data. The main control unit then analyzes the signal based on the built-in control algorithm to determine whether the power output of the fan needs to be adjusted. If there is a deviation between the detected wind speed and the preset target wind speed, the main control unit will calculate the corresponding adjustment amount and adjust the fan speed through the wind speed module drive unit to achieve precise control of the wind speed. The whole process is dynamic, ensuring that the clothes drying machine can provide appropriate wind speed under different working conditions to achieve the best clothes drying effect.

[0043] When the wind speed sensor is a thermal mass meter probe, the thermal mass flow meter probe detects the wind speed by measuring the heat transfer effect of the fluid and transmits it to the main control unit, thereby controlling the wind speed module drive unit to achieve precise control of the air outlet process.

[0044] Thermal mass flow meter probes have high sensitivity and accuracy and can detect small changes in wind speed, which is particularly important for situations where precise wind speed control is required. For example, during the air flow process, changes in clothing humidity will affect the suitability of the wind speed. Thermal mass flow meter probes can monitor and feedback these changes in real time, allowing the control system to adjust the power output of the air outlet fan in time to adapt to changes in clothing humidity, thereby improving air drying efficiency and quality.

[0045] The air outlet module is a brushless motor; the wind speed module drive unit adopts a three-phase H-bridge drive circuit, combined with the vector control drive or square wave drive algorithm of the main control unit to achieve precise control of the brushless motor speed.

[0046] The wind speed module drive unit includes a drive chip and a power amplifier module. The drive chip controls the output of the power amplifier module according to the instructions of the main control unit, thereby adjusting the power of the air outlet module. The power amplifier module usually uses power semiconductor devices such as MOSFET or IGBT to achieve fast and precise control of current. In addition, in order to protect the air outlet module and circuit from damage, the wind speed module drive unit is also designed with a current detection and overcurrent protection mechanism. When it is detected that the current exceeds the safety threshold, the power supply will be automatically cut off to prevent damage to the equipment due to overload.

[0047] In the embodiment of the present application, the wind speed detection unit also has a self-calibration function, which can regularly calibrate the accuracy of the wind speed sensor to ensure the accuracy of wind speed detection in long-term operation. The self-calibration function regularly compares the output of the wind speed sensor with the built-in reference signal source, automatically adjusts the output value of the sensor to compensate for errors caused by environmental changes or sensor aging, and ensures the reliability and durability of the device.

[0048] The main control unit monitors the wind speed in real time through the wind speed detection unit, and dynamically adjusts the power output of the air outlet module according to the detected wind speed value. This real-time monitoring and dynamic adjustment mechanism ensures more accurate wind speed control during the air outlet process, while reducing the problem of unstable air outlet effect caused by environmental wind speed fluctuations.

[0049] The main control unit also has a fault diagnosis function, which can promptly detect and handle abnormal situations in the wind speed process, such as wind speed sensor failure, air outlet module non-operating, etc., thereby ensuring the continuity and safety of the air outlet process.

[0050] The wind speed regulation control system also includes a safety protection module. When it is detected that the working state of the air outlet module is abnormal, the power supply of the air outlet module is cut off through the wind speed module driving unit and an early warning is provided; the abnormal state includes but is not limited to abnormal temperature.

[0051] In practical applications, the air outlet control system of the present application can also have the function of intelligently identifying clothing. For example, for lighter or thinner clothing, the system will automatically reduce the air outlet time, and for heavier or thicker clothing, the air outlet time will be appropriately extended to ensure that the clothing is air-dried evenly and without damage. In addition, the system can also monitor the wind speed, humidity and temperature of the environment in real time through built-in sensors, and automatically adjust the power output of the air outlet module to maintain a constant wind, temperature and humidity state during the air outlet process, thereby improving the air drying efficiency and the air drying quality of clothing.

[0052] In order to further optimize the air-drying effect, a heating device can also be introduced. The system automatically adjusts the heating efficiency of the heating device according to the drying progress of the clothes and the humidity changes in the drying chamber, thereby ensuring that the coordination of air volume and temperature during the air discharge process reaches the best state. This technology can not only shorten the air-drying cycle, but also reduce the wrinkles and damage of clothes, and improve the quality of clothes after air-drying.

[0053] In addition, in order to further enhance the user experience, the wind speed adjustment control system of the present application may also include a user interface that allows users to set different air outlet modes according to different clothing types and air outlet requirements. For example, users can choose a fast air outlet mode to shorten the air drying time, or choose a soft air outlet mode to protect sensitive clothing from damage. The setting of the user interface enables users to operate the clothes dryer more intuitively and conveniently, and the system can automatically adjust the air outlet parameters according to the user's selection to achieve the best air outlet effect. It is also equipped with an intelligent networking function. Users can remotely control the clothes dryer through a mobile phone application, check the air outlet status in real time, and even receive notifications after the air outlet is completed. In addition, the system can automatically learn and optimize the air outlet program according to the user's usage habits and preferences to provide users with a personalized air outlet experience.

[0054] To sum up, the wind speed regulation control system of the present application provides users with efficient, safe, convenient and personalized air outlet solutions through intelligent control, fault diagnosis, safety protection, dynamic adjustment of air volume, and integration of intelligent networking and user interface.

[0055] The present application also provides a clothes drying machine, including a clothes drying machine including any of the wind speed adjustment control systems described above.

[0056] In one possible situation, the wind speed adjustment control system is arranged on the host, and the clothes drying machine includes the wind speed adjustment control system, and the wind speed adjustment control system includes a main control unit, such as Figure 2 As shown, the main control unit includes any of the above-mentioned methods for adjusting the wind speed of the clothes drying machine. The main control unit is provided with a communication circuit, which communicates with the wind speed detection module. The wind speed detection unit includes a thermal mass flowmeter probe, which is arranged at the air outlet of the clothes drying machine. The wind speed detection is achieved by measuring the different resistance values ​​of the thermal mass flowmeter probe at different temperatures. When the fluid flows, the heat of the probe will be taken away, causing the probe temperature to drop. When the fluid flows through the probe, the heat is transferred to the fluid by convection. The faster the flow rate of the fluid, the more heat is taken away, and the faster the temperature of the probe drops. By controlling the heating power and measuring the temperature change of the probe, the flow rate of the fluid can be derived. It also includes a wind speed module drive unit, which controls the air outlet module. The air outlet module is a brushless DC motor, which is arranged in the clothes drying machine. Its working principle is that the wind speed detection unit can detect the temperature change of the thermal mass flowmeter probe, derive the flow rate, that is, the wind speed, so that the main control unit obtains the air outlet wind speed. The wind speed module drive unit has a power adjustment function, which can allow the fan to work at different powers. In this way, the wind speed module drive unit can automatically adjust the power output of the fan according to the wind speed information provided by the main control unit, thereby achieving precise control of the air outlet process. When the detected wind speed is lower than the set wind speed, the wind speed module drive unit will increase the power output; conversely, when the wind speed exceeds the set value, the wind speed module drive unit will reduce the power output to prevent excessive wind speed and ensure the safety of the air outlet process. In addition, the system also has a self-diagnosis function that can monitor the working status of units and components in real time. Once an abnormality is found, the system will automatically take protective measures, such as cutting off the power supply, to avoid the expansion of the fault and ensure the safety of the user. The user interface provides an intuitive operation method. Users can set the air outlet mode and temperature according to their personal needs, and the system will automatically execute the corresponding air outlet program to achieve intelligent operation.

[0057] In another possible situation, the wind speed adjustment control system is set on the clothes drying rod, and the clothes drying rod can be raised and lowered by a steel wire rope. Therefore, when clothes and bedding are hung on the clothes drying rod, the wind blown out of the clothes drying rod can be used to air dry the clothes and bedding. If clothes and bedding are not hung on the clothes drying rod, that is, in an unloaded state, the wind blown out of the clothes drying rod can be used for a variety of purposes. First, it can be used to create indoor ventilation effects and help improve air quality, especially in a closed indoor environment. In addition, the blown wind can also be used to adjust the indoor temperature, providing a certain degree of coolness or warmth, which varies according to the season and outdoor temperature. In addition, if the clothes drying machine is set indoors, such as in a room or a balcony connected to the living room, the wind when the clothes drying rod is unloaded can also be used to dispel possible odors in the room, which can effectively improve the living environment. At the same time, it can assist in indoor temperature regulation and bring a comfortable living experience to users. In different seasons and different temperature conditions, users can obtain a suitable indoor temperature by adjusting the wind speed. Finally, this design can also add a sense of fashion to the space when the clothes drying rod is not used for drying, making it a decoration in the home. The design of the entire system takes into account both practicality and aesthetics, making the clothes drying machine an indispensable part of the home environment. At the same time, for some high-end clothes drying machine designs, the wind blown out may also have the function of dust removal or cleaning the clothes drying rod and the surrounding area to keep the clothes drying area clean.

[0058] like Figure 3 As shown, the main control unit of the clothes drying machine stores the following steps: S01, determining the target wind speed of the wind outlet module; S02, obtaining the current wind speed of the wind outlet module of the clothes drying machine; S03, calculating the operating power of the wind outlet module through the wind outlet model according to the current wind speed and the target wind speed of the wind outlet module, constructing a wind speed adjustment model, and obtaining the output parameters of the wind outlet module; calculating the difference between the target wind speed and the current wind speed, and performing proportional-integral control algorithm to adjust the operating parameters of the wind outlet module until the difference between the target wind speed and the current wind speed meets the target value; the wind speed adjustment model includes: P = K P ×(AB)+K i ×∫e(t)dt, where e(t)=(AB), where P is the operating power value, K P is the proportional gain, A is the target wind speed, B is the current wind speed, K i is the integral gain; S04, the main control unit adjusts the operating power of the air outlet module according to the wind speed regulation model; S05, continuously monitors the air outlet speed, determines the size of the current air outlet speed value and the target air outlet speed value, and then adjusts the operating power of the air outlet module to ensure that it is maintained within the target air outlet temperature range; it also includes executing the self-diagnosis function and taking corresponding protection measures if an abnormal situation occurs.

[0059] In addition to being stored in the main control unit, the above method can also be set in a storage medium. An embodiment of the present application also provides a computer-readable storage medium, in which a computer program is stored. When the computer program is loaded and executed by the processor, any of the above wind speed regulation control methods is adopted.

[0060] Among them, the computer readable storage medium can be, for example, but not limited to, an electrical, magnetic, optical, electromagnetic, infrared, or semiconductor system, device or device, or any combination of the above. More specific examples of computer readable storage media (a non-exhaustive list) include: an electrical connection with one or more wires, a portable computer disk, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM), a register, a hard disk, an optical fiber, a portable compact disk read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the above, or any other form of computer readable storage medium known in the art. An exemplary storage medium is coupled to a processor so that the processor can read information from the storage medium and write information to the storage medium. Of course, the storage medium can also be a component of the processor. The processor and the storage medium can be located in an application-specific integrated circuit (ASIC).

[0061] Although the present application has been depicted and described as a method for adjusting wind speed, it should be understood that various changes, modifications and equivalent substitutions can be made to the present application without departing from the spirit and scope of the present application. Therefore, for those skilled in the relevant art, after understanding the basic ideas and specific implementation methods of the present application, many possible changes, modifications and equivalent substitutions can be made, and these changes, modifications and equivalent substitutions should be regarded as belonging to the protection scope of the present application.
