[0002] Washing machines are indispensable tools in people's lives, bringing great convenience. With the development of technology, washing machines are becoming increasingly intelligent, offering more and more functions, and clothes drying has become a key indicator of consumer concern.

[0003] As washer-dryer products account for an increasingly larger share of home appliances, users have higher demands for drying performance. Existing washer-dryer products do not allow clothes to fully expand inside the drum when drying clothes, resulting in longer drying times, increased energy consumption, and incomplete removal of wrinkles. Users still need to stretch and shake the clothes after taking them out, leading to a poor user experience. Summary of the Invention

[0004] The purpose of this invention is to provide a method, system, washing and drying equipment, and storage medium for smoothing and wrinkle removal of clothing.

[0005] To achieve the above objectives, the following technical solution is provided:

[0006] In a first aspect, the present invention provides a method for smoothing and wrinkle-removing clothing, comprising:

[0007] Obtain the ambient humidity value of the washer-dryer equipment;

[0008] The clothes drying process is divided into the pre-drying stage and the post-drying stage, with the ambient humidity value of the washing and drying equipment as the node.

[0009] In the later stages of drying, intermittent high and low speed airflow is used to impact the clothes that are in a high position and about to fall, in order to stretch and remove wrinkles from the clothes.

[0010] As an optional solution to the garment stretching and wrinkle removal method provided by the present invention, the relative humidity at the condenser outlet is detected before the drying fan is started to obtain the ambient humidity value of the washing and drying equipment.

[0011] As an optional solution to the garment stretching and wrinkle removal method provided by the present invention, the relative humidity inside the drum is detected in real time during the garment drying process. The period from the start of garment drying to the decrease of the relative humidity inside the drum to the ambient humidity value is the pre-drying stage of garment drying, and the period from the decrease of the relative humidity inside the drum to the end of garment drying is the post-drying stage of garment drying.

[0012] As an optional solution to the garment stretching and wrinkle removal method provided by the present invention, the rotation speed and rotation-to-stop ratio of the roller are adjusted according to the relative humidity inside the roller.

[0013] As an optional solution to the garment stretching and wrinkle removal method provided by the present invention, within a preset time period before and after the alternation point of the drum's forward and reverse rotation, the rotation speed of the drying fan is reduced to a first rotation speed, and after the drum is adjusted, it rotates to a preset angle, the garment moves to a high position inside the drum, the garment is in a high position and about to fall, and the rotation speed of the drying fan is increased to a second rotation speed.

[0014] As an optional solution to the garment stretching and wrinkle removal method provided by the present invention, the weight and / or material type of the garment are determined, and a first rotational speed and a second rotational speed are determined based on the weight and / or material type of the garment.

[0017] Humidity detection module is used to obtain the ambient humidity value of the washer-dryer equipment;

[0018] The time segmentation module is used to divide the clothes drying process into a pre-drying stage and a post-drying stage, based on the ambient humidity value of the washing and drying equipment.

[0019] The airflow impact module is used in the later stage of drying clothes to intermittently impact the clothes that are in a high position and about to fall, so as to stretch and remove wrinkles.

[0020] Thirdly, the present invention also provides a washing and drying device, the washing and drying device including a memory, a processor and a computer program stored in the memory and running on the processor, wherein when the processor executes the program, it implements the garment stretching and wrinkle removal method as described above.

In the post-drying stage, intermittent high and low speed airflow impacts the clothing in a high-positioned, about-to-fall state to stretch and remove wrinkles. At low speeds, the airflow experiences a pressure drop due to the cooling effect of the evaporator, reducing the air pressure inside the drum. After speeding up, the impact force of the airflow entering the drum increases significantly, and since the clothing is in a high-positioned, about-to-fall state, the airflow impacts the clothing as it falls, removing wrinkles.

[0026] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Figure 1 The flowchart of the garment stretching and wrinkle removal method provided in this embodiment is as follows: Figure 1 As shown, this method for smoothing and wrinkle-removing clothing includes the following steps:

[0029] S101. Obtain the ambient humidity value of the washer-dryer equipment. The washer-dryer equipment can specifically be a washer-dryer set, a washer-dryer combo, or a washer-dryer integrated system. A washer-dryer set consists of a washing machine and a dryer, both operated independently and can be stacked or placed separately. Waste-dryer sets typically use heat pump drying technology and require two separate drainage and power systems. A washer-dryer combo combines washing and drying functions and is operated through a single control panel. It typically uses direct venting or condenser drying technology and offers multiple functions including washing, spinning, and drying. A washer-dryer integrated system integrates the washing machine and dryer into one unit, requiring only a control panel and a single water and electricity system. This design makes installation easier and saves space.

[0030] Ambient humidity values ​​for washer-dryers can be obtained using humidity sensors. These sensors detect changes in air humidity and convert them into measurable signals for display. There are various types of humidity sensors, commonly including capacitive humidity sensors, humidity tapers, and non-contact sensors. Capacitive humidity sensors measure humidity by assessing its effect on the saturation of a substance in the system, offering advantages such as a wide detection range and high accuracy. Humidity tapers detect humidity changes through the evaporation of molten material; while providing high accuracy, they are significantly affected by temperature. Non-contact sensors are miniature sensors capable of quickly and accurately measuring air humidity.

[0031] S102. The drying process is divided into a pre-drying stage and a post-drying stage, using the ambient humidity level of the washer-dryer as a dividing point. In the later stages of dehydration, the drum operates at high speed until it reaches a critical point of deceleration. At this point, the drying fan in the drying module starts operating at full power, triggering the heater. The airflow from the drying fan dehumidifies and preheats the clothes inside the drum. During the drying process, the relative humidity inside the drum first rises and then falls. The pre-drying stage is characterized by significant water evaporation, and the equipment operates in accordance with conventional equipment. The post-drying stage, while drying the clothes, also addresses wrinkle removal. Dividing the drying process into pre-drying and post-drying stages using ambient humidity levels allows for effective intervention and improves wrinkle removal.

[0032] S103. In the later stage of drying, intermittent high- and low-speed airflow is used to impact the clothes in a high-positioned, ready-to-fall state, in order to stretch and remove wrinkles. Intermittent high- and low-speed airflow refers to the use of intermittent pulses of high-speed and low-speed airflow to impact the clothes to varying degrees, achieving the stretching of the clothes. Specifically, intermittent high- and low-speed airflow can be achieved through multiple air ducts with different wind speeds, or by adjusting the wind speed of the same air duct. The "high-positioned, ready-to-fall state" specifically refers to the clothes being in a high position within the drum. When the drum speed is slow, the centrifugal force on the clothes is small, preventing them from adhering to the inner wall of the drum, and the clothes fall under the influence of gravity. Of course, external force can also be used to propel the clothes to a high position before they fall.

[0033] Specifically, the ambient humidity value of the washer-dryer is first obtained. Then, the drying process is divided into a pre-drying stage and a post-drying stage based on the ambient humidity value. In the post-drying stage, intermittent high and low speed airflow impacts the clothes in a high position, ready to be thrown off, to smooth and remove wrinkles. At low speeds, the airflow experiences a pressure drop due to the cooling effect of the evaporator, reducing the air pressure inside the drum. When the speed is increased, the impact force of the airflow entering the drum increases significantly. Since the clothes are in a high position, ready to be thrown off, the airflow impacts the clothes as they fall, removing wrinkles. The dried clothes are brand new, eliminating the need for users to stretch and smooth them after removing them. This meets users' higher-level clothing drying needs, enhances the wrinkle removal effect of the washer-dryer, improves the drying efficiency, shortens the drying time, enhances the user experience, reduces energy consumption, and strengthens the product competitiveness of the washer-dryer.

[0034] In some embodiments, the relative humidity at the condenser outlet is detected before the drying fan is started to obtain the ambient humidity value of the washer-dryer equipment. The ambient humidity value of the washer-dryer equipment can be obtained through a humidity sensor, which can sense changes in humidity in the air and convert them into a measurable signal for display. The relative humidity at the condenser outlet is close to the ambient humidity of the washer-dryer equipment, making it easy to detect and convenient to install a humidity sensor. The average relative humidity at the condenser outlet can be obtained at preset time intervals using a humidity sensor within that preset time period to ensure the reliability of the ambient humidity value and avoid excessive noise interference. For example, the relative humidity value at the condenser outlet measured by the humidity sensor within the previous 5 minutes is obtained every 5 minutes, and the average relative humidity within the previous 5 minutes is calculated as the ambient humidity value of the washer-dryer equipment.

[0035] Optionally, during the clothes drying process, the relative humidity inside the drum is monitored in real time. The period from the start of drying until the relative humidity inside the drum drops to the ambient humidity level is considered the pre-drying stage, and the period from the relative humidity inside the drum dropping to the ambient humidity level until the end of drying is considered the post-drying stage. During the drying process, the relative humidity inside the drum will first rise and then fall. The pre-drying stage is a period of large-scale water evaporation, and the equipment operation is consistent with conventional equipment. The post-drying stage, while drying the clothes, also takes into account wrinkle removal. Comparing the relative humidity inside the drum with the ambient humidity level as the dividing point between the pre-drying and post-drying stages allows for effective and reasonable intervention in the clothes drying process, improving the wrinkle removal effect. The division is clear, and the procedure is simple.

[0036] In some embodiments, the drum rotation speed and rotation-to-stop ratio are adjusted according to the relative humidity inside the drum. The drum rotation speed and rotation-to-stop ratio can be linked to the rotation speed of the drying fan to improve the smoothness of the clothes. By adjusting the drum rotation speed, a higher rotation speed can be used to lift and toss lightweight clothes when the clothes are less moist, maintaining the flatness of the clothes. In the early stage of drying, due to the rise in temperature inside the drum, the moisture in the clothes evaporates, and the humidity inside the drum rises rapidly until it reaches its maximum value. At this stage, a low rotation speed is sufficient to toss the clothes. As the drying process progresses, the moisture in the airflow is condensed and the rate of moisture evaporation from the clothes decreases, and the humidity inside the drum gradually decreases. At this time, a higher rotation speed is required to toss and spread the clothes. By adjusting the drum rotation-to-stop ratio, during the clothes drying process, when the moisture in the clothes is high, the drum can rotate in both directions; in the later stage of drying, when the moisture in the clothes is lower, the drum can rotate in one direction. This reduces wrinkles caused by the tumbling of the clothes during the in-between rotation. The one-way rotation ensures that the direction of the clothes being tossed is consistent with the direction of the airflow entering the inner drum, thus allowing them to be fully blown and spread out by the wind.

[0037] Optionally, within a preset time period before and after the drum's alternating forward and reverse rotation point, the drying fan speed is reduced to a first speed. After the drum reverses direction, it rotates to a preset angle, moving the clothes to a high position within the drum, where they are in a state ready to be thrown off. The drying fan speed is then increased to a second speed. This alternating forward and reverse rotation design ensures that the clothes receive comprehensive mechanical action during the drying process, resulting in better drying performance. At the drum's alternating forward and reverse rotation point, the drum rotates slowly and gradually stops, reducing the centrifugal force on the clothes and facilitating their high-positioning, ready-to-fall state. The preset time period can be 3 to 7 seconds, and the preset angle can be 110° to 130°, specifically 110°, 120°, or 130°, at which point the clothes are in a high position within the drum. In the later stages of drying, intermittent high- and low-speed airflow impacts the clothes, which are in a high position and about to fall, to stretch and remove wrinkles. The low airflow from the drying fan at the first speed reduces the air pressure inside the drum, while the high airflow from the second speed significantly increases the impact force of the airflow entering the drum. Since the clothes are in a high position and about to fall, the airflow impacts and removes wrinkles as the clothes fall. This step can be repeated multiple times to ensure the clothes are sufficiently stretched and to improve drying efficiency.

[0038] In some embodiments, the weight and / or material type of the garment are determined, and a first rotation speed and a second rotation speed are determined based on the weight and / or material type. Garment weight can be categorized according to different types of garments, such as shirts, suits, and down jackets. At the start of drying, the garment has a high moisture content and is relatively heavy; both the first and second rotation speeds can be low, with a small difference between them, using a gentle, low-speed airflow to impact and stretch the garment. As drying progresses, the moisture content of the garment gradually decreases, and the weight of the damp garment decreases; both the first and second rotation speeds can then be high, with a larger difference between them, using a high-speed, vigorous airflow to impact and stretch the garment. The garment can specifically be made of materials such as cotton, linen, synthetic fibers, silk, or wool. Different levels of the first and second rotation speeds are used for different types of garments depending on the difficulty of drying and the required drying time.

[0039] Optionally, the weight of the clothing can be determined using a gravity sensor; and / or, the material type can be determined using image recognition. The gravity sensor utilizes principles such as piezoelectric or capacitive effects to sense the tilt or vibration of the washer-dryer by measuring deformation or displacement caused by gravity. The resistance strain gauge in the gravity sensor changes with the deformation of the elastic material, thus affecting the balance of the Wheatstone bridge and generating a voltage difference. This voltage difference is proportional to the weight of the clothing, thereby achieving weight measurement. The load cell is typically installed in a suitable location within the washer-dryer, integrated with the equipment through a special structural design. When clothing is placed in the washer-dryer, the load cell detects the weight of the clothing and transmits this weight information to the washer-dryer's control system through calculation.

[0040] The washer-dryer can capture images of clothing using a camera, and then use image recognition algorithms to analyze features such as color, texture, and shape to determine the material and type of the clothing. Through camera and image recognition technology, the washer-dryer can automatically identify the clothing material and provide a personalized washing and drying solution without any additional user intervention. Furthermore, image recognition technology is more intuitive and faster than other traditional methods (such as spectral analysis and water absorption rate determination), significantly improving the user experience. Image recognition mainly includes the following steps: First, image acquisition: the washer-dryer's built-in camera captures images of the clothing; second, preprocessing: the captured image is preprocessed, such as adjusting brightness and contrast, for subsequent analysis; third, feature extraction: image recognition algorithms extract features such as color, texture, and shape from the image; fourth, material identification: the extracted features are compared with a pre-set material database to determine the type of clothing material; finally, result feedback: the recognition results are fed back to the user, and washing and drying parameters are adjusted according to the material type.

[0041] The garment stretching and wrinkle removal method provided in this embodiment first obtains the ambient humidity value of the washing and drying equipment, and then divides the garment drying process into a pre-drying stage and a post-drying stage based on the ambient humidity value. In the post-drying stage, intermittent high and low speed airflow impacts the garments, which are in a high position and about to fall, to stretch and remove wrinkles. At low speeds, the airflow experiences a pressure drop due to the cooling of the evaporator, reducing the air pressure inside the drum. After speeding up, the impact force of the airflow entering the drum increases significantly, and since the garments are in a high position and about to fall, the airflow impacts the garments as they fall, removing wrinkles. The dried garments are refreshed, eliminating the need for users to stretch and smooth them after removing them. This meets users' higher-level garment drying needs, enhances the wrinkle removal effect of the washing and drying equipment, improves the drying efficiency, shortens the drying time, enhances the user experience, reduces energy consumption, and strengthens the product competitiveness of the washing and drying equipment.

[0042] Example 2

[0043] This embodiment provides a garment stretching and wrinkle removal system. The garment stretching and wrinkle removal system provided in this embodiment can execute the garment stretching and wrinkle removal method provided in this embodiment, and has the corresponding functional modules and beneficial effects of the method.

[0044] like Figure 2 As shown, the garment stretching and wrinkle removal system includes a humidity detection module 301, a time period division module 302, and an airflow impact module 303. The humidity detection module 301 acquires the ambient humidity value of the washing and drying equipment. The time period division module 302 divides the garment drying process into a pre-drying stage and a post-drying stage, using the ambient humidity value as a node. The airflow impact module 303, in the post-drying stage, uses intermittent high- and low-speed airflow to impact the garments, which are in a high position and about to fall, to stretch and remove wrinkles. Specifically, the humidity detection module 301 can be a humidity sensor, and the time period division module 302 can be an integration of a comparison module and a timing module. The airflow impact module 303 can be part of the control board of the drying fan, controlling the motor speed of the drying fan and the airflow speed in the duct. Based on the humidity data from the humidity detection module 301, the time period division module 302 divides the drying time periods, and then the control module 304 controls the airflow impact module 303 to use intermittent high- and low-speed airflow to impact the garments, which are in a high position and about to fall, to stretch and remove wrinkles.

[0045] First, the ambient humidity value of the washer-dryer is obtained through the humidity detection module 301. Then, the time period division module 302 divides the clothes drying process into a pre-drying stage and a post-drying stage based on the ambient humidity value of the washer-dryer. In the post-drying stage, the airflow impact module 303 uses intermittent high and low speed airflow to impact the clothes that are in a high position and about to fall, in order to stretch and remove wrinkles. At low speed, the airflow experiences a pressure drop due to the cooling of the evaporator, and the air pressure inside the drum decreases. After speeding up, the impact force of the airflow entering the drum increases significantly, and the clothes are in a high position and about to fall. When the clothes fall, the airflow impacts the clothes and removes wrinkles. The dried clothes are brand new, without the need for the user to stretch and stretch the clothes after taking them out. This meets the user's higher level of clothes drying needs, enhances the wrinkle removal effect of the washer-dryer, improves the drying efficiency of the washer-dryer, shortens the drying time of the washer-dryer, improves the user experience, reduces the energy consumption of the washer-dryer, and enhances the product competitiveness of the washer-dryer.

[0046] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the above-described division of functional modules is merely an example. In practical applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device can be divided into different functional modules to complete all or part of the functions described above. The specific working process of the functional modules described above can be referred to the corresponding process in the foregoing method embodiments, and will not be repeated here.

[0047] The garment stretching and wrinkle removal system provided in this embodiment first obtains the ambient humidity value of the washing and drying equipment, and then divides the garment drying process into a pre-drying stage and a post-drying stage based on the ambient humidity value. In the post-drying stage, intermittent high and low speed airflow impacts the garments, which are in a high position and about to fall, to stretch and remove wrinkles. At low speeds, the airflow experiences a pressure drop due to the cooling of the evaporator, reducing the air pressure inside the drum. After speeding up, the impact force of the airflow entering the drum increases significantly, and since the garments are in a high position and about to fall, the airflow impacts the garments as they fall, removing wrinkles. The dried garments are brand new, eliminating the need for users to stretch and fluff them after removing them. This meets users' higher-level garment drying needs, enhances the wrinkle removal effect of the washing and drying equipment, improves the drying efficiency, shortens the drying time, enhances the user experience, reduces energy consumption, and strengthens the product competitiveness of the washing and drying equipment.
