[0020] Traditional drying control method, drying program is fixed, resulting in uneven heat transfer due to clothes accumulation or sticking to the barrel in the drying process, prolonging the drying time and increasing energy consumption.

[0021] Based on this, the following embodiments are proposed.

[0022] Embodiment one: As shown in Figures 1-4 The present embodiment provides a clothes drying control method, the method comprising: Obtaining image information of the clothes during the rotation of the clothes treatment barrel at a preset speed for at least one revolution; According to the image information, the clothes movement state parameter is determined; Determine the clothes unfolding state based on the clothes movement state parameter; According to the clothes unfolding state, dynamic drying control is carried out; Wherein, based on the clothes movement state parameter includes: clothes height information and clothes area information of the clothes in the process of the clothes treatment barrel rotating one revolution, the clothes height information is the highest height that the clothes as a whole can reach in the process of the clothes treatment barrel rotating, and the clothes area information is the surface area of the clothes as a whole in the process of the clothes treatment barrel rotating; The clothes area information includes the maximum change difference of the clothes area, and the maximum change difference of the clothes area is the difference between the maximum value and the minimum value of the clothes area obtained by the clothes treatment barrel rotating one revolution; The clothes unfolding state includes: fully unfolded state and insufficiently unfolded state; The clothes unfolding state is determined based on the clothes movement state parameter, comprising: In the process of the clothes rotating in the clothes treatment barrel, if the highest height reaches the preset height and the maximum change difference of the clothes area is less than or equal to the preset threshold, it is determined that the clothes unfolding state is fully unfolded state; if the highest height reaches the preset height and the maximum change difference of the clothes area is greater than the preset threshold, it is determined that the clothes unfolding state is insufficiently unfolded state.

[0023] Specifically, the clothes unfolding state also includes: winding state; The clothes unfolding state is determined based on the clothes movement state parameter, comprising: If the highest height does not reach the preset height in the process of the clothes treatment barrel rotating, it is determined that the clothes unfolding state is insufficiently unfolded state; If the highest height does not reach the preset height in the process of the clothes treatment barrel rotating for multiple times, it is determined that the clothes unfolding state is winding state.

[0024] In this embodiment, the motion state parameter of the clothes is collected, wherein the motion state parameter reflects the state of the clothes under the driving of the clothes treatment barrel. For example, the clothes treatment barrel drives the clothes to rotate at a certain speed, and the clothes falls from a high point under the action of gravity when rotating with the clothes treatment barrel. The clothes unfolding state determination method can capture the height at which the clothes are thrown by the clothes treatment barrel through a high-precision camera, thereby collecting the motion state parameter of the clothes. Through the motion state parameter of the clothes, it can be indicated whether the clothes are in a winding state or a preliminary unfolding state. For example, if the highest height at which the clothes are thrown in the clothes treatment barrel is low and does not reach the preset height, it means that the clothes have not been unfolded or the clothes are in a winding state. In this state, the clothes cannot obtain a good drying effect. Conversely, if the highest height at which the clothes are thrown in the clothes treatment barrel is high and reaches the preset height, it means that the clothes reach a preliminary unfolding state, i.e., an unwinding state. In this state, the clothes can obtain a relatively good drying effect.

[0025] In this embodiment, the clothes area can be a clothes area maximum change difference value, which is the difference between the maximum value and the minimum value of the clothes area obtained by one rotation of the clothes treatment barrel. The maximum value and the minimum value of the clothes area are combined with the highest height of the clothes to further determine the clothes unfolding state. When the highest height reaches the preset height during the rotation of the clothes treatment barrel, it indicates that the clothes have reached a preliminary unfolding state and are not wound. Further determination of the clothes unfolding state through the clothes area maximum change difference value can obtain a more accurate clothes unfolding state. Under the condition that the highest height reaches the preset height, if the clothes area maximum change difference value is less than or equal to a preset threshold, it indicates that the clothes area maximum change difference value is small, and the difference between the maximum value and the minimum value of the clothes area obtained by one rotation of the clothes treatment barrel is close. Therefore, it is determined that the clothes have been fully unfolded, and the clothes unfolding state is a fully unfolded state. Conversely, if the clothes area maximum change difference value is greater than the preset threshold, it indicates that the clothes area maximum change difference value is large, and the difference between the maximum value and the minimum value of the clothes area obtained by one rotation of the clothes treatment barrel is large. Therefore, it is determined that the clothes unfolding state is an insufficiently unfolded state.

[0026] Therefore, the clothes drying control method can provide more accurate data support for clothes drying by acquiring image information of the clothes during rotation of the clothes treatment barrel for at least one revolution, determining a clothes movement state parameter according to the image information, determining a clothes unfolding state based on the clothes movement state parameter, and determining the clothes unfolding state according to the movement state parameter by collecting the movement state parameter of the clothes related to the rotation speed of the clothes treatment barrel. According to the clothes drying method, the clothes can be maintained in a fully unfolded state in the clothes treatment barrel in a manner of adjusting the rotation speed of the clothes treatment barrel according to different states of the clothes, so that the clothes can better contact hot air in the clothes treatment barrel and be better dried, thereby improving the drying efficiency of the clothes and reducing the drying time and energy consumption.

[0027] Optionally, in an implementation manner of the embodiment, as shown in Figure 5 The clothes unfolding state further includes an over-unfolding state. The clothes movement state parameter includes at least one of a clothes area maximum change difference, a clothes area minimum change difference, a clothes area average change difference, a clothes area maximum change rate, a clothes area minimum change rate, and a clothes area average change rate. If the clothes area maximum change difference of a previous week is greater than the clothes area maximum change difference of a next week in a continuous multiple-week rotation process of the clothes treatment barrel, it is determined that the clothes unfolding state is an over-unfolding state.

[0028] In the embodiment, when the clothes unfolding state is unfolded, to further optimize the drying effect, the control mainboard controls the clothes treatment barrel to rotate at the current rotation speed. The high-precision camera first captures the overall area of the clothes in the clothes treatment barrel during one rotation of the clothes treatment barrel, and obtains a previous difference in a group of pictures. The high-precision camera second captures the overall area of the clothes in the clothes treatment barrel during one rotation of the clothes treatment barrel, and obtains a next difference in a group of pictures. At this time, the control mainboard compares the previous difference with the next difference, and determines the change of the unfolding degree of the clothes during rotation according to the comparison result. The control mainboard judges the change to determine whether to adjust the current rotation speed. The clothes can be unfolded as much as possible during rotation, the surface of the clothes is more flat, the probability of deformation of the clothes is reduced, and the service life of the clothes is improved.

[0029] ​If the maximum change difference of the clothes area of the previous week is greater than the maximum change difference of the clothes area of the next week, it is determined that the clothes are in an over-expanding state, and the clothes will be damaged if they are in this state for a long time. At this time, the control mainboard reduces the current speed, the centrifugal force on the clothes decreases, and the clothes are dried continuously by being separated from the over-expanding state; if the maximum change difference of the clothes area of the previous week is less than or equal to the maximum change difference of the clothes area of the next week, it is determined that the clothes are in a moderate-expanding state, and the clothes are in contact with the drying air in this state. At this time, the control mainboard appropriately increases the current speed, so that the clothes are maintained in this state with good expansion, thereby improving the drying efficiency of the clothes. In this state, the speed can also be appropriately reduced according to the decreasing weight of the clothes, so that the clothes are maintained in a state of running close to the wall, that is, the clothes are maintained in a state of being fully expanded, thereby maintaining the clothes to be continuously and efficiently dried.

[0030] Optionally, in an implementation manner of the embodiment, as shown in Figure 2 The method further includes: inputting the image information into a feature recognition model to obtain the clothes movement state parameter output by the feature recognition model; The feature recognition model is trained in the following manner: obtaining target image information pre-set with a training label, and taking the target image information as model input data; taking the model input data as input, comparing the training label and the target clothes movement state parameter corresponding to the output of the feature recognition model, and training the feature recognition model based on the difference between the target clothes movement state parameter and the training label.

[0031] In the embodiment, the highest height is obtained in the following manner: a plurality of first image information is obtained during rotation of the clothes treatment barrel for at least one revolution, a plurality of clothes height information is obtained according to the plurality of first image information, and the highest height is obtained from the plurality of clothes height information.

[0032] The difference is obtained in the following manner: one or more sets of second image information are obtained during rotation of the clothes treatment barrel for at least one revolution, a maximum value and a minimum value of one or more sets of clothes area are obtained according to the one or more sets of second image information, and one or more differences are obtained from the maximum value and the minimum value of the one or more sets of clothes area.

[0033] ​Regarding the clothes area: can refer to the surface area of the clothes in direct contact with the inner wall of the clothes treatment barrel or water flow, which can be detected by a pressure sensor array or an optical reflection sensor. In a drum washing machine, piezoelectric film sensors (such as PVDF material) arranged along the barrel wall can measure the contact pressure distribution of the clothes distribution in real time, and the clothes area can be obtained by integral calculation.

[0034] It can also refer to: the projected unfolded area of the clothes, which refers to the two-dimensional projected area of the clothes in the direction perpendicular to the rotation axis, which can be detected by an infrared light curtain scan or a top camera. A linear CCD sensor (such as a 2048-pixel array) installed on the barrel cover is used to scan the shadow profile of the rotating clothes at a sampling frequency of 100Hz, and the real-time projected area is calculated by image processing algorithm.

[0035] Optionally, in an implementation manner of the embodiment, as shown in Figure 7 The preset height is equal to the radius of the inner barrel of the clothes treatment barrel.

[0036] In the embodiment, the control mainboard first controls the clothes treatment barrel in the clothes treatment device to rotate at a first rotating speed, at this time, the clothes treatment barrel drives the clothes to rotate together, and the clothes will fall from a high point under the action of gravity when rotating with the clothes treatment barrel. The height of the clothes being thrown is obtained by a high-precision camera. If the highest height of the clothes being thrown in the clothes treatment barrel does not exceed the radius value R of the inner barrel, it means that the clothes have not been fully unfolded. The clothes in this state cannot obtain a better drying effect. At this time, the control mainboard controls the clothes treatment barrel to continuously adjust the rotating speed of the motor, and increases the rotating speed of the motor until the control mainboard detects that the highest height of the clothes being thrown in the clothes treatment barrel exceeds the radius value R of the inner barrel, which means that the clothes have been fully unfolded. At this time, the next adjustment stage can be entered. If the highest height of the clothes being thrown in the clothes treatment barrel exceeds the radius value of the inner barrel, it means that the clothes have been fully unfolded. At this time, the control mainboard can control the clothes treatment barrel to maintain the current rotating speed of the motor to continue rotating, and directly enter the next adjustment stage.

[0037] The preset height can also be a preset height value obtained from experimental data or model output other than the radius value of the inner barrel.

[0038] Optionally, in an implementation manner of the embodiment, The image information of the clothes during the rotation of the clothes treatment barrel for at least one revolution includes: The image information of the highest height and the difference value is obtained by an image acquisition device located at the barrel opening of the clothes treatment barrel and facing the inside of the barrel.

[0039] ​In this embodiment, for example, the clothes treatment device is a drum washing machine, and the image acquisition device includes two high-precision cameras, one of which is located above the glass bowl and captures the highest height of the clothes in the clothes treatment barrel from the barrel opening, and the other is located below the glass bowl and captures the area of the clothes in the clothes treatment barrel from the barrel opening.

[0040] Optionally, in an implementation manner of the embodiment, the clothes treatment device is a drum washing machine, and the image acquisition device includes two high-precision cameras, one of which is located above the glass bowl and captures the highest height of the clothes in the clothes treatment barrel from the barrel opening, and the other is located below the glass bowl and captures the area of the clothes in the clothes treatment barrel from the barrel opening. The insufficiently unfolded state includes a winding state and a non-winding state. The dynamic drying control according to the clothes unfolding state includes: If it is determined that the clothes unfolding state is the insufficiently unfolded state and is in the non-winding state, the motor is controlled to increase the rotating speed. If it is determined that the clothes unfolding state is the insufficiently unfolded state and is in the winding state, the motor is controlled to reverse and decrease the rotating speed.

[0041] Further, if it is determined that the clothes unfolding state is the over-unfolded state, the motor is controlled to decrease the rotating speed so that the clothes remain in the wall-attached running state in the drying process.

[0042] In this embodiment, the clothes movement state parameter is acquired, wherein the movement state parameter reflects the state of the clothes driven by the clothes treatment barrel. For example, the clothes treatment barrel drives the clothes to rotate at a certain rotating speed, and the clothes fall from a high point under the action of gravity when the clothes rotate with the clothes treatment barrel. The clothes unfolding state determination method can detect the height at which the clothes are thrown by the clothes treatment barrel through a sensor, thereby acquiring the movement state parameter of the clothes. Through the clothes movement state parameter, the unfolding state of the clothes can be indicated. For example, if the highest height at which the clothes are thrown in the clothes treatment barrel is low, it indicates that the clothes have not been fully unfolded. The clothes in this state cannot obtain good drying effect. That is, when the highest height of the clothes does not reach the preset height, the clothes are in the insufficiently unfolded state. By increasing the rotating speed of the clothes treatment barrel, the clothes unfolding state is adjusted so that the clothes are fully unfolded, thereby improving the drying effect and drying efficiency.

[0043] Conversely, if the highest height at which the clothes are thrown in the clothes treatment barrel is high, it indicates that the clothes are fully unfolded. In the fully unfolded state, the clothes can obtain good drying effect. The rotating speed of the clothes treatment barrel is not adjusted, or is slightly decreased according to the decrease of the weight of the clothes, so that the clothes remain in the wall-attached running state in the drying process, which can make the clothes have better drying effect and higher drying efficiency.

[0044] For example, the maximum and minimum values of the clothing area are combined with the maximum height of the clothing to further determine the clothing unfolding state. When the maximum height reaches a preset height during the rotation of the clothing treatment barrel, it indicates that the clothing has reached a preliminary unfolding state and is not entangled. Further determining the clothing unfolding state by the maximum change difference of the clothing area can obtain a more accurate clothing unfolding state. When the maximum height reaches the preset height, if the maximum change difference of the clothing area is less than or equal to a preset threshold, it indicates that the maximum change difference of the clothing area is small, and the difference between the maximum and minimum values of the clothing area obtained by one rotation of the clothing treatment barrel is close. It is determined that the clothing has been fully unfolded, and the clothing unfolding state is a fully unfolded state. In the fully unfolded state, the clothing can obtain a better drying effect. The rotation speed of the clothing treatment barrel is not adjusted, or the rotation speed is slightly reduced according to the decrease of the clothing weight, so that the clothing can maintain a wall-attached running state during the drying process, thereby improving the drying effect and the drying efficiency of the clothing.

[0045] Conversely, if the maximum change difference of the clothing area is greater than the preset threshold, it indicates that the maximum change difference of the clothing area is large, and the difference between the maximum and minimum values of the clothing area obtained by one rotation of the clothing treatment barrel is large. It is determined that the clothing unfolding state is an insufficiently unfolded state and is in the non-entangled state. The rotation speed of the motor is controlled to be increased, so that the clothing has a large unfolding area and is in full contact with the drying air, thereby improving the drying effect and the drying efficiency.

[0046] If the maximum height does not reach the preset height during the continuous rotation of the clothing treatment barrel for multiple rotations, it is determined that the clothing unfolding state is the insufficiently unfolded state and is in the entangled state. The motor is controlled to be reversed and the rotation speed is reduced to perform the disentangling treatment on the clothing. The rotation speed of the motor is continuously monitored. If the rotation speed of the motor does not change, it indicates that the disentangling fails, and the motor is controlled to stop working. The clothing needs to be manually disentangled. By setting the disentangling stage in the control method, the clothing treatment device can automatically determine the clothing in the entangled state. The maximum height acquisition of the clothing in the entangled state in the clothing treatment barrel is repeatedly performed, the drying running time of the clothing is shortened, and the clothing can quickly enter the fully unfolded state, thereby further improving the drying efficiency of the clothing.

[0047] Therefore, the drying control method provided by the embodiment can provide more accurate data support for the drying of the clothing by determining the clothing unfolding state. According to the adjustment of the rotation speed of the clothing treatment barrel according to the different unfolding states of the clothing, the clothing can be maintained in a fully unfolded state in the clothing treatment barrel, the clothing can maintain a wall-attached running state during the drying process, the clothing can better contact the hot air in the clothing treatment barrel, and the drying efficiency of the clothing is improved, and the drying time and the drying energy consumption are reduced.

[0048] Optionally, in an implementation manner of the embodiment, as shown in Figure 6 The process of dynamically controlling the drying according to the unfolding state of the clothes includes: Controlling the rotating speed of the motor according to the unfolding state of the clothes, and detecting the change of the clothes area information in real time during the control of the rotating speed of the motor; Comparing the maximum change difference Δs of the clothes area detected each time with the maximum change difference Δs-1 of the clothes area detected last time; If Δs-1 < Δs, the rotating speed of the motor is increased; If Δs-1 ≥ Δs, the rotating speed of the motor is decreased.

[0049] In the embodiment, to further optimize the drying effect, the maximum change difference Δs of the clothes area detected each time is compared with the maximum change difference Δs-1 of the clothes area detected last time, and the rotating speed of the motor is adjusted according to the comparison result.

[0050] Specifically, if Δs-1 < Δs, the rotating speed of the motor is increased; in this state, it is indicated that the clothes are in a good unfolding state at the current rotating speed, and the clothes are in sufficient contact with the drying air in this state, at this time, the control mainboard appropriately increases the current rotating speed, so that the clothes are maintained in this good unfolding state, thereby improving the drying efficiency of the clothes.

[0051] If Δs-1 ≥ Δs, the rotating speed of the motor is decreased: it is indicated that the clothes are in an over-unfolding state at the current rotating speed, and the clothes will be damaged if they are in this state for a long time, at this time, the control mainboard decreases the current rotating speed, the centrifugal force acting on the clothes is reduced, and the clothes are separated from the over-unfolding state to continue to be dried.

[0052] The clothes drying control method enables the clothes treatment barrel to adjust the rotating speed according to the change of the maximum change difference of the clothes area, enables the clothes to be unfolded as much as possible in rotation, enables the surface of the clothes to be more flat, reduces wrinkles, reduces the probability of deformation of the clothes, improves the service life of the clothes, and enables the clothes treatment device to automatically adjust the current rotating speed of the clothes treatment barrel, thereby shortening the drying time of the clothes.

[0053] Embodiment Two The embodiment provides an electronic device, which includes: a memory storing computer instructions; a processor configured to invoke and execute the computer instructions to implement the clothes drying control method in the embodiment one.

[0054] ​In this embodiment, the electronic device includes a memory and a processor, the memory is used to store computer instructions, and the processor is used to call and execute the computer instructions, so that the clothes drying control method in embodiment one is implemented. Since the electronic device can execute the clothes drying control method in embodiment one, the electronic device has all the beneficial effects of the clothes drying control method in embodiment one, which will not be repeated here.

[0055] Embodiment three This embodiment provides a clothes treatment device, which uses the drying control method in embodiment one or includes the electronic device in embodiment two.

[0056] In this embodiment, the clothes treatment device can be a drum washing machine or other device capable of drying clothes. The clothes treatment device can directly execute the drying control method in embodiment one to dry clothes, or the electronic device in embodiment two can be provided on the clothes treatment device, and the drying control method in embodiment one can be executed through the electronic device in embodiment two to dry clothes. Since the clothes treatment device can directly execute the drying control method in embodiment one or is provided with the electronic device in embodiment two, the clothes treatment device has all the beneficial effects of the drying control method in embodiment one or the electronic device in embodiment two, which will not be repeated here.

[0057] Preferably, the sensor in the clothes treatment device includes an image module and an identification module, under the joint cooperation of the image module and the identification module, the clothes in the clothes drying process can be identified by an artificial intelligence model, and the different states of the clothes in the drying process can also be identified and the identification results can be fed back to the motor to control the speed. The main responsibility of the image module is to capture and record the state of the clothes in the washing and protecting machine barrel. This process is completed by a high-precision camera, which ensures that every detail of the clothes can be clearly captured, for example, the image module will take multiple pictures in each rotation of the clothes treatment barrel, and try to take pictures of the clothes in different positions in the clothes treatment barrel. At the same time, the identification module is built-in a deeply trained artificial intelligence model, which is specially used to analyze and interpret the photos taken by the image module. The model can accurately identify the state of the clothes and feed back the information to the control mainboard, so that the control mainboard can adjust the speed of the clothes treatment barrel according to the specific situation of the clothes, so as to ensure that the clothes always maintain an unfolded state during the drying process, increase the contact area of the clothes and hot air, and thus improve the drying effect. When the clothes treatment device starts the drying program, the control mainboard will first check whether the motor speed reaches the preset v1. During the operation of the clothes treatment device, the control mainboard will take a picture of the clothes in the clothes treatment barrel every certain time ΔT1 in each single rotation period T1. Then, the image module transmits these pictures to the identification module for analysis by the deployed artificial intelligence model, and extracts the key feature information of the clothes, including the overall area S of all clothes and the height H of the clothes thrown by the clothes treatment barrel. In a single rotation period, these feature information will be marked as a series of numerical values, such as clothes area S1, S2, S3……Si, and clothes height H1, H2, H3……Hi.

[0058] There are two key points in the drying process of clothes. The first key point is to confirm that the height value of the clothes in the parabolic motion to the highest point is as high as possible through image recognition, so that the falling distance of the clothes in the clothes treatment barrel is the longest, which can make the clothes better unfolded, increase the contact area with the drying air, and improve the drying effect of the clothes. The second point is that as time goes on, the clothes will gradually dry, and the weight of the clothes will gradually decrease, and the position of the clothes in the parabolic motion has a close relationship with the weight of the clothes. When the clothes gradually dry, the position of the clothes in the parabolic motion will certainly change, and the falling distance of the clothes in the clothes treatment barrel will be less than that when the clothes are wet. By dynamically adjusting the speed of the clothes treatment barrel through image recognition, the clothes can be fully unfolded. Therefore, the control mainboard can choose to capture the position of the clothes in the clothes treatment barrel during one rotation by the longer time period relative to the forward rotation when the clothes are reversed (limited by the shutter speed of the camera), to reflect the movement of the clothes in the barrel.

[0059] Next, the control board will comprehensively analyze these data. If the maximum height of the clothes Hmax in a group of pictures is lower than the radius of the clothes processing barrel Hr, it means that the clothes cannot be fully unfolded. At this time, the control board will automatically adjust the motor speed to rise to v2, where v2 is greater than v1. The motor rotating at the speed of v2 can promote the better unfolding of the clothes. If the maximum height of the clothes Hmax is still lower than the radius of the clothes processing barrel Hr found by continuous detection for several times, the control board will judge that the clothes are in a state of entanglement or clumping, and take corresponding measures to untangle, and then continue to identify and adjust the state of the clothes unfolding. Our purpose is to make the clothes fall from the highest point in the clothes processing barrel, so the motion trajectory when it falls is a parabola. If the height is too high, it will cause the clothes to hit the clothes processing barrel when it moves in a parabolic motion. The highest point of the clothes parabolic motion is lower than the clothes processing barrel radius, which is lower than the clothes parabolic motion height higher than the clothes processing barrel radius. This will result in a shorter motion distance when the clothes fall, so the clothes cannot be fully unfolded. If the clothes are heavy, if the highest point of the clothes parabolic motion is low, these clothes can hardly be thrown up, but only roll in the clothes processing barrel, thereby greatly reducing the drying efficiency.

[0060] When the maximum height of the clothes Hmax exceeds the radius of the clothes processing barrel Hr, the control board will further analyze the change of the clothes area. By calculating the difference between the maximum value Smax and the minimum value Smin of the clothes area in a group of pictures, ΔS = Smax - Smin, it can be evaluated whether the clothes are close to the barrel wall of the clothes processing barrel, where the pictures within one revolution of the clothes processing barrel are a group. If ΔS is less than the set threshold value ΔS1, it means that the clothes may be close to the barrel wall of the clothes processing barrel. At this time, the control board will reduce the motor speed to v2 to promote the unfolding of the clothes. As the drying process advances, the humidity of the clothes gradually decreases, and the value of ΔS will also change accordingly. Therefore, throughout the drying process, the control board will continuously monitor the state of the clothes unfolding until the end of the drying.

[0061] In order to further optimize the drying effect, the control board adopts the method of dynamically adjusting the motor speed. Specifically, the difference ΔSi detected each time is compared with the previous difference ΔSi-1. If ΔSi-1 is less than ΔSi, it means that the degree of clothes unfolding has improved, and at this time the control board will appropriately increase the motor speed to v3, where v3 equals (v3 = v2 - Δv), to maintain a good unfolding state; otherwise, if ΔSi-1 is greater than ΔSi, it means that the clothes may be too unfolded, and the control board will reduce the motor speed to avoid damage to the clothes caused by excessive unfolding. Through this dynamic adjustment strategy, the control board can continuously optimize the unfolding state of the clothes throughout the drying process, thereby achieving the best drying effect.

[0062] Finally, when the laundry treatment apparatus completes drying and determines that the laundry is dry, the entire control flow is ended.

[0063] In this preferred embodiment, ΔT1 is the time interval for the camera to take a photo, which is a time interval sufficient to clearly capture the trajectory of the laundry in one rotation, so that the image recognition is more accurate, v1 is the rotational speed at the start of drying in the normal washing machine program logic, v2 is the rotational speed that is conducive to the unfolding of the laundry, and at this rotation, it is determined whether the laundry is unfolded, Δv is a step value, which is used to adjust the unfolding state of the laundry, and needs to be obtained through specific experiments according to different models, and ΔS1 is a value indicating that the laundry is just attached to the barrel, which is used to determine whether the laundry is attached to the barrel.

[0064] In summary, the ingenious idea of the laundry drying control method is that: By acquiring image information of the laundry in the process of rotating the laundry treatment barrel for at least one rotation, determining a laundry movement state parameter according to the image information, and determining a laundry unfolding state based on the laundry movement state parameter, the movement state parameter of the laundry related to the rotational speed of the laundry treatment barrel is collected, and the laundry unfolding state is determined according to the movement state parameter, which can provide more accurate data support for the drying of the laundry, and the rotational speed of the laundry treatment barrel can be adjusted according to different unfolding states of the laundry, so that the laundry can be maintained in a fully unfolded state in the laundry treatment barrel, the laundry can be better contacted with the hot air in the laundry treatment barrel, and the laundry can be better dried, so as to improve the drying efficiency of the laundry, reduce the drying time and drying energy consumption.
