For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0055] The conventional drying control method has fixed drying program, which causes uneven heat transfer due to clothes accumulation or sticking to the barrel during drying process, prolongs the drying time and increases energy consumption.

[0056] Based on this, the following embodiments are proposed.

[0057] Embodiment one:

[0058] As shown in Figures 1-4 The present embodiment provides a clothes drying control method, which comprises:

[0059] Obtaining image information of the clothes during the rotation of the clothes treatment barrel at a preset speed for at least one revolution;

[0060] Determining a clothes movement state parameter according to the image information;

[0061] Determining a clothes unfolding state based on the clothes movement state parameter;

[0062] Performing dynamic drying control according to the clothes unfolding state;

[0063] Wherein, the clothes movement state parameter includes clothes height information and clothes area information of the clothes during the rotation of the clothes treatment barrel for one revolution, the clothes height information is the maximum height that the clothes as a whole can reach during the rotation of the clothes treatment barrel, and the clothes area information is the surface area of the clothes as a whole during the rotation of the clothes treatment barrel;

[0064] The clothes area information includes a clothes area maximum change difference, and the clothes area maximum change difference is the difference between the maximum value and the minimum value of the clothes area obtained by the rotation of the clothes treatment barrel for one revolution;

[0065] The clothes unfolding state includes: a fully unfolded state and an insufficiently unfolded state.

[0066] The clothes unfolding state is determined based on the clothes movement state parameter.

[0067] In the process of the clothes rotating in the clothes treatment barrel, if the highest height reaches the preset height and the maximum clothes area change difference is less than or equal to the preset threshold, it is determined that the clothes unfolding state is a fully unfolded state; if the highest height reaches the preset height and the maximum clothes area change difference is greater than the preset threshold, it is determined that the clothes unfolding state is an insufficiently unfolded state.

[0068] Specifically, the clothes unfolding state further includes: a winding state.

[0069] The clothes unfolding state is determined based on the clothes movement state parameter.

[0070] If, in the process of the clothes treatment barrel rotating, it is detected that the highest height does not reach the preset height, it is determined that the clothes unfolding state is an insufficiently unfolded state.

[0071] If, in the process of the clothes rotating in the clothes treatment barrel for multiple consecutive rotations, the highest height does not reach the preset height, it is determined that the clothes unfolding state is a winding state.

[0072] In this embodiment, the clothes movement state parameter is collected, 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 speed, and the clothes fall 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 clothes movement state parameter. Through the clothes movement state parameter, 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 indicates 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 indicates 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.

[0073] In this embodiment, the clothing area can be a clothing area maximum change difference, which is the difference between the maximum value and the minimum value of the clothing area obtained by rotating the clothes processing barrel for one revolution; the maximum value and the minimum value of the clothing area are combined with the maximum height of the clothing to further determine the clothing unfolding state. In the process of rotating the clothes processing barrel, when the maximum height reaches the preset height, it indicates that the clothing has reached a preliminary unfolded state and is not wound. Further, by determining the clothing unfolding state through the clothing area maximum change difference, a more accurate clothing unfolding state can be obtained. Under the condition that the maximum height reaches the preset height, if the clothing area maximum change difference is less than or equal to a preset threshold, it indicates that the clothing area maximum change difference is small, and the difference between the maximum value and the minimum value of the clothing area obtained by rotating the clothes processing barrel for one revolution is small, then it is determined that the clothing has been fully unfolded, and the clothing unfolding state is a fully unfolded state; otherwise, if the clothing area maximum change difference is greater than the preset threshold, it indicates that the clothing area maximum change difference is large, and the difference between the maximum value and the minimum value of the clothing area obtained by rotating the clothes processing barrel for one revolution is large, then it is determined that the clothing unfolding state is an insufficiently unfolded state.

[0074] Therefore, the clothing drying control method can provide more accurate data support for clothing drying by acquiring image information of the clothing in the process of rotating the clothes processing barrel for at least one revolution, determining the clothing motion state parameter according to the image information, and determining the clothing unfolding state based on the clothing motion state parameter. According to the way of adjusting the rotating speed of the clothes processing barrel according to the different states of the clothing, the clothing can be maintained in a fully unfolded state in the clothes processing barrel, the clothing can better contact with the hot air in the clothes processing barrel, and the clothing can be better dried, so as to improve the drying efficiency of the clothing, reduce the drying time and drying energy consumption.

[0075] Optionally, in an implementation manner of the embodiment, as shown in Figure 5

[0076] The clothing unfolding state further includes an over-unfolded state.

[0077] The determining of the clothing unfolding state based on the clothing motion state parameter further includes:

[0078] If the clothing area maximum change difference of the previous week is greater than the clothing area maximum change difference of the next week in the process of continuously rotating the clothes processing barrel for multiple weeks, it is determined that the clothing unfolding state is an over-unfolded state.

[0079] ​In the embodiment, under the condition that the clothes unfolding state is unfolded, to further optimize the drying effect, the mainboard controls the clothes treatment drum to rotate at the current rotating speed, the high-precision camera shoots the total area of all clothes for the first time in the process of one rotation of the clothes treatment drum, and obtains the difference before in a group of pictures, the high-precision camera rotates the clothes treatment drum again for one rotation, and the total area of all clothes is shot for the second time, and the difference after in a group of pictures is obtained, at this time the mainboard compares the difference before and the difference after, and determines the change of the unfolding degree of the clothes in rotation according to the comparison result between the two, and the mainboard judges the change to determine whether to adjust the current rotating speed. The clothes can be unfolded as much as possible in 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.

[0080] If the maximum change difference of the clothes area of the previous cycle is greater than the maximum change difference of the clothes area of the next cycle, it is determined that the clothes unfolding state is an over-unfolding state, and the clothes will be damaged in this state for a long time. At this time, the mainboard reduces the current rotating speed, the centrifugal force received by the clothes is reduced, the clothes are separated from the over-unfolding state and thus continue to be dried; If the maximum change difference of the clothes area of the previous cycle is less than or equal to the maximum change difference of the clothes area of the next cycle, it is determined that the clothes unfolding state is a moderate-unfolding state, and the clothes in this state are in sufficient contact with the drying air. At this time, the 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. In this state, the rotating speed can also be appropriately reduced as the weight of the clothes decreases, so that the clothes are maintained in the wall-attached running state, that is, the fully-unfolding state, thereby maintaining the clothes to be continuously and efficiently dried.

[0081] Optionally, in an implementation manner of the embodiment, as shown in Figure 2 ,

[0082] The method further includes:

[0083] inputting the image information into a feature recognition model to obtain the clothes movement state parameter output by the feature recognition model;

[0084] The feature recognition model is trained in the following manner:

[0085] obtaining target image information provided with a training label in advance, and taking the target image information as model input data;

[0086] The model input data is taken as input, the target clothing movement state parameter corresponding to the output of the feature recognition model is compared with the training label, and the feature recognition model is trained based on the difference between the target clothing movement state parameter and the training label.

[0087] In this embodiment, the highest height acquisition method includes: acquiring a plurality of first image information during the rotation of the clothes processing barrel for at least one revolution, obtaining a plurality of clothes height information according to the plurality of first image information, and obtaining the highest height from the plurality of clothes height information.

[0088] The difference value acquisition method includes: acquiring one or more sets of second image information during the rotation of the clothes processing barrel for at least one revolution, obtaining one or more sets of maximum and minimum values of the clothes area according to the one or more sets of second image information, and obtaining one or more difference values from the one or more sets of maximum and minimum values of the clothes area.

[0089] Regarding the clothes area: it can refer to the surface area of the clothes directly contacting the inner wall of the clothes processing barrel or the 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.

[0090] It can also refer to: the projection area of the clothes, which refers to the two-dimensional projection 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 projection area is calculated by image processing algorithm.

[0091] Optionally, in an implementation manner of the embodiment, as shown in Figure 7

[0092] The preset height is equal to the radius of the inner barrel of the clothes processing barrel.

[0093] ​In this embodiment, the control mainboard first controls the laundry treatment drum in the laundry treatment equipment to rotate at a first rotating speed. At this time, the laundry treatment drum drives the laundry to rotate together. The laundry will fall from a high point under the action of gravity. The height at which the laundry is thrown is obtained by a high-precision camera. If the highest height at which the laundry is thrown in the laundry treatment drum does not exceed the radius value R of the inner drum, it indicates that the laundry has not been fully unfolded. The laundry in this state cannot obtain a better drying effect. At this time, the control mainboard controls the laundry treatment drum 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 at which the laundry is thrown in the laundry treatment drum exceeds the radius value R of the inner drum, which indicates that the laundry has been fully unfolded. At this time, the next adjustment stage can be entered. If the highest height at which the laundry is thrown in the laundry treatment drum exceeds the radius value of the inner drum, it indicates that the laundry has been fully unfolded. At this time, the control mainboard can control the laundry treatment drum to maintain the current rotating speed of the motor to continue rotating, and directly enter the next adjustment stage.

[0094] The preset height can also be a preset height value obtained according to experimental data or model output, in addition to the radius value of the inner drum.

[0095] Optionally, in an implementation manner of the embodiment, the control mainboard controls the laundry treatment drum to rotate at a first rotating speed, and controls the laundry treatment drum to rotate at a second rotating speed after the laundry treatment drum rotates at least one round.

[0096] The image information of the laundry in the process of rotating at least one round of the laundry treatment drum includes:

[0097] The image information of the highest height and the image information of the difference value are obtained by an image acquisition device located at a drum opening of the laundry treatment drum and facing the inside of the drum.

[0098] In this embodiment, for example, the laundry treatment equipment is a drum washing machine, and the image acquisition device is composed of two high-precision cameras. One high-precision camera is located above the glass bowl and photographs the highest height of the laundry facing the inside of the drum at the drum opening of the laundry treatment drum. The other high-precision camera is located below the glass bowl and photographs the area of the laundry facing the inside of the drum at the drum opening of the laundry treatment drum.

[0099] Optionally, in an implementation manner of the embodiment, the control mainboard controls the laundry treatment drum to rotate at a first rotating speed, and controls the laundry treatment drum to rotate at a second rotating speed after the laundry treatment drum rotates at least one round.

[0100] The insufficiently unfolded state includes a winding state and a non-winding state.

[0101] The dynamic drying control according to the unfolding state of the laundry includes:

[0102] If it is determined that the unfolding state of the laundry is the insufficiently unfolded state and is in the non-winding state, the rotating speed of the motor is increased.

[0103] If it is determined that the clothes unfolding state is the insufficient unfolding state and the clothes are in the entangled state, the motor is controlled to reverse and reduce the rotating speed.

[0104] Further, if it is determined that the clothes unfolding state is the over-unfolding state, the motor is controlled to reduce the rotating speed so that the clothes remain in the wall-attached running state during the drying process.

[0105] In this embodiment, the clothes movement state parameter is collected, 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 rotating 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 collecting the movement state parameter of the clothes. The clothes movement state parameter can indicate the unfolding state of the clothes. 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 a good drying effect. When the movement state parameter is the insufficient unfolding state in which the highest height of the clothes does not reach a preset height, the rotating speed of the clothes treatment barrel is increased to adjust the clothes unfolding state, so that the clothes are fully unfolded, and the drying effect and drying efficiency are improved.

[0106] 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 a good drying effect. The rotating speed of the clothes treatment barrel is not adjusted, or is slightly reduced according to the decrease in the weight of the clothes, so that the clothes remain in the wall-attached running state during the drying process, which can make the clothes have a better drying effect and a higher drying efficiency.

[0107] For another example, 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. In the process of rotating the clothes treatment barrel, when the highest height reaches a preset height, it indicates that the clothes are in a preliminary unfolded state and are not entangled. The clothes unfolding state is further determined by the maximum change difference of the clothes area, which can obtain a more accurate clothes unfolding state. Under the condition that the highest height reaches the preset height, the maximum change difference of the clothes area is less than or equal to a preset threshold, which indicates that the maximum change difference of the clothes area is small, and the difference between the maximum value and the minimum value of the clothes area obtained by rotating the clothes treatment barrel for one cycle is close. It is determined that the clothes are fully unfolded, and the clothes unfolding state is the fully unfolded state. In the fully unfolded state, the clothes can obtain a good drying effect. The rotating speed of the clothes treatment barrel is not adjusted, or is slightly reduced according to the decrease in the weight of the clothes, so that the clothes remain in the wall-attached running state during the drying process, which can make the clothes have a better drying effect and a higher drying efficiency.

[0108] Conversely, if the maximum change difference of the clothes area is greater than the preset threshold, it indicates that the maximum change difference of the clothes area is large, and the difference between the maximum value and the minimum value of the clothes area obtained by rotating the clothes treatment barrel for one revolution is large, and it is determined that the clothes unfolding state is an insufficiently unfolded state and is in the non-winding state, and the motor speed is controlled to be increased, so that the clothes have a larger unfolding area, thereby fully contacting with the drying air, and improving the drying effect and drying efficiency.

[0109] If the highest height does not reach the preset height during the continuous rotation of the clothes treatment barrel for multiple revolutions, it is determined that the clothes unfolding state is the insufficiently unfolded state and is in the winding state, the motor is controlled to be reversed and the speed is reduced, and the clothes are unwound, and the motor speed is continuously monitored at this time, and if the motor speed does not change, it indicates that the unwinding fails, and the motor is controlled to stop working, and manual unwinding is required. By setting the unwinding stage in the control method, the clothes treatment equipment can automatically judge the clothes in the entangled state, avoid repeatedly performing the highest height acquisition of the clothes in the entangled state in the clothes treatment barrel, shorten the clothes drying running time, and enable the clothes to quickly enter the fully unfolded state, thereby further improving the drying efficiency of the clothes.

[0110] Therefore, the drying control method provided by the embodiment can provide more accurate data support for the drying of the clothes by determining the clothes unfolding state, and can continuously maintain the clothes in a fully unfolded state in the clothes treatment barrel by adjusting the speed of the clothes treatment barrel according to different unfolding states of the clothes, so that the clothes can better contact with the hot air in the clothes treatment barrel during the drying process, and the clothes can be better dried, thereby improving the drying efficiency of the clothes and reducing the drying time and energy consumption.

[0111] Optionally, in an implementation manner of the embodiment, as shown in Figure 6

[0112] The process of dynamically controlling the drying according to the clothes unfolding state comprises:

[0113] The speed of the motor is controlled according to the clothes unfolding state, and the change of the clothes area information is detected in real time during the control of the speed of the motor.

[0114] 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.

[0115] If Δs-1<Δs, the speed of the motor is increased.

[0116] If Δs-1≥Δs, the speed of the motor is reduced.

[0117] ​In this embodiment, to further optimize the drying effect, the maximum change difference Δs of the detected clothes area each time is compared with the maximum change difference Δs-1 of the detected clothes area last time, and the motor is adjusted in speed according to the comparison result.

[0118] Specifically, if Δs-1< Δs, the motor speed is increased; in this state, it is indicated that the clothes are in a good state of expansion at the current speed, and the clothes are in sufficient contact with the drying air in this state, at which time the control board appropriately increases the current speed, so that the clothes are maintained in this good state of expansion, thereby improving the drying efficiency of the clothes.

[0119] If Δs-1≥ Δs, the motor speed is reduced: it is indicated that the clothes are in an over-expanded state at the current speed, and the clothes will be damaged if they are in this state for a long time, at which time the control board reduces the current speed, the centrifugal force on the clothes is reduced, and the clothes are separated from the over-expanded state to continue to be dried.

[0120] The clothes drying control method enables the clothes treatment barrel to adjust the speed according to the change of the maximum change difference of the clothes area, enables the clothes to be expanded 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 speed of the clothes treatment barrel, thereby shortening the drying time of the clothes.

[0126] Embodiment Three

[0127] The embodiment provides a clothes treatment device, which uses the drying control method in Embodiment One or comprises the electronic device in Embodiment Two.

[0129] Preferably, the sensor in the laundry treatment device includes an image module and an identification module, which can identify the laundry in the laundry drying process through an artificial intelligence model under the joint cooperation of the image module and the identification module, and can identify different states of the laundry in the drying process and feed back the identification results to the motor to control the rotating speed. The main responsibility of the image module is to capture and record the state of the laundry in the washing and treating machine drum. This process is completed by a high-precision camera, which ensures that every detail of the laundry can be clearly captured, for example, the image module will take multiple photos in each rotation of the laundry treatment drum, and try to capture the state of the laundry at different positions in the laundry treatment drum. At the same time, the identification module is built-in with an artificial intelligence model that has been deeply trained, which is specially used to analyze and interpret the photos taken by the image module. The model can accurately identify the state of the laundry and feed back the information to the control mainboard, so that the control mainboard can adjust the rotating speed of the laundry treatment drum according to the specific situation of the laundry, so as to ensure that the laundry always maintains an unfolded state in the drying process, increases the contact area of the laundry and hot air, and thus improves the drying effect. When the laundry treatment device starts the drying program, the control mainboard will first check whether the rotating speed of the motor reaches the preset v1. During the operation of the laundry treatment device, the control mainboard will take a photo of the laundry in the laundry treatment drum every certain time ΔT1 in each single rotation period T1. Subsequently, the image module transmits these photos to the identification module for analysis through the deployed artificial intelligence model, and extracts the key feature information of the laundry, including the overall area S of all the laundry and the height H of the laundry thrown by the laundry treatment drum. In the single rotation period, these feature information will be marked as a series of numerical values, such as the laundry area S1, S2, S3……Si, and the laundry height H1, H2, H3……Hi.

[0130] The clothes have two focuses during the drying process. The first focus is to confirm a height value that can make the clothes move in a parabolic motion to the highest point as high as possible through image recognition, so that the falling motion distance of the clothes in the clothes processing barrel is the longest, which can make the clothes better unfold, 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 parabolic motion starting point of the clothes has a close relationship with the weight of the clothes. When the clothes gradually dry, the starting point position of the clothes will definitely change, and the falling motion distance of the clothes in the clothes processing barrel will be less than the effect when the clothes have a larger humidity. Through image recognition, the speed of the clothes processing barrel is dynamically adjusted, so that the clothes can fully unfold. Therefore, the control mainboard can choose to capture the position of the clothes in the clothes processing barrel during one rotation by grabbing the clothes in the clothes processing barrel during the relatively long time period of reverse rotation compared with forward rotation (limited by the shutter speed of the camera), to reflect the motion state of the clothes in the barrel.

[0131] Next, the control mainboard will comprehensively analyze these data. If the maximum height Hmax of the clothes in a group of pictures is lower than the radius Hr of the clothes processing barrel, it means that the clothes have not fully unfolded, and the control mainboard 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 clothes to better unfold. If the maximum height Hmax of the clothes is still lower than the radius Hr of the clothes processing barrel for several consecutive detections, the control mainboard will judge that the clothes are in a tangled or bunched state, and take corresponding untangling measures, and then continue to identify and adjust the unfolding state of the clothes. Our goal is to make the clothes fall to the highest point in the clothes processing barrel, so the motion trajectory when it falls down is a parabola. If the height is too high, it will cause the clothes to hit the clothes processing barrel during parabolic motion. The highest point of the clothes parabolic motion is lower than the radius of the clothes processing barrel, which is lower than the height of the clothes parabolic motion higher than the radius of the clothes processing barrel, so the motion distance of the clothes when falling down will be shorter, so the clothes cannot fully unfold. If the clothes with large mass are dried, 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.

[0132] When the maximum value Hmax of the clothes height exceeds the radius Hr of the clothes treatment barrel, the control mainboard will further analyze the change of the clothes area. By calculating the difference ΔS=Smax-Smin between the maximum value Smax and the minimum value Smin of the clothes area in a group of pictures, it can be evaluated whether the clothes are close to the barrel wall of the clothes treatment barrel, wherein the pictures within one rotation of the clothes treatment barrel are a group. If ΔS is less than a set threshold value ΔS1, it means that the clothes may be close to the barrel wall of the clothes treatment barrel, at which time the control mainboard will reduce the motor speed to v2 to promote the unfolding of the clothes. As the drying process advances, the clothes humidity gradually decreases, and the value of ΔS will also change accordingly. Therefore, throughout the drying process, the control mainboard will continuously monitor the clothes unfolding state until the drying is completed.

[0133] In order to further optimize the drying effect, the control mainboard adopts a method of dynamically adjusting the motor speed. Specifically, each time the detected clothes difference ΔSi is compared with the previous difference ΔSi-1. If ΔSi-1 is less than ΔSi, it means that the clothes unfolding degree has improved, at which time the control mainboard will appropriately increase the motor speed to v3, wherein v3 equals (v3=v2-Δv), to maintain a good unfolding state; otherwise, if ΔSi-1 is greater than ΔSi, it indicates that the clothes may be too unfolded, and the control mainboard will reduce the motor speed to avoid damage to the clothes caused by excessive unfolding. Through this dynamic adjustment strategy, the control mainboard can continuously optimize the unfolding state of the clothes throughout the drying process, thereby achieving the best drying effect.

[0134] Finally, when the clothes treatment device completes the drying and determines that the clothes are dry, the entire control process is completed.

[0135] In this preferred embodiment, ΔT1 is the time interval at which the camera takes pictures, which is a time interval that can clearly capture the movement trajectory of the clothes within one rotation, making the image recognition more accurate. v1 is the starting drying speed in the normal washing machine program logic, v2 is the speed that is beneficial to the unfolding of the clothes, and at the same time, it is used to judge whether the clothes are unfolded at this rotation. Δv is a step value used to adjust the clothes unfolding state, which needs to be obtained through specific experiments according to different models. ΔS1 is a value representing the state of the clothes being close to the barrel, which is used to judge whether the clothes are close to the barrel.

[0136] In summary, the ingenious idea of the clothes drying control method lies in:

[0137] By acquiring image information of the clothes during rotation of the clothes treatment barrel for at least one round, 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 of the clothes related to the rotating speed of the clothes treatment barrel, more accurate data support can be provided for clothes drying, the rotating speed of the clothes treatment barrel can be adjusted according to different unfolding states of the clothes, the clothes can be kept in a fully unfolded state in the clothes treatment barrel, the clothes can be better contacted with hot air in the clothes treatment barrel, and the clothes can be better dried, so that the drying efficiency of the clothes is improved, and the drying time and energy consumption are reduced.
