[0072] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0073] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0074] According to an embodiment of the present application, an embodiment of a method for controlling the washing rhythm of a laundry appliance is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0075] like Figure 1 As shown, the method includes the following steps:

[0076] Step S101 : obtaining a plurality of first clothing images of clothing in a drum at a first washing rhythm.

[0077] Among them, the washing rhythm includes the drum speed and the start-stop ratio.

[0078] Specifically, under the first washing rhythm, multiple first clothing images are acquired from the laundry inside the drum. A sampling period and a sampling frequency can be set to acquire the first clothing images. For example, R first clothing images are acquired per second. Alternatively, S first clothing images can be acquired per one rotation of the drum. Acquiring the first clothing images prepares for subsequently determining the first clothing trajectory based on the first clothing images.

[0079] Step S102: determining a first clothing trajectory according to the plurality of first clothing images.

[0080] The clothing trajectory refers to the trajectory of the clothing moving in the drum.

[0081] Specifically, the position information of the clothing is determined based on the multiple first clothing images, and then the first clothing trajectory of the clothing is obtained based on the multiple position information. The determination of the first clothing trajectory prepares for the subsequent judgment of the abnormal state of the clothing.

[0082] Step S103: determining whether the clothing is in an abnormal state according to the first clothing trajectory.

[0083] The abnormal state includes that at least part of the clothes cannot be lifted and / or at least part of the clothes stick to the wall. The abnormal state of the clothes will directly affect the washing effect of the clothes.

[0084] Specifically, based on the first clothing trajectory, the movement state of the clothes in the drum can be clearly determined, and then based on the movement state of the clothes and the abnormal state, it can be judged whether there is any abnormality in the movement state of the clothes. If the clothes are in an abnormal state, the washing effect of the clothes will be affected. Therefore, if there are clothes in an abnormal state, the drum speed can be adjusted to make the clothes reach a normal state, thereby improving the washing effect of the clothes. The judgment of the abnormal state of the clothes in this step prepares for whether the speed needs to be adjusted later.

[0085] Step S104: When it is determined that the clothes are in an abnormal state, the first washing rhythm is adjusted to make the clothes reach a normal state.

[0086] The normal state is when all clothes are lifted up and not attached to the wall.

[0087] In this step, after obtaining the first clothing trajectory based on the multiple first clothing images obtained, it is determined that the clothing is in an abnormal state based on the first clothing trajectory. The state of the clothing can be adjusted by adjusting the first washing rhythm to make the clothing reach a normal state, thereby achieving the best washing effect of the clothing.

[0088] When adjusting the washing rhythm, the control of the drum speed of the laundry equipment may refer to the control of the motor. The motor and the rotating shaft of the drum are coaxial, and the drum speed can be controlled by controlling the speed of the motor.

[0089] In an embodiment of the present application, multiple first images of clothing in the drum are acquired under a first washing rhythm, wherein the washing rhythm includes the drum speed and the rotation-stop ratio; a first clothing trajectory is determined based on the multiple first clothing images; and it is determined based on the first clothing trajectory whether the clothing is in an abnormal state, wherein the abnormal state includes at least part of the clothing being unable to be lifted and / or at least part of the clothing sticking to the wall; if it is determined that the clothing is in an abnormal state, the first washing rhythm is adjusted to bring the clothing to a normal state. In this way, the method of the present application realizes acquiring the first clothing image of the clothing during the rotation of the drum, thereby obtaining the first clothing trajectory, determining whether the state of the clothing is abnormal based on the first clothing trajectory, and then adjusting the first washing rhythm when it is determined that the clothing is in an abnormal state. In this way, the drum rotation speed, rotation-stop ratio, etc. can be adjusted according to the state of the clothing, so that the state of the clothing can always be in a normal state, thereby achieving a better washing effect.

[0090] In another embodiment of the present application, step S104: when it is determined that the clothes are in an abnormal state, adjusting the first washing rhythm, including: when the abnormal state is that at least part of the clothes cannot be lifted, or the abnormal state is that part of the clothes cannot be lifted and part of the clothes are stuck to the wall, adjusting the first washing rhythm through the first control logic; when the abnormal state is that at least part of the clothes are stuck to the wall, adjusting the first washing rhythm through the second control logic.

[0091] Among them, the first control logic and the second control logic are used to adjust the washing rhythm.

[0092] Specifically, if the abnormal state is that at least part of the clothes cannot be lifted, or if the abnormal state is that part of the clothes cannot be lifted and part of the clothes stick to the wall, the first washing rhythm can be adjusted through the first control logic. If the abnormal state is that at least part of the clothes stick to the wall, the first washing rhythm can be adjusted through the second control logic. In the embodiment of the present application, different control logics are set to adjust the washing rhythm according to different abnormal states, so that the washing of clothes is more accurate, thereby improving the washing effect of clothes.

[0093] In another embodiment of the present application, the first washing rhythm is adjusted through the first control logic, including: increasing the first start-stop ratio in the first washing rhythm to a preset start-stop ratio; increasing the drum speed, and in the process of increasing the drum speed, obtaining multiple second clothing images of the clothes in the drum; when the second clothing trajectory is obtained based on the multiple second clothing images and it is judged that all the clothes are lifted, the second speed at this time is determined, and the acceleration of the second speed is reduced to zero; collecting multiple real-time speeds, and when the fluctuation value of the real-time speed reaches the preset fluctuation requirement, multiple third clothing images of the clothes in the drum are obtained; according to the multiple third clothing images, the third clothing trajectory is obtained to determine whether all the clothes are attached to the wall; when not all the clothes are attached to the wall, the real-time speed when the fluctuation value reaches the preset fluctuation requirement is determined as the target second speed; when all the clothes are attached to the wall, the current real-time speed is increased to the second speed, and the second speed is used as the target second speed; the second washing rhythm is obtained based on the target second speed and the preset start-stop ratio; and the first washing rhythm is adjusted to the second washing rhythm.

[0094] The preset fluctuation requirement may refer to a fluctuation value being within a preset fluctuation range, or a fluctuation value being less than a preset fluctuation threshold, etc.

[0095] Specifically, the start-stop ratio of the first wash rhythm is increased to a preset start-stop ratio, thereby improving the washing effect of the clothes by increasing the wash time and changing the drum speed. The present application also increases the drum speed, and during this process, continuously acquires multiple second images of the clothes in the drum. A second clothing trajectory is obtained based on the multiple second images. When it is determined based on the second images that all the clothes have been lifted, the second speed at that time is recorded. At this point, the clothes have been lifted, thus resolving the problem of at least some clothes being unable to be lifted. The acceleration of the second speed is reduced to zero, and multiple real-time speeds are acquired. When the fluctuation value of the real-time speed reaches a preset fluctuation requirement, multiple third images of the clothes in the drum are acquired at that time. Due to the presence of clothes in the drum, the drum speed fluctuates continuously during rotation due to the influence of the clothes in the drum. When the acceleration of the second speed is reduced to zero, the drum speed fluctuates significantly due to the acceleration from acceleration to stop. By continuously acquiring multiple real-time speeds, when the fluctuation value of the real-time speed reaches the preset fluctuation requirement, it indicates that the drum speed is becoming stable. The third images of clothes acquired at this time can more accurately reflect the state of the clothes in the drum. Then, a third clothing trajectory is obtained, and based on the third clothing trajectory, it is determined whether all the clothes are stuck to the wall. If all the clothes are stuck to the wall, the current real-time rotation speed is adjusted to the second rotation speed, and the second rotation speed is used as the target second rotation speed. In this way, it is ensured that at the second rotation speed, the clothes are lifted up from a state where at least part of the clothes cannot be lifted to a state where all the clothes cannot be lifted, so that the clothes can avoid being unable to be lifted. If not all the clothes are stuck to the wall, the real-time rotation speed when the fluctuation value reaches the preset fluctuation requirement is determined to be the target second rotation speed. Based on the target second rotation speed and the preset start-stop ratio, the second washing rhythm is obtained, and then the first washing rhythm is adjusted to the second washing rhythm. In this way, the present application realizes the adjustment of the first washing rhythm through the first control logic, and for the determination of the target second rotation speed in the second washing rhythm, the fluctuation of the real-time rotation speed, the excessive increase in rotation speed causing all the clothes to stick to the wall, etc. are taken into account, so that the determination of the target second rotation speed is more accurate, thereby achieving a better washing effect.

[0096] In another embodiment of the present application, after obtaining the second washing rhythm, the method further includes: at the target second speed, determining whether some clothes are stuck to the wall; if all clothes are not stuck to the wall, washing the clothes using the second washing rhythm.

[0097] In the present application, at the target second speed, all the clothes are lifted. A method for determining whether any of the clothes are stuck to the wall can be to obtain multiple images of the clothes at the target second speed, obtain clothing trajectories based on the multiple images, and then determine whether the clothes are stuck to the wall based on the clothing trajectories. If none of the clothes are stuck to the wall, the second washing rhythm is used to wash the clothes. In this way, when washing clothes, the laundry machine not only ensures that all the clothes are lifted, but also ensures that none of the clothes are stuck to the wall, and the clothes are in a normal state, thereby achieving the best washing effect.

[0098] In another embodiment of the present application, after determining whether some clothes are stuck to the wall at the target second speed, the method further includes: if some clothes are stuck to the wall, adjusting the second washing rhythm through the second control logic.

[0099] In this application, if it is determined that some clothing is sticking to the wall at the target second speed, the second control logic can be used to adjust the second wash rhythm to improve the cleaning efficiency of the clothing. The method for adjusting the second wash rhythm by the second control logic is the same as the method for adjusting the first wash rhythm by the second control logic, which will be explained in detail in the following embodiments and will not be repeated here.

[0100] In another embodiment of the present application, the first washing rhythm is adjusted by the second control logic, including: increasing the first start-stop ratio in the first washing rhythm to a preset start-stop ratio; reducing the current drum speed, and in the process of reducing the drum speed, obtaining multiple fourth clothing images of the clothes in the drum; when the fourth clothing trajectory is obtained based on the multiple fourth clothing images and it is judged that the clothes are not all attached to the wall, the third speed at this time is determined, and the acceleration of the third speed is reduced to zero; collecting multiple real-time speeds, and when the fluctuation value of the real-time speed reaches the preset fluctuation requirement, multiple fifth clothing images of the clothes in the drum are obtained; the fifth clothing trajectory is obtained based on the multiple fifth clothing images to determine whether all the clothes cannot be lifted; when not all the clothes cannot be lifted, the real-time speed when the fluctuation value reaches the preset fluctuation requirement is determined as the target third speed; when all the clothes cannot be lifted, the current real-time speed is adjusted to the third speed, and the third speed is used as the target third speed; the third washing rhythm is obtained based on the target third speed and the preset start-stop ratio; and the first washing rhythm is adjusted to the third washing rhythm.

[0101] Among them, the preset fluctuation requirement has the same meaning as the preset fluctuation requirement in the aforementioned embodiment. The preset fluctuation range or preset fluctuation threshold in this application and the aforementioned embodiment can be the same, and of course, can also be different.

[0102] Specifically, the first rotation-stop ratio in the first wash rhythm is increased to a preset rotation-stop ratio, thereby improving the washing effect of the clothes by increasing the wash time and changing the drum speed. The drum speed is then reduced, and during this process, multiple fourth pieces of clothing are captured within the drum, thereby obtaining fourth clothing trajectories. Based on the fourth clothing trajectories, if it is determined that none of the clothing is sticking to the wall, the problem of at least some of the clothing sticking to the wall has been resolved, and the third speed at that time is recorded. The acceleration of the third speed is then reduced to zero, and multiple real-time speeds are captured in real time. When the fluctuation value of the real-time speed meets a preset fluctuation requirement, multiple fifth clothing images within the drum are captured. Due to the presence of clothing within the drum, the drum speed fluctuates continuously during rotation due to the influence of the clothing within the drum. When the acceleration of the third speed is reduced to zero, the drum speed fluctuates significantly from deceleration to cessation. By continuously capturing multiple real-time speeds, when the fluctuation value of the real-time speed meets the preset fluctuation requirement, it indicates that the drum speed has stabilized. The fifth clothing images captured at this time more accurately reflect the state of the clothing within the drum. A fifth clothing trajectory is obtained based on multiple fifth clothing images, and then it is determined based on the fifth clothing trajectory whether all the clothes cannot be lifted. If not all the clothes cannot be lifted, the real-time speed when the fluctuation value reaches the preset fluctuation requirement is used as the target third speed. If all the clothes cannot be lifted, the current real-time speed is adjusted to the third speed, and the third speed is determined as the target third speed. Based on the target third speed and the preset start-stop ratio, the third washing rhythm is obtained, and the first washing rhythm is adjusted to the third washing rhythm. In this way, the first washing rhythm is adjusted to the third washing rhythm through the second control logic, so that the washing effect of the clothes is better.

[0103] In another embodiment of the present application, after obtaining the third washing rhythm, the method further includes: at the target third speed, determining whether some clothes cannot be lifted; if all clothes are lifted, washing the clothes using the third washing rhythm.

[0104] In an embodiment of the present application, at the target third speed, multiple clothing images are obtained, and clothing trajectories are obtained based on the multiple clothing images. Then, based on the clothing trajectories, it is determined whether there is a situation where some clothes cannot be lifted. If all clothes are lifted, then at the third washing rhythm, all clothes are lifted and none of them stick to the wall, and the state of the clothes reaches the best. The third washing rhythm is used to wash clothes, which improves the washing ratio of the clothes and makes the washing effect of the clothes better.

[0105] In another embodiment of the present application, after obtaining the third washing rhythm, at the target third speed, it is determined whether some clothes cannot be lifted. If some clothes cannot be lifted, the second washing rhythm and the third washing rhythm are controlled to alternately control the rotation of the drum.

[0106] In an embodiment of the present application, when it is determined that part of the clothes cannot be lifted, it means that at the third speed, the clothes cannot be lifted, and the second washing rhythm and the third washing rhythm are alternately performed. In the second washing rhythm, it is ensured that all the clothes are lifted, and in the third washing rhythm, it is ensured that the clothes are not stuck to the wall. In this way, in the alternating washing rhythms, the clothes can avoid the situation where part of the clothes continues to stick to the wall or continues to be unable to be lifted. Under the alternating control of the second washing rhythm and the third washing rhythm, the state of the clothes changes continuously, thereby improving the washing effect of the clothes.

[0107] In another embodiment of the present application, the first control logic and the second control logic can be implemented through a BP neural network (Back-Propagation Neural Network).

[0108] In another embodiment of the present application, the second wash rhythm is adjusted using a second control logic, using the same logic as the previously described method for adjusting the first wash rhythm using the second control logic. However, when the drum speed is reduced, the speed is reduced based on the target second speed. If a target third speed is achieved, and the trajectory of the laundry is determined at the target third speed to indicate that a portion of the laundry cannot be lifted, the second and third wash rhythms are alternatingly controlled, thereby achieving a thorough washing of the laundry and improving the laundry washing effect.

[0109] In another embodiment of the present application, determining the first clothing trajectory based on multiple first clothing images includes: identifying the position information of the clothing by performing image recognition on each first clothing image; and obtaining the first clothing trajectory based on the position information of each clothing and the order in which the first clothing images are obtained.

[0110] Among them, the image recognition method can refer to a convolutional neural network model, color feature-based recognition, texture feature-based recognition, etc.

[0111] In the embodiment of the present application, the position information of the clothing is obtained by image recognition of each first clothing image, and then the first clothing trajectory is obtained based on the order in which the position information of each clothing item and the first clothing image corresponding to the clothing position information are obtained. The embodiment of the present application realizes the determination of the first clothing trajectory. Similarly, in the aforementioned embodiment, the method for obtaining the second clothing trajectory, the third clothing trajectory, the fourth clothing trajectory, and the fifth clothing trajectory can be the same. The position information of the clothing obtained through image recognition is more accurate, thereby making the clothing trajectory more accurate.

[0112] In another embodiment of the present application, multiple images of first clothes in the drum are captured by at least one camera provided in the laundry device, wherein the camera's shooting range covers the drum. The camera can also capture images of second clothes.

[0113] Specifically, when the laundry machine is washing clothes, at least one camera provided in the laundry machine captures multiple images of the clothes in the drum at different times as the drum rotates one revolution. The camera provided in the laundry machine in this application captures the clothes images conveniently, quickly, and in real time. In this application, there can be one camera, and the camera's range covers the drum. There can be multiple cameras, and the combined range of each camera covers the drum. The location of the camera can be set according to actual circumstances and is not limited in this embodiment of the application.

[0114] In another embodiment of the present application, before obtaining multiple first clothing images of the clothing in the drum under the first washing rhythm, the method also includes: obtaining the weight of the clothing in the drum; controlling the rotation of the drum according to a preset speed, and obtaining the number of times the clothing is beaten within a preset time period; obtaining the first washing rhythm according to the weight of the clothing in the drum, the number of times the clothing is beaten within a preset time period, and the preset speed; according to the first washing rhythm and the mapping relationship, determining the first speed and the first start-stop ratio corresponding to the first washing rhythm from the mapping relationship; the mapping relationship includes the relationship between the washing rhythm and the speed and the start-stop ratio in the washing rhythm.

[0115] Among them, the preset speed refers to the initial speed in the washing state, which can be set according to the actual situation. The purpose of the preset speed is to rotate the drum, and then obtain the number of times the clothes are thrown within the preset time. The preset time can be set according to the actual situation, for example, 2 minutes, etc. The number of times the clothes are thrown can be determined based on the clothes image, and the movement trajectory of the clothes can be obtained to determine whether the clothes are thrown. That is, when obtaining the clothes image of the clothes, multiple clothes images can be obtained every time the drum rotates one circle, and the movement trajectory of the clothes can be obtained every time the drum rotates one circle to determine whether the clothes are thrown.

[0134] Based on the target second rotation speed and the preset rotation-stop ratio, a second washing rhythm is obtained.

[0135] Step S313: At the current drum speed, determine whether some clothes are stuck to the wall. If all clothes are not stuck to the wall, execute step S314; if some clothes are stuck to the wall, execute step S315.
