Description

Technical Field

[0001] This application relates to the field of equipment control. Specifically, it relates to a dehydration control method, an electronic device, and a fabric processing device for a fabric processing device. Background Art

[0002] A fabric processing device refers to a device that processes fabrics such as washing, dehydrating, drying, and caring for fabrics. Taking a drum washing machine as an example, before dehydrating the fabric, the current drum washing machine will level the fabric according to preset leveling parameters to reduce the eccentricity value of the fabric. However, this control method is prone to long-term leveling, reducing the dehydration efficiency. Summary of the Invention

[0003] Embodiments of this application provide a dehydration control method, an electronic device, and a fabric processing device for a fabric processing device to at least solve the technical problem of reducing dehydration efficiency.

[0004] According to the first aspect of the embodiments of this application, a dehydration control method for a fabric processing device is provided. The method includes:

[0005] Obtain the eccentricity value and weight value of the fabric in the processing cylinder;

[0006] Determine a centrifugal force characteristic value according to the eccentricity value and weight value, where the centrifugal force characteristic value characterizes the centrifugal force situation of the fabric when the processing cylinder rotates;

[0007] Determine a reference target speed according to the eccentricity value, weight value, and centrifugal force characteristic value;

[0008] Control the rotation of the processing cylinder according to the reference target speed.

[0009] By adopting this embodiment, by obtaining the eccentricity value and weight value of the fabric, the reference target speed calculated according to the eccentricity value, weight value, and centrifugal force characteristic value fits the actual situation of the fabric. Then, by controlling the rotation of the processing cylinder according to the reference target speed, it is easier to control the speed of the processing cylinder within the range that can efficiently reduce the eccentricity of the fabric, so that the eccentricity reduction rate of the fabric is increased, thereby improving the dehydration efficiency.

[0010] Combined with the first aspect, in an alternative implementation manner of the embodiments of this application, the determining the centrifugal force characteristic value according to the eccentricity value and weight value includes:

[0011] Determine the centrifugal force characteristic value according to the product of the eccentricity value and weight value.

[0012] By adopting this embodiment, the calculation process of the centrifugal force characteristic value is simple, which is easy to save computing resources, reduce computing costs, and improve dehydration efficiency.

[0013] In a possible implementation manner of the embodiment of the present application in combination with the first aspect, the determining the reference target rotation speed according to the eccentricity value, weight value, and centrifugal force characteristic value includes:

[0014] After weighting the eccentricity value, weight value, and centrifugal force characteristic value, calculate the operation result between a preset compensation term and the weighted eccentricity value, weight value, and centrifugal force characteristic value to obtain an initial target rotation speed;

[0015] Calculate the reference target rotation speed and the rotation speed maintenance duration according to the initial target rotation speed, where the rotation speed maintenance duration includes the time that the actual rotation speed of the processing cylinder maintains when reaching the reference target rotation speed.

[0016] Adopting this implementation manner, first calculate the initial target rotation speed using the calculation model, and then calculate the reference target rotation speed and the rotation speed maintenance duration for controlling the rotation of the processing cylinder using the initial target rotation speed, which is beneficial for the calculated reference target rotation speed to fit the actual situation of the fabric. Then, control the rotation of the processing cylinder according to the reference target rotation speed, and it is easier to control the rotation speed of the processing cylinder within the range that can efficiently reduce the eccentricity of the fabric, so that the eccentricity reduction rate of the fabric is increased, thereby improving the dehydration efficiency.

[0017] In a possible implementation manner of the embodiment of the present application in combination with the first aspect, the compensation term includes an intercept term and an error term;

[0018] After weighting the eccentricity value, weight value, and centrifugal force characteristic value, calculating the operation result between a preset compensation term and the weighted eccentricity value, weight value, and centrifugal force characteristic value to obtain an initial target rotation speed includes:

[0019] y = β0 + β1·x1 + β2·x2 + β3·x1·x2 + ∈;

[0020] where y is the initial target rotation speed, x1 is the eccentricity value, x2 is the weight value, β0 is the intercept term, β1 is the main effect weight of the eccentricity value, β2 is the main effect weight of the weight value, β3 is the interaction term weight of the eccentricity value and the weight value, and ∈ is the error term;

[0021] where β0, β1, β2, β3, and ∈ are all constant terms.

[0022] Adopting this implementation manner, the calculation process is simple, which is easy to save computing resources, reduce the computing cost, and improve the computing efficiency.

[0023] In a possible implementation manner of the embodiment of the present application in combination with the first aspect, the calculating the reference target rotation speed and the rotation speed maintenance duration according to the initial target rotation speed includes:

[0024] Calculate the preset correction parameter and the initial target speed to obtain the reference target speed;

[0025] Determine the speed maintenance duration from a preset mapping relationship according to the initial target speed or the reference target speed, where the mapping relationship includes the corresponding relationship between the initial target speed and the speed maintenance duration or the corresponding relationship between the reference target speed and the speed maintenance duration;

[0026] Among them, the larger the initial target speed, the larger the reference target speed.

[0027] Adopting this implementation method is beneficial to further improve the fitting degree between the reference target speed and the actual situation of the fabric, thereby reducing the eccentricity during the rotation of the processing cylinder, and improving the dehydration efficiency.

[0028] Combined with the first aspect, in an alternative implementation of the embodiment of the present application, after determining the reference target speed according to the eccentricity value, weight value and centrifugal force characteristic value, the method further includes:

[0029] If the reference target speed is less than the preset dehydration required speed, control the processing cylinder to rotate within a preset speed range, and re-obtain the eccentricity value and weight value, so as to calculate a new reference target speed according to the re-obtained eccentricity value and weight value, until the new reference target speed is not less than the dehydration required speed or the new reference target speed is not greater than 0. Among them, when the new reference target speed is not less than the dehydration required speed, control the processing cylinder to rotate according to the new reference target speed, and when the new reference target speed is not greater than 0, end the dehydration.

[0030] Adopting this implementation method, when the reference target speed is less than the dehydration required speed, it proves that when controlling the processing cylinder to rotate according to the reference target speed, the speed of the processing cylinder cannot reach the dehydration required speed. At this time, re-obtain the eccentricity value and weight value. Since the processing cylinder will rotate when re-obtaining the eccentricity value and weight value, the eccentricity of the fabric can be reduced slightly, so that the new reference target speed calculated according to the re-obtained eccentricity value and weight value is different from the previous one, so as to realize that by re-obtaining the eccentricity value and weight value again and again, the reference target speed is not less than the dehydration required speed, so as to ensure that the speed of the processing cylinder during dehydration can reach the dehydration required speed and improve the dehydration effect.

[0031] Combined with the first aspect, in an alternative implementation of the embodiment of the present application, the method further includes:

[0032] Obtain the actual maximum speed of the processing cylinder during the process of controlling the processing cylinder to rotate according to the reference target speed;

[0033] If the actual maximum rotation speed is less than the reference target rotation speed, control the processing cylinder to decelerate, and re-acquire the eccentricity value and the weight value, so as to calculate the reference target rotation speed according to the re-acquired eccentricity value and weight value, and control the processing cylinder to rotate according to the newly calculated reference target rotation speed, so as to obtain the new actual maximum rotation speed, until the new actual maximum rotation speed is not less than the newly calculated reference target rotation speed, and control the rotation speed of the processing cylinder to increase to the dehydration required rotation speed.

[0034] With this implementation method, the fact that the actual maximum rotation speed is less than the reference target rotation speed proves that the rotation speed of the processing cylinder is relatively small during the actual rotation process. At this time, the eccentricity value and the weight value are re-acquired. Since the processing cylinder will be controlled to rotate when the eccentricity value and the weight value are re-acquired, the eccentricity degree of the fabric can be reduced slightly, so that the new reference target rotation speed calculated according to the re-acquired eccentricity value and weight value is different from the previous one. Thus, by re-acquiring the eccentricity value and the weight value time by time, the reference target rotation speed is not less than the dehydration required rotation speed, so as to ensure that the rotation speed of the processing cylinder can reach the dehydration required rotation speed during dehydration and improve the dehydration effect.

[0035] Combined with the first aspect, in an alternative implementation manner of the embodiment of the present application, before re-acquiring the eccentricity value and the weight value, the method further includes:

[0036] If the number of times of re-acquiring the eccentricity value and the weight value reaches a preset number threshold, reduce the reference target rotation speed calculated in the previous time, control the processing cylinder to rotate according to the reduced reference target rotation speed, and then execute the re-acquisition of the eccentricity value and the weight value again.

[0037] With this implementation method, if the rotation speed of the processing cylinder still cannot be increased to a large extent after re-acquiring the eccentricity value and the weight value multiple times, directly reduce the reference target rotation speed, so that the processing cylinder can realize the most basic rotation, so that the eccentricity of the fabric changes during the rotation of the processing cylinder, and then re-acquire the eccentricity value and the weight value, which is beneficial to increasing the rotation speed of the processing cylinder to the dehydration required rotation speed. Since the intervention method of directly reducing the reference target rotation speed is adopted, it is beneficial to quickly complete the adjustment of the eccentricity of the fabric, thereby improving the dehydration efficiency.

[0038] Combined with the first aspect, in an alternative implementation manner of the embodiment of the present application, the obtaining of the eccentricity value and the weight value of the fabric in the processing cylinder includes:

[0039] Control the processing cylinder to accelerate;

[0040] When the rotation speed of the processing cylinder reaches a preset measurement rotation speed, obtain the eccentricity value and the weight value, where the measurement rotation speed is within a preset rotation speed range.

[0041] With this implementation method, when obtaining the eccentricity value and the weight value, the processing cylinder is controlled to increase its speed to the measurement speed, which is beneficial to ensuring the accuracy of the eccentricity value and the weight value, thereby ensuring the fit between the reference target speed and the fabric, accelerating the process of adjusting the fabric eccentricity, and improving the dehydration efficiency.

[0042] Combined with the first aspect, in an alternative implementation manner of the embodiment of the present application, the water absorption values of the fabric are different, and the corresponding measurement speeds are different, wherein the water absorption value is determined according to the volume and the water absorption amount of the fabric.

[0043] With this implementation method, fabrics with different water absorption values use different measurement speeds, which is beneficial to improving the accuracy of the eccentricity value and the weight value, thereby ensuring the fit between the reference target speed and the fabric, accelerating the process of adjusting the fabric eccentricity, and improving the dehydration efficiency.

[0044] Combined with the first aspect, in an alternative implementation manner of the embodiment of the present application, before obtaining the eccentricity value and the weight value of the fabric in the processing cylinder, the method further includes:

[0045] Judging whether the load type of the fabric is a preset target type that is easy to absorb water;

[0046] If so, execute obtaining the eccentricity value and the weight value of the fabric in the processing cylinder.

[0047] With this implementation method, obtaining the eccentricity value and the weight value for the fabric of the target type that is easy to absorb water is conducive to quickly leveling the fabric that is easy to absorb water and improving the dehydration efficiency.

[0048] Combined with the first aspect, in an alternative implementation manner of the embodiment of the present application, the judging whether the load type of the fabric is a preset target type that is easy to absorb water includes:

[0049] Calculating the difference between the weight of the fabric after water absorption and the weight before water absorption, and dividing the difference by the volume of the fabric to obtain the water absorption value;

[0050] If the water absorption value exceeds a preset water absorption threshold, it is judged that the load type of the fabric is the target type.

[0051] With this implementation method, the difference between the weight of the fabric after water absorption and the weight before water absorption can reflect the water absorption weight of the fabric, and then dividing the difference by the volume of the fabric to obtain the water absorption value can reflect whether the fabric belongs to the load type that is easy to absorb water.

[0052] According to the second aspect of the embodiment of the present application, there is provided an electronic device, and the electronic device includes a memory and a processor;

[0053] The memory is used for storing a computer program;

[0054] The processor is configured to execute the computer program to implement the steps of the method described above.

[0055] According to a third aspect of the embodiments of the present application, a fabric processing device is provided, which includes the electronic device described above.

[0056] The technical effects obtained in the second and third aspects are similar to those obtained by the corresponding technical means in the first aspect, and will not be elaborated here. Description of the Drawings

[0060] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0061] It should be understood that the "plurality" mentioned herein refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means "or", for example, A / B may mean A or B; the "and / or" herein is only a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B may mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in order to clearly describe the technical solutions in the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the terms "first" and "second" do not limit the quantity and execution order, and the terms "first" and "second" do not necessarily mean different.

[0062] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to those processes, methods, products, or devices.

[0063] When a drum washing machine dewatering, it is necessary to evenly distribute the clothes and then control it to increase the speed for dewatering. The purpose of doing this is to reduce the phenomenon that the washing machine shifts or vibrates greatly during high-speed dewatering. The general control scheme is to find the rotation speed and acceleration that are easier to evenly distribute the load through a large number of data experiments, set fixed eccentricity and weighing parameters and the number of attempts. After repeated attempts, when it is detected that the clothes are evenly distributed, that is, when the eccentricity value is less than the preset eccentricity limit value, the speed can be increased.

[0064] In the above scheme, when dealing with untested types of clothes, there is a situation where the clothes are repeatedly tried to be distributed and cannot reach a state below the normal dewatering eccentricity limit value. The number of attempts is relatively large, resulting in phenomena such as dewatering delay or the clothes not being dried.

[0065] In view of this phenomenon, this scheme is specifically proposed to solve the control scheme for the clothes distribution to adapt to diverse loads, improve the efficiency of the clothes distribution process, reduce the distribution time, reduce the eccentricity value after distribution, so that the dewatering speed can be further increased, and reduce the phenomena of delay and not being dried.

[0066] Based on this, the embodiments of the present application provide a dewatering control method, an electronic device and a fabric treatment device for a fabric treatment device, which at least solve the following problems:

[0067] 1. When a drum washing machine distributes clothes, there is a repeated distribution process, and the effective distribution process is less, which will affect the low dewatering speed of the clothes or the clothes not being dried.

[0068] It at least has the following characteristics:

[0069] 1. Obtain the eccentricity and weighing of the clothes, input the eccentricity and weighing into the parameter calculation module, and output the corresponding target dewatering speed.

[0070] Next, the dewatering control method of the fabric treatment device provided by the embodiments of the present application will be further described. Refer to Figure 1 As shown in the flowchart of the dewatering control method of the fabric treatment device, the method includes the following processing procedures.

[0071] S100. Obtain the eccentricity value and weight value of the fabric in the processing cylinder.

[0072] In one embodiment, the fabric processing device includes a processing cylinder for containing the fabric to be processed. When dehydrating the fabric, the fabric is inside the processing cylinder, and the eccentricity value and weight value of the fabric are obtained using existing algorithms or sensors. It should be noted that when measuring the eccentricity value and weight value, the eccentricity value and weight value can be calculated or converted by detecting relevant parameters of the processing cylinder. That is to say, when measuring the eccentricity value and weight value in this embodiment, the processing cylinder and the fabric can be measured as a whole.

[0073] It should be noted that at least when measuring the eccentricity value, it is necessary to control the rotation of the processing cylinder, and during the rotation of the processing cylinder, the eccentricity value is obtained. During the rotation of the processing cylinder, the water content of the fabric and the stacking state between the fabrics will change, resulting in a change in the eccentricity value. When determining the eccentricity value, the stabilized eccentricity value can be used as the measurement result of each eccentricity value.

[0074] S102. Determine the centrifugal force characteristic value according to the eccentricity value and the weight value.

[0075] Among them, the centrifugal force characteristic value characterizes the centrifugal force situation of the fabric when the processing cylinder rotates.

[0076] S104. Determine the reference target rotation speed according to the eccentricity value, the weight value and the centrifugal force characteristic value.

[0077] In one embodiment, the eccentricity value, the weight value and the centrifugal force characteristic value all affect the rotation speed of the processing cylinder. Specifically, the larger the eccentricity value, the smaller the maximum rotation speed that the processing cylinder can reach, and the larger the weight value, the smaller the maximum rotation speed that the processing cylinder can reach. Therefore, based on the relationship between the eccentricity value and the weight value and the rotation speed of the processing cylinder, a relational expression can be fitted. When the eccentricity value and the weight value are obtained, the reference target rotation speed can be calculated according to the relational expression.

[0078] S106. Control the rotation of the processing cylinder according to the reference target rotation speed.

[0079] In one embodiment, since the state and eccentricity of the fabric are prone to change during the rotation of the processing cylinder, when controlling the rotation of the processing cylinder according to the reference target rotation speed, the torque of the motor used to drive the rotation of the processing cylinder is controlled so that the processing cylinder can theoretically reach the reference target rotation speed under this torque.

[0080] Since the reference target rotation speed is calculated according to the actual eccentricity value and weight value of the fabric, controlling the rotation of the processing cylinder according to the reference target rotation speed is conducive to efficiently reducing the eccentricity value of the fabric, enabling the processing cylinder to rotate at a higher speed and realizing dehydration of the fabric.

[0081] By adopting this embodiment, by obtaining the eccentricity value and weight value of the fabric, the reference target rotation speed calculated according to the eccentricity value, weight value and centrifugal force characteristic value fits the actual situation of the fabric. Then, the processing cylinder is controlled to rotate according to the reference target rotation speed, which is more likely to control the rotation speed of the processing cylinder within the range that can efficiently reduce the eccentricity of the fabric, so that the eccentricity reduction rate of the fabric is increased, thereby improving the dehydration efficiency.

[0082] Optionally, in an implementation manner of this embodiment, determining the centrifugal force characteristic value according to the eccentricity value and weight value includes:

[0083] Determining the centrifugal force characteristic value according to the product of the eccentricity value and the weight value.

[0084] By adopting this embodiment, the calculation process of the centrifugal force characteristic value is simple, which is easy to save computing resources, reduce the computing cost, and improve the dehydration efficiency.

[0085] Optionally, in an implementation manner of this embodiment, determining the reference target rotation speed according to the eccentricity value, weight value and centrifugal force characteristic value includes:

[0086] After weighting the eccentricity value, weight value and centrifugal force characteristic value, calculating the operation result between the preset compensation term and the weighted eccentricity value, weight value and centrifugal force characteristic value to obtain the initial target rotation speed;

[0087] Calculating the reference target rotation speed and the rotation speed maintenance duration according to the initial target rotation speed, where the rotation speed maintenance duration includes the time that the actual rotation speed of the processing cylinder maintains when it reaches the reference target rotation speed.

[0088] In one embodiment, the initial target rotation speed is calculated according to the relationship among the eccentricity value, weight value and centrifugal force characteristic value. In order to improve the adjustment effect of the fabric eccentricity, the initial target rotation speed is calculated again. During this calculation process, that is, during the process of calculating the reference target rotation speed, other considerations can be incorporated, such as different fabrics of different materials can reach different dehydration rotation speed points, and this rotation speed point can be added to the calculation to obtain the reference target rotation speed and the rotation speed maintenance duration.

[0089] By adopting this implementation manner, the calculation model is used to first calculate the initial target rotation speed, and then the initial target rotation speed is used to calculate the reference target rotation speed and the rotation speed maintenance duration for controlling the rotation of the processing cylinder, which is beneficial to the reference target rotation speed calculated to fit the actual situation of the fabric. Then, the processing cylinder is controlled to rotate according to the reference target rotation speed, which is more likely to control the rotation speed of the processing cylinder within the range that can efficiently reduce the eccentricity of the fabric, so that the eccentricity reduction rate of the fabric is increased, thereby improving the dehydration efficiency.

[0090] Optionally, in an implementation manner of this embodiment, the compensation item includes an intercept term and an error term;

[0091] After weighting the eccentricity value, weight value, and centrifugal force eigenvalue, calculating an operation result between a preset compensation item and the weighted eccentricity value, weight value, and centrifugal force eigenvalue to obtain an initial target speed, includes:

[0092] y = β0 + β1·x1 + β2·x2 + β3·x1·x2 + ∈;

[0093] Wherein, y is the initial target speed, x1 is the eccentricity value, x2 is the weight value, β0 is the intercept term, β1 is the main effect weight of the eccentricity value, β2 is the main effect weight of the weight value, β3 is the interaction term weight of the eccentricity value and the weight value, and ∈ is the error term;

[0094] Wherein, β0, β1, β2, β3, and ∈ are all constant terms.

[0095] Adopting this implementation manner, the calculation process is simple, easy to save computing resources, reduce the computing cost, and improve the computing efficiency.

[0096] Optionally, in an implementation manner of this embodiment, calculating a reference target speed and a speed maintenance duration according to the initial target speed, includes:

[0097] Calculating the preset correction parameter and the initial target speed to obtain the reference target speed;

[0098] Determining the speed maintenance duration from a preset mapping relationship according to the initial target speed or the reference target speed, wherein the mapping relationship includes a corresponding relationship between the initial target speed and the speed maintenance duration or a corresponding relationship between the reference target speed and the speed maintenance duration;

[0099] Wherein, the greater the initial target speed, the greater the reference target speed.

[0100] In an embodiment, the correction parameter may be the maximum torque that the fabric processing device can output to the processing cylinder, the speed required for fabric dehydration, etc., and this embodiment does not make specific limitations thereto.

[0101] Adopting this implementation manner is conducive to further improving the fitting degree of the reference target speed with the actual situation of the fabric, thereby increasing the degree of eccentricity reduction during the rotation of the processing cylinder and improving the dehydration efficiency.

[0102] Optionally, in an implementation manner of this embodiment, after determining the reference target speed according to the eccentricity value, weight value, and centrifugal force eigenvalue, the method further includes:

[0103] If the reference target speed is less than the preset dehydration required speed, control the processing cylinder to rotate within a preset speed range, and re-obtain the eccentricity value and the weight value, so as to calculate a new reference target speed according to the re-obtained eccentricity value and weight value, until the new reference target speed is not less than the dehydration required speed or the new reference target speed is not greater than 0. Wherein, when the new reference target speed is not less than the dehydration required speed, control the processing cylinder to rotate according to the new reference target speed, and when the new reference target speed is not greater than 0, end the dehydration.

[0104] For example, when executing S100, the eccentricity value a1 and the weight value b1 are obtained; when executing S200, the initial target speed c1 and the reference target speed d1 are obtained. When d1 is less than the dehydration required speed, re-execute S100 to obtain the eccentricity value a2 and the weight value b2, and re-execute S200 according to a2 and b2 to obtain the initial target speed c2 and the reference target speed d2. If d2 is less than the dehydration required speed, loop to execute steps S100 and S200 again. If d2 is not less than the dehydration required speed, control the processing cylinder to rotate according to d2. To realize the adjustment of the eccentricity of the fabric.

[0105] It should be noted that in some cases, the re-obtained eccentricity value may become larger and larger and the weight value basically does not change. In this case, the calculated reference target speed will be 0 or a negative number, and the dehydration will end at this time.

[0106] Wherein, the dehydration required speed can be a preset speed capable of dehydrating the fabric, and this speed is greater than the speed when measuring the eccentricity value and the weight value. If the user sets the speed during dehydration, the speed set by the user is used as the dehydration required speed.

[0107] Adopting this implementation method, when the reference target speed is less than the dehydration required speed, it proves that when controlling the processing cylinder to rotate according to the reference target speed, the speed of the processing cylinder cannot reach the dehydration required speed. At this time, re-obtain the eccentricity value and the weight value. Since the processing cylinder will rotate when re-obtaining the eccentricity value and the weight value, the eccentricity degree of the fabric can be reduced slightly, so that the new reference target speed calculated according to the re-obtained eccentricity value and weight value is different from the previous one, so as to realize that through re-obtaining the eccentricity value and weight value again and again, the reference target speed is not less than the dehydration required speed, so as to ensure that the speed of the processing cylinder during dehydration can reach the dehydration required speed and improve the dehydration effect.

[0108] Optionally, in an implementation manner of this embodiment, the method further includes:

[0109] Obtain the actual maximum speed of the processing cylinder during the process of controlling the processing cylinder to rotate according to the reference target speed;

[0110] If the actual maximum rotation speed is less than the reference target rotation speed, the control processing cylinder is decelerated, and the eccentricity value and the weight value are re-acquired, so as to calculate the reference target rotation speed according to the re-acquired eccentricity value and weight value, and control the rotation of the processing cylinder according to the newly calculated reference target rotation speed to obtain a new actual maximum rotation speed until the new actual maximum rotation speed is not less than the newly calculated reference target rotation speed, and then the rotation speed of the processing cylinder is accelerated to the dehydration required rotation speed.

[0111] Adopting this implementation method, the fact that the actual maximum rotation speed is less than the reference target rotation speed proves that the rotation speed of the processing cylinder is relatively small during the actual rotation process. At this time, the eccentricity value and the weight value are re-acquired. Since the processing cylinder is controlled to rotate when the eccentricity value and the weight value are re-acquired, the eccentricity degree of the fabric can be reduced slightly, so that the new reference target rotation speed calculated according to the re-acquired eccentricity value and weight value is different from the previous one, so as to realize that through re-acquiring the eccentricity value and weight value again and again, the reference target rotation speed is not less than the dehydration required rotation speed, so as to ensure that the rotation speed of the processing cylinder can reach the dehydration required rotation speed during dehydration and improve the dehydration effect.

[0112] Optionally, in an implementation manner of this embodiment, before re-acquiring the eccentricity value and the weight value, the method further includes:

[0113] If the number of times of re-acquiring the eccentricity value and the weight value reaches a preset number threshold, the reference target rotation speed calculated last time is reduced, the rotation of the processing cylinder is controlled according to the reduced reference target rotation speed, and then the eccentricity value and the weight value are re-acquired again.

[0114] Adopting this implementation method, if the rotation speed of the processing cylinder still cannot be increased to a large extent after re-acquiring the eccentricity value and the weight value multiple times, the reference target rotation speed is directly reduced, so that the processing cylinder can realize the most basic rotation, so that the eccentricity of the fabric changes during the rotation of the processing cylinder, and then the eccentricity value and the weight value are re-acquired, which is beneficial to accelerating the rotation speed of the processing cylinder to the dehydration required rotation speed. Since the intervention method of directly reducing the reference target rotation speed is adopted, it is beneficial to quickly complete the adjustment of the eccentricity of the fabric, thereby improving the dehydration efficiency.

[0115] Optionally, in an implementation manner of this embodiment, obtaining the eccentricity value and the weight value of the fabric in the processing cylinder includes:

[0116] Controlling the processing cylinder to accelerate;

[0117] When the rotation speed of the processing cylinder reaches a preset measurement rotation speed, the eccentricity value and the weight value are obtained, where the measurement rotation speed is within a preset rotation speed range.

[0118] With this implementation method, when obtaining the eccentricity value and the weight value, the processing cylinder is controlled to increase its speed to the measurement speed, which helps to ensure the accuracy of the eccentricity value and the weight value, thereby ensuring the fit between the reference target speed and the fabric, accelerating the process of adjusting the fabric eccentricity, and improving the dehydration efficiency.

[0119] Optionally, in an implementation of this embodiment, for fabrics with different water absorption values, the corresponding measurement speeds are different, where the water absorption value is determined according to the volume and water absorption capacity of the fabric.

[0120] With this implementation method, fabrics with different water absorption values use different measurement speeds, which helps to improve the accuracy of the eccentricity value and the weight value, thereby ensuring the fit between the reference target speed and the fabric, accelerating the process of adjusting the fabric eccentricity, and improving the dehydration efficiency.

[0121] Optionally, in an implementation of this embodiment, before obtaining the eccentricity value and the weight value of the fabric in the processing cylinder, the method further includes:

[0122] Judging whether the load type of the fabric is a preset target type that is easy to absorb water;

[0123] If so, execute obtaining the eccentricity value and the weight value of the fabric in the processing cylinder.

[0124] With this implementation method, obtaining the eccentricity value and the weight value for fabrics of the target type that are easy to absorb water facilitates quickly leveling the fabrics that are easy to absorb water and improves the dehydration efficiency.

[0125] Optionally, in an implementation of this embodiment, judging whether the load type of the fabric is a preset target type that is easy to absorb water includes:

[0126] Calculating the difference between the weight of the fabric after water absorption and the weight before water absorption, and dividing the difference by the volume of the fabric to obtain the water absorption value;

[0127] If the water absorption value exceeds the preset water absorption threshold, it is judged that the load type of the fabric is the target type.

[0128] With this implementation method, the difference between the weight after water absorption and the weight before water absorption can reflect the water absorption weight of the fabric, and then dividing the difference by the volume of the fabric to obtain the water absorption value can reflect whether the fabric belongs to the load type that is easy to absorb water.

[0129] This embodiment also provides an electronic device, which includes a memory and a processor;

[0130] The memory is used to store a computer program;

[0131] The processor is used to execute the computer program to implement the steps of the above method.

[0132] This embodiment also provides a fabric processing device, which includes the above-mentioned electronic device.

[0133] This embodiment also provides a fabric processing apparatus, as Figure 2 shown, including an eccentric weighing detection module for obtaining the eccentricity value and weight value of the fabric in the processing cylinder;

[0134] a parameter calculation module for calculating an initial target rotation speed according to the eccentricity value and weight value;

[0135] a dehydration parameter control module for calculating a reference target rotation speed according to the initial target rotation speed.

[0136] After obtaining the reference target rotation speed, control the processing cylinder to rotate at the reference target rotation speed.

[0137] In a specific implementation of the embodiment of the present application, as Figure 3 shown, the dehydration control method of the fabric processing device is described as a whole.

[0138] In this specific implementation, it mainly solves the phenomenon that loads that are difficult to dehydrate do not dehydrate or the dehydration success rate is relatively low.

[0139] This control method mainly solves the dehydration of clothing loads with a small size and large water absorption as the load type.

[0140] The parameters involved in the solution are three parameters: the eccentricity value, weighing value, and rotation speed of the drum washing machine.

[0141] The eccentricity value characterizes the distribution of the load in the drum of the drum washing machine. The smaller the eccentricity value, the more uniform the distribution;

[0142] The weighing value characterizes the amount of load in the drum of the drum washing machine. The larger the weighing value, the more load in the drum;

[0143] The rotation speed refers to the optimal dehydration rotation speed point that can be achieved jointly determined by eccentricity and weighing;

[0144] The calculation method of the parameter calculation module is as follows:

[0145] y = β0 + β1·x1 + β2·x2 + β3·x1·x2 + ∈

[0146] y is the dehydration rotation speed; x1 is the eccentricity value; x2 is the weighing value; β0 is the intercept term;

[0147] β1 and β2 are respectively the main effect weights of the eccentricity value and the weighing value.

[0148] β3 is the interaction term weight of the eccentricity value and the weighing value.

[0149] ∈ is the error term.

[0150] The calculation method is obtained after data analysis and statistics in the experiment. The constant term is the design constant of this platform. This constant is obtained through regression design according to the distribution of the eccentricity value and the weighing value when designing the calculation module of the drum washing machine platform. In actual application, only the eccentricity value and the weighing value need to be obtained.

[0151] Through the calculation model of this solution, the optimal dehydration speed point in the current state can be quickly calculated based on the eccentricity and weighing, and dehydration is carried out to reduce the moisture content of the clothes, so as to make the eccentricity of the clothes decrease.

[0152] The optimal speed range obtained from the eccentricity value and the weighing value in the solution is between 90 revolutions and 160 revolutions.

[0153] After each dehydration is completed, the confirmation process of the eccentricity value and the weighing value of the clothes is carried out again, and the obtained eccentricity value and weighing value are input into the parameter calculation module again.

[0154] For the parameters obtained from the parameter calculation module, the preset target speed is obtained. Then, when entering the dehydration parameter control module and the obtained target speed is 0, the dehydration ends.

[0155] The main function of the parameter calculation module is to obtain the initial target speed of dehydration through calculation of the received eccentricity value and weighing value.

[0156] After the parameters of the initial target speed enter the dehydration parameter control module, the obtained initial target speed will be processed to obtain the actual target speed of dehydration and the speed maintenance time.

[0157] When the actual target speed obtained from the dehydration parameter control module is lower than the user-set speed (dehydration required speed), the parameter calculation of the initial target speed will be repeated.

[0158] Through the above solution, the dehydration speed execution process of the clothes in the current state can be quickly completed. In order to confirm the dehydration effect of the clothes after dehydration at the current speed, the confirmation process of weighing again is added. According to the eccentricity value and the weighing value of the clothes, the target speed for dehydration again is calculated, so that the clothes can achieve a better dehydration effect.

[0159] Such as Figure 2 As shown in a schematic diagram of speed operation, when the speed is lower than 400 revolutions and the preset target speed is reached, the speed is not maintained at this speed and immediately decelerates. The eccentricity value and the weighing value of the clothes are re-obtained and the speed is increased for dehydration again, gradually approaching the target speed set by the program.

[0160] The speed operation curve in the figure is in an increasing state. When the speed is lower than 400 revolutions, the speed at each stage is determined by the eccentricity value and the weighing value, and there may be a randomly distributed state. It is not only in an increasing state.
