[0002] A fabric processing device refers to a device for processing 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

[0013] By adopting this implementation, the first vibration eigenvalue is related to the noise limit value, and the second vibration eigenvalue is related to the device displacement, so that the reference target rotational speed obtained according to the vibration eigenvalue can not only improve the dehydration efficiency, but also enhance the use experience and use safety of the fabric processing device.

[0014] In combination with the first aspect, in an alternative implementation of the embodiments of the present application, the first vibration eigenvalue and the second vibration eigenvalue represent the vibration conditions at the same position on the fabric processing device.

[0015] In combination with the first aspect, in an alternative implementation of the embodiments of the present application, the first relationship satisfies: z1 = ɑ1 + β1 * x + λ1 * y + δ1 * x * y + c1; Wherein, z1 is the first vibration eigenvalue, x is the eccentricity value, y is the weight value, ɑ1 is the first intercept term, β1 is the first main effect weight of the eccentricity value, λ1 is the first main effect weight of the weight value, δ1 is the first interaction term weight of the eccentricity value and the weight value, and c1 is the first error term.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] 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 accompanying 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.

[0029] 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 there can be three relationships, for example, A and / or B, which can 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 limit to be different.

[0030] 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 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 not clearly listed or inherent to these process, method, product or device.

[0031] When a drum washing machine dewater clothes, it is necessary to evenly distribute the clothes and then control it to increase the speed for dehydration. The purpose of doing this is to reduce the phenomenon that the washing machine shifts or vibrates greatly during high-speed dehydration. The general control scheme is to find the rotation speed and acceleration at which the load is more easily evenly distributed through a large number of data experiments, set fixed eccentricity and weighing parameters and the number of attempts. Through repeated attempts, when it is detected that the clothes are evenly distributed, that is, when the eccentricity value is less than the preset value, the speed can be increased. The rotation speed for increasing the speed is fixed, and it will repeat continuously when the speed cannot be increased, wasting time.

[0032] In the above scheme, when dealing with clothes dehydration, there is a state where the clothes are repeatedly tried to be distributed and cannot reach below the eccentricity limit value for normal dehydration. The number of attempts is relatively large, resulting in dehydration delay or the phenomenon that the clothes cannot be dried.

[0033] Based on this, the embodiments of the present application provide a dehydration control method, a control device and a fabric processing device for a fabric processing device, which at least solve the following problems: When a drum washing machine dewater clothes, there is a repeated distribution process, the rotation speed dehydration time is short, and the clothes will be in a leveling state for a long time.

[0034] It has at least the following effects: Improve the effectiveness of the clothes dehydration process, quickly reduce the moisture content of the clothes, improve the success rate of dehydration, and reduce the time required for the clothes to be leveled.

[0035] It has at least the following characteristics: Obtain the eccentricity value and the weight value through eccentricity and weighing, output the vibration value by using the eccentricity value and the weight value, so as to determine the rotation speed during dehydration according to the vibration value.

[0036] Next, the dehydration control method of the fabric processing device provided by the present application will be further described. Refer to Figure 1 As shown in the schematic flow chart of the dehydration control method of the fabric processing device, the method includes the following processing procedures.

[0037] S100. Obtain the eccentricity value and the weight value of the fabric in the processing cylinder.

[0038] 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 in the processing cylinder, and the eccentricity value and the weight value of the fabric are obtained by using the existing algorithm or sensor. It should be noted that when measuring the eccentricity value and the weight value, the eccentricity value and the weight value can be calculated or converted by detecting the relevant parameters of the processing cylinder. That is to say, in this embodiment, when measuring the eccentricity value and the weight value, the processing cylinder and the fabric can be measured as a whole.

[0039] It should be noted that at least when measuring the eccentricity value, it is necessary to control the rotation of the processing cylinder. 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 changes in the eccentricity value. When determining the eccentricity value, the eccentricity value when it stabilizes can be used as the measurement result of each eccentricity value.

[0040] S102. Determine the vibration characteristic value according to the eccentricity value, the weight value, and the relationship between the pre-determined eccentricity value, weight value, and vibration characteristic value.

[0041] Among them, the vibration characteristic value characterizes the vibration situation generated when the processing cylinder rotates.

[0042] In order to obtain the relationship between the eccentricity value, the weight value, and the vibration characteristic value, before executing this dehydration control method, the relationship among the three is determined by setting known eccentricity values and weight values and combining the actually collected vibration characteristic values. So that during the actual dehydration control process, after obtaining the eccentricity value and the weight value, the vibration characteristic value can be determined using this relationship.

[0043] S104. Determine the reference target speed according to the vibration characteristic value.

[0044] The vibration situations characterized by the vibration characteristic values are different, and the influence on the speed that the processing cylinder can reach is different. That is to say, there is a certain corresponding relationship between the vibration characteristic value and the speed of the processing cylinder. According to the corresponding relationship, the reference target speed can be determined when the vibration characteristic value is known.

[0045] S106. Control the processing cylinder to perform dehydration treatment according to the reference target speed.

[0046] In one embodiment, since the state and eccentricity of the fabric are likely to change during the rotation of the processing cylinder, when controlling the rotation of the processing cylinder according to the reference target 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 speed under this torque.

[0047] Since the reference target speed is calculated based on the actual eccentricity value and weight value of the fabric, controlling the rotation of the processing cylinder according to the reference target speed is beneficial to efficiently reduce the eccentricity value of the fabric, enabling the processing cylinder to rotate at a higher speed to dehydrate the fabric.

[0048] Adopting this embodiment, by obtaining the eccentricity value and weight value of the fabric, the reference target speed calculated according to the vibration characteristic value fits the actual situation of the fabric. Then, controlling the rotation of the processing cylinder according to the reference target speed is more likely to control the speed of the processing cylinder within the range that can efficiently reduce the eccentricity of the fabric, increasing the rate of eccentricity reduction of the fabric, thereby improving the dehydration efficiency.

[0049] In a possible embodiment of the present application, the relationship between the eccentricity value, the weight value and the vibration characteristic value includes: The vibration characteristic value, the eccentricity value and the weight value satisfy a multiple regression relationship with interaction terms, where the eccentricity value and the weight value are independent variables and the vibration characteristic value is the dependent variable.

[0050] Adopting this implementation method, the calculation process is simple, easy to save computing resources, reduce the computing cost, and improve the dehydration efficiency.

[0051] Optionally, in an implementation manner of this embodiment, determining the reference target rotation speed according to the vibration characteristic value includes: Determining the reference target rotation speed according to the vibration characteristic value and a preset mapping relationship, where the mapping relationship is the relationship between the vibration characteristic value and the reference target rotation speed.

[0052] Specifically, the mapping relationship can be obtained through experiments. For example, during the experiment, control the rotation of the processing cylinder and monitor the vibration condition and rotation speed of the fabric processing device. After converting the vibration condition into a vibration characteristic value, the relationship between the vibration characteristic value and the rotation speed, that is, the mapping relationship, can be obtained.

[0053] Adopting this implementation method, the vibration characteristic value can reflect the noise condition and displacement condition of the fabric processing device. The reference target rotation speed determined by the vibration characteristic value is beneficial to reducing noise and avoiding displacement, so as to improve the dehydration efficiency while enhancing the use experience and use safety of the fabric processing device.

[0054] Optionally, in an implementation manner of this embodiment, the multiple regression relationship with interaction terms is specifically: z = ɑ + β * x + λ * y + δ * x * y + c; Where z is the vibration characteristic value, x is the eccentricity value, y is the weight value, ɑ is the intercept term, β is the main effect weight of the eccentricity value, λ is the main effect weight of the weight value, δ is the interaction term weight of the eccentricity value and the weight value, and c is the error term.

[0055] Adopting this implementation method, the calculation process is simple, easy to save computing resources, reduce the computing cost, and improve the computing efficiency.

[0056] Optionally, in an implementation manner of this embodiment, the relationship between the eccentricity value, the weight value and the vibration characteristic value includes a first relationship determined in the dimension of the noise limit, and the vibration characteristic value includes a first vibration characteristic value related to the noise limit; and / or, The relationship between the eccentricity value, the weight value and the vibration characteristic value includes a second relationship determined in the dimension of the equipment displacement, and the vibration characteristic value includes a second vibration characteristic value related to the equipment displacement.

[0057] With this implementation method, the first vibration eigenvalue is related to the noise limit value, and the second vibration eigenvalue is related to the displacement of the device, so that the reference target rotational speed obtained based on the vibration eigenvalue can improve the dehydration efficiency while enhancing the user experience and usage safety of the fabric processing device.

[0058] Optionally, in an implementation manner of this embodiment, the first vibration eigenvalue and the second vibration eigenvalue represent the vibration conditions at the same position on the fabric processing device.

[0059] Optionally, in an implementation manner of this application embodiment, the first relationship satisfies: z1 = ɑ1 + β1 * x + λ1 * y + δ1 * x * y + c1; where z1 is the first vibration eigenvalue, x is the eccentricity value, y is the weight value, ɑ1 is the first intercept term, β1 is the first main effect weight of the eccentricity value, λ1 is the first main effect weight of the weight value, δ1 is the first interaction term weight of the eccentricity value and the weight value, and c1 is the first error term. The second relationship satisfies: z2 = ɑ2 + β2 * x + λ2 * y + δ2 * x * y + c2; where z2 is the second vibration eigenvalue, x is the eccentricity value, y is the weight value, ɑ2 is the second intercept term, β2 is the second main effect weight of the eccentricity value, λ2 is the second main effect weight of the weight value, δ2 is the second interaction term weight of the eccentricity value and the weight value, and c2 is the second error term.

[0060] With this implementation method, by changing the coefficients in the formula to calculate the first vibration eigenvalue and the second vibration eigenvalue, it is beneficial to save computing resources, reduce computing costs, and improve computing efficiency.

[0061] Optionally, in an implementation manner of this embodiment, the first relationship and the second relationship are obtained in the following way: Adjust the weight value of the fabric in the processing cylinder and the eccentricity value of the processing cylinder, control the processing cylinder to increase speed, collect the first vibration value at the target position of the fabric processing device when the noise reaches the noise limit value, and collect the second vibration value at the target position when the fabric processing device is displaced. Perform regression on the weight value, eccentricity value, and the first vibration value to obtain the first relationship, and perform regression on the weight value, eccentricity value, and the second vibration value to obtain the second relationship; Among them, when adjusting the weight value and the eccentricity value, first control the weight value to remain unchanged, adjust the eccentricity value, and obtain the first vibration value and the second vibration value corresponding to each eccentricity value. Then control the eccentricity value to remain unchanged, adjust the weight value, and obtain the first vibration value and the second vibration value corresponding to each weight value, or adjust the weight value and the eccentricity value simultaneously to obtain the corresponding first vibration value and the second vibration value; Among them, the target position includes the center point positions of the left and right side walls of the fabric processing device.

[0062] That is to say, in order to obtain the first relationship and the second relationship, a vibration value testing instrument is installed at the center point positions of the left and right side walls of the fabric processing device, and the vibration values are collected through the vibration value testing instrument. Then, a certain weight of fabric is placed into the processing cylinder, the weight of the eccentric block is adjusted to change the eccentricity value, and then the processing cylinder is controlled to rotate. When the noise reaches the noise limit value (such as 65 decibels), the first set of data of the first relationship is obtained: the weight value A1, the eccentricity value B1, and the first vibration value C1; when the fabric processing device is about to shift or just starts to shift, the first set of data of the second relationship is obtained: the weight value A1, the eccentricity value B1, and the second vibration value D1.

[0063] Then, while keeping the weight of the fabric unchanged, the weight of the eccentric block is adjusted to change the eccentricity value, the processing cylinder is controlled to rotate, and the same method is used to obtain the second set of data of the first relationship: the weight value A1, the eccentricity value B2, and the first vibration value C2; and the second set of data of the second relationship: the weight value A1, the eccentricity value B2, and the second vibration value D2.

[0064] After the adjustment of the eccentricity value is completed, while keeping the eccentricity value unchanged, the fabric weight is changed to obtain multiple sets of data. Then, several sets of data of the first relationship are used for regression to obtain the first relationship, and several sets of data of the second relationship are used for regression to obtain the second relationship.

[0065] Optionally, in an implementation manner of this embodiment, determining the reference target rotation speed according to the vibration characteristic value includes: Determining the first target rotation speed of the first vibration characteristic value and the second target rotation speed of the second vibration characteristic value according to the preset mapping relationship; Taking the smaller one of the first target rotation speed and the second target rotation speed as the reference target rotation speed.

[0066] Setting the smaller one as the reference target rotation speed can ensure that the noise and shift of the machine are within the limited range, and there will be no phenomenon of excessive noise or shift.

[0067] Optionally, in an implementation manner of this embodiment, controlling the processing cylinder to perform dehydration treatment according to the reference target rotation speed includes: Controlling the processing cylinder to rotate according to the reference target rotation speed for dehydration. Among them, when the reference target rotation speeds are different, the number of dehydration times is different.

[0068] In one embodiment, the smaller the reference target speed is, the greater the number of dehydration times. For example, if the reference target speed is not less than 800 rpm, dehydration is performed once; if the reference target speed is between 600 - 800 rpm, dehydration is performed twice; if the reference target speed is between 400 - 600 rpm, dehydration is performed three times; if the reference target speed is less than 400 rpm, the reference target speed is re - determined or dehydration is ended.

[0069] Adopting this implementation method, different reference target speeds result in different dehydration times, which is beneficial to improving the dehydration effect, reducing the moisture content of the fabric after dehydration, and improving the dehydration quality of the fabric processing equipment.

[0070] Optionally, in an implementation manner of this embodiment, before controlling the processing cylinder to perform dehydration treatment according to the reference target speed, the method further includes: If the reference target speed is less than the preset minimum limit value, the eccentricity value and weight value of the fabric in the processing cylinder are re - obtained to re - determine the reference target speed.

[0071] Among them, the minimum limit value can be set according to actual needs, such as 400 rpm, and this embodiment does not make specific limitations on this.

[0072] Adopting this implementation method, if the obtained reference target speed is too small, dehydration is not performed, but the reference target speed is re - determined, which is beneficial to saving time and improving dehydration efficiency.

[0073] According to the second aspect of the embodiments of the present application, a control device is provided, as Figure 2 shown, including a measurement module for detecting the eccentricity value and weight value of the fabric in the processing cylinder; a calculation module for determining the vibration characteristic value according to the eccentricity value, weight value, and the pre - determined relationship between the eccentricity value, weight value, and the vibration characteristic value, and determining the reference target speed according to the vibration characteristic value, where the vibration characteristic value characterizes the vibration condition generated when the processing cylinder rotates; an execution module for controlling the processing cylinder to perform dehydration treatment according to the reference target speed.

[0074] According to the third aspect of the embodiments of the present application, a fabric processing equipment is provided, including a dehydration control program. When the fabric processing equipment runs the dehydration control program, the above - mentioned dehydration control method is implemented.

[0075] Optionally, in an implementation manner of the embodiments of the present application, when running the dehydration control program, the above - mentioned dehydration control method is executed for fabrics with a water absorption amount exceeding the preset water absorption threshold, a dehydration time exceeding the preset time threshold, or a shift probability exceeding the preset probability threshold, where the shift probability is determined according to the thickness and / or volume of the fabric.

[0076] In the above embodiments of the present application, the descriptions of the respective embodiments have their own emphases. For parts not detailed in a certain embodiment, reference may be made to the relevant descriptions of other embodiments. The steps shown in the relevant flowcharts can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of the steps described in the foregoing embodiments is only an example, and a reasonable adjustment of the step order based on the content of the embodiments of the present application is also within the protection scope of the embodiments of the present application.

[0077] In a specific implementation of the embodiment of the present application, the dehydration control method of the fabric treatment device includes the following processing procedures: This solution is a dehydration control method, which mainly solves the problems of excessive vibration value and excessive noise during the dehydration process, and the phenomenon of displacement during the dehydration process.

[0078] It mainly aims at thick loads with large water absorption, long dehydration time, and easy displacement during dehydration.

[0079] In this solution, vibration value testing instruments are arranged at the center points of the left and right side walls of a single model in a noise chamber. After adjusting the uniform load weight in the drum (0 - 15 kg, at 1 kg intervals) and the eccentricity value (adjusting the eccentricity value of the eccentric block from 0 to 2 kg, at 100 g intervals), the vibration value z1 and the reference target speed r1 are measured and recorded in real time when the noise standard critical value (such as 65 dB) is reached during the speed increase; and the vibration value z2 and the reference target speed r2 when the washing machine is about to shift. Using the weight values, eccentricity values, and measured vibration values under different uniform loads obtained from the tests for regression, the vibration characteristic value regression equation is obtained: z1 = ɑ1 + β1 * x + λ1 * y + δ1 * x * y + c1; Where, z1 is the first vibration characteristic value, x is the eccentricity value, y is the weight value, ɑ1 is the first intercept term, β1 is the first main effect weight of the eccentricity value, λ1 is the first main effect weight of the weight value, δ1 is the first interaction term weight of the eccentricity value and the weight value, and c1 is the first error term.

[0080] z2 = ɑ2 + β2 * x + λ2 * y + δ2 * x * y + c2; Where, z2 is the second vibration characteristic value, x is the eccentricity value, y is the weight value, ɑ2 is the second intercept term, β2 is the second main effect weight of the eccentricity value, λ2 is the second main effect weight of the weight value, δ2 is the second interaction term weight of the eccentricity value and the weight value, and c2 is the second error term.

[0081] The parameters involved in the solution are three parameters: the eccentricity value, the weight value, and the vibration value of the drum washing machine.

[0082] The eccentricity value characterizes the distribution of the load inside the drum of the drum washing machine. The smaller the eccentricity characteristic value, the more uniform the distribution. The weight value characterizes the amount of load inside the drum of the drum washing machine. The larger the weight value, the more load there is inside the drum. The vibration characteristic value refers to the maximum vibration value point jointly determined by eccentricity and weighing. The calculation method of the calculation module is as follows: The calculation method of the vibration characteristic value regression equation is obtained after data analysis and statistics in the standard experimental mode. The constant term is the design constant of this platform. In actual application, only the eccentricity value and the weight value need to be obtained.

[0083] In this solution, through the calculation model, the vibration values of the two side walls in the current state are quickly calculated based on eccentricity and weighing. By comparing the noise rotation speed r1 and the upcoming shifting rotation speed r2, the smaller value is taken as the dehydration rotation speed parameter for dehydration, which can greatly reduce the dehydration time of the washing machine.

[0084] As Figure 3 shown, after the dehydration program is started, it first accelerates to obtain the eccentricity value and the weight value. Two vibration characteristic values are obtained based on the eccentricity value and the weight value. Two critical rotation speeds r1 and r2 are obtained through the vibration characteristic values. The smaller rotation speed of r1 and r2 is taken as the actual acceleration rotation speed (i.e., the reference target rotation speed). When the corresponding rotation speed is greater than 800, direct dehydration is carried out and the dehydration ends directly; when the rotation speed is greater than 600 and less than 800, dehydration is carried out twice and then the dehydration ends; when the rotation speed is greater than 400 and less than 600, dehydration is carried out three times and the dehydration ends; when the dehydration rotation speed is less than 400, after each dehydration, it decelerates to 0 again, levels off and then accelerates again for dehydration. The program ends after repeating the dehydration below 400 at most 5 times.
