[0053] 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.

[0054] 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 can mean A or B; "and / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0055] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0056] When spinning a drum washing machine, the clothes need to be evenly distributed before the machine is controlled to increase the spin speed. This is done to reduce the risk of shifting or vibrating during high-speed spinning. A typical control scheme uses extensive data experimentation to determine the speed and acceleration that most effectively distribute the load. Fixed eccentricity and weighing parameters are then set, along with a number of attempts. After repeated attempts, the speed is increased only after the clothes are evenly distributed (i.e., the eccentricity is less than a preset value). However, the speed is fixed, and if the speed cannot be increased, the cycle will be repeated, wasting time.

[0057] When dehydrating clothes, the above solution may cause repeated attempts to distribute the clothes, failing to reach the normal dehydration limit. This frequent attempts may cause the dehydration to be delayed or the clothes may not be dried.

[0058] 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:

[0059] When the drum washing machine is dehydrating clothes, there are repeated attempts to distribute the clothes, the speed and dehydration time are short, and the clothes will remain flat for a long time.

[0060] At least have the following effects:

[0061] Improve the effectiveness of the clothing dehydration process, quickly reduce the moisture content of the clothing, increase the success rate of dehydration, and reduce the time required to flatten the clothing.

[0062] At least have the following characteristics:

[0063] The eccentricity value and the weight value are obtained by eccentricity and weighing, and the eccentricity value and the weight value are used to output the vibration value so as to determine the rotation speed during dehydration according to the vibration value.

[0064] Next, the dehydration control method of the fabric processing equipment provided by this application is further described. Figure 1 The flowchart of the dehydration control method of the fabric processing equipment shown is as follows.

[0065] S100: Obtaining the eccentricity value and weight value of the fabric in the processing drum.

[0066] In one embodiment, a fabric processing device includes a processing drum for holding fabric to be processed. While the fabric is being dehydrated, the fabric is within the processing drum, and eccentricity and weight values ​​for the fabric are determined using existing algorithms or sensors. It should be noted that when measuring the eccentricity and weight values, the eccentricity and weight values ​​can be calculated or converted by detecting relevant parameters of the processing drum. In other words, the eccentricity and weight values ​​in this embodiment can be measured as a whole, with the processing drum and fabric being measured.

[0067] It should be noted that, at least when measuring the eccentricity, the rotation of the treatment drum must be controlled, and the eccentricity is determined during this rotation. During rotation, the moisture content of the fabrics and the stacking state of the fabrics change, causing the eccentricity to vary. When determining the eccentricity, the eccentricity value at the time of stabilization can be used as the eccentricity measurement result.

[0068] S102: Determine a vibration characteristic value according to the eccentricity value and the weight value and a predetermined relationship between the eccentricity value and the weight value and the vibration characteristic value.

[0069] The vibration characteristic value represents the vibration generated when the treatment drum rotates.

[0070] To determine the relationship between the eccentricity, weight, and vibration characteristic values, before executing the dehydration control method, the relationship between the three is determined by setting known eccentricity and weight values ​​and combining them with the actual collected vibration characteristic values. This allows the vibration characteristic values ​​to be determined using this relationship after the eccentricity and weight values ​​are obtained during the actual dehydration control process.

[0071] S104: Determine a reference target rotation speed according to the vibration characteristic value.

[0072] Different vibration conditions represented by the vibration characteristic values ​​have different effects on the rotational speed that the processing drum can achieve. In other words, there is a certain correspondence between the vibration characteristic values ​​and the rotational speed of the processing drum. Based on the correspondence, the reference target rotational speed can be determined when the vibration characteristic values ​​are known.

[0073] S106, controlling the treatment drum to perform dehydration treatment according to the reference target rotation speed.

[0074] In one embodiment, since the state and eccentricity of the fabric are prone to change during the rotation of the processing drum, when the rotation of the processing drum is controlled according to the reference target speed, the torque of the motor used to drive the processing drum to rotate is controlled so that the processing drum can theoretically reach the reference target speed under this torque.

[0075] Since the reference target speed is calculated based on the actual eccentricity and weight of the fabric, controlling the rotation of the processing drum according to the reference target speed is conducive to efficiently reducing the eccentricity of the fabric, allowing the processing drum to rotate at a higher speed to dehydrate the fabric.

[0076] By adopting this embodiment, by obtaining the eccentricity value and weight value of the fabric, the reference target speed calculated based on the vibration characteristic value is made to fit the actual situation of the fabric, and then the rotation of the processing drum is controlled according to the reference target speed. It is easier to control the speed of the processing drum within the range that can effectively reduce the eccentricity of the fabric, so that the eccentricity reduction rate of the fabric is increased, thereby improving the dehydration efficiency.

[0077] In a possible embodiment of the present application, the relationship between the eccentricity value, the weight value, and the vibration characteristic value includes:

[0078] The vibration characteristic value, eccentricity value and weight value satisfy the multiple regression relationship with interaction terms, eccentricity value and weight value are independent variables, and the vibration characteristic value is the dependent variable.

[0079] By adopting this implementation method, the calculation process is simple, it is easy to save computing resources, reduce computing costs, and improve dehydration efficiency.

[0080] Optionally, in an implementation of this embodiment, determining the reference target speed according to the vibration characteristic value includes:

[0081] The reference target rotational speed is determined according to the vibration characteristic value and a preset mapping relationship, wherein the mapping relationship is the relationship between the vibration characteristic value and the reference target rotational speed.

[0082] Specifically, the mapping relationship can be obtained through experiments. For example, during the experiment, the rotation of the processing drum is controlled and the vibration and rotation speed of the fabric processing equipment are monitored. After the vibration conditions are converted into vibration characteristic values, the relationship between the vibration characteristic values ​​and the rotation speed, that is, the mapping relationship, can be obtained.

[0083] Using this implementation method, the vibration characteristic value can reflect the noise and displacement conditions of the fabric processing equipment. The reference target speed determined by the vibration characteristic value is conducive to reducing noise and avoiding displacement, thereby improving the dehydration efficiency while enhancing the user experience and safety of the fabric processing equipment.

[0084] Optionally, in an implementation of this embodiment, the multiple regression relationship with the interaction term is specifically:

[0085] z=ɑ+β*x+λ*y+δ*x*y+c;

[0086] Among them, z is the vibration eigenvalue, 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.

[0087] This method simplifies the computation process, saves computational resources, reduces computational costs, and improves computational efficiency.

[0088] Optionally, in an implementation of this embodiment, the relationship between the eccentricity value and the weight value and the vibration characteristic value includes a first relationship determined under the dimension of the noise limit value, and the vibration characteristic value includes a first vibration characteristic value related to the noise limit value; and / or,

[0089] The relationship between the eccentricity value and the weight value and the vibration characteristic value includes a second relationship determined in the dimension of the device displacement, and the vibration characteristic value includes a second vibration characteristic value related to the device displacement.

[0090] Using this implementation method, the first vibration characteristic value is related to the noise limit, and the second vibration characteristic value is related to the equipment displacement, so that the reference target speed obtained according to the vibration characteristic value can not only improve the dehydration efficiency, but also enhance the user experience and safety of the fabric processing equipment.

[0091] Optionally, in an implementation of this embodiment, the first vibration characteristic value and the second vibration characteristic value represent vibration conditions at the same position on the fabric processing device.

[0092] Optionally, in an implementation of the embodiment of the present application, the first relationship satisfies:

[0093] z1=ɑ1+β1*x+λ1*y+δ1*x*y+c1;

[0094] Among them, 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.

[0095] The second relationship satisfies:

[0096] z2=ɑ2+β2*x+λ2*y+δ2*x*y+c2;

[0097] Among them, 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.

[0098] By adopting this implementation method, the first vibration eigenvalue and the second vibration eigenvalue are calculated by changing the coefficients in the formula, which is beneficial to saving computing resources, reducing computing costs, and improving computing efficiency.

[0099] Optionally, in an implementation of this embodiment, the first relationship and the second relationship are obtained in the following manner:

[0100] adjusting the weight of the fabric in the processing drum and the eccentricity of the processing drum, controlling the speed of the processing drum, collecting a first vibration value of a target position of the fabric processing device when the noise reaches a noise limit, and collecting a second vibration value of the target position when the fabric processing device is displaced, regressing the weight value, the eccentricity value, and the first vibration value to obtain a first relationship, and regressing the weight value, the eccentricity value, and the second vibration value to obtain a second relationship;

[0101] When adjusting the weight value and the eccentricity value, the weight value is first controlled to be unchanged, and the eccentricity value is adjusted to obtain the first vibration value and the second vibration value corresponding to each eccentricity value. Then, the eccentricity value is controlled to be unchanged, and the weight value is adjusted to obtain the first vibration value and the second vibration value corresponding to each weight value. Alternatively, the weight value and the eccentricity value are adjusted simultaneously to obtain the corresponding first vibration value and the second vibration value.

[0102] The target position includes the center point positions of the left and right side walls of the fabric processing equipment.

[0103] Specifically, to obtain the first and second relationships, a vibration measurement instrument is installed at the center of each of the left and right sidewalls of the fabric processing device. The vibration measurement instrument then collects vibration values. A certain weight of fabric is then placed into the processing drum, the weight of the eccentric block is adjusted to change the eccentricity, and the drum is then controlled to rotate. When the noise level reaches a limit (e.g., 65 decibels), the first set of data for the first relationship is obtained: weight value A1, eccentricity value B1, and first vibration value C1. When the fabric processing device is about to shift or has just begun to shift, the first set of data for the second relationship is obtained: weight value A1, eccentricity value B1, and second vibration value D1.

[0104] Then, keeping the weight of the fabric unchanged, adjust the weight of the eccentric block to change the eccentricity value, control the rotation of the processing cylinder, and use the same method to obtain the second set of data of the first relationship: weight value A1, eccentricity value B2 and first vibration value C2; ​​and obtain the second set of data of the second relationship: weight value A1, eccentricity value B2 and first vibration value D2.

[0105] After the eccentricity value is adjusted, the eccentricity value is kept constant and the fabric weight is changed to obtain multiple sets of data. Then, regression is performed using the sets of data of the first relationship to obtain the first relationship, and regression is performed using the sets of data of the second relationship to obtain the second relationship.

[0106] Optionally, in an implementation of this embodiment, determining the reference target speed according to the vibration characteristic value includes:

[0107] Determining a first target rotational speed for the first vibration characteristic value and a second target rotational speed for the second vibration characteristic value according to a preset mapping relationship;

[0108] The smaller one of the first target rotation speed and the second target rotation speed is used as the reference target rotation speed.

[0109] Setting the smaller one as the reference target speed can ensure that the noise and displacement of the machine are within the specified range, and there will be no excessive noise or displacement.

[0110] Optionally, in an implementation of this embodiment, controlling the processing drum to perform dehydration processing according to the reference target rotation speed includes:

[0111] The processing drum is controlled to rotate according to a reference target rotation speed to perform dehydration, wherein the number of dehydration times is different when the reference target rotation speed is different.

[0112] In one embodiment, the lower the reference target speed, the more times the spin cycle is performed. For example, if the reference target speed is not less than 800 rpm, a spin cycle is performed once; if the reference target speed is between 600-800 rpm, a spin cycle is performed twice; if the reference target speed is between 400-600 rpm, a spin cycle is performed three times; and if the reference target speed is less than 400 rpm, the reference target speed is re-determined or the spin cycle is terminated.

[0113] By adopting this implementation mode, different target rotation speeds are used and the number of dehydration times is different, 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.

[0114] Optionally, in an implementation of this embodiment, before controlling the processing drum to perform dehydration processing according to the reference target rotation speed, the method further includes:

[0115] If the reference target rotation speed is less than the preset minimum limit, the eccentricity value and weight value of the fabric in the processing drum are re-acquired to re-determine the reference target rotation speed.

[0116] The minimum limit can be set according to actual needs, such as 400 rpm, and this embodiment does not make any specific limitation on this.

[0117] With this implementation, if the obtained reference target speed is too low, dehydration is no longer performed, but the reference target speed is re-determined, which is beneficial to saving time and improving dehydration efficiency.

[0118] According to a second aspect of the embodiment of the present application, a control device is provided, such as Figure 2 As shown, it includes a measuring module for detecting the eccentricity value and weight value of the fabric in the processing drum;

[0119] a calculation module for determining a vibration characteristic value based on the eccentricity value and the weight value and a predetermined relationship between the eccentricity value and the weight value and a vibration characteristic value, and determining a reference target rotational speed based on the vibration characteristic value, wherein the vibration characteristic value represents a vibration condition generated when the processing drum rotates;

[0120] The execution module is used to control the processing drum to perform dehydration processing according to the reference target speed.

[0121] According to a third aspect of an embodiment of the present application, a fabric processing device is provided, comprising a dehydration control program, and the fabric processing device implements the above-mentioned dehydration control method when running the dehydration control program.

[0122] Optionally, in one implementation of an embodiment of the present application, when running the dehydration control program, the above-mentioned dehydration control method is performed for fabrics whose water absorption exceeds a preset water absorption threshold, whose dehydration time exceeds a preset time threshold, or whose displacement probability exceeds a preset probability threshold, wherein the displacement probability is determined based on the thickness and / or volume of the fabric.

[0123] In the above embodiments of the present application, the descriptions of the various embodiments have their own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments. The steps shown in the relevant flow charts can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flow charts, in some cases, the steps shown or described can be executed in an order different from that shown here. In other words, the order of steps described in the foregoing embodiments is only an example, and reasonable adjustment of the order of steps based on the content of the embodiments of the present application is also within the scope of protection of the embodiments of the present application.

[0124] In a specific implementation of the embodiment of the present application, the dehydration control method of the fabric processing equipment includes the following processing steps:

[0125] This solution is a dehydration control method, which mainly solves the problems of excessive vibration and noise of the washing machine during the dehydration process, as well as the phenomenon of displacement during the dehydration process.

[0126] The main target clothing load is thick load that absorbs a lot of water, takes a long time to spin, and is easy to shift during spin.

[0127] This solution places vibration value test instruments at the center points of the left and right side walls of a single model in a noise chamber. After adjusting the average load in the drum (0-15kg, in 1kg intervals) and the eccentricity (the eccentricity is adjusted by 0-2kg, in 100g intervals), the speed is increased and real-time testing is performed to record the vibration value z1 and the reference target speed r1 at the critical noise standard value (e.g., 65dB). Also, the vibration value z2 and the reference target speed r2 are recorded when the washing machine is about to be moved. The weight values, eccentricity values, and measured vibration values ​​obtained under different average load conditions are used for regression to obtain the vibration characteristic value regression equation:

[0128] z1=ɑ1+β1*x+λ1*y+δ1*x*y+c1;

[0129] Among them, 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.

[0130] z2=ɑ2+β2*x+λ2*y+δ2*x*y+c2;

[0131] Among them, 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.

[0132] The parameters involved in the plan are the eccentricity value, weight value and vibration value of the drum washing machine.

[0133] The eccentricity value represents the distribution of the load in the drum of the drum washing machine. The smaller the eccentricity characteristic value, the more uniform the distribution;

[0134] The weight value indicates the load capacity of the drum of the washing machine. The larger the weight value, the more load capacity there is in the drum.

[0135] The vibration characteristic value refers to the maximum vibration value point determined by eccentricity and weighing;

[0136] The calculation module is calculated as follows:

[0137] The calculation method of the vibration eigenvalue regression equation is obtained after data analysis and statistics in the standard experimental mode. The constant term is the design constant of the platform. In actual application, only the eccentricity value and weight value need to be obtained.

[0138] This solution uses a calculation model to quickly calculate the vibration values ​​of the two side walls in the current state based on eccentricity and weighing, compares the noise speed r1 and the upcoming shift speed r2, and takes the smaller value as the dehydration speed parameter for dehydration, which can greatly reduce the dehydration time of the washing machine.

[0139] like Figure 3 As shown, after the dehydration program is started, the speed is first increased to obtain the eccentricity value and the weight value, and two vibration characteristic values ​​are obtained according to the eccentricity value and the weight value. Two critical speeds r1 and r2 are obtained through the vibration characteristic values, and the smaller speed of r1 and r2 is taken as the actual speed for increasing the speed (that is, the reference target speed). When the corresponding speed is greater than 800, dehydration is directly performed and the dehydration is directly ended; when the speed is greater than 600 and less than 800, dehydration is terminated after two dehydrations; when the speed is greater than 400 and less than 600, dehydration is terminated after three dehydrations; when the dehydration speed is less than 400, the speed is reduced to 0 after each dehydration, and the speed is increased again after leveling for dehydration. The program ends after dehydration is repeated at most 5 times at a speed below 400.
