Description

Technical Field

[0001] This application relates to the field of garment processing equipment control, and more specifically, to a dehydration control method, equipment, and garment processing equipment. Background Technology

[0002] Clothing processing equipment refers to equipment that can process loads such as clothing. With the development of technology, current clothing processing equipment has more and more functions, including not only the commonly used washing function, but also functions such as dehydration and drying.

[0003] When a garment processing machine is dehydrating a load, the eccentricity of the load within the processing drum directly affects the drum's rotation speed. Therefore, the current method involves continuously controlling the drum's rotation or shaking before it accelerates to level the load and reduce its eccentricity.

[0004] However, for loads with large eccentricity, such as heavy clothing, the leveling process requires more steps and takes longer, and it is also prone to generating a lot of noise, which reduces the user experience of the clothing processing equipment. Summary of the Invention

[0005] This application provides a dehydration control method, device, and clothing processing device to at least solve the technical problem of decreased user experience in clothing processing devices.

[0006] According to a first aspect of the embodiments of this application, a dehydration control method is provided, applied to a garment processing device, the garment processing device including a processing drum, the method comprising:

[0007] If the initial eccentricity of the load exceeds the preset target eccentricity threshold, the processing cylinder is accelerated to the first target rotational speed according to the first target acceleration, wherein the first target acceleration is a value within the preset first target acceleration range;

[0008] Obtain the first actual eccentricity value of the load when the processing cylinder is at the first target rotational speed;

[0009] When the first actual eccentricity value exceeds the target eccentricity threshold, the eccentricity value adjustment process is executed at least once.

[0010] The eccentricity adjustment process includes: determining a new acceleration range, retrieving a new acceleration from the new acceleration range, and controlling the speed increase of the processing cylinder according to the new acceleration to adjust the eccentricity state of the load.

[0011] Using the above scheme, when the first actual eccentricity value obtained after acceleration exceeds the target eccentricity threshold, it proves that the load cannot undergo high-speed dehydration. At this point, the acceleration range is redefined, and the new acceleration within the new acceleration range is used to control the acceleration of the processing cylinder, thereby adjusting the eccentricity of the load. Because different accelerations are used to control the acceleration of the processing cylinder, and the new accelerations change with the iterative execution of the eccentricity adjustment process, it is easy to quickly reduce the eccentricity of the load, thereby improving dehydration efficiency and enhancing the user experience.

[0012] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the method further includes:

[0013] When the first actual eccentricity value exceeds the target eccentricity threshold, at least one stage adjustment is performed, and after the stage adjustment, the eccentricity value adjustment process is performed at least once iteratively.

[0014] The staged adjustment includes controlling the acceleration of the processing cylinder with an acceleration different from the first target acceleration in order to adjust the eccentricity of the load.

[0015] By employing the above scheme, before executing the eccentricity adjustment process, different accelerations are used to control the speed increase of the processing drum. This increases the drum's rotational speed to a certain value, thereby increasing the initial rotational speed of the eccentricity adjustment process, which shortens the process time and improves dewatering efficiency. Simultaneously, it adjusts the eccentricity of the load, allowing subsequent eccentricity adjustment processes to further reduce load eccentricity, thus decreasing the number of adjustment cycles and further improving dewatering efficiency.

[0016] In conjunction with the first aspect, in an optional implementation of this application embodiment, controlling the acceleration of the processing cylinder with an acceleration different from the first target acceleration to adjust the eccentricity state of the load includes:

[0017] The processing cylinder is accelerated to the second target rotational speed according to the second target acceleration. The second actual eccentricity value of the load when the processing cylinder is at the second target rotational speed is obtained. When the second actual eccentricity value exceeds the target eccentricity threshold, the next stage adjustment is performed or the eccentricity value adjustment process is performed at least once iterated. When the second actual eccentricity value does not exceed the target eccentricity threshold, the load is dehydrated according to the preset dehydration process. The second target acceleration is a value within the preset second target acceleration range.

[0018] Using the above scheme, the staged adjustment can be performed multiple times to adjust the load's eccentricity, thereby reducing the load's eccentricity. During the staged adjustment, a second actual eccentricity value is compared with the target eccentricity threshold. If the second actual eccentricity value does not exceed the target eccentricity value, the staged adjustment or eccentricity adjustment process is no longer executed, and dehydration proceeds directly according to the preset dehydration process. This reduces the number of times and the time required to adjust the load's eccentricity, improving dehydration efficiency.

[0019] In conjunction with the first aspect, in an optional implementation of this application embodiment, the eccentricity adjustment process includes:

[0020] Perform a hierarchical adjustment at least once;

[0021] The hierarchical adjustment includes: determining a new acceleration range, retrieving a new acceleration from the new acceleration range, and controlling the speed increase of the processing cylinder according to the new acceleration to adjust the eccentricity of the load.

[0022] By adopting the above scheme and continuously generating new acceleration ranges, it is helpful to find the most suitable acceleration for reducing load eccentricity, thereby reducing load eccentricity more quickly and improving dehydration efficiency.

[0023] In conjunction with the first aspect, in an optional implementation of this application embodiment, controlling the speed increase of the processing cylinder according to the new acceleration to adjust the eccentricity state of the load includes:

[0024] The processing cylinder is accelerated to the third target speed according to the new acceleration. The third actual eccentricity value of the load when the processing cylinder is at the third target speed is obtained. When the third actual eccentricity value exceeds the target eccentricity threshold, the next hierarchical adjustment is performed, the next iteration of the eccentricity value adjustment process is performed, or the dehydration is ended. When the third actual eccentricity value does not exceed the target eccentricity threshold, the load is dehydrated according to the preset dehydration process.

[0025] By adopting the above scheme, if the load eccentricity cannot be reduced below the target eccentricity threshold by measuring the degree of influence of the new acceleration on the load eccentricity, a hierarchical adjustment, eccentricity value adjustment process or termination of dehydration can be selected. In other words, different treatment methods can be selected according to the actual situation of the load to improve dehydration efficiency.

[0026] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, determining the new acceleration range includes:

[0027] If the eccentricity adjustment process is being executed for the first time, then the smaller first smaller eccentricity value is determined from the first actual eccentricity value and the second eccentricity value, and the first acceleration interval or the second acceleration interval to which the first smaller eccentricity value belongs is determined as the new acceleration interval.

[0028] If the eccentricity adjustment process is not executed for the first time, then the second smaller eccentricity value is determined from the multiple third actual eccentricity values ​​in the previous iteration process, and the new acceleration interval to which the second smaller eccentricity value belongs is determined as the new acceleration interval for this iteration.

[0029] By adopting the above scheme, the acceleration range that can reduce the load eccentricity to a smaller value is selected as the new acceleration range. By repeatedly redetermining the new acceleration range, the acceleration that is easiest to reduce and can reduce the load eccentricity to the lowest level can be obtained. This helps to reduce the number of times the load eccentricity is adjusted, thereby improving the dehydration efficiency.

[0030] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, both the first actual eccentricity value and the second actual eccentricity value are obtained in multiple ways;

[0031] The determination of the new acceleration range includes:

[0032] If the eccentricity adjustment process is being executed for the first time, then based on the size relationship of the multiple first actual eccentricities, the new acceleration range is determined using the first target acceleration corresponding to the smaller first actual eccentricity value, wherein the smaller first actual eccentricity value refers to an eccentricity value that does not exceed the maximum value among all first actual eccentricities.

[0033] If the eccentricity adjustment process is not executed for the first time, then based on the size relationship of the multiple second actual eccentricities obtained in the previous iteration, the new acceleration range in the current iteration is determined by the new acceleration corresponding to the smaller second actual eccentricity value. The smaller second actual eccentricity value refers to the eccentricity value that does not exceed the maximum value among all the second actual eccentricities obtained in the previous iteration.

[0034] Using the above scheme, selecting a smaller first actual eccentricity value or a smaller second actual eccentricity value can help obtain multiple actual eccentricity values, which helps reduce the misjudgment rate.

[0035] In conjunction with the first aspect, in an optional implementation of this application embodiment, determining the new acceleration range based on the magnitude relationship of multiple first actual eccentricity values ​​using the first target acceleration corresponding to the smaller first actual eccentricity value includes:

[0036] The interval formed by the first target acceleration corresponding to the smaller first actual eccentricity value is determined as the new acceleration interval, or the interval formed by the first target acceleration corresponding to the smallest first actual eccentricity value and the boundary value of the first target acceleration interval is determined as the new acceleration interval;

[0037] The step of determining the new acceleration range in the current iteration process based on the magnitude relationship of multiple second actual eccentricity values ​​obtained in the previous iteration, using the new acceleration corresponding to the smaller second actual eccentricity value, includes:

[0038] The interval formed by the new acceleration corresponding to the smaller second actual eccentricity value in the previous iteration is determined as the new acceleration interval, or the interval formed by the new acceleration corresponding to the smallest second actual eccentricity value in the previous iteration and the boundary value of the new acceleration interval used in the previous iteration is determined as the new acceleration interval.

[0039] By adopting the above scheme, the range of the new acceleration interval can be continuously narrowed, which helps to reduce the number of times the new acceleration interval is determined, thereby improving the dehydration efficiency.

[0040] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the method further includes:

[0041] If the new acceleration range includes only one value, then dehydration is performed using that value as the dehydration speed.

[0042] By adopting the above scheme, when the new acceleration range includes only one value, dehydration can be performed directly without iterating the eccentricity adjustment process, which is beneficial to improving dehydration efficiency.

[0043] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the method further includes:

[0044] Before performing the staged adjustment and / or the hierarchical adjustment, determine whether the current time consumed accounts for a percentage of the preset total dehydration time that exceeds a percentage threshold.

[0045] If so, the load adjustment process should be executed at least once;

[0046] If not, then perform the phased adjustment or the hierarchical adjustment.

[0047] Using the above scheme, the load adjustment process is a process that directly adjusts the load. Compared with staged or hierarchical adjustments, the load adjustment process is directly aimed at the load, which makes it easier to reduce the load's eccentricity, thereby reducing the number of staged, hierarchical, or eccentricity adjustment processes and improving dehydration efficiency.

[0048] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the load adjustment process includes:

[0049] Increase the acceleration eccentricity threshold and the speed maintenance eccentricity threshold;

[0050] The processing cylinder is controlled to accelerate under the constraint of the acceleration eccentricity threshold;

[0051] Calculate the change in rotational speed of the processing cylinder before and after speed increase;

[0052] If the speed change value exceeds the preset change threshold, the processing cylinder is controlled to slow down to the first target speed and the eccentricity value of the load is obtained to obtain the fourth actual eccentricity value. If the speed change value does not exceed the change threshold, the processing cylinder is controlled to continue to increase speed.

[0053] Determine whether the fourth actual eccentricity value is less than the target eccentricity threshold;

[0054] If so, the load is dehydrated according to the preset dehydration process; otherwise, the next load adjustment process is executed, the staged adjustment is executed, the hierarchical adjustment is executed, or the dehydration process ends.

[0055] By adopting the above scheme, the eccentricity of the load is changed by first increasing the speed and then decreasing the speed. Compared with the method of simply increasing the speed, it is easier to change the position of the load in the processing drum, the shape of the load itself, or the wrapping of the loads, which is conducive to reducing the eccentricity of the load and improving the dewatering efficiency.

[0056] In conjunction with the first aspect, in an optional implementation of this application embodiment, before executing the next load adjustment process, the method further includes:

[0057] Determine whether the number of times the load adjustment process has been executed has reached a preset threshold.

[0058] If so, determine whether the fourth actual eccentricity value obtained in the previously executed load adjustment process is the same. If they are the same, end the dehydration process and execute the staged adjustment or the hierarchical adjustment.

[0059] Using the above scheme, after reaching the threshold number of times, it is determined whether all the previous fourth actual eccentricity values ​​are the same. If they are the same, it proves that the load adjustment process cannot change the eccentricity state of the load. At this time, the staged adjustment or hierarchical adjustment is reused to change the eccentricity state of the load.

[0060] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the method further includes:

[0061] Before the processing cylinder is accelerated to the first target speed according to the first target acceleration, before the processing cylinder is accelerated to the second target speed according to the second target acceleration, and / or before the processing cylinder is accelerated to the third target speed according to the new acceleration, the processing cylinder is controlled to accelerate to the preset target speed with a preset acceleration;

[0062] The preset target speed is less than the first target speed, the second target speed, and the third target speed.

[0063] According to a second aspect of the embodiments of this application, an electronic device is provided, the electronic device including a memory and a processor;

[0064] The memory is used to store computer programs;

[0065] The processor is used to execute the computer program to implement the steps of the method described above.

[0066] According to a third aspect of the embodiments of this application, a garment processing device is provided, the garment processing device including the electronic device described above.

[0067] In conjunction with the third aspect, in one optional implementation of the embodiments of this application, the clothing processing device includes a drum washing machine.

[0068] The technical effects achieved by the second and third aspects mentioned above are similar to those achieved by the corresponding technical means in the first aspect, and will not be repeated here. Attached Figure Description

[0074] To enable those skilled in the art to better understand 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. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0075] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply differentness.

[0076] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0077] Clothing processing equipment refers to equipment that can process loads such as clothing. With the development of technology, current clothing processing equipment has more and more functions, including not only the commonly used washing function, but also functions such as dehydration and drying.

[0078] When a garment processing machine is dehydrating a load, the eccentricity of the load within the processing drum directly affects the drum's rotation speed. Therefore, the current method involves continuously controlling the drum's rotation or shaking before it accelerates to level the load and reduce its eccentricity.

[0079] However, for loads with large eccentricity, such as heavy clothing, the leveling process requires more steps and takes longer, and it is also prone to generating a lot of noise, which reduces the user experience of the clothing processing equipment.

[0080] Based on this, this application provides a dehydration control method applied to a garment processing device, the garment processing device including a processing drum, as shown in the reference. Figure 1The flowchart shown is a dehydration control method, which includes the following processing steps.

[0081] S100. If the initial eccentricity of the load exceeds the preset target eccentricity threshold, the processing cylinder is accelerated to the first target rotational speed according to the first target acceleration.

[0082] Wherein, the first target acceleration is a value within a preset first target acceleration range.

[0083] It should be noted that all garment processing equipment has a commonly used eccentricity threshold. If the eccentricity of the load exceeds this threshold, it indicates that the load cannot be directly dehydrated. The target eccentricity threshold in this embodiment is the commonly used eccentricity threshold. The specific value of the commonly used eccentricity threshold is set according to the model or type of garment processing equipment, for example, based on the maximum load weight of the garment processing equipment. This embodiment does not impose a specific limitation on this.

[0084] For ease of understanding, in one embodiment, a load with an initial eccentricity value exceeding the target eccentricity threshold is called a large eccentricity load, such as a cotton coat or clothes wrapped together. This embodiment does not specifically limit this, and any load with an initial eccentricity value exceeding the target eccentricity threshold is considered a large eccentricity load.

[0085] Because the initial eccentricity of the load exceeds the target eccentricity threshold, the garment processing equipment cannot directly drive the load to rotate at high speed. Forcibly controlling the processing drum to rotate at high speed would cause collisions or displacement of the garment processing equipment, posing a safety hazard. Therefore, in this embodiment, the processing drum is first accelerated to a first target speed using a preset first target acceleration. As long as collisions or displacement do not occur, the specific value of the first target speed is not limited.

[0086] S102. Obtain the first actual eccentricity value of the load when the processing cylinder is at the first target rotational speed.

[0087] Here, the first actual eccentricity value refers to the actual eccentricity value of the load measured when the processing cylinder is at the first target rotational speed. This embodiment does not specifically limit the method of measuring the eccentricity value.

[0088] S104. When the first actual eccentricity value exceeds the target eccentricity threshold, the eccentricity value adjustment process is executed at least once.

[0089] The eccentricity adjustment process includes: determining a new acceleration range, retrieving a new acceleration from the new acceleration range, and controlling the speed increase of the processing cylinder according to the new acceleration to adjust the eccentricity state of the load.

[0090] In one embodiment, the eccentricity adjustment process refers to a process that can adjust the eccentricity of the load. Specifically, it involves adjusting the load eccentricity by controlling the rotational speed of the processing cylinder, with the aim of reducing the load eccentricity.

[0091] Specifically, a first target acceleration range is preset. When the eccentricity adjustment process is executed, a new acceleration range is redefined, and the processing cylinder is accelerated according to the new acceleration in the new acceleration range to adjust the eccentricity of the load.

[0092] The determination of the new acceleration range can be based on the first target acceleration range or in other ways. This embodiment does not make specific limitations on this. For example, the determination of the new acceleration range is to randomly select one from multiple preset ranges.

[0093] Using the above scheme, when the first actual eccentricity value obtained after acceleration exceeds the target eccentricity threshold, it proves that the load cannot undergo high-speed dehydration. At this point, the acceleration range is redefined, and the new acceleration within the new acceleration range is used to control the acceleration of the processing cylinder, thereby adjusting the eccentricity of the load. Because different accelerations are used to control the acceleration of the processing cylinder, and the new accelerations change with the iterative execution of the eccentricity adjustment process, it is easy to quickly reduce the eccentricity of the load, thereby improving dehydration efficiency and enhancing the user experience.

[0094] In one possible embodiment of this application, the method further includes:

[0095] When the first actual eccentricity value exceeds the target eccentricity threshold, at least one stage adjustment is performed, and after the stage adjustment, the eccentricity value adjustment process is performed at least once iteratively.

[0096] The staged adjustment includes controlling the acceleration of the processing cylinder with an acceleration different from the first target acceleration in order to adjust the eccentricity of the load.

[0097] In one embodiment, adjusting the load eccentricity can be understood as including two modules: the first module is a staged adjustment, and the second module is an eccentricity value adjustment process. The two modules are executed cyclically, resulting in a load eccentricity adjustment process as follows: staged adjustment - eccentricity value adjustment process - staged adjustment - eccentricity value adjustment process - staged adjustment - eccentricity value adjustment process - ... eccentricity value adjustment process.

[0098] Optionally, in one implementation of this embodiment, controlling the acceleration of the processing cylinder with an acceleration different from the first target acceleration to adjust the eccentricity of the load includes:

[0099] The processing cylinder is accelerated to the second target rotational speed according to the second target acceleration. The second actual eccentricity value of the load when the processing cylinder is at the second target rotational speed is obtained. When the second actual eccentricity value exceeds the target eccentricity threshold, the next stage adjustment is performed or the eccentricity value adjustment process is performed at least once iterated. When the second actual eccentricity value does not exceed the target eccentricity threshold, the load is dehydrated according to the preset dehydration process. The second target acceleration is a value within the preset second target acceleration range.

[0100] The second target acceleration can be less than, greater than or equal to, the first target acceleration; this embodiment does not impose a specific limitation on this. The second actual eccentricity value refers to the actual eccentricity value of the load when the processing cylinder is at the second target rotational speed.

[0101] If the second actual eccentricity value does not exceed the target eccentricity threshold, it proves that the eccentricity value of the load has been reduced to a level that allows for normal dehydration. This means that the high-speed rotation of the processing drum can be controlled to complete the dehydration, and therefore the load can be dehydrated directly according to the preset dehydration process. The preset dehydration process refers to a commonly used dehydration process in clothing processing equipment, and this embodiment does not specifically limit it.

[0102] If the second actual eccentricity value exceeds the target eccentricity threshold, it proves that the eccentricity value of the load is still very large, and it is impossible to directly control the high-speed rotation of the processing cylinder for dehydration. Therefore, it is necessary to choose to execute the next stage adjustment or execute at least one iteration of the eccentricity adjustment process. Whether to execute the stage adjustment or the eccentricity adjustment process can be set according to the actual situation. This embodiment does not make specific limitations on this.

[0103] Using the above scheme, the staged adjustment can be performed multiple times to adjust the load's eccentricity, thereby reducing the load's eccentricity. During the staged adjustment, a second actual eccentricity value is compared with the target eccentricity threshold. If the second actual eccentricity value does not exceed the target eccentricity value, the staged adjustment or eccentricity adjustment process is no longer executed, and dehydration proceeds directly according to the preset dehydration process. This reduces the number of times and the time required to adjust the load's eccentricity, improving dehydration efficiency.

[0104] Optionally, in one implementation of this embodiment, the eccentricity adjustment process includes:

[0105] Perform a hierarchical adjustment at least once;

[0106] The hierarchical adjustment includes: determining a new acceleration range, retrieving a new acceleration from the new acceleration range, and controlling the speed increase of the processing cylinder according to the new acceleration to adjust the eccentricity of the load.

[0107] In other words, each time the eccentricity adjustment process is executed, a hierarchical adjustment can be performed only once or multiple times. This embodiment does not specifically limit this.

[0108] For tiered adjustments, first determine the new acceleration range, then retrieve the new acceleration to control the speed increase of the processing cylinder until the processing cylinder can no longer increase its speed, so that the processing cylinder maintains a certain rotation speed.

[0109] During the acceleration and speed maintenance processes, the eccentricity of the load is prone to change, thus enabling the adjustment of the eccentricity.

[0110] By adopting the above scheme and continuously generating new acceleration ranges, it is helpful to find the most suitable acceleration for reducing load eccentricity, thereby reducing load eccentricity more quickly and improving dehydration efficiency.

[0111] Optionally, in one implementation of this embodiment, controlling the speed increase of the processing cylinder according to the new acceleration to adjust the eccentricity of the load includes:

[0112] The processing cylinder is accelerated to the third target speed according to the new acceleration. The third actual eccentricity value of the load when the processing cylinder is at the third target speed is obtained. When the third actual eccentricity value exceeds the target eccentricity threshold, the next hierarchical adjustment is performed, the next iteration of the eccentricity value adjustment process is performed, or the dehydration is ended. When the third actual eccentricity value does not exceed the target eccentricity threshold, the load is dehydrated according to the preset dehydration process.

[0113] The third target rotational speed can be greater than or equal to the second target rotational speed, but it cannot be less than the second target rotational speed. The third actual eccentricity value is similar to the second actual eccentricity value, and will not be elaborated further.

[0114] If the third actual eccentricity value exceeds the target eccentricity threshold, it proves that the load eccentricity is too large. Therefore, the next hierarchical adjustment, the next iteration of the eccentricity value adjustment process, or the dehydration process is terminated is executed. Which one is executed can be set according to the actual situation, and this embodiment does not make a specific limitation on this.

[0115] By adopting the above scheme, if the load eccentricity cannot be reduced below the target eccentricity threshold by measuring the degree of influence of the new acceleration on the load eccentricity, a hierarchical adjustment, eccentricity value adjustment process or termination of dehydration can be selected. In other words, different treatment methods can be selected according to the actual situation of the load to improve dehydration efficiency.

[0116] Optionally, in one implementation of this embodiment, determining the new acceleration range includes:

[0117] If the eccentricity adjustment process is being executed for the first time, then the smaller first smaller eccentricity value is determined from the first actual eccentricity value and the second eccentricity value, and the first acceleration interval or the second acceleration interval to which the first smaller eccentricity value belongs is determined as the new acceleration interval.

[0118] If the eccentricity adjustment process is not executed for the first time, then the second smaller eccentricity value is determined from the multiple third actual eccentricity values ​​in the previous iteration process, and the new acceleration interval to which the second smaller eccentricity value belongs is determined as the new acceleration interval for this iteration.

[0119] In one embodiment, when the eccentricity adjustment process is executed for the first time, if the first smaller eccentricity value is the first actual eccentricity value, then the first acceleration interval is determined as the new acceleration interval; if the first smaller eccentricity value is the second actual eccentricity value, then the second acceleration interval is determined as the new acceleration interval. For subsequent executions, a new acceleration interval is determined from the previously determined new acceleration intervals. For ease of understanding, since the eccentricity adjustment process can include multiple hierarchical adjustments, each hierarchical adjustment corresponds to a new acceleration interval. For example, if there are three new acceleration intervals, then one of these three is selected when determining the new acceleration interval for the next iteration.

[0120] By adopting the above scheme, the acceleration range that can reduce the load eccentricity to a smaller value is selected as the new acceleration range. By repeatedly redetermining the new acceleration range, the acceleration that is easiest to reduce and can reduce the load eccentricity to the lowest level can be obtained. This helps to reduce the number of times the load eccentricity is adjusted, thereby improving the dehydration efficiency.

[0121] Optionally, in one implementation of this embodiment, both the first actual eccentricity value and the second actual eccentricity value are obtained in multiple ways;

[0122] The determination of the new acceleration range includes:

[0123] If the eccentricity adjustment process is being executed for the first time, then based on the size relationship of the multiple first actual eccentricities, the new acceleration range is determined using the first target acceleration corresponding to the smaller first actual eccentricity value, wherein the smaller first actual eccentricity value refers to an eccentricity value that does not exceed the maximum value among all first actual eccentricities.

[0124] If the eccentricity adjustment process is not executed for the first time, then based on the size relationship of the multiple second actual eccentricities obtained in the previous iteration, the new acceleration range in the current iteration is determined by the new acceleration corresponding to the smaller second actual eccentricity value. The smaller second actual eccentricity value refers to the eccentricity value that does not exceed the maximum value among all the second actual eccentricities obtained in the previous iteration.

[0125] Using the above scheme, selecting a smaller first actual eccentricity value or a smaller second actual eccentricity value can help obtain multiple actual eccentricity values, which helps reduce the misjudgment rate.

[0126] Optionally, in one implementation of this embodiment, determining the new acceleration range based on the magnitude relationship of multiple first actual eccentricity values ​​using the first target acceleration corresponding to the smaller first actual eccentricity value includes:

[0127] The interval formed by the first target acceleration corresponding to the smaller first actual eccentricity value is determined as the new acceleration interval, or the interval formed by the first target acceleration corresponding to the smallest first actual eccentricity value and the boundary value of the first target acceleration interval is determined as the new acceleration interval;

[0128] The step of determining the new acceleration range in the current iteration process based on the magnitude relationship of multiple second actual eccentricity values ​​obtained in the previous iteration, using the new acceleration corresponding to the smaller second actual eccentricity value, includes:

[0129] The interval formed by the new acceleration corresponding to the smaller second actual eccentricity value in the previous iteration is determined as the new acceleration interval, or the interval formed by the new acceleration corresponding to the smallest second actual eccentricity value in the previous iteration and the boundary value of the new acceleration interval used in the previous iteration is determined as the new acceleration interval.

[0130] In one embodiment, the smaller value can be either less than the maximum value or less than the intermediate value.

[0131] By adopting the above scheme, the range of the new acceleration interval can be continuously narrowed, which helps to reduce the number of times the new acceleration interval is determined, thereby improving the dehydration efficiency.

[0132] Optionally, in one implementation of this embodiment, the method further includes:

[0133] If the new acceleration range includes only one value, then dehydration is performed using that value as the dehydration speed.

[0134] Since the range of the new acceleration is constantly shrinking, it will eventually include only one value. At this point, it is no longer possible to further refine the acceleration value. Instead, the acceleration value can be used directly to control the speed increase of the processing cylinder to complete the dehydration.

[0135] By adopting the above scheme, when the new acceleration range includes only one value, dehydration can be performed directly without iterating the eccentricity adjustment process, which is beneficial to improving dehydration efficiency.

[0136] Optionally, in one implementation of this embodiment, the method further includes:

[0137] Before performing the staged adjustment and / or the hierarchical adjustment, determine whether the current time consumed accounts for a percentage of the preset total dehydration time that exceeds a percentage threshold.

[0138] If so, the load adjustment process should be executed at least once;

[0139] If not, then perform the phased adjustment or the hierarchical adjustment.

[0140] In one embodiment, the load adjustment process refers to a process that adjusts the eccentricity of the load in a manner different from the staged adjustment and eccentricity adjustment processes.

[0141] Using the above scheme, the load adjustment process is a process that directly adjusts the load. Compared with staged or hierarchical adjustments, the load adjustment process is directly aimed at the load, which makes it easier to reduce the load's eccentricity, thereby reducing the number of staged, hierarchical, or eccentricity adjustment processes and improving dehydration efficiency.

[0142] Optionally, in one implementation of this embodiment, the load adjustment process includes:

[0143] Increase the acceleration eccentricity threshold and the speed maintenance eccentricity threshold;

[0144] The processing cylinder is controlled to accelerate under the constraint of the acceleration eccentricity threshold;

[0145] Calculate the change in rotational speed of the processing cylinder before and after speed increase;

[0146] If the speed change value exceeds the preset change threshold, the processing cylinder is controlled to slow down to the first target speed and the eccentricity value of the load is obtained to obtain the fourth actual eccentricity value. If the speed change value does not exceed the change threshold, the processing cylinder is controlled to continue to increase speed.

[0147] Determine whether the fourth actual eccentricity value is less than the target eccentricity threshold;

[0148] If so, the load is dehydrated according to the preset dehydration process; otherwise, the next load adjustment process is executed, the staged adjustment is executed, the hierarchical adjustment is executed, or the dehydration process ends.

[0149] When the speed change exceeds the threshold value, it indicates a significant change in the load's eccentricity, moving towards reducing the eccentricity. This causes a large change in the processing drum's speed. At this point, the fourth actual eccentricity value can be obtained to determine if it is less than the target eccentricity threshold. Otherwise, the speed is increased further to attempt to reduce the load's eccentricity.

[0150] By adopting the above scheme, the eccentricity of the load is changed by first increasing the speed and then decreasing the speed. Compared with the method of simply increasing the speed, it is easier to change the position of the load in the processing drum, the shape of the load itself, or the wrapping of the loads, which is conducive to reducing the eccentricity of the load and improving the dewatering efficiency.

[0151] Optionally, in one implementation of this embodiment, before executing the next load adjustment process, the method further includes:

[0152] Determine whether the number of times the load adjustment process has been executed has reached a preset threshold.

[0153] If so, determine whether the fourth actual eccentricity value obtained in the previously executed load adjustment process is the same. If they are the same, end the dehydration process and execute the staged adjustment or the hierarchical adjustment.

[0154] For ease of understanding, for example, if the threshold for the number of times is 3, then the fourth actual eccentricity value will be obtained 3 times. If the three fourth actual eccentricity values ​​are the same, it proves that the load adjustment process can no longer play a role in adjusting the eccentricity state. At this time, the dehydration can be stopped or other adjustments can be made.

[0155] Using the above scheme, after reaching the threshold number of times, it is determined whether all the previous fourth actual eccentricity values ​​are the same. If they are the same, it proves that the load adjustment process cannot change the eccentricity state of the load. At this time, the staged adjustment or hierarchical adjustment is reused to change the eccentricity state of the load.

[0156] Optionally, in one implementation of this embodiment, the method further includes:

[0157] Before the processing cylinder is accelerated to the first target speed according to the first target acceleration, before the processing cylinder is accelerated to the second target speed according to the second target acceleration, and / or before the processing cylinder is accelerated to the third target speed according to the new acceleration, the processing cylinder is controlled to accelerate to the preset target speed with a preset acceleration;

[0158] The preset target speed is less than the first target speed, the second target speed, and the third target speed.

[0159] In the above embodiments of this application, the descriptions of each embodiment have their own emphasis. Parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments. The steps illustrated in the related flowcharts can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown here. In other words, the order of steps described in the foregoing embodiments is merely an example. Reasonable adjustments to the order of steps based on the content of the embodiments of this application are also within the protection scope of the embodiments of this application.

[0160] In one specific implementation of this application embodiment, the dehydration control method includes the following processing steps:

[0161] like Figure 2-4 As shown, the first stage:

[0162] Speed-up stage a: The washing machine gradually increases the drum speed from a stationary state. The purpose of this stage is to initially spread the clothes out so that they can be more evenly distributed on the drum wall.

[0163] Speed-up stage b: In this stage, the washing machine will further increase the drum speed to a higher level, so as to use centrifugal force to bring the clothes closer to the drum wall, forming a relatively stable distribution state, and identifying the eccentric distribution state of the current clothing load.

[0164] The second stage: This stage is executed when the eccentricity limit during the first stage is not met. If the first stage meets the acceleration limit, this stage is not required. Acceleration and dehydration control is completed in the first stage.

[0165] Acceleration stage a: In this stage, the acceleration from speed a to speed b is changed to further adjust the distribution of clothing.

[0166] Acceleration stage b: This is the second stage of high-speed acceleration, and the goal is to detect whether the eccentricity value of the clothing distribution meets the eccentricity limit requirements for dehydration.

[0167] The third stage: This stage is executed when the eccentricity limit during the second stage is not met. If the second stage meets the acceleration limit, this stage is not required, and the acceleration dehydration control is completed in the second stage.

[0168] Acceleration stage a: As the final adjustment, the acceleration from speed a to speed b in the third stage is changed again to readjust the distribution of clothing and reduce the eccentricity during dehydration.

[0169] Acceleration stage b: This is the third high-speed detection stage, the purpose of which is to confirm whether the distribution of clothing meets the eccentricity limit requirements for dehydration.

[0170] By controlling the drum speed in stages, this method enables precise management of clothing distribution, reduces imbalance caused by uneven clothing distribution, improves spin-drying efficiency while reducing noise and vibration, and enhances the user experience of the washing machine.

[0171] The preferred speed for acceleration stage a is from 0 to 45 rpm, with an optimal acceleration time greater than 2 seconds and less than or equal to 6 seconds (this time includes the acceleration and maintenance at 45 rpm). Accelerate to 45 rpm with a first fixed acceleration.

[0172] The second acceleration stage b is the clothing status recognition stage. The speed is increased by a second fixed acceleration, preferably from 45 rpm to 93 rpm, and then maintained at 93 rpm for a period of time. The total time of stage b is 10-15 seconds. Then the speed is reduced to the initial speed of stage a. During the period of maintaining the speed (such as 93 rpm), the load eccentricity value is identified.

[0173] If the detected load eccentricity value is less than the maximum limit for this stage, the speed will continue to increase to the next speed detection stage. The preferred maximum speed is 120 rpm, 150 rpm, or 180 rpm, but it is not limited to these three speed settings. The detection speed for the next stage is not shown in the diagram, in order to further confirm the load eccentricity status.

[0174] If the identified load eccentricity value is greater than or equal to the maximum limit of this stage, the speed is reduced to the initial velocity of stage a; then the next clothing distribution stage (second and third) is carried out.

[0175] Unlike stage a, stage b is divided into multiple sub-stages b.1, b.2, ..., bn. The optimal recognition time for clothing eccentricity in each adjacent sub-stage is less than or equal to 5 seconds.

[0176] When the system first reaches this stage, the first stage of eccentricity state identification is performed. If the limit is met, the second stage of eccentricity state confirmation is then performed. In the two sub-stages of the first, second, and third stages, the first fixed acceleration is the same, but the second fixed acceleration is different. The second fixed acceleration is determined based on the detected eccentricity value, which is the smallest among the previously detected eccentricity values.

[0177] In stage b.1 of the identification process, an optimal range for the eccentricity value is set. If the value does not meet this range limit, the speed is reduced to the starting speed point of the next state distribution. This limit range varies depending on the dynamic balancing system of the overall machine structure. Once the overall machine structure is determined, there is a definite set range (the maximum allowable eccentricity value without collision with the drum). The value within this range also characterizes the eccentricity state of the clothing.

[0178] When accelerating from speed stage a to speed stage b, the second fixed acceleration setting is divided into three different acceleration intervals, each corresponding to a different acceleration range:

[0179] First acceleration zone: Acceleration is set between 8 rpm / s and 15 rpm / s (including boundary values). This means that in this stage, the increase in acceleration is relatively gentle, adapting to loads with heavy or large areas of clothing.

[0180] The second acceleration range: the acceleration is set between 35 rpm / s and 45 rpm / s (including the boundary values). This indicates that in this acceleration phase, the acceleration is significantly increased, which means that the speed of rotation increases more rapidly. This is suitable for loads of highly absorbent clothing, quickly raising the clothing to the target speed so that the clothing is evenly distributed.

[0181] The third acceleration zone: the acceleration is adjusted to between 18 rpm / s and 25 rpm / s (including the boundary value). This means that in the third stage, the acceleration is between the first two zones, and this stage is used to compensate for any unevenness in the distribution of clothing that may exist in the first two stages.

[0182] By strategically adjusting these different acceleration zones, the acceleration process can be precisely controlled to adapt to the needs of different clothing distributions.

[0183] In the three major stages, in the first cycle, the acceleration in the first acceleration range is preferred in the first stage, the acceleration in the second acceleration range is preferred in the second stage, and the acceleration in the third acceleration range is preferred in the third stage. After entering the second cycle, the second fixed acceleration is preferred to run at the second fixed acceleration corresponding to the stage with the smallest eccentricity value in the previous cycle.

[0184] When the above three speed ranges are executed for the first time, their acceleration parameters are executed sequentially in the first, second, and third cycles to control the acceleration process. The time during the acceleration process is determined by the actual acceleration. After determining the target speed of stage b, the speed is increased from stage a to the target speed of stage b according to the set acceleration. The optimal range for the speed maintenance time of stage b is 0 to 5 seconds.

[0185] The rule for determining the second fixed acceleration is as follows: if, after three consecutive cycles, the eccentricity detected in stage b of the speed identification process does not meet the eccentricity requirements for accelerated dehydration, then the eccentricity values ​​in stage b within the three cycles are statistically analyzed. The acceleration with the highest frequency of the smallest eccentricity value is used to determine which acceleration interval it falls into. Before this process, each acceleration falls within the three ranges mentioned above, and one parameter is selected as the acceleration setpoint for each interval. If the smallest eccentricity values ​​in the three stages are concentrated within one acceleration interval, then subsequent accelerations will fall within that interval, and the three latest acceleration control parameters will be selected, according to the following rules:

[0186] There is a detailed method for adjusting the second fixed acceleration during the acceleration process from speed a to speed b, which optimizes the rate of acceleration to the dehydration speed. The following is a summary of this method:

[0187] 1. Confirm the second fixed acceleration: First, select an acceleration value from the three determined acceleration ranges as the "second fixed acceleration" during the acceleration process.

[0188] 2. Selecting Acceleration Within an Interval: When setting the acceleration, priority should be given to the upper bound (Amax), lower bound (Amin), and median value (Amed) of the interval. The selection principle is to try one of these three values ​​first in order to find the optimal acceleration.

[0189] 3. Monitoring Acceleration Status: If, under a set acceleration, the washing machine still cannot reach the spin speed required for spin-drying in three consecutive cycles, the frequency of acceleration values ​​with frequent small eccentricities will be identified and recorded. This step helps determine whether the current acceleration value is causing the difficulty in accelerating.

[0190] 4. Adjust the acceleration range: Based on the acceleration values ​​with higher frequency of smaller eccentricities in three consecutive cycles, determine which set range the acceleration falls within. Then, adjust the acceleration range to Amin to Amed or Amed to Amax within that range and try the dehydration process again.

[0191] 5. Reset acceleration parameters: Based on the new range, reset the acceleration parameters according to the previously mentioned maximum, minimum, and median rules. The system will attempt to increase the speed to the dehydration speed again. If the target is still not reached, the adjustment will be repeated until the three acceleration settings are the same or the preset maximum time is reached.

[0192] This method attempts to find the optimal parameters that ensure effective dehydration without causing excessive wear or dehydration failure due to improper acceleration. Throughout the process, logical judgments and parameter adjustments are repeatedly performed until the best acceleration setting is found.

[0193] The first, second, and third intervals of the second fixed acceleration, which were initially confirmed, are used as the default parameter intervals. After finding the optimal state distribution acceleration, it will not affect the next spin cycle in this washing process. The acceleration for the next spin cycle will need to be reset.

[0194] The above process is to quickly find the speed, time, and acceleration parameters that are optimal for adapting to the dehydrated clothing.

[0195] During the three-stage cyclic dehydration process, if the current dehydration process has occupied more than 50% of the total dehydration time set by the program during the clothing status recognition in one of the b stages, then the load status adjustment stage will be entered.

[0196] If 50% of the program's set time has not been reached, the current operation process will continue.

[0197] Before entering the load adjustment stage, the eccentricity threshold of the eccentricity identification state in the speed b stage is increased, and the threshold of the maximum eccentricity state value in the ab stage of the acceleration process is increased to d. If the current eccentricity value meets the set threshold, the load adjustment stage is entered; otherwise, the dehydration process ends.

[0198] In each cycle of the three-stage cyclic dehydration process, the dehydration speed corresponding to d and the duration of that speed are different. The maximum threshold increases to 60% of the limit state where no machine failure occurs in speed stage b. The corresponding speed, duration, and number of repetitions are determined by the threshold d. If, after repeating the dehydration speed corresponding to the threshold at least twice, the threshold is the same as the previous two times on the third repetition, the load adjustment stage is considered to be over, and dehydration ends. If the third repetition is different from the previous two, the load adjustment process continues, or dehydration continues when the threshold of the normal dehydration stage is met.

[0199] During the three-stage cyclic dehydration process, if the detected load eccentricity value is less than the maximum limit for that stage, the speed is increased to the next speed detection stage. The preferred maximum speeds are 120 rpm, 150 rpm, and 180 rpm. The rule for determining the maximum speed is that the target speed reached by the newly added speed greater than stage b, and its maintenance time, are determined by the difference between the state change and the threshold during operation. If the state change is less than the set threshold during operation, the speed is increased until the threshold is reached (the change in eccentricity is less than the threshold value, so the speed is increased). During continuous operation, if the state change is greater than the threshold, the maintenance state ends, and the speed is reduced to a speed less than the threshold. If the state change gradually becomes less than the threshold, the speed is increased again until the state change reaches the threshold speed. Until the set maintenance period ends, if the state change and the threshold remain unchanged (proving that the eccentricity value has stopped changing), it indicates that the load state adjustment has been completed within the threshold range. The system needs to go through the speed b stage again to identify the change in speed (reducing to 93 RPM). If the change in speed matches the normal speed-up status, the speed will be increased directly. If it still does not match, the system will re-enter the load status adjustment stage. The maximum number of attempts in the load status adjustment stage is set, and this number is determined by the different types of clothing loads or different washing program modes.

[0200] In summary, this invention mainly addresses the issues of slow spin-drying and high moisture content in drum washing machines. By selecting the acceleration in the ab stage as a leveling parameter for rapid adjustment, it adapts the optimal parameter to the load. By adjusting the load's moisture content in the speed identification stage, it brings the load's moisture content within a certain range, thereby improving the spin-drying success rate and spin-drying speed, and reducing the load's moisture content during spin-drying.
