Description

Technical Field

[0001] The present application relates to the field of control of clothing processing equipment, and in particular, to a dehydration control method, equipment and clothing processing equipment. Background Art

[0002] Clothes processing equipment refers to equipment that can process loads such as clothes. With the development of technology, current clothes processing equipment has more and more functions. In addition to the commonly used washing function, it also includes dehydration, drying and other functions.

[0003] When a laundry machine spins a load, the eccentricity of the load within the spin drum directly affects the spin speed. Therefore, the current approach involves continuously rotating or shaking the spin drum before it speeds up to level the load and reduce eccentricity.

[0004] However, for loads with large eccentricity, such as heavy clothes, the number of times to level them is large, the time is long, and it is easy to generate loud noise, which reduces the user experience of the clothing processing equipment. Summary of the Invention

[0005] The embodiments of the present application provide a dehydration control method, device, and clothing processing device to at least solve the technical problem of reduced user experience of clothing processing devices.

[0006] According to a first aspect of an embodiment of the present application, a dehydration control method is provided, which is applied to a clothes processing device, wherein the clothes processing device includes a processing drum, and the method includes:

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

[0008] acquiring a first actual eccentricity value of the load when the processing drum is at the first target rotational speed;

[0009] When the first actual eccentricity value exceeds the target eccentricity threshold, iteratively executing the eccentricity value adjustment process at least once;

[0010] The eccentricity value adjustment process includes: determining a new acceleration interval, retrieving a new acceleration from the new acceleration interval, and controlling the speed of the processing drum according to the new acceleration to adjust the eccentricity of the load.

[0011] With this approach, if the first actual eccentricity value obtained after speed increases exceeds the target eccentricity threshold, indicating that the load cannot be dehydrated at high speed, the acceleration range is redefined and the new acceleration within this range is used to control the speed of the processing drum, thereby adjusting the load's eccentricity. Because different accelerations are used to control the speed of the processing drum, and the new accelerations change with each iteration of the eccentricity adjustment process, the load's eccentricity can be quickly reduced, thereby improving dehydration efficiency and enhancing the user experience.

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

[0013] When the first actual eccentricity value exceeds the target eccentricity threshold, performing at least one stage adjustment and performing the at least one iterative eccentricity value adjustment process after the stage adjustment;

[0014] The stage-by-stage adjustment includes controlling the speed of the processing drum to increase at an acceleration different from the first target acceleration, so as to adjust the eccentric state of the load.

[0015] With this solution, before executing the eccentricity adjustment process, different accelerations are first used to control the speed of the treatment drum. This can increase the speed of the treatment drum to a certain value, thereby increasing the initial speed of the eccentricity adjustment process, shortening the eccentricity adjustment process time and improving dehydration efficiency. At the same time, it can also adjust the eccentricity of the load, which is conducive to further reducing the eccentricity of the load in the subsequent eccentricity adjustment process, thereby reducing the number of eccentricity adjustment processes and improving dehydration efficiency.

[0016] In conjunction with the first aspect, in an optional implementation of the embodiment of the present application, controlling the speed of the processing drum to increase with an acceleration different from the first target acceleration to adjust the eccentric state of the load includes:

[0017] The processing drum is accelerated to the second target speed according to the second target acceleration, and the second actual eccentricity value of the load when the processing drum is at the second target 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 iteratively performed at least once. When the second actual eccentricity value does not exceed the target eccentricity threshold, the load is dehydrated according to the preset dehydration process, wherein the second target acceleration is a value within the preset second target acceleration range.

[0018] Using the above solution, the staged adjustment can be performed multiple times to adjust the load's eccentricity multiple times, thereby reducing the load's eccentricity. During the staged adjustment, the 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 value adjustment process is no longer performed, and dehydration is directly carried out according to the preset dehydration process. This reduces the number and time of load eccentricity adjustments and improves dehydration efficiency.

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

[0020] Perform at least one hierarchical adjustment;

[0021] The hierarchical adjustment includes: executing the determination of a new acceleration interval, retrieving a new acceleration from the new acceleration interval, and controlling the speed increase of the processing drum according to the new acceleration to adjust the eccentric state of the load.

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

[0023] In combination with the first aspect, in an optional implementation of the embodiment of the present application, controlling the speed of the processing drum according to the new acceleration to adjust the eccentric state of the load includes:

[0024] According to the new acceleration, the processing drum is accelerated to the third target speed, and the third actual eccentricity value of the load when the processing drum 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] With the above solution, if the eccentricity of the load cannot be reduced to below the target eccentricity threshold by the degree of influence of the new acceleration on the load, you can choose to perform hierarchical adjustment, eccentricity value adjustment process or end dehydration, that is, you can choose different processing methods according to the actual situation of the load to improve dehydration efficiency.

[0026] In conjunction with the first aspect, in an optional implementation of the embodiment of the present application, determining the new acceleration range includes:

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

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

[0029] By adopting the above scheme, an acceleration interval that can reduce the eccentricity of the load to a smaller value is selected as the new acceleration interval. By re-determining the new acceleration interval multiple times, the acceleration that is easiest to reduce and can reduce the eccentricity of the load to the lowest can be obtained, which helps to reduce the number of times the eccentricity of the load is adjusted, thereby improving the dehydration efficiency.

[0030] In combination with the first aspect, in an optional implementation of the embodiment of the present application, a plurality of first actual eccentricity values ​​and a plurality of second actual eccentricity values ​​are obtained;

[0031] Determining the new acceleration range includes:

[0032] If the eccentricity adjustment process is executed for the first time, the new acceleration range is determined using the first target acceleration corresponding to the smaller first actual eccentricity value according to the magnitude relationship of the plurality of first actual eccentricity values, wherein the smaller first actual eccentricity value refers to an eccentricity value that does not exceed the maximum value among all the first actual eccentricity values;

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

[0034] By adopting the above solution, selecting a smaller first actual eccentricity value or selecting a smaller second actual eccentricity value is helpful in obtaining multiple actual eccentricity values, which helps to reduce the misjudgment rate.

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

[0036] Determining an interval formed by the first target acceleration corresponding to the smaller first actual eccentricity value as the new acceleration interval, or determining an interval formed by the first target acceleration corresponding to the smallest first actual eccentricity value and a boundary value of the first target acceleration interval as the new acceleration interval;

[0037] The determining of a new acceleration range in this iteration process by using the new acceleration corresponding to the smaller second actual eccentricity value according to the magnitude relationship of the plurality of second actual eccentricity values ​​obtained in the previous iteration process includes:

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

[0039] By adopting the above solution, the range of the new acceleration interval can be continuously narrowed, which is conducive to reducing 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 embodiment of the present application, the method further includes:

[0041] If the new acceleration interval includes only one value, the dehydration is performed with the value as the dehydration speed.

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

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

[0044] Before executing the stage-by-stage adjustment and / or executing the hierarchical adjustment, determining whether the ratio of the current spent time to the preset total dehydration time exceeds a ratio threshold;

[0045] If so, the load adjustment process is performed at least once;

[0046] If not, the staged adjustment or the hierarchical adjustment is performed.

[0047] With the above solution, the load adjustment process is a process for directly adjusting the load. Compared with the stage adjustment or hierarchical adjustment, the load adjustment process is directly targeted at the load, which makes it easier to reduce the eccentricity of the load, thereby reducing the number of stage adjustment, hierarchical adjustment or eccentricity value adjustment processes and improving the dehydration efficiency.

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

[0049] Increase the speed-up eccentricity threshold and the speed-maintaining eccentricity threshold;

[0050] Controlling the processing drum to increase speed under the constraint of the speed increase eccentricity threshold;

[0051] Calculating the change in speed of the treatment drum before and after the speed increase;

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

[0053] determining 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, the stage adjustment, the hierarchical adjustment or the dehydration is terminated.

[0055] By adopting the above scheme, the eccentric state of the load is changed by first increasing the speed and then decreasing the speed. Compared with the method of only 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 situation between the loads, thereby facilitating the subsequent reduction of the eccentricity of the load and improving the dehydration efficiency.

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

[0057] Determining whether the load regulation process has been executed a certain number of times or not has reached a preset threshold value;

[0058] If so, it is determined whether the fourth actual eccentricity value obtained in the previously executed load adjustment process is the same. If the fourth actual eccentricity value is the same, the dehydration is terminated, the stage-by-stage adjustment is performed, or the hierarchical adjustment is performed.

[0059] Using the above scheme, after reaching the number threshold, 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 stage adjustment or hierarchical adjustment is used again to change the eccentricity state of the load.

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

[0061] Before increasing the speed of the processing drum to the first target speed according to the first target acceleration, before increasing the speed of the processing drum to the second target speed according to the second target acceleration, and / or before increasing the speed of the processing drum to the third target speed according to the new acceleration, controlling the processing drum to increase the speed to the preset target speed at a preset acceleration;

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

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

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

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

[0066] According to a third aspect of an embodiment of the present application, a clothing processing device is provided, which includes the electronic device described above.

[0067] In combination with the third aspect, in an optional implementation of the embodiment of the present application, the clothing processing device includes a drum washing machine.

[0068] The technical effects obtained in the above-mentioned second to third aspects are similar to the technical effects obtained by the corresponding technical means in the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] 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.

[0075] It should be understood that the “plurality” mentioned herein refers to two or more than two. 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 can 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 limit certain different

[0076] 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.

[0077] Clothes processing equipment refers to equipment that can process loads such as clothes. With the development of technology, current clothes processing equipment has more and more functions. In addition to the commonly used washing function, it also includes dehydration, drying and other functions.

[0078] When a laundry machine spins a load, the eccentricity of the load within the spin drum directly affects the spin speed. Therefore, the current approach involves continuously rotating or shaking the spin drum before it speeds up to level the load and reduce eccentricity.

[0079] However, for loads with large eccentricity, such as heavy clothes, the number of times to level them is large, the time is long, and it is easy to generate loud noise, which reduces the user experience of the clothing processing equipment.

[0080] Based on this, the embodiment of the present application provides a dehydration control method, which is applied to a clothes processing device, wherein the clothes processing device includes a processing drum, Figure 1The flow chart of the dehydration control method shown in FIG. 1 includes the following processing steps.

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

[0082] The first target acceleration is a value within a preset first target acceleration range.

[0083] It should be noted that laundry processing equipment generally has a commonly used eccentricity threshold. If the load eccentricity exceeds this commonly used eccentricity threshold, the load cannot be directly dehydrated. The target eccentricity threshold in this embodiment is a commonly used eccentricity threshold. The specific value of the commonly used eccentricity threshold is set according to the model or type of the laundry processing equipment, for example, according to the maximum load weight of the laundry processing equipment, and this embodiment does not specifically limit this.

[0084] For ease of understanding, in one embodiment, a load whose initial eccentricity value exceeds the target eccentricity threshold is called a large eccentricity load, such as a cotton coat or clothes wrapped together. This embodiment does not make specific limitations on this. As long as the initial eccentricity value exceeds the target eccentricity threshold, the load is considered a large eccentricity load.

[0085] Because the load's initial eccentricity exceeds the target eccentricity threshold, the laundry processing device cannot directly drive the load to rotate at high speed. Forcibly controlling the processing drum to rotate at high speed could cause the drum to collide or the clothing processing device to shift, 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 collision or shifting does not occur, the specific value of the first target speed is not limited.

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

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

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

[0089] The eccentricity value adjustment process includes: determining a new acceleration interval, retrieving a new acceleration from the new acceleration interval, and controlling the speed of the processing drum according to the new acceleration to adjust the eccentricity of the load.

[0090] In one embodiment, the eccentricity value adjustment process refers to a process capable of adjusting the eccentricity of the load, which specifically adjusts the eccentricity of the load by controlling the rotation speed of the processing drum, and the purpose of the adjustment is to reduce the eccentricity of the load.

[0091] Specifically, a first target acceleration interval is preset. When the eccentricity value adjustment process is executed, a new acceleration interval is re-determined, and the processing tube speed is increased according to the new acceleration control in the new acceleration interval to adjust the eccentricity state of the load.

[0092] The new acceleration interval may be determined based on the first target acceleration interval or in other ways, which is not specifically limited in this embodiment. For example, the new acceleration interval may be determined by randomly selecting one from a plurality of preset intervals.

[0093] With this approach, if the first actual eccentricity value obtained after speed increases exceeds the target eccentricity threshold, indicating that the load cannot be dehydrated at high speed, the acceleration range is redefined and the new acceleration within this range is used to control the speed of the processing drum, thereby adjusting the load's eccentricity. Because different accelerations are used to control the speed of the processing drum, and the new accelerations change with each iteration of the eccentricity adjustment process, the load's eccentricity can be quickly reduced, thereby improving dehydration efficiency and enhancing the user experience.

[0094] In a possible embodiment of the present application, the method further includes:

[0095] When the first actual eccentricity value exceeds the target eccentricity threshold, performing at least one stage adjustment and performing the at least one iterative eccentricity value adjustment process after the stage adjustment;

[0096] The stage-by-stage adjustment includes controlling the speed of the processing drum to increase at an acceleration different from the first target acceleration, so as to adjust the eccentric state of the load.

[0097] In one embodiment, adjusting the load eccentricity can be understood as comprising two modules: a first module for staged adjustment, and a second module for the eccentricity value adjustment process. The two modules are executed cyclically, resulting in a load eccentricity adjustment process that follows the following sequence: 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 an implementation of this embodiment, controlling the speed of the processing drum to increase at an acceleration different from the first target acceleration to adjust the eccentric state of the load includes:

[0099] The processing drum is accelerated to the second target speed according to the second target acceleration, and the second actual eccentricity value of the load when the processing drum is at the second target 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 iteratively performed at least once. When the second actual eccentricity value does not exceed the target eccentricity threshold, the load is dehydrated according to the preset dehydration process, wherein the second target acceleration is a value within the preset second target acceleration range.

[0100] The second target acceleration may be less than the first target acceleration, or may be greater than or equal to the first target acceleration, which is not specifically limited in this embodiment. The second actual eccentricity value refers to the actual eccentricity value of the load when the processing drum is at the second target speed.

[0101] If the second actual eccentricity value does not exceed the target eccentricity threshold, it indicates that the eccentricity of the load has been reduced to a value suitable for normal dehydration. In other words, the processing drum can be controlled to rotate at a high speed to complete dehydration. Therefore, the load can be directly dehydrated according to the preset dehydration process. The preset dehydration process refers to a dehydration process commonly used in clothing processing equipment and is not specifically limited in this embodiment.

[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 processing drum to rotate at high speed for dehydration. Therefore, it is selected to execute the next stage adjustment or to execute at least one iteration of the eccentricity value adjustment process. Whether to execute the stage adjustment or the eccentricity value adjustment process can be set according to the actual situation, and this embodiment does not make specific restrictions on this.

[0103] Using the above solution, the staged adjustment can be performed multiple times to adjust the load's eccentricity multiple times, thereby reducing the load's eccentricity. During the staged adjustment, the 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 value adjustment process is no longer performed, and dehydration is directly carried out according to the preset dehydration process. This reduces the number and time of load eccentricity adjustments and improves dehydration efficiency.

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

[0105] Perform at least one hierarchical adjustment;

[0106] The hierarchical adjustment includes: executing the determination of a new acceleration interval, retrieving a new acceleration from the new acceleration interval, and controlling the speed increase of the processing drum according to the new acceleration to adjust the eccentric state of the load.

[0107] That is, each time the eccentricity adjustment process is executed, the hierarchical adjustment may be performed only once, or may be performed multiple times, which is not specifically limited in this embodiment.

[0108] For the hierarchical adjustment, a new acceleration range is first determined, and then the new acceleration is used to control the speed of the processing cylinder until the processing cylinder cannot be accelerated, so that the processing cylinder rotates at a constant speed.

[0109] During the speed increase process and the speed maintenance process, the eccentricity state of the load is easy to change, thereby achieving the adjustment of the eccentricity state.

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

[0111] Optionally, in an implementation of this embodiment, controlling the speed of the processing drum according to the new acceleration to adjust the eccentric state of the load includes:

[0112] According to the new acceleration, the processing drum is accelerated to the third target speed, and the third actual eccentricity value of the load when the processing drum 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 speed may be greater than the second target speed, or may be equal to the second target speed, but may not be less than the second target speed. The third actual eccentricity value is similar to the second actual eccentricity value and will not be described in detail.

[0114] If the third actual eccentricity value exceeds the target eccentricity threshold, it indicates that the load eccentricity is too large, and the next hierarchical adjustment is performed, the next iteration of the eccentricity value adjustment process is performed, or the dehydration is terminated. Which one is performed can be set according to actual conditions and is not specifically limited in this embodiment.

[0115] With the above solution, if the eccentricity of the load cannot be reduced to below the target eccentricity threshold by the degree of influence of the new acceleration on the load, you can choose to perform hierarchical adjustment, eccentricity value adjustment process or end dehydration, that is, you can choose different processing methods according to the actual situation of the load to improve dehydration efficiency.

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

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

[0118] If the eccentricity value adjustment process is not executed for the first time, a second smaller eccentricity value is determined from the multiple third actual eccentricity values ​​of the previous iteration process, and the new acceleration interval to which the second smaller eccentricity value belongs is determined as the new acceleration interval of 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, the first acceleration interval is determined as the new acceleration interval; if the first smaller eccentricity value is the second actual eccentricity value, the second acceleration interval is determined as the new acceleration interval. When the process is not executed for the first time, 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, one of these three will be selected when determining the new acceleration interval for the next iteration.

[0120] By adopting the above scheme, an acceleration interval that can reduce the eccentricity of the load to a smaller value is selected as the new acceleration interval. By re-determining the new acceleration interval multiple times, the acceleration that is easiest to reduce and can reduce the eccentricity of the load to the lowest can be obtained, which helps to reduce the number of times the eccentricity of the load is adjusted, thereby improving the dehydration efficiency.

[0121] Optionally, in an implementation of this embodiment, a plurality of the first actual eccentricity value and the second actual eccentricity value are obtained;

[0122] Determining the new acceleration range includes:

[0123] If the eccentricity adjustment process is executed for the first time, the new acceleration range is determined using the first target acceleration corresponding to the smaller first actual eccentricity value according to the magnitude relationship of the plurality of first actual eccentricity values, wherein the smaller first actual eccentricity value refers to an eccentricity value that does not exceed the maximum value among all the first actual eccentricity values;

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

[0125] By adopting the above solution, selecting a smaller first actual eccentricity value or selecting a smaller second actual eccentricity value is helpful in obtaining multiple actual eccentricity values, which helps to reduce the misjudgment rate.

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

[0127] Determining an interval formed by the first target acceleration corresponding to the smaller first actual eccentricity value as the new acceleration interval, or determining an interval formed by the first target acceleration corresponding to the smallest first actual eccentricity value and a boundary value of the first target acceleration interval as the new acceleration interval;

[0128] The determining of a new acceleration range in this iteration process by using the new acceleration corresponding to the smaller second actual eccentricity value according to the magnitude relationship of the plurality of second actual eccentricity values ​​obtained in the previous iteration process includes:

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

[0130] In one embodiment, the smaller value may be a value smaller than the maximum value, or a value smaller than the middle value.

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

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

[0133] If the new acceleration interval includes only one value, the dehydration is performed with the value as the dehydration speed.

[0134] Since the range of the new acceleration interval is constantly shrinking, it will only include one value in the end. At this time, it is impossible to further refine the acceleration value. The acceleration value can be directly used to control the speed of the processing drum to complete the dehydration.

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

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

[0137] Before executing the stage-by-stage adjustment and / or executing the hierarchical adjustment, determining whether the ratio of the current spent time to the preset total dehydration time exceeds a ratio threshold;

[0138] If so, the load adjustment process is performed at least once;

[0139] If not, the staged adjustment or the hierarchical adjustment is performed.

[0140] In one embodiment, the load adjustment process refers to a process for adjusting the eccentricity of the load in a manner different from the stage-by-stage adjustment and eccentricity value adjustment processes.

[0141] With the above solution, the load adjustment process is a process for directly adjusting the load. Compared with the stage adjustment or hierarchical adjustment, the load adjustment process is directly targeted at the load, which makes it easier to reduce the eccentricity of the load, thereby reducing the number of stage adjustment, hierarchical adjustment or eccentricity value adjustment processes and improving the dehydration efficiency.

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

[0143] Increase the speed-up eccentricity threshold and the speed-maintaining eccentricity threshold;

[0144] Controlling the processing drum to increase speed under the constraint of the speed increase eccentricity threshold;

[0145] Calculating the change in speed of the treatment drum before and after the speed increase;

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

[0147] determining 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, the stage adjustment, the hierarchical adjustment or the dehydration is terminated.

[0149] When the speed change exceeds the change threshold, it indicates that the load eccentricity has significantly changed, and is changing in a direction that reduces the eccentricity, causing a significant change in the processing drum speed. At this point, the fourth actual eccentricity value can be obtained to determine whether it is less than the target eccentricity threshold. Otherwise, the speed is continued to increase in an attempt to reduce the load eccentricity.

[0150] By adopting the above scheme, the eccentric state of the load is changed by first increasing the speed and then decreasing the speed. Compared with the method of only 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 situation between the loads, thereby facilitating the subsequent reduction of the eccentricity of the load and improving the dehydration efficiency.

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

[0152] Determining whether the load regulation process has been executed a certain number of times or not has reached a preset threshold value;

[0153] If so, it is determined whether the fourth actual eccentricity value obtained in the previously executed load adjustment process is the same. If the fourth actual eccentricity value is the same, the dehydration is terminated, the stage-by-stage adjustment is performed, or the hierarchical adjustment is performed.

[0154] For ease of understanding, for example, if the number threshold is 3, three fourth actual eccentricity values ​​will be obtained. 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, dehydration can be terminated or other adjustments can be made.

[0155] Using the above scheme, after reaching the number threshold, 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 stage adjustment or hierarchical adjustment is used again to change the eccentricity state of the load.

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

[0157] Before increasing the speed of the processing drum to the first target speed according to the first target acceleration, before increasing the speed of the processing drum to the second target speed according to the second target acceleration, and / or before increasing the speed of the processing drum to the third target speed according to the new acceleration, controlling the processing drum to increase the speed to the preset target speed at a preset acceleration;

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

[0159] 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.

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

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

[0162] Stage A: The washing machine gradually increases the drum speed from a standstill. This stage aims to spread the clothes out and distribute them more evenly across the drum walls.

[0163] Speed-up stage B: In this stage, the washing machine will further increase the speed of the drum to a higher level to push the clothes closer to the drum wall through centrifugal force, 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 speed increase is not met in the first stage. If the first stage meets the speed increase, this stage does not need to be executed, and the speed increase and dehydration control is completed in the first stage.

[0165] Speed-up stage a: In this stage, the acceleration from speed a to speed b is changed to further adjust the distribution of the clothes.

[0166] Speed-up stage B: This is the second stage of high-speed increase, the goal of which is to detect whether the eccentricity value of the distribution state of the clothes meets the eccentricity limit requirement of dehydration.

[0167] The third stage: This stage is executed when the eccentricity limit during speed increase is not met in the second stage. If the second stage meets the speed increase, this stage does not need to be executed, and the speed increase and dehydration control is completed in the second stage.

[0168] Speed-up stage a: As the final adjustment, the acceleration from speed a to speed b in the third stage is changed again, and the distribution of clothes is adjusted again to reduce the eccentricity during dehydration.

[0169] Speed-up stage B: This is the high-speed detection stage of the third stage, the purpose of which is to confirm whether the distribution state of the clothes meets the eccentric limit requirements of dehydration.

[0170] This method of controlling the drum speed in stages can achieve refined management of clothing distribution, reduce imbalance problems caused by uneven clothing distribution, improve dehydration efficiency while reducing noise and vibration, and enhance the user experience of the washing machine.

[0171] The speed of the acceleration phase a is preferably increased from 0 to 45 rpm, and the optimal operation time of the acceleration is greater than 2 seconds and less than or equal to 6 seconds (this time includes the time of acceleration and maintaining at 45 rpm). Accelerate to 45 rpm at a first fixed acceleration;

[0172] The second speed-up stage b is the clothing status identification stage, which increases the speed at a second fixed acceleration. The speed is preferably increased 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; in stage b, the load eccentricity value is identified while maintaining the speed (such as 93 rpm).

[0173] If the identified load eccentricity is less than the maximum limit for that stage, the speed will continue to increase to the next speed identification stage, with the maximum speed preferably being 120 rpm, 150 rpm, or 180 rpm, but not limited to these three speed settings. The identification speed for the next stage is not shown in the figure to further confirm the load eccentricity.

[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 speed 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, etc. The optimal recognition time for clothing eccentricity in each adjacent sub-stage is less than or equal to 5 seconds.

[0176] When running into this stage for the first time, the first stage of eccentricity identification is executed. If the limit is met, the second stage of eccentricity confirmation is carried out. In 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. The smallest eccentricity value detected in the previous few times determines the second fixed acceleration.

[0177] During stage b.1 of the identification process, an optimal range of eccentricity values ​​is set. If the values ​​do not meet this range, the speed is reduced to the starting speed of the next state distribution. This range varies depending on the dynamic balancing system of the entire machine structure. Once the machine structure is determined, a fixed set range (maximum eccentricity allowed without impacting the drum) is established. Values ​​within this range also represent the eccentricity of the clothing.

[0178] When increasing the speed 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 range: The acceleration is set between 8 rpm / s and 15 rpm / s (including the boundary value). This means that in this stage, the increase in acceleration is relatively gentle, which is suitable for leveling loads with a large load or a large area.

[0180] Second acceleration range: The acceleration is set between 35 rpm / s and 45 rpm / s (also inclusive). This indicates that during this acceleration phase, the acceleration is significantly increased, meaning the speed increases faster. This is particularly useful for absorbent loads, quickly bringing the load to the target speed for evenly distributed clothing.

[0181] The third acceleration range: The acceleration is adjusted to between 18 rpm / s and 25 rpm / s (inclusive of the boundary values). This means that in the third stage, the acceleration is between the first two ranges, which is used to compensate for the uneven distribution of clothes in the first two stages.

[0182] By setting these different acceleration intervals and strategically adjusting the acceleration intervals, the acceleration process can be finely controlled to meet the needs of different clothing distribution.

[0183] In the three major stages, in the first cycle, the first stage preferably uses the acceleration acceleration of the above-mentioned first acceleration interval, the second stage preferably uses the acceleration acceleration of the above-mentioned second acceleration interval, and the third stage preferably uses the acceleration acceleration of the above-mentioned third acceleration interval; after entering the second cycle, the second fixed acceleration preferably runs 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 in sequence according to 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 of the speed maintenance time in stage b is 0 to 5 seconds.

[0185] The rule for determining the second fixed acceleration is that if, after three consecutive cycles, the eccentricity states detected in the speed identification stage b do not meet the eccentricity state of speed increase and dehydration, the eccentricity state values ​​of stage b within the above three cycles are counted, and the acceleration with the highest frequency of smaller values ​​in the eccentricity state is determined to confirm which acceleration range the acceleration is in. Before this process, each acceleration is within the three ranges mentioned above, and each parameter is selected as the acceleration setting value for the interval. If the smaller values ​​of the eccentricity states of the three stages are concentrated in one acceleration interval, then the subsequent acceleration is within this interval, and the three values ​​are selected as the latest three acceleration control parameters. The selection rules are as follows:

[0186] For the second fixed acceleration adjustment during the process of speed a increasing to speed b, there is a detailed method to optimize the rate of speed increase to the spin 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 an acceleration within a range: When setting the acceleration, prioritize the upper and lower bounds of the range (Amax and Amin), as well as the median value (Amed). The principle is to prioritize one of these three values ​​and try them out to find the optimal acceleration.

[0189] 3. Speed-up status monitoring: If the washing machine fails to reach the required spin speed within three consecutive cycles at a given acceleration, the system will identify and record the frequency of small eccentric acceleration values. This helps determine whether the current acceleration value may be causing speed-up difficulties.

[0190] 4. Adjust the acceleration range: Based on the acceleration values ​​of the smaller eccentricity values ​​that appear more frequently 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 spin process again.

[0191] 5. Reset acceleration parameters: Based on the new range, follow the maximum, minimum, and median rules mentioned above to reset the acceleration parameters. The system will try to increase the speed to the spin speed again. If it still cannot reach the target, it will repeat the adjustment until the three acceleration settings are the same or the preset maximum time is reached.

[0192] This method uses monitoring and adjustment to find the optimal parameters that ensure effective dehydration without causing excessive wear or failure due to improper acceleration. Throughout the process, logical judgment and parameter adjustment cycles are repeated until the optimal acceleration setting is found.

[0193] The first, second and third intervals of the second fixed acceleration confirmed for the first time are used as default parameter intervals. After finding the optimal state distribution acceleration, it does not affect the next dehydration in the current washing process. The acceleration for the next dehydration needs to be reset.

[0194] The above process is to quickly find the speed, time, and acceleration parameters that are suitable for the optimal state of dehydrating clothes.

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

[0196] If it does not reach 50% of the programmed time, the current operation process will continue.

[0197] Before entering the load state adjustment stage, the eccentricity threshold of the eccentricity recognition state in the speed stage b is increased, and the threshold of the maximum eccentricity state value in the ab stage of the speed increase process is increased to d. When it is judged that the current eccentricity value meets the set threshold, the load adjustment stage is entered. If it does not meet the set threshold, the dehydration process is terminated.

[0198] During each of the three-stage cyclic dehydration process, the spin speed corresponding to step d and the duration of that speed are different. The maximum threshold increases to 60% of the limit state of speed b, which does not cause complete machine failure. The corresponding speed, duration, and number of repetitions are determined by threshold d. If the spin speed corresponding to the threshold is repeated at least twice, and the third time meets the same threshold as the previous two times, the load adjustment stage is considered to have ended, and dehydration ends. If the third time is different from the previous two times, the load adjustment process continues, or dehydration continues if the threshold for normal dehydration is met.

[0199] During the three-stage cyclic dehydration process, if the identified load eccentricity value is less than the maximum limit of this stage, the speed will continue to increase to the next speed identification stage, and its maximum speed is preferably 120 rpm, 150 rpm, and 180 rpm. The rule for determining its maximum speed is that the target speed reached by the newly added speed greater than the speed of 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 will continue to increase until the threshold is reached (the change in the eccentricity value is less than the change threshold, then the speed will increase). During the continuous operation of the speed, if the state change is greater than the threshold, the maintenance state will end and the speed will be reduced to a speed less than the threshold. If the state change gradually becomes less than the threshold, the speed will continue to increase to the speed of the state change threshold. After the set maintenance is completed, the state change and the threshold have not changed (proving that the eccentricity value has not changed), it means that the load state adjustment has been completed within the threshold range. The machine will then go through stage b again to identify the change in speed (reducing the speed to 93 rpm). If the change matches the normal speed increase, the machine will increase the speed directly. If it still does not match the normal speed increase, the machine will enter the load adjustment stage again. The maximum number of attempts in the load adjustment stage is set, and this number is determined by the different laundry load types and different laundry program modes.

[0200] In summary, the present invention mainly solves the problem of slow dehydration and high moisture content of the drum washing machine. By selecting the acceleration in the ab stage as a leveling parameter for rapid adjustment, the optimal parameters for adapting to the load are adjusted. By adjusting the moisture content of the load in the speed identification stage, the moisture content of the load is adjusted within a certain range, thereby improving the dehydration success rate and dehydration speed, and reducing the dehydration moisture content of the load.
