Description

Technical Field

[0001] This application relates to the field of fabric processing equipment technology, and in particular to a washing control method, electronic equipment, and fabric processing equipment. Background Technology

[0002] With the improvement of people's living standards, washing machines have become one of the essential household appliances. In the development of washing machines, improving washing performance, reducing energy consumption, and minimizing damage to fabrics have always been key research directions. In particular, front-loading washing machines, due to their gentle washing methods and minimal damage to fabrics, are increasingly favored by consumers.

[0003] Currently, fabric handling equipment on the market, especially drum washing machines, typically use a preset fixed spin speed for control during the washing process. While this control method is simple and easy to implement, it cannot dynamically adjust according to changes in the fabric's condition during the actual washing process, resulting in less than ideal washing results. Existing technologies include some research and applications regarding washing machine spin speed control.

[0004] However, the aforementioned existing technologies have the following shortcomings:

[0005] First, most existing washing machine spin control methods use a preset fixed spin speed or determine the spin speed based on the initial detected fabric condition, lacking the ability to dynamically adjust the spin speed according to the real-time condition of the fabric during the washing process. This means that when the fabric condition changes during the washing process (such as fabric distribution, water absorption, etc.), the spin speed cannot be adjusted in time to adapt to these changes, affecting the washing effect.

[0006] Secondly, while existing technologies include methods for adjusting the rotation speed based on parameters such as fabric weight and material, they lack a mechanism for continuous monitoring and evaluation of rotation speed stability. In actual washing processes, due to factors such as uneven fabric distribution and uneven water absorption, even with a suitable rotation speed set, rotation speed instability may occur, affecting washing performance and equipment operational stability.

[0007] Third, existing technologies typically adjust spin speed in a single cycle or in stages, lacking a periodic and continuous spin speed optimization mechanism. This prevents the washing machine from continuously optimizing based on the dynamic changes in the fabric's condition throughout the washing process, making it difficult to achieve optimal washing results.

[0008] Fourth, existing technologies lack effective methods for evaluating rotational speed stability and rotational speed adjustment strategies based on evaluation results, making it impossible to achieve precise control and optimization of rotational speed. This results in low washing efficiency, energy waste, and may cause unnecessary damage to fabrics. Summary of the Invention

[0009] In view of this, this application provides a washing control method, electronic device and fabric handling device to solve the problem that poor washing effect of existing drum washing machines leads to a poor user experience.

[0010] A first aspect of this application provides a washing control method applied to a fabric treatment device, the fabric treatment device including a fabric treatment drum, the fabric treatment drum being controlled to run a washing program, the washing control method comprising:

[0013] The first stage of speed processing includes speed adjustment or speed maintenance, and the second stage is used to determine speed stability;

[0014] The speed processing action in the first stage of the subsequent speed processing cycle is determined based on the stability judgment result of the previous speed processing cycle in the second stage.

[0015] In some embodiments, the speed processing action in the first stage of the subsequent speed processing cycle is determined based on the stability judgment result of the prior speed processing cycle in the second stage, including:

[0016] If the judgment result in the second stage is stable, the fabric processing cylinder is controlled to maintain the rotation speed in the first stage of the subsequent rotation speed processing cycle;

[0017] If the judgment result in the second stage is unstable, the speed adjustment of the fabric processing cylinder is controlled in the first stage of the subsequent speed processing cycle.

[0018] In some implementations, the duration of the second stage is longer than the duration of the first stage.

[0019] In some embodiments, the periodic rotation speed optimization process during washing includes:

[0025] In some embodiments, the dynamic monitoring of the change in the rotational speed difference of the fabric treatment drum within the number of revolutions in the second stage to determine the optimal washing speed of the fabric treatment drum includes:

[0026] Determine the speed difference of the fabric treatment cylinder in each revolution during the second stage to determine the average speed difference;

[0027] Based on the relationship between the average speed difference and the preset speed difference threshold, the optimal washing speed of the fabric treatment drum in the subsequent speed treatment cycle is determined.

[0028] In some embodiments, determining the optimized washing speed of the fabric treatment drum in a subsequent rotational speed treatment cycle based on the relationship between the average rotational speed difference and a preset rotational speed difference threshold includes:

[0029] If the average speed difference is less than or greater than the preset speed difference threshold, the target speed is increased or decreased based on the current speed of the fabric processing cylinder to perform the speed adjustment.

[0030] If the average speed difference is equal to the preset speed difference threshold, the current speed of the fabric processing tube is maintained to perform the speed maintenance.

[0031] In some implementations, the set number of revolutions is at least three revolutions;

[0032] The number of laps in the first stage is the first lap of the set number of laps;

[0033] The number of laps in the second stage is the number of laps other than the first lap in the set number of laps.

[0034] In some embodiments, controlling the fabric treatment drum to operate at the optimized washing speed for a set number of revolutions in a subsequent speed treatment cycle includes:

[0035] During both the forward and reverse rotation of the fabric processing cylinder, the rotation speed of the fabric processing cylinder is adjusted periodically by performing rotation speed optimization processing.

[0036] In some embodiments, the fabric treatment drum is used to wash the fabric;

[0037] The step of obtaining the initial washing speed of the fabric treatment drum at the beginning of the washing process includes:

[0038] In the initial stage of the washing process, the load state parameters of the fabric are acquired;

[0039] The load state parameters are input into a preset mapping model to determine the initial washing speed and execution time, wherein the execution time is the time during which the fabric treatment drum runs at the initial washing speed.

[0040] In some embodiments, the load state parameters include fabric parameters and washing parameters of the fabric, wherein the fabric parameters include at least the fabric weight, and the washing parameters include at least the washing water level and the washing water volume;

[0041] as well as,

[0042] The preset mapping relationship model is a membership model based on standard load calibration, which establishes the mapping relationship between the weight grade, water level grade and water volume grade of the fabric and the rotation speed grade and time grade.

[0043] A second aspect of this application provides an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the washing control method as described in the first aspect.

This application dynamically adjusts the washing speed of the fabric processing drum, ensuring uniform fabric distribution within the drum, reducing tangling and accumulation, and significantly improving the washing effect. Simultaneously, it optimizes the fabric distribution during the washing stage, providing a better foundation for the subsequent spin-drying stage, improving the uniformity of centrifugal force distribution, increasing spin-drying efficiency, reducing vibration and noise during spin-drying, and improving the user experience; by dynamically adjusting the speed, it avoids excessive mechanical stress caused by uneven fabric distribution, extending the washing machine's lifespan while reducing energy waste.

[0056] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, but should not be construed as limiting this application.

[0057] Example 1

[0058] like Figures 1 to 2 As shown, this embodiment provides a washing control method applied to a fabric processing device. The fabric processing device includes a fabric processing drum, which is controlled to run a washing program. The washing control method can be applied to the fabric processing device. The fabric processing device includes a fabric processing drum, which is capable of washing fabrics; that is, it is used to wash the fabrics within its respective drum in a washing mode. The washing mode refers to the process of injecting a certain amount of water and detergent into the fabric processing drum and cleaning the fabrics through the rotation of the drum.

[0059] The fabric processing equipment may include, but is not limited to, washing machines, which may include, but are not limited to, washer-dryer combos, etc. For example, the washing machine may be a front-loading washing machine or a top-loading washing machine with drying or washing functions, and of course, it may also be other types of fully automatic washing machines.

[0060] The washing control method includes the following steps:

[0061] Step S100: During the washing process, the rotation speed is periodically optimized.

[0062] Step S200: The speed optimization processing corresponds to the speed processing cycle, including a first stage and a second stage; the speed processing action in the first stage includes speed adjustment or speed maintenance, and the second stage is used to judge speed stability; wherein, the speed processing action in the first stage of the subsequent speed processing cycle is determined based on the stability judgment result of the second stage of the preceding speed processing cycle.

[0063] Specifically, the speed processing action in the first stage of the subsequent speed processing cycle is determined based on the stability judgment result of the second stage of the preceding speed processing cycle. This includes: if the judgment result in the second stage is stable, it means that the washing speed of the fabric processing drum is within the preset speed range and meets the speed control requirements of the current washing mode. In this case, the fabric processing drum can maintain its speed in the first stage of the subsequent speed processing cycle. If the judgment result in the second stage is unstable, it means that the washing speed of the fabric processing drum is not within the preset speed range and does not meet the speed control requirements of the current washing mode. In this case, the fabric processing drum will adjust its speed in the first stage of the subsequent speed processing cycle.

[0064] In this embodiment, the duration of the second stage is longer than that of the first stage. For example, during one rotational speed processing cycle, the fabric processing cylinder rotates once in the first stage, and twice or more in the second stage. It should be noted that the number of rotations of the fabric processing cylinder here does not refer to one complete rotation of the cylinder itself, but rather the number of rotations within a set cycle or a set time period. This design ensures sufficient time for accurate assessment of rotational speed stability, thus providing a reliable basis for adjusting or maintaining the rotational speed during the first stage.

[0065] During the washing process, the rotation speed is periodically optimized, specifically by obtaining the initial washing speed of the fabric treatment drum at the beginning of the washing program.

[0066] The fabric treatment drum is controlled to run a set number of revolutions based on the initial washing speed. The set number of revolutions includes the number of revolutions in the first stage and the number of revolutions in the second stage.

[0067] The change in the rotation speed difference of the fabric treatment drum during the second stage is dynamically monitored to determine the optimal washing speed of the fabric treatment drum.

[0068] The fabric treatment drum is controlled to run at a set number of rotations in subsequent speed treatment cycles to optimize the washing speed.

[0069] In this embodiment, the fabric treatment drum undergoes at least two iterations of speed optimization. By continuously monitoring the subsequent speed changes of the fabric treatment drum through multiple iterations, the speed control of the fabric treatment drum can be kept within the set speed range, improving the stability of the fabric treatment drum's operation and thus enhancing the washing effect.

[0070] In one example, the change in the rotation speed difference of the fabric treatment drum within a certain number of revolutions in the second stage is dynamically monitored to determine the optimal washing speed of the fabric treatment drum. Specifically, this includes: determining the rotation speed difference of the fabric treatment drum within each number of revolutions in the second stage to determine the average rotation speed difference; and determining the optimal washing speed of the fabric treatment drum in subsequent rotation speed processing cycles based on the relationship between the average rotation speed difference and a preset rotation speed difference threshold.

[0071] Specifically, based on the relationship between the average speed difference and the preset speed difference threshold, the optimized washing speed of the fabric treatment drum in the subsequent speed treatment cycle is determined. This includes: if the average speed difference is less than the preset speed difference threshold, the target speed is increased based on the current speed of the fabric treatment drum to adjust the speed.

[0072] After determining the initial washing speed, the fabric handling equipment will be run for at least three revolutions, with particular attention paid to the actual speed data during the second and third revolutions. The speeds of these two revolutions will be recorded, and the difference between them will be calculated, with the average value used as a reference.

[0073] Based on this, the stability of the fabric processing drum's rotational speed can be captured, because the average value of the rotational speed difference can reflect whether the fabric processing equipment is operating smoothly under the current load. If the average rotational speed difference is too large or too small, the current rotational speed of the fabric processing drum needs to be adjusted to better adapt to the distribution of fabric and washing water within the drum.

[0074] Next, the calculated average speed difference is compared with a preset speed difference threshold. If the average value is found to be less than the preset speed difference threshold, it means that the current speed is not achieving the desired tumbling effect. In this case, the fabric processing cylinder's control system can be used to increase the speed increment by a preset value, for example, by 5 revolutions based on the current speed.

[0075] For example, in some light-load scenarios, the initial washing speed may be too low, resulting in insufficient tumbling of the fabric. Increasing the speed can enhance the cleaning effect. The advantage of this adjustment method is that it gradually approaches the optimal operating state, avoiding excessive burden on the fabric handling drum equipment due to a one-time excessive speed adjustment.

[0076] If the average value is found to be greater than the preset speed difference threshold, it indicates that the current speed is too high, and the fabric inside the drum is prone to tangling or piling. In this case, the control system of the fabric processing drum can be used to reduce the speed increment of the fabric processing drum by a preset amount, for example, by 5 revolutions from the current speed.

[0077] Furthermore, after each speed adjustment, the speed changes during subsequent operation will be continuously monitored, and the average value of the adjusted speed difference will be compared with the preset speed difference threshold. Incremental adjustments will be performed cyclically until the average speed difference meets the speed control requirements of the current washing mode.

[0078] For example, when the fabric is heavy and the water level is high, it may be necessary to make several small adjustments to the rotation speed to ensure that the fabric is evenly distributed inside the drum, while avoiding excessive vibration of the fabric handling drum equipment due to excessively high rotation speed. This continuous adjustment mechanism can dynamically adapt to different washing scenarios, ensuring cleaning effect while protecting the stability of the fabric handling drum equipment operation.

[0079] It should be noted that each of the above steps is closely linked, forming a complete closed-loop control process from determining the initial washing speed to implementing dynamic adjustments.

[0080] For example, based on the initial washing speed setting, potential imbalances can be identified by calculating and comparing the average speed difference. Subsequent cyclic adjustments can then specifically address these issues, ultimately achieving a good match between the current speed of the fabric handling drum and the load within the drum. This not only improves washing efficiency but also effectively reduces noise and wear during the operation of the fabric handling drum equipment, providing users with a better experience.

[0081] like Figures 1 to 2 As shown in one example, if the average speed difference is equal to a preset speed difference threshold, the current speed of the fabric processing drum is maintained to maintain the speed.

[0082] The average speed difference of the fabric processing drum is obtained from the operating data. This average speed difference is compared with a preset speed difference threshold to determine if they are equal. If they are equal, the current speed value is extracted from the current operating parameters and kept constant. In the first phase of the subsequent speed optimization cycle, while maintaining the current speed value, the average speed difference data for each revolution is continuously monitored in the second phase of the subsequent speed optimization cycle. The new average speed difference data is again compared with the preset speed difference threshold. If the new average speed difference is still equal to the preset speed difference threshold, the current speed value is maintained to ensure the stability of speed control.

[0083] like Figures 1 to 2 As shown in one example, the washing speed is adjusted based on the relationship between the average speed difference and the preset speed difference threshold. Specifically, if the average speed difference is greater than the preset speed difference threshold, the target speed is reduced based on the current speed of the fabric treatment drum. The target speed can be 5 revolutions or other values, which are not specifically limited here.

[0084] The average speed difference data of the fabric treatment drum is obtained from the operational data and compared with a preset speed difference threshold to determine whether the current speed of the fabric treatment drum needs to be adjusted. If the average speed difference is greater than the preset speed difference threshold, a reduction operation is performed on the current speed, reducing it by a preset reduction value (e.g., 5 revolutions to the target speed) to form the adjusted optimized washing speed. The adjusted optimized washing speed is applied to the control process, and the speed change of the fabric treatment drum in each revolution during the second stage of the subsequent speed optimization cycle is monitored in real time to ensure that the speed adjustment meets the expected range. During the speed change process, new average speed difference data is continuously collected and compared with the preset speed difference threshold again to further correct the adjusted target speed.

[0085] like Figure 1 and Figure 2 As shown, in some embodiments, the set number of laps is at least three laps. The first stage consists of the first lap of the set number of laps. The second stage consists of the remaining laps of the set number of laps excluding the first lap.

[0086] The process of determining the rotational speed difference of the fabric treatment cylinder within the target number of revolutions, and then determining the average value of the rotational speed difference, includes: determining the rotational speed difference of the fabric treatment cylinder in each revolution number excluding the first revolution; and determining the average value of the rotational speed difference based on each rotational speed difference.

[0087] In this example, the data from the first revolution of the fabric treatment cylinder were not used because the rotational speed of the fabric treatment cylinder in the first revolution may be unstable, resulting in a large difference in rotational speed, which would affect the accuracy of the subsequent determination of the average value of the rotational speed difference. In other words, excluding the data from the first revolution can improve the accuracy of subsequent calculations.

[0088] like Figure 1 and Figure 2 As shown, in some embodiments, the process of controlling the fabric treatment drum to run a set number of revolutions in subsequent speed treatment cycles to optimize washing speed includes:

[0089] During both the forward and reverse rotation of the fabric treatment drum, the rotation speed is adjusted periodically using the method described in any of the above embodiments. Based on this, the current rotation speed of the fabric treatment drum can meet the rotation speed control requirements of the current washing mode during both forward and reverse rotation, thereby ensuring optimal washing results in different rotation directions.

[0090] like Figures 1 to 2 As shown, in some embodiments, a fabric treatment drum is used to wash the fabric. The step of obtaining the initial washing speed of the fabric treatment drum at the beginning of the washing process includes:

[0091] At the beginning of the washing program, the load state parameters of the fabric are acquired. The load state parameters are input into a preset mapping model to determine the initial washing speed and execution time, where the execution time is the time the fabric treatment drum runs at the initial washing speed.

[0092] It should be noted that the execution time refers to the running time during which the control system of the fabric handling equipment drives the fabric handling drum to operate. This can be achieved using existing technology, which will not be elaborated upon here. In one example, the execution time can be the process of the fabric handling drum running a complete sine or cosine cycle at the initial washing speed.

[0093] The load status parameters include fabric parameters and washing parameters. Fabric parameters include at least the fabric weight, and washing parameters include at least the washing water level and washing water volume. The fabric weight is determined before water intake, obtained through a motor sensor. The washing water level is the currently set washing water level, and the washing water volume is the amount of water required to reach the user-set washing water level.

[0094] In the preparation phase before the washing program starts, the process of obtaining the fabric weight through the motor sensing system can be understood as a load-feedback-based detection method. The motor's operating characteristics differ under no-load and load conditions. Specifically, when the motor starts, it generates different current or speed feedback signals based on the resistance generated by the fabric weight. By analyzing these signals, the fabric weight can be accurately calculated. This provides the basic data for subsequent washing parameter settings, ensuring the washing process better matches actual needs. Simultaneously, recording the user-set water level and water volume data helps determine if the washing environment matches the fabric weight, thus avoiding resource waste or insufficient washing.

[0095] The preset mapping model is a membership model based on standard load calibration, used to establish the mapping relationship between fabric weight class, water level class, water volume class and speed class and time class. The membership model is a rule-based model that sets the optimal washing speed and execution time according to standard fabric weight, water level, and water volume, setting the maximum tumbling speed and execution time based on fabric weight class, water level class, and water volume. See Tables 1 to 4 below for details:

[0096]

[0097] Table 1

[0098]

[0099] Table 2

[0100]

[0101] Table 3

[0102]

[0103] Table 4

[0104] Tables 1 to 4 above categorize fabrics by weight: 1 to n. Each fabric weight corresponds to a different water volume, and each water volume corresponds to the water level, washing speed, and execution time under the current condition. For example, if the fabric weight is in Table 1, the user sets the water level before the program starts. After the program starts, it calculates the water volume required to reach the set water level. The water volume required to reach the set water level, along with the fabric weight and water level, is then input into the membership model to obtain the washing speed and execution time that meet the specified conditions.

[0105] It should be noted that Tables 1 to 4 above represent the optimal parameters for each stage of the current operation.

[0106] In other words, inputting the obtained fabric weight, washing water level, and washing water volume data into the pre-established membership model can be viewed as a rule-based matching process. The membership model is a pre-defined rule base that, based on extensive experimental data, divides fabric weight, washing water level, and washing water volume into different level ranges and matches each combination with an initial washing speed and execution time. This design allows the washing equipment to quickly find a relatively reasonable starting parameter under different load conditions, reducing the time spent on blind adjustments and thus improving efficiency.

[0107] like Figures 1 to 2 As shown in a specific example, before the washing program starts, the weight of the fabric is obtained through the motor sensing system, and the water level set by the user and the water volume data when the set water level is reached during the water intake process are recorded to form an initial parameter set.

[0108] The initial parameter set is input into a pre-established membership model. Based on the fabric weight class, water level, and water intake volume, the initial washing speed and corresponding execution time parameters are determined. According to the determined initial washing speed, the fabric treatment drum is controlled to run at least three revolutions. The speed difference between the second and third revolutions is obtained, its average value is calculated, and compared with a preset speed difference threshold. If the average speed difference is less than the preset threshold, the current speed of the fabric treatment drum is increased by a fixed increment, such as the target speed, and speed control is re-executed. In subsequent cycles of the fabric treatment drum, the average speed difference for the second, third, or fourth revolutions (or similar) is repeatedly obtained. Through the above control rules, the speed is continuously adjusted so that the average speed difference meets the speed control requirements of the current washing mode.

[0109] Furthermore, if the average speed difference is less than the preset speed difference threshold, the current speed of the fabric processing drum is adjusted and controlled by increasing the target speed. Conversely, if the average speed difference is greater than the preset speed difference threshold, the current speed of the fabric processing drum is adjusted and controlled by decreasing the target speed. Both of these processes can be understood as a gradual optimization process. After each adjustment, the speed difference is re-acquired and compared, allowing the fabric processing equipment to gradually approach the ideal operating state. This avoids the instability risks that may arise from excessively large adjustment ranges. Simultaneously, through multiple iterations, it ensures that the parameter control requirements of the washing process are ultimately met, guaranteeing the subsequent washing effect.

[0110] For example, when calculating and fine-tuning the speed difference for each rotation, if the fabric handling equipment detects that the average speed difference between the second and third rotations is lower than a preset speed difference threshold, it means that the current speed of the fabric handling drum is insufficient to achieve the ideal tumbling effect. In this case, the fabric handling equipment will automatically increase the current speed slightly to compensate for the difference. This allows for real-time response to changes in the operating status of the fabric handling drum under the current washing mode, ensuring that the washing effect remains at an optimal level while avoiding fabric damage or incomplete cleaning caused by excessively high or low speeds. Through the coordination of these multiple aspects, the entire control process forms a closed loop, from data acquisition to parameter matching and operational adjustment, each step is interconnected, ensuring precise control of the washing speed and execution time.

[0111] In one possible implementation, the fabric handling equipment determines the initial washing speed and execution time based on fabric weight and water level information (washing water level and washing water flow). Assuming the fabric is lightweight and the water level is set to low, the membership model outputs an initial washing speed of 80 revolutions per minute.

[0112] After the fabric treatment drum is started, it is controlled to complete at least three rotations. Due to changes in the weight of the fabric inside the drum and the distribution of the washing water, the drum may not operate at the initial washing speed output by the membership model. In other words, the drum's rotation speed will differ from the initial washing speed during each rotation, resulting in speed variations within that rotation. Sensors record the drum's rotation speed in real time for each rotation; for example, the first rotation is 78 rpm, the second is 82 rpm, and the third is 80 rpm. This recording method ensures the accuracy of subsequent speed difference calculations and helps to accurately assess the stability of the drum operation.

[0113] Specifically, for the recorded rotational speed data, the difference in rotational speed for each of the remaining revolutions excluding the first revolution is calculated.

[0114] For example, the speed difference of the second fabric treatment drum is 82-80=2 revolutions, while the speed difference of the third fabric treatment drum is zero. Calculating the average of these speed differences, i.e., (2+0) / 2=1 revolution, yields an average speed difference of 1. This process quantifies the speed fluctuations, providing a data basis for subsequent adjustments, ensuring the smooth operation of the drum during washing, thereby improving the fabric tumbling effect.

[0115] In one embodiment, the calculated average speed difference is compared with a preset speed difference threshold. Assuming the preset speed difference threshold is 3, and the current average speed difference is 1 (less than the preset threshold), it indicates that the current speed fluctuation of the fabric treatment drum is small, potentially leading to insufficient fabric tumbling. In this case, the fabric treatment equipment's control system automatically increases the speed of the fabric treatment drum, for example, by 5 revolutions per minute. This adjustment gradually enhances the tumbling force of the fabric treatment drum, optimizing the washing effect while avoiding mechanical vibration caused by excessive speed fluctuations.

[0116] Understandably, after adjusting the engine speed, the engine speed data for subsequent revolutions should continue to be monitored.

[0117] For example, the average speed difference between the two rotations excluding the fourth rotation in the fourth, fifth, and sixth rotations is recalculated, and the above process is repeated to ensure that the rotation speed is dynamically adjusted to meet washing requirements. This continuous monitoring and adjustment mechanism maintains the stability of drum operation, providing a basis for uniform fabric distribution in the subsequent spin-drying stage, thereby reducing noise and vibration and improving overall washing efficiency.

[0118] It should be noted that the end of the fabric treatment drum rotation process is marked by the control time set for the current washing stage. When the control time is reached, the control direction of the fabric treatment drum is switched. In the opposite direction, the same speed control rules as described above are used for speed control.

[0119] Example 2

[0120] This embodiment provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the washing control method as described in Embodiment 1.

[0121] The electronic device can be a control unit of the fabric processing equipment, used to control the operation of the fabric processing cylinder. The memory can be a read-only memory, random access memory, flash memory, hard disk, or other type of storage medium. The processor can be a central processing unit, microprocessor, or other type of processor.

[0122] The computer program contains instructions for executing a washing control method. When the processor executes these instructions, it can perform periodic speed optimization during the washing process, including control of the first and second stages, and dynamic adjustment of the speed of the fabric treatment drum in the first stage based on the judgment result of the second stage.

[0123] Example 3

[0124] This embodiment provides a fabric treatment device that is controlled by the washing control method described in Embodiment 1, or includes the electronic equipment described in Embodiment 2.

[0125] The fabric processing equipment can be a washing machine, dryer, or washer-dryer combo, or any other device capable of processing fabrics. The equipment includes a fabric processing drum that rotates under the drive of a motor to perform washing, rinsing, and dehydration processes on the fabrics.

[0126] By adopting the washing control method of the present invention, the fabric treatment equipment can periodically optimize the rotation speed during the washing process, dynamically adjust the rotation speed of the fabric treatment drum according to the load state of the fabric, improve the washing effect, reduce energy consumption, and extend the service life of the equipment.

[0127] It should be noted that Examples 1, 2, and 3 are all types of washing control methods.

[0128] In the above example scheme, the washing process of the fabric treatment equipment is controlled by the following method: the washing control method includes: periodically performing speed optimization processing during the washing process; the speed optimization processing corresponds to a speed processing cycle, including a first stage and a second stage; the speed processing action in the first stage includes speed adjustment or speed maintenance, and the second stage is used to judge speed stability; wherein, the speed processing action in the first stage of the subsequent speed processing cycle is determined based on the stability judgment result of the second stage of the previous speed processing cycle.

[0129] In this example, during the washing stage, the levels determined by the membership model in the washing process provide a more precise control range for the rotation speed and acceleration parameters during the dehydration stage. Different levels correspond to different fabric distribution states, thus presetting the optimal range of dehydration rotation speed and acceleration parameters. This control method not only ensures the tumbling effect of the fabric during washing but also dynamically adjusts the washing speed to ensure uniform fabric distribution within the drum, reducing tangling and piling, avoiding excessive mechanical stress caused by uneven fabric distribution, reducing energy waste, and significantly improving the washing effect.

[0130] At the same time, it can optimize the fabric distribution during the washing stage and enable the fabric to be quickly and evenly distributed in the subsequent dehydration stage, thereby improving dehydration efficiency, reducing noise and vibration during the dehydration process, and improving the user experience.
