[0002] Traditional washing machines are controlled by preset parameters during operation to ensure that clothes fall into the optimal position of the drum during the washing process. However, due to the different materials, weights and moisture contents of clothes, the preset parameters are usually difficult to ensure that the clothes are fully beaten during actual operation, resulting in reduced washing efficiency, increased time to complete the washing process, and reduced user experience.

[0003] In response to the above shortcomings, the prior art proposes, on the one hand, determining the falling area and movement state of the clothes based on the movement information in the washing machine drum, and adjusting the washing parameters according to the falling area and movement state; on the other hand, it proposes weighing the clothes before washing, and determining the washing speed corresponding to the clothes according to the weight of the clothes.

[0004] However, the above technical means still rely on the initial state and initial distribution of the clothes. There are still limitations in the real-time optimization of the weight changes caused by water absorption and dehydration of the clothes during the washing process, and the further changes in the tumbling effect. It is not applicable to the control parameters caused by changes in the state of the clothes themselves, and there is a lack of good solutions. Summary of the Invention

[0010] Optionally, after monitoring the output power of the washing machine motor and drawing an image based on the output power to obtain the second curve, the method also includes: when the difference between the maximum and minimum values of the first curve is less than a third threshold and the difference between the maximum and minimum values of the second curve is greater than a fourth threshold, reducing the set speed by a first preset step size and redrawing the first curve and the second curve; when the difference between the maximum and minimum values of the first curve is less than the third threshold and the difference between the maximum and minimum values of the second curve is less than the fourth threshold, increasing the set speed by a first preset step size and redrawing the first curve and the second curve; when the number of repeated drawing times reaches a fifth threshold and the fluctuation duration cannot be recorded, controlling the washing machine to operate at a preset speed.

[0026] As introduced in the background technology, the existing technology still relies on the initial state and initial distribution of the clothes. There are still limitations in the real-time optimization of the weight changes caused by water absorption and dehydration of the clothes during the washing process, and the further changes in the tumbling effect. The control parameters caused by the changes in the state of the clothes themselves are not applicable, and there is a lack of good solutions. In order to solve the problem in the existing technology that due to the dynamic changes in the water content of the clothes in different washing stages, it is difficult to ensure that the clothes are fully tumbled by controlling according to preset parameters, resulting in a decrease in washing efficiency, the embodiments of the present application provide a tumbling control method, a tumbling control device, a computer-readable storage medium and a washing machine.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 This is a hardware structure block diagram of a mobile terminal for a method for controlling the falling of a washing machine according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1Only one is shown) a processor 102 (the processor 102 may include but is not limited to a microprocessor MCU or a programmable logic device FPGA and other processing devices) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input and output device 108 for communication functions.

In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0030] In this embodiment, a method for controlling the pounding of a washing machine running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] Figure 2 FIG. 1 is a flow chart of a method for controlling the falling of a washing machine according to an embodiment of the present application. Figure 2 As shown, the method includes the following steps:

[0032] Step S201, controlling the washing machine to run at a set speed for one rotation cycle, and recording the time it takes for the eccentricity value of the drum of the washing machine to change from a maximum value to a preset eccentricity value during the rotation cycle to obtain a fluctuation duration;

[0033] Specifically, the eccentricity value refers to the imbalance caused by uneven distribution of clothes during the rotation of the drum, which is used to reflect the distribution of clothes inside the drum. Specifically, the process of the eccentricity value intercepted in this application from the maximum value to the preset eccentricity value is actually the process of clothes from detachment to falling. The longer the process is, the better the beating effect of the washing process.

[0034] As you can understand, the eccentricity is the distance from the center of the drum to the center of gravity of the clothing, and it changes as the drum rotates. As the clothing is thrown from one wall to another within the drum, the eccentricity fluctuates from a maximum value to a preset value. The tumbling time is then used to characterize the tumbling efficiency, optimizing the drum speed for optimal washing results.

[0035] Step S202, adjusting the set speed to traverse the speed values of the washing machine, and recording the fluctuation duration corresponding to each speed value;

[0036] Specifically, the goal of this process is to fine-tune the speed and observe the effect on the duration of fluctuations, thereby dynamically optimizing the speed point that achieves the best results in terms of tumbling clothes. Through iterative adjustments, the optimal solution is gradually approached, ensuring that each adjustment has a positive impact.

[0037] It is understandable that since the change in fluctuation duration is linear, the optimization process continues until the current fluctuation duration is less than the fluctuation duration of the last monitoring, that is, continuing to adjust in the same direction will lead to further performance degradation.

[0038] Step S203: The set speed corresponding to the maximum fluctuation duration is determined as the target speed, and the washing machine is controlled to operate at the target speed.

[0039] Specifically, the target speed is the optimal speed found, which can maximize the beating efficiency of clothes while reducing unnecessary energy consumption and wear.

[0040] Through this embodiment, first, the washing machine is controlled to run a rotation cycle at a set speed, and the time it takes for the eccentricity value of the washing machine's drum to change from the maximum value to the preset eccentricity value during the rotation cycle is recorded to obtain the fluctuation time; then, the set speed is adjusted to traverse the speed values of the washing machine, and the fluctuation time corresponding to each speed value is recorded; finally, the set speed corresponding to the maximum fluctuation time is determined as the target speed, and the washing machine is controlled to run at the target speed. The present application is set to monitor the eccentricity value of the drum during the washing process, and optimize the speed of the washing machine according to the fluctuation time of the eccentricity value, so as to realize the dynamic adjustment of the control parameters of the washing machine as the state of the clothes changes, and ensure that the clothes can be fully beaten in each washing stage, so as to solve the problem in the prior art that due to the dynamic change of the water content of the clothes in different washing stages, it is difficult to ensure the sufficient beating of the clothes by controlling according to the preset parameters, resulting in a decrease in washing efficiency.

[0041] In order to adjust the rotation speed according to the actual detection state, in an optional embodiment, the above step S202 includes:

[0042] Step S2021: when the rotation cycle is the first rotation cycle and the fluctuation duration is 0, the set rotation speed is reduced by a first preset step length;

[0043] It is understandable that when the fluctuation duration of the eccentricity value is 0, it means that the clothes are not effectively beaten inside the drum. It is probably because the drum speed is too high, causing the clothes to always stick to the wall and no beating action occurs.

[0044] Therefore, when it is detected that the fluctuation duration is 0, the set speed is reduced by a fixed increment (the first preset step mentioned above), so that the clothes can fall freely at a specific position inside the drum, producing a falling action.

[0045] It should be noted that when the fluctuation duration is 0, there is also a situation where the speed is too low and the clothes are always at the bottom of the drum. However, in actual testing, the speed is almost never set too low, so it is not used as a reference.

[0046] Step S2022: When the rotation cycle is the first rotation cycle and the fluctuation duration is not 0, the set rotation speed is increased by a first preset step length.

[0047] Specifically, when it is monitored that the fluctuation duration is not 0, it means that the current rotation speed is able to make the clothes effectively threshed inside the drum. At this time, the set rotation speed is increased by the first preset step to check whether the fluctuation duration can be extended to improve the threshing efficiency of the clothes.

[0048] Through the above-described embodiment, the drum speed is dynamically adjusted, allowing the washing machine to intelligently find the optimal speed point, effectively flying and tumbling clothes within the drum, improving washing efficiency and ensuring that clothes are fully cleaned. Furthermore, control based on the optimal speed reduces unnecessary high-speed operation, reducing energy waste, and simultaneously reducing the occurrence of excessively low and high speeds, thereby reducing wear and tear on mechanical components.

[0049] In order to achieve dynamic adjustment of the drum speed, in an optional embodiment, the above step S202 further includes:

[0050] Step S2023: if the fluctuation duration of the current rotation cycle is greater than the fluctuation duration of the previous rotation cycle and the set speed of the current rotation cycle is greater than the set speed of the previous rotation cycle, increase the set speed by a first preset step size;

[0051] Specifically, if the fluctuation duration (T1) at the current speed (Xrpm+Δrpm) is greater than the fluctuation duration (T0) at the previous speed (Xrpm), it means that the higher speed enhances the beating efficiency of the clothes, and the system should continue to increase the speed (Xrpm+Δrpm→Xrpm+2Δrpm) to further explore higher efficiency points.

[0052] Step S2024: when the fluctuation duration of the current rotation cycle is greater than the fluctuation duration of the previous rotation cycle and the set speed of the current rotation cycle is less than the set speed of the previous rotation cycle, the set speed is reduced by a first preset step.

[0053] Specifically, if the fluctuation duration (T1) at the current speed (Xrpm-Δrpm) is greater than the fluctuation duration (T0) at the previous speed (Xrpm), this indicates that lowering the speed will help improve the throwing efficiency, and the system should continue to lower the speed (Xrpm-Δrpm→Xrpm-2Δrpm).

[0054] Through the above embodiment, by monitoring the fluctuation duration before and after adjustment and further comparing them, the rotation speed of the drum can be dynamically adjusted, which can significantly improve the working efficiency and energy-saving performance of the washing machine.

[0055] In order to intercept the above-mentioned fluctuation duration, in an optional implementation manner, the above-mentioned step S201 includes:

[0056] Step S2011, monitoring the eccentricity of the drum and plotting a curve showing the eccentricity changing over time to obtain a first curve;

[0057] Specifically, by drawing a change curve of the eccentricity value in real time, the change in the distribution state of the clothes in the drum can be intuitively reflected.

[0058] Step S2012: monitoring the output power of the motor of the washing machine and plotting a curve showing the output power changing over time to obtain a second curve;

[0059] Specifically, a curve of the change in the motor output power of the washing machine is drawn to reveal the low energy consumption during mixed rotation, reflecting the washing efficiency from another perspective.

[0060] Step S2013: If the time points corresponding to the maximum values of the first and second curves are the same, the time point corresponding to the maximum value is used as the starting time, and the time point when the eccentricity value decreases to a value less than a first threshold value as the ending time, and the fluctuation duration is recorded;

[0061] Specifically, when the time points corresponding to the maximum values of the first curve (eccentricity value) and the second curve (motor output power) are the same, this means that the increase in motor load coincides with the time when the beating action inside the drum occurs. The time point when the eccentricity value and the motor power decrease synchronously is intercepted, that is, the above-mentioned starting moment, until the eccentricity value returns to positive (returns to a stable state), that is, the above-mentioned end moment, and the above-mentioned fluctuation duration is obtained.

[0062] In step S2014, when the time points corresponding to the maximum values of the first curve and the second curve are different and the difference is less than the second threshold, the time point corresponding to the delayed maximum value is taken as the starting time, and the time point when the eccentricity value drops to a difference with the preset eccentricity value less than the first threshold is taken as the ending time, and the fluctuation duration is recorded.

[0063] Specifically, the maximum values of the first and second curves occur at different times, but this time difference is less than a second threshold (a small preset time window). This indicates that while the two are not completely synchronized, they can still produce an effective striking action. The fluctuation duration is determined by measuring the time at which the eccentricity value and motor power decrease, i.e., the start time, and the time at which the eccentricity value returns to a positive state (restoring stability), i.e., the end time.

[0064] Through the above embodiment, based on the analysis results of the fluctuation duration, the washing machine can intelligently adjust the drum speed and other parameters to ensure the optimal tumbling effect in different washing stages and different clothing conditions. More efficient tumbling and smoother operation reduce washing time, reduce noise, and provide a better washing experience.

[0065] In order to cope with abnormal conditions during the optimization process, in an optional embodiment, after monitoring the output power of the washing machine motor and plotting an image based on the output power to obtain the second curve, the method further includes:

[0066] Step S301: When the difference between the maximum and minimum values of the first curve is less than a third threshold and the difference between the maximum and minimum values of the second curve is greater than a fourth threshold, the set speed is reduced by a first preset step size, and the first and second curves are redrawn;

[0067] Specifically, when the difference between the maximum and minimum values of the first curve is less than the third threshold and the difference between the maximum and minimum values of the second curve is greater than the fourth threshold, it means that the eccentricity value of the washing machine drum has no obvious fluctuation, but the motor power has significant changes, that is, due to the high drum speed, the clothes stick to the drum wall and do not fall off sufficiently. Therefore, the speed is reduced by the first preset step and remeasured.

[0068] Step S302: when the difference between the maximum and minimum values of the first curve is less than a third threshold and the difference between the maximum and minimum values of the second curve is less than a fourth threshold, the set speed is increased by a first preset step size, and the first and second curves are redrawn;

[0069] Specifically, when the difference between the maximum and minimum values of the first curve is less than the third threshold value and the difference between the maximum and minimum values of the second curve is less than the fourth threshold value, it means that both the physical state inside the drum and the load of the motor have changed significantly, and the speed may be low, and the clothes may fall at a low position. Therefore, the set speed is increased by the first preset step size and remeasured.

[0070] Step S303 : When the number of repeated drawing times reaches the fifth threshold and the fluctuation duration cannot be recorded, the washing machine is controlled to run at a preset speed.

[0071] Specifically, if a valid fluctuation duration cannot be recorded after multiple attempts (reaching the second threshold number), the system will enable the preset speed to ensure that the washing machine can operate safely and stably and complete the washing task even in such extreme circumstances.

[0072] Through the above embodiments, by carefully analyzing the fluctuation characteristics of the drum eccentricity value and the motor output power, combined with the intelligent adjustment and fallback mechanism of the speed, it is ensured that even in abnormal situations, relatively effective washing can still be achieved, ensuring the stability and safety of the washing machine.

[0073] In order to ensure the accuracy of data monitoring, in an optional implementation, the above step S201 further includes:

[0074] Step S2015, obtaining the current washing stage of the washing machine, where the washing stage includes a main wash stage, a rinse wash stage, and a spin stage;

[0075] It is understandable that each stage has different effects on the movement state and beating efficiency of the clothes in the drum. Among them, in the main wash stage, since the washing machine is filled with water for the first time, the state of the clothes changes greatly. Therefore, when measuring in the main wash stage, it is necessary to ensure that the clothes have fully absorbed water, and the distribution state and wetness are relatively uniform.

[0076] Step S2016, when the current washing stage is the main wash stage, controlling the washing machine to run at a set speed for one rotation cycle after controlling the drum to swing for a second preset time period;

[0077] Therefore, if the current washing stage is the main wash stage, the drum swing control is performed for a second preset time period to ensure that the clothes are evenly distributed inside the drum and fully absorb water. After the swing is completed, the washing machine is controlled to run a complete rotation cycle at the set speed.

[0078] Step S2017: When the current washing stage is not the main wash stage, the washing machine is controlled to run a rotation cycle at a set speed.

[0079] Specifically, for non-main wash stages such as rinsing and dehydration, the washing machine is directly controlled to run a rotation cycle at a set speed without the need for shaking pretreatment.

[0080] Through the above embodiment, in the non-main wash phase, omitting the swing step and running directly at the set speed can shorten the wash time and improve the overall efficiency of the washing process. In the main wash phase, the pre-treatment of the drum by swinging the drum can evenly distribute and fully wet the clothes. The subsequent high-speed rotation can more effectively beat the clothes, remove stains, and improve washing efficiency.

[0081] It is understandable that, since the distribution state of the clothes varies greatly during the execution of different stages of the washing process, the present application further provides that the first measurement step and the second measurement step are run separately and repeatedly in each washing stage to optimize the optimal speed for the current stage, thereby ensuring that the clothes are beaten to the best effect at each stage.

[0082] In order to obtain the set speed, in an optional embodiment, step S2017 includes:

[0083] Step S20171: Obtain the weight of the laundry in the drum to obtain a target weight, and query a preset mapping relationship based on the target weight to obtain a preset speed. The preset mapping relationship is a mapping relationship between the laundry weight and the motor speed.

[0084] Specifically, a pre-set mapping relationship table is queried according to the target weight, which reflects the corresponding relationship between different clothing weights and optimal motor speeds, aiming to find a preset speed suitable for the current clothing weight.

[0085] Step S20172: reducing the preset speed by a third preset step length to obtain a set speed, where the third preset step length is greater than the first preset step length;

[0086] Specifically, the preset speed is reduced by a third preset step size to obtain the set speed. The third preset step size is usually selected to be large to obtain a conservative starting speed, so that only the speed can be increased to seek optimization without the need for bidirectional adjustment.

[0087] Step S20173, control the washing machine to run a rotation cycle at the set speed.

[0088] Specifically, the washing machine is controlled to run a complete rotation cycle at a set rotation speed, during which the eccentricity value of the drum and the motor power are monitored.

[0089] Through the above embodiment, by establishing a mapping relationship between the weight of the clothes and the rotation speed, the washing machine can dynamically select the rotation speed that best suits the current weight of the clothes, thereby optimizing the starting rotation speed for optimization and reducing the optimization time.

[0090] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the washing machine tumbling control method of the present application will be described in detail below with reference to specific embodiments.

[0091] This embodiment relates to a specific method for controlling the falling of a washing machine. Figure 3 As shown, the following steps are included:

[0092] Step S1: In any washing stage, determine whether the optimization process is being executed for the first time. If so, determine a conservative speed setting based on a preset value, check the eccentricity value and motor power within a cycle, and determine the fluctuation duration based on the eccentricity value and motor power;

[0093] Step S2: if the fluctuation duration is 0, reduce the rotation speed; if the fluctuation duration is not 0, increase the rotation speed;

[0094] Step S2: If not, adjust the current set speed according to the fluctuation duration of the previous cycle, check the eccentricity value and motor power within one cycle, and determine the fluctuation duration based on the eccentricity value and motor power;

[0095] Step S3: when the fluctuation duration is longer than that of the previous cycle, increase the rotation speed;

[0096] Step S4: cyclically monitor until the fluctuation duration decreases, and determine the set speed corresponding to the fluctuation duration that reaches the maximum value and has a small deviation between two adjacent period adjustment fluctuation durations as the target speed.

[0098] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0099] The embodiment of the present application also provides a kind of falling control device of washing machine. It should be noted that the falling control device of washing machine of the embodiment of the present application can be used for executing the falling control method for washing machine provided by the embodiment of the present application. This device is used to realize the above-mentioned embodiment and preferred embodiment, and the description that has been made will not be repeated here. As used below, the term "module" can realize the combination of software and / or hardware of predetermined function. Although the device described in the following embodiments is preferably realized with software, the realization of hardware, or the combination of software and hardware is also possible and conceived.

[0100] The following is an introduction to the falling control device for a washing machine provided in an embodiment of the present application.

[0101] Figure 4 : is a structural block diagram of a washing machine falling control device according to an embodiment of the present application. Figure 4 As shown, the device includes:

[0102] The first control unit 10 is used to control the washing machine to run a rotation cycle at a set speed, and record the time it takes for the eccentricity value of the drum of the washing machine to change from a maximum value to a preset eccentricity value during the rotation cycle to obtain a fluctuation duration;

[0103] Specifically, the eccentricity value refers to the imbalance caused by uneven distribution of clothes during the rotation of the drum, which is used to reflect the distribution of clothes inside the drum. Specifically, the process of the eccentricity value intercepted in this application from the maximum value to the preset eccentricity value is actually the process of clothes from detachment to falling. The longer the process is, the better the beating effect of the washing process.

[0104] As you can understand, the eccentricity is the distance from the center of the drum to the center of gravity of the clothing, and it changes as the drum rotates. As the clothing is thrown from one wall to another within the drum, the eccentricity fluctuates from a maximum value to a preset value. The tumbling time is then used to characterize the tumbling efficiency, optimizing the drum speed for optimal washing results.

[0105] The second control unit 20 is used to adjust the set speed to traverse the speed values of the washing machine and record the fluctuation time corresponding to each speed value;

[0106] Specifically, the goal of this process is to fine-tune the speed and observe the effect on the duration of fluctuations, thereby dynamically optimizing the speed point that achieves the best results in terms of tumbling clothes. Through iterative adjustments, the optimal solution is gradually approached, ensuring that each adjustment has a positive impact.

[0107] It is understandable that since the change in fluctuation duration is linear, the optimization process continues until the current fluctuation duration is less than the fluctuation duration of the last monitoring, that is, continuing to adjust in the same direction will lead to further performance degradation.

[0108] The third control unit 30 is configured to determine the set speed corresponding to the maximum fluctuation duration as a target speed, and control the washing machine to operate at the target speed.

[0109] Specifically, the target speed is the optimal speed found, which can maximize the beating efficiency of clothes while reducing unnecessary energy consumption and wear.

[0110] Through this embodiment, the first control unit controls the washing machine to run a rotation cycle at a set speed, and records the time it takes for the eccentricity value of the washing machine's drum to change from a maximum value to a preset eccentricity value during the rotation cycle to obtain the fluctuation duration; the second control unit adjusts the set speed to traverse the speed values of the washing machine, and records the fluctuation duration corresponding to each speed value; the third control unit determines the set speed corresponding to the maximum fluctuation duration as the target speed, and controls the washing machine to run at the target speed. The present application is set to monitor the eccentricity value of the drum during the washing process, and optimize the speed of the washing machine according to the fluctuation duration of the eccentricity value, thereby realizing dynamic adjustment of the control parameters of the washing machine as the state of the clothes changes, ensuring that the clothes can be fully beaten in each washing stage, so as to solve the problem in the prior art that due to the dynamic change of the water content of the clothes in different washing stages, it is difficult to ensure sufficient beating of the clothes by controlling according to the preset parameters, resulting in a decrease in washing efficiency.

[0111] In order to adjust the rotation speed according to the actual detection state, in an optional embodiment, the second control unit in the above steps includes:

[0112] a first control module, configured to reduce the set rotation speed by a first preset step length when the rotation cycle is the first rotation cycle and the fluctuation duration is 0;

[0113] It is understandable that when the fluctuation duration of the eccentricity value is 0, it means that the clothes are not effectively beaten inside the drum. It is probably because the drum speed is too high, causing the clothes to always stick to the wall and no beating action occurs.

[0114] Therefore, when it is detected that the fluctuation duration is 0, the set speed is reduced by a fixed increment (the first preset step mentioned above), so that the clothes can fall freely at a specific position inside the drum, producing a falling action.

[0115] It should be noted that when the fluctuation duration is 0, there is also a situation where the speed is too low and the clothes are always at the bottom of the drum. However, in actual testing, the speed is almost never set too low, so it is not used as a reference.

[0116] The second control module is configured to increase the set rotation speed by a first preset step length when the rotation cycle is the first rotation cycle and the fluctuation duration is not 0.

[0117] Specifically, when it is monitored that the fluctuation duration is not 0, it means that the current rotation speed is able to make the clothes effectively threshed inside the drum. At this time, the set rotation speed is increased by the first preset step to check whether the fluctuation duration can be extended to improve the threshing efficiency of the clothes.

[0118] Through the above-described embodiment, the drum speed is dynamically adjusted, allowing the washing machine to intelligently find the optimal speed point, effectively flying and tumbling clothes within the drum, improving washing efficiency and ensuring that clothes are fully cleaned. Furthermore, control based on the optimal speed reduces unnecessary high-speed operation, reducing energy waste, and simultaneously reducing the occurrence of excessively low and high speeds, thereby reducing wear and tear on mechanical components.

[0119] In order to achieve dynamic adjustment of the drum speed, in an optional embodiment, the second control unit further includes:

[0120] a third control module, configured to increase the set speed by a first preset step size when the fluctuation duration of the current rotation cycle is greater than the fluctuation duration of the previous rotation cycle and the set speed of the current rotation cycle is greater than the set speed of the previous rotation cycle;

[0121] Specifically, if the fluctuation duration (T1) at the current speed (Xrpm+Δrpm) is greater than the fluctuation duration (T0) at the previous speed (Xrpm), it means that the higher speed enhances the beating efficiency of the clothes, and the system should continue to increase the speed (Xrpm+Δrpm→Xrpm+2Δrpm) to further explore higher efficiency points.

[0122] The fourth control module is configured to reduce the set speed by a first preset step when the fluctuation duration of the current rotation cycle is greater than the fluctuation duration of the previous rotation cycle and the set speed of the current rotation cycle is less than the set speed of the previous rotation cycle.

[0123] Specifically, if the fluctuation duration (T1) at the current speed (Xrpm-Δrpm) is greater than the fluctuation duration (T0) at the previous speed (Xrpm), this indicates that lowering the speed will help improve the throwing efficiency, and the system should continue to lower the speed (Xrpm-Δrpm→Xrpm-2Δrpm).

[0124] Through the above embodiment, by monitoring the fluctuation duration before and after adjustment and further comparing them, the rotation speed of the drum can be dynamically adjusted, which can significantly improve the working efficiency and energy-saving performance of the washing machine.

[0125] In order to intercept the above-mentioned fluctuation duration, in an optional embodiment, the above-mentioned first control unit includes:

[0126] A first acquisition module is used to monitor the eccentricity value of the drum and draw a curve of the eccentricity value changing with time to obtain a first curve;

[0127] Specifically, by drawing a change curve of the eccentricity value in real time, the change in the distribution state of the clothes in the drum can be intuitively reflected.

[0128] a second acquisition module, configured to monitor the output power of the motor of the washing machine and draw a curve showing the output power changing over time to obtain a second curve;

[0129] Specifically, a curve of the change in the motor output power of the washing machine is drawn to reveal the low energy consumption during mixed rotation, reflecting the washing efficiency from another perspective.

[0130] A third acquisition module is configured to record the duration of the fluctuation, when the time points corresponding to the maximum values of the first curve and the second curve are the same, with the time point corresponding to the maximum value as the starting time and the time point when the eccentricity value decreases to a value less than a first threshold value as the ending time;

[0131] Specifically, when the time points corresponding to the maximum values of the first curve (eccentricity value) and the second curve (motor output power) are the same, this means that the increase in motor load coincides with the time when the beating action inside the drum occurs. The time point when the eccentricity value and the motor power decrease synchronously is intercepted, that is, the above-mentioned starting moment, until the eccentricity value returns to positive (returns to a stable state), that is, the above-mentioned end moment, and the above-mentioned fluctuation duration is obtained.

[0132] The fourth acquisition module is used to record the fluctuation duration by taking the time point corresponding to the delayed maximum value as the starting time and the time point when the eccentricity value drops to a difference less than the first threshold value from the preset eccentricity value as the ending time when the time points corresponding to the maximum values of the first curve and the second curve are different and the difference is less than the second threshold.

[0133] Specifically, the maximum values of the first and second curves occur at different times, but this time difference is less than a second threshold (a small preset time window). This indicates that while the two are not completely synchronized, they can still produce an effective striking action. The fluctuation duration is determined by measuring the time at which the eccentricity value and motor power decrease, i.e., the start time, and the time at which the eccentricity value returns to a positive state (restoring stability), i.e., the end time.

[0134] Through the above embodiment, based on the analysis results of the fluctuation duration, the washing machine can intelligently adjust the drum speed and other parameters to ensure the optimal tumbling effect in different washing stages and different clothing conditions. More efficient tumbling and smoother operation reduce washing time, reduce noise, and provide a better washing experience.

[0135] In order to deal with abnormal conditions during the optimization process, in an optional embodiment, the above-mentioned device further includes:

[0136] a fourth control unit, configured to, after monitoring the output power of the washing machine motor and plotting an image based on the output power to obtain a second curve, reduce the set speed by a first preset step size and replot the first and second curves if the difference between the maximum and minimum values of the first curve is less than a third threshold and the difference between the maximum and minimum values of the second curve is greater than a fourth threshold;

[0137] Specifically, when the difference between the maximum and minimum values of the first curve is less than the third threshold and the difference between the maximum and minimum values of the second curve is greater than the fourth threshold, it means that the eccentricity value of the washing machine drum has no obvious fluctuation, but the motor power has significant changes, that is, due to the high drum speed, the clothes stick to the drum wall and do not fall off sufficiently. Therefore, the speed is reduced by the first preset step and remeasured.

[0138] a fifth control unit, configured to increase the set speed by a first preset step size and redraw the first and second curves when the difference between the maximum and minimum values of the first curve is less than a third threshold and the difference between the maximum and minimum values of the second curve is less than a fourth threshold;

[0139] Specifically, when the difference between the maximum and minimum values of the first curve is less than the third threshold value and the difference between the maximum and minimum values of the second curve is less than the fourth threshold value, it means that both the physical state inside the drum and the load of the motor have changed significantly, and the speed may be low, and the clothes may fall at a low position. Therefore, the set speed is increased by the first preset step size and remeasured.

[0140] The sixth control unit is used to control the washing machine to run at a preset speed when the number of repeated drawing times reaches a fifth threshold and the fluctuation duration cannot be recorded.

[0141] Specifically, if a valid fluctuation duration cannot be recorded after multiple attempts (reaching the second threshold number), the system will enable the preset speed to ensure that the washing machine can operate safely and stably and complete the washing task even in such extreme circumstances.

[0142] Through the above embodiments, by carefully analyzing the fluctuation characteristics of the drum eccentricity value and the motor output power, combined with the intelligent adjustment and fallback mechanism of the speed, it is ensured that even in abnormal situations, relatively effective washing can still be achieved, ensuring the stability and safety of the washing machine.

[0143] In order to ensure the accuracy of data monitoring, in an optional embodiment, the first control unit further includes:

[0144] A fifth acquisition module is used to obtain the current washing stage of the washing machine, where the washing stage includes a main wash stage, a rinse wash stage, and a spin stage;

[0145] It is understandable that each stage has different effects on the movement state and beating efficiency of the clothes in the drum. Among them, in the main wash stage, since the washing machine is filled with water for the first time, the state of the clothes changes greatly. Therefore, when measuring in the main wash stage, it is necessary to ensure that the clothes have fully absorbed water, and the distribution state and wetness are relatively uniform.

[0146] a fifth control module, configured to control the washing machine to run a rotation cycle at a set rotation speed after controlling the drum to swing for a second preset time period when the current washing stage is a main wash stage;

[0147] Therefore, if the current washing stage is the main wash stage, the drum swing control is performed for a second preset time period to ensure that the clothes are evenly distributed inside the drum and fully absorb water. After the swing is completed, the washing machine is controlled to run a complete rotation cycle at the set speed.

[0148] The sixth control module is used to control the washing machine to run a rotation cycle at a set speed when the current washing stage is not the main wash stage.

[0149] Specifically, for non-main wash stages such as rinsing and dehydration, the washing machine is directly controlled to run a rotation cycle at a set speed without the need for shaking pretreatment.

[0150] Through the above embodiment, in the non-main wash phase, omitting the swing step and running directly at the set speed can shorten the wash time and improve the overall efficiency of the washing process. In the main wash phase, the pre-treatment of the drum by swinging the drum can evenly distribute and fully wet the clothes. The subsequent high-speed rotation can more effectively beat the clothes, remove stains, and improve washing efficiency.

[0151] It is understandable that, since the distribution state of the clothes varies greatly during the execution of different stages of the washing process, the present application further provides that the first measurement step and the second measurement step are run separately and repeatedly in each washing stage to optimize the optimal speed for the current stage, thereby ensuring that the clothes are beaten to the best effect at each stage.

[0152] In order to obtain the set speed, in an optional embodiment, the sixth control module includes:

[0153] An acquisition submodule is used to acquire the weight of the clothes in the drum, obtain a target weight, and query a preset mapping relationship according to the target weight to obtain a preset speed, where the preset mapping relationship is a mapping relationship between the clothes weight and the motor speed;

[0154] Specifically, a pre-set mapping relationship table is queried according to the target weight, which reflects the corresponding relationship between different clothing weights and optimal motor speeds, aiming to find a preset speed suitable for the current clothing weight.

[0155] a first control submodule, configured to reduce the preset speed by a third preset step length to obtain a set speed, wherein the third preset step length is greater than the first preset step length;

[0156] Specifically, the preset speed is reduced by a third preset step size to obtain the set speed. The third preset step size is usually selected to be large to obtain a conservative starting speed, so that only the speed can be increased to seek optimization without the need for bidirectional adjustment.

[0157] The second control submodule is used to control the washing machine to run a rotation cycle at a set rotation speed.

[0158] Specifically, the washing machine is controlled to run a complete rotation cycle at a set rotation speed, during which the eccentricity value of the drum and the motor power are monitored.

[0159] Through the above embodiment, by establishing a mapping relationship between the weight of the clothes and the rotation speed, the washing machine can dynamically select the rotation speed that best suits the current weight of the clothes, thereby optimizing the starting rotation speed for optimization and reducing the optimization time.
