[0007] Optionally, controlling the washing machine drum to continue rotating in the preset direction to complete the rotation cycle further includes: obtaining a preset acceleration, wherein the preset acceleration is greater than an initial acceleration, the initial acceleration representing the acceleration of the washing machine drum when it rotates in the preset direction by the first preset angle; and controlling the washing machine drum to continue rotating in the preset direction with the preset acceleration to complete the rotation cycle.

[0008] Optionally, after controlling the washing machine drum to continue rotating in the preset direction to complete the rotation cycle, the method further includes: obtaining the current number of rotation cycles; if the number of rotation cycles is greater than or equal to a preset number, controlling the washing machine drum to rotate in the opposite direction of the preset direction; if the washing machine drum rotates in the opposite direction of the preset direction by a first preset angle within one opposite rotation cycle, controlling the washing machine drum to rotate in the preset direction by a second preset angle; performing the determining step, and if the clothes are in the clumped state, controlling the washing machine drum to continue rotating in the opposite direction of the preset direction to complete the opposite rotation cycle, so that the clothes fall off in the clumped state; obtaining the number of opposite rotation cycles, and if the number of opposite rotation cycles is greater than or equal to the preset number, determining that the washing process is complete.

[0009] Optionally, the method further includes: when the number of rotation cycles is less than the preset number, obtaining the historical eccentricity value of the washing machine drum in multiple historical rotation cycles; when the multiple historical eccentricity values ​​increase sequentially in chronological order, controlling the washing machine drum to rotate sequentially in the preset direction and the opposite direction of the preset direction by the second preset angle to shake off the clumped clothes; and sequentially executing the first control step, the determining step, and the second control step until the number of rotation cycles is greater than or equal to the preset number.

[0010] Optionally, the method further includes: if the garment is in the flat state, continuing to execute the first control step and the determination step until the garment is in the clumped state.

[0011] According to another aspect of this application, a control device for a drum washing machine is provided, comprising: a first control unit, configured to control the washing machine drum to rotate in the opposite direction of the preset direction by a second preset angle when the washing machine drum rotates by a first preset angle in a preset direction within one rotation cycle, wherein the second preset angle is less than the first preset angle, and the rotation cycle represents the time it takes for the washing machine drum to rotate one revolution; a first determining unit, configured to detect the eccentricity value of the washing machine drum, obtain the current eccentricity value, and determine the state of the clothes based on the current eccentricity value, wherein the state of the clothes includes a clumped state and a flat state; and a second control unit, configured to control the washing machine drum to continue rotating in the preset direction to complete the rotation cycle when the state of the clothes is the clumped state, so that the clothes fall off in the clumped state.

Ultimately, the clothes are fully tumbled during the washing process, improving cleaning efficiency. Therefore, it can solve the problem of insufficient tumbling of clothes during the washing process in the prior art, achieving the effect of improving the cleaning efficiency of clothes.

It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

[0024] As described in the background section, in the prior art, washing machines do not sufficiently tumble clothes during the washing process. To solve the problem of insufficient tumbling of clothes during the washing process, embodiments of this application provide a control method, apparatus, computer-readable storage medium, and electronic device for a drum washing machine.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] This embodiment provides a control method for a drum washing machine that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0027] Figure 1 This is a flowchart of a control method for a drum washing machine according to an embodiment of this application. Figure 1 As shown, the method includes the following steps:

[0028] Step S201, first control step: when the washing machine drum rotates a first preset angle in a preset direction within one rotation cycle, control the washing machine drum to rotate a second preset angle in the opposite direction of the preset direction, wherein the second preset angle is smaller than the first preset angle, and the rotation cycle represents the time it takes for the washing machine drum to rotate one revolution;

[0029] Specifically, at the beginning of each rotation cycle, the washing machine drum begins to rotate in one direction, which can be either clockwise or counterclockwise. After rotating a certain angle (e.g., a first preset angle, 35°) in the preset direction, a small reverse angle is added, i.e., rotating a second preset angle (e.g., 10°) in the opposite direction, causing the clothes to clump together inside the drum. This reverse rotation aims to encourage the clothes to form clumps, increasing the pressure between them and the speed at which they fall, thereby enhancing the tumbling effect during the washing process. A rotation cycle refers to the time required for the washing machine drum to complete one full rotation (360 degrees). Within each complete rotation cycle, the drum adjusts its direction and controls its angle according to the above steps to optimize the tumbling efficiency.

[0030] Step S202, Determine the step, detect the eccentricity value of the washing machine drum, obtain the current eccentricity value, and determine the state of the clothes based on the current eccentricity value, wherein the state of the clothes includes a clumped state and a flat state.

[0031] Specifically, after rotating the roller by a second preset angle in the opposite direction of the preset direction, the eccentricity value at this time is detected. The eccentricity value of the roller during rotation can be monitored by a built-in sensor (such as an acceleration sensor, vibration sensor, or a specially designed load detection system). Based on the obtained eccentricity value, it can be determined whether the distribution of the clothes in the roller tends to be in a clumped state or a flat state.

[0032] Step S203, the second control step, when the clothes are in the clumped state, control the washing machine drum to continue rotating in the preset direction to complete the rotation cycle, so that the clothes fall off in the clumped state.

[0033] Specifically, after recognizing that the clothes are clumped, the washing machine drum will continue to rotate in the preset direction until this rotation cycle is completed. The system ensures that the drum completes a full rotation cycle (i.e., a 360-degree rotation), ensuring that the clothes reach a preset lifting height within the drum. When the drum reaches the top, the clothes will fall in a clump. Falling in a clump results in closer contact between the clothes, with more significant friction and compression, which helps improve the penetration efficiency of the detergent and the cleanliness of the clothes. By incorporating a slight reverse effect in each rotation cycle, the clothes clump together in the opposite direction, and then are lifted to the tumbling position with higher acceleration while still in a clumped state. The increased compression and falling speed of the clothes after falling in a clump improves the efficiency of wastewater exchange, thereby increasing the washing ratio and enhancing the user experience.

[0034] In this embodiment, within one rotation cycle, when the washing machine drum rotates a first preset angle in a preset direction, it is controlled to rotate a second preset angle in the opposite direction. The eccentricity value is detected, and the state of the clothes is determined based on the current eccentricity value. If the clothes are clumped together, the washing machine drum continues to rotate in the preset direction to complete the rotation cycle. Compared to existing technologies where clothes are not sufficiently agitated during washing, this application, by rotating a second preset angle in the opposite direction, causes the clothes to clump together before continuing to rotate in the preset direction, causing the clothes to fall off in a clump. This ensures the clothes are thoroughly agitated during washing, improving cleaning efficiency. Therefore, it solves the problem of insufficient agitation of clothes during washing in existing technologies, achieving the effect of improving the cleaning efficiency of clothes.

[0035] In specific implementation, step S202 can be achieved through the following steps: Step S2021: Obtain the previous eccentricity value of the washing machine drum, wherein the previous eccentricity value represents the eccentricity value when the washing machine drum rotates at the first preset angle in the preset direction; Step S2022: If the current eccentricity value is greater than the previous eccentricity value, determine that the state of the clothes is the clumped state; Step S2023: If the current eccentricity value is less than or equal to the previous eccentricity value, determine that the state of the clothes is the flat state. This method determines the state of the clothes in the drum by monitoring different eccentricity values, and determines the subsequent control steps based on the state of the clothes, thereby achieving the purpose of improving washing effect and efficiency and reducing energy consumption.

[0036] Specifically, in step S201 above, when the washing machine drum rotates at the first preset angle in a preset direction, the eccentricity value at this time is detected, thus obtaining the first eccentricity value. The current eccentricity value refers to the eccentricity value when the drum rotates at the first preset angle in the preset direction and then rotates at the second preset angle in the opposite direction. By comparing the current eccentricity value with the previous eccentricity value—that is, comparing the eccentricity value before and after the reversal—it can be determined whether the clothes have reached a clumped state after the reversal. Since the mass distribution of clumped clothes is more concentrated than that of clothes in a flat state, the eccentricity value is larger. Therefore, if the current eccentricity value is greater than the previous eccentricity value, the state of the clothes is determined to be the clumped state; if the current eccentricity value is less than or equal to the previous eccentricity value, the state of the clothes is determined to be the flat state. In specific implementation, the previous eccentricity value can be the average of multiple eccentricity values ​​collected before the reversal, and the current average value can be the average of multiple eccentricity values ​​collected after the reversal, making the eccentricity value more accurately reflect the state of the clothes.

[0037] In some optional implementations, step S203 can be achieved through the following steps: Step S2031: Obtain a preset rotational speed, wherein the preset rotational speed represents the minimum rotational speed at which the washing machine drum rotates to allow the clothes to reach a preset position, and the preset position represents the position where the falling force of the clothes is the greatest; Step S2032: Control the washing machine drum to continue rotating in the preset direction with the preset rotational speed as the initial speed to complete the rotation cycle. This method creates more suitable conditions for the clothes to fall by setting the initial speed at which the washing machine drum rotates again in the preset direction, so that the clothes fall with the best falling force, thereby improving the tumbling efficiency.

[0038] Specifically, the preset position is the specific height at which the clothes receive the maximum tumbling force during the drum's rotation. This is typically near the top of the drum, such as the upper left or upper right, where the clothes naturally fall, creating a tumbling effect. The preset rotation speed is the minimum speed required for the clothes to reach this preset position, for example, 60 rpm. Below this speed, the clothes may not reach the preset position, thus reducing the tumbling force and washing effect. Determining this rotation speed depends on factors such as the drum design, the total weight of the clothes, and the material, and requires optimization through experiments or simulations. The drum will use this preset rotation speed as its initial velocity and continue rotating in the preset direction until a complete rotation cycle is completed. In actual applications, the initial velocity at which the washing machine drum begins to rotate the first preset angle in the preset direction is also set to the aforementioned preset speed. The process of determining the preset rotation speed is explained below.

[0039] The entire washing process consists of several different steps, including the main wash, rinsing, and softening rinsing. The distribution of the clothes may change significantly during each step. Therefore, it is necessary to measure the preset spin speed for each washing step to achieve optimal tumbling height and improve washing efficiency. Taking the main wash as an example, the process of determining the preset spin speed is explained. In the main wash, the washing machine is filling with water for the first time, at which point the condition of the clothes changes considerably. Therefore, after water enters the main wash, the drum needs to be oscillated to ensure a relatively uniform distribution and wetting of the clothes before proceeding with the following measurement steps:

[0040] (1) First, measure the rotation speed at which the clothes reach the optimal drop position (preset position) during the washing process when they are wet, and set the speed minus 5 as the initial preset speed. This is because a more conservative value helps to simplify the complexity of the drum program and avoids the need to measure and compare in both directions of higher and lower speed. A lower rotation speed can be measured only in the direction of higher speed during operation, thus improving the measurement speed.

[0041] (2) According to the preset rotation speed in step (1) above, start executing steps S201, S202 and S203 to complete one rotation cycle. During this process, continuously collect the eccentricity value (which is different from the eccentricity value in step S202, and is collected after step S202, i.e., in step S203) and the motor power during the rotation in the preset direction in step S203, so that one rotation cycle can obtain a set of mapping relationships between eccentricity value and sampling time and a set of mapping relationships between motor power and sampling time, which can be plotted as curves. Start timing when the eccentricity value and motor power fluctuate downwards simultaneously or successively, and end timing when the eccentricity value returns to positive, to obtain the fluctuation duration.

[0042] (3) In the next rotation cycle, repeat the steps of (2) above and calculate a fluctuation duration again. If the fluctuation duration is longer than that in step (2), increase the preset speed. If the duration is shorter, continue to use the current preset speed until the fluctuation duration is more consistent. Then the preset speed at this time can be determined as the final preset speed.

[0043] For special situations that may occur during measurement, when there is no fluctuation in eccentricity or motor power, the following classifications are made: If there is no fluctuation in eccentricity but fluctuation in motor power, it is determined that the rotation speed is too high, and the clothes are always rotating against the drum. In this case, the rotation speed is reduced and the measurement is repeated. If there is no fluctuation in both eccentricity and motor power, it is determined that the rotation speed is too low, and the clothes detach from the drum wall and fall at a lower position. In this case, the rotation speed is increased and the measurement is repeated. Since a change in eccentricity means that the clothes are falling, this will inevitably cause a change in motor power, thus avoiding the situation where there is fluctuation in eccentricity but no change in motor power. If no fluctuation in eccentricity is observed for more than three measurements, the entire measurement process is executed at the preset rotation speed + 5.

[0044] In some optional implementations, step S203 can also be achieved through the following steps: Step S2033: Obtain a preset acceleration, wherein the preset acceleration is greater than the initial acceleration, and the initial acceleration represents the acceleration of the washing machine drum when it rotates in the preset direction at the first preset angle; Step S2034: Control the washing machine drum to continue rotating in the preset direction with the preset acceleration to complete the rotation cycle. This method increases the force and speed of the clothes falling by increasing the acceleration during the drum rotation, which can significantly improve the cleaning ability and washing efficiency of the washing machine.

[0045] Specifically, the preset acceleration is a value higher than the initial acceleration set by the washing machine control system to improve the tumbling efficiency of clothes within the drum. The initial acceleration is the acceleration when the drum begins to rotate at the first preset angle in the preset direction; this acceleration is usually gentle, aiming to gradually lift the clothes. The preset acceleration, however, is more focused on acceleration, ensuring that once the clothes clump together within the drum, they can be lifted to the preset position at a faster speed, thereby increasing the tumbling force and cleaning effect. In step S2031, the initial speed is determined as the preset rotation speed, and in step S2033, the preset acceleration is determined. Therefore, after the washing machine drum reverses direction, it continues to rotate in the original preset direction with the preset rotation speed as the initial speed and the preset acceleration until this rotation cycle is completed. The implementation of the preset acceleration allows the clothes to be lifted quickly within the drum, so that when the clothes rotate to or near the preset position, they fall at a higher speed, increasing the collision force between the clothes and between the clothes and the bottom of the drum, thus improving the cleaning and efficiency during the washing process. After completing one rotation cycle, this control strategy is repeated to maintain a highly efficient tumbling effect throughout the entire washing process. The preset rotation speed and preset acceleration are continuously adjusted during the experiment to ensure that the clothes fall at the preset position. Before reversing, the washing machine drum rotates at the preset speed and initial acceleration in the preset direction for a first preset angle. After reversing, the washing machine drum still starts at the preset speed, but continues to rotate in the preset direction with the preset acceleration until the preset cycle is completed. This is a gradual acceleration process, the purpose of which is to make the clumped clothes fall at the preset position at a faster speed, increasing the tumbling force.

[0046] In some optional embodiments, the method further includes step S204: after controlling the washing machine drum to continue rotating in the preset direction to complete the rotation cycle, obtaining the current number of rotation cycles; if the number of rotation cycles is greater than or equal to a preset number, controlling the washing machine drum to rotate in the opposite direction of the preset direction; step S205: if the washing machine drum rotates by the first preset angle in the opposite direction of the preset direction within one opposite rotation cycle, controlling the washing machine drum to rotate by the second preset angle in the preset direction; step S206: executing the determination step, and if the clothes are in the clumped state, controlling the washing machine drum to continue rotating in the opposite direction of the preset direction to complete the opposite rotation cycle, so that the clothes fall off in the clumped state; step S207: obtaining the number of opposite rotation cycles; if the number of opposite rotation cycles is greater than or equal to the preset number, determining that the washing process is complete. This method, through the above steps, controls the clothes to clump and tumble in both the preset direction and the opposite direction, ensuring that the clothes are thoroughly tumbled and washed, further improving washing efficiency.

[0047] Specifically, after the washing machine drum rotates for a preset number of cycles in a preset direction (let's say clockwise), it changes direction and washes in the opposite direction. This directional change aims to disperse the clothes and prevent them from excessively accumulating on one side or in one area inside the drum, thus ensuring a more even distribution of clothes during the washing process and improving the washing effect. The drum begins to rotate in the opposite direction (let's say counterclockwise), following steps S201 to S203 sequentially, but in the opposite direction. First, the drum rotates counterclockwise by a first preset angle to initially agitate and disperse the clothes. Then, the control system controls the drum to rotate clockwise by a second preset angle, which is still smaller than the first preset angle, to cause the clothes to clump together. Finally, while the clothes are still clumped, the drum continues to rotate counterclockwise to complete one cycle. Similarly, it rotates counterclockwise for a preset number of cycles, after which the washing process is complete. In this way, the combination of counterclockwise and clockwise rotation ensures that the clothes are effectively tumbled and cleaned in different locations.

[0048] In some optional embodiments, the method further includes step S208: when the number of rotation cycles is less than the preset number, obtaining the historical eccentricity value of the washing machine drum in multiple historical rotation cycles; step S209: when the multiple historical eccentricity values ​​increase sequentially in chronological order, controlling the washing machine drum to rotate sequentially in the preset direction and the opposite direction of the preset direction by the second preset angle, so as to shake apart the clumped clothes; step S210: sequentially executing the first control step, the determining step, and the second control step until the number of rotation cycles is greater than or equal to the preset number. This method, through the above steps, shakes apart the clothes, prevents excessive clumping, makes the distribution of clothes more even within the drum, avoids localized excessive tumbling or insufficient cleaning, and improves the uniformity and comprehensiveness of washing.

[0049] Specifically, when the current number of rotation cycles of the washing machine drum has not yet reached the preset threshold, the system begins to collect and analyze the eccentricity data of the drum in the previous rotation cycles. These eccentricity values ​​reflect the degree of vibration caused by uneven load distribution during drum rotation. Monitoring the trend of eccentricity changes allows for timely adjustments to the drum's operating strategy, preventing clothes from excessively clumping together and affecting washing performance and machine stability. The system analysis shows that the eccentricity of the drum in historical rotation cycles exhibits a continuously increasing trend. In response to this trend, the control system instructs the washing machine drum to alternately rotate in a preset direction and its opposite direction at a second preset angle. This angle of rotation is primarily used to shake apart clumps of clothing. Through alternating rotation in both directions, the clumping of clothes is effectively broken up, the clothes are redistributed, the eccentricity value is reduced, drum vibration is decreased, and the washing process is optimized, ensuring that clothes are evenly tumbled and cleaned. This ensures that clothes receive sufficient and even tumbling at each stage of the washing process, while timely shaking prevents excessive clumping, maintains stable drum operation, and ultimately maximizes washing performance and optimizes machine maintenance.

[0050] In some optional embodiments, the method further includes step S211: if the garment is in the flat state, continue executing the first control step and the determination step until the garment is in the clumped state. Through this control step, the washing machine can intelligently identify the current state of the garment and take corresponding measures to ensure that, even if it is not clumped, the relevant steps continue to be executed until it clumps, achieving the best tumbling and cleaning effect.

[0051] Specifically, when the system detects that the clothes inside the drum are laid flat—meaning they are not clumped but rather evenly distributed on the inner wall of the drum—the control system will not immediately proceed to the second control step (i.e., increasing acceleration to bring the clothes to the predetermined tumbling position). Instead, it will continue with the first control step (a slight inversion effect) and the determination step (detecting parameters such as the clothes' state and eccentricity). Through continuous slight inversion and state monitoring, the clothes are redistributed inside the drum, gradually coalescing into clumps. Clothes clumping is crucial for improving tumbling efficiency because clumped clothes generate greater friction and compression as they fall, thus exchanging wastewater more effectively and increasing the washing ratio. This cycle continues until the system detects that the clothes' state has changed from flat to clumped. At this point, the control strategy will enter the next stage: lifting the clothes to the predetermined position with higher acceleration for tumbling.

[0052] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the control method for the drum washing machine of this application will be described in detail below with reference to specific embodiments.

[0053] This embodiment relates to a specific control method for a drum washing machine, such as... Figure 2 As shown, it includes the following steps:

[0054] Step S1: Begin washing;

[0055] Step S2: Apply a small angle rotation in the opposite direction;

[0056] Step S3: Detect the eccentricity value;

[0057] Step S4: Determine if the eccentricity value increases. If yes, proceed to step S5; otherwise, return to step S2.

[0058] Step S5: Apply acceleration in the positive direction and slowly increase the acceleration;

[0059] Step S6: Complete the current rotation cycle;

[0060] Step S7: Detect the change in the eccentricity value during the detection period. If the eccentricity value increases but remains at a certain value, proceed to step S8. If the eccentricity value increases three times in a row, proceed to step S15.

[0061] Step S8: Continue executing this process, with the number of iterations in this direction n > 10;

[0062] Step S9: Shake and scatter the clothing;

[0063] Step S10: Perform this procedure in the reverse direction;

[0070] This application also provides a control device for a drum washing machine. It should be noted that the control device for the drum washing machine in this application can be used to execute the control method for a drum washing machine provided in this application. This device is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0071] The control device for a drum washing machine provided in the embodiments of this application will be described below.

[0072] Figure 5 This is a schematic diagram of the control device for a drum washing machine according to an embodiment of this application. Figure 5 As shown, the device includes:

[0073] The first control unit 10 is used to control the washing machine drum to rotate in the opposite direction of the preset direction by a second preset angle when the washing machine drum rotates by a first preset angle in a preset direction within one rotation cycle. The second preset angle is smaller than the first preset angle, and the rotation cycle represents the time it takes for the washing machine drum to rotate one revolution.

[0074] Specifically, at the beginning of each rotation cycle, the washing machine drum begins to rotate in one direction, which can be either clockwise or counterclockwise. After rotating a certain angle (e.g., a first preset angle, 35°) in the preset direction, a small reverse angle is added, i.e., rotating a second preset angle (e.g., 10°) in the opposite direction, causing the clothes to clump together inside the drum. This reverse rotation aims to encourage the clothes to form clumps, increasing the pressure between them and the speed at which they fall, thereby enhancing the tumbling effect during the washing process. A rotation cycle refers to the time required for the washing machine drum to complete one full rotation (360 degrees). Within each complete rotation cycle, the drum adjusts its direction and controls its angle according to the above steps to optimize the tumbling efficiency.

[0075] The first determining unit 20 is used to detect the eccentricity value of the washing machine drum, obtain the current eccentricity value, and determine the state of the clothes based on the current eccentricity value, wherein the state of the clothes includes a clumped state and a flat state.

[0076] Specifically, after rotating the roller by a second preset angle in the opposite direction of the preset direction, the eccentricity value at this time is detected. The eccentricity value of the roller during rotation can be monitored by a built-in sensor (such as an acceleration sensor, vibration sensor, or a specially designed load detection system). Based on the obtained eccentricity value, it can be determined whether the distribution of the clothes in the roller tends to be in a clumped state or a flat state.

[0077] The second control unit 30 is used to control the washing machine drum to continue rotating in the preset direction to complete the rotation cycle when the clothes are in the clumped state, so that the clothes fall off in the clumped state.

[0078] Specifically, after recognizing that the clothes are clumped, the washing machine drum will continue to rotate in the preset direction until this rotation cycle is completed. The system ensures that the drum completes a full rotation cycle (i.e., a 360-degree rotation), ensuring that the clothes reach a preset lifting height within the drum. When the drum reaches the top, the clothes will fall in a clump. Falling in a clump results in closer contact between the clothes, with more significant friction and compression, which helps improve the penetration efficiency of the detergent and the cleanliness of the clothes. By incorporating a slight reverse effect in each rotation cycle, the clothes clump together in the opposite direction, and then are lifted to the tumbling position with higher acceleration while still in a clumped state. The increased compression and falling speed of the clothes after falling in a clump improves the efficiency of wastewater exchange, thereby increasing the washing ratio and enhancing the user experience.

[0079] In this embodiment, within one rotation cycle, when the washing machine drum rotates a first preset angle in a preset direction, it is controlled to rotate a second preset angle in the opposite direction. The eccentricity value is detected, and the state of the clothes is determined based on the current eccentricity value. If the clothes are clumped together, the washing machine drum continues to rotate in the preset direction to complete the rotation cycle. Compared to existing technologies where clothes are not sufficiently agitated during washing, this application, by rotating a second preset angle in the opposite direction, causes the clothes to clump together before continuing to rotate in the preset direction, causing the clothes to fall off in a clump. This ensures the clothes are thoroughly agitated during washing, improving cleaning efficiency. Therefore, it solves the problem of insufficient agitation of clothes during washing in existing technologies, achieving the effect of improving the cleaning efficiency of clothes.

[0080] In its specific implementation, the first determining unit includes a first acquiring module, a first determining module, and a second determining module. The first acquiring module acquires the previous eccentricity value of the washing machine drum, wherein the previous eccentricity value represents the eccentricity value when the washing machine drum rotates at the first preset angle in the preset direction. The first determining module determines the state of the clothes as clumped when the current eccentricity value is greater than the previous eccentricity value. The second determining module determines the state of the clothes as flat when the current eccentricity value is less than or equal to the previous eccentricity value. This device determines the state of the clothes in the drum by monitoring different eccentricity values, and determines subsequent control steps based on the state of the clothes, thereby improving washing effect and efficiency and reducing energy consumption.

[0081] Specifically, in step S201 above, when the washing machine drum rotates at the first preset angle in a preset direction, the eccentricity value at this time is detected, thus obtaining the first eccentricity value. The current eccentricity value refers to the eccentricity value when the drum rotates at the first preset angle in the preset direction and then rotates at the second preset angle in the opposite direction. By comparing the current eccentricity value with the previous eccentricity value—that is, comparing the eccentricity value before and after the reversal—it can be determined whether the clothes have reached a clumped state after the reversal. Since the mass distribution of clumped clothes is more concentrated than that of clothes in a flat state, the eccentricity value is larger. Therefore, if the current eccentricity value is greater than the previous eccentricity value, the state of the clothes is determined to be the clumped state; if the current eccentricity value is less than or equal to the previous eccentricity value, the state of the clothes is determined to be the flat state. In specific implementation, the previous eccentricity value can be the average of multiple eccentricity values ​​collected before the reversal, and the current average value can be the average of multiple eccentricity values ​​collected after the reversal, making the eccentricity value more accurately reflect the state of the clothes.

[0082] In some optional embodiments, the second control unit includes a second acquisition module and a first control module. The second acquisition module is used to acquire a preset rotational speed, wherein the preset rotational speed represents the minimum rotational speed at which the washing machine drum rotates to allow the clothes to reach a preset position, and the preset position represents the position where the force of the clothes falling is the greatest. The first control module is used to control the washing machine drum to continue rotating in the preset direction with the preset rotational speed as the initial speed to complete the rotation cycle. This device creates more suitable conditions for the clothes to fall by setting the initial speed at which the washing machine drum rotates again in the preset direction, so that the clothes fall with the best falling force and improve the tumbling efficiency.

[0083] Specifically, the preset position is the specific height at which the clothes receive the maximum tumbling force during the drum's rotation. This is typically near the top of the drum, such as the upper left or upper right, where the clothes naturally fall, creating a tumbling effect. The preset rotation speed is the minimum speed required for the clothes to reach this preset position, for example, 60 rpm. Below this speed, the clothes may not reach the preset position, thus reducing the tumbling force and washing effect. Determining this rotation speed depends on factors such as the drum design, the total weight of the clothes, and the material, and requires optimization through experiments or simulations. The drum will use this preset rotation speed as its initial velocity and continue rotating in the preset direction until a complete rotation cycle is completed. In actual applications, the initial velocity at which the washing machine drum begins to rotate the first preset angle in the preset direction is also set to the aforementioned preset speed. The process of determining the preset rotation speed is explained below.

[0084] The entire washing process consists of several different steps, including the main wash, rinsing, and softening rinsing. The distribution of the clothes may change significantly during each step. Therefore, it is necessary to measure the preset spin speed for each washing step to achieve optimal tumbling height and improve washing efficiency. Taking the main wash as an example, the process of determining the preset spin speed is explained. In the main wash, the washing machine is filling with water for the first time, at which point the condition of the clothes changes considerably. Therefore, after water enters the main wash, the drum needs to be oscillated to ensure a relatively uniform distribution and wetting of the clothes before proceeding with the following measurement steps:

[0085] (1) First, measure the rotation speed at which the clothes reach the optimal drop position (preset position) during the washing process when they are wet, and set the speed minus 5 as the initial preset speed. This is because a more conservative value helps to simplify the complexity of the drum program and avoids the need to measure and compare in both directions of higher and lower speed. A lower rotation speed can be measured only in the direction of higher speed during operation, thus improving the measurement speed.

[0086] (2) According to the preset rotation speed in step (1) above, start executing steps S201, S202 and S203 to complete one rotation cycle. During this process, continuously collect the eccentricity value (which is different from the eccentricity value in step S202, and is collected after step S202, i.e., in step S203) and the motor power during the rotation in the preset direction in step S203, so that one rotation cycle can obtain a set of mapping relationships between eccentricity value and sampling time and a set of mapping relationships between motor power and sampling time, which can be plotted as curves. Start timing when the eccentricity value and motor power fluctuate downwards simultaneously or successively, and end timing when the eccentricity value returns to positive, to obtain the fluctuation duration.

[0087] (3) In the next rotation cycle, repeat the steps of (2) above and calculate a fluctuation duration again. If the fluctuation duration is longer than that in step (2), increase the preset speed. If the duration is shorter, continue to use the current preset speed until the fluctuation duration is more consistent. Then the preset speed at this time can be determined as the final preset speed.

[0088] For special situations that may occur during measurement, when there is no fluctuation in eccentricity or motor power, the following classifications are made: If there is no fluctuation in eccentricity but fluctuation in motor power, it is determined that the rotation speed is too high, and the clothes are always rotating against the drum. In this case, the rotation speed is reduced and the measurement is repeated. If there is no fluctuation in both eccentricity and motor power, it is determined that the rotation speed is too low, and the clothes detach from the drum wall and fall at a lower position. In this case, the rotation speed is increased and the measurement is repeated. Since a change in eccentricity means that the clothes are falling, this will inevitably cause a change in motor power, thus avoiding the situation where there is fluctuation in eccentricity but no change in motor power. If no fluctuation in eccentricity is observed for more than three measurements, the entire measurement process is executed at the preset rotation speed + 5.

[0089] In some optional embodiments, the second control unit further includes a third acquisition module and a second control module. The third acquisition module is used to acquire a preset acceleration, wherein the preset acceleration is greater than an initial acceleration, and the initial acceleration represents the acceleration of the washing machine drum when it rotates in the preset direction at the first preset angle. The second control module is used to control the washing machine drum to continue rotating in the preset direction at the preset acceleration to complete the rotation cycle. This device increases the force and speed at which clothes are thrown off the drum by increasing the acceleration during drum rotation, thus significantly improving the washing machine's cleaning ability and washing efficiency.

[0090] Specifically, the preset acceleration is a value higher than the initial acceleration set by the washing machine control system to improve the tumbling efficiency of clothes within the drum. The initial acceleration is the acceleration when the drum begins to rotate at the first preset angle in the preset direction; this acceleration is usually gentle, aiming to gradually lift the clothes. The preset acceleration, however, is more focused on acceleration, ensuring that once the clothes clump together within the drum, they can be lifted to the preset position at a faster speed, thereby increasing the tumbling force and cleaning effect. In step S2031, the initial speed is determined as the preset rotation speed, and in step S2033, the preset acceleration is determined. Therefore, after the washing machine drum reverses direction, it continues to rotate in the original preset direction with the preset rotation speed as the initial speed and the preset acceleration until this rotation cycle is completed. The implementation of the preset acceleration allows the clothes to be lifted quickly within the drum, so that when the clothes rotate to or near the preset position, they fall at a higher speed, increasing the collision force between the clothes and between the clothes and the bottom of the drum, thus improving the cleaning and efficiency during the washing process. After completing one rotation cycle, this control strategy is repeated to maintain a highly efficient tumbling effect throughout the entire washing process. The preset rotation speed and preset acceleration are continuously adjusted during the experiment to ensure that the clothes fall at the preset position. Before reversing, the washing machine drum rotates at the preset speed and initial acceleration in the preset direction for a first preset angle. After reversing, the washing machine drum still starts at the preset speed, but continues to rotate in the preset direction with the preset acceleration until the preset cycle is completed. This is a gradual acceleration process, the purpose of which is to make the clumped clothes fall at the preset position at a faster speed, increasing the tumbling force.

[0091] In some optional embodiments, the third control unit, fourth control unit, fifth control unit, and second determining unit are configured as follows: The third control unit is used to obtain the current number of rotation cycles after controlling the washing machine drum to continue rotating in the preset direction to complete the rotation cycle; if the number of rotation cycles is greater than or equal to a preset number, it controls the washing machine drum to rotate in the opposite direction of the preset direction; the fourth control unit is used to control the washing machine drum to rotate in the preset direction by a second preset angle if the washing machine drum rotates in the opposite direction of the preset direction by a first preset angle within one reverse rotation cycle; the fifth control unit is used to execute the determining step, and if the clothes are in the clumped state, it controls the washing machine drum to continue rotating in the opposite direction of the preset direction to complete the reverse rotation cycle, so that the clothes fall off in the clumped state; the second determining unit is used to obtain the number of reverse rotation cycles, and if the number of reverse rotation cycles is greater than or equal to the preset number, it determines that the washing process is complete. This device, through the above steps, controls the clothes to clump and tumble in both the preset direction and the opposite direction, ensuring that the clothes are thoroughly tumbled and washed, further improving washing efficiency.

[0092] Specifically, after the washing machine drum rotates for a preset number of cycles in a preset direction (let's say clockwise), it changes direction and washes in the opposite direction. This directional change aims to disperse the clothes and prevent them from excessively accumulating on one side or in one area inside the drum, thus ensuring a more even distribution of clothes during the washing process and improving the washing effect. The drum begins to rotate in the opposite direction (let's say counterclockwise), following steps S201 to S203 sequentially, but in the opposite direction. First, the drum rotates counterclockwise by a first preset angle to initially agitate and disperse the clothes. Then, the control system controls the drum to rotate clockwise by a second preset angle, which is still smaller than the first preset angle, to cause the clothes to clump together. Finally, while the clothes are still clumped, the drum continues to rotate counterclockwise to complete one cycle. Similarly, it rotates counterclockwise for a preset number of cycles, after which the washing process is complete. In this way, the combination of counterclockwise and clockwise rotation ensures that the clothes are effectively tumbled and cleaned in different locations.

[0093] In some optional embodiments, the device further includes a fourth acquisition unit, a sixth control unit, and a first execution unit. The fourth acquisition unit is used to acquire historical eccentricity values ​​of the washing machine drum over multiple historical rotation cycles when the number of rotation cycles is less than the preset number. The sixth control unit is used to control the washing machine drum to rotate sequentially by a second preset angle in the preset direction and the opposite direction of the preset direction when the multiple historical eccentricity values ​​increase sequentially in chronological order, so as to disperse the clumped clothes. The first execution unit is used to sequentially execute the first control step, the determining step, and the second control step until the number of rotation cycles is greater than or equal to the preset number. This device disperses the clothes through the above steps, preventing excessive clumping, making the distribution of clothes more even within the drum, avoiding localized excessive tumbling or insufficient cleaning, and improving the uniformity and comprehensiveness of washing.

[0094] Specifically, when the current number of rotation cycles of the washing machine drum has not yet reached the preset threshold, the system begins to collect and analyze the eccentricity data of the drum in the previous rotation cycles. These eccentricity values ​​reflect the degree of vibration caused by uneven load distribution during drum rotation. Monitoring the trend of eccentricity changes allows for timely adjustments to the drum's operating strategy, preventing clothes from excessively clumping together and affecting washing performance and machine stability. The system analysis shows that the eccentricity of the drum in historical rotation cycles exhibits a continuously increasing trend. In response to this trend, the control system instructs the washing machine drum to alternately rotate in a preset direction and its opposite direction at a second preset angle. This angle of rotation is primarily used to shake apart clumps of clothing. Through alternating rotation in both directions, the clumping of clothes is effectively broken up, the clothes are redistributed, the eccentricity value is reduced, drum vibration is decreased, and the washing process is optimized, ensuring that clothes are evenly tumbled and cleaned. This ensures that clothes receive sufficient and even tumbling at each stage of the washing process, while timely shaking prevents excessive clumping, maintains stable drum operation, and ultimately maximizes washing performance and optimizes machine maintenance.

[0095] In some optional embodiments, the device further includes a second execution unit, configured to continue executing the first control step and the determining step when the garment is in the laid-out state, until the garment is in the clumped state. Through this control step, the washing machine can intelligently identify the current state of the garment and take corresponding measures to ensure that, even if the garment is not clumped, the relevant steps continue to be executed until it clumps, achieving the best tumbling and cleaning effect.

[0096] Specifically, when the system detects that the clothes inside the drum are laid flat—meaning they are not clumped but rather evenly distributed on the inner wall of the drum—the control system will not immediately proceed to the second control step (i.e., increasing acceleration to bring the clothes to the predetermined tumbling position). Instead, it will continue with the first control step (a slight inversion effect) and the determination step (detecting parameters such as the clothes' state and eccentricity). Through continuous slight inversion and state monitoring, the clothes are redistributed inside the drum, gradually coalescing into clumps. Clothes clumping is crucial for improving tumbling efficiency because clumped clothes generate greater friction and compression as they fall, thus exchanging wastewater more effectively and increasing the washing ratio. This cycle continues until the system detects that the clothes' state has changed from flat to clumped. At this point, the control strategy will enter the next stage: lifting the clothes to the predetermined position with higher acceleration for tumbling.

[0097] The control device of the drum washing machine includes a processor and a memory. The first control unit, the first determining unit, and the second control unit, etc., are all stored as program units in the memory. The processor executes the program units stored in the memory to achieve the corresponding functions.
