Description

Technical Field

[0001] The present application relates to the field of washing technology, for example, to a method and device for controlling a pulsator washing machine and a pulsator washing machine. Background Art

[0002] Currently, when a washing machine spins, the inner drum spins at high speed, causing uneven clothing distribution within the drum, which can easily cause the inner drum to become eccentric. Some washing machines install balancing rings on the inner drum and fill them with balancing fluid. If the inner drum becomes offset, the balancing fluid automatically flows to the opposite side of the offset, providing balance. Other washing machines monitor the washing machine's motor or other functional modules to control the balance.

[0003] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0004] When a pulsator washing machine enters the dehydration stage, the inner drum suddenly starts to run at high speed. In this case, the inner drum often collides with the outer drum, causing the washing machine to stop. Summary of the Invention

[0024] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0025] In the description and claims of the embodiments of the present disclosure, as well as in the accompanying drawings, the terms "first," "second," and the like are used to distinguish similar items and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate to describe the embodiments of the present disclosure herein. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0026] Unless otherwise stated, the term "plurality" means two or more.

[0027] Currently, there are two main types of fully automatic washing machines in common use: pulsator washing machines and front-loading washing machines. A pulsator washing machine features an inner drum within the washtub that rotates about its central axis. A pulsator, coaxially with the inner drum, is located at the bottom of the inner drum. The rotation axes of the inner drum and pulsator are both perpendicular to the ground. The washing process primarily relies on the rotation of the pulsator to drive the water flow. However, during the dehydration process, clothes can easily accumulate on one side of the inner drum, causing the inner drum's center of mass to deviate from its rotation axis, resulting in damage to washing machine components and a reduced lifespan. Some prior art washing machines incorporate a balancing ring on the inner drum and contain a balancing fluid. If the inner drum becomes misaligned, the balancing fluid automatically flows to the opposite side of the misalignment, providing balance. During the dehydration process, the inner and outer drums are prone to collision. If the gap between the inner and outer drums exceeds a threshold or a collision occurs, the washing machine immediately stops, requiring the user to manually adjust and restart the machine.

[0028] Figure 1 is a cross-sectional schematic diagram of a pulsator washing machine provided by an embodiment of the present disclosure; Figure 2: is a cross-sectional schematic diagram of a balancing device provided by an embodiment of the present disclosure. Figure 1 、 Figure 2 As shown, the pulsator washing machine includes an inner tub 200, a balancing ring arranged at the top of the inner tub, a balancing device 300 arranged on the inner wall of the inner tub, and an outer tub 100. The balancing device 300 is used to dynamically balance and adjust the center of gravity of the inner tub 200. The balancing device 300 includes a housing 310 and a linkage assembly 320. A water inlet 312 is provided at the upper portion of the side wall of the housing 310, and a water outlet 311 connected to the drainage channel of the pulsator washing machine is provided at the bottom. The housing 310 and the inner wall of the inner tub 200 enclose a water holding chamber 330. When water is poured into the inner tub 200 at the start of the washing operation, water enters the water holding chamber 330 along the water inlet 312 until the water in the water holding chamber 330 reaches the same level as the water in the inner tub 200. The linkage assembly 320 includes an extension 321, a cover plate 322, and a transmission assembly 323. The extension 321 is connected to the housing 321 via an elastic member 324 and includes a first end 3211 and a second end 3212 disposed opposite the first end 3211. The first end 3211 is located between the inner tub 200 and the outer tub 100, with a gap between them. The second end 3212 is located within the water holding chamber 330. The cover 322 is disposed at the water outlet 311 and hingedly connected to the housing 310. The transmission assembly 323 includes a first connecting rod 3231, a second connecting rod 3232, and a crankshaft 3233. The first connecting rod 3231 is connected to the second end 3212, the second connecting rod 3232 is connected to the cover 322, and the crankshaft 3233 connects the first connecting rod 3231 and the second connecting rod 3232.

[0029] After the washing cycle is complete, the center of gravity of the inner tub 1 shifts due to the uneven distribution of laundry within the inner tub. As the center of gravity of the inner tub 200 shifts away from its center of mass, the distance between it and the outer tub 100 decreases until the first end 3211 of the extension 321 and the outer tub 100 are pressed against each other. This compresses the elastic member 324, which then applies force to the first connecting rod 3231. The end of the crankshaft 3233 connected to the second connecting rod 3232 experiences a downward force, causing the other end of the crankshaft 3233 to move upward, thereby driving the second connecting rod 3232 and the cover plate 322 upward, opening the water outlet 311. Once the inner tub 200 is balanced with the outer tub 100, the water outlet 311 stops draining, thereby adjusting the center of gravity of the inner tub 200 and improving the balance of the pulsator washing machine. Optionally, an even number of balancing devices 300 are evenly spaced and arranged along the inner wall of the inner tub 200.

[0030] Combine Figure 3 As shown, an embodiment of the present disclosure provides a method for controlling a pulsator washing machine, the pulsator washing machine including an inner tub and a balance ring disposed on the top of the inner tub, the method comprising:

[0031] S11, determining a first actual position of the gimbal.

[0032] S12: When the first actual position of the balance ring satisfies a first set condition, the pulsator washing machine is controlled to perform a pre-spinning process.

[0033] Before dehydrating clothes, the balancing device autonomously adjusts the inner tub based on changes in its center of gravity, ultimately achieving relative balance. Simultaneously, the device determines the first actual position of the balance ring. If the first actual position of the balance ring meets a first set condition, the inner tub of the pulsator washing machine is relatively balanced, and the washing machine can be controlled to perform a pre-dehydration process. This reduces the probability of the washing machine shutting down due to collision between the inner and outer tubs, thereby improving the operating efficiency and stability of the pulsator washing machine.

[0034] Using the method for controlling a pulsator washing machine provided in an embodiment of the present disclosure, after the rinsing mode ends, the pulsator washing machine performs a pre-spin process before the spin cycle based on the deviation between the first actual position and the initial position of the balance ring, monitored in real time. This process is coordinated with a balancing device located on the side wall of the inner tub of the pulsator washing machine. By controlling the pulsator washing machine to perform the pre-spin process and coordinating the dynamic balance adjustment of the inner tub by the balancing device, a smooth transition from rinsing to spin cycle is achieved, reducing collisions between the inner and outer tubs, simplifying user operations, and improving the operating efficiency of the pulsator washing machine.

[0035] In some embodiments, the first set condition includes: a deviation between the first actual position of the balancing ring and the initial position is less than or equal to a first set value; or, within a first preset time period, the deviation between the first actual position of the balancing ring and the initial position is continuously less than or equal to the first set value. This facilitates accurate control of the timing of initiating the pre-spin process in the pulsator washing machine, thereby reducing the operating time of the pulsator washing machine and improving efficiency.

[0036] The balance ring is located at the top of the inner tub. Its initial position refers to the position of the balance ring after the washing cycle of a pulsator washing machine is complete, when the center of gravity of the inner tub is located on the central axis of the inner tub and the central axes of the inner and outer tubs coincide. The balance ring's first actual position refers to the position of the balance ring detected in real time after the washing cycle is completed and before the pre-spin process begins.

[0037] Optionally, the displacement of the gimbal ring is detected by evenly and equidistantly disposing multiple displacement sensors on the inner wall of the outer tub of the pulsator washing machine. Optionally, after the pulsator washing machine is filled with water, the displacement sensor detects the position of the gimbal ring and records it as initial position data. Optionally, after the pulsator washing machine completes a washing operation, the displacement sensor detects the displacement of the gimbal ring from the initial position as first actual position data of the gimbal ring, and transmits the first actual position data of the gimbal ring to a control device of the pulsator washing machine, which then determines the deviation between the first actual position of the gimbal ring and the initial position.

[0038] Optionally, the displacement sensor measures the first actual position of the balance ring at equal intervals. For example, the interval can be 1s, 2s, 5s, 8s, or 10s. Optionally, the interval is set by the manufacturer according to different washing modes when the pulsator washing machine leaves the factory. Optionally, the interval is set by the user according to actual conditions. In this way, accurate measurement of the first actual position of the balance ring at different moments can be achieved. Optionally, when the balance ring moves to the same position as the initial position, the first actual position of the balance ring is determined. In this way, the influence of the inner barrel itself on the data can be avoided.

[0039] Optionally, if the deviation between the first actual position of the balance ring and the initial position is less than or equal to a first set value, it indicates that the inner drum of the pulsator washing machine is in a state of counterbalancing equilibrium, and the pulsator washing machine can be controlled to perform a pre-spin process. Optionally, the first set value can range from 5 mm to 20 mm, for example, the first set value can be 5 mm, 8 mm, 10 mm, 14 mm, 17 mm, or 20 mm.

[0040] Optionally, if the deviation between the first actual position of the balance ring and the initial position remains less than or equal to a first set value within a first preset time period, it indicates that the inner drum of the pulsator washing machine is in a state of counterbalancing equilibrium, and the pulsator washing machine can be controlled to perform a pre-spin process. Optionally, the first preset time period ranges from 20s to 40s. Optionally, the first preset time period ranges from 30s to 50s. Optionally, the first preset time period ranges from 40s to 60s. Optionally, multiple sensors detect data values of the first actual position of the balance ring and transmit this data to a control device, which compares this data with the data value of the initial position of the balance ring to obtain multiple deviation values between the first actual position and the initial position, and then calculates the average of the deviation values. Optionally, if the average of the deviation values between the first actual position of the balance ring and the initial position remains less than or equal to the first set value within the first preset time period, the pulsator washing machine is controlled to perform a pre-spin process. This improves the accuracy of the deviation value and the control accuracy of the pulsator washing machine, ensuring the stability of the pulsator washing machine.

[0041] Optionally, multiple angle sensors are evenly spaced on the inner wall of the outer tub of the pulsator washing machine to detect the angle of the gimbal ring's deviation from the inner / outer tub centerline. Optionally, after the pulsator washing machine is filled with water, the angle sensor detects the position of the gimbal ring and records it as initial position data. Optionally, after the pulsator washing machine completes the wash cycle, the angle sensor detects the angular displacement of the gimbal ring as data for the gimbal ring's first actual position and transmits this data to the pulsator washing machine's control device, which determines the angular deviation between the gimbal ring's first actual position and the initial position. Optionally, the angle sensor measures the gimbal ring's actual position at regular intervals, for example, the interval can be 1 second, 2 seconds, 5 seconds, 8 seconds, or 10 seconds. Optionally, the interval is set by the pulsator washing machine manufacturer based on different wash modes. Optionally, the interval is set by the user based on actual needs.

[0042] Optionally, after the washing cycle is completed, the center of gravity of the inner tub shifts due to uneven distribution of clothes in the inner tub. At this point, the extension of the balancing device on the heavier side of the inner tub presses against the outer tub, compressing the elastic member. The extension applies force to the transmission assembly, causing the second connecting rod of the transmission assembly to move the cover plate and open the water outlet, thereby adjusting the center of gravity of the inner tub.

[0043] In the above process, the displacement sensor detects the position of the balance ring in real time. When the inner drum and the outer drum are balanced with each other, that is, when the deviation between the first actual position and the initial position of the balance ring is less than or equal to the first set value, the pulsator washing machine is controlled to perform pre-dehydration processing; or, when the deviation between the actual position and the initial position of the balance ring is continuously less than or equal to the first set value within a first preset time period, the pulsator washing machine is controlled to perform pre-dehydration processing.

[0044] In some embodiments, controlling the pulsator washing machine to perform a pre-dehydration process includes: controlling the inner tub to rotate at a first speed.

[0045] Combine Figure 4 As shown, in some embodiments, the method for controlling a pulsator washing machine, after controlling the inner tub to rotate at a first speed, further includes:

[0046] S21, determining a second actual position of the gimbal.

[0047] S22: Determine whether the second actual position of the gimbal meets a second set condition.

[0048] S231: When the second actual position of the balance ring satisfies the second set condition, control the pulsator washing machine to perform a dehydration operation.

[0049] S232: When the second actual position of the balance ring does not satisfy the second set condition, the pulsator washing machine is controlled to continue the pre-spinning process so that the inner drum continues to rotate at the first speed.

[0050] When the first actual position of the gimbal ring satisfies a first set condition, the pulsator washing machine is controlled to perform a pre-spin process, causing the inner tub to rotate at a first speed. During the rotation of the inner tub at the first speed, the distribution of clothing is uneven. Due to the centrifugal force generated by the rotation of the inner tub and the gravity of the clothing, which affect the balance of the inner tub, the center of gravity of the inner tub will deviate from its center of mass. As the inner tub rotates at the first speed, the balancing assembly autonomously adjusts the center of gravity of the inner tub, draining water from the balancing assembly and continuously adjusting the center of gravity of the inner tub. During this process, a displacement sensor detects the displacement of the gimbal ring from its initial position in real time as data on the second actual position of the gimbal ring. This data is transmitted to the control device of the pulsator washing machine, which then determines whether the deviation between the second actual position of the gimbal ring and the initial position satisfies a second set condition. This enables real-time and accurate control of the pre-spin process, ensures control of the inner tub's balance, and improves the stability and safety of the pulsator washing machine.

[0051] When the deviation between the second actual position of the balance ring and the initial position meets the second set condition, it indicates that the inner drum is in a balanced state and the dehydration operation stage can be entered. Optionally, the displacement sensor measures the actual position of the balance ring once at equal intervals. For example, the interval length can be 1s, 2s, 5s, 8s or 10s. Optionally, the interval length is set by the manufacturer according to different washing modes when the pulsator washing machine leaves the factory. Optionally, the interval length is set by the user.

[0052] Optionally, if the second actual position of the balance ring does not satisfy the second set condition, the pulsator washing machine is controlled to continue pre-spinning, causing the inner tub to continue rotating at the first speed. While controlling the pulsator washing machine to continue pre-spinning, causing the inner tub to continue rotating at the first speed, the balancing device continuously adjusts the center of gravity of the inner tub to ensure stable operation of the inner tub. In this way, before the spin operation begins, the pre-spinning process is performed, and the balancing device adjusts the center of gravity of the inner tub in conjunction with the adjustment of the center of gravity of the inner tub, allowing the pulsator washing machine to smoothly begin the spin operation. This reduces the risk of the pulsator washing machine shutting down due to collision between the inner and outer drums if the spin operation is directly initiated, thereby improving the safety factor and stable performance of the pulsator washing machine and enhancing the user experience.

[0053] Optionally, when the deviation value between the first actual position and the initial position of the balance ring meets the first condition, the pulsator washing machine is controlled to enter the pre-spinning process, including: recording the first actual position before entering the pre-spinning process and setting it as the initial position of the pre-spinning process; controlling the inner barrel to rotate at a first speed.

[0054] In some embodiments, the second set condition includes: within a second preset time period, the deviation between the second actual position of the balance ring and the initial position is continuously less than or equal to a second set value, thereby facilitating accurate and efficient control of the dehydration of the pulsator washing machine.

[0055] Optionally, according to actual conditions, the range of the second set value is 0mm to 15mm, for example, the second set value can be 0mm, 3mm, 5mm, 10mm, 12mm or 15mm. Optionally, according to actual conditions, the range of the second preset time length is 20s to 60s. Optionally, multiple sensors detect the data value of the second actual position of the balance ring, and transmit the data to the control device, compare it with the data value of the initial position of the balance ring, obtain the deviation values of the second actual positions and the initial positions of the multiple balance rings, and calculate the average value of the deviation values. Optionally, when the average value of the deviation values of the second actual position and the initial position of the balance ring meets the second set condition, the pulsator washing machine is controlled to perform a dehydration operation.

[0056] Optionally, the second set condition includes: within a second preset time period, a deviation value between the actual position of the balance ring and the initial position of the pre-dehydration treatment is continuously less than or equal to a second set value.

[0057] In some embodiments, controlling the pulsator washing machine to perform a dehydration operation includes: controlling the inner tub to rotate at a second speed.

[0058] Combine Figure 5 As shown, in some embodiments, the method for controlling a pulsator washing machine, after controlling the inner tub to rotate at the second speed, further includes:

[0059] S31, determining a third actual position of the gimbal.

[0060] S32: Determine whether the third actual position of the gimbal meets a third setting condition.

[0061] S331: When the third actual position of the balance ring satisfies the third set condition, the pulsator washing machine is controlled to perform pre-spinning again.

[0062] S332: When the third actual position of the balance ring does not satisfy the third set condition, the pulsator washing machine is controlled to continue the dehydration operation, so that the inner drum continues to rotate at the second speed.

[0063] When the second actual position of the gimbal ring meets the second set condition, the pulsator washing machine is controlled to perform a spin cycle, causing the inner tub to rotate at a second speed. During the inner tub's rotation at the second speed, the distribution of clothing is also uneven. Due to the centrifugal force generated by the rotation of the inner tub and the gravity of the clothing, the balance of the inner tub is affected, causing the center of gravity of the inner tub to deviate from its center of mass, necessitating adjustment of the inner tub. The balancing assembly autonomously adjusts the center of gravity of the inner tub, draining water from the balancing assembly and continuously adjusting the center of gravity of the inner tub. During this process, a displacement sensor detects the displacement of the gimbal ring from its initial position in real time as data for the third actual position of the gimbal ring. The third actual position data is transmitted to the control device of the pulsator washing machine, which then determines whether the deviation between the third actual position of the gimbal ring and the initial position meets the third set condition. If the deviation between the third actual position of the gimbal ring and the initial position meets the third set condition, it indicates that the center of gravity of the inner tub is deviating from its center of mass and requires adjustment. In this way, the operation of the inner drum is safe and stable, which effectively solves the problems of noise and vibration during the dehydration process of the washing machine, ensures the service life of the washing machine, and improves the user experience.

[0064] Optionally, the displacement sensor measures the actual position of the balance ring at equal intervals, for example, the interval may be 1 second, 2 seconds, 5 seconds, 8 seconds, or 10 seconds. Optionally, the interval is set by the manufacturer according to different washing modes when the pulsator washing machine leaves the factory. Optionally, the interval is set by the user according to actual conditions.

[0065] When the inner tub rotates at the second speed and the third actual position of the balance ring satisfies a third set condition, the pulsator washing machine is controlled to re-perform a pre-spin process, while the balancing device continuously adjusts the center of gravity of the inner tub. Thus, the pre-spin process performed before the spin process, combined with the adjustment of the center of gravity of the inner tub by the balancing device, ensures a smooth transition from the pulsator washing machine to the spin process. The position of the balance ring is detected in real time during the spin process, further ensuring the balance and stability of the pulsator washing machine during the spin process. This reduces the risk of machine stoppages due to collisions between the inner and outer tubs during the spin process. Once the third actual position of the balance ring satisfies the third condition, the pulsator washing machine is controlled to re-perform a pre-spin process, switching the inner tub from the second speed to the first speed. This effectively reduces the risk of machine stoppages due to collisions between the inner and outer tubs, ensuring efficient spin processing.

[0066] Optionally, when the third actual position of the balancing ring does not satisfy the third set condition, the pulsator washing machine is controlled to continue the dehydration operation, causing the inner tub to continue rotating at the second speed. While controlling the pulsator washing machine to continue the dehydration operation and causing the inner tub to continue rotating at the second speed, the balancing device continuously adjusts the center of gravity of the inner tub to ensure that the pulsator washing machine quickly enters the dehydration state and stably completes the dehydration process.

[0067] In some embodiments, the third set condition includes: within a third preset time period, a deviation between the third actual position of the gimbal and the initial position is continuously greater than a third set value.

[0068] Optionally, according to actual conditions, the range of the third set value is 10mm to 30mm, for example, the third set value can be 10mm, 13mm, 18mm, 25mm or 30mm. Optionally, according to actual conditions, the range of the third preset time length is 20s to 60s. Optionally, multiple sensors detect the data value of the third actual position of the balance ring, and transmit the data to the control device, compare it with the data value of the initial position of the balance ring, obtain the deviation values of the third actual positions of the multiple balance rings from the initial positions, and calculate the average value of the deviation values. Optionally, when the average value of the deviation values of the third actual position of the balance ring from the initial position meets the third set condition, the pulsator washing machine is controlled to re-perform the pre-spinning process.

[0069] Optionally, the third setting condition includes: within a third preset time period, a deviation value between the third actual position of the balance ring and the initial position of the pre-dehydration treatment is continuously greater than a third set value.

[0070] Combine Figure 6 As shown, in some embodiments, the pulsator washing machine further includes a balancing device provided on the side wall of the inner tub, and the method for controlling the pulsator washing machine further includes:

[0071] S41, determining the amount of water in the balancing device.

[0072] S42: Determine a fourth actual position of the gimbal.

[0073] S43, when the water volume in the balancing device is less than the preset water volume and the deviation between the fourth actual position and the initial position of the balancing ring continues to be greater than the fourth preset value within the fourth preset time period, the pulsator washing machine is controlled to stop and an alarm is issued.

[0074] In the later stages of the dehydration process, water is rapidly removed from the clothing, causing the weight of the clothing to change rapidly and the distance between the inner and outer tubs to change dramatically. At this point, the amount of water in the balancing assembly varies, generating different centrifugal forces on the inner tub. The balancing assembly then drains water based on the position of the inner tub's center of gravity, adjusting the inner tub. During the dehydration phase, the pulsator washing machine first determines the amount of water in the balancing device and then determines the current position of the balancing ring, i.e., the fourth actual position. The pulsator washing machine adjusts itself based on the amount of water in the balancing device. If the balancing device detects that the amount of water is less than a preset amount, the balancing device is unable to autonomously adjust the inner tub's center of gravity, placing the washing machine in a dangerous state. If the deviation between the fourth actual position of the balancing ring and the initial position is greater than a preset value within the fourth preset time period, the inner tub's center of gravity is excessively offset and requires adjustment. However, the balancing device is insufficiently filled with water and cannot autonomously adjust the inner tub's center of gravity to a relatively balanced state. The washing machine is then shut down and an alarm is sounded. In this way, the problem of the washing machine suddenly stopping due to the inner drum deviating from its center of gravity and colliding violently with the outer drum during the dehydration operation is effectively solved. Before the inner drum and the outer drum collide, the control device controls the washing machine to stop, ensuring the service life of the washing machine and improving the user experience.

[0075] Optionally, a water level sensor is provided at the bottom of the water holding chamber of the balancing device for detecting the height of the water level in the water holding chamber. Optionally, the preset water level range is 0 to 5 mm, for example, it can be 0 mm, 3 mm or 5 mm. Optionally, the fourth preset time range is 10 to 30 seconds. Optionally, the fourth preset value range is 10 mm to 30 mm. In this way, the problem of sudden shutdown in the late stage of the dehydration stage can be effectively prevented, thereby increasing the service life of the pulsator washing machine.

[0076] Combine Figure 7 As shown, in some embodiments, the pulsator washing machine further includes an outer tub disposed outside the inner tub, a drain outlet disposed at the bottom of the outer tub, and a water quality detection sensor disposed at the drain outlet. The method for controlling the pulsator washing machine further includes:

[0077] S51, after the preset dehydration time is reached, the water quality of the water discharged from the drain outlet is determined.

[0078] S52, determining whether the water quality meets the preset standard.

[0079] S531, when the water quality meets the preset standard, the pulsator washing machine is controlled to stop working.

[0080] S532: When the water quality does not meet the preset standard, the pulsator washing machine is controlled to perform a rinsing operation.

[0081] After a preset dehydration time has elapsed, the water quality of the water discharged from the drain outlet is determined. Optionally, a sewage sensor is provided at the drain outlet of the pulsator washing machine to detect the composition of the discharged water. Optionally, the sewage sensor detects the pH of the water discharged from the drain outlet. Optionally, if the pH of the water discharged from the drain outlet falls within a set pH threshold, indicating that the laundry has been washed clean, the pulsator washing machine is controlled to stop operation.

[0082] Alternatively, if the water quality does not meet the preset standards, that is, the pH of the water discharged from the drain outlet is outside the set pH value threshold range, indicating that the clothes are not cleaned thoroughly enough, the pulsator washing machine is controlled to perform a rinsing operation. In this way, the clothes can be cleaned more thoroughly, the operation process of the pulsator washing machine is more reasonable, and the user experience is improved.

[0083] In some embodiments, the first speed is less than the second speed. Thus, the operating speed of the inner tub during the pre-spin process is less than the operating speed of the inner tub during the spin process. That is, before entering the spin process, the inner tub first operates at a low speed, and the deviation between the actual position and the initial position of the balance ring is detected in real time. Simultaneously, the balancing device adjusts the center of gravity of the inner tub, allowing the inner tub to reach a pre-balanced state before the spin process begins. This prevents the inner tub from colliding with the outer tub due to sudden high-speed operation, reduces the problem of the pulsator washing machine shutting down due to collisions between the inner and outer tubs, reduces user operation, and enables high-speed operation of the washing machine. By monitoring the deviation between the actual position and the initial position of the balance ring, the pulsator washing machine is dynamically switched between the pre-spin process and the spin process, achieving balanced operation and improving its efficiency.
