Description

Technical Field

[0001] This application relates to the field of clothing processing, specifically to a clothing processing device and its vibration control method, apparatus and storage medium. Background Technology

[0002] Vibration problems in garment processing equipment have always been a difficult problem for garment processing equipment manufacturers to solve. Among the related technologies, garment processing equipment with balancing devices has emerged. The balancing device balances the eccentricity of the clothes inside the inner drum, thereby achieving the purpose of reducing vibration.

[0003] However, during the rotation of the inner drum, when the laundry is unevenly placed in the inner drum and rotated in an unbalanced state, there is a certain speed difference between the eccentric object and the balancing device. When the balancing device is used to control the vibration of the inner drum, the vibration improvement effect of the balancing device is not fully utilized. Summary of the Invention

[0004] In view of this, embodiments of this application provide a garment processing device and its vibration control method, apparatus and storage medium, which aim to effectively improve the vibration suppression effect of the balancing device on the garment processing device.

[0005] The technical solution of this application embodiment is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a vibration control method for a garment processing device, wherein the inner drum of the garment processing device is provided with a balancing device for eccentric balancing, and the method includes:

[0007] Control the inner cylinder to run at the first set speed;

[0008] Corresponding to the inner cylinder operating at the first set speed, the operating current of the motor driving the inner cylinder to rotate is obtained;

[0009] After determining that the amplitude of the motor's operating current is increasing, the inner cylinder is controlled to start accelerating at a set time and reach the second set speed after accelerating for a set time.

[0010] Wherein, the first set rotation speed is less than the resonant rotation speed of the clothing processing device, the second set rotation speed is greater than the resonant rotation speed, the set time is the time corresponding to the peak value of the amplitude of the working current, and the set duration is greater than half of the vibration period and less than the vibration period.

[0011] In some embodiments, before controlling the inner cylinder to begin accelerating at a set time, the method further includes:

[0012] The vibration period of the inner cylinder is determined based on the amplitude change of the operating current;

[0013] The vibration period is the time difference between two adjacent peak values ​​or two adjacent trough values ​​of the amplitude of the operating current.

[0014] In some implementations, determining the vibration period of the inner cylinder based on the amplitude variation of the operating current includes:

[0015] The vibration period is obtained by acquiring the first moment when the amplitude of the operating current reaches the first peak value with a positive slope and the second moment when it reaches the second peak value. The first peak value and the second peak value are adjacent to each other.

[0016] The amplitude of the operating current is obtained at the third moment when it reaches the first trough value with a negative slope and at the fourth moment when it reaches the second trough value. Based on the difference between the fourth moment and the third moment, the vibration period is obtained, and the first trough value and the second trough value are adjacent.

[0017] In some implementations, the method further includes:

[0018] A set acceleration is determined based on the difference between the resonant rotation speed and the first set rotation speed and the vibration period. The set acceleration is the acceleration corresponding to the inner cylinder accelerating from the first set rotation speed to the second set rotation speed.

[0019] In some implementations, determining the set acceleration based on the difference between the resonant rotational speed and the first set rotational speed and the vibration period includes:

[0020] The difference between the resonant rotation speed and the first set rotation speed is divided by half of the vibration period to obtain the acceleration reference value;

[0021] The set acceleration is obtained by subtracting the acceleration correction value from the acceleration reference value.

[0022] The acceleration correction value is used to ensure that the speed of the inner cylinder when it accelerates at the set acceleration for half the duration of the vibration cycle from the set time is equal to the resonant rotational speed or the difference between the speed and the resonant rotational speed is less than the set rotational speed threshold.

[0023] In some implementations, the method further includes:

[0024] The vibration amount is obtained during the process of the inner cylinder accelerating to the second set rotational speed;

[0025] The acceleration process is determined to be abnormal based on the vibration amount and the set vibration threshold.

[0026] In some implementations, determining whether the acceleration process is abnormal based on the vibration amount and a set vibration amount threshold includes:

[0027] If the vibration amount is determined to be greater than or equal to the set vibration amount threshold, the acceleration process is judged to be abnormal.

[0028] Accordingly, the method further includes:

[0029] The inner cylinder is controlled to stop rotating or to slow down to the first set rotation speed, and then the inner cylinder is controlled to start accelerating at a set time and accelerate to the second set rotation speed.

[0030] In some implementations, the method further includes:

[0031] The inner cylinder is controlled to accelerate from the second set speed to the rated speed until dehydration is completed.

[0032] Secondly, embodiments of this application provide a vibration control device for a garment processing equipment. The inner drum of the garment processing equipment is equipped with a balancing device for eccentric balancing. The control device includes:

[0033] The control module is used to control the inner cylinder to run to a first set speed;

[0034] The acquisition module is used to acquire the operating current of the motor that drives the inner cylinder to rotate, corresponding to the inner cylinder running at the first set speed.

[0035] The control module is also used to determine that after the amplitude of the motor's operating current shows an upward trend, control the inner cylinder to start accelerating at a set time, and reach a second set speed after accelerating for a set time.

[0036] Wherein, the first set rotation speed is less than the resonant rotation speed of the clothing processing device, the second set rotation speed is greater than the resonant rotation speed, the set time is the time corresponding to the peak value of the amplitude of the working current, and the set duration is greater than half of the vibration period and less than the vibration period.

[0037] Thirdly, embodiments of this application provide a garment processing device, which includes an outer drum and an inner drum disposed within the outer drum and capable of rotation. The inner drum is equipped with a balancing device for eccentric balancing. The garment processing device further includes:

[0038] Memory, used to store computer programs;

[0039] The processor, when executing the computer program stored in the memory, implements the vibration control method described in the first aspect of the embodiments of this application.

[0040] Fourthly, embodiments of this application provide a computer storage medium storing a computer program, which, when executed by a processor, implements the vibration control method described in the first aspect of embodiments of this application.

[0041] The technical solution provided in this application embodiment controls the inner drum to run at a first set speed; corresponding to the inner drum running at the first set speed, the working current of the motor driving the inner drum to rotate is obtained; after determining that the amplitude of the motor's working current value is increasing, the inner drum is controlled to start accelerating at a set time, and reaches a second set speed after accelerating for a set time; wherein, the first set speed is less than the resonance speed of the garment processing equipment, the second set speed is greater than the resonance speed, the set time is the time corresponding to the peak value of the amplitude of the working current, and the set time is greater than half of the vibration period and less than the vibration period. This application embodiment can accelerate at a set time based on the change in the amplitude of the working current to ensure that the vibration of the entire acceleration process is small. Since the working current can be obtained at a lower speed of the inner drum, that is, eccentricity can be identified and controlled at a lower speed. In this way, the balance performance of the balancing device of the garment processing equipment can be optimized when it exceeds the resonance speed, and the vibration is low in the low-speed dehydration stage. The vibration control in the low-speed stage can also reduce the amplitude of high-speed vibration, thereby ensuring that there is no large vibration during the entire dehydration process, effectively improving dehydration noise and extending the service life of the equipment.

[0047] The technical solutions of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments provided herein are merely illustrative of this application and are not intended to limit this application. Furthermore, the embodiments provided below are some embodiments for implementing this application, and not all embodiments for implementing this application. Unless otherwise specified, the technical solutions described in the embodiments of this application can be implemented in any combination.

[0048] In the following description, the terms "first / second / third" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first / second / third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0050] This application provides a vibration control method for a clothing processing device, wherein the clothing processing device can be a drum washing machine, including an outer tub and a rotatable inner tub disposed inside the outer tub. The rotating shaft of the inner tub is mounted on the outer tub via bearings, and the inner tub is connected to a drive device for driving the inner tub to rotate. In some embodiments, the drive device is a motor, which is connected to the rotating shaft of the inner tub via a transmission mechanism. The inner tub is also provided with a balancing device for eccentric balance, for example, the balancing device can be a solid balancing ring (such as a ball balancing ring), which is not limited in this application embodiment.

[0051] For example, the ball balance ring may include at least one raceway with multiple balls disposed within it. To avoid resonant vibration of the inner drum, the ball balance ring can be used to balance the eccentricity caused by uneven distribution of clothing within the inner drum.

[0052] According to rotor dynamics theory, the ball balance ring only reaches a stable state when the dehydration speed of the garment processing equipment exceeds its resonant speed. For example, the balls within the ball balance ring can then smoothly reach and stabilize on the eccentric opposite plane or form a mass distribution with minimal vibration. Below this resonant speed, the balls within the ball balance ring are in a free state, leading to unstable vibration. This embodiment optimizes the control strategy to accurately select the acceleration point of the inner drum from the low-speed stage to the resonant speed. This optimizes the balance performance of the balancing device when the garment processing equipment exceeds the resonant speed, reducing vibration of the garment processing equipment's drums (i.e., the aforementioned inner and outer drums), effectively improving dehydration noise, and extending the equipment's service life.

[0053] Please see Figure 1 The vibration control method for a garment processing device according to embodiments of this application includes:

[0054] Step 101: Control the inner cylinder to run at the first set speed.

[0055] Here, the first set rotational speed is less than the resonant rotational speed of the garment handling equipment. It can be understood that this first set rotational speed ensures that the garments inside the inner drum adhere tightly to the inner drum wall, i.e., the eccentricity is fixed, and at this speed, it does not cause significant vibration of the inner drum. For example, the value range of this first set rotational speed can be 50–80 rpm (revolutions per minute).

[0056] It should be noted that the clothing processing equipment can predetermine the relationship between the resonant rotation speed and the amount of clothing based on vibration test data. The resonant rotation speed can be understood as the rotation speed of the inner drum that causes the clothing processing equipment to resonate. The clothing processing equipment can determine the corresponding resonant rotation speed based on the amount of clothing obtained at the beginning of startup.

[0057] Step 102: corresponding to the inner cylinder operating at the first set speed, obtain the operating current of the motor driving the inner cylinder to rotate.

[0058] It should be noted that below this resonant speed, the spheres inside the ball balance ring are in a free state. Therefore, at the first set speed, there is a certain speed difference between the unevenness of the clothes inside the inner drum and the ball balance ring. This will cause the eccentricity generated by the ball balance ring and the load (i.e., the clothes) to superimpose or cancel each other out, resulting in vibrations in the internal system as shown in the image. Figure 2 The sinusoidal vibration pattern shown can be represented by the amplitude change of the operating current of the motor driving the inner drum. Based on this, the garment processing equipment can obtain the operating current of the motor driving the inner drum at a first set rotational speed.

[0059] Step 103: After determining that the amplitude of the motor's operating current is increasing, control the inner cylinder to start accelerating at a set time, and reach the second set speed after accelerating for a set time.

[0060] Here, the second set rotational speed is greater than the resonant rotational speed of the garment processing equipment. The set time is the moment corresponding to the peak value of the amplitude wave of the working current, and the set duration is greater than half of the vibration period but less than the vibration period.

[0061] Understandably, the garment processing equipment can accelerate at a set time based on the amplitude change of the working current, cross the aforementioned resonant speed, and reach a second set speed greater than the resonant speed. This ensures that when the garment processing equipment passes the resonant speed, the eccentricity generated by the balancing device and the load is in a relative position. In other words, the balance performance of the balancing device is optimized when the garment processing equipment passes the resonant speed, resulting in lower vibration during the low-speed dehydration stage. Vibration control during the low-speed stage can also reduce the amplitude of high-speed vibration, thereby ensuring that there is no large vibration during the entire dehydration process, effectively improving dehydration noise and extending the service life of the equipment.

[0062] It should be noted that the embodiments of this application can accelerate at a set time based on the amplitude change of the working current to ensure that the vibration of the entire acceleration process is small. Since the working current can be obtained at a low speed of the inner drum, the eccentricity can be identified and controlled at a low speed. In this way, it can be ensured that there will be no large vibration during the entire dehydration process of the garment processing equipment. Compared with eccentricity control based on the amount of vibration, eccentricity balance control can be performed earlier, which effectively improves the vibration control effect.

[0063] It should be noted that before the inner cylinder begins to accelerate at a set time, it is necessary to determine that the amplitude of the motor's operating current changes periodically and obtain the corresponding vibration period. Therefore, before controlling the inner cylinder to accelerate at the set time, the vibration control method further includes: determining the vibration period of the inner cylinder based on the amplitude change of the operating current. The vibration period is the time difference between two adjacent peak values ​​or two adjacent trough values ​​of the operating current amplitude. Correspondingly, the time corresponding to the peak value of the operating current amplitude at the set time has a set duration greater than half and less than the vibration period.

[0064] Understandably, the garment processing equipment can determine the vibration period of the inner drum based on the amplitude change of the working current, and then accelerate the inner drum based on the vibration period, so that the inner drum accelerates at the appropriate time, ensuring that the eccentricity generated by the ball balance ring and the load is in the relative position when over-resonance occurs, thereby ensuring that the vibration of the internal system is minimized.

[0065] For example, determining the vibration period of the inner cylinder based on the amplitude change of the operating current includes:

[0066] The vibration period is obtained by acquiring the first moment when the amplitude of the operating current reaches the first peak value with a positive slope and the second moment when it reaches the second peak value. The first peak value and the second peak value are adjacent to each other.

[0067] acquire a third moment at which the amplitude of the operating current reaches a first valley value with a negative slope and a fourth moment at which the amplitude reaches a second valley value, and obtain the vibration period based on the difference between the fourth moment and the third moment, wherein the first valley value and the second valley value are adjacent.

[0068] It can be understood that the laundry treatment apparatus may collect the operating current of the motor at a set frequency, determine the moments corresponding to the peak values and / or valley values based on the variation trend of the amplitude of the operating current, and further obtain the vibration period, where the vibration period is the time difference between two adjacent peak values or two adjacent valley values of the amplitude of the operating current.

[0069] In an application example, Figure 2 as shown, the laundry treatment apparatus may compare the current amplitude with the previous amplitude based on the current amplitude generated by the current sensor, determine that it is in an amplitude rising stage (i.e., a positive slope stage), such as the t0-t1 segment and the t2-t3 segment, and obtain the moment corresponding to the maximum amplitude (i.e., the peak value) of the rising stage based on the amplitude comparison result, for example, the maximum amplitude A1 corresponding to the t0-t1 segment, the first moment t1 is recorded; the maximum amplitude A3 corresponding to the t2-t3 segment, the second moment t3 is recorded; and the vibration period T is determined as T=t3-t1.

[0070] In an application example, the second set rotation speed is 400rpm, as shown in Figure 2 as shown, if the inner drum starts to accelerate from the moment t3, the acceleration duration for accelerating to the second set rotation speed is T / 2+Δt, where Δt is the acceleration duration corresponding to the inner drum accelerating from the resonance rotation speed to the second set rotation speed, and Δt<T / 2. It can be understood that the acceleration duration corresponding to the inner drum accelerating from the first set rotation speed to the resonance rotation speed is T / 2, i.e., (t3-t1) / 2.

[0071] In some embodiments, the method further comprises:

[0072] determining a set acceleration based on the difference between the resonance rotation speed and the first set rotation speed and the vibration period, wherein the set acceleration is the acceleration corresponding to the inner drum accelerating from the first set rotation speed to the second set rotation speed.

[0073] In some embodiments, the determining a set acceleration based on the difference between the resonance rotation speed and the first set rotation speed and the vibration period comprises:

[0074] dividing the difference between the resonance rotation speed and the first set rotation speed by one half of the vibration period to obtain an acceleration reference value;

[0075] subtracting an acceleration correction value from the acceleration reference value to obtain the set acceleration;

[0076] The acceleration correction value is used to ensure that the speed of the inner cylinder when it accelerates at the set acceleration for half the duration of the vibration cycle from the set time is equal to the resonant rotational speed or the difference between the speed and the resonant rotational speed is less than the set rotational speed threshold.

[0077] It should be noted that, theoretically, when the inner cylinder accelerates at the aforementioned acceleration reference value for half the duration of the vibration cycle from the set time, the rotational speed of the inner cylinder is exactly above the resonant speed. However, as the rotational speed of the inner cylinder increases, the actual vibration cycle of the inner cylinder will gradually increase. Based on this, it is necessary to calibrate the acceleration reference value based on the acceleration correction value so that the set acceleration is less than the acceleration reference value. This ensures that the speed of the inner cylinder when it accelerates at the set acceleration for half the duration of the vibration cycle determined in step 103 from the set time is equal to the resonant speed or the difference between it and the resonant speed is less than the set speed threshold. The set speed threshold can be reasonably determined based on the requirements of vibration control.

[0078] In some embodiments, the method further includes:

[0079] The vibration amount is obtained during the process of the inner cylinder accelerating to the second set rotational speed;

[0080] The acceleration process is determined to be abnormal based on the vibration amount and the set vibration threshold.

[0081] For example, the aforementioned vibration level can be detected based on a vibration sensor. For instance, a MEMS (Micro-Electro-Mechanical System) sensor can be installed on the outer drum of the garment processing equipment to detect the vibration level of the outer drum.

[0082] Understandably, clothing processing equipment can obtain the vibration amount of the inner drum during the acceleration process from the first set rotation speed to the second set rotation speed based on the detection amount of MEMS sensors, and determine whether the acceleration process is abnormal based on the vibration amount and the set vibration amount threshold. In this way, abnormal vibration during the acceleration process of the inner drum can be detected in time.

[0083] For example, determining whether the acceleration process is abnormal based on the vibration amount and a set vibration amount threshold includes:

[0084] If the vibration amount is determined to be greater than or equal to the set vibration amount threshold, the acceleration process is judged to be abnormal.

[0085] Accordingly, the method further includes:

[0086] The inner cylinder is controlled to stop rotating or to slow down to the first set rotation speed, and then the inner cylinder is controlled to start accelerating at a set time and accelerate to the second set rotation speed.

[0087] The set vibration threshold can be reasonably set based on the vibration control requirements of the garment processing equipment. It is understood that if the vibration level of the inner drum remains below the set vibration threshold during the acceleration process from the first set speed to the second set speed, it indicates that the vibration during the acceleration process is reasonable and achieves a good vibration control effect. If, during the acceleration process, the vibration level is detected to be greater than or equal to the set vibration threshold, it is determined that there is an abnormality in the acceleration process. It is necessary to stop the inner drum or reduce its speed to the first set speed. Based on the operating current control strategy of this application embodiment, the vibration period of the inner drum is re-determined, and acceleration begins at the moment corresponding to the peak value of the operating current, and the speed is re-accelerated to the second set speed to ensure that the vibration during the acceleration process is at a reasonable level.

[0088] In some implementations, the method further includes:

[0089] The inner cylinder is controlled to accelerate from the second set speed to the rated speed until dehydration is completed.

[0090] Understandably, when the inner drum of the garment processing equipment exceeds the resonant speed, the garment processing equipment can control the inner drum to accelerate to the rated speed, for example, by accelerating to the maximum dehydration speed through a step-by-step acceleration method, and run at the maximum dehydration speed until dehydration is completed, at which point the motor stops driving and the dehydration program ends.

[0091] The vibration control method of this application will be illustrated below with reference to an application embodiment.

[0092] Please see Figure 3 The vibration control method of the clothing processing equipment in this application embodiment includes:

[0093] Step 301: Control the inner cylinder to run at the first set speed.

[0094] For example, the garment processing equipment may control the inner drum to run at a first set speed in response to the dehydration process, the first set speed being in the range of 50 to 80 rpm.

[0095] Step 302: corresponding to the inner cylinder running at a first set speed, obtain the operating current of the motor that drives the inner cylinder to rotate.

[0096] For example, the garment handling equipment can obtain the amplitude of the motor's operating current based on the detection value of the current sensor.

[0097] Step 303: Determine the vibration period of the inner cylinder based on the amplitude change of the working current.

[0098] For example, such as Figure 2As shown, the garment processing equipment can determine the amplitude rising stage (i.e., the positive slope stage) by comparing the current amplitude generated by the current sensor with the previous amplitude, such as the t0-t1 segment and the t2-t3 segment. Based on the amplitude comparison result, the equipment can obtain the time corresponding to the maximum amplitude (i.e., the peak value) of the rising stage. For example, the maximum amplitude value A1 corresponding to the t0-t1 segment is recorded as the first time t1; the maximum amplitude value A3 corresponding to the t2-t3 segment is recorded as the second time t3; and the vibration period T = t3 - t1 is determined.

[0099] Step 304: Control the inner cylinder to start accelerating at a set time, and reach the second set speed after the set acceleration time.

[0100] The garment handling equipment controls the inner drum to accelerate from the moment corresponding to the peak value of the operating current of the self-priming motor, crossing the resonant speed and reaching a second set speed greater than the resonant speed, for example, 400 rpm. This set duration is (t3-t1) / 2+Δt, where Δt is the acceleration time corresponding to the inner drum accelerating from the resonant speed to 400 rpm, and Δt... <T / 2。

[0101] Step 305: Determine whether the vibration amount during the acceleration process is less than the set vibration amount threshold. If not, proceed to step 306; if yes, proceed to step 307.

[0102] For example, the garment processing device can obtain the vibration amount of the inner drum during the process of accelerating from a first set speed to a second set speed based on the detection amount of the MEMS sensor, and determine whether the acceleration process is abnormal based on the vibration amount and a set vibration amount threshold. If the vibration amount is less than the set vibration amount threshold, the acceleration process is determined to be normal and step 307 is executed; if the vibration amount is greater than or equal to the set vibration amount threshold, the acceleration process is determined to be abnormal, and the inner drum can be controlled to decelerate to the first set speed and return to step 302 to re-accelerate to the second set speed, or step 306 can be executed.

[0103] Step 306: Control the inner cylinder to stop rotating.

[0104] Here, the motor stops, allowing you to manually adjust the clothes inside the drum, and then restart the spin-drying program.

[0105] Step 307: Control the inner cylinder to accelerate to the rated speed until dehydration is complete.

[0106] Here, after the inner cylinder reaches the resonant speed, the inner cylinder can be controlled to accelerate according to the dehydration program. For example, staged accelerated dehydration can be performed until dehydration is completed.

[0107] It is understood that the application embodiments of this application not only ensure the accurate selection of the acceleration time point corresponding to the resonant speed of the inner cylinder, which is conducive to making full use of the balancing device to optimize the balancing performance, but also further monitor the amount of vibration during the acceleration process. This allows for timely determination of whether there is any vibration abnormality during the acceleration process. If there is an abnormality, the machine can be stopped or the balancing device can be reused for balancing optimization, so that the inner cylinder can identify and control the eccentricity at a lower speed. In this way, it can be ensured that there will be no large vibration during the entire dehydration process.

[0108] To implement the method of the embodiments of this application, the embodiments of this application also provide a vibration control device for a garment processing equipment. Please refer to [link to relevant documentation]. Figure 4 The vibration control device includes a control module 401 and an acquisition module 402.

[0109] The control module 401 is used to control the inner drum to run to a first set speed; the acquisition module 402 is used to acquire the operating current of the motor driving the inner drum to rotate, corresponding to the inner drum running at the first set speed; the control module 401 is also used to control the inner drum to start accelerating at a set time after determining that the amplitude of the motor's operating current is increasing, and to reach a second set speed after accelerating for a set time. Wherein, the first set speed is less than the resonant speed of the clothing processing equipment, the second set speed is greater than the resonant speed, the set time is the time corresponding to the peak value of the operating current amplitude, and the set time is greater than half of the vibration period and less than the vibration period.

[0110] In some embodiments, the vibration control device further includes: a determination module 403, configured to determine the vibration period of the inner cylinder based on the amplitude change of the operating current before the inner cylinder begins to accelerate at a set time; wherein the vibration period is the time difference between two adjacent peak values ​​or two adjacent trough values ​​of the amplitude of the operating current.

[0111] In some embodiments, the determining module 403 is specifically used for:

[0112] The vibration period is obtained by acquiring the first moment when the amplitude of the operating current reaches the first peak value with a positive slope and the second moment when it reaches the second peak value. The first peak value and the second peak value are adjacent to each other.

[0113] The amplitude of the operating current is obtained at the third moment when it reaches the first trough value with a negative slope and at the fourth moment when it reaches the second trough value. Based on the difference between the fourth moment and the third moment, the vibration period is obtained, and the first trough value and the second trough value are adjacent.

[0114] In some embodiments, the control module 401 is further configured to:

[0115] A set acceleration is determined based on the difference between the resonant rotation speed and the first set rotation speed and the vibration period. The set acceleration is the acceleration corresponding to the inner cylinder accelerating from the first set rotation speed to the second set rotation speed.

[0116] In some embodiments, the control module 401 determines a set acceleration based on the difference between the resonant rotational speed and the first set rotational speed and the vibration period, including:

[0117] The difference between the resonant rotation speed and the first set rotation speed is divided by half of the vibration period to obtain the acceleration reference value;

[0118] The set acceleration is obtained by subtracting the acceleration correction value from the acceleration reference value.

[0119] The acceleration correction value is used to ensure that the speed of the inner cylinder when it accelerates at the set acceleration for half the duration of the vibration cycle from the set time is equal to the resonant rotational speed or the difference between the speed and the resonant rotational speed is less than the set rotational speed threshold.

[0120] In some embodiments, the control module 401 is further configured to:

[0121] The vibration amount is obtained during the process of the inner cylinder accelerating to the second set rotational speed;

[0122] The acceleration process is determined to be abnormal based on the vibration amount and the set vibration threshold.

[0123] In some embodiments, the control module 401 determines whether the acceleration process is abnormal based on the vibration amount and a set vibration amount threshold, including:

[0124] If the vibration amount is determined to be greater than or equal to the set vibration amount threshold, the acceleration process is judged to be abnormal.

[0125] Accordingly, the control module 401 is also used for:

[0126] The inner cylinder is controlled to stop rotating or to slow down to the first set rotation speed, and then the inner cylinder is controlled to start accelerating at a set time and accelerate to the second set rotation speed.

[0127] In some embodiments, the control module 401 is further configured to:

[0128] The inner cylinder is controlled to accelerate from the second set speed to the rated speed until dehydration is completed.
