A damping force peak value is determined according to a load amount in a clothes treatment drum. The damping force peak value is configured as the maximum damping force of the clothes treatment device under any load eccentricity amount, which will not cause a collision with a cabinet and cabinet displacement. When a current rotating speed is in a resonance rotating speed range, the damping force of the damper is controlled as the damping force peak value. Since the damping force of the damper is large in the resonance range, the anti-eccentricity capability of the clothes treatment device is strong. Therefore, an eccentricity threshold value is further configured as the maximum eccentricity amount allowed by the structural strength of the clothes treatment device under a target dehydration rotating speed. The execution frequency of the shaking operation can be reduced to the maximum extent, the shaking and distributing time is shortened, the dehydration time is avoided to be prolonged, meanwhile, the collision with the cabinet and the cabinet displacement problem can be avoided, and the dehydration efficiency and the cabinet displacement problem can be considered.

Description

Technical Field

[0001] The present application relates to the technical field of clothing processing equipment, and in particular to a dehydration control method and device for clothing processing equipment. Background Art

[0002] When a laundry machine spins, the load (clothes) rotates with the tub. Because the load is unevenly distributed within the tub, this creates a load eccentricity. This eccentricity causes the tub assembly to vibrate, and excessive vibration can cause the tub assembly to collide with the chassis.

[0003] To prevent the tub assembly from colliding with the housing, clothing handling devices currently typically incorporate a shock absorber, which generates friction to dampen vibrations. The greater the friction, the more effective the shock absorber is in suppressing vibrations in the resonance zone, and the greater the clothing handling device's ability to withstand maximum eccentric load. However, excessive friction can easily cause the entire device to shift, so friction cannot be increased indefinitely.

[0004] In related art, to prevent the entire clothing processing device from shifting, shock absorbers with relatively low damping force are installed. This results in a weaker anti-eccentricity capability for the clothing processing device. Consequently, the eccentricity threshold is set too low, requiring the clothing processing device to perform multiple forward and reverse rotations during dehydration to evenly distribute the clothes and reduce the load eccentricity. Repeated forward and reverse rotations, if performed too frequently in an attempt to reduce the load eccentricity, will result in a prolonged dehydration time. Summary of the Invention

[0005] In order to solve the problem of prolonged dehydration time of a clothing processing device, the present application provides a dehydration control method and related devices for a clothing processing device.

[0049] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

[0050] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner.In the following description, many specific details are provided so as to provide a full understanding of the embodiments of the present application. However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0051] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0052] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0053] In the process of the load following the rotation of the clothing processing tub, the tub assembly will vibrate due to the existence of eccentricity. When the vibration is too large, it will cause the tub assembly to collide with the box. In order to avoid the occurrence of the box collision phenomenon, a shock absorber is provided in the clothing processing equipment, and an eccentricity threshold is set based on the damping force of the shock absorber. The shock absorber is an important component of the suspension system of the clothing processing equipment, and it plays a vital role in suppressing the vibration of the tub assembly. The greater the damping force of the shock absorber, the more obvious the vibration suppression effect, that is, the stronger the anti-eccentricity ability. Therefore, if the damping force of the shock absorber is large, a larger eccentricity threshold can be set accordingly. If the damping force of the shock absorber is small, a smaller eccentricity threshold is set accordingly.

[0054] During the spin cycle, the laundry treatment device detects load eccentricity. If the detected load eccentricity exceeds a threshold, the device determines that the tub assembly is at risk of colliding with the spin box during the spin cycle. At this point, the tub assembly slows down and redistributes the load. Specifically, the tub assembly repeatedly rotates forward and backward to disperse the load, reducing the load eccentricity within the laundry treatment tub. This minimizes the load eccentricity within the laundry treatment tub, preventing collision with the spin box during the spin cycle. Detecting, determining, and dispersing the load is a continuous process of attempts until the load eccentricity within the laundry treatment tub is reduced to a level that satisfies the spin cycle. Excessive attempts to disperse the load and reduce the load eccentricity can cause the spin cycle to take longer than expected, resulting in a spin delay. More seriously, if the load eccentricity cannot be reduced to a level that satisfies the spin cycle after reaching the maximum number of attempts, the laundry treatment device will display an alarm (UNB), indicating that the load distribution is unbalanced and the spin cycle cannot be completed. Dehydration delay and UNB are issues with high user complaint rates, and are also indicators that seriously affect users' evaluation of products.

[0055] Because excessive damping force in the shock absorber can easily cause displacement and loud noise in the entire machine, the prior art uses a shock absorber with a relatively small damping force and a small eccentricity threshold. This can easily lead to dehydration delays, even alarms (UNB), and inability to complete dehydration, resulting in a poor user experience. Therefore, this application provides a dehydration control method and related device for a clothing processing device to avoid dehydration delays and cabinet displacement issues, thereby improving the user experience of the clothing processing device.

[0056] The dehydration control method and related devices of the clothing processing equipment provided by this application are described in detail below in conjunction with specific embodiments.

[0057] Figure 1 A partial structural schematic diagram of a clothes processing device according to an embodiment of the present application is shown.

[0058] like Figure 1 As shown, the laundry processing device includes a housing 101, a laundry processing tub 102, a shock absorber 103 and other necessary components. Among them, other necessary components are, for example, a driving motor ( Figure 1 Not shown), an outer tub 104 for accommodating the laundry treatment tub 102, a drainage device ( Figure 1 ), an electronic control device (not shown) for controlling components such as the drive motor and the shock absorber 103 Figure 1 (not shown) and so on. A storage space for accommodating a clothes treatment barrel 102, a shock absorber 103 and other necessary components is formed in the housing 101. The clothes treatment barrel 102 is used to hold clothes. The clothes treatment barrel 102 is rotatably arranged in the housing 101, specifically arranged in an outer barrel 104 and can be rotated by a drive motor to achieve clothes dehydration. The barrel assembly described herein includes components such as a clothes treatment barrel 102 and an outer barrel 104. The shock absorber 103 is arranged in the housing 101. The shock absorber 103 can be connected between the housing 101 and the clothes treatment barrel 102. For example, one end of the shock absorber 103 is connected to the inner wall of the housing 101, and the other end is connected to the outer wall of the outer barrel 104, so as to reduce the vibration transmitted from the clothes treatment barrel 102 to the housing 101, thereby reducing the vibration of the housing 101. In the present application, the damping force of the shock absorber 103 is adjustable.

[0059] The clothing processing device can be a washing machine or a washer-dryer. When the clothing processing device is a washing machine or a washer-dryer, the clothing processing tub 102 is the inner drum of the washing tub. A drive motor drives the clothing processing tub 102 to rotate within the outer drum 104, thereby washing and dehydrating the clothing. When the clothing processing device is a washer-dryer, the clothing processing device also includes a drying assembly connected to the washing tub for heating air and then passing it into the washing tub to dry the washed clothing.

[0060] Figure 2 A flowchart of a dehydration control method for a clothes processing device according to an embodiment of the present invention is shown. The dehydration control method can be executed by the clothes processing device, specifically by a main controller of the clothes processing device. The clothes processing device can be Figure 1 The laundry treatment appliance shown in . Figure 2 As shown, the dehydration control method of the clothes processing device includes at least steps S210 to S290, which are described in detail as follows:

[0061] In step S210, the load amount in the laundry treatment tub is obtained.

[0062] In one embodiment of the present application, inertia detection is performed by driving a driving motor of the laundry processing tub, and the load amount in the laundry processing tub is obtained by obtaining the inertia detection result of the driving motor.

[0063] Of course, in other embodiments, the load capacity can also be detected by other means, for example, a weight sensor is provided to perform weight detection by the weight sensor, and the load capacity in the clothing processing barrel is obtained by obtaining the weight detection result of the weight sensor.

[0064] In step S220, a damping force peak is determined according to the load in the laundry treatment tub, wherein the damping force peak is the maximum damping force under the load at which the laundry treatment device will not collide with the housing or shift under any load eccentricity.

[0065] Determining the peak damping force based on the load in the laundry tub may involve mapping the load in the laundry tub to obtain the peak damping force corresponding to the load. Specifically, a mapping relationship between the load and the peak damping force may be pre-set. After obtaining the load in the laundry tub in step S210, the peak damping force may be obtained based on the load and the mapping relationship between the load and the peak damping force.

[0066] In one example, in step S220, the load is divided into three types: large load, medium load, and small load, and then the load types are mapped to obtain the damping force peak value corresponding to the load. Figure 3As shown, the damping force peak value determination process may include the following steps S310 to S320, which are described in detail as follows:

[0067] In step S310, a load type is determined based on the load in the laundry treatment tub.

[0068] Exemplarily, the load types include heavy load, medium load, and light load. In step S310, the load in the laundry tub is compared with a first load threshold and a second load threshold, and the load type is determined based on the comparison result. Specifically, if the first load threshold is greater than the second load threshold, the load type is determined to be heavy load; if the load in the laundry tub is below the first load threshold and above the second load threshold, the load type is determined to be medium load; and if the load in the laundry tub is below the second load threshold, the load type is determined to be light load.

[0069] In step S320 , the damping force peak value is determined based on the load type.

[0070] Specifically, if the load type is a large load type, the first damping force F1 is used as the damping force peak value; if the load type is a medium load type, the second damping force F2 is used as the damping force peak value; if the load type is a small load type, the third damping force F3 is used as the damping force peak value.

[0071] Since the load is larger, the weight of the clothes processing equipment after the load is added is larger, according to the friction formula f = μF n (f is the friction force, μ is the friction coefficient, F n As shown in the figure, the greater the weight of the clothes processing equipment after the load is added, the greater the positive pressure F n The larger the value, the greater the friction force f between the laundry processing device and the ground, given the same friction coefficient μ. This means that the pulling force required to displace the laundry processing device is greater, and thus the damping force of the shock absorber can be greater. Therefore, the first damping force F1 is greater than the second damping force F2, and the second damping force F2 is greater than the third damping force F3.

[0072] exist Figure 3 In the illustrated embodiment, the load is divided into three types: heavy load, medium load, and light load. The algorithm logic of the subsequent steps is relatively simple and easy to implement. Of course, the three types of load are only used as an example. In actual implementation, the load can be divided into more detailed categories according to actual needs.

[0073] For example, the load is divided into five types: if the load in the laundry tub is above a first load threshold, the load type is determined to be the first type; if the load in the laundry tub is below the first load threshold and above a second load threshold, the load type is determined to be the second type; if the load in the laundry tub is below the second load threshold and above a third load threshold, the load type is determined to be the third type; if the load in the laundry tub is below the third load threshold and above a fourth load threshold, the load type is determined to be the fourth type; and if the load in the laundry tub is below the fourth load threshold, the load type is determined to be the fifth type. By dividing the load into more types, the damping force peak value of the shock absorber can be more appropriately set, thereby making the eccentricity threshold more appropriately set, and better balancing dehydration efficiency and cabinet displacement.

[0074] Among them, the first load threshold, the second load threshold, the third load threshold, the fourth load threshold, etc. are flexibly set according to actual needs and are not limited to a specific value.

[0075] In some embodiments, the load may not be classified into different types, and in subsequent steps, corresponding steps are directly executed based on the acquired load.

[0076] It should be noted that the damping force peak value corresponding to each load or load type can be obtained by performing multiple experimental calibrations on the entire clothing processing device.

[0077] In step S230, the damping force of the shock absorber is controlled to be the damping force peak value.

[0078] In one embodiment of the present application, the shock absorber is a magnetorheological shock absorber, and the damping force of the magnetorheological shock absorber can be changed according to the input voltage or current. Figure 4 As shown, the magneto-rheological shock absorber 401 is connected to a shock absorber controller 402, which is in turn connected to a main controller 403. After the main controller 403 determines the peak damping force of the magneto-rheological shock absorber 401, it further determines the voltage or current value required for the magneto-rheological shock absorber 401 to achieve this force value based on the peak damping force value. This voltage / current value is then transmitted to the shock absorber controller 402. The shock absorber controller 402 adjusts the voltage / current applied to the magneto-rheological shock absorber 401 based on the received voltage / current value, thereby changing the force value of the magneto-rheological shock absorber 401 to achieve the maximum damping force under the corresponding load.

[0079] Of course, in other embodiments, the shock absorber may also be other shock absorbers with adjustable damping force. For example, the shock absorber is a solenoid valve shock absorber, which adjusts the damping force of the shock absorber by controlling the flow size of the shock absorber oil inside the solenoid valve.

[0080] In step S240, the current load eccentricity of the laundry treatment tub is acquired.

[0081] The current load eccentricity, that is, the load eccentricity at the current moment.

[0082] In one embodiment of the present application, the eccentricity detection condition is achieved by controlling the speed of the driving motor that drives the clothing processing tub. Under the eccentricity detection condition, the speed fluctuation and the effective value of the torque current of the driving motor are detected. Based on the speed fluctuation and the effective value of the torque current, the current eccentricity of the driving motor is obtained, thereby obtaining the current load eccentricity.

[0083] It should be noted that during this eccentricity detection condition, the drive motor speed is typically below the upper limit of the resonant speed range. This means that the speed of the laundry tub is also below the upper limit of the resonant speed range. For example, when the drive motor speed reaches 93 rpm, the eccentricity detection condition is activated to detect the current load eccentricity. The upper limit of the resonant speed range is 300 rpm.

[0084] Of course, in other embodiments, an additional eccentricity detection device may be provided to detect the eccentricity of the load.

[0085] In step S250, it is determined whether to perform a shaking operation based on the current load eccentricity and a first eccentricity threshold. The shaking operation is used to reduce the load eccentricity. The first eccentricity threshold is the maximum eccentricity allowed by the structural strength of the clothing processing device at the target dehydration speed.

[0086] Specifically, in step S250, the current load eccentricity is compared with the first eccentricity threshold. If the current load eccentricity is above the first eccentricity threshold, step S260 is executed; if the current load eccentricity is below the first eccentricity threshold, step S270 is executed.

[0087] In one embodiment of the present application, Figure 5 As shown, the process of determining whether to perform the dithering operation may include the following steps S510 to S530, which are described in detail as follows:

[0088] In step S510, a target spin speed is obtained.

[0089] The target spin speed can be determined based on a user's selection. In one example, a spin speed selection menu bar is provided. By detecting a user's click or swipe operation on the spin speed selection menu bar, the target spin speed is obtained, and spin operation is performed at the target spin speed during the spin process. If the user does not operate the spin speed selection menu bar or does not operate the spin speed selection menu bar in a set triggering method, the default spin speed is used as the target spin speed, and spin operation is performed at the default spin speed during the spin process.

[0090] In one example, a maximum spin speed menu is provided. If the user triggers the menu in a set manner, for example, by clicking on the menu, the maximum spin speed is set as the target spin speed, and the clothes are dehydrated at this maximum spin speed during the dehydration process. If the user does not trigger the menu in a set manner, the default spin speed is set as the target spin speed, and the clothes are dehydrated at this default spin speed during the dehydration process. The maximum spin speed is the maximum spin speed that the clothes processing device can reach. For example, the default spin speed is 800 rpm, and the maximum spin speed is 1000 rpm.

[0091] It should be noted that the target spin speed is the maximum speed of the clothes processing tub / driving motor during the spin process.

[0092] In step S520, a first eccentricity threshold is obtained based on the target spin speed.

[0093] At each speed, the laundry machine has a maximum eccentricity allowed by its structural strength. If the current load eccentricity exceeds this maximum eccentricity, it can easily lead to structural damage. The higher the speed of the laundry tub, the greater the centrifugal force generated under the same load eccentricity and structural strength, and the more likely it is to cause structural damage to the laundry machine. In other words, the maximum eccentricity allowed by structural strength is the absolute upper limit allowed when the laundry machine is spinning at its highest speed. Any other eccentricity requirements must be less than this value.

[0094] After determining the target spin speed, the maximum eccentricity allowed by the structural strength of the corresponding laundry processing device can be determined based on the target spin speed as the first eccentricity threshold. Specifically, a mapping relationship between the target spin speed and the first eccentricity threshold can be pre-set. After obtaining the target spin speed in step S510, the corresponding first eccentricity threshold can be obtained based on the target spin speed and the mapping relationship between the target spin speed and the first eccentricity threshold.

[0095] In step S530, the current load eccentricity is compared with the first eccentricity threshold. If the current load eccentricity is above the first eccentricity threshold, it is determined that a shaking operation needs to be performed; if the current load eccentricity is below the first eccentricity threshold, it is determined that a shaking operation does not need to be performed.

[0096] exist Figure 5 In the illustrated embodiment, the first eccentricity threshold is determined based on the target spin speed, and the selection of the first eccentricity threshold is more appropriate.

[0097] In step S260 , a dithering operation is performed.

[0098] That is, the rotational speed of the driving motor is controlled to decrease to a set value, and then positive and negative rotations are performed multiple times to achieve redistribution of the load until the current load eccentricity is detected to be below the first eccentricity threshold, and then the rotational speed is increased for dewatering.

[0099] In step S270, it is determined whether the current rotational speed of the laundry treatment tub exceeds the upper limit of the resonance rotational speed range, and if the current rotational speed does not exceed the upper limit of the resonance rotational speed range, the damping force of the damper is maintained at the damping force peak value; if the current rotational speed exceeds the upper limit of the resonance rotational speed range, step S280 is performed.

[0100] To avoid dewatering with water, which causes noise of washing water hitting the laundry treatment tub, in the dewatering program, the rotational speed of the laundry treatment tub is controlled to first spin at a low speed to remove washing water from the laundry, and then to further increase the speed for dewatering, and resonance occurs in the low speed stage, for example, the resonance zone is 150 rpm-300 rpm, and the current rotational speed does not exceed the upper limit of the resonance rotational speed range, that is, it does not pass the resonance zone, at this time, the damping force of the damper is maintained at the damping force peak value to prevent the problem of hitting the cabinet.

[0101] In step S280, the damping force of the damper is controlled to be below the damping force peak value.

[0102] In an embodiment of the present application, in step S280, the damping force of the damper is controlled to be the minimum damping force of the damper. In an embodiment in which the damper is a magneto-rheological damper, the voltage / current applied to the magneto-rheological damper by the damper controller is controlled to be zero, so that the damping force of the magneto-rheological damper is reduced to the base damping force, for example, 20 N.

[0103] When the current rotational speed exceeds the upper limit of the resonance rotational speed range, that is, it has passed the resonance zone, the vibration amplitude of the laundry treatment tub in the non-resonance zone is much smaller than that in the resonance zone even at the maximum eccentricity allowed by the structural strength of the laundry treatment apparatus, that is, the vibration amplitude of the laundry treatment tub does not cause the problem of hitting the cabinet; and the load eccentricity in the non-resonance zone is generally smaller than that in the resonance zone, therefore, the damping force of the damper is reduced when the current rotational speed exceeds the upper limit of the resonance rotational speed range in the present embodiment, so that the force transmitted from the laundry treatment tub to the cabinet is reduced, thereby reducing the noise during high-speed dewatering. If the damping force of the damper is reduced to the minimum damping force of the damper, the force transmitted from the laundry treatment tub to the cabinet is the smallest at this time, and the noise during high-speed dewatering can be further reduced.

[0104] In step S290, high-speed dewatering operation is performed.

[0105] That is, the rotational speed of the driving motor, that is, the rotational speed of the laundry treatment tub, is increased to the target dewatering rotational speed until the entire dewatering process is completed.

[0106] The smaller the load eccentricity, the smaller the vibration of the barrel assembly, the smaller the force transmitted to the box through the shock absorber, and the smaller the vibration of the box. Therefore, for clothing processing equipment using a non-adjustable damping force shock absorber, in order to meet the low noise requirements and avoid the movement of the entire machine, it is hoped that the load eccentricity is as small as possible. However, the smaller the eccentricity, the more shaking operations may be required, which can easily lead to dehydration delays or even UNB. The present application sets a shock absorber with adjustable damping force, determines the damping force peak value according to the load in the clothing processing barrel, and configures the damping force peak value to be the maximum damping force under which the clothing processing equipment will not collide with the box or shift the box under any load eccentricity. Before passing the resonance zone, the damping force of the shock absorber is controlled to be the damping force peak value. Since the damping force of the shock absorber is large in the resonance zone, the clothing processing equipment has a strong anti-eccentricity ability. For this reason, the eccentricity threshold is further set to the maximum eccentricity allowed by the structural strength of the clothing processing equipment at the target dehydration speed. After passing the resonance zone, the vibration state of the clothes processing barrel has entered a stable state, the role played by the damping force is already very small, and the vibration amplitude of the barrel assembly will no longer cause the problem of hitting the box body. Therefore, the damping force of the shock absorber is reduced. When the damping force of the shock absorber is reduced to a minimum, even if the eccentricity in the barrel assembly is large and the vibration of the barrel assembly is large, the force transmitted to the box body through the shock absorber will be small, so the vibration of the box body will also be small, and the overall vibration noise level will be better. At this time, the uniform distribution of the clothes processing equipment is shaken according to the maximum eccentricity allowed by the structural strength, which can reduce the uniform distribution requirements, thereby improving the uniform distribution efficiency, shortening the uniform distribution time, and minimizing the number of times the shaking operation is performed. In other words, the dehydration efficiency and noise are both in a good state. Moreover, in Figure 2 In the illustrated embodiment, before entering the resonance zone, the damping force of the shock absorber is controlled to be the peak value of the damping force. In the resonance zone, there is no need to change the damping force of the shock absorber, which can simplify the control logic. Before entering the resonance zone, the rotation speed of the clothing processing barrel is very low and the vibration is very small. Setting the damping force of the shock absorber to the peak value of the damping force will not cause loud noise and cabinet displacement problems.

[0107] See next Figure 6 , Figure 6 The flowchart of the dehydration control method of the clothes processing equipment according to one embodiment of the present application is shown. Figure 6 As shown, the dehydration control method of the clothes processing device includes at least steps S610 to S670, which are described in detail as follows:

[0108] In step S610, the load amount in the laundry treatment tub is obtained.

[0109] In step S620, a damping force peak is determined according to the load in the laundry treatment tub, wherein the damping force peak is the maximum damping force under which the laundry treatment apparatus will not collide with or shift the housing under any load eccentricity.

[0110] In step S630, the damping force of the shock absorber is controlled to be the damping force peak value.

[0111] In step S640a, determine whether the current speed of the clothes processing tub exceeds the upper limit of the resonant speed range. If the current speed does not exceed the upper limit of the resonant speed range, execute step S650a; if the current speed exceeds the upper limit of the resonant speed range, execute step S660a.

[0112] In step S650a, the damping force of the shock absorber is maintained at the damping force peak value.

[0113] In step S660a, the damping force of the shock absorber is controlled to be the minimum damping force. After executing step S660a, the process proceeds to step S670.

[0114] In step S640b, the current load eccentricity of the laundry processing tub is acquired.

[0115] In step S650b, it is determined whether to perform a shaking operation based on the current load eccentricity and a first eccentricity threshold. The shaking operation is used to reduce the load eccentricity. The first eccentricity threshold is the maximum eccentricity allowed by the structural strength of the clothing processing device at the target dehydration speed.

[0116] Specifically, in step S650b, the current load eccentricity is compared with the first eccentricity threshold. If the current load eccentricity is above the first eccentricity threshold, step S660b is executed; if the current load eccentricity is below the first eccentricity threshold, step S670 is executed.

[0117] In step S660b, a shaking operation is performed. After step S660b is performed, if the current load eccentricity drops below the first eccentricity threshold, the process proceeds to step S670.

[0118] In step S670, a high-speed dehydration operation is performed.

[0119] It should be noted that steps S610 to S630 correspond to Figure 2 In the embodiment shown, steps S210 to S230, steps S640b, S650b, and S660b correspond to steps S240 to S260, respectively; steps S640a and S660a correspond to steps S270 to S280, respectively; and step S670 corresponds to step S290. Figure 6 The specific implementation process of each step shown is detailed in the above Figure 2 The implementation process of the corresponding steps in the embodiment shown will not be repeated here. Figure 2 The embodiment shown is different in that Figure 6In the illustrated embodiment, when the current load eccentricity of the clothes processing tub is obtained, a determination is simultaneously performed on whether the current resonance zone has been passed, and corresponding subsequent steps are simultaneously performed.

[0120] See next Figure 7 , Figure 7 The flowchart of the dehydration control method of the clothes processing equipment according to one embodiment of the present application is shown. Figure 7 As shown, the dehydration control method of the clothes processing device includes at least steps S710 to S790, which are described in detail as follows:

[0121] In step S710, the load amount in the laundry treatment tub is obtained.

[0122] In step S720, a damping force peak is determined according to the load in the laundry treatment tub, wherein the damping force peak is the maximum damping force under the load at which the laundry treatment device will not collide with the housing or shift under any load eccentricity.

[0123] In step S730, the damping force of the shock absorber is controlled to be the damping force peak value.

[0124] In step S740a, determine whether the current speed of the clothes processing tub exceeds the upper limit of the resonant speed range. If the current speed does not exceed the upper limit of the resonant speed range, execute step S750a; if the current speed exceeds the upper limit of the resonant speed range, execute step S760a.

[0125] In step S750a, the damping force of the shock absorber is maintained at the damping force peak value.

[0126] In step S760a, the damping force of the shock absorber is controlled to be the minimum damping force. After executing step S760a, the process proceeds to step S790.

[0127] In step S740b, the current load eccentricity of the laundry processing tub is acquired.

[0128] In step S750b, the current speed of the clothes processing drum is obtained and compared with the speed threshold. If the current speed is above the speed threshold, step S760b is executed; if the current speed is below the speed threshold, step S770b is executed.

[0129] In step S760b, it is determined whether to perform a shaking operation based on the current load eccentricity and a first eccentricity threshold. The shaking operation is used to reduce the load eccentricity. The first eccentricity threshold is the maximum eccentricity allowed by the structural strength of the clothing processing device at the target dehydration speed.

[0130] Specifically, in step S760b, the current load eccentricity is compared with the first eccentricity threshold. If the current load eccentricity is above the first eccentricity threshold, step S780b is executed; if the current load eccentricity is below the first eccentricity threshold, step S790 is executed.

[0131] In step S780b, a shaking operation is performed. After step S780b is performed, if the current load eccentricity drops below the first eccentricity threshold, step S790 is entered.

[0132] In step S770b, it is determined whether to perform a shaking operation based on the current load eccentricity and a second eccentricity threshold, where the second eccentricity threshold is greater than the first eccentricity threshold.

[0133] Specifically, in step S770b, the current load eccentricity is compared with the second eccentricity threshold. If the current load eccentricity is above the second eccentricity threshold, step S780b is executed; if the current load eccentricity is below the second eccentricity threshold, step S790 is executed.

[0134] In step S790, a high-speed dehydration operation is performed.

[0135] Figure 7 The specific implementation process of each step is detailed in the above Figure 2 The implementation process of the corresponding steps in the embodiment shown will not be repeated here. Figure 2 and Figure 6 The embodiment shown is different in that Figure 7 In the illustrated embodiment, different eccentricity thresholds are set based on the current rotational speed. When the current rotational speed is high, a smaller eccentricity threshold is set considering that the clothing processing device is more likely to be structurally damaged at high speed. When the current rotational speed is low, a larger eccentricity threshold is set considering that the clothing processing device is less likely to be structurally damaged at low speed. Therefore, the second eccentricity threshold is greater than the first eccentricity threshold, thereby achieving the goal of maximizing the dehydration efficiency while ensuring that the clothing processing device is not damaged.

[0136] For example, the speed threshold is 400 rpm, the resonance range is 150 rpm-300 rpm, the first eccentricity threshold is 300 g, and the second eccentricity threshold is 400 g. It should be noted that in some embodiments, the speed upper limit of the resonance speed range can also be set as the speed threshold, for example, 400 rpm. In this case, step S750b can be omitted. For example, after executing step S740b, step S740a is entered. If the judgment result of step S740a is yes, step S760b is executed. If the judgment result of step S740a is no, step S770b is executed.

[0137] It should be noted that in the aforementioned embodiments, the damping force of the shock absorber is controlled to be the peak value of the damping force before entering the resonance zone in order to simplify the control logic of the present application. In other embodiments, it can also be set to control the damping force of the shock absorber to be the minimum damping force before entering the resonance zone, and then control the damping force of the shock absorber to be the peak value of the damping force after entering the resonance zone.
