Description

Technical Field

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

[0002] Clothing processing equipment refers to equipment that can process loads such as clothing. With the development of technology, current clothing processing equipment has more and more functions. In addition to the commonly used washing function, it also includes dehydration, drying and other functions.

[0003] When the clothes processing equipment is dehydrating the load, the eccentricity of the load in the processing drum will directly affect the rotation speed of the processing drum. Therefore, the current processing method is to continuously control the rotation or shaking of the processing drum before the processing drum speed increases to level the load and reduce the eccentricity value of the load.

[0004] However, for loads with large eccentricity such as heavy clothes, the leveling process requires more times and takes longer, and is prone to produce loud noise, which reduces the user experience of the clothing processing equipment. Summary of the invention

[0005] The embodiments of the present application provide a dehydration control method, a control method for a clothing processing device, and a clothing processing device, so as to at least solve the technical problem of reduced user experience of the clothing processing device.

[0006] According to a first aspect of an embodiment of the present application, a dehydration control method is provided, which is applied to a clothes processing device, wherein the clothes processing device includes a processing drum, and the method includes:

[0007] obtaining a first eccentricity value of the dehydration load;

[0008] If the first eccentricity value exceeds a preset first eccentricity threshold, adjusting the dynamic balance parameter of the clothes processing device to increase the rotation speed resonance range of the clothes processing device;

[0009] The processing drum is controlled to rotate when its theoretical rotation speed is within the rotation speed resonance interval, and the dehydration load is selectively dehydrated according to the matching of the actual rotation speed of the processing drum with the preset set rotation speed interval.

[0010] By adopting this embodiment, when the first eccentricity value of the dehydration load exceeds the first eccentricity threshold, it proves that the eccentricity value of the dehydration load is too large. If the rotation speed of the treatment drum is forcibly increased, the amplitude of the clothing treatment device will be too large or even shifted. By adjusting the dynamic balancing parameters, the rotation speed resonance range of the clothing treatment device is increased, so that when the treatment drum is controlled to rotate, the rotation speed of the treatment drum can reach the increased rotation speed resonance range and the clothing treatment device is not prone to a large amplitude, so that the dehydration load can be at a higher rotation speed, the moisture content can be reduced, and the eccentricity value is reduced. Once the eccentricity value of the dehydration load is reduced to a certain extent, the dehydration load is dehydrated. By adopting this method, there is no need to use a lower rotation speed multiple times to level the dehydration load, which is beneficial to improving the dehydration efficiency of the dehydration load, reducing noise, and thus helping to improve the user experience of the clothing treatment device.

[0011] In combination with the first aspect, in an optional implementation of the embodiment of the present application, adjusting the dynamic balance parameters of the clothing processing device includes:

[0012] Increase the damping force of the damper of the processing drum and / or increase the mass of the balancing block of the processing drum, wherein the damping force of the damper and the mass of the balancing block are related to the maximum eccentric mass of the clothing processing device causing the processing drum to collide and shift at various rotation speed values.

[0013] By adopting this implementation method, a damper with adjustable damping force and / or a balancing block with adjustable mass is used to change the dynamic balance parameters of the clothing processing device, so that the speed resonance range of the clothing processing device is increased, which is convenient, fast and easy to control.

[0014] In combination with the first aspect, in an optional implementation of the embodiment of the present application, controlling the processing drum to rotate when its theoretical speed is within the speed resonance range and selectively dehydrating the dehydration load according to the matching of the actual speed of the processing drum with the preset set speed range includes:

[0015] When the treatment drum rotates at a theoretical speed within the increased speed resonance interval, at least one detection of the actual maximum speed of the treatment drum is performed, so that when the actual maximum speed of the treatment drum does not match the speed interval corresponding to the current detection, the next detection is performed or the dehydration load is dehydrated;

[0016] Wherein, during the detection process, the eccentricity value of the dehydration load is simultaneously affected.

[0017] By adopting the present implementation method, after increasing the speed resonance range, the processing drum can be controlled to reach a higher speed without shifting the clothing processing equipment, so that the dehydration load can have a higher speed, and the eccentricity value is easy to reduce and easy to reduce faster, so that during the next detection, the processing drum reaches a faster speed due to the reduction in the eccentricity value of the dehydration load, thereby gradually increasing the processing drum speed and improving the dehydration effect.

[0018] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the actual speed includes a first-stage speed value or a second-stage speed value, and the set speed interval includes a first-stage speed interval or a second-stage speed interval;

[0019] When the theoretical speed of the treatment drum is within the increased speed resonance interval, at least one detection of the actual maximum speed of the treatment drum is performed, so as to perform the next detection or dehydrate the dehydration load when the actual maximum speed of the treatment drum does not match the speed interval corresponding to the current detection, including:

[0020] Controlling the treatment barrel to rotate in the first stage and obtaining a first stage rotation speed value;

[0021] When the first-stage speed value does not match the first-stage speed interval, the dehydration load is dehydrated; when the first-stage speed value matches the first-stage speed interval, the dehydration is ended; or when the first-stage speed value does not match the first-stage speed interval, the dehydration load is dehydrated; when the first-stage speed value matches the first-stage speed interval, the processing drum is controlled to perform a second-stage rotation and obtain a second-stage speed value, so as to dehydrate the dehydration load according to the matching situation of the second-stage speed value and the second-stage speed interval, wherein the maximum speed value that the processing drum can reach in the first stage is less than the maximum speed value that the processing drum can reach in the second stage, and the maximum value of the first-stage speed interval is less than the maximum value of the second-stage speed interval.

[0022] With this implementation, since the eccentricity value of the dehydration load is relatively large, by setting the first stage or the first stage and the second stage, the dehydration load is first driven to rotate to reduce the eccentricity value of the dehydration load, and then the rotation speed of the processing drum is used to determine whether the dehydration load can be subsequently dehydrated. This is beneficial to maximally reduce the eccentricity value of the dehydration load, thereby making it easy to reduce the eccentricity value of the dehydration load to below the first eccentricity threshold, which helps to improve the dehydration efficiency.

[0023] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0024] If the processing drum is controlled to perform the second stage rotation, the second stage is executed at least once, and when the second stage is executed multiple times, the second stage rotation speed range corresponding to the second stage to be executed next increases.

[0025] By adopting this implementation method, the second stage can be repeatedly executed, and each time the second stage is repeated, the speed range of the second stage will increase, which is beneficial to reduce the number of repetitions of the second stage while reducing the eccentricity value of the dehydration load.

[0026] In combination with the first aspect, in an optional implementation of the embodiment of the present application, before controlling the processing drum to rotate in the second stage and obtaining the second stage speed value, so as to dehydrate the dehydration load according to the matching of the second stage speed value and the second stage speed range, the method further includes:

[0027] obtaining a first weight of the dehydrated load before the first stage and a second weight of the dehydrated load before the second stage;

[0028] If the first weight does not exceed the second weight, maintaining the dynamic balancing parameters adjusted before and during the first stage;

[0029] If the first weight exceeds the second weight, the dynamic balancing parameter is adjusted to an initial value.

[0030] Using this implementation method, the first weight exceeds the second weight, which proves that the weight of the dehydration load after the first stage is reduced, and the corresponding eccentricity value will also be reduced. At this time, the dynamic balance parameters are reset, which is beneficial for the processing drum to reach a higher rotation speed in the second stage, thereby further reducing the eccentricity value of the dehydration load.

[0031] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0032] If the first-stage speed value exceeds the first-stage speed interval, it is determined that the first-stage speed value does not match the first-stage speed interval, then controlling the processing drum to slow down and dehydrate the dehydration load;

[0033] If the first-stage speed value does not exceed the first-stage speed range, it is determined that the first-stage speed value matches the first-stage speed range, then the processing drum continues to be controlled to perform the first-stage rotation and the first-stage speed value is re-acquired until the first-stage speed value is within the first-stage fluctuation range and lasts for the first time period, thereby terminating the dehydration process.

[0034] With this implementation, if the first-stage speed value exceeds the first-stage speed interval, it proves that in the first stage, the eccentricity value of the dehydration load has been reduced to a certain extent. At this time, the dehydration load is dehydrated, which is easy to ensure the dehydration effect and reduce the moisture content of the dehydration load after dehydration, thereby improving the user experience of the clothing processing device. If the first-stage speed value does not exceed the first-stage speed interval, it proves that the eccentricity value of the dehydration load cannot be reduced to a certain extent, and the dehydration process ends.

[0035] In combination with the first aspect, in an optional implementation of the embodiment of the present application, controlling the processing drum to rotate in the second stage and obtaining a second-stage speed value, so as to dehydrate the dehydration load according to a matching condition between the second-stage speed value and the second-stage speed range, includes:

[0036] If the first-stage speed value exceeds the first-stage speed interval, the processing drum is controlled to slow down, and the processing drum is controlled to rotate in the second stage to obtain the second-stage speed value; if the second-stage speed value exceeds the second-stage speed interval, the processing drum is controlled to slow down to dehydrate the dehydration load; if the second-stage speed value does not exceed the second-stage speed interval, the processing drum is continuously controlled to rotate in the second stage and the second-stage speed value is re-obtained until the second-stage speed value is within the second-stage fluctuation range and lasts for the second time, and the dehydration process is terminated;

[0037] If the first-stage speed value does not exceed the first-stage speed range, continue to control the processing drum to perform the first-stage rotation and re-acquire the first-stage speed value until the first-stage speed value is within the first-stage fluctuation range and lasts for the first time, thereby terminating the dehydration process.

[0038] With this implementation method, the second stage is the same as the first stage. Compared with executing only the first stage, executing the second stage more easily reduces the eccentricity value of the dehydration load, thereby reducing the eccentricity value of the dehydration load to a certain extent with a greater probability, so that the dehydration load can be dehydrated normally, and it is easy to ensure the dehydration effect, reduce the moisture content of the dehydration load after dehydration, and thus improve the user experience of the clothing processing equipment.

[0039] In combination with the first aspect, in an optional implementation of the embodiment of the present application, controlling the processing cylinder to rotate in the first stage includes:

[0040] Controlling the driver of the treatment drum to start, obtaining a first maximum drum rotation speed and a first minimum drum rotation speed of the treatment drum, or obtaining a first maximum torque and a first minimum torque of the driver every time the treatment drum rotates a first number of times;

[0041] Calculating a difference between the first maximum drum speed and the first minimum drum speed, or calculating a difference between the first maximum torque and the first minimum torque to obtain a first difference;

[0042] If the difference between the first difference value and the first difference value calculated last time does not exceed a preset first difference threshold, the speed of the processing tube is controlled to increase; otherwise, the speed of the processing tube is controlled to stop increasing:

[0043] The controlling the processing cylinder to rotate in the second stage includes:

[0044] Controlling the driver of the treatment drum to start, obtaining a second maximum drum rotation speed and a second minimum drum rotation speed of the treatment drum, or obtaining a second maximum torque and a second minimum torque of the driver every time the treatment drum rotates a second number of times;

[0045] Calculating the difference between the second maximum drum speed and the second minimum drum speed, or calculating the difference between the second maximum torque and the second minimum torque to obtain a second difference;

[0046] If the difference between the second difference value and the second difference value calculated last time does not exceed a preset second difference threshold, the processing tube is controlled to increase its speed; otherwise, the processing tube is controlled to stop increasing its speed.

[0047] By adopting this implementation method, by monitoring the rotation speed of the processing drum or the torque of the driver, it is controlled whether the processing drum continues to increase in speed, which makes it easy to control the stability of the processing drum during rotation, thereby making it less likely to cause the drum to collide or the clothing processing equipment to shift, which helps to improve the user experience of the clothing processing equipment.

[0048] In combination with the first aspect, in an optional implementation of the embodiment of the present application, dehydrating the dehydrated load includes:

[0049] Controlling the start-up of a driver of the treatment cylinder;

[0050] When the rotation speed of the processing drum is within a fluctuation range, controlling the driver to drive the processing drum to increase the speed at a target acceleration;

[0051] Every time the processing drum rotates a third number of times, a third maximum drum rotation speed and a third minimum drum rotation speed of the processing drum are obtained;

[0052] Calculating the difference between the third maximum drum rotation speed and the third minimum drum rotation speed to obtain a third difference;

[0053] Calculating a change slope of the third difference and a change slope of a rotation speed of the treatment drum;

[0054] If the change slope of the third difference does not exceed the change slope of the rotation speed, the processing tube is controlled to continue to increase its speed; otherwise, the processing tube is controlled to stop increasing its speed.

[0055] With this implementation, when dehydrating, the speed of the processing drum is first increased to a relatively stable range, and then the speed of the processing drum is gradually increased at the target acceleration, which makes it less likely for the drum to collide or the clothing processing device to shift. At the same time, during the speed increase process, the speed of the processing drum is used to monitor the stability of the clothing processing device, further reducing the probability of drum collision and displacement.

[0056] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0057] If the second eccentricity value of the dehydration load exceeds the first eccentricity threshold, increasing the first eccentricity threshold to obtain a second eccentricity threshold, wherein the second eccentricity threshold is greater than the second eccentricity value;

[0058] The second eccentricity threshold is used as a limiting condition for the treatment drum to drive the dehydration load to rotate, so that the treatment drum can drive the dehydration load to rotate;

[0059] Obtaining the eccentricity value of the dehydration load to obtain the first eccentricity value;

[0060] If the first eccentricity value exceeds the first eccentricity threshold value within a preset third time period, the step of adjusting the dynamic balance parameter of the clothing processing device is performed to increase the rotation speed resonance range of the clothing processing device;

[0061] Otherwise, a preset dehydration program is executed, wherein the preset dehydration program includes a dehydration program executed when the eccentricity value of the dehydration load does not exceed the first eccentricity threshold.

[0062] By adopting this implementation method, the first eccentricity value is increased, so that the processing drum can drive the dehydration load greater than the first eccentricity value to rotate, thereby quickly reducing the eccentricity value of the dehydration load, avoiding the inability to trigger the clothing processing equipment to drive the dehydration load to rotate due to the eccentricity value of the dehydration load being too large, and helping to quickly reduce the eccentricity value of the dehydration load.

[0063] According to a second aspect of an embodiment of the present application, a control method for a clothing processing device is provided, including the method described above.

[0064] According to a third aspect of an embodiment of the present application, a clothes processing device is provided, wherein the clothes processing device adopts the above-described method during dehydration.

[0065] The technical effects obtained by the above-mentioned second to third aspects are similar to the technical effects obtained by the corresponding technical means in the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] The present application provides a dehydration control method for use in a clothing processing device, wherein the clothing processing device includes a processing drum, Figure 1 The flow chart of the dehydration control method shown is that the method includes the following processing process.

[0073] S100, obtaining a first eccentricity value of a dehydration load.

[0074] Taking the dehydration of clothes by a washing machine as an example, the washing machine is used as a clothes processing device, the inner drum of the washing machine is used as a processing drum, and the clothes are the dehydration load. During the dehydration control process, the first eccentricity value of the dehydration load is first collected. Among them, the first eccentricity value and the eccentricity value to be obtained subsequently can be obtained using existing algorithms or measuring instruments, and this embodiment does not specifically limit this.

[0075] S102: If the first eccentricity value exceeds a preset first eccentricity threshold, adjusting a dynamic balance parameter of the clothes processing device to increase a rotation speed resonance range of the clothes processing device.

[0076] It should be noted that the first eccentricity threshold is a common safety dehydration threshold for clothing processing equipment, that is, only when the eccentricity value of the clothing does not exceed the first eccentricity threshold can the processing drum be controlled to rotate and the clothing be dehydrated, and during the dehydration process, there will be no collision with the drum or displacement of the clothing processing equipment. Preferably, the first eccentricity threshold can be obtained through experiments, and this embodiment does not specifically limit this.

[0077] The dynamic balance parameter refers to a parameter that can affect the collision and / or displacement of the clothes processing device during the dehydration process. When the dynamic balance parameter is adjusted, the speed resonance range of the clothes processing device will increase, so that the clothes processing device will not collide with the drum or shift when driving the dehydration load to rotate at a higher speed.

[0078] Specifically, resonance occurs when the driving frequency of the washing machine is close to or the same as the natural frequency of the washing machine, and the washing machine will vibrate violently and make noise.

[0079] S104, controlling the processing drum to rotate when its theoretical rotation speed is within the rotation speed resonance range and selectively dehydrating the dehydration load according to the matching of the actual rotation speed of the processing drum with the preset set rotation speed range.

[0080] The processing tube is driven by the driver to rotate. When controlling the rotation of the processing tube, the working current or working voltage of the driver is set so that the driver drives the processing tube to rotate. The maximum speed that the processing tube can reach is affected by the eccentricity value. Based on this principle, the processing tube can be rotated within the speed resonance range by setting the working parameters of the driver. During the rotation of the processing tube, the speed of the processing tube is obtained periodically or in real time to obtain the actual speed.

[0081] The actual speed obtained each time or the maximum value of all actual speeds is compared with the set speed range to obtain the matching situation of the actual speed and the set speed range. If the matching situation is different, the subsequent processing method is also different, specifically including dehydrating the dehydration load when the actual speed matches or does not match the set speed range.

[0082] Preferably, upon matching, the dehydration load is dehydrated.

[0083] By adopting this embodiment, when the first eccentricity value of the dehydration load exceeds the first eccentricity threshold, it proves that the eccentricity value of the dehydration load is too large. If the rotation speed of the treatment drum is forcibly increased, the amplitude of the clothing treatment device will be too large or even shifted. By adjusting the dynamic balancing parameters, the rotation speed resonance range of the clothing treatment device is increased, so that when the treatment drum is controlled to rotate, the rotation speed of the treatment drum can reach the increased rotation speed resonance range and the clothing treatment device is not prone to a large amplitude, so that the dehydration load can be at a higher rotation speed, the moisture content can be reduced, and the eccentricity value is reduced. Once the eccentricity value of the dehydration load is reduced to a certain extent, the dehydration load is dehydrated. By adopting this method, there is no need to use a lower rotation speed multiple times to level the dehydration load, which is beneficial to improving the dehydration efficiency of the dehydration load, reducing noise, and thus helping to improve the user experience of the clothing treatment device.

[0084] In a possible embodiment of the present application, adjusting the dynamic balance parameters of the clothes processing equipment includes:

[0085] The damping force of the damper of the treatment cylinder is increased and / or the mass of the balancing weight of the treatment cylinder is increased.

[0086] The damping force of the damper and the mass of the balancing block are related to the maximum eccentric mass of the laundry processing device that causes the processing drum to collide and shift when the processing drum is at various rotation speed values.

[0087] Specifically, the damper may use an electromagnetic damper, and the damping force may be changed by changing the current of the damper; the balancing block may be a water-filled block, and the mass of the balancing block may be different depending on the amount of water injected.

[0088] By adopting this embodiment, a damper with adjustable damping force and / or a balancing block with adjustable mass is used to change the dynamic balance parameters of the clothing processing device, so that the speed resonance range of the clothing processing device is increased, which is convenient, fast and easy to control.

[0089] Optionally, in an implementation of this embodiment, controlling the processing drum to rotate when its theoretical speed is within the speed resonance interval and selectively dehydrating the dehydration load according to the matching of the actual speed of the processing drum with the preset set speed interval includes:

[0090] When the treatment drum rotates at a theoretical speed within the increased speed resonance interval, at least one detection of the actual maximum speed of the treatment drum is performed, so that when the actual maximum speed of the treatment drum does not match the speed interval corresponding to the current detection, the next detection is performed or the dehydration load is dehydrated;

[0091] Among them, the eccentricity value of the dehydration load is also affected during the detection process.

[0092] Specifically, during the detection process, affected by the eccentricity of the dehydration load, the processing drum will maintain a certain speed. At this time, this speed can be used as the actual maximum speed of the processing drum during this detection process. After obtaining the actual maximum speed, the actual maximum speed can be compared with the speed range corresponding to this detection to determine the action to be performed next. Among them, different stages of detection correspond to different speed ranges, and the upper limit value of the speed range corresponding to the later the detection is performed, the larger the upper limit value of the speed range.

[0093] In one embodiment, the detection is performed only once, and when the actual maximum speed matches the speed range, the dehydration is terminated, and when the actual maximum speed does not match the speed range, the dehydration load is dehydrated.

[0094] In another embodiment, the detection is performed at least twice, and when the actual maximum speed matches the speed range, the dehydration is ended, and when the actual maximum speed does not match the speed range, the next detection is performed.

[0095] By adopting the present implementation method, after increasing the speed resonance range, the processing drum can be controlled to reach a higher speed without shifting the clothing processing equipment, so that the dehydration load can have a higher speed, and the eccentricity value is easy to reduce and easy to reduce faster, so that during the next detection, the processing drum reaches a faster speed due to the reduction in the eccentricity value of the dehydration load, thereby gradually increasing the processing drum speed and improving the dehydration effect.

[0096] Optionally, in an implementation of this embodiment, the actual speed includes a first-stage speed value or a second-stage speed value, and the set speed interval includes a first-stage speed interval or a second-stage speed interval;

[0097] When the treatment drum rotates at a theoretical speed within the increased speed resonance range, at least one detection of the actual maximum speed of the treatment drum is performed, so that when the actual maximum speed of the treatment drum does not match the speed range corresponding to the current detection, the next detection is performed or the dehydration load is dehydrated, including:

[0098] Controlling the treatment barrel to rotate in the first stage and obtaining a first stage rotation speed value;

[0099] When the first-stage speed value does not match the first-stage speed interval, the dehydration load is dehydrated, and when the first-stage speed value matches the first-stage speed interval, the dehydration is ended; or when the first-stage speed value does not match the first-stage speed interval, the dehydration load is dehydrated, and when the first-stage speed value matches the first-stage speed interval, the processing drum is controlled to perform a second-stage rotation and obtain a second-stage speed value, so as to dehydrate the dehydration load according to the matching situation between the second-stage speed value and the second-stage speed interval.

[0100] The maximum rotation speed value that the processing drum can reach in the first stage is smaller than the maximum rotation speed value that the processing drum can reach in the second stage, and the maximum value of the first stage rotation speed interval is smaller than the maximum value of the second stage rotation speed interval.

[0101] For ease of understanding, the stages referred to in this embodiment are the number of detections in the foregoing text. For example, the first stage is the first detection execution, the second stage is the second detection execution, and so on.

[0102] With this implementation, since the eccentricity value of the dehydration load is relatively large, by setting the first stage or the first stage and the second stage, the dehydration load is first driven to rotate to reduce the eccentricity value of the dehydration load, and then the rotation speed of the processing drum is used to determine whether the dehydration load can be subsequently dehydrated. This is beneficial to maximally reduce the eccentricity value of the dehydration load, thereby making it easy to reduce the eccentricity value of the dehydration load to below the first eccentricity threshold, which helps to improve the dehydration efficiency.

[0103] Optionally, in an implementation of this embodiment, the method further includes:

[0104] If the processing drum is controlled to rotate in the second stage, the second stage is executed at least once, and when the second stage is executed multiple times, the second stage rotation speed range corresponding to the second stage to be executed next increases.

[0105] It should be noted that when the second stage is executed multiple times, the maximum rotation speed that the processing barrel can reach in the second stage executed next time is higher than the maximum rotation speed in the second stage executed this time.

[0106] By adopting this implementation method, the second stage can be repeatedly executed, and each time the second stage is repeated, the speed range of the second stage will increase, which is beneficial to reduce the number of repetitions of the second stage while reducing the eccentricity value of the dehydration load.

[0107] Optionally, in an implementation of this embodiment, before controlling the processing drum to rotate in the second stage and obtaining the second stage speed value, so as to dehydrate the dehydration load according to the matching of the second stage speed value and the second stage speed range, the method further includes:

[0108] Obtaining a first weight of the dehydrated load before the first stage and a second weight of the dehydrated load before the second stage;

[0109] If the first weight does not exceed the second weight, the dynamic balancing parameters adjusted before and during the first stage are maintained;

[0110] If the first weight exceeds the second weight, the dynamic balancing parameter is adjusted to an initial value.

[0111] That is to say, if the first weight does not exceed the second weight, it means that the moisture content of the dehydration load has not been reduced in the first stage and the weight of the dehydration load has increased. At this time, the eccentricity value of the dehydration load may not change or even become larger, so the dynamic balance parameter still needs to be adjusted. When the first weight exceeds the second weight, it means that the moisture content of the dehydration load has been reduced in the first stage, which naturally reduces the eccentricity value of the dehydration load. Resetting the dynamic balance parameter at this time is conducive to verifying in the second stage whether the rotation speed of the treatment drum can be increased to a speed that will not cause a drum collision when the dynamic balance parameter is at the initial value.

[0112] Using this implementation method, the first weight exceeds the second weight, which proves that the weight of the dehydration load after the first stage is reduced, and the corresponding eccentricity value will also be reduced. At this time, the dynamic balance parameters are reset, which is beneficial for the processing drum to reach a higher rotation speed in the second stage, thereby further reducing the eccentricity value of the dehydration load.

[0113] Optionally, in an implementation of this embodiment, the method further includes:

[0114] If the first-stage speed value exceeds the first-stage speed interval, it is determined that the first-stage speed value does not match the first-stage speed interval, then the processing drum is controlled to slow down to dehydrate the dehydration load;

[0115] If the first-stage speed value does not exceed the first-stage speed range, it is determined that the first-stage speed value matches the first-stage speed range, then the processing drum continues to be controlled to perform the first-stage rotation and the first-stage speed value is re-obtained until the first-stage speed value is within the first-stage fluctuation range and lasts for the first time, thereby ending the dehydration process.

[0116] Among them, the speed value of one stage exceeds the speed range of one stage, which proves that the speed value of one stage is greater than the maximum value of the speed range of one stage, which also proves that the eccentricity value of the dehydrated load has reached the situation where it can rotate at high speed. Dehydrating the dehydrated load can ensure the speed during the dehydration process, thereby ensuring that the moisture content of the dehydrated load meets the standard after dehydration.

[0117] If the first-stage speed value does not exceed the first-stage speed range, it proves that the first-stage speed value is within the first-stage speed range, which also proves that the eccentricity value of the dehydration load is still relatively large and a higher speed cannot be reached.

[0118] With this implementation, if the first-stage speed value exceeds the first-stage speed interval, it proves that in the first stage, the eccentricity value of the dehydration load has been reduced to a certain extent. At this time, the dehydration load is dehydrated, which is easy to ensure the dehydration effect and reduce the moisture content of the dehydration load after dehydration, thereby improving the user experience of the clothing processing device. If the first-stage speed value does not exceed the first-stage speed interval, it proves that the eccentricity value of the dehydration load cannot be reduced to a certain extent, and the dehydration process ends.

[0119] Optionally, in an implementation of this embodiment, according to the matching of the first-stage speed value and the first-stage speed interval, controlling the processing drum to rotate in the second stage and obtaining the second-stage speed value, so as to dehydrate the dehydration load according to the matching of the second-stage speed value and the second-stage speed interval, including:

[0120] If the first-stage speed value exceeds the first-stage speed interval, the processing drum is controlled to slow down, and the processing drum is controlled to rotate in the second stage to obtain the second-stage speed value. If the second-stage speed value exceeds the second-stage speed interval, the processing drum is controlled to slow down to dehydrate the dehydration load. If the second-stage speed value does not exceed the second-stage speed interval, the processing drum is continued to be controlled to rotate in the second stage and the second-stage speed value is re-obtained until the second-stage speed value is within the second-stage fluctuation range and lasts for the second time, and the dehydration process ends;

[0121] If the first-stage speed value does not exceed the first-stage speed range, the processing drum continues to be controlled to rotate in the first stage and the first-stage speed value is re-obtained until the first-stage speed value is within the first-stage fluctuation range and lasts for the first time, thereby terminating the dehydration process.

[0122] The principle of the second stage is the same as that of the first stage and will not be described in detail.

[0123] With this implementation method, the second stage is the same as the first stage. Compared with executing only the first stage, executing the second stage more easily reduces the eccentricity value of the dehydration load, thereby reducing the eccentricity value of the dehydration load to a certain extent with a greater probability, so that the dehydration load can be dehydrated normally, and it is easy to ensure the dehydration effect, reduce the moisture content of the dehydration load after dehydration, and thus improve the user experience of the clothing processing equipment.

[0124] Optionally, in an implementation of this embodiment, controlling the processing cylinder to rotate in the first stage includes:

[0125] Controlling the driver of the treatment drum to start, and obtaining a first maximum drum rotation speed and a first minimum drum rotation speed of the treatment drum, or obtaining a first maximum torque and a first minimum torque of the driver, each time the treatment drum rotates a first number of times;

[0126] Calculating a difference between a first maximum drum speed and a first minimum drum speed, or calculating a difference between a first maximum torque and a first minimum torque, to obtain a first difference;

[0127] If the difference between the first difference value and the first difference value calculated last time does not exceed the preset first difference threshold, the processing tube is controlled to increase its speed; otherwise, the processing tube is controlled to stop increasing its speed.

[0128] The first number of turns is preferably 1 turn, but may also be other numbers of turns, such as 2 turns or 3 turns, which is not specifically limited in this embodiment.

[0129] The first difference threshold is set according to actual conditions, such as 10 revolutions, 15 revolutions, etc., and this embodiment does not specifically limit this. The first difference threshold is mainly used to monitor whether the processing drum can continue to increase its speed.

[0130] Controlling the treatment drum to rotate in the second stage includes:

[0131] Controlling the driver of the treatment drum to start, and obtaining the second maximum drum rotation speed and the second minimum drum rotation speed of the treatment drum, or obtaining the second maximum torque and the second minimum torque of the driver, every time the treatment drum rotates a second number of times;

[0132] Calculating the difference between the second maximum drum speed and the second minimum drum speed, or calculating the difference between the second maximum torque and the second minimum torque to obtain a second difference;

[0133] If the difference between the second difference value and the second difference value calculated last time does not exceed the preset second difference threshold, the processing drum is controlled to increase its speed; otherwise, the processing drum is controlled to stop increasing its speed.

[0134] By adopting this implementation method, by monitoring the rotation speed of the processing drum or the torque of the driver, it is controlled whether the processing drum continues to increase in speed, which makes it easy to control the stability of the processing drum during rotation, thereby making it less likely to cause the drum to collide or the clothing processing equipment to shift, which helps to improve the user experience of the clothing processing equipment.

[0135] Optionally, in an implementation of this embodiment, dehydrating the dehydrated load includes:

[0136] Controlling the start of the driver of the treatment cylinder;

[0137] When the rotation speed of the processing drum is within a fluctuation range, the driver is controlled to drive the processing drum to increase the speed at a target acceleration;

[0138] Every time the processing drum rotates a third number of times, a third maximum drum rotation speed and a third minimum drum rotation speed of the processing drum are obtained;

[0139] calculating a difference between a third maximum drum rotation speed and a third minimum drum rotation speed to obtain a third difference;

[0140] Calculating the change slope of the third difference and the change slope of the rotation speed of the treatment drum;

[0141] If the change slope of the third difference does not exceed the change slope of the rotation speed, the processing tube is controlled to continue to increase the speed; otherwise, the processing tube is controlled to stop increasing the speed.

[0142] With this implementation, when dehydrating, the speed of the processing drum is first increased to a relatively stable range, and then the speed of the processing drum is gradually increased at the target acceleration, which makes it less likely for the drum to collide or the clothing processing device to shift. At the same time, during the speed increase process, the speed of the processing drum is used to monitor the stability of the clothing processing device, further reducing the probability of drum collision and displacement.

[0143] Optionally, in an implementation of this embodiment, as Figure 2 As shown, the method also includes:

[0144] S200: If the second eccentricity value of the dehydration load exceeds the first eccentricity threshold, the first eccentricity threshold is increased to obtain a second eccentricity threshold.

[0145] The second eccentricity threshold is greater than the second eccentricity value.

[0146] S202. Using the second eccentricity threshold as a limiting condition for the processing drum to drive the dehydration load to rotate, so that the processing drum can drive the dehydration load to rotate.

[0147] S204: Acquire the eccentricity value of the dehydration load to obtain a first eccentricity value.

[0148] S206: If the first eccentricity values ​​exceed the first eccentricity threshold value within the preset third time period, the dynamic balance parameters of the clothing processing device are adjusted to increase the rotation speed resonance range of the clothing processing device; otherwise, a preset dehydration program is executed.

[0149] The preset dehydration program includes a dehydration program executed when the eccentricity value of the dehydration load does not exceed a first eccentricity threshold.

[0150] By adopting this implementation method, the first eccentricity value is increased, so that the processing drum can drive the dehydration load greater than the first eccentricity value to rotate, thereby quickly reducing the eccentricity value of the dehydration load, avoiding the inability to trigger the clothing processing equipment to drive the dehydration load to rotate due to the eccentricity value of the dehydration load being too large, and helping to quickly reduce the eccentricity value of the dehydration load.

[0151] An embodiment of the present application also provides a method for controlling a clothing processing device, including the above method.

[0152] An embodiment of the present application also provides a clothing processing device, which uses the above method when dehydrating the clothing processing device.

[0153] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

[0154] In a specific implementation of the embodiment of the present application, the dehydration control method includes the following processing steps:

[0155] During the dehydration process, heavy clothes are difficult to spread evenly or their own uneven water absorption leads to large eccentricity, making it difficult to increase the speed of dehydration. If this type of load needs to be dehydrated, the eccentricity threshold of the speed control needs to be amplified (that is, for clothes whose eccentricity exceeds the first eccentricity threshold, the first eccentricity threshold needs to be amplified). After amplifying the eccentricity threshold, the heavy clothes are prone to shifting during the speed increase process. After multiple tests and verifications, the speed range where the shift occurs is the resonant speed range of the whole machine. The vibration is large at the same eccentricity in this speed range. If the eccentricity threshold is amplified, the vibration will be amplified synchronously. When the vibration state reaches the limit state, the drum washing machine will be shifted. If the washing machine shifts, it will cause safety problems during the use of the washing machine, such as damage to the prototype due to impact, leakage caused by the pulling and disconnection of the water pipe, and other problems.

[0156] The low-speed resonance area of ​​a general drum washing machine is between 150rpm and 300rpm. During the dehydration process, when heavy clothes or loads absorb water unevenly, the eccentricity distributed in the drum is large and not a fixed and unique eccentricity (that is, the position and eccentricity of the clothes will change during the rotation process, so the eccentricity of the clothes is not fixed and unique). The eccentricity will be different at the speed point of its displacement (that is, the eccentricity of the clothes will continue to change, resulting in different eccentricities corresponding to different displacement speeds), and the moisture content of this type of load will drop significantly after running at a low speed, and the redistributed eccentricity will no longer shift when dehydrating again.

[0157] Generally, the eccentricity of clothes needs to be detected when the drum washing machine is at a safe and low speed. After the same eccentricity value is detected and fed back at this stage, the speed point where the displacement occurs is different due to the water loss of the load during the speed increase process or the different area occupied by the clothes in the drum. If the worse state of this type of clothes is set to not allow the speed increase dehydration at a safer speed, the chance of speed increase of the dehydration of this type of clothes is reduced, affecting the speed increase of dehydration. At a lower dehydration speed, the moisture content of the clothes will become higher, affecting the user experience.

[0158] At an appropriate rotation speed, the weight or eccentricity of heavy clothes after losing water will be greatly reduced. Based on the above characteristics, a washing machine with variable balance parameters is designed. By adjusting the components related to dynamic balance such as counterweight or damping, the resonance range of the current washing machine is temporarily transitioned. For example, the original resonance range of 150rpm~300rpm is transitioned to 200rpm~350rpm. At this time, a large eccentric state of clothes is allowed to be dehydrated at a minimum of 200rpm to 350rpm.

[0159] The above execution process takes the same clothing as an example:

[0160] First, the clothes are unfolded before dehydration, and the clothes are adjusted to the eccentricity threshold (second eccentricity threshold) that can be increased in speed. In this solution, the threshold that can be increased in speed will be enlarged to the eccentricity threshold when 350rpm is not shifted, increasing the situation of rapid dehydration. If the eccentricity threshold is controlled according to the minimum speed of 150rpm, the leveling process needs to be repeated, which is time-consuming, and the probability of forming an eccentricity value within the eccentricity threshold of the minimum speed of 150rpm is extremely low, resulting in long dehydration time and low dehydration efficiency.

[0161] The process of adjusting the clothing state to reach the first eccentricity threshold sets a maximum trial time. If the clothing state still cannot increase the speed of dehydration within this time, the dynamic balance parameters are adjusted and the speed increase process is detected and controlled;

[0162] The dynamic balancing parameters refer to the extreme eccentric mass of the impact cylinder when it is displaced at each speed point. Changing the damping force of the system or the mass of the balancing block will affect the change of the dynamic balancing parameters.

[0163] This scheme example only changes the dynamic balance parameters by changing the damping force of the damper. The damper on the washing machine system uses an electromagnetic damper with variable damping. When the damper changes its current signal, the magnitude of the damping force changes in direct proportion to the magnitude of the current.

[0164] If the damping force increases, the low-speed resonance range of the system will jump upward, and the low-speed resonance speed point will increase. If this speed point increases, the clothes can be dehydrated at this speed, the state of the clothes can be changed, and after the clothes are redistributed, the eccentric state can be reduced to the eccentricity value that can increase the speed.

[0165] Because the damping force of the damper needs to be restored to its original state before speeding up again, and the vibration noise at high speed will increase due to the increase in damping force, after dehydration at low speed, the damping force needs to be restored before dehydration.

[0166] The adjusted dynamic balance parameters only allow the current clothes to be dehydrated. If there is an abnormal scene such as power failure or pause, the original damping force parameters will be restored;

[0167] During the speed-up process of the clothes preparation, the difference between the maximum and minimum values ​​of the torque or speed within each rotation is determined. The determination process is as follows Figure 3 The speed increase and speed maintenance stage of stage b shown in the figure, the speed increase or maintenance stage threshold in this stage, set a speed safety interval (i.e., the first stage speed interval), during the operation, if it meets the interval, it will continue to run until S1 and continue to run until the maximum time set is over, if it does not meet the interval, it will reduce the speed at any time point;

[0168] like Figure 3 If the b stage fails to run successfully and the maximum running time of the stage is reached, that is, the speed of the treatment drum is always in the speed range of the first stage and lasts until the maximum time ends, it is considered that the b stage has not run successfully, which means that the eccentricity of the type of clothing far exceeds the maximum limit of the washing machine, and the dehydration process is terminated;

[0169] like Figure 3 If the b stage in the above process is successfully executed, that is, the speed exceeds the speed range of the first stage, then Figure 3 The c stage in the process is executed, and before the speed increase in the c stage, the load status needs to be confirmed again;

[0170] At the beginning of stage c, the state and weight of the clothes are detected. If the weight of the clothes in stage c is less than the weight of the clothes in stage b, the damper parameters changed before and during stage b are restored to the parameters of the original state; if the weight of the clothes in stage c is greater than or equal to the weight of the clothes in stage b, the damping force parameters of the damper changed before and during stage b and the current control current parameters of the damper are maintained;

[0171] Similarly, when executing stage c, the speed increase and speed maintenance stages S2 both detect the difference between the maximum and minimum torque values ​​within each rotation. The threshold of the speed increase or maintenance stage in this stage, the threshold of the speed safety interval (that is, the second stage speed interval) is higher than the threshold of stage b. If it meets the threshold interval of this stage, it needs to be maintained until the maximum speed setting time ends. If it does not meet the threshold, the speed is reduced to 0. After the longest trial time of this stage ends, the d stage is run;

[0172] The difference between stage d and stage b\c is that in the speed maintenance stage S3, the speed is not a constant speed, but increases at a small acceleration (the optimal acceleration range is less than 5rpm / s). The detection method in this stage is to detect the maximum and minimum difference of the speed every 5rpm;

[0173] The difference between the interval speeds is counted and the change slope of the difference is calculated. If the calculated slope is less than or equal to the change slope of the speed, the speed will continue to increase until the change slope of the difference is greater than the change slope of the speed.

[0174] In this embodiment, within the scope allowed by the structure, the speed-up and dehydration control of the load is performed as much as possible to fully dry out the water in the load.
