Description

Technical Field

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

[0002] Most fabric processing equipment adopts the traditional dehydration method, which adopts a one-stage speed increase. When the eccentricity of the clothes in the barrel is too large, the speed increases too fast and it is easy to hit the box, resulting in a poor user experience. After the dehydration hits the safety bar, the correction generally only adopts a single correction method of water storage correction. The occasional collision with the bar for non-extremely eccentric loads (or loads that are not prone to displacement) will trigger the water storage correction, while the extremely eccentric load is prone to multiple water storage corrections, resulting in a waste of water resources. Summary of the invention

[0003] The embodiment of the present application provides a dehydration control method and a fabric processing device, which adopts a segmented speed-up method during the dehydration process, and determines whether the current eccentric gear is prone to displacement and whether it needs to enter water storage and correction by detecting whether the number of times the rod is hit exceeds the limit in the first and second speed-up stages, that is, the dehydration operation state of the load in the barrel at this time (the hit rod, displacement). If it does not exceed the limit, the next stage of speed increase is carried out to stabilize the dehydration state of the prototype, so that it can stably pass the resonant speed and reduce the probability of displacement when it is increased to a higher speed. At the same time, in the corresponding speed-up stage, the water storage and correction program is only executed when the number of times the safety rod is hit exceeds the preset value, which means that in many cases, unnecessary water storage and correction can be avoided, thereby saving water resources.

[0054] Background

[0055] At present, most fabric processing equipment adopts the traditional dehydration method, which adopts a one-stage speed increase. When the eccentricity of the clothes in the barrel is too large, the speed increase is too fast and it is easy to hit the box, resulting in poor user experience; after the dehydration hits the safety bar, the correction generally only adopts a single correction method of water storage correction. The occasional collision with the bar for non-extremely eccentric loads (or loads that are not prone to displacement) will trigger the water storage correction, while the extremely eccentric load is prone to multiple water storage corrections, resulting in a waste of water resources.

[0056] By testing the rotation speed of the traditional dehydration method when the impact rod is triggered under different eccentric weights and positions, it is found that the rotation speed of the impact rod when the load in the barrel is in a low and medium eccentric state is mostly distributed in 70rpm-90rpm. It is speculated that when the dehydration speed is 70rpm-90rpm, the barrel body is at the resonance point and the probability of hitting the rod is higher. Therefore, it is believed that the rotation speed when the impact rod is used can be used to distinguish the eccentricity in the barrel at this time (*the approximate relationship between the eccentricity gear and the weight).

[0057] Eccentric gear Eccentric mass / kg Low eccentricity ≤1.0 Middle eccentricity 1.0-1.2 High eccentricity ＞1.2

[0058] By testing the number of times the speed V hits the bar in each eccentric state when the speed V increases from 0 to V1 and maintains it, it is found that the number of times the speed V1 has different eccentricities: when the eccentricity is greater than 1.0kg, more times of hitting the bar / continuous hitting the bar will occur; when the eccentricity is ≤1.0kg, the number of hitting the bar is ≤4 times. It is verified that (the first distinction condition) can be verified by detecting whether the number of hitting the bar at the dehydration speed V1 is greater than 4 times, and the eccentricity of the load in the barrel can be preliminarily judged. The eccentricity of the load in the barrel can be distinguished as low, medium, medium and high. It can basically be determined that the dehydration can be successful when the eccentricity is ≤1.0kg (low eccentricity). That is, it means that the load in the barrel can be considered to be initially distinguished with 1.0kg as the limit for the first time. Here, it can be determined that there is no risk of hitting the box and hitting the bar displacement for low eccentricity (less than or equal to 1.0), while the situation between 1.0kg-1.2kg is more complicated, and further judgment is needed to determine whether there is a risk.

[0059] However, at the speed of V1, it is not possible to make a more detailed distinction (except for low eccentricity) of the eccentric mass that can be successfully dehydrated. In order to make a more detailed distinction and judgment between medium and high eccentricities, the load mass that can be successfully and safely dehydrated without obvious displacement after a few / 0 slight collisions with the box body is judged {that is, under the premise of medium and high eccentricity, there may be a few or few or even no collisions with the box body. In this case, the box body may have a slight shake and produce a very small displacement. It is believed that the eccentric mass under this eccentricity can be classified as a load mass that can be successfully and safely dehydrated without risk}, so as to improve the dehydration success rate. By testing the number of times the speed V hits the rod in each eccentric state when the speed V is increased from 0 to V2 and maintained, it is found that the number of times different eccentricities hit the rod at the speed of V2 is different: when the eccentricity is greater than 1.2kg, the rod will continue to hit; when the eccentricity is 0kg≤eccentricity≤1.2kg, the number of times the rod hits the rod is ≤2 in most cases. It has been verified that (the second distinguishing condition) the eccentricity of the load in the barrel can be further judged by detecting whether the number of times the bar is hit at the dehydration speed V2 is greater than 2 times, and the eccentricity of the load in the barrel can be distinguished as low, medium and high. It can basically be determined that dehydration cannot be successful when the eccentricity is greater than 1.2kg (high eccentricity).

[0060] According to the above speed V1 and V2 test conditions combined with two distinguishing conditions, two speed maintenance tests are set to test the dehydration stability and operation of each gear eccentricity. Through testing, it is found that the medium and high eccentricity will run more smoothly when the speed is increased to about 140-300rpm. Therefore, the stable speed is set to V3. It can be considered that the medium and high eccentricity can run stably at the speed of V3. After that, the speed increase is conducive to reducing the risk of displacement caused by too fast speed increase.

[0061] Based on the above test conditions, if Figure 1 and Figure 2 As shown, a first aspect of an embodiment of the present application provides a dehydration control method for a fabric processing device, wherein the fabric processing device has a dehydration program for dehydrating a load, wherein the device generates resonance when the dehydration speed is in a resonance speed interval under the dehydration program, wherein in an embodiment of the present application, the dehydration program includes a first speed-up phase and a second speed-up phase that are successively executed, wherein a first target speed value of the first speed-up phase is lower than a minimum value of the resonance speed interval, and a second target speed value of the second speed-up phase is higher than a maximum value of the resonance speed interval;

[0062] Dehydration control methods include:

[0063] Under the dehydration program, the number of times the safety bar of the fabric processing device is hit in the first speed-up stage and the second speed-up stage is obtained, and whether to execute the water storage correction program is determined according to the number of times the safety bar is hit;

[0064] If the number of times the safety bar is hit is greater than the maximum permissible number of hits corresponding to the current speed-up stage, the water storage correction procedure is executed;

[0065] Otherwise, execute the next speed-up phase.

[0066] In the embodiment of the present application, a segmented speed-up method is adopted during the dehydration process. By detecting whether the number of times the bar is hit exceeds the limit in the first and second speed-up stages, that is, the dehydration operation state of the load in the barrel at this time (bar hit, displacement), it is judged whether the current eccentric gear is prone to displacement and whether it is necessary to enter water storage and correction; if it does not exceed the limit, the next stage of speed increase is carried out to stabilize the dehydration state of the prototype, so that it can stably pass the resonant speed and reduce the probability of displacement when it is increased to a higher speed. At the same time, in the corresponding speed-up stage, the water storage and correction program is executed only when the number of times the safety bar is hit exceeds the preset value, which means that in many cases, unnecessary water storage and correction can be avoided, thereby saving water resources.

[0067] That is, by dividing the dehydration program into two stages, in which the first target speed of the first stage is lower than the minimum value of the resonance speed range, and the second target speed of the second stage is higher than the maximum value of the resonance speed range, it can be ensured that the fabric processing equipment will not be in the resonance speed range during these two speed-up stages, thereby avoiding equipment damage caused by resonance. By monitoring the number of times the safety bar is hit in the first and second speed-up stages and comparing it with the maximum allowable number of hits, it can be intelligently determined whether the water storage correction program needs to be executed. This method can reduce unnecessary correction operations, improve dehydration efficiency, and save water resources.

[0068] That is, in the embodiment of the present application, the speed-up phase of the dehydration program is cleverly controlled to avoid the resonant speed range, thereby improving the dehydration efficiency, protecting the equipment, optimizing the user experience, and improving the overall safety and economy.

[0069] Further, in some possible implementations, the eccentric state of the load includes a low eccentric state, a medium eccentric state and a high eccentric state, wherein

[0070] The number of times the load in the low eccentricity state hits the safety bar in the first speed-up stage is less than the first preset impact value, and the number of times the load in the medium eccentricity state and the high eccentricity state hits the safety bar in the first speed-up stage is greater than or equal to the first preset impact value;

[0071] The number of times the load in the low eccentricity state and the medium eccentricity state hits the mounting rod in the second speed increase stage is less than the second preset impact value, and the number of times the load in the high eccentricity state hits the safety rod in the second speed increase stage is greater than or equal to the second preset impact value.

[0072] That is, in the embodiment of the present application, by setting a specific impact number threshold (a first preset impact value and a second preset impact value), the eccentric state of the load can be detected more accurately, so that corresponding dehydration control measures can be taken. According to the impact number of loads with different eccentric states at different speed-up stages, the dehydration strategy can be intelligently adjusted to adapt to loads with different eccentricities and improve the dehydration efficiency. By distinguishing the eccentric state and taking corresponding correction measures, the impact and wear of the equipment caused by the eccentric load can be reduced, and the service life of the equipment can be extended.

[0073] That is, in the embodiment of the present application, a specific impact number threshold is set to distinguish loads in different eccentric states, and the dehydration strategy is intelligently adjusted according to these states. This method helps to improve dehydration efficiency, reduce equipment wear, save resources, and improve user experience.

[0074] Further, in some possible implementations, when the eccentricity value of the load is less than or equal to the first eccentricity value, the eccentricity state of the load is in a low eccentricity state;

[0075] When the eccentricity value of the load is greater than the first eccentricity value and less than or equal to the second eccentricity value, the eccentricity state of the load is a medium eccentricity state;

[0076] When the eccentricity value of the load is greater than the second eccentricity value, the eccentricity state of the load is a high eccentricity state.

[0077] Preferably, in combination with the above test situation, in some possible implementations, the first preset impact value is 4, and the second preset impact value is 2;

[0078] The first eccentricity value is 1.0kg, and the second eccentricity value is 1.2kg;

[0079] The first target speed ranges from 55 rpm to 70 rpm, and the second target speed ranges from 90 rpm to 120 rpm;

[0080] The resonance speed range is between 70rpm and 90rpm.

[0081] That is, by setting specific eccentricity values ​​(first eccentricity value and second eccentricity value) and preset impact values, the low, medium and high eccentricity states of the load can be clearly distinguished. This clear distinction helps to take more precise control measures. The setting of the first target speed and the second target speed avoids the resonant speed range, which helps to reduce vibration and noise during the dehydration process and protect the equipment from damage caused by resonance. By setting a specific impact number threshold, unnecessary water storage correction procedures can be reduced, thereby saving water resources, especially in the low eccentricity state. Dehydration at a non-resonant speed can improve dehydration efficiency because the equipment can operate without causing additional vibration, reducing energy consumption and dehydration time.

[0082] Further, in some possible implementations, the maximum permissible number of impacts in the first speed-up stage is greater than the maximum permissible number of impacts in the second speed-up stage, and the first target speed in the first speed-up stage is less than the second target speed in the second speed-up stage; or

[0083] The maximum permissible number of impacts in the first speed-up stage is 4, the maximum permissible number of impacts in the second speed-up stage is 2, the first target speed in the first speed-up stage is in the range of 55rpm-70rpm, and the second target speed in the second speed-up stage is in the range of 90rpm-120rpm;

[0084] The resonance speed range is 70rpm-90rpm.

[0085] Further, in some possible implementations, the dehydration control method further comprises:

[0086] In the first speed-up phase, the speed is increased at an acceleration rate a1 and maintained for a first preset time when the speed reaches a first target speed;

[0087] In the second speed-up phase, the speed is increased at the acceleration a1 and maintained for a second preset time when the speed reaches the second target speed;

[0088] The first preset duration is greater than the second preset duration.

[0089] In the embodiment of the present application, by setting different preset durations for the two speed-up stages, the dehydration process can be controlled more meticulously, especially the dehydration effect of the load can be optimized at different speed-up stages. The longer first preset duration allows more time to stabilize the load and dehydrate in the low eccentricity state, while the shorter second preset duration is suitable for the medium and high eccentricity states to reduce the maintenance time at a higher speed that may cause resonance. At the same time, since the first target speed is lower than the minimum value of the resonance speed interval, maintaining a longer time in the first speed-up stage can reduce the risk of resonance. The second target speed of the second speed-up stage is higher than the maximum value of the resonance speed interval, so the maintenance time is shorter to quickly pass through the speed interval that may cause resonance. In addition, allowing more time for dehydration in the first speed-up stage can more effectively remove water at a lower speed, especially when the load eccentricity is small, by reducing the maintenance time in the second speed-up stage, the wear and failure risk of the equipment at a higher speed can be reduced, especially when the load eccentricity is large, balancing the dehydration effect and energy consumption between the two stages, and reducing energy consumption without affecting the dehydration effect.

[0090] Further, in some possible implementations, the dehydration control method further comprises:

[0091] After executing the water storage correction procedure, re-execute the dehydration procedure.

[0092] Further, in some possible implementations, the dehydration control method further comprises:

[0093] Under the dehydration program, obtain the total number of times the safety bar is hit;

[0094] If the total number of times the safety bar is hit is greater than or equal to the preset number of times, an alarm message is output, and the fabric processing device is controlled not to perform the water storage deviation correction procedure;

[0095] and / or

[0096] Under the dehydration program, obtain the total number of times the water storage correction program is executed;

[0097] If the number of executions of the water storage deviation correction program is greater than or equal to the preset execution number, an alarm message is output, and the fabric processing device is controlled not to perform the water storage deviation correction program.

[0098] It should be noted that the number of times the safety bar is hit is directly related to the degree of eccentricity of the dehydration barrel and the stability during the dehydration process. If the number of hits is too many, it may mean that the load is seriously eccentric or there are other problems, which need to be dealt with in time to avoid equipment damage. By monitoring the number of hits of the safety bar, preventive maintenance or adjustments can be performed before the problem becomes serious, reducing the risk of sudden failures. Outputting alarm information can promptly notify users of possible problems in the dehydration process, allowing users to take appropriate measures, such as rebalancing the load or checking the status of the equipment. At the same time, monitoring the number of hits can also provide manufacturers with data for improving product design and optimizing dehydration control algorithms.

[0099] That is, by adding a monitoring and alarm mechanism for the number of times the safety bar hits, the embodiment of the present application aims to reduce the risk of equipment damage, improve the safety and reliability of the dehydration process, and at the same time enhance the user experience and the intelligence level of the equipment. This method helps to reduce maintenance costs and provide data support for the continuous improvement of products.

[0100] It should also be noted that the number of executions of the water storage correction program can reflect the severity of the load eccentricity during the dehydration process. If the correction program needs to be executed frequently, it may mean that the dehydration control method needs to be adjusted or there is a problem with the equipment. At the same time, frequent water storage correction not only consumes additional water resources, but may also increase the energy consumption and wear of the equipment. By setting the preset number of executions, unnecessary waste of resources can be avoided. If the correction program is executed too many times, it may be caused by severe load eccentricity or equipment failure. Outputting an alarm message can remind the user or maintenance personnel to check to prevent equipment damage. The alarm message can guide the user to redistribute the laundry load or take other measures to reduce the number of executions of the eccentricity and correction programs.

[0101] That is, in the embodiment of the present application, by increasing the monitoring and alarm mechanism for the number of executions of the water storage correction program, the purpose is to improve dehydration efficiency, save resources, protect equipment, and enhance user experience and the intelligence level of the equipment. This method helps to reduce maintenance costs and provide data support for the continuous improvement of products.

[0102] Furthermore, in some possible implementations, the dehydration procedure further includes a third speed-up stage and a fourth speed-up stage;

[0103] Dehydration control methods also include:

[0104] The control device executes the third speed-up stage at the acceleration a3, and maintains the operation for the third preset time when the third target speed is reached, and after the third preset time is completed, the control device executes the fourth speed-up stage at the acceleration a4, and maintains the operation for the fourth preset time when the fourth target speed is reached;

[0105] Among them, the acceleration a4 is smaller than the acceleration a3.

[0106] Preferably, the acceleration a3 of the third acceleration stage is the same as the accelerations of the first acceleration stage and the second acceleration stage.

[0107] In the embodiment of the present application, by reducing the acceleration in the fourth speed-up stage, the speed-up speed can be controlled to prevent the motor from overheating.

[0108] It should be noted that the reason why the third speed-up stage is set in the embodiment of the present application and the acceleration of the third speed-up stage is set to be greater than the acceleration of the fourth speed-up stage is to quickly cross the secondary resonance speed that may cause the drum to jump in the third speed-up stage {the above-mentioned 70rpm-90rpm is the first resonance speed that may cause the drum to jump}. The reason why the fourth speed-up stage is set is that the target speed of the third stage is relatively low, and the moisture content of the clothes after dehydration does not reach the specified value when maintaining this speed, so it is necessary to speed up to the fourth speed-up stage with a higher speed so that the drum can be dehydrated at a higher speed. However, if a large acceleration is maintained for a long time, the motor will heat up faster, the motor will consume more power and have greater losses, which can easily cause the motor to overheat, so it is necessary to set the acceleration of the fourth speed-up stage to be smaller.

[0109] Preferably, in some possible implementations, the third speed-up stage has a third target speed, and the fourth speed-up stage has a fourth target speed;

[0110] The third target speed is in the range of 140 rpm to 300 rpm, the fourth target speed is in the range of 550 rpm to 900 rpm, and the fourth target speed is greater than the maximum value of the second resonance speed;

[0111] The acceleration a1 value range is between 0.5 revolutions per square second and 0.8 revolutions per square second, and the acceleration a2 value range is between 0.15 revolutions per square second and 0.4 revolutions per square second.

[0112] It is worth noting that, through the above test, it can be seen that the medium and high eccentricity loads will run more smoothly when the speed is increased to about 140rpm-300rpm. Therefore, the stable speed of the third speed-up stage is set between 140rpm-300rpm. It can be considered that the medium and high eccentricity loads can be in a stable operating state at a speed of 140rpm-300rpm. After that, the speed increase is conducive to reducing the risk of displacement caused by too fast speed increase.

[0113] Specifically, in order to more clearly understand the control logic of the dehydration control method provided in this embodiment, Figure 2 To explain in detail:

[0114] like Figure 2 As shown: After the fabric treatment equipment has finished draining and started the dehydration process, the speed increase process is divided into 4 speed increase stages and 2 tests are added:

[0115] The first stage: distinguish the low eccentricity and low-medium eccentricity gear loads, whose running state is relatively stable, and judge whether they meet the conditions for entering the second stage, so that they maintain a stable state and enter the second stage of speed increase;

[0116] If the eccentricity is in the medium-high eccentricity or high eccentricity gear, its running state is unstable. It is determined that the eccentricity exceeds the eccentricity range that can be corrected by speed at this time, and water storage correction is entered.

[0117] Acceleration a1, rotation speed V:0→V1, V1 is maintained for 10s, during which the number of times the collision is detected is >4?

[0118] Determine whether its status is suitable for entering the second stage of speed increase:

[0119] If the number of hits is greater than 4, water storage and deviation correction will be initiated;

[0120] If the number of hits is ≤4, the vehicle will enter the second stage of speed increase;

[0121] The second stage: distinguish the relatively stable eccentricity value in the middle eccentricity gear (the middle eccentricity here is 1.0-1.2kg), judge whether it meets the conditions for entering the third stage, and keep it stable to enter the third stage of speed increase;

[0122] If the eccentricity is a relatively unstable eccentricity value in the middle eccentricity gear, its running state is unstable. It is determined that the eccentricity exceeds the eccentricity range that can be corrected by speed at this time, and water storage correction is entered.

[0123] Acceleration a1, rotation speed V: V1→V2, V2 is maintained for 5s, during which the number of times the collision is detected is >2?

[0124] Determine whether its status is suitable for entering the third stage of speed increase:

[0125] If the number of hits is greater than 2, the system will enter water storage and deviation correction mode;

[0126] If the number of hits is ≤2, the vehicle will enter the third stage of speed increase;

[0127] The third stage: In order to avoid the sudden change of eccentricity due to excessively fast speed increase after the stable eccentricity has passed the second test, this stage is set to stabilize the eccentricity state again.

[0128] Acceleration a1, speed V: V2→V3, stable running state;

[0129] The fourth stage: acceleration a2, rotation speed V: V3→V4, until V4→0.

[0130] Full journey:

[0131] 1. In order to deal with the sudden eccentricity of the prototype outside the testing stage, set up the whole process of hitting the pole number detection (including the number of hitting the pole in the early stage);

[0132] Is the total number of collisions during the dehydration test ≥ 8?

[0133] Determine whether the status is a fault prompt:

[0134] If the number of water storage corrections is ≤2, the water storage correction will proceed normally;

[0135] If the number of water storage corrections is greater than 2, it indicates a dehydration imbalance fault;

[0136] 2. To reduce unnecessary water waste caused by extreme eccentricity that exceeds the eccentricity range that can be corrected by speed, set up a full-process water storage correction frequency detection.

[0137] Is the number of water storage corrections during the whole dehydration process > 2?

[0138] Determine whether the status is a fault prompt:

[0139] If the number of water storage corrections is ≤2, the fault alarm will not be triggered;

[0140] If the number of water storage corrections is greater than 2, a dehydration imbalance fault is indicated.

[0141] It is worth explaining that the water storage correction program means that the equipment will wash for a few minutes after entering the water, adjust the position of the clothes in the water, and then drain the water and try to dehydrate.

[0142] Furthermore, the second aspect of the embodiment of the present application also provides a fabric processing device, which includes the dehydration control method provided in the first aspect of the embodiment of the present application.
