A dewatering control method for a fabric treatment device and the fabric treatment device itself.

Abstract

This application provides a dewatering control method and fabric processing equipment for a fabric processing device, belonging to the technical field of fabric processing equipment. It employs a segmented speed-up method during the dewatering process. By detecting whether the number of impacts to the safety bar exceeds a limit during the first and second speed-up stages—that is, the dewatering operation status of the load inside the drum at this time—it determines whether the current eccentric gear is prone to displacement and whether water storage correction is necessary. If the limit is not exceeded, the next speed-up stage proceeds, stabilizing the dewatering state of the prototype and enabling it to stably pass the resonance speed, reducing the probability of displacement at higher speeds. Simultaneously, during the corresponding speed-up stage, the water storage correction procedure is only executed when the number of impacts to the safety bar exceeds a preset value. This means that in many cases, unnecessary water storage correction can be avoided, thereby saving water resources.

Description

Technical Field

[0001] This application relates to the field of fabric treatment equipment technology, and more specifically, to a dehydration control method and fabric treatment equipment. Background Art

[0002] Most textile processing equipment uses traditional dewatering methods with a single-stage speed increase. When the clothes in the drum are too eccentric, the speed increase is too fast and it is easy to cause the clothes to hit the drum, resulting in a poor user experience. After the clothes hit the safety bar during dewatering, the correction method usually only uses water storage correction. For non-extremely eccentric loads (or non-displacement loads), occasional hits to the bar will trigger water storage correction, while for extremely eccentric loads, multiple water storage corrections are likely to occur, resulting in waste of water resources. Summary of the Invention

[0003] This application provides a dewatering control method and fabric processing equipment for a fabric treatment device. It employs a segmented speed-up method during the dewatering process. By detecting whether the number of impacts to the safety bar exceeds a limit during the first and second speed-up stages—that is, by assessing the dewatering operation status of the load inside the drum (impact, displacement)—it determines whether the current eccentric gear is prone to displacement and whether water-filling correction is necessary. If the limit is not exceeded, the next speed-up stage proceeds to stabilize the dewatering state of the prototype, enabling it to stably pass the resonance speed and reducing the probability of displacement at higher speeds. Simultaneously, during the corresponding speed-up stage, the water-filling correction procedure is only executed when the number of impacts to the safety bar exceeds a preset value. This means that in many cases, unnecessary water-filling correction can be avoided, thereby saving water resources. Specifically:

[0004] The first aspect of this application provides a dewatering control method for a fabric processing device. The fabric processing device has a dewatering program for dewatering a load. In the dewatering program, the device resonates when the dewatering speed is in the resonant speed range.

[0018] The first target speed ranges from 55 rpm to 70 rpm, and the second target speed ranges from 90 rpm to 120 rpm.

[0019] The resonant speed range is 70rpm-90rpm.

[0020] In the above technical solution, the maximum permissible number of impacts in the first acceleration phase is greater than the maximum permissible number of impacts in the second acceleration phase, and the first target rotational speed in the first acceleration phase is less than the second target rotational speed in the second acceleration phase; or

[0021] The maximum number of permissible impacts during the first acceleration phase is 4, and the maximum number of permissible impacts during the second acceleration phase is 2. The first target speed during the first acceleration phase is 55 rpm-70 rpm, and the second target speed during the second acceleration phase is 90 rpm-120 rpm.

[0022] The resonant speed range is 70 rpm to 90 rpm.

[0024] In the first acceleration phase, the speed is increased by acceleration a1 and maintained for a first preset duration when the speed reaches the first target speed;

[0025] In the second acceleration phase, the speed is increased by acceleration a1 and maintained for a second preset duration when the speed reaches the second target speed;

[0026] The first preset duration is longer than the second preset duration.

[0028] After performing the water storage and correction procedure, the dehydration procedure is performed again.

[0029] In the above technical solutions, the dehydration control method also includes:

[0030] During the dehydration process, the total number of times the safety bar was impacted was obtained;

[0031] If the total number of impacts on the safety bar is greater than or equal to the preset number of impacts, an alarm message will be output, and the fabric processing equipment will be controlled not to perform the water storage and correction procedure.

[0032] and / or

[0033] Under the dehydration process, obtain the total number of times the water storage correction process was executed;

[0034] If the number of times the water storage and correction procedure is executed is greater than or equal to the preset number of executions, an alarm message will be output, and the fabric processing equipment will be controlled not to perform the water storage and correction procedure.

[0035] In the above technical solution, the dehydration process also includes a third acceleration stage and a fourth acceleration stage;

[0036] Dehydration control methods also include:

[0037] The control device executes the third acceleration phase at an acceleration a3, and maintains operation for a third preset duration when the third target speed is reached. After the third preset duration is completed, the control device executes the fourth acceleration phase at an acceleration a4, and maintains operation for a fourth preset duration when the fourth target speed is reached.

[0038] The acceleration a4 is less than the acceleration a3.

[0054] Background Introduction

[0055] Currently, most textile processing equipment uses traditional dewatering methods with a single-stage speed increase. When the clothes in the drum are too eccentric, the speed increase is too fast and it is easy to cause the clothes to hit the drum, resulting in a poor user experience. After the clothes hit the safety bar during dewatering, the correction method usually only uses water storage correction. For non-extremely eccentric loads (or non-displacement loads), occasional hits to the bar will trigger water storage correction, while extremely eccentric loads are prone to multiple water storage corrections, thus wasting water resources.

[0056] By testing the rotational speed of the impact rod when the load inside the drum is in a low or medium eccentric state using a traditional dehydration method, it was found that the rotational speed of the impact rod is mostly distributed between 70 rpm and 90 rpm when the load inside the drum is in a low or medium eccentric state. It is speculated that when the dehydration speed is between 70 rpm and 90 rpm, the drum body is at the resonance point, and the probability of impacting the impact rod is higher. Therefore, it is believed that the rotational speed of the impact rod can be used to distinguish the eccentricity inside the drum at this time (*the approximate relationship between the eccentricity level and the weight).

[0057] Off-center gear Eccentric mass / kg low eccentricity ≤1.0 Eccentricity 1.0-1.2 High eccentricity ＞1.2

[0058] By testing the number of impacts with the rod under various eccentric states as the speed V increases from 0 to V1 and is maintained, it was found that the number of impacts differs depending on the eccentricity at V1 speed: when the eccentricity is >1.0kg, there are more / continuous impacts; when the eccentricity is ≤1.0kg, the number of impacts is ≤4. This verifies that (the first distinguishing condition) the magnitude of the load eccentricity inside the drum can be preliminarily determined by detecting whether the number of impacts with the rod at the dehydration speed V1 is >4, distinguishing the load eccentricity level as low-medium and medium-high. It can be basically determined that dehydration can be successfully completed when the eccentricity is ≤1.0kg (low eccentricity). That is to say, it can be considered that the load inside the drum can be initially distinguished with 1.0kg as the boundary. It can be determined that there is no risk of collision or displacement with the rod when the load is low (less than or equal to 1.0kg). However, the situation between 1.0kg and 1.2kg is more complex and requires further assessment to determine whether there is any risk.

[0059] However, at V1 speed, it's difficult to distinguish more precisely whether the eccentric mass can successfully dehydrate (except for low eccentricity). To more accurately differentiate between medium and high eccentricity, and to determine the load mass that can successfully and safely dehydrate after a few / 0 minor impacts to the chamber without significant displacement (i.e., under medium and high eccentricity, there may be a few or even no minor impacts to the chamber, in which case the chamber may vibrate slightly and produce very small displacement; the eccentric mass under these conditions is considered a risk-free load mass that can successfully and safely dehydrate), thus improving the dehydration success rate. By testing the number of impacts at different eccentric states as the speed V increases from 0 to V2 and is maintained, it was found that the number of impacts differs for different eccentricities at V2 speed: when the eccentricity > 1.2 kg, there will be continuous impacts; when 0 kg ≤ eccentricity ≤ 1.2 kg, the number of impacts is ≤ 2 in most cases. It was verified that (the second distinguishing condition) can be used to further determine the magnitude of the load eccentricity in the drum by detecting whether the number of impacts of the rod at the dehydration speed V2 is greater than 2. The load eccentricity level in the drum can be distinguished as low, medium, or high. It can be basically determined that dehydration cannot be successful when the eccentricity is greater than 1.2 kg (high eccentricity).

[0060] Based on the test results of speeds V1 and V2, and combined with the two distinguishing conditions, two speed maintenance tests were set up to test the dehydration stability and operation of each eccentric speed setting. The tests revealed that the medium and high eccentric speeds operate more smoothly when the speed is increased to approximately 140-300 rpm. Therefore, setting the stable speed to V3 indicates that the medium and high eccentric speeds can operate stably at V3 speed. Further increasing the speed thereafter helps reduce the risk of displacement due to excessively rapid speed increases.

[0061] Based on the above test results, such as Figure 1 and Figure 2 As shown, the first aspect of this application provides a dewatering control method for a fabric processing device. The fabric processing device has a dewatering program for dewatering a load. In the dewatering program, the device resonates when the dewatering speed is in the resonant speed range. In this application embodiment, the dewatering program includes a first acceleration stage and a second acceleration stage executed sequentially. The first target speed value of the first acceleration stage is lower than the minimum value of the resonant speed range, and the second target speed value of the second acceleration stage is higher than the maximum value of the resonant speed range.

[0062] Dehydration control methods include:

[0063] During the dehydration process, the number of times the safety bar of the fabric processing equipment is hit during the first and second acceleration stages is obtained, and the water storage and correction program is determined based on the number of times the safety bar is hit.

[0064] If the number of impacts on the safety bar exceeds the maximum permissible number of impacts corresponding to the current acceleration phase, the water storage correction procedure will be executed.

[0065] Conversely, proceed to the next acceleration phase.

[0066] In this embodiment, a segmented acceleration method is adopted during the dehydration process. The number of impacts to the safety bar is checked during the first and second acceleration stages to determine if the current eccentric setting is prone to displacement and whether water storage correction is necessary. If the number of impacts does not exceed the limit, the next acceleration stage proceeds to stabilize the dehydration state of the prototype, enabling it to stably pass the resonance speed and reducing the probability of displacement at higher speeds. Furthermore, during the corresponding acceleration stage, the water storage correction procedure is only executed when the number of impacts to the safety bar exceeds a preset value. This means that in many cases, unnecessary water storage correction can be avoided, thereby conserving water resources.

[0067] This method divides the dehydration process into two stages. In the first stage, the target rotational speed is lower than the minimum value of the resonance speed range, while in the second stage, the target rotational speed is higher than the maximum value of the resonance speed range. This ensures that the fabric processing equipment will not be in the resonance speed range during these two acceleration stages, thus avoiding equipment damage caused by resonance. By monitoring the number of impacts to the safety bar during the first and second acceleration stages and comparing it to the maximum permissible number of impacts, the system can intelligently determine whether a water-retaining correction procedure is needed. This method reduces unnecessary correction operations, improves dehydration efficiency, and conserves water resources.

[0068] In this embodiment of the application, by cleverly controlling the acceleration phase of the dehydration process, the resonant speed range is avoided, thereby improving dehydration efficiency, protecting the equipment, optimizing the user experience, and improving overall safety and economy.

[0069] Furthermore, in some possible implementations, the load eccentricity states include low eccentricity, medium eccentricity, and high eccentricity, wherein...

[0070] The number of times a load in a low eccentricity state impacts the safety bar during the first acceleration phase is less than the first preset impact value; the number of times a load in a medium eccentricity state or a high eccentricity state impacts the safety bar during the first acceleration phase is greater than or equal to the first preset impact value.

[0071] The number of times a load in a low-eccentricity or medium-eccentricity state impacts the mounting rod during the second acceleration phase is less than the second preset impact value, while the number of times a load in a high-eccentricity state impacts the safety bar during the second acceleration phase is greater than or equal to the second preset impact value.

[0072] In this embodiment, by setting specific impact thresholds (a first preset impact value and a second preset impact value), the eccentricity of the load can be detected more accurately, thereby enabling corresponding dehydration control measures. Based on the number of impacts at different acceleration stages for loads with different eccentricities, the dehydration strategy can be intelligently adjusted to adapt to loads with varying degrees of eccentricity, improving dehydration efficiency. By distinguishing eccentricities and taking corresponding corrective measures, equipment impacts and wear caused by eccentric loads can be reduced, extending the equipment's service life.

[0073] In this embodiment, specific impact frequency thresholds are set to distinguish loads in different eccentric states, and the dehydration strategy is intelligently adjusted based on these states. This method helps improve dehydration efficiency, reduce equipment wear, save resources, and enhance user experience.

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

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

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

[0077] Preferably, based on the above test results, in some possible implementations, the first preset impact value is set to 4, and the second preset impact value is set to 2;

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

[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 resonant speed range is between 70 rpm and 90 rpm.

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

[0082] Furthermore, in some possible implementations, the maximum permissible number of impacts during the first acceleration phase is greater than the maximum permissible number of impacts during the second acceleration phase, and the first target rotational speed during the first acceleration phase is less than the second target rotational speed during the second acceleration phase; or

[0083] The maximum number of permissible impacts during the first acceleration phase is 4, and the maximum number of permissible impacts during the second acceleration phase is 2. The first target speed during the first acceleration phase is 55 rpm-70 rpm, and the second target speed during the second acceleration phase is 90 rpm-120 rpm.

[0084] The resonant speed range is 70 rpm to 90 rpm.

[0085] Furthermore, in some possible implementations, the dehydration control method further includes:

[0086] In the first acceleration phase, the speed is increased by acceleration a1 and maintained for a first preset duration when the speed reaches the first target speed;

[0087] In the second acceleration phase, the speed is increased by acceleration a1 and maintained for a second preset duration when the speed reaches the second target speed;

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

[0089] In this embodiment, by setting different preset durations for the two acceleration stages, the dehydration process can be controlled more precisely. In particular, the dehydration effect on the load can be optimized at different acceleration stages. A longer first preset duration allows more time to stabilize the load and dehydrate under low eccentricity conditions, while a shorter second preset duration is suitable for medium and high eccentricity conditions, reducing the holding time at higher speeds that may cause resonance. Simultaneously, since the first target speed is lower than the minimum value of the resonance speed range, maintaining a longer duration in the first acceleration stage can reduce the risk of resonance. The second target speed in the second acceleration stage is higher than the maximum value of the resonance speed range, so the holding time is shorter to quickly pass through the speed range that may cause resonance. Furthermore, allowing more time for dehydration in the first acceleration stage allows for more effective water removal at lower speeds, especially when the load eccentricity is small. By reducing the holding time in the second acceleration stage, the risk of equipment wear and failure at higher speeds can be reduced. Especially when the load eccentricity is large, balancing the dehydration effect and energy consumption between the two stages can reduce energy consumption without affecting the dehydration effect.

[0090] Furthermore, in some possible implementations, the dehydration control method further includes:

[0091] After performing the water storage and correction procedure, the dehydration procedure is performed again.

[0092] Furthermore, in some possible implementations, the dehydration control method further includes:

[0093] During the dehydration process, the total number of times the safety bar was impacted was obtained;

[0094] If the total number of impacts on the safety bar is greater than or equal to the preset number of impacts, an alarm message will be output, and the fabric processing equipment will be controlled not to perform the water storage and correction procedure.

[0095] and / or

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

[0097] If the number of times the water storage and correction procedure is executed is greater than or equal to the preset number of executions, an alarm message will be output, and the fabric processing equipment will be controlled not to perform the water storage and correction procedure.

[0098] It's important to note that the number of impacts to the safety bar is directly related to the eccentricity of the spin-drying drum and the stability of the spin-drying process. Excessive impacts may indicate severe load eccentricity or other problems, requiring timely intervention to prevent equipment damage. Monitoring the number of impacts to the safety bar allows for preventative maintenance or adjustments before problems escalate, reducing the risk of sudden malfunctions. Alarm messages can promptly notify users of potential issues during the spin-drying process, enabling them to take appropriate measures, such as rebalancing the load or checking the equipment status. Furthermore, monitoring the number of impacts provides manufacturers with data for improving product design and optimizing spin-drying control algorithms.

[0099] In this embodiment, by adding a monitoring and alarm mechanism for the number of impacts to the safety bar, the aim is to reduce the risk of equipment damage, improve the safety and reliability of the dehydration process, and enhance the user experience and the intelligence level of the equipment. This approach helps reduce maintenance costs and provides data support for continuous product improvement.

[0100] It's also important to note that the number of times the water-filling correction program is executed reflects the severity of load misalignment during the spin-drying process. Frequent execution of the correction program may indicate a need to adjust the spin-drying control method or a problem with the equipment. Furthermore, frequent water-filling correction not only consumes additional water resources but can also increase energy consumption and wear on the equipment. Setting a preset execution count can prevent unnecessary resource waste. Excessive execution of the correction program may be due to severe load misalignment or equipment malfunction. Outputting alarm messages can remind users or maintenance personnel to inspect the equipment to prevent damage. Alarm messages can guide users to reallocate the washing load or take other measures to reduce misalignment and the number of correction program executions.

[0101] In this embodiment, by adding a monitoring and alarm mechanism for the number of times the water storage correction procedure is executed, the aim is to improve dehydration efficiency, save resources, protect equipment, and enhance user experience and the intelligence level of the equipment. This method helps reduce maintenance costs and provides data support for continuous product improvement.

[0102] Furthermore, in some possible implementations, the dehydration process also includes a third acceleration stage and a fourth acceleration stage;

[0103] Dehydration control methods also include:

[0104] The control device executes the third acceleration phase at an acceleration a3, and maintains operation for a third preset duration when the third target speed is reached. After the third preset duration is completed, the control device executes the fourth acceleration phase at an acceleration a4, and maintains operation for a fourth preset duration when the fourth target speed is reached.

[0105] The acceleration a4 is less than the acceleration a3.

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

[0107] In this embodiment, by reducing the acceleration in the fourth acceleration stage, the acceleration speed can be controlled to prevent the motor from overheating.

[0108] It should be noted that the reason for setting a third acceleration stage and setting the acceleration of the third acceleration stage to be greater than that of the fourth acceleration stage in this embodiment is to quickly overcome the secondary resonance speed that may cause the drum to bounce during the third acceleration stage (the aforementioned 70rpm-90rpm is the first resonance speed that may cause the drum to bounce). The reason for setting a fourth acceleration stage is that the target speed of the third stage is relatively low, and maintaining this speed will not achieve the required moisture content of the clothes after dehydration. Therefore, it is necessary to accelerate to the higher speed of the fourth acceleration stage so that the drum can dehydrate at a higher speed. However, if a large acceleration is maintained for a long time, the motor will heat up faster, resulting in high power consumption and losses, which may easily cause the motor to overheat. Therefore, the acceleration of the fourth acceleration stage needs to be set to be smaller.

[0109] Preferably, in some possible implementations, the third acceleration stage has a third target speed and the fourth acceleration stage has a fourth target speed.

[0110] The third target speed ranges from 140 rpm to 300 rpm, and the fourth target speed ranges from 550 rpm to 900 rpm, with the fourth target speed being greater than the maximum value of the second resonance speed.

[0111] The acceleration a1 ranges from 0.5 rpm to 0.8 rpm, and the acceleration a2 ranges from 0.15 rpm to 0.4 rpm.

[0112] It is worth noting that, as the above tests show, loads with medium and high eccentricity operate more smoothly when the speed is increased to around 140-300 rpm. Therefore, setting the stable speed for the third acceleration stage between 140-300 rpm can be considered as ensuring that loads with medium and high eccentricity can operate stably within this range. Further acceleration after this point helps reduce the risk of displacement caused by excessively rapid speed increases.

[0113] Specifically, to better understand the control logic of the dehydration control method provided in this embodiment, the following will be combined with... Figure 2 Please provide a detailed explanation:

[0114] like Figure 2 As shown: After the fabric processing equipment finishes draining and begins the dewatering process, the acceleration process is divided into 4 acceleration stages, and 2 detections are added:

[0115] First stage: Distinguish between low eccentricity and low-to-medium eccentricity loads, whose operating status is relatively stable, and determine whether they meet the conditions for entering the second stage, so as to 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 operating state is unstable. It is determined that the eccentricity exceeds the range that can be corrected by speed, and water storage correction is initiated.

[0117] Acceleration a1, rotational speed V:0→V1, V1 maintained for 10s, during which the number of collisions with the rod is greater than 4?

[0118] Determine if its condition is suitable for entering the second stage of acceleration:

[0119] If the number of collisions with the pole exceeds 4, the system will enter the water storage and correction phase.

[0120] If the number of times the pole is hit is ≤4, then proceed to the second stage of acceleration;

[0121] The second stage: Identify the relatively stable eccentricity value in the medium eccentricity gear (here, medium eccentricity is 1.0-1.2kg), determine whether it meets the conditions for entering the third stage, and keep it in a stable state to enter the third stage of acceleration.

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

[0123] Acceleration a1, rotational speed V: V1→V2, V2 maintained for 5s, during which the number of times the rod is hit is greater than 2?

[0124] Determine if its condition is suitable for entering the third stage of acceleration:

[0125] If the number of times the pole is hit is greater than 2, then water storage and correction will be initiated.

[0126] If the number of times the pole is hit is less than or equal to 2, then the third stage of acceleration will begin.

[0127] The third stage is set up to stabilize the eccentricity state again after two tests to prevent sudden changes in eccentricity due to excessive acceleration.

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

[0129] Fourth stage: acceleration a2, rotational speed V: V3→V4, until V4→0.

[0130] Full process:

[0131] 1. To address sudden eccentricity of the prototype outside the testing phase, a full-process collision count detection system is implemented (including collision counts detected in the early stages);

[0132] Is the total number of times the test bar hits during the entire dehydration process ≥8?

[0133] Determine whether a fault message should be displayed based on its status:

[0134] If the number of water storage correction attempts is ≤2, then the water storage correction process will proceed normally.

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

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

[0137] The number of water storage and correction cycles during the entire dehydration process is greater than 2.

[0138] Determine whether a fault message should be displayed based on its status:

[0139] If the number of water storage correction attempts is ≤2, no fault alarm will be triggered;

[0140] If the number of water storage correction attempts is greater than 2, it indicates a dehydration imbalance fault.

[0141] It is worth noting that the water storage and correction program refers to the process where the equipment washes for a few minutes after water is introduced, adjusts the position of the clothes in the water, and then drains the water to attempt spin-drying.
