Description

[Technical Field]

[0001] This invention relates to the field of home appliance technology, and more particularly to a control method for a clothing handling device. [Background Technology]

[0002] As people have higher requirements for laundry hygiene, many families require that underwear and outerwear be washed separately, or that adult and children's clothes be washed separately. There are also needs to separate clothes of different colors or materials. In situations with limited space, twin-drum washing machines are becoming increasingly popular. To save space, the two drums of a twin-drum washing machine are generally arranged one above the other.

[0003] When both drums are working simultaneously and both are in the spin-drying stage, the high-speed rotation of the two drums will cause strong vibrations, which will damage the washing machine and affect its service life.

[0004] Therefore, a control method for twin-drum washing machines is developed to control the simultaneous spin-drying of both drums. Before the drums spin-dry, an eccentricity detection is performed, and the maximum permissible spin speed is determined based on the eccentricity range. The subsequent drum then determines its spin speed based on the speed of the first drum. This solution reduces resonance during simultaneous spin-drying by controlling the speed of the second drum. If the first drum's speed is too high, the second drum may not reach the predetermined spin speed, resulting in clothes not being fully dried. [Summary of the Invention]

[0005] The purpose of this invention is to provide a control method for a garment processing device, which can at least partially solve the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A method for controlling a garment processing device, wherein the garment processing device includes at least:

[0008] The independently operating first processing cylinder can perform at least one processing stage that requires eccentricity detection;

[0009] The independently operating second processing cylinder can perform at least one processing stage that requires eccentricity detection;

[0010] The control method includes:

[0011] When the first processing cylinder needs to perform a processing stage, it is determined whether the second processing cylinder is in a processing stage.

[0012] If so, control the second processing cylinder to reduce to the eccentric detection speed or pause and allow the first processing cylinder to perform the processing stage;

[0013] The first processing cylinder and the second processing cylinder each perform eccentricity detection in the processing stage, obtain the first eccentricity value of the first processing cylinder and the second eccentricity value of the second processing cylinder, and combine the first eccentricity value and the second eccentricity value to determine whether the multi-cylinder eccentricity threshold is met. If so, the first processing cylinder and the second processing cylinder are allowed to perform their respective processing stages simultaneously.

[0014] In the control method of the above-mentioned garment processing device, when it is determined that the second processing drum is in the processing stage, the second processing drum selects to slow down or stop based on its own second eccentricity value:

[0015] If the second eccentricity value meets the second single-cylinder eccentricity threshold, then the second processing cylinder is controlled to decrease to the eccentricity detection speed;

[0016] If the second eccentricity value does not meet the second single-tube eccentricity threshold, then the second processing tube is controlled to pause.

[0017] In the control method of the above-mentioned garment processing device, when the second eccentricity value does not meet the second single-tube eccentricity threshold, the second processing tube is first reduced to below the critical speed at which the garment is in close contact with the tube wall, and then the speed is increased to the eccentricity detection speed. The eccentricity detection is performed again to obtain the second eccentricity value. If the second eccentricity value still does not meet the second single-tube eccentricity threshold, the second processing tube is controlled to pause. If the second eccentricity value meets the second single-tube eccentricity threshold, the second processing tube is kept at the eccentricity detection speed.

[0018] In the control method of the above-mentioned clothing processing device, the eccentric detection speed is not lower than the critical speed at which the clothing adheres tightly to the wall of the second processing cylinder.

[0019] In the control method of the above-mentioned clothing processing device, when the first processing tube needs to perform a processing stage, the second processing tube is controlled to pause.

[0020] The first processing cylinder performs eccentricity detection during the processing stage and obtains a first eccentricity value that meets the first single-cylinder eccentricity threshold.

[0021] The second processing cylinder continues to perform the processing stage and performs the eccentricity detection of the processing stage to obtain the second eccentricity value;

[0022] The first eccentricity value and the second eccentricity value are combined to determine whether the multi-tube eccentricity threshold is met.

[0023] In the control method of the above-mentioned clothing processing device, when the first processing drum needs to perform the processing stage, the second processing drum is controlled to drop to the eccentricity detection speed and perform eccentricity detection to obtain its own second eccentricity value.

[0024] The first processing cylinder performs eccentricity detection during the processing stage and obtains a first eccentricity value that meets the first single-cylinder eccentricity threshold.

[0025] The first eccentricity value and the second eccentricity value are combined to determine whether the multi-tube eccentricity threshold is met.

[0026] In the above-mentioned control method of the garment processing device, the determination of whether the second processing drum is in the processing stage is based on the detection of the eccentricity value by the garment processing device: the eccentricity value of the second processing drum during operation is detected in real time, and when a valid eccentricity value is detected, the second processing drum is determined to be in the processing stage.

[0027] Alternatively, the determination of whether the second processing cylinder is in the processing stage is based on the judgment of the processing stage time progress: when the actual running time of the second processing cylinder reaches the processing stage time progress, it is determined that the second processing cylinder is in the processing stage.

[0028] In the control method of the above-mentioned clothing processing device, when it is determined that the second processing tube is not in the processing stage, the first processing tube is allowed to perform the processing stage under the condition that the first eccentricity value meets the first single tube eccentricity threshold.

[0029] In the control method of the above-mentioned garment handling device, determining whether the multi-tube eccentricity threshold is met by combining the first eccentricity value and the second eccentricity value includes:

[0030] The first eccentricity value is set to a, the second eccentricity value is set to b, and the multi-cylinder eccentricity threshold is set to c;

[0031] It satisfies a+b≤c; or it satisfies a*b≤c.

[0032] In the control method of the above-mentioned garment processing device, the processing stage includes a dehydration stage and / or a fabric quantity detection stage.

[0033] The beneficial effects of this invention are:

[0034] By slowing down the second processing drum in the processing stage and re-detecting the eccentricity value, which is then combined with the first eccentricity value to determine whether the multi-drum eccentricity threshold is met, the problem of poor or low efficiency in multi-drum dehydration is solved. When the first processing drum needs to perform the processing stage, if the second processing drum is already in the processing stage, the second processing drum is controlled to reduce its eccentricity detection speed or pause. Since the second processing drum has already been in the processing stage, the moisture content of the clothes in the second processing drum has decreased, and the value of the second eccentricity value will also decrease. At this time, allowing the first processing drum to perform the processing stage allows for a larger range of the first eccentricity value, enabling the first processing drum to enter the processing stage more quickly. The first and second eccentricity values ​​are combined to determine whether the multi-drum eccentricity threshold is met. If it is, the two processing drums each perform their respective processing stages. The speeds of the two processing drums in the processing stage will not interfere with each other. They can operate at their respective set maximum speeds or reach their maximum speeds simultaneously, allowing both processing drums to achieve the predetermined dehydration rate. The total dehydration time is also shortened, and the vibration generated when the two processing drums perform the processing stage simultaneously is also reduced.

[0035] In a further embodiment, when the second processing cylinder is determined to be in the processing stage, the second processing cylinder chooses to reduce its speed or pause based on its own second eccentricity value: if the second eccentricity value meets the second single-cylinder eccentricity threshold, the second processing cylinder is controlled to reduce to the eccentricity detection speed; if the second eccentricity value does not meet the second single-cylinder eccentricity threshold, the second processing cylinder is controlled to pause. The second single-cylinder eccentricity threshold is used to determine whether the second processing cylinder should pause operation. When the second eccentricity value meets the second single-cylinder eccentricity threshold, sufficient adjustment space for the first processing cylinder's first eccentricity value can be provided, so that the combined first and second eccentricity values ​​can satisfy the multi-cylinder eccentricity threshold; if the second eccentricity value does not meet the second single-cylinder eccentricity threshold, the range for adjusting the first eccentricity value for the first processing cylinder is too small, and the second processing cylinder pauses operation, allowing the first processing cylinder to proceed with the processing stage.

[0036] In a further scheme, when the second eccentricity value does not meet the second single-tube eccentricity threshold, the second processing tube is first reduced to below the critical speed at which the clothing adheres tightly to the tube wall, and then accelerated to the eccentricity detection speed. Eccentricity detection is then performed again to obtain the second eccentricity value. If the second eccentricity value still does not meet the second single-tube eccentricity threshold, the second processing tube is paused. If the second eccentricity value meets the second single-tube eccentricity threshold, the second processing tube is maintained at the eccentricity detection speed. Since the second processing tube has already been in the processing stage, reducing its speed to below the critical speed allows the clothing to roll within the tube, redistributing its position. Then, the speed is increased back to the eccentricity detection speed, causing the clothing to rotate with the tube. Eccentricity detection is then performed again to obtain the second eccentricity value, thus obtaining a new second eccentricity value. Generally, the second eccentricity value obtained after the above steps will decrease.

[0037] In a further embodiment, the eccentricity detection speed is not lower than the critical speed at which the clothing adheres tightly to the wall of the second processing drum. Once the eccentricity detection speed meets this condition, the clothing will remain tightly adhered to the wall of the second processing drum during eccentricity detection; that is, the clothing will rotate together with the wall of the second processing drum. At this point, the second eccentricity value of the second processing drum will be relatively stable, thus obtaining a more accurate second eccentricity value.

[0038] In a further embodiment, when the first processing cylinder needs to perform a processing stage, the second processing cylinder is paused; the first processing cylinder performs eccentricity detection during the processing stage and obtains a first eccentricity value that meets the first single-cylinder eccentricity threshold; the second processing cylinder continues to perform the processing stage and performs eccentricity detection during the processing stage, obtaining a second eccentricity value; the first eccentricity value and the second eccentricity value are combined to determine whether the multi-cylinder eccentricity threshold is met. Another method for re-obtaining the eccentricity values ​​of the two processing cylinders involves pausing the second processing cylinder and then resuming the processing stage, reducing the judgment process and obtaining a more accurate second eccentricity value.

[0039] In a further embodiment, when the first processing cylinder needs to perform a processing stage, the second processing cylinder is controlled to reduce its eccentricity detection speed and perform eccentricity detection to obtain its own second eccentricity value; the first processing cylinder performs eccentricity detection during the processing stage and obtains a first eccentricity value that meets the first single-cylinder eccentricity threshold; the first eccentricity value and the second eccentricity value are combined to determine whether the multi-cylinder eccentricity threshold is met. Another method for re-obtaining the eccentricity values ​​of the two processing cylinders minimizes the impact on the rotational speed of the second processing cylinder when re-obtaining the second eccentricity value, allowing the second processing cylinder to shorten the processing stage time.

[0040] In a further scheme, determining whether the second processing drum is in the processing stage is based on the detection of eccentricity value by the garment processing device: the eccentricity value of the second processing drum is detected in real time, and when a valid eccentricity value is detected, the second processing drum is determined to be in the processing stage; or, determining whether the second processing drum is in the processing stage is based on the judgment of the processing stage time progress: when the actual running time of the second processing drum reaches the processing stage time progress, the second processing drum is determined to be in the processing stage. These two different methods for determining whether the second processing drum is in the processing stage are: one is based on eccentricity value judgment, since the processing drum only generates a large eccentricity value during the fabric weight judgment and dehydration stages, therefore, the magnitude of the eccentricity value can clearly indicate whether the processing drum is currently in the processing stage. This method, by directly detecting the second eccentricity value, avoids interference from other data or unexpected situations, making the judgment of whether the second processing drum is in the processing stage relatively accurate; the other is based on time judgment, since the processing flow and processing time in the garment processing device correspond one-to-one, the time of the processing stage can accurately determine whether the current second processing drum is in the processing stage, and the judgment logic is relatively simple.

[0041] In a further embodiment, when it is determined that the second processing cylinder is not in the processing stage, the first processing cylinder is allowed to perform the processing stage under the condition that the first eccentricity value meets the first single-cylinder eccentricity threshold. When the second processing cylinder is not in the processing stage, the resonance problem of two processing cylinders being in the processing stage simultaneously will not occur, and there is no need to consider the limitation of the multi-cylinder eccentricity threshold. The first processing cylinder performs the processing stage under the condition that the first eccentricity value meets the first single-cylinder eccentricity threshold.

[0042] In a further scheme, determining whether the multi-tube eccentricity threshold is met by combining the first eccentricity value and the second eccentricity value includes: setting the first eccentricity value as 'a', the second eccentricity value as 'b', and the multi-tube eccentricity threshold as 'c'; satisfying a + b ≤ c; or satisfying a * b ≤ c. These two different methods for determining whether the first and second eccentricity values ​​meet the multi-tube eccentricity threshold have simple logic and can quickly yield the results.

[0043] In a further embodiment, the processing stage includes a dehydration stage and / or a fabric quantity detection stage. Both the dehydration stage and the fabric quantity detection stage require the processing cylinders to rotate at high speeds. Therefore, eccentricity detection needs to be performed in at least one of these stages to ensure that when two processing cylinders need to enter the processing stage simultaneously, their respective eccentricity values ​​can be obtained for a comprehensive judgment on whether the multi-cylinder eccentricity threshold is met.

[0044] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0051] A method for controlling a garment processing device, wherein the garment processing device includes at least:

[0052] The independently operating first processing cylinder can perform at least one processing stage that requires eccentricity detection;

[0053] The independently operating second processing cylinder can perform at least one processing stage that requires eccentricity detection;

[0054] The control method includes:

[0055] When the first processing cylinder needs to perform a processing stage, it is determined whether the second processing cylinder is in a processing stage.

[0056] If so, control the second processing cylinder to reduce to the eccentric detection speed or pause and allow the first processing cylinder to perform the processing stage;

[0057] The first processing cylinder and the second processing cylinder each perform eccentricity detection in the processing stage, obtain the first eccentricity value of the first processing cylinder and the second eccentricity value of the second processing cylinder, and combine the first eccentricity value and the second eccentricity value to determine whether the multi-cylinder eccentricity threshold is met. If so, the first processing cylinder and the second processing cylinder are allowed to perform their respective processing stages simultaneously.

[0058] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0059] Example 1

[0060] The garment processing device includes at least: a first processing drum that operates independently and can perform at least one processing stage requiring eccentricity detection; and a second processing drum that operates independently and can perform at least one processing stage requiring eccentricity detection.

[0061] The eccentricity detection stage differs from other stages of the washing drum (such as washing / rinsing). It requires the drum to rotate at high speed or accelerate to perform dehydration or fabric weight detection. Eccentricity detection is introduced to obtain an eccentricity value that reflects the distribution of clothes in the drum. When the eccentricity value is large, it indicates that the clothes are unevenly distributed in the washing drum. For single-drum washing devices, the distribution of clothes can be readjusted to make the eccentricity value meet the set threshold. For multi-drum washing devices, when multiple drums need to perform the above-mentioned processing stage at the same time, the vibration of multiple drums will superimpose and cause resonance problems. Unless multiple drums are prevented from performing the processing stage at the same time as in existing technologies, which would prolong the user's waiting time, or the maximum speed of a single drum is controlled, the speed-limited drum will not be able to achieve the expected processing effect.

[0062] In this embodiment, it is not necessary to limit the rotational speed of the first and second processing drums. As mentioned above, the eccentricity value only reflects the distribution of clothing within the drum. Vibration occurs during high-speed / accelerated operation in the processing stage. As long as the eccentricity value meets the requirements, the vibration of the processing drum during high-speed / accelerated operation in the processing stage is controlled. Existing technology cannot solve the resonance problem by adjusting the rotational speed of the processing drum. However, in this embodiment, by adjusting the eccentricity value of the processing drum, under the condition that the first and second eccentricity values ​​meet the multi-drum eccentricity threshold, the first and second processing drums are allowed to simultaneously perform the above-mentioned processing stage. This allows the resonance to be controlled within an acceptable range, while enabling both the first and second processing drums to reach their respective maximum rotational speeds, ensuring the clothing processing effect. This multi-drum eccentricity threshold can be set by comprehensively considering motor load, vibration noise, and other requirements, and the resonance is controlled within an acceptable range.

[0063] For ease of explanation, the processing stage requiring eccentricity detection described in this embodiment is the dehydration stage.

[0064] like Figure 1As shown, the control method of the garment processing device includes: when the first processing drum needs to perform a dehydration stage, determining whether the second processing drum is already in the dehydration stage. If the second processing drum is already in the dehydration stage, controlling the second processing drum to reduce its eccentricity detection speed or pause it, and allowing the first processing drum to perform the dehydration stage, then the first and second processing drums each perform eccentricity detection for the dehydration stage, obtaining a first eccentricity value for the first processing drum and a second eccentricity value for the second eccentricity drum, and combining the first and second eccentricity values ​​to determine whether the multi-drum eccentricity threshold is met. If yes, then allowing the first and second processing drums to simultaneously perform their respective dehydration stages. If not, adjusting the speed of the first or second processing drum, reducing it below the garment-adhering speed, readjusting the garment distribution within the processing drum, and then increasing it above the adhering speed, re-obtaining the eccentricity value, until the multi-drum eccentricity threshold is met. Since the second processing drum is already in the dehydration stage before the first processing drum begins its dehydration phase, the moisture content of the clothes in the second processing drum has already decreased. At this point, if the second processing drum slows down to its eccentric detection speed or pauses to allow the first processing drum to begin its dehydration phase, the eccentricity value of the second processing drum will be smaller than when it first entered the dehydration stage. When comprehensively judging whether the multi-drum eccentricity threshold is met, the first eccentric drum will be allowed a larger range of eccentricity values, allowing both processing drums to execute their respective processing stages more quickly. Alternatively, the resonance generated when the first and second eccentric drums enter the dehydration stage simultaneously will be smaller, resulting in quieter operation of the garment processing device. If the comprehensive judgment does not meet the multi-drum eccentricity threshold, allowing the first eccentric drum to enter the dehydration stage first, the lower moisture content of the clothes in the second processing drum makes it easier to continue adjusting the eccentricity value until the multi-drum eccentricity threshold is met before entering the dehydration stage.

[0065] like Figure 2 As shown in this embodiment, the basis for controlling whether the second processing drum decreases to the eccentricity detection speed or pauses is to determine whether the second eccentricity value meets the second single-drum eccentricity threshold. If the second eccentricity value meets the second single-drum eccentricity threshold, it means that the second eccentricity value is small. In this case, the second processing drum only needs to decrease to the eccentricity detection speed and does not need to decrease the speed further, so that the second processing drum can quickly increase the speed to continue the processing stage. If the second eccentricity value does not meet the second single-drum eccentricity threshold, it means that the current second eccentricity value is high. The second processing drum needs to pause operation and then resume to the eccentricity detection speed to better readjust the distribution of clothes in the processing drum. The second eccentricity value is then compared with the second single-drum eccentricity threshold until the multi-drum eccentricity threshold is met before entering the processing stage.

[0066] Furthermore, to improve processing efficiency, when the second eccentricity value does not meet the second single-tube eccentricity threshold, the second processing drum is not immediately paused. Instead, the second processing drum is slowed down to below the critical speed at which the clothes adhere to the drum wall, preventing the clothes from rotating synchronously with the drum. This adjusts the distribution of the clothes within the drum. The speed of the second processing drum is then increased to the eccentricity detection speed, and the second eccentricity value is re-acquired. If the second single-tube eccentricity threshold is still not met, the second processing drum is paused again, and the above steps are repeated. If the second eccentricity value meets the threshold, the drum maintains the eccentricity detection speed. Through these steps, the second eccentricity value is re-detected, and the new value is used to determine whether the threshold is met, resulting in a more accurate acquisition of the second eccentricity value, reducing the need for the second eccentric drum to pause, and improving the efficiency of the dehydration stage.

[0067] In the above embodiment, the eccentricity detection speed is not lower than the critical speed at which the clothes adhere tightly to the wall of the second processing drum. This critical speed is the minimum speed at which a stable second eccentricity value is obtained. If the speed is lower than this, the clothes will detach from the drum wall and redistribute. By continuously adjusting the speed of the second processing drum to the eccentricity detection speed, a new second eccentricity value is obtained. The fact that the eccentricity detection speed is not lower than the critical speed also ensures that when the second eccentricity value is obtained, the clothes in the second processing drum rotate together with the second processing drum, resulting in a relatively stable second eccentricity value.

[0068] In the above embodiments, the methods for determining whether the second processing cylinder is in the dehydration stage include, but are not limited to, the following:

[0069] 1. When the actual running time of the second processing tank reaches the dehydration stage, it is determined that the second processing tank is in the dehydration stage. Because the processing tank's operating program has a time limit, the current operating status of the second processing tank can be accurately determined by time. In other words, time can clearly indicate whether the second processing tank is already in the dehydration stage when the first processing tank is about to enter it. This method avoids continuously monitoring the second processing tank's operating data; determining the status by time is logically simple in terms of program judgment.

[0070] II. Real-time detection of the eccentricity value during the operation of the second processing drum. When a valid eccentricity value is detected, the second processing drum is determined to be in the dehydration stage. This method is not time-constrained but rather judges based on the actual operating conditions of the second processing drum. During the dehydration stage, when eccentricity detection is required, the eccentricity value of the second processing drum will be relatively large; while during the washing stage, the drum rotates slowly, and the eccentricity value will be very small. By collecting a certain amount of data, a threshold for the eccentricity value when the second processing drum is in the processing stage and not in the processing stage can be distinguished. By comparing the real-time eccentricity value of the second processing drum with the threshold, it is possible to accurately determine whether the second processing drum is in the dehydration stage. This method directly judges based on the eccentricity value of the second processing drum, providing a more realistic and accurate assessment of its operating status.

[0071] like Figure 3 As shown, if the second processing drum is not in the processing stage, its state will not significantly affect the vibration of the entire garment processing device. The vibration impact mainly comes from the first processing drum performing the processing stage. Therefore, when the second processing drum is not in the processing stage, the first processing drum performs the dehydration stage under the condition that the first eccentricity value meets the first single-drum eccentricity threshold, which ensures that the vibration of the garment processing device is within the design range. Specifically, the first processing drum is first accelerated to the eccentricity detection speed to obtain the first eccentricity value. Then, it is compared to see if the first eccentricity value meets the first single-drum eccentricity threshold. If it does, the first processing drum begins the dehydration stage; if not, the first processing drum is reduced to below the critical speed at which the garment adheres tightly to the drum wall, allowing the garment to be rearranged within the drum. The speed is then increased back to the eccentricity detection speed, the first eccentricity value is obtained again, and the first single-drum eccentricity threshold is checked again until it is met.

[0072] In the above embodiments, the processing stage can include not only the dehydration stage but also the fabric weight detection stage, or a combination of both. During these two stages, the rotation speed of the processing drums is relatively high, resulting in significant eccentricity and the most noticeable vibration to the entire garment processing device. Alternatively, the processing stage can also be the foaming stage of washing. The resonance is greatest when both processing drums are simultaneously in the processing stage. Therefore, when one processing drum is in the dehydration or fabric weight detection stage, the other processing drum entering the processing stage later will adjust its eccentricity to ensure that the first and second eccentricities satisfy the multi-drum eccentricity threshold.

[0073] The determination of whether the multi-tube eccentricity threshold is met by combining the first and second eccentricity values ​​includes: assuming the first eccentricity value is set to 'a', the second eccentricity value is set to 'b', and the multi-tube eccentricity threshold is set to 'c'; satisfying a + b ≤ c; for example, if the multi-tube eccentricity threshold is set to 10, and the second eccentricity value is re-obtained as 6, and the first eccentricity value of the first processing tube is 5, then the first eccentricity value 5 + the second eccentricity value 6 > the multi-tube eccentricity threshold of 10. At this time, the second processing tube is adjusted, and the speed of the second processing tube is reduced to below the critical speed. At this time, the clothes in the second processing tube will not rotate synchronously with the second processing tube, and the clothes will be redistributed in the second processing tube. After the speed of the second processing tube exceeds the critical speed, the second eccentricity value is re-detected until the second eccentricity value b ≤ 4. Then the first eccentricity value 5 + the second eccentricity value 4 < the multi-tube eccentricity threshold of 10. After this, the first and second processing tubes will run according to the speed set in the processing stage program. In addition to using a+b≤c, it is also possible to determine whether a*b≤c is satisfied. Of course, the value of the multi-tube eccentricity threshold under this judgment rule is different from the value of the multi-tube eccentricity threshold determined by the sum of the first eccentricity value and the second eccentricity value. The specific value of the multi-tube eccentricity threshold is determined comprehensively based on the judgment method and parameters such as the safe operation status of the garment processing device.

[0074] In the above embodiments, if the first processing cylinder performs the processing stage first, and the second processing cylinder needs to perform the processing stage during this process, the positions of the first and second processing cylinders in the above embodiments are interchanged. That is, the first processing cylinder is controlled to reduce to the eccentricity detection speed or pause and the second processing cylinder is allowed to perform the processing stage. The first and second processing cylinders each perform the eccentricity detection of the processing stage, obtain the first eccentricity value of the first processing cylinder and the second eccentricity value of the second processing cylinder, and combine the first and second eccentricity values ​​to determine whether the multi-cylinder eccentricity threshold is met. If so, the first and second processing cylinders are allowed to perform their respective processing stages simultaneously.

[0075] The control method of the garment processing device of the present invention, when the first processing drum needs to perform a processing stage, first detects whether the second processing drum is in a processing stage. If not, the first processing drum performs the processing stage under the condition that the first eccentricity value meets the first single-drum eccentricity threshold, and the first processing drum will run at the highest speed set for the processing stage. If yes, the second processing drum is controlled to reduce its speed to the eccentricity detection speed or pause. Since the second processing drum has already performed a processing stage for a period of time, some water has been removed from the clothes in the second processing drum. After the second processing drum reduces its speed or stops, the value of the eccentricity detection will be lower than the previous eccentricity value. In this way, the allowable range of the first eccentricity value of the first processing drum will be increased, and the vibration amplitude when the first and second processing drums enter the processing stage simultaneously will also be reduced. As long as the eccentricity values ​​of the two processing drums meet the multi-drum eccentricity threshold, the above method can not only effectively reduce the vibration amplitude when the two processing drums enter the processing stage simultaneously, but also allow the two processing drums to run at their respective highest speeds according to the processing stage program settings without interfering with each other, thereby ensuring the dehydration rate and dehydration efficiency of each processing drum.

[0076] Example 2

[0077] like Figure 4 As shown, the difference from Embodiment 1 is that when the first processing tube needs to perform the processing stage, the second processing tube is controlled to pause operation. The first processing tube performs the eccentricity detection of the processing stage and obtains the first eccentricity value that meets the first single-tube eccentricity threshold. If it does not meet the first single-tube eccentricity threshold, the first processing tube slows down to below the critical speed at which the clothes are in close contact with the wall of the first processing tube, and then speeds up again to the eccentricity detection speed to obtain the first eccentricity value, until it meets the first single-tube eccentricity threshold.

[0078] The second processing cylinder continues to execute the processing stage and performs eccentricity detection during the processing stage to obtain a second eccentricity value. The first and second eccentricity values ​​are then combined to determine whether the multi-cylinder eccentricity threshold is met. If it is met, the first and second processing cylinders each execute their respective processing stages. If not, the second processing cylinder slows down to below the critical speed at which the clothing adheres tightly to the cylinder wall, then speeds up again to the eccentricity detection speed, re-obtains the second eccentricity value, and then determines whether the multi-cylinder eccentricity threshold is met, until the multi-cylinder eccentricity threshold is met.

[0079] After the first eccentricity value meets the first single-tube eccentricity threshold, the second processing tube, having restarted from a pause, enters the processing stage. The clothes inside the second processing tube, after partial dehydration, will be readjusted and distributed to achieve a lower second eccentricity value. This results in less vibration in the clothing processing device when both the first and second eccentric tubes enter the processing stage simultaneously. This method involves fewer detection and execution steps for the second eccentric tube, simplifying the process.

[0080] Other content not described in this embodiment can be found in Embodiment 1.

[0081] Example 3

[0082] like Figure 5 As shown, the difference from Embodiment 1 is that when the first processing tube needs to perform the processing stage, the second processing tube is controlled to decrease to the eccentricity detection speed and perform eccentricity detection to obtain its own second eccentricity value; the first processing tube performs eccentricity detection in the processing stage and obtains the first eccentricity value that meets the first single-tube eccentricity threshold. If it does not meet the first single-tube eccentricity threshold, the first processing tube decreases its speed to below the critical speed at which the clothes are in close contact with the wall of the first processing tube, and then increases its speed again to the eccentricity detection speed to obtain the first eccentricity value, until it meets the first single-tube eccentricity threshold.

[0083] The first and second eccentricity values ​​are combined to determine whether the multi-tube eccentricity threshold is met. If it is met, the first and second processing tubes execute their respective processing stages. If it is not met, the second processing tube slows down to below the critical speed at which the clothing adheres tightly to the tube wall, then speeds up again to the eccentricity detection speed. The second eccentricity value is then re-acquired, and the multi-tube eccentricity threshold is determined again until it is met.

[0084] In this embodiment, the second processing cylinder will not be paused and will always remain running, which will effectively ensure the processing efficiency of the second processing cylinder.
