Description

Technical Field

[0001] This invention belongs to the field of clothing processing devices, specifically, it relates to a control method for a clothing processing device and a clothing processing device. Background Technology

[0002] Front-loading washing machines represent the future trend in household applications, washing clothes cleanly without damaging them. Currently, most front-loading washer-dryers on the market consist of only one washing tub. As people's living standards improve, their hygiene awareness also increases, especially regarding household laundry. More and more people are separating their clothes for washing. For example, washing inner and outer garments separately, baby and adult clothes separately, clothes of different colors separately, or washing small loads of laundry promptly. Using existing washing machines to meet these needs not only wastes a lot of energy and water but also fails to satisfy users' hygiene requirements. Many families will need more than one front-loading washing machine; however, purchasing two or more washing machines to meet these needs not only increases costs but also creates the inconvenience of taking up too much space.

[0003] Due to limited residential space, multiple front-loading washing machines would occupy a significant amount of usable space, making multi-drum washing machines a promising option. Choosing a twin-drum washer-dryer can meet these needs, effectively controlling costs and resolving issues of energy, water, and space waste. A well-designed twin-drum system, arranged vertically, saves space, but this introduces challenges related to power consumption control. Furthermore, the inherent vibration of front-loading washing machines during spin-drying is particularly pronounced in twin-drum systems. Especially during simultaneous high-speed spin-drying, strong vibrations occur, severely impacting the machine's stability and lifespan.

[0004] Therefore, current twin-drum washing machines, considering the vibration issues during the spin cycle, are programmed so that the two drums cannot spin simultaneously; one drum can only begin spinning after the other has finished. However, this increases the washing and spin-drying time, reducing user convenience. When multiple drums need to spin-dry within the same timeframe, excessive vibration or noise caused by the spin cycle can easily damage the washing machine and further degrade the user experience. Furthermore, when multiple drums spin-dry simultaneously, the vibrations from each other can affect the eccentricity data being measured during the distribution detection of the drums, causing the obtained eccentricity data to become inaccurate.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a control method and a garment processing device. This invention addresses the resonance problem that occurs when multiple garment processing drums are simultaneously spinning. The dehydration eccentricity detection of the garment processing drums in this invention is divided into several levels corresponding to different dehydration speeds. The garment processing device controls the maximum dehydration speed of the upcoming processing drum based on the operating status of other processing drums, allowing different processing drums to perform dehydration at different speeds and avoiding overall resonance.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] The first objective of this invention is to provide a control method for a garment processing device, which includes at least two independently operating garment processing drums. When any one garment processing drum performs eccentricity detection during the dehydration process, the garment processing device controls the maximum dehydration speed of that garment processing drum based on the operating status of the other garment processing drums.

[0009] In a further embodiment, when any garment processing drum needs to perform eccentricity detection during the dehydration process, the garment processing device determines whether other garment processing drums are in dehydration or eccentricity detection mode. If so, the garment processing device controls the maximum dehydration speed of the garment processing drum based on the eccentricity values ​​detected by other garment processing drums.

[0010] In a further embodiment, the garment processing device determines the corresponding maximum dehydration speed based on the eccentricity values ​​detected by other garment processing drums, and controls the maximum dehydration speed of the garment processing drum that needs to perform the dehydration process to be different from the maximum dehydration speed of other garment processing drums that are in the dehydration state.

[0011] In a further embodiment, the eccentricity value of the garment processing drum corresponds to different dehydration speeds depending on the degree of eccentricity. The smaller the degree of eccentricity, the smaller the detected eccentricity value, and the larger the corresponding maximum allowable dehydration speed. When the detected eccentricity values ​​of other garment processing drums are smaller, and the corresponding maximum dehydration speeds are larger, the garment processing device controls the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process to be smaller.

[0012] In a further embodiment, when any garment processing drum needs to perform eccentricity detection during the dehydration process, if there are multiple garment processing drums in the dehydration state or in the eccentricity detection state, the garment processing device adjusts the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process based on the minimum value of the eccentricity detected by the multiple garment processing drums.

[0013] In a further proposed solution, when any garment processing drum is performing an eccentricity detection during the dehydration process, if the garment processing device determines that the eccentricity value of that garment processing drum is greater than the eccentricity value of normal dehydration, then the other garment processing drums in the dehydration state will continue to operate normally, and the garment processing device will control that garment processing drum to suspend operation or re-perform the eccentricity detection.

[0014] In a further embodiment, the eccentricity value of the garment processing drum includes four levels: a, b, c, and d, with the degree of eccentricity increasing in the order a < b < c < d; wherein, the maximum dehydration speed corresponding to the four levels a, b, c, and d are A, B, C, and D respectively, and the magnitude of the dehydration speed is A > B > C > D.

[0015] A further proposed solution is that when any garment processing drum needs to perform eccentricity detection during the dehydration process, if the eccentricity values ​​detected by other garment processing drums in the dehydration state are a / b / c / d, and their corresponding maximum dehydration speeds are A / B / C / D, then the garment processing device controls the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process to be D / C / B / A.

[0016] In a further embodiment, when any garment processing drum needs to perform eccentricity detection during the dehydration process, the garment processing device determines whether other garment processing drums are in dehydration or eccentricity detection mode. If not, the garment processing device controls that garment processing drum to perform eccentricity detection, and allows it to reach its corresponding maximum dehydration speed during the dehydration process.

[0017] It should be noted that the dehydration process in this invention can be a dehydration process during washing, a dehydration process during drying, or a dehydration process in other garment processing methods. A second objective of this invention is to provide a garment processing apparatus employing the control method described above.

[0018] The garment handling device of the present invention can be a washing machine, or a washer-dryer combo, etc.

[0019] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0020] 1. This invention addresses the resonance problem that occurs when multiple garment processing drums are simultaneously spinning. The dehydration eccentricity detection of the garment processing drums in this invention is divided into several levels corresponding to different dehydration speeds. The garment processing device controls the maximum dehydration speed of the upcoming processing drum based on the operating status of other processing drums, allowing different processing drums to perform dehydration at different speeds and avoiding overall resonance.

[0021] 2. The smaller the detected eccentricity value of other garment processing drums in the dehydration state, and the higher the corresponding maximum dehydration speed, the lower the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process, controlled by the garment processing device. Thus, the maximum dehydration speed of the garment processing drum about to perform dehydration differs significantly from the speed of the garment processing drum currently dehydrating, greatly reducing the probability of the two garment processing drums operating at the same frequency during dehydration. This significantly reduces resonance, noise, and improves the user experience.

[0022] 3. Furthermore, when multiple garment processing drums operate simultaneously, mutual interference can distort the eccentricity detection data. Determining the timing of eccentricity detection based on the operating status of other garment processing drums ensures the accuracy of the data. By determining whether other garment processing drums are in the dehydration process, if they are all in the dehydration process, this state will not affect the eccentricity value, and eccentricity detection can be directly performed on the garment processing drum to be tested, ensuring the accuracy of the data.

[0023] 4. When the clothing processing drum in the dehydration process is in an unstable operating state, adjust the clothing processing drum in the dehydration process to a stable operating state before performing eccentricity detection on the clothing processing drum to be tested, so as to quickly complete the eccentricity detection.

[0024] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0025] The accompanying drawings, as part of this invention, are used to provide a further understanding of the invention. The illustrative embodiments and descriptions of the invention are used to explain the invention, but do not constitute an undue limitation of the invention. Obviously, the drawings described below are merely some embodiments, and those skilled in the art can obtain other drawings based on these drawings without creative effort. In the drawings:

[0027] Figure 2 This is a flowchart of the control method of the clothing processing device according to Embodiment 2 of the present invention;

[0028] Figure 3 This is a flowchart of the control method of the clothing processing device according to Embodiment 3 of the present invention.

[0029] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] Example 1

[0032] like Figure 1 As shown, this embodiment provides a control method for a clothing processing device. The clothing processing device includes at least two independently operating clothing processing drums. When any one clothing processing drum performs eccentricity detection during the dehydration process, the clothing processing device controls the maximum dehydration speed of that clothing processing drum according to the operating status of the other clothing processing drums.

[0033] For garment processing devices with multiple garment processing drums, significant resonance can easily occur when multiple drums are spinning simultaneously. In this embodiment, when any one garment processing drum is about to begin the spinning process, it does not immediately perform eccentricity detection and spinning. Instead, it first detects the operating status of the other garment processing drums and uses this information to control the maximum spinning speed of that drum. This allows different drums to spin at different speeds, avoiding resonance between the multiple drums and the entire device, thus reducing noise.

[0034] It should be noted that the dehydration process in this invention can be the dehydration process in the washing process, the dehydration process in the drying process, or the dehydration process in other clothing treatment methods.

[0035] In a further embodiment, when any garment processing drum needs to perform eccentricity detection during the dehydration process, the garment processing device determines whether other garment processing drums are in dehydration or eccentricity detection mode. If so, the garment processing device controls the maximum dehydration speed of the garment processing drum based on the eccentricity values ​​detected by other garment processing drums.

[0036] During the dehydration process, the garment processing drum of the garment processing device undergoes eccentricity detection. The data from this detection determines the distribution of the garments within the drum, thus facilitating dehydration. In this embodiment, the eccentricity detection during dehydration is divided into several levels corresponding to different dehydration speeds. A smaller degree of eccentricity corresponds to a higher dehydration speed, while a larger degree of eccentricity results in a lower dehydration speed, as detailed in the table below.

[0037] Table 1. Dehydration speeds corresponding to different eccentric distributions.

[0038]

[0039] In a further embodiment, the garment processing device determines the corresponding maximum dehydration speed based on the eccentricity values ​​detected by other garment processing drums, and controls the maximum dehydration speed of the garment processing drum that needs to perform the dehydration process to be different from the maximum dehydration speed of other garment processing drums that are in the dehydration state.

[0040] The detected eccentricity values ​​of other garment processing drums correspond to specific spin-drying speeds. The garment processing device controls the spin-drying speed of the drum about to undergo spin-drying based on the eccentricity value of the drum currently in the spin-drying state—that is, based on its corresponding allowable spin-drying speed. This allows the spin-drying speeds of different drums to be controlled within different ranges. The maximum spin-drying speed of the drum undergoing eccentricity detection during the spin-drying process differs from the maximum spin-drying speeds of other drums currently in the spin-drying state. This avoids or reduces situations where different drums are vibrating at the same frequency, reducing the probability of resonance, decreasing overall vibration of the garment processing device, and reducing noise.

[0041] In a further embodiment, the eccentricity value of the garment processing drum corresponds to different dehydration speeds depending on the degree of eccentricity. The smaller the degree of eccentricity, the smaller the detected eccentricity value, and the larger the corresponding maximum allowable dehydration speed. When the detected eccentricity values ​​of other garment processing drums are smaller, and the corresponding maximum dehydration speeds are larger, the garment processing device controls the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process to be smaller.

[0042] The eccentricity value detected during the eccentricity distribution detection of the garment processing drum reflects the degree of eccentricity of the garment processing drum. The smaller the degree of eccentricity, the smaller the detected eccentricity value, and the higher the corresponding maximum allowable spin speed; the larger the degree of eccentricity, the larger the detected eccentricity value, and the lower the corresponding maximum allowable spin speed.

[0043] In a garment processing device with multiple garment processing drums, when one drum X needs to be dehydrated, a stage check is first performed on the other drums. If a garment processing drum Y is currently distributing or dehydrating, the range of values ​​and corresponding maximum speeds of the successfully detected distribution eccentricity are first confirmed. Then, the maximum achievable dehydration speed and the range of allowable eccentricity values ​​for the currently distributing garment processing drum are adjusted. The garment processing device controls the difference in dehydration speed between garment processing drums X and Y to be as large as possible, or kept within a certain range of difference. This avoids or reduces situations where different garment processing drums are at the same vibration frequency, reducing the probability of resonance, reducing the overall vibration of the garment processing device, and reducing noise.

[0044] In a further embodiment, when any garment processing drum needs to perform eccentricity detection during the dehydration process, if there are multiple garment processing drums in the dehydration state or in the eccentricity detection state, the garment processing device adjusts the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process based on the minimum value of the eccentricity detected by the multiple garment processing drums.

[0045] When the garment processing device has three or more garment processing drums, if two or more drums are in the spin-drying or eccentricity detection state, the device compares the detected eccentricity values ​​of the multiple drums, obtains the minimum eccentricity value, and then adjusts the spin-drying speed of the drum to be spin-dryed based on this minimum eccentricity value. In this way, the spin-drying speed of the drum about to be spin-dryed can be different from that of the other drums, thereby avoiding resonance among the multiple drums and reducing the overall noise of the garment processing device.

[0046] In a further proposed solution, when any garment processing drum is performing an eccentricity detection during the dehydration process, if the garment processing device determines that the eccentricity value of that garment processing drum is greater than the eccentricity value of normal dehydration, then the other garment processing drums in the dehydration state will continue to operate normally, and the garment processing device will control that garment processing drum to suspend operation or re-perform the eccentricity detection.

[0047] Before spin-drying, the garment processing drums of the garment processing device undergo an eccentricity distribution detection. Spin-drying can only commence if the detection is successful and the eccentricity is within the permissible range. If any garment processing drum experiences excessive eccentricity during eccentricity detection, exceeding the normal eccentricity range for spin-drying, the garment processing device will not directly adjust the spin-drying speed of that drum based on the eccentricity values ​​of the other drums. Instead, it will maintain the normal operation of the other drums, pause the process for that drum, or re-detect the eccentricity. Once the detection is successful and the eccentricity is within the normal range, the spin-drying speed will then be adjusted based on the eccentricity values ​​of the other drums.

[0048] As one specific implementation, the eccentricity value of the garment processing drum includes four levels: a, b, c, and d. The degree of eccentricity and the eccentricity value are in ascending order: a < b < c < d. The maximum spin speeds corresponding to the four levels a, b, c, and d are A, B, C, and D, respectively, and the spin speeds are in the order: A > B > C > D.

[0049] Table 2 shows the dehydration speeds corresponding to different eccentric distributions.

[0050]

[0051] Note: a <b<c<d A> B>C>D

[0052] In this scheme, the eccentricity value of the garment processing drum and the spin speed are divided into four levels, but it can also be divided into two, three, five or more levels, without limitation. This scheme is only one implementation method. Among them, a, b, c, d and A, B, C, D can all be a dividing point value or a range interval.

[0053] A further proposed solution is that when any garment processing drum needs to perform eccentricity detection during the dehydration process, if the eccentricity values ​​detected by other garment processing drums in the dehydration state are a / b / c / d, and their corresponding maximum dehydration speeds are A / B / C / D, then the garment processing device controls the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process to be D / C / B / A.

[0054] like Figure 1 As shown, the situations can be specifically divided into the following four categories:

[0055] Case 1: When any garment processing drum needs to perform the eccentricity detection of the dehydration process, when the eccentricity value detected by other garment processing drums in the dehydration state is a, the corresponding maximum dehydration speed is A. Then the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process controlled by the garment processing device is D.

[0056] Case 2: When any garment processing drum needs to perform the eccentricity detection of the dehydration process, when the eccentricity value detected by other garment processing drums in the dehydration state is b, the corresponding maximum dehydration speed is B. Then the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process is C.

[0057] Case 3: When any garment processing drum needs to perform the eccentricity detection of the dehydration process, when the eccentricity value detected by other garment processing drums in the dehydration state is c, the corresponding maximum dehydration speed is C. Then the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process is B.

[0058] Case 4: When any garment processing drum needs to perform eccentricity detection during the dehydration process, if the eccentricity value detected by other garment processing drums in the dehydration state is d, the corresponding maximum dehydration speed is D. Then, the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process is A.

[0059] In a further embodiment, when any garment processing drum needs to perform eccentricity detection during the dehydration process, the garment processing device determines whether other garment processing drums are in dehydration or eccentricity detection mode. If not, the garment processing device controls that garment processing drum to perform eccentricity detection, and allows it to reach its corresponding maximum dehydration speed during the dehydration process.

[0060] When any one garment processing drum needs to perform the eccentricity detection during the spin-drying process, while the other garment processing drums are in the washing or rinsing state, the problem of resonance caused by multiple garment processing drums spinning simultaneously will not occur when that particular drum performs the spin-drying process alone. Therefore, the garment processing device controls the garment processing drum to perform normal eccentricity detection distribution and spin-dry normally, allowing it to reach its corresponding maximum spin-drying speed during the spin-drying process.

[0061] Example 2

[0062] like Figures 2-3 As shown, this embodiment is a further limitation of Embodiment 1, providing a control method for a clothing processing device. The clothing processing device includes at least two clothing processing tanks. When any one of the clothing processing tanks is eccentric during the dehydration process, the clothing processing device determines the timing for eccentric detection of that clothing processing tank based on the operating status of the other clothing processing tanks.

[0063] During the dehydration process, garment processing devices perform eccentricity detection to determine the distribution of clothes within the processing drum. For devices with multiple processing drums, if other drums are also operating, the vibrations from these drums can cause deviations and distortions in the eccentricity detection data, leading to errors in the device's assessment of the garment distribution. Therefore, this invention utilizes the operating status of other processing drums to determine when to perform eccentricity detection on a given drum. If the operating status of other drums does not affect the eccentricity detection data, the detection is performed directly on that drum; otherwise, it is performed only when the operating status of other drums no longer influences the eccentricity detection data.

[0064] In a further embodiment, when any garment processing drum is being dehydrated, the garment processing device determines whether other garment processing drums are in the dehydration process. If not, it performs an eccentricity detection on that garment processing drum. If so, it determines the timing for performing an eccentricity detection on that dehydration drum based on the dehydration stage of the garment processing drum in the dehydration process.

[0065] When the garment processing drum is not in a dehydration process (e.g., during washing and rinsing), the vibration is small, which has little impact on the eccentricity detection value of the garment processing drum that is being tested for eccentricity, and will not cause distortion of the eccentricity data. Therefore, if other garment processing drums are not in a dehydration process, the garment processing device will directly perform eccentricity detection on that garment processing drum. If other garment processing drums are in a dehydration process, further judgment is required based on the dehydration stage.

[0066] A further approach involves determining the timing for eccentricity detection of the dehydration drum based on its current stage in the dehydration process, including:

[0067] The dehydration process of the garment processing tub includes at least one stable operation phase that does not interfere with the eccentricity detection data of other garment processing tubs. The garment processing device determines whether the garment processing tub in the dehydration process is in a stable operation phase. If it is, then the garment processing tub to be tested for eccentricity is tested. If not, then the garment processing tub in the dehydration process is adjusted to a stable operation phase / after the garment processing tub in the dehydration process has reached a stable operation phase, then the garment processing tub to be tested for eccentricity is tested.

[0068] The dehydration process includes at least one stable operating phase. During this phase, the garment processing drum experiences minimal vibration and does not resonate with other garment processing drums. This has minimal impact on the eccentricity data of the garment processing drum to be tested, preventing data distortion. Therefore, performing eccentricity testing on this particular garment processing drum while all other drums are in stable operating phases ensures accurate eccentricity detection data.

[0069] Example 3

[0070] This embodiment is a further limitation of Embodiment 2. In this embodiment, the stable operation stage includes an eccentricity detection stage and / or a high-speed dehydration stage. The clothing processing device determines whether the clothing processing drum in the dehydration process is in the eccentricity detection stage / high-speed dehydration stage. If so, the eccentricity detection is performed on the clothing processing drum to be eccentrically detected. If not, the clothing processing device adjusts the clothing processing drum in the dehydration process to the eccentricity detection stage / high-speed dehydration stage before performing the eccentricity detection on the clothing processing drum to be eccentrically detected.

[0071] During the eccentricity detection and high-speed dehydration stages, the garment processing drum experiences minimal vibration, minimizing its impact on other garment processing drums. When a garment processing drum is in the eccentricity detection / high-speed dehydration stage, eccentricity detection can be performed directly on that drum, ensuring the accuracy of the eccentricity data. Conversely, if the drum is not in the eccentricity detection / high-speed dehydration stage, it should be adjusted before performing eccentricity detection on the desired drum. This approach ensures more accurate results and faster eccentricity detection.

[0072] In a further solution, before the laundry treatment device adjusts the laundry treatment tub in the dehydration process to the high-speed dehydration stage, the laundry treatment device judges whether it can be accelerated to the high-speed dehydration stage according to the eccentricity data of the laundry treatment tub in the dehydration process. If yes, the laundry treatment tub in the dehydration process is adjusted to the high-speed dehydration stage; if no, it is adjusted to the eccentricity detection stage.

[0073] If the laundry in the laundry treatment tub is poorly distributed, its eccentricity is large, which will cause tub collision during speed increase, so it cannot enter the high-speed dehydration stage. Before the laundry treatment device adjusts the laundry treatment tub in the dehydration process to the high-speed dehydration stage, it judges whether it can be accelerated to the high-speed dehydration stage according to the eccentricity data of the laundry treatment tub in the dehydration process. If the laundry treatment tub in the dehydration process cannot be accelerated to the high-speed dehydration stage, it is adjusted to the eccentricity detection stage, and then the eccentricity detection is performed on the laundry treatment tub to be subjected to eccentricity detection. If the laundry treatment tub in the dehydration process can be accelerated to the high-speed dehydration stage, it is adjusted to the high-speed dehydration stage, and then the eccentricity detection is performed on the laundry treatment tub to be subjected to eccentricity detection.

[0074] In a further solution, the specific method for judging whether the laundry treatment tub in the dehydration process can be accelerated to the high-speed dehydration stage according to its eccentricity data is as follows:

[0075] The laundry treatment device presets a plurality of eccentricity detection value ranges and the corresponding results of being able / unable to be accelerated to the high-speed dehydration stage in one-to-one correspondence. The laundry treatment device obtains the corresponding result of being able / unable to be accelerated to the high-speed dehydration stage according to the eccentricity detection value range where the eccentricity data of the laundry treatment tub in the dehydration process is located.

[0076] For example, the laundry treatment device presets that when the eccentricity detection value range is less than a, the laundry treatment tub can be accelerated to the high-speed dehydration stage; and presets that when the eccentricity detection value range is greater than or equal to a, the laundry treatment tub cannot be accelerated to the high-speed dehydration stage. If the eccentricity data of the laundry treatment tub in the dehydration process is b and b < a, then it can be accelerated to the high-speed dehydration stage.

[0077] In a further solution, the dehydration process of the laundry treatment tub further includes a medium-speed dehydration stage, the medium-speed dehydration stage does not belong to the stable operation stage, and if the laundry treatment tub in the dehydration process is in the medium-speed dehydration stage, the laundry treatment device adjusts the laundry treatment tub to the eccentricity detection stage / high-speed dehydration stage.

[0078] A specific control method for a laundry treatment device, the laundry treatment device comprising a first laundry treatment tub and a second laundry treatment tub, the control method comprising the following steps, taking a washing machine as an example as shown in Figure 2 the following:

[0079] When the first garment processing drum is eccentric during the dehydration process, the garment processing device determines whether the second garment processing drum is in the dehydration process. If not, it directly performs eccentricity detection on the first garment processing drum. After the detection is completed, it speeds up the dehydration process. If not, it executes S2.

[0080] The S2 garment processing device determines whether the second garment processing drum is in the eccentricity detection stage, the medium-speed dehydration stage, or the high-speed dehydration stage.

[0081] If the second garment processing drum is in the eccentricity detection stage, then the first garment processing drum will be checked for eccentricity. After both garment processing drums have completed the eccentricity detection, both will accelerate their dehydration process.

[0082] If the second garment processing drum is in the medium-speed dehydration stage, determine whether it can be accelerated to the high-speed dehydration stage based on the eccentricity value of the second garment processing drum. If yes, adjust the second garment processing drum to the high-speed dehydration stage and then perform eccentricity detection on the first garment processing drum. If no, adjust the second garment processing drum to the eccentricity detection stage and then perform eccentricity detection on the first garment processing drum. After the detection is completed, dehydration is performed.

[0083] If the second garment processing drum is in the high-speed dehydration section, then the first garment processing drum is subjected to an eccentricity detection, and dehydration is carried out after the detection is completed.

[0084] Example 4

[0085] This embodiment is a further limitation of Embodiment 2. The stable operation stage includes an eccentricity detection stage. The clothing processing device determines whether the clothing processing bucket in the dehydration stage is in the eccentricity detection stage. If it is, the clothing processing bucket to be eccentrically detected is subjected to eccentricity detection. If not, the clothing processing bucket in the dehydration stage is adjusted to the eccentricity detection stage or, after it reaches the eccentricity detection stage, the clothing processing device performs eccentricity detection on the clothing processing bucket to be eccentrically detected.

[0086] When a garment processing bin is in the eccentricity detection stage, it has little impact on the eccentricity detection data of other garment processing bins. When a garment processing bin is in the eccentricity detection stage, the eccentricity detection is performed directly on the garment processing bin to be detected. Otherwise, all other bins are adjusted to the eccentricity detection stage so that the garment processing bin to be detected can be detected for eccentricity.

[0087] The garment processing device includes a first garment processing tank and a second garment processing tank. The garment processing device determines whether the second garment processing tank, which is in the dehydration process, is in the eccentricity detection stage. If it is, the device performs eccentricity detection on the first garment processing tank. If it is not, the device adjusts the second garment processing tank to the eccentricity detection stage and then performs eccentricity detection on the first garment processing tank.

[0088] Furthermore, a specific control method for a clothing processing device is provided. The clothing processing device includes a first clothing processing tub and a second clothing processing tub. The control method includes the following steps, taking a washing machine as an example: Figure 3 As shown:

[0089] When the first garment processing drum is eccentric during the dehydration process, the garment processing device determines whether the second garment processing drum is in the dehydration process. If not, it directly performs eccentricity detection on the first garment processing drum. After the detection is completed, the rotation speed is increased to perform dehydration. If not, it executes S2.

[0090] The S2 clothing processing device determines whether the second clothing processing bin is in the eccentricity detection stage.

[0091] If so, then perform an eccentricity detection on the first garment processing drum, and after both garment processing drums have completed the eccentricity detection, increase their rotation speed to perform dehydration.

[0092] If not, adjust the second garment processing tub to the eccentricity detection stage, then perform an eccentricity detection on the first garment processing tub, and then proceed with the dehydration process after the detection is completed.

[0093] Example 5

[0094] This implementation further defines Embodiment 2. The stable operation phase includes an eccentricity detection phase and / or a high-speed dehydration phase. The garment processing device determines whether the garment processing tub in the dehydration process is in the eccentricity detection phase / high-speed dehydration phase. If so, the garment processing tub to be eccentrically detected is subjected to eccentricity detection. If not, the garment processing tub to be eccentrically detected is controlled to be in a waiting state. After the garment processing tub in the dehydration process reaches the eccentricity detection phase / high-speed dehydration phase, the garment processing tub to be eccentrically detected is subjected to eccentricity detection.

Claims

1. A control method for a garment handling device, characterized in that, The garment processing unit includes at least two independently operating garment processing tanks. When any garment processing drum is being checked for eccentricity during the dehydration process, the garment processing device determines the timing for checking the eccentricity of that garment processing drum based on the operating status of the other garment processing drums. During the eccentricity detection of any garment processing drum in the dehydration process, the garment processing device determines whether other garment processing drums are in the dehydration process. If not, it performs eccentricity detection on that garment processing drum. If so, it determines the timing of eccentricity detection for that garment processing drum based on its current dehydration stage, including: The dehydration process of the garment processing tank includes at least one stable operation phase that does not interfere with the eccentricity detection data of other garment processing tanks. The garment processing device determines whether the garment processing tank in the dehydration process is in a stable operation phase. If it is, then the garment processing tank to be tested for eccentricity is tested for eccentricity. If not, then the garment processing tank in the dehydration process is adjusted to a stable operation phase / after the garment processing tank in the dehydration process has reached a stable operation phase, then the garment processing tank to be tested for eccentricity is tested for eccentricity. When any garment processing drum needs to perform eccentricity detection during the dehydration process, the garment processing device determines whether other garment processing drums are in the dehydration state or the eccentricity detection state. If so, the garment processing device controls the maximum dehydration speed of the garment processing drum based on the eccentricity values ​​detected by other garment processing drums; and controls the maximum dehydration speed of the garment processing drum that needs to perform eccentricity detection during the dehydration process to be different from the maximum dehydration speed of other garment processing drums that are in the dehydration state. The eccentricity value of the garment processing drum corresponds to different dehydration speeds depending on the degree of eccentricity. The smaller the degree of eccentricity, the smaller the detected eccentricity value, and the larger the corresponding maximum allowable dehydration speed. When the detected eccentricity values ​​of other garment processing drums are smaller and the corresponding maximum dehydration speeds are larger, the garment processing device controls the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process to be smaller. The eccentricity value of the garment processing drum includes four levels: a, b, c, and d. The degree of eccentricity increases from small to large in the order of a < b < c < d. The maximum spin speed corresponding to the four levels a, b, c, and d is A, B, C, and D, respectively, and the spin speed is A > B > C > D. When any garment processing drum needs to perform eccentricity detection during the dehydration process, if the eccentricity values ​​detected by other garment processing drums in the dehydration state are a / b / c / d, and their corresponding maximum dehydration speeds are A / B / C / D, then the garment processing device controls the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process to be D / C / B / A.

2. The control method for a garment handling device according to claim 1, characterized in that, When any garment processing drum needs to perform eccentricity detection during the dehydration process, if there are multiple garment processing drums in the dehydration state or eccentricity detection state, the garment processing device adjusts the maximum allowable dehydration speed of the garment processing drum that needs to perform the dehydration process based on the minimum value of the eccentricity detected by the multiple garment processing drums.

3. The control method for a garment processing device according to claim 1, characterized in that, When any garment processing drum performs an eccentricity detection during the dehydration process, if the garment processing device determines that the eccentricity value of the garment processing drum is greater than the eccentricity value of normal dehydration, then the other garment processing drums in the dehydration state will continue to operate normally, and the garment processing device will control the garment processing drum to suspend operation or re-perform the eccentricity detection.

4. A control method for a garment handling device according to any one of claims 1-3, characterized in that, When any garment processing drum needs to perform eccentricity detection during the dehydration process, the garment processing device determines whether other garment processing drums are in dehydration or eccentricity detection mode. If not, the garment processing device controls that garment processing drum to perform eccentricity detection, and allows it to reach its corresponding maximum dehydration speed during the dehydration process.

5. A garment handling apparatus employing the control method as described in any one of claims 1-4.
