Description

Technical Field

[0001] This application relates to the field of fabric processing equipment technology, and in particular to a control method for fabric processing equipment, fabric processing equipment, and electronic equipment. Background Technology

[0002] With the improvement of people's living standards, washing machines have become one of the essential household appliances. In order to meet users' needs for washing efficiency, twin-tub washing machines have emerged. By setting up two independent washing drums, they can process different types of clothes at the same time, greatly improving washing efficiency.

[0003] Currently, twin-tub washing machines on the market typically consist of two washing drums arranged vertically or horizontally, each capable of independently running washing, rinsing, and spin-drying programs. During the spin-drying process, the washing drums need to undergo a speed increase from low to high to achieve effective dehydration. Existing technologies primarily employ the following methods for controlling the spin-drying process in twin-tub washing machines:

[0004] A common dehydration control method is to calculate a reference target rotation speed based on the fabric's eccentricity and weight, and then control the rotation of the treatment drum according to the reference target rotation speed to improve dehydration efficiency.

[0005] Another approach is a control strategy for multi-drum washing machines that are spinning simultaneously. When at least two washing drums in a multi-drum washing machine are in the spin-drying stage at the same time, the timing of entering the high-speed spin-drying stage of at least one washing drum is delayed, so that the washing drums are not in the high-speed spin-drying maintenance stage at the same time, thereby reducing the resonance of the whole machine and reducing the overall amplitude of the washing machine during spin-drying.

[0006] In addition, some technical solutions focus on spray control during the spin-drying process. For example, the spray flow rate for cleaning can be controlled according to the spin-drying progress, and the spray water flow rate can be adjusted according to different spin speed stages to reduce detergent residue on clothes and reduce eccentric vibration of the washing machine.

[0007] In summary, existing twin-tub washing machines still have the following problems during the simultaneous spin-drying process:

[0008] 1. When twin-tub washing machines are working simultaneously, especially when both washing tubs enter the spin-drying speed-up operation stage at the same time, the current flowing through the controller components is large, which makes the selection of controller circuits demanding and costly.

[0009] 2. When a twin-tub washing machine spins water simultaneously, the speed increase of the two tubs may affect each other due to motor power limitations, resulting in a longer spin-drying time and impacting the user experience.

[0010] 3. During the dehydration process, especially during the speed-up operation phase, the operating current is large when both motors are working simultaneously, requiring larger common-mode inductors and PFC inductors, which increases product cost and size.

[0011] 4. Although there are existing methods for controlling the spin-drying of multi-drum washing machines, most of them focus on reducing vibration and noise, and lack effective solutions for controlling current peak and improving energy efficiency. Summary of the Invention

[0012] In view of this, this application provides a control method for a fabric processing device, a fabric processing device, and an electronic device to solve the problem that existing fabric processing devices are prone to resonance when multiple tubes work simultaneously, resulting in significant noise and a poor user experience.

[0013] A first aspect of this application provides a control method for a fabric processing device, the fabric processing device including a first fabric processing cylinder and a second fabric processing cylinder arranged vertically, the first fabric processing cylinder being located on the upper side and the second fabric processing cylinder being located on the lower side, the control method including:

[0014] The dewatering processes of both the first and second fabric treatment cylinders are equipped with multiple speed-up operation stages and multiple stable operation stages;

[0015] During the simultaneous execution of the dewatering process by the first fabric processing drum and the second fabric processing drum, the first fabric processing drum and the second fabric processing drum are controlled to alternately perform the speed-up operation phase and the stable operation phase.

[0016] The control priority of the first fabric treatment cylinder executing the dewatering command is higher than the control priority of the second fabric treatment cylinder executing the dewatering command.

[0017] In some embodiments, the first fabric treatment cylinder and the second fabric treatment cylinder are controlled to start sequentially when a dewatering command is executed.

[0018] In some embodiments, when one of the first fabric treatment tube and the second fabric treatment tube completes the dehydration process, the fabric treatment tube that has not completed the dehydration process is directly subjected to subsequent dehydration treatment.

[0019] In some embodiments, the control method further includes:

[0020] In response to an instruction that the first fabric processing cylinder and the second fabric processing cylinder simultaneously execute the dewatering program, an eccentricity detection is performed on the fabric processing cylinder that executes the dewatering instruction first to determine the maximum rotational speed;

[0021] The target speed for each acceleration phase is determined based on the maximum speed.

[0022] The fabric processing drum that prioritizes the dehydration command is controlled to increase its speed in stages according to the target speed of each speed-up operation stage. After reaching the corresponding target speed in each speed-up operation stage, the fabric processing drum is controlled to maintain the target speed and operate stably to complete the stable operation stage.

[0023] In some embodiments, controlling the first fabric treatment cylinder and the second fabric treatment cylinder to alternately perform an acceleration operation phase and a stable operation phase includes:

[0024] Obtain the rotational speed information of the fabric processing drum during the acceleration phase;

[0025] When it is determined that the fabric processing drum in the speed-up operation stage has reached the target speed of the speed-up operation stage, the fabric processing drum is controlled to maintain stable operation at the target speed.

[0026] The instruction was given to increase the speed of another fabric processing cylinder.

[0027] In some embodiments, obtaining the rotational speed information of the fabric processing drum during the acceleration phase includes:

[0028] Obtain the operating status parameters of the drive motor of the fabric processing cylinder in the speed-up operation phase;

[0029] Based on the operating status parameters, determine whether the fabric processing cylinder in the speed-up operation phase has reached the target speed of the speed-up operation phase and is operating stably.

[0030] In some embodiments, determining whether the fabric processing cylinder in the speed-up operation phase has reached the target speed of the speed-up operation phase and is operating stably based on the working state parameters includes:

[0031] When it is determined that the real-time power of the drive motor of the fabric processing drum that drives the speed-up operation is within the set power range within a set time, it is then determined whether the speed-up operation of the fabric processing drum has reached the target speed of the speed-up operation stage and is operating stably.

[0032] In some embodiments, during the plurality of speed-up operation phases, the rotational speed in the preceding speed-up operation phase is 30% to 60% of the rotational speed in the subsequent speed-up operation phase;

[0033] Alternatively, the rotational speed in the later acceleration phase may be an integer multiple of the rotational speed in the earlier acceleration phase.

[0034] In some embodiments, controlling the first fabric treatment cylinder and the second fabric treatment cylinder to alternately perform an acceleration operation phase and a stable operation phase includes:

[0035] While one of them is in the stable operation phase, the other is controlled to perform any of the acceleration operation phases, each of the acceleration operation phases including one or more acceleration processes.

[0036] The second aspect of this application provides a fabric processing device, which is controlled by the control method of the fabric processing device as described in the first aspect. The fabric processing device includes a first fabric processing cylinder, a second fabric processing cylinder, and a control module.

[0037] The control module includes an intermediate control unit, a first control board corresponding to the first fabric processing cylinder, and a second control board corresponding to the second fabric processing cylinder.

[0038] The first control board and the second control board are respectively used to acquire the operating parameters of the corresponding fabric processing cylinder;

[0039] The intermediate control unit is used to receive the operating parameters of the two control boards and provide corresponding control commands to the two control boards based on the operating parameters, so as to perform corresponding control on the first fabric treatment tube or the second fabric treatment tube.

[0040] Both the first fabric treatment cylinder and the second fabric treatment cylinder are equipped with a dewatering program, and each of the dewatering programs has multiple speed-up operation stages and multiple stable operation stages;

[0041] The first fabric treatment tube and the second fabric treatment tube are configured such that, during the simultaneous execution of the dewatering process by the first fabric treatment tube and the second fabric treatment tube, the first fabric treatment tube and the second fabric treatment tube are controlled to alternately perform an acceleration operation phase and a stable operation phase.

[0042] In some embodiments, the first fabric treatment tube and the second fabric treatment tube are arranged vertically, wherein the first fabric treatment tube is located on the upper side and the second fabric treatment tube is located on the lower side.

[0043] A third aspect of this application provides an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the control method for the fabric processing device as described in the first aspect.

[0044] Compared with the prior art, the main advantages of this application are:

[0045] In the control method, fabric processing equipment, and electronic equipment of this application, the control method of the fabric processing equipment includes multiple acceleration operation stages and multiple stable operation stages in the dewatering programs of both the first and second fabric processing cylinders. During the simultaneous execution of the dewatering program by the first and second fabric processing cylinders, the first and second fabric processing cylinders are controlled to alternate between the acceleration operation stage and the stable operation stage. The control priority of the first fabric processing cylinder executing the dewatering command is higher than that of the second fabric processing cylinder. By controlling the two fabric processing cylinders to alternate between the stable operation stage and the acceleration operation stage, the resonance and noise generated by the joint operation of the two motors can be effectively reduced. The operating current of the two motors can also be effectively reduced. Compared with the current flowing through the common mode inductor and PFC inductor when the two fabric processing cylinders are controlled to accelerate simultaneously, the current is smaller, and thus smaller common mode inductors and PFC inductors can be used. On the other hand, it can also effectively ensure and shorten the overall dewatering time, improving the user experience. Attached Figure Description

[0058] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. The singular forms “a,” “said,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0060] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0061] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0062] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, but should not be construed as limiting this application.

[0063] like Figure 1 As shown, the fabric processing device 100 includes two fabric processing cylinders, namely a first fabric processing cylinder and a second fabric processing cylinder arranged vertically. The first fabric processing cylinder is located on the upper side (i.e., upper cylinder 110), and the second fabric processing cylinder is located on the lower side (i.e., lower cylinder 120). In this example and the examples below, the upper cylinder 110 is used as the first fabric processing cylinder and the lower cylinder 120 is used as the second fabric processing cylinder for illustration.

[0064] The upper cylinder 110 is driven to rotate by a first motor 111, and the lower cylinder 120 is driven to rotate by a second motor 121. The upper cylinder 110 and the lower cylinder 120 are controlled by a first control board 112 and a second control board 122, respectively. Both control boards (i.e., the first control board 112 and the second control board 122) are data-connected to an intermediate control unit 130. The intermediate control unit 130 serves as an information exchange station between the upper cylinder 110 and the lower cylinder 120, facilitating better logical control of the upper cylinder 110 and the lower cylinder 120 via the first control board 112 and the second control board 122, respectively.

[0065] In practical use, the first control board 112 is connected to the upper cylinder 110 to obtain its operating parameters. The second control board 122 is connected to the lower cylinder 120 to obtain its operating parameters. The intermediate control unit 130 receives the operating parameters of the upper cylinder 110 and the lower cylinder 120, and sends corresponding control commands to the first control board 112 and the second control board 122 based on these parameters, so as to achieve better and more precise control over the upper cylinder 110 and the lower cylinder 120.

[0066] like Figures 1 to 5As shown, an exemplary embodiment of this application provides a control method for a fabric processing device. This control method can be applied to a fabric processing device. The fabric processing device includes a first fabric processing cylinder and a second fabric processing cylinder arranged vertically, both capable of dewatering the fabric.

[0067] The fabric processing equipment may include, but is not limited to, washing machines, which may include, but are not limited to, washer-dryer combos, etc. For example, the washing machine may be a front-loading washing machine or a top-loading washing machine with drying or washing functions, and of course, it may also be other types of fully automatic washing machines.

[0068] In this example and the examples below, the fabric handling equipment is described using a twin-drum washing machine as an example. The twin-drum washing machine (fabric handling equipment) includes two fabric handling drums arranged vertically, with the first fabric handling drum located on the upper side and the second fabric handling drum located on the lower side. The two fabric handling drums can operate independently or simultaneously. The two fabric handling drums are used to wash fabrics in spin-drying mode, wherein the first fabric handling drum located on the upper side is the upper drum, and the second fabric handling drum located on the lower side is the lower drum.

[0069] Specifically, the control method for the fabric processing equipment includes the following steps:

[0070] Step S100: The dewatering processes of both the first and second fabric treatment drums are equipped with multiple speed-up operation stages and multiple stable operation stages.

[0071] Step S200: During the simultaneous execution of the dewatering process by the first fabric processing cylinder and the second fabric processing cylinder, the first fabric processing cylinder and the second fabric processing cylinder are controlled to alternately perform the speed-up operation phase and the stable operation phase, wherein the control priority of the first fabric processing cylinder executing the dewatering command is greater than the control priority of the second fabric processing cylinder executing the dewatering command.

[0072] Specifically, the first and second fabric processing drums are controlled to start sequentially when the dewatering command is executed. That is, the first fabric processing drum can be started first, followed by the second fabric processing drum. Alternatively, the second fabric processing drum can be started first, followed by the first fabric processing drum.

[0073] In one example, the two fabric processing cylinders can also be controlled to start sequentially based on their start-up priorities. For instance, if the start-up priority of the first fabric processing cylinder is higher than that of the second fabric processing cylinder, the first fabric processing cylinder is started first. Then, when the first fabric processing cylinder is in a stable operating phase, the second fabric processing cylinder is controlled to enter the speed-up operating phase to increase its speed.

[0074] For example, when the start-up priority of the second fabric processing cylinder is higher than that of the first fabric processing cylinder, the second fabric processing cylinder is started first. Then, when the second fabric processing cylinder is in a stable operating phase, the first fabric processing cylinder is controlled to enter the speed-up operating phase to increase its speed.

[0075] In a specific example, the first fabric processing drum has a higher startup priority than the second fabric processing drum. That is, when both fabric processing drums need to perform the dewatering process simultaneously, the first fabric processing drum is started first, that is, the fabric on the upper drum is dewatered first. Once the upper drum is in a stable operating phase, the lower drum is then controlled to increase its speed.

[0076] In this example, by controlling the two fabric processing drums to operate alternately during the stable operation phase and the speed-up operation phase, the resonance and noise generated by the joint operation of the two motors can be effectively reduced. This also effectively reduces the operating current of the two motors, resulting in a smaller current flowing through the common mode inductor and PFC inductor compared to when the two fabric processing drums are controlled to speed up simultaneously. This allows the use of smaller common mode inductors and PFC inductors. On the other hand, it also effectively ensures and shortens the overall dehydration time, improving the user experience.

[0077] like Figures 1 to 5 As shown, in some embodiments, when one of the first fabric treatment tube and the second fabric treatment tube completes the dehydration process, the fabric treatment tube that has not completed the dehydration process directly undergoes subsequent dehydration treatment.

[0078] In this example, by having two fabric processing drums alternately run in the acceleration and stabilization phases, both drums can quickly complete the dehydration process of the fabrics inside their respective drums. This also effectively reduces the resonance and noise generated by the joint operation of the two motors, and reduces the operating current of the two motors, thereby improving the user experience.

[0079] like Figures 1 to 5 As shown, in some embodiments, when both drums need to execute the dehydration command simultaneously, the control method includes the following steps:

[0080] Step 1: In response to the instruction that the first and second fabric treatment drums simultaneously execute the dewatering program, eccentricity detection is performed on the fabric treatment drum that executes the dewatering instruction first to determine the maximum rotational speed. In this step, the upper drum (first fabric treatment drum) executes the dewatering command first.

[0081] Among them, the eccentricity detection method in the existing technology can be used to detect the eccentricity of the fabric treatment cylinder that prioritizes the dehydration command, which will not be elaborated here.

[0082] Step Two: Determine the target speed for each acceleration phase based on the maximum speed. In these acceleration phases, the speed in the earlier acceleration phase should be 30% to 60% of the speed in the later acceleration phase; or, the speed in the later acceleration phase should be an integer multiple of the speed in the earlier acceleration phase. For example, when the upper cylinder operates at a maximum speed of 1200 RPM, the acceleration can be planned in three phases: the first phase at 400 RPM, the second at 800 RPM, and the final phase at 1200 RPM, continuing until the end.

[0083] Step 3: Control the fabric processing drum that prioritizes the dehydration command to increase its speed in stages according to the target speed of each speed-up operation stage. After reaching the corresponding target speed in each speed-up operation stage, control the fabric processing drum to maintain the target speed and operate stably to complete the stable operation stage.

[0084] like Figures 1 to 5 As shown, in some embodiments, the process of controlling the first fabric treatment cylinder and the second fabric treatment cylinder to alternately perform the acceleration operation phase and the stable operation phase specifically includes:

[0085] First, obtain the rotational speed information of the fabric processing drum during the acceleration phase. To obtain this information, first acquire the operating status parameters of the drive motor of the fabric processing drum during the acceleration phase. Then, based on these parameters, determine whether the fabric processing drum has reached the target rotational speed for the acceleration phase and is operating stably.

[0086] Specifically, when it is determined that the real-time power of the drive motor of the fabric processing drum that drives the speed-up operation is within the set power range within a set time, it is determined that the fabric processing drum that drives the speed-up operation has reached the target speed of the speed-up operation stage and is running stably.

[0087] Secondly, when it is determined that the fabric processing drum in the speed-up operation stage has reached the target speed of the speed-up operation stage, the fabric processing drum is controlled to maintain stable operation at the target speed.

[0088] Then, another fabric processing cylinder was instructed to increase its speed.

[0089] In a specific example, the real-time power P1 of the first motor controlling the operation of the first fabric processing drum, collected by the first control board, is fed back to the intermediate control unit. The real-time power P1 received by the intermediate control unit for b consecutive seconds is a first value. This first value is a fixed value with an error range of m%, where m≤5. If this is the case, it is determined that the rotation speed of the first fabric processing drum has reached the stable rotation speed of the first stage, and the first fabric processing drum maintains the stable rotation speed of the first stage. Otherwise, the acceleration command is continued to be executed.

[0090] When the real-time power P1 of the first fabric processing tube remains at a fixed value for b consecutive seconds, the intermediate control unit can send an acceleration command to the second control board. The second fabric processing tube then begins to execute the acceleration command. The real-time power P2 of the second fabric processing tube collected by the second control board is fed back to the intermediate control unit. When the real-time power P2 of the second fabric processing tube received by the intermediate control unit for a consecutive seconds is a second value, and this second value is a fixed value with an error range of m%, where m≤5, the second fabric processing tube will maintain stable operation.

[0091] This process is repeated alternately to issue the next stage speed-up command for the first fabric treatment drum, and this cycle continues until both fabric treatment drums have completed their dewatering processes.

[0092] It should be noted that the specific values ​​of 'a' seconds and 'b' seconds in this example can be flexibly set according to the specifications of the fabric treatment tube, for example, 'a' can be 5 and 'b' can be 3. Alternatively, the two values ​​'a' and 'b' can be equal; no specific limitation is made here.

[0093] In this example, the method of accelerating the operation of one fabric processing drum while maintaining stable operation of the other effectively reduces the large current generated when both motors are operating simultaneously. This reduces the current flowing through the common-mode inductor and PFC inductor, allowing the fabric processing equipment in this example to use smaller-sized common-mode inductors and PFC inductors, thereby effectively reducing the controller cost of the fabric processing equipment. It should be noted that... Figure 3 In the diagram, L represents the live wire and N represents the neutral wire. (The rest of the text appears to be unrelated and possibly machine-generated gibberish.) Figure 3 The coupling relationship between the intermediate control unit and the common-mode inductor, PFC inductor and rectifier bridge is shown. That is, the neutral and live wires pass through the common-mode inductor, are rectified and then pass through the PFC inductor, and finally pass through the intermediate control unit and are connected to the first control board and the second control board respectively.

[0094] like Figures 1 to 5 As shown, in some embodiments, during the process of controlling the first fabric treatment cylinder and the second fabric treatment cylinder to alternately perform the speed-up operation phase and the stable operation phase, when one of the treatment cylinders is in the stable operation phase, the other fabric treatment cylinder is controlled to perform any speed-up operation phase, each speed-up operation phase including one or more speed-up processes.

[0095] Taking the first fabric treatment drum (the upper drum) as an example of prioritizing the execution of the dewatering command, the specific execution process of the control method is as follows:

[0096] First, the upper drum begins the dehydration stage. The eccentricity of the upper drum is detected first, and then the maximum rotation speed of the upper drum is determined based on the eccentricity. The speed is then increased in stages.

[0097] The real-time power P1 of the upper cylinder collected by the first control board is fed back to the intermediate control unit. The intermediate control unit receives a fixed value of real-time power P1 for several consecutive seconds (within a certain error range), and determines that the rotation speed of the upper cylinder has reached the stable speed of the first stage. The upper cylinder maintains this speed; otherwise, it continues to execute the acceleration command.

[0098] Secondly, when the real-time power P1 of the upper cylinder remains a fixed value for several consecutive seconds, the intermediate control unit can send an acceleration command to the lower cylinder to the second control board. The lower cylinder then begins to execute the acceleration command. During this period, the real-time power P2 of the lower cylinder collected by the second control board is fed back to the intermediate control unit. When the real-time power P2 of the lower cylinder received by the intermediate control unit for several consecutive seconds is a fixed value (within a certain error range), the lower cylinder maintains a stable operating state.

[0099] Finally, the next stage of acceleration command is given to the upper cylinder, and the cycle continues until the end of each stage.

[0100] In this example, the method of accelerating the operation of one fabric processing drum while the other operates stably effectively reduces the large current generated when both motors are working simultaneously. This reduces the current flowing through the common-mode inductor and the PFC inductor, allowing the fabric processing equipment in this example to use smaller common-mode inductors and PFC inductors, thereby effectively reducing the controller cost of the fabric processing equipment.

[0101] like Figures 1 to 5 As shown, in some embodiments, this embodiment provides a control method for a fabric processing device, which includes a first fabric processing cylinder and a second fabric processing cylinder. The control method includes the following steps:

[0102] First, multiple speed-up and multiple stable operation stages are set in the dewatering programs of both the first and second fabric treatment drums. For example, the dewatering program can be divided into three speed-up stages, corresponding to speeds of 400 rpm, 800 rpm, and 1200 rpm, respectively, followed by a stable operation stage after each speed-up stage.

[0103] When the intermediate control unit receives a dewatering command from one of the fabric processing drums to perform the dewatering process, it determines the current operating status of the other fabric processing drum. This determination is to ensure that the dewatering processes of the two drums can be coordinated, avoiding excessive current issues caused by simultaneous speed increases of both motors.

[0104] If it is determined that another fabric processing drum is performing a dehydration process, the intermediate control unit will further determine whether the fabric processing drum is in the acceleration phase or the stable operation phase.

[0105] When the processing drum currently executing the dehydration process is determined to be in the acceleration phase, the intermediate control unit instructs the subsequent fabric processing drums that received the dehydration command to wait. Specifically, the fabric processing drum needs to wait until the processing drum currently executing the dehydration process transitions from the acceleration phase to the stable operation phase before starting. This avoids both fabric processing drums being in the acceleration phase simultaneously, reducing current peaks.

[0106] During the simultaneous execution of the dewatering process by the first and second fabric processing drums, the intermediate control unit controls the two drums to alternate between a speed-up phase and a stable operation phase. For example, when the first fabric processing drum (upper drum) prioritizes the dewatering command and enters the first stage of speed-up, the intermediate control unit monitors its power changes. When the real-time power P1 of the first fabric processing drum remains at a fixed value (with a certain error range allowed, such as b%) for a certain period of time (e.g., b seconds), the intermediate control unit determines that the first fabric processing drum has reached the stable speed of the first stage, and at this time, the first fabric processing drum maintains this speed.

[0107] After the first fabric processing tube reaches a stable state, the intermediate control unit sends an acceleration command to the second fabric processing tube (lower tube) via the second control board, causing it to begin executing the acceleration command. The intermediate control unit also monitors the power changes of the second fabric processing tube. When its real-time power P2 remains at a fixed value for a certain period of time (e.g., a seconds) (allowing for a certain error range, e.g., b%), the intermediate control unit determines that the second fabric processing tube has reached a stable state.

[0108] Subsequently, the intermediate control unit will control the first fabric processing drum to increase its speed in the next stage, such as from 400 rpm to 800 rpm. Once the first fabric processing drum reaches a stable state again, the second fabric processing drum will then begin the next stage of speed increase. This alternating speed increase will continue in a cycle until both fabric processing drums have completed all speed increase stages and reached their respective maximum speeds, after which they will proceed with the subsequent dewatering process.

[0109] It should be noted that when one fabric processing drum has completed the dehydration process, but the other fabric processing drum has not yet reached its maximum speed, the intermediate control unit directly controls the fabric processing drum that has not yet completed the dehydration process to directly reach its maximum speed for dehydration treatment, so as to effectively ensure and improve the dehydration efficiency of the fabric.

[0110] like Figure 1 As shown, an exemplary embodiment of this application provides a fabric processing apparatus. The fabric processing apparatus includes a first fabric processing tube, a second fabric processing tube, and a control module. The first and second fabric processing tubes are arranged vertically, with the first fabric processing tube located on the upper side and the second fabric processing tube located on the lower side.

[0111] The control module includes an intermediate control unit, a first control board corresponding to the first fabric processing tube, and a second control board corresponding to the second fabric processing tube.

[0112] The first control board is used to acquire the operating parameters of the corresponding first fabric processing cylinder.

[0113] The second control board is used to acquire the operating parameters of the corresponding second fabric treatment cylinder.

[0114] The intermediate control unit is used to receive the operating parameters of the two control boards and provide corresponding control commands to the two control boards based on the operating parameters, so as to control the first fabric processing tube or the second fabric processing tube accordingly.

[0115] Both the first and second fabric processing drums are equipped with a dewatering program, and each dewatering program has multiple acceleration phases and multiple stable phases. The first and second fabric processing drums are configured such that, while the first and second fabric processing drums are simultaneously executing the dewatering program, they are controlled to alternately perform acceleration phases and stable phases.

[0116] Specifically, when the first fabric processing cylinder and the second fabric processing cylinder need to execute the dewatering command simultaneously, the intermediate control unit sends an acceleration command to the first control board first, so that the first fabric processing cylinder, located on the upper side, executes the dewatering command first. During the dewatering stage, the first control board first detects the eccentricity, determines the maximum rotational speed of the first fabric processing cylinder based on the eccentricity, and then increases the speed in stages.

[0117] When the first fabric processing drum (upper drum) executes the dewatering command first and enters the first stage of speed increase, the intermediate control unit monitors its power changes. When the real-time power P1 of the first fabric processing drum remains at a fixed value (with a certain error range allowed, such as b%) for a certain period of time (e.g., b seconds), the intermediate control unit determines that the first fabric processing drum has reached the stable speed of the first stage, and at this time the first fabric processing drum maintains this speed.

[0118] After the first fabric processing tube reaches a stable state, the intermediate control unit sends an acceleration command to the second fabric processing tube (lower tube) via the second control board, causing it to begin executing the acceleration command. The intermediate control unit also monitors the power changes of the second fabric processing tube. When its real-time power P2 remains at a fixed value for a certain period of time (e.g., a seconds) (allowing for a certain error range, e.g., b%), the intermediate control unit determines that the second fabric processing tube has reached a stable state.

[0119] Subsequently, the intermediate control unit will control the first fabric processing drum to increase its speed in the next stage, such as from 400 rpm to 800 rpm. Once the first fabric processing drum reaches a stable state again, the second fabric processing drum will then begin the next stage of speed increase. This alternating speed increase will continue in a cycle until both fabric processing drums have completed all speed increase stages and reached their respective maximum speeds, after which they will proceed with the subsequent dewatering process.

[0120] This control method, which alternates between the speed-up and stable operation phases, effectively avoids the problem of excessive current that may be caused by the simultaneous speed-up of the two fabric processing cylinders, improves the stability and safety of the fabric processing equipment, and also optimizes the efficiency of power use.
