Description

Technical Field

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

[0002] As people's living standards improve, their demands for fabric cleanliness are also increasing. Fabric handling equipment, such as washing machines, as one of the essential household appliances, is constantly improving in terms of function and performance. There is a growing emphasis on separate washing zones and healthy washing techniques, leading most washing machines to move towards twin-drum or multi-drum designs. Currently, various twin-drum integrated washing machines have appeared on the market. These machines typically include two independent fabric handling drums, allowing for the simultaneous processing of different fabrics to improve washing efficiency.

[0003] However, existing twin-drum integrated washing machines still have some problems in actual use. First, during the washing stage, when the two fabric handling drums operate simultaneously, due to the limitations of the mechanical structure, the two drums will vibrate against each other, affecting the washing effect and increasing the noise of the equipment. Second, the simultaneous operation of the two drums during the washing process leads to higher energy consumption, reducing the user experience. Summary of the Invention

[0004] In view of this, this application provides a control method, electronic device and fabric processing equipment for fabric processing equipment, in order to solve the problem that existing fabric processing equipment is prone to resonance when multiple tubes work at the same time, resulting in obvious noise and poor user experience.

[0005] A first aspect of this application provides a control method for a fabric processing device, the fabric processing device including two fabric processing drums arranged vertically, each of the two fabric processing drums being equipped with a washing program, the control method including:

[0006] In response to an instruction that two fabric handling drums shall execute a washing program simultaneously, the fabric handling drum that shall start the washing program first shall be determined.

[0007] The start of the washing program for the other fabric treatment drum to be washed is determined based on the operating status of the fabric treatment drum that initiates the washing program first.

[0008] During the simultaneous execution of the washing program by the two fabric handling drums, the two fabric handling drums are controlled to have different operating states at the same washing time point.

[0018] When the power of the fabric treatment drum that is prioritized to start is lower than a first preset value, it is determined that another fabric treatment drum will be started simultaneously to perform the washing program.

[0019] In some embodiments, determining whether to simultaneously start another fabric treatment drum to execute a washing program based on the power information includes:

[0020] When the power of the fabric treatment drum that is prioritized to start is 0, the other fabric treatment drum is controlled to start the washing program.

[0021] In some implementations, controlling the two fabric treatment drums to have different washing states at the same washing time point includes:

[0022] The drive motors that control the two fabric processing cylinders operate alternately.

[0023] In some embodiments, the alternating operation of the drive motors controlling the two fabric processing cylinders includes:

[0024] When one fabric processing cylinder is running, the other fabric processing cylinder is controlled to be in standby mode.

[0025] When the fabric processing drum that is running in the front finishes its operation and the output power is 0, control the other fabric processing drum to start running.

[0026] When the fabric processing drum that runs later is running, control the other fabric processing drum to be in standby mode.

[0027] When the second fabric treatment drum finishes its operation and its output power is 0, the other fabric treatment drum, which is in standby mode, is started to operate. This process is repeated until both fabric treatment drums have completed their washing cycles.

[0028] In some embodiments, controlling the drive motors of the two fabric processing cylinders to operate alternately includes controlling the drive motors of the two fabric processing cylinders to operate alternately according to a preset start-stop ratio.

[0029] In some implementations, the fabric handling drum that is selected to initiate the washing program first is the upper fabric handling drum.

[0030] A second aspect of this application provides a control method for a fabric processing device, the fabric processing device including two fabric processing cylinders arranged vertically, the control method comprising:

[0031] When one of the two fabric handling drums is operating in a washing mode, in response to the start signal of the other of the two fabric handling drums, when one of the fabric handling drums is in a paused state of the first rotation-stop ratio in the washing mode, the other fabric handling drum is controlled to rotate.

[0032] In some embodiments, controlling the rotation of one of the fabric treatment cylinders includes:

[0033] When one of the two fabric handling drums is running a washing mode, in response to the start signal of the other of the two fabric handling drums, when one of them is in a paused state of a first spin-stop ratio in the washing mode, the load level of the fabric inside the other of the two fabric handling drums is determined;

[0034] The second start-stop ratio of one of the load classes is determined based on the load level, or the second start-stop ratio of the other load class is determined based on the load level and the first start-stop ratio.

[0035] The operation of the two fabric processing cylinders is controlled based on the first start-stop ratio and the second start-stop ratio.

[0036] In some embodiments, the two fabric processing tubes include an upper tube and a lower tube, the first rotation-to-stop ratio of the upper tube includes a first rotation state and a first pause state, and the second rotation-to-stop ratio of the lower tube includes a second rotation state and a second pause state.

[0037] The control of the two fabric processing cylinders based on the first turn-to-stop ratio and the second turn-to-stop ratio includes:

[0039] or,

[0040] When the lower cylinder switches from the second rotating state to the second paused state, if the upper cylinder is in the first paused state, the upper cylinder is controlled to the first rotating state and continues to operate according to the first rotation-stop ratio of the upper cylinder.

[0041] In some embodiments, the sum of the running time of the first rotating state and the running time of the second rotating state is less than or equal to the sum of the running time of the first paused state and the running time of the second paused state.

[0042] In some implementations, determining the second turnaround ratio of the other one based on the load level and the first turnaround ratio includes:

[0043] Multiple candidate start-stop ratios are determined based on the load level.

[0044] The candidate turn-stop ratio with the shortest duration of simultaneous rotation with the first turn-stop ratio is selected from the plurality of candidate turn-stop ratios and used as the second turn-stop ratio;

[0045] The control of the two fabric processing cylinders based on the first turn-to-stop ratio and the second turn-to-stop ratio includes:

[0046] While controlling one of the components to rotate according to the first rotation-to-stop ratio, the other component is controlled to rotate according to the second rotation-to-stop ratio.

[0047] If it is predicted, based on the first turn-to-stop ratio and the second turn-to-stop ratio, that one of the two will be in a turning state at the same time, then the other one is controlled to be in a paused state, and the cumulative duration of the paused state is accumulated.

[0048] After one or the other washing mode ends, the washing time of the other mode is extended based on the accumulated time.

[0049] A third aspect of the present application provides a fabric processing device that is controlled by a control method for fabric processing devices as described in the first or second aspect. The fabric processing device includes an intermediate control unit, a first control board, and a second control board.

[0050] The first control board is connected to the upper cylinder to obtain the first operating parameters of the upper cylinder, and the second control board is connected to the lower cylinder to obtain the second operating parameters of the lower cylinder.

[0051] The intermediate control unit is used to receive the first operating parameters and the second operating parameters, and send corresponding control commands to the first control board and the second control board respectively based on the first operating parameters and the second operating parameters, so as to control the upper cylinder and the lower cylinder respectively.

[0052] A fourth 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.

[0070] 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, and should not be construed as limiting this application.

[0071] like Figure 1 As shown, the fabric processing equipment 100 includes two fabric processing cylinders, namely an upper cylinder 110 and a 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.

[0072] The upper cylinder 110 is driven to rotate by the first motor 111, and the lower cylinder 120 is driven to rotate by the second motor 121.

[0073] In practical use, the first control board 112 is connected to the upper cylinder 110 to obtain the first operating parameters of the upper cylinder 110. The second control board 122 is connected to the lower cylinder 120 to obtain the second operating parameters of the lower cylinder 120. The intermediate control unit 130 is used to receive the first and second operating parameters, and send corresponding control commands to the first control board 112 and the second control board 122 respectively based on the first and second operating parameters, so as to perform better and more precise control on the upper cylinder 110 and the lower cylinder 120 respectively.

[0074] Example 1

[0075] like Figures 1 to 4As shown, an exemplary embodiment of this application provides a control method for a fabric processing device.

[0076] The control method of this fabric treatment equipment can be applied to fabric treatment equipment. The fabric treatment equipment includes fabric treatment drums, which are used to wash fabrics. Specifically, they are used to wash the fabrics in their respective drums in a washing mode. The washing mode refers to the process of injecting a certain amount of water and detergent into the fabric treatment drum and cleaning the fabric by rotating the drum.

[0077] 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.

[0078] 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 at their uppermost positions, i.e., one fabric handling drum is located on the upper side and the other 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 a washing mode, wherein the fabric handling drum located on the upper side is the upper drum, and the fabric handling drum located on the lower side is the lower drum.

[0079] Specifically, the control method for the fabric processing equipment includes the following steps:

[0080] Step S100: In response to the instruction that the two fabric treatment drums shall execute the washing program simultaneously, determine the fabric treatment drum that shall start the washing program first.

[0081] Step S200: Determine the start of the washing program for the other fabric treatment drum to be washed based on the operating status of the fabric treatment drum that will start the washing program first.

[0082] Step S300: During the simultaneous execution of the washing program by the two fabric treatment drums, control the two fabric treatment drums to have different operating states at the same washing time point.

[0083] In step S100, after the control system of the fabric processing equipment receives an instruction that the two fabric processing drums need to execute the washing program simultaneously, the control system determines which fabric processing drum should execute the washing program first.

[0084] The control system can be configured based on the processing priority of the two fabric handling drums. For example, if the upper drum has a higher priority than the lower drum, the control system will prioritize the operation of the upper drum. In other words, if the lower drum is running when the upper drum needs to start, it will immediately stop running to allow the upper drum to begin. This control strategy ensures that the washing effect of the upper drum is not affected by the operating status of the lower drum.

[0085] The above control method can achieve coordinated operation of the two fabric treatment drums in the washing mode, avoiding vibration and noise problems caused by simultaneous operation, while also reducing power consumption and improving user experience.

[0086] Alternatively, when the washing program in the lower drum has a higher priority than that in the upper drum, the control system prioritizes the operation of the lower drum. In other words, if the upper drum is running when the lower drum needs to start, it will immediately stop running to allow the lower drum to begin. This control strategy ensures that the washing performance of the lower drum is not affected by its operating status.

[0087] The above control method can achieve coordinated operation of the two fabric treatment drums in the washing mode, avoiding vibration and noise problems caused by simultaneous operation, while also reducing power consumption and improving user experience.

[0088] In step S200, different operating states include the alternating operation of the drive motors of the two fabric processing cylinders. For example, one of the drive motors of the two fabric processing cylinders is rotating, while the other drive motor is in a paused rotation process.

[0089] Alternatively, different operating states may include two drive motors for the fabric processing cylinders operating simultaneously but in different directions, such as one drive motor rotating forward and the other rotating in reverse.

[0090] Alternatively, different operating states may involve two fabric processing cylinders having drive motors that rotate in the same direction but at different speeds.

[0091] This means that when the two fabric processing drums are rotating simultaneously, their rotational speeds differ. For example, in a washing cycle, the two fabric processing drums can operate at different speeds depending on the fabric material.

[0092] Based on the usage of the fabric processing equipment, the washing speed of the fabric processing drum can be divided into multiple operating levels, with higher operating levels resulting in higher drum speeds. For example, there could be three or more operating levels. A situation where the first and second rotation states are the same but their operating levels differ can occur if the difference in operating levels between the two fabric processing drums is greater than or equal to 2.

[0093] For example, when the fabric in the first fabric processing drum is made of cotton, a higher rotation speed is required, such as setting the operating level to the fourth level. However, when the fabric in the second fabric processing drum is made of silk, a lower rotation speed is required than that of the first fabric processing drum. In this case, the operating level of the second fabric processing drum can be set to the second level or the first level.

[0094] In a specific example, when the first rotational state and the second rotational state are the same, the rotational speed of the other is 20% to 40% of the rotational speed of one of them. That is, the rotational speed of the first fabric processing drum can be 20% to 40% of the rotational speed of the second fabric processing drum, or the rotational speed of the second fabric processing drum is 20% to 40% of the rotational speed of the first fabric processing drum.

[0095] Preferably, when the first rotation state and the second rotation state are the same, the rotational speed of the other one is 30% of the rotational speed of the first one.

[0096] In addition, when the fabric material inside the two fabric processing cylinders is the same, the difference in the operating level between the two fabric processing cylinders can be set to be greater than or equal to 2. In this way, the speed difference between the two fabric processing cylinders can be limited, thereby reducing the noise of the two fabric processing cylinders running at the same time within a predetermined range.

[0097] or,

[0098] When the first and second rotation states are the same, the rotation speed of one of the fabric treatment cylinders is controlled to be 20% to 40% of that of the first, but the rotation direction of the first cylinder is opposite to that of the second. That is, the rotation speed of the first fabric treatment cylinder can be 20% to 40% of the rotation speed of the second, or the rotation speed of the second is 20% to 40% of the rotation speed of the first. However, when the two fabric treatment cylinders rotate simultaneously, they operate in different rotation directions to balance the vibrations of the two cylinders in their respective rotation directions, thereby reducing the noise when the two fabric treatment cylinders rotate simultaneously within a predetermined range.

[0099] Preferably, when the first rotation state and the second rotation state are the same, the rotational speed of the other one is 30% of the rotational speed of the first one.

[0100] Based on the above description of different operating states, the following method can be used in the step of determining the start of the washing program for the other fabric treatment drum to be washed, according to the operating state of the fabric treatment drum that prioritizes the washing program:

[0101] First, during the washing program executed by the fabric treatment drum that is prioritized, the operation information of the fabric treatment drum that is prioritized is acquired in real time.

[0102] Secondly, based on the operating information of the fabric treatment drum that takes priority, it is determined whether to simultaneously start another fabric treatment drum to perform a washing program. If determined, the other fabric treatment drum is started to perform a washing program.

[0103] In this process, the power information of the drive motor of the fabric treatment drum that is prioritized to start is first acquired in real time. Then, based on the power information, it is determined whether to simultaneously start the washing program of another fabric treatment drum. Specifically, when the power of the fabric treatment drum that is prioritized to start is lower than a first preset value, it is determined that the other fabric treatment drum will be started simultaneously. Specifically, when the power of the fabric treatment drum that is prioritized to start is 0, the other fabric treatment drum is controlled to start the washing program.

[0104] In step S300, the process of controlling the two fabric processing drums to have different washing states at the same washing time node includes: controlling the drive motors of the two fabric processing drums to operate alternately.

[0105] Specifically, in one example, while one fabric processing cylinder is operating, the other fabric processing cylinder is controlled to be in a standby state. When the previously operating fabric processing cylinder finishes its operating phase and its output power is 0, the other fabric processing cylinder is controlled to start operating.

[0106] While the second fabric treatment drum is running, the other fabric treatment drum is put into standby mode. When the second fabric treatment drum finishes its operation and its output power is 0, the other fabric treatment drum in standby mode is started to run. This cycle continues until both fabric treatment drums have completed their washing programs.

[0107] In some embodiments, controlling the drive motors of the two fabric processing cylinders to operate alternately includes controlling the drive motors of the two fabric processing cylinders to operate alternately according to a preset start-stop ratio.

[0108] The rotation-to-stop ratio control includes both the rotation and pause processes of the drive motors. For example, one drive motor may be in the rotation process within the rotation-to-stop ratio, while the other drive motor may be in the paused rotation process. The paused rotation process includes at least the period during which the drive motor of the fabric handling cylinder pauses operation during the rotation-to-stop ratio control process.

[0109] Rotation-stop ratio control refers to a control method in which the drive motor alternates between rotation and stopping at certain time intervals during the washing process. For example, the motor rotates for 10 seconds, then stops for 5 seconds, and this cycle repeats. This control method can effectively clean fabrics while reducing fabric tangling and wear.

[0110] Additionally, the rotation-to-stop ratio refers to the ratio of the inner drum's rotation time to its stopping time. For example, the rotation-to-stop ratio for the upper drum can be set to rotate for 30 seconds, stop for 20 seconds, then rotate for another 30 seconds, and so on. The rotation-to-stop ratio for the lower drum can be set to rotate for 25 seconds, stop for 25 seconds, then rotate for another 25 seconds, and so on.

[0111] In other words, in actual use, by controlling the rotation and stop ratios of the two fabric processing cylinders separately and in a cross-cutting manner, the vibration and noise problems caused by the simultaneous operation of the two fabric processing cylinders can be avoided, thus improving the user experience.

[0112] Specifically, the two fabric processing tubes include an upper tube and a lower tube. The upper tube operates periodically on and off according to a first rotation-to-stop ratio, and the periodic operation includes a first rotation state and a first pause state. The lower tube operates periodically on and off according to a second rotation-to-stop ratio, and the periodic operation includes a second rotation state and a second pause state.

[0113] In this example, by utilizing the rotation-stop ratio of the fabric treatment drums, the operation of the two fabric treatment drums can be controlled separately, reducing the resonance and noise generated by the two fabric treatment drums working together, effectively shortening the overall washing time, and improving the user experience.

[0114] like Figures 1 to 4 As shown, in some embodiments, the fabric processing equipment includes an intermediate control unit; and two fabric processing tubes, each corresponding to a control board with a data connection, the control board being used to acquire the operating parameters of the corresponding fabric processing tube. The intermediate control unit is used to receive the operating parameters from the two control boards and, based on the operating parameters, send corresponding control commands to the two control boards to perform corresponding control on the two fabric processing tubes.

[0115] In this embodiment, the fabric processing equipment includes two fabric processing drums arranged vertically, namely an upper drum and a lower drum. Each fabric processing drum has an inner drum for containing fabric, which is driven to rotate by a motor to wash the fabric. The upper drum and the lower drum are controlled by a first control board and a second control board, respectively, and both control boards are data connected to an intermediate control unit.

[0116] When the user starts the fabric handling equipment and selects a washing mode, the intermediate control unit sends a washing command to the first and second control boards, causing the upper and lower drums to start synchronously and enter the washing mode. In the washing mode, the inner drums of the upper and lower drums need to rotate and stop at a specific rotation-to-stop ratio to achieve a good washing effect.

[0117] The rotation-to-stop ratio refers to the proportional relationship between the rotation time and the stopping time of the inner drum. For example, the rotation-to-stop ratio of the upper drum can be set to rotate for 30 seconds, stop for 20 seconds, then rotate for another 30 seconds, and so on. The rotation-to-stop ratio of the lower drum can be set to rotate for 25 seconds, stop for 25 seconds, then rotate for another 25 seconds, and so on.

[0118] When both fabric handling drums are started synchronously and in washing mode simultaneously, the intermediate control unit obtains the operating status of the upper drum through the first control board. When the upper drum is detected to be in a paused state (i.e., the upper drum motor has stopped running), the intermediate control unit sends a control command to the second control board, causing the inner drum of the lower drum to start rotating. Thus, when the upper drum is in a paused state, the lower drum is in a running state; and when the lower drum is in a paused state, the upper drum is in a running state.

[0119] This control method avoids vibration and noise problems caused by the simultaneous operation of two fabric processing cylinders, while also reducing power consumption. Furthermore, because the two fabric processing cylinders operate alternately, power resources can be utilized more efficiently, avoiding excessive power peaks.

[0120] In a specific example, the first control board can determine whether the motor of the first fabric processing drum is in a suspended state by sampling the three-phase voltage of the upper drum motor through a sampling resistor, calculating the motor power P1, and feeding the power data back to the intermediate control unit. When P1 equals 0, it indicates that the upper drum motor is in a suspended state (i.e., stopped). At this time, the intermediate control unit sends a control command to the second control board to start the lower drum motor. Similarly, the second control board also samples the three-phase voltage of the lower drum motor through a sampling resistor, calculates the motor power P2, and feeds the power data back to the intermediate control unit. When P2 equals 0, it indicates that the lower drum motor is in a suspended state. At this time, the intermediate control unit sends a control command to the first control board to start the upper drum motor.

[0121] Example 2

[0122] like Figures 1 to 4 As shown, an exemplary embodiment of this application provides another control method for a fabric processing device, which can be applied to a fabric processing device. The fabric processing device includes a fabric processing drum, which is capable of washing fabrics, that is, washing the fabrics in its respective drum in a washing mode. The washing mode refers to the process of injecting a certain amount of water and detergent into the fabric processing drum and cleaning the fabrics by rotating the fabric processing drum.

[0123] 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.

[0124] 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 at their upper limits, i.e., one fabric handling drum is located on the upper side and the other 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 a washing mode, wherein the fabric handling drum located on the upper side is called the upper drum, and the fabric handling drum located on the lower side is called the lower drum.

[0125] Specifically, the control method for the fabric processing equipment includes the following steps:

[0126] Step S10: When one of the two fabric handling drums is running a washing mode, in response to the start signal of the other fabric handling drum, when one of the fabric handling drums is in the paused state of the first rotation-stop ratio in the washing mode, control the other fabric handling drum to rotate.

[0127] In step S10, when one of the fabric handling drums has started running, i.e. is in the washing mode, and the other fabric handling drum needs to execute the washing command and is about to start the washing mode, when one of the fabric handling drums is in the paused state of the first rotation-stop ratio in the washing mode, the other fabric handling drum is controlled to rotate.

[0128] For example, when the upper drum has started washing the fabric, and the upper drum is in the paused state at the first rotation-stop ratio, the fabric in the lower drum can be weighed first to determine the load level of the fabric in the lower drum, and then the lower drum can be logically controlled according to the load level of the fabric.

[0129] Specifically, the process of controlling the rotation of one of the fabric processing cylinders includes:

[0130] First, determine the load level of the fabric in the other fabric treatment drum.

[0131] Then, a second turn-stop ratio for the corresponding fabric treatment cylinder is determined based on the load level, or a second turn-stop ratio for the other is determined based on the load level and the first turn-stop ratio.

[0132] Finally, the operation of the two fabric processing cylinders is controlled based on the first and second rotation-stop ratios.

[0133] Each load level has a corresponding turn-to-stop ratio. Therefore, after determining the load level of the fabric in step S10, the second turn-to-stop ratio of the fabric in the fabric treatment drum corresponding to the load level can be determined.

[0134] Alternatively, the second start-stop ratio of one of them can be determined based on the load level and the first start-stop ratio.

[0135] Taking the operation of the first fabric treatment drum as an example, after determining the load level of the second fabric treatment drum, the second rotation-to-stop ratio of the second fabric treatment drum is determined based on the first rotation-to-stop ratio of the first fabric treatment drum and the load level of the second fabric treatment drum, and vice versa.

[0136] The determination of the second rotation stop ratio for the specific second fabric processing drum can be achieved using the following method: Multiple candidate rotation stop ratios are determined based on the load level. From these candidate ratios, the candidate rotation stop ratio with the shortest simultaneous rotation time with the first rotation stop ratio is selected as the second rotation stop ratio.

[0137] Then, based on the first and second rotation-to-stop ratios, during the operation of the two fabric handling drums, while controlling one to rotate according to the first rotation-to-stop ratio, the other is controlled to rotate according to the second rotation-to-stop ratio. If it is predicted, based on the first and second rotation-to-stop ratios, that one and the other will be rotating simultaneously, then the other is controlled to be paused, and the cumulative duration of this pause is accumulated. After the washing mode of one or the other ends, the washing time of the other is extended based on the accumulated duration.

[0138] Based on this, after completing the washing process of two fabric treatment drums within the effective time, the cumulative time usage strategy can guarantee the washing time and quality of the subsequent fabric treatment drum, thereby improving the washing effect on the fabrics and enhancing the user experience.

[0139] The two fabric processing tubes are labeled as an upper tube and a lower tube. The first rotation-stop ratio of the upper tube includes a first rotation state and a first pause state, and the second rotation-stop ratio of the lower tube includes a second rotation state and a second pause state.

[0140] Based on this, in this step, if the lower cylinder is in the second pause state when the upper cylinder switches from the first rotating state to the first pause state, the lower cylinder will be controlled to the second rotating state and will continue to operate according to the second rotation-stop ratio of the lower cylinder.

[0141] Alternatively, if the upper cylinder is in the first pause state while the lower cylinder is in the second rotating state, the upper cylinder will be controlled to the first rotating state and will continue to operate according to the first rotation-to-stop ratio of the upper cylinder.

[0142] Specifically, when the upper cylinder rotates in the first rotation state, the lower cylinder is controlled to stop operating in the second pause state, wherein the first rotation state is less than or equal to the second pause state.

[0143] In addition, when the upper cylinder stops running in the first pause state, the lower cylinder is controlled to rotate in the second rotation state, wherein the second rotation state is greater than or equal to the first pause state.

[0144] In this example, by utilizing the rotation-stop ratio of the fabric treatment drums to separately control the operation of the two fabric treatment drums, the resonance and noise generated by the two fabric treatment drums working together are reduced, effectively shortening the overall washing time and improving the user experience.

[0145] like Figures 1 to 4 As shown, in some embodiments, the fabric processing equipment includes an intermediate control unit, a first control board, and a second control board. The first control board is connected to the upper bobbin to obtain first operating parameters of the upper bobbin, and the second control board is connected to the lower bobbin to obtain second operating parameters of the lower bobbin. The intermediate control unit is used to receive the first and second operating parameters, and send corresponding control commands to the first and second control boards respectively based on the first and second operating parameters to control the upper and lower bobbins separately.

[0146] The upper cylinder 110 is driven and rotated by a first motor 111, and the lower cylinder 120 is driven and rotated 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 connected to the intermediate control unit 130 for data transfer.

[0147] In practical use, the first control board 112 is connected to the upper cylinder 110 to obtain the first operating parameters of the upper cylinder 110. The second control board 122 is connected to the lower cylinder 120 to obtain the second operating parameters of the lower cylinder 120. The intermediate control unit 130 is used to receive the first and second operating parameters, and send corresponding control commands to the first control board 112 and the second control board 122 respectively based on the first and second operating parameters, so as to perform better and more precise control on the upper cylinder 110 and the lower cylinder 120 respectively.

[0148] When the user starts the fabric handling equipment and selects a washing mode, the intermediate control unit sends a washing command to the first and second control boards. First, the two fabric handling drums perform a weighing operation to determine the load level of the internal fabric. The fabric load level is divided into five levels: very light load (less than 1 kg), light load (1-3 kg), medium load (3-6 kg), heavy load (6-8 kg), and full load (10 kg).

[0149] Depending on the fabric load level, the control system of the fabric handling equipment sets a corresponding rotation-stop ratio for each fabric handling drum. For example, for the upper drum, if the load level is medium, the first rotation-stop ratio may be set to rotate for 30 seconds and stop for 20 seconds; for the lower drum, if the load level is low, the second rotation-stop ratio may be set to rotate for 25 seconds and stop for 25 seconds.

[0150] During the washing process, the intermediate control unit coordinates the operation of the two fabric handling drums according to the first rotation-to-stop ratio and the second rotation-to-stop ratio. Specifically, when the upper drum rotates in the first rotation state, the lower drum stops operating in the second pause state; when the upper drum stops operating in the first pause state, the lower drum rotates in the second rotation state.

[0151] In one example, to minimize noise during the washing process, the two fabric handling drums are configured not to rotate simultaneously. To ensure this, the fabric handling equipment's control system ensures that the operating time of the first rotating state is less than or equal to the operating time of the second paused state, and that the operating time of the second rotating state is greater than or equal to the operating time of the first paused state. Furthermore, the control system also ensures that the sum of the operating times of the first and second rotating states is less than or equal to the sum of the operating times of the first and second paused states.

[0152] For example, if the first rotation-to-stop ratio of the upper bobbin is 30 seconds of rotation followed by 20 seconds of stop, and the second rotation-to-stop ratio of the lower bobbin is 25 seconds of rotation followed by 25 seconds of stop, then the control system of the fabric handling equipment will ensure that the lower bobbin is stopped when the upper bobbin rotates for 30 seconds; when the upper bobbin stops for 20 seconds, the lower bobbin can rotate for 20 seconds (because the running time of the second rotation state is greater than or equal to the running time of the first stop state). Furthermore, the sum of the running time of the first rotation state (30 seconds) and the running time of the second rotation state (25 seconds) is 55 seconds, and the sum of the running time of the first stop state (20 seconds) and the running time of the second stop state (25 seconds) is 45 seconds, which does not satisfy the sum condition.

[0153] Therefore, the control system of the fabric handling equipment adjusts the rotation-stop ratio. For example, the first rotation-stop ratio of the upper drum is adjusted to 20 seconds of rotation followed by 25 seconds of stop, and the second rotation-stop ratio of the lower drum is adjusted to 20 seconds of rotation followed by 25 seconds of stop. In this way, the sum of the running time of the first rotation state (20 seconds) and the running time of the second rotation state (20 seconds) is 40 seconds, and the sum of the running time of the first stop state (25 seconds) and the running time of the second stop state (25 seconds) is 50 seconds, satisfying the sum condition.

[0154] This control method allows for dynamic adjustment of the rotation-stop ratio based on the fabric load level, enabling the two fabric handling drums to operate alternately during the washing process. This avoids vibration and noise issues caused by simultaneous operation and optimizes the washing effect based on the fabric load level, thereby improving the user experience.

[0155] In this example, when one fabric handling drum has started running, if another fabric handling drum needs to execute a washing command, the control system of the fabric handling equipment will pause the running fabric handling drum and allow the other fabric handling drum to perform a weighing operation to determine the fabric load level. After weighing, the control system of the fabric handling equipment will set the appropriate start-stop ratio according to the fabric load level and then coordinate the operation of the two fabric handling drums.
