Abstract
Description
Technical Field
[0001] This application relates to the field of clothing processing, and more particularly to a clothing processing device, its control method, apparatus, and storage medium. Background Technology
[0002] People in different regions have different detergent usage habits. Some prefer low-foaming detergents, while others prefer high-foaming detergents. When using high-foaming detergents in garment processing equipment, if too much is added, it can easily lead to problems with proper dehydration. For example, excessive foam can cause the space between the inner drum and the water tank to overflow, increasing the dehydration resistance of the inner drum. This prevents the motor from driving the inner drum to a higher speed, and the motor will continue to operate at high power, causing a rapid increase in motor temperature, affecting motor performance and lifespan. In addition, excessive foam also poses a risk of overflow, which may affect the performance and lifespan of the garment processing equipment. Summary of the Invention

[0009] Obtain the rotational speed, current, and power for the first set duration;
[0010] If it is determined that the rotation speed during the first set time is less than the first rotation speed threshold and the product of current and power is greater than the first product threshold, then it is determined that there is too much foam in the dehydration process.

[0013] If it is determined that the rotation speed during the second set time is less than the second rotation speed threshold and the product of current and power is greater than the second product threshold, then it is determined that there is too much foam in the dehydration process.
[0014] In some implementations, the foam detection during the dehydration process based on the rotational speed, current, power, and a preset threshold detected during the dehydration process further includes:
[0015] If it is determined that the rotational speed during the second set duration is greater than or equal to the second rotational speed threshold, and / or the product of the current and power during the second set duration is less than or equal to the second product threshold, then dehydration continues, and the rotational speed, current, and power are obtained for the third set duration.
[0016] If it is determined that the rotational speed during the third set time is less than the third rotational speed threshold and the product of current and power is greater than the third product threshold, then it is determined that there is excessive foam in the dehydration process.
[0017] In some implementations, the first product threshold is less than the second product threshold, and the second product threshold is less than the third product threshold.
[0018] In some implementations, the method further includes:

[0021] In some implementations, the method further includes:
[0022] If excessive foam is found during the dehydration process, defoaming is performed, and the dehydration process is restarted after defoaming.
[0023] Secondly, embodiments of this application provide a control device for a garment processing equipment, comprising:
[0024] The first detection module is used to respond to the start of dehydration, time the duration of dehydration operation, and detect the speed, current and power of the motor during the dehydration process;
[0025] The second detection module is used to detect foam in the dehydration process based on the rotation speed, current, power and preset thresholds detected during the dehydration process.

[0034] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.
[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0036] This application provides a control method for a clothing processing device, which can be a washing machine, a washer-dryer combo with a drying function, or a spin dryer specifically for dehydrating clothes. The clothing processing device includes a spin dryer drum for dehydrating clothes and a motor for driving the spin dryer drum to rotate. Here, the spin dryer drum can be a separate unit, or it can be a drum with a washing function, i.e., the same drum as the washing drum. In some embodiments, the motor can be driven by a frequency converter, which adjusts the speed of the drive motor by controlling the voltage and frequency of the output power supply, thereby driving the spin dryer drum to rotate.
[0037] In related technologies, excessive foam during the dehydration process can have several negative consequences. First, the dehydration speed may not reach the set point, resulting in clothes not being fully dried. Furthermore, the continuous high-power operation of the motor during dehydration can cause a rapid increase in motor temperature, affecting motor performance and lifespan. Second, if the foam overflows, for example, flowing to the bottom of the drum and seeping into electrical components, it could pose a safety hazard.
[0038] Based on this, embodiments of this application provide a method for detecting foam during the dehydration process, which can effectively prevent foam overflow and improve the reliability of dehydration control.
[0039] like Figure 1 As shown in the figure, this application provides a control method for a garment processing device, including:
[0040] Step 101: In response to the start of dehydration, the dehydration running time is timed, and the motor speed, current and power are detected during the dehydration process.
[0041] Here, the garment handling equipment can start the spin-drying process based on the washing control program or based on user-input commands. For example, for the washing control program for washing clothes, the spin-drying stage can be started automatically after rinsing; for separate spin-drying control, the spin-drying process can be started after the user inputs a start command (e.g., via buttons, touchscreen, or remote control on the garment handling equipment).
[0042] The garment processing equipment can time the dehydration process during startup or after dehydration, and monitor the motor speed, current, and power in real time. For example, the garment processing equipment can detect the motor speed, current, and power based on feedback signals from the frequency converter, or based on sensors; this application embodiment does not limit this to specific methods.
[0043] Step 102: Based on the rotation speed, current, power and preset threshold detected during the dehydration process, foam detection is performed on the dehydration process.
[0044] Here, the garment processing equipment can detect foam during the dehydration process based on the rotation speed, current, power, and preset thresholds.
[0045] It is understandable that the preset threshold can be reasonably determined based on test data before the garment processing equipment leaves the factory. For example, the threshold corresponding to different dehydration times determined based on the dehydration operation trajectory can include: the speed threshold corresponding to the rotation speed and the product threshold corresponding to the product of current and power.
[0046] The control method of this application embodiment detects foam in the dehydration process based on the rotation speed, current, power and preset threshold detected during the dehydration process. This can detect whether there is excessive foam in the dehydration process, and thus control the garment processing equipment to perform defoaming treatment when there is excessive foam, so as to ensure the reliability of dehydration and effectively prevent the impact of foam overflow on the garment processing equipment.
[0047] It should be noted that in related technologies, a single factor (such as rotational speed) is often used for foam detection. However, rotational speed is easily affected by factors such as load weight, eccentricity in the dehydration tank, and differences in the components of the machine. Using a single factor for foam detection is difficult to cover various working conditions, resulting in low detection accuracy and a high probability of misjudgment.
[0048] The control method of this application embodiment is based on the simultaneous monitoring and foam detection of three factors: rotation speed, current, and power. During normal dehydration, the current value (usually less than 1) and power value are relatively small. When there is too much foam, the current value (usually greater than 1) and power value are relatively large. After calculation and processing, the current value and power value P*I (power value * current value) will decrease under normal circumstances and increase when there is too much foam. This can more effectively distinguish between normal conditions and excessive foam conditions and improve the accuracy of judgment.
[0049] In some embodiments, foam detection during the dehydration process is performed based on the rotational speed, current, power, and a preset threshold detected during the dehydration process, including:
[0050] Obtain the rotational speed, current, and power for the first set duration;
[0051] If it is determined that the rotation speed during the first set time is less than the first rotation speed threshold and the product of current and power is greater than the first product threshold, then it is determined that there is too much foam in the dehydration process.
[0052] Understandably, during the spin-drying stage of the garment processing equipment, if there is a lot of foam in the spin-drying drum, it will result in a certain amount of detergent and water remaining in the drum. This increases the damping of the drum, causing the motor speed to be lower than the first speed threshold for the first set time. Furthermore, with the garment spinning while still wet, the motor will operate at high power continuously, and the current will increase, causing the product of current and power for the first set time to exceed the first product threshold.
[0053] In this embodiment, based on the comparison results of the rotation speed and the first rotation speed threshold for a first set time, and the comparison results of the product of current and power for a first set time and the first product threshold, when the rotation speed for the first set time is less than the first rotation speed threshold and the product of current and power is greater than the first product threshold, it is determined that there is excessive foam in the dehydration process. This can reduce the false judgment rate of excessive foam, avoid dehydration interruption caused by false judgment, and thus effectively improve the reliability of dehydration. Furthermore, it can reasonably avoid the overflow risk and / or impact on dehydration operation caused by excessive foam. In other words, the control method of this embodiment takes into account both dehydration safety and dehydration quality, and effectively avoids the problem of decreased dehydration efficiency caused by false foam judgment.
[0054] It should be noted that the first set time can be reasonably selected based on the dehydration process, and the first speed threshold and the first product threshold can be reasonably determined based on experiments, so as to serve as the basis for judging whether there is too much foam in the dehydration process.
[0055] In some embodiments, foam detection during the dehydration process is performed based on the rotational speed, current, power, and a preset threshold detected during the dehydration process, and further includes:
[0056] If it is determined that the rotation speed for the first set duration is greater than or equal to the first rotation speed threshold, and / or the product of the current and power for the first set duration is less than or equal to the first product threshold, then dehydration continues, and the rotation speed, current, and power for the second set duration are obtained;
[0057] If it is determined that the rotation speed during the second set time is less than the second rotation speed threshold and the product of current and power is greater than the second product threshold, then it is determined that there is too much foam in the dehydration process.
[0058] It is understood that if the risk of foam overflow cannot be effectively identified based on the first rotation speed threshold and the first product threshold for the first set duration, the embodiments of this application can also determine that there is too much foam in the dehydration process when the rotation speed is less than the second rotation speed threshold and the product of current and power is greater than the second product threshold for the second set duration, based on the comparison results of the rotation speed and the second rotation speed threshold for the second set duration and the comparison results of the product of current and power for the second set duration. This second foam detection can be used to remedy the situation, thereby effectively improving the reliability of dehydration and reasonably avoiding the risk of overflow caused by excessive foam.
[0059] It should be noted that the second set duration can be reasonably selected based on the dehydration process, and the second speed threshold and the second product threshold can be reasonably determined based on experiments, so as to serve as the basis for judging whether there is excessive foam in the dehydration process.
[0060] In some embodiments, foam detection during the dehydration process is performed based on the rotational speed, current, power, and a preset threshold detected during the dehydration process, and further includes:
[0061] If it is determined that the rotational speed for the second set duration is greater than or equal to the second rotational speed threshold, and / or the product of the current and power for the second set duration is less than or equal to the second product threshold, then dehydration continues, and the rotational speed, current, and power for the third set duration are obtained;
[0062] If it is determined that the rotation speed during the third set time is less than the third rotation speed threshold and the product of current and power is greater than the third product threshold, then it is determined that there is too much foam in the dehydration process.
[0063] It is understood that if the risk of foam overflow cannot be effectively identified based on the second rotation speed threshold and the second product threshold for the second set duration, the embodiments of this application can also determine that there is too much foam in the dehydration process based on the comparison results of the rotation speed and the third rotation speed threshold for the third set duration and the comparison results of the product of current and power and the third product threshold for the third set duration. When the rotation speed for the third set duration is less than the third rotation speed threshold and the product of current and power is greater than the third product threshold, remedial measures can be taken based on this third foam detection, thereby effectively improving the reliability of dehydration and reasonably avoiding the risk of overflow caused by excessive foam.
[0064] It should be noted that the third set time can be reasonably selected based on the dehydration process, and the third speed threshold and the third product threshold can be reasonably determined based on experiments, so as to serve as the basis for judging whether there is too much foam in the dehydration process.
[0065] For example, the first product threshold is less than the second product threshold, and the second product threshold is less than the third product threshold. It is understood that if there is a risk of foam overflow, the motor's power and current will rise rapidly, and the product of power and current will increase as the dehydration run time increases.
[0066] For example, the first, second, and third set durations are all taken from the low-speed phase of the dehydration operation, for example, the phase corresponding to a motor speed of 100–400 rpm. In one application example, the first set duration is 30 seconds, the second set duration is 40 seconds, and the third set duration is 50 seconds. It is understood that the set durations can be reasonably selected based on the dehydration performance of the garment processing equipment.
[0067] In some embodiments, the control method further includes:
[0068] Detect the load capacity of the clothing;
[0069] Based on the load and the mapping relationship between the load and the preset threshold, the matching preset threshold is determined.
[0070] It is understandable that the aforementioned first speed threshold, first product threshold, second speed threshold, second product threshold, third speed threshold, and third product threshold can also correspond to the amount of clothing load. The clothing processing equipment can pre-store the mapping relationship between the load and each threshold, and based on the clothing load obtained by fuzzy weighing or other methods, find the mapping relationship and determine the matching threshold. This allows for more accurate foam detection during the dehydration stage, improving the accuracy of detecting excessive foam during the dehydration process.
[0071] In some embodiments, the control method further includes:
[0072] If excessive foam is found during the dehydration process, defoaming is performed, and the dehydration process is restarted after defoaming.
[0073] For example, if the garment processing equipment determines that there is too much foam in the dehydration process, it can perform a defoaming process of repeated water intake and drainage, and restart the dehydration process after the defoaming process. After restarting the dehydration process, the dehydration control is performed based on the aforementioned control logic to ensure that there is no excessive foam during the dehydration process until the dehydration is completed, thus ensuring that there is no foam overflow caused by excessive foam during the dehydration process.
[0074] The following application example will be used to further describe this application in detail.
[0075] like Figure 2 and Figure 3As shown in this application example, it is assumed that during the dehydration process, the motor speed is speed, the motor power is P, the motor current is I, and the recorded dehydration time is t. The control method of this clothing processing equipment includes:
[0076] Step 201, dehydration starts.
[0077] Here, the garment handling equipment can start the spin-drying process based on the washing control program or based on user-input commands. For example, for the washing control program for washing clothes, the spin-drying stage can be started automatically after rinsing; for separate spin-drying control, the spin-drying process can be started and the spin-drying control program can be run after the user inputs a start command (e.g., via buttons, touch screen, or remote control on the garment handling equipment).
[0078] When the garment processing equipment runs the dehydration control program, it times the dehydration running time t and monitors the motor speed (speed), current (I), and power (P) in real time during the dehydration process.
[0079] In step 202, at t=30s, determine whether speed<300rpm and P*I>100. If yes, proceed to steps 203 and 204; otherwise, proceed to step 205.
[0080] Here, when the garment processing equipment is running for 30 seconds during the dehydration process, it acquires the current speed (speed), current (I), and power (P) to perform the first foam detection. If speed < 300 rpm and P*I > 100 W·A (watt-ampere), it is determined that there is too much foam, and steps 203 and 204 are executed; otherwise, it is determined that there is no risk of overflowing foam, and step 205 is executed.
[0081] Step 203: Determine if there is too much foam.
[0082] Step 204, defoaming treatment.
[0083] Here, the garment processing equipment can perform a defoaming process involving repeated water intake and drainage, and return to step 201 after the defoaming process to restart the dehydration process.
[0084] Step 205: Continue with normal dehydration.
[0085] In step 206, at t=40s, determine whether speed<300rpm and P*I>200. If yes, proceed to steps 203 and 204; otherwise, proceed to step 207.
[0086] Here, when the garment processing equipment is running for 40 seconds during the dehydration process, it acquires the current speed (speed), current (I), and power (P) to perform a second foam detection. If speed < 300 rpm and P*I > 200 W·A, it is determined that there is excessive foam, and steps 203 and 204 are executed; otherwise, it is determined that there is no risk of overflowing foam, and step 207 is executed.
[0087] Step 207: Continue with normal dehydration.
[0088] In step 208, at t = 50s, determine if speed < 300rpm and P*I > 250. If yes, proceed to steps 203 and 204; otherwise, proceed to step 209.
[0089] Here, when the garment processing equipment is running for t=50s during the dehydration process, the current speed (speed), current (I), and power (P) are acquired to perform a third foam detection. If speed < 300rpm and P*I > 250W·A, it is determined that there is too much foam, and steps 203 and 204 are executed; otherwise, it is determined that there is no risk of overflowing foam, and step 209 is executed.
[0090] Step 209: Continue with normal dehydration.
[0091] Step 210, dehydration complete.
[0092] Understandably, the method in this application example allows for defoaming treatment and re-dehydration if excessive foam is detected during the first foam detection, effectively preventing foam overflow. Furthermore, if there is no risk of foam overflow, remedial detection can be performed in the second or third foam detection if the first detection fails. This allows for effective measures to be taken before foam overflow occurs, ensuring that foam does not seep into electrical components and cause safety issues. In addition, this foam detection mechanism, compared to foam detection methods based solely on rotation speed, reduces the false positive rate of excessive foam, avoiding dehydration efficiency disruptions caused by false positives. This effectively improves the reliability of dehydration while reasonably avoiding the risk of overflow and / or impact on dehydration operation caused by excessive foam.
[0093] In order to implement the method of the embodiments of this application, the embodiments of this application also provide a control device for a garment processing device. The control device for the garment processing device corresponds to the control method of the garment processing device described above. The steps in the control method embodiments of the garment processing device are also fully applicable to the control device embodiments of this garment processing device.
[0094] like Figure 4As shown, the control device of the garment processing equipment includes a first detection module 401 and a second detection module 402. The first detection module 401 is used to time the dehydration process in response to the start of the dehydration process and to detect the motor speed, current, and power during the dehydration process. The second detection module 402 is used to detect foam during the dehydration process based on the detected speed, current, power, and a preset threshold.
[0095] In some embodiments, the second detection module 402 is specifically used for:
[0096] Obtain the rotational speed, current, and power for the first set duration;
[0097] If it is determined that the rotation speed during the first set time is less than the first rotation speed threshold and the product of current and power is greater than the first product threshold, then it is determined that there is too much foam in the dehydration process.
[0098] In some embodiments, the second detection module 402 is further configured to:
[0099] If it is determined that the rotation speed for the first set duration is greater than or equal to the first rotation speed threshold, and / or the product of the current and power for the first set duration is less than or equal to the first product threshold, then dehydration continues, and the rotation speed, current, and power for the second set duration are obtained;
[0100] If it is determined that the rotation speed during the second set time is less than the second rotation speed threshold and the product of current and power is greater than the second product threshold, then it is determined that there is too much foam in the dehydration process.
[0101] In some embodiments, the second detection module 402 is further configured to:
[0102] If it is determined that the rotational speed for the second set duration is greater than or equal to the second rotational speed threshold, and / or the product of the current and power for the second set duration is less than or equal to the second product threshold, then dehydration continues, and the rotational speed, current, and power for the third set duration are obtained;
[0103] If it is determined that the rotation speed during the third set time is less than the third rotation speed threshold and the product of current and power is greater than the third product threshold, then it is determined that there is too much foam in the dehydration process.
[0104] In some embodiments, the first product threshold is less than the second product threshold, and the second product threshold is less than the third product threshold.
[0105] In some embodiments, the control device of the garment processing equipment further includes:
[0106] The third detection module 403 is used to detect the load of clothing;
[0107] The threshold determination module 404 is used to determine a matching preset threshold based on the load and the mapping relationship between the load and a preset threshold.
[0108] In some implementations, the control device of the garment processing equipment further includes a control module 405 for performing defoaming treatment if it is determined that there is too much foam in the dehydration process, and restarting the dehydration process after the defoaming treatment.
[0109] In practical applications, the first detection module 401, the second detection module 402, the third detection module 403, the threshold determination module 404, and the control module 405 can be implemented by the processor in the control device of the garment processing equipment. Of course, the processor needs to run the computer program in the memory to implement its functions.
[0110] It should be noted that the control device for the garment processing equipment provided in the above embodiments is only illustrated by the division of the above-described program modules. In practical applications, the above processing can be assigned to different program modules as needed, that is, the internal structure of the device can be divided into different program modules to complete all or part of the processing described above. Furthermore, the control device for the garment processing equipment provided in the above embodiments and the control method embodiments for the garment processing equipment belong to the same concept, and their specific implementation process is detailed in the method embodiments, which will not be repeated here.
[0111] Based on the hardware implementation of the above program modules, and in order to implement the method of the embodiments of this application, the embodiments of this application also provide a clothing processing device. Figure 5 This is merely an exemplary structure of the garment processing device, not the entire structure; it can be implemented as needed. Figure 5 The structure shown may be part or all of the structure.
[0112] like Figure 5 As shown, the garment processing device 500 provided in this embodiment includes at least one processor 501, a memory 502, and a user interface 503. The various components in the garment processing device 500 are coupled together via a bus system 504. It can be understood that the bus system 504 is used to implement communication between these components. In addition to a data bus, the bus system 504 also includes a power bus, a control bus, and a status signal bus. However, for clarity, in...

[0115] The control method for the garment processing device disclosed in this application can be applied to or implemented by the processor 501. The processor 501 may be an integrated circuit chip with signal processing capabilities. During implementation, each step of the control method for the garment processing device can be completed by the integrated logic circuits in the hardware of the processor 501 or by instructions in software form.
