[0029] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0030] Numerous specific details are set forth in the following description in order to provide a full understanding of this application. The described embodiments are only some, not all, of the embodiments of this application.

[0031] 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.

[0032] The garment handling equipment can be a dryer, a washer-dryer combo, or other equipment with garment drying functions, and there are no restrictions on this. This application only uses a dryer as an example of garment handling equipment. During the drying process, clothes often become tangled, affecting the drying effect. Therefore, during the drying process, it is necessary to detect whether there is a tangling problem in order to perform a series of untangling operations, such as adjusting the tumbling rhythm.

[0033] In related technologies, the presence of tangled clothes is determined by monitoring the current of the drum drive motor or the drum speed. Taking the drum drive motor current as an example, during the drying process, tangling clothes can cause drum imbalance and increased drum torque. In this case, increasing the drum drive motor current increases the drum torque to stabilize the drum speed. Therefore, when a sudden and sustained increase in the drum drive motor current is detected, it can be determined that clothes are tangled. However, in practical applications, the magnitude of the drum drive motor current is also related to the resistance experienced by the drum rotation. During the assembly of the clothes dryer, the fit between the drum and the sealing foam and / or belt cannot be perfectly consistent, resulting in inconsistent resistance experienced by the drum. Therefore, during actual software debugging, to avoid the problem of inconsistent resistance experienced by the drum during dryer assembly, the preset current threshold of the drum drive motor is set relatively high. However, setting a relatively high preset current threshold has drawbacks such as poor sensitivity in detecting tangled clothes. For example, it may not detect tangling when clothes are only slightly tangled, or it may not detect tangling when there are few clothes in the dryer. Therefore, the accuracy of the above-mentioned clothing entanglement monitoring is low, and the drying effect of the dryer cannot be guaranteed.

[0034] To address the aforementioned issues, this application provides a method for controlling a garment processing device to improve the drying effect of garments.

[0035] Combination Figure 1 This application provides an illustration of the equipment diagram for controlling the garment processing equipment according to an embodiment. (See diagram for example.) Figure 1 As shown, the garment handling device 30 includes a memory 31, at least one controller 32, at least one communication bus 33, a roller 34, and a roller drive motor 35. The roller 34 is used to hold garments, and the roller drive motor 35 is used to drive the roller 34 to rotate. The controller 32 executes the calculation program stored in the memory 31 to implement a control method for the garment handling device.

[0037] In one embodiment of this application, the clothing handling device 30 may be an electronic device with clothing drying function, including a dryer and a washer-dryer combo. Although not shown, the clothing handling device 30 may also be connected to a client device, which includes, but is not limited to, any electronic product that can interact with the customer via a keyboard, mouse, remote control, touchpad, or voice control device, such as a personal computer, tablet computer, smartphone, digital camera, etc.

[0041] Figure 2 This is a schematic flowchart of a clothing processing equipment control method provided in an embodiment of this application. The clothing processing equipment control method can be applied to clothing processing equipment. Figure 2 As shown, the control method for garment processing equipment may include the following steps. Depending on different needs, the order of the steps in this flowchart may be changed, and some may be omitted.

[0042] S11, Obtain the operating parameters of the garment processing equipment.

[0043] In some embodiments, operating parameters refer to parameters related to clothing entanglement during the operation of the garment processing equipment. For example, operating parameters may include one or more of the roller speed and the roller drive motor current. The roller speed can be detected and obtained by installing a speed sensor within the garment processing equipment, and the roller drive motor current can be detected and obtained by installing a current sensor within the garment processing equipment.

[0044] S12, when the operating parameters meet the first working state, control the drum drive motor to perform an untangling operation on the clothes in the drum at the first rotation rhythm.

[0045] In some embodiments, the first working state may represent the working state when the degree of entanglement of the clothes in the drum is heavy entanglement, wherein the degree of entanglement includes heavy, light and no entanglement.

[0046] The first rotation cycle can be the rotation parameters used by the roller to perform an untangling operation when heavily tangled clothing is detected. This first rotation cycle differs from the rotation cycle during normal roller operation. Taking the normal rotation direction of the roller as positive (e.g., clockwise) as an example, the rotation direction of the first rotation cycle is a forward-reverse cycle (e.g., clockwise-counterclockwise cycle). When the operating parameters meet the first working state, it is determined that the clothing inside the roller is heavily tangled. The roller drive motor needs to be controlled to perform a forward-reverse cycle rotation of the clothing inside the roller using the first rotation cycle to achieve the untangling operation.

[0047] In other embodiments, the rotation direction of the drum during normal operation can be a forward-reverse cyclic rotation, and the rotation direction of the first rotation cycle can also be a forward-reverse cyclic rotation, but the forward-reverse switching frequency of the first rotation cycle is greater than the forward-reverse switching frequency when the drum is operating normally.

[0048] S13, when the operating parameters meet the second working state, a dewinding command is randomly triggered, and according to the triggered dewinding command, the roller drive motor is controlled to perform a dewinding operation on the clothes at the second rotation beat.

[0049] In some embodiments, the second working state can be the working state when the clothes in the drum are slightly tangled or not tangled. The second rotation rhythm can be the rotation parameters on which the drum performs the untangling operation when the slight tangling or non-tangling of the clothes is detected. The second rotation rhythm is different from the rotation rhythm when the drum is working normally. Taking the rotation direction of the drum during normal operation as positive as an example, the rotation direction of the second rotation rhythm is a forward-reverse cycle. When the operating parameters meet the second working state, it is determined that the clothes in the drum are slightly tangled or not tangled, and an untangling command is randomly triggered. According to the triggered untangling command, the drum drive motor is controlled to perform forward-reverse cycle rotation on the clothes in the drum at the second rotation rhythm to realize the untangling operation of the clothes.

[0050] In other embodiments, the rotation direction of the drum during normal operation can be a forward-reverse cyclic rotation, and the rotation direction of the second rotation cycle can also be a forward-reverse cyclic rotation, but the forward-reverse switching frequency of the second rotation cycle is greater than the forward-reverse switching frequency when the drum is operating normally.

[0051] In some embodiments, the unwinding command refers to the command used to control the drum drive motor to perform an unwinding operation on the clothes at a second rotational pace. The process of randomly triggering the unwinding command can be stored in the memory of the clothes handling device in the form of code. For example, during a single drying process, multiple unwinding commands may be triggered, or no unwinding command may be triggered; the number and frequency of triggering are not limited here. In this embodiment, when it is determined that the clothes in the drum are slightly tangled or not tangled, the unwinding operation is performed by randomly triggering the unwinding command. Compared with directly controlling the drum drive motor to perform the unwinding operation on the clothes at a second rotational pace, this reduces the burden on the drum drive motor, saving energy and reducing wear and tear on the drum drive motor.

[0052] In some embodiments, after a random untangling command is triggered, the method may further time a preset duration (also referred to as a fifth preset duration in this application embodiment); if no untangling command is triggered within the preset duration, the method returns to the step of obtaining the operating parameters of the garment processing equipment and restarts the timing. The preset duration is pre-set, for example, 5 minutes.

[0053] In the above-mentioned control method for clothing processing equipment provided in this application embodiment, the working state of the clothing processing equipment is determined by obtaining the operating parameters of the clothing processing equipment, thereby distinguishing the unwinding method under different working states, which can improve the unwinding effect and thus ensure the drying effect of clothing under different states; and when the clothing processing equipment is in the second working state, this application adds a random unwinding triggering mechanism so that unwinding can be achieved through probability events even when the clothing is slightly tangled, there are few clothes, or a fault is detected, thereby ensuring the drying effect of clothing.

[0054] Figure 3 This is another flowchart of the garment processing equipment control method provided in this application embodiment. The garment processing equipment control method can be applied to garment processing equipment. Figure 3 As shown, the control method for garment handling equipment may include the following steps:

[0055] S31, Obtain the operating parameters of the garment processing equipment.

[0056] The specific implementation method of step S31 is the same as that of step S11 above, and will not be repeated here.

[0057] S32, when the operating parameters meet the first working state, control the drum drive motor to perform an unwinding operation on the clothes in the drum at the first rotation rhythm.

[0058] The specific implementation method of step S32 is the same as that of step S12 above, and will not be repeated here.

[0059] S33, when the operating parameters meet the second working state, control the drum drive motor to perform an unwinding operation on the clothes in the drum at the second rotation rhythm.

[0060] In some embodiments, when the operating parameters meet the second working state, it is determined that the clothes in the drum are slightly tangled or not tangled. At this time, the drum drive motor is controlled to perform an untangling operation on the clothes in the drum at a second rotation rhythm to ensure the clothes drying effect of the clothes processing equipment in the second working state.

[0061] Figure 4 This is a flowchart illustrating the acquisition of operating parameters provided in an embodiment of this application. This process for acquiring operating parameters can be applied to garment processing equipment. For example... Figure 4 As shown, the following steps are included before obtaining the operating parameters of the garment processing equipment:

[0062] S41, determine the weight or quantity of clothes in the drum.

[0063] In some embodiments, when the clothes in the drum meet the entanglement conditions, the operating parameters of the clothing processing equipment are acquired, and the working state of the clothing processing equipment is determined based on the operating parameters, thereby determining whether an unwinding operation needs to be performed. When the clothes in the drum do not meet the entanglement conditions, the clothes in the drum will not entangle, therefore, it is not necessary to acquire the operating parameters of the clothing processing equipment to determine whether an unwinding operation needs to be performed. The entanglement conditions refer to pre-set conditions used to assess whether the clothes in the drum may have an entanglement problem. In one embodiment, the entanglement conditions are related to the weight or quantity of the clothes in the drum; in other embodiments, the entanglement conditions are also related to the type of clothes in the drum, including shirts, long skirts, trousers, etc. When the type of clothes is a long skirt or trousers, the probability of the clothes in the drum entanglement is higher.

[0064] In one embodiment, the weight of the clothes inside the drum can be obtained by a weighing sensor installed inside the drum. In another embodiment, the weight of the clothes inside the drum can be obtained by controlling the rotation of the drum drive motor and inputting relevant parameters during the rotation process (e.g., the power and speed of the drum drive motor) into a preset clothing weight calculation model. The input data of the preset clothing weight calculation model are parameters such as the power and speed of the drum drive motor, and the output data is the weight of the clothes inside the drum. In other embodiments, the weight of the clothes inside the drum can also be determined by monitoring the current of the drum drive motor. For example, there is a correspondence between the current and the weight of the clothes. By querying this correspondence, the weight of the clothes inside the drum corresponding to a certain current can be obtained.

[0065] In one embodiment, the quantity and type of clothing inside the drum can be determined by acquiring images of the clothing inside the drum using an image acquisition device installed inside the drum. Then, a processor determines the quantity and type of clothing based on these images. A pre-trained model for determining the quantity and type of clothing is stored in the memory. The input data for this model is the clothing image, and the output data is the quantity and type of clothing. The processor calls the clothing quantity determination model to process the clothing image to obtain the quantity and type of clothing inside the drum. The image acquisition device can be a camera or similar device.

[0066] S42, when the weight of the clothing is greater than or equal to a preset weight threshold or when the quantity of clothing is greater than or equal to a preset quantity threshold, obtain the operating parameters of the clothing processing equipment.

[0067] In some embodiments, both the preset weight threshold and the preset quantity threshold refer to pre-set values ​​indicating the likelihood of clothing tangling in the drum. When the weight of the clothing is greater than or equal to the preset weight threshold, or when the quantity of clothing is greater than or equal to the preset quantity threshold, and it is determined that the clothing in the drum meets the tangling condition, the operating parameters of the clothing processing equipment are acquired, and the working state of the clothing processing equipment is determined based on the operating parameters, thereby determining whether an untangling operation needs to be performed. When the weight of the clothing is less than the preset weight threshold, or when the quantity of clothing is less than the preset quantity threshold, and the clothing in the drum does not meet the tangling condition, the clothing in the drum will not tangle. Therefore, it is not necessary to acquire the operating parameters of the clothing processing equipment to determine whether an untangling operation needs to be performed.

[0068] In other embodiments, when the clothing type is a long skirt or trousers, the probability of the clothing in the drum getting tangled is relatively high. It is determined that the clothing in the drum meets the tangling conditions, and the operating parameters of the clothing processing equipment are obtained. When the clothing type is a shirt, it is determined that the clothing in the drum does not meet the tangling conditions, and it is not necessary to obtain the operating parameters of the clothing processing equipment.

[0069] This application embodiment determines the weight or quantity of clothing in the drum, and based on this, determines whether the clothing in the drum meets the winding conditions. If the winding conditions are met, the operating parameters of the clothing processing equipment are acquired for subsequent unwinding operations; if the winding conditions are not met, it is not necessary to acquire the operating parameters of the clothing processing equipment. This method avoids resource waste caused by ineffective monitoring of the operating parameters of the clothing processing equipment, saves energy, and improves the accuracy of the unwinding operation.

[0070] Figure 5 This is a flowchart of the working status detection provided in an embodiment of this application. The working status detection process can be applied to clothing processing equipment. Figure 5 As shown, it includes the following steps:

[0071] S51, when the drum speed is less than or equal to the preset speed threshold, or the drum drive motor current is greater than or equal to the preset current threshold and continues for a first preset time, it is determined that the operating parameters meet the first working state.

[0072] In some embodiments, the operating parameters include the roller speed and / or the roller drive motor current. When the roller speed is less than or equal to a preset speed threshold, or the roller drive motor current is greater than or equal to a preset current threshold and remains so for a first preset duration, it is determined that the clothing is heavily entangled, and the operating parameters meet the first working state. For example, when the power of the roller drive motor is set to remain constant, the working state is determined by the roller speed; when the roller speed is set to remain constant, the working state is determined by the roller drive motor current. The first preset duration can be set according to actual needs; for example, the first preset duration can be 1 minute.

[0073] S52, when the drum speed is greater than the preset speed threshold, or the drum drive motor current is less than the preset current threshold and continues for a second preset time, it is determined that the operating parameters meet the second working state.

[0074] In some embodiments, when the drum rotation speed is greater than a preset rotation speed threshold and the above state continues for a second preset duration, or when the drum drive motor current is less than a preset current threshold and the above state continues for a second preset duration, it is determined that the clothing is slightly tangled or not tangled, and the operating parameters are determined to meet the second working state. The second preset duration is pre-set, for example, 10 minutes.

[0075] This application embodiment determines the working state of the garment processing equipment by the relationship between the drum speed and a preset speed threshold or the relationship between the drum drive motor current and a preset current threshold. The method of obtaining the drum speed and the drum drive motor current is simple and can simplify the efficiency of obtaining the working state. Thus, when the clothes inside the drum become tangled, the untangling operation is performed in a timely manner, further ensuring the drying effect of the garment processing equipment.

[0076] In some embodiments, a working status detection process is also provided, which can be applied to garment processing equipment and includes the following steps:

[0077] S53, when the speed change amplitude of the drum rotation is greater than or equal to a preset speed change threshold, or the current change amplitude of the drum drive motor current is greater than or equal to a preset current change threshold and continues for a third preset duration, it is determined that the operating parameters meet the first working state.

[0078] In some embodiments, the rotational speed change amplitude is the change in rotational speed of the roller within one rotation cycle. The start and end times of one rotation cycle are recorded, and the starting roller speed corresponding to the start time and the ending roller speed corresponding to the end time are determined respectively. The change in rotational speed between the starting and ending roller speeds is calculated as the rotational speed change amplitude. Similarly, the current change amplitude is the change in the current of the roller drive motor within one rotation cycle. The start and end times of one rotation cycle are recorded, and the starting current corresponding to the start time and the ending current corresponding to the end time are determined respectively. The change in current between the starting and ending currents is calculated as the current change amplitude. Both the preset rotational speed change threshold and the preset current change threshold are pre-set values ​​used to assess the degree of clothing entanglement. The third preset duration can be set according to actual needs; for example, the third preset duration can be 1 minute.

[0079] S54, when the speed change amplitude of the drum rotation is less than the preset speed change threshold or the current change amplitude of the drum drive motor is less than the preset current change threshold, and this continues for a fourth preset duration, it is determined that the operating parameters meet the second working state.

[0080] In some embodiments, the fourth preset duration can be set according to actual needs; for example, the fourth preset duration can be 5 minutes.

[0081] In this embodiment, the amplitude of rotation speed change or current change is collected in each rotation cycle, which can determine the working status of the garment processing equipment corresponding to each rotation cycle in a timely manner. Thus, when the clothes in the drum become tangled, the untangling operation is performed in a timely manner, further ensuring the drying effect of the garment processing equipment.

[0082] Figure 6 This is a flowchart illustrating the random triggering of an untangling instruction provided in an embodiment of this application. This random triggering process for the untangling instruction can be applied to garment processing equipment. Figure 6 As shown, it includes the following steps:

[0083] S61, determine the weight of the clothes inside the drum.

[0084] The method for obtaining the weight of the clothes inside the drum has been described in detail in step S41 above, and will not be repeated here.

[0085] S62 determines the probability of triggering the untangling command based on the weight of the clothing.

[0086] In some embodiments, a greater weight of clothing indicates a larger quantity of clothing in the drum, increasing the likelihood of tangling. When randomly triggering an untangling command, the probability of triggering the command should be set to a higher value, ensuring a higher probability of untangling the clothing in the drum. Conversely, a smaller weight of clothing indicates a smaller quantity of clothing in the drum, decreasing the likelihood of tangling. When randomly triggering an untangling command, the probability of triggering the command should be set to a lower value, ensuring a lower probability of untangling the clothing in the drum.

[0087] In this embodiment of the application, when an unwinding command is randomly triggered, the probability of triggering the unwinding command is determined based on the weight of the clothing. This allows the unwinding operation to be performed through probabilistic events when the clothing is slightly tangled, not tangled, or when a fault is detected, thereby improving the drying efficiency of the clothing processing equipment.

[0088] Figure 7 This is a flowchart illustrating the probability determination of untangling commands provided in this application embodiment. This probability determination process for untangling commands can be applied to garment processing equipment. Figure 7 As shown, it includes the following steps:

[0089] S71, when the weight of the clothing is greater than or equal to the preset value, the set probability is greater than or equal to the preset probability.

[0090] S72, when the weight of the clothing is less than the preset value, the set probability is less than the preset probability.

[0091] In some embodiments, the preset value is a pre-set value used to assess the probability of clothing tangling, and the preset probability is a pre-set probability value, for example, the preset probability can be 0.5. When the weight of the clothing is greater than or equal to the preset value, it indicates that the clothing is more likely to tangle, and the probability of randomly triggering the untangling command is set to a larger value, for example, greater than or equal to the preset probability of 0.5, which can be 0.5, 0.6, 0.7, 0.8, etc., without limitation. When the weight of the clothing is less than the preset value, it indicates that the clothing is less likely to tangle, and the probability of randomly triggering the untangling command is set to a smaller value, for example, less than the preset probability of 0.5, which can be 0.4, 0.3, 0.2, etc., without limitation.

[0092] In some embodiments, there is a mapping relationship between clothing weight and a set probability. By querying this mapping relationship, the set probability corresponding to a given clothing weight can be obtained.

[0093] In this embodiment, when an untangling command is randomly triggered, the probability of triggering the untangling command is determined based on the weight of the clothing. This results in a higher probability of triggering the untangling command for heavier clothing and a lower probability for lighter clothing, thus improving the accuracy of setting the probability of triggering the untangling command. This improves the drying efficiency of the clothing processing equipment when the clothing is only slightly tangled, not tangled, or when a fault is detected.

[0094] Figure 8 This is a flowchart illustrating the determination of the rotation rhythm provided in an embodiment of this application. The process for determining the rotation rhythm can be applied to garment processing equipment. Figure 8 As shown, it includes the following steps:

[0095] S81, obtain the forward / reverse switching frequency and / or starting acceleration corresponding to the drum drive motor.

[0096] In some embodiments, when clothing becomes tangled inside the drum, an untangling operation is required. The rotation rhythm of the untangling operation differs from that during normal drum operation. For example, if the drum's normal rotation direction is a forward-reverse cycle, the untangling operation also operates in a forward-reverse direction. Therefore, when performing the untangling operation, the forward / reverse switching frequency and / or starting acceleration during normal drum operation must first be obtained to adjust the untangling rotation rhythm. The forward / reverse switching frequency and / or starting acceleration corresponding to reverse rotation of the drum drive motor will vary depending on the degree of tangling of the clothing inside the drum.

[0097] S82, determine the first rotational beat and the second rotational beat based on the forward / reverse switching frequency and / or the starting acceleration; wherein the forward / reverse switching frequency of the first rotational beat is greater than the forward / reverse switching frequency of the second rotational beat; and / or, the starting acceleration of the first rotational beat is greater than the starting acceleration of the second rotational beat.

[0098] In some embodiments, the first rotation beat and the second rotation beat may include one or both of the forward / reverse switching frequency and the starting acceleration. The first rotation beat is used to untangle heavily tangled clothing, and the second rotation beat is used to untangle lightly tangled or untangled clothing. Therefore, the forward / reverse switching frequency of the first rotation beat is greater than that of the second rotation beat; and / or, the starting acceleration of the first rotation beat is greater than that of the second rotation beat.

[0099] In this embodiment, the first and second rotation beats are determined based on the operating state of the operating parameters. The first rotation beat in the first operating state is greater than the second rotation beat in the second operating state, so that the drum drive motor can untangle clothes with different degrees of entanglement according to the appropriate rotation beat, thereby improving the untangling effect and further ensuring the drying effect of the clothes processing equipment.
