Description

Technical Field

[0001] This application relates to the field of clothing processing device technology, specifically to a control method for a clothing processing device and a clothing processing device. Background Technology

[0002] With the development of technology, garment processing devices have entered thousands of households. However, during the operation of garment processing devices, if there are too many or too wet clothes in the drum, resulting in excessive load or malfunction of the tension wheel or spring, the tension of the transmission device will decrease. This will cause the maximum friction between the transmission device and the drive device or the drum to be insufficient to drive the drum to rotate, resulting in sliding friction in the transmission device. Consequently, the transmission device will be burned out by the heat generated by the sliding friction.

[0003] Therefore, how to prevent the transmission device from breaking due to sliding friction is an urgent problem that needs to be solved. Summary of the Invention

[0004] The purpose of this application is to resolve the above-mentioned problems and other issues.

[0005] The purpose of this application is also to determine whether sliding friction occurs in the transmission device based on the drum rotation speed during the garment processing start-up phase.

[0006] The purpose of this application is also to determine whether sliding friction occurs in the transmission device based on the fluctuation of the output power of the drive device during the operation of the clothing processing procedure.

[0007] The purpose of this application is also to resolve the sliding friction of the transmission device by reducing the weight of the roller and the clothes to be processed after sliding friction occurs in the transmission device.

[0008] The purpose of this application is also to determine the cause of sliding friction in the transmission device after sliding friction occurs.

[0009] The purpose of this application is also to provide a garment handling device equipped with a tension wheel and a tension spring to control the tightness of the transmission device.

[0010] In a first aspect, this application provides a garment processing apparatus for achieving the above-mentioned objective, comprising: a body for forming the outer shell of the garment processing apparatus; a roller disposed within the body for accommodating garments to be processed; and a drive device disposed within the body, the drive device being used to drive the roller to rotate via a transmission device.

[0011] The control method includes: controlling the drive device to drive the drum to rotate via the transmission device according to a preset clothing processing program; after the drum's rotational speed reaches the drum rotational speed corresponding to the clothing processing program, acquiring the output power fluctuation of the drive device; if the output power fluctuation is less than a preset fluctuation threshold, determining that sliding friction occurs between the drive device and / or the drum and the transmission device.

[0012] In this embodiment of the application, during the rotation of the drum in the garment processing device, the distribution of the garments to be processed inside the drum will not be in an ideal state of uniform distribution along the drum wall. That is, the drum must be in an eccentric state relative to the drum axis. During the rotation of the eccentric drum around the drum axis, gravity has two states: positive work and negative work. Therefore, the power required by the drive device to drive the drum to rotate must be variable.

[0013] During the rotation of the drum, if sliding friction occurs in the transmission device, the drive device cannot drive the drum to rotate normally via the transmission device. At this time, the output power of the drive device is approximately equal to the power required to overcome the sliding friction, and is unrelated to the eccentricity of the clothes inside the drum. Therefore, the friction fluctuation is very small, resulting in a very small fluctuation in the output power of the drive device. Based on this principle, it is possible to detect in a timely manner that, during the operation of the garment processing program, if the fluctuation in the output power of the drive device is less than the fluctuation threshold, it is determined that sliding friction has occurred in the transmission device. The garment processing device can then be controlled to stop the drum rotation to avoid potential damage to the transmission device. This also prevents economic losses or a poor user experience.

[0014] In one embodiment of this application, after controlling the drive device to drive the roller to rotate via the transmission device according to the preset clothing processing program, the method further includes: after starting the clothing processing program for a first set time, if the rotational speed of the roller does not reach the roller rotational speed corresponding to the clothing processing program, then determining that sliding friction occurs between the drive device and / or the roller and the transmission device.

[0015] In this embodiment, considering that sliding friction occurs in the transmission device not only during the operation of the garment processing program but also during the initial startup of the program, each garment processing program has a corresponding roller speed. If no sliding friction occurs in the transmission device during the startup of the garment processing program, the roller speed will increase to the speed corresponding to that program. If, after the garment processing device starts executing the program, the roller speed has not yet reached the speed corresponding to that program, it indicates that sliding friction occurred in the transmission device during the startup phase. The garment processing device is then controlled to stop the roller rotation to avoid potential damage to the transmission device. This also prevents economic losses or a poor user experience.

[0016] In one embodiment of this application, after determining that sliding friction occurs between the drive device and / or the roller and the transmission device, the method further includes: controlling the roller to stop rotating; restarting the garment processing program when the weight reduction of the roller and the garment to be processed is greater than a set weight and / or a restart instruction is detected; and determining the cause of the sliding friction in the transmission device based on the operating status of the garment processing device.

[0017] In this embodiment, whether the garment processing procedure is in the startup or running phase, sliding friction in the transmission device is generally caused by two reasons. First, the total weight of the garments to be processed and the roller is too large; second, component malfunction causes sliding friction in the transmission device. To address these two possibilities, the total weight of the garments to be processed and the roller is reduced, and it is observed whether sliding friction still occurs in the transmission device. This determines whether the sliding friction is caused by the excessive weight of the garments to be processed and the roller. If it is not caused by the excessive weight of the garments to be processed and the roller, it is due to plastic deformation of the tension wheel spring in the transmission device, resulting in a decrease in tension force. By using the above method, the cause of sliding friction between the transmission device and the drive device can be determined. Different solutions exist for different causes, which helps users quickly identify the cause of sliding friction in the transmission device and resolve the situation.

[0018] In one embodiment of this application, after the control of the roller to stop rotating and before restarting the clothing processing program, the method further includes: after the clothing processing device stops operating, allowing it to stand for a second set time and starting the drainage mode; if the total weight of the roller and the clothing to be processed does not decrease by a set weight, then a weight reduction reminder is given to the user.

[0019] In this embodiment, considering that the excessive weight of the garments and drum might be due to high moisture content, a drainage mode is activated to see if the weight can be reduced by allowing the garments to drain. If not, the user needs to manually remove some of the garments to reduce the overall weight. This method increases the automation of the garment processing device, automatically handling some of the sliding friction issues in the transmission mechanism when unattended, significantly improving the user experience.

[0020] In one embodiment of this application, the garment processing device body is further provided with a tension wheel and a tension spring, the tension spring being used to control the movement of the tension wheel, and the tension wheel being used to control the tension of the transmission device.

[0021] In this embodiment, when the garment handling device also includes a tension wheel and a tension spring, the sliding friction in the transmission device may be caused by plastic deformation of the tension wheel and tension spring, resulting in a decrease in the tension force of the transmission device. When sliding friction occurs in the transmission device, the position of the tension wheel can be adjusted to eliminate the sliding friction between the transmission device and the drive device.

[0022] On the other hand, when sliding friction occurs in the transmission device, it is either due to an excessive total weight of the clothes to be processed and the drum, or a malfunction of the tension wheel and / or spring. This makes it easier to identify the cause of the sliding friction in the transmission device.

[0023] In one embodiment of this application, determining the cause of sliding friction in the transmission device based on the operating state of the garment processing device includes: after starting the garment processing program for a first set time, if the rotational speed of the roller reaches the rotational speed corresponding to the garment processing program, then the cause of sliding friction in the transmission device is determined to be that the total weight of the roller and the garment to be processed is too large; if the rotational speed of the roller does not reach the rotational speed corresponding to the garment processing program, then the cause of sliding friction in the transmission device is determined to be a malfunction of the tension spring and / or the tension wheel.

[0024] In this embodiment, when the garment processing program is in the startup phase and sliding friction occurs in the transmission device, the total weight of the garment to be processed and the roller is first reduced, and the garment processing program is restarted. If the roller's rotational speed reaches the rotational speed corresponding to the garment processing program, it is determined that the sliding friction in the transmission device is caused by excessive total weight of the roller and the garment to be processed. If the roller's rotational speed does not reach the rotational speed corresponding to the garment processing program, it is determined that the tension spring and / or tension wheel is faulty. This method clearly informs the user of the reason for the sliding friction in the transmission device when the garment processing program is started, facilitating further processing by the user to eliminate the sliding friction in the transmission device.

[0025] In one embodiment of this application, determining the cause of sliding friction in the transmission device based on the operating state of the garment processing device further includes: acquiring the output power fluctuation of the drive device; if the output power fluctuation is always greater than or equal to a preset fluctuation threshold, then determining that the cause of sliding friction in the transmission device is that the total weight of the roller and the garment to be processed is too large; if the output power fluctuation is less than the preset fluctuation threshold, then determining that the cause of sliding friction in the transmission device is that the tension spring and / or tension wheel is malfunctioning.

[0026] In this embodiment, when the garment processing program is running, if sliding friction occurs in the transmission device, the total weight of the garment to be processed and the roller is first reduced, and the garment processing program is restarted. If the output power fluctuation is consistently less than a preset fluctuation threshold, meaning the transmission device no longer experiences sliding friction, then the sliding friction is determined to be caused by excessive total weight of the roller and the garment to be processed. If the output power fluctuation is greater than or equal to the preset fluctuation threshold, then the tension spring and / or tension wheel is determined to be faulty. This method clearly informs the user of the cause of sliding friction in the transmission device during the garment processing program, facilitating further processing by the user to eliminate the sliding friction in the transmission device.

[0027] Secondly, one embodiment of this application provides a garment processing device. The garment processing device includes: a body for forming the outer shell of the garment processing device; a roller disposed in the body for accommodating garments to be processed; a drive device disposed in the body, the drive device being used to drive the roller to rotate via a transmission device; and a controller, the controller including: a start unit configured to control the drive device to drive the roller to rotate via the transmission device according to a preset garment processing program; an acquisition unit configured to acquire the output power fluctuation of the drive device after the rotational speed of the roller reaches the rotational speed corresponding to the garment processing program; and a judgment unit configured to determine that sliding friction occurs between the drive device and / or the roller and the transmission device if the output power fluctuation is less than a preset fluctuation threshold.

[0028] In this embodiment of the application, during the rotation of the drum in the garment processing device, the distribution of the garments to be processed inside the drum will not be in an ideal state of uniform distribution along the drum wall. That is, the drum must be in an eccentric state relative to the drum axis. During the rotation of the eccentric drum around the drum axis, gravity has two states: positive work and negative work. Therefore, the power required by the drive device to drive the drum to rotate must be variable.

[0029] In one embodiment of this application, the controller is further configured as: a second judgment unit, configured to determine that sliding friction occurs between the drive device and / or the roller and the transmission device if the rotational speed of the roller does not reach the rotational speed corresponding to the garment processing program after the garment processing program is started for a first set time.

[0030] In this embodiment, considering that sliding friction occurs in the transmission device not only during the operation of the garment processing program but also during the initial startup of the program, each garment processing program has a corresponding roller speed. If no sliding friction occurs in the transmission device during the startup of the garment processing program, the roller speed will increase to the speed corresponding to that program. If, after the garment processing device starts executing the program, the roller speed has not yet reached the speed corresponding to that program, it indicates that sliding friction occurred in the transmission device during the startup phase. The garment processing device is then controlled to stop the roller rotation to avoid potential damage to the transmission device. This also prevents economic losses or a poor user experience.

[0031] In one embodiment of this application, the controller is further configured as: a stop unit configured to control the roller to stop rotating; a detection unit configured to restart the garment processing program when the reduced weight of the roller and the garment to be processed is greater than a set weight and / or a restart instruction is detected; and a determination unit configured to determine the cause of sliding friction in the transmission device based on the operating state of the garment processing device.

[0032] In this embodiment, whether the garment processing procedure is in the startup or running phase, sliding friction in the transmission device is generally caused by two reasons. First, the total weight of the garments to be processed and the roller is too large; second, component malfunction causes sliding friction in the transmission device. To address these two possibilities, the total weight of the garments to be processed and the roller is reduced, and it is observed whether sliding friction still occurs in the transmission device. This determines whether the sliding friction is caused by the excessive weight of the garments to be processed and the roller. If it is not caused by the excessive weight of the garments to be processed and the roller, it is due to plastic deformation of the tension wheel spring in the transmission device, resulting in a decrease in tension force. By using the above method, the cause of sliding friction between the transmission device and the drive device can be determined. Different solutions exist for different causes, which helps users quickly identify the cause of sliding friction in the transmission device and resolve the situation.

[0043] Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0044] This application provides a garment processing device, including a body, a drum, and a drive device.

[0045] The machine body serves as the outer shell of the garment processing device, and its interior forms an installation space for mounting the rollers. The rollers are housed within the machine body. The rollers provide processing space for the garments to be processed. A transmission device is also located within the machine body. This transmission device connects the rollers and a drive device. The drive device, also located within the machine body, drives the rollers to rotate via the transmission function of the transmission device.

[0046] Please see Figure 1 , Figure 1 A schematic diagram of a garment processing apparatus according to an embodiment of this application is shown. The garment processing apparatus includes a main body, a roller, a transmission device, a drive device (not shown), a tension spring, and a tension wheel.

[0047] Based on the above clothing processing device, such as Figure 2 As shown, Figure 2 A flowchart illustrating a control method for a garment handling apparatus according to an embodiment of this application is shown. This application provides the steps of a control method for a garment handling apparatus, including:

[0048] Step S210: According to the preset clothing processing program, control the drive device to drive the drum to rotate via the transmission device;

[0049] Step S220: After the rotational speed of the drum reaches the drum rotational speed corresponding to the clothing processing program, the output power fluctuation of the drive device is obtained.

[0050] In step S230, if the output power fluctuation is less than the preset fluctuation threshold, it is determined that sliding friction occurs between the drive device and / or the roller and the transmission device.

[0051] The above three steps are described in detail below.

[0052] Before describing the above three steps in detail, it should be noted that during the operation of the garment processing device, the distribution of the garments to be processed inside the drum will not be in an ideal state of uniform distribution along the drum wall. That is, the drum must be in an eccentric state relative to the drum axis. During the rotation of the eccentric drum around the drum axis, gravity has two states: positive work and negative work. Therefore, the power required to drive the drum to rotate must be variable, as the drive device transmits power through the transmission device.

[0053] However, during the garment processing procedure in the garment handling device, if sliding friction occurs in the transmission device while the drum is rotating, the drive unit cannot drive the drum to rotate via the transmission device. In this case, the motor output power equals the power required to overcome the sliding friction of the transmission device, and is unrelated to the degree of eccentricity of the garments inside the drum. Simultaneously, during the sliding friction process, the temperature of the transmission device will not rise excessively in a short period, having minimal impact on its mechanical properties. Because the fluctuation of the sliding friction force during the sliding friction of the transmission device is very small, the fluctuation of the motor output power is also very small.

[0054] In other words, when there is no sliding friction in the transmission device, the distribution of the clothes to be processed inside the drum will not be in an ideal, uniform distribution along the drum wall; the drum will inevitably be in an eccentric state relative to the drum axis. This results in a large fluctuation in the output power of the drive device. However, when sliding friction occurs in the transmission device of the clothing processing device, the sliding friction force is relatively stable, resulting in a very small fluctuation in the output power of the drive device.

[0055] It needs to be clarified that sliding friction in the transmission device may occur between the transmission device and the drive device, between the transmission device and the roller, or between the transmission device and the roller simultaneously.

[0056] In step S210, based on the user's instruction information, the garment processing device selects a preset garment processing program and starts it. During the program's startup phase, the drive device, through the transmission function of the transmission device, drives the roller to rotate according to the requirements of the garment processing program. The garment processing program starts normally and enters the running phase. Normal startup means that all parameters in the garment processing device meet the parameter standards of the garment processing program, such as the roller speed. This process is called the startup phase of the garment processing program. After all parameters in the garment processing device meet the parameter standards of the garment processing program, the garment processing program enters the running phase.

[0057] In one embodiment of this application, during the garment processing program's startup phase, the roller speed is intermittently acquired, such as at set time intervals. If, within a first set time interval after the garment processing program starts, the maximum value of the roller speed reaches the roller speed corresponding to the garment processing program, then the garment processing program is considered to have started normally. The first set time interval refers to the duration for starting the garment processing program. It should be clarified that the maximum value of the roller speed refers to: firstly, the maximum value that the roller speed can reach when the roller rotates periodically (e.g., intermittent same-direction rotation, intermittent opposite-direction rotation); and secondly, the maximum value that the roller speed can reach when the roller rotates continuously in the same direction.

[0058] When the roller's rotation speed reaches the speed corresponding to the garment processing program, it indicates that no sliding friction has occurred in the transmission device. If the roller's rotation speed does not reach the speed corresponding to the garment processing program, it indicates that sliding friction has occurred in the transmission device, preventing the drive unit from using the transmission function to drive the roller to the speed corresponding to the garment processing program. In this case, if the garment processing program continues to run, the transmission device will burn out. Therefore, the garment processing program is stopped, causing the roller to stop rotating and preventing economic losses for the user.

[0059] In this embodiment, considering that the period of sliding friction in the transmission device can occur not only during the operation phase of the garment processing program, but also during the startup phase of the garment processing program. Each garment processing program has a corresponding roller speed. If the garment processing program is operating normally, the roller speed will increase to the roller speed corresponding to the garment processing program. If, within the first set time after the garment processing device starts executing the garment processing program, the roller speed does not reach the roller speed corresponding to the garment processing program, it indicates that sliding friction has occurred in the transmission device during the startup phase of the garment processing program.

[0060] In response to this situation, the garment handling device is stopped from executing the garment handling program to prevent the transmission mechanism from burning out. This more comprehensively avoids causing economic losses or a poor user experience.

[0061] In step S220, after the garment processing program starts normally, that is, after the drum speed reaches the drum speed corresponding to the garment processing program, the garment processing program enters the running stage, and the output power fluctuation of the drive device during the operation of the garment processing program is acquired. Specifically, the output power of the drive device is recorded at a certain time point, and the output power of the drive device is recorded again at a set time interval. The difference between the two output power values ​​of the drive device is the output power fluctuation.

[0062] When preparing to acquire the next output power fluctuation, the starting time point is the last time the output power was acquired, and the starting output power is the output power of the last acquired drive device. Then, the output power of the drive device is acquired again at set intervals, and this is taken as the ending output power. The difference between the starting output power and the ending output power is taken as the output power fluctuation.

[0063] Specifically, the output power of a drive device is acquired at set intervals, and the difference between the output power and the adjacent output power is calculated to obtain the output power fluctuation.

[0064] In another embodiment of this application, the output power of the drive device can be obtained in real time by setting a standard output power, and the difference between the output power of the drive device and the standard output power is the output power fluctuation.

[0065] In step S230, it is detected whether the newly acquired output power fluctuation is less than a preset fluctuation threshold. If the output power fluctuation is less than the preset fluctuation threshold, it indicates that sliding friction has occurred between the transmission device and the drive device. If the garment processing device continues to run the garment processing program at this time, it may cause damage to the transmission device, increasing the risk of damage to the user's property. Therefore, once the output power fluctuation is less than the preset fluctuation threshold, the garment processing device is immediately stopped from running the garment processing program to stop the rotation of the drum.

[0066] Please see Figure 3 , Figure 3 A flowchart illustrating the determination of the cause of sliding friction in a transmission device according to an embodiment of this application is shown. Embodiments of this application provide steps for determining the cause of moving friction in a transmission device, including:

[0067] Step S301: Control the roller to stop rotating;

[0068] Step S302: When the reduced weight of the roller and the clothes to be processed is greater than the set weight and / or a restart instruction is detected, the clothes processing program is restarted.

[0069] Step S303: Determine the cause of sliding friction in the transmission device based on the operating status of the garment processing device.

[0070] The above three steps are described in detail below.

[0071] In step S301, whether in the garment processing program startup phase or the garment processing program operation phase, as soon as sliding friction is detected in the transmission device, the garment processing device is immediately stopped from running the garment processing program to stop the rotation of the roller.

[0072] In step S302, after stopping the garment processing program, since the cause of the sliding friction in the transmission device is unknown, it is possible that the combined weight of the roller and the garment to be processed is too high. Reducing the combined weight of the roller and the garment to be processed may resolve the sliding friction issue in the transmission device. If the sliding friction issue in the transmission device cannot be resolved, it indicates a malfunction in one of the components of the garment processing device itself.

[0073] The following solutions are available to address the above situation.

[0074] Before reducing the total weight of the rollers and the clothes to be processed, considering the possibility of a temporary malfunction in the garment processing unit, the garment processing program was directly restarted based on the user's instructions. After restarting the garment processing program, if no sliding friction occurred in the transmission device during the startup and operation phases, then the cause of the sliding friction in the transmission device during the previous operation of the garment processing program was determined to be a temporary malfunction in the garment processing unit. Otherwise, the sliding friction in the transmission device may be due to an excessive total weight of the rollers and the clothes to be processed, or a malfunction in a component within the garment processing unit.

[0075] The first method involves the user reducing the amount of clothing to be processed in the drum, and then restarting the clothing processing program based on the user's instructions or a restart event.

[0076] If sliding friction still occurs in the transmission device, it indicates that the total weight of the roller and the clothes to be processed has not been reduced sufficiently. The user should be further reminded to reduce the total weight of the roller and the clothes to be processed. Continue removing the clothes to be processed.

[0077] Until the total weight of the roller and the clothes to be processed is reduced to the weight threshold, if the transmission device still experiences sliding friction during the start-up or operation phase of the garment processing program, it indicates that the sliding friction of the transmission device is not caused by the excessive total weight of the roller and the clothes to be processed, but by a malfunction of the garment processing device.

[0078] The start event refers to the automatic restart of the clothing processing program if the clothing processing device detects a decrease in the total weight of the roller and the clothes to be processed, and has not received the user's instruction information after a set time.

[0079] In one embodiment of this application, after the garment processing program stops running and the drum stops rotating, and before manually reducing the amount of garment to be processed, the garment is left to stand for a second predetermined time while the drainage mode is activated. This is because the garment has a high moisture content, which would result in an excessive total weight of the drum and the garment. Therefore, the garment is left to stand for a second predetermined time to reduce the moisture content of the garment, thereby reducing the total weight of the drum and the garment.

[0080] If no decrease in the total weight of the roller and the clothes to be processed is detected, it indicates that the clothes contain little moisture, and the total weight of the roller and the clothes cannot be reduced by draining water. Therefore, the user will be reminded that the garment processing device is currently in a state where it cannot automatically reduce weight, and the user needs to manually reduce the total weight of the roller and the clothes to be processed.

[0081] Secondly, considering that reducing the total weight of the roller and the clothes to be processed by a small amount might not eliminate sliding friction, and if the reduction is too small, the sliding friction of the transmission device cannot be eliminated, leading to repeated restarts of the garment processing program, which could damage the transmission device and reduce its lifespan. Therefore, the total weight of the roller and the clothes to be processed in the garment processing device must be reduced by at least a set weight to meet the requirement of restarting the garment processing program. After meeting the requirement of restarting the garment processing program, it can start automatically based on a start event or based on user instructions.

[0082] Similarly, in this case, the amount of clothing to be processed can be reduced multiple times, with each reduction being at least the set weight, until the total weight of the roller and the clothing to be processed is reduced to the weight threshold. If the transmission device still experiences sliding friction during the start-up or operation phase of the clothing processing program, it indicates that the sliding friction of the transmission device is not caused by the excessive total weight of the roller and the clothing to be processed, but by a malfunction in the clothing processing device.

[0083] Furthermore, in the above-described scenario, after the garment processing program stops running and the drum stops rotating, before manually reducing the amount of garment to be processed, allow the garment to stand for a second set time and activate the drainage mode. If the total weight of the drum and the garment to be processed does not decrease by the set amount, it indicates that the garment contains relatively little moisture. The user will then be alerted that the garment processing device is currently unable to automatically reduce weight and requires manual reduction of the total weight of the drum and the garment to be processed.

[0084] In step S303, the cause of sliding friction in the transmission device is determined based on the state of the garment processing device when it runs the garment processing program.

[0085] Specifically, if no sliding friction occurs in the transmission device during the startup and operation phases of the garment processing program after the garment processing device restarts the garment processing program, it indicates that the sliding friction in the transmission device of the garment processing device before this was caused by the excessive total weight of the roller and the garment to be processed.

[0086] If sliding friction occurs in the transmission device during the start-up or operation phase of the garment processing program, it indicates that the cause is not due to excessive weight of the rollers and the garments being processed, but rather a malfunction in a part of the garment processing device. Repair is required. Therefore, in this situation, the garment processing device will issue a warning message to the user through means including but not limited to lights, audio, and text, indicating that repair is needed.

[0087] In one embodiment of this application, the garment processing device may include a tension wheel and a tension spring within its body. The tension spring can be used to control the movement of the tension wheel. The tension wheel can be used to control the tension of the drive device. If it is determined that the sliding friction in the transmission device is caused by the excessive total weight of the roller and the garments being processed, the tension wheel can be moved by controlling the tension spring. This tension wheel further tightens the transmission device, generating greater pressure on the roller or drive device. Consequently, the sliding friction requires overcoming a greater frictional force, reducing the likelihood of sliding friction in the transmission device.

[0088] This structure also helps to further determine the cause of sliding friction in the transmission device. For example, if the tension spring malfunctions and cannot secure the tension wheel, the transmission device will become loose, leading to sliding friction. Sliding friction in the transmission device caused by this reason requires professional repair by maintenance personnel.

[0089] Please see Figure 4 , Figure 4 A flowchart illustrating the determination of the cause of sliding friction in the transmission device based on the operating state of the garment handling apparatus during the garment handling process initiation phase, according to another embodiment of this application, is provided. This application embodiment provides step S303, which includes determining the cause of sliding friction in the transmission device based on the operating state of the garment handling apparatus, comprising:

[0090] Step S401: After the first set time of starting the garment processing program, if the rotation speed of the roller reaches the roller rotation speed corresponding to the garment processing program, it is determined that the reason for the sliding friction of the transmission device is that the total weight of the roller and the garment to be processed is too large.

[0091] In step S402, if the rotational speed of the roller does not reach the rotational speed corresponding to the garment processing program, it is determined that the cause of sliding friction in the transmission device is a malfunction of the tension spring and / or the tension wheel.

[0092] The two steps described above are described in detail below.

[0093] This addresses the issue of sliding friction occurring in the transmission device during the initiation phase of the garment processing procedure.

[0094] In step S401, regarding the startup phase of the garment processing program, when sliding friction occurs in the transmission device, the garment processing program stops running. Then, following the triggering condition in step S301, the garment processing program restarts. If the roller's rotational speed reaches the corresponding roller speed for the garment processing program during startup, it indicates that no friction occurred in the transmission device during the startup phase. This demonstrates that the technical means employed in step S301, namely reducing the total weight of the roller and the garment to be processed, prevents sliding friction from occurring during the startup phase. Therefore, it can be concluded that the reason for sliding friction in the transmission device during the startup phase of the garment processing program is that the total weight of the roller and the garment to be processed is too large.

[0095] In step S402, the garment processing program is restarted. If the garment processing program does not reach the corresponding roller speed during startup, this indicates that the technical means employed in step S301, namely reducing the total weight of the roller and the garment to be processed, cannot prevent sliding friction during the startup phase. Therefore, the reason for sliding friction in the transmission device during the startup phase is not that the total weight of the roller and the garment is too large. That is, the reason for sliding friction in the transmission device during the startup phase is a malfunction of the tension spring or the tension wheel, preventing the transmission device from tightening and causing sliding friction during the startup phase.

[0096] In response to this situation, the garment processing device prompts the user that professional repair personnel are required for maintenance, and that the user should not attempt repairs themselves to avoid further damage to the device. In one embodiment of this application, the garment processing device also uploads the fault information to the cloud to remind maintenance personnel to promptly address the issue, contact the user, and expedite repairs to improve the user experience.

[0097] In one embodiment of this application, during the garment processing initiation phase, to determine whether sliding friction in the transmission device is caused by a malfunction of the tension spring and / or tension wheel, the total weight of the roller and the garments to be processed must reach a weight threshold. That is, only when the total weight of the roller and the garments to be processed is reduced to below the weight threshold, and sliding friction in the transmission device occurs, can it be determined that the sliding friction is caused by a malfunction of the tension spring and / or tension wheel. This is because if the total weight of the roller and the garments to be processed is not reduced to below the weight threshold, it is also possible that the total weight of the roller and the garments to be processed is too large, causing sliding friction in the transmission device.

[0098] Please see Figure 5 , Figure 5A flowchart illustrating the determination of the cause of sliding friction in the transmission device based on the operating state of the garment processing apparatus during the garment processing phase according to an embodiment of this application is provided. This embodiment of the application provides step S303, which includes determining the cause of sliding friction in the transmission device based on the operating state of the garment processing apparatus, comprising:

[0099] Step S501: Obtain the output power fluctuation of the drive device;

[0100] Step S502: If the output power fluctuation is always greater than or equal to the preset fluctuation threshold, it is determined that the cause of the sliding friction in the transmission device is that the total weight of the roller and the clothes to be processed is too large.

[0101] In step S503, if the output power fluctuation is less than the preset fluctuation threshold, it is determined that the cause of the sliding friction in the transmission device is a malfunction of the tension spring and / or the tension wheel.

[0102] The above three steps are described in detail below.

[0103] This addresses the issue of sliding friction occurring in the transmission device during the garment processing phase.

[0104] During the operation of the garment processing program, when sliding friction occurs in the transmission device, the garment processing program stops running, reducing the total weight of the roller and the garment to be processed. Then, after the triggering condition in step S301, the garment processing program is restarted. If the roller speed corresponding to the garment processing program is reached during the startup process, it indicates that there is no friction in the transmission device during the startup phase of the garment processing program.

[0105] In step S501, the clothing processing program enters the running stage and acquires the output power fluctuation of the drive device.

[0106] In step S502, if the output power fluctuation is always greater than or equal to the preset fluctuation threshold, it is determined that the transmission device has not experienced sliding friction. This indicates that the reason for the sliding friction in the transmission device during the previous operation of the clothing processing program was that the total weight of the roller and the clothing to be processed was too large.

[0107] In step S503, if the output power fluctuation is less than the preset fluctuation threshold, it is determined that the drive device still experiences sliding friction. This indicates that the reason for the sliding friction in the transmission device during the previous operation of the garment processing program was not that the total weight of the roller and the garment to be processed was too large. In other words, the reason for the sliding friction in the transmission device during the operation of the garment processing program is a malfunction of the tension spring or the tension wheel, preventing the transmission device from tightening and causing sliding friction in the transmission device during the start-up phase of the garment processing program.

[0108] In response to this situation, the garment processing device prompts the user that professional repair personnel are required for maintenance, and that the user should not attempt repairs themselves to avoid further damage to the device. In one embodiment of this application, the garment processing device also uploads the fault information to the cloud to remind maintenance personnel to promptly address the fault, contact the user, and expedite repairs, thus improving the user experience.

[0109] In one embodiment of this application, during the clothing processing stage, when it is determined that sliding friction in the transmission device is caused by a malfunction of the tension spring and / or tension wheel, the total weight of the roller and the clothing to be processed needs to reach a weight threshold. That is, only when the total weight of the roller and the clothing to be processed is reduced to below the weight threshold, and sliding friction in the transmission device occurs, can it be determined that the sliding friction is caused by a malfunction of the tension spring and / or tension wheel. This is because if the total weight of the roller and the clothing to be processed is not reduced to below the weight threshold, it is also possible that the total weight of the roller and the clothing to be processed is too large, causing sliding friction in the transmission device.

[0110] It should be clarified that in one embodiment of this application, sliding friction may occur in the transmission device during the initial stage of the garment processing program. By reducing the total weight of the roller and the garments to be processed, sliding friction in the transmission device can be prevented during the initial stage. If sliding friction occurs again during the operation of the garment processing program, the aforementioned technical means are used to further reduce the total weight of the roller and the garments to be processed to determine the cause of the sliding friction in the drive device. This allows users to determine appropriate solutions based on various causes, such as professional repairs or changing the position of the tension wheel, to resolve the problem of sliding friction in the drive device.

[0111] In another embodiment of this application, sliding friction may occur in the transmission device initially during the garment processing phase. However, by reducing the total weight of the roller and the garments to be processed, sliding friction may occur again during the initial stage of the garment processing. In this case, the total weight of the roller and the garments to be processed is further reduced using the aforementioned technical means to determine the cause of the sliding friction in the drive device. This allows users to determine appropriate solutions based on the various causes, such as performing professional repairs or changing the position of the tension wheel, to resolve the problem of sliding friction in the drive device.

[0112] In one embodiment of this application, a garment processing device is also disclosed, including a body, a roller, and a drive device.
