Technical Field

[0001] This application relates to the field of fault detection technology, and includes, but is not limited to, a detection method, apparatus, clothing processing equipment, and computer-readable storage medium. Background Technology

[0002] Because dryers and washer-dryer combos have advantages such as disinfection, sterilization, convenience, and hygiene, clothing processing equipment such as dryers and washer-dryer combos are becoming increasingly popular.

[0003] In practice, to improve the uniformity of drying and avoid tangling, a flap structure is installed on the dryer or washer-dryer combo to increase the reverse airflow, thereby improving the uniformity of drying and preventing clothes from tangling.

[0004] However, the gap between the flap structure, which is a rotating component, and the back cover is small. During the rotation process, the flap structure is prone to jamming, which leads to prolonged drying time and even damage to the compressor, thereby shortening the service life of clothing processing equipment such as dryers and washer-dryer combos.

[0010] Once the first current temperature is determined to have reached a temperature threshold, the first temperature change gradient of the cylinder is determined at each first preset time interval.

[0011] If the first temperature change gradient is determined to be less than the reference gradient threshold, it is determined that there is an abnormality in the flip-plate structure of the clothing processing equipment.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0029] In the following description, the terms "first, second, third" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0030] 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 embodiments of this application only and is not intended to limit this application.

[0031] To address the problems existing in related technologies, this application provides a detection method. This method can be implemented by a computer program, which, when executed, performs the detection method provided in this embodiment. In some embodiments, the computer program can control the processor in a garment processing device. Figure 1 This is a schematic diagram illustrating an implementation flow of the detection method provided in an embodiment of this application, such as... Figure 1 As shown, the detection method includes:

[0032] Step S101: In response to the received start command, control the garment processing equipment to execute the garment processing procedure.

[0033] Here, the start command can be triggered by a received press operation on the physical button of the garment processing device, or by a received touch operation on the start button on the touch screen of the garment processing device; the start command can also be triggered by voice or gesture to start the garment processing device; the start command can also be issued through a smart terminal such as a mobile phone, tablet, or smart wearable device, wherein a communication connection is established between the garment processing device and the smart terminal.

[0034] In practice, the garment processing equipment can be a dryer, washer-dryer combo, or clothes dryer, etc., and is used to dry the garments to be processed.

[0035] In this embodiment of the application, after receiving the above-mentioned start command, in response to the start command, the compressor of the clothing processing device is started, and the motor of the clothing processing device is also controlled to start rotating, so that the clothing processing device executes the clothing processing program, wherein the clothing processing program can be a drying program.

[0036] Step S102: Obtain the first current temperature of the drum of the garment processing equipment.

[0037] Obtaining the first current temperature of the garment processing equipment's drum can be achieved by acquiring the temperature collected by a temperature sensor used to monitor the drum's temperature. In practical applications, this temperature sensor can be installed on the drum of the garment processing equipment; in some embodiments, the temperature sensor can also be installed in the air inlet or outlet duct of the garment processing equipment, and the temperature of the air inlet or outlet duct can be monitored to determine the first current temperature of the drum.

[0038] Step S103: Determine that the first current temperature has reached the temperature threshold, and determine the first temperature change gradient of the cylinder at each first preset time interval.

[0039] Here, the temperature threshold can be the factory default value, which can be a Celsius value, such as 25 degrees Celsius, 26 degrees Celsius, 29 degrees Celsius, etc.; the temperature threshold can also be a Celsius range, such as 25 degrees Celsius to 30 degrees Celsius.

[0040] In this embodiment, it can be determined whether the first current temperature has reached a temperature threshold, that is, whether the first current temperature is greater than or equal to the temperature threshold. When the temperature threshold is a temperature value (point value), the relationship between the first current temperature and the temperature threshold can be directly determined. When the temperature threshold is a temperature range (interval value), the relationship between the first current temperature and the smaller temperature value (lower lower limit value) in the temperature range is determined. If the first current temperature is greater than or equal to the smaller temperature value in the temperature range, then the first current temperature is considered to have reached the temperature threshold.

[0041] Taking the temperature threshold as an example, if the first current temperature is less than the temperature threshold, it is determined that the first current temperature has not reached the temperature threshold, and the first current temperature can continue to be obtained, that is, return to step S102; while if the first current temperature is greater than or equal to the temperature threshold, it is determined that the first current temperature has reached the temperature threshold.

[0042] In this embodiment, when the first current temperature reaches a temperature threshold, a first temperature change gradient of the cylinder is determined every first preset time interval. The first preset time interval can be a factory default value or a custom setting. For example, the first preset time interval can be 1.5 minutes, 2 minutes, 2.5 minutes, etc. Generally, the shorter the first preset time interval, the higher the detection accuracy.

[0043] Here, the first temperature change gradient characterizes the rate of temperature change of the cylinder within a first preset time period.

[0044] In some embodiments, if the temperature sensor is installed in the air inlet duct of the garment processing equipment, when the temperature of the air inlet duct reaches the temperature threshold, the temperature change gradient of the air inlet duct can be determined at a first preset time interval, and then the temperature change gradient of the air inlet duct can be determined as the first temperature change gradient of the garment body; if the temperature sensor is installed in the air outlet duct of the garment processing equipment, when the temperature of the air outlet duct reaches the temperature threshold, the temperature change gradient of the air outlet duct can be determined at a first preset time interval, and then the temperature change gradient of the air outlet duct can be determined as the first temperature change gradient of the garment body.

[0045] Step S104: If the first temperature change gradient is less than the reference gradient threshold, it is determined that there is an abnormality in the flip-plate structure of the clothing processing equipment.

[0046] Here, the magnitude comparison method can be used to determine the relationship between the first temperature change gradient and the reference gradient threshold. If it is determined that the first temperature change gradient is less than the reference gradient threshold, it indicates that the flap structure of the clothing processing equipment may be stuck, thus confirming that the flap structure of the clothing processing equipment is abnormal. If the first temperature change gradient is greater than or equal to the reference gradient threshold, it indicates that the flap structure of the clothing processing equipment is operating normally and there is no stuck problem, thus confirming that the flap structure of the clothing processing equipment is in a normal state.

[0047] The reference gradient threshold is generally set to a default value, which can be 0, 0.01, 0.02, etc. Under normal operation of the flap structure, the temperature of the cylinder, the inlet duct, or the outlet duct rises at a certain rate. If the first temperature gradient is less than the reference gradient threshold, it indicates that the cylinder temperature (inlet duct temperature or outlet duct temperature) has not risen or has risen very slowly, indicating that the flap structure has stalled, thus confirming an abnormality in the flap structure. Conversely, if the first temperature gradient is greater than or equal to the reference gradient threshold, it indicates that the cylinder temperature (inlet duct temperature or outlet duct temperature) is rising normally, indicating that the flap structure has not stalled, confirming that the flap structure is not abnormal, and the flap structure is in a normal state.

[0048] When the flap structure is in normal condition, the first temperature change gradient is greater than or equal to the reference gradient threshold. In actual implementation, the first temperature change gradient will not be infinitely large, and it will generally not exceed 0.7 degrees Celsius per minute.

[0049] In some embodiments, the presence of an abnormality in the flap structure can be determined by the relationship between the temperature change gradient at the air inlet and the reference gradient threshold; the presence of an abnormality in the flap structure can also be determined by the relationship between the temperature change gradient at the air outlet and the reference gradient threshold. The determination method can refer to step S104.

[0050] In this embodiment, the detection method, through steps S101 to S104, includes: after receiving a start command in the form of a button, touch, or voice, the garment processing device responds to the start command by executing a garment processing program; then, a sensor can be used to obtain the first current temperature of the garment processing device's drum; if the first current temperature reaches a temperature threshold, a first temperature change gradient of the drum is determined every first preset time interval; finally, if the first temperature change gradient is less than a reference gradient threshold, it is determined that the flapper structure of the garment processing device is abnormal. Thus, by using the relationship between the first temperature change gradient of the drum and the reference gradient threshold, it is possible to promptly determine whether the flapper structure is abnormal; and when the first temperature change gradient is less than the reference gradient threshold, it is promptly determined that the flapper structure is abnormal, thereby avoiding the problem of long drying times due to flapper structure abnormalities, preventing damage to the compressor of the garment processing device, and ultimately extending the service life of the garment processing device.

[0051] In some embodiments, such as Figure 2 As shown, the "determining the first temperature change gradient of the cylinder" in step S103 above can be achieved through the following steps S1031 to S1035:

[0052] Step S1031: Obtain the second current temperature of the cylinder, start the timer, and obtain the timer duration.

[0053] Here, a second current temperature of the drum can be obtained through a temperature sensor. The garment handling equipment is also equipped with a timer. After obtaining the second current temperature, the timer can be started to keep track of the duration.

[0054] Step S1032: Determine whether the timing duration has reached the first preset duration.

[0055] Here, the size comparison method can be used to determine the relationship between the timing duration and the first preset duration. If the timing duration reaches the first preset duration, it indicates that the first preset duration has elapsed, and then proceed to step S1033; if the timing duration does not reach the first preset duration, that is, the timing duration is less than or equal to the first preset duration, it indicates that the first preset duration has not elapsed, and then proceed to step S1035.

[0056] Step S1033: Obtain the third current temperature of the cylinder.

[0057] Here, when the timing reaches the first preset duration, indicating that the first preset duration has elapsed, the third current temperature of the cylinder is obtained through the temperature sensor.

[0058] Step S1034: Determine the first temperature change gradient based on the first preset duration, the second current temperature, and the third current temperature.

[0059] Here, the temperature difference between the third current temperature and the second current temperature can be determined first, and then the quotient of the temperature difference and the first preset time can be determined as the first temperature change gradient.

[0060] Among them, the temperature difference refers to the temperature difference obtained by subtracting the second current temperature from the third current temperature, and the quotient is the quotient obtained by dividing the temperature difference by the first preset duration.

[0061] In some embodiments, after the first temperature change gradient is determined each time, the timer is reset to zero and restarted to prepare for determining the first temperature change gradient of the cylinder in the next time period, thereby realizing continuous monitoring of the temperature change gradient of the cylinder.

[0062] Step S1035: Continue timing.

[0063] Here, if the timing duration has not reached the first preset duration, that is, if the timing duration is less than or equal to the first preset duration, it indicates that the first preset duration has not been reached. Based on this, the timing continues to be recorded by the timer until the timing duration reaches the first preset duration.

[0064] In this embodiment, through steps S1031 to S1035, the second current temperature of the cylinder is first obtained, and a timer is started. Then, when the timer reaches a first preset duration, the third current temperature is obtained. Finally, the rate of temperature change is determined by the second current temperature, the third current temperature, and the first preset duration, i.e., the first temperature change gradient is determined. This allows for the rapid and accurate determination of the first temperature change gradient, thus providing support for subsequent anomaly detection.

[0065] In some embodiments, after step S104 above, "determining that the first temperature change gradient is less than a reference gradient threshold, and determining that the flap structure of the clothing processing equipment is abnormal," as follows: Figure 3 As shown, steps S105 to S120 can also be performed:

[0066] Step S105: Obtain the reference troubleshooting parameters corresponding to the motor of the clothing processing equipment.

[0067] Here, the reference obstacle removal parameters include the reference rotation speed, the first duration of forward rotation, and the second duration of reverse rotation.

[0068] In this embodiment of the application, the reference obstacle removal parameters corresponding to the motor can be obtained through the parameter acquisition command. The reference obstacle removal parameters can be the factory default value, the custom setting value, or the adjustment value based on the default value.

[0069] In actual implementation, the reference rotation speed of the reference obstacle removal parameter can be the maximum rotation speed of the clothing processing equipment, such as 3000 revolutions per minute. The first duration can be 14 seconds, 15 seconds, 16 seconds, etc., and the second duration can also be 14 seconds, 15 seconds, 16 seconds, etc. The first duration can be the same as the second duration, or the first duration can be different from the second duration.

[0070] Step S106: Adjust the motor's operating parameters to the reference obstacle removal parameters, control the motor to rotate forward at the reference speed for a first duration, and then rotate backward at the reference speed for a second duration.

[0071] When the garment processing equipment is normally executing the garment processing program, the motor operates according to the set speed, which is less than the maximum speed, and the duration of forward rotation is greater than the duration of reverse rotation.

[0072] In this embodiment, the motor's operating parameters are adjusted to reference obstacle removal parameters, so that the motor can be controlled to rotate forward at the reference speed for a first duration and then rotate backward at the reference speed for a second duration.

[0073] Taking the reference speed as the maximum speed, and the first and second durations being the same and both 15 seconds, as an example, the motor is controlled to rotate forward at the maximum speed for 15 seconds, and then the motor is controlled to rotate backward at the maximum speed for 15 seconds.

[0074] Step S107: Determine the second temperature gradient of the garment processing equipment.

[0075] Here, the second temperature change gradient is the temperature change gradient of the cylinder after the motor runs based on the reference obstacle removal parameters.

[0076] In this embodiment of the application, the implementation process of step S107 is similar to the implementation process of "determining the first temperature change gradient of the cylinder" in step S103 above. Therefore, the implementation process of step S107 can refer to the implementation process of "determining the first temperature change gradient of the cylinder" in step S103 above.

[0077] Step S108: Determine whether the second temperature change gradient is greater than the reference gradient threshold.

[0078] Here, the magnitude relationship between the second temperature change gradient and the reference gradient threshold can be determined by comparing their magnitudes. If the second temperature change gradient is greater than the reference gradient threshold, it indicates that the temperature is rising normally and the flap structure does not have a jamming problem, then proceed to step S109. If the second temperature change gradient is less than the reference gradient threshold, it indicates that the temperature is not rising or the temperature is rising very slowly, and the flap structure has a jamming problem, then proceed to step S114.

[0079] In some embodiments, if the second temperature change gradient is equal to the reference temperature threshold, it is assumed that the flap structure does not have a jamming problem, and the process proceeds to step S109.

[0080] Step S109: Confirm that the flap structure has returned to normal.

[0081] At this point, if the second temperature change gradient is greater than the reference gradient threshold, it indicates that the temperature is rising normally. If the flap structure does not have any jamming issues at this time, it is determined that the flap structure has returned to normal.

[0082] In some embodiments, the second temperature change gradient is equal to the reference gradient threshold, which also indicates that the flap structure does not have a jamming problem and that the flap structure has returned to normal.

[0083] Step S110: Control the garment processing equipment to continue executing the garment processing procedure.

[0084] Here, it has been determined that the flip-board structure has returned to normal, indicating that the abnormality has been eliminated. Based on this, the clothing processing equipment is controlled to continue executing the clothing processing procedure.

[0085] Step S111: Determine the third temperature change gradient of the cylinder at every second preset time interval.

[0086] Here, a third temperature change gradient for the cylinder is determined at second preset time intervals, where the second preset time interval is shorter than the first preset time interval. For example, the second preset time interval can be 50 seconds, 1 minute, 1.2 minutes, etc.

[0087] In this embodiment of the application, considering the instability that may occur during the operation of the garment processing equipment, after the flip-plate structure recovers from an abnormal state to a normal state, the abnormality detection of the flip-plate structure will be performed more frequently. That is, the third temperature change gradient of the drum will be determined at a shorter time interval, thereby improving the stability of the operation of the garment processing equipment.

[0088] Step S112: Determine whether the number of third temperature change gradients reaches the first threshold, and whether each third temperature change gradient is greater than the reference gradient threshold.

[0089] Here, the relationship between the number of obtained third temperature change gradients and the first threshold can be determined by comparing their magnitudes. The relationship between each third temperature change gradient and the reference gradient threshold can also be determined by comparing their magnitudes sequentially.

[0090] The threshold for the first count can be the factory default value or a custom setting value. For example, the threshold for the first count can be 3, 4, 5, etc.

[0091] If the number of third temperature change gradients reaches the first threshold, and each third temperature change gradient is greater than the reference gradient threshold, it indicates that the flap structure has been detected to have returned to normal operation multiple times. At this point, the flap structure is considered to be operating stably and normally, and the process proceeds to step S113. However, if the number of third temperature change gradients does not reach the first threshold, or if there is a target third temperature change gradient among the multiple third temperature change gradients that is less than the reference gradient threshold, the flap structure still cannot operate stably and normally, and the process proceeds to step S114.

[0092] Step S113: Continue to determine the first temperature change gradient of the cylinder at each first preset time interval.

[0093] At this point, if the number of third temperature change gradients reaches the first threshold and each third temperature change gradient is greater than the reference gradient threshold, it indicates that the flap structure has been detected to return to normal multiple times. At this point, it is considered that the flap structure has been operating stably and normally, and the frequency of detecting abnormalities is restored. That is, the first temperature change gradient of the cylinder is determined once every first preset time interval.

[0094] Step S114: Confirm that the flap structure still has anomalies.

[0095] If the number of third temperature change gradients does not reach the threshold of the first count, or if there is a target third temperature change gradient among the multiple third temperature change gradients that is less than the reference gradient threshold, then the flap structure still cannot operate stably and the anomaly has not been eliminated, thus confirming that the flap structure still has an anomaly.

[0096] Step S115: Obtain the number of times the reference troubleshooting parameters have been executed.

[0097] Here, the execution count of the reference obstacle removal parameter can be obtained through the count acquisition command, where the execution count represents the number of times the motor executes the reference obstacle removal parameter.

[0098] Step S116: Determine whether the number of executions has reached the threshold for the second time.

[0099] Here, the relationship between the number of executions and the second threshold can be determined by comparing the magnitudes. If the number of executions is less than the second threshold, it is considered that the number of executions has not yet reached the second threshold, indicating that the number of times the reference obstacle-clearing parameters have been executed has not yet reached the upper limit. Then, proceed to step S117, that is, continue to control the motor to run based on the reference obstacle-clearing parameters. If the number of executions is greater than or equal to the second threshold, it is considered that the number of executions has reached the second threshold, indicating that the number of times the reference obstacle-clearing parameters have been executed has reached the upper limit. Then, proceed to step S118.

[0100] In this embodiment of the application, the second number threshold is the upper limit of the number of executions. The second number threshold can be the factory default value or a custom setting value. For example, the second number threshold can be 3, 4, 5, etc.

[0101] Step S117: Continue to control the motor to run according to the reference speed, the first duration and the second duration, and increment the execution count by 1 to obtain the updated execution count.

[0102] At this point, if the number of executions is less than the second threshold, it is considered that the number of executions has not yet reached the second threshold, indicating that the number of times the reference troubleshooting parameters have been executed has not yet reached the upper limit. Therefore, the motor is controlled to continue to operate according to the reference speed, the first duration, and the second duration to eliminate the abnormality of the flap structure.

[0103] In this embodiment, the execution count is incremented by 1 each time the motor executes the reference obstacle removal parameters, and the updated execution count is obtained after the increment.

[0104] Step S118: Control the clothing processing equipment to stop operating.

[0105] At this point, if the number of executions is greater than or equal to the second threshold, it is considered that the number of executions has reached the second threshold, indicating that the maximum number of times the reference troubleshooting parameters have been executed has been reached, and the flap structure still exhibits abnormalities. To stop the damage in time, avoid other abnormal situations, or prevent dangerous accidents, the clothing processing equipment can be stopped by issuing a pause command.

[0106] Step S119: Generate an alarm message based on the detection results.

[0107] Here, if the detection result is abnormal, an alarm message indicating the abnormality can be generated. In actual implementation, this alarm message can be at least one of character information, sound information, and indicator light control information.

[0108] Step S120: Output an alarm message.

[0109] Here, if the alarm message includes character information, the alarm message can be output through the display screen of the garment processing equipment, for example, the fault code corresponding to the flipping abnormality; if the alarm message includes sound information, the alarm message can be output through the buzzer of the garment processing equipment; if the alarm message includes indicator light control information, the alarm message can be output through the indicator lights of the garment processing equipment.

[0110] In this embodiment, through steps S105 to S120, firstly, when an anomaly is determined in the flap structure, the anomaly can be eliminated based on reference troubleshooting parameters. If the anomaly is successfully eliminated using the reference troubleshooting parameters, it indicates that the flap structure has returned to normal, and the clothing processing equipment continues to execute the clothing processing program. If the anomaly cannot be eliminated using the reference troubleshooting parameters, the clothing processing equipment is suspended to avoid dangerous situations caused by the anomaly, thereby improving the safety performance of the clothing processing equipment. Secondly, after the clothing processing equipment recovers from an abnormal state to a normal state, the frequency of anomaly detection is increased to improve the stability of the clothing processing equipment. Anomaly detection is only performed at the normal frequency after it is determined that the clothing processing equipment is operating stably and normally. Thirdly, after the clothing processing equipment is suspended, an alarm message is generated and output to indicate the presence of an anomaly, achieving the purpose of reporting a repair, thereby improving the automation and intelligence level of the clothing processing equipment.

[0111] Based on the above embodiments, this application further provides a detection method, which includes the following four steps:

[0112] Step 1: Power on the device.

[0113] Here, the garment processing equipment can be turned on by starting the compressor.

[0114] Step two: Monitor the temperature in real time.

[0115] Here, after the compressor starts, a temperature sensor installed below the filter monitors the air duct temperature in real time to assist in determining the dryness of clothes. This temperature sensor can be a negative temperature coefficient thermistor.

[0116] Step 3: Determine the temperature gradient.

[0117] Here, we assume the temperature at time t1 is T1 and the temperature at time t2 is T2. Then, the rate of temperature change during the time interval from t1 to t2, i.e., the temperature gradient x = (T2 - T1) / (t2 - t1), is used to represent how fast the temperature rises.

[0118] In practice, the temperature rise curve of clothing processing equipment is relatively stable during operation, especially the sensor below the filter, which does not experience sudden temperature rises or falls, thus the temperature gradient x does not change drastically. However, if the flap structure gets stuck in a certain position with the back panel or back cover during the flipping process, failing to reach the corresponding side of the back cover, the overall airflow will decrease significantly. Because of the reduced airflow, the heat transfer efficiency of the compressor in the circulation system decreases, and the system temperature cannot rise as normally as during operation, causing the temperature gradient x to drop abruptly. Let's assume the minimum temperature gradient of the clothing processing equipment is A. When x < A, it is considered that the flap structure has become stuck.

[0119] Step 4: Anomaly detection.

[0120] If x > A, the drying process is normal; if x < A, the flap structure is malfunctioning. Emergency measures are needed to resolve the jamming issue.

[0121] To resolve the problem, a troubleshooting command was sent to the controller. Upon receiving the signal, the controller increased the motor speed to its maximum speed. The purpose of increasing the speed was to increase the wind force, thereby using the wind load to move the flap structure and remove the jam.

[0122] The motor operates as follows: it rotates clockwise for 15 seconds at its maximum speed, then counterclockwise for 15 seconds; this switching pattern repeats up to 3 times. Afterward, the motor returns to its normal speed and operates normally.

[0123] After troubleshooting, the flap structure still exhibits two states: normal rotation or abnormal rotation. Therefore, it is necessary to re-infer whether the flap is malfunctioning by detecting the magnitude of the temperature gradient x, i.e., repeating the above judgment logic: if x > A, the drying program is normal; if x < A, the flap is malfunctioning.

[0124] If the second assessment still indicates a fault, repeat the troubleshooting procedure by increasing the motor speed. This troubleshooting procedure can be repeated a maximum of three times.

[0125] If the normal value cannot be reached after three attempts, it indicates that the above emergency troubleshooting methods are ineffective. In this case, the machine should be stopped immediately, an error message should be displayed, and maintenance should be requested.

[0126] Thus, the detection method provided in this application embodiment can promptly detect any abnormalities in the flip-plate structure and automatically execute a troubleshooting procedure to eliminate the abnormality. This avoids prolonged drying times caused by the abnormality, prevents damage to the compressor of the garment processing equipment, and ultimately extends the service life of the equipment. If the abnormality cannot be eliminated after three troubleshooting procedures, the machine will be shut down for repair, improving the robustness and intelligence of the garment processing equipment.
