[0022] An exhaust blockage detection request is obtained, and based on the exhaust blockage detection request, the control of heating the laundry processing device to a preset temperature is executed, and the heating device is turned off at time t1 when the heating reaches the preset temperature.

[0023] In some embodiments, before controlling the laundry treatment device to heat to a preset temperature and turning off the heating device at time t1 when the laundry treatment device is heated to the preset temperature, the method includes: starting a laundry treatment program.

In the prior art, since the temperature in the barrel is high when the heating device is working, and the temperature of the exhaust pipe is relatively low compared to that in the barrel, it is greatly affected by the high temperature in the barrel. The high temperature environment in the barrel is likely to cause the temperature of the exhaust pipe to change, thereby affecting the actual temperature of the exhaust pipe. There may be a situation where the exhaust is not blocked but the temperature is still high, resulting in an inability to accurately determine whether the exhaust is blocked. The embodiment of the present disclosure controls the clothing processing equipment to heat to the preset temperature and then turns off the heating device, obtains the recovery time to restore to the preset temperature after turning off the heating device, eliminates the high temperature interference factor when the heating device is running, and ensures the accuracy of detection.

[0040] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. In some embodiments, the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0042] Clothes can be dried by a clothes treatment device with a drying function. For example, the heated hot air is sent to the clothes treatment device through the air duct and placed in the clothes treatment chamber. The hot air contacts the wet clothes, thereby drying the clothes and reducing the water content of the clothes. The hot and humid air passes through the filter and enters the air duct for discharge. Due to errors that may occur during the installation of the exhaust pipe, the exhaust pipe may be installed incorrectly, causing exhaust blockage and affecting the discharge of hot air; or the clothes treatment device is used for too long, and hair scraps will be generated during the drying process, which will adhere to the filter net after filtering. If it is not cleaned for a long time, the filter net will be covered with a large area, resulting in the hot air being unable to pass through the filter net, causing exhaust blockage. Or the exhaust pipe of the clothes treatment device is too long or bent, causing exhaust blockage. Exhaust blockage will cause the air volume to decrease during drying, and the hot air cannot circulate normally to cool down, causing the clothes treatment device to continue to heat up, which not only affects the drying effect, but also may cause damage to the device itself.

[0043] In view of the above-mentioned defects of the prior art, an embodiment of the present disclosure provides a control method for a clothing processing device. The method can be executed by a control device of the clothing processing device provided by the embodiment of the present disclosure, and the control device of the clothing processing device can be implemented in software and / or hardware. The control method of the clothing processing device provided by the embodiment of the present disclosure can be applicable to clothing processing devices with direct-discharge drying function or other types of clothing processing devices with drying function. The embodiment of the present disclosure does not limit the type of drying principle, for example, direct-discharge, condensing or heat pump types are all applicable. Figure 1 A flow chart of a control method for a clothes processing device provided by an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the control method of the clothes processing device includes S110 to S130:

[0044] S110, controlling the clothes processing device to heat to a preset temperature, and turning off the heating device at time t1 when the clothes processing device is heated to the preset temperature.

[0045] During the operation of the clothing treatment device, the heating device is in the start-up state. At this time, the clothing treatment device can be controlled to heat to a preset temperature, and the heating device is turned off at the time t1 when the preset temperature is reached. For example, the preset temperature is set to 48°C, and the time when the heating device heats to 48°C is t1, and the heating device is turned off at this time. The time when the preset temperature is heated and the time when the heating device is turned off are the same time, recorded as t1.

[0046] S120, obtaining the time t2 when the temperature is restored to the preset temperature, and determining the time from the time t1 to the time t2 as the restoration time.

[0047] After the heating device is turned off, the temperature of the clothes processing device will not stop increasing immediately. The residual heat will cause the temperature to continue to rise for a period of time. When the temperature rises to a certain level, it will drop and return to the preset temperature. The time when the clothes processing device returns to the preset temperature is recorded as t2, and the time from time t1 to time t2 is determined as the recovery time (the temperature rises from the preset temperature and then drops back to the preset temperature). Exemplarily, the preset temperature is set to 48°C. After time t1, the temperature will continue to rise. After the temperature rises for a period of time, it will drop. The time when it drops back to the preset temperature of 48°C is recorded as t2, and the time from time t1 (the first time the preset temperature of 48°C is reached) to time t2 (the preset temperature of 48°C is reached again) is the recovery time.

[0048] S130: In response to the recovery time being greater than the blockage threshold time, determining that exhaust of the clothes processing device is blocked.

[0049] Based on the above steps, the obtained recovery time is compared with the blocking threshold time. If the recovery time is greater than the blocking threshold time, it is determined that the clothes processing device has exhaust blockage. The blocking threshold time may be, for example, a threshold time at which the exhaust pipe of the clothes processing device is blocked as determined by historical data. If the recovery time is greater than the blocking threshold time, it means that the recovery time is long, and the exhaust pipe of the clothes processing device is blocked, resulting in slow air circulation and slow temperature reduction. Therefore, it can be determined that the clothes processing device has exhaust blockage.

[0050] In the control method of the clothing processing device provided by the embodiment of the present disclosure, the clothing processing device is controlled to heat to a preset temperature, and the heating device is turned off at the moment t1 when the preset temperature is reached. After the heating device is turned off, the temperature will continue to rise for a period of time and then fall back until it falls back to the preset temperature. The moment t2 when the preset temperature is reached again is recorded. The time required from the moment t1 when the temperature is heated to the preset temperature to the moment t2 when the temperature is restored to the preset temperature again after the heating device is turned off is the recovery time. The embodiment of the present disclosure compares the recovery time with the blockage threshold time. If the recovery time is greater than the blockage threshold time, it means that the exhaust of the clothing processing device may be blocked, resulting in a slow cooling speed, that is, the recovery time is long. The embodiment of the present disclosure determines the exhaust condition of the clothing processing device through the relationship between the recovery time of the temperature of the clothing processing device and the blockage threshold time, detects the problem of exhaust blockage in time, improves the safety of the clothing processing device, and provides users with a good user experience.

[0051] The prior art generally determines whether the exhaust is blocked by obtaining the time required for the temperature change during the operation of the heating device of the clothing processing equipment. Compared with the prior art, the embodiment of the present disclosure turns off the heating device when the clothing processing equipment reaches the preset temperature, obtains the time required to restore to the preset temperature again (recovery time), and determines whether the exhaust is blocked by comparing the recovery time with the blockage threshold time. Since the heat generated by the exhaust heat dissipation of the exhaust duct is much smaller than the heat generated by the heating device, in the prior art, since the heating device is always in working state, the heating state of the heating device will cause great interference to the judgment of the speed of the exhaust heat dissipation of the exhaust duct. However, the embodiment of the present disclosure judges the speed of the exhaust heat dissipation by using the preheating generated by the heating device in the exhaust duct after turning off the heating device. Since there is no influence of the heat generated by the heating device, the high temperature interference factor when the heating device is running is eliminated, so the accuracy of the exhaust blockage detection result can be improved.

[0052] Optionally, a temperature sensor may be provided near the filter of the clothing processing device (for example, at the air duct in front of the filter) to detect the temperature, and the heating device may be turned off at time t1 when the temperature reaches a preset temperature.

[0053] In some embodiments, before obtaining the time t2 when the temperature is restored to the preset temperature and determining the time from the time t1 to the time t2 as the restoration time, the method further includes:

[0054] It is determined that the time after the heating device is turned off is greater than a preset time, and it is determined that the exhaust of the clothes processing device is blocked.

[0055] In the disclosed embodiment, when the clothes treatment device is controlled to heat to a preset temperature, and the heating device is turned off at the time t1 when the clothes treatment device is heated to the preset temperature, the temperature of the clothes treatment device will drop, and at the same time, the time length is counted (starting from the time when the heating device is turned off). Before obtaining the recovery to the preset temperature, if the counted time length is greater than the preset time length, it indicates that the temperature in the current clothes treatment device is recovering slowly and the user has been waiting for too long. In order to improve the detection efficiency and reduce the user's waiting time, it is not necessary to continue waiting for the temperature to recover to the preset temperature, and determine that the clothes treatment device exhaust is blocked. For example, the preset temperature is set to 48°C, the preset time length is set to X, and the time when the heating device is heated to 48°C is t1. At this time, the heating device is turned off and the time length is counted. If the counted time length is greater than the preset time length X before the temperature drops and recovers to the preset temperature of 48°C, it is not necessary to continue waiting for the temperature to recover to the preset temperature of 48°C. It can be considered that the waiting time is long and the temperature recovery is too slow, and it is determined that the clothes treatment device exhaust is blocked, and the time for the user to verify whether it is blocked can be reduced.

[0056] In some embodiments, in response to the recovery time being greater than the blockage threshold time, determining that the exhaust of the laundry treatment device is blocked includes:

[0057] S310: Acquire the current ambient temperature, and determine the blocking threshold time corresponding to the current ambient temperature according to the corresponding relationship between the ambient temperature and the blocking threshold time.

[0058] Under different ambient temperatures, the blockage threshold time corresponding to the exhaust of the clothes processing device has certain differences. The blockage threshold time can be considered as the critical time between exhaust blockage and unblockage. For example, the blockage threshold time can be calculated by the exhaust blockage time and the exhaust unblockage time under the same ambient temperature.

[0059] The corresponding relationship between the ambient temperature and the congestion threshold time can be learned based on the congestion threshold time of the historical ambient temperature. After obtaining the current ambient temperature, the congestion threshold time corresponding to the current ambient temperature can be determined based on the corresponding relationship between the ambient temperature and the congestion threshold time.

[0060] S320: In response to the recovery time being greater than the blockage threshold time corresponding to the current ambient temperature, determining that the exhaust of the clothes processing device is blocked.

[0061] Based on the above steps, the blocking threshold time corresponding to the current ambient temperature and the actual recovery time are obtained.

[0062] Since the blocking threshold time is the time required for the exhaust duct of the clothing processing equipment to recover to the preset temperature when it is at the dividing point between blocking and unblocking in the historical data, the recovery time is the duration from time t1 to time t2 at the current ambient temperature. The blocking threshold time corresponding to the current ambient temperature refers to the theoretical blocking threshold time determined by searching based on the correspondence between the ambient temperature and the blocking threshold time. If the recovery time corresponding to the detected current ambient temperature is greater than the blocking threshold time corresponding to the current ambient temperature, it means that the recovery time is long, the exhaust duct is blocked, resulting in slower air circulation and slower temperature reduction, so it can be determined that the clothing processing equipment has exhaust blockage. After determining the corresponding blocking threshold time in combination with the current ambient temperature and comparing it with the recovery time, the accuracy of the detection data can be improved and external interference factors can be avoided.

[0063] In some embodiments, determining the blocking threshold time corresponding to the current ambient temperature according to the corresponding relationship between the ambient temperature and the blocking threshold time includes:

[0064] S311 . According to the historical ambient temperature and the corresponding congestion threshold time, a curve of ambient temperature and congestion threshold time is determined by fitting.

[0065] S312: Determine the congestion threshold time corresponding to the current ambient temperature in the ambient temperature and congestion threshold time curve as the congestion threshold time corresponding to the current ambient temperature.

[0066] The problem of exhaust blockage may occur in the use of clothing processing equipment. Therefore, the corresponding blockage threshold time of the clothing processing equipment under the historical ambient temperature can be obtained, and the corresponding relationship between the ambient temperature and the blockage threshold time can be determined by referring to the historical data, and the ambient temperature and the blockage threshold time curve can be determined by fitting. In combination with the above curve, if it is necessary to determine whether the current clothing processing equipment is blocked, the blockage threshold time corresponding to the current ambient temperature can be found according to the current ambient temperature obtained, and the blockage threshold time can be determined as the blockage threshold time corresponding to the current ambient temperature by referring to the fitted ambient temperature and blockage threshold time curve.

[0067] Exemplarily, the fitting can be performed in the following way, Figure 2 A schematic diagram of distinguishing congestion curves provided in an embodiment of the present disclosure, such as Figure 2 As shown, three historical ambient temperatures are provided, namely 2°C, 23°C and 37°C. When the ambient temperature is 2°C, the clothes processing device is controlled to heat to the preset temperature when the exhaust is not blocked, and the heating device is turned off at the moment t1 when the clothes processing device is heated to the preset temperature, and the time required to recover to the preset temperature at the moment t2 from the moment t1 to the moment t2 is 16 seconds. In the case of exhaust blockage, the clothes processing device is controlled to heat to the preset temperature, and the heating device is turned off at the moment t1 when the clothes processing device is heated to the preset temperature, and the time required to recover to the preset temperature at the moment t2 from the moment t1 to the moment t2 is 44 seconds. The blockage threshold time corresponding to the ambient temperature of 2°C can be determined as 30 seconds, that is, the average value of the recovery time corresponding to the exhaust blockage and the recovery time corresponding to the exhaust not being blocked when the ambient temperature is 2°C.

[0068] When the ambient temperature is 23°C, the clothes processing device is controlled to heat to the preset temperature when the exhaust is not blocked, and the heating device is turned off at the time t1 when the clothes processing device is heated to the preset temperature, and the time to restore to the preset temperature at the time t2 is 30 seconds from the time t1 to the time t2. When the exhaust is blocked, the clothes processing device is controlled to heat to the preset temperature, and the heating device is turned off at the time t1 when the clothes processing device is heated to the preset temperature, and the time to restore to the preset temperature at the time t2 is 93 seconds from the time t1 to the time t2. The blockage threshold time corresponding to the ambient temperature of 23°C can be determined to be 61.5 seconds, that is, the average of the recovery time corresponding to the exhaust blockage and the recovery time corresponding to the exhaust unblockage when the ambient temperature is 23°C.

[0069] When the ambient temperature is 37°C, the clothes processing device is controlled to heat to the preset temperature when the exhaust is not blocked, and the heating device is turned off at the time t1 when the clothes processing device is heated to the preset temperature, and the time required to recover to the preset temperature at the time t2 is 65 seconds from the time t1 to the time t2. When the exhaust is blocked, the clothes processing device is controlled to heat to the preset temperature, and the heating device is turned off at the time t1 when the clothes processing device is heated to the preset temperature, and the time required to recover to the preset temperature at the time t2 is 224 seconds from the time t1 to the time t2. The blockage threshold time corresponding to the ambient temperature of 37°C can be determined as 144.5 seconds, that is, the average of the recovery time corresponding to the exhaust blockage and the recovery time corresponding to the exhaust unblockage when the ambient temperature is 37°C.

[0070] Therefore, by referring to the congestion threshold time corresponding to the above historical ambient temperature, a curve of ambient temperature and congestion threshold time can be fitted to obtain the congestion threshold time corresponding to the current ambient temperature, and then the congestion threshold time corresponding to the current ambient temperature can be determined.

[0071] Among them, the congestion threshold time can be obtained through actual detection, and can also be calculated by the recovery time when congested and the recovery time when not congested. The embodiments of the present disclosure do not limit this. At the same time, the embodiments of the present disclosure do not limit the type of the determined ambient temperature and congestion threshold time curve obtained by fitting. The linear curve in the above embodiment is only used as an example.

[0072] In some embodiments, determining the blocking threshold time corresponding to the current ambient temperature according to the corresponding relationship between the ambient temperature and the blocking threshold time includes:

[0073] According to the historical ambient temperatures corresponding to the two end points of the interval where the current ambient temperature is located and the congestion threshold times corresponding to the historical ambient temperatures, a linear interpolation method is used to determine the congestion threshold time corresponding to the current ambient temperature.

[0074] In the embodiments of the present disclosure, continue to refer to Figure 2 , obtain the historical ambient temperatures corresponding to the two end points of the current ambient temperature interval, and the congestion threshold time corresponding to the historical ambient temperatures. When it is necessary to determine the congestion threshold time corresponding to the required ambient temperature, the linear interpolation method can be used to determine the corresponding congestion threshold time. Figure 2 Three historical ambient temperatures are provided, namely 2°C, 23°C and 37°C.

[0075] Among them, the recovery time curve of ambient temperature and unblocked state includes three data points, namely (2, 16), (23, 30) and (37, 65). The recovery time curve of ambient temperature and unblocked state can be fitted based on the three data points. According to the two data points (2, 16) and (23, 30), the slope between the two points can be (30-16) / (23-2)≈0.67. According to the two data points (23, 30) and (37, 65), the slope between the two points can be (65-30) / (37-23)≈2.5.

[0076] The curve of ambient temperature and recovery time during blockage includes three data points, namely (2, 44), (23, 93) and (37, 224). The curve of ambient temperature and recovery time during blockage can be fitted based on the three data points. Based on the two data points (2, 44) and (23, 93), the slope between the two points is (93-44) / (23-2)≈2.33. Based on the two data points (23, 93) and (37, 224), the slope between the two points is (224-93) / (37-23)≈9.36.

[0077] For example, given that the current ambient temperature is 10°C, the congestion threshold time can be calculated by linear interpolation. It can be seen that the current ambient temperature of 10°C is between 2°C and 23°C. The slope of the data points (2, 16) and (23, 30) in the curve of ambient temperature and recovery time when not congested is (30-16) / (23-2)≈0.67. It can be calculated that the recovery time when the current ambient temperature of 10°C is not congested is 16+(10-2)*0.67≈21.3. At the same time, the slope of the data points (2, 44) and (23, 93) in the curve of recovery time when ambient temperature is congested is (93-44) / (23-2)≈2.33. It can be calculated that the recovery time when the current ambient temperature of 10°C is congested is 44+(10-2)*2.33≈62.64. The weighted average of the recovery time when not blocked and the recovery time when blocked is 42, that is, when the ambient temperature is 10°C, the corresponding blocking threshold time is 42 seconds.

[0078] Optionally, since the blockage threshold time is the average of the recovery time corresponding to exhaust blockage and the recovery time corresponding to exhaust non-blockage, the ambient temperature and blockage threshold time curve can be determined, and then the blockage threshold time corresponding to the current ambient temperature can be directly determined based on the ambient temperature and blockage threshold time curve.

[0079] For example, when the ambient temperature is 2°C, the corresponding congestion threshold time is 30 seconds, when the ambient temperature is 23°C, the corresponding congestion threshold time is 61.5 seconds, and when the ambient temperature is 37°C, the corresponding congestion threshold time is 144.5 seconds, that is, three data points (2, 30), (23, 61.5), and (37, 144.5) of the ambient temperature and congestion threshold time curve can be obtained. For example, the current ambient temperature is 10°C, and the congestion threshold time can be calculated by linear interpolation. 10°C is located in the interval (2°C, 23°C). The congestion threshold time corresponding to the current ambient temperature can be determined by linear interpolation based on the historical ambient temperatures corresponding to the two end points of the interval (2°C, 23°C) and the congestion threshold time corresponding to the historical ambient temperatures, that is, the congestion threshold time corresponding to the current ambient temperature of 10°C is 30+(10-2)*((61.5-30) / (23-2))=42.

[0080] In some embodiments, controlling the laundry processing device to heat to a preset temperature and turning off the heating device at time t1 when the laundry processing device is heated to the preset temperature includes:

[0081] The clothes treating device is controlled to heat to a preset temperature in an empty load state, and the heating device is turned off at time t1 when the clothes treating device is heated to the preset temperature.

[0082] When obtaining the recovery time of the clothes processing device, the clothes processing device is controlled to heat in a no-load state, and the heating device is turned off at the time t1 when the clothes processing device is heated to a preset temperature. Heating the clothes processing device in a no-load state can ensure the accuracy of the statistical recovery time and avoid abnormal detection results caused by different moisture contents in the loads in the clothes processing device.

[0083] In some embodiments, before controlling the laundry processing device to heat to a preset temperature and turning off the heating device at time t1 when the laundry processing device is heated to the preset temperature, the method includes:

[0084] An exhaust blockage detection request is obtained, and based on the exhaust blockage detection request, the laundry processing device is controlled to heat to a preset temperature, and the heating device is turned off at time t1 when the heating reaches the preset temperature.

[0085] Before controlling the clothes processing device to heat to a preset temperature, it is necessary to obtain an exhaust blockage detection request. When the clothes processing device receives the exhaust blockage detection request, it will execute the operation of obtaining the clothes processing device to heat to a preset temperature, and turn off the heating device at the time t1 when the clothes processing device is heated to the preset temperature. When obtaining the exhaust blockage detection request, a request button can be set on the clothes processing device, and when there is a need for exhaust blockage detection, the request button can be activated, or an exhaust blockage detection request can be sent to the clothes processing device through a remote control system. After obtaining the exhaust blockage detection request, the operation of controlling the clothes processing device to heat to a preset temperature and the like can be executed, and there is no need to judge whether the exhaust is blocked in real time, which can reduce the running power consumption of the device.

[0086] In some embodiments, before controlling the clothes treating device to heat to a preset temperature and turning off the heating device at time t1 when the clothes treating device is heated to the preset temperature, the method includes: starting a clothes treating program.

[0087] In the embodiment of the present disclosure, after starting the clothes treatment program, the clothes treatment device first controls the clothes treatment device to heat to a preset temperature, and turns off the heating device at the time t1 when the clothes treatment device is heated to the preset temperature, and obtains the time t2 when the clothes treatment device is restored to the preset temperature, thereby obtaining the restoration time, and then comparing it with the blocking threshold time to determine whether the clothes treatment device is blocked. After starting the clothes treatment program, the embodiment of the present disclosure first detects whether the exhaust of the clothes treatment device is blocked, which can avoid the problem of poor drying effect and equipment damage caused by running the clothes treatment program for clothes treatment when the exhaust of the clothes treatment device is blocked.

[0088] Optionally, in response to the recovery time being less than or equal to the jam threshold time, a laundry treatment operation is performed.

[0089] If the recovery time is compared with the blockage threshold time and it is found that the recovery time is less than or equal to the blockage threshold time, it can be understood that the exhaust of the clothing processing equipment is relatively smooth and there is no blockage. Therefore, the clothing processing operation corresponding to the start of the clothing processing program can be executed.

[0090] In some embodiments, after determining that the clothes processing equipment exhaust is blocked, the method further includes:

[0091] Control the clothes processing device to generate prompt information and / or send prompt information to the mobile terminal.

[0092] If it is determined that the exhaust of the clothing processing equipment is blocked, the clothing processing equipment needs to be handled in time. The clothing processing equipment can be controlled to generate prompt information, such as a sound prompt, to remind the user that the exhaust of the clothing processing equipment is blocked and needs to be handled in time, or a prompt can be given through the display screen of the clothing processing equipment, etc.

[0093] A prompt message may also be sent to the mobile terminal. In order to prevent the user from being away from the clothing treatment device, a prompt message may be sent to the user's mobile terminal to remind the user that the exhaust of the current clothing treatment device is blocked. If it is not handled in time, the drying effect will be affected and the clothing treatment device may be damaged. For example, a wireless communication module, such as a Bluetooth module or a WiFi module, is set in the clothing treatment device, and a prompt is sent to the user's mobile phone through the wireless communication module. The user may not be in the room, but the mobile phone is usually around, so the user can check the prompt in time.

[0094] For example, Figure 3 This is a structural block diagram of a control device for a clothes processing device provided by an embodiment of the present disclosure, and the control device for the clothes processing device can be integrated in the clothes processing device. Figure 3 As shown, the control device of the clothes processing equipment includes: a control module 31, a recovery time determination module 32 and an exhaust blockage determination module 33.

[0095] The control module 31 is used to control the clothes processing device to heat to a preset temperature, and turn off the heating device at the time t1 when the clothes processing device is heated to the preset temperature. The recovery time determination module 32 is used to obtain the time t2 when the clothes processing device is restored to the preset temperature, and determine the time from time t1 to time t2 as the recovery time.
