[0038] The present application will be further described by examples in conjunction with the accompanying drawings.
[0039] 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 in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.
[0040] The present application provides a control method of a laundry treating apparatus, which can be a clothes dryer or a washer-dryer with drying function. The laundry treating apparatus can include a tub for containing laundry, a heating device and a fan. The heating device and / or the fan can be arranged in a drying duct of the laundry treating apparatus or outside the drying duct. The fan is configured to circulate and introduce air flow into the drying duct, and the heating device is configured to heat the air flow in the drying duct. The heating device can be a heating pipe or a heat pump system. For example, for a direct exhaust or condensing washer-dryer, the heating device is a heating pipe, and for a heat pump washer-dryer, the heating device is a heat pump system. The present application does not limit the form of the heating device.
[0041] In the present application, a filter screen is arranged on the laundry treating apparatus, which can filter the air flow for drying the laundry to collect the lint and other impurities during the drying operation. For example, the filter screen can be arranged at the inlet of the drying duct and / or the outlet of the tub.
[0042] As shown in FIG. 1, the control method of the laundry treating apparatus according to an embodiment of the present application includes the following steps. Figure 1
[0043] Step 101: Obtain a first load value of the motor driving the tub to rotate in a first direction.
[0044] Step 102: Obtain a second load value of the motor driving the tub to rotate in a second direction.
[0045] Step 103: Determine whether the filter screen of the laundry treating apparatus is blocked based on the difference between the first load value and the second load value and a set load threshold.
[0046] It can be understood that the embodiments of the present application can determine whether the filter screen of the clothes processing device is blocked based on the first load value and the second load value of the motor, intelligently detect the blocking degree of the filter screen, and thus timely find that the filter screen is blocked, thereby improving the drying effect of the clothes processing device.
[0047] Exemplarily, the motor drives the drum and the fan of the clothes processing device at the same time, wherein the motor drives the fan to rotate when the motor drives the drum to rotate in the first direction, and the motor does not drive the fan to rotate when the motor drives the drum to rotate in the second direction. In some embodiments, the motor can drive the drum and the fan to rotate at the same time, and the motor driving the drum and the fan is the same motor. After the clothes processing device is started, the motor rotates forward to drive the drum to rotate in the first direction. At this time, the motor can drive the drum to rotate in the first direction through the first transmission mechanism and drive the fan to rotate through the second transmission mechanism. Therefore, the first load value of the motor obtained can be understood as the sum of the load of the clothes in the drum and the air volume load of the fan.
[0048] Exemplarily, the motor of the clothes processing device can be reversed to drive the drum to rotate in the second direction. At this time, the second transmission mechanism does not drive the fan, and thus the second load value of the motor obtained can be converted into the load of the clothes in the drum.
[0049] In the embodiments of the present application, the clothes processing device includes a motor driving the drum and the fan, wherein the motor drives the drum through a first transmission mechanism, and the motor drives the fan through a second transmission mechanism. Exemplarily, the first transmission mechanism can be a belt or a gear transmission mechanism. For example, the motor can drive the drum through a belt. When the motor rotates forward, the motor can drive the drum to rotate in the first direction. When the motor reverses, the motor can drive the drum to rotate in the second direction. The second transmission mechanism can be a reversing mechanism driving the fan when the motor rotates forward and not driving the fan when the motor reverses. For example, the second transmission mechanism arranged between the motor and the fan can include a driving wheel connected to the motor, a driven wheel connected to the fan, and a transmission device connecting the driving wheel and the driven wheel. The transmission device can perform a reversing action under the action of an external force such as electromagnetic force. When the motor rotates forward, the transmission device connects the driving wheel and the driven wheel, thereby driving the fan to rotate. When the motor reverses, the transmission device disconnects the driving wheel and the driven wheel, thereby not driving the fan to rotate.
[0050] In the embodiments of the present application, the first direction can be the main rotation direction of the drum during the drying process, that is, during the drying process, the drum can drive the clothes to rotate in the first direction, thereby accelerating the heat exchange efficiency between the clothes and the airflow and shortening the drying time; the second direction is the auxiliary rotation direction of the drum for stirring the clothes being dried, that is, the clothes in the drum can be stirred based on the rotation of the drum in the second direction, thereby effectively reducing the defects of uneven drying caused by the entanglement of the clothes in the drum. For example, the first direction is the clockwise direction, and the second direction is the counterclockwise direction, or the first direction is the counterclockwise direction, and the second direction is the clockwise direction.
[0051] Here, the difference between the first load value and the second load value can be understood as the airflow load of the fan, and thus, based on the difference and the set load threshold, it can be determined whether the filter screen of the clothes processing device is blocked.
[0052] The set load threshold can be determined based on test data, for example, the load values of the filter screen under different blockage degrees are collected respectively to determine the set load threshold, so that the blockage degree of the filter screen of the clothes processing device can be represented by the difference between the first load value and the second load value. Thus, based on the difference between the collected first load value and second load value and the set load threshold, it can be determined whether the filter screen of the clothes processing device is blocked, and the blockage degree of the filter screen can be intelligently detected, so that the blockage of the filter screen can be found in time, thereby improving the drying effect of the clothes processing device.
[0053] It can be understood that the first direction is the main rotation direction of the drum during the drying process, and the second direction is the auxiliary rotation direction of the drum for stirring the clothes being dried.
[0054] It should be noted that in the embodiments of the present application, the obtained first load value and second load value can correspond to the collection process of driving the drum to rotate in the first direction and the second direction respectively by the motor once; in addition, in order to improve the accuracy of data collection, the collection process of driving the drum to rotate in the first direction and the second direction respectively by the motor at least twice can also be provided.
[0055] For example, if the first load value and the second load value corresponding to the respective driving of the drum in the first direction and the second direction by the motor are obtained only once; accordingly, based on the difference between the first load value and the second load value and the set load threshold, it is determined whether the filter screen of the clothes processing device is blocked, comprising:
[0056] obtaining the difference between the first load value and the second load value;
[0057] generate a clogging level representing a clogging degree of the filter screen of the clothes processing device based on the threshold interval into which the difference value falls.
[0058] The clogging level includes at least two levels representing different clogging degrees.
[0059] It can be understood that, in the set load threshold, as the clogging degree becomes more and more serious, the value of the load threshold becomes smaller and smaller, that is, the clogging degree of the filter screen is negatively correlated with the air volume load.
[0060] In an application example, assuming that the load threshold is K, the set threshold interval is shown in Table 1:
[0061] Table 1
[0062] K value Clogging level K>=80 No clogging 60<=K<80 Slightly clogging 40<=K<60 Generally clogging K<25 Serious clogging
[0063] In this way, the clogging level of the filter screen can be determined based on the difference between the first load value collected when the motor rotates forward and the second load value collected when the motor rotates reversely and the above set threshold interval. If the difference value is 45, it is determined that the clogging level of the filter screen is general clogging.
[0064] In some embodiments, the first load value and the second load value corresponding to each of the times when the motor drives the drum to rotate in the first direction and the second direction are acquired at least twice. Correspondingly, determining whether the filter screen of the clothes processing device is clogged based on the difference between the first load value and the second load value and the set load threshold includes:
[0065] calculating a difference cumulative value or a difference average value based on the difference between the first load value and the second load value at least twice;
[0066] determining whether the filter screen of the clothes processing device is clogged based on the difference cumulative value or the difference average value and the set load threshold.
[0067] For example, determining whether the filter screen of the clothes processing device is clogged based on the difference cumulative value or the difference average value and the set load threshold includes:
[0068] generating a clogging level representing a clogging degree of the filter screen of the clothes processing device based on the threshold interval into which the difference value falls.
[0069] The clogging level includes at least two levels representing different clogging degrees.
[0070] In an application example, the clogging level includes two levels of no clogging and serious clogging. The determination of whether the filter screen of the clothes treatment device is clogged based on the difference cumulative value or the difference average value and the set load threshold value includes:
[0071] determining that the difference cumulative value or the difference average value is greater than or equal to the load threshold value, and determining that the filter screen is not clogged;
[0072] determining that the difference cumulative value or the difference average value is less than the load threshold value, and determining that the filter screen is seriously clogged.
[0073] It can be understood that for the difference values collected multiple times, the set load threshold value can be determined based on the test data of the difference cumulative value or the test data of the difference average value. If the set load threshold value is determined based on the test data of the difference cumulative value, the clothes treatment device will sum the differences between the first load values and the second load values collected multiple times when detecting the clogging of the filter screen, and generate a clogging level representing the clogging degree of the filter screen of the clothes treatment device based on the threshold interval into which the sum result falls. If the set load threshold value is determined based on the test data of the difference average value, the clothes treatment device will average the differences between the first load values and the second load values collected multiple times when detecting the clogging of the filter screen, and generate a clogging level representing the clogging degree of the filter screen of the clothes treatment device based on the threshold interval into which the average result falls. In this way, the accuracy of the filter screen clogging detection can be improved, and the detection error can be reduced.
[0074] In the embodiments of the present application, the first load value and the second load value can be values proportional to the clothes in the barrel. For example, the first load value and the second load value are the operating current value or the motor torque value of the motor.
[0075] In some embodiments, the method further includes:
[0076] determining that the clogging level of the filter screen falls within the set level standard, and controlling the clothes treatment device to run in a drying mode; or
[0077] determining that the clogging level of the filter screen does not fall within the set level standard, and outputting a filter screen clogging prompt information and / or controlling the clothes treatment device to automatically clean the filter screen.
[0078] It can be understood that the clothes treatment device of the embodiments of the present application can detect the clogging of the filter screen before the clothes are dried, and determine whether to continue the subsequent clothes drying based on the detection result of whether the filter screen is clogged, so as to ensure the reliable operation of the clothes drying.
[0079] In an application example, as Figure 2As shown, the control method of the laundry treating apparatus comprises:
[0080] Step 201, selecting a target program and starting the laundry treating apparatus.
[0081] Here, the user can select a target program and start the laundry treating apparatus based on the operation panel on the laundry treating apparatus or the remote communication manner, and the target program can be a drying program or a laundry treating program with drying function.
[0082] Step 202, performing filter clogging detection.
[0083] Here, the laundry treating apparatus can perform the filter clogging detection by running the filter clogging detection method of the present application, and obtain the clogging level of the current filter, which can be referred to the description of the present application in the following and Figure 3 .
[0084] Step 203, judging whether the clogging level is the set level standard, if not, executing step 204 and returning to step 202; if yes, executing step 205.
[0085] Here, the laundry treating apparatus judges whether the clogging level of the current filter is the set level standard, for example, assuming that the set level standard for running the laundry drying is “no clogging”, if the clogging level of the current filter is “no clogging”, step 205 can be executed, otherwise, step 204 needs to be executed and then return to step 202.
[0086] It can be understood that the set level standard can be reasonably adjusted based on the demand, for example, it can include “no clogging” and “slightly clogging”, so that the cleaning frequency of the filter can be reasonably adjusted, which is not limited by the present application.
[0087] Step 204, outputting filter clogging prompt information to prompt the user to clean the filter.
[0088] Here, the laundry treating apparatus can output the clogging level of the current filter based on the indicator light, display screen, voice playing and the like to prompt the user to clean the filter, in addition, for the laundry treating apparatus with automatic filter cleaning function, the filter cleaning program can be automatically run to automatically clean the filter, and then return to step 202 to detect the clogging level of the current filter again.
[0089] Step 205, running the target program.
[0090] Here, the clothes treatment apparatus determines that the clogging level of the current filter meets the set level standard, and thus determines that the clothes treatment apparatus can perform the target program to implement the clothes drying function. In this way, the reduction in the amount of air intake, the increase in drying time, and the increase in energy consumption of the apparatus caused by filter clogging during the drying operation can be effectively avoided, thereby ensuring the efficiency and quality of the clothes drying.
[0091] In an application example, as shown in Figure 3 The "filter clogging detection" specifically includes the following steps.
[0092] Step 301: Drive the drum to rotate in a first direction.
[0093] Here, after the clothes treatment apparatus starts the filter clogging detection, the motor drives the drum to rotate in the first direction. At this time, the motor also drives the fan to rotate through the second transmission mechanism.
[0094] Step 302: Obtain a first load value of the motor.
[0095] Here, the first load value of the motor can be obtained when the motor operates at a set speed, for example, the working current value or the motor torque value of the motor.
[0096] Step 303: Drive the drum to rotate in a second direction.
[0097] Here, the clothes treatment apparatus can control the motor to drive the drum to rotate in the second direction. At this time, the second transmission mechanism does not drive the fan.
[0098] Step 304: Obtain a second load value of the motor.
[0099] Here, the second load value of the motor can be obtained when the motor operates at a set speed, for example, the working current value or the motor torque value of the motor.
[0100] Step 305: Calculate the difference between the first load value and the second load value.
[0101] Step 306: After comparing the difference with a set load threshold, a clogging degree is generated.
[0102] As shown in Table 1 above, the clogging degree of the current filter can be determined based on the threshold interval in which the calculated difference falls.
[0103] To implement the method of the present application, the present application also provides a control device of a clothes treatment apparatus, which corresponds to the above-mentioned control method of the clothes treatment apparatus.
