[0002] When using clothes handling equipment such as a clothes dryer or a washer-dryer to dry a load that needs to be dried, users have a need to know the drying time in real time. To meet the above needs, the relevant technology proposes to use humidity sensors and temperature sensors in the clothes handling equipment to detect temperature and humidity in the initial stage of drying, determine the load of the load to be dried based on the temperature and humidity detection signal mapping, and then determine a relatively accurate remaining drying time based on the load of the load to be dried and display it.

[0003] However, the aforementioned method of determining the remaining drying time using temperature and humidity detection signals requires the clothing processing equipment to start the drying operation for a long time, so that the temperature of the load to be dried and the air humidity of the air in the clothing processing barrel of the clothing processing equipment have changed significantly, and then only after obtaining significant temperature signals and air humidity signals can the remaining drying time be determined more accurately, resulting in a poor user experience.

[0044] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0045] The term "including" and its variations used in this document are open inclusions, that is, "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions of other terms will be given in the description below. It should be noted that the concepts of "first", "second", etc. mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the processes performed by these devices, modules or units.

[0046] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0047] In order to solve the problem that the existing method of using temperature and humidity detection takes a long time to determine the remaining drying time, the embodiment of the present disclosure provides a new control method for a clothing processing device. The control method for a clothing processing device provided by the embodiment of the present disclosure is based on a new type of detection signal, which can achieve relatively fast determination of the remaining drying time for the load to be dried.

[0048] Since the implementation of the control method of the clothing processing device provided in the embodiment of the present disclosure is based on the specific hardware structure of the clothing processing device, before analyzing the control method of the clothing processing device provided in the embodiment of the present disclosure, the specific hardware structure of the clothing processing device in the embodiment of the present disclosure is first analyzed.

[0049] The clothes processing device (i.e., clothes dryer or washer-dryer) in the disclosed embodiment includes not only the components of the existing clothes processing device but also a contact sensor. When the load to be dried contacts the contact sensor, the contact sensor generates a trigger signal and sends the trigger signal to the controller of the clothes processing device. The controller of the clothes processing device determines the load amount of the load to be dried according to the accumulated triggering time of the trigger signal, and determines the remaining drying time of the load to be dried according to the load amount.

[0050] In practical applications, the contact sensor can be various types of sensors.

[0051] In a specific application, the contact sensor can be a conductivity sensor. When a load still having a large water content contacts the two conductive electrodes of the conductivity sensor at the same time, the conductivity sensor can generate a conductivity signal, and the conductivity signal is used as the aforementioned contact signal. It should be noted that in the embodiment of the present disclosure, within a certain detection cycle, if the conductivity sensor is triggered within a detection cycle, that is, a current loop is formed between its two conductive electrodes to realize conductivity detection, then the time of the corresponding cycle is used as the trigger cycle of the load conductivity contact, which is used to accumulate and form a cumulative trigger duration. In some applications, the conductivity sensor simultaneously measures the conductivity of the load to be dried, detects the conductivity within a detection cycle, and generates a corresponding duty cycle signal based on the conductivity. The high potential ratio (or duration) in this duty cycle signal cannot be used to calculate the cumulative trigger duration.

[0052] In another specific application, the contact sensor may be a pressure sensor. When the load to be dried contacts the pressure sensor, the pressure sensor senses the trigger pressure and generates a pressure detection signal. The pressure detection signal is used as a contact signal.

[0053] In order to reasonably estimate the remaining drying time of the load to be dried using the detection signal generated by the contact sensor, the contact sensor needs to be installed at a specific position of the laundry processing device. In some specific applications, the contact sensor is arranged at a position near the front wall of the laundry processing tub of the laundry processing device.

[0054] The control method of the laundry processing device provided by the embodiment of the present disclosure is analyzed as follows. It should be noted that the control method of the laundry processing device provided by the embodiment of the present disclosure is executed by a controller of the laundry processing device.

[0055] Figure 1 1 is a flow chart of a control method for a clothes processing device provided by an embodiment of the present disclosure. Figure 1 As shown, the control method of the clothing processing device provided in the embodiment of the present disclosure includes S110-S120.

[0056] S110: Determine to start the drying operation of the load to be dried, and start counting the cumulative triggering time of the receiving sensor according to the received triggering signal.

[0057] In the embodiment of the present disclosure, after receiving the drying start instruction, the controller controls the actuator of the clothing processing device to operate so as to start the drying operation of the load to be dried.

[0058] The operation of the actuator for controlling the clothing processing equipment includes: (1) controlling the rotation of the clothing processing drum of the clothing processing equipment to realize the tumbling of the load to be dried in the clothing processing drum; (2) controlling the operation of the heating device of the clothing processing equipment to generate heat energy for heating the load to be dried; and (3) driving the fan to rotate to form a drying airflow, so that the heat energy generated by the operation of the heating device is transferred to the drying airflow, and then transferred by the drying airflow to the load to be dried in the clothing processing drum.

[0059] In addition to controlling the aforementioned actuators of the laundry processing device to operate, the controller also controls the contact sensor to start up and starts to receive a contact signal generated by the contact sensor.

[0060] As analyzed above, the contact signal is a signal generated by the contact sensor when the load to be dried contacts the contact sensor. In a specific implementation, since the load to be dried rolls under the drive of the clothes treatment tub, each part of the load to be dried may randomly contact the contact sensor during the rolling process, triggering the contact sensor to generate a contact signal.

[0061] It is known from empirical reasoning and actual tests that the greater the load of the load to be dried in the clothes treatment barrel, the greater the spread volume of the load to be dried in the clothes treatment barrel, and the greater the probability that the load to be dried contacts the contact sensor and triggers the contact sensor to generate a contact signal. Correspondingly, the greater the probability that the contact sensor generates a contact signal, the longer the time for the contact sensor to generate the contact signal during the drying operation, making the controller accumulate the trigger time according to the trigger signal statistics. In other words, the accumulated trigger time is positively correlated with the load of the load to be dried.

[0062] S120: When the running time of the drying operation reaches a first time, determining a first drying time according to the accumulated triggering time, and determining a first remaining drying time according to the first drying time and the running drying time of the clothes processing device.

[0063] In the embodiment of the present disclosure, when the drying operation of the load to be dried is started, the controller starts to time the running time of the drying operation.

[0064] When the running time of the drying operation reaches the first time length, the controller may stop receiving the trigger signal and stop timing the accumulated trigger time length, so that the accumulated trigger time length does not change any more.

[0065] The aforementioned first duration is a pre-set, shorter timing duration. In a specific embodiment, the first duration can be set to any duration between 1 and 10 minutes. It should be noted that although the first duration is a shorter timing duration, it cannot be too short to avoid the problem that the cumulative trigger duration obtained by statistics within an overly short duration is not representative.

[0066] After determining the cumulative triggering time, the controller can then determine a first drying time according to the cumulative triggering time. The first drying time is an estimated time that represents the time required for the drying operation.

[0067] In the disclosed embodiment, the first drying time is positively correlated with the cumulative triggering time. That is to say, the longer the cumulative triggering time is, the longer the corresponding first drying time is. How to determine the first drying time according to the cumulative triggering time will be analyzed in detail later. Here, it is only necessary to determine the first drying time that is positively correlated with the cumulative triggering time.

[0068] Here we analyze the rationality of the positive correlation between the first drying time and the cumulative trigger time. As stated above, the cumulative trigger signal is positively correlated with the load amount of the load to be dried. The greater the load amount of the load to be dried, the longer it takes to dry the load. In other words, the drying time of the load to be dried is positively correlated with its load amount. Combining the above two positive correlations, it can be determined that it is reasonable for the first drying time to be positively correlated with the cumulative trigger time.

[0069] When determining the first drying time, the running drying time of the clothes processing device can also be determined. In a specific implementation, the controller subtracts the running drying time from the first drying time to obtain an estimated first remaining drying time.

[0070] After determining the first remaining drying time, the controller controls the display device in the clothes processing apparatus to display a countdown starting from the first remaining drying time.

[0071] The control method of the clothing processing device provided by the embodiment of the present disclosure, after starting the drying operation of the load to be dried, counts the cumulative triggering time of the contact sensor triggered by the load to be dried according to the trigger signal generated by the contact sensor, and determines the first drying time according to the cumulative triggering time when the running time of the drying operation reaches a first time, and then determines the first remaining drying time according to the first drying time and the running drying time.

[0072] As analyzed above, after the clothes processing device is started for a short first time, the accumulated triggering time related to the load amount of the load to be dried can be used to quickly determine the first drying time and the first remaining drying time. In other words, by adopting the solution provided by the embodiment of the present disclosure, the first remaining drying time for estimating the remaining drying time can be determined quickly, and the first remaining drying time can be displayed quickly, so that the user can obtain the estimated remaining drying time as early as possible.

[0073] As described above, the embodiment of the present disclosure determines the first drying time according to the cumulative triggering time, and the first drying time is positively correlated with the cumulative triggering time. The following will analyze how to determine the first drying time according to the cumulative triggering time.

[0074] In one embodiment, the controller uses the following S121-S122 to determine the first drying time according to the accumulated triggering time.

[0075] S121: Determine the load amount to be dried according to the accumulated triggering time.

[0076] In a specific implementation, the load amount of the load to be dried can be determined according to the cumulative trigger time. The following methods can be used: (1) searching a predetermined comparison table according to the cumulative trigger time, and determining the load level corresponding to the cumulative trigger time as the load amount of the load to be dried; (2) substituting the cumulative trigger time into a predetermined function relationship to obtain an estimated load amount of the load to be dried.

[0077] In specific implementation, because the cumulative trigger duration itself has a certain degree of randomness, its data does not completely correspond to the actual load amount of the load to be dried. Therefore, in actual applications, the load amount of the load to be dried determined according to the cumulative trigger duration can be expressed in load amount levels.

[0078] S122: Determine the first drying time according to the load amount.

[0079] After determining the load amount of the load to be dried, the controller may then determine the first drying time according to the load amount.

[0080] In some embodiments, the controller stores a table of correspondences between load and drying time, and the first drying time corresponding to the load can be determined by searching the table of correspondences. In other embodiments, the controller stores a functional relationship between the load and the drying time. Substituting the load into the aforementioned functional relationship, the first drying time can be obtained.

[0081] In some practical applications, the load to be dried may be large and difficult to fully spread. At this time, the first drying time directly determined based on the load may be shorter than the actual drying time, resulting in a large error in the estimation of the remaining drying time.

[0082] In order to solve the problem mentioned in the previous paragraph, in some embodiments, the controller may also execute the following S130 - S140 .

[0083] S130: Determine whether the accumulated trigger duration reaches the preset trigger duration; if so, execute S140.

[0084] S140: Determine a duration adjustment coefficient according to the accumulated trigger duration.

[0085] If the cumulative trigger duration reaches the preset trigger duration, it indicates that the actual load to be dried is large and the load is difficult to unfold. In this case, it is necessary to determine the duration adjustment coefficient based on the cumulative trigger duration. The duration adjustment coefficient in the embodiment of the present disclosure is greater than 1 and is positively correlated with the cumulative trigger duration. In other words, the greater the cumulative trigger duration, the greater the corresponding duration adjustment coefficient.

[0086] In some embodiments, the controller stores a correspondence between each cumulative trigger duration period greater than the preset trigger duration and the corresponding duration adjustment coefficient. After determining that the cumulative trigger duration reaches the preset trigger duration, the duration adjustment coefficient can be determined by searching the aforementioned correspondence.

[0087] In the case of determining the duration adjustment coefficient, the aforementioned S122 determining the first drying time according to the load amount may include S1221-S1222.

[0088] S1221: Determine the corresponding preset drying time according to the load amount.

[0089] In some embodiments, determining the corresponding preset drying time according to the load amount is similar to the previous method, and is implemented by table lookup or function calculation, which will not be repeated here. For details, please refer to the previous description.

[0090] S1222: Determine the first drying time according to the preset drying time and the time adjustment coefficient.

[0091] After determining the preset drying time, the preset drying time and the time adjustment coefficient are then multiplied to obtain the first drying time. As previously analyzed, because the time adjustment coefficient is greater than 1, the first drying time must be greater than the preset drying time.

[0092] As analyzed above, the first remaining drying time can only be determined after at least the first time has passed by using the aforementioned S110-S120. Before reaching the first time, the user needs to wait for a certain period of time to learn about the information of the first remaining drying time. In order to prompt and inform the user that the clothes processing device is preparing to calculate the first remaining drying time, the controller can also control the clothes processing device to execute the following S150.

[0093] S150: Displaying a prompt message indicating that the drying countdown is in progress.

[0094] In the embodiment of the present disclosure, when displaying the prompt information that the drying countdown is being calculated, it may be displaying prompt information such as “the drying countdown is being calculated” or the like.

[0095] As analyzed above, the clothes processing device can determine the first remaining drying time only after performing the first drying time. For the convenience of the user, while displaying the prompt information for the drying countdown calculation, the countdown can also be started from the first time to indicate how long it will take to display the first remaining drying time.

[0096] It should be noted that the first remaining drying time determined by the aforementioned method is only a rough estimated drying time, and its prediction accuracy may not be as accurate as that of determining the remaining drying time by humidity detection.

[0097] Figure 2 1 is a flow chart of a control method for a clothing processing device provided in some other embodiments of the present disclosure. Figure 2 As shown, in some other embodiments, the control method of the clothing processing device includes S210-S280.

[0098] S210: Determine to start the drying operation of the load to be dried, and count the cumulative triggering time of the receiving sensor according to the received trigger signal, where the trigger signal is a signal generated when the contact sensor contacts the load to be dried.

[0099] S220: When the running time of the drying operation reaches the first running time, the first drying time is determined according to the cumulative trigger time, and the first remaining drying time is determined according to the first drying time and the running drying time of the clothing processing device, wherein the first drying time is positively correlated with the cumulative trigger time.

[0100] S230: Countdown display starts from the first remaining drying time.

[0101] S210-S220 are the same as S110-S120 in the above embodiment, and will not be repeated here. For details, please refer to the above description. It should be noted that in the process of executing the above S210-S220, the above S130-S140 or the above S150 may also be executed, and will not be repeated here. For details, please refer to the above description.

[0102] S240: When the running time of the drying operation reaches the second running time, detecting a first air humidity of the air in the clothes treating tub of the clothes treating apparatus.

[0103] Different from the previous embodiments, in the embodiments of the present disclosure, when the running time of the drying operation reaches the second running time, the controller controls the humidity sensor in the clothing processing device to operate to detect the first air humidity of the air in the clothing processing barrel of the clothing processing device.

[0104] In the embodiment of the present disclosure, the first air humidity of the air in the laundry treatment tub is detected after the first remaining drying time is determined, so it can be determined that the second operation time is greater than the first operation time. In other embodiments, the second operation time can also be equal to the first operation time or less than the first operation time, which is not limited in the embodiment of the present disclosure.

[0105] In practical applications, in order for the first air humidity to accurately represent the humidity characteristics in the laundry treatment tub of the laundry treatment device, the first air humidity should be detected after the laundry treatment device has been running for a period of time to stabilize the air humidity in the laundry treatment tub.

[0106] S250: When the running time of the drying operation reaches the third running time, detecting the second air humidity of the air in the laundry processing tub.

[0107] In the embodiment of the present disclosure, after the running time of the drying operation reaches the third running time, the controller controls the humidity sensor of the laundry processing device to detect the second air humidity of the air in the laundry processing tub again. Please note that the third running time is greater than the first running time.

[0108] In order to reasonably estimate the remaining drying time according to the first air humidity and the second air humidity, the third operation time should be a longer time. In specific implementation, the third operation time can be preset or determined according to the first drying time mentioned above, preferably determined according to the first drying time.

[0109] In the case where the third operating time needs to be determined according to the first drying time, the third operating time can be obtained by multiplying the first drying time by a set coefficient.

[0110] S260: Calculate the humidity difference between the first air humidity and the second air humidity.

[0111] After determining the first air humidity and the second air humidity, the controller may then subtract the second air humidity from the first air humidity to obtain a humidity difference.

[0112] S270: Determine a second drying time according to the humidity difference, and determine a second remaining drying time according to the second drying time and the drying time already run by the clothes processing device.

[0113] Because the aforementioned second operating time and third operating time are determined operating time, the intermediate drying time from the time point corresponding to the second operating time to the time point corresponding to the third operating time is determined. If the humidity difference is larger, it indicates that the dryness change of the load to be dried after the intermediate drying time is larger, that is, the drying speed of the load to be dried is faster. Accordingly, it can be determined that the second drying time is shorter. That is to say, in the embodiment of the present disclosure, the second drying time is inversely correlated with the humidity difference.

[0114] In a specific implementation, the second drying time is determined according to the humidity difference, and the second drying time can be determined by looking up a table or calculating with a preset formula.

[0115] After the second drying time is obtained, the second remaining drying time can be obtained by subtracting the current drying time of the clothes processing device from the second drying time.

[0116] S280: Continue the countdown display starting from the second remaining drying time.

[0117] Because the humidity detection method can determine the remaining drying time more accurately than the contact sensor detection method, in the embodiment of the present disclosure, after the second remaining drying time is determined by the humidity detection method, the currently displayed remaining drying time is modified to the second remaining drying time to continue the countdown display from the second remaining drying time.

[0118] Figure 3 1 is a flow chart of a control method for a clothing processing device provided in some other embodiments of the present disclosure. Figure 3 As shown, in some other embodiments, the control method of the clothing processing device includes S310-S360.

[0119] S310: Determine to start the drying operation of the load to be dried, and count the cumulative triggering time of the receiving sensor according to the received trigger signal, where the trigger signal is a signal generated when the contact sensor contacts the load to be dried.

[0120] S320: When the running time of the drying operation reaches the first running time, the first drying time is determined according to the cumulative trigger time, and the first remaining drying time is determined according to the first drying time and the running drying time of the clothing processing device, wherein the first drying time is positively correlated with the cumulative trigger time.

[0121] S330: Countdown display starts from the first remaining drying time.

[0122] S310-S330 are the same as S110-S130 in the above embodiment, and will not be repeated here. For details, please refer to the above description. It should be noted that in the process of executing the above S310-S330, the above S140-S150 or the above S160 may also be executed, and will not be repeated here. For details, please refer to the above description.

[0123] S340: Detect the real-time air humidity of the air in the clothes processing drum of the clothes processing device, and determine whether the real-time air humidity reaches the target air humidity; if so, execute S350.

[0124] In the disclosed embodiment, the controller controls the humidity sensor of the laundry processing device to perform periodic humidity detection to determine the real-time air humidity of the air in the laundry processing barrel. After detecting the real-time air humidity, the controller determines whether the real-time air humidity has reached the target air humidity. If the real-time air humidity has not reached the target air humidity, S340 is continued to be executed. If the real-time air humidity has reached the target air humidity, S350 is executed.

[0125] In order to ensure that the humidity detection execution time and the third drying time determined based on the target air humidity are relatively accurate, in the embodiment of the present disclosure, the target air humidity may be set to a reasonable humidity, for example, it may be set to 40%-60%.

[0126] S350: Determine a third drying time according to the humidity detection execution time, and determine a second remaining drying time according to the third drying time and the running drying time of the clothes processing device.

[0127] In the disclosed embodiment, the humidity detection execution duration is the duration determined by the aforementioned periodic humidity detection. In a specific application, the humidity detection is performed from the beginning of drying, and the humidity detection duration is the actual drying duration of the clothing processing device. In another specific application, the humidity detection starts when the drying operation runs to a first running duration, and the humidity detection duration is obtained by subtracting the first running duration from the actual drying duration. In some further specific applications, the humidity detection starts when the running duration of the drying operation reaches a fourth running duration, and the fourth running duration is different from the aforementioned first running duration, and the humidity detection duration is obtained by subtracting the fourth running duration from the actual running duration.

[0128] According to the drying process, the length of the humidity detection time is positively correlated with the load of the load to be dried in the clothes treatment barrel. The longer the humidity detection time, the greater the load of the load to be dried in the clothes treatment barrel, and the longer the third drying time required to dry the load to be dried.

[0129] In the embodiment of the present disclosure, the third drying time is determined according to the humidity detection execution time, and the third drying time can be determined by table lookup or preset function calculation. For example, in one embodiment, after the humidity detection execution time is determined, the humidity detection execution time is multiplied by a preset coefficient to obtain the third drying time. It should be noted that the aforementioned preset coefficient is greater than 1.

[0130] After the third drying time is determined, the second remaining drying time may be obtained by subtracting the already running drying time of the clothes processing device from the third drying time.

[0131] S360: Continue the countdown display starting from the second remaining drying time.

[0132] Because the humidity detection method can determine the remaining drying time more accurately than the contact sensor detection method, in the embodiment of the present disclosure, after the second remaining drying time is determined by the humidity detection method, the currently displayed remaining drying time is modified to the second remaining drying time to continue the countdown display from the second remaining drying time.

[0133] As stated above, after determining the second remaining drying time, the currently displayed remaining drying time will be modified to the second remaining drying time, so that the countdown display will continue from the second remaining drying time. In actual applications, it may happen that the second remaining drying time is longer than the currently displayed remaining drying time. If the countdown display continues from the second remaining drying time in the above manner in this case, the remaining drying time will rebound, resulting in a poor user experience.

[0134] In order to solve the above problem, in the embodiment of the present disclosure, before executing the aforementioned S280 or S360, the controller will also execute the following S410.

[0135] S410: Determine whether the second remaining drying time is less than the remaining drying time currently being displayed.

[0136] If it is determined that the second remaining drying time is less than the remaining drying time currently being displayed, it is determined that the countdown display will continue from the second remaining drying time and there will be no problem of the remaining drying time rebounding, and the aforementioned S280 or S260 can be executed at this time. If the second remaining drying time is greater than or equal to the remaining drying time currently being displayed, the countdown display will no longer start from the second remaining drying time.

[0137] In addition to providing the aforementioned control method for a clothes treating apparatus, an embodiment of the present disclosure also provides a control device for a clothes treating apparatus.

The coefficient determination unit determines the duration adjustment coefficient according to the cumulative trigger duration when the cumulative trigger duration reaches the preset trigger duration, and the duration adjustment coefficient is greater than 1 and is positively correlated with the cumulative trigger duration; correspondingly, the drying duration estimation unit 402 determines the corresponding preset drying duration according to the load amount, and then determines the first drying time according to the preset drying duration and the duration adjustment coefficient.

[0143] In some embodiments, before the running time of the drying operation reaches the first time length, the display control unit controls the display device to display a prompt message indicating that the drying countdown calculation is in progress.

[0144] In some embodiments, the control device 400 of the laundry treating apparatus further includes a first humidity detection unit and a humidity calculation unit.

[0146] The humidity calculation unit is used to calculate a humidity difference between the first air humidity and the second air humidity.

[0147] The drying time estimation unit 402 is further used to determine a second drying time according to the humidity difference, and to determine a second remaining drying time according to the second drying time and the running drying time of the clothing processing device, wherein the second drying time is inversely correlated with the humidity difference.

[0148] In some embodiments, the first humidity detection unit determines the third operating time according to the first drying time.

[0149] In some embodiments, the control device 400 of the laundry processing apparatus further comprises a second humidity detection unit. The second humidity detection unit detects the real-time air humidity of the air in the laundry processing tub of the laundry processing apparatus and determines whether the real-time air humidity reaches the target air humidity.

[0150] The drying time estimation unit 402 is also used to determine the third drying time according to the humidity detection execution time when the real-time air humidity reaches the target air humidity, and determine the second remaining drying time according to the third drying time and the running drying time of the clothing processing device.

[0151] In some embodiments, the second humidity detection unit starts to detect the real-time air humidity when the running time of the drying operation reaches a fourth running time.

[0152] In some embodiments, the control device 400 of the laundry processing device further includes a judgment unit, which is used to judge whether the second remaining drying time is less than or equal to the remaining drying time being displayed. When the second remaining drying time is less than the remaining drying time being displayed, the display control unit continues the countdown display from the second remaining drying time.
