A laundry dryer is a clean household appliance that uses electric heating to evaporate and dry the moisture in the washed laundry immediately. The laundry dryer is especially needed when laundry is difficult to dry in winter in the north and in "continuous humid weather" in the south.
With the popularization of the laundry dryer, people have increasingly high requirements for the performance of a laundry dryer, and the disadvantages of a laundry dryer are exposed more and more. When the laundry to be dried is made of chemical fiber, the laundry dryer easily mistakenly determines that the laundry which has not been dried off yet has been dried off due to the chemical fiber, and a remaining duration displayed on a display panel of the laundry dryer jumps directly to the end, resulting in poor drying effect of the laundry made of chemical fiber and affecting the drying experience of the user.

DETAILED DESCRIPTION

In order to make objectives, technical solutions and advantages of the application more clear, the application will be further described in detail below in combination with the drawings, and the described embodiments should not be considered as a limitation to the application. All other embodiments obtained by ordinary skill in the art without creative labor fall within the scope of protection of the application.
In the following description, the terms "first\second\third" are used only to distinguish similar objects from each other and do not represent a specific order of the objects. It is understood that the terms "first\second\third" may, where permitted, be interchanged with each other in a specific order or in a sequence to enable the embodiments of the application described herein to be implemented in a sequence other than that illustrated or described herein.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the application belongs. The terms used herein are only for the purpose of describing embodiments of the application and are not intended to limit the application.
In the related art, a laundry treatment apparatus, such as a laundry dryer and a laundry washer-dryer, easily mistakenly determines that laundry which has not been dried off yet has been dried off in a drying process due to chemical fiber of the laundry, and a remaining duration displayed on a display panel of the laundry treatment apparatus jumps directly to the end, resulting in poor drying effect of laundry made of chemical fiber. On this basis, an embodiment of the application provides a method for controlling laundry drying, which is applied to a laundry treatment apparatus. The method according to the embodiment of the application may be implemented by computer programs which perform each of operations in the method for controlling laundry drying according to the embodiment of the application when executed. In some embodiments, the computer programs may be executed by a processor in the laundry treatment apparatus. FIG. 1 is a schematic flowchart of a method for controlling laundry drying according to an embodiment of the application. As shown in FIG. 1, the method for controlling laundry drying includes the following operations.
At S101, a drying process is entered, and a humidity level of an object to be dried is initialized into a first humidity level.
The method for controlling laundry drying according to the embodiment of the application is applied to a laundry treatment apparatus, which may be an apparatus with drying function such as the laundry washer-dryer and the laundry dryer. The object to be dried may be a laundry, shoes, a bag, and the like to be washed. In the embodiment of the application, the laundry treatment apparatus is described by taking the laundry washer-dryer as an example, and the object to be dried is described by taking a laundry to be dried as an example. Unless specifically described below, the laundry treatment apparatus refers to the laundry washer-dryer, and the object to be dried refers to the laundry to be dried.
The working principle of the laundry washer-dryer according to the embodiment of the application is as follows: dry cold air is heated into dry hot air by a heating device; the dry hot air changes into moist hot air after passing through the laundry to be dried; the moist hot air changes into dry cold air and condensed water after passing through a condenser; the condensed water is discharged from a drain pipe; said dry cold air is changed into dry hot air by the heating device again, said dry hot air passes through the laundry to be dried; the operations described above are repeated. In this way, the moisture of the laundry to be dried is taken away, to achieve the purpose of drying the laundry.
The user places the laundry to be dried into a tub of the laundry washer-dryer and selects a drying procedure, and then presses a "start/pause" button to allow the laundry washer-dryer to enter the drying process. The laundry treatment apparatus controls the heating device thereof to start heating. The first humidity level is a level of a humidity value of the laundry to be dried before the drying process is performed, that is, a level of a humidity value of the laundry to be dried after the laundry to be dried is dehydrated.
In an embodiment of the application, a humidity level of the laundry to be dried includes a first humidity level, a second humidity level, a third humidity level, a fourth humidity level and a drying humidity level, which are respectively denoted as L0, L1, L2, L3 and L4. The laundry to be dried has a maximum humidity at the first humidity level L0, a greater humidity at the second humidity level L1, a general humidity at the third humidity level L2, a drier humidity (i.e., a lower humidity) at the fourth humidity level L3, and a minimum humidity at the fifth humidity level L4. In a case that the laundry to be dried is at the fifth humidity level L4, the laundry to be dried has been dried off.
At S102, a display panel of the laundry treatment apparatus is controlled to display a first remaining drying duration.
Here, the first remaining drying duration is determined according to a first working duration corresponding to the first humidity level, and a first dried duration (the first dried duration refers to a duration for which the object to be dried has been dried at the first humidity level) at the first humidity level. In practice, a difference between the first working duration and the first dried duration may be determined as the first remaining drying duration.
In an embodiment of the application, the first working duration corresponding to the first humidity level L0, a second working duration corresponding to the second humidity level L1, a third working duration corresponding to the third humidity level L2, a fourth working duration corresponding to the fourth humidity level L3 and a fifth working duration corresponding to the drying humidity level L4 meet the following requirements: the first working duration corresponding to the first humidity level > the second working duration corresponding to the second humidity level > the third working duration corresponding to the third humidity level > the fourth working duration corresponding to the fourth humidity level > the fifth working duration corresponding to the drying humidity level. Here, since the laundry to be dried has been dried off at the drying humidity level, there is no need to continue the drying process. As such, the fifth working duration may be set to be 0.
In a case that a current humidity level is the first humidity level, a duration required for drying the laundry to be dried is preset as the first working duration. At the first humidity level, the duration required for drying the laundry to be dried is the longest, and the first remaining drying duration displayed on the display panel is counted down from the first working duration.
For example, the first working duration is 4 hours, and the first remaining drying duration initially displayed on the display panel is "04:00:00". At the first humidity level, the first remaining drying duration begins to decrease with the increase of the first dried duration. That is, the first remaining drying duration displayed on the display panel gradually decreases from "04:00:00" to "03:59:59", "03:59:58", ....
At S103, it is determined that a humidity value of the object to be dried reaches a stable condition, and in a case that the humidity value meets a level update condition, the humidity level of the object to be dried is updated to a next humidity level of a current humidity level.
In the related art, since the humidity value of the object to be dried is detected when the humidity value of the object to be dried is uneven, the obtained humidity value is unstable. When the humidity value of the laundry to be dried located in a drier position is detected, the detected humidity value is small. In a case that the humidity level of the laundry to be dried is determined according to the detected humidity value at this time, the humidity level of the laundry to be dried is higher than the actual humidity level of the laundry to be dried. For example, if the actual humidity level of the laundry to be dried is L2, the humidity level of the laundry to be dried may be mistakenly determined as L3 when the humidity value of the laundry to be dried located in a drier position is detected; and the detected humidity value is greater when the humidity value of the laundry to be dried located in a wetter position is detected. In a case that the humidity level of the laundry to be dried is determined according to the detected humidity value of the laundry to be dried located in the wetter portion, the determined humidity level of the laundry to be dried will be lower than the actual humidity level of the laundry to be dried. For example, if the actual humidity level of the laundry to be dried is L2, the humidity level of the laundry to be dried may be mistakenly determined as L1 when the humidity value of the laundry to be dried located in the wetter position is detected. Especially for laundries to be dried made of chemical fiber, the difference of humidity values of the laundries to be dried located in different positions is more significant due to the poor water absorption of the chemical fiber, which leads to a greater probability of mistaken determination.
In the embodiment of the application, when it is determined that the humidity value of the laundry to be dried reaches the stable condition, that is, when it is ensured that the difference of the moisture of the laundries to be dried located in different positions is not significant, the humidity value of the object to be dried is detected. In this way, the error between the detected humidity value and the actual humidity value of the object to be dried may be reduced, the possibility that the detected humidity value is inconsistent with the actual humidity value may be reduced, and the accuracy of the detected humidity value may be improved, thereby ensuring that mistaken determination is not occurred when it is determined whether the updated humidity level is reached, and ensuring that the expected drying effect is achieved.
In the embodiment of the application, when the humidity value of the object to be dried does not reach the stable condition, or when the humidity value of the object to be dried reaches the stable condition, but the humidity value does not meet the level update condition, the drying process is continued at the first humidity level, until the humidity value of the object to be dried reaches the stable condition, and the humidity value meets the level update condition, and then operation S 105 is entered.
At S 104, the display panel is controlled to display a second remaining drying duration.
Here, the second remaining drying duration is determined according to a second working duration corresponding to the next humidity level, and a second dried duration (the second dried duration refers to a duration for which the object to be dried has been dried at the next humidity level) at the next humidity level. The second remaining drying duration is less than the first remaining drying duration. In practice, a difference between the second working duration and the second dried duration may be determined as the second remaining drying duration.
When the laundry to be dried is originally drier, that is, the actual humidity value of the laundry to be dried is small, or when the laundry to be dried is originally wetter but the humidity value of the laundry to be dried reaches the stable condition and the humidity value meets the level update condition after drying for a period of time, the first remaining drying duration displayed on the display panel jumps to the second remaining drying duration, where the second remaining drying duration is less than the first remaining drying duration.
For example, when the actual humidity value of the laundry to be dried corresponds to the second humidity level, the first remaining drying duration displayed on the display panel is counted down from the first working duration. At this time, the humidity value of the laundry to be dried reaches the stable condition, and the humidity value meets the level update condition, then the first remaining drying duration displayed on the display panel is updated to the second remaining drying duration.
Taking the second working duration of 3 hours as an example, the first remaining drying duration initially displayed on the display panel is "04:00:00". It takes 2 minutes to determine that the humidity value of the laundry to be dried reaches the stable condition and the humidity value meets the level update condition. At this time, the first remaining drying duration displayed on the display panel is "03:58:00", and the first remaining drying duration displayed on the display panel is updated to the second remaining drying duration, that is, jumping from "03:58:00" to "03:00:00". Then, at the second humidity level, the second remaining drying duration begins to decrease with the increase of the second dried duration, that is, the second remaining drying duration displayed on the display panel gradually decreases from "03:00:00" to "02:59:59", "02:59:58", ....
As another example, when the actual humidity value of the laundry to be dried corresponds to the first humidity level, the first remaining drying duration displayed on the display panel is counted down from the first working duration, and after working for 0.5 hours, the first remaining drying duration displayed on the display panel is "03:00:00". In a case that the humidity value of the laundry to be dried reaches the stable condition, and the humidity value meets the level update condition, the first remaining drying duration displayed on the display panel is updated to the second remaining drying duration.
Taking the second working duration of 3 hours as an example, the second remaining drying duration is determined according to the second working duration corresponding to the second humidity level, and the second dried duration (here, the second dried duration refers to a duration for which the laundry to be dried has been dried at the second humidity level) at the second humidity level. At this time, the second dried duration of the laundry washer-dryer at the second humidity level is 0, that is, the first remaining drying duration displayed on the display panel is updated to the second working duration, that is, jumping from "03:30:00" to "03:00:00". Then, at the second humidity level, the second remaining drying duration begins to decrease with the increase of the second dried duration, that is, the second remaining drying duration displayed on the display panel gradually decreases from "03:00:00" to "02:59:59", "02:59:58", ....
In the method for controlling laundry drying according to the embodiment of the application, after the humidity value of the object to be dried is stable, and when the humidity value meets the level update condition, the remaining drying duration displayed on the display panel is updated gradually according to the humidity level of the object to be dried, to ensure that the expected drying effect is achieved, and avoid the situation that the remaining drying duration displayed on the display panel jumps too fast or even jumps directly to 0 when the detected humidity value is inconsistent with the actual humidity value of the object to be dried.
In the method for controlling laundry drying according to the embodiment of the application, after the laundry treatment apparatus enters the drying process, the humidity level of the object to be dried is initialized into the first humidity level. The display panel of the laundry treatment apparatus is controlled to display the first remaining drying duration, where the first remaining drying duration is determined according to the first working duration corresponding to the first humidity level, and the first dried duration at the first humidity level. It is determined that the humidity value of the object to be dried reaches the stable condition, and in a case that the humidity value meets the level update condition, the humidity level of the object to be dried is updated to a next humidity level of a current humidity level. The display panel is controlled to display a second remaining drying duration, where the second remaining drying duration is determined according to a second working duration corresponding to the next humidity level, and a second dried duration at the next humidity level. Herein, the second remaining drying duration is less than the first remaining drying duration. In this way, after the humidity value of the object to be dried is stable, and in a case that the humidity value meets the level update condition, the remaining drying duration displayed on the display panel is updated according to the humidity level of the object to be dried, which may not only reduce the error between the acquired humidity value and the actual humidity value of the object to be dried, but also gradually update the remaining drying duration according to the humidity level of the object to be dried, to ensure that the expected drying effect is achieved.
In some embodiments, after the above operation S103, the method for controlling laundry drying may further include operation S03. At S03, it is determined whether the humidity value of the object to be dried reaches the stable condition.
In one implementation, the operation S03 may include the following operations.
At S03a1, a current dried duration (the current dried duration refers to a duration for which the object to be dried has been dried at the current humidity level) at the current humidity level is acquired.
At S03a2, in a case that the current dried duration reaches a stabilization duration corresponding to the current humidity level, it is determined that the humidity value of the object to be dried reaches the stable condition.
In this implementation, it is determined whether a current humidity value reaches the stable condition according to the current dried duration at the current humidity level. For example, when the first dried duration at the first humidity level reaches a preset first duration threshold, it is determined that the humidity value of the object to be dried reaches the stable condition.
Here, the first duration threshold may be set to be any value ranging between 100 and 180 seconds.
In another implementation, the operation S03 may include the following operations.
At S03b1, a plurality of humidity values detected at the current humidity level are acquired.
In actual implementation, the plurality of humidity values acquired may be a plurality of humidity values which are continuously acquired or a plurality of humidity values which are randomly acquired; and the acquisition may be periodic acquisition or random acquisition, which are not limited by the embodiment of the application.
At S03b2, a difference between a maximum humidity value and a minimum humidity value among the plurality of humidity values is calculated.
At S03b3, in a case that the difference is less than a difference threshold corresponding to the current humidity level, it is determined that the humidity value of the object to be dried reaches the stable condition.
In this implementation, it is determined whether the current humidity value reaches the stable condition according to the humidity values detected multiple times. For example, at the first humidity level, the humidity value of the object to be dried is detected 10 times to obtain 10 humidity values. The difference between the maximum humidity value and the minimum humidity value among the 10 humidity values is 50 g/m³. The difference threshold corresponding to the first humidity level is 100 g/m³. The difference 50 g/m³ is less than the difference threshold 100 g/m³ corresponding to the first humidity level, thus it is determined that the humidity value of the object to be dried reaches the stable condition.
Here, the difference threshold may be set by the user in combination with the actual situations, and may also be a default value which is set when the laundry washer-dryer leaves the factory, which is not limited by the embodiment of the application.
In some embodiments, after it is determined that the humidity value of the object to be dried reaches the stable condition in the above operation S03a2 or the above operation S03b3, the method for controlling laundry drying may further include operation S04. At S04, it is determined whether the humidity value of the object to be dried meets the level update condition.
In one implementation, the above operation S04 may include the following operations.
At S04a1, the humidity value of the object to be dried is acquired.
At S04a2, in a case that the humidity value of the object to be dried is less than a humidity value corresponding to the next humidity level, it is determined that the humidity value of the object to be dried meets the level update condition.
In an embodiment of the application, a humidity value corresponding to the first humidity level L0, a humidity value corresponding to the second humidity level L1, a humidity value corresponding to the third humidity level L2, a humidity value corresponding to the fourth humidity level L3 and a humidity value corresponding to the drying humidity level L4 meet the following requirements: the humidity value corresponding to the first humidity level > the humidity value corresponding to the second humidity level > the humidity value corresponding to the third humidity level > the humidity value corresponding to the fourth humidity level > the humidity value corresponding to the drying humidity level.
In this implementation, after it is determined that the humidity value of the object to be dried reaches the stable condition, the humidity value of the object to be dried is detected. When the humidity value detected one time is less than the humidity value corresponding to the next humidity level, it is determined that the humidity value of the object to be dried meets the level update condition.
In another implementation, the above operation S04 may include the following operations.
At S04b1, the humidity value of the object to be dried is acquired.
At S04b2, in a case that the humidity value of the object to be dried is less than a humidity value corresponding to the next humidity level and a duration for which the humidity value of the object to be dried is maintained to be less than the humidity value corresponding to the next humidity level reaches a maintain duration corresponding to the current humidity level, it is determined that the humidity value of the object to be dried meets the level update condition.
In an embodiment of the application, a humidity value corresponding to the first humidity level L0, a humidity value corresponding to the second humidity level L1, a humidity value corresponding to the third humidity level L2, a humidity value corresponding to the fourth humidity level L3 and a humidity value corresponding to the drying humidity level L4 meet the following requirements: the humidity value corresponding to the first humidity level > the humidity value corresponding to the second humidity level > the humidity value corresponding to the third humidity level > the humidity value corresponding to the fourth humidity level > the humidity value corresponding to the drying humidity level.
In this implementation, after it is determined that the humidity value of the object to be dried reaches the stable condition, the humidity value of the object to be dried is detected. When each of a plurality of humidity values which are detected multiple times in a preset maintain duration is less than the humidity value corresponding to the next humidity level, it is determined that the humidity value of the object to be dried meets the level update condition. Otherwise, when the above requirement is not met, it is determined that the humidity value of the object to be dried does not meet the level update condition.
Here, the maintain duration may be set to be any value ranging between 20 and 200 seconds.
In the first implementation, the humidity value of the object to be dried is detected one time. In the second implementation, the humidity value of the object to be dried is detected multiple times in a duration for which the humidity value of the object to be dried is maintained to be less than the humidity value corresponding to the next humidity level. In this way, the second implementation further ensures that when the humidity value of the object to be dried is stable and is maintained to be less than the humidity value corresponding to the next humidity level, the remaining drying duration displayed on the display panel is updated according to the humidity level of the object to be dried. Therefore, compared with the first implementation, the second implementation may further reduce the error between the acquired humidity value and the actual humidity value of the object to be dried, to ensure that the expected drying effect is achieved.
In some embodiments, after the above operation S105, the method for controlling laundry drying may further include the following operations.
At S106, in a case that determining that the updated humidity level is a drying humidity level, the drying process is ended, and a heating device of the laundry treatment apparatus is controlled to stop heating.
In a case that the updated humidity level is the drying humidity level L4, the laundry to be dried has been dried off. At this time, the drying process is ended, and the heating device is controlled to stop heating.
At S107, a cooling process is entered, and a cooling device of the laundry treatment apparatus is controlled to start working.
After the heating device stops heating, the temperature of the laundry that has been dried off in the laundry washer-dryer is relatively high. In order to decrease the temperature of the laundry that has been dried off and prevent the higher temperature of the laundry that has been dried off from damaging the skin of the user after the door is opened, the laundry treatment apparatus is controlled to enter the cooling process after the drying process is ended.
Here, the cooling device may be a fan. Cold air is fed into the tub of the laundry washer-dryer through the fan, and passes through the laundry with the higher temperature that has been dried off to take away the heat. The above operations are repeated to allow the heat of the laundry that has been dried off to be taken away, to achieve the purpose of cooling the laundry that has been dried off.
At S108, the display panel is controlled to display a remaining cooling duration.
Here, the remaining cooling duration is determined according to a preset cooling working duration and a cooled duration (the cooled duration refers to a duration for which the object that has been dried off has been cooled).
In actual implementation, a difference between the preset cooling working duration and the cooled duration is determined as the remaining cooling duration.
At S109, in a case that the remaining cooling duration reaches a preset duration, the cooling device is controlled to stop working.
Here, the preset duration may be set to be 0. That is, after the cooling device is controlled to work for a fixed cooling working duration, the cooling process is ended, and the cooling device is controlled to stop working.
In another implementation, the operation S109 may be replaced with operation S 109'. At S 109', the cooling device is controlled to stop working in a case that the temperature in the laundry treatment apparatus is less than a preset temperature.
In this implementation, a working duration of the cooling device is non-fixed. When there are fewer laundries that have been dried off, the temperature in the laundry washer-dryer decreases rapidly, to allow the working duration of the cooling device to be shortened by adopting this implementation. When there are more laundries that have been dried off, the temperature in the laundry washer-dryer decreases slowly, to ensure that the temperature of the laundry that has been dried off will not damage the user after the cooling process is ended by adopting this implementation. The cooling device is controlled to stop working according to the temperature in the tub, which allows the cooling device to be controlled more flexibly, and ensures that the temperature of the laundry that has been dried off will not damage the user.
FIG. 2 is another schematic flowchart of a method for controlling laundry drying according to an embodiment of the application, which is applied to a laundry treatment apparatus. As shown in FIG. 2, the method for controlling laundry drying according to the embodiment of the application includes the following operations.
At S201, a drying process is entered, and a heating device of the laundry treatment apparatus is controlled to start heating.
At S202, a humidity level of an object to be dried is initialized into a first humidity level.
At S203, a display panel of the laundry treatment apparatus is controlled to display a first remaining drying duration.
Here, the first remaining drying duration is determined according to a first working duration corresponding to the first humidity level, and a first dried duration (the first dried duration refers to a duration for which the object to be dried has been dried at the first humidity level) at the first humidity level.
At S204, a current dried duration (the current dried duration refers to a duration for which the object to be dried has been dried at a current humidity level) at a current humidity level is acquired.
At S205, it is determined whether the current dried duration reaches a stabilization duration corresponding to the current humidity level.
In a case that the current dried duration reaches the stabilization duration corresponding to the current humidity level, which indicates that a difference of the humidity values of the objects to be dried located in different positions in the laundry treatment apparatus is small, operation S206 is entered. In a case that the current dried duration does not reach the stabilization duration corresponding to the current humidity level, which indicates that a difference of the humidity values of the objects to be dried located in different positions in the laundry treatment apparatus is still greater, the operation S204 is returned to reacquire a new current dried duration.
In some embodiments, the above operation S204 and the above operation S205 may be replaced with operation S204' to operation S206'.
At S204', a plurality of humidity values detected at the current humidity level are acquired.
At S205', a difference between a maximum humidity value and a minimum humidity value among the plurality of humidity values is calculated.
At S206', it is determined whether the difference is less than a difference threshold corresponding to the current humidity level.
In a case that the difference is less than the difference threshold corresponding to the current humidity level, which indicates that a difference of the humidity values of the objects to be dried located in different positions in the laundry treatment apparatus is small, the operation S206 is entered. In a case that the difference is greater than or equal to the difference threshold corresponding to the current humidity level, which indicates that a difference of the humidity values of the objects to be dried located in different positions in the laundry treatment apparatus is still greater, the operation S204' is returned to redetect a plurality of humidity values.
At S206, it is determined that the humidity value of the object to be dried reaches the stable condition.
The humidity value of the object to be dried is acquired after it is determined that a current humidity value is stable, which may avoid a greater error between the acquired humidity value and the actual humidity value of the object to be dried caused by the instability of humidity value, reduce the possibility that the acquired humidity value is inconsistent with the actual humidity value, and improve the accuracy of the acquired humidity value, thereby ensuring that the expected drying effect is achieved.
At S207, the humidity value of the object to be dried is acquired.
The humidity value acquired at this operation is a stable humidity value, that is, the difference between the acquired humidity value and the actual humidity value of the object to be dried is within the error range.
At S208, it is determined whether the humidity value of the object to be dried is less than a humidity value corresponding to the next humidity level.
In a case that the humidity value of the object to be dried is less than the humidity value corresponding to the next humidity level, which indicates that the humidity value of the object to be dried has been brought to the humidity value corresponding to the next humidity level, operation S209 is entered. In a case that the humidity value of the object to be dried is greater than or equal to the humidity value corresponding to the next humidity level, the drying is continued, and then the operation S207 is returned to reacquire a new humidity value.
In some embodiments, after the above operation S208, the method for controlling laundry drying may further include operation S08. At S08, it is determined whether a duration for which the humidity value of the object to be dried is maintained to be less than the humidity value corresponding to the next humidity level reaches a maintain duration corresponding to the current humidity level. In a case that the duration for which the humidity value of the object to be dried is maintained to be less than the humidity value corresponding to the next humidity level reaches the maintain duration corresponding to the current humidity level, which indicates that the humidity value of the object to be dried has been brought to the humidity value corresponding to the next humidity level, the operation S209 is entered. In a case that the duration for which the humidity value of the object to be dried is maintained to be less than the humidity value corresponding to the next humidity level does not reach the maintain duration corresponding to the current humidity level, the drying is continued, and then the operation S207 is returned to reacquire a new humidity value.
At S209, it is determined that the humidity value of the object to be dried meets a level update condition.
At S210, the humidity level of the object to be dried is updated to a next humidity level of the current humidity level.
At S211, the display panel is controlled to display a second remaining drying duration.
Here, the second remaining drying duration is determined according to a second working duration corresponding to the next humidity level, and a second dried duration (the second dried duration refers to a duration for which the object to be dried has been dried at the next humidity level) at the next humidity level. Herein, the second remaining drying duration is less than the first remaining drying duration.
At S212, it is determined whether the updated humidity level is a drying humidity level.
In a case that the next humidity level is not the drying humidity level, which indicates that the object to be dried has not been dried off, the operation S204 is entered. In a case that the next humidity level is the drying humidity level, which indicates that the object to be dried has been dried off, operation S213 is entered.
At S213, the drying process is ended, and the heating device of the laundry treatment apparatus is controlled to stop heating.
At S214, a cooling process is entered, and a cooling device of the laundry treatment apparatus is controlled to start working.
At S215, the display panel is controlled to display a remaining cooling duration.
Here, the remaining cooling duration is determined according to a preset cooling working duration and a cooled duration (the cooled duration refers to a duration for which the object that has been dried off has been cooled).
At S216, it is determined whether the remaining cooling duration reaches a preset duration.
In a case that the remaining cooling duration reaches the preset duration, which indicates that the temperature of the object that has been dried off has been decreased to a safe value which does not damage the user, operation S217 is entered. In a case that the remaining cooling duration does not reach the preset duration, which indicates that the temperature of object that has been dried off is still higher, the operation S216 is continued.
In some embodiments, the operation S216 may be replaced with operation S216'. At S216', it is determined whether a temperature in the laundry treatment apparatus is less than a preset temperature.
In a case that the temperature in the laundry treatment apparatus is less than the preset temperature, which indicates that the temperature of object that has been dried off has been decreased to a safe value which does not damage the user, the operation S217 is entered. In a case that the temperature in the laundry treatment apparatus is greater than or equal to the preset temperature, which indicates that the temperature of object that has been dried off is still higher, the operation S216' is continued.
At S217, the cooling device is controlled to stop working.
In the method for controlling laundry drying according to the embodiment of the application, after the laundry treatment apparatus enters the drying process, the heating device of the laundry treatment apparatus is controlled to start heating, and the humidity level of the object to be dried is initialized into the first humidity level. The display panel of the laundry treatment apparatus is controlled to display the first remaining drying duration. The current dried duration at the current humidity level is acquired. In a case that the current dried duration reaches the stabilization duration corresponding to the current humidity level, it is determined that the humidity value of the object to be dried reaches the stable condition. The humidity value of the object to be dried is acquired. In a case that the humidity value of the object to be dried is less than the humidity value corresponding to the next humidity level, and the duration for which the humidity value of the object to be dried is maintained to be less than the humidity value corresponding to the next humidity level reaches a maintain duration corresponding to the current humidity level, it is determined that the humidity value meets a level update condition. At this time, the humidity level of the object to be dried is updated to a next humidity level of the current humidity level, and the display panel is controlled to display the second remaining drying duration. In this way, after the humidity value of the object to be dried is stable, and in a case that the humidity value meets the level update condition, the remaining drying duration displayed on the display panel is updated according to the humidity level of the object to be dried, which may not only reduce the error between the acquired humidity value and the actual humidity value of the object to be dried, but also gradually update the remaining drying duration according to the humidity level of the object to be dried, to ensure that the expected drying effect is achieved. The above operations are repeated until the next humidity level is the drying humidity level. In a case that the next humidity level is the drying humidity level, the heating device is controlled to stop heating, the cooling process is entered, the cooling device of the laundry treatment apparatus is controlled to start working, and the display panel is controlled to display the remaining cooling duration. In a case that the remaining cooling duration reaches the preset duration, the cooling device is controlled to stop working, which may ensure that the temperature of the laundry that has been dried off has been decreased to the safe value and the laundry that has been dried off does not damage the user when the laundry that has been dried off is taken out.
Hereinafter, an exemplary application of the embodiment of the application in a practical application scenario will be described.
At present, with the increasing development of technology, life becomes more convenient and efficient due to the progress of technology, and more and more people begin to realize the importance of the laundry dryer. As the number of users of the laundry dryer increases, the disadvantages of the laundry dryer are exposed more and more.
In the related art, when the laundries to be dried are few or dry, the laundry dryer determines the humidity level of the laundry to be dried while determining whether the laundry to be dried has been dried off. The laundry dryer mistakenly determines that the laundries which have not been dried off yet have been dried off due to chemical fiber of the laundries to be dried, and the remaining duration displayed on the laundry dryer jumps directly to 0, resulting in poor drying effect of the laundries made of chemical fiber. In addition, the remaining duration displayed on the laundry dryer jumps too fast, resulting in poor use experience.
In order to solve this problem, an embodiment of the application provides an improved method for drying the laundry made of chemical fiber, which may effectively avoid the occurrence of the above problem and provide the user with a good drying experience.
FIG. 3 is yet another schematic flowchart of a method for controlling laundry drying according to an embodiment of the application, which is applied to a laundry treatment apparatus, such as a laundry washer-dryer.

At S303, an initial timing time T is initialized into 0.
At S304, it is determined whether the timing time T reaches T1.
Here, T1 is a first stabilization duration for the humidity value. In a case that T is greater than or equal to T1, which indicates that a humidity value of the laundry to be dried is stable, operation S305 is entered. In a case that T is less than T1, the operation S304 is returned to perform the determination.
At S305, a humidity value HUM during operation is acquired.
Here, the HUM represents a current humidity value.
At S306, it is determined whether the HUM is less than a humidity value corresponding to L1, and whether a duration for which the HUM is maintained to be less than the humidity value corresponding to L1 reaches t1.
Here, L1 represents a greater humidity of the load. In a case that the HUM is less than the humidity value corresponding to L1, and a duration for which the HUM is maintained to be less than the humidity value corresponding to L1 is greater than or equal to t1, operation S307 is entered. Otherwise, in a case that the above requirements are not met, the operation S305 is returned to reacquire a humidity value.

Here, T2 is a second stabilization duration for the humidity value. In a case that T is larger than or equal to T2, which indicates that the humidity value of the laundry to be dried is stable, operation S310 is entered. In a case that T is less than T2, the operation S309 is returned to perform the determination.
At S310, the humidity value HUM during operation is acquired.
At S311, it is determined whether the HUM is less than a humidity value corresponding to L2, and whether a duration for which the HUM is maintained to be less than the humidity value corresponding to L2 reaches t2.
Here, L2 represents a general humidity of the load. In a case that the HUM is less than the humidity value corresponding to L2, and a duration for which the HUM is maintained to be less than the humidity value corresponding to L2 is larger than or equal to t2, operation S312 is entered. Otherwise, in a case that the above requirements are not met, the operation S310 is returned to reacquire a humidity value.
At S312, the humidity level is updated to L2.
At S313, the initial timing time T is initialized to 0.
At S314, it is determined whether the timing time T reaches T3.
Here, T3 is a third stabilization duration for the humidity value. In a case that T is greater than or equal to T3, which indicates that the humidity value of the laundry to be dried is stable, operation S315 is entered. In a case that T is less than T3, the operation S314 is returned to perform the determination.
At S315, the humidity value HUM during operation is acquired.
At S316, it is determined whether the HUM is less than a humidity value corresponding to L3, and whether a duration for which the HUM is maintained to be less than the humidity value corresponding to L3 reaches t3.
Here, L3 represents a drier (that is, a lower humidity) of the load. In a case that the HUM is less than the humidity value corresponding to L3, and a duration for which the HUM is maintained to be less than the humidity value corresponding to L3 is greater than or equal to t3, operation S317 is entered. Otherwise, in a case that the above requirements are not met, the operation S315 is returned to reacquire a humidity value.
At S317, the humidity level is updated to L3.
At S318, the initial timing time T is initialized to 0.
At S319, it is determined whether the timing time T reaches T4.
Here, T4 is a fourth stabilization duration for the humidity value. In a case that T is greater than or equal to T4, which indicates that the humidity value of the laundry to be dried is stable, operation S320 is entered. In a case that T is less than T4, the operation S319 is returned to perform the determination.
At S320, the humidity value HUM during operation is acquired.
At S321, it is determined whether the HUM is less than a humidity value corresponding to L4, and whether a duration for which the HUM is maintained to be less than the humidity value corresponding to L4 reaches t4.
Here, L4 represents a driest (that is, a minimum humidity) of the load. In a case that the HUM is less than the humidity value corresponding to L4, and a duration for which the HUM is maintained to be less than the humidity value corresponding to L4 is greater than or equal to t4, operation S322 is entered. Otherwise, in a case that the above requirements are not met, the operation S320 is returned to reacquire a humidity value.
At S322, the humidity level is updated to L4.
At S323, the drying process is ended.
Herein, L0 represents the maximum humidity of the load, and L4 represents the minimum humidity of the load. The timing time T is a time for stabilizing the humidity value. T1 to T4 may be set to range from 100 to 180 seconds. t1 to t4 is a time in which the humidity value is maintained, which may be set to range from 20 to 200 seconds. In the related art, the laundry dryer determines the humidity level of the laundry made of chemical fiber while determining whether the laundry made of chemical fiber has been dried off. When the laundries made of chemical fiber are few or dry, the laundry dryer jumps directly to L4 to determine that the laundry made of chemical fiber has been dried off, and the display time also jumps in one step. In the improved embodiment of the application, the humidity level may be determined sequentially according to the order from L1 to L4, and the display time may sequentially jump from more time to less time in four stages. The improved embodiment of the application not only prevents the laundry dryer from mistakenly determining that the laundry made of chemical fiber has been dried off, but also provides the user with a good drying experience. The embodiment of the application may reduce the probability of mistaken determination of the laundry made of chemical fiber and improve the satisfaction of the user's use experience by sequentially determining the humidity level of the laundry made of chemical fiber.

The display panel is controlled to display a second remaining drying duration, the second remaining drying duration being determined according to a second working duration corresponding to the next humidity level, and a second dried duration at the next humidity level. In this way, an error between the acquired humidity value and an actual humidity value of the object to be dried may be reduced, and the remaining drying duration is gradually updated according to the humidity level of the object to be dried, to ensure that the expected drying effect is achieved.
