In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

In the following description, references to the terms "first \ second \ third" are only to distinguish similar objects and do not denote a particular order, but rather the terms "first \ second \ third" are used to interchange specific orders or sequences, where appropriate, so as to enable the embodiments of the application described herein to be practiced in other than the order shown 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 this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.

Based on the problem that drying devices in the related art, such as clothes dryers, dish washers and the like, are poor in drying effect, the embodiment of the application provides a drying method applied to the drying devices. The method provided by the embodiment of the application can be realized through a computer program, and when the computer program is executed, all steps in the drying method provided by the embodiment of the application are completed. In some embodiments, the computer program may be executable by a processor in the drying apparatus. Fig. 1 is a schematic flow chart of an implementation of a drying method provided in an embodiment of the present application, and as shown in fig. 1, the drying method includes the following steps:

step S101, determining to enter a drying stage, and starting a heating device of the drying equipment to dry the object to be dried.

In the embodiment of the application, the drying device may be any device with a drying function, such as a clothes dryer, a shoe dryer, a clothes care machine, a dish washer, a washing and drying all-in-one machine, and the corresponding object to be dried may be clothes, shoes, bags, bowls and chopsticks, etc. The drying apparatus is taken as a dryer as an example, and the object to be dried is taken as clothes to be dried as an example for explanation. The clothes dryer can be a heat pump clothes dryer or a condensation clothes dryer.

After the user starts the dryer, the dryer enters a drying stage. Because clothing initial humidity is bigger, and its water content of different materials is also different, if the humidity value of direct detection clothing this moment, the humidity value difference that obtains of different positions of detection is great, causes the misjudgement easily. In the embodiment of the application, the heating device of the drying equipment is started firstly to pre-dry the clothes. In the pre-drying process, the clothes dryer controls the clothes in the drum to roll continuously, so that the humidity difference of different positions of the clothes can be reduced, and the humidity judgment accuracy can be greatly improved.

Step S102, a first drying time length is obtained.

Here, the first drying time period is a time period for pre-drying the object to be dried. After drying starts, a timer is started to start timing so as to obtain a first drying time length.

Step S103, detecting the humidity of the inner cylinder of the drying equipment to obtain a first humidity value under the condition that the first drying time reaches a first time threshold.

The first time threshold is a preset pre-drying time. Generally, different materials and different amounts of clothes to be dried have different pre-drying time lengths when the humidity difference of different positions of the clothes to be dried is reduced to be within an error range. Through experiments, after most of the clothes are pre-dried for 3 to 5 minutes, the humidity difference of different positions of the clothes can be reduced to be within an error range, and based on the error range, the first time threshold value can be set to be 3 to 5 minutes, for example, 3 minutes.

After the clothes in the drum are pre-dried for 3 minutes by the clothes dryer, the detection device positioned in the drum detects the humidity of the inner drum of the clothes dryer to obtain a first humidity value. Here, when laundry to be dried exists in the drum of the dryer, the humidity of the inner drum is the humidity of the surface of the laundry to be dried. When the clothes to be dried do not exist in the clothes dryer cylinder, two conditions exist, one condition is that the clothes do not exist in the clothes dryer cylinder, namely the clothes dryer cylinder is an empty cylinder, and the humidity of the inner cylinder is the humidity of the air in the cylinder; another situation is that clothes exist in the drum of the clothes dryer, but the clothes are dried clothes, that is, undried clothes do not exist, and the humidity of the inner drum is the humidity of the surface of the dried clothes in the drum.

In the embodiment of the application, the detection device for detecting the humidity of the inner cylinder of the drying equipment can be a humidity sensor, and the humidity sensor can be arranged on the side wall of the inner cylinder of the drying equipment.

Step S104, determining the load grade of the drying equipment based on the first humidity value.

In practice, when the clothes to be dried are more, the humidity of the inner drum is still higher after the clothes are pre-dried for 3 minutes; when the clothes to be dried are less, after the clothes are pre-dried for 3 minutes, the humidity of the inner drum is relatively low; when there is no laundry to be dried (the drum is empty or the laundry to be dried has been dried), the drum humidity is less than the drying humidity threshold, and thus, the load level of the drying apparatus can be determined according to the magnitude of the first humidity value.

In an embodiment of the present application, the load of the drying apparatus may be classified into a first load class, a second load class, a third load class, and a fourth load class based on the first humidity value.

And step S105, determining a time compensating duration threshold of the object to be dried based on the load grade.

And after the load grade of the drying equipment is determined, further determining a time-compensating time length threshold of the object to be dried according to the load grade. When the clothes to be dried are more, supplementing time and drying the clothes to be dried for a longer time; when the clothes to be dried are less, supplementing time and drying for the clothes to be dried for a short time; when the clothes to be dried do not exist, the clothes do not need to be subjected to time-adding drying, namely, the time-adding duration threshold of the objects to be dried can be determined to be 0.

And step S106, continuing to dry the object to be dried based on the time compensation time length threshold.

And after the load grade of the drying equipment is determined, continuously drying the clothes to be dried based on the time-compensating time length threshold. For example, when it is determined that the load level of the drying device is small, that is, the amount of the laundry to be dried is small, the laundry to be dried is continuously dried for a short time, so that the laundry to be dried is prevented from being excessively dried, and damage to the laundry is avoided. When the load grade of the drying equipment is determined to be larger, namely the amount of the clothes to be dried is larger, the clothes to be dried are continuously dried for a longer time, so that the phenomenon that the clothes to be dried are not dried can be avoided, and the drying effect is ensured.

According to the drying method provided by the embodiment of the application, the drying equipment is determined to enter a drying stage, and a heating device of the drying equipment is started to dry an object to be dried; acquiring first drying time, and detecting the humidity of an inner barrel of the drying equipment to acquire a first humidity value under the condition that the first drying time reaches a first time threshold; determining a load level of the drying apparatus based on the first humidity value; and determining a time-compensating time length threshold of the object to be dried based on the load grade, and continuously drying the object to be dried based on the time-compensating time length threshold. The humidity value is detected after the object to be dried is pre-dried, the load grade size is determined based on the humidity value, the accuracy of the determined load grade can be improved, the time length during the time compensation in the drying process is controlled based on the load grade, the drying efficiency can be improved, the phenomenon that the object to be dried is excessively dried or not dried can be avoided, and the drying effect is guaranteed.

In some embodiments, the "determining the load level of the drying apparatus based on the first humidity value" in step S104 of the embodiment shown in fig. 1 may be implemented as the steps of:

step S104a1, determining whether the first humidity value is greater than a first humidity threshold.

When the first humidity value is larger than the first humidity threshold value, indicating that the object to be dried exists in the inner drum of the drying equipment, and entering the step S104a 2; when the first humidity value is less than or equal to the first humidity threshold, the process proceeds to step S104a 3.

Step S104a2, determining whether the first humidity value is less than a second humidity threshold.

When the first humidity value is smaller than the second humidity threshold, indicating that the humidity value of the laundry to be dried in the dryer is relatively small after the pre-drying, then the step S104a4 is entered; when the first humidity value is greater than or equal to the second humidity threshold, which indicates that the humidity of the laundry to be dried in the dryer is relatively large after the pre-drying, the flow proceeds to step S104a 5.

Here, the first humidity threshold is less than the second humidity threshold. For example, if the first humidity threshold is 1600 and the second humidity threshold is 4000, the first humidity value is greater than or equal to 1600 and less than 4000.

Step S104a3, determining the load level of the drying apparatus as a first load level.

Step S104a4, determining the load level of the drying apparatus as a second load level.

Step S104a5, determining the load level of the drying apparatus as a third load level.

Wherein the second load level is greater than the first load level and the second load level is less than the third load level.

When the first humidity value is less than or equal to 1600, determining that the load grade of the drying equipment is a first load grade, namely determining that the clothes to be dried do not exist in the drum; when the first humidity value is larger than 1600 and smaller than 4000, the load grade of the drying device is determined to be the second load grade, namely, the drum is determined to have less clothes to be dried. And when the first humidity value is more than or equal to 4000, determining that the load grade of the drying equipment is a third load grade, namely determining that more clothes to be dried exist in the drum.

In another implementation, in order to more accurately determine the load level of the drying apparatus, when the first humidity value is greater than or equal to 4000, the load level may be further subdivided. At this time, "determining the load level of the drying apparatus based on the first humidity value" in step S104 of the embodiment shown in fig. 1 may be implemented as the following steps:

step S104b1, determining whether the first humidity value is greater than a first humidity threshold.

When the first humidity value is larger than the first humidity threshold value, indicating that the object to be dried exists in the inner drum of the drying equipment, and entering step S104b 2; when the first humidity value is less than or equal to the first humidity threshold, the process proceeds to step S104b 3.

Step S104b2, determining whether the first humidity value is less than a second humidity threshold.

When the first humidity value is smaller than the second humidity threshold, indicating that the humidity value of the laundry to be dried in the dryer is relatively small after the pre-drying, then the step S104b4 is entered; when the first humidity value is greater than or equal to the second humidity threshold, which indicates that the humidity of the laundry to be dried in the dryer is relatively large after the pre-drying, the operation proceeds to step S104b 5.

Step S104b3, determining the load level of the drying apparatus as a first load level.

And step S104b4, determining the load level of the drying equipment as a second load level.

When the first humidity value is less than or equal to 1600, determining that the load grade of the drying equipment is a first load grade, namely determining that the clothes to be dried do not exist in the drum; when the first humidity value is larger than 1600 and smaller than 4000, the load grade of the drying apparatus is determined as a second load grade, that is, it is determined that there is less laundry to be dried in the drum.

And step S104b5, drying the object to be dried continuously.

When the first humidity value is greater than or equal to 4000, the drying of the laundry is continued in order to further subdivide the load class.

Step S104b6, a second drying time period is acquired.

In one implementation, the second drying time period is a time period for performing secondary pre-drying on the object to be dried. And starting a timer to start timing to acquire a second drying time period after the first humidity value is determined to be more than or equal to 4000.

In another implementation manner, the second drying time period is a total time period for drying the object to be dried after the drying starts. After drying is started, a timer is started to start timing so as to obtain a second drying time length.

Step S104b7, determining whether the second drying time period reaches a second time period threshold.

When the second drying time reaches the second time threshold, indicating that the secondary pre-drying is finished, and entering step S104b8 to detect the humidity of the inner drum again; when the second drying time period does not reach the second time period threshold, returning to step S104b5 to continue the secondary pre-drying.

In a first implementation of step S104b6, the second duration threshold may be set to 3 to 5 minutes, for example 5 minutes.

In a second implementation of step S104b6, the second duration threshold may be set to 6 to 10 minutes, for example 8 minutes.

And step S104b8, detecting the humidity of the inner barrel to acquire a second humidity value.

Here, the obtained second humidity value is the humidity of the surface of the laundry to be dried currently.

Step S104b9, determining whether the second humidity value is less than the second humidity threshold.

When the second humidity value is smaller than the second humidity threshold, indicating that the humidity value of the laundry to be dried in the dryer is smaller after the secondary pre-drying, then step S104b10 is performed; when the second humidity value is greater than or equal to the second humidity threshold, indicating that the humidity of the laundry to be dried in the dryer is still relatively high after the secondary pre-drying, the process proceeds to step S104b 11.

And step S104b10, determining the load level of the drying equipment as a third load level.

Here, the third load level is greater than the second load level.

And on the premise that the first humidity value is more than or equal to 4000, when the second humidity value is less than 4000, determining that the load grade of the drying equipment is a third load grade, namely determining that the middle amount of clothes to be dried exist in the drum.

And step S104b11, determining the load grade of the drying equipment as a fourth load grade.

Here, the fourth load level is greater than the third load level.

And when the second humidity value is larger than or equal to 4000, determining that the load grade of the drying equipment is a fourth load grade, namely determining that more clothes to be dried exist in the drum.

In the embodiment of the application, when the first humidity value is greater than or equal to the second humidity threshold, the object to be dried is subjected to secondary pre-drying, and then whether the second humidity value is greater than the second humidity threshold is judged, so that the load level of the drying equipment can be determined more accurately.

In some embodiments, the step S105 "determining the time-complementing duration threshold value of the object to be dried based on the load level" of the embodiment shown in fig. 1 may be implemented as the following steps:

step S1051, determining that the time compensation duration threshold is a first time compensation threshold when the load level is a first load level.

When the humidity value of the object to be dried reaches the first humidity threshold, if the load level of the drying device is the first load level, the first time-complementing threshold is continuously dried.

After the inner drum of the clothes dryer is pre-dried for 3 minutes, if the humidity of the inner drum is detected to be smaller than a first humidity threshold value, at the moment, the load level of the drying equipment is determined to be a first load level, namely, clothes do not exist in the inner drum of the clothes dryer, or only dried clothes exist in the clothes dryer, namely, objects to be dried which need to be dried continuously do not exist, at the moment, the drying stage is finished, and the electric energy consumption caused by drying the empty drum is avoided.

Step S1052, determining that the time-complementing duration threshold is a second time-complementing threshold when the load level is a second load level.

Step S1053, determining that the time-compensating duration threshold is a third time-compensating threshold when the load level is a third load level.

Step S1054, when the load level is a fourth load level, determining that the time compensation duration threshold is a fourth time compensation threshold.

When the load of the drying equipment is less, the drying and time supplementing are carried out for a short time, and the clothes are ensured not to be damaged on the premise of drying the clothes; when the load of the drying equipment is more, the drying is carried out for a longer time, the clothes are ensured to be dried, and the drying effect is ensured.

In some embodiments, the step S106 "continuing to dry the object to be dried based on the complementary time duration threshold" in the embodiment shown in fig. 1 may be implemented as the following steps:

and step S1061, continuing to dry the object to be dried.

Step S1062, detecting the humidity of the inner cylinder to obtain a third humidity value.

Here, the obtained third humidity value is the humidity of the surface of the laundry to be dried currently.

Step S1063, determining whether the third humidity value is smaller than the first humidity threshold.

When the third humidity value is smaller than the first humidity threshold value, indicating that the clothes to be dried are dried, and then entering step S1064 for drying and supplementing; when the third humidity value is greater than or equal to the first humidity threshold value, it indicates that the laundry to be dried has not been dried, and the step returns to step S1061 to continue drying.

And step S1064, performing time-supplementing drying on the object to be dried until the time-supplementing drying time reaches the time-supplementing time threshold.

If the load grade of the drying equipment is a second load grade, continuing to dry a second time-supplementing threshold; if the load grade of the drying equipment is a third load grade, continuing to dry a third time-supplementing threshold; and if the load grade of the drying equipment is the fourth load grade, continuing drying the fourth time-supplementing threshold value.

In the embodiment of the application, when the humidity in the drum is detected to reach the first humidity threshold value, the time-adding drying is carried out on the dried clothes in order to improve the drying effect. When the time compensation drying is performed, different time compensation durations are determined according to the load grade in the embodiment of the application, and the clothes can not be damaged on the premise of improving the drying effect.

In some embodiments, after determining that there is no object to be dried which needs to be continuously dried in step S106, or after determining that the object to be dried continues to be dried in step S1064 for a time-complementing period threshold, the method may further include:

step S107, turning off the heating device.

And step S108, finishing the drying stage.

After the drying stage is finished, cold air can be further blown into the inner cylinder of the clothes dryer to reduce the temperature of clothes and avoid the skin of a user from being damaged by high temperature when a door body of the clothes dryer is opened.

The clothes drying machine in the market at present adopts two humidity detection methods, one is to adopt manual humidity detection, the humidity of clothes is judged by a user independently, and the power is controlled by selecting a function key on a panel, so that the clothes are dried. The mode has manual selection errors, and if the power is not properly selected, the clothes are easy to be dried or overdried. The other method is to use a humidity sensor to judge the load and then dry according to the load. Because the humidity is great when clothing is initial, and its water content of different materials is also different, leads to the misjudgement easily. The method for drying the clothes only has good drying effect on some small loads, but has the defects that the outer surfaces of the clothes are dry, the inner parts of the clothes are still wet and misjudgment exists on the large-load clothes such as quilts, four-piece sets and the like, so that the clothes are not dried, and the drying effect is poor.

The method not only avoids errors caused by manual power selection, reduces the phenomenon of overdrying or undrying, but also can judge the size of the load more accurately, determines the drying time compensation time according to the load, greatly improves the humidity judgment precision and improves the drying efficiency.
