[0039] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0041] As people's living standards continue to improve, clothes dryers are receiving more and more attention and love from people, and the popularity and usage rate of clothes dryers have greatly increased. As the number of clothes dryer users increases, more problems with clothes dryers are exposed. Among them, the drying time of clothes dryers has always been a pain point for users. Sometimes it takes 1-2 hours or even longer to dry a few pieces of clothes. In addition, clothes dryers also have the problem of uneven drying. For example, clothes taken out of the dryer are dry in some places and a little damp in some places, which leads to a poor user experience.

[0042] In order to solve the above-mentioned technical problems, the embodiment of the present disclosure provides a drying control method for a clothes dryer. In the process of drying clothes by the clothes dryer, by obtaining the humidity in the clothes dryer drum, that is, the humidity threshold, the humidity interval of the humidity in the clothes dryer drum can be determined according to the humidity threshold, and then the drying speed of the clothes dryer drum corresponding to the humidity interval is controlled according to the humidity interval. When the humidity threshold is larger, the drying speed of the clothes dryer is increased, which is conducive to shortening the drying time of the clothes dryer; when the humidity threshold is smaller, the drying speed of the clothes dryer is reduced, which is conducive to avoiding the problem of uneven drying of clothes by the clothes dryer due to excessively fast positive rotation speed. Therefore, while accelerating the drying of clothes, the problem of uneven drying of clothes by the clothes dryer can also be avoided, the drying time and drying effect of the clothes dryer are optimized, and the user experience is improved.

[0043] The following is combined with Figures 1 to 4The drying control method and device of a clothes dryer and the clothes dryer provided in the embodiments of the present disclosure are exemplarily described.

[0044] Figure 1 The present invention provides a flowchart of a drying control method for a clothes dryer. The method is applicable to application scenarios where the drying process of the clothes dryer needs to be controlled. The method can be executed by a drying control device for a clothes dryer provided in the present invention, and the drying control device for the clothes dryer can be implemented in software and / or hardware. Figure 1 As shown, the method comprises the following steps:

[0045] S101, obtaining the humidity in the dryer drum during the drying process.

[0046] Specifically, a humidity detection component is installed in the dryer, such as but not limited to a humidity sensor, and the humidity in the dryer barrel is detected by the humidity sensor. The humidity sensor can be set to detect the humidity in the dryer barrel in real time, and then obtain the humidity in the dryer barrel; the humidity sensor can also be set to detect at a certain frequency, for example, to detect the humidity in the dryer barrel once within a preset interval, and then obtain the humidity in the dryer barrel. Compared with real-time detection, detection within a preset interval can reduce the power consumption of the humidity sensor. Therefore, after the dryer starts the drying program, the humidity in the dryer barrel is detected by the humidity detection component, and then the humidity in the dryer barrel is obtained.

[0047] In other embodiments, other technical means well known to those skilled in the art may be used to obtain the humidity in the dryer drum, which will not be specifically limited or elaborated herein.

[0048] In some embodiments, obtaining the humidity in the dryer drum during the drying process includes obtaining the humidity of clothes in the dryer drum during the drying process as the humidity in the dryer drum; or obtaining the humidity of air in the dryer drum during the drying process as the humidity in the dryer drum.

[0049] Specifically, after the dryer starts the drying program, the dryer can dry the wet clothes in the dryer drum. At this time, the humidity on the surface of the wet clothes in the dryer drum can be detected by the humidity detection component, and then the humidity of the clothes in the dryer drum can be obtained. The humidity of the clothes to be dried is directly used as the humidity in the dryer drum, and the user makes subsequent humidity range judgments.

[0050] Alternatively, after the dryer starts the drying program, the dryer can dry the wet clothes in the dryer drum. At this time, the humidity of the air in the dryer drum can be detected by the humidity detection component, and then the humidity of the air in the dryer drum can be obtained. The humidity of the air in the dryer drum is directly used as the humidity in the dryer drum for subsequent humidity range judgment.

[0051] Alternatively, after the dryer starts the drying program, the dryer can dry the wet clothes in the dryer drum. At this time, the humidity of the air in the dryer drum can be detected by the humidity detection component, and the humidity on the surface of the wet clothes in the dryer drum can be detected by the humidity detection component. The average value of the humidity of the air in the dryer drum and the humidity on the surface of the wet clothes in the dryer drum can be used as the humidity in the dryer drum for subsequent humidity range judgment.

[0052] It should be noted that, for the humidity in the dryer drum at the same moment, the humidity threshold obtained by detecting the humidity of the clothes in the dryer drum is, for example, H, and the humidity threshold obtained by detecting the humidity of the air in the dryer drum is, for example, N. The values ​​of the humidity threshold H and the humidity threshold N are different. Accordingly, the humidity zone subsequently used to adjust the forward drying speed of the dryer can also be adjusted to adapt to different humidity detection methods.

[0053] S102, controlling the forward rotation speed of the dryer drum according to the humidity range in which the humidity is located; wherein the humidity threshold corresponding to the humidity range is proportional to the forward rotation speed.

[0054] Specifically, the humidity can be divided into multiple humidity intervals according to a preset humidity threshold, that is, different humidity intervals correspond to different humidity thresholds, and thus based on the humidity information in the dryer drum obtained in S101, the humidity thresholds corresponding to different humidity intervals are obtained, and the humidity interval in which the humidity in the dryer drum is located can be determined according to the preset humidity threshold, and then the forward rotation speed of the dryer is controlled according to the humidity interval in which the humidity is located, that is, the forward rotation speed of the dryer is controlled according to the humidity threshold corresponding to the humidity interval. Among them, when the humidity threshold corresponding to the humidity interval is larger, the forward rotation speed of the dryer is larger; when the humidity threshold corresponding to the humidity interval is smaller, the forward rotation speed of the dryer is smaller.

[0055] Exemplarily, three preset humidity thresholds are set to divide the humidity into four humidity intervals. Specifically, a first humidity preset threshold H1, a second humidity preset threshold H2, and a third humidity preset threshold H3 are set, and the first humidity preset threshold H1, the second humidity preset threshold H2, and the third humidity preset threshold H3 are successively reduced, so that the above three humidity thresholds can divide the humidity into four humidity intervals.

[0056] The first humidity preset threshold H1 is set to, for example but not limited to, 80%RH, the second humidity preset threshold H2 is set to, for example but not limited to, 60%RH, and the third humidity preset threshold H3 is set to, for example but not limited to, 30%RH. Thus, according to the first humidity preset threshold 80%RH, the second humidity preset threshold 60%RH, and the third humidity preset threshold 30%RH, the humidity can be divided into four humidity intervals, namely, the first humidity interval, the second humidity interval, the third humidity interval, and the fourth humidity interval. The first humidity interval can be a humidity threshold greater than the first humidity preset threshold 80%RH; the second humidity interval can be a humidity threshold greater than the second humidity preset threshold 60%RH and less than the first humidity preset threshold 80%RH; the third humidity interval can be a humidity threshold greater than the third humidity preset threshold 30%RH and less than the second humidity preset threshold 60%RH; the fourth humidity interval can be a humidity threshold less than the third humidity preset threshold 30%RH.

[0057] Thus, according to the detected humidity in the dryer drum, and judging the humidity interval in which the detected humidity is located, when it is judged that the humidity of the current dryer drum is in the first humidity interval, the humidity threshold is relatively large at this time, and the forward rotation speed of the dryer drum can be increased, and the dryer drum is controlled to run at the forward rotation speed r1, r1 is, for example, but not limited to 100-90 rpm; when it is judged that the humidity of the current dryer drum is in the second humidity interval, the dryer drum is controlled to run at the forward rotation speed r2, r2 is, for example, but not limited to 90-80 rpm; when it is judged that the humidity of the current dryer drum is in the third humidity interval, the dryer drum is controlled to run at the forward rotation speed r3, r3 is, for example, but not limited to 70-80 rpm; when it is judged that the humidity of the current dryer drum is in the fourth humidity interval, the humidity threshold is relatively small at this time, and the forward rotation speed of the dryer drum is reduced, and the dryer drum is controlled to run at the forward rotation speed r4, r4 is, for example, but not limited to 50-70 rpm.

[0058] It should be noted that the above embodiment only illustrates that the humidity threshold can divide the humidity into four humidity intervals, and two humidity thresholds can be set to divide the humidity into three humidity intervals, and four humidity thresholds can be set to divide the humidity into five humidity intervals. The present embodiment does not specifically limit this. In addition, the present embodiment does not limit the specific correspondence between the humidity area and the forward speed.

[0059] The drying control method for a clothes dryer provided in the embodiment of the present disclosure, during the process of the dryer drying the clothes to be dried in the dryer drum, by obtaining the humidity in the dryer drum, that is, the humidity threshold, the humidity interval in which the humidity in the dryer drum is located can be determined according to the humidity threshold, and then the drying speed of the clothes dryer corresponding to the humidity interval is controlled according to the humidity interval, when the humidity threshold corresponding to the humidity interval is larger, the drying speed of the clothes dryer is increased, which is helpful to shorten the drying time of the clothes dryer; when the humidity threshold corresponding to the humidity interval is smaller, the drying speed of the clothes dryer is reduced, which is helpful to avoid the problem of uneven drying caused by the clothes to be dried sticking to the wall of the dryer drum due to the excessively fast drying speed.

[0060] Therefore, while accelerating the drying of the clothes to be dried in the dryer drum, the problem of uneven drying of the clothes to be dried by the dryer can also be avoided, thereby optimizing the drying time and drying effect of the dryer, thereby improving the user experience.

[0061] In some embodiments, the drying control method of the clothes dryer further includes:

[0062] During the process of switching the forward rotation speed of the dryer drum, the dryer drum is controlled to stop rotating for a first preset time period.

[0063] Specifically, when the dryer dries the clothes to be dried, as the drying process proceeds, the lower the moisture content of the clothes in the dryer drum, that is, the lower the humidity threshold corresponding to the humidity in the dryer drum. Based on the detected humidity in the dryer drum, when it is determined that the humidity in the dryer drum is converted from, for example, in the first humidity interval to the second humidity interval, the forward speed of the dryer is switched, for example, the rotation speed of the dryer drum is switched from 100-90 rpm to 90-80 rpm. When the forward speed of the dryer drum is switched, in order to avoid the belt in the dryer slipping due to the direct switching of the rotation speed, which affects the drying process of the dryer, the dryer drum is controlled to stop for a first preset time, for example, 3-5 seconds, which is conducive to preventing the belt of the dryer drum from slipping.

[0064] Therefore, when it is necessary to switch the forward rotation speed of the dryer, the embodiment of the present disclosure controls the dryer drum to stop for a period of time. After the dryer drum stops for a period of time, the rotation speed of the dryer drum is switched, which is helpful to prevent the belt in the dryer from slipping, thereby avoiding the problem of the drying process of the dryer being affected by the slipping of the belt in the dryer.

[0065] In some embodiments, after controlling the clothes dryer drum to stop for a first preset time, the method further includes:

[0066] Controls the dryer drum to reverse for a second preset time.

[0067] Specifically, as the drying process in the dryer proceeds, some clothes in the dryer drum have been dried, while some clothes are still wet. At this time, it is easy for the partially dried large clothes to wrap the undried small clothes, and the clothes to be dried are easy to stick to the wall of the dryer drum, which leads to the problem of uneven drying of the clothes in the dryer drum.

[0068] In order to solve the problem of uneven drying of clothes by the dryer, after the dryer drum stops for a first preset time, the dryer is controlled to reverse for a second preset time, for example 10-20 seconds. During the reversal period, the clothes in the dryer drum are shaken out, which is beneficial to optimize the dryer's drying uniformity of the clothes.

[0069] After the dryer reverses for the second preset time, the dryer drum can continue to be stopped for the first preset time, and then the forward speed of the dryer drum is switched, which can achieve the shaking of the clothes in the dryer drum and optimize the drying uniformity of the clothes by the dryer, and prevent the belt in the dryer from slipping. The reverse drying speed of the dryer drum can be, for example, but not limited to, 50-60 rpm.

[0070] It should be noted that controlling the dryer drum to reverse is not limited to after the dryer drum stops rotating for the first preset time. When the dryer is in normal operation, in order to prevent the clothes to be dried from sticking to the wall of the dryer drum and affecting the uniform drying of the clothes, the dryer drum can be controlled to reverse every 10 minutes or every 15 minutes.

[0071] In some embodiments, the drying control method of the clothes dryer further includes:

[0072] The duration for which the dryer drum runs at the first forward rotation speed is controlled to be greater than the duration for which the dryer drum runs at the second forward rotation speed; wherein the first forward rotation speed is greater than the second forward rotation speed.

[0073] Specifically, respectively controlling the length of time the dryer drum runs at a high drying speed and the length of time the dryer drum runs at a low drying speed may include increasing the length of time the dryer runs at a high drying speed, i.e., a first forward rotation speed, and decreasing the length of time the dryer runs at a low drying speed, i.e., a second forward rotation speed.

[0074] Therefore, when the clothes dryer is operated at a high drying speed, its operating time is increased, which is beneficial to speed up the drying of the clothes in the clothes dryer and further shorten the drying time of the clothes to be dried.

[0075] In some embodiments, the drying control method of the clothes dryer further includes:

[0076] During the drying process, the preset interval controls the dryer drum to reverse and shake out for a third preset time;

[0077] The number of reverse shaking of the dryer drum during operation at the third forward speed is controlled to be less than the number of reverse shaking of the dryer drum during operation at the fourth forward speed; wherein the third forward speed is greater than the fourth forward speed.

[0078] Specifically, when the dryer is in normal operation, in order to prevent the clothes to be dried from sticking to the wall of the dryer drum and affecting the uniform drying of the clothes, the dryer is controlled to reverse once at preset intervals, such as every 10 minutes or every 15 minutes, to shake out the clothes in the dryer drum.

[0079] Specifically, when it is determined that the corresponding humidity threshold in the dryer drum is larger, the clothes in the dryer drum are relatively humid at this time, and the dryer drum is controlled to operate at a high drying speed. Since the clothes in the dryer drum are relatively humid, even when the dryer drum operates at a high drying speed, the clothes to be dried in the dryer drum stick to the wall of the dryer drum, which has little effect on the drying effect of the clothes and can reduce the number of reversals in the high-speed operation stage of the dryer drum.

[0080] However, when it is determined that the corresponding humidity threshold in the dryer drum is small, that is, most of the clothes to be dried in the dryer drum have been dried, and only a small part of the clothes are undried, the dryer drum operates at a low drying speed. At this time, some clothes to be dried in the dryer drum are attached to the wall of the dryer drum, which may easily cause uneven drying of the clothes in the dryer drum. Therefore, the number of reversals in the low-speed operation stage of the dryer drum can be increased, which can improve the problem of uneven drying of clothes and help optimize the drying effect of the dryer.

[0081] Therefore, when the third forward speed of the dryer is greater than the fourth forward speed, the number of reverse shaking times of the dryer at the high drying speed, i.e. the third forward speed, and the number of reverse shaking times of the dryer at the low drying speed, i.e. the fourth forward speed, are controlled respectively. By increasing the number of reverse shaking times of the dryer at the fourth forward speed, i.e. the low drying speed, it is helpful to improve the problem of uneven drying of clothes, thereby optimizing the drying effect of the dryer.

[0082] In some embodiments, before controlling the forward rotation speed of the clothes drying machine drum according to the humidity interval, the method further includes:

[0083] Obtain the weight of the clothes to be dried in the dryer drum;

[0084] The humidity threshold corresponding to the humidity interval is dynamically adjusted according to the weight of the clothes to be dried; wherein the humidity threshold is proportional to the weight.

[0085] Specifically, when the dryer is in the drying process, the weight of the clothes to be dried in the dryer drum is obtained. The heavier the weight of the clothes to be dried, the more clothes there are in the dryer drum. Since there are more clothes in the dryer drum, the humidity in the dryer drum decreases relatively slowly during the drying process. At this time, the humidity threshold corresponding to the humidity interval can be dynamically adjusted, for example, the humidity threshold corresponding to the humidity interval can be increased. Similarly, when the weight of the clothes to be dried is lighter, it indicates that there are fewer clothes in the dryer drum. Since there are fewer clothes in the dryer drum, the humidity in the dryer drum decreases relatively quickly during the drying process. At this time, the humidity threshold corresponding to the humidity interval can be dynamically adjusted, for example, the humidity threshold corresponding to the humidity interval can be lowered.

[0086] Therefore, the forward rotation speed of the dryer is controlled according to the corresponding humidity threshold, which improves the intelligence level of the drying process of the dryer and also improves the accuracy of adjusting the forward rotation drying speed of the dryer drum according to the humidity.

[0087] When the weight of the clothes to be dried in the dryer drum increases, the humidity threshold corresponding to the humidity interval is dynamically increased. For example, compared with the humidity preset threshold setting of the aforementioned embodiment example, after the clothes increase, the first humidity preset threshold H1 can be set to, for example but not limited to, 90%RH, the second humidity preset threshold H2 can be set to, for example but not limited to, 70%RH, and the third humidity preset threshold H3 can be set to, for example but not limited to, 40%RH, so that the humidity can be re-divided into four humidity intervals according to the first humidity preset threshold 90%RH, the second humidity preset threshold 70%RH, and the third humidity preset threshold 40%RH. For example, the adjusted first humidity interval can be a humidity threshold greater than the first humidity preset threshold 90%RH; the adjusted second humidity interval can be greater than the second humidity preset threshold 70%RH and less than the first humidity preset threshold 90%RH; the adjusted third humidity interval can be a humidity threshold greater than the third humidity preset threshold 40%RH and less than the second humidity preset threshold 70%RH; the adjusted fourth humidity interval can be a humidity threshold less than the third humidity preset threshold 40%RH.

[0088] Before controlling the forward rotation speed of the dryer drum according to the humidity range, the method further includes:

[0089] Obtain the weight of the clothes to be dried in the dryer drum;

[0090] Control the preset operating parameters of the dryer drum corresponding to the first weight of the clothes to be dried to be greater than the preset operating parameters of the dryer drum corresponding to the second weight of the clothes to be dried; wherein the preset operating parameters include the forward speed and / or the forward drying time, and the first weight of the clothes to be dried is greater than the second weight of the clothes to be dried.

[0091] Specifically, when the clothes dryer is in the drying process, the weight of the clothes to be dried in the clothes dryer drum is obtained, and the preset operating parameters of the clothes dryer drum are controlled according to the weight of the clothes to be dried. When the weight of the clothes to be dried in the clothes dryer drum is heavy, the preset operating parameters of the clothes dryer drum are increased; when the weight of the clothes to be dried in the clothes dryer drum is light, the preset operating parameters of the clothes dryer drum are reduced.

[0092] Among them, the preset operating parameters include forward rotation speed and / or forward rotation drying time, and controlling the preset operating parameters of the dryer drum means only controlling the forward rotation speed of the dryer drum, or only controlling the forward rotation drying time of the dryer drum, or controlling the forward rotation speed and forward rotation drying time of the dryer drum.

[0093] For example, the weights of the clothes to be dried are m1 and m2, and m1 is greater than m2. When the drying program of the clothes dryer is turned on, and the clothes with a weight of m1 and the clothes with a weight of m2 are dried respectively, the drying speed of the clothes with a weight of m1 can be controlled to be greater than the drying speed of the clothes with a weight of m2; or the drying time of the clothes with a weight of m1 can be controlled to be greater than the drying time of the clothes with a weight of m2; or the drying speed and drying time of the clothes with a weight of m1 can be controlled to be greater than the drying speed and drying time of the clothes with a weight of m2.

[0094] Therefore, when there are more clothes to be dried in the dryer drum, that is, the weight of the clothes to be dried in the dryer drum is heavier, increasing the forward rotation speed and / or forward drying time of the dryer drum is beneficial to speed up the drying speed of the clothes to be dried, thereby shortening the drying time and improving the user experience.

[0095] Based on the above embodiments, Figure 2 The specific flow chart of a drying control method of a clothes dryer provided by an embodiment of the present disclosure is exemplarily shown. The method can also be executed by the drying control device of the clothes dryer provided by an embodiment of the present disclosure. Figure 2 As shown, the method comprises the following steps:

[0096] S201, program running.

[0097] S202: Determine whether the humidity in the clothes dryer drum is less than a first humidity threshold H1. If so, execute S204; if not, execute S203.

[0098] S203, controlling the dryer drum to run at a speed of r1.

[0099] S204: Determine whether the humidity in the dryer drum is less than a second humidity threshold H2. If so, execute S206; if not, execute S205.

[0100] S205, controlling the dryer drum to run at a speed of r2.

[0101] S206: Determine whether the humidity in the dryer drum is less than a third humidity threshold H3. If so, execute S208; if not, execute S207.

[0102] S207, controlling the clothes dryer drum to run at a speed of r3.

[0103] S208, controlling the dryer drum to run at a speed of r4.

[0104] S209, end.

[0105] It should be noted that the steps of the above method can be executed once every 100 milliseconds.

[0106] The drying control method for a dryer provided in an embodiment of the present disclosure, during the process of the dryer drying the clothes to be dried in the dryer drum, by obtaining the humidity in the dryer drum, that is, the humidity threshold, the humidity range in which the humidity in the dryer drum is located can be determined according to the humidity threshold, and then the forward rotation speed of the dryer drum corresponding to the humidity range is controlled according to the humidity range, when the humidity threshold corresponding to the humidity range is larger, the forward rotation speed of the dryer drum is increased; when the humidity threshold corresponding to the humidity range is smaller, the forward rotation speed of the dryer drum is reduced.

[0107] Therefore, when the dryer is in the early stage of drying, the clothes to be dried in the dryer barrel are relatively moist. At this time, the humidity threshold in the dryer drum is relatively high, which increases the drying speed of the dryer drum, thereby increasing the air volume in the dryer drum, which is beneficial to speeding up the drying speed of the dryer; as the drying program runs at any time, the humidity in the barrel of the dryer drum gradually decreases, that is, the humidity threshold in the dryer drum gradually becomes lower. At this time, the forward rotation speed of the dryer drum is gradually reduced, which can avoid the problem of clothes to be dried sticking to the wall of the dryer drum due to excessively high forward rotation speed of the dryer drum, thereby affecting the uniform drying of the clothes to be dried.

[0108] Therefore, the method provided by the embodiment of the present disclosure can accelerate the drying of the clothes to be dried in the dryer drum while avoiding the problem of uneven drying of the clothes to be dried by the dryer, optimize the drying time and drying effect of the dryer, and thus improve the user experience.
