[0011] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0012] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art belonging to the technical field of the present application. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application. The terms "first", "second", "third", "fourth", etc. (if present) in the specification of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order.

[0013] In addition, the described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the present disclosure.

[0014] With the rapid development of smart homes and the improvement of quality of life, related technologies have proposed devices with built-in drying functions, such as drying hangers and dryers. However, most of the existing drying devices adopt a drying strategy of timed drying or manual start and stop of drying. The former cannot take into account both energy consumption and drying effect, and the latter cannot take into account both energy consumption and ease of use. Based on this, although automatic drying strategies are also proposed in related technologies, due to the uncertainty of environmental factors and the different types of items, the existing drying strategies are not accurate enough in identifying wet objects, resulting in only being able to start automatic drying for specific items, which is not convenient to use. Therefore, how to set a control method for a hanging device so that the automatic drying function of the hanging device is more universal. Based on this, the embodiment of the present application proposes a control method for a hanging device, a hanging device and a storage medium, aiming to make the automatic drying function of the hanging device more universal.

[0015] Understandably, referring to Figure 1 and Figure 2 As shown, a hanging device provided according to an embodiment of the present application includes: A clothes-drying main body 110, on which a wet object sensing area 111 is disposed, and on which a sensor array is disposed; The controller is connected to the air-drying main body 110, and the controller is in communication connection with each sensor 120 in the sensor array, and the controller executes: In response to the automatic drying request, preheating the air-drying main body 110 based on a preset power control algorithm within a first time period; Determine a humidity change amount by using a plurality of real-time humidity values ​​collected by the sensor array within a first period of time; According to the humidity change, the coverage status of the items in the wet object sensing area 111 is obtained; When the article covering state indicates the presence of wet articles, the hanging body 110 is heated at a preset first target power value until a preset heating stop condition is met.

[0016] It is understandable that the embodiment of the present application does not limit the structure of the hanging body 110, and those skilled in the art can selectively set it according to actual needs. Since the hanging device in the embodiment of the present application is based on the wet object sensing area, the hanging device can be designed as a smaller drying device such as a towel rack and a clothes drying rod. In some embodiments, the hanging body 110 can be configured to have two parallel rods. In other embodiments, the hanging body 110 can be configured as follows: Figure 1 A rod body is shown.

[0017] The wet object sensing area 111 represents the area covered by the objects hung on the hanging body 110. Those skilled in the art can selectively set it according to actual needs.

[0018] The sensor array is a collection of sensors 120 arranged evenly in equal rows and columns. The real-time humidity value corresponds to each sensor 120 in the sensor array. Using multiple sensors 120 to determine the humidity change can further improve the accuracy of humidity detection. For example, Figure 1 As shown, the sensor array includes 10 sensors 120 , and the 10 sensors are arranged in two rows and five columns on the wet object sensing area 111 of the drying and hanging body 110 .

[0019] The embodiment of the present application does not limit the connection method between the controller and each sensor 120 in the sensor array. For example, in some embodiments, the acquisition terminals of multiple sensors 120 are connected in parallel and connected to the controller through a unified interface. Figure 2 As shown, there are six sensors 120, namely U1 to U6; the acquisition terminals DO of the six sensors 120 are connected in parallel and connected to the controller via TP2. The embodiment of the present application does not limit the model of the sensor 120, for example, the sensor 120 is set to gxht3w.

[0020] There are two types of item covering status settings, one is when there are wet items, that is, automatic heating is required, and the other is when there are no items or dry items, that is, no automatic heating is required.

[0021] The power control algorithm is used to set the power corresponding to the humidity of the humid items within the first time period, which can be set according to actual needs. In some embodiments, the first target power is set to the maximum supported heating power, and in other embodiments, it is dynamically set according to the surrounding environmental factors, which is not limited in the embodiments of the present application.

[0022] It is understood that in some embodiments, Figure 1 As shown, the drying device further includes a digital display screen 200, on which a plurality of virtual buttons are displayed, the plurality of virtual buttons including a power button, an automatic drying mode button ( Figure 1 "A") and fixed drying time button ( Figure 1 The automatic drying mode button is used to automatically heat based on the automatic drying request when it is started, and the fixed-duration drying mode is 24 hours of continuous drying. In some embodiments, the digital display screen 200 also displays the humidity value collected in the wet object sensing area 111 in real time.

[0023] Understandably, referring to Figure 3 As shown, the sensor array is determined by the following steps: Obtaining the width value, length value and edge sensing reserved distance of the wet object sensing area 111; Determine the number of rows and the row spacing of the sensor array according to the width value; Determine the remaining arrangement length based on the edge sensing reserved distance and length value; Determine the number of columns and the column spacing of the sensor array according to the remaining arrangement length and the preset column arrangement interval range; The sensors 120 are arranged according to the number of rows, the row spacing, the number of columns and the column spacing to obtain a sensor array.

[0024] It is understandable that the edge sensing reserved distance represents the distance between the first row of sensors 120 and the boundary of the wet object sensing area 111. In some embodiments, the edge sensing reserved distance is smaller than the row spacing, so that the distance close to the wet object sensing area 111 in the sensor array is shorter, ensuring sufficient accuracy of edge detection.

[0025] A matching target column arrangement interval may be selected from the column arrangement interval range according to the remaining arrangement length, and the number of columns and the column spacing of the sensor array may be determined according to the target column arrangement interval.

[0026] For example, refer to Figure 3As shown, taking the range of the column arrangement interval as 60-90 mm as an example, assuming that the length of the wet object sensing area 111 is set to 380 mm, and the edge sensing reserved distance is set to 30 mm. According to the remaining arrangement length (380-30-30), it can be determined that the target column arrangement interval is 80 mm. At this time, 5 sensors 120 can be placed in the same row, and the first sensor 120 starts from the edge sensing reserved distance of the wet object sensing area 111, and is arranged every 80 mm.

[0027] In some embodiments, in the width direction, the number of rows and the row spacing are also determined according to the edge sensing reserved distance. For example, under the premise of ensuring that the distance from the boundary in the width direction is less than or equal to the edge sensing reserved distance, the number of rows and the row spacing are determined according to the width and the preset row arrangement spacing range. Exemplarily, taking the row arrangement spacing range being set to be less than or equal to 60 mm as an example, when the width is less than 60 mm, a row is set. When the width is set to 80 mm, 2 rows can be placed (wherein the row spacing can be set to 60 mm). For example, when the width is 100 mm, 3 rows can be placed (wherein the row spacing can be set to 60 mm or 50 mm).

[0028] Understandably, referring to Figure 4 As shown, according to a control method of a hanging device provided in an embodiment of the present application, the hanging device includes a hanging body 110, and a sensor array is provided on a wet object sensing area 111 of the hanging body 110. The control method includes: Step S100, in response to the automatic drying request, preheating the air-drying main body 110 based on a preset power control algorithm within a first time period; Step S200, determining a humidity change amount by using a plurality of real-time humidity values ​​collected by the sensor array within a first period of time; Step S300, obtaining the object coverage status of the wet object sensing area 111 according to the humidity change; Step S400: When the covering state of the articles indicates the presence of wet articles, the hanging body 110 is heated at a preset first target power value until a preset heating stop condition is met.

[0029] Therefore, the heating power of the air-drying main body 110 for preheating is controlled based on the preset power control algorithm within the first time period, and the humidity change (i.e., humidity change amount) caused by heating the air-drying main body 110 with the specified power defined in the power control algorithm within the first time period is determined. At this time, the judgment of the covering state of the article is based on the humidity change before and after heating. Compared with the judgment strategy of fixed temperature, the embodiment of the present application can adapt to the judgment of more different types of wet articles, has higher versatility and more accurate judgment of whether there are wet articles. Therefore, the embodiment of the present application can realize automatic drying of articles while improving the versatility of automatic drying of the air-drying device.

[0030] The automatic drying request in step S100 may be automatically triggered when the machine is turned on, or may be triggered when the machine enters the automatic drying mode after being turned on, or may be triggered based on the temperature and humidity values ​​of the sensor 120 to determine that the automatic drying conditions are met. In this regard, the embodiment of the present application does not limit how the automatic drying request is triggered. The first duration characterizes the duration of heating that can distinguish wet items. It can be determined based on experimental data measurements. The power control algorithm reflects the power set of heating powers that cause significantly different changes in humidity at different times within the first duration in the two cases of dry items / no items and wet items.

[0031] In step S200, each real-time humidity value corresponds to a sensor 120 in the sensor array. The humidity change represents the humidity value of the sensor array that increases or decreases after the first time period. In the case of multiple real-time humidity values, the change in the real-time humidity value of each sensor 120 can be calculated and then averaged, or the real-time humidity values ​​of multiple sensors 120 at the same time can be averaged and then the humidity change can be calculated. The humidity change can be the curvature on the curve constructed by the real-time humidity within the first time period, or it can be a change ratio (such as the initial humidity is 80, and it is 60 after the first time period, then the humidity change is 25%). In this regard, the embodiments of the present application do not limit it, and those skilled in the art can selectively set it according to actual conditions.

[0032] The object covering state in step S300 is used to indicate whether there is a wet object.

[0033] The first target power value in step S400 can be selectively set according to actual needs. In some embodiments, the first target power value is set to the maximum heating power supported by the drying device. The heating stop condition can be selectively set according to actual needs, such as the humidity value is less than a preset humidity threshold, or the temperature is higher than a preset temperature threshold, or the heating duration is higher than a preset threshold.

[0034] It is understandable that after executing step S400, when the automatic drying request is triggered again, the process will jump to step S100 and execute again.

[0035] It is understandable that preheating the hanging body 110 based on a preset power control algorithm includes: Obtaining a preset critical humidity value of the environment and an initial estimated humidity value determined based on multiple real-time humidity values ​​of the sensor array when an automatic drying request is triggered; When the initial estimated humidity value is less than the critical humidity value of the environment, within the first time period, the heating power of the hanging body 110 is repeatedly reduced from the preset maximum detection power until it reaches the preset minimum detection power; When the initial estimated humidity value is greater than or equal to the critical humidity value of the environment, the heating power of the hanging body 110 is maintained at the maximum detection power within a first period of time.

[0036] The maximum detection power is the actual maximum power that can be executed. If it can be set to the maximum heating power supported, the maximum detection power is the maximum heating power. The purpose of heating for the first time at the maximum detection power is to heat the items (such as clothes) as quickly as possible, so that the humidity of the items can be released as soon as possible, so as to judge whether it is a wet item or a dry item.

[0037] It is understandable that by increasing the judgment of the critical humidity value of the environment, it is possible to distinguish whether the humidity is caused by natural weather or wet objects, and then different powers can be selected for preheating to identify whether there are wet objects according to the humidity values ​​collected in real time during the preheating process, thereby improving the accuracy of wet object identification. For example, in subtropical areas, the air humidity is generally between 50-80, and below 80 is the value in most weather conditions. In order to reduce misjudgments caused by natural weather and repeated heating caused by natural humidity, the critical humidity value of the environment can be set to 80 degrees. When the humidity is less than 80, it is necessary to distinguish between natural weather and wet objects. The purpose of heating from the maximum detection power is to heat the object quickly, but it cannot be high power all the time. For example, the high power of 70 humidity causes the humidity around the natural environment to drop quickly. By lowering the heating power to the minimum detection power for continuous heating, the object can be kept in a slightly hot state as much as possible, reducing the probability of misjudgment of wet objects. When it is above 80, in order to exclude the influence of natural weather, preheating is performed at the maximum detection power, so that the humidity value can better reflect the humidity changes of the object.

[0038] The embodiments of the present application do not limit how to reduce the maximum detection power, and those skilled in the art can selectively set it according to actual needs, such as setting a preset step decrease or setting multiple intermediate transition detection powers between the maximum detection power and the minimum detection power based on experimental data.

[0039] The minimum detection power can be selectively set according to actual needs, and the minimum detection power that can identify the humidity difference between wet objects and the environment can be determined based on the humidity curves when different types of objects are heated and the humidity curves in the natural environment.

[0040] It is understandable that the humidity change is determined by using a plurality of real-time humidity values ​​collected by the sensor array within the first time period, including: According to multiple real-time humidity values ​​of the sensor array at the same collection time, obtain the real-time estimated humidity value corresponding to each collection time within the first time period; Determine the humidity change trend within the first time period according to the real-time estimated humidity value corresponding to each collection moment; When the humidity change trend shows a downward trend, the humidity change amount of the real-time estimated humidity value within the first time period is determined.

[0041] It is understandable that the real-time humidity values ​​in the sensor array at the same collection moment may be averaged or weighted to determine the real-time estimated humidity value at each collection moment.

[0042] The downward trend of humidity change indicates that the humidity value continues to decrease within the first period of time, or that the humidity value first decreases and then stabilizes within a preset stable threshold range within the first period of time. The stable threshold range represents the humidity of the object when it is in a dry state.

[0043] The humidity change is the ratio of the humidity difference between the humidity value at the end of the first duration and the humidity value at the beginning of the first duration to the humidity value at the beginning of the first duration. of heating, then ( Humidity value - Humidity value) / The humidity value indicates the humidity change.

[0044] It is understandable that, according to the humidity change, obtaining the object coverage state of the wet object sensing area 111 includes at least one of the following: When the humidity change is less than or equal to a preset threshold of the humidity change of the article, determining that the article covering state is a wet article; In the case where the humidity change is greater than a preset threshold value of the humidity change of the article, when heating is performed at a preset second target power value for a preset second time period and after the second time period, it is determined that a plurality of real-time humidity values ​​of the sensor array are maintained within a preset humidity range, it is determined that the article covering state is a non-humid article; Among them, the second time duration is shorter than the first time duration; the second target power value and humidity range are both determined based on the real-time humidity value and the environmental critical humidity value corresponding to the automatic drying request.

[0045] The threshold value of the change in humidity of the object can be determined by performing simulated heating on each object according to the first duration and the power control algorithm.

[0046] Determining whether multiple real-time humidity values ​​of the sensor array are maintained within a preset humidity range can be expressed as determining whether the real-time estimated humidity value of the sensor array is greater than a preset humidity threshold, or can be expressed as determining whether each real-time humidity value is within the humidity range.

[0047] When the ambient humidity is high, when heating is performed with a lower heating power, the presence of wet items will not cause the humidity to increase, but the humidity in the air will decrease, so the real-time humidity value will be maintained at a preset low value and will no longer rise, so that it is possible to determine whether there are wet items based on the real-time humidity value. Similarly, when the ambient humidity is low, when heating is performed with a higher heating power, the presence of wet items will cause the humidity to increase, so the real-time humidity value will be maintained at a higher value, so it is possible to determine whether there are wet items based on whether the real-time humidity value is higher than the preset value. Therefore, by adding the second target power for preheating when the humidity change is greater than the preset item humidity change threshold, the accuracy of wet item recognition can be further improved.

[0048] For example, Figure 5 As shown, when the humidity change is greater than the threshold value of the humidity change of the item (i.e., 20%), when the initial estimated humidity value corresponding to the automatic drying request is greater than 80, heating is continued for 2 minutes (i.e., the second duration) at the configured minimum heating power. If the maximum detection power has been used for heating, when there are wet items, the humidity will increase, otherwise the humidity will be maintained at a lower value. Similarly, when the initial estimated humidity value corresponding to the automatic drying request is less than 80, setting the second target power to the maximum detection power for heating for two minutes will accelerate the dissipation of the humidity of the wet items, thereby causing the humidity to increase. Therefore, by judging whether the real-time estimated humidity value is maintained at a higher value or whether each real-time humidity value is within a higher range, it is possible to quickly identify whether there are wet items.

[0049] It is understandable that each sensor 120 in the sensor array is a temperature and humidity sensor 120, and the automatic drying request is triggered by the following steps: When the hanging body 110 is not heated, the real-time temperature value of each sensor 120 is obtained and the humidity change amount from the last heating stop is determined; When the real-time temperature value and humidity change both meet the preset automatic drying trigger conditions, an automatic drying request is generated.

[0050] The temperature is read when the drying main body 110 is not heated, in order to determine whether the current ambient temperature requires heating (in order to save power), and also to determine whether the heating has just been completed and then briefly stopped (to reduce the probability of repeated startup). That is, the automatic drying trigger condition can try to eliminate the interfering temperature and return to the natural temperature. For example, if an abnormal temperature is detected, such as a temperature greater than 40 degrees, heating will not be performed, and it will remain stopped until the temperature drops. If the temperature does not drop, the drying main body 110 will not heat up. This can reduce the situation where frequent startups are caused by shutting down halfway through use, stopping briefly, and then restarting.

[0051] It is understandable that obtaining the real-time temperature value of each sensor 120 includes: Get the preconfigured drying mode; When the drying mode indicates that automatic drying is supported and the heating of the hanging body 110 is not started, the real-time temperature value is collected periodically through the sensor 120.

[0052] The drying modes include automatic drying and continuous drying. Automatic drying is supported in automatic drying mode.

[0053] It is understandable that the first duration and the power control algorithm are determined by the following steps: Obtaining humidity change curves of multiple different types of items at different heating powers; wherein each humidity change curve represents the relationship between humidity change and time when heating is performed at a corresponding heating power; Determine the first duration according to the duration covered by the curve segment with the most obvious humidity change in each humidity change curve; According to the humidity change curves of the same type of items within the first time period, a control moment and a control power corresponding to the control moment are selected; wherein the control power represents the humidity change curves of the same type of items that produce the maximum humidity change trend at the control moment; A power control algorithm is obtained according to the control time and the corresponding control power.

[0054] It is understandable that the maximum heating power and the minimum heating power in this application refer to the power supported by the configuration. The humidity change curve is a curve obtained by fitting the real-time humidity value obtained by heating and collecting the heating power within the maximum heating power and the minimum heating power range when the humidity is lower than the critical humidity value of the environment.

[0055] The first duration covers the curve segment where the humidity change is most obvious in the humidity change curves of various types of items.

[0056] For example, according to the possible types of heating products, stockings (about 1.5 minutes to distinguish), ordinary thin clothes (about 3 minutes), ordinary towels (about 2.5 minutes), and thick bath towels (about 4 minutes) are selected, and the humidity change curve is simulated respectively. It is found that the humidity change of ordinary thin clothes is most obvious within 3 minutes, the humidity change of ordinary towels is most obvious within 2.5 minutes, and the humidity change of thick bath towels is most obvious within 4 minutes. Then the most comprehensive situation is selected, and 3 minutes is determined as the first duration. Taking stockings as an example, multiple heating powers (heating power 1~n) are selected from the maximum heating power and the minimum heating power to construct the humidity change curve. Assuming that at time t, among the heating powers 1~n, the curvature of heating power 2 is greater than that of other heating powers, heating power 2 is used as a control power, and time t is the control time of heating power 2. By analogy, multiple control powers and control times are determined.

[0057] For example, refer to Figure 5 As shown, the first target power is set to the maximum heating power, the critical humidity value of the environment is set to 80, and the threshold value of the humidity change of the item is set to 20%; the automatic drying trigger condition is set to the humidity change amount from the last time the heating was stopped is greater than the threshold value of the humidity change of the item (that is, 20%) and the temperature is less than the preset temperature threshold (the temperature threshold represents the natural temperature under which the natural drying efficiency is lower than the drying efficiency of the hanging device). The maximum detection power is the maximum heating power, and the minimum detection power is the minimum heating power. The control method is as follows: S1: Get the real-time temperature value and the real-time humidity value, and perform the automatic drying steps according to the real-time temperature value and the real-time humidity value, as follows: When the real-time temperature value and the real-time humidity value meet the automatic drying triggering condition, the automatic drying request is triggered; An initial estimated temperature value is determined according to the real-time temperature value corresponding to the automatic drying request.

[0058] S2. When the initial estimated temperature value is greater than or equal to 80, identify wet items in a natural environment with high humidity and dry the wet items. The specific steps are as follows: S2.1 Turn on the maximum heating power and heat for 3 minutes, then determine the humidity change within 3 minutes; S2.2: When the humidity change is less than or equal to 20%, it is determined that there is a wet item and heating is continued at the maximum heating power. When the real-time estimated humidity value detected in the cycle is less than 15, it indicates that the item is dry, heating is stopped, and the process jumps to S4; S2.3 determines the real-time estimated humidity value 2 minutes later after heating for 2 minutes at the minimum heating power when the humidity change is greater than 20%; when the real-time estimated humidity value is slightly different from the real-time estimated humidity value 2 minutes ago, that is, it remains at a low value, it is determined that there are no items or undried items, and heating is stopped and the process goes to S4.

[0059] S3. When the initial estimated temperature value is less than 80, identify wet items under normal humidity in the natural environment and dry the wet items. The specific steps are as follows: S3.1 Turn on the heating for 3 minutes, and adjust the heating power from high to low (such as from the maximum heating power to the minimum heating power) within 3 minutes; and determine the humidity change within 3 minutes.

[0060] S3.2: When the humidity change is less than or equal to 20%, it is determined that there is no object or the object is dry, and the heating is stopped and the process goes to S4; S3.3 When the humidity change is greater than 20%, heat at the maximum heating power for 2 minutes to obtain the real-time estimated humidity value after 2 minutes. If the real-time estimated humidity value does not decrease or the decrease is less than the preset amplitude threshold, that is, it remains at a high value, it is determined that there are wet items and heating is continued at the maximum heating power. After detecting that the real-time estimated humidity value is less than 15, it indicates that the item is dry, and heating is stopped and jump to S4.
