[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0051] Please refer to Figure 1 , Figure 1Schematic structural diagram of the dryer provided by an embodiment of the present application. The dryer 1 can be an exhaust dryer, a heat pump dryer, a condensation dryer, etc. Exemplarily, the dryer 1 can include a housing 10, an inner drum 20, and a humidity sensor 30. Of course, the dryer 1 can also include other structural components, such as a rotating shaft, bearings, a display panel, etc. (not shown in the figure), which are not specifically limited herein.

[0052] Among them, the inner drum 20 can be arranged inside the housing 10. That is to say, the housing 10 is equivalent to the encapsulation structure of the dryer 1, and a display panel, operation buttons, etc. can be arranged on the housing 10. The inner drum 20 can be used to carry clothes, and the inner drum 20 can rotate relative to the housing 10. Cooperating with the program of the dryer 1 can achieve drying of the clothes.

[0053] The humidity sensor 30 can be arranged close to the inner drum 20. For example, the housing 10 is also provided with an opening, and the dryer 1 can further include a door body 40. The door body 40 is rotatably connected to the housing 10 to close or open the opening of the housing 10. In the direction of gravity, the humidity sensor 30 can be arranged below the side of the housing 10 close to the inner drum 20. When the inner drum 20 rotates, it can randomly contact the clothes in the inner drum 20 to detect the humidity value of the clothes in the inner drum 20. For example, the humidity sensor 30 can be a bimetallic strip sensing device. When the clothes rotate with the inner drum 20 in the inner drum 20, they can randomly contact the metal strip to achieve humidity collection of the clothes in the inner drum 20. The humidity sensor 30 can also be a water-resistant humidity-sensitive resistor sensing device, a ceramic pressure sensing device, a humidity-sensitive capacitor sensing device, an epoxy thermistor sensing device, etc. The humidity sensor 30 can characterize the humidity value of the clothes carried in the inner drum through an electrical signal.

[0054] Please combine Figure 1 and refer to Figure 2 , Figure 2 Block diagram of the dryer provided by an embodiment of the present application. The dryer 1 of the embodiment of the present application can further include at least one memory 50 and at least one processor 60, and the memory 50 and the processor 60 are electrically connected. A computer program is stored on the memory 50, and the processor 60 executes control of the dryer by calling the computer program stored on the memory 50. Those skilled in the art can understand that the dryer structure shown in the figure does not constitute a limitation on the dryer, and it can include more or fewer components than shown, or combine some components, or have different component arrangements.

[0055] The processor 60 is the control center of the dryer 1. It uses various interfaces and circuits to connect all parts of the dryer 1. By running or loading software programs and / or modules stored in the memory 50, and by calling the data stored in the memory 50, it executes various functions of the dryer 1 and processes data, thereby monitoring the dryer 1 as a whole.

[0056] It should be noted that currently, the dryness determination algorithm for special material loads in dryers mainly determines dryness through the temperature difference value between the air inlet and outlet of the dryer. This method is easily affected by the machine state. If the machine continuously dries, errors will occur when determining dryness based on the temperature difference value, easily leading to the situation of under-drying or over-drying.

[0057] To solve the above problems, the program algorithm running in the processor 60 in this application embodiment is improved. The processor 60 in the dryer 1 will load the instructions corresponding to the processes of one or more application programs into the memory 50 according to the following steps, and the processor 60 will run the application programs stored in the memory 50 to implement various functions.

[0058] Please combine Figure 1 and Figure 2 and refer to Figure 3 , Figure 3 which is the first flowchart of the control method for the dryer provided by the embodiment of this application. The embodiment of this application provides a control method for a dryer, including:

[0059] 101. Obtain the material of the target clothing carried in the inner drum.

[0060] When the user needs to use the dryer 1 to dry clothes, the material of the target clothing or the clothes to be dried carried in the inner drum 20 can be identified first. Among them, the materials of the clothes can include hemp, leather, polyester, wool, silk, cotton cloth, woolen cloth, silk, acrylic, pure silk, and down, etc. There are various ways to identify the materials of the clothes to be dried. For example, a scanner can be set in the inner drum 20 of the dryer 1 or at the entrance of the inner drum 20, and the material of the clothes can be identified by scanning the tag or label of the clothes to be dried. For example, a camera can be set in the inner drum 20, and the corresponding material can be matched from the database through the captured pictures; for another example, the tag or label of the clothes to be dried can be scanned through the camera of the user's electronic device, or the material of the clothes to be dried can be identified by taking pictures of the clothes to be dried through the camera of the electronic device. The specific identification method is not specifically limited here.

[0061] Among them, when the clothes to be dried are placed in the inner drum 20 of the dryer 1, the target clothing carried by the dryer can be obtained. After identifying the material of the clothes to be dried, the material of the target clothing carried in the inner drum 20 can be obtained.

[0062] 102. After the drying program of the dryer is started, obtain multiple humidity values of the target clothes in the inner drum within the first preset duration.

[0063] The working mode of the dryer 1 can be continuous drying, and the working mode of the dryer 1 can also be single drying. Single drying means that the dryer 1 only performs one drying program within a period of time. After the drying is completed, the temperature inside the dryer 1 drops to the ambient temperature. When the next single drying is carried out, the temperature inside the dryer 1 can be heated from the ambient temperature to the preset drying temperature and then the clothes are dried. Continuous drying means the process of carrying out the next drying after one drying is completed. In the continuous drying working mode, since the dryer 1 sets a fixed cooling time for the drying program, therefore, after the previous drying is completed, the temperature inside the inner drum 20 does not drop to the ambient temperature, but enters the next drying after a short interval. Affected by the operating state of the machine, if the drying is judged by the temperature difference between the air inlet and outlet of the inner drum 20, it is easy to generate a judgment error, resulting in the situation that the clothes are not dried or over-dried. Therefore, in this embodiment, based on the material of the target clothes carried in the inner drum 20 and combined with multiple humidity values of the target clothes in the inner drum 20, the drying of the target clothes in the inner drum 20 is judged to reduce the influence of the machine operating state on the drying effect.

[0064] The humidity sensor 30 can measure the humidity value of the clothes in the inner drum 20. After the drying program is started, a certain frequency can be set for the humidity sensor 30 to collect the humidity value. Exemplarily, the method for obtaining the humidity value can be: after the drying program of the dryer 1 is started, control the inner drum 20 of the dryer 1 to work at the initial working speed for the first preset duration; obtain multiple sub-humidity values in each of multiple time periods within the first preset duration; obtain the humidity value of each time period according to the multiple sub-humidity values in each time period, and thus multiple humidity values within the first preset duration can be obtained. Among them, for the humidity value of each time period, the humidity value can be calculated by the average value of the multiple sub-humidity values in this time period. For example, the humidity sensor 30 can be collected at a preset frequency, and the preset frequency can be 1 time per 500 ms. The first preset duration can be 30 minutes. In each time period within the first preset duration, such as within 1 minute, multiple sub-humidity values can be collected, and the average value of the multiple sub-humidity values within each 1 minute is used as the humidity value of this 1 minute, and thus 30 humidity values within the first preset duration can be obtained. Among them, in order to ensure the accuracy of humidity detection, a certain delay time can be set at the start of the drying program. For example, it can be selected to delay for 5 minutes and then perform the detection of the above sub-humidity values.

[0065] Among them, the start of the drying program can be that the user controls the dryer 1 to start the drying program by touching a physical button or a virtual button, and through a voice command. The drying program of the dryer 1 can include multiple drying programs for target clothes of different materials. For example, there is a down drying program corresponding to down materials, a wool drying program corresponding to wool materials, and a polyester drying program corresponding to polyester materials. Of course, the clothes to be dried can also be divided into soft materials, crisp materials, shiny materials, heavy materials, and transparent materials. At this time, the dryer 1 is also provided with corresponding drying programs. There can also be other types of classification methods for the drying programs, such as multiple drying programs classified according to the clothing weight value. For example, a four-piece set drying program is set for a large weight load, and a small load drying program is set for a small weight load. The user can select according to needs, which is not limited here.

[0066] 103. Calculate the remaining drying duration of the drying program according to the material of the target clothes and multiple humidity values.

[0067] There are different drying programs corresponding to different materials of the target clothes. Correspondingly, different drying durations can be set for different drying programs. For example, the drying set duration corresponding to the material of the target clothes can be obtained first, and the drying set duration can be adjusted according to the relationship between multiple humidity values and the humidity threshold to obtain the remaining drying duration. For example, when drying down materials, the drying set duration can be 20 minutes. If it is detected that multiple humidity values within the first preset duration are all less than the humidity threshold, the drying set duration can be adjusted, such as subtracting 5 minutes, to obtain the remaining drying duration. For example, the remaining drying duration can be 15 minutes.

[0068] For the acquisition of the humidity threshold, it can be through the following method: obtain multiple test humidities when the inner drum 20 does not carry clothes, and obtain the humidity threshold according to the multiple test humidities. For example, multiple test humidities when the inner drum 20 does not carry clothes at different drying stages can be detected, and the humidity threshold can be obtained by, for example, calculating the average value of the multiple test humidities.

[0069] Exemplarily, when the material of the target clothing is the first material such as down material, the first remaining drying duration of the drying program is calculated according to the first material and multiple humidity values within the first preset duration. When the material of the target clothing is the second material such as wool material, the second remaining drying duration of the drying program is calculated according to the second material and multiple humidity values within the first preset duration. Since the water absorption of the wool material is greater than that of the down material, that is, the down material is easier to dry, therefore, the second remaining drying duration is greater than the first remaining drying duration. When the material of the target clothing is the third material such as polyester material, the third remaining drying duration is calculated according to the third material and multiple humidity values. Since the water absorption of the polyester material is greater than that of the wool material, that is, the wool material is easier to dry, therefore, the third remaining drying duration is greater than the second remaining drying duration.

[0070] 104. When the remaining drying duration of the drying program ends, the drying program is turned off.

[0071] After calculating the remaining drying duration, when the drying program runs until the remaining drying duration ends, the drying program is automatically controlled to turn off, that is, the inner drum 20 enters the cooling stage. The dryer 1 can be intelligently controlled to achieve the effect of stopping when the clothes are dry.

[0072] It should be noted that since the drying process of the drying program of the dryer 1 on the target clothing will cause the inner drum to be in a high-temperature state, and the fundamental reason for generating high temperature is the operation of the engine or other functional components of the dryer 1. If the dryer 1 is directly turned off after the target clothing reaches the target moisture content, that is, after the drying program is turned off, it will cause damage to the engine or other functional components. Therefore, after the drying program of the dryer 1 ends, that is, after the remaining running time ends, the dryer 1 can be kept in neutral for a certain period of time to make the engine or other functional components in the dryer 1 stop running completely, and then the dryer is turned off to improve the service life of the dryer 1. Among them, the time maintained in neutral can be 5 minutes, and this process can be regarded as the cooling and temperature reduction stage.

[0073] In addition, after the user dries the target clothing to the target moisture content through the dryer 1, that is, after the drying program is turned off, wrinkles are generated due to the winding state of the target clothing in the inner drum 20 during the drying process. To eliminate the wrinkles, the dryer 1 can also have an anti-wrinkle function. Specifically, after the dryer 1 is kept in neutral for a certain period of time, the anti-wrinkle function of the dryer 1 is turned on, and after the anti-wrinkle operation ends, the dryer 1 is controlled to stop running.

[0074] As can be seen from the above, in the control method of the dryer according to the embodiments of the present application, for different materials of the target clothes carried in the inner drum 20, by detecting multiple humidity values of the target clothes in the inner drum 20, the remaining drying time of the drying program of the dryer 1 is calculated, without considering the influence of temperature changes during continuous drying on the drying program, which can reduce the error in judging the drying of different clothes materials during continuous drying and improve the drying effect.

[0075] Please combine Figures 1 to 3 and refer to Figure 4 , Figure 4 which is the second schematic flowchart of the control method of the dryer provided by the embodiments of the present application. The specific operation steps of the control method of the dryer can be as follows:

[0076] 201. Obtain the weight value of the target clothes carried in the inner drum.

[0077] The dryer 1 has different drying programs according to the materials of the clothes to be dried, and different drying programs can also be set according to the weight of the clothes to be dried. Moreover, the priority of the drying program set according to the weight value of the target clothes can be set higher than the priority of the drying program set according to the material of the target clothes. It can be understood that the weight of the clothes to be dried has a certain influence on the remaining drying time. The weight of the clothes to be dried can be classified. For example, it can be divided into large weight loads, small weight loads, and other loads one and other loads two. The weights of other loads one and other loads two are similar, and the drying program they run is determined according to the humidity value. The weight of the clothes to be dried with a large weight load is greater than the weight of the clothes to be dried with other loads. The weights of the clothes to be dried with other loads one and two are greater than the weight of the clothes to be dried with a small weight load. First, a weight measurement of the clothes to be dried can be performed. If it is a large weight load, the corresponding drying program for the large weight is run. If it is a small weight load, the corresponding drying program for the small weight is run. If it is other load one, when the humidity value meets the requirements, the corresponding drying program for other load one can be run. If it is other load two, the drying program for judging the drying according to the material of the clothes to be dried can be entered.

[0078] A pressure sensor can be set in the dryer 1 to detect the weight value of the target clothes in the inner drum 20. Of course, the weight value of the target clothes in the inner drum 20 can also be detected by other means, which is not limited here.

[0079] 202. After the drying program of the dryer is started, obtain multiple humidity values of the target clothes in the inner drum within the second preset time.

[0080] The second preset duration may be the same as the first preset duration. The acquisition of multiple humidity values of the target clothing in the inner drum 20 can refer to the description in step 102, with the only difference being that the time period for acquiring the humidity values is different from that in step 102. For example, it can be in sequence. First, acquire multiple humidity values within the second preset duration, and then acquire multiple humidity values within the first preset duration.

[0081] 203. Calculate the remaining drying duration of the drying program based on the weight value and multiple humidity values of the target clothing.

[0082] There are different drying programs corresponding to different weight values of the target clothing. Correspondingly, different drying durations can be set for different drying programs. For example, first obtain the set drying duration corresponding to the weight value of the target clothing, and adjust the set drying duration according to the relationship between the multiple humidity values and the humidity threshold to obtain the remaining drying duration. For example, when drying a large-weight load, the set drying duration can be 40 minutes. If all the multiple humidity values are less than the humidity threshold, it means that the moisture content of the large-weight target clothing is low. At this time, the drying duration can be reduced. For example, the remaining drying duration obtained by adjusting the set drying duration can be 35 minutes. The acquisition of this humidity threshold can be the same as the acquisition method of the humidity threshold in step 103.

[0083] Exemplarily, when the weight value of the target clothing is other load one, if the humidity values within the second preset duration are all greater than the temperature threshold, the remaining drying duration of the drying program corresponding to other load one can be run. If the weight value of the target clothing is not other load one, determine whether to start the drying program for large weight. If the drying program for large weight such as the four-piece set drying program is started, run the remaining drying duration of the corresponding drying program. If the drying program for large weight is not started, determine the relationship between the humidity values within the first preset duration and the humidity threshold. If all the multiple humidity values within the first preset duration are less than the humidity threshold and all the multiple humidity values within the second preset duration are within the humidity threshold, run the remaining drying duration corresponding to the drying program for small weight. If not all the multiple humidity values within the first preset duration are less than the humidity threshold, determine which drying program corresponding to the material to enter according to the relationship between the multiple humidity values within the second preset duration and the humidity threshold.

[0084] 204. Obtain the material of the target clothing carried in the inner drum.

[0085] When the user needs to use the dryer 1 to dry clothes, the material of the target clothes or the clothes to be dried carried in the inner drum 20 can be identified first. The materials of the clothes can include hemp, leather, polyester, wool, silk, cotton, woolen cloth, silk, acrylic, real silk, and down, etc. There are various ways to identify the material of the clothes to be dried. For example, a barcode scanner can be set in the inner drum 20 of the dryer 1 or at the entrance of the inner drum 20, and the material of the clothes can be identified by scanning the tag or label of the clothes to be dried. For example, a camera can be set in the inner drum 20, and the corresponding material can be matched from the database through the captured pictures. For another example, the tag or label of the clothes to be dried can be scanned through the camera of the user's electronic device, or the material of the clothes to be dried can be identified by taking pictures of the clothes to be dried through the camera of the electronic device. The specific identification method is not specifically limited here.

[0086] Among them, by placing the clothes to be dried in the inner drum 20 of the dryer 1, the target clothes carried by the dryer can be obtained. After identifying the material of the clothes to be dried, the material of the target clothes carried in the inner drum 20 can be obtained.

[0087] 205. Calculate the remaining drying duration of the drying program according to the material of the target clothes and multiple humidity values.

[0088] For different materials of the target clothes, there are different drying programs. Correspondingly, different drying durations can be set for different drying programs. For example, the drying set duration corresponding to the material of the target clothes can be obtained first, and the drying set duration can be adjusted according to the relationship between multiple humidity values and the humidity threshold to obtain the remaining drying duration. For example, when drying down material, the drying set duration can be 20 minutes. If it is detected that multiple humidity values within the first preset duration are all less than the humidity threshold, the drying set duration can be adjusted, such as subtracting 5 minutes, to obtain the remaining drying duration. For example, the remaining drying duration can be 15 minutes.

[0089] For obtaining the humidity threshold, it can be done in the following way: Obtain multiple test humidities when there are no clothes carried in the inner drum 20, and obtain the humidity threshold according to the multiple test humidities. For example, multiple test humidities when there are no clothes carried in the inner drum 20 at different drying stages can be detected, and the humidity threshold can be obtained by, for example, taking the average value of the multiple test humidities.

[0090] Exemplarily, when the material of the target clothing is the first material such as down material, the first remaining drying duration of the drying program is calculated based on the first material and multiple humidity values within the first preset duration. When the material of the target clothing is the second material such as wool material, the second remaining drying duration of the drying program is calculated based on the second material and multiple humidity values within the first preset duration. Since the water absorption of the wool material is greater than that of the down material, that is, the down material is easier to dry, therefore, the second remaining drying duration is greater than the first remaining drying duration. When the material of the target clothing is the third material such as polyester material, the third remaining drying duration is calculated based on the third material and multiple humidity values. Since the water absorption of the polyester material is greater than that of the wool material, that is, the wool material is easier to dry, therefore, the third remaining drying duration is greater than the second remaining drying duration.

[0091] 206. When the remaining drying duration of the drying program ends, the drying program is turned off.

[0092] After calculating the remaining drying duration, when the drying program runs until the remaining drying duration ends, the drying program is automatically controlled to turn off, that is, the inner drum 20 enters the cooling stage. The dryer 1 can be intelligently controlled to achieve the effect of stopping when the clothes are dry.

[0093] It should be noted that since the drying program of the dryer 1 will cause the inner drum to be in a high-temperature state during the drying process of the target clothing, and the fundamental reason for generating high temperature is the operation of the engine or other functional devices of the dryer 1. If the dryer 1 is directly turned off after the target clothing reaches the target moisture content, that is, after the drying program is turned off, it will cause damage to the engine or other functional devices. Therefore, after the drying program of the dryer 1 ends, that is, after the remaining running time ends, the dryer 1 can be kept in neutral for a certain period of time to completely stop the operation of the engine or other functional devices in the dryer 1, and then the dryer is turned off to improve the service life of the dryer 1. The time maintained in neutral can be 5 minutes, and this process can be regarded as the cooling and temperature reduction stage.
