[0002] At present, clothes handling equipment such as dryers and washer-dryers have become indispensable household appliances in family life. Clothes can be dried very conveniently using these clothes handling equipment.

[0003] Clothes processing equipment in related technologies usually has multiple drying modes, such as cotton and linen drying, chemical fiber drying, mixed drying, etc. Utilizing these drying modes, clothes of different material types can achieve the best drying effect through different drying programs without damaging the clothes.

[0004] However, in actual use, users need to manually set the corresponding drying mode according to the material type of the clothes. Because users are not familiar with or often forget to change the drying mode, the drying mode used does not match the material type of the clothes, resulting in poor drying effect. In particular, it may lead to the use of a higher temperature drying mode such as cotton and linen drying to dry clothes made of chemical fiber or silk, resulting in damage to the clothes made of chemical fiber or silk.

[0068] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0069] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0070] A drying control method, device, clothing processing equipment and storage medium proposed according to an embodiment of the present application are described below in conjunction with the accompanying drawings.

[0071] The embodiment of the present application provides a drying control method, which installs a temperature sensor in a clothing processing device, detects the surface temperature of the clothing in real time through the temperature sensor, and distinguishes the material type of the clothing through the change parameters of the clothing surface temperature. The temperature in the barrel is intelligently controlled by the identified material type, so that the drying program is suitable for the material type of the clothing to achieve the best drying effect. It can also avoid using the drying mode of cotton and linen clothing to dry chemical fiber or silk clothing, and avoid damaging chemical fiber or silk clothing due to excessive temperature.

[0072] See also Figure 1 , the method specifically comprises the following steps:

[0073] Step 101: Monitor the surface temperature of the clothes to be dried in real time.

[0074] The execution subject of the embodiment of the present application is a clothing processing device or a controller arranged in the clothing processing device. The clothing processing device may be a device with the function of drying fabrics, such as a dryer, a washer-dryer, etc. A temperature sensor is arranged in the clothing processing device, and the temperature sensor may be a non-contact sensor for detecting temperature, such as a thermopile temperature sensor, an infrared temperature sensor, a microwave temperature measurement temperature sensor, etc. The detection range of the temperature sensor covers the inner area of ​​the drum of the clothing processing device, and the detection probe of the temperature sensor may be a single-point probe or an array probe. The temperature sensor may be installed on the inner side of the door of the drum, that is, installed on the side of the door of the drum facing the inside of the drum, such as Figure 2 As shown, a receiving groove 2 is provided inside the drum door, and a temperature sensor 3 is provided in the receiving groove 2. The embodiment of the present application does not limit the installation position of the temperature sensor, as long as the detection range of the temperature sensor can cover the area inside the drum.

[0075] When the user needs to use the clothes processing device to dry the clothes to be dried, the clothes to be dried are placed in the barrel and the drying program is started. The clothes processing device detects that the drying program is started, controls the temperature sensor to detect the surface temperature of the clothes to be dried placed in the barrel in real time, and the temperature sensor transmits the detected surface temperature to the controller. The controller records the surface temperature and the detection time corresponding to the surface temperature.

[0076] Since the clothes rotate continuously with the drum during the temperature detection process of the temperature sensor, the position detected by the temperature sensor is different each time, which inevitably leads to large differences between the temperature values ​​detected each time, especially when the detection position falls on the drum wall, the detected temperature value will be higher. Therefore, in the embodiment of the present application, the temperature can be detected once every first preset unit time, and every first preset time, the temperature characteristic value is determined from the temperature detected in each first preset unit time within the first preset time, and the temperature characteristic value is used as the surface temperature of the current clothes to be dried. The temperature characteristic value can be at least one of the minimum temperature, the median temperature, the average temperature, and the maximum temperature. Among them, the first preset unit time can be 1ms or 2ms, etc., and the first preset time can be 10ms or 20ms, etc.

[0077] For example, in some embodiments, the temperature sensor detects the temperature every 1 ms, and selects the lowest temperature value from the 10 temperature values ​​detected within these 10 ms every 10 ms as the surface temperature of the current clothes to be dried.

[0078] Alternatively, the temperature is detected once every first preset unit time, and every first preset time, the temperature characteristic value of the first preset time is determined from the temperature detected in each first preset unit time within the first preset time. A second preset time is set, the second preset time is greater than the first preset time, and the second preset time is an integer multiple of the first preset time, and the temperature characteristic value of the second preset time is determined based on the temperature characteristic values ​​of multiple first preset time within the second preset time. The temperature characteristic value of the second preset time is used as the surface temperature of the current clothes to be dried. The temperature characteristic value can be at least one of the minimum temperature value, the median temperature value, the average temperature value, and the maximum temperature value.

[0079] For example, the lowest temperature value can be selected from the temperatures detected in each first preset unit time period within the first preset time period as the temperature characteristic value of the first preset time period. According to the multiple lowest temperature values ​​selected within the second preset time period, the average value of the selected multiple lowest temperature values ​​is calculated, and the average value is used as the surface temperature of the current clothes to be dried. Alternatively, the median, maximum value or minimum value is selected from the multiple selected lowest temperature values ​​as the surface temperature of the current clothes to be dried.

[0080] The first preset unit time length may be 1 ms or 2 ms, etc., the first preset time length may be 10 ms or 20 ms, etc. The second preset time length may be 80 ms or 100 ms, etc.

[0081] For example, the temperature sensor detects the temperature every 1ms, selects the lowest temperature value from the 10 temperature values ​​detected within 10ms every 10ms, selects the 10 lowest temperature values ​​within 100ms, calculates the average value of the 10 lowest temperature values, and uses the average value as the current surface temperature of the clothing. Alternatively, select the maximum value from the 10 lowest temperature values, and use the maximum value as the current surface temperature of the clothing. Alternatively, select the minimum value from the 10 lowest temperature values, and use the minimum value as the current surface temperature of the clothing. Alternatively, select the median from the 10 lowest temperature values, and use the median as the current surface temperature of the clothing.

[0082] By determining the current surface temperature of the clothes to be dried by any of the above methods, the influence of the rotation of the clothes on the temperature detection can be effectively eliminated, so that the determined surface temperature is closer to the actual surface temperature of the clothes to be dried, thereby greatly improving the accuracy of the surface temperature, improving the accuracy of the subsequent calculation of the changing parameters based on the surface temperature, and improving the accuracy of judging the material type of the clothes based on the changing parameters, thereby reducing the occurrence of poor drying effect or damage to the clothes due to inaccurate surface temperature.

[0083] Since the drum rotates continuously during the drying process, the clothes to be dried are shaken apart. The embodiment of the present application continuously collects temperature data of the surface temperature of the clothes to be dried through the thermopile sensor, so that the surface temperature of each part of the clothes to be dried can be collected. The material type of the clothes to be dried is subsequently determined based on the acquired surface temperature, which is conducive to determining the material type of each part of the clothes to be dried, and the judgment of the material type is more accurate and reliable.

[0084] Step 102: Determine the material type of the clothes to be dried based on the monitored surface temperature change parameters.

[0085] Since clothes made of non-cotton and linen materials such as chemical fiber or silk have a low moisture content and these materials easily evaporate water, the surface temperature of clothes made of non-cotton and linen materials rises faster during the drying process. Cotton and linen clothes have a high water absorption rate and are not easy to dry, so the surface temperature of the clothes rises slowly. Based on the characteristics of cotton and linen clothes and non-cotton and linen clothes, the embodiments of the present application have determined the highest surface temperature that non-cotton and linen clothes can tolerate during the drying process through a large number of tests, that is, if the surface temperature is greater than the highest tolerable surface temperature, the clothes will be damaged due to the high temperature. In the clothing processing equipment, the highest surface temperature that non-cotton and linen clothes can tolerate is set to a preset temperature, and the preset temperature can be 40°C or 45°C, etc.

[0086] In the embodiments of the present application, the value of the preset temperature is not limited. In actual applications, the specific value of the preset temperature is determined based on a large number of experiments.

[0087] The temperature sensor transmits each detected temperature to the controller. The controller records the time of receiving the temperature, and then determines the surface temperature at the current time by any method provided in step 101, and compares the determined surface temperature with the preset temperature. If the controller compares that the surface temperature of the current clothes to be dried is less than the preset temperature, it means that clothes of all material types will not be damaged by temperature at the current surface temperature, and then the clothes are continuously heated to increase the surface temperature, and the surface temperature of the clothes to be dried is continuously detected by the temperature sensor.

[0088] If the current surface temperature is greater than or equal to the preset temperature, it means that the surface temperature of the clothes to be dried has reached the highest temperature that non-cotton and linen clothes such as chemical fiber or silk can withstand. If the surface temperature continues to rise, these non-cotton and linen clothes are likely to be damaged due to excessive temperature. Therefore, the temperature is stopped at this time, and the surface temperature of the clothes is maintained at a fluctuation around the preset temperature by controlling the heating device. At this time, the change parameters of the surface of the clothes to be dried are calculated, and the material type of the clothes to be dried is determined based on the change parameters. The drying process is then controlled based on the material type to avoid damage to the clothes due to excessive temperature.

[0089] After determining the current surface temperature of the clothes to be dried by any of the above methods in step 101, it is determined whether the surface temperature is greater than or equal to the preset temperature. If so, the surface temperature of the clothes is maintained to fluctuate around the preset temperature, and the change parameters of the surface of the clothes to be dried are calculated. If not, the temperature detection is continued.

[0090] When the controller determines that the current surface temperature of the clothes to be dried is greater than or equal to the preset temperature, the change parameter of the surface of the clothes to be dried is calculated. The change parameter may include the temperature rise rate of the clothes surface. Specifically, the initial surface temperature of the clothes to be dried is obtained when the current drying program is started. The controller records the initial surface temperature and the start time of the current drying program. The controller also records the surface temperature determined each time after the drying program is started and the determination time corresponding to the surface temperature. Among them, the initial surface temperature and each surface temperature obtained after the drying program is started can be determined by any of the above-mentioned methods for determining the surface temperature, which will not be repeated here.

[0091] When it is determined that the current surface temperature reaches the preset temperature, the controller obtains the time when the surface temperature reaches the preset temperature, obtains the recorded initial surface temperature and the start time of the current drying program. The temperature difference between the preset temperature and the initial surface temperature of the clothes to be dried is calculated. Also, the time difference between the time when the surface temperature reaches the preset temperature and the start time of the current drying program is calculated, and the time difference is the time it takes for the surface temperature of the clothes to be dried to rise to the preset temperature. The ratio between the temperature difference and the time difference is calculated, and the ratio is determined as the temperature rise rate corresponding to the clothes to be dried.

[0092] In order to improve the accuracy of the heating rate, the heating rate may be calculated once every second preset unit time, and the second preset unit time may be 1 minute or 2 minutes, etc. Specifically, according to the above-mentioned method of determining the surface temperature, multiple surface temperatures are determined within each second preset unit time, and the sum of the multiple surface temperatures is calculated. The ratio of the sum to the second preset unit time is calculated, and the ratio is the heating rate within the second preset unit time.

[0093] For example, the second preset unit time is 1 minute, and 100 surface temperatures are determined within 1 minute. Then, the sum of the 100 surface temperatures is calculated, and the calculated sum is divided by 1 minute to obtain the heating rate within 1 minute.

[0094] In another implementation, a temperature curve of the surface temperature of the clothes to be dried fluctuating over time can also be drawn according to the surface temperature determined according to any of the above methods. According to the above method, the heating rate is calculated every second preset unit time, and the calculated heating rates are composed into a one-dimensional array. Then, according to the slope of each point on the drawn temperature curve, the second preset unit time in which the slope is less than the preset value determines the stage in which the surface temperature fluctuates most steadily. According to the time period corresponding to the stage in which the fluctuation is most stable, at least one heating rate calculated in the time period is obtained from the one-dimensional array composed of the above heating rates. The average value of the obtained heating rates is calculated, and the average value is used as the heating rate of the clothes to be dried. Alternatively, the median, maximum value or minimum value is selected from the obtained heating rates as the heating rate of the clothes to be dried.

[0095] After calculating the temperature rise rate of the surface of the clothes to be dried by any of the above methods, the material type of the clothes to be dried is determined according to the temperature rise rate. Specifically, the material type of the clothes to be dried can be determined by any of the following first or second methods.

[0096] First, a maximum or average value of the temperature rise rate of the surface of cotton and linen clothing during the drying process is determined through a large number of tests, and the maximum or average value is set as a preset threshold value for determining the material type of clothing. Alternatively, a minimum value of the temperature rise rate of the surface of non-cotton and linen clothing such as chemical fiber or silk during the drying process is determined through a large number of tests, and the minimum value is set as a preset threshold value for determining the material type of clothing.

[0097] After the temperature rise rate of the clothes to be dried is calculated in the above manner, the temperature rise rate is compared with a preset threshold value, and if the temperature rise rate is less than the preset threshold value, the material type of the clothes to be dried is determined to be cotton and linen. If the temperature rise rate is greater than or equal to the preset threshold value, the material type of the clothes to be dried is determined to be non-cotton and linen.

[0098] In the embodiment of the present application, the above-mentioned preset threshold value set in the clothing processing device may also be related to the type of clothing processing device. For example, if the clothing processing device is a heat pump dryer, when the heat pump dryer dries cotton and linen clothes, the temperature rises less than 0.4°C per minute. Figure 3 The figure shows the surface temperature fluctuation of cotton and linen clothes in the heat pump dryer. Therefore, the preset threshold value can be set as 0.4℃ / min in the heat pump dryer, that is, the temperature rise of 0.4℃ per minute is used as the dividing line. If the temperature rise rate is higher than this, it is identified as non-cotton and linen clothes, and if the temperature rise rate is lower than this, it is identified as cotton and linen clothes.

[0099] Second, through a large number of tests, the rate ranges of the temperature rise rate of the surface of cotton and linen clothes and non-cotton and linen clothes during the drying process are determined. Alternatively, the material types of clothes are further subdivided, and through a large number of tests, the rate ranges of the temperature rise rate of the surface of clothes of cotton and linen, chemical fiber, silk and other material types during the drying process are determined. And the mapping relationship between each material type and its corresponding rate range is pre-set in the controller of the clothing processing device.

[0100] After calculating the heating rate of the clothes to be dried in the above manner, the rate interval to which the heating rate belongs is determined. Then, from the mapping relationship between the material type and the rate interval set in advance, the material type corresponding to the rate interval to which the heating rate of the clothes to be dried belongs is obtained, and the obtained material type is determined as the material type of the clothes to be dried.

[0101] Since clothes made of non-cotton and linen materials such as chemical fiber or silk have a low moisture content, and the moisture contained in clothes of these materials is easily evaporated, the surface temperature of non-cotton and linen clothes such as chemical fiber or silk rises very quickly during the drying process. However, cotton and linen clothes have a high water absorption rate and are not easy to dry, and the surface temperature of cotton and linen clothes rises slowly during the drying process. Therefore, the embodiment of the present application automatically identifies the material type of the clothes based on the temperature rise rate of the surface of the clothes during the drying process, so that the clothes processing device can automatically identify the material type of the clothes to be dried, and the accuracy of determining the material type is very high, which helps to improve the accuracy of the subsequent control of the drying program based on the material type.

[0102] Step 103: According to the material type, control the drying program to dry the clothes to be dried.

[0103] The material type of the clothes to be dried is determined by any of the methods in the above step 102. If the determined material type is cotton and linen, the heating device is controlled to continue heating to increase the temperature in the barrel, thereby increasing the surface temperature of the clothes to be dried, so that the surface temperature is greater than the maximum temperature that non-cotton and linen clothes can withstand, that is, greater than the preset temperature, so that the cotton and linen clothes to be dried are dried at a higher temperature so that the clothes to be dried can be dried as quickly as possible.

[0104] In the process of drying cotton and linen clothes, the moisture content of the clothes to be dried is monitored in real time, and it is determined whether the moisture content belongs to the drying moisture content interval corresponding to cotton and linen clothes. If it is determined that the moisture content of the clothes to be dried belongs to the drying moisture content interval, the current drying program is determined to be ended and the drying is stopped. The drying moisture content interval corresponding to cotton and linen clothes can be [0%, 1%] or [0%, 1.5%], etc.

[0105] If it is determined in step 102 that the material type of the clothes to be dried is non-cotton and linen, since the maximum temperature that non-cotton and linen clothes such as chemical fiber and silk can withstand is the preset temperature, in order to dry the clothes to be dried as quickly as possible while ensuring that the clothes to be dried are not damaged by high temperature, the controller controls the heating device to maintain the surface temperature of the clothes to be dried near the preset temperature until the drying program ends.

[0106] Specifically, the surface temperature of the clothes to be dried is monitored in real time by the temperature sensor. When the surface temperature reaches the preset temperature, the heating device is controlled to stop heating. When the surface temperature of the clothes to be dried is lower than the preset temperature, the heating device is controlled to start heating. In this way, the temperature in the barrel is controlled or maintained by controlling the heating device to be turned on or off, so that the surface temperature of the clothes to be dried is maintained near the preset temperature, until the drying judgment program determines that the moisture content of the clothes to be dried reaches the threshold, and the drying program is controlled to end. This method can reduce the energy consumption of the equipment.

[0107] In the process of drying non-cotton and linen clothes, the moisture content of the clothes to be dried is monitored in real time, and it is determined whether the moisture content belongs to the drying moisture content interval corresponding to the non-cotton and linen clothes. If it is determined that the moisture content of the clothes to be dried belongs to the drying moisture content interval, the current drying program is determined to be ended and the drying is stopped. The drying moisture content interval corresponding to the non-cotton and linen clothes can be [0%, 3%] or [0%, 3.5%], etc.

[0108] In the embodiment of the present application, the heating device in the clothes processing device may include a heating pipe and / or a hot air component, etc. The clothes processing device may also be frequency-converting controlled, and the temperature in the barrel is controlled by controlling the frequency of the compressor.

[0109] If the material type of the clothes to be dried is determined by the second method in step 102, the mapping relationship between each material type and the drying mode is pre-stored in the clothes processing device. After the material type of the clothes to be dried is determined, the drying mode corresponding to the material type of the clothes to be dried is obtained from the mapping relationship between the material type and the drying mode. Then, it is queried whether the drying mode adopted by the current drying program is the same as the drying mode corresponding to the material type of the clothes to be dried. If so, it indicates that the drying mode matching the material type is currently adopted, so the current drying mode is continued to be used to dry the clothes to be dried. If it is queried that the drying mode currently adopted is not the drying mode corresponding to the material type of the clothes to be dried, it indicates that the drying mode currently adopted does not match the material type of the clothes to be dried. In order to avoid the unmatched drying mode from damaging the clothes to be dried, and in order to obtain the best drying effect, the controller switches the current drying mode to the drying mode corresponding to the material type of the clothes to be dried, and adopts the drying mode matching the material type of the clothes to be dried for drying.

[0110] The above drying modes include parameters such as temperature, air volume, rotation speed, etc. When the currently used drying mode is not the drying mode corresponding to the material type of the clothes to be dried, the values ​​of the parameters such as temperature, air volume, rotation speed, etc. in the current drying mode are adjusted to the values ​​of the corresponding parameters in the drying mode corresponding to the material type of the clothes to be dried.

[0111] In the process of drying the clothes to be dried using a drying mode that matches the material type, the moisture content of the clothes to be dried is monitored in real time, and a determination is made as to whether the moisture content belongs to a drying moisture content range corresponding to the material type of the clothes to be dried. If it is determined that the moisture content of the clothes to be dried belongs to the drying moisture content range, the current drying program is determined to be terminated and the drying is stopped.

[0112] In order to facilitate understanding of the drying control method provided in the embodiment of the present application, the following is a description with reference to the accompanying drawings. Figure 4The present invention shows a drying control method for judging whether the material type of the clothes to be dried is cotton and linen. S1: The drying program is started, and the surface temperature of the clothes to be dried is detected in real time by the temperature sensor. S2: It is judged whether the surface temperature of the clothes to be dried is greater than or equal to the preset temperature. If yes, step S3 is executed, and if no, step S1 is returned. S3: The corresponding heating rate of the clothes to be dried is calculated. S4: It is judged whether the material type of the clothes to be dried is cotton and linen according to the heating rate. If yes, step S5 is executed, and if no, step S8 is executed. S5: The heating device is controlled to increase the temperature in the barrel and continue drying. S6: It is judged whether the moisture content in the clothes to be dried reaches the drying moisture content of cotton and linen clothes. If yes, step S7 is executed, and if no, step S5 is returned. S7: Stop drying. S8: The heating device is controlled to maintain the surface temperature of the clothes to be dried at the preset temperature and continue drying. S9: It is judged whether the moisture content in the clothes to be dried reaches the drying moisture content of non-cotton and linen clothes. If yes, step S7 is executed, and if no, step S8 is returned.

[0113] like Figure 5 The present invention shows a drying control method for identifying the material type of clothes to be dried and drying them in a drying mode corresponding to the material type. A1: The drying program is started, and the surface temperature of the clothes to be dried is detected in real time by a temperature sensor. A2: Determine whether the surface temperature of the clothes to be dried is greater than or equal to the preset temperature. If yes, execute step A3; if no, return to step A1. A3: Calculate the heating rate corresponding to the clothes to be dried. A4: Determine the material type of the clothes to be dried according to the rate interval to which the heating rate belongs. A5: Obtain the drying mode corresponding to the material type of the clothes to be dried, and the drying mode adopts the parameter values ​​such as temperature, air volume, and rotation speed corresponding to the material type of the clothes to be dried. A6: Continue to dry the clothes to be dried in this drying mode. A7: Determine whether the moisture content in the clothes to be dried reaches the drying moisture content corresponding to its material type. If yes, execute step A8; if no, return to step A6. A8: Stop drying.
