[0044] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0046] In the related art, due to uneven drying, most parts of the clothes are dried, while dead corners such as cuffs, collars, pockets, etc. are not dried, so that the clothes after drying actually fail to meet the drying requirements, affecting the user experience.

[0047] Based on this, an embodiment of the present application provides a drying control method for a clothes processing device. Before describing the drying control method, the clothes processing device is described first.

[0048] The clothing processing device may be a washer-dryer or a clothes dryer with a drying function, and the clothing processing device may include: an inner drum, a drying tunnel, a heating device, a fan and a condenser; wherein the inner drum is used to load clothing; the heating device and the fan may be arranged in the drying tunnel, the fan is used to circulate and introduce airflow in the drying tunnel, and the heating device is used to heat the airflow in the drying tunnel. Exemplarily, the heating device and the fan may also be arranged outside the drying tunnel and communicate with the drying tunnel, as long as the airflow can be introduced into the drying tunnel. The heating device may be a heating tube, or a heat pump heating system. For example, for a direct-discharge or condensing washer-dryer, the heating device is a heating tube, and for a heat pump washer-dryer, the heating device is a heat pump heating system. The embodiment of the present application does not specifically limit the form of the heating device.

[0049] Exemplarily, the clothing processing device further comprises a box body, which comprises a shell and a front sealing door, a clothing access opening for a user to access clothing is provided on the shell, and the front sealing door can be hinged on the shell to close or open the clothing access opening. The inner drum is located in the shell and has an opening corresponding to the clothing access opening. The inner drum can rotate under the drive of the motor, and can further shake the clothing during the drying process to enhance the uniformity of drying.

[0050] Exemplarily, the clothing processing device also includes: a temperature sensor for detecting the surface temperature value of the clothing in the inner drum of the clothing processing device, which temperature sensor can be fixedly set on the housing of the clothing processing device and is used to detect the temperature values ​​of different parts of the surface of the clothing in the rotating inner drum during the drying process.

[0051] It can be understood that since the inner drum can rotate in the box, thereby driving the clothes in the inner drum to tumble, the temperature sensor fixed to the box can detect the temperature values ​​of different parts of the surface of the clothes in the inner drum.

[0052] It should be noted that the detection point of the temperature sensor should be set towards the direction of the clothes in the inner drum.

[0053] Exemplarily, the temperature sensor may be a thermoelectric pile temperature sensor, which is a pyroelectric infrared sensor based on a thermocouple, and may be composed of two or more thermocouples connected in series, and the thermoelectric potentials output by each thermocouple may be superimposed on each other.

[0054] Exemplarily, the thermopile temperature sensor includes one or more detection points. Taking multiple detection points as an example, the radiation receiving surface of the thermopile temperature sensor is divided into several blocks, each of which is connected to a thermocouple, and they are connected in series to form multiple detection points. Exemplarily, multiple detection points can be arranged based on an array, so as to detect the temperature of the surface of the clothing within the range of the detection points, which is more conducive to detecting whether the clothing is dried evenly based on the temperature of the surface of the clothing.

[0055] For example, Figure 1 As shown, the front sealing door 1 is provided with a receiving groove 2 on one side facing the clothing access opening, and the temperature sensor 3 in the embodiment of the present application can be arranged at the receiving groove 2 to detect the surface temperature of the clothing in the inner drum. Preferably, the receiving groove 2 is arranged at a position on the front sealing door 1 close to the outer periphery of the clothing access opening, so that the receiving groove 2 can avoid the door glass on the rear side of the front sealing door 1.

[0056] Next, based on the aforementioned clothes processing apparatus, a drying control method of the clothes processing apparatus according to an embodiment of the present application is introduced.

[0057] like Figure 2As shown, the drying control method of the clothes processing device in the embodiment of the present application includes:

[0058] Step 201, obtaining the fluctuation of the surface temperature of the clothes in the inner drum of the clothes processing device during the drying process.

[0059] During the drying process, the fan and heating device of the clothing processing equipment are turned on, and the inner drum can also be controlled to rotate at a set speed, for example, alternately forward and reverse, so that the inner drum has the effect of shaking the clothes. In addition to achieving the effect of uniform drying of the clothes, it is also beneficial for the temperature sensor to collect temperature values ​​of different parts of the surface of the clothes.

[0060] Here, the fluctuation of the temperature on the surface of the clothing may be represented by a combination of multiple temperature values ​​of different parts of the surface of the clothing acquired by the temperature sensor at different times.

[0061] It is understandable that for a temperature sensor with multi-point detection, the surface temperature of multiple locations on the surface of the clothing can be obtained each time it is detected, and as the inner drum drives the clothing to turn over, the surface temperature of more locations can be obtained.

[0062] It can be understood that for a single-point detection temperature sensor, as the inner drum drives the clothes to turn over, the surface temperature of different parts of the clothes surface can be obtained based on the continuous detection of the temperature sensor.

[0063] It can be understood that if there are differences in the dryness and wetness of different parts of the clothes, the corresponding surface temperatures will also be different. The detection results of the temperature sensor will appear as a combination of alternating higher temperature values ​​and lower temperature values. The temperature fluctuation is characterized by the combination of this temperature value. Therefore, based on the continuous detection results of the temperature sensor for single-point detection mentioned above or the single or continuous detection results of the temperature sensor for multi-point detection, the fluctuation of the surface temperature of the clothes during the drying process can be obtained.

[0064] Step 202: Determine the dispersion of the fluctuation based on the fluctuation of the surface temperature of the clothing.

[0065] It can be understood that when there is an undried area in the clothes in the inner drum, the temperature value of the undried area will be lower than the temperature value of the drying area. When the clothes rotate in the inner drum, the temperature sensor will continuously detect the temperature values ​​of various parts of the clothes. When the undried area is detected, the temperature value is lower, and when the drying area is detected, the temperature value is higher.

[0066] For example, the data distribution of temperature values ​​is as follows Figure 3 As shown, the value on the horizontal axis represents time in minutes, and the value on the vertical axis represents temperature in degrees Celsius. When there is an undried area, the temperature value data fluctuates greatly due to different detection locations (such as Figure 3When the clothes are completely dried, the temperature of each part of the clothes is basically the same, so the temperature fluctuations tend to be consistent (such as Figure 3 the second half shown).

[0067] Based on this, in an embodiment of the present application, the discreteness of the fluctuation is determined based on the fluctuation of the surface temperature of the clothes, and based on the discreteness, it is judged whether all parts of the clothes have been dried evenly.

[0068] In some embodiments, determining the dispersion of the fluctuation based on the fluctuation of the surface temperature of the clothing includes:

[0069] For the temperature values ​​of different parts of the clothes in the inner drum for a set time, a dispersion representing the temperature fluctuation of the clothes surface is determined based on at least one of the range, the mean deviation, the variance and the standard deviation.

[0070] Here, the range is also called the full range, which refers to the difference between the maximum value and the minimum value in the temperature value of the set time, that is, the interval span between the maximum value and the minimum value in the temperature value obtained within the set time.

[0071] Here, the average difference refers to the arithmetic mean of the absolute value of the deviation between each sample value and the average value in the temperature value of the set time. It comprehensively reflects the degree of change of each temperature value in the whole. The larger the average difference, the greater the degree of change, and vice versa.

[0072] Here, variance refers to the average of the squares of the differences between each sample value and the average of all sample values ​​in the temperature value of a set time, and is used to measure the difference between the source data and the expected value.

[0073] Here, standard deviation refers to the arithmetic square root of the average of the squares of the deviations of the sample values ​​in the temperature value of the set time, which is used to reflect the degree of dispersion of the temperature value distribution. The standard deviation can be calculated based on the sample values ​​or the theoretical distribution of the surface temperature, which are called sample standard deviation and population standard deviation respectively.

[0074] It can be understood that the discreteness of the embodiment of the present application can be determined based on at least one of the aforementioned range, mean deviation, variance and standard deviation, and technical personnel in this field can make a reasonable choice based on demand so that the discreteness can characterize the fluctuation of the surface temperature of the clothing.

[0075] Exemplarily, at least one of the range, mean deviation, variance and standard deviation determined based on the temperature values ​​of different parts within a set time period can be used as a discrete indicator of the set time period, and the discrete indicators of several set time periods are sequentially composed into a one-dimensional array, and the discreteness of the set time period is determined based on the average value of the discrete indicators of the set time period and at least one adjacent set time period in the one-dimensional array, which is more conducive to improving the accuracy of the discreteness calculation and more accurately reflecting the fluctuation of the surface temperature of the clothing.

[0076] Exemplarily, the set time can be reasonably determined based on the rotation speed of the inner drum. For example, the set time can be greater than or equal to the time corresponding to one rotation of the inner drum, so as to collect the temperature value corresponding to the surface of the clothes in one rotation of the inner drum, and determine the corresponding discreteness based on the collected temperature value, and then judge whether the clothes are dried evenly according to the fluctuation of the surface temperature of various parts of the clothes in the inner drum during the drying process.

[0077] Exemplarily, the set duration may be a fixed duration such as 10 seconds, 20 seconds, or 30 seconds, and the embodiments of the present application do not specifically limit this.

[0078] Step 203: determining whether the clothes in the inner drum are dried evenly based on the dispersion.

[0079] Exemplarily, determining whether the clothes in the inner drum are dried evenly based on the dispersion includes:

[0080] Based on the discreteness, the discreteness is compared with a preset discreteness threshold;

[0081] If the discreteness is greater than the discrete threshold, it is determined that the clothes in the inner drum are not dried evenly;

[0082] If the discreteness is less than or equal to the discrete threshold, it is determined that the clothes in the inner drum have been dried evenly.

[0083] It can be understood that the discrete threshold can be reasonably determined based on experiments, or different values ​​can be selected as discrete thresholds according to different clothing materials and / or types, which can be used as a basis for determining whether the clothes in the inner drum are dried evenly. This is conducive to more precise control in the use scenario of classified drying.

[0084] The drying control method of the embodiment of the present application can effectively determine whether the clothes in the inner drum are dried evenly during the drying process, and then can perform drying control based on the result of whether the clothes are dried evenly, so that the drying control of the clothes can meet the actual drying requirements and improve user satisfaction.

[0085] In some embodiments, before determining whether the clothes in the inner drum are dried evenly based on the dispersion, the drying control method further includes:

[0086] Determine whether the overall moisture content of the clothes in the inner drum has reached the drying standard based on the test result of the moisture content of the clothes in the inner drum;

[0087] Accordingly, determining whether the clothes in the inner drum are dried evenly based on the dispersion includes:

[0088] It is determined that the overall moisture content of the clothes in the inner drum has reached the drying standard, and whether the clothes in the inner drum are dried evenly is determined based on the dispersion.

[0089] Exemplarily, the clothing processing device may further include a humidity sensor for detecting the moisture content of the airflow in the inner drum. The clothing processing device may obtain a moisture content detection result based on the detection signal of the humidity sensor, and compare the detection result with a preset moisture content threshold. If the detection result is less than or equal to the moisture content threshold, it is determined that the overall moisture content of the clothes in the inner drum has reached the drying standard, but it cannot be determined whether the clothes are dried evenly. After determining that the overall moisture content of the clothes in the inner drum has reached the drying standard, the clothing processing device may determine whether the clothes in the inner drum are dried evenly based on the discreteness, and perform drying control based on the result of whether the clothes are dried evenly.

[0090] For example, if the clothes processing device determines that the moisture content detection result is greater than the moisture content threshold, it is determined that the overall moisture content of the clothes in the inner drum has not reached the drying standard, and the drying control is continued until it is determined that the overall moisture content of the clothes in the inner drum has reached the drying standard, and whether the clothes in the inner drum are dried evenly is determined based on the discreteness. Here, continuing to maintain the drying control means maintaining the operation of the fan, the operation of the heating device, and the rotation of the inner drum.

[0091] Here, the moisture content threshold can be reasonably determined based on experiments.

[0092] In one embodiment, after determining that the overall moisture content of the clothes in the inner drum has reached the drying standard, the clothing processing device can obtain the temperature values ​​of different parts of the surface of the clothes in the inner drum during the drying process, determine the discreteness characterizing the temperature fluctuation of the clothing surface based on the temperature values ​​of the different parts, and determine whether the clothes in the inner drum are dried evenly based on the discreteness. That is, the clothing processing device can further determine whether the clothes in the inner drum are dried evenly only on the basis of determining that the overall moisture content of the clothes in the inner drum has reached the drying standard. If it is determined that the clothes in the inner drum have been dried evenly, the drying control can be ended, that is, the heating device and the fan are controlled to be turned off, and the inner drum is controlled to stop rotating.

[0093] In some embodiments, the drying control method further includes:

[0094] When it is determined that the clothes in the inner drum have been dried evenly, the drying control ends.

[0095] In some embodiments, the drying control method further includes:

[0096] If it is determined that the clothes in the inner drum are not dried evenly, the running time based on the drying control is compared with the rated drying time;

[0097] If it is determined that the running time is less than the rated drying time, the drying control is continued until the running time reaches the rated drying time or it is determined that the clothes in the inner drum have been dried evenly, and the drying control is ended.

[0098] Here, the rated drying time may be the maximum working time allowed by the drying control.

[0099] The present application is further described in detail below in conjunction with application examples.

[0100] like Figure 4 As shown, the drying control method of the clothes processing device in this application embodiment includes:

[0101] Step 401, drying control.

[0102] Here, the clothes processing device automatically enters the drying control based on the stage of the washing program or based on the user's input command. The drying control refers to controlling the operation of the fan and the heating device and controlling the rotation of the inner drum, for example, alternately rotating forward and reversely at a set speed. At this time, the airflow heated in the drying channel flows into the inner drum, and becomes a humid and hot airflow after heating the clothes. The humid and hot airflow is condensed by the condenser and becomes a dry airflow. The precipitated moisture is collected or directly discharged. The dry airflow is heated again by the heating device and becomes a dry hot airflow and flows into the inner drum to heat the clothes. In this way, the moisture of the clothes is continuously discharged in a cycle to achieve the purpose of drying the clothes.

[0103] Step 402, obtaining the fluctuation of the surface temperature of the clothes in the inner drum.

[0104] Here, the clothes processing device can obtain a combination of temperature values ​​of different parts of the surface of the clothes in the inner drum based on the aforementioned temperature sensor, and determine the fluctuation of the surface temperature.

[0105] Step 403: Determine the dispersion based on the fluctuation of the surface temperature for a set period of time.

[0106] Here, the clothing processing device can determine the discreteness of the temperature values ​​of different surfaces of the clothing in the inner drum for a set time based on the range, mean difference, variance and / or standard deviation to characterize the surface temperature fluctuation of the clothing. For details, please refer to the previous description and will not be repeated here.

[0107] Step 404, determining whether the overall moisture content of the clothes in the inner drum has reached the drying standard, if not, returning to step 401; if yes, executing step 405.

[0108] Here, the clothing processing device can obtain the detection result of the moisture content based on the detection signal of the humidity sensor, and compare the detection result with the preset moisture content threshold. If the detection result is less than or equal to the moisture content threshold, it is determined that the overall moisture content of the clothes in the inner drum has reached the drying standard, and step 405 is executed; if the detection result is greater than the moisture content threshold, it is determined that the overall moisture content of the clothes in the inner drum has not reached the drying standard, and the process returns to step 401 to continue drying control.

[0109] Step 405 , determining whether the clothes in the inner drum are dried evenly, if not, executing step 406 ; if yes, executing step 407 .

[0110] Here, the clothing processing device can compare the determined discreteness with a preset discrete threshold. If the discreteness is greater than the discrete threshold, it is determined that the clothes in the inner drum are not dried evenly, and step 406 is executed; if the discreteness is less than or equal to the discrete threshold, it is determined that the clothes in the inner drum are dried evenly, and step 407 is executed.

[0111] Step 406 , determining whether the drying time reaches the rated drying time, if not, returning to step 401 ; if yes, executing step 407 .

[0112] Here, the clothes processing device determines whether the drying time reaches the rated drying time. If not, it returns to step 401 and continues the drying control. If so, it executes step 407.

[0113] Step 407, ending the drying control.

[0114] Here, the clothing processing device can control the heating device and the fan to turn off, control the inner drum to stop rotating, and exit the drying control.

[0115] It can be understood that the drying control method of this application embodiment, on the basis of determining whether the overall moisture content of the clothes in the inner drum has reached the drying standard, has added a judgment logic of whether the clothes in the inner drum are dried evenly. Therefore, the drying control is terminated only when the overall moisture content of the clothes in the inner drum has reached the drying standard and the clothes are dried evenly or the overall moisture content has reached the drying standard and the drying time has reached the rated drying time. Drying control can be performed based on the result of whether the clothes are dried evenly, so that the drying control of the clothes can meet the actual drying requirements and improve user satisfaction.

[0116] In order to implement the method of the embodiment of the present application, the embodiment of the present application also provides a drying control device of a clothing processing equipment, which corresponds to the drying control method of the above-mentioned clothing processing equipment, and each step in the embodiment of the drying control method of the above-mentioned clothing processing equipment is also fully applicable to the embodiment of the drying control device of the present clothing processing equipment.

[0117] like Figure 5As shown, the drying control device of the clothing processing equipment includes: an acquisition module 501, a first determination module 502 and a second determination module 503; the acquisition module 501 is used to obtain the fluctuation of the surface temperature of the clothes in the inner drum of the clothing processing equipment during the drying process; the first determination module 502 is used to determine the discreteness characterizing the fluctuation based on the fluctuation of the surface temperature of the clothes; the second determination module 503 is used to determine whether the clothes in the inner drum are dried uniformly based on the discreteness.

[0118] It is understandable that the drying control device further includes: a drying control module 504 for drying control. For example, after the drying control is started, the fan and the heating device are controlled to work, and the inner drum is controlled to rotate at a set speed.

[0119] Exemplarily, the acquisition module 501 is specifically used to: acquire a combination of multiple temperature values ​​of different parts of the surface of the clothes in the inner drum based on the temperature sensor, and use the combination as the fluctuation of the surface temperature of the clothes.

[0120] In some embodiments, the first determining module 502 is specifically configured to:

[0121] For the temperature values ​​of different parts of the surface of the clothes in the inner drum for a set time, a dispersion representing the temperature fluctuation of the surface of the clothes is determined based on at least one of the range, the mean deviation, the variance and the standard deviation.

[0122] In some embodiments, the second determining module 503 is specifically configured to:

[0123] Based on the comparison between the discreteness and a preset discrete threshold value;

[0124] If the discreteness is greater than the discrete threshold, it is determined that the clothes in the inner drum are not dried uniformly;

[0125] If the discreteness is less than or equal to the discrete threshold, it is determined that the clothes in the inner drum have been dried evenly.

[0126] In some embodiments, the drying control module 504 is also used to determine whether the overall moisture content of the clothes in the inner drum has reached the drying standard based on the detection result of the moisture content of the clothes in the inner drum; accordingly, the second determination module 503 is used to determine whether the overall moisture content of the clothes in the inner drum has reached the drying standard, and determine whether the clothes in the inner drum are dried evenly based on the discreteness.

[0127] In some embodiments, the drying control module 504 is further used to: determine that the overall moisture content of the clothes in the inner drum has not reached the drying standard, and continue drying control until it is determined that the overall moisture content of the clothes in the inner drum has reached the drying standard.

[0128] In some embodiments, the drying control module 504 is further configured to:

[0129] When it is determined that the clothes in the inner drum have been dried evenly, the drying control is terminated.

[0130] In some embodiments, the drying control module 504 is further configured to:

[0131] If it is determined that the clothes in the inner drum are not dried uniformly, the running time based on the drying control is compared with the rated drying time;

[0132] If it is determined that the operating time is less than the rated drying time, the drying control is continued until the operating time reaches the rated drying time or it is determined that the clothes in the inner drum have been dried evenly, and the drying control is ended.

[0133] In actual application, the acquisition module 501, the first determination module 502, the second determination module 503 and the drying control module 504 can be implemented by a processor in the drying control device of the clothes processing device. Of course, the processor needs to run the computer program in the memory to realize its function.
