[0063] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the 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.
[0064] It should be noted that although the functional modules are divided in the device schematic diagram, and the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a manner different from the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification and claims and the above-described drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.
[0065] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. 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.
[0066] With the continuous improvement of people's requirements for the quality of life, clothes drying devices have been widely used. At present, when drying clothes, the drying device usually judges the drying degree by obtaining the humidity in the drum, and then controls the drying according to the drying degree. However, different clothes types have different corresponding drying conditions. For example, for clothes with fillers such as down jackets, not only the drying of the surface fabric needs to be considered, but also the drying of the inner core. It is difficult to accurately control the drying according to the humidity in the drum.
[0067] Based on this, the embodiment of the present application proposes a drying control method of a drying device, which can accurately control the drying by performing drying treatment on the clothes to be dried according to the clothes type and the drying degree of the clothes to be dried.
[0068] Reference Figure 1 , Figure 1is a flowchart of a drying control method of a drying apparatus provided by an embodiment of the present application. The drying apparatus comprises a drying assembly, a spectrum acquisition module, and a controller. The drying assembly is configured to perform drying treatment on clothes to be dried. The spectrum acquisition module is configured to acquire spectrum image data of the clothes to be dried in a drying process. The controller is electrically connected to the drying assembly and the spectrum acquisition module. The drying control method is performed by the controller and comprises, but is not limited to, steps S110 to S140.
[0069] In step S110, spectrum image data corresponding to multiple time points acquired by the spectrum acquisition module is obtained. The spectrum image data comprises spectrum images and spectrum data of pixel points on the spectrum images.
[0070] In an embodiment of the present application, the spectrum acquisition module acquires spectrum image data of clothes to be dried in the drying apparatus at certain time intervals. The spectrum image data comprises spectrum image information and spectrum data of pixel points on the spectrum images. Thus, the spectrum acquisition module can transmit the acquired spectrum image data to the controller, so that the controller can obtain spectrum image data corresponding to multiple time points acquired by the spectrum acquisition module.
[0071] In an embodiment of the present application, the spectrum acquisition module can be a spectrum acquisition device. The spectrum acquisition device can acquire spectrum image data based on spectrum imaging technology. Specifically, the spectrum acquisition module can combine spectrum resolution capability and image resolution capability to realize spectrum analysis in spatial dimensions. For example, through multi-spectrum imaging and hyperspectrum imaging, spectrum data of each pixel point on the spectrum image can be obtained, and spectrum image information under multiple spectrum bands can also be obtained.
[0072] In step S120, feature analysis is performed on spectrum image information corresponding to multiple time points to obtain a clothes type of the clothes to be dried.
[0073] In an embodiment of the present application, the spectrum image data acquired at each time point comprises spectrum image information and spectrum data of each pixel point on the spectrum image. Thus, by performing feature analysis on the acquired spectrum image information corresponding to multiple time points, the clothes type of the clothes to be dried can be obtained.
[0074] Referring to Figure 2 , Figure 2 is a flowchart of a step of performing feature analysis on spectrum image information corresponding to multiple time points to obtain a clothes type of clothes to be dried provided by an embodiment of the present application. The step comprises, but is not limited to, steps S210 to S230.
[0075] In step S210, feature analysis is performed on the spectral images at multiple time points to obtain a first volume of the clothes to be dried at a first time point and a second volume of the clothes to be dried at a second time point, wherein the first time point is a start drying time point, and the second time point is a time point corresponding to a preset time period from the first time point.
[0076] In step S220, the volume change of the clothes to be dried is calculated according to the first volume and the second volume of the clothes to be dried.
[0077] In step S230, the clothes type of the clothes to be dried is determined according to the volume change of the clothes to be dried.
[0078] In the embodiments of the present application, feature analysis is performed on the spectral image information at multiple time points, and the volume of the clothes to be dried at each time point is obtained. Thus, the volume change of the clothes to be dried can be obtained according to the volume of the clothes to be dried at each time point.
[0079] For example, it is assumed that the spectral image information at multiple time points obtained by the controller is spectral image information at a t1 time point, spectral image information at a t2 time point, spectral image information at a t3 time point, and spectral image information at a t4 time point. According to the spectral image information at the t1 time point, the first volume of the clothes to be dried in the drum can be obtained. According to the spectral image information at the t1 time point, the first volume of the clothes to be dried in the drum can be obtained. According to the spectral image information at the t4 time point, the fourth volume of the clothes to be dried in the drum can be obtained. According to the first volume and the fourth volume, the volume change of the clothes to be dried can be calculated.
[0080] Specifically, the spectral image information at a first time point is obtained, feature analysis is performed on the spectral image information at the first time point, and the first volume of the clothes to be dried in the drum at the first time point is obtained. The first time point is a start drying time point. The spectral image information at a second time point is obtained, feature analysis is performed on the spectral image information at the second time point, and the second volume of the clothes to be dried in the drum at the second time point is obtained. The second time point is a time point corresponding to a preset time period from the first time point. The difference between the first volume and the second volume is calculated to obtain the volume change of the clothes to be dried. Thus, the clothes type of the clothes to be dried can be determined according to the obtained volume change.
[0081] In the embodiments of the present application, the state of the clothes changes during the drying process. The clothes are more fluffy when dry than when wet, that is, the volume changes correspondingly during the drying process. The volume change degree is different for different clothes types. For clothes without fillers, the volume change is small during the drying process, while for clothes with fillers such as down jackets, the volume change is large during the drying process. Thus, the clothes type of the clothes to be dried can be determined according to the volume change of the clothes to be dried during the drying process.
[0082] Referring to Figure 3 , Figure 3 is a step flow chart provided by the embodiment of the present application for determining the type of the clothes to be dried according to the volume change of the clothes to be dried, including but not limited to steps S310 to S320.
[0083] Step S310, when the absolute value of the volume change of the clothes to be dried is greater than a first preset threshold, it is determined that the clothes to be dried are the first type of clothes;
[0084] Step S320, when the absolute value of the volume change of the clothes to be dried is not greater than the first preset threshold, it is determined that the clothes to be dried are the second type of clothes.
[0085] In the embodiment of the present application, the type of clothes includes the first type of clothes and the second type of clothes. The first type of clothes is clothes containing a filler type, such as a down jacket. The second type of clothes is clothes without a filler type. By judging whether the absolute value of the volume change of the clothes to be dried is greater than the first preset threshold, it is determined whether the clothes to be dried are the first type of clothes or the second type of clothes. Specifically, when the absolute value of the volume change of the clothes to be dried is greater than the first preset threshold, it is determined that the clothes to be dried are the first type of clothes. When the absolute value of the volume change of the clothes to be dried is not greater than the first preset threshold, it is determined that the clothes to be dried are the second type of clothes.
[0086] It should be noted that in the embodiment of the present application, in order to ensure the accuracy of the determination of the type of clothes, the volume change obtained is generally the volume change between the start time of drying and the time corresponding to the preset time period interval from the start time of drying. Then, the volume change is compared with the first preset threshold, so that the type of the clothes to be dried can be accurately determined.
[0087] Step S130, performing feature analysis on the spectral data of the pixel points on the spectral images at multiple time points to obtain the drying degree of the clothes to be dried.
[0088] In the embodiment of the present application, the spectral image data collected at each time point includes spectral image information and spectral data of each pixel point on the spectral image, so that by performing feature analysis on the spectral data of the pixel points on the spectral images at multiple time points, the drying degree of the clothes to be dried can be obtained.
[0089] Referring to Figure 4 , Figure 4 is a step flow chart provided by the embodiment of the present application for performing feature analysis on the spectral data of the pixel points on the spectral images at multiple time points to obtain the drying degree of the clothes to be dried, including but not limited to steps S410 to S440.
[0090] Step S410, generating a color change curve according to the spectral data of the pixel points on the spectral images at multiple time points.
[0091] In the embodiments of the present application, the spectral data of different pixel points on the spectral images at multiple time points is analyzed to obtain the spectral curves of different pixel points at multiple time points, so that the spectral data of different pixel points on the spectral images can be analyzed by using the Lab color space according to the spectral curves of different pixel points at multiple time points, the values corresponding to different wavelength segments in the spectral curves can be converted into Lab values (color values) representing the appearance color of the clothes, the Lab values of each pixel point can be obtained, and the color change curve can be generated according to the Lab values of each pixel point corresponding to multiple time points.
[0092] Referring to Figure 5 , Figure 5 is a step flowchart provided by the embodiments of the present application for generating a color change curve according to the spectral data of pixel points on spectral images at multiple time points, including but not limited to steps S510 to S530.
[0093] Step S510, obtaining the pixel point spectral curves corresponding to multiple time points respectively according to the spectral data of the pixel points on the spectral images at multiple time points;
[0094] Step S520, converting the values corresponding to different wavelength segments in the pixel point spectral curves into color values representing the appearance color of the clothes to obtain the pixel point color values corresponding to multiple time points respectively;
[0095] Step S530, generating a color change curve according to the pixel point color values corresponding to multiple time points respectively.
[0096] In the embodiments of the present application, the spectral data of pixel points on spectral images at multiple time points is obtained to obtain the pixel point spectral curves corresponding to multiple time points respectively. The values corresponding to different wavelength segments in the pixel point spectral curves are converted into color values representing the appearance color of the clothes to obtain the pixel point color values corresponding to multiple time points respectively. Thus, the color change curve can be generated according to the pixel point color values corresponding to multiple time points respectively.
[0097] Exemplarily, it is assumed that the spectral data of the pixel points on the spectral images at multiple time instants obtained by the controller are respectively the spectral data of the pixel points on the spectral image at the first time instant t1, the spectral data of the pixel points on the spectral image at the second time instant t2, the spectral data of the pixel points on the spectral image at the third time instant t3, and the spectral data of the pixel points on the spectral image at the fourth time instant t4. According to the spectral data of the pixel points on the spectral image at the first time instant t1, the spectral curves of the pixel points on the spectral image at the first time instant t1 can be obtained. For the spectral curves of the pixel points, the values corresponding to different wavelength segments in the spectral curves are converted into Lab values representing the appearance colors of the clothes, so that the Lab values of the pixel points at the first time instant t1 can be obtained. Similarly, for the spectral curves of the pixel points on the spectral image at the second time instant t2, the Lab values of the pixel points at the second time instant t2 can be obtained. For the spectral curves of the pixel points on the spectral image at the third time instant t3, the Lab values of the pixel points at the third time instant t3 can be obtained. For the spectral curves of the pixel points on the spectral image at the fourth time instant t4, the Lab values of the pixel points at the fourth time instant t4 can be obtained. Thus, according to the Lab values of the pixel points at the first time instant t1, the Lab values of the pixel points at the second time instant t2, the Lab values of the pixel points at the third time instant t3, and the Lab values of the pixel points at the fourth time instant t4, the Lab value change curves corresponding to the pixel points, i.e., the color change curves corresponding to the pixel points, can be obtained. Then, the color change curves corresponding to the pixel points are averaged to obtain a final color change curve.
[0098] It should be noted that the values corresponding to different wavelength segments in the spectral curves are the ordinate values corresponding to different wavelength segments in the spectral curve diagram obtained by the spectral acquisition module. When the ordinate is transmittance, the transmittance corresponding to different wavelength segments in the spectral curves is converted into the Lab values representing the appearance colors of the clothes. When the ordinate is absorption, the absorption corresponding to different wavelength segments in the spectral curves is converted into the Lab values representing the appearance colors of the clothes. When the ordinate is intensity, the intensity corresponding to different wavelength segments in the spectral curves is converted into the Lab values representing the appearance colors of the clothes. When the ordinate is relative intensity, the relative intensity corresponding to different wavelength segments in the spectral curves is converted into the Lab values representing the appearance colors of the clothes.
[0099] In an embodiment of the present application, based on the spectral data of each pixel point on the spectral images at multiple time instants, the spectral curves of each pixel point at multiple time instants are obtained. The values corresponding to different wavelength segments in the spectral curves of each pixel point are converted into Lab values representing the appearance colors of the clothes, so that the Lab values of each pixel point at multiple time instants are obtained. According to the Lab values of each pixel point at multiple time instants, the Lab value change curves of each pixel point can be generated. Then, the Lab value change curves of each pixel point are averaged to obtain the color change curves corresponding to multiple time instants.
[0100] In an embodiment of the present application, the spectral data of the target pixel points on the spectral images at multiple time points can also be used to obtain the spectral curves of the target pixel points at the multiple time points respectively. The values corresponding to different wavelength ranges in the spectral curves of the target pixel points are converted into Lab values representing the appearance color of the clothes to obtain the Lab values of the target pixel points at the multiple time points respectively. The Lab value change curves of the target pixel points can be generated according to the Lab values of the target pixel points at the multiple time points respectively. The color change curves corresponding to the multiple time points can be obtained by averaging the Lab value change curves of the target pixel points.
[0101] In step S420, the color change amplitude curve is calculated according to the color change curve.
[0102] In the embodiment of the present application, the color change amplitude curve can be obtained by deriving the color change curve after obtaining the color change curve.
[0103] In step S430, the color distribution uniformity at the current time is obtained according to the spectral data of the pixel points on the spectral image at the current time.
[0104] In the embodiment of the present application, the spectral curves of different pixel points at the current time can be obtained according to the spectral data of different pixel points on the spectral image at the current time, so that the values corresponding to different wavelength ranges in the spectral curves can be converted into Lab values representing the appearance color of the clothes according to the spectral curves of different pixel points at the current time, and the Lab values of each pixel point can be obtained, so that the color distribution uniformity at the current time can be obtained according to the Lab values of each pixel point at the current time.
[0105] Reference Figure 6 , Figure 6 FIG. 6 is a flowchart of a step of obtaining the color distribution uniformity at the current time according to the spectral data of the pixel points on the spectral image at the current time according to an embodiment of the present application, including but not limited to steps S610 to S630.
[0106] In step S610, the spectral curves of multiple pixel points at the current time are obtained according to the spectral data of the pixel points on the spectral image at the current time.
[0107] In step S620, the values corresponding to different wavelength ranges in the spectral curves of the multiple pixel points are converted into color values representing the appearance color of the clothes to obtain the color values of the multiple pixel points at the current time.
[0108] In step S630, the color distribution uniformity at the current time is obtained according to the color values of the multiple pixel points at the current time.
[0109] In the embodiment of the present application, according to the spectral data of the pixel points on the spectral image at the current time, a plurality of pixel point spectral curves at the current time can be obtained. The values corresponding to different wavelength segments in the plurality of pixel point spectral curves are converted into color values representing the appearance color of the clothes, and the Lab values of the plurality of pixel points corresponding to the current time can be obtained. Thus, according to the Lab values of the plurality of pixel points corresponding to the current time, the color distribution uniformity at the current time can be obtained.
[0110] Exemplarily, the controller can obtain the spectral image data collected by the spectral collection module at the current time, so that by performing feature analysis on the spectral data of the pixel points on the spectral image at the current time, the spectral curve of each pixel point on the spectral image at the current time can be obtained. For the spectral curve of each pixel point, the values corresponding to different wavelength segments are converted into Lab values representing the appearance color of the clothes, so that the Lab values of each pixel point at the current time can be obtained. Further, the variance of the Lab values of each pixel point at the current time is calculated, and the color distribution uniformity at the current time can be obtained. The smaller the variance is, the more uniform the color distribution uniformity is. That is, the color distribution uniformity can be represented by the variance.
[0111] Similarly, in the embodiment of the present application, based on the spectral data of each pixel point on the spectral image at the current time, the spectral curve of each pixel point corresponding to the current time is obtained. The values corresponding to different wavelength segments in the spectral curve of each pixel point are converted into Lab values representing the appearance color of the clothes, and the Lab values of each pixel point corresponding to the current time are obtained. The variance of the Lab values of each pixel point at the current time is calculated, and the color distribution uniformity at the current time can be obtained. Based on the spectral data of a plurality of target pixel points on the spectral image at the current time, the spectral curve of each target pixel point corresponding to the current time can be obtained. The values corresponding to different wavelength segments in the spectral curve of each target pixel point are converted into Lab values representing the appearance color of the clothes, and the Lab values of each target pixel point corresponding to the current time are obtained. The variance of the Lab values of each target pixel point at the current time is calculated, and the color distribution uniformity at the current time can be obtained.
[0112] In step S440, the drying degree of the clothes to be dried is obtained according to the color change amplitude curve and / or the color distribution uniformity at the current time.
[0113] In the embodiment of the present application, for the clothes without fillers, the smaller and more stable the color change range is, the higher the drying degree of the clothes is. For the clothes with fillers, not only the drying of the surface fabric is considered, but also the drying of the inner core is considered. That is, for the clothes with fillers, whether the color change range is smaller and more stable and whether the color distribution uniformity at the current moment is uniform are jointly determined to determine the drying degree. In the embodiment of the present application, after the color change curve and the color distribution uniformity at the current moment are obtained, the drying degree can be determined according to the color change range curve, or the drying degree can be determined according to the color distribution uniformity at the current moment, or the drying degree can be determined according to the color change range curve and the color distribution uniformity at the current moment.
[0114] With reference to Figure 7 , Figure 7 is a step flowchart provided by the embodiment of the present application for obtaining the drying degree of the clothes to be dried according to the color change range curve and / or the color distribution uniformity at the current moment, including but not limited to steps S710 to S750.
[0115] Step S710, when the clothes type is the first type of clothes, obtaining a first color change range value at the previous moment and a second color change range value at the current moment according to the color change range curve;
[0116] Step S720, calculating a first difference value of the first color change range value and the second color change range value;
[0117] Step S730, judging whether the first color change range value is greater than the second color change range value and whether the first difference value is less than a first preset value, and judging whether the color distribution uniformity at the current moment is less than a second preset value;
[0118] Step S740, when the first color change range value is greater than the second color change range value, the first difference value is less than the first preset value, and the color distribution uniformity at the current moment is less than the second preset value, determining that the drying degree of the clothes to be dried is dried;
[0119] Step S750, when the first color change range value is not greater than the second color change range value, or the first difference value is not less than the first preset value, or the color distribution uniformity at the current moment is not less than the second preset value, determining that the drying degree of the clothes to be dried is not dried.
[0120] In the embodiments of the present application, when the clothes type of the clothes to be dried is the first clothes type, i.e., when the clothes to be dried are clothes containing a filler type, the first color change amplitude value at the previous time and the second color change amplitude value at the current time are obtained according to the color change amplitude curve. Thus, according to the first color change amplitude value and the second color change amplitude value, the first difference value of the first color change amplitude value and the second color change amplitude value can be calculated. Thus, by judging whether the first color change amplitude value is greater than the second color change amplitude value and whether the first difference value is less than the first preset value, and judging whether the color distribution uniformity at the current time is less than the second preset value, it can be determined whether the drying degree of the clothes to be dried is dried or not dried. Specifically, when the first color change amplitude value is greater than the second color change amplitude value, and the first difference value is less than the first preset value, and the color distribution uniformity at the current time is less than the second preset value, it is determined that the drying degree of the clothes to be dried is dried. When the first color change amplitude value is not greater than the second color change amplitude value, or the first difference value is not less than the first preset value, or the color distribution uniformity at the current time is not less than the second preset value, it is determined that the drying degree of the clothes to be dried is not dried.
[0121] Referring to Figure 8 , Figure 8 is another step flowchart provided by the embodiments of the present application for obtaining the drying degree of the clothes to be dried according to the color change amplitude curve and / or the color distribution uniformity at the current time, including but not limited to steps S810 to S850.
[0122] Step S810, when the clothes type is the second clothes type, the first color change amplitude value at the previous time and the second color change amplitude value at the current time are obtained according to the color change amplitude curve;
[0123] Step S820, the first difference value of the first color change amplitude value and the second color change amplitude value is calculated;
[0124] Step S830, judging whether the first color change amplitude value is greater than the second color change amplitude value and whether the first difference value is less than the first preset value;
[0125] Step S840, when the first color change amplitude value is greater than the second color change amplitude value, and the first difference value is less than the first preset value, it is determined that the drying degree of the clothes to be dried is dried;
[0126] Step S850, when the first color change amplitude value is not greater than the second color change amplitude value, or the first difference value is not less than the first preset value, it is determined that the drying degree of the clothes to be dried is not dried.
[0127] In the embodiment of the present application, when the clothes type of the clothes to be dried is the second clothes type, i.e., when the clothes to be dried are clothes without fillers, the first color change amplitude value at the previous time and the second color change amplitude value at the current time are obtained according to the color change amplitude curve. Thus, according to the first color change amplitude value and the second color change amplitude value, the first difference value between the first color change amplitude value and the second color change amplitude value can be calculated. Thus, by judging whether the first color change amplitude value is greater than the second color change amplitude value and whether the first difference value is less than the first preset value, it can be determined whether the drying degree of the clothes to be dried is dried or not dried. Specifically, when the first color change amplitude value is greater than the second color change amplitude value and the first difference value is less than the first preset value, it is determined that the drying degree of the clothes to be dried is dried. When the first color change amplitude value is not greater than the second color change amplitude value or the first difference value is not less than the first preset value, it is determined that the drying degree of the clothes to be dried is not dried.
[0128] In the embodiment of the present application, when the clothes to be dried are the first clothes type, the drying degree of the clothes to be dried can be determined according to the color change amplitude curve and the color distribution uniformity at the current time. When the clothes to be dried are the second clothes type, the drying degree of the clothes to be dried can be determined according to the color change amplitude curve.
[0129] In step S140, the drying assembly is controlled to perform drying treatment on the clothes to be dried according to the clothes type and the drying degree of the clothes to be dried.
[0130] In the embodiment of the present application, after the clothes type and the drying degree of the clothes to be dried are determined, the drying assembly can be controlled to perform drying treatment on the clothes to be dried by judging whether the current drying degree of the corresponding clothes type meets the drying completion condition.
[0131] Reference Figure 9 , Figure 9 is a step flow chart provided by the embodiment of the present application for controlling the drying assembly to perform drying treatment on the clothes to be dried according to the clothes type and the drying degree of the clothes to be dried, and includes but is not limited to steps S910 to S930.
[0132] In step S910, it is judged whether the current drying degree of the clothes to be dried meets the drying completion condition corresponding to the clothes type.
[0133] In step S920, when the current drying degree of the clothes to be dried meets the drying completion condition corresponding to the clothes type, the drying assembly is controlled to end the drying treatment on the clothes to be dried.
[0134] In step S930, when the current drying degree of the clothes to be dried does not meet the drying completion condition corresponding to the clothes type, the drying assembly is controlled to continue the drying treatment on the clothes to be dried.
[0135] In the embodiments of the present application, when the clothes to be dried are the first type of clothes, i.e., when the clothes to be dried are clothes of the type containing fillers, the drying completion condition corresponding to the first type of clothes is that the first color change amplitude value is greater than the second color change amplitude value, the first difference value is less than the first preset value, and the color distribution uniformity at the current time is less than the second preset value. When the clothes to be dried are the second type of clothes, i.e., when the clothes to be dried are clothes of the type not containing fillers, the drying completion condition corresponding to the second type of clothes is that the first color change amplitude value is greater than the second color change amplitude value, and the first difference value is less than the first preset value. It can be seen that the drying completion conditions corresponding to different types of clothes are different. Therefore, after obtaining the type of clothes to be dried and the drying degree, it is necessary to determine whether the current drying degree of the clothes to be dried meets the drying completion condition corresponding to the type of clothes to control the drying. Specifically, when the clothes to be dried are the first type of clothes, it is determined whether the current drying degree meets the drying completion condition corresponding to the first type of clothes, i.e., it is determined whether the first color change amplitude value is greater than the second color change amplitude value, the first difference value is less than the first preset value, and the color distribution uniformity at the current time is less than the second preset value. If the first color change amplitude value is greater than the second color change amplitude value, the first difference value is less than the first preset value, and the color distribution uniformity at the current time is less than the second preset value, it is determined that the current drying degree of the clothes to be dried meets the drying completion condition corresponding to the first type of clothes, and the controller controls the drying assembly to end the drying process of the clothes to be dried. If the first color change amplitude value is not greater than the second color change amplitude value, or the first difference value is not less than the first preset value, or the color distribution uniformity at the current time is not less than the second preset value, it is determined that the current drying degree of the clothes to be dried does not meet the drying completion condition corresponding to the first type of clothes, and the controller controls the drying assembly to continue the drying process of the clothes to be dried. Similarly, when the clothes to be dried are the second type of clothes, it is determined whether the current drying degree meets the drying completion condition corresponding to the second type of clothes, i.e., it is determined whether the first color change amplitude value is greater than the second color change amplitude value and the first difference value is less than the first preset value. If the first color change amplitude value is greater than the second color change amplitude value, and the first difference value is less than the first preset value, it is determined that the current drying degree of the clothes to be dried meets the drying completion condition corresponding to the second type of clothes, and the controller controls the drying assembly to end the drying process of the clothes to be dried. If the first color change amplitude value is not greater than the second color change amplitude value, or the first difference value is not less than the first preset value, it is determined that the current drying degree of the clothes to be dried does not meet the drying completion condition corresponding to the second type of clothes, and the controller controls the drying assembly to continue the drying process of the clothes to be dried.
