For example, in some examples of the present invention, components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present invention.

[0027] See also Figure 1 , the following combination Figure 1 The household appliance 1 provided in the first aspect of the present invention is introduced in detail, and the household appliance 1 includes a display screen 2 and a touch panel. Among them, the display screen 2 can be a TFT (Thin Film Transistor) display screen, and can also be any other type of display screen. The display screen 2 can be used to display the program running status of the household appliance 1 and the operating information of the household appliance 1 such as the fault code, so as to provide intuitive visual data for human-computer interaction; the touch panel is made of a light-transmitting material, such as light-transmitting plastic or glass, and one surface of the touch panel is a touch surface, which faces the user side after installation, and a number of touch buttons are arranged on the touch surface, and the touch buttons are used for operations such as selecting a washing program, adjusting settings and starting.

[0028] The household appliance provided by the present invention also includes a light-emitting component, which is located on the back of the touch panel. The display screen 2 and the light-emitting component are both connected to the control module of the household appliance 1, and the control module can be a control chip, a signal circuit, or the like provided in the household appliance, which can control the operation of the household appliance. In addition, the control module can adjust the color of the light-emitting component according to the background color of the display screen 2, so that the light emitted by the light-emitting component matches the background color. For example, when the background color of the display screen 2 is red, the control module controls the light-emitting component to emit red light. At this time, the red light emitted by the light-emitting component passes through the touch panel, making the touch panel visually present a red effect, thereby matching the red background of the display screen 2 with the touch panel, and visually presenting an overall large-screen effect.

[0029] Next Read Figure 2In some embodiments, the touchpad is disposed on at least one side of the display screen 2. For example, the touchpad can be disposed on the left side of the display screen 2. The touchpad can also be disposed on the right side of the display screen 2. The touchpad can also be disposed one on each of the left and right sides of the display screen 2. Specifically, a first touchpad 3 is disposed on the left side of the display screen 2, and a second touchpad 4 is disposed on the right side of the display screen 2. A first light-emitting component is disposed on the back side of the first touchpad 3, and a second light-emitting component is disposed on the back side of the second touchpad 4. In addition, the first light-emitting component is composed of a first circuit board 5 and a first lamp group, and the first lamp group is disposed on a side of the first circuit board 5 facing the first touchpad 3; the second light-emitting component is composed of a second circuit board 6 and a second lamp group, and the second lamp group is disposed on a side of the second circuit board 6 facing the second touchpad 4.

[0030] Among them, see Figure 3 , the first lamp group is composed of LED lamps 8 (light emitting diodes), and similarly, the second lamp group is also composed of LED lamps 8 (not shown in the attached figure). By controlling the LED lamp 8 bead chips of the three basic colors of red, green and blue in the LED lamp 8, according to the principle of optical three primary colors (that is, mixing the three colors of red, green and blue in a certain proportion), the same color as the background color of the display screen 2 is adjusted. Specifically, after the control system obtains the background color of the background image, it converts the RGB value of the background color (that is, the combination of red (R), green (G), and blue (B)) into an integer color value, where the color value = (65536*Blue) + (256*Green) + (Red), and then controls the first lamp board and the second lamp board to emit light according to the color value corresponding to each color. By converting the RGB value of the background color into a single integer value, it is not only convenient for data storage and recognition, but also can adapt to most control systems.

[0031] It can be understood that since the longer the distance light propagates, the lighter the color of the light, the first light group and the first touch pad 3 in the present application are parallel to each other, the second light group and the second touch pad 4 are parallel to each other, and the distance between the first light group and the first touch pad 3 is equal to the distance between the second light group and the second touch pad 4; in other words, the distance between each point on the first circuit board 5 and the first touch pad 3 is h, and the distance between each point on the second circuit board 6 and the second touch pad 4 is also h, so that the first light group and the second light group can form the same intensity of backlight brightness on the first touch pad 3 and the second touch pad 4 when emitting light of the same brightness.

[0032] See also Figure 2 In some embodiments of the present invention, a coating extension sheet 7 is provided on the front of the first touch panel 3, the second touch panel 4 and the display screen 2. The coating extension sheet 7 can weaken the display difference between the first touch panel 3, the second touch panel 4 and the display screen 2, and realize the overall large-screen display effect;

[0033] The coating extension sheet 7 uses vacuum technology to coat a diffusion film (a kind of optical film) on the surface of the display screen 2, the first touch panel 3, and the second touch panel 4. The diffusion film has a layer of randomly dispersed antistatic particles of micron-level structure. When light passes through the diffusion film, it can play a role in light uniformity, making the light of the display screen 2 and the LED lamp 8 softer.

[0034] The second aspect of the present invention provides a control method for a household appliance, through which a large-screen display effect can be achieved on the control panel of the household appliance 1, that is, the display screen 2 and the touch panel are more integrated in appearance when in use, thereby improving the user experience.

[0035] Specifically, after the user starts the household appliance 1, the display screen 2 of the household appliance 1 will light up and display various information related to the operation of the household appliance 1. The various information related to the operation of the household appliance 1 includes text, numbers, letters and other information indicating the operating status of the household appliance 1 (hereinafter referred to as: operating information). In order to facilitate users to identify these operating information such as text, numbers, letters, etc., it is often necessary to distinguish the color of these operating information from the background color of the display screen 2. For example, the screen of the display screen 2 is displayed in black as a whole, and then the operating information is displayed in white or red. Displaying the display screen 2 in black is similar to displaying a "pure black picture" on the display screen 2, and then displaying the operating information on the upper layer of this "pure black picture".

[0036] According to the control method of the present invention, the "pure black picture" can also be replaced by any other one or several colors of pictures as the background picture. After the background picture is displayed on the display screen 2, the control system of the household appliance 1 obtains the background color of the background picture of the display screen 2, and controls the light-emitting component according to the background color so that the color of the light emitted by the light-emitting component matches the background color.

[0037] In some embodiments of the present invention, the background image may be a single solid color image. For example, the background image may be a single red image. At this time, the control system of the household appliance 1 obtains the background color of the background image as "red", and then the control system controls the light-emitting component to emit red light. At this time, the touch panel appears red, so that the touch panel and the display screen 2 form an organic whole in the eyes of the user, presenting a large-screen display effect.

[0038] According to the control method of the household appliance 1 of the above embodiment of the present invention, the background picture displayed on the display screen 2 can be randomly obtained by the control system from a preset picture set. Among them, the preset picture set can pre-store several different pictures, and the control system selects one of the several different pictures as the background picture of the display screen 2.

[0039] Of course, in some embodiments of the present invention, it is also possible to detect user information and select a specific picture as the background picture of the display screen 2. Specifically, the control system can obtain the user's age group and then select a corresponding background picture according to the user's age group.

[0040] Among them, age group refers to dividing the user's age into different intervals, and then, when the user's age falls within the interval, the style of the background picture suitable for the people of the age range is selected.

[0041] For example, for the age group of 10-15, we define it as the youth group, who usually seek vibrant, fashionable and personalized designs. In order to meet their preferences, the color of the background image can be set to a youthful, energetic and happy style, such as green, pink, etc., to enhance the vitality of the interface.

[0042] In contrast, the age group of 60-70 years old is defined as the elderly group. Design for the elderly should focus on simplicity, legibility and comfort. The control system can choose more stable colors such as black or gray to meet the needs of the elderly. These colors are stable and calm, and can convey a sense of simplicity and classicism.

[0043] In the actual application process, taking into account the preferences and needs of users of different age groups, a more attractive and user-friendly interface can be created. The youth group likes designs that are full of vitality and fashion, so their needs can be met through youthful pictures and lively colors. The elderly prefer simple, easy-to-read and calm designs, so the control system can be selected in suitable colors such as black or gray. It should be noted that in the actual application process, the user's age group can be divided into children, teenagers, young and middle-aged people, the elderly, etc. according to the different ages of the users, and then the background pictures of corresponding styles can be matched for them according to the preferences and needs of the children of different ages. The above implementation method can provide a better user experience while meeting the needs of different user groups.

[0044] It should be noted that the above division of user age groups is only an example and is not intended to limit the present invention. In fact, the division of age groups does not necessarily have to be based on intervals such as 5 or 10 years old. As long as users of different ages are divided into corresponding age groups, each age group can correspond to a background image of a corresponding style.

[0045] In some embodiments of the present invention, the display style of the display screen 2 can also be controlled according to the age group of the user. The display style includes the color of the operation information of the household appliance 1, the font of the text and numbers in the operation information, and the size of the text and numbers. By controlling the display style of the display screen 2 according to the age group of the user, the user experience can be improved, the information transmission effect can be enhanced, and specific functions and content can be provided for users of different age groups. This customized display style can meet the needs of different user groups and improve user satisfaction and participation.

[0046] For example, for teenage users aged 10-15, fashionable, personalized fonts and larger text sizes can be used to cater to their preference for lively, youthful designs. Lively colors such as red, orange, and green can be combined with personalized fonts such as italics and thin circles to create a design that matches their aesthetic needs. In addition, teenage users generally have better eyesight, so smaller font sizes can be selected.

[0047] For elderly users aged 60-70, the design should focus on their vision and comfort. Soft colors such as light blue, light green and beige can be selected to convey a sense of calm, comfort and relaxation. Neutral tones such as beige, light gray, light brown, etc. are also suitable for elderly users, with the characteristics of simplicity and classicism. Pay attention to using clear contrast in the design to ensure that the difference between text and background is obvious so that the elderly can read more easily. At the same time, choosing concise and easy-to-read fonts such as Songti, Arial, Times New Roman, etc. can provide a better reading experience. In addition, since the eyesight of the elderly may be weak, a larger font size should be used.

[0048] By comprehensively considering the needs of different user groups, the design can provide a better user experience for young users and elderly users. For young users, use lively colors and personalized fonts, as well as larger text sizes; while for elderly users, choose soft colors and neutral tones, clear contrast and easy-to-read fonts, as well as larger font sizes. Such a design can meet the preferences of users and provide them with a comfortable and easy-to-use interface.

[0049] In some optional embodiments of the present invention, for some users who live alone or live in the same age group, the age group of the user can be set in advance in the control system, that is, when the user starts the household appliance 1, the household appliance 1 will default to the user's age group being in a certain specific interval. For example, if the user is an elderly person aged 60-70, then after the user sets the household appliance 1, each time the household appliance 1 is started, the control system will automatically select the style of the background picture corresponding to the age group of the elderly, or the display style of the operating information.

[0050] In some embodiments of the present invention, the information displayed on the display screen 2 also includes a foreground pattern. The foreground pattern is displayed on the upper layer of the background image and on the lower layer of the operation information. In other words, the background image and the foreground pattern are both the background of the operation information, so as to avoid the existence of the foreground pattern affecting the user's reading of the operation information of the household appliance 1. The foreground pattern can be selected according to whether the day is a holiday. First, it is necessary to obtain the date of the day, and then determine whether the date is a holiday. If the date is a holiday, select the foreground pattern corresponding to the holiday; if the date is not a holiday, select the foreground pattern suitable for the user according to the age group of the current user. The method of selecting the foreground pattern in this embodiment can enhance the personalization of the interface of the display screen 2 and the sense of user participation.

[0051] Specifically, by obtaining the date of the day, we can use relevant date processing tools or APIs to determine whether the date is a holiday. This can be based on the holiday calendar of a specific region or country, such as traditional holidays, public holidays, etc. If the date is a known holiday, we can select a corresponding foreground pattern based on the holiday. For example, if it is the Spring Festival, we can select foreground patterns related to the Spring Festival, such as the word "Fu", firecrackers, spring couplets, etc., to create a festive atmosphere.

[0052] If the date is not a holiday, a matching foreground pattern can be selected according to the user's age group to meet the user's needs and preferences. According to the user's age group, different groups such as teenagers, adults and the elderly can be divided.

[0053] For example, during holidays, such as the Spring Festival, we can choose foreground patterns related to the Spring Festival, such as festive lanterns, lion dances, etc., to let children feel the festive atmosphere. During non-holidays, we can choose foreground patterns that match the age group. For users in this age group who are children, we can choose some cute cartoon images, animals or children's favorite characters as foreground patterns to increase attractiveness and interactivity.

[0054] On the other hand, for adult users, we can choose foreground patterns according to different age groups and hobbies. For example, for adult users, we can choose some fashionable and modern patterns, such as abstract art, urban scenery, etc., to match their aesthetics and lifestyles. For middle-aged users, we can choose some stable and calm patterns, such as natural scenery, simple geometric shapes, etc., to convey a sense of stability and professionalism.

[0055] Finally, for elderly users, we can choose some simple, clear and easy-to-recognize foreground patterns. For example, we can choose some gentle and friendly patterns such as flowers, natural landscapes, etc. to create a feeling of comfort and relaxation.

[0056] By dynamically selecting foreground patterns that match holidays or user age groups, we can provide users with a personalized interface experience, increase the interface's appeal and user engagement. This design strategy can create a richer, more interesting, and more user-friendly interface based on different contexts and user needs.

[0057] It is worth noting that there may be some text in the foreground pattern. For example, during the Spring Festival, the foreground pattern is set to the word "Fu". However, this word "Fu" is not running information. Therefore, when determining the display style according to the user's age group, the word "Fu" is not changed, and the original style of this word "Fu" is retained. In other words, the text in the foreground pattern is also a type of pattern.

[0058] In some other optional embodiments of the present invention, the user's age group can also be determined based on the user's facial image data. In this case, the household appliance 1 should be provided with a camera 11 or other device capable of acquiring the user's facial image, or the household appliance 1 should be connected to an external camera device. Figure 4 , the specific method is as follows:

[0059] Step 101, acquiring and processing user facial image data.

[0060] In an embodiment of the present application, the built-in camera 11 of the household appliance 1 or the externally connected camera device is used to obtain the image data of the user's face. Preferably, the user can stand in front of the household appliance 1 so that the camera 11 can capture the user's face, which can be a real-time video stream or a static image. Next, the acquired facial image data is subjected to necessary preprocessing operations to improve the accuracy and effect of subsequent processing. The preprocessing may include the following aspects: denoising, using an image denoising algorithm such as a median filter or a Gaussian filter to remove noise from the image so that the image is clearer. Enhance contrast: by adjusting the contrast and brightness of the image, the visibility and details of the image are improved. Convert color image to grayscale image: convert a color facial image to a grayscale image. Converting the image to a grayscale image is to simplify subsequent image processing operations. The grayscale image only contains brightness information, without considering color information, so the amount of calculation can be reduced and processing efficiency can be improved. Common grayscale methods include the average method, weighted average method or method based on human eye perception for converting RGB images to grayscale images. Next, the facial images are normalized in size so that all facial images have the same size. This helps ensure the accuracy and reliability of subsequent face detection and feature extraction algorithms.

[0061] Step 102: perform face detection on the user's facial image data and locate facial features.

[0062] Among them, the facial features refer to the key feature points of the face in the facial image, such as eyes, nose, mouth, etc. Specifically, firstly, the facial image data processed by step 101 is analyzed using a face detection algorithm to determine whether there is a face in the image. Commonly used face detection algorithms include the Viola-Jones algorithm and the Haar cascade detector. These algorithms can determine whether there is a face by detecting the feature pattern in the image. Next, if a face area is found in the face detection, it is necessary to locate the face, that is, to determine the position and bounding box of the face area. Common face positioning algorithms use regression or traditional feature extraction methods, such as cascade classifiers based on Haar features and face positioning based on HOG features. These algorithms can accurately locate the face area according to the features of the face. Finally, once the position of the face area is determined, the key feature points of the face, such as eyes, nose, mouth, etc., need to be located. The positioning of these feature points is very critical for subsequent face feature extraction and age judgment. Commonly used key feature point positioning algorithms include shape model-based methods, deep learning-based methods, etc. These algorithms can locate key feature points of a face by learning the shape patterns of the face or using convolutional neural networks.

[0063] In some embodiments of the present invention, decision tree regression is used to locate key feature points. The model of decision tree regression can be represented as a tree structure consisting of nodes and edges. Each node represents a judgment condition for a feature, and each edge represents a judgment result. The root node represents the initial input feature, and the leaf node represents the final prediction result. Specifically, first, according to a certain indicator (such as information gain or Gini coefficient), the optimal feature is selected as the judgment condition for the current node. Secondly, according to the selected features, the data set is divided into different subsets. Finally, for each subset, the above steps are repeated to generate a subtree. In the present application, decision tree regression can be used to locate key feature points, that is, based on the input user facial image data, a decision tree regression model is constructed to predict the position of the key feature points. The decision tree will judge and branch according to the features of the facial image until it reaches the leaf node and obtains the final prediction result, that is, the position of the key feature point.

[0064] Step 103: extracting a feature vector of the face according to the face features.

[0065] According to the facial feature points located above, facial feature vectors are extracted, and feature extraction algorithms are used to extract feature vectors from facial images. These feature vectors may contain various feature information of the face, such as texture, shape, etc. Specifically, feature extraction algorithms include principal component analysis and local binary patterns. The principal component analysis algorithm can reduce high-dimensional data to a low-dimensional space, thereby extracting the most representative features. In face recognition, the principal component analysis algorithm can convert a facial image into a feature vector, where each dimension represents a principal component, describing different features of the facial image. These feature vectors can be used to identify and compare faces.

[0066] Step 104: Determine the age group of the user based on the extracted feature vector.

[0067] Specifically, first, it is necessary to construct a face database containing facial feature vectors of various age groups in advance. This can be done by collecting and labeling facial images of different age groups, and using the same feature extraction algorithm to obtain their feature vectors. The facial feature vector extracted in step 103 is matched with the feature vector in the face database. Common matching methods include Euclidean distance, cosine similarity, etc. By calculating the similarity between feature vectors, the feature vector in the database that is most similar to the input feature vector can be found. According to the matching results, the feature vector in the database that is most similar to the input feature vector is determined, and its corresponding age information is obtained. In this way, the user's age information can be inferred. It should be noted that the construction of the face database and the matching of the feature vector are based on a large amount of labeled data and corresponding algorithm model training. By continuously accumulating and updating the database, the accuracy and reliability of age inference can be improved.

[0068] According to the output user age information, the user age group is judged, thereby judging the user's age group. In some embodiments of the present invention, the age can be divided into five different stages: children, teenagers, adults, middle-aged people, and the elderly. The user's age information is obtained from the output, and the information can be a specific age value or an age group identifier. According to the set age group division standard, the user's age information is mapped to the corresponding age group. This can be achieved through a series of judgment conditions or mapping rules. In some real-time methods, a table lookup method can be used to map a specific age to a corresponding age group. Finally, based on the judgment or mapping results, the age group to which the user belongs is determined.

[0069] In some embodiments of the present invention, a corresponding background animation can also be displayed on the display screen 2 according to the weather conditions of the day. Among them, the background animation can be located at the upper layer of the operation information of the household appliance 1, or it can be located at the lower layer of the operation information of the household appliance 1. Specifically, the household appliance 1 is connected to the Internet and the weather server to obtain the weather conditions of the day, and the display style is switched accordingly.
