Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Currently, existing solutions primarily rely on manual experience to place tableware. Users need to decide the placement and method of tableware based on their own experience and judgment. This method requires users to have a certain level of experience and skill, and is easily influenced by personal factors, leading to improper placement, which affects the dishwasher's cleaning performance and space utilization.

[0021] However, existing solutions have several problems in this area. First, due to a lack of scientific and reasonable guidance, users often rely on experience when placing dishes, which can easily lead to improper placement, wasting dishwasher space and resulting in poor cleaning performance. Second, existing solutions cannot adjust the placement of dishes according to different parameters (such as size, shape, depth, degree of soiling, quantity, etc.), thus failing to achieve efficient use of the dishwasher's internal space and optimal cleaning results. Finally, existing solutions require manual operation, which is cumbersome and results in a poor user experience.

[0022] Based on this, the present invention provides a method for placing tableware in a dishwasher and a dishwasher, specifically a method for controlling the placement of tableware based on image recognition and a dishwasher, which can improve the space utilization and cleaning effect of the dishwasher and enhance the user experience.

[0023] To facilitate understanding of this embodiment, a method for arranging tableware in a dishwasher disclosed in this embodiment of the invention will be described in detail first.

[0024] Example 1: This invention provides a method for arranging tableware in a dishwasher, see below. Figure 1 The flowchart shown illustrates a method for arranging tableware in a dishwasher, which includes the following steps: Step S102: Obtain an image including at least one piece of tableware to be placed.

[0025] In this embodiment, the user can take pictures of the tableware. For example, the user can bind the dishwasher product through a mobile APP (Application). The user only needs to take pictures of the used tableware on the table and then upload the pictures to the APP.

[0026] Step S104: Perform image recognition on the image to obtain the parameters of the tableware; wherein, the parameters of the tableware include: size, shape, depth, degree of dirtiness, type and quantity.

[0027] In this embodiment, image recognition technology can be used to identify parameters such as the size, shape, depth, degree of soiling, type, and quantity of the tableware from the image. Specifically, the app can utilize image recognition technology to identify and analyze different parameters of the tableware, such as size, shape, depth, degree of soiling, type, and quantity.

[0028] Step S106: Determine the arrangement of the tableware in the dishwasher based on the tableware parameters.

[0029] In this embodiment, based on the parameters of the tableware obtained from image recognition, the algorithm of the APP calculates the required placement space for each piece of tableware, and further determines the placement method of each piece of tableware in the dishwasher based on the required placement space. This algorithm can consider different parameters of the tableware to determine the most reasonable placement method, thereby achieving efficient use of the dishwasher's internal space and optimal washing results.

[0030] Step S108: Based on the arrangement of the tableware, project the tableware onto the dishwasher rack.

[0031] In this embodiment, the app can intelligently guide the user to place the tableware on the dishwasher shelves (e.g., upper, middle, and lower shelves) based on how the tableware is arranged. This intelligent guidance not only simplifies the operation process and improves the user experience, but also avoids the cumbersome problem of manual operation required by existing solutions.

[0032] In this embodiment, a projection method can be used to guide the user to place the tableware on the upper, middle, and lower shelves respectively. The projection device used can be a laser projector, which can project the calculated optimal placement scheme onto each shelf.

[0033] Furthermore, this embodiment can guide users to place tableware scientifically and reasonably, avoiding space waste and poor cleaning results caused by users placing tableware based on experience. At the same time, adjusting the placement of tableware according to its different parameters can achieve efficient use of the dishwasher's internal space and optimal cleaning results.

[0034] This invention provides a method for placing tableware in a dishwasher. The method involves acquiring an image including at least one piece of tableware to be placed; performing image recognition on the image to obtain parameters of the tableware, including size, shape, depth, degree of soiling, type, and quantity; determining the placement method of the tableware in the dishwasher based on these parameters; and projecting the tableware onto the dishwasher rack based on the placement method. This method provides scientific and reasonable guidance, avoiding the problems of wasted dishwasher space and poor cleaning results caused by users placing tableware based on experience. The placement method can be adjusted according to different tableware parameters, achieving rational utilization of the dishwasher's internal space and optimal cleaning effect. It also simplifies the operation process, improves user experience, and avoids the tedious problem of repeated attempts required by existing solutions when tableware is placed incorrectly.

[0035] The method described in this embodiment has wide applications in fields such as smart home devices, dishwasher technology, and image processing technology. Firstly, in the field of smart home devices, this embodiment guides users to correctly place tableware using image recognition technology, which not only improves the space utilization and cleaning effect of the dishwasher but also enhances the user experience. With the increasing popularity of smart homes, users have higher and higher demands for intelligence and convenience, and this embodiment perfectly aligns with this trend, enjoying broad market demand.

[0036] Secondly, in the field of dishwasher technology, this embodiment uses an algorithm to calculate the required placement space for the dishes to be washed and arranges them rationally according to different parameters, thereby achieving the best washing effect. This not only improves the efficiency of the dishwasher but also extends its service life, meeting the market demand for efficient and energy-saving dishwashers.

[0037] Finally, in the field of image processing technology, this embodiment achieves intelligent identification and spatial layout optimization of tableware through steps such as mobile phone photography, APP uploading, and image recognition. The application of this technology not only improves the application level of image processing technology in the smart home field but also promotes the development of the smart home industry. In general, with the development of technology and the improvement of people's living standards, the demand for intelligence, convenience, and efficiency is receiving increasing attention. This embodiment, through image recognition technology and algorithm calculation, achieves the rational utilization of the dishwasher's internal space and optimal cleaning effect, meeting the market demand for smart home devices and possessing broad application prospects and market demand.

[0038] Example 2: This embodiment provides another method for arranging tableware in a dishwasher. This method is implemented based on the above embodiment, focusing on the specific method of determining the arrangement of tableware in the dishwasher. See also... Figure 2The flowchart shows another method for arranging tableware in a dishwasher, which includes the following steps: Step S202: Obtain an image including at least one piece of tableware to be placed.

[0039] In some embodiments, an image of a dining table may be acquired; wherein, tableware to be placed is laid flat on the dining table.

[0040] See also Figure 3 The diagram illustrates a method for arranging dishes in a dishwasher. Users first need to download and install the dishwasher's app for the specified brand, and then bind the dishwasher through the app's interface. The binding process is simple and easy: first, put the product in a discovered state; once the app detects the product, follow the app's network connection guide to connect the product to the network.

[0041] After using the tableware, users should simply tidy up the tableware without washing it, and then use the camera function of the mobile app to take a picture of the tableware above the table. When taking the picture, ensure the tableware is clearly visible in the frame and avoid obstructing it as much as possible.

[0042] After taking the photo, the user uploads the picture of the tableware to the linked dishwasher app. Uploads can be made via wireless network connections, such as WiFi (mobile hotspot) or mobile data, or via wired network connections, such as USB (Universal Serial Bus).

[0043] Step S204: Perform image recognition on the image to obtain the parameters of the tableware; wherein, the parameters of the tableware include: size, shape, depth, degree of dirtiness, type and quantity.

[0044] like Figure 3 As shown, the app can use its built-in image recognition technology to identify and analyze different parameters of tableware, such as size, shape, depth, degree of soiling, type, and quantity. The recognition process is fast and accurate, usually completed within a few seconds.

[0045] This embodiment provides an image recognition technology: by binding the dishwasher to a mobile app, the user only needs to take a photo of the used tableware on the table and then upload the photo to the app. The app uses image recognition technology to identify and analyze different parameters of the tableware, such as size, shape, depth, and degree of soiling.

[0046] Step S206: Determine the placement space of the tableware based on the tableware parameters, and determine the placement method of the tableware in the dishwasher based on the placement space of the tableware.

[0047] like Figure 3As shown, this embodiment can perform intelligent calculations and solution generation. Based on the structured data output by the image recognition module (including parameters such as the size, shape, depth, degree of soiling, type, and quantity of tableware), the intelligent algorithm engine within the system will perform the following core calculations and decisions 1-3 for spatial calculations: In some embodiments, it can be determined whether the number of tableware exceeds the preset maximum capacity of a single dishwasher wash; if so, the washing order of the tableware is determined based on the degree and type of soiling; the tableware is divided into multiple washing batches based on the washing order, and the arrangement of the tableware in each washing batch in the dishwasher is determined; wherein the number of tableware in each washing batch is less than or equal to the maximum capacity.

[0048] like Figure 3 As shown, the core calculation and decision 1, washing batch planning: If the total capacity of the identified tableware exceeds the maximum capacity of a single wash, the algorithm will intelligently plan a batch washing scheme based on the degree and type of dirt on the tableware (for example, prioritizing heavily soiled tableware), and inform the user of the list of tableware to be processed in this wash.

[0049] In some embodiments, a three-dimensional spatial model of the dishwasher's internal cavity can be constructed, and the position and geometric constraints of the dishwasher's internal cavity components can be imported into the three-dimensional spatial model; wherein, the components of the dishwasher's internal cavity include: shelves and spray arms; the three-dimensional spatial model is divided into multiple placement areas by a spatial optimization algorithm; and the optimal placement position and posture of the tableware in the placement area is determined by a pose determination algorithm based on the placement space of the tableware.

[0050] Core Calculation and Decision Making 2: Calculation of Optimal Placement Scheme (1) Spatial modeling: The algorithm first constructs a three-dimensional spatial model of the dishwasher's internal cavity and imports the precise positions and geometric constraints of components such as shelves and spray arms.

[0051] (2) Adaptive partitioning: The algorithm does not fix "various types of areas", but dynamically allocates placement areas for tableware of different sizes and shapes according to the actual situation of the tableware to be washed.

[0052] The core of the adaptive partitioning in this embodiment is a space optimization algorithm (such as drawing on two-dimensional / three-dimensional bin packing algorithms), with the objective function being to maximize space utilization and washing uniformity.

[0053] (3) Precise pose determination: The algorithm calculates the optimal placement position (coordinates) and orientation (pose) of each piece of tableware on the shelf.

[0054] In some embodiments, the pose determination algorithm is used to determine the optimal placement position and posture of the tableware in the placement area based on a preset decision criterion; wherein the decision criterion is based on the position and posture settings of the tableware after placement.

[0055] The pose determination algorithm's decision-making criteria include, but are not limited to: avoiding obstruction: ensuring that tableware does not block the water path of the spray arm, guaranteeing that the water flow can fully rinse all surfaces of all tableware. Stability: ensuring that tableware is stable after placement and will not tip over or collide during washing. Maximizing efficiency: compact arrangement to reduce useless space. Special treatment: for deeply stained tableware, directing it towards the main spray direction or allocating it to an area with stronger water flow.

[0056] This embodiment provides an algorithmic calculation technique: based on image recognition results, the app uses an algorithm to calculate the required placement space for each piece of tableware. This algorithm considers different parameters of the tableware to determine the most reasonable placement method, thereby achieving efficient use of the dishwasher's internal space and optimal washing results.

[0057] Step S208: Based on the arrangement of the tableware, project the tableware onto the dishwasher rack.

[0058] In some embodiments, projection control parameters can be generated based on the optimal placement and orientation of the tableware; the projection device is controlled based on the projection control parameters so that the projection device projects the tableware onto the rack of the dishwasher and projects the outline of the tableware or a guide graphic of the tableware; wherein the guide graphic is used to indicate the optimal placement position.

[0059] In some embodiments, the outline of the tableware or the guide graphic of the tableware can be generated based on the image of the tableware; the projection device can be controlled to project the outline of the tableware or the guide graphic of the tableware based on the projection control parameters.

[0060] Core Computation and Decision 3, Projection Instruction Generation: The algorithm generates corresponding projection control parameters for the final placement and orientation of each piece of tableware. These parameters guide the laser projector to project the outline or shape of the tableware at the corresponding position on the dishwasher shelf with high precision. This can be a circle of a plate (i.e., the outline of the tableware) or an arrow indicating the direction of a spoon to indicate the optimal placement of the plate (i.e., the guide graphic of the tableware).

[0061] In this embodiment, based on the algorithm's calculations, the app intelligently guides the user to place the tableware on the upper, middle, and lower racks of the dishwasher. This intelligent guidance not only simplifies the operation process and improves the user experience but also avoids the cumbersome problem of manual operation required by existing solutions.

[0062] This embodiment provides an intelligent guidance technology: based on algorithm calculations, the app intelligently guides the user to place the tableware on the upper, middle, and lower racks of the dishwasher. This intelligent guidance not only simplifies the operation process and improves the user experience, but also avoids the cumbersome problem of manual operation required by existing solutions.

[0063] This embodiment also provides a space optimization technology: by guiding the scientific and reasonable placement of tableware, this embodiment can avoid the problems of wasted space and poor cleaning effect caused by users placing tableware based on experience. At the same time, by adjusting the placement of tableware according to different parameters, the internal space of the dishwasher can be rationally utilized and the cleaning effect can be optimized.

[0064] In some embodiments, the dishwasher can also be started to perform a cleaning operation; during the cleaning operation, the parameters of the dishwasher are adjusted based on the parameters of the tableware; wherein the parameters of the dishwasher include: spray intensity and temperature.

[0065] Once all the dishes are placed in the dishwasher, the user starts the washing cycle. During the washing process, the dishwasher adjusts parameters such as spray intensity and temperature based on the different characteristics of the dishes to achieve the best cleaning results. This method allows users to easily make efficient use of the dishwasher's internal space and achieve optimal cleaning performance, while simplifying the operation and improving the user experience.

[0066] In summary, the methods provided in the embodiments of the present invention mainly provide the following: (1) Image recognition technology: Based on the image taken by the user, the parameters of the tableware can be identified and analyzed. Different parameters of the tableware, such as size, shape, depth, degree of dirt, type, quantity, etc., can be identified and analyzed.

[0067] (2) Algorithm calculation method: Based on the image recognition results, the APP calculates the length of the space required for each piece of tableware through the algorithm, taking into account different parameters of the tableware to determine the most reasonable placement method, thereby realizing the reasonable use of the internal space of the dishwasher and the best cleaning effect.

[0068] (3) Intelligent guidance technology: Based on the algorithm calculation results, the APP generates placement pictures and intelligently guides the user to place the tableware on the upper, middle and lower racks of the dishwasher. This intelligent guidance not only simplifies the operation process but also improves the user experience.

[0069] (4) Projection technology: The projection method guides users to place the tableware on the upper shelf, middle shelf and lower shelf respectively. The projection device used is a laser projector, which can project the calculated best placement scheme onto each shelf.

[0070] (5) Space optimization technology: By guiding the scientific and reasonable placement of tableware, the problem of wasted space and poor cleaning effect caused by users placing tableware based on experience can be avoided. At the same time, by adjusting the placement of tableware according to different parameters, the internal space of the dishwasher can be rationally utilized and the cleaning effect can be optimized.

[0071] In summary, the method provided by the embodiments of the present invention has the following advantages compared with the prior art: (1) Intelligent guidance: This invention uses image recognition technology. Users can take photos of used tableware on the dining table and upload them via a mobile app. The app identifies tableware with different parameters based on the images, such as size, depth, and degree of soiling. Then, it uses algorithms to calculate the space required for the tableware to be washed and guides the user to place it on the upper, middle, and lower shelves respectively. This intelligent guidance method not only simplifies the user's operation steps and improves operational efficiency, but also enables precise placement based on the different parameters of the tableware, achieving reasonable utilization of the dishwasher's internal space and optimal cleaning effect.

[0072] (2) Improved space utilization and cleaning effect: The image recognition and algorithm calculation technology of this invention can accurately determine the placement and method of tableware, thereby avoiding improper placement caused by insufficient human experience, and effectively improving the space utilization and cleaning effect of the dishwasher. At the same time, through the reasonable layout of tableware, the running time and energy consumption of the dishwasher can also be reduced, further improving the efficiency and energy saving effect.

[0073] (3) Enhanced User Experience: The image recognition and algorithm calculation technology of this invention eliminates the need for manual operation by the user. Users can simply take a photo and upload it via a mobile app to automatically place tableware and intelligently control the dishwasher, significantly improving user experience and satisfaction. Furthermore, due to the simplicity and convenience of this invention, even users with lower technical skills can easily master and use it, further expanding the user base and scope of application. In summary, compared to existing technologies, this invention offers advantages such as high intelligence, efficient space utilization, excellent cleaning effect, and enhanced user experience, making it a promising technical solution.
