It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] Please see Figures 1 to 4 , Figure 1 This is a flowchart illustrating an embodiment of a preservation control method for a refrigeration device according to this application; Figure 2 This is a schematic diagram of a sub-process in one embodiment of a preservation control method for a refrigeration device according to this application; Figure 3 This is another sub-process diagram of an embodiment of a preservation control method for a refrigeration device according to this application; Figure 4 This is another sub-process diagram of an embodiment of a preservation control method for a refrigeration device according to this application.

[0028] One embodiment of this application provides a method for controlling the preservation of food in a refrigeration device. The refrigeration device has a preservation space for placing food. The refrigeration device also includes a scanning device, a sensing component, and a preservation component. The scanning device is used to scan images of the food. The sensing component is used to sense environmental conditions within the preservation space. The preservation component is used to adjust the environmental conditions within the preservation space. The refrigeration device also includes a control device electrically connected to the scanning device, the sensing component, and the preservation component. The preservation control method of one embodiment of this application specifically includes the following steps:

[0029] S10: Control the scanning device to acquire images of food ingredients within the preservation space.

[0030] The preservation space can be the internal storage space of a sealed food storage container within a refrigeration unit. The scanning device can be built into the preservation space; or the preservation space can have a transparent viewing window through which the scanning device scans the preservation space.

[0031] The control device controls the scanning equipment to scan and acquire images of the food in the preservation space, which are then used for subsequent identification and analysis of the food types.

[0032] Furthermore, step S10 can be triggered when the preservation space is sensed to be opened, and then closed after being sensed to be open. When the preservation space is opened and then closed, it's possible that the user has placed food inside. The scanning device can be controlled to acquire images of the food inside the preservation space to adjust the preservation environment accordingly.

[0033] Specifically, the food storage compartment can be equipped with a magnetic switch. When the user opens the compartment to store food, the magnetic switch signal changes, adjusting the signal state from 1 (contact) to 0 (disconnect). When the food to be stored and preserved is placed in the compartment and the user closes it, the magnetic switch signal changes again, adjusting the signal state from 0 (disconnect) to 1 (contact). The control device detects the changes in the magnetic switch signal to determine whether the food storage compartment is open or closed.

[0034] The scanning device does not need to be closed when the food storage space is open, so it can scan and acquire food images as soon as the food storage space is closed, improving the speed of food image acquisition and reducing subsequent waiting time for users.

[0035] In other embodiments, step S10 can also be performed periodically to observe changes in the type and state of food within the preservation space.

[0036] S20: Confirm the type of food and the corresponding food preservation conditions based on the food images.

[0037] In some embodiments, the control device may have the function of recognizing food images and matching corresponding food preservation conditions. The refrigeration equipment can reduce communication requirements and automatically adjust the preservation environment when offline.

[0038] In some embodiments, to reduce the computational demands, hardware costs, and size of the refrigeration equipment's control device, the recognition and matching of food images can be uploaded to a cloud platform, and the recognition and matching results obtained from the cloud platform can be acquired. By uploading food images to the cloud platform, the recognition of food images, as well as the matching and filtering of food-related information such as food preservation conditions, can be performed through the cloud platform, reducing the computational demands of the refrigeration equipment's control device, thereby reducing hardware requirements and costs. The cloud platform can match and filter more large datasets, thereby improving the efficiency and accuracy of food image recognition, and the acquisition of food-related information such as food preservation conditions becomes more comprehensive and accurate. Specifically, the cloud platform can be an AI-powered intelligent IoT platform. The control device is a central processing unit.

[0039] Specifically, step S20, which confirms the type of food and the corresponding food preservation conditions based on the food image, includes the following steps:

[0040] S21: Upload the food images to the cloud platform and prompt the user to confirm the food images.

[0041] The control device uploads images of the food ingredients to a cloud platform and prompts the user to confirm the images.

[0042] In one application scenario, the refrigeration equipment may include a display screen for showing users images of food and other information, and for receiving user operation commands. This display screen can communicate with both a cloud platform and a control device to display content sent by both the cloud platform and the control device.

[0043] In another application scenario, the control device sends images of the food ingredients to a user terminal independent of the refrigeration equipment, such as a mobile phone, tablet, wearable device, or laptop. The user then sends commands to the refrigeration equipment through this user terminal. This user terminal is configured to establish a wireless connection with the control device, such as via Bluetooth or Wi-Fi, to send user commands. Specifically, corresponding applications or plugins can be installed on the terminal device, allowing the user to open and perform corresponding operations.

[0044] S22: In response to the user confirming the food image or the user not taking any action within the confirmation period, the cloud platform matches the food information based on the food image. The food information includes at least the type of food and the food preservation conditions.

[0045] In response to the user's confirmation of the food image, the cloud platform identifies the food image and matches food information based on the identification results. Food information includes at least the type of food and suitable or appropriate food preservation conditions, and may also include food storage time, food consumption suggestions, etc.

[0046] Specifically, users can confirm the food images by operating the display screen, by using voice commands, or by operating the food images on the user terminal.

[0047] If the user does not actively confirm or deny the food image within the confirmation period, it is determined that the user has accepted the food image as correct. The cloud platform then identifies the food image and matches the food information based on the identification result. Specifically, the confirmation period can be 3 seconds, 5 seconds, or other times.

[0048] After the user confirms the food image, the cloud platform then matches the food information. This avoids problems such as skewed or unclear food images obtained by scanning devices, prevents errors in food images from causing subsequent errors in food information acquisition, and improves the efficiency and accuracy of food image recognition.

[0049] In addition, in response to the user's rejection of the food image, the system returns to the step of controlling the scanning device to acquire an image of the food within the preservation space. Alternatively, the user can simultaneously input the type of food; the control device receives the user's input command and sends it to the cloud platform, where the cloud platform matches food information based on the type of food.

[0050] S23: Obtain the ingredient information identified by the cloud platform.

[0051] The control device acquires food information identified by the cloud platform, including food preservation conditions, food storage time, and food consumption recommendations.

[0052] In applications where refrigeration equipment includes a display screen, the display screen is used to show users images and information about the food, such as the type of food or item identified, the selected functional conditions, food preservation conditions, or food consumption suggestions.

[0053] In refrigeration equipment applications that include a voice transceiver module, the voice receiving module can be used to announce food information and receive voice control commands from the user. Specifically, this can include issuing voice commands to prompt the user about the types of food or items placed in the refrigeration space, the selected functional conditions, food preservation conditions, or food consumption suggestions, etc.

[0054] In application scenarios where the control device is wirelessly connected to an independent user terminal, the user terminal can send food images and food information to the user terminal, such as sending the identified food or item type, the selected functional conditions, food preservation conditions, or food consumption suggestions to the user.

[0055] S30: Control the sensing components to obtain the current environmental conditions of the preservation space.

[0056] After confirming the type of food and the corresponding preservation conditions through food images, the control device controls the sensing components to obtain the current environmental conditions of the preservation space, so as to provide adjustment direction for automatic adjustment of the preservation environment of the preservation space.

[0057] Current environmental conditions include current threshold values ​​for various environmental factors, such as temperature, moisture, gas composition and concentration, and microbial concentration. Gas composition and concentration include oxygen and its concentration, ethylene and its concentration, and odorous substances. Microbial concentration includes bacteria and their concentration, mold and its concentration, etc. The sensing component includes multiple sensing elements. Different sensing elements are used by users to detect different environmental factors, and corresponding sensing elements can be set according to actual product requirements.

[0058] In some embodiments, when the preservation space is opened, the current environmental conditions acquired by the sensing component are not the same as those of the closed preservation space, resulting in data errors. To avoid the sensing component transmitting erroneous signals, the preservation control method further includes:

[0059] In response to the opening of the preservation space, the control sensing components stop working.

[0060] When the control component receives a signal that the preservation space is open, indicating that the preservation space is not sealed, the control sensor component stops working to prevent it from detecting erroneous data. Stopping the control sensor component can involve ceasing to acquire signals from the sensor or temporarily disabling its detection function.

[0061] In response to the closure of the preservation space, the control sensor components are activated.

[0062] When the control component receives a signal that the preservation space is closed, the preservation space returns to a closed state, and the control sensor component starts working, allowing it to continue monitoring the environmental conditions within the preservation space. Starting the control sensor component includes either resuming signal acquisition from the sensor component or resuming its detection function.

[0063] S40: Analyze and compare the current environmental conditions and food preservation conditions to determine preservation adjustment decisions.

[0064] Food preservation is related to many environmental factors. By screening and analyzing the environmental factors related to the current environmental conditions in the food preservation conditions of a certain food and comparing them, it is possible to determine how the preservation components should adjust the current environmental conditions so that the current environmental conditions of the preservation space meet the food preservation conditions required by the food.

[0065] The current environmental conditions include the current thresholds of various environmental factors, the food preservation conditions include the target thresholds of various environmental factors, and the preservation components include multiple functional modules used to adjust the thresholds of various environmental factors.

[0066] In some embodiments, analyzing and comparing current environmental conditions and food preservation conditions to determine preservation adjustment decisions includes:

[0067] S41: Compare the threshold differences between the target threshold and the current threshold of each environmental factor related to the current environmental conditions in the food preservation conditions.

[0068] The system filters environmental factors related to the current environmental conditions from the food preservation conditions matched by big data from the cloud platform, and calculates the threshold difference between the target threshold and the current threshold for each environmental factor.

[0069] S42: Determine the regulation priority of each environmental factor based on the threshold difference.

[0070] In some embodiments, due to the integration of functional modules, some environmental factors cannot be adjusted simultaneously. Therefore, the adjustment priority of environmental factors can be determined based on the threshold difference.

[0071] There are several ways to determine the regulation priority of environmental factors, including but not limited to the following two:

[0072] The first method involves a direct correlation between the adjustment priority of environmental factors and their corresponding threshold differences. The adjustment priority of environmental factors is determined directly by the absolute value of the threshold difference. This approach allows for the direct adjustment of the environmental factors that deviate most from suitable food preservation conditions, and then the subsequent adjustment of other environmental factors, ultimately achieving a suitable preservation effect for the food within the preservation space.

[0073] The second method multiplies the threshold difference of each environmental factor by its adjustment weight value to obtain a weighted threshold. The adjustment priority of an environmental factor is positively correlated with its corresponding weighted threshold. The importance of different environmental factors varies for different foods, therefore the adjustment weight values ​​of different environmental factors are related to the type of food. This method can balance the threshold difference of environmental factors with their importance, allowing for the adjustment of the most critical environmental factors and subsequent adjustments of other environmental factors, thus achieving a suitable preservation effect for the food within the preservation space.

[0074] S43: The corresponding functional modules are controlled to adjust the environmental factors in descending order of their adjustment priority.

[0075] The preservation decision is determined as follows: Environmental factors are adjusted in descending order of priority, and the corresponding functional modules are controlled accordingly. This preservation decision ensures that food achieves a suitable preservation effect.

[0076] S50: Controls the preservation components to adjust according to the preservation adjustment decision until the current environmental conditions of the preservation space meet the food preservation requirements.

[0077] In some embodiments, the preservation component includes an annular box and a ventilation channel. The ventilation channel is connected to the air supply path of the preservation space. Multiple functional modules are arranged circumferentially within the annular box, each providing a different preservation function. The annular box can rotate around the ventilation channel, allowing air from the air supply path to pass through the ventilation channel and two corresponding functional modules before entering the preservation space. At least one functional module in the annular box may be used solely for ventilation, without other preservation functions, to accommodate situations where the preservation space only requires air supply from a refrigeration unit. Further, multiple annular boxes can be arranged radially, such as two, three, or more. Different annular boxes are coaxially arranged and can rotate relative to each other to provide more preservation functions, and different combinations of functional modules can further improve preservation regulation efficiency.

[0078] The functional modules can include desiccants, activated carbon, temperature control mechanisms, moisture supply mechanisms, vitamin C inducers, palladium mesh, UV sterilization, or lysozyme. Desiccants adsorb moisture to meet the requirements of foods needing dry storage. Activated carbon removes odors and harmful substances. The temperature control mechanism adjusts the temperature of the air supplied to the food storage container according to the storage needs of the food; for example, the temperature can be increased for foods requiring thawing, or decreased for foods requiring freezing. The moisture supply mechanism provides moisture to foods requiring higher humidity. Vitamin C inducers release vitamin C to neutralize ethylene, producing moisture and carbon dioxide, thus providing nutrients to fruits and vegetables. Lysozyme kills hundreds of bacteria, including E. coli and Staphylococcus, preventing bacterial contamination of food. The palladium mesh catalyzes the reaction of ethylene and oxygen, neutralizing ethylene, reducing oxygen concentration, and decreasing aerobic respiration in fruits and vegetables. UV sterilization uses wavelengths to destroy the genetic material of bacteria, viruses, parasites, and other pathogens, rendering them unable to replicate or reproduce, thereby achieving disinfection. In some embodiments of this application, the density of different functional modules is the same to ensure that the air volume delivered to the preservation space is the same after any combination of functional modules.

[0079] The adjustment work of the preservation components based on the preservation adjustment decision control includes:

[0080] S51: Control the rotation of the ring box so that the functional module corresponding to the highest priority environmental factor rotates to connect with the ventilation channel, and control the refrigeration module of the refrigeration equipment to send air to the ventilation channel.

[0081] The functional modules are set up in the environment box, which can reduce the space occupied by the preservation components and reduce costs.

[0082] In some embodiments, the functional modules of the preservation space are independent of each other or partially independent. When the preservation components are adjusted according to the preservation adjustment decision, the independently set functional modules can be adjusted synchronously with the priority adjustment functional modules, thereby further improving the adjustment efficiency.

[0083] S52: In response to the current threshold of the corresponding environmental factor in the preservation space reaching the target threshold, control the ring box to rotate so that the functional module corresponding to the next priority environmental factor rotates to connect with the ventilation channel.

[0084] The sensing components monitor the environmental conditions within the preservation space in real time and determine whether the currently adjusted environmental factor has reached the target threshold. In response to the current threshold of the corresponding environmental factor within the preservation space reaching the target threshold, the ring box is controlled to rotate so that the functional module corresponding to the next priority environmental factor rotates to connect with the ventilation channel.

[0085] S53: In response to the current threshold of various environmental factors in the preservation space reaching the target threshold, control the ring box to rotate to connect with the non-functional module and the ventilation channel.

[0086] Multiple functional modules can be placed in the ring box to enable the adjustment of environmental factors in the preservation space. Furthermore, the combination of functional modules can be driven to achieve targeted environmental adjustment of the preservation space according to the different needs of different foods for the preservation environment, so as to achieve a suitable food storage environment and extend the shelf life of the food.

[0087] The preservation control method of this application acquires food images through scanning equipment, obtains environmental conditions through sensing components, and combines big data intelligent recognition with traditional preservation methods to control multiple functional modules of the preservation components to achieve the desired food preservation effect. This application can automatically and precisely adjust the preservation conditions according to the different needs of different foods, achieving a suitable food storage environment, extending the shelf life of the food, preserving it better, improving its quality and taste, reducing the loss of nutrients, and improving the overall quality of the food, while also reducing waste caused by improper storage or preservation. Furthermore, by combining the preservation control method of this application with IoT big data, it can more intelligently display product characteristics, provide suitable storage and preservation knowledge for different foods, and maximize the application of the combination of network technology and traditional methods in food preservation.

[0088] Please see Figure 5 , Figure 5 This is an interactive framework diagram of a preservation control method for a refrigeration device according to this application. The preservation control method of this application will be described below with reference to a specific embodiment:

[0089] The user opens the preservation compartment and places strawberries inside. When the preservation compartment is opened, the scanning device continues to operate, but the sensing components temporarily disable, pausing the output of detection signals. After the strawberries are placed in the preservation compartment, the built-in scanning device identifies and extracts the strawberry image, and transmits the extracted strawberry image to the intelligent platform and the display screen. The display screen shows the strawberry image and prompts the user to confirm the identified strawberry image.

[0090] Once the user confirms the strawberry image is correct, or if the user does not confirm the image within 5 seconds, the intelligent platform matches the strawberry image with relevant information. Through big data filtering and management, the platform displays relevant strawberry knowledge on the screen, listing suitable strawberry preservation conditions, maximum shelf life, etc. For example, the screen displays a strawberry information summary, including: strawberry characteristics, growing environment, main functions and effects, and suitable preservation conditions. The preservation conditions are listed, including: 1. Suitable preservation temperature: 0-4℃; 2. Optimal preservation humidity: 80-90%; 3. Optimal preservation environment: anaerobic environment (oxygen concentration less than 30%); 4. Aseptic storage, etc.

[0091] The data is sent back to the central processing unit for analysis, calculation, and processing. The preservation components in the preservation space begin to detect the environmental conditions of the strawberry's preservation space and output the detected current environmental conditions to the central processing unit. For example, the detected environmental conditions around the strawberry in the preservation space are: 1. Preservation chamber temperature: 6℃; 2. Preservation chamber humidity: 30%; 3. Preservation chamber oxygen concentration: 60%; 4. Sterile, etc.

[0092] At this point, the central processing unit (CPU) processes the strawberry preservation conditions detected by the actual strawberry environment, matching and filtering them with IoT big data. It then compares the target threshold of the environmental factors in the strawberry preservation conditions with the current threshold of the corresponding environmental factors in the current environment, outputting the corresponding threshold difference. Based on this threshold difference, the CPU adjusts the preservation components sequentially from high to low.

[0093] The preservation component executes relevant processing instructions, controls the rotation of the ring box, retrieves the corresponding functional module and connects with the ventilation channel, and delivers gas into the preservation space through the air supply path. The gas passes through the functional module to adjust the environmental factors in the preservation space where the strawberries are located until the environmental factors in the preservation space meet the suitable conditions for strawberry preservation.

[0094] Please see Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of an embodiment of the refrigeration equipment of this application; Figure 7 This is a partial structural schematic diagram of an embodiment of the refrigeration equipment of this application.

[0095] Another embodiment of this application provides a refrigeration device 100. The refrigeration device 100 has a preservation space 101 for placing food. The refrigeration device 100 also includes a scanning device (not shown), a sensing component (not shown), and a preservation component 110. The scanning device is used to scan images of the food. The sensing component is used to sense environmental conditions within the preservation space 101. The preservation component 110 is used to adjust the environmental conditions within the preservation space 101. The refrigeration device 100 also has a control device (not shown), which is electrically connected to the scanning device, the sensing component, and the preservation component 110, for implementing the preservation control method in any of the above embodiments.

[0096] Furthermore, the preservation component 110 includes an annular box 120 and a ventilation channel 122. The ventilation channel 122 is connected to the air supply path of the preservation space 101. Multiple functional modules 121 are arranged circumferentially within the annular box 120. Different functional modules 121 provide different preservation functions. The annular box 120 can rotate around the ventilation channel 122, so that the air supplied by the air supply path enters the preservation space 101 after passing through the ventilation channel 122 and the corresponding two functional modules 121.

[0097] Furthermore, multiple annular boxes 120 may be arranged radially, such as two, three, or more. Different annular boxes 120 are coaxially arranged and can rotate relative to each other. At least one functional module 121 in each annular box 120 may be used only for ventilation, without other preservation functions.

[0098] The preservation space 101 can be the space inside a food storage container or a food storage drawer of the refrigeration equipment 100. The preservation component 110 is disposed on its cover 130.

[0099] The refrigeration equipment 100 of this application acquires images of food through scanning equipment, obtains environmental conditions through sensing components, and combines big data intelligent recognition with traditional preservation methods to control multiple functional modules 121 of the preservation component 110 to achieve the desired food preservation effect. The refrigeration equipment 100 can automatically and precisely adjust the preservation conditions according to the different needs of different foods, achieving a suitable food storage environment, extending the shelf life of the food, preserving it better, improving its quality and taste, reducing the loss of nutrients, and improving the overall quality of the food, while also reducing waste caused by improper storage or preservation. Furthermore, by integrating IoT big data, the refrigeration equipment 100 can more intelligently display product characteristics and provide suitable storage and preservation tips for different foods, maximizing the application of the combination of network technology and traditional methods in food preservation.

[0106] The terms "first," "second," and "third" in this application are for descriptive purposes only and should not be construed as indicating the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of those features. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indications will change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. A process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0107] It should be noted that the terms "horizontal" and "vertical" do not imply that the components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. Similarly, the terms "parallel" and "perpendicular" do not imply that the components are absolutely parallel or perpendicular, but rather that they can have a certain angular deviation. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted. Furthermore, the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0108] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
