Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and in particular to a refrigeration device, control method and food storage system. Background Technology

[0002] Since most foods do not spoil easily at low temperatures and can be stored for a longer period of time, refrigerators have become a household refrigeration device used by most families to preserve food, bringing convenience to people's daily lives.

[0003] With the development of the concept of smart devices, refrigeration equipment is gradually moving towards intelligence and energy conservation. However, the temperature control function of traditional refrigerators usually relies on manual adjustment or preset modes. The temperature control strategy of these refrigerators is relatively simple, and the accuracy of temperature and humidity control is not high, resulting in poor food storage. Summary of the Invention

[0004] This application provides a refrigeration device, control method, and food storage system to solve the problem that traditional refrigerators have relatively simple temperature control strategies and low temperature and humidity control accuracy, resulting in poor food storage effects.

[0005] In a first aspect, a refrigeration device is provided, comprising a housing, a refrigeration system, and a control device. The housing has multiple storage compartments for containing food, and the refrigeration system is used to regulate the temperature and humidity of each of the multiple storage compartments. The control device is configured to perform the following steps:

[0006] After detecting an increase in stored food in the storage area, the storage conditions of the stored food are predicted based on the type of food stored.

[0007] Based on the storage conditions of the food stored in each storage area, determine the amount of refrigeration that needs to be increased or decreased in each storage area and the refrigeration priority of each storage area;

[0008] Based on the required increase or decrease in cooling capacity for each storage area and the cooling priority of each storage area, the temperature and humidity of each storage area are controlled in a graded and zoned manner through the refrigeration system.

[0009] Since different foods have different temperature and humidity storage requirements, the above solution sets up multiple independent storage zones in the refrigeration equipment. After detecting an increase in the amount of food stored in a storage zone, it can predict the storage conditions of the food based on the type of food. Then, based on the storage conditions of the food stored in each storage zone, it determines the amount of refrigeration that needs to be increased or decreased in each storage zone and the refrigeration priority of each storage zone. The temperature and humidity of each storage zone are controlled in a graded and zoned manner through the refrigeration system, which improves the accuracy of temperature and humidity control of the refrigeration equipment. This ensures that the temperature and humidity in different storage zones meet the storage requirements of the food being stored, thereby improving the food storage effect.

[0010] In some embodiments, a refrigeration device is provided. The refrigeration system of the refrigeration device includes a compressor and a cold energy delivery device for controlling the temperature and humidity of each storage area. The control device, based on the required increase or decrease in refrigeration capacity for each storage area and the refrigeration priority of each storage area, performs graded and zoned control of the temperature and humidity of each storage area through the refrigeration system. It is configured to perform the following steps: determining the target frequency required by the compressor based on the required increase or decrease in refrigeration capacity for each storage area; controlling the compressor to operate according to the target frequency; and sequentially delivering the corresponding refrigeration capacity of each storage area to each storage area through the cold energy delivery device according to the refrigeration priority of each storage area, thereby realizing graded and zoned control of the temperature and humidity of each storage area.

[0011] In the above scheme, the compressor's operating frequency is adaptively adjusted based on the required increase or decrease in cooling capacity in each storage area, and the cooling capacity delivery control of the cooling capacity delivery device is dynamically adjusted. This allows for dynamic adjustment of the temperature and humidity in each storage area according to food storage needs and the specific storage environment, achieving precise and energy-saving temperature control management.

[0012] In some embodiments, a refrigeration device is provided, an environmental detection device in each storage area, and a control device is further configured to perform the step of: detecting environmental information of each storage area through the environmental detection device in each storage area, the environmental information including temperature and humidity information and food quantity in the storage area;

[0013] The control equipment determines the required increase or decrease in cooling capacity and the cooling priority of each storage area based on the storage conditions of the food stored in each storage area. It is configured to execute the following steps: determine the required increase or decrease in cooling capacity for each storage area based on the quantity of food, temperature and humidity information, and storage conditions of the food stored in each storage area; and determine the cooling priority of each storage area based on the type of each storage area and the type of food stored in each storage area.

[0014] In the above scheme, the required increase or decrease in refrigeration capacity for each storage area is determined based on the quantity of food, temperature and humidity information, and storage conditions of the stored food, thus improving the accuracy of refrigeration capacity. Based on the type of each storage area and the type of food stored in each storage area, the refrigeration priority of each storage area is determined, taking into account the impact of the nature of different storage areas and different food types on the urgency of refrigeration demand, thus improving the accuracy of refrigeration priority for storage areas.

[0015] In some embodiments, a refrigeration device is provided, wherein a control device determines the refrigeration priority of each storage zone based on the type of each storage zone and the type of food stored in each storage zone, and is configured to perform the step of: determining the refrigeration priority of each storage zone based on the type of each storage zone, the type of food stored in each storage zone, and the freshness before storage. This solution not only considers the impact of the type of each storage zone and the type of food on the urgency of refrigeration demand, but also considers the impact of the freshness of the food in each storage zone on the urgency of refrigeration demand, enabling the determination of the refrigeration priority of storage zones from multiple perspectives and improving the accuracy of refrigeration priority.

[0016] In some embodiments, a refrigeration device is provided, with a label scanning device installed on the cabinet or each storage area. A control device predicts the storage conditions of the stored food based on its type and is configured to perform the following steps: acquiring input information of the stored food in each storage area, the input information including at least the type of food, obtained by controlling the label scanning device to scan the information labels of the stored food; and predicting the storage conditions of the food based on its type and the environmental information of the storage area. This solution considers the impact of the environmental information of the storage area on the food storage effect when predicting the storage conditions, which can improve the accuracy of the storage conditions and thus improve the precision of subsequent temperature and humidity control.

[0017] In some embodiments, a refrigeration device is provided. The input information further includes recommended storage conditions, production date, and shelf life of the stored food. A control device predicts the storage conditions of the stored food based on the food type and environmental information of the storage area in each storage zone. This is configured to perform the following steps: determining the pre-storage freshness of the stored food before it is stored in the storage zone based on its food type, production date, and shelf life; and predicting the storage conditions of the stored food based on its food type, pre-storage freshness, recommended storage conditions, and environmental information of the storage zone. This solution considers the impact of food type, pre-storage freshness, and environmental information on the food storage conditions when determining them, thus improving the accuracy of storage condition prediction.

[0018] In some embodiments, a refrigeration device is provided. After predicting the storage conditions of the stored food, the control device is further configured to perform the following steps: recording the storage conditions and storage time of the stored food into the food's input information, and monitoring the temperature and humidity changes in each storage area in real time; predicting the freshness of the stored food based on the storage conditions, pre-storage freshness, and temperature and humidity changes in the storage area where the food is located, to obtain the real-time freshness of the stored food; and providing a food freshness reminder based on the real-time freshness of the stored food. In this solution, by predicting the freshness of the stored food, the real-time freshness of the stored food can be obtained quickly and accurately, enabling timely reminders to users about the freshness status of the stored food, ensuring that users can use the corresponding stored food in a timely manner, and improving the user experience.

[0019] In some embodiments, a refrigeration device is provided, with a display panel on the cabinet. The control device provides food freshness reminders based on the real-time freshness of the stored food, configured to perform the following steps: generating freshness reminder information for the stored food based on its real-time freshness, storage time, and the storage area where the food is located; and controlling the display panel to display the freshness reminder information. In this solution, the freshness reminder information can inform the user of the food's freshness status and allow them to retrieve the food from its storage location, ensuring that the user can access the stored food promptly and improving the user experience.

[0020] In some embodiments, a refrigeration device is provided, wherein the control device is further configured to: upon receiving an information input instruction, display a food information interface on a display panel on the control unit, the food information interface including a food addition control; responding to a trigger operation on the food addition control, control the display panel to display the information input interface; and, upon obtaining food information input based on the food information interface, determine that an increase in stored food has been detected in the storage area, and generate and store input information for the stored food based on the food information, the input information including the food type of the stored food. In this solution, by interacting with the user through the display panel, the control device can quickly determine the increase in stored food based on the user interaction process, and quickly and accurately obtain information such as the food type of the stored food, thereby improving the user experience.

[0021] Secondly, a method for controlling a refrigeration device is provided, the method comprising the following steps:

[0022] After detecting an increase in the amount of food stored in the storage area of ​​the refrigeration equipment, the storage conditions of the stored food are predicted based on the type of food stored.

[0023] Based on the storage conditions of the food stored in multiple storage zones of the refrigeration equipment, determine the amount of refrigeration that needs to be increased or decreased in each storage zone and the refrigeration priority of each storage zone;

[0024] Based on the required increase or decrease in cooling capacity for each storage area and the cooling priority of each storage area, the temperature and humidity of each storage area are controlled in a graded and zoned manner through the cooling system of the refrigeration equipment.

[0025] Thirdly, a food storage system is provided, including the aforementioned refrigeration equipment.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0052] It should be understood that the sequence number of each step in the following embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0053] To illustrate the technical solution of the present invention, specific embodiments are described below.

[0054] It's important to understand that traditional refrigeration equipment (such as refrigerators) typically relies on manual adjustment or preset temperature control modes for temperature control. For example, users need to manually adjust the temperature of one or more temperature zones in the refrigerator; or, some refrigerators have remote control functions, allowing users to remotely adjust the temperature or activate preset modes, such as basic energy-saving mode or quick-freeze mode. However, in actual refrigerator use, it's common to store a variety of foods, each with different requirements. Traditional refrigerators have relatively simple temperature control strategies and low precision in temperature and humidity control, failing to meet the precise storage needs of diverse foods. This can easily lead to over-regulation or insufficient temperature and humidity, resulting in poor food freshness and ineffective food storage. Furthermore, excessive temperature and humidity control can also cause excessive energy consumption, failing to meet energy-saving requirements and leading to a poor user experience. Food storage effectiveness refers to maintaining the texture, color, taste, and nutritional value of stored food within a certain period, achieving long-term freshness.

[0055] To improve the temperature and humidity control accuracy of refrigeration equipment, thereby enhancing food storage effectiveness and reducing energy consumption, this application provides a refrigeration device, a food storage system, and a control method for the refrigeration device. This method, upon detecting an increase in stored food in a storage area of ​​the refrigeration equipment, predicts the storage conditions of the stored food based on its type. Then, based on the storage conditions of the food in multiple storage areas, it determines the required increase or decrease in refrigeration capacity for each storage area and the refrigeration priority for each area. Furthermore, based on the required increase or decrease in refrigeration capacity and the refrigeration priority for each storage area, the refrigeration system performs graded and zoned control of the temperature and humidity in each storage area. This solution improves the accuracy of temperature and humidity control in the refrigeration equipment, ensuring that the temperature and humidity in different storage areas meet the storage requirements of the food, improving food storage effectiveness, reducing over-regulation of temperature and humidity, lowering energy consumption of the refrigeration equipment, and enhancing the user experience.

[0056] To facilitate a further understanding of the technical solutions in some embodiments of this application, the technical solutions of refrigeration equipment, food storage systems, and control methods for refrigeration equipment, as well as how these technical solutions solve the aforementioned technical problems, are described in detail below with reference to specific embodiments and accompanying drawings. The embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application.

[0057] The control method for refrigeration equipment provided in this embodiment of the invention can be applied to, for example... Figure 1 The food storage system shown includes refrigeration equipment. Figure 2As shown, the refrigeration equipment includes a housing, a refrigeration system, and a control device. The housing has multiple storage compartments for holding food, and the refrigeration system regulates the temperature and humidity of each compartment. The control device is connected to the refrigeration system via cables and controls the system.

[0058] The control device is configured to perform the following steps: after detecting an increase in stored food in the storage area, predict the storage conditions of the stored food based on the type of food; determine the required increase or decrease in refrigeration capacity and the refrigeration priority of each storage area based on the storage conditions of the stored food in each storage area; and perform graded and zoned control of the temperature and humidity of each storage area through the refrigeration system based on the required increase or decrease in refrigeration capacity and the refrigeration priority of each storage area.

[0059] In this embodiment, by independently setting up multiple storage zones within the refrigeration equipment, and upon detecting an increase in the amount of food stored in a zone, the system can determine the required increase or decrease in refrigeration capacity and the refrigeration priority for each zone based on the storage conditions of the food. Furthermore, the refrigeration system implements graded and zoned control of temperature and humidity in each storage zone, improving the accuracy of temperature and humidity control within the refrigeration equipment. This ensures that the temperature and humidity in different storage zones meet the storage requirements of the food being stored, thereby improving the food storage effect. In addition, by implementing graded and zoned control of temperature and humidity in each storage zone, the refrigeration system improves the accuracy of temperature and humidity control within the refrigeration equipment, ensuring that the temperature and humidity in different storage zones meet the storage requirements of the food being stored, improving the food storage effect, reducing over-regulation of temperature and humidity, lowering the energy consumption of the refrigeration equipment, and enhancing the user experience.

[0060] The refrigeration device provided in this application can have various implementation forms. For example, the refrigeration device can be a refrigerator, such as... Figure 3 As shown. The refrigerator can be a household refrigerator, a commercial refrigerator, or a vehicle refrigerator. In other embodiments, the refrigeration device can also be a freezer.

[0061] In some embodiments, the food storage system includes a refrigeration unit and a user terminal. The user sends relevant instructions (such as instructions to add food, input information, or control the temperature of the storage area) to the control unit of the refrigeration unit via the user terminal. Upon receiving the instructions, the control unit determines that an increase in stored food has been detected in the storage area of ​​the refrigeration unit and then executes subsequent storage condition prediction and temperature and humidity adjustment processes. Remote control of the refrigeration unit via the user terminal improves both the food storage effect and the user experience.

[0062] In some embodiments, such as Figure 4 As shown, a control method for a refrigeration device is provided, which is applied to... Figure 2Taking the control device of a refrigeration equipment as an example, the control device is configured to perform the following steps:

[0063] S10: After detecting an increase in the amount of food stored in the storage area of ​​the refrigeration equipment, the storage conditions of the food are predicted based on the type of food stored.

[0064] In this embodiment, the refrigeration equipment includes a housing, a refrigeration system, and a control device. The housing has multiple storage areas for holding food. The housing of the refrigeration equipment includes a freezer compartment and a refrigerator compartment. The freezer compartment includes multiple storage areas, and the refrigerator compartment also includes multiple storage areas. Figure 5 As shown, the multiple storage areas of the cabinet include storage area 1, storage area 2, storage area 3, and storage area 4; in other embodiments, the multiple storage areas of the refrigeration equipment can also be arranged in other ways, which will not be described in detail here. The refrigeration system is used to regulate the temperature and humidity of each of the multiple storage areas.

[0065] During the operation of the refrigeration equipment, the control device in the refrigeration equipment needs to detect changes in the stored food in multiple storage areas of the cabinet, in order to detect whether the amount of stored food in the storage areas of the cabinet has increased.

[0066] For example, image acquisition devices can be installed in the storage area to capture images of stored food. The control device can then identify and compare the images captured by the image acquisition devices to determine in real time whether the current stored food images in the storage area have increased compared to historical stored food images.

[0067] It's important to understand that different foods have different storage requirements, meaning they require different storage conditions. For example, the storage requirement for fruits and vegetables is freshness preservation. To prevent excessively low temperatures from causing water crystallization, cell rupture, and spoilage, the storage temperature for fruits and vegetables needs to be higher than that for processed foods (such as canned goods and condiments). To ensure the optimal storage effect (i.e., freshness and shelf life) for foods in different storage zones, when an increase in the amount of food stored in a storage zone of the refrigeration equipment is detected, the control device needs to determine the type of food stored in that zone and predict the appropriate storage conditions based on that type.

[0068] This system can collect storage data for multiple food types, including the storage effects (preservation effect and preservation time) of each type of food under different storage conditions. A neural network is trained based on this data to obtain a food storage prediction model for predicting storage conditions for different food types. Upon detecting an increase in stored food in the storage area of ​​the refrigeration unit, the control device determines the type of food in the storage area and inputs this type into the food storage prediction model to predict storage conditions that meet the requirements of that food. These storage conditions include at least one of storage temperature, storage humidity, and storage time.

[0069] The food types for storage are categorized based on commonly used food items in daily life. These food types can be further classified hierarchically, ultimately down to specific subcategories by food name. For example, food types can be categorized into multiple levels. Primary food types include staple foods, proteins, fruits and vegetables, dairy products, and other categories (such as condiments). Staple foods mainly consist of grains and tubers. Secondary food types under staple foods include grains, tubers, and processed starches. Tertiary food types under grains include various cereals such as rice, millet, corn, and wheat; tubers include various tubers such as sweet potatoes and purple sweet potatoes; and processed starches include various pasta dishes, porridge, and bread. Similarly, secondary food types under proteins include meat, poultry, fish, beans, and nuts. These can be further subdivided into tertiary food types. Secondary food types under fruits and vegetables include various vegetables and fruits, and these can also be subdivided into tertiary food types. The secondary food categories of dairy products include milk, yogurt, milk powder, and cheese, which are further subdivided into tertiary food categories. Different food types have different storage requirements, and even within the same type, different specific foods have varying storage requirements. By subdividing food types according to actual food needs, we can determine and predict the storage conditions for specific foods with higher accuracy, providing a precise data foundation for subsequent accurate control of temperature and humidity in each storage area.

[0070] S20: Based on the storage conditions of the food stored in multiple storage areas of the refrigeration equipment, determine the amount of refrigeration that needs to be increased or decreased in each storage area and the refrigeration priority of each storage area.

[0071] It's important to understand that different foods require different storage conditions, including varying temperatures and humidity levels. The temperature and humidity information within each storage zone also differs, resulting in varying requirements for increased or decreased refrigeration capacity. Furthermore, different types of food require different storage conditions and have different refrigeration priorities within their respective storage zones.

[0072] After predicting the storage conditions of the food, the control device needs to determine the amount of cooling capacity that needs to be increased or decreased in each storage zone based on the storage conditions of the food in multiple storage zones of the refrigeration equipment, as well as the temperature and humidity information in each storage zone, and determine the cooling priority of each storage zone.

[0073] For example, the required cooling capacity for each storage area under different temperature increments can be pre-calibrated to obtain cooling capacity calibration data. After determining the temperature difference between the current temperature information of the storage area and the storage temperature, the temperature difference is matched with the temperature increment in the cooling capacity calibration data. The required cooling capacity for the matched temperature increment is used as the cooling capacity that needs to be increased or decreased for that storage area.

[0074] The cooling priority of each storage area can be determined based on the type of food. For example, the cabinet is divided into separate refrigerator and freezer compartments. The refrigerator compartment includes multiple storage areas, and the freezer compartment also includes multiple storage areas. The refrigerator compartment stores fruits and vegetables, while the freezer compartment stores frozen foods (such as ice cubes and ice cream). Frozen foods require lower temperature and humidity conditions for storage, so the cooling priority of the storage area storing frozen foods is higher than that of the storage area storing fruits and vegetables.

[0075] In other embodiments, the cooling priority of each storage area can also be determined by the increase in food. For example, if it is detected that some storage areas have added stored food and some storage areas have not added stored food, then the cooling priority of the storage area with added stored food is higher than the cooling priority of the storage area without added stored food.

[0076] S30: Based on the required increase or decrease in cooling capacity for each storage area and the cooling priority of each storage area, the temperature and humidity of each storage area are controlled in a graded and zoned manner through the refrigeration system.

[0077] After determining the required increase or decrease in cooling capacity for each storage area and the cooling priority of each storage area, the control device uses the refrigeration system to classify and zone the temperature and humidity of each storage area according to the required increase or decrease in cooling capacity and the cooling priority of each storage area.

[0078] The system delivers cooling capacity to each storage area via a refrigeration system, ensuring that the temperature and humidity in each area meet the storage requirements for food. Different storage areas are controlled by delivering varying amounts of cooling capacity. When delivering cooling capacity to each storage area, the order in which the cooling capacity is delivered is determined by the cooling priority of each area; higher priority areas are delivered earlier in the order.

[0079] In this embodiment, upon detecting an increase in stored food in the storage areas of the refrigeration equipment, the storage conditions of the stored food can be predicted based on its type. Then, based on the storage conditions of the food in multiple storage areas, the required increase or decrease in refrigeration capacity and the refrigeration priority of each storage area are determined. Subsequently, based on the required increase or decrease in refrigeration capacity and the refrigeration priority of each storage area, the temperature and humidity of each storage area are controlled in a graded and zoned manner through the refrigeration system. This solution can improve the accuracy of temperature and humidity control in the refrigeration equipment, ensuring that the temperature and humidity in different storage areas meet the storage requirements of the stored food, improving the food storage effect, reducing excessive temperature and humidity control, lowering the energy consumption of the refrigeration equipment, and improving the user experience.

[0080] In some embodiments, label scanners (such as barcode scanners) are installed on the container (or each storage area), such as... Figure 3 As shown, a label scanning device is installed on the outer wall of the container (such as the container door), and a label scanning device can also be installed on the inner side of the container, such as... Figure 5 As shown; in other embodiments, label scanning devices can also be installed at corresponding locations in each storage area (such as at the entrance of the storage area). These label scanning devices are used to detect and scan the information labels of stored food, and to identify the food information associated with the information label. For example, Figure 6 As shown, the control device detects whether the amount of food stored in the storage area of ​​the refrigeration equipment has increased, and is configured to perform the following steps:

[0081] SA01: Detects and scans the information tags of stored food using a label scanner, and determines the entry information of stored food based on the food information associated with the information tags.

[0082] When users store food using refrigeration equipment, they can place the information labels of the stored food near the cabinet or the label scanning devices in each storage area. The label scanning devices will then scan and identify the information labels to obtain the food information associated with them. The information labels can be barcode labels, shopping receipts including product barcodes or QR codes. The label scanning devices can be barcode scanners, QR code scanners, etc.

[0083] When the control device detects an information tag on the stored food via the tag scanning device, it controls the tag scanning device to scan the information tag and determine the recorded information of the stored food in the storage area based on the food information associated with the information tag. The recorded information includes at least the food type of the stored food. In other embodiments, this recorded information includes recommended storage conditions, production date, shelf life, storage time, purchase time, and transportation details. The food type and related information of the stored food can be quickly determined through the recorded information.

[0084] SA02: Match the entered information of stored food with the entered information already stored in the refrigeration equipment. If no matching information is found in the stored information, it is determined that an increase in stored food has been detected in the storage area of ​​the cabinet.

[0085] The control device matches the entered information of the stored food with the entered information of the stored food already stored in the refrigeration equipment to determine whether an increase in stored food has been detected in the storage area of ​​the cabinet. If no stored information is found, it is determined that an increase in stored food has been detected in the storage area of ​​the cabinet. If stored information is found, it means that the entered information for the stored food has been stored, and the stored food is already stored in the refrigeration equipment; therefore, it is determined that no increase in stored food has been detected in the storage area of ​​the cabinet.

[0086] In this embodiment, a label scanner detects and scans the information label (which can be a barcode) of the stored food, and determines the recorded information of the stored food based on the food information associated with the information label. The recorded information of the stored food is then matched with the recorded information already stored in the refrigeration equipment. If no matching information is found in the stored information, it is determined that an increase in the stored food has been detected in the storage area of ​​the cabinet. By scanning the food information label with a label scanner, the control device can quickly determine the addition of stored food and quickly and accurately obtain information such as the type of stored food, reducing the amount of data processing and energy consumption.

[0087] In some embodiments, the enclosure is also provided with a display panel. For example... Figure 7 As shown, in step S10, the control device detects whether the amount of stored food in the storage area of ​​the refrigeration equipment has increased, and is also configured to perform the following steps:

[0088] SB01: When an information entry command is received, the display panel on the control box displays the food information interface, which includes controls for adding food items.

[0089] A display panel is installed on the outer wall of the cabinet (such as the door), displaying a food information interface for users to input information about the stored food. When the stored food does not have an information label, or the control device cannot scan the information label using the label scanner (e.g., the label scanner is not installed or is malfunctioning), the user can send an information input command to the control device. Upon receiving the command, the control device displays the food information interface on the display panel, which includes controls for adding food items. The user can then operate the controls on the food information interface so that the control device can interact with the user based on their actions, facilitating the input of stored food information via the display panel. The food information interface can display pre-categorized food types; clicking on a food type allows for quick identification and input of relevant information. See above for the classification methods of different food types.

[0090] The information entry command can be input through prompts on the display panel, triggered by voice, or sent by the user via a user terminal. In other embodiments, upon receiving the information entry command, the control device can display a food information interface on the user terminal and receive user operation information on the food information interface on the user terminal to perform operations such as entering information about stored food.

[0091] SB02: In response to the triggering operation of adding a new food control, control the display panel to show the information entry interface.

[0092] The food information interface includes a food addition control. When a user needs to store food, they can trigger the food addition control on the food information interface. The control device responds to the user's triggering operation by displaying the information entry interface on the control panel. The user can enter relevant food information for storing the food on the information entry interface to obtain the information for adding the food to be stored.

[0093] SB03: Upon obtaining food information input from the food information interface, determine that an increase in stored food has been detected in the storage area, and generate and store the input information of the stored food based on the food information.

[0094] Specifically, upon receiving food information input by the user through the food information interface, the control device determines that an increase in stored food has been detected in the storage area. Based on the user-inputted food information, it generates and stores the entry information for the newly stored food and displays this information on the food information interface. The entry information includes the type of stored food to facilitate subsequent storage condition prediction.

[0095] The food information interface may also include information modification controls; the food information interface may also include information deletion controls. The food information interface displays a list of stored food entries, including multiple stored foods and basic information (such as food type, storage time, etc.) stored in the refrigeration equipment. For each stored food item in the entry information list on the food information interface, corresponding positions are provided with information modification controls and information deletion controls.

[0096] Users can modify food information by triggering the information modification controls on the food information interface. In response, the control device displays the information entry interface on the control panel, allowing users to modify the corresponding stored food information. When the control device receives food information input from the food information interface, it updates the stored food information accordingly. When a user needs to retrieve stored food, they can delete it by triggering the information deletion controls on the food information interface. The control device then deletes the corresponding stored food information, enabling subsequent temperature and humidity control of each refrigerated area and providing freshness reminders based on the actual stored food information.

[0097] In this embodiment, when the control device receives an information input command, it controls the display panel to show a food information interface, which includes a food addition control. In response to triggering the food addition control, the control panel displays the information input interface. Upon obtaining food information input based on the food information interface, it determines that an increase in stored food has been detected in the storage area, and generates and stores the input information for the stored food based on the food information. By interacting with the user through the display panel, the control device can quickly determine the addition of stored food based on the user's interaction process and quickly and accurately obtain information such as the food type of the stored food, thus improving the user experience.

[0098] In some embodiments, the control device is further configured to perform the following process: before predicting the storage conditions of the stored food based on its type, when receiving information from a user about adding a new stored food item via a display panel or label scanner (such as a barcode scanner), it determines whether other stored foods of the same type as the newly added food item exist in each storage area. If other stored foods of the same type exist, the storage area of ​​those other stored foods is recommended as the storage area for the newly added food item, so that the user can store the newly added food item in the recommended storage area. This method allows similar types of food to be stored in the same area as much as possible, reducing the subsequent adjustment of the cooling capacity of each storage area and lowering the energy consumption of the refrigeration equipment. Furthermore, it can improve the intelligence of the refrigeration equipment and enhance the user experience.

[0099] In some embodiments, such as Figure 8 As shown, in step S10, the control device predicts the storage conditions of the stored food based on the type of food being stored, and is configured to execute the following steps:

[0100] S11: Obtain the entry information of stored food in the storage area. The entry information shall include at least the food type of the stored food.

[0101] The control device acquires the recorded information of the stored food in the storage area. This recorded information is stored in the database when the food is stored in the corresponding storage area of ​​the refrigeration equipment, and includes at least the type of food. The recorded information can be obtained by scanning the information tags of the stored food with a control label scanning device, or by receiving user input through the display panel. The specific process is as described above and will not be repeated here.

[0102] S12: Based on the food type and environmental information of the storage area in each storage area, predict the storage conditions of the food.

[0103] It's important to understand that different storage zones within a refrigeration unit are located in different areas, have different storage functions, and may have varying temperature and humidity ranges. In other words, the environmental information within each storage zone differs, which in turn affects the spoilage rate of the stored food. For example, the temperature and humidity ranges in the freezer compartment are lower than those in the refrigerator compartment, and the temperature and humidity ranges in different storage zones within the refrigerator compartment also differ.

[0104] To improve the storage effectiveness (i.e., freshness and storage time) of food in different storage areas, the control device can predict the storage conditions of the food based on the type of food stored in each storage area and the environmental information of the storage area. The environmental information of the storage area includes at least the temperature and humidity information (i.e., temperature and humidity), which is obtained in real time by temperature and humidity sensors installed within the storage area. Figure 9 As shown, a label scanner can be installed on the inner wall of the container, and temperature and humidity sensors can be installed in each storage area to detect the temperature and humidity information of the storage area in real time.

[0105] For example, the type of food to be stored and the environmental information of the storage area can be input into a food storage prediction model to predict storage conditions, thus obtaining storage conditions that meet the storage requirements of the food. The model is trained using multiple food storage data sets, including the storage effects of different types of food under different storage conditions and environmental information. This increases the diversity of training data for the food storage prediction model, improves its prediction accuracy, and ultimately enables more accurate predictions of storage conditions.

[0106] In this embodiment, when the control device detects the information label of the stored food, it controls the label scanning device to scan the information label. The device determines the recorded information of the stored food in the storage area through the food information associated with the information label. This recorded information includes at least the food type. Then, based on the food type of the stored food in each storage area and the environmental information of the storage area, the storage conditions for the stored food are predicted. This process clarifies the process of determining the recorded information of the stored food, i.e., the food type. The relevant information of the stored food can be quickly determined through the label scanning device or display panel, making the operation simple and the information highly accurate. When predicting the storage conditions of the stored food, the influence of the environmental information of the storage area on the food storage effect is considered, which can improve the accuracy of the storage conditions and thus improve the precision of subsequent temperature and humidity control.

[0107] In some embodiments, the information entered for stored food also includes recommended storage conditions, production date, and shelf life. In step S12, the control device predicts the storage conditions for the stored food based on the food type in each storage area and the environmental information of the storage area where the stored food is located, and is configured to perform the following steps:

[0108] S121: Determine the pre-storage freshness of the food before it is stored in the storage area based on the food type, production date, and shelf life of the food.

[0109] In this embodiment, the information entered for stored food also includes the type of food, recommended storage conditions, production date and shelf life, as well as the transportation information of the stored food, such as transportation time and temperature and humidity information during transportation (which can be estimated based on the weather during transportation).

[0110] It's important to understand that food freshness refers to the degree to which food retains its inherent quality attributes during production, processing, transportation, storage, and sales. Before food is placed in refrigeration for storage, its freshness affects its subsequent storage requirements. Foods of the same type but with different levels of freshness require different storage conditions. For example, highly ripe fruits require different temperature and humidity levels than unripe fruits, and the lower the freshness of meat, the lower the required temperature.

[0111] After receiving the information on the stored food, the control device determines the freshness of the food before it is stored in the storage area based on the food type, production date, shelf life (and the transportation status of the stored food) in the information, thereby improving the accuracy of the freshness before storage.

[0112] For example, the control device can use the food type, production date, shelf life (and transportation details) of the stored food as input, and directly use a pre-trained first freshness model to predict freshness, obtaining the pre-storage freshness of the food before it is placed in the storage area. This method is simple and highly accurate. By using basic information about different types of food (such as food type, production date, and shelf life) and historical logistics data (such as transportation details), statistical analysis or neural network training can be performed to obtain a first freshness model for freshness prediction, which can improve the model's accuracy and enable subsequent accurate predictions of pre-storage freshness.

[0113] S122: Based on the type of food to be stored, its freshness before storage, recommended storage conditions, and environmental information of the storage area where the food is stored, predict the storage conditions for the food.

[0114] To accurately assess the impact of environmental information on the storage conditions of stored food, the diversity of environmental information can be increased. In this embodiment, the environmental information of the storage area includes the temperature and humidity information and gas information (i.e., the concentration of different gases in the storage area) of the storage area where the stored food is located. This gas information can be detected by other sensors installed in the storage area.

[0115] It's important to understand that varying temperatures and humidity levels, as well as the gases emitted by different foods, affect the rate of food spoilage. For example, some foods release specific gases (such as ethylene, ammonia, and carbon dioxide) during ripening and spoilage, which accelerate the spoilage of other normally stored foods. Different types of food produce different types of gases, and foods of varying freshness also produce different concentrations of these gases. In other words, differences in temperature and humidity ranges within storage areas, along with variations in the types and quantities of other stored foods within those areas, all have different impacts on the spoilage rate of the stored food.

[0116] To improve the storage effect of food in different storage areas, after determining the freshness of the food before it is stored in the storage area, the control device predicts the storage conditions of the food in real time based on the food type, freshness before storage, recommended storage conditions, and environmental information (such as temperature, humidity and gas information) of the storage area where the food is stored.

[0117] For example, the type of food to be stored, its freshness before storage, recommended storage conditions, and environmental information of the storage area where the food is located can be used as input. A pre-trained food storage prediction model can then be used to predict storage conditions that meet the storage requirements of the food. The model is trained using multiple food storage data sets, including the storage effects of different types and freshnesses of food under different storage conditions and environmental information. By increasing the diversity of training data for the food storage prediction model, the prediction accuracy can be improved, resulting in more accurate predictions of storage conditions. In other embodiments, the recommended storage conditions from the entered information of the stored food can also be directly used as the storage conditions for that food.

[0118] In this embodiment, the control device determines the pre-storage freshness of the food before it is stored in the storage area based on the food type, production date, and shelf life. Then, based on the food type, pre-storage freshness, recommended storage conditions, and environmental information of the storage area, it predicts the storage conditions for the food. By considering the impact of food type, pre-storage freshness, and environmental information on the food storage conditions, the accuracy of storage condition prediction is improved.

[0119] In other embodiments, the control device is further configured to: when it detects changes in environmental information within the storage area exceeding a preset threshold, such as detecting an increase in the amount of food stored in the storage area (i.e., an increase in the quantity of food), or detecting that the temperature and humidity in the storage area exceed a threshold, or detecting changes in gas information in the storage area exceeding a threshold, the control device predicts the storage conditions of each stored food within the storage area based on the type of food, its freshness before storage, recommended storage conditions, and the environmental information of the storage area where the stored food is located. Then, based on the storage conditions of each stored food within the storage area, it determines the amount of cooling capacity that needs to be increased or decreased in that storage area and the cooling priority of each storage area, so as to perform graded and zoned control of the temperature and humidity of each storage area through the refrigeration system. During the operation of the refrigeration equipment, the changes in environmental information in each storage area are detected in real time, thereby updating the storage conditions of the stored food in real time, achieving real-time and precise control of the temperature and humidity of the storage area, and further improving the food storage effect.

[0120] In some embodiments, each storage area is equipped with an environmental monitoring device. For example... Figure 10 As shown, in step S20, the control device determines the amount of cooling capacity that needs to be increased or decreased in each storage zone and the cooling priority of each storage zone, and is configured to perform the following steps:

[0121] S21: Environmental information of each storage area is obtained by detecting environmental monitoring devices in each storage area. The environmental information includes temperature and humidity information and the quantity of food in the storage area.

[0122] The control device can detect environmental information of each storage area through environmental monitoring devices in each storage area. The environmental information includes temperature and humidity information and the quantity of food in the storage area.

[0123] In this embodiment, each storage area is equipped with an environmental monitoring device, which includes a temperature and humidity sensor. Each storage area is equipped with a temperature and humidity sensor to detect the temperature and humidity information of each storage area. Figure 7 As shown. The environmental monitoring device may also include an image acquisition device, such as a camera or infrared device, for acquiring images of food in each storage area to determine the quantity of food in each storage area. In other embodiments, the quantity of food in each storage area can be determined based on the recorded information of the stored food, which also records the storage area where the stored food is located. By statistically analyzing all the storage areas containing the stored food in the refrigeration equipment, the quantity of food in each storage area can be quickly and accurately determined.

[0124] S22: Based on the quantity of food, temperature and humidity information, and storage conditions of the food in each storage area, determine the amount of cooling capacity that needs to be increased or decreased for each storage area.

[0125] It is important to understand that the required cooling capacity varies depending on the quantity of food in the same area; the more food and the higher the density, the greater the cooling capacity required. Similarly, different temperatures and humidity levels necessitate different adjustments to the required cooling capacity. Therefore, the control device needs to determine the necessary increase or decrease in cooling capacity for each storage area based on the quantity of food, temperature and humidity information, and storage conditions within each storage zone.

[0126] This process may involve comparing the storage temperature and humidity of the stored food with the current temperature and humidity information of the storage area to predict the required cooling capacity to adjust the storage temperature and humidity from the current information. Specifically, it involves determining the difference between the current temperature information and the storage temperature to obtain the temperature difference, and determining the difference between the current humidity information and the storage humidity to obtain the humidity difference. The cooling capacity is then determined based on the temperature difference and the quantity of food, and the humidity control amount is determined based on the humidity difference.

[0127] Specifically, the required cooling capacity for each storage area under different temperature increments can be pre-calibrated to obtain cooling capacity calibration data. After determining the temperature difference between the current temperature information of the storage area and the storage temperature, this temperature difference is matched with the temperature increment in the cooling capacity calibration data. The cooling capacity required for the matched temperature increment is used as the initial cooling capacity for that storage area. Based on the measured data, different amplification factors are pre-calibrated for different food quantity ranges to determine the amplification factor corresponding to the food quantity in that storage area. The amplification factor corresponding to the food quantity in that storage area is multiplied by the initial cooling capacity to obtain the required increase or decrease in cooling capacity for that storage area. If the temperature difference is negative, the required decrease in cooling capacity for that storage area is obtained; if the temperature difference is negative, the required increase in cooling capacity for that storage area is obtained.

[0128] S23: Determine the refrigeration priority of each storage area based on the type of each storage area and the type of food stored in each storage area.

[0129] The control device needs to determine the cooling priority of each storage zone based on its type and the type of food stored within. Different types of storage zones have different cooling priorities; for example, the cooling priority of storage zones in the freezer is higher than that in the refrigerator. Different food types also have different cooling priorities; fresh food has a higher cooling priority than cooked food. When there is a conflict between the cooling priority corresponding to the storage zone type and the cooling priority corresponding to the food type, the cooling priority of the storage zone type shall be given priority.

[0130] In a preferred embodiment, the control device determines the cooling priority of each storage zone based on the type of each storage zone and the type of food stored in each storage zone. It can also be configured to perform the following steps: determining the cooling priority of each storage zone based on its type, cooling capacity, food type, and pre-storage freshness. Different pre-storage freshness levels result in different cooling priorities for stored foods; the lower the pre-storage freshness (i.e., the less fresh the food), the higher the cooling priority of its storage zone, prioritizing the storage of foods with lower freshness. Similarly, a larger absolute value of the cooling capacity results in a higher cooling priority, prioritizing the storage of foods with high cooling requirements. This approach considers not only the influence of storage zone type and food type on the urgency of cooling demand but also the influence of cooling capacity and pre-storage freshness of the food on the urgency of cooling demand, enabling the determination of storage zone cooling priorities from multiple perspectives and improving the accuracy of cooling priority determination.

[0131] In this embodiment, environmental information of each storage area is detected by environmental monitoring devices within each storage area. This environmental information includes temperature and humidity information and the quantity of food in each storage area. Based on the quantity of food, temperature and humidity information, and storage conditions of the stored food in each storage area, the required increase or decrease in refrigeration capacity for each storage area is determined, improving the accuracy of refrigeration capacity. Based on the type of each storage area and the type of food stored in each storage area, the refrigeration priority of each storage area is determined, taking into account the impact of different storage area properties and different food types on the urgency of refrigeration demand, thus improving the accuracy of refrigeration priority for each storage area.

[0132] In some embodiments, the refrigeration system of the refrigeration equipment includes a compressor and a cold air delivery device for separately controlling the temperature and humidity of each storage area. For example... Figure 11 As shown, in step S30, the control device performs graded and zoned control of the temperature and humidity of each storage area through the refrigeration system, and is configured to execute the following steps:

[0133] S31: Determine the target frequency required for the compressor based on the increase or decrease in cooling capacity needed for each storage area.

[0134] After determining the required increase or decrease in cooling capacity for each storage zone, the control device sums up the required increase or decrease in cooling capacity for each storage zone to obtain the total cooling capacity, and determines the target frequency required by the compressor based on the total cooling capacity. The target frequency is the operating frequency of the compressor when the cooling capacity inside the box increases or decreases by the total cooling capacity.

[0135] Based on test data of the refrigeration equipment, the required compressor frequency change when increasing or decreasing the refrigeration capacity can be pre-calibrated to obtain refrigeration frequency data. After summing the required increase or decrease in refrigeration capacity for each storage area to obtain the total refrigeration capacity, the control device matches this total refrigeration capacity with the refrigeration frequency data. The compressor frequency change corresponding to the matched refrigeration capacity is used as the compressor frequency increment. The current operating frequency of the compressor is added to the frequency increment to obtain the target frequency required by the compressor. Determining the target frequency by summing the total refrigeration capacity and the pre-calibrated refrigeration frequency data is simple, convenient, and highly accurate.

[0136] S32: Control the compressor to work according to the target frequency, and deliver the corresponding cooling capacity to each storage area in sequence through the cooling capacity delivery device according to the cooling priority of each storage area, so as to realize the graded and zoned control of temperature and humidity of each storage area.

[0137] After determining the target frequency required by the compressor, the control device controls the compressor to operate at that target frequency. During this process, according to the cooling priority of each storage area, the cooling capacity is sequentially delivered to each storage area via the cold energy delivery device in the refrigeration system, achieving graded and zoned control of temperature and humidity in each storage area. The higher the cooling priority of a storage area, the more preferentially the cold energy delivery device outputs the required cooling capacity to that area.

[0138] The cooling capacity delivery device can be a multi-channel airflow distribution system based on an airflow channel design. Each storage zone has an independent airflow channel, which can be equipped with damper control and electric valves. While the compressor is operating, the cold air generated by the compressor is distributed to each storage zone through the multi-channel airflow distribution system to change the temperature and humidity of each zone, achieving zoned temperature and humidity control. When delivering cooling capacity through the multi-channel airflow distribution system, the corresponding cooling capacity is delivered to each storage zone according to its cooling priority, achieving graded temperature control of each storage zone.

[0139] In other embodiments, the cold air delivery device can also be refrigeration pipes laid in different storage areas within the container. The refrigeration pipes can hold refrigerant, and each storage area's refrigeration pipe is equipped with an electronic expansion valve or a thermostatic expansion valve. The refrigerant flow rate in each storage area can be controlled via these valves, allowing for individual regulation of the cooling capacity and pressure in each storage area, thus enabling zoned temperature control of different storage areas.

[0140] For example, suppose storage zone A in the refrigerator stores vegetables under the following conditions: temperature 4°C and humidity 70%. Storage zone B in the freezer stores frozen food under the following conditions: temperature -18°C. The temperature and humidity sensor in storage zone B currently detects a temperature of -17°C. The temperature and humidity sensor in storage zone A currently detects a temperature of 6°C and humidity of 65%. The cooling capacity of the refrigerator is n, while the cooling capacity of the freezer is m. Since m is less than n, the cooling priority of storage zone A is higher than that of storage zone B. When controlling the temperature and humidity of each storage zone, the control device controls the compressor's operating frequency according to the target frequency. When outputting cooling capacity through the cooling capacity delivery device, the damper or valve of storage zone A is opened, and the damper or valve of storage zone B is closed, prioritizing the delivery of cooling capacity n from storage zone A. When the temperature and humidity information of the storage area are stably maintained at 4℃ and 70%, the cooling capacity m of storage area B is then delivered through the flow conveying device.

[0141] In addition, each storage area is equipped with a humidification device, which controls and adjusts the humidity of each storage area separately. While determining the required increase or decrease in refrigeration capacity and the refrigeration priority of each storage area, it is also necessary to determine the required increase or decrease in humidity control for each storage area based on the storage conditions of the food stored within each area. When the corresponding refrigeration capacity is sequentially delivered to each storage area according to its refrigeration priority via the cold air delivery device in the refrigeration system, the control device is also configured to control the humidification device of each storage area to adjust humidity according to the required increase or decrease in humidity control, thereby achieving graded and zoned control of temperature and humidity in each storage area.

[0142] In this embodiment, the control device determines the target frequency required by the compressor based on the increased or decreased cooling capacity needed for each storage area, controls the compressor's operation according to the target frequency, and sequentially delivers the corresponding cooling capacity to each storage area through the cold energy delivery device according to the cooling priority of each storage area. This achieves graded and zoned control of temperature and humidity in each storage area. By adaptively adjusting the compressor's operating frequency based on the increased or decreased cooling capacity needed for each storage area, and dynamically adjusting the cooling capacity delivery control of the cold energy delivery device, the temperature and humidity of each storage area can be dynamically adjusted according to the food storage needs and the specific storage environment, achieving precise and energy-saving temperature control management.

[0143] In some embodiments, when determining the target frequency required by the compressor, the control device is further configured to perform the following process: acquire environmental information external to the refrigeration equipment (such as temperature and humidity information of the external environment), determine the target frequency required by the compressor based on the required increase or decrease in cooling capacity for each storage zone and the external environmental information, thereby improving the accuracy of the target frequency. Factors such as temperature and humidity of the external environment affect the operation of the compressor. For example, when the external temperature is high, the compressor requires higher power to maintain the internal low temperature. After determining the required frequency of the compressor based on the required increase or decrease in cooling capacity for each storage zone, the control device will appropriately increase the frequency based on the external ambient temperature to obtain the target frequency. Conversely, when the ambient temperature is low, after determining the required frequency of the compressor based on the required increase or decrease in cooling capacity for each storage zone, the control device will appropriately decrease the frequency based on the external ambient temperature to obtain the target frequency, thereby saving energy. Simultaneously, the control device will also predict the compressor's operating mode based on external environmental information. For example, the temperature control requirements differ between summer and winter, resulting in different compressor operating modes and corresponding operating frequencies.

[0144] In some embodiments, the control device is further configured to perform the following process: recording user behavior data of the refrigeration equipment, such as user usage frequency, food storage and retrieval time, door opening and closing frequency, and usage patterns during specific time periods (e.g., fewer door openings at night, more frequent openings during the day), for example, the duration and frequency at which users frequently store certain foods. The control device predicts user temperature control needs based on the user behavior data, and dynamically adjusts the compressor's operating frequency according to the predicted user temperature control needs, achieving dynamic compressor frequency control to adapt to user behavior habits, reduce equipment energy consumption, and improve user experience. For example, if the control device analyzes user behavior data and finds that the user frequently opens the door during a certain time period, and predicts that the user may use the refrigeration equipment and open the door frequently during that time period, the control device will reduce the compressor frequency in advance before that time period to maintain the temperature inside the refrigeration equipment while reducing energy consumption. In this embodiment, by learning user behavior data over a long period, the control module can adaptively generate personalized compressor control strategies, improving the control accuracy of the refrigeration equipment and further reducing energy consumption while ensuring food preservation.

[0145] In some embodiments, such as Figure 12 As shown, after step S10, after predicting the storage conditions of the stored food, the control device is further configured to perform the following steps:

[0146] S40: Record the storage conditions and storage time of the stored food into the food storage information entry, and monitor the temperature and humidity changes of each storage area in real time.

[0147] After predicting the storage conditions for the food, the control device records the storage conditions and storage time into the food's data entry system, and monitors the temperature and humidity changes in each storage area in real time using temperature and humidity sensors. Once the control device determines the pre-storage freshness of the food before it is placed in the storage area, it also records this pre-storage freshness into its data entry system.

[0148] S50: Based on the storage conditions, pre-storage freshness, and temperature and humidity changes in the storage area where the food is stored, the freshness of the stored food is predicted to obtain the real-time freshness of the stored food.

[0149] It's important to understand that changes in ambient temperature and humidity affect freshness, altering the rate at which food loses its freshness. For example, for milk, the recorded information indicates recommended storage conditions of 2-4°C and 60%-70% humidity; storing it above 6°C for more than two days will accelerate its spoilage. Furthermore, different storage conditions, the freshness before storage, and the length of storage time also influence the rate at which food loses its freshness.

[0150] To improve the accuracy of freshness prediction, the control device needs to periodically predict the freshness of the stored food during the storage process, based on the storage conditions, recommended storage conditions, freshness before storage, and storage time recorded in the information of the stored food, as well as the temperature and humidity changes in the storage area where the stored food is located. This prediction will obtain the real-time freshness of the stored food during the storage process.

[0151] In this embodiment, a second freshness model can be trained based on different types of food and varying freshness data. This freshness data includes changes in freshness under different storage conditions, recommended storage conditions, pre-storage freshness, storage time, and temperature and humidity variations. During food storage, the control device uses the storage conditions, recommended storage conditions, pre-storage freshness, storage time, and temperature and humidity variations in the storage area as model inputs. It directly uses the second freshness model to predict freshness, obtaining real-time freshness during storage, which is convenient and accurate. In actual use, the control device also records user feedback on the freshness of stored food and optimizes the parameters of the first and second freshness models based on this feedback until the predicted freshness matches the user feedback. By continuously optimizing the algorithm through machine learning and adjusting the freshness judgment criteria based on user feedback, the accuracy of recognition is gradually improved.

[0152] In an optimized embodiment, considering that gases in the storage area affect food freshness, and that other gases, such as ethylene gas, can characterize the ripeness or spoilage of food, additional sensors can be installed in each storage area. When predicting freshness, the gas concentration information collected by these other sensors can be directly used as the information for freshness prediction, further improving the accuracy of freshness prediction.

[0153] In other embodiments, images of the stored food can be acquired using image acquisition devices within each storage area. By performing food appearance recognition on these images, the real-time freshness of the stored food can be determined based on changes in its appearance (such as color, mold, shriveling, etc.). For example, color changes in tomatoes can serve as an indicator of ripeness or spoilage. The control device compares images from a database of images representing different storage conditions to determine the food's freshness. Furthermore, infrared sensors within each storage area can acquire the infrared spectrum of the stored food. Analyzing the food's chemical structure, such as changes in protein, fat, and sugar content, through the infrared spectrum analysis further determines its freshness. Using small infrared sensors to detect internal changes in food and determine freshness is particularly suitable for foods requiring high precision, such as fish and meat, as it can identify minute spoilage changes caused by temperature fluctuations.

[0154] S60: Provide food freshness alerts based on the real-time freshness of stored food.

[0155] After the control device predicts the real-time freshness of the stored food, it will also provide freshness reminders to the user based on the real-time freshness and the storage time in the refrigeration equipment. The freshness status of different stored foods can be displayed on the refrigeration equipment's display panel.

[0156] For example, the ideal storage conditions for apples are a temperature of 0-4℃ and a humidity of 90%-95%. Changes in temperature and humidity within the storage area affect their freshness. For instance, apples stored at around 25℃ for more than one day will have their freshness significantly affected; however, at a temperature of 10-15℃, the apples can maintain their freshness for up to 5 days. If the temperature in the apple storage area is 6℃ and the humidity is 85%, and the apples have been stored for 3 days, the control device will predict the freshness based on the storage conditions, the apples' freshness before storage, the storage time, and the temperature and humidity changes in the storage area. The device will then predict that the freshness is good. If the temperature in the apple storage area fluctuates within 3 days, and the temperature fluctuation exceeds 10℃, the control device will predict a rapid decline in the apples' freshness, prompting the user to consume the apples before they are fully fresh.

[0157] In this embodiment, after predicting the storage conditions of the stored food, the control device records the storage conditions and storage time into the food's information entry. It also monitors the temperature and humidity changes in each storage area in real time. Based on the storage conditions, pre-storage freshness, and temperature and humidity changes in the storage area, the device predicts the freshness of the stored food, obtaining its real-time freshness. Based on this real-time freshness, the device provides a freshness reminder. This solution promptly alerts users to the freshness of stored food, ensuring timely consumption and improving the user experience.

[0158] In some embodiments, the enclosure is also provided with a display panel. For example... Figure 13 As shown, in step S60, when issuing a food freshness reminder based on the real-time freshness of the stored food, the control device is configured to perform the following steps:

[0159] S61: Generate freshness reminder information for stored food based on its real-time freshness, storage time, and storage area.

[0160] After predicting the real-time freshness of the stored food during the storage process, the control device generates a freshness reminder message based on the real-time freshness, storage time, and storage area of ​​the stored food. That is, the freshness reminder message includes the real-time freshness, storage time, and storage area of ​​the stored food.

[0161] In a preferred embodiment, when the real-time freshness of the stored food exceeds a certain threshold, or when the storage time exceeds a certain threshold, the control device generates a freshness reminder message based on the real-time freshness, storage time, and storage area of ​​the stored food, so that subsequent freshness reminders can be issued. Reducing the frequency of freshness reminders minimizes the disturbance to users, improves user experience, and also reduces equipment energy consumption.

[0162] S62: Control the display panel to display freshness reminder information.

[0163] The control device controls the display panel to display freshness reminder information. In other embodiments, the refrigeration equipment is also equipped with a voice playback device; the control device controls the display panel to display freshness reminder information and / or controls the voice playback device to broadcast the freshness reminder information. In other embodiments, the freshness reminder information can also be sent to a user terminal so that the user can remotely know the freshness status of the stored food.

[0164] In this embodiment, based on the real-time freshness of the stored food, its storage time, and the storage area where it is located, a freshness reminder message is generated. The interactive device is then controlled to display and / or voice-broadcast the freshness reminder message, and / or send it to the user terminal. This freshness reminder message informs the user of the food's freshness status and allows them to locate the food for retrieval, ensuring timely access to the stored food and improving the user experience.
