[0080] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0081] With the diversification of lifestyles and the popularization of IoT technology, refrigerators have become an important center for food storage and management in modern homes and shared living environments. The intelligent development of refrigerators has not only improved the convenience of food storage but also provided users with a more efficient food management experience.

[0082] However, in scenarios where multiple people share a refrigerator, problems such as unclear division of food storage rights among different users and difficulty in protecting personal food privacy are becoming increasingly prominent. Failure to implement refined access control and privacy protection may lead to accidental food retrieval, cross-contamination, or leakage of personal dietary preferences, thereby causing disputes and reducing user experience.

[0083] The existing technologies for managing access and privacy of food items in refrigerators generally fall into two categories: First, based on physical label recognition, users manually scan and register specific labels or QR codes on food packaging, setting visibility limits to restrict access to certain items. Second, based on manually setting storage compartments, the refrigerator interior is divided into multiple fixed compartments, with users assigning users to each compartment via a control panel or mobile app, thus achieving coarse-grained access control.

[0084] However, the above management methods have the following problems: In the first method, the process is cumbersome due to the need for users to manually paste, scan, and set labels. It relies heavily on user self-discipline, and labels are easily detached, damaged, or maliciously replaced, resulting in low reliability of access control and high management costs. In the second method, fixed partitions cannot flexibly adapt to dynamic and changing storage needs. Access control lacks features such as temporary authorization and time limits, and it also lacks an effective mechanism for hiding privacy information, posing a risk of information leakage. Therefore, in existing technologies, refrigerator food access management still relies on manual operation, resulting in poor system flexibility, inadequate privacy protection mechanisms, and an inability to meet users' needs for efficient, safe, and convenient food management.

[0085] One of the core concepts of this invention is that, in this embodiment, the refrigerator can receive a task instruction sent by a first user's user terminal; determine a second user who receives the task instruction, and grant the second user temporary access to use the first user's storage compartment, or grant the first user temporary access to use the second user's storage compartment; after recognizing that the second user or the first user has completed the task instruction, the refrigerator automatically closes the temporary access of the corresponding user. This invention achieves control over storage compartment permissions within the refrigerator in multi-user scenarios, allowing users to temporarily use other users' storage compartments as needed, or to allow other users to temporarily use their own storage compartments. This satisfies user needs while effectively protecting the security of food management and user privacy, thus improving the convenience and intelligent experience of using the refrigerator.

[0086] Reference Figure 1 The diagram illustrates a flowchart of an air conditioning control method according to an embodiment of the present invention. The method may specifically include the following steps:

[0087] Step 101: Receive the task instruction sent by the first user's user terminal;

[0088] The method of this invention can be applied to various types of smart refrigerators, including multi-door refrigerators, side-by-side refrigerators, commercial refrigerators, and networked refrigerators in smart home systems. The refrigerator's interior is divided into multiple compartments, each of which can be assigned to different users and has an independent access control mechanism. Users can send task commands to the refrigerator via a mobile app, voice assistant, or the refrigerator's built-in touchscreen, including but not limited to requests for food cleaning, access sharing, temporary borrowing, or errand storage.

[0089] In some examples, each user corresponds to at least one user terminal, including at least one master user and other general users. The master user has higher control authority than the other general users, meaning the master user can modify the control authority of other general users, including but not limited to control areas. When the first user (i.e., a general user) has a need, the refrigerator can receive task instructions sent by the first user's user terminal.

[0090] By receiving and processing user task instructions, the refrigerator can accurately identify user intentions, providing reliable input for subsequent permission allocation and task execution. This adaptive instruction receiving mechanism not only enhances the interactive intelligence and system robustness of the smart refrigerator, but also lays the technological foundation for achieving precise and secure compartment management.

[0091] Step 102: Determine the second user who accepts the task instruction, and grant the second user temporary permission to use the first user's object; or, grant the first user temporary permission to use the second user's object.

[0092] In this embodiment of the invention, after receiving the task instruction in step 101, the refrigerator can send the task instruction to all user terminals connected to the refrigerator and find users who are willing to accept the task instruction. When a user is willing to accept the task instruction, the user is identified as the second user, and temporary access to the first user's storage compartment is granted to the second user, or temporary access to the second user's storage compartment is granted to the first user.

[0093] In some examples, the first user can also actively assign, the main user designate, other users actively claim, or recommend based on historical behavior, among other mechanisms, to determine the second user to accept the task instruction. This temporary permission means that when a user obtains temporary permission for another user's instance, that user can only have that permission to open the instance once, within the time frame specified by the other user or the system's default timeframe.

[0094] In some examples, a user's use of temporary permissions can also be logged and pushed to associated users, such as the first user, the second user, or the main user, via in-site messages.

[0095] Through the above mechanism, users can achieve flexible permission sharing while effectively protecting the privacy and security of their food, and improving the collaborative efficiency and user experience of refrigerator use in a multi-user environment.

[0096] Step 103: After recognizing that the second user has completed the task instruction, close the temporary permissions of the second user; or, after recognizing that the first user has completed the task instruction, close the temporary permissions of the first user.

[0097] In this embodiment of the invention, the refrigerator can comprehensively determine whether a task has been completed using multiple technical means. For example, when the task instruction is "clean expired food from the first user's compartment," the refrigerator can acquire image information through an internal camera and use an image recognition algorithm to determine whether the target food has been removed. Simultaneously, a weight sensor detects whether the total weight of the compartment has changed as expected, and an infrared sensor monitors whether the placement of items in the compartment has stabilized. If the data from multiple sensors all meet the characteristics of task completion, the task is determined to have been completed.

[0098] In some examples, the refrigerator can also confirm the completion status based on user feedback. For instance, a second user can manually click the "Task Completed" button via a mobile app or the refrigerator's touchscreen. Upon receiving this signal, the refrigerator will perform a secondary verification using sensor data. If the data matches, the refrigerator will immediately revoke the temporary permissions corresponding to the first or second user.

[0099] In some examples, after permissions are revoked, an operation audit log can be automatically generated, recording the task execution result, the time permissions were revoked, and the triggering reason. This log is then uploaded to a cloud server for archiving. Simultaneously, notification messages indicating task completion and permission revocation can be sent to both the first and second users, ensuring that both are promptly informed of the task status change.

[0100] Through the above mechanism, the system achieves precise management of the lifecycle of temporary permissions, ensuring both the flexibility of permission allocation and the timeliness and reliability of permission revocation. This effectively protects the privacy and security of users' food while improving the efficiency of multi-user collaboration.

[0101] This invention provides a refrigerator control method. The method includes the refrigerator receiving a task instruction sent by a first user's terminal; identifying a second user who receives the task instruction and granting the second user temporary access to the first user's storage compartments, or granting the first user temporary access to the second user's storage compartments; and automatically deactivating the temporary access of the corresponding user after recognizing that either the second user or the first user has completed the task instruction. This invention enables control over storage compartment permissions within the refrigerator in multi-user scenarios. Users can temporarily use other users' storage compartments as needed, or allow other users to temporarily use their own storage compartments. This satisfies user needs while effectively protecting food management security and user privacy, enhancing the convenience and intelligent experience of using the refrigerator.

[0102] Reference Figure 2 The diagram illustrates a flowchart of another air conditioning control method provided by an embodiment of the present invention. The method may specifically include the following steps:

[0103] Step 201: Receive the task instruction sent by the first user's user terminal;

[0104] In this embodiment of the invention, users can send task instructions to the refrigerator via a mobile app, voice assistant, or the refrigerator's built-in touchscreen, including but not limited to requests for food cleaning, permission sharing, temporary borrowing, or purchasing and storage.

[0105] In some embodiments, the task instructions may include a cleanup instruction; the cleanup instruction is used to instruct the cleaning of the food items in the first user's corresponding compartment;

[0106] When the task instruction is a cleaning instruction, it can identify whether the food in each compartment of the refrigerator meets the cleaning conditions; when food that meets the cleaning conditions is identified, a cleaning reminder message is sent to the terminal device of the user corresponding to the food, and the cleaning reminder message is used to remind the user to clean the food.

[0107] In this embodiment of the invention, a multi-source sensor array and image acquisition device deployed inside the refrigerator can be used to periodically or trigger the automatic monitoring and intelligent identification of the food status in each compartment in order to determine whether it meets the preset cleaning conditions.

[0108] In some examples, the cleanup conditions are a multi-dimensional judgment system, mainly including:

[0109] Expired shelf life: For packaged food with RFID tags or QR codes, the system automatically calculates and determines whether it has expired by reading its stored production date and shelf life information;

[0110] Sensory spoilage characteristics: High-resolution cameras capture the visual appearance of food, such as discoloration, mold, and drying, and electronic nose sensors detect volatile organic compounds, such as amines and sulfides, to determine whether the food has spoiled.

[0111] Exceeding the storage time limit: For food items without a clearly defined expiration date but that are easily perishable, such as leftovers or cut fruit, the timer starts from when the food is placed in the container. If the preset safe storage time is exceeded, such as 72 hours, the food must be disposed of.

[0112] Abnormal condition detection: The weight sensor monitors whether there are any unexpected changes in the weight of the food, such as liquid leakage causing weight loss, or the humidity sensor detects that excessive humidity in the compartment may accelerate spoilage.

[0113] In some embodiments, the task instruction may include a borrowing instruction, which is used to instruct borrowing ingredients from other users;

[0114] In some embodiments, the task instructions may also include a purchasing instruction, which indicates that other users need to purchase ingredients on behalf of the user.

[0115] By receiving and processing user task instructions, the refrigerator can accurately identify user intentions, providing reliable input for subsequent permission allocation and task execution. This adaptive instruction receiving mechanism not only enhances the interactive intelligence and system robustness of the smart refrigerator, but also lays the technological foundation for achieving precise and secure compartment management.

[0116] Step 202: Send task delegation information to the user terminal of the main user of the refrigerator. The task delegation information is used to instruct the main user to delegate the task instruction.

[0117] In this embodiment of the invention, after receiving a cleaning instruction, the refrigerator automatically parses it and then sends task assignment information to the user terminal of a pre-defined main user of the refrigerator. The main user can be a home manager or the primary person in charge of a shared apartment. This task assignment information is transmitted via an encrypted communication link to ensure information security and user privacy. The task assignment information may include data in the following format: cleaning task details, such as the location of the target compartment, information on the food to be cleaned, the type of cleaning task, the identity of the task initiator (i.e., the first user), the task reception time, the expected completion time, and a list of recommended potential executors.

[0118] In some examples, task delegation information can be pushed to the primary user's terminal in various ways, such as mobile application pop-up notifications, SMS reminders, or voice assistant announcements. The primary user can choose how to handle the situation, such as directly assigning the task to a second user, rejecting the task delegation, modifying the task parameters and re-delegating, or accepting the task themselves.

[0119] In some examples, a multi-level delegation mechanism can also be supported. If the primary user does not respond within a preset time, the task delegation information can be automatically forwarded to the backup administrator or other family users can be notified in order of priority to ensure that the task is processed in a timely manner.

[0120] The above mechanism enables efficient and flexible delegation of cleanup tasks, which not only protects the decision-making power of the main user, but also ensures the timeliness of task processing through intelligent recommendation and multi-level notification mechanisms, laying a solid foundation for subsequent permission allocation and task execution.

[0121] Step 203: Receive delegation confirmation information sent by the user terminal of the primary user;

[0122] In this embodiment of the invention, the delegation confirmation information is the instruction information for the second user to receive the delegated task information. After receiving the confirmation information, the integrity of the information and the identity of the sender can be verified first to ensure that it originates from a legitimate primary user terminal and has not been tampered with.

[0123] In some examples, after the delegation confirmation information is verified, the information content is parsed and the task status is updated: if the main user has specified an executor, the task status can be changed to "delegated" and the process of assigning temporary permissions to the second user can be triggered; if the main user chooses to handle it themselves, the task status is changed to "processing" and the enhanced permissions of the corresponding object are granted to them; if the main user rejects the task, the status is changed to "rejected" and a task cancellation notification and reason explanation are sent to the first user.

[0124] Through the above mechanism, not only is the efficient and accurate reception and parsing of the main user's decisions achieved, but the reliability and continuity of the task delegation process are also ensured through multiple verification and timeout handling mechanisms, providing a clear basis for subsequent dynamic allocation of permissions and task execution.

[0125] Step 204: Based on the delegation confirmation information, determine the second user who accepts the task instruction, and grant the second user temporary access to use the first user's object; or, grant the first user temporary access to use the second user's object.

[0126] In this embodiment of the invention, after successfully receiving and parsing the delegation confirmation information from the primary user, the identity of the second user accepting the task instruction is determined. Once the second user is determined, a dynamic permission allocation mechanism is immediately activated, granting the second user temporary access to the target object, i.e., the first user's object. Alternatively, the first user is granted temporary access to use the second user's object.

[0127] In some examples, when the task instruction is a cleanup instruction, temporary access is granted to the second user to the cell containing the food items that need to be cleaned.

[0128] In some examples, when the task instruction is a borrowing instruction, temporary access is granted to the first user to the storage space containing the food items that need to be cleaned.

[0129] In some examples, when the task instruction is a purchasing instruction, temporary permission is granted to the second user to use the first user's inventory to store the purchased ingredients.

[0130] In some embodiments, when granting a first user temporary access to the second user's storage compartment, after detecting that the first user has opened the refrigerator, a first reminder message is output to the first user, the first reminder message being used to indicate the location of the second user's storage compartment;

[0131] or,

[0132] When granting temporary access to the first user's storage compartment to the second user, after detecting that the second user has opened the refrigerator, a second reminder message is output to the second user. The second reminder message is used to indicate the location of the first user's storage compartment.

[0133] In some examples, within embodiments of the present invention, multimodal sensing technology can be used to detect the opening status of the refrigerator door and the user's identity in real time. When a second user opens the refrigerator, devices such as a door magnetic sensor, infrared sensor, or built-in camera work together to quickly and accurately identify the second user's identity through multiple methods, including facial recognition and iris recognition. Upon successful identity verification, an alert mechanism is immediately triggered, generating and outputting a second alert message.

[0134] In some examples, the first or second notification message can be presented in the following ways:

[0135] Graphical guidance: The embedded touch screen inside the refrigerator door displays a three-dimensional layout of the refrigerator's internal storage space, and uses dynamic arrows or flashing effects to accurately mark the specific location of the first user's compartment, such as "the third shelf of the refrigerator compartment, the second one from the right";

[0136] Voice broadcast: The refrigerator’s built-in voice module provides clear and natural voice guidance information, such as “The compartment you want to access is located in the upper right corner of the refrigerator compartment, numbered A03”.

[0137] Light navigation: The LED indicator lights inside the compartment or the projection device inside the refrigerator cavity are activated to emit light of a specific color, such as blue, which illuminates the area around the target compartment or projects a path spot to guide the user's line of sight to quickly locate it.

[0138] At the same time, the user's terminal will also display a corresponding location prompt:

[0139] When granting the first user temporary access to the second user's storage space, a first reminder instruction is output to the first user's user terminal. The first reminder instruction is used to instruct the user terminal to output a third reminder message, which is used to indicate the location of the second user's storage space.

[0140] or,

[0141] When granting the second user temporary access to the first user's storage space, a second reminder instruction is output to the second user's user terminal. The second reminder instruction is used to instruct the user terminal to output a fourth reminder message, which is used to indicate the location of the first user's storage space.

[0142] In this embodiment of the invention, after successfully granting temporary access to the second user's grid to the first user, a first reminder instruction is simultaneously generated and sent to the mobile terminal bound to the first user, such as a smartphone or smartwatch. The first reminder instruction is a structured data packet containing detailed content, presentation requirements, and triggering logic of the third reminder information. The third reminder information helps the first user quickly and accurately locate the second user's target grid; its content is displayed on the user's terminal in the form of an image and text showing the location of the second user's grid.

[0143] In this embodiment of the invention, after successfully granting temporary access to the first user's grid to the second user, a second reminder instruction is simultaneously generated and sent to the mobile terminal bound to the second user, such as a smartphone or smartwatch. The second reminder instruction is a structured data packet containing detailed content, presentation requirements, and triggering logic of the fourth reminder information. The fourth reminder information helps the second user quickly and accurately locate the first user's target grid; its content is displayed on the user's terminal in the form of an image and text showing the location of the first user's grid.

[0144] In some examples, granting temporary permissions is achieved through the following technical means: First, a unique temporary permission token is generated and bound to the second user's identity, the target grid identifier, and permission parameters; then, the access control list is updated through the grid IoT lock control system, authorizing the token to access the target grid under specific conditions; finally, the permission information is synchronized to the refrigerator main control module and the cloud permission management center to ensure data consistency across multiple terminals.

[0145] The temporary permissions are subject to finely defined constraints, including but not limited to: the effective period of the permissions, such as only from 10:00 to 12:00 on the same day; only cleaning-related operations are allowed, such as only taking out food ingredients and prohibiting the putting in new items; the maximum number of operations allowed, such as only allowing the storage compartment to be opened once, etc.

[0146] Through the above mechanism, temporary permissions can be flexibly and accurately allocated while ensuring the security of the data storage and user privacy. This not only ensures the executability of the cleanup task, but also effectively prevents the abuse of permissions or unauthorized operations.

[0147] Step 205: After recognizing that the second user has completed the task instruction, close the temporary permissions of the second user; or, after recognizing that the first user has completed the task instruction, close the temporary permissions of the first user.

[0148] In this embodiment of the invention, multimodal perception and intelligent judgment technology is used to monitor and identify the user's execution status of task instructions in real time, and automatically trigger the permission revocation mechanism after confirming that the task is completed, so as to close the temporary access permissions of the corresponding user in a timely manner and ensure the security and privacy of the use of the object grid.

[0149] In some examples, the second user's temporary permissions are revoked after it is recognized that the second user has completed the cleanup command. For instance, by using multimodal perception and data fusion technology, the completion status of the second user's cleanup command can be automatically identified, and the second user's temporary permissions are revoked after it is recognized that the second user has completed the cleanup command.

[0150] This invention provides a refrigerator food management method, comprising: receiving a food cleaning instruction sent by a first user; sending task delegation information to the refrigerator's main user and receiving delegation confirmation information returned by the main user; determining a second user to perform the cleaning based on the confirmation information and granting temporary access to designated compartments to the corresponding user; outputting a reminder message for the authorized compartment location when the corresponding user opens the refrigerator or accesses the user terminal; identifying whether the food in each compartment of the refrigerator meets the cleaning conditions, and sending a cleaning reminder to the corresponding user if the conditions are met; and automatically revoking the temporary access of the corresponding user after the cleaning instruction has been executed. This invention achieves dynamic and secure management of refrigerator compartment permissions in a multi-user environment, improves the collaborative efficiency of food cleaning tasks, and ensures the hygiene of the refrigerator environment.

[0151] Reference Figure 3 The diagram illustrates a flowchart of another air conditioning control method provided by an embodiment of the present invention. The method may specifically include the following steps:

[0152] Step 301: Receive the task instruction sent by the user terminal of the first user;

[0153] In this embodiment of the invention, users can send task instructions to the refrigerator via a mobile app, voice assistant, or the refrigerator's built-in touchscreen, including but not limited to requests for food cleaning, permission sharing, temporary borrowing, or purchasing and storage.

[0154] In some embodiments, the task instructions may include a cleanup instruction; the cleanup instruction is used to instruct the cleaning of the food items in the first user's corresponding compartment;

[0155] When the task instruction is a cleaning instruction, it can identify whether the food in each compartment of the refrigerator meets the cleaning conditions; when food that meets the cleaning conditions is identified, a cleaning reminder message is sent to the terminal device of the user corresponding to the food, and the cleaning reminder message is used to remind the user to clean the food.

[0156] In this embodiment of the invention, a multi-source sensor array and image acquisition device deployed inside the refrigerator can be used to periodically or trigger the automatic monitoring and intelligent identification of the food status in each compartment in order to determine whether it meets the preset cleaning conditions.

[0157] In some embodiments, the task instruction may include a borrowing instruction, which is used to instruct borrowing ingredients from other users;

[0158] In some embodiments, the task instructions may also include a purchasing instruction, which indicates that other users need to purchase ingredients on behalf of the user.

[0159] By receiving and processing user task instructions, the refrigerator can accurately identify user intentions, providing reliable input for subsequent permission allocation and task execution. This adaptive instruction receiving mechanism not only enhances the interactive intelligence and system robustness of the smart refrigerator, but also lays the technological foundation for achieving precise and secure compartment management.

[0160] Step 302: Send an inquiry message for the task instruction to the user terminals of all users of the refrigerator; the inquiry message is used to ask whether to accept the task instruction;

[0161] In this embodiment of the invention, after receiving and parsing the task instruction initiated by the first user, a structured task query message is generated and broadcast to all user terminals bound to the refrigerator. This step aims to find a suitable user to execute the task through a collaborative mechanism, ensuring that the task can be responded to and processed in a timely manner. The query message may include the following key elements: task summary, task details, feedback options, etc.

[0162] Step 303: Receive task claim information sent by the second user;

[0163] In this embodiment of the invention, when the second user receives the inquiry message, if they are willing and able to perform the task, they send a task acceptance message through their user terminal. This acceptance message is a confirmation message that clearly expresses their willingness to accept the task.

[0164] Step 304: Based on the task assignment information, determine the second user who accepts the task instruction and grant the second user temporary access to the first user's object storage; or, grant the first user temporary access to the second user's object storage.

[0165] In this embodiment of the invention, after successfully receiving and verifying the task claim information of the second user, the user is identified as the executor of the cleaning instruction. A refined dynamic permission allocation mechanism is activated based on the specific type of the task, granting the second user temporary access to the storage space containing the food items to be cleaned; alternatively, granting the first user temporary access to the second user's storage space.

[0166] In some examples, step 304 includes the following scenarios:

[0167] When the task instruction is a borrowing instruction, the borrowing instruction is used to instruct the borrowing of ingredients from other users; grant the first user temporary access to the storage space where the ingredients borrowed by the second user are located;

[0168] In some instances, the task instruction is a borrowing instruction; the first user gains temporary access to the storage space where the second user's borrowed ingredients are located, and can borrow the second user's ingredients.

[0169] When the task instruction is a purchasing instruction, it indicates that other users need to purchase ingredients on behalf of the user; grants the second user temporary permission to use the first user's inventory to store the purchased ingredients.

[0170] In some instances, the task instruction is a purchasing instruction; the second user is granted temporary access to the first user's inventory to store the purchased ingredients. That is, after the second user helps buy something, it can be stored in the first user's inventory, or the second user can directly store the ingredients that the second user already has into the first user's inventory.

[0171] In some instances, when the task instruction is a cleaning instruction, temporary access is granted to the second user to the storage space containing the food items that need to be cleaned, allowing the second user to perform the cleaning.

[0172] In some embodiments, when granting a first user temporary access to the second user's storage compartment, after detecting that the first user has opened the refrigerator, a first reminder message is output to the first user, the first reminder message being used to indicate the location of the second user's storage compartment;

[0173] or,

[0174] When granting temporary access to the first user's storage compartment to the second user, after detecting that the second user has opened the refrigerator, a second reminder message is output to the second user. The second reminder message is used to indicate the location of the first user's storage compartment.

[0175] In some examples, within embodiments of the present invention, multimodal sensing technology can be used to detect the opening status of the refrigerator door and the user's identity in real time. When a second user opens the refrigerator, devices such as a door magnetic sensor, infrared sensor, or built-in camera work together to quickly and accurately identify the second user's identity through multiple methods, including facial recognition and iris recognition. Upon successful identity verification, an alert mechanism is immediately triggered, generating and outputting a second alert message.

[0176] In some examples, the second reminder message can be presented in the following ways:

[0177] Graphical guidance: The embedded touch screen inside the refrigerator door displays a three-dimensional layout of the refrigerator's internal storage space, and uses dynamic arrows or flashing effects to accurately mark the specific location of the first user's compartment, such as "the third shelf of the refrigerator compartment, the second one from the right";

[0178] Voice broadcast: The refrigerator’s built-in voice module provides clear and natural voice guidance information, such as “The compartment you want to access is located in the upper right corner of the refrigerator compartment, numbered A03”.

[0179] Light navigation: The LED indicator lights inside the compartment or the projection device inside the refrigerator cavity are activated to emit light of a specific color, such as blue, which illuminates the area around the target compartment or projects a path spot to guide the user's line of sight to quickly locate it.

[0180] At the same time, the user's terminal will also display a corresponding location prompt:

[0181] When granting the first user temporary access to the second user's storage space, a first reminder instruction is output to the first user's user terminal. The first reminder instruction is used to instruct the user terminal to output a third reminder message, which is used to indicate the location of the second user's storage space.

[0182] or,

[0183] When granting the second user temporary access to the first user's storage space, a second reminder instruction is output to the second user's user terminal. The second reminder instruction is used to instruct the user terminal to output a fourth reminder message, which is used to indicate the location of the first user's storage space.

[0184] In this embodiment of the invention, after successfully granting temporary access to the second user's grid to the first user, a first reminder instruction is simultaneously generated and sent to the mobile terminal bound to the first user, such as a smartphone or smartwatch. The first reminder instruction is a structured data packet containing detailed content, presentation requirements, and triggering logic of the third reminder information. The third reminder information helps the first user quickly and accurately locate the second user's target grid; its content is displayed on the user's terminal in the form of an image and text showing the location of the second user's grid.

[0185] Step 305: After recognizing that the second user has completed the task instruction, close the temporary permissions of the second user; or, after recognizing that the first user has completed the task instruction, close the temporary permissions of the first user.

[0186] In this embodiment of the invention, multimodal perception and intelligent judgment technology is used to monitor and identify the user's execution status of task instructions in real time, and automatically trigger the permission revocation mechanism after confirming that the task is completed, so as to close the temporary access permissions of the corresponding user in a timely manner and ensure the security and privacy of the use of the object grid.

[0187] In some examples, the second user's temporary permissions are revoked after it is recognized that the second user has completed the cleanup command. For instance, by using multimodal perception and data fusion technology, the completion status of the second user's cleanup command can be automatically identified, and the second user's temporary permissions are revoked after it is recognized that the second user has completed the cleanup command.

[0188] This invention provides a method for collaborative food management in a refrigerator. The method includes: receiving a food cleaning, borrowing, or purchasing instruction from a first user; sending task inquiry information to the terminals of all refrigerator users and receiving task claim information from a second user; determining the second user to perform the task based on the claim information and granting temporary access to designated storage compartments for that user, including granting access to storage compartments for borrowing food or storing purchased food for purchasing purposes; and outputting a reminder message for the authorized storage compartment location when the refrigerator is opened or the user operates the refrigerator via their terminal. This invention enables flexible collaboration of food management tasks and precise control of storage compartment permissions in a multi-user environment, significantly improving the convenience of refrigerator use and family collaboration efficiency.
