[0002] Currently, in the commercial refrigerator market, whether it's high-end air-cooled products or mid-to-low-end direct-cooled products, they only offer basic food preservation and storage functions, lacking the application of intelligent technologies and features. How to increase the storage time of items in refrigerators and slow down the rate of spoilage is a topic that the refrigerator manufacturing industry has always needed to study.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Please see Figure 1-5 This utility model provides a technical solution: an intelligent refrigerator with item recognition and zoned temperature control functions, including a refrigerator body 1 with multiple glass partitions 2 in the refrigerator compartment, the glass partitions 2 dividing the refrigerator compartment into multiple independent refrigerator compartments 3, a compressor 11 in the compressor compartment of the refrigerator body 1, an air duct 10 on the back of the inner liner of the refrigerator body 1, and an air vent 4 connected to the air duct 10 on the rear wall of each refrigerator compartment 3, with an air damper 9 at the air vent 4 to adjust the airflow; a temperature sensor 8 is installed in each refrigerator compartment 3; a camera 5 and an LED light are also installed in the refrigerator compartment of the refrigerator body 1. 6 and photosensitive sensor 7; the refrigerator body 1 is provided with a central processing control module 12 for processing information captured by camera 5, controlling the start and stop of compressor 11 and controlling the opening and closing of air damper 9, and the refrigerator body 1 is also provided with a wireless communication module 13 for sending image signals to the remote monitoring cloud platform and receiving signals from the remote monitoring cloud platform; the air damper 9 includes an air volume adjustment plate 91 that can slide vertically on the back of the air outlet 4, and the back of the air volume adjustment plate 91 is provided with meshing teeth in the vertical direction. The air damper 9 also includes a gear 92 that meshes with the meshing teeth on the back of the air volume adjustment plate 91, and the refrigerator body 1 is provided with a drive motor 93 that can drive the gear 92 to rotate.

[0017] Working principle:

[0018] Whenever the refrigerator compartment door is opened, the door opening signal is transmitted to the central processing control module 12. The central processing control module 12 controls the LED lighting 6 to illuminate the refrigerator compartment. After the photosensitive sensor 7 senses the light, it transmits the signal to the central processing control module 12, which then activates the camera 5 to start recording video of items being placed or taken out. After the refrigerator compartment door is closed, the LED lighting 6 turns off, and the camera 5 stops recording. The video or images captured by the camera 5 are processed by the central processing control module 12 and then transmitted to the remote monitoring cloud platform via the wireless communication module 13.

[0019] The remote monitoring cloud platform receives, parses, and processes incoming videos or images, analyzes and identifies stored items, sends the optimal environmental data of the stored items back to the refrigerator, completes data interaction, and finally sends the data back to the wireless communication module 13. The central processing control module 12 processes the returned signals and controls the start and stop of the compressor 11, controls the opening and closing of the damper 9, and detects the ambient temperature of the refrigerator compartment 3 through the temperature sensor 8, thereby adjusting the ambient temperature of the refrigerator compartment 3 where the items are located to meet the temperature requirements of different items.

[0020] The specific process of controlling the opening and closing of the damper 9 is as follows: the drive motor 93 drives the gear 92 to rotate, and the meshing gear 92 with the back of the air volume regulating plate 91 drives it to rise or fall vertically, thereby realizing the adjustment of the opening and closing of the damper 9 and the output of the cooling capacity of the air outlet 4.

[0021] The remote monitoring cloud platform consists of two parts. The first is a data storage and analysis system, which is used to parse and process the sent video or image data. First, the system stores the data in the server's memory, performs motion parsing, analyzes and identifies the data of food storage and retrieval, then extracts continuous motion sequences and classifies the motions. For each extracted continuous motion sequence, multiple frames are randomly selected to detect the type and quantity of food. Detecting multiple frames simultaneously can alleviate the problem of hands occluding objects to some extent. The second part is a database, which compares the extracted video footage with the resources in the database to obtain the type of stored items, combines environmental data to obtain the optimal storage temperature, and finally sends the data back to the refrigerator.

[0022] Furthermore, the camera 5, LED light 6, and photosensitive sensor 7 are all located at the top inside the refrigerator compartment of the refrigerator body 1, and the photosensitive sensor 7 is close to the LED light 6, resulting in better shooting effect.

[0023] Furthermore, the angle between the optical axis of the camera 5 and the horizontal line is 45°, which is a reasonable shooting angle.

[0024] The smart refrigerator disclosed in this embodiment, which features item recognition and zoned temperature control, uses an LED light 6, a photosensor 7, and a central processing control module 12 to control a camera 5 to automatically capture images of items. The central processing control module 12 processes the video or images captured by the camera 5 and transmits them to a remote monitoring cloud platform via a wireless communication module 13 for analysis and processing. The system then sends the optimal environmental data for storing the items back to the refrigerator. After processing the returned signals, the central processing control module 12 controls the start and stop of the compressor 11, controls the opening and closing of the damper 9, and uses a temperature sensor 8 to detect the ambient temperature of the refrigerator compartment 3. This allows for the adjustment of the ambient temperature of the refrigerator compartment 3 where the items are located, meeting the temperature requirements of different items. It can provide different storage environmental temperatures for different items, extending the storage time of items, slowing down the deterioration of items, and improving the user experience.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
