Description

Technical Field

[0001] This utility model belongs to the field of refrigerator technology, specifically a refrigerator with display function. Background Technology

[0002] A refrigerator is a device used to store items that require low-temperature preservation. It is commonly found in home kitchens, supermarkets, restaurants, and various food processing and storage facilities. It uses a refrigeration system to maintain the internal temperature at a low level, typically between 0 and 4 degrees Celsius, to extend the shelf life of food and beverages and ensure their freshness and safety.

[0003] With the rapid development of smart home appliances, although some refrigerators have been equipped with basic smart functions, their application scenarios are still limited to basic operations such as temperature control and internal lighting control. In actual use, users often neglect to close the refrigerator door in time, resulting in continuous loss of cold air. This not only accelerates the risk of food spoilage but also causes unnecessary energy waste. In addition, when users store a large amount of food or items on the refrigerated tray, the lack of weight monitoring function makes it impossible to know the tray's load-bearing capacity. If the total weight of the items exceeds the tray's designed load-bearing capacity, the tray is very likely to be damaged. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please refer to Figure 1-3 ;

[0022] A refrigerator with a display function includes a cabinet body 1. The cabinet body 1 contains several support plates 2, each equipped with a pressure sensor 21. A tray 22 is placed above each pressure sensor 21 on each support plate 2. The pressure sensors 21 monitor the total weight of the items on the tray 22 in real time to prevent damage due to excessive weight. A door-closing motor 11 and a control module 12 are installed on the top of the cabinet body 1. A door 3 is located at the front of the cabinet body 1. A rotating shaft 4 is installed on one side of the door 3. The lower end of the rotating shaft 4 is rotatably connected to the bottom of the cabinet body 1, and the upper end of the rotating shaft 4 passes through the cabinet body 1 and connects to the door-closing motor 11. The door-closing motor 11 is electrically connected to the control module 12. When the door 3 is not closed, the control module 12 delays for 3 minutes before starting the door-closing motor 11. After the clock strikes, the door closing motor 11 drives the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it drives the cabinet door 3 to rotate together, thereby automatically closing the cabinet door 3 and avoiding unnecessary energy waste. The cabinet door 3 is provided with an embedded groove 5. The display screen assembly 6 is installed in the embedded groove 5 by screws. The pressure sensor 21 is electrically connected to the control module 12 and the display screen assembly 6. The pressure sensor 21 converts the pressure value it senses into an electrical signal and transmits it to the control module 12. The control module 12 receives these electrical signals and converts them into corresponding pressure values ​​through a preset algorithm. The processed pressure values ​​can be transmitted by the control module 12 to the display screen assembly 6 for display, so that users can intuitively understand the weight of the items on each tray 22 and adjust the distribution of items on overweight trays 22 in a timely manner.

[0023] In this embodiment, each support plate 2 is provided with 5 pressure sensors 21. The 5 pressure sensors 21 are respectively located at the center and four corners of the corresponding tray 22. The upper surfaces of the 5 pressure sensors 21 are horizontally aligned to ensure stable support for the tray 22.

[0024] In this embodiment, the display assembly 6 includes two pieces of glass 61 with the same external dimensions. A corresponding mounting groove 62 is provided on one side of each of the two pieces of glass 61 facing each other. A display 63 electrically connected to the control module is installed in the mounting groove 62. Encasing the display 63 with the glass 61 not only protects the display 63 but also prevents dirt and dust. The upper and lower ends of each of the two pieces of glass 61 are provided with corresponding fitting extensions 64. A U-shaped connector 65 is inserted into each of the two extensions 64, and the two pieces of glass 61 are bonded together by the two connectors 65. The connectors 65 and the extensions 64 are provided with several threaded holes 66 for screw sensing. Screws are then inserted through these holes. The display assembly 6 is fixedly connected to the cabinet door 3 through the threaded hole 66. During installation, the display 63 is first placed into the mounting groove 62 of one of the glass pieces 61. Then, the other glass piece 61 is aligned with the first glass piece 61 with its mounting groove 62 facing down, so that the two pieces fit together and wrap around the display 63. Next, the two connectors 65 are inserted into the upper and lower extensions 64 respectively to clamp the two glass pieces 61 so that they do not separate. Finally, the screws are tightened to lock the glass and connectors together. Finally, the display assembly 6 is placed into the embedded groove 5 and the screws are turned to install the display assembly 6 and the cabinet door 3 together.

[0025] In this embodiment, heat dissipation channels 67 are provided on both sides of the two glass plates 61. The heat dissipation channels 67 are connected to the embedded groove 5. The heat dissipation channels 67 are used for air inflow to avoid damage to the display 63 due to overheating.

[0026] In this embodiment, a Hall sensor 13 is provided on the cabinet body 1, and a magnetic component 31 is provided on the cabinet door 3. The Hall sensor 13 is electrically connected to the control module 12 and is used to sense whether the cabinet door 3 is closed. When the cabinet door 3 is closed, the magnetic component 31 on the cabinet door 3 will approach the Hall sensor 13 on the cabinet body 1, causing a change in the magnetic field around the Hall sensor 13. The Hall sensor 13 can capture this change and convert it into an electrical signal, which is then transmitted to the control module 12. The control module 12 analyzes the state of the cabinet door 3 based on the received signal strength and pattern. If the detected signal indicates that the Hall sensor is closed, the control module 12 will detect the change. If the Hall sensor 13 successfully senses the magnetic field of the magnetic component 31, it determines that the cabinet door 3 is closed. Conversely, if the Hall sensor 13 fails to sense the magnetic field of the magnetic component 31, it means that the cabinet door 3 is not completely closed. In this case, the control module 12 will not immediately start the door closing motor 11, but will set a 3-minute delay time to give the user enough time to manually close the cabinet door 3. If the cabinet door 3 is still not closed within this time, the control module 12 will start the door closing motor 11, which will drive the cabinet door 3 to rotate through the shaft 4 until it is completely closed, thereby avoiding unnecessary energy waste and ensuring the refrigeration effect.

[0027] In this embodiment, a proximity sensor 32 electrically connected to the control module 12 is provided on the cabinet door 3. When a person stands in front of the proximity sensor 32, the proximity sensor 32 transmits a signal to the control module 12, and the control module 12 lights up the control display 63 so that the user can understand the situation inside the cabinet 1.

[0028] In this embodiment, a temperature control device 14 is provided inside the cabinet 1 to control the temperature inside the cabinet 1. The temperature control device 14 is electrically connected to the control module 12 and the display 63. The temperature inside the cabinet 1 is adjusted by the temperature control device 14, and the temperature inside the cabinet 1 is displayed on the display 63.
