[0021] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0022] Figure 1 This is a schematic diagram of a refrigeration and freezing device provided by an embodiment of the present disclosure. Figure 2 Schematic diagram of the sensor and control module provided by the embodiment of the present disclosure. Figure 1-2 As shown,

[0023] The present disclosure provides a refrigeration device comprising a main body 1, a door 2 hingedly connected to the main body, and a storage chamber 3 disposed within the main body, and further comprising: a storage shelf, a sensor 7, and a control module 8. The storage shelf comprises a movable portion 4 and a storage device 5, configured to hold stored items and to move with the movable portion 4 when the door 2 is opened, thereby being pulled out of / pushed into the storage chamber 3; the sensor 7 is disposed in the storage chamber 3 and configured to sense the storage shelf; and the control module 8 is electrically connected to the sensor 7 and configured to activate refrigeration of the storage chamber 3 when the sensor 7 senses the storage shelf, and to deactivate refrigeration of the storage chamber 3 when the sensor 7 does not sense the storage shelf.

[0024] With this refrigeration device, the storage shelf can be pulled out / pushed into the accommodating cavity 3. By detecting whether the storage shelf is in the accommodating cavity 3, the refrigeration is turned off when the storage shelf is not in the accommodating cavity 3, which saves more energy.

[0025] Optionally, a sensor 7 is provided on the front sidewall of the bottom plate of the accommodating chamber 3 in an area corresponding to the connecting portion 6 and is configured to sense the storage device 5. A control module 8 is electrically connected to the sensor 7 and is configured to activate cooling of the accommodating chamber 3 when the sensor 7 senses the storage device 5, and to deactivate cooling of the accommodating chamber 3 when the sensor 7 does not sense the storage device 5. When the storage device 5 is pushed into the accommodating chamber 3 and the sensor 7 senses the storage device 5, the control module 8, which is electrically connected to the sensor 7, activates cooling of the accommodating chamber 3. When the storage device 5 is pulled out of the accommodating chamber 3 and the sensor 7 fails to sense the storage device 5, the control module 8 deactivates cooling of the accommodating chamber 3.

[0026] Optionally, sensor 7 is a pressure sensor. It has a simple structure and high accuracy. Optionally, sensor 7 is a distance sensor. This allows for non-contact detection, reduces damage to the sensor, and has a longer lifespan. Types of sensor 7 include, but are not limited to, those listed above.

[0027] Optionally, the sensor 7 is disposed within the storage cavity 3 and includes an infrared sensor and / or a camera. In this manner, the infrared sensor is relatively low-cost and highly sensitive, capable of detecting whether the storage shelf is within the storage cavity 3. The camera provides accurate sensing, capable of detecting not only whether the storage shelf is within the storage cavity 3 but also identifying the number and / or type of items on the storage shelf.

[0028] Optionally, the movable portion 4 is disposed outside the main body 1; the storage device 5 is connected to the movable portion 4 via a connecting portion 6 and is configured to hold stored items. The storage device 5 can be moved with the movable portion 4 when the door 2 is opened, and can be pulled out of / pushed into the accommodating cavity 3. In this way, the storage device 5 can be pulled out of the accommodating cavity 3 along with the movable portion 4. After the storage device 5 is pushed out of the accommodating cavity 3, it can be moved to any location, taken out of the corresponding items, and then pushed back into the accommodating cavity 3, making it convenient to use.

[0029] Optionally, the storage device 5 is located within the accommodating cavity 3 of the main body 1 and integrally connected to the movable portion 4 disposed outside the main body 1 via a connecting portion 6. When the door 2 is closed, the accommodating cavity 3 forms a sealed space, isolating the items placed therein from the outside world. When the refrigerator door 2 is opened, the storage device 5 can be pulled out of the accommodating cavity 3; when no longer needed, it can be pushed back into the accommodating cavity 3.

[0030] Alternatively, the accommodating chamber 3 can be used as a refrigerator. The storage device 5 can store vegetables, fruits, and other foods that need to be kept fresh. Alternatively, the accommodating chamber 3 can be used as a freezer. The storage device 5 can store foods that need to be frozen to prevent them from spoiling.

[0031] Optionally, the accommodating chamber 3 can be used as a storage room. When the accommodating chamber 3 is stopped from being cooled, some seasonings can be stored on the storage device 5 to save space in the kitchen.

[0032] Optionally, the storage device 5 can be pulled out from the accommodating cavity 3 and placed outside the main body 1. It can be used alone as a storage rack, and some larger items can be directly stored in the accommodating cavity.

[0033] Figure 3 This is a structural framework diagram of the control module provided by the embodiment of the present disclosure, such as Figure 3 As shown,

[0034] In some optional embodiments, the control module 8 is further configured to adjust the cooling parameters of the accommodating chamber 3 according to the number and / or type of items on the storage shelf. In this way, when the number and / or type of items on the storage shelf changes, the cooling parameters of the accommodating chamber 3 can be adjusted in a timely manner to maintain an optimal storage environment and improve storage efficiency.

[0035] Optionally, the refrigeration parameters include refrigeration capacity and / or refrigeration speed.

[0036] Optionally, the control module 8 includes: an identification unit 81 configured to identify the quantity and / or type of items on the storage shelf through image recognition technology.

[0037] Optionally, the sensor 7 is disposed in the accommodating cavity 3 and is a camera. The camera is used to take a picture of the storage shelf, and then image recognition is performed on the content of the picture to obtain the number and / or type of items on the storage shelf.

[0038] Optionally, the control module 8 includes a first refrigeration parameter control unit 82 and / or a second refrigeration parameter control unit 83. The first refrigeration parameter control unit 82 is configured to determine the storage temperature of the items based on the type of items on the storage shelf and adjust the cooling capacity of the accommodating chamber 3 accordingly. The second refrigeration parameter control unit 83 is configured to adjust the cooling speed of the accommodating chamber 3 based on the number of items on the storage shelf. In this way, different types of items stored on the storage shelf require different storage temperatures. The cooling capacity of the accommodating chamber 3 is adjusted based on the type of items on the storage shelf to control the internal temperature of the accommodating chamber 3, thereby maintaining an optimal storage environment and improving storage efficiency. Different numbers of items stored on the storage shelf require different cooling speeds. The cooling speed of the accommodating chamber 3 is adjusted based on the number of items on the storage shelf, allowing the accommodating chamber 3 to quickly reach the required cooling temperature, maintaining an optimal storage environment and improving storage efficiency.

[0039] Optionally, based on the type of items on the storage shelf and the optimal storage temperature of the type queried in the database, for example, if the items on the storage shelf are vegetables and the optimal storage temperature of vegetables queried in the database is 5-6 degrees, the cooling capacity of the accommodating chamber 3 is adjusted to make the temperature in the accommodating chamber reach 5-6 degrees.

[0040] Optionally, the database is pre-stored in a table format of common types of items and optimal storage temperatures.

[0041] Optionally, when multiple types of items are stored on the storage shelf at the same time, the intermediate value of the optimal storage temperatures of the multiple types of items is taken, and the cooling capacity of the accommodating cavity 3 is adjusted according to the intermediate value. In this way, the temperature tends to the average value of the optimal storage temperatures of the multiple items, ensuring the freshness of the multiple items.

[0042] Optionally, the number of items on the storage shelves can be graded, as can the cooling speed. For example, the number of items can be graded from 1 to 10, from small to large, and the cooling speed can be graded from slow to fast. Level 1 for the number of items corresponds to level 1 for the cooling speed, and so on, level 10 for the number of items corresponds to level 10 for the cooling speed. This simplifies control and facilitates cooling speed control.

[0043] Figure 4 Schematic diagram of the storage device provided by the embodiment of the present disclosure. Figure 4 As shown,

[0044] In some embodiments, the storage device 5 includes: a frame 50 and a shelf 51. The frame 50 includes a longitudinal supporting side panel 500 fixedly connected to the connecting portion 6; the shelf 51 is horizontally arranged on the longitudinal supporting side panel 500 and is configured to place stored items. The frame 50 serves as the main structure of the storage device 5 and can bear the entire load of the storage device 5. The longitudinal supporting side panel 500 of the frame 50 is fixedly connected to the connecting portion 6. In this way, the stability and safety of the storage device 5 can be effectively maintained. The shelf 51 is the loading structure of the storage device. Items that the user needs to store can be placed on the shelf 51.

[0045] Optionally, the shelf 51 is a flat shelf. Articles with packaging boxes can be placed thereon, and the size of the packaging boxes is not restricted like this.

[0046] Optionally, shelf 51 is a tray-style shelf with upwardly extending baffles around the edges of the flat plate. This prevents irregularly shaped items placed on shelf 51 from sliding or falling along the edges of shelf 51 during movement of the storage device. Shelf 51 can be circular, rectangular, or polygonal in shape, providing users with a more engaging experience and enhancing the usability of the storage device 5.

[0047] In some embodiments, the movable portion 4 includes: a movable chassis 40 and a roller 41. The movable chassis 40 is arranged below the accommodating chamber 3 and is fixedly connected to the connecting portion 6; the roller 41 is arranged at the lower part of the movable chassis 40. The movable chassis 40 is fixedly connected to the connecting portion 6. In this way, it can bear the load of the frame and improve the stability of the storage device 5. A sliding roller 41 is installed at the lower part of the movable chassis 40. When the storage device 5 is pushed, it moves with the movement of the roller 41. When the door body 2 is opened and the storage device 5 is pushed into the accommodating chamber 3, the movable chassis 40 is located in the gap between the bottom plate of the accommodating chamber 3 and the ground. In this way, the storage device 5 is placed in the accommodating chamber 3. At this time, the door body 2 is closed to start the operation of the refrigeration system for the accommodating chamber 3.

[0048] In some embodiments, the connecting portion 6 is fixedly connected to the front side of the longitudinal support side panel 500 and the side of the movable chassis 40. This secures the storage device 5 and the movable portion 4 together as a single unit. The secure connection provides high strength, preventing the connection from loosening and potentially causing damage when the load on the storage device 5 changes.

[0049] In some embodiments, the connecting portion 6 protrudes from the longitudinal supporting side panels 500 and the movable chassis 40. In this way, when the storage device 5 is pushed back into the accommodating chamber 3, the longitudinal supporting side panels 500 can be placed inside the accommodating chamber 3, ensuring that the storage device 5 can be fully pushed into the accommodating chamber 3 without affecting the closing of the door body 2.

[0050] Figure 5 This is a schematic diagram of the door structure provided by the embodiment of the present disclosure. Figure 5 As shown,

[0051] In some embodiments, the door body 2 includes a groove 20 disposed on the inner wall of the door body 2 in an area corresponding to the connecting portion 6 and configured to accommodate the connecting portion 6. Because the connecting portion 6 protrudes from the storage device, the groove 20 is provided on the door body 2 in an area corresponding to the connecting portion 6 to accommodate the connecting portion 6. When the storage device is pushed into the accommodating cavity 3 and the door body 2 is closed, the protruding connecting portion 6 is placed in the groove 20. This allows the inner sidewall of the door body 2 to completely fit against the outer sidewall of the corresponding accommodating cavity 3 when the door body 2 is closed, ensuring the sealing of the accommodating cavity 3.

[0052] Optionally, sealing strips are provided on the inner edge of the door body 2 and the edge of the groove to further ensure the sealing of the accommodating cavity 3 and prevent the cold air from leaking out.

[0053] Figure 6 It is a schematic diagram of a connection portion provided by another disclosed embodiment. Figure 7 Schematic diagram of the notch in the bottom plate of the accommodating cavity provided by another disclosed embodiment; Figure 6-7 As shown,

[0054] In some embodiments, the connecting portion 6 is fixedly embedded in the lower end of the longitudinal support side panel 500 and the upper end of the movable chassis 40. Corresponding grooves are provided at the lower end of the longitudinal support side panel 500 and the upper end of the movable chassis 40, and the connecting portion 6 is fixedly embedded in the grooves. In this case, the surface of the connecting portion 6 is flush with the front side of the longitudinal support side panel 500 and the side of the movable chassis 40, eliminating the need for a groove in the door body 2. Thus, when the door body 2 is closed, the inner sidewall of the door body 2 directly and tightly mates with the outer sidewall of the corresponding storage cavity 3, simplifying the manufacture of the door body 2.

[0055] Optionally, a notch 30 may be provided on the bottom wall of the accommodating chamber 3, in an area corresponding to the connecting portion 6, and the notch 30 may completely accommodate the connecting portion 6. This allows the storage device 5 to be fully pushed into the accommodating chamber 3, ensuring that the accommodating chamber 3 forms a sealed storage space after the door body 2 is closed.

[0056] Optionally, a sealing strip is attached to the edge of the notch 30 to further ensure the sealing of the accommodating chamber 3, prevent external air and bacteria from entering the accommodating chamber 3 to contaminate the items placed therein, and prevent the leakage of cold air.

[0057] In some embodiments, the frame 50 further includes: auxiliary support side panels 501, upper connecting plates 502, and hanging components 503. The auxiliary support side panels 501 are located at the other end of the shelf 51, opposite the longitudinal support side panels 500, and are fixedly connected to the shelf 51, configured to support the shelf 51. The upper connecting plates 502 are parallel to the shelf 51 and fixedly connected to the top ends of the longitudinal support side panels 500 and the auxiliary support side panels 501. In addition to the longitudinal support side panels 500, the frame 50 of the storage device 5 also includes auxiliary support side panels 501, located at the other end of the shelf 51, opposite the longitudinal support side panels 500. The auxiliary support side panels 501 share the load of the shelf 51, ensuring its stability and security, and preventing the connection between the shelf 51 and the longitudinal support side panels 500 from breaking when items placed on the shelf 51 are too heavy. The upper connecting plates 502 are located at the top ends of the longitudinal support side panels 500 and the auxiliary support side panels 501. This further improves the robustness of the frame 50, effectively preventing the storage device 5 from shaking during movement, which could cause the center of gravity of the storage device to become unstable. Optionally, the longitudinal support side panels 500, the auxiliary support side panels 501, and the upper connecting plate 502 can be integrally formed during the manufacturing process, resulting in an aesthetically pleasing structure and preventing the risk of the frame 50 breaking at the connection due to insufficient strength during use.

[0058] like Figure 4 As shown, the upper connecting plate 502 is provided with a hanging member 503 for hanging items. During use, the user can sort and bag items for storage and hang them on the hanging member 503. This rational use of the space above the accommodating cavity 3 for storage and storage improves the utilization rate of the storage device 5, and is convenient to use and easy to hang and take out.

[0059] It should be understood that the refrigeration and freezing equipment can be a refrigerator, a freezer, or a wine cabinet. The refrigerator, freezer, or wine cabinet can use a storage device to store food or wine. This refrigeration and freezing equipment has a reasonable structure, can more effectively utilize space, save users' time, and has broad market prospects.

[0060] The present disclosure also provides a storage device comprising a main body, a door hingedly connected to the main body, and a storage cavity disposed within the main body. The storage device further comprises a movable portion, a storage device, and a connecting portion. The movable portion is disposed on the exterior of the main body; the storage device is connected to the movable portion via a connecting portion and is configured to hold stored items. The storage device moves with the movable portion when the door is opened, allowing it to be pulled out of / pushed into the storage cavity. Alternatively, the storage device may be a kitchen cabinet, where cooking utensils and condiments are stored on the storage device and placed within the storage cavity. This prevents excessive fumes and dust from contaminating the kitchenware, facilitating cleaning and sorting. Alternatively, the storage device may be a wardrobe. Clothes of different seasons or types can be placed on the storage device for easy labeling and retrieval. The storage device can be pulled out of the storage cavity to a location where a dressing mirror is located, facilitating clothing selection and matching. After use, it can be returned to the storage cavity. Alternatively, the storage device may be a shoe cabinet, facilitating the storage and matching of shoes. Alternatively, the storage device may be a bookcase. It is convenient to place different books in categories. You can also place multiple books on the storage device and push them to the rest area for reading, saving the time of going back and forth between the bookshelf and the rest area.
