Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable transportation technology, specifically a refrigeration and preservation device for long-term transportation of fruits and vegetables. Background Technology

[0002] Fruits and vegetables refer to both fruits and vegetables. When fruits and vegetables are transported over long distances, preservation devices are usually used to keep them fresh.

[0003] For example, a refrigerated preservation device suitable for long-term transportation of fruits and vegetables, as described in application number CN202221490513.1, includes a main body box, a lid, a fixed box, and refrigeration plates. The fruits and vegetables are placed in the fixed grid, and then the lid is closed. The refrigeration plates are then energized. When the current passes through, it can transfer heat from the cold end to the hot end, causing the temperature of the cold end to decrease and the temperature of the hot end to increase. Then, a micro motor is started to drive the rotating fan blades to rotate, so that the heat from the hot end is discharged from the inside of the fixed box through the exhaust channel, thereby achieving the purpose of refrigerating the fruits and vegetables inside the main body box, which is beneficial to ensuring the preservation effect of fruits and vegetables during transportation.

[0004] When using the above-mentioned refrigeration and preservation device, the fruits and vegetables that need to be refrigerated are placed in the inner cavity of the main box. Since the fruits and vegetables are placed directly in the inner cavity of the main box, the vegetables placed at the bottom of the main box will block the cold air at the bottom, resulting in poor refrigeration effect for the fruits and vegetables placed at the top of the inner cavity of the main box.

[0005] Therefore, we propose a refrigeration and preservation device for long-term transportation of fruits and vegetables to solve the problems mentioned above. Utility Model Content
