[0002] A freezer, also known as a refrigerator or a cold storage cabinet, is a low-temperature device used for storing and preserving food, beverages and other items. It mainly reduces the internal temperature through a refrigeration system, thereby extending the shelf life of food and maintaining its freshness. The refrigeration system circulates a refrigerant (such as ammonia, freon, etc.) to absorb and discharge the heat inside the freezer, thereby reducing the internal temperature.

[0003] When the existing freezer is in use, the storage box is cooled by a refrigeration component. However, the storage box has a certain capacity. When using the freezer to store goods, the phenomenon that the storage box is not full may occur.
