Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a stratified cold air circulation device. Background Art

[0002] Refrigerator is generally used for transporting fresh and cold food. Because refrigerator has good thermal insulation performance, it can keep the temperature of some fresh and cold food at a lower level when transporting them, so that the fresh and cold food can rely on the lower temperature for a certain period of time without being damaged, ensuring that the fresh and cold food has sufficient time to be transported. Refrigerator is needed for storage in the processing of pork. Traditional refrigerator is just a sealed box with good thermal insulation. However, since the density of cold air is greater than that of hot air, cold air is easy to gather at the bottom of the refrigerator, while the fresh and cold food placed on the top of the refrigerator is rarely exposed to cold air for freezing. Therefore, when using traditional refrigerator, the fresh and cold food at the bottom is easy to be frozen better, while the fresh and cold food on the top of the refrigerator is poorer, which seriously affects the quality of some fresh and cold food, and in severe cases, it will cause damage and waste of fresh and cold food.

[0003] For example, a Chinese patent with publication (announcement) number CN209492902U discloses a stratified cold air circulation refrigerator for transporting pork, comprising an outer shell, a guide plate, ice cubes and a circulating air pump, wherein a cabinet door is rotatably mounted on the side of the outer shell via a hinge, a guide plate is welded to the inner wall of the outer shell, and an air vent is fixedly provided on one side of the bottom of the guide plate.

[0004] Although the above technical solution solves the corresponding technical problem, the above technical solution still has the following defects:

[0005] The guide plate of the above technical solution occupies a large space inside the shell, thus affecting the placement of pork. At the same time, when cold air is introduced into the shell, different amounts of cold air cannot be introduced into different compartments according to actual needs, thereby reducing practicality.
