Description

An automatic door closing device for a compartmental refrigerator

technical field

The utility model relates to the technical field of refrigerated cabinets, in particular to an automatic door closing device for a compartmentalized refrigerated cabinet.

Background technique

With the improvement of social living standards, people pay more and more attention to food preservation, which makes the use of refrigerators more and more extensive. According to different needs, the structure of the freezer is also various. Among them, the grid freezer is gradually favored by people because of its independent compartments, no smell, and easy management. The compartmental refrigerator is provided with a plurality of refrigerated storage compartments arranged together, each refrigerated storage compartment is provided with an independent cabinet door, and the refrigerated storage compartments are separated by partitions.

Automatic return door hinges are mostly used in automatic doors, especially automatic doors with frequent opening and closing. Among them, the cabinet doors of compartmentalized refrigerators also use automatic return door hinges, which makes the cabinet doors more convenient to use and improves user experience. However, due to the need for cooling and heat preservation of the compartmentalized refrigerator, the larger the internal space, the more energy will be consumed, so the requirement for space utilization is very high. Therefore, the space gap between the two layers of refrigerated storage compartments of the compartmentalized freezer is very small. If the automatic return door hinge is installed in a normal way, the space gap between the two layers of refrigerated storage compartments is required to be larger than that of ordinary cabinet doors. The space utilization rate of the grid freezer is greatly reduced.
