[0002] Partitioned display cabinets are a type of display furniture used to display goods or items. They are usually set up in shopping malls, supermarkets, specialty stores and other places. They have the characteristics of solid structure, easy disassembly and assembly, and convenient transportation. Their main function is to attract consumers' attention and promote sales. Common types of partitioned display cabinets include shelf-type display cabinets, counter-type display cabinets, freezer-type display cabinets, etc. Among them, freezer-type display cabinets are mainly used to display perishable foods, cold drinks and other commodities. They are equipped with a refrigeration system inside to maintain the freshness and taste of the commodities.

[0003] When using existing energy-saving partitioned display cabinets, customers often forget to close the cabinet doors or the cabinet doors are not closed properly.
