Description

Technical Field

[0001] This application relates to the field of table tennis cabinet technology, and in particular to a table tennis cabinet with variable temperature storage space. Background Technology

[0002] Ice cream display cases, as a type of storage equipment specifically designed for refrigerating and displaying frozen foods such as ice cream, have been widely used in various beverage shops, supermarkets, and convenience stores in recent years. These cases not only require excellent refrigeration performance to maintain the taste and quality of ice cream and other foods, but also an attractive display to draw consumers' attention.

[0003] Refrigeration efficiency is one of the key indicators for evaluating the performance of ice cream display cases (ball game cabinets). Traditional display cases typically use a single refrigeration system, which has relatively limited cooling effect. While using dual or multiple refrigeration systems to enhance cooling effect can improve performance, it also leads to an increase in overall size and creates unused space inside the equipment. In current technology, this unused space is usually used as storage compartments and does not have refrigeration function, thus failing to effectively utilize the refrigeration energy of the display case. To improve the refrigeration function of these storage compartments, their sealing needs to be adjusted accordingly to ensure refrigeration effectiveness. Summary of the Invention
