Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a magnetic suction door structure of refrigeration equipment. Background Art

[0002] Refrigeration equipment such as freezers and refrigerators are usually used to store daily refrigerated and frozen wine, food and other items for users. Their basic function is to refrigerate and keep the cabinet or box at an appropriate low temperature. The refrigeration system is generally composed of four basic components: a compressor, a condenser, a capillary tube or a thermal expansion valve, and an evaporator. When working, the compressor increases the gas pressure of the refrigerant to create liquefaction conditions. When passing through the condenser, it condenses and liquefies to release heat, then reduces the pressure and temperature when passing through the capillary tube, and then boils and vaporizes when passing through the evaporator to absorb heat. The refrigeration principle of refrigeration equipment is currently well known to technical personnel in the industry, such as a constant temperature refrigeration wine cabinet disclosed in the utility model patent with Chinese patent number CN202020278865.5, a back-push refrigeration module split wine cabinet disclosed in the utility model patent with Chinese patent number CN202022465317.6, and a new type of refrigerated wine cabinet disclosed in the utility model patent with Chinese patent number CN201520755850.2.

[0003] However, when the user closes the door forcefully, the door of the refrigeration equipment will bounce open due to the reverse force, causing the door to not be completely closed. If the user does not close the door again in time, the cold air inside the refrigeration storage chamber of the refrigeration equipment will leak out, causing not only the refrigeration system to be overloaded and resources to be wasted, but also affecting the refrigeration effect. At the same time, frost, ice, water leakage and other problems may occur inside the refrigeration storage chamber, seriously affecting the user experience.

[0004] Therefore, further improvement is necessary. Utility Model Content
