Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted refrigerators, in particular to a heating mechanism for a double-opening vehicle-mounted refrigerator door. Background Art

[0002] Condensation on the refrigerator door is usually caused by temperature differences. When the outside air is humid and contacts the cold air inside the refrigerator compartment, the moisture will condense into water droplets, and the condensation phenomenon on the refrigerator door seriously affects the user's opening and closing of the refrigerator door. At present, the existing technology solves the condensation phenomenon of the refrigerator door mainly by setting a heating wire on the refrigerator door frame for heating, so as to prevent the occurrence of condensation. In the patent document of application number: 202322426474.X, a double-door car refrigerator is disclosed, which heats the gap between the two sealed side walls through a heating element at the same time, and then heats the air in the gap, so that the temperature at the gap is increased, thereby avoiding the occurrence of condensation. However, the connecting wire of the heating element is led to the outside through a pivot shaft passing through one side of the door, and there is no mechanism on the door to limit the connecting wire, resulting in that when the door is opened and closed, the connecting wire will flip with the opening and closing of the door. In this process, the shape of the connecting wire may change, thereby hindering the opening and closing of the door. Utility Model Content
