Description

technical field

[0001] The invention relates to a refrigerating device, in particular to a refrigerating and freezing device and a drawer assembly thereof. Background technique

[0002] The drawer of the refrigerating and freezing device is generally arranged in a cylindrical body in a push-and-pull manner. With the improvement of food preservation requirements, it is necessary to form a good seal between the front panel of the drawer and the opening of the cylinder after the drawer is fully pushed into the cylinder, that is, it is necessary to make the front panel close to the opening of the cylinder.

[0003] For this reason, the existing refrigerating and freezing devices are equipped with complex mechanical or electromagnetic locking mechanisms to lock the drawer and the cylinder body, but the existing locking mechanisms are complex in structure and difficult to manufacture, cumbersome in operation and difficult to control, or high in cost . In addition, some locking m...
