[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a new type of silver-plated ice-making ice tray containing a copper cavity, comprising an ice tray body 1, wherein the ice tray body 1 comprises a plurality of small ice grids composed of an ice tray substrate 2, each small ice grid is provided with a plurality of welds 3, each weld 3 is welded by metal tin, a sandblasting layer 4 is provided on the surface of the substrate 2 and the welding surface of the ice tray body 1, the sandblasting layer 4 contains a plurality of sandblasting pits, a first alkali copper layer 5 is provided on the outside of the sandblasting layer 4, a second bright copper-plated layer 6 is provided on the outside of the first alkali copper layer 5, a first pre-silver layer 7 is provided on the outside of the second bright copper-plated layer 6, a second thick silver layer 8 is provided on the outside of the first pre-silver layer 7, and a protective layer 9 is provided on the outside of the second thick silver layer 8. The cavity structure of the refrigerated ice tray of the present embodiment is a non-planar complex joint surface. When the electric welding operation is performed, the residual solder glue is left in the gap of the product. The traditional electroplating structure cannot meet the requirements of the subsequent electroplating bonding force. There is peeling phenomenon during the subsequent product installation and use process, which affects the refrigeration effect of the machine. There may even be the dissolution and penetration of copper ions into the food, causing poisoning. In addition, due to the presence of metallic tin at the welding point, which is a flexible metal, direct electroplating on it will cause peeling when the machine is heated and cooled rapidly in the future. The refrigerated ice tray of the present embodiment has a higher degree of fusion between the plating layers and between the plating layers and the ice tray body, and a stronger bite force. The plating layer is not easy to peel off in a refrigeration environment, and the edible safety of the refrigerated ice tray is improved while ensuring the thermal conductivity of the refrigerated ice tray.
