Detailed ways

The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

FIG. 1 is an exploded view of a door assembly 100 of the present invention.

Fig. 2 is a cross-sectional view of the door assembly in Fig. 1 .

As shown in Figures 1 and 2, the door assembly 100 includes:

The main body of the door includes an outer shell 10, an inner liner 20, an upper end cover 30 and a lower end cover 40 respectively connected to the top and bottom of the outer shell 10 and the inner liner 20. The compartment 50, the top wall 51, the bottom wall 52, the left side wall 53, the right side wall 54, and the rear wall 55 formed around the ice-making compartment 50, the shell 10, the upper end cover 30 and the ice-making compartment 50 A first wiring space 11 is formed between the side wall and the top wall 51;

The working part 60 is arranged inside the main body of the door;

The cable 70 has a first connection section 71 connected to the working part 60, a second connection section 72 extending out of the door body, and a connection between the first connection section 71 and the second connection section 72 The main line 73 between them, the main line 73 is located in the first wiring space 11 .

The door body assembly 100 is also provided with a thermal insulation layer. The heat insulation layer is generally after the shell 10, the inner lining 20, the cable 70 and other structures are assembled, and foaming technology is used to fill the heat insulating material such as rigid polyurethane between the shell 10 and the inner lining 20, and the cable 70 Then it is fixed in the insulation layer.

Because the outer casing 10 of the refrigerator is directly in contact with the external environment. In a high-temperature and high-humidity environment, if the temperature of the surface of the refrigerator casing 10 is too lower than the ambient temperature of the refrigerator, condensation is likely to occur, affecting user experience.

The insulation layer can play a role of heat insulation and isolate the temperature exchange inside and outside the refrigerator, so filling the insulation layer between the shell 10 and the inner liner 20 can well prevent the cold air from leaking out of the refrigerator. Under the action of the insulation layer, the cold air inside the box body 200 or the ice-making compartment 50 will basically not be conducted to the outer casing 10, and the temperature difference between the outer casing 10 and the refrigerator's external environment will not be too large, so that condensation will not occur. dew phenomenon.

Since the ice-making compartment 50 is formed by indenting the inner liner 20 toward the outer shell 10, the thickness of the insulating layer formed between the rear wall 55 of the ice-making compartment 50 and the outer shell 10 is much smaller than that of the outer shell 10. The thickness of the insulation layer formed between the outer shell 10 and the side wall of the ice-making compartment 50 . Also the thickness of the insulation layer formed between the rear wall 55 of the ice-making compartment 50 and the casing 10 is much smaller than the thickness of the insulation layer formed between the upper end cover 30 and the top wall 51 of the ice-making compartment 50 .

Because the heat insulation effect of the insulation layer is directly proportional to that of the insulation layer. If the insulation layer is too thin, it will not be able to effectively isolate the temperature exchange, and the temperature difference between the refrigerator shell 10 and the environment where the refrigerator is located will be too large, resulting in condensation.
