Embodiment Construction
[0043] figure 1 It is a schematic side view of a refrigerator 100 according to an embodiment of the present invention, and only shows the refrigerated liner 130 corresponding to the upper refrigerated compartment. The refrigerator 100 in the embodiment of the present invention includes a box body 110 and a door body (not shown in the figure). The box body 110 includes an outer shell 120 and an inner tank 130 . The interior of the liner 130 defines a storage space 140. A foaming space 150 is defined between the inner tank 130 and the outer shell 120, and when the box body 110 is foamed and filled with polyurethane foaming reaction, the pressure of the foaming space 150 changes dynamically. The storage space 140 constitutes one or more storage compartments. The door body is arranged on the front side of the storage compartment for opening and closing the storage compartment. The number and structure of storage compartments can be configured according to requirements. For ex...

The invention provides a refrigerator, comprising a box body, the box body comprising: an outer shell; and an inner container, the interior of the inner container defines a storage space, and a foaming space is defined between the inner container and the outer shell ; When the box is filled with polyurethane foam, the pressure in the foam space changes dynamically. The refrigerator of the present invention includes a box body, the box body includes an outer shell and an inner container, the interior of the inner container defines a storage space, and a foaming space is defined between the inner container and the outer shell, when the box body is foamed and filled with polyurethane foaming reaction , The dynamic change of the pressure in the foaming space improves the insulation performance of the refrigerator, reduces the cost of the foaming material, shortens the curing time, reduces the number of surface air bubbles, and improves the surface crust.
Description
technical field [0001] The invention relates to the technical field of refrigeration and freezing devices, in particular to a refrigerator. Background technique [0002] Refrigerator foaming generally refers to rigid polyurethane foaming, and the foam is between the outer shell and the inner tank of the refrigerator. The performance of the foam and the production process determine the performance of the refrigerator. Existing refrigerators use constant pressure for foaming, which has the problems of poor thermal conductivity of the product, high cost of foaming materials, and long time. In addition, existing refrigerators have the problems of insufficient sealing technology and complex sealing operations when foaming. Contents of the invention [0003] SUMMARY OF THE INVENTION An object of the present invention is to provide a refrigerator with high thermal insulation performance and low cost of foaming materials. [0004] A further object of the present invention is to...
