A foaming cavity 5 is formed between the outer shell 2 and the inner liner 1, and the refrigerator also has a thermal insulation layer arranged between the outer shell 2 and the inner liner 1 and adjacent to the embedded box 3, and the aforementioned thermal insulation layer can be foamed. The foam layer formed in the foam cavity 5 may also be designed for vacuum heat insulation.

In this embodiment, the casing 2 further includes a casing body 21 assembled with each other, and a reinforcing beam 22 disposed on the front side of the casing body 21. The reinforcing beam 22 has a first wall 221 extending in the front-rear direction, a The first wall 221 is bent toward the second wall 222 formed by the direction of the inner pot 1 (ie, it is bent and extended in the up-down direction). The part of the side wall of the casing 2 that is bent in the lateral direction is fixed, and the reinforcing beam 22 is integrally fixed inside the casing 2 and is disposed at the foremost end of the casing 2 , thereby increasing the integrity of the casing 2 .

In this embodiment, the installation cutout 223 is disposed on the first wall 221 and the second wall 222 of the reinforcing beam 22 and is disposed along the up-down direction. That is to say, it can be understood that the installation cutout 223 is formed by being recessed backward from the front ends of the first wall 221 and the second wall 222 .

Since the pre-embedded box 3 of the present invention is arranged between the outer shell 2 and the inner container 1 , by separately disposing the reinforcing beams 22 , it is not only convenient to connect the outer shell body 21 and the inner container 1 , but also improves the structural strength of the pre-embedded box 3 . , and the process is simpler and the production efficiency is higher. Of course, in other embodiments, the shell body 21 and the reinforcing beam 22 can also be integrally formed.
