In this embodiment, the control component is disposed in the box, and it should be noted that the control component is disposed in the box and located between the outer shell 2 and the inner container 1, and the display and control component 6 is exposed from the box, but the control component may also be disposed in the door, and then the display and control component 6 is exposed from the door. The refrigerator is an embedded refrigerator and is mainly arranged in a cabinet, and can be a traditional refrigerator. Moreover, the control assembly can also be applied to refrigeration equipment, such as a refrigerator, a wine cabinet and even other technical fields with devices of the control assembly.

Specifically, as shown in fig. 1 to 3, which are the first embodiment of the present invention, in this embodiment, a foaming cavity 5 is formed between the outer shell 2 and the inner container 1, the refrigerator further has a heat insulating layer disposed between the outer shell 2 and the inner container 1 and adjacent to the mounting box 3, and the heat insulating layer may be a foaming layer formed in the foaming cavity 5 by foaming, or may be designed to be vacuum heat insulating.

In the present embodiment, the housing 2 includes a housing body 21 assembled with each other, and a reinforcing beam 22 disposed at the front side of the housing body 21, the reinforcing beam 22 includes a first wall 221 extending in the front-rear direction, and a second wall 222 formed by bending from the first wall 221 toward the inner container 1 (i.e., bending and extending in the up-down direction), and the opening 31 of the mounting box 3 penetrates the second wall 222 forward. The first wall 221 of the reinforcing beam 22 is fixed to the top wall of the housing 2, the second wall 222 is fixed to the bent portion of the side wall of the housing 2 in the transverse direction, and the reinforcing beam 22 is integrally fixed to the inside of the housing 2 and disposed at the foremost end of the housing 2, thereby increasing the integrity of the housing 2.

Because the mounting box 3 is arranged between the shell 2 and the inner container 1, the reinforcing beam 22 is independently arranged, so that the shell body 21 and the inner container 1 are conveniently connected, the structural strength of the mounting box 3 is improved, the process is simpler, and the production efficiency is higher. Of course, in other embodiments, the shell body 21 and the reinforcing beam 22 may be integrally formed.

A notch 223 opened forward is provided at a position of the case 2 adjacent to the opening 31 of the mounting box 3, and in this embodiment, the notch 223 is provided on the first wall 221 of the reinforcing beam 22 and penetrates in the vertical direction. I.e. can be understood as: the notch 223 is formed to be recessed rearward from the front end of the first wall 221. Moreover, the part of the mounting box 3 corresponding to the notch 223 protrudes into the notch 223 and covers the inner wall of the notch 223. I.e. the inner wall of the notch 223 is arranged to cooperate with the outer wall of the mounting box 3. And the opening 31 of the mounting box 3 communicates with the notch 223 through the position of the second wall 222 so that the upper front end of the mounting box 3 is exposed to the outside.
