The present invention will be described in detail below with reference to embodiments shown in the drawings. But in the embodiment and

without limiting the invention, variations in structure, method, or function that would occur to one of ordinary skill in the art based on this embodiment are included within the scope of the invention.

Referring to fig. 1 to 11, an embodiment of a refrigerator according to the present invention is shown, the refrigerator includes a refrigerator body and a door body for opening or closing the refrigerator body, the refrigerator body includes a liner 1, a housing 2 located outside the liner 1, the refrigerator further includes a mounting box 3 disposed between the liner 1 and the housing 2, and a main control board 4 disposed in the mounting box 3, the mounting box 3 has an opening 31 penetrating outwards, and the refrigerator further includes a display control assembly 6 disposed at the opening 31 in a matching manner and electrically connected to the main control board 4.

Specifically, as shown in fig. 1 to 3, in this embodiment, the refrigerator is an embedded refrigerator, and is mainly disposed in a cabinet, and may be a conventional refrigerator. The refrigerator is characterized in that a foaming cavity 5 is formed between the shell 2 and the liner 1, and the refrigerator is further provided with an insulation layer which is arranged between the shell 2 and the liner 1 and is adjacent to the installation box 3, wherein the insulation layer can be a foaming layer formed in the foaming cavity 5 in a foaming mode or can be of a vacuum heat insulation design.

In this embodiment, the housing 2 has a top wall and two side walls, and the mounting box 3 is disposed between the top wall and the liner 1. On the one hand, because the area of roof is less than the area of lateral wall relatively, with the foaming chamber 5 thickening between roof and the inner bag 1 easily to avoid mounting box 3 to outstanding in shell 2, and the foaming chamber 5 between thickening roof and the inner bag 1 is lower for the foaming chamber 5 between thickening lateral wall and the inner bag 1, the cost.

On the other hand, the storage compartment on the upper side of the general refrigerator is a refrigerating compartment, and the storage temperature is relatively high compared with that of the freezing compartment, so that the temperature of the refrigerating compartment is not easy to influence the operation of the main control board 4. Meanwhile, the main control board 4 arranged at the position is unnecessary for maintenance personnel to bend down, so that maintenance difficulty is reduced.

Of course, in other embodiments, the mounting box 3 may also be disposed in the foaming chamber 5 between the side wall and the liner 1, and in the foaming chamber 5 between the refrigerating chamber and the freezing chamber. When the mounting box 3 is disposed in the foaming chamber 5 between the side wall and the inner container 1, only a portion of the mounting box 3 may protrude from the side wall of the outer case 2, and then a receiving structure is provided in the cabinet to be matched with the protruding structure. When the mounting box 3 is disposed in the foaming chamber 5 between the refrigerating chamber and the freezing chamber, the insulation performance of the mounting box 3 should be increased to reduce the influence of the freezing chamber low temperature thereon.

In this embodiment, the installation box 3 is adjacent shell 2 inner wall setting, namely installation box 3 subsides apply in shell 2 roof setting, so, not only can increase the distance between installation box 3 bottom and the inner bag 1 to increase the heat preservation thickness between the two, and then reduce the indoor temperature of storing room and to the influence of main control board 4, the produced heat of main control board 4 during operation also can go out by means of the shell 2 conduction of metal material in addition, strengthens the radiating effect. Meanwhile, under the condition of enough heat preservation effect, the distance between the top wall of the shell 2 and the liner 1 can be minimized, namely the foaming cavity 5 is thinnest, and the volume of the refrigerator is reduced.

In this embodiment, the housing 2 includes a housing body 21 and a reinforcing beam 22 disposed on a front side of the housing body 21, the reinforcing beam 22 has a first wall 221 extending in a front-rear direction, a second wall 222 formed by bending the first wall 221 toward the liner 1 (i.e., extending by bending in an up-down direction), and the opening 31 of the mounting box 3 penetrates the second wall 222. 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 portion of the side wall of the housing 2 that is bent in the transverse direction, and the reinforcing beam 22 is integrally fixed to the interior of the housing 2 and is disposed at the forefront end of the housing 2, thereby increasing the integrity of the housing 2.

Because the mounting box 3 is arranged between the top wall of the shell 2 and the liner 1, the reinforcing beam 22 is arranged independently, so that the shell body 21 and the liner 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 housing body 21 and the reinforcing beam 22 may be integrally formed.

A notch 223 that is opened forward is provided at a position of the housing 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 reinforcement beam 22 and penetrates in the up-down direction. I.e. it can be understood that: the notch 223 is formed to be recessed rearward from the front end of the first wall 221. And, 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 in cooperation with the outer wall of the mounting box 3. And the position of the opening 31 of the mounting box 3 penetrating the second wall 222 communicates with the notch 223 so that the upper front end of the mounting box 3 is exposed to the outside.

Therefore, when repairing, the repairing personnel can not touch the reinforcing beam 22, even if the opening 31 of the mounting box 3 is not very large, the repairing personnel can only touch the plastic structure of the mounting box 3, thereby not being scratched by the metal structure of the reinforcing beam 22 and reducing the injury risk of the repairing personnel. Of course, in other embodiments, the mounting box 3 may not protrude into the notch 223, that is, the outer wall of the mounting box 3 is attached to the inner wall surface of the first wall 221.

As shown in fig. 4 to 7, the mounting box 3 includes an upper cover 32 and a lower cover 33 assembled to each other up and down, and thus, the molding assembly is simpler. Of course, in other embodiments, the mounting box 3 may be integrally formed.

The retaining structure 34 includes a first retaining portion 341 fixed to the mating structure 23, and a second retaining portion 342 located on the front side of the first retaining portion 341 and fixed to the front end wall of the housing 2 (i.e., the front end wall of the first wall 221 of the reinforcement beam 22). And the pre-positioning structure comprises a plurality of through holes, a first clamping part 341 and a second clamping part 342 which are arranged along the transverse direction.

The first clamping portion 341 and the second clamping portion 342 are disposed on the upper cover 32, and clamping cavities of the first clamping portion 341 and the second clamping portion 342 are disposed opposite to each other. When the fixing is performed, the first clamping portion 341 is first placed in the through hole from bottom to top and moved forward, and then the mounting box 3 is lifted up and pushed backward, so that the second clamping portion 342 is clamped to the front end wall of the housing 2 (i.e., the front end wall of the reinforcing beam 22).

And through setting up first clamping portion 341 and second clamping portion 342, on the one hand, can increase the bearing capacity of clamping structure 34, reduce the risk of first clamping portion 341 and second clamping portion 342 impaired. On the other hand, the screw fixing mode is avoided, the screw penetrates through the upper cover 32 to hurt the main control board 4 in the installation box 3, and meanwhile, maintenance personnel can be prevented from being scratched by the screw.
