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 arranged adjacent to the embedded 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 further includes a housing body 21 assembled with each other, 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, and a second wall 222 formed by bending the first wall 221 toward the liner 1 (i.e., bending and extending in a vertical direction), the first wall 221 of the reinforcing beam 22 is fixed to a top wall of the housing 2, the second wall 222 is fixed to a portion of the side wall of the housing 2 bent in a transverse direction, and the reinforcing beam 22 is integrally fixed to the housing 2 and disposed at a foremost end of the housing 2, thereby increasing the integrity of the housing 2.

In the present embodiment, the mounting notch 223 is provided in the first wall 221 and the second wall 222 of the reinforcement beam 22 and penetrates in the up-down direction. I.e. it can be understood that: the mounting cutouts 223 are formed recessed rearward from the front ends of the first wall 221 and the second wall 222.

Because the embedded box 3 is arranged between the shell 2 and the liner 1, the stiffening beam 22 is arranged independently, so that the shell body 21 and the liner 1 are conveniently connected, the structural strength of the embedded 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.

In this embodiment, the pre-buried box 3 is disposed between the top wall of the housing 3 and the liner 1 and is located at the front side of the foaming cavity 5. 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 pre-buried box 3 to protrude 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 pre-buried 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 embedded box 3 is arranged in the foaming cavity 5 between the side wall and the liner 1, only part of the embedded box 3 can be arranged to protrude out of the side wall of the shell 2, and then a containing structure matched with the protruding structure is arranged in the cabinet. When the embedded box 3 is arranged in the foaming cavity 5 between the refrigerating chamber and the freezing chamber, the heat insulation performance of the embedded box 3 is increased so as to reduce the influence of the low temperature of the freezing chamber on the embedded box.

In this embodiment, the adjacent shell 2 inner wall setting of pre-buried box 3, promptly pre-buried box 3 paste and apply in shell 2 roof setting, so, not only can increase the distance between pre-buried 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 pre-buried box 3 has a top wall, a bottom wall, two side walls and a rear wall connected between the top wall and the bottom wall, and an opening 31 formed on one side of the rear wall opposite to the top wall and the bottom wall, the opening 31 is communicated with the mounting notch 223, the outer wall surface of the pre-buried box 3, which is disposed against the inner wall of the housing, is the top wall of the pre-buried box 3, and the main control board 4 is disposed parallel to the top wall and the bottom wall.

The mounting seat 7 is further fixed to the pre-buried box 3 through another portion, specifically, the front wall of the mounting seat 7 is further provided with a fixing portion 723 protruding outwards, a fixing hole 315 matched with the fixing portion 723 is formed in the rear inner wall of the second accommodating cavity 39, and the fixing portion 723 and the fixing hole 315 are fixed through a screw.

In this embodiment, one end of the second accommodating cavity 39 is aligned with the first accommodating cavity 38, so that the rear inner wall of the second accommodating cavity 39 is located on only one side in the transverse direction, and the rear inner wall of the second accommodating cavity 39 further has a recess recessed backward to accommodate the fixing portion 723, so that the front end surface of the fixing portion 723 is flush with the rear inner wall, and smooth installation of the display control assembly 6 is ensured.

Meanwhile, the via hole 36 of the pre-buried box 3 is disposed at the rear side of the second accommodating cavity 39 which is longer than the first accommodating cavity 38, so that the position of the via hole 72 is located at the middle position of the width of the second accommodating cavity 39 in the transverse direction, thereby being more convenient for connecting the wire bundles with the display control circuit board 62, that is, the length difference between the wire bundles connected with the display control circuit board 62 is smaller, the arrangement and arrangement are easier, and the selection of the display control circuit board 62 is wider.

The fixing portion 723 located at the other side in the transverse direction is matched with the protruding portion 316 protruding from the pre-buried box 3, and the fixing hole 315 is also formed in the protruding portion 316, so that the fixing effect of the mounting seat 7 can be effectively ensured by the first elastic portion 79, the second elastic portion 721, the fixing portion 723 and the fixing hole 315.

The refrigerator further comprises appearance pieces 8 arranged on the left side and the right side of the display control assembly 6, and the appearance pieces 8 are fixed on the reinforcing beams 22, so that the reinforcing beams 22 are prevented from being exposed, and the attractiveness is improved. And the sizes of the appearance pieces 8 on the left side and the right side are inconsistent, wherein the appearance piece 8 on the hinge side of the door body is smaller.

As shown in fig. 11 and 12, a second embodiment of the refrigerator of the present invention is different from the first embodiment in that: the display control assembly 6 comprises a display control bracket 61 integrally formed at the front side of the mounting seat 7, a display control circuit board 62 fixed at the rear side of the display control bracket 61, and a display control panel 63 covered at the front side of the display control bracket 61.

That is, the front wall of the mounting seat 7 and the display control bracket 61 are of the same structure, so that not only is the main control board 4 convenient to fix, but also the display control circuit board 62 is convenient to fix, more materials are saved, and the cost is effectively reduced. In this embodiment, the display control circuit board 62 is disposed between the display control support 61 and the main control board 4 and is located in the inner mounting cavity 71, so that the display circuit board can be directly connected with the main control board 4 in the inner mounting cavity 71, the distance between the display circuit board and the main control board is shorter, and the wire harness for connecting the display control circuit board and the main control board does not need to pass through the mounting seat 7 forward, so that the difficulty in arranging the wire harness is reduced.

In addition, since the display control panel 63 and the display control bracket 61 are also fixed together, when the display control panel 63 and the embedded box 3 are disassembled for maintenance, the fixing structure between the display control panel 63 and the embedded box 3 can be directly released, and then the display control panel 63 can be directly pulled out. Therefore, the main control board 4 can be taken out in one step, and the maintenance steps are greatly simplified. It is needless to say that the mounting base 7 and the pre-buried box 3 are fixed only by the above-mentioned positioning structure, and the fixing portion 723 and the fixing hole 315 of the mounting base 7 are not fixed by screws, or the fixing portion 723 and the fixing hole 315 are not necessarily provided.

In summary, the refrigerator shell 2 of the present invention has the mounting notch 223 for mounting the embedded box 3, and the fastening hole 23 near the mounting notch 223, the embedded box 3 has the outer wall surface disposed against the inner wall of the shell 2, and the fastening structure 34 protruding from the outer wall surface, and the fastening structure 34 passes through the fastening hole 23 to fasten and fix with the shell 2. Therefore, when the embedded box 3 is assembled and fixed, the embedded box 3 can be pre-fixed on the shell 2, and then the embedded box 3 and the shell 2 are further fixed through the screws, so that the assembly efficiency of the embedded box 3 is greatly improved.

The above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention.
