All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
Reference is made to FIGS. 1 to 12 which show embodiments of a refrigerator according to the present invention, the refrigerator comprises a refrigerator body and a door body located on a front side of the refrigerator body to open or close the refrigerator body, the refrigerator body comprises an inner container 1 and a housing 2 located on an outer side of the inner container, the refrigerator further comprises a pre-embedded box 3 provided between the inner container 1 and the housing 2, and a main control board 4 provided in the pre-embedded box 3, the housing 2 has a mounting notch 223 for mounting the pre-embedded box 3 and a fastening hole 23 provided close to the mounting notch 223, the pre-embedded box 3 has an outer wall surface attached to an inner wall of the housing 2 and a fastening structure 34 formed by protruding from the outer wall surface, and the fastening structure 34 penetrates through the fastening hole 23 to be fixedly buckled to the housing 2.
Specifically, as shown in FIGS. 1 to 3 which show a first embodiment of the present invention, in the present embodiment, the refrigerator is configured as an embedded refrigerator and mainly provided in a cupboard, and certainly, the refrigerator can be configured as a traditional refrigerator. A foaming cavity 5 is formed between the housing 2 and the inner container 1, the refrigerator further has a heat insulating layer provided between the housing 2 and the inner container 1 adjacent to the mounting box 3, and the heat insulating layer can be formed in the foaming cavity 5 by foaming or have a vacuum heat insulating design.
In the present embodiment, the housing 2 comprises an assembled housing body 21, and a reinforcing beam 22 provided 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 from the first wall 221 towards the inner container 1 (that is, bent and extending in an up-down direction), and the opening 31 of the mounting box 3 penetrates through the second wall 222 forwards. 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 part of a side wall of the housing 2 bent in a transverse direction, and the whole reinforcing beam 22 is fixed inside the housing 2 and provided at a foremost end of the housing 2, thereby increasing integrity of the housing 2.
In the present embodiment, the mounting notch 223 is provided on the first wall 221 and the second wall 222 of the reinforcing beam 22 and is through in the up-down direction. That is, it can be understood that the mounting notch 223 is formed by recessing a front end of the first wall 221 and the second wall 222 backwards.
Since the pre-embedded box 3 in the present invention is provided between the housing 2 and the inner container 1, by independently providing a reinforcing beam 22, a housing body 21 and the inner container 1 can be conveniently connected, structural strength of the pre-embedded box 3 is improved, a process is simpler, and a production efficiency is higher. Certainly, in other embodiments, the housing body 21 and the reinforcing beam 22 can be integrally formed.
In the present embodiment, the pre-embedded box 3 is provided between a top wall of the housing 2 and the inner container 1 and located on a front side of a foaming cavity 5. On the one hand, since an area of the top wall is less than an area of a side wall, the foaming cavity 5 between the top wall and the inner container 1 can be easily thickened to prevent the pre-embedded box 3 from protruding from the housing 2, and the foaming cavity 5 between the thickened top wall and the inner container 1 has a lower cost compared with the foaming cavity 5 between the thickened side wall and the inner container 1.
On the other hand, generally, a storage compartment on an upper side of the refrigerator is configured as a refrigerating chamber, and has a relatively higher storage temperature than a freezing chamber, such that the temperature of the refrigerating chamber is not prone to influence work of the main control board 4. Meanwhile, with the main control board 4 provided at this position, a repair person is not required to bend down for work, thus reducing repair difficulty.
Certainly, in other embodiments, the pre-embedded box 3 can be provided in the foaming cavity 5 between the side wall and the inner container 1, or the foaming cavity 5 between the refrigerating chamber and the freezing chamber. When the pre-embedded box 3 is provided in the foaming cavity 5 between the side wall and the inner container 1, only part of the pre-embedded box 3 can be provided to protrude from the side wall of the housing 2, and then, the cupboard is provided with an accommodating structure fitted with the protruding structure. When the pre-embedded box 3 is provided in the foaming cavity 5 between the refrigerating chamber and the freezing chamber, a heat insulating performance of the pre-embedded box 3 should be increased to reduce an influence of a low temperature of the freezing chamber thereon.
In the present embodiment, the mounting box 3 is provided adjacent to the inner wall of the housing 2; that is, the mounting box 3 is attached to the top wall of the housing 2, such that a distance between a bottom of the mounting box 3 and the inner container 1 can be increased, thereby increasing a thickness of the heat insulating layer therebetween, and then reducing the influence of the temperature in the storage compartment on the main control board; heat generated when the main control board 4 works can be conducted out through the housing 2 made of metal, thus improving a heat dissipation effect. Meanwhile, under a condition of a sufficient heat preservation effect, the distance between the top wall of the housing 2 and the inner container 1 can be minimized; that is, the foaming cavity 5 is thinnest, and a size of the refrigerator is reduced.
In the present embodiment, the pre-embedded 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 in a side between the top wall and the bottom wall opposite to the rear wall, the opening 31 is communicated with the mounting notch 223, the outer wall surface of the pre-embedded box 3 attached to the inner wall of the housing is configured as the top wall of the pre-embedded box 3, and the main control board 4 is parallel to the top wall and the bottom wall.
A part of the pre-embedded box 3 corresponding to the upper mounting notch 223 protrudes into the upper mounting notch 223 and covers an inner wall of the upper mounting notch 223. That is, the inner wall of the upper mounting notch 223 is provided to be fitted with an outer wall of the pre-embedded box 3. A position where the opening 31 of the pre-embedded box 3 penetrates through a second wall 222 is communicated with the front mounting notch 223, such that an upper front end of the pre-embedded box 3 is exposed outside.
Therefore, during repair, the repair person cannot touch the reinforcing beam 22, and even when the opening 31 of the pre-embedded box 3 is not quite large, the repair person can only touch a plastic structure of the pre-embedded box 3, such that the repair person cannot be scratched by a metal structure of the reinforcing beam 22, thus reducing an injury risk of the repair person. Certainly, in other embodiments, the pre-embedded box 3 may not protrude into the mounting notch 223; that is, the outer wall of the pre-embedded box 3 is provided to be attached to an inner wall surface of a first wall 221.
As shown in FIGS. 4 to 7, the pre-embedded box 3 comprises a top cover 32 and a base 33 which are assembled to each other up and down, such that forming and assembly are simpler; the top wall and the bottom wall are formed on the top cover 32 and the base 33 respectively.

The buckling portion 342 has a greater extension length than the extending portion 341, and an inclined surface extending obliquely towards an interior of the first buckling cavity 343 is formed at an end of the buckling portion 342 close to the mounting notch 223. With the above-mentioned structure, the pre-embedded box 3 and the housing 2 are pre-fixed, the greater extension length of the buckling portion 342 can guarantee a good fixing effect, and the inclined surface can ensure that the top wall of the housing 2 smoothly enters the first buckling cavity 343.
In the present embodiment, in order to improve the pre-fixing effect of the pre-embedded box 3 and the housing 2, the pre-embedded box 3 further has an abutting structure 30 protruding from the outer wall surface to abut against an edge of the mounting notch 223 of the housing 2, the abutting structure 30 and the fastening structure 34 are spaced apart in a front-rear direction, and the fastening structure 34 and the abutting structure 30 are staggered in a width direction of the pre-embedded box 3, such that the above structure is conveniently formed in a limited space of the pre-embedded box 3.

The pre-fixing effect can be further enhanced by fitting the abutting structure 30 with the fastening structure 34, and the fitting between the abutting structure 30 and the fastening structure 34 can reduce a risk of damage to the fastening structure 34 and/or the abutting structure 30.
With the above structure, the pre-embedded box 3 and the housing 2 can be pre-fixed, a screw fixing mode is avoided, the screws penetrate through the top cover 32 to damage the main control board 4 in the pre-embedded box 3, and meanwhile, the repair person can be prevented from being scratched by the screws. After prepositioning, hole positions between the pre-embedded box 3 and the housing 2 are aligned, and then, fixation is further performed using the screws, such that the pre-embedded box 3 is not required to be held with the hand during fixation by the screws, thus improving an assembly efficiency.
In the present embodiment, the mounting box 3 has supporting legs 35 protruding downwards from a lower surface of the lower cover 33 to be supported on the inner container 1, and the supporting legs 35 can assist the prepositioning structure, improve a prepositioning effect, and meanwhile reduce a risk of damage to the clamping structure 34.
