[0022] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0023] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0024] An embodiment of the present invention provides a refrigerator, such as Figure 2 As shown, the refrigerator includes a box body 100, which is an approximately rectangular structure. The box body 100 includes two shells, an inner shell and an outer shell. The tops of the inner shell and the outer shell both have openings. The inner shell is arranged inside the outer shell. The interior of the inner shell forms a storage chamber, and a foam layer for insulation is filled between the inner shell and the outer shell; the door body 200 is arranged at the opening at the top of the box body 100, for opening or closing the storage chamber.

[0025] The door 200 is hinged to the box 100 via a hinge 300, so that the door 200 and the box 100 are rotatably connected. Figure 3 As shown, the hinge 300 includes a first hinge part 310 and a second hinge part 320. The first hinge part 310 and the second hinge part 320 are rotatably connected via a rotating shaft. The first hinge part 310 is fixed on the back of the outer shell of the box body 100, and the second hinge part 320 is fixed on the rear wall of the door body 200. The thickness of the first hinge part 310 is less than the thickness of the second hinge part 320. The first hinge part 310 is at least partially embedded in the back of the outer shell of the box body 100.

[0026] The refrigerator provided by the embodiment of the present invention has a door body 200 hingedly connected to the box body 100 by a hinge 300. The first hinge portion 310 on the hinge 300 is fixed to the back of the box body 100, and the second hinge portion 320 is fixed to the rear wall of the door body 200. The first hinge portion 310 and the second hinge portion 320 are rotatably connected to each other so that the door body 200 is hinged to the box body 100, and the thickness of the second hinge portion 320 is less than the thickness of the first hinge portion 310. Therefore, the first hinge portion 310 is partially embedded in the back of the box body 100. , and the second hinge part 320 itself is relatively thin, so that when the hinge 300 is installed on the refrigerator, the overall thickness is reduced, and then the width dimension of the refrigerator is reduced without reducing the volume of the refrigerator, so that the overall volume of the refrigerator is smaller. During transportation, the space occupied by the refrigerator can be reduced and the packing volume of the refrigerator can be increased. On the other hand, hiding the hinge 300 in the box body 100 can improve the appearance of the refrigerator and make the product more beautiful compared to the prior art in which the hinge 300 is more abruptly set on the back of the box body 100.

[0027] Since the hinge 300 is embedded in the back of the box 100, the hinge 300 needs to be fixed inside the box 100, that is, fixed between the outer shell and the inner shell of the box 100, and a foam layer is provided between the outer shell and the inner shell of the box 100. The foam layer material is generally soft. Fixing the hinge 300 in the middle of the foam layer will cause the hinge 300 to be not firmly fixed. If the hinge 300 is fixed on the inner shell, due to a certain distance between the outer shell and the inner shell, the hinge will be far away from the back of the box 100. When the second hinge part 320 of the hinge 300 is connected to the rear wall of the door body 200, the door body 200 and the box 100 will be misaligned with each other, resulting in the door body 200 being unable to completely close the storage chamber of the box 100, affecting the connection between the box 100 and the door body 200.

[0028] In an exemplary embodiment, Figure 3 、 Figure 4 As shown, a hinge mounting box 400 is embedded in the back of the box 100, and a mounting cavity (not shown in the figure) is formed in the hinge mounting box 400. The first hinge portion 310 is installed in the mounting cavity, and the upper end of the first hinge portion 310 extends out of the hinge mounting box 400 and is rotatably connected to the second hinge portion 320. By embedding a hinge mounting box 400 on the inner wall of the back of the outer shell of the box 100, the first hinge portion 310 of the hinge 300 is fixed in the mounting cavity of the hinge mounting box 400, so that the hinge 300 can be stably fixed to the box 100, and then the upper end of the first hinge portion 310 extends out of the mounting cavity and is rotatably connected to the second hinge portion 320. Finally, the second hinge portion 320 is fixed to the door body 200, so that the box 100 and the door body 200 form a stable hinge structure.

[0029] In an exemplary embodiment, during production, the hinge mounting box 400 can be first fixed to the inner wall of the outer shell, and the first hinge part 310 of the hinge 300 can be installed in the mounting cavity of the hinge mounting box 400, and then the inner shell can be installed in the outer shell, and a foam layer can be filled between the outer shell and the inner shell, and fixed. Finally, the second hinge part 320 is connected to the first hinge part 310 through a rotating shaft to realize the rotational connection between the first hinge part 310 and the second hinge part 320, and then the second hinge part 320 is fixed to the rear wall of the door body 200, so that the hinge 300 is embedded in the back of the outer shell of the box body 100, thereby reducing the width dimension of the refrigerator.

[0030] In order to facilitate the maintenance and replacement of the hinge 300, in an exemplary embodiment, as shown in FIG. Figure 3-Figure 5 As shown, a notch 111 is provided on the back shell 110 of the box body 100 at a position corresponding to the hinge installation box 400, and a mounting opening 430 is provided on the hinge installation box 400 opposite to the notch 111, and the first hinge portion 310 is installed into the installation cavity through the mounting opening 430. In the embodiment of the present invention, the notch 111 and the mounting opening 430 are correspondingly provided on the back shell 110 of the box body 100 and the hinge installation box 400, that is, a groove structure is formed on the back shell 110 of the box body 100, so that the box body 100 and the door body 200 can be installed first, and finally the first hinge portion 310 can be installed into the installation cavity of the hinge installation box 400 through the notch 111 and the mounting opening 430. When the hinge 300 is damaged and needs to be replaced, it can also be disassembled through the notch 111 and the mounting opening 430, thereby making the disassembly and assembly of the hinge 300 more convenient.

[0031] In an exemplary embodiment, a flange structure is provided at the edge of the mounting opening of the hinge mounting box 400, and the flange structure is parallel to the back of the box body 100. The hinge mounting box 400 is fixedly connected between the flange structure on the hinge mounting box 400 and the back shell 110 of the box body 100 by screws, thereby achieving the fixation of the hinge mounting box 400.

[0032] In an exemplary embodiment, the hinge mounting box 400 is stamped using a sheet metal process. Since metal material is used, the hinge mounting box 400 is more sturdy, and the overall strength of the hinge mounting box 400 fixed on the box body 100 is higher, thereby avoiding the occurrence of unstable installation of the hinge 300 due to damage to the hinge mounting box 400.

[0033] In another exemplary embodiment, the connection between the hinge mounting box 400 and the rear shell 110 of the box body 100 is as follows: Figure 3 and Figure 6As shown, the hinge mounting box 400 includes an outer box body 420 and an inner box body 410 disposed inside the outer box body 420. The outer box body 420 and the inner box body 410 are detachably connected. Both the outer box body 420 and the inner box body 410 are provided with mounting openings 430 corresponding to the notch 111. The first hinge portion 310 is installed into the inner box body 410 through the mounting opening 430 of the inner box body 410. Figure 9 As shown, a first flange 422 is formed at the edge of the mounting opening 430 of the outer box body 420. Figure 8 As shown, a second flange 412 is formed at the edge of the mounting opening 430 of the inner box body 410. Figure 7 As shown, the first flange 422 and the second flange 412 are respectively located on the inner and outer sides of the rear shell 110 of the box body 100, and clamp the rear shell 110 of the box body 100. This connection method divides the hinge installation box 400 into two parts, the inner box body 410 is arranged inside the outer box body 420, the first hinge part 310 is arranged inside the inner box body 410, and the edges of the installation opening 430 of the outer box body 420 and the inner box body 410 are respectively formed with the first flange 422 and the second flange 412, and the first flange 422 and the second flange 412 are respectively arranged on the inner and outer sides of the rear shell 110 of the box body 100, and clamp the rear shell 110 of the box body 100. The back shell 110, therefore, in this structure, when the first hinge part 310, the inner box body 410 and the outer box body 420 are fixed in sequence, the first flange 422 and the second flange 412 can clamp the back shell 110 of the box body 100, so that the hinge mounting box 400 is fixed on the back shell 110 of the box body 100, and this fixing method does not require adding screws or other fasteners on the back shell 110 of the box body 100, which is beneficial to the overall appearance of the box body 100.

[0034] In an exemplary embodiment, in the structure of the hinge mounting box 400, the outer box body 420 is made of metal material and is formed by sheet metal stamping, thereby increasing the strength of the hinge mounting box 400, and the inner box body 410 is made of plastic material and is formed by injection molding. Since the outer box body 420 already provides a higher structural strength, the use of plastic material for the inner box body 410 can reduce the overall cost of the hinge mounting box 400.

[0035] In an exemplary embodiment, through holes are provided on the first hinge part 310 and the inner box body 410, and threaded holes are provided on the outer box body 420, so that the screws are passed through the first hinge part 310 and the inner box body 410 in sequence from one side of the first hinge part 310, and then matched with the threaded holes on the outer box body 420. In the process of tightening the screws, the first flange 422 and the second flange 412 can be clamped to the back shell 110 of the box body 100, thereby realizing a fixed connection between the hinge mounting box 400 and the back shell 110 of the box body 100.

[0036] In order to prevent the inner box body 410 and the outer box body 420 from moving relative to each other or being misaligned when the inner box body 410 is installed in the outer box body 420, thereby affecting the fixation between the inner box body 410, the outer box body 420 and the first hinge part 310, in an exemplary embodiment, a pre-positioning structure is provided between the outer box body 420 and the inner box body 410. The pre-positioning structure is used to prevent the outer box body 420 and the inner box body 410 from moving relative to each other in a direction parallel to the back of the box body 100. The pre-positioning structure can prevent the inner box body 410 and the outer box body 420 from moving parallel to the back of the box body 100, so that the threaded holes on the outer box body 420 and the through holes on the inner box body 410 correspond to each other, making it easier to tighten the screws and making the installation of the hinge mounting box 400 more convenient.

[0037] In an exemplary embodiment, Figure 7 、 Figure 8 、 Figure 9 As shown, the pre-positioning structure includes a positioning column 411 provided on the inner box body 410 and a positioning hole 421 opened on the outer box body 420. The axis of the positioning column 411 is perpendicular to the back of the box body 100, and the positioning column 411 is inserted into the positioning hole 421. Through the positioning column 411 and the positioning hole 421, during installation, first insert the positioning column 411 into the positioning hole 421. Since the axis of the positioning column 411 is perpendicular to the back of the box body 100, it can prevent the inner box body 410 and the outer box body 420 from moving relative to each other in a direction parallel to the back of the box body 100, thereby determining the relative position between the inner box body 410 and the outer box body 420, and then install the hinge 300 in the inner box body 410 and fix it with screws. Pre-positioning is performed through the positioning column 411 and the positioning hole 421, so that the threaded hole on the outer box body 420 and the through hole on the inner box body 410 can be accurately positioned, so that the screw can smoothly pass through the hinge 300, the inner box body 410 and the outer box body 420 in turn. Through the positioning structure of the positioning post 411 and the positioning hole 421, precise positioning can be achieved by simply inserting the positioning post 411 into the positioning hole 421. Moreover, since the positioning post 411 is stuck in the positioning hole 421, there will be no relative movement between the two, making positioning more convenient.

[0038] Since the back plate is generally made of metal material, the notch 111 provided at the edge of the back shell 110 of the box body 100 is trimmed, and the trimming of the notch 111 is easy to scratch the user. Figure 6 、 Figure 10As shown, the edge of the notch 111 provided in this embodiment of the present invention is provided with a third flange 112, which is bent toward the interior of the housing 100. By bending the cut edge of the notch 111 and bending it toward the interior of the housing 100, the edge of the notch 111 seen from the outside is a smooth curved structure, thereby preventing the notch 111 from scratching the user.

[0039] In addition, when installing the hinge mounting box 400, the third flange 112 can form a positioning, that is, the mounting opening 430 of the outer mounting box is stuck on both sides of the third flange 112, making installation more convenient. Specifically, when installing the inner box body 410, the inner box body 410 is first placed on the notch 111. Due to the structure of the third flange 112, the outer wall of the inner box body 410 and the third flange 112 are in surface-to-surface contact, making the structure more stable. Then, the outer box body 420 is placed on the inner box body 410, and the inner wall of the inner box body 410 and the third flange 112 are also in surface-to-surface contact, that is, the third flange 112 is located between the inner box body 410 and the outer box body 420, thereby further positioning the inner box body 410 and the outer box body 420. Finally, the first hinge portion 310 is fixedly connected to the inner box body 410 and the outer box body 420.

[0040] In an exemplary embodiment, in order to prevent the foam layer on the inner side of the rear shell 110 of the box body 100 from overflowing, as shown in FIG. Figure 6 、 Figure 10 As shown, fourth flanges 113 are provided at both the upper and lower edges of the back shell 110 of the box body 100. The fourth flanges 113 are bent toward the interior of the box body 100 and are respectively fixedly connected to the top and bottom surfaces of the box body 100. By providing the fourth flanges 113 at both the upper and lower edges of the back shell 110 of the box body 100, the contact area between the back shell 110 of the box body 100 and the top and bottom surfaces of the box body 100 is increased, thereby reducing the gaps between the back shell 110 of the box body 100 and the top and bottom surfaces of the box body 100, thereby effectively preventing overflow of the foam material.

[0041] In an exemplary embodiment, in order to further improve the overall appearance of the refrigerator, Figure 2 、 Figure 3As shown, the first hinge portion 310 and the second hinge portion 320 provided in this embodiment of the present invention are each covered with a hinge cover 330, and the hinge cover 330 is detachably connected to the hinge 300. By providing the hinge cover 330 on both the first hinge portion 310 and the second hinge portion 320, the hinge 300 is concealed within the hinge cover 330, so that the hinge 300 structure is not directly visible from the outside, which improves the overall aesthetics of the refrigerator. In addition, the hinge cover 330 is detachably connected to the hinge 300, so that if the hinge 300 is damaged, the hinge cover 330 can be directly removed and the hinge 300 can be repaired or replaced, making disassembly and assembly convenient.

[0042] Since refrigerators are generally long in length, in order to achieve a more balanced and stable hinged connection between the door 200 and the housing 100, in an exemplary embodiment, at least two hinges 300 are provided. If only one hinge 300 is provided in the middle of the refrigerator's length, it is difficult to provide a balanced connection structure at a single connection point during use. Moreover, the door 200 is heavy, and a single hinge 300 is easily damaged by the weight. Therefore, at least two hinges 300 are evenly distributed throughout the refrigerator, so that at least two hinges 300 share the weight of the door 200, making the connection structure more balanced and improving the connection strength between the door 200 and the housing 100.

[0043] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0044] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
