Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a refrigerator and its hinge structure. Background Technology

[0002] In existing technology, household refrigerators typically employ a multi-layered door structure to achieve better sealing and ease of use. Common refrigerator door structures include three sets of hinges: upper, middle, and lower, each used to support and guide the opening and closing of different door sections.

[0003] The middle hinge is a key component connecting the upper and lower doors. Its main function is to ensure that the upper and lower doors remain synchronized during opening and closing and to maintain a stable connection between them. However, because traditional middle hinges are shared by both the upper and lower doors and are a fixed connection, they lack flexibility and operability. In actual use, when users or maintenance personnel need to repair, replace, or clean the lower door, they often have to disassemble the upper door first. This not only increases the difficulty of repairs and reduces maintenance efficiency, but also causes inconvenience to users. Furthermore, during repairs, the door is prone to detachment or damage due to misoperation, affecting the overall lifespan of the refrigerator and the user experience. Utility Model Content

[0004] To address the technical problems of lack of flexibility and operability in existing technologies, and the inability to disassemble the door body independently, this utility model provides a refrigerator and its hinge structure.

[0005] The present invention adopts the following technical solution.

[0006] A hinge structure in a refrigerator, comprising:

[0007] The first hinge assembly is connected to the refrigerator body and the upper door.

[0008] The second hinge assembly is detachably connected to the first hinge assembly and connected to the lower door body.

[0009] Preferably, the first hinge assembly has a first screw hole and a third screw hole at both ends, the first hinge assembly has a first screw that passes through the first screw hole and is threaded to the refrigerator body, and the second hinge assembly has a third screw that passes through the third screw hole and is threaded to the refrigerator body.

[0010] Preferably, the first hinge assembly has a second screw hole in the middle, the second hinge assembly has a fourth screw hole corresponding to the second screw hole in the middle, and the second hinge assembly has a second screw that passes through the fourth screw hole and the second screw hole and is threadedly connected to the refrigerator body.

[0011] Preferably, the first hinge assembly is provided with a first hinge shaft that is connected to the upper door body.

[0012] Preferably, the second hinge assembly is provided with a second hinge shaft that is connected to the lower door body.

[0013] Preferably, the first hinge assembly is provided with a first torsion buckle structure, and the second hinge assembly is provided with a second torsion buckle structure that is torsionally engaged with the first torsion buckle structure.

[0014] Preferably, there is a gap between the second hinge assembly and the lower door body.

[0015] Preferably, the first hinge assembly has a splicing surface that matches the second hinge assembly, and the splicing surface is an arc surface.

[0016] Preferably, the second hinge assembly is provided with a handle.

[0017] The second aspect of this utility model provides a refrigerator, including the hinge structure in the refrigerator provided in the first aspect.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] By dividing the traditional refrigerator hinge into two detachable hinge components, the system offers flexibility and operability. When the lower door needs to be removed separately, the second hinge component can be directly detached from the first hinge component to release the lower door from its fixation. This allows the lower door to be removed without removing the upper door, avoiding the operational complexity caused by having to remove the upper door first.

[0020] In addition, by setting the first screw and the third screw, the installation and disassembly of the first hinge assembly and the refrigerator body are facilitated, thereby improving the ease of installation and disassembly.

[0021] By setting a second screw, the installation and disassembly of the second hinge assembly and the first hinge assembly can be facilitated, improving the convenience of installation and disassembly. The first hinge assembly and the second hinge assembly are fixed in the horizontal direction, improving the fixing effect and making it easy to release the fixation.

[0022] By setting a first hinge axis, the upper door can be rotated easily; by setting a second hinge axis, the lower door can be rotated easily, thus improving the refrigerator's performance.

[0023] By setting a first torsion buckle structure and a second torsion buckle structure that are torsionally connected, the first middle hinge assembly and the second middle hinge assembly are fixed in the vertical direction, thereby improving the fixing effect. There is a gap between the second middle hinge assembly and the lower door body, which makes it easy to release the fixation.

[0024] By setting the splicing surface, interference is avoided when the first hinge component and the second hinge component twist and assemble or disassemble, thus ensuring the effectiveness of use.

[0025] By setting a latch, it is easy to engage the second hinge assembly to rotate, thereby facilitating the release of the fixation between the first hinge assembly and the second hinge assembly. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The embodiments described in this application are merely some embodiments of this utility model, and not all embodiments. Based on the spirit of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention.

[0035] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0036] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0037] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0039] like Figure 1-3 As shown, Embodiment 1 of this utility model provides a hinge structure for a refrigerator, which is a composite hinge structure. The traditional refrigerator hinge is divided into two parts: a first hinge assembly 01 and a second hinge assembly 02. This modularizes the traditional refrigerator hinge. When removing the door, only the second screw 04 needs to be removed, and the second hinge assembly 02 can be rotated and moved to remove the door without disassembling the upper door. When removing the entire door, due to the composite hinge structure, the first hinge assembly 01 and the second hinge assembly 02 can be removed simultaneously, allowing for simultaneous removal of both the upper and lower doors. This operation requires removing two fewer screws than with a traditional refrigerator hinge, significantly saving operator time and reducing operational complexity. It also greatly reduces the workload for both R&D and maintenance personnel, improving work efficiency, refrigerator repair and maintenance efficiency, and reducing labor costs. The overall structure is compact, does not affect the original door's opening and closing function and sealing performance, and is compatible with various refrigerator door structures. It has wide applicability and promotional value, allowing multiple people to disassemble the door simultaneously. The hinge structure includes:

[0040] The first hinge assembly 01 is connected to the refrigerator body and the upper door.

[0041] The second hinge assembly 02 is detachably connected to the first hinge assembly 01 and connected to the lower door body.

[0042] The first hinge assembly 01 and the second hinge assembly 02 are detachably connected, providing flexibility and operability. When it is necessary to remove the lower door body separately, the second hinge assembly 02 can be directly removed from the first hinge assembly 01 to release the fixation of the lower door body.

[0043] Preferably, but not restrictively, the first hinge assembly 01 has a first screw hole and a third screw hole at both ends, the first hinge assembly 01 has a first screw 03 that passes through the first screw hole and is threaded to the refrigerator body, and the second hinge assembly 02 has a third screw 05 that passes through the third screw hole and is threaded to the refrigerator body.

[0044] This structure can be firmly fixed to the refrigerator body.

[0045] Preferably, but not restrictively, the first hinge assembly 01 has a second screw hole 013 in the middle, the second hinge assembly 02 has a fourth screw hole 014 corresponding to the second screw hole 013 in the middle, and the second hinge assembly 02 has a second screw 04 that passes through the fourth screw hole 014 and the second screw hole 013 and is threadedly connected to the refrigerator body.

[0046] The first hinge assembly 01 and the second hinge assembly 02 are fixed in the horizontal direction.

[0047] Preferably, but not restrictively, the first hinge assembly 01 is provided with a first hinge shaft 017 connected to the upper door body.

[0048] It facilitates the rotation of the upper door body.

[0049] Preferably, but not restrictively, the second hinge assembly 02 is provided with a second hinge shaft that is connected to the lower door body.

[0050] To facilitate the rotation of the lower door.

[0051] Preferably, but not restrictively, the first hinge assembly 01 is provided with a first torsion buckle structure 011, and the second hinge assembly 02 is provided with a second torsion buckle structure 012 that is torsionally engaged with the first torsion buckle structure 011.

[0052] The first hinge assembly 01 and the second hinge assembly 02 are fixed in the vertical direction.

[0053] Further preferred, but not limiting, is that the second hinge assembly 02 has a gap with the lower door body.

[0054] This facilitates downward movement of the second hinge assembly 02 relative to the first hinge assembly 01, so as to detach the second hinge assembly 02 from the first hinge assembly 01.

[0055] like Figure 5 As shown, preferably but not limitingly, the first hinge assembly 01 is provided with a splicing surface 015 that matches the second hinge assembly 02, and the splicing surface 015 is an arc surface.

[0056] To avoid interference when the first hinge assembly 01 and the second hinge assembly 02 are twisted together or disassembled.

[0057] like Figure 6 As shown, preferably but not limitingly, a handle 016 is provided on the second hinge assembly 02.

[0058] The second hinge assembly 02 can be easily engaged by the handle 016 to allow it to rotate horizontally relative to the first hinge assembly 01.

[0059] Embodiment 2 of this utility model provides a refrigerator, including the hinge structure in the refrigerator provided in Embodiment 1.

[0060] Working principle:

[0061] like Figure 4 As shown, when the lower door needs to be disassembled separately, remove the second screw 04, rotate the second middle hinge assembly 02 horizontally by 90 degrees around the first hinge axis 017 to release the vertical constraint between the first torsion latch structure 011 and the second torsion latch structure 012, and then move the second middle hinge assembly 02 downward so that the first torsion latch structure 011 disengages from the second torsion latch structure 012, thereby separating the first middle hinge assembly 01 and the second middle hinge assembly 02 and completing the disassembly of the lower door.

[0062] When it is necessary to disassemble the upper and lower door bodies, one person can remove the second screw 04, rotate and move the second middle hinge assembly 02 to remove the lower door body, while another person removes the first screw 03 and the third screw 05, and moves the first middle hinge assembly 01 to remove the upper door body.

[0063] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0064] By dividing the traditional refrigerator hinge into two detachable hinge components, the system offers flexibility and operability. When the lower door needs to be removed separately, the second hinge component can be directly detached from the first hinge component to release the lower door from its fixation. This allows the lower door to be removed without removing the upper door, avoiding the operational complexity caused by having to remove the upper door first.

[0065] In addition, by setting the first screw and the third screw, the installation and disassembly of the first hinge assembly and the refrigerator body are facilitated, thereby improving the ease of installation and disassembly.

[0066] By setting a second screw, the installation and disassembly of the second hinge assembly and the first hinge assembly can be facilitated, improving the convenience of installation and disassembly. The first hinge assembly and the second hinge assembly are fixed in the horizontal direction, improving the fixing effect and making it easy to release the fixation.

[0067] By setting a first hinge axis, the upper door can be rotated easily; by setting a second hinge axis, the lower door can be rotated easily, thus improving the refrigerator's performance.

[0068] By setting a first torsion buckle structure and a second torsion buckle structure that are torsionally connected, the first middle hinge assembly and the second middle hinge assembly are fixed in the vertical direction, thereby improving the fixing effect. There is a gap between the second middle hinge assembly and the lower door body, which makes it easy to release the fixation.

[0069] By setting the splicing surface, interference is avoided when the first hinge component and the second hinge component twist and assemble or disassemble, thus ensuring the effectiveness of use.

[0070] By setting a latch, it is easy to engage the second hinge assembly to rotate, thereby facilitating the release of the fixation between the first hinge assembly and the second hinge assembly.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
