Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerators, and particularly relates to a hinge and a refrigerator in a hanging cabinet door type embedded refrigerator. Background Art

[0002] For four-door refrigerators such as French-style refrigerators, the compartments of the refrigerator are longitudinally divided into a refrigerating compartment and a freezing compartment by a middle cross beam. When the above refrigerator is used as a hanging cabinet door type embedded refrigerator, due to the requirement of a small gap (3 - 5 mm) between cabinet doors in the cabinet industry, in order to solve the problem that the refrigerator door of the hanging cabinet door does not interfere with the adjacent cabinet when opening and closing, as Figure 1 shown, it is necessary to install link hinges 2 corresponding to each door on the middle cross beam 1. The problem caused by this is that the stacked link hinges 2 occupy a large height of the middle cross beam, and the middle cross beam with a large height will reduce the volume of the refrigerator and increase the manufacturing cost. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art, and provide a hinge in a hanging cabinet door type embedded refrigerator that can effectively reduce the height occupied on the middle cross beam.

[0004] The utility model also provides a refrigerator using the above-mentioned hinge in a hanging cabinet door type embedded refrigerator.

[0005] The first aspect of the utility model provides a hinge in a hanging cabinet door type embedded refrigerator, which includes a hinge transmission assembly. One end of the hinge transmission assembly is hinged to a hinge base for connecting the middle cross beam, and the other end is hinged to a connecting plate for connecting the refrigerator door; there are two groups of the hinge transmission assemblies, which are hinged in two corresponding mounting seats on the same hinge base, and there are two groups of connecting plates, which are respectively connected to the upper and lower refrigerator door bodies on the same side.

[0006] The second aspect of the utility model provides a refrigerator using the above-mentioned hinge in a hanging cabinet door type embedded refrigerator, which includes a middle cross beam and a refrigerator door body installed with the above-mentioned hinge in a hanging cabinet door type embedded refrigerator.

[0007] By combining the two groups of link hinges between the middle cross beam and the upper and lower refrigerator door bodies into one group, the utility model can not only reduce the hinge installation height required for the middle cross beam, reduce the height of the middle cross beam itself, and achieve the purpose of increasing the volume of the refrigerator, but also has the advantages of simple structure, convenient assembly and low manufacturing cost.

[0014] Referring to Figure 2 , a middle hinge for a hanging cabinet door type embedded refrigerator provided in this embodiment includes a hinge transmission assembly 4. One end of the hinge transmission assembly 4 is hinged to a hinge base 3 for connecting a middle crossbeam 1, and the other end is hinged to a connecting plate 5 for connecting a refrigerator door 2. In order to integrate the hinges corresponding to the upper and lower door bodies (on the same side) of the middle crossbeam 1, so as to achieve the purpose of reducing the occupied height, the technical solution of this embodiment is, in combination with Figure 3 , there are two groups of hinge transmission assemblies 4, which are hinged in two corresponding mounting seats 6 on the same hinge base 3. The connecting plates 5 are in two groups and are respectively connected to the upper and lower refrigerator door bodies 7 on the same side.

[0015] Since the hinges corresponding to the upper and lower refrigerator door bodies (on the same side) of the middle crossbeam 1 are integrated together, compared with the hinges separated up and down in the background art, the distance between the two hinges is closer, so the height of the middle crossbeam 1 occupied is smaller, thereby the self-height of the middle crossbeam 1 can be reduced, so that the refrigerator volume can be increased, and at the same time, the hinge cost is reduced and the refrigerator manufacturing cost is saved.

[0016] In this embodiment, referring to Figure 4 , the hinge base 3 and the two mounting seats 6 are integrally formed. Specifically, in this embodiment, a sheet metal material is used to form an integrally formed hinge base 3 (including two mounting seats 6) such as Figure 4 through blanking, bending and forming processes. Compared with using two hinges on the upper and lower refrigerator door bodies 7 on the same side respectively, not only the manufacturing cost of the hinge is reduced, but also the disadvantages such as complex process and connection instability caused by the connection and fixation of multiple hinge components are avoided.

[0017] In this embodiment, referring to Figure 4The bottom surface of the hinge base 3 is provided with a connection hole 11 for connecting with the middle cross beam 1, and one side of the bottom surface is provided with a space 31 for installing the hinge transmission assembly 4. The space 31 is penetrated by an axis I 32 and an axis II 33. The axis I 32 is located in the middle of the space 31, and two mounting seat plates 34 are penetrated thereon. There is a gap between the opposite surfaces of the two mounting seat plates 34, and the space 31 occupied by the other side of the mounting seat plate 33 is the mounting seat 6 for installing the hinge transmission assembly 4. The axis II 33 is located at the end of the space 31, and passes through the space 31 to connect with the two mounting seat plates 34 and the two sets of hinge transmission assemblies 4. The purpose is to have the advantages of simple structure and convenient assembly.

[0018] In this embodiment, see Figure 5 The hinge transmission assembly 4 includes a first transmission link 41 hinged on the shaft Ⅰ32, a second transmission link 42 is hinged on the middle part of the first transmission link 41, the other end of the second transmission link 42 is hinged on the connecting plate 5, a third transmission link 43 is hinged on the tail of the first transmission link 41, the other end of the third transmission link 43 is also hinged on the connecting plate 5, and the upper and lower surfaces of the middle part of the second transmission link 42 are hinged with a fourth transmission link 44, the other end of the fourth transmission link 44 is hinged on the shaft Ⅱ33, and is limited in the corresponding mounting seat 6.

[0019] Since the lever arm formed by the hinge transmission assembly 4 is relatively long, a relatively wide rotation space can be formed between the middle crossbeam 1 of the refrigerator body and the refrigerator door body 7. In particular, when the refrigerator door body 7 is opened, the distance between the refrigerator door body 7 and the middle crossbeam 1 of the refrigerator body is farther than that between the door body and the body of an ordinary refrigerator. Therefore, after the built-in refrigerator using the above-mentioned hinge is placed in a relatively deep and narrow space, when the refrigerator door body 7 is opened, the refrigerator door body 7 can easily escape from the deep and narrow space or other objects in the deep and narrow space (not shown), effectively avoiding interference; see Figure 6 and Figure 7 When the refrigerator door 7 is closed, the folding and contraction of the hinge transmission assembly 4 can also make the middle cross beam 1 of the refrigerator body and the refrigerator door 7 tightly closed without affecting the sealing of the refrigerator.

[0020] In this embodiment, combined with Figure 5 and Figure 6 The connecting plate 5 is L-shaped, the horizontal surface is hinged with the second transmission link 42 and the third transmission link 43, the vertical surface is arranged in parallel in front of the corresponding refrigerator door 7, and a clearance space 9 for accommodating the vertical surface is provided on the refrigerator door 7. The purpose is that it not only has the advantage of convenient installation, but also the setting of the clearance space 9 can ensure the stability of the transmission structure of the two hinge transmission groups 4, and effectively prevent the occurrence of mutual interference.

[0021] This embodiment also provides a refrigerator using the hinge in the hanging cabinet door type embedded refrigerator described above, which includes a middle cross beam 1 and a refrigerator door body 7 installed with the hinge in the hanging cabinet door type embedded refrigerator described above.

[0022] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
