    This, the hinge (1) of the press-formed metal material is fixed to the upper surface of the cabinet 10 through a plurality of fixing screws (s), the upper door on one lower surface of the front surface of the hinge (1) The hinge shaft 2 to which the hinge groove 40a formed on the upper surface of the 40 is rotatably coupled is formed.
    However, in such a conventional upper hinge assembly, there are many problems listed below.
    First, since the hinge body 1 is formed by pressing a metal, there is a problem of causing a unit cost increase relative to the plastic injection molding.
    Second, since the hinge coupling portion 2 of the hinge body 1 and the hinge coupling portion of the upper door 40 are very fragile, a problem occurs that the upper door 40 sags downward after a long time.
    Third, since the upper door 40 is rotated around the hinge shaft 2 of the metal material, cracks or peeling of the hinge are generated.
    The present invention was created in order to solve such a conventional problem, it is possible to form a hinge through the plastic water to reduce the cost, in particular to prevent the sag of the upper door and damage to the hinge coupling portion in advance. It is an object of the present invention to provide an upper hinge assembly of a refrigerator.
    In order to achieve the above object, the upper hinge assembly of the refrigerator according to the present invention is partitioned into a freezing compartment and a refrigerating compartment through an intermediate partition, and a cabinet provided with shelves and pockets for storing foods therein; Upper and lower doors positioned in front of the cabinet to selectively open and close the freezer compartment and the refrigerating compartment of the cabinet; A door cap fixedly installed on an upper surface of the upper door and having a hinge groove formed at one side thereof; And an upper hinge having a fixing plate formed on one side of the cabinet through a plurality of fixing screws, and a guider extending from the lower end of the other side of the fixing plate and inserted into the hinge groove of the door cap.

    Such a characteristic configuration and the resulting effects of the present invention will become more apparent from the following detailed description of the invention with reference to the accompanying drawings.
    Figure 3 is an exploded perspective view of the upper hinge assembly according to the present invention, Figure 4 is a combined cross-sectional view. Hereinafter, a description will be given with reference to FIG. 1.
    First, referring to FIG. 1, a cabinet 10 having a rectangular frame shape is provided.
    The cabinet 10 is partitioned into a freezing compartment 20 and a refrigerating compartment 30 for freezing and refrigerating foodstuffs through an intermediate partition 11 installed in a substantially central plane, and in particular, each of these freezing compartments 20. And a plurality of shelves 40 and pockets 50 are provided on the refrigerating chamber 30 for smooth storage of foods.
    Meanwhile, the freezing compartment 20 and the refrigerating compartment 30 partitioned through the middle partition 11 are selectively opened and closed through upper and lower doors 60 and 70 positioned in front of the cabinet 10.
    At this time, the upper and lower doors (60, 70) through the plurality of hinge assemblies, that is, the upper hinge assembly to selectively open and close the freezer compartment 20 and the refrigerating compartment (30) through the upper and lower doors (60, 70). The hinge is rotatably coupled to one side of the cabinet 10 through the intermediate hinge assembly and the lower hinge assembly.
    That is, the lower surface of the upper door 60 and the upper surface of the lower door 70 are hinged so as to be rotatable, respectively, on the intermediate hinge assembly located at the center of the rear of the cabinet 10, and the upper surface of the upper door 60. The hinge is rotatably coupled to the upper hinge assembly and the lower surface of the lower door 70 respectively.
    In this case, in particular, the upper hinge assembly 100 having the upper surface of the upper door 60 rotatably hinged has a characteristic configuration of the present invention, and the detailed structure thereof will be described with reference to FIGS. 3 and 4. Same as
    On the upper surface of the upper door 60 for selectively opening and closing the freezer compartment 20, a door cap 110 is fixedly installed to consider aesthetics, and in particular, the door cap 110 adjacent to the hinged part is installed. The hinge groove 111 is formed in the inner surface at a predetermined depth.
    Meanwhile, the upper hinge 120 is fixedly installed on the upper surface of the cabinet 10, and the upper hinge 120 has a fixing plate 121 fixedly installed on the cabinet 120 through a plurality of fixing screws S. .
    In addition, a guider 122 inserted into the hinge groove 111 of the door cap 110 is extended to one lower surface of the fixing plate 121.
    At this time, if the size of the hinge groove 111 of the door cap 110 described above is sufficiently large, and the guider 122 of the upper hinge 120 inserted therein is sufficiently large, it is possible to reinforce the strength to some extent. In order to prevent the deflection of the upper door 60 by performing a certain strength reinforcement, as shown in FIG. 4, the auxiliary hinge groove 122a is formed at a predetermined depth on the inner surface of the guider 122 of the upper hinge 120. It may be preferable to further provide an auxiliary guider 111a on the bottom surface of the hinge groove 111 of the door cap 110 so as to be rotatably inserted into the auxiliary hinge groove 122a.
    That is, the guider 122 of the upper hinge 120 is hinged to the hinge groove 111 of the door cap 110 as well as the auxiliary guider 111a is hinged to the auxiliary hinge groove 122a as a result. The upper door 60 is double hinged to the upper hinge 120.
    Meanwhile, the fixing plate 121 and the guider 122 of the upper hinge 120 are integrally formed through plastic, that is, through injection molding, in consideration of the problem of unit cost increase occurring during press working. It would be very desirable in terms of cost reduction.
    In the present invention configured as described above, although the upper door 60 is not shown, the lower surface of the upper door 60 is pivotally hinged to the intermediate hinge assembly located in the approximately center surface of the cabinet 10, as well as the upper surface of the door cap ( The hinge groove 111 of the 110 and the auxiliary guider 111a are pivotally supported by the guider 122 and the auxiliary hinge groove 122a of the upper hinge 120 fixedly installed on one side of the cabinet 10. .
    In this case, the door cap 110 is primarily maintained by the hinge coupling between the hinge groove 111 and the guider 122 of the upper hinge 120, and secondly, the bottom of the hinge groove 111 Hinge coupling between the auxiliary guider 111a protruding from the surface and the auxiliary hinge groove 122a formed in the center surface of the guider 122 can achieve greater rigidity.
    That is, since they have a large contact area with each other, even when the upper hinge 120 itself is molded into an injection molding, sufficient rigidity is maintained. Therefore, it is possible to prevent the sag due to the weight of food products and the weight of the upper door 60 itself even after a long time passes.
    On the other hand, the above-described embodiment is merely described one preferred embodiment of the present invention, the scope of application of the present invention is not limited to such, and can be changed as appropriate within the scope of the same idea. For example, the shape and structure of each component shown in the embodiment of the present invention can be modified.
    As described above, according to the upper hinge assembly of the refrigerator according to the present invention, the upper hinge to which the upper door is hinged is molded into an injection molding, thereby reducing the unit cost in comparison with the press. The hinge is double hinged to maintain sufficient rigidity, thereby preventing the sagging of the upper door in advance.
