2 to 5, the reinforcing upper hinge 20 of the kimchi refrigerator according to an embodiment of the present invention includes a hinge bracket 22 and a hinge shaft 40.

Hinge bracket 22 is fastened to the upper edge of the body (10).

Hinge bracket 22 forms a plurality of insertion holes 24, the fastening screw 30 is fastened to the fastening hole 12 formed in the main body 10 through the insertion hole 24, thereby the hinge bracket 22 ) Is firmly fixed to the kimchi refrigerator body (10).

The hinge bracket 22 is bent in two stages, and is bent in the lateral direction toward the fastening portion of the front door 50.

The hinge bracket 22 forms a protruding surface portion 26 in which an area set to reinforce rigidity protrudes to one side by press working.

The protruding surface portion 26 may be formed to conform to the curved shape of the hinge bracket 22.

The hinge bracket 22 may be processed by molding into a mold or cutting a metal plate by a press.

Hinge shaft 40 is fixed to the installation hole 28 of the hinge bracket 22, the lower side is hinged to the front door 50 is formed in a cylindrical shape having a hollow inside.

2, the hinge shaft 40 includes a hinge portion 42, a coupling portion 46, and a stepped portion 44.

The hinge shaft 40 forms a cutout 48 in which the hollow is open to one side.

The hinge shaft 40 may roll up a rectangular plate body to form a hollow and an incision 48 that are vertically penetrated.

The hinge portion 42 is inserted into the hinge hole 52 of the front door 50 is configured to rotate.

The coupling portion 46 has a narrow diameter cross section at the upper end of the hinge portion 42 and is bent and pressed outwardly from the installation hole 28 to fix the hinge shaft 40 to the upper surface of the hinge bracket 22. do.

The stepped portion 44 is formed as a stepped portion at the interface between the coupling portion 46 and the hinge portion 42, and supports the peripheral edge of the bottom edge of the installation hole 28, the hinge shaft 40 on the bottom surface of the hinge bracket 22 Fix it.

That is, a portion that is bent and pressed outward from the upper side of the coupling portion 46 press-fixes the upper surface of the hinge bracket 22, and the hinge jaw 44 supports the bottom surface of the hinge bracket 22 to fix the hinge shaft. 40 is firmly fixed to the hinge bracket 22 in a state where the rigidity is reinforced.

Then, the coupling portion 46 of the hinge shaft 40 is bent and pressed outwardly to be fixed to the upper surface of the hinge bracket 22, and subsequently additionally fixed by welding 47 so that the rigidity is further reinforced.

On the other hand, the engaging portion 46 and the stepped portion 44 of the hinge shaft 40 is formed by cutting the circumference of the upper outer peripheral surface of the hinge portion 42 to narrow the diameter.

The upper hinge 2 above prevents the upper hinge 20 from being exposed to the outside and covers the cover 60 in consideration of aesthetics.

Hereinafter, with reference to the accompanying drawings to look at the action of the reinforcing hinge of the kimchi refrigerator according to an embodiment of the present invention.

First, as shown in Figure 5 (a) to Figure 5 (c), looks at the state of forming the upper hinge 20.

Referring to Figure 5 (a), after forming the coupling portion 46 having a smaller diameter of the hinge portion 42 in the hinge shaft 40 through cutting or mold processing, the hinge bracket 22 Move to the installation hole 28.

And, referring to Figure 5 (b), while fitting the engaging portion 46 of the hinge shaft 40 into the installation hole 28 of the hinge bracket 22, the stepped portion 44 is the bottom surface of the installation hole 28 To support around the edges.

Then, while pressing the engaging portion 46 of the hinge shaft 40 protruding upward, the upper side of the hinge bracket 22 is firmly fixed by pressing the upper portion of the hinge shaft 40.

At this time, as the engaging portion 46 of the hinge shaft 40 is bent to the outside, together with the stepped portion 44 of the bottom, the hinge shaft 40 is firmly fixed to the hinge bracket 22 in a state where rigidity is reinforced. will be.

Subsequently, referring to FIG. 5 (c), the coupling portion 46 of the hinge shaft 40 is bent and pressed outward and fixed to the upper surface of the hinge bracket 22, and then the coupling portion 46 and the hinge are connected. By further fixing the upper surfaces of the bracket 22 by welding 47 to each other, the hinge shaft 40 is more firmly fixed to the hinge bracket 22.

As described above, the assembled state of the front door 50 is pivotally assembled to the kimchi refrigerator body 10 using the manufactured upper hinge 20.

By inserting the fastening screw 30 into the plurality of insertion holes 24 formed in the hinge bracket 22 and penetrating the fastening hole 12 formed in the main body 10, the hinge bracket 22 is the Kimchi refrigerator main body. Fix firmly to (10).

Then, the hinge part 42 is inserted into the hinge hole 52 of the front door 50 in the hinge shaft 40 fixed to the hinge bracket 22 to be rotatably fixed.

As such, the reinforcing upper hinge 20 of the kimchi refrigerator according to the present invention includes a coupling part 46 having a small cross-sectional area of diameter at the upper end of the hinge shaft 40 coupled to the hinge bracket 22. After the lower portion is coupled by 44, the coupling portion 46 is bent to the outside and welded to the hinge bracket 22 to fix the support rigidity of the hinge shaft.

In addition, unlike machining and using the hinge shaft 40 in a conventional cylindrical shape, it is possible to lightly maintain the weight of the hinge shaft while maintaining sufficient strength by processing and using a cylindrical shape with an empty inside.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. I will understand.
