The present invention relates to a side panel-front panel coupling structure of a refrigerator, and more particularly, to a side panel-front of a refrigerator which can greatly reduce a defective rate by preventing the leakage of urethane liquid when the side panel and the front panel of the refrigerator body are coupled. It relates to a panel coupling structure.

As shown in FIG. 1, generally, the kimchi refrigerator 50 is for refrigeration of contents such as kimchi or vegetables, and includes a refrigerator body in which a storage chamber 21 opened upward to accommodate a kimchi container is formed. 20), and the door 30 is installed in the upper portion for opening and closing the storage chamber 21 of the refrigerator main body 20. Of course, the refrigerator main body 20 is provided with a compressor, a condenser, a capillary tube, and an evaporator constituting a refrigerant cycle for cooling the inside of the storage compartment 21, but are omitted in the drawings since they are all disclosed in a general kimchi refrigerator. .

In addition, as shown in Figure 2a and 2b, the kimchi refrigerator main body 20 is filled with a heat insulating material (not shown) such as urethane between the inner wound 22 and the outer wound 23 forming the storage chamber 21. It is composed.

In addition, the outer case 23 has a configuration in which the side panel 25 and the front panel 26 are coupled to each other, and both of them take a manner of being fastened by bolts 27. In particular, since the side panel-front panel coupling structure is located at the corner of the refrigerator body, the front portion of the side panel 25 is bent in a '-' shape as a whole.

Here, the side panel 25 includes an inverting portion 25b in which one sheet is inverted in the middle, an overlapping portion 25c extending while being inverted from the inverting portion 25b and overlapping in two sheets, and It is comprised from the free end 25a branched from the overlap part 25c and bent toward the inner side 22 of Kimchi refrigerator.

The inverting portion 25b of the side panel 25 is inflated in an arc shape having a relatively large radius of curvature to maintain the strength and rigidity of this portion greatly.

On the other hand, the front panel 26 coupled to the side panel 25 has a relatively flat shape, and the recessed portion 26b which is recessed to the rear so as to ride over the inverting portion 25b of the side panel 25. ) And a free end 26a extending from the concave portion 26b and in contact with the overlap portion 25c. The free end 26a extends in contact with the vicinity of the front edge of the side panel 25.

As a result, as shown, the side panel 25 and the front panel 26 are finally joined by the bolt 27 in a state where the overlapping portion 25c of the side panel and the free end 26a of the front panel overlap. . About 14 to 16 bolts 27 are used in the vertical direction.

After the coupling of the side panel 25 and the front panel 26 is completed, the urethane liquid is supplied between the inner and outer wounds 22 and 23 to form a heat insulation portion.

However, during the assembling process of the side panel 25 and the front panel 26, warping may occur between the bolt and the bolt due to stress generated on the side panel or the front panel, and thus the urethane supplied The fluid leaked out through the bolt holes in front of the front panel, which often led to product defects (see arrow in Figure 2).

In order to prevent this, conventionally used to prevent the leakage of the urethane liquid by inserting a sealing member (not shown) in the 'B' portion, but due to this increases the number of parts and the cost of parts is greatly reduced productivity.

Furthermore, since one free end 25a of the side panel 25 is embedded in the corner of the kimchi refrigerator in a branched state, durability to external force may be lowered.

In the drawing, only the structure of the Kimchi refrigerator is shown, but the general refrigerator has the same structure.

The present invention has been made to solve the above problems, an object of the present invention is to prevent the leakage of urethane liquid when the side panel and the front panel at the front edge of the refrigerator body to significantly reduce the defective rate of the side panel of the refrigerator It provides a front panel assembly structure.

Hereinafter, with reference to the accompanying Figures 3 to 5 will be described in detail with respect to the side panel-front panel coupling structure in the kimchi refrigerator as a preferred embodiment of the present invention. Coupling structure shown in the drawing has the same cross-sectional structure in the vertical direction of the kimchi refrigerator so it will be described only based on the cross-sectional view.

In addition, the main body of the kimchi refrigerator according to the present invention is provided with a compressor, a condenser, a capillary tube, and an evaporator constituting a refrigerant cycle for cooling the inside of the storage chamber, but since it is a configuration disclosed in all the general kimchi refrigerator, it is omitted from the drawing.

As shown, the coupling structure 1000 of the side panel 100-front panel 200 of the kimchi refrigerator according to an embodiment of the present invention is located at the front edge of the kimchi refrigerator.

First, the front portion of the side panel 100 is composed of the inverting portion 110, the overlapping portion 120, the rear extension 130, the intermediate inclined extension 140 and the free end inclined extension 150. .

Here, the inversion unit 110 is formed in an arc shape as a portion that is bent in order to overlap one sheet of two. As a result, the strength and rigidity at this portion are largely maintained. However, the inversion unit 110 does not have to be completely arc-shaped, but may have a curved shape close to the arc.

Next, the overlapping part 120 is bent from the inverting part 110 and overlapped in two pieces and extends from the front side to a part of the side, and thus has a '-' shape. The overlapping portion 120 is preferably configured such that two sheets are completely in contact with each other.

In addition, the rear extension 130 is a portion which is branched from the overlapping part 120 and is spaced apart from the overlapping part 120 and extends toward the inversion part 110.

In addition, the intermediate inclined extension 140 is a portion which is bent and extended forward from the rear extension 130, and the free end inclined extension 150 is rearward from the intermediate inclined extension 140 again. It is an obliquely extending part.

On the other hand, one side portion of the front panel 200 which is coupled to the front portion of the side panel 100, the concave portion 210, the convex portion 220 extending from the concave portion 210, and the convex portion ( And a panel free end extension 230 extending from 220.

First, the concave portion 210 is configured to pass between the inverted portion 110 and the intermediate inclined extension portion 140 of the side panel 100, but has the inverted portion 110 in front. In addition, the concave portion 210 is bent in a trapezoidal channel shape to maintain a relatively large rigidity compared to the square shape.

The convex portion 220 extends after the concave portion 210 and is accommodated between the overlapping portion 120 and the rear extension portion 130 of the side panel 100. In addition, the convex portion 220 is bent in a trapezoidal channel shape to maintain a relatively large rigidity compared to the square shape.

In addition, the panel free end extension 230 extends from the convex portion 220 and has a structure toward the rear extension 130 of the side panel.

In this case, the boundary point between the intermediate inclined extension part 140 and the free end inclined extension part 150 and the point A between the front panel 200 and the intermediate inclined extension part 140 and the recess 210 of A point between corners B, a point C between the rear extension 130 and the panel free end extension 230, a point D between the front of the convex portion 220 and the rear of the overlapping portion 120. , And the point E between the inversion portion 110 and the bottom surface of the recess 210 are in contact with each other.

As such, when the side panel 100 and the front panel 200 are assembled while contacting at five points, mutually elastic resistance acts so that they can be firmly disposed in place without moving.

That is, even without a fastening means such as a bolt, the side panel 100 and the front panel 200 are firmly coupled and can ensure a reliable sealing for the urethane liquid supplied.

As described above, although the drawings describe the kimchi refrigerator, it is of course applicable to a general refrigerator.

According to the present invention having the above-described configuration, since the sealing is made at five points between the side panel and the front panel when viewed from a flat cross section, it is possible to maintain reliable sealing.

In addition, according to the present invention, since it is elastically and firmly assembled at five points between the side panel and the front panel, there is no need for a separate fastening means such as a bolt, thereby reducing the labor cost and component cost.

In addition, according to the present invention, since there is no need for a separate sealing member for preventing the leakage of the urethane liquid, it is possible to reduce the labor and production cost.

In addition, according to the present invention, since the bolt head is not exposed to the outside of the main body of the refrigerator, the shape can be naturally flattened and the interference with the surrounding structure can be minimized.

In addition, according to the present invention, the side panel and the front panel structure is densely arranged at the front edge of the refrigerator, thereby improving durability compared to the conventional.
