STRUCTURE FOR ASSEMBLING BACK-PLATE IN KIMCHI REFRIGERATOR}

The present invention relates to a back plate coupling structure of the kimchi refrigerator, and more particularly to a back plate coupling structure of the kimchi refrigerator to improve the back plate coupling structure of the kimchi refrigerator to prevent the leakage of the foam material.

In general, unlike conventional refrigerators, kimchi refrigerators are used to ferment fermented foods such as kimchi to improve the taste of foods more appropriately, and are mainly used to properly ripen foods or maintain the taste. do. The kimchi refrigerator is bent largely in a cold and direct cooling according to the cooling method, the kimchi refrigerator is based on the principle of the conventional kimchi ripening principle, that is, the kimchi ripening time and temperature of the ground kimchi poison.

1 is a perspective view showing a kimchi refrigerator having a conventional structure, Figure 2 is a cross-sectional view showing a partial back plate mounting portion, Figure 3 is a cross-sectional view showing a section "AA" shown in Figure 2, As shown, the kimchi refrigerator has a pair of upper storage chambers 15 upwardly opened in the upper region along a vertical direction, and a pair of lower storage chambers 19 disposed at a front surface at the bottom and spaced apart from each other in the left and right directions. Each of the main body 11 and the upper storage chamber 17 coupled to the main body 11 so as to rotate the opening and closing of the upper storage chamber 15 and the plurality of retractably received inside the lower storage chamber 19 are formed. The drawer 21 is configured to include.

The main body 11 has an outer appearance and is disposed to be spaced apart from the outer case 12 to which the back plate 16 is coupled to the rear portion thereof, and with a filling interval of the foam material 14 inside the outer case 12. Each of the inner case 13 forming the upper storage chamber 15 and the lower storage chamber 19 therein, and the upper cover 18 covering the upper surface of the outer case 12 and the back plate 16, respectively. Both side ends of the outer case 12 are formed with a coupling surface 12a vertically bent inward to allow the back plate 16 to be coupled, and a predetermined portion of both ends of the back plate 16 is coupled to the coupling surface ( It is mounted superimposed on 12a) and is screwed by the bolt 16a.

In the upper rear region of the main body 11, the upper storage chamber doors 17 are coupled to each other so as to open and close the upper storage chamber 15 around the rotational shaft disposed along the horizontal direction, respectively, and the lower rear of the main body 11. In the region, the machine chamber 51 is formed so that a compressor (not shown) or the like, which is a cooling device that maintains the inside of the upper storage chamber 15 and the lower storage chamber 19 at an appropriate temperature or less, can be accommodated.

Kimchi refrigerator configured as described above is covered with the outer case 12 to surround the inner case 13, the back plate 16 is mounted to cover the back of the outer case 12, the coupling of the outer case 12 The back plate 16 is screwed to the surface 12a with bolts 16a, and the upper cover 18 is covered on the upper surface of the outer case 12 and the back plate 16 to which they are coupled.

After the upper cover 18 is covered, the foaming material 14 is foamed between the inner case 13 and the outer case 12 so that the thermal insulation state is maintained.

However, in the Kimchi refrigerator having a conventional structure as described above, the foam may leak between the back plate 16 and the upper cover 18 during the mounting process of the upper cover 18, and the rear portion of the outer case 12 may be formed. Since the plurality of bolts 16a must be coupled in the process of covering the back plate 16, there is a problem of increasing the number of assembly operations.

The object of the present invention devised in view of the above point is to improve the coupling structure of the back plate coupled to the outer case of the kimchi refrigerator to reduce the assembly labor and at the same time prevent the leakage of foam material back plate of the kimchi refrigerator In providing a coupling structure.
