Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating box for a refrigerator provided with a reinforcing member at a lower portion of an outer box. 2. Description of the Related Art A conventional refrigerator is disclosed in Japanese Patent Application Laid-Open No. 5-604.
No. 56 was disclosed. [0003] A conventional heat insulating box of a refrigerator will be described below with reference to Figs. Reference numeral 1 denotes an outer box including a side plate 1a and a top plate 1b. Reference numeral 2 denotes a front flange formed by inwardly bending the front opening edge of the outer box 1. Reference numeral 3 denotes a back flange that is folded back to the back of the front flange 2. Reference numeral 4 denotes a front flange 2 and a rear flange 3 that are continuously provided at the same position. Hole. Reference numeral 5 denotes an inner box formed of a synthetic resin. Reference numeral 6 denotes an inner box 5 insertion groove 3a formed between the rear plate flange 3 and the rear plate flange 3, and the side plate 1a and the top plate 1 are formed.
After the pipe groove 7 is formed between the pipe 7 and the flange b, a heat dissipation pipe 8 for preventing dew is inserted into the pipe groove 7 at the flange. Reference numeral 9 denotes a partition provided on the left and right sides of the inner box 5 for partitioning.
Reference numeral 10 denotes a middle partition hole formed in the middle partition 9 and located on the back surface of the hole 4. [0004] Reference numeral 11 denotes an inner box hole located at the back of the partition hole 10 formed in the inner box 5. Numeral 12 denotes a hinge abutting on the front surface of the partition, and a hinge hole 13 is formed. Reference numeral 15 denotes a U-shaped reinforcing member in which the front portion 14 abuts on the rear surface of the rear flange 6 and extends upward from the middle partition 9. 16 is a hinge hole 13 and a front flange 2
Partition hole 10 which passes through hole 4 provided in
It is a screw that is tightened and fixed. Reference numeral 17 denotes a foam heat insulating material filled between the inner box 8 and the outer box 1 by foaming. However, in the above-described configuration, the screw 16 fixing the hinge 12 is fastened and fixed only to the partition hole 10 via the front flange 2 and the rear flange 3. Therefore, when a load is applied to the hinge 12, the partition 9 against which the hinge 12 abuts is rattled. Further, since the reinforcing member 15 is not connected and fixed to the surrounding members in the foamed heat insulating material 17, the reinforcing member It has been regarded as one of the factors that cause the outer box 1 to be twisted and tilted without fulfilling the function of the above. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a refrigerator that minimizes rattling of a partition even when a load is applied to a hinge, and further prevents twisting of the outer box and tilting. And [0008] In order to solve the above-mentioned drawbacks, a refrigerator according to the present invention has an outer box comprising a side plate and a top plate, and is formed by bending inward the entire opening edge of the outer box. Between the front flange, the back flange folded back to the front flange, the hole continuously provided at the same position in the front flange and the back flange, and between the back flange continuously with the back flange. After forming an inner box insertion groove on the side plate and a flange after forming a pipe groove between the side plate and the top plate,
A radiation pipe for dew-prevention inserted into the pipe groove, a partition for partitioning the inside of the inner box, a partition hole located on the back of the hole portion in the partition, and the inside formed in the inner box. An inner box hole located at the back of the partition hole, a hinge abutting on the front surface of the middle partition, a hinge hole located at the hole front surface of the hinge, and abutting on the rear surface of the rear flange. more will extend out the U-shaped reinforcing member upward from the front portion said intermediate partition having a front portion, said U-shaped
A protrusion is integrally formed on the front surface of the reinforcing member, and the protrusion is
To the hinge side so as to abut the inner box without touching the lunge
The shape is narrowed down, and it is located on the back of the inner box hole of the projection.
Screw holes, the hinge holes, and the front flange
The hole provided on the back side flange, and the intermediate partition hole;
And the inner box hole is integrally fixed with a long screw, and a foam insulation material is filled between the inner box and the outer box. According to the present invention, the U-shaped reinforcing member can be integrally fixed by the screw from the hinge by the above-described structure.
Even if a load is applied to the hinge, it is possible to minimize the backlash of the partition by using the reinforcing member, and further, since the reinforcing member is fixed to the partition, the outer box is twisted and tilted. To prevent that. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A refrigerator according to an embodiment of the present invention will be described below with reference to the drawings. The same components as those in the related art are denoted by the same reference numerals, and detailed description thereof will be omitted. In FIG. 1 to FIG. 5, reference numeral 19 designates a front portion 14 of the U-shaped reinforcing member 15 which is located in a straight line from the hinge hole 13 toward the back of the outer box 1 and which does not contact the rear flange 6. The protrusion has a shape narrowed toward the hinge 12 so as to abut on the inner box 5. Reference numeral 20 denotes a screw hole having a hole diameter in which a screw from the hinge 12 provided on the coaxial line of the hinge hole 13 is tightened. 21 passes through the hinge hole 13, the hole 4, the partition hole 10, and the inner box hole 11, and
9 is a long screw having a length long enough to tighten the screw, and the screw from the hinge 12 to the projection 19 is firmly fixed with a long screw 21. In the refrigerator configured as described above,
Since the U-shaped reinforcement member 15 can be integrally fixed from the hinge 12 by the long screw 21, even if a load is applied to the hinge 12, the U-shaped reinforcement member 15 is pressed and fixed to the U-shaped reinforcement member 15, so that the middle partition 9 is removed The rattling can be minimized, and since the U-shaped reinforcing member 15 is fixed to the partition, the reinforcing effect is further increased, and even if an external force is applied to the refrigerator body, the outer box 1 is twisted, This has the effect of preventing the tilt from occurring. As described above, the present invention provides a U-shaped reinforcing portion.
A convex part is integrally formed on the front part of the material, and the convex part is formed on the rear flange.
Narrow down to the hinge side so that it does not touch the inner box
Screw located on the back of the inner box hole of the projection
A hole, the hinge hole, the front flange and the back flange.
The hole provided in the flange, the partition hole,
Since the box hole and the long screw are integrally fixed , even if a load is applied to the hinge, the rattling of the middle partition can be minimized by using the reinforcing member. By being fixed, the outer box is prevented from twisting and tilting.
