4A, 4B at the rear thereof.

The back plate 6 is provided on the back surface of the refrigerator body 2 and constitutes the rear wall of the refrigerator body 2 . Like the outer wall panel 3 , the inner box 7 is arranged inside the back plate 6 (ie, in front of the back plate 6 ), and a foamed heat insulating material is filled between the back plate 6 and the inner box 7 .

FIG. 2 is a perspective view of a reinforcing corner piece 4A arranged at the lower part of the outer wall panel 3 on the left side of the refrigerator main body 2 . As shown in FIG. 2, it is formed so that it may become a substantially "L" shape in a side view. Further, the longitudinal cross section of the corner reinforcement 4A at the side surface 4e in the front-rear direction and the cross section at the side surface 4f in the longitudinal direction of the reinforcement corner 4A are formed in a substantially "L" shape. However, not limited to this, for example, each cross section may be formed approximately

glyph. The reinforcing corner fittings 4B are configured to be substantially symmetrical in the left-right direction with respect to the reinforcing corner fittings 4A. Therefore, basically only the reinforcing corner fittings 4A will be described.

The reinforcing corner piece 4A has a folded-back portion 4a. The folded-back part 4a is engaged with the rear part of the outer wall panel 3, and the position of the front-back direction and the position of the left-right direction of the reinforcement corner 4A is determined. In addition, the reinforcing corner piece 4A has a cut groove 4b. The notches 4b are configured to sandwich the bottom plate 5 in the left-right direction together with the notches 4b of the reinforcing corner fittings 4B and to engage with the bottom plate 5 .

Further, the reinforcing

corner pieces

4A, 4B include corner holes 4c. As will be described later, the back plate 6 is further provided with back plate holes 6a, and screws 8 can be inserted through the holes 4c, 6a and tightened to fix the back plate 6 to the reinforcing

corners

4A, 4B.

FIG. 3 is a flowchart of the assembly related to the reinforcing

corner pieces

4A, 4B of the refrigerator main body 2 . As shown in FIG. 3 , first, each of the reinforcing

corner pieces

4A and 4B is assembled to the outer wall panel 3 ( S1 ). Fig.4 (a) is a perspective view of the back surface of the refrigerator main body 2 after assembling each

reinforcement corner

4A, 4B. Fig. 4(b) is a partially enlarged view showing the circle A in Fig. 4(a). As shown in FIG. 4 , the corner reinforcement 4A is attached by hooking and engaging the folded portion 4a and the panel folded portion 3a provided behind the outer wall panel 3 . In FIG. 4, a broken line shows the boundary which abbreviate|omits a part of the component (in FIG. 4, the upper part of the refrigerator main body 2). The same applies to other figures.

Next, the base plate 5 is assembled (S2). FIG.5(a) is a perspective view of the back surface of the refrigerator main body 2 after assembling the bottom plate 5. FIG. Fig. 5(b) is a partially enlarged view showing circle B in Fig. 5(a). As shown in FIG. 5 , and as described above, the bottom plate 5 is disposed between the reinforcing corner fittings 4A and the reinforcing corner fittings 4B, engages with the notches 4b outward in the left-right direction, and is sandwiched and engaged between the notches 4b, The notch 4b is provided in each of the reinforcing

corner pieces

4A, 4B.

This engagement can be performed, for example, by temporarily expanding the left and right outer wall panels 3 to the outside in the left-right direction, disposing the rear part of the bottom plate 5 at a position corresponding to the notch 4b in the space created by this, and expanding the outer wall to the outside. The outer wall panels 3 are returned to the inside for configuration to the standard assembly position. The assembling method is not limited to this. For example, the base plate 5 may be arranged in front of the standard assembling position, and the base plate 5 may be configured so that the rear part of the base plate 5 is inserted into the notches 4b of the reinforcing corners 4A and 4B. 5 Move to the rear to thereby assemble. The cut groove 4b is formed so that the side facing each of the reinforcing

corner pieces

4A, 4B is substantially cut

glyph.

Moreover, the protrusion part 4ba which is bent so that it may extend frontward from the lower part of the cut groove 4b is provided in the cut groove 4b. The bottom plate 5 is provided on the protruding portion 4ba. By arranging the bottom plate 5 on the protruding portion 4ba in this manner, the bottom plate 5 can be arranged more stably than in a case where such a shape is not provided. Further, by providing the protruding portion 4ba, the size of the cut groove 4b can be adjusted more finely, and the position of the bottom plate 5 arranged in the cut groove 4b can be accurately maintained. Therefore, when the bottom plate 5 is sandwiched between the reinforcing

corner pieces

4A and 4B, it is configured not to be displaced in the up-down direction. Furthermore, even if the shape of the bottom plate 5 needs to be changed by changing the bending position and shape of the protrusion 4ba, the vertical dimension of the cut groove 4b can be appropriately and easily designed according to the shape of the bottom plate 5 .

After the base plate 5 is assembled, processing of the wire harness 9 and the like is performed ( S3 ). In this process, for example, the wiring harness 9, hose, etc., which are arranged on the back or lower part of the inner box 7, are arranged to pass through the bottom plate 5 to be arranged under the bottom plate 5. At this time, the base plate 5 is assembled by being sandwiched between the

corner reinforcements

4A and 4B without being tightened with screws or the like. Therefore, the

corner reinforcements

4A and 4B and the base plate 5 can be separated as necessary. This separation can be performed by moving each of the reinforcing

corner pieces

4A, 4B to the outside in the left-right direction, and can be easily separated during work. In addition, the re-attachment of the separated reinforcing

corner pieces

4A, 4B can be easily performed by aligning the vertical position of the bottom plate 5 with the notches 4b, and moving the respective left and right direction inner sides. Reinforcing

corner pieces

4A, 4B. Therefore, for example, when the process of S3 is performed, when the gap between the bottom plate 5 and the inner box 7 and the like is narrow, and the work of handling the wire harness 9 and the like is not easy to perform (for example, when the work is difficult or when the work needs to be done) When it takes a lot of time, etc.), the bottom plate 5 can be temporarily separated from each of the reinforcing

corner pieces

4A and 4B to increase the work space. Thereby, the workability of handling the wire harness 9 and the like can be improved.

Next, the back plate 6 is assembled (S4). FIG.6(a) is a perspective view of the back surface of the refrigerator main body 2 after assembling the back plate 6. FIG. Fig. 6(b) is a partially enlarged view showing circle C in Fig. 6(a). In the lower left and lower right portions of the back plate 6, back plate holes 6a are respectively provided. As described above, the corner holes 4c are included in each of the reinforcing

corner pieces

4A, 4B, the back plate holes 6a are aligned with the corner holes 4c, and the screws 8 are tightened into the holes 4c, 6a, thereby fixing the back plate 6 to each corner hole 4c. Reinforcing

corner pieces

4A, 4B.

The above is a flowchart of the assembly related to each of the reinforcing

corner pieces

4A and 4B of the refrigerator body 2 . Each of the reinforcing

corner pieces

4A and 4B of the present embodiment has many advantages compared with the conventional reinforcing corner pieces.

Hereinafter, an example of a reinforcing corner piece (hereinafter referred to as an old reinforcing corner piece) used in the past will be described. Like the refrigerator 1 of the present embodiment, the refrigerator 21 provided with the old reinforcing corners includes a refrigerator body 22 , an outer wall panel 23 , left and right old reinforcing corners 24A and 24B, a bottom plate 25 and a back plate 26 . The outer wall panels 23 are respectively provided on the left and right sides of the refrigerator main body 22 , and constitute the side walls of the refrigerator main body 22 . The inner box 27 is arranged inside each of the outer wall panels 23 . A foamed heat insulating material is filled between the outer wall panel 23 and the inner box 27, and each storage chamber is insulated from the outside air.

The bottom plate 25 is provided so as to cover at least a part of the inner case 27 on the lower side of the inner case 27 . In addition, the bottom plate 25 is formed so that the rear portion is disposed above the front portion when viewed in side view, and the rear end of the rear portion is configured to be disposed at the same position as the lower end of the back plate 26 described later. The bottom plate 25 is configured to be mounted to each of the old reinforcing corner pieces 24A, 24B at the rear thereof.

The back plate 26 is provided on the back surface of the refrigerator main body 22 and constitutes the rear wall of the refrigerator main body 22 . Like the outer wall panel 23 , the inner box 27 is arranged inside the back plate 26 (ie, in front of the back plate 26 ), and a foamed heat insulating material is filled between the back plate 26 and the inner box 27 .

FIG. 7 is a perspective view of the old reinforcing corner piece 24A, which is arranged at the lower part of the outer wall panel 23 on the left side of the refrigerator main body 22 . As shown in FIG. 7 , like the reinforcing corner fitting 4A, it is formed in a substantially L-shape in a side view. Moreover, the cross section is formed in a substantially L-shape. The old corner reinforcement 24B is configured to be substantially symmetrical in the left-right direction with respect to the old corner reinforcement 24A.

As shown in FIG. 7 , the old corner reinforcing piece 24A does not have a portion corresponding to the folded-back portion 4a of the reinforcing corner piece 4A, but has a first corner hole 24a. When the reinforcing corner piece 4A is assembled with respect to the outer wall panel 3 , the folded portion 4 a is engaged with the panel folded portion 3 a of the outer wall panel 3 . However, the old reinforcing corner piece 24A is shaped such that the old reinforcing corner piece 24A and the outer wall panel are fastened by passing the first screw 28a through the first corner hole 24a of the old reinforcing corner piece 24A and the panel hole 23a of the outer wall panel 23 23, thus fixed.

In addition, the old reinforcing corner piece 24A has the cutout groove 24b like the reinforcing corner piece 4A, but is cut out larger than the cutout groove 4b of the reinforcing corner piece 4A in the left-right direction. In addition, the old reinforcing corner pieces 24A, 24B include second corner holes 24c. As will be described later, the bottom plate 25 is provided with bottom plate holes 25a, and the back plate 26 is provided with back plate holes 26a. The second screws 28b can be inserted through the holes 24c, 25a, and 26a and tightened, thereby connecting the bottom plate 25 and the back plate. 26 is fixed to the old reinforcing corner pieces 24A, 24B. Further, above the cut groove 24b, there is a slit 24d into which a protrusion 25b of the bottom plate 25 described later is inserted.

Moreover, the side part of 4 A of reinforcement corner pieces and the side part of 24 A of old reinforcement corner pieces are formed in the shape which has a different structure. The side surface part of 24 A of old reinforcing corner pieces is comprised by the front-back direction side surface 24e and the longitudinal direction side surface 24f. In addition, the side surface part of 4 A of reinforcement corner pieces is also comprised from the front-back direction side surface 4e and the longitudinal direction side surface 4f similarly. As is apparent from FIG. 7 , the old reinforcing corner piece 24A is formed so that the front-rear direction side surface 24e is located inside the longitudinal direction side surface 24f in the left-right direction. On the other hand, as is apparent from FIG. 2 , the side portion of the reinforcing corner piece 4A is formed so that the front-rear direction side surface 4e is located outside the longitudinal direction side surface 4f in the left-right direction.

A sealing material is applied between each of the front-rear direction side surfaces 4e, 24e and the

outer wall panels

3, 23 so that no gap is created therebetween. If it is located inside the longitudinal direction side surface 24f like the front-rear direction side surface 24e of the old reinforcing corner 24A, the gap between the front-rear direction side surface 24e and the outer wall panel 23 is large, and sealing is difficult. On the other hand, the front-rear direction side surface 4e of the reinforcing corner piece 4A of the Example of this invention is located in the outer side of the longitudinal direction side surface 4f. Therefore, the gap between the front-rear direction side surface 4e and the outer wall panel 3 is smaller than that of the old reinforcing corner piece 24A, and sealing is easy.

FIG. 8 is a flowchart of the assembly related to the assembly of the old reinforcing corner piece 24A. As shown in FIG. 8 , first, the left and right old reinforcing corner pieces 24A, 24B are respectively arranged on the outer wall panel 23 (S21), and the old reinforcing corner pieces 24A, 24B and the outer wall panel 23 are fastened with the first screws 28a (S22) . Fig.9 (a) is a perspective view of the back surface of the refrigerator main body 22 after assembling the old reinforcing corner pieces 24A, 24B. FIG.9(b) is a partial enlarged view which shows the circle D of FIG.9(a). As shown in FIG. 9 , the old reinforcing corner pieces 24A are attached to the lower part and the rear of the outer wall panel 23 . The old reinforcing corner piece 24A is fixed together with the outer wall panel 23 by inserting the first screw 28a through the first corner hole 24a and tightening it. The outer wall panel 23 is provided with panel holes at corresponding positions.

Next, the base plate 25 is assembled (S23). FIG. 10( a ) is a perspective view of the rear surface of the refrigerator main body 22 with the bottom plate 25 assembled. Fig. 10(b) is a partially enlarged view showing the circle E in Fig. 10(a). The bottom plate 25 includes a bottom plate hole 25a for fastening with the second corner hole 24c and a protrusion 25b which can be inserted into the above-mentioned slit 24d. As shown in FIG. 10, the bottom plate 25 is arrange|positioned between the respective old reinforcing corner pieces 24A, 24B attached to the left and right outer wall panels 23. As shown in FIG. Then, this is inserted into the notched groove 24b provided in each of the old reinforcing corner pieces 24A and 24B, and the protrusion 25b is inserted into the slit 24d and engaged. The bottom plate hole 25a of the bottom plate 25 is configured to be arranged at a position corresponding to the second corner hole 24c by inserting the protruding portion 25b into the slit 24d.

After the base plate is assembled, processing of the wire harness 29 and the like is performed (S24). At this time, each of the left and right protrusions 25b is inserted into each of the slits 24d of the old corner reinforcements 24A, 24B, and therefore, unlike the bottom plate 5, the bottom plate 25 is substantially fixed to the old corner reinforcements 24A, 24B. Therefore, for example, if the gap between the bottom plate 25 and the inner box 27 is narrow when the step of S24 is performed, it is necessary to perform the processing of the wire harness 29 and the like in the state of the gap.

Next, the back plate 26 is assembled (S25). FIG. 11( a ) shows the lower back surface of the refrigerator main body 2 after the rear panel 26 is assembled. Fig. 11(b) is a partially enlarged view showing circle F in Fig. 11(a). The back plate 26 is provided with back plate holes 26a at its lower left and right lower portions. As mentioned above, each of the old reinforcing corner pieces 24A, 24B includes a second corner hole 24c, and the back plate hole 26a is aligned with each second corner hole 24c and each bottom plate hole 25a, and the second screw 28b is passed through the hole 24c, 25a, 26a and tighten, thereby fixing the back plate 26 together with the bottom plate 25 to each of the old reinforcing corner pieces 24A, 24B.

In this way, about the lower back surface of the refrigerator body 2 using the old reinforcing corner pieces 24A, 24B, the bottom plate hole 25a of the bottom plate 25 and the back plate hole 26a of the back plate 26 are aligned with the same second corner hole 24c, and a single screw to fasten the holes. Therefore, compared with the case of using different screws to fasten the bottom plate hole and the back plate hole to the reinforcing corner piece, although it can be fixed by tightening the screws once on the left and right, it is necessary to align the positions of the three holes, and resulting in an increase in working hours.

However, the lower back surface of the refrigerator body 2 using each of the

corner reinforcements

4A and 4B according to the embodiment of the present invention has a structure in which the bottom plate 5 is not fastened with screws, but the

corner reinforcements

4A and 4B are The notches 4b are clamped in the left-right direction to thereby fix; therefore, only the corner holes 4c and the back plate holes 6a are fastened by screws. Therefore, the holes can be easily aligned, and the work time can be reduced.

In addition, the first screws 28a are used to fasten each of the old reinforcing corner pieces 24A, 24B and the outer wall panel 23, but when each of the reinforcing

corner pieces

4A and 4B according to the embodiment of the present invention is used, it is possible to use the The folded-back portion 4a of each of the reinforcing

corner pieces

4A and 4B is engaged with the panel folded-back portion 3a of the outer wall panel 3, and is attached. Therefore, tightening of screws can be reduced, so that the cost of components can be reduced, and furthermore, the amount of assembling work can be reduced.

Furthermore, as is apparent from FIG. 7 , the cut grooves 24b provided in the old corner reinforcing piece 24A are cut over almost the entire width of the rear end face of the old reinforcing corner piece 24A in the left-right direction. However, the notch 4b of the reinforcing corner piece 4A according to the embodiment of the present invention is configured to hold the bottom plate 5 by a notch about half of the rear end surface of the reinforcing corner piece 4A in the left-right direction. Therefore, for example, when an impact due to a drop is applied to a refrigerator, the reinforcing corner piece 4A can have a shape that is more difficult to buckling than the old reinforcing corner piece 24A.

The present invention is not limited to the illustrated embodiments, and various improvements and design changes can be made without departing from the gist of the present invention.

Industrial Availability

As described above, according to the invention of the present disclosure, it is possible to provide a refrigerator that facilitates the assembly work of the refrigerator and reduces the amount of assembly work, and thus can be preferably used in the industrial field of such refrigerators.
