Jitsuzensho 56-172687

However, if screws are used to fix other parts to the reinforcing angle, the number of screws to be fastened increases and the assembly man-hours increase. Also, if multiple parts such as the bottom plate are fastened with the same screw, the number of screws can be reduced, but the position of the holes for passing the screws must be aligned for all parts, which increases the assembly man-hours. There is a possibility of connecting.

Further, if the bottom plate is fixed, it is not possible to secure a sufficiently large work space in the subsequent assembly process, which makes the work difficult, takes time, and may lead to an increase in assembly man-hours.

Therefore, an object of the present invention is to provide a refrigerator that facilitates the assembling work of the refrigerator and reduces the assembling man-hours.

The refrigerator according to the present invention is attached to the rear and lower portions of the refrigerator main body, the left and right outer wall panels constituting the side wall of the refrigerator main body, and the left and right outer wall panels so as to be arranged between the left and right outer wall panels. A refrigerator comprising a reinforcing angle, wherein the outer wall panel comprises a panel folded portion, the reinforcing angle comprises a folded portion, and the reinforcing angle is provided by engaging the panel folded portion with the folded portion. Is attached to the outer wall panel.

According to the present invention, it is possible to provide a refrigerator in which an outer wall panel and a reinforcing angle are attached without using screws. As a result, the number of screws used for fixing can be reduced, and the assembly man-hours can be reduced.

Further, the refrigerator further has a bottom plate configured to cover at least a part of the bottom of the refrigerator body, and each of the reinforcing angles has a notch on the side opposite to each reinforcing angle, and the bottom plate has a notch. , It is characterized in that it is configured to be attached by being sandwiched between the notches of each reinforcing angle.

According to the present invention, the reinforcing angle and the bottom plate can be attached without using screws. As a result, the number of screws used for fixing can be further reduced, and the assembly man-hours can be reduced.

Further, the bottom plate is characterized in that it can be removed from the notch of the reinforcing angle when the reinforcing angle is separated from the state where the bottom plate is attached to the left and right outside.

According to the present invention, when working in the gap between the bottom plate and other parts after assembling the bottom plate, if the gap is narrow and workability is poor, the respective reinforcing angles are separated outward in the left-right direction. Therefore, the bottom plate can be easily removed from the notch of the reinforcing angle to widen the work space. As a result, workability can be improved and assembly man-hours can be reduced.

Further, the refrigerator further has a back plate configured to cover at least a part of the back surface of the refrigerator body, and each of the reinforcing angles has an angle hole on the back surface, without the need for the bottom plate. It is characterized in that the back plate is fixed to the reinforcing angle by fastening the back plate hole provided in the back plate and the angle hole with a screw.

According to the present invention, when the same screw is passed through the hole of the bottom plate and the hole of the back plate and fixed to the reinforcing angle, it is not necessary to align the holes of the bottom plate. As a result, the work of aligning the holes of each component can be reduced, and the assembly man-hours can be reduced.

According to the invention according to the present disclosure, it is possible to provide a refrigerator that facilitates the assembling work of the refrigerator and reduces the assembling man-hours.

It is configured to be. The bottom plate 5 is configured to be attached to each of the reinforcing angles 4A and 4B at the rear portion.

The back plate 6 is provided on the back surface of the refrigerator main body 2 and constitutes the rear wall of the refrigerator main body 2. Similar to the outer wall panel 3, the inner box 7 is arranged inside the back plate 6 (that is, in front of the back plate 6), and the foam insulating material is filled between the back plate 6 and the inner box 7. There is.

FIG. 2 is a perspective view of the reinforcing angle 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 as to be substantially L-shaped when viewed from the side. Further, the cross section of the reinforcing angle 4A at the portion of the front-rear side surface 4e described later in the vertical-left-right plane and the cross section of the reinforcing angle 4A at the portion of the vertical side surface 4f described later in the front-rear-left-right plane are substantially L-shaped. It is formed so as to be. However, the present invention is not limited to this, and for example, each cross section may be formed to have a substantially U-shape. Since the reinforcing angle 4B is configured to be substantially symmetrical with respect to the reinforcing angle 4A in the left-right direction, basically only the reinforcing angle 4A will be described.

The reinforcing angle 4A has a folded-back portion 4a. The folded-back portion 4a engages with the rear portion of the outer wall panel 3 to determine the position in the front-rear direction and the position in the left-right direction of the reinforcing angle 4A. Further, the reinforcing angle 4A has a notch 4b. The notch 4b is configured to sandwich the bottom plate 5 in the left-right direction together with the notch 4b of the reinforcing angle 4B and engage with the bottom plate 5.

Further, each of the reinforcing angles 4A and 4B is provided with an angle hole 4c. As will be described later, the back plate 6 is also provided with a back plate hole 6a, and the screw 8 can be passed through the holes 4c and 6a and tightened, and the back plate 6 can be fixed to the reinforcing angles 4A and 4B.

FIG. 3 is a flowchart of assembly of the refrigerator main body 2 with respect to the reinforcing angles 4A and 4B. As shown in FIG. 3, first, the reinforcing angles 4A and 4B are assembled to the outer wall panel 3 (S1). FIG. 4A is a perspective view of the back surface of the refrigerator main body 2 after assembling the reinforcing angles 4A and 4B. FIG. 4B is a partially enlarged view showing the circle A in FIG. 4A. As shown in FIG. 4, the reinforcing angle 4A is attached by hooking and engaging the folded portion 4a with the panel folded portion 3a provided behind the outer wall panel 3. In FIG. 4, the alternate long and short dash line represents a boundary portion with a portion not shown when a part of the described components (the upper part of the refrigerator main body 2 in FIG. 4) is omitted. The same applies to other figures.

Next, the bottom plate 5 is assembled (S2). FIG. 5A is a perspective view of the back surface of the refrigerator main body 2 after the bottom plate 5 is assembled. 5 (b) is a partially enlarged view showing the circle B of FIG. 5 (a). As shown in FIG. 5, and as described above, the bottom plate 5 is arranged between the reinforcing angles 4A and the reinforcing angles 4B, and into the notches 4b provided in the respective reinforcing angles 4A and 4B. It is bitten outward in the left-right direction, sandwiched between the notches 4b, and engaged.

In this engagement, for example, the left and right outer wall panels 3 are temporarily expanded outward in the left-right direction, and in the space created thereby, the rear portion of the bottom plate 5 is arranged at a position corresponding to the notch 4b and expanded outward. This can be done by turning the outer wall panel 3 back in order to place it in the proper assembly position. The assembling method is not limited to this, for example, the bottom plate 5 is arranged in front of the regular assembling position, and the rear portion of the bottom plate 5 is inserted into the notch 4b of each reinforcing angle 4A, 4B. , The bottom plate 5 may be configured so that it can be assembled by moving it backward. The notch 4b is formed so that the side facing each of the reinforcing angles 4A and 4B has a substantially U-shape with a notch.

Further, the notch 4b is provided with a protruding portion 4ba formed by bending so as to extend forward from the lower portion of the notch 4b. The bottom plate 5 is placed on the protrusion 4ba. By arranging the bottom plate 5 on the protrusion 4ba in this way, the bottom plate 5 can be arranged more stably than in the case where such a shape is not provided. Further, by providing the protruding portion 4ba, the dimensions of the notch 4b can be adjusted more finely, and the bottom plate 5 arranged in the notch 4b can be accurately held. Therefore, when the bottom plate 5 is sandwiched between the reinforcing angles 4A and 4B, it is configured so as not to be displaced in the vertical direction. Further, even if it becomes necessary to change the shape of the bottom plate 5 by changing the bending position or shape of the protruding portion 4ba, the vertical dimension of the notch 4b can be appropriately and easily adjusted according to the shape of the bottom plate 5. Can be designed.

After assembling the bottom plate 5, the harness 9 and the like are processed (S3). In this process, for example, a harness 9 or a hose or the like arranged on the back or the lower part of the inner box 7 is passed through the bottom plate 5 and arranged in the lower part of the bottom plate 5. At this time, since the bottom plate 5 is assembled by being sandwiched between the reinforcing angles 4A and 4B and is not tightened with screws or the like, the reinforcing angles 4A and 4B and the bottom plate 5 should be separated as necessary. Can be done. The separation can be performed by moving the reinforcing angles 4A and 4B outward in the left-right direction, and the separation can be easily performed without requiring time for the work. Further, the reattachment of the separated reinforcing angles 4A and 4B can be performed by aligning the vertical position of the bottom plate 5 with the notch 4b and moving the reinforcing angles 4A and 4B inward in the left-right direction, respectively. It can be installed easily without taking time for work. Therefore, for example, when the process of S3 is performed, the gap between the bottom plate 5 and the inner box 7 or the like is narrow, and the workability of processing the harness 9 or the like is poor (for example, it is difficult to work or it takes time to work). In some cases, etc.), the bottom plate 5 can be temporarily separated from the reinforcing angles 4A and 4B to increase the work space. Thereby, the workability of processing the harness 9 and the like can be improved.

Next, the back plate 6 is assembled (S4). FIG. 6A is a perspective view of the back surface of the refrigerator main body 2 after the back plate 6 is assembled. FIG. 6B is a partially enlarged view showing the circle C in FIG. 6A. The back plate 6 is provided with a back plate hole 6a in each of the lower left and the lower right. As described above, the reinforcing angles 4A and 4B are provided with angle holes 4c, the back plate holes 6a are aligned with the angle holes 4c, the screws 8 are tightened to the holes 4c and 6a, and the back plate 6 is fastened to the reinforcing angles 4A. , 4B fixed.

The above is a flowchart of assembly of the refrigerator main body 2 with respect to the reinforcing angles 4A and 4B. Each of the reinforcing angles 4A and 4B according to the present embodiment has a plurality of advantages as compared with the conventional reinforcing angles.

Hereinafter, an example of a conventionally used reinforcing angle (hereinafter referred to as an old reinforcing angle) will be described. The refrigerator 21 provided with the old reinforcing angle includes a refrigerator main body 22, an outer wall panel 23, left and right old reinforcing angles 24A and 24B, a bottom plate 25, and a back plate 26, similarly to the refrigerator 1 according to the present embodiment. The outer wall panels 23 are provided on the left and right sides of the refrigerator main body 22, respectively, and form the side walls of the refrigerator main body 22. An inner box 27 is arranged inside each outer wall panel 23. An effervescent heat insulating material is filled between the outer wall panel 23 and the inner box 27 to insulate each storage room from the outside air.

The bottom plate 25 is provided below the inner box 27 so as to cover at least a part of the inner box 27. Further, the bottom plate 25 is formed so that the rear portion is arranged above the front portion when viewed from the side, and the rear end of the rear portion and the lower end of the back plate 26 described later are arranged at the same positions. It is configured to be. The bottom plate 25 is configured to be attached to the old reinforcing angles 24A and 24B at the rear portion.

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. Similar to the outer wall panel 23, the inner box 27 is arranged inside the back plate 26 (that is, in front of the back plate 26), and the foam insulating material is filled between the back plate 26 and the inner box 27. There is.

FIG. 7 is a perspective view of the old reinforcing angle 24A 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, similar to the reinforcing angle 4A, it is formed so as to have a substantially L shape in the side view. Further, the cross section is formed so as to be substantially L-shaped. The old reinforcing angle 24B is configured to be substantially symmetrical with respect to the old reinforcing angle 24A in the left-right direction.

As shown in FIG. 7, the old reinforcing angle 24A does not have a portion corresponding to the folded-back portion 4a of the reinforcing angle 4A, but instead has a first angle hole 24a. When the reinforcing angle 4A was assembled to the outer wall panel 3, the folded portion 4a was engaged with the panel folded portion 3a of the outer wall panel 3. However, the old reinforcing angle 24A is fixed by passing the first screw 28a through the first angle hole 24a of the old reinforcing angle 24A and the panel hole 23a of the outer wall panel 23 and fastening the old reinforcing angle 24A and the outer wall panel 23. It has a shape.

Further, the old reinforcing angle 24A has a notch 24b like the reinforcing angle 4A, but is notched larger in the left-right direction than the notch 4b of the reinforcing angle 4A. Further, the old reinforcing angles 24A and 24B are provided with a second angle hole 24c. As will be described later, the bottom plate 25 is provided with a bottom plate hole 25a, and the back plate 26 is provided with a back plate hole 26a. The second screw 28b is passed through the holes 24c, 25a, 26a and tightened, and the bottom plate 25 and the back plate are tightened. 26 can be fixed to the old reinforcing angles 24A and 24B. Further, above the notch 24b, there is a slit 24d into which the protruding portion 25b of the bottom plate 25, which will be described later, is inserted.

Further, the side surface portion of the reinforcing angle 4A and the side surface portion of the old reinforcing angle 24A are formed in a shape having different structures. The side surface portion of the old reinforcing angle 24A is composed of a front-rear side surface 24e and a vertical side surface 24f. Further, the side surface portion of the reinforcing angle 4A is also composed of the front-rear side surface 4e and the vertical side surface 4f. As is clear from FIG. 7, the old reinforcing angle 24A is formed so that the front-rear side surface 24e is positioned inward in the left-right direction from the vertical side surface 24f. On the other hand, the side surface portion of the reinforcing angle 4A is formed so that the front-rear side surface 4e is located outside the vertical side surface 4f in the left-right direction, as is clear from FIG.

A sealing material is applied between the front and rear side surfaces 4e and 24e and the outer wall panels 3 and 23 so that no gap is formed between them. If it is located inside the vertical side surface 24f like the front-rear side surface 24e of the old reinforcing angle 24A, the gap between the front-rear side surface 24e and the outer wall panel 23 becomes large, and it is difficult to seal. Become. On the other hand, the front-rear side surface 4e of the reinforcing angle 4A according to the embodiment of the present invention is located outside the vertical side surface 4f. Therefore, as compared with the old reinforcing angle 24A, the gap between the front-rear side surface 4e and the outer wall panel 3 is smaller, and sealing is easier.

FIG. 8 is an assembly flowchart relating to the assembly of the old reinforcing angle 24A. As shown in FIG. 8, first, the left and right old reinforcing angles 24A and 24B are arranged on the outer wall panel 23 (S21), and the old reinforcing angles 24A and 24B and the outer wall panel 23 are fastened to each other by using the first screw 28a. (S22). FIG. 9A is a perspective view of the back surface of the refrigerator main body 22 after assembling the old reinforcing angles 24A and 24B. 9 (b) is a partially enlarged view showing the circle D of FIG. 9 (a). As shown in FIG. 9, the old reinforcing angle 24A is attached to the lower part and the rear part of the outer wall panel 23. The old reinforcing angle 24A is fixed together with the outer wall panel 23 by fastening the first screw 28a through the first angle hole 24a. The outer wall panel 23 is provided with a panel hole at a corresponding position.

Next, the bottom plate 25 is assembled (S23). FIG. 10A is a perspective view of the back surface of the refrigerator main body 22 after the bottom plate 25 is assembled. 10 (b) is a partially enlarged view showing the circle E of FIG. 10 (a). The bottom plate 25 includes a bottom plate hole 25a for fastening together with the second angle hole 24c, and a protrusion 25b that can be inserted into the slit 24d described above. As shown in FIG. 10, the bottom plate 25 is arranged between the old reinforcing angles 24A and 24B attached to the left and right outer wall panels 23. Then, it is inserted into the notch 24b provided in each of the old reinforcing angles 24A and 24B, and the protruding portion 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 angle hole 24c by inserting the protruding portion 25b into the slit 24d.

After assembling the bottom plate, the harness 29 and the like are processed (S24). At this time, unlike the bottom plate 5, the bottom plate 25 is substantially fixed to the old reinforcing angles 24A and 24B because the left and right protruding portions 25b are inserted into the slits 24d of the old reinforcing angles 24A and 24B. Has been done. Therefore, for example, when the process of S24 is performed, if the gap between the bottom plate 25 and the inner box 27 is narrow, it is necessary to process the harness 29 or the like in the state of the gap.

Next, the back plate 26 is assembled (S25). FIG. 11A shows the lower part of the back surface of the refrigerator body 2 after the back plate 26 is assembled. 11 (b) is a partially enlarged view showing the circle F of FIG. 11 (a). The back plate 26 is provided with a back plate hole 26a in the lower left and lower right. As described above, each of the old reinforcing angles 24A and 24B is provided with a second angle hole 24c, the back plate hole 26a is aligned with each second angle hole 24c and each bottom plate hole 25a, and the second screw 28b is fitted with the hole 24c, It is tightened through 25a and 26a, and the back plate 26 is fixed to the old reinforcing angles 24A and 24B together with the bottom plate 25.

In this way, in the lower back surface of the refrigerator body 2 using the old reinforcing angles 24A and 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 angle hole 24c to form a single unit. Each hole was fastened with the screw of. As a result, compared to the case where the bottom plate hole and the back plate hole are fastened to the reinforcing angle using different screws, it can be fixed by fastening the screws once on the left and right, but it is necessary to align the positions of the three holes. This led to an increase in working time.

However, in the lower part of the back surface of the refrigerator body 2 using the reinforcing angles 4A and 4B according to the embodiment of the present invention, the bottom plate 5 is not fastened with screws, and the notches 4b of the reinforcing angles 4A and 4B are used in the left-right direction. Since the structure is such that it is fixed by sandwiching it, only the angle hole 4c and the back plate hole 6a are fastened with screws. Therefore, the holes can be easily aligned and the working time can be reduced.

Further, although the first screws 28a were used to fasten the old reinforcing angles 24A and 24B to the outer wall panel 23, when the reinforcing angles 4A and 4B according to the embodiment of the present invention are used, the respective reinforcing angles 4A and 4B are used. It can be attached by engaging the folded-back portion 4a of the reinforcing angles 4A and 4B with the panel folded-back portion 3a of the outer wall panel 3. Therefore, it is possible to reduce the number of screw fastenings, reduce the cost of parts, and reduce the number of assembly steps.

Further, as is clear from FIG. 7, the notch 24b provided in the old reinforcing angle 24A is cut out from the rear end surface of the old reinforcing angle 24A over almost the entire width in the left-right direction. However, the notch 4b of the reinforcing angle 4A according to the embodiment of the present invention is configured to hold the bottom plate 5 with a notch of about half in the left-right direction on the rear end surface of the reinforcing angle 4A. Therefore, for example, when an impact due to dropping is applied to the refrigerator, the reinforcing angle 4A can have a shape in which buckling is less likely to occur as compared with the old reinforcing angle 24A.

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

As described above, according to the invention according to the present disclosure, since it is possible to provide a refrigerator that facilitates the assembling work of the refrigerator and reduces the assembling man-hours, it can be suitably used in the industrial field of this type of refrigerator.
