Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention is a side plate of an outer box for a refrigerator that has an improved structure in which a reinforcing plate is superimposed and fixed to the lower flange of the main lower part of the side plate. Regarding.

(Prior art) Conventionally, the outer box for a refrigerator has been made of left and right side panels,
There is a device in which the top plate, bottom plate, and rear plate are manufactured separately and assembled together. Since it is necessary to attach a compressor support base for supporting the heavy compressor to the lower side of the side plate of such a refrigerator outer box, a lower part formed by bending is attached to the lower side of the main part of the side plate. A reinforcing plate having a substantially L-shaped cross section is superimposed on the flange, and this reinforcing plate is fixed to the lower flange with screws.

(Problem to be solved by the invention) However, in the above configuration, the reinforcing plate is fixed to the lower flange of the main part of the side plate with screws, which increases the number of parts and requires tightening tools such as a screwdriver. However, it had the disadvantage of poor assembly workability.

Therefore, the purpose of the present invention is to eliminate the need for screw tightening work, reduce the number of parts, and eliminate the need for tightening tools, thereby improving assembly workability and, moreover, increasing the fixing strength of the reinforcing plate. To provide side panels for refrigerator outer boxes.

[Structure of the invention] (Means for solving the problem) The side plate of the outer box for a refrigerator of the present invention is formed by bending one side of the main part of the side plate, and protrudes inward perpendicularly to the main part of the side plate. A first flange having a vertical part and a folded part that is folded back from the vertical part and becomes substantially parallel to the vertical part, and a second flange formed by bending and protruding inward on the other side of the main part of the side plate. established,
A reinforcing plate having a substantially L-shaped cross section is provided which overlaps the lower flange formed on the lower side of the main part of the side plate, and a vertical part and a folded part at the lower end of the first flange are provided at one end of the reinforcing plate. A bent piece is provided to be inserted between the reinforcing plates, and an engaging piece is provided at the other end of the reinforcing plate to abut on the lower end surface of the second flange. The other end of the bent portion formed into a substantially L-shape is inserted and fitted between the second flange and the main portion of the side plate, and the reinforcing plate is inserted into the lower end of the first flange. It is characterized in that it is configured to be sandwiched and fixed between the end face and the lower end end face of the second flange and the lower flange.

(Function) Insert the bent piece of the reinforcing plate between the vertical part and the folded part at the lower end of the first flange, and engage the engaging piece with the end surface of the lower end of the second flange. This allows it to be fixed to the lower flange of the main part of the side plate without screwing. When the reinforcing plate is fixed to the main part of the side plate, the reinforcing plate is fixed between the lower end face of the first flange, the lower end face of the second flange, and the lower flange. Therefore, the reinforcing plate does not move vertically. At the same time, the bent piece of the reinforcing plate is inserted between the vertical part and the folded part at the lower end of the first flange, and the other end of the bent part is inserted between the second flange and the main part of the side plate. Since the reinforcing plate is inserted and fitted in between, the reinforcing plate does not move laterally.

(Embodiment) Hereinafter, a first embodiment of the present invention will be explained with reference to FIGS. 1 to 4.
The figure shows the bottom end upside down.

In FIG. 1, reference numeral 1 denotes a main part of a side plate made of an iron plate having an overall rectangular shape, which constitutes a part of an outer box for a refrigerator. This side plate main portion 1 has a front flange 2, which is a first flange, formed by bending on the front side, which is one side, and a second flange, which is formed by bending, on the other side, the rear side. It has a rear flange 3 and a lower flange 4 formed on the lower side by being bent inward at right angles to the rear flange 3. Here, the front flange 2 includes a vertical part 2a that is perpendicular to the side plate main part 1 and projects inward, a folded part 2b that is folded back from this and becomes substantially parallel to this, and a folded part 2b that is folded back from this folded part 2b. It consists of a receiving folded portion 2c forming a substantially wedge-shaped front receiving recess. Further, the rear flange 3 is folded back to the side plate main portion 1 to form a first folded portion 3a that is substantially parallel to the main portion 1, and is folded back from the first folded portion 3a to form a substantially wedge-shaped rear receiving recess. It consists of a second folded part 3b and a vertical part 3c which is bent from this folded part 3b and perpendicular to the side plate main part 1.

Now, reference numeral 5 denotes a reinforcing plate having a substantially L-shaped cross section which overlaps with the lower flange 4 of the main side plate part 1, and a bent piece part 6 is provided at a right angle to the front end thereof.
This bent piece portion 6 is inserted between the vertical portion 2a and the folded portion 2b at the lower end portion (the upper end portion in the figure) of the front flange 2. Also,
The other end of the reinforcing plate 5 is a rear end portion that corresponds to the shape of the rear receiving recess formed by the first and second folded portions 3a and 3b of the rear flange 3, and has a first and second folded portion 3a. , 3b is provided, and the engaging piece 7 has a recess 7a for pinching the second flange 3. The engaging piece 7 comes into contact with the lower end surface of the second flange 3. Reference numeral 8 denotes a bent portion having a substantially L-shaped cross section on the side portion of the reinforcing plate 5, which is in contact with the inner surface of the lower side portion of the side plate main portion 1, and the other end, the rear end, is in contact with the rear flange 3. It is adapted to be inserted and fitted between the first folded portion 3a and the inner surface of the side plate main portion 1. Reference numeral 9 denotes a sealing member for the foam heat insulating material, which is attached so as to cover the bent piece 6 of the reinforcing plate 5 and a part of the bent part 8 in the vicinity thereof.

The case of attaching the reinforcing plate 5 to the side plate main portion 1 will be explained with reference also to FIGS. 2 to 4. First, the bent piece part 6 of the reinforcing plate 5 is inserted together with the seal member 9 between the vertical part 2a and the folded part 2b at the lower end of the front flange 2 of the side plate main part 1. Along with this, the recess 7 of the engagement piece 7 of the reinforcing plate 5
The first and second folded portions 3a and 3b in the vicinity of the lower end of the rear flange 3 of the side plate main portion 1 are inserted into the inner portion a, and are compressed and deformed by compression. In this state, when the rear side of the reinforcing plate 5 is moved in the direction of arrow A in FIG.
overlaps and is fixed to the lower flange 4 of the side plate main portion 1. At this time, the reinforcing plate 5 has the first and second folded portions 3a and 3b indicated by broken lines (Figs. 3 and 4).
The end surface of the engagement piece 7 engages with the upper surface (the back surface in the figure) of the engaging piece 7 as shown in the figure.
Also, since the bent portion 8 engages with the first folded portion 3a, movement in the direction of arrow B in FIG. 3 is restricted. Further, since the reinforcing plate 5 has the bent piece 6 inserted between the vertical part 2a and the folded part 2b of the front flange 2, movement in the opposite direction of arrow A and in the direction of arrow B is also limited to the middle part. is overlapped with the lower flange 4, so movement in the direction of arrow A is restricted.

Then, two side plates consisting of the side plate main part 1 and the reinforcing plate 5 are provided on the left and right sides, and a rear plate is attached to the rear portions of these, that is, the first and second folded portions 3a, 3b of the rear flange 3. Both side flanges of the rear plate (not shown) are inserted into the rear receiving recess formed by the box, a top plate (not shown) is attached to the upper part, and a bottom plate (not shown) is attached to the lower part to form an outer box. A plastic inner box (not shown) in which a refrigerator compartment and a freezer compartment are integrally molded is arranged inside such an outer box, and the flange formed at the front opening edge of the inner box is connected to the front flange 2 of the side plate. It is inserted into the front receiving recess formed by the folded part 2b and the receiving folded part 2c, and then a foamable heat insulating material is foam-filled between the outer box and the inner box. Thereafter, a compressor support stand for supporting a heavy compressor is attached to the reinforcing plate 5 of the side plate.

According to this embodiment having such a configuration, the following effects can be obtained. That is, since the bending piece 6 is provided at the front end of the reinforcing plate 5 and the engaging piece 7 is provided at the rear end, the bending piece 6 is attached to the vertical part at the lower end of the front flange 2. The reinforcing plate 5 is attached to the lower flange 4 of the side plate main part 1 by a simple operation of inserting it between the folded part 2a and the folded part 2b and engaging the engaging piece part 7 with the lower end face of the rear flange 3. Can be fixed by polymerization. This results in
Unlike the conventional method, it is possible to eliminate the need for screw tightening work, thereby reducing the number of parts and eliminating the need for a tightening tool, thereby improving assembly workability. In addition, since the bent piece 6 of the reinforcing plate 5 is inserted between the vertical part 2a and the folded part 2b at the lower end of the front flange 2, the strength of the lower side of the main part 1 of the side plate is reduced accordingly. You can improve. Furthermore, when conventionally foaming the foaming insulation material, the foaming insulation material enters the recess formed by the vertical part and the folded part of the front flange of the main part of the side plate, causing the foaming insulation material to enter the lower end of the front flange and the reinforcing plate. In order to prevent leakage from the contact area, a sealing member was installed along the entire length of the front flange in the vertical direction to close the opening of the recess formed by the vertical part and the folded part of the front flange. A simple configuration in which the member 9 is attached to a part of the bent piece part 6 and part of the bent part 8 of the reinforcing plate 5 can prevent leakage of the heat insulating material when the foamable heat insulating material is foamed. In addition, the bent piece part 6 of the reinforcing plate 5 is connected to the vertical part 2a at the lower end of the front flange 2 and the folded part 2.
Since the front end portion of the reinforcing plate 5 is inserted between the vertical portion 2a of the front flange 2, there is no possibility that the front end portion of the reinforcing plate 5 protrudes forward from the outer surface of the vertical portion 2a of the front flange 2.

5 to 7 show a second embodiment of the present invention, and only the differences from the first embodiment will be explained. Reference numeral 10 denotes a bent piece provided at the front end of the reinforcing plate 5 in place of the bent piece 6, which projects slightly forward and is formed to be slightly narrow. 11
is an engagement piece portion provided on the reinforcing plate 5 in place of the engagement piece portion 8. In this second embodiment as well, the procedure for attaching the reinforcing plate 5 to the side plate main portion 1 is the same as that in the first embodiment.
This embodiment is similar to that of the first embodiment, and substantially the same effects as those of the first embodiment can be obtained.

[Effects of the invention] As is clear from the above description, the present invention provides a reinforcing plate with a substantially L-shaped cross section that overlaps the lower flange formed on the lower side of the main part of the side plate, and a A bent piece part is provided at the lower end of the first flange of the main side plate part to be inserted between the vertical part and the folded part, and the other end of the reinforcing part is provided at the end surface of the lower end part of the second flange of the main part of the side plate. An engaging piece portion that comes into contact is provided, and the other end portion of the bent portion, which is bent into a substantially L shape on the side portion of the reinforcing plate, is inserted and fitted between the second flange and the main portion of the side plate. At the same time, the reinforcing plate
Since the structure is such that the lower flange is sandwiched and fixed between the lower end face of the first flange and the lower end face of the second flange, it is possible to eliminate the need for screw fastening work, reduce the number of parts, and tighten the parts. This has the excellent effect of eliminating the need for additional tools, improving assembly workability, and increasing the fixing strength of the reinforcing plate.
