Description

[Detailed Description of the Invention] Woodworking relates to a refrigerator in which an inner box that forms the inner wall of a plurality of storage chambers in the main body and a partition wall that partitions them is integrally formed using a vacuum forming method from a single plastic sheet. ,
Concerning improvements to internal parts attachment parts.

Conventional examples of this type of refrigerator are shown in FIGS. 1 and 2.

In the figure, 1 is a refrigerator body with 2 independent freezer compartments and 3 refrigerator compartments, 4 is an outer box of this main body 1, and 5 is a plastic The inner box is integrally formed by vacuum forming a sheet,
Reference numeral 6 denotes a partition portion that divides the interior of the main body 1 into a freezing chamber 2 and a refrigerating chamber 3, and is formed integrally with the inner box 5. 7 is a cooler in which a refrigerant tube 9 is fixed to the lower surface of a metal plate 8 disposed at the bottom of the freezer compartment 2; It is a partition wall.

In this case, in order to fix internal parts such as the cooler 7 to the partition part 6, the plastic sheet of the partition part 6 must be thin.
Considering that it is impossible to screw the inner partition 6 to the bottom or ceiling surface from the viewpoint of strength, the mounting plate 11 is screwed to the partition wall 10 in advance as a reinforcing component as shown in FIG. Then, this partition wall 10 is inserted into the inner partition part 6, and a hole 5a is bored in the inner box 5, and internal parts such as the cooler 7 are mounted on the mounting plate 11 through the inner box 5. It was screwed into the screw hole 11a.

However, with this method, mounting the mounting plate 11 not only takes time and effort, but also involves vacuum forming the inner box together with the heat insulating plate while keeping the mounting plate in contact with the surface of the heat insulating material that serves as the partition wall of the hole 5a in the inner box 5. The inner box is integrally molded and sandwiched between the mounting plate inner box and the heat insulating board, and the inner box is recessed into the screw hole of the mounting plate, so that the mounting screw can be easily screwed into the screw hole. . Incidentally, the same elements as those in the conventional example described above are given the same reference numerals to simplify the explanation.

In the figure, 20 is a pre-formed heat insulating material that forms the main body of the partition wall, and a recess 20a is provided as shown in FIG.
Fit the mounting plate 21 into 0a.

The heat insulating material is set in a vacuum mold for the inner box 5, and the inner box 5 is formed from one plastic sheet by vacuum forming.

Then, as shown in FIG. 3, the plastic sheet comes into close contact with the heat insulating material 20 and is simultaneously drawn into the screw hole 21a of the mounting plate 21, forming a recess 21b shown in FIG. 5 in the screw hole 21a.

Next, the inner box 5 is assembled into the outer box 4, and the space between the inner box 5 and the outer box 40 is completely filled with a heat insulating material such as 14 polyurethane by injection foaming (FIG. 1). Therefore, as mentioned above, the cooler 7 is fixedly attached to the partition part 6 of the inner box 5, but the wall thickness of the partition part 6 is thin, and the screw hole 21a of the mounting plate 21 is inserted into the recess 2.
1b, the position of the screw hole 21a of the mounting plate 21 is known, and the plastic sheet can be easily broken using the set screw 22 with a sharp tip and screwed into the mounting plate 21.

In this embodiment, the cooler mounting on the soil surface of the partition wall is described in terms of the section, but the mounting of other internal parts on the bottom surface of the partition wall may also be applied to the section, and other parts may be installed in the section. By making the partition walls similar in structure to facilitate the installation of internal parts, there is no need to attach the mounting plate to the back of the inner box, and there is also no need to drill holes in the inner box for screw fixing. It provides a refrigerator cabinet H with high practical value.

In addition, since the insulation material is set in advance in the vacuum mold to form the entire inner box, if the insulation material and the inner box are made of the same material,
When the inner box is molded, it not only comes into close contact due to heat, but also adheres, and when screwed to the mounting plate, the periphery of the mounting plate is glued, making it stronger and yielding even better results.

Amended Specification 1, Title of Invention Method for manufacturing a refrigerator cabinet Manufacturing method as claimed in the claims. DETAILED DESCRIPTION OF THE INVENTION The present invention has an inner box having a tag and a mounting hole as a mark on the surface of the inner box. This article relates to a method for manufacturing a refrigerator cabinet that is integrally molded from two plastic sheets using a vacuum forming method. In particular, the present invention relates to improvements in the internal parts attachment section. Conventional examples of this type of refrigerator are shown in FIGS. 1 and 2. In the figure, (11 is the refrigerator body which has an independent freezer compartment (2) and refrigeration compartment (3) inside, (4) is the outer box of this main body (11), (5) is the freezer compartment (2) and The inner box (6) forms the inner wall of the refrigerator compartment (3) and is integrally formed by vacuum forming a plastic sheet. The partition part is formed integrally with the inner box (5). (7) is the freezer compartment (
2) A cooler in which a refrigerant pipe (9) is fixed to the lower surface of a metal plate (8) disposed at the bottom of the cooler. Alternatively, it is a plate-shaped partition wall made of a heat insulating material such as styrofoam inserted into the inner partition (6). In this case, parts inside the refrigerator such as the cooler (7) are separated from the inner partition (6).
K fixing k takes into consideration the fact that the plastic sheet of the middle partition (6) is thin and it is impossible to screw it to the bottom or ceiling of the middle partition (6) from the viewpoint of strength. As shown in Fig. 2, a mounting plate an as a reinforcing part is screwed in advance to the partition 11α, and this partition wall α is inserted into the inner partition part (6), and the inner box (5) K is set. Bakahole (5a)
was drilled and internal parts such as the cooler (7) were screwed through the inner box (5) into screw holes (11a) provided on the mounting plate. However, with this method, installing the mounting plate I is not a time-consuming task. It took a lot of effort to drill the hole (5a) in the inner box (5), and the workability was poor. The present invention aims to eliminate such drawbacks. For example, with the mounting plate in contact with the surface of the heat insulating material serving as a partition wall, the inner box and the heat insulating board are integrally molded using a molding method, and the mounting plate is sandwiched between the inner box and the heat insulating board. By invaginating the inner box into the screw holes of the attachment plate, the mounting screws can be easily screwed into the screw holes. Embodiments of the present invention will be described below based on FIGS. 3 to 5. Incidentally, the same elements as those in the conventional example described above are given the same reference numerals to simplify the explanation. In the figure, CB is a pre-formed heat insulating material that forms the main body of the partition wall, and is provided with a recess (2Oa) as shown in FIG. The recess (ZOa) VC mounting plate C! Insert υ. This heat insulating material was set in a vacuum forming mold for an inner box (51), and 8 boxes (
5) Form. Then, as shown in Figure 3, the plastic sheet comes into close contact with the heat insulating material ■, and at the same time the screw hole (21!L) on the top of the mounting plate is inserted.
The screw hole (zta) i (recess (Hb) shown in FIG. 5) is formed. Next, the inner box (5) is assembled into the outer box (41), and the inner box (51
Fill the space between the outer box (41) and the outer box (41) with a heat insulating material such as polyurethane by foaming (Fig. 1).Therefore, the partition part (6)K of the inner box (41) is fixed with the cooler (7) as described above. However, since the inner partition +61 has a thin wall and the screw hole (ZSa) of the mounting plate is a recess (21b)), the screw hole (21a) of the mounting plate - ) location is known, and. Using a set screw (2) with a sharp tip, you can easily tear the plastic sheet and insert the mounting plate I/C@. 9 In this embodiment, the cooler mounting section on the top surface of the partition wall has been described, but the mounting section on the bottom surface of the partition wall may also be applied to other parts of the refrigerator. It is also possible to make the partition walls that partition the chambers have a similar table configuration to facilitate the installation of internal parts. Since the present invention is constructed as described above, there is no need to attach a reinforcing mounting plate to the back of the inner box, and there is no need to drill holes in the inner box for fixing screws, making this a valuable refrigerator. cabinet. In addition, if the inner box is formed by setting the heat insulating material in the vacuum molding mold in advance, and the heat insulating material and the inner box are made of the same material, they will only stick together due to the heat during the molding of the inner box. If it is strong, the periphery of the mounting plate will be glued when it is screwed to the mounting plate, so if it is strong, the result will be even better.
