Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention is a device in which the outer box back plate and the outer box bottom plate are manufactured as separate parts, and a structure for temporarily fixing them is provided. Regarding an improved refrigerator.

(Prior art) In conventional refrigerators in which the outer box back plate and the outer box bottom plate are manufactured as separate parts, the two are fixed with screws or rivets, or temporarily fixed with tape, and after they are fixed. A foamed insulation material is injected and solidified between the outer box and the inner box.

(Problems in the background art) However, when screws or rivets are used, the heads of the screws or rivets are visible in appearance, resulting in poor design, and it is difficult to fix the case when tightening the outer case back plate and the outer case bottom plate. This has the disadvantage that the back plate of the outer box is easily deformed because it is difficult to attach, and the number of parts increases because screws and rivets are required. Furthermore, temporary fixing with tape has the disadvantage that the process is troublesome and the reliability of fixing is poor.

Therefore, an object of the present invention is to provide a refrigerator that can easily and reliably temporarily fix the outer case back plate and the outer case bottom plate, has a low cost without increasing the number of parts, and has an excellent appearance. is to provide.

[Structure of the invention] (Means for solving the problem) The present invention provides a bushing for removably supporting a dew pan on the outer case back plate by temporarily fixing the outer case bottom plate to the outer case back plate. is fixed, and after temporary fixation, a foamed heat insulating material is injected and solidified between the outer box and the inner box.

(Function) According to the above means, the outer case bottom plate is temporarily fixed to the outer case back plate by using the bushing for removably supporting the dew pan, so the temporary fixation can be easily and reliably performed. Compared to screwing and riveting, there is no increase in the number of parts, so the cost is low, and since the heads of screws and rivets are not visible, the appearance is excellent.

(Example) An example of the present invention will be described below with reference to the drawings. In Figure 2, 1 is the refrigerator body;
It is formed by injecting and solidifying a foamed insulation material 4 between the outer box 2 and the inner box 3 while the inner box 3 is housed in the outer box 2. A freezing compartment 5 and a refrigerating compartment 6 are provided on the front side. Doors 7 and 8 are provided to open and close the outer box 2, respectively, and a compressor 9 is installed at the rear lower part of the outer box 2.

The outer box 2 and the dew pan 10 will be described in detail below with reference to FIGS. 1 and 3. At the lower end of the outer box back plate 11, there is a bent part 12 bent forward into an L-shape.
is provided, and a hook portion 12a is provided at the front end of the bent portion 12.
is formed by bending. A hook portion 13a bent downward is formed at the rear end portion of the outer box bottom plate 13. On the other hand, 14 is a plastic bushing having an insertion hole 15 formed at its rear end, and a flange 14a is provided at its tip. This bushing 14 is attached to the bent part 12 of the outer case back plate 11 on the outer case bottom plate 13.
When the hook part 13a is engaged and then fitted into the hole 16 provided in the outer case back plate 11, the outer case bottom plate 13 is pressed in the direction of the bent part 12 of the outer case back plate 11 with its outer surface. As a result, the outer case bottom plate 13 is temporarily fixed to the outer case back plate 11. When the bush 14 is fitted into the hole 16, the tapered protrusion 14b on the outer surface engages with the inner surface of the outer case back plate 11, thereby preventing the bush from coming off. On the other hand, foam insulation material 4
As described above, the outer box bottom plate 13 is connected to the outer box back plate 11.
It is formed by injecting an undiluted solution between the outer box 2 and the inner box 3 and foaming and solidifying them after the outer box 2 and the inner box 3 are temporarily fixed. Further, the dew pan 10 is manufactured by integral molding of plastic, and a convex portion 17 having an insertion convex portion 17a is integrally molded at the rear end thereof.
This dew pan 10 is removably set above the compressor 9 by removably fitting the insertion convex portion 17a into the insertion hole 15 of the bush 14, and the dew pan 10 is removably set above the compressor 9. of defrosting water is stored.

According to the above configuration, the bush 14 that removably supports the dew pan 10 is fitted into the hole 16 of the outer case back plate 11, and the outer surface of the bush 14 is brought into pressure contact with the outer case bottom plate 13, thereby temporarily fixing the two. Because of this, temporary fixation is easier and more reliable than conventional screw or riveted fixings, and there is no increase in the number of parts, resulting in lower costs, and the head is not visible on the outside. Therefore, it has an excellent appearance. Moreover, the process is extremely simple compared to conventional tape fixing, and the reliability for temporary fixing is also excellent.

Note that since the bush 14 has a flange 14a at its tip, the bush 14 can be removed after the foamed heat insulating material 4 is formed.
This is reliably prevented from slipping out of the hole 16.

[Effects of the invention] As is clear from the above explanation, the present invention temporarily fixes the outer case back plate and the outer case bottom plate using a bushing for supporting the dew pan. This can be done reliably and there is no increase in the number of parts, so it is possible to provide a refrigerator that is low cost and has an excellent appearance.
