Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for fixing a cooler pipe of a refrigerator to a necessary freezer compartment of an inner box.

Conventionally, the cooler pipe is attached and fixed to the freezer compartment of the inner box of the refrigerator main body by meandering along the outer wall surface of the freezer compartment 1a of the vacuum-formed synthetic resin inner box 1, as shown in Fig. 1. The cooler pipe 2 bent into a shape is brought into contact with the cooler pipe 2, and after positioning the cooler pipe 2 with tape or the like, the entire area of the cooler pipe 2 is covered with an aluminum foil tape 3 coated with an adhesive or agent. Attach the cooler pipe 2 to the freezer compartment 1 of the inner box 1.
It was fixed at a.

In the figure, reference numeral 4 indicates an outer box made of a steel plate, and reference numeral 5 indicates a foam insulation material filled in the space between the outer box 4 and the inner box 1.

However, with this structure, it takes a lot of time to attach the aluminum foil tape to the uneven surface, and the cooler pipe is fixed to the flat inner box surface, which has the disadvantage of poor heat conduction. Ta.

The present invention was made to improve the above defects,
Therefore, the first objective is to provide a method for fixing a cooler pipe for a refrigerator, which can significantly improve workability and achieve work automation, and also has a good heat conduction effect and is strong.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 5. First, in Fig. 2, 6 is the refrigerator body, 7 is the outer box made of steel plate, 8 is the inner box made of vacuum-formed synthetic resin, and 9 is the cooler pipe that is part of the refrigeration cycle. . Specifically, as shown in FIG. 3, this cooler pipe 9 is bent in a meandering manner and formed in a series, and is fixed by biting into the freezer compartment 8a of the vacuum-formed inner box 8 as shown in the same figure. ing. In addition, 10 in the figure is an aluminum foil tape or synthetic resin film pasted to cover the entire area of the cooler pipe 9;
1 is a foamed heat insulating material filled in the space between the outer box 7 and the inner box 8. Next, to explain the steps of the method for fixing the cooler pipe of a refrigerator according to the present invention, as shown in FIG. An arcuate groove 12b is provided in a meandering manner, and a vacuum hole 12C is provided for attaching and detaching the cooler pipe 9 to the arcuate groove 12b.
is drilled.

The inner box 8 is formed by vacuum forming. That is,
As shown in the same figure, the cooler pipe 9 is attached to the arcuate groove 12b of the freezer compartment forming part 12a of the vacuum forming mold 12, and is attracted and arranged by the vacuum suction of the multiple vacuum holes 12C.Next, ”
A synthetic resin sheet 13 is temporarily placed on the L side of the vacuum forming mold 12 with a gap left therebetween. Then, the sheet 13 is heated and softened by a forming process of a well-known vacuum forming method, and forming is started in a flexible state. That is, the sheet 13 is sucked and formed along the surface of the vacuum mold 12 by vacuum suction from a large number of vacuum holes (not shown) provided in advance on the surface of the vacuum mold 12 . At this time, the cooler pipe 9 is disposed in the vacuum mold 12 and depicts a part of the vacuum mold 12.

Therefore, the notebook 13 is heated and softened along the shape of the vacuum mold 12 and the cooler pipe 9 that the sheet 13 comes into contact with.
The freezer compartment 8a of the inner box 8 is adsorbed according to its cross-sectional shape.
The cooler pipe 9 bites into and is fixed. The entire area of the cooler vibe 9 is covered and fixed with an aluminum foil tape or a synthetic resin film 10.

This completes the installation and fixing of the cooler pipe 9. Therefore, according to this method, compared to the conventional method, work such as positioning tape is not necessary (aluminum foil tape or By pasting the synthetic resin film, the surface becomes flat, which significantly improves work efficiency and can also achieve work automation, and also provides a method for fixing refrigerator cooler pipes that has good heat conduction and is strong. It is something.

As described below, the present invention includes a serpentine bent condenser pipe removably disposed in the freezer compartment molding part of a vacuum molding mold for vacuum forming an inner box, and the condenser pipe and the vacuum Temporarily install a synthetic resin sheet with a gap above the mold,
The sheet No. 111f is heated and softened by the forming process of the vacuum forming method, and the cooler pipe is inserted into the frozen part of the vacuum-formed inner box by vacuum suction and fixed, and then aluminum foil tape or This is a synthetic resin film that is pasted over the entire area of the cooler pipe, allowing the cooler pipe to be easily and securely installed in the freezer compartment of the inner box. The present invention provides a method for fixing a refrigerator cooler pipe with good heat conduction effect.

[Brief explanation of the drawing]

Fig. 1 is a partial vertical sectional view of a refrigerator main body showing a conventional method of fixing a cooler pipe of a refrigerator, and Figs. 2 to 5 show an embodiment of the present invention. 3 is a vertical sectional view of the main part, and FIGS. 4 and 5 are explanatory diagrams showing the state before and after the vacuum forming process with the cooler pipe attached to the vacuum forming mold. be.
