Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to mating wiring when optionally installing electric parts such as a heater in a refrigerator or the like.

BACKGROUND ART Wiring for connecting optional electrical components used in conventional refrigerators will be explained with reference to FIGS. 2 and 3.

Reference numeral 1 denotes a refrigerator body, which is composed of an outer box 2, an inner box 3, and a foamed heat insulating material 4 filled between both boxes 2 and 3. Reference numeral 5 denotes wiring constituting an electric circuit attached to the foam insulation material on the back surface of the inner box 3. Reference numeral 6 denotes a heater for compensating the temperature inside the refrigerator, which can be installed as an option. 7 is the tip of the wiring 5, and in normal use, the tip 7 is covered with a PVC pipe 8. When installing the optional refrigerator temperature compensation heater 6, the PVC pipe 8 is cut and the tip 7 of the wiring 5 and the heater 6 are connected.

Problems to be Solved by the Invention However, in the conventional structure, the tip 7 of the wiring 5 is covered with a PVC pipe 8 for insulation prevention and safety reasons, and then to prevent the PVC pipe 8 from coming off and to prevent moisture from entering. In order to prevent this, it is necessary to seal by heat welding, which increases the cost. Furthermore, when installing the optional heater 6, the PVC pipe 8 had to be cut, which was a time-consuming task.

The present invention aims to eliminate the conventional problems, reduce the number of parts, and improve installation workability.

Means for Solving the Problems In order to achieve the above-mentioned purpose, the present invention has a method of connecting a part of the wiring buried in the insulation material in a continuous loop to the inside of the refrigerator through a hole formed in the inner box. It has an extended part that is pulled out.

Function: Therefore, in the present invention, normally only a portion of the wiring is inside the refrigerator, and when installing an optional electrical component such as a heater, it is only necessary to connect to this wiring.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1. Structures that are the same as those of the prior art are designated by the same reference numerals, and detailed explanation thereof will be omitted.

In the figure, the wiring 5 attached to the back of the inner box 3
An extending portion 9 is provided which continuously extends in a loop shape from a hole 3-1 provided in the inner box 3 to the inner side of the refrigerator. The location is preferably a location behind the cooler 10 that cannot be easily touched during normal use. When installing the heater 6, the extending portion 9 of the wiring 5 is cut and connected together with the heater 6 using the connecting terminal 11.

When the heater 6 is not attached, the extension 9 constituting a part of the middle of the wiring 5 can be used normally as it is since the core wire is not exposed and there are no problems in terms of moisture intrusion, insulation and safety.

In the embodiment, the wiring is cut and attached, but a plurality of wires may be extended and the heater may be attached between the plurality of wires. In this case, a simple clamping process is sufficient without cutting.

Furthermore, since the extending portion 9 of the wiring 5 is normally hidden by the cooler 10, it does not affect the appearance.

Effects of the Invention As is clear from the above-mentioned embodiments, the present invention does not require the protection required when the tip of the wiring is extended in order to extend the wiring in the middle. Additionally, optional electrical components such as a heater can be easily installed.
