プの熱交換効率向上は目ざましいものである。Conventional configurations and their problems In recent years, refrigerators have been rapidly moving toward lower power consumption due to rising electricity bills due to soaring energy costs, etc., and the cooling performance of refrigerators has been forced to become more efficient. In addition, the appearance of refrigerators is becoming more colorful and simple, and most models have heat dissipation pipes and cooling pipes embedded within the insulation material of the insulating box, improving the heat exchange efficiency of heat dissipation pipes and cooling pipes. is remarkable.
以下、図面を参照しながら、上術したような従
来の断熱箱体の断熱材内に埋設された冷却パイプ
を有する冷蔵庫について説明する。 Hereinafter, with reference to the drawings, a refrigerator having a cooling pipe embedded in the heat insulating material of the conventional heat insulating box as described above will be described.

する。 The function of the cooling pipe embedded in the heat insulating material of the heat insulating box configured as above will be explained below. The refrigerant compressed by the compressor flows from the well-known heat dissipation pipe of the refrigeration cycle to the cooling pipe 4 through a capillary reach tube (none of which is shown), expands and vaporizes in the cooling pipe 4, and is cooled. The heat is conducted through the aluminum foil tape 5 and transferred to the inner box 2. Further, although the contact area with the cooling pipe 4 is small, it is directly conducted to the inner box 2 and cools the inside of the refrigerator.

脂製の内箱２が、第２図の内箱２′部のように変
形し外観をそこなうという欠点を有していた。 However, in the above configuration, since the cooling pipe 4 is attached to the inner box 2 with the aluminum foil tape 5, there is a gap between the aluminum foil tape 5, the cooling pipe 4, and the inner box 2.
6 is formed, so the cooling pipe 4 is formed,
When the inside of the refrigerator is cooled, the space 6 contracts, causing the inner box 2 made of synthetic resin to deform as shown in the inner box 2' portion of FIG. 2, which impairs its appearance.
発明の目的
本発明は、上記従来の欠点を除去するものであ

形することがなくなる。Structure of the Invention In order to achieve this object, the refrigerator of the present invention has the following features:
An outer box, an inner box made of synthetic resin that is spaced apart from the outer box, a foam insulation material that is injected and foamed between these two boxes, and a cooling pipe that is arranged on the foam insulation material side of the inner box. , an aluminum foil tape that fixes the cooling pipe to the inner box, and a self-adhesive plastic resin that is attached between the inner box and the cooling pipe and softens and deforms due to the reaction heat and foaming pressure generated during the injection and foaming process. The structure is equipped with the following features. According to the above structure, when urethane is injected and foamed, the self-adhesive plastic resin is softened by the reaction heat and foaming pressure.
In addition, the foaming pressure of the foam insulation material pulls the aluminum foil tape and the cooling pipe toward the inner box, and at the same time, the space between them is filled with self-adhesive plastic resin, so the cooling pipe and the inside of the refrigerator are cooled. The inner box will not be deformed even if the inner box is removed.

つけて内箱２へ固定するものである。 FIG. 3 shows a cooling pipe fixed to the inner box of the present invention with aluminum foil tape. That is, the cooling pipe 4 is arranged in an inner box 2 made of synthetic resin via a self-adhesive plastic resin 7 such as adhesive butyl rubber,
In order to prevent the urethane 3 from entering from above and to improve heat conduction to the inner box 2, an aluminum foil tape 5 is pasted and fixed to the inner box 2.
以上のように構成された冷却パイプを冷えた冷
蔵庫について、以下第４図により説明する。 A refrigerator having a cooling pipe configured as described above will be explained below with reference to FIG. 4.
前述の第３図のような構成をすることにより、
外箱１との間にウレタン３を注入発泡すると反応

間〓６はウレタン３の発泡前より大幅に縮小され
る。 By configuring as shown in Figure 3 above,
When the urethane 3 is injected and foamed between the outer box 1 and the urethane 3, the reaction heat becomes approximately 70°C, and the foaming pressure of the urethane (approximately
The self-adhesive plastic resin 7 softened by 0.2Kg/cm 2 ) is attached to the aluminum foil tape 5 and the cooling pipe 4 in the space 6 formed between the inner box 2 , the cooling pipe 4 and the aluminum foil tape 5 . is pressed toward the inner box 2 side, so it goes around the cooling pipe 4 evenly,
The distance 6 is significantly reduced compared to before the foaming of the urethane 3.
なお、アルミ箔テープ５は、単なるアルミ箔と
し自己粘着性可塑性樹脂７により固定してもよ
い。 Note that the aluminum foil tape 5 may be a simple aluminum foil and may be fixed with a self-adhesive plastic resin 7.
これにより、内箱２と冷却パイプ４とアルミ箔

却されることによる自己粘着性可塑性樹脂の剛性
向上もあり微々たるものとなり、内箱２の変形を
防止できるものである。 As a result, the shrinkage of the gap 6 formed between the inner box 2, the cooling pipe 4, and the aluminum foil tape 5 during cooling becomes negligible due to the improvement in the rigidity of the self-adhesive plastic resin as it cools. This can prevent the deformation of No. 2.
