Description

【発明の詳細な説明】 産業上の利用分野 本発明は食品等を貯蔵する冷蔵庫に関する。[Detailed description of the invention] Industrial applications The present invention relates to a refrigerator for storing foods and the like.

従来の技術 近年、冷蔵庫は背面が平滑化されこのことに伴って冷却
器は断熱材の発泡以前に内箱に取付けられ、その冷媒配
管も断熱材中に埋設されている。BACKGROUND OF THE INVENTION In recent years, the back surface of refrigerators has become smoother, and as a result, the cooler is attached to the inner box before foaming of the insulation material, and its refrigerant piping is also buried in the insulation material.

る如く配設されている。An example of a conventional refrigerator will be described below with reference to the drawings. FIGS. 4 and 5 show how to install a conventional refrigerator tubular cooler. In FIGS. 4 and 5, 1 is the outer box. 2 is an inner box, with a protrusion 3 on the back wall 6.
has been established. 4 is a foamed heat insulating material filled in both boxes 1 and 2-. 5 is attached to the inner box 2 before the foamed heat insulating material 4 is injected and foamed using a tubular cooler, and is disposed so as to abut and cross the top surface of the protrusion 3.

美観をそこねるという問題があった。これは次の理由に
よる。Problems to be Solved by the Invention However, in the above structure, the protrusion 3 and wall surface 6 of the inner box 2 bulge toward the inside of the chamber due to the foaming pressure of the foam insulation material 4, resulting in a reduction in the space for cold air convection and a decrease in the wall surface 6. There was a problem of damage or deterioration of the aesthetic appearance. This is due to the following reason.

つまり、管状冷却器５は突起３の頂面上を部分的に当接
し且つ蛇行通過しておシ、内箱２に対する管状冷却器６

することができない為である。That is, the tubular cooler 5 partially abuts on the top surface of the protrusion 3 and passes in a meandering manner.
The position of is not determined accurately, and there are large variations in the vertical and horizontal directions. This is because the foaming jig cannot be brought into contact with the projected area of the tubular cooler 5, the projections 3, and the wall surface 6 to foam the heat insulating material.

そこで本発明は上記問題点に鑑み、管状冷却器を取付け
た内箱の壁面の変形、破損、不体裁を防止する冷蔵庫を
提供するものである。In view of the above-mentioned problems, the present invention provides a refrigerator that prevents deformation, damage, and unsightliness of the wall surface of the inner box to which the tubular cooler is attached.

且つ乗せて取付けるという構成を備えたものである。Means for Solving the Problem In order to solve the above problems, the refrigerator of the present invention has a structure in which the bent portion of the tubular cooler is hooked onto and mounted on a stepped protrusion provided on the wall of the inner box. It is something that

ができるのである。Effect of the Invention With the above-described configuration, the tubular cooler can always be installed in an accurate position with respect to the inner box without any vertical or horizontal variation before foaming of the heat insulating material. By inserting the foaming jig into the stepped protrusion and the wall surface of the inner box, it is possible to easily foam the heat insulating material. This can prevent deformation, damage, and unsightliness of the stepped protrusion and the wall surface of the inner box.

小さく問題とならないのである。When injecting and foaming the raw materials for the foam insulation material 15, foaming jigs are installed on the outer box side and the inner box side.
The foaming jig on the inner box side has a size and shape that avoids the tubular cooler 16, so that it can be inserted into and abutted on the wall surface 13 and the stepped protrusion 14 without colliding. As mentioned above, the foaming jig on the inner box side has a size and shape that avoids the tubular cooler 16, and although this part does not come into contact with the wall surface 13, the area is extremely small and does not pose a problem.
