を装設する箱体の構造に関するものである。[Detailed description of the invention] The present invention relates to a refrigerator box body, and in particular, the structure of the box body is provided with a partition wall member that partitions the inside of the box in the front and back direction between two inner boxes installed in the outer box. It is related to.

ないものであった。In this way, an inner box that constitutes a freezer compartment and a refrigerator compartment is installed inside the outer box, and a partition wall member that divides the inside of the box in the front and back direction is installed between the nine inner boxes. In the case where a stock solution of hard urethane foam is injected into the space formed between the foam and the foam solidifies to form a heat insulating wall, the partition wall member significantly obstructs the flow of the stock solution during foaming, resulting in good foaming. It was impossible.

本考案は上記従来型の欠陥を除去するもので。The present invention eliminates the above-mentioned deficiencies of the conventional type.

以下９本考案の一実施例を図面によって説明すると、１
は冷蔵庫の箱体で、外箱２と、この外箱２内に装設され
る冷凍室を構成する内箱３及び冷蔵室を構成する内箱４
と、この両内相３，４間に箱内を両側を除いて前後方向

両内相３，４間に充填される断熱壁６とにより構成され
ており。One embodiment of the nine inventions will be explained below with reference to the drawings.
is a box body of a refrigerator, which includes an outer box 2, an inner box 3 installed in the outer box 2 that constitutes a freezer compartment, and an inner box 4 that constitutes a refrigerator compartment.
A partition wall member 5 is installed between the two inner phases 3 and 4 so as to partition the inside of the box in the front and back direction except for both sides, and a partition wall member 5 is installed between the outer box 2 and both inner phases 3 and 4. It is composed of a heat insulating wall 6.

断熱壁６は外箱２の底面に形成した注入ロアから硬質ウ
レタンフオームの原液を外箱２の背面に沿って注入し発
泡細化させることによって形成する。The heat insulating wall 6 is formed by injecting an undiluted solution of hard urethane foam along the back surface of the outer box 2 from an injection lower formed on the bottom surface of the outer box 2, and foaming and thinning the foam.

８は前記仕切壁部材５の外箱２の背面との当接面の略中
夫に形成した発泡時の原液を過させるための凹部である
。Reference numeral 8 designates a recessed portion formed approximately at the center of the abutting surface of the partition wall member 5 with the back surface of the outer box 2, for allowing the undiluted solution during foaming to pass through.

従って９箱体１の形成に当っては、仕切壁部材５を内箱

の背面に沿って外箱２の天井面に向って急速に流れるが
、その流れは前記仕切壁部材５によって阻害されること
はなく凹部８を通して天井面に向うことになるため良好
な発泡を行うことができる。Therefore, when forming the 9-box body 1, the partition wall member 5 is attached to either one of the inner boxes 3, 4, the inner boxes 3, 4 are attached to the outer box 2, and then the box body 1 is attached to the outer box 2. When set in a jig (not shown) with the opening facing upward and injecting the stock solution of hard urethane foam from the injection lower, the stock solution will be poured into the outer box 2.
The foam rapidly flows toward the ceiling surface of the outer box 2 along the back surface of the outer box 2, but the flow is not obstructed by the partition wall member 5 and flows toward the ceiling surface through the recess 8, thereby achieving good foaming. be able to.

なお９本考案においては前記仕切壁部材５に形成する凹
部を外箱との当接面の略中夫に１ケ所だけ形成するもの
について説明したが、これに限定されるものではなく９
例えば金山にわたって複数ケ所形成するようにしてもよ
い。9 In the present invention, the recess formed in the partition wall member 5 is formed only at one location approximately at the center of the contact surface with the outer box, but the present invention is not limited to this.
For example, they may be formed at multiple locations across the gold mine.

以上説明したように９本考案によると二つの内箱間に箱
内を前後方向に区画する仕切壁部材の外箱の背面との当
接面に発進時外箱の背面に沿って流れる原液を通過させ

が仕切壁部材によってその流通を阻害されることはなく
、良好な発泡を行うことができるものである。As explained above, according to the present invention, the undiluted liquid that flows along the back surface of the outer box at the time of starting is applied to the contact surface of the partition wall member that partitions the inside of the box in the front and back direction between the two inner boxes with the back surface of the outer box. Since a concave portion is formed for passage, the flow of the stock solution is not obstructed by the partition wall member as in the conventional type, and good foaming can be performed.
