Description

本実施形態は、冷蔵庫の組み立てシステム及び冷蔵庫に関する。   The present embodiment relates to a refrigerator assembly system and a refrigerator.

冷蔵庫では、内箱と外箱との間に断熱材を配設ことで、冷蔵庫の筐体を構成する断熱箱体が形成されている。   In the refrigerator, a heat insulating material constituting the casing of the refrigerator is formed by disposing a heat insulating material between the inner box and the outer box.

しかしながら、上記構成の冷蔵庫では、内箱が断熱箱体の容積に合わせた大きさの立体的な形状であり、断熱箱体の容積が異なる毎に異なる大きさの内箱が必要となるため、容積毎にサイズの異なる内箱を中間部材として用意しなければならず、広いストックスペースや中間在庫を持つ必要があり、複数品種生産に対応させることが困難になる問題がある。   However, in the refrigerator having the above configuration, the inner box has a three-dimensional shape that matches the volume of the heat insulating box, and each time the inner box has a different volume, different inner boxes are required. Inner boxes of different sizes for each volume must be prepared as intermediate members, and it is necessary to have a wide stock space and intermediate stock, which makes it difficult to handle multiple types of production.

また、内箱は、真空成形などによる樹脂成型品であることから、成形型から脱型するための抜きテーパが内箱に存在する。上記構成の冷蔵庫では、内箱と外箱との間の全部あるいは一部に発泡断熱材を充填する場合、内箱の内面を面接触状態で支持する治具が必要となるが、内箱にテーパが存在するとサイズの異なる内箱で治具を共通化することができず、各容積毎に治具が必要となる。そのため、容積の異なる品種が増えるにつれて、治具に関する設備費や治具をストックするスペースも増大し、複数品種生産に対応させることが困難になる問題がある。   Further, since the inner box is a resin molded product by vacuum molding or the like, a punching taper for removing from the mold is present in the inner box. In the refrigerator having the above configuration, when all or part of the space between the inner box and the outer box is filled with the foam insulation, a jig for supporting the inner surface of the inner box in a surface contact state is required. If there is a taper, a jig cannot be shared by inner boxes of different sizes, and a jig is required for each volume. Therefore, as the number of products having different volumes increases, the equipment cost related to the jig and the space for stocking the jig also increase, which makes it difficult to cope with the production of a plurality of products.
