Japanese Utility Model Publication No. 02-024283

従来の冷蔵庫の引出し扉装置は以上のように構成されているので、固定ローラー８へ引出し扉の荷重が常に掛かり、また引出し扉の開閉により固定ローラー取付部が摩耗するため、下側中仕切壁９は強固で対摩耗性の強い材料を使用する必要があり、コスト等の関係上ＰＰ（ポリプロピレン）等の材料で対応しなければならなかった。
このため、客先等で固定ローラー取付部が摩耗もしくは破損した場合には、製品本体を交換するしか手段が無く、サービス性は皆無に等しかった。 Since the drawer door device of the conventional refrigerator is configured as described above, the load of the drawer door is always applied to the fixed roller 8, and the fixed roller mounting portion is worn by opening and closing the drawer door, so the lower partition wall No. 9 needs to use a strong and highly wear-resistant material, and has to cope with a material such as PP (polypropylene) due to cost and the like.
For this reason, when the fixed roller mounting portion is worn or damaged at the customer's site or the like, there is only a means for replacing the product body, and the serviceability is not at all.

さらに、ローラー取付部は凹形状であるため、凹部へ水が溜まりやすく不衛生であり、もし仮にローラー取付部が冷凍室であった場合、水が氷結することにより固定ローラー８が全く摺動せず、引出し扉の開閉が非常に困難になると云う問題があった。   Furthermore, since the roller mounting portion has a concave shape, water tends to accumulate in the recess and is unsanitary. If the roller mounting portion is a freezer compartment, the fixed roller 8 slides completely due to water freezing. Therefore, there is a problem that opening and closing of the drawer door becomes very difficult.

また、近年、野菜室、切替室等、冷蔵庫の中段部へ引出し式の大きなケースを備えた製品が増えており、引出し扉の支持部（ローラー取付部、フレーム等）へは多大な負担が掛かっている。さらに、引出し扉を引出した状態で、引出し扉へ子供がぶらさがる等、過大な荷重が掛かる可能性があり、引出し扉の支持部を補強する必要があった。特に固定ローラー取付部を支持している下側中仕切壁９は、ＰＰ等の合成樹脂である為、耐衝撃性に劣り、固定ローラー取付部周辺が変形、及び破損することがあった。   In recent years, products with large drawer-type cases have been increasing in the middle part of refrigerators, such as vegetable rooms and switching rooms, and a large burden is placed on the support parts (roller mounting parts, frames, etc.) of drawer doors. ing. Furthermore, there is a possibility that an excessive load is applied, such as a child hanging on the drawer door in a state where the drawer door is pulled out, and it is necessary to reinforce the support portion of the drawer door. In particular, since the lower middle partition wall 9 supporting the fixed roller mounting portion is made of synthetic resin such as PP, the impact resistance is inferior, and the periphery of the fixed roller mounting portion may be deformed and damaged.

この発明は、かかる問題点を解消するためになされたもので、ローラー取付部のサービス性を改善し、ローラー取付部を衛生的に保つことができ、引出し扉の開閉を妨げることを防止できる冷蔵庫を提供することを目的とする。   The present invention has been made to solve such problems, and can improve the serviceability of the roller mounting portion, keep the roller mounting portion sanitary, and prevent the opening and closing of the drawer door from being hindered. The purpose is to provide.

この発明に係る冷蔵庫は、冷蔵庫本体と、この本体の貯蔵室を区画し、前面に中仕切鋼板を有する中仕切壁と、貯蔵室に設けられ、食品収納ケースを載置するフレームが取り付けられた引き出し扉と、本体に設けられ、フレームを下方より支持する固定ローラーと、中仕切壁に設けられ、固定ローラーを収納し、中仕切壁とは別部品で形成された固定ローラー収納部と、この固定ローラー収納部の前部と横部とに設けられ、引き出し扉の引出し時の左右のブレを抑制するＬ字形のリブとを備えたことを特徴とする。 The refrigerator according to the present invention is provided with a refrigerator main body, a partition wall for partitioning the storage chamber of the main body, having a partitioning steel plate on the front surface, a frame provided in the storage chamber and on which a food storage case is placed. A drawer door, a fixed roller provided on the main body and supporting the frame from below, a fixed roller storage part formed on a partition wall, which stores the fixed roller and is formed as a separate part from the partition wall , It is provided in the front part and the horizontal part of a fixed roller storage part, and was equipped with the L-shaped rib which suppresses the blurring of right and left at the time of drawer | drawing-out of a drawer door .

この発明に係る冷蔵庫は、上記構成により、引出し扉を引出した状態において、引出し扉へ過大な荷重が掛かった場合でも、中仕切部の変形、及び破損を防止できる。また、ローラー収納ボックスの前部と横部に設けたＬ字形のリブで、引出し扉を引出した時の左右のブレをフレームと当接させることにより抑制できる。 The refrigerator which concerns on this invention can prevent a deformation | transformation and damage of a partition part by the said structure, even when an excessive load is applied to the drawer door in the state which pulled out the drawer door. In addition, L-shaped ribs provided on the front and side portions of the roller storage box can be suppressed by bringing the left and right blurs when the drawer door is pulled out into contact with the frame.
