Description

【０００１】
【発明の属する技術分野】
本発明は冷蔵庫に関する。
【０００２】
【従来の技術】
従来の冷蔵庫を図１０〜１４を用いて説明する。
従来の冷蔵庫の扉内板１０８に小物収納容器１０９を固定する手段としては、扉内板１０８に事前に小物収納容器１０９を引掛ける孔１０８ａを開けておき、扉外板１０７ａと扉内板１０８を組合せる前に、孔１０８ａに小物収納容器１０９の鈎部形状に相当する疑似駒１１３を挿入し、疑似駒１１３が移動するのを防ぐために、移動防止駒１１４を詰めてから扉内板の裏側（ウレタン側）から軟質フィルム１１５等で疑似駒１１３と移動防止駒１１４を覆うようにかぶせて、ウレタンフォームが洩れ出ないように軟質フィルム１１５の周囲を扉内板１０８に注意深く貼り、しかる後、ウレタンフォーム発泡雇１１７に装着してウレタンフォームの発泡を行っていた。尚、小物収納容器の鈎部が入る空間部は扉の断熱材が薄くなり結露する恐れがあった。
【０００３】
しかし、この方法は疑似駒と移動防止駒のセットがめんどうなので図１２に示す如く、扉外板１０７ａにウレタン発泡を終えた冷蔵庫扉に別に成形加工しておいた扉内板１０８を、小物収納容器１０９の鈎部１０９ａが納まるスペース１１６だけ開けて被せた後、扉内板１０８の周囲をネジ１１８にて扉外板１０７ａに固定する方式とがある。
【０００４】
しかし、これらの方法においては、扉内板１０８の板厚が薄いと小物収納容器１０９に重量物が入ったりすると、扉開閉時の衝撃等により孔１０８ａの周囲が繰返し荷重によりクラックが入ったり、破れたりすることがあるため、図１２に示す如く補強板１１１をウレタンフォーム側に貼ったりしておかなければならなかったので、手間もかかったりする。しかし、補強板１１１を当てると、補強されたために荷重が内板の外周へ伝わり、扉外板１０７ａに扉内板１０８を固定しているネジ１１９の締付部１０８ｂにクラックが入ったり、破れたりする現象がみられた。
【０００５】
次に、従来の小物収納容器の取付形態について説明する。図１３に示す如く扉内板１０８に小物収納容器１０９の背面１０９ｃに設けてある鈎部１０９ａおよび１０９ｂの対向部に孔１０８ａおよび１０８ｂが形成されており、吊下げ鈎を係合穴に挿入後下方へずらすことにより小物収納容器１０９は取付けられるが、小物収納容器１０９の鈎部１０９ａおよび１０９ｂは上方に２箇所にあるだけであるため扉開閉の際に小物収納容器１０９内の収納物の重さと扉を閉めたり、開けたりの反動で鈎部を回転の支点として動くために繰返し荷重により、鈎の付根１０９ａ′および１０９ｂ′にクラックが発生することがあり、小物収納容器１０９によっては落下する恐れがあった。図１４は扉内板１０８に小物収納容器１０９が係合されている様子を示す要部断面図であり、また、図１４に示す如く、小物収納容器１０９の背面取付用の鈎部１０９ａは小物収納容器１０９の上方にあるため、扉内板１０８の孔１０８ａに小物収納容器１０９の鈎部１０９ａを挿入し、引掛けた後に引掛ける穴の一部が塞がれることなく小物収納容器１０９の上方部の扉内板１０８に鈎挿入穴１０８ａの一部が外部から見えるため見栄えが悪く、かつ収納棚近くの食品くず等が入り込む恐れがあった。
【０００６】
また、小物収納容器が透明性のある材質で成形されていると、表から鈎の付根１０９´、１０９ｂ´が透けてみえるので、見栄えが悪かった。

【発明が解決しようとする課題】
カンチレバー等の引掛け金具用のレールをつけずに見た目にスッキリしたものに仕上げるためには、扉外板に扉内板を固定した後、ウレタンフォームを発泡する方式に於いては、扉内板の小物収納容器を吊り下げるための孔部には鈎の挿入される部分だけ空洞にしておく必要があり、ウレタンフォーム発泡前に一時的に鈎部の大きさに相当する鈎疑似駒をあてがっておき、かつ、鈎疑似駒がウレタン発泡後取り出せるようにする空間を作る必要と発泡作業中に鈎疑似駒が移動しないように固定しておくために、移動防止駒を挿入して、しかる後ウレタンフォームが接着しないようにその上から軟質のフィルム等で覆っておくことが必要であり、発泡作業前後の組込み、取外しの作業に手数を要する問題があり、かつ、軟質のフィルムはウレタン液が鈎収納空間の隙間から漏洩するのを防ぐために、注意深く貼るなどの問題があった。
【０００９】
さらに、小物収納容器の鈎部が入る空間部は、扉の断熱材が薄くなり、結露する恐れがあった。
【００１０】
そこで、第一の目的は発泡前の鈎疑似駒や移動防止駒を挿入し、その上から軟質フィルムを貼って鈎挿入用の空間を作る手間がはぶけ、かつ、小物収納容器の鈎部引掛部に結露を生じない冷蔵庫を提供することである。
【００１１】
また、従来からある、扉の内板に収納容器を固定する方式のものは、事前に扉外板のみウレタンフォームを発泡したものに、別の工程で、扉内板の収納容器鈎部の係合部材を断熱材側から挿入固定し、後工程で扉内板の土手の先端部の穴から収納容器の鈎を引掛けて固定できるようにしていた。そのため、扉に発泡する際、断熱材側を成形する金型面にウレタンフォームが密着するのを防止するフィルムを貼るなどしておく必要があり、かつ、発泡済の扉体に扉内板を取付た場合、扉内板の周囲をネジなどで固定していたので、扉内板は収納容器の食品の重さと、扉開閉の振動のために、ネジの周辺に繰返し荷重がかかるため、亀裂が入りやすく、破損するなどの問題があった。そこで本発明の第二、第三の目的はウレタン密着防止のフィルムを除去し、かつ扉内板のネジ締付部に食品の荷重がかかりにくくした冷蔵庫を提供することである。
【００１２】
さらに、扉開閉により空気中の水分が穴周囲に結露して、水滴となり、穴の下部に溜まり、長期間の間には水滴が腐敗し悪臭を放つことがあるので、第四の目的は水滴が溜まらないようにする必要がある。
【００１３】
扉内板に小物収納容器を取付けるために、小物収納容器背面の鈎部を扉内板に設けた穴に係合して取付けされるが、小物収納容器の鈎部は上方にあるだけであるため、扉開閉の際に、小物収納容器内の収納物の重さと扉を開閉する際の反動で鈎部を小物収納容器の支点として動くため、繰返し荷重により、鈎の付根にクラックが発生することがあり、容器によっては落下する恐れがあると云う問題があった。そこで本発明の第４の目的は、小物収納容器の鈎部を左右の上下に２段設けることで前後の振れを防ぐことが出来ると共に満が一鈎部が一箇所破損しても他が残ることで安全な冷蔵庫を提供することである。
【００１４】
また、小物収納容器を透明性のある合成樹脂材で成形すると、吊下げ用鈎の付根がある反対側の面（表側）の面から付根が透けてみえるので、見栄えが悪くなるので、表側から目立ちにくくする必要がある。本発明の第五の目的は小物収納容器の付根が表側から目立たなくすることである。
【００１５】
また、小物収納容器背面の取付用の鈎部は小物収納ケースの上端近くにあるため、扉内板の取付穴に小物収納容器の鈎を挿入し吊した後に、吊した取付穴が蓋されることなく、外部から見えるため見栄えが悪く、食品くず等が入りやすいと云う問題があった。そこで取付穴を簡単に塞ぐことが出来る冷蔵庫を提供することにある。
【００１６】
【課題を解決するための手段】
本発明の第１、第２、および第３の目的は、扉外板と、扉内板と、前記扉外板と前記扉内板との間に充填される断熱材とを有した扉と、該扉に係止される収納容器とを備え、前記扉内板が、その両側部に前記収納容器を係合する係合孔を備えた収納箱を有し、前記扉外板と平行であって、かつ前記扉内板に接するように前記収納箱から延出した補強板を備え、該補強板はウレタンフォームと接する側の上下方向に複数のリブを有することで達成される。
【００１７】
また、収納箱が、係合孔を設けた面と対向する面に蓋を備えることで達成される。
【００１８】
扉に断熱材を発泡する前に、先ず、扉内板の両側の盛上げた土手の断熱材側に小物収納容器の鈎部を引掛ける補強用小箱を挿入し、位置決めをした後に、扉外板のフランジに扉内板をネジ止めして、その後ウレタンフォームを発泡することにより、ウレタンフォームの密着力により、扉外板と扉内板が一体となり、複数の小物収納容器から受ける荷重は一体発泡されたウレタンフォームと密着している扉内板が全面および補強用小箱で受けるので、荷重がネジ部に集中的にかかることがなく破損することを防ぐことが出来るようにする。
【００１９】
本発明の第４の目的は、収納箱が、係合孔を設けた面の下部に排水孔を備えることで達成される。なお、小物収納容器の鈎部にクラックが入るのを防止するために小物収納容器の背面を高くして、引掛け用鈎部を左右の上・下に設け、扉内板の両側の背面（断熱側）に小物収納容器の鈎部を受ける上下2段の穴を有する補強用小箱を配設することにより、扉開閉時に下段の鈎が小物収納容器が前後に振れることを防ぐことにより、鈎部に繰返し荷重がかからないので破損を防止することが出来るようにしたものである。
【００２０】
本発明の第５の目的は、収納容器が、係合孔に係合する係合部を備えると共に、透光性を有する材質により成形され、前記係合部を配置した面が、光を乱反射させる表面加工を施すことで達成される。表面加工は、細かいダイヤカット又はヘアーライン等が好ましい。
【００２１】
また、収納容器の鈎部が入る穴を塞ぐために、収納容器の背面の立上り部を高くし、上部鈎部よりさらに上方に係合穴を塞ぐ平面部を設けることにより、鈎を引掛けた後平面部が穴を塞ぐようにした。
【００２２】
【発明の実施の形態】
以下、本発明の詳細を図１〜図９に示す実施の形態で説明する。図１は本発明の一実施の形態を示す冷蔵庫の小物収納容器が取付けられている扉内板の要部断面図と小物収納容器の平面図である。図１において、１は冷蔵庫扉内板、２は小物収納容器であり、３は扉内板の断熱材側に取付けられた補強用小箱であり、図５に示す補強用小箱３の表面の凸部３ｃは図４に示す扉内板１に補強用小箱を収容することで、扉の断熱材が薄くなるのを防止するために設けた土手部先端に設けた孔１ｂに嵌入することにより位置が決まり、かつ補強用小箱３の孔３ａには扉内板の浅い土手の内側の傾斜が作るガイド部１ａに、小物収納容器２の後側の形状が、丁度扉内板のガイド部１ａの形状に一致するように形成されているので、小物収納容器２を扉内板の形状即ちガイド１ａに沿って押し込むと独りでに小物収納容器の背面に形成されている鈎部２ｂが、補強用小箱の孔３ａに入り下に下げることにより小物収納容器２は扉内板に取付けられた補強用小箱３と係合して取付くのである。
【００２３】
図２は本発明の一実施の形態を示す扉内板１と扉外板４ａとの間にウレタン発泡した時の扉４の要部横断面図であり、扉４に断熱材５を発泡する前に、先ず扉内板１の両側の浅い土手の断熱材側に図３に示す如く、小物収納容器２の鈎部２ｂを引掛ける補強用小箱３を挿入し、位置を決めた後に扉外板４ａのフランジ部４ｂに扉内板１をネジ６にて止め、その後ウレタンフォーム５を発泡することにより、ウレタンフォーム５の密着力により、扉外板４ａと扉内板１が一体となるので、複数の小物収納容器２（図示せず）が取付けられた時の荷重は、一体発泡されたウレタンフォーム５と密着している扉内板１および図６に示す補強板３ｅが同時成形されている補強用小箱３とが全面で受けるので、小物収納容器２の荷重が狭い部分に集中的にかかることがなくなり、小物収納容器２の繰返し荷重に耐え、破損することを防止できる。
【００２４】
図３は本発明の一実施の形態を示す小物収納容器２の鈎部取付の際、補強用として取付けられる補強用小箱取付部の要部縦断面図である。即ち、従来採用していた鈎部疑似駒や移動防止駒を挿入する代りに、小物収納容器２の背面に設けてある鈎２ｂを引掛ける部分として、前面に穴３ａをあけた補強用小箱３を扉内板１のウレタンフォーム側から取付け、ウレタン発泡後に使う鈎部２ｂを収納する空間を確保しておく構造である。
【００２５】
尚、補強用小箱３の取付は図４に示す、扉内板１の土手部に相当するガイド部１ａの先端部に設けた孔１ｂに図５に示す補強用小箱３の嵌入部３ｃを嵌めるようにして補強用小箱３をガイド部１ａ（図１参照）の溝へ押し込む。この時、補強用小箱３の横断面形状は扉内板１のガイド部１ａの断面形状にあらかじめ合せてあるので、合致する。合致後は戻らないように粘着テープ７等にて固定しておく。補強用小箱３のウレタンフォーム断熱材側の形状は図６に示す如く、補強用小箱から延出した補強板３ｅに複数のリブ３ｆが成形されており、ウレタン発泡された時に、補強用小箱３がウレタン５と密着し補強用小箱に外力が加わってウレタンフォームから剥れたり、荷重により扉内板１が破れたりしない工夫をしてある。尚、図４は、扉内板に小物収納容器の補強用小箱を取付けるための孔があいている様子を示す斜視図である。
【００２６】
補強用小箱３の前面に小物収納容器２の鈎部２ｂを引掛ける支持部３ｂを作るために補強用小箱３の背面３の背面側にヒンジ機構を有す蓋３ｇを補強用小箱３と一体で成形加工しておき、ウレタン発泡前に閉めておくと鈎部２ｂを収納する空間が容易にできて大変便利である。したがって、従来のように疑似駒や移動防止駒が不要となり、又ウレタン洩れ防止のシートも不要であるため、作業効率の大巾アップが計れる。
【００２７】
尚、図６は補強用小箱を裏側（断熱材側）から見た斜視図であり、補強用小箱３にリブ３ｆを有する補強板３ｅと蓋３ｇが一体に成形された様子を示す。
【００２８】
図５は補強用小箱の正面側から見た斜視図であり補強用小箱の最下部には排水孔３ｄが設けてあるので、扉開閉により冷えている補強用小箱の内面に空気中の水分が結露したとしても排水されるので、長いこと溜まっていることがないので、水が腐敗して臭いを放つことを防止できる。
【００２９】
図７は冷蔵庫の扉内板１の内部に取付けられる小物収納容器２の正面斜視図と裏側の斜視図８および小物収納容器の鈎部の表面処理を示す斜視図９である。図８に示す如く、小物収納容器２の背面部２ｃを高くして射出成形加工にて収納部２ｄと同時成形で鈎部２ｂを左右・上下に４箇所設けてある。したがって上部および下部の左右４個の鈎部が分担して重量をささえ、下部の左右２個が、扉開閉時の衝撃で小物収納容器２が前後に振れるのをおさえているので、扉開閉時の衝撃による繰返し荷重で、鈎２ｂの付根２ｂ´が被労してクラックが入ったり、破損したりするのを防ぐことが出来る。尚、この場合上下の鈎部２ｂは離れて施けるほうが上部の２個が支点となるので、回転モーメントが小さくなり有利である。又、図７に示す如く小物収納容器２自体を透明性のある材質で成形すると正面から見た時鈎の付根２ｂ′が正面からみえて見苦しく気になるので、図９に示す如く鈎の付根がある部分２ｃの表面に細かいダイヤカット２ｅとかヘアーラインを施すことにより光を乱反射させて、鈎の付根が目立ちにくくした。
【００３０】
図３は本発明の一実施の形態を示す小物収納容器２と扉内板１と補強用小箱３の関係を示す要部断面図であり、図３に示す如く、小物収納容器２の鈎部２ｂは扉内板１の断熱材側に設けられた小物収納容器２の鈎部２ｂを引掛け収納する補強用小箱３の孔３ａを通過後、鈎２ｂを支持する支持部３ｂに係止されている。しかし、この時、補強用小箱３の孔３ａは鈎部の頭部２ｂ′が通過できるように、頭部２ｂ′より大き目にあけておくので、もし、頭部２ｂ′が小物収納容器２の背面板２ｃの上端に設けた場合は穴３ａの一部が外部から見えたり、食品くず等が入ったりするので孔３ａを被いかくす目的で背面板２ｃを上方に延ばして穴３ａを塞ぐ部分２ｆを設けた。
【００３１】
【発明の効果】
以上詳細に説明したように、本発明によれば、補強用小箱が組込まれた扉内板と扉外板をウレタン発泡で一体に加工したので、扉内板に小物収納容器の荷重がかかっても補強用小箱の補強板と扉内板全体で受けるので、荷重が分散し扉内板の固定用ネジ部にかかる力が弱くなり、ネジ部の破損の少ない冷蔵庫を提供することが出来る。
【００３２】
扉内板の断熱材側に小物収納容器の鈎部収納用の蓋付補強用小箱を設置したので、ウレタン発泡前の疑似駒や移動防止駒が不要となり、又ウレタン洩れ防止シートなども不要となり、生産効率の高い冷蔵庫を提供することができる。
【００３３】
複数のリブ付補強板を補強用小箱と一体で成形したので、ウレタンフォームと密着し、強度の高い取付構造となり、小物収納容器の荷重で内板が破損しにくくなった。
【００３４】
扉開閉により補強用小箱の穴に水滴が付着したとしても最下部に設けた排水孔より水が庫内側に流れるので溜まることがなく腐敗して臭いを放つことがない。
【００３５】
小物収納容器の鈎部を上下・左右に設けたので、扉開閉時の衝撃による前後のゆれがなくなり、鈎部の繰返し荷重がかからなくなったので鈎部のクラックや破損が発生しにくい冷蔵庫を提供することができる。
【００３６】
透明性のある材質で小物収納容器を作成し、背面に取付用の鈎部を設けた時に、鈎部の表面にダイヤカットやヘアーラインを施したので鈎部の付根が乱反射で見えにくくなり、見栄えの良い冷蔵庫を提供することができる。
【００３７】
扉内板に設置された補強用小箱に設けられた小物収納容器の鈎部挿入穴を小物収納容器の背面板が覆うようにしたので、小物収納容器を組付後、外から穴が見えないので、見栄のよい冷蔵庫を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a refrigerator.
[0002]
[Prior art]
A conventional refrigerator will be described with reference to FIGS.
As a means for fixing the accessory storage container 109 to the door inner plate 108 of the conventional refrigerator, a hole 108 a for hooking the accessory storage container 109 is opened in the door inner plate 108 in advance, and the door outer plate 107 a and the door inner plate 108 are opened. In order to prevent the pseudo piece 113 from moving, the pseudo piece 113 corresponding to the shape of the collar of the small article storage container 109 is inserted into the hole 108a and the movement preventing piece 114 is packed, Cover the dummy piece 113 and the movement prevention piece 114 with the soft film 115 or the like from the back side (urethane side) and carefully attach the periphery of the soft film 115 to the door inner plate 108 so that the urethane foam does not leak out. It was mounted on urethane foam foaming staff 117 and foamed urethane foam. In addition, in the space part in which the collar part of an accessory storage container enters, there was a possibility that the heat insulating material of a door might become thin and condensation might occur.
[0003]
However, since this method is troublesome to set the dummy piece and the movement preventing piece, as shown in FIG. 12, the door inner plate 108, which has been separately molded into the refrigerator door after urethane foaming on the door outer plate 107a, is replaced with a small container. There is a method in which a space 116 in which 109 collars 109 a are accommodated is opened and covered, and then the periphery of the door inner plate 108 is fixed to the door outer plate 107 a with screws 118.
[0004]
However, in these methods, if the door inner plate 108 is thin and a heavy article enters the small article storage container 109, the surroundings of the hole 108a may crack due to repeated loads due to an impact at the time of opening and closing the door, Since it may be torn, the reinforcing plate 111 had to be stuck on the urethane foam side as shown in FIG. However, if the reinforcing plate 111 is applied, the load is transmitted to the outer periphery of the inner plate due to reinforcement, and the tightening portion 108b of the screw 119 fixing the door inner plate 108 to the door outer plate 107a is cracked or torn. There was a phenomenon.
[0005]
Next, the attachment form of the conventional accessory storage container is demonstrated. As shown in FIG. 13, holes 108a and 108b are formed in the door inner plate 108 at opposite portions of the flanges 109a and 109b provided on the back surface 109c of the small article storage container 109, and the suspended rods are inserted into the engagement holes. The accessory storage container 109 is attached by being shifted downward, but since the flanges 109a and 109b of the accessory storage container 109 are only at two positions on the upper side, the weight of the storage object in the accessory storage container 109 is reduced when the door is opened and closed. Since the collar moves as a fulcrum of rotation due to the reaction of closing and opening the door, cracks may occur in the roots 109a 'and 109b' of the collar due to repeated loads, and depending on the small article storage container 109, it may fall There was a fear. FIG. 14 is a cross-sectional view of a main part showing a state in which the small article storage container 109 is engaged with the door inner plate 108. As shown in FIG. Since it is above the storage container 109, the hook 109 a of the small storage container 109 is inserted into the hole 108 a of the door inner plate 108, and the hook of the small storage container 109 is not clogged after being hooked. Since a part of the eaves insertion hole 108a can be seen from the outside in the upper door inner plate 108, it looks bad and there is a risk that food scraps near the storage shelf may enter.
[0006]
In addition, when the accessory storage container is formed of a transparent material, the bases 109 'and 109b' of the heel can be seen through from the table, so that the appearance is poor.
[0007]

[0008]
[Problems to be solved by the invention]
In order to create a clean appearance without attaching a rail for a hook metal fitting such as a cantilever, after fixing the door inner plate to the door outer plate and then foaming urethane foam, the door inner plate It is necessary to leave only the part in which the heel is inserted in the hole for hanging the small container, and temporarily attach a heel pseudo piece corresponding to the size of the heel before foaming the urethane foam. In addition, it is necessary to create a space that can be removed after the urethane foam is foamed, and in order to fix it so that it does not move during the foaming operation, a movement prevention piece is inserted, and then urethane It is necessary to cover the foam with a soft film to prevent the foam from adhering to it, and there is a problem that it takes a lot of work to install and remove before and after the foaming work. Liquid is to prevent the leaking from the gap hook housing space, there are problems such as sticking carefully.
[0009]
Furthermore, in the space part in which the collar part of the small article storage container enters, there is a possibility that the heat insulating material of the door becomes thin and dew condensation occurs.
[0010]
Therefore, the first purpose is to insert the dummy pad and anti-moving piece before foaming and stick the soft film on it to make the space for inserting the bag, and the hook part of the small container It is to provide a refrigerator that does not cause condensation.
[0011]
In addition, the conventional method of fixing the storage container to the inner plate of the door is a process in which urethane foam is foamed only on the door outer plate in advance. The joint member was inserted and fixed from the heat insulating material side, and was able to be fixed by hooking the hook of the storage container from the hole at the tip of the bank of the inner plate of the door in a later process. Therefore, when foaming to the door, it is necessary to stick a film to prevent the urethane foam from sticking to the mold surface that molds the heat insulating material side, and the door inner plate is attached to the foamed door body. When installed, the periphery of the door inner plate was fixed with screws, etc., so the door inner plate was repeatedly loaded around the screws due to the weight of food in the storage container and the vibration of the door opening and closing. There was a problem that it was easy to enter and was damaged. Accordingly, a second and third object of the present invention is to provide a refrigerator in which a film for preventing urethane adhesion is removed and a load of food is hardly applied to a screw tightening portion of a door inner plate.
[0012]
In addition, when the door is opened and closed, moisture in the air condenses around the hole, forming water droplets that accumulate in the lower part of the hole, and the water droplets may rot and give off a bad odor over a long period of time. It is necessary not to accumulate.
[0013]
In order to attach the accessory storage container to the door inner plate, it is attached by engaging the flange on the back of the accessory storage container with the hole provided in the door inner plate, but the accessory storage container is only on the upper side. Therefore, when the door is opened and closed, the collar moves as a fulcrum of the small container due to the weight of the small container and the reaction when the door is opened and closed.

【The invention's effect】
As described above in detail, according to the present invention, since the door inner plate and the door outer plate in which the reinforcing small box is incorporated are integrally processed with urethane foam, the load of the small container is applied to the door inner plate. However, since it is received by the reinforcing plate of the reinforcing small box and the entire inner plate of the door, the load is dispersed and the force applied to the fixing screw portion of the door inner plate becomes weak, and a refrigerator with less damage to the screw portion can be provided. .
[0032]
Since a small box with a lid for storing the buttock of a small container is installed on the heat insulating material side of the door inner plate, there is no need for a dummy piece or movement prevention piece before urethane foaming, and no urethane leak prevention sheet, etc. Thus, a refrigerator with high production efficiency can be provided.
[0033]
Since a plurality of reinforcing plates with ribs are molded integrally with the reinforcing small box, it is in close contact with the urethane foam and has a high strength mounting structure, and the inner plate is less likely to be damaged by the load of the small container.
[0034]
Even if water droplets adhere to the hole of the reinforcing small box by opening and closing the door, water flows from the drain hole provided in the lowermost part to the inside of the warehouse, so it does not accumulate and does not rot and give off odor.
[0035]
As the small container storage box is provided on the top, bottom, left and right, the front and back are not shaken by the impact when the door is opened and closed, and the repeated load on the hook is no longer applied. Can be provided.
[0036]
When a small container is made of a transparent material and a mounting collar is provided on the back, diamond cuts and hairlines are applied to the surface of the collar, making the base of the collar difficult to see due to irregular reflections A good refrigerator can be provided.
[0037]
Since the back plate of the small storage container covers the buttock insertion hole of the small storage container provided in the reinforcing small box installed on the inner plate of the door, the hole can be seen from the outside after the small storage container is assembled. Since it does not exist, it can provide a nice-looking refrigerator.
