Description

【０００１】
【発明の属する技術分野】
本発明は、製氷機，冷却貯蔵庫，貯氷庫又は保温庫等の貯蔵庫の取出口を開閉する断熱ドア構造の改良に関するものである。
【０００２】
【従来の技術】
従来、製氷機の断熱ドア構造は、図５に示す如く、製氷機本体１の手前側Ａに開口した氷取出口１ａをドア２で開閉するものであり、製氷機本体１にドア２がヒンジ３を介して取付けられている。ドア２は、ドア裏面側に突設したストッパー片４を、製氷機本体１に設けた開口部１ｃからストッパー格納室１ｂへ挿入し、二点鎖線で示すように開いたときのストッパー片４の引掛け部４ａを開口部１ｃの縁部１ｄに引っ掛けるようにしてある。ドア２は、通常は、製氷機本体１の氷取出口１ａを閉じるように直立した状態に位置しているが、製氷機本体１から氷を取り出すときには、ヒンジ３を中心として手前側に傾倒し、ストッパー片４の引掛け部４ａを開口縁部１ｄに引っ掛けることで、開放状態を保持する。
【０００３】
上記ドア２は、図４に示す如く、断熱組６と、ドア断熱組６の裏面を覆う合成樹脂製裏蓋７と、把手８とを備えている。ドア断熱組６は、金属製ケーシング５の表板５ａ、周縁片５ｂ及び裏接合片５ｃで、内側に充填してある発泡ウレタン製断熱層６ａを囲むように構成してある。ドア２は、四辺の裏接合片５ｃに裏蓋７をビス又はリベット等で接合すると共に、上方の周縁片５ｂに把手８をビス又はリベット等で接合してある。ドア断熱組６は、金属製ケーシング５の周縁片５ｂに、金属製ストッパ−片４をスポット溶接で接合してある。合成樹脂製裏蓋７は、剛性を高めるために、凹凸部７ａを形成してある。ドア２は、断熱組６と裏蓋７との間に、パッキン９を配置することもある。このドア構造は、製氷機以外に、断熱壁で庫内を囲むように形成した冷却貯蔵庫，貯氷庫又は保温庫等の貯蔵庫の取出口を開閉する断熱ドアに適用することもある。
【０００４】
【発明が解決しようとする課題】
従来の貯蔵庫の断熱ドア構造には、次のような問題があった。
（１）断熱組６に裏蓋７及びストッパ−片４を別々に接合してあるため、部品点数及び接合のための作業工数が多くなる。
（２）貯蔵庫本体（製氷機本体）１にストッパー格納室１ｂを設けるため、貯蔵庫本体（製氷機本体）１の部品点数及び製造工数が多くなる。また、手前側に開口部１ｃが露出するため、見栄えが悪いと共に、水等がストッパー格納室１ｂへ浸入して不衛生になることがある。
（３）ドア断熱組６に裏蓋７及び把手８を別々に接合してあるため、部品点数及び接合のための作業工数が多くなる。
【０００５】
更に、次のような問題もある。
（４）ケーシング５の周縁片５ｂとストッパ−片４とのスポット溶接の跡が、周縁片５ｂの外側に露出するため、見栄えが悪い。
（５）合成樹脂製裏蓋７をビス又はリベット等で接合するとき、裏蓋７に割れ等の不良が生じないように注意を払う必要があるため、製造上の管理に手間を要する。
（６）発泡ウレタン製断熱層６ａに合成樹脂製裏蓋７が接触するため、裏蓋７の素材として、発泡ウレタン製断熱層６ａに耐える耐アタック性のものを選択する必要があり、面倒である。
（７）合成樹脂製裏蓋７に付着した汚れ等を除去するときに、その凹凸部７ａが邪魔となるため、清掃に多くの手間を要する。
【０００６】
本発明は、前記（１）乃至（３）の問題を解決するための貯蔵庫の断熱ドア構造の提供を目的とするものである。
【０００７】
【課題を解決するための手段】
