Description

【０００１】
【発明の属する技術分野】
この発明は貯氷庫に関し、更に詳細には、貯氷庫に配設された氷取出用の内外の扉を開放した際に、庫内に貯留されている氷塊が内扉の隙間からこぼれ出ないようにした貯氷庫に関するものである。
【０００２】
【従来の技術】
製氷部で連続的に製造した氷塊を貯氷庫に貯留する自動製氷機が、喫茶店やレストラン等の施設その他の厨房において好適に使用されている。本発明は、この自動製氷機に採用される貯氷庫に関するものであるので、理解に資するため先ず貯氷庫の概略につき、図１０を参照して説明する。
【０００３】
図に示す貯氷庫１０は、所要形状に成型された外箱２４、内箱２６および両箱２４,２６間に充填された断熱材２７から構成された筐体２８を本体とし、該筐体２８の内部に、所要量の氷塊４０を貯留する貯氷室を画成すると共に、筐体２８の前面部には氷取出用の氷取出口３０が開設してある。また、氷取出口３０より下方の筐体２８前面にヒンジ３２が配設されると共に、該ヒンジ３２には外扉１８がその下端部を回動自在に枢支されている。そして、外扉１８の上端部を筐体２８の前面に対して近接・離間するようヒンジ３２を介して回動することで、前記氷取出口３０を開閉するよう構成される。なお、図示例の筐体２８は、該筐体２８の後方や側方に設けた図示しない製氷部から放出される氷塊を受容するために、後壁や側壁の上部に開口が設けられるものであるが、筐体２８の上方に配置した製氷部から放出される氷塊を受容するために天部を全面的に開放したものであってもよい。
【０００４】
前記筐体２８の内部には、前記外扉１８の回動に追従して回動して氷取出口３０を開閉する内扉１２が配設されている。この内扉１２は、その断面が略コ字状に成形された器状の部材であって、貯氷室(庫内)に貯留されている氷塊４０を筐体２８の前面側に案内する氷案内板１２ａと、該氷案内板１２ａの幅方向両端部においてこれと略直交するよう夫々立設された側板１２ｂ,１２ｂとから基本的に構成される。前記筐体２８の内箱２６における幅方向の両内側壁には、前記氷取出口３０の下部内周縁から庫内に所定間隔離間した位置に、対向するよう水平に突出する一対の支持部３６,３６が配設されている。そして、両支持部３６,３６を、前記側板１２ｂ,１２ｂの下部に穿設した取付孔(回動支持部)１２ｃ,１２ｃに回動自在に係合することにより、内扉１２は筐体２８に対して回動自在に枢支される。また内扉１２における氷案内板１２ａの上端は、前記外扉１８の裏面に配設された断面Ｌ字状のホルダ３８に係脱自在に係合するように構成されている。
【０００５】
前記外扉１８が氷取出口３０を閉成している状態では、図１０(ａ)に示す如く、前記内扉１２は、前記ホルダ３８に上端が係合した状態で略垂直位置に支持されている。そして、この状態から外扉１８の上端部を筐体２８の前方に向けて傾倒するよう該外扉１８を回動することにより、内扉１２はその上端がホルダ３８に係合した状態で外扉１８に追従して一体的に回動する。このとき内扉１２は、外扉１８とは異なった回動支点を中心に回動するため、外扉１８のホルダ３８と内扉１２の上端とは、その回動につれて相互に離間移動し、外扉１８が所定位置まで回動したときにホルダ３８が内扉１２の上端から離脱する。更に外扉１８を回動終点まで回動する際には、内扉１２はその上端を外扉１８の裏面に沿って摺動させつつ外扉１８と一体的に筐体２８の前方に傾倒し、図１０(ｂ)に示すように前記氷取出口３０を開放する。
【０００６】
前記外扉１８を回動終点まで回動させた際には、図１０(ｂ)に示すように、前記内扉１２は、氷案内板１２ａが外扉１８と略平行となる位置で停止すると共に、一対の側板１２ｂ,１２ｂが庫内から庫外に亘って延在する状態で臨む。これにより貯氷室内に貯留された氷塊４０は、前記氷案内板１２ａで筐体２８の前面側に案内されると共に、側板１２ｂ,１２ｂによって氷取出口３０から外部側方にこぼれ落ちるのは阻止される。
【０００７】
【発明が解決しようとする課題】
前述した貯氷庫１０では、前記内扉１２を開放した際に氷案内板１２ａと氷取出口３０の下部内周縁との間に、氷塊４０が外部にこぼれ落ちる隙間が画成されるのを防ぐために、該内扉１２を枢支する支持部３６,３６が、内箱２６における氷取出口３０に極めて近接する位置に設定されている。このため支持部３６,３６を内箱２６と一体成形した場合には、該支持部３６,３６と内箱２６との接続部分等に良好な仕上がりが期待できないばかりか、内箱２６に対する内扉１２の取付けが困難となる欠点があった。そのため従来は、内箱２６を複数の板材を相互に連結して構成すると共に、前記支持部３６,３６についても後付けにより配設していた。例えば支持部３６,３６を設けるべき箇所に、円筒状の突起部を水平方向に対向して接着したり、あるいは内箱２６に穴を設け、該穴に支持部３６を取付けるためのシャフトやネジ等の止着部材を配設していた。しかるにこの場合には、必然的に部品点数が多くなってコストが嵩む欠点を招いていた。また清掃等のために内扉１２を内箱２６から取外す際には、これらの止着部材等を内箱２６から取外さなければならず、多くの時間と手間が掛かる等の難点も指摘される。更には、内箱２６が一体成形でないため、各板材の継目やコーナー部の洗浄が困難であった。
【０００８】
なお、前記内扉１２の前面下部に膨出部を設け、内扉１２の開閉状態の如何に拘らず、常に氷取出口３０の下部内周端に膨出部を近接させるよう構成することで、内扉１２と内箱２６との枢支位置を氷取出口３０の下部内周端から離間させる提案がある。しかしこの場合は、膨出部が氷取出口３０の下部内周端に常に近接しているため、該部分の清掃が極めて困難であり、清掃に際しては内箱２６から内扉１２を取外す煩雑な作業が必要となっていた。
【０００９】
【発明の目的】
本発明は、前述した従来の技術に内在している前記課題に鑑み、これを好適に解決するべく提案されたものであって、氷取出口を開閉する内扉を開放した際に庫内から氷塊がこぼれ出るのを防止すると共に、清掃を容易に行ない得る貯氷庫を提供することを目的とする。
【００１０】
【課題を解決するための手段】
前記課題を克服し、所期の目的を好適に達成するため本発明に係る貯氷庫は、
内部に氷塊を貯留する筐体と、該筐体に下端部が回動可能に配設され、その上端部を筐体に対して近接・離間するよう回動することで該筐体に開設した氷取出口を開閉する外扉と、この外扉の裏面と対向する氷案内板の幅方向両側に筐体の両内側壁と対向する一対の側板を備え、両側板の下部に設けた回動支持部を介して両内側壁間に回動自在に枢支され、前記外扉の回動に追従して回動して氷取出口を開閉する内扉とからなる貯氷庫において、
前記内扉における氷案内板の前面下部に、幅方向に長い長方形状の板部材を短手方向の略中央部で鈍角の山型に屈曲させて前面側に突出すると共に、短手方向に延在するスリットが幅方向に離間して複数形成された規制体が設けられ、
前記内扉は、該内扉を閉成した際には前記規制体が前記氷取出口の下部内周縁に対し庫内への手指等の挿入を許容する長さだけ離間すると共に、該内扉を開放した際には前記規制体が前記氷取出口の下部内周縁に当接するよう位置決めされていることを特徴とする。
前記課題を克服し、所期の目的を好適に達成するため本願の別の発明に係る貯氷庫は、
内部に氷塊を貯留する筐体と、該筐体に下端部が回動可能に配設され、その上端部を筐体に対して近接・離間するよう回動することで該筐体に開設した氷取出口を開閉する外扉と、この外扉の裏面と対向する氷案内板の幅方向両側に筐体の両内側壁と対向する一対の側板を備え、両側板の下部に設けた回動支持部を介して両内側壁間に回動自在に枢支され、前記外扉の回動に追従して回動して氷取出口を開閉する内扉とからなる貯氷庫において、
前記内扉における氷案内板の前面下部に、幅方向に長い長方形状の板部材を断面コ字状となるよう屈曲成形して前面側に突出すると共に、短手方向の一端に設けたフランジを介して氷案内板に配設される規制体が設けられ、
前記規制体のコ字状部分には、該規制体の短手方向に延在するスリットが幅方向に離間して複数形成され、
前記内扉は、該内扉を閉成した際には前記規制体が前記氷取出口の下部内周縁に対し庫内への手指等の挿入を許容する長さだけ離間すると共に、該内扉を開放した際には前記規制体が前記氷取出口の下部内周縁に当接するよう位置決めされていることを特徴とする。
【００１１】
【発明の実施の形態】
次に、本発明に係る貯氷庫につき、好適な実施例を挙げて、添付図面を参照しながら以下説明する。なお、従来の技術で説明した部材と同一の部材に関しては、同一の符号を付すと共にその詳細な説明は省略する。
【００１２】
図１に示す如く、実施例に係る貯氷庫１０に配設される内扉１２は、前述したように、筐体２８に回動自在に枢支された外扉１８の裏面と対向する氷案内板１２ａと、該氷案内板１２ａの幅方向両側に配設されて筐体２８における内箱２６の両内側壁と対向する一対の側板１２ｂ,１２ｂと、両側板１２ｂ,１２ｂの下部に設けた回動支持部としての取付孔１２ｃ,１２ｃとから基本的に構成され、両取付孔１２ｃ,１２ｃに、内箱２６の対応位置に設けた支持部３６,３６を係合することで、当該内扉１２は筐体２８(内箱２６)に回動に枢支される。この内扉１２における氷案内板１２ａの前面下部には、前面側に所要高さで突出する規制体１６が設けられている。この規制体１６は、図２に示すように、長方形状の板部材をその短手方向の略中央部で鈍角の山型に屈曲してなるものであって、このように成形された別部材としての規制体１６が、氷案内板１２ａにネジまたは接着等の手段により取付けられている。また規制体１６は、その幅寸法が、前記氷案内板１２ａの対応する幅寸法(両側板１２ｂ,１２ｂ間の長さ)よりも若干短く設定されるが、後述する開放状態において、内箱２６の両内側壁と規制体１６の幅方向両端との間に生ずる隙間から氷塊４０が外部にこぼれ出ることはないよう構成してある。なお、規制体１６の幅寸法に関しては、前記氷取出口３０の内部幅寸法より僅かに短かい寸法に設定して、内箱２６の両内側壁と規制体１６の幅方向両端との間に生ずる隙間を小さくすることが推奨される。
【００１３】
前記内箱２６の両内側壁に設けられる支持部３６,３６は内箱２６と一体に成形されたものであって、その位置は、前記氷取出口３０の下部内周縁から離間した位置に設定されている。そして、この支持部３６,３６を介して内箱２６に回動自在に枢支される内扉１２は、図１(ａ)に示すように、該内扉１２を閉成した際には前記規制体１６が前記氷取出口３０の下部内周縁から所定長さだけ離間すると共に、図１(ｂ)に示すように、該内扉１２を開放した際には前記規制体１６が前記氷取出口３０の下部内周縁に当接するよう位置決めされる。なお、内扉１２を閉成した際における規制体１６と氷取出口３０の下部内周縁との離間間隔は、庫内への手指等の挿入を許容する長さに設定されている。また前記規制体１６は、内扉１２が前記ホルダ３８によって外扉１８と共に強制的に開放方向に回動される際には、外扉１８を閉成した状態で該規制体１６と氷取出口３０の下部内周縁との間に生じる間隙部分に介在している氷塊４０に対して上方から当接してこれを貯氷室内に押し戻すよう構成される。なお、外扉１８はパッキンを介して氷取出口３０を密閉するよう構成してあるから、前記規制体１６と氷取出口３０の下部内周縁との間に生じる間隙部分から庫内の冷気が外部に洩れることはない。
【００１４】
前記内箱２６における一方の内側壁には、図３に示す如く、前記支持部３６,３６の上方でかつ内扉１２の上端における回動軌跡に臨む位置にストッパ２０が一体に突設されている。このストッパ２０は、前記外扉１８を開放した状態で、内扉１２のみ閉成方向に回動した際に、該内扉１２を略垂直姿勢に保持して庫内側への傾倒を防止するべく機能する。なお内箱２６の両内側壁に、対向的にストッパ２０,２０を設けてもよい。
【００１５】
【実施例の作用】
次に、前述した貯氷庫の作用につき説明する。この貯氷庫１０では、図１(ａ)に示すように、前記筐体２８の氷取出口３０を前記外扉１８で閉成した状態において、前記内扉１２の氷案内板１２ａに設けられた前記規制体１６は、氷取出口３０の下部内周縁から離間している。このとき氷案内板１２ａの下端は、氷取出口３０の下部内周縁よりも低い位置に到来しているため、貯氷室に貯留されている氷塊４０の一部が、規制体１６と氷取出口３０との間隙部分から筐体２８の外部にこぼれ出ることはない。
【００１６】
この状態から前記外扉１８を筐体２８の前方に回動することにより、前述した如く、該外扉１８の裏面に配設した前記ホルダ３８が、内扉１２における氷案内板１２ａの上端と係合して、該内扉１２を筐体２８の前方に一体的に回動させる。そして、回動途次における所定位置まで外扉１８が回動すると、氷案内板１２ａからホルダ３８が離脱するが、内扉１２はこれ以後も、その自重によって氷案内板１２ａの上端が外扉１８の裏面を摺動しつつ一体的に回動する。そして外扉１８が回動終点に達すると、内扉１２も同様にその回動終点に達する。このとき内扉１２に設けた前記規制体１６は、図１(ｂ)に示すように、前記氷取出口３０の下部内周縁に当接する。なお、内扉１２を開放する前の状態では、規制体１６と氷取出口３０の下部内周縁との間に生じる間隙部分に、貯氷室内に貯留された一部の氷塊４０が介在している場合もあるが、内扉１２が前記ホルダ３８によって外扉１８と共に強制的に回動されることにより、当該氷塊４０に対して前記規制体１６が上方から回動当接して貯氷室内に押し戻し、開放に支障を来たすことはない。
【００１７】
前記外扉１８および内扉１２を開放した際には、前記氷取出口３０の下部内周縁に規制体１６が当接して両者３０,１６間の間隙は略全面的に閉成されるから、作業者が氷塊４０を取出すためにスコップ等を氷塊群に差込む圧力により該氷塊群が押された場合であっても、氷取出口３０と内扉１２との間から氷塊４０が外部にこぼれ落ちるのは確実に防止される。また内扉１２を開放することによって、前述した如く、氷案内板１２ａの上面に氷塊４０が案内放出されることになるが、該氷案内板１２ａは規制体１６によって剛性が向上していると共に、該規制体１６が氷取出口３０の下部内周縁に当接しているので、氷塊４０の自重では容易に湾曲することがない。更には、氷塊４０と共に例えば使用者が内扉１２を手等で押圧することもあり得るが、この場合であっても、該案内板１２ａ自体がこの押圧力に耐え得るようになっている。
【００１８】
ここで、前記支持部３６,３６を氷取出口３０から所定距離だけ離間した位置に設けると共に、前記内扉１２に規制体１６を配設していない場合には、内扉１２の氷案内板１２ａに多数の氷塊４０が載置されると、図４に示す如く、その荷重によって該氷案内板１２ａ全体が下方に向けて湾曲すると共に、両側板１２ｂ,１２ｂが内箱２６の両内側壁から離間する内側に向けて傾動する。このため両側板１２ｂ,１２ｂと内箱２６の両内側壁との間に生じる隙間を介して、貯氷室に貯留されている氷塊４０の一部がこぼれ出る懸念がある。しかるに、実施例のように内扉１２の氷案内板１２ａに規制体１６を配設したことにより、該氷案内板１２ａの剛性が向上し、かつ規制体１６が氷取出口３０の下部内周縁に当接するので撓みが好適に防止される。すなわち、両側板１２ｂ,１２ｂが内箱２６の両内側壁から殆ど離間しないため、両者の間から氷塊４０がこぼれ出るのは防止される。
【００１９】
前記外扉１８を開放した状態で内扉１２のみを閉成方向に回動させ、前記氷案内板１２ａを内箱２６に設けた前記ストッパ２０に当接させることにより、図３に示す如く、内扉１２は氷取出口３０の内側で略垂直姿勢に保持される。このとき前記規制体１６と氷取出口３０の下部内周縁との間には、前述したように、手指等を挿入するのに必要充分な間隙が生じるため、該内扉１２を内箱２６から取外すことなく、氷取出口３０の下部内周縁や内扉１２との間の部分を容易に清掃することができる。また、前記氷案内板１２ａに規制体１６を設けることで、筐体２８に対する内扉１２の枢支位置(支持部３６,３６の配設位置)を氷取出口３０の下部内周縁から離間する位置に設定することができるから、内箱２６を一体成形しても支持部３６,３６の成形部位を良好に仕上げ得る。従って、内箱２６自体の清掃も容易となる。
【００２０】
前記内扉１２の全面清掃や交換作業を行なうに際して該内扉１２を内箱２６から取外す場合は、手指等で前記側板１２ｂ,１２ｂを把持した状態で、これらを相互に近接させることで、前記支持部３６,３６を取付孔１２ｃ,１２ｃから離脱させる。この場合に、支持部３６,３６は氷取出口３０の下部内周縁から離間する位置に設けられているから、この取外しあるには逆の取付け作業を容易に行ない得る。なお、内扉１２の取外しおよび取付けに際しては、氷案内板１２ａを湾曲させる必要があるので、その湾曲を容易とするために、前記規制体１６にスリットを設けたり、厚みを適宜設定することが推奨される。
【００２１】
【別実施例】
図５〜図９は、内扉１２に設けられる規制体の別実施例を示すものであって、図５に示す第１別実施例では、基本的には実施例と同じく構成された規制体５０に、幅方向に所定間隔で複数のスリット２２を設け、氷案内板１２ａの剛性を向上しつつ湾曲を許容し得るよう構成してある。すなわち、規制体５０を配設することにより氷案内板１２ａの剛性が向上することで、前記支持部３６,３６に対する内扉１２の取付けや取外しが困難とならないようになっている。なお、氷案内板１２ａに対して幅寸法の短かい複数の規制体を、幅方向に所定間隔離間して配設することでも、第１別実施例と同様の効果を奏する。
【００２２】
図６に示す第２別実施例に係る規制体５２は、前記氷案内板１２ａとは別体の板部材を略Ｌ字形状に形成したものであって、図に示すように、一方の屈曲片５２ａを氷案内板１２ａの幅方向に沿って取付けることで、他方の屈曲片５２ｂを該氷案内板１２ａと直交方向して立上がるようにしている。また各屈曲片５２ａ,５２ｂのうち、少なくとも氷案内板１２ａと直交する他方の屈曲片５２ｂは、その高さが、前記内扉１２を閉成した際(またはストッパ２０で位置規制された状態)に前記氷取出口３０の下部内周縁から所要長さだけ離間すると共に、該内扉１２をその回動終点まで開放した際には、該氷取出口３０の下部内周縁に突出端部が当接するよう設定されている。
【００２３】
図７に示す第３別実施例に係る規制体５４は、前記内扉１２の下端から上端に向けて所要角度で延在するよう一体的に成形された板状のものである。すなわちこの規制体５４は、前記氷案内板１２ａ自体の一端部を該規制体５４の長さ分だけ予め加えた寸法で成形しておき、これを該氷案内板１２ａの前面に向けて所定角度で折返すことで形成される。なお規制体５４の長さは、氷案内板１２ａの対応する長さよりも充分短い寸法に設定されている。また規制体５４が氷案内板１２ａに対して傾斜する角度は、該規制体５４の開放端部と氷案内板１２ａとの離間幅が所定寸法となるよう設定される。すなわちこの所定寸法とは、前記内扉１２を閉成した際(またはストッパ２０で位置規制された状態)に、該規制体５４が前記氷取出口３０の下部内周縁から所要長さだけ離間すると共に、該内扉１２をその回動終点まで開放した際には、該氷取出口３０の下部外周縁に該規制体５４の開放端部近傍が当接する寸法である。
【００２４】
図８に示す第４別実施例に係る規制体５６は、長方形状の板部材を断面コ字状となるよう屈曲成形すると共に、短手方向の一端にフランジ５６ａを成形し、該フランジ５６ａを介して内扉１２の氷案内板１２ａに配設されている。この規制体５６は、その幅寸法が、前記氷案内板１２ａの対応する幅寸法(両側板１２ｂ,１２ｂ間の長さ)よりも若干短く、また短手方向に沿って屈曲成型されるコ字状部分の長さ寸法が、氷案内板１２ａの対応する長さ寸法(上下端間の長さ)よりも充分短く設定される。そしてコ字状部分の高さは、前記内扉１２を閉成した際(またはストッパ２０で位置規制された状態)に、該規制体５６が前記氷取出口３０の下部内周縁から所要長さだけ離間すると共に、該内扉１２をその回動終点まで開放した際には、該氷取出口３０の下部内周縁に該コ字状部分の開放端部が当接する寸法に設定されている。なお規制体５６のコ字状部分には、図に示す如く、幅方向に所定間隔で複数のスリット２２が設けられており、このスリット２２によって内扉１２の前記支持部３６,３６に対する取付けおよび取外し作業を容易化するよう構成してある。
【００２５】
図９に示す第５別実施例に係る規制体５８は、前記氷案内板１２ａの下部近傍を、前面側に突出する断面山型に一体成形したものである。この規制体５８の形状自体は、第１別実施例の規制体５０と略同一に設定されたものであって、この規制体５８が前記側板１２ｂ,１２ｂの突出方向とは逆方向に向けて突出成形されている。この規制体５８も、前述したように、その高さが前記内扉１２を閉成した際(またはストッパ２０で位置規制された状態)に、該規制体５８が前記氷取出口３０の下部内周縁から所要長さだけ離間すると共に、該内扉１２をその回動終点まで開放した際には、該氷取出口３０の下部周縁に該規制体５８の突出端部が当接する寸法に設定されている。
【００２６】
なお、本発明に係る貯氷庫は、自動製氷機に一体的に構成されて、該製氷機の製氷部で製造された氷塊を貯留するものであっても、また自動製氷機とは別体で構成されて、別場所の製氷部で製造した氷塊を貯留するものであってもよい。また実施例では、内箱の両内側壁に突状の支持部を設けると共に、内扉の側板に取付孔を形成して両者を回動自在に係合するよう構成したが、内扉の側板に回動支持部としての突起を設けると共に、内箱の流内側壁に対応する凹部を形成したものであってもよい。
【００２７】
【発明の効果】
以上説明した如く、本発明に係る貯氷庫では、筐体に回動自在に枢支した内扉において、該内扉を閉成した際には規制体が氷取出口の下部内周縁から所定長さだけ離間すると共に、該内扉を開放した際には規制体が氷取出口の下部内周縁に当接するよう位置決めしたので、内扉を開放した際には、該内扉と氷取出口の下部内周縁との間に隙間は生じないから、庫内に貯留されている氷塊が内扉と氷取出口の下部内周縁との間から外部にこぼれ出るのを確実に防止し得る。また内扉を閉成したときには、規制体と氷取出口の下部内周縁との間に手指等を挿入するのに必要充分な間隙が生ずるので、内扉を筐体から取外すことなく、氷取出口の下部内周縁や内扉との間の部分を容易に清掃することができ、作業時間を短縮し得る。更には、氷案内板に規制部を設けることで該氷案内板自体の剛性が向上すると共に、内扉を開放した際には規制部が氷取出口の下部内周縁に当接するよう構成したから、多くの氷塊が載った場合であっても湾曲することはなく、湾曲に伴う氷塊のこぼれ落ちも防止し得る。また、規制体にスリットを設けることで氷案内板の湾曲を許容し、内扉の取付けや取外しが困難となることはない。

BACKGROUND OF THE INVENTION
The present invention relates to an ice storage, and more specifically, when an inner and outer door for taking out ice disposed in the ice storage is opened, ice blocks stored in the storage are not spilled from a gap of the inner door. It relates to the ice storage.
[0002]
[Prior art]
An automatic ice making machine that stores ice blocks continuously manufactured in an ice making unit in an ice storage is suitably used in facilities such as a coffee shop and a restaurant and other kitchens. Since the present invention relates to an ice storage employed in the automatic ice making machine, an outline of the ice storage will be described with reference to FIG.
[0003]
The ice storage 10 shown in the figure has as its main body a housing 28 composed of an outer box 24 molded into a required shape, an inner box 26 and a heat insulating material 27 filled between both boxes 24, 26. In addition, an ice storage chamber for storing a required amount of ice blocks 40 is defined, and an ice take-out port 30 for taking out ice is provided in the front portion of the housing 28. In addition, a hinge 32 is disposed on the front surface of the housing 28 below the ice outlet 30, and the outer door 18 is pivotally supported on the hinge 32 so that the lower end portion thereof is rotatable. Then, the ice take-out port 30 is opened and closed by rotating the upper end portion of the outer door 18 via a hinge 32 so as to approach and separate from the front surface of the housing 28. Note that the housing 28 in the illustrated example is provided with an opening in the upper part of the rear wall or the side wall in order to receive ice blocks emitted from an ice making unit (not shown) provided at the rear or side of the housing 28. However, the top part may be completely opened in order to receive ice blocks emitted from the ice making part disposed above the housing 28.
[0004]
An inner door 12 that rotates following the rotation of the outer door 18 and opens and closes the ice outlet 30 is disposed inside the housing 28. The inner door 12 is a bowl-shaped member having a substantially U-shaped cross section, and guides the ice block 40 stored in the ice storage chamber (inside the cabinet) to the front side of the housing 28. It is basically composed of a plate 12a and side plates 12b and 12b which are erected so as to be substantially orthogonal to both ends of the ice guide plate 12a in the width direction. On both inner side walls in the width direction of the inner box 26 of the housing 28, a pair of support portions 36 projecting horizontally so as to face each other at a position spaced apart from the lower inner periphery of the ice outlet 30 by a predetermined distance in the cabinet. 36 is arranged. Then, the inner door 12 can be pivotally engaged with mounting holes (rotating support portions) 12c and 12c formed in the lower portions of the side plates 12b and 12b so that the inner door 12 can be pivoted. It is pivotally supported with respect to. Further, the upper end of the ice guide plate 12a in the inner door 12 is configured to be detachably engaged with a holder 38 having an L-shaped cross section disposed on the back surface of the outer door 18.
[0005]
When the outer door 18 closes the ice outlet 30, the inner door 12 is supported at a substantially vertical position with the upper end engaged with the holder 38 as shown in FIG. Yes. Then, by rotating the outer door 18 so that the upper end portion of the outer door 18 is tilted toward the front of the housing 28 from this state, the inner door 12 is placed in the state where the upper end is engaged with the holder 38. It follows the door 18 and rotates integrally. At this time, since the inner door 12 rotates around a rotation fulcrum different from the outer door 18, the holder 38 of the outer door 18 and the upper end of the inner door 12 move away from each other as the rotation occurs. When the outer door 18 is rotated to a predetermined position, the holder 38 is detached from the upper end of the inner door 12. Further, when the outer door 18 is rotated to the rotation end point, the inner door 12 is tilted forward of the housing 28 integrally with the outer door 18 while sliding the upper end along the back surface of the outer door 18. The ice outlet 30 is opened as shown in FIG.
[0006]
When the outer door 18 is turned to the turning end point, the inner door 12 stops at a position where the ice guide plate 12a is substantially parallel to the outer door 18, as shown in FIG. At the same time, the pair of side plates 12b, 12b faces in a state extending from the inside of the warehouse to the outside of the warehouse. As a result, the ice block 40 stored in the ice storage chamber is guided to the front side of the housing 28 by the ice guide plate 12a, and is prevented from spilling from the ice outlet 30 to the outside side by the side plates 12b and 12b. .
[0007]
[Problems to be solved by the invention]
In the ice storage 10 described above, when the inner door 12 is opened, the gap between the ice guide plate 12a and the lower inner peripheral edge of the ice take-out port 30 is not formed. The support portions 36 and 36 that pivotally support the inner door 12 are set at positions that are extremely close to the ice outlet 30 in the inner box 26. For this reason, when the support portions 36 and 36 are integrally formed with the inner box 26, not only a good finish cannot be expected at the connection portion between the support portions 36 and 36 and the inner box 26, but also the inner door with respect to the inner box 26. There was a fault that the attachment of 12 became difficult. Therefore, conventionally, the inner box 26 is constituted by connecting a plurality of plate members to each other, and the support portions 36 and 36 are also arranged by retrofitting. For example, a cylindrical projecting portion is bonded to a place where the support portions 36 and 36 are to be provided in a horizontally opposed manner, or a hole is provided in the inner box 26, and a shaft or screw for attaching the support portion 36 to the hole A fastening member such as the above is disposed. However, in this case, the number of parts is inevitably increased, resulting in a cost increase. Further, when the inner door 12 is removed from the inner box 26 for cleaning or the like, these fastening members and the like must be removed from the inner box 26, and it is pointed out that it takes much time and labor. The Furthermore, since the inner box 26 is not integrally molded, it is difficult to clean the joints and corners of each plate material.
[0008]
In addition, by providing a bulging portion at the front lower portion of the inner door 12, regardless of whether the inner door 12 is open or closed, the bulging portion is always close to the lower inner peripheral end of the ice outlet 30, There is a proposal to separate the pivot position between the inner door 12 and the inner box 26 from the lower inner peripheral end of the ice outlet 30. However, in this case, since the bulging portion is always close to the lower inner peripheral edge of the ice outlet 30, it is extremely difficult to clean the portion, and the complicated work of removing the inner door 12 from the inner box 26 is required for cleaning. Was needed.

DETAILED DESCRIPTION OF THE INVENTION
Next, a preferred embodiment of the ice storage according to the present invention will be described below with reference to the accompanying drawings. In addition, about the same member as the member demonstrated by the prior art, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.
[0012]
As shown in FIG. 1, the inner door 12 disposed in the ice storage 10 according to the embodiment is, as described above, the ice guide facing the back surface of the outer door 18 pivotally supported by the housing 28. A plate 12a, a pair of side plates 12b, 12b disposed on both sides in the width direction of the ice guide plate 12a and facing both inner side walls of the inner box 26 in the housing 28, and provided below the side plates 12b, 12b. It is basically composed of mounting holes 12c and 12c as rotation support parts, and by engaging the support parts 36 and 36 provided at corresponding positions of the inner box 26 with both the mounting holes 12c and 12c, the inner holes The door 12 is pivotally supported by the housing 28 (inner box 26). In the lower part of the front surface of the ice guide plate 12a in the inner door 12, a restricting body 16 that protrudes at a required height is provided on the front surface side. As shown in FIG. 2, the regulating body 16 is formed by bending a rectangular plate member into an angled mountain shape at a substantially central portion in the short side direction, and is formed in such a separate member. The regulating body 16 is attached to the ice guide plate 12a by means of screws or adhesion. The width of the restricting body 16 is set slightly shorter than the corresponding width of the ice guide plate 12a (the length between the side plates 12b and 12b). The ice lump 40 is configured not to spill out to the outside from a gap formed between both inner side walls and both ends in the width direction of the regulating body 16. The width of the restricting body 16 is set to be slightly shorter than the internal width of the ice take-out port 30 and is generated between both inner side walls of the inner box 26 and both ends of the restricting body 16 in the width direction. It is recommended to reduce the gap.
[0013]
The support portions 36, 36 provided on both inner side walls of the inner box 26 are formed integrally with the inner box 26, and the position thereof is set at a position separated from the lower inner peripheral edge of the ice outlet 30. ing. When the inner door 12 is pivotally supported by the inner box 26 via the support portions 36, 36, as shown in FIG. The restricting body 16 is separated from the lower inner peripheral edge of the ice take-out port 30 by a predetermined length, and when the inner door 12 is opened as shown in FIG. It positions so that it may contact | abut to the lower inner periphery of this. Note that the spacing between the regulating body 16 and the lower inner periphery of the ice outlet 30 when the inner door 12 is closed is set to a length that allows insertion of fingers or the like into the cabinet. Further, when the inner door 12 is forcibly rotated together with the outer door 18 by the holder 38 in the opening direction, the regulating body 16 and the ice take-out port 30 are in a state where the outer door 18 is closed. It is configured to abut against the ice block 40 interposed in the gap portion formed between the lower inner peripheral edge and push it back into the ice storage chamber. In addition, since the outer door 18 is configured to seal the ice take-out port 30 through packing, the cool air in the cabinet is exposed to the outside from a gap portion formed between the regulating body 16 and the lower inner peripheral edge of the ice take-out port 30. There is no leakage.
[0014]
On one inner wall of the inner box 26, as shown in FIG. 3, a stopper 20 is integrally projected above the support portions 36 and 36 at a position facing the turning locus at the upper end of the inner door 12. Yes. When the outer door 18 is opened and only the inner door 12 is rotated in the closing direction, the stopper 20 holds the inner door 12 in a substantially vertical posture to prevent the inner door 12 from tilting toward the inside. Function. In addition, you may provide the stoppers 20 and 20 on both the inner walls of the inner box 26 facing each other.
[0015]
[Effect of the embodiment]
Next, the operation of the above-described ice storage will be described. In the ice storage 10, as shown in FIG. 1A, the ice guide plate 12a of the inner door 12 is provided with the ice outlet 30 of the housing 28 closed by the outer door 18. The regulating body 16 is separated from the lower inner periphery of the ice outlet 30. At this time, the lower end of the ice guide plate 12a has arrived at a position lower than the lower inner peripheral edge of the ice take-out port 30, so that a part of the ice block 40 stored in the ice storage chamber may be No spills out of the housing 28 from the gap portion.
[0016]
By rotating the outer door 18 to the front of the housing 28 from this state, the holder 38 disposed on the back surface of the outer door 18 is connected to the upper end of the ice guide plate 12a in the inner door 12 as described above. By engaging, the inner door 12 is integrally rotated in front of the housing 28. Then, when the outer door 18 rotates to a predetermined position in the course of rotation, the holder 38 is detached from the ice guide plate 12a. However, the inner door 12 will continue to have the upper end of the ice guide plate 12a kept on the outer door due to its own weight. It rotates integrally while sliding the back surface of 18. When the outer door 18 reaches the rotation end point, the inner door 12 similarly reaches the rotation end point. At this time, the regulating body 16 provided on the inner door 12 abuts against the lower inner periphery of the ice outlet 30 as shown in FIG. In a state before the inner door 12 is opened, a part of the ice block 40 stored in the ice storage chamber is interposed in a gap portion formed between the regulating body 16 and the lower inner periphery of the ice outlet 30. However, when the inner door 12 is forcibly rotated together with the outer door 18 by the holder 38, the regulating body 16 is brought into rotational contact with the ice block 40 from above and pushed back into the ice storage chamber to be opened. There will be no hindrance.
[0017]
When the outer door 18 and the inner door 12 are opened, the regulating body 16 comes into contact with the lower inner peripheral edge of the ice outlet 30 and the gap between the two is closed substantially entirely. Even when the ice block is pushed by the pressure of inserting a scoop or the like into the ice block to remove the ice block 40, the ice block 40 spills out from between the ice outlet 30 and the inner door 12. Is definitely prevented. Further, by opening the inner door 12, as described above, the ice block 40 is guided and released to the upper surface of the ice guide plate 12a. The ice guide plate 12a is improved in rigidity by the regulating body 16. Since the regulating body 16 is in contact with the lower inner peripheral edge of the ice outlet 30, it is not easily bent by the weight of the ice block 40. Further, for example, the user may press the inner door 12 with his / her hand together with the ice block 40, but even in this case, the guide plate 12a itself can withstand this pressing force.
[0018]
Here, when the support portions 36 and 36 are provided at a position separated from the ice outlet 30 by a predetermined distance, and the regulating body 16 is not disposed on the inner door 12, the ice guide plate 12a of the inner door 12 is provided. 4, the ice guide plate 12a is bent downward by the load as shown in FIG. 4, and the side plates 12b and 12b are separated from both inner side walls of the inner box 26. Tilt toward the inside away. For this reason, there is a concern that a part of the ice lump 40 stored in the ice storage chamber spills out through a gap formed between the both side plates 12b, 12b and the inner side walls of the inner box 26. However, by providing the restricting body 16 on the ice guide plate 12a of the inner door 12 as in the embodiment, the rigidity of the ice guide plate 12a is improved, and the restricting body 16 is placed on the lower inner periphery of the ice outlet 30. Since it contacts, bending is prevented suitably. That is, since both side plates 12b and 12b are hardly separated from both inner side walls of the inner box 26, it is possible to prevent the ice block 40 from spilling out between them.
[0019]
As shown in FIG. 3, by rotating only the inner door 12 in the closing direction with the outer door 18 opened, and bringing the ice guide plate 12a into contact with the stopper 20 provided in the inner box 26, The inner door 12 is held in a substantially vertical posture inside the ice outlet 30. At this time, as described above, there is a sufficient gap between the regulating body 16 and the lower inner peripheral edge of the ice outlet 30 to insert a finger or the like. Therefore, the inner door 12 is removed from the inner box 26. The portion between the lower inner peripheral edge of the ice outlet 30 and the inner door 12 can be easily cleaned. In addition, by providing the ice guide plate 12 a with the regulating body 16, the pivot position of the inner door 12 with respect to the housing 28 (position where the support portions 36 and 36 are disposed) is separated from the lower inner periphery of the ice outlet 30. Therefore, even if the inner box 26 is integrally molded, the molding portions of the support portions 36 and 36 can be satisfactorily finished. Accordingly, the inner box 26 itself can be easily cleaned.
[0020]
When removing the inner door 12 from the inner box 26 when cleaning the entire surface of the inner door 12 or replacing the inner door 12, the side plates 12b and 12b are held close to each other with fingers or the like, The support portions 36 and 36 are detached from the mounting holes 12c and 12c. In this case, since the support portions 36 and 36 are provided at positions separated from the lower inner peripheral edge of the ice outlet 30, it is possible to easily perform a reverse mounting operation for removal. When removing and attaching the inner door 12, it is necessary to curve the ice guide plate 12a. Therefore, in order to facilitate the curve, a slit may be provided in the regulating body 16 or the thickness may be set appropriately. Recommended.
[0021]
[Another example]
5 to 9 show another embodiment of the restricting body provided on the inner door 12, and in the first another embodiment shown in FIG. 5, the restricting body basically configured in the same manner as the embodiment. 50 is provided with a plurality of slits 22 at predetermined intervals in the width direction so as to allow bending while improving the rigidity of the ice guide plate 12a. In other words, the provision of the regulating body 50 improves the rigidity of the ice guide plate 12a, so that it is not difficult to attach or remove the inner door 12 to or from the support portions 36, 36. It is to be noted that the same effect as that of the first alternative embodiment can be obtained by arranging a plurality of regulating bodies having a short width with respect to the ice guide plate 12a at a predetermined interval in the width direction.
[0022]
The regulating body 52 according to the second alternative embodiment shown in FIG. 6 is obtained by forming a plate member separate from the ice guide plate 12a into a substantially L shape, and as shown in the figure, By attaching the piece 52a along the width direction of the ice guide plate 12a, the other bent piece 52b rises in a direction orthogonal to the ice guide plate 12a. Of the bent pieces 52a and 52b, at least the other bent piece 52b orthogonal to the ice guide plate 12a has a height when the inner door 12 is closed (or a state where the position is restricted by the stopper 20). When the inner door 12 is opened to the end of its rotation, the projecting end is brought into contact with the lower inner peripheral edge of the ice outlet 30. Is set.
[0023]
The restricting body 54 according to the third alternative embodiment shown in FIG. 7 is a plate-like member that is integrally formed so as to extend at a required angle from the lower end to the upper end of the inner door 12. That is, the restricting body 54 is formed with a dimension in which one end of the ice guide plate 12a itself is added in advance by the length of the restricting body 54, and this is directed toward the front surface of the ice guide plate 12a at a predetermined angle. It is formed by turning back at. The length of the regulating body 54 is set to a dimension that is sufficiently shorter than the corresponding length of the ice guide plate 12a. Further, the angle at which the restricting body 54 is inclined with respect to the ice guide plate 12a is set such that the separation width between the open end portion of the restricting body 54 and the ice guide plate 12a becomes a predetermined dimension. That is, the predetermined dimension means that when the inner door 12 is closed (or in a state where the position is regulated by the stopper 20), the regulating body 54 is separated from the lower inner peripheral edge of the ice outlet 30 by a required length. When the inner door 12 is opened to its end of rotation, the vicinity of the open end of the regulating body 54 is in contact with the lower outer periphery of the ice outlet 30.
[0024]
The regulating body 56 according to the fourth alternative embodiment shown in FIG. 8 is formed by bending a rectangular plate member so as to have a U-shaped cross section, and by forming a flange 56a at one end in the short-side direction. The ice guide plate 12a of the inner door 12 is disposed. The restriction body 56 has a width dimension slightly shorter than the corresponding width dimension of the ice guide plate 12a (the length between the side plates 12b and 12b), and is a U-shape that is bent and formed along the short direction. The length dimension of the shaped part is set sufficiently shorter than the corresponding length dimension (the length between the upper and lower ends) of the ice guide plate 12a. The height of the U-shaped portion is such that when the inner door 12 is closed (or in a state where the position is restricted by the stopper 20), the restricting body 56 has a required length from the lower inner peripheral edge of the ice outlet 30. When the inner door 12 is opened to the end of rotation, the dimension is set such that the open end of the U-shaped portion contacts the lower inner peripheral edge of the ice outlet 30. The U-shaped portion of the restricting body 56 is provided with a plurality of slits 22 at predetermined intervals in the width direction as shown in the figure, and the slits 22 are used to attach the inner door 12 to the support portions 36 and 36. It is configured to facilitate the removal work.
[0025]
A regulating body 58 according to a fifth alternative embodiment shown in FIG. 9 is formed by integrally molding the vicinity of the lower portion of the ice guide plate 12a into a cross-sectional mountain shape projecting to the front side. The shape of the restricting body 58 is set to be substantially the same as that of the restricting body 50 of the first alternative embodiment, and the restricting body 58 faces in the direction opposite to the protruding direction of the side plates 12b and 12b. Protrusion molding. As described above, when the inner door 12 is closed (or the position is restricted by the stopper 20), the restricting body 58 also has a lower inner peripheral edge of the ice outlet 30. When the inner door 12 is opened to the end of rotation, the dimension is set such that the projecting end of the regulating body 58 contacts the lower peripheral edge of the ice outlet 30 when the inner door 12 is opened to its end of rotation. .
[0026]
Note that the ice storage according to the present invention is configured integrally with an automatic ice maker and stores ice blocks produced by the ice making unit of the ice maker, or separately from the automatic ice maker. It is comprised and the ice block manufactured in the ice-making part of another place may be stored. Further, in the embodiment, the projecting support portions are provided on the both inner side walls of the inner box, and the mounting holes are formed in the side plates of the inner door so that both of them can be freely rotated. In addition to providing a protrusion as a rotation support portion, a recess corresponding to the inner wall of the inner box may be formed.
[0027]
【The invention's effect】
As described above, in the ice storage according to the present invention, in the inner door pivotally supported by the housing, when the inner door is closed, the regulating body has a predetermined length from the lower inner peripheral edge of the ice outlet. When the inner door is opened, the regulating body is positioned so as to contact the lower inner peripheral edge of the ice outlet, so when the inner door is opened, the lower inner peripheral edge of the inner door and the ice outlet is opened. Therefore, it is possible to reliably prevent the ice blocks stored in the warehouse from spilling out from between the inner door and the lower inner peripheral edge of the ice outlet. In addition, when the inner door is closed, there is a sufficient gap between the regulator and the lower inner periphery of the ice outlet to insert fingers, etc., so the ice door can be removed without removing the inner door from the housing. The portion between the lower inner periphery and the inner door can be easily cleaned, and the working time can be shortened. Furthermore, since the ice guide plate itself is provided with a restriction portion, the rigidity of the ice guide plate itself is improved, and when the inner door is opened, the restriction portion is configured to come into contact with the lower inner periphery of the ice outlet. Even when a large number of ice blocks are placed, they are not curved and it is possible to prevent spilling of ice blocks accompanying the curve. Further, by providing a slit in the restricting body, the ice guide plate is allowed to be curved, and it is not difficult to attach or remove the inner door.
