Description

【0001】
【発明の属する技術分野】
本発明は、自動製氷機の製氷機構部、特にその製氷部ケースの氷塊を送り出す開口に設けるセパレータの改良に関する。
【0002】
【従来の技術】
この種の自動製氷機では、例えば特開昭60−89659号公報に開示されているように、製氷機本体8の上部に設けられた製氷機構部は、製氷運転中は冷却パイプ5により冷却されている製氷カップ4に下方の散水器16から噴出される製氷水を受けて氷結させ、氷結が完了すれば製氷運転を停止し、冷却パイプ5にホットガスを供給して製氷カップ4内に生成された氷塊を傾斜したスロープ13上に落下させ、製氷機構部前側の開口を通して下側の貯氷庫10内に落下させるようになっている。製氷機構部前側の開口には重力により垂れ下がった柔軟なシートなどからなる水遮蔽板21を設け、スロープ13を滑り落ちる氷塊は水遮蔽板21を押し開いて貯氷庫10内に落下するが、製氷運転中に散水器16から噴出される製氷水は水遮蔽板21に遮られて貯氷庫10内に入ることはなく、従って貯氷庫10の中の氷塊が溶解されたり、製氷運転の途中で製氷水が不足したりすることはない。
【0003】
上記従来技術の水遮蔽板21は柔軟なシートよりなるものであるが、特開昭60−86876号公報では、短冊状の複数のカーテン4の上部を支持軸4aにより傾斜自在に支持したものが水遮蔽板として開示されている。
【0004】
【発明が解決しようとする課題】
上述した第1の従来技術では水遮蔽板21は全体が一体的に形成されているので、少数の氷塊がスロープ13上に残った場合はその重量だけでは水遮蔽板21を押し開くことができずにスロープ上に残り、散水器16から散水される製氷水により溶けて氷が無駄に消費され、あるいは製氷水の散水の邪魔になるという問題がある。この問題は第2の従来技術のように水遮蔽板を複数のカーテン4に分割して各々の上部を別々に傾斜自在に支持して、1個の氷塊は1個のカーテン4だけを押し開けば貯氷庫10内に落下されるようにすることにより解決することができる。しかしながら、この種の製氷機構部は、内部に設けた散水器(散水ノズル)やスロープ(アイスシュート)などの保守点検のために、製氷機構部の前側の開口に設けた水遮蔽板(セパレータ)を取り外す必要があるが、上述した各従来技術は何れも水遮蔽板を取り外すのが容易ではないので、製氷機構部内部の保守点検に手間がかかるという問題がある。
【0005】
本発明はこのような問題を解決するために各セパレータを複数に分割するとともに着脱自在とし、また複数に分割した各セパレータが僅かの氷塊でも開くように作動を軽くし、さらに各セパレータの取付け誤りによる問題が生じないようにすることを目的とする。
【0006】
【課題を解決するための手段】
このために、本発明による自動製氷機は、前壁の下側に開口を形成した箱状の製氷部ケースと、この製氷部ケース内の下部に取り付けられ製氷水を上方に噴出する噴出口を有する散水ノズルと、製氷部ケース内の上部に取り付けられ下向きに開口されて噴出口から上方に噴出される製氷水を受ける製氷セルを備えるとともに冷却パイプにより冷却される製氷室と、製氷部ケース内の上下方向中間部に傾斜して取り付けられ製氷セルから落下する氷塊を受け止めて斜め前下方に滑らせ開口を通して製氷部ケース内から送り出すアイスシュートと、製氷部ケースに揺動自在に吊下げ支持されて開口を開放自在に閉じるセパレータよりなる製氷機構部を備えてなる自動製氷機において、セパレータを複数に分割するとともに分割された各セパレータは上部が製氷部ケースに離脱可能に係止されていることを特徴とするものである。
【0007】
前項の発明は、前壁の下縁には横方向に伸びる丸棒状の枢支ロッドを一体的に連結し、複数の各セパレータは平板部とその上縁に一体的に形成され枢支ロッドに回動自在に係合される円弧状内面を有するC形断面形状で横方向に伸びる係合部よりなるものとし、各セパレータは係合部を枢支ロッドに係合することにより揺動自在に吊下げ支持することが好ましい。
【0008】
また前項の発明は、各係合部の円弧状内面両端の間の開放部の幅を枢支ロッドの外径より小とし、各係合部は弾性的に変形させて開放部の幅を拡大することにより枢支ロッドに回動自在に係合することが好ましい。
【0009】
また前2項の発明の各係合部は、各セパレータが自然に吊り下げられた状態において開放部が製氷部ケースの外側に向くように枢支ロッドに係合支持することが好ましい。
【0010】
また前項の発明は、前壁の下縁には枢支ロッドとの間で各セパレータと対応する位置に係合部を挿通するスリットをそれぞれ形成し、セパレータには係合部の横幅方向で中心から外れた位置の外周面に円周方向に延びる扇状突起を形成し、スリットには扇状突起と対応する位置に同扇状突起が挿通可能な凹部を形成することが好ましい。
【0011】
また前4項の発明は、互いに隣り合う各セパレータの各平板部の互いに隣接する側縁の少なくとも一方に少なくとも1個の突部を設けることが好ましい。
【0012】
また前5項の発明は、互いに隣り合う各セパレータの各平板部の互いに隣接する側縁の少なくとも一方の先端の厚さを減少させることが好ましい。
【0013】
【発明の実施の形態】
以下に、図1〜図9に示す実施の形態により、本発明の説明をする。この実施の形態の自動製氷機は、図7に示すように、自動製氷機本体70とその内部の上部に設けられた製氷機構部Aなるものである。自動製氷機本体70は、前側板71aと後側板71bと左右の両側板71cと底板71dよりなる機械室71と、断熱性の厚い周壁よりなり上面と前面上半部が開放された箱状で機械室71の上側に支持された貯氷庫72と、貯氷庫72の上面および前面上部をそれぞれ覆う断熱性の天井板73および上部正面板75と、機械室71の前面と貯氷庫72の下部前面を覆う下部正面板74と、下縁部が下部正面板74の上縁にヒンジ76aを介して取り付けられて下部正面板74と上部正面板75の間に形成される開口を開閉する断熱性の扉76よりなり、扉76の上縁と内面の外縁部にはそれぞれ把手76bおよびパッキン76cが取り付けられている。機械室71内には冷却された冷媒を製氷機構部Aに供給するための圧縮機、凝縮器、冷却ファンよりなる冷凍機など(図示省略)が設けられ、また貯氷庫72の底部に設けた排水口72aに連結した排水ホース(図示省略)はこの機械室71内を通って外部に導出されている。
【0014】
製氷機構部Aの製氷部ケースBは左右のブラケット10L,10Rを有しており、各ブラケット10L,10Rの下部より左右両側に突出する張出部10aは後方に突出しており、貯氷庫72の後壁の内面のやや上部に固定した支持部材77にこの張出部10aの突出部を載せ、さらに左右のブラケット10L,10Rを天井板73にボルト止めすることにより、製氷機構部Aは貯氷庫72内の上部に支持されている。張出部10aよりも上方となる製氷機構部Aの後面と貯氷庫72の後壁の間には相当な隙間があり、この部分にはアキュムレータ78、給水や冷媒の配管、電気配線などが設けられている。
【0015】
製氷機構部Aは、図1および図2に示すように、製氷部ケースBと、その下端部に設けられた製氷水タンク30と、製氷部ケースB内の下部と上部と中間部にそれぞれ設けられた散水ノズル40、製氷室50およびアイスシュート60により構成されている。製氷部ケースBは全体として箱状で、主として左右1対のブラケット10L,10Rと、その前後縁を連結する前壁17と後壁20により構成されている。前壁17の上下幅は後壁20よりもかなり小さいので製氷部ケースBの前側の下半部には開口Baが形成され、この開口Baは後述するように開閉自在なセパレータ25により閉じられている。
【0016】
図1および図2に示すように、左右の各ブラケット10L,10Rは、前側から見た形状が全体として上部が外向きに折曲された倒立L字形状で、それぞれの外側には上下方向に延びる複数の補強リブ14a,14bおよび14cが形成されている。各ブラケット10L,10Rの下部には外側に突出して前後方向に水平に延びる内向きコ字断面形状の張出部10aが形成され、張出部10aの下縁と上縁には内側に延びる下フランジ13aと支持突起13bが形成されている。
この張出部10aは後壁20よりも後方に突出し、下フランジ13aと支持突起13bの間に形成されるタンク支持溝11も後壁20より後方に延びている。支持突起13bの上面は後部が上昇するように傾斜され、この上面と間をおいて平行に延びるように各ブラケット10L,10Rに内向きに突出して形成された突出板13cとの間に形成されるノズル支持溝12は、後壁20の手前で止まっている。また突出板13cより上方となる各ブラケット10L,10Rの内面の前後部に形成される円形の支持突起14eは、前側のものの方が後側のものより低く位置している。左ブラケット10Lの下部には、後述するドレンパン37および散水ポンプ45を取り付ける延長部16が一体的に形成され、中間部には2枚の補強リブ14aの間に位置して(図6参照)製氷水を散水ノズル40に送る給水ホース47を通す挿通穴15が形成されている。
【0017】
前壁17はブラケット10L,10Rよりも上下幅がかなり狭い長方形の合成樹脂板であり、その上縁およびやや下部の前側は横方向に延びるリブ17a,17bにより補強されている。またこの前壁17の下縁には横方向に伸びる丸棒状の枢支ロッド18が一体的に形成され、図3および図4に詳細に示すように、この下縁には次に述べる各セパレータ25と対応する位置にスリット19が形成されている。このスリット19はセパレータ25の係合部25bを挿通するものであり、係合部25bに形成した扇状突起26と対応する位置に扇状突起26を挿通可能な凹部19aが形成されている。
【0018】
製氷部ケースBの前側下半部に形成された開口Baは、後述する散水ノズル40の噴出口43および製氷室50の製氷セル52の列数と同じ6個に分割されたセパレータ25により開放自在に閉じられている。主として図3および図4に示すように、各セパレータ25は、縦長長方形の平板部25aと、C形断面形状でその基端側の一側縁が平板部25aの上縁に一体的に連結された横方向に伸びる係合部25bよりなるものである。係合部25bの内面は枢支ロッド18に回動自在に係合される円弧状で、平板部25aに連結される基端側を除く部分の横幅は平板部25aの横幅よりも小さくかつスリット19の長さより僅かに短く、係合部25bの円弧状内面両端の間の開放部25cの幅を枢支ロッド18の外径より小となっている。係合部25bの外周面には、横幅方向で中心から外れた位置に、係合部25bの先端から約90度の範囲にわたり円周方向に延びる扇状突起26が形成されている。
【0019】
このセパレータ25を前壁17に取り付けるには、図8に示すように係合部25bを外側から製氷部ケースB内に入れ、その開放部25cを下側から枢支ロッド18に当て、製氷部ケースB外側の平板部25aを指で挟んで矢印Pに示すように引っ張る。これにより係合部25bは弾性的に変形し開放部25cが一時的に開いて係合部25bの先端側および扇状突起26はスリット19および凹部19a内に入り、図4に示すように係合部25bの円弧状内面が枢支ロッド18の外周面に回動自在に係合されて、各セパレータ25は開放部25cが製氷部ケースBの外側に向く位置となって枢支ロッド18に揺動自在に吊下げ支持され、重力により垂れ下がって製氷部ケースBの前側を閉じる。上述のように、係合部25bに対する扇状突起26の形成位置は、横幅方向で中心から外れているので、セパレータ25は上記と逆向き(図10および図11参照)に前壁17に取り付けることは不可能である。各セパレータ25は、平板部25aを水平近くまで開いて係合部25bの先端部を後向きに押し込むことにより、前壁17から取り外すことができる。
【0020】
後壁20は、製氷部ケースBの後側を実質的に閉じる上下幅を有する長方形の合成樹脂板であり、その上縁は横方向に延びるリブ20aにより補強され、下縁には後方に延びて後述する製氷水タンク30の後部の上側の大部分を覆うカバー21が一体的に形成されている。このカバー21には、製氷水タンク30に製氷水を供給する供給ホースを通すための切欠き(何れも図示省略)が形成されている。
【0021】
これらの各ブラケット10L,10R、前壁17および後壁20は、何れも合成樹脂により一体的に成形されている。この実施の形態では、左右の各ブラケット10L,10Rは、各支持突起14eにシュート支持筒24の両端部を挿入し、前後縁に形成した溝に前壁17および後壁20の両端を挿入して機械的に抜止め結合しているが、接着により結合してもよい。
【0022】
製氷水タンク30は、図1および図2に示すように、正面から見て中央部の左側が下方に凹んだ略三角形状で上側が解放された箱形で、その左右両側に張り出した浅い支持部30aを前述した製氷部ケースBのタンク支持溝11に前側から挿入することにより着脱可能に支持されている。製氷水タンク30のもっとも深い部分は左ブラケット10L側に位置しており、この部分の前部には左ブラケット10L側に突出する給水口33が形成されている。また左ブラケット10L側の支持部30aに接近した浅い部分の底面には前後方向中間部(図6参照)にオーバフロー穴34が形成されている。製氷水タンク30の前部に形成した立上り壁30bは各セパレータ25の下縁に接近した位置まで上方に延ばされ、左右の側壁30cは立上り壁30bと同じ高さとなる前部を除きタンク支持溝11内に挿入可能な高さである(図6参照)。
【0023】
図1、図2および図6に示すように、左ブラケット10Lの下側には、前後方向中間部よりも後側でかつ製氷水タンク30の給水口33を設けた部分よりも左側に位置して、ドレンパン37が設けられている。このドレンパン37は左ブラケット10L下部の延長部16の下側に形成した突出部16a(図1参照)にねじ止め固定され、ドレンパン37の底部に設けた排出口38には排水パイプ39が接続されている。この排水パイプ39の先端は、貯氷庫72の底部に設けた排水口72aに導かれている。
【0024】
図1および図6に示すように、左ブラケット10Lの延長部16の下面にボルト止め固定された散水ポンプ45はドレンパン37の内側に位置しており、散水ポンプ45のポンプ部45aの吸入口45bはドレンパン37から前方に突出して吸入管46が連結され、吸入管46の他端は着脱が容易な管継ぎ手46aを介して製氷水タンク30の給水口33に接続されている。ポンプ部45aの吐出口45cに一端が連結された給水ホース47は左ブラケット10Lに形成した2枚の補強リブ14aの間および挿通穴15を通して製氷部ケースB内に入り、他端は次に述べる散水ノズル40に接続されている。製氷水タンク30のオーバフロー穴34は、ドレンパン37内の一部に上下方向に形成した仕切通路37aの上方に位置している。
【0025】
散水ノズル40は上下1対の合成樹脂成形品を全体として扁平形状となるように超音波溶着により液密に結合したもので、互いに連通される縦横の管状通路よりなり、その上面には24個の噴出口43が4行6列に形成されている。散水ノズル40の一側には横方向の各管状通路を掃除するための2つの開口が形成され、各開口はシリコンゴム製のキャップ42により液密に閉じられている。この散水ノズル40は、左右両端部が製氷部ケースBのノズル支持溝12内に前側から挿入されて取り付けられ、その中央部上側に形成した給水口には給水ホース47の他端が接続されている。
【0026】
製氷部ケースB内の上部に位置する製氷室50は、図2に示すように、両端が左右の各ブラケット10L,10Rの上部に支持された製氷基板51に、下側が開口された短くて丸い筒状の24個の製氷セル52を、散水ノズル40の各噴出口43と整列して固定したものである。各製氷セル52および製氷基板51は熱伝導性のよい銅またはアルミニウムのような金属製であり、製氷基板51の上側には各製氷セル52の中心を通るように冷却パイプ53が蛇行して密着固定され、この冷却パイプ53には機械室71内の冷凍機からの冷媒が循環供給されて製氷セル52を冷却するようになっている。
【0027】
アイスシュート60は、図1および図2に示すように、縦方向に並んだ多数の細長いスライド板71の前後端および中間部を連結材62a,62b,62cにより連結し、前後部の下面を各1対の横方向の支持脚片63により連結した簀の子状のもので、全体が合成樹脂により一体成形されている。このアイスシュート60は各1対の支持脚片63を2本のシュート支持筒24の外周面に弾性的に係合することにより、散水ノズル40のすぐ上側で前下がりに傾斜するように製氷部ケースB内に支持され、各スライド部材61の間の隙間は散水ノズル40の各噴出口43と整列され、各噴出口43から噴出される製氷水がアイスシュート60により邪魔されないようになっている。
【0028】
製氷運転に際しては、冷凍機を運転させて各製氷セル52を冷却し、オーバフロー穴34のレベルまで予め充満された製氷水タンク30内の製氷水を散水ポンプ45により吸入し、給水ホース47を介して散水ノズル40に供給して各噴出口43から各製氷セル52に向けて上方に噴出する。噴出された製氷水はアイスシュート60の各スライド部材61の間を通って冷却された各製氷セル52の内面に当てられて一部はその内面に氷結され、残りは重力により製氷水タンク30内に戻され、再び散水ポンプ45により散水ノズル40に供給され、繰り返して製氷セル52の内面に向けて噴出されるので、時間の経過につれて各製氷セル52内に氷結される氷は次第に多くなり、製氷水タンク30内の製氷水のレベルは次第に低下する。製氷セル52内が氷によりほゞ充満されたところで、製氷運転を停止して冷却パイプ53にホットガスを導入すれば、製氷室50は加熱されて各製氷セル52とその内部に生成された氷との境界部が溶解するので、各製氷セル52内の氷は短い円柱状の氷塊Cとなってアイスシュート60上に落下し、セパレータ25に向かって斜め前下方に滑り落ちる。そして重力により垂れ下がって閉じられているセパレータ25を自動的に押し開いて製氷部ケースB内から貯氷庫72内に落下される。
【0029】
そして供給ホース(図示省略)により所定量の製氷水を製氷水タンク30内に供給し、再び冷凍機を運転させ製氷室50を冷却して製氷運転を繰り返し行う。
製氷水を供給する際に製氷水タンク30内の製氷水のレベルがオーバフロー穴34よりも高くなれば、余分の製氷水はオーバフロー穴34からドレンパン37内に排出され、排水パイプ39を通って外部に排出される。また製氷運転中は、各セパレータ25は重力により垂れ下がって製氷部ケースBの開口Baは閉じられているので、製氷部ケースB内で飛び散る製氷水が貯氷庫72内に入ることはなく、従ってその中に蓄積された氷塊Cが溶解されたりたり、再氷結により氷塊Cどうしがくっついたり、あるいは製氷運転の途中で製氷水が不足したりすることはない。
【0030】
この実施の形態によれば、複数に分割された各セパレータ25は上部の係合部25bにより前壁17の下縁部の枢支ロッド18に離脱可能に係止されているので、各セパレータ25を容易に製氷部ケースBから取り外し、また取り付けることができる。従って製氷部ケースB内に設けた散水ノズル40またはアイスシュート60などの保守点検を容易に行うことができる。
【0031】
なお散水ノズル40またはアイスシュート60などの保守点検には、必ずしも全部のセパレータ25を取り外す必要はない。すなわち、1つのセパレータ25だけを取り外し、その他のセパレータ25は図9に示すように、扇状突起26が凹部19aから外れて各スリット19の間の前壁17が係合部25bの開放部25cの範囲に入る角度まで持ち上げ、取り外したセパレータ25側にその他のセパレータ25を横移動させ、係合部25bの先端部が前壁17に当接するようにして、セパレータ25が重力に抗してその角度に保持されるようにすればよい。
これにより各セパレータ25は大きく開いた状態に維持されるので、取り外さなくても散水ノズル40からの散水の状態やアイスシュート60その他の洗浄など、製氷機構部A内部の保守点検を行うことができる。
【0032】
この実施の形態では、セパレータ25は製氷基板51の製氷セル52の列数と同じ6個に分割されており、また各セパレータ25の係合部25bは丸棒状の枢支ロッド18により支持されてその揺動は軽いのでただ1個の氷塊Cでも確実に開き、アイスシュート60上に氷塊が残留することはなくなる。従って、製氷運転中に散水ノズル40から噴出される製氷水によりアイスシュート60上に残留した氷塊Cが溶けて無駄になったり、あるいは製氷水の噴出がこの氷塊Cにより邪魔されて製氷運転に支障が生じたりすることはない。
【0033】
また各セパレータ25の係合部25bの開放部25cの幅は丸棒状の枢支ロッド18の外径より小とし、各係合部25bを弾性的に変形させ開放部25cを一時的に開いて係合部25bの円弧状内面が枢支ロッド18の外周面に回動自在に係合されるようにしたので、各係合部25bが再び弾性変形する程度まで力を加えない限り、セパレータ25が枢支ロッド18から外れることはない。これにより枢支ロッド18に吊り下げ支持された各セパレータ25は枢支ロッド18から外れにくくなるので、各セパレータ25の作動の信頼性は高いものとなる。
【0034】
上述した実施の形態のような扇状突起26およびこれを挿通可能な凹部19aを設けなければ、図10および図11に示すセパレータ1のように、係合部1aを上述した実施の形態とは逆向きに、すなわち係合部1aの開放部2bが製氷部ケースBの内側に向くように取り付けることも可能である。そしてこの場合は、スライド部材61上を矢印E1のように滑る氷塊Cによりセパレータ1に加えられる矢印F1方向の衝撃力は、矢印E2に示すようにセパレータ1を開くように作用すると同時に、係合部1aには矢印F3で示すような衝撃力を及ぼす。この衝撃力F3は開放部2bを開いて係合部1aを枢支ロッド18から外すように作用するので、場合によってはスライド部材61を滑り落ちる氷塊Cにより枢支ロッド18からセパレータ1が外れるおそれがある。また、ときには誤って図11に示すようにセパレータ1を取り付けるおそれもあり、この場合はスライド部材61を滑り落ちる氷塊Cはセパレータ1の上に乗ってしまって開口Baから貯氷庫72内に落下されないので、セパレータ1を外して取り付け直さなければならなくなる。
【0035】
しかしながら上述した実施の形態では、各セパレータ25は、図4に示すように、必ず開放部25cが製氷部ケースBの外側に向く位置となるように枢支ロッド18に揺動自在に吊下げ支持され、図10および図11のようにこれと逆向きに前壁17に取り付けられることはない。この状態では、スライド部材61上を矢印E1のように滑る氷塊Cによりセパレータ25に加えられる矢印F1方向の衝撃力は、矢印E2に示すようにセパレータ25を開くように作用すると同時に、係合部25bには矢印F2で示すような衝撃力を及ぼす。この衝撃力F2はC形断面形状の係合部25bの開放部25cと反対側を枢支ロッド18に押し付けるように作用するので、このような力により開放部25cが開いてセパレータ25が枢支ロッド18から外れるおそれはない。従って各セパレータ25の作動の信頼性はいっそう高いものとなる。
【0036】
上述した実施の形態では、各セパレータ25の平板部25aの互いに隣接する側縁27の間の隙間は、図3および図5の実線に示すように、長手方向および厚さ方向の何れにおいても狭い一定幅としている。このようなセパレータ25では、各側縁27の間の隙間に入り込んだ製氷水の表面張力により隣接するセパレータ25どうしが互いに張り付き、個々のセパレータ25の動きが重くなるので、少数の氷塊がアイスシュート60上に残留するおそれが生じる。
【0037】
このような問題を解決するには、図3の二点鎖線に示すように、互いに隣り合う各セパレータ25の平板部25aの互いに隣接する側縁27の少なくとも一方に少数(図示の例では2個)の突部29a,29bを設け、これらの突部29a,29bを除く部分には一定幅Mの切欠き28a,28b,28cを設けて隣接する側縁27の間の隙間を増大させるようにすればよい。または図5の二点鎖線27aに示すように、互いに隣接する側縁27の少なくとも一方に面取りを設けて側縁27の先端の厚さを減少させればよい。あるいは互いに隣接する側縁27の少なくとも一方に少数の突部29a,29bを設けてその先端の厚さを減少させてもよい。
【0038】
平板部25aの側縁27に突部29a,29bを設けたものによれば、隣接する側縁27の間に表面張力により入り込む製氷水は突部29a,29bの部分だけとなり量が減少し、入り込んだ製氷水の表面張力による隣り合うセパレータ25どうしの張り付き力は減少するので、個々のセパレータ25の動きが過度に重くなることはなくなり、ただ1個の氷塊Cでも各セパレータ25は開くようになる。従って氷塊がアイスシュート60上に残留するおそれはなくなる。各突部29a,29bの長さN1,N2ならびに各切欠き28a,28b,28cの長さL1,L2,L3および幅Mは、表面張力による各セパレータ25どうしの張付き力と、切欠き28a,28b,28cを設けることによる製氷水の貯氷庫72への漏れの増大を考慮して定めればよい。
【0039】
また平板部25aの側縁27に面取り27aを設けて側縁27の先端の厚さを減少させたものによっても、隣接する側縁27の間に表面張力により入り込む製氷水の量は先端の厚さが減少した分だけ減少して表面張力による隣り合うセパレータ25どうしの張り付き力は減少するので、個々のセパレータ25の動きが過度に重くなることはなくなり、氷塊がアイスシュート60上に残留するおそれはなくなる。
【0040】
なお図3では、突部29a,29bおよび面取り27aは、互いに隣り合うセパレータ25の平板部25aの互いに隣接する側縁27のうちただ1組にだけ二点鎖線により記入したが、これらは互いに隣接する側縁27の全てに設けるものである。
【0041】
【発明の効果】
本発明によれば、複数に分割された各セパレータは上部が製氷部ケースに離脱可能に係止されているので、各セパレータを容易に製氷部ケースから取り外し、また取り付けることができる。従って散水ノズルまたはアイスシュートなどを設けた製氷部ケース内の保守点検を容易に行うことができる。
【0042】
前壁の下縁に丸棒状の枢支ロッドを一体的に連結するとともにスリットを形成し、複数の各セパレータは円弧状内面を有する係合部により揺動自在に吊下げ支持したものによれば、セパレータの係合部は丸棒状の枢支ロッドにより支持されるのでその揺動は軽くなり、複数に分割したことにより1個のセパレータの重量が軽くなることと相まって僅かの氷塊でも開いてアイスシュート上に氷塊が残留することはなくなる。
【0043】
また各係合部の円弧状内面両端の間の開放部の幅は丸棒状の枢支ロッドの外径より小とし、各係合部は弾性的に変形させて開放部の幅を拡大することにより枢支ロッドに回動自在に係合したものによれば、枢支ロッドに吊り下げ支持された各セパレータは枢支ロッドから外れにくくなるので、各セパレータの作動の信頼性は高いものとなる。
【0044】
また各係合部は、各セパレータが自然に吊り下げられた状態において開放部cが製氷部ケースの外側に向くように枢支ロッドに係合支持したものによれば、アイスシュート上を滑り落ちる氷塊がセパレータの内側に衝突したときの衝撃力は、C形断面形状の係合部の開放部と反対側を枢支ロッドに押し付けるように作用するので、このような衝撃力により開放部が開いてセパレータが枢支ロッドから外れるおそれはない。従って各セパレータの作動の信頼性はいっそう高いものとなる。
【0045】
また各セパレータには係合部の横幅方向で中心から外れた位置の外周面に扇状突起を形成し、係合部を挿入するスリットには扇状突起と対応する位置に同扇状突起が挿通可能な凹部を形成したものによれば、セパレータの係合部を誤って枢支ロッドに逆向きに係合させて開放部が製氷部ケースの内側に向くように枢支ロッドに係合支持させることはなくなるので、前項に記載の効果は常に確実に達成される。
【0046】
また互いに隣り合う各セパレータの各平板部の互いに隣接する側縁の少なくとも一方に少なくとも1個の突部を設けたものによれば、この突部を除く部分は隣接する平板部との間の隙間を増大するので互いに隣接する側縁の間に表面張力により入り込む製氷水の量は減少する。これにより入り込んだ製氷水の表面張力による隣り合うセパレータどうしの張り付き力は減少するので、個々のセパレータの動きが過度に重くなることはなくなり、氷塊がアイスシュート上に残留するおそれはなくなる。
【0047】
また互いに隣り合う各セパレータの各平板部の互いに隣接する側縁の少なくとも一方の先端の厚さを減少させたものによっても、互いに隣接する側縁の間に表面張力により入り込む製氷水の量は側縁の厚さが減少した分だけ減少する。従ってこのような製氷水の表面張力による隣り合うセパレータどうしの張り付き力は減少するので、個々のセパレータの動きが過度に重くなることはなくなり、氷塊がアイスシュート上に残留するおそれはなくなる。

BACKGROUND OF THE INVENTION
The present invention relates to an ice making mechanism of an automatic ice making machine, and more particularly to an improvement in a separator provided in an opening for feeding out ice blocks of the ice making case.
[0002]
[Prior art]
In this type of automatic ice making machine, as disclosed in, for example, Japanese Patent Application Laid-Open No. 60-89659, the ice making mechanism provided in the upper part of the ice making machine body 8 is cooled by the cooling pipe 5 during the ice making operation. The ice making cup 4 receives ice making water ejected from the sprinkler 16 below and freezes it. When the ice forming is completed, the ice making operation is stopped, and hot gas is supplied to the cooling pipe 5 to generate in the ice making cup 4. The formed ice block is dropped onto an inclined slope 13 and dropped into the lower ice storage 10 through the opening on the front side of the ice making mechanism. The opening on the front side of the ice making mechanism part is provided with a water shielding plate 21 made of a flexible sheet or the like that hangs down due to gravity, and the ice block that slides down the slope 13 pushes the water shielding plate 21 down and falls into the ice storage 10. The ice making water ejected from the water sprinkler 16 is not blocked by the water shielding plate 21 and enters the ice storage 10, so that ice blocks in the ice storage 10 are melted or ice making water during the ice making operation. There is no shortage.
[0003]
The water shielding plate 21 of the above prior art is made of a flexible sheet. However, in Japanese Patent Laid-Open No. 60-86876, an upper portion of a plurality of strip-shaped curtains 4 is supported by a support shaft 4a so as to be tiltable. It is disclosed as a water shielding plate.
[0004]
[Problems to be solved by the invention]
In the first prior art described above, the entire water shielding plate 21 is integrally formed. Therefore, if a small number of ice blocks remain on the slope 13, the water shielding plate 21 can be pushed open only by its weight. Instead, it remains on the slope and melts by the ice making water sprinkled from the water sprinkler 16 so that the ice is consumed wastefully or disturbs the sprinkling of the ice making water. The problem is that, as in the second prior art, the water shielding plate is divided into a plurality of curtains 4 and the upper portions of the water shielding plates are separately supported so that they can be tilted separately, and one ice block pushes only one curtain 4 open. This can be solved by dropping into the ice storage 10. However, this type of ice making mechanism is equipped with a water shielding plate (separator) provided at the opening on the front side of the ice making mechanism for the purpose of maintenance and inspection of a sprinkler (spray nozzle) and a slope (ice chute) provided inside. However, since it is not easy to remove the water shielding plate in each of the above-described conventional techniques, there is a problem that it takes time to perform maintenance and inspection inside the ice making mechanism.
[0005]
In order to solve such a problem, the present invention divides each separator into a plurality of parts and makes them detachable, lightens the operation so that each of the divided separators can be opened even by a small ice block, and further, an installation error of each separator. The purpose is to prevent problems caused by.

During the ice making operation, the ice making cells 52 are cooled by operating the refrigerator, and the ice making water in the ice making water tank 30 pre-filled up to the level of the overflow hole 34 is sucked by the sprinkling pump 45, and is passed through the water supply hose 47. Then, the water is supplied to the water spray nozzle 40 and ejected upward from each ejection port 43 toward each ice making cell 52. The ejected ice-making water is applied to the inner surface of each ice-making cell 52 cooled through the slide members 61 of the ice chute 60, and a part of the ice-making water is frozen on the inner surface, and the rest is in the ice-making water tank 30 by gravity. The water is again supplied to the water spray nozzle 40 by the water spray pump 45 and is repeatedly ejected toward the inner surface of the ice making cell 52, so that the amount of ice frozen in each ice making cell 52 gradually increases as time passes. The level of ice making water in the ice making water tank 30 gradually decreases. If the ice making operation is stopped and hot gas is introduced into the cooling pipe 53 when the inside of the ice making cell 52 is substantially filled with ice, the ice making chamber 50 is heated and the ice making cells 52 and the ice generated therein are generated. Therefore, the ice in each ice making cell 52 becomes a short columnar ice block C and falls onto the ice chute 60 and slides down diagonally forward and downward toward the separator 25. Then, the separator 25 that is hung down due to gravity and closed is automatically pushed open and dropped from the ice making unit case B into the ice storage 72.
[0029]
Then, a predetermined amount of ice making water is supplied into the ice making water tank 30 by a supply hose (not shown), the refrigerator is operated again, the ice making chamber 50 is cooled again, and the ice making operation is repeated.
If the ice making water level in the ice making water tank 30 becomes higher than the overflow hole 34 when supplying the ice making water, the extra ice making water is discharged from the overflow hole 34 into the drain pan 37 and passes through the drain pipe 39 to the outside. To be discharged. Further, during the ice making operation, each separator 25 hangs down due to gravity and the opening Ba of the ice making part case B is closed, so that ice making water splashing in the ice making part case B does not enter the ice storage 72, and therefore The ice blocks C accumulated therein are not melted, the ice blocks C stick together due to re-freezing, or the ice making water does not run short during the ice making operation.
[0030]
According to this embodiment, each of the divided separators 25 is releasably locked to the pivot rod 18 at the lower edge of the front wall 17 by the upper engaging portion 25b. Can be easily removed from the ice making case B and attached. Accordingly, maintenance and inspection of the watering nozzle 40 or the ice chute 60 provided in the ice making unit case B can be easily performed.
[0031]
It is not always necessary to remove all the separators 25 for maintenance and inspection of the watering nozzle 40 or the ice chute 60. That is, only one separator 25 is removed, and as shown in FIG. 9, in the other separator 25, the fan-shaped projections 26 are removed from the recesses 19a, and the front wall 17 between the slits 19 is the opening portion 25c of the engaging portion 25b. The separator 25 is lifted to an angle that falls within the range, and the other separator 25 is moved laterally to the removed separator 25 side so that the front end portion of the engaging portion 25b abuts against the front wall 17. It is only necessary to hold it.
As a result, each separator 25 is maintained in a largely open state, so that maintenance and inspection inside the ice making mechanism A can be performed, such as watering from the watering nozzle 40 and washing of the ice chute 60 and the like without being removed. .
[0032]
In this embodiment, the separator 25 is divided into six as many as the number of the ice-making cells 52 of the ice-making substrate 51, and the engaging portion 25b of each separator 25 is supported by a round rod-shaped pivot rod 18. Since the rocking is light, even a single ice block C opens reliably, and no ice block remains on the ice chute 60. Accordingly, ice blocks C remaining on the ice chute 60 are melted by the ice making water ejected from the water spray nozzle 40 during the ice making operation, and the ice mass C is obstructed by the ice blocks C, and the ice making operation is hindered. Will not occur.
[0033]
The width of the opening 25c of the engaging portion 25b of each separator 25 is smaller than the outer diameter of the round rod-shaped pivot rod 18, and each opening 25c is temporarily opened by elastically deforming each engaging portion 25b. Since the arc-shaped inner surface of the engaging portion 25b is rotatably engaged with the outer peripheral surface of the pivot rod 18, unless the force is applied to the extent that each engaging portion 25b is elastically deformed again, the separator 25 Does not come off the pivot rod 18. Thereby, each separator 25 suspended and supported by the pivot rod 18 is unlikely to be detached from the pivot rod 18, so that the operation reliability of each separator 25 is high.
[0034]
If the fan-shaped protrusion 26 and the recess 19a through which the fan-shaped protrusion 26 can be inserted are not provided as in the above-described embodiment, the engaging portion 1a is opposite to the above-described embodiment as in the separator 1 shown in FIGS. It is also possible to attach in the direction, that is, the open part 2b of the engaging part 1a faces the inside of the ice making part case B. In this case, the impact force in the direction of the arrow F1 applied to the separator 1 by the ice block C sliding on the slide member 61 as shown by the arrow E1 acts to open the separator 1 as shown by the arrow E2, and at the same time An impact force as shown by an arrow F3 is exerted on the portion 1a. This impact force F3 acts to open the opening 2b and disengage the engaging portion 1a from the pivot rod 18. In some cases, the separator 1 may be detached from the pivot rod 18 due to the ice block C sliding down the slide member 61. is there. In some cases, the separator 1 may be mistakenly attached as shown in FIG. 11. In this case, the ice block C sliding down the slide member 61 gets on the separator 1 and does not fall into the ice storage 72 from the opening Ba. The separator 1 must be removed and reattached.
[0035]
However, in the above-described embodiment, as shown in FIG. 4, each separator 25 is swingably supported by the pivot rod 18 so that the open portion 25 c is always positioned toward the outside of the ice making case B. 10 and 11, it is not attached to the front wall 17 in the opposite direction. In this state, the impact force in the direction of the arrow F1 applied to the separator 25 by the ice block C sliding on the slide member 61 as shown by the arrow E1 acts to open the separator 25 as shown by the arrow E2, and at the same time, the engaging portion An impact force as indicated by an arrow F2 is applied to 25b. Since this impact force F2 acts to press the opposite side of the opening 25c of the C-shaped cross-section engaging portion 25b against the pivot rod 18, the opening 25c is opened by such force and the separator 25 is pivotally supported. There is no risk of detachment from the rod 18. Accordingly, the reliability of the operation of each separator 25 is further increased.
[0036]
In the embodiment described above, the gap between the side edges 27 adjacent to each other of the flat plate portion 25a of each separator 25 is narrow in both the longitudinal direction and the thickness direction, as shown by the solid lines in FIGS. The width is constant. In such a separator 25, the adjacent separators 25 stick to each other due to the surface tension of the ice making water that has entered the gaps between the side edges 27, and the movement of the individual separators 25 becomes heavy. There is a risk of remaining on the surface 60.
[0037]
In order to solve such a problem, as indicated by a two-dot chain line in FIG. 3, a small number (two in the illustrated example) are provided on at least one of the side edges 27 adjacent to each other of the flat plate portions 25a of the separators 25 adjacent to each other. ) Protrusions 29a and 29b, and notches 28a, 28b and 28c having a constant width M are provided at portions excluding these protrusions 29a and 29b so as to increase the gap between the adjacent side edges 27. do it. Alternatively, as shown by a two-dot chain line 27a in FIG. 5, at least one of the side edges 27 adjacent to each other may be chamfered to reduce the thickness of the tip of the side edge 27. Alternatively, a small number of protrusions 29a and 29b may be provided on at least one of the side edges 27 adjacent to each other to reduce the thickness of the tip.
[0038]
According to the projections 29a and 29b provided on the side edges 27 of the flat plate portion 25a, the ice making water entering between the adjacent side edges 27 due to the surface tension becomes only the projections 29a and 29b, and the amount is reduced. The sticking force between the adjacent separators 25 due to the surface tension of the ice making water that has entered decreases, so that the movement of the individual separators 25 is not excessively heavy, and each separator 25 is opened even with only one ice block C. Become. Therefore, there is no possibility that ice blocks remain on the ice chute 60. The lengths N1, N2 of the protrusions 29a, 29b and the lengths L1, L2, L3 and the width M of the notches 28a, 28b, 28c are determined by the tension between the separators 25 due to surface tension and the notches 28a. 28b, 28c may be determined in consideration of an increase in leakage of ice-making water to the ice storage 72.
[0039]
Further, even if the chamfer 27a is provided on the side edge 27 of the flat plate portion 25a to reduce the thickness of the tip of the side edge 27, the amount of ice-making water entering between the adjacent side edges 27 due to surface tension is the thickness of the tip. Accordingly, the sticking force between the adjacent separators 25 due to the surface tension is reduced, so that the movement of the individual separators 25 is not excessively heavy, and ice blocks remain on the ice chute 60. It disappears.
[0040]
In FIG. 3, the protrusions 29 a and 29 b and the chamfer 27 a are indicated by a two-dot chain line in only one set of the side edges 27 adjacent to each other of the flat plate portion 25 a of the separator 25 adjacent to each other. It is provided on all of the side edges 27 to be performed.
[0041]
【The invention's effect】
According to the present invention, since the upper part of each of the divided separators is detachably locked to the ice making part case, each separator can be easily detached from and attached to the ice making part case. Therefore, maintenance and inspection in the ice making case provided with a watering nozzle or an ice chute can be easily performed.
[0042]
According to the invention, a round rod-shaped pivot rod is integrally connected to the lower edge of the front wall and a slit is formed, and each of the plurality of separators is suspended and supported by an engaging portion having an arcuate inner surface. Since the separator engaging portion is supported by a round rod-shaped pivot rod, its swinging is light, and by dividing into a plurality of pieces, the weight of one separator is lightened. No ice mass will remain on the chute.
[0043]
Also, the width of the open part between both ends of the arc-shaped inner surface of each engaging part should be smaller than the outer diameter of the round rod-shaped pivot rod, and each engaging part should be elastically deformed to expand the width of the open part. According to the embodiment, the separators that are pivotally engaged with the pivot rods are not easily detached from the pivot rods, so that the reliability of the operation of each separator is high. .
[0044]
In addition, according to the engaging portions that are supported by the pivot rod so that the opening portion c faces the outside of the ice making case when the separators are naturally suspended, the ice blocks sliding down on the ice chute Since the impact force when the cylinder collides with the inner side of the separator acts to press the opposite side of the C-shaped cross-section engaging portion against the pivot rod, the opening portion is opened by such an impact force. There is no risk that the separator will come off the pivot rod. Therefore, the reliability of the operation of each separator is further increased.
[0045]
Each separator is formed with a fan-shaped protrusion on the outer peripheral surface at a position off the center in the width direction of the engaging portion, and the fan-shaped protrusion can be inserted into a slit for inserting the engaging portion at a position corresponding to the fan-shaped protrusion. According to the one formed with the recess, the engaging portion of the separator is erroneously engaged with the pivot rod in the opposite direction, and the pivot rod is engaged and supported so that the opening portion faces the inside of the ice making unit case. Therefore, the effect described in the previous section is always achieved with certainty.
[0046]
Further, according to the structure in which at least one protrusion is provided on at least one of the side edges adjacent to each other of the flat plate portions of the separators adjacent to each other, the portion excluding the protrusion is a gap between the adjacent flat plate portions. Therefore, the amount of ice-making water that enters between adjacent side edges due to surface tension decreases. As a result, the sticking force between the adjacent separators due to the surface tension of the ice-making water that has entered decreases, so that the movement of the individual separators does not become excessively heavy, and there is no possibility that ice blocks remain on the ice chute.
[0047]
In addition, even if the thickness of at least one of the side edges adjacent to each other of the flat plate portions of the separators adjacent to each other is reduced, the amount of ice-making water that enters between the side edges adjacent to each other due to surface tension is reduced. Decreases by the decrease in edge thickness. Accordingly, the sticking force between the adjacent separators due to the surface tension of the ice-making water is reduced, so that the movement of the individual separators is not excessively heavy, and there is no possibility that ice blocks remain on the ice chute.
