Description

【０００１】
【発明の属する技術分野】
本発明は、冷蔵ショーケース等の冷却貯蔵庫に関する。
【０００２】
【従来の技術】
ビール等の冷飲料を冷却保存して販売等に供する冷蔵ショーケースの一般的な構造は、以下のようである。すなわち、前面開口の断熱箱体からなるケース本体を備え、その底部側に冷却器や冷却ファンの収容された冷却器室が設けられて、その上方に棚網等が装備される貯蔵室が形成され、前面開口に引き違い式のガラス扉が装着されている。一方、ケース本体の下面側には機械室が設けられ、圧縮機、凝縮器等からなる冷凍装置が収容されて、上記の冷却器と冷媒配管で接続されることにより冷凍サイクルが構成される。そして、冷凍装置と冷却ファンとが駆動されると、庫内空気が前面側から冷却器室に吸引され、冷却器を通過する間に熱交換されて生成された冷気が貯蔵室の奥面側に吹き出されるように循環流通し、貯蔵室内が冷却されるようになっている。
【０００３】
【発明が解決しようとする課題】
ところでこの種の業務用の冷蔵ショーケースでは、営業時間外等を見計らって自動的に除霜運転が行われるようになっていて、除霜水は装備されたドレンパンで受けられる。この除霜水は、自然蒸発に委ねたり、一部では所定時間ヒータに通電して強制蒸発処理されるが、特に多湿の雰囲気にある場所や時期にあっては蒸発し切れないで残る場合があるため、小まめにドレンパンを引き出して排水することが望ましい。
一方、冷凍装置については、凝縮器で冷媒を凝縮させるために、ファンで外気を引いてこれを当てることにより凝縮器を冷却するようにしている。このとき、外気中の塵等の侵入を防ぐために吸入側にはそれらの塵等を捕集するエアフィルタを配しているが、これについても目詰まりを起こす前に小まめに洗浄することが望ましい。
【０００４】
しかるに従来では、ドレンパンとエアフィルタとが個別に装着されていたため、日々のメンテナンスの際にこれらを取り付けたり取り外したりする作業を別々に行わねばならず、面倒であるという問題があった。
本発明は上記のような事情に基づいて完成されたものであって、その目的は、日常の清掃等のメンテナンスを簡単に行える機能を備えた冷却貯蔵庫を提供するところにある。
【０００５】
【課題を解決するための手段】
上記の目的を達成するための手段として、請求項１の発明は、貯蔵庫本体内を冷却する冷却器とともに冷凍サイクルを構成する圧縮機、凝縮器等からなる冷凍装置が収容された機械室を設けた冷却貯蔵庫において、前記機械室の底部にはドレンパンが出し入れ可能に装着され、このドレンパンには、前記冷却器からの除霜水等を受ける浅皿部と、前記凝縮器を冷却するためにファンにより吸入された空気中の塵等を捕集するエアフィルタが着脱可能に嵌め込まれるフィルタ装着部とが左右に隣接して設けられており、かつ前記フィルタ装着部の奥側の一部が、前記浅皿部の奥側の周壁よりも奥方に突出して形成され、このフィルタ装着部における奥方に突出した部分には、前記エアフィルタに突設された摘みを嵌めて逃がす逃がし溝が形成されている構成としたところに特徴を有する。
【０００６】
請求項２の発明は、請求項１に記載のものにおいて、前記ドレンパンの手前側の端縁には、前記機械室の底部の全幅にわたる長さを持った前壁部が一体的に設けられているところに特徴を有する。
請求項３の発明は、請求項２に記載のものにおいて、前記前壁部が、前記浅皿部と連通した樋部であるところに特徴を有する。
請求項４の発明は、請求項１ないし請求項３のいずれかに記載のものにおいて、前記エアフィルタが前記ドレンパンにおける上位位置に配設され、このエアフィルタの下面側並びに下側周面の一部が空気の吸入用に開放されているところに特徴を有する。
【０００７】
【発明の作用及び効果】
＜請求項１の発明＞
ドレンパンとエアフィルタとを同時に出し入れできるから、ドレンパンの排水とエアフィルタの洗浄とを能率良く行うことができ、日常のメンテナンスが楽になる。ドレンパンの排水とエアフィルタの洗浄とのいずれか一方の作業を行った際に、他方の作業が併せて喚起され、メンテナンスのし忘れが防止される。また部品点数が減少できるから、コストの低減を図ることができる。
また、エアフィルタがドレンパンに対して着脱可能となっているから、いずれか一方が損傷した場合に、損傷した方のみを交換すれば足りる。
＜請求項２，３の発明＞
ドレンパンの手前側の端縁には、機械室の底部の全幅にわたる長さを持った樋部が一体的に設けられ、この樋部が前壁部を兼用する。
【０００８】
＜請求項４の発明＞
エアフィルタをドレンパンの上位位置に設けて、エアフィルタの下面側に加えて、下側周面の一部を開放したから、空気の吸入面積を大きく確保することができる。
【０００９】
【発明の実施の形態】
以下、本発明の一実施形態を図１ないし図９に基づいて説明する。
この実施形態の冷蔵ショーケースは、図１及び図２に示すように、ケース本体１０の下面側に機械室１１が設けられ、機械室１１の底面に装備された脚１２、キャスタ１３によって支持されている。
ケース本体１０は、前面の開口された縦長の断熱箱体により形成されていて、その底部側には冷却器室１５が区画形成され、その中に冷却器１６と冷却ファン１７とが収容されている。冷却器室１５の上方は貯蔵室１８となっていて、棚網１９が装着されてビール等の冷飲料缶等が貯蔵されるようになっている。また、ケース本体１０の前面開口には、ガラス扉２０が引き違い形式で装着されている。
【００１０】
機械室１１内には、圧縮機２２、凝縮器２３等からなる冷凍装置２１が装備され、上記した冷却器１６と冷媒配管により接続されて周知の冷凍サイクルが構成されている。したがって、冷凍装置２１と冷却ファン１７とが駆動されると、庫内空気が冷却器室１５の天井面の手前側に形成された吸込口２５から吸引されて、冷却器１６を通過する間に熱交換されて冷気が生成され、この冷気が冷却器室１５の天井面の奥側に形成された吹出口２６から貯蔵室１８の奥面に沿って吹き出されるといった循環流が生じ、貯蔵室１８内が所定の冷却温度に保持されるようになっている。
【００１１】
上記した冷凍装置２１はユニット化されており、大まかには図４及び図５に示すように、機械室１１の底面を構成する基板２８の左奥側に圧縮機２２が設置されているとともに、右手前側に凝縮器２３が設置されている。凝縮器２３は、基板２８から所定寸法上方に浮いた状態で取り付けられており、下面と右側面が開放された凝縮器２３のケーシング２９内に収められている。ケーシング２９の右側面はケース本体１０の右側板で閉鎖され、結局はケーシング２９は下面のみが開放されている。ケーシング２９の配設位置の下方の基板２８上には、前後２個の窓孔３０が開口されている。また、ケーシング２９の左側面には、前後一対の凝縮器ファン３１が装備されている。
【００１２】
上記の機械室１１の底部側には、圧縮機２２の設置位置の手前側の領域から、凝縮器２３の設置位置の下面にわたって、ドレンパン３３が出し入れ可能に装着されている（図４の太い二点鎖線参照）。
ドレンパン３３は合成樹脂材によって成形されており、図６に示すように、機械室１１の全幅にわたる長さ寸法を持った樋部３４を有しており、樋部３４の奥側における左端から所定寸法入った位置から、長さ方向の中心を所定寸法超えた位置にわたって、横長の矩形状をなす浅皿部３５が底面を樋部３４と面一にして形成されている。樋部３４の長さ方向の中心には、手を差し入れることが可能な取手部３６が形成されている。なお、樋部３４の前壁における左右両端から少し入った位置の間と、取手部３６は一段背が高く形成されている。
【００１３】
上記のドレンパン３３における浅皿部３５の右隣には、エアフィルタ４１の装着部３８が形成されている。この装着部３８は、前後２個の枠部３９を連ねたような形状であって、浅皿部３５の上面と面一に形成されており、図４に示すように、凝縮器２３の下面から少し右側にわたる領域、言い換えると、上記した基板２８の窓孔３０の形成位置の上方に配設されるようになっている。この装着部３８の上面側にエアフィルタ４１が装着されるようになっている。そのため、装着部３８の上面側の内周縁には、嵌合凹部４２が段付き状に形成されている。
【００１４】
エアフィルタ４１は同じく合成樹脂製であって、方形の枠体４４を２つ連ねたような形状に形成され、上記した装着部３８の嵌合凹部４２内に嵌め込み可能となっている。各枠体４４内には、メッシュからなるフィルタ板４５が張られている。エアフィルタ４１の手前側と奥側の縁部からは、先端に鈎部４８を備えた弾性係止片４７が垂設されているとともに、装着部３８の手前側と奥側の縁部には、上記した弾性係止片４７を弾性的に係止可能な係止溝４９が形成されている。また、エアフィルタ４１の左奥の側縁からは摘み５１が張り出し形成されているとともに、装着部３８の対応位置には、摘み５１を嵌めて逃がす逃がし溝５２が形成されている。
また、ドレンパン３３における装着部３８の右側面には開口５４が形成されているとともに、前後の枠部３９の連設位置の下面からは、仕切板５５が垂設されている。
【００１５】
上記したドレンパン３３は、機械室１１の前面の底部に設けられた出入口５７から機械室１１の底面に沿って出し入れされ、取手部３６がストッパに当たる等で、樋部３４の前面が機械室１１の前面と面一となったところで押し込みが停止されるようになっている。
また、冷却器室１５の底面の手前側の位置には、図２に示すように除霜水の排水口５８が形成され、そこに接続されたドレンホース５９が、機械室１１内における圧縮機２２の設置位置の手前側に垂下されるようになっている。
【００１６】
続いて本実施形態の作用を説明する。
ドレンパン３３の装着部３８にエアフィルタ４１が装着され、このドレンパン３３が出入口５７から機械室１１の底部に挿入される。正規位置まで挿入されると、ドレンパン３３の浅皿部３５は圧縮機２２の手前側に位置し、その上方にドレンホース５９の下端が臨んだ状態とされる。一方のエアフィルタ４１は、凝縮器２３のほぼ下面側に対応して配される。
【００１７】
冷凍装置２１が駆動される際、それに伴って凝縮器ファン３１が駆動されると、主に機械室１１の右側面の下の隙間から窓孔３０を通って外気が吸引され、ドレンパン３３の装着部３８の下面側並びに右側面を通ってその上方に配されたエアフィルタ４１を流通する。このとき仕切板５５によって前後のフィルタ板４５に外気が振り分けられる。外気がエアフィルタ４１を通過すると、その中に混じった塵等が捕集されつつ、凝縮器２３を下面から左側面、あるいは右側面から左側面に通過し、これにより凝縮器２３が冷却される。冷却に供された後の暖気は、機械室１１の前面や後面、あるいは圧縮機２２の設置位置の底面に形成された排気口６０から外部に排出される。
【００１８】
ドレンパン３３に溜まった除霜水を廃棄する場合は、図８に示すように、取手部３６に手を入れてドレンパン３３を出入口５７から水平に引き出し、ドレンパン３３を傾けて除霜水を樋部３４に溜めつつその一端側からバケツや所定の水廃棄箇所に排水する。
エアフィルタ４１を洗浄する場合は、図９に示すように、ドレンパン３３の装着部３８からエアフィルタ４１を外す。詳細には、装着部３８の裏側に手を回して弾性係止片４７を係止溝４９から外し、摘み５１を摘んで起こすことで外すことができる。エアフィルタ４１を外したら、所定の水場で水洗いする。このとき、ドレンパン３３に水垢や汚れがあったら、併せて水洗いすればよい。
除霜水の排水とエアフィルタ４１の水洗いが完了したら、ドレンパン３３の装着部３８にエアフィルタ４１を装着した後、ドレンパン３３を出入口５７から機械室１１の底部に挿入する。
【００１９】
以上説明したように本実施形態によれば、エアフィルタ４１がドレンパン３３に対して着脱可能に装着された構造となっていて、ドレンパン３３とエアフィルタ４１とが同時に出し入れできるから、ドレンパン３３の排水とエアフィルタ４１の洗浄とを能率良く行うことができ、すなわち日常のメンテナンスが楽になる。ドレンパン３３の排水とエアフィルタ４１の洗浄とのいずれか一方の作業を行った際に、他方の作業が併せて喚起され、メンテナンスのし忘れが防止される。また部品点数が減少できるから、コストの低減を図ることができる。さらに、エアフィルタ４１とドレンパン３３とのいずれか一方が損傷した場合に、損傷した方のみを交換すれば足りる。
【００２０】
エアフィルタ４１がドレンパン３３の上面位置に設けられ、エアフィルタ４１の下面側に加えて、下側の右側面が開放された構造となっているから、外気の吸入面積を大きく確保することができる。
また、吸引された空気は仕切板５５によって前後の領域に振り分けられ、凝縮器２３の全域にわたって外気が満遍なく当てられて一様に冷却されるために、凝縮効率が向上される。
【００２１】
＜他の実施形態＞
本発明は上記記述及び図面によって説明した実施形態に限定されるものではなく、例えば次のような実施形態も本発明の技術的範囲に含まれ、さらに、下記以外にも要旨を逸脱しない範囲内で種々変更して実施することができる。
（１）本発明は冷蔵ショーケースに限らず、除霜水を受けるドレンパンと凝縮器に当てる空気から塵等を捕集するエアフィルタとを備えた冷却貯蔵庫全般に広く適用することができる。
