Description

【０００１】
【発明の属する技術分野】
この発明は、冷凍庫内等を冷却する冷凍装置の構成部品搭載構造に関するものである。
【０００２】
【従来の技術】
図１１は一般汎用の冷凍装置のシステムを説明するための概略図である。図に示した冷凍装置は、圧縮機およびその圧縮機に付帯する部品を備えた圧縮ユニット２１と、凝縮器や送風ファンを備えた放熱ユニット２２と、冷凍庫内を冷却するための蒸発器や送風ファンを備えた冷却ユニット２３とから主に構成されている。これらの各ユニットはそれぞれ個別に別置きされるが、冷凍サイクルを成すために冷媒配管を介して配管接続されている。すなわち、圧縮ユニット２１は屋内機械室等に配備され、冷却ユニット２３は被冷却物を冷却するための冷凍庫に配備され、凝縮ユニット２２は屋外に配備されている。このような方式はリモート式と呼ばれている。
また、図１２に示すように、圧縮ユニット２１と放熱ユニット２２が一体化された一体空冷ユニット２４もよく用いられ、放熱器の排熱のため屋外置きが一般的である。
【０００３】
図１３は下記の特許文献１に記載された構造であり、従来の圧縮ユニット２１（図１１）（もしくは一体空冷ユニット２４（図１２））を載置する台盤５２と、この台盤５２を支持する足部材とを主に示している。図１３において、符号１は冷凍サイクルの構成部品である圧縮ユニット２１等の本体ケーシングを示し、符号５２は本体ケーシング１の底壁面を構成する金属製の台盤を示している。台盤５２上には圧縮ユニット２１等の冷凍サイクルを構成する冷媒圧縮機等の部品と、それに付帯する制御機器等の部品が搭載されている。尚、これらの構成部品は本体ケーシング１に覆われているので示していない。

【０００５】
ところで、空気調和機やスーパーマーケット等のショーケースを冷却するための圧縮ユニット２１では、搬送時に台盤５２を支持する部材として腰下２５が用いられる。この腰下２５は木材で形成されていて、側面にフォークリフト等の爪を挿入させるための孔２６が形成されている。この腰下２５で台盤５２を支持することにより、孔２６にフォークリフト等の爪を挿入して搬送することができ、圧縮ユニット２１の搬送が容易となる。また、腰下２５には圧縮ユニット２１等を搬送する時に台盤５２が地面に直に接触して損傷するのを防ぐ役割もある。
【０００６】
また、図１４のように、フォークリフト等の爪を通すことができるよう、孔２６を有するアングル部材２７を組み合わせて台盤５２の外周縁部を下方から支持するように台盤５２の下に設置し、前記した腰下と同様の役割をもたせて搬送を容易にできるようにしているものもある。この場合、製品輸送、搬送時のみ使用されて廃材となる腰下を無くしたり、あるいは減らすことが可能となり、環境保全に関しても有用である。
【０００７】
また、本出願人が出願した特願２００２−１３５１９７号では、台盤の下面に、金属板材を折り曲げて形成された複数の足部材を互いにほぼ平行に取り付け、これらの足部材により台盤を支持するようにしたものがある。かかる構造では、足部材の体積、高さ、および質量を低減することが可能になり、足部材の材料コストおよび加工コストの低減、梱包高さおよび梱包質量の低減、並びにそれに伴う搬送コストの低減および据付性の改善を図ろうとしている。
【０００８】
また、前記の段落番号０００７で示した構造の他に、図１５のように、フォークリフト爪挿通用の孔２６を有するアングル部材２７を組み合わせて台盤５２の下方に設置し、その前後のアングル部材２７，２７の孔２６，２６における上左右縁の部分に橋渡し部材２８を架け渡した構造も一般的である。
【０００９】
また、前記の段落番号０００７で説明した足部材は台盤に脱着可能となっている。これにより、据付現場の水はけが悪い等、ユニットの高さを高くすることが望ましい場合には台盤に足部材をとりつけたままで据付け、不要であれば台盤から足部材を取り外して据付けるといったように、据付現場の状況に合わせて選択させることができて、据付性をさらに向上させるようにしている。
【００１０】
従来、箱型形状の圧縮ユニットや空気調和機の他ユニットへの配管接続は、図１６のように本体ケーシング１に配管接続用の孔２９を形成し、これらの孔２９を通して行われてきた。この場合、本体ケーシング１には、例えば前面パネルや右面パネルに予め孔形状の切り込みを入れるなどして、使用者が接続用の孔２９を設けることが容易になるような構造となっている。
【００１１】
また、一体空冷式（図１２）の場合は接続する配管が２本と少ないため、前記のようにアングル部材を組み合わせて台盤の下にフォークリフト爪の差込用空間を形成した構造では、図１７の如く、アングル部材２７の水平面部に配管接続用孔３３（切欠き）を設けることで、配管８を下方向やアングル部材２７外に取り出し、その後ユニットの前後左右下方向に配管施工できるようにしてある。
【００１２】
【発明が解決しようとする課題】
従来の装置は以上のように構成されており、アングル部材２７を組み合わせて台盤５２の下に空間を形成した構造の場合、断面図は図１８のとおりとなる。この構造では、倉庫での保管時やトラックでのユニットの輸送中等の際に、他のユニット３１と隣接して設置された場合、フォークリフトの爪３０をユニット奥側のアングル部材からはみ出して搬送すると、爪３０の先端で隣接ユニット３１を傷つける可能性が高くなる。逆に、隣接ユニット３１を傷つけないよう爪３０がほとんどはみ出さないようにして搬送すると、爪３０の先端がユニット奥側のアングル部材から外れて台盤５２の裏面に接触し台盤５２を傷つけたり、さらには圧縮ユニット２１が転倒する場合もある。
【００１３】
一方、図１９のとおり、前側アングル部材と奥側アングル部材の距離を短くすることにより水平部３２の長さを長く採るように構成すれば、爪３０が奥側アングル部材の垂直部からある程度はみだしても本体ケーシング１からははみ出すことがなく、すなわち隣接して置かれているユニット３１を傷つけることもない。また、この構造の場合、接続配管が４本と多いリモート式の圧縮ユニット２１の場合も配管を台盤５２の下から取り出し、本体ケーシング１の前後左右下方向に施工することができる。
【００１４】
ただし、この構造の場合、アングル部材の下側の水平部３２が落下強度に対して弱いため、補強が必要となる。また、上側の水平部３２も圧縮機等重量の重い部材を支える必要があるので、補強が必要となる。また、爪３０を挿入した場合、前側アングル部材と奥側アングル部材の垂直部間の距離が短いため、搬送時にユニット２１（または２４）が不安定となる。
【００１５】
あるいは、図１５のように、前後のアングル部材２７，２７の孔２６，２６の上左右縁の部分に橋渡し部材２８を架け渡せば、フォークリフトの爪を橋渡し部材２８の途中まで挿入して隣接ユニットを傷つけずにユニットの搬送が可能となる。この場合、配管を台盤５２下から取り出し、ユニット２１，２４の前後左右下方向に施工するためには、四角に囲まれているアングル部材２７，２７，２７，２７の内側部に配管を取り出せるよう、台盤５２やアングル部材２７に孔をあけることが必要となる。
【００１６】
しかし、図２０のように、幅が狭いユニット構造の場合、台盤５２の下から配管を取り出し、ユニットの前後左右下方向に施工可能な構造とするために、四角に囲まれているアングル部材２７，２７，２７，２７の内側部に配管を取り出せるよう台盤５２やアングル部材２７に孔２９等をあけたとしても、橋渡し部材２８が干渉して施工不可となる。この場合、配管施工時に、図１６のように配管を本体ケーシング１の外周に取り回すことが必要となる場合があり、その場合は施工配管長さが長くなって経済性も悪くなる。また、配管を取り回すスペースが必要となり、冷凍装置の設置に必要な面積も大きくなる。
【００１７】
この発明は上記のような問題点を解消するためになされたもので、冷凍装置を構成するユニットが他のユニットに隣接しておかれた場合でも安全で安定した搬送が可能であること、台盤等の強度を確保しながら配管施工時に配管を台盤下から取り出し、ユニットの前後左右下方向へ自在に施工可能とすることにより配管施工の自在性、経済性の確保、または、ユニット搬送後に生じる木材等の廃材削減化を図ることのできる冷凍装置の提供を目的とする。
【００１８】

【００２３】
【発明の実施の形態】
発明の実施の形態１．
以下、本発明の実施の形態を図面に基づいて説明する。図１はこの発明の実施の形態１による台盤を示す斜視図、図２はこの発明の実施の形態１による台盤の側断面図である。
各図において、この実施形態の冷凍装置は、冷凍サイクルの圧縮ユニットを構成する部品（例えば、圧縮機やオイルセパレータ等）およびこれらの部品に付帯する部品（例えば、制御用の電機部品等）を、例えば板金製の台盤２上に搭載している。尚、これらの各部品は台盤２の上に設置・固定されているが、ここでは図示を省略し、圧縮ユニット２１の本体ケーシング１（図４参照）だけを図示する。かかる台盤２は、本体ケーシング１で囲まれた圧縮ユニット２１の構成部品を載置する平面視ほぼ四角形状の上板部４１と、上板部４１の前辺に垂下して設けられた前板部４２と、上板部４１の後辺に垂下して設けられた後板部４３と、上板部４１の右辺に垂下して設けられた側板部４４と、上板部４１の左辺に垂下して設けられた側板部４５とを備えており、底面全体が開口している。これにより、台盤２は、上板部４１の下方で、前板部４２、後板部４３、側板部４４、および側板部４５の間に、空間部４６を有している。
【００２４】
上板部４１には配管取り出し用の上板貫通孔５が複数形成され、前板部４２にはフォークリフト爪挿通用および配管取り出し用の前板貫通孔３ａ，３ｃが横並びに形成されている。これらの前板貫通孔３ａ，３ｃと対向する位置の後板部４３には、フォークリフト爪挿通用および配管取り出し用の後板貫通孔３ｂ，３ｄがそれぞれ形成されている。この場合、フォークリフトの２つある爪のうち、片方の爪が孔３ａと３ｂに挿通され、もう一方の爪が孔３ｃと３ｄに挿通される。そして、側板部４４にはフォークリフト爪挿通用および配管取り出し用の側板貫通孔４ａ，４ｂが横並びに形成されている。これらの側板貫通孔４ａ，４ｂと対向する位置の側板部４５にも、フォークリフト爪挿通用および配管取り出し用の側板貫通孔４ｃ，４ｄがそれぞれ形成されている。これらの孔３ａ，３ｂ，３ｃ，３ｄや孔４ａ，４ｂ，４ｃ，４ｄは製品搬入後に冷却器、放熱器への配管を通すための孔としても使用される。
【００２５】
そして、板金で側面視凹字状に形成された第１補助板部材６のひとつが前板貫通孔３ａと後板貫通孔３ｂの間に架け渡され、もうひとつの第１補助板部材６が前板貫通孔３ｃと後板貫通孔３ｄの間に架け渡されている。これらの第１補助板部材６，６は一端が前板貫通孔３ａ，３ｃの上縁１５ａ，１５ａにあてがわれた状態で前板部４２にネジ７（固定手段の例）により脱着可能に取り付けられている。第１補助板部材６，６の他端は後板貫通孔３ｂ，３ｄの上縁１５ｂ，１５ｂにあてがわれた状態で後板部４３にネジ７（固定手段の例）により脱着可能に取り付けられている。
尚、台盤２の構造としては、図１のように腰下の機能を兼ねた箱型のものに限らず、従来技術で説明したようなフォークリフト等の爪を通すことのできる孔２６を有するアングル部材２７（図１４，１５，１７，１８，２０）を組み合わせて台盤の外周縁部を下方から支持するように設置した構造でもよい。
【００２６】
上記のように、台盤２に第１補助板部材６を設けた構造としたことで、図３の如く、フォークリフトの爪３０を背面の後板貫通孔３ｂ，３ｄ（図示せず）からはみ出させることなくユニットの持ち上げ搬送が可能となる。これにより、ユニットが他のユニットに隣接しておかれている場合でも隣接ユニットを傷つけることはない。また、フォークリフトの爪３０が背面側の後板貫通孔３ｂ，３ｄに届かなくてもよいので、これらの後板貫通孔３ｂ，３ｄから爪３０が外れて台盤２の裏と接触し台盤２を傷つけるといったことがなく、さらにはユニット転倒を引き起こすこともなく、安全で安定した搬送が可能となる。
【００２７】
一方、第１補助板部材６はネジ７等で取り外し可能に固定されているので、製品搬入後はネジ７を外して第１補助板部材６を取り外すことで、接続配管が４本と多いリモート式の圧縮ユニット２１の場合でも、台盤等の強度を確保しながら、図４のとおり、配管８（８ａ，８ｂ，８ｃ）を台盤２から取り出して、圧縮ユニット２１の前後左右下方向に配管施工をすることができる。図は分かりやすくするため、左側の配管経路８ａ、前側の配管経路８ｂ、および下側の配管経路８ｃのみを示し、後側、右側は省略しているが、これらの側でも配管施工は可能である。また、台盤２の背面の後板貫通孔３ｂ，３ｄ、側面の側板貫通孔４ｃ，４ｄも省略しているが、これらの側でも配管施工は可能である。
このように、配管８を台盤２下の空間部４６から取り出し、圧縮ユニット２１の前後左右下方向に施工可能にすることで、配管施工の自在性を確保でき、配管施工がユニット外周を取りまわしすることなく最短で可能となる。従って、配管施工の経済性も向上し、また配管をとりまわすスペースも少なくできるため、冷凍装置の設置に必要な面積も小さくできる。
【００２８】
尚、台盤２の側板貫通孔４ａ〜４ｄは配管を通すための孔であると説明したが、フォークリフトの爪を通せる大きさに形成しておけば、側面から爪を差込み搬送可能なユニットとすることができ、前記の段落番号００２７で説明したことと同様の効果が得られる。
【００２９】
また、台盤２は腰下機能も兼ねているので、ユニット搬送後に生じる木材等の廃材を削減することができる。
【００３０】
尚、この実施の形態１では第１補助板部材６を固定する手段としてネジ７を例示したが、第１補助板部材６を脱着可能に固定する手段であればどのようなものでもよく、ネジ７以外の種々の固定手段、例えばフックと係止穴の組み合わせ、ボルトとナットの組み合わせ、その他の構造を採用することが考えられる。
【００３１】
また、この実施の形態１では第１補助板部材６として側面視凹字形状のものを採用したが、台盤２の孔３ａと３ｂの間、孔３ｃと３ｄの間に橋渡しでき、ネジ等で脱着可能に固定されるものであればどのような構造でもよく、凹字形状以外の形状を採用することも考えられる。また、台盤２の孔４ａと４ｃの間、孔４ｂと４ｄの間を橋渡しする補助板部材を採用した場合も同様の効果が得られる。
【００３２】
発明の実施の形態２．
図５は本発明の実施の形態２に係る台盤を示す斜視図である。図に示した台盤２ａは、前記の第１補助板部材６に替えて第２補助板部材９を用いたこと以外、実施の形態１の台盤２と同様の構成である。従って、共通する構成要素には前記の図１、図２、図３、図４と同じ符号を付して重複する説明を省略する。また、台盤２ａが圧縮ユニット２１の本体ケーシング１の底面部を構成する態様も同様であるので説明を省略する。
【００３３】
前記の第２補助板部材９，９は例えば板金で側面視Ｌ字状に形成されていて、それぞれの一端側が前板貫通孔３ａ，３ｃの上縁１５ａ，１５ａにあてがわれた状態で、一端がネジ７（固定手段の例）により前板部４２に脱着可能に取り付けられている。因みに、第２補助板部材９は、圧縮ユニット２１の重心１０の位置に応じて、たとえば圧縮ユニット２１の重心１０がユニット前面側の位置にあれば、図６のように、第２補助板部材９が台盤２ａの前板貫通孔３ａ，３ｃに設置される。ここで、図６の第２補助板部材９の地面１８に平行の面の長さは本体ケーシング１の前面から重心１０までの距離Ａよりも長ければよい。すなわち、第２補助板部材９の他端４７は後板貫通孔３ｂ，３ｄに向かって延在し、台盤２に搭載される圧縮ユニット２１の重心１０から地面１８に向けて垂直に下ろした点１１を結ぶ線１２を超えて配置されている。このようにすれば、ユニット前面から台盤２ａの前板貫通孔３ａ，３ｃにフォークリフトの爪を挿入した場合、あるいはユニット後面から台盤２ａの後板貫通孔３ｂ，３ｄに爪を挿入した場合でも、フォークリフトの爪を線１２を超えて奥まで挿入すれば、圧縮ユニット２１の安定した、安全な搬送が可能となる。
【００３４】
尚、前記の第２補助板部材９は、一端を後板部４３にネジ７（固定手段の例）により脱着可能に取り付け、一端側を後板貫通孔３ｂ，３ｄの上縁１５ｂ，１５ｂにあてがい他端４７を前板貫通孔３ａ，３ｃに向けて延在させてもよい。
【００３５】
他方で、圧縮ユニット２１の重心１０がユニット後面側の位置にある場合、第２補助板部材９は一端が台盤２ａの後板貫通孔３ｂ，３ｄに設置され他端４７が前板貫通孔３ａ，３ｃに向かって延在される。この場合も、第２補助板部材９の地面１８に平行の面の長さは圧縮ユニット２１の後面から重心１０までの距離よりも長ければよい。これにより、前記と同様、ユニット前面から台盤２ａの前板貫通孔３ａ，３ｃにフォークリフトの爪を挿入した場合、あるいはユニット後面から台盤２ａの後板貫通孔３ｂ，３ｄに爪を挿入した場合でも、線１２を超えて奥まで爪を挿入するだけで圧縮ユニット２１の安定した、安全な搬送が可能となる。
【００３６】
圧縮ユニット２１の重心１０が圧縮ユニット２１の前後方向中央にある場合、第２補助板部材９の設置は前板貫通孔３ａ，３ｃ、もしくは後板貫通孔３ｂ，３ｄのどちらでもよい。例えば、第２補助板部材９の地面１８に平行の面の長さを、ユニット前面もしくは後面からユニット中央までの距離よりも長くして、爪をユニット中央よりも奥まで挿入すれば、隣接したユニットを傷つけることなく、圧縮ユニット２１の安定した、安全な搬送が可能となる。
【００３７】
このような側面視Ｌ字状の第２補助板部材９の場合、台盤２ａの前面もしくは後面にネジ７で脱着可能に固定される。このことにより、第２補助板部材９は一端側だけを取り外せばすむので、より狭い作業スペースでも製品据付作業が可能となり、ひいては冷凍装置の設置に必要なスペースを小さくできる。また、第２補助板部材９を取り外し可能としたことにより、台盤２下の空間部４６から配管を取り出し、圧縮ユニット２１の前後左右下方向に施工することができる。これにより、配管施工の自在性を確保でき、配管施工がユニット外周を取りまわしすることなく最短で可能となる。従って、配管施工の経済性も向上し、また配管をとりまわすスペースも少なく出来るため、冷凍装置の設置に必要な面積も小さくできる。
【００３８】
発明の実施の形態３．
図７は本発明の実施の形態３に係る台盤を示す斜視図である。図に示した台盤２ｂは、前記の第１補助板部材６を省いて第３補助板部材１３を用いたこと以外、実施の形態１の台盤２と同様の構成である。従って、共通する構成要素には前記の図１、図２、図３、図４と同じ符号を付して重複する説明を省略する。また、台盤２ｂが圧縮ユニット２１の本体ケーシング１の底面部を構成する態様も同様であるので説明を省略する。
前記の第３補助板部材１３は逆Ｔ字状の板金製で左右方向に長く形成されていて、上板部４１の下面に溶接等で固着されている。そして、この第３補助板部材１３は、図８に示すように、台盤２ｂに搭載される圧縮ユニット２１の重心１０の下方位置（線１２が通過する位置）で、かつ、上板貫通孔５，５の下方を避けた空間部４６内の位置に配備されている。すなわち、第３補助板部材１３は上板部４１の下面に、前板部４２または後板部４３とほぼ並行して配置され、その下面１４は前板貫通孔４２の上縁１５ａまたは後板貫通孔４３の上縁１５ｂとほぼ同じ高さに設定されている。
【００３９】
このような構造にすることで、圧縮ユニット２１の前面から台盤２ｂの前板貫通孔３ａ，３ｃにフォークリフトの爪３０を挿入した場合、あるいは圧縮ユニット２１の後面から台盤２ｂの後板貫通孔３ｂ，３ｄに爪３０を挿入した場合でも、重心１０から地面１８に垂直に下ろした点１１を結ぶ線１２よりも奥で、かつ、第３補助板部材１３の下方または第３補助板部材１３の下方を超えるように爪３０を挿入すれば、隣接したユニットを傷つけることなく安定した、安全な搬送が可能となる。
【００４０】
また、台盤２ｂの下に配管を取り出すスペース（空間部４６）を確保しているので、上板貫通孔５から空間部４６内に下方向に配管を取り出し、圧縮ユニット２１の前後左右下方向に施工可能となる。これにより、配管施工の自在性を確保でき、配管施工がユニット外周を取りまわすことなく最短で可能となる。従って、配管施工の経済性も向上し、また配管をとりまわすスペースも少なくできるため、冷凍装置の設置に必要な面積を小さくできる。
【００４１】
また、第３補助板部材１３は台盤２ｂの下面に設置されるので、台盤２ｂの補強も兼ねることになる。この場合、第３補助板部材１３がない場合と比べ、落下等に対する強度が増加する。また、振動を抑える効果があるので、圧縮ユニット２１から発生する騒音も低減することができる。また、第３補助板部材１３がない場合と比べて、台盤本体を構成する板金の板厚を薄くできるので、コスト削減も可能となる。
【００４２】
更には、図９（孔３ｂ，３ｄ，４ｃ，４ｄ，５は図示せず）の如く、第３補助板部材１３に加えて、第３補助板部材１３と直交する向きの第３補助板部材１３ａを上板部４１の下面に設けて、平面視十字状に構成することも可能である。これらは、前面から見た場合も側面から見た場合も圧縮ユニット２１の重心１０から地面に垂直に下ろした線と第３補助板部材１３，１３ａの下面が交わるような位置に第３補助板部材１３，１３ａを設置するとよい。このように構成した場合、側面からもフォークリフトの爪を挿入して搬送することが可能となる。さらには、補強の効果も増すので、台盤２ｂ自体の強度がより増加する。また、圧縮ユニット２１から発生する騒音もいっそう低減できる。
【００４３】
尚、台盤２ｂに設置される第３補助板部材１３としては、逆Ｔ字状のものを使用したが、図１０の如く、圧縮ユニット２１の重心１０から地面１８に垂直に下ろした点１１を結ぶ線１２と板金の水平面が交わるように設置できれば、Ｌ字板金１６（同図（ａ））やコの字状板金１７（同図（ｂ））を使用してもよい。あるいは、垂直に下ろした線１２を挟み込むように配置すれば、同図（ｃ）の如く、Ｌ字板金１６を２つ使用しても同様の効果が得られる。
【００４４】
また、図８中の２点鎖線で示したように、実施の形態１で説明した第１補助板部材６（凹字状板金）、または実施の形態２で説明した第２補助板部材９（Ｌ字状板金）と、第３補助板部材１３（および第３補助板部材１３ａ）とを同時に設置すれば、さらに安定した搬送が可能となる。また、板厚の薄い補助板部材６，９の使用が可能となるから、コスト低減を図ることができる。
【００４５】
【発明の効果】
以上詳述したように、本発明に係る冷凍装置によれば、前板貫通孔と後板貫通孔の間に架け渡された第１補助板部材の両端部が、前板貫通孔の上縁と後板貫通孔の上縁にあてがわれた状態で前板部と後板部に固定手段により脱着可能に取り付けられているので、冷凍サイクル構成部品に関し、安全で安定した搬送、配管施工の自在性、および経済性の向上を図ることができ、本発明に係る冷凍装置の設置に必要な面積も小さくてすむ。また、台盤は腰下機能も兼ね備えているので、冷凍サイクル構成部品の搬送後に木材等の廃材を生じるといったことがない。

BACKGROUND OF THE INVENTION
The present invention relates to a component mounting structure of a refrigeration apparatus that cools the inside of a freezer or the like.
[0002]
[Prior art]
FIG. 11 is a schematic diagram for explaining a system of a general-purpose refrigeration apparatus. The refrigeration apparatus shown in the figure includes a compressor and a compressor unit 21 having components attached to the compressor, a heat radiation unit 22 having a condenser and a blower fan, an evaporator and a fan for cooling the inside of the freezer. It is mainly composed of a cooling unit 23 having a fan. Each of these units is separately placed, but is connected via a refrigerant pipe to form a refrigeration cycle. That is, the compression unit 21 is provided in an indoor machine room or the like, the cooling unit 23 is provided in a freezer for cooling an object to be cooled, and the condensing unit 22 is provided outdoors. Such a method is called a remote method.
In addition, as shown in FIG. 12, an integrated air cooling unit 24 in which a compression unit 21 and a heat radiating unit 22 are integrated is often used, and is generally placed outdoors for exhaust heat of the radiator.
[0003]
FIG. 13 shows a structure described in Patent Document 1 below, and a base plate 52 on which the conventional compression unit 21 (FIG. 11) (or the integrated air cooling unit 24 (FIG. 12)) is placed, and the base plate 52 are arranged. The supporting foot member is mainly shown. In FIG. 13, reference numeral 1 indicates a main body casing such as the compression unit 21 that is a component of the refrigeration cycle, and reference numeral 52 indicates a metal base plate that forms the bottom wall surface of the main body casing 1. On the base plate 52, components such as a refrigerant compressor constituting the refrigeration cycle such as the compression unit 21 and components such as control devices attached thereto are mounted. These components are not shown because they are covered by the main casing 1.
[0004]

JP 2000-65400 A
[0005]
By the way, in the compression unit 21 for cooling a showcase such as an air conditioner or a supermarket, the lower back 25 is used as a member that supports the base plate 52 during transportation. The lower waist 25 is made of wood, and a hole 26 for inserting a claw such as a forklift is formed on the side surface. By supporting the pedestal 52 with the lower waist 25, a claw such as a forklift can be inserted into the hole 26 and conveyed, and the conveyance of the compression unit 21 is facilitated. The lower waist 25 also has a role to prevent the base plate 52 from coming into direct contact with the ground when the compression unit 21 or the like is conveyed.
[0006]
Further, as shown in FIG. 14, the angle member 27 having the hole 26 is combined and installed under the base plate 52 so as to support the outer peripheral edge of the base plate 52 from below so that a forklift or other claw can be passed therethrough. However, there are also those that have the same role as the lower waist described above to facilitate transport. In this case, it is possible to eliminate or reduce the waist that is used only during product transportation and transportation and become waste material, which is also useful for environmental conservation.
[0007]
In Japanese Patent Application No. 2002-135197 filed by the present applicant, a plurality of foot members formed by bending a metal plate material are attached to the lower surface of the base plate substantially in parallel to each other, and the base plate is supported by these foot members. There is something to do. With such a structure, it becomes possible to reduce the volume, height, and mass of the foot member, reduce the material cost and processing cost of the foot member, reduce the packing height and the packing mass, and the accompanying conveyance cost. We are also trying to improve the installation.
[0008]
Further, in addition to the structure shown in the paragraph number 0007, as shown in FIG. 15, an angle member 27 having a hole 26 for forklift pawl insertion is combined and installed below the base plate 52, and the angle members before and after that are installed. A structure in which a bridging member 28 is bridged between the upper left and right edge portions of the holes 26 and 26 of the holes 27 and 27 is also common.
[0009]
Further, the foot member described in the paragraph number 0007 can be attached to and detached from the base plate. As a result, if it is desirable to increase the height of the unit, for example, if the drainage at the installation site is poor, install with the foot member attached to the base plate, and if unnecessary, remove the foot member from the base plate and install it. Thus, it is possible to select according to the situation of the installation site, so that the installation property is further improved.
[0010]
Conventionally, piping connection to a box-shaped compression unit or other unit of an air conditioner has been performed by forming piping connection holes 29 in the main casing 1 as shown in FIG. In this case, the main body casing 1 has a structure that makes it easy for the user to provide the connection holes 29 by, for example, making a cut in a hole shape in advance in the front panel or the right panel.
[0011]
In addition, in the case of the integrated air cooling type (FIG. 12), since there are only two pipes to be connected, the structure for inserting the forklift claw under the base plate by combining the angle members as described above is shown in FIG. As shown in FIG. 17, by providing a pipe connection hole 33 (notch) in the horizontal plane portion of the angle member 27, the pipe 8 can be taken out downward or out of the angle member 27, and then pipe construction can be performed in the front / rear / left / right lower direction of the unit. It is.
[0012]
[Problems to be solved by the invention]
The conventional apparatus is configured as described above. In the case of a structure in which a space is formed under the base plate 52 by combining the angle members 27, a cross-sectional view is as shown in FIG. In this structure, when the unit is installed adjacent to another unit 31 during storage in a warehouse or during transportation of a unit on a truck, the forklift pawl 30 protrudes from the angle member on the back side of the unit and is transported. The possibility of damaging the adjacent unit 31 at the tip of the nail 30 is increased. On the contrary, when the claw 30 is transported so that the adjacent unit 31 is not damaged so that the claw 30 hardly protrudes, the tip of the claw 30 comes off from the angle member on the back side of the unit and comes into contact with the back surface of the table 52 to damage the table 52. Or, the compression unit 21 may fall over.
[0013]
On the other hand, as shown in FIG. 19, if the length of the horizontal portion 32 is increased by shortening the distance between the front angle member and the rear angle member, the claw 30 protrudes from the vertical portion of the rear angle member to some extent. However, it does not protrude from the main body casing 1, that is, does not damage the unit 31 placed adjacently. In the case of this structure, even in the case of the remote-type compression unit 21 having as many as four connecting pipes, the pipes can be taken out from under the base plate 52 and installed in the front, rear, left, and right directions of the main body casing 1.
[0014]
However, in the case of this structure, since the lower horizontal portion 32 of the angle member is weak against the drop strength, reinforcement is required. Further, since the upper horizontal portion 32 also needs to support a heavy member such as a compressor, reinforcement is required. Further, when the claw 30 is inserted, the unit 21 (or 24) becomes unstable during transportation because the distance between the vertical portions of the front side angle member and the back side angle member is short.
[0015]
Alternatively, as shown in FIG. 15, if the bridging member 28 is bridged over the upper left and right edge portions of the front and rear angle members 27, 27, the forklift pawl is inserted partway through the bridging member 28. The unit can be transported without damaging it. In this case, in order to take out the pipe from the bottom of the base plate 52 and construct the units 21 and 24 in the front, rear, left and right directions, the pipe can be taken out to the inner side of the angle members 27, 27, 27, 27 surrounded by the squares. Thus, it is necessary to make holes in the base plate 52 and the angle member 27.
[0016]
However, in the case of a unit structure with a narrow width as shown in FIG. 20, an angle member surrounded by a square is used so that the pipe can be taken out from under the base plate 52 and can be constructed in the front, rear, left, and right direction. Even if a hole 29 or the like is made in the base plate 52 or the angle member 27 so that the piping can be taken out from the inner side of the 27, 27, 27, 27, the bridging member 28 interferes and the construction is impossible. In this case, at the time of piping construction, it may be necessary to route the piping around the outer periphery of the main casing 1 as shown in FIG. 16. In this case, the construction piping length becomes long and the economic efficiency deteriorates. In addition, a space for piping is required, and the area required for installing the refrigeration apparatus also increases.
[0017]
The present invention has been made to solve the above-described problems, and enables safe and stable transport even when a unit constituting the refrigeration apparatus is adjacent to another unit. While securing the strength of the panel etc., the piping can be taken out from the bottom of the baseboard during piping construction and can be installed freely in the front / rear / left / right direction of the unit, ensuring the flexibility of piping construction, economic efficiency, or after transporting the unit An object is to provide a refrigeration apparatus capable of reducing waste materials such as generated wood.

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 of the Invention
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view showing a base plate according to Embodiment 1 of the present invention, and FIG. 2 is a side sectional view of the base plate according to Embodiment 1 of the present invention.
In each drawing, the refrigeration apparatus of this embodiment includes components (for example, a compressor and an oil separator) constituting a compression unit of a refrigeration cycle and components incidental to these components (for example, electric parts for control, etc.). For example, it is mounted on a base plate 2 made of sheet metal. Although these parts are installed and fixed on the base plate 2, illustration is omitted here, and only the main body casing 1 (see FIG. 4) of the compression unit 21 is shown. The base plate 2 includes an upper plate portion 41 having a substantially rectangular shape in plan view on which the components of the compression unit 21 surrounded by the main body casing 1 are placed, and a front surface provided to hang from the front side of the upper plate portion 41. On the left side of the upper plate 41, the plate 42, the rear plate 43 provided to hang on the rear side of the upper plate 41, the side plate 44 provided on the right side of the upper plate 41, and And a side plate portion 45 provided to hang down, and the entire bottom surface is open. Accordingly, the base plate 2 has a space 46 between the front plate portion 42, the rear plate portion 43, the side plate portion 44, and the side plate portion 45 below the upper plate portion 41.
[0024]
A plurality of upper plate through-holes 5 for taking out pipes are formed in the upper plate portion 41, and front plate through-holes 3a and 3c for inserting forklift claws and pipes are formed side by side in the front plate portion 42. Rear plate through-holes 3b and 3d for forklift claw insertion and piping take-out are formed in the rear plate portion 43 at positions facing these front plate through-holes 3a and 3c, respectively. In this case, one of the two claws of the forklift is inserted into the holes 3a and 3b, and the other claw is inserted into the holes 3c and 3d. In the side plate portion 44, side plate through holes 4a and 4b for forklift claw insertion and piping take-out are formed side by side. Side plate through holes 4c and 4d for forklift claw insertion and pipe take-out are also formed in the side plate portions 45 at positions facing these side plate through holes 4a and 4b, respectively. These holes 3a, 3b, 3c, 3d and the holes 4a, 4b, 4c, 4d are also used as holes for passing piping to the cooler and radiator after the product is loaded.
[0025]
Then, one of the first auxiliary plate members 6 formed of a sheet metal in a concave shape when viewed from the side is bridged between the front plate through hole 3a and the rear plate through hole 3b, and the other first auxiliary plate member 6 is It spans between the front plate through hole 3c and the rear plate through hole 3d. These first auxiliary plate members 6 and 6 can be attached to and removed from the front plate portion 42 with screws 7 (an example of fixing means) with one end applied to the upper edges 15a and 15a of the front plate through holes 3a and 3c. It is attached. The other ends of the first auxiliary plate members 6 and 6 are detachably attached to the rear plate portion 43 with screws 7 (an example of fixing means) in a state where they are applied to the upper edges 15b and 15b of the rear plate through holes 3b and 3d. It has been.
The structure of the base plate 2 is not limited to a box type that also functions as a lower back as shown in FIG. 1, but has a hole 26 through which a claw such as a forklift as described in the prior art can pass. A structure in which the angle member 27 (FIGS. 14, 15, 17, 18, and 20) is combined and installed so as to support the outer peripheral edge of the base from below is also possible.
[0026]
As described above, since the first auxiliary plate member 6 is provided on the base plate 2, the forklift pawl 30 protrudes from the rear plate through-holes 3b and 3d (not shown) on the back as shown in FIG. The unit can be lifted and conveyed without causing it to move. Thus, even when the unit is adjacent to another unit, the adjacent unit is not damaged. Further, since the claw 30 of the forklift does not have to reach the rear plate through holes 3b, 3d on the back side, the claw 30 comes off from the rear plate through holes 3b, 3d and comes into contact with the back of the base plate 2 2 can be safely and stably transported without damaging the unit 2 and without causing the unit to fall over.
[0027]
On the other hand, since the first auxiliary plate member 6 is detachably fixed with screws 7 or the like, after connecting the product, the screws 7 are removed and the first auxiliary plate member 6 is removed, so that there are as many as four connecting pipes. Even in the case of the compression unit 21 of the type, the pipe 8 (8a, 8b, 8c) is taken out from the base 2 as shown in FIG. Piping can be done. For the sake of clarity, the drawing shows only the left side piping path 8a, the front side piping path 8b, and the lower side piping path 8c, and the rear side and the right side are omitted. is there. Further, the rear plate through holes 3b and 3d on the back surface of the base plate 2 and the side plate through holes 4c and 4d on the side surfaces are also omitted, but piping can also be performed on these sides.
In this way, the piping 8 can be taken out from the space 46 under the base plate 2 and can be installed in the front / rear / right / left direction of the compression unit 21 to ensure the flexibility of piping construction. It is possible in the shortest without doing. Accordingly, the economics of piping construction can be improved and the space surrounding the piping can be reduced, so that the area required for installing the refrigeration apparatus can also be reduced.
[0028]
The side plate through-holes 4a to 4d of the base plate 2 have been described as holes for allowing piping to pass therethrough. The same effect as described in paragraph 0027 above can be obtained.
[0029]
Moreover, since the base plate 2 also serves as a lower back function, it is possible to reduce waste materials such as wood generated after the unit is transported.
[0030]
In the first embodiment, the screw 7 is exemplified as a means for fixing the first auxiliary plate member 6, but any means may be used as long as the first auxiliary plate member 6 is detachably fixed. It is conceivable to employ various fixing means other than 7, for example, a combination of a hook and a locking hole, a combination of a bolt and a nut, and other structures.
[0031]
In the first embodiment, the first auxiliary plate member 6 has a concave shape when viewed from the side. However, the first auxiliary plate member 6 can be bridged between the holes 3a and 3b of the base plate 2 and between the holes 3c and 3d. Any structure can be used as long as it can be fixed in a removable manner. It is also possible to adopt a shape other than the concave shape. The same effect can be obtained when an auxiliary plate member that bridges between the holes 4a and 4c of the base plate 2 and between the holes 4b and 4d is employed.
[0032]
Embodiment 2 of the Invention
FIG. 5 is a perspective view showing a base plate according to Embodiment 2 of the present invention. The base plate 2a shown in the figure has the same configuration as the base plate 2 of the first embodiment except that the second auxiliary plate member 9 is used instead of the first auxiliary plate member 6 described above. Therefore, the same components as those shown in FIGS. 1, 2, 3, and 4 are given the same reference numerals, and redundant descriptions are omitted. Moreover, since the aspect in which the base board 2a comprises the bottom face part of the main body casing 1 of the compression unit 21 is also the same, description is abbreviate | omitted.
[0033]
The second auxiliary plate members 9 and 9 are formed in, for example, sheet metal in an L shape in a side view, and in a state where each one end side is applied to the upper edges 15a and 15a of the front plate through holes 3a and 3c, One end is detachably attached to the front plate portion 42 by a screw 7 (an example of a fixing means). Incidentally, the second auxiliary plate member 9 corresponds to the position of the center of gravity 10 of the compression unit 21, for example, if the center of gravity 10 of the compression unit 21 is at the front side of the unit, as shown in FIG. 9 is installed in the front plate through-holes 3a and 3c of the base plate 2a. Here, the length of the surface parallel to the ground surface 18 of the second auxiliary plate member 9 in FIG. 6 may be longer than the distance A from the front surface of the main casing 1 to the center of gravity 10. That is, the other end 47 of the second auxiliary plate member 9 extends toward the rear plate through holes 3b and 3d and is lowered vertically from the center of gravity 10 of the compression unit 21 mounted on the base plate 2 toward the ground 18. It is arranged beyond the line 12 connecting the points 11. In this way, when forklift claws are inserted into the front plate through holes 3a and 3c of the base plate 2a from the front of the unit, or when nails are inserted into the rear plate through holes 3b and 3d of the base plate 2a from the rear of the unit. However, if the claw of the forklift is inserted deeply beyond the line 12, the compression unit 21 can be stably and safely conveyed.
[0034]
The second auxiliary plate member 9 has one end detachably attached to the rear plate portion 43 with screws 7 (an example of fixing means) and one end side attached to the upper edges 15b, 15b of the rear plate through holes 3b, 3d. The other end 47 applied may extend toward the front plate through-holes 3a and 3c.
[0035]
On the other hand, when the center of gravity 10 of the compression unit 21 is at the position on the rear side of the unit, one end of the second auxiliary plate member 9 is installed in the rear plate through holes 3b and 3d of the base plate 2a and the other end 47 is the front plate through hole. It extends toward 3a, 3c. Also in this case, the length of the surface of the second auxiliary plate member 9 parallel to the ground surface 18 may be longer than the distance from the rear surface of the compression unit 21 to the center of gravity 10. Thus, as described above, when forklift claws are inserted into the front plate through holes 3a and 3c of the base plate 2a from the front of the unit, or into the rear plate through holes 3b and 3d of the base plate 2a from the rear surface of the unit. Even in this case, the compression unit 21 can be stably and safely conveyed only by inserting the claw beyond the line 12 to the back.
[0036]
When the center of gravity 10 of the compression unit 21 is in the center in the front-rear direction of the compression unit 21, the second auxiliary plate member 9 may be installed in either the front plate through holes 3a, 3c or the rear plate through holes 3b, 3d. For example, if the length of the surface parallel to the ground surface 18 of the second auxiliary plate member 9 is longer than the distance from the front or rear surface of the unit to the center of the unit and the claws are inserted deeper than the center of the unit, they are adjacent to each other. The compression unit 21 can be stably and safely transported without damaging the unit.
[0037]
In the case of such a second auxiliary plate member 9 having an L shape in side view, the second auxiliary plate member 9 is detachably fixed to the front surface or the rear surface of the base plate 2a with screws 7. As a result, the second auxiliary plate member 9 only needs to be removed at one end side, so that product installation work can be performed even in a narrower work space, and as a result, the space required for installing the refrigeration apparatus can be reduced. In addition, since the second auxiliary plate member 9 can be removed, the pipe can be taken out from the space 46 under the base plate 2 and can be applied in the front, rear, left, and right directions of the compression unit 21. Thereby, the flexibility of piping construction can be ensured, and piping construction is possible in the shortest time without surrounding the unit periphery. Therefore, the economics of piping construction can be improved, and the space surrounding the piping can be reduced, so that the area required for installing the refrigeration apparatus can be reduced.
[0038]
Embodiment 3 of the Invention
FIG. 7 is a perspective view showing a base plate according to Embodiment 3 of the present invention. The base plate 2b shown in the figure has the same configuration as the base plate 2 of the first embodiment except that the first auxiliary plate member 6 is omitted and the third auxiliary plate member 13 is used. Therefore, the same components as those shown in FIGS. 1, 2, 3, and 4 are given the same reference numerals, and redundant descriptions are omitted. Moreover, since the aspect in which the base board 2b comprises the bottom face part of the main body casing 1 of the compression unit 21 is the same, description is abbreviate | omitted.
The third auxiliary plate member 13 is made of an inverted T-shaped sheet metal and is formed long in the left-right direction, and is fixed to the lower surface of the upper plate portion 41 by welding or the like. As shown in FIG. 8, the third auxiliary plate member 13 is located below the center of gravity 10 of the compression unit 21 mounted on the base plate 2b (a position through which the line 12 passes) and has an upper plate through hole. It is arranged at a position in the space 46 that avoids the lower portions of 5 and 5. That is, the third auxiliary plate member 13 is disposed on the lower surface of the upper plate portion 41 substantially in parallel with the front plate portion 42 or the rear plate portion 43, and the lower surface 14 thereof is the upper edge 15 a of the front plate through hole 42 or the rear plate. The height is set substantially the same as the upper edge 15 b of the through hole 43.

With such a structure, when the forklift claw 30 is inserted from the front surface of the compression unit 21 into the front plate through holes 3a and 3c of the base plate 2b, or the rear plate of the base plate 2b passes through the rear surface of the compression unit 21. Even when the claw 30 is inserted into the holes 3b and 3d, it is behind the line 12 connecting the point 11 that is lowered from the center of gravity 10 to the ground 18 and below the third auxiliary plate member 13 or the third auxiliary plate member. If the nail | claw 30 is inserted so that the downward direction of 13 may be inserted, the stable and safe conveyance will be attained, without damaging an adjacent unit.
[0040]
Moreover, since the space (space part 46) which takes out piping under the base board 2b is ensured, piping is taken out into the space part 46 from the upper board through-hole 5, and the front-back, left-right, and downward direction of the compression unit 21 Construction is possible. Thereby, the flexibility of piping construction can be ensured, and piping construction is possible in the shortest without surrounding the unit periphery. Therefore, the economical efficiency of piping construction can be improved and the space for piping can be reduced, so that the area required for installing the refrigeration apparatus can be reduced.
[0041]
Moreover, since the 3rd auxiliary | assistant board member 13 is installed in the lower surface of the base plate 2b, it will also serve as reinforcement of the base plate 2b. In this case, compared with the case where the third auxiliary plate member 13 is not provided, the strength against dropping or the like increases. Further, since there is an effect of suppressing vibration, noise generated from the compression unit 21 can also be reduced. In addition, compared to the case where the third auxiliary plate member 13 is not provided, the thickness of the sheet metal constituting the base body can be reduced, so that the cost can be reduced.
[0042]
Further, as shown in FIG. 9 (the holes 3b, 3d, 4c, 4d, and 5 are not shown), in addition to the third auxiliary plate member 13, the third auxiliary plate member oriented perpendicular to the third auxiliary plate member 13 13a may be provided on the lower surface of the upper plate portion 41 to form a cross shape in plan view. The third auxiliary plate is located at a position where the line perpendicular to the ground from the center of gravity 10 of the compression unit 21 and the lower surface of the third auxiliary plate members 13 and 13a intersect both when viewed from the front and from the side. The members 13 and 13a may be installed. When constituted in this way, it becomes possible to insert a claw of a forklift from the side and carry it. Furthermore, since the effect of reinforcement is also increased, the strength of the base plate 2b itself is further increased. Further, noise generated from the compression unit 21 can be further reduced.
[0043]
As the third auxiliary plate member 13 installed on the base plate 2b, an inverted T-shaped member is used. However, as shown in FIG. 10, the point 11 is vertically lowered from the center of gravity 10 of the compression unit 21 to the ground 18. If it can install so that the line 12 which ties and the horizontal surface of a sheet metal may cross | intersect, you may use the L-shaped sheet metal 16 (the figure (a)) and the U-shaped sheet metal 17 (the figure (b)). Or if it arrange | positions so that the line | wire 12 pulled down perpendicularly may be inserted | pinched, even if it uses two L-shaped sheet metal 16 like the figure (c), the same effect will be acquired.
[0044]
Further, as indicated by a two-dot chain line in FIG. 8, the first auxiliary plate member 6 (concave metal plate) described in the first embodiment or the second auxiliary plate member 9 (described in the second embodiment) ( If the L-shaped sheet metal) and the third auxiliary plate member 13 (and the third auxiliary plate member 13a) are installed at the same time, further stable conveyance is possible. In addition, since the auxiliary plate members 6 and 9 having a small plate thickness can be used, the cost can be reduced.
[0045]
【The invention's effect】
As described above in detail, according to the refrigeration apparatus according to the present invention, the both ends of the first auxiliary plate member spanned between the front plate through hole and the rear plate through hole are the upper edges of the front plate through hole. And attached to the upper edge of the rear plate through-hole in the front plate portion and the rear plate portion by a fixing means, so that it can be safely and stably transported and piped for refrigeration cycle components. The flexibility and economy can be improved, and the area necessary for installing the refrigeration apparatus according to the present invention can be reduced. In addition, since the base plate also has a lower back function, there is no occurrence of waste materials such as wood after transporting the refrigeration cycle components.
