Description

【0001】
【発明の属する技術分野】
この発明は、天井設置型空気調和装置、特に吸い込み口を背面あるいは下面に付け替えることができる天井設置型空気調和装置に関するものである。
【0002】
【従来の技術】
図4は、この種天井設置型空気調和装置の従来の構成を示す概略図で、(a)は吸い込み口が背面に設けられた場合、(b)は同じく下面に設けられた場合を示す。これらの図において、1は天井空間に設置される空気調和装置の本体で、天板11と、側板12と、底板13とから構成され、背面となる一端側(図において左端)または下面に設けられ、それぞれ同寸法とされた吸い込み口14と、他端側(図において右端)に設けられた吹き出し口15を有し、被空調空間(図示せず)からの空気16と、熱交換して上記被空調空間に供給する空気17の通風路を形成している。2は吸い込み口14と被空調空間の吸い込み口とを接続するダクト、3は吸い込み口14に設けられたフィルターで、吸い込み口の内側の上下にそれぞれネジ4で固定されたフィルターレール5A、5Bに保持されている。
【0003】
6はフィルターが設けられていない吸い込み口14を閉塞する閉塞板、7は本体1の通風路内で背面または下面の吸い込み口14と吹き出し口15との間に設けられた送風機、71は送風機7を固定する送風機台、8は通風路内で送風機7と吹き出し口15との間に設けられた熱交換器、9は熱交換器8の下方に設けられ、底板13に形成された孔18を通して、熱交換器8によって凝縮されたドレン水を貯留するドレンパンである。
【0004】
【発明が解決しようとする課題】
従来の天井設置型空気調和装置は以上のように構成されているため、図4(a)に示すように、背面に吸い込み口14が設けられている場合には、被空調空間の空気16がダクト2及び背面吸い込み口14のフィルター3を介して通風路内に入り、熱交換器8によって熱交換され、熱交換後の空気17が吹き出し口15から被空調空間に吹き出される。図4(b)の場合は、被空調空間の空気が下方から吸い込まれるが、その後は上記と同様である。この場合、フィルター3はフィルターレール5A、5Bによって保持されているため、送風機7の風によって吸引されることはない。しかし、フィルター3の点検、洗浄等に際して閉塞板6を取り外しても、フィルター3はフィルターレール5A、5Bによって保持されているため取り外すことができないという問題点があった。
この発明は、このような問題点を解消するためになされたもので、閉塞板を取り外すことによりフィルターを容易に取り外すことができる天井設置型空気調和装置を提供することを目的とする。
【0005】
【課題を解決するための手段】
この発明に係る天井設置型空気調和装置は、天井空間に設置されほぼ同寸法とされた背面吸い込み口と下面吸い込み口の2つの吸い込み口と、吹き出し口とを有する通風路、上記背面吸い込み口または下面吸い込み口に装着し得るようにされ、一端側に係止部と、この係止部に間隔を介して対向する挟持部とを設けた閉塞板、上記閉塞板が装着されていない吸い込み口に設けられ、端部が上記閉塞板の係止部と挟持部とで保持されたフィルター、上記通風路内の背面吸い込み口または下面吸い込み口と吹き出し口との中間部に設けられた送風機、この送風機の吹き出し口側に設けられた熱交換器及びこの熱交換器の下方に設けられたドレンパンを備えたものである。
【0006】
この発明に係る天井設置型空気調和装置は、また、上記閉塞板の挟持部を弾性材で形成したものである。
【0007】
この発明に係る天井設置型空気調和装置は、また、上記閉塞板の係止部と挟持部との間隔を上記フィルターの厚さより僅かに小さくしたものである。
【0008】
この発明に係る天井設置型空気調和装置は、また、上記閉塞板の係止部が閉塞板の端部をL字状に折り曲げることによって形成されたものである。
【0009】
【発明の実施の形態】
実施の形態1.
以下、この発明の実施の形態1を図にもとづいて説明する。図1は、実施の形態1の構成を示す概略図で、吸い込み口が背面に設けられている場合を示し、(a)はフィルター及び閉塞板の装着状態、(b)は閉塞板を取り外した状態を示す。
また、図2は、同じく吸い込み口が下面に設けられている場合を示し、(a)はフィルター及び閉塞板の装着状態、(b)は閉塞板を取り外してフィルターを引き出した状態を示す。これらの図において、図4と同一または相当部分にはそれぞれ同一符号を付して説明を省略する。図4と異なる点は、閉塞板の一端側に係止部及びこれと間隔を介して対向する挟持部を設け、フィルターの端部を上記係止部と挟持部との間に挟み込んで保持するようにした点である。即ち、図1において、11は本体1の天板で、吸い込み口14に面する端部を図1(b)に示す閉塞板60の係止部61と同様にL字状に折り曲げて係止部11Aとしている。
また、11Bは係止部11Aに対してフィルター3の厚さより僅かに小さい間隔を介して天板11に設けられた挟持部で、弾性材によって形成されている。
【0010】
60は下面の吸い込み口14を閉塞する閉塞板で、図1(b)に示すように、一端部をL字状に折り曲げて係止部61を形成すると共に、係止部61に対してフィルター3の厚さより僅かに小さい間隔を介して挟持部62が設けられている。挟持部62は弾性材によって形成されている。なお、係止部61は折り曲げによる形成に限られるものではなく、閉塞板60の先端部に適宜の寸法の板状部材を固着することによって形成してもよい。フィルター3は図1(a)に示すように、上端を天板11の係止部11Aと挟持部11Bとの溝に下方から押し込む形で挟持させ、フィルター3の下端に対しては下方から閉塞板60の係止部61と挟持部62との溝を当接させ、係止部61と挟持部62との溝にフィルター3の下端を挿入させた状態で閉塞板60を本体1の側板12にネジ止めする。
フィルター3は上述のように、上下端がそれぞれ天板11と閉塞板60によって挟持されるため、送風機7の風によって吸引されることはない。
【0011】
フィルター3の点検、洗浄等の際には、図1(b)に示すように、閉塞板60を取り外すと、閉塞板60の係止部61と挟持部62がフィルター3の下端から外れるが、フィルター3の上端が天板11の係止部11Aと弾性材の挟持部11Bとによって挟持されているため、落下することなく保持されている。この状態でフィルター3を図1(b)に矢印で示すように、下方に引くことにより容易に取り外すことができる。一方、吸い込み口14を下面に付け替える場合には、図1(a)の閉塞板60を取り外して背面の吸い込み口14に装着する。
この場合、係止部61と挟持部62が設けられている端部を図2(a)に示すように、下側にして装着する。また、図2(a)に示されているように、送風機台71の下端部が図において左方に折り曲げられていて、フィルター3の図において右端を下方から支持する支持部72を構成すると共に、この支持部の右端に弾性材からなる挟持部73が固定されている。
【0012】
従って、フィルター3の装着は、図においてフィルター3の右端を送風機台71の下端の支持部72上に載せると共に、フィルター3の右端を挟持部73に当接させる。また、閉塞板60の係止部61と挟持部62との溝を図2において左方からフィルター3の左端に当接させてフィルター3を溝内に挿入する。
この状態で閉塞板60を本体1の側板12にネジ止めする。フィルター3の右端は支持部72と挟持部73と送風機台71とで保持され、左端は閉塞板60の係止部61と挟持部62とで挟持されるため、送風機7の風によって吸引されることはない。フィルター3のメンテナンスに際しては、図2(b)に示すように、閉塞板60を取り外すと、フィルター3はフリーになるため、矢印で示すように、図において左方に引き出すことにより、フィルター3を容易に取り外すことができる。
【0013】
実施の形態2.
次に、この発明の実施の形態2を図にもとづいて説明する。図3は、実施の形態2の構成を示す概略図で、吸い込み口が背面に設けられている場合を示し、(a)は平面図、(b)は側面図である。この図において、図1と同一または相当部分にはそれぞれ同一符号を付して説明を省略する。
実施の形態2は、実施の形態1を例えば寒冷地で実施する場合のもので、被空調空間の温度が低い時、設定温度に近づけるまでの時間を短縮する目的で電気ヒータが使用されるが、この電気ヒータには温度制御のためのサーモと安全確保のためのヒューズが備えられているため、ヒューズ切れ等に対応するヒータのメンテナンスを容易にするためのものである。
【0014】
図3において、10は送風機7と熱交換器8との間に設けられた電気ヒータで、その取付部101を本体1の側板12に固定されたL字状の金具102にネジ103によって固定したものである。電気ヒータ10を下側からメンテナンスする場合、通常は、ドレンパン9を取り外さなければならず、そのためにはドレンパン9に接続されたドレン配管等も取り外す必要があるため、非常に手間と時間のかかるものであったが、この実施の形態によれば、閉塞板60を取り外し、送風機台71に固定された送風機7を図3(b)に矢印で示すように取り外すことにより、本体1の内部に作業者が入り、電気ヒータ10を取り外すことなく電気ヒータ10のヒューズの取り替え等を行なうことができる。閉塞板60と送風機7の取り外しは、ドレンパン9の取り外しのように配管の取り外しを伴なわないため短時間で作業を完了させることができる。
【0015】
【発明の効果】
この発明に係る天井設置型空気調和装置は、天井空間に設置されほぼ同寸法とされた背面吸い込み口と下面吸い込み口の2つの吸い込み口と、吹き出し口とを有する通風路、上記背面吸い込み口または下面吸い込み口に装着し得るようにされ、一端側に係止部と、この係止部に間隔を介して対向する挟持部とを設けた閉塞板、上記閉塞板が装着されていない吸い込み口に設けられ、端部が上記閉塞板の係止部と挟持部とで保持されたフィルター、上記通風路内の背面吸い込み口または下面吸い込み口と吹き出し口との中間部に設けられた送風機、この送風機の吹き出し口側に設けられた熱交換器及びこの熱交換器の下方に設けられたドレンパンを備えたものであるため、閉塞板を取り外すことにより容易にフィルターを取り外すことができ、据え付けに際しての制約事項が少なくなりメンテナンス性を向上することができる。
【0016】
この発明に係る天井設置型空気調和装置は、また、上記閉塞板の挟持部を弾性材で形成したものであるため、フィルターが背面吸い込み口に設けられている場合でも、下面閉塞板の取り外し時にフィルターが落下することがなく、メンテナンスが容易となる。
