Description

【０００１】
【発明の属する技術分野】
本発明は、室内熱交換器と室外熱交換器とを本体内に収容する、いわゆる一体形の空気調和機において、冷房運転時に生成されるドレン水の処理構造の改良に関する。
【０００２】
【従来の技術】
たとえば、エレベータ装置を構成するゴンドラ（以下、単にエレベータと言う）天井部に、エレベータ内部を冷房し、もしくは暖房する空気調和機が載設される。この空気調和機は、冷凍サイクルを利用し、本体内に室内熱交換器と室外熱交換器を備えた、いわゆる一体形のものが用いられる。
【０００３】
冷房運転時には、室内熱交換器で熱交換される空気の露点が低下して水分が凝縮し、ドレン水となって滴下する。この室内熱交換器の下部にはドレンパンが配置され、全てのドレン水が集溜される。このドレン水は室外熱交換器側に導びかれて掻き上げられ、この熱交換器に散水することで熱交換効率の向上化を得るとともに、ドレン水の蒸発処理がなされる。
【０００４】
具体的には、室外送風機のファン外周にスリンガリングを取付け、この一部をドレン水に浸漬させる。室外送風機を回転駆動すると、ファンが室外熱交換器に外気を送風し、リングがドレン水を掻き上げる。ドレン水は水滴化して外気に混合し室外熱交換器に降りかかる。
【０００５】
あるいは、通常のタイプの室外送風機に並設して、専用の掻き上げ部材を備える場合もある。これは、モータに連結する回転板の周縁に沿って掻き上げ部を備え、この回転板を回転駆動して遠心方向に水を掻き上げる。同時に室外送風機による送風作用をなし掻き上げたドレン水を風に乗せて室外熱交換器に送る。
【０００６】
【発明が解決しようとする課題】
ところで、スリンガリングを取付けた室外送風機の場合も、通常タイプの室外送風機と掻き上げ部材を並設した場合も、いずれも室外熱交換器の風上側に配置され、室外熱交換器へ外気を吹付けることには変りがない。
【０００７】
しかしながら、上記室外熱交換器は多数枚のフィンを狭小の間隙を存して並べた構成であり、外気の強い風が吹付けられることによって抵抗となる。また、特に室外熱交換器の送風機対向面に風が強く当り、周辺部は弱くなるというようにムラがあり、風切り音や水切り音が発生して騒音の原因となっていた。
【０００８】
これら騒音を低減するためには、室外送風機を室外熱交換器の風下側に配置して、本体内に吸込んだ外気を室外熱交換器に直接導き、そのあとこの送風機を介して外部に排出するとよい。
【０００９】
しかしながら、ドレン水の蒸発処理の点から考慮すると、室外熱交換器は室外送風機の吸込み側に位置して、吹出し側には存在しないから、スリンガリングもしくは掻き上げ部材が掻き上げたドレン水は室外熱交換器にかかることなく全て外部に排出して、ドレン水蒸発処理が不可能になる。
【００１０】
本発明は、上述の事情を考慮してなされたものであり、その目的とするところは、本体内に室内熱交換器と室外熱交換器とを収容配置した一体形であり、かつ室内熱交換器で生成されるドレン水を室外熱交換器へ飛散させて蒸発処理することを前提として、風切り音等の騒音の低減を得るとともにドレン水蒸発処理の効率向上化を得る空気調和機を提供しようとするものである。
【００１１】
【課題を解決するための手段】
本発明の空気調和機は上述の目的を満足するためになされていて、筐体からなる空気調和機本体と、この空気調和機本体内に仕切り手段を介して設けられる室内側ユニット部および室外側ユニット部とを具備し、室内側ユニット部は、室内吸込み口および室内吹出し口と、室内吸込み口から吸込まれた空気と熱交換しドレン水を受けるドレンパン上に立位する室内熱交換器と、室内吸込み口から室内空気を吸込み室内熱交換器に導いて熱交換させ室内吹出し口から室内へ送風する室内送風機とを備え、室外側ユニット部は、空気調和機本体の側面板に設けられる外気吸込み口、および背面板に設けられる吹出し口と、空気調和機本体内部に背面板と所定の空間を存し存して長手方向のほぼ中央部に、背面板と略平行な幅方向に亘って配置され所定間隙を存して並置される複数枚のフィンに熱交換パイプを貫通させたフィンドチューブタイプであり、少なくとも一方端側は所定曲率で曲成する曲成部が設けられ各曲成部から側面板に沿って直状に延出し外気吸込み口に対向する延設部が連設される室外熱交換器と、この室外熱交換器と背面板との空間に配置され外気吸込み口から吸込んだ外気を室外熱交換器を介して吹出し口から外部へ吹出す室外送風機と、この室外送風機とは室外熱交換器を介して反対側の部位に、回転にともなってドレンパンから導いたドレン水を遠心方向に掻き上げる回転板を備え、この回転板の遠心方向が室外熱交換器の曲成部と対向するよう配置される掻き上げ手段とを具備し、冷房運転時に室内熱交換器で生成されるドレン水を掻き上げ手段によって掻き上げて外気吸込み口に対向する上記室外熱交換器の延設部から導入される外気と混合させ、室外熱交換器に飛散させて蒸発処理する。
【００１７】
また、本発明の空気調和機は上述の目的を満足するためになされていて、エレベータ装置を構成するゴンドラの天井部に載設される筐体からなる空気調和機本体と、この空気調和機本体内に仕切り手段を介して設けられる室内側ユニット部および室外側ユニット部とを具備し、室内側ユニット部は、ゴンドラ内に連通する室内吸込み口および室内吹出し口と、室内吸込み口から吸込まれたゴンドラ内の空気と熱交換しかつドレン水を受けるドレンパン上に立位する室内熱交換器と、室内吸込み口から室内空気を吸込んで室内熱交換器に導き熱交換した空気を室内吹出し口からゴンドラ内へ送風する室内送風機とを備え、室外側ユニット部は、空気調和機本体の側面板に設けられる外気吸込み口および背面板に設けられる吹出し口と、空気調和機本体内部に背面板と所定の空間を存して長手方向のほぼ中央部に、背面板と略平行な幅方向に亘って配置され所定間隙を存して並置される複数枚のフィンに熱交換パイプを貫通させたいわゆるフィンドチューブタイプであり、少なくとも一方端側は所定の曲率で曲成する曲成部が設けられるとともに各曲成部から側面板に沿って直状に延出し外気吸込み口に対向する延設部が連設される室外熱交換器と、この室外熱交換器と背面板との空間に配置され外気吸込み口から吸込んだ外気を室外熱交換器を介して吹出し口から外部へ吹出す室外送風機と、この室外送風機とは室外熱交換器を介して反対側の部位にドレンパンから導いたドレン水を掻き上げる回転板を備え、回転板の遠心方向が室外熱交換器の曲成部に対向するよう配置される掻き上げ手段とを具備し、冷房運転時に、室内熱交換器で生成されるドレン水を掻き上げ手段によって掻き上げて外気吸込み口に対向する上記室外熱交換器の延設部から導入される外気と混合させ室外熱交換器に飛散させて蒸発処理する。
【００１８】
このような構成を採用することにより、室外送風機の吸込み側に室外熱交換器が位置して、室外熱交換器に外気を吹付けることがないので風切り音等の騒音が低減し、室内熱交換器で生成されるドレン水を室外熱交換器に飛散させ確実に蒸発処理する。
【００１９】
【発明の実施の形態】
以下、本発明の実施態様を、図面にもとづいて詳細に説明する。
図１は、エレベータ装置を構成するゴンドラ（以下、単にエレベータと言う）Ａと、このエレベータの天井部ａに載設される空気調和機Ｓの斜視図である。
【００２０】
上記エレベータＡは、図の手前側である前面に開閉扉ｂが設けられ、内部に乗員が出入りできる。上記空気調和機Ｓとは別の天井部位にワイヤｃが接続され、エレベータＡはワイヤｃによって吊持される。
【００２１】
この上方部には巻き上げ機が配置され、一端にエレベータＡを吊持するワイヤａが巻き付けられる。また、ワイヤａの他端にはガイドレールに沿って移動するウエイトが取付けられ、エレベータとバランスをとって昇降駆動される。（以上、図示しない）
上記空気調和機Ｓは、図２ないし図４に示すように構成される。図２は空気調和機の内部を示す斜視図、図３は空気調和機の平面図、図４は空気調和機の断面図である。
【００２２】
空気調和機本体１は、長手（縦）方向と幅（横）方向および高さ方向ともに、矩形状に形成される筐体である。この本体１内の長手方向の中央部から側方へある程度ずれた位置には、幅方向に亘って仕切り板２（仕切り手段）が設けられ、内部を左右に二分している。仕切られた一方を室内側ユニット部３Ａと呼び、他方を室外側ユニット部３Ｂと呼ぶ。
【００２３】
はじめに、上記室内側ユニット部３Ａから詳述する。
本体底面板１ａの隅部に室内吸込み口４が設けられ、これとは幅方向に離間した位置に室内吹出し口５が設けられる。これら室内吸込み口４と室内吹出し口５と対向するエレベータＡの天井部ａには同一形状の開口部が設けられていて、室内側ユニット部３ＡとエレベータＡ内部とは互いに連通状態にある。
【００２４】
また、室内吸込み口４と室内吹出し口５との間で、かつ本体長手方向に亘って室内熱交換器６が配置される。この室内熱交換器６の下部にはドレンパンＰが配置されていて、室内熱交換器はドレンパン上に立位する。
【００２５】
なお、上記ドレンパンＰは室内熱交換器６の底面部全体を収容するとともに、上記仕切り板２の下端部に設けられる切欠部２ａを介して室外側ユニット部３Ｂへ延出され、このユニット部において後述するように構成される。
【００２６】
上記室内熱交換器６と本体側面板１ｂとの空間に、ファン７ｆの周面一部を上記室内吹出し口５に対向し、モータ７ｍの回転軸を室内熱交換器と対向させた室内送風機７が配置されている。このファン７ｆは、いわゆるシロッコファンと呼ばれていて、回転駆動することにより回転軸側から空気を吸込んで周面から吹出すようになっている。
【００２７】
なお、室内吸込み口４と長手方向に並んだ位置に圧縮機８が配置され、周囲は補助仕切り板９によって囲まれる。この補助仕切り板９を備えることによって、圧縮機８から室内吸込み口４と室内熱交換器６とに対する熱的影響が阻止され、かつ騒音の漏れが防止される。
【００２８】
つぎに、上記室外側ユニット部３Ｂについて詳述する。
空気調和機本体１の両側面板１ｂ，１ｃにそれぞれ外気吸込み口１０ａ，１０ｂ，１０ｃが設けられる。後述する理由から、一方の側面板１ｂに設けられる外気吸込み口１０ａは一ヶ所であるが、他方の側面板１ｃに設けられる外気吸込み口１０ｂ，１０ｃは二ヶ所となっている。
【００２９】
本体１の背面板１ｄには吹出し口１１が設けられる。図１に示すエレベータＡを基準にしてみると、この開閉扉ｂが設けられる面と空気調和機本体１の同一面に背面板１ｄが設けられ、吹出し口１１が開口する。なお、エレベータＡに対する本体の配置方向は図１に限定されるものではなく、エレベータの設計事情に応じて適宜変更可能である。
【００３０】
本体１内において、本体背面板１ｄと所定の空間を存して長手方向のほぼ中央部に、背面板１ｄとほぼ平行な幅方向に亘って室外熱交換器１２が配置される。この室外熱交換器１２は、多数枚のフィンを互いに所定の間隙を存して並置し、これらフィンに熱交換パイプを貫通させた、いわゆるフィンドチューブタイプの熱交換器である。
【００３１】
ここでは、前後２列の熱交換器列１２Ａ，１２Ｂが並べられて室外熱交換器１２が構成される。各熱交換器列１２Ａ，１２Ｂの大部分は背面板１ｄと略平行に幅方向に亘って直状に形成され、互いに密に接触している。
【００３２】
そして、各熱交換器列１２Ａ，１２Ｂの一方端側には所定の曲率で曲成される曲成部１２Ａ_１，１２Ｂ_１と、側面板１ｃに沿う直状の延設部１２Ａ_２，１２Ｂ_２がそれぞれ連設される。各熱交換器列１２Ａ，１２Ｂの曲成部１２Ａ_１，１２Ｂ_１の曲成方向は互いに反対方向であり、延設部１２Ａ_２，１２Ｂ_２の延出方向も互いに反対方向である。
【００３３】
したがって、前列の熱交換器列１２Ａは前面側に曲成してから側面板１ｃに沿って前面側へ延出され、後列の熱交換器列１２Ｂは背面側に曲成してから側面板１ｂに沿って背面側へ延出される。そして、各延設部１２Ａ_２，１２Ｂ_２が沿う側面板１ｂの対向部位に、合計二ヶ所の上記外気吸込み口１０ｂ，１０ｃが設けられている。
【００３４】
各熱交換器列１２Ａ，１２Ｂの他方端側は直状のままで終わっているところから、この端部と対向する側面板１ｂには一ヶ所の外気吸込み口１０ａしか設けられていない。当然、一方端側のように曲成部と延設部とを連設してもよく、この場合は側面板に二ヶ所の外気吸込み口を設けることになる。
【００３５】
本体１内における室外熱交換器１２と背面板１ｄとの空間には、室外送風機１３が配置される。この室外送風機１３は、回転軸を背面板１ｄに対向させたファンモータ１３ｍと、このファンモータの回転軸に嵌着されるいわゆるプロペラ型のファン１３ｆからなる。
【００３６】
室外送風機１３のファン１３ｆと対向する本体背面板１ｄには上記吹出し口１１が設けられる。したがって、室外送風機１３を駆動することにより、各側面板１ｂ，１ｃの外気吸込み口１０ａ，１０ｂ，１０ｃから室外側ユニット部３Ｂに外気が吸込まれ室外熱交換器１２に導かれる。そして、室外熱交換器１２から室外送風機１３を介して背面板１ｄの吹出し口１１から外部へ吹出されるようになっている。
【００３７】
上記室外送風機１３とは室外熱交換器１２を介して反対側の部位に、掻き上げ部材（掻き上げ手段）１５が室外熱交換器１２と対向して配置される。この掻き上げ部材１５は、室外送風機１３のファンモータ１３ｍよりも小型のモータ１６と、このモータの回転軸に嵌着され周縁に図示しない掻き上げ部を備えた回転板１７とからなる。
【００３８】
上記室内側ユニット部３Ａに配置されるドレンパンＰは、仕切り板２を介して室外側ユニット部３Ｂへ延出され、上記掻き上げ部材１５の回転板１７一部を囲む補助ドレンパンＰａと連通している。
【００３９】
そして、回転板１７の周縁一部が補助ドレンパンＰａに集溜するドレン水に浸漬するよう設計されている。すなわち、回転板１７が回転駆動されることによって、この周縁の掻き上げ部が順次ドレン水中に浸漬し、かつ回転にともなって図３および図４で示す一点鎖線Ｅａである遠心方向にドレン水を掻き上げるようになっている。
【００４０】
特に図３で示すように、掻き上げ部材１５の位置基準は、回転板１７の遠心方向Ｅａが前側の熱交換器列１２Ａで、かつこの曲成部１２Ａ_１に対向するように設定されている。
【００４１】
回転板１７が掻き上げるドレン水は、当然、側面板１ｂ方向へも飛散するが、ここにはストッパ兼ガイド板１９が配置されていて、ドレン水を受け止めて外気吸込み口１０ａから外部へドレン水が飛び出すのを防止し、かつ吸込まれる外気を案内するようになっている。
【００４２】
特に図４に示すように、空気調和機本体１の天板１ｅは室内側ユニット部３Ａで高く、室外側ユニット部３Ｂでそれよりも低い。しかも、室外側ユニット部３Ｂにおいて室外熱交換器１２と仕切り板２との間の部位、すなわち掻き上げ部材１５と対向する上方部位は、仕切り板２側から室外熱交換器１２側へかけて下方に傾斜する傾斜部１ｅ_１となっている。
【００４３】
傾斜部１ｅ_１の下方には、所定間隔を存して並行に、図５にも示すような案内部材１８が取付けられる。この案内部材１８の一側端は仕切り板２とは離間し、他側端は室外熱交換器１２の上端部に接触している。回転板１７の遠心方向と対向する部位には開口部１８ａが設けられていて、回転板が掻き上げたドレン水が通過して天板傾斜部１ｅ_１に付着し易いように配慮されている。
【００４４】
このようにして構成される空気調和機であり、冷房運転を指示することにより、室内送風機７が駆動されてエレベータＡ内の空気が室内吸込み口４から本体１の室内側ユニット部３Ａに吸込まれ、室内熱交換器６に導かれて熱交換をなし、冷気に変わって室内吹出し口５から吹出される。このようにしてエレベータＡ内に冷気が供給され、室内の冷房をなす。
【００４５】
暖房運転を指示することにより、室内送風機７が駆動されてエレベータＡ内の空気が室内吸込み口４から本体の室内側ユニット部３Ａに吸込まれ、室内熱交換器６に導かれて熱交換をなし、暖気に変わって室内吹出し口５から吹出される。このようにしてエレベータＡ内に暖気が供給され、室内の暖房をなす。
【００４６】
冷暖房いずれの運転においても、室外側ユニット部３Ｂにおいては、室外送風機１３が駆動され、両側面板１ｂ，１ｃの外気吸込み口１０ａ，１０ｂ，１０ｃから外気が室外側ユニット部に吸込まれ、室外熱交換器１２に導かれて熱交換をなし、背面板１ｄの吹出し口１１から外部へ吹出される。
【００４７】
上記掻き上げ部材１５は、冷房運転時に作用する。すなわち、室内熱交換器６と熱交換した空気に含まれる水分が凝縮してドレン水に変りドレンパンＰに流下する。このドレン水は室外側ユニット部３Ｂへ流れて、掻き上げ部材１５の回転板１７周縁一部を浸漬する。
【００４８】
回転板１７は回転駆動され、ドレン水を遠心方向Ｅａへ掻き上げるので、ドレン水は水滴もしくは霧状になって同方向に飛散する。一方で室外送風機１３が駆動されて外気吸込み口１０ａ，１０ｂ，１０ｃから室外熱交換器１２へ外気を導くので、水滴もしくは霧状のドレン水が外気に混合して室外熱交換器１２に降りかかる。
【００４９】
冷房時には室外熱交換器１２で冷媒を凝縮して凝縮熱を放出するので、降りかかったドレン水は凝縮熱を吸収して早急に蒸発する。したがって、ドレン水は早急に蒸発処理され、かつ室外熱交換器１２は熱交換効率が向上する。
【００５０】
この空気調和機においては、室外送風機１３を背面側に配置し、風下側である吸込み側に室外熱交換器１２を配置したから、室外熱交換器の表面に風圧がかからずにすみ、スムーズな風の流れを得られ、風切り音に発生が少ない。
【００５１】
掻き上げ部材１５を室外熱交換器１２の風上側で、吸込まれる外気の案内路中に位置するようにしたから、風の流れが均一となって掻き上げたドレン水を均等に飛散させられる。そして、室外熱交換器１２へ効率よく降りかけられ、これにより室外熱交換器の熱交換効率をさらに高めることができ、ドレン水の蒸発処理をより確実に行える。
【００５２】
従来のような室外送風機を室外熱交換器の風上側に配置して室外熱交換器に向けて送風する構成に比べて、空気の流れが静かであるため運転音とドレン水掻き上げ音が小さくなり、空気調和機の近傍にいても運転音が気にならない。
【００５３】
上記室外熱交換器１２は、いわゆるフィンドチューブタイプの熱交換器であり、その一方端に曲成部１２Ａ_１と側面板１ｃに沿う直状の延設部１２Ａ_２を連設し、この延設部に対向して外気吸込み口１０ｂを備えたから、掻き上げたドレン水が側面板１ｃ方向へ飛散しても熱交換器フィンに直接当たり、外気吸込み口１０ｂから外部へ出ることを防止でき、熱交換効率が向上する。
【００５４】
ここでは、室外熱交換器１２は前後２列の熱交換器列１２Ａ，１２Ｂを並べ、各列の一方端側に曲成部１２Ａ_１，１２Ｂ_１と延設部１２Ａ_２，１２Ｂ_２とを連設し、それぞれの延設部に対向する側面に外気吸込み口１０ｂ，１０ｃを備えたから、さらに室外熱交換器１２の熱交換効率の向上を得られ、かつ筐体である空気調和機本体１のコンパクト化を図れる。
【００５５】
掻き上げ部材１５を構成する回転板１７の遠心方向Ｅａを室外熱交換器１２の曲成部１２Ａ_１に対向するよう配置したから、回転板によるドレン水の飛散方向と室外熱交換器を構成するフィンの面方向とが相違し、飛散したドレン水がフィン面で止められて、外気吸込み口１０ｂへの漏れを防止する。
【００５６】
本体天板１ｅに傾斜部１ｅ_１を備え、掻き上げられて付着するドレン水を流下させ室外熱交換器１２上面に落下案内するから、ドレン水の蒸発作用を促進でき、さらに室外熱交換器の熱交換効率が向上する。
【００５７】
上記天板傾斜部１ｅ_１に案内部材１８を備えて、途中落下するドレン水を受けて室外熱交換器１２上面に導くようにしたから、さらにドレン水蒸発作用を促進でき、熱交換効率を高められる。
【００５８】
エレベータＡの天井部ａに室内側ユニット部３Ａと室外側ユニット部３Ｂとに仕切られた空気調和機本体１を配置したから、エレベータＡ内の搭乗者から空気調和機本体１までの距離が非常に近い条件で運転騒音を小さく抑えられ、騒音による快適性を損なわずに空調された室内空間を得ることができる。
【００６０】
【発明の効果】
以上説明したように本発明によれば、一体形でドレン水を室外熱交換器へ飛散させて蒸発処理する空気調和機であり、風切り音等の騒音の低減を得るとともに、ドレン水蒸発処理の効率向上化を得るなどの効果を奏する。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a treatment structure for drain water generated during cooling operation in a so-called integrated air conditioner in which an indoor heat exchanger and an outdoor heat exchanger are accommodated in a main body.
[0002]
[Prior art]
For example, an air conditioner that cools or heats the interior of an elevator is mounted on a gondola (hereinafter simply referred to as an elevator) that constitutes the elevator apparatus. As this air conditioner, a so-called integrated type using a refrigeration cycle and having an indoor heat exchanger and an outdoor heat exchanger in the main body is used.
[0003]
During the cooling operation, the dew point of the air that is heat-exchanged by the indoor heat exchanger is lowered, moisture is condensed, and it is dripped as drain water. A drain pan is disposed at the lower part of the indoor heat exchanger, and all drain water is collected. This drain water is guided to the outdoor heat exchanger side and scraped up. By spraying water on this heat exchanger, the heat exchange efficiency is improved and the drain water is evaporated.
[0004]
Specifically, a slinger ring is attached to the outer periphery of the fan of the outdoor blower, and a part thereof is immersed in drain water. When the outdoor blower is driven to rotate, the fan blows outside air to the outdoor heat exchanger, and the ring scoops up the drain water. The drain water drops into water, mixes with the outside air, and falls onto the outdoor heat exchanger.
[0005]
Alternatively, there is a case where a dedicated scraping member is provided in parallel with a normal type outdoor blower. This is provided with a scraping portion along the periphery of the rotating plate connected to the motor, and the rotating plate is rotationally driven to scrape water in the centrifugal direction. At the same time, the drainage water blown up by the outdoor blower is put on the wind and sent to the outdoor heat exchanger.

By the way, both the outdoor fan with a slinger ring and a normal type outdoor fan and a scraping member are arranged on the windward side of the outdoor heat exchanger to blow outside air to the outdoor heat exchanger. There is no change in attaching.
[0007]
However, the outdoor heat exchanger has a structure in which a large number of fins are arranged with a narrow gap therebetween, and resistance is generated by blowing strong air from outside. In addition, there was unevenness such that the wind strongly hits the blower facing surface of the outdoor heat exchanger and the peripheral part weakened, causing wind noise and water drainage noise, which caused noise.
[0008]
In order to reduce these noises, an outdoor blower is arranged on the leeward side of the outdoor heat exchanger, the outside air sucked into the main body is directly guided to the outdoor heat exchanger, and then discharged to the outside through this blower. Good.
[0009]
However, considering the evaporation of drain water, the outdoor heat exchanger is located on the suction side of the outdoor blower and does not exist on the outlet side. Without draining to the heat exchanger, everything is discharged to the outside and drain water evaporation treatment becomes impossible.
[0010]
The present invention has been made in consideration of the above-mentioned circumstances, and the object of the present invention is an integrated type in which an indoor heat exchanger and an outdoor heat exchanger are accommodated in the main body, and indoor heat exchange.

For reasons to be described later, the outside air suction port 10a provided in one side plate 1b is provided in one place, but the outside air suction ports 10b and 10c provided in the other side plate 1c are provided in two places.
[0029]
A blowout port 11 is provided on the back plate 1 d of the main body 1. When the elevator A shown in FIG. 1 is taken as a reference, a back plate 1d is provided on the same surface of the air conditioner main body 1 as the surface on which the door b is provided, and the outlet 11 is opened. In addition, the arrangement | positioning direction of the main body with respect to the elevator A is not limited to FIG. 1, It can change suitably according to the design situation of an elevator.
[0030]
In the main body 1, an outdoor heat exchanger 12 is disposed in a substantially central portion in the longitudinal direction with a predetermined space with the main body back plate 1 d over a width direction substantially parallel to the back plate 1 d. The outdoor heat exchanger 12 is a so-called finned tube type heat exchanger in which a large number of fins are juxtaposed with each other with a predetermined gap therebetween and a heat exchange pipe is passed through the fins.
[0031]
Here, the outdoor heat exchanger 12 is configured by arranging two heat exchanger rows 12A and 12B in the front and rear rows. Most of each of the heat exchanger rows 12A, 12B is formed in a straight shape over the width direction substantially parallel to the back plate 1d, and is in close contact with each other.
[0032]
Each heat exchanger column 12A, the curved portion _12A 1, 12B ₁ is at one end of the 12B that is bent at a predetermined curvature, the straight extending portions _12A 2 along the side plate 1c, 12B ₂ Are connected to each other. The bending directions of the bent portions 12A ₁ and 12B ₁ of the heat exchanger rows 12A and 12B are opposite to each other, and the extending directions of the extending portions 12A ₂ and 12B ₂ are also opposite to each other.
[0033]
Therefore, the front heat exchanger row 12A is bent to the front side and then extended to the front side along the side plate 1c, and the rear heat exchanger row 12B is bent to the rear side and then the side plate 1b. Is extended to the back side. Then, the opposing part of the extending portion _12A 2, 12B ₂ extend along a side plate 1b, total two places of the outside air inlet 10b, 10c are provided.
[0034]
Since the other end side of each heat exchanger row 12A, 12B ends in a straight shape, the side plate 1b facing this end is provided with only one external air inlet 10a. Naturally, the bent portion and the extended portion may be provided continuously on one end side. In this case, two side air inlets are provided on the side plate.
[0035]
An outdoor fan 13 is disposed in the space between the outdoor heat exchanger 12 and the back plate 1d in the main body 1. The outdoor blower 13 includes a fan motor 13m having a rotation shaft opposed to the back plate 1d, and a so-called propeller type fan 13f fitted on the rotation shaft of the fan motor.
[0036]
The outlet 11 is provided in the main body back plate 1d facing the fan 13f of the outdoor blower 13. Therefore, by driving the outdoor blower 13, the outside air is sucked into the outdoor unit 3B from the outside air inlets 10a, 10b, 10c of the side plates 1b, 1c, and led to the outdoor heat exchanger 12. And it blows off from the blower outlet 11 of the backplate 1d through the outdoor air blower 13 from the outdoor heat exchanger 12.
[0037]
A scraping member (scraping means) 15 is disposed opposite to the outdoor heat exchanger 12 at a site opposite to the outdoor fan 13 via the outdoor heat exchanger 12. The scraping member 15 includes a motor 16 that is smaller than the fan motor 13m of the outdoor blower 13 and a rotating plate 17 that is fitted to the rotating shaft of the motor and includes a scraping portion (not shown) on the periphery.
[0038]
The drain pan P disposed in the indoor unit 3A extends to the outdoor unit 3B through the partition plate 2 and communicates with the auxiliary drain pan Pa surrounding a part of the rotary plate 17 of the scraping member 15. Yes.
[0039]
And it is designed so that a part of peripheral edge of the rotating plate 17 may be immersed in the drain water collected in the auxiliary drain pan Pa. That is, when the rotating plate 17 is driven to rotate, the scraping portion at the periphery is sequentially immersed in the drain water, and the drain water is supplied in the centrifugal direction, which is the one-dot chain line Ea shown in FIGS. It is going to be scraped up.
[0040]
As shown particularly in Figure 3, the position reference of the scraping up member 15, a centrifugal direction Ea of the rotating plate 17 is set as the front side of the heat exchanger column 12A, and facing the curved portion 12A ₁ .
[0041]
The drain water that is swung up by the rotary plate 17 naturally also scatters in the direction of the side plate 1b. However, a stopper / guide plate 19 is disposed here, and the drain water is received from the outside air inlet 10a by receiving the drain water. Is prevented from jumping out, and the outside air to be sucked is guided.
[0042]
In particular, as shown in FIG. 4, the top plate 1e of the air conditioner body 1 is higher in the indoor unit 3A and lower in the outdoor unit 3B. Moreover, in the outdoor unit 3B , the portion between the outdoor heat exchanger 12 and the partition plate 2, that is, the upper portion facing the scraping member 15 is downward from the partition plate 2 side to the outdoor heat exchanger 12 side. It becomes the inclined part 1e ₁ which inclines to.
[0043]
Below the inclined portion 1e ₁ , a guide member 18 as shown in FIG. 5 is attached in parallel with a predetermined interval. One end of the guide member 18 is separated from the partition plate 2, and the other end is in contact with the upper end of the outdoor heat exchanger 12. The portion facing the centrifugal direction of the rotating plate 17 have openings 18a is provided, the drain water rotating plate is raised scraped is considered so easily attached to the top plate inclined portion 1e ₁ through.
[0044]
The air conditioner is configured as described above, and when the cooling operation is instructed, the indoor blower 7 is driven and the air in the elevator A is sucked into the indoor unit 3A of the main body 1 from the indoor suction port 4. Then, the heat is guided to the indoor heat exchanger 6 to be exchanged, and the air is changed into cold air and blown out from the indoor outlet 5. In this way, cool air is supplied into the elevator A to cool the room.
[0045]
By instructing the heating operation, the indoor blower 7 is driven and the air in the elevator A is sucked into the indoor unit 3A of the main body from the indoor suction port 4 and led to the indoor heat exchanger 6 for heat exchange. Then, it changes into warm air and is blown out from the indoor outlet 5. In this way, warm air is supplied into the elevator A to heat the room.
[0046]
In both the cooling and heating operations, the outdoor blower 13 is driven in the outdoor unit 3B, and the outdoor air is sucked into the outdoor unit through the outdoor air inlets 10a, 10b, and 10c of the side plates 1b and 1c, and the outdoor heat exchange is performed. The heat is exchanged by being guided to the vessel 12 and blown out from the blow-out port 11 of the back plate 1d.
[0047]
The scraping member 15 acts during cooling operation. That is, the moisture contained in the air exchanged with the indoor heat exchanger 6 is condensed and turned into drain water and flows down to the drain pan P. This drain water flows into the outdoor unit 3B and immerses a part of the periphery of the rotary plate 17 of the scraping member 15.
[0048]
The rotary plate 17 is driven to rotate and scoops up the drain water in the centrifugal direction Ea, so that the drain water becomes water droplets or mist and scatters in the same direction. On the other hand, since the outdoor blower 13 is driven and the outside air is guided from the outside air inlets 10a, 10b, and 10c to the outdoor heat exchanger 12, water droplets or mist-like drain water is mixed with the outside air and falls onto the outdoor heat exchanger 12.
[0049]
During cooling, the outdoor heat exchanger 12 condenses the refrigerant and releases the condensation heat, so that the drained water that has fallen absorbs the condensation heat and evaporates quickly. Therefore, the drain water is immediately evaporated and the outdoor heat exchanger 12 is improved in heat exchange efficiency.
[0050]
In this air conditioner, the outdoor blower 13 is arranged on the back side, and the outdoor heat exchanger 12 is arranged on the suction side, which is the leeward side, so that the wind pressure is not applied to the surface of the outdoor heat exchanger, and smooth. Wind flow can be obtained and wind noise is low.
[0051]
Since the scraping member 15 is positioned on the windward side of the outdoor heat exchanger 12 in the guide path of the sucked outside air, the wind flow becomes uniform and the drained water that has been scraped can be evenly scattered. . Then, the outdoor heat exchanger 12 can be efficiently lowered, thereby further improving the heat exchange efficiency of the outdoor heat exchanger, and the drain water can be more reliably evaporated.
[0052]
Compared to the conventional configuration where an outdoor blower is arranged on the windward side of the outdoor heat exchanger and blows air toward the outdoor heat exchanger, the air flow is quieter, so the operation noise and drain water pick-up sound are reduced. Even if it is in the vicinity of an air conditioner, I do not mind the driving sound.
[0053]
The outdoor heat exchanger 12 is a heat exchanger of the so-called finned tube type, continuously provided a straight extending portions 12A ₂ along the curved portion 12A ₁ and the side plate 1c on one end, this extended Since the outside air suction port 10b is provided opposite to the portion, even if the drained water is scattered in the direction of the side plate 1c, it can directly contact the heat exchanger fins and can be prevented from coming out from the outside air suction port 10b. Exchange efficiency is improved.
[0054]
Here, the outdoor heat exchanger 12 has two rows of front and rear heat exchanger rows 12A and 12B, and the bent portions 12A ₁ and 12B ₁ and the extending portions 12A ₂ and 12B ₂ are connected to one end side of each row. Since the outside air inlets 10b and 10c are provided on the side surfaces facing the respective extending portions, the heat exchange efficiency of the outdoor heat exchanger 12 can be further improved, and the air conditioner main body 1 which is the casing can be obtained. Can be made compact.
[0055]
Because was arranged to face the centrifugal direction Ea of the rotating plate 17 constituting the scraping up member 15 to the curved portion 12A ₁ of the outdoor heat exchanger 12, constituting the scattering direction of the drain water due to the rotation plate outdoor heat exchanger The surface direction of the fin is different, and the scattered drain water is stopped by the fin surface, thereby preventing leakage to the outside air inlet 10b.
[0056]
Since the main body top plate 1e is provided with the inclined portion 1e ₁ and drained water that has been scraped up is flowed down and guided to fall on the upper surface of the outdoor heat exchanger 12, the drain water evaporating action can be promoted, and the outdoor heat exchanger Heat exchange efficiency is improved.
[0057]
Since the top plate inclined portion 1e ₁ is provided with the guide member 18 so as to receive the drain water falling on the way and guide it to the upper surface of the outdoor heat exchanger 12, the drain water evaporation action can be further promoted and the heat exchange efficiency is increased. It is done.
[0058]
Since the air conditioner main body 1 partitioned into the indoor unit 3A and the outdoor unit 3B is arranged on the ceiling part a of the elevator A, the distance from the passenger in the elevator A to the air conditioner main body 1 is very large. The driving noise can be kept small under conditions close to, and an air-conditioned indoor space can be obtained without impairing comfort due to noise.
[0060]
【The invention's effect】
As described above, according to the present invention, it is an air conditioner that integrally evaporates drain water to the outdoor heat exchanger and evaporates, thereby reducing noise such as wind noise and the like. There are effects such as improving efficiency.
