Description

【0001】
【発明の属する技術分野】
本発明は,樹脂成形された2種類の支持部材によりエアーフィルタを支持するようにした壁埋込型空気調和機のエアーフィルタ支持装置に関する。
【0002】
【従来の技術】
空気調和機は,一般に圧縮機や室外熱交換器を備えた室外機と,該室外機からの冷媒が循環する室内熱交換器等を備えた室内機とにより構成されている。
【0003】
そして,室内機を壁に埋込んで配置する空気調和機の場合,室内機本体の前面に室内空気を取入れる吸気口を設け,この吸気口に対向するように室内熱交換機を配置している。
【0004】
室内機本体の筐体は,板金等で形成されて壁に形成された開口部の中に配設して,当該開口部全体を前面パネルによって塞いでいる。
【0005】
この前面パネルは,室内機本体とは別に形成され,また室内機本体の吸気口及び吐出口に対応する位置にそれぞれ吸気口と吐出口が設けられている。
【0006】
また前面パネルは,樹脂製や木製であり,外観が壁と調和できるような色や模様等が施されている。
【0007】
そして,室内機に吸気された室内の空気は,室内熱交換器と熱交換して再び室内に吹出されることにより,当該室内の空気調和が行われる。
【0008】
このとき,吸気した空気に含まれる埃等が室内熱交換器に付着すると,当該空気と冷媒との熱交換効率が低下するので,これを防止するために比較的大きい埃を除去するプレフィルタが室内熱交換器の風上側に設けられている。
【0009】
また,空気中の小さな埃や臭いを除去して空気の清浄化を行う目的から帯電フィルタと脱臭フィルタを備えた清浄化フィルタが設けられている。
【0010】
かかるプレフィルタ及び清浄化フィルタ等のエアーフィルタは,通常着脱を容易にするために室内熱交換器の幅寸法に対して略半分の寸法に形成されて,これらが幅方向に2枚並設されている。
【0011】
そして,各エアーフィルタの側端部は,複数の支持部材から構成されるエアーフィルタ支持装置により支持されて室内機の筺体に固定されている。
【0012】
【発明が解決しようとする課題】
しかしながら壁埋込型空気調和機の場合は,通常筐体自体が金属で形成されているため,上記支持部材も金属で形成されて筐体にネジ止め等して取付けられている。このため材料費がかさむと共に,取付施工が面倒となる問題があった。
【0013】
また,上述したように2枚のエアーフィルタを支持するには,支持部材が室内機の吸気口の右端,中央,左端に配置されるため,少なくとも3種類の支持部材が必要になり,これに伴い当該支持部材を形成するための金型も3種類必要になる。
【0014】
従って,少なくとも3回の金型成形行程を経なければならないため,工数が増え又コストアップする問題があり,加えて3種類の支持部材を識別して保管管理しなければならないため,在庫管理が面倒になる問題がある。
【0015】
そこで,本発明は,支持部材に低コストな材料を用いると共に工数の削減及び取付け施工を容易にした壁埋込型空気調和機のエアーフィルタ支持装置を提供することを目的とする。
【0016】
【課題を解決するための手段】

【0033】
以下の説明においては,右端部支持部材22と左端部支持部材21とは略同じ形状なので図3に示す左端部支持部材21を例に説明する。
【0034】
フィルタガイド30〜35は,清浄化フィルタ13を保持する清浄化フィルタガイド30,31,プレフィルタ12を保持するプレフィルタガイド32,33を主要構成としている。
【0035】
そして,清浄化フィルタガイド30と清浄化フィルタガイド31との間が清浄化フィルタ挿入溝38を形成し,またプレフィルタガイド32とプレフィルタガイド33との間がプレフィルタ挿入溝39を形成している。
【0036】
