図示は省略しているが、電装品122は、第1部材50及び第2部材60の正面側に配置されている。電装品122は、運転スイッチ、表示部、電磁波受信部、ブザーを含む。ユーザーは、運転スイッチを押すことで、空調室内機1の運転/停止を操作することが可能である。表示部は、空調室内機1の運転状態、タイマーの状態、フィルターの掃除の必要性、異常の発生、等を、光の点灯、点滅等で表示するものである。電磁波受信部は、リモートコントローラからの電磁波を受信する。電磁波は、赤外線である。ブザーは、ケーシング100の外部に露出しているものではないが、電装品122の一部である。電波受信部がリモートコントローラからの信号を受信すると、ブザーがその信号に応じた音を発する。図14に示すように、電装品122は、第2支持部124に取り付けられている。第2支持部124は、移動可能に第1支持部123に取り付けられている。
空調室内機1のメンテナンス時には、第1ドレンパン30aをケーシング100から取り外すことが好ましい。ここでは、第1ドレンパン30aを取り外す手順について説明する。
上記の通り、電装品122は、第2支持部124に取り付けられている。また上記の通り、第2支持部124は、第1部材50及び第2部材60の正面側に配置されている。このため、まずは第2支持部124を移動させる。第2支持部124は、図14から分かるように、ヒンジ構造で、第1支持部123に取り付けられている。第2支持部124は、ヒンジ部分の支柱124aを中心に回転することができる。第2支持部124を移動させることにより、第2支持部124は第1ドレンパン30aの取り外し経路外となり、第1部材50及び第2部材60が露出する。
第1ドレンパン30aをケーシング100から取り外すためには、ドレンホース40を第1ドレンパン30aから外す必要がある。上記の通り、第1端部41aが第1部材50及び第2部材60によって出口部31に接続されることにより、ドレンホース40は第1ドレンパン30aに接続している。
(3-1)、(3-2)で説明したように、第2支持部124を第1ドレンパン30aの取り外し経路外に移動させ、締結部材5を取り外すことにより、第1ドレンパン30aを取り外すことができる。第1ドレンパン30aは、前下の方向に引き出すことにより、ケーシング100から取り外すことができる。なお、第2部材60はドレンホース40に固定されたままで、第1ドレンパン30aをケーシング100から取り外すことができる。
(4-1)
壁掛け型の空調室内機は定期的にメンテナンスを実施する必要があり、メンテナンス時においてはドレンパンをケーシングから取り外すことが好ましい。また、メンテナンス時においては、ドレンホースをドレンパンから取り外すことが好ましい。このような場合に、ドレンホースとドレンパンとを壁掛け型の空調室内機に固定する締結部材が、壁掛け型の空調室内機の背面側から正面側に向かって締結されていると、メンテナンス性が低下する。
本開示における空調室内機1はケーシング100を備える。本開示における空調室内機1は、ケーシング100の正面板101、上面板102、下面板103、側面板104を取り外すことで締結作業が可能となる位置に、締結部材5が配置されている。このように、締結部材5へのアクセスを容易にすることで、空調室内機1はメンテナンス性が向上している。
出口部31を流れる結露水は低温である。このため、出口部31の外面において断熱性が確保されていなければ、出口部31の外面は結露するおそれがある。また、出口部31と第1部材50とを直接締結した場合、第1部材50が結露する恐れがある。
ドレンホース40は、結露水を対象空間SPの外部へと流すため、空調室内機1の正面側から見て後下の方向に延びるようにして、第1ドレンパン30aと接続する。第1部材50及び第2部材60は、この後下の方向に延びるドレンホース40に沿うようにして、本体部35や第1端部41aに固定される。このため、第1板状部50a及び第2板状部60aが第1隣接部50b及び第2隣接部60bに対して傾斜しない場合(第1板状部50a及び第2板状部60aが第1隣接部50b及び第2隣接部60bと同一平面状にある場合)、第1部材50及び第2部材60を締結部材5で締結する際に、締結部材5を前上の方向から締め込む必要が生じるため、メンテナンス性が低下する。
図3及び図15に示すように、本開示における締結部材5は、空調室内機1の正面側から見て、第1ドレンパン30aの下方空間に配置されている。このように、第1部材50と第2部材60との締結を第1ドレンパン30aの下方空間で行うことにより、本開示における空調室内機1はケーシング100の立体空間内の左右方向における省スペース化ができている。
上記の通り、第1部材50と第2部材60とは、締結部材5が第2貫通穴502と第3貫通穴601とを貫通することによって締結される。このとき、第1部材50が第1ドレンパン30aに固定され、第2部材60がドレンホース40に固定され、なおかつ第2貫通穴502の位置と第3貫通穴601の位置とが重ならない場合、ドレンホース40をねじる等の方法により、第2貫通穴502と第3貫通穴601との位置を調節する必要が生じる。このような方法により第2貫通穴502と第3貫通穴601との位置の調節が行われる場合、ドレンホース40の信頼性が低下するおそれがある。
(5-1)変形例A
上記実施形態においては、メンテナンス時において締結部材5の締め込み方向を水平方向に沿うように調節することを目的として、第1板状部50aが第1隣接部50bに対して傾斜し、かつ、第2板状部60aが第2隣接部60bに対して傾斜する例について説明した。しかしながら、本開示における第1板状部50a及び第2板状部60aの構成はこれに限られず、例えば、第1板状部50aが第1隣接部50bに対して傾斜し、第2板状部60aが第2隣接部60bに対して傾斜しないといった構成や、第1板状部50aが第1隣接部50bに対して傾斜せず、第2板状部60aが第2隣接部60bに対して傾斜するといった構成であってもよい。
