【０００２】
【従来の技術】
一般に、圧縮機、室外熱交換器及び室外送風機等を、筐体内に収納した室外ユニットが知られている。この種のものでは、室外ユニットの運転中に外気温度を検出し、この外気温度に応じて、例えば、冷暖自動運転モードの切り換え制御を行ったり、除霜運転に入るタイミングを検知したりしている。この場合の外気温度検出センサは、室外熱交換器の外面に取り付けられるが、外気温度の検出精度を高めるためには、外気取り込み量の多い部分、すなわち風量の多い部分に取り付けることが望ましい。ところで、近年、室外ユニットの筐体の背側を開放し、この開放した背側に室外熱交換器を配置して、空気取り込み量を増大させたものが提案されている。このようなものでは、外気温度検出センサを室外熱交換器の風量の多い部分に取り付けるとなると、その取り付け手段としては、例えば、室外熱交換器のフィンの間を貫通させて、冷媒管に差し込んで取り付けなければならない（例えば、特許文献１参照）。

【０００９】
【発明の実施の形態】
以下、本発明の一実施形態について図面を参照して説明する。
【００１０】
図１及び図２において、１は室外ユニットを示す。この室外ユニット１は、図示を省略した室内ユニットに対し冷媒配管で接続され、これにより、分離型空気調和装置が構成されている。この室外ユニット１は、鋼板製の底板３の上に、同じく鋼板製の仕切り板５が立設されて、この仕切り板５の両側に、熱交換室Ａ及び機械室Ｂを備えて構成されている。
【００１１】
機械室Ｂには、冷凍サイクルの一部を構成する圧縮機７、アキュームレータ９、冷媒配管１１、さらには電装箱１３等が配置され、熱交換室Ａには、室外熱交換器１５、室外送風機１７等が配置されている。
【００１２】
熱交換室Ａ及び機械室Ｂは、両サイドが一対の鋼板製の側板２１で覆われ、底部が底板３で覆われ、上部が鋼板製の天板２３で覆われ、前部が同じく鋼板製の前板２５で覆われている。この前板２５と天板２３とは一体に成形されて、略Ｌ字状に形成されている。そして、熱交換室Ａ及び機械室Ｂの背側は開放され、この開放された背側には室外熱交換器１５が配置されている。これらが熱交換室Ａ及び機械室Ｂを囲う筐体を構成する。
【００１３】
上記構成では、室外熱交換器１５の上面に補強板３１が配置されている。この補強板３１は、熱交換室Ａ及び機械室Ｂのほぼ全幅に亘って設けられ、図３に示すように、室外熱交換器１５を挟み込む爪部３１Ａを備え、この爪部３１Ａ間（図５参照）に室外熱交換器１５の上部を挟み込んで取り付けられる。この補強板３１には、一対の側板２１と、天板２３と、室外送風機１７のモータ１７Ａを支持する支持プレート３３とが取り付けられている。
【００１４】
この支持プレート３３の上部３３Ａは、補強板３１側に折り曲げられ、そこには小さい開口３３Ｂが形成されている。そして、図４に示すように、この開口３３Ｂには、補強板３１に設けられた突起３１Ｂが嵌合し、これを嵌合した後、支持プレート３３の上部３３Ａと、補強板３１とが、ビス３７を介して結合される。また、図３に示すように、この支持プレート３３の下部３３Ｃは、上部３３Ａと反対側に折り曲げられ、この下部３３Ｃは、図示を省略したビスを介して、鋼板製の底板３に固定されている。
【００１５】
図５は、側板２１と補強板３１との結合手順を示す。この補強板３１の上面であって、当該補強板３１の背側の位置には、折り曲げにより上方に立ち上がる立ち上がり部３５が一体形成され、この立ち上がり部３５には、組み立て時に、天板２３を支持するための支持部３５Ａが一体形成されている。また、立ち上がり部３５の両端には、側板２１の錠状の折れ片２１Ａを引っ掛けて、当該側板２１を仮り止め可能にした係止部３５Ｂが形成されている。
【００１６】
つぎに、筐体の組み立て手順を説明する。
【００１７】
まず、底板３の上に、室外熱交換器１５を含む各種機器類を固定した後、この室外熱交換器１５の上部に、補強板３１をはめ込む。そして、この補強板３１に支持プレート３３を固定し、この支持プレート３３に室外送風機１７を取り付ける。ついで、補強板３１の係止部３５Ｂに、図６に示すように、セパレートされた一対の側板２１の折れ片２１Ａをそれぞれ引っ掛け、側板２１が倒れないように、一対の側板２１と補強板３１とを仮り止めする。
【００１８】
この仮り止めの状態で、図１を参照して、一体成形された前板２５と天板２３とを、一対の側板２１、及び補強板３１の支持部３５Ａの上に載せ、各板の姿勢を筐体形状に整えながら、必要箇所をビス止めする。補強板３１と側板２１とは、図５に示すように、ビス３７で本止めする。
【００１９】
本実施形態では、図７及び図８に示すように、補強板３１の立ち上がり部３５に凹部４１が形成され、この凹部４１に、外気温度検出用の温度センサを収容したセンサケース４３が取り付けられ、このセンサケース４３は、図９に示すように、その上に天板２３を被せて、この天板２３をビス（図示せず）で固定することにより、室外熱交換器１５の外面に固定されている。センサケース４３は、任意の位置に取り付け可能であり、例えば、側板２１からの距離Ｌ、又は熱交換器１５の上辺からの距離Ｈ等を変化させることができる。
【００２０】
このセンサケース４３は樹脂製であって、立ち上がり部３５の凹部４１への取り付け部４３Ａ（図８参照）と、室外熱交換器１５の外面に沿って垂下される籠状のセンサホルダ部４３Ｂとを備えて構成される。このセンサホルダ部４３Ｂは、図１０Ａ及び図１０Ｂに示すように、室外熱交換器１５の外面側が開放されて、この開放部には、温度センサ４５の脱着時に開閉される扉体４３Ｃが設けられている。この温度センサ４５はリード線４５Ａを含み、このリード線４５Ａはリード線押さえ４３Ｄに保持されて上方に延出し、取り付け部４３Ａの凹部４３Ｅ内に導かれた後、補強板３１に沿って配線されて、上記電装箱１３内の基板（図示せず）に接続されている。
【００２１】
この構成では、図９に示すように、補強板３１の長手方向の任意位置に凹部４１を形成することにより、その長手方向の任意位置にセンサケース４３を簡単に取り付けることができる。本来、センサケース４３は、外気取り込み量（風量）の多い位置に取り付けることが望ましい。機種によって、風量の多い位置が、変化するためである。
【００２２】
本実施形態では、風量の最も多い位置を選択し、その位置に合わせて、例えば、側板２１からの距離Ｌ、又は熱交換器１５の上辺からの距離Ｈを変化させて、センサケース４３を簡単に取り付けることができるため、高い精度で外気温度を検出することができる。また、籠状のセンサホルダ部４３Ｂに、温度センサ４５を収めたため、この温度センサ４５に直接手を触れることができず、その損傷を防止することができるし、空気の通りがよくなり、外気温度の正確な検出が可能になる。さらに、センサホルダ部４３Ｂには、扉体４３Ｃが開閉自在に設けられているため、この扉体４３Ｃを開くことにより、故障した温度センサ４５等を簡単に交換することができる。
【００２３】
この構成では、補強板３１を備えたことにより、セパレートされた側板２１の仮り止め、及び本止めがきわめて容易になる。また、補強板３１を備えたことにより、筐体の剛性を高めることができる。この構成では、室外ユニット１の横方向のサイズが変化した場合であっても、室外熱交換器１５、これに対応した補強板３１、底板３、前板２５、天板２３等の長さを変化させるだけでよく、一対の側板２１は、共通化することができる。
【００２４】
この構成では、室外熱交換器１５に対し、機器類等を直接取り付けることがなく、それらをすべて補強板３１に取り付けているため、室外熱交換器１５の薄いフィン等に損傷を与えることが少ない。
【００２５】
さらに、この筐体は、背側が開放されており、この開放された背側に、室外熱交換器１５が配置されるため、空気取り込み量が増大し、室外熱交換器１５の熱交換効率を向上させることができる。
【００２６】
以上、一実施形態に基づいて本発明を説明したが、本発明は、これに限定されるものではなく、種々変更が可能である。
【００２７】
【発明の効果】
本発明では、室外熱交換器における風量の多い任意の部分に、外気温度検出センサを簡単に取り付けることができる。

[0016]
Next, a procedure for assembling the casing will be described.
[0017]
First, after fixing various devices including the outdoor heat exchanger 15 on the bottom plate 3, the reinforcing plate 31 is fitted on the upper portion of the outdoor heat exchanger 15. Then, the support plate 33 is fixed to the reinforcing plate 31, and the outdoor fan 17 is attached to the support plate 33.

As shown in FIG. 5, the reinforcing plate 31 and the side plate 21 are permanently fixed with screws 37.
[0019]
In the present embodiment, as shown in FIGS. 7 and 8, a recess 41 is formed in the rising portion 35 of the reinforcing plate 31, and a sensor case 43 containing a temperature sensor for detecting the outside air temperature is attached to the recess 41. As shown in FIG. 9, the sensor case 43 is fixed to the outer surface of the outdoor heat exchanger 15 by covering the top plate 23 and fixing the top plate 23 with screws (not shown). Has been. The sensor case 43 can be attached at an arbitrary position, and for example, the distance L from the side plate 21 or the distance H from the upper side of the heat exchanger 15 can be changed.
[0020]
The sensor case 43 is made of resin, and includes a mounting portion 43A (see FIG. 8) of the rising portion 35 to the concave portion 41, and a bowl-shaped sensor holder portion 43B suspended along the outer surface of the outdoor heat exchanger 15.
