Abstract
Description
すなわち、本発明にの一態様に係る空気調和装置の室内機は、熱交換器から滴下する水を受ける流水路と、該流水路から導かれた水を受けるドレンパンと、を備えている空気調和装置の室内機であって、前記流水路は、長手方向の一方向に向かって全体が傾斜するとともに、該長手方向に直交する幅方向の一方向に向かって全体が傾斜する底面を有している。
図1には、空気調和装置の室内機1の外観が示されている。室内機1は、壁掛形とされており、上方から室内空気を吸い込み、下方から室内へと空調後の空気を吹き出す。室内機1は、図示しない室外機と接続されており、室外機にて圧縮された冷媒の供給を受け、室内機1の内部に設けられた室内熱交換器によって室内の空気を所定温度に調整する。
図5A及び図5Bに示されているように、室内熱交換器9の下面と設置面6との間には、インシュレータとして遮風部材8が設けられている。遮風部材8は、図2及び図3に示した設置面6の形状に略一致させた形状とされている。遮風部材8は、室内熱交換器9の下面と設置面6との間の隙間を埋める可撓性を有する部材であり、室内熱交換器9によって熱交換が行われないで隙間を通過する空気を極小化するために用いられる。
なお、図5において室内熱交換器9が2つ重ねて設けられているが、1つの熱交換器であっても良い。
室内熱交換器9で凝縮した水は流水路5へと導かれドレンパン7へと流れ込む。流水路5には、長手方向D1の一方向に向かって全体が傾斜するとともに、幅方向D2の一方向に向かって全体が傾斜する底面5aを有しているので、流水路5に流れ込んだ水は、長手方向D1に一方向に集められるとともに幅方向D2の一方向に集められる。このように、室内機1が傾斜されて取り付けられても、底面5aの全体が長手方向D1及び幅方向D2に傾斜されているので、底面5aの傾斜が常に維持されることになり、円滑に水をドレンパン7へと導くことができる。
