なお、ドレン水の水量は多くないため、保水した水分は自然蒸発により乾燥し、運転を繰り返した場合でも継続して保水することが可能である。   Since the amount of drain water is not large, the retained water can be dried by natural evaporation and continuously retained even when the operation is repeated.

実施の形態３．
図６は本発明の実施の形態３における空気調和機の室外機の要部である下面側に水密性膜を有する多孔質発泡材を示す斜視図、図７はその下面側に水密性膜を有する多孔質発泡材の断面図であり、それ以外の室外機本体部の構成は前述の実施の形態１のものと同様である。したがって、ここでも説明にあたっては前述の図１乃至図４を参照するものとする。 Embodiment 3 FIG.
6 is a perspective view showing a porous foam material having a water-tight film on the lower surface side, which is a main part of the outdoor unit of the air conditioner according to Embodiment 3 of the present invention, and FIG. 7 shows a water-tight film on the lower surface side. It is sectional drawing of the porous foam material which has, and the structure of the other outdoor unit main-body part is the same as that of the above-mentioned Embodiment 1. FIG. Therefore, in this description as well, the above-described FIGS. 1 to 4 are referred to.

本実施の形態の空気調和機の室外機は、前述の実施の形態１のものにおける樹脂製の皿状ドレン受け１３の代わりに下面側に水密性の膜１７を有する多孔質の発泡材１６を用い、この下面側に水密性の膜１７を有する多孔質の発泡材１６を、機械室９における少なくとも銅管４の下方のベース１上、つまり機械室９におけるベース１上で圧縮機２が設置された部分を除く部位に着脱自在に設けたものである。   The outdoor unit of the air conditioner of the present embodiment has a porous foam material 16 having a watertight film 17 on the lower surface side instead of the resin-made dish-shaped drain receiver 13 in the first embodiment. The porous foam material 16 having a watertight film 17 on the lower surface side is used, and the compressor 2 is installed on the base 1 at least below the copper tube 4 in the machine room 9, that is, on the base 1 in the machine room 9. It is provided so as to be detachable at a portion other than the portion that is made.

本実施の形態の空気調和機の室外機において、運転中に低温の冷媒が流れる部分の銅管４には、空気中の水分が結露し、滴下する。   In the outdoor unit of the air conditioner of the present embodiment, moisture in the air is condensed and dripped onto the copper pipe 4 where the low-temperature refrigerant flows during operation.

この滴下水には銅イオンが含まれているため、異種金属に接触した場合に電気腐食が発生するが、本実施の形態のように、銅管４の下方に、下面側に水密性の膜１７を有する多孔質の発泡材１６を設け、この下面側に水密性の膜１７を有する多孔質の発泡材１６に銅管４から滴下する水分を吸収・保水させることで、金属製のベース１に直接銅イオンを含んだ水が落下することを防止することができ、電気腐食による金属製のベース１の腐食を未然に防止することができる。   Since this dripping water contains copper ions, electric corrosion occurs when it comes into contact with dissimilar metals. However, as in this embodiment, a water-tight film is formed below the copper tube 4 and on the lower surface side. The metal base 1 is provided by providing a porous foam material 16 having a watertightness 17 and absorbing and retaining water dripped from the copper tube 4 into the porous foam material 16 having a watertight film 17 on the lower surface side. It is possible to prevent water containing copper ions from falling directly on the metal base, and to prevent corrosion of the metal base 1 due to electric corrosion.

なお、ドレン水の水量は多くないが、滴下する銅管４の位置に集中してドレンが滴下するため、部分的に発泡材の下面まで水分が到達しベース１に接触する可能性がある。しかし、本実施の形態のように、下面側に水密性の膜１７を設けることによって、それよりも下方に漏れることなく、周囲の発泡材全体でドレンを吸収・保水することができる。   Although the amount of drain water is not large, the drain is concentrated at the position of the copper pipe 4 to be dripped, so that there is a possibility that water partially reaches the lower surface of the foam material and contacts the base 1. However, by providing the water-tight film 17 on the lower surface side as in the present embodiment, the drain can be absorbed and retained by the entire surrounding foam material without leaking downward.
