<p>PROBLEM TO BE SOLVED: To provide an air conditioner improved in the operability on the occasion of installation by making a drain cap easy to extract and insert and also improved in the heat insulation of the peripheral edge of a drain port. SOLUTION: The drain cap 9 is constituted of a base part 9a, an insertion part 9b provided upright from the base part, having a plurality of ring-shaped projecting parts 9b' for sealing on the outer peripheral surface and inserted into the drain port 6a to stop water and a heat-insulating covering part 9c covering the outer periphery of the drain port and insulating heat. Therefore the drain cap is easily fitted to and removed from the drain port and the operability is improved, while the efficiency of heat insulation is enhanced and also the effect of energy saving can be expected.</p> |
