摘要： PROBLEM TO BE SOLVED: To effectively prevent damage to a drain pipe in case of urging a drain hose into an end of the pipe by projecting a plurality of ribs from a root of the pipe in a draining mechanism for an air conditioner having the drain hose urged to the end of the pipe formed integrally with a drain pan to be connected. SOLUTION: At the time of operating to cool, a drain condensed on a surface of a heat exchanger is drained through a drain pan 6a, a drain pipe 12 and a drain hose 13. In this case, a plurality of ribs 15 are projected from an outer periphery of an upper part of a root of the pipe 12. These ribs 15 are extended along an axial direction, connected at their inner ends to an outer surface of a rear wall of the pan 6a and extended at their outer ends until they are brought into contact with an end of a connector 14 at the time of urging the connector 14 into the pipe 12. Thus, in the case of urging the connector 14 into the end of the pipe 12, the pipe 12 can be prevented from being damaged. And, since a clamping margin of the connector 14 can be increased by decreasing an inner diameter of the connector 14, it can prevent the drain from being leaked from a gap between the pipe 12 and the connector 14.

摘要： PROBLEM TO BE SOLVED: To eliminate a peak of noise generated from the vicinity of a stabilizer of a crossflow fan by setting heights of the stabilizer uneven in an indoor unit for an air conditioner for cooling or heating the indoor air through a heat exchanger and then diffusing the air from an air outlet via the fan. SOLUTION: A crossflow fan 7, three fin and tube type heat exchangers 5a, two drain pans 6a and the like are contained in a body of a wall hanging type indoor unit. Stabilizers 20 are integrally formed with rear ends of the pans 6a. In this case, the each stabilizer 20 is formed to have two types of heights (h) and h1 by forming cutouts 21 apart at a predetermined interval along a lengthwise direction at an upper edge of the stabilizer 20. Thus, the heights of the stabilizer 20 are set uneven. Hence, generation of noise of a specific frequency from the vicinity of the stabilizer 20 is prevented to eliminate a peak of the noise.
