Abstract

PROBLEM TO BE SOLVED: To obtain the effects of heat insulation after doing away with a heat insulating material to be stuck onto the drip sink part of an air conditioner, by constructing the drip sink part main body out of the upper part of the drip sink and a nozzle inner wall member, and by forming a closed space part by the upper part of the drip sink and the nozzle inner wall member. SOLUTION: A drip sink part main body 10 is located downwards of a heat exchanger 6, and forms the top surface of a nozzle 2. The drip sink part 10c collects the dew water of the heat exchanger 6. A nozzle inner wall member 10d forms the top surface inside part of a blow-off nozzle. The closed space 12 inside the drip sink part is formed by the upper part 10c of the drip sink and the nozzle inner wall member 10d, and the space, in which the nozzle inner wall member 10d is fixed to the upper part 10c of the drip sink by a screw 13, is formed. An inner drain pan 14 forms the nozzle inner wall member 10d. Even if dew is formed at the space part that is formed to discharge in the closed space 12 in the drip sink part, it is prevented from being discharged outside. Thereby, the effects of obtaining the heat insulating performance, which is higher than conventional models can be possessed.
