CONNECTING STRUCTURE FOR AIR CONDITIONING DUCT, AIR CONDITIONING DUCT AND AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To detachably attach an outlet duct or the like to an air conditioner such as a spot cooler simply and assuredly in a one-touch manner. SOLUTION: In a connecting structure, the annular connecting part 70 of an outlet unit 60 is provided with an insert pipe 72 inserted into the annular connecting part 80 of a housing 11, a pin member 73a for a lock mechanism and a protrusion 74a elastically moving forward and backward for a stopper mechanism. On the other hand, the connecting part 80 is provided with an L-shaped groove 83a into which the pin member 73a is inserted and a recess 84a corresponding to the protrusion 74a. Thus, when the connecting part 70 is rotated relative to the connecting part 80, the lock mechanism operates to prevent the separation of them. Further, the stopper mechanism operates so that they cannot rotate. Accordingly, the outlet unit 60 can be assuredly attached to the housing 11 in a one-touch operation.
