To provide a vehicle air-conditioning duct that can solve the issue in a conventional air-conditioning duct in which fragrances or the like are contained in the outermost coating layer of the duct and the odor does not last long.SOLUTION: In a vehicle air conditioning duct 10 of the present invention, slits 34 formed in an inner layer portion 33 perform an opening and closing operation in accordance with the temperature of air-conditioning air. Then, since an intermediate layer portion 32 is exposed to an air channel 23 through an opening 36 of the opened slit 34, odor components contained in the intermediate layer portion 32 are released into the air channel 23. With this structure, odors in a vehicle cabin 21 are automatically adjusted during operation of an air-conditioning device 11 of a vehicle, thereby improving comfort of occupants. Further, when the air-conditioning device 11 is stopped, the slit 34 closes, whereby the odor components contained in the intermediate layer portion 32 are retained in the intermediate layer portion 32 over a long period.SELECTED DRAWING: Figure 2B
【課題】従来の空調ダクトは、芳香剤等がダクトの最表面の塗膜層に含有され、臭いが長続きしないという課題がある。【解決手段】本発明の車両用空調ダクト10では、内層部33に形成されるスリット34が、空調風の温度に応じて開閉動作する。そして、中間層部32が、開いたスリット34の開口部36を介して風路23に露出することで、中間層部32に含有される臭い成分が、風路23内へと放出される。この構造により、車室21内の臭いが、車両の空調装置11の稼働時において自動に調整されることで、乗員の快適性が向上される。また、空調装置11の停止時には、スリット34が閉じることで、中間層部32に含有される臭い成分が、長期間に渡り中間層部32内に保持される。【選択図】図2B
