PROBLEM TO BE SOLVED: To provide a cabin deodorization device capable of deodorizing gradually according of intensity of an odor in the cabin, and introducing fresh air into the cabin for ventilation according to degree of deodorization in consideration of an atmospheric component in outside of the vehicle.SOLUTION: An on-vehicle CPU 5 controls a ventilation operation part 8 or a window opening/closing operation part 9 according to degree of deodorization in cabin performed by a deodorization device 7, thereby introduces fresh air into the cabin. When it is determined that a fresh air component of a specific kinds is contained in the fresh air by a predetermined value or more by an odor detection part 4, the ventilation operation part 8 and the window opening/closing operation part 9 are controlled so as not to introduce the fresh air into the cabin, and deodorization performed by the deodorization device 7 is performed continuously.COPYRIGHT: (C)2015,JPO&INPIT【課題】車内の臭いの強さに応じて段階的に消臭し、車外の大気成分を考慮しながら消臭の度合いに応じて車内に外気を導入して換気することができる車内消臭装置を提供する。【解決手段】車載CPU5が、消臭器7による車内の消臭度合いに応じて換気操作部8または窓開閉操作部9を制御して車内に外気を導入し、臭い検出部4によって特定の種類の外気成分が外気中に所定の値以上含まれていると判別された場合は、換気操作部8および窓開閉操作部9を制御して車内に外気を導入せずに、消臭器7による消臭を継続する。【選択図】図1
