Abstract

Cette invention se rapporte à un dispositif de désodorisation qui est capable de supprimer les odeurs et d'éliminer la maintenance en résolvant les problèmes notamment d'odeurs qu'un purificateur d'air traditionnel utilisant un photocatalyseur ne peut pas supprimer, sauf lorsqu'il utilise du charbon de bois activé, et qui ne peut pas éliminer la maintenance. Dans ce dispositif, un photocatalyseur (10) formé essentiellement de tourmaline pulvérisée est fixé sur la surface d'un passage d'écoulement d'air au niveau d'une partie spécifiée, par exemple sur un filtre à air (6), des sources lumineuses (7, 8) d'excitation du photocatalyseur sont placées à l'opposé de la partie fixe du photocatalyseur (10), un déshumidificateur (12) est placé sur le côté amont de la partie fixe du photocatalyseur (10), et des diodes électroluminescentes sont de préférence utilisées pour les sources lumineuses (7, 11) d'excitation du photocatalyseur (7, 11).
