Abstract (en)
[origin: EP0331192A1] According to the present invention there is provided a toilet room deodorizing method wherein an offensive odor emitted from excrements in a toilet bowl is introduced directly into a deodorizing apparatus (1) at a predetermined air volume, then is mixed with a predetermined concentration of ozone and passed through a catalyst bed (8) for efficient deodorizing treatment, thereby preventing the offensive odor from being diffused into the toilet room and permitting this deodorizing treatment stably over a long period, as well as a toilet room deodorizing apparatus (1) wherein an ozone generator (5), a catalyst bed (8) and a fan (10) are provided within an air passage (4), whereby offensive odor components in a toilet bowl can be introduced for deodorization into the said air passage (4) within a predetermined time, and the entire apparatus can be constructed compactly and disposed in a toilet room without causing any inconvenience.
