PHOTOCATALYST DEODORIZER

Object of this invention is to provide a photocatalyst deodorizer wherein it is possible to extend the life and increasing an efficiency of filters, and it is possible to activate a photocatalyst which a deodorizing filter carries, by optimizing the positional relation between a tubular light source for emitting light to activatee a photocatalyst and a deodorizing filter, and an emission angle of the tubular light source. Further a photocatalyst deodorizer of this invention makes it easy to maintenance and replacement of filters and the tubular light source. [0002] A photocatalyst deodorizer comprising an air purifying portion which is removably arranged in an air passage and constructed from a dust collecting filter, a deodorizing filter carrying a photocatalyst, and a tubular light source arranged in that order in a stack, or constructed from said dust collecting filter, said tubular light source and said deodorizing filter arranged in that order in a stack; wherein said tubular light source is arranged at a position which obtains total surface irradiation of one side of said deodorizing filter, and set at an emission angle which obtains total surface irradiation.
