MECHANISM FOR KILLING WOOD-ROTTING FUNGUS BY ULTRAVIOLET RAY IN UNDERFLOOR SPACE

摘要

PROBLEM TO BE SOLVED: To provide a nonchemical sterilization mechanism which can surely prevent wood, arranged in an underfloor space, from being rotted by all kinds of decay fungi, without use of any harmful chemicals.;SOLUTION: Ultraviolet rays are emitted from an ultraviolet radiation light source which is installed in an underfloor required location, and irregularly reflected from a reflecting material which is arranged on a space constituting surface surrounding the underfloor space, so as to be applied throughout the inside of the space. Thus, spores of the wood-rotting fungi are killed.;COPYRIGHT: (C)2010,JPO&INPIT
