<p>PROBLEM TO BE SOLVED: To provide a toilet bowl arrangement capable of irradiating a washing nozzle with ultraviolet ray in a wide range using one or a few ultraviolet ray LEDs.SOLUTION: The toilet bowl arrangement includes: a washing nozzle 2; an ultraviolet ray LED that emits an ultraviolet ray; and an ultraviolet ray diffusion part 4 that diffuses the ultraviolet ray emitted from the ultraviolet ray LED to irradiate the surface of the washing nozzle 2. The ultraviolet ray diffusion part includes: a light guide part that has an incident part allowing the ultraviolet ray to enter therein and a diffusion part for diffusing the entered ultraviolet ray. With this, the ultraviolet ray is diffused in a wide range to effectively sterilize the surface of the washing nozzle 2.</p> |
