向上が課題とされている。[0006] However, in order to increase the sterilizing power of ultraviolet rays, the bactericidal effect is greatly affected by the illuminance of ultraviolet rays and the time of irradiating the fluid with ultraviolet rays, which determine the sterilizing effect. Adopting high-power UV lamps and securing long UV irradiation time are difficult to achieve due to structural limitations and high costs of using the purifier in a narrow bathroom, and a filter tank to increase the purification capacity is difficult. Increasing the amount of the filter material is difficult to realize due to problems such as propagation of various bacteria and an increase in the size of the apparatus, and improvement of the sterilization / purification ability by photocatalysis as a remaining means is an issue.
