Japanese Patent JPWO2023058376
Kind Code:
A1
Abstract:
With a fluid cleaning circulator having a hollow circular pipe in which a passage of a fluid is formed in a spiral shape, harmful microorganisms in the fluid are deactivated by ultraviolet light irradiation. Surface processing that reflects ultraviolet light is applied to an inner surface of the hollow circular pipe. A radiation prevention means that prevents radiation of an ultraviolet light from both ends of the hollow circular pipe to the outside is provided. An ultraviolet light LED element is provided on an inner wall of the hollow circular pipe only within a distance of approximately 1/2 of a flow passage length of the hollow circular pipe from a fluid inlet side end portion of a closed container of the hollow circular pipe.
