Title:
STERILIZER
Document Type and Number:
Japanese Patent JP2023006710
Kind Code:
A
Abstract:
To provide a sterilizer capable of sterilizing a fluid by effectively irradiating it with ultraviolet rays.SOLUTION: A sterilizer includes: a substantially spherical reservoir for containing a fluid; a supply port for supplying the fluid into the reservoir; an extraction port for taking out the fluid from the reservoir; and a light source for irradiating ultraviolet rays. The reservoir includes: a substantially hemispherical first reservoir positioned upstream in a flow direction of the fluid in the supply port;, and a substantially hemispherical second reservoir positioned downstream. When the supply port and the extraction port are projected onto a virtual plane perpendicular to an extending direction of the inner surface of a supply channel connected to the reservoir at the supply port, a center of gravity of the supply port and a center of gravity of the extraction port are separated. The light source is arranged such that its optical axis is at 75° to 105° with respect to a straight line connecting the center of gravity of the reservoir and the center of gravity of the extraction port.SELECTED DRAWING: Figure 4
