ULTRAVIOLET IRRADIATION DEVICE AND WATER DISCHARGE DEVICE
PROBLEM TO BE SOLVED: To provide an ultraviolet irradiation device suppressing generation of water scale on the surface of an irradiation window: and to provide a water discharge device.SOLUTION: An ultraviolet irradiation device includes: a flow passage having a flow passage body and a pair of water passage ports mounted on the flow passage body, making water supplied from one of the pair of water passage ports flow to the flow passage body and discharging the water through another of the pair of water passage ports; and a light-emitting part irradiating the water flowing through the flow passage body with ultraviolet rays via the ultraviolet irradiation window. The ultraviolet irradiation window includes a surface in contact with the water flowing through the flow passage body. The flow passage includes a water storage part storing the water so as to come in contact with the surface of the ultraviolet irradiation window while allowing air between the pair of water passage ports to flow in a state that water is not supplied.SELECTED DRAWING: Figure 3
【課題】照射窓表面における水垢の発生を抑制した紫外線照射装置及び吐水装置を提供する。【解決手段】流路本体と、流路本体に設けられた一対の通水口と、を有し、一対の通水口の一方から供給された水を流路本体に流し、一対の通水口の他方から排出する流路と、流路本体を流れる水に紫外線照射窓を介して紫外線を照射する発光部と、を備え、紫外線照射窓は、流路本体を流れる水に接する表面を有し、流路は、水の供給が無い状態において一対の通水口の間の空気の流れを可能にしつつ紫外線照射窓の表面と接するように水を溜める貯水部を有することを特徴とする紫外線照射装置が提供される。【選択図】図３
