Document Type and Number:
WIPO Patent Application WO/2024/084797
Kind Code:
A1
Abstract:
Provided is a sink with a sterilization function that maintains the clean state of the sink and minimizes irradiation of ultraviolet light to the human body, and a method for sterilizing the sink. The sink is provided with a bowl, a faucet that discharges water into the bowl, a drain hole provided on the inner bottom surface of the bowl, an ultraviolet light source that emits ultraviolet light of which the main emission wavelength belongs to a wavelength band of 200 nm or more and less than 240 nm toward the inner surface of the bowl, a first detection unit that detects whether the bowl is in use, and a lighting control unit that controls the ultraviolet light source on the basis of the detection signal outputted from the first detection unit. When the first detection unit detects that the bowl is in use, the lighting control unit executes a sterilization mode in which ultraviolet light is irradiated toward the inner surface of the bowl.
