Patent ID: 10206548

Abstract:
An antimicrobial toilet includes an inner surface of a toilet bowl which includes a non-doped titanium dioxide coating. The titanium dioxide coating is photocatalytic and antimicrobial in the presence of ultraviolet (UV) light. In the absence of UV light, the inner surface of the toilet bowl is not antimicrobial. The UV light source may be actuated after the waste has exited the toilet bowl. Consequently, the waste may be used in digesters used to produce clean energy or for analysis to assess the user's health status without being exposed to the antimicrobial properties of the titanium dioxide coating. The UV light may then be actuated to disinfect the toilet bowl. The outer shell of the toilet is coated with a doped titanium dioxide. The doped titanium dioxide is photocatalytic and antimicrobial in the presence of visible light. The outer shell is antimicrobial when standard room lights are actuated.
