Ultraviolet-based bathroom surface sanitization
A solution for cleaning and/or sterilizing one or more surfaces in a bathroom is provided. The sterilization can be performed using ultraviolet sources, which can emit ultraviolet radiation directed onto the surface(s). The cleaning can be performed using a fluid, such as water, that is flowed over the surface(s). The surface(s) can include at least a seat of a toilet and/or other surfaces associated with the toilet.
1. A system comprising:
means for detecting radiation from a seat of a toilet;
a first ultraviolet source configured to emit ultraviolet radiation at a first wavelength directed at the seat;
a second ultraviolet source configured to emit ultraviolet radiation at a second wavelength directed at the seat; and
a computer system for correlating the detected radiation with a presence of contamination on the seat and for operating at least one of: the first ultraviolet source or the second ultraviolet source, to sterilize the seat in response to the evaluating indicating the presence of contamination on the seat.
2. The system of claim 1 , wherein the first ultraviolet source operates in a UV-C wavelength range.
3. The system of claim 1 , wherein the second ultraviolet source emits ultraviolet radiation that excites a fluorescent signal from a target contaminant.
4. The system of claim 1 , wherein the first ultraviolet source operates for at most ten minutes and operates in a UV-C wavelength range, and wherein the second ultraviolet source emits blue-ultraviolet light.
5. The system of claim 1 , further comprising a set of fluid sources for cleaning the seat using a fluid.
6. The system of claim 5 , further comprising a fan for circulating air over the seat after the cleaning.
7. The system of claim 1 , wherein at least one of: the first ultraviolet source or the second ultraviolet source, emits ultraviolet radiation directed at a plurality of surfaces of the toilet.
8. The system of claim 1 , wherein the means for detecting includes a fluorescent sensor for detecting a fluorescent signal.
9. The system of claim 1 , wherein the means for detecting includes a visible light sensor for detecting visible light.
10. The system of claim 9 , further comprising a visible light source, wherein the computer system further operates the visible light source and the visible light sensor to acquire feedback to determine an effectiveness of the sterilization.
11. A system comprising:
a toilet including a seat;
means for detecting radiation from the seat of the toilet;
a first ultraviolet source configured to emit ultraviolet radiation at a first wavelength directed at the seat;
a second ultraviolet source configured to emit ultraviolet radiation at a second wavelength directed at the seat, wherein at least one of: the first ultraviolet source or the second ultraviolet source, is isolated from an area for the seat by an ultraviolet transparent material; and
a computer system for correlating the detected radiation with a presence of contamination on the seat and for operating at least one of: the first ultraviolet source or the second ultraviolet source, to sterilize the seat in response to the evaluating indicating the presence of contamination on the seat.
12. The system of claim 11 , wherein the ultraviolet transparent material comprises fluoropolymer.
13. The system of claim 11 , wherein the toilet further includes a cover for removably covering the seat, wherein at least one of: the first ultraviolet source or the second ultraviolet source, is located in the cover.
14. The system of claim 13 , wherein the cover includes means for maintaining a target spacing between the cover and the seat.
15. The system of claim 11 , wherein the first ultraviolet source operates in a UV-C wavelength range, and wherein the second ultraviolet source emits blue-ultraviolet light.
16. The system of claim 15 , wherein the seat includes a photocatalyst.
17. A bathroom including:
a set of fixtures;
means for detecting radiation from a surface of at least one of the set of fixtures;
a first ultraviolet source configured to emit ultraviolet radiation at a first wavelength directed at the surface of the at least one of the set of fixtures;
a second ultraviolet source configured to emit ultraviolet radiation at a second wavelength directed at the surface of the at least one of the set of fixtures; and
a computer system for correlating the detected radiation with a presence of contamination on the surface of the at least one of the set of fixtures and for operating at least one of: the first ultraviolet source or the second ultraviolet source, to sterilize the surface of the at least one of the set of fixtures in response to the evaluating indicating the presence of contamination on the surface of the at least one of the set of fixtures.
18. The bathroom of claim 17 , wherein the at least one of the set of fixtures includes one of: a toilet or a bidet.
19. The system of claim 17 , wherein at least one of the first ultraviolet source or the second ultraviolet source, is mounted above the set of fixtures.
20. The system of claim 19 , wherein the at least one of the first ultraviolet source or the second ultraviolet source mounted above the set of fixtures, emits a focused beam of ultraviolet radiation capable of being directed to a plurality of surfaces of at least one of the set of fixtures.
