Benefits of technology

[0012]Another aspect of the present invention is a method of producing a cleaning effect in a toilet bowl including the steps of coating surfaces of toilet bowl where the cleaning effect is desired with a photocatalyst coating, providing a UV light source producing UV light having a wavelength of about 360-410 nm, and energizing the UV light source for a predetermined period of time to allow the UV light to react with the photocatalyst coating to produce a photocatalytic effect at the coated surface of the toilet to oxidize organic stain producing compounds.

Problems solved by technology

Because of its orientation, the toilet seat of the '543 patent does not appear to provide the necessary intensity into the bowl itself.
However, the location of the light is less than optimal for projecting energy onto the rim of the toilet bowl or into the bowl itself.
UV lights in the form or light bulbs are relatively expensive, use large amounts of energy, and require approximately 40-75 Watts of energy at 120 Volts.
As can be readily understood by those of skill in the art, the presence of such an energy source in close proximity to water, and particularly water that may be in very close proximity to an individual, is less than desirable.
Moreover, though the preceding described devices are directed to use of energy sufficient to kill microbes, such an energy output can have detrimental effects on users.
Indeed, UV light of sufficient energy to kill microbes can cause serious injury to humans.
For example, prolonged exposure can lead to sight issues, and more immediately even relatively short exposure to UV light in the 230-260 nm (nanometer) wavelength range is well known to cause serious burns to the skin of individuals.
Perhaps in view of these problems there has been relatively little large scale commercialization of UV light toilet seats.
Still further, even when used to good antimicrobial effect, the toilets on which such devices are mounted are not cleaned.
That is they are still susceptible to staining or being dirty, and in fact the killed microbes actually add to the problem.

Embodiment Construction

[0024]The present invention can be seen in FIGS. 1-3, wherein a toilet seat assembly 10 comprising a toilet seat 16 and lid 12 is depicted. In FIG. 1 the toilet seat assembly 10 is viewed from below and appears to comprise a normal toilet seat 16 and lid 12. In FIG. 2 a perspective view of the toilet seat assembly 10 is shown and again, from all outward appearances, the toilet seat assembly 10 appears normal.

[0025]FIG. 3 shows the toilet seat assembly 10 of the present invention in an open position. Mounted on the interior surface of the toilet lid 12 is a dome-shaped housing 14. The dome-shaped housing 14 includes a plurality of miniature UV lights, preferably light emitting diodes or LED's. The light emitting diodes emit UV light with a wavelength of approximately 360 nm, but in any event not more than 410 nm and preferably not less than 340 nm which, though known to be outside of the anti-microbial range, can create an effective cleaning action. The dome-shaped housing 14 is show...

Abstract

A device for cleaning a toilet bowl including a toilet seat assembly having a toilet lid and a toilet seat, a UV-light source producing UV-light of a wavelength of approximately 360 nm secured to an interior side of the toilet lid, a first switch for turning the UV light source on when the toilet lid is placed in a closed position, and a second switch for turning the UV light off upon expiration of a predetermined period of time.
