Abstract

The antimicrobial toilet includes one or more pairs of electrodes positioned below a water line when the hydraulic circuit is at equilibrium. The pairs of electrodes may be connected to a power source by electrical wires. In some embodiments, the electrodes are positioned on the inner wall of the toilet bowl and in some embodiments, the electrodes are positioned within the siphon tube. In some embodiments, the electrodes are metal strips and in others they are circular. When actuated, an electrical current passes through the toilet water between the electrode pairs resulting in disinfected water. Some embodiments include a pump and water conduit which transfers disinfected water to areas above the water line and emits the water to wash areas of the toilet.

First claim

We claim:

1. An antimicrobial toilet, comprising:
a hydraulic circuit comprising a siphon tube and a fresh water conduit, wherein the fresh water conduit is in fluid communication with the siphon tube and a source of fresh water;
a toilet bowl;
at least one pair of electrodes, wherein each of the at least one pair of electrodes comprises a cathode and an anode, and wherein each of the at least one pair of electrodes is positioned within the hydraulic circuit;
an electrical power source; and
at least two electrical lead wires, wherein each of the at least two electrical lead wires are in contact with either the anode or the cathode of each of the at least one pair of electrodes and with the electrical power source;
wherein at least one of the at least one pair of electrodes comprises two conductive rings disposed within the siphon tube.

2. The antimicrobial toilet of claim 1 , wherein the electrical power source comprises a battery.

3. The antimicrobial toilet of claim 1 , wherein the at least one pair of electrodes is positioned in a location that is submerged in water when the hydraulic circuit is at equilibrium.

4. The antimicrobial toilet of claim 1 , wherein the anode and the cathode in at least one of the at least one pair of electrodes are positioned at opposite sides of the toilet bowl.

5. The antimicrobial toilet of claim 1 , wherein at least one of the at least one pair of electrodes comprises two conductive metal strips.

6. The antimicrobial toilet of claim 5 , wherein the conductive metal strips are positioned within the toilet bowl.

7. The antimicrobial toilet of claim 5 , wherein the at least one pair of electrodes comprises a plurality of conductive metal strips.

8. The antimicrobial toilet of claim 1 , wherein the two conductive rings are positioned within a water seal within the siphon tube.

9. The antimicrobial toilet of claim 1 , wherein the at least one pair of electrodes comprises a plurality of pairs of electrodes, each of the plurality of pairs of electrodes comprising two conductive rings.

10. The antimicrobial toilet of claim 1 , wherein at least one of the at least one pair of electrodes is disposed within a groove, wherein the groove is disposed along the flush path.

11. The antimicrobial toilet of claim 1 , wherein the cathode comprises titanium metal and the anode comprises iridium oxide-coated titanium.

12. The antimicrobial toilet of claim 1 , wherein the pairs of electrodes are configured to perform one or both of the following chemical reactions in toilet water combined with urine:
2H 2 O+2Cl − (aq) H 2 (g)+Cl 2 (g)+2OH −
Cl 2 (aq)+H 2 O HClO (aq)+HCl (aq).

13. The antimicrobial toilet of claim 1 , wherein the at least one pair of electrodes and the at least two electrical lead wires are disposed within the fresh water conduit.

14. An antimicrobial toilet, comprising:
a hydraulic circuit comprising a siphon tube and a fresh water conduit, wherein the fresh water conduit is in fluid communication with the siphon tube and a source of fresh water;
a toilet bowl;
at least one pair of electrodes, wherein each of the at least one pair of electrodes comprises a cathode and an anode, and wherein each of the at least one pair of electrodes is positioned within the hydraulic circuit;
an electrical power source; and
at least two electrical lead wires, wherein each of the at least two electrical lead wires are in contact with either the anode or the cathode of each of the at least one pair of electrodes and with the electrical power source;
a pump;
a water circulation conduit; and
at least one dispenser, wherein the at least one dispenser is located above a level of water in the bowl when the hydraulic circuit is in equilibrium; and wherein the pump is configured to move electrolyzed water from the toilet bowl, through the water circulation conduit, and through the at least one dispenser back into the toilet bowl.

15. The antimicrobial toilet of claim 14 , wherein at least one of the at least one dispenser is in fluid communication with a bidet system.

16. The antimicrobial toilet of claim 14 , wherein at least one of the at least one dispenser is configured to direct electrolyzed water under a rim of the toilet bowl.

17. The antimicrobial toilet of claim 16 , wherein the at least one dispenser comprises a plurality of dispensers each configured to direct electrolyzed water under the rim of the toilet bowl.

18. The antimicrobial toilet of claim 14 , wherein at least one of the at least one dispenser is configured to direct electrolyzed water toward a wall of the toilet bowl.
