Abstract

An electro-chlorinating device includes a housing and a pair of electrodes. The housing comprises a reservoir; an inlet port fluidly coupled to the reservoir; and a discharge device fluidly coupled to the reservoir. The discharge device is configured to be fluidly coupled to a plumbing product. The discharge device is configured to release a fluid from the reservoir into the plumbing product in response to a movement of water through the plumbing product. The pair of electrodes is coupled to the housing such that at least a portion of each electrode of the pair of electrodes is disposed within the reservoir.

First claim

What is claimed is:

1. An electro-chlorinating device, comprising:
a housing, comprising:
a reservoir;
an inlet port fluidly coupled to the reservoir;
a pair of electrodes coupled to the housing such that at least a portion of each electrode of the pair of electrodes is disposed within the reservoir; and
a discharge device fluidly coupled to the reservoir, the discharge device configured to be fluidly coupled to a flush tank, the discharge device configured to release a fluid surrounding the pair of electrodes into the flush tank toward a bottom of wall of the flush tank through a leg to a release port at an entrance to a flush valve of the flush tank in response to a movement of water through the flush valve of the flush tank, wherein the discharge device comprises at least one of a siphon or a venturi in response to the movement of water through the flush valve of the flush tank.

2. The electro-chlorinating device of claim 1 , wherein the reservoir is subdivided into a first portion and a second portion, wherein the first portion is fluidly coupled to the inlet port and the second portion is fluidly coupled to the first portion and the discharge device, and wherein the pair of electrodes are at least partially disposed within the second portion.

3. The electro-chlorinating device of claim 2 , wherein the first portion is a salt tank configured to receive a salt, and wherein the housing includes at least one of a permeable barrier or a weir that at least partially separates the first portion from the second portion.

4. The electro-chlorinating device of claim 2 , further comprising an exhaust port that fluidly couples the second portion with an environment surrounding the electro-chlorinating device.

5. The electro-chlorinating device of claim 1 , wherein the siphon comprises an inverted U-shaped channel, wherein the siphon is configured to be fluidly coupled to the flush tank of a toilet.

6. The electro-chlorinating device of claim 5 , wherein the inverted U-shaped channel comprises:
a first leg disposed in the reservoir and extending along a side of the housing toward a lower wall of the housing; and
wherein the leg is a second leg disposed on an outer surface of the housing and extending beyond the lower wall of the housing and toward a bottom wall of the flush tank, and
wherein the water leaving the siphon through the second leg draws the fluid up through the first leg and into the second leg, triggering a siphon effect.

7. The electro-chlorinating device of claim 5 , wherein the inverted U-shaped channel comprises a first leg fluidly coupled to the reservoir and a second leg fluidly coupled to the first leg,
wherein the electro-chlorinating device further comprises a check valve disposed at an intersection between the first leg and the second leg, and
wherein the check valve is configured to prevent air from being pulled into the siphon at beginning of a flushing event and to allow air to exit from the siphon during a period when the flush tank is being refilled.

8. The electro-chlorinating device of claim 5 , wherein the inverted U-shaped channel comprises:
a first leg fluidly coupled to the reservoir and extending upward from a lower wall of the housing; and
wherein the leg is a second leg extending downward from an upper portion of the first leg, and
wherein when the flush valve is activated, the water leaving the siphon through the second leg draws the fluid up through the first leg and into the second leg, triggering a siphon effect.

9. The electro-chlorinating device of claim 1 , wherein the discharge device comprises:
a chemical passage fluidly coupled to the siphon; and
the flush valve fluidly coupled to the chemical passage opposite the siphon, wherein the flush valve is configured to fluidly couple the flush tank of a toilet to a bowl of the toilet.

10. The electro-chlorinating device of claim 9 , wherein the chemical passage is fluidly coupled to an opening along a converging portion of the flush valve.

11. The electro-chlorinating device of claim 9 , wherein the chemical passage is fluidly coupled to an opening along a converging portion, having a decreasing cross-sectional area in a flow direction, of the flush valve,
wherein when the flush valve is activated, the water passing through the flush valve creates a venturi that pulls the fluid out of the reservoir through the siphon.

12. The electro-chlorinating device of claim 1 , further comprising an electrode cartridge comprising an access cap and a support member connected to the access cap, wherein the access cap is detachably coupled to the housing, and wherein the pair of electrodes is mounted to the support member.

13. The electro-chlorinating device of claim 1 , wherein the pair of electrodes comprises a first electrode and a second electrode oriented substantially parallel to the first electrode and spaced apart from the first electrode to form a gap, and wherein at least a portion of the pair of electrodes is positioned below a water-line of the reservoir.

14. A system, comprising:
a toilet comprising:
a bowl;
a flush tank that is fluidly coupled to the bowl;
a flush valve; and
an electro-chlorinating device, comprising:
a housing coupled to the flush tank and disposed at least partially within the flush tank, the housing comprising:
a reservoir spaced apart from the flush valve;
an inlet port fluidly coupled to the reservoir;
a pair of electrodes coupled to the housing such that at least a portion of each electrode of the pair of electrodes is disposed within the reservoir; and
a discharge device fluidly coupled to the reservoir and the flush tank, the discharge device configured to release a fluid surrounding the pair of electrodes into a bottom of the flush tank into a bottom of the flush tank through a leg to a release port at an entrance to the flush an entrance to the flush valve of the toilet in response to a movement of water through the flush valve of the toilet, wherein the discharge device comprises at least one of a siphon or a venturi in response to the movement of water through the flush valve of the flush tank.

15. The system of claim 14 , wherein the reservoir is subdivided into a first portion and a second portion, wherein the first portion is fluidly coupled to the inlet port and the second portion is fluidly coupled to the first portion and the discharge device, and wherein the pair of electrodes are at least partially disposed within the second portion.

16. The electro-chlorinating device of claim 15 , wherein the first portion is a salt tank configured to receive a salt, and wherein the housing includes at least one of a permeable barrier or a weir that at least partially separates the first portion from the second portion.

17. The system of claim 14 , wherein the siphon comprises an inverted U-shaped channel, wherein the siphon is fluidly coupled to the flush valve of the toilet that fluidly couples the flush tank to the bowl.

18. The system of claim 14 , wherein the electro-chlorinating device further comprises:
a chemical passage fluidly coupled to the siphon; and
the flush valve fluidly coupled to the chemical passage opposite the siphon, wherein the flush valve fluidly couples the flush tank to the bowl.

19. The system of claim 18 , wherein the chemical passage is fluidly coupled to an opening along a converging portion of the flush valve.

20. The electro-chlorinating device of claim 14 , further comprising an electrode cartridge comprising an access cap and a support member c
