Abstract

A water treatment system includes an ozone generator combined with an electrolytic chlorine generator in a compact, efficient and serviceable assembly. The system may include a modular and replaceable ozone generator, which allows a damaged or non-functional ozone generator to be quickly and efficiently replaced. In order to protect the ozone generator from damage, a fail-safe drain valve assembly may also be provided which will expel backflowing pool water before it is allowed to backflow into the ozone generator. The water treatment system may further include an insulated electrolytic chlorine generator that mitigates or eliminates current leakage for efficient operation.

First claim

What is claimed is:

1. A water treatment system configured for use with a pool, the water treatment system comprising:
an electrolytic chlorine generator;
an ozone generator; and
a treatment assembly including a tube-shaped tank, comprising:
a first fluid passageway including the electrolytic chlorine generator;
a second fluid passageway including a venturi structure with a suction inlet configured to receive ozone gas from the ozone generator;
a fluid inlet in communication with the first and second fluid passageways; and
a fluid outlet in communication with the first and second fluid passageways.

2. The water treatment system of claim 1 , further comprising a mixing chamber positioned downstream of the electrolytic chlorine generator and the ozone generator and positioned upstream of the fluid outlet.

3. The water treatment system of claim 1 , wherein the first fluid passageway includes a flow rate monitor configured to activate the electrolytic chlorine generator with a sufficient fluid flow through the first fluid passageway and deactivate the electrolytic chlorine generator with an insufficient fluid flow through the first fluid passageway.

4. The water treatment system of claim 3 , further comprising a switch operatively coupled to a pivot flapper disposed along the first fluid passageway to monitor a flow rate within the first fluid passageway.

5. The water treatment system of claim 4 , wherein with a sufficient flow of fluid through the first passageway the switch activates the electrolytic chlorine generator.

6. The water treatment system of claim 5 , wherein the pivot flapper pivots toward the switch to cause the switch to activate the electrolytic chlorine generator.

7. The water treatment system of claim 6 , wherein with an insufficient flow of fluid through the first passageway, the pivot flapper is unable to pivot toward the switch, so the electrolytic chlorine generator is deactivated.

8. The water treatment system of claim 1 , wherein the first fluid passageway includes a flow restrictor configured to divert flow to the second fluid passageway.

9. The water treatment system of claim 8 , wherein the flow restrictor is disposed at an upstream end of the first fluid passageway relative to the electrolytic chlorine generator.

10. The water treatment system of claim 9 , wherein the flow restrictor comprises:
a valve body with an inlet end and an outlet end;
a base disposed at the outlet end of the valve body;
a fluid outlet formed between the base and the valve body;
a valve disposed within the valve body and cooperating with the valve body to selectively permit or restrict flow through the valve; and
a spring operatively coupled to the valve to bias the valve towards a closed position relative to the valve body.

11. The water treatment system of claim 10 , wherein the valve includes a longitudinal connecting portion having an end cap at an upstream end, and the flow restrictor further includes a limit block having an inner diameter smaller than that of the valve body, with a valve seat formed as a stepped-down portion of the limit block and configured to interact with the end cap of the valve body to regulate fluid flow through the valve.

12. The water treatment system of claim 1 , further comprising a housing that supports the electrolytic chlorine generator and the ozone generator, wherein the ozone generator is removably coupled to the housing.

13. The water treatment system of claim 1 , wherein the electrolytic chlorine generator includes electrode plates.

14. The water treatment system of claim 13 , wherein the electrode plates are titanium electrode plates.

15. The water treatment system of claim 14 , further comprising a retainer disposed within the first fluid passageway, the retainer retaining the titanium electrode plates and having a plurality of apertures to allow fluid contact with the titanium electrode plates.

16. The water treatment system of claim 1 , wherein the electrolytic chlorine generator and the venturi structure are combined into a single unit.

17. A water treatment system configured for use with a pool, the water treatment system comprising:
a housing defining a chamber, the chamber having a fluid inlet and a fluid outlet;
a fluid flow monitor disposed within the housing along a first direction relative to the fluid inlet; and
a treatment electrode disposed along the first direction relative to the fluid flow monitor, wherein the fluid flow monitor comprises a pivot flapper positioned proximate the fluid inlet and distal the fluid outlet.

18. The water treatment system of claim 17 , wherein a fluid passes from the fluid inlet to the fluid outlet along the first direction.

19. The water treatment system of claim 17 , wherein the pivot flapper includes a pivot configuration wherein the pivot flapper pivots toward the fluid flow monitor in response to a sufficient fluid flow through the first fluid passageway, and a rest configuration wherein the pivot flapper pivots away from the fluid flow monitor in response to an insufficient fluid flow through the first fluid passageway.

20. The water treatment system of claim 19 , wherein, in the pivot configuration, the treatment electrode is activated, and wherein, in the rest configuration, the treatment electrode is deactivated.
