Abstract

A chlorinator system for pools or spas is disclosed. The chlorinator system includes a replaceable chlorinator cell cartridge having built in sensors, switches, and custom connections. The chlorinator system includes a controller, a chlorinator, a replaceable cell cartridge, and compression fittings for connecting the chlorinator to piping of a pool or spa system. The cartridge includes a body, a bi-directional flow switch, a connector plug, a lid, a printed circuit board, which includes non-volatile memory, and electrically-charged plates or blades.

First claim

What is claimed is:

1. A replaceable cartridge for a chlorinator, comprising:
a cartridge body removable from the chlorinator, the cartridge body having a plurality of electrically-charged plates; and
a printed circuit board positioned in said cartridge body and in electrical communication with said electrically-charged plates, said printed circuit board including a memory for storing information relating to operation of the replaceable cartridge;
wherein said cartridge body houses said memory, said printed circuit board, and said electrically-charged plates;
wherein said cartridge body, said memory, said printed circuit board and said electrically-charged plates form a single unit removable from the chlorinator; and
wherein said electrically-charged plates and said cartridge body of said single unit are positioned along a first axis defining a fluid flow path such that fluid enters, exits and flows through said electrically-charged plates and said cartridge body of said single unit along the first axis, the first axis being transverse to a second axis along which the single unit is removable from the chlorinator.

2. The replaceable cartridge of claim 1 , wherein said printed circuit board includes a microprocessor in electrical communication with said memory.

3. The replaceable cartridge of claim 2 , further comprising a cartridge cap connected to said cartridge body, said cartridge cap including said printed circuit board.

4. The replaceable cartridge of claim 3 , further comprising a cartridge cover connected to said cartridge cap, said cartridge cover including a locking key and an electrical connector in communication with said printed circuit board.

5. The replaceable cartridge of claim 4 , further comprising at least one sensor connected to said printed circuit board, said at least one sensor sensing a parameter relating to the operation of the replaceable cartridge.

6. The replaceable cartridge of claim 5 , further comprising a bi-directional paddle and a reed switch in electrical communication with said printed circuit board, said bi-directional paddle in communication with said reed switch to detect fluid flow through the replaceable cartridge.

7. The replaceable cartridge of claim 6 , further comprising a ferromagnetic slug and a centering magnet having magnetic attraction to said slug, such that in the absence of fluid flow through the replaceable cartridge, said slug is attracted to said centering magnet.

8. The replaceable cartridge of claim 7 , wherein when fluid flows through the replaceable cartridge, the magnetic attraction between said slug and said centering magnet is broken.

9. The replaceable cartridge of claim 8 , wherein said reed switch is a hall effect sensor.

10. The replaceable cartridge of claim 8 , wherein the cartridge cap includes a plug in communication with said cartridge cover and said printed circuit board.

11. A replaceable cartridge for a chlorinator, comprising:
a replaceable chlorinator cartridge removably positionable within a chlorinator body;
said replaceable chlorinator cartridge including a cartridge body, a cartridge cap, a plurality of electrolytic plates and at least one circuit element in electrical communication with said plurality of electrolytic plates;
said replaceable chlorinator cartridge housing said plurality of electrolytic plates and said at least one circuit element;
said cartridge cap housing said at least one circuit element and said cartridge body housing said plurality of electrolytic plates;
said replaceable chlorinator cartridge, said plurality of electrolytic plates and said at least one circuit element forming a single unit removable from said chlorinator body; and
said plurality of electrolytic plates and said replaceable chlorinator cartridge of said single unit are positioned along a first axis defining a fluid flow path such that fluid enters, exits, and flows through said plurality of electrolytic plates and said replaceable chlorinator cartridge of said single unit along the first axis, the first axis being transverse to a second axis along which the single unit is removable from the chlorinator body.

12. The replaceable cartridge of claim 11 , further comprising a printed circuit board and a microprocessor in electrical communication with a memory.

13. The replaceable cartridge of claim 12 , further comprising a cartridge cover connected to said cartridge cap, said cartridge cover including a locking key and an electrical connector in communication with said printed circuit board.

14. The replaceable cartridge of claim 13 , further comprising at least one sensor connected to said printed circuit board, said at least one sensor sensing a parameter relating to the operation of the replaceable cartridge.

15. The replaceable cartridge of claim 14 , further comprising a bi-directional paddle and a reed switch in electrical communication with said printed circuit board, said bi-directional paddle in communication with said reed switch to detect fluid flow through the replaceable cartridge.

16. The replaceable cartridge of claim 15 , further comprising a ferromagnetic slug and a centering magnet having magnetic attraction to said slug, such that in the absence of fluid flow through the replaceable cartridge, said slug is attracted to said centering magnet.

17. The replaceable cartridge of claim 16 , wherein when fluid flows through the replaceable cartridge, the magnetic attraction between said slug and said centering magnet is broken.

18. The replaceable cartridge of claim 17 , wherein said reed switch is a hall effect sensor.

19. The replaceable cartridge of claim 18 , wherein the cartridge cap includes a plug in communication with said cartridge cover and said printed circuit board.
