DETAILED DESCRIPTION
A chlorine generator system according to an illustrative embodiment is
shown in Fig. 1. The illustrative system includes an electrical controller 13 and a
chlorine generator 11 mounted in a bar top 12 of a spa 14. As may be appreciated,
the bar top 12 is an e of a user ible surface of the spa 14 where a user
may be, for example, a user or owner of the spa 14. In one embodiment, the spa 14
may be a portable spa.
The chlorine generator 11 comprises an electrode cartridge housing 15
and an electrode cartridge 17. In the rative embodiment, the electrode
cartridge 17 carries a pair of electrodes 53, 55, and is removably installed in the
electrode cartridge housing 15. In one embodiment, the housing 15 is keyed to the
electrode dge 17 to insure that the cartridge 17 may only be installed in the
housing 15 in a proper manner. In an illustrative embodiment, water from the spa
circulation path is routed up to the housing 15, through the electrodes 53, 55 and
back out of the housing 15 to the spa l4.
In an illustrative embodiment, the electrical controller 13 controls
generation of chlorine by the electrode cartridge 17. In one embodiment, the
electrical controller 13 is relatively small in size, powered through the spa control
system 16, and fully integrated into the spa 14. In one embodiment, the electrical
controller 13 utilizes an RS485 communication protocol to transmit data and
communicate with the spa control system 16. In one embodiment, the spa control
system 16 may be accessed through and driven by a spa l panel 18. In
another embodiment, a closed loop control system may be employed which includes
a sensor which es, for example, one or more of: chlorine, bromine, ozone,
ORP, pH, conductivity, alkalinity, cyanuric acid, water hardness and/or
temperature. The sensor then feeds parameters to an electronic ller which
then automatically causes generation of the riate amount of chlorine via the
chlorine generator ll.
In the illustrative embodiment, operation of the chlorine generator 11 is
controlled by user gs for chlorine output made at the spa control panel 18. In
an illustrative embodiment, the electrical controller 13 drives the electrodes of the
chlorine generator 11 in a constant current mode to enable an optimal or desired
chlorine generation rate. This mode of operation also allows the system to be
driven at different specific current levels to control the generation rate of chlorine
per hour depending on the user settings.
In one ment, the spa water is salted, for example, by adding
sodium chloride to achieve a concentration of, for example, 2000 ppm. Such an
ment may be characterized as a salt water chlorinator system.
2018/034957
As shown in Figs. 2—5, in an illustrative ment, the electrode
cartridge housing 15 comprises a wall fitting 19, which has ar groove 20,
which receives an edge, e.g. 101 (Fig. 1), of the spa bar top 12. The wall fitting 19
mounts to the bar top 12 via a centering ring 23 and a nut 25. A cap 27 is screwed to
the wall fitting 19 on the user side of the system to provide access to the electrode
cartridge 17. An al web portion 24 of the cap 27 also positions and holds the
electrode cartridge 17 in place during operation.
In an illustrative embodiment, an upper n 29 of a lower housing
n 22 glues into or otherwise attaches to the wall g 19 to form a watertight
attachment. An O-ring 3O mounts in a receptacle in the wall fitting 19 and provides
a watertight seal between the wall fitting 19 and the cap 27. In illustrative
ments, the wall fitting 19, cap 27, and lower housing section 22, may all be a
suitable molded plastic material, such as, for example PVC or ABS plastic. .
In the illustrative embodiment, the electrical connection of the electrode
cartridge 17 to the controller 13 via electrical leads 103, 105 (Fig. 1) is completed
through a pair of titanium electrical contacts 31, 33, which are molded into the
housing 15 in watertight fashion. The contacts 31, 33 have flat vertical terminals
34, 36 adjacent an inside surface of the housing 15, as well as quick disconnect
terminals 35, 37 on the outside of the housing 15. The electrical contacts 31, 33
thus enable dry electrical connections to the chlorine generator 11 and ease of
service of the system.
Below the electrical contacts 31, 33 is a drain port 41. This port 41 allows
for removal of any water that may have entered the dry n of the housing 15
during removal and replacement of the electrode cartridge 17. A water inlet port 43
2018/034957
on the bottom 45 of the housing 15 allows spa water to enter the housing 15 and
flow h the wet ode Chamber 47. At the top of the wet electrode
chamber 47 is an outlet port 49 through which the chlorinated spa water flows into
the spa 14. The vertical water flow through the housing 15 ensures efficient
flushing of the housing 15 and removal of all liquids and gases generated in the
housing 15 during operation of the nator 11.
As shown in Figs. 6—9, in an illustrative embodiment, the electrode
cartridge 17 comprises a tee handle 51 and pair of mixed metal oxide titanium
electrodes 53, 55. In illustrative embodiments, the electrodes 53, 55 may comprise,
for example, titanium or niobium base metal with a suitable oxide coating, such as,
for example, ruthenium oxide, iiidium oxide, or platinum oxide. In other
embodiments, the electrodes could be boron/nitrogen doped diamond.
In the illustrative embodiment, the electrodes 53, 55 are each formed as a
single piece and each includes a respective rectangular vertical portion 52, 54,
which forms into a respective horizontal base portion 56, 58, from which extends
respective outwardly curved spring arm ical contact 57, 59. The electrodes
53, 54 could of course be formed of multiple parts in other embodiments, for
example, with separate wet ode and spring contact components.
The horizontal base ns 56, 58 of each of the electrodes 53, 55 each
fit into a respective mating opening 67, 69 in an electrode cup 65 and are held in
place by a bottom surface 71 of the tee handle 51. An O—ring 63 provides a
watertight seal between the housing 15 and the ode cup 65.
First and second slots, 6. g. 99, are defined in the electrode cup 65 on
either side of horizontal projections 110, 111, through which a respective one of the
electrodes 53, 54 are inserted. Potting material is applied to seal gs around
the electrodes 53, 54. A cap 181 covers the opening in the electrode cup 65 and
prevents potting material from leaking up through the opening. In an illustrative
embodiment, the tee handle 51 and electrode cup 65 may be molded plastic
components formed, for example, of PVC or ABS plastic.
In an illustrative embodiment, the design and shape of the electrodes 53,
55 provide a single piece component extending from the wetted electrode blade
portions 52, 54 to the dry spring arm electrical contacts 57, 59. The wetted blade
portions 52, 54 of the electrodes 53, 55 are y spaced apart down the length of
the cartridge 17, and a spacer 61 is mounted at the end of the cartridge 17 to ensure
that the electrodes 53, 55 are held in proper position. The dry spring arm portions
57, 59 0f the electrodes 53, 55 form ical contact surfaces which are spring-
biased into electrical contact with the flat vertical electrical contact terminals 34, 36,
located on the interior of the electrode g 15.
As noted above, in one embodiment, the geometry of the electrode
cartridge 17 permits installation of the electrode cartridge 17 into the housing 15 in
only one ion and ation, insuring proper electrical contact. In particular,
in the illustrative embodiment, the outer vertical edges of the gular plastic
guards, 60, 62 around each of the electrode contact arms 57, 59 extend outwardly
and are shaped to mate with tive channels 74 defined by vertical guides 70,
72 formed on the inner wall of the electrode housing 19, as shown in Fig. 13. The
electrode cartridge 17 is thereby keyed to the housing 19, permitting the cartridge
17 to be inserted in only one orientation.
In one illustrative embodiment, a locking mechanism is used to secure the
cartridge 17 in place within the housing 15 independent of the cap 27. In particular,
as shown in Figs. 8 and 9, a spring loaded plunger is slidably d in an internal
opening in the tee handle 51 and ses a bottom shaft 75, a spring 77 and a
plunger cap 79. Respective locking bars 81, 83 with ball-shaped end surfaces 85,
87 are positioned to move laterally in respective ls 86, 88 (Fig. 10) formed in
the lower end of the tee handle 51. Oblong slots 88, 90 (Fig. 8) are formed in each
of the locking bars 81, 83 to permit the locking bars 81, 83 to move laterally left
and right with respect to the attachment screws 50, which attach the tee handle 51 to
the electrode cup 65.
As a result of this construction, the cartridge 17 cannot be installed in the
housing 15 without first pushing the plunger down by depressing the plunger cap 79
to retract the balls 85 87 to a position within the respective channels 86, 88 in the
lower end of the handle 51, as illustrated in Fig. 10. Once the balls 85, 87, are
positioned adjacent the channel 113 in the housing 15, as shown in Fig. 10, the
r can be pulled upward to the position shown in Fig.11 so as to force lateral
movement of the locking bars 81, 83, thereby g the balls 85, 87 to enter the
locking position shown in Fig. 1 1. If the dge 17 is not fully inserted into its
proper position in the housing 15, the dimensioning of the cap 27 will cause the cap
27 to push the cartridge 17 into the locked position of Fig. 11 when the cap 27 is
installed. If the cap 27 is thereafter removed, the cartridge 17 remains in its proper
place.
To remove the cartridge 17, the tee handle 51 may be grasped with two
fingers and the r cap 79 depressed with the thumb, thereby releasing the
WO 18067
locking balls 85, 87 and allowing them to slide back. The cartridge 17 may then be
lifted out of the housing 19.
Illustrative embodiments provide numerous advantages and improvements
and in particular a low cost, disposable, consumer replaceable electrode cartridge,
which is removable from the top side of a spa. Illustrative embodiments enable dry
removal of the electrode cartridge, avoiding the risk of electrical shock. Spa-side
control and operation of the system is also provided.
icantly lower water maintenance requirements are also achieved by
illustrative embodiments because the electrode cartridge is designed to last a short
life and to be disposable. Hence, the ity to control spa water ters in
order to maintain chlorine generator electrodes in operating condition is minimized
or eliminated. For example, softening the spa water can help to minimize the need
to clean the electrodes. The illustrative embodiments ate the need to clean
the electrodes and hence the need to control spa water parameters in order to
maintain the electrodes. Thus, when the electrode cartridge is spent (no longer
ing in spec) the system instructs the owner to change it out.
