Abstract

Chlorinators with multiple spaced gas traps and flow sensors are detailed. The sensors also may be protected, at least somewhat, from contact with scale build ups by interposition of a mechanical barrier. Ramps or other geometric restrictions may be used to increase water flow to some or all of the gas traps. Additionally, the chlorinator housing may be configured so as to route, or focus, gases toward a small-sized, high point thereof.

First claim

What is claimed is:

1. A salt-water chlorinator comprising:
a. a housing defining a water inlet and a water outlet;
b. an electrolysis cell, at least a portion of which is positioned for use within the housing so an axis intersecting both the water inlet and the water outlet passes through the electrolysis cell;
c. a first gas trap comprising a first sensor positioned within the housing, wherein the first gas trap is positioned upstream of the electrolysis cell; and
d. a second gas trap (i) spaced from the first gas trap and (ii) comprising a second sensor positioned within the housing.

2. A salt-water chlorinator according to claim 1 in which the electrolysis cell comprises an electrode assembly, further comprising a barrier separating the first sensor from the electrode assembly.

3. A salt-water chlorinator according to claim 2 in which the barrier is formed as a scoop configured to channel water toward the first gas trap.

4. A salt-water chlorinator according to claim 2 in which the barrier is positioned between the water inlet and the electrode assembly.

5. A salt-water chlorinator according to claim 1 , further comprising a ramp configured to direct water toward the second gas trap.

6. A salt-water chlorinator according to claim 1 , further comprising means for indicating orientation of the housing.

7. A salt-water chlorinator according to claim 1 in which (a) the housing further defines an interior region forming a high point thereof and (b) the second gap trap is located at or adjacent the high point.

8. A salt-water chlorinator according to claim 1 , further comprising electronics configured to limit generated chlorine as a function of temperature.

9. A salt-water chlorinator according to claim 1 , further comprising electronics configured to prevent supply of electricity to the electrolysis cell unless both the first and second sensors sense water flow.

10. A salt-water chlorinator comprising:
a. a housing defining a water inlet and a water outlet;
b. an electrolysis cell comprising an electrode assembly, at least a portion of which is positioned for use within the housing so an axis intersecting both the water inlet and the water outlet passes through the electrolysis cell;
c. a first gas trap comprising a first flow sensor positioned within the housing, wherein the first gas trap is positioned upstream of the electrolysis cell;
d. a second gas trap (i) spaced from the first gas trap and (ii) comprising a second flow sensor positioned within the housing;
e. a barrier (i) separating the first sensor from the electrode assembly, (ii) positioned between the water inlet and the electrode assembly, and (iii) formed as a scoop configured to channel water toward the first gas trap;
f. a ramp configured to direct water toward the second gas trap; and
g. means for indicating orientation of the housing.

11. A salt-water chlorinator according to claim 2 , wherein the barrier is configured to channel water toward the first gas trap and wherein the barrier is positioned upstream of the electrode assembly so water contacts the first gas trap without encountering the electrolysis cell.
