Method and apparatus for operation of pool cleaner with integral chlorine generator
First Claim
1. An automated self-propelled pool cleaner having a housing, a pump for moving water through the housing, drive means for moving the pool cleaner over at least the bottom wall of a pool;
- an integral electrochemical chlorine generator positioned in said housing for producing bactericidal chlorine, the electrochemical chlorine generator comprising a plurality of negative and positive conductive plates arranged in a parallel spaced-part array to form a plurality of passageways, the array being positioned in the flow path of water moving through the housing;
an outlet for discharging water containing bactericidal chlorine produced by the electrochemical chlorine generator into the water proximate the exterior of the pool cleaner housing;
a source of electrical power operatively connected to the electrochemical chlorine generator; and
programmable control means for initiating and terminating the operation of the chlorine generator, the pump and the drive means, the control means programmed for;
a. activate the pump and the drive means to thereby move the pool cleaner across the surface of a wall of the pool to perform a programmed cleaning cycle;
b. initiate the operation of the electrochemical chlorine generator to thereby produce bactericidal chlorine from a chlorine-containing compound dissolved in the water during the cleaning cycle;
c. discharge bactericidal chlorine-containing water from the pool cleaner housing in a turbulent flow to mix with the water in the pool;
d. deactivate the drive means and the pump at the end of the cleaning cycle while maintaining the operation of the electrochemical chlorine generator;
e. activate the pump for intervals of several seconds every several minutes following the end of the cleaning cycle for a period of about one hour;
f. activate the drive means and the pump for a period of time ranging from 2 to 4 minutes to thereby relocate the pool cleaner in the pool;
g. activate the pump for intervals of several seconds every several minutes after the pool cleaner is relocated; and
h. repeat steps (f) and (g) for a predetermined period of time.

Abstract
An automated self-propelled pool cleaner having a housing, a water pump for moving water through the housing, drive means for moving the pool cleaner over the surface of the salt water pool to be cleaned, and an integral electrochemical chlorine generator mounted in the housing, includes a processor/controller that is programmed to activate the chlorine generator, the pump and drive means in predetermined operational sequences that minimize wear and tear on the water pump and drive means, while at the same time distribute and maintain a safe level of sanitizing chlorine in the pool, to thereby obviate the need for an in-line chlorinator or other chemical additive treatments; an optional automated sensor device can be provided to activate a secondary maintenance program which enables the pool cleaner to operate over prolonged periods of time as the sole means for filtering and sanitizing the pool water. An electrochemical cell manual mounting system permits the cell to be secured in place for operation and manually removed for maintenance, repair or replacement by the user without special tools or training.
