Abstract

Apparatus for providing activated treated water to washing machines with a water treatment conduit connected between a water supply and an inlet of the washing machine, having a reactor chamber with a UV lamp and a coated metal target that generates oxidizing gases that communicate by an injector into the conduit and a transparent portion of the conduit treats the oxidated water by illumination from the UV lamp. A disinfector injects disinfecting silver ions into the treated oxidated water. A controller activates the apparatus during flow of water through the conduit. A method of activating and treating water for washing machines is disclosed.

3. The water treatment apparatus as recited in claim 2, further comprising a reset device for setting the counter to a threshold value less than the predetermined value upon replacement of the disinfecting ion generator.

4. The water treatment apparatus as recited in claim 2, wherein the disinfecting ion generator comprises:

a pair of silver wires disposed in spaced-apart relation in a housing that communicates with the water treatment conduit;

a supply of alternating electrical current connected to the silver wires, whereupon activation of the electrical current causes the silver wires to release silver ions by electrolysis.

7. The water treatment apparatus as recited in claim 1, wherein the controller connects to a supply of electrical current and further comprises a socket communicating with the controller for receiving an electrical plug of the washing machine, whereby electrical demand by the washing machine during operative cycles is detected by current flowing from the supply through the controller to the washing machine.

8. The water treatment apparatus as recited in claim 1, wherein the transparent conduit comprises quartz glass.

9. The water treatment apparatus as recited in claim 1, further comprising a monitor for operation of the disinfector, comprising:

a timer capable of tracking a duration of use of the disinfector;

an accumulator for accumulating the durations of periodic operation of the disinfector;

a comparator that compares the value of the accumulator with a predetermined value; and

12. The water treatment apparatus as recited in claim 1, further comprising an initializer for setting the controller to operate the water treatment apparatus, the initializer configured for detecting a nominal electrical current communicated to the washing machine during a non-operational period with the washing machine connected to a supply of electrical current, so subsequent to initialization the controller compares the threshold with an electrical demand during the washing machine cycle for supply of washing water to the tub of the washing machine for determining when to operate the apparatus.

13. The water treatment apparatus as recited in claim 12, further comprising a selectively actuated valve disposed between the supply of water and the water inlet of the water treatment conduit, the valve normally closed and selectively opened upon detection by the controller of the washing water supply portion of the washing machine cycle.

24. The water treatment apparatus as recited in claim 1, further comprising a washing machine that communicates with the water treatment conduit.

14. A water treatment apparatus for providing activated wash water to washing machines for cleaning clothing, comprising:
