Abstract

The present invention is a device and method for ozonating water and applying the ozonated water to surfaces for cleaning purposes. The instant invention allows a user to transform water into a liquid with more robust cleaning properties conveniently and in a short time. The present invention includes a cleaning apparatus having a reservoir containing water, the reservoir able to be easily manipulated by a user to dispense the water, a device for increasing the level of oxidative properties in the water, and a circulation flow path communicating with the reservoir and the device to allow at least some of the water in the reservoir to flow from the reservoir to the device and back to the reservoir.

Claims

1. A cleaning apparatus comprising:

a reservoir containing a liquid, said reservoir able to be easily manipulated by a user to dispense said liquid;

a device for increasing the level of oxidative properties in said liquid;

a circulation flow path communicating with said reservoir and said device to allow at least some of said liquid in said reservoir to flow from said reservoir to said device and back to said reservoir;

wherein said circulation flow path includes a recirculation flow path and a treatment flow path, where said treatment flow path directs water from said recirculation flow path to said device and back to said recirculation flow path; and

wherein said treatment flow path includes a pre-treatment region upstream of said device and downstream of a diversion of said treatment flow path from said recirculation flow path.

2. An apparatus as defined in claim 1, wherein said pre-treatment region is a deionization resin bed.

3. A cleaning apparatus comprising:

a spray bottle containing a liquid, said spray bottle able to be easily manipulated by a user to dispense said liquid;

a device for increasing the level of oxidative properties in said liquid;

a circulation flow path communicating with said spray bottle and said device to allow at least some of said liquid in said spray bottle to flow from said spray bottle to said device and back to said spray bottle.

4. A cleaning apparatus comprising:

a carafe containing a liquid, said carafe able to be easily manipulated by a user to dispense said liquid;

a device for increasing the level of oxidative properties in said liquid;

a circulation flow path communicating with said carafe and said device to allow at least some of said liquid in said carafe to flow from said carafe to said device and back to said carafe.

5. A cleaning apparatus comprising:

a reservoir containing a liquid, said reservoir able to be easily manipulated by a user to dispense said liquid;

a device for increasing the level of oxidative properties in said liquid;

a circulation flow path communicating with said reservoir and said device to allow at least some of said liquid in said reservoir to flow from said reservoir to said device and back to said reservoir;

wherein said circulation flow path includes a recirculation flow path and a treatment flow path, where said treatment flow path directs water from said recirculation flow path to said device and back to said recirculation flow path; and

wherein said treatment flow path includes a pre-treatment region downstream of said device and upstream of a reconvergence of said treatment flow path and said recirculation flow path.

6. An apparatus as defined in claim 5, wherein said post-treatment region is a lead abatement filter.

7. A residential cleaning apparatus comprising:

a base unit including an ozone generator;

a reservior for holding water and for use by a user to selectively dispense water, said reservoir being selectively and fluidically attachable to said base unit;

a circulation flow path formed between said reservoir and said base unit, and fluidically and at least in part connecting said reservoir with said ozone generator; and

wherein said at least some of said water flows in said circulation flow path between said reservoir and said ozone generator and back to said reservoir, said ozone generator dispensing ozone into said water.

8. An apparatus as defined in claim 7, wherein:

said circulation flow path includes a recirculation flow path and a treatment flow path, said recirculation flow path extending between said reservoir, said base, and back to said reservoir, and said treatment flow path extending from said recirculation flow path to said ozone generator and back to said recirculation flow path; and

wherein said ozone generator dispenses ozone into said water in said treatment flow path.

9. An apparatus as defined in claim 8, wherein:

said treatment flow path includes a deionization filter media positioned upstream of said ozone generator.

10. An apparatus as defined in claim 9, wherein said deionization filter media is positioned in said base unit.

11. An apparatus as defined in claim 9, further comprising:

a cartridge selectively and fluidically connectable to said base unit, and forming part of said treatment flow path; and

wherein said deionization filter media is positioned in said cartridge.

12. An apparatus as defined in claim 8, further comprising:

a mixing device connected between said treatment flow path and said recirculation flow path, said mixing device to help mix the treated water in the treatment flow path with the untreated water in the recirculation flow path.

13. An apparatus as defined in claim 12, wherein:

said mixing device is a venturi.

14. An apparatus as defined in claim 8, wherein:

a pump is positioned in said circulation flow path to assist in moving said water along said circulation flow path.

15. An apparatus as defined in claim 7, wherein:

said base unit is positionable on a support surface.

16. An apparatus as defined in claim 7, wherein:

said base unit is built into a household appliance.

17. An apparatus as defined in claim 7, wherein:

said reservoir is a spray bottle.
