Cleaning and sanitizing system

Abstract

A high pressure water stream ( 14 ) is discharged onto a surface to be cleaned. An ozone/water stream ( 16 ) is discharged on the same surface for sanitizing the surface. The high pressure water and ozone/water streams ( 14, 16 ) are discharged simultaneously along closely adjacent paths that are either parallel (FIG. 3 ) or concentric (FIG. 2 ). The water pressure is at least about 100 p.s.i and is preferably between 100 p.s.i and 1000 p.s.i. The nozzles that discharge the streams ( 14, 16 ) may be movable relative to the object(s) that receives the high pressure water and ozone/water (FIG. 1 ). Or, they may be fixed and the object may be movable relative to them (FIG. 4 ).

1 . A cleaning and sanitizing system, comprising: 
 a first discharge orifice;    a first conduit for delivering water to the first discharge orifice to be discharged by the first discharge orifice as a first stream;    a second discharge orifice;    a second conduit for delivering ozone/water to the second discharge orifice, to be discharged from the second discharge orifice as a stream of ozone/water;    a source of water connected to the first conduit for delivering water into and through the first conduit and out from the first discharge orifice as a stream of high pressure water;    a source of ozone/water connected to the second conduit for delivering ozone/water into and through the second conduit and out from the second discharge orifice as a stream of ozone/water;    said first and second orifices being positioned and secured adjacent to each other.    
     
     
         2 . The system of  claim 1 , wherein the pressure of the high pressure water stream is at least about 100 psi.  
     
     
         3 . The system of  claim 1 , wherein first orifice and the second orifice are permanently secured closely adjacent one another.  
     
     
         4 . The system of  claim 1 , wherein first orifice and the second orifice are secured in a fixed distal relationship with respect to one another.  
     
     
         5 . The system of  claim 1 , wherein the second discharge orifice is positioned to discharge the stream of ozone/water along a path that is laterally adjacent the path of the high pressure water stream that is discharged from the first discharge orifice.  
     
     
         6 . The system of  claim 1 , wherein the first and second discharge orifices are a part of a single wand having a first end that includes inlets for sections of the first and second conduits that are in the wand and a second end that includes the first and second discharge orifices.  
     
     
         7 . The system of  claim 6 , wherein the first and second discharge orifices are fixed in position with respect to each other.  
     
     
         8 . The system of  claim 7 , wherein said first conduit includes a first hose section and said second conduit includes a second hose section.  
     
     
         9 . The system of  claim 1 , wherein the second discharge orifice is positioned to discharge the stream of ozone/water along a path that concentrically surrounds the path of the high pressure water stream that is discharged from the first discharge orifice.  
     
     
         10 . A cleaning device, comprising: 
 a first fluid outlet;    a second fluid outlet;    a source of high pressure water connected in fluid communication to the first fluid outlet; and    a source of ozone/water connected in fluid communication to the second fluid outlet;    wherein the first fluid outlet and the second fluid outlet are secured to the device closely adjacent one another.    
     
     
         11 . The device of  claim 10 , wherein first outlet and the second outlet are secured to the device in a fixed spatial relationship with respect to one another.  
     
     
         12 . The system of  claim 10 , wherein the second conduit is positioned to deliver ozone/water along a path that concentrically surrounds the path of the water delivered by the first conduit.
