Definitions
- This invention relates generally to cleaning by use of a high pressure water stream and sanitizing by use of an ozone/water stream and, more specifically, to a cleaning and sanitizing method and apparatus in which the high pressure water stream and the ozone/water stream are discharged together, closely adjacent each other but without mixing.
- U.S. Pat. No 6,454,017 discloses various uses of ozone as a sterilant. In this patent, it is stated that ozone cannot be combined with detergent or other cleaning agents since these are vulnerable to ozone attack. It is also stated that the ozone will destroy both its own effectiveness and that of the cleaning agent rather than attacking pathogens.

Then following the removal of the soils by the detergent an aqueous ozone rinse is applied to the surface. It is stated that the ozone rinse functions to sanitize the object being cleaned and remove residual detergent.

- the ozone/water stream concentrically surrounds the high pressure water stream.
- the high pressure water and the ozone/water are discharged as closely spaced substantially parallel stream.
- the nozzles for discharging the high pressure water and the ozone/water can be movable to the object that is to be cleaned. Or, the discharge nozzles can be fixed and the article to be cleaned can be moved relative to the nozzles.
- a circulating flow path of ozone/water is provided. Along this path, one or more high pressure water discharge nozzles are provided. An ozone/water nozzle is associated with each high pressure water nozzle.

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).

- U.S. Pat. No 6,454,017 discloses various uses of ozone as a sterilant. In this patent, it is stated that ozone cannot be combined with detergent or other cleaning agents since these are vulnerable to ozone attack. It is also stated that the ozone will destroy both its own effectiveness and that of the cleaning agent rather than attacking pathogens. Pat. No. 6,455,017 discloses directing a detergent cleaning solution, preferably under pressure, onto a surface to be cleaned. Then following the removal of the soils by the detergent an aqueous ozone rinse is applied to the surface. It is stated that the ozone rinse functions to sanitize the object being cleaned and remove residual detergent. The method of Pat. No. 6,455,017 involves first directing the cleaning solution onto the surface under pressure, and then rinsing the surface by directing a flow of the ozonated water onto the surface.
- U.S. Pat. No. 5,865,995, granted Feb. 2, 1999 to William R. Nelson, and U.S. Pat. No. 6,361,688, granted Mar. 26, 2002, also to William R. Nelson, disclose systems for producing “ozonated water”, also termed “ozone/water”. As well be described, the selected one of the systems is combined in a novel way in the system of the present invention.
- An object of the present invention is to deliver a high pressure cleaning water stream and an ozone/water stream substantially simultaneously to a surface to be cleaned and sanitized. The invention is basically characterized by delivering the high pressure water stream and the ozone/water stream closely adjacent to each other but without mixing. The high pressure water stream removes particles from the surface and the ozone/water stream sanitizes the surface almost simultaneously.
- The cleaning and sanitizing system of the present invention is basically characterized by a first discharge nozzle from which a stream of high pressure water is discharged and a second discharge nozzle from which a stream of ozone/water is discharged. The first and second nozzles are positioned adjacent to each other so that the water and ozone/water streams are contiguous but the ozone/water is not delivered in the high pressure water stream. The high pressure water stream is discharged at a pressure high enough that it will exert a cleaning force on a surface to be cleaned and would convert the ozone into oxygen if the ozone/water stream were to be delivered into the high pressure water stream. In preferred form, the pressure of the high water pressure stream is at least about 100 p.s.i. More preferably, the pressure of the high pressure water stream is between 100 p.s.i. and about 1000 p.s.i. The pressure of the ozone/water stream is smaller than the pressure of the high pressure water stream and is sufficiently small that the ozone is not converted into oxygen.
- According to one aspect of the invention, the ozone/water stream concentrically surrounds the high pressure water stream.
- According to another aspect of the invention, the high pressure water and the ozone/water are discharged as closely spaced substantially parallel stream.
- The nozzles for discharging the high pressure water and the ozone/water can be movable to the object that is to be cleaned. Or, the discharge nozzles can be fixed and the article to be cleaned can be moved relative to the nozzles.
- In an embodiment of the cleaning and sanitizing system of the present invention, a circulating flow path of ozone/water is provided. Along this path, one or more high pressure water discharge nozzles are provided. An ozone/water nozzle is associated with each high pressure water nozzle. The high pressure water stream may be used to “pump” or “aspirate” ozone/water from the circulating system. As ozone/water is removed from the system, new water is delivered to the ozone/water generator and additional ozone is added to the water in the generator.
- Other advantages, and features of the invention will become apparent. From the description of the best mode set forth below, from the drawings, from the claims and from the principles that are embodied in the specific structure that are illustrated and described.

In addition to thenozzles 62, thesystem 59 may includebrushes 64, as described in U.S. Pat. No. 6,348,227 B1. Thenozzles 62 are constructed to discharge a stream of high pressure washwater 14 closely adjacent a stream of ozone/water, but without direct mixing of the two streams. - As has been described, the high

The apparatus 80 for admixing ozone to water man be one of the apparatuses disclosed in the aforementioned U.S. Pat. Nos. 5,865,995 and U.S. Pat. No. 6,361,688. The contents of these patents are hereby incorporated herein by this specific reference. - The
ozonated water conduit 52 forms a closed loop with the apparatus 80. Apump 82 pumps the ozone/water inconduit 52 to the recirculated liquid inlet of acontact tank 84. See inlet 112 in U.S. Pat. No. 6,361,688 leading intocontact tank 36 disclosed in that patent. The highpressure water stream 14 will pump or aspirate the ozone/water and remove it from the closedloop conduit 52. Because some of the ozonated water is discharged from thewater nozzles pump 82 into the inlet of thecontact chamber 84. - Preferably, the cleaning water that is discharged from the
nozzles - The illustrated embodiments are only examples of the present invention, and therefore, are non-limitive. It is to be understood that many changes in the particular structure, materials, and features of the invention may be made without departing from the spirit and scope of the invention. Therefore, it is my intention that my patent rights not be limited by the particular embodiments that are illustrated and described herein, but rather are to be determined by the following claims, interpreted according to accepted doctrine of claim interpretation, including the use of the doctrine of equivalence.
