DESCRIPTION OF THE PREFERRED EMBODIMENT

(6) Embodiments are described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense in that the scope of the present invention is defined only by the appended claims.

(7) The numeral 10 refers to a large laundry washing machine such as used in nursing homes, care facilities, etc. Machine 10 may have a capacity of 50 pounds of laundry. Machine 10 will be described as having a first water inlet 12 and a second water inlet 14. In some cases, the machine 10 will have a single water inlet.

(8) The numeral 16 refers to an ozone generator box or cabinet. A first air dryer 18 has an air line 20 extending therefrom into cabinet 16. A second air dryer 22 has an air line 24 extending therefrom into cabinet 16. Ozone generators 26, 28 and 30 are positioned in box 16 and are electrically connected to transformers in conventional fashion. Air line 20 is connected to the air inlet end 32 of ozone generator 26. A tube 36 connects the ozone outlet end 34 of ozone generator 26 and the ozone inlet end 38 of ozone generator 28. A tube 40 connects the ozone outlet end 42 of ozone generator 28 with the ozone inlet end 44 of ozone generator 30. An ozone line 46 extends from the ozone outlet end 48 of ozone generator 30.

(9) As seen, ozone generators 50, 52 and 54 are also positioned in box 16. The ozone generators 50, 52 and 54 are electrically connected to transformers in conventional fashion. Air line 24 is connected to the air inlet end 56 of ozone generator 50. A tube 58 connects the ozone outlet end 60 of ozone generator 50 and the ozone inlet end 62 of ozone generator 52. A tube 64 connects the ozone outlet end 66 of ozone generator 52 and the ozone inlet end 68 of ozone generator 54. Tube 70 extends from the ozone outlet end 71 of ozone generator 54.

(10) The numeral 72 refers to an injector box or cabinet. Injectors 74 and 76 of conventional design are positioned in box 72. The inlet side of injector 74 has a water line 78 extending therefrom to a source of water under pressure. A water valve may be positioned in line 78. An optional electrically controlled valve V1 may be imposed in line 78 inside box 72.

(11) The inlet side of injector 76 has a water line 80 extending therefrom which is connected to the source of water under pressure. A water valve may be positioned in line 80. An optional electrically controlled valve V2 may be imposed in line 80 inside box 72. The ozone line 46 is connected to the ozone inlet 82 of injector 74. The ozone line 70 is connected to the ozone inlet 84 of injector 76. A line 86 extends from the outlet end of injector 74. A line 88 extends from the outlet end of injector 76. Lines 86 and 88 are connected to the water inlets 12 and 14 of machine 10 respectively.

(12) The ozone-water fluid or mixture supplied to the machine 10 by the lines 86 and 88 provides sufficient ozone and water to the machine 10 which results in the material to be washed in a more efficient way without the use of chemicals or hot water. It has been found that the material being laundered in the machine 10 will require much less time to dry.

(13) Thus it can be seen that the invention accomplishes at least all of its stated objectives.

(14) Although the invention has been described in language that is specific to certain structures and methodological steps, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures and/or steps described. Rather, the specific aspects and steps are described as forms of implementing the claimed invention. Since many embodiments of the invention can be practiced without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
