The cleaning nozzle includes air and fluid inlets. The air inlet is coupled to an air conduit which includes a first control valve, and the fluid inlet is coupled to a fluid conduit which includes a second control valve. A lever or button is coupled to a first valve for discharging pressurized air through the air conduit. The air and fluid conduits are coupled to an outlet chamber which has a spray head. Compressed air is discharged from the spray head for allowing kitchen utensils to be prewashed with air. The lever or button is further coupled to a second valve for discharging pressurized fluid through the fluid conduit. The fluid conduit is also coupled to the outlet chamber for allowing a discharge of pressurized air and fluid to be sprayed from the nozzle to further prewash the kitchen utensils. ## Claims ### Claim 1 A dual function cleaning nozzle assembly configured to prewash kitchen utensils comprising: a first valve having a first and second position and a second valve having a first and second position, the first and second valves being closed when situated in the first positions; an air inlet coupled to an air conduit for controlling the flow of pressurized air through the air conduit; a fluid inlet coupled to a fluid conduit for controlling the flow of pressurized fluid through the fluid conduit; a lever having a first, second and third position, the lever being coupled to the first and second valves, the first valve being opened when the lever is pressed to the second position, wherein the lever is configured to move the first valve to the second position for allowing the air to flow through the air conduit; an outlet chamber having a spray head cleaning nozzle disposed at the end of said outlet chamber, coupled to the first and second valves, whereby the kitchen utensils are prewashed by a discharge of pressurized air and pressurized fluid from the cleaning nozzle when the lever is actuated to the third position, wherein the lever is configured to move the second valve to the second position for allowing the pressurized fluid to flow through the fluid conduit; and a self-cleaning detachable scraper is coupled substantially to a side of the nozzle, the detachable scraper having an elongated uniform solid body comprised of a semiflexible material for allowing excess food and debris to be scraped off kitchen utensils. ### Claim 2 (depends on 1) A dual function cleaning nozzle according to claim 1, wherein the lever has a general shape configured to allow a user's fingers to grip thereon, wherein said lever is further configured to function in cooperation with a handle to allow the user's thumb to engage thereon. ### Claim 3 (depends on 1) A dual function cleaning nozzle according to claim 1, wherein the fluid is water. ### Claim 4 (depends on 3) A dual function cleaning nozzle according to claim 3, wherein the temperature of the water is at least 110° F. ### Claim 5 (depends on 1) A dual function cleaning nozzle according to claim 1, wherein the fluid is a combination of water and a soap type substance. ### Claim 6 (depends on 1) A dual function cleaning nozzle according to claim 1, wherein the fluid is a combination of water and a sanitizing agent. ### Claim 7 (depends on 1) A dual function cleaning nozzle according to claim 1, further including a contoured handle. ### Claim 8 (depends on 1) A dual function cleaning nozzle according to claim 1, wherein the outlet chamber is coupled to a detachable noise suppression nozzle configured substantially in the shape of a cylinder for reducing the sound intensity generated by the spray head cleaning nozzle. ### Claim 9 (depends on 1) A dual function cleaning nozzle according to claim 1, wherein an air compressor is coupled to the air inlet connector. ### Claim 10 (depends on 1) A dual function cleaning nozzle according to claim 1, wherein the lever is pivotable. ### Claim 11 (depends on 1) A dual function cleaning nozzle according to claim 1, wherein the pressurized air flowing through the cleaning nozzle removes debris and food particles from the scraper when the lever is actuated to the first position. ### Claim 12 (depends on 1) A dual function cleaning nozzle according to claim 1, wherein the pressurized air and fluid flowing through the cleaning nozzle further removes debris and food particles from the scraper when the lever is actuated to the second position. ### Claim 13 A dual function cleaning nozzle assembly configured to prewash kitchen utensils comprising: a first valve having a first and second position and a second valve having a first and second position; an air inlet coupled to an air conduit for controlling the flow of pressurized air through the air conduit; a fluid inlet coupled to a fluid conduit for controlling the flow of pressurized fluid through the fluid conduit; a lever having a first, second and third position, the lever being coupled to the first and second valves, the first valve being opened when the lever is pressed to the second position, wherein the lever is configured to move the first valve to the second position for allowing the air to flow through the air conduit; an outlet chamber having a spray head cleaning nozzle disposed at the end of said outlet chamber, coupled to the first and second valves, whereby the kitchen utensils are prewashed by a discharge of pressurized air and pressurized fluid from the cleaning nozzle when the lever is actuated to the third position; and a self-cleaning detachable scraper is coupled to the nozzle, the detachable scraper having an elongated uniform solid body comprised of a semiflexible material for allowing excess food and debris to be scraped off kitchen utensils, wherein the pressurized air or mixture of pressurized air and fluid flowing through the cleaning nozzle removes debris and food particles from the scraper. ### Claim 14 (depends on 13) A dual function cleaning nozzle according to claim 13, wherein the second valve being opened when the lever is pressed to the third position for allowing fluid to flow through the fluid conduit, whereby the kitchen utensils are further prewashed by a discharge of a pressurized mixture of air and fluid from the cleaning nozzle when the lever is opened to the third position.
