Abstract
An aerial washing method for obtaining washing effects almost equal to those of underwater washing is embodied. An jet opening 12 for jetting high-pressure water in a direction generally parallel to the direction the nozzle's axis is provided in a nozzle port 11 of a washing nozzle 10, and a negative pressure is formed in the nozzle port 11 by jetting a high-pressure water jet. A low-pressure water inlet 14 and a gas inlet 15 through which low-pressure water and a gas, respectively, are sucked in using this negative pressure are provided in the washing nozzle 10. The low-pressure water and the gas are engulfed in the high-pressure water jet, and the resultant high-pressure jet of water is aerially directed against an object to wash it.
