TOP SURFACE DRYING NOZZLE FOR CAR WASH

PROBLEM TO BE SOLVED: To decrease or eliminate noise generated by a top surface drying nozzle. SOLUTION: The top surface drying nozzle 6 includes blast introduction tubes 16 on its upper surface through openings of which high-pressure winds from a blower 8 are introduced, a slit-like blast blow-out opening 17 formed at its lower surface, and diffusers 18 formed internally for diffusing a part of the high-pressure winds introduced from the blast introduction tubes 16 in the longitudinal direction of the inside of the top surface drying nozzle 6. In an internal position to divide the blast introduction tube 16 almost in half in the width direction of the top surface drying nozzle 6, a current plate 19 is located which continues from the upper surface toward the lower surface along an inner configuration. A cutout 20 is formed at the lower end of the current plate 19 facing the blast blow-out opening 17. Front and rear ends of the blast blow-out opening 17 are provided with rolling prevention bodies 21 which have folded parts formed upward throughout the width direction of the top surface drying nozzle 6. A sound absorption chamber 22 is formed on the upper surface of the top surface drying nozzle 6 except the blast introduction tubes 16. COPYRIGHT: (C)2009,JPO&INPIT
