ABSTRACT:
The dryer for a motor vehicle washing and drying system includes three downwardly-facing nozzles. The nozzles oscillate in a synchronized manner, with two side nozzles oscillating over a limited range only. A center nozzle, disposed between the two side nozzles, oscillates over a wider range to drive water on the upper surface of the vehicle towards the side nozzles. The side nozzles then drive the water along the contours of the vehicle surface down the sides of the vehicle using the Coanda effect. One of the side nozzles as well as the center nozzle is moved in an inward or outward direction depending upon the sensed width of the vehicle. The center nozzle is rotated in a forward or rearward direction as the vehicle moves underneath the dryer. Each nozzle contains a unique ovoid-shaped member disposed in the nozzle to accelerate and concentrate the output of the nozzles. The distance between the vehicle and the center nozzle is sensed by a triangulation sensor so that the output of the center nozzle may be adjusted as the height of the vehicle varies, and so that the center nozzle may be rotated in the forward or rearward direction.
