Abstract
There is provided automatic car wash equipment for positioning a forced air dryer including a blower towards vehicles being washed. The blower produces high velocity air and contains a nozzle for directing the high velocity air towards the vehicles. The blower and a positioning motor are mounted to a support frame, under which an on-coming vehicle passes. The blower is positioned according to the output signal from an ultrasonic imaging sensor mounted to the support frame. The relative position of the blower is measured by a linear potentiometer mounted to the piston which positions the blower. Additional detection devices are provided for over-riding the ultrasonic signal should contact be eminent between the blower and various parts of an on-coming vehicle.
