Car washing machine
专利汇可以提供Car washing machine专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve cleaning performance by providing an ultrasonic detecting device for detecting a boundary between a front window and a bonnet face or a ceiling face of a car, and changing over the driving speed of a driving means for a car washing machine frame on detection signals issued by the above detecting device to obtain the optimum cleaning speed at each spot.
CONSTITUTION: A car washing machine 1 has a gate type frame 2 which is freely reciprocated on a rail 3 by the functioning of a driving means 7, and the frame 2 is provided with a rotary brush device B and a drying device D. In this case, a reflection type ultrasonic detecting device 51 for detecting the height of a car and the position of a car body is provided at an upper part in the front along an advancing direction of the frame 2 to detect boundaries of the frame 2 to detect boundaries between a front window and both a bonnet face and a ceiling face of the car. The car washing machine 1 is controlled by changing-over a driving means 7 on the results of the above detection to a low speed side when the upper face rotary brush 5 of the rotary brush device B is at a position corresponding to the bonnet face and to a high speed side when the rotary brush 5 is at a position corresponding to the ceiling face.
