PURPOSE: To increase the flow of liquid detergent at the high speed travel time to obtain a sufficient cleaning effect and eliminate the waste of liquid detergent at the low speed travel time by providing a means for controlling in such a way as to change the flow of liquid detergent according to the travel speed.
CONSTITUTION: A control part 20 includes a microcomputer and controls each part of a car washing machine formed of an inverter 1, solenoid valves 10, 11, and the like according to the control input of a control panel 21. The control part 20 is provided with a flow control part 20a for regulating the flow of liquid detergent by opening/closing the solenoid valves 10, 11. The flow control part 20a controls in such a way as to open the solenoid valves 10, 11 by the specified opening/closing synchronization To, that is, by the time provided by a valve opening timer T out of one second, for instance. The solenoid valves 10, 11 are thereby opened/closed repeatedly every fixed cycle so as to regulate the flow of liquid detergent by the valve open time T of each synchronization.
