Abstract
A radio remote-controlled automatic vehicle wash system is activated by an infrared motion sensor. A hand-held transmitter activates an optional garage door mechanism of the system to open and activate the wash system. Within a controller is housed a micro-controller programmed to process inputs from the garage door, an RF transmitter, a thermistor and an infrared motion sensor. When predetermined specified conditions are met, the controller activates a solenoid valve to allow pressurized water to flow through distribution pipes at each side of the vehicle, and under it. Nozzles connected to the distribution pipes spray water in a high velocity 45.degree. fan-like pattern to remove dirt, salt and debris from the surface of the vehicle and the undercarriage. Each nozzle contains a check valve to prevent water from seeping out once the system is depressurized to conserve water and to assure that when the solenoid valve is opened there is no significant delay in opening the nozzles due to absence of water in the distribution pipes. The system is adaptable to any garage or carport as well as with automatic garage door opening.
