Abstract

L'invention concerne un système de distribution de liquide de lavage (100), un dispositif de lavage et un procédé de distribution de liquide de lavage. Le système de distribution de liquide de lavage (100) comprend un tuyau pour liquide (110), un régulateur de débit de liquide (120) et un module de commande électronique (130). Le tuyau pour liquide (110) comprend un premier orifice d'entrée de liquide (111) utilisé pour permettre à l'eau d'entrer, un second orifice d'entrée de liquide (112) utilisé pour injecter un liquide de lavage et au moins une ouverture d'évacuation de liquide (113) utilisée pour évacuer le liquide. Le tuyau pour liquide (110) comprend également un premier trajet de liquide (114) et un second trajet de liquide (115). Le premier orifice d'entrée (111) est en communication fluidique avec la ou les ouvertures d'évacuation de liquide (113) par l'intermédiaire du premier trajet de liquide (114), et le second orifice d'entrée de liquide (112) est en communication fluidique avec au moins une ouverture d'évacuation de liquide (113) par l'intermédiaire du second trajet de liquide (115). Le régulateur de débit de liquide (120) est raccordé au niveau du second trajet de liquide (115), et peut être ouvert et fermé afin de réguler l'injection de liquide de lavage dans un tuyau pour liquide. Le module de commande électronique (130) est relié électriquement au régulateur de débit de liquide (120) et il est utilisé pour fournir un signal de commande au régulateur de débit de liquide (120), le signal de commande étant utilisé pour commander la mise en marche ou l'arrêt du régulateur de débit de liquide (120).
