Abstract

L'invention concerne un dispositif de distribution d'eau potable et un procédé de commande et un appareil de commande associés. Le dispositif de distribution d'eau (1000) comprend un réservoir d'eau de refroidissement (200), un réservoir d'eau gazéifiée (300), une pompe à eau qui pompe l'eau froide vers le réservoir d'eau gazéifiée, une sortie d'eau froide et une sortie d'eau gazéifiée. Sur le trajet de sortie d'eau allant du réservoir d'eau froide à un trajet d'écoulement de déversement d'eau de la sortie d'eau froide se trouve une électrovanne primaire (500). Sur le trajet de sortie d'eau allant du réservoir d'eau gazéifiée au trajet d'écoulement de déversement d'eau de la sortie d'eau gazéifiée se trouve une électrovanne secondaire (600). Le procédé de commande de déversement d'eau consiste à : recevoir une instruction d'utilisateur ; lorsqu'il est déterminé selon une instruction de déversement d'eau que le distributeur d'eau distribue de l'eau gazéifiée, commander à l'électrovanne secondaire de s'ouvrir et maintenir l'électrovanne primaire dans un état fermé ; avant le déversement de l'eau gazéifiée par les extrémités de distributeur d'eau, commander l'ouverture et le début du temps de comptage de l'électrovanne primaire ; et lorsque le comptage de temps atteint un premier temps prédéfini, commander à l'électrovanne secondaire de se fermer jusqu'à ce que le comptage de temps atteigne un second temps prédéfini, puis commander à l'électrovanne primaire de se fermer. L'électrovanne primaire est commandée pour s'ouvrir avant le déversement de l'eau gazéifiée par les extrémités du distributeur d'eau de façon à relâcher la pression et empêcher ainsi le côté de l'électrovanne primaire d'être incapable de s'ouvrir en raison d'une pression excessive.
