Abstract

L'invention concerne une machine de fabrication automatique de lait de formule pour un usage domestique et un procédé de commande associé. La machine de fabrication de lait de formule comprend un corps de machine doté d'un mélangeur (6), d'une tasse destinée à contenir du lait en poudre (24), d'un mécanisme de transport de lait en poudre, d'un moteur d'alimentation en lait en poudre (51), d'un réservoir d'eau (3), d'une conduite d'alimentation en eau et d'un circuit de commande. Le mélangeur (6) est doté d'une chambre de mélange et d'un orifice d'évacuation de liquide (61), l'orifice d'évacuation de liquide (61) étant en communication avec la chambre de mélange. Le mécanisme de transport de lait en poudre est disposé dans la tasse destinée à contenir du lait en poudre (24) et est raccordé par transmission au moteur d'alimentation en lait en poudre (51). La tasse destinée à contenir du lait en poudre (24) est dotée d'une ouverture d'alimentation en lait en poudre (242) en communication avec la chambre de mélange. Le réservoir d'eau (3) est en communication avec la chambre de mélange par le biais de la conduite d'alimentation en eau. La conduite d'alimentation en eau est dotée d'un capteur d'écoulement (40), d'une pompe à eau (53), d'un détecteur de température d'arrivée d'eau (20) et d'un récipient de chauffage d'eau (52). Le capteur d'écoulement (40) et le détecteur de température d'arrivée d'eau (20) sont situés entre le récipient de chauffage d'eau (52) et le réservoir d'eau (3) de sorte que, lorsque le réservoir d'eau (3) alimente le mélangeur (6) en eau, l'eau s'écoule à travers le capteur d'écoulement (40) et le détecteur de température d'arrivée d'eau (20), puis s'écoule dans le récipient de chauffage d'eau (52). Les composants électriques sont respectivement connectés électriquement au circuit de commande. Après l'acquisition d'informations de volume et d'informations de température de l'eau qui s'écoule dans le récipient de chauffage d'eau (52), le circuit de commande peut commander la puissance du récipient de chauffage d'eau (52) pour obtenir avec précision une température d'eau requise pour la fabrication du lait.
