APPAREIL D'ENTRETIEN DU LINGE MUNI D'UNE COMMANDE DE POMPE
Abstract:
(DE)
Wäschepflegegerät (100) mit einer Pumpe (105) zum Pumpen von Waschflüssigkeit, wobei die Pumpe (105) eine Saugkammer (107) und eine Umpumpdruckkammer (115) umfasst, wobei die Umpumpdruckkammer (115) mit der Saugkammer (107) durch eine Umpumpsaugverbindung (129) fluidtechnisch verbunden ist, wobei die Pumpe (105) eine Abpumpdruckkammer (111) umfasst, welche einen Abpumpdruckstutzen (113) zum fluidtechnischen Verbinden mit einer Abpumpdruckleitung aufweist, wobei die Abpumpdruckkammer (111) mit der Saugkammer (107) durch eine Abpumpsaugverbindung (119) verbunden ist, wobei die Pumpe (105) einen ersten Pumpenmotor (135) zum Pumpen der Waschflüssigkeit aus derAbpumpdruckkammer (111) und einen zweiten Pumpenmotor(139) zum Pumpen der Waschflüssigkeit aus der Umpumpdruckkammer (115) aufweist, und einer Pumpensteuerung (133) zum Steuern des ersten und zweiten Pumpenmotors (135,139). Die Umpumpsaugverbindung (129) und die Abpumpsaugverbindung (119) sind in der Saugkammer (107) strömungstechnisch gekoppelt. Die Pumpe (105) umfasst ein Filterelement zum Filtern von Verunreinigungen aus der Waschflüssigkeit, wobei das Filterelement in der Saugkammer (107) angeordnet ist. Die Pumpensteuerung (133) ist ausgebildet, in einem Aktivierungszeitabschnitt einen der beiden Pumpenmotoren (135,139) zu aktivieren, um Waschflüssigkeit aus der Saugkammer (107) durch das Filterelement und durch eine der Saugverbindungen (119, 129) in eine der Druckkammern (111,115) zu pumpen, und der aktivierte Pumpenmotor (135, 139) ist ausgebildet, während des Aktivierungszeitabschnitts Waschflüssigkeit aus der anderen Saugverbindung (119,129) anzusaugen, um an der anderen Saugverbindung (119, 129) angelagerte Verunreinigungen durch das Filterelement und durch die eine Saugverbindung (119, 129) in die eine Druckkammer (111,115) zu pumpen.
(EN)
Laundry-care appliance (100) having a pump (105) for pumping washing liquid, wherein the pump (105) comprises an intake chamber (107) and a circulating pressure chamber (115), wherein the circulating pressure chamber (115) is connected fluidically to the intake chamber (107) by way of a circulating intake connection (129), wherein the pump (105) comprises a drain pressure chamber (111) which has a drain pressure stub (113) for connecting fluidically to a drain pressure line, wherein the drain pressure chamber (111) is connected to the intake chamber (107) by way of a drain intake connection (119), wherein the pump (105) has a first pump motor (135) for pumping the washing liquid out of the drain pressure chamber (111) and a second pump motor (139) for pumping the washing liquid out of the circulating pressure chamber (115), and a pump controller (133) for controlling the first and second pump motor (135, 139). The recirculating intake connection (129) and the drain intake connection (119) are coupled in flow terms in the intake chamber (107). The pump (105) comprises a filter element for filtering contaminations out of the washing liquid, wherein the filter element is arranged in the intake chamber (107). The pump controller (133) is configured to activate one of the two pump motors (135, 139) in an activation time period, in order to pump washing liquid out of the intake chamber (107) through the filter element and through one of the intake connections (119, 129) into one of the pressure chambers (111, 115), and the activated pump motor (135, 139) is configured to suck washing liquid out of the other intake connection (119, 129) during the activation time period, in order to pump contaminants which are deposited on the other intake connection (119, 129) through the filter element and through the one intake connection (119, 129) into the one pressure chamber (111, 115).
(FR)
L'invention concerne un appareil d'entretien du linge (100) muni d'une pompe (105) servant à pomper un liquide de lavage. La pompe (105) présente une chambre d'aspiration (107) et une chambre de pression de transvasement (115), la chambre de pression de transvasement (115) est en communication fluidique avec la chambre d'aspiration (107) par un raccord d'aspiration de transvasement (129), la pompe (105) présente une chambre de pression d'évacuation (111) munie d'un embout de pression d'évacuation (113) pour sa communication fluidique avec une conduite de pression d'évacuation, la chambre de pression d'évacuation (111) est raccordée à la chambre d'aspiration (107) par un raccord d'aspiration d'évacuation (119), et la pompe (105) présente un premier moteur de pompe (135) pour le pompage du liquide de lavage hors de la chambre de pression d'évacuation (111) et un second moteur de pompe (139) pour le pompage du liquide de lavage hors de la chambre de pression de transvasement (115), et une commande de pompe (133) commandant le premier et le second moteur de pompe (135, 139). Le raccord d'aspiration de transvasement (129) et le raccord d'aspiration d'évacuation (119) sont accouplés fluidiquement dans la chambre d'aspiration (107). La pompe (105) comprend un élément filtrant servant à filtrer les impuretés présentes dans le liquide de lavage, l'élément filtrant étant agencé dans la chambre d'aspiration (107). La commande de pompe (133) est conçue pour activer un des deux moteurs de pompe (135, 139) dans un laps de temps d'activation, pour pomper le liquide de lavage hors de la chambre d'aspiration (107) dans une des chambres de pression (111, 115) en passant par l'élément filtrant et par un des raccords d'aspiration (119, 129), et le moteur de pompe activé (135, 139) est conçu pour, pendant le laps de temps d'activation, aspirer le liquide de lavage hors de l'autre raccord d'aspiration (119, 129), pour pomper les impuretés déposées sur l'autre raccord d'aspiration (119, 139) dans la chambre de pression (111, 115) en passant par l'élément filtrant et par le raccord d'aspiration (119, 129).
