Abstract
Description
Die Erfindung betrifft eine Haushalt-Geschirrspülmaschine mit wechselnder Beschickung von wenigstens zwei Sprüheinrichtungen bzw. Gruppen von Sprüheinrichtungen, die von wenigstens einer Umwälzpumpe mit Spülflüssigkeit zur Beaufschlagung von zu reinigendem Gut beliefert werden.The invention relates to a household dishwasher with changing loading of at least two spray devices or groups of spray devices, of at least a circulating pump with rinsing liquid to apply to be cleaned Be well supplied.
Haushalt-Geschirrspülmaschinen mit Wechselbetrieb der Sprühebenen sind seit langem bekannt, z.B. aus der DE-OS 24 28 991. Bei handelsüblichen Haushalt-Geschirrspülmaschinen werden die wenigstens zwei Sprüheinrichtungen gleichzeitig mit der von einer Umwälzpumpe geförderten Flüssigkeit beschickt. Bei der Haushalt-Geschirrspülmaschine nach der DE-OS 24 28 991 wird aber zur Erzielung eines gleichen oder besseren Reinigungsergebnisses wie bei den vorgeschilderten handelsüblichen Haushalt-Geschirrspülmaschinen jede Sprüheinrichtung wechselnd nacheinander mit der von einer Umwälzpumpe geförderten Flüssigkeit beschickt, um so den vollen Druck der Umwälzpumpe nur an einer Sprüheinrichtung wirken zu lassen und eine geringere Flüssigkeitsmenge und geringere Energie zum Umwälzen und auch zum Erwärmen der umgewälzten Flüssigkeit zu benötigen.Household dishwashers with alternating operation of the spray levels have long been known e.g. from DE-OS 24 28 991. In commercial household dishwashers the at least two spray devices simultaneously with that of a circulation pump fed liquid. In the household dishwasher after DE-OS 24 28 991 is used to achieve the same or better cleaning result as with the above-mentioned standard household dishwashers Spraying device alternately in succession with the one conveyed by a circulation pump Liquid is fed, so that the full pressure of the circulation pump is only at one spray device to work and a lower amount of liquid and less energy to Circulation and also needed to heat the circulated liquid.
Zu den Sprüheinrichtungen wird die von der Umwälzpumpe geförderte Spülflüssigkeit mittels Flüssigkeitszuleitungen geführt. Die in diesen Flüssigkeitszuleitungen während des Umwälzens befindliche Menge an Spülflüssigkeit ―üblicherweise als Totwassermenge bezeichnet - ist während des Durchströmens der Flüssigkeitszuleitungen nicht an der Beaufschlagung des zu reinigenden Gutes beteiligt. Diese in den Flüssigkeitszuleitungen während des Umwälzens befindliche Menge an Spülflüssigkeit muß, um eine ausreichende Reinigungswirkung zu erzielen, auch bei Haushalt-Geschirrspülmaschine mit wechselnder Beschickung von wenigstens zwei Sprüheinrichtungen bzw. Gruppen von Sprüheinrichtungen berücksichtigt werden. Die verwendete Flüssigkeitsmenge muß also nach dem Inhalt des längsten Beschickungsweg ausgelegt werden, nämlich, da die Umwälzpumpe üblicherweise im untersten Bereich einer Haushalt-Geschirrspülmaschine angeordnet ist, dem Inhalt der Flüssigkeitszuleitungen zu der oberen Sprüheinrichtung bzw. Gruppe von Sprüheinrichtungen. Bei Betrieb der unteren Sprüheinrichtung bzw. Gruppe von Sprüheinrichtungen mit, da die untere Sprüheinrichtung üblicherweise direkt oberhalb der Umwälzpumpe angeordnet ist, einem wesentlich kürzerem Beschickungsweg z.B. nach der DE-OS 24 28 991 ist daher im Grunde eine überflüssige Menge von Spülflüssigkeit vorhanden, die nicht zur Beaufschlagung des zu reinigenden Gutes genutzt wird.The rinsing liquid conveyed by the circulation pump is added to the spray devices Liquid supply lines led. The in these liquid supply lines during the circulation amount of rinsing liquid usually referred to as the amount of dead water - is not at the point of action during the flow through the liquid supply lines of the goods to be cleaned. This in the liquid supply lines during the circulation amount of rinsing liquid must have a sufficient cleaning effect to achieve, even with household dishwashers with changing loads taken into account by at least two spray devices or groups of spray devices become. The amount of liquid used must therefore be based on the contents of the longest feed path be interpreted, namely, since the circulation pump is usually in the lowest Area of a household dishwasher is arranged, the content of the liquid feed lines to the upper spray device or group of spray devices. At Operation of the lower spray device or group of spray devices with, since the lower Spray device is usually arranged directly above the circulation pump, one much shorter loading path e.g. according to DE-OS 24 28 991 is therefore basically there is an unnecessary amount of flushing liquid that is not intended to act upon the cleaning good is used.
