Während des Spülprogramms tritt Spülflüssigkeit durch alle ausgebildeten Ausbrüche in den als Zuflussleitung ausgebildeten Rohren des Geschirrkorbs. Durch die engen Zuflußrohre entsteht ein deutlicher Druckabfall bis zu dem entferntesten Punkt vom Zufluss der Rohre. Aufgrund dessen ist die Spül- bzw. Sprühleistung in nicht allen Bereichen des Geschirrkorbs gleichermaßen ausgebildet, so dass in Bereichen, die vom Zufluss am entferntesten sind, der Sprühstrahl mit geringerer Geschwindigkeit auf das Spülgut trifft.From the DE-OS 27 02 644 a dish rack for dishwashers is known, which provides in the storage area tubes, which are each provided with openings to pressurize the washware located immediately above it. During the wash program, rinse liquid passes through all the outbreaks formed in the pipes of the dish rack formed as an inflow line. Due to the narrow inlet pipes, a significant pressure drop occurs up to the farthest point from the inflow of the pipes. Due to this, the rinsing or spraying performance is not formed in the same way in all areas of the crockery basket, so that in areas which are farthest from the inflow, the spray jet impinges on the items to be washed at a lower speed.

Dieser Nachteil wiegt umso schwerer, wenn in diesen vom Zufluss weit entfernten Bereichen des Geschirrkorbs besonders hartnäckig verschmutztes Spülgut eingeordnet ist und so eine unterschiedliche Spülqualität in einem Geschirrkorb erzielt wird.This disadvantage weighs all the more difficult, if in these far away from the inflow areas of the dish rack particularly stubborn soiled items is classified and so a different rinsing quality is achieved in a dish rack.
