Der Sicherheitsüberlauf (1) weist neben der Überlaufkante (4) zum Spülraum (3) zwei Kammern (5, 6) und einen Ablauf (7) auf, der in eine nicht gezeigte Bodenwanne oder in das Abwassernetz mündet. Ferner besitzt der Sicherheitsüberlauf (1) eine Flüssigkeitsleitung (8), welche die einzige Strömungsverbindung vom Spülraum (3) zum Sicherheitsüberlauf (1) bildet, wobei die Flüssigkeitsleitung (8) von der Überlaufkante (4) am Spülraum (3) in ein unterhalb der Überlaufkante (4) ausgebildetes Wasserreservoir (9) der ersten Kammer (5) führt, welches zur Aufnahme einer austauschbaren Wasservorlage dient. Die erste Kammer (5) ist von der strömungsmäßig nachgeschalteten und den Ablauf (7) aufweisenden zweiten Kammer (6) durch einen Überlauf (10) getrennt, wobei der Überlauf (10) in Form-einer Wand ausgebildet ist, dessen Überlaufniveau oberhalb der zum Spülraum angeordneten Überlaufkante (4) liegt. Um zu vermeiden, dass die Wasservorlage bspw. während eines gebläseunterstützten Trocknungsgangs vom im Spülraum (3) vorliegenden Überdruck in die zweite Kammer (6) gedrückt wird, ist das Überlaufniveau des Überlaufs (10) in dieser Ausführung um ein mehrfaches höher als das höchste erreichbare Niveau der Wasservorlage in der ersten Kammer (5) ausgebildet. Grundsätzlich reicht es aber aus, wenn der Überlauf (10) gerade so hoch bemessen ist, dass eine Wasservorlage während eines geregelten Spülprogrammlaufs nicht aus der ersten Kammer (5) über den Überlauf (10) in die zweite Kammer (6) fließt.The safety overflow (1) has two chambers in addition to the overflow edge (4) to the washing compartment (3) (5, 6) and a drain (7) which in a bottom pan, not shown, or in the Sewer network opens. Furthermore, the safety overflow (1) has a fluid line (8), which forms the only flow connection from the washing compartment (3) to the safety overflow (1), wherein the liquid line (8) from the overflow edge (4) on the washing compartment (3) in a below the Overflow edge (4) formed water reservoir (9) of the first chamber (5) leads, which for Recording a replaceable water mask is used. The first chamber (5) is of the fluidly downstream and the outlet (7) having second chamber (6) separated by an overflow (10), the overflow (10) being in the form of a wall, whose overflow level is above the overflow edge (4) arranged to the washing compartment. Around for example, to avoid the water mask during a blower assisted Drying cycle from the overpressure present in the washing compartment (3) into the second chamber (6) is pressed, the overflow level of the overflow (10) in this embodiment is one several times higher than the highest achievable level of water makeup in the first Chamber (5) formed. Basically, it is sufficient if the overflow (10) just like that high is that a water trap during a controlled flush program run does not flow from the first chamber (5) via the overflow (10) in the second chamber (6).
Liegt eine Wasservorlage im Wasserreservoir (9) vor, so taucht die Flüssigkeitsleitung (8) gemäß der oben beschriebenen Ausführung in das Wasser ein, so dass der Spülraum (3) durch die Wasservorlage von dem in der zweiten Kammer (6) ausgebildeten Ablauf (7) getrennt ist.If there is a water reservoir in the water reservoir (9), the liquid line (8) appears according to the embodiment described above in the water, so that the washing compartment (3) by the water mask is separated from the drain (7) formed in the second chamber (6).
Gemäß der Zeichnung ist die Flüssigkeitsleitung (8) bis weit unterhalb der das Wasserreservoir (9) begrenzenden Überlaufkante (4) geführt, so dass für eine Trennung der vorbeschriebenen Art schon eine geringe bis zur Höhe der Ausgangsöffnung (8.1) der Flüssigkeitsleitung (8) stehende Wasservorlage ausreicht. Die Flüssigkeitsleitung (8) ist nach der Zeichnung durch die an die Gehäuseaußenwand (11) der Spülmaschine (2) anliegende Kammerwand (12) und einer umliegenden Mantelfläche (13) gebildet. Alternativ könnte aber auch ein handelsübliches gebogenes Rohr als Flüssigkeitsleitung (8) dienen.According to the drawing, the liquid line (8) is far below the water reservoir (9) limiting overflow edge (4), so that for a separation of the above Type already a small up to the height of the outlet opening (8.1) of the liquid line (8) standing water template is sufficient. The liquid line (8) is shown in the drawing by the to the housing outer wall (11) of the dishwasher (2) adjacent the chamber wall (12) and a surrounding lateral surface (13) is formed. Alternatively, however, could also be a commercial one bent pipe serve as a liquid line (8).
