Abstract

In dishwashing machines having a plurality of spraying arms, it is advantageous for the individual spraying arms to be loaded with washing water alternately and successively. However, this should take place with a smooth transition in order to avoid pressure surges. This purpose is served by a switchover device which consists of a hollow cylinder constructed in sectors, which rotates in a can-shaped housing. While the washing water is being supplied via a central inlet nozzle (3) in the can housing, the hollow cylinder slides over the inside surface of the circumference of the housing and exposes the outlet nozzles (4, 5) alternately. <IMAGE>

Description

Umschaltvorrichtung für eine Geschirrspülmaschine Switching device for a dishwasher

Die Erfindung betrifft eine Umschaltvorrichtung für abwechselnd nacheinander an eine Umwälzpumpe anschließbare Sprüharme einer Geschirrspülmaschine.The invention relates to a switching device for alternately one after the other Spray arms of a dishwasher that can be connected to a circulation pump.

Bei Geschirrspülmaschinen ist es üblich, die im Spülbehälter angeordneten Geschirrkörbe über Sprüharme mit dem Spülwasser zu beaufschlagen. Es hat sich als zweckmäßig erwiesen diese Sprüharme nicht alle gleichzeitig an die Umwälzpumpe anzuschließen, sondern abwechselnd nacheinander, wie es in der FR-PS 1 233 812 beschrieben ist. Auf diese Weise kann der Wasserverbrauch vermindert werden und es genügt eine Umwälzpumpe geringerer Leistung.In dishwashers, it is common to use those arranged in the washing compartment To apply washing water to crockery baskets via spray arms. It turned out to be It has proven to be useful not to connect all of these spray arms to the circulation pump at the same time, but alternately one after the other, as described in FR-PS 1,233,812. In this way, the water consumption can be reduced and a circulation pump is sufficient lower performance.

Umstellklappen oder Ventile sind mechanisch auf Dauer anfällig und die Umschaltung des Wasserweges sollte möglichst stoßfrei geschehen. Zur Lösung dieser Aufgabe wird erfindungsgemäß als Umschaltvorrichtung ein dosenartiges Gehäuse vorgeschlagen, in dessen Gehäuseboden zentral der Zulaufstutzen mündet und an dessen Gehäuseumfang die Ablaufstutzen abzweigen. Im Gehäuse rotiert ein sektorförmiges Steuerorgan, welches über die Innenfläche des Gehäuseumfanges gleitet.Diverter flaps or valves are mechanically susceptible in the long term and the switchover of the waterway should be as smooth as possible. To the solution this object is a can-like housing as a switching device according to the invention proposed, in the housing bottom of the inlet port opens centrally and at its Branch off the drainage pipe around the circumference of the housing. A sector-shaped one rotates in the housing Control element, which slides over the inner surface of the housing circumference.

Eine solche Umschaltvorrichtung arbeitet stetig und die Ablaufstutzen werden nacheinander stetig geöffnet bzw. geschlossen, so daß eine stoßfreie Umschaltung ermöglicht wird.Such a switching device works continuously and the drainage nozzle are continuously opened or closed one after the other, so that a bumpless changeover is made possible.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen: Fig. 1 die Draufsicht einer Umschaltvorrichtung Fig. 2 den Längsschnitt entsprechend II-II.An exemplary embodiment of the invention is shown in the drawing. Show it: Fig. 1 is a plan view of a switching device. 2 the longitudinal section according to II-II.

Das dosenförmige Gehäuse 1 der Umschaltvorrichtung besitzt im Gehäuseboden 2 zentral den Zulaufstutzen 3, an welchen die von der Umwälzpumpe kommende Druckwasserleitung anschließbar ist.The can-shaped housing 1 of the switching device has in the housing bottom 2 centrally the inlet connection 3, to which the pressurized water line coming from the circulation pump is connectable.

Am Umfang des Gehäuses 1 zweigen die beiden einander gegenüberliegenden Ablaufstutzen 4 und 5 ab. An den einen Ablaufstutzen 4 kann beispielsweise ein unterhalb des Geschirrkorbes angeordneter Sprüharm und an den anderen 5 ein oberhalb des Geschirrkorbes angeordneter Sprüharin angeschlossen werden. Innerhalb des Gehäuses 1 befindet sich das über die Achse 6 rotierend antreibbare sektorförmige Steuerorgan 7. Die schaufelartig ausgebildete Wand des Steuerorganes besteht aus dem Segmentteil 8, an welchem die Antriebsachse 6 angreift, dem über die Innenfläche des Gehäuseumfanges gleitenden Krümmung steil 9 und dem segmentartigen Lagerteil 10, welcher eine Durchbrechung 11 aufweist.On the circumference of the housing 1, the two opposite one another branch Drain nozzles 4 and 5. At the one outlet connection 4, for example, a below the crockery basket arranged spray arm and on the other 5 one above the crockery basket arranged sprayer can be connected. Inside the housing 1 is located the sector-shaped control member 7 which can be driven in rotation via the axis 6 trained wall of the control member consists of the segment part 8 on which the Drive shaft 6 engages, the sliding over the inner surface of the housing circumference Curvature steep 9 and the segment-like bearing part 10, which has an opening 11 has.

Das rotierende Steuerorgan 7 verschließt und öffnet abwechselnd die Ablaufstutzen 4 und 5, so daß die angeschlossenen Sprüharme abwechselnd mit Druckwasser beaufschlagt werden. Wie die Pfeile in Fig. 2 andeuten, ist in dieser Stellung der Ablaufstutzen 4 verschlossen und der Ablaufstutzen 5 ist freigegeben. Über die Rotationsgeschwindigkeit des Steuerorgans 7 kann der Takt der Öffnungs- bzw. Schließzeiten variiert werden.The rotating control member 7 closes and opens alternately the Drain connection 4 and 5, so that the connected spray arms alternate with pressurized water be applied. As the arrows in Fig. 2 indicate, is in this position Drain connection 4 closed and the drain connection 5 is released. About the speed of rotation of the control member 7, the cycle of the opening and closing times can be varied.

Die Lagerachse 6 ist durch den Gehäusedeckel 12 geführt und in diesem gelagert. Mit der einfachen Umschaltvorrichtung ist eine betriebssichere Steuerung ohne Wasserstöße möglich.The bearing axis 6 is guided through the housing cover 12 and in this stored. With the simple switching device is an operationally reliable control possible without water rushes.
