In FIG 1 ist eine schematische Darstellung einer Sprühvorrichtung 1 einer Geschirrspülmaschine in Draufsicht gezeigt, die einen um eine Drehachse D drehbar gelagerten, zweiflügeligen Sprüharm 2 umfasst. An der Oberseite des Sprüharms 2 sind erste Sprühdüsen 3 verteilt angeordnet, die zum Besprühen von Spülgut dienen. Das Spülgut ist in einem oberhalb des Sprüharms2 befindlichen Geschirrkorb (nicht gezeigt) angeordnet. Zusätzlich sind am Sprüharm 2 zweite Sprühdüsen 4 vorgesehen, die jeweils mittels eines Betätigungselements 5 einstellbar sind. Die Betätigungselemente 5 sind aus einem nicht korrodierbaren Material, zweckmäßigerweise aus Kunststoff, hergestellt. In dem konkreten Ausführungsbeispiel gemäß FIG 1 sind vier zweite Sprühdüsen 4 über die radiale Länge L des Sprüharms 2 derart verteilt angeordnet, dass über die Länge L insgesamt vier radial voneinander beabstandete Spülzonen gebildet sind, in denen das Spülgut bei Bedarf intensiver besprüht werden kann. Die Betätigungselemente 5 dienen zum Öffnen oder Schließen der zweiten Sprühdüsen 4, so dass der Austritt der Spülflüssigkeit aus den zweiten Sprühdüsen 4 gestattet oder verhindert wird und entsprechend die anhand der zweiten Sprühdüsen 4 gebildeten Spülzonen aktiv oder inaktiv sind. Zusätzlich können an der Unterseite des Sprüharms 2 eine oder mehrere zweite Sprühdüsen 4 vorgesehen sein, die ebenfalls mittels Betätigungselementen 5 einstellbar sind. Diese Maßnahme ist insbesondere für Sprüharme 2 vorteilhaft, die in einer oberen Höhenebene im Spülraum der Geschirrspülmaschine angeordnet sind.In Figure 1 is a schematic representation of a spray device 1 shows a dishwasher in top view, which are mounted rotatably about an axis of rotation D, comprises two-wing spray arm 2. At the top of the Spray arms 2, first spray nozzles 3 are distributed, which are used to spray dishes. The wash ware is in a crockery basket located above the spray arm2 (not shown) arranged. In addition, there are 2 second spray nozzles 4 are provided, each by means of a Actuator 5 are adjustable. The actuators 5 are made of a non-corrodible material, expediently made of plastic. In the concrete Embodiment according to FIG 1 are four second Spray nozzles 4 over the radial length L of the spray arm 2 in such a way distributed that over the length L overall formed four radially spaced rinse zones in which the dishes are sprayed more intensively if necessary can be. The actuating elements 5 are used for opening or closing the second spray nozzle 4 so that the outlet the rinsing liquid from the second spray nozzles 4 allowed or is prevented and accordingly based on the of the second spray nozzles 4 active or are inactive. In addition, at the bottom of the Spray arm 2 provided one or more second spray nozzles 4 be, which are also adjustable by means of actuators 5 are. This measure is particularly useful for spray arms 2 advantageous in an upper level in the wash cabinet the dishwasher are arranged.

In den FIG 2, 2a und 2b ist jeweils eine vergrößerte Darstellung eines Betätigungselements 5 in verschiedenen Stellungen relativ zu einer zugeordneten zweiten Sprühdüse 4 gezeigt. Das Betätigungselement 5 umfasst eine etwa plättchenförmige Abdeckung, die am Sprüharm 2 verschiebbar geführt ist, beispielsweise in einer Ausnehmung 7 des Sprüharms 2. Das Betätigungselement 5 weist einen Vorsprung 6 zur Erleichterung der manuellen Betätigung auf. Alternativ kann das Betätigungselement 5 so ausgebildet sein, dass es über entsprechende Wahltasten oder über bestimmte Spülprogramme ansteuerbar ist.2, 2a and 2b each show an enlarged view of an actuator 5 in different positions relative to an assigned second spray nozzle 4 shown. The actuating element 5 comprises an approximately plate-shaped one Cover, which is guided on the spray arm 2 is, for example in a recess 7 of the Spray arm 2. The actuating element 5 has a projection 6 to facilitate manual operation. alternative The actuating element 5 can be designed such that it using the corresponding selection buttons or certain wash programs is controllable.

Wie in FIG 2 gezeigt ist, ist das Betätigungselement 5 in einer ersten Stellung 8 derart relativ zu der zweiten Sprühdüse 4 positioniert, dass die Spülflüssigkeit durch die zweite Sprühdüse 4 vollständig hindurchtreten kann. Durch Verschieben des Betätigungselements 5 in Richtung des Pfeils A zur zweiten Sprühdüse 4 hin gelangt das Betätigungselement 5 in eine zweite Stellung 9 (FIG 2a), in der es die zweite Sprühdüse 4 teilweise überdeckt, so dass lediglich ein teilweiser Austritt von Spülflüssigkeit ermöglicht ist. Durch die Verkleinerung des Querschnitts der zweiten Sprühdüse 4 wird eine Druckerhöhung der Spülflüssigkeit erreicht. Um den Austritt der Spülflüssigkeit aus der zweiten Sprühdüse 4 zu verhindern, wird das Betätigungselement 5 weiter in Richtung des Pfeils A in eine dritte Stellung 10 geschoben, wie in FIG 2b dargestellt ist. In dieser dritten Stellung 10 wird die zweite Sprühdüse 4 vollständig von dem Betätigungselement 5 überdeckt bzw. geschlossen. In Abhängigkeit der Stellungen 8,9 oder 10 der Betätigungselemente 5 kann zusätzlich der Spülflüssigkeitsdruck variiert werden. Sind beispielsweise sämtliche zweiten Sprühdüsen 4 vollständig geschlossen (dritte Stellung 10), so erhöht sich der Druck der aus den ersten Sprühdüsen 3 austretenden Spülflüssigkeit auf ein Maximum. As shown in FIG. 2, the actuating element 5 is in a first position 8 relative to the second Spray nozzle 4 positioned that the rinsing liquid through the second spray nozzle 4 can pass completely through. By moving the actuator 5 in the direction of Arrow A to the second spray nozzle 4 reaches the actuating element 5 in a second position 9 (FIG 2a), in the it partially covers the second spray nozzle 4, so that only a partial leakage of rinsing liquid enables is. By reducing the cross section of the second spray nozzle 4 is an increase in pressure of the rinsing liquid reached. To prevent the rinsing liquid from escaping to prevent the second spray nozzle 4, the actuator 5 continue in the direction of arrow A into a third position 10 pushed, as shown in FIG 2b is. In this third position 10, the second spray nozzle 4 completely covered by the actuating element 5 or closed. Depending on the positions 8.9 or 10 of the actuating elements 5 can additionally the flushing fluid pressure can be varied. Are all, for example second spray nozzles 4 completely closed (third Position 10), the pressure from the first increases Spray nozzles 3 escaping rinsing liquid to a maximum.

Bei teilweise geöffneten zweiten Sprühdüsen 4 (zweite Stellung 9) lässt sich sowohl ein erhöhter Druck als auch eine erhöhte Menge der austretenden Spülflüssigkeit erzielen. Sind die zweiten Sprühdüsen beispielsweise vollständig geöffnet (erste Stellung 8), so tritt die maximale Menge an Spülflüssigkeit bei vergleichsweise niedrigerem Druck aus, so dass sowohl eine schonende als auch eine intensive Reinigung des Spülguts gewährleistet ist.With the second spray nozzles 4 partially open (second position 9) can both an increased pressure and a achieve an increased amount of escaping flushing liquid. For example, are the second spray nozzles completely open? (first position 8), the maximum quantity appears Flushing liquid at comparatively lower pressure, so that both a gentle and an intensive cleaning of the wash ware is guaranteed.

Die Betätigungselemente 5 können zusätzlich Rastmittel (nicht gezeigt) aufweisen, die mit korrespondierenden Rastmitteln am Sprüharm 2 in Eingriff gelangen, so dass die Betätigungselemente 5 in den oben beschriebenen drei Stellungen 8, 9 und 10 verrastbar sind.The actuating elements 5 can additionally latch means (not shown), which with corresponding locking means engage on the spray arm 2 so that the actuating elements 5 in the three positions described above 8, 9 and 10 can be locked.

Alternativ können anstelle der verschiebbar angeordneten Betätigungselemente 5 drehbar oder schwenkbar ausgebildete Betätigungselemente vorgesehen sein, die durch Drehen oder Schwenken die zweiten Sprühdüsen 4 zumindest teilweise öffnen oder schließen.Alternatively, instead of being slidably arranged Actuators 5 designed to be rotatable or pivotable Actuators can be provided by turning or Swing the second spray nozzles 4 open at least partially or close.

Da jeder zweiten Sprühdüse 4 jeweils ein bewegbares Betätigungselement 5 zugeordnet ist, sind die zweiten Sprühdüsen 4 individuell bzw. unabhängig voneinander einstellbar. Der Benutzer hat somit eine Vielzahl von Variationsmöglichkeiten zur Verfügung, um je nach Menge, Verteilung und/oder Verschmutzungsgrad des Spülguts das Besprühen des Spülguts flexibel zu gestalten. Anhand der einstellbaren zweiten Sprühdüsen 4 lassen sich die Menge, die Richtung bzw. die Spülzonen und/oder der Druck der austretenden Spülflüssigkeit optimal an den Beladungszustand anpassen. Since every second spray nozzle 4 each has a movable actuating element 5 is assigned, are the second spray nozzles 4 individually or independently adjustable. The User thus has a variety of variation options available to according to quantity, distribution and / or Degree of soiling of the wash ware the spraying of the wash ware to be flexible. Using the adjustable second Spray nozzles 4 can be the amount, the direction or the Rinsing zones and / or the pressure of the escaping rinsing liquid adapt optimally to the loading condition.
