Description

Die Erfindung bezieht sich auf eine Spülmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a dishwasher according to the preamble of claim 1.

Bei derartigen Maschinen fallen alkalihaltige Tropfen der Spüllauge von den Flächen, wie z. B. der Haubendecke, von dem oberen horizontalen Ausleger, der die Lagerung für einen rotierenden Spülarm trägt und von dem rotierenden Spülarm nach Abschluß des Spülprogramms auf das mit dem Spülprogramm gereinigte Geschirr in der Zeit vom Ende des Spülprogramms bis zur Entfernung des Geschirrs aus dem Spülraum.In such machines, alkaline drops of the rinse water fall off the surfaces, such as. B. the hood ceiling, of the upper horizontal arm, which carries the storage for a rotating wash arm and of the rotating wash arm after completion of the wash program on the dishes cleaned with the wash program in the period from the end of the wash program to the removal of the dishes from the wash cabinet .

Diese Tropfen trocknen auf dem Geschirr ab. Sie sind optisch unschön und vermitteln dem Benutzer des Geschirrs den Eindruck mangelnder Hygiene.These drops dry on the dishes. They are visually unattractive and give the user of the dishes the impression of poor hygiene.

Zur Beseitigung dieses Mangels müssen die Geschirrteile einzeln von Hand nachgearbeitet werden, bevor die Tropfen antrocknen.To remedy this deficiency, the dishes must be reworked individually by hand before the drops dry.

Aufgabe der Erfindung ist es, eine Spülmaschine nach dem Oberbegriff des Anspruchs 1 so zu gestalten, daß keine oder zumindest weniger alkalihaltige Tropfen der Spüllauge auf das schon gereinigte Geschirr fallen können.The object of the invention is to design a dishwasher according to the preamble of claim 1 so that no or at least fewer alkali-containing drops of the washing-up liquid can fall onto the already cleaned dishes.

Gelöst wird diese Aufgabe mit einer Anordnung der abtropfenden Flächen einer Spülmaschine nach dem kennzeichnenden Teil des Anspruchs 1 und der übrigen Ansprüche.This object is achieved with an arrangement of the dripping surfaces of a dishwasher according to the characterizing part of claim 1 and the other claims.

Die Vorteile der Erfindung wurden durch wirklichkeitsnahe Versuche gemessen, indem die während des üblichen Zeitraumes vom Abschluß des Spülprogramms bis zur Entfernung des Geschirrs aus dem Spülraum auf das Geschirr fallenden Tropfen alkalihaltiger Spüllauge gezählt wurden.The advantages of the invention were measured by realistic tests by counting the drops of alkali-containing washing liquor falling on the dishes during the usual period from the completion of the washing program to the removal of the dishes from the washing compartment.

Bei einer Spülmaschine nach dem Stand der Technik mit horizontalen Flächen waren dies ca. 50 Tropfen.In the case of a dishwasher according to the prior art with horizontal surfaces, this was approximately 50 drops.

Bei einer gleichen Maschine mit etwa 3° von der Horizontalebene abweichenden schräg angeordneten Flächen waren dies ca. 10 Tropfen.In the same machine with obliquely arranged surfaces deviating approximately 3 ° from the horizontal plane, this was approximately 10 drops.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.

Beschreibung zur Patentanmeldung Nr. 2 Spülmaschine, insbesondere für GeschirrteileDescription of patent application no. 2 dishwasher, in particular for dishes

Die Haube 1 einer Spülmaschine ist mittels eines einerseits am Gehäuse der Spülmaschine gelagerten Bügels 6 der andererseits gelenkig mit den Seitenwänden der Haube 1 verbunden ist höhenverstellbar. Die innere Decke 2 der Haube 1 ist von der Horizontalebene abweichend in Pfeilrichtung 8 nach vorne schräg abfallend ausgeführt. Der Pfeil 11 zeigt an, welches als Vorderseite der Spülmaschine verstanden wird. Die an den beiden Seitenwänden der Haube 1 unten angeordneten Tropfrinnen 3 sind von der Horizontalebene abweichend schräg nach unten in Pfeilrichtung 9 fallend angeordnet. Von der Haubendecke 2 abfließende Flüssigkeit kann an der Vorderwand der Haube 1 herunterfließen in die umlaufende Tropfrinne. Die von den Seitenwänden der Haube 1 abfließende Flüssigkeit kann ebenfalls in die umlaufende Tropfrinne fließen. Über die Tropfrinne 3 wird diese Flüssigkeit dann unschädlich nach hinten in die Spülmaschine abgeleitet. Die Decke 2 der Haube 1 kann außer in Pfeilrichtung 8 auch in Richtung aller vier Begrenzungswände von der Mitte ausgehend geneigt sein. Ein oberer horizontaler Ausleger 4 ist von der Horizontalebene abweichend in Pfeilrichtung 10 schräg nach unten geneigt angeordnet. Am horizontalen Ausleger 4 ist eine Achse 12 befestigt, an der ein oberer rotierender Spülarm 5 gelagert ist. Der Ausleger 4 dient gleichzeitig als Spüllaugezuführungsrohr für den oberen Ausleger 5. Bei rechtwinkliger Befestigung der Achse 12 am Ausleger 4 ist der obere rotierende Spülarm 5 damit zwangsläufig auch in die gleiche Schräglage wie der obere Ausleger 4 gebracht. Nach Abschluß des Spülprogramms kann das, sich im oberen Ausleger 4 dem Zuleitungsrohr für den oberen Spülarm 5 befindende, Spülwasser nach hinten in die Maschine abfließen. Die Spüllauge fließt somit nicht mehr in den Spülarm und tropft über diesen damit auch nicht mehr aus auf die Geschirrteile 7. Die sich im oberen rotierenden Spülarm 5 befindende Spüllauge kann auch nicht mehr beliebig über die Geschirrteile 7 austropfen, sondern fließt auf eine mit Position 13 bezeichnete Tropffläche außerhalb des Bereichs der Geschirrteile 7 im hinteren Teil des Inneren der Spülmaschine unschädlich ab. Um sicherzustellen, daß der obere rotierende Spülarm 5 in der in Figur 1 dargestellten Position stehenbleibt nach Abschluß des Spülprogramms, ist in einem Ausführungsbeispiel eine Rotationsunwucht 14 am oberen rotierenden Spülarm 5 vorgesehen. Die Rotationsunwucht 14 am oberen Spülarm 5 bewirkt, daß das schwerere Ende des oberen rotierenden Spülarms 5 aus physikalischen Gründen immer an der tiefsten Stelle der Rotationsebene des oberen rotierenden Spülarms 5 stehenbleibt. Diese tiefste Stelle ist konstruktiv so gelegt, daß sie außerhalb der zu spülenden Geschirrteile 7 liegt. An dieser tiefsten Stelle fließt nach Stillstand des oberen rotierenden Spülarms 5 nach Abschluß des Spülprogramms die sich im Spülarm 5 befindende Spüllauge unschädlich ab.The hood 1 of a dishwasher can be adjusted in height by means of a bracket 6, which is mounted on the housing of the dishwasher on the one hand and is articulated on the other hand to the side walls of the hood 1. The inner ceiling 2 of the hood 1 is designed to slope away from the horizontal plane in the direction of the arrow 8. The arrow 11 indicates which is understood as the front of the dishwasher. The drip trays 3 arranged at the bottom on the two side walls of the hood 1 are arranged so as to deviate obliquely downward in the direction of the arrow 9 from the horizontal plane. Liquid flowing out of the hood ceiling 2 can flow down the front wall of the hood 1 into the peripheral drip channel. The liquid flowing off the side walls of the hood 1 can also flow into the peripheral drip channel. This liquid is then discharged harmlessly backwards into the dishwasher via the drip channel 3. The ceiling 2 of the hood 1 can also be inclined in the direction of the arrow 8 in the direction of all four boundary walls starting from the center. An upper horizontal boom 4 is arranged to be inclined downwards in the direction of arrow 10, deviating from the horizontal plane. On the horizontal boom 4, an axis 12 is attached, on which an upper rotating flush arm 5 is mounted. The arm 4 also serves as a washing solution feed pipe for the upper arm 5. When the axis 12 is attached to the arm 4 at right angles, the upper rotating arm 5 is thus necessarily also brought into the same inclined position as the upper arm 4. After the washing program has ended, the washing water located in the upper arm 4 of the feed pipe for the upper washing arm 5 can flow back into the machine. The soapy water does not flow more into the rinse arm and therefore no longer drips out onto the crockery parts 7. The rinsing liquor located in the upper rotating rinse arm 5 can no longer drip over the crockery parts 7 as desired, but instead flows to a drip area designated with position 13 outside the area the dishes 7 in the rear part of the interior of the dishwasher harmless. In order to ensure that the upper rotating washing arm 5 remains in the position shown in FIG. 1 after the washing program has been completed, a rotational imbalance 14 is provided on the upper rotating washing arm 5. The rotational unbalance 14 on the upper washing arm 5 causes the heavier end of the upper rotating washing arm 5 to always remain at the lowest point on the plane of rotation of the upper rotating washing arm 5 for physical reasons. This lowest point is structurally placed so that it lies outside the dishes 7 to be washed. At this lowest point, after the upper rotating wash arm 5 has come to a standstill, after the wash program has ended, the wash liquor located in the wash arm 5 flows away harmlessly.
