Description

Einrichtung zur Zufuhr von Frischwasser in den Spülbehälter einer Geschirrspülmaschine.Device for supplying fresh water into the washing container of a dishwasher.

Die Erfindung bezieht sich auf eine Einrichtung zur Zufuhr von Frischwasser in den Spülbehälter einer Geschirrspülmaschine mit einem im Boden des Spülbehälters angeordneten Steigrohr für die Versorgung eines mit Sprühdüsen versehenen Rotors aus einer Umwälzpumpe.The invention relates to a device for supplying fresh water into the washing container of a dishwasher with a riser pipe arranged in the bottom of the washing container for supplying a rotor provided with spray nozzles from a circulation pump.

Es ist bekannt, das Frischwasser in die Behälter von Geschirrspülmaschinen sowohl über den sogenannten Sumpf des Behälters oder über Entlüftungstaschen an den Seitenwandungen einlaufen zu lassen. Ferner ist es bekannt, z.B. an der Decke Sprühdüsen anzuordnen, durch die bei Zufuhr von Frischwasser schon ein gewisses Abspülen des Geschirrs erreicht wird. Auch die Beschickung von Rotoren und die Anordnung von Sprühdüsen ist zu diesem Zweck bekannt.It is known to let the fresh water run into the containers of dishwashers both via the so-called sump of the container or via ventilation pockets on the side walls. It is also known, e.g. To arrange spray nozzles on the ceiling, through which a certain rinsing of the dishes is achieved when fresh water is supplied. The loading of rotors and the arrangement of spray nozzles is also known for this purpose.

Die zusätzliche Anordnung von starren Sprühdüsen für die Zufuhr von Frischwasser dient meist dazu, die in den Behälterboden eingelassenen Siebe durch einen Sprühstrahl zu reinigen. Diese bekannte Aufbauform erfüllt zwar den Reinigungszweck, macht aber einen zusätzlichen Durchbruch im Behälterboden ebenso notwendig wie das Anbringen eines im Bodenbereich angeordneten Düsenteiles.The additional arrangement of rigid spray nozzles for the supply of fresh water usually serves to clean the sieves embedded in the container bottom by means of a spray jet. This known design fulfills the cleaning purpose, but makes an additional breakthrough in the container bottom as necessary as the attachment of a nozzle part arranged in the bottom area.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur Zufuhr von Frischwasser anzugeben, die einerseits eine gleichmäßige Einbringung des Wassers im Bodenbereich ermöglicht, die insbesondere nach einem Heizvorgang auch geeignet ist, die Heizschlangen abzukühlen, evtl. vorhandenen Schaum zu zerschlagen und die darüber hinaus geeignet ist, auf den Sieben einen gewissen Spüleffekt hervorzurufen, ohne daß zusätzliche Durchbrüche oder Einbauteile, die störend in den Behälterraum ragen können, benötigt werden.The invention has for its object to provide a device for supplying fresh water, which on the one hand enables a uniform introduction of the water in the floor area, which is particularly suitable after a heating process to cool the heating coils, break up any foam and which is also suitable is to produce a certain rinsing effect on the sieves without additional openings or built-in parts which are disruptive protrude into the container space are required.

Die Einrichtung nach der Erfindung ist gekennzeichnet durch einen das Steigrohr zumindest teilweise umschließenden Mantel, der unterhalb des Rotors in einem mit Sprühöffnungen versehenen Kopf endet und mit der Frischwasserzuleitung verbunden ist.The device according to the invention is characterized by a jacket which at least partially surrounds the riser pipe and which ends below the rotor in a head provided with spray openings and is connected to the fresh water supply line.

Vorteilhaft ist es, die Sprühöffnungen am oberen Rand des Mantels einzuformen oder aber den Mantel mit einer Abdeckplatte zu versehen, die das zulaufende Wasser gegen die anzusprühenden Bereiche lenkt.It is advantageous to mold the spray openings at the upper edge of the jacket or to provide the jacket with a cover plate which directs the incoming water against the areas to be sprayed.

Anhand der Zeichnung sei ein Ausführungsbeispiel der Erfindung beschrieben. Zur besseren Übersicht sind alle für das Verständnis nicht notwendigen Teile, wie der Spülbehälter selbst, die Geschirrkörbe und auch die Rotoren mit den Sprühdüsen, weggelassen.An embodiment of the invention will be described with reference to the drawing. For a better overview, all parts that are not necessary for understanding, such as the washing container itself, the crockery baskets and also the rotors with the spray nozzles, have been omitted.

Die Figur zeigt einen Ausschnitt des Geschirrspülers im Schnitt, wie er sich im Bereich des Bodens eines Spülbehälters darstellt. In den Behälterboden ist ein Schacht 1 eingeformt, der eine Pumpe 2 mit dem Laufrad 3 sowie deren Auslaß 4 aufnimmt. An den Auslaß 4 der Pumpe 2 schließt sich ein Steigrohr 5 an, das mit einem nicht gezeichneten unteren Rotor zum Besprühen der Geschirrteile im Spülbehälter verbunden ist. Oberhalb der Pumpe 2 ist eine Schachtabdeckung 6 angeordnet, an die ein Mantel 7 angeformt ist, der das Steigrohr 5 umschließt. Der Mantel 7 steht mit einem an das Gehäuse 14, 15 der Pumpe 2 angeformten Teil 8 in Verbindung, das eine Kammer 9 bildet, in die über eine Zuleitung 10 Frischwasser eingespeist wird.The figure shows a section of the dishwasher in section as it appears in the area of the bottom of a washing container. A shaft 1 is formed in the bottom of the container, which receives a pump 2 with the impeller 3 and its outlet 4. At the outlet 4 of the pump 2 there is a riser pipe 5, which is connected to a lower rotor, not shown, for spraying the dishes in the washing container. Above the pump 2 there is a manhole cover 6, to which a jacket 7 is formed, which surrounds the riser pipe 5. The jacket 7 is connected to a part 8 formed on the housing 14, 15 of the pump 2, which forms a chamber 9 into which fresh water is fed via a feed line 10.

Das Frischwasser steigt entsprechend den eingezeichneten Pfeilen im Bereich zwischen Mantel 7 und Steigrohr 5 auf und tritt aus den öffnungen 11 des Mantels 7 aus. Ein Deckteil 12 schließt nicht nur den Mantel 7 nach oben ab, sondern lenkt auch das austretende Frischwasser gegen die gewünschten Flächenteile, z.B. einen nicht gezeichneten Heizkörper oder ein eingelegtes Sieb 13.The fresh water rises according to the arrows drawn in the area between the jacket 7 and the riser pipe 5 and emerges from the openings 11 of the jacket 7. A cover part 12 not only closes the jacket 7 upwards, but also directs the emerging fresh water against the desired surface parts, for example a radiator (not shown) or an inserted sieve 13.

In der gezeichneten Ausführungsform ist der Mantel 7 Teil der Schachtabdeckung 6. Selbstverständlich kann der Mantel 7 auch als selbständiges Element ausgebildet;an das Steigrohr 5 angeformt sein oder ein Teil des Pumpengehäuses 2 bilden.In the embodiment shown, the jacket 7 is part of the manhole cover 6. Of course, the jacket 7 can also be designed as an independent element, molded onto the riser pipe 5 or forming part of the pump housing 2.
