Description

Die Erfindung betrifft eine Geschirrspülmaschine mit einem oder mehreren Spülbehältern und einer Vorrichtung zum Besprühen von im Spülbehälter angeordnetem Spülgut.The invention relates to a dishwasher with one or more washing containers and a device for spraying arranged in the washing container items.

Es sind Geschirrspülmaschinen mit Sprüheinrichtungen bekannt, die mit rotierenden Sprüharmen arbeiten. Da in den herkömmlichen Geschirrspülmaschinen der Spülbehälter üblicherweise einen rechteckigen Grundriss aufweist, während die rotierenden Sprüharme einen kreisförmigen Wirkungsbereich haben, können die jeweiligen Eckenbereiche durch die rotierenden Sprüharme nur unzulänglich mit Spülflüssigkeit besprüht werden. Darüber hinaus haben rotierende Sprüharme den Nachteil, dass es sich um bewegte Teile handelt, die sowohl dem bewegungsbedingten Verschleiß als auch einer erhöhten Störanfälligkeit unterliegen, wenn beispielsweise in den Bewegungsbereich des Sprüharms geratenes Spülgut die Rotation des Sprüharms behindern.There are dishwashers with sprayers are known to work with rotating spray arms. Since in conventional dishwashers the rinsing container usually has a rectangular outline, while the rotating spray arms have a circular area of action, the respective corner areas can only be insufficiently sprayed with rinsing liquid by the rotating spray arms. In addition, rotating spray arms have the disadvantage that they are moving parts, which are subject to both the movement-related wear and an increased susceptibility to interference when, for example, in the range of movement of the spray arm advised washware hinder the rotation of the spray arm.

Ferner sind im Stand der Technik Sprüheinrichtungen bekannt, die über sogenannte Sprühböden das darüber befindliche Spülgut mit Spülflüssigkeit beaufschlagen. Als nachteilig hat sich bei diesen Sprüheinrichtungen erwiesen, dass die aus den Sprühböden austretenden Sprühstrahlen vorbestimmte Richtungen haben, so dass eine gleichmäßige Reinigungsleistung des Spülguts nicht gewährleistet bzw. das vom Sprühboden erzeugte Sprühmuster nicht auf unterschiedliche Arten von Spülgut angepasst werden kann.Furthermore, spraying devices are known in the prior art, which act on so-called spray floors the washware located above it with rinsing liquid. It has proved to be disadvantageous in these spraying devices that the sprays emerging from the spraying trays have predetermined directions, so that a uniform cleaning performance of the items to be washed is not guaranteed or the spray pattern generated by the spraying floor can not be adapted to different types of items to be washed.

Es sind auch Geschirrspülmaschinen mit Sprüheinrichtungen bekannt, bei denen über eine feststehende Sprühdüse oder Sprühbrause, die an der Rückwand des Spülbehälters angeordnet ist, das im Spülbehälter befindliche Spülgut mit Spülflüssigkeit beaufschlagt wird. Solche Sprüheinrichtungen haben den Nachteil, dass sie von der Rückwand in den Innenraum des Spülbehälters hineinragen und damit den für die Anordnung von Spülgut nutzbaren Raum im Spülbehälter verringern. Ferner entwickeln die bekannten Sprüheinrichtung nur gleichbleibende Sprühstrahlen, was für die Reinigungswirkung des Spülguts nachteilig ist.There are also dishwashing machines with spray devices are known in which via a fixed spray nozzle or spray shower, which is arranged on the rear wall of the washing container, the washware located in the washing container is supplied with washing liquid. Such spraying devices have the disadvantage that they protrude from the rear wall into the interior of the washing container and thus reduce the usable space for the arrangement of dishes in the washing compartment. Furthermore, the known spraying develop only constant spray, which is detrimental to the cleaning effect of the dishes.

Aus der DE 200 07 044 U1 ist eine Reinigungsvorrichtung bekannt, bei welcher die Behälterinnenwände mit einer Vielzahl von Sprühöffnungen versehen sind.From the DE 200 07 044 U1 a cleaning device is known in which the container inner walls are provided with a plurality of spray openings.

Die US 3,777,989 beschreibt eine Geschirrspülmaschine mit einer Sprühdüse, die durch einen in einer Bodenwandung eines Spülbehälters angeordneten Kanal gebildet wird und durch eine Abdeckplatte mit einer Mehrzahl von Sprühöffnungen abgedeckt ist.The US 3,777,989 describes a dishwasher with a spray nozzle, which is formed by a channel disposed in a bottom wall of a washing container and is covered by a cover plate having a plurality of spray openings.

Die FR 1 233 812 beschreibt eine Geschirrspülmaschine mit feststehenden Sprühdüsen, die Sprühstrahlen gemäß einer festgelegten zeitlichen Abfolge versprühen.The FR 1 233 812 describes a dishwasher with fixed spray nozzles that spray sprays according to a fixed time sequence.

Die DE 14 03 670 beschreibt eine Geschirrspülmaschine mit Sprühdüsen, die Sprühstrahlen mit einstell- oder umschaltbarer Intensität aussenden. Dabei kann zum Zweck der zeitweisen Erhöhung der Intensität der Flüssigkeitsbesprühung die Zahl der benutzten Sprühdüsen einstellbar verringert werden.The DE 14 03 670 describes a dishwasher with spray nozzles that emit spray with adjustable or switchable intensity. In this case, for the purpose of temporarily increasing the intensity of the Flüssigkeitsbesprühung the number of spray nozzles used can be reduced adjustable.

Die FR 2 766 350 beschreibt eine Geschirrspülmaschine mit mindestens einer Sprüheinrichtung, die austauschbar ist, um die Geschirrspülmaschine für die Reinigung unterschiedlicher Spülgüter zu adaptieren.The FR 2 766 350 describes a dishwasher with at least one sprayer that is interchangeable to adapt the dishwasher for cleaning different items to be washed.

Die EP 0 858 768 beschreibt eine Geschirrspülmaschine mit einer in einer Deckenwandung eines Spülbehälters angeordneten Sprühdüse.The EP 0 858 768 describes a dishwasher with a spray nozzle arranged in a top wall of a washing container.

Aufgabe der vorliegenden Erfindung ist es, eine Geschirrspülmaschine mit einer platzsparenden Vorrichtung zum Besprühen von Spülgut bereitzustellen, bei der die Spülflüssigkeit möglichst gleichmäßig im Spülbehälter eingesprüht wird, um das Spülgut effizient mit Spülflüssigkeit zu beaufschlagen, und der durch bewegte Teile bedingte Verschleiß sowie die Störanfälligkeit beseitigt wird. Eine weitere Aufgabe der vorliegenden Erfindung besteht darin, das von der Sprüheinrichtung erzeugte Sprühmuster auf unterschiedliche Arten von Spülgut anzupassen.Object of the present invention is to provide a dishwasher with a space-saving device for spraying ware, in which the rinsing liquid is sprayed as evenly as possible in the washing to flush the wash ware efficiently, and eliminates the conditional by moving parts wear and susceptibility becomes. Another object of the present invention is to adapt the spray pattern generated by the sprayer to different types of items to be washed.

Diese Aufgabe wird durch die erfindungsgemäße Vorrichtung mit den Merkmalen gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der vorliegenden Erfindung sind in den Unteransprüchen 2 bis 11 gekennzeichnet.This object is achieved by the device according to the invention with the features of claim 1. Advantageous developments of the present invention are characterized in the subclaims 2 to 11.

Der erfindungsgemäße Geschirrspüler umfasst mindestens einen Spülbehälter zur Aufnahme von zu reinigendem Spülgut und eine Sprüheinrichtung zur Beaufschlagung des Spülguts mit Spülflüssigkeit, wobei die Sprüheinrichtung eine Anzahl feststehender Sprühdüsen aufweist, die im Boden-, Decken- und/oder Wandbereich des Spülbehälters angeordnet sind und auf einer zum Innenraum des Spülbehälters gerichteten Seite mindestens eine Öffnung für den Durchtritt der Spülflüssigkeit aufweisen.The dishwasher according to the invention comprises at least one rinsing container for receiving items to be cleaned and a spraying device for loading the items to be washed with rinsing liquid, wherein the spraying device has a number of fixed spray nozzles which are arranged in the bottom, ceiling and / or wall region of the rinsing container and on one to the interior of the washing container directed side have at least one opening for the passage of the washing liquid.

Die Geschirrspülmaschine mit einer Sprüheinrichtung gemäß der Erfindung hat den Vorteil, dass durch die Beaufschlagung des Spülguts mit Spülflüssigkeit aus einer Anzahl von feststehenden Sprühdüsen auf die Anordnung von rotierenden Sprüharmen verzichtet werden kann. Dadurch weist die Sprüheinrichtung keine bewegten Teile mehr auf, was sowohl einen bewegungsbedingten Verschleiß als auch die Störanfälligkeit verringert. Ferner kann auch kein in den Bewegungsbereich eines Sprüharms geratenes Spülgut die Funktion der Sprüheinrichtung behindern. Ein weiterer Vorteil der erfindungsgemäßen Geschirrspülmaschine besteht darin, dass die aus der Anzahl von feststehenden Sprühdüsen austretenden Sprühstrahlen eine gleichmäßige Verteilung der Spülflüssigkeit im Spülbehälter und damit eine gleichmäßige Reinigungsleistung gewährleisten.The dishwasher with a spraying device according to the invention has the advantage that can be dispensed with by applying the wash ware with rinsing liquid from a number of fixed spray nozzles on the arrangement of rotating spray arms. As a result, the spraying device no longer has any moving parts, which reduces both wear due to movement and the susceptibility to interference. Furthermore, even in the range of movement of a Sprüharms washed items can hinder the function of the sprayer. Another advantage of the dishwasher according to the invention is that the spray jets emerging from the number of fixed spray nozzles ensure a uniform distribution of the rinsing liquid in the rinsing container and thus a uniform cleaning performance.

Durch den Wegfall der Notwendigkeit von rotierenden Sprüharmen ergibt sich ferner der Vorteil, dass der zur Anordnung von Spülgut nutzbare Raum im Spülbehälter vergrößert wird. Die Geschirrteile können äußerst nahe am Boden-, Decken- oder Wandbereich des Spülbehälters angeordnet werden, da kein Bewegungsfreiraum für einen rotierenden Sprüharm mehr berücksichtigt werden muss. Darüber hinaus ist auch die Freiheit bei der Gestaltung der im Spülbehälter befindlichen Geschirrkörbe größer, da keine rotierenden Sprüharme oder aus den Boden-, Decken- oder Wandbereichen des Spülbehälters hervorstehende Komponenten zur Verteilung der Spülflüssigkeit zu berücksichtigen sind. Der Wegfall rotierender Sprüharme bringt ebenso eine Verringerung der Geräuschentwicklung während des Betriebs der Geschirrspülmaschine mit sich, da keine starken Antriebsstrahlen mehr erforderlich sind, um den rotierenden Sprüharm in Rotation zu versetzen, die durch den Aufprall auf Boden und Wände des Spülbehälters bislang eine starke Geräuschquelle dargestellt haben.By eliminating the need for rotating spray arms, there is also the advantage that the usable space for the arrangement of items to be washed in the washing is increased. The crockery parts can be placed extremely close to the bottom, ceiling or wall area of the washing container, since no more freedom of movement for a rotating spray arm has to be taken into account. In addition, the freedom in the design of the dish racks located in the rinsing container is greater, since no rotating spray arms or from the bottom, ceiling or wall portions of the rinse tank protruding components are to be considered for the distribution of the rinsing liquid. The elimination of rotary spray arms also entails a reduction in noise during operation of the dishwasher, since no strong drive jets are required to rotate the rotating spray arm, which has heretofore been a source of heavy noise due to the impact on the floor and walls of the washing compartment to have.

Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Geschirrspülmaschine ist eine Anzahl von feststehenden Sprühdüsen im Bodenbereich des Spülbehälters angeordnet. Auf diese Weise kann größeres Spülgut, wie z.B. Pfannen oder Töpfe, die in der Regel im unteren Bereich des Spülbehälters untergebracht sind und meist stärkere Verunreinigungen aufweisen, über die feststehenden Sprühdüsen im Bodenbereich des Spülbehälters einer besonders intensiven Beaufschlagung mit Spülflüssigkeit unterzogen werden.In a preferred embodiment of the dishwasher according to the invention, a number of fixed spray nozzles in the bottom region of the washing compartment arranged. In this way, larger items to be washed, such as pans or pots, which are usually housed in the lower part of the washing and usually have stronger impurities are subjected to the stationary spray nozzles in the bottom portion of the washing a particularly intense application of rinsing liquid.

Dabei ist es besonders vorteilhaft, wenn in den Eckbereichen des Spülbehälters mindestens eine feststehende Sprühdüse angeordnet ist. Dadurch kann bei Spülbehältern mit rechteckigem Grundriss eine gleichmäßige Verteilung der eingesprühten Spülflüssigkeit bis in die Eckbereiche des Spülbehälters erzielt werden, was die Reinigungsleistung der Geschirrspülmaschine verbessert. Ferner muss Länge und Breite des Spülbehälters nicht mehr zwingend in einem Verhältnis von 1:1 ausgebildet sein, wie das beispielsweise bei einer Sprüheinrichtung mit rotierenden Sprüharmen erforderlich ist, sondern kann in nahezu beliebiger Form gestaltet werden, da die Verteilung der feststehenden Sprühdüsen im Boden-, Decken- und/oder Wandbereich des Spülbehälters jeder Form des Spülbehälters entsprechend angepasst werden können.It is particularly advantageous if at least one fixed spray nozzle is arranged in the corner regions of the washing compartment. As a result, a uniform distribution of the sprayed rinsing liquid into the corner regions of the rinsing container can be achieved in rinse containers with a rectangular outline, which improves the cleaning performance of the dishwasher. Furthermore, the length and width of the washing container need not necessarily be formed in a ratio of 1: 1, as is required, for example, in a spraying device with rotating spray arms, but can be designed in almost any desired form, since the distribution of the fixed spray nozzles in the floor , Ceiling and / or wall area of the washing container of each form of the washing container can be adjusted accordingly.

Bei der erfindungsgemäßen Geschirrspülmaschine umfasst die Sprüheinrichtung eine Anzahl von feststehenden Sprühdüsen, denen abwechselnd einzeln oder gruppenweise Spülflüssigkeit zugeführt wird. Durch die abwechselnde Zufuhr von Spülflüssigkeit zu einzelnen Sprühdüsen oder zu einer Gruppe zusammengefassten Sprühdüsen kann einerseits die Reinigungsleistung verbessert werden; andererseits wird durch eine Verringerung der Anzahl von Sprühdüsen, denen gleichzeitig Spülflüssigkeit zugeführt wird, der Druck der aus den Sprühdüsen austretenden Spülflüssigkeitsstrahlen erhöht. Die Spülflüssigkeit wird der Sprüheinrichtung üblicherweise über eine Umwälzpumpe zugeführt. Wenn nur eine kleine Anzahl von Sprühdüsen gleichzeitig mit Spülflüssigkeit versorgt werden muss, kann auch die Dimensionierung bzw. die Pumpleistung der Umwälzpumpe entsprechend klein gehalten werden, was die Kosten für die Umwälzpumpe und damit die Herstellungskosten der Geschirrspülmaschine insgesamt verringert.In the dishwasher according to the invention, the spraying device comprises a number of fixed spray nozzles to which washing liquid is fed alternately, individually or in groups. On the one hand, the cleaning performance can be improved by the alternating supply of rinsing liquid to individual spray nozzles or spray nozzles combined to form a group; On the other hand, by reducing the number of spray nozzles to which flushing liquid is simultaneously supplied, the pressure of the flushing liquid jets emerging from the spray nozzles is increased. The rinsing liquid is usually supplied to the spraying device via a circulating pump. If only a small number of spray nozzles must be supplied with rinsing liquid at the same time, the sizing or the pumping power of the circulation pump can be kept correspondingly small, which reduces the cost of the circulation pump and thus the manufacturing cost of the dishwasher as a whole.

Es hat sich herausgestellt, dass die Reinigungsleistung der Geschirrspülmaschine weiter gesteigert werden kann, wenn der Druck, mit dem die Spülflüssigkeit von der Umwälzpumpe den feststehenden Sprühdüsen zugeführt wird, variierbar ist. Die Zufuhr von Spülflüssigkeit zum Sprühkanal mit zeitlich variierbarem Druck ermöglicht das Erzeugen von Sprühmustern, das auf bestimmte Arten von Spülgut angepasst werden kann. Es können beispielsweise intermittierende, pulsartige oder auf- und abschwellende Spülflüssigkeitsstrahlen erzeugt werden. In bestimmten Abschnitten des Reinigungsvorgangs können stärkere Spülflüssigkeitsstrahlen erforderlich sein, wie z.B. in der Hauptreinigungsphase, während bei anderen Abschnitten des Reinigungsvorgangs schwächerer Spülflüssigkeitsstrahlen erwünscht sind, wie z.B. in der Klarspülphase.It has been found that the cleaning performance of the dishwasher can be further increased if the pressure with which the rinsing liquid from the circulation pump is supplied to the fixed spray nozzles, is variable. The feed from rinsing liquid to the spray channel with time varying pressure allows the production of spray patterns, which can be adapted to certain types of items to be washed. For example, intermittent, pulse-like or swelling-liquid rinse-up rays may be generated. In certain portions of the cleaning process, stronger rinse liquid jets may be required, such as in the main cleaning phase, while in other portions of the cleaning process, weaker rinse liquid jets are desired, such as in the final rinse phase.

Die Variation des Drucks, mit dem die Spülflüssigkeit dem Sprühkanal zugeführt wird, kann durch eine Druckverteilung mit elektronischen, hydraulischen oder mechanischen Mitteln gesteuert werden. Die Verwendung einer elektronisch gesteuerten Druckverteilung hat den Vorteil, dass keine rotierenden oder beweglichen Komponenten erforderlich sind, da sowohl die Intensität als auch das Sprühmuster der Spülflüssigkeitsstrahlen über einen elektronisch kontrollierten Druckablauf und Drucksteuerung vorgenommen wird. Dabei kann entsprechend einer Spülprogrammwahl eine Vielzahl von unterschiedlichen Sprühmustern erzeugt werden. Bei der Auswahl der Sprühmuster ist es möglich, die unterschiedlichen Verschmutzungszustände und die Art des Spülguts zu berücksichtigen.The variation of the pressure with which the rinsing liquid is supplied to the spray channel can be controlled by a pressure distribution with electronic, hydraulic or mechanical means. The use of an electronically controlled pressure distribution has the advantage that no rotating or moving components are required because both the intensity and the spray pattern of the rinse liquid jets are made via an electronically controlled pressure drain and pressure control. In this case, a plurality of different spray patterns can be generated in accordance with a wash program selection. When selecting the spray patterns, it is possible to take into account the different soiling conditions and the type of items to be washed.

Besonders vorteilhaft ist es, dass die feststehenden Sprühdüsen im Boden-, Decken- und/oder Wandbereich des Spülbehälters manuell lösbar bzw. austauschbar angeordnet sind. Dadurch können die feststehenden Sprühdüsen nicht nur zu Wartungszwecken aus dem Spülbehälter entnommen und wieder eingesetzt werden, sondern die Sprühdüsen können durch unterschiedlich gestaltete Sprühdüsen ersetzt werden, die eine andere Sprühcharakteristik aufweisen. Um die Sprühverteilung der Spülflüssigkeit innerhalb des Spülbehälters möglichst optimal zu gestalten, werden die Form und/oder die Anzahl der Öffnungen in den feststehenden Sprühdüsen für den Durchtritt der Spülflüssigkeit so ausgebildet, dass die gewünschte Spülung im Innenraum des Spülbehälters erzielt wird. Dabei kann eine möglichst gleichmäßige Sprühverteilung oder auch eine ungleichmäßige Sprühverteilung angestrebt werden, bei der bestimmte Bereiche im Spülbehälter stärker gespült werden als andere.It is particularly advantageous that the stationary spray nozzles are arranged in the floor, ceiling and / or wall region of the washing container in a manually detachable or exchangeable manner. As a result, the fixed spray nozzles can not only be removed from the rinsing container for maintenance purposes and reused, but the spray nozzles can be replaced by differently designed spray nozzles which have a different spray characteristic. In order to make the spray distribution of the rinsing liquid within the rinsing container as optimal as possible, the shape and / or the number of openings in the stationary spray nozzles for the passage of the rinsing liquid are formed so that the desired rinsing is achieved in the interior of the rinse. In this case, the most uniform possible spray distribution or even an uneven spray distribution can be sought, in which certain areas are rinsed in the washing more than others.

Auf diese Weise kann das von den feststehenden Sprühdüsen erzeugte Sprühmuster auf unterschiedliche Arten von Spülgut angepasst werden. Wenn beispielsweise bei größerem Spülgut, wie z.B. Pfannen, Töpfen oder Hohlgefäßen mit stärkeren Verunreinigungen eine besonders intensive Beaufschlagung mit Spülflüssigkeit erwünscht ist, können solche feststehenden Sprühdüsen in die Sprühvorrichtung eingesetzt werden, die starke oder verhältnismäßig eng gebündelte Spülflüssigkeitsstrahlen erzeugen. Dagegen kann zur Reinigung von empfindlichem Spülgut beispielsweise aus Porzellan oder Ton eine schwächere Beaufschlagung mit Spülflüssigkeit erwünscht sein, was durch den Einsatz von Sprühdüsen erreicht werden kann, die feine oder verhältnismäßig breit gefächerte Spülflüssigkeitsstrahlen erzeugen.In this way, the spray pattern generated by the fixed spray nozzles can be adapted to different types of items to be washed. For example, if larger items to be washed, such as pans, pots or hollow containers with stronger impurities particularly intense application of rinsing liquid is desired, such fixed spray nozzles can be used in the spray device that produce strong or relatively tightly bundled Spülflüssigkeitsstrahlen. In contrast, may be desired for cleaning sensitive items such as porcelain or clay weaker exposure to rinsing liquid, which can be achieved by the use of spray nozzles that produce fine or relatively wide rinse liquid jets.

Zweckmäßigerweise werden die feststehenden Sprühdüsen über eine Steckverbindung, eine Klemmverbindung, eine Schraubverbindung oder einen Bajonettverschluss mit dem Boden, der Decke oder der Wand des Spülbehälters verbunden. Solche Verbindungsarten ermöglichen eine schnelle und unkomplizierte Entnahme bzw. Austausch der feststehenden Sprühdüsen. Dabei kann die Verbindung der feststehenden Sprühdüsen mit dem Boden, der Decke oder der Wand des Spülbehälters besonders verschleißfrei und dauerhaft funktionsfähig gestaltet werden, wenn der Boden, die Decke und/oder die Wand des Spülbehälters im Bereich der feststehenden Sprühdüsen zumindest teilweise aus Kunststoff oder Metall gefertigt ist, wobei Edelstahl oder Aluminium aufgrund ihrer Resistenz gegen Rost aus hygienischen und optischen Gründen besonders geeignet sind.Conveniently, the fixed spray nozzles are connected via a plug connection, a clamp connection, a screw connection or a bayonet closure with the bottom, the ceiling or the wall of the washing compartment. Such types of connections enable a quick and uncomplicated removal or replacement of the fixed spray nozzles. In this case, the connection of the fixed spray nozzles with the bottom, the ceiling or the wall of the washing can be designed to be particularly wear-free and permanently functional if the bottom, the ceiling and / or the wall of the washing in the fixed spray nozzles at least partially made of plastic or metal is made of stainless steel or aluminum due to their resistance to rust for hygienic and optical reasons are particularly suitable.

Bei einer weiteren bevorzugten Ausführungsform der erfindungsgemäßen Geschirrspülmaschine liegt das zur Innenseite des Spülbehälters gerichtete Ende der feststehenden Sprühdüsen im wesentlichen in einer Ebene mit dem Boden, der Decke oder der Wand des Spülbehälters. Dadurch ist gewährleistet, dass die im Boden, der Decke und/oder der Wand des Spülbehälters angeordneten Sprühdüsen nicht in den Innenraum des Spülbehälters hineinragen und damit den für die Anordnung von Spülgut nutzbaren Raum im Spülbehälter nicht verringern.In a further preferred embodiment of the dishwasher according to the invention, the end of the stationary spray nozzles directed towards the inside of the washing container lies substantially in one plane with the bottom, the ceiling or the wall of the washing container. This ensures that the spray nozzles arranged in the bottom, the ceiling and / or the wall of the washing container do not protrude into the interior of the washing container and thus do not reduce the space in the washing container which can be used for the arrangement of dishes.

Die feststehenden Sprühdüsen können auch eine Doppelfunktion erfüllen, wenn sie einerseits beim Spülvorgang als Austrittsöffnungen für die Spülflüssigkeit verwendet werden und andererseits während eines Trocknungsvorgangs der Geschirrspülmaschine als Austrittsöffnungen für einen Luftstrom zur Trocknung des Spülguts dienen.The fixed spray nozzles can also fulfill a dual function if, on the one hand, they are used during the rinsing process as outlet openings for the rinsing liquid and, on the other hand, serve during a drying process of the dishwasher as outlet openings for an air flow for drying the items to be washed.

Die Versorgung einer Anzahl von feststehenden Sprühdüsen mit Spülflüssigkeit lässt sich besonders leicht bewerkstelligen, wenn die Sprüheinrichtung mindestens eine Spülflüssigkeit führende Spülflüssigkeitsleitung umfasst, die vorzugsweise im Boden-, Decken- undbder Wandbereich des Spülbehälters integriert ist und mit mindestens einer feststehenden Sprühdüse zum Zuführen von Spülflüssigkeit verbunden ist. Zweckmäßigerweise weist die Spülflüssigkeitsleitung dazu ein offenes Ende auf, über das Spülflüssigkeit von der Umwälzpumpe druckbeaufschlagt zugeführt werden kann, während die Spülflüssigkeitsleitung auf der zum Innenraum des Spülbehälters gerichteten Seite zumindest eine Öffnung aufweist, in die eine feststehende Sprühdüsen manuell einsetzbar ist. Dadurch ist eine ebenso einfache und damit kostengünstige als auch zuverlässige Versorgung der feststehenden Sprühdüsen mit Spülflüssigkeit bereitgestellt. The supply of a number of fixed spray nozzles with rinsing liquid can be accomplished particularly easily if the spraying device comprises at least one rinsing liquid-carrying rinsing liquid line, which is preferably integrated in the floor, ceiling and wall region of the rinsing container and with at least a fixed spray nozzle for supplying rinsing liquid is connected. Expediently, the rinsing liquid line has an open end, via which rinsing liquid can be supplied pressurized by the circulating pump, while the rinsing liquid line has at least one opening on the side directed toward the interior of the rinsing container into which a stationary spray nozzle can be manually inserted. As a result, an equally simple and therefore cost-effective as well as reliable supply of the fixed spray nozzles with flushing liquid is provided.
