Description

Geschirrkorb für eine Geschirrspülmaschine mit IntensivspülzoneDish rack for a dishwasher with intensive dishwashing zone
Die Erfindung betrifft einen Geschirrkorb für eine Geschirrspülmaschine mit einem Zuflussrohr für einen Sprüharm der unterhalb des Korbes rotierend gelagert ist, wobei im Bereich des Zuflussrohres ein Abzweig für eine im Bereich des Geschirrkorbes vorgesehene Intensivspülzone angeordnet ist.The invention relates to a dish rack for a dishwasher with an inlet pipe for a spray arm which is rotatably mounted below the basket, wherein in the region of the inflow pipe, a branch for a provided in the region of the dish rack Intensivspülzone is arranged.
Bei Geschirrspülmaschinen werden zu reinigende Spülgutteile wenigstens von einem Geschirrkorb aufgenommen und von unten und/oder oben mit Spülflüssigkeit beaufschlagt. Die Spülflüssigkeit wird den Spülgutteilen beispielsweise mittels eines unter dem Geschirrkorb angeordneten rotierbaren Sprüharmes zugeführt. Der Sprüharm wird von einer Umwälzpumpe gespeist, welche die Spülflüssigkeit in einem Zirkulationsbetrieb innerhalb der Geschirrspülmaschine hält.In dishwashers to be cleaned items to be washed are at least taken up by a dish rack and applied from below and / or above with rinsing liquid. The rinsing liquid is supplied to the items to be washed, for example by means of a rotatable spray arm arranged under the dish rack. The spray arm is fed by a circulation pump, which keeps the rinse liquid in a circulation mode within the dishwasher.
Bei diesen nach dem Stand der Technik rotierenden Düsenarmen ergeben sich so genannte Sprühschatten, so dass insbesondere in diesen Bereichen die aus dem Sprüharm austretenden Sprühstrahlen nicht immer effektiv das Spülgut erreichen. Ein derartiger Sprühschatten ergibt sich im Besonderen im Bereich einer doppelstöckigen Tassenauflage (s. beispielsweise DE 102004022024.7), wobei die obere Tassenauflage schwenkbar im Geschirrkorb untergebracht ist. Es ist dann wünschenswert, wenn besondere zusätzliche Sprühmitteleinrichtungen vorgesehen sind, die diese Bereiche, aber auch die unterschiedlichen Formen des Spülgutes berücksichtigen, um auf diese Weise eine effektive Reinigung zu erreichen bzw. den gezielten Einsatz des Spülmittels bereitzustellen.In the case of these nozzle arms rotating according to the prior art, so-called spray shadows result, so that in particular in these areas the spray jets emerging from the spray arm do not always effectively reach the items to be washed. Such a spray shadow results in particular in the area of a double-decker cup support (see, for example, DE 102004022024.7), wherein the upper cup support is pivotally accommodated in the crockery basket. It is desirable if special additional spray means are provided which take into account these areas, but also the different forms of the items to be washed, in order to achieve effective cleaning or to provide the targeted use of the detergent.
So ist beispielsweise aus der DE 19847 151 ein Geschirrkorb für eine Geschirrspülmaschine bekannt, auf dessen Boden Rohrleitungen angeordnet sind, die wiederum mit schwenkbar angeordneten Rohrstutzen versehen sind. Bei dieser Art der Ausführung sind insbesondere diese stutzenartigen Rohrendbereiche schwenkbar an den Rohrleitungen am Boden des Korbes derart gelagert, dass sie, wenn sie durch einfaches Verschwenken in die Gebrauchsstellung gebracht werden, auf diese Weise die Spülmittelzufuhr freigeben und somit einen gezielten Einsatz des Spülmittels ermöglichen.Thus, for example, from DE 19847 151 a dish rack for a dishwasher is known, on the bottom of which pipelines are arranged, which in turn are provided with pivotally arranged pipe stubs. In this type of embodiment, in particular, these nozzle-like Rohrendbereiche are pivotally mounted on the pipes at the bottom of the basket so that they, if they are brought by simple pivoting in the position of use, release in this way the detergent supply and thus allow a targeted use of the detergent.
Dieser nach dem Stand der Technik bekannte Geschirrkorb mit so genannten Sonderspülbereichen weist dahingehend den Nachteil auf, dass die Leitungsenden in den Korb ragen, was ein Verschieben von Tassen oder Gläsern im Bereich des Korbes behindert. Weiter wird durch diese Sonderspülzonen nur ein sehr begrenzter Bereich im Korb mit Spülflüssigkeit versorgt bzw. erfasst.This known in the prior art crockery basket with so-called special purging areas has the disadvantage that the cable ends protrude into the basket, which hinders a displacement of cups or glasses in the area of the basket. Further is supplied by this special rinsing only a very limited area in the basket with rinsing liquid or detected.
Gemäß einer anderen Variante des Standes der Technik, ist aus der FR 1.571.450 eine so genannte zusätzliche Sprüheinrichtung zu einem rotierenden Sprüharm bekannt, die insbesondere ihre Wirkung beim Oberkorb entfaltet. Hierbei ist ein zusätzlicher Arm an dem Zuflussrohr des Oberkorbes angeordnet, der insbesondere eine intensive Besprühung des Spülgutes von oben her gewährleistet. Auch diese zusätzliche Sprüheinrichtung birgt dahingehend noch Nachteile, da sie nicht als so genannte zusätzliche Intensivspülzone von unten her auf das Spülgut wirkt.According to another variant of the prior art, a so-called additional spraying device to a rotating spray arm is known from FR 1.571.450, which in particular unfolds its effect on the upper basket. In this case, an additional arm is arranged on the inflow pipe of the upper basket, which in particular ensures intensive spraying of the items to be washed from above. This additional spraying device also has disadvantages in that it does not act as a so-called additional intensive rinsing zone from below onto the items to be washed.
Hieraus ergibt sich die der Erfindung zugrunde liegende Aufgabe, einen Geschirrkorb für eine Geschirrspülmaschine mit einem Zuflussrohr für einen Spülraum derart weiter zu bilden, bei dem die Reinigungseffizienz durch zusätzliche Intensivspülzonen insbesondere von der Unterseite her wesentlich verbessert wird, wobei in der Anordnung der Intensivspülzone die Handhabbarkeit des Geschirrkorbes nicht beeinträchtigt wird.It follows from the object underlying the invention to further develop a crockery basket for a dishwasher with an inflow pipe for a washing compartment in which the cleaning efficiency is significantly improved by additional Intensivspülzonen in particular from the bottom, wherein in the arrangement of Intensivspülzone handleability of the dish rack is not affected.
Erfindungsgemäß wird dieses Problem durch einen Geschirrkorb mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindungen ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a crockery basket having the features of patent claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.
Nach einer ersten Ausführungsform wird vorgeschlagen die Intensivspülzone unterhalb der schwenkbaren Tassenauflage anzuordnen. Hierzu stehen die Leitungselemente über ein Ventil mit dem Abzweig in Verbindung, und wobei die Tassenauflage das Stellglied selbst bildet. Dies bringt insbesondere den Vorteil mit sich, dass die Intensivspülzone sich immer dann auch in der Aktivstellung befindet, wenn die Tassenauflage mit Tassen bestückt wird. Die Intensivspülzone der Tassenauflage wird somit immer von dem Bediener unbewusst mit aktiviert. Eine separate zusätzliche Stellanordnung erübrigt sich dadurch. Hierbei ist das Ventil im Bereich der Schwenkachse der Tassenauflage angeordnet, wobei das Ventil selbst aus einer Rohr in Rohr- Anordnung mit fluchtenden Öffnungen besteht. Es versteht sich von selbst, dass, wenn die Tassenauflage verschwenkt wird, die fluchtende Öffnungsstellung der Rohr in Rohr-Anordnung erfolgt, so dass die Intensivspülzone unterhalb der Tassenauflage aktiviert wird. Dabei sind in vorteilhafter Weise die Leitungselemente mit Halteklammern an den Streben der Tassenauflage derart befestigt, dass beim Verschwenken der Tassenauflage die Leitungselemente sich relativ zu der Unterseite der Tassenauflage bewegen können. Ein sich Verklemmen der Intensivspülzone unter der Tassenauflage wird dadurch verhindert, bzw. es wird ein leichtes einfaches Verschwenken der Tassenauflage dadurch gewährleistet. Den Abzweig im Bereich des Zuflussrohres für eine Intensivspülzone anzuordnen, die sich unterhalb des Korbes befindet, stellt keine Behinderung mehr für die Ablage des Geschirrs in dem Korb dar. Die Intensivspülzone besteht vorzugsweise aus stabförmigeή Leitungselementen, die über Ihren Umfang mit Austrittsdüsen versehen sind. Die Leitungselemente sind dabei an den Streben des Korbes befestigt. Somit lassen sich die Sprühschattenbereiche sicher erreichen. Die Leitungselemente stehen mit dem Abzweig über ein T-Stück in Verbindung.According to a first embodiment, it is proposed to arrange the intensive rinsing zone below the pivotable cup support. For this purpose, the line elements are connected via a valve with the branch, and wherein the cup support forms the actuator itself. This has the particular advantage that the Intensivspülzone is always in the active position when the cup support is equipped with cups. The intensive rinsing zone of the cup support is thus always unconsciously activated by the operator. A separate additional actuator assembly is unnecessary. Here, the valve is arranged in the region of the pivot axis of the cup support, wherein the valve itself consists of a tube in a tube arrangement with aligned openings. It goes without saying that, when the cup support is pivoted, the aligned opening position of the tube is in a tube arrangement, so that the intensive flushing zone is activated below the cup support. In this case, the line elements are fastened with retaining clips on the struts of the cup support in such an advantageous manner that when pivoting the cup support the line elements can move relative to the bottom of the cup support. A jamming of Intensivspülzone under the cup support is thereby prevented, or it is a slight easy pivoting of the cup support guaranteed. Disposing the branch in the area of the inlet pipe for an intensive rinse zone located below the basket no longer interferes with the placement of the dishes in the basket. The intensive rinse zone preferably consists of rod-shaped line elements provided with outlet nozzles around their circumference. The line elements are attached to the struts of the basket. Thus, the spray shadow areas can be reached safely. The pipe elements are connected to the branch via a T-piece.
Nach einer zweiten vorteilhaften Ausführungsform ist dabei wenigstens ein Leitungselement drehbar gelagert und wirkt mit einem separat angeordneten Stellglied derart zusammen, dass die Intensivspülzone nach Bedarf von Hand zu- oder abgeschaltet werden kann. Um die Zu- und Abschaltbarkeit zu erlangen, weist das drehbare Leitungselement an seinem einen Ende einen Aufnahmebereich für das Stellglied auf, wobei das andere Ende mit einer Aussparung zur Herstellung der Durchflussöffnung beider Leitungselemente versehen ist. Es versteht sich nun von selbst, dass eines der beiden Leitungselemente mit seinem Endbereich wie ein Ventil wirkt, um die von dem Abzweig zulaufende Spülflüssigkeit für den Intensivspülbereich zu- oder abzuschalten. Hierbei ist es besonders zweckmäßig, dass der Abzweig vorzugsweise am Endbereich des Zuflussrohres angeordnet ist. Da das Zuflussrohr bis in das Zentrum des Korbes reicht, ergeben sich für die Leitungselemente keine Strömungsverluste, da sie jeweils über gleiche Längen mit Spülflüssigkeit versorgt werden.According to a second advantageous embodiment, at least one line element is rotatably mounted and interacts with a separately arranged actuator in such a way that the Intensivspülzone can be switched on or off as needed by hand. In order to obtain the connectivity and disconnectability, the rotatable conduit member has at its one end a receiving area for the actuator, wherein the other end is provided with a recess for producing the flow opening of both conduit elements. It now goes without saying that one of the two line elements acts with its end region like a valve in order to switch on or off the rinsing liquid for the intensive rinsing area which flows from the branch. In this case, it is particularly expedient that the branch is preferably arranged at the end region of the inflow pipe. Since the inflow pipe extends into the center of the basket, there are no flow losses for the line elements, since they are each supplied with rinsing liquid over equal lengths.
Ein Ausführungsbeispiel der Erfindung wird anhand der nachstehenden Figuren 1 bis 8 näher erläutert, dabei zeigen:An embodiment of the invention will be explained in more detail with reference to the following figures 1 to 8, in which:

A branch 3 for an intensive rinsing zone 4 provided in the region of the dish rack 1 is located in the region of the inflow pipe 2. The isolated representation of the intensive rinsing zone is preferably shown in FIGS. 2, 3 and 3.1. It can be seen clearly from FIG. 2 that the intensive rinsing zone 4 preferably consists of rod-shaped line elements 5 and 6, which are provided with outlet nozzles 7. The
Leitungselemente 5 und 6 sind hierbei an den Streben 8 des Korbes 1 befestigt und mit dem Abzweig 3 über ein T-Stück 10 verbunden.

Wie aus der11.1 fed with rinsing liquid, wherein the valve 11.1 as such communicates with the branch 3. Here, the cup support 1.1 forms the actuator 11 itself, so that the valve 11.1 opens or closes by pivoting the cup support 1.1. Like from the
Zusammenschau der Figur 3 und der Figur 3.1 in der geschnittenen Darstellung deutlich wird, ist das Ventil 11.1 im Bereich der Schwenkachse 1.2 der Tassenauf läge 1.1 angeordnet, wobei das Ventil 11.1 selbst aus einer Rohr in Rohr-Anordnung mit fluchtenden Öffnungen 16.1 undView of Figure 3 and Figure 3.1 in the sectional view is clear, the valve 11.1 is in the region of the pivot axis 1.2 of the Tassenauf 1.1 arranged, wherein the valve 11.1 itself from a pipe in a pipe arrangement with aligned openings 16.1 and
16.2 in der Durchlassstellung besteht, wie dies in der Figur 3 dargestellt ist. Aus der Figur 3.1 in der Zusammenstellung wird deutlich, wie das Ventil 11.1 sperrt, wenn die Tassenauflage 1.1 nach oben verschwenkt ist. In dieser Stellung der Tassenauflage 1.1 ist die Öffnung 16.2 gegenüber der Öffnung 16.1 so verschwenkt, dass der Durchlass für die Spülflüssigkeit zur Intensivspülzone 4 unterbrochen ist.16.2 is in the passage position, as shown in FIG. From the figure 3.1 in the compilation is clear how the valve 11.1 locks when the cup support 1.1 is pivoted upwards. In this position of the cup support 1.1, the opening 16.2 is pivoted relative to the opening 16.1 so that the passage for the rinsing liquid to Intensivspülzone 4 is interrupted.
Nicht näher in den Darstellungen zu erkennen ist, dass die Leitungselemente 5 und 6 mit Halteklammern an den Streben 8 der Tassenauflage 1.1 befestigt sind. Die Halteklammern ermöglichen, dass beim Verschwenkvorgang der Tassenauf läge 1.1 die Leitungselemente 5 und 6 gegenüber den Streben 8 der Tassenauf läge 1.1 eine leichte Relativbewegung zulassen. Hierdurch wird ein behinderungsfreier Schwenkvorgang für die Tassenauflage 1.1 gewährleistet. Aus der Figur 2 wird noch deutlich, dass die Verbindungsleitung zwischen dem Abzweig 3 und dem Ventil 11.1 aus zwei L-förmigen Rohren gebildet ist, die ebenfalls im Verbindungsbereich eine Schwenkstelle 17 bilden.It can not be seen in more detail in the illustrations that the line elements 5 and 6 are fastened with retaining clips to the struts 8 of the cup support 1.1. The retaining clips allow that during the pivoting operation of the Tassenauf 1.1 the line elements 5 and 6 relative to the struts 8 of the Tassenauf 1.1 allow a slight relative movement. As a result, a disability-free pivoting process for the cup support 1.1 is guaranteed. From the figure 2 it is still clear that the connecting line between the branch 3 and the valve 11.1 is formed of two L-shaped tubes, which also form a pivot point 17 in the connecting region.
Die Figur 4 zeigt in der Draufsicht einen Geschirrkorb 1 und hier insbesondere den oberen Geschirrkorb einer nicht näher dargestellten Geschirrspülmaschine. Mit dem Geschirrkorb 1 steht ein Zuflussrohr 2 in Verbindung, welches einen ebenfalls nicht näher dargestellten Sprüharm, der unterhalb des Korbes 1 rotierend gelagert ist, mit Spülflüssigkeit speist. Endseitig am Zuflussrohr 2 ist ein Abzweig 3 für eine im Bereich des Spülkorbes 1 vorgesehene Intensivspülzone 4 gemäß einer zweiten Ausführungsform angeordnet. Diese ist deutlicher auch in der Figur 5 zu erkennen, wo insbesondere in der Perspektive die Wirkverbindung der Intensivspülzone 4 mit dem Zuflussrohr 2 deutlich wird. Es versteht sich nun von selbst, dass, wenn das Zuflussrohr 2 über die Umwälzpumpe mit Spülflüssigkeit über den Abzweig 3 versorgt wird, auch die Intensivspülzone 4 gespeist wird.FIG. 4 shows a top view of a dish rack 1 and, in particular, the upper dish rack of a dishwashing machine (not shown). With the dish rack 1 is an inlet pipe 2 in connection, which feeds a spray arm, also not shown, which is rotatably mounted below the basket 1, with rinsing liquid. At the end of the inflow pipe 2, a branch 3 is arranged for an intensive rinsing zone 4 provided in the region of the rinsing basket 1 in accordance with a second embodiment. This can also be seen more clearly in FIG. 5, where the operative connection of the intensive rinsing zone 4 with the inflow pipe 2 becomes clear, especially in perspective. It goes without saying that when the inflow pipe 2 is supplied via the circulating pump with rinsing liquid via the branch 3, and the Intensivspülzone 4 is fed.
Wie insbesondere aus der Figur 4 zu erkennen ist, befindet sich in vorteilhafter Weise die Intensivspülzone 4 unterhalb des Korbes 1. Sie stellt somit keine Behinderung im Bereich der oberen Korbaufnahme dar. Die Intensivspülzone 4 besteht dabei vorzugsweise ebenfalls aus stabförmigen Leitungselementen 5 und 6, die über ihren Umfang, besser zu erkennen in den Figuren 7 und 8, mit Austrittsdüsen 7 versehen sind. Um einen festen Halt der Intensivspülzone 4 am Korbgitter zu erreichen, sind die Leitungselemente 5, 6 an einer Strebe 8 des Korbes 1 befestigt. Hierzu können beispielsweise Klammerelemente 9 an den Leitungselementen 5 und 6 vorgesehen sein, die die Strebe 8 umgreifen.As can be seen in particular from FIG. 4, the intensive rinsing zone 4 is located below the basket 1 in an advantageous manner. It thus does not constitute a hindrance in the area of the upper basket receptacle. The intensive rinsing zone 4 preferably also consists of rod-shaped line elements 5 and 6 which are provided with outlet nozzles 7 over their circumference, better seen in Figures 7 and 8. In order to achieve a firm grip of the intensive rinsing zone 4 on the basket grid, the line elements 5, 6 are fastened to a strut 8 of the basket 1. For this purpose, for example, clip elements 9 may be provided on the line elements 5 and 6, which surround the strut 8.
Wie aus der perspektivischen Darstellung der Figur 5 zu erkennen ist, stehen die Leitungselemente 5 und 6 mit dem Abzweig 3 über ein T-Stück 10 in Verbindung. Dabei ist das vordere Leitungselement 5 drehbar gelagert, welches in Einzelansicht auch in den Figuren 7 und 8 nochmals dargestellt ist. Das drehbar gelagerte Leitungselement 5 wirkt dabei mit dem Stellglied 11, zu erkennen in der Figur 6, derart zusammen, dass die Intensivspülzone 4 je nach Bedarf zu- oder abgeschaltet werden kann. Um dies zu erreichen, weist das drehbar gelagerte Leitungselement 5, zu erkennen in der Figur 7 und 8, an seinem einen Ende 12 einen Aufnahmebereich für das Stellglied 11 auf, wobei das andere Ende 13 mit einer Aussparung 14 versehen ist. Die Herstellung der Durchflussöffnung oder Schließung beider Leitungselemente 5 und 6 erfolgt dadurch, dass die Aussparung 14 in dem T-Stück 10 verschwenkt wird.As can be seen from the perspective view of Figure 5, the line elements 5 and 6 are connected to the branch 3 via a T-piece 10 in connection. In this case, the front conduit member 5 is rotatably mounted, which is shown in single view in the figures 7 and 8 again. The rotatably mounted line element 5 acts with the actuator 11, visible in the figure 6, together such that the Intensivspülzone 4 can be switched on or off as needed. To achieve this, the rotatably mounted conduit member 5, visible in Figures 7 and 8, at its one end 12 a receiving area for the actuator 11, wherein the other end 13 is provided with a recess 14. The production of the flow opening or closure of both line elements 5 and 6 takes place in that the recess 14 is pivoted in the T-piece 10.
Es versteht sich nun von selbst, dass, wenn das Leitungselement 5 um 180° verschwenkt wird, die Aussparung 14 entweder zum Abzweig 3 weist, so dass die Intensivspülzone 4 geöffnet ist, oder dass die Aussparung 14 mit Ihrem Rückenbereich den Abzweig 3 versperrt, so dass keine Spülflüssigkeit in die Intensivspülzone 4 gelangen kann. Eine entsprechende Einstellung kann mit dem Stellglied 11 vorgenommen werden, welches in der dort dargestellten Stellung insbesondere die Offen-Stellung der Intensivspülzone 4 zeigt. Wird das Stellglied 11 auf die Null-Position, also um 180° gedreht, so wird die Intensivspülzone 4 abgeschaltet.It goes without saying that, when the conduit member 5 is pivoted through 180 °, the recess 14 either to the branch 3 has, so that the Intensivspülzone 4 is open, or that the recess 14 blocks the branch 3 with your back area, so that no Rinse liquid can enter the Intensivspülzone 4. A corresponding setting can be made with the actuator 11, which in the position shown there, in particular, the open position of the Intensivspülzone 4 shows. If the actuator 11 to the zero position, that is rotated by 180 °, the Intensivspülzone 4 is turned off.
Nach einer besonders vorteilhaften Weiterbildung der Erfindung, die nicht explizit dargestellt ist, kann die Intensivspülzone 4 auch derart ausgebildet sein, dass sie aus einem durchgehenden stabförmigen Leitungselement mit Austrittsdüsen besteht, welches über den Abzweig 3 mit dem Zuflussrohr 2 in Verbindung steht. Dabei kann im Leitungsabschnitt 15 des Abzweigs 3 ein nicht näher dargestelltes Stellventil zum Zu- oder Abschalten vorgesehen sein. Das Stellventil selbst wird mittels einer ebenfalls nicht näher dargestellten Stange betätigt, die mit einem Drehknauf versehen ist, wie beispielsweise das Stellglied 11. According to a particularly advantageous embodiment of the invention, which is not explicitly shown, the Intensivspülzone 4 may also be formed such that it consists of a continuous rod-shaped line element with outlet nozzles, which is connected via the branch 3 with the inlet pipe 2 in connection. In this case, in the line section 15 of the branch 3, a not-shown control valve may be provided for connection or disconnection. The control valve itself is actuated by means of a rod, also not shown, which is provided with a rotary knob, such as the actuator eleventh
