The bridges are inclined so as to form a diamond-shaped cross-section.

Description

Die Erfindung betrifft eine Geschirrspülmaschine mit mindestens einem Geschirrkorb, die mit zumindest ein Teilprogramm Trocknen sowie ein Teilprogramm Spülen umfassenden Reinigungsprogrammen betätigbar ist, sowie mit einem mit Besteckteilen und/oder Kleingeschirr bestückbaren Einsatz, insbesondere Besteckkorb, der mehrere Durchbrüche für den Durchtritt von Spülflüssigkeit aufweist, die von in einer Ebene an Kreuzungspunkten sich schneidenden Stegen begrenzt werden.The invention relates to a dishwasher with at least one crockery basket, which can be actuated with cleaning programs comprising at least one drying sub-program and one rinsing sub-program, and with an insert that can be fitted with cutlery items and/or small crockery, in particular a cutlery basket, which has several openings for the passage of washing liquid, which are delimited by webs that intersect in one plane at crossing points.

Aus der deutschen Offenlegungsschrift DE 44 14 347 ist ein Verfahren zum Betrieb einer Geschirrspülmaschine bekannt, die mit zumindest einem Teilprogramm Trocknen sowie einem Teilprogramm Spülen umfassenden Reinigungsprogrammen betätigbar ist.From the German Offenlegungsschrift DE 44 14 347 a method for operating a dishwasher is known which can be actuated with cleaning programs comprising at least one drying sub-program and one rinsing sub-program.

Aus dem deutschen Patent DE 36 41 020 ist eine Einrichtung in einer Geschirrspülmaschine zum Reinigen und Trocknen von Besteckteilen und Kleingeschirr bekannt, die eine Verbesserung der Trocknungsleistung gegenüber vorherigen Einrichtungen ermöglicht. Dabei weist zumindest ein Geschirrkorb einen darin einsetzbaren Besteckkorb mit jeweils in dem Besteckkorbboden und den Besteckkorbseitenwänden vorhandenen Durchbrüchen für den Durchtritt von Spülflüssigkeit auf. Zusätzlich ist ein Tablett mit weiteren Durchbrüchen für einhängbare Besteckteile und/oder Halterungen bzw. Aufnahmen für Kleingeschirr in den Korbboden des Geschirrkorbs einsetzbar oder auf den Besteckkorbdeckelförmig aufsetzbar. Die somit in den Seitenwänden, dem Boden und der Abdeckung von Besteckkorb und/oder Tablett angeordneten Durchbrüche werden jeweils von sich in einer Ebene rechtwinklig kreuzenden geraden Stegen begrenzt.From the German patent DE 36 41 020 a device in a dishwasher for cleaning and drying pieces of cutlery and small crockery is known, which allows the drying performance to be improved compared to previous devices. In this case, at least one crockery basket has a cutlery basket which can be inserted therein and which has openings in the bottom of the cutlery basket and in the side walls of the cutlery basket for the passage of washing liquid. In addition, a tray with further openings for cutlery that can be hung up and/or holders or holders for small dishes can be inserted into the base of the crockery basket or placed on the cutlery basket in the form of a lid. The openings thus arranged in the side walls, the base and the cover of the cutlery basket and/or tray are each delimited by straight webs crossing at right angles in a plane.

Aus dem deutschen Gebrauchsmuster DE 76 05 749 ist eine Einrichtung bekannt, bei der die Stege, die die Durchbrüche des Besteckkorbbodens begrenzen, geneigt verlaufende Stegabschnitte aufweisen. Diese Stegabschnitte gehen von der Ebene des Besteckkorbbodens aus und vereinigen sich außerhalb dieser Ebene. Der Vorteil dieses - jedoch schwierig herzustellenden Besteckkorbes besteht im Vergleich zu den waagrecht verlaufenden Stegen in einem verbesserten Tropfenablauf nur vom Boden des Besteckkorbes.From the German utility model DE 76 05 749 a device is known in which the webs that delimit the openings in the bottom of the cutlery basket have inclined web sections. These web sections start from the level of the cutlery basket base and unite outside of this level. The advantage of this cutlery basket, however, which is difficult to produce, consists in an improved drainage of drops only from the bottom of the cutlery basket compared to the horizontally running webs.

Aus der deutschen Offenlegungsschrift DE 198 20 979 ist eine Einrichtung für Geschirrspülmaschinen bekannt, bei der die zu einer Besteckablage gehörigen und miteinander gekoppelte Stege höherliegende und tieferliegende Stellen nach Art einer Pyramide aufweisen, um die Trocknungsleistung der Besteckablage zu verbessern. In den deutschen Offenlegungsschriften 195 40 610 und 195 40 611 sind - auch als Etagéren bezeichnete - Ablagen für Geschirrkörbe in einer Geschirrspülmaschine beschrieben, die jeweils als Einsatz zum Reinigen und Trocknen von Besteckteilen und/oder Kleingeschirr fest oder beweglich mit dem Geschirrkorb verbunden und/oder lose angeordnet sein können.From the German Offenlegungsschrift DE 198 20 979 a device for dishwashers is known in which the webs that belong to a cutlery tray and are coupled to one another have higher and lower points in the manner of a pyramid in order to improve the drying performance of the cutlery tray. In the German disclosure documents 195 40 610 and 195 40 611 are - also known as Etagéren - shelves for crockery baskets in a dishwasher described, which can be fixed or movably connected to the crockery basket and / or loosely arranged as an insert for cleaning and drying cutlery and / or small dishes.

Die bekannten Einrichtungen haben alle den Nachteil, dass oftmals Spülflüssigkeit z.B. auf einer horizontalen Fläche - verbleibt, die nicht selbständig abläuft, sondern abtrocknen muss. Anlehnende Besteckteile sind daher selbst nach der Trocknungsphase eines Reinigungsprogramms meist am Schaft noch nass. Darüber hinaus benetzen sich ein Besteckkorb und/oder andere Einrichtungen in nachteiliger Weise verstärkt in den Ecken der einzelnen rechteckig ausgestalteten Durchbrüche oder Öffnungen, wo die Besteckteile üblicherweise anliegen, d.h. es existiert eine Vielzahl von "Anlegestellen" für die Spülflüssigkeit, die die Trocknung erschweren bzw. die Trocknungsphase verlängern und zur Bildung von Trocknungsflecken auf den Besteckteilen führen.The known devices all have the disadvantage that rinsing liquid often remains, e.g. Leaning pieces of cutlery are therefore usually still wet on the shaft even after the drying phase of a cleaning program. In addition, a cutlery basket and/or other equipment disadvantageously gets wet to a greater extent in the corners of the individual rectangular openings or openings where the cutlery usually rests, i.e. there are a large number of "landing points" for the washing liquid, which make drying difficult or slow down .extend the drying phase and lead to the formation of drying spots on the cutlery.

Der Besteckkorb der WO 89/000022 weist zur Ablage von zu spülenden und zu trocknenden Besteckteilen Besteckhalter und Besteckauflagen auf. Die Besteckauflagen sind mit unterschiedlich profilierten Auflageflächen und/oder verschiedenen Auflagehöhenversehen. Die Besteckauflagen sind unter Bildung von Besteckauflagegruppen in wechselnder Folge im Besteckkorb angeordnet. Die Besteckauflagen der einen Besteckauflagegruppe sind mit sägezahnförmig gestalteten Auflageflächen und die Besteckauflagen der weiteren Besteckauflagegruppe mit schneidenförmig gestalteten, ebenen Auflageflächen für die Besteckteile ausgebildet, wobei die schneidenförmig gestalteten, ebenen Besteckauflagen die größere Auflagehöhe besitzen. Der Bestecktrockner der DE 15 03 780 A1 umfasst ein Gehäuseteil und ein Gehäuseunterteil, die mit waagrechter Trennungsebene köcherartig zusammensteckbar sind. Das Gehäuseoberteil weist eine oben offene Fachaufteilung und einen Bodenabschluss mit in diesem angeordneten Ablauföffnungen auf. Zur Bildung verschieden tiefer Aufnahmefächer erstreckt sich der Bodenabschluss für die Fachaufteilung in verschiedenen parallelen Ebenen.The cutlery basket WO 89/000022 has cutlery holders and cutlery supports for storing items of cutlery to be washed and dried. The cutlery supports are provided with differently profiled support surfaces and/or different support heights. The cutlery supports are arranged in alternating sequence in the cutlery basket to form cutlery support groups. The cutlery supports of a cutlery support group are designed with sawtooth-shaped support surfaces and the cutlery supports of the further cutlery support group are designed with blade-shaped, flat support surfaces for the cutlery, the blade-shaped, flat cutlery supports having the greater support height. The cutlery dryer DE 15 03 780 A1 comprises a housing part and a lower housing part, which can be plugged together like a quiver with a horizontal parting plane. The upper part of the housing has a compartment division that is open at the top and a bottom closure with drainage openings arranged in it. For education compartments of different depths, the bottom edge for the compartment division extends in different parallel levels.

Der Erfindung liegt die Aufgabe zu Grunde, eine Geschirrspülmaschine mit einem mit Besteckteilen und/oder Kleingeschirr bestückbaren Einsatz, insbesondere Besteckkorb, zu schaffen, durch den ein gegenüber bekannten Lösungen zusätzlich verbessertes Trocknungsergebnis für die Besteckteile und/oder das Kleingeschirr erzielbar ist.The invention is based on the object of creating a dishwasher with an insert, in particular a cutlery basket, which can be fitted with cutlery and/or small crockery, through which an additionally improved drying result for the cutlery and/or small crockery can be achieved compared to known solutions.

Diese Aufgabe wird bei einer Geschirrspülmaschine mit den Merkmalen des Anspruchs 1 dadurch gelöst, dass der mit Besteckteilen und/oder Kleingeschirr bestückbare Einsatz, insbesondere Besteckkorb, als Mittel, die in Problemzonen des Einsatzes, insbesondere Besteckkorbs, das Ablaufen von Tropfen einer Spülflüssigkeit bewirken, vorsieht, dass die sich schneidenden Stege derart geneigt ausgebildet sind, dass sie jeweils einen rautenförmigen Querschnitt aufweisen und jeweils im Bereich ihrer Kreuzungspunkte eine Art von Doppelpyramide bilden.This object is achieved in a dishwasher with the features of claim 1 in that the insert, in particular the cutlery basket, which can be fitted with pieces of cutlery and/or small crockery, provides means which cause drops of washing liquid to run off in problem zones of the insert, in particular the cutlery basket that the intersecting webs are inclined in such a way that they each have a rhombic cross section and each form a kind of double pyramid in the region of their crossing points.

Sonstige Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Other developments of the invention are specified in the dependent claims.

Ausgehend von einer Einrichtung der eingangs genannten Art sind die erfindungsgemäßen Mittel an einem mit Besteckteilen und/oder Kleingeschirr bestückbaren Einsatz zum Ablaufen von Tropfen einer Spülflüssigkeit ausgebildet, die das Ablaufen von Tropfen einer Spülflüssigkeit in Problemzonen des Einsatzes bewirken. Diese Mittel führen dazu, dass Flüssigkeitsstropen selbstständig und von allein ablaufen und somit die Bildung unerwünschter Trocknungsflecken auf den Besteckteilen und/oder dem Kleingeschirr verhindert wird. Eine noch bessere Trocknungsleistung und eine Verkürzung der Trocknungsphase als bei bekannten Einrichtungen ist die Folge.Based on a device of the type mentioned above, the means according to the invention are on a piece of cutlery and/or small crockery fittable insert designed to drain drops of rinsing liquid, which cause the draining of drops of rinsing liquid in problem areas of the insert. These agents cause drops of liquid to run off automatically and by themselves, thus preventing the formation of undesirable drying spots on the cutlery and/or small dishes. The result is an even better drying performance and a shorter drying phase than with known devices.

Erfindungsgemäß weist der Einsatz, insbesondere Besteckkorb, als Mittel, die in Problemzonen das Ablaufen von Tropfen einer Spülflüssigkeit bewirken, mehrere Durchbrüche für den Durchtritt der Spülflüssigkeit auf, die von in einer Ebene an Kreuzungspunkten sich schneidenden Stegen begrenzt werden, die derart geneigt ausgebildet sind, dass sie jeweils einen rautenförmigen Querschnitt aufweisen. Durch das rautenförmige Profil der geneigt ausgebildeten Stege entsteht an den Kreuzungspunkten eine Art von Doppelpyramide. Durch das rautenförmige Profil und das an den Kreuzungspunkten entstehende doppelpyramidenförmige Profil kann die Spülflüssigkeit - besonders an den kritischen Stellen - über die auf allen Seiten der Raute bzw. Doppelpyramide existierenden schrägen Flächen selbstständig nach unten ablaufen. Damit wird das Verbleiben der Spülflüssigkeit auf horizontalen Flächen und an den zahlreichen Anlegestellen besonders an den Kreuzungspunkten vermieden. Insgesamt ergibt sich einen derart gestalteten Einsatz ein gegenüber bekannten Lösungen wesentlich verbessertes Trocknungsergebnis für die in den Einsatz gegebenen Teile - vor allem Besteckteile und/oder Kleingeschirr. Auch die nachteilige verstärkte Benetzung bei bekannten Einsätzen an den zahlreichen Anlegestellen und besonders in den Ecken der einzelnen Durchbrüche oder Öffnungen, wird durch im Querschnitt rautenförmig ausgebildeten geneigten Stege entschärft, was die Trocknung verbessert und die Trocknungsphase verkürzt und das Entstehen von Trocknungsflecken auf den Besteckteilen verhindert.According to the invention, the insert, in particular the cutlery basket, has a plurality of openings for the passage of the washing liquid as a means which causes drops of washing liquid to run off in problem zones, which are delimited by webs which intersect in a plane at crossing points and which are designed inclined in such a way that that they each have a diamond-shaped cross section. The diamond-shaped profile of the sloping webs creates a kind of double pyramid at the crossing points. Due to the diamond-shaped profile and the double-pyramid-shaped profile created at the crossing points, the rinsing liquid - especially at the critical points - can run off independently downwards via the sloping surfaces on all sides of the diamond or double-pyramid. This avoids the rinsing liquid remaining on horizontal surfaces and on the numerous mooring points, especially at the crossing points. Overall, an insert designed in this way results in a significantly improved drying result for the parts placed in the insert—especially cutlery and/or small crockery—compared to known solutions. The disadvantageous increased wetting with known inserts at the numerous landing points and especially in the corners of the individual openings or openings is mitigated by inclined webs with a diamond-shaped cross section, which improves drying and shortens the drying phase and prevents drying spots on the cutlery items .

Gemäß einer weiteren Ausgestaltung der Erfindung sind die Durchbrüche des Einsatzes jeweils im Bereich der Kreuzungspunkte durch Radien abgerundet ausgebildet. Dadurch kann die Spülflüssigkeit durch die in den "Ecken" abgerundeten Durchbrüche noch besser abfließen, was das Trocknen besonders der an den Durchbrüchen normalerweise in den "Ecken" - d.h. Problemzonen - anliegenden Besteckteile und/oder Kleingeschirr in vorteilhafter Weise während der Trocknungsphase beschleunigt.According to a further embodiment of the invention, the openings of the insert are rounded off by radii in the area of the crossing points. As a result, the rinsing liquid can flow off even better through the openings that are rounded off in the "corners", which facilitates the drying of the openings normally in the "corners" - ie problem zones - in particular Cutlery and / or small dishes accelerated in an advantageous manner during the drying phase.

Gemäß einer alternativen, aber ebenso günstigen Weiterbildung der Erfindung weist der mit jeweils durch Trennwände voneinander abgegrenzten Einsatzfächern aufgebaute Einsatz zumindest zwei Einsatzfächer mit in verschiedenen Höhen angeordneten Fachböden zum Einstellen von unterschiedlichen Besteckteilen und/oder Kleingeschirr auf. Insgesamt ergibt sich einen derart gestalteten Einsatz ein gegenüber bekannten Lösungen wesentlich verbessertes Trocknungsergebnis für die in den Einsatz gegebenen Besteckteile und/oder Kleingeschirr. Die Besteckteile und/oder das Kleingeschirr können abhängig von ihrer jeweiligen Länge/Größe/Form in das Einsatz fach mit zugehörigem Fachboden in der geeigneten Höhe eingestellt werden, so dass sie am Fachboden aufstehen und nicht mehr eingehängt werden müssen. Der selbstständige Ablauf von Spülflüssigkeitstropfen, die ansonsten zu den unerwünschten Trockenflecken führten, wird durch diese einfache, aber effektive Maßnahme unterstützt. Das Einhängen besonders der kleinen Teile in eine Abdeckung, was die erwähnten Ablaufprobleme für die Tropfen verursacht, entfällt durch die Einsatzfächer mit unterschiedlich hohen Fachböden.According to an alternative but equally favorable development of the invention, the insert constructed with insert compartments each separated from one another by partitions has at least two insert compartments with shelves arranged at different heights for placing different cutlery items and/or small crockery. Overall, an insert designed in this way results in a significantly improved drying result for the pieces of cutlery and/or small crockery placed in the insert compared to known solutions. Depending on their respective length/size/shape, the cutlery and/or small crockery can be placed in the insert compartment with the associated shelf at the appropriate height so that they stand up on the shelf and no longer have to be hung up. This simple but effective measure supports the automatic drainage of drops of washing liquid, which would otherwise lead to unwanted dry stains. The hanging of the small parts in a cover, which causes the drainage problems mentioned for the drops, is no longer necessary thanks to the insert compartments with shelves of different heights.

Gemäß einer weiteren Ausgestaltung der Erfindung sind die Höhen der Fachböden an die Länge und/ oder Größe der Besteckteile und/oder des Kleingeschirrs anpassbar. Dadurch entstehen je nach Bedarf partiell in der Nutzhöhe angepasste Sektionen als variable Einsatzfächer, die zu einem variabel gestaltbaren Einsatz für unterschiedlichste Besteckteile und/oder Kleingeschirr kombiniert werden können.According to a further embodiment of the invention, the heights of the shelves can be adapted to the length and/or size of the cutlery items and/or the small crockery. Depending on requirements, this creates sections that are partially adjusted in terms of useful height as variable insert compartments, which can be combined to form an insert that can be variably designed for a wide variety of cutlery items and/or small crockery.

Gemäß einer vorteilhaften Variante bilden die Einsatzfächer einen Besteckkorb, der durch die Fachböden einen unterschiedliche Nutzhöhe aufweisenden Besteckkorbboden aufweist.According to an advantageous variant, the insert compartments form a cutlery basket which, due to the compartment floors, has a cutlery basket base with a different usable height.

Figur 1 und Figur 2 zeigen nur einen - für die Darstellung des Prinzips der Erfindung aber ausreichen - Ausschnitt der Einrichtung zur Verbesserung der Trocknungsleistung. Diese Einrichtung umfasst einen Einsatz, der beispielsweise als Besteckkorb zur Bestückung mit Besteckteilen und/oder Kleingeschirr in einer Geschirrspülmaschine in einem Geschirrkorb lose angeordnet oder daran fest oder beweglich angebracht sein kann. Der prinzipielle Aufbau eines Besteckkorbes mit Seitenwänden, Boden und/oder Abdeckung entspricht dem im Patent DE 36 41 020 beschriebenen Einsatz. Auch die Verwendung des Einsatzes mit Mitteln gemäß dem Gegenstand der Erfindung als eine mit Besteckteilen und/oder Kleingeschirr bestückbare Ablage - eine Etagére - ist möglich. Figure 1 and Figure 2 show only one - but sufficient for the presentation of the principle of the invention - section of the device for improving the drying performance. This device includes an insert that can be loosely arranged in a dishwasher basket or attached to it in a fixed or movable manner, for example as a cutlery basket for loading items of cutlery and/or small dishes in a dishwasher. The basic structure of a cutlery basket with side walls, base and/or cover corresponds to that in the patent DE 36 41 020 described use. It is also possible to use the insert with means according to the subject matter of the invention as a shelf—an etagere—that can be fitted with cutlery pieces and/or small crockery.

Der Ausschnitt des Einsatzes nach dem Stand der Technik in Figur 1 umfasst zwei längs verlaufende Stege 1 und 2 sowie zwei quer verlaufende Stege 3 und 4, die sowohl die Seitenwände des Einsatzes als auch für den Besteckkorbboden und/oder die Besteckkorbabdeckung eines Besteckkorbes bilden können. Dabei schneiden sich die Stege 1 und 2 mit den Stegen 3 und 4 an vier Kreuzungspunkten 5, 6, 7 und 8 und begrenzen dadurch einen Durchbruch 9, der eine Öffnung zum Durchtritt von Spülflüssigkeit 10 bildet.The prior art insert cutout in figure 1 comprises two longitudinal webs 1 and 2 and two transverse webs 3 and 4, which can form both the side walls of the insert and for the cutlery basket bottom and/or the cutlery basket cover of a cutlery basket. The webs 1 and 2 intersect with the webs 3 and 4 at four crossing points 5, 6, 7 and 8 and thereby delimit an opening 9 which forms an opening for the flushing liquid 10 to pass through.

Die sich schneidenden Stege 1 bis 4 sind jeweils an den Kreuzungspunkten 5 bis 8 - von denen die Figur 1 einen Kreuzungspunkt 7 beispielhaft in der Ansicht des Querschnitts bzw. des Profils zeigt - vorzugsweise nach unten geneigt nach Art eines Kegels 11 ausgebildet, um das Trocknungsergebnis für die Besteckteile und/oder das Kleingeschirr gegenüber den bekannten Einsätzen mit gerade verlaufenden Stegen zu verbessern. Die Figur 1 zeigt dennoch bestehende Problemzonen, an denen Spülflüssigkeit 10 trotz geneigter Stege verbleibt und nicht von allein abfließen kann. Dies sind vor allem die horizontalen Flächen des Einsatzes sowie die Ecken der einzelnen Durchbrüche 9, in denen der Besteckkorb verstärkt benetzt ist und an die sich die Teile anlegen.The intersecting webs 1 to 4 are each at the crossing points 5 to 8 - of which the figure 1 a crossing point 7 as an example in the view of Cross-section or profile shows - preferably designed inclined downwards in the manner of a cone 11 in order to improve the drying result for the cutlery and / or small dishes compared to the known inserts with straight webs. The figure 1 nevertheless shows existing problem zones where rinsing liquid 10 remains despite inclined webs and cannot flow off by itself. These are primarily the horizontal surfaces of the insert and the corners of the individual openings 9, in which the cutlery basket is wetted and to which the parts rest.

Daher sind gemäß Figur 2 die Stege 1 bis 4 derart geneigt ausgebildet, dass sie jeweils einen rautenförmigen Querschnitt aufweisen, wobei sie an den Kreuzungspunkten 5 bis 8 - von denen wiederum nur der Kreuzungspunkt 7 beispielhaft in der Ansicht des Querschnitts bzw. des Profils dargestellt ist - ein Profil nach Art einer Doppelpyramide 12 aufweisen. Dadurch erfolgt eine Optimierung des Trocknungsergebnisses und der Zeit für die Trocknungsphase, indem die Spülflüssigkeit 10 über alle schrägen Flächen der Raute nach unten gezogen wird - angedeutet durch den Pfeil - , d.h. das von allein abfließen kann. Die Trocknungsverbesserung wird zusätzlich unterstützt durch den jeweils im Bereich der Kreuzungspunkte 5 bis 8 durch Radien 23 abgerundet ausgebildeten Durchbruch 9, der stellvertretend für die Gestaltung aller anderen Durchbrüche des Besteckkorbes gezeigt ist. Die mit Spülflüssigkeit benetzten Anlegestellen in den "Ecken" sind aus Gründen des Abflusses nach unten nicht mehr vorhanden, die am Besteckkorb anlehnenden Besteckteile und/oder Kleingeschirr sind eher trocken. Das rasche und selbstständige Ableiten der Spülflüssigkeit auf Grund der im Querschnitt eine Rautenform aufweisenden geneigten Stege und die Reduzierung der Anlegestellen auf Grund der abgerundeten Durchbrüche optimieren nicht nur die Trocknungsleistung, sondern verbessern außerdem in vorteilhafter Weise auch die Reinigungsleistung eines Spül- und Trocknungsprogramms einer Geschirrspülmaschine und verhindern das Entstehen von Trocknungsflecken auf den Besteckteilen.Therefore, according to figure 2 the webs 1 to 4 are inclined in such a way that they each have a rhombic cross section, whereby at the crossing points 5 to 8 - of which only the crossing point 7 is shown as an example in the view of the cross section or profile - a profile according to Art have a double pyramid 12 . This results in an optimization of the drying result and the time for the drying phase, in that the rinsing liquid 10 is drawn down over all inclined surfaces of the rhombus—indicated by the arrow—ie it can flow off by itself. The improvement in drying is additionally supported by the opening 9 rounded off by radii 23 in the area of the crossing points 5 to 8, which is shown as representative of the design of all other openings in the cutlery basket. The contact points in the "corners" wetted with washing-up liquid are no longer available for reasons of drainage, the cutlery and/or small crockery leaning against the cutlery basket are rather dry. The rapid and automatic drainage of the dishwashing liquid due to the inclined webs having a rhombic cross-section and the reduction in the contact points due to the rounded openings not only optimize the drying performance, but also advantageously improve the cleaning performance of a washing and drying program of a dishwasher and prevent the formation of drying spots on the cutlery.

Figur 3 zeigt eine andere Variante der Einrichtung mit Mitteln zur Verbesserung der Trocknungsleistung. Die Einrichtung umfasst - ebenfalls wie die Figur 1 und die Figur 2 - einen Einsatz, der im Ausführungsbeispiel als Besteckkorb 13 zur Bestückung mit Besteckteilen und/oder Kleingeschirr - im gewählten Beispiel mit Löffeln 14 und 15 unterschiedlicher Länge bzw. Größe - ausgebildet und in einer Geschirrspülmaschine in einem Geschirrkorb lose angeordnet oder daran fest oder beweglich angebracht ist. Der prinzipielle Aufbau eines Besteckkorbes mit Seitenwänden, Boden und/oder Abdeckung entspricht ebenso dem im Patent DE 36 41 020 beschriebenen Einsatz. figure 3 shows another variant of the device with means for improving the drying performance. The facility includes - likewise like that figure 1 and the figure 2 - A use of the embodiment as a cutlery basket 13 for loading with cutlery and / or small dishes - in the example chosen with spoons 14 and 15 of different lengths or sizes - formed and in a Dishwasher loosely arranged in a dish rack or attached to it in a fixed or movable manner. The basic structure of a cutlery basket with side walls, base and/or cover also corresponds to that in the patent DE 36 41 020 described use.

Der Besteckkorb 13 umfasst in dem gewählten Beispiel insgesamt drei Einsatzfächer 16, 17 und 18, die durch zwei vertikal verlaufende Trennwände 19 und 20 voneinander abgegrenzt sind. Prinzipiell kann der Besteckkorb auch eine andere Anzahl - zumindest aber zwei getrennte - Fächer haben. Erfindungsgemäß weisen zumindest zwei Einsatzfächer, beispielseise hier die Einsatzfächer 16 und 17 oder 17 und 18 in verschiedenen Höhen angeordnete Fachböden 16' und 17' oder 17' und 18' auf. So wird der lange Löffel 14 - wie gezeigt - in das Einsatzfach 16 mit zugehörigem Fachboden 16' und längerer Nutzhöhe eingestellt, so dass er auf dem Fachboden 16' sicher aufsteht. Auch ein Einstellen des Löffels 14 in das Einsatzfach 18, dessen Fachboden 18' auf gleicher Höhe mit dem des Einsatzfaches 16' liegt, ist möglich. Demgegenüber dient das in der Mitte gelegene Einsatzfach 17 zur Aufnahme bzw. zum Einstellen des kurzen Löffels 15, damit auch dieser sicher auf dem zugehörigen Fachboden 17' aufsteht.In the selected example, the cutlery basket 13 comprises a total of three insert compartments 16, 17 and 18, which are separated from one another by two vertically running partitions 19 and 20. In principle, the cutlery basket can also have a different number - but at least two separate - compartments. According to the invention, at least two insert compartments, for example insert compartments 16 and 17 or 17 and 18 here, have shelves 16' and 17' or 17' and 18' arranged at different heights. As shown, the long spoon 14 is placed in the insert compartment 16 with the associated compartment floor 16' and a longer usable height, so that it stands up securely on the compartment floor 16'. It is also possible to place the spoon 14 in the insert compartment 18, the shelf 18' of which is at the same level as that of the insert compartment 16'. On the other hand, the insert compartment 17 located in the middle is used for receiving or for adjusting the short spoon 15, so that this also stands up securely on the associated compartment floor 17'.

Vorzugsweise weisen die drei Einsatzfächer 16 bis 18 auf unterschiedlichen Höhen gelegene Fachböden 16' bis 18' auf, damit sich verschiedene, partiell in den einzelnen Sektionen anpassbare Nutzhöhen für den Besteckkorb 13 ergeben. Insgesamt entsteht durch die in ihrer Höhe individuellen Fachböden 16' bis 18' der Einsatzfächer 16 bis 18 ein Besteckkorbboden mit unterschiedlicher Nutzhöhe. Dadurch ist eine Anhebung und eine Absenkung des Besteckkorbbodens in ausgewählten Sektionen möglich, um das Trocknungsresultat bei Bestückung des Einsatzes besonders mit Besteckteilen und/oder mit Kleingeschirr unterschiedlichster Länge, Größe, Form usw. zu optimieren. Die Trocknungsverbesserung gelingt durch die erfindungsgemäße variable Gestaltung des Einsatzes, indem durch Ausbildung eines unterschiedliche Nutzhöhen aufweisenden Besteckkorbbodens der Spülflüssigkeitstropfenabfluss begünstigt wird. Die auf den Fachböden 16' bis 18' in jedem Fall aufstehenden Besteckteile und/oder Kleingeschirr sind eher trocken. Das rasche und selbständige Ableiten der Spülflüssigkeit auf den in entsprechende Einsatzfächer 16 bis 18 mit geeigneter Höhe der zugehörigen Fachböden 16' bis 18' optimiert nicht nur die Trocknungsleistung, sondern verbessert außerdem in vorteilhafter Weise auch die Reinigungsleistung eines Spül- und Trocknungsprogramms einer Geschirrspülmaschine.The three insert compartments 16 to 18 preferably have shelves 16' to 18' at different heights, so that there are different usable heights for the cutlery basket 13 that can be partially adjusted in the individual sections. Overall, the shelves 16' to 18' of the insert compartments 16 to 18, which have individual heights, result in a cutlery basket base with a different usable height. This makes it possible to raise and lower the bottom of the cutlery basket in selected sections in order to optimize the drying result when the insert is loaded with cutlery and/or small dishes of the most varied lengths, sizes, shapes, etc. The improvement in drying is achieved by the variable design of the insert according to the invention, in that the draining of the drops of washing liquid is promoted by the formation of a cutlery basket bottom having different usable heights. The pieces of cutlery and/or small crockery standing on the shelves 16' to 18' are rather dry. The rapid and automatic drainage of the washing liquid to the corresponding insert compartments 16 to 18 with a suitable height of the associated shelves 16' to 18' not only optimizes the drying performance, but also improves in advantageously also the cleaning performance of a washing and drying program of a dishwasher.

Die vorbeschriebenen, erfindungsgemäßen Mittel führen dazu, dass Flüssigkeitstropfen selbständig und von allein ablaufen und somit die Bildung unerwünschter Trocknungsflecken auf den Besteckteilen und/oder dem Kleingeschirr verhindert wird. Eine noch bessere Trocknungsleistung und eine Verkürzung der Trocknungsphase als bei bekannten Einrichtungen ist die Folge.The above-described agents according to the invention result in drops of liquid running off automatically and thus the formation of undesirable drying spots on the cutlery and/or small dishes is prevented. The result is an even better drying performance and a shorter drying phase than in known devices.
